Description

Technical Field

[0001] The invention relates to the technical field of radio frequency filter detection, and in particular to a radio frequency filter performance detection device. Background Art

[0002] Filters are a key component widely used in electronics, communications, electricity, medical and other fields. They are mainly used for signal processing and noise suppression. The performance and quality of filters are directly related to the stability and reliability of the system. In order to accurately evaluate the performance and reliability of filters, filters usually need to be tested after production.

[0003] In the detection of filters, only the performance and appearance of the filters are tested. Unqualified filters are not removed in time during the detection process. After the detection is completed, the detection results need to be screened and judged manually, which will not only increase the workload of operators and reduce the detection efficiency, but there are also human errors in the manual screening and judgment process, such as misjudgment, missed judgment, etc., which will affect the accuracy of the test results. When bad filters are confused with other qualified products, the overall product quality will be reduced. If bad filters are misused, it will directly reduce the stability and reliability of the entire system, and may even cause system failure or damage. Summary of the invention

[0050] The rotating mechanism 2 includes a mounting plate 21, the bottom of the mounting plate 21 is fixedly connected to the bottom of the inner wall of the housing 11, a group of guide rails 22 are fixedly installed on one side of the outer wall of the mounting plate 21, the outer wall of the group of guide rails 22 are movably sleeved with sliders 23, a moving seat 24 is fixedly installed between the outer walls of a group of sliders 23, a cylinder 25 is fixedly installed on the top of the mounting plate 21, a piston rod 26 is provided at the output end of the cylinder 25, and the top of the piston rod 26 is fixedly connected to the bottom of the moving seat 24, a motor 27 is fixedly installed on the top of the moving seat 24, and an electric clamp 28 is fixedly installed at the output end of the motor 27;

[0051] The moving mechanism 5 includes an electric telescopic rod 4 51, the bottom of which is fixedly connected to the bottom of the inner wall of the outer shell 11, a positioning rod 52 is fixedly installed on the telescopic end of the electric telescopic rod 4 51, a gear 1 53 is fixedly sleeved on the outer wall of the positioning rod 52, a clamp mounting frame 54 is movably sleeved on the outer wall of the positioning rod 52, two electric clamps 2 55 are fixedly installed on the bottom of the clamp mounting frame 54, a support seat 56 is fixedly installed on the top of the clamp mounting frame 54, a motor 4 57 is fixedly installed on the top of the support seat 56, a rotating shaft 58 is fixedly installed on the output end of the motor 4 57, and the outer wall of the rotating shaft 58 is movably inserted into the interior of the support seat 56, the outer wall of the rotating shaft 58 is fixedly sleeved with a gear 2 59, and the outer wall of the gear 2 59 is meshingly connected with the outer wall of the gear 1 53.

[0052] In this embodiment, the user can move the device to the work site through a set of universal wheels 14 at the bottom of the shell 11. When the position of the shell 11 is determined, people start the device through the control panel 15. At this time, a set of electric telescopic rods 12 start to start, so that the anti-slip pad 13 below continues to descend and contact the ground, avoiding the movement of the device during use. It can also reduce the pressure on the universal wheels 14 and extend its service life. After the user places the filter to be tested on one end of the qualified filter conveyor belt 19, the user can start the relevant equipment through the control panel 15. At this time, the qualified filter conveyor belt 19 adopts intermittent conveying to ensure that the filter stays under each device for a period of time. When the filter comes under the first visual inspection device 17, the visual inspection device 17 collects and processes image information of the top and part of the side of the filter through the camera below, and then converts the image information into digital signals and inputs them into the corresponding controller for processing. The controller uses image processing algorithms, feature extraction technology and defect recognition algorithms to analyze and process the images to determine whether there are defects, damages and other problems on the filter surface. Then the filter continues to move forward. When the filter comes under the electric clamp 28, the cylinder 25 will drive the piston rod 26 to contract, so that the moving seat 24 on the top of the piston rod 26 will drop synchronously. The moving seat 24 will drive the two sliders 23 to slide on the surfaces of the two guide rails 22. The sliders 23 and the guide rails 22 cooperate with each other to ensure that the movement direction of the moving seat 24 will not deviate. The movable seat 24 descends so that the electric clamp 28 is sleeved on the surface of the filter. Then the electric clamp 28 is started and the filter is clamped by contracting the two clamping blocks. The cylinder 25 pushes the electric clamp 28 and the filter up through the piston rod 26. At this time, the motor 27 is started and drives the filter to rotate 180 degrees. After the filter rotates, the cylinder 25 drives the filter down again through the piston rod 26 and the electric clamp 28 to contact the qualified filter conveyor belt 19. The electric clamp 28 cancels the clamping of the filter and rises, making it convenient for the qualified filter conveyor belt 19 to continue to transport the filter forward. Another visual inspection device 17 at the rear can inspect the bottom and part of the side of the filter. The filter that has been preliminarily inspected is flipped over by the rotating mechanism 2 so that the visual The detection device 17 can conduct a comprehensive inspection of the filter to ensure that no possible defects or damage are missed, which helps to improve the accuracy and completeness of the inspection. Then the filter continues to move forward. When the filter comes under the X-ray detection device 18, the X-ray detection device 18 can emit X-rays to accurately detect various problems in the filter, such as cracks, deformations or loose welding connections of components such as capacitors, inductors, and resistors, thereby improving the comprehensiveness of the inspection results. After the filter inspection is completed, the qualified filters are uniformly brought to the bottom of the electric clamp 2 55 by the conveyor belt 19. When the unqualified filters are brought to the bottom of the electric clamp 2 55, the electric telescopic rod 4 51 contracts and drives the electric clamp 2 55 to descend through the positioning rod 52 and the clamp mounting frame 54.Subsequently, the electric clamp 2 55 located on the side of the defective filter is started to clamp the defective filter, and the electric telescopic rod 4 51 rises accordingly, causing the defective filter to rise. At this time, the motor 4 57 is started, and the gear 2 59 is driven to rotate at a lower speed through the rotating shaft 58 to ensure that the two gears are always engaged. When the gear 2 59 rotates, it makes a circular motion driven by the gear 1 53 engaged with it, and drives the two electric clamps 2 55 and the clamped defective filter to rotate 180 degrees through the clamp mounting frame 54. At this time, the defective filter is located above the defective filter conveyor belt 20, and the electric telescopic rod 4 51 contracts to place the defective filter on the top of the defective filter conveyor belt 20, and the electric clamp 2 55 cancels the clamping of the defective filter, and the defective filter is removed. The filter conveyor belt 20 will drive the unqualified filters forward and automatically remove the unqualified filters from the qualified filters without manual confirmation or intervention, thereby speeding up the production process. It can also accurately and reliably identify and remove unqualified filters, reducing the possibility of human error, helping to maintain the overall quality of the product and improve customer satisfaction. When the unqualified filter is transported to the end of the unqualified filter conveyor belt 20, the laser engraving head 162 on the top is started, and different marks are engraved on its surface according to the defects detected by the filter, so that maintenance personnel can take corresponding maintenance strategies for different types of problems, such as replacing damaged components, adjusting filter parameters, cleaning the inside of the filter, etc., so as to more effectively solve the filter problems and improve the maintenance effect.

[0054] The detection mechanism 4 includes a group of electric telescopic rods 3 41, the outer walls of the group of electric telescopic rods 3 41 are fixedly connected to one side of the outer wall of the top plate 32, a movable plate 42 is fixedly installed between the telescopic ends of the group of electric telescopic rods 3 41, a motor 3 43 is fixedly installed on the top of the movable plate 42, a rotating shaft 44 is fixedly installed on the output end of the motor 3 43, and the outer wall of the rotating shaft 44 is movably inserted into the inside of the movable plate 42, a rotating table 45 is fixedly installed at the bottom of the rotating shaft 44, an air outlet pipe 46 is fixedly installed at the bottom of the rotating table 45, two sealing rings 47 are adhered to the outer wall of the air outlet pipe 46, a group of mounting holes 48 are opened on the outer wall of the rotating table 45, and plugs 49 are fixedly inserted on the inner walls of the group of mounting holes 48.

[0055] In this embodiment, when the filter comes under the positioning mechanism 3, a set of electric telescopic rods 31 will drive the top plate 32 to descend, so that the two mounting seats 314 are located outside the filter, and then the motor 33 is started, and the rotating force arm 35 starts to rotate through the rotating shaft 34, and the rotating force arm 35 drives the fixed rods 39 at both ends to start circular motion, and the fixed rods 39 respectively drive the connecting force arms 310 movably mounted on the outer wall to start moving, and the other end of the connecting force arm 310 starts to pull the connecting frame 38 toward the center through the fixed rod 313, driving the slider 37 to slide on the surface of the guide rail 36, and the fixed rod 313 and the mounting seat 314 located under the slider 37 drive the two sets of clamping wheels 317 to move together. When the two sets of clamping wheels 317 contact the two diagonals of the filter, the clamping wheels 317 start to slide on the surface of the filter, ensuring that each set of clamping wheels 317 is It can be accurately stuck on the two sides of the filter, and the two sets of clamping wheels 317 cooperate with each other to fix the filter at the center position of the qualified filter conveyor belt 19. Then the electric telescopic rod three 41 begins to shrink, and the two plugs 49 are inserted into the filter jack through the movable plate 42 and the rotating table 45. The performance of the filter is tested with the help of the equipment connected to the plug 49. After the test, the electric telescopic rod three 41 pushes the movable plate 42 away from the filter to pull the plug 49 out of the filter. Then the motor two 33 starts to reverse, driving the two sets of clamping wheels 317 away from the filter to release the clamping of the filter. The two sets of clamping wheels 317 can not only clamp the filter to prevent the filter from being displaced during testing and affecting the performance test results, but also ensure that the filter is fixed at the center position of the qualified filter conveyor belt 19 to prevent the filter socket from being unable to align with the plug 49.

[0056] Embodiment 3, according to Figure 1 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the detection mechanism 4 includes a group of electric telescopic rods 3 41, the outer walls of the group of electric telescopic rods 3 41 are fixedly connected to one side of the outer wall of the top plate 32, a movable plate 42 is fixedly installed between the telescopic ends of the group of electric telescopic rods 3 41, a motor 3 43 is fixedly installed on the top of the movable plate 42, a rotating shaft 44 is fixedly installed on the output end of the motor 3 43, and the outer wall of the rotating shaft 44 is movably inserted into the inside of the movable plate 42, a rotating table 45 is fixedly installed at the bottom of the rotating shaft 44, an air outlet pipe 46 is fixedly installed at the bottom of the rotating table 45, two sealing rings 47 are adhered to the outer wall of the air outlet pipe 46, a group of mounting holes 48 are opened on the outer wall of the rotating table 45, and plugs 49 are fixedly inserted into the inner walls of the group of mounting holes 48.

[0057] In this embodiment, before the plug 49 is inserted into the socket of the filter, the motor three 43 can be started first to drive the rotating shaft four 44 to rotate inside the movable plate 42. At this time, the rotating table 45 at the bottom of the rotating shaft four 44 rotates accordingly, driving the air outlet pipe 46 at the bottom of the rotating table 45 to come to the side of the filter socket, and the electric telescopic rod three 41 begins to shrink, so that the sealing ring 47 on the air outlet pipe 46 is sleeved on the interface, and then the high-speed flowing air is injected into the input end of the air outlet pipe 46, and the air is discharged through the other end. Since the air outlet pipe 46 is composed of three pipes connected by one horizontal and two vertical pipes, when there is rapid air flow inside the horizontal pipe, according to Bernoulli's principle, the air inside the two vertical pipes is discharged together. Since the sealing ring 47 of the two vertical pipes is adhered and sleeved on the interface, the dust and other pollutants in the interface will be discharged with the air. Removing the pollutants inside the interface can ensure good contact between the filter and the plug 49, which plays a role in reducing resistance, reducing signal attenuation, and improving the stability of current transmission, thereby improving the accuracy of the detection results.

[0058] The working principle of the whole mechanism is as follows: the user can easily move the device to the designated work place by means of the universal wheels 14 at the bottom of the housing 11. Once the position of the housing 11 is determined, the user can start the whole device through the control panel 15. At this time, a set of electric telescopic rods 12 will start, driving the anti-skid pad 13 below to slowly descend until it is in close contact with the ground, thereby effectively preventing the device from moving during use and reducing the burden of the universal wheels 14. Next, the user only needs to place the filter to be tested on one end of the qualified filter conveyor belt 19 and start the relevant equipment through the control panel 15. The qualified filter conveyor belt 19 adopts an intermittent conveying method to ensure that each filter can stay under the equipment for a sufficient time for inspection. When the filter moves to the bottom of the first visual inspection device 17, the device will capture and process the image information of the top and part of the side of the filter through the camera below it, and accurately judge whether there are defects or damages on the surface of the filter. Then, the filter will continue to move to the bottom of the electric clamp 28. At this time, the cylinder 25 will drive the piston rod 26 to contract, driving the moving seat 24 and the two sliders 23 to slide smoothly on the two guide rails 22 to ensure that the movement direction does not shift. As the moving seat 24 descends, the electric clamp 28 will be tightly wrapped around the surface of the filter and clamp it by contracting the clamping block. Then, the cylinder 25 pushes the electric clamp 28 and the filter up again through the piston rod 26, and the motor 27 starts to drive the filter to rotate 180 degrees, after the rotation is completed, the cylinder 25 drives the electric clamp 28 and the filter to descend again and contact with the qualified filter conveyor belt 19. At this time, the electric clamp 28 will release the filter so that the conveyor belt can continue to transport it forward. Another visual inspection device 17 will inspect its bottom and part of the side. Through the flipping action of the rotating mechanism 2, the filter can be fully inspected by the visual inspection device 17 to ensure that any possible defects or damage are found without omission. Subsequently, the filter will move to the bottom of the X-ray inspection device 18, which can emit X-rays to accurately detect cracks, deformations or loose welding connections of the internal components of the filter (such as capacitors, inductors, resistors, etc.), further improving the comprehensiveness of the inspection results. When the filter reaches the fixed When the filter is under the filter mechanism 3, a set of electric telescopic rods 31 will drive the top plate 32 to descend, so that the two mounting seats 314 are located outside the filter. Then, the motor 33 is started, and the rotating arm 35 and the fixing rods 39 at both ends start circular motion through the rotating shaft 34. This series of actions will drive the two sets of clamping wheels 317 to move closer and accurately clamp at the two diagonal corners of the filter, thereby fixing it in the center position of the qualified filter conveyor belt 19. Next, the electric telescopic rod 3 41 will shrink, and the sealing ring 47 on the air outlet pipe 46 will be put on the interface through the movable plate 42 and the rotating table 45. Then, the air outlet pipe 46 will be injected with high-speed flowing air, and the dust and other pollutants in the interface will be discharged by using the Bernoulli principle to ensure good contact between the filter and the plug 49.Improve the stability of current transmission and the accuracy of test results. Subsequently, the electric telescopic rod three 41 pushes the movable plate 42 to move outward, and the motor three 43 will start, driving the rotating shaft four 44 to rotate inside the movable plate 42, thereby driving the two plugs 49 at the bottom of the rotating table 45 to the side of the filter socket. At this time, the electric telescopic rod three 41 contracts, so that the two plugs 49 are inserted into the filter socket for performance testing. After the test is completed, the electric telescopic rod three 41 pushes the movable plate 42 away from the filter again, so that the plugs 49 are pulled out from the inside of the filter. Subsequently, the motor two 33 reverses, drives the two sets of clamping wheels 317 away from the filter and releases the clamping. After the filter test is completed, the qualified filters will be uniformly brought to the bottom of the electric clamp two 55 by the qualified filter conveyor belt 19. For unqualified filters, when they are brought to the bottom of the electric clamp two 55, the electric telescopic rod four 51 will contract and drive the electric clamp two 55 to descend and clamp through the positioning rod 52 and the clamp mounting frame 54. The unqualified filter is clamped tightly, and then the electric telescopic rod 4 51 is raised to make the unqualified filter rise. At this time, the motor 4 57 is started and drives the gear 2 59 to rotate at a lower speed through the rotating shaft 58. Driven by the gear 1 53, the electric clamp 2 55 and the clamped unqualified filter will rotate 180 degrees and move above the unqualified filter conveyor belt 20. Then, the electric telescopic rod 4 51 is retracted to place the unqualified filter on the top of the conveyor belt and release the clamping. The unqualified filter conveyor belt 20 will drive it forward to the end. At this time, the laser engraving head 162 on the top will engrave different marks on the filter surface according to the detected defects, so that the maintenance personnel can adopt corresponding maintenance strategies for different problems. The whole process does not require manual confirmation or intervention, which not only speeds up the production process, but also can accurately and reliably identify and remove unqualified filters, reduce the possibility of human errors, and help maintain the overall quality of the product and improve customer satisfaction.
