Description

Target drilling equipment

The target drilling equipment of the present invention relates to a target hole drilling equipment in the circuit board manufacturing process, especially those in the technical field that do not need to use a conventional carrier board and can simplify the processing flow.

Printed circuit board (PCB) is an essential part of various electronic products, and its production process is extremely complicated and complicated. Take the conventional circuit board to drill the target hole, as shown in the first picture. In order to prevent the PCB board 91 from directly rubbing against the work table surface when moving, causing scratches on the surface of the PCB board 91, a bearing board 92 is set up on the moving mechanism to support the PCB board 91, and the PCB board 91 and the bearing board 92 move together when moving. , Through the interval of the carrying plate 92, the PCB board 91 will not rub against the work surface to avoid scratches. Using the interval of the carrier board 92, although the problem of scratches on the PCB board 91 is solved, it also causes the accumulation of tolerances. In order to avoid the flatness of the carrier board 92 itself and the uneven thickness of each area, affecting the drilling accuracy, Therefore, it is necessary to drill a square-shaped hole 93 on the bearing plate 92 in the opposite area where the target hole is to be drilled. The size of the square-shaped hole 93 must be large enough to allow the "lower reference small raised surface" to pass through. This allows the "lower reference small lifting surface" to directly support the PCB board 91 to improve the drilling accuracy. But its disadvantage is that every time PCB of different size is produced For the board 91, one area of square-shaped holes 93 must be drilled, but customers have to produce multiple (or several) PCB boards 91 of different sizes every day, which seriously affects the output, and the area of square-like holes 93 becomes more After that, the carrier board 92 must be updated (consumables are formed). Due to the uneven flatness and thickness of the bearing plate 92 itself, the vertical angle difference between the PCB board 91 placed on it and the drill shaft 94 is caused and the "lower reference small raised surface" is higher than or It is lower than the "carrying plate 92", which causes the target hole to be drilled to be offset, which affects the drilling accuracy and roundness. In order to reduce this influence, when switching to produce PCB boards 91 of different sizes each time, in addition to drilling the square-like holes 93, the fixture board must be used to drill multiple holes in this area for comparison to correct the error value; Quite troublesome and inconvenient, and indirectly reduces efficiency and productivity.

The inventor believes that the use of the carrier plate in the conventional manufacturing process greatly limits the possibility of simplification of the process and also hinders cost reduction; especially in order to improve accuracy and compensate for errors, the required drilling calibration procedures are more It is not conducive to increasing production capacity. Therefore, the inventors will find a way to solve the problem, and eventually there will be an invention of this case. It is hoped that through the proposal of this case, the existing shortcomings can be improved and the industry can be upgraded and improved.
