Foreign matter detecting device for light inspection machine of hydro-acupuncture ampoule bottles

Abstract

The invention provides a foreign matter detecting device for a light inspection machine of hydro-acupuncture ampoule bottles. The device is characterized by comprising a synchronous following image acquisition device, a mechanical jaw bottle clamping device and a main driving system, wherein the synchronous following image acquisition device is provided with a hollow direct-drive servo motor; the hollow direct-drive servo motor is fixedly connected with a hollow direct-drive servo motor output flange; the hollow direct-drive servo motor output flange is fixedly connected with one ends of at least two revolving arms; at least one revolving arm is provided with backlight mounting bases and camera mounting bases, and the rest of the revolving arms are provided with bottom light source mounting bases and camera mounting bases; backlights are arranged on the backlight mounting bases; bottom light sources are arranged on the bottom light source mounting bases; and cameras are arranged on the camera mounting bases. The cameras, the backlight sources and the bottles to be detected are high in synchronism, so that the image acquisition quality of the cameras is guaranteed, and the detecting precision of the light inspection machine is greatly improved.

Description

technical field [0001] The present invention mainly relates to the field of pharmaceutical machinery and equipment, in particular to a foreign object detection device used in a fully automatic water needle ampoule bottle light inspection machine, which is specially used for the light inspection machine system to realize detection of all substances in the liquid medicine in the water needle ampoule bottle. Foreign matter detection function, the main foreign matter detected are: glass chips, metal aluminum chips, rubber chips, hair, fibers, etc. Background technique [0002] In the field of pharmaceutical machinery and equipment, the automatic liquid medicine bottle intelligent visual inspection system is a fully automatic online inspection device for the quality inspection of ampoules, vials and large infusion bottles on the pharmaceutical production line. It can detect glass debris and metal aluminum on-line. Chips, rubber crumbs, hair, fibers and other foreign matter, can a...

AI Technical Summary

Problems solved by technology

At present, most domestic light inspection machines use cameras and light sources to be installed on different mechanical structures, and are synchronized through mechanical transmission. Due to the limited processing accuracy of parts and errors in structural installation, the synchronization of cameras, light sources, and bottles to be inspected Difficult to guarantee, directly affects the accuracy of foreign object detection

[0006] 2. At present, most of the light inspection machines in China adopt the base and pressure rod structure, the mechanical structure is complicated, and the requirements for the bottle are relatively high.

On the one hand, if the bottle head is defective, such as burrs, scorched heads, etc., it is easy to cause the bottle to break

Difficult to clean if bottle breaks during inspection

On the other hand, the bottles to be inspected are placed on the bottom light source, and they touch and rub against each other, which will also cause scratches on the contact surface

In this way, the light emitted by the bottom light source will be blocked and the intensity will be weakened, which will have a significant impact on the foreign object detection of the product

[0007] 3. Due to the large size and weight of large particles of foreign matter, it is usually difficult to completely leave the bottom of the bottle during the rotation of the bottle

At present, most of the light inspection machines in China adopt the base and pressure rod structure, which will have a certain blind spot for the visual system detection, especially for the detection of large particles of foreign matter at the bottom of the bottle.
