Universal LCM (liquid crystal module) assembly production line

Abstract

The invention belongs to the technical field of LCM production lines, and particularly relates to a universal LCM assembly production line which comprises an assembly mechanism, a lighting detection mechanism and an appearance detection area. The assembling mechanism comprises a front double-layer main machine frame, an upper-layer assembling conveying line arranged on the front double-layer main machine frame, a lower-layer return line arranged on the front double-layer main machine frame and located below the upper-layer assembling conveying line, and a toothed plate installed on the upper-layer assembling conveying line. The first infrared correlation sensor is arranged on the side of the lower layer return line, the ion fan is installed on the front double-layer main machine frame, the lifter is arranged at the end of the front double-layer main machine frame, and the transition assembly is arranged at the tail end of the front double-layer main machine frame. The whole assembly and detection process of the LCM is completed on the same production line, material carrying between procedures through a transfer robot or manual work is avoided, the carrying risk caused by careless operation is reduced, and the overall assembly yield is increased.

Description

technical field [0001] The invention relates to the technical field of LCM module production line, in particular to a general-purpose LCM module assembly production line. Background technique [0002] LCM module, that is, LCD display module, refers to components that assemble liquid crystal panels, connectors, control and drive circuit boards, optical films, light guide plates, reflectors, backlights, structural parts, etc., dust-proof The requirements are high, the assembly process is numerous, and the process is relatively complicated. As the market demand for large-size LCD modules increases, the design requirements for the assembly production line are relatively increased. If the production line design is unreasonable, it will affect production efficiency and quality. [0003] At present, manual assembly or semi-automatic assembly combining manual and mechanical methods are widely used, which has the following disadvantages: 1) The single-layer production line with conti...

[0002] LCM module, that is, LCD display module, refers to components that assemble liquid crystal panels, connectors, control and drive circuit boards, optical films, light guide plates, reflectors, backlights, structural parts, etc., dust-proof The requirements are high, the assembly process is numerous, and the process is relatively complicated. As the market demand for large-size LCD modules increases, the design requirements for the assembly production line are also relatively increased. If the production line design is not reasonable, it will affect production efficiency and quality.

[0003] At present, manual assembly or semi-automatic assembly combining manual and mechanical methods are widely used, which has the following disadvantages: 1) The single-layer production line with continuous processes occupies a large amount of workshop area; 2) The production line is not continuous, and transfer robots or manual labor are required between processes. When handling materials, since the optical film, light guide plate and liquid crystal panel are all vulnerable parts, damage and dust will seriously affect the display effect and can only be reworked and replaced. In order to improve the current situation, continuous research and development processes are required, with high efficiency and cost-effectiveness. high assembly line
