Abstract

The invention relates to a printed circuit board (PCB) locating device which comprises a motor. The motor is fixedly installed on a speed reducer, the speed reducer is fixedly installed on a base seat, a big chain wheel is installed on an output shaft of the speed reducer, a small chain wheel is installed on a transmission shaft, the transmission shaft penetrates through conveying chain wheels and is connected with a guide rail, the conveying chain wheels are arranged at two ends of conveying chains, the conveying chain wheels are installed in grooves on the side faces of the guide rail, PCB locating rods and PCB supporting rods are fixedly welded on the side faces of the conveying chains, each set comprises two PCB locating rods, and the PCB supporting rods are welded between every two sets of the PCB locating rods, threads are formed in vertical portions of the PCB locating rods, two sets of holes are formed in two sides of a to-be-welded PCB, the two sets of holes are installed on the PCB locating rods and are fastened by clamp nuts, guide rail sliding blocks are fixed on a support and are connected with the guide rail, a hand wheel is installed on a guide rail lead screw, and the guide rail lead screw penetrates through fixing parts which are welded below the guide rail. The PCB locating device has the advantages of being simple in structure and easy to achieve, and adjusting of width of the PCB locating device is convenient.

Description

technical field [0001] The invention relates to a PCB positioning device. Background technique [0002] In the selective wave soldering machine, the PCB (printed circuit board) needs to run smoothly along the direction of supply and demand, and because the size of each batch of PCB boards that need to be selectively soldered is generally different, so at the same time, the transmission mechanism needs to be able to change according to the size of the PCB board Make any adjustments. In the prior art, the structure of the PCB positioning device is complex, and the width adjustment system of the transmission system is either absent or the adjustment range is small, which cannot meet the production requirements. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a PCB positioning device, which has a simple structure, is easy to implement, and is convenient for width adjus...
