Device and method for automatically detecting flatness of surfaces of circuit boards

Abstract

The invention discloses a device and method for automatically detecting the flatness of surfaces of circuit boards. The device comprises a detecting platform and a detecting mechanism. The detecting mechanism is arranged on the detecting platform. The detecting platform is provided with a detecting base. The detecting base is provided with a supporting rod, a first clamping block and a slide rod.The first clamping block is fixedly connected with the detecting base. The slide rod is slidingly connected with the detecting base. The detecting base is provided with a first electric push rod. Thefirst electric push rod drives the slide rod to slide on the detecting base. The slide rod is provided with a second clamping block. The method includes the five steps of a, debugging and running; b,detecting of the detecting base; c, clamping of the circuit boards; d, detecting of the circuit boards; and e, screening of the circuit boards. By means of the device and method, the to-be-detected circuit boards can be positioned and fixed, detection precision is improved, meanwhile the detecting base can be adjusted according to the circuit boards with different sizes, and the universality of the detecting base is improved; and by means of the method, the detecting process is optimized, steps are simplified, detecting efficiency is improved, and the detecting precision and detecting effect are improved.

Description

technical field [0001] The invention belongs to the technical field of circuit board detection, and in particular relates to an automatic detection device and method for the surface flatness of a circuit board. Background technique [0002] With the continuous development of the circuit board industry, the electronic components mounted on high-end handheld electronic consumer products are getting smaller and smaller, and the requirements for the flatness of the circuit board surface during the mounting process are getting higher and higher. During the production process of printed circuit boards, factors such as the substrate itself and the obvious asymmetry of the circuit patterns on both sides of the circuit board will affect the flatness of the board surface. Therefore, while doing a good job in the quality control of the production process, the inspection of the flatness of the circuit board before shipment is an indispensable item in the reliability test. The circuit b...

Problems solved by technology

It is inconvenient and difficult to locate the circuit boards in the flatness detection process of the circuit board, which is not conducive to the continuous detection of a large number of circuit boards. At the same time, the detection of a single circuit board will also affect the detection accuracy
