Description

Non-connecting rib routing tool Technical Field The utility model relates to the technical field of printed circuit board processing, in particular to a routing tool without connecting ribs. Background In the field of Printed Circuit Board (PCB) manufacturing, the reliability of imposition design and board separation process directly affects product accuracy and yield. In traditional PCB makeup design, mechanical connection is realized through the connecting rib among each small unit, and this structure can strengthen the integral strength of makeup, can avoid the fracture risk in transportation and the paster in-process again. However, with the development of the electronic products toward light and thin, part of application scenes require that the units are completely free of physical connection after being split, i.e. a design without connecting ribs is adopted. Although the design can simplify the later plate separating process, the technical defect is obvious in the plate milling process, namely, due to the lack of the fixing function of the connecting ribs, the mechanical stress generated when the high-speed rotating milling cutter cuts the plate is easy to cause the displacement or deformation of the PCB, so that the problems of over-tolerance in size, increased edge burrs and the like are caused. Particularly in the scene of high precision requirement, such as photoelectric plate printed plug alignment or mechanical blind hole positioning, the functional failure can be caused by the slight size deviation. In the prior art, deformation can be relieved by optimizing milling parameters (such as adjusting rotating speed and feeding speed) or adopting a stepped cutting process, but plate deflection caused by a structure without connecting ribs cannot be fundamentally eliminated, and in addition, the traditional scheme of additionally adding a compressing structure has great limitation, because the compressing mechanism is difficult to be added to compress each PCB unit, the problem is solved by continuing a milling tool without connecting ribs. Disclosure of utility model The utility model mainly aims to provide a connecting rib-free routing tool, a strip-shaped clamping groove can accommodate printed circuit board units in the same row, the printed circuit board units are clamped in corresponding positioning grooves, meanwhile, connecting ribs between the printed circuit board units in the same row are positioned in through grooves, and therefore boards without connecting ribs in different rows are placed in the grooves. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a no connecting rib gong frock, includes the base, the cell body that holds printed circuit board has been seted up at the base top, a plurality of bar draw-in groove has been seted up to the bottom in the cell body, a plurality of have in the bar draw-in groove a plurality of with printed circuit board unit shape assorted constant head tank, same have the division board between a plurality of constant head tank in the bar draw-in groove, division board top has been seted up and has been connect muscle shape assorted logical groove with printed circuit board. Further, a positioning hole is formed in the periphery of the bottom in the groove body, and a positioning rod is inserted into the positioning hole.
