The top of the centrifuge plating tank moving module is provided with corresponding nickel plating components, tin plating components, and water injection components, etc. The nickel plating components, tin plating components, and water injection components are evenly spaced along the length of the frame 1. When nickel plating is required, the first driving device 6 drives the moving box 2 to move below the nickel plating components. During the movement, the two first bellows-style protective covers 3 adaptively stretch and adjust. The third driving device 8 drives the top cover 5 to open and close, which facilitates the injection of nickel plating solution and prevents solution splashing during operation. After the solution is added, the second driving device 7 drives... The plating tank assembly 4 rotates to begin centrifugal electroplating. After nickel plating is completed, the first drive device 6 drives the moving box 2 to the bottom of the water injection assembly to clean the plating tank. After cleaning, the first drive device 6 drives the moving box 2 to the bottom of the tin plating assembly for tin plating.

The first driving part 64 is installed inside the movable box 2, and the output end of the first driving part 64 is equipped with the gear 62, which meshes with the toothed rail 63. The two first bellows-type protective covers 3 and the movable box 2 are covered by the toothed rail 63 and the slide rail 64. In this embodiment, there are two slide rails 64, which are respectively installed on the left and right sides of the frame 1.

During operation, the first drive unit 61 drives the gear 62 at its output end to rotate. The gear 62 meshes with the gear rail 63, thereby causing the movable box 2 to move back and forth on the slide rails 64 via the sliders 65. Furthermore, during the movement, the two first accordion-style protective covers 3 adaptively extend and retract, and together with the movable box 2, completely cover and enclose the two slide rails 64 and the gear rail 63 to prevent corrosion from steam or chemicals, thereby improving the service life of the first drive unit 6.

In this embodiment, the electroplating tank 42 is prior art, specifically referring to patent CN222251073U. The first bearing seat 91 is located inside the movable box 2, and the second bearing seat 92 is located above the first bearing seat 91. During installation, one end of the rotating rod 41 is installed on the first bearing seat 91, and one end of the rotating rod 41 protrudes from the bottom of the second bearing seat 91 and is connected to the output end of the second driving device 7. The other end of the rotating rod 41 is installed on the second bearing seat 92, and the other end of the rotating rod 41... One end protrudes from the top of the second bearing seat 92 and is connected to the bottom of the electroplating cylinder 42. During operation, the second driving device 7 drives the rotating rod 41 to rotate, and the rotating rod 41 drives the electroplating cylinder 42 to rotate, thereby achieving the purpose of centrifugal electroplating. The liquid thrown out by the electroplating cylinder 42 is blocked by the top cover 5 and falls into the water-blocking basin 94, and is discharged from the drain outlet 943. Specifically, the drain outlet 943 is changed from a bottom-mounted structure to a side-mounted structure, which makes the drain outlet 943 easier to install, easier to maintain, and prevents leakage.

[0036] like Figure 1-3As shown, the water-retaining basin 94 is provided with a first baffle 941 and a second baffle 942; the first baffle 941 is located on the outer periphery of the second bearing seat 92, the second baffle 942 is located on the outer periphery of the first baffle 941, and a drainage area 944 is formed between the second baffle 942 and the inner wall of the drainage tray 94, the drainage area 944 being connected to the drainage outlet 943; the plating tank assembly 4 also includes a third baffle 43, the third baffle 43 being installed at the bottom of the electroplating tank 42, and the bottom of the third baffle 43 covering the outer periphery of the top of the second baffle 942. In this embodiment, the first baffle 941 is located on the outer periphery of the second bearing seat 92, thereby preventing liquid ejected from the electroplating tank 42 from entering the interior of the second bearing seat 92. The second baffle 942 is provided on the outer periphery of the first baffle 941. The second baffle 942 prevents liquid from the drainage area 944 from entering the area between the first baffle 941 and the second baffle 942. However, the second baffle 942 is set at a low height. Therefore, the third baffle 43 is added to the bottom of the electroplating tank 42, so that the bottom of the third baffle 43 covers the outer periphery of the top of the second baffle 942, further improving the water-blocking and waterproofing performance.

[0037] like Figure 1-2 As shown, the second driving device 7 includes a first pulley 71, a second pulley 72, a transmission belt 73, and a second driving unit 74. The second driving unit 74 is mounted on the mounting bracket 93, with its output shaft facing downwards. The first pulley 71 is mounted on the output shaft of the second driving unit 74, and the second pulley 72 is mounted on the rotating rod 41. The second pulley 72 is connected to the first pulley 71 via the transmission belt 73. In this embodiment, the second driving unit 74 is a motor. The output shaft of the second driving unit 74 faces downwards, so even if steam enters the output shaft of the second driving unit 74, it will flow downwards and be discharged under gravity after liquefying into liquid. This avoids the phenomenon of liquid accumulating inside the motor due to the output shaft of the second driving unit 74 facing upwards, thus improving the service life of the second driving unit 74. During operation, the second driving unit 74 drives the first pulley 71 to rotate, and the first pulley 71 drives the second pulley 72 to rotate via the transmission belt 73, thereby causing the rotating rod 41 to rotate.

In this embodiment, the output end of the third driving device 8 extends and retracts, thereby causing the top cover 5 to swing along the rotating shaft 96 via the connector 97, thus opening and closing the top cover 5 conveniently and quickly. Furthermore, the first protective shell 98 covers the fixed base 95, the rotating shaft 96 and the connector 97, and the second protective shell 99 covers the third driving device 8. The first protective shell 98 and the second protective shell 99 play a protective role, preventing damage from external collisions, and can also prevent steam and liquid from entering and corroding to a certain extent.
