Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to a spot plating device with adjustable spacing between single and dual nozzles. Background Technology

[0002] In modern industrial production, spot plating technology is widely used in many fields such as electronics, machinery, and aerospace. It is used to perform localized electroplating on specific areas of workpieces to meet the functional and aesthetic requirements of products. In electroplating equipment, the nozzle is the core component for achieving precise plating, and its performance directly determines the quality and efficiency of the electroplating process.

[0003] However, most existing spot plating equipment uses a single, typically fixed, nozzle, which cannot be flexibly adjusted according to workpiece size. For small, precision electronic components, if the plating solution sprayed from the nozzle easily overlaps and accumulates on the component surface, it can lead to uneven plating thickness, localized excessive thickness, or even short circuits caused by the plating solution damaging the component. Excess plating solution residue can also affect the component's normal function and subsequent assembly. For large mechanical parts, if the plating solution sprayed from the nozzle is too dispersed, large areas of unplated areas can easily appear between the plating dots on the surface of the mechanical parts, resulting in incomplete and discontinuous plating layers that fail to form an effective protective layer. This leads to uneven plating, missed plating, and other problems, affecting product quality and production efficiency. Therefore, there is an urgent need for a single or dual-nozzle adjustable-gap spot plating equipment that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a single / dual nozzle adjustable spacing spot plating device. This device can position the workpiece according to its size and adjust the distance between the two nozzles during the positioning process to accommodate workpieces of different sizes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a single or dual nozzle adjustable spacing spot plating device, including a frame, a support plate installed on the frame, and a positioning and moving component, a spot plating component, and an adjustable spacing component installed on the support plate.

[0006] The positioning and moving component includes a base plate, on which an mounting plate is mounted. A first lead screw and a second lead screw are mounted on the mounting plate. The first lead screw and the second lead screw are respectively connected to a first motor and a second motor. A gear meshes between the first lead screw and the second lead screw. A transmission shaft passes through the gear. A rotating block is mounted on the transmission shaft. Connecting rods are hinged to the four corners of the rotating block. Positioning blocks are hinged to the connecting rods. A disc is mounted at the top of the transmission shaft. A linear through hole is provided on the disc. The positioning block is locked in the linear through hole of the disc.

[0007] The spot plating assembly includes a solution tank with two hoses connected to it, and each hose is connected to a universal nozzle.

[0008] The distance adjustment component includes a bracket, on which a slide bar is mounted, and on the slide bar are three sliders. The universal nozzle is fixedly mounted on the two side sliders, and a T-shaped plate is mounted below the two side sliders. A groove is provided on the positioning block, and the T-shaped plate is stuck in the groove.

[0009] Furthermore, the base plate is located below the support plate, and the mounting plate is vertically fixed at both ends of the base plate, with the mounting plate fixedly installed on the bottom surface of the support plate.

[0010] Furthermore, a rectangular through hole is provided on the support plate, the drive shaft passes through the support plate, and its two ends extend to the upper and lower sides of the support plate respectively. The gear is located at the lower end of the drive shaft and below the support plate, and the rotating block is located above the support plate.

[0011] Furthermore, the disk has a circular hole at its center, through which the drive shaft passes. Several rollers are mounted on the bottom surface of the disk, and a rectangular groove is provided on the surface of the support plate. The rollers are engaged in the rectangular groove, so the disk will not rotate, but it can move horizontally on the support plate.

[0012] Furthermore, the vertical surface of the through hole on the disk is provided with a protruding ridge, and the side surface of the positioning block is provided with a groove. The positioning block is locked in the through hole of the disk through the groove and can move along the length direction of the through hole.

[0013] Furthermore, the spot plating assembly includes an electrical control box, which is fixedly installed inside the frame and located above the support plate. The negative terminal of the electrical control box is connected to the electroplating workpiece via a wire, and the positive terminal of the electrical control box is connected to the electroplating pen via a wire.

[0014] Furthermore, a U-shaped plating pen holder is fixedly installed on the slider, and the plating pen is mounted on the plating pen holder. The plating pen can move vertically on the plating pen holder to adjust the distance between it and the disc.

[0015] Furthermore, the universal nozzle includes a base, which is connected to a hose. A ball joint is connected to the lower end of the base, and a matching nozzle is installed at the lower end of the ball joint. The nozzle can freely deflect at multiple angles within the ball joint.

[0016] Furthermore, a flat plate is fixedly installed at the bottom of the slider, and a straight groove is provided on the flat plate. A T-shaped plate is connected to the flat plate in a vertically inverted position. A threaded hole is provided at the top of the T-shaped plate, and the threaded hole is connected to the straight groove. A bolt is screwed between the threaded hole and the straight groove.

[0017] Compared with existing technologies, the advantages of this invention are as follows: The electroplated workpiece is placed in the center of a circular disc. By controlling one of the first and second lead screws to rotate while the other remains stationary, either the first or second lead screw drives a gear to rotate. The gear, through a transmission shaft, drives a rotating block to rotate. A connecting rod hinged between the rotating block and the positioning block then drives several positioning blocks to move synchronously towards the center, thus positioning the workpiece on the disc. During positioning, the positioning blocks can move via a T-shaped plate, allowing the spacing between the two universal nozzles to be adjusted according to the size of the electroplated product.

[0018] After positioning, the electroplating pen can be controlled via the electrical control box to electroplat the workpiece. By controlling the first and second lead screws to rotate at the same speed and in the same direction, the gear moves horizontally along with the rotation of the first and second lead screws, thereby driving the disc to move horizontally. The rollers on the bottom of the disc roll along the length of the rectangular groove, and the T-shaped plate moves horizontally along the slide. The electroplated product can sequentially pass through different areas below the electroplating pen, allowing the pen to electroplat various parts of the product's surface and ensuring a uniform metal layer. During the movement, the gears and rotating block do not rotate, and the electroplated workpiece remains in a positioned state.

[0019] This utility model equipment can position the workpiece according to its size and adjust the distance between the two nozzles during the positioning process, so that the electroplating solution is sprayed onto the workpiece surface more evenly. This avoids problems such as uneven electroplating and missed plating caused by inaccurate workpiece positioning or unsuitable nozzle distance, thereby improving the quality of electroplated products and enhancing their performance and appearance.

[0028] See Figure 1 As shown, the present invention provides a single or double nozzle adjustable spacing spot plating device, including a frame 101. The frame 101 is a rectangular frame structure. Support legs and casters are fixedly installed at the four corners of the bottom of the frame 101. A support plate 102 is horizontally fixedly installed in the middle of the frame 101.

[0029] See Figure 2-4As shown, a positioning and moving assembly, including a base plate 201, is installed on the support plate 102, located below the support plate 102. Mounting plates 202 are vertically fixed to both ends of the base plate 201, and are vertically fixed to the bottom surface of the support plate 102. A rotatable first lead screw 203 and a second lead screw 204 are mounted parallel between the two mounting plates 202, with one end of the first lead screw 203 and the second lead screw 204 respectively connected to a first motor 213 and a second motor 214. A gear 205 is provided between the first lead screw 203 and the second lead screw 204, meshing with each other, and a drive shaft 206 passes through the middle of the gear 205. A rectangular through hole is provided in the support plate 102, through which the drive shaft 206 passes, extending to the upper and lower sides of the support plate 102 respectively. Gear 205 is located at the lower end of drive shaft 206 and below support plate 102. A square rotating block 207 is fixedly installed on the upper end of drive shaft 206. Four L-shaped connecting rods 208 are hinged to the four corners of the square rotating block 207, and a positioning block 209 is hinged to the other end of each connecting rod 208. A disc 210 is installed at the top of drive shaft 206. During electroplating, the electroplated workpiece is placed on the disc 210.

[0030] It should be noted that a circular hole is provided in the center of the disc 210, through which the drive shaft 206 passes. The drive shaft 206 does not drive the disc 210 to rotate. Several linear through holes are provided on the surface of the disc 210, with protruding ridges on the vertical surfaces of the through holes. A groove is provided on the side surface of the positioning block 209. The positioning block 209 is engaged in the through holes of the disc 210 through the grooves and can move along the length of the through holes of the disc 210 via the grooves. Several rollers 211 are mounted on the bottom surface of the disc 210. A rectangular groove 212 is provided on the surface of the support plate 102, with the length of the rectangular through holes being the same as the length of the rectangular groove 212 on the surface of the support plate 102. The rollers 211 are engaged in the rectangular grooves 212 and can roll along the rectangular grooves 212. When the rollers 211 roll in the grooves, they drive the disc 210 to move horizontally on the plane of the support plate 102.

[0031] A spot plating assembly is mounted on the support plate 102. The spot plating assembly includes an electrical control box 301, which is fixedly installed inside the frame 101 and located above the support plate 102. The negative terminal of the electrical control box 301 is connected to the electroplating workpiece via a wire. The positive terminal of the electrical control box 301 is connected to the electroplating pen 302 via a wire. A solution tank 304 is mounted on the bottom surface of the frame 101. The solution tank 304 stores the solution required for electroplating. The solution tank 304 has two outlets, each connected to a flexible hose 305. The other end of each flexible hose 305 is connected to a universal nozzle. The universal nozzle includes a square base 306, which is mated to the flexible hose 305. The lower end of the base 306 is mated to a ball joint 307. A matching nozzle 308 is mounted on the lower end of the ball joint 307. The nozzle 308 can freely deflect at multiple angles within the ball joint 307.

[0032] See Figure 5 As shown, an adjustment assembly is provided on the support plate 102. The adjustment assembly includes two brackets 401 fixedly installed on the support plate 102, located on both sides of the support plate 102. A slide rod 402 is installed between the two brackets 401, and three freely sliding sliders 403 are installed on the slide rod 402. The slide rod 402 and the sliders 403 are located above the disc 210. Two universal nozzles are fixedly installed on the two side sliders 403 respectively. A U-shaped plating pen holder 303 is fixedly installed on the middle slider 403. The plating pen 302 is installed on the plating pen holder 303, and the plating pen 302 moves vertically on the plating pen holder 303 to adjust the distance between itself and the disc 210. It should be noted that the movement range of the slider on which the plating pen 302 is installed is limited to the two sliders 403 equipped with universal nozzles, and the position adjustment of this slider must be completed manually. The distance between the electroplating pen 302 and the disc 210 needs to be manually adjusted in the plating pen holder 303.

[0033] A flat plate 405 is fixedly installed at the bottom of the sliders 403 on both sides. A straight groove is provided on the flat plate 405. A T-shaped plate 404 is installed below the flat plate 405. The T-shaped plate 404 is connected to the flat plate 405 in a vertically inverted position. A threaded hole is provided on the top surface of the inverted T-shaped plate 404. The threaded hole aligns with the straight groove. A bolt 406 is screwed between the threaded hole and the straight groove. When the bolt 406 is tightened, the T-shaped plate 404 can be fixed on the flat plate 405. The position of the T-shaped plate 404 can be adjusted horizontally with respect to the straight groove via the bolt 406. A sliding groove is provided on the positioning blocks 209 on both sides of the disc 210. The horizontal base plate 201 of the inverted T-shaped plate 404 is engaged in the sliding groove and can move horizontally along the sliding groove.

[0034] Example: When one of the first lead screw 203 and the second lead screw 204 rotates while the other does not, either the first lead screw 203 or the second lead screw 204 will drive the gear 205 to rotate. The gear 205 drives the rotating block 207 to rotate via the transmission shaft 206. Through the connecting rod 208 hinged between the rotating block 207 and the positioning block 209, the gear 205 drives several positioning blocks 209 to move synchronously on the surface of the disc 210. When the positioning blocks 209 move synchronously towards the center, they can clamp the workpiece placed on the disc 210. When the positioning blocks 209 move in the opposite direction, they can release the workpiece placed on the disc 210. During the positioning process of the spot-plated workpiece, the positioning blocks 209 can drive the slider 403 to move via the T-shaped plate 404, thereby adjusting the spacing of the universal nozzles installed on the slider 403 according to the size of the electroplated workpiece.

[0035] After positioning, the electroplating pen 302 can be controlled by the electrical control box 301 to electroplat the workpiece. When the first lead screw 203 and the second lead screw 204 rotate at the same speed and in the same direction, the gear 205 is subjected to a force of equal magnitude and in the same direction. At this time, the gear 205 and its connected transmission shaft 206 will not rotate, but will move horizontally with the rotation of the first lead screw 203 and the second lead screw, thereby driving the disc 210 to move horizontally along the length of the support plate 102. The roller 211 on the bottom surface of the disc 210 rolls along the length of the rectangular groove 212, and the T-shaped plate 404 moves horizontally along the slide groove. The electroplated workpiece placed on the disc 210 moves horizontally below the electroplating pen 302. The electroplated workpiece can pass through different areas below the electroplating pen 302 in sequence, so that the electroplating pen 302 can electroplat various parts of the surface of the electroplated workpiece and ensure that the surface of the electroplated workpiece is uniformly plated with a metal layer. During the horizontal movement of the disc 210, the rotating block 207 fixed to the upper end of the drive shaft 206 will not rotate, the connecting rod 208 hinged to the four corners of the rotating block 207 will not swing, and the positioning block 209 will not move within the through hole of the disc 210, so the electroplated workpiece is in a positioning state.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
