[0026] Embodiment

[0027] As Figures 1-3As shown in the figure, this embodiment provides a multifunctional optoelectronic sensor, which includes a housing 1. The housing 1 includes a bottom cover 101 and an outer shell 102. The bottom cover 101 and the outer shell 102 are fixedly installed by bolts. A light-transmitting hole 1021 is formed on the side surface of the outer shell 102. A PCBA board 2 is fixedly installed inside the housing 1 by bolts. On the surface of the PCBA board 2 near the light-transmitting hole 1021, a receiving element 21 and a transmitting lamp 22 are integrated. The transmitting lamp 22 is used to emit a light source. After the light source is reflected and returns, it is received by the receiving element 21, and the light signal is converted into an electrical signal to complete the measurement. On the side of the PCBA board 2 away from the light-transmitting hole 1021, a variable resistor 23 and a changeover switch 24 are integrated. On the side of the housing 1 near the variable resistor 23 and the changeover switch 24, a potentiometer knob 31 and a changeover knob 32 are embedded. The potentiometer knob 31 and the changeover knob 32 are respectively connected to the variable resistor 23 and the changeover switch 24 in a cooperative manner. The variable resistor 23 is a knob-type variable resistor 23. By rotating the potentiometer knob 31, the resistance value of the variable resistor 23 can be adjusted, thereby changing the detection distance of the sensor. The changeover knob 32 adjusts the switch state of the changeover switch 24, so that the sensor is in a normally open or normally closed working state.

[0028] In one embodiment, a lens bracket 4 is fixedly installed on the surface of the PCBA board 2 by bolts. The lens bracket 4 covers the receiving element 21 and the transmitting lamp 22. On the side of the lens bracket 4 away from the PCBA board 2, a combined lens 5 is embedded. The combined lens 5 is divided into two upper and lower lenses, corresponding to the receiving element 21 and the transmitting lamp 22 respectively, to improve the irradiation and receiving effects.

[0029] Further, a partition hole 51 is formed in the middle of the combined lens 5. At the position corresponding to the partition hole 51 in the middle of the lens bracket 4, a first partition plate 41 is fixedly connected. The first partition plate 41 is embedded in the partition hole 51. The combined lens 5 is divided into two upper and lower parts by the first partition plate 41, and the light of the upper and lower parts is isolated by the first partition plate 41 to avoid mutual influence of cross-talk light. The first partition plate 41 divides the lens bracket 4 into two upper and lower cavities. The receiving element 21 and the transmitting lamp 22 are respectively embedded in the two cavities. The receiving element 21 and the transmitting lamp 22 are in different cavities, so that the transmitting lamp 22 and the receiving element 21 will not affect each other.

[0030] Further, a second partition plate is fixedly connected to the middle of the light-transmitting hole 1021. The second partition plate divides the light-transmitting hole 1021 into two upper and lower cavities. The two cavities of the light-transmitting hole 1021 are respectively arranged in one-to-one correspondence with the two cavities of the lens bracket 4. The second partition plate further separates the transmitting lamp 22 and the receiving element 21 to avoid cross-talk and mutual influence.

[0031] Further, clamping grooves 42 are formed on both sides of the lens holder 4. At positions corresponding to the clamping grooves 42 on both sides of the combined lens 5, clamping blocks 52 are fixedly connected. The clamping blocks 52 are embedded in the clamping grooves 42. Positioning posts 43 are fixedly connected to both sides of the lens holder 4 respectively. At positions corresponding to the positioning posts 43 on both sides of the combined lens 5, positioning grooves 53 are formed. The positioning posts 43 are embedded in the positioning grooves 53. When installing the combined lens 5, first align the positioning grooves 53 and the positioning posts 43. After the positions are accurate, the clamping blocks 52 are inserted into the clamping grooves 42 to be clamped, thus completing the installation of the combined lens 5. The installation is convenient and fast.

[0032] In one embodiment, the housing 1 includes an outer shell 102 and a bottom cover 101. The outer shell 102 and the bottom cover 101 are fixedly connected by bolts. The light-transmitting hole 1021 is integrally formed and connected to the surface of the outer shell 102. A cable through-hole is provided on the side surface of the bottom cover 101. A connecting cable 8 is embedded in the cable through-hole. The connecting cable 8 is connected to the PCBA board 2. One end of the connecting cable 8 is connected to the PCBA board 2, and the other end is connected to a power supply or a controller to achieve data transmission and power supply.

[0033] Further, a window lens 6 is embedded in the light-transmitting hole 1021. The window lens 6 is a transparent lens, which can prevent dust and the like from entering the sensor interior without affecting the passage of light, thereby affecting the sensor accuracy.

[0034] In one embodiment, an indicator light 25 is soldered on the surface of the PCBA board 2. An indicator light hole 1023 is formed at the end of the outer shell 102. A light guide column 7 is embedded in the indicator light hole 1023. The light of the indicator light 25 is emitted to the outside of the outer shell 102 through the light guide column 7. The working state of the sensor can be directly seen by observing the indicator light 25.

[0035] Further, two mounting and fixing holes 1025 are formed on the side surface of the outer shell 102. The sensor is fixedly installed and used by cooperating with M13 bolts through the two mounting and fixing holes 1025.

[0036] Further, an external thread 1024 is provided on the outside of the light-transmitting hole 1021. The sensor is fixedly installed by cooperating with an M18 nut through the external thread 1024.

[0037] The working principle of the present utility model: According to the usage requirements, after the sensor is installed and fixed by an M13 bolt or an M18 nut, it is switched to the normally open state through the switching knob 32, and then adjusted to a suitable detection distance through the potentiometer knob 31. Then, the emitting lamp 22 emits light. After passing through the combined lens 5 and the light-transmitting hole 1021, the light contacts the measured object and is reflected. The reflected light is received by the receiving element 21 after passing through the light-transmitting hole 1021 and the combined lens 5, thus completing the measurement.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
