Pull Ring Bottle Cap Closures Visual Inspection Machine With Vision Image Processing

Pull Ring Bottle Cap Closures Quality Inspection Machine With Vision Image Processing

nspection principle

The visual inspection machine developed based on machine vision image processing technology has the characteristics of high precision, high speed and multi-sample. The main modules of the system are: trigger positioning module, image processing module and control module. According to user requirements, when the sample moves to the detection position, the camera and the vision system are triggered to output detection signals to complete the detection function.

Trigger module: The equipment is automatic feeding. After the sample arrives at the position, the upper computer equipment provides a triggering signal (to ensure that the consistency deviation of the incoming material position is not greater than 1mm). After the visual system software analysis, if the product is OK, the software interface displays OK , Such as NG products, the software interface displays NG, and outputs the corresponding test pass/fail signal. The central disc of the equipment adopts the photoelectric detection of the diversion device
The positioning is more precise.

Main functions of visual inspection

• High-speed online detection: 450 pcs/min per minute, 600 pcs/min for outer cover.
• Automatically complete the synchronization between the product under inspection and the image obtained by the camera, within 50ms.
• Automatic storage of product images, which can be used for historical query. The maximum storage capacity is 1 million for query.
• Automatically detect the lack of parts, lack of materials, mixed materials, foreign bodies, combination defects, injection molding defects, etc.
• Strobe light source design, reduce light pollution and save energy consumption.
• Automatic statistics (good, bad, total, etc.).
• The system has the function of automatically triggering SMS when the alarm is triggered.
• Detection accuracy: more than 0.2mm2 defects, mainly for lack of materials, foreign bodies, defects, etc.
• Self-learning and testing of product types with different specifications can be performed as required.
• Display of unqualified products, output corresponding defect signals, and proceed to the next step according to requirements.

Our advantages

Feeding system

The feeding mechanism is docked with the discharge port of the upper mechanism, and the upper mechanism transports the sealing cap to the vibrating plate of the feeding system, and the vibrating plate transports the sealing cap to be inspected to the feeding track according to the preset logic.

Inspection platform

When the inspection platform transports the sealing cover to the inspection position, the optical fiber sensor will trigger the camera to take pictures, and the visual inspection system is set according to the inspection index, and the judgment result is given after analysis and operation. When the visual inspection and inspection platform transports the sealing cover to the inspection position, the optical fiber sensor will trigger the camera to take pictures.

Sorting system

According to the judgment result of visual inspection and the preset logic switch, the industrial control PLC notifies the solenoid valve to carry out sorting. The sorting action is realized by the blowing nozzle, and the rejected unqualified materials will be respectively stored in the recycling box.

Vision module (camera, lens, light source)

The visual inspection system mainly includes: camera, lens, light source and image processing software. After the light source illuminates the sample that reaches the inspection position, the imaging system composed of the camera and the lens captures it. When the camera receives the trigger signal, the imaging system will detect the sample. Take pictures and send the image to the image processing system for identification, judge whether the sample is qualified or not, and output the corresponding OK/NG signal for subsequent equipment processing.
