Automatic abrasive paper clamping type flexible automatic grinding device

Abstract

The invention discloses an automatic abrasive paper clamping type flexible automatic grinding device. The flexible automatic grinding device comprises a grinding device body, a moving mechanism used for driving the grinding device body to move in a space and an abrasive paper loading and unloading device used for replacing abrasive paper on the grinding device body, wherein the grinding device body and the moving mechanism are fixed by a mounting fixing frame; the grinding device body comprises a spindle motor, an eccentric shaft and a vibration grinding assembly, the eccentric shaft is connected with the driving end of the spindle motor through a coupler, a needle bearing is arranged on an eccentric section of the lower portion of the eccentric shaft, and a follower is connected to the outer ring of the needle bearing in a sleeved mode; and the vibration grinding assembly comprises a grinding plate perpendicular to the axis of the eccentric shaft, clamping assemblies used for fixing the abrasive paper are symmetrically arranged at the two ends of the grinding plate, and the grinding plate is connected with the mounting fixing frame through a damping assembly. The automatic abrasive paper clamping type flexible automatic grinding device is suitable for an automatic production line, and abrasive paper loading and unloading are automatically carried out, so that the machining efficiency is improved, and the cost is saved; and vibration is reduced through the damping assembly, flexible grinding is carried out, and the ground surface is uniform.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing equipment, in particular to a flexible automatic grinding device with automatic clamping of sandpaper. Background technique [0002] In order to ensure the reliability of the fingerprint chip coating process, the chip epoxy resin needs to be polished. [0003] At present, hand-held grinders are mainly used in the market to grind and polish chip epoxy resin to meet coating requirements. The hand-held grinder is a GSS2300 Bosch electric sandpaper machine; the motor shaft is directly connected to the eccentric part, and the eccentric part is installed on the grinding plate, and everyone rotates to drive the grinding plate to vibrate to achieve grinding products. The existing hand-held grinder is not easy to achieve automatic grinding; it is inconvenient to install It is used in automation equipment; manual work is labor-intensive, and loading and unloading sandpaper is also manual loa...
