It includes an electroplating tank with a protective cover fixedly connected to its top. The protective cover is equipped with a lifting mechanism, and the electroplating tank has two agitation mechanisms. Two driven rods are rotatably connected to the inner cavity of the electroplating tank, and two driving rods are rotatably connected to the inner cavity of the protective cover. In this utility model, by setting a protective cover above the electroplating tank, the electroplating solution is prevented from splashing out and posing a danger to workers lifting parts. Furthermore, a first motor drives the driving rods and an arc-grooved wheel to rotate, and the arc-grooved wheel drives the steel wire rope and the clamps and hanging rings on the steel wire rope to rotate synchronously. This allows parts to be hoisted onto the hanging rings from the lower part of one end of the protective cover via hooks. The steel wire rope then moves the parts to the inner cavity of the electroplating tank for electroplating, eliminating the need to hoist parts from the side of the electroplating tank, thus improving safety.

Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and more specifically, to a full-coverage electroplating device. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation and improving wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics. During electroplating, the electroplating tank contains an electroplating solution, which is mainly classified into four categories based on its composition: cyanide zinc plating, zincate zinc plating, chloride zinc plating, and sulfate zinc plating. Cyanide zinc plating solutions contain highly toxic cyanide, and sulfate zinc plating is corrosive. Most existing electroplating tanks have an open top structure, posing certain dangers to workers during material hanging and retrieval. Furthermore, the hooks used to hang parts have a certain contact area with the parts, which is difficult to electroplat, affecting the plating quality. Therefore, we propose a fully covered electroplating device. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a full-coverage electroplating equipment.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A fully enclosed electroplating device includes an electroplating tank. A protective cover is fixedly connected to the top of the electroplating tank. A lifting mechanism is provided on the protective cover. Two agitation mechanisms are provided on the electroplating tank. Two driven rods are rotatably connected to the inner cavity of the electroplating tank. Two driving rods are rotatably connected to the inner cavity of the protective cover. Arc-grooved wheels are fixedly sleeved on the two driving rods and the two driven rods respectively. A steel wire cable is driven between the four arc-grooved wheels. Multiple clips are fixedly sleeved on the outer side of the steel wire cable. Each of the multiple clips is fixedly connected to a hanging ring. A hook is sleeved on the hanging ring. A first motor is fixedly installed on the back of the protective cover. The output shaft of the first motor is connected to the end of a driving rod through a coupling.

[0006] As a preferred embodiment of this utility model, the lifting mechanism includes an electric telescopic rod fixedly installed on the top surface of the protective cover. The output end of the electric telescopic rod extends into the inner cavity of the protective cover and is fixedly connected to a connecting column via a coupling. The bottom end of the connecting column extends into the inner cavity of the electroplating tank and is fixedly connected to a lifting mesh plate.

[0007] As a preferred embodiment of the present invention, the agitation mechanism includes a second motor fixedly installed on the back of the electroplating tank. The output shaft of the second motor extends into the inner cavity of the electroplating tank and is fixedly connected to an agitator rod via a coupling. Multiple agitator plates are fixedly connected to the outer side of the agitator rod.

[0008] As a preferred embodiment of this utility model, a DC power supply is provided on the back of the protective cover. Both the positive and negative terminals of the DC power supply are fixedly connected to wires. One end of the wire is fixedly connected to a conductive rod. The end of the conductive rod is fixedly sleeved into the inner cavity of the protective cover and in contact with the inner side of the steel wire cable. The other end of the wire is fixedly connected to an anode electroplating rod. The end of the anode electroplating rod is fixedly sleeved into the inner cavity of the electroplating tank.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed on the outer side of the protective cover, and the control panel is electrically connected to the first motor, the second motor, and the electric telescopic rod respectively.

[0010] In a preferred embodiment of this utility model, the steel wire rope, the sleeve, the hanging ring, and the hook are all made of conductive materials, and the arc grooved wheel is made of insulating material.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] (1) In this utility model, by setting a protective cover above the electroplating tank, the electroplating liquid is prevented from splashing out and causing danger to the workers who hoist the parts. In addition, the first motor drives the active rod and the arc groove wheel to rotate, and the arc groove wheel drives the steel wire rope and the clamp and hanging ring on the steel wire rope to rotate synchronously, so that the parts can be hoisted on the hanging ring from the lower part of one end of the protective cover through the hook. The steel wire rope is used to move the parts to the inner cavity of the electroplating tank for electroplating. There is no need to hoist the parts on the side of the electroplating tank, which is safe.

[0013] (2) In this utility model, when the part is driven by the hook to fully enter the electroplating solution in the inner cavity of the electroplating tank, the electric telescopic rod is used to drive the connecting column and the lifting mesh plate to move up. The lifting mesh plate is used to push the part suspended on the hook upward a certain distance, so that the contact part between the hook and the part is separated, so that the part can also be electroplated, ensuring that the part can be fully electroplated, which is practical.

[0024] Example:

[0025] Please see Figure 1-5 A fully covered electroplating device includes an electroplating tank 1, a protective cover 2 fixedly connected to the top of the electroplating tank 1, a lifting mechanism 4 provided on the protective cover 2, two agitation mechanisms 3 provided on the electroplating tank 1, two driven rods 6 rotatably connected to the inner cavity of the electroplating tank 1, two driving rods 5 rotatably connected to the inner cavity of the protective cover 2, arc grooved wheels 7 fixedly sleeved on the two driving rods 5 and the two driven rods 6 respectively, steel wire ropes 8 are connected between the four arc grooved wheels 7, multiple clips 9 are fixedly sleeved on the outer side of the steel wire ropes 8, each clip 9 is fixedly connected to a hanging ring 10, and a hook 11 is sleeved on the hanging ring 10, a first motor 23 is fixedly installed on the back of the protective cover 2, and the output shaft of the first motor 23 is connected to the end of a driving rod 5 through a coupling.

[0026] In this embodiment, the top of the electroplating tank 1 is protected by the protective cover 2 to avoid the danger of directly taking the electroplated parts from the top of the electroplating tank 1. In addition, there is a certain friction between the arc groove wheel 7 and the steel wire rope 8 to ensure smooth transmission between the arc groove wheel 7 and the steel wire rope 8.

[0027] For details, please refer to Figure 1 and Figure 3 The lifting mechanism 4 includes an electric telescopic rod 12 fixedly installed on the top surface of the protective cover 2. The output end of the electric telescopic rod 12 extends into the inner cavity of the protective cover 2 and is fixedly connected to a connecting column 13 via a coupling. The bottom end of the connecting column 13 extends into the inner cavity of the electroplating tank 1 and is fixedly connected to a lifting mesh plate 14.

[0028] In this embodiment, the electric telescopic rod 12 drives the connecting column 13 and the lifting mesh plate 14 to move up and down. The lifting mesh plate 14 in the inner cavity of the electroplating tank 1 supports the bottom of the part that enters the inner cavity of the electroplating tank 1 and causes the part to move upward a certain distance, so that the hook 11 and the lifting contact part on the part are separated, so that the contact part between the hook 11 and the lifting part of the part can be electroplated.

[0029] For details, please refer to Figure 2 and Figure 3 The stirring mechanism 3 includes a second motor 15 fixedly installed on the back of the electroplating tank 1. The output shaft of the second motor 15 extends into the inner cavity of the electroplating tank 1 and is fixedly connected to a stirring rod 16 via a coupling. Multiple stirring plates 17 are fixedly connected to the outer side of the stirring rod 16.

[0030] In this embodiment, the second motor 15 drives the stirring rod 16 and the stirring plate 17 to rotate. The stirring plate 17 stirs the electroplating solution in the inner cavity of the electroplating tank 1 so that the cations can be successfully electroplated onto the parts.

[0031] For details, please refer to Figure 2 and Figure 3A DC power supply 18 is provided on the back of the protective cover 2. The positive and negative terminals of the DC power supply 18 are fixedly connected to wires 19. A conductive rod 20 is fixedly connected to the end of one wire 19. The end of the conductive rod 20 is fixedly sleeved into the inner cavity of the protective cover 2 and in contact with the inner side of the steel wire cable 8. An anode electroplating rod 21 is fixedly connected to the end of the other wire 19. The end of the anode electroplating rod 21 is fixedly sleeved into the inner cavity of the electroplating tank 1.

[0032] In this embodiment, the conductive rod 20 is connected to the negative terminal of the DC power supply 18, and the anode electroplating rod 21 is connected to the positive terminal of the DC power supply 18. The anode electroplating rod 21 can be made of metal zinc, metal nickel, etc.

[0033] For details, please refer to Figure 1 and Figure 2 A control panel 22 is fixedly installed on the outside of the protective cover 2. The control panel 22 is electrically connected to the first motor 23, the second motor 15, and the electric telescopic rod 12.

[0034] In this embodiment, the control panel 22 is used to control the first motor 23, the second motor 15, and the electric telescopic rod 12, and the power supply of the control panel 22, the first motor 23, the second motor 15, and the electric telescopic rod 12 is used. This is prior art and will not be described in detail.

[0035] For details, please refer to Figure 3 The steel wire rope 8, the sleeve 9, the hanging ring 10 and the hook 11 are all made of conductive material, while the arc groove wheel 7 is made of insulating material.

[0036] In this embodiment, the steel wire rope 8, the sleeve 9, the hanging ring 10 and the hook 11 are ensured to conduct electricity smoothly, so that the parts hoisted by the hook 11 can act as the cathode for electroplating, allowing cations to adhere to their surfaces.

[0037] Working principle: In use, the first motor 23 is started first, driving an active rod 5 and an arc-grooved wheel 7 to rotate clockwise. The arc-grooved wheel 7 drives the steel wire rope 8 and the clamp 9 and hanging ring 10 on the steel wire rope 8 to rotate synchronously. At the same time, the two second motors 15 are started, driving the two stirring rods 16 and multiple stirring plates 17 to rotate. The stirring plates 17 are used to stir the electroplating solution in the inner cavity of the electroplating tank 1. Then, the hook 11 is used to hook the metal parts, and the top of the hook 11 is hung on the hanging ring 10 below the steel wire rope 8, so that the parts follow the steel wire rope 8 to move into the electroplating inner cavity of the electroplating tank 1. The parts are electroplated in the electroplating solution. Then, the electric telescopic rod 12 is activated to move the connecting column 13 and the lifting mesh plate 14 upward. The lifting mesh plate 14 pushes the parts suspended on the hook 11 upward a certain distance, so that the contact part between the hook 11 and the parts is separated, so that the parts can also be electroplated. In addition, it ensures that the parts will not fall off the hook 11, so that the parts can continue to move with the steel wire cable 8. Finally, the electroplated parts are lifted upward with the steel wire cable 8, so that the electroplated parts are taken out from the electroplating solution in the inner cavity of the electroplating tank 1, so that the electroplated parts can be removed.

[0038] When the part is moved onto the electroplating solution inside the electroplating tank 1, the part is made into a cathode by means of wire 19, conductive rod 20, steel wire cable 8, clip 9, hanging ring 10 and hook 11. The anode electroplating rod 21 is dissolved by means of another wire 19 and anode electroplating rod 21, so that the cations are reduced on the surface of the part to form a plating layer.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
