Double-station double-rotation type plate glass automatic feeding and discharging device and method thereof

Abstract

The invention relates to the technical field of CNC machine tools, in particular to a double-station double-rotation type plate glass automatic feeding and discharging device and a method thereof. The double-station double-rotation type plate glass automatic feeding and discharging device structurally comprises an engraving machine box, a truss mechanical arm, a connecting plate, a base, a working area, a lifting type pneumatic clamp, a universal material frame, a rotating center shaft and a rotary suction cup mechanism; the engraving machine box is installed at the upper end of the base, the lifting type pneumatic clamp is arranged on the base, the clamp on the device drives a pushing air cylinder through a supporting linear rail to push a lifting air cylinder towards a jig, a short clamping block and a positioning long clamping block complete positioning work on the position of an object on the jig, and the clamping long clamping block and an ejector rod complete clamping and limiting work on the object on the jig, so that the positioning and clamping work on the object is accurately completed, wherein the supporting linear rail is installed at the bottom of the lifting air cylinder, the linear motion precision of the air cylinder in the return stroke process is guaranteed, a gap error of a guide shaft of a cylinder rod of the air cylinder is made up, and the motion precision of the clamping blocks is greatly improved.

Description

technical field [0001] The invention relates to the technical field of CNC machine tools, in particular to a double-station double-rotation automatic loading and unloading device for plate glass and a method thereof. Background technique [0002] CNC machine tool solves complex, precise, small batch and multi-variety parts processing problems well. It is a flexible and high-efficiency automatic machine tool. It represents the development direction of modern machine tool control technology. It is a typical mechanical and electrical integration. However, its existing CNC machine tools have the following defects: [0003] 1. The pneumatic clamp on the machine tool is relatively inaccurate in positioning and clamping objects. The clamping blocks on the clamp can only be clamped in a forward and backward manner, and its linear motion accuracy is low, and the clamping efficiency is poor; [0004] 2. It is difficult to flexibly adjust the position of the round bead card slot on th...

AI Technical Summary

Problems solved by technology

[0003] 1. The pneumatic clamp on the machine tool is relatively inaccurate in positioning and clamping objects. The clamping blocks on the clamp can only be clamped in a forward and backward manner, and its linear motion accuracy is low, and the clamping efficiency is poor;

[0004] 2. It is difficult to flexibly adjust the position of the round bead card slot on the frame for the product used for the front and rear cover plates of the mobile phone. Different types of covers cannot be inserted straight and smoothly through the bead card slot on the material rack and disassembled. It is more troublesome. It is necessary to disassemble the whole material rack, replace the worn parts of the card slot and then reassemble it. Maintenance is time-consuming and laborious;

[0005] 3. When picking and unloading materials, it is generally performed by multiple single stations, which has low efficiency and poor stability of picking and unloading materials, and it is difficult to effectively clean the liquid or debris on the surface of the product when picking and placing, and the adsorption is more difficult. Unstable, the safety of the fixture is reduced
