[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. In the actual electroplating process, the electroplating solution is generally in a static state. As the electroplating proceeds, the cations in the solution will be unevenly distributed, which will affect the electroplating effect. Summary of the invention

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4 , to solve the problem of increasing electroplating efficiency.

[0026] Two parallel longitudinal rods 101 are rotatably connected to the two sides of the slide 11 respectively, and two slide grooves 102 are symmetrically arranged on each longitudinal rod 101. Each cross rod 103 is slidably connected between the two corresponding slide grooves 102 on the two longitudinal rods 101. Each cross rod 103 and the corresponding longitudinal rod 101 are locked with screws, and each cross rod 103 is provided with two clamping mechanisms 12.

[0027] First, the parts to be electroplated are clamped between multiple clamping mechanisms 12, and then the two cross bars 103 are slid so that the geometric center of the parts is located on the rotation center of the longitudinal bar 101, and then the screws at both ends of the cross bar 103 are used to fix the cross bar 103 and the longitudinal bar 101 to each other. When electroplating is performed, the longitudinal bar 101 is driven to rotate, thereby driving the two cross bars 103 to rotate, and then driving the parts fixed by the clamping mechanism 12 to rotate synchronously, and then during the electroplating process, the parts are moved in the electroplating solution, thereby avoiding the situation in which the electroplating solution is stationary during continuous processing, resulting in uneven deposition inside the solution, and then resulting in uneven surface of the parts after electroplating. When the present invention is working, the slide 11 is connected to the negative pole of the DC power supply of the power supply through a wire, and then connected to the part to be electroplated through the longitudinal bar 101, the cross bar 103, the clamp 201 and the metal contact 202, and the negative pole of the DC power supply is placed in the electroplating solution, thereby realizing the electroplating work.

[0028] like Figure 3 and Figure 4 , in order to solve the problem of fixing parts by the clamping mechanism 12.

[0029] The clamping mechanism 12 includes two clamps 201, each of which is rotatably connected to the corresponding cross bar 103, and one end of each clamp 201 located between the two cross bars 103 is fixedly connected to a rubber clamp 205, and each rubber clamp 205 is provided with a plurality of metal contacts 202 penetrating the rubber clamp 205.

[0030] By pressing one end of the clamping mechanism 12 located outside the two cross bars 103, the two rubber clamps 205 are separated, and then the part of the part that does not need to be electroplated is fixed between the two rubber clamps 205. The rubber clamps 205 are small in size to avoid contact with the surface of the part that needs to be electroplated to affect the electroplating effect. The two ends of the metal contact 202 are slightly indented compared to the rubber clamps 205, and the two ends are hemispherical, thereby clamping the part.

[0031] Afterwards, the rubber clamp 205 is squeezed and deformed, so that the metal contact 202 contacts the part for electroplating. At the same time, the squeezed rubber clamp 205 can seal the metal contact 202 to prevent metal ions from adhering to its surface during the electroplating process and affecting the subsequent use effect.

[0032] like Figure 4, to solve the problem of fixing plate parts.

[0033] A slider 203 is detachably connected to one end of the outer side of each clamp 201 , and two springs 204 are fixedly connected between the two sliders 203 of each clamping mechanism 12 , and the springs 204 are compression springs.

[0034] When clamping a plate-like part, the spring 204 is a compression spring, and the two rubber clamps 205 contact each other. When the clamping mechanism 12 fixes the part, first press one end of the clamp 201 at the slider 203, so that the two sliders 203 are relatively close to each other. At the same time, the spring 204 is compressed, and the clamp 201 rotates, thereby separating one end of the rubber clamps 205 from each other. Then, place the plate-like part between the two rubber clamps 205, release one end of the slider 203, and the compressed spring 204 pushes the two clamps 201 to rotate, so that the two rubber clamps 205 are close to fix the part.

[0035] like Figure 4 , to solve the problem of fixing shell-shaped parts.

[0036] The spring 204 is a tension spring.

[0037] Since the outer surfaces of some parts, such as rotary switches, need to be plated and thus cannot be fixed from the outside, when processing such parts, the spring 204 between the two sliders 203 is replaced with a tension spring, so that the two rubber clamps 205 are in a separated state. At this time, one end of the clamp 201 at the slider 203 is pushed, and the spring 204 is compressed, so that the two sliders 203 are relatively separated, and then one end of the two rubber clamps 205 are relatively close, and then the part is placed so that the rubber clamp 205 is located on the inside of the part, and then the compressed spring 204 is released, so as to push the slider 203.

[0038] The movable clamp 201 rotates to separate the two rubber clamps 205, thereby fixing the parts from the inside.

[0039] like Figure 5 , in order to solve the problem of the rotation of the longitudinal rod 101.

[0040] A rotating shaft 13 is rotatably connected to the carriage 11 , and a belt transmission is provided between the rotating shaft 13 and a longitudinal rod 101 .

[0041] After the slide 11 is moved so that it is located above the electroplating solution, the slide 11 is moved downward, thereby driving the longitudinal rod 101 to be immersed in the electroplating solution. At this time, the rotating shaft 13 moves downward with the slide 11, and then the rotating shaft 13 is rotated, thereby driving the longitudinal rod 101 to rotate through the belt and pulley, and then driving the cross bar 103 to rotate synchronously with the longitudinal rod 101 on the other side, so that the parts rotate in the electroplating solution.

[0042] like Figure 6 , to solve the problem of rotation of the rotating shaft 13.

[0043] The lifting frame 304 is rotatably connected with a driving shaft 303, the driving shaft 303 is provided with a convex key, and the second gear 302 is provided with a keyway, and the two are slidably connected. The first gear 301 is welded on the rotating shaft 13, and the first gear 301 and the second gear 302 are meshed with each other.

[0044] Initially, the lifting frame 304 is in a raised state, at which time the parts are fixed in the clamping mechanism 12, and then the lifting frame 304 is moved downward, thereby driving the drive shaft 303 to move, thereby causing the slide 11 to partially move downward and immerse it in the electroplating solution, and the second gear 302 is rotatably connected to the inside of the slide 11. When the slide 11 moves, it drives the second gear 302 to slide synchronously with the slide 11 on the drive shaft 303, so that the first gear 301 and the second gear 302 are always in a meshing state, driving the drive shaft 303 to rotate, and then driving the second gear 302 to rotate through the cooperation of the convex key and the keyway, thereby meshing and driving the first gear 301 to rotate, and then driving the rotating shaft 13 to rotate.

[0045] like Figure 7 and Figure 8 , to solve the problem of movement of the slide 11.

[0046] A chain conveyor 305 is provided on the lifting frame 304 , a driving block 306 is fixedly connected to the chain conveyor 305 , a driving plug plate 307 is slidably connected to the driving block 306 , and the driving plug plate 307 is in contact with the slide 11 .

[0047] When the driving chain conveyor 305 is working, the driving block 306 is driven to move, and then the driving plug plate 307 is driven to move, and then the slide 11 is pushed to slide along the driving shaft 303. When large-scale processing is performed, multiple groups of slide 11 parts and multiple groups of electroplating liquid are set, and driving blocks 306 and driving plug plates 307 corresponding to the number of slides 11 are set at the same time, so that multiple driving blocks 306 can simultaneously drive multiple slides 11 to move. After the parts are fixed from one side of the chain conveyor 305, the slide 11 is moved to the top of the electroplating liquid through the chain conveyor 305, and then the lifting frame 304 is moved downward. After the electroplating is completed, the lifting frame 304 is moved upward, and the chain conveyor 305 is driven to work to achieve the purpose of continuous processing.

[0048] like Fig. 9 , in order to solve the problem of the plating liquid being stirred and overflowing when the parts rotate in the plating liquid.

[0049] A plating liquid tank 14 is disposed below the lifting frame 304 . Blocking bars 401 are disposed around the inner wall of the plating liquid tank 14 . A blocking block 402 is fixedly connected to the lower surface of the inner part of the plating liquid tank 14 .

[0050] The plating liquid is placed in the plating liquid tank 14. When the longitudinal rod 101 and the transverse rod 103 rotate in the plating liquid tank 14, the plating liquid inside will be stirred, which may easily cause the plating liquid to vibrate and overflow from the plating liquid tank 14. The blocking blocks 402 and the blocking bars 401 in the plating liquid tank 14 can block the flow of the plating liquid when it is stirred, reduce the turbulence intensity, release the energy of the plating liquid when it is stirred, and reduce the shaking of the liquid surface, thereby preventing the liquid from overflowing from the plating liquid tank 14.

[0051] like Fig. 9 , in order to solve the problem of internal energy release when plating solutions of different densities are stirred.

[0052] One side of the blocking block 402 close to the slide 11 is configured as an arc surface, and each blocking block 402 is detachably connected to the electroplating liquid tank 14 .

[0053] When the part rotates in the plating liquid, the liquid below is pushed to one side, and the part of the blocking block 402 close to the slide 11 needs to be set to an arc surface to slowly reduce the energy of the plating liquid flow and avoid the liquid from flowing in the opposite direction after the plating liquid collides with the plane, thereby causing the two oppositely moving liquids to collide with each other, and then the liquid moves upward at the collision point, causing the liquid surface to shake more, thereby causing the liquid to overflow. The blocking block 402 and the plating liquid tank 14 are detachably connected, so that it is convenient to replace the blocking block 402 with different arc surface curvatures according to the density of the plating liquid. When the liquid density is large, the resistance when the part rotates is greater, and the energy transmitted to the plating liquid is greater. At this time, the blocking block 402 with a slower arc surface curvature should be replaced to slowly release the internal energy, and vice versa.

[0054] like Fig.10 , an electroplating equipment method used in an electroplating equipment, comprising the following steps:

[0055] S1: Fix the electroplated parts on the clamping mechanism 12;

[0056] S2: Install the blocking blocks 402 with different arc curvatures according to the required plating liquid. The greater the density of the plating liquid, the smaller the arc curvature, and vice versa, so as to release the energy of the plating liquid when it is stirred and avoid overflow of the plating liquid;

[0057] S3: driving the chain conveyor 305 to drive the slide 11 to the top of the electroplating liquid tank 14;

[0058] S4: driving the lifting frame 304 to move downward until the parts are completely immersed in the electroplating liquid tank 14, and then driving the driving shaft 303 to rotate to perform the electroplating work.
