Inspection principle
The scheme is designed according to the actual workpiece conditions
on site, and the liquid level of the bottle is visually detected at
the front end of the labeling machine to replace manual inspection
work. The detection system integrates visual optical hardware and
detection system software as a whole.
The detection equipment is installed on the side of the production
line, and the detection speed is matched to the speed of the
labeling machine under the condition of no obstruction. The
equipment can run all day to improve production efficiency.
System functions&details
Real-time collection of product images through industrial cameras,
and non-contact detection of liquid levels. Obtain the data of the
bottom of the bottle and the liquid level through the linear
measuring device, and calculate the distance. Then, the outline of
the liquid area is retrieved through image data preprocessing, and
the two are matched with each other and combined with thresholding,
morphology and other operations to obtain the height of the liquid
level, realizing real-time detection of the liquid level without
the aid of external measuring instruments.
Inspection Standards
- The incoming material of the product should be stable, and the
liquid level should not shake, which will affect the detection;
- There are bubbles in the internal liquid level of the product,
which will affect the detection;
- There should be no obstructions on the outer bottle body of the
product, which will affect the light source and photography, and
will affect the detection;
- In the actual detection, due to the influence of the critical
fluctuation state of some detection item data, it will lead to a
certain probability of false detection of the product, which can be
adjusted through the parameter setting of the system software to
achieve the actual effect;
- It cannot be effectively detected if the image acquisition is less
than the range of this blind spot.
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.
