Description

Technical Field

[0001] This utility model relates to the field of rotary tooling technology, and in particular to a gradient coating rotary tooling for uniform coating of deep holes in porous tantalum implants. Background Technology

[0002] In the field of biomedical implants, porous tantalum materials are widely used in orthopedic and dental implants, such as artificial joints and bone repair scaffolds, due to their excellent biocompatibility, high porosity and mechanical strength. These implants usually have complex deep-pore structures and require uniform coating of bioactive gradient coatings on the surface to promote bone tissue ingrowth, reduce rejection reactions and enhance functionality.

[0003] Existing gradient coating rotary fixtures for uniform deep-pore coating of porous tantalum implants often employ rigid fixing mechanisms, lacking self-adaptive capabilities. This makes the implants prone to shaking or even detachment due to vibration or centrifugal force, resulting in uneven coating distribution. In particular, for porous tantalum implants, the coating liquid in the deep-pore areas is easily lost or accumulated during shaking, causing inconsistent coating thickness and incomplete pore coverage, affecting biocompatibility and product qualification rate. Therefore, improvements are needed. Utility Model Content

It also includes: two support handles 3 symmetrically disposed on the support cover 2 and fixedly connected to it; a fixing mechanism disposed inside the spin coater 1 to clamp and fix the implant, preventing it from shaking or shifting and affecting the coating process; a fixing frame 4 disposed inside the spin coater 1 and fixedly connected to it; and a cleaning mechanism disposed on the support cover 2 to clean the interior of the spin coater 1, preventing the coating liquid from adhering to the inner wall of the spin coater 1 and making cleaning difficult.

[0027] Reference Figure 5 and Figure 6 In a preferred embodiment, the fixing mechanism includes: a fixing rod 5, disposed within the fixing frame 4 and fixedly connected to the fixing frame 4; a fixing sleeve 6, slidably connected to the fixing rod 5 and also slidably connected to the fixing frame 4; a fixing disc 7, fixedly connected to the fixing sleeve 6; an elastic component, disposed on the fixing sleeve 6; an elastic block 8, disposed on the fixing sleeve 6, fixedly connected to the fixing sleeve 6, and slidably connected to the fixing frame 4; an elastic spring 9, one end of which is fixedly connected to the elastic block 8, and the other end of which is fixedly connected to the fixing frame 4; and a rotating component, disposed on the elastic block 8.

[0028] When in operation, pressing the fixed plate 7 causes the fixed sleeve 6, which is fixedly connected to the fixed plate 7, to slide on the fixed rod 5, causing the elastic block 8, which is fixedly connected to the fixed sleeve 6, to move, causing the elastic spring 9, which is fixedly connected to the elastic block 8, to be compressed, generating elastic potential energy.

[0029] Reference Figure 5 and Figure 6 In a preferred embodiment, the rotating component includes: two first rotating shafts 10, which are symmetrically arranged on the elastic block 8 and fixedly connected to the elastic block 8; a rotating plate 11, which is rotatably connected to the first rotating shafts 10; a second rotating shaft 12, which is rotatably connected to the rotating plate 11; a sliding component, which is disposed on the fixed frame 4; a sliding groove 13, which is formed on the fixed frame 4; two sliding blocks 14, which are symmetrically arranged in the sliding groove 13, slidably connected to the sliding groove 13, and fixedly connected to the second rotating shaft 12; and a sliding frame 15, which is disposed on the sliding blocks 14 and fixedly connected to the sliding frame 15.

[0030] During operation, the rotating plate 11, which is rotatably connected to the first rotating shaft 10, rotates, thereby causing the sliding block 14, which is fixedly connected to the second rotating shaft 12, to slide in the sliding groove 13, so that the sliding blocks 14 move away from each other, thereby causing the sliding frame 15, which is fixedly connected to the sliding block 14, to move.

[0031] Reference Figure 4 In a preferred embodiment, the cleaning mechanism includes: a cleaning frame 16, which is disposed on the support cover 2 and fixedly connected to the support cover 2; a cleaning motor 17, which is fixedly connected to the cleaning frame 16; a cleaning shaft 18, which is fixedly connected to the output end of the cleaning motor 17 and rotatably connected to the support cover 2; and a connecting component disposed on the cleaning shaft 18.

[0032] During operation, the cleaning motor 17 is started, which drives the cleaning shaft 18, which is fixedly connected to the output end of the cleaning motor 17, to rotate on the support cover 2.

[0033] Reference Figure 4 In a preferred embodiment, the connecting component includes: a connecting sleeve 19, which is disposed on the cleaning shaft 18 and fixedly connected to the cleaning shaft 18; a connecting rod 20, which is disposed on the connecting sleeve 19 and fixedly connected to the connecting sleeve 19; and two cleaning sponges 21, which are symmetrically disposed on the connecting rod 20 and fixedly connected to the connecting rod 20.

[0034] During operation, the connecting sleeve 19, which is fixedly connected to the cleaning shaft 18, rotates, causing the connecting rod 20, which is fixedly connected to the connecting sleeve 19, to rotate on the inner wall of the spin coater 1, so that the cleaning sponge 21, which is fixedly connected to the connecting rod 20, absorbs and cleans the coating liquid adhering to the inner wall of the spin coater 1.

[0035] Working principle: In use, first press the fixed plate 7, which causes the fixed sleeve 6, which is fixedly connected to the fixed plate 7, to slide on the fixed rod 5. This causes the elastic block 8, which is fixedly connected to the fixed sleeve 6, to move. This causes the elastic spring 9, which is fixedly connected to the elastic block 8, to be compressed, generating elastic potential energy. This causes the rotating plate 11, which is rotatably connected to the first rotating shaft 10, to rotate. This causes the sliding block 14, which is fixedly connected to the second rotating shaft 12, to slide in the sliding groove 13. This causes the sliding blocks 14 to move away from each other, thereby causing the sliding frame 15, which is fixedly connected to the sliding block 14, to move. Then, the implant to be coated is placed on the fixed frame 4. Then, the fixed plate 7 is slowly released, causing the elastic spring 9 to release its elastic potential energy until the sliding frame 15 contacts the edge of the implant. This clamps and fixes the implant, preventing it from shaking or falling off. Then, when the spin coater 1 is started, the cleaning motor 17 is started at the same time, which drives the cleaning shaft 18, which is fixedly connected to the output end of the cleaning motor 17, to rotate on the support cover 2. This causes the connecting sleeve 19, which is fixedly connected to the cleaning shaft 18, to rotate, which drives the connecting rod 20, which is fixedly connected to the connecting sleeve 19, to rotate on the inner wall of the spin coater 1. This causes the cleaning sponge 21, which is fixedly connected to the connecting rod 20, to absorb and clean the coating liquid adhering to the inner wall of the spin coater 1, thereby cleaning the coating liquid adhering to the inner wall of the spin coater 1.

[0036] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
