Description

Technical Field

[0001] This invention relates to the field of battery cell processing technology, and in particular to a battery cell electroplating equipment and electroplating method. Background Technology

[0002] During the production of solar cells, electroplating, also known as electrochemical deposition, is required. This process involves depositing metal particles from a chemical solution onto the solar cell under the influence of an applied electric field, thereby improving the cell's conductivity and oxidation resistance. Existing electroplating equipment mostly uses a single-cell rack plating method. This method involves clamping the solar cell with a fixture and hanging it vertically in the plating tank. However, because vertical plating requires the use of fixtures to hold the solar cell, the breakage rate is relatively high. Furthermore, the uniformity of vertical plating is poor, necessitating a reduction in deposition rate to improve uniformity. Therefore, this method results in lower single-machine capacity and lower production speed. Summary of the Invention

[0013] Preferably, the first electroplating tank is provided with a plurality of first electroplating pools, and a first vertical wall is formed between two adjacent first electroplating pools. The edge of the lower surface of the battery cell abuts against the first vertical wall. A first nozzle is provided in the first electroplating pool. The first nozzle is used to spray electroplating liquid onto the lower surface of the battery cell. The height of the first vertical wall is higher than the height of the first nozzle.

[0014] The second electroplating tank is provided with a plurality of second electroplating pools, and a second vertical wall is formed between two adjacent second electroplating pools. The edge of the lower surface of the battery cell abuts against the second vertical wall. The second electroplating pool is provided with a second nozzle, which is used to spray electroplating liquid onto the lower surface of the battery cell. The height of the second vertical wall is higher than the height of the second nozzle.

[0015] Preferably, the transfer assembly further includes a moving beam, a guide rail, and a drive motor. Multiple moving frames are disposed on the moving beam, the moving beam is adjustablely positioned on the guide rail, and the drive motor can drive the guide rail to move along the moving beam.

[0016] Preferably, the first conveyor belt is provided with a straightening structure on both sides, which can be attached to both sides of the battery cell.

[0017] Preferably, both the first electroplating tank and the second electroplating tank are provided with multiple tanks.

[0018] Preferably, the second conveyor belt includes an upper roller and a lower roller, which are arranged along the height direction. The lower surface of the battery cell abuts against the lower roller, and the upper surface of the battery cell abuts against the upper roller. The upper roller and the lower roller can rotate in opposite directions to drive the battery cell to move.

[0019] The solar cell electroplating method, using the aforementioned solar cell electroplating equipment, includes the following steps:

[0020] S1. Place the battery cell on the first conveyor belt and transport it above the lifting device, then use the lifting device to lift the battery cell to the removal position;

[0021] S2. Using the suction cup on the moving frame, the battery cell at the removal position is adsorbed and moved into the first electroplating tank to electroplat the lower surface of the battery cell;

[0022] S3. Use the suction cup on the moving frame to attract and move the battery cell in the first electroplating tank to the second conveyor belt, and transport the battery cell to the flipping wheel;

[0027] The beneficial effects of this invention are as follows:

[0028] The battery cell electroplating equipment provided by this invention features a first conveyor belt. After the operator places the battery cell on the first conveyor belt, the first conveyor belt transports the battery cell to a lifting device. The lifting device then rises to raise the battery cell to a transfer position, facilitating the transfer component to move the battery cell to the first electroplating tank for electroplating. Since the rotating wheel is connected to the battery cell and the rotating shaft drives the rotating wheel to rotate, the rotating wheel can rotate the battery cell whose lower surface has been electroplated in the first electroplating tank 180 degrees, facilitating electroplating of the upper surface of the battery cell in the second electroplating tank. Because a second conveyor belt is provided between the first electroplating tank and the rotating wheel, the battery cell whose lower surface has been electroplated can be transported to the rotating wheel via the second conveyor belt, which is convenient and fast. Since the moving frame can move between the rotating wheel and the second electroplating tank, the battery cell can be moved to the second electroplating tank via the moving frame, eliminating the need for manual movement of the battery cell and improving work efficiency. Because the moving frame is equipped with suction cups, the moving frame moves the battery cell by adsorption, greatly protecting the battery cell and reducing the breakage rate.

[0029] Using this battery cell electroplating method, suction cups are used to adsorb and move the battery cells, effectively preventing damage to the battery cells during the electroplating process. At the same time, horizontal electroplating of the battery cells is completed in the first electroplating tank and the second electroplating tank respectively, and the battery cells are rotated 180 degrees by a flipping wheel, which greatly facilitates the electroplating of the upper and lower surfaces and greatly improves the uniformity of electroplating, thereby improving the product yield.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] like Figure 1 and Figure 2As shown, the present invention provides a battery cell electroplating device, which includes a first conveyor belt 1, a lifting device, a first electroplating tank 3, a flipping component 5, a second conveyor belt 4, a second electroplating tank 6, and a transfer component 7. The first conveyor belt 1 is used to transport the battery cells to the top of the lifting device. The lifting device can rise upward to lift the battery cells on the first conveyor belt 1 to the transfer position. The first electroplating tank 3 is used to electroplat the lower surface of the battery cells. In this embodiment, since a first conveyor belt 1 is provided, after the operator places the battery cell on the first conveyor belt 1, the first conveyor belt 1 can transport the battery cell to the top of the lifting device 1. The lifting device can rise upward to lift the battery cell to the transfer position, thereby facilitating the transfer component 7 to move the battery cell to the first electroplating tank 3 for electroplating. The first conveyor belt 1 consists of a conveyor motor, a drive roller and a belt, which is a common device in the art. In use, the operator places the battery cell on the belt and turns on the conveyor motor. The conveyor motor drives the drive roller to rotate, which in turn drives the belt to rotate, thereby transporting the battery cell. The width of the battery cell is greater than the width of the belt. When the battery cell is placed on the belt, both sides of the battery cell extend out of the belt.

[0046] The flipping assembly 5 includes a rotating shaft 51 and a flipping wheel 52 passing through the rotating shaft 51. The flipping wheel 52 can be detachably connected to the battery cell. The rotating shaft 51 can drive the flipping wheel 52 to rotate so that the battery cell on the flipping wheel 52 can rotate 180 degrees. The second conveyor belt 4 is disposed between the first electroplating tank 3 and the flipping wheel 52. The second conveyor belt 4 is used to transport the battery cell in the first electroplating tank 3 to the flipping wheel 52. In this embodiment, a rotating motor is connected to one end of the rotating shaft 51. The rotating motor drives the rotating shaft 51 to rotate. The rotating wheel 52 has a disc-shaped structure and is fixed on the rotating shaft 51 in a direction perpendicular to the axial direction. The rotating wheel 52 is provided with a connecting structure, which can be a slot. When the battery cells in the first electroplating tank 3 are transported to the rotating wheel 52 by the second conveyor belt 4, the battery cells will be inserted into the slot on the rotating wheel 52 under the transport of the second conveyor belt 4, thereby rotating 180 degrees under the drive of the rotating wheel 52, which facilitates the subsequent electroplating of the upper surface of the battery cells. This is convenient, quick, time-saving and labor-saving. The connecting structure on the rotating wheel 52 can also be other clamping structures or adsorption structures, as long as they can drive the battery cells to rotate. There is no limitation here.

[0047] The second electroplating tank 6 is used to electroplat the upper surface of the battery cell; the transfer assembly 7 includes multiple moving frames 71, each equipped with a suction cup that can adsorb the battery cell; the moving frames 71 can move the battery cell from the transfer position to the first electroplating tank 3 via the suction cup, and the moving frames 71 can also move the battery cell on the flipping wheel 52 to the second electroplating tank 6 via the suction cup. In this embodiment, the battery cell electroplating equipment is horizontally arranged with the first electroplating tank 3 and the second electroplating tank 6 along a straight line. After the lower surface of the battery cell is electroplated in the first electroplating tank 3, the flipping wheel 52 and the movement of the transfer assembly 7 can move the battery cell that has completed single-sided electroplating in the first electroplating tank 3 to the third conveyor belt behind the flipping wheel 52. The third conveyor belt will drive the battery cell to move above the second lifting device, and the second lifting device can lift the battery cell upward to the second transfer position. Then the second transfer assembly will move the battery cell to the second transfer position. The battery cells at the second transfer position are moved to the second electroplating tank 6 for electroplating of the upper surface. After electroplating is completed, the fourth conveyor belt transports the electroplated battery cells from the second electroplating tank 6 to a designated temporary storage platform, thereby forming a continuous electroplating production line and improving the efficiency of electroplating. Specifically, the structure and relative position of the third conveyor belt, the second lifting device, the second transfer component, the second electroplating tank 6, and the fourth conveyor belt are the same as the structure and relative position of the first conveyor belt 1, the lifting device, the transfer component 7, the first electroplating tank 3, and the second conveyor belt 4. Specifically, the first conveyor belt 1, the first electroplating tank 3, the second conveyor belt 4, the flipping component 5, the third conveyor belt, the second electroplating tank 6, and the fourth conveyor belt are arranged in a straight line. That is, the same battery cell moves along the first direction from one end of the first conveyor belt 1 to the other end of the second electroplating tank 6 on this battery cell electroplating equipment. The moving frame 71 can move from above the first conveyor belt 1 along the first direction to above the second electroplating tank 6. Therefore, the battery cell can be moved into the second electroplating tank 6 by the moving frame 71 without the need for manual movement of the battery cell, which improves work efficiency. Since the moving frame 71 is equipped with suction cups, which can be vacuum suction cups or Bernoulli suction cups, it can adsorb the battery cell. The moving frame 71 realizes the movement of the battery cell by adsorption of the suction cups, which greatly protects the battery cell and reduces the breakage rate.

[0048] Furthermore, the lifting device includes two sets of horizontally adjustable lifting components disposed below the first conveyor belt 1. These two sets of lifting components can move upwards to abut against the lower surfaces of both sides of the battery cell, thereby lifting the battery cell to the removal position. In this embodiment, both ends of the battery cell extend beyond the sides of the belt. The two sets of lifting components are disposed below the first conveyor belt 1 and can move upwards to abut against the two ends of the battery cell extending beyond the first conveyor belt 1, thereby lifting the battery cell upwards. The lifting device also includes a first driving cylinder and a second driving cylinder. The first driving cylinder drives the two sets of lifting components to move up and down, and the second driving cylinder is disposed between the two sets of lifting components. The second driving cylinder drives the two sets of lifting components to move away from or closer to each other, thereby changing the horizontal distance between the two sets of lifting components. After the first driving cylinder drives the two sets of lifting components to rise to the removal position, the battery cell is removed. Component 7 removes the battery cell from the transfer position. Then, the second drive cylinder drives the two lifting components to move away from each other, making the distance between the two lifting components greater than the width of the battery cell. This allows the battery cell to fall back to the bottom of the first conveyor belt 1 under the drive of the first drive cylinder, preventing interference and collision between the two lifting components and the battery cell on the first conveyor belt 1 below during the fall. Afterward, the second drive cylinder drives the two lifting components to move closer together in preparation for the next lift. This cycle repeats continuously, with the two lifting components sequentially lifting the battery cell conveyed by the first conveyor belt 1 to the transfer position, greatly improving the electroplating efficiency of the battery cell electroplating equipment.

[0049] Specifically, the lifting assembly includes a support frame and a limiting platform mounted on the support frame. The support frame can drive the limiting platform to move. The limiting platform is provided with a guide ramp and a bearing surface connected to the bottom of the guide ramp. The edge of the battery cell can slide along the guide ramp so that the lower surface of the battery cell abuts against the bearing surface. In this embodiment, the limiting platform is fixed to the top of the support frame, and both the first and second drive cylinders are connected to the support frame. The limiting platform is provided with a guide ramp and a bearing surface connected to the bottom of the guide ramp. When the support frame drives the limiting platform to rise, the limiting platform contacts the battery cell. The guide ramp allows the battery cell to slide down onto the bearing surface under its own weight. The bearing surface matches the shape of the battery cell, which can position and correct the battery cell, preventing the battery cell from deviating from its predetermined position and affecting subsequent electroplating, thus improving the electroplating yield. The above-described structure and limiting method of the limiting platform are common technical means in the art. The limiting platform can also use other methods to correct and position the battery cell, which are not limited here.

[0050] Furthermore, the first electroplating tank 3 is provided with multiple first electroplating pools, and a first vertical wall is formed between two adjacent first electroplating pools. The edge of the lower surface of the battery cell abuts against the first vertical wall. A first nozzle is provided in the first electroplating pool for spraying electroplating liquid onto the lower surface of the battery cell. The height of the first vertical wall is higher than the height of the first nozzle. The second electroplating tank 6 is provided with multiple second electroplating pools, and a second vertical wall is formed between two adjacent second electroplating pools. The edge of the lower surface of the battery cell abuts against the second vertical wall. A second nozzle is provided in the second electroplating pool for spraying electroplating liquid onto the lower surface of the battery cell. The height of the second vertical wall is higher than the height of the second nozzle. Specifically, during electroplating, the lower surface of the battery cell is placed on the first vertical wall formed between adjacent first electroplating tanks, and the lower surface of the battery cell is in contact with the upper surface of the first vertical wall. This encloses the first nozzle in the first electroplating tank within the battery cell and the first vertical wall. When the first nozzle sprays the electroplating solution onto the lower surface of the battery cell, the edge of the lower surface of the battery cell is pressed against the first vertical wall, thus preventing the electroplating solution from contaminating the side of the battery cell and causing leakage, thereby improving the electroplating yield of the battery cell. Similarly, the second electroplating tank 6 has the same structure as the first electroplating tank 3.

[0051] Furthermore, such as Figure 1 As shown, the transfer assembly 7 also includes a moving beam 73, a guide rail 74, and a drive motor. Multiple moving frames 71 are mounted on the moving beam 73, and the moving beam 73 is adjustablely positioned on the guide rail 74. The drive motor drives the guide rail 74 to move along the moving beam 73. In this embodiment, the guide rail 74 is positioned along a first direction. The drive motor drives the moving beam 73 to move along the guide rails 74 on both sides. Since multiple moving frames 71 are mounted on the moving beam 73, when the moving beam 73 moves along the guide rail 74, it can simultaneously move all the battery cells on the multiple moving frames 71, improving ease of operation and electroplating efficiency.

[0052] Furthermore, a alignment structure is provided on both sides of the first conveyor belt 1, which can abut against the sides of the battery cell. In this embodiment, the alignment structure is provided at the end of the first conveyor belt 1 closest to the worker loading the battery. The alignment structure can be alignment wheels on both sides of the first conveyor belt 1, with the distance between the two alignment wheels slightly greater than the width of the battery cell. After the worker places the battery cell on the first conveyor belt 1, the battery cell abuts against the two alignment wheels, thereby keeping the battery cell in a predetermined position on the first conveyor belt 1 and preventing the battery cell from shifting position and affecting the subsequent electroplating pass rate. Alignment wheels are a commonly used alignment structure in the art. In another embodiment, a guide slope structure can also be used to correct the position of the battery cell, which is not limited here.

[0053] Furthermore, multiple first electroplating tanks 3 and multiple second electroplating tanks 6 are provided. In this embodiment, the arrangement of multiple first electroplating tanks 3 and multiple second electroplating tanks 6 can meet the simultaneous electroplating requirements of multiple batches of battery cells, further improving electroplating efficiency.

[0054] Furthermore, the second conveyor belt 4 includes an upper roller and a lower roller, which are arranged along the height direction. The lower surface of the battery cell abuts against the lower roller, and the upper surface of the battery cell abuts against the upper roller. The upper and lower rollers can rotate in opposite directions to drive the battery cell to move. In this embodiment, multiple sets of upper rollers and multiple sets of lower rollers are arranged in a one-to-one correspondence. After the lower surface of the battery cell is electroplated in the first electroplating tank 3, the removal component 7 takes out the battery cell from the first electroplating tank 3 and places it between the upper and lower rollers. The upper and lower rollers rotate in opposite directions, thereby driving the battery cell to move. The upper and lower rollers can clamp the battery cell between them and move it, avoiding the battery cell from shifting during movement, and further ensuring the product yield.

[0055] This embodiment also provides a method for electroplating solar cells, using the aforementioned solar cell electroplating equipment, including the following steps:

[0056] S1. Place the battery cell on the first conveyor belt 1 and transport it above the lifting device. Use the lifting device to lift the battery cell to the removal position. Specifically, the operator places the battery cell on the first conveyor belt 1 along its length and starts the equipment. The first conveyor belt 1 can automatically move the battery cell above the lifting device. Then the first conveyor belt 1 stops transporting, and the two sets of lifting components of the lifting device move upward to lift the battery cell from the first conveyor belt 1 to the removal position.

[0057] S2. Using the suction cup on the moving frame 71, the battery cell at the transfer position is adsorbed and moved into the first electroplating tank 3 for electroplating of the lower surface of the battery cell. Specifically, the moving frame 71 moves above the transfer position and aligns the suction cup with the battery cell below. Then, the moving frame 71 moves downward to adsorb the battery cell using the suction cup. Subsequently, the moving frame 71 places the battery cell in the first electroplating tank 3 and places multiple battery cells one by one in multiple first electroplating tanks, with the edge of the lower surface of the battery cell pressed against the first vertical wall. Then, the pressure cap structure above the first electroplating tank 3 presses downward against the battery cell, and the first nozzle in the first electroplating tank sprays electroplating liquid onto the lower surface of the battery cell, thereby electroplating the battery cell.

[0058] S3. Use the suction cup on the moving frame 71 to pick up the battery cells in the first electroplating tank 3 and move them onto the second conveyor belt 4, and then transport the battery cells to the flip wheel 52. Specifically, after the electroplating of the lower surface of the battery cells is completed, the pressure cap structure above the first electroplating tank 3 is automatically opened, and the moving frame 71 picks up all the battery cells in the first electroplating tank 3 through the suction cup and moves them onto the second conveyor belt 4. The second conveyor belt 4 transports the battery cells to the flip wheel 52.

[0059] S4. Connect the battery cell on the second conveyor belt 4 to the rotating wheel 52, rotate the shaft 51, and the shaft 51 drives the battery cell to rotate 180 degrees through the rotating wheel 52. Specifically, the rotating wheel 52 is provided with a connecting structure, which can be a slot. When the battery cell moves to the rotating wheel 52, the battery cell will be inserted into the slot on the rotating wheel 52 under the drive of the second conveyor belt 4, so that it will be rotated 180 degrees under the drive of the rotating wheel 52, which facilitates the subsequent electroplating of the upper surface of the battery cell.

[0060] S5. Using the suction cups on the moving frame 71, the battery cells on the flipping wheel 52 are adsorbed and moved into the second electroplating tank 6 for electroplating of the upper surface of the battery cells. Specifically, after the battery cells are flipped 180 degrees by the flipping wheel 52, the moving frame 71 moves the battery cells on the flipping wheel 52 into the second electroplating tank 6 through the suction cups, and places multiple battery cells one by one into multiple second electroplating tanks, with the edge of the lower surface of the battery cells pressed against the second vertical wall. Then, the pressure cap structure above the second electroplating tank 6 presses down on the battery cells, and the second nozzle in the second electroplating tank sprays electroplating liquid onto the lower surface of the battery cells, thereby electroplating the upper surface of the battery cells. After the electroplating of the upper surface of the battery cells is completed, the pressure cap structure above the second electroplating tank 6 automatically opens, and the moving frame 71 adsorbs all the battery cells in the second electroplating tank 6 through the suction cups and moves them to the designated storage position. At this point, the electroplating of the battery cells is completed.

[0061] Specifically, step S1, placing the battery cells on the first conveyor belt 1, includes: placing the battery cells into the buffer device 8 and using the buffer device 8 to place the battery cells onto the first conveyor belt 1. In this embodiment, a buffer device 8 is provided on the first conveyor belt 1 near the loading end of the worker. The buffer device 8 can be an automatic buffer basket machine commonly used in the art. Automatic buffer basket machines are prior art, and their specific structure and working principle can be found in the utility model patent application number CN202123005960.1. When the first conveyor belt 1 behind the buffer device 8 is full and the transfer component 7 has not yet removed the battery cells, the buffer device 8 will temporarily collect the excess battery cells and release them when there is a shortage of material ahead. This eliminates the need to wait during the idle time when the worker takes the next batch of battery cells, thereby ensuring the continuity of the electroplating operation, improving work efficiency, and increasing overall efficiency.
