Abstract

The invention discloses a high-speed online cross-shaped detecting and deviation correcting device and a detecting and deviation correcting method using the same. The high-speed online cross-shaped detecting and deviation correcting device comprises a plurality of circular knife machine tables, the ends of four mounting shafts are mounted on the side surfaces of racks of every two adjacent circular knife machine tables, the four corners of a base plate are each provided with a mounting shaft in a shaft sleeve manner, the upper end of the side surface of the base plate is connected with a CCD detecting portion through a slide rail and slider, and the lower end is provided with a detecting table and a backlight through a slide rail and slider; the center of the detecting table is provided with a glass support plate, and a material strip is output through a winding and unwinding roller and is moved on the detecting platform in a fixed-distance manner; and a high-speed camera takes pictures to collect data and transmits the data to an industrial personal computer, and the industrial personal computer analyzes data deviations to control the adjustment positions of the circular knife machine tables. The high-speed online cross-shaped detecting and deviation correcting device and the detecting and deviation correcting method have the advantages that automatic detecting and deviation correcting are carried out, the detection precision is high, human factor errors are avoided, the production efficiency is high, the die-cut yield is high, and safety is high.

Description

technical field [0001] The invention relates to the field of round knife die-cutting detection, in particular to a high-speed online cross detection and deviation correction device and a detection and deviation correction method using the same. Background technique [0002] In the production of 3C products, die-cutting processing is often involved. The traditional production mode is single-piece stamping and die-cutting up and down. The production efficiency of this mode is difficult to form continuous production, and the yield rate is low. In order to improve production, the mode of unloading and unloading the roll-shaped material belt is often used, and the main material is attached to the material belt. There are auxiliary feeding and unwinding rollers to convey the material belt, and the mode of die-cutting with a circular knife machine. This mode has high production efficiency, but There is a problem of poor coincidence accuracy where the main material is attached to th...

Problems solved by technology

[0002] In the production of 3C products, die-cutting processing is often involved. The traditional production mode is a single piece of upper and lower stamping die-cutting. This mode has high production efficiency, it is difficult to form continuous production, and the yield rate is low.

In order to improve production, the mode of unloading and unloading the roll-shaped material belt is often used, and the main material is attached to the material belt. There are auxiliary feeding and unwinding rollers to convey the material belt, and the mode of die-cutting with a circular knife machine. This mode has high production efficiency, but There is a problem of poor coincidence accuracy where the main material is attached to the material belt. Currently, workers often use the naked eye to observe the degree of cross coincidence. According to the observation results, some workers manually adjust the position of the circular knife based on experience. The disadvantages are: First, Manual inspection, workers make subjective judgments through experience, the standards are different, the accuracy of naked eye observation is low, and subsequent adjustments are difficult to match the real results, resulting in poor die-cutting; second, high-frequency shutdowns to manually adjust the position of the circular knife, the speed is slow, resulting in comprehensive equipment comprehensive The efficiency is low, which affects the production capacity; thirdly, due to the poor stability of the equipment, the operators need to observe the overlap degree of the cross at a high frequency and at close range and adjust the position of the circular knife, which indirectly leads to high fatigue intensity of the operators, which in turn leads to low product yield; other Fourth, high-frequency manual operation to adjust equipment will greatly increase the probability of wind direction caused by safety accidents
