[0037] The following is a further detailed description of this application.

[0038] Reference Figure 1 and Figure 2 A flat photoelectric sensor disclosed in an embodiment of the present application includes: an outer shell 10, a pull-out plate 20, a sensor component 30 and a control board 40.

[0039] Among them, one end of the outer shell 10 is set to a light-transmitting material, so that when the sensor component 30 is located in the outer shell 10, it will not affect the sensor component 30 to emit and receive light based on the light-transmitting material, that is, it will not affect the detection effect of the sensor component 30, and at the same time it can play a role of isolation and protection.

[0040] The pull-out plate 20 is accommodated in the outer shell 10, and two accommodating grooves 21 are provided at one end close to the light-transmitting material for accommodating the sensor assembly 30. The sensor assembly 30 includes a light receiving element 31 and a light emitting element 32, which are respectively accommodated in the two accommodating grooves 21. The control board 40 is located in the outer shell 10 and is arranged on the pull-out plate 20, and is electrically connected to the light receiving element 31 and the light emitting element 32 to control the light receiving element 31 and the light emitting element 32 to work.

[0041] It is worth mentioning that the two receiving grooves 21 are arranged at an angle, and the light receiving element 31 and the light emitting element 32 are arranged at an angle in the two receiving grooves 21, so that the emitted and reflected light presents an angle form, so as to limit the detection distance of the sensor to a certain range, so as to meet the scene with requirements for the detection distance. In this explanation, both the light emitting element 32 and the light receiving element 31 are set as infrared lamps, which are set toward the light-transmitting material.

[0042] For details, see Figure 3 The end of the outer shell 10 away from the light-transmitting material is set as an opening 11. During assembly, one end of the pull-out plate 20 is pulled out and accommodated in the outer shell 10 through the opening 11, which not only facilitates the installation of the pull-out plate 20, but also facilitates subsequent maintenance and replacement.

[0043] See also Figure 4 A buckle groove 12 is also provided on the side of the outer shell 10, and a snap-fit ​​piece 22 is provided on the pull-out plate 20 corresponding to the buckle groove 12. The outer shell 10 and the pull-out plate 20 are buckled together through the buckle groove 12 and the snap-fit ​​piece 22, which can enhance the connection stability between the two, so as to effectively prevent the pull-out plate 20 from shifting during use, thereby enhancing the reliability and stability of the sensor.

[0044] Among them, fixing holes 13 for fixing are also provided on both sides of the outer shell 10, which can firmly mount the sensor on a workbench or equipment, improve the working stability of the sensor, avoid displacement or damage caused by external force, and make the installation of the sensor more convenient and reliable.

[0045] See also Figure 2 and Figure 3 An indicator sign 14 and a light-transmitting member 15 are provided on the side of the outer shell 10. The indicator sign 14 is attached corresponding to the light direction of the light receiving member 31 and the light emitting member 32. An indicator light 42 is electrically connected to the control board 40. The light-transmitting member 15 is arranged relative to the indicator light 42 to indicate the status of the indicator light 42.

[0046] The indicator 14 is affixed corresponding to the light direction of the light receiving element 31 and the light emitting element 32, and can clearly indicate the light direction of the sensor in the form of an arrow as shown in the figure, so that the user can adjust the installation position and angle of the sensor according to actual needs. The indicator light 42 is electrically connected to the control board 40, which can reflect the working status of the sensor in real time. For example, the indicator light 42 lights up during normal operation and flashes or goes out in abnormal situations, so that the user can find and deal with possible problems with the sensor in a timely manner.

[0047] See also Figure 2The pull-out plate 20 is in the form of a drawer, and limiting columns 24 for engaging the control board 40 are arranged on the inner sides of one end. The control board 40 is provided with grooves 41 corresponding to the limiting columns 24. Through the corresponding arrangement of the limiting columns 24 and the grooves 41, it can be ensured that the control board 40 is stably engaged on the pull-out plate 20 to prevent the control board 40 from shifting during the use of the sensor, thereby enhancing the structural stability of the sensor.

[0048] See also Figure 2 and Figure 3 The photoelectric sensor further includes a fixing member 50 for covering the sensor assembly 30 , and buckle feet 51 are provided on both sides of the fixing member 50 , and buckle grooves 23 are provided on the pull-out plate 20 corresponding to the buckle feet 51 .

[0049] Among them, the inner side of the fixing member 50 is designed to be relative to the shape of the sensor component 30 so as to be wrapped around the sensor component 30. Combined with the design of the snap foot 51 and the snap groove 23, the fixing member 50 can be tightly snapped with the pull-out plate 20. At the same time, the fixing member 50 covers the sensor component 30, which can provide an extra layer of protection for the sensor component 30.

[0050] Specifically, two snap feet 51 are provided on each side of the fixing member 50, and two snap grooves 23 are provided on each side of the pull-out plate 20 corresponding to the snap feet 51, which can significantly enhance the connection stability between the fixing member 50 and the pull-out plate 20, so that the sensor can still maintain internal stability and reliability when facing various external environmental changes.

[0051] See also Figure 3 and Figure 4 The photoelectric sensor also includes a connector 60 located at an end away from the sensor assembly 30 , and one end of the connector 60 passes through the pull-out plate 20 and the control board 40 in sequence, and is electrically connected to the control board 40 .

[0052] The other end of the connector 60 is used to be electrically connected to an external power source or signal line to achieve the connection between the sensor and the external power source or signal line. One end of the connector 60 is bent to pass through the drawer plate 20 and the control board 40 in sequence at the bent portion, thereby ensuring the stability of the connection between the connector 60 and the drawer plate 20 and the control board 40.

[0053] In addition, a through hole 61 for connecting to an external power source is provided at one end of the connector 60 away from the control board 40 , so that an external power source or a signal line can be electrically connected to the sensor via the through hole 61 .

[0054] In summary, the flat photoelectric sensor disclosed in the embodiment of the present application sets the light receiving element 31 and the light emitting element 32 in an angled manner, so that the emitted and reflected light rays are in an angled form. In this way, the detection distance of the sensor can be limited within a certain range to meet the scene with requirements for the detection distance; the end of the outer shell 10 away from the light-transmitting material is designed as an opening 11, which allows one end of the pull-out plate 20 to be accommodated in the outer shell 10 through this opening 11, so that the installation of the pull-out plate 20 can be facilitated, and it also provides great convenience for subsequent maintenance and replacement; the corresponding setting of the buckle groove 12 and the buckle 22 not only enhances the connection stability between the pull-out plate 20 and the outer shell 10, but also effectively prevents the displacement of the pull-out plate 20 during use, further improving the reliability and stability of the sensor.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
