Description

technical field [0001] The invention belongs to the field of equipment design, and in particular relates to industries such as new energy solar cell module manufacturing and semiconductor device packaging, and in particular to a solar cell sheet welding strip dismantling device. Background technique [0002] A solar photovoltaic module is a renewable energy device that converts light energy into electrical energy. With the development of industrialization, human's demand for energy is increasing rapidly, and the crisis of global energy shortage is becoming increasingly prominent due to the continuous reduction of traditional energy due to its non-renewability; It has caused serious ground, water and air pollution, and brought many serious problems to the living environment of human beings. In order to solve the contradiction between increasing energy demand and decreasing traditional energy reserves, in order to meet human demand for energy and reduce the damage to the envi...

Problems solved by technology

And because the solar cell is a very thin (about 180um thick) silicon material, and the silicon material itself is very brittle, it is easy to cause the corner of the solar cell to drop, crack or crack due to improper operation, pressure of the soldering iron, and temperature difference

Therefore, it is easy to damage the solar cells during the disassembly process of the solar cell ribbon.

[0007] At present, there is no relevant patented technology or equipment that can solve the difficulty of dismantling the solar cell ribbon. Manufacturers usually use electric soldering irons to directly heat the solder ribbon, and then forcibly remove the solder ribbon on the solar cell sheet by hand.

Due to this disassembly method, in the process of directly heating the solar cells with an electric soldering iron, it is difficult to control the heating temperature, heating time and the force directly applied to the solar cells, which can easily lead to cracks and cracks in the cells, and the high temperature ( Generally around 360 degrees) Heating the solar cell for a long time will also damage the internal structure of the solar cell and seriously affect the electrical performance of the solar cell; secondly, use two hands to press the solar cell, heat the soldering strip with a soldering iron, and separate the soldering strip , the operation is more difficult, and it is easy to cause the solar cell to break, or damage the positive and negative materials of the solar cell, so that it cannot be welded again; The requirements are very high, the efficiency is very low, and the probability of disassembly after repair is high

In this way, the scrap rate of solar cells is very high, and solar cells, as the core device of solar photovoltaic modules, are the most important part of the cost of solar photovoltaic modules, which will bring significant losses to enterprises.
