Abstract

A method for automatically aligning the pins of a small liquid crystal display glass plate and an IC plate, which is divided into the following steps to achieve alignment: 1. Determine the corresponding relationship between camera coordinates converted into world coordinates through PC control software; 2. Collect standard products The position of the left outer target, the right outer target of the glass plate and the left and right targets of the IC board inside the glass plate; Position correspondence; 4. Actual production, collect the positions of the left and right external targets of the glass plate and the left and right targets of the IC; 5. Calculate the positions of the virtual left and right external targets of the glass plate, and the positions of the left and right external targets of the IC plate According to the calculation results, the electric alignment platform drives the glass plate to automatically move a certain amount to complete the alignment program between the glass plate signal input terminal pins and the IC board pins. The alignment speed of the invention is fast and the alignment is accurate.

Description

technical field [0001] The invention relates to the technical field of manufacturing small liquid crystal display screens (such as liquid crystal display screens of handheld game machines), in particular to an automatic alignment method for pins of a glass plate of a small liquid crystal display screen and an IC board. Background technique [0002] Small liquid crystal displays are widely used in fields such as game consoles and small video players due to their good display effect, thinness, and energy saving. The structure of the small liquid crystal display is mainly a display glass plate (special glass plate for liquid crystal display), a display IC board (integrated circuit board) and other supporting components. When working, the display IC board processes various information and passes multiple output PIN The pins go into the display glass so that the glass display displays images. The position alignment of the PIN pin of the signal input terminal of the glass display...
