Technical Field

[0001] This utility model relates to the field of gripping device technology, specifically a pneumatic material gripping device. Background Technology

[0002] In modern manufacturing industries such as automobiles, electronics, food, pharmaceuticals, and logistics, automated production lines have become a core means to improve production efficiency, ensure product quality, and reduce labor costs. As the "hand" of the automation system, the performance of the end effector—that is, the gripper—directly determines the reliability and flexibility of the entire automation unit.

[0003] Among the various types of gripping devices with different drive mechanisms, pneumatic gripping devices occupy a large market share due to their simple structure and cost advantages. Therefore, many large and simple material handling systems also utilize pneumatic clamping. However, the mounting brackets for these grippers often result in bulky structures, increased weight, and decreased dynamic performance. Therefore, we propose a pneumatic material handling gripping device to address these issues. Utility Model Content

[0021] Working Principle: This invention utilizes different clamping materials. The external connector 82 is inserted into the side mounting grooves 84 inside the two sets of fixed seats 83. Then, the locking screw 85 is inserted into the side mounting grooves 84 and the fixed seats 83 to fix the external connector 82 inside the side mounting grooves 84. Afterwards, the control seat 3 is activated by the start switch 5, allowing gas to be delivered through the conveying pipe 9 on the left side of the control seat 3 to the telescopic cylinder 1 at the top of the upper clamping seat 6. The telescopic cylinder 1 drives the connecting block 73 inside the upper clamping seat 6 to extend and retract, causing the connecting block 73 to link with the clamping arm 71 via the linkage rod 74, thus clamping... Arm 71 drives connecting shaft 72 to rotate inside upper clamping seat 6, causing two sets of clamping arms 71 to open and close below upper clamping seat 6. This allows the clamping arms 71 to drive the outer seat 82 and rubber pad 81 to contact and clamp the material. Finally, the outer mounting seat 23 at the top of mounting bracket 21 is connected to the mounting assembly. The clamping arms 71 clamp the item below upper clamping seat 6.
