Description

Technical Field

[0001] The utility model relates to the field of flexible suction cups for mechanical arms, and more specifically, to a flexible suction cup for mechanical arms of an industrial defect detection training platform. Background Art

[0002] The industrial defect detection training platform is a device used to detect the degree of defects in workpieces. Generally, the workpiece is placed on a belt conveyor first, and then transported to the bottom of the detection camera bracket. It is illuminated by the illumination lamp installed on the detection camera bracket and then photographed by the detection camera. The photographed image is then transmitted back to the detection control module for internal calculation and recognition. At the same time, the belt conveyor drives the workpiece forward to the robotic arm, which automatically clamps the workpiece and places it in the good product area or the defective product area through several flexible suction cup bodies to complete the rapid detection of the workpiece.

[0003] Based on the above, the inventors found in actual use that most of the silicone suction cups on the robotic arms of existing industrial defect detection training platforms only have one and a small number, which easily affects the stability of clamping, and the bottom edge shape of the silicone suction cup is relatively regular, which is not conducive to clamping workpieces with complex surface structures, and the bottom edge is prone to air leakage and loose clamping. Therefore, we proposed a flexible suction cup for the robotic arm of an industrial defect detection training platform to solve the above-mentioned problems. Utility Model Content

[0028] The adsorption and clamping principle of this kind of flexible suction cup body is:

[0029] When the workpiece moves to one side of the robot arm 4, the robot arm 4 drives the vacuum box body 1 to move to the top of the workpiece and presses down on the top of the workpiece. At this time, the several flexible suction cup bodies 2 at the bottom of the vacuum box body 1 automatically expand and contract at the bottom of the vacuum box body 1 according to the structural form of the top of the workpiece to adapt to the structural form of the top of the workpiece.
