Positioning structure of circuit board

Abstract

The invention discloses a positioning structure of a circuit board. The positioning structure comprises a base plate and a sliding plate which is fixedly arranged on the base plate, wherein a guide rail with a groove is arranged on the base plate; a bracket is fixedly arranged on the sliding plate; a sliding block which is occluded with the guide rail is fixedly arranged at the bottom of the sliding plate; a threaded connector matched with a fine-tuning screw is arranged on a movable plate; a support rod is arranged in the middle of the movable plate and a lining plate is connected onto the supporting rod; a fixing plate is arranged on the lining plate and is connected with a tray; and positioning holes which are arrayed according to a matrix are arranged at the top of the tray. Accordingto the positioning structure disclosed by the invention, the punching positions of a flexible circuit board can be positioned and punched in advance through a matrix positioning structure and an automatic-lifting system, and thus the processing with high precision and high efficiency is realized.

Description

technical field [0001] The invention relates to a circuit board positioning structure, in particular to a positioning structure used on a material table of a flexible circuit board punching machine. Background technique [0002] Flexible circuit board, referred to as soft board or FPC, is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film, with high wiring density and low weight. Light and thin. Mainly used in many products such as mobile phones, notebook computers, PDAs, digital cameras, and LCMs. [0003] At present, with the continuous development and growth of the electronic information industry, the demand for the output of flexible circuit boards is increasing, and the requirements for quality are becoming more and more stringent. Therefore, the requirements for punching machines for processing flexible circuit boards are also increasing. Before punching the circuit board, the punching position of the flexible board must...

[0003] At present, with the continuous development and growth of the electronic information industry, the demand for the output of flexible circuit boards is increasing, and the requirements for quality are becoming more and more stringent. Therefore, the requirements for punching machines for processing flexible circuit boards are also increasing. Before punching the circuit board, the punching position of the flexible board must be adjusted first, so that the alignment can be accurate when punching on the template, so the advance positioning of the circuit board is particularly important. The existing eight-hole circuit board positioning structure includes circuit Board and board, three positioning holes are symmetrically arranged on the two board sides in the length direction of the circuit board, and one positioning hole is respectively provided in the middle of the two board sides in the width direction of the circuit board. This structure has sufficient positioning accuracy, but the operation It is troublesome to look at. The tray and the fixed plate are also fixedly connected and cannot be disassembled at will. Less than the requirements of mechanization, which affects the production efficiency
