Guangzhou Bangze is a company specializing in the automatic production and inspection of thermostats and protectors. The Cognex In-Sight vision system is part of their inspection machines, mainly used to detect the overheating of thermal protectors on electrical appliances. When breaking down the distance of the bimetal inside the circuit, the In-Sight Micro proved to be the best solution.
Since the detection of thermal protector open circuit needs to be heated to nearly 300 degrees, and the distance of the open circuit is only about 1 mm, it is an impossible task to use manual detection. We provide customers with the In-Sight 1020 vision system as a solution.
First of all, due to the high temperature in the heating furnace, the camera can only be installed in a small insulated space, and the In-Sight Micro with 30*30*60mm completes the task well.
The picture shows the jig with the bimetal strips on the left and right. First, use the picture positioning tool to locate the distance feature that needs to be measured, then use the edge finding tool to automatically find the edge of the bimetal strip, and finally use the measuring tool to measure the two lines directly. distance.
During the operation of the equipment, sometimes the furnace temperature is not enough to cause the bimetal sheet to be unable to open normally. Through the excellent image feature comparison of Cognex In-Sight vision system, the state of opening and closing can be well distinguished. Product testing plays a very good role.
The customer requires the system to complete the size detection of 10 thermal protectors within 4 seconds after receiving the detection signal, and the detection accuracy is required to be ±0.04mm, while the Cognex smart camera In-Sight only needs 10ms to detect two time, creating conditions for customers to increase production.
The customer did not have any experience in vision before, but the customer found out that the Cognex vision system is so simple through the understanding of Cognex smart cameras, and they have mastered the required information in a short time, and it is very simple and convenient. to communicate with the customer’s software.
Xu Gong, the customer’s chief engineer, said: I didn’t expect that the Cognex smart camera was so easy to use, which saved my development time for this project, allowing me to deliver it to the final customer on time and in a good manner.
