Embodiment Construction
[0044] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.
[0045] see figure 1 , the present invention provides a method for obtaining a printed circuit board cutting rate, comprising the steps of:
[0046] Step S1, providing a plurality of mother board sizes and board sizes to be cut. Each motherboard dimension includes motherboard length and motherboard width. The size of the board to be cut includes the length of the board to be cut and the width of the board to be cut.
[0047]Specifically, in step S3 of the present invention, three motherboard sizes are provided, the motherboard lengths of the three motherboard sizes are all 1230mm, and the motherboard widths of the three motherboard sizes are 927mm, 1030mm and 1079mm respectively.
[0048] Step S2, selecting one of the multiple motherboard si...

A method for obtaining a cutting rate of a printed circuit board, comprising: according to multiple mother board sizes and the size of a board to be cut, by using an approximation algorithm, calculating an optimal mother board long edge cutting number and an optimal mother board wide edge cutting number corresponding to different mother board sizes and different placement directions of the board to be cut as a selected mother board long edge cutting number and a selected mother board wide edge cutting number; then calculating cutting rates corresponding to the different mother board sizes and the different placement directions of the board to be cut by combining a preset cutting rate calculation formula; and selecting a maximum one among the cutting rates corresponding to the different mother board sizes and the different placement directions of the board to be cut as an optimal cutting rate. Therefore, the optimal cutting rate of the printed circuit board can be quickly obtained, so that the layout and wiring design can be performed more reasonably, the working efficiency is improved, and production costs are reduced.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a method for obtaining the cutting rate of a printed circuit board. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass mother plates, control the liquid crystal molecules to change direction by electrifying or not, and refract the light from...
