Detailed Implementation

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: As Figures 1-3 As shown, an FFC wire bending detection device includes an electrical control box 1, with a platform 2 connected to the top of the electrical control box 1; a drive device is connected inside the electrical control box 1, and the drive device is driven to drive a drive rod 3, which is located above the platform 2; a slide table 4 is slidably fitted on the platform 2, and the drive rod 3 drives the slide table 4 to move linearly; a movable plate 5 is connected to the slide table 4, and a fixed plate 6 is connected to the platform 2, with the fixed plate 6 parallel to the movable plate 5 and a gap between the fixed plate 6 and the movable plate 5.

[0025] A support plate 7 is connected to the platform 2. The driving device is a motor 8. The motor 8 is connected to the power input end of the reducer 9. The reducer 9 is connected to the bottom end of the support plate 7, and the reducer 9 and the motor 8 are housed in the electrical control box 1.

[0026] The power output shaft of the reducer 9 passes through the support plate 7, and the drive rod 3 is connected to the power output shaft of the reducer 9. One end of the drive rod 3 is rotatably connected to the connecting rod 10, and one end of the connecting rod 10 is rotatably connected to the push-pull rod 11.

[0027] The push-pull rod 11 is slidably fitted to the slide block 12, and the slide block 12 is connected to the support plate 7; one end of the slide table 4 is connected to the fixed seat 13, and one end of the push-pull rod 11 is connected to the fixed seat 13.

[0028] A linear guide rail 14 is connected to the platform 2, a slide table 4 is connected to the slider of the linear guide rail 14, and a movable plate 5 is vertically connected to the slide table 4.

[0029] The fixed plate 6 is vertically connected to the platform 2. Both the fixed plate 6 and the movable plate 5 are made of nylon.

[0030] The bottom of the electrical control box 1 is connected to an adjustable support foot 15, and the top of one end of the platform 2 is connected to a support leg 16.

[0031] The electrical control box 1 contains a controller, and the motor 8 is electrically connected to the controller.

[0032] A speed controller 17 for adjusting the speed of motor 8 is connected to the outside of the electrical control box 1. The speed controller 17 is electrically connected to the controller.

[0033] Example 2: This example is a further improvement on Example 1. The main improvement is that, in Example 1, the operator could not record how many times the FFC wire 20 was bent before breakage; while in this example, the above defect can be avoided. Specifically: It also includes a counting system, which includes an infrared probe 18 and a counter 19. One end of the support plate 7 is connected to an ear plate, the infrared probe 18 is connected to the ear plate, and the drive rod 3 passes above the infrared probe 18. The counter 19 is connected to the outside of the electrical control box 1, and the counter 19 and the infrared probe 18 are electrically connected to the controller. In this embodiment, the counting system can accurately record the number of bends of the FFC wire 20, which can effectively assist operators in judging the quality of the FFC wire 20.

[0034] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0035] The specific working principle of this utility model is as follows: After purchasing 20 tons of FFC wire, the wire harness manufacturer randomly selects samples for testing. For example... Figure 4 As shown, the operator cuts a section of FFC wire 20, uses tape to attach one end of the FFC wire 20 to the inner side of the fixed plate 6, bends the FFC wire 20 into an S-shape, and attaches the other end to the inner side of the movable plate 5. After the motor 8 starts, the drive rod 3 rotates, and the drive rod 3 drives the push-pull rod 11 to move back and forth. The push-pull rod 11 pulls the movable plate 5 to move back and forth, thereby simulating the frequent bending process of the FFC wire 20. When the rotating rod passes above the infrared probe 18, the counter 19 will record one time, indicating that the FFC wire 20 has been bent once. When the FFC wire 20 is bent to the specified number of times without any damage, it proves that the batch of FFC wire 20 is qualified. Conversely, if the FFC wire 20 is damaged, it indicates that it is unqualified.

[0036] This invention can help companies test the bending life of FFC wire 20, thereby avoiding economic losses for the company.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
