Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Figures 1-6As shown, a high-precision automated soft FPC board bending machine includes a base mechanism 1, which includes a frame 11 and a clamping assembly 12. The bottom side of the clamping assembly 12 is arranged at the inner bottom of the frame 11, and a lifting assembly 2 is arranged on the rear side of the base mechanism 1. The top front end of the lifting assembly 2 is fixedly connected to the side pressure assembly 3, and the top side of the side pressure assembly 3 is movably connected to the upper pressure assembly 4. The front side of the base mechanism 1 is provided with a support body 5, and the top of the support body 5 is fixedly connected to the rotating motor 6.

The inner sides of the side pressure assembly 3 and the upper pressure assembly 4 are in movably contact with the left side of the V-body model 8. A controller 9 is arranged on the upper left side of the front side of the base mechanism 1.

[0023] like Figure 1 and Figure 6 As shown, the clamping assembly 12 includes a support plate 121, a slide rail 122, a clamping plate 123 and a telescopic buckle 124. The clamping plate 123 is located below the side pressure assembly 3, the upper pressure assembly 4 and the V-body mold 8. The bottom side of the slide rail 122 is fixedly connected to the top side of the support plate 121, and the bottom side of the clamping plate 123 is slidably connected to the top side of the slide rail 122. The telescopic buckle 124 is buckled at the front and rear ends of the clamping plate 123. The FPC board is placed on the clamping plate 123 of the clamping assembly 12. The clamping plate 123 can be fine-tuned by sliding the bottom of the clamping plate 123 with the slide rail 122 to better align the bending position. After adjustment, the front and rear ends of the clamping plate 123 are fastened using the telescopic buckle 124 to ensure that the FPC board does not move during the bending process.

[0024] like Figure 1 and Figure 2 As shown, the lifting assembly 2 includes a cylinder 21, a movable column 22 and a gas rod 23. The gas rod 23 is arranged on the inner side of the cylinder 21. The bottom side of the movable column 22 is fixedly connected to the top of the gas rod 23. The top of the movable column 22 is fixedly connected to the rear end of the side pressure assembly 3. The controller 9 controls the operation of the lifting assembly 2. The gas rod 23 in the cylinder 21 begins to extend, pushing the movable column 22 to move upward, and the movable column 22 drives the side pressure assembly 3 to rise as a whole.

[0025] like Figure 1 and Figure 3 As shown, the side pressure assembly 3 includes a connecting member 31, a connecting rod 32 and a pressing member 33. The rear end of the connecting rod 32 is fixedly connected to the axis of the connecting member 31, and the front end of the connecting rod 32 is fixedly connected to the rear end of the pressing member 33. As the side pressure assembly 3 rises, the connecting rod 32 drives the connecting member 31 to move. When the pressing member 33 contacts the FPC board, a certain lateral pressure is applied to the FPC board.

[0026] like Figure 1 and Figure 3 、 Figure 4 As shown, the upper pressure assembly 4 includes a rotating rod 41, an upper pressure piece 42 and an elastic shaft 43. The output end of the rotating motor 6 is fixedly connected to the front end of the rotating rod 41, the rear end of the rotating rod 41 is fixedly connected to the front end of the upper pressure piece 42, the top end of the elastic shaft 43 is fixedly connected to the bottom side of the upper pressure piece 42, and the bottom end of the elastic shaft 43 is fixedly connected to the top side of the side pressure assembly 3. The controller 9 starts the rotating motor 6, and the rotating motor 6 drives the rotating rod 41 of the upper pressure assembly 4 to rotate, and the upper pressure piece 42 connected to the rear end of the rotating rod 41 rotates accordingly;

[0027] Example 2: Figure 1 and Figure 5 As shown, the pushing assembly 7 includes a connecting shell 71, a linear motor 72, a telescopic rod 73 and a support rod 74. The connecting shell 71 is arranged at the leftmost end of the connecting shell 71, and the telescopic rod 73 runs through the interior of the connecting shell 71. The output end of the linear motor 72 is fixedly connected to the left end of the telescopic rod 73, the outer end of the support rod 74 is fixedly connected to the side wall of the telescopic rod 73, and the inner end of the support rod 74 is fixedly connected to the front and rear sides of the V-body phantom 8. The controller 9 controls the operation of the pushing assembly 7, the linear motor 72 drives the telescopic rod 73 to move in the connecting shell 71, and the telescopic rod 73 drives the V-body phantom 8 to move to the left through the support rod 74.

[0028] Working principle: Figures 1-6 As shown, the FPC board is placed on the clamping plate 123 of the clamping assembly 12. The clamping plate 123 can be fine-tuned by sliding the bottom thereof with the slide rail 122 to better align the bending position. After adjustment, the front and rear ends of the clamping plate 123 are fastened with the telescopic buckle 124 to ensure that the FPC board does not move during the bending process.

[0029] After starting the device, the controller 9 initializes the settings of each component;

[0030] During the bending operation, the controller 9 controls the lifting assembly 2 to work, the air rod 23 in the air cylinder 21 begins to extend, pushing the movable column 22 upward, and the movable column 22 drives the side pressure assembly 3 to rise as a whole, so that the lower pressure piece 33 of the side pressure assembly 3 is close to the FPC board;

[0031] As the side pressure assembly 3 rises, its connecting rod 32 drives the connecting piece 31 to move. When the lower pressing piece 33 contacts the FPC board, it applies a certain lateral pressure to the FPC board to prepare for subsequent bending.

[0032] As the side pressure assembly 3 rises and contacts the FPC board, the controller 9 starts the rotary motor 6, which drives the rotating rod 41 of the upper pressure assembly 4 to rotate. The upper pressure piece 42 connected to the rear end of the rotating rod 41 rotates accordingly. During the rotation of the upper pressure piece 42, the elastic shaft 43 on the bottom side thereof elastically expands and contracts according to the shape and force of the FPC board, thereby playing a role in buffering and uniformly applying force.

[0033] After the upper pressing member 42 rotates to a suitable angle, it works together with the lower pressing member 33 of the side pressing assembly 3 to bend the FPC board;

[0034] During the bending process, the controller 9 controls the pushing assembly 7 to work, and the linear motor 72 drives the telescopic rod 73 to move in the connecting shell 71. The telescopic rod 73 drives the V-body phantom 8 to move to the left through the support rod 74.

[0035] As the V-body mold 8 moves, it forms a bending mold space together with the upper pressing piece 42 and the lower pressing piece 33, and the FPC board is bent in this space according to the predetermined shape;

[0036] The operator unfastens the telescopic buckle 124 of the clamping assembly 12 and takes the bent FPC board out of the clamping plate 123 . The operator then proceeds to the next FPC board by bending the board and repeating the above steps.
