Description

Technical Field

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

[0002] The original texture of automotive interior plastic parts is relatively ordinary. By electroplating the plastic parts with an electroplating treatment device, a metal coating can be formed on their surfaces, endowing the plastic parts with a metallic luster and texture, making the interior look more quality, enhancing the quality sense and visual attraction of the whole vehicle. After electroplating treatment, the interior decorative strips of some high-end models will reflect a bright luster under the illumination of light, matching with other materials in the vehicle.

[0003] In the existing published literature, the patent with the patent announcement number CN221971720U discloses a batch electroplating treatment device for metal parts. This technology has two first conveyor wheels and two second conveyor wheels jointly sleeved with a conveyor belt. A driving mechanism for driving the right first conveyor wheel to rotate is arranged on the cross plate, and a plurality of uniformly distributed spring clips are fixedly arranged on the outer surface of the conveyor belt. The utility model is convenient for batch electroplating treatment of metal parts, and can automatically unload the electroplated metal parts, which is convenient for improving the electroplating efficiency of metal parts and is convenient for people to use. However, this technology still has the following defects.

[0004] When batch electroplating automotive interior plastic parts, multiple plastic parts need to be positioned and placed on a suspension rack first, and then the whole is moved to an electroplating tank for immersion electroplating. However, the plastic parts and the suspension rack are in fixed-point contact, which will cause the contact parts to be blocked during electroplating. Since it is difficult to move and displace these contact and blocking points during the electroplating process, it is difficult for these parts to fully contact electroplating, and electroplating cannot fully cover, so 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

[0005] In order to overcome the above defects of the prior art, the present invention provides the following technical solutions: A batch mobile electroplating treatment device for automotive interior plastic parts, including an electroplating tank and a controller. An electroplating suspension rack is slidably connected to the inner wall of the electroplating tank. A plurality of electroplating hanging frames are fixedly connected to one side of the outer wall of the electroplating suspension rack. A multi-point synchronous displacement electroplating assembly is arranged inside the electroplating hanging frame; the multi-point synchronous displacement electroplating assembly includes a plurality of pressing strips slidably arranged inside the electroplating hanging frame. A plurality of groups of arc-shaped elastic pieces are fixedly connected to the lower surface of the pressing strip. The bottom end of each arc-shaped elastic piece is fixedly connected with a linkage ring. A groove column is connected inside the linkage ring. The groove column is fixedly connected with the electroplating hanging frame. A guiding groove is opened on the inner wall of the groove column. A convex block is fixedly connected to the top end of the inner wall of the linkage ring.

[0006] The bump is slidably connected to the groove column to which the guiding groove belongs. One side of the outer wall of each linkage ring is fixedly connected with a hanging strip, and the upper surface of the hanging strip is fixedly connected with a top scraping strip. An interior plastic part is slidably connected above the top scraping strip. The number of each group of arc-shaped elastic pieces is set to two, and two adjacent arc-shaped elastic pieces are symmetrically arranged about the middle of the interior plastic part. The vertical cross-sectional shape of the arc-shaped elastic piece is arc-shaped. The linkage ring is slidably connected to the outer wall of the groove column, and the top of the top scraping strip is processed with a rounded corner.

[0007] When the present technology is in use, the pressing strip presses down on multiple groups of arc-shaped elastic pieces. The pressing strip presses down on two adjacent arc-shaped elastic pieces, and the bottom ends of the two arc-shaped elastic pieces approach each other. The linkage ring drives the bump to move, and the two linkage rings move closer to each other along the outer wall of the groove column. The hanging strip drives the top scraping strip to move, and two adjacent top scraping strips move closer to each other along the inner groove at the top of the interior plastic part, so that the parts initially covered by the contact between the top scraping strip and the interior plastic part are fully exposed in 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 with a connecting strip, a bottom strip is fixedly connected to one side of the connecting strip and near its bottom end position, and a hanging bottom buckle is fixedly installed at one end of the bottom strip. The hanging bottom buckle is slidably connected to the interior plastic part.

[0009] When the present 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 drives the bottom strip to move leftward, and the contact part between the bottom strip and the inner groove at the bottom of the interior plastic part starts to move and displace, so that the parts initially covered by the contact between the hanging bottom buckle and the interior plastic part are fully exposed in the electroplating solution.

[0010] Preferably, a sliding strip is fixedly connected to the outer wall of the connecting strip and near its middle position; an inclined hanging strip is slidably connected to one side of the sliding strip. The inclined hanging strip is slidably connected to the interior plastic part, and one end of the inclined hanging strip is fixedly connected with an inclined sleeve. An inclined column is slidably connected to the inner wall of the inclined sleeve. The same inclined frame is fixedly connected to the two ends of the inclined column. The inclined sleeve is slidably connected to the inclined frame. There is a gap between the connecting strip and the inclined frame, and the inclined frame is fixedly connected to the electroplating hanging frame. The vertical cross-sectional shape of the sliding strip is L-shaped, and the outer walls of the sliding strip and the inclined hanging strip are both smooth surfaces. A sliding groove is formed in the outer wall of the pressing strip, and the pressing strip is slidably connected to the sliding groove. A vertical strip is slidably connected to one side of each electroplating hanging frame, and the vertical strip is fixedly connected to the pressing strip; a horizontal strip is provided at the top of the vertical strip, and multiple vertical strips are fixedly connected to the horizontal strip.

[0011] A micro electric cylinder is installed on the upper surface of the horizontal bar. The outer wall of the micro electric cylinder is fixedly connected to the electroplating suspension hanger, and the output end of the micro electric cylinder is used to push the horizontal bar to move. The micro electric cylinder is electrically connected to the controller. Cathode plug-in terminals are slidably connected to the outer wall of the electroplating suspension hanger near both ends thereof. The cathode plug-in terminals are fixedly connected to the electroplating tank. An anode end is fixedly installed at the bottom end of the inner wall of the electroplating tank. Both the anode end and the cathode plug-in terminals are electrically connected to the controller. A plurality of delivery pipes are plugged and communicated with one side of the outer wall of the electroplating hanging frame. The controller is fixedly located on the outer wall of the electroplating tank and below the top of the delivery pipes.

[0012] When in use, when the connecting bar moves leftward, it will drive the sliding bar to move leftward at the same time. The inclined hanging bar slides along the outer wall of the sliding bar at the same time, and the inclined sleeve tilts and moves upward to the left along the outer wall of the inclined column. In this way, the inclined hanging bar tilts and moves upward to the left in the middle inner groove of the interior plastic part, and the contact part between the inclined hanging bar and the middle inner groove of the interior plastic part starts to move and displace, so that the part initially contacted and blocked by the inclined hanging bar and the interior plastic part is fully exposed in the electroplating solution.

[0013] The technical effects and advantages of the present invention: 1. The present invention adopts a multi-point synchronous displacement electroplating component, which has significant advantages in multi-point synchronous displacement electroplating in the top inner groove. The electroplating suspension hanger supports the micro electric cylinder, which pushes the horizontal bar to make the vertical bar move downward, and multiple pressing bars move downward synchronously. The pressing bars slide along the sliding grooves to squeeze a plurality of groups of symmetric arc-shaped elastic pieces. Then, the bottom of the arc-shaped elastic pieces drives the linkage ring to move along the outer wall of the groove column, and the convex block moves along the guide groove. The two top scraping bars can move closer and displace each other along the top inner groove of the interior plastic part, fully exposing the part initially contacted and blocked by the top scraping bars and the interior plastic part, realizing full contact between the electroplating solution and the electroplating, greatly improving the comprehensiveness and uniformity of electroplating, and ensuring the electroplating quality of batch interior plastic parts.

[0014] 2. The present invention is ingenious in the synchronous displacement design of the bottom inner groove. When the two linkage rings move closer to each other, the linkage rings drive the linkage blocks to approach another linkage ring, and at the same time drive the connecting bar to move leftward, so as to make the bottom bar displace and slide along the bottom inner groove of the interior plastic part. This design ingeniously makes the contact part between the bottom bar and the bottom inner groove of the interior plastic part move and displace, so that the part of the interior plastic part originally blocked by the hanging bottom buckle is fully exposed in the electroplating solution. This innovative mechanism ensures full contact between the electroplating solution and the bottom inner groove of the plastic part, effectively improves the integrity and uniformity of electroplating, significantly enhances the electroplating effect, and ensures the product quality.

[0015] 3. The present invention demonstrates excellent design in the synchronous displacement electroplating of the middle inner groove. When the connecting bar moves leftward, it drives the sliding bar to move leftward synchronously, thereby causing the inclined hanging bar to tilt and move upward to the left. The inclined hanging bar then drives the inclined sleeve to tilt and move upward to the left along the outer wall of the inclined column and the inner wall of the inclined frame. This design ingeniously enables the inclined hanging bar to displace and move in the middle inner groove of the interior plastic part, fully exposing the parts that were originally blocked by the inclined hanging bar from contacting the interior plastic part, achieving full contact between the electroplating solution and the middle inner groove of the plastic part, greatly improving the uniformity and integrity of electroplating, and ensuring the electroplating quality.

[0016] In summary, first, the two top scraping bars can move closer to each other and displace in the top inner groove of the interior plastic part, ingeniously exposing the originally blocked contact parts. Second, the bottom bar moves and displaces at the contact part of the bottom inner groove of the interior plastic part, allowing the parts blocked by the suspended bottom buckle to be fully exposed to the electroplating solution. At the same time, the inclined hanging bar flexibly displaces and moves in the middle inner groove of the interior plastic part, enabling the originally blocked contact parts to be fully exposed. This design ensures that all blocked parts are fully exposed to the electroplating solution through the coordinated displacement of multiple parts, allowing the electroplating solution to fully contact and electroplate the interior plastic part, greatly improving the comprehensiveness and uniformity of electroplating, and effectively ensuring the electroplating quality.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1 - Figure 9 Shown is a batch mobile electroplating treatment device for automotive interior plastic parts. A multi-point synchronous displacement electroplating assembly is provided on the batch mobile electroplating treatment device for automotive interior plastic parts. The setting of the multi-point synchronous displacement electroplating assembly can fully expose the parts initially blocked by the contact between the top scraping strip 10 and the interior plastic part 11, enabling the electroplating solution to fully contact the electroplating, greatly improving the comprehensiveness and uniformity of electroplating, and ensuring the electroplating quality of the batch of interior plastic parts 11. The specific structural settings of the multi-point synchronous displacement electroplating assembly are as follows.

[0029] In this embodiment, as Figure 1 - Figure 5 Shown, on one side of the outer wall of the electroplating suspension hanger 2, a plurality of electroplating hanging frames 3 are fixedly connected. The inner wall of the electroplating hanging frame 3 is provided with a multi-point synchronous displacement electroplating assembly; the multi-point synchronous displacement electroplating assembly includes a plurality of pressing strips 22 slidably arranged on the inner wall of the electroplating hanging frame 3. The lower surface of the pressing strip 22 is fixedly connected with multiple groups of arc-shaped elastic pieces 4. The bottom end of each arc-shaped elastic piece 4 is fixedly connected with a linkage ring 5. A groove column 6 is connected inside the linkage ring 5. The groove column 6 is fixedly connected with the electroplating hanging frame 3, and a guiding groove 7 is opened on the inner wall of the groove column 6.

[0030] The top end of the inner wall of the linkage ring 5 is fixedly connected with a convex block 8, and the convex block 8 is slidably connected with the groove column 6 to which the guide groove 7 belongs. One side of the outer wall of each linkage ring 5 is fixedly connected with a hanging strip 9, the upper surface of the hanging strip 9 is fixedly connected with a top scraping strip 10, and an interior plastic part 11 is slidably connected above the top scraping strip 10. The number of each group of arc-shaped elastic pieces 4 is set to two, and two adjacent arc-shaped elastic pieces 4 are symmetrically arranged about the middle of the interior plastic part 11. The vertical cross-sectional shape of the arc-shaped elastic piece 4 is arc-shaped. The linkage ring 5 is slidably connected with the outer wall of the groove column 6, and the top end of the top scraping strip 10 is processed with a rounded corner.

[0031] In this embodiment, as Figure 5 - Figure 6 shown, the bottom end of the outer wall of the linkage ring 5 is fixedly connected with a linkage block 12; one end of the linkage block 12 is fixedly connected with a connecting strip 13, one side of the connecting strip 13 and near its bottom end position is fixedly connected with a bottom strip 14, and one end of the bottom strip 14 is fixedly installed with a hanging bottom buckle 15, and the hanging bottom buckle 15 is slidably connected with the interior plastic part 11.

[0032] In this embodiment, as Figure 5 - Figure 7 shown, a sliding strip 16 is fixedly connected to the outer wall of the connecting strip 13 and near its middle position; a slanting hanging strip 17 is slidably connected to one side of the sliding strip 16, the slanting hanging strip 17 is slidably connected with the interior plastic part 11, and one end of the slanting hanging strip 17 is fixedly connected with a slanting sleeve 18. An inclined column 19 is slidably connected to the inner wall of the slanting sleeve 18. The same slanting frame 20 is fixedly connected to both ends of the inclined column 19. The slanting sleeve 18 is slidably connected with the slanting frame 20. There is a gap between the connecting strip 13 and the slanting frame 20, and the slanting frame 20 is fixedly connected with the electroplating hanging frame 3. The vertical cross-sectional shape of the sliding strip 16 is L-shaped, and the outer walls of the sliding strip 16 and the slanting hanging strip 17 are both smooth surfaces.

[0033] In this embodiment, as Figure 3 shown, a chute 21 is opened on the outer wall of the pressing strip 22, and the pressing strip 22 is slidably connected with the chute 21, so that the pressing strip 22 can slide down along the inner wall of the chute 21 to stably realize the guiding sliding operation of the pressing strip 22.

[0034] In this embodiment, as Figure 8 - Figure 9As shown in the figure, a vertical bar 23 is slidably connected to one side of each electroplating hanging frame 3, and the vertical bar 23 is fixedly connected to the pressing strip 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. A micro electric cylinder 25 is installed on the upper surface of the horizontal bar 24, and the outer wall of the micro electric cylinder 25 is fixedly connected to the electroplating suspension hanger 2. The output end of the micro electric cylinder 25 is used to push the horizontal bar 24 to move. The micro electric cylinder 25 is electrically connected to the controller 30, so that the controller 30 can start the micro electric cylinder 25. The micro electric cylinder 25 pushes the horizontal bar 24 downward, the horizontal bar 24 drives multiple vertical bars 23 to move downward synchronously, and the vertical bars 23 drive multiple pressing strips 22 to move downward synchronously, realizing the synchronous downward movement of multiple pressing strips 22.

[0035] In this embodiment, as Figure 2 shown, cathode plug-in terminals 27 are slidably connected to the outer wall of the electroplating suspension hanger 2 and near both ends thereof. The cathode plug-in terminals 27 are fixedly connected to the electroplating tank 1. A positive electrode end 28 is fixedly installed at the bottom end of the inner wall of the electroplating tank 1. Both the positive electrode end 28 and the cathode plug-in terminal 27 are electrically connected to the controller 30. After installation, the lifting hanger 26 is lifted into the electroplating tank 1 by a lifting crane. The lifting hanger 26 drives the electroplating suspension hanger 2 to move downward, and the electroplating suspension hanger 2 is inserted 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 positive electrode end 28, so that the electroplating solution inside the electroplating tank 1 performs electroplating treatment on the interior plastic parts 11. A plurality of delivery pipes 29 are inserted and communicated with one side of the outer wall of the electroplating hanging frame 3. The controller 30 is fixedly located below the top of the delivery pipes 29 on the outer wall of the electroplating tank 1, so as to pour the electroplating solution into the electroplating tank 1 through the delivery pipes 29, and at the same time, the controller 30 can start the micro electric cylinder 25 to perform the driving operation.

[0036] The working principle of the batch mobile electroplating treatment device for automotive interior plastic parts of the present invention is as follows: First of all, when electroplating is installed in batches in the present invention, first, the electroplating solution is poured into the electroplating tank 1 through the delivery pipes 29. At the same time, the inner groove at the top of the interior plastic part 11 is slidably inserted on the outer wall of the top scraping strip 10, and the inner groove in the middle of the interior plastic part 11 is slidably inserted on the inclined surface of the inclined hanging strip 17. At the same time, the inner groove at the bottom of the interior plastic part 11 is inserted on the outer wall of the suspension bottom buckle 15. In this way, a batch of interior plastic parts 11 are all installed. After installation, the lifting hanger 26 is lifted into the electroplating tank 1 by a lifting crane. The lifting hanger 26 drives the electroplating suspension hanger 2 to move downward, and the electroplating suspension hanger 2 is inserted into the inner wall of the cathode plug-in terminal 27.

[0037] Meanwhile, the electroplating suspension hanger 2 immerses multiple electroplating hanging frames 3 in the electroplating bath 1. The multiple electroplating hanging frames 3 drive the trough columns 6, causing the linkage ring 5 to move downward. The linkage ring 5 drives the hanging strip 9, causing the top scraping strip 10 to move downward. The top scraping strip 10 drives the interior plastic part 11 into the electroplating solution inside the electroplating bath 1. Thereby, the controller 30 activates the cathode plug 27, and at the same time, the controller 30 opens the anode end 28. This enables the cathode plug 27 to conduct electricity to the electroplating suspension hanger 2. The electroplating suspension hanger 2 conducts electricity to the multiple electroplating hanging frames 3. The electroplating hanging frames 3 conduct electricity to the trough columns 6. The trough columns 6 conduct electricity to the linkage ring 5. The linkage ring 5 conducts electricity to the hanging strip 9. The hanging strip 9 conducts electricity to the top scraping strip 10. The top scraping strip 10 performs electroplating treatment on the interior plastic part 11. Among them, the hanging strip 9, the linkage ring 5, and the convex block 8 are integrally formed. At the same time, the contact parts of the top scraping strip 10 with the interior plastic part 11, the contact parts of the inclined hanging strip 17 with the interior plastic part 11, and the contact parts of the suspension bottom buckle 15 with the interior plastic part 11 are all blocked and not exposed for electroplating treatment.

[0038] Secondly, when the present invention performs multi-point synchronous displacement electroplating on the top inner groove, the electroplating suspension hanger 2 supports the micro electric cylinder 25. The controller 30 activates the micro electric cylinder 25. The micro electric cylinder 25 pushes the cross bar 24 downward. The cross bar 24 drives multiple vertical bars 23 to move downward synchronously. The vertical bars 23 drive multiple pressing bars 22 to move downward synchronously. The pressing bars 22 slide downward along the inner wall of the sliding groove 21. The pressing bars 22 squeeze downward on multiple groups of arc-shaped elastic pieces 4. The number of each group of arc-shaped elastic pieces 4 is two and they are symmetrically arranged. Thus, the pressing bars 22 squeeze downward on two adjacent arc-shaped elastic pieces 4. The tops of the two arc-shaped elastic pieces 4 are both stressed and squeezed downward, while the bottoms of the two arc-shaped elastic pieces 4 move closer to each other. The arc-shaped elastic pieces 4 drive the linkage ring 5 to move. The linkage ring 5 drives the convex block 8 to move. The convex block 8 moves along the inside of the guiding groove 7 for guiding. At the same time, the two linkage rings 5 move closer to each other along the outer wall of the trough column 6. The linkage ring 5 drives the hanging strip 9 to move. The hanging strip 9 drives the top scraping strip 10 to move. Two adjacent top scraping strips 10 move closer to each other along the top inner groove of the interior plastic part 11. Thus, the parts of the top scraping strip 10 that were initially in contact and blocked with the interior plastic part 11 are fully exposed in the electroplating solution, enabling full contact with the electroplating solution for electroplating operations.

[0039] At the same time, when the present invention performs synchronous displacement on 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. The linkage ring 5 will drive the connecting strip 13 to move leftward. The connecting strip 13 drives the bottom strip 14 to move leftward. The bottom strip 14 will slide for displacement along the bottom inner groove of the interior plastic part 11. The contact part of the bottom strip 14 with the bottom inner groove of the interior plastic part 11 starts to move and displace. Thus, the parts of the suspension bottom buckle 15 that were initially in contact and blocked with the interior plastic part 11 are fully exposed in the electroplating solution, enabling full contact with the electroplating solution for electroplating operations.

[0040] Meanwhile, when the middle inner groove of the present invention undergoes synchronous displacement electroplating, when the connecting bar 13 moves leftward, it will drive the sliding bar 16 to move leftward. The sliding bar 16 drives the inclined hanging bar 17 to tilt and move upward to the left. The inclined hanging bar 17 slides along the outer wall of the sliding bar 16 at the same time, and the inclined hanging bar 17 drives the inclined sleeve 18 to tilt and move upward to the left. The inclined sleeve 18 moves upward to the left along the outer wall of the inclined column 19, and the inclined sleeve 18 moves upward to the left along the inner wall of the inclined frame 20. At the same time, the electroplating hanging frame 3 supports the inclined frame 20 to increase the stability of the inclined frame 20, and the inclined frame 20 supports the inclined column 19 to increase the stability of the inclined column 19. In this way, the inclined hanging bar 17 undergoes an inclined upward displacement to the left in the middle inner groove of the interior plastic part 11, and the contact part between the inclined hanging bar 17 and the middle inner groove of the interior plastic part 11 starts to move and displace. As a result, the part that was initially blocked by the contact between the inclined hanging bar 17 and the interior plastic part 11 is fully exposed in the electroplating solution, enabling the electroplating solution to make full contact for electroplating operations.
