Printed circuit board smoothness detection apparatus convenient to move

Abstract

The present invention relates to a printed circuit board smoothness detection apparatus convenient to move, comprising a square detection supporting plate, a square detection upper cover plate, supporting bars and a pedestal ; wherein the central section of the upper surface of the detection supporting plate is fixed with four corners of the detection upper cover plate in a spacing and parallel way through bolts, the lower surface of the detection supporting plate is symmetrically fixed with upper end portions of the four parallel supporting bars, the bottom ends of the four supporting bars are fixed on the horizontal pedestal, four corners of the lower surface of the pedestal are provided with universal wheels, the detection supporting plate and the detection upper cover plate are parallel and vertically incline at a certain angle, the lower surface of the square detection upper cover plate is parallelly and fixedly provided with a wear-preventive layer, and the upper surface of the square detection supporting plate is parallelly and fixedly provided with a slip assisting layer. According to the printed circuit board smoothness detection apparatus provided by the invention, the detection supporting plate is inclined, and a gap between the detection supporting plate and the detection upper cover plate only enables a qualified template and a cover plate within the range of allowable error to smoothly pass through, thus a detection method is simple, fast, and accurate in result.

Description

technical field [0001] The invention belongs to the field of auxiliary appliances, in particular to a mobile and convenient printed circuit board smoothness detection device. Background technique [0002] All smart tablet computers need to use flexible printed circuit boards. When making flexible printed circuit boards for tablet computers, since the circuit boards are small and soft, they are usually fixed on the template before post-processing during operation. Usually, the formwork is used repeatedly for a long time. Due to the high use time and frequency, the formwork will be worn out. In addition, it will also be squeezed and bumped during use and transportation. Therefore, the flatness of the formwork will change. At present, there is no detection device for the flatness of the relevant template, which brings inconvenience to production. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and prov...
