AI Technical Summary
The existing Z-axis module and clamping structure use a lot of actuators to connect them, which makes the structure complex and the lifting stability poor.
By directly connecting the gripping mechanism to the lead screw in the Z-axis module, the triangular transition plate and floating joint in traditional robotic arms are omitted. The axial movement of the lead screw is directly converted into the Z-axis displacement of the gripping mechanism through the cooperation of the lead screw and the transmission mechanism, reducing transmission components and improving space utilization and stability.
The structure of the clamping device has been simplified, the number of parts has been reduced, manufacturing and maintenance costs have been lowered, and lifting stability in the Z-axis direction has been improved.

Abstract
Claims
1. A gripping device, characterized in that The clamping device includes: Z-axis module includes a fixed base, a lead screw movably passing through the fixed base, and a rotating nut sleeved on the outer periphery of the lead screw and threadedly connected to the lead screw, wherein the rotating nut is rotatably disposed on the fixed base; The first drive mechanism is connected to the fixed base; A transmission mechanism, disposed on the fixed base, is tractively connected to the first drive mechanism and the rotating nut. The first drive mechanism drives the rotating nut to rotate via the transmission mechanism, thereby causing the lead screw to move axially along the fixed base; and A clamping mechanism is connected to the lead screw and can move synchronously with the lead screw along the axial direction of the fixed base. The clamping mechanism and the rotating nut are located on opposite sides of the fixed base.
2. Gripping device according to claim 1, characterized in that The clamping device further includes a connecting plate located on the side of the fixed base facing the clamping mechanism, and the connecting plate connects the lead screw and the clamping mechanism.
3. The gripping device of claim 1, wherein The transmission mechanism includes a driving wheel, a timing belt, and a driven wheel. The driving wheel is coaxially and fixedly connected to the output shaft of the first drive mechanism, and the driven wheel is coaxially and fixedly connected to the rotating nut. The driving wheel and the driven wheel are connected by the timing belt.
4. The gripping device of claim 1, wherein The Z-axis module also includes a limiting member, which is disposed in the fixed base and connected to the end of the lead screw near the clamping mechanism to prevent the lead screw from rotating.
5. Gripping apparatus according to claim 4, wherein The limiting component is an anti-rotation nut. One of the anti-rotation nut and the lead screw is provided with a limiting groove, and the other of the anti-rotation nut and the lead screw is provided with a limiting protrusion, and the limiting protrusion is embedded in the limiting groove.
6. Gripping apparatus according to claim 5, wherein The limiting groove is a straight groove, which is located at one end of the lead screw near the clamping mechanism. The limiting protrusion is provided inside the anti-rotation nut, and the straight groove extends axially on the lead screw so that the lead screw can move along its own axial direction.
7. The gripping device of claim 1, wherein The first driving mechanism is a servo motor or a stepper motor, and an encoder is provided on the motor output shaft of the servo motor or the stepper motor.
8. Gripping apparatus according to claim 7, wherein The clamping device further includes a mounting base, which is disposed outside the Z-axis module, and the first drive mechanism is mounted on the mounting base.
9. Gripping device according to any one of claims 1 to 8, characterized in that The clamping mechanism includes: The base is fixedly connected to the end of the lead screw; At least two grippers are symmetrically spaced on the side of the base away from the Z-axis module and are slidably connected to the base; and The second drive mechanism is located on the base and is driven to drive the two grippers to move closer to or further away from each other.
10. Gripping apparatus according to claim 9, wherein The working surface of the gripper is provided with anti-slip texture or flexible pad.
