Description

Technical Field

[0001] The present invention relates to the technical field of feeder state detection for special-shaped component insertion machines, and specifically to a feeder state detection device for special-shaped component insertion machines. Background Art

[0002] A special-shaped component insertion machine is an automated device dedicated to processing electronic components with various shapes and sizes, and is widely used in the electronics manufacturing industry. Its main features include high precision and flexibility, modular design, high speed and stability, and versatility. During use, the device realizes automatic identification, grasping, and precise insertion of components through a vision recognition system, a precision robotic arm, and a control system, significantly improving production efficiency and product quality. As an important auxiliary device of the special-shaped component insertion machine, the stability and feeding accuracy of the feeder directly affect the performance of the special-shaped component insertion machine.

[0003] To overcome the above defects, the prior art (a Chinese patent application with the application number CN202110874364.2 and the filing date of July 30, 2021) provides a feeder state detection method and device. When it is detected that the remaining quantity satisfies the first condition, continuously monitor the remaining quantity of the chip component and output a first prompt signal; when it is detected that the remaining quantity of the chip component satisfies the second condition, continuously monitor the remaining quantity of the chip component and output a second prompt signal; when it is detected that the remaining quantity of the chip component satisfies the third condition, output a third prompt signal. By detecting the remaining quantity of the chip component in the feeder multiple times and outputting different prompt signals according to different conditions satisfied by the remaining quantity, it realizes automatic monitoring of the remaining quantity state of the chip component in the feeder and automatically reminds the user to replenish the chip component in the feeder. Although the prior art can complete quantitative feeding, during the working process, the traditional feeder state detection mainly relies on technologies such as sensors to detect the feeding state. This method has great limitations. If abnormal situations such as material jams occur between sensors, the sensors are unable to detect them. In other places on the feeding track, problems such as incorrect placement postures of components and abnormal distances caused by component deformation may also occur. The existing sensors cannot detect these abnormalities and cannot issue abnormal warnings to the operator in advance. These abnormalities will cause the insertion head to temporarily interrupt work, which greatly reduces production efficiency.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original feeder state detection device for special-shaped component insertion machines. Summary of the Invention
