[0021] Figure 3 This is a top view of the structure of an embodiment. Detailed Implementation

[0022] See appendix Figure 1-3 This describes a specific structure of the present invention. The metallization coating device for the outer circumference of the disc-shaped ceramic part includes a worktable 2 with handles 1 at both ends. The worktable 2 includes the following mechanism:

[0023] The system includes a product fixture tray 11 and a printing fixture tray 6 arranged side-by-side. The product fixture tray 11 is driven to rotate by a product motor 20, and the printing fixture tray 6 is driven to rotate by a printing motor 3. A disc-shaped ceramic component 10 is concentrically fixed to the product fixture tray 11 and moves synchronously. The product fixture tray 11 and the printing fixture tray 6 are matched and replaced according to the specifications of the disc-shaped ceramic component 10. In the example, the disc-shaped ceramic component 10 has concentric circular steps; in other embodiments, it may also be a disc-shaped ceramic component without concentric circular steps.

[0024] In the example, the printing fixture disk 6 and its printing motor 3 are fixedly mounted on the worktable 2. The lower end of the printing fixture disk 6 is immersed in the paste in the paste box 21 below. In the example, the paste box 21 is provided with a paste adjustment component for adjusting the vertical distance between the inner bottom surface of the paste box and the outer circular surface of the printing fixture disk 6. The paste adjustment component in the example includes a base 22 supporting the paste box 21, which is fixedly mounted on the worktable 2. A limiting groove 23 is provided on the front side of the base 22, and the ear plate 25 fixed to the paste box is inserted into the limiting groove 23. The screw of the lifting knob 8 is threadedly connected to the screw hole on the ear plate 24. When the lifting knob 8 is turned forward / reverse, the paste box 21 is lifted or lowered through the ear plate 24. The base 22 is also provided with a long groove 25, through which the screw of the paste locking knob 9 passes to lock the position of the paste box 21. The long groove facilitates the locking operation of the locking knob along its adjustment position. The height of the paste box 21 can be easily adjusted and locked according to the model of the printing jig tray 6 by means of the paste adjustment component, so that the paste can be properly adhered to the printing jig tray 6.

[0025] A doctor blade 7 is provided on one side of the printing fixture disk 6. The printing fixture disk 6 is inserted into the doctor blade groove 701 of the doctor blade 7. The doctor blade 7 is provided with a doctor blade adjustment assembly for adjusting the distance between the doctor blade 7 and the outer circular surface of the printing fixture disk 6. In this example, the doctor blade adjustment assembly includes a doctor blade micrometer head 5 and a doctor blade sliding seat 702 mounted on the worktable, and a doctor blade locking knob 4. The doctor blade sliding seat 702 is connected to the doctor blade 7. The probe end of the doctor blade micrometer head 5 drives the doctor blade sliding seat 702 to reciprocate in the direction toward the printing fixture disk 6 to adjust its position. After the position is adjusted to the correct position, the position is locked by the doctor blade locking knob 4.

[0026] The doctor blade 7 in the example has four doctor blade grooves 701 of different specifications. After replacing the printing fixture disk 7, the doctor blade grooves 701 can be replaced by disassembling and assembling the doctor blade 4. The corresponding doctor blade groove 701 on the doctor blade 4 is used according to the different models of the printing fixture disk 7. Then, the distance between the doctor blade 4 and the printing fixture disk 7 is adjusted by the doctor blade adjustment component, so that the doctor blade can be used to perform doctor blade operation on the outer wall of different models of printing fixture disks 7.

[0027] The micrometer head is a high-precision adjustment device, mainly used to achieve micron-level position or angle adjustments, and is widely used in precision machining, measurement, and mechanical control. The immovable part consists of a bushing and a mounting sleeve forming a stable base support and mounting reference. The movable part includes a measuring rod, a micrometer drum, and a fine-tuning knob. The measuring rod directly contacts the workpiece and transmits displacement changes through axial movement; the micrometer drum is a rotating component with precise graduations, achieving micron-level displacement adjustment through rotation; the fine-tuning knob is a manually operated knob used for finely adjusting the measuring rod position. The micrometer head drives the measuring rod to move linearly by rotating the micrometer drum, and its minimum adjustment accuracy can reach the micron level, hence it is also called a "micrometer head" or "micrometer head".

[0028] The product fixture disk 11 and the product motor 20 are mounted on the base plate 18 of the moving platform 16; the base plate 18 is provided with a front-to-back adjustment component for adjusting the front-to-back distance between the product fixture disk 11 and the printing fixture disk 6, and a left-to-right adjustment component for adjusting the left-to-right distance between the product fixture disk 11 and the printing fixture disk 6; the moving platform 16 is provided with a feeding component that causes the outer circular surface of the disc-shaped ceramic part 10 to abut against the outer circular surface of the printing fixture disk 6.

[0029] In the example, the left and right adjustment assembly includes a left and right micrometer head 13 and a left and right sliding seat 27, and a left and right locking knob 12, all mounted on the mobile platform 16. A front and back adjustment assembly is mounted on the left and right sliding seat 27. The front and back adjustment assembly includes a front and back micrometer head 19 and a front and back sliding seat 26, and a front and back locking knob 17, all mounted on the left and right sliding seat 27. The probe end of the left and right micrometer head 13 drives the left and right sliding seat 27 to move in the left and right direction, and the probe end of the front and back micrometer head 19 drives the front and back sliding seat 26 to move in the front and back direction.

[0030] After adjusting the left-right distance between the product fixture plate 11 and the printing fixture plate 6 using the left-right adjustment component, lock the position using the left-right locking knob 12. After adjusting the front-back distance between the product fixture plate 11 and the printing fixture plate 6 using the front-back adjustment component, lock the position using the front-back locking knob 17. Then operate the feed component to perform the coating operation.

[0031] In this example, the feeding assembly includes a feed microhead 15 and a return spring 14 mounted on the worktable 2. The moving platform 16 is mounted on the worktable 2 via a feed guide rail 28 and its sliding seat. The probe end of the feed microhead 15 abuts against the side of the moving platform 16. When the probe rotates forward, it drives the moving platform 16 toward the printing fixture disk 6, so that the outer surface of the disc-shaped ceramic part 10 abuts against the outer surface of the printing fixture disk 6, thereby completing the coating operation. When the probe rotates in the reverse direction, the return spring 14 drives the moving platform 16 to move in the reverse direction to reset, so that after adjusting the position, the concentric circular steps of different radii on the disc-shaped ceramic part 10 can be coated one by one. Alternatively, the product can be removed and replaced for further work.

[0032] As can be seen from the above, this coating device can accurately and reliably complete the metallization coating work on the outer circumference of the disc-shaped ceramic part. Compared with the existing technology, it effectively reduces the workload and improves the production efficiency, and effectively improves the uniformity of the product coating and the stability of the coating quality.
