[0025] See also Figure 1-4, a bending mechanism for a flexible circuit board, comprising a shell 1, a pull-out placement slot 2 is provided inside the shell 1, when in use, the placement slot 2 is pulled out from the shell 1, and during the pulling process, the placement slot 2 slides on the inner wall of the shell 1 through the sliding blocks 3 provided on both sides to assist in pulling, and after being pulled out, the position of the positioning rod 4 is adjusted according to the position where the flexible circuit board needs to be bent. When adjusting, the positioning rod 4 is driven to slide on the slide groove 5 by starting the electric sliders 13 on both sides of the positioning, and the position of the positioning rod 4 requires that the bending part of the flexible circuit board is aligned with the front end of the placement slot 2, and the tail contacts the positioning rod 4 to complete the adjustment of the positioning rod 4, and then the placement slot 2 is pushed into the shell 1 so that the placement slot 2 is against the shaping block 11;

[0026] After the placement slot 2 is in place, a fixing plate 6 is provided at the entire upper end of the placement slot 2. The fixing plate 6 is pushed downward by the electric lifting rod 7 provided at the upper end of the fixing plate 6, pressing most of the flexible circuit board so that it is fixed on the placement slot 2. At this time, a mounting plate 8 is provided at the front end of the fixing plate 6. The mounting plate 8 is pressed downward by the electric push rod 9 also provided at the upper end, thereby driving the lower pressing block 10 to move downward close to the shaping block 11, so that the protruding flexible circuit board is bent and shaped under the pressure of the shaping block 11 and the lower pressing block 10, and the bending is completed. Subsequently, the lower pressing block 10 and the fixing plate 6 are raised to pull out the placement slot 2 to remove the flexible circuit board;

[0027] When bending, the lower pressing block 10 and the shaping block 11 are replaceable. The corresponding angle can be replaced according to the bending angle. Specifically, the shaping block 11 can be replaced by removing the bolts from the lower end after pulling the mounting slot 12 from one side of the shell 1. Similarly, the fixing bolts fixed on the lower pressing block 10 at the openings on both sides of the shell 1 can be removed, and the lower pressing block 10 can be replaced from the mounting plate 8.

[0028] The working principle of the present invention is as follows: as shown in the figure, it comprises a shell 1, and a pull-out placement slot 2 is provided inside the shell 1. When in use, the placement slot 2 is pulled out from the shell 1. During the pulling-out process, the placement slot 2 slides on the inner wall of the shell 1 through the sliding blocks 3 provided on both sides to assist in pulling. After being pulled out, the position of the positioning rod 4 is adjusted according to the position where the flexible circuit board needs to be bent. When adjusting, the positioning rod 4 is driven to slide on the slide slot 5 by starting the electric sliders 13 on both sides of the positioning. The position of the positioning rod 4 requires that the bending part of the flexible circuit board be aligned with the front end of the placement slot 2. The tail contacts the positioning rod 4 to complete the adjustment of the positioning rod 4. Then, the placement slot 2 is pushed into the inside of the shell 1 so that the placement slot 2 is against the shaping block 11.

[0029] After the placement slot 2 is in place, a fixing plate 6 is provided at the entire upper end of the placement slot 2. The fixing plate 6 is pushed downward by the electric lifting rod 7 provided at the upper end of the fixing plate 6, pressing most of the flexible circuit board so that it is fixed on the placement slot 2. At this time, a mounting plate 8 is provided at the front end of the fixing plate 6. The mounting plate 8 is pressed downward by the electric push rod 9 also provided at the upper end, thereby driving the lower pressing block 10 to move downward close to the shaping block 11, so that the protruding flexible circuit board is bent and shaped under the pressure of the shaping block 11 and the lower pressing block 10, and the bending is completed. Subsequently, the lower pressing block 10 and the fixing plate 6 are raised to pull out the placement slot 2 to remove the flexible circuit board;

[0030] When bending, the lower pressing block 10 and the shaping block 11 are replaceable. The corresponding angle can be replaced according to the bending angle. Specifically, the shaping block 11 can be replaced by removing the bolts from the lower end after pulling the mounting slot 12 from one side of the shell 1. Similarly, the fixing bolts fixed on the lower pressing block 10 at the openings on both sides of the shell 1 can be removed, and the lower pressing block 10 can be replaced from the mounting plate 8.
