Description

PCB (printed circuit board) stop structure

Technical Field

The utility model belongs to the technical field of electromechanics, a PCB board only stops structure is related to.

Background

The PCB board passes through different stations in the on-line conveying process to carry out the processing of different processes to it, when arriving appointed station, need scram with accurate processing, however, in order to ensure conveying efficiency, conveying speed can not be too slow again, even if conveying speed is very slow, under the inertial force effect, panel also hardly overcomes inertial force and realizes accurate stopping.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a PCB board only stops structure, the utility model aims to solve the technical problem how ensure that panel stops transport in the course of working.

The purpose of the utility model can be realized by the following technical proposal: a PCB board stopping structure is characterized by comprising an upper support, a lower support, a driving motor, a plurality of upper rollers and a support plate, wherein an upper rotating shaft is fixedly arranged on the upper rollers and is connected with the driving motor, two ends of the upper rotating shaft are respectively connected with the upper support through an upper sleeve, the upper sleeve is rotatably connected with the upper rotating shaft, a gap allowing a PCB board to pass through is formed between the upper rollers and the support plate, a guide cylinder is fixedly arranged on the lower end surface of the support plate, a guide rod is fixedly arranged on the lower support and is inserted in the guide cylinder, a reset spring is sleeved on the guide rod, an installation hole with an opening facing towards the upper sleeve is formed in the upper sleeve, a top block is connected in the installation hole in a sliding mode and is an iron block, an energizing coil is wound on the top block, a tension spring is connected between the top block and the top of the installation hole, the top of the mounting hole is provided with a magnet block, and the electrified coil can repel the magnet block and extend out of the lower part of the mounting hole after being electrified.

The driving motor keeps a normal running state and is acted by the upper roller, the plate moves smoothly on the support plate, when the plate is required to be stopped to be processed, the electrified coil is electrified and repulsed by the magnet block, the ejector block moves downwards and is pressed on the plate, the plate is ensured to be stopped at an accurate position, the ejector block ejects the plate, the inertia force of the plate in running is eliminated, and therefore the plate is ensured not to be driven in the processing process.

In the above-mentioned PCB board stop structure, the upper sleeve is connected with the upper rotating shaft through a bearing.
