DETAILED DESCRIPTION

[0021] Example:

[0022] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0024] A magnetron primary characteristic tester comprises a power distribution cabinet, an inspection cabinet and a test platform, wherein the power distribution cabinet and the inspection cabinet are electrically connected to the test platform respectively. The power distribution cabinet provides a test current and a test voltage for the magnetron primary characteristic test, and the primary characteristic test parameters of the magnetron are received and displayed by an instrument. The test platform comprises a waveguide detection module 1, a handling robot 2 and a pallet track module 3. The waveguide detection module 1 is used to detect the characteristic parameters of the magnetron, and a test slot 101 for placing the magnetron is provided at one end of the waveguide detection module 1. The pallet track module 3 is arranged next to the waveguide detection module 1 and is used to input and output the magnetron. The handling robot 2 is arranged above the waveguide detection module 1 and the pallet track module 3 and is used to transport the magnetron. The handling robot 2 comprises a gripper and a power sleeve 202 matching the magnetron cathode assembly. The power sleeve 202 is provided with an electrode sheet 203 for inputting the test power. The magnetron primary characteristic tester of this embodiment is suitable for the assembly line operation of magnetrons. Figure 1As shown, it is specifically arranged on one side of the magnetron assembly line 4. The magnetron to be tested sent by the magnetron assembly line 4 is sent into the detection table by the pallet track module 3. After being transported to the right place, the handling robot 2 is actuated to pick up the magnetron to be tested and transport it to the test slot 101 of the waveguide detection module 1. At the same time, the detection power is output through the electrode piece 203 inside the power sleeve 202, and the magnetron to be tested is turned on, so that the waveguide detection module 1 can detect the primary characteristic parameters of the magnetron and compare and judge whether it meets the design standards; after the detection is completed, the magnetron is returned, and the operator makes a judgment based on the detection result of the primary characteristic parameters. The qualified magnetron is normally transported to the next process, and the unqualified magnetron is reworked and adjusted.

[0025] Specifically, the tray track module 3 includes a chassis 301, a slide rail 302, a tray drive device 303, and a positioning seat 304. The positioning seat 304 is slidably mounted on the slide rail 302 via the chassis 301. The chassis 301 is connected to the tray drive device 303 and driven thereby to slide or position on the slide rail 302. The positioning seat 304 includes a central positioning hole and positioning posts 305 disposed around the positioning hole. In this embodiment, the magnetron is placed on the positioning seat 304 with the antenna assembly at the bottom and the cathode assembly at the top. The positioning hole locates the magnetron's axis through the antenna assembly, while the positioning posts 305 around the outer shell position the magnetron's outer shell, forming a precise positioning constraint for the magnetron. The placed magnetron always remains in the same position on the tray track module 3, allowing the handling robot 2 above to accurately locate and grasp it. In this embodiment, the tray drive device 303 is driven by a screw rod so that the chassis 301 and the positioning seat 304 can accurately move to the clamping position. Preferably, in this embodiment, the upper end of the positioning column 305 is provided with a chamfered section, which can play a guiding role when placing the magnetron, so that the magnetron moves toward the center of the positioning seat 304, thereby better achieving the positioning and limiting effect. As shown in the accompanying drawings, in this embodiment, a shock-absorbing gasket 306 is also provided on the upper end surface of the positioning seat 304. It can be made of a soft rubber material to avoid metal collision between the outer shell of the magnetron and the positioning seat 304 during the placement of the magnetron, so as to avoid scratches or damage.

[0026] In this embodiment, there are two groups of pallet track modules 3, which are respectively arranged on both sides of the waveguide detection module 1. When the transport robot 2 and the waveguide detection module 1 perform characteristic parameter detection on the magnetron on one side, the pallet track module 3 on the other side can transport the magnetron, reducing the idle waiting time of the transport robot 2 and the waveguide detection module 1, so as to improve the overall detection efficiency.

[0027] Similar to the above embodiment, as shown in the accompanying drawings, a number of positioning posts 305 are also provided around the test slot 101 of the waveguide detection module 1 to ensure that the transport robot 2 can accurately place the transported magnetron at a uniform detection position, thereby ensuring the accuracy of the characteristic parameter detection of each magnetron.

[0028] As shown in the accompanying drawings, in this embodiment, the handling robot 2 includes a transverse drive and a lift drive. When the magnetron is delivered to its proper location, the lift drive first activates, causing the handling robot 2 to move downward, clamp the magnetron, and then reset upward. The transverse drive then activates, transporting the magnetron to the top of the test slot 101 of the waveguide detection module 1. The lift drive then places the magnetron on the test slot 101. At this point, the magnetron's antenna end is located within the waveguide detection module 1. The electrode 203 outputs test power, causing the magnetron to generate microwaves. The waveguide detection module 1 then detects the magnetron's primary characteristic parameters, including output power, frequency, and efficiency, for comparison and analysis with design standard data to determine whether the magnetron's characteristic parameters meet the requirements. After the test is completed, the handling robot 2 and the tray track module 3 perform a reverse action, returning the magnetron to the test station. Specifically, the gripper of the handling robot 2 consists of four opening and closing L-shaped hooks 201. When the L-shaped hooks 201 are open, the width between two L-shaped hooks 201 is greater than the width of the magnetron's outer shell, allowing the handling robot 2 to move normally up and down. When the handling robot 2 is pressed down into place, the L-shaped hooks 201 close inward, inserting and clamping from the side of the magnetron's outer shell to enable transportation of the magnetron. As shown in the accompanying drawings, the opposite inner ends of the L-shaped hooks 201 are also chamfered to prevent them from being stuck on the magnetron's outer shell during the inward closing and clamping process.

[0029] As shown in the accompanying drawings, the slot body formed inwardly by the power sleeve 202 of this embodiment matches the cathode assembly of the magnetron, and specifically includes a circular segment and a clamping slot segment. The circular segment corresponds to the ceramic part of the cathode assembly, and the clamping slot segment corresponds to the cathode lead of the magnetron. That is, when the power sleeve 202 is pressed down on the cathode assembly of the magnetron, the cathode lead of the magnetron is just located in the clamping slot segment. The electrode sheet 203 is arranged in the clamping slot segment and includes two groups, which respectively clamp the positive and negative poles of the cathode lead. In this embodiment, the electrode sheet 203 is connected to the power distribution cabinet, which comprehensively controls the power output mode to detect various characteristic parameters of the magnetron. For example, as shown in the test flow chart in the accompanying drawings, when the handling robot 2 clamps the magnetron, it can control the electrode plate 203 to output a preheating power source to preheat the magnetron's filament. When the handling robot 2 transports the magnetron to the test slot 101 of the waveguide inspection module 1, it then controls the electrode plate 203 to output a high-voltage power source to begin formal characteristic parameter testing. During testing, multiple sets of test parameters can be output for repeated testing of magnetrons that fail the initial test to comprehensively determine the quality level of the magnetron under test and whether manual adjustment of the magnetron is necessary.

[0030] The above description is merely an explanation of the preferred embodiments of the present invention and should not be construed as limiting the claims. The present invention is not limited to the above embodiments, and variations in the specific structure are permitted. In short, all variations made within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
