Polishing grinding machine for LED ceramic bracket

Abstract

The invention discloses a polishing grinding machine for an LED ceramic bracket. The polishing grinding machine comprises a rack, a workpiece conveying device, a polishing grinding device and a PLC controller. The workpiece conveying device comprises a conveying belt, a conveying roll shaft and a motor. A locating roll shaft is arranged above the conveying belt. The polishing grinding device comprises a vertical pedestal, a drive wheel, a driven wheel, and an abrasive belt. The conveying belt is provided with a pressure sensor. The driven wheel is provided with a lifting drive structure. Moreover, the abrasive belt is provided with an offset sensing switch for sensing a positional deviation of the abrasive belt and a correcting mechanism for pushing and correcting an abrasive belt winding position. The PLC controller is respectively connected with the motor, the pressure sensor, the lifting drive mechanism, the offset sensing switch and the correcting mechanism. The automation degree and the intelligent degree of the polishing grinding machine are increased greatly by automatically sensing a contact pressure between the abrasive belt and a workpiece, automatically sensing the winding position of the abrasive belt, and automatically regulating the contact pressure and the winding position in real time based on the actual conditions, accordingly increasing the machining efficiency and guaranteeing the polishing grinding quality better.

At the same time, it is often caused by artificial Errors make it difficult to obtain a consistent surface finish;

[0003] Later, some automatic polishing machines appeared, for example, a belt polishing machine disclosed in the invention patent document with application number 201410361029.2, which is mainly suitable for flat workpieces, and the workpieces are transported along the conveyor belt, and are subjected to There are many defects in the polishing process of the abrasive belt, for example: during the conveying process of the workpiece on the conveyor belt, it is easy to shift, so that the required polishing surface cannot be polished at one time, which affects the processing efficiency and easily leads to inconsistencies in the effect of the polished surface Bad phenomenon; there are also workpieces (such as LED ceramic brackets) in the process of conveying and polishing, which are very easy to reduce the product quality of the workpiece due to frictional overheating, such as deformation, etc.
