Abstract
The invention relates to a device for preventing a printed circuit board from being clamped in the press fit process of a ground edge. The device comprises a base, a stand column, a cross beam, a left installation column, a right installation column, an installation shaft and an idler wheel, wherein the stand column is fixed to the upper surface of the base; the cross beam is fixed to the upper end of the stand column; the left installation column is fixed to the left end of the cross beam; the right installation column is fixed to the right end of the cross beam; the installation shaft is fixed between the upper end of the left installation column and the upper end of the right installation column and is rotationally provided with the idler wheel; the upper end of the idler wheel is higher than the upper end of the left installation column and the upper end of the right installation column. The device is simple in structure, convenient to manufacture and flexible to install, can effectively support the printed circuit board when the printed circuit board enters an edge grinding machine, and reduces the clamping rate of the printed circuit board.
Description
Technical field
The present invention relates to a kind of device that can prevent printed circuit board (PCB) clamp when pressing edging, the invention belongs to PCB mechanical field.
Background technology
Printed circuit board (PCB) is as the core component of control element, in the development history of more than 100 years, printed circuit board (PCB) (i.e. PCB) is in function, the aspect such as size and production cost experienced by very large change, in recent years by it, integrated circuit is constantly miniaturized, the raising of the day by day complicated and performance of electronic product function, constantly rise as the density of the printed substrate of electronic product heart and the frequency during being correlated with, traditional printed panel can not meet existing requirement, particularly in the high frequency of space flight and aviation lamp field Signal transmissions, digitlization, densification and high-precision refinement, impel the fast development of HDI (High Density Interconnection) high density interconnecting board, high density printed panel adopts Stripline, the multiple stratification design of Microstrip, and adopt low-k, the insulating materials of low attenuation rate, coordinate miniaturization and the array of electronic component structure dress, wiring board improves constantly density with adaption demand, BGA (Ball Grid Array), CSP (Chip Scale Package), the appearance of the modularities such as DCA (Direct Chip Attachment), more printed circuit board (PCB) is pushed to unprecedented high density boundary, drive the fast development of thin plate thus.
In the transition from the old to the new phase of industry, the process capability of legacy equipment has not reached the requirement of producing thin plate far away, the modes such as band plate must be adopted to transmit, otherwise can the problems such as clamp be brought, under whole industrial chain overall situation, produce light, thin, short, little PCB has become trend and trend, each equipment process capability is also drawn close to production thin plate, brown line process capability can accomplish 2mil, outer pre-treatment 3mil etc., the edging line of pressing post processing, the process capability of traditional mode of production slab equipment is at 20mil, newly enter equipment process capability and can reach 4mil, but, thin plate is dragging for limit and is carrying in turnover and plate putting machine suction disc process the bending had in various degree, have the final say simultaneously and also can cause edges of boards prying, after edging, still likely occur that clamp is abnormal, bring the quality problem that plate damages.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the device that can prevent printed circuit board (PCB) clamp when pressing edging that a kind of structure is simple, easily manufactured, can stop printed circuit card plate problem is provided.
According to technical scheme provided by the invention, the described device that can prevent printed circuit board (PCB) clamp when pressing edging, it comprises base, column, crossbeam, left side erection column, right side erection column, installation shaft and roller; Column is fixed with at the upper surface of base, crossbeam is fixed with in the upper end of column, left side erection column is fixed with in the left part of crossbeam, right side erection column is fixed with in the right part of crossbeam, installation shaft is fixed with between the upper end of left side erection column and the upper end of right side erection column, be rotatablely equipped with roller on the mounting shaft, the upper end of roller is higher than the upper end of left side erection column and right side erection column.
Base offers fixing hole.
Structure of the present invention is simple, easily manufactured, flexible for installation, and the present invention can enter between edge polisher at printed circuit board (PCB) provides effective twelve Earthly Branches to support, and reduces the clamp rate of printed circuit board (PCB).
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is right view of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Should can prevent the device of printed circuit board (PCB) clamp when pressing edging, it comprises base 1, column 2, crossbeam 3, left side erection column 4, right side erection column 5, installation shaft 6 and roller 7; Column 2 is fixed with at the upper surface of base 1, crossbeam 3 is fixed with in the upper end of column 2, left side erection column 4 is fixed with in the left part of crossbeam 3, right side erection column 5 is fixed with in the right part of crossbeam 3, installation shaft 6 is fixed with between the upper end of left side erection column 4 and the upper end of right side erection column 5, installation shaft 6 is rotatablely equipped with roller 7, and the upper end of roller 7 is higher than the upper end of left side erection column 4 and right side erection column 5.
Base 1 offers fixing hole 1.1.
The present invention in use, be arranged on the porch of edge polisher, inside and outside both sides respectively install one, thin plate puts plate by plate putting machine sucker, edging section is entered through edge polisher clappers section, undertaking is supported by roller 7 of the present invention enter rotating disk after having ground before, conveying roller is entered after accepting conveying, avoid printed circuit board spring to stick up and can not the clamp caused be carried abnormal by contact roller smoothly, printed circuit board (PCB) half-twist under rotating disk enters second segment edging, need increase device of the present invention equally and be used for improving clamp extremely.
