This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Please refer to Figure 1-10 An FPC bending device 100 is provided, including an adsorption component and a bending component 30.

[0032] The bending assembly 30 includes a support frame 31, a movable cylinder 32 disposed on the support frame 31, a support plate 33 disposed on the output end of the movable cylinder 32, and a pressing cylinder 34 disposed on the support frame 31. A rotary cylinder is provided on the support plate 33, which is not shown in the figure. The output end of the rotary cylinder is provided with a turntable 311, on which a plurality of mounting protrusions 3111 for placing FPC201 are provided. The moving cylinder 32 is used to drive the mounting protrusions 3111 to move to correspond with the adsorption head 11. The rotary cylinder is used to drive the corresponding mounting protrusions 3111 on the turntable 311 to correspond with the adsorption head 11. The output end of the pressing cylinder 34 is provided with a pressing plate 341, which is used to drive the pressing plate 341 to press against the FPC201 on the mounting protrusions 3111. The support frame 31 is provided with a bending module, which corresponds to the mounting protrusions 3111 and is used to bend the FPC201.

[0033] Furthermore, the bending module includes a bending cylinder 35 and a bending cylinder 36. The output end of bending cylinder 35 is equipped with a lower pressure plate 351, and the output end of bending cylinder 36 is equipped with a lower pressure plate 361. The output directions of bending cylinders 35 and 36 are opposite. Both bending cylinders 35 and 36 correspond to the mounting protrusion 3111. Bending cylinders 35 and 36 are used to bend the FPC201 in two directions. The mounting protrusion 3111 is equipped with a positioning post 3112, which is compatible with the mounting hole 2011 on the FPC201. The positioning post 3112 facilitates the alignment of the portion of the FPC201 to be bent with the lower pressure plate 351 or the lower pressure plate 361, thereby facilitating the bending of the FPC201.

[0034] Specifically, in this embodiment, four sets of mounting protrusions 3111 are symmetrically distributed on the turntable 311, each set including multiple mounting protrusions 3111. The pressure plate 341 is provided with several pressure protrusions 3411 corresponding to the mounting protrusions 3111. The number of pressure protrusions 3411, lower pressure plate one 351, and lower pressure plate two 361 corresponds to the number of mounting protrusions 3111 in each set, thereby enabling the simultaneous bending of multiple FPC201s and improving the bending efficiency of FPC201. The output end of bending cylinder one 35 is positioned downwards in the thickness direction of FPC201, and the output end of bending cylinder two 36 is positioned upwards in the thickness direction of FPC201.

[0035] When bending FPC201, firstly, the corresponding mounting protrusion 3111 is rotated by a rotary cylinder to align with either the first pressure plate 351 or the second pressure plate 361, so that the part of FPC201 to be bent aligns with the first pressure plate 351 or the second pressure plate 361, and the remaining part of FPC201 aligns with the pressing protrusion 3411. Then, the pressing cylinder 34 is activated, driving the pressing protrusion 3411 to descend and press against the FPC201 on the mounting protrusion 3111. Then, the bending cylinder 35 or the bending cylinder 36 is activated, and the first pressure plate 351 or the second pressure plate 361 applies pressure to bend the part of FPC201. By setting up bending cylinder 35 and bending cylinder 36 with opposite directions, when bending FPC201, they cooperate with pressing cylinder 34 to achieve bending of FPC201 in two directions, thereby realizing multi-directional bending of FPC201 and improving the practicality of FPC bending equipment 100.

[0036] Furthermore, the FPC bending equipment 100 also includes a conveying module 40, which is used to convey the FPC 201 to a position opposite to the suction head 11.

[0037] The adsorption assembly includes a moving module 10 and an adsorption module 20 disposed on the output end of the moving module 10. The moving module 10 drives the adsorption module 20 to transfer the FPC 201 from the conveying module 40 to the mounting protrusion 3111.

The output end of the lifting motor 22 is provided with a first synchronous pulley set 24. The output end of the first synchronous pulley set 24 is provided with a mounting frame 25. The mounting frame 25 is slidably disposed on the slide rail 211. The mounting frame 25 is provided with a pneumatic component 26, a rotating rod 27 communicating with the pneumatic component 26, and an elastic connecting assembly 28 disposed between the rotating rod 27 and the adsorption head 11. The adsorption head 11 and the rotating rod 27 are interconnected. The rotating rod 27 and the pneumatic component 26 are rotatably connected. The rotating rod 27 is provided with a connecting hole 271 communicating with the pneumatic component 26. The adsorption head 11 is provided with a plurality of adsorption holes 111 communicating with the connecting hole 271. The lifting motor 22 is used to drive the adsorption head 11 to press down and adsorb the FPC 201. Furthermore, in this embodiment, the pneumatic component 26 is a vacuum generator. The pneumatic component 26 is not fully shown in the figure. The rotating rod 27 and the pneumatic component 26 are connected via a rotary joint.

[0039] Furthermore, the first synchronous pulley set 24 includes a first drive gear 241, a first driven gear 242, and a first drive belt 243.

The mounting bracket 25 is fixedly connected to the first drive belt 243. Specifically, in this embodiment, the first drive gear 241 and the second drive gear 291 are arranged sequentially along the thickness direction of the FPC201.

[0040] Furthermore, the rotating rod 27 is provided with a mounting groove 272 that communicates with the connecting hole 271. The elastic connection assembly 28 includes a connecting rod 281, a telescopic spring 282 sleeved on the connecting rod 281, and a support sleeve 283 fixedly connected to the adsorption head 11. One end of the connecting rod 281 is connected to the support sleeve 283, and the other end of the connecting rod 281 is slidably disposed in the mounting groove 272. One end of the telescopic spring 282 is fixedly connected to the support sleeve 283, and the other end of the telescopic spring 282 is fixedly connected to the rotating rod 27.

The groove wall of the placement groove 2831 is provided with a limiting groove 2832. The limiting rod 2811 is slidably disposed in the limiting groove 2832. The limiting rod 2811 and the limiting groove 2832 cooperate to limit the sliding range of the connecting rod 281. Specifically, in this embodiment, both the connecting rod 281 and the limiting rod 2811 are hollow rods, and both the connecting rod 281 and the limiting rod 2811 are connected to the connecting hole 271 on the rotating rod 27 and the adsorption hole 111 on the adsorption head 11.

[0042] During adsorption, the lifting motor 22 controls the mounting frame 25 to descend via the first synchronous pulley set 24 until the adsorption head 11 contacts the FPC201, and then presses down, compressing the telescopic spring 282. The two ends of the connecting rod 281 slide in the mounting groove 272 and the placement groove 2831 respectively. The telescopic spring 282 applies a reverse elastic force to the rotating rod 27, thereby reducing the impact of the pressure applied by the adsorption head 11 to the FPC201 to prevent damage to the FPC201.

The output end of the second synchronous pulley set 29 and at least one rotating rod 27 are coaxially fixed.
