[0052] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0053] like Figure 1 As shown, the photovoltaic cell electroplating process automatic working equipment provided in this embodiment includes: a box body 100, a suction cup component 200, a first rotating component 300 and a second rotating component 400; the box body 100, the box body 100 is placed with a battery cell; the suction cup component 200, the suction cup component 200 is used to absorb the battery cell; the first rotating component 300, the first rotating component 300 is connected to the suction cup component 200, and the first rotating component 300 is used to drive the suction cup component 200 to do a flipping motion; the second rotating component 400, the second rotating component 400 is connected to the box body 100, the second rotating component 400 is connected to the first rotating component 300, and the second rotating component 400 is used to drive the first rotating component 300 to do a translational motion.

[0054] Specifically, after the suction cup component 200 absorbs the battery cell on the box body 100, the suction cup component 200 performs a flipping motion under the drive of the first rotating component 300 to turn the battery cell over. At the same time, under the drive of the second rotating component 400, the suction cup component 200 performs a translational motion to move the battery cell to each process.

[0055] In addition, in the prior art, the horizontal electroplating method generally places the battery cell on top of a conductive roller, which can rotate and serve as an electrode. The roller drives the battery cell to move forward while contacting the electroplating solution for electroplating. During electroplating, this method may cause metal ions to be deposited on the roller surface, which affects the electroplating effect and easily causes fragments. However, the present embodiment uses a suction cup member 200 to adsorb the battery cell, so that metal ion precipitation will not occur and the electroplating effect will not be affected.

[0056] The suction cup component 200 specifically includes a suction cup body and a vacuum pump. A plurality of air holes 210 are arranged on the suction cup body. The vacuum pump is connected to the air holes 210 through pipelines. The vacuum pump generates suction force, which acts on the battery cell through the air holes 210, thereby adsorbing the battery cell onto the suction cup body.

[0057] The automatic working equipment for the photovoltaic cell electroplating process provided in this embodiment sucks the battery cell on the box 100 through the suction cup component 200, the first rotating component 300 can drive the suction cup component 200 to perform a flipping movement, and the second rotating component 400 can drive the first rotating component 300 and the suction cup component 200 to perform a translational movement together. After the suction cup component 200 sucks the battery cell, the first rotating component 300 and the second rotating component 400 work together to flip and translate the battery cell to each process area, so that the battery cell can be quickly moved between each process under the suction of the suction cup component 200, thereby increasing the transportation efficiency and reducing the time cost, thereby alleviating the technical problems of low transportation efficiency of battery cells and high electroplating time cost in the electroplating process in the prior art.

[0058] Based on the above embodiments, Figure 2 As shown, in an optional embodiment, the first rotating component 300 in the automatic working equipment of the photovoltaic cell electroplating process provided in this embodiment includes a first fixed part and a first transmission part; specifically, the first fixed part is specifically a first driving motor, and the first transmission part is specifically a first driving rod. The driving end of the first driving motor can rotate along its own axial direction, and the driving end of the first driving motor is connected to the first driving rod in a transmission manner. Under the drive of the first driving motor, the first driving rod rotates around the driving end of the first driving motor, so that the first transmission part can rotate around the first fixed part, and since the end of the first transmission part away from the first fixed part is connected to the suction cup component 200, the suction cup component 200 can rotate around the first fixed part, thereby realizing the flipping movement of the suction cup component 200.

[0059] In an optional embodiment, the second rotating component 400 includes a second fixed portion and a second transmission portion; specifically, the second fixed portion is a second drive motor, and the second drive motor is fixedly installed on the box body 100, and the second transmission portion is a second drive rod. The second drive motor provides driving force for the second drive rod, so that the second drive rod can rotate along its own axial direction, and because the end of the second transmission portion away from the second fixed portion is connected to the first fixed portion, the first fixed portion can perform rotational motion, thereby driving the suction cup component 200 to perform translational motion together.

[0060] It should be noted that the second transmission part is arranged perpendicular to the surface of the box body 100 to ensure that when the second transmission part rotates, the translational motion plane of the suction cup component 200 is parallel to the surface of the box body 100 , thereby ensuring the translational motion of the suction cup component 200 .

[0061] In an optional embodiment, the automatic working equipment for the photovoltaic cell electroplating process also includes a connecting member 500; specifically, the connecting member 500 can be configured as a connecting block or a connecting rod, one end of the connecting member 500 is connected to the first transmission part, and the other end of the connecting member 500 is connected to the suction cup member 200, and the suction cup member 200 is connected to the first transmission part through the connecting member 500. The setting of the connecting member 500 increases the connection length between the suction cup member 200 and the first transmission part, making the first transmission part, the connecting member 500 and the suction cup member 200 longer, thereby increasing the translational movement range of the suction cup member 200, ensuring that the suction cup member 200 can enter each process.

[0062] In an optional embodiment, the box body 100 has a loading area 130 and a unloading area 140, and the box body 100 is provided with a loading belt 110 and a unloading belt 120; the feeding end of the loading belt 110 is located in the loading area 130, and the belt conveying direction of the loading belt 110 is away from the loading area 130, so that the loading belt 110 can drive the battery cells in the loading area 130 to move, and the loading belt 110 conveys the battery cells in the loading area 130 to the bottom of the suction cup component 200, so that the suction cup component 200 can absorb the battery cells. The suction cup component 200 is driven by the first rotating component 300 and the second rotating component 400 to perform pickling, electroplating and cleaning processes in sequence. After the process is completed, the suction cup component 200 places the absorbed battery cells on the unloading belt 120, and the unloading belt 120 moves the battery cells to the unloading area 140 for unloading.

[0063] In addition, optionally, the box body 100 includes an upper box body 100 and a lower box body 100, the upper box body 100 is used to install the first rotating component 300, the second rotating component 400, the suction cup component 200 and the pickling tank 600, the electroplating tank 700, and the cleaning tank 800 described below, and the lower box body 100 is used to install the control system, the power system and the power supply, the power supply provides electrical energy to the control system and the power system, the control system generates a control signal to control the operation of the loading belt 110, the unloading belt 120, the first rotating component 300 and the second rotating component 400, and the power system provides power to the loading belt 110 and the unloading belt 120, so that the loading belt 110 and the unloading belt 120 drive the battery cells to move under the drive of the power system.

[0064] In an optional embodiment, the box body 100 is provided with a pickling tank 600 for containing a pickling solution to facilitate the pickling process; the box body 100 is provided with a plating tank 700 for containing a plating solution to facilitate the electroplating process; the box body 100 is provided with a cleaning tank 800 for containing pure water to facilitate the cleaning process.

[0065] After the suction cup component 200 sucks up the battery cell, it is flipped and translated under the action of the first rotating component 300 and the second rotating component 400, first moved to the pickling tank 600, and after the pickling process is completed, moved to the electroplating tank 700, and after the electroplating process is completed, moved to the cleaning tank 800. After the cleaning process is completed, the suction cup component 200 moves the battery cell to the unloading belt 120 for unloading.

[0066] It should be noted that when the suction cup component 200 absorbs the battery cell on the loading belt 110, the battery cell is adsorbed under the suction cup component 200. Under the action of the first rotating component 300 and the second rotating component 400, the suction cup component 200 is flipped and translated to the top of the pickling tank 600. At this time, the battery cell is located above the suction cup component 200 and the pickling process is carried out. During the subsequent electroplating process and cleaning process, the battery cell is always located above the suction cup component 200. After each process is completed, it is flipped and translated again, and the battery cell is located below the suction cup component 200 and placed on the unloading belt 120 for unloading. Since only one side of the battery cell is completed during pickling, electroplating and cleaning, after unloading, the battery cell needs to be flipped over for loading again. Repeat the above operation again to complete the pickling, electroplating and cleaning processes on both sides of the battery cell.

[0067] In an optional embodiment, the pickling tank 600 , the electroplating tank 700 and the cleaning tank 800 are all located within the translational movement range of the suction cup member 200 .

[0068] Specifically, driven by the second rotating member 400, the suction cup member 200 can perform translational circular motion on a horizontal plane. In order to ensure that the battery cells can undergo pickling, electroplating and cleaning processes in sequence, the pickling tank 600, the electroplating tank 700 and the cleaning tank 800 are arranged in sequence at intervals within the range of the translational circular motion, making the structure more compact and reducing the volume of the box 100.
