The fully automatic multifunctional lap-welding machine relies on high-precision sensing, transmission, and temperature control systems, placing extremely high demands on the operating environment and equipment status. Comprehensive checks must be completed before startup to eliminate any potential hazards.
The operating environment must meet PV production cleanliness standards; the workshop must be kept dust-free, dry, and well-ventilated, with an ambient temperature maintained between 18°C and 28°C and relative humidity controlled between 40% and 60%. Excessive humidity can cause electrical module leakage and ribbon oxidation, while low humidity can generate static electricity that damages the delicate structure of the solar cells. Dust accumulation can clog sensors, ribbon feed tracks, and flux nozzles, leading to ribbon feed jams and positioning failures. The equipment must be installed on a level, stable, and hardened surface. The grounding system must be intact and reliable, with grounding resistance meeting equipment standards to effectively eliminate static interference and protect the solar cells and electronic control systems. Placing or operating the equipment in environments with corrosive gases, heavy oil fumes, or intense vibration is strictly prohibited.
The comprehensive equipment inspection must cover the four core modules: electrical, transmission, sensing, and welding. Verify that all main power, signal, and data cable connections are secure and free from aging, damage, or loose contacts; ensure electrical cabinet cooling fans and ventilation filters are clean and unobstructed by dust; and confirm that emergency stop buttons and safety interlock switches are responsive and functional. Systematically inspect the automatic ribbon feeding mechanism, cutter assembly, bonding guide rails, and servo drive system to ensure smooth operation without jamming, misalignment, or looseness; check that cutter blades are intact and free of defects to prevent uneven cutting lengths, burrs, or deformation of the ribbon. Calibrate visual positioning sensors and photoelectric probes, cleaning any dust or stains from their surfaces to ensure accurate recognition and stable signal transmission. Finally, thoroughly clean the welding table, welding head, and pressure pin assembly to remove welding slag, debris, and dust, ensuring the work area is clear of obstructions and foreign objects.
Verify material compatibility in advance; select photovoltaic-grade ribbons and busbars that match the specific equipment model and solar cell specifications, ensuring surfaces are clean and free from oxidation (blackening), deformation, or oil and impurities. Use halogen-free, eco-friendly flux designed for photovoltaics, checking that the concentration meets standards and the fluid is free from crystallization, sedimentation, or contamination; filter out impurities beforehand to prevent clogging of spray lines and nozzles. Additionally, verify equipment parameters against specific cell technologies (such as PERC, TOPCon, or BC) and confirm the ribbon/busbar bonding process to prevent mismatches between materials and equipment settings.
This equipment integrates multiple automated functions—including feeding, cutting, bonding, spraying, welding, and alignment correction—with highly interdependent parameters; a deviation in a single parameter can lead to batch quality issues. Arbitrary application of parameters or blind commissioning is strictly prohibited; precise calibration must be performed according to standard procedures.
Do not proceed directly to production after startup; a no-load test run of at least five minutes is required to verify the operational status of each independent module. Before proceeding to the first-article test weld, verify the uniformity of automatic ribbon feeding speed, cutting precision, ribbon alignment accuracy, flux spraying stability, and the coordination of the welding head's lifting and pressing actions; ensure there are no abnormal noises, mechanical binding, parameter errors, or positioning deviations, and confirm smooth module interaction.
First-article production is a critical stage for parameter calibration; test production must utilize the same batch of solar cells, ribbons, and busbars. Following the initial lap welding, conduct a comprehensive inspection of ribbon alignment, solder joint appearance, bonding tightness, and cell integrity. Fine-tune parameters based on inspection results to establish and lock in standard process parameters, thereby preventing arbitrary changes during mass production.
Core process parameters require precise matching and coordinated control. Welding temperatures must be set appropriately based on ribbon specifications and cell types—typically within the 200°C–340°C range. Excessively low temperatures result in insufficient flux activation and poor solder wetting, leading to cold joints or detachment; conversely, excessively high temperatures cause ribbon oxidation (blackening), thermal damage to cells, micro-cracks, and excessive module power degradation. Strictly control welding hold time, heating duration, and pressing force; excessive pressure can crush cells or cause micro-cracks, while insufficient pressure leads to loose bonding and weak solder joints. Additionally, precisely configure automatic ribbon feeding speed, cutting length, and lap offset compensation parameters—integrated with a visual correction system—to eliminate issues such as ribbon misalignment, lap displacement, and uneven lengths.
Flux spraying parameters require refined control to ensure uniform and optimal spray coverage and volume, preventing excessive residue that could corrode cells and backsheets, or insufficient application that leads to poor welding wetting. Regularly calibrate spray frequency and flow rates, and promptly clear nozzle crystallization or blockages to ensure the spraying system operates consistently and reliably. III. Operational Guidelines for Automated Production
Although the fully automatic multifunctional lap-welding machine is capable of autonomous operation, standardized monitoring and real-time oversight are mandatory. Unattended operation is strictly prohibited to prevent batch defects or equipment failures caused by malfunctions in the automation modules.
Loading and unloading procedures must be standardized and precise; battery strings must be positioned with strict attention to polarity orientation to prevent short circuits or welding failures caused by reversed polarity. Manual loading assistance must be gentle—dragging, bumping, or crushing of battery cells is prohibited—to minimize the risk of micro-cracks or breakage. Raw material rolls (ribbons and busbars) must be installed neatly with appropriate tension settings to prevent stretching, tangling, or misalignment during feeding, thereby ensuring continuous and stable automatic material delivery.
The equipment's multifunctional operational status must be monitored in real-time throughout production, with a focus on visual positioning, automatic alignment correction, temperature control systems, and material feeding/cutting systems. Operators must watch for issues such as feeding jams, cutting anomalies, alignment offsets, uneven coating, temperature fluctuations, or pressing deviations, and listen for any abnormal operating sounds. If parameter errors, mechanical anomalies, or welding quality deviations occur, the emergency stop button must be pressed immediately to halt the machine for troubleshooting; operating the machine with faults is prohibited to prevent the production of defective batches and accelerated component wear.
During automated operation, it is strictly forbidden to open protective covers or reach into high-risk moving parts—such as drive mechanisms, welding heads, or cutting blades—or to arbitrarily modify operating parameters or clear internal welding slag and debris. These measures prevent mechanical crushing or high-temperature burns and avoid system parameter errors or positioning inaccuracies caused by human interference. During production breaks, welding slag, dust, and waste materials must be promptly cleared from the workbench surface and the area surrounding the welding head to maintain a clean workspace and ensure the precise operation of sensing and drive modules.
Leveraging the equipment's multifunctional welding capabilities, a targeted quality inspection mechanism must be established. This mechanism should focus on three core areas—lap-joint precision, weld-point quality, and battery cell condition—to promptly identify process defects and strictly control product quality. Focus inspection on the quality of ribbon and busbar overlaps; compliant products must feature precise overlap positioning with no misalignment, lifting, or gaps. Ribbons must lie flat against the cell surface, free from stretching, deformation, wrinkling, or displacement. Solder joints must be bright and full, with uniform wetting and no defects such as cold joints, missed welds, false welds, excess solder buildup, or blackening/oxidation; adhesion must meet standards, ensuring no risk of loosening or detachment. Simultaneously, inspect each cell individually to prevent quality issues—such as micro-cracks, breakage, or edge chipping—caused by abnormal welding pressure or temperature.
Address common defects in automated production with precision: for cold joints or insufficient adhesion, fine-tune welding temperature and dwell time, and check flux application uniformity; for ribbon misalignment, recalibrate the visual positioning system and automatic correction parameters, and clean sensor probes; for excessive solder spatter or blackened joints, optimize flux dosage and welding temperature, and clear debris from nozzles and the welding platform; for batch micro-cracking, immediately verify welding pressure, welding head flatness, and feeding stability.
Strictly regulate defect management and rework procedures; mark defective items separately and store them in designated zones to prevent mixing with compliant products. Rework must adhere to photovoltaic process standards, strictly controlling temperature, frequency, and handling force to avoid secondary welding damage to cells or accelerated power degradation; rough or non-compliant rework methods are strictly prohibited. Additionally, perform spot checks on circuit continuity to eliminate short circuits or open circuits caused by welding errors, ensuring stable electrical performance.
The fully automatic multi-functional tabber-stringer comprises multiple modules and operates with high precision; meticulous maintenance is key to ensuring stable, coordinated multi-functional operation, extending equipment lifespan, and maintaining production accuracy. A comprehensive maintenance regimen—including daily cleaning, weekly calibration, and monthly inspections—must be implemented. Routine cleaning and maintenance must be carried out during every shift. After the equipment is shut down and disconnected from the power supply, use dry compressed air (at a pressure of 0.5 MPa or lower) to clear dust, welding slag, and scrap material from the interior. Wipe precision components—such as the welding head, pressure pins, guide rails, vision probes, and nozzles—with a soft, lint-free cloth. Do not use water or corrosive cleaning agents (such as strong acids or alkalis) on precision electrical components like electrical cabinets, servo motors, sensors, or temperature control modules; this prevents damage caused by water ingress, corrosion, or short circuits. At the end of each shift, empty waste flux and scrap residues, clear crystallized deposits from the spraying lines, and replace aging filter components to prevent line blockages.
Scheduled specialized inspections must be performed on time. Check the wear on tape-feeding wheels, cutting blades, drive belts, and guide rails daily; tighten loose screws and connectors to ensure smooth transmission. Conduct weekly comprehensive calibrations of the temperature control, vision positioning, and automatic alignment systems; adjust parameter deviations to ensure precision in welding, alignment, and cutting. Perform monthly inspections of electrical circuits, pneumatic systems, and the flux supply system to identify hazards such as aging wiring, air leaks, or line blockages, and promptly replace worn-out consumables like cutting blades, suction cups, seals, and nozzles.
For long-term equipment shutdowns, implement proper preservation measures: disconnect the main power supply, clear debris and residual flux from the interior, cover the machine with a dust- and moisture-proof sheet, and store it in a dry, well-ventilated environment to prevent moisture-induced rust, seizing, or component failure. Before restarting equipment that has been idle for a long period, fully inspect and calibrate module parameters, and conduct a successful no-load test run before resuming production. All maintenance work must be performed with the power disconnected and the machine shut down; safety warning signs must be displayed. Performing maintenance on live equipment or unauthorized disassembly is strictly prohibited.
The fully automatic multifunctional lap-welding machine for PV ribbon and busbar integrates high-temperature welding, mechanical transmission, electrical control, and pneumatic operation. It presents safety risks such as high-temperature burns, mechanical crushing injuries, and electrical leakage; operators must strictly adhere to safety operating procedures. Operators must be certified and proficient in the equipment's multi-functional operating procedures and safety guidelines. They are required to wear appropriate anti-static and heat-resistant protective gear; operating without certification, violating procedures, or working under the influence of alcohol is strictly prohibited. During operation, hands and limbs must be kept away from high-risk moving parts—such as cutting blades, drive tracks, welding heads, and lifting/clamping mechanisms. Unauthorized removal or bypassing of safety doors and protective devices is strictly forbidden to eliminate safety hazards. The workshop must be well-ventilated to ensure the timely extraction of welding fumes and a safe working environment.
In the event of malfunctions—such as abnormal noises, jamming, smoke, electrical leakage, temperature anomalies, parameter errors, or batch defects—operators must immediately press the emergency stop button and cut off the main power supply. Inspection and maintenance should only commence after the equipment has fully stopped and high-temperature components have sufficiently cooled. Disassembling the machine while powered, touching welding components while hot, or forcibly operating a faulty machine is strictly prohibited to prevent the escalation of faults or safety accidents. If sudden batch quality issues arise, the machine must be stopped immediately and the affected batch quarantined; a comprehensive investigation into materials, parameters, and equipment module faults is required, and production may only resume after all hazards have been thoroughly rectified.
A routine safety inspection mechanism must be established to regularly verify the effectiveness of grounding systems, insulation, emergency stop systems, ventilation/cooling systems, and pneumatic safety devices. Safety hazards—such as electrical aging, missing guards, or component failures—must be promptly addressed to ensure the equipment's long-term safe, stable, and efficient operation.
