[0002] Existing vehicle body painting systems typically include key components such as a trolley for transporting the vehicle body, an oil tank, oil supply lines, an oil pump, and oil drums. The oil tank is cleverly positioned on the trolley for easy movement, meeting the paint supply needs of different work locations. The oil tank is connected to the oil drum via a carefully designed oil supply line, which serves as a channel for paint transfer, ensuring a smooth flow of paint from the drum to the tank. To pump paint from the drum to the tank, the system is equipped with an oil pump. Driven by a driving force, the pump delivers paint through the oil supply line to the tank. A level sensor is installed inside the oil tank to monitor the paint level in real time. This sensor accurately detects changes in the paint level, providing operators with timely paint replenishment information to ensure continuous operation.

[0003] However, in current system designs, oil drums are typically sealed to prevent paint evaporation, contamination, or leakage. This presents a problem: operators cannot directly know the remaining paint level in the drum. This not only inconveniences paint replenishment but may also lead to work interruptions due to insufficient paint, impacting efficiency. Therefore, how to accurately monitor the paint level in an oil drum in real time without compromising its airtightness has become a pressing technical problem to be solved in this field.

[0021] like Figure 1 and Figure 2 As shown, the present invention provides an oil replenishment device for a trolley oil box, including an oil box 1, an oil supply pipeline 2, an oil pump 3, an oil tank 4, and an electrical control system, wherein the electrical control system is electrically connected to the oil pump 3.

[0022] Oil box 1 is installed on the trolley. Oil box 1 is connected to oil drum 4 through oil supply line 2. Oil pump 3 is installed on oil supply line 2. Oil pump 3 can pump the paint in oil drum 4 to oil box 1 through oil supply line 2. A liquid level sensor is installed in oil box 1. A weight detection sensor is installed at the bottom of oil drum 4. The electrical control system is connected to the liquid level sensor and the weight detection sensor respectively.

[0023] Specifically, when the level sensor in oil tank 1 detects that the remaining paint level in oil tank 1 is below a certain threshold, it transmits a signal to the electronic control system. The electronic control system then controls oil pump 3 to pump the paint from oil drum 4 to oil tank 1 via oil supply pipeline 2. Similarly, when a weight detection sensor at the bottom of oil drum 4 detects that the remaining paint level in oil drum 4 is below a certain threshold, it also transmits a signal to the electronic control system to remind personnel to replenish paint in oil drum 4. In other embodiments, multiple oil drums 4 can be provided to achieve a backup protection effect.

[0024] In this embodiment, by setting a liquid level sensor in the oil box 1 and a weight detection sensor at the bottom of the oil drum 4, the remaining amount of paint in the oil box 1 and the oil drum 4 can be monitored in real time. This facilitates timely replenishment of paint in the oil box 1 and the oil drum 4, avoiding the impact of insufficient paint on the spraying work, and thus improving the efficiency and stability of the coating work.

[0025] The specific installation methods, working principles, and processes of the liquid level sensor, weight detection sensor, and electronic control system are all existing conventional knowledge, and therefore will not be elaborated upon here.

[0026] In one alternative embodiment, a miniature ultrasonic sensor is provided on the top of the oil drum 4, and the electronic control system is communicatively connected to the miniature ultrasonic sensor.

[0027] Specifically, a miniature ultrasonic sensor is a sensor that uses ultrasonic technology for non-contact ranging. It uses high-frequency sound waves to detect the position and distance of a target object and converts the signal into a processable electrical signal.

[0028] Miniature ultrasonic sensors offer advantages such as non-contact measurement, high precision and resolution, fast response, strong anti-interference capabilities, small size, and light weight. Adding a miniature ultrasonic sensor can further improve the measurement accuracy and precision of the paint content in the oil drum 4, effectively avoiding the inaccuracy or insufficient precision caused by monitoring solely with a weight sensor. In other embodiments, to further avoid the problem of insufficient detection precision and accuracy of a single sensor, detection devices such as infrared sensors can also be added.

[0029] In one optional embodiment, the oil supply line 2 is provided with a one-way check valve and a pressure relief micro-hole.

[0030] Specifically, in this embodiment, by providing a one-way check valve and a pressure relief micro-hole in the oil supply line 2, the oil circuit can be automatically cut off and the air pressure balanced when the machine stops, preventing paint backflow.

[0031] In one alternative embodiment, a display screen is provided on the outer wall of the oil box 1. The display screen is electrically connected to the electronic control system and is used to display the amount of paint inside the oil box 1 and the oil drum 4.

[0032] Specifically, in this embodiment, a display screen is provided on the outer wall of the oil box 1 to display the amount of paint inside the oil box 1 and the oil drum 4, so that the staff can intuitively observe the amount of paint inside the oil box 1 and the oil drum 4.

[0033] In one optional embodiment, an audible and visual alarm is provided on the outer wall of the oil box 1, and the audible and visual alarm is communicatively connected to the liquid level sensor and the weight detection sensor.

[0034] Specifically, in this embodiment, by setting up an audible and visual alarm and connecting it to a liquid level sensor and a weight detection sensor, an alarm can be issued in a timely manner when the liquid level sensor detects that the amount of paint in the oil container 1 is lower than a certain threshold or the weight detection sensor detects that the amount of paint in the oil drum 4 is lower than a certain threshold, so as to remind the staff to pay attention.

[0035] In one alternative embodiment, the oil drum 4 is equipped with a spiral stirring rod inside, which is driven by a micro motor, and the top of the spiral stirring rod is connected to the inner wall of the oil drum 4.

[0036] Specifically, in this embodiment, a spiral stirring rod is installed inside the oil drum 4 and driven by a micro motor. This spiral stirring rod stirs the paint inside the oil drum 4 to prevent paint sedimentation and thus maintain the pumping efficiency. The specific structure and installation method of the spiral stirring rod are existing technologies and will not be described in detail here.

[0037] In one optional embodiment, the oil supply line 2 is provided with a tapered contraction port and an air blowing port at its end.

[0038] Specifically, in this embodiment, a tapered contraction port and an air blowing port are provided at the end of the oil supply line 2, so that compressed air is introduced after the paint is touched up to remove the paint residue at the end of the oil supply line 2, thereby avoiding the paint residue at the end of the oil supply line 2 from causing blockage and ensuring that the oil supply line 2 can remain unobstructed when the paint is replenished.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
