Description

Technical Field

[0001] This invention relates to the field of filter testing devices, and in particular to an automatic power-on testing system for power filters with self-positioning function. Background Technology

[0002] A power filter is a filtering circuit composed of capacitors, inductors, and resistors, also known as an "EMI power filter." It is a passive bidirectional network with one end connected to the power supply and the other end connected to the load. The greater the impedance matching between the input and output sides of the power filter and the power supply and load sides, the more effective it is attenuating electromagnetic interference. The filter can effectively filter out specific frequencies or frequencies outside of those frequencies in the power line to obtain a power signal of a specific frequency, or to eliminate a power signal of a specific frequency.

[0003] Power filters undergo several quality inspections from production completion to delivery, such as appearance inspection, withstand voltage, insulation, insertion loss testing, etc. Because power filters are prone to problems during production and assembly due to misoperation at a certain node or component failure, the power filters may malfunction during use, affecting normal use.

[0004] The existing solution is to set up inspection points at each stage to test the filter performance. However, current inspection points mostly rely on manual labor to test each filter individually in conjunction with the filter testing unit. This involves energizing both ends of the power filter to check its performance. In this process, most steps require workers to manually connect the wiring and move the components, fixing the power supply to the product's electrode contacts one by one to apply voltage. This operation has the following problems: The manual operation involves many steps, and over long periods of testing, errors are more likely to occur, affecting the accuracy and precision of the tests. The continuous and repetitive wiring and movement work done manually results in low testing efficiency and affects production. Manual operation carries certain risks. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic power-on detection system for a power filter with self-positioning function in order to solve the above-mentioned problems.

A pressure roller is mounted on the end of the V-shaped corner frame. A foot return spring is connected between the V-shaped corner frame and the end base frame. The lifting mechanism includes a sliding seat and a lifting drive side frame. The two ends of the sliding seat are mounted on the base frame. The two sides of the sliding seat are provided with a horizontal groove and a vertical groove. A vertical groove sliding arm is provided in the vertical groove, and a horizontal groove push arm is provided in the horizontal groove. A steering rod is rotatably mounted on one end of the horizontal groove push arm, and the end of the steering rod is rotatably mounted on the vertical groove sliding arm. An insulated lifting frame is mounted on the top of the vertical groove sliding arm, and the bottom of the vertical groove sliding arm is connected to the base frame through a pull spring. The bottom of the lifting drive side frame is slidably mounted on the base frame, and a lifting column is mounted on the lifting drive side frame. The end of the lifting column extends into the horizontal groove. The plug-in contact mechanism includes a bidirectional cylinder, which is installed at the bottom of the assembly plate. Plug-in side pressure frames are installed at both ends of the bidirectional cylinder, and insulated plug-in devices are provided on the plug-in side pressure frames.

[0007] Furthermore, the gap conveying mechanism includes a conveying roller frame, on which a gap conveying belt assembly is provided. The gap conveying belt assembly consists of several narrow conveying belts with gaps between them. The insulating jack is mounted in the gap of the narrow conveying belts, and the sliding seat is located between the two layers of the narrow conveying belt.

[0008] Furthermore, the lifting drive side frame is slidably mounted on the base frame via a side frame limiting rail, and a lead screw drive is mounted on the support frame. A bidirectional drive screw is mounted on the drive shaft of the lead screw drive, and the bidirectional drive screw is threadedly connected to two sets of the lifting drive side frames respectively.

[0009] Furthermore, the linkage assembly includes a clamping cylinder and an intermediate rod. The middle part of the intermediate rod is rotatably mounted to the assembly plate, and both ends of the intermediate rod are rotatably mounted with linkage rods. The ends of the two sets of linkage rods are respectively rotatably mounted to the two sets of clamping side frames, and the piston rod end of the clamping rod is connected to any of the clamping side frames.

[0010] Furthermore, the bottom of the clamping frame is slidably mounted to the assembly plate via the frame rail.

[0011] Furthermore, the two ends of the tripod return spring are respectively equipped with a base frame end lug and a corner frame end lug. The base frame end lug is installed on the bottom of the end base frame, and the corner frame end lug is installed on the V-shaped corner frame.

[0015] The beneficial effects are as follows: The automatic power-on detection system for power filters with self-positioning function described in this invention uses a positioning clamping mechanism to self-center and position the filter under test, which facilitates accurate subsequent docking with the insulated plug of the plug-in contact mechanism and improves the detection alignment accuracy. By separating the gap between the lifting mechanism and the gap conveying mechanism, the filter under test is separated from the gap conveying mechanism, and the filter after being energized is insulated, thereby improving the accuracy of energized detection. The plug-in contact mechanism can drive the insulated plug to make an electrical connection with the detection contact under the drive of the double-headed drive cylinder. Under the action of the top pressure spring, the connection is more stable and the contact is better. It can accurately and effectively test the power supply filter, with a high degree of automation, reducing manual intervention in the testing process, high testing efficiency, and relatively safe testing, making it suitable for mass production.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0019] The following is combined Figures 1 to 9 The automatic power-on detection system for power filters with self-positioning function provided in this embodiment will be further described as follows: Specific reference Figure 1-3 The embodiments of the present invention provide an automatic power-on detection system for power filters with self-positioning function, including a detection frame 100, a gap conveying mechanism 200, a disengagement lifting mechanism 300, a plug-in contact mechanism 400, and a positioning clamping mechanism 500. The testing frame 100 consists of a base frame 101, a top frame 103, and two sets of support frames 102 connected between the base frame 101 and the top frame 103. A filter testing main body 600 is installed on the top of the top frame 103. The filter testing main body 600 is connected to the plug-in contact mechanism 400 through a testing line 601. The gap conveying mechanism 200 is installed on the base frame 101. In this embodiment, two sets of support frames 102 are located at the two side edges of the base frame 101. The filter 700 to be tested is transported to the top of the release lifting mechanism 300 through the gap conveying mechanism 200. The release lifting mechanism 300 lifts the filter 700 to be tested. The positioning clamping mechanism 500 positions and clamps the filter 700 to be tested at the four sides. After the plug-in contact mechanism 400 is inserted into the contact point to be tested, the filter 700 to be tested is connected to the filter testing host body 600 for testing. Specific reference Figure 4 , Figure 6 The positioning and clamping mechanism 500 includes an assembly plate 501. Both sides of the assembly plate 501 are mounted on the support frame 102. Clamping side frames 503 are slidably mounted on both sides of the top surface of the assembly plate 501. The two sets of clamping side frames 503 are connected by a linkage component. Both ends of the clamping side frames 503 are equipped with end base frames 507. A V-shaped corner frame 508 is rotatably mounted on the bottom of the end base frame 507. A pressure roller 509 is installed at the end of the V-shaped corner frame 508. A foot return spring 510 is connected between the V-shaped corner frame 508 and the end base frame 507. In this embodiment, the filter to be tested 700 has a cuboid structure, and there are four sets of V-shaped brackets 508. When in use, the V-shaped structure is pressed onto the four corners of the filter to be tested 700. During the pressing process, the V-shaped brackets 508 rotate under force. When the bottom is disengaged from the lifting mechanism 300 and the lifting is removed, the V-shaped brackets 508 drive the filter to be tested 700 to reset under the action of the bracket reset spring 510, so that it can be aligned with the plug-in end of the plug-in contact mechanism 400. Specific reference Figure 5 , Figure 8 The lifting mechanism 300 includes a sliding seat 301 and a lifting drive side frame 302. The two ends of the sliding seat 301 are mounted on the base frame 101. The two sides of the sliding seat 301 are provided with a horizontal groove 312 and a vertical groove 311. A vertical groove sliding arm 310 is provided in the vertical groove 311, and a horizontal groove push arm 305 is provided in the horizontal groove 312. A steering rod 306 is rotatably mounted on one end of the horizontal groove push arm 305. The end of the steering rod 306 is rotatably mounted on the vertical groove sliding arm 310. An insulating lifting frame 303 is mounted on the top of the vertical groove sliding arm 310. The bottom of the vertical groove sliding arm 310 is connected to the base frame 101 through a pull spring 307. The bottom of the lifting drive side frame 302 is slidably mounted on the base frame 101. A lifting column 304 is mounted on the lifting drive side frame 302. The end of the lifting column 304 extends into the horizontal groove 312. In this embodiment, there are two sets of insulating lifting frames 303, both located above the sliding seat 301. The top surface of the sliding seat 301 is provided with a frame embedding groove adapted to the insulating lifting frame 303, which facilitates the entry of the insulating lifting frame 303 when it falls back. Each set of insulating lifting frames 303 requires two horizontal slot push arms 305, two steering rods 306, and two vertical slot sliding arms 310 for driving. The two horizontal slot push arms 305, two steering rods 306, and two vertical slot sliding arms 310 are symmetrically distributed on both sides of the sliding seat 301 to increase the balance and stability of the lifting process. There are two sets of lifting drive side frames 302, which are respectively placed on both ends of the sliding seat 301. When the lifting drive side frame 302 slides, the lifting column 304 presses against the horizontal slot push arm 305 in the horizontal slot, thereby driving the insulating lifting frame 303 to rise through the linkage effect and reset with the assistance of the return spring 307. Specific reference Figure 4 , Figure 7 The plug-in contact mechanism 400 includes a bidirectional cylinder 401, which is installed at the bottom of the assembly plate 501. Plug-in side pressure brackets 402 are installed at both ends of the bidirectional cylinder 401, and insulated plug-in devices 404 are provided on the plug-in side pressure brackets 402. In this embodiment, each set of plug-in side pressure frame 402 is provided with three insulated plugs 404, corresponding to the three-phase power filter. The outer layer of the insulated plug 404 is insulated and the inner layer is conductive, which facilitates signal transmission.

[0020] like Figure 1 - Figure 9 As shown, embodiments of the present invention also disclose the following various more optimized specific structures: Continue to refer to Figure 1 The gap conveying mechanism 200 includes a conveying roller frame 201, on which a gap conveying belt group 202 is provided. The gap conveying belt group 202 is composed of several narrow conveying belts with gaps between them. An insulating lifting frame 303 is provided in the gap of the narrow conveying belts to facilitate lifting and lowering without affecting the conveying of the gap conveying mechanism 200. A sliding seat 301 is provided between the two layers of the narrow conveying belt. The conveying roller frame 201 is also provided with a conveying drive device (not shown in the figure), which is one of the necessary accessories of the conveying belt structure and will not be described in detail here.

[0021] Continue to refer to Figure 2 , Figure 4 The lifting drive side frame 302 is slidably mounted on the base frame 101 via the side frame limiting rail 308. A screw drive component 313 is mounted on the support frame 102. A bidirectional drive screw 309 is mounted on the drive shaft of the screw drive component 313. The bidirectional drive screw 309 is threadedly connected to two sets of lifting drive side frames 303 respectively. The rotation is converted into displacement driving force for the lifting drive side frames 303, causing the two sets of lifting drive side frames 303 to move in opposite directions.

[0022] The linkage assembly includes a clamping cylinder 502 and an intermediate rod 504. The middle part of the intermediate rod 504 is rotatably mounted on the assembly plate 501. Both ends of the intermediate rod 504 are rotatably mounted with linkage rods 505. The ends of the two sets of linkage rods 505 are respectively rotatably mounted on two sets of clamping side frames 503. The piston rod end of the clamping rod 502 is connected to any clamping side frame 503.

[0023] The bottom of the clamping frame 503 is slidably mounted onto the assembly plate 501 via the frame rail 506.

[0024] Continue to refer to Figure 7 The two ends of the tripod return spring 510 are respectively equipped with a base frame end ear 511 and a corner frame end ear 512. The base frame end ear 511 is installed on the bottom of the end base frame 507, and the corner frame end ear 512 is installed on the V-shaped corner frame 508.

[0025] Specific reference Figure 9The insulated plug 404 includes an insulating cylinder 405, which is slidably inserted into the cylinder hole of the plug-in side pressure frame 402. A disc sleeve 407 is installed at one end of the insulating cylinder 405. A top pressure spring 409 is sleeved on the insulating cylinder 405 between the disc sleeve 407 and the plug-in side pressure frame 402 to facilitate close contact with the filter 700 under test. A power-conducting rod 406 is provided inside the insulating cylinder 405. One end of the power-conducting rod 406 extends into the disc sleeve 407 and is equipped with a contact plate 408. The other end of the power-conducting rod 406 extends to the outside of the insulating cylinder 405 and is threaded with a wiring nut 410 for fixing the detection line and also for use as a limit stop mechanism.

[0026] Continue to refer to Figure 4 The bottom of the assembly plate 510 is equipped with a top limiting slide rod 403, and the plug-in side pressure bracket 402 is provided with an auxiliary limiting slide hole. The top limiting slide rod 403 is inserted into the auxiliary limiting slide hole.

[0027] Specific reference Figure 5 The lifting column 304 is a threaded column, which is installed into the threaded column hole of the lifting drive side frame 302 by thread. One end of the threaded column is provided with a top head, and the other end of the threaded column is threadedly connected with a reinforcing nut. The design of the threaded column here can change its length of insertion into the groove.

[0028] like Figure 1 - Figure 9 The automatic power-on detection system for power filters with self-positioning function shown can automatically detect the filter to be tested. The detection frame 100, gap conveying mechanism 200, disengagement lifting mechanism 300, plug-in contact mechanism 400, positioning clamping mechanism 500, and filter detection main body 600 are controlled by a controller (not shown). The filter to be tested 700 is placed on the gap conveyor belt group 202 and conveyed above the disengagement lifting mechanism 300. The lifting drive side frame 302 drives the lifting column 304 to move under the drive of the lead screw drive 313 and the bidirectional drive screw 309. The lead screw drive 313 can be a motor, and the lifting column 304... The top-pressing horizontal slot push arm 305 drives the insulating lifting frame to rise via the steering rod 306 and the vertical slot sliding arm 310, causing the filter under test 700 to rise. The clamping cylinder 502 is activated, and the clamping side frame 503 drives the bottom V-shaped corner frame 508 to clamp onto the filter under test 700. At this time, under the action of the pull-back spring 307, the insulating lifting frame 303 falls back, and the foot frame reset spring 510 drives the V-shaped corner frame 508 and the filter under test 700 to align. The plug-in side pressure frames 402 on both sides move under the action of the bidirectional cylinder 401, and the end of the insulating plug 404 contacts and presses onto the detection contact of the filter under test 700, realizing communication with the filter detection host body and completing the detection.

[0029] The above structure has the following advantages: The positioning and clamping mechanism 500 performs self-centering positioning of the filter under test 700, which facilitates accurate subsequent docking with the insulating plug 404 of the plug-in contact mechanism 400 and improves the detection alignment accuracy. By disengaging the gap between the lifting mechanism 400 and the gap conveying mechanism 200, the filter under test 700 is separated from the gap conveying mechanism 200, and the filter after being energized is insulated to improve the accuracy of energized detection. The plug-in contact mechanism can drive the insulated plug to make an electrical connection with the detection contact under the drive of the dual-head drive cylinder. Under the action of the top pressure spring, the connection is more stable and the contact is better.

[0030] It can accurately and effectively test the power supply filter, with a high degree of automation, reducing manual intervention in the testing process, high testing efficiency, and relatively safe testing, making it suitable for mass production.

[0031] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
