[0002] The light curtain system is mainly applied to production operations to achieve safe production. At present, the light curtain system generally includes an independently arranged transmitter and a receiver. The transmitter emits infrared light, and the receiver receives the infrared light emitted by the transmitter. When a person or an object passes through this infrared light, the infrared light will be blocked to identify that there is a person or an object in the working area, and the machine in operation will be immediately shut down or an alarm will be issued.

[0003] The utility model with the publication number of CN219831414U discloses a light curtain sensor, which includes a transmitter and a receiver arranged oppositely. The transmitter and the receiver are fixed by a bracket. Translucent plates are provided on the opposite sides of the transmitter and the receiver. The interior of the transmitter includes a transmitting tube and a transmitting lens, and the transmitting lens is located between the translucent plate and the transmitting tube; the interior of the receiver includes a receiving tube and a receiving lens, and the receiving lens is located between the receiving tube and the translucent plate. Both the transmitting lens and the receiving lens are convex lenses. However, the above-mentioned transmitting end and receiving end are two independently arranged components. When multiple groups of light curtain devices need to be installed, the installation is inconvenient and the occupied space is large. Moreover, the axes of the transmitting tube, the transmitting lens, the two translucent plates, and the receiving lens are located on the same straight line, and the positioning operation is complicated. Summary of the Utility Model
