Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food and drug packaging machinery, and in particular to a tracking detection device for a lamp inspection machine. BACKGROUND

[0002] The lamp inspection machine can detect internal impurities of opaque or semi-transparent oral liquid bottles, ampoule bottles and large infusion bottles, including detection and identification of various types of foreign matter such as glass chips, metal chips, hair, fibers and black and white blocks. It can also detect the appearance of the container, such as damage, cracks, cap quality and bottle mouth printing quality, and classify and remove unqualified products after detection. The lamp inspection machine rotates the detected object at high speed and then stops by the tracking detection mechanism. The industrial camera continuously takes pictures to collect multiple images. The computer system calculates, analyzes and compares the images to determine whether the detected product is qualified or not, and automatically separates and collects the product.

[0003] As the detection speed of the lamp inspection machine becomes faster, the number of container clamps on the turntable increases, and the diameter of the lamp inspection machine turntable expands. The detection bracket that swings back and forth synchronously with the turntable also needs to be further expanded, the weight increases, the radius of rotation also increases, which leads to a larger swing inertia. The motor may not be able to drive the detection bracket to swing. Therefore, how to reduce the swing inertia of the detection bracket has become a problem that needs to be solved urgently.

[0004] The existing lamp inspection machine sets a bearing between the turntable and the detection bracket. Part of the structure of the bearing is fixedly connected with the detection bracket. Therefore, the weight of this part of the structure is added to the detection bracket, which increases the weight of the detection bracket. In addition, some lamp inspection machines set an arc-shaped guide rail on the rack table surface. A light weight slider is installed on the detection bracket and cooperates with the arc-shaped guide rail for guidance, thereby reducing the weight of the detection bracket. However, since the arc-shaped guide rail is installed on the table surface, it is difficult to ensure that the center of the arc-shaped guide rail is on the rotating shaft of the turntable, which can easily cause jamming and is not convenient to install and debug.
