Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating technology, specifically to an electroplated flower basket and electroplating equipment. Background Technology
[0002] In recent years, due to the rapid development of the photovoltaic industry, the industrial-scale manufacturing technology of solar cells has become increasingly diversified, and the manufacturing cost has also decreased. Currently, the photovoltaic electrode manufacturing process uses screen printing of silver electrodes, which consumes a large amount of silver paste, and the cost of silver paste is relatively expensive. Electroplating copper technology, with its advantages of low cost and superior conductivity compared to silver paste, is considered the most promising photovoltaic electrode manufacturing process for achieving silver-free photovoltaics. However, the electroplating grid line process is currently limited by the tooling fixture structure and conduction method, preventing its widespread application.
[0003] Traditionally, the connection between the tooling fixture and the solar cell is achieved through precise alignment and clamping of the fixture and the solar cell using graphically pre-defined gripping points. This method, due to the need for pre-defined gripping points, forces the solar cell to sacrifice some of its light-receiving area, implying a slight reduction in efficiency. Furthermore, achieving proper connection requires extremely high precision between the fixture gripping points and the graphically pre-defined gripping points, placing stringent demands on automation and increasing automation costs, thus hindering capacity increases during mass production.

Preferably, the angle between the fixed clamping end and the movable clamping end is 0-45° to further reduce the breakage rate of the battery cells when the alignment assembly moves them.
[0020] In one optional implementation, the regularization component further includes:
[0021] A base plate is provided on one side of one of the pair of hangers, and the leveling plate is slidably mounted on the base plate;
[0022] The driving component is fixed to the base plate, and the driving end of the driving component is connected to the leveling plate.

[0055] Example 1
[0056] Traditionally, the connection between the tooling fixture and the solar cell is achieved through precise alignment and clamping of the fixture and the solar cell using graphically pre-defined gripping points. This method, due to the need for pre-defined gripping points, forces the solar cell to sacrifice some of its light-receiving area, implying a slight reduction in efficiency. Furthermore, achieving proper connection requires extremely high precision between the fixture gripping points and the graphically pre-defined gripping points, placing stringent demands on automation and increasing automation costs, thus hindering capacity increases during mass production.
[0057] Therefore, this embodiment provides an electroplated flower basket, including a pair of hanging racks 1, at least one fixed flower basket rod 2, at least one movable flower basket rod 3, and a regulating component.
[0058] In this embodiment, as Figures 1 to 3 As shown, a pair of hanging racks 1 are arranged in parallel relative to each other. A fixed basket rod 2 is fixedly connected between the pair of hanging racks 1. Several fixed clamping parts 4 are fixedly provided on the fixed basket rod 2. A movable basket rod 3 is movably connected between the pair of hanging racks 1. Several movable clamping parts 5 are fixedly provided on the fixed basket rod 2. The fixed clamping parts 4 and the movable clamping parts 5 are positioned one-to-one and are suitable for clamping the battery cell 6 to be plated. The fixed clamping parts 4 and the movable clamping parts 5 are configured to pierce the insulating layer on the surface of the battery cell 6 to be plated at one end.
[0059] Traditionally, the connection between the tooling fixture and the battery cell is achieved through precise alignment and clamping using pre-defined clamping points on the tooling fixture and the battery cell. This method results in reduced battery cell efficiency and requires high alignment accuracy. In this embodiment, by using a fixed clamping member 4 and a movable clamping member 5 adapted to directly pierce the insulating layer on the surface of the battery cell 6 to be plated, the fixed clamping member 4 and the movable clamping member 5 can be directly electrically connected to the battery cell 6 at the clamping position, without the need for precise alignment or pre-defined clamping points on the battery cell 6.
[0060] In the above structure, the number of fixed clamping members 4 and movable clamping members 5 is the same, and the adjacent fixed clamping members 4 and movable clamping members 5 are used to clamp a piece of battery cell 6 to be plated. That is, the positions of the fixed clamping members 4 and movable clamping members 5 correspond one-to-one and the two are suitable for clamping the piece of battery cell 6 to be plated.
[0061] In this embodiment, in order to enable the fixed clamping member 4 and the movable clamping member 5 to directly pierce the insulating layer on the surface of the battery cell 6 to be plated by abutting one end, the fixed clamping member 4 and the movable clamping member 5 are sharpened at the ends that abut against the battery cell 6.
[0062] In this embodiment, the straightening component includes a straightening plate 71, a base plate 72, and a driving component 73.
[0063] like Figure 1 As shown, a base plate 72 is disposed on one side of one of the two brackets 1, and a leveling plate 71 is slidably disposed on the base plate 72; a driving member 73 is fixed to the base plate 72, and the driving end of the driving member 73 is connected to the leveling plate 71. The leveling plate 71 is configured to abut against the battery cell 6 to be plated and push the battery cell 6 to be plated to move to alignment; during the movement of the battery cell 6, the fixed clamping member 4 and the movable clamping member 5 are configured to scratch the insulating layer on the surface of the battery cell 6 to be plated.
[0064] In this embodiment, the hanging frame 1, the fixed flower basket rod 2, and the movable flower basket rod 3 all adopt existing structures. The fixed flower basket rod 2 is directly fixed to the hanging frame 1, and the fixed clamping member 4 is fixed to the fixed flower basket rod 2. Therefore, the positions of the fixed flower basket rod 2 and the fixed clamping member 4 do not change during use. The two ends of the movable flower basket rod 3 are inserted into the through holes opened on the hanging frame 1 to ensure that the movable flower basket rod 3 can move relative to the hanging frame 1. The movable clamping member 5 is fixed on the movable flower basket rod 3, so the movable clamping member 5 can move with the movable flower basket rod 3. At least one end of the movable flower basket rod 3 is provided with a limiting block 8, and an elastic member 9, such as a spring, is sleeved on the end of the movable flower basket rod 3. The elastic member 9 is located between the limiting block 8 and the hanging frame 1, and the elastic member 9 has an elastic force that pushes the movable clamping member to move in the direction of the fixed clamping member.
[0065] When it is necessary to place the battery cell 6 to be plated, move the movable basket rod 3 so that the movable clamping member 5 moves away from the fixed clamping member 4. After the battery cell 6 to be plated is placed, release the movable basket rod 3 so that the movable basket rod 3 moves closer to the fixed clamping member 4 under the action of the elastic member 9 and clamps the battery cell 6 to be plated together with the fixed clamping member 4.
[0066] During the process of placing the battery cells 6 to be plated, the edges of all the battery cells 6 to be plated will be misaligned. In order to align the battery cells 6 to be plated, a straightening component is provided in this embodiment.
[0067] During the alignment process, the driving component 73 drives the alignment plate 71 connected to it to slide on the base plate 72. The alignment plate 71 moves towards the solar cell 6 to be plated and pushes the solar cell 6 to be plated to move, as shown in the figure. Figure 1 As shown, the height of the leveling plate 71 is sufficient to cover all the edges of the battery cells 6 to be plated. Therefore, the leveling plates 71 on both sides of the battery cells 6 to be plated push the battery cells 6 to be plated at the same time until all the sides of the battery cells 6 to be plated are aligned. Then the drive unit 73 drives the leveling plate 71 connected to it to reset.
[0068] During the movement of the battery cell 6 to be plated, the sharpened ends of the fixed clamping member 4 and the movable clamping member 5 will further cut through the insulating layer on the surface of the battery cell 6 to be plated, thereby achieving further conductivity and ensuring the reliability of the conductivity between each clamping point and the battery cell 6 to be plated.
[0069] In this embodiment, the fixed clamping member 4 and the movable clamping member 5 are arranged on opposite sides of the battery sheet 6 to be plated along the thickness direction of the battery sheet 6. In order to achieve the regularization of the battery sheet 6 to be plated, two regularization plates 71 are arranged on opposite sides in the length or width direction of the battery sheet 6 to be plated, so as to be able to abut against the side of the battery sheet 6 to be plated.
[0070] In this embodiment, in order to reduce the breakage rate of the battery cell 6 when clamping it, the included angle between the end of the fixed clamping member 4 and the end of the movable clamping member 5 is 0-90°. Preferably, the included angle between the end of the fixed clamping member 4 and the end of the movable clamping member 5 is 0-45°, so as to further reduce the breakage rate of the battery cell 6 when the alignment component pushes it to move.
[0071] In this embodiment, as Figure 3 and Figure 4 In the structure shown, the sharpened end of the fixed clamping member 4 is pointed, and the sharpened end of the movable clamping member 5 is flat.
[0072] As an alternative, the sharpened end of the fixed clamping member 4 is flat, and the sharpened end of the movable clamping member 5 is also flat. When the sharpened ends of both the fixed clamping member 4 and the movable clamping member 5 are flat, the ends of the fixed clamping member 4 and the movable clamping member 5 are arranged to cross or align.
[0073] The electroplated flower basket provided in this embodiment is used as follows:
[0074] When placing the battery cell 6 to be plated, first move the movable basket rod 3 so that the movable clamping member 5 moves away from the fixed clamping member 4. After placing the battery cell 6, release the movable basket rod 3 so that it moves closer to the fixed clamping member 4 under the action of the elastic member 9 and clamps the battery cell 6 together with the fixed clamping member 4. The fixed clamping member 4 and the movable clamping member 5 are directly electrically connected to the battery cell 6 at the clamping position. During alignment, the driving member 73 drives the alignment plate 71 connected to it to slide on the base plate 72. The alignment plate 71 moves towards the battery cell 6 and pushes the battery cell 6 to move until all the sides of the battery cell 6 are aligned. Then, the driving member 73 drives the alignment plate 71 connected to it to reset. During the movement of the battery cell 6, the sharpened parts at the ends of the fixed clamping member 4 and the movable clamping member 5 will further scratch the insulating layer on the surface of the battery cell 6, achieving further conductivity and ensuring the reliability of the conductivity between each clamping point and the battery cell 6.
