Platform for manufacturing liquid crystal display device and method for examining exogenous impurity on platform

Abstract

The invention discloses a manufacturing machine platform of liquid crystal display (LCD) elements and a method for checking the manufacturing machine platform. The manufacturing machine platform at least comprises a platform, a material supply component, a film forming component and a reflection type sensing component. The platform carries a base plate of the LCD elements in a mobile way, and thematerial supply component is arranged above the platform. The film forming component is arranged above the platform and positioned at one side of the material supply component; a polyemid material can be transferred to the film forming component from the material supply component, and then printed on the base plate in a transferring way from the film forming component to form polyemid. The reflection type sensing component is arranged at the side of the platform to detect the surface of the platform; wherein, a first light beam emitted by the reflection type sensing component has first strength, a second light beam which is received after reflection has second strength; whether foreign matter exists on the platform can be known by comparing the first strength and the second strength. Therefore, meaningless manufacturing cost caused by scratching or stabbing printing relief blocks such as APR version can be avoided being added.

Description

technical field [0001] The present invention relates to a manufacturing machine and a method for checking whether there are foreign objects in the machine, and in particular to a manufacturing machine for forming an alignment film of a liquid crystal display element, and inspecting the manufacturing machine for A liquid crystal display element manufacturing machine and a method for checking foreign matter on the platform for whether there are foreign objects on the surface of the platform carrying the substrate. Background technique [0002] Liquid Crystal Display (LCD) has been widely used in recent years because of its thin size, light weight, low power consumption, and no radiation pollution. Its application products include small-sized portable information products such as personal digital assistants (PDA), general-sized notebook computers or desktop LCD screens. Large-size application products, such as 30-40 o'clock LCD TVs, are also gradually being valued and occupy a...

AI Technical Summary

Problems solved by technology

Since the distance between the platform used to carry the substrate in the manufacturing machine and the APR plate for transfer printing is very close, if there are foreign objects such as fragments remaining on the platform, the fragments will adhere to the APR plate when the platform moves and cause stab wounds or Scratched, at which point the APR version is no longer usable and must be scrapped

In addition, once the APR plate sticks to the fragments and causes punctures or scratches, this plate must be removed to remove the fragments and then confirm, while the machine part must wait for another APR plate to be cleaned and installed before restarting the line

Therefore, the damage of the APR plate not only causes money loss, but also wastes a lot of man-hours and manpower.
