Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, in particular to an electroplating device. Background Art

[0002] Electroplating is a process that coats a metal surface with a layer of metal or alloy through electrolysis. During the electroplating process, proper stirring and shaking are required to prevent bubbles generated during the electroplating process from adhering to the surface of the workpiece, resulting in uneven coating. Stirring and shaking can also speed up production efficiency.

[0003] For example, Chinese utility model patent publication number CN221398144U discloses a curved oscillating device for electroplating. The oscillating device is provided with a lateral oscillating mechanism and a longitudinal oscillating mechanism in cooperation with each other, which can drive a conductive rod to move back and forth in the horizontal direction and to move up and down in the vertical direction, thereby allowing a workpiece suspended on the conductive rod to repeatedly enter the electroplating solution, thereby improving the electroplating effect.

[0004] However, when the above-mentioned swing device is actually operated, although the placement frame can achieve reciprocating translation in the horizontal direction and reciprocating lifting and lowering in the vertical direction with the cooperation of the horizontal swing mechanism and the longitudinal swing mechanism, as a whole, the workpiece on the placement frame only moves within the two-axis plane, which makes the stirring of the plating solution insufficient, resulting in poor electroplating effect.

The drum rack 200 is arranged in the tank body 100, the inner frame 300 is arranged in the drum rack 200 and is used to place the workpiece to be plated, the reciprocating drive member 400 is installed on one side of the tank body 100, the reciprocating drive member 400 is used to drive the drum rack 200 and the inner frame 300 to swing back and forth, and the rotating member 500 is provided at the bottom of the inner frame 300, and the rotating member 500 is used to drive the inner frame 300 to rotate back and forth in the drum rack 200;

[0027] The cartridge holder 200 is vertically arranged in the center of the tank body 100;

[0028] In this embodiment, an appropriate amount of plating liquid is injected into the tank body 100, and then the workpiece is placed in the inner frame 300 and the inner frame 300 is installed in the drum frame 200. The reciprocating drive member 400 is started, and the reciprocating drive member 400 drives the drum frame 200 to swing back and forth in the tank body 100, and the inner frame 300 swings together in the drum frame 200. At the same time, the rotating member 500 located at the bottom of the tank body 100 causes the inner frame 300 to rotate back and forth when it swings.

[0029] In one embodiment, see Figure 1-Figure 3 The drum rack 200 is cage-shaped and includes an upper ring 210, a lower ring 220 and a plurality of first connecting rods 230. The upper ring 210 and the lower ring 220 are coaxially arranged. The top and bottom of the first connecting rod 230 are fixedly connected to the bottom of the upper ring 210 and the top of the lower ring 220 respectively. The plurality of first connecting rods 230 are evenly distributed between the upper ring 210 and the lower ring 220. The outer portion of the inner frame 300 is rotatably connected to the inner wall of the upper ring 210 and the inner wall of the lower ring 220.

[0030] The upper ring 210 is rotatably connected to the inner wall of the tank body 100 at a side away from the reciprocating drive member 400;

[0031] In this embodiment, the drum frame 200 is cage-shaped by providing an upper ring 210, a lower ring 220 and a first connecting rod 230, and one side of the upper ring 210 is connected to the reciprocating drive member 400. When the reciprocating drive member 400 is driven, the upper ring 210 rotates along the connection point corresponding to the reciprocating drive member 400 as the center of the circle, and drives the lower ring 220 to swing back and forth through the first connecting rod 230.

[0032] In one embodiment, see Figure 2 The inner frame 300 is cage-shaped and includes a top frame 310, a bottom frame 320 and a plurality of second connecting rods 330. The top frame 310 and the bottom frame 320 are coaxially arranged.

The outside of the top frame 310 is rotatably connected to the inner wall of the upper ring 210, the bottom frame 320 is rotatably connected to the inner wall of the lower ring 220, the rotating member 500 is rotatably connected to the bottom frame 320, and the plurality of second connecting rods 330 are fixedly connected to the same mounting frame 331.

[0033] In this embodiment, the inner frame 300 is cage-shaped by providing a top frame 310, a bottom frame 320 and a second connecting rod 330, and the inner frame 300 is rotatably provided in the drum frame 200. The top frame 310 is rotatably connected to the upper ring 210, and the bottom frame 320 is rotatably connected to the lower ring 220. When the upper ring 210 and the lower ring 220 swing, they can drive the top frame 310 and the bottom frame 320 to swing together.

[0034] In one embodiment, see Figure 1 - Figure 2 The reciprocating drive member 400 includes a bracket 410, a first rotating shaft 420, two first gears 430, a motor 440 and a half gear 450. The bracket 410 is fixedly connected to the top of one side of the trough body 100, the first rotating shaft 420 is rotatably connected to the bottom of the bracket 410, the two first gears 430 are respectively sleeved on both ends of the first rotating shaft 420, the motor 440 is installed below the two first gears 430, the half gear 450 is sleeved on the top of the output shaft of the motor 440, and the half gear 450 is respectively engaged with the two first gears 430. The end of the first rotating shaft 420 close to the trough body 100 passes through the trough body 100 and is fixedly connected to the side wall of the upper ring 210.

[0035] In this embodiment, the motor 440 is started, and the motor 440 drives the half gear 450 to rotate. The half gear 450 intermittently engages with the two first gears 430 on the first rotating shaft 420, so that the two first gears 430 rotate at different times and in different directions. The two first gears 430 can drive the upper ring 210 and other components to swing back and forth through the first rotating shaft 420.

[0036] In one embodiment, see Figure 1 - Figure 4 The self-rotating member 500 includes a second rotating shaft 510, a second gear 520, and a curved rack 530. The second rotating shaft 510 is rotatably connected to the bottom center of the lower ring 220. The top center of the second gear 520 is fixedly connected to the bottom end of the second rotating shaft 510. Both ends of the curved rack 530 are fixedly connected to the inner walls of both sides of the trough body 100, and the curved rack 530 is meshed with the second gear 520. The top of the second rotating shaft 510 is fixedly connected to a clamping rod 511. A clamping hole 321 is opened at the bottom of the base 320. The clamping rod 511 and the clamping hole 321 are both in a rice shape, and the clamping rod 511 is adapted to the clamping hole 321.

[0037] In this embodiment, the upper ring 210 and the lower ring 220 swing and drive the top frame 310 and the bottom frame 320 to swing together. At the same time, the 'M'-shaped clamping hole 321 on the bottom frame 320 is engaged with the 'M'-shaped clamping rod 511. At this time, the second gear 520 at the bottom of the lower ring 220 is engaged with the curved rack 530. The lower ring 220 swings, which causes the second gear 520 to mesh with the curved rack 530 and rotate. The rotation of the second gear 520 can rotate the second rotating shaft 510. The second rotating shaft 510 drives the bottom frame 310 and the top frame 320 to rotate through the clamping rod 511.

[0038] When the second gear 520 moves to one end side of the curved rack 530 and resets, the second gear 520 changes its rotation direction, thereby allowing the top frame 310 and the bottom frame 320 to complete reciprocating rotation.

[0039] In one embodiment, see Figure 2 , a handle 311 is provided on the top of the top frame 310;

[0040] In this embodiment, the handle 311 can be used to pull the top frame 310 and the bottom frame 320 .

[0041] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the present invention is described in detail: an appropriate amount of electroplating liquid is injected into the tank body 100, and then the workpiece is placed on the mounting bracket 331 of the inner frame 300. The drum frame 200 is cage-shaped by setting the upper ring 210, the lower ring 220 and the first connecting rod 230. The inner frame 300 is cage-shaped by setting the top frame 310, the bottom frame 320 and the second connecting rod 330, and the inner frame 300 is rotated and arranged in the drum frame 200. The motor 440 is started, and the motor 440 drives the half gear 450 to rotate. The half gear 450 intermittently engages with the two first gears 430 on the first rotating shaft 420, so that the two first gears 430 rotate at different times and in different directions. The two first gears 430 can thereby drive the upper ring 210 and the lower ring 210 through the first rotating shaft 420. 220 swings and drives the top frame 310 and the bottom frame 320 to swing together. At the same time, the M-shaped clamping hole 321 on the bottom frame 320 is engaged with the M-shaped clamping rod 511. At this time, the second gear 520 at the bottom of the lower ring 220 is engaged with the curved rack 530. The lower ring 220 swings, which can make the second gear 520 mesh with the curved rack 530 and rotate. The rotation of the second gear 520 can rotate through the second rotating shaft 510, and the second rotating shaft 510 drives the bottom frame 310 and the top frame 320 to rotate through the clamping rod 511. This device improves the stirring degree of the plating solution by the large-scale reciprocating swing of the drum frame 200 and the inner frame 300, and then improves the reaction efficiency of the plating solution and the workpiece by making the workpiece rotate with the inner frame 300, thereby ensuring the overall stirring effect.
