[0001] The utility model relates to the technical field of photovoltaic electroplating, in particular to an electroplating fixture and a side-clamping electroplating hanger. Background Art

[0002] Photovoltaic electroplating technology, as a new electrode preparation method, has been increasingly studied because it can reduce the cost of the cell production process. Electroplated electrodes have a higher aspect ratio and better conductivity than silver paste printed electrodes, which reduces the internal resistance of the cell and reduces losses such as shading, thereby further improving the photoelectric conversion efficiency of the cell.

[0003] When the battery cell is dip-plated, a plating fixture is usually used to suspend the battery cell, and then the plating fixture and the battery cell are placed in a plating tank for electroplating. After the electroplating is completed, the plating fixture and the battery cell are taken out of the plating tank, and then the battery cell is removed from the plating fixture to obtain a battery cell with a plated surface.

[0004] Currently, some electroplating fixtures are expensive and are not suitable for electroplating scenarios that require frequent replacement of battery cells. Frequent replacement of battery cells can easily damage the battery cells to be plated, thus affecting the normal electroplating process. Utility Model Content

[0035] Example 1, see Figure 1 , Figure 2 The utility model provides a plating clip, comprising:

[0036] A first clamping plate 1, wherein the first clamping plate 1 is provided with a plurality of first conductive clamping columns 4 at intervals;

[0037] and a second clamping plate 2, on which a plurality of second conductive clamping columns 5 are arranged at intervals;

[0038] And a torsion spring 3 connected between the first clamping plate 1 and the second clamping plate 2, the first conductive clamping column 4 and the second conductive clamping column 5 are suitable for clamping or releasing the sheet 100 by squeezing or loosening.

[0039] The electroplating clip mainly consists of three parts: the first clamping plate 1, the second clamping plate 2, and the torsion spring 3. It is simple to manufacture and has a low cost. The first conductive clamping column 4 and the second conductive clamping column 5 are both made of metal and can connect to the power supply. To make electroplating more accurate and prevent leakage, non-conductive coatings are applied to the first conductive clamping column 4 and the second conductive clamping column 5 except for the clamping points. Of course, the first clamping plate 1 and the second clamping plate 2 can also be correspondingly coated with non-conductive coatings. The non-conductive coatings here can be, but are not limited to, nano-ceramic coatings, polymer films, hard carbonitride films, and so on. When squeezing the first clamping plate 1 and the second clamping plate 2, the first conductive clamping column 4 and the second conductive clamping column 5 can be opened顺势 to release the sheet 100; when releasing the first clamping plate 1 and the second clamping plate 2, the first clamping plate 1 and the second clamping plate 2 are reset under the restoring force of the torsion spring 3 to clamp the sheet 100.

[0040] This embodiment further includes an opening member 6. The opening member 6 is located on one side of the opening of the torsion spring 3, and the opening member 6 is adapted to apply an external force for the first clamping plate 1 and the second clamping plate 2 to move towards each other.

[0041] Specifically, the first clamping plate 1 and the second clamping plate 2 are mirror-symmetrical with the torsion spring 3 as the center. The sides of the first clamping plate 1 and the second clamping plate 2 facing the opening member 6 are tapered. The opening member 6 is in the shape of a "冂", and the side facing the first clamping plate 1 and the second clamping plate 2 is tapered. The tapered end of the opening member 6 is adapted to apply a horizontal force to the tapered ends of the first clamping plate 1 and the second clamping plate 2. When the opening member 6 horizontally displaces towards the tapered ends of the first clamping plate 1 and the second clamping plate 2, it will squeeze one side of the first clamping plate 1 and the second clamping plate 2 to displace towards each other, while the other side will respectively drive the first conductive clamping column 4 and the second conductive clamping column 5 to open.

[0042] In this embodiment, the first conductive clamping column 4 is bolted to the outer side of the first clamping plate 1, and the second conductive clamping column 5 is bolted to the outer side of the second clamping plate 2. The bolts here can be connected to the external power supply together with the wires. The first conductive clamping column 4 and the second conductive clamping column 5 can be easily disassembled, which is suitable for electroplating scenarios that require frequent replacement and is convenient for replacement.

[0043] In this embodiment, the first conductive clamping column 4 and the second conductive clamping column 5 extend in an L shape away from the opening member 6, that is, the first conductive clamping column 4 and the second conductive clamping column 5 are L-shaped.

[0044] Embodiment 2, see Figure 3 、 Figure 4 This embodiment is another deformation of Embodiment 1, and provides an electroplating clip, including:

[0045] The first clamping plate 1, and a plurality of first conductive clamping columns 4 are provided at intervals on the first clamping plate 1;

[0046] And the second clamping plate 2, and a plurality of second conductive clamping columns 5 are provided at intervals on the second clamping plate 2;

[0047] And a torsion spring 3 connected between the first clamping plate 1 and the second clamping plate 2, the first conductive clamping column 4 and the second conductive clamping column 5 are suitable for clamping or releasing the sheet 100 by squeezing or loosening.

[0048] The electroplating clamp is mainly composed of three parts: the first clamp plate 1, the second clamp plate 2, and the torsion spring 3. The first conductive clamp column 4 and the second conductive clamp column 5 are both made of metal and can be connected to the power supply. In order to make the electroplating more accurate and prevent leakage, the first conductive clamp column 4 and the second conductive clamp column 5 are coated with a non-conductive coating except for the support point. Of course, the first clamp plate 1 and the second clamp plate 2 can also be coated with a non-conductive coating accordingly. The non-conductive coating here can be but is not limited to nano-ceramic coating, polymer film, hard carbon nitride film, etc. When squeezing the first clamp plate 1 and the second clamp plate 2, the first conductive clamp column 4 and the second conductive clamp column 5 can be opened to loosen the sheet 100; when the first clamp plate 1 and the second clamp plate 2 are loosened, the first clamp plate 1 and the second clamp plate 2 are reset under the restoring force of the torsion spring 3 to clamp the sheet 100.

[0049] One difference between this embodiment and embodiment 1 is that the opening member 6 in this embodiment is located on one side of the opening of the torsion spring 3. Figure 3 , Figure 4 The middle opening member 6 is suitable for applying an external force to the first clamping plate 1 to move it in the direction of the second clamping plate 2. The first clamping plate 1 extends along one side of the opening of the torsion spring 3, and the opening member 6 is suitable for applying a vertical force to the extended end of the first clamping plate 1. When the opening member 6 is pressed downward, it will press the extended section of the first clamping plate 1, thereby driving the first clamping plate 1 to move in the direction of the second clamping plate 2. Of course, it can be understood that the direction of the opening member 6 can also be adjusted so that it is suitable for applying an external force to the second clamping plate 2 to move it in the direction of the first clamping plate 1.

[0050] In this embodiment, the first conductive clamping column 4 is connected to the first clamping plate 1 by bolts, and the second conductive clamping column 5 is connected to the second clamping plate 2 by bolts. The first conductive clamping column 4 and the second conductive clamping column 5 are relatively thick and are fixed with bolts, and the bolts here can also be connected to an external power supply together with wires.

[0051] In this embodiment, in order to better arrange the wires connected to the bolts, the first clamping plate 1 is provided with a first cover plate 11, and a first wire groove 12 is provided between the first cover plate 11 and the first clamping plate 1; the second clamping plate 2 is provided with a second cover plate 21, and a second wire groove 22 is provided between the second cover plate 21 and the second clamping plate 2. The wires can be hidden in the first cover plate 11 or the second cover plate 21 and arranged through the first wire groove 12 or the second wire groove 22 respectively. Example

[0052] See Figure 3 , Figure 4 , Figure 5 , Figure 6 The utility model provides an electroplating hanger. The electroplating clip used in the figure is the electroplating clip in Example 2, and also includes: a rectangular outer frame 7, and the electroplating clip is located on both sides of the rectangular outer frame 7.

[0053] Binding posts 8 are provided on the front and back sides of the four corners of the rectangular outer frame 7. One end of the binding post 8 is electrically connected to the first conductive clamping post 4 or the second conductive clamping post 5 through a wire, and the other end is connected to an external power supply, so that the electroplating rack can be double-sided electroplated after entering the electroplating bath.

[0054] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
