Printed circuit board smoothness detection apparatus with adjustable height

Abstract

The invention relates to a printed circuit board smoothness detection apparatus with the adjustable height. The detection apparatus comprises a square detection support plate, a square detection upper cover plate, support rods, and a pedestal. The four corners of the detection upper cover plate are fixedly installed at the middle part of the upper surface of the detection support plate at intervals in parallel by bolts; end portions of upper ends of the four parallel support rods are installed at the lower surface of the detection support plate symmetrically and fixedly; and the bottom ends of the two support rods arranged at the front end are fixedly installed on the horizontal pedestal. The detection support plate and the detection upper cover plate are parallel to each other and the detection support plate is arranged obliquely at a certain angle. The spacing distance between the detection support plate and the detection upper cover plate is obtained by adding the thickness of the circuit board to a maximum deformation value. An anti-wearing layer is fixedly installed on the lower surface of the square detection upper cover plate in parallel; and a slip assisting layer is fixedly installed on the upper surface of the square detection support plate. According to the smoothness detection apparatus provided by the invention, the detection support plate is arranged obliquely. The gap between the detection support plate and the detection upper cover plate enables a qualified template and a cover plate with the error within an allowable error range to pass through the gap smoothly but an unqualified product can not pass through the gap. The detection method is simple and is implemented rapidly; and the result is accurate.

Description

technical field [0001] The invention belongs to the field of auxiliary appliances, in particular to a height-adjustable 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 provide ...
