[0039] The adjustable spacing of the gripper bars 32 can accommodate PCBs of different sizes, enhancing the versatility of the mechanism. The gear 73 and rack 74 transmission method makes the gripper movement more precise and stable. The camera 8 can monitor the gripping status of the PCB in real time, detect gripping abnormalities in a timely manner, and improve the reliability of the production process. At the same time, the gear 73 and rack 74 can increase the travel of the left gripper 2 and the right gripper 3, expanding the range of PCBs that can be adapted.
[0040] The gripper mounting component includes a mounting plate 61 and a snap-fit block 62. Two sets of mounting plates 61 and snap-fit blocks 62 are provided corresponding to the left slide plate 71 and the right slide plate 72, respectively. The two mounting plates 61 are connected to the side walls of the left slide plate 71 and the right slide plate 72, respectively. The snap-fit block 62 is installed on the side wall of the mounting plate 61. A snap-fit groove 63 is provided between the mounting plate 61 and the snap-fit block 62. The left gripper 2 and the right gripper 3 can be vertically inserted into the snap-fit groove 63. A quick-change head 64 is provided on the mounting plate 61. The quick-change head 64 is used to install the left gripper 2 and the right gripper 3 on the mounting plate 61.

The side of the gripper plate 31 is provided with multiple mounting holes 35, and the gripper rod 32 is mounted on the gripper plate 31 through the mounting holes 35.
[0043] This makes the installation and removal of the gripper bar 32 more convenient and quick, while ensuring the stability and reliability of the gripper bar 32. Furthermore, the installation position of the gripper bar 32 can be adjusted according to the actual size of the PCB board to accommodate the gripping of PCB boards of different sizes.
[0044] The drive assembly 7 also includes a transmission belt 75, a drive pulley 76, a driven pulley 77, and a drive motor 78. The drive pulley 76 and the driven pulley 77 are rotatably connected to the side wall of the top of the mounting body 1. The drive pulley 76 is driven to rotate by the drive motor 78. The transmission belt 75 is sleeved on the circumferential surface of the drive pulley 76 and the driven pulley 77, and the surfaces of the drive pulley 76 and the driven pulley 77 are meshed with the surface teeth of the transmission belt 75. The driven pulley 77 is coaxially arranged with the gear 73, and the output end of the driven pulley 77 passes through the mounting body 1 and is connected to the rotating shaft of the gear 73.
[0045] During the clamping drive process, the drive motor 78 drives the drive wheel 76 to rotate, the drive wheel 76 drives the transmission belt 75 to move, and the transmission belt 75 further drives the driven wheel 77 to rotate, so that the driven wheel 77 drives the transmission gear plate to rotate stably. The structure is simple and efficient, and can stably drive the left slide plate 71 and the right slide plate 72 to move in opposite directions, further increasing the stability of the gripper structure.
[0046] The bottom of the mounting body 1 has two sliding rails 11 corresponding to the left sliding plate 71 and the right sliding plate 72. The sliding rails 11 are parallel to the length direction of the left sliding plate 71. The two sliding rails 11 are respectively set on both sides of the gear 73. The left sliding plate 71 and the right sliding plate 72 are slidably engaged with the sliding rails 11.
[0047] This makes the opposing movement of the left slide plate 71 and the right slide plate 72 more stable, thereby further increasing the stability of the left gripper 2 and the right gripper 3 when gripping the PCB board. At the same time, it makes the structure between the components more compact and increases the overall stability of the structure.
[0048] The gripper bar 32 is inclined toward the gripping direction, and a gripping contact 36 is provided at the end of the gripper bar 32 away from the right slide plate 72.
[0049] The inclined gripper bar 32 and gripping contact 36 design enable the gripper mechanism to better adapt to PCBs of different shapes and sizes, improving gripping flexibility and accuracy.
[0050] The mounting body 1 is also provided with a sensing component 4, which includes a laser emitter 41, a sensing block 42, and a sensing part 43. The laser emitter 41 is mounted on the mounting body 1, the sensing block 42 is mounted on the side of the right sliding plate 72, and the sensing part 43 is mounted on the side of the mounting body 1. The sensing part 43 has a strip-shaped sensing groove 44 corresponding to the sensing block 42. The sensing block 42 moves with the right sliding plate 72 to extend into or out of the sensing groove 44. The corresponding sensing part 43 is placed at the emitting end of the laser emitter 41.
[0051] The sensing block 42 moves with the right-side sliding plate 72, extending into or retracting from the sensing slot 44, thereby achieving position detection and feedback. Simultaneously, a corresponding sensing part 43 is placed on the laser emitter 41 to monitor the status of the sensing part 43 in real time. The design of the sensing assembly 4 enables real-time monitoring of the position status of the right-side sliding plate 72 and the gripper assembly, providing a reliable basis for precise control. Furthermore, the laser emitter 41 further improves the accuracy and reliability of the monitoring.
[0052] The drive end of the drive motor 78 is horizontally mounted on the mounting plate 61, and the mounting position of the drive motor 78 is parallel to the transmission belt 75; a protective cover 5 is provided on the mounting body 1, which covers the drive motor 78.
[0053] This design allows for a more compact structure between the drive assembly 7 and the mounting body 1, reducing wobbling during movement and resulting in more stable clamping of the PCB board. The protective cover 5 enhances the safety and reliability of the drive motor 78, extending its service life. Simultaneously, it maintains the neatness and aesthetics of the entire gripper mechanism.
[0054] The implementation principle of the PCB board cutting machine gripper mechanism in this application embodiment is as follows: Based on the mounting body 1 as the basic frame, the left and right grippers are efficiently interchanged via quick-mount components 6. The spacing between the gripper rods 32 can be flexibly adjusted to adapt to different PCB board specifications. The drive assembly 7 adopts a gear 73 and rack 74 transmission structure, combined with a pulley system to transmit power, achieving synchronous reverse movement of the grippers and ensuring a stable and reliable gripping process. In terms of spatial layout, the drive motor 78 is arranged parallel to the transmission system. The left slide plate 71, right slide plate 72, and gear 73 have a compact positional relationship, ensuring stable transmission and optimizing the overall structure of the mechanism. The detection system integrates a laser emitter 41 and a camera 8 to monitor the gripper position and PCB gripping status in real time. The protection system uses a protective cover 5 to effectively protect the drive assembly 7 from external interference. This solution, through the combination of mechanical structure optimization and intelligent detection technology, achieves rapid gripper replacement, adaptive adjustment, and high-precision positioning, meeting the automated production needs of multi-specification PCB boards.
