Description

Technical Field

[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 widely 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

[0038] Example 1

[0039] See Figure 1 , Figure 4 , Figure 5 The utility model provides an electroplating fixture, comprising:

[0040] A first clamping plate 1, wherein the first clamping plate 1 is provided with a plurality of first conductive clamping columns 4 at intervals;

[0041] and a second clamping plate 2, on which a plurality of second conductive clamping columns 5 are arranged at intervals;

[0042] and a U-shaped elastic member 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 the U-shaped elastic member 3 .

[0043] The electroplating fixture is mainly composed of three parts, a U-shaped elastic member 3 made of spring steel in the middle, and a first clamping plate 1 and a second clamping plate 2 at both ends of the U-shaped elastic member 3, and an opening of the U-shaped elastic member 3 facing away from the clamping ends of the first conductive clamping column 4 and the second conductive clamping column 5. Since the U-shaped elastic member 3 is made of spring steel, in order to reduce the weight of the entire electroplating fixture, the U-shaped elastic member 3 is mainly light and thin.

[0044] The first conductive clamping column 4 and the second conductive clamping column 5 are made of metal and can conduct electricity, and have a relatively thin diameter, so as to be suitable for clamping and electroplating the sheet 100 without crushing the sheet 100. When in use, force is applied to the first clamping plate 1 and the second clamping plate 2 near the opening of the U-shaped elastic member 3, so that the U-shaped elastic member 3 is compressed and deformed, thereby driving the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to separate, thereby feeding or removing the sheet 100. After releasing the first clamping plate 1 and the second clamping plate 2, the U-shaped elastic member 3 returns to its original shape, and can drive the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to clamp the sheet 100.

[0045] In this embodiment, the first conductive clamping column 4 and the first clamping plate 1, and the second conductive clamping column 5 and the second clamping plate 2 are bolted. Since the U-shaped elastic member 3 made of spring steel is relatively thin, the bolt connection referred to here can be but is not limited to being fastened with a non-conductive PVC nut.

[0046] In this embodiment, the U-shaped elastic member 3 is connected with a receiving column 6, the receiving column 6 is located between the first conductive clamping column 4 and the second conductive clamping column 5, and the receiving column 6 is provided with a first bayonet 61. The first bayonet 61 is suitable for placing the edge of the sheet 100. For easy installation, the side of the receiving column 6 close to the U-shaped elastic member 3 can be connected to the closed end of the U-shaped elastic member 3 by bolt fixing.

[0047] In this embodiment, in order to make electroplating more accurate and prevent leakage, non-conductive coatings are coated on the non-clamping points of the first clamping plate 1, the second clamping plate 2, and the first conductive clamping column 4 and the second conductive clamping column 5. The non-conductive coating can be, but is not limited to, nano-ceramic coatings, polymer films, hard carbon nitride films, and the like.

[0048] Example 2

[0049] See Figure 2 , Figure 4 , Figure 5 The utility model provides an electroplating fixture, comprising:

[0050] A first clamping plate 1, wherein the first clamping plate 1 is provided with a plurality of first conductive clamping columns 4 at intervals;

[0051] and a second clamping plate 2, on which a plurality of second conductive clamping columns 5 are arranged at intervals;

[0052] and a U-shaped elastic member 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 the U-shaped elastic member 3 .

[0053] The electroplating fixture is mainly composed of three parts, a U-shaped elastic member 3 made of PVC material in the middle, and a first clamping plate 1 and a second clamping plate 2 at both ends of the U-shaped elastic member 3, and the opening of the U-shaped elastic member 3 faces away from the clamping ends of the first conductive clamping column 4 and the second conductive clamping column 5. Since the U-shaped elastic member 3 is made of PVC material, which is relatively light, the thickness of the U-shaped elastic member 3 can be increased to ensure sufficient elasticity.

[0054] The first conductive clamping column 4 and the second conductive clamping column 5 are made of metal and can conduct electricity, and have a relatively thin diameter, so as to be suitable for clamping and electroplating the sheet 100 without crushing the sheet 100. When in use, force is applied to the first clamping plate 1 and the second clamping plate 2 near the opening of the U-shaped elastic member 3, so that the U-shaped elastic member 3 is compressed and deformed, thereby driving the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to separate, thereby feeding or removing the sheet 100. After releasing the first clamping plate 1 and the second clamping plate 2, the U-shaped elastic member 3 returns to its original shape, and can drive the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to clamp the sheet 100.

[0055] In this embodiment, the first conductive clamping column 4 and the first clamping plate 1 are connected by bolts, and the second conductive clamping column 5 and the second clamping plate 2 are connected by bolts. Since the U-shaped elastic member 3 made of PVC is relatively thick, the bolt connection in this embodiment can be fastened without using nuts.

[0056] In this embodiment, the U-shaped elastic member 3 is connected with a receiving column 6, the receiving column 6 is located between the first conductive clamping column 4 and the second conductive clamping column 5, and the receiving column 6 is provided with a first bayonet 61. The first bayonet 61 is suitable for placing the edge of the sheet 100. For easy installation, the side of the receiving column 6 close to the U-shaped elastic member 3 can be connected to the closed end of the U-shaped elastic member 3 by bolt fixing.

[0057] In this embodiment, in order to make electroplating more accurate and prevent leakage, non-conductive coatings are coated on the non-clamping points of the first clamping plate 1, the second clamping plate 2, and the first conductive clamping column 4 and the second conductive clamping column 5. The non-conductive coating can be, but is not limited to, nano-ceramic coatings, polymer films, hard carbon nitride films, and the like.

[0061] and a second clamping plate 2, on which a plurality of second conductive clamping columns 5 are arranged at intervals;

[0062] and a U-shaped elastic member 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 the U-shaped elastic member 3 .

[0063] The electroplating fixture is mainly composed of three parts, a U-shaped elastic member 3 made of rubber in the middle, and a first clamping plate 1 and a second clamping plate 2 at both ends of the U-shaped elastic member 3, and an opening of the U-shaped elastic member 3 facing away from the clamping ends of the first conductive clamping column 4 and the second conductive clamping column 5. Since the U-shaped elastic member 3 is made of rubber, which is heavier than PVC and spring steel, the U-shaped elastic member 3 also needs a certain thickness to ensure sufficient elasticity.

[0064] The first conductive clamping column 4 and the second conductive clamping column 5 are made of metal and can conduct electricity, and have a relatively thin diameter, so as to be suitable for clamping and electroplating the sheet 100 without crushing the sheet 100. When in use, force is applied to the first clamping plate 1 and the second clamping plate 2 near the opening of the U-shaped elastic member 3, so that the U-shaped elastic member 3 is compressed and deformed, thereby driving the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to separate, thereby feeding or removing the sheet 100. After releasing the first clamping plate 1 and the second clamping plate 2, the U-shaped elastic member 3 returns to its original shape, and can drive the conductive ends of the first conductive clamping column 4 and the second conductive clamping column 5 to clamp the sheet 100.

[0065] In this embodiment, the first conductive clamping column 4 and the first clamping plate 1, and the second conductive clamping column 5 and the second clamping plate 2 are bolted. Since the thickness of the U-shaped elastic member 3 made of rubber is generally average, the bolt connection in this embodiment can also be fastened with nuts.

[0066] In this embodiment, the U-shaped elastic member 3 is connected with a receiving column 6, the receiving column 6 is located between the first conductive clamping column 4 and the second conductive clamping column 5, and the receiving column 6 is provided with a first bayonet 61. The first bayonet 61 is suitable for placing the edge of the sheet 100. For easy installation, the closed end of the U-shaped elastic member 3 made of rubber is thicker and can be directly connected to the receiving column 6 close to the side of the U-shaped elastic member 3.

[0067] In this embodiment, in order to make electroplating more accurate and prevent leakage, non-conductive coatings are coated on the non-clamping points of the first clamping plate 1, the second clamping plate 2, and the first conductive clamping column 4 and the second conductive clamping column 5. The non-conductive coating can be, but is not limited to, nano-ceramic coatings, polymer films, hard carbon nitride films, and the like.

The electrical connection between the first conductive clamping column 4 and the second conductive clamping column 5 is considered as the prior art, and will not be elaborated in detail here.

[0070] The outer frame 7 is provided with second clips 8 at intervals. The second clips 8 can be made of, but are not limited to, PVC material. The second clips 8 are suitable for clamping one long side of the sheet.

[0071] When electroplating a sheet material 100 such as a battery cell to be electroplated, one only needs to wait for the first conductive clamping column 4 and the second conductive clamping column 5 of the electroplating fixture to open, insert the second clamping hole 8 from the upper side, and then close the first conductive clamping column 4 and the second conductive clamping column 5 of the electroplating fixture to energize the clamping points for electroplating, which is convenient and quick.
