Description

Technical Field

[0001] This utility model relates to a tin plating equipment, specifically a tin plating equipment for VCM motor spring sheets. Background Technology

[0002] The VCM principle is similar to that of a loudspeaker, also known as a voice coil motor. It features high frequency response and high precision. Its main principle is to control the stretching position of the spring plate by changing the magnitude of the DC current in the coil inside the motor within a permanent magnetic field, thereby driving the up-and-down movement.

[0003] To increase the corrosion resistance of existing VCM motor springs, tin plating is generally required. This necessitates the use of tin plating equipment. For example, a processing device for increasing the corrosion resistance of VCM springs, applied for by our company with publication number CN221752520U, involves adding tin liquid to a plating bath and immersing the VCM springs in the plating solution for tin plating. A circulation filtration mechanism is also included to ensure the quality of the tin liquid. However, this equipment still has the following drawbacks: 1. The circulation pump is located inside the plating bath, and the high ambient temperature during operation can easily cause overheating and damage to the pump; 2. The circulation filtration mechanism is located inside the plating bath, which occupies a large area, thus only one receiving tank can be placed on the opposite side of the plating bath and the circulation filtration mechanism. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of providing a VCM motor spring sheet tin plating device that can accommodate more storage tanks and has an external circulation pump.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a VCM motor spring tin plating device is as follows:

[0006] The system includes a plating bath, with a filter seat extending outward from one side of the plating bath, and receiving tanks mounted on the other three sides of the plating bath. The filter seat is connected to the plating bath. A connecting seat is connected to the outside of the plating bath below the filter seat. A circulation pump is installed on the connecting seat. The inlet of the circulation pump is connected to the bottom of the plating bath through a first pipe, and the outlet of the circulation pump is connected to the filter seat through a second pipe. A filter plate is detachably connected inside the filter seat, and the molten tin inside the filter seat is filtered by the filter plate before flowing into the plating bath.

[0007] The filter base is located behind the plating bath; the filter plate includes an inclined filter plate that slopes upward from back to front, a transition filter plate connected to the upper end of the inclined filter plate, and a filter frame connected to the front of the transition filter plate; the lower end of the inclined filter plate abuts against the lower wall of the filter base; the transition filter plate slopes downward from back to front; the filter frame is spaced apart from the lower wall of the filter base.

[0008] The filter base has a liquid outlet on its front side; the position of the liquid outlet is lower than the height of the upper surface of the plating tank.

[0009] The filter plate is connected to mounting edges on both the left and right sides; the mounting edges on the left and right sides of the filter plate are respectively fixed to the two sides of the filter base by bolts.

[0010] An upper baffle is provided above the filter base.

[0011] The technical effects achievable by this utility model are as follows: The circulating pump of the VCM motor spring tin plating equipment is located outside the plating bath, specifically installed on the connecting seat below the filter seat. By placing the circulating pump externally, it is less affected by the temperature of the tin liquid during operation. Furthermore, a filter seat extends outward from one side of the plating bath, and the filter plate is installed inside the filter seat, thus not affecting the space inside the plating bath. Receiving slots can be hung on all three sides of the plating bath. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] See Figures 1 to 5 .

[0020] A VCM motor spring sheet tin plating device includes a plating bath 1, a filter seat 3 extending outward from one side of the plating bath 1, and receiving tanks 2 hanging on the other three sides of the plating bath 1; the filter seat 3 communicates with the plating bath 1, and a connecting seat 4 is connected to the lower part of the filter seat 3 on the outside of the plating bath 1, and a circulation pump 5 is installed on the connecting seat 4. The inlet of the circulation pump 5 is connected to the lower part of the plating bath 1 through a first pipe 6, and the outlet of the circulation pump 5 is connected to the filter seat 3 through a second pipe 7; a filter plate is detachably connected inside the filter seat 3, and the tin liquid inside the filter seat 3 is filtered by the filter plate. The filter is filtered before flowing into the plating bath 1. Specifically, the filter seat 3 is located at the rear of the plating bath 1. The filter plate includes an inclined filter plate 11 that slopes upward from back to front, a transition filter plate 12 connected to the upper end of the inclined filter plate 11, and a filter frame 13 connected to the front of the transition filter plate 12. The lower end of the inclined filter plate 11 abuts against the lower wall of the filter seat 3, the transition filter plate 12 slopes downward from back to front, and the filter frame 13 is spaced apart from the lower wall of the filter seat 3. More specifically, the filter seat 3 has an outlet 14 on the front side, and the position of the outlet 14 is lower than the height of the upper surface of the plating bath 1.

[0021] In use, this invention contains molten tin in a plating tank 1. Receiving tanks 2 are hung on the left, right, and front sides of the plating tank 1, with their bodies immersed in the molten tin. Tin plating is performed by placing the VCM motor springs to be tinned into these three receiving tanks 2. During use, the circulating pump 5 continuously pumps the molten tin from the plating tank 1 into the filter seat 3. The molten tin in the filter seat 3 is filtered by the filter plates before flowing back into the plating tank 1. Therefore, the molten tin is continuously filtered, ensuring its quality. During the filtration process, the molten tin in the filter seat 3... The molten tin is first filtered by the inclined filter plate 11. After filtration by the inclined filter plate 11, it flows out through the gap between the filter frame 13 and the lower wall of the filter seat 3 and then into the plating bath 1. When there are too many impurities on the inclined filter plate 11 and it becomes clogged, the molten tin flows out from the upper end of the inclined filter plate 11 and enters the transition filter plate 12 and the filter frame 13. After being filtered by the transition filter plate 12 and the filter frame 13, it flows into the plating bath 1. When the transition filter plate 12 and the filter frame 13 are also clogged, the molten tin is not filtered and directly exits from the outlet 14. By setting the position of the outlet 14 to be lower than the height of the upper surface of the plating bath 1, the overflow of molten tin can be effectively prevented.

[0022] Preferably, the filter plate is connected to the mounting edges 21 on both the left and right sides, and the mounting edges 21 on the left and right sides of the filter plate are fixed to the filter base 3 by bolts. The filter plate of this utility model is detachable, which is convenient for subsequent replacement. Specifically, an upper baffle 31 is provided on the top of the filter base 3, which can prevent the molten solder of the filter base 3 from splashing.
