Description
Technical Field
[0001] This application belongs to the field of copper foil performance testing technology, specifically relating to a copper foil flexibility testing system and testing method. Background Technology
[0002] Copper foil is made by hammering copper with a certain proportion of other metals. It is generally available in two types: 90% and 88% copper content, typically 16*16cm. Copper foil is the most widely used decorative material. It has low surface oxygen content, allowing it to adhere to various substrates such as metals and insulating materials, and offers a wide operating temperature range. Its main applications are electromagnetic shielding and antistatic properties. By placing conductive copper foil on a substrate combined with a metal base, it provides excellent conductivity and electromagnetic shielding.
[0003] In the copper foil production process, multiple performance tests are required, among which flexibility testing is a crucial step. Flexibility testing involves bending the copper foil and observing how quickly it recovers its shape. Faster recovery indicates better flexibility than slower recovery. However, existing flexibility testing devices can only test one copper foil at a time, making it inefficient for testing multiple foils simultaneously. Furthermore, testing at different locations is cumbersome, requiring the copper foil to be unsecured and its position adjusted before testing, further reducing efficiency. Summary of the Invention
[0004] The purpose of this application is to provide a copper foil flexibility testing system to solve the problems mentioned in the background art. The existing flexibility testing devices can only test one copper foil at a time, and cannot test multiple copper foils at the same time. The testing efficiency is slow, and the operation is cumbersome when testing at different locations. It is necessary to first release the fixed adjustment of the copper foil position before testing, which also results in low efficiency.
[0005] Another objective of this application is to provide a method for testing the flexibility of copper foil.
[0006] To achieve the above objectives, this application provides the following technical solution:
[0007] A copper foil flexibility testing system includes a base plate. Supports are slidably mounted on both the left and right sides of the upper surface of the base plate. A copper foil insertion plate is fixedly mounted on the support. The copper foil insertion plate has several copper foil insertion holes. A clamping bolt is threaded onto the copper foil insertion plate opposite the insertion holes. Columns are fixedly mounted at the four corners of the upper surface of the base plate. A common mounting frame is fixedly mounted on the top of each of the four columns. A threaded rod is rotatably mounted inside the mounting frame. A motor is fixedly mounted on the side of the mounting frame. The motor's output... A shaft is fixedly connected to a threaded rod. A threaded plate is threaded onto the outer surface of the threaded rod. A cylinder is fixedly mounted on the lower surface of the threaded plate. A test head is fixedly mounted on the piston rod end of the cylinder. A contact plate is fixedly mounted on one end of the test head. The lower surface of the test head is flush with the lower surface of the contact plate. A connecting plate is fixedly mounted on one end of the threaded plate. An mounting plate is fixedly mounted on the end of the connecting plate. A scale is fixedly mounted on the side of the mounting plate. An indicator frame is slidably mounted on the mounting plate. The indicator frame is located directly below the contact plate and works in conjunction with the contact plate.
[0008] The above scheme employs two copper foil insertion plates with multiple copper foil insertion holes, which, when used with clamping bolts, allow for the fixation of multiple copper foils. A cylinder then drives the test head up and down, enabling simultaneous flexibility testing of multiple copper foils. This improves trapezoidal testing efficiency and allows for comparative testing of the flexibility of multiple copper foils. Furthermore, a contact plate, indicator frame, and scale control the downward movement distance of the test head, allowing for flexibility testing under different pressures and enhancing testing versatility. A motor, in conjunction with a threaded rod and threaded plate, drives the threaded rod to rotate, which in turn drives the threaded plate to move left and right, thus moving the test head left and right. This allows for flexibility testing at different locations while the copper foils are fixed, improving versatility.
[0009] In the above scheme, it should be noted that both the motor and the cylinder are electrically connected to an external power source.
[0010] In a preferred embodiment, a plurality of sliding blocks are fixedly installed on the lower surface of the bracket, and a plurality of sliding grooves are formed on the upper surface of the base plate. The sliding blocks are slidably installed on the inner wall of the sliding grooves, and a guide rod is fixedly installed on the inner wall of the sliding grooves. The sliding blocks are slidably installed on the outer surface of the guide rod.
[0011] By adopting the above scheme, the sliding block can slide within the sliding groove to achieve stable sliding of the bracket. The guide rod can serve as a limit to prevent the sliding block from detaching from the sliding groove when the bracket slides.
[0012] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the mounting frame, and a guide groove is provided at the end of the threaded plate, the guide groove and the guide bars being used in conjunction.
[0013] With the above solution, when the threaded rod rotates and drives the threaded plate to move, the threaded plate will slide on the surface of the guide bar through the guide groove, which has good sliding stability and avoids the phenomenon of tilting and shaking of the threaded plate.
[0014] In a preferred embodiment, a plurality of support rods are slidably mounted on the threaded plate, and the bottom end of the support rods is fixedly connected to the upper surface of the test head.
[0015] With the above solution, when the cylinder drives the test head to move up and down, the test head will drive the support rod to move up and down synchronously. The support rod plays a supporting and guiding role, which can prevent the test head from shaking or tilting.
[0016] In a preferred embodiment, a plurality of limiting sleeves are fixedly installed on the side of the mounting plate, and a plurality of limiting rods are fixedly installed between the two columns at the rear position. The limiting sleeves are slidably installed on the outer surface of the limiting rods at the corresponding positions.
[0017] By using the above solution, the sliding of the limiting sleeve on the surface of the limiting rod can support the movement of the mounting plate and improve the stability of the movement.
[0018] In a preferred embodiment, the mounting plate has a slide rail and a guide rod two is fixedly installed on the inner wall of the slide rail. The indicator frame is slidably installed on the inner wall of the slide rail and on the outer surface of the guide rod two. A spring is fixedly installed between the indicator frame and the inner wall of the slide rail.
[0019] Using the above scheme, the guide rod two is used in conjunction with the spring. The guide rod two provides limit support for the up and down movement of the indicator frame, improving the smoothness of the movement. When the indicator frame is touched by the abutment plate and moves downward, the spring will deform. Therefore, when the abutment plate moves upward, the indicator frame will move upward to reset under the elastic force of the spring.
[0020] A method for testing the flexibility of copper foil, wherein the aforementioned copper foil flexibility testing system is used to test the flexibility of the copper foil to be tested;
[0021] It includes the following steps:
[0022] S100, insert the two ends of the copper foil to be tested into the copper foil insertion holes on the two copper foil insertion plates, and screw in the clamping bolts to fix the two ends of the copper foil.
[0023] S200: The starting motor drives the test head to move downward. When the test head moves downward, it will cause the copper foil to bend. When the test head moves, it will drive the contact plate to move. When the contact plate moves to touch the indicator frame, it will drive the indicator frame to move downward. The indicator frame, together with the scale, controls the degree of bending of the copper foil.
[0024] S300, then the cylinder drives the test head to move upward to reset. The copper foil that is restored to its original state first has better flexibility than the copper foil that is restored to its original state later. At the same time, different positions can be tested. Adjust the slide wire motor to start, the motor drives the thread rod to rotate, the thread rod drives the thread plate to move, and the thread plate drives the test head to move horizontally, switching the test position.
[0025] Compared with the prior art, the present invention has the following advantages:
[0026] This copper foil flexibility testing system uses two copper foil insertion plates with multiple copper foil insertion holes, which, together with clamping bolts, can fix multiple copper foils. Then, a cylinder drives the test head to move up and down, enabling simultaneous flexibility testing of multiple copper foils. This improves the efficiency of trapezoidal testing and allows for comparative testing of the flexibility of multiple copper foils. Furthermore, by using a contact plate with an indicator frame and a scale, the downward movement distance of the test head can be controlled, allowing for flexibility testing under different pressures and improving testing versatility.
[0027] This copper foil flexibility testing system uses a motor in conjunction with a threaded rod and a threaded plate. The motor drives the threaded rod to rotate, which in turn drives the threaded plate to move left and right, which in turn drives the test head to move left and right. This allows for flexibility testing at different locations while the copper foil is fixed, thus improving its versatility. Attached Figure Description

[0034] Please see Figure 1-5 This application provides a copper foil flexibility testing system, including a base plate 1. Supports 2 are slidably mounted on both the left and right sides of the upper surface of the base plate 1. A copper foil insertion plate 3 is fixedly mounted on the support 2. The copper foil insertion plate 3 has several copper foil insertion holes. A clamping bolt 4 is threadedly installed on the copper foil insertion plate 3 opposite to the copper foil insertion holes. Columns 5 are fixedly mounted at the four corners of the upper surface of the base plate 1. A common mounting frame 6 is fixedly mounted on the top of each of the four columns 5. A threaded rod 8 is rotatably mounted inside the mounting frame 6. A motor 7 is fixedly mounted on the side of the mounting frame 6, and the output shaft of the motor 7 is fixed to the threaded rod 8. The connection is as follows: a threaded plate 9 is threadedly installed on the outer surface of the threaded rod 8; a cylinder 10 is fixedly installed on the lower surface of the threaded plate 9; a test head 11 is fixedly installed at the end of the piston rod of the cylinder 10; a contact plate 12 is fixedly installed at one end of the test head 11; the lower surface of the test head 11 is flush with the lower surface of the contact plate 12; a connecting plate 13 is fixedly installed at one end of the threaded plate 9; an mounting plate 14 is fixedly installed at the end of the connecting plate 13; a scale 15 is fixedly installed on the side of the mounting plate 14; and an indicator frame 16 is slidably arranged on the mounting plate 14. The indicator frame 16 is located directly below the contact plate 12 and works in conjunction with the contact plate 12.
[0035] By setting two copper foil insertion plates 3, each with multiple copper foil insertion holes and used in conjunction with clamping bolts 4, multiple copper foils can be fixed. Then, in conjunction with cylinder 10, the test head 11 moves up and down, enabling simultaneous flexibility testing of multiple copper foils. This improves trapezoidal testing efficiency and allows for comparative testing of the flexibility of multiple copper foils. Furthermore, using the contact plate 12 in conjunction with the indicator frame 16 and scale 15, the downward movement distance of the test head 11 can be controlled, allowing for flexibility testing under different pressures and increasing testing versatility. By setting a motor 7 in conjunction with a threaded rod 8 and a threaded plate 9, the motor 7 drives the threaded rod 8 to rotate, which in turn drives the threaded plate 9 to move left and right, which in turn drives the test head 11 to move left and right. This allows for flexibility testing at different locations while the copper foil is fixed, improving versatility.
[0036] A plurality of sliding blocks 17 are fixedly installed on the lower surface of the bracket 2, and a plurality of sliding grooves are provided on the upper surface of the base plate 1. The sliding blocks 17 are slidably installed on the inner wall of the sliding groove, and a guide rod 18 is fixedly installed on the inner wall of the sliding groove. The sliding blocks 17 are slidably installed on the outer surface of the guide rod 18. By sliding the sliding blocks 17 in the sliding groove, the bracket 2 can be stably slid. The guide rod 18 can play a limiting role to prevent the sliding blocks 17 from disengaging from the sliding groove when the bracket 2 slides.
[0037] A number of guide bars 19 are fixedly installed on the inner wall of the mounting frame 6. The end of the threaded plate 9 is provided with a guide groove. The guide groove and the guide bar 19 are used in conjunction. When the threaded rod 8 rotates to drive the threaded plate 9 to move, the threaded plate 9 will slide on the surface of the guide bar 19 through the guide groove. The sliding stability is good, and the phenomenon of tilting and shaking of the threaded plate 9 is avoided.
[0038] Several support rods 20 are slidably installed on the threaded plate 9. The bottom end of the support rod 20 is fixedly connected to the upper surface of the test head 11. When the cylinder 10 drives the test head 11 to move up and down, the test head 11 will drive the support rods 20 to move up and down synchronously. The support rods 20 play a supporting and guiding role, which can prevent the test head 11 from shaking or tilting.
[0039] A number of limiting sleeves 22 are fixedly installed on the side of the mounting plate 14, and a number of limiting rods 21 are fixedly installed between the two columns 5 at the rear position. The limiting sleeves 22 are slidably installed on the outer surface of the limiting rods 21 at the corresponding positions. By sliding the limiting sleeves 22 on the surface of the limiting rods 21, the movement of the mounting plate 14 can be supported, and the stability of the movement can be improved.
[0040] The mounting plate 14 has a slide rail, and a guide rod 23 is fixedly installed on the inner wall of the slide rail. The indicator frame 16 is slidably installed on the inner wall of the slide rail and on the outer surface of the guide rod 23. A spring 24 is fixedly installed between the indicator frame 16 and the inner wall of the slide rail. The guide rod 23 works in conjunction with the spring 24 to limit and support the up and down movement of the indicator frame 16, thereby improving the smoothness of the movement. When the indicator frame 16 is touched by the abutment plate 12 and moves downward, the spring 24 will deform. Therefore, when the abutment plate 12 moves upward, the indicator frame 16 will return to its original position under the elastic force of the spring 24.
[0041] In use, the two ends of the copper foil to be tested for flexibility are inserted into the copper foil insertion holes on the two copper foil insertion plates 3. The clamping bolts 4 are screwed in to fix the two ends of the copper foil. Then, the motor 7 is started to drive the test head 11 to move downward. When the test head 11 moves downward, it will drive the copper foil to bend. When the test head 11 moves, it will drive the contact plate 12 to move. When the contact plate 12 moves to touch the indicator frame 16, it will drive the indicator frame 16 to move downward. The indicator frame 16, together with the scale 15, controls the degree of bending of the copper foil. Then, the cylinder 10 drives the test head 11 to move upward to reset. The copper foil that is restored to its original state first has better flexibility than the copper foil that is restored to its original state later. At the same time, different positions can be tested. Adjust the sliding motor 7 to start. The motor 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the threaded plate 9 to move. The threaded plate 9 drives the test head 11 to move horizontally to switch the test position.
