I. Equipment Introduction 1. Equipment Purpose: Online inspection of the cap quality of Yangyuan can production lines and automatic rejection of defective caps.
2. Equipment Features
◆ Non-contact, online inspection, harmless to the product.
◆ High inspection speed, up to 60,000 cans/hour.
◆ Flexible human-machine interface with multi-level user permissions.
◆ Equipped with an industrial-grade cooling system to prevent system crashes caused by extended summer operation.
◆ Customizable functions based on the customer's actual production conditions.
◆ Automatically stores daily photos of defective caps, with customizable storage time.
◆ 24-hour remote service (remote control of the equipment)
◆ Continuous rejection and shutdown (automatically stops the line after a certain number of defective products are rejected)
◆ 360° cap inspection, reducing false rejections caused by can rubbing or grabbing.
◆ Zero-delay cap inspection, minimizing the impact of cap and packaging color on cap inspection.
II. Detection Functions
1).Bottle cap presence
2).Cap angle deviation (deviation >= 5°)
3).Cap pop-up (caused by can expansion or air leakage, deviation >= 1mm)
3. Installation location
On-site installation location conditions: 1.5-2 meters straight behind the sealing machine.
IV. Detection Principle
Cap pop-up detection principle:
Using curved surface scanning technology, the top surface of the can cap is continuously scanned. If the seal is not good or the internal pressure of the bottle is abnormal, the pop-up cap will suddenly change, thus determining whether the cap seal is qualified.
Sample image processing effect, the left is the original image, the right is the processed image
Lid angle detection principle:
A Gigabit digital camera is used to take pictures from top to bottom to collect images of can caps. The images are digitally analyzed and matched with templates 360°. Cans with unqualified cap angles are automatically removed online.
When a can passes by a positioning sensor, it detects its arrival and the control unit records the can's identification number and the current encoder signal. The positioning sensor triggers a digital camera to capture an image of the can's cap and transmits it to the image processor via the network. The image processor processes and analyzes the received image and transmits the results to the human-machine interface for dynamic display and the control unit. Upon receiving the unqualified cap signal, the control unit notifies the rejector to remove the can with the corresponding identification number and unqualified cap online.
V. Equipment Configuration Details and Inspection Accuracy
(I) Detailed Equipment Description
A. Technical Parameters

D. Detection accuracy:
Testing items | Detection content
| Schematic diagram
| Rejection rate
| False detection rate
| |
Bottle cap testing | No cap
| ≥99.99% | <= 0.03% | ||
Cap angle offset
| Bottle cap deviation angle>=5°
| ≥99.9% | <= 0.03% | ||
The lid pops up (caused by bulging can or air leakage)
| Deviation value>=1mm
| ≥99.9% | <= 0.03% | ||
Note: The above detection accuracy is standard accuracy. The specific accuracy needs to be adjusted according to the condition of the product bottle cap and the degree of jitter of the production line. The final right of interpretation belongs to Maotong Company. | |||||
Note: The rejection rate of the test item "no bottle cap" described in the table means that out of 10,000 packages of unqualified products without bottle caps tested by the equipment, there may be 1 can that is not rejected. This is only theoretical experimental data, and the same applies to other test items.
