Autorotation drive device for automatic lamp inspection machine

Abstract

An autorotation drive device for an automatic light inspection machine, which includes a driving pulley, an autorotation drive mechanism, an upper transmission belt, a lower transmission belt, and two sets of transmission pulleys with different heights. The output ends are connected, and each drive pulley set includes a pair of drive pulleys with the same height, the upper drive belt is wound on the upper part of the drive pulley and one drive pulley set, and the lower drive belt is wound on the drive pulley The lower part of the pulley and another drive pulley set. The invention is a self-rotating driving device for an automatic lamp inspection machine, which has a simple and compact structure, low cost, high stability, and can improve the detection accuracy of an image 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
