Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating removal technology, specifically a PVD coating removal device. Background Technology
[0002] In the industrial manufacturing field, PVD coating technology is widely used in the processing and production of cutting tools, molds, precision parts, and other products because it can improve the surface hardness, wear resistance, and corrosion resistance of parts. However, during the PVD coating process, there are often problems such as uneven coating thickness, coating composition not meeting requirements, and defects on the surface of parts. At this time, it is necessary to remove the PVD coating from the surface of the parts so that the coating process can be repeated or the parts can be recycled and reused. Therefore, PVD coating removal equipment has become a key auxiliary equipment in industrial production.
[0003] Currently, existing PVD coating removal devices on the market have many technical problems when performing removal operations on small cylindrical parts:
[0004] Traditional stripping devices mostly adopt a fixed immersion stripping structure, which makes it difficult to flexibly adjust the immersion depth of parts in the stripping solution according to the specifications of the parts and the stripping requirements. This results in incomplete removal of the coating on some parts, or damage to the substrate of the parts due to over-immersion, affecting the subsequent performance of the parts. During the stripping process, the stripping solution is in a static state, and the contact and reaction efficiency between the stripping agent and the coating on the surface of the parts is low, which easily leads to local coating residue and uneven stripping.
[0005] After demolding, the parts usually need to be manually transferred to cleaning equipment for cleaning, and then transferred to drying equipment for drying. The process is cumbersome and time-consuming, which reduces the overall production efficiency.
[0006] According to the description of a PVD coating removal device published on the patent website (authorization announcement number: CN216919382U), the PVD coating removal device includes a "cylinder, a rotary electric cylinder", etc., to realize the removal work.
[0007] Regarding the above description, the applicant believes the following issues exist:
[0008] This PVD coating stripping device utilizes a cylinder and a rotary electric cylinder to perform the stripping operation. During use, the object to be stripped is placed inside the cylinder. After stripping, the electric telescopic rod extends and retracts to lift the partition plate onto the cylinder for drying. Natural drying is inefficient and affects subsequent production efficiency. Furthermore, it cannot clean the surface of the parts, impacting the quality of subsequent processing. Additionally, the electric telescopic rod comes into contact with the stripping liquid, affecting the equipment's lifespan. Therefore, improvements to this device are necessary. Utility Model Content

[0019] 1. This PVD coating stripping device, through its stripping mechanism, when stripping small cylindrical parts is required, firstly, according to the composition of the stripping solution, stripping liquid, strong acid solution, or alkaline solution is added to the stripping tank, and clean water is added to the cleaning tank.

[0038] The stirring shaft 296 is located at the bottom of the placement frame 292. Two sets of first hydraulic cylinders 23 and movable seats 26 are provided and symmetrically distributed on the front and rear sides of the bottom of the fixed frame 27, so as to facilitate the movement of movable seats 26 and fixed frame 27 by the first hydraulic cylinders 23.
[0039] Two sets of second hydraulic cylinders 28 are provided and symmetrically distributed on the front and rear sides of the top of the connecting seat 29.

[0040] Example 2
[0041] Please see Figure 1-7Furthermore, based on Embodiment 1, the blower mechanism 3 further includes a fixed base 31, which is fixedly connected to the left side of the base 1. A blower body 32 is fixedly connected to the top of the fixed base 31. A filter cover 33 is threadedly connected to the outer periphery of the top of the blower body 32.

[0043] In actual operation, when this device is used and it is necessary to remove the film from small cylindrical parts, first, according to the composition of the film, the film removal liquid, strong acid solution or alkaline solution is put into the film removal tank 24, and clean water is added to the cleaning tank 21. The parts are placed at the bottom of the placement frame 292. The first hydraulic cylinder 23 drives the moving seat 26 and the fixed frame 27 to move left and right, so that the placement frame 292 is located at the top of the film removal tank 24. At the same time, the second hydraulic cylinder 28 drives the connecting seat 29, the connecting arm 291 and the placement frame 292 to move downward, so that the placement frame 292 and the parts are immersed in the film removal liquid. The immersion depth of the parts in the film removal liquid is adjusted, and the film removal work can be carried out.
[0044] During the demolding process, the servo motor 294 drives the rotating rod 295 and the stirring shaft 296 to rotate, which can stir the demolding liquid in the demolding tank 24. The fluid dynamics generated by stirring can enhance the contact and reaction efficiency between the demolding agent and the coating on the surface of the part, ensuring that the coating on each part can be removed evenly and improving the demolding quality.
[0045] When the rotating rod 295 rotates, it will rotate inside the protective cylinder 293. The protective cylinder 293 can support and protect the rotating rod 295, preventing impurities in the stripping liquid from entering the rotating connection and affecting the motor transmission effect, and extending the service life of the servo motor 294 and the rotating components.

Then, under the action of the first hydraulic cylinder 23 and the second hydraulic cylinder 28, the connecting seat 29, connecting arm 291 and placement frame 292 are moved to the top of the cleaning box 21 and into the cleaning box 21. The placement frame 292 and the parts are completely immersed in clean water for cleaning to ensure the quality of the parts. After cleaning, the second hydraulic cylinder 28 drives the placement frame 292 to move to the vicinity of the air box 35.
[0047] The blower body 32 sends air to the air box 35 through the conveying pipe 34. The air box 35 is fixed inside the left end of the cleaning box 21 and can directly blow and dry the cleaned parts, shorten the drying time of the parts, and avoid water stains from affecting subsequent processes. The filter cover 33, which is threaded on the top of the blower body 32, can filter the air entering the blower, remove dust, impurities and other particles from the air, prevent them from adhering to the surface of the parts during the blowing process, ensure the cleanliness of the parts after demolding, reduce subsequent cleaning steps, and facilitate the cleaning of the filter cover 33, ensuring the air intake and filtration effect.
