Description

Technical Field

[0001] This utility model relates to the field of slotted photoelectric sensors, specifically a slotted photoelectric sensor. Background Technology

[0002] The slotted photoelectric sensor is a general-purpose photoelectric sensor mainly used to monitor a series of light signals and their occurrence time to detect and record the operating status of a machine. It is actually a type of through-beam photoelectric switch, also known as a U-shaped photoelectric switch. It is an infrared sensing photoelectric product composed of an infrared emitting tube and an infrared receiving tube. The slot width determines the strength of the sensing signal and the distance at which the signal is received. Using light as a medium, the infrared light between the emitting and receiving objects is received and converted to detect the position of an object. Like other proximity switches, the slotted photoelectric switch is non-contact, less constrained by the detected object, and has a long detection distance, enabling long-distance detection with high accuracy. It can detect small objects and has a very wide range of applications.

[0003] Existing technologies for slotted photoelectric sensors still have certain drawbacks in their use. The installation direction of traditional slotted photoelectric sensors is usually fixed and needs to be customized according to the installation location, which limits the installation range of slotted photoelectric sensors. In addition, the wiring is generally exposed to the outside, and under long-term use, the wiring is prone to loosening, affecting the use of slotted photoelectric sensors. Utility Model Content

[0004] The purpose of this utility model is to provide a slotted photoelectric sensor to solve the problems mentioned in the background art, such as the fact that the installation direction of traditional slotted photoelectric sensors is usually fixed and needs to be customized according to the installation position, which limits the installation range of slotted photoelectric sensors, and the wiring position is generally exposed to the outside. Under long-term use, the wiring position is prone to loosening, which affects the use of slotted photoelectric sensors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slotted photoelectric sensor, comprising a slotted photoelectric sensor housing, a wiring slot at the rear end of the bottom of the slotted photoelectric sensor housing, a wiring piece inside the wiring slot, a cable connected to the wiring piece, a sealing cover below the wiring slot, a wire-locking port in the middle of the sealing cover, a shell cover at the bottom of the slotted photoelectric sensor housing, a slot on the side of the shell cover connected to the wiring slot, an adjustable mounting piece inside the slot, a fixing screw hole at the outer end of the adjustable mounting piece, and an infrared sensing lamp inside the slotted photoelectric sensor housing located at the slot.

[0006] In a further embodiment, the sealing cover is connected to the wiring groove by a rotating pin, and the sealing cover is connected to the groove-shaped photoelectric sensor housing by a snap-fit ​​connection.

[0007] In a further embodiment, the cover is fixedly connected to the slotted photoelectric sensor housing by a snap fastener, and the cover is fixedly connected to the wiring slot by a fixing screw.

[0008] In a further embodiment, the inner end of the adjustable mounting piece is rotatably connected to the slot via a rotating buckle, and each adjustable mounting piece is provided with two fixing screw holes.

[0009] In a further embodiment, the cable and the sealing cap are connected by a snap fastener.

[0010] In a further embodiment, the thickness of the adjustable mounting piece is the same as the depth of the slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features an adjustable mounting plate inside the slot. This structure can be adjusted backward or to the side by rotation, allowing the slotted photoelectric sensor to be installed vertically or horizontally, increasing installation flexibility and meeting more installation needs. A sealing cover is provided at the bottom of the wiring slot, which can centrally seal the cable connection points inside. This serves two purposes: firstly, it better fixes the connection points and prevents the cables from loosening; secondly, it facilitates maintenance and replacement. The wiring slot provides convenient access, making the work simpler and faster. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A wiring groove 6 is provided at the rear end of the bottom of the slotted photoelectric sensor housing 1. A wiring piece 10 is provided inside the wiring groove 6, and a cable 3 is connected to the wiring piece 10. A sealing cover 4 is provided below the wiring groove 6. The cable 3 is connected to the sealing cover 4 by a snap-fit ​​connection. A wire-locking port 11 is provided in the middle of the sealing cover 4. A shell cover 9 is provided at the bottom of the slotted photoelectric sensor housing 1. A slot 8 is provided on the side of the shell cover 9 that connects to the wiring groove 6. An adjustable mounting piece 2 is provided inside the slot 8 for adjustment. The mounting plate 2 has a fixing screw hole 12 at its outer end. The slotted photoelectric sensor housing 1 has an infrared sensor lamp 14 located at the slot opening. The wiring groove 6 is used to hide the connection position of the cable 3. The sealing cover 4 is used to seal the wiring groove 6. The cable clamp 11 is used to fix the installation position of the cable 3. The shell cover 9 is used to seal the bottom of the slotted photoelectric sensor housing 1. The slot opening 8 is used to hide and install the adjustable mounting plate 2. The adjustable mounting plate 2 is used to install the slotted photoelectric sensor housing 1. The infrared sensor lamp 14 is used to sense obstacles.

[0021] The sealing cover 4 is connected to the wiring groove 6 by a rotating pin 5, and the sealing cover 4 is connected to the groove-shaped photoelectric sensor housing 1 by a snap-fit ​​connection. The rotating pin 5 is used to open and close the sealing cover 4 by rotation.

[0022] The cover 9 is fixedly connected to the slotted photoelectric sensor housing 1 by a snap fastener, and the cover 9 is fixedly connected to the wiring slot 6 by a fixing screw 7. The snap fastener connection facilitates the installation or removal of the cover 9 and the slotted photoelectric sensor housing 1, and the fixing screw 7 is used to fix the position of the cover 9.

[0023] The inner end of the adjustable mounting piece 2 is rotatably connected to the groove 8 via a rotating buckle 13, and each adjustable mounting piece 2 is provided with two fixing screw holes 12. The adjustable mounting piece 2 can be adjusted by rotation via the rotating buckle 13. The thickness of the adjustable mounting piece 2 is the same as the depth of the groove 8.

Open the sealing cover 4 and connect and fix the cable 3 to the wiring piece 10 according to the correct wiring diagram. Close the sealing cover 4 to seal and fix the wiring slot 6, so that the cable 3 is securely connected to the wire clamp 11, thereby fixing the position of the cable 3. Start the slotted photoelectric sensor housing 1, and emit a beam of light through the infrared sensor lamp 14. When an obstacle enters the slot, it blocks the infrared sensor lamp 14, and the light signal received by the connector weakens or disappears, thereby generating an electrical signal. This electrical signal can be recognized and processed by the processor or controller, thereby realizing the detection and measurement of the object.
