Description

Technical Field

[0001] This utility model relates to a laser sensor, and more particularly to an active detection laser sensor for use in the field of sensors. Background Technology

[0002] In fields such as industrial automation, logistics warehousing, and intelligent security, laser sensors are widely used as important detection components for object detection, distance measurement, and location positioning. However, existing laser sensors still face many problems in practical applications and struggle to meet the demands of complex and ever-changing working conditions.

[0003] Chinese patent CN205719021U discloses a small-beam through-beam laser sensor, which includes output circuit elements, a first detection head, a second detection head, a first connecting line, a second connecting line, and a third connecting line. The minimum detection object diameter of this utility model is only 0.1mm, and the maximum detection distance is 5m. It has a simple structure, reasonable design, and is easy to use. It is suitable for small objects and long-distance detection. It adopts a metal shell, which is relatively robust and not easily damaged. Not only is the light spot small, which can detect very small objects, but it also has a long detection distance and good stability.

[0004] Existing laser sensors have limitations in adjustment capabilities. Typically, the positions of the transmitter and receiver can only be changed by manually disassembling and reinstalling them, which is cumbersome and inefficient, making it difficult to quickly adapt to the detection needs of products with different specifications. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing laser sensors have limitations in adjustment functions. Usually, the positions of the transmitter and receiver can only be changed by manually disassembling and reinstalling them, which is cumbersome and inefficient, and makes it difficult to quickly adapt to the detection needs of products of different specifications.

[0006] To address the aforementioned problems, this utility model provides an active detection laser sensor, comprising a device body with a vertical pole. A horizontal load-bearing working plate is fixedly connected to the upper end of the vertical pole. Horizontal sliding grooves are symmetrically formed on the left and right sides of the upper end of the horizontal load-bearing working plate. An elastic reset component is fixedly connected to one end of each horizontal sliding groove that is far apart from the other. A U-shaped adjustable stop block is slidably connected to the inner end of each horizontal sliding groove. A retractable self-rebound placement pole is provided at the upper end of the U-shaped adjustable stop block. A laser emitting sensor and a laser receiving sensor are respectively fixedly connected to the upper ends of the two retractable self-rebound placement poles. A motor is fixedly connected to the middle of the upper end of the horizontal load-bearing working plate. An arc-shaped horizontal plate is connected to the output end of the motor. Two smoothly curved, gradually rising top surfaces are fixedly connected to the upper end of the arc-shaped horizontal plate.

[0007] In the aforementioned active detection laser sensor, this solution further expands the adjustment range by linking vertical and horizontal adjustments when the positions of the laser emitting sensor and the laser receiving sensor need to be adjusted under different working conditions. This bidirectional adjustment mechanism enables the sensor to adapt to complex and ever-changing spatial detection scenarios.

[0008] As a further improvement of this application, the two smooth, gradually rising curved top surfaces are symmetrically arranged, and the elastic reset member and the U-shaped adjustable stop block are interconnected.

[0009] As a further improvement to this application, the smooth, curved, gradually rising top surface is adapted to the side opening of the U-shaped adjustable stop block, and the outer end of the arc-shaped horizontal piece is provided with a sandwich groove.

[0010] As a further improvement of this application, the inner end of the interlayer slot is provided with multiple roller rotating parts, which are arranged circumferentially at equal intervals.

[0011] As a further improvement to this application, the inner walls of the two U-shaped adjustable blocks that are far apart from each other are fixedly connected with guide rail grooves, and the guide rail grooves are slidably connected to the roller rotating parts.

[0012] As a further improvement to this application, a sturdy base is fixedly connected to the lower end of the vertical pole, and threaded nails are symmetrically arranged on the front and rear sides of the upper end of the sturdy base.

[0013] In summary, this solution expands the adjustment range by enabling vertical and horizontal linkage adjustment when the positions of the laser emitting and receiving sensors need to be adjusted under different working conditions. This bidirectional adjustment mechanism allows the sensors to adapt to complex and varied spatial detection scenarios, such as cargo detection in automated warehouses and irregular object contour detection. It can adjust the sensor position in all directions to meet the detection requirements of different angles, heights, and distances, effectively improving the applicability and detection accuracy of the sensors. Furthermore, the roller rotating component in the slotted interlayer of the outer end of the arc-shaped horizontal plate slides in conjunction with the guide rail groove on the inner side wall of the U-shaped adjustable abutment block, ensuring the stability and smoothness of the arc-shaped horizontal plate's rotation.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-6 This invention illustrates an active laser sensor comprising a device body 1, a vertical pole 2, a horizontal load-bearing working plate 17 fixedly connected to the upper end of the vertical pole 2, horizontal sliding grooves 3 symmetrically formed on the left and right sides of the upper end of the horizontal load-bearing working plate 17, elastic reset members 4 fixedly connected to the ends of the two horizontal sliding grooves 3 that are far apart from each other, a U-shaped adjustable stop block 5 slidably connected to the inner end of the horizontal sliding groove 3, a retractable self-rebound placement pole 6 provided at the upper end of the U-shaped adjustable stop block 5, a laser emitting sensor 7 and a laser receiving sensor 8 fixedly connected to the upper ends of the two retractable self-rebound placement poles 6 respectively, a motor 9 fixedly connected to the middle of the upper end of the horizontal load-bearing working plate 17, an arc-shaped horizontal plate 10 connected to the output end of the motor 9, and two smoothly curved gradually rising top surfaces 13 fixedly connected to the upper end of the arc-shaped horizontal plate 10.

[0026] Figures 1-6The two smoothly curved, gradually rising top surfaces 13 are symmetrically arranged. The elastic reset member 4 and the U-shaped adjustable stop block 5 are connected to each other. The side openings of the smoothly curved, gradually rising top surfaces 13 and the U-shaped adjustable stop block 5 are adapted to each other. The outer end of the arc-shaped horizontal piece 10 is provided with a sandwich groove 16. The inner end of the sandwich groove 16 is provided with multiple roller rotating members 11. The multiple roller rotating members 11 are arranged circumferentially at equal intervals. The inner sidewalls of the two U-shaped adjustable stop blocks 5 that are far apart from each other are fixedly connected with guide rail grooves 12. The guide rail grooves 12 are slidably connected to the roller rotating members 11.

[0027] Figures 2-6 When this solution is in operation, the vertical pole 2 is first installed on a suitable base surface using the threaded pins 15 on the stable base 14. When it is necessary to adjust the distance between the laser emitting sensor 7 and the laser receiving sensor 8 to adapt to different working conditions, the U-shaped adjustable stop 5 can slide in the transverse slide groove 3. Since the elastic reset component 4 is connected to the U-shaped adjustable stop 5, the motor 9 is started. The motor 9 drives the arc-shaped horizontal plate 10 to rotate, pushing the U-shaped adjustable stop 5 to move in the transverse slide groove 3, thereby driving the retractable self-rebound placement pole 6 fixed at its upper end, as well as the laser emitting sensor 7 and the laser receiving sensor 8 to move, thus realizing the adjustment of the horizontal distance between them. At the same time, the vertical distance between the laser emitting sensor 7 and the laser receiving sensor 8 can be actively adjusted simultaneously. When the motor 9 is started, the roller rotating component 11 in the slot 16 of the outer end of the arc-shaped horizontal plate 10 rotates. The guide rail groove 12 on the inner side wall of the U-shaped adjustable stop 5 slides in cooperation with the arc-shaped horizontal plate 10 to ensure the stability and smoothness of the rotation. As the arc-shaped horizontal plate 10 rotates, its smooth curved gradually rising top surface 13 contacts the side opening of the U-shaped adjustable stop 5. Using the curve height of the smooth curved gradually rising top surface 13, the retractable self-rebound storage rod 6 is stretched and raised from the U-shaped adjustable stop 5, thereby adjusting the vertical distance between the laser emitting sensor 7 and the laser receiving sensor 8. At the same time, when the arc-shaped horizontal plate 10 rotates and pushes open the U-shaped adjustable stop 5, the symmetrical distance between the two in the horizontal direction is also adjusted. In the whole adjustment process, the various components cooperate with each other to ensure the accuracy and stability of the position adjustment of the laser emitting sensor 7 and the laser receiving sensor 8. The linkage adjustment in the vertical and horizontal directions further expands the adjustment range. This bidirectional adjustment mechanism enables the sensor to adapt to complex and ever-changing spatial detection scenarios, such as cargo detection in automated warehouses and irregular object contour detection. It can adjust the sensor position in all directions to meet the detection requirements of different angles, heights and distances, effectively improving the applicability and detection accuracy of the sensor.

[0028] Second implementation method:

[0029] Figure 1 , Figure 7This invention illustrates an active detection laser sensor. A sturdy base 14 is fixedly connected to the lower end of a vertical pole 2. Threaded pins 15 are symmetrically arranged on the front and rear sides of the upper end of the sturdy base 14. The vertical pole 2 is directly installed on a suitable base surface through the threaded pins 15 on the sturdy base 14. This installation method, independent of the equipment, isolates the vibration force generated by the equipment operation from the source. When the equipment vibrates during operation, the vibration cannot be transmitted to the sensors because the laser emitting sensor 7 and the laser receiving sensor 8 are not directly connected to the equipment. This ensures the stability of the sensor's position during detection, avoids detection errors caused by vibration, and improves the reliability of the detection data.

[0030] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
