Description

Technical Field

[0001] The invention relates to the technical field of blister detection, in particular to a full-automatic blister light inspection machine and a control system. Background Art

[0002] In the prior art, the manufactured drug blisters inevitably have defects such as gaps, cracks, flower heads, etc. These defective blisters must be screened out and removed. At present, the waste blisters are basically removed by manual screening. When sorting defective products with the prior art, the blisters are first poured into a feed funnel, and then scattered on a frosted glass with backlight. The inspectors use human eyes to manually select defective blisters under the backlight light source. This method has the following defects: First, manual inspection uses human eyes to observe the blisters through strong light to determine whether there are defects, because human eyes will become tired due to physiological reasons, resulting in unstable detection and low accuracy; second, due to the large output of blisters, the intensity of manual inspection is high. In order to meet the requirements of mass production, it is often necessary to increase the number of people to meet the requirements of increasing the detection speed, so the cost is relatively high; third, manual work often inevitably causes pollution problems, so products with high requirements for environmental and material hygiene cannot meet the needs of manual inspection. Therefore, manual inspection of blister defects has the problems of low inspection efficiency, low inspection accuracy, high labor cost, high labor intensity and product contamination. Some auxiliary inspection equipment uses machine vision instead of human eyes, but most of them can only inspect one side of the blister and cannot meet production needs. If a blister flipping mechanism is added, the equipment structure will become complicated, which will increase the equipment cost. Summary of the invention
