Soft bag light inspection method and light inspection machine

Abstract

The invention provides a light inspection method and a light inspection machine for a soft bag, and the method comprises the following steps: clamping the shoulder part of the soft bag to enable the soft bag to be in a vertical state, knocking the surface of the soft bag, clamping the bottom area of the soft bag by adopting a light-transmitting clamp, adopting a backlight source and a side light source to irradiate the bottom area of the soft bag, and detecting a heavy foreign matter in the bottom area of the soft bag; adopting a backlight source and a side light source for conducting cross irradiation on the soft bag body to detect the suspended foreign matter of the soft bag body; adopting a shadowless light source to irradiate the edge area of the soft bag, photographing the edge area of the soft bag in the rotating state and the sudden stop state, and detecting the foreign matter in the edge area of the soft bag; and photographing and detecting black spots of the cover body of the soft bag in the rotating state. According to the all-dimensional dead-corner-free light inspection method, all foreign matters on the side edges, the bottom edges, the cover bodies and the bag bodies of the soft bags can be detected, the omission ratio is reduced, and therefore the detection quality of the foreign matters of the soft bags is greatly improved.

Description

technical field [0001] The invention relates to the field of infusion soft bag inspection, in particular to a soft bag light inspection method and a light inspection machine. Background technique [0002] As the most widely used medical reagents, large infusion products are basically packaged in glass bottles, plastic bottles and soft bags. Among them, soft bags are easy to process and manufacture, low in cost, high in production efficiency, and long in storage. The characteristics of good sealing, convenient use, storage and transportation have been widely used in the packaging of pharmaceutical products. [0003] Existing soft bags such as figure 1 As shown, it is formed by edge fusion welding. The material of the soft bag is plastic. Since the soft bag does not have a relatively regular shape like glass bottles and plastic bottles, and the surface material is soft and has strong adhesion, the edge area and bottom of the soft bag The area is easy to gather foreign matter...
