Abstract
Description
Technical Field
[0001] This utility model relates to the field of gripping and transfer technology, specifically a highly stable gripping and transfer mechanism. Background Technology
[0002] The adsorption transplanter is an automated device that uses vacuum adsorption technology to grasp and precisely transplant materials. Its core design combines mechanical transmission, control system and adsorption components.
[0003] For example, a small material adsorption and transfer platform with application number CN221643981U has a transmission mechanism that moves the adsorption mechanism along the base to one side of the small material pile. At this time, the adsorption plate is located directly above the small material. The hydraulic telescopic rod is activated to extend and push the adsorption plate downward, pushing the suction plate to a position close to the upper surface of the small material. The vacuum pump located at the bottom of the vertical groove is activated. The vacuum pump extracts the air inside the cavity through the first hose, the second hose and the third hose. As the air inside the cavity gradually decreases, the suction plate will be recessed into the cavity, thereby forming a vacuum state between the suction plate and the small material. Small pieces of material can then be adsorbed onto the bottom of the adsorption plate. A hydraulic telescopic rod moves the material to the bottom of the support arm. A transmission mechanism moves the adsorption mechanism, holding the material, along the base to a designated position. A vacuum pump then blows air into the cavity, causing the material to detach from the bottom of the suction cup, completing the adsorption and transfer of the small pieces. This vacuum adsorption method makes loading and unloading small pieces of material relatively convenient. However, the suction cup is of a fixed size, limiting its ability to adsorb materials of only one size and failing to meet the needs of adsorbing, grasping, and transferring materials of various sizes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1
[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a highly stable gripping and transferring mechanism, including a guide rail 1, a fixed frame 5 slidably connected to the top of the guide rail 1, two electric telescopic rods 6 fixedly connected to the top of the fixed frame 5, the telescopic ends of the electric telescopic rods 6 extending to the bottom of the fixed frame 5 and fixedly connected to connecting blocks 7, a guide frame 8 fixedly connected to the bottom of the two connecting blocks 7, four guide grooves 9 opened at the bottom of the guide frame 8, a second self-locking motor 10 fixedly connected to one side of the inner cavity of the guide groove 9, a second sliding screw 14 rotatably connected to the other side of the inner cavity of the guide groove 9 through bearings, the output end of the second self-locking motor 10 fixedly connected to one end of the second sliding screw 14, a drive block 11 threadedly connected to the outer side of the second sliding screw 14, a mounting box 12 fixedly connected to the bottom of the drive block 11, and a vacuum suction cup 13 fixedly connected to the bottom of the mounting box 12.
[0021] An air pipe 18 is fixedly connected to the top of the guide frame 8. Several solenoid valves 16 are fixedly connected to the outside of the air pipe 18. A hose 15 is fixedly connected to one end of each solenoid valve 16. One end of each hose 15 extends into the vacuum suction cup 13. The air pipe 18 and the vacuum suction cup 13 are connected through the hose 15 and the solenoid valves 16.
[0022] Several guide blocks 17 are fixedly connected to the top of the guide frame 8. One end of each hose 15 passes through the inside of the guide block 17 and is slidably connected to the inside of the guide block 17, so that the hose 15 is supported by the guide block 17.
[0023] A pump 19 is fixedly connected to one side of the trachea 18, and one end of the pump 19 extends into the trachea 18. A switch valve 20 is fixedly connected to the top of the trachea 18, and the trachea 18 is opened or closed by the switch valve 20.
[0024] Inside the guide rail 1, a first sliding screw 3 is rotatably connected via a bearing. A moving block 4 is threadedly connected to the outer side of the first sliding screw 3. The top of the moving block 4 extends above the guide rail 1 and is fixedly connected to the bottom of the fixed frame 5. The moving block 4 and the fixed frame 5 are moved by the first sliding screw 3.
[0025] Example 2
[0026] Please see Figure 1 The present invention provides a technical solution: a first self-locking motor 2 is fixedly connected to one side of the guide rail 1, the output end of the first self-locking motor 2 is fixedly connected to one end of the first sliding screw 3, and a controller 21 is fixedly connected to one side of the guide rail 1, and the mechanism is controlled by the controller 21.
[0027] In summary, this highly stable gripping and transfer mechanism operates by controlling the first self-locking motor 2 via controller 21. The output of the first self-locking motor 2 drives the first sliding screw 3 to rotate, which in turn drives the moving block 4 and the fixed frame 5 to move. The extension end of the electric telescopic rod 6 then drives the connecting block 7, the guide frame 8, the mounting box 12, and the vacuum suction cup 13 to move. The extension end of the electric telescopic rod 6 then pushes the connecting block 7, the guide frame 8, the mounting box 12, and the vacuum suction cup 13 downwards. The output of the second self-locking motor 10 drives the second sliding screw 14 to rotate, which in turn drives the driving block 11, the mounting box 12, and the vacuum suction cup 13 to move, adjusting the positions of the four vacuum suction cups 13 so that they contact the workpiece surface. Then, the pump 19 starts, extracting gas from the air pipe 18, the solenoid valve 16, the hose 15, and the vacuum suction cup 13, causing the vacuum suction cup 13 to hold the workpiece. Finally, the extension end of the electric telescopic rod 6 drives... The connecting block 7, guide frame 8, and vacuum suction cup 13 move upward, causing the vacuum suction cup 13 to move the workpiece upward. Then, the output end of the first self-locking motor 2 drives the first sliding screw 3 to reset and rotate, causing the first sliding screw 3 to drive the moving block 4, fixed frame 5, electric telescopic rod 6, guide frame 8, and vacuum suction cup 13 to move to the unloading position. Then, the telescopic end of the electric telescopic rod 6 pushes the connecting block 7, guide frame 8, and vacuum suction cup 13 downward. Then, the switch valve 20 opens, causing the air pipe 18, hose 15, and vacuum suction cup to move downward. The vacuum suction cup 13 is connected to the outside world, causing the suction force inside the vacuum suction cup 13 to disappear, allowing the workpiece to fall to the unloading station. By opening the solenoid valve 16, the vacuum suction cup 13 is connected to the solenoid valve 16 and the air pipe 18 through the hose 15. By closing the solenoid valve 16, the vacuum suction cup 13 is disconnected from the air pipe 18. The number of vacuum suction cups 13 that are opened can be adjusted to grip and transfer workpieces of different models. Using multiple vacuum suction cups 13 improves the high stability of gripping and transferring workpieces.
