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.

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
