Technical Field

The invention is mainly applied to buffer material receiving in the feeding process of the manipulator.

Background

Workpieces are fed and discharged by a mechanical arm in the batch processing production process, and the actions of grabbing and placing the workpieces are indispensable. After finish machining or workpieces with fragile materials, the most basic requirement is to lightly hold and slowly release the workpieces to prevent gouges. However, when the manipulator places the workpiece, the clamping jaw cannot be loosened after the workpiece is in zero-distance contact with the placing platform, a certain distance is always kept, the clamping jaw is loosened, and the workpiece has a short-distance free falling process. May result in the risk of gouging or damaging portions of the finished part.

The current conventional damping and buffering method is to use damping materials. But adopt the shock-absorbing material that the shrinkage is big, the problem that exists is that the work piece of different weight can lead to shock-absorbing material compression distance different, and the distance that every kind of work piece descends is different promptly, and the manipulator snatchs once more and can not pinpoint, and uses the shock-absorbing material that the shrinkage is little, can not avoid again completely to knock over or damage.

Preferably, the buffer comprises a damping buffer and a hydraulic buffer; at least two damping buffers are arranged.

By arranging a plurality of damping buffers, the compression amount can be dispersed under the condition that the weight of a workpiece is heavy or large, and the service life of the buffers is prolonged.

Preferably, the damper further comprises a damper mechanism, and the damper mechanism is mounted on a surface of the floating plate away from the damper.

Through set up damper on floating plate, the damage hidden danger of colliding with that the reduction work piece that can furthest appears when placing.

Preferably, the automatic jacking adjusting buffer device further comprises a detection switch, and the detection switch is matched with the output end of the driving piece and is movably arranged on the frame.

The detection switch can send an instruction to the driving piece through detecting the position of the output end of the driving piece according to the requirement of the jacking height, and the in-place automatic start and stop of the driving piece are realized.

Preferably, the jacking transfer machine further comprises a limiting block, wherein the limiting block is located between the jacking plate and the floating plate and fixed on the jacking plate.

The setting of stopper can absorb and offset when the buffer breaks down and loses efficacy, and the work piece is placed at the instantaneous impact force of floating plate, reduces the work piece and kowtow hidden danger. Preferably, the height of the limiting block is smaller than the height of the compressed damping buffer.

According to the technical scheme, the damping buffer has the beneficial effects that the damping buffer can automatically adjust the damping coefficient according to the weight of the workpiece through the weight information of the workpiece fed back by the control assembly, so that the grabbing height can be kept consistent when the grabbing hand grabs the workpiece with the same weight every time, the moving path of the grabbing hand is reduced, the positioning precision is improved, the distance between the workpiece and the placing position of the workpiece can be reduced to the maximum extent, and the collision hidden danger is reduced; and secondly, the buffering function of the buffer and the arrangement of the damping mechanism can avoid the gouging damage of the workpiece to the maximum extent.
