Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic electroplating, and in particular to a photovoltaic cell single-sided or double-sided horizontal electroplating line capable of overall stripping. Background Art

[0002] In the photovoltaic industry, the high cost of photovoltaic silver paste has always been a pain point. It is the largest non-silicon cost of photovoltaic cells. In addition, the silver paste used in photovoltaic cells mainly relies on imports, which greatly restricts the development of my country's photovoltaic industry.

[0003] Based on the above reasons, it is an urgent need for the photovoltaic industry to use low-value copper metal to replace expensive photovoltaic silver paste. Photovoltaic cell grid copper electroplating technology is a disruptive new cost-reduction technology and new direction for completely silver-free photovoltaic cells.

[0004] Currently, many manufacturers are conducting photovoltaic copper electroplating verification. The electroplating equipment mainly adopts horizontal, vertical and plug-in structures. Among them, the horizontal type has high production efficiency and stable operation, and is the key research area in the industry.

[0005] Patent CN115637481A proposes a single-sided horizontal electroplating device, which uses a probe as a cathode. The probe and the battery cell run synchronously for conduction, but its positioning requirements are high, there is a movement difference between the probe and the battery cell, and the contact stability is poor; Patent CN217733298U proposes a horizontal electroplating device, which uses a flexible roller for conduction, but the problem of plating on the roller surface is difficult to solve; Patent CN113493923A proposes a single-sided and double-sided electroplating device, which uses a water-absorbent roller for conduction, and the roller also has the problem of plating on the surface that is difficult to solve. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a single-sided or double-sided horizontal electroplating line for photovoltaic cells that can be stripped as a whole, which can realize single-sided or double-sided electroplating options. By designing the movement mode of the battery cells, changing the cathode conductive structure and the overall stripping structure, efficient contact and conduction of the battery cells can be achieved, while reducing the fragmentation rate.

The liquid inlet parallel four-bar mechanism 25 is connected to the liquid inlet fixed frame 23.

[0048] Among them, the liquid inlet mechanism 2 is first rotated into a vertical direction through the liquid inlet parallelepiped mechanism 25 and is located on the surface of the electroplating liquid. After the battery cell 21 is adsorbed onto the pneumatic adsorption slide 22, the liquid inlet mechanism 2 rotates 90 degrees counterclockwise to immerse the battery cell 21 in the electroplating liquid; the liquid inlet transmission mechanism 24 pushes the battery cell 21 and the pneumatic adsorption slide 22 into the entrance of the horizontal electroplating line 5.

[0049] The horizontal electroplating line 5 includes an electroplating fixed frame 51, a V-shaped roller 52, an anode plate 54, a horizontal line transmission mechanism 56, and a V-shaped conveying chain 57; the electroplating fixed frame 51 is placed in the electroplating tank 1, the V-shaped roller 52 is connected to the electroplating fixed frame 51 through a bearing, the anode plate 54 and the horizontal line transmission mechanism 56 are fixed on the electroplating fixed frame 51, the horizontal line transmission mechanism 56 is connected to the V-shaped roller 52, and the V-shaped conveying chain 57 is fixed to the bottom of the electroplating fixed frame 51.

[0056] Wherein, the stripping and washing tank 4 comprises a stripping tank and a washing tank.

[0057] The conductive brush 34 includes a conductive brush fixing sheet 341, a conductive brush support frame 342, a conductive brush conductive layer 343 and a conductive brush insulating layer 344.

[0058] like Figure 2 As shown, the battery cell 21 transports gas to the liquid inlet mechanism 2 through a conveyor belt or an automated suction cup. At this time, the liquid inlet mechanism 2 is rotated to a vertical direction through the liquid inlet four-bar mechanism and is located on the surface of the electroplating liquid. After the loading is completed, the liquid inlet mechanism 2 is rotated 90 degrees counterclockwise and immersed in the electroplating liquid, and is connected to the inlet of the horizontal electroplating line 5.

[0059] like Figure 1 As shown, the liquid inlet transmission mechanism 24 is actuated to push the battery cell 21 and the pneumatic adsorption slide 22 into the entrance of the horizontal electroplating line 5. The pushing speed of the battery cell 21 is the same as the transmission speed of the horizontal electroplating line 5. The battery cell 21 is pushed into the V-shaped conveying chain 57 and the V-shaped roller 52 of the horizontal electroplating line 5. At the same time, the pneumatic adsorption slide 22 of the liquid inlet mechanism 2 is exhausted, and the battery cell 21 moves forward along the conveying chain under the transportation of the V-shaped conveying chain 57 and the V-shaped roller 52.

The limiting roller 53 is used to limit the deviation and deformation of the battery cell 21 and reduce the fragmentation rate of the battery cell 21. The conductive brushes 34 are arranged at intervals along the horizontal electroplating line 5. When the battery cell 21 passes through the conductive brush 34, the conductive brush 34 is connected to the cathode of the power supply and contacts the grid line on the surface of the battery cell 21 to achieve contact and conduction with the grid line of the battery cell 21, and copper electroplating begins. A battery cell 21 contacts one or more conductive brushes 34 at the same time; the conductive brush 34 is controlled to rotate by the conductive brush deflection mechanism 33.

[0061] like Figure 3 As shown, after the battery cell 21 is electroplated, the horizontal electroplating line 5 transports the battery cell 21 to the liquid outlet mechanism 6, and the liquid outlet mechanism 6 rotates 90 degrees counterclockwise to lift the electroplated battery cell 21 above the electroplating liquid level, completing an electroplating process.

[0062] like Figure 7 As shown, when the conductive brush 34 is plated on the contact surface of the battery cell 21 and affects the electroplating, the deplating mechanism 3 works, and all the conductive brushes 34 are lifted by the deplating telescopic mechanism 32 and moved to the deplating washing tank 4 to complete the deplating process, and the conductive brushes 34 that have been deplated are synchronously installed in the electroplating tank 1 to continue the electroplating.

[0063] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
