TECHNICAL FIELD

[0001] The present application relates to the field of drug detection, in particular to a visual detection support. BACKGROUND

[0002] At present, after the drug is completed packaging, it needs to be detected visually before it is put on the market. Drug visual detection refers to detecting the size, shape, color, surface and other defects of the drug by mechanical means, and removing the unqualified defective products. After packaging, the packaging needs to be inspected to ensure the airtightness of the drug packaging to ensure that the drug is not contaminated during transportation.

[0003] The packaging equipment usually adopts the way of rotating disc to realize the transportation of the medicine bottle. When detecting the drug packaging, the appearance is usually detected by visual detection. Many devices choose to install the visual detection device directly on the table surface of the packaging equipment to reduce the required space.
