It is understood that in other embodiments, the automatic abrasive cleaning device may not be provided with the connecting assembly 200, the shaped abrasive tip 300 may be directly connected to the output shaft of the driving member 100, and the driving member 100 can directly drive the shaped abrasive tip 300 to perform the lifting and rotating motion.

In one embodiment, the driving member 100 is a servo motor, the servo motor drives the connecting assembly 200 and the special-shaped grinding head 300 to rotate, so as to perform rotary grinding type cleaning on the workpiece 600, and the special-shaped grinding head 300 is in a "cotton stick integrated" bump type, which is similar to an integrated body of numerous "cotton sticks", so that the cleaning efficiency can be improved, and a large amount of manpower can be replaced. Wherein, one "cotton swab" is a grinding head bump 310, as shown in fig. 2 and fig. 3, the grinding head bumps 310 are arranged in a dot matrix, and the grinding head bumps 310 in each row are arranged in a staggered manner, the grinding head bumps 310 include a cylindrical body 311 fixedly connected and an arc body 312 protruding outward toward the surface of the workpiece 600, the grinding head bumps 310 are in an overpressure state when being lowered to be in contact with the surface of the workpiece 600, and can be elastically deformed, and the arc body 312 can be flattened, so that the grinding head bumps 310 are similar to a cylinder, when the special-shaped grinding head 300 performs a rotational motion under the action of the driving member 100, the grinding head bumps 310 perform a circular motion around the rotation axis of the special-shaped grinding head 300, the cleaning range of each grinding head bump 310 is a circular ring, and due to the staggered arrangement of the dot matrix of the grinding head bumps 310, the cleaning ranges of adjacent grinding head bumps 310 are overlapped in a staggered, the grinding head protrusions 310 can achieve full surface contact with the surface of the workpiece 600 without dead angles, so that the shaped grinding head 300 does not have cleaning dead angles when cleaning the surface of the workpiece 600.

In one embodiment, the automatic abrasive cleaning apparatus further comprises a control system connected to the drive member 100 for controlling the lowering distance of the profile grinding heads 300. Wherein a critical value is prestored in the control system, when the descending distance of the special-shaped grinding head 300 is equal to the critical value, the arc-shaped bodies 312 of the grinding head salient points 310 are just flattened, and the grinding head salient points 310 can realize surface contact with the surface of the workpiece 600. In the working process of the automatic grinding and cleaning device, the control system only needs to control the descending distance of the special-shaped grinding head 300 to be larger than the critical value.
