Description

Technical Field

[0001] This utility model relates to the field of optimization devices, and more specifically, to a current density optimization device for gold electroplating. Background Technology

[0002] In electrolytic processes such as electroplating and anodizing, the current density passing through the parts is a crucial process parameter. It directly affects whether the parts will suffer from insufficient film thickness or no coating / oxide film formation due to insufficient current density, or serious quality problems such as ablation due to excessive current density.

[0003] A search revealed that Chinese patent CN219059193U discloses "a device for controlling electrolytic current density." This device controls the electrolytic current density by analogy between a test plate and the workpiece, utilizing industrial computers or microcontrollers and other control system hardware and software to automatically collect and record process parameters such as current, voltage, temperature, and time during the electrolytic processing. The control system then calculates the current density during the anodizing process in real time according to an established mathematical model formula, achieving automatic control. However, this method still has the following drawbacks:

[0004] (1) Existing current density devices adjust current density through a control system based on a mathematical model. The mathematical model needs to be built, which requires a lot of cost, increasing the cost of using the optimization device.

[0005] (2) Existing current density optimization devices require a lot of time to perform separate calculations before use, which affects the efficiency of optimization.

[0006] Therefore, we have made improvements to this and proposed a current density optimization device for gold electroplating. Utility Model Content

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a current density optimization device for gold electroplating, including a frame plate 1, a plug-in assembly between the frame plates 1, and a replacement assembly between the rear sides of the frame plates 1.

[0036] The plug-in assembly includes an inner groove 201 opened inside the upper end of the frame plate 1, a first bevel gear 202 is provided on the inner wall of the front end of the inner groove 201, and a first motor 203 is connected to the front end of the first bevel gear 202.

[0037] The replacement component includes a rotating rod 301 located between the rear sides of the frame plate 1. A collar 302 is fitted onto the outer wall of the rotating rod 301. Graphite electrode heads 303 are provided on both the front and rear outer walls of the collar 302.

[0038] like Figure 3As shown, the inner wall of the inner groove 201 is provided with a second bevel gear 204 that cooperates with the first bevel gear 202. The first motor 203 is controlled to run and drive the first bevel gear 202 connected to it to rotate. The meshing drives the second bevel gear 204 to rotate, which in turn drives the screw 206 connected to it to rotate.

[0039] like Figure 3 As shown, a sliding groove 205 is provided on the outer side of the inner groove 201 near the second bevel gear 204. A screw 206 is provided inside the sliding groove 205. A sliding plate 207 is fitted on the outer wall of the screw 206. When the screw 206 rotates, the sliding plate 207 is driven to slide in the sliding groove 205 through the thread engagement provided on the outer wall. The connecting plate 208 installed drives the lower end connector 209 to slide towards the frame plate 1, so that the connector 209 can disengage from both sides of the graphite electrode head 303.

[0040] like Figure 3 As shown, a sliding plate 207 is provided on the lower surface of the side of the sliding plate 207 away from the inner groove 201. A connecting plate 208 is installed at the lower end of the sliding plate 207, and the connecting plate 208 is movably set inside the center of the frame plate 1. The sliding plate 207 slides in the sliding groove 205. The connecting plate 208 drives the connector 209 at the lower end to slide towards the frame plate 1, so that the connector 209 can disengage from both sides of the graphite electrode head 303 to facilitate the replacement of the graphite electrode head 303. After replacement, the first motor 203 is controlled to reverse, driving the screw 206 to reverse and engage, driving the connector 209 to move towards both sides of the graphite electrode head 303 to achieve efficient insertion.

[0041] like Figure 2 As shown, the right end of the rotating rod 301 is connected to an electric roller 304. The outer wall of the frame plate 1 at the front of the electric roller 304 is fitted with an outer plate 305, which is locked to the surface of the electric roller 304 by the snap-fit ​​pattern on the surface, so that the selection and adjustment of the graphite electrode head 303 is more stable.

[0042] like Figure 4 As shown, the outer plate 305 has a telescopic groove 306 inside, and a locking plate 307 is movably installed inside the telescopic groove 306. Limiting grooves 308 are provided on both sides of the telescopic groove 306. Limiting plates 309 that cooperate with the limiting grooves 308 are provided on both sides of the locking plate 307. The limiting plates 309 are embedded under the limiting grooves 308, so that the locking plate 307 can slide stably towards the electric roller 304 in the telescopic groove 306 and be locked on the surface of the electric roller 304 by the snap patterns provided on the surface.

[0043] like Figure 4As shown, a toothed roller 310 is provided on the lower surface of the locking plate 307. A second motor 311 is connected to the side wall of the toothed roller 310. A bottom groove 312 is provided on the lower inner wall of the telescopic groove 306. A toothed plate 313 that cooperates with the toothed roller 310 is provided inside the bottom groove 312. When the graphite electrode head 303 needs to be replaced, the electric roller 304 is controlled to rotate, which drives the rotating rod 301 connected to it to rotate, which drives the collar 302 to rotate. The graphite electrode head 303 with different graphite densities is adjusted and aligned with the two connectors 209. After alignment, the second motor 311 is controlled to run, which drives the toothed roller 310 connected to it to rotate, so that they mesh with each other on the surface of the toothed plate 313.

[0044] Specifically, in use, when the graphite electrode head 303 needs to be replaced, the first motor 203 is controlled to rotate, driving the first bevel gear 202 connected to it to rotate. This meshes with the second bevel gear 204, which in turn rotates the screw 206 connected to it. Through the threaded engagement on the outer wall, the slide plate 207 slides within the slide groove 205. The connecting plate 208 then drives the lower connector 209 to slide towards the support plate 1, allowing the connector 209 to disengage from both sides of the graphite electrode head 303 for easy replacement. After replacement, the first motor 203 is controlled to reverse, causing the screw 206 to reverse and engage, moving the connector 209 towards both sides of the graphite electrode head 303. Efficient insertion allows for quick docking after replacement. When the graphite electrode head 303 needs to be replaced, the electric roller 304 is rotated to drive the connected rotating rod 301 to rotate, which in turn drives the collar 302 to rotate. The graphite electrode head 303 with different graphite densities is adjusted and aligned with the connectors 209 on both sides. After alignment, the second motor 311 is controlled to rotate the connected toothed roller 310, so that they mesh relative to each other on the surface of the toothed plate 313. Under the limitation of the limiting plate 309 embedded in the limiting groove 308, the locking plate 307 slides stably towards the electric roller 304 in the telescopic groove 306. It is locked by the snap-fit ​​pattern on the surface of the electric roller 304, making the selection and adjustment of the graphite electrode head 303 more stable.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
