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 devices are the core of the front end of wireless communication systems, including filters, duplexers, couplers, switches, antennas, etc. During the test process, RF devices are connected to the test instrument through the test fixture and relevant parameter indicators are read from the test instrument.

[0003] During the use of RF devices, multiple RF connectors may be connected in multiple positions. 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 the two ends are clamped or clamped in other positions, clamping is inconvenient due to the presence of the RF connector. Direct clamping with a clamping plate is likely to 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, the inner wall of the placement plate is fixedly connected with a detection needle, the outer surface of the placement plate is fixedly connected with an opening and closing mechanism, and the bottom of the placement plate is fixedly connected with 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 for testing before working, that is, the surface-mount radio frequency device needs to be powered on for working. 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 internal temperature of the box to be too high. The high temperature generated by the power-on work cannot be quickly dissipated, resulting in the experimental environment temperature exceeding the standard set environment temperature, causing the product to overheat and have 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, a sponge block is fixedly connected to the bottom of the opening and closing cover, a spring belt is fixedly connected to the side of the opening and closing cover close to the sponge block, an inclined plate is fixedly connected to the outer surface of the opening and closing cover, the inner wall of the inclined plate is rotatably connected to a rotating shaft, a semicircular groove is provided on the outer surface of the rotating shaft, and a picking component is rotatably connected to the outer surface of the rotating shaft. When the opening and closing cover is closed, the sponge block will press on the upper surface of the radio frequency device to compress it. Since the sponge block is made of soft material, it will not cause damage to 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 to wrap the internal radio frequency device.

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

[0007] Furthermore, the taking component includes a connecting plate, a rubber rod is fixedly connected to the bottom of the connecting plate, a rotating plate is fixedly connected to the side of the connecting plate close to the rotating shaft, a connecting rope is arranged above the rotating plate, the end of the connecting rope away from the connecting plate is fixedly connected to the connecting shaft, and pulleys are fixedly connected to both ends of the connecting shaft. The rubber rod plays an elastic and resetting role, the rotating plate can rotate with the inside of the semicircular groove, and the notch of the semicircular groove plays a limiting role on the rotating plate, preventing the connecting plate from still rotating around the outer surface of the rotating shaft to the side close to the pull rope under the elasticity of the rubber rod.

[0008] Furthermore, a semicircular magnetic block is fixedly connected to the outer surface of the connecting shaft, and a circular plate is slidably connected to both sides of the semicircular magnetic block, and a long magnetic block is fixedly connected to the inner wall of the circular plate, and a protrusion is provided at the bottom of the circular plate, and a supporting groove is provided at the bottom of the circular plate. The semicircular magnetic block can slide along the protrusion at the bottom of the circular plate, and repel the long magnetic block, and can push the long magnetic block and the circular plate to move upward. The function of the supporting groove is to facilitate the inner wall of the placement plate to provide support for the circular plate, and will not cause the circular plate to slide 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, one end of the connecting rope away from the connecting shaft is fixedly connected to a 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 placing plate, and both 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, plugs are fixedly connected to both sides of the cooling box, a convex plate is fixedly connected to the inner wall of the cooling box, a support plate is fixedly connected to the inner wall of the cooling box, a trigger component is fixedly connected to the upper surface of the support plate, and a spoiler component is arranged below the trigger component. Water can be put into the cooling box to facilitate cooling the bottom of the placement plate, wherein the purpose of setting the plug is to facilitate opening the two sides of the cooling box and replacing new water, and the convex plate can trigger the operation of the spoiler component to disturb the water inside the cooling box.

[0011] Furthermore, the trigger component includes a bent shaft, the outer surface of the bent shaft is slidably connected to a fixed box, the inner wall of the fixed box is fixedly connected to a pressure gauge, and the side of the pressure gauge close to the bent shaft is fixedly connected to an extrusion belt. The bent shaft can slide left and right along the inner wall of the fixed box under the sliding of the pulley, and squeeze the extrusion belt, so that the pressure gauge can sense the change in pressure, thereby controlling the operation of the spoiler component.

[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, and at the same time, the spoiler blade will contact the convex plate during the rotation process, and the convex plate touches the rotation of the spoiler blade, thereby driving the rotation of the spoiler blade and the spoiler shaft, and the rotation of the spoiler blade brings the moisture at the bottom of the cooling box to the upper part, so that the moisture on the upper and lower sides can be fully fused 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. The device clamps the upper surface of the RF device on the placement plate surface 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, avoiding accidental touch by outsiders or objects, 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. In this process, the rotation of the opening and closing cover is used to drive the rotation of the connecting plate and the rotating plate, so that the pull rope can pull the sliding of the semicircular magnetic block and the pulley until the semicircular magnetic block moves to the bottom of the long magnetic block, thereby pushing the long magnetic block and the circular plate upward, pushing the RF device upward, and leaving a certain gap between the RF device and the upper surface of the placement plate, so that the staff can take it easily, without the 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 is too small.

[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 turning the opening and closing cover, causing the connecting plate and the rotating plate to continuously 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 set under the placement board, and its interior is filled with water, which can cool the bottom of the placement board and the RF device to avoid the problem of damage to the RF device due to the excessive temperature inside the placement board and the opening and closing cover when detecting the SMD RF device. At the same time, when testing multiple SMD RF devices continuously, the water inside the cooling box may gradually heat up due to the influence of heat, reducing the cooling effect on the placement board and the RF device. The plugs on both sides of the cooling box can be opened to replace the cooling water inside 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 it is necessary to control the spoiler component to assist in cooling it. Therefore, the trigger component can cool down 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 of the spoiler component, that is, the motor drives the spoiler shaft and the spoiler frame and the spoiler blade to rotate. During the rotation of the spoiler blade, it will touch the convex plate on the inner surface of the cooling box. The convex plate will touch the spoiler blade and the spoiler shaft to rotate around the inner surface of the spoiler frame, stirring up the moisture at the bottom of the cooling box, so that the hotter moisture at the top is fully mixed with the cold water at the bottom, avoiding the situation in which the hotter moisture at the top cannot effectively exchange heat with the cold water at the bottom when the moisture is static, so that the placement plate can only contact the moisture with gradually rising temperature, resulting in a reduction in the cooling effect.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0031] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a universal radio frequency device test fixture, comprising a placement plate 1, a detection needle 2 is fixedly connected to the inner wall of the placement plate 1, an opening and closing mechanism 3 is fixedly connected to the outer surface of the placement plate 1, and a cooling mechanism 4 is fixedly connected to the bottom of the placement plate 1; the placement plate 1 provides support for the radio frequency device, the detection needle 2 can test the joints 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, and when the radio frequency device is placed, the opening and closing mechanism 3 is closed to protect the radio frequency device, and the surface mount radio frequency device needs to be powered on for testing before working, that is, the surface mount radio frequency device needs to be powered on for working, at this time, the product itself will generate a lot of heat, and the radio frequency device is sealed and protected by the opening and closing mechanism 3, which may cause the internal temperature of the box to be too high, and the high temperature generated by the power-on work cannot be quickly dissipated, resulting in the experimental environment temperature exceeding the standard set environment temperature, causing the product to overheat and have adverse reactions, and causing problems with the placement plate 1 being heated, thereby affecting subsequent tests, so 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 then the RF device is placed on the upper surface of the placement plate 1, and 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 to wrap the radio frequency device inside.

[0034] The side of the spring belt 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 onto the upper surface of the RF device, thereby pressing the RF device tightly, avoiding contact with the connectors around the RF device, which causes the problem of inconvenient clamping test.

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

[0037] The taking component 37 includes a connecting plate 371, a rubber rod 372 is 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 close to the rotating shaft 35, a connecting rope 374 is arranged above the rotating plate 373, and a connecting shaft 375 is fixedly connected to the end of the connecting rope 374 away from the connecting plate 371, and pulleys 376 are fixedly connected to both ends of the connecting shaft 375. The rubber rod 372 plays the role of elasticity and reset, and the rotating plate 373 can rotate with the inside of the semicircular groove 36. The notch of the semicircular groove 36 plays a limiting role on the rotating plate 373, preventing the connecting plate 371 from still rotating around the outer surface of the rotating shaft 35 to the side close to the pull rope under the elasticity of the rubber rod 372.

[0038] The outer surface of the connecting shaft 375 is fixedly connected with a semicircular magnetic block 377, and both sides of the semicircular magnetic block 377 are slidably connected with a circular plate 378, and the inner wall of the circular plate 378 is fixedly connected with a long magnetic block 379, and the bottom of the circular plate 378 is provided with a protrusion 340, and the bottom of the circular plate 378 is provided with a supporting groove 341. The semicircular magnetic block 377 can slide along the protrusion 340 at the bottom of the circular plate 378, and repel the long magnetic block 379. Both are strong magnets. The semicircular magnetic block 377 can push the long magnetic block 379 and the circular plate 378 to move upward. The function of the supporting groove 341 is to facilitate the inner wall of the placement plate 1 to provide support for the circular plate 378, and will not cause the circular plate 378 to slide 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 placing 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 also 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 to move. The rotating plate 373 can rotate around the inner surface of the semicircular groove 36 during the rotation process. When the rotating plate 373 rotates clockwise to the notch of the semicircular groove 36 close to the rubber rod 372, the rotating plate 373 and the connecting plate 371 can no longer rotate due to the resistance of the notch. At this time, the connecting rope 374 will also pull the pulley 376 and the semicircular magnetic block 377 to slide to 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 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 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 Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the cooling mechanism 4 includes a cooling box 41, plugs 42 are fixedly connected to both sides of the cooling box 41, a convex plate 43 is fixedly connected to the inner wall of the cooling box 41, a support plate 44 is fixedly connected to the inner wall of the cooling box 41, a trigger component 45 is fixedly connected to the upper surface of the support plate 44, and a spoiler component 46 is arranged below the trigger component 45. Water can be put into the cooling box 41 to facilitate cooling the bottom of the placement plate 1, wherein the purpose of setting the plug 42 is to facilitate opening both sides of the cooling box 41 and replacing new water, and the convex plate 43 can trigger the operation of the spoiler component 46 to disturb the water inside the cooling box 41.

[0043] When detecting the 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 prevent the temperature of the space wrapped by the placement plate 1 and the opening and closing cover 31 from being too high, causing 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 moisture, which can cool the bottom of the placement plate 1 to a certain extent. When multiple surface-mount RF devices are tested continuously, the moisture 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 devices. Therefore, the moisture 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 bent shaft 451, a fixed box 452 is slidably connected to the outer surface of the bent shaft 451, a pressure gauge 453 is fixedly connected to the inner wall of the fixed box 452, and a pressing belt 454 is fixedly connected to the side of the pressure gauge 453 close to the bent shaft 451. The bent shaft 451 can slide left and right along the inner wall of the fixed box 452 under the sliding of the pulley 376, and press the pressing belt 454, so that the pressure gauge 453 can feel the change in pressure, thereby controlling the operation of the spoiler component 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 continues to rotate, 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 sensor 453 under the elasticity of the extrusion belt 454. When the pressure sensor 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 down 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 a spoiler shaft 462, the inner surface of the spoiler shaft 462 is rotatably connected to a spoiler frame 463, the center of the spoiler frame 463 is fixedly connected to a 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. The convex plate 43 touches 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 moisture at the bottom of the cooling box 41, so that the hotter moisture at the top is fully mixed with the cold water at the bottom, avoiding the problem that the hotter moisture at the top cannot effectively exchange heat with the cold water at the bottom when the moisture is static, resulting in the placement plate 1 can only slowly contact the moisture 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 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 drive 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 RF 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 RF device and the upper surface of the placement plate 1.

[0054] The cooling box 41 is arranged below the placement plate 1, and is filled with water, which can cool the bottom of the placement plate 1 and the RF device, so as to avoid the problem that the temperature inside the placement plate 1 and the opening and closing cover 31 is too high when the SMD RF device is detected, causing damage to the RF device. At the same time, when multiple SMD 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. The plugs 42 on both sides of the cooling box 41 can be opened to replace the cooling water inside the 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 sensor 453 under the elasticity of the extrusion belt 454. When the pressure sensor 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 moisture at the bottom of the cooling box 41, so that the hotter moisture at the top is fully mixed with the cold water at the bottom, avoiding the situation where the hotter moisture at the top cannot effectively exchange heat with the cold water at the bottom when the moisture is static, so that the placement plate 1 can only contact the moisture with gradually rising temperature, resulting in a reduction in the cooling effect.
