Description

Technical Field

[0001] This utility model relates to the field of switch installation technology, and in particular to a magnetic fast positioning device for an infrared photoelectric switch on a vehicle scale. Background Technology

[0002] In truck scale systems, infrared switches primarily function as "vehicle position monitors" and "anti-cheating sentinels." Installed in pairs at both ends of the weighing platform, they form an invisible infrared light curtain to accurately detect whether vehicles are fully and correctly positioned on the platform, preventing weighing errors or data distortion caused by vehicles pressing against the edge or not fully mounting the scale. Simultaneously, this function effectively eliminates cheating behaviors such as incomplete weighing, ensuring the accuracy, reliability, and fairness of weighing data, and serving as a crucial guarantee for achieving automated and efficient weighing management.

[0003] The debugging of traditional truck scale infrared photoelectric switches relies heavily on manual experience to estimate the invisible infrared light path. Its calibration process has inherent defects such as low efficiency, insufficient accuracy, poor environmental adaptability and high safety risks. These shortcomings mainly stem from blind debugging caused by the invisible light path, lack of fast and reliable physical positioning benchmarks, and lack of effective auxiliary visual means when interfered with by rain, snow and strong light. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an infrared photoelectric switch magnetic fast positioning device for truck scales. Firstly, it improves debugging efficiency, significantly reducing the time required for a single debugging session and minimizing vehicle queuing and system interruptions. Secondly, it enhances calibration accuracy by using a precise visual reference provided by a visible light crosshair and a level to achieve stricter error control, improving the reliability of weighing data and system stability. Thirdly, it enhances environmental adaptability, effectively overcoming the bottleneck of traditional methods that struggle with reliable debugging in rain, snow, and strong light conditions, ensuring stable system operation in various harsh environments. Simultaneously, safety is fundamentally optimized, eliminating the need for operators to remain in the lane for extended periods, making the debugging process quick and safe, and reducing potential accident risks. Finally, these advantages translate into tangible economic benefits, effectively reducing fuel unloading losses and other indirect operating costs caused by debugging delays, achieving a win-win situation for safety, efficiency, and profitability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A vehicle scale infrared photoelectric switch magnetic fast positioning device includes a housing, magnetic bases fixedly connected to both sides of the housing, a visible light infrared coaxial crosshair emitter fixedly connected to the front end of the housing, and a biaxial bubble level installed on the top of the housing.

[0007] Furthermore, a mounting ring is fixedly connected to the front end of the visible light infrared coaxial crosshair emitter.

[0008] Furthermore, a light shield is slidably connected to the outer wall of the visible light infrared coaxial crosshair emitter, and multiple first magnetic blocks are fixedly connected to both sides inside the light shield. The first magnetic blocks are magnetically attracted to the mounting ring and the outer surface of the outer shell.

[0009] Furthermore, a second magnetic block is fixedly connected to the bottom of the biaxial bubble level, and the bottom of the second magnetic block is magnetically attached to the top of the outer casing.

[0010] Furthermore, a laser mode switching switch is installed on the upper front side of the housing.

[0011] This utility model has the following beneficial effects:

[0012] In this invention, magnetic bases located on both sides of the outer casing adhere to the outside of the mounting bracket, enabling rapid positioning and assembly / disassembly, thus shortening debugging time. A visible crossbeam is emitted from a visible infrared coaxial crossbeam emitter built into the casing, facilitating visual alignment and calibration. Simultaneously, a dual-axis bubble level integrated on the top provides a reliable horizontal reference, further ensuring calibration accuracy. The combination of magnetic fixation and multi-directional calibration significantly improves overall debugging efficiency and positioning accuracy. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3 This utility model provides an embodiment of an infrared photoelectric switch magnetic fast positioning device for a vehicle scale, comprising a housing 1, with magnetic bases 4 fixedly connected to both sides of the housing 1, and a visible light infrared coaxial crosshair emitter 3 fixedly connected to the front end of the housing 1. The visible light infrared coaxial crosshair emitter 3 is based on a coaxial common-path design of the optical path. Its core lies in integrating a high-brightness visible red laser beam with an invisible infrared beam through a special internal optical structure, ensuring that both are emitted precisely along the same path. A dual-axis bubble level 2 is installed on the top of the housing 1. The dual-axis bubble level 2 operates based on the principle of gravity and the tendency of bubbles in liquids to move towards the highest point. Its interior is a sealed cavity filled with liquid, with two sets of parallel, perpendicular markings engraved above the cavity. When the instrument is horizontal, the bubble will float in the center area of ​​the two sets of markings; if tilted in either direction, the bubble will deviate from the center due to gravity, thus visually indicating the horizontal deviation in that direction. By simultaneously observing the positions of bubbles in two vertical directions, the operator can perform precise leveling of the equipment. A laser mode switching switch 6 is installed on the upper front side of the housing 1. The laser mode switching switch 6 can switch the mode of the emitter. P is the pulse mode and CW is the constant light mode. The pulse mode is easier to be captured by the naked eye under strong light than the constant light mode, providing the operator with another option to enhance visibility.

[0022] Specifically, during operation, the entire device is first magnetically attached to the mounting bracket using the magnetic bases 4 on both sides of the outer casing 1, achieving rapid positioning. Then, the visible infrared coaxial crosshair emitter 3 is activated, emitting a visible crosshair laser beam coaxial with the invisible infrared light, providing a clear and visible centering reference. Simultaneously, the dual-axis bubble level 2 mounted on the top of the outer casing 1 monitors and adjusts the device's horizontal state, ensuring optical path calibration accuracy. The laser mode switch 6 allows switching the emitter's operating mode. The overall structure works synergistically to improve debugging efficiency and alignment accuracy, while reducing the impact of environmental interference.

[0023] Reference Figures 2 to 4 The front end of the visible light infrared coaxial crosshair emitter 3 is fixedly connected to the mounting ring 9. The outer wall of the visible light infrared coaxial crosshair emitter 3 is slidably connected to the light shield 5. Multiple first magnetic blocks 7 are fixedly connected to the two sides inside the light shield 5. The first magnetic blocks 7 are magnetically attracted to the mounting ring 9 and the outer surface of the outer shell 1. The bottom of the biaxial bubble level 2 is fixedly connected to the second magnetic block 8. The bottom of the second magnetic block 8 is magnetically attracted to the top of the outer shell 1.

[0024] Specifically, the mounting ring 9 at the front end of the visible infrared coaxial crosshair emitter 3 and the outer shell 1 provide an adsorption base for the light shield 5. The light shield 5 is adsorbed onto the light shield 5 by the first magnetic blocks 7 on both sides inside, allowing it to slide flexibly to adapt to different environments, effectively blocking stray light and reducing the impact of rain and snow, while improving the clarity of the visible crosshair. At the same time, the dual-axis bubble level 2 is adsorbed and fixed to the top of the outer shell 1 by the second magnetic block 8 at the bottom, ensuring a secure installation and allowing for adjustment of the installation position or removal for separate use as needed. This multi-magnetic design enhances the adjustment flexibility and ease of operation of each functional module, further improving the accuracy of calibration and its resistance to environmental interference.

[0025] Working Principle: First, the entire device is quickly and firmly attached to the photoelectric switch mounting bracket via the magnetic bases 4 on both sides of the outer casing 1. The visible light / infrared coaxial crosshair emitter 3 is then activated, emitting a visible crosshair laser coaxial with the infrared light, providing a visual reference for optical path alignment. The operator monitors the level using the dual-axis bubble level 2 on the top of the outer casing 1 and selects the emitter mode (P-pulse or CW constant light) via the laser mode switch 6. The light shield 5 is attached to the mounting ring 9 or the outer casing 1 via its internal first magnetic block 7, and can be slidably adjusted to block stray light and rain / snow interference, improving beam visibility. The dual-axis bubble level 2 is fixed to the outer casing 1 via the bottom second magnetic block 8, and can also be disassembled and used independently. The entire device, through its multi-magnetic structure and opto-mechanical collaborative design, achieves rapid assembly and adjustment, precise alignment, and resistance to environmental interference, significantly improving calibration efficiency and accuracy.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
