Preferably, the angle between the support frame 4 and the horizontal plane is an acute angle, that is, the support frame 4 is installed at an angle, which is convenient for laying and conveying the flexible circuit board 5. A front rotating shaft 6 and a front roller shaft 7 are installed side by side in sequence at the front end of the support frame 4, and two axially movable limiting rings 600 are symmetrically sleeved on the front rotating shaft 6, which can be adjusted according to the width of the flexible circuit board 5 to adapt to flexible circuit boards 5 of different specifications.

[0026] When in use, after the flexible circuit board 5 comes out of the assembly line, the flexible circuit board 5 first goes from the top outer wall of the front shaft 6 to the bottom outer wall of the front roller shaft 7, then passes through the top plane of the flat plate 10, goes from the top outer wall of the rear shaft 8 to the bottom outer wall of the rear roller shaft 9, and then transitions from the top outer wall of the first shaft 111 to the top outer walls of the two rubber cylinder shafts 122, and finally the end of the flexible circuit board 5 is wound and fixed on the receiving drum 130 on the winding shaft 13, and the winding motor 14 rotates to drive the winding shaft 13, that is, the receiving drum 130 to rotate synchronously, and then the flexible circuit board 5 is wound on the receiving drum 130, and the receiving drum 130 is a detachable sleeve fixed On the reel 13, the whole roll of flexible circuit board 5 can be removed by removing the material collection cylinder 130, and then another material collection cylinder 130 can be installed to continue collecting materials; the limit ring 600 installed on the front rotating shaft 6 and the positioning ring 112 installed on the first rotating shaft 111 can be movably fixed on both sides of the flexible circuit board 5, so that it can be adjusted according to the width of the flexible circuit board 5 to adapt to flexible circuit boards 5 of different specifications, and can limit the deviation of the flexible circuit board 5 after swinging left and right; when the fine-tuning motor 120 rotates, it drives the seat plate 121 and the two rubber cylinder shafts 122 to rotate the angle, so that the position of the flexible circuit board 5 can be adjusted. This application can prevent the flexible circuit board 5 from becoming loose or swinging left and right after arching up and down, and can also adjust the angle of the flexible circuit board 5, which is easy to use.

[0027] In some embodiments, the rear ends of the two L-shaped fixing seats 3 are fixedly connected to the frame 1 by screws, and the front ends of the two fixing seats 3 are connected and fixed by nuts 301 after passing through the support frame 4 through a bolt 300; the support frame 4 can swing along the bolt 300 to change the angle between the support frame 4 and the horizontal plane, so as to facilitate the support and transportation of the flexible circuit board 5. By locking the nuts 301 at both ends of the bolt 300, the support frame 4, the fixing seat 3 and the bolt 300 can be fastened together to prevent the support frame 4 from swinging.

[0028] In some embodiments, a screw hole that passes through the inner ring is radially opened on the outer wall of the limit ring 600 and the positioning ring 112, and a threaded component 601 is screwed into the screw hole. The threaded component 601 can be a screw or a screw. When the threaded component 601 is screwed in, the lower end of the threaded component 601 can eventually be fixed against the outer wall of the front rotating shaft 6 or the first rotating shaft 111.
