Description

Technical Field

[0001] The invention relates to the field of detection technology, and in particular to a filter continuous detection tool. Background Art

[0002] A filter is an electronic device or circuit that selectively passes or suppresses signal components within a specific frequency range from an input signal. Filters are widely used in many fields such as electronic engineering, communications, and audio processing. Single-ended input / output filters generally include a metal or plastic housing that contains circuit boards, capacitors, inductors and other components. There is a terminal at each end of the housing for connecting input and output signals.

[0003] The filter needs to be tested before leaving the factory. When testing the plug-in filter, the output of the signal generator needs to be connected to the input of the filter; the CH1 probe of the oscilloscope needs to be connected to the output of the signal generator to measure the input signal; the CH2 probe of the oscilloscope needs to be connected to the output of the filter (i.e. one end of capacitor C) to measure the output signal. Make sure that the ground terminals of all devices are connected together to form a unified ground wire. Then adjust the frequency of the signal generator and observe the input and output signals on the oscilloscope. Check whether the cutoff frequency of the filter is as expected and complete the filter test.

[0004] Currently, when testing filters, matching molds are usually required for positioning. However, each size of filter corresponds to a mold, which increases the cost of mold manufacturing. During testing, continuous batch testing is not possible. The filter inside the mold must be taken out before the next filter can be placed in the mold, resulting in low detection efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a filter continuous detection tool to solve the technical problems in the prior art that the filter detection tool cannot be tested continuously in batches, has low detection efficiency and high cost.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A filter continuous detection tool, comprising:

[0008] A chain conveyor belt, used for conveying filters, wherein a plurality of baffles are evenly distributed on the chain conveyor belt;

[0009] Conveying tracks, the number of which is set to two, and the two conveying tracks are respectively arranged on both sides of the chain conveyor belt;

[0010] The number of the test components is set to two, and the two test components are respectively arranged on two conveying tracks;

[0011] The chain conveyor moves intermittently, driving the baffle to push the filter inside it, so that the terminals at both ends of the filter are connected to the test components on both sides of the chain conveyor respectively, completing the detection of the filter, and as the chain conveyor is transported, the baffle is used to separate the tested filter from the test component, and the next filter to be measured is connected to the test component to achieve continuous detection.

[0012] Furthermore, the conveying track includes two upper and lower limit plates arranged in parallel, a moving space is formed between the two limit plates, and rotating rollers are rotatably installed on opposite sides of the two limit plates.

[0013] Furthermore, the test component includes two clamping plates, which are symmetrically arranged inside the moving space, and the middle part of the clamping plate protrudes toward one side of the limiting plate so that the clamping plate is away from the side of the limiting plate to form a limiting groove, and a detection probe is arranged inside the limiting groove, and the probe is connected to a detection wire;

[0014] Among them, after the terminal on the filter moves to the moving space, it reaches the inside of the limit groove under the guidance of the clamping plate and is connected to the detection probe to complete the detection of the filter.

[0015] Furthermore, the clamping plate is configured to be in an arc shape that bulges toward a side away from the limiting plate, and the clamping plate is elastic and deforms when being squeezed.

[0016] Furthermore, a sliding rod is fixedly connected to one side of the clamping plate close to the limiting plate, and the sliding rod passes through the limiting plate and is slidably connected to the limiting plate. A first spring is fixedly connected between the clamping plate and the limiting plate. When the terminal on the filter moves to one side of the clamping plate, the clamping plate is squeezed to move toward the side of the limiting plate, and the first spring is compressed and has a rebound force, thereby adjusting the distance between the two clamping plates and ensuring that the two clamping plates are always in contact with the terminals on the filter.

[0017] Furthermore, a connecting rod is fixedly connected between the detection probe and the detection wire, the connecting rod is slidably connected to the limit plate, a fixing plate is provided on the side of the limit plate away from the clamping plate, the fixing plate is fixedly connected to the connecting rod, and a second spring is fixedly connected between the fixing plate and the limit plate;

[0018] When the terminal on the filter moves into the limiting groove, it squeezes the detection probe, causing the connecting rod to drive the fixing plate to move away from the limiting plate. At the same time, the spring has a rebound force, so that the detection probe is always in contact with the terminal inside the limiting groove.

[0019] Furthermore, guide plates are provided on both sides of the chain conveyor belt, and the guide plates are fixedly connected to any one of the limit plates on the same side thereof, and along the transmission direction of the chain conveyor belt, the distance between the two guide plates becomes smaller and smaller.

[0020] Furthermore, the chain conveyor includes a frame, both sides of the frame are fixedly connected with horizontally arranged transverse plates, the top of the transverse plates is connected with vertically arranged vertical plates, and the limiting plates are connected to the vertical plates.

[0021] Furthermore, the two limit plates on the conveying track are respectively fixed at different heights of the vertical plate, and the distance between the two limit plates and the height of the moving space relative to the chain conveyor are adjusted;

[0022] The vertical plate is fixed at different horizontal positions of the horizontal plate, thereby adjusting the distance between the two conveying tracks.

[0023] Furthermore, a push plate is provided on one side of the chain conveyor belt, and the push plate is controlled by a hydraulic rod to move in a direction perpendicular to the chain conveyor belt. When an unqualified filter is detected, the hydraulic rod controls the push plate to move, thereby removing the unqualified filter.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention uses a chain conveyor to intermittently convey the filter, and limits the terminals on the filter through a conveying track. Then, a test component is connected to the terminal for testing. As the chain conveyor moves intermittently, a baffle drives the filter to contact and separate from the test component, thereby realizing continuous automatic detection. Continuous batch detection is possible without preparing multiple molds, and the detection efficiency is high and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, the present invention provides a filter continuous detection tool, comprising:

[0035] A chain conveyor belt 1 is used to convey filters, and a plurality of baffles 2 are evenly distributed on the chain conveyor belt 1;

[0036] Conveying tracks 3, the number of which is set to two, and the two conveying tracks 3 are respectively arranged on both sides of the chain conveyor belt 1;

[0037] The number of the test components 4 is set to two, and the two test components 4 are respectively arranged on the two conveying tracks 3;

[0038] Among them, the chain conveyor 1 moves intermittently, driving the baffle 2 to push the filter inside it, so that the terminals at both ends of the filter are connected to the test components 4 on both sides of the chain conveyor 1 respectively, to complete the detection of the filter, and as the chain conveyor 1 is transported, the baffle 2 is used to separate the tested filter from the test component 4, and the next filter to be measured is connected to the test component 4 to achieve continuous detection.

[0039] At present, when testing filters specifically, matching molds are usually required for limiting. However, each size of filter corresponds to a mold, which increases the mold manufacturing cost. In addition, continuous batch testing is not possible during testing. The filter inside the mold must be taken out before the next filter can be placed in the mold. The detection efficiency is low. Therefore, it is necessary to develop a continuous filter detection tooling.

[0040] In this embodiment, a chain conveyor 1 is provided to intermittently convey the filter, and the terminals on the filter are limited by a conveying track 3. Then, a test component 4 is connected to the terminals for testing. As the chain conveyor 1 moves intermittently, the baffle 2 drives the filter to contact and separate from the test component 4, thereby realizing continuous automatic detection. Continuous batch detection is possible without preparing multiple molds, and the detection efficiency is high and the cost is low.

[0041] In actual use, 1. Place the filters to be tested flat on the chain conveyor 1 one by one, and only place one filter between the two baffles 2;

[0042] 2. The chain conveyor 1 moves intermittently, pushing the filter inside it to move through the baffle 2, and making the filter inside it contact with the test component 4 for testing;

[0043] 3. As the chain conveyor 1 moves, the baffle 2 pushes the tested filter to continue moving, thereby separating the tested filter from the test component 4.

[0044] As a preferred embodiment of this embodiment, the conveying track 3 includes two upper and lower parallel limit plates 5, a moving space 6 is formed between the two limit plates 5, and a rotating roller 7 is rotatably installed on opposite sides of the two limit plates 5. As the chain conveyor 1 moves, the terminals on both sides of the filter move into the moving space 6, and the limit plates 5 limit the terminals.

[0045] The specific structure of the test component 4 is described in detail below. Figure 3 and Figure 4 As shown, the test component 4 includes two clamping plates 8, which are symmetrically arranged inside the moving space 6. The middle part of the clamping plates 8 protrudes toward the side of the limiting plate 5 so that the clamping plates 8 are away from the side of the limiting plate 5 to form a limiting groove 9. A detection probe 10 is arranged inside the limiting groove 9, and the probe is connected to a detection wire 11;

[0046] After the terminal on the filter moves to the moving space 6, it reaches the inside of the limiting groove 9 under the guidance of the clamping plate 8 and is connected to the detection probe 10, thereby completing the detection of the filter.

[0047] The terminal inside the moving space 6 reaches the inside of the limiting groove 9 as the chain conveyor 1 moves. Since the terminal is generally cylindrical, the terminal can better fit with the limiting groove 9 and contact with the detection probe 10, thereby realizing the detection of the filter.

[0048] If the clamping plate 8 is set to be linear, it is difficult for the terminal inside the moving space 6 to enter between the clamping plates 8, and it is even more difficult to enter the limiting groove 9, so it is difficult to achieve the connection between the detection probe 10 and the terminal. In order to solve this problem, the clamping plate 8 is set to be an arc that bulges away from the limiting plate 5, and the clamping plate 8 is elastic, and the clamping plate 8 is deformed when squeezed. Through the guidance of the arc clamping plate 8, it is convenient for the terminal to enter the limiting groove 9. The clamping plate 8 is elastic and can be adjusted accordingly according to the size of the terminal, so that the terminal can enter the limiting groove 9.

[0049] In order to ensure that the clamping plate 8 can always be in contact with the terminal, a sliding rod 12 is fixedly connected to the side of the clamping plate 8 close to the limiting plate 5. The sliding rod 12 passes through the limiting plate 5 and is slidably connected to the limiting plate 5. A first spring 13 is fixedly connected between the clamping plate 8 and the limiting plate 5. When the terminal on the filter moves to one side of the clamping plate 8, the clamping plate 8 is squeezed to move toward the limiting plate 5, and the first spring 13 is compressed and has a rebound force, thereby adjusting the distance between the two clamping plates 8 and ensuring that the two clamping plates 8 are always in contact with the terminals on the filter.

[0050] By providing the first spring 13 and the rebound force of the first spring 13 , when the terminal enters between the two clamping plates 8 , the clamping plates 8 tend to move toward the terminal, so that the clamping plates 8 are always in contact with the terminal on the filter.

[0051] In order to make the terminal contact with the detection probe 10 and prevent the terminal from being out of contact, a connecting rod 14 is fixedly connected between the detection probe 10 and the detection wire 11, and the connecting rod 14 is slidably connected to the limit plate 5. A fixing plate 15 is provided on the side of the limit plate 5 away from the clamping plate 8, and the fixing plate 15 is fixedly connected to the connecting rod 14. A second spring 16 is fixedly connected between the fixing plate 15 and the limit plate 5;

[0052] When the terminal on the filter moves into the limiting groove 9, it squeezes the detection probe 10, so that the connecting rod 14 drives the fixing plate 15 to move away from the limiting plate 5. At the same time, the spring has a rebound force, so that the detection probe 10 is always in contact with the terminal inside the limiting groove 9.

[0053] The detection probe 10 can move up and down inside the limiting groove 9. By providing a second spring 16, under the action of the rebound force of the second spring 16, when the terminal enters the limiting groove 9, the detection probe 10 tends to move toward the terminal, so that the detection probe 10 is always in contact with the terminal inside the limiting groove 9.

[0054] In order to make the filter centered on the chain conveyor 1 and make the terminals on both sides of the filter contact with the corresponding test components 4, as shown in FIG. Figure 1 and Figure 2As shown, guide plates 17 are provided on both sides of the chain conveyor 1, and the guide plates 17 are fixedly connected to any one of the limit plates 5 on the same side thereof. Along the transmission direction of the chain conveyor 1, the distance between the two guide plates 17 becomes smaller and smaller.

[0055] After the filter on the chain conveyor 1 passes through the two guide plates 17 , it will gradually be centered so that the distances between the terminals on both sides and the test component 4 are equal.

[0056] There are many filter sizes, and the corresponding terminal sizes are also many. In order to make the device suitable for filters of different sizes, such as Figure 2 and Figure 3 As shown, the chain conveyor 1 includes a frame 18 , and horizontally arranged transverse plates 19 are fixedly connected on both sides of the frame 18 . A vertically arranged vertical plate 20 is connected to the top of the transverse plate 19 , and the limiting plate 5 is connected to the vertical plate 20 .

[0057] The two limit plates 5 on the conveying track 3 are respectively fixed at different heights of the vertical plate 20, and the distance between the two limit plates 5 and the height of the moving space 6 relative to the chain conveyor belt 1 are adjusted;

[0058] The vertical plate 20 is fixed at different horizontal positions of the horizontal plate 19 to adjust the distance between the two conveying rails 3.

[0059] By providing the transverse plate 19 and the vertical plate 20 , the distance between the two limit plates 5 and the height of the moving space 6 relative to the chain conveyor 1 can be adjusted by adjusting the fixed position of the limit plate 5 on the vertical plate 20 .

[0060] By adjusting the fixing position of the vertical plate 20 on the horizontal plate 19 , the distance between the two conveying rails 3 is adjusted.

[0061] A push plate 21 is provided on one side of the chain conveyor 1. The push plate 21 is controlled by a hydraulic rod 22 to move in a direction perpendicular to the chain conveyor 1. When an unqualified filter is detected, the hydraulic rod 22 controls the push plate 21 to move, thereby removing the unqualified filter. When an unqualified filter is detected, the unqualified filter can be removed by the hydraulic rod 22 and the push plate 21, realizing automatic detection.

[0062] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
