[0029] The metal proximity switch 23 and the bare rod metal proximity switch 31 are electrically connected to the touch screen 19; after the inspection is completed, if the product 99 is missing or welded, the device will alarm and display the position of the missing or welded product in the form of a product image on the touch screen 19 and describe it in text, and at the same time, the system will record the inspection log and record the bad alarm content of each bad inspection in detail. If the product 99 is qualified in the inspection, it will be displayed as qualified and the operator will be prompted to manually unload the material.

[0030] ‌‌In the embodiment of the present application, the metal proximity switch 23 adopts two sizes of proximity switches, M4 and M8. It is a sensor used to detect the proximity of metal objects. It can detect the presence or absence of metal objects without physical contact. This type of proximity switch usually consists of two wires: a power line and a signal line, which simplifies the installation process. When working, the metal proximity switch 23 senses the target object by generating a high-frequency oscillating magnetic field. When a conductive metal object approaches, it will change the magnetic field, thereby triggering the switch action. ‌

[0031] In addition, in the embodiment of the present application, the bare metal proximity switch 31 is a photoelectric proximity switch, which uses the reflection of the light beam by the detected object, and connects the circuit by the synchronization circuit, so as to detect the presence or absence of the object; the object is not limited to metal, and all objects that can reflect light can be detected. The bare metal proximity switch 31 converts the input current into a light signal on the transmitter, and the receiver detects the target object according to the intensity or presence of the received light; the bare metal proximity switch 31 is a kind of sensor, which converts the intensity change of light between the transmitting end and the receiving end into the change of current to achieve the purpose of detection.
