Abstract

The invention discloses elastic body strain area sandblasting polishing equipment of a sensor, and relates to the field of manufacturing of weighing sensors. The polishing equipment comprises a workpiece conveying device, a sandblasting bin, a sandblasting gun, a PLC (programmable logic controller) and a workpiece retaining clip for carrying a workpiece, wherein the workpiece conveying device runs through a workpiece feed port and a workpiece discharge port of the sandblasting bin; a travel switch is arranged at a side edge of the workpiece conveying device; positioning concave and convex holes are intermittently formed in a side wall of the workpiece retaining clip and correspond to the position of the travel switch; a first input end of the PLC is connected with an output end of the travel switch; a second output end of the PLC is connected with a control input end of the workpiece conveying device; and a third output end of the PLC is connected with a control input end of the sandblasting gun. The invention solves the problem that the prior art, which is not provided with the retaining clip and a positioning device, cannot achieve sandblasting operation at a specific position of a workpiece; and the technical scheme can effectively improve the strain area sandblasting polishing efficiency and avoid abnormal polishing of other areas at the same time, and is high in automation degree.

Description

technical field

[0001] The invention relates to the field of sandblasting equipment, in particular to a sandblasting and grinding equipment for elastic body strain regions of sensors. Background technique

[0002] In the load cell technology, the resistance strain gauge is pasted on the elastic element so that the other party knows that it is firmly combined as a whole. The basis is that the elastic element patch must have a surface roughness that meets the adhesion requirements, so that it can be removed. The bonding area can also activate the surface, which is conducive to the infiltration of strained adhesives. Therefore, before pasting the strain gauge, it is necessary to perform a grinding process on the bonded area of ​​the elastic strain gauge.

[0003] The existing grinding process is mainly divided into two types, one is manual grinding, that is, grinding is performed manually through sandpaper. Another way is artificial sandblasting, that is, the operator holds a...
