[0035] See also Figure 3The electroplating drum 10 provided in the embodiment of the present application is now described. The electroplating drum 10 includes a drum body 1 and an electrode guide rod 2; the drum body 1 has a cross-shaped cross section, and the drum body 1 is recessed inward to form four grooves 11, and the length direction of each groove 11 is arranged along the axial direction of the drum body 1, and the angle between each groove 11 and the central axis of the drum body 1 is a right angle 12. Among them, the length direction of the groove 11 and the axial direction of the drum body 1 are Figure 3 The electrode guide rod 2 is installed in the drum body 1, and the two ends of the electrode guide rod 2 extend out of the drum body 1. This structure can realize the electroplating operation of the parts to be electroplated by connecting the electrode guide rod 2 with the external circuit and cooperating with the electroplating liquid contained in the drum body 1. The four right angles 12 can separate the multiple parts to be electroplated and prevent the stacking of multiple parts to be electroplated, thereby helping to improve the electroplating quality of the parts to be electroplated.

[0036] In one embodiment, see Figure 3 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the distances between the vertices of each right angle 12 and the central axis of the drum body 1 are the same. Specifically, the connecting line of the vertices of the four right angles 12 intersects the central axis of the drum body 1. This structure can ensure that the collision degree between each right angle 12 and the multiple parts to be electroplated is consistent, thereby improving the uniformity of the separation of the multiple parts to be electroplated, so that the electroplating quality of each part to be electroplated is not much different.

[0037] In one embodiment, see Figure 3 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the width of each groove 11 is the same, and the depth of each groove 11 is the same. Here, the width of the groove 11 can be understood as Figure 3 The length along the X-axis direction; the depth of the groove 11 can be understood as Figure 3 The length along the Z-axis direction. This structure can ensure that the shape of the groove 11 remains consistent, which is convenient for processing and manufacturing. Moreover, the collision degree of the grooves 11 of the same configuration on multiple parts to be electroplated can remain consistent.

[0038] In one embodiment, see Figure 4 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the electrode guide rod 2 includes a guide rod body 21 installed in the drum body 1 and a plurality of side rods 22 installed on the guide rod body 21. Both ends of the guide rod body 21 extend out of the drum body 1 respectively for conducting with an external circuit. The plurality of side rods 22 are divided into a plurality of groups, and the plurality of groups of side rods 22 are arranged along the circumferential annular array of the guide rod body 21, and the plurality of side rods 22 in each group of side rods 22 are arranged at intervals along the axial direction of the guide rod body 21. With this structure, when the drum body 1 rotates on the electrode guide rod 2, the plurality of side rods 22 can break up and separate the plurality of parts to be electroplated, thereby improving the electroplating quality of the plurality of parts to be electroplated.

[0039] In one embodiment, the length of each side rod 22 is less than the distance between the vertex of each right angle 12 and the central axis of the drum body 1. This structure can avoid collision between the side rod 22 and the right angle 12, ensuring that the drum body 1 can rotate on the electrode guide rod 2.

[0040] In one embodiment, see Figure 4 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, a plurality of groups of side rods 22 are staggered along the circumference of the guide rod body 21. Specifically, a plurality of side rods 22 in two adjacent groups of side rods 22 are staggered along the circumference of the guide rod body 21. In this structure, the plurality of groups of side rods 22 staggered can improve the effect of breaking up and separating a plurality of workpieces to be electroplated, and avoid a plurality of side rods 22 being blocked by other side rods 22 and unable to break up the workpieces to be electroplated.

[0041] See also Figure 1 and Figure 2 The embodiment of the present application also provides an electroplating device, including a frame 20, an electroplating drum 10 and a rotation drive assembly 30. The electroplating drum 10 is mounted on the frame 20, and the two ends of the electrode guide rod 2 are respectively mounted on the frame 20, and the drum body 1 can realize the rotation on the electrode guide rod 2. The rotation drive assembly 30 is mounted on the frame 20, and the rotation drive assembly 30 is connected to the electroplating drum 10. This structure, through the conduction between the electrode guide rod 2 and the external circuit, cooperates with the electroplating liquid contained in the drum body 1 to realize the electroplating operation of the electroplated parts. In the process of driving the electroplating drum 10 to rotate by the rotation drive assembly 30, the electroplated parts located inside the electroplating drum 10 can collide with the four right angles 12, and the four right angles 12 can break up and separate multiple electroplated parts to prevent the stacking of multiple electroplated parts, thereby helping to improve the electroplating quality of the electroplated parts.

[0042] In one embodiment, see Figure 1 and Figure 2 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, a first gear 3 is installed on the electroplating drum 10, specifically, the first gear 3 is installed on the drum body 1. The rotation drive assembly 30 includes a rotating shaft 301 rotatably mounted on the frame 20, a second gear 302 mounted on the rotating shaft 301, and a driving unit 303 mounted on the frame 20; the second gear 302 is meshed with the first gear 3, and the driving unit 303 is connected to the rotating shaft 301. In this structure, when the rotating shaft 301 is driven to rotate by the driving unit 303, the second gear 302 on the rotating shaft 301 can drive the first gear 3 to rotate, and then drive the drum body 1 to rotate, so that the electroplating operation of multiple parts to be electroplated can be realized.

[0043] In one embodiment, see Figure 2As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the diameter of the first gear 3 is greater than the diameter of the second gear 302. This structure can reduce the speed by driving the first gear 3 with a larger diameter to rotate through the second gear 302 with a smaller diameter, thereby reducing the rotation speed of the drum body 1 and avoiding damage to multiple parts to be electroplated due to excessive rotation speed.

[0044] In one embodiment, see Figure 1 and Figure 2 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the electroplating device further includes a transition gear 304 rotatably mounted on the frame 20, the transition gear 304 is disposed between the first gear 3 and the second gear 302, and the transition gear 304 is respectively meshed with the first gear 3 and the second gear 302. This structure can play a transition transmission role through the transition gear 304, thereby protecting the rotation of the drum body 1.

[0045] In one embodiment, the diameter of the transition gear 304 is the same as the diameter of the second gear 302. Alternatively, the diameter of the transition gear 304 is larger than the diameter of the second gear 302, and the diameter of the transition gear 304 is smaller than the diameter of the first gear 3, which can further achieve a deceleration effect.

[0046] In one embodiment, see Figure 1 and Figure 2 As a specific implementation of the electroplating drum 10 provided in the embodiment of the present application, the driving unit 303 includes a driven gear 3031 mounted on the rotating shaft 301, a driving gear (not shown) meshing with the driven gear 3031, and a driving motor (not shown) mounted on the frame 20, and the driving gear is mounted on the output shaft of the driving motor. In this structure, when the driving gear is driven to rotate by the driving motor, the driven gear 3031 meshing with the driving gear can drive the rotating shaft 301 to rotate together, thereby helping to improve the transmission efficiency of the driving motor.

[0047] In one embodiment, the diameter of the driving gear is smaller than the diameter of the driven paper wheel, which can play a deceleration role.

[0048] Optionally, the drive unit 303 may also be a belt transmission mechanism, or a motor directly connected to the rotating shaft 301, which is not limited here. Similarly, the rotation drive assembly 30 may also be a belt transmission mechanism, or a motor directly connected to the electrode guide rod 2, which is not limited here.

[0049] In one embodiment, see Figure 1The electroplating device may further include an electrode sheet 40 connecting the rotating shaft 301 and the electrode guide rod 2, one end of the electrode sheet 40 is connected to the electrode guide rod 2, and the other end of the electrode sheet 40 is in contact with the rotating shaft 301. The electrode guide rod 2 can be used as a cathode. In this structure, the rotating shaft 301 can be electrically connected to the electrode guide rod 2 through the electrode sheet 40, so that it is convenient to connect and conduct with an external circuit.
