DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example 1: Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a coating and positioning device for the end face of a ceramic vacuum tube, comprising a coating machine 1 and a coating unit 2 arranged on the coating machine 1, two supporting mounting plates 3 are arranged on one side of the coating machine 1 close to the coating unit 2, a feed conveyor belt 4 is arranged between the two supporting mounting plates 3, a material guiding mechanism 5 located above the feed conveyor belt 4 is arranged on the inner walls of the two supporting mounting plates 3, and a positioning gap 6 is left between the feed conveyor belt 4 and the coating machine 1, and a positioning component 7 for positioning the ceramic vacuum tube and a support component 8 for limiting support of the ceramic vacuum tube are arranged inside the positioning gap 6.

[0022] Among them, the material guiding mechanism 5 includes a material guiding baffle 9 arranged on the inner wall of the supporting mounting plate 3 via a rotating shaft, and the inner wall of the supporting mounting plate 3 is connected to the material guiding baffle 9 via a rotating shaft, and the electric push rod 10 connected to the material guiding baffle 9 via the rotating shaft. When the feed conveyor belt 4 transports the ceramic vacuum tube, the electric push rod 10 can be started according to the model of the ceramic vacuum tube, and the output shaft of the electric push rod 10 drives the material guiding baffle 9 to move via the rotating shaft, so that the distance between the two material guiding baffles 9 can be adjusted to adapt to the use of ceramic vacuum tubes of different specifications.

[0023] Among them, the positioning assembly 7 includes two first hydraulic cylinders 11 which are respectively arranged on the inner walls of the two supporting mounting plates 3 and horizontally distributed inside the positioning gap 6. The output shaft of the first hydraulic cylinder 11 is provided with an arc-shaped positioning plate 12. The output shaft of the first hydraulic cylinder 11 pushes the positioning plate 12 to move, so that the two positioning plates 12 cooperate with each other to clamp and fix the ceramic vacuum tube.

[0024] Among them, the support assembly 8 includes a support top plate 13 which is arranged on the coating machine 1 via a rotating shaft and is located at the positioning gap 6, and a servo motor 14 is installed on the coating machine 1 to drive the support top plate 13 to rotate. After the output shaft of the electric push rod 10 drives the two material guide baffles 9 to separate from each other, the output shaft of the servo motor 14 drives the support top plate 13 to rotate downward, so that the support top plate 13 rotates a certain angle, and the maximum rotation angle is 60 degrees, so that the coated ceramic vacuum tube can be discharged.

[0025] The bottom ends of the coating machine 1 and the supporting mounting plate 3 are provided with a discharge conveyor belt 15 located at the positioning gap 6. After the supporting top plate 13 rotates, the ceramic vacuum tube rolled down will fall onto the discharge conveyor belt 15, thereby discharging the ceramic vacuum tube.

[0027] Embodiment 2, as Figure 1 As shown, the technical feature different from Example 1 is that the coating machine 1 is provided with an adjusting component 16 for adjusting the position of the coating unit 2, and the adjusting component 16 includes a second hydraulic cylinder 17 installed on the coating machine 1, and the output shaft of the second hydraulic cylinder 17 is connected to one end of the coating unit 2, and a dovetail block is provided at the bottom end of the coating unit 2, and a dovetail groove 18 matching the dovetail block is provided on the coating machine 1. When coating is required, the output shaft of the second hydraulic cylinder 17 pushes the coating unit 2 to move, and at the same time the dovetail block moves inside the dovetail groove 18, thereby improving the stability of the movement of the coating unit 2.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
