Description

Automatic sand changing table

Technical Field

The invention relates to the field of sand changing tables, in particular to an automatic sand changing table.

Background

The automatic sand changing table is used for matching and a robot to complete the work of changing the sand paper, and achieves the functions of tearing off the old sand paper and pasting the sand paper with required specifications.

The automatic sand changing table disclosed by the application publication number CN109822436A comprises a base, a box body, a dustproof cover, a sand paper sticking mechanism, a sand paper detection device, a sand paper tearing mechanism and a sand receiving box, wherein the box body is arranged on the base; the dustproof cover is connected to the top end of the box body in an openable and closable manner; the sand paper detection device and the sand paper sticking mechanism are respectively arranged on the sand sticking mounting seat; the top end of the front side plate of the box body is provided with a sand pulling mounting seat, and the sand pulling mounting seat is positioned right in front of the sand sticking mounting seat; the sand tearing mechanism is arranged on the sand tearing mounting seat; the sand receiving box is detachably arranged on the front side of the sand pulling mounting seat. There are several technical drawbacks: 1. the automatic sand changing table effectively solves the problem of sand paper changing; but the structure is designed more complex. 2. This automatic trade sand table abrasive paper and place subassembly has a gag lever post all around, can prevent that abrasive paper adhesion from dropping when falling back, nevertheless falls back abrasive paper and may be crooked, and abrasive paper pastes the position just when leading to changing abrasive paper next time. 3. After the sand paper is replaced by the robot, the sand paper can be not firmly adhered and is easy to fall off in the moving process.

An automatic sand-changing device, as disclosed in application publication No. CN111037460A, comprises a manipulator for fixing an adhesive member for adhering sandpaper, the sandpaper being formed with through holes, and a control device for controlling the manipulator to move the adhesive member. The automatic sand changing device further comprises a sand tearing piece with a hook part, the adhesive piece has elasticity, the control device controls the manipulator to move the adhesive piece to a sand taking position where sand paper is placed to adhere the sand paper, the control device also controls the manipulator to move the adhesive piece to the position above the sand tearing piece after the sand paper on the adhesive piece polishes the workpiece according to a preset rule, the manipulator is controlled to move the sand paper in a first direction close to the hook part to enable the hook part to penetrate through the through hole and abut against the adhesive piece to place the hook part on one side of the adhesive piece close to the adhesive piece, and the manipulator is controlled to move the sand paper in a second direction perpendicular to the first direction to enable the hook part to hook the sand paper and tear the sand paper when the adhesive piece is moved away from the hook part in the first direction, so that the following defects of the sand paper exist, and the problem of sand paper changing is effectively solved, 1; but requires the use of a sander having a central hole. 2. The automatic sand changing device is too simple, and easily causes collision and abrasive paper tearing failure. 3. The automatic sand changing device has less sand paper storage and needs frequent feeding. Further provides an automatic sand changing table.
