For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0024] In one embodiment of the present application, as shown in Figs. 1-5 A stretching and flattening suction cup mechanism is provided, which comprises a main frame 1 and a suction cup group 2 located at the edge of the main frame 1, the main frame 1 extends in four directions with a sliding seat 3, the sliding seat 3 is provided with a gas cylinder 31 and an adjusting position 32 arranged on the side surface of the gas cylinder 31, the adjusting position 32 movably connects with a movable block 33, the output shaft of the gas cylinder 31 is connected with the movable block 33, the adjusting position 32 comprises a limiting block 321 and a front stop block 322, the limiting block 321 is limitedly matched with one side of the movable block 33, the front stop block 322 is limitedly matched with the other side of the movable block 33, and the bottom of the movable block 33 is connected with the suction cup group 2.

[0025] Further, the front stopper 322 is an L-shaped structure, and a plurality of adjusting holes 323 are arranged on the connection position between the front stopper 322 and the sliding seat 3, which are used to realize the fixed installation of the front stopper 322 and the sliding seat 3. The adjusting holes 323 are arranged towards the suction cup group 2. A plurality of installation holes 34 are arranged on the sliding seat 3 in a transverse direction, and each installation hole 34 corresponds to each adjusting hole 323. Specifically, according to the various indicators of the plate, the space size of the adjusting position 32 can be adjusted by installing different adjusting holes 323 and corresponding installation holes 34, that is, the distance between the front stopper 322 and the side surface of the movable block 33 is adjusted. When adjusting, the adjusting hole 323 on the front stopper 322 is selected to adjust the length of the front stopper 322 extending out of the sliding seat 3, and then the adjusting hole 323 is fixedly installed with the corresponding installation hole 34 through the mounting piece. It is worth noting that the longitudinal distance between two adjacent adjusting holes 323 is 0.9 mm, the number of adjusting holes 323 is at least four, and each adjusting hole 323 is distributed from back to front in a diagonal direction, so that the two adjacent adjusting holes 323 also have a certain transverse distance, avoiding the position conflict between the two adjusting holes 323.

Specifically, the avoidance position 21 is arranged on one of the suction cup groups 2, and when the plate member is gripped, the suction cup group 2 provided with the avoidance position 21 is aligned with the side of the plate member having the two-dimensional code, and the avoidance effect is achieved through the avoidance position 21 corresponding to the position of the two-dimensional code.

[0030] Working principle: when in use, the main frame 1 is driven to the upper side of the plate member by the mechanical arm, and the plate member is gripped by the suction cup group 2, and then the plate member is lifted by the suction cup group 2, after being lifted, the movable block 33 is pushed to move away from the center of the main frame 1 by the cylinders 31 on the main frame 1, so as to stretch and flatten the plate member, when the front side of the movable block 33 abuts against the front baffle, the movement is stopped, so as to avoid tearing the plate member during the stretching process; after the plate member is placed on another carrier by the mechanical arm driving the main frame 1, the suction cup group 2 releases the plate member, and the movable block 33 is pulled back by the cylinders 31, so that the rear side of the movable block 33 abuts against the limiting block 321, so as to ensure that the suction cup group 2 has a moving and stretching space when the next plate member is adsorbed, and the continuity is good.
