[0047] Embodiment 1
[0048] The new energy industry represented by solar power generation is developing rapidly, and is developing at a faster and foreseeable speed. How to further reduce the manufacturing cost of solar cells has become an important issue in the industry, and the cost of solar cell electrodes is the largest proportion of the entire non-silicon cost.
[0049] The current preparation of solar cell electrodes adopts the method of screen printing silver paste, and the price of screen printing equipment including silver paste is very high and difficult to reduce, so the industry is considering replacing screen printing silver paste with electroplating copper. The photovoltaic industry has a large capacity and high process requirements, so how to quickly and high-quality electroplate metal electrodes such as copper and tin is a very difficult technical problem.
[0050] And in view of the characteristics of single-sided electroplating required by the back contact cell structure, the present embodiment designs a set of electroplating tooling, including a hanger 1, a separation strip 2, a main frame 3, a fixed basket rod 5, a movable basket rod 6, a fixed clamping piece 7 and an elastic clamping piece 8.
[0051] In the present embodiment, as shown in Figure 1 and Figure 2 , the hanger 1 is a pair, and the pair of hangers 1 are arranged in parallel, the fixed basket rod 5 is fixedly connected between the pair of hangers 1, and a plurality of fixed clamping pieces 7 are fixedly arranged on the fixed basket rod 5; the movable basket rod 6 is movably connected between the pair of hangers 1, a plurality of elastic clamping pieces 8 are fixedly arranged on the fixed basket rod 5, and the fixed clamping pieces 7 and the elastic clamping pieces 8 are distributed in pairs and suitable for clamping two pieces of to-be-plated BC cell pieces 4 therebetween.
[0052] The hanger 1, the fixed flower basket rod 5, the movable flower basket rod 6, the fixed clamping piece 7 and the elastic clamping piece 8 used in the embodiment all adopt the existing structure, and the isolation strip 2 and the main frame 3 are adapted to the existing structure.
[0053] Figure 1 A front view of the electroplating tool provided in Embodiment 1, Figure 2 A top view of the electroplating tool provided in Embodiment 1. As Figure 1 And Figure 2 In the embodiment shown in the figure, the number of hangers 1 is two, and the two hangers 1 are both used for connecting electrodes. The fixed flower basket rod 5 is fixedly connected at both ends of the hanger 1, and the fixed flower basket rod 5 can be connected to the hanger 1 by plug-in connection, bolt connection or other connection methods. The movable flower basket rod 6 is movably connected between the pair of hangers 1. The movable flower basket rod 6 can move relative to the hanger 1, or more accurately, the movable flower basket rod 6 can move relative to the fixed flower basket rod 5. Specifically, the movable flower basket rod 6 can be inserted into the hanger 1 by plug-in connection, so that the movable flower basket rod 6 can move relative to the hanger 1. Further, a cylindrical spring is sleeved on the end of the movable flower basket rod 6, one end of the cylindrical spring abuts against the surface of the hanger 1, and the other end of the cylindrical spring abuts against the limiting protrusion on the movable flower basket rod 6, so that the movable flower basket rod 6 is kept in the working position corresponding to the fixed flower basket rod 5 by the elastic force of the cylindrical spring.
[0054] The fixed flower basket rod 5 is fixedly provided with a plurality of fixed clamping pieces 7, and the movable flower basket rod 6 is fixedly provided with a plurality of elastic clamping pieces 8. The fixed clamping pieces 7 and the elastic clamping pieces 8 are distributed in pairs and are adapted to clamp two pieces of BC battery pieces 4 therebetween. As described above, the end of the movable flower basket rod 6 is sleeved with a cylindrical spring, and the movable flower basket rod 6 is kept in the working position corresponding to the fixed flower basket rod 5 by the elastic force of the cylindrical spring. The working position refers to that the two pieces of BC battery pieces 4 are clamped between the fixed clamping pieces 7 and the elastic clamping pieces 8. When the two pieces of BC battery pieces 4 are placed, the movable flower basket rod 6 is moved, the elastic clamping pieces 8 on the movable flower basket rod 6 are moved, the distance between the fixed clamping pieces 7 and the elastic clamping pieces 8 is increased, and then the two pieces of BC battery pieces 4 are placed. After the two pieces of BC battery pieces 4 are placed, the movable flower basket rod 6 is loosened, and the movable flower basket rod 6 is reset under the action of the cylindrical spring, so that the two pieces of BC battery pieces 4 are clamped by the fixed clamping pieces 7 and the elastic clamping pieces 8. Therefore, the working position is the position where the two pieces of BC battery pieces 4 are clamped by the fixed clamping pieces 7 and the elastic clamping pieces 8.
[0055] The working processes of the fixed flower basket rod 5, the movable flower basket rod 6, the fixed clamping piece 7 and the elastic clamping piece 8 are all existing technologies. In order to facilitate the understanding of the technical scheme, the working processes of the fixed flower basket rod 5, the movable flower basket rod 6, the fixed clamping piece 7 and the elastic clamping piece 8 are described in detail.
[0056] From the feature of the back contact cell structure, the BC cell (back contact cell) only needs to be plated on one side. Therefore, in the embodiment, a plurality of isolation strips 2 are arranged, and in the plating state, one isolation strip 2 is clamped between any pair of fixed clamping pieces 7 and elastic clamping pieces 8, and the isolation strip 2 is between two BC cell pieces 4 to be plated.
[0057] It can be understood that in the embodiment, the fixed clamping pieces 7 and the elastic clamping pieces 8 clamp the two BC cell pieces 4 to be plated, and an isolation strip 2 made of insulating material is clamped between the two BC cell pieces 4 to be plated. Therefore, when the two BC cell pieces 4 to be plated are plated, since the isolation strip 2 made of insulating material is clamped between the two BC cell pieces 4 to be plated, only the opposite side of the two BC cell pieces 4 to be plated is plated, and the side on the two sides of the isolation strip 2 is not plated.
[0058] Figure 3 The structure of the isolation strip 2 provided in the embodiment 1 is shown in the figure. As shown in the figure, all the isolation strips 2 are fixed to a main frame 3, and all the isolation strips 2 are arranged in the same direction relative to the main frame 3. Figure 3
[0059] In order to improve the efficiency of placing the isolation strip 2 when plating the BC cell piece 4 to be plated, in the embodiment, all the isolation strips 2 are fixed to a main frame 3, and all the isolation strips 2 are arranged in the same direction relative to the main frame 3. Therefore, when the isolation strip 2 needs to be placed, only the external power device needs to clamp the main frame 3, and then all the isolation strips 2 are placed in place at the same time.
[0060] The above structure, in the process of assembling the BC cell piece 4 to be plated, first pushes the movable basket rod 6, so that the elastic clamping piece 8 on the movable basket rod 6 moves, and then the distance between the fixed clamping piece 7 and the elastic clamping piece 8 increases; then the first layer of BC cell pieces 4 to be plated between each group of fixed clamping pieces 7 and elastic clamping pieces 8 is placed in place, and then the isolation strip 2 is inserted into the first layer of BC cell pieces 4 to be plated by the power device. The position of the isolation strip 2 is on the side of the first layer of BC cell pieces 4 to be plated which is close to the second layer of BC cell pieces 4 to be plated, and then the second layer of BC cell pieces 4 to be plated is placed. The two layers of BC cell pieces 4 to be plated are placed back to back, the isolation strip 2 is between the two layers of BC cell pieces 4 to be plated, and the isolation strip 2 and the two BC cell pieces 4 to be plated are clamped between the fixed clamping piece 7 and the elastic clamping piece 8.
[0061] In the embodiment shown in the figure, the main frame 3 is a rectangular frame, and a plurality of isolation strips 2 are fixed to the two sides of the main frame 3 along the length direction of the main frame 3. Figure 3
[0062] In the embodiment, the BC battery piece 4 to be plated is rectangular, and as shown in Figure 2 the fixing and clamping piece 7 and the elastic clamping piece 8 are arranged in the width direction of the BC battery piece 4 to be plated, and the two groups of fixing and clamping pieces 7 and elastic clamping pieces 8 clamp the two side edge portions of the BC battery piece 4 to be plated respectively. Therefore, the main frame 3 is provided in the form of a rectangular frame, and the plurality of isolation strips 2 are fixed on the two sides of the main frame 3 in two rows along the length direction of the main frame 3. It can be understood that the two rows of isolation strips 2 are adapted to the two groups of fixing and clamping pieces 7 and elastic clamping pieces 8 of the two side edge portions of the BC battery piece 4 to be plated respectively.
[0063] As shown in Figure 3 , the number of isolation strips 2 in the two rows along the length direction of the main frame 3 is equal, and the positions of the two rows of isolation strips 2 correspond to each other, that is, the isolation strips 2 at the same position in each row are located on the same plane. This design can ensure that when the isolation strips 2 are inserted into the first layer of BC battery pieces 4 to be plated by the power device, the isolation strips 2 at the same position in each row can be accurately located on the same side of the same BC battery piece 4 to be plated. For example, as shown in Figure 3 , the upper and lower isolation strips 2 at the left end of the main frame 3 are at the same position in each row, and the two isolation strips 2 are located on the same plane. For another example, the upper and lower isolation strips 2 at the second position of the left end of the main frame 3 are also at the same position in each row, and the two isolation strips 2 are also located on the same plane.
[0064] The electroplating tool provided in the embodiment has the following use process:
[0065] First, the movable basket rod 6 is pushed to move the elastic clamping piece 8 on the movable basket rod 6. Then, the first layer of BC battery pieces 4 to be plated between each group of fixing and clamping pieces 7 and elastic clamping pieces 8 are placed in position. Then, the isolation strip 2 is inserted into the first layer of BC battery pieces 4 to be plated by the power device, and the position of the isolation strip 2 is on the side of the first layer of BC battery pieces 4 to be plated close to the second layer of BC battery pieces 4 to be plated. Then, the second layer of BC battery pieces 4 to be plated is placed, and the two layers of BC battery pieces 4 to be plated are placed back to back, the isolation strip 2 is between the two layers of BC battery pieces 4 to be plated, and the isolation strip 2 and the two BC battery pieces 4 to be plated are clamped between the fixing and clamping piece 7 and the elastic clamping piece 8. Finally, power is supplied to electroplate one side of the BC battery piece 4 to be plated.
[0066] Embodiment 2
[0067] The electroplating tool provided in the embodiment has the following use process:
[0068] In the embodiment, Figure 4 is a structural schematic view of the isolation strip 2 provided in the embodiment 2. As shown in Figure 4As shown, all isolation strips 2 are fixed with the fixed basket rod 5, and the isolation strips 2 are on the same side of the fixed basket rod 5 as the fixed clamping pieces 7; the isolation strips 2 are arranged on the side of the fixed clamping pieces 7 facing the elastic clamping pieces 8 adapted thereto.
[0069] As described in Embodiment 1, the fixed basket rod 5 is fixed with a plurality of fixed clamping pieces 7, and the movable basket rod 6 is fixed with a plurality of elastic clamping pieces 8; the fixed clamping pieces 7 and the elastic clamping pieces 8 are distributed in pairs and are adapted to clamp two pieces of BC battery pieces 4 therebetween. The movable basket rod 6 is sleeved with a columnar spring at the end, and the movable basket rod 6 is kept in the working position corresponding to the fixed basket rod 5 by the elastic force of the columnar spring. The working position refers to that the two pieces of BC battery pieces 4 are clamped between the fixed clamping pieces 7 and the elastic clamping pieces 8. When placing the two pieces of BC battery pieces 4, the movable basket rod 6 is moved to make the elastic clamping pieces 8 on the movable basket rod 6 move, so that the distance between the fixed clamping pieces 7 and the elastic clamping pieces 8 is increased. After the two pieces of BC battery pieces 4 are placed, the movable basket rod 6 is loosened, and the movable basket rod 6 is reset under the action of the columnar spring, so that the fixed clamping pieces 7 and the elastic clamping pieces 8 clamp the two pieces of BC battery pieces 4.
[0070] Therefore, in the embodiment, all isolation strips 2 are fixed with the fixed basket rod 5, and the isolation strips 2 are on the same side of the fixed basket rod 5 as the fixed clamping pieces 7; further, the isolation strips 2 are arranged on the side of the fixed clamping pieces 7 facing the elastic clamping pieces 8 adapted thereto. When placing the first layer of BC battery pieces 4 to be plated, the fixed clamping pieces 7 on the fixed basket rod 5 need to be pried open by the isolation strips 2 to place the first layer of BC battery pieces 4 to be plated, and then the second layer of BC battery pieces 4 to be plated is placed back to back. After the placement is completed, the movable basket rod 6 is reset under the action of the columnar spring, clamping the two pieces of BC battery pieces 4 and the isolation strips 2.
[0071] In the embodiment, as described above, when placing the first layer of BC battery pieces 4 to be plated, the fixed clamping pieces 7 on the fixed basket rod 5 need to be pried open by the isolation strips 2 to place the first layer of BC battery pieces 4 to be plated, so the isolation strips 2 are configured to elastically deform under the action of external force. Preferably, the isolation strips 2 are made of a material with a certain flexibility or elastic modulus.
[0072] In the embodiment, the distance between the isolation strips 2 and the fixed clamping pieces 7 on one side thereof is less than the thickness of the BC battery pieces 4 to be plated.
[0073] Embodiment 3
[0074] The embodiment provides a plating tool, which is different from the plating tool provided in Embodiment 1 in that:
[0075] In the embodiment, Figure 5This is a schematic diagram of the structure of the isolation strip 2 provided in embodiment 3. Figure 5 As shown, all the isolation strips 2 are fixed to the movable basket rod 6, and the isolation strips 2 and the elastic clamping pieces are on the same side of the movable basket rod 6; the isolation strips 2 are located on the side of the elastic clamping pieces 8 facing the elastic clamping pieces that are adapted to them.
[0076] Similarly, in this embodiment, during the assembly process of the BC battery cells 4 to be plated, the electroplating fixture first pushes the movable basket rod 6, causing the elastic clamping piece 8 on the movable basket rod 6 to move, thereby increasing the distance between the elastic clamping piece 8, the separator strip 2 and the fixed clamping piece 7. Then, the first layer of BC battery cells 4 to be plated is placed between the fixed clamping piece 7 and the separator strip 2. Then, the second layer of BC battery cells 4 to be plated is placed between the separator strip 2 and the elastic clamping piece 8. After the two BC battery cells 4 to be plated are placed, the movable basket rod 6 is released, and the movable basket rod 6 is reset under the action of the columnar spring, so that the fixed clamping piece 7 and the elastic clamping piece 8 clamp the two BC battery cells 4 to be plated.
[0077] Among them, the distance between the isolation strip 2 and the elastic clamping piece 8 on one side is less than the thickness of the BC battery cell 4 to be plated.

[0079] This embodiment provides an electroplating fixture, which differs from the electroplating fixture provided in Embodiment 1 in that:
[0080] In this embodiment, Figure 6 This is a schematic diagram of the structure of the isolation strip provided in Embodiment 4. Figure 6 As shown, the isolation strip 2 includes a fixed part that is fixed to the fixed basket pole 5, and a movable part that is flipped and connected to the fixed part; the movable part is configured to flip relative to the fixed part at the connection point with the fixed part under the action of external force, and to return to its original position after the external force is lost.
[0081] Specifically, the movable part is flipped and connected to the fixed part, and the movable part is configured to flip relative to the fixed part at the connection point under external force, and to return to its original position after the external force is removed. When placing the first layer of BC solar cells to be plated 4, it is only necessary to move the movable part towards... Figure 6 Move the lever to the right, and then place the first layer of BC battery cells 4 to be plated between the separator strip 2 and the fixed clamping piece 7. Then place the second layer of BC battery cells 4 to be plated between the separator strip 2 and the elastic clamping piece 8. After placing the two BC battery cells 4 to be plated, release the movable basket rod 6. The movable basket rod 6 will return to its original position under the action of the column spring, so that the fixed clamping piece 7 and the elastic clamping piece 8 clamp the two BC battery cells 4 to be plated.
[0082] The connecting component between the fixed part and the movable part can be made of an elastic material, so that the movable part can deflect relative to the fixed part and can return to its original position after the external force is removed.
[0083] In this embodiment, the isolation strip 2 is made of shape memory alloy, so it can automatically reset itself after the movable part is flipped over.
[0084] Example 5
[0085] This embodiment provides an electroplating fixture, which differs from the electroplating fixture provided in Embodiment 1 in that:
[0086] In this embodiment, Figure 7 This is a schematic diagram of the structure of the isolation strip 2 provided in embodiment 5. Figure 7 As shown, the main frame 3 is connected to the fixed basket pole 5 and is configured to rotate around the fixed basket pole 5 or the movable basket pole 6.
[0087] Specifically, the main frame 3 can be fitted around the fixed basket pole 5. When it is necessary to place the first layer of BC battery cells to be plated 4, the separator strip 2 is rotated to... Figure 7 The solid line indicates the location. After placing the first layer of BC solar cells 4 to be plated, rotate the separator strip 2 to... Figure 7 The position is indicated by the dotted line.
