FAQ
I. Related to the Basic Principle
1. Question: What is the working principle of the photovoltaic laminating and welding machine?
Answer: The photovoltaic laminating and welding machine mainly realizes the precise welding of busbars and solar cells through precisely controlled heating and pressing methods. It uses appropriate welding heat sources (such as laser, thermocompression, etc.) to melt the welding materials and achieve reliable connections under the action of pressure, forming a stable electrical circuit structure, thus completing the electrical connection link among the solar cells in the photovoltaic module.
2. Question: What technologies does it rely on to achieve precise welding?
Answer: It relies on high-precision positioning technologies, such as a visual recognition system to accurately position the solar cells and busbars. It also has precise control technologies for parameters such as temperature, pressure, and time to ensure that all conditions during the welding process are stable and appropriate, guaranteeing the quality and accuracy of the welding spots.
II. Equipment Performance Aspects
1. Question: How high can the welding precision of the photovoltaic laminating and welding machine reach?
Answer: Generally, the position deviation of the welding spots can be controlled within a few tenths of a millimeter. The specific value varies depending on different equipment models, but all can well meet the strict requirements for welding precision in high-quality production of photovoltaic modules, ensuring accurate connection of solar cells and good electrical conduction of the circuit.
2. Question: How fast is the welding speed?
Answer: Different grades of equipment have different speeds. Commonly, dozens to hundreds of welding spots can be completed per minute. Some high-end equipment is even faster, which effectively guarantees production efficiency and enables a large number of solar cells to be welded in a short time.
III. Related to the Scope of Application
1. Question: What specifications of solar cells can it be applied to for welding?
Answer: It can be compatible with the welding of various common-sized solar cells, such as the conventional 156mm×156mm, 166mm×166mm, 182mm×182mm, 210mm×210mm, etc. And by adjusting parts such as fixtures, it can also adapt to the welding of some special-sized solar cells.
2. Question: Are there any requirements for welding materials?
Answer: It can use a variety of common busbars, welding ribbons and other welding materials. For example, conventional tinned copper ribbons can be well welded as long as the materials meet the basic quality and specification standards.
IV. Operation and Use Aspects
1. Question: Is the operation complicated? What kind of training is required?
Answer: The operation is not complicated. Operators generally need to be familiar with the functions of the equipment's operation panel, master how to input welding parameters (such as temperature, time, pressure, etc.), understand the loading and unloading processes, and know simple emergency handling for faults. Usually, after receiving several days of professional training provided by the equipment manufacturer and practicing actual operations, they can start operating the equipment.
2. Question: How to prepare before starting up the equipment?
Answer: Before starting up, check whether the components of the equipment are firmly connected, whether there are any damages or short circuits in the electrical circuits, confirm whether the welding heads are clean and intact, check whether the air source pressure is normal, and also ensure that the solar cells and welding materials to be welded are prepared completely and of qualified quality.
V. Maintenance and Repair Aspects
1. Question: What work needs to be done for daily maintenance?
Answer: Daily maintenance includes cleaning the dust and debris on the surface of the equipment, regularly cleaning the residues on the welding heads, checking the lubrication conditions of each transmission component and adding lubricating oil in a timely manner, checking whether there are abnormal heating or aging phenomena in electrical components, and also paying attention to whether the various sensors of the equipment are working normally.
2. Question: How often is it appropriate to conduct a comprehensive overhaul?
Answer: It is recommended to conduct a comprehensive overhaul every six months to one year. The focus is to check the wear conditions of the mechanical structure, the stability of the control system, and the accuracy of the welding parameters. However, if the equipment is used frequently or there are abnormal situations, the comprehensive overhaul can be carried out in advance as appropriate.
