Description

Technical Field

[0001] This utility model is an oil mist lubricator that can monitor oil volume and level, belonging to the field of oil mist lubricator technology. Background Technology

[0002] Oil mist lubricators are the "core of lubrication assurance" in pneumatic systems. They atomize liquid lubricating oil into a fine mist of 5-10μm using compressed air, which is then delivered by the airflow to components such as cylinders, pneumatic valves, and pneumatic tools. This forms an oil film on the surfaces of pistons, seals, and valve cores, preventing wear caused by dry friction. Their applications cover the entire industrial sector: pneumatic robotic arms on automotive production lines, pneumatic wrenches in hardware workshops, and pneumatic conveyor belts in food factories all rely on oil mist lubricators to maintain stable operation. However, ordinary oil mist lubricators often lack oil level monitoring, leading to the problem of "oil running out unnoticed"—workers are too busy to observe the transparent oil cup, and by the time they notice the pneumatic components are stuck, the components have already been damaged by dry friction. To address this pain point, "oil mist lubricators that can monitor oil levels" have appeared on the market.

[0003] However, existing products still have shortcomings such as low monitoring accuracy and single alarm: for example, float-type oil level gauges are easily stuck by oil, and capacitive sensors are greatly affected by oil quality and have large detection deviations. They can only "alarm low oil" and cannot display the percentage of remaining oil. Workers still need to frequently stop the machine to check, which does not fundamentally solve the maintenance efficiency problem. There is an urgent need for an oil mist lubricator that can monitor oil volume and level to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an oil mist lubricator that can monitor oil level and volume, thereby solving the problems mentioned in the background section. This invention employs a laser positioning feedback structure in conjunction with a micro screw drive, enabling real-time monitoring of the oil level in the oil mist lubricator and simultaneously feeding back the remaining oil percentage to an LCD screen.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an oil mist lubricator for monitoring oil volume and level, comprising an oil mist lubricator body, an arc-shaped cover, and an LCD screen. An oil mist lubricator storage section is installed at the lower end of the oil mist lubricator body, and an embedded transparent glass is embedded at the front end of the oil mist lubricator storage section. The arc-shaped cover is installed at the front end of the oil mist lubricator storage section and covers the embedded transparent glass. A push-button switch is embedded on the lower right side of the arc-shaped cover. A small bearing is installed at the lower end of the arc-shaped cover. A small motor is installed at the upper end of the arc-shaped cover. A miniature screw is installed at the shaft end of the small motor. An internal threaded ring is threaded onto the external side of the miniature screw, and an arc-shaped guide plate is installed outside the internal threaded ring. A sensor holder is installed at the rear end of the arc-shaped guide plate, and a laser displacement sensor is inserted into the sensor holder. The LCD screen is installed at the front end of the oil mist lubricator body, and a buzzer and a microcontroller are respectively installed on the left and right sides of the lower end of the LCD screen.

[0006] Furthermore, the micro-screw is located within an arc-shaped cover, and its lower end is mounted within a small bearing.

[0007] Furthermore, the arc-shaped guide plate is slidably located within the arc-shaped cover.

[0008] Furthermore, the detection end of the laser displacement sensor is directly facing the embedded transparent glass.

[0009] Furthermore, the LCD screen, push-button switch, small motor, laser displacement sensor, microcontroller, and buzzer are connected to an external power source via wires.

[0010] Furthermore, a transparent film is attached to the front surface of the LCD screen.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an oil mist lubricator that can monitor oil level. Because it incorporates an embedded transparent glass, an LCD screen, an arc-shaped cover, a push-button switch, a small motor, a micro screw, a small bearing, an arc-shaped guide plate, a laser displacement sensor, a microcontroller, and a buzzer, its structure is reasonable. The use of a laser positioning feedback structure combined with a micro screw drive enables real-time monitoring of the oil level in the oil mist lubricator. Simultaneously, it provides feedback to the LCD screen to display the remaining oil percentage in real time. Furthermore, the push-button switch provides feedback and an alarm when the oil level is low, providing an audible reminder to staff. This makes it highly practical. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: an oil mist lubricator for monitoring oil level, comprising an oil mist lubricator body 1, an arc-shaped cover 5, and an LCD screen 4. An oil mist lubricator reservoir 2 is installed at the lower end of the oil mist lubricator body 1, and an embedded transparent glass 3 is embedded at the front end of the oil mist lubricator reservoir 2. The arc-shaped cover 5 is installed at the front end of the oil mist lubricator reservoir 2 and covers the outside of the embedded transparent glass 3. A push-button switch 6 is embedded on the lower right side of the inside of the arc-shaped cover 5. A small bearing 9 is installed at the lower end of the arc-shaped cover 5, and a small motor 7 is installed at the upper end of the arc-shaped cover 5. A miniature screw 8 is installed on the shaft end of the motor 7. An internal threaded ring is installed on the outside of the miniature screw 8 through a thread, and an arc-shaped guide plate 10 is installed on the outside of the internal threaded ring. A sensor holder 11 is installed at the rear end of the arc-shaped guide plate 10. A laser displacement sensor 12 is inserted into the sensor holder 11. An LCD screen 4 is installed at the front end of the oil mist lubricator body 1. A buzzer 15 and a microcontroller 13 are respectively installed on the left and right sides of the lower end of the LCD screen 4. This design solves the problems of low monitoring accuracy and single alarm of the existing "oil mist lubricators that can monitor oil volume and liquid level" on the market.

[0020] As the first embodiment of this utility model: the miniature screw 8 is located inside the arc-shaped cover 5, and its lower end is installed in the small bearing 9. The addition of the small bearing 9 ensures that the miniature screw 8 remains stable when rotating, reducing shaking and wear.

[0021] The arc-shaped guide plate 10 slides inside the arc-shaped cover 5. With the addition of the arc-shaped guide plate 10, the laser displacement sensor 12 can move smoothly along the arc-shaped trajectory, adapting to the arc-shaped structure of the oil mist lubricator oil storage section 2.

[0022] The detection end of the laser displacement sensor 12 faces the embedded transparent glass 3. The added embedded transparent glass 3 enables the laser to penetrate and accurately detect the position of the oil surface, avoiding the impact of oil stains or structural obstruction on measurement accuracy.

[0023] The LCD screen 4, push-button switch 6, small motor 7, laser displacement sensor 12, microcontroller 13, and buzzer 15 are connected to an external power source via wires. The added microcontroller 13 enables signal processing, data calculation, and system control, ensuring that all components work in coordination.

[0024] A transparent film 14 is attached to the front surface of the LCD screen 4. The added transparent film 14 protects the LCD screen 4 from dust, oil or mechanical scratches and extends its service life.

[0025] In the second embodiment of this utility model: when the oil mist lubricator is working, the microcontroller 13 controls the small motor 7 to start, driving the micro screw 8 to rotate. Through threaded transmission, the arc-shaped guide plate 10 slides up and down along the arc-shaped cover 5. The laser displacement sensor 12 moves with the arc-shaped guide plate 10, emitting laser light in real time through the embedded transparent glass 3 to detect the oil level position and feeding back the displacement signal to the microcontroller 13. The microcontroller 13 calculates the remaining oil percentage based on the displacement signal and displays it in real time on the LCD screen 4. When the oil level drops to a preset threshold, the microcontroller 13 controls the small motor 7 to start, driving the micro screw 8 to rotate, forcing the arc-shaped guide plate 10 to move to the bottom of the arc-shaped cover 5, triggering the push-button switch 6. The microcontroller 13 then activates the buzzer 15 to sound an alarm, reminding staff to refuel in time. During this process, the LCD screen 4 displays the percentage of remaining oil calculated and fed back by the laser displacement sensor 12 through the microcontroller 13 in real time, allowing staff to observe in real time. In addition, all standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
