Description

Technical Field

[0001] This utility model relates to the technical field of chemical nickel plating equipment, specifically a chemical nickel plating device. Background Technology

[0002] Nickel plating is a method of depositing a layer of nickel onto metals or certain non-metals through electrolysis or chemical methods. It is divided into electroplating nickel and electroless nickel plating. Electroless nickel plating is a process in which metal ions in an aqueous solution are reduced by a reducing agent under certain conditions and precipitated onto the surface of a solid substrate. Electroless plating is a metal surface treatment technology. The electroless nickel plating process is simple, highly practical, and has many superior characteristics. Electroless nickel plating is widely used in the electroplating industry.

[0003] Currently available electroless nickel plating equipment typically involves clamping or placing the workpiece to be nickel-plated in a nickel plating frame before immersing it in the nickel plating bath. However, during the nickel plating process, the areas of the workpiece that come into contact with the clamping device or nickel plating frame cannot fully contact the solution in the nickel plating bath, resulting in insufficient nickel plating on the workpiece surface and reduced nickel plating quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electroless nickel plating apparatus that solves the problem that traditional nickel plating apparatuses cannot ensure sufficient contact between the solution and the workpiece during nickel plating, thus preventing insufficient nickel plating on the workpiece surface and improving the nickel plating quality and practicality of the electroless nickel plating apparatus.

[0006] Preferably, the driving mechanism includes a horizontal plate, a motor is mounted on the upper surface of the horizontal plate, and the lower end of the motor passes through the horizontal plate and is fixedly connected to the upper end of the rotating shaft.

[0007] Preferably, the lifting assembly includes a lead screw, the lower end of which is rotatably connected to the upper surface of the nickel plating bath, a movable block is threadedly connected to the side surface of the lead screw, a support rod is fixedly connected to the inner surface of the movable block, and one end of the support rod is fixedly connected to the side surface of the horizontal plate.

[0008] Preferably, the upper end of the lead screw passes through the support frame and is rotatably connected to the support frame, and a servo motor is fixedly connected to the upper end of the support frame.

[0009] Preferably, a pump body is fixedly installed on the front surface of the nickel plating tank, a conveying pipe is fixedly connected to one end of the pump body, a T-pipe is fixedly connected to one end of the conveying pipe, and one end of the T-pipe is fixedly connected to one side surface of the nickel plating tank.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a chemical nickel plating device, including a nickel plating pool 1, with support frames 3 fixedly connected to the upper surfaces of both ends of the nickel plating pool 1, a lifting assembly inside the support frame 3, a rotating shaft 402 on the inner side of the support frame 3, multiple sets of sliding grooves 406 on the side surface of the rotating shaft 402, a spring 407 fixedly connected to the inner wall of the sliding groove 406, a slider 408 fixedly connected to the lower end of the spring 407, the slider 408 being limited and slidably connected to the sliding groove 406, a side plate 405 fixedly connected to one end of the slider 408, a nickel plating frame 403 fixedly connected to one end of the side plate 405, a driving mechanism at the upper end of the rotating shaft 402, a support plate 101 fixedly connected to the inner wall of the nickel plating pool 1, a wedge block 102 fixedly connected to one end of the support plate 101, and the wedge block 102 being aligned with the nickel plating frame 403.

[0022] As a technical optimization of this utility model, the driving mechanism includes a horizontal plate 401. A motor 4 is installed on the upper surface of the horizontal plate 401. The lower end of the motor 4 passes through the horizontal plate 401 and is fixedly connected to the upper end of the rotating shaft 402. The driving mechanism can drive the nickel plating frame 403 to rotate, so that the nickel plating frame 403 can repeatedly pass through the wedge block 102 to make it bounce and vibrate, so that the workpiece inside the nickel plating frame 403 can fully contact the solution inside the nickel plating pool 1.

[0023] As a technical optimization of this utility model, the lifting assembly includes a lead screw 304. The lower end of the lead screw 304 is rotatably connected to the upper surface of the nickel plating tank 1. A moving block 303 is threadedly connected to the side surface of the lead screw 304. A support rod 302 is fixedly connected to the inner surface of the moving block 303. One end of the support rod 302 is fixedly connected to the side surface of the horizontal plate 401. The upper end of the lead screw 304 passes through the support frame 3 and is rotatably connected to the support frame 3. A servo motor 301 is fixedly connected to the upper end of the support frame 3. The servo motor 301, the moving block 303, and the lead screw 304 in the lifting assembly can drive the support rod 302 to move up and down, thereby facilitating the removal of workpieces inside the nickel plating frame 403 by the operator.

[0024] As a technical optimization of this utility model, a pump body 2 is fixedly installed on the front surface of the nickel plating tank 1. A conveying pipe 201 is fixedly connected to one end of the pump body 2, and a three-way pipe 202 is fixedly connected to one end of the conveying pipe 201. One end of the three-way pipe 202 is fixedly connected to one side surface of the nickel plating tank 1. Through the pump body 2, the conveying pipe 201 and the three-way pipe 202, the solution inside the nickel plating tank 1 can be further circulated and flushed onto the surface of the nickel plating frame 403 workpiece, and the workpiece can be made to contact the solution evenly, thereby further improving the nickel plating quality of the workpiece.

[0025] As a technical optimization of this utility model, a through hole 404 is provided on the lower surface of the nickel plating frame 403, and multiple sets of support columns are fixedly installed on the side surface of the nickel plating frame 403, so that the solution can quickly penetrate into the interior of the nickel plating frame 403 and come into contact with the workpiece.

[0026] In use, the servo motor 301 on the upper end of the support frame 3 is first started. The servo motor 301 drives the lead screw 304 to rotate clockwise. At this time, the lead screw 304 raises the horizontal plate 401 and the rotating shaft 402 through the support rod 302 and the moving block 303. Then, the worker puts the workpiece to be nickel-plated into the nickel plating frame 403. After that, the servo motor 301 is started to rotate counterclockwise, which lowers the rotating shaft 402 into the nickel plating tank 1. At the same time, the motor 4 and the pump body 2 are started. The motor 4 drives the rotating shaft 402 and the nickel plating frame 403 to rotate. Then, the nickel plating frame 403 will rotate during the rotation. As the nickel plating frame 403 passes through the wedge block 102, it will be squeezed and lifted. At this time, the slider 408 at one end of the side plate 405 will squeeze the spring 407. When the nickel plating frame 403 passes through the wedge block 102, it will be squeezed by the wedge block 102. At this time, the nickel plating frame 403 and the side plate 405 will suddenly drop due to the elastic force of the spring 407. During this process, the workpiece inside the nickel plating frame 403 will experience a short period of weightlessness. At this time, the workpiece will be suspended and fully in contact with the solution. At the same time, the workpiece can be shaken and moved, so that the workpiece can be fully nickel plated.
