1. Inspection Object
As a multi-functional cover, butterfly cover is widely used in
cosmetics, daily chemicals, condiments and other industries. As a
new multi-functional product, butterfly cover is loved by many
consumers and appears in all aspects of home life, so it is
multi-functional. The quality problem of butterfly covers is also
concerned by most manufacturers. Keyi Technology's multi-functional
butterfly cover appearance inspection equipment can effectively
solve the quality defects of products in production for major
manufacturers, and remind them in time.
2. Inspection Principle
By docking the front-end automation mechanism (the connection
method needs to be docked in advance), the multifunctional
butterfly cover product is stably and orderly transferred to a
specific inspection station with the cover facing down, and then
the captured high-pixel sample image is captured by an industrial
camera. It is transmitted to the image processing software. After
the system analysis, it determines the good and bad products, and
controls the corresponding pneumatic components to remove the bad
products. Finally, the qualified products are output.
The software will open the sample comparison standard, and the
production personnel at the customer site can control the
comparison accuracy and select the most suitable accuracy standard
for their own production conditions, thereby controlling the defect
rate.
3. Inspection Details
Our company's design scheme adopts 11 sets of high-pixel industrial
cameras and high-performance stroboscopic light sources, and
conducts a full range of visual inspections for the appearance
defects of multi-functional butterfly cover products. The
inspection speed is 200 pieces/min, and the equipment can achieve
7*24 It operates around the clock every hour, and the unqualified
products can be automatically rejected online.
The whole set of testing equipment includes mechanical parts,
visual electronic hardware and testing system software. The
entrance and exit of the testing machine can be integrated with the
automation mechanism (see the design drawings for the specific
connection method), and can be connected with upstream and
downstream production according to the specific production needs of
customers on site equipment.
| System Parameters |
Dimension | Reference The Drawing | Voltage | 220V 20A 50Hz |
Power | 5.0-6.0kw | Air | Clean Air Without Oil |
Temperature | -20℃ ~ 60℃ | Humidity | Less Than 50% |
2, Black spots, stains, hair, foreign objects, impurities
(different colors), and macula will be analyzed and processed
according to the black spot detection index. If the sample has
transparent oil stains or light-colored black spots, and the gray
value contrast difference is low (below 40), the detection effect
cannot be achieved.
In the actual inspection, due to the influence of the critical
fluctuation state of the data of some inspection items, there will
be a certain probability of false inspection of the product, which
can be adjusted through the parameter setting of the system
software to achieve the actual effect.
3, About the system
(1)Mechanical part:
The mechanical part is the core component of the system, carrying
all the transmission devices and electronic hardware (industrial
cameras, light sources, industrial computers, touch screens,
electrical boxes, etc.).
The glass turntable mechanism in the equipment can open the imaging
angle of the concave surface of the product, so that the industrial
camera can effectively collect images for analysis and processing.
(2)Hardware part
The hardware part includes camera, lens, light source, high-speed
air valve, computer, touch screen and other electrical devices. For
details, please refer to the equipment configuration details.
The overall logic control of the system is realized by a high-speed
FPGA chip, and the specific functions include:
Ø Trigger the camera to take pictures
Ø Trigger light source strobe
Ø Trigger pneumatic parts to reject waste
Ø Control movement speed
Ø Emergency handling in case of similar system jam
Ø Trigger the alarm light signal
