[0006] 2. When etching the battery cell, due to the lack of a structure for classifying and recycling the debris generated after the etching process, the debris after the etching process cannot be classified and recycled, which reduces the flexibility of the etching process. Summary of the invention

[0007] The purpose of the present invention is to provide an existing photovoltaic cell etching device and a method for using the same, which has the following advantages:

[0008] 1. When etching the battery cell, the battery cell can be quickly and automatically removed and limited due to the fast and automatic stripping and limiting structure, which improves the efficiency of battery cell processing;

[0009] 2. When etching the battery cell, the debris generated after the etching process can be classified and recycled due to the structure, so the debris after the etching process can be classified and recycled, which improves the flexibility of the etching process.

[0010] The above technical purpose of the present invention is achieved through the following technical solutions: a photovoltaic cell etching device, including an entry and exit mechanism and a processing mechanism, the processing mechanism is bolted to the bottom of the entry and exit mechanism, the entry and exit mechanism includes a moving component, a detachment component, a positioning component and a limit component, the detachment component is bolted to the top of the moving component, the positioning component is clamped to the bottom of the moving component, the limit component is slidably connected to the top of the positioning component, the processing mechanism includes an etching component, an adsorption component, an interception component and a screening component, the etching component is bolted to the rear side of the bottom of the moving component, the adsorption component is clamped to the inner side of the etching component, the interception component is bolted to the inner side of the etching component, and the screening component is clamped to the inner side of the interception component.

[0011] By adopting the above technical solution, an access mechanism and a processing mechanism are provided. The access mechanism can quickly access photovoltaic cells, and the processing mechanism can classify and recycle debris generated during etching.

[0012] The present invention is further configured as follows: the moving assembly comprises a moving frame, a guide bucket plate and a moving plate, the guide bucket plate is bolted to the bottom of the moving frame, and the moving plate is bolted to the rear side of the moving frame.

[0030] S2. Waste recovery: First, the processing mechanism is powered on and started, and then the etching liquid delivery device is connected to the solenoid valve to deliver the etching liquid to the etching box until the etching box is filled with etching liquid. After that, when the battery cell falls into the etching liquid in the etching box along with the entry and exit mechanism, the etching box will etch the battery cell. When debris is generated during the process, the recovery electromagnet will transmit the magnetic force to the magnetic rod, and then the magnetic rod will collect the iron metal debris, and then the interception net will intercept other debris, and then the vacuum pump will pump the outside air to the exhaust pipe, and then the air will be transported from the exhaust pipe to the interception net, driving the accumulated debris upward, so that the iron metal debris that has not been adsorbed can be moved back to the magnetic rod and adsorbed until the debris recovery is completed.
