[embodiment]
In order to set forth the technical solution of the utility model in further detail, be elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1, shown in Figure 2, the utility model discloses a kind of safe light curtain protective gear, comprise infrared transmission module 1 and the induction of signal module 2 corresponding with infrared transmission module 1; Described infrared transmission module 1 comprises many groups infrared transmitter 11 of array, the parallel light beam conversion lens 13 that are installed in the transmitter channel 12 in every group of infrared transmitter 11 the place aheads and are fixed on transmitter channel 12 outlet ports, the entry end of described transmitter channel 13 is provided with a light inlet 14, and described infrared transmitter 11 is over against light inlet 14; The light beam reinforcement lens 23 that described induction of signal module 2 comprises infrared inductor 21, is installed in the receive path 22 in infrared inductor 21 the place aheads and is fixed on receive path 22 ingress, the outlet end of described receive path 22 is provided with a light output port 24, and described infrared inductor 21 is over against light output port 24; Infrared transmitter 11 in the described infrared transmission module 1 is corresponding one by one with infrared inductor 21 in the induction of signal module 2.Parallel light beam in this real model utility transforms lens 13 can select convex lens for use with light beam reinforcement lens 23.
Receive path 22 described in the utility model is stair-stepping spiral channel, to strengthen the sensitivity that signal receives by the camera principle, improves the Security of equipment.Simultaneously the utility model also to electromagnetic signal, strobelight, welding arc light and around light source etc. have good antijamming capability.
Groundwork process of the present utility model: with reference to shown in Figure 3, after infrared transmission module 1 energising activates, infrared transmitter 11 sends infrared rays, infrared rays passes transmitter channel 13 by light inlet 14, the big I of light inlet 14 is regulated according to actual needs, and this part infrared rays becomes the parallel light beam ejaculation after transforming lens 13 through parallel light beam then; Then light is converged and pass receive path 22 through light beam reinforcement lens 23, and be radiated on the infrared inductor 21 behind the process light output port 24, the IR that many group infrared transmitters 11 send has constituted safe light curtain district 3 between infrared transmission module 1 and induction of signal module 2, the ray density in safe light curtain district 3 can be regulated according to the Environmental Conditions of reality; When object or people's health enters safe light curtain district 3 and during the shield portions infrared rays; part infrared inductor 21 does not send self-locking or signal out of service owing to receive infrared signal to machinery equipment; interrupt machine operation, thus protection operator's the personal safety and the safe handling of machinery equipment.
The utility model safe light curtain protective gear produces protection light curtain by the emission infrared rays, and when the light curtain was blocked, device sent shielding signals, and the machinery that control has potential risk quits work, and avoids taking place security incident.
