Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-3, a suction cup gripping mechanism comprises a mounting frame 1, wherein the mounting frame 1 can be mounted on a gripping device. The mounting rack 1 is provided with a small gear 31 driven by the gear motor 2 and a big gear 32 engaged with the small gear 31, and the big gear 32 is fixedly provided with a swing arm support 4. The swing arm support 4 is provided with a swing shaft 5, the swing shaft 5 is sleeved with a swing frame 6, the swing frame 6 is connected with the swing shaft 5 through four reset springs 7, and four swing arms 8 are fixedly connected at the same time. The small gear 31 drives the big gear 32 to rotate through the motor 2, the big gear 32 drives the swing arm support 4 to rotate together, and the swing arm 8 also rotates together with the support 4. The swing arm 8 can swing at plus and minus 4 degrees around the swing shaft 5 while rotating, and can return to the positive under the action of the return spring 7.

The four swing arms 8 comprise two long swing arms and two short swing arms, and can avoid a door leaf lock hole when in use, the tail ends of the swing arms are fixedly connected with a universal sucker structure 9, in the universal sucker structure 9, a sucker 91 is fixedly connected with a sucker support seat 92 through a screw, a joint ball hinge 95 is arranged at the tail end of a sucker shaft 93, the sucker support seat 92 is tightly matched with the outer ring of the joint ball hinge 95, the inner ring of the joint ball hinge 95 is tightly matched with the sucker shaft 93, and the sucker shaft 93 and the sucker 91 can swing in any direction of plus or minus 7 degrees; a linear bearing 96 and a compression spring 94 are sleeved outside the sucker shaft 93, the linear bearing 96 is fixed in a through hole at the tail end of the swing arm 8, and the compression spring 94 is abutted between the sucker support seat 92 and the swing arm 8 to provide a certain pressing force for the sucker 91; the suction cup 91 is provided with a pipe joint and an air pipe which are directly communicated with the air storage tank and the vacuum generator. In the universal sucking disc structure 9 that long swing arm connected, the sucking disc axle 93 end is equipped with one and stretches out length adjusting sleeve 97, can adjust the length that sucking disc axle 93 stretches out swing arm 8 through taut sucking disc axle screw 98, and then guarantees that sucking disc 91 in the long swing arm also can realize fine contact with the door leaf. For example, when the door leaf is a bent door, the bending angle of the bent door is 10 degrees, the single side is 5 degrees, the vertical distance difference exists between the long swing arm and the short swing arm and the door leaf, the long swing arm is 120mm longer than the short swing arm, according to calculation, the distance difference is 120tan5 degrees and is not less than 10.5mm, and at the moment, the sucker shaft 93 is adjusted, so that theoretically, four suckers 91 can be in good contact with the door leaf; when the door leaf is a flat door, the sucker extension length adjusting sleeve 97 can be detached.
