Embodiment 1

[0034] Image-based coil web guiding detection system, such as figure 1 Shown: including preset module, image acquisition module, background module, image preprocessing module, control module, stroke display module, comparison module, distance module and deviation correction warning and alarm module.

[0035] The image acquisition module includes an exposure unit and multiple laser units. The exposure unit is used to select the exposure mode. The exposure mode includes automatic exposure and manual exposure. The exposure threshold can be set to improve the clarity of the image. For example, the automatic exposure method is generally used. When the contrast of the image is small or the image acquisition target is a coil with serious interference, manual exposure is selected, and the image acquisition module resets through the preset Press the button to restore the default option for the exposure mode (the default option can be manual exposure mode).

[0036] The laser unit is u...

Embodiment 2

[0048] The difference with Embodiment 1 is that, if Figure 4 As shown, it also includes a material module and a substrate module. The material module is used to send the material information of the coil to the control module. The material information includes transparent materials and occlusion materials. The material module obtains material information through image information, because when the coil is transparent Infrared rays cannot be used for deviation correction, so the material can not be blocked when infrared rays are detected, and the control module controls the substrate module to substrate the image information of the coiled material according to the material information.

[0049] Such as Figure 5 As shown, the substrate module includes an anti-color bottom plate and a power mechanism. The power mechanism can use an existing servo motor. The control module controls the 180° of each rotation of the servo motor to turn over the anti-color bottom plate. The control ...

Abstract

The present invention relates to the technical field of coil correction technology, in particular to an image-based coil correction detection system, including a preset module, an image acquisition module, a control module, a stroke display module and a comparison module. The preset module is used to limit the deviation of the coil. The image acquisition module is used to obtain the image information of the coil, the control module obtains the image information and sends it to the stroke display module, and the stroke display module traces the edge of the coil image in the image information, and the control module acquires The image information after tracing the edge is sent to the comparison module. The comparison module compares the image information with the preset marking line. The comparison module feeds back the coincidence signal to the control module when the tracing edge coincides with the preset marking line. When the preset marking is turned on, the offset signal for coil deviation correction is fed back to the control module. The present invention feeds back the offset signal when the coil material deviates from the preset marking line, acquires the coil material deviation situation in time, and improves the timeliness of coil material deviation correction.

Description

technical field [0001] The invention relates to the technical field of coil deviation correction, in particular to an image-based coil deviation detection system. Background technique [0002] Coil refers to long-dimension continuous materials such as paper, film, metal foil, rubber, non-woven fabrics, etc., and also includes wire. No matter in the unwinding, intermediate section or winding process of coil processing, the advancing coil will more or less produce axial displacement (deviation), which will eventually cause downtime, uneven winding, and waste products Wait for the consequences. [0003] Coil deflection correction methods include ultrasonic correction and infrared deflection correction. Ultrasonic deflection correction and infrared deflection correction can only be used to detect the edge information of the material. Due to its limitations, EPC deflection correction can only be used. This deflection correction method cannot capture the characteristic informatio...
