Description

Technical Field

[0001] The present invention relates to the technical field of durability performance testing, and in particular to a conductive film anti-bending durability testing device and method. Background Art

[0002] PC conductive film is a thin film with conductive properties, usually made of polycarbonate material, and through a special process to make its surface or interior have conductive properties. This film is often used in the electronics, optoelectronics and other industries, especially in applications that require electrostatic protection or conductive connections. Some applications require the conductive film to be bent multiple times, and its anti-bending durability is required to be high. Therefore, before the conductive film is put into use in this application, its anti-bending durability needs to be tested.

[0003] The existing test uses a bending test machine, which clamps the two ends of the conductive film, and then drives the lower end of the conductive film to rotate around a single point through the rotation of the bottom rotor, so as to perform a bending durability test. This test method is inefficient, and the bottom rotor swings eccentrically, which will produce vibration under the action of centrifugal force, affecting the accuracy of the test. Therefore, the announcement number CN221976649U discloses an automobile wiring harness bending durability tester, which includes two symmetrically arranged rotating plates, and a test wire is connected to the two rotating plates through a plurality of wire hoops. The two ends of the test wire are respectively connected to an external detector through a detection harness;

[0004] Each of the rotating plates is connected to a rotating assembly for a bending detection test, a spring for shock absorption is arranged under the two rotating plates, the two rotating plates are rotatably connected and fixed via a rotating shaft, the rotating assembly includes two cylinders, the two cylinders are respectively connected to an air source via an air pipe, a pulley block is connected to the movable end of each cylinder, a plurality of slide rail blocks are connected to the bottom of the pulley block, the pulley block is rotatably connected to a rotating plate, and the other end of the rotating plate is connected to the bottom of the rotating plate via a hinge.

[0005] The above-mentioned bending durability tester uses a cylinder, a pulley group and a push rod to push the turn plate to bend, thereby realizing bending detection. The slide rail connected to the pulley group at the bottom can make the pulley group move stably, thereby improving the stability of the detection. A spring is arranged under the turn plate, which is aligned with the force-bearing area of ​​the front part of the wire harness turn plate to provide damping and shock absorption effect for the wire harness bending plate, thereby improving the accuracy of bending detection and facilitating use.

[0006] However, the above-mentioned bending durability tester can only test the bending durability performance of one point in the middle during the bending test. If you want to obtain more accurate durability performance data, you need to conduct multiple tests, and the location of each test is different. This will seriously affect the test efficiency. At the same time, it is impossible to change the tension of the tested material, the test accuracy is poor, and the data obtained cannot well reflect the durability performance of the material.

[0007] Therefore, a new conductive film anti-bending durability testing device and method can be used to solve the shortcomings of the prior art. Summary of the invention

[0024] The present invention also provides a conductive film anti-bending durability testing method, comprising the conductive film anti-bending durability testing device, and further comprising the following steps:

[0025] S1. First, the conductive film is cut into a rectangle of a specific size, and the periphery of the conductive film is trimmed to make the conductive film regular, and the conductive film is cleaned to remove dust and other attachments on the surface of the conductive film;

[0026] S2. Then, the processed conductive film is horizontally inserted between the two clamping components. The clamping components are controlled by the control panel to fix the two ends of the conductive film. The reserved length of the conductive film to be clamped needs to be more than two centimeters. The clamping force is controlled to prevent the clamping position of the conductive film from exceeding the normal deformation amount to ensure the normal integrity of the clamping part. Then, the distance between the two clamping components is adjusted by moving the components to tighten the conductive film, and the spacing is adjusted to change the tension of the conductive film.

[0027] S3, after the conductive film is tightened, the position of the pressing component is adjusted by the sliding component, so that the two pressing components are pressed against the middle of the conductive film to clamp the middle of the conductive film, and the clamping force is adjusted;

[0028] S4. After steps S1, S2, and S3 are completed, the control panel is used to drive the sliding component and the moving component to operate synchronously. The two moving components operate synchronously in opposite directions. When the two moving components approach each other, the sliding component will drive the middle part of the conductive film to move to a position away from the horizontal line of the clamping component, and move up and down intermittently. When the moving components move away from each other, the sliding component will drive the middle part of the conductive film to move to a position close to the horizontal line of the clamping component, so that the conductive film is in a V shape or an inverted V shape. At this time, the middle part of the conductive film will bend, and the two positions of the conductive film located at the clamping component will also bend. At the same time, the three parts of the conductive film are subjected to a bending durability test.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. When conducting the bending resistance test of the conductive film, the anti-bending durability testing device performs a three-point bending test on the conductive film by setting two clamping components and two pressing components. Testing three points at the same time can effectively improve the test efficiency. At the same time, the local tension of the conductive film can be changed during the test to conduct multi-tension tests. The test results are more representative and can better illustrate the anti-bending performance of the conductive film.

[0031] 2. When conducting the conductive film anti-bending test, the anti-bending durability testing device can eliminate the influence of the gap between the tooth plate and the gear by setting up a transmission structure, ensure that the gear and the tooth plate are tightly bonded, improve the transmission response speed between the gear and the tooth plate, improve the transmission stability, avoid the situation where the conductive film tension changes due to transmission delays, and make the conductive film bending test more accurate.

[0032] 3. When conducting the conductive film anti-bending test, the present anti-bending durability testing device can ensure that the first tooth plate is always meshed with the first gear, and the second tooth plate is always meshed with the second gear by setting an adjusting component and a clamping component, and utilizes the centrifugal force generated by the rotation of the second gear as the rotation thrust of the screw to ensure that the screw always remains in a rotatable state. Once a wear gap appears between the tooth plate and the gear due to long-term use, the gap can be compensated at the first time to improve the transmission efficiency and thereby improve the accuracy of the test.

[0033] In summary, the present invention improves the test efficiency by performing three-point bending tests on the conductive film at the same time, and during the test, ensures that the tension of the conductive film is constant, and can also perform multi-tension tests to improve the accuracy of the test. In addition, the centrifugal force generated by the rotation of the second gear is used to compensate for the gap caused by friction and wear, so that the second tooth plate and the second gear are kept in a tight meshing state, and the response speed of the gear tooth plate transmission is improved, thereby ensuring the stability of the tension of the conductive film, thereby improving the accuracy of the test, and the test results are more representative and can better illustrate the anti-bending performance of the conductive film.

DETAILED DESCRIPTION

[0052] 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.

[0053] Example 1: Reference Figure 1-Figure 3 , Figure 6-Figure 16 , a conductive film anti-bending durability testing device, comprising a body 1, and a control panel 2 fixedly mounted on the body 1;

[0054] A clamping test part, installed on the machine body 1, used to clamp and fix the two ends of the conductive film and perform a bending durability test on both sides of the conductive film. The clamping test part includes two moving components 6 fixedly installed on the machine body 1;

[0055] The moving component 6 includes a slide rail 15 fixedly installed on the body 1, a slider 16 is slidably installed on the slide rail 15, and a linkage mechanism is installed between the two sliders 16; when one of the sliders 16 slides on the corresponding slide rail 15, it will drive the other slider 16 to move on the corresponding slide rail 15 through the linkage mechanism, and the moving directions of the two sliders 16 are opposite and the moving speeds are the same.

[0056] The linkage mechanism includes a first tooth plate 19 and a second tooth plate 20 slidably mounted on the body 1. A second electric push rod 8 is fixedly mounted on the body 1. The telescopic end of the second electric push rod 8 is fixedly connected to the first tooth plate 19. The first tooth plate 19 and the second tooth plate 20 are connected via a transmission structure 21.

[0057] The extension of the telescopic end of the second electric push rod 8 will drive the first tooth plate 19 to move toward the side close to the second tooth plate 20. Under the action of the transmission structure 21, the second tooth plate 20 will be driven to move toward the side close to the first tooth plate 19, thereby causing the two sliders 16 to move toward each other. Conversely, the telescopic end of the second electric push rod 8 is shortened, and the two sliders 16 move away from each other.

[0058] The transmission structure 21 includes a rotating shaft 22 rotatably mounted on the body 1, a first gear 23 is fixedly mounted on the rotating shaft 22, a rotating shaft is rotatably mounted on the first gear 23, a second gear 24 is fixedly mounted on the rotating shaft, and a plurality of adjustment components are installed between the first gear 23 and the second gear 24.

[0059] The movement of the first toothed plate 19 drives the first gear 23 to rotate. The rotation of the first gear 23 drives the second gear 24 to rotate in the same direction and speed as the first gear 23 through multiple adjustment components, thereby driving the second toothed plate 20 to move in the opposite direction to the first toothed plate 19 at the same speed.

[0060] After long-term use, wear will occur between the second tooth plate 20 and the second gear 24, and between the first tooth plate 19 and the first gear 23. After wear, a gap will be generated between the gear (the first gear 23 and the second gear 24) and the tooth plate (the first tooth plate 19 and the second tooth plate 20). The generation of the gap will cause a certain meshing delay when the gear is reversed, which will cause the end of the conductive film to move delayed, while the middle part moves normally, which will increase the tension of the conductive film. Therefore, it is necessary to compensate for the wear gap and take the following measures;

[0061] The adjusting component includes a pressing block 27 rotatably mounted on the second gear 24, a pressing member 32 is installed between the pressing block 27 and the second gear 24, a screw 25 is fixedly mounted on the pressing block 27, a nut 26 is threadedly rotatably mounted on the screw 25, a sliding block is fixedly mounted on the nut 26, and a sliding groove matching the sliding block is provided on the first gear 23;

[0062] The width of the sliding block is smaller than the width of the sliding groove, so that the sliding block can move with the screw 25. Once a wear gap occurs, the first gear 23 and the second gear 24 will be misaligned. At this time, the screw 25 will drive the nut 26 and the first gear 23 to be misaligned. Therefore, the sliding block needs to move laterally in the sliding groove. Since the wear gap is small, generally within one millimeter, the sliding groove can still limit the sliding block to prevent the sliding block from rotating.

[0063] A first disc 28 is fixedly mounted on the nut 26 , a second disc 29 is fixedly mounted on the first disc 28 via a plurality of pillars, a first wedge block 30 is fixedly mounted on the second disc 29 , and a second wedge block 31 matched with the first wedge block 30 is fixedly mounted on the first gear 23 .

[0064] Under the action of the clamping member 32, the screw rod 25 will always remain in a state of being able to rotate at any time. Once a wear gap appears between the tooth plates, the screw rod 25 will rotate, which will drive the nut 26 to move in the first gear 23. The movement of the nut 26 will drive the first disc 28 to move, and the second disc 29 will move through the support. The second disc 29 will drive the first wedge block 30 to move to the side close to the second wedge block 31 and resist the second wedge block 31. Since the second wedge block 31 and the mating side of the second wedge block 31 are inclined, the second wedge block 31 will move under the pressure force, and the movement of the second wedge block 31 will drive the first gear 23 to rotate around the rotating shaft 22, thereby causing the first gear 23 and the second gear 24 to be misaligned.

[0065] The pressing member 32 comprises an arc-shaped cylinder body 34 fixedly mounted on the second gear 24, a first piston disc 36 and a second piston disc 39 are slidably mounted in the arc-shaped cylinder body 34, a push rod 33 is fixedly mounted on the first piston disc 36, and the push rod 33 is fixedly connected to the pressing block 27;

[0066] A one-way tube 42 is fixedly installed on the second piston disc 39, a hollow plate 38 is fixedly installed inside the arc-shaped cylinder body 34, a first spring 37 is fixedly installed between the hollow plate 38 and the first piston disc 36, and a second spring 41 is fixedly installed between the hollow plate 38 and the second piston disc 39, an arc-shaped telescopic rod 40 is fixedly installed on the second piston disc 39, and a steel ball 35 is fixedly installed on the telescopic end of the telescopic rod 40.

[0067] The telescopic end of the telescopic rod 40 can be adjusted in length and locked to ensure that the extension line of the line connecting the top of the steel ball 35 and the telescopic end of the telescopic rod 40 passes through the center point of the arc-shaped cylinder body 34, so that the centrifugal force generated by the steel ball 35 is the largest. As the second gear 24 rotates, the steel ball 35 will drive the second piston disc 39 to move through the telescopic rod 40 under the action of centrifugal force, so that the second piston disc 39 moves toward the port of the arc-shaped cylinder body 34. At this time, the outside air is sucked into the arc-shaped cylinder body 34 through the one-way tube 42. Once the second gear 24 reverses, the second piston disc 39 will be reset under the action of the second spring 41, and the inhaled air will be compressed. The air compression pushes the first piston disc 36 to move close to the corresponding port, and the push rod 33 pushes the pressure block 27 to rotate around its central axis, thereby driving the screw 25 to rotate.

[0068] When the second gear 24 stops rotating, the first spring 37 (the first spring 37 is always in a compressed state) is used to push the push rod 33 to move, and the push rod 33 pushes the pressing block 27 to rotate around its central axis, thereby driving the screw rod 25 to rotate.

[0069] Because the pressure between the second gear 24 and the second tooth plate 20 suddenly increases when the second gear 24 reverses, it is necessary to compensate for the pressure of the first spring 37 by increasing the pressure, thereby increasing the response speed of the screw 25 and improving the tightness of the meshing between the second gear 24 and the second tooth plate 20.

[0070] A clamping assembly 4 is installed on each of the two moving assemblies 6. The moving assembly 6 is used to drive the clamping assembly 4 to move, perform a bending test, and adjust the tension of the conductive film.

[0071] The clamping assembly 4 comprises a clamping driver 17 fixedly mounted on a slide block 16 , and two clamping plates 18 cooperating with each other are slidably mounted on the clamping driver 17 .

[0072] The clamping driver 17 is an existing electrical device, which can realize the movement of the two clamps 18 through the control panel 2, so as to clamp the conductive film. The clamping driver 17 is provided with a sensor, which can be used to detect the clamping force of the clamps 18 and control the deformation of the clamping part of the conductive film to ensure that the deformation is within the standard range. Once the deformation exceeds the standard range, the clamping part will break first due to the excessive deformation, and the data obtained from the test cannot represent the bending resistance and durability of the conductive film.

[0073] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 5 , a pressure test part, mounted on the machine body 1, for performing a bending durability test on the middle part of the conductive film, the pressure test part comprising a sliding assembly 5 fixedly mounted on the machine body 1;

[0074] The sliding assembly 5 includes a track 43 fixedly mounted on the body 1, a first sliding plate 9 and a second sliding plate 10 are slidably mounted on the track 43, a first electric push rod 7 is fixedly mounted on the body 1, and a telescopic end of the first electric push rod 7 is fixedly connected to the first sliding plate 9;

[0075] A screw rod 13 is rotatably mounted on the first sliding plate 9 , a threaded sleeve rotatably connected to the screw rod 13 is fixedly mounted on the second sliding plate 10 , a square servo motor 14 is fixedly mounted on the top of the first sliding plate 9 , and a driving end of the square servo motor 14 is fixedly connected to the screw rod 13 .

[0076] After the two ends of the conductive film are clamped and fixed, the first sliding plate 9 is driven to move by the first electric push rod 7, so that the pressing component 3 on the first sliding plate 9 presses against the upper surface of the conductive film, and then the square servo motor 14 drives the screw rod 13 to rotate, and the second sliding plate 10 is driven to move upward under the action of the threaded sleeve, so that the pressing component 3 on the second sliding plate 10 presses against the lower surface of the conductive film.

[0077] During the test, the first electric push rod 7 and the second electric push rod 8 are started simultaneously through the control panel 2. When the two clamping components 4 are close to each other, the first electric push rod 7 will drive the first sliding plate 9 and the second sliding plate 10 to move, thereby driving the two pressing components 3 to move simultaneously (intermittent reciprocating movement up and down), so the bending resistance durability of three points of the conductive film can be tested at the same time.

[0078] Two pressing assemblies 3 are installed on the sliding assembly 5. The sliding assembly 5 drives the two pressing assemblies 3 to move to perform a bending durability test. The pressing assemblies 3 are used to adjust the tension in the middle of the conductive film.

[0079] The pressing assembly 3 includes a frame, and the two frames are fixedly connected to the first sliding plate 9 and the second sliding plate 10 respectively. A pressure sensor 12 is fixedly mounted on the frame, and a pressing plate 11 is fixedly mounted on the pressure sensor 12.

[0080] As the first sliding plate 9 and the second sliding plate 10 approach each other, the two abutment plates 11 clamp the middle part of the conductive film, and the pressure between the abutment plates 11 and the conductive film is controlled by the pressure sensor 12 to control the deformation of the conductive film, which is consistent with the function of the above-mentioned sensor.

[0081] The specific operation steps of this device are as follows:

[0082] First, the conductive film is cut into a rectangle of a specific size, and the periphery of the conductive film is trimmed to make the conductive film regular, and the conductive film is cleaned to remove dust and other attachments on the surface of the conductive film;

[0083] Then, the processed conductive film is horizontally inserted between the two clamping components 4, and the clamping components 4 are controlled by the control panel 2 to fix the two ends of the conductive film. The reserved length of the conductive film to be clamped needs to be more than two centimeters, and the clamping force is controlled to prevent the clamping position of the conductive film from exceeding the normal deformation amount, ensuring the normal integrity of the clamping part, and then the distance between the two clamping components 4 is adjusted by the moving component 6 to tighten the conductive film, and the spacing is adjusted to change the tension of the conductive film;

[0084] After the conductive film is tightened, the position of the pressing component 3 is adjusted by the sliding component 5, so that the two pressing components 3 are pressed against the middle of the conductive film to clamp the middle of the conductive film, and the clamping force is adjusted;

[0085] After the above steps are completed, the control panel 2 is used to drive the sliding component 5 and the moving component 6 to operate synchronously, and the two moving components 6 operate synchronously in opposite directions. When the two moving components 6 are close to each other, the sliding component 5 will drive the middle part of the conductive film to move to a position away from the horizontal line of the clamping component 4, and move intermittently up and down. When the moving components 6 move in a direction away from each other, the sliding component 5 will drive the middle part of the conductive film to move to a position close to the horizontal line of the clamping component 4, so that the conductive film is in a V shape or an inverted V shape. At this time, the middle position of the conductive film will bend, and the two positions of the conductive film located at the clamping component 4 will also bend. At the same time, the three parts of the conductive film are subjected to a bending durability test.

[0086] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
