Abstract
An optical signal transmit-receive reflection cover of a photoelectric sensor is provided. The reflection cover comprises a cavity for emitting optical signals and a cavity for receiving optical signals, emitting holes are arranged on the bottom part of the cavity for emitting optical signals, receiving holes are arranged on the bottom part of the cavity for receiving optical signals, and the cavity for emitting optical signals is a cone-shaped structure. The reflection cover is characterized in that a plurality of step structures is adopted in the cavity for receiving optical signals. In the optical signal transmit-receive reflection cover of the photoelectric sensor, as the step structures are adopted in the cavity for receiving optical signals, the step structures are not converged on the receiving holes, the optical signals reaching the steps can be reflected to the receiving holes again after being reflected to a collector lens. Thus, the reflection cover can be used for enhancing receiving sensitivity of the photoelectric sensor of the prior art.
Description
Technical field
The utility model relates to the industrial automation instrument industry, specifically is meant a kind of optical signal transceiver reflex housing of photoelectric sensor.
Background technology
The optical signal transceiver reflex housing of the photoelectric sensor of prior art, it comprises the cavity of launching light signal and the cavity of accepting light signal, the cavity of emission light signal adopts identical cone structure with the cavity of accepting light signal.For the cavity of acknowledge(ment) signal, light signal process collector lens is assembled the back and is arrived receiver hole, and does not converge to receiver hole, and the ratio to receiver hole after the light signal on the arrival conical surface is reflected is lower, influences the sensitivity of accepting of photoelectric sensor.
Summary of the invention
The utility model purpose is to propose a kind of optical signal transceiver reflex housing that photoelectric sensor is accepted the photoelectric sensor of sensitivity that improves.
The technical scheme of the utility model is: the optical signal transceiver reflex housing of the photoelectric sensor of the utility model; It comprises the cavity of launching light signal and the cavity of accepting light signal; The cavity bottom of emission light signal has transmitting aperture; The cavity bottom of accepting light signal has receiver hole, and the cavity of emission light signal adopts cone structure, it is characterized in that the cavity of accepting light signal adopts a plurality of ledge structures.
The optical signal transceiver reflex housing of the photoelectric sensor of the utility model; Adopt a plurality of ledge structures owing to accept the cavity of light signal; Do not converge to receiver hole, can be reflexed to receiver hole by collector lens once more after the light signal on the arrival step is reflected to collector lens.Therefore, the utility model can improve prior art photoelectric sensor accept sensitivity.
Description of drawings
Fig. 1 is the optical signal transceiver reflex housing synoptic diagram of the photoelectric sensor of the utility model.
Fig. 2 is the structural representation of optical signal transceiver reflex housing of the photoelectric sensor of the utility model.
Embodiment
