[0008] Preferably, a connecting rod is installed on the clamping block, and a connecting rod is also installed on the sealing cover. One end of the telescopic rod is rotatably installed on the connecting rod of the clamping block, and the other end of the telescopic rod is rotatably installed on the connecting rod of the sealing cover.

[0009] Preferably, a first spring is installed inside the first storage box.

[0014] Preferably, a second groove is provided on the rotating platform, a second moving plate is slidably installed at one end of the second groove, and a handle is also installed on the second moving plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. While the threaded rod drives the two clamping blocks to move relatively, the two clamping blocks drive the telescopic rod to adjust the angle through the connecting rod. The telescopic rod drives the sealing cover to close on the rotating platform, so that the detection environment of the rotating platform 1 is in a sealed state. The sealed environment can effectively reduce some gas and particle pollution or electromagnetic interference existing in the natural environment, etc., and can significantly improve the test accuracy, reliability and detection efficiency of the radio frequency switch chip.

[0017] 2. In the present invention, two sets of sealing covers drive the pressing blocks to press downwards. The pressing blocks press the pushing blocks, causing the pushing blocks to push the first push plate through the push rods. The first push plate presses the cleaning agent in the first storage box inside, enabling the cleaning agent to be sprayed onto the RF chip through the nozzle, removing the oil stains on the RF switch chip, and preventing the oil stains from affecting the detection of the RF switch chip.

[0018] 3. In the present invention, when the first inclined block rotates and is squeezed by the second inclined block, the moving frame moves on the first groove through the slider, causing the first inclined block to drive the moving frame to move on the rotating platform. Thus, the moving frame drives the moving rod to move, centering and positioning the RF switch chip, preventing the RF switch chip from displacing due to centrifugal force when the rotating platform rotates, and ensuring that the detection has no error.

[0019] 4. While the moving frame is moving, the present invention drives the second push plate to move inside the second storage box through the first moving plate, squeezing the nitrogen gas inside the second storage box. The nitrogen gas inside the second storage box is transmitted to the inside of the sealing cover through the nozzle, inflating and pressurizing the inside of the sealing cover, increasing the air pressure inside the sealing cover, facilitating the extrusion and discharge of the air inside the sealing cover. At the same time, the detection personnel open the second moving plate to connect the first groove with the outside, discharging the air inside the sealing cover. Filling with nitrogen can on the one hand air-dry the cleaning agent on the RF switch chip, improving its cleaning efficiency and preventing residual cleaning agent from affecting the detection. At the same time, the filled nitrogen gas flows around the clamping assembly, reducing the thermal coupling generated due to mutual friction during the clamping process between the clamping assembly and the RF switch chip.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0029] Refer to Figures 1 to 4 As shown, the present invention provides a tester for a radio frequency switch chip, including a rotating platform 1. A clamping assembly 2 is installed on the rotating platform 1. The clamping assembly 2 includes a threaded rod 201. Two groups of clamping blocks 202 are slidably installed on the threaded rod 201. An expansion link 203 is installed on the two groups of clamping blocks 202. One end of the expansion link 203 is installed with a sealing cover 205. One side of the sealing cover 205 is rotatably connected to a first storage box 206. One side of the first storage box 206 is fixedly installed on the rotating platform 1. Two groups of first push plates 208 are installed inside the first storage box 206. A push rod 209 is installed on one side of the first push plate 208. One end of the push rod 209 is connected to a push block 210. An extrusion block 211 is slidably connected to the push block 210;

[0030] When the tester places two radio frequency switch chips on the rotating platform 1 at the same time, the tester rotates the threaded rod 201 through the 214 handle. The threaded rod 201 drives the two groups of clamping blocks 202 to move relatively to clamp and fix the radio frequency switch chips. While the threaded rod 201 drives the two groups of clamping blocks 202 to move relatively, the two groups of clamping blocks 202 drive the expansion link 203 to adjust the angle through the connecting rod. The expansion link 203 drives the sealing cover 205 to close, so that the detection environment of the rotating platform 1 is in a sealed state. The sealed environment can effectively reduce some gas and particle pollution or electromagnetic interference existing in the natural environment, etc., and can significantly improve the test accuracy, reliability and detection efficiency of the radio frequency switch chip;

[0031] While the telescopic rod 203 drives the sealing cover 205 to close on the rotating platform 1, the two groups of sealing covers 205 drive the extrusion block 211 to press downwards. The extrusion block 211 presses the push block 210, causing the push block 210 to push the first push plate 208 through the push rod 209. The first push plate 208 presses the cleaning agent in the internal first storage tank 206, enabling the cleaning agent to spray the cleaning agent onto the RF chip through the nozzle 212, removing the oil stain on the RF switch chip and preventing the oil stain from affecting the detection of the RF switch chip.

[0032] When the first storage tank 206 is full of the cleaning agent, the cleaning agent will press the first push plate 208, causing the first spring 207 to stretch. When the first push plate 208 is driven by the push rod 209 to press the cleaning agent, the spring deforms and compresses. After the RF switch chip is detected, the two groups of sealing covers 205 are opened, and the sealing covers 205 drive the extrusion block 211 to leave the push block 210. The push rod 209 no longer receives the pressure from the push rod 209 through the push block 210. The spring drives the push rod 209 to rebound through the first push plate 208, so that the push rod 209 drives the push block 210 to reset, facilitating the removal of oil stains during the detection of the next group of RF switch chips.

[0033] Refer to Figures 5 to 7 As shown in the figure, the rotating platform 1 is installed with four groups of protection components 3. The protection component 3 includes a moving frame 301 slidably installed on the rotating platform 1. A moving rod 303 is installed inside the moving frame 301. One side of the moving frame 301 is fixedly connected to a first moving plate 308. A second push plate 309 is fixedly installed on one side of the first moving plate 308. A second storage tank 310 is installed outside the second push plate 309. The second storage tank 310 is fixedly installed on the rotating platform 1. A first inclined block 304 is fixedly installed on one side of the moving frame 301. A second inclined block 305 is slidably connected to one side of the first inclined block 304. The second inclined block 305 is fixedly installed on the rotating platform 1.

[0034] When the tester places the two groups of RF switch chips on the rotating platform 1 at the same time and after the clamping component 2 finishes working, the tester rotates the rotating platform 1, facilitating the sequential detection of the two groups of RF switch chips and facilitating the detection of the RF switch chip 1 without dead angles.

[0035] When the tester rotates the rotating platform 1, it drives the first inclined block 304 to rotate. Under the extrusion of the second inclined block 305, the moving frame 301 moves on the rotating platform 1 through the slider on the first groove, so that the first inclined block 304 drives the moving frame 301 to move on the rotating platform 1. Thus, the moving frame 301 drives the moving rod 303 to move, centering and positioning the RF switch chip, preventing the RF switch chip from shifting due to centrifugal force when the rotating platform 1 is rotated, and ensuring that the detection is accurate.

[0036] When the moving rod 303 touches the RF switch chip, if the pressure exerted by the moving rod 303 is too large, the second spring 302 will be compressed, reducing the pressure exerted by the moving rod 303 and preventing excessive centering pressure that could damage the RF switch chip.

[0037] When the tester rotates the rotating platform 1, the first inclined block 304 is driven to rotate. Under the extrusion of the second inclined block 305, the first inclined block 304 drives the moving frame 301 to move on the rotating platform 1. By means of the slider, the third spring 307 inside the first groove is compressed. When the first inclined block 304 rotates away from the second inclined block 305 and is no longer extruded by the second inclined block 305, the third spring 307 drives the moving frame 301 to rebound. Thus, the moving frame 301 moves reciprocally. While the moving frame 301 is moving, the second push plate 309 is driven by the first moving plate 308 to move inside the second storage box 310, squeezing the nitrogen gas inside the second storage box 310. The nitrogen gas inside the second storage box 310 is transmitted through the nozzle 212 into the sealing cover 205, inflating and pressurizing the inside of the sealing cover 205, increasing the air pressure inside the sealing cover 205, and facilitating the extrusion and discharge of the air inside the sealing cover 205.

[0038] At the same time, the tester opens the second moving plate 311 to connect the first groove to the outside, exhausting the air inside the sealing cover 205. Filling with nitrogen can, on the one hand, air-dry the cleaning agent on the RF switch chip, improving its cleaning efficiency and preventing residual cleaning agent from affecting the detection. At the same time, the nitrogen gas filled reduces the thermal coupling generated by mutual friction during the clamping process between the clamping assembly 2 and the RF switch chip.

[0039] On the other hand, after a certain period of time, a certain amount of air inside the sealing cover 205 is discharged to maintain the air pressure stability inside the sealing cover 205. The tester closes the second moving plate 311, and nitrogen gas continues to be transmitted into the sealing cover 205 through the nozzle 212. The filling of nitrogen can increase the nitrogen concentration in the detection environment, reduce some gas and particle pollution or electromagnetic interference that may exist in the natural environment, and then continuously filling can change the pressure of the detection environment, increasing the diversity of detection. When the pressure inside the sealing cover 205 exceeds the normal pressure that the RF switch chip can withstand, the tester opens the second moving plate 311 again, and a part of the nitrogen gas is discharged to make the nitrogen pressure inside the sealing cover 205 reach an equilibrium state.

[0040] The nitrogen gas discharged to the outside can be connected to a collection device to collect the discharged nitrogen gas.

[0041] The clamping assembly 2 clamps and fixes the RF switch chip, and at the same time drives the two sealing covers 205 to close, so that the detection environment of the rotating platform 1 is in a sealed state. The sealed environment can effectively reduce gas and particle pollution or electromagnetic interference that may exist in the natural environment, etc., and can significantly improve the test accuracy, reliability and detection efficiency of the RF switch chip. At the same time, the cleaning agent inside the first storage box 206 is squeezed by the two sealing covers 205, and the cleaning agent is sprayed onto the RF chip to remove the oil stain on the RF switch chip and prevent the oil stain from affecting the detection of the RF switch chip. Then, while rotating the rotating platform 1, the protection assembly 3 reciprocates to center the RF switch chip, preventing the RF switch chip from shifting due to centrifugal force when the rotating platform 1 is rotated, resulting in detection errors. While the protection assembly 3 reciprocates, it inflates and pressurizes the inside of the sealing cover 205. On the one hand, the nitrogen gas filled can accelerate the drying of the cleaning agent on the RF switch chip and prevent the residual cleaning agent from affecting the detection. At the same time, the nitrogen gas filled flows around the clamping assembly 2 to reduce the thermal coupling generated by mutual friction during the clamping of the clamping assembly 2 and the RF switch chip. On the other hand, the filling of nitrogen gas can increase the nitrogen concentration in the detection environment and reduce gas and particle pollution or electromagnetic interference that may exist in the natural environment, etc. Then, continuous filling can change the pressure of the detection environment and increase the diversity of detection.

[0042] In an optional embodiment, the rotating platform 1 is divided into upper and lower layers. One end of the threaded rod 201 is provided with a handle 214. When the tester places the two RF switch chips on the rotating platform 1 at the same time, the tester rotates the threaded rod 201 through the handle 214, and the threaded rod 201 drives the two clamping blocks 202 to move relatively to clamp and fix the RF switch chip. The rotating platform 1 being divided into upper and lower layers facilitates the staff to rotate.

[0043] In an optional embodiment, a connecting rod is installed on the clamping block 202, and a connecting rod is also installed on the sealing cover 205. One end of the telescopic rod 203 is rotatably installed on the connecting rod of the clamping block 202, and the other end of the telescopic rod 203 is rotatably installed on the connecting rod of the sealing cover 205. The two clamping blocks 202 drive the telescopic rod 203 to adjust the angle through the connecting rod, and the telescopic rod 203 drives the sealing cover 205 to close on the rotating platform 1, so that the detection environment of the rotating platform 1 is in a sealed state. The sealed environment can effectively reduce gas and particle pollution or electromagnetic interference that may exist in the natural environment, etc., and can significantly improve the test accuracy, reliability and detection efficiency of the RF switch chip.

[0044] In an alternative embodiment, a first spring 207 is installed inside the first storage box 206. One end of the first spring 207 is fixedly connected to the first storage box 206, and the other end of the first spring 207 is fixedly connected to the first push plate 208. One side of the push rod 209 extends through the first storage box 206 for installation, and one end of the push rod 209 is connected to the push block 210. The first storage box 206 is filled with a cleaning agent, and the cleaning agent will squeeze the first push plate 208, causing the first spring 207 to stretch. When the cleaning agent is squeezed by driving the first push plate 208 through the push rod 209, the spring deforms and compresses. After the radio frequency switch chip finishes detection, the two sealing covers 205 are opened, and the sealing covers 205 drive the extrusion block 211 away from the push block 210. The push rod 209 no longer receives the pressure of the push rod 209 through the push block 210. The spring drives the push rod 209 to rebound through the first push plate 208, so that the push rod 209 drives the push block 210 to reset, facilitating the removal of oil stains during the detection of the next group of radio frequency switch chips.

[0045] In an alternative embodiment, the extrusion block 211 is installed on the sealing cover 205. The two sealing covers 205 drive the extrusion block 211 to press down to transmit power. A nozzle 212 is connected to the first storage box 206, and the cleaning agent sprays the cleaning agent onto the radio frequency chip through the nozzle 212 to remove the oil stains on the radio frequency switch chip and prevent the oil stains from affecting the detection on the radio frequency switch chip.

[0046] In an alternative embodiment, a first groove is provided on the rotating platform 1, and a slider is provided at the lower end of the moving frame 301. The moving frame 301 is slidably installed on the first groove through the slider. The moving frame 301 moves on the first groove through the slider, so that the first inclined block 304 drives the moving frame 301 to move on the rotating platform 1, and thus the moving frame 301 drives the moving rod 303 to move for centering the radio frequency switch chip. One side of the slider is fixedly connected to a third spring 307, and one end of the third spring 307 is fixedly connected to the first groove. By squeezing the third spring 307 inside the first groove through the slider, the third spring 307 is compressed. When the first inclined block 304 rotates away from the second inclined block 305 and no longer receives the extrusion of the second inclined block 305, the third spring 307 drives the moving frame 301 to rebound, and so on, causing the moving frame 301 to move reciprocally.

[0047] In an alternative embodiment, a second spring 302 is fixedly connected inside the moving frame 301. One end of the second spring 302 is fixedly connected to a moving rod 303. By the slider squeezing the third spring 307 inside the first groove, the third spring 307 is compressed. When the first inclined block 304 rotates away from the second inclined block 305 and is no longer squeezed by the second inclined block 305, the third spring 307 drives the moving frame 301 to rebound. Thus, the moving frame 301 moves reciprocally. A support rod 306 is fixedly connected to one side of the second inclined block 305, and the support rod 306 is fixedly connected to the rotating platform 1 on one side. The support rod 306 is used to fix the second inclined block 305.

[0048] In an alternative embodiment, the moving frame 301 is fixedly connected to the first moving plate 308 through a connecting rod. The first moving plate 308 is slidably installed on one side of the second storage box 310. A spray head 212 is also communicated with one side of the second storage box 310. By the first moving plate 308 driving the second push plate 309 to move inside the second storage box 310, the nitrogen gas inside the second storage box 310 is squeezed, so that the nitrogen gas inside the second storage box 310 is transmitted to the inside of the sealing cover 205 through the spray head 212, and the inside of the sealing cover 205 is inflated and pressurized, so that the air pressure inside the sealing cover 205 increases, which is convenient for squeezing and discharging the air inside the sealing cover 205.

[0049] In an alternative embodiment, a second groove is provided on the rotating platform 1. A second moving plate 311 is slidably installed at one end of the second groove. A handle 214 is also installed on the second moving plate 311. The tester opens the second moving plate 311 through the handle 214 to communicate the first groove with the outside world, and discharges the air inside the sealing cover 205. Filling with nitrogen gas can, on the one hand, air-dry the cleaning agent on the RF switch chip, improve its cleaning efficiency, and prevent residual cleaning agent from affecting the detection.

[0050] Working principle: When the tester places two groups of RF switch chips on the rotating platform 1 at the same time, the tester rotates the threaded rod 201 through the handle 214. The threaded rod 201 drives the two groups of clamping blocks 202 to move relatively, clamping and fixing the RF switch chips. While the threaded rod 201 drives the two groups of clamping blocks 202 to move relatively, the two groups of clamping blocks 202 drive the telescopic rod 203 to adjust the angle through the connecting rod. The telescopic rod 203 drives the sealing cover 205 to close, so that the detection environment of the rotating platform 1 is in a sealed state. The sealed environment can effectively reduce some gas and particle pollution or electromagnetic interference that exist in the natural environment, etc., and can significantly improve the test accuracy, reliability and detection efficiency of the RF switch chip;

[0051] While the telescopic rod 203 drives the sealing cover 205 to close, the two groups of sealing covers 205 drive the pressing block 211 to press downwards. The pressing block 211 presses the pushing block 210, so that the pushing block 210 pushes the first push plate 208 through the push rod 209. The first push plate 208 presses the cleaning agent in the internal first storage tank 206, so that the cleaning agent sprays the cleaning agent onto the RF chip through the nozzle 212, removing the oil stain on the RF switch chip and preventing the oil stain from affecting the detection of the RF switch chip;

[0052] When the tester places the two groups of RF switch chips on the simultaneous rotation platform 1 and the clamping assembly 2 finishes working, the tester rotates the rotation platform 1, which facilitates the sequential detection of the two groups of RF switch chips and the all-round detection of the RF switch chip 1 without dead angles;

[0053] When the tester rotates the rotation platform 1, the first inclined block 304 is driven to rotate. Under the extrusion of the second inclined block 305, the moving frame 301 moves on the first groove through the slider, so that the first inclined block 304 drives the moving frame 301 to move on the rotation platform 1. Thus, the moving frame 301 drives the moving rod 303 to move, centering and positioning the RF switch chip, and preventing the RF switch chip from displacing due to centrifugal force when the rotation platform 1 rotates, resulting in detection errors;

[0054] When the tester rotates the rotation platform 1, the first inclined block 304 is driven to rotate. Under the extrusion of the second inclined block 305, the first inclined block 304 drives the moving frame 301 to move on the rotation platform 1. The third spring 307 inside the first groove is compressed by the slider, causing the third spring 307 to compress. When the first inclined block 304 rotates away from the second inclined block 305 and is no longer extruded by the second inclined block 305, the third spring 307 drives the moving frame 301 to rebound. Thus, the moving frame 301 moves reciprocally. While the moving frame 301 is moving, the second push plate 309 is driven to move inside the second storage tank 310 through the first moving plate 308, squeezing the nitrogen gas inside the second storage tank 310. The nitrogen gas inside the second storage tank 310 is transmitted to the inside of the sealing cover 205 through the nozzle 212, filling the inside of the sealing cover 205 with gas and increasing the air pressure inside the sealing cover 205, which facilitates the extrusion and discharge of the air inside the sealing cover 205. At the same time, the tester opens the second moving plate 311 to connect the first groove with the outside and discharge the air inside the sealing cover 205. Filling with nitrogen can dry the cleaning agent on the RF chip, improve its cleaning efficiency, and prevent residual cleaning agent from affecting the detection. At the same time, the nitrogen gas filled reduces the thermal coupling generated by the mutual friction between the clamping assembly 2 and the RF switch chip during the clamping process;

[0055] On the other hand, a certain amount of air inside the sealing cover 205 is discharged to keep the air pressure inside the sealing cover 205 stable. The tester closes the second moving plate 311, and nitrogen is continuously transmitted into the sealing cover 205 through the nozzle 212. The charging of nitrogen can increase the nitrogen concentration in the detection environment, reduce some gas and particle pollution or electromagnetic interference that may exist in the natural environment, etc. Then, continuous charging can change the pressure of the detection environment and increase the diversity of detection. When the pressure inside the sealing cover 205 exceeds the pressure that the normal radio frequency switch chip can withstand, the tester opens the second moving plate 311 again, and a part of the nitrogen is discharged to make the nitrogen pressure inside the sealing cover 205 reach an equilibrium state.

[0056] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
