Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production, and in particular, to an electroplating device and a photovoltaic production system. Background Art

[0002] During the production of photovoltaic cells, an electroplating device is required for electroplating treatment to form grid lines. Specifically, a conveying mechanism is used to drive the movement of the cells until the cells are transferred into the electroplating tank for electroplating treatment.

[0003] Currently, during electroplating, current is applied as soon as the first cell enters the electroplating tank. Since the current on the first cell suddenly increases, it is difficult to maintain a stable current, which easily causes virtual plating or incomplete grid lines on the first cell. In addition, when the last cell enters the electroplating tank for electroplating, process defects such as overplating or excessive plating may occur due to the excessive current flowing through it. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an electroplating device and a cell production system to address the problems that the first cell is prone to virtual plating or incomplete grid lines during electroplating, resulting in defective products, and the last cell has process defects such as overplating or excessive plating due to excessive current.

[0005] In a first aspect, an electroplating device includes:

[0006] A first conveying mechanism configured to convey cells into the electroplating tank;

[0007] A second conveying mechanism configured to place a conductive member on the first conveying mechanism, wherein the conductive member is located at the upstream end and / or downstream end of the cell and is spaced apart from the cell;

[0008] An energizing mechanism electrically connected to the cell and the conductive member.

[0009] In one embodiment, the first conveying mechanism includes a first roller group and a second roller group. Along the height direction of the electroplating device, the second roller group is located above the first roller group. Both the cell and the conductive member are located between the first roller group and the second roller group, and the space between the first roller group and the second roller group is configured to clamp and convey the cell.

[0010] In one embodiment, the second conveying mechanism includes a moving component and a grasping component. The moving component is configured to drive the grasping component to move, and the grasping component is configured to grasp and place the conductive member on the first conveying mechanism.

[0011] In one embodiment, the moving component includes a moving driver, a synchronous belt, and a synchronous shaft. The output end of the moving driver is connected to the synchronous shaft, the synchronous belt is wound around the synchronous shaft, and the synchronous belt is connected to the grasping component.

[0012] In one embodiment, the grasping component includes a lifting driver, a telescopic driver, and a fixture. The lifting driver is connected to the moving component, the output end of the lifting driver is connected to the telescopic driver, the output end of the telescopic driver is connected to the fixture, and the fixture is configured to grasp the conductive part.

[0013] In one embodiment, the lifting driver is configured to drive the telescopic driver to move up and down along a first direction, the telescopic driver is configured to drive the fixture to move telescopically along a second direction, and the second direction is configured to intersect the first direction.

[0014] In one embodiment, the second conveying mechanism further includes a limit inductor, which is electrically connected to the moving component. The limit inductor is configured to stop driving the moving component to move when it detects that the grasping component moves to a preset position.

[0015] In one embodiment, the electroplating device further includes a first inductor, which is electrically connected to the second conveying mechanism. The first inductor is configured to place the conductive part at the downstream end of the battery cell when it detects the battery cell.

[0016] In one embodiment, the electroplating device further includes a second inductor, which is electrically connected to the second conveying mechanism. The second inductor is configured to place the conductive part at the upstream end of the last battery cell when it does not detect the battery cell within a set time.

[0017] In a second aspect, the photovoltaic production system includes the electroplating device as described in the first aspect.

[0018] The second conveying mechanism of the above electroplating device places a conductive member at the downstream end of the cell, and after the conductive member is located in front of the first cell entering the electroplating tank, the power-on mechanism simultaneously powers on the first cell and the conductive member. The conductive member can provide more electron flow paths, can be used as an additional electrode to improve current transmission, helps to stabilize the current on the first cell, enables the current to flow more evenly through the surface of the first cell, and thus can reduce the virtual plating or incomplete grid lines of the grid lines. When the first conveying mechanism conveys the last cell into the electroplating tank, the second conveying mechanism places a conductive member at the upstream end close to the last cell. The conductive member can absorb part of the current to share the current on the last cell and reduce the current density of the current flowing through its surface, thereby reducing the problem of over-plating or excessive plating of the last cell.

Detailed Embodiments

[0022] To make the above objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be given with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0023] Please refer to Figure 1 , an embodiment of the present application provides a photovoltaic production system 100, and the photovoltaic production system 100 includes a first cleaning tank body 2, an electroplating tank body 4, a second cleaning tank body 3, and an electroplating device. Along Figure 1In the X direction shown, the battery wafers 5 after being washed with water in the first cleaning tank 2 are transported to the electroplating device one by one. The electroplating device is used to transport the battery wafers 5 into the electroplating tank 4 one by one for electroplating, and the electroplated battery wafers 5 are then transported to the second cleaning tank 3 for cleaning one by one. In the embodiment of the present application, the automatic operation of the electroplating device is controlled by a PCL (Programmable Logic Controller) control system.

[0024] The electroplating tank 4 has an electroplating bath for containing an electroplating solution, and the electroplating solution can be a liquid whose solute includes copper ions or tin ions.

[0025] Please refer to Figure 1 , in some embodiments, the electroplating device includes a first conveying mechanism 11, a second conveying mechanism 12 and a power-on mechanism. The first conveying mechanism 11 is configured to convey the battery wafers 5 into the electroplating bath; the second conveying mechanism 12 is configured to place a conductive member 6 on the first conveying mechanism 11. The conductive member 6 is located at the upstream end and / or downstream end of the battery wafer 5 and is spaced from the battery wafer 5. The power-on mechanism is electrically connected to the battery wafer 5 and the conductive member 6. It can be understood that the second conveying mechanism 12 of the electroplating device places the conductive member 6 at the downstream end of the battery wafer 5, so that the conductive member 6 is located in front of the first battery wafer 5 entering the electroplating bath. The power-on mechanism simultaneously powers on the first battery wafer 5 and the conductive member 6. The conductive member 6 can provide more electron flow paths, can be used as an additional electrode to improve current transmission, helps to stabilize the current on the first battery wafer 5, makes the current flow more evenly through the surface of the first battery wafer 5, and thus can reduce the virtual plating or incomplete grid lines on the first battery wafer 5. When the first conveying mechanism 11 conveys the last battery wafer 5 into the electroplating bath, the second conveying mechanism 12 places the conductive member 6 near the upstream end of the last battery wafer 5. The conductive member 6 can absorb part of the current to share the current on the last battery wafer 5 and reduce the current density of the current flowing through its surface, thereby reducing the problems of over-plating or excessive plating of the last battery wafer 5.

[0026] The embodiment of the present application does not limit the number of transported battery wafers 5. Exemplarily, the number of battery wafers 5 can be one, two, three, etc. It should be noted that the direction of the production line movement of the battery wafers 5 in the embodiment of the present application is Figure 1 the X direction shown. The upstream refers to the starting point of the production line, and the downstream refers to the end point of the production line. When there is one battery wafer 5, the upstream end and the downstream end of the battery wafer 5 refer to the back and the front of the battery wafer 5. When there are multiple battery wafers 5, the upstream end of the battery wafers 5 refers to the back of the last battery wafer 5, and the downstream end of the battery wafers 5 refers to the front of the first battery wafer 5.

[0027] In the embodiments of the present application, the conductive member 6 is a copper sheet or a tin sheet, etc. Optionally, there may be one or two conductive members 6, and the second conveying mechanism 12 may be one or more. One conductive member 6 can be successively placed in front of or behind the battery cell 5 by one second conveying mechanism 12. Or, two conductive members 6 can be respectively placed in front of and behind the battery cell 5 by two second conveying mechanisms 12.

[0028] In some embodiments, the energizing mechanism includes a power supply component, an anode component, and a cathode component that are electrically connected. The anode component is immersed in the plating solution in the plating tank and can charge the plating solution. The cathode component is electrically connected to the battery cell 5 and the conductive member 6 respectively. Exemplarily, the anode component can be a metal mesh or a metal plate. The cathode component includes a first conductive fixture and a second conductive fixture. The first conductive fixture is electrically connected to the battery cell 5, and the second conductive fixture is electrically connected to the conductive member 6. The second conductive fixture can be provided separately, or, please refer to Figure 2 , the second conductive fixture can be integrally provided with the fixture 1223 for clamping the conductive member 6 in the second conveying mechanism 12.

[0029] In the embodiments of the present application, the electroplating principle is as follows: The first conveying mechanism 11 conveys the battery cell 5 into the plating tank, immersing the battery cell 5 in the plating solution. The plating solution contains conductive metal ions to be plated, forming a plating circuit between the energizing mechanism, the battery cell 5, and the conductive member 6. The metal ions to be plated in the plating solution will move towards the plating surface of the battery cell 5 under the action of the electric field force. The metal ions to be plated will obtain electrons on the plating surface of the battery cell 5 and undergo a reduction reaction, generating a metal deposit in the area to be plated on the plating surface, thereby completing the electroplating work of the battery cell 5.

[0030] Optionally, the first conveying mechanism 11 can be a belt conveying mechanism, a roller conveying mechanism, a plate chain conveying mechanism, a chain conveying mechanism, etc.

[0031] Please refer to Figure 1 , preferably, in some embodiments, the first conveying mechanism 11 includes a first roller group 111 and a second roller group 112 that are connected. Along the height direction of the electroplating device (taking Figure 1 as an example, the height direction is Figure 1 the Z direction in Figure 1 , which can be understood as the direction from the inside to the outside or from the outside to the inside perpendicular to the paper in ), the second roller group 112 is located above the first roller group 111, and both the battery cell 5 and the conductive member 6 are located between the first roller group 111 and the second roller group 112. The first roller group 111 and the second roller group 112 are configured to clamp and convey the battery cell 5. Since the battery cell 5 needs to be immersed in the plating solution, the second roller group 112 is provided on the first roller group 111. The second roller group 112 plays a role in limiting the battery cell 5, preventing the battery cell 5 from floating and moving, and ensuring the stability during the electroplating process.

[0032] It can be understood that the transmission methods of the first conveying mechanism 11 are as follows but are not limited to: the first roller group 111 is the driving roller group, and the second roller group 112 is the driven roller group. Or the first roller group 111 is the driving roller group, and the second roller group 112 is the driven roller group. The specific structures of both are conventional roller conveying devices and will not be elaborated here.

[0033] Please refer to Figure 1 , in some embodiments, the electroplating device further includes a first sensor 13, and the first sensor 13 is electrically connected to the second conveying mechanism 12. The first sensor 13 is configured to place a conductive member 6 at the downstream end of the battery cell 5 when detecting the battery cell 5. Exemplarily, the first sensor 13 can be a photoelectric sensor, an infrared sensor, an ultrasonic sensor, etc.

[0034] Specifically, in one implementation, when the first sensor 13 senses that the first battery cell 5 enters the first conveying mechanism 11 and is about to be conveyed into the electroplating tank by the first conveying mechanism 11, it transmits an electrical signal to the PCL control system, so that the PCL control system controls the second conveying mechanism 12 to place the conductive member 6 in front of the first battery cell 5. When the first battery cell 5 starts electroplating to generate current, the presence of the conductive member 6 can stabilize the current of the first battery cell 5 and reduce the occurrence of virtual plating of the first battery cell 5. Further, in this way, when the first sensor 13 detects that the second battery cell 5 appears on the second conveying mechanism 12, it controls the second conveying mechanism 12 to move the conductive member 6 at the downstream end out.

[0035] In other implementations, when the second battery cell 5 enters the first conveying mechanism 11, the first conveying mechanism 11 starts to start conveying the battery cell 5 into the electroplating tank for electroplating. The first sensor 13 can be used to sense the second battery cell 5, determine that the first conveying mechanism 11 is about to start, and transmit an electrical signal to the PCL control system, so that the PCL control system controls the second conveying mechanism 12 to place the conductive member 6 in front of the first battery cell 5, thereby being able to place the conductive member 6 in front of the first battery cell 5 before the first battery cell 5 is electroplated. Further, in this way, when the first sensor 13 detects that the third battery cell 5 appears on the second conveying mechanism 12, it controls the second conveying mechanism 12 to move the conductive member 6 at the downstream end out.

[0036] Please refer to Figure 1, in some embodiments, the electroplating apparatus further includes a second sensor 14, and the second sensor 14 is electrically connected to the second conveying mechanism 12. The second sensor 14 is configured to place the conductive member 6 at the upstream end of the last cell when no cell 5 is detected within a set time. In other words, when the second sensor 14 does not detect the cell 5, it means that no new cell 5 is being conveyed on the first conveying mechanism 11 at this time, and the last cell 5 has been conveyed. Placing the conductive member 6 at the upstream end of the last cell 5 can evenly distribute the current on the last cell 5. It should be noted that in the embodiments of the present application, the set time refers to the time difference between the same position of two adjacent cells 5 passing through the second sensor 14. Exemplarily, the second sensor 14 can be a photoelectric timing sensor, an infrared timing sensor, a ultrasonic timing sensor, etc.

[0037] Please refer to Figure 1 and Figure 2 , in some embodiments, the second conveying mechanism 12 includes a moving component 121 and a grasping component 122. The moving component 121 is configured to drive the grasping component 122 to move along the Figure 1 shown X direction, and the grasping component 122 is configured to grasp and place the conductive member 6 on the first conveying mechanism 11. Optionally, the moving component 121 can be a gear-rack moving component, a lead screw moving component, a synchronous belt moving component, a linear motor moving component, etc.; the grasping component can be a manipulator component or a suction cup component.

[0038] Please refer to Figure 1 and Figure 2 , in some embodiments, the moving component 121 includes a moving driver 1211, a synchronous belt 1212, and a synchronous shaft 1213. The output end of the moving driver 1211 is connected to the synchronous shaft 1213, the synchronous belt 1212 is wound around the synchronous shaft 1213, and the synchronous belt 1212 is connected to the grasping component 122. The moving driver 1211 drives the synchronous shaft 1213 to rotate, thereby driving the synchronous belt 1212 to rotate, so that the grasping component 122 moves along the extending direction of the synchronous belt 1212 (i.e., the Figure 2 shown A-A direction). Exemplarily, the moving driver 1211 can be a servo motor or a stepper motor.

[0039] Please refer to Figure 1 and Figure 2 , further, the moving component 121 further includes a slide rail 1214 and a slide table 1215 that are slidably connected. The slide table 1215 is fixedly connected to the synchronous belt 1212, the grasping component 122 is connected to the slide table 1215, and the slide table 1215 slides along the slide rail 1214 driven by the synchronous belt 1212, thereby driving the grasping component 122 to move. Adding the slide rail 1214 can improve the stability of the grasping component 122 when moving.

[0040] Please refer to Figure 1 and Figure 2 In some embodiments, the grasping assembly 122 includes a lifting driver 1221, a telescopic driver 1222, and a fixture 1223. The lifting driver 1221 is connected to the moving assembly 121. The output end of the lifting driver 1221 is connected to the telescopic driver 1222. The output end of the telescopic driver 1222 is connected to the fixture 1223. The fixture 1223 is configured to grasp the conductive member 6. Since the battery cell 5 needs to be immersed in the electroplating solution, the lifting driver 1221 is provided to enable the fixture 1223 to descend below the liquid level along the Figure 2 B-B direction shown. The telescopic driver 1222 is provided to enable the fixture 1223 to drive the conductive member 6 closer to or farther from the first conveying mechanism 11.

[0041] Please refer to Figure 2 In some embodiments, the lifting driver 1221 is configured to drive the telescopic driver 1222 to perform a lifting motion along a first direction (such as the Figure 2 B-B direction shown), and the telescopic driver 1222 is configured to drive the fixture 1223 to perform a telescopic motion along a second direction (such as the Figure 2 C-C direction shown). The second direction is configured to intersect the first direction. Since the conductive member 6 needs to be placed between the first roller set 111 and the second roller set 112, the telescopic driver 1222 can enable the fixture 1223 to extend into the gap between the first roller set 111 and the second roller set 112 from the side, and then place the conductive member 6. Exemplarily, the telescopic driver 1222 can be a telescopic motor or a telescopic cylinder.

[0042] Please refer to Figure 1 and Figure 2 Taking the process of placing the conductive member 6 between the first roller set 111 and the second roller set 112 by the second conveying mechanism 12 as an example, the lifting driver 1221 drives the telescopic driver 1222 to descend until the conductive member 6 is aligned with the gap between the first roller set 111 and the second roller set 112. When the output end of the telescopic driver 1222 extends, it drives the fixture 1223 to drive the conductive member 6 into the gap. When the output end of the telescopic driver 1222 retracts, it drives the fixture 1223 to drive the conductive member 6 out of the gap.

[0043] In some embodiments, the second conveying mechanism 12 further includes a limit inductor. The limit inductor is electrically connected to the moving assembly 121. The limit inductor is configured to stop driving the moving assembly 121 to move when it detects that the grasping assembly 122 moves to a preset position. The limit inductor is provided to prevent the moving assembly 21 from driving the grasping assembly 122 to move excessively and prevent the grasping assembly 122 from moving beyond the range.

[0044] Please refer toFigure 2 , Further, the limit sensor includes a first limit sensor 123 and a second limit sensor 124, and both the first limit sensor 123 and the second limit sensor 124 are electrically connected to the movement driver 1211 of the movement assembly 121. The first limit sensor 123 and the second limit sensor 124 are respectively arranged at both ends of the synchronous belt 1212 along its own length direction (i.e., Figure 2 the A-A direction shown), the preset position limited by the first limit sensor 123 is the starting position, and the preset position limited by the second limit sensor 124 is the end position. Exemplarily, the first limit sensor 123 and the second limit sensor 124 can be photoelectric limit sensors, capacitive limit sensors or electromagnetic limit sensors.

[0045] Please refer to Figure 2 , specifically, when the first limit sensor 123 detects that the grasping assembly 122 moves to one end (starting position) of the synchronous belt 1212, it transmits an electrical signal to the PCL control system, so that the PCL control system controls the movement driver 1211 to stop running. The second limit sensor 124 is configured to transmit an electrical signal to the PCL control system when it detects that the grasping assembly 122 moves to the other end (end position) of the synchronous belt 1212, so that the PCL control system controls the movement driver 1211 to stop running.

[0046] The working process of the electroplating device of the present application will be specifically described below with specific embodiments:

[0047] Please refer to Figure 1 and Figure 2 , when the first sensor 13 detects the first battery cell 5 located on the first conveying mechanism 11, the movement assembly 121 moves the grasping assembly 122 to the starting position, and the starting position is limited by the first limit sensor 123. The grasping assembly 122 drives the conductive member 6 to extend between the first roller group 111 and the second roller group 112, and makes the conductive member 6 located in front of the first battery cell 5. The movement assembly 121 moves synchronously with the first conveying mechanism 11, so that the grasping assembly 122 holds the conductive member 6 and keeps relative stillness with the first battery cell 5. The energizing mechanism is energized, and the first battery cell 5 starts electroplating. When the first sensor 13 detects the second battery cell 5, the grasping assembly 122 moves out the conductive member 6, and at this time, the movement assembly 121 synchronously returns to the starting position.

[0048] When the second sensor 14 fails to detect a new battery cell 5 being conveyed on the first conveying mechanism 11 within the set time, the grasping assembly 122 feeds the conductive member 6 between the first roller set 111 and the second roller set 112, and positions the conductive member 6 behind the last battery cell 5. The moving assembly 121 moves synchronously with the first conveying mechanism 11 to keep the conductive member 6 relatively stationary with respect to the last battery cell 5 until the second limit sensor 124 detects that the grasping assembly 122 has moved to the end position, which is limited by the second limit sensor 124, and then controls the moving assembly 121 to stop moving. The grasping assembly 122 removes the conductive member 6 from the first conveying mechanism 11.

[0052] In this application, unless otherwise clearly stipulated and defined, when there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.
