It is the energy source for generating high-energy microwaves in vacuum tube devices and is widely used in various microwave tubes such as gyrotrons, klystrons, and traveling wave tubes. Working principle: The electron gun used in gyrotrons employs a thermionic cathode. The tungsten substrate of the cathode stores a large amount of active material. When a high voltage of tens of thousands of volts is applied between the electron gun and the high frequency, and the cathode is heated to about 1000°C, a continuous stream of high-energy electrons is generated and injected into the high-frequency system, enhancing the intensity of the microwave electromagnetic field in the device.

[0028] Please refer to Figures 1-3As shown, this utility model provides a tray mechanism for electron gun assembly and welding, which is set on the base 1 of an automated production equipment for electron gun assembly and welding. The tray mechanism includes a base 1, a tray 6 assembly, and a drive assembly. Two sliders 3 are horizontally spaced on the base 1. Each slider 3 is slidably mounted with a slide rail 4. Specifically, a reinforcing rib 11 is provided on the top of the two slide rails 4. The reinforcing rib 11 can improve the structural strength of the slide rails 4 and reduce the risk of deformation. The tray 6 assembly includes a mounting frame 5, which is fixedly mounted on the ends of the two slide rails 4. The tray 6 is detachably mounted on the mounting frame 5. The tray 6 is provided with multiple circular grooves 7, which are used to accommodate electron guns, all different cylindrical rotating parts in electron gun components, and part positioning molds. The drive assembly includes a linear drive module, which drives the mounting frame 5 and the tray 6 on it to move to the outside of the base 1.

[0029] In practical use, the tray mechanism is compatible with automated production equipment for electron gun assembly and welding. All different cylindrical rotating parts and part positioning molds within a single electron gun component are placed separately in different circular grooves 7 of the tray 6. The robotic arm can quickly and accurately locate and retrieve the required parts according to a preset program, meeting the requirements of automated production and achieving highly efficient automated assembly of electron gun welding. After the electron gun welding and assembly are completed, the assembled electron gun can be placed in the tray 6 for easy unloading, meeting the requirements of automated production and achieving highly efficient automated assembly of cylindrical rotating parts. Compared to manual assembly, which requires searching and retrieving parts from numerous tooling fixtures, this significantly shortens retrieval time and improves assembly efficiency. It avoids the use of numerous tooling fixtures in traditional manual assembly, reducing the cost of manufacturing new tooling fixtures for the development of new electron guns and lowering the production cost of the rotary tube.

[0030] The circular groove 7 is customized according to the shape and size of all the different cylindrical rotating parts and part positioning molds in the electron gun and electron gun components. It can ensure the stability of the placement of all the different cylindrical rotating parts and part positioning molds in the electron gun and electron gun components, reduce errors in the assembly process, and improve the assembly and welding accuracy.

[0031] Specifically, as a specific arrangement of the mounting frame 5, the mounting frame 5 includes a bottom mounting plate 501. The lower end face of the bottom mounting plate 501 is fixedly connected to the ends of two slide rails 4. A vertical plate 502 is mounted on the upper end face of the bottom mounting plate 501. The length direction of the vertical plate 502 is perpendicular to the movement direction of the mounting frame 5. Two mounting support plates 503 are horizontally spaced on one side end face of the vertical plate 502. The two mounting support plates 503 face outwards from the base 1 and are in the same direction as the movement direction of the mounting frame 5. A material tray 6 is detachably mounted on the top of the two mounting support plates 503.

[0032] Specifically, the upper surfaces of the two mounting support plates 503 are provided with positioning pins 9, and the lower surfaces of the tray 6 are provided with positioning holes that mate with the positioning pins 9 at their diagonal angles. This enables the tray 6 to be precisely positioned and mounted on the two mounting support plates 503. Moreover, the positioning pins 9, in conjunction with the positioning holes, can correct any deviations in the tray 6, improving its positioning accuracy. This makes automated transport of the tray 6 by the AGV feeding vehicle possible, ensuring the accuracy of the robotic arm in positioning and gripping parts, as well as the assembly accuracy.

[0033] Meanwhile, the distance between the two mounting support plates 503 is greater than the width of the AGV feeding vehicle. This arrangement facilitates the AGV feeding vehicle loading the material tray 6 onto the mounting frame 5 or unloading the material tray 6, meeting the production requirements for automated loading and unloading.

[0034] Preferably, but not limited to, a tray sensor 8 is provided on the side wall of one of the mounting support plates 503, with the sensing direction of the tray sensor 8 vertically upward. The tray sensor 8 is an ultrasonic position sensor, a radar position sensor, or a laser position sensor. The tray sensor 8 is used to identify whether the tray 6 is on the mounting bracket 5.

[0035] In this embodiment, the linear drive module is a linear electric cylinder 2, which is mounted on the upper surface of the base 1. The end of the push rod in the linear electric cylinder 2 is fixedly connected to the bottom mounting plate 501 through a connecting plate. The linear electric cylinder 2 can move the mounting frame 5 and the tray 6 on it to the outside of the base 1, and the distance between the two mounting support plates 503 is set to be greater than the width of the AGV feeding vehicle, which facilitates the AGV feeding vehicle to load or unload the tray 6 onto the mounting frame 5, thus meeting the production requirements of automated loading and unloading. After the tray 6 is loaded or unloaded, the linear electric cylinder 2 drives the mounting frame 5 and the tray 6 on it to return to the inside of the base 1, reducing the space occupied and avoiding interference or collision with other equipment.
