Description

Technical Field

[0001] This utility model relates to the field of resist plating technology for sub-instrument panels, specifically a resist plating device for electroplated sub-instrument panels. Background Technology

[0002] In the automotive interior manufacturing industry, the surface treatment process of the sub-dashboard electroplated parts is crucial. As consumers' requirements for the quality of automotive interiors continue to increase, electroplated parts not only need to have good wear resistance and corrosion resistance, but also need to present an exquisite and beautiful appearance. However, during the electroplating process, some areas of the sub-dashboard electroplated parts do not need to be electroplated. This requires the use of resist plating technology to prevent these areas from being covered by the electroplating solution.

[0003] Chinese utility model patent CN219356724U discloses a resist plating device for sub-instrument panel electroplating parts, including a storage box. The storage box has a mounting plate at its bottom cavity, and several paint spray tubes arranged in a matrix are connected through the bottom of the storage box. Pins are provided at the bottom of the mounting plate corresponding to the positions of the paint spray tubes, and the pins are matched to the diameter of the paint spray tubes. This utility model uses an electromagnet that is energized to attract a permanent magnet. The permanent magnet drives the pins upward, causing them to move out of the paint spray tubes, allowing the resist plating paint to flow out. This enables resist plating of automotive sub-instrument panels. After resist plating, the electromagnet is de-energized, and the permanent magnet, mounting plate, and pins move downward simultaneously, causing the pins to re-enter the paint spray tubes and seal them. This effectively prevents the resist plating paint from drying out and clogging the paint spray tubes after prolonged storage, facilitating future use.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: On the one hand, in the above-mentioned electroplating resist plating device, the pin is opened and closed by an electromagnet and a permanent magnet in combination to lift the paint spray tube. However, when opened, there will be residual resist plating liquid on the surface of the pin. When the resist plating liquid solidifies, it seriously affects the quality of subsequent resetting and closing. On the other hand, in the above-mentioned solution, a sponge is provided at the bottom of the mounting plate. Although it can achieve a uniform coating effect, the paint liquid inside the sponge will solidify, which seriously affects the efficiency of the subsequent resist plating process. Therefore, we propose a resist plating device for sub-instrument panel electroplating parts. Utility Model Content

[0027] Furthermore, the two opposite sidewalls of the paint storage box 1 are provided with two U-shaped adjustment grooves 9 distributed symmetrically on the outside. The U-shaped adjustment grooves 9 are U-shaped. The top of the two U-shaped adjustment grooves 9 are provided with connecting rods 7, and the connecting rods 7 are provided with fixing holes 8. By releasing the fixing rods 3 from fixing the anti-clogging pin row 2 to the paint storage box 1, the slider 16 of the anti-clogging pin row 2 slides along the inside of the U-shaped adjustment groove 9 until it slides to the other end of the U-shaped adjustment groove 9, and is fixed again by the fixing rods 3, so as to realize the opening and flow or the closing and sealing of the paint spray head 10.

[0028] Furthermore, the bottom of the paint storage box 1 is provided with a set of spray nozzles 10 arranged at equal intervals, and the spray nozzles 10 are connected to the interior of the paint storage box 1. The side wall of the spray nozzles 10 is provided with a set of pin placement holes 11, and the set of pin placement holes 11 is arranged in the same way as the set of spray nozzles 10. The spray nozzles 10 and the pin placement holes 11 are arranged in a cross pattern, and the pin placement holes 11 are provided with multiple cleaning rings 17 arranged at equal intervals. The cleaning rings 17 can scrape the paint on the surface of the pins 13 to ensure that there is no solidified paint on the surface of the pins 13, effectively ensuring the subsequent sealing effect of the spray nozzles 10.

[0029] Furthermore, the anti-clogging pin bar 2 has two sliders 16 arranged symmetrically on its two opposite side walls. The sliders 16 are slidably connected to the U-shaped adjustment groove 9.

[0036] Mounting bracket 5: Mounting bracket 5 is located on the top of paint storage box 1, with connection holes 6 at the four corners. The paint storage box 1 is fixed to the designated position on the production line by bolts and other connectors, providing installation support.

[0037] Connection holes 6: Connection holes 6 are distributed at the four corners of the mounting bracket 5 and are used to insert bolts or screws to connect the paint storage box 1 to the production line bracket and other fixed structures to ensure that the device is installed stably.

[0038] Connecting rod 7: Connecting rod 7 spans the U-shaped adjustment groove 9 at the top of paint storage box 1, and has a fixing hole 8 inside. It cooperates with fixing rod 3 to help fix the anti-clogging pin row 2 at a specific position in the U-shaped adjustment groove 9.

[0039] Fixing hole 1 8: Fixing hole 1 8 is located inside the connecting rod 7 and is concentric with fixing hole 2 15 of the anti-clogging pin row 2, allowing the fixing rod 3 to pass through, thereby locking the paint storage box 1 and the anti-clogging pin row 2.

[0040] U-shaped adjustment groove 9: The U-shaped adjustment groove 9 is symmetrically arranged on both sides of the paint storage box 1, and has a U-shaped structure. It cooperates with the slider 16 of the anti-clogging pin bar 2 to guide the pin bar to slide.

[0041] Spray head 10: The spray head 10 is evenly distributed at the bottom of the paint storage box 1 and is connected to the inside. It controls the spraying of the resist paint liquid and is the key component for paint liquid output.

[0042] Pin placement hole 11: Pin placement hole 11 is located on the side wall of paint spray head 10 and is distributed intersectingly with paint spray head 10. A cleaning ring 17 is provided inside to collect pins 13 and scrape off residual paint on their surface.

[0043] Support plate 12: The support plate 12 is welded to the bottom of the anti-clogging pin row 2, with pins 13 evenly distributed on it. When the pin row slides, it drives the pins 13 to move, thereby opening and resetting the paint spray head 10.

[0044] Pin 13: Pin 13 is installed on the top of support plate 12 and cooperates with paint spray head 10 and pin placement hole 11. It controls the flow of paint and accepts cleaning ring scraping by sliding to close and block paint spray head 10 or inserting into pin placement hole 11.

[0045] Handle 14: Handle 14 is located on both sides of the anti-clogging pin bar 2, allowing the operator to push and pull the pin bar and slide along the U-shaped adjustment groove 9 for convenient operation;

[0046] Fixing Hole 2 15: Fixing Hole 2 15 is located at the top of the anti-clogging pin row 2 and is concentric with Fixing Hole 1 8. It works with the fixing rod 3 to lock the position of the pin row and ensure structural stability during resist plating.

[0048] Cleaning ring 17: The cleaning ring 17 is evenly distributed inside the pin placement hole 11. It is made of soft and elastic material. When the pin 13 is inserted, it scrapes off the residual paint on the surface to prevent the paint from hardening and affecting the performance of the device.

[0049] Working principle: Install the anti-plating device for the sub-instrument panel electroplating parts correctly according to the diagram. When using the anti-plating device for the sub-instrument panel electroplating parts, first fix the paint storage box 1 in the designated position of the electroplating production line through the connection holes 6 at the four corners of the mounting bracket 5. Inject the anti-plating paint liquid into the paint storage box 1 through the paint inlet 4. The paint liquid is stored for later use through the spray nozzle 10 at the bottom of the paint storage box 1. When it is necessary to perform anti-plating treatment on the sub-instrument panel electroplating parts, the operator holds the handles 14 on both sides of the anti-clogging pin row 2 to release the fixing rod 3 from fixing the paint storage box 1 and the anti-clogging pin row 2. At this time, the anti-clogging pin row 2 slides along the U-shaped adjustment groove 9 on the side wall of the paint storage box 1 through the slider 16 and moves away from the paint storage box 1. During the movement of the anti-clogging pin row 2, the pins 13 on its bottom support plate 12 are gradually pulled out from the spray nozzle 10 and aligned with the pin placement hole 11. The pins 13 are inserted. After the pin placement hole 11 contacts, the pin 13 is cleaned by scraping paint inside the pin placement hole 11 to remove residual resist paint and prevent the paint from solidifying and affecting the reset and sealing effect of the pin 13. At this time, the paint spray head 10 can perform resist painting on the sub-instrument panel, evenly applying it to the non-electroplated areas of the electroplated parts of the sub-instrument panel. After resist painting is completed, push the handle 14 in the opposite direction to make the anti-clogging pin row 2 slide along the U-shaped adjustment groove 9 towards the paint storage box 1. The pin 13 is withdrawn from the pin placement hole 11 and inserted into the paint spray head 10 to prevent the paint from continuing to flow out and solidify. When the anti-clogging pin row 2 is reset to the initial position, the fixing hole 1 8 and the fixing hole 2 15 are aligned again, and the fixing rod 3 is inserted to complete the locking. The whole process achieves the precise opening and closing of the paint spray head through mechanical sliding and the scraping action of the cleaning ring, while avoiding paint blockage and pin adhesion problems.
