Problems solved by technology

[0004] In view of a series of problems in traditional FPC wiring, production companies have extensively employed experienced operators to reduce the occurrence of errors, but employing experienced operators means increasing the cost of personnel, and this method is still Manual operation is the main method. Compared with automated production, the efficiency is still very low, which is not conducive to mass and rapid production.

Embodiment

[0037] like Figure 1-2 As shown, the present invention provides an FPC-based row-optimized keyboard automatic routing algorithm, comprising the following steps:

[0038] (1) Preparation stage: Manually read the content of the drawing, and according to the content of the drawing, determine the key position, PIN interface and channel to create a logical structure for computer identification.

[0039] Further, the preparation stage refers to creating a logical structure recognized by the computer for the power PIN interface, key position and channel in the keyboard creation according to the actual keyboard properties.

[0040] It should be noted that before wiring, the layout of the drawings to be studied should be studied first. When laying out, consideration should be given to facilitating signal flow, reducing the amount and shortening the leads and connections between components.

[0041] (2) Create node distribution: Create key node distribution by row, and divide logical ...

Abstract

The invention relates to the technical field of industrial control, in particular to a row optimization keyboard automatic wiring algorithm based on an FPC. Comprising the following steps: (1) a preparation stage: manually reading drawing content, and determining a key position, a PIN interface and a channel according to the drawing content to create a logic structure identified by a computer; (2) creating node distribution: creating key node distribution according to rows, and dividing logic coordinates for each node; (3) grouping: according to a keyboard wiring rule, each PIN interface node is connected with n fixed key position nodes in a keyboard, and according to local shortest path wiring, a row optimization algorithm is adopted to optimally solve the local shortest path wiring; and (5) automatic wiring of the whole FPC keyboard: the method provided by the invention has the advantages of high efficiency, low cost and high automation degree, automatic wiring of the FPC circuit board can be realized by applying the method, manual operation is reduced, the wiring efficiency is improved, the whole wiring is convenient and reliable, and the method can be applied to production of the FPC circuit board.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to an FPC-based row-optimized keyboard automatic wiring algorithm. Background technique [0002] At present, with the rapid development and wide application of the flexible circuit board (FPC) industry, the automation and intelligence level of the entire industry is improving year by year, and the wiring design of the flexible circuit board is one of the most important links in the manufacturing process. The demand for industrialization has become increasingly urgent, and has gradually become a research hotspot in this industry, and it is also the most urgent core problem to be solved. [0003] The traditional FPC wiring is basically done manually, and there are many shortcomings and deficiencies, such as: long wiring cycle, low efficiency, time-consuming and labor-intensive, and the layout line adjustment is not convenient enough, and the link statistics function is weak...
