Description

Technical Field

[0001] This utility model relates to the field of alumina ceramic surface treatment technology, and in particular to a uniform coating structure of metallizing paste on alumina ceramic surface. Background Technology

[0002] Metallizing paste for alumina ceramics is a functional paste-like material used to form a continuous and robust metal layer on the surface of alumina ceramics. It is a key material for the functionalization of alumina ceramics in fields such as electronic packaging, new energy components, and precision sensors. In traditional alumina ceramic surface metallizing paste coating equipment, screen printing machines are widely used due to their high coating precision.

[0003] Such equipment typically consists of a worktable, a screen printing mechanism (including a scraper and a screen frame), and positioning components. During operation, ceramic parts to be coated are placed individually or in small quantities on the worktable, and the coating is started after the positioning components fix their positions. After coating is completed, the processed ceramic parts need to be manually removed, and new ceramic parts to be processed are placed on top. The entire process is intermittent. Since the next batch of ceramic parts must wait for the previous batch to be coated and removed before loading, the equipment has a long downtime and cannot achieve continuous production. This not only reduces the overall coating efficiency of the metallizing paste but also makes it difficult to meet the needs of mass production. To solve the above problems, this utility model proposes a uniform coating structure for metallizing paste on the surface of alumina ceramics. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a uniform coating structure for metallizing paste on the surface of alumina ceramics, thus solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a uniform coating structure for metallizing paste on the surface of alumina ceramics, comprising: a mounting base plate, a hydraulic cylinder, a lifting frame, a moving truss, and a conveyor frame. A drive assembly is mounted on the side wall of the lifting frame, and a threaded rod is fixedly connected to the output shaft of the drive assembly. The threaded rod is threadedly connected to the moving truss. Two first scrapers are connected to the top of the moving truss via two first electric push rods. A wire mesh frame is mounted on the side wall of the lifting frame via two mounting frames. A placement mechanism for placing ceramics is provided on the conveyor frame. The placement mechanism includes a conveyor belt disposed within the conveyor frame, on which a placement frame is placed. Two limiting plates are fixedly connected to the upper end of the conveyor frame. A controller is mounted on the side wall of the conveyor frame, and a baffle is provided through the side wall of the limiting plate.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] This utility model provides a technical solution:

[0024] Please see Figures 1-5 The alumina ceramic surface is uniformly coated with a metallizing paste, including: a mounting base plate 1, a hydraulic cylinder 2, a lifting frame 3, a moving truss 4, and a conveyor frame 9. A drive assembly 16 is installed on the side wall of the lifting frame 3. The output shaft of the drive assembly 16 is fixedly connected to a threaded rod 11. The threaded rod 11 is threadedly connected to the moving truss 4. There is a protective cover near the threaded rod 11 (not shown in the figure). The threaded rod 11 is regularly lubricated and maintained by dedicated maintenance personnel. In actual operation, the threaded rod 11 can be replaced with an electric slide rail. The top of the moving truss 4 is connected to two first scrapers 6 through two first electric push rods 5. Each of the two first scrapers 6 has a limit rod at its upper end. A screen frame 7 is installed on the side wall of the lifting frame 3 through two mounting frames 8. The two first scrapers 6 are scraper assemblies in existing screen printing machines, and the screen frame 7 is a screen plate assembly in existing screen printing machines. The structure and working principle of both are existing technologies, so they will not be described in detail.

[0025] The conveyor frame 9 is equipped with a placement mechanism for placing ceramics. The placement mechanism includes a conveyor belt 12 installed inside the conveyor frame 9, a placement frame 13 placed on the conveyor belt 12, two limiting plates 15 fixedly connected to the upper end of the conveyor frame 9, a controller 14 installed on the side wall of the conveyor frame 9, a baffle 23 penetrating through the side wall of the limiting plate 15, and a drive device for the conveyor belt 12 (shown in the figure) installed on the side wall of the conveyor frame 9.

[0026] Both sides of the conveyor frame 9 are provided with a drive mechanism for moving the baffle 23. The drive mechanism includes a fixed frame 21 fixedly connected to the side wall of the conveyor frame 9. A third electric push rod 22 is fixedly connected to the inner wall of the fixed frame 21. The output end of the third electric push rod 22 is fixedly connected to the side wall of the adjacent baffle 23, so that the baffle 23 does not need to be pulled manually.

[0027] Furthermore, a guide plate 20 is fixedly connected to the side wall of the limiting plate 15. The guide plate 20 is inclined. The inclined design of the guide plate 20 can guide the placement frame 13 on the conveyor belt 12. When the placement frame 13 moves from both sides of the conveyor belt 12 to the middle limiting plate 15, the inclined surface can slowly correct the position of the placement frame 13, avoiding the placement frame 13 from directly hitting the end of the limiting plate 15, causing jamming or position displacement, ensuring that the placement frame 13 smoothly enters the limiting area and improving the smoothness of conveying.

[0028] Furthermore, a mounting frame 17 is fixedly connected to the side wall of the conveyor frame 9, and a second scraper 19 is installed on the top of the mounting frame 17 via a second electric push rod 18. The second scraper 19 can scrape off excess paste from the surface of the ceramic substrate.

[0029] Furthermore, two vertical rods 10 are fixedly connected to the upper end of the mounting base plate 1. The upper ends of the vertical rods 10 pass through the upper end of the lifting frame 3, so that the lifting frame 3 can only move vertically.

[0030] Furthermore, the wire mesh frame 7 is slidably connected to the mounting frame 8, and the upper end of the mounting frame 8 is provided with multiple locking bolts, which allows the wire mesh frame 7 to be disassembled and maintained.

[0031] In the initial state, hydraulic cylinder 2 is connected to an external hydraulic station.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] The operator places the placement frame 13 containing the ceramic parts to be coated onto the right side of the conveyor belt 12. The conveyor belt 12 rotates under the drive of the drive equipment, conveying the placement frame 13 downwards towards the screen frame 7. When the placement frame 13 contacts the guide plate 20, it enters between the two limit plates 15 under the guidance of the inclined guide plate 20. Then, the third electric push rod 22 drives the baffle 23 to extend, blocking the placement frame 13 from continuing to move. The conveyor belt 12 stops. At this time, the next placement frame 13 containing the ceramic parts to be coated can be placed simultaneously on the right side of the equipment, realizing the material loading preparation.

[0034] After the operator applies a measured amount of metallizing paste to one side of the screen frame 7, the hydraulic cylinder 2 is activated by the controller 14. The output end of the hydraulic cylinder 2 retracts, causing the lifting frame 3 to descend, so that the screen frame 7 fits against the surface of the ceramic part in the placement frame 13. Then, the output end of the first electric push rod 5 retracts, causing the first scraper 6 to descend to fit against the surface of the screen frame 7. The drive assembly 16 is activated and drives the threaded rod 11 to rotate. The threaded rod 11 drives the moving truss 4 to move horizontally, thereby causing the two first scrapers 6 to slide along the surface of the screen frame 7, so that the metallizing paste is evenly coated on the surface of the ceramic part through the screen frame 7.

[0035] After coating is completed, the output end of hydraulic cylinder 2 extends to drive the lifting frame 3 to rise and reset, the first electric push rod 5 extends to drive the first scraper 6 to rise and reset, and the drive assembly 16 drives the moving truss 4 back to the initial position; the third electric push rod 22 drives the baffle 23 to retract, the conveyor belt 12 restarts, and the placed frame 13 where the coated ceramic part is located is transported to the left, while the placed frame 13 to be coated on the right moves below the screen frame 7, and the above coating process is repeated.

[0036] When the coated placement frame 13 moves below the second scraper 19, the second electric push rod 18 adjusts the second scraper 19 to a suitable height. The second scraper 19 scrapes off the excess metallizing paste from the surface of the ceramic part. Finally, the coated placement frame 13 is output from the left side of the conveyor frame 9, and the operator unloads the material, realizing a continuous operation process of "right-side loading - middle coating - left-side unloading".

[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
