Problems solved by technology

[0003] Weaknesses of the existing technology: every time machining is changed, no matter whether it is a new product or an old product, it is necessary to re-drill the positioning hole on the positioning plate
The consequences of repeatedly drilling positioning holes on a positioning plate: Sometimes the position of the positioning hole just conflicts with other existing positioning holes, resulting in the failure of this positioning hole and re-drilling. If there are multiple new positioning holes and old positioning holes "Crash" will cause the positioning board to be scrapped in advance
Drilling pilot holes multiple times wasted a lot of time

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] With reference to the accompanying drawings, the present invention includes booting ready 1 and finishing work 10, between the described booting ready 1 and finishing working 10 steps, at first is to manually input the printed circuit board number 2, and the computer of the CNC machine tool automatically searches the database to execute the step of judging whether it exists 3, and display "Yes" or "No" on the screen, the operator chooses to perform the following three steps according to the "Yes" or "No" displayed on the screen: processing the next batch 8, processing new varieties 9 And whether to increase 11, when selecting "no" of processing new variety 9, execute the step of finishing work 10 to close the machine tool.

[0014] Described step judges whether existence 3 is the step after being " yes " and is: display printed circuit board positionin...

Abstract

The invention discloses a positioning method for machining printed circuit boards, comprising a start ready (1) and an end process (10), wherein between the start ready (1) and the end process (10), the method comprises: manually inputting a printed circuit board serial number (2), using a digit control machine computer to automatically search a database to judge if there is the operation of the step (3) and display 'yes' or 'no' on a screen, operating following three selection steps according to the contents displayed on the screen as processing a next batch (8), processing a new kind (9) and increase selection (11), executing the end process (10) to turn off the machine when users selects the 'no' item of the processing new kind item (9). The invention stores the coordinates of the positioning holes of a special printed circuit board on a special positioning board in a digit control machine database, only needs one setting to attain repeated distribution, thereby saving the drillingtime of positioning holes and saving positioning boards.

Description

technical field [0001] The invention relates to a positioning method for machining printed circuit boards, which can shorten processing time and save positioning plates when drilling and milling printed circuit boards. Background technique [0002] At present, when CNC machine tools are used to drill and mill printed circuit boards, thick backing plates are generally used as positioning plates for machining. The steps are: install the positioning plate, drill 3 positioning pin holes on the positioning plate, install and position The pins are inserted into the positioning holes, and multiple printed circuit boards to be processed are simultaneously set on the positioning pins, and then machined. In practical applications, a positioning board can provide positioning holes for installing positioning pins for printed circuit boards of multiple specifications. [0003] The weak point of prior art: every time machining changes kind, no matter be new product or old product, all ne...
