Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency device testing, and in particular to a universal radio frequency device testing fixture. Background Art

[0002] RF components are the core of the front-end of wireless communication systems, including filters, duplexers, couplers, switches, antennas, etc. During testing, RF components are connected to test instruments through test fixtures, from which relevant parameter indicators are read.

[0003] During the use of RF devices, multiple RF connectors may be connected in multiple directions. RF connectors are made of copper, which can effectively reduce RF losses during transmission. At the same time, there are multiple connectors of the RF connector. During the clamping test of the RF device, when clamping at both ends or clamping in other directions, due to the presence of the RF connector, clamping is relatively inconvenient. Directly clamping with a clamping plate can easily affect the connection of the RF connector. Therefore, a universal RF device test fixture is proposed to solve the above problems. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a universal radio frequency device testing fixture, including a placement plate, an inner wall of the placement plate is fixedly connected to a detection needle, an outer surface of the placement plate is fixedly connected to an opening and closing mechanism, and a bottom of the placement plate is fixedly connected to a cooling mechanism; the placement plate provides support for the radio frequency device, the detection needle can test the joints around the radio frequency device, and the opening and closing mechanism can open the upper space of the placement plate when in use, so as to facilitate the placement of the radio frequency device on the surface of the placement plate. When the radio frequency device is placed, the opening and closing mechanism is closed to protect the radio frequency device. The surface-mount radio frequency device needs to be powered on and tested before operation, that is, the surface-mount radio frequency device needs to be powered on and operated. At this time, the product itself will generate a large amount of heat, and the radio frequency device is sealed and protected by the opening and closing mechanism, which may cause the temperature inside the box to be too high. The high temperature generated by the power-on operation cannot be quickly dissipated, resulting in the experimental environment temperature exceeding the standard set environment temperature, causing the product to overheat and produce adverse reactions, and causing problems with the placement plate being heated, thereby affecting subsequent tests. Therefore, the bottom of the placement plate is cooled by the cooling mechanism.

[0005] The opening and closing mechanism includes an opening and closing cover, the bottom of which is fixedly connected to a sponge block, a spring belt fixedly connected to the side of the opening and closing cover close to the sponge block, an inclined plate fixedly connected to the outer surface of the opening and closing cover, the inner wall of the inclined plate rotatably connected to a rotating shaft, the outer surface of the rotating shaft is provided with a semicircular groove, and the outer surface of the rotating shaft is rotatably connected to a picking component. When the opening and closing cover is closed, the sponge block presses against the upper surface of the RF device, compacting it. Since the sponge block is made of a soft material, it will not damage its surface. At the same time, the spring belt has the same function as the spring, and both have elasticity and reset functions. The opening and closing cover can contact or separate from the upper surface of the placement plate under the rotation of the rotating shaft, thereby wrapping the internal RF device.

[0006] Furthermore, the side of the spring belt away from the closing cover is fixedly connected to the upper surface of the cooling mechanism, and the outer surface of the rotating shaft is fixedly connected to the inner wall of the cooling mechanism.

[0007] Furthermore, the picking component includes a connecting plate, the bottom of which is fixedly connected to a rubber rod, the side of the connecting plate near the rotating shaft being fixedly connected to a rotating plate, a connecting rope being provided above the rotating plate, the end of the connecting rope away from the connecting plate being fixedly connected to a connecting shaft, and pulleys being fixedly connected to both ends of the connecting shaft. The rubber rod provides elasticity and resets the rotating plate, allowing the rotating plate to rotate within the semicircular groove. The notch of the semicircular groove acts as a limiter for the rotating plate, preventing the connecting plate from rotating around the outer surface of the rotating shaft toward the side near the pull rope due to the elasticity of the rubber rod.

[0008] Furthermore, a semicircular magnet is fixedly connected to the outer surface of the connecting shaft. A circular plate is slidably connected to each side of the semicircular magnet. A long magnetic strip is fixedly connected to the inner wall of the circular plate. The bottom of the circular plate is provided with a protrusion and a support groove. The semicircular magnet can slide along the protrusion on the bottom of the circular plate, repelling the long magnetic strip and pushing the long magnetic strip and the circular plate upward. The support groove facilitates the inner wall of the placement plate to provide support for the circular plate, preventing it from sliding down.

[0009] Furthermore, one end of the rubber rod away from the connecting plate is fixedly connected to the outer surface of the cooling mechanism, the inner wall of the rotating plate is rotatably connected to the inner wall of the semicircular groove, the end of the connecting rope away from the connecting shaft is fixedly connected to the side of the connecting plate close to the rotating plate, the outer surface of the circular plate is slidably connected to the inner wall of the placement plate, and the two sides of the semicircular magnetic block are slidably connected to the outer surface of the protrusion.

[0010] Furthermore, the cooling mechanism includes a cooling box, with plugs fixedly connected to both sides of the cooling box, a convex plate fixedly connected to the inner wall of the cooling box, a support plate fixedly connected to the inner wall of the cooling box, a trigger component fixedly connected to the upper surface of the support plate, and a spoiler component disposed below the trigger component. Moisture can be placed inside the cooling box to facilitate cooling the bottom of the plate. The plugs are provided to facilitate opening the two sides of the cooling box to replace new water. The convex plates can trigger the operation of the spoiler component to disturb the water inside the cooling box.

[0011] Furthermore, the triggering component includes a bent shaft, the outer surface of which is slidably connected to a fixed box, the inner wall of which is fixedly connected to a pressure sensor, and the side of the pressure sensor closest to the bent shaft is fixedly connected to an extrusion belt. The bent shaft slides left and right along the inner wall of the fixed box under the sliding motion of the pulley, squeezing the extrusion belt, causing the pressure sensor to sense the change in pressure, thereby controlling the operation of the spoiler.

[0012] Furthermore, the spoiler component includes a spoiler blade, the outer surface of the spoiler blade is fixedly connected to a spoiler shaft, the inner surface of the spoiler shaft is rotatably connected to a spoiler frame, the center of the spoiler frame is fixedly connected to a rotating shaft, and the bottom end of the rotating shaft is fixedly connected to the output end of the motor. The spoiler blade can rotate along the inner wall of the cooling box to disturb the moisture inside it, so that the moisture inside the cooling box can flow fully. At the same time, during the rotation process, the spoiler blade will contact the convex plate, and the rotation of the spoiler blade by the convex plate touching the spoiler blade will drive the rotation of the spoiler blade and the spoiler shaft. Through the rotation of the spoiler blade, the moisture at the bottom of the cooling box is brought to the upper part, so that the moisture on the upper and lower sides can be fully merged together, avoiding the upper moisture being heated and the lower moisture being overcooled, resulting in the problem that the moisture inside the cooling box has a poor cooling effect on the RF device placed on the upper part of the board.

[0013] Furthermore, the cooling box is fixedly connected to the bottom end of the rubber rod on one side close to the connecting plate, the upper surface of the cooling box is fixedly connected to the bottom end of the spring belt, the upper surface of the cooling box is fixedly connected to the lower surface of the placement plate, the end of the bending axis away from the pressure gauge is fixedly connected to the outer surface of the pulley, the end of the extrusion belt away from the pressure gauge is fixedly connected to the side of the bending axis away from the pulley, the bottom of the fixed box is fixedly connected to the upper surface of the support plate, and the bottom of the motor is fixedly connected to the bottom of the inner wall of the cooling box.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. This device clamps the upper surface of the RF device on the placement plate by rotating the opening and closing cover and sponge block inside the opening and closing mechanism, thereby avoiding contact with the RF connectors around the RF device, thereby not affecting the normal detection of the RF device. At the same time, the closure of the opening and closing cover can protect the RF device during the detection process, preventing outsiders or objects from accidentally touching it, causing the RF device to move and thus affecting the detection work.

[0016] 2. After the RF device is tested, the opening and closing cover is rotated clockwise around the rotating shaft to facilitate the removal of the RF device. During this process, the rotation of the opening and closing cover is used to push the rotation of the connecting plate and the rotating plate, so that the pull rope can pull the semicircular magnetic block and the pulley to slide until the semicircular magnetic block moves to the bottom of the long magnetic block, and then push the long magnetic block and the circular plate upward, pushing the RF device upward, leaving a certain gap between the RF device and the upper surface of the placement plate, which is convenient for the staff to pick up, and there will be no problem of inconvenience for the staff to pick up due to the small gap between the bottom of the RF device and the upper surface of the placement plate.

[0017] 3. A semicircular groove is provided on the outer surface of the rotating shaft to limit the rotation of the rotating plate. When the semicircular magnetic block slides to the bottom of the long magnetic block, the rotating plate will be supported by the notch of the semicircular groove to prevent the staff from continuously rotating the opening and closing cover, causing the connecting plate and the rotating plate to continue to rotate around the rotating shaft, thereby causing the pull rope to pull the semicircular magnetic block away from the bottom of the long magnetic block, further preventing the circular plate and the RF device from moving upward along the inner wall of the placement plate, resulting in a small gap between the bottom of the RF device and the upper surface of the placement plate.

[0018] 4. The cooling box is located below the placement plate and is filled with water. This cools the bottom of the placement plate and the RF components, preventing excessive temperatures inside the placement plate and the lid when testing SMD RF components, which could damage the components. Furthermore, when testing multiple SMD RF components continuously, the water inside the cooling box may gradually heat up due to the heat, reducing the cooling effect on the placement plate and RF components. To refill the cooling water, open the plugs on both sides of the cooling box.

[0019] 5. When the rotating plate is stuck on the other side of the semicircular notch during rotation and no longer rotates, the connecting rope no longer pulls the connecting shaft. Therefore, the connecting shaft and the bending shaft will drive the semicircular magnetic block to slide a certain distance to the side close to the pressure gauge under the elasticity of the extrusion belt. When the pressure gauge feels the pressure back and forth, it means that a radio frequency device is placed on the surface of the placement plate, and the spoiler component needs to be controlled to assist in cooling it. Therefore, the trigger component can cool the radio frequency device in advance when it is placed, so as to avoid cooling the radio frequency device when a large amount of heat is generated, and then the cooling is not timely, resulting in damage to the radio frequency device.

[0020] 6. During operation, the trigger component can control the start-up of the spoiler component, that is, the motor drives the rotation of the spoiler shaft, the spoiler frame and the spoiler blades. During the rotation of the spoiler blades, they will touch the convex plates on the inner surface of the cooling box. The convex plates will touch the spoiler blades and the spoiler shaft to rotate around the inner surface of the spoiler frame, stirring up the water at the bottom of the cooling box, so that the hotter water above is fully mixed with the cold water below, avoiding the situation where the hotter water above cannot effectively exchange heat with the cold water below when the water is static, so that the placement plate can only contact the water with gradually rising temperature, resulting in a reduction in the cooling effect.

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0031] For example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a universal radio frequency device test fixture, comprising a placement plate 1, an inner wall of the placement plate 1 is fixedly connected to a detection needle 2, an outer surface of the placement plate 1 is fixedly connected to an opening and closing mechanism 3, and a bottom of the placement plate 1 is fixedly connected to a cooling mechanism 4; the placement plate 1 provides support for the radio frequency device, the detection needle 2 can test the connectors around the radio frequency device, and the opening and closing mechanism 3 can open the upper space of the placement plate 1 when in use, so as to facilitate the placement of the radio frequency device on the surface of the placement plate 1. When the radio frequency device is placed, the opening and closing mechanism 3 is closed to protect the radio frequency device. The surface-mount radio frequency device needs to be powered on and tested before operation, that is, the surface-mount radio frequency device needs to be powered on and operated. At this time, the product itself generates a large amount of heat, and the radio frequency device is sealed and protected by the opening and closing mechanism 3, which may cause the temperature inside the box to be too high. The high temperature generated by the power-on operation cannot be quickly dissipated, causing the experimental environment temperature to exceed the standard set environment temperature, causing the product to overheat and cause adverse reactions, and causing problems with the placement plate 1 due to heating, thereby affecting subsequent tests. Therefore, the cooling mechanism 4 is used to cool the bottom of the placement plate 1.

[0032] First, when it is necessary to test the RF device, the opening and closing mechanism 3 is opened, and the RF device is placed on the upper surface of the placement plate 1. The pins around the RF device are detected by the detection needle 2, and then the upper surface of the RF device is pressed by the opening and closing mechanism 3. At the same time, the opening and closing mechanism 3 protects the RF device to prevent outsiders or objects from touching it, causing the RF device to move and affect the test. Finally, when testing the surface-mount RF device, the placement plate 1 and the RF device and other components on the placement plate 1 are cooled by the cooling mechanism 4.

[0033] The opening and closing mechanism 3 includes an opening and closing cover 31, a sponge block 32 is fixedly connected to the bottom of the opening and closing cover 31, a spring belt 33 is fixedly connected to the side of the opening and closing cover 31 close to the sponge block 32, an inclined plate 34 is fixedly connected to the outer surface of the opening and closing cover 31, a rotating shaft 35 is rotatably connected to the inner wall of the inclined plate 34, a semicircular groove 36 is provided on the outer surface of the rotating shaft 35, and a picking component 37 is rotatably connected to the outer surface of the rotating shaft 35. When the opening and closing cover 31 is closed, the sponge block 32 will press on the upper surface of the radio frequency device to compress it. Since the sponge block 32 is made of soft material, it will not cause damage to its surface. At the same time, the spring belt 33 has the same function as the spring, and both have elasticity and reset functions. The opening and closing cover 31 can contact or separate from the upper surface of the placement plate 1 under the rotation of the rotating shaft 35, thereby wrapping the radio frequency device inside.

[0034] The side of the spring band 33 away from the closing cover 31 is fixedly connected to the upper surface of the cooling mechanism 4 , and the outer surface of the rotating shaft 35 is fixedly connected to the inner wall of the cooling mechanism 4 .

[0035] The opening and closing cover 31 is opened clockwise around the outer surface of the rotating shaft 35 to expose the upper surface of the placement plate 1, and then the RF device is placed on the upper surface of the placement plate 1 so that the pin connector of the RF device is aligned with the detection needle 2. At this time, the RF device is detected by the detection needle 2. When the RF device is placed, the opening and closing cover 31 is slowly loosened, and the opening and closing cover 31 is reset under the elasticity of the spring belt 33, that is, the opening and closing cover 31 drives the inclined plate 34 to rotate counterclockwise around the rotating shaft 35 until the sponge block 32 is pressed against the upper surface of the RF device, pressing the RF device tightly, avoiding contact with the connectors around the RF device, resulting in inconvenient clamping testing.

[0036] During the test of the RF device, the opening and closing cover 31 is covered on top of the RF device, protecting the surrounding of the RF device, and preventing foreign objects from contacting the RF device, causing the RF device to move, thereby affecting the test results.

[0037] The retrieval member 37 includes a connecting plate 371, with a rubber rod 372 fixedly connected to the bottom of the connecting plate 371. A rotating plate 373 is fixedly connected to the side of the connecting plate 371 near the rotating shaft 35. A connecting rope 374 is provided above the rotating plate 373. The end of the connecting rope 374 away from the connecting plate 371 is fixedly connected to a connecting shaft 375. Both ends of the connecting shaft 375 are fixedly connected to pulleys 376. The rubber rod 372 provides elasticity and reset, allowing the rotating plate 373 to rotate within the semicircular groove 36. The notch of the semicircular groove 36 acts as a limiter for the rotating plate 373, preventing the connecting plate 371 from rotating around the outer surface of the rotating shaft 35 toward the side near the pull rope due to the elasticity of the rubber rod 372.

[0038] A semicircular magnet 377 is fixedly connected to the outer surface of the connecting shaft 375. A circular plate 378 is slidably connected to both sides of the semicircular magnet 377. A long magnetic strip 379 is fixedly connected to the inner wall of the circular plate 378. A protrusion 340 is provided at the bottom of the circular plate 378, and a support groove 341 is provided at the bottom of the circular plate 378. The semicircular magnet 377 can slide along the protrusion 340 at the bottom of the circular plate 378, and repel the long magnetic strip 379. Both are strong magnets. The semicircular magnet 377 can push the long magnetic strip 379 and the circular plate 378 upward. The function of the support groove 341 is to facilitate the inner wall of the placement plate 1 to provide support for the circular plate 378, preventing it from sliding down.

[0039] One end of the rubber rod 372 away from the connecting plate 371 is fixedly connected to the outer surface of the cooling mechanism 4, the inner wall of the rotating plate 373 is rotatably connected to the inner wall of the semicircular groove 36, the end of the connecting rope 374 away from the connecting shaft 375 is fixedly connected to the side of the connecting plate 371 close to the rotating plate 373, the outer surface of the circular plate 378 is slidably connected to the inner wall of the placement plate 1, and the two sides of the semicircular magnetic block 377 are slidably connected to the outer surface of the protrusion 340.

[0040] After the RF device test is completed, since the RF device is placed on the surface of the placement plate 1, the opening and closing cover 31, the sponge block 32, and the inclined plate 34 are rotated clockwise around the outer surface of the rotating shaft 35 to expose the RF device below. Since the gap between the bottom of the RF device and the upper surface of the placement plate 1 is very small, it is more troublesome to take it out. Therefore, when the opening and closing cover 31 is rotated clockwise around the outer surface of the rotating shaft 35 to a certain extent, the side of the inclined plate 34 away from the closing cover 31 will abut against the upper surface of the connecting plate 371 and continue to push the connecting plate 371 and the rotating plate 373 to rotate clockwise around the outer surface of the rotating shaft 35. The rotating plate 373 will squeeze the top of the rubber rod 372 during the clockwise rotation. At the same time, the rotating plate 373 will pull the pull rope to move during the rotation, and the connecting rope 374 will pull the pulley 376 along the upper surface of the cooling mechanism 4. When the cam 373 is in the process of being rotated, the cam 373 and the connecting plate 371 are prevented from rotating. At this time, the connecting rope 374 will also pull the pulley 376 and the semicircular magnetic block 377 to slide toward the side close to the long magnetic block 379 until the semicircular magnetic block 377 moves to the bottom of the long magnetic block 379, repelling each other with the long magnetic block 379 and pushing the long magnetic block 379 and the circular plate 378 to move upward. The circular plate 378 can slide upward along the inner wall of the placement plate 1 and push the RF device on the surface of the placement plate 1 upward, so that there is enough gap between the bottom of the RF device and the upper surface of the placement plate 1, which is convenient for the staff to take the RF device out from the surface of the placement plate 1. During the sliding of the semicircular magnetic block 377 , the semicircular magnetic block 377 will slide along the protrusion 340 at the bottom of the circular plate 378 , and the sliding of the semicircular magnetic block 377 and the pulley 376 will be limited by the protrusions 340 on both sides.

[0041] When the RF device is taken away by the staff, the opening and closing cover 31 is loosened, and the opening and closing cover 31 is reset under the elasticity of the spring belt 33. At the same time, the inclined plate 34 will no longer squeeze the connecting plate 371 during the clockwise rotation. Therefore, the connecting plate 371 drives the rotating plate 373 to reset and rotate under the elasticity of the rubber rod 372 until the rotating plate 373 is stuck on the other side of the semicircular groove 36 during rotation, causing the rotating plate 373 to be stuck and unable to continue rotating.

[0042] For example 2, please refer to Figures 1-8The present invention provides a technical solution: Based on the first embodiment, a cooling mechanism 4 includes a cooling box 41, with plugs 42 fixedly connected to both sides of the cooling box 41, a protruding plate 43 fixedly connected to the inner wall of the cooling box 41, a support plate 44 fixedly connected to the inner wall of the cooling box 41, a trigger component 45 fixedly connected to the upper surface of the support plate 44, and a spoiler component 46 disposed below the trigger component 45. Moisture can be placed inside the cooling box 41 to facilitate cooling the bottom of the placement plate 1. The purpose of providing the plugs 42 is to facilitate opening the two sides of the cooling box 41 to replace new water. The protruding plate 43 can trigger the operation of the spoiler component 46 to disturb the water inside the cooling box 41.

[0043] When detecting a surface-mount RF device, it needs to be powered on, so the product itself will generate a lot of heat. The RF device is protected by the opening and closing cover 31 during the test. In order to avoid the temperature of the space surrounded by the placement plate 1 and the opening and closing cover 31 being too high, which may cause damage to the RF device, the placement plate 1 and the internal space need to be properly cooled.

[0044] The interior of the cooling box 41 is replenished with a certain amount of water, which can cool the bottom of the placement plate 1 to a certain extent. When multiple surface-mount RF devices are tested continuously, the water inside the cooling box 41 may gradually be affected by the heat and heat up, reducing the cooling effect on the placement plate 1 and the RF device. Therefore, the water inside the cooling box 41 needs to be replaced with cold water, and the water can be drained and supplied through the plugs 42 on both sides of the cooling box 41.

[0045] The trigger component 45 includes a curved shaft 451, the outer surface of which is slidably connected to a fixed box 452. A pressure sensor 453 is fixedly connected to the inner wall of the fixed box 452. A compression belt 454 is fixedly connected to the side of the pressure sensor 453 closest to the curved shaft 451. The curved shaft 451 slides left and right along the inner wall of the fixed box 452 under the sliding movement of the pulley 376, squeezing the compression belt 454, causing the pressure sensor 453 to sense the pressure change, thereby controlling the operation of the spoiler 46.

[0046] As can be seen from the above, when the rotating plate 373 is stuck on the other side of the semicircular groove 36 during rotation and no longer rotates, the connecting rope 374 no longer pulls the connecting shaft 375. Therefore, the connecting shaft 375 and the bending shaft 451 will drive the semicircular magnetic block 377 to slide a certain distance to the side close to the pressure gauge 453 under the elasticity of the extrusion belt 454. When the pressure gauge 453 feels the pressure back and forth, it indicates that a radio frequency device is placed on the surface of the placement plate 1, and it is necessary to control the spoiler component 46 to perform auxiliary cooling treatment on it. Therefore, the trigger component 45 can cool the radio frequency device in advance when it is placed.

[0047] The spoiler component 46 includes a spoiler blade 461, the outer surface of the spoiler blade 461 is fixedly connected to the spoiler shaft 462, the inner surface of the spoiler shaft 462 is rotatably connected to the spoiler frame 463, the center of the spoiler frame 463 is fixedly connected to the rotating shaft 464, and the bottom end of the rotating shaft 464 is fixedly connected to the output end of the motor 465. The spoiler blade 461 can rotate along the inner wall of the cooling box 41 to disturb the moisture inside it, so that the moisture inside the cooling box 41 can flow fully. At the same time, the spoiler blade 461 will contact the convex plate 43 during the rotation, and the convex plate 43 will touch the rotation of the spoiler blade 461, thereby driving the rotation of the spoiler blade 461 and the spoiler shaft 462. Through the rotation of the spoiler blade 461, the moisture at the bottom of the cooling box 41 is brought to the upper part, so that the moisture on the upper and lower sides can be fully integrated together, avoiding the upper moisture from being heated and the lower moisture from being overcooled, resulting in the moisture inside the cooling box 41 having a poor cooling effect on the RF device on the upper part of the placement plate 1.

[0048] The side of the cooling box 41 close to the connecting plate 371 is fixedly connected to the bottom end of the rubber rod 372, the upper surface of the cooling box 41 is fixedly connected to the bottom end of the spring belt 33, the upper surface of the cooling box 41 is fixedly connected to the lower surface of the placement plate 1, the end of the bending axis 451 away from the pressure gauge 453 is fixedly connected to the outer surface of the pulley 376, the end of the extrusion belt 454 away from the pressure gauge 453 is fixedly connected to the side of the bending axis 451 away from the pulley 376, the bottom of the fixed box 452 is fixedly connected to the upper surface of the support plate 44, and the bottom of the motor 465 is fixedly connected to the bottom of the inner wall of the cooling box 41.

[0049] When the trigger component 45 is in operation, the operation of the spoiler component 46 can be controlled, that is, the motor 465 starts and drives the spoiler shaft 462, the spoiler frame 463 and the spoiler blade 461 to rotate. During the rotation of the spoiler blade 461, it will touch the convex plate 43 on the inner surface of the cooling box 41. The convex plate 43 will touch the spoiler blade 461 and the spoiler shaft 462 to rotate around the inner surface of the spoiler frame 463, stirring up the water at the bottom of the cooling box 41, so that the hotter water above is fully mixed with the cold water below, avoiding the problem that the hotter water above cannot effectively exchange heat with the cold water below when the water is static, resulting in the placement plate 1 only slowly contacting the water with gradually rising temperature, resulting in a reduction in the cooling effect.

[0050] The specific working process of the present invention is as follows:

[0051] First, by rotating the opening and closing cover 31 and the sponge block 32 inside the opening and closing mechanism 3, the upper surface of the RF device on the surface of the placement plate 1 is clamped, which can avoid contact with the RF connectors around the RF device, thereby not affecting the normal detection of the RF device. At the same time, the closure of the opening and closing cover 31 can protect the RF device during the detection process, avoiding accidental touch by outsiders or external objects, causing the RF device to move and thus affecting the detection work.

[0052] After the RF device test is completed, the opening and closing cover 31 is rotated clockwise around the rotating shaft 35 to facilitate the removal of the RF device. In this process, the rotation of the opening and closing cover 31 is used to promote the rotation of the connecting plate 371 and the rotating plate 373, so that the pull rope can pull the semicircular magnetic block 377 and the pulley 376 to slide until the semicircular magnetic block 377 moves to the bottom of the long magnetic block 379, and then pushes the long magnetic block 379 and the circular plate 378 upward, pushing the RF device upward, so that there is a certain gap between the RF device and the upper surface of the placement plate 1, which is convenient for the staff to take it, and there will be no problem of inconvenience for the staff to take it because the gap between the bottom of the RF device and the upper surface of the placement plate 1 is too small.

[0053] A semicircular groove 36 is provided on the outer surface of the rotating shaft 35, which can limit the rotation of the rotating plate 373. When the semicircular magnetic block 377 slides to the bottom of the long magnetic block 379, the rotating plate 373 will be supported by the notch of the semicircular groove 36, preventing the staff from continuously rotating the opening and closing cover 31, causing the connecting plate 371 and the rotating plate 373 to continue to rotate around the rotating shaft 35, thereby causing the pull rope to pull the semicircular magnetic block 377 to slide away from the bottom of the long magnetic block 379, further making it impossible for the circular plate 378 and the radio frequency device to move upward along the inner wall of the placement plate 1, so that there is always a small gap between the bottom of the radio frequency device and the upper surface of the placement plate 1.

[0054] Cooling box 41 is located below placement plate 1 and is filled with water. This cools the bottom of placement plate 1 and the RF components, preventing excessive temperatures within placement plate 1 and lid 31 during testing of SMD RF components, which could damage the components. Furthermore, when testing multiple SMD RF components continuously, the water inside cooling box 41 may gradually heat up due to the heat, reducing the cooling effect on placement plate 1 and the RF components. This can be replaced with fresh cooling water by opening plugs 42 on both sides of cooling box 41.

[0055] When the rotating plate 373 is stuck on the other side of the semicircular groove 36 during rotation and no longer rotates, the connecting rope 374 no longer pulls the connecting shaft 375. Therefore, the connecting shaft 375 and the bending shaft 451 will drive the semicircular magnetic block 377 to slide a certain distance to the side close to the pressure gauge 453 under the elasticity of the extrusion belt 454. When the pressure gauge 453 feels the pressure back and forth, it means that a radio frequency device is placed on the surface of the placement plate 1, and it is necessary to control the spoiler component 46 to assist in cooling it. Therefore, the trigger component 45 can cool the radio frequency device in advance when it is placed, so as to avoid cooling the radio frequency device when a large amount of heat is generated, and then the cooling is not timely, resulting in damage to the radio frequency device.

[0056] During operation, the trigger component 45 can control the operation of the spoiler component 46, that is, the motor 465 starts and drives the spoiler shaft 462, the spoiler frame 463 and the spoiler blade 461 to rotate. During the rotation of the spoiler blade 461, it will touch the convex plate 43 on the inner surface of the cooling box 41. The convex plate 43 will touch the spoiler blade 461 and the spoiler shaft 462 to rotate around the inner surface of the spoiler frame 463, stirring up the water at the bottom of the cooling box 41, so that the hotter water above is fully mixed with the cold water below, avoiding the situation where the hotter water above cannot effectively exchange heat with the cold water below when the water is static, so that the placement plate 1 can only contact the water with gradually rising temperature, resulting in a reduction in the cooling effect.
