The invention discloses a method for automatically aligning pins of a small liquid crystal display board plate and an IC board. Aligning is achieved through the following steps that 1, the corresponding relationship of converting of camera coordinates into world coordinates is determined through PC control software; 2, the positions of a left outer target and a right outer target of the standard product glass board and left and right targets, in the glass board, of the IC board are collected; 3, the corresponding relationship of the positions of the left outer target and the right outer targetof the standard product glass board and the left and right targets of the IC board are calculated; 4, actual production is conducted, specifically, the positions of the left outer target and the right outer target of the glass board and the left and right targets of the IC board are collected; and 5, the positions of a virtual left outer target and right outer target of the glass board, and the offset of the virtual left outer target and right outer target to the left and right targets of the IC board are calculated, according to the calculation results, calculation control software transmitsthe calculated offset, needed for aligning of the glass board signal input end pins and the pins of the IC board, of an electric aligning platform to the electric aligning platform, and the electricaligning platform drives the glass board to automatically move by a certain amount to complete the aligning program of the glass board signal input end pins and the pins of the IC board. The aligningspeed is high, and aligning 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...
