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...

The invention provides a method for obtaining the cutting rate of a printed circuit board. The method for obtaining the cutting rate of a printed circuit board includes; according to the sizes of a plurality of mother boards and the size of a to-be-cut board, calculating an optimal mother board long edge cutting number and an optimal mother board wide edge cutting number corresponding to differentmother board sizes and different placement directions of to-be-cut boards as a selected mother board long edge cutting number and a selected mother board wide edge cutting number by using an approximation algorithm; calculating cutting rates corresponding to different mother board sizes and different placement directions of to-be-cut boards by combining a preset cutting rate calculation formula;selecting The maximum one of the cutting rates corresponding to different mother board sizes and different placement directions of the to-be-cut boards as the optimal cutting rate. the optimal cuttingrate of the printed circuit board can be quickly obtained, so that the layout and wiring design can be more reasonably carried out, the working efficiency is improved, and the production cost is 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...
