Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology, specifically relating to a rotating hanger structure for electroplating. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. It utilizes electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (e.g., copper sulfate), and enhancing aesthetics.

[0003] There are many types of electroplating racks. For workpieces that are small or have holes, they are usually hung on the outside of the electroplating rack by hooks or through the holes. Then, the workpiece is moved into the electroplating tank by the lifting and lowering of the electroplating device for electroplating. However, the existing electroplating racks are usually fixed and cannot be easily rotated. The workpiece is simply immersed in the electroplating tank, which causes the concentration of the electroplating tank in contact with different parts of the workpiece to be different. This results in uneven distribution of the metal film on the workpiece surface, affecting the electroplating effect. Therefore, there is room for improvement in the practicality of existing electroplating racks. Utility Model Content

[0007] The mounting mechanism includes a C-shaped plate, with two connecting blocks fixed to the top of the C-shaped plate. The connecting blocks have connecting holes on their surfaces. Four supporting sleeves are fixed to the top of the inner wall of the C-shaped plate. Sliding rods are slidably connected to the inner walls of the supporting sleeves. Movable frames are fixed between the sliding rods on the left and right sides. Side plates are fixed to the surfaces of the sliding rods. There are a total of two side plates. A mounting bracket is fixed to the bottom of the two side plates. A rotating shaft is rotatably connected to the top of the inner wall of the mounting bracket. A rotating plate is fixed to the bottom of the rotating shaft. Multiple hooks are fixed to the bottom of the rotating plate.

[0008] As a preferred embodiment, the reciprocating drive mechanism includes a first geared motor, which is fixed to the top of the C-shaped plate. The output shaft of the first geared motor passes through the C-shaped plate and is fixed to a turntable. A drive rod is fixed to the bottom of the turntable and is located inside the movable frame.

[0009] As a preferred embodiment, the rotary drive mechanism includes a second geared motor, which is fixed to the bottom of the inner wall of the mounting frame. The output shaft of the second geared motor is fixed with a drive shaft, and the top end of the drive shaft is rotatably connected to the top of the inner wall of the mounting frame.

[0010] In a preferred embodiment, both the drive shaft and the rotating shaft are fixed with sprockets, and the sprockets on the left and right sides are connected by chain drive.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) This utility model significantly improves the quality control level of electroplating process through composite motion design. The coordinated operation of the mechanical structure enables the workpiece to generate a composite motion of rotation and horizontal reciprocating during the electroplating process. This dynamic processing method effectively overcomes the solution concentration gradient problem existing in traditional static electroplating. The fluid disturbance effect generated by the composite motion promotes the full exchange of electrolyte on the surface of the workpiece. In particular, it forms a vortex cleaning effect in the concave area with complex geometric features, eliminating the phenomenon of bubble retention and ion depletion.

[0017] (2) This utility model uses dual motors to drive independently, which reduces mechanical complexity while ensuring motion accuracy. The optimized design of multiple kinematic pairs effectively balances the load distribution and significantly improves the reliability of equipment operation. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 4 As shown, this utility model embodiment provides a rotary hanger structure for electroplating treatment, specifically including a hanging mechanism 1, on which a reciprocating drive mechanism 2 and a rotary drive mechanism 3 are provided. The hanging mechanism 1 includes a C-shaped plate 101, with two connecting blocks 102 fixed to the top of the C-shaped plate 101. The surface of the connecting blocks 102 has connecting holes. Four supporting sleeves 103 are fixed to the top of the inner wall of the C-shaped plate 101. Sliding rods 104 are slidably connected to the inner wall of the supporting sleeves 103. A movable frame 105 is fixed between the left and right sliding rods 104. Side plates 106 are fixed to the surface of the sliding rods 104. There are a total of two side plates 106. A mounting bracket 107 is fixed to the bottom of the two side plates 106. A rotating shaft 108 is rotatably connected to the top of the inner wall of the mounting bracket 107. A rotating plate 109 is fixed to the bottom of the rotating shaft 108. Multiple hooks 110 are fixed to the bottom of the rotating plate 109.

[0025] In this embodiment, the mounting mechanism 1 forms the main support frame through the C-shaped plate 101, which bears the overall load of the structure. The connecting block 102 provides a fixed interface with external equipment. The sliding cooperation between the support sleeve 103 and the slide rod 104 realizes the horizontal guiding function of the movable frame 105. The side plate 106 and the mounting bracket 107 form a rigid connection system. The layout of multiple hooks 110 can realize high-density mounting of workpieces. The rotating shaft 108 drives the hooks 110 to rotate through the rotating plate 109, realizing the workpiece rotation immersion.

[0026] Please see Figure 3As shown, the reciprocating drive mechanism 2 specifically includes a first geared motor 201, which is fixed to the top of the C-shaped plate 101. The output shaft of the first geared motor 201 passes through the C-shaped plate 101 and is fixed to a turntable 202. A drive rod 203 is fixed to the bottom of the turntable 202 and is located inside the movable frame 105. In this embodiment, the first geared motor 201 acts as a power source to drive the turntable 202 to perform circular motion. The drive rod 203 moves within the inner wall of the movable frame 105, causing the movable frame 105 to perform left-right reciprocating motion, thereby converting the rotational motion into the horizontal reciprocating motion of the movable frame 105, achieving the left-right movement effect during workpiece immersion.

[0027] Please see Figure 4 As shown, the rotary drive mechanism 3 specifically includes a second geared motor 301, which is fixed to the bottom of the inner wall of the mounting bracket 107. A drive shaft 302 is fixed to the output shaft of the second geared motor 301. The top end of the drive shaft 302 is rotatably connected to the top of the inner wall of the mounting bracket 107. Sprockets 303 are fixed to the surfaces of both the drive shaft 302 and the rotating shaft 108. The left and right sprockets 303 are connected by a chain drive. In this embodiment, the second geared motor 301 forms a transmission system through the sprockets 303 and the chain. The drive shaft 302 and the rotating shaft 108 rotate synchronously, ensuring that the rotating plate 109 can drive multiple workpieces to rotate synchronously. The independent control mode of the dual geared motors allows for free adjustment of the rotation and reciprocating speeds.

[0028] Please see Figures 1 to 4 As shown, a bearing 204 is fixed to the surface of the drive rod 203, and the surface of the bearing 204 is slidably connected to the inner wall of the movable frame 105. The bearing 204 replaces sliding friction with rolling friction, converting the rotational motion of the turntable 202 into the pure linear motion of the movable frame 105, thus reducing the coefficient of friction of the kinematic pair. A circular slide rail 112 is fixed to the bottom of the mounting bracket 107, and a slider 113 is slidably connected to the surface of the circular slide rail 112. The bottom of the slider 113 is fixedly connected to the top of the rotating plate 109. The circular slide rail 112 uses the track and the slider 113 to restrict the degree of freedom of the rotating plate 109, ensuring the stability of the rotation axis 108 and reducing the shaking of the rotating plate 109.

[0029] Please see Figures 1 to 4 As shown, a support rod 111 is fixed to the surface of the C-shaped plate 101, and the support rod 111 slides through the underside of the mounting bracket 107. The support rod 111, passing through the mounting bracket 107, forms a guide system, constraining the movement trajectory of the mounting bracket 107 through sliding contact to ensure the linearity of left and right movements. The hook 110 is made of stainless steel with a polished surface. Stainless steel is resistant to electrochemical corrosion, extending its service life, while polishing reduces contact resistance and forms a corrosion-resistant protective layer.

[0030] Specifically, in this embodiment, the operator sequentially hangs the workpiece to be processed on multiple stainless steel polishing hooks 110 at the bottom of the rotating plate 109. The entire fixture is connected to the lifting mechanism of the electroplating equipment through the mounting holes of the connecting block 102. After starting the electroplating program, the lifting mechanism immerses the entire fixture below the surface of the electroplating tank. At this time, the first reduction motor 201 and the second reduction motor 301 start synchronously and enter the working state. At the power output end of the first reduction motor 201, the turntable 202 begins to rotate at a uniform speed. The drive rod 203, supported by the bearing 204, converts the circular motion into the horizontal reciprocating linear motion of the movable frame 105. This motion is transmitted to the mounting frame 107 through the side plate 106, making... The rotating plate 109 and the suspended workpiece generate periodic lateral displacement. At the same time, the second reduction motor 301 drives the rotating shaft 108 to rotate continuously through the transmission system composed of the sprocket 303 and the chain. This rotational motion is transmitted to all hooks 110 through the rotating plate 109, causing the suspended workpiece to rotate at a constant speed around the vertical axis. When the horizontal reciprocating motion and the rotational motion combine, the workpiece forms a three-dimensional composite motion trajectory in the electroplating solution. This motion mode continuously disturbs the surrounding electrolyte, breaks the formation of the concentration boundary layer, promotes the uniform distribution of metal ions, and improves the electroplating effect. After the predetermined electroplating cycle is completed, the lifting mechanism lifts the hanger out of the liquid surface, and the operator can easily remove the processed workpiece.

[0031] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
