Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1-8, the embodiment provides a double-flexible-circuit-board display screen bending apparatus, which includes two bending modules symmetrically arranged left and right, where the bending modules include a base 2, a bending part 1, and a display screen seat 31. The display screen seat 31 is slidably connected to the base 2, and the bending member 1 is disposed at one end of the base 2. The bending module comprises a base 11, a servo motor 13, a support arm 12 and a pressure plate 15. The base 11 is fixed in the one end of base 2, and on servo motor 13 was fixed in base 11, servo motor 13's output and support arm 12 were connected, and clamp plate 15 is fixed in the upper end of support arm 12 through the cylinder.
When the circuit board is bent, the display screen and the flexible circuit board are placed on the display screen seat 31, and the display screen seat 31 with the display screen 4 slides to the tail end of the base 2 along the base 2 to reach the bending part 1. The air cylinder in the bending member 1 carries the pressure plate 15 down. The pressure plate 15 is lowered onto the display screen 4 and pressed onto the flexible circuit board of the display screen 4, whereupon the servomotor 13 is activated and the servomotor 13 rotates the support arm 12. The supporting arm 12 rotates, the pressing plate 15 on the supporting arm 12 drives one of the flexible circuit boards on the display screen to bend, and the flexible circuit board bends and bends to the display screen to finish the bending of the display screen 4 once. When bending, the display screen seat 31 will also move correspondingly, so that the flexible circuit board can be bent more precisely. After the bending is completed, the pressing plate 15 is separated from the display 4 by the movement of the display holder 31, and then the display 4 of the flexible circuit board with the bent side of the display holder 31 is separated from the bending part 1. The automatic carrying mechanism takes the display with the bent flexible circuit board on one side onto the display screen seat 31 of the other bending module, the bending module on the other side repeats the previous bending step to bend the other flexible circuit board of the display screen, and after the bending is finished on the other side, the double flexible circuit boards of the display screen are bent. Because the single bending module adopts the scheme that the single supporting arm 12 is bent, when one flexible circuit board is bent, the other flexible circuit board is not influenced, so that the other flexible circuit board does not need to be turned down due to influence, the time for additionally processing the other flexible circuit board is saved, and the bending efficiency of the flexible circuit board is improved. Meanwhile, the single flexible circuit board is bent by the corresponding bending module, so that the bending of the flexible circuit board can be in place, and a better bending effect can be obtained.

By adopting the fixing mode, the display screen 4 is more convenient to take and place, and the bending efficiency of the display screen 4 is improved.
Specifically, a speed reducer 14 is connected between the output end of the servo motor 13 and the support arm 12. The speed reducer 14 reduces the speed of the servo motor 13 of the driving motor 64, and simultaneously improves the output torque, so that the rotating speed of the servo motor 13 is not too high to cause circuit board damage when the supporting arm 12 is driven to rotate by the servo motor 13, and meanwhile, the rotating angle of the supporting arm 12 can be better adjusted through the speed reduction of the speed reducer 14.
Specifically, a stopper 21 for preventing the display screen seat 31 from slipping out is fixed on the base 2. When the display screen seat 31 slides on the base 2, the limiting block 21 can prevent the display screen seat 31 from sliding out of the base 2 too fast.
