[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-5 A novel gripper cylinder mechanical handpiece includes: a connecting plate 1, an air passage plate 11 for supplying air to a suction cup assembly 3, and a mounting plate 12 for mounting the suction cup assembly 3 and a gripping assembly 4; a moving assembly 2, disposed at the lower end of the connecting plate 1, for adjusting the distance between the pair of air passage plates 11; a suction cup assembly 3, disposed on the mounting plate 12, for gripping a circuit board from above; and a gripping assembly 4, disposed on the mounting plate 12, for gripping the circuit board from the side. In this embodiment, the connecting plate 1 is mounted on the robotic arm, thereby facilitating the movement of the control device.

[0026] The working principle of this utility model is as follows: by setting the movable component 2, the suction cup component 3 and the clamping component 4 can be moved easily, so that the clamping components 4 on both sides can cooperate with each other to fix the circuit board from the side. It also realizes the adjustment of the position of the suction cup component 3, which is convenient for fixing circuit boards of different sizes. By setting the suction cup component 3, the circuit board can be easily sucked from the top, thereby completing the fixing of the circuit board from the top. It is convenient for fixing different circuit boards and can expand the application range of the device.

[0027] As a further embodiment, the movable component 2 includes a movable bracket 21 mounted on the lower end of the connecting plate 1. A first fixed base plate 22 and a second fixed base plate 25 are also mounted on both sides of the lower end of the movable bracket 21. A movable lead screw 24 is rotatably mounted between the first fixed base plate 22 and the second fixed base plate 25. A movable motor 23 for driving the movable lead screw 24 is also mounted at the end of the first fixed base plate 22. A movable slide block 26 is slidably mounted inside the movable bracket 21. The movable slide block 26 is threaded onto the movable lead screw 24. A connecting seat 27 for fixing the air passage plate 11 is also mounted on the lower end of the movable slide block 26. The movable slide block 26 is slidably mounted inside the movable bracket 21 via a movable slide rail 29. A baffle 28 is also installed between the first fixed base plate 22 and the second fixed base plate 25. The movable slide block 26 and the connecting seat 27 have openings 281 corresponding to the positions of the baffle 28. By setting the baffle 28, impurities inside the movable bracket 21 can be effectively prevented from falling onto the circuit board. By setting the movable component 2, the positions of the suction cup component 3 and the clamping component 4 can be easily adjusted, making it convenient to fix circuit boards of different sizes.

[0028] The working principle of the moving component 2 is as follows: the moving motor 23 is started, and the moving screw 24 is rotated by the moving motor 23, which causes the moving slide 26 threaded on the moving screw 24 to move the corresponding air circuit board 11, so that the clamping component 4 on this side is close to the clamping component 4 on the other side, so that the circuit board can be fixed by the clamping component 4.

[0029] As a further embodiment, the suction cup assembly 3 includes a hollow suction cup connecting rod 31 slidably inserted into the mounting plate 12. A suction cup 33 is fixed to the lower end of the suction cup connecting rod 31, and a vent pipe 34 is installed at the upper end of the suction cup connecting rod 31. The vent pipe 34 communicates with the air passage plate 11. A compression spring 32 is also fitted onto the suction cup connecting rod 31, with its two ends respectively contacting the suction cup 33 and the corresponding side of the mounting plate 12. In this embodiment, an air pump is installed on the air passage plate 11. By pumping air, the suction cup 33 can be used to hold the circuit board. The compression spring 32 facilitates the repositioning of the suction cup 33.

[0030] The working principle of the suction cup assembly 3 is as follows: When in use, the device moves down to bring the suction cup 33 close to the upper end of the circuit board. At this time, the suction cup connecting rod 31 moves upward, the compression spring 32 is compressed, and then the air pump draws air, so that the suction cup sucks out the circuit board, thus completing the gripping work.

[0031] As a further embodiment, the clamping assembly 4 includes a clamping cylinder 41 mounted on the mounting plate 12. The telescopic end of the clamping cylinder 41 passes through the mounting plate 12 and is mounted on a fixed seat 42. A clamping rod 43 is mounted on the fixed seat 42. A horizontally arranged clamping pressure plate 44 is mounted on the lower half of the clamping rod 43. A clamping side plate 45 is also mounted on the end of the clamping rod 43. Rubber pads are provided on the side of the clamping pressure plate 44 and the clamping side plate 45 near the circuit board. In this embodiment, multiple air supply seats 13 are also mounted on the air circuit plate 11. Adjacent air supply seats 13 are connected by air supply pipes 14. Each air supply seat 13 is also equipped with an air supply pipe for supplying air to the clamping cylinder 41. Obviously, an air pump is provided on the air supply seat 13 to facilitate the supply of air to the clamping cylinder 41. By setting up the clamping assembly 4, a stable clamping force is provided to prevent the circuit board from shaking or falling during transportation.

[0032] The working principle of the clamping component 4 is as follows: During clamping, the clamping cylinder 41 pushes the fixed seat 42 down, thereby causing the clamping pressure plate 44 on the clamping rod 43 to move down and adjust the height of the clamping pressure plate 44. Then, the moving component drives the air circuit plate 11 to move, thereby realizing the movement of the mounting plate 12, and thus bringing the clamping side plates 45 on both sides closer to each other, so that the circuit board can be clamped from the side. By setting rubber pads, the possibility of damage to the circuit board can be effectively reduced.

[0033] As a further solution, an ultrasonic detector 5 is also installed on the air circuit board 11. By setting the ultrasonic detector 5, it is convenient to measure the distance between the device and the circuit board, thereby facilitating the control of the clamping component 4 and effectively reducing the possibility of damaging the circuit board due to excessive clamping force when the clamping component 4 is used.

[0034] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model.
