The full-automatic LCD glass surface mounting machine is provided with a servo motor and a PLC and successively comprises a loading device, a first transmission belt, a glass feeding device, a first surface mounting platform, a first surface mounting machine, a second surface mounting platform, a second surface mounting machine, a transport adsorption device and a second transmission belt according to a passing-through sequence of glass chips; the particular running process of full-automatic LCD glass surface mounting machine includes the steps that the loading device transports the glass chips to the first transmission belt, the glass feeding device transports the glass chips to the first surface mounting platform, the first surface mounting platform completes the surface mounting and transports the glass chips to the second surface mounting platform, and the second surface mounting platform completes the surface mounting and transports the glass chips to the second transmission belt through the transport adsorption device. According to the full-automatic LCD glass surface mounting machine, the PLC is adopted to take control, and the accurate and rapid attachment between base chips and substrates is achieved through the servo motor, ball screws, a linear guide rail, an auxiliary pneumatic system, a vision sensor and a mechanical positioning device; the full-automatic LCD glass surface mounting machine is safe and reliable in running, convenient to operate, accurate in positioning and high in attachment accuracy, and the production efficiency is greatly improved.

Description

technical field [0001] The present invention relates to a placement machine, more specifically, relates to a fully automatic LCD glass placement machine. Background technique [0002] In the structure of the liquid crystal display, the polarizer is one of the key components that affect the display effect of the display. It is used to realize the polarization and detection of natural light. The attachment of the polarizer to the liquid crystal display has also become an important part of its post-processing procedure. [0003] The polarizer mounter is an important equipment in the LCD production process. It separates the polarizer from its protective film, and at the same time sends the glass substrate to the placement station, and then quickly and accurately attaches the polarizer to the glass substrate. At present, most of the LCD polarizer placement machines produced in China are semi-automatic, and operators need to manually load and unload materials. The polarizer is sup...

AI Technical Summary

Problems solved by technology

At present, most of the LCD polarizer placement machines produced in China are semi-automatic, and operators need to manually load and unload materials. The polarizer is supplied in multiple pieces at a time, and the glass substrate is manually loaded on a single piece, and manually unloaded after the placement is completed. This method There are certain defects: (1) The degree of automation is low, and professional operators are required to complete the operation, so the production cost is high; (2) Manual feeding is positioned by the vacuum nozzle to push the glass, resulting in a gap between the vacuum nozzle and the negative pressure pump. The connecting pipe between them is easy to wear during the moving process, which eventually reduces the suction force of the vacuum nozzle; (3) The pick-up box for placing glass pieces is generally a fixed template, which requires a new template when changing glass pieces of different sizes. Time-consuming

[0005] However, the above-mentioned semi-automatic attaching machine has a low degree of automation and relies on manual turning over of the glass substrate during the attaching process. When turning over manually, excessive force may cause damage to the glass substrate, and the work efficiency is low. low, waste of manpower
