Description

PCBA anti-jamming board conveying track

Technical Field

The utility model relates to a material delivery track especially relates to a PCBA anti-sticking board delivery track who uses in to PCBA course of working, belongs to tool equipment technical field.

Background

A Printed Circuit Board (PCB) is a support for electronic components and is also a carrier for electrical connection of various electronic components. The PCB blank is processed and assembled with various electronic components to obtain a PCBA (Printed Circuit Board Assembly), which is then applied to various electronic devices. In recent years, with the continuous improvement of the technology level and the automation production level, various electronic devices are updated more and more frequently, the PCBA is widely applied in various fields, so that all electronic devices on the market at present include the corresponding PCBA, and in order to meet the increasingly rich functional requirements of the electronic devices, the shape and the processing flow of the PCBA are gradually complicated, and the production standard of the PCBA is increasingly strict.

In PCBA's course of working, need utilize the delivery track to realize PCBA's conveying between each station, and under some complicated operating modes, PCBA need be transported in turn between many delivery tracks, and at this moment, the smooth and easy degree that the delivery track carried to PCBA has just decided whether subsequent PCBA processing can go on smoothly. Most of industrial production enterprises at present aim at the conventional conveying track and structure of the PCBA, namely the PCBA and the conveying track are in hard contact, and the PCBA moves on the conveying track by means of sliding friction between the PCBA and the conveying track. However, it is anticipated that such an operation may be very demanding with respect to the feed angle of the PCBA, and that as long as the feed angle of the PCBA is offset, problems with the PCBA pallet may easily occur. Once the PCBA is jammed in the conveying track, the equipment is shut down and normal processing cannot be completed, and the operation of the whole production line is affected and production accidents are caused seriously. Particularly, when the conveying track is connected with processing equipment like a reflow oven, once the PCBA clamping phenomenon occurs, the PCBA of the whole oven is very easy to scrap.

Therefore, how to put an end to the phenomenon of clamping the PCBA has great significance in improving the production efficiency of processing enterprises. In order to solve the problem of the anti-blocking board, the anti-blocking board can be realized only by a manual inspection mode at the present stage, so that the work of an operator is increased, and the processing enterprise also wastes human resources.
