[0041] Among them, the liquid inlet mechanism 2 includes a pneumatic adsorption fixed frame 22, a push rod slide 23, a liquid inlet transmission mechanism 24, and a liquid inlet parallel four-bar mechanism 25. The battery cell 21 is adsorbed onto the pneumatic adsorption fixed frame 22 through negative pressure gas, the push rod slide 23 is connected to the liquid inlet transmission mechanism 24 through a nut, and the liquid inlet parallel four-bar mechanism 25 is connected to the pneumatic adsorption fixed frame 22.
[0042] Among them, the liquid inlet mechanism 2 is first rotated into a vertical direction through the liquid inlet parallelepiped mechanism 25 and is located on the surface of the electroplating liquid. After the battery cell 21 is adsorbed onto the pneumatic adsorption fixture 22, the liquid inlet mechanism 2 is rotated 90 degrees counterclockwise to immerse the battery cell 21 in the electroplating liquid; the liquid inlet transmission mechanism 24 is actuated, and the push rod slide 23 moves forward under the action of the nut and lead screw to push the battery cell 21 into the entrance of the horizontal electroplating line 5.
[0043] The horizontal electroplating line 5 includes an electroplating fixed frame 51, a top V-shaped conveying chain 53, an anode plate 54, and a bottom V-shaped conveying chain 57; the electroplating fixed frame 51 is placed in the electroplating tank 1, the top V-shaped conveying chain 53 is arranged on the top of the electroplating fixed frame 51, and the bottom V-shaped conveying chain 57 is arranged on the bottom of the electroplating fixed frame 51; the anode plate 54 is fixed on the electroplating fixed frame 51. The anode plate 54 can be a flat anode or a mesh anode.
[0044] The horizontal electroplating line 5 also includes a cell size adjustment mechanism 52, which is arranged above the electroplating fixture 51, and the manipulator 55 is fixed on the cell size adjustment mechanism 52, and the cell size adjustment mechanism 52 is used to adjust the height of the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57. The horizontal electroplating line 5 can adapt to various sizes of cells such as 182*91cm, 210*105cm, 182*105cm, etc.
[0045] The upper and lower ends of the flat conductive brush 56 are respectively engaged with the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57; the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57 are used to convey the flat conductive brush 56 and the battery cell 21 to move forward together; the top V-shaped conveyor chain 53 is connected to the cathode of the power supply for contact and conduction, so that the flat conductive brush 56 can electroplate the grid lines on the surface of the battery cell 21 on the horizontal electroplating line 5. The contact surface between the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57 and the battery cell 21 adopts rubber gaskets, and the materials of the rubber gaskets include PTFE, nitrile rubber, and polyurethane rubber.
[0046] Among them, after the liquid inlet mechanism 2 is loaded, the battery cell 21 and the flat conductive brush 56 move forward along the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57 on the horizontal electroplating line 5. When the flat conductive brush 56 passes through the narrowing structure 81 provided at one end of the electroplating fixing frame 51, the flat conductive brush 56 contacts the grid line on the surface of the battery cell 21 for electroplating.
[0047] Among them, after the electroplating is completed, the battery cell 21 and the flat conductive brush 56 leave the horizontal electroplating line 5 along the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57 on the horizontal electroplating line 5. When the flat conductive brush 56 passes through the narrowing structure 81 provided at the other end of the electroplating fixing frame 51, the flat conductive brush 56 is separated from the grid line on the surface of the battery cell 21; the robot 55 puts the flat conductive brush 56 after the electroplating is completed into the de-plating tank 4 for de-plating treatment.

[0050] The liquid outlet mechanism 6 includes a liquid outlet fixing frame 62 and a liquid outlet parallelogram mechanism 61 , and the liquid outlet parallelogram mechanism 61 is connected to the liquid outlet fixing frame 62 .
[0051] like Figure 1 As shown, the battery cell 21 is transported to the liquid inlet mechanism 2 by a conveyor belt or an automated suction cup. At this time, the liquid inlet mechanism 2 is rotated to a vertical direction through the liquid inlet four-bar mechanism and is located on the surface of the electroplating liquid. After the loading is completed, the liquid inlet mechanism 2 is rotated 90 degrees counterclockwise and immersed in the electroplating liquid, and is connected to the entrance of the horizontal electroplating line 5.
[0052] like Figure 2 As shown, the liquid inlet transmission mechanism 24 is in action, and the push rod slide 23 moves forward under the action of the nut screw, pushing the battery cell 21 into the entrance of the horizontal electroplating line 5. The pushing speed of the battery cell 21 is the same as the transmission speed of the horizontal electroplating line 5. The battery cell 21 is pushed between the top V-shaped conveying chain 53 and the bottom V-shaped conveying chain 57 of the horizontal electroplating line 5. At the same time, the pneumatic adsorption fixing frame 22 is exhausted, and the battery cell 21 moves forward under the conveyance of the top V-shaped conveying chain 53 and the bottom V-shaped conveying chain 57; at the same time, the manipulator 55 takes out the flat conductive brush 56 that has been stripped in the stripping tank 4, and inserts it into the bottom V-shaped conveying chain 57 of the horizontal electroplating line 5. The adjacent chain units of the bottom V-shaped conveying chain 57 are meshed with the teeth of the flat conductive brush 56. The flat conductive brush 56 and the battery cell 21 move forward synchronously with the bottom V-shaped conveying chain 57. At the same time, the relative position of the flat conductive brush 56 and the battery cell 21 remains unchanged, and at this time, the flat conductive brush 56 and the battery cell 21 are not in contact with each other for conduction, completing the loading action.
[0053] like Figure 8As shown, when the cell is loaded, the cell 21 and the flat conductive brush 56 move forward along with the bottom V-shaped conveyor chain 57. When the flat conductive brush 56 passes through the narrowing structure 81 at one end of the electroplating fixture 51, the flat conductive brush 56 located on both sides of the cell 21 is under the action of the narrowing structure 81. The conductive brush 563 on the flat conductive brush 56 contacts the grid line on the surface of the cell 21. The top V-shaped conveyor chain 53 has the same function as the bottom V-shaped conveyor chain 57. At the same time, the top V-shaped conveyor chain 53 is connected to the cathode of the power supply to contact and conduct electricity, and the grid line on the surface of the cell 21 is electroplated. Figure 6 shown.
[0054] like Figure 4 As shown, after the electroplating is completed, the battery cell 21 and the flat conductive brush 56 leave the horizontal electroplating line 5 under the action of the top V-shaped conveyor chain 53 and the bottom V-shaped conveyor chain 57. There is also a narrowing structure 81 at the outlet of the electroplating fixture 51. The flat conductive brush 56 located on both sides of the battery cell 21 is under the action of the narrowing structure 81. The conductive brush bristles 563 on the flat conductive brush 56 are separated from the grid lines on the surface of the battery cell 21. When the battery cell 21 and the flat conductive brush 56 are separated from the horizontal electroplating line 5, the robot 55 removes the flat conductive brush 56 after the electroplating is completed and puts it into the de-plating tank 4 for de-plating.
[0055] like Figure 3 As shown, after the battery cell 21 is electroplated, the horizontal electroplating line 5 transports the battery cell 21 to the liquid outlet mechanism 6, and the liquid outlet mechanism 6 rotates 90 degrees counterclockwise to lift the electroplated battery cell 21 above the electroplating liquid level, completing an electroplating process.
[0056] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
