[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a radio frequency power supply test device, including a test system body 1; also including a temperature control box 2, the test system body 1 is located inside the temperature control box 2; a conveyor belt 3, the conveyor belt 3 is connected to the temperature control box 2, and the conveyor belt 3 transports the placed radio frequency power supply; a heat insulation curtain 4, the heat insulation curtain 4 is located at the openings on both sides of the temperature control box 2; a positioning mechanism 5, the positioning mechanism 5 is located inside the temperature control box 2, the positioning mechanism 5 fixes the radio frequency power supply at a predetermined position and adjusts the placement angle of the radio frequency power supply; a docking mechanism 6, the docking mechanism 6 is connected to the positioning mechanism 5, after the positioning mechanism 5 adjusts the position of the radio frequency power supply, the docking mechanism 6 docks the connector of the test system body 1 with the connector of the radio frequency power supply, and after the connectors are docked, the rotational joints at different radio frequency power supply connectors are kept twisted to the same extent.

[0033] When in use, the placed RF power supply is automatically moved into the temperature control box 2 through the provided conveyor belt 3, and the RF power supply is fixed at a specified position and its placement angle is adjusted through the positioning mechanism 5 to prevent the RF from tilting due to squeezing when passing through the thermal insulation curtain 4. The connector of the test system body 1 is docked with the connector of the RF power supply through the provided docking mechanism 6, and the rotational joints at different RF power supply connectors are twisted to the same amplitude after the connectors are docked, thereby ensuring that the connection between the connector of the test system body 1 and the connector of the RF power supply remains consistent during each test, which helps to ensure the accuracy and repeatability of the test results, avoids the need for staff to manually adjust the number of rotations of the rotational joint each time a test is conducted, simplifies the test process and improves the test efficiency. After the connector of the test system is docked with the connector of the RF power supply, the temperature control box 2 adjusts the internal temperature, and the temperature in the temperature control box 2 is isolated from the outside world through the thermal insulation curtain 4 to cooperate in controlling the working conditions of the RF power supply at different temperatures. The spectrum analyzer and power meter in the test equipment body measure the output characteristics of the RF power supply at different temperatures.

[0034] The positioning mechanism 5 includes a movable plate 50 located on both sides of the conveyor belt 3. The movable plate 50 is fixedly connected to a plurality of positioning columns 51 on the side close to the conveyor belt 3. The movable plate 50 is fixedly connected to a cylinder 52 on the end away from the positioning columns 51. The cylinder 52 is fixedly connected to the inner wall of the temperature control box 2. A distance sensor 53 is installed inside the temperature control box 2. The distance sensor 53 is located on one side of the movable plate 50. The distance sensor 53 is respectively connected to the cylinder 52 and the conveyor belt 3.

[0035] The staff places the RF power supply on the production line so that the side of the RF power supply with the connector faces the docking mechanism 6. The transmission mechanism of the production line sends the RF power supply into the temperature control box 2. The conveyor belt 3 in the temperature control box 2 continues to drive the RF power supply to move into the temperature control box 2. When the end of the RF power supply moves to the detection position of the distance sensor 53, the RF power supply blocks the distance sensor 53. After the distance sensor 53 is triggered, it transmits a signal to the conveyor belt 3, and the conveyor belt 3 stops rotating, so that the conveyor belt 3 no longer drives the RF power supply to move. After the conveyor belt 3 stops working, the cylinders 52 on both sides are started at the same time, and the cylinders 52 push the moving plate 50 to approach the RF power supply. The positioning columns 51 of the moving plate 50 are made of rubber and protrude from the surface of the moving plate 50. Therefore, when the moving plate 50 approaches the RF power supply, the positioning columns 51 on both sides of the RF power supply will first contact the RF power supply casing, and the RF power supply is fixed at the position where the distance sensor 53 is triggered by a plurality of symmetrically arranged positioning columns 51.

[0036] A monitoring component 7 for testing the heat dissipation effect of the RF power supply under high temperature conditions is provided inside the temperature control box 2. The monitoring component 7 includes a piston plate 70 located inside the movable plate 50. An air pressure chamber 71 is provided on the inner wall of the movable plate 50. The piston plate 70 is slidably connected to the inner wall of the air pressure chamber 71. A connecting frame 72 is fixedly connected to one end of the piston plate 70. A return spring 77 is provided on the outer side of the connecting frame 72. One end of the return spring 77 is fixedly connected to the piston plate 70, and the other end of the return spring 77 is fixedly connected to the inner wall of the air pressure chamber 71. A temperature sensor 73 is installed on the side of the connecting frame 72 close to the conveyor belt 3. Two temperature sensors 73 are provided, one temperature sensor 73 is recessed inside the connecting frame 72, and the other temperature sensor 73 protrudes from the surface of the connecting frame 72. An air inlet pipe 74 is connected to the outer side of the air pressure chamber 71. An air pump 75 is fixedly connected to the end of the air inlet pipe 74 away from the movable plate 50. An alarm light 76 is installed on the outer side of the temperature control box 2, and the alarm light 76 is connected to the temperature sensor 73.

[0037] When the connector of the test system body 1 is connected to the connector of the RF power supply, the air pump 75 supplies air to the air inlet pipe 74, and the air inlet pipe 74 flows the air into the air pressure chamber 71, so that the air pressure in the air pressure chamber 71 increases and pushes the piston plate 70 to slide on the inner wall of the air pressure chamber 71, and the piston plate 70 drives the connecting frame 72 to move. While squeezing the reset spring 77, the connecting frame 72 drives the temperature sensor 73 recessed inside the connecting frame 72 close to the heat dissipation port of the RF power supply, and the temperature sensor 73 protruding from the surface of the connecting frame 72 contacts the RF power supply shell.

[0038] After the docking is completed, the temperature in the temperature control box 2 gradually increases to cooperate with the measurement of the output characteristics of the RF power supply in a high temperature environment. As the temperature rises, the heat dissipation mechanism in the RF power supply continues to work when the RF power supply works normally, and discharges the heat through the heat dissipation port of the RF power supply. The temperature sensor 73 recessed in the connecting frame 72 detects the gas discharged from the heat dissipation port of the RF power supply, and the temperature sensor 73 protruding from the surface of the connecting frame 72 monitors the temperature of the RF power supply shell. The heat dissipation effect of the RF power supply is tested by the fluctuations detected by the two temperature sensors 73. If under high temperature conditions, the temperature change of the exhaust air flow detected by the temperature sensor 73 recessed in the connecting frame 72 is small, while the temperature sensor 73 protruding from the surface of the connecting frame 72 measures that the temperature change rate of the RF power supply shell is fast, and the length of time that the RF power supply works at full load at this temperature is compared. If the length of time is lower than the standard value, it means that the heat dissipation system in the RF power supply is faulty, and the alarm light 76 alarms to cooperate with the staff to deal with the RF power supply with heat dissipation failure.

[0039] The docking mechanism 6 includes a connecting hole 60 opened on the surface of the movable plate 50, the joint of the test system main body 1 is located inside the connecting hole 60, a fixed block 61 is fixedly connected between the connecting hole 60 and the joint of the test system main body 1, a connecting piece 62 is provided at one end of the connecting hole 60 close to the conveyor belt 3, and a rotating piece 63 is provided between the multiple connecting pieces 62 to drive the multiple connecting pieces 62 to rotate in the same direction and the same angle.

[0040] When the docking mechanism 6 is working, the movable plate 50 drives the fixed block 61 to move, and the fixed block 61 drives the connector of the test system body 1 to be vertically close to the connector of the RF power supply. When the cylinder 52 drives the movable plate 50 to move, the connecting piece 62 is sleeved on the outside of the rotating joint of the RF power supply. As the connecting frame 72 moves, the connecting frame 72 drives the rotating piece 63 to work, and the rotating piece 63 drives multiple connecting pieces 62 to face the same direction and rotate at the same angle, so as to maintain the consistency of the connection between the RF power supply and the connector of the test equipment body when testing different RF power supplies, avoid the need for staff to manually adjust the number of rotations of the rotating joint each time a test is performed, simplify the test process and improve the test efficiency.

[0041] The connecting member 62 includes a rotating ring 64 rotatably connected to the inner wall of the connecting hole 60, and a plurality of rubber strips 65 are fixedly connected to the inner side of the rotating ring 64. When the connecting member 62 is close to the rotating joint outside the RF power connector, the rubber strip 65 and the rotating joint are squeezed against each other, causing the rubber strip 65 to deform. The elasticity of the rubber strip 65 squeezes the rotating joint, and the plurality of rubber strips 65 clamp the rotating joint, so that when the rotating ring 64 rotates, the rubber strip 65 drives the rotating joint to rotate, thereby connecting the RF power supply to the connector of the test equipment body.

[0042] The rotating member 63 includes a gear ring 66 fixedly connected to the outer side of the rotating ring 64, the two gear rings 66 have the same number of teeth, and a toothed belt 67 is meshed on the outer side of the two gear rings 66. A transmission cylinder 68 is fixedly connected to the outer side of one of the rotating rings 64, and the transmission cylinder 68 is rotatably connected to the inner wall of the movable plate 50. A driving member 69 is provided on the outer side of the transmission cylinder 68 for driving the transmission cylinder 68 to rotate.

[0043] When the connecting frame 72 moves, it drives the driving member 69 to work, and the driving member 69 drives the transmission cylinder 68 to rotate. The transmission cylinder 68 drives the rotating ring 64 fixed thereto to rotate, and the rotating ring 64 drives the outer fixed gear ring 66 to rotate, and the gear ring 66 drives the toothed belt 67 to rotate, and the toothed belt 67 drives the remaining gear ring 66 to rotate, so that the two rotating rings 64 rotate synchronously. Since the two gear rings 66 have the same number of teeth, the two gear rings 66 rotate at the same angle under the drive of the same toothed belt 67, thereby maintaining the consistency of the connection between the RF power supply and the test equipment main body connector.

[0044] The driving member 69 includes a turbine 610 fixedly connected to the outer side of the transmission cylinder 68, a worm 611 is meshed on the outer side of the turbine 610, the worm 611 is rotatably connected to the inner wall of the movable plate 50, a transmission gear 612 is fixedly connected to the bottom end of the worm 611, a transmission rack 613 is meshed on the outer side of the transmission gear 612, the transmission rack 613 is slidably connected to the inner wall of the movable plate 50, a connecting rod 614 is fixedly connected to the outer side of the transmission rack 613, the connecting rod 614 is fixed to the connecting frame 72, and the connecting rod 614 is slidably connected to the inner wall of the movable plate 50.

[0045] When the connecting frame 72 moves, it drives the connecting rod 614 to move, the connecting rod 614 drives the transmission rack 613 to move, the transmission rack 613 drives the transmission gear 612 to rotate, the transmission gear 612 drives the worm 611 to rotate, the worm 611 drives the turbine 610 to rotate, the turbine 610 rotates to cooperate with the transmission cylinder 68 to rotate, so that the two gear rings 66 rotate at the same angle.

[0046] Embodiment 2

[0047] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the rubber strip 65 is obliquely arranged on the inner side of the rotating ring 64. The end of the rubber strip 65 close to the conveyor belt 3 is thinner than the other end, so that the rubber strip 65 has an oblique transition close to the rotating joint, which makes it convenient for the rubber strip 65 to be inserted into the outside of the rotating joint. When the rotating ring 64 rotates, the obliquely arranged rubber strip 65 can easily drive the rotating joint to rotate.
