[0016] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figures 1 to 7 This utility model discloses an automatic positioning device for a flexible circuit board punching machine, including a frame 10, a stacking platform 20, an automatic adjustment mechanism 30, a first gripping mechanism 40, and a second gripping mechanism 50.

[0019] A stacking platform 20 is mounted on the frame 10 and is configured to stack flexible circuit boards. An automatic positioning mechanism 30 is mounted on the frame 10 and is configured to adjust the position of the flexible circuit boards so that they can be accurately placed at the cutting station. A first gripping mechanism 40 is mounted on the frame 10 and is configured to grip the flexible circuit boards on the stacking platform 20 and place them on the automatic positioning mechanism 30. A second gripping mechanism 50 is mounted on the frame 10 and is configured to grip the flexible circuit boards on the automatic positioning mechanism 30 and place them at the cutting station.

[0020] Understandably, by setting up the stacking platform 20, the automatic positioning mechanism 30, the first gripping mechanism 40, and the second gripping mechanism 50 on the frame 10, the automatic feeding, positioning, and transfer of flexible circuit boards are achieved, improving production efficiency. The stacking platform 20 is used to centrally stack flexible circuit boards for easy batch processing; the automatic positioning mechanism 30 can precisely adjust the position of the flexible circuit boards to ensure the accuracy of subsequent cutting; the first gripping mechanism 40 and the second gripping mechanism 50 are respectively responsible for gripping and placing the boards from the stacking platform 20 to the automatic positioning mechanism 30 and from the automatic positioning mechanism 30 to the cutting station, realizing automated assembly line operation, reducing manual intervention, and lowering labor intensity.

[0021] Reference Figures 5 to 7 The automatic adjustment mechanism 30 includes a first slide rail 31, a first sliding member 32, a support frame 33, a second slide rail 34, a second sliding member 35, an adjustment platform 36, a detection component 37, a first drive component 38, and a second drive component 39. The first slide rail 31 is mounted on the frame 10 and extends along the X-axis. The first sliding member 32 is slidably mounted on the first slide rail 31 along the X-axis. There are multiple first sliding members 32, and these members are connected to the support frame 33. The sliding members 32 slide along the first slide rail 31, which can drive the support frame 33 to slide along the X-axis. The second slide rail 34 is mounted on the support frame 33 and extends along the Y-axis. The second sliding member 35 is slidably mounted on the second slide rail 34 along the Y-axis. The adjustment platform 36... The platform 36 is connected to the second sliding member 35. There are two sets of second slide rails 34, which are spaced apart along the X-axis. There are at least four second sliding members 35, with at least two sliding members 35 slidably disposed on each second slide rail 34. The detection component 37 is disposed on the frame 10 and located directly above the Z-axis of the adjustment platform 36. The detection component 37 is configured to detect the deviation between the positioning hole and the set position on the flexible circuit board. The first drive component 38 connects the frame 10 and the support frame 33. The first drive component 38 is configured to push the support frame 33 to slide along the X-axis. The second drive component 39 connects the second sliding member 35 and the support frame 33. The second drive component 39 is configured to push the second sliding member 35 to slide along the Y-axis.

[0022] Understandably, the automatic positioning mechanism 30 achieves the movement of the support frame 33 along the X-axis direction via the first slide rail 31 and the first sliding member 32, and the movement of the positioning platform 36 along the Y-axis direction via the second slide rail 34 and the second sliding member 35, thereby realizing the precise positioning of the flexible circuit board in the horizontal plane. The use of two sets of second slide rails 34 and at least four second sliding members 35 improves the stability and load-bearing capacity of the positioning platform 36. The detection component 37 can detect the deviation between the positioning holes on the flexible circuit board and the set positions in real time, providing feedback information for automatic positioning. The first drive component 38 and the second drive component 39 drive the movement in the X-axis and Y-axis directions respectively, ensuring the accuracy and efficiency of positioning.

[0023] In this embodiment of the invention, after the first gripping mechanism 40 grips the flexible circuit board from the stacking platform and places it on the positioning platform 36, the detection component 37 begins to capture and compare the difference between the positioning hole on the flexible circuit board and the set position. Subsequently, the position of the positioning platform 36 is adjusted by the first driving component 38 and the second driving component 39 so that the positioning hole on the flexible circuit board is in the set position. Then, the second gripping mechanism 50 grips the flexible circuit board on the positioning platform 36 and places it on the cutting station. In this embodiment, the gripping position of the second gripping mechanism 50 is fixed, and the position of the detection component 37 is fixed.

[0024] Reference Figure 8 The second sliding member 35 is provided with a third sliding rail 351, which extends along the X-axis. A third sliding block 352 is slidably connected to the third sliding rail 351. The third sliding block 352 is rotatably connected to the adjustment platform 36. There are two sets of second drive components 39, which are located at the ends of the two second sliding rails 34 in the extension direction. A second sliding member 35 on the second sliding rail 34 is connected to the second drive component 39. The two sets of second drive components 39 operate independently to drive the adjustment platform 36 to rotate along the horizontal plane.

[0025] It is worth noting that when the flexible circuit board has not only positional deviation but also angular deviation, the two sets of second drive components 39 move in opposite directions or at different speeds, causing the second sliding members 35 on the two second slide rails 34 to be in different positions. At this time, the adjustment platform 36 will rotate in the horizontal plane, thereby adjusting the angle of the flexible circuit board.

[0026] The third sliding rail 351 and the third sliding block 352 provided on the second sliding member 35 enable the adjustment platform 36 to slide along the X-axis and be rotatably connected to the second sliding member 35. Two sets of second drive components 39 operate independently, driving the adjustment platform 36 to rotate along the horizontal plane, thereby adjusting the angular position of the flexible circuit board and achieving precise positioning with multiple degrees of freedom. This design allows for rotational adjustment of the flexible circuit board, further improving the flexibility and accuracy of positioning and adapting to flexible circuit boards of different shapes and sizes.

[0027] Reference Figure 6 The first drive assembly 38 includes a first mounting bracket 381, a first drive motor 382, ​​a first drive screw 383, a second mounting bracket 384, and a first threaded component 385. The first mounting bracket 381 is mounted on the support frame 33. The first drive motor 382 is connected to the first mounting bracket 381. The output end of the first drive motor 382 is connected to one end of the first drive screw 383. The other end of the first drive screw 383 is screwed into the first threaded component 385. The second mounting bracket 384 is mounted on the frame 10. The first threaded component 385 is connected to the second mounting bracket 384. The first drive motor 382 drives the first drive screw 383 to rotate so that the support frame 33 moves closer to or away from the second mounting bracket 384 along the X-axis direction.

[0028] Understandably, the first drive assembly 38 employs a lead screw drive system, where the first drive motor 382 drives the first drive lead screw 383 to rotate, thereby moving the support frame 33 along the X-axis. The lead screw drive system features high precision, high rigidity, and self-locking characteristics, ensuring the accuracy and stability of the support frame 33's movement. The first mounting bracket 381 and the second mounting bracket 384 respectively fix the first drive motor 382 and the first threaded component 385, providing a reliable support structure. This design makes the movement of the automatic positioning mechanism 30 in the X-axis direction more precise and controllable, thus improving overall positioning accuracy.

[0029] Reference Figure 6 The second drive assembly 39 includes a second drive motor 391 and a second drive screw 392. The second drive motor 391 is mounted on the support frame 33. One end of the second drive screw 392 is connected to the output end of the second drive motor 391, and the other end is screwed onto the second sliding member 35. The second drive motor 391 drives the second drive screw 392 to rotate so that the second sliding member 35 moves closer to or away from the second drive motor 391 along the Y-axis.

[0030] Understandably, the second drive assembly 39 also employs a lead screw drive system. The second drive motor 391 drives the second drive lead screw 392 to rotate, thereby moving the second sliding member 35 along the Y-axis. The lead screw drive provides high-precision linear motion, ensuring the positioning accuracy of the adjustment platform 36 in the Y-axis direction. The second drive motor 391 is mounted on the support frame 33, resulting in a compact structure and reduced space occupation. This design makes the movement of the automatic adjustment mechanism 30 in the Y-axis direction smoother and more accurate, coordinating with the X-axis movement to achieve precise positioning in a two-dimensional plane.

[0031] Reference Figure 4 and Figure 6 The detection component 37 includes an illumination device 361 and a vision inspection device 362. The illumination device 361 is mounted on the frame 10 and located directly below the Z-axis of the positioning platform 36. The vision inspection device 362 is mounted on the frame 10 and located directly above the Z-axis of the positioning platform 36. The positioning platform 36 is made of transparent material. The illumination device 361 is configured to provide a light source for the vision inspection device 362 to capture images. The vision inspection device 362 is configured to detect the deviation between the positioning holes and the set positions on the flexible circuit board.

[0032] Understandably, the detection component 37, through the cooperation of the illumination device 361 and the vision inspection device 362, achieves non-contact detection of the positioning holes on the flexible circuit board. The illumination device 361 provides a light source from below the adjustment platform 36, while the vision inspection device 362 captures images from above. Since the adjustment platform 36 is made of transparent material, light can pass through, ensuring the clarity of the image acquisition. The vision inspection device 362 can detect the deviation between the positioning hole and the set position with high precision, providing accurate feedback signals to the automatic adjustment mechanism 30, thereby achieving rapid and precise positioning adjustment.

[0033] Reference Figure 4 The visual inspection device 362 consists of at least two sets of visual inspection cameras.

[0034] Understandably, setting up at least two sets of vision inspection cameras allows for the simultaneous inspection of multiple positioning holes on a flexible circuit board from different angles or positions, improving inspection efficiency and accuracy. Multiple sets of vision inspection cameras can cover a larger inspection area, reduce blind spots, and ensure that positional deviations of the positioning holes are fully captured. This design is particularly suitable for large or complex-shaped flexible circuit boards, further enhancing the adaptability and reliability of the automatic positioning device.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
