Problems solved by technology

In the production process of the circuit board, it is necessary to test the inner layer circuit of the inner layer board. The existing inner layer board testing device is mostly manual testing, which is cumbersome and time-consuming to operate, and the production efficiency is low, which is not conducive to large-scale production. Moreover, the existing test device needs to be adjusted when testing circuit boards of various sizes and specifications, and the operation is troublesome.

Abstract

The invention discloses an inner-layer board testing device of a hard circuit board and an implementation method of the inner-layer board testing device. The device is characterized in that two ends of a conveying frame are respectively hinged with an angle adjusting outlet board and an angle adjusting inlet board. According to the invention, the angle adjusting inlet board and the angle adjusting outlet board can easily adjust angles so as to conveniently connect upstream and downstream production lines and optimize the production process; fastening assemblies are arranged on the two sides of the conveying assembly to fix an inner layer plate so as to prevent the problem of testing accuracy caused by shaking of the inner layer plate; a testing assembly comprises a sliding rail, and under driving of the sliding rail, adjustment can be conducted according to the position, sensed by a position sensor, of the inner layer plate, so that an lifting installation block can be automatically moved to the position over the inner layer plate; and a lifting sliding block is fixedly connected with a rotating needle testing end, and a movable testing needle can rotate by an angle, so that an inner-layer circuit on the inner-layer plate of a to-be-tested hard circuit board can be tested more conveniently, multi-angle adjustment can be achieved, the device can adapt to various circuit boards with multiple scales and multiple contacts, and the applicability is higher.

Description

technical field [0001] The invention relates to the technical field of circuit board testing, in particular to an inner layer board testing device of a hard circuit board and an implementation method thereof. Background technique [0002] The circuit board can be called a printed circuit board or a printed circuit board. The circuit board is made of epoxy resin glass fiber cloth laminate material as the circuit board plate, covered with copper foil as the substrate, and the circuit is formed by exposure etching and other techniques. Finally, various Components are arranged on the circuit board by soldering. Due to the lightness and miniaturization of circuit boards, in order to save materials and large-scale standardized production, several small circuit boards are generally combined into a large circuit board through a connecting bridge and supplemented by a frame, referred to as "panel". It is convenient for clamping and component welding in mass production; after the cir...
