Description

Technical Field

[0001] This utility model relates to the technical field of hardware processing fixtures, specifically to a suction cup fixture with protective function. Background Technology

[0002] Suction cup clamps are widely used in automated production lines, especially for clamping and transferring thin sheet metal parts. In some production processes, it is necessary to alternately feed sheets of different sizes. Current technology uses robots to alternately control two types of clamps for feeding, which results in poor clamp versatility, occupies more production space, and leads to complex production processes and higher production costs.

[0003] To address the aforementioned issues, patent number 201821209786.8 discloses a suction cup clamp, comprising a long, narrow clamp body. Several negative pressure suction cups arranged along the clamp body's extension direction are fixedly mounted below the clamp body. Several short rods are also spaced apart on the clamp body, extending perpendicularly to the clamp body's extension direction. A negative pressure suction cup is fixedly mounted below each of the two ends of each short rod. All the negative pressure suction cups fixed to the clamp body have interconnected air passages, forming a first suction cup group. All the negative pressure suction cups fixed to the short rods have interconnected air passages, forming a second suction cup group. An adapter block for connection to a robot is fixedly mounted above the clamp body. This suction cup clamp, with two independently controlled first and second suction cup groups, can alternately clamp sheet metal parts of different sizes, saving production space, simplifying the process, improving production efficiency, and reducing production costs. However, the existing suction cup clamp still has the following problems: 1. The existing suction cup clamp has no limit protection function. When the suction cup collides with the workpiece due to improper operation, the suction cup clamp cannot retract to protect itself, which will lead to damage to the suction cup, shorten its service life, and may also damage the workpiece, resulting in increased production costs; 2. The existing suction cup clamps mostly use a single suction nozzle to adsorb and hold the workpiece. The suction force is poor, and the single suction nozzle will age after long-term use, resulting in a decrease in suction force, affecting the clamping stability, and causing the clamped workpiece to fall off, which cannot meet the usage requirements of the existing suction cup clamp.
