[0002] With the rapid development of technology, in electrical components, the application of FPC (flexible printed circuit board) in high-tech products such as smart phones and smart computers has gradually increased. Specifically, FPC is a highly reliable and excellent flexible printed circuit board. FPC has the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0003] In order to make better use of the internal space of the product and optimize the product structure, the FPC circuit board can be bent locally according to requirements. However, due to its flexible characteristics, the bending operation is hindered.

[0053] In the present invention, please refer specifically to Figures 2 - 4 As shown, the jig 5 includes:

[0054] A first base 51. The large turntable 4 is provided with a first notch 41 at a position corresponding to each jig 5. The first base 51 is fixedly arranged in the first notch 41 to limit the first base 51 through the first notch 41. An imitation groove 511 matching the material 200 (i.e., the FPC circuit board) is provided at the upper end of the first base 51 to limit the material 200 (i.e., the FPC circuit board) through the imitation groove 511. At least one pressing long groove 512 is provided at the front end of the first base 51, and the pressing long groove 512 communicates with the side end of the imitation groove 511 to press the material 200 (i.e., the FPC circuit board) from the side end.

[0055] A pressing plate 52 is located in front of the first base 51. A pressing protrusion 521 is provided at a position corresponding to each pressing long groove 512 on the pressing plate 52, and the material 200 (i.e., the FPC circuit board) is pressed by the cooperation of the pressing long groove 512 and the pressing protrusion 521. A smooth shaft jack hole 522 is axially provided on each pressing protrusion 521.

[0056] A movable block 53 is located in front of the pressing plate 52. Linear bearings 54 are axially arranged at both ends of the movable block 53. The middle part of the pressing plate 52 is fixedly connected to the movable block 53, and specifically, the middle part of the pressing plate 52 and the movable block 53 can be fixed together by bolts, screws, etc.

[0057] A second base 55 is fixedly arranged in front of the movable block 53.

[0058] Two smooth shafts 56. A blind hole 513 is provided on each pressing long groove 512. One end of each smooth shaft 56 passes through the smooth shaft jack hole 522 and is buried in the blind hole 513, the middle part passes through one of the linear bearings 54, and the other end is fixed on the second base 55. A spring 57 is sleeved on each smooth shaft 56 between the movable block 53 and the second base 55.

[0059] A cam follower 58 is fixedly provided at the bottom of the movable block 53. In a specific implementation, a follower fixing block 531 is provided at the bottom of the movable block 53, and the cam follower 58 is fixedly provided on the follower fixing block 531.

[0060] When the jig 5 is in use and in a normal state, due to the elastic force of the spring 57, the movable block 53 and the pressing plate 52 will be pushed forward, and the pressing protrusion 521 will be closely attached to the pressing long groove 512. When it is necessary to place the material 200 on the jig 5, the lifting assembly 6 can be used to lift the cam follower 58 upward, so that the movable block 53 and the pressing plate 52 move backward, and then the pressing protrusion 521 leaves the pressing long groove 512. After the material 200 is placed on the profiling groove 511 of the jig 5, the lifting assembly 6 will descend, and the movable block 53 and the pressing plate 52 will move forward and return under the elastic force of the spring 57, so as to press the material 200 in the profiling groove 511.

[0061] In the present invention, please refer with emphasis to Figure 5 and Figure 6 As shown, the lifting assembly 6 includes:

[0062] A lifting cylinder 61, the bottom of the lifting cylinder 61 is fixedly provided on the support table 1. In a specific implementation, the bottom of the lifting cylinder 61 can be fixed on the support table 1 through a cylinder base 611, and the lifting cylinder 61 is electrically connected to the control device 9 to control the operation of the lifting cylinder 61 through the control device 9.

[0063] A lifting fixing plate 62, the lifting fixing plate 62 is fixedly connected to the movable end of the lifting cylinder 61.

[0064] At least one lifting rod 63. The large turntable 4 is provided with a lifting notch 42 at the position corresponding to each cam follower 58. The upper end of the lifting rod 63 has a wedge-shaped structure 631. The lower end of the lifting rod 63 is fixedly connected to the lifting fixing plate 62, and the upper end of the lifting rod 63 passes through the lifting notch 42 and the wedge-shaped structure 631 abuts against the cam follower 58, so as to drive the movable block 53 and the pressing plate 52 to move forward and backward through the lifting cylinder 61. In a specific implementation, the specific number of the lifting rods 63 can be determined according to the number of the jigs 5. For example, when two jigs 5 are arranged adjacent to each other on the large turntable 4, one lifting rod 63 can be provided at each end of the lifting fixing plate 62 to simultaneously lift the cam followers 58 on the two jigs 5.

[0065] When the lifting device 6 is in operation, when the material 200 (i.e., FPC circuit board) needs to be placed on the fixture 5 or removed from the fixture 5, the lifting cylinder 61 is controlled by the control device 9 to link the lifting rod 63 to lift upward. During the lifting process, the wedge-shaped structure 631 pushes the cam follower 58 to roll, so that the pressing protrusion 521 leaves the pressing long groove 512. When the material 200 (i.e., FPC circuit board) needs to be fixed on the fixture 5, the lifting cylinder 61 is controlled by the control device 9 to link the lifting rod 63 to move downward and leave the cam follower 58.

[0066] In the present invention, the end leveling mechanism 8 includes an extension plate 81, a leveling cylinder 82 and a material leveling plate 83. One end of the extension plate 81 is fixed on the small turntable 3, the leveling cylinder 82 is fixed on the bottom of the extension plate 81, and the material leveling plate 83 is fixedly connected to the movable end of the leveling cylinder 82. In a specific implementation, the leveling cylinder 82 is electrically connected to the control device 9, so that the control device 9 controls the leveling cylinder 82 to drive the material leveling plate 83 to move forward and backward, thereby realizing the end leveling operation of the material 200 placed on the jig 5.

[0067] The working principle of the turntable device 100 of the present invention is as follows:

[0068] When the material 200 (i.e., FPC circuit board) needs to be placed on the jig 5 or removed from the jig 5, the control device 9 controls the lifting cylinder 61 to link the lifting rod 63 to lift upward. During the lifting process, the wedge-shaped structure 631 pushes the cam follower 58 to roll, so that the clamping protrusion 521 leaves the clamping slot 512. When the material 200 (i.e., FPC circuit board) needs to be fixed on the jig 5, the control device 9 only needs to control the lifting cylinder 61 to link the lifting rod 63 to descend and leave the cam follower 58.

[0069] After placing the material 200 (i.e., FPC circuit board), the control device 9 controls the cam divider 2 to drive the large turntable 4 to rotate, so as to transfer the material 200 on the jig 5 to the designated station. In specific implementation, each process involved in the entire bending process can be arranged around the turntable device. In this way, during the rotation of the large turntable 4 driven by the cam divider 2, the material 200 can be conveyed to each process for processing, thus well realizing the connection of each process together; during the rotation of the large turntable 5, the in-place detection sensor 7 will perform in-place detection on the material 200 (i.e., FPC circuit board) on the jig 5. And once it detects that the material 200 (i.e., FPC circuit board) has reached the position, the in-place detection sensor 7 will send an in-place signal to the control device 9 for the control device 9 to control other components to perform subsequent operations; at the same time, the control device 9 can control the leveling cylinder 82 to move forward to drive the material leveling plate 83 to level the end of the material 200 (i.e., FPC circuit board) placed on the jig 5. In addition, it should be noted that the implementation procedures for controlling cylinders, cam followers, etc. to work and receiving sensor signals through the control device 9 (such as a PLC controller) are well-known to those skilled in the art and can be obtained without creative labor.

[0070] In summary, the present invention has the following advantages: 1. The large turntable is connected to the moving part of the cam divider, and a plurality of jigs or jig groups are arranged around the large turntable. When working specifically, the cam divider can drive the large turntable and the jigs or jig groups on the large turntable to rotate; therefore, as long as each process is arranged around the turntable device of the present invention, the connection of each process can be well realized, and by the cam divider driving the large turntable to rotate automatically, the material (i.e., FPC circuit board) placed on the jig or jig group can be rotated to the designated station, and the overall operation efficiency is high;

[0071] 2. Through the mutual cooperation of the jig and the lifting part assembly, the automatic loosening or automatic pressing of the material (i.e., FPC circuit board) can be well realized, which helps to improve the degree of automation in production.

[0072] Although the specific implementation manners of the present invention are described above, those skilled in the art should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope protected by the claims of the present invention.
