Description

Technical Field

[0001] The invention belongs to the technical field of filter testing equipment, and in particular relates to a continuous performance testing device for filter production. Background Art

[0002] A filter is an electronic or physical device used to select or suppress signal frequency components. Its main function is to allow certain frequencies to pass through while blocking or weakening other frequencies. Filters are widely used in electronics, communications, audio, image processing and other fields. Different types of filters have different connection methods during the test process. In order to facilitate the connection of different devices, the input and output terminals on both sides of the filter are designed to be diverse, including lead type, pin type, solder piece type, bolt type, terminal type and socket type.

[0003] When the performance of the existing solder chip filter is tested, the filter is first fixed by a fixture, and the staff holds two test pens and touches the input and output terminals of the filter with the two pen ends respectively, so that the test signal enters from the input terminal and flows out from the output terminal, and the display is observed to complete the measurement. Although this measurement method is convenient and fast, and filters of different sizes can be measured, the measurement efficiency is low and a large number of filters cannot be tested quickly. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a continuous performance testing device for filter production.

[0005] The technical solution adopted to solve the above technical problems is: a continuous performance test device for filter production, comprising a workbench, a tester is fixedly installed at the top rear end of the workbench, and a plurality of fixed frames are fixedly connected to the top front end of the workbench;

[0006] A plurality of positioning mechanisms are provided at the top center of the workbench, a plurality of the fixed frames are each equipped with a clamping mechanism, and the plurality of positioning mechanisms are respectively close to the rear end position of the corresponding clamping mechanism;

[0007] Pushing mechanisms are installed on both sides of the top of the workbench close to the multiple fixed frames, and multiple testing mechanisms are installed on the two pushing mechanisms. Multiple filter bodies are arranged at the front end of the top of the workbench.

[0008] Furthermore, a placement groove is provided at the top center of the workbench, and a baffle is fixedly connected to the rear end of the placement groove.

[0009] Through the above technical solution, when testing the filter body, multiple filter bodies can be placed in the placement groove, one of which is close to the baffle, and the other two are close to the corresponding fixed frame, so that multiple positioning mechanisms can clamp and position it, which is convenient for multiple testing mechanisms to test the corresponding filter body.

[0010] Furthermore, the positioning mechanism includes two mounting grooves opened on the top of the workbench, the two mounting grooves are respectively located on both sides of the placement groove, two first sliding grooves are provided at the bottom of the two mounting grooves, the inner end surfaces of the two mounting grooves are fixedly connected with multiple first springs, the outer ends of the multiple first springs are fixedly connected with positioning blocks, the bottoms of the two positioning blocks are fixedly connected with two sliding blocks, and every two sliding blocks are respectively slidably connected to the corresponding first sliding grooves.

[0011] Through the above technical scheme, when the filter body squeezes the two positioning blocks downward, the two positioning blocks squeeze the multiple first springs that are connected to each other, and under the limitation of the two sliders and the corresponding first slide grooves, the two positioning blocks move toward the corresponding installation groove direction, and when the bottom of the filter body fits with the bottom end of the placement groove, the two positioning blocks clamp the two sides of the filter body under the action of the corresponding first spring elastic force to achieve positioning, which is convenient for the subsequent clamping mechanism to clamp and fix it, and at the same time, filter bodies of different sizes can be clamped and positioned, so that filter bodies of different sizes can be tested, and the functionality is strong.

[0012] Furthermore, the clamping mechanism includes a first threaded seat fixedly connected to the inner wall of the rear end of the fixed frame, the first threaded seat is internally threaded with a first threaded rod, and the rear end of the first threaded rod is fixedly connected to a bonding plate.

[0013] Through the above technical solution, after the filter body is clamped and positioned, the first threaded rod is rotated so that the first threaded rod drives the bonding plate to be closely attached to the front end of the filter body, and is further fixed under the action of the baffle or the fixing frame.

[0014] Furthermore, the bottom ends of both sides of the multiple filter bodies are respectively fitted with the corresponding positioning blocks, the front ends of the multiple filter bodies are respectively fitted with the corresponding fitting plates, the rear end of one of the filter bodies is fitted with the baffle, and the rear ends of the other two filter bodies are fitted with the corresponding fixed frames.

[0015] Through the above technical solution, multiple filter bodies can be positioned and fixed at the same time, so that multiple filter bodies can be tested at the same time, which greatly improves the test efficiency. Before positioning, multiple filter bodies need to be fitted with baffles or corresponding fixed frames to facilitate subsequent positioning and clamping.

[0016] Furthermore, the pushing mechanism includes two guide rails fixedly connected to one side of the front end of the top of the workbench, a movable seat is installed between the two guide rails, two fixed seats are fixedly connected to one side of the front end of the top of the workbench, cylinders are fixedly installed on the two fixed seats, one end of the two cylinder pistons is fixedly connected to the movable seat, a plurality of mounting seats are fixedly connected to the top of the movable seat, and a plurality of positioning arc grooves are provided on both sides of the inner walls of the plurality of mounting seats.

[0017] Through the above technical solution, when multiple filter bodies are positioned and clamped, the corresponding test mechanisms are inserted into the corresponding mounting seats and the corresponding adjustments are completed, the two cylinders are started at this time so that the pistons of the two cylinders push the connected movable seats, so that the movable seats drive the connected multiple mounting seats to move, thereby driving the test mechanism to move. Similarly, another pushing mechanism is started at the same time, so that the test mechanism is connected to the terminals on both sides of the filter body to realize the test.

[0018] Further, the testing mechanism includes a mounting block arranged in the mounting seat, multiple circular grooves are opened on both sides of the mounting block, multiple second springs are fixedly connected in the circular grooves, and the outer ends of multiple second springs are fixedly connected with positioning beads, the top of the mounting block is fixedly connected with a shell, the bottom inner surface of the shell is opened with two second slide grooves, the top of the shell is provided with a pointer, a mounting shell is slidably connected in the shell through the two second slide grooves, one side of the mounting shell is fixedly connected with a second threaded seat, the center of the second threaded seat is threaded with a second threaded rod, the second threaded rod is rotatably connected to the shell, and two limit bars are fixedly connected to the bottom inner surface of the mounting shell, two splints are provided in the mounting shell, the bottom and top of the two splints are opened with two limit grooves, one end of the two splints is sleeved with an arc rubber sleeve, and two third springs are fixedly connected between the two splints, a rectangular groove is opened in the center of one of the splints, a conductive spring sheet is installed in the rectangular groove, and an electric wire is fixedly connected between the conductive spring sheet and the tester.

[0019] Through the above technical scheme, before the test, the entire shell and the internal parts are inserted into the specified position in the mounting seat through the mounting block. At this time, multiple positioning beads move inward under the action of the corresponding second spring. When the mounting seat is installed, multiple positioning beads fit with the corresponding positioning arc grooves to achieve positioning and fixation. When the pointer is not aligned with the terminal on one side of the filter body, the second threaded rod is rotated at this time, so that the second threaded rod rotates to drive the second threaded seat to move, thereby driving the mounting shell to move in the shell, and then driving the two clamping plates to move, so that the pointer is aligned with the terminal on one side of the filter body, completing fine-tuning, so that the two clamping plates can clamp the terminals on one side of the filter body more accurately, and the conductive spring sheet can fully contact the terminal, so that the test signal can be accurately transmitted, which needs to be aligned with the filter body. When the terminals on the filter body are connected, the two clamping plates are driven to move toward the terminals on the filter body side under the push of the pushing mechanism. Since the inner surfaces of the two arc-shaped rubber sleeves are arc-shaped, the terminals on the filter body side are inserted between the two arc-shaped rubber sleeves. Under the action of the limit strip and the limit groove, the two arc-shaped rubber sleeves drive the connected clamping plates to be spread apart. When the pushing mechanism continues to push, the conductive spring sheets on one of the clamping plates fit with the terminals on the filter body side. During the test, the test signal is transmitted to the terminals on the filter body side through the wires and the conductive spring sheets to realize the test. After the test, the pushing mechanism is reset, and the two clamping plates are separated from the terminals on the filter body side. Under the action of the two third springs, the two clamping plates are reset to facilitate the connection of the terminals on the next filter body.

[0020] Furthermore, the plurality of positioning beads are respectively fitted with corresponding positioning arc grooves, and the plurality of limiting grooves are respectively slidably connected with corresponding limiting strips.

[0021] Through the above technical solution, the terminal positions on filter bodies of different sizes are also different. The staff can install the mounting blocks according to the specific positions of the terminals on both sides of the filter body, so that the two clamps can accurately clamp the terminals on the filter body. Multiple positioning beads are respectively fitted with the corresponding positioning arc grooves, and at the same time, the mounting blocks are fitted with the corresponding inner walls of the mounting seats, which greatly improves the stability of the outer shell and prevents the two clamps from shifting during the clamping process.

[0022] Furthermore, in the assembled state, the two clamping plates are fitted with the terminals on the filter body, and the conductive spring sheets are fitted with the terminals on the filter body.

[0023] Through the above technical solution, when the filter body is tested, the two clamps on one side of the test mechanism clamp the input terminal of the filter body, and the two clamps on the other side of the test mechanism clamp the output terminal of the filter body, so that the test signal is transmitted to the input terminal through the wire and the conductive spring sheet, and then enters the filter body. After the test, it flows from the output terminal to the tester through the wire, completing the entire test process.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can test multiple filter bodies at the same time by designing a test mechanism, and can perform precise fine-tuning before testing, so that the conductive spring sheet can be accurately connected to the terminal on the filter body, thereby improving the test accuracy value, and can connect terminals at different specific positions on the filter body, with strong functionality; (2) The present invention can position and clamp filter bodies of different sizes by designing a positioning mechanism and a clamping mechanism, so that the test mechanism can test filter bodies of different sizes, with strong functionality, and can position and fix multiple filter bodies at one time, with high efficiency.

Similarly, another driving mechanism 6 is started at the same time, so that the test mechanism 7 is connected to the terminals on both sides of the filter body 8 to realize the test.

[0039] like Figure 1-Figure 8As shown, a plurality of test mechanisms 7 are installed on the two pushing mechanisms 6, and the test mechanisms 7 include a mounting block 701 arranged in a mounting seat 605, a plurality of circular grooves 702 are provided on both sides of the mounting block 701, a second spring 703 is fixedly connected in the plurality of circular grooves 702, a positioning bead 704 is fixedly connected to the outer ends of the plurality of second springs 703, a housing 705 is fixedly connected to the top of the mounting block 701, two second slide grooves 706 are provided on the bottom inner surface of the housing 705, a pointer 707 is provided on the top of the housing 705, a mounting shell 708 is slidably connected in the housing 705 and through the two second slide grooves 706, a second threaded seat 709 is fixedly connected to one side of the mounting shell 708, and a second threaded rod is threadedly connected to the center of the second threaded seat 709 710, the second threaded rod 710 is rotatably connected to the outer shell 705, and two limit bars 711 are fixedly connected to the bottom inner surface of the mounting shell 708. Two clamping plates 712 are arranged in the mounting shell 708, and two limit grooves 713 are provided at the bottom and top of the two clamping plates 712. One end of the two clamping plates 712 is sleeved with an arc-shaped rubber sleeve 714, and two third springs 715 are fixedly connected between the two clamping plates 712. A rectangular groove 716 is provided at the center of one of the clamping plates 712, and a conductive spring sheet 717 is installed in the rectangular groove 716. A wire 718 is fixedly connected between the conductive spring sheet 717 and the tester 2. Before the test, the entire outer shell 705 and the internal parts are inserted into the specified position in the mounting seat 605 through the mounting block 701. At this time Under the action of the corresponding second spring 703, multiple positioning beads 704 move inward. When the mounting seat 605 is installed, multiple positioning beads 704 fit with the corresponding positioning arc groove 606 to achieve positioning and fixation. When the pointer 707 is not aligned with the terminal on one side of the filter body 8, the second threaded rod 710 is rotated at this time, so that the second threaded rod 710 rotates to drive the second threaded seat 709 to move, thereby driving the mounting shell 708 to move in the shell 705, and then driving the two clamping plates 712 to move, so that the pointer 707 is aligned with the terminal on one side of the filter body 8, completing fine-tuning, so that the two clamping plates 712 can clamp the terminal on one side of the filter body 8 more accurately, and the conductive spring sheet 717 can fully contact the terminal, so that the test signal can When it is necessary to accurately convey the filter, and when it needs to be connected to the terminal on one side of the filter body 8, the two clamping plates 712 are driven to move toward the terminal on one side of the filter body 8 under the push of the pushing mechanism 6. Since the inner surfaces of the two arc-shaped rubber sleeves 714 are arc-shaped, the terminal on one side of the filter body 8 is inserted between the two arc-shaped rubber sleeves 714. Under the action of the limiting strip 711 and the limiting groove 713, the two arc-shaped rubber sleeves 714 drive the connected clamping plates 712 to open. When the pushing mechanism 6 continues to push, the conductive spring sheet 717 on one of the clamping plates 712 fits with the terminal on one side of the filter body 8. During the test, the test signal is transmitted to the terminal on one side of the filter body 8 through the wire 718 and the conductive spring sheet 717 to realize the test.

In the combined state, the two clamping plates 712 are fitted with the terminals on the filter body 8, and the conductive spring sheet 717 is fitted with the terminals on the filter body 8. When testing the filter body 8, the two clamping plates 712 on one side of the test mechanism 7 clamp the input terminal of the filter body 8, and the two clamping plates 712 on the other side of the test mechanism 7 clamp the output terminal of the filter body 8, so that the test signal is transmitted to the input terminal through the wire 718 and the conductive spring sheet 717, and then enters the filter body 8. After the test, it flows from the output terminal to the tester 2 through the wire 718, completing the entire test process.

[0040] The working principle of this embodiment is as follows: before the test, the staff places multiple filter bodies 8 in the placement groove 11, one of which is close to the baffle 12, and the other two are close to the corresponding fixed frame 3, and the filter body 8 presses the two positioning blocks 404 downward, so that the two positioning blocks 404 squeeze the multiple first springs 403 connected to each other. When the bottom of the filter body 8 is in contact with the bottom end of the placement groove 11, the two positioning blocks 404 clamp the two sides of the filter body 8 under the elastic force of the corresponding first springs 403 to achieve positioning;

[0041] Then rotate the first threaded rod 502 so that the first threaded rod 502 drives the bonding plate 503 to be in close contact with the front end of the filter body 8. Similarly, rotate the remaining first threaded rods 502 to further fix the plurality of filter bodies 8 under the action of the baffle 12 and the fixing frame 3.

[0042] According to the size of the filter body 8, the mounting block 701 is inserted into the specified position in the mounting seat 605, so that the pointer 707 can be aligned with the terminal on one side of the filter body 8 to the maximum extent. At this time, the plurality of positioning beads 704 move inward under the action of the corresponding second spring 703, so that the plurality of positioning beads 704 fit with the corresponding positioning arc groove 606 to achieve positioning and fixing, and then the second threaded rod 710 is rotated so that the second threaded rod 710 rotates to drive the second threaded seat 709 to move, thereby driving the mounting shell 708 to move in the outer shell 705, and then driving the two clamping plates 712 to move, so that the pointer 707 is accurately aligned with the terminal on one side of the filter body 8, and fine-tuning is completed. Similarly, the remaining test mechanisms 7 are adjusted;

[0043] When testing the filter body 8, the two cylinders 604 are started, so that the pistons of the two cylinders 604 push the connected movable seats 602, so that the movable seats 602 drive the connected multiple mounting seats 605 to move, thereby driving the two clamping plates 712 to move toward the terminals on one side of the filter body 8. Since the inner surfaces of the two arc-shaped rubber sleeves 714 are arc-shaped, the terminals on one side of the filter body 8 are inserted between the two arc-shaped rubber sleeves 714. Under the action of the limiting strips 711 and the limiting grooves 713, the two arc-shaped rubber sleeves 714 drive the connected clamping plates 712 to open. When the pushing mechanism 6 continues to push, The conductive spring piece 717 on one of the clamping plates 712 is fitted with the input terminal on one side of the filter body 8. Similarly, the other pushing mechanism 6 is started at the same time to drive the two clamping plates 712 on the connected test mechanism 7 to move, so that the conductive spring piece 717 is fitted with the output terminal on one side of the filter body 8. During the test, the tester 2 is started, so that the test signal is transmitted to the input terminal through the wire 718 and the conductive spring piece 717, and then enters the filter body 8. After the test, it flows from the output terminal to the tester 2 through the wire 718, completing the entire test process, and testing multiple filter bodies 8 at the same time;

[0044] After the test is completed, the pushing mechanism 6 and the clamping mechanism 5 are reset, and the filter body 8 is removed.
