Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board testing technology, specifically to a flexible circuit board tensile testing device. Background Technology

[0002] Flexible circuit boards are lightweight, thin, and bendable printed circuit boards. Their substrates are mostly polyimide or polyester film, and they are also known as flexible circuit boards or flexographic circuit boards. Due to their small size and the ability to be quickly installed and connected, they are widely used in electronic devices. In the testing process of flexible circuit boards, it is necessary to test their tensile properties to ensure that the flexible circuit boards have sufficient strength for normal use.

[0003] Existing flexible circuit board tensile testing devices can only perform horizontal tensile testing on flexible circuit boards, resulting in low strength. They cannot change the direction of tension or allow the circuit boards to swing, thus failing to simulate the tensile performance of flexible circuit boards under different usage environments. Therefore, it is necessary to address the limitation of existing flexible circuit board tensile testing devices in changing the direction of tension and allowing the circuit boards to swing, in order to simulate the tensile performance of flexible circuit boards under different usage environments. Utility Model Content

[0004] In view of the problems existing in the current flexible circuit board tensile testing device, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a tensile testing device for flexible circuit boards, which solves the problem that existing tensile testing devices for flexible circuit boards cannot change the direction of the pull or swing to test the flexible circuit board, so as to simulate the tensile performance of the flexible circuit board under different usage environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tensile testing device for flexible circuit boards includes a base, a support plate fixedly connected to the top of the base, a curved slide rail slidably connected to a first support slide rod at one end of the side wall of the support plate, a linear slide rail slidably connected to a second support slide rod at the other end of the side wall of the support plate, clamping plates fixedly connected to the other ends of both the first and second support slide rods via clamping mechanisms, a hydraulic cylinder fixedly connected to the top of the base, a sliding chamber fixedly connected to one end of the hydraulic cylinder, a slide rod fixedly connected inside the sliding chamber, a sliding sleeve slidably connected to the wall of the slide rod, a sliding opening opened on the side wall of the sliding chamber, one end of the first support slide rod passing through the sliding opening and fixedly connected to the side wall of the sliding sleeve, a drive chamber fixedly connected to the other side wall of the base, a drive mechanism fixedly connected to the second support slide rod inside the drive chamber, and a control display terminal fixedly connected to the top of the base.

[0008] Preferably, the clamping mechanism includes a U-shaped support plate and a first cylinder. The first cylinder is fixedly connected to the side wall of the U-shaped support plate, and one end of the first cylinder passes through the side wall of the U-shaped support plate and is fixedly connected to the side wall of the clamping plate.

[0009] Preferably, the driving mechanism includes a second cylinder and a connecting plate. The second cylinder is fixedly connected inside the cavity of the driving chamber. One end of the second cylinder is fixedly connected to the connecting plate. The side wall of the connecting plate is fixedly connected to one end of the second support slide rod.

[0010] Preferably, washers are slidably connected to both ends of the slide rod wall, and springs are sleeved on both ends of the slide rod wall. The two ends of the springs are fixedly connected to the corresponding washers and the inner sidewall of the sliding chamber.

[0011] Furthermore, rubber damping pads are fixedly connected to the corresponding side walls of the U-shaped support plates and clamps at both ends.

[0012] Preferably, the bottom of the base is fixedly connected to multiple casters.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model utilizes a first support slide rod set in a curved slide rail. When the first support slide rod moves upward in the curved slide rail, the sliding sleeve at the other end of the first support slide rod will slide left and right along with the slide rod, thereby realizing that the first support slide rod moves left and right while rising in the curved slide rail, causing the circuit board clamped at one end to swing, so as to realize tensile testing at different angles.

[0015] 2. This utility model utilizes a second cylinder installed in the drive chamber to repeatedly push the connecting plate to move, thereby driving the second support slide rod on the side wall of the connecting plate to move back and forth in the linear slide rail, thus enhancing the test strength of the circuit board.

[0016] 3. This utility model utilizes a first cylinder installed on the side wall of a U-shaped support plate to push a clamping plate to move within the inner wall of the U-shaped support plate, thereby clamping and fixing the circuit board against the inner wall of the U-shaped support plate.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a tensile testing device for flexible circuit boards.

[0026] This utility model provides, for example Figure 1-4The flexible circuit board tensile testing device shown includes a base 1, a support plate 2 fixedly connected to the top of the base 1, a curved slide rail 3 provided at one end of the side wall of the support plate 2 and slidably connected to a first support slide rod 4, a linear slide rail 5 provided at the other end of the side wall of the support plate 2 and slidably connected to a second support slide rod 6, the other ends of the first support slide rod 4 and the second support slide rod 6 are both fixedly connected to clamping plates 7 by clamping mechanisms, a hydraulic cylinder 8 fixedly connected to one end of the top of the base 1, a sliding chamber 9 fixedly connected to one end of the hydraulic cylinder 8, a slide rod 10 fixedly connected inside the cavity of the sliding chamber 9, a sliding sleeve 11 slidably connected to the rod wall of the slide rod 10, a sliding opening 12 provided on the side wall of the sliding chamber 9, one end of the first support slide rod 4 passing through the sliding opening 12 and fixedly connected to the side wall of the sliding sleeve 11, a drive chamber 13 fixedly connected to the other side wall of the base 1, a drive mechanism fixedly connected to the second support slide rod 6 inside the cavity of the drive chamber 13, and the top of the base 1... One end of the circuit board is fixedly connected to a control display terminal 14. The clamping mechanism at both ends drives the clamping plate 7 to clamp the circuit board. The hydraulic cylinder 8 drives the sliding chamber 9 to move upward, thereby driving the first support slide rod 4 to move in the curved slide rail 3. When the first support slide rod 4 moves upward in the curved slide rail 3, the sliding sleeve 11 at the other end of the first support slide rod 4 will slide left and right along the slide rod 10. This allows the first support slide rod 4 to move left and right while rising in the curved slide rail 3, causing the circuit board clamped at one end to swing, realizing tensile testing at different angles. The drive mechanism in the drive chamber 13 drives the second support slide rod 6 to move back and forth in the linear slide rail 5, strengthening the test strength of the circuit board. This solves the problem that existing flexible circuit board tensile testing devices cannot change the direction of tension and swing to test flexible circuit boards, thus simulating the tensile performance of flexible circuit boards under different usage environments.

[0027] To achieve the clamping function, such as Figure 1 As shown, the clamping mechanism includes a U-shaped support plate 15 and a first cylinder 16. The first cylinder 16 is fixedly connected to the side wall of the U-shaped support plate 15. One end of the first cylinder 16 passes through the side wall of the U-shaped support plate 15 and is fixedly connected to the side wall of the clamping plate 7. The first cylinder 16 is used to push the clamping plate 7 to move in the inner side wall of the U-shaped support plate 15. The clamping plate 7 holds the circuit board against the inner side wall of the U-shaped support plate 15, thereby clamping and fixing the circuit board.

[0028] In order to move the second support slide rod 6 back and forth in the linear slide rail 5, such as Figure 1-3As shown, the drive mechanism includes a second cylinder 17 and a connecting plate 18. The second cylinder 17 is fixedly connected inside the cavity of the drive chamber 13. One end of the second cylinder 17 is fixedly connected to the connecting plate 18. The side wall of the connecting plate 18 is fixedly connected to one end of the second support slide rod 6. By repeatedly pushing the connecting plate 18 with the second cylinder 17, the second support slide rod 6 on the side wall of the connecting plate 18 is driven to move back and forth in the linear slide rail 5.

[0029] To prevent the sleeve 11 at one end of the first support slide rod 4 from jamming when it slides to the side, such as Figure 4 As shown, washers 19 are slidably connected to both ends of the slide rod 10, and springs 20 are sleeved on both ends of the slide rod 10. The two ends of the springs 20 are fixedly connected to the corresponding washers 19 and the inner sidewall of the sliding chamber 9. By using the springs 20 and washers 19 at both ends, the sliding sleeve 11 at one end of the first support slide rod 4 is prevented from getting stuck when it slides to the side. It can be quickly reset by the elasticity of the springs 20.

[0030] To increase frictional damping during clamping, such as Figure 1 and 3 As shown, rubber damping pads 21 are fixedly connected to the corresponding side walls of the U-shaped support plates 15 and clamping plates 7 at both ends. By using the rubber damping pads 21, frictional damping is increased during clamping, thus preventing the circuit board from slipping off.

[0031] To facilitate the movement of the device, such as Figure 1-3 As shown, the bottom of the base 1 is fixedly connected with multiple casters 22, which facilitates the movement of the device to other work areas.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
