In-Sight Vision System Application Thermal Protector Bimetal Distance Measurement

 A company in Guangzhou is a company specializing in the automatic production and testing of complete sets of equipment for thermostats and protectors. They use the Cognex In-Sight vision system as part of their testing machines. It is mainly used to detect overheating conditions of thermal protectors on electrical appliances. The In-Sight Micro proved to be the best solution when considering the distance of the bimetal inside the circuit breaker.

Since detecting the thermal protector circuit break requires heating to nearly 300 degrees, and the circuit break distance is only about 1 mm, manual inspection is an unachievable task. 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. The In-Sight Micro with 30*30*60mm completed the task well.
The picture shows a clamp with bimetallic sheets 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 bimetallic sheet, and finally use the measuring tool to measure the two lines. direct distance.
During the operation of the equipment, sometimes the furnace temperature is not enough and the bimetallic sheet cannot be opened normally. Through the excellent image feature comparison of the Cognex In-Sight visual system, the open and closed states can be distinguished very well, providing customers with Product testing plays a very good role.
The customer requires this system to complete the size inspection of 10 thermal protectors within 4 seconds after receiving the detection signal, and requires an inspection accuracy of ±0.04mm. However, the Cognex smart camera In-Sight only takes 10ms to detect two. time, creating conditions for customers to increase production.
The customer did not have any vision experience before, but after understanding the Cognex smart camera, the customer found that the Cognex vision system is so simple, and he can master 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 Cognex smart cameras are so easy to use. It saved me development time on this project, allowing me to deliver it to the final customer on time and well."
