Vision Inspection Systems For Empty Plastic Bottles And Containers

Inspection standards

**For defect features such as black spots and bubbles, the gray value contrast difference corresponding to the detection index must be greater than 30 (it can be understood as: put the sample at an arm’s length, about 30cm or more, and the defect features can be seen visually), which can be effectively detection. If the sample has transparent oil stains or light-colored black spots, and the gray value contrast difference is low (less than 30), the detection effect cannot be achieved. Due to the different complexity of the structural features of different products, in actual application, there will be a certain detection blind spot in the structural overlapping area of the plane lens imaging, and the image acquisition cannot reach the range of this blind spot, so it cannot effective detection.

Inspection principle

The PET bottle inspection equipment is equipped with a total of 10 sets of high-resolution industrial cameras to conduct a comprehensive inspection of the geometric dimensions and appearance defects of key points such as the bottle mouth, bottle bottom, and bottle body of PET bottles.The inspection speed is 300 pieces/minute, and the equipment can operate 7*24 hours a day. Unqualified products can be automatically removed online.

Mechanical part

• The transmission part is the core component of the system, carrying all the transmission devices and electronic hardware.
• Electronic hardware part
• The electronic hardware part includes industrial cameras, industrial lenses, light sources, triggers, solenoid valves (rejecting waste),
• System electrical control box (responsible for electrical and logic control), three-color alarm lights, and 21-inch touch screen.
• The overall logic control of the system is realized by a high-speed FPGA chip, and its specific functions include:
• Trigger the camera to take pictures
• Trigger light source strobe
• Trigger the solenoid valve cylinder to remove waste products flexibly
• Trigger the alarm light signal
• Software part

The software is the general control platform of the equipment, and its specific functions are as follows:

• Enable and disable the system detection function.
• Adjustment of detection index parameters and accuracy.
• Template sampling and storage, sample detection information storage and recall.
• Camera screen calibration function.
• Real-time production information (pass rate, total output, speed, etc.) display of the system, historical production information browsing
• Browse, export and save functions.
• Permission management according to the login account (for example, general operation users disable parameter adjustment permissions).
• The operation and adjustment of the mechanical parts of the system (such as: opening of the transmission device, adjustment of the air injection time of the air valve,
• alarm signal adjustment).
• Additional functions that Party A needs to add.

After-sale service

The company has a complete technical service team and rapid response mechanism, and has dedicated service specialists for each customer, who can receive technical consultation and fault reports from customers at any time. And to ensure rapid response to customer emergencies, to ensure that customers receive satisfactory service.During the epidemic or due to special reasons, when after-sales engineers are unable to reach the site, the service center can remotely adjust customer equipment for troubleshooting and technical consultation.

After the equipment arrives at the customer site, the after-sales engineer arrives in time to carry out equipment installation, commissioning, and operation training. The product quality of the whole machine is traceable, and the quality warranty period is 1 year from the date of acceptance. In the event of non-human faults during the warranty period, after-sales engineers will quickly arrive at the site or provide remote guidance for free maintenance.
