Synchronous Tracking Image Acquisition Mechanism of Automatic Light Inspection Machine

Abstract

The invention discloses a synchronous-tracking image capture mechanism of an automatic light inspection machine and belongs to the field of pharmaceutical machinery. The synchronous-tracking image capture mechanism comprises a center shaft (12), a cylindrical rotary connecting piece (10), an upper rotary table (11) and a lower rotary table (6), wherein the center shaft (12) is used for driving a rotary disc of the light inspection machine to rotate, the upper rotary table (11) and the lower rotary table (6) are fixed at upper and lower ends of the cylindrical rotary connecting piece (10) respectively, the rotary connecting piece (10) is sleeved on the outer side of the center shaft (12) through a shaft sleeve connecting piece in a coaxial rotation manner, and image capture devices are arranged on the upper rotary table (11) and the lower rotary table (6). The synchronous-tracking image capture mechanism is characterized in that the rotary connecting piece (10) is connected with a direct-drive rotary motor (9) sleeved on the center shaft (12) through a rotary connecting mechanism, and the direct-drive rotary motor (9) directly drives the cylindrical rotary connecting piece (10) to rotate forward or reversely. The synchronous-tracking image capture mechanism overcomes the defects of large mechanical wear due to gear wear and large errors, and has the advantages of simplicity in assembly and adjustment, excellent stability and the like.

Description

technical field [0001] A synchronous tracking image acquisition mechanism for an automatic light inspection machine belongs to the field of pharmaceutical machinery and equipment, and specifically relates to a synchronous tracking image acquisition mechanism for an automatic light inspection machine where a bottle to be inspected enters a bottle. Background technique [0002] In the field of medical machinery and equipment, the light inspection machine is a special equipment that uses optical imaging and computer to compare images to automatically and intelligently detect the quality of packaged medicine bottles. The computer analyzes the collected image data, judges the quality of the finished medicine bottle, and rejects the unqualified medicine bottle. [0003] The synchronous tracking image acquisition mechanism in the automatic light inspection machine is mainly responsible for tracking and taking pictures of the bottles to be inspected from various angles. Through imag...

Problems solved by technology

In the past, the image acquisition part of the automatic light inspection machine was fixed by the rotating arm. When detecting multiple indicators at the same time, two or more mechanisms needed to cooperate to complete the work. The work efficiency was low and the structure was complicated. The applicant applied in 2012. New type, multiple sets of image acquisition components are fixed at the same time through the turntable, and multiple sets of bottles to be inspected can be detected at the same time, but both the rotating arm and the turntable adopt gear transmission, the reason is to ensure the coaxial rotation of the image acquisition components and the bottles to be inspected , the slewing arm or turntable should be coaxially sleeved on the central shaft, and the central shaft should drive the entire light inspection machine to rotate, so the diameter of the central shaft is very large, which causes the slewing arm or turntable to be sleeved on the central shaft. The diameter is very large , it is very difficult to connect and drive the lower end of the slewing arm or turntable, so at present, it is driven by gear transmission on the outside to drive the slewing arm or turntable to rotate

However, after long-term practice, it has been found that after the image acquisition part has finished shooting a group, it has to quickly turn to the next group to continue shooting. Due to the frequent changes in speed and direction of rotation, the mechanical wear is large, the stability decreases after long-term use, and the error increases. Inaccurate collection affects the quality of drug testing
