Distinguishing the front and back of materials on flexible vibration discs
Distinguishing the front and back of materials on flexible vibration discs
Choose Akusense Vision Sensor VSD10 series, with a detection distance of 30-300mm, compact size and easy installation.Speaking of vibration discs, I believe everyone is familiar with them. It is an auxiliary feeding device for automatic assembly or processing machinery, also known as a vibrating disc automatic feeding machine. It can arrange various small materials in an orderly manner, adjust the posture of products to achieve continuous feeding, and provide correct assembly accessories for automatic assembly equipment to cooperate with automatic processing machinery to complete product processing.
Among them, the arrangement posture of the products is crucial. The flexible vibration disc incorporates visual positioning and robot grasping in automated feeding, compatible with vibration discs for various types of materials, such as complex geometric shapes, parts with scratch resistant surface coatings, thin sheet parts, irregular parts, etc. It easily solves the difficult problems of disorderly, scattered, scratched, and distinguishing front and back sides that traditional vibration discs cannot solve.
In this issue, Xiao Ming will share the application of Akusense Sensing's visual sensor on flexible vibration discs~
▲ Application scenarios
The material vibrates in the vibrating disc. After the vibration stops, a visual sensor needs to be used to take photos. After processing by a visual image processor, the front and back of the material can be identified.
If the material direction is positive, the robotic arm grabs the product; If the material direction is reversed, it is considered NG, and the robotic arm does not grab the product. Wait for the next vibration of the vibrating disc, and repeat this process in a loop~
⭐ Testing difficulties
1. The similarity between the front and back of groove shaped parts is high
2. The detection process is in a state of vibration
3. The installation distance is fixed at 100 meters; 40mm; installation space is small
▲ Solution
1. Observing the imaging characteristics of the front and back of the material, the presence or absence of holes (spots) at specific locations of the material can be used to determine the front and back
2. Select Akusense Vision Sensor VSD10 series, with a detection distance of 30-300mm, small size and easy installation
3. By using template matching for detection, features with small changes can be found, ensuring high-precision, high-efficiency, and highly stable detection.
4. Multiple solutions can be easily created online to support forward and backward detection of materials with different appearance sizes.
5. Support multiple forms of switching schemes, making it convenient to quickly switch and execute detection tasks.
