Figure 5 As shown, the second conductive block 53 and the third conductive block 52 are both ring-shaped, and preferably 12 conductive rods 51 are used. The current carrying capacity is improved by using multiple conductive rods 61 and multiple second conductive connectors 54. The multiple conductive rods 51 are evenly distributed, one end of the conductive rod 51 is fixedly installed on the third conductive block 52, and the other end is fixedly installed on the second conductive block 53 arranged in the hollow portion. The multiple second conductive connectors 54 are evenly distributed, one end of the second conductive connector 54 is fixedly installed on the bottom of the second conductive block 53, and the other end is fixedly installed on the terminal 55.

[0049] Ginseng Figure 2 As shown, the driving assembly 60 includes a driving motor 61, a transmission shaft 62 installed on the driving motor 61, and a positioning block 63 installed on the transmission shaft 62. The driving motor 61 is arranged on a base 80 below the trough body 10. The transmission shaft 62 is installed on the driving motor 61 through a reducer 64. The transmission shaft 62 passes through the third conductive block 52 and the hollow part from the bottom of the hollow part.

The limit block 631 is fixedly installed on the top of the transmission shaft 62. The diameter of the limit block 631 is larger than the diameter of the second through hole 421 to prevent the limit block 631 from passing through the second through hole 421.

[0051] Ginseng Figure 1 As shown, a cooling device 70 is fixed in the hollow portion, the first conductive component 30 and the second conductive component 50 are both extended into the cooling device for abutment, and the driving component 60 passes through the cooling device 70 and abuts against the first bracket 40 .

[0052] Further, see Figure 2As shown, the cooling device 70 includes a fixed block 71, which is fixed to the inner wall 13. The fixed block 71 is provided with an annular groove 72 and a third through hole 72. The second conductive block 53 is arranged in the annular groove 72.

A water inlet and a water outlet are provided on the side wall of the annular groove 72. The water inlet is connected to an external water source and is used to inject cooling water into the annular groove 72 to avoid heat and fire due to poor conductivity between the first conductive block 31 and the second conductive block 53.

[0053] The working principle of the electroplating device of the present invention is as follows:

[0054] The first bracket 40 with the workpiece 100 is lifted by a lifting device and moved to a designated position above the trough body 10 and lowered, so that the tooling frame 20 extends into the accommodating portion, and the conical block 632 is inserted into the second through hole 421. The weight of the first bracket 40 is pressed on the transmission shaft 62 through the support of the limit block 631. The first conductive block 31 extends into the annular groove 72 and abuts against the second conductive block 53. The driving motor 61 drives the rotating shaft 62 to rotate. Under the action of friction, the first bracket 40 also rotates. The current is introduced through the second conductive connecting member 54 and guided to the second conductive block 53 through the conductive rod 51. The first conductive block 31 rotates with friction with the second conductive block 53 driven by the rotation of the first bracket 40. The current is finally guided to the workpiece 100 on the tooling frame 20 through the second conductive block 53, the first conductive connecting member 33 and the conductive connecting plate 32, so that the workpiece 100 is electroplated in the electroplating solution.

[0055] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0056] The present invention drives the tooling frame to rotate through a driving component, thereby driving the workpiece on the tooling frame to rotate. The rotation of the workpiece can improve the uniformity of the coating on the surface of the workpiece.

[0057] The present invention realizes efficient current transmission by rotating and abutting the second conductive component with the first conductive component;

[0058] The rotating conductive device of the present invention can withstand a current of up to 45000A, thereby meeting the needs of workpiece electroplating.
