[0001] The present invention belongs to the technical field of solar cell manufacturing, and particularly relates to a plating device for solar cells and a using method thereof. Background Art

[0002] As a new method for preparing electrodes of solar cells, electroplating technology has been increasingly widely studied. As a relatively promising method for preparing electrodes, electroplating can not only greatly reduce the cost in the production process of solar cells, but also the electrodes prepared by electroplating technology have a higher aspect ratio and better conductivity compared with the electrodes prepared by traditional screen printing. The internal resistance of the battery is lower, and the shading loss can be reduced, thereby effectively improving the photoelectric conversion efficiency of the solar cell.

[0003] In the current electroplating device, during the electroplating process, a fixture is used to clamp the solar cell and place it in the electroplating bath for electroplating. During the electroplating process, the contact part between the solar cell and the fixture cannot be electroplated, thus affecting the electroplating quality of the solar cell. And after electroplating, most of the solar cells are taken out and placed in a draining basket for static draining. The operation is cumbersome, and the electroplating solution adhered to the surface of the solar cell cannot be quickly removed. Summary of the Invention

The same top plate 19 is sleeved on the two limit frames 18. A plurality of third through grooves 21 are opened on the bottom of the top plate 19. Through the combined action of the first electric push rod 11, the side plate 12, the second electric push rod 14, the support plate 15, the third electric push rod 17 and the top plate 19, the plating is carried out by clamping the solar cell panel up and down, and during the plating process, it is changed to the front and back clamping method for plating, so that the solar cell wafers can be plated in all directions without leaving plating dead corners, improving the plating quality.

[0027] Specifically, universal wheels 2 are fixedly connected to the four corners of the bottom of the electroplating tank box 1. A controller 3 is arranged on the front surface of the electroplating tank box 1. The controller 3 can be a conventional known device such as a computer for control. The controller 3 is electrically connected to the electroplating tank box 1, the hydraulic rod 5, the first electric push rod 11, the second electric push rod 14, and the third electric push rod 17 through wires. On both sides of the bottom of the two brackets 4, telescopic rods 7 are fixedly connected. The two telescopic rods 7 are in a group. The bottoms of the two groups of telescopic rods 7 are respectively fixedly connected to the tops of the two movable bars 6. On the opposite sides of the two movable bars 6, two reinforcing bars 10 are fixedly connected. The two reinforcing bars 10 are in a group.

By arranging the telescopic rods 7 and the reinforcing bars 10, the stability of the movable bar 6 and the support plate 9 is improved respectively.

[0028] Specifically, elastic pads 22 are fixedly connected in a plurality of first through grooves 13, a plurality of second through grooves 16, and a plurality of third through grooves 21. By arranging the elastic pads 22, a protective effect can be achieved when clamping the solar cell. Dust-proof nets 25 are fixedly connected in a plurality of air inlet pipes 24. By arranging the dust-proof nets 25, dust can be prevented from being blown onto the surface of the electroplated solar cell. Fixing bolts 20 are threadedly inserted through both ends of the top plate 19. One ends of the two fixing bolts 20 are respectively lapped with one side of the two limiting frames 18. By arranging the fixing bolts 20, a fixing effect can be achieved on the top plate 19 sleeved on the limiting frames 18.

[0029] A using method of a solar cell electroplating device is as follows:

[0030] Step 1: Remove the top plate 19 from the limiting frame 18, insert the solar cell through the first through groove 13 on the side plate 12, and place it in the second through groove 16 on the support plate 15. The hydraulic rod 5 extends, and the solar cell is sunk into the electroplating tank box 1 for electroplating.

[0031] Step 2: After electroplating for a period of time, the first electric push rod 11 contracts, driving the side plate 12 to move, clamping the solar cell in the first through groove 13. The second electric push rod 14 and the third electric push rod 17 extend, and the support plate 15 and the top plate 19 are separated from the solar cell, and electroplating continues.

[0032] Step 3: After electroplating is completed, the hydraulic rod 5 contracts, the solar cell rises out of the electroplating tank box 1, moves below the wind cover 23, and the fan 26 works to blow air onto the surface of the solar cell, so that the electroplating solution adhering to the surface of the solar cell can quickly drip into the electroplating tank box 1.

[0033] Working principle and usage process of the present invention: When the present invention is in use, connect the device to an external power source, remove the top plate 19 from the limit frame 18, insert the solar cell through the first through slot 13 on the side plate 12 into the second through slot 16 on the support plate 15. Repeat the above operation to complete the installation of the solar cell. Then, sleeve the top plate 19 on the limit frame 18 and tighten the fixing bolt 20. One end of the fixing bolt 20 tightly abuts against the limit frame 18. The third electric push rod 17 contracts, driving the top plate 19 to descend, so that the top of the solar cell is clamped into the third through slot 21 to complete the clamping and fixing of the solar cell. The first electric push rod 11 extends, pushing the side plate 12 to move, separating the side plate 12 from the solar cell. Then, the hydraulic rod 5 extends, and the movable strip 6 descends. The movable strip 6 drives the support plate 9 to descend through the fixed rod 8, submerging the solar cell into the electroplating tank 1 for electroplating. After electroplating for a period of time, the first electric push rod 11 contracts, driving the side plate 12 to move, clamping the solar cell in the first through slot 13. The second electric push rod 14 and the third electric push rod 17 extend, separating the support plate 15 and the top plate 19 from the solar cell, and continue electroplating;

[0034] After electroplating is completed, the hydraulic rod 5 contracts, driving the solar cell to rise out of the electroplating tank 1 through the movable strip 6 and the support plate 9, and moving it below the wind hood 23. The electroplating solution adhering to the surface of the solar cell drips into the electroplating tank 1 under the action of its own gravity, and the fan 26 works to blow air on the surface of the solar cell, blowing the electroplating solution to drip quickly. When removing the solar cell, the second electric push rod 14 contracts to drive the support plate 15 to rise, so that the second through slot 16 abuts against the bottom of the solar cell. The first electric push rod 11 extends, pushing the side plate 12 to move to loosen the clamping of the solar cell, but the solar cell still remains in the first through slot 13. Then, the top plate 19 can be removed and the solar cell can be taken out.

[0035] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
