It is composed of many sections of insulating rings (generally insulating materials are ceramics or glass) and multiple thin metal electrodes stacked alternately. The insulating rings of the glass substrate and the metal electrodes are generally connected by organic adhesive bonding, and the insulating rings of the ceramic substrate and the metal electrodes are generally welded by metal-ceramic welding process.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0023] In order to evenly apply adhesive on the ceramic ring used in the accelerating tube, a ceramic ring adhesive coating device for the accelerating tube is provided. Figure 1 As shown, it includes a ceramic ring chuck 1, a first fixing mechanism 2 for fixing the ceramic ring chuck 1, a glue groove limiting mechanism 3 and a second fixing mechanism 4 for fixing the glue groove limiting mechanism 3, the first fixing mechanism 2 includes a first motor 5 for driving the ceramic ring chuck 1 to rotate, the first motor 5 is preferably a stepping motor, the glue groove limiting mechanism 3 includes an outer limiting groove block 7 and an inner limiting groove block 8 symmetrically arranged on the inner and outer sides of the ceramic ring 6, the outer limiting groove block 7 radially extends an outer ring limiting groove lip 9 toward the ceramic ring 6, the inner limiting groove block 8 radially extends an inner ring limiting groove lip 10 toward the ceramic ring 6, the outer ring limiting groove lip 9 and the inner ring limiting groove lip 10 form a glue groove 11 for glue coating on the ceramic ring 6, and the height of the glue groove 11 is determined by the thickness of the inner ring limiting groove lip 10 and the outer ring limiting groove lip 9. In order to meet the bonding requirements of the ceramic ring 6, the outer limit groove block 7 and the inner limit groove block 8 can be customized to adapt to the bonding requirements of ceramic rings of different diameters, sizes and shapes. As a preferred embodiment of the present application, the outer ring limit groove lip 9 is an arc that matches the curvature of the ceramic ring 6, and the inner ring limit groove lip 10 is an arc that matches the curvature of the ceramic ring 6.

[0024] The steps of using the accelerating tube ceramic ring gluing device described in the present application are as follows: the ceramic ring 6 is placed on the ceramic ring chuck 1, and the first motor 5 drives the ceramic ring chuck 1 to perform low-speed circular motion, so that the coating area of ​​the glue groove 11 formed by the glue groove limiting mechanism 3 can form an annular coating area on the end face of the ceramic ring 6, and a gluing device is arranged at the glue groove 11. The gluing device can be an automatic gluing device or a manual gluing device. The gluing device continuously fills the glue groove 11 with adhesive, and a scraper is arranged at the glue groove 11. The scraper can be an automatic scraper or a manual scraper. The scraper can scrape off excess adhesive. Finally, an adhesive strip with uniform height and width is formed on the end face of the ceramic ring 6, which is convenient for subsequent gluing operations with an external motor.

[0025] In this application, if Figure 1 and Figure 2As shown, the second fixing mechanism 4 includes a second motor 12 for driving the glue groove limiting mechanism 3 to move up and down and a fixing unit 13 for fixing the glue groove limiting mechanism 3, and the fixing unit 13 is arranged on the second motor 12. As a preferred embodiment of the present application, the second motor 12 is a through-axis linear stepper motor, and the second stepper motor is arranged on a fixed support with a sliding screw. The through-axis linear stepper motor moves up and down on the sliding screw, thereby driving the fixing unit 13 to move up and down, and finally realizing the up and down movement of the glue groove limiting mechanism 3, and assisting in forming a coating area on the ceramic ring 6. In addition, the glue groove limiting mechanism 3 is set to an up and down movement structure mode, and this structural design can coat ceramic rings 6 of different heights.

[0026] In this application, if Figure 1 As shown, the fixing unit 13 includes an adjustable position fixing bracket 14 for moving the glue groove limiting mechanism 3 left and right, a vertical bracket 15 and a horizontal support rod 16 for fixing the outer limit groove block 7 and the inner limit groove block 8, the adjustable position fixing bracket 14 is slidably connected to the vertical bracket 15, and the vertical bracket 15 is fixedly connected to the horizontal support rod 16. This structural design can make the glue groove limiting mechanism 3 move left and right as a whole, which is convenient for gluing ceramic rings of different diameters. In the present application, because the ceramic ring 6 is a brittle and crackable component, the ceramic ring chuck 1 can be set to different diameter sizes. When in use, different ceramic ring chucks 1 are replaced for ceramic rings of different diameter sizes. Compared with the ceramic ring chuck 1 that can automatically change the size, it can better protect the ceramic ring 6 from being damaged.

[0027] In this application, if Figure 1 As shown, the outer limit groove block 7 moves left and right on the horizontal support rod 16, and the inner limit groove block 8 moves left and right on the horizontal support rod 16. When the outer limit groove block 7 moves left and right, the outer ring limit groove lip 9 moves left and right with the outer limit groove block 7. When the inner limit groove block 8 moves left and right, the inner ring limit groove lip 10 moves left and right with the inner limit groove block 8, thereby adjusting the width of the glue groove 11. This structural design can apply adhesive to ceramic rings 6 of different thicknesses. First nuts 17 for fixing the outer limit slot block 7 and cooperating with the horizontal support rod 16 are provided on both sides of the outer limit slot block 7. The first nut 17 can fix the outer limit slot block 7 to the horizontal support rod 16, thereby preventing the outer limit slot block 7 from shaking during the movement of the ceramic ring 6; second nuts 18 for fixing the inner limit slot block 8 and cooperating with the horizontal support rod 16 are provided on both sides of the inner limit slot block 8. The second nut 18 can fix the inner limit slot block 8 to the horizontal support rod 16, thereby preventing the inner limit slot block 8 from shaking during the movement of the ceramic ring 6.

[0028] In this application, if Figure 3 and Figure 4 As shown, a first guide wheel 19 is provided at the lower part of the outer limit groove block 7 to prevent the ceramic ring 6 from shaking radially, and a second guide wheel 20 is provided at the lower part of the inner limit groove block 8 to prevent the ceramic ring 6 from shaking radially. In order to further prevent the glue groove limiting mechanism 3 from rotating with the ceramic ring or preventing the ceramic ring from shaking radially, a first guide roller 21 is provided at the lower part of the outer limit groove block 7 to cooperate with the first guide wheel 19 to prevent the ceramic ring 6 from shaking radially, and a second guide roller 22 is provided at the lower part of the inner limit groove block 8 to cooperate with the second guide wheel 20 to prevent the ceramic ring 6 from shaking radially. The first guide wheel 19, the second guide wheel 20, the first guide roller 21 and the second guide roller 22 jointly enable the outer ring limit groove lip 9 and the inner ring limit groove lip 10 to accurately form a coating area on the ceramic ring 6. Preferably, when the outer ring limit groove lip 9 is arc-shaped and the inner ring limit groove lip 10 is also arc-shaped, calculation is performed to form an arc groove of a certain area on the end face of the ceramic ring after the inner and outer arcs are positioned. When the ceramic ring makes a circular motion, the arc groove can form an annular adhesive coating area of ​​the size required by the process on the end face of the ceramic ring.

[0029] In this application, if Figure 5 As shown, Figure 1 In the enlarged view of the area A in the middle, a ceramic ring radial positioning end face 23 and a ceramic ring clamping positioning end face 24 are provided on the ceramic ring chuck 1 for quickly positioning the ceramic ring 6. The ceramic ring radial positioning end face 23 and the ceramic ring clamping positioning end face 24 are formed by vertical annular protrusions arranged on the ceramic ring chuck 1 and perpendicular to the end face of the ceramic ring chuck 1. The ceramic ring radial positioning end face 23 and the ceramic ring clamping positioning end face 24 enable the ceramic ring 6 to be quickly positioned and placed on the ceramic ring chuck 1. A ceramic ring retaining spring 25 for fixing the ceramic ring 6 is provided on the ceramic ring chuck 1. After being fixed by the ceramic ring retaining spring 25, the ceramic ring 6 can rotate with the ceramic ring chuck 1. There are at least two ceramic ring retaining springs 25. Since the ceramic ring 6 is annular, the ceramic ring retaining springs 25 need to be evenly distributed on the inner ring of the ceramic ring. As a preferred embodiment of the present application, as Figure 4 As shown, the number of the ceramic ring retaining springs 25 is four.

[0030] In summary, the present application designs a glue coating device for an accelerating tube ceramic ring, comprising a ceramic ring chuck 1, a first fixing mechanism 2 for fixing the ceramic ring chuck 1, a glue groove limiting mechanism 3 and a second fixing mechanism 4 for fixing the glue groove limiting mechanism, wherein the first fixing mechanism 2 comprises a first motor 5 for driving the ceramic ring chuck 1 to rotate, the glue groove limiting mechanism 3 comprises an outer limiting groove block 7 and an inner limiting groove block 8 symmetrically arranged on the inner and outer sides of a ring-shaped ceramic ring 6, the outer limiting groove block 7 radially extends an outer ring limiting groove lip 9 toward the direction of the ceramic ring 6, the inner limiting groove block 8 radially extends an inner ring limiting groove lip 10 toward the direction of the ceramic ring 6, the outer ring limiting groove lip 9 and the inner ring limiting groove lip 10 form a glue groove 11 for glue coating on the ceramic ring 6. This structural design forms a glue coating area on the end face of the ceramic ring 6 that meets the glue coating process size. After glue coating, a uniform adhesive strip with a certain thickness and width is formed on the end face of the ceramic ring to facilitate subsequent gluing operations with an external motor. The coating work is convenient, fast and efficient.
