Description

Technical Field

[0001] The present invention relates to the technical field of electroplating devices, and in particular to an electroplating device and method for surface treatment of metal products. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on the metal surface. It is an important surface treatment technology. The main functions of electroplating include anti-corrosion, beautification, improving wear resistance, environmental protection, etc. Different metal products require different electroplating treatments depending on the application scenarios or uses of the product.

[0003] At present, the existing electroplating device mainly includes an electroplating tank and an electroplating rack. Specifically, during the electroplating process, the staff needs to place the workpiece on the electroplating rack, and then connect the electroplating rack to the negative pole of the power supply, that is, connect the workpiece to the negative pole of the power supply, and then put the electroplating rack into the electroplating solution for immersion. After a period of time, take out the electroplating rack to complete the electroplating process. However, in the actual electroplating process, we often need to transfer the workpiece in multiple electroplating tanks. For example, by transferring the workpiece from a plating solution of one concentration to another concentration of the plating solution, the concentration of the plating solution can be adjusted to meet the electroplating requirements of different stages, thereby helping to ensure the deposition quality and uniformity of the workpiece surface to obtain a better electroplating effect. Sometimes, the electroplated parts need to be subjected to multi-layer electroplating, that is, different coatings are formed in different electroplating solutions. This multi-layer electroplating can give the electroplated parts more properties, such as corrosion resistance, wear resistance, etc. In order to achieve multi-layer electroplating, the electroplated parts need to be transferred in different electroplating solutions so as to form the required coating in each electroplating solution.

[0004] Nowadays, in the actual electroplating process, when the electroplated parts need to be transferred in multiple electroplating solutions, it is often inevitable that the electroplating solution in the previous electroplating tank will remain on the surface of the electroplated parts, and these residual liquids will be brought into the next electroplating tank as the electroplated parts move. This not only reduces the purity and electroplating effect of the electroplating solution in the next electroplating tank, but also increases the cost of maintaining the electroplating solution, which has obvious shortcomings. In order to overcome this drawback, in the prior art, the invention patent with publication number CN113913883B proposes an electroplating device, which includes a first electroplating tank, a second electric tank, a conveying device, a flushing mechanism and a drying mechanism. After the electroplating of the electroplated parts in the first electroplating tank is completed, the conveying device needs to carry the workpiece into the flushing mechanism, and then the flushing mechanism starts to perform preliminary flushing on the electroplated parts; after the flushing is completed, the drying mechanism blows air again to air-dry the electroplated parts, and finally, the conveying device carries the electroplated parts to the second electroplating tank for secondary electroplating.

[0005] In order to overcome the cross-contamination between different electroplating solutions, the above invention patent uses flushing and drying to clean the electroplated parts. However, since the flushing mechanism and the drying mechanism are both located outside the first electroplating tank, when the electroplated parts are taken out of the first electroplating tank for transfer, it is inevitable that the electroplating solution will drip outside the electroplating tank, thereby causing pollution to the external environment and increasing the cleaning burden. To this end, we propose an electroplating device and method for surface treatment of metal products to effectively solve the above-mentioned drawbacks. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figure 1 - Fig.13 A plating device for surface treatment of metal products includes a plating pool 100, wherein a plurality of partitions 101 are arranged inside the plating pool 100, and the plurality of partitions 101 divide the internal space of the plating pool 100 into a plurality of plating tanks. Specifically, in the present embodiment, each plating tank is not interconnected, and each plating tank can be filled with different plating solutions, so as to meet different plating requirements of workpieces. A bracket 102 is arranged on the top of the plating pool 100, and the bracket 102 is in the shape of a gate. A first linear slide 103 is arranged on the top of the bracket 102 along its length direction, and a vertical plate 200 is arranged on the movable end of the first linear slide 103, and a second linear slide 201 is arranged vertically on the surface of the vertical plate 200, and a horizontal plate 300 is arranged on the movable end of the second linear slide 201. Therefore, the first linear slide 103 can control the lateral movement of the vertical plate 200, and the second linear slide 201 can control the longitudinal movement of the horizontal plate 300.

[0044] Furthermore, a mounting plate 301 is provided on the surface of the horizontal plate 300, and a blowing portion 302 is provided at the bottom end of the horizontal plate 300. Figure 6As shown, the blowing portion 302 is an internal hollow structure, a through hole 303 is opened in the middle position of the blowing portion 302, a plurality of nozzles 304 are provided on the bottom surface of the blowing portion 302, an air pump 305 is provided on the top surface of the blowing portion 302, and the air outlet end of the air pump 305 is communicated with the interior of the blowing portion 302; that is, the top surface of the blowing portion 302 has an air inlet, and the air outlet end of the air pump 305 extends into the air inlet. When the air pump 305 is turned on, external gas can be blown into the blowing portion 302, and finally the gas is ejected downward from the nozzle 304.

[0045] like Figure 4 As shown, the surface of the mounting plate 301 is provided with an extension platform 306, and the extension platform 306 is distributed in the horizontal direction. The electroplating rack 400 is fixedly provided on the extension platform 306. The bottom of the electroplating rack 400 passes through the through-hole 303 and extends to the bottom of the blowing part 302; the electroplating rack 400 includes a vertical rod 401, a first cross bar 402 and a second cross bar 403. The vertical rod 401 passes through the extension platform 306 and is fixedly connected to the extension platform 306. The bottom end of the vertical rod 401 is connected to the middle section of the first cross bar 402. There are a plurality of second cross bars 403, and the plurality of second cross bars 403 all pass through the first cross bar 402. Both ends of the second cross bar 403 are provided with an arch-shaped Hook 404; a conductive rod 405 is inserted into the interior of the vertical rod 401, the top of the conductive rod 405 extends above the vertical rod 401, and several hooks 404 are electrically connected to the conductive rod 405; the hook 404 and the conductive rod 405 are both made of copper material, specifically, the vertical rod 401, the first cross bar 402 and the second cross bar 403 are all hollow tubular structures, the hook 404 is a copper wire, the inner end of the hook 404 extends into the second cross bar 403, the first cross bar 402 and the vertical rod 401 and is connected to the conductive rod 405, and the ends of the vertical rod 401, the first cross bar 402 and the second cross bar 403 are all sealed to prevent the electroplating solution from entering the interior of the rod body.

[0046] It should be noted that, in this embodiment, the hook 404 is in an upwardly curved arch shape, and the hook 404 is mainly used to fix a cylindrical workpiece, such as Figure 4 As shown, since the hook 404 has a certain elasticity, the workpiece can be covered on the outside of the hook 404 from top to bottom, and then both ends of the hook 404 can abut against the inner wall of the workpiece, thereby fixing the position of the workpiece.

[0047] In addition, a positioning block 202 is provided at the movable end of the second linear slide 201. Fig.11As shown, a hinge seat 203 is provided on the surface of the positioning block 202, and the cross plate 300 is rotatably connected to the hinge seat 203. A return spring 204 is also connected between the cross plate 300 and the positioning block 202. In a natural state, the cross plate 300 and the positioning block 202 are distributed in parallel; the two ends of the return spring 204 are respectively fixedly connected to the cross plate 300 and the positioning block 202, and the return spring 204 is in a compressed state. Since the elastic forces of the two return springs 204 offset each other, the cross plate 300 and the positioning block 202 are parallel in a natural state.

[0048] The horizontal plate 300 is symmetrically provided with protrusions 307 on both sides of the side facing the vertical plate 200. Figure 5 As shown, the left and right sides of the surface of the vertical plate 200 are respectively provided with a first stopper 205 and a second stopper 206. Figure 3 As shown, the first blocking block 205 and the second blocking block 206 are staggered in the upper and lower parts, and both of the first blocking block 205 and the second blocking block 206 are semicircular in shape. When the cross plate 300 moves to a position directly opposite to the first blocking block 205 and the second blocking block 206, the two protrusions 307 will collide with the first blocking block 205 and the second blocking block 206 respectively; therefore, in the process of the cross plate 300 moving upward, due to the existence of the two first blocking blocks 205 and the second blocking block 206, the cross plate 300 can swing back and forth, thereby helping to quickly get rid of the plating liquid on the surface of the electroplated workpiece.

[0049] It should be noted that when the horizontal plate 300 moves to a position facing the first blocking block 205 and the second blocking block 206, the electroplating rack 400 has completely risen to the top of the electroplating tank. At this time, with the collision between the protrusion 307 and the first blocking block 205 and the second blocking block 206, the horizontal plate 300 can swing back and forth rapidly, and due to inertia, the plating liquid on the surface of the electroplated workpiece can be shaken off.

[0050] In addition, a main shaft 308 is provided on the side of the mounting plate 301 facing the horizontal plate 300. Figure 7 As shown, a shaft hole 309 is formed through the middle of the horizontal plate 300. Figure 6 As shown, the main shaft 308 is rotatably connected to the shaft hole 309 through a bearing, so the mounting plate 301 can rotate around the main shaft 308; the left and right ends of the cross plate 300 are symmetrically provided with first pull rods 310, and the left and right ends of the mounting plate 301 are symmetrically provided with second pull rods 311, and tension springs 312 are connected between the first pull rods 310 and the corresponding second pull rods 311. In the natural state, the two tension springs 312 are in a stretched state, so the mounting plate 301 is in a horizontal posture.

[0051] Furthermore, the left and right sides of the top of the horizontal plate 300 are respectively provided with a first electromagnet 313 and a second electromagnet 314, the mounting plate 301 is made of iron material, the top surface of the extension platform 306 is provided with a power supply 500, and the power supply 500 is electrically connected to the first electromagnet 313 and the second electromagnet 314. When the first electromagnet 313 is energized, the mounting plate 301 is in a posture of being higher on the left and lower on the right, as shown in FIG. Fig. 9 As shown, the left end of the mounting plate 301 abuts against the first electromagnet 313; when the second electromagnet 314 is energized, the mounting plate 301 is in a posture with the left side lower and the right side higher, as shown in FIG. Fig.10 As shown, the right end of the mounting plate 301 abuts against the second electromagnet 314; that is, the magnetic attraction of the first electromagnet 313 and the second electromagnet 314 on the mounting plate 301 can overcome the tension of the tension spring 312 to rotate the mounting plate 301.

[0052] Conductive sheets 207 are symmetrically arranged on the left and right sides of the top of the vertical plate 200. Figure 7 As shown, the two conductive sheets 207 are connected to the positive and negative electrodes of the power source 500 respectively, and the first conductive posts 315 are symmetrically arranged on the left and right sides of the side of the horizontal plate 300 facing the vertical plate 200, and the second conductive posts 316 are also arranged below the first conductive posts 315. The two leads of the first electromagnet 313 are connected to the two first conductive posts 315 respectively, and the two leads of the second electromagnet 314 are connected to the two second conductive posts 316 respectively; when the two first conductive posts 315 are respectively in contact with the two conductive sheets 207, the first conductive posts 315 are connected to the two conductive sheets 207. An electromagnet 313 is energized, and when the two second conductive pillars 316 are respectively in contact with the two conductive sheets 207, the second electromagnet 314 is energized; specifically, the conductive sheet 207 is made of copper sheet, and the first conductive pillar 315 and the second conductive pillar 316 are made of copper pillars, and the connection between the conductive sheet 207 and the vertical plate 200 is insulated to prevent the vertical plate 200 from leaking electricity, and the connection between the first conductive pillar 315 and the second conductive pillar 316 and the horizontal plate 300 is also insulated to prevent the horizontal plate 300 from leaking electricity.

[0053] In addition, arc strips 317 are symmetrically arranged on the left and right sides of the surface of the horizontal plate 300, and track grooves 318 are opened on the surface of the arc strips 317. Fig.12 As shown, the center of the circle corresponding to the track groove 318 coincides with the center of the circle of the main shaft 308, and two limiting columns 319 are provided on the back of the mounting plate 301, and the two limiting columns 319 are respectively inserted into the two track grooves 318; one of the track grooves 318 has first conductive contacts 320 at both ends, and the other track groove 318 has second conductive contacts 321 at both ends, and the first conductive contacts 320 and the second conductive contacts 321 are respectively connected to the positive and negative electrodes of the power supply 500, and the head of the limiting column 319 is provided with a conductive plug 322, and the two conductive plugs 322 are respectively connected to the two leads of the air pump 305, as shown in FIG. Fig.13As shown; when the first electromagnet 313 or the second electromagnet 314 is energized, the two conductive plugs 322 are in contact with the corresponding first conductive contact 320 and the second conductive contact 321 respectively; the arc strip 317 is made of insulating material, such as plastic, to avoid leakage, and the limiting column 319 is also made of insulating material; when the two conductive plugs 322 are in contact with the first conductive contact 320 and the second conductive contact 321 respectively, the air pump 305 is energized and works.

[0054] Embodiment 2: This embodiment of the present application provides an electroplating method for surface treatment of metal products, which is applicable to the electroplating device in Embodiment 1, and comprises the following steps:

[0055] Fix a plurality of workpieces with the electroplating rack 400, and then use the second linear slide 201 to control the electroplating rack 400 to descend into the corresponding electroplating tank;

[0056] After a period of electroplating, the second linear slide 201 is used to control the electroplating hanger 400 to rise, so that the tool is separated from the electroplating solution;

[0057] When the horizontal plate 300 rises to a position facing the first stopper 205 and the second stopper 206, the horizontal plate 300 can be quickly swung back and forth, thereby helping to shake off the electroplating liquid on the surface of the workpiece;

[0058] When the horizontal plate 300 rises until the two first conductive pillars 315 are in contact with the conductive sheet 207, the second linear slide 201 stops moving. At this time, the first electromagnet 313 is energized, the mounting plate 301 is tilted with the left side higher than the right side, and the air pump 305 is energized to work, and the nozzle 304 blows air downward, thereby accelerating the dripping of the electroplating liquid on the surface of the workpiece;

[0059] After a period of time, the second linear slide 201 continues to drive the electroplating rack 400 to rise until the two second conductive pillars 316 are in contact with the conductive sheet 207. At this time, the second electromagnet 314 is energized, the mounting plate 301 is tilted with the left side lower and the right side higher, and the air pump 305 is still powered on to further accelerate the drying of the workpiece.

[0060] After blowing for a period of time, the first linear slide 103 is used to control the electroplating rack 400 to move horizontally to the top of the adjacent electroplating tank, and the above steps are repeated until the electroplating rack 400 is immersed in all the electroplating tanks; specifically, when there is no more electroplating liquid dripping on the surface of the electroplated part, the first linear slide 103 controls the electroplating rack 400 to move horizontally, and the second linear slide 201 controls the electroplating rack 400 to be immersed in another electroplating liquid.
