Description

Technical Field

[0001] The present invention relates to the technical field of electroplating, and more particularly to a batch movable electroplating treatment device for automobile interior plastic parts. Background Art

[0002] The texture of automobile interior plastic parts is originally quite ordinary. By electroplating the plastic parts with electroplating equipment, a metal coating can be formed on their surface, giving the plastic parts a metal-like luster and texture, making the interior look more high-quality, and improving the quality and visual appeal of the entire vehicle. After electroplating, the interior decorative strips of some high-end models will reflect a bright luster under the exposure to light, which matches with other materials in the car.

[0003] Patent publication number CN221971720U discloses a batch electroplating device for metal parts. This technology utilizes two first and two second conveyor wheels, each housing a conveyor belt. A drive mechanism is mounted on a horizontal plate to rotate the first conveyor wheel on the right side. Multiple, evenly distributed spring clips are fixed to the outer surface of the conveyor belt. This device facilitates batch electroplating of metal parts and automatically unloads the plated parts, improving electroplating efficiency and making them easier to use. However, this technology still suffers from the following drawbacks.

[0004] When electroplating automotive interior plastic parts in batches, multiple plastic parts must first be positioned and placed on a hanger, and then moved as a whole to the electroplating tank for immersion electroplating. However, the plastic parts and the hanger are in contact at fixed points, which will cause the contact areas to be blocked during electroplating. Since it is difficult to move and displace these contact blocking points during the electroplating process, these areas are difficult to fully contact and plate, and it is difficult for the electroplating to fully cover them. Therefore, the overall electroplating quality of batch automotive interior plastic parts will be greatly reduced, affecting the product quality of automotive interior plastic parts. Summary of the Invention

Each set of curved spring clips consists of two, with adjacent curved spring clips symmetrically positioned about the center of the interior plastic component. The vertical cross-section of each curved spring clip is circular. The linkage ring is slidably connected to the outer wall of the guide column. The top of the top scraping bar is chamfered.

[0007] When this technology is in use, the pressure strip squeezes multiple groups of arc-shaped spring pieces downward, and the pressure strip squeezes two adjacent arc-shaped spring pieces downward, and the bottom ends of the two arc-shaped spring pieces are close to each other, and the linkage ring drives the protrusion to move, and the two linkage rings move close to each other along the outer wall of the groove column, and the hanging strip drives the top scraper to move, and the two adjacent top scrapers move close to each other along the top inner groove of the interior plastic part, so that the part that the top scraper strip and the interior plastic part initially contact and block is fully exposed to the electroplating solution.

[0008] Preferably, a linkage block is fixedly connected to the bottom end of the outer wall of the linkage ring; one end of the linkage block is fixedly connected to a connecting strip, a bottom strip is fixedly connected to one side of the connecting strip near its bottom end, and a hanging bottom buckle is fixedly installed at one end of the bottom strip, and the hanging bottom buckle is slidably connected to the interior plastic part.

[0009] When this technology is in use, when the two linkage rings move closer to each other, the linkage ring will drive the linkage block to move closer to the other linkage ring, the connecting strip will drive the bottom strip to move to the left, and the contact part between the bottom strip and the inner groove at the bottom of the interior plastic part will begin to move and displace, and the part that was initially blocked by the suspension bottom buckle and the interior plastic part will be fully exposed to the electroplating solution.

[0010] Preferably, a sliding bar is fixedly connected to the outer wall of the connecting bar near its middle position; a diagonal hanging bar is slidably connected to one side of the sliding bar, the diagonal hanging bar is slidably connected to the interior plastic part, and one end of the diagonal hanging bar is fixedly connected to an oblique sleeve, the inner wall of the oblique sleeve is slidably connected to an oblique column, the two ends of the oblique column are fixedly connected to the same oblique frame, the oblique sleeve is slidably connected to the oblique frame, a gap is provided between the connecting bar and the oblique frame, and the oblique frame is fixedly connected to the electroplating hanging frame.

A vertical bar is slidably connected to one side of each electroplating hanging frame, and the vertical bar is fixedly connected to the pressure bar; a horizontal bar is provided at the top of the vertical bar, and multiple vertical bars are fixedly connected to the horizontal bar.

[0011] A micro-electric cylinder is mounted on the top surface of the horizontal bar. The outer wall of the micro-electric cylinder is fixedly connected to the electroplating hanger, and the output end of the micro-electric cylinder is used to drive the horizontal bar. The micro-electric cylinder is electrically connected to the controller. The outer wall of the electroplating hanger is slidably connected to a cathode plug-in terminal near both ends.

[0012] When this technology is in use, when the connecting bar moves to the left, it will also drive the sliding bar to move to the left, and the oblique hanging bar will slide along the outer wall of the sliding bar at the same time, and the oblique sleeve will move obliquely left and upward along the outer wall of the oblique column. In this way, the oblique hanging bar will be tilted and moved to the left and upward in the middle inner groove of the interior plastic part, and the contact part between the oblique hanging bar and the middle inner groove of the interior plastic part will begin to move and displace, so that the part that was initially blocked by the oblique hanging bar and the interior plastic part is fully exposed to the electroplating solution.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The present invention adopts a multi-point synchronous position-changing electroplating component, which has significant advantages in multi-point synchronous position-changing electroplating in the top inner groove. The micro-electric cylinder is supported by the electroplating suspension frame to push the horizontal bar to move the vertical bar downward, and multiple pressure strips move downward synchronously. The pressure strips slide along the slide groove to squeeze multiple groups of symmetrical arc-shaped spring pieces, and then the bottom of the arc-shaped spring piece drives the linkage ring to move along the outer wall of the groove column, and the protrusion moves along the guide groove. The two top scrapers can move close to each other along the top inner groove of the interior plastic part, fully exposing the parts that are initially blocked by the top scraper bar and the interior plastic part, realizing full contact electroplating with the electroplating liquid, greatly improving the comprehensiveness and uniformity of electroplating, and ensuring the electroplating quality of batch interior plastic parts.

[0015] 2. The present invention is ingenious in its design of synchronous displacement of the bottom inner groove. When the two linkage rings move toward each other, the linkage ring drives the linkage block toward the other linkage ring, and at the same time drives the connecting bar to move to the left, thereby causing the bottom bar to slide along the bottom inner groove of the interior plastic part. This design cleverly allows the contact area between the bottom bar and the bottom inner groove of the interior plastic part to move and displace, so that the part of the interior plastic part originally blocked by the hanging bottom buckle is fully exposed to the electroplating solution. This innovative mechanism ensures full contact between the electroplating solution and the bottom inner groove of the plastic part, effectively improving the integrity and uniformity of the electroplating, significantly enhancing the electroplating effect, and ensuring product quality.

[0016] 3. The present invention exhibits an excellent design in the synchronous displacement electroplating of the middle inner groove. When the connecting bar moves to the left, it drives the sliding bar to move left synchronously, and then causes the inclined hanging bar to move obliquely to the left and upward. The inclined hanging bar then drives the inclined sleeve to move obliquely to the left and upward along the outer wall of the inclined column and the inner wall of the inclined frame. This design cleverly allows the inclined hanging bar to displace and move in the middle inner groove of the interior plastic part, fully exposing the part that was originally blocked by the inclined hanging bar from contacting the interior plastic part, realizing full contact between the electroplating solution and the middle inner groove of the plastic part, greatly improving the uniformity and integrity of the electroplating, and ensuring the quality of the electroplating.

[0017] In summary, firstly, the two top scraping strips can be displaced and moved closer to each other along the top inner groove of the interior plastic part, cleverly exposing the originally contact and obstructed parts; secondly, the bottom strip is moved and displaced according to the contact part of the bottom inner groove of the interior plastic part, so that the parts obstructed by the hanging bottom buckle are fully exposed to the electroplating liquid; at the same time, the oblique hanging strip is flexibly displaced and moved in the middle inner groove of the interior plastic part, so that the originally contact and obstructed parts are fully exposed. This design ensures that all obstructed parts are fully exposed to the electroplating liquid through the coordinated displacement of multiple parts, so that the electroplating liquid and the interior plastic parts are fully in contact with each other for electroplating, which greatly improves the comprehensiveness and uniformity of the electroplating and effectively guarantees the quality of the electroplating.

[0033] In this embodiment, if Figure 5 - Figure 7 As shown, a slide bar 16 is fixedly connected to the outer wall of the connecting bar 13 near its center. A diagonal hanging bar 17 is slidably connected to one side of the slide bar 16. The diagonal hanging bar 17 is slidably connected to the interior plastic part 11.

The vertical cross-section of the slide bar 16 is L-shaped, and the outer walls of the slide bar 16 and the diagonal hanging bar 17 are both smooth.

[0034] In this embodiment, if Figure 3 As shown, a sliding groove 21 is opened on the outer wall of the pressure strip 22, and the pressure strip 22 is slidably connected to the sliding groove 21, so that the pressure strip 22 can slide downward along the inner wall of the sliding groove 21, thereby stably guiding the pressure strip 22 to achieve a sliding operation.

[0035] In this embodiment, if Figure 8 - Figure 9As shown, one side of each electroplating hanging frame 3 is slidably connected with a vertical bar 23, and the vertical bar 23 is fixedly connected to the pressure bar 22; a horizontal bar 24 is provided at the top of the vertical bar 23, and multiple vertical bars 23 are fixedly connected to the horizontal bar 24, and a micro-electric cylinder 25 is installed on the upper surface of the horizontal bar 24. The outer wall of the micro-electric cylinder 25 is fixedly connected to the electroplating suspension frame 2, and the output end of the micro-electric cylinder 25 is used to push the horizontal bar 24 to move.

[0036] In this embodiment, if Figure 2 As shown, the outer wall of the electroplating hanger 2 and near its two end positions are slidably connected with a cathode plug-in terminal 27, the cathode plug-in terminal 27 is fixedly connected to the electroplating tank 1, and the bottom end of the inner wall of the electroplating tank 1 is fixedly installed with an anode terminal 28, and the anode terminal 28 and the cathode plug-in terminal 27 are both electrically connected to the controller 30, so that after installation, the lifting hanger 26 is lifted into the electroplating tank 1 by the lifting crane, and the lifting hanger 26 drives the electroplating hanger 2 to move downward, and the electroplating hanger 2 is plugged into the inner wall of the cathode plug-in terminal 27. The controller 30 starts the cathode plug-in terminal 27, and at the same time, the controller 30 opens the anode terminal 28, so that the electroplating liquid inside the electroplating tank 1 can electroplate the interior plastic parts 11. One side of the outer wall of the electroplating hanging frame 3 is connected with multiple delivery pipes 29, and the controller 30 is fixed on the outer wall of the electroplating tank 1 and below the top of the delivery pipe 29, so as to facilitate the electroplating liquid to be poured into the electroplating tank 1 through the delivery pipe 29. At the same time, the controller 30 can start the micro electric cylinder 25 to realize the driving operation.

[0037] The working principle of the batch mobile electroplating treatment device for automobile interior plastic parts of the present invention is as follows:

[0038] First, when performing batch electroplating, the electroplating solution is first poured into the electroplating tank 1 through the delivery pipe 29. Simultaneously, the top inner groove of the interior plastic part 11 is slidably inserted into the outer wall of the top scraper bar 10, and the middle inner groove of the interior plastic part 11 is slidably inserted into the inclined surface of the inclined hanging bar 17. Simultaneously, the bottom inner groove of the interior plastic part 11 is inserted into the outer wall of the suspension bottom buckle 15. In this way, all batches of interior plastic parts 11 are installed. After installation, the lifting hanger 26 is lifted into the electroplating tank 1 using a lifting crane. The lifting hanger 26 drives the electroplating hanger 2 downward, and the electroplating hanger 2 is inserted into the inner wall of the cathode plug-in terminal 27.

[0039] At the same time, the electroplating hanger 2 immerses multiple electroplating hanger frames 3 in the electroplating tank 1, and multiple electroplating hanger frames 3 drive the tank column 6 to move the linkage ring 5 downward, and the linkage ring 5 drives the hanging bar 9 to move the top scraper 10 downward, and the top scraper 10 drives the interior plastic parts 11 into the electroplating solution inside the electroplating tank 1, so that the controller 30 starts the cathode plug-in terminal 27, and at the same time the controller 30 opens the anode terminal 28, so that the cathode plug-in terminal 27 conducts electricity to the electroplating hanger 2, and the electroplating hanger 2 conducts electricity to the multiple electroplating hanger frames 3, and the electricity The plated hanging frame 3 is conductive to the slot column 6, the slot column 6 is conductive to the linkage ring 5, the linkage ring 5 is conductive to the hanging bar 9, the hanging bar 9 is conductive to the top scraper bar 10, and the top scraper bar 10 realizes electroplating treatment on the interior plastic part 11, wherein the hanging bar 9, the linkage ring 5 and the protrusion 8 are integrated into a molding operation, and at the same time, the contact part between the top scraper bar 10 and the interior plastic part 11, the contact part between the oblique hanging bar 17 and the interior plastic part 11, and the contact part between the suspension bottom buckle 15 and the interior plastic part 11 are all blocked and not exposed for electroplating treatment.

[0040] Secondly, when the present invention performs multi-point synchronous displacement electroplating in the top inner groove, the micro-electric cylinder 25 is supported by the electroplating suspension frame 2, and the controller 30 starts the micro-electric cylinder 25. The micro-electric cylinder 25 pushes the horizontal bar 24 to move downward, and the horizontal bar 24 drives multiple vertical bars 23 to move downward synchronously. The vertical bar 23 drives multiple pressure bars 22 to move downward synchronously, and the pressure bar 22 slides downward along the inner wall of the slide groove 21. The pressure bar 22 squeezes multiple groups of arc-shaped spring pieces 4 downward. The number of each group of arc-shaped spring pieces 4 is two and symmetrically arranged, so that the pressure bar 22 squeezes the two adjacent arc-shaped spring pieces 4 downward, and the top ends of the two arc-shaped spring pieces 4 are squeezed downward by force, and the bottom ends of the two arc-shaped spring pieces 4 are close to each other. The arc-shaped spring piece 4 drives the linkage ring 5 to move, and the linkage ring 5 drives the protrusion 8 to move, and the protrusion 8 is guided and moved along the inside of the guide groove 7. At the same time, the two linkage rings 5 ​​move closer to each other along the outer wall of the groove column 6, the linkage ring 5 drives the hanging bar 9 to move, and the hanging bar 9 drives the top scraper bar 10 to move. The two adjacent top scrapers 10 move closer to each other along the top inner groove of the interior plastic part 11, so that the parts that are initially blocked by the top scraper bar 10 are fully exposed to the electroplating solution, achieving full contact with the electroplating solution for electroplating operation.

[0041] At the same time, when the present invention performs synchronous displacement of the bottom inner groove, when the two linkage rings 5 ​​move closer to each other, the linkage ring 5 will drive the linkage block 12 to move closer to the other linkage ring 5, and the linkage ring 5 will drive the connecting bar 13 to move left, and the connecting bar 13 will drive the bottom bar 14 to move left, and the bottom bar 14 will displace and slide along the bottom inner groove of the interior plastic part 11, and the contact part between the bottom bar 14 and the bottom inner groove of the interior plastic part 11 begins to move and displace, so that the part that was initially blocked by the hanging bottom buckle 15 and the interior plastic part 11 is fully exposed to the electroplating solution, so that full contact with the electroplating solution is achieved for electroplating operation.

[0042] At the same time, during the synchronous displacement electroplating of the central inner groove of the present invention, when the connecting bar 13 moves leftward, it simultaneously drives the slide bar 16 leftward. The slide bar 16 drives the inclined hanging bar 17 to move obliquely leftward and upward. The inclined hanging bar 17 simultaneously slides along the outer wall of the slide bar 16. The inclined hanging bar 17 drives the inclined sleeve 18 to move obliquely leftward and upward. The inclined sleeve 18 moves obliquely leftward and upward along the outer wall of the inclined column 19. The inclined sleeve 18 moves obliquely leftward and upward along the inner wall of the inclined frame 20. At the same time, the electroplating hanging frame 3 supports the inclined frame 20, increasing its stability. The inclined frame 20 supports the inclined column 19, increasing its stability. In this way, the inclined hanging bar 17 is displaced obliquely leftward and upward within the central inner groove of the interior plastic part 11. The contact area between the inclined hanging bar 17 and the interior plastic part 11 begins to move and displace, so that the area initially blocked by the contact area between the inclined hanging bar 17 and the interior plastic part 11 is fully exposed to the electroplating solution, achieving full contact with the electroplating solution for the electroplating operation.
