Some existing tensile testers require manual clamping of the flexible circuit board, which is a cumbersome and inefficient operation. Manual clamping can easily cause the flexible circuit board to be tested to tilt, resulting in tears at the edges of the flexible circuit board during stretching, affecting the accuracy of the test.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a flexible circuit board stretching device for a tension detector is provided, in order to achieve a purpose with greater practical value. Utility Model Content

Some existing tension detectors require manual clamping of the flexible circuit board, which is a cumbersome operation process and low in efficiency. In addition, manual clamping can easily cause the flexible circuit board to be tested to be skewed, resulting in the edge of the flexible circuit board being easily torn during stretching, affecting the detection accuracy.

[0015] Furthermore, a plurality of rollers are installed on the bottom end surfaces of the movable shell and the supporting body, and the rollers are slidably installed in the track.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] Through the coordinated use of the threaded rod, rail, movable shell, supporting mechanism, rectangular shell and clamp assembly, when the flexible circuit board to be tested is placed on the supporting mechanism, the threaded rod is rotated by starting the driving motor, thereby driving the movable shell to move in the direction of the rectangular shell, and through the cooperation of the push block on the side wall of the movable shell, the supporting mechanism is pushed in the direction of the rectangular shell during the movement of the movable shell until the side wall of the supporting body of the supporting mechanism rests against the side wall of the mounting block.

The supporting body remains perpendicular to the clamp assemblies on both sides, thereby ensuring that the flexible circuit board to be tested is in a vertical state when clamped by the clamp assemblies on both sides, thereby obtaining more accurate tensile test values.

[0032] Through the coordinated use of the threaded rod 8, the track 5, the movable shell 10, the supporting mechanism, the rectangular shell 11 and the clamp assembly, when the flexible circuit board to be tested is placed on the supporting mechanism, the threaded rod 8 is rotated by starting the driving motor 9, thereby driving the movable shell 10 to move toward the rectangular shell 11, and through the cooperation of the push block 31 on the side wall of the movable shell 10, the supporting mechanism is pushed to move toward the rectangular shell 11 during the movement of the movable shell 10 until the side wall of the supporting body 19 of the supporting mechanism rests against the side wall of the mounting block 7. At this time, the two ends of the flexible circuit board to be tested are between the clamping plates 15 of the clamping assembly, and the flexible circuit board to be tested is clamped by the clamping assembly, and then the driving motor 9 rotates the threaded rod 8 in the opposite direction, thereby moving the movable shell 10 toward the driving motor 9, thereby achieving the stretching of the flexible circuit board to be tested.

After completing the tensile test of the flexible circuit board to be inspected, the clamp assembly is reset, and the supporting body 19 is reset by the action of the spring 27. Several supporting platforms of different sizes are formed by several steps 21 in the trapezoidal groove 20, so as to adapt to flexible circuit boards to be inspected of various widths.

[0043] The specific usage and function of this embodiment are as follows:

Then the staff starts the drive motor 9 to move the housing 10 to drive the clamp assembly to move toward the rectangular housing 11, and pushes the supporting mechanism to move toward the rectangular housing 11 through the push block 31 on the side wall of the mobile housing 10 until the side wall of the supporting body 19 of the supporting mechanism touches the side wall of the mounting block 7. At this time, the two ends of the flexible circuit board to be tested are between the clamping plates 15 of the clamping assembly, and the staff The operator starts micro motor 12 and micro motor 2 13 to rotate the screw rod 18, thereby displacing a pair of clamps 15 in relative directions to complete the clamping of the flexible circuit board to be tested, and then drives the motor 9 to rotate the threaded rod 8 in the opposite direction, thereby moving the movable housing 10 toward the drive motor 9 to stretch the flexible circuit board to be tested.
