[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A material-grabbing and adsorption mechanism includes a support, a power mechanism, a linkage mechanism, a connecting frame, and a material-grabbing mechanism. The support is provided with a fixed plate, and the power mechanism is mounted on the fixed plate. The power mechanism includes a driving wheel and a driven wheel. One end of the linkage mechanism is connected to the driving wheel, and the other end is connected to the driven wheel. The driving wheel and the driven wheel are used to drive the linkage mechanism to swing. The connecting frame is mounted on the linkage mechanism, and the connecting frame is provided with multiple material-grabbing mechanisms. Each material-grabbing mechanism includes a suction cup for picking up materials.
[0005] Furthermore, the power mechanism also includes a motor and a gear belt, with the motor output end connected to the drive wheel, and the drive wheel and the driven wheel connected by a gear belt.
[0006] Furthermore, the power mechanism also includes a pressure wheel, which is mounted on a fixed plate and located on one or both sides of the gear belt for tightening the gear belt.
[0007] Furthermore, the linkage mechanism includes a first connecting rod and a second connecting rod, with the driving wheel and the driven wheel each connected to a first connecting rod, and the two ends of the second connecting rod respectively connected to the free ends of the two first connecting rods.
[0008] Furthermore, the linkage mechanism also includes two limiting posts, which are installed on both sides of the support 1 to limit the rotation range of the first connecting rod.
[0009] Furthermore, the connecting frame includes a first connecting frame, a second connecting frame, and a support frame. One end of the first connecting frame is mounted on the second connecting rod, and the other end is perpendicularly connected to the second connecting frame.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] like Figure 1-5 As shown, a material-collecting and adsorption mechanism includes a support 1, a power mechanism 2, a linkage mechanism 3, a connecting frame 4, and a material-collecting mechanism 5. A fixed plate is provided on one side of the support 1, and the power mechanism 2 is mounted on the fixed plate. The power mechanism 2 includes a driving wheel 21 and a driven wheel 22. One end of the linkage mechanism 3 is connected to the driving wheel 21, and the other end is connected to the driven wheel 22. The driving wheel 21 and the driven wheel 22 cooperate to drive the linkage mechanism 3 to swing. The connecting frame 4 is mounted on the linkage mechanism 3 and has multiple material-collecting mechanisms 5. Each material-collecting mechanism 5 includes a suction cup 51 for collecting materials. The power mechanism 2 drives the linkage mechanism 3 to swing left and right. The power mechanism 2 also includes a motor 23 and a gear belt 24. The output end of the motor 23 is connected to the drive wheel 21, and the drive wheel 21 is connected to the driven wheel 22 through the gear belt 24. That is, when the motor 23 is powered on, it drives the drive wheel 21 to rotate, and the drive wheel 21 drives the driven wheel 22 to rotate synchronously through the gear belt 24. The power mechanism 2 also includes a pressure wheel 25, which is mounted on a fixed plate and set on one or both sides of the gear belt 24. By adjusting the installation position of the pressure wheel 25, the gear belt 24 is tightened to prevent the gear belt 24 from slipping, thus ensuring the reliability, efficiency and lifespan of the belt drive.
[0024] like Figure 3 As shown, the linkage mechanism 3 includes a first connecting rod 31 and a second connecting rod 32. The driving wheel 21 and the driven wheel 22 are each connected to one of the first connecting rods 31. The two ends of the second connecting rod 32 are rotatably connected to the free ends of the two first connecting rods 31. The linkage mechanism 3 also includes two limiting posts 33, which are installed on both sides of the support 1 to limit the rotation angle of the first connecting rods 31. Figure 4 As shown, the connecting frame 4 includes a first connecting frame 41, a second connecting frame 42, and a support frame 43. One end of the first connecting frame 41 is mounted on the second connecting rod 32, and the other end is perpendicularly connected to the second connecting frame 42. Multiple Z-shaped support frames 43 are detachably connected to the lower end of the second connecting frame 42 along its length. Each support frame 43 has two connection holes for installing the material picking mechanism 5. The position and number of the material picking mechanism 5 on the connection holes can be adjusted according to product needs to ensure that the position of the suction cup 51 of the material to be adsorbed matches the size of the material to be adsorbed. The support frame 43 is arranged in a Z-shape, which can make the mechanism more stable. Reinforcing ribs are provided at the connection between the first connecting frame 41 and the second connecting frame 42 to make the connection more stable.
[0025] In implementation, the motor 23 is mounted on the fixed plate of the support 1 in a front-to-back direction. Taking the motor 23 as the rear as an example, one end of the driving wheel 21 and the driven wheel 22 are respectively inserted through the front end onto the fixed plate. The rear end of the driving wheel 21 is connected to the output end of the motor 23. After the motor 23 is powered on, it drives the driving wheel 21 to rotate. The driving wheel 21 drives the driven wheel 22 to rotate synchronously through the gear belt 24, thereby driving the first connecting rod 31 to rotate left and right, and then driving the second connecting rod 32 to move up and down. Through the cooperation of the first connecting rod 31 and the second connecting rod 32, the connecting frame 4 moves left and right and up and down. When the first connecting rod 31 rotates to the left or right to the horizontal position, it abuts against the limiting post 33, that is, the limiting post 33 limits the first connecting rod 31 to rotate between 0° and 180°. When picking up materials, the first connecting rod 31 first rotates to the left to the horizontal position, causing the second connecting rod 32 to descend. The material is lowered to its lowest position, causing the connecting frame 4 to descend to its lowest position. At this time, the material-picking mechanism 5 reaches the surface of the material to be adsorbed and picks up the material through the suction cup 51. After the material is adsorbed, the motor 23 reverses, causing the first connecting rod 31 to rotate to the right to a horizontal position. This drives the second connecting rod 32 to move upward to the highest point and then downward to the lowest point. At this time, the material-picking mechanism 5 reaches the material-discharging area and releases the material through the suction cup 51. Then, the first connecting rod 31 is rotated to a vertical position, causing the second connecting rod 32 to rise to the highest position, completing one motion cycle. Repeating this cycle can realize the cyclic picking and discharging of materials. By setting the length of the first connecting rod 31 and the second connecting rod 32, the stroke of the material-picking mechanism 5 can be set. The picking and discharging process can be completed by a single power mechanism 2, which can complete the picking and discharging of materials in the vertical direction and the translation of materials in the horizontal direction. The control process is simple, the movement speed is fast, and the efficiency is high.
[0026] like Figure 4 As shown, the material handling mechanism 5 also includes a suction rod 52, a threaded sleeve 53, and a floating spring 54. The bottom end of the suction rod 52 is connected to the suction cup 51, and the top end is connected to the vacuum generator through a conduit. The threaded sleeve 53 is slidably inserted around the suction rod 52. The floating spring 54 is sleeved around the suction rod 52, with one end connected to the lower end of the suction rod 52 and the other end connected to the lower end of the threaded sleeve 53. Two nuts are provided around the threaded sleeve 53 to fix the position of the threaded sleeve 53 relative to the support frame 43. The outer contour of the suction rod 52 is a polygonal structure, and the inner ring of the threaded sleeve 53 is adapted to the outer contour of the suction rod 52. The polygonal structure of the outer contour of the suction rod 52 is used to prevent the suction rod 52 from rotating during the material handling process, ensuring the stability of material handling and transportation.
[0027] During implementation, when the connecting frame 4 reaches its lowest position during the material handling process, the connecting frame 4 pushes the material handling mechanism 5 downward, that is, pushes the threaded sleeve 53 to move downward along the suction rod 52 to compress the floating spring 54, so that the suction cup 51 adheres to the material. By setting a vacuum generator to evacuate the suction cup 51, the material is adsorbed. After the material is adsorbed, the suction cup 51 moves to the discharge area to release the material.
[0028] The working principle of a material-picking and adsorption mechanism is as follows: During material picking, the motor 23 rotates the first connecting rod 31 to the left to a horizontal position, causing the second connecting rod 32 to descend to its lowest position, which in turn causes the connecting frame 4 to descend to its lowest position. The connecting frame 4 pushes the material-picking mechanism 5 downward, that is, it pushes the threaded sleeve 53 downward to compress the floating spring 54, causing the suction cup 51 to adhere to the material. A vacuum generator is used to evacuate the suction cup 51 to achieve material adsorption. After the material is adsorbed, the motor 23 reverses, causing the first connecting rod 31 to rotate to the right to a horizontal position, which drives the second connecting rod 32 to move upward to the highest point and then downward to the lowest point. At this time, the material-picking mechanism 5 reaches the discharge area. The vacuum generator causes the suction cup 51 to release the material. Then, the motor 23 rotates the first connecting rod 31 to a vertical position, causing the second connecting rod 32 to rise to its highest position, that is, the material-picking mechanism 5 reaches its highest position, completing one motion cycle. Repeating this cycle can achieve cyclic material picking and discharging.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
