Autorotation driving device for automatic light inspection machine

Abstract

The invention relates to an autorotation driving device for an automatic light inspection machine. The autorotation driving device comprises a driving belt wheel, an autorotation driving mechanism, upper transmission belts, lower transmission belts and two transmission belt wheel groups with different heights, wherein the driving belt wheel is connected with the output end of the autorotation driving mechanism, each transmission belt wheel group comprises a pair of transmission belt wheels with equal height, the upper transmission belts are winded on the upper part of the driving belt wheel and on one transmission belt wheel group, and the lower transmission belts are winded on the lower part of the driving belt wheel and on the other transmission belt wheel group. The invention is the autorotation driving device for the automatic light inspection machine which has the advantages of simple and compact structure, low cost and high stability and can increase the inspection accuracy of animage acquisition device.

Description

technical field [0001] The invention mainly relates to the field of pharmaceutical machinery and equipment, in particular to an autorotation drive device for an automatic light inspection machine. Background technique [0002] In the field of pharmaceutical machinery and equipment, the light inspection machine is a series of special equipment that uses optical imaging and computer image comparison principles to automatically and intelligently detect the quality of packaged liquid medicines. The computer analyzes the collected image data, judges the quality of the liquid medicine, draws a conclusion and directs the rejection swing arm mechanism on the light inspection machine to reject unqualified medicine bottles. [0003] In the existing light inspection machine, the packaged liquid drugs (such as ampoules filled with liquid medicine, etc.) will be sent to the light inspection plate in turn to complete the detection of foreign objects in the liquid medicine contained in the...

Problems solved by technology

[0005] The deficiencies in the existing structure are: 1. Since the arrangement density of the rotation axes on the light inspection panel is very large, the distance between adjacent rotation axes is very short. When the belt is close to the rotation shaft pulley, due to the size error of the rotation shaft pulley, the efficiency of ordinary transmission is not good, the stability is poor, and the rotation of adjacent rotation shafts is often inconsistent, and the detection accuracy cannot be guaranteed; in order to avoid the above phenomenon, adopt The staggered assembly of pulleys on adjacent rotation shafts is achieved, the interval between pulleys on the same layer is increased, and the risk of pulleys being overhead is reduced

2. During the detection process, when the image acquisition device detects two adjacent bottles to be detected, the speeds of the two bottles to be detected when they reach the detected point are inconsistent, resulting in inconsistent rotation of the liquid medicine in the medicine bottle, thereby affecting the detection accuracy

However, the existing swing arm brake mechanism makes the high-speed rotating bottle unable to stop in the shortest time

In addition, the "swing arm" brake mechanism brakes the rotation axis that drives the bottle to rotate on one side, which is a unilateral brake. Under the influence of momentum, it is easy to make the bottle unable to maintain a balanced state, eccentric or unstable. And the braking force is small, it is definitely not as good as bilateral braking, which will affect image acquisition
