Recheck platform and quality inspection system of prints

Abstract

The invention discloses a recheck platform which is used for rechecking defects in quality inspection of prints and comprises a rack, a working table, an unwinding wheel, a winding wheel, a position detection device, a power device and a microcontroller, wherein, the unwinding wheel and the winding wheel are arranged on the rack; the unwinding wheel transmits the prints to the winding wheel to rewind the prints; the winding wheel is connected with a power device; the position detection device detects the position to which the prints are transmitted and is connected with the microcontroller; the microcontroller stores the position information of defects of the prints and compares with the information of the position when the prints are transmitted to control the power device. The recheck platform can lighten the burden of visual sense detection device, thus the visual sense detection device is only responsible for detection, reconstructs the detection process, separates the process links such as time consuming stopping rejection and label supplementing and the like from the detection process, lowers cost and improves the efficiency of quality detection. The invention also relates to a system adopting the platform to detect the quality of prints.

Description

technical field [0001] The invention relates to a print quality inspection technology, in particular to a re-inspection platform and a system for printing quality inspection using the platform. Background technique [0002] In recent years, the domestic printing industry has maintained a high-speed growth trend. However, with the expansion of the industry, the competition in the industry has become increasingly fierce. At the same time, the ever-increasing quality requirements from clients have also put forward higher requirements for printing companies. At present, label printing enterprises are faced with the problems of heavy quality inspection workload, shipment capacity cannot accurately match production capacity, increased missed inspections, increased reverse orders, and increased labor costs. [0003] Most large enterprises in the industry have started to use visual inspection equipment for quality control. Visual inspection equipment can effectively improve the qua...

AI Technical Summary

Problems solved by technology

When the scrap rate detected by the equipment is relatively high, it needs to be shut down continuously for manual operation, and the detection efficiency of the equipment will be reduced

Existing visual inspection equipment only focuses on improving the precision, accuracy and speed of observation, judgment, and defect discovery, but does not pay attention to the time-consuming downtime. The longest downtime to eliminate and subsidize good products takes up about 20% of the entire inspection process. 60%-70% of the time, it is impossible to save this part of time without the cooperation of other high-precision automation equipment, which is the root cause of the low efficiency of visual inspection equipment

[0006] 2) Insufficient ability to detect special defects

However, there are common problems in the detection of products with special optical characteristics such as scratches, bubbles, poor shape, size, spacing, etc.
