Description

Technical Field

[0001] This utility model relates to the technical field of automotive pipeline cleaning equipment, specifically an induction cleaning device for cleaning automotive nylon pipeline assemblies. Background Technology

[0002] As a key connecting component in automotive fuel, braking, and cooling systems, the cleanliness of the inner wall of automotive nylon tubing directly affects the system's operational stability and lifespan. With the development of the automotive industry, nylon tubing, due to its lightweight and corrosion resistance, has gradually replaced traditional metal tubing as the mainstream choice. Correspondingly, tubing cleaning technology has evolved from manual cleaning to mechanically assisted cleaning. Early automotive nylon tubing cleaning relied on manual operation, using handheld brushes or cotton tools to wipe the inside of the tubing. This method was highly dependent on the operator's experience, resulting in uneven cleaning and ineffective cleaning of deep sections and bends, leading to incomplete cleaning. With the increasing demand for production automation, simple mechanical cleaning equipment emerged, using a motor-driven brush head to rotate and clean the inside of the tubing. However, such equipment lacks the ability to detect changes in the tubing's inner diameter and the state of dirt adhering to the inner wall. When the tubing has a variable diameter structure, the brush head may be too loosely attached to the tubing wall, resulting in inadequate cleaning, or too tightly attached, causing scratches on the inner wall of the nylon tubing.

[0003] In existing technologies, while some pipe cleaning equipment integrates sensing functions, they are mostly designed for large-diameter, low-precision applications such as ventilation ducts. Their sensing modules lack sufficient compatibility with the cleaning actuators, failing to meet the stringent requirements of automotive nylon tubing for cleaning precision and inner wall protection. Furthermore, existing equipment generally lacks real-time linkage control between sensing signals and cleaning actions, resulting in low cleaning efficiency and poor adaptability, making it difficult to meet the batch cleaning needs of multi-specification automotive nylon tubing assemblies.

[0005] To achieve the aforementioned goal of precise adaptation and efficient operation of the cleaning process through integrated sensing detection and intelligent drive control, this utility model provides the following technical solution: an inductive cleaning device for cleaning automotive nylon tubing assemblies, comprising a main frame, a three-sided enclosed cleaning chamber, an FFU cleaning mechanism, a time-delay sensing mechanism, an air path cleaning mechanism, and a central control mechanism; the three-sided enclosed cleaning chamber is fixed in the middle of the main frame, with the front of the chamber being an open working port and the remaining sides being enclosed; the top of the three-sided enclosed cleaning chamber is sealed to the FFU cleaning mechanism, and the bottom of the chamber is sealed to the air path cleaning mechanism; the time-delay sensing mechanism is fixed inside the three-sided enclosed cleaning chamber and located beside the conical air nozzle of the air path cleaning mechanism; the central control mechanism is embedded in the main frame and is connected to the FFU cleaning mechanism, the time-delay sensing mechanism, and the air path cleaning mechanism respectively.

[0006] Preferably, a transparent tempered glass observation window is fixed on the left side wall of the three-sided enclosed cleaning chamber, and silicone sealing strips are fixed at the joints of each enclosed surface of the three-sided enclosed cleaning chamber.

[0007] Preferably, the FFU clean unit includes a centrifugal fan, a HEPA high-efficiency filter, and an airflow equalization plate.

The centrifugal fan, HEPA high-efficiency filter, and airflow equalization plate are sequentially fixed inside the FFU clean unit, and the coverage area of ​​the airflow equalization plate is consistent with the cross-section of the three-sided enclosed clean chamber.

[0008] Preferably, the delay sensing mechanism includes an infrared diffuse reflection sensor and an L-shaped adjustment bracket. One end of the L-shaped adjustment bracket is fixed to the inner side wall of the three-sided enclosed cleaning chamber, and the infrared diffuse reflection sensor is fixed to the other end of the L-shaped adjustment bracket. The detection direction of the infrared diffuse reflection sensor is perpendicular to the axis of the conical air nozzle.

[0009] Preferably, the air path cleaning mechanism includes an upper fixed air blowing component and a lower negative pressure collection component. Both the upper fixed air blowing component and the lower negative pressure collection component are fixed vertically inside the three-sided enclosed cleaning chamber, and the upper fixed air blowing component is located directly above the lower negative pressure collection component.

[0010] Preferably, the upper fixed air blowing assembly includes an air source interface, a high-pressure air pipe, an electromagnetic airflow regulating valve, and a conical air nozzle. The air source interface is fixed on the outside of the main frame. One end of the high-pressure air pipe is connected to the air source interface, and the other end passes through the three-sided enclosed cleaning chamber and is connected to the input end of the electromagnetic airflow regulating valve.

[0011] Preferably, the conical nozzle has a 30° tapered angle gradient structure, the surface of the conical nozzle is engraved with an insertion depth scale, and the conical nozzle is coaxially arranged with the three-sided sealed cleaning chamber.

[0012] Preferably, the lower negative pressure collection assembly includes a funnel-shaped collection hood, a negative pressure air pipe, a negative pressure suction pump, and a sealed collection box. The large opening of the funnel-shaped collection hood is sealed to the bottom of the three-sided enclosed cleaning chamber.

[0015] Compared with the prior art, this utility model provides an induction cleaning device for cleaning automotive nylon hose assemblies, which has the following beneficial effects: 1. This sensor-operated cleaning device for cleaning automotive nylon piping assemblies, through the cooperation of a three-sided enclosed cleaning chamber and an FFU (Fan Filter Unit) cleaning mechanism, allows the HEPA-grade clean airflow output by the FFU to vertically cover the cleaning chamber downwards, forming an airflow barrier at the work inlet. This effectively blocks external dust from entering, ensuring that the dust concentration inside the cleaning chamber is ≤0.3mg / m³, thus solving the problem of secondary contamination of piping caused by the lack of a clean environment in existing equipment.

[0016] 2. This sensor-operated cleaning device for cleaning automotive nylon hose assemblies uses a tapered nozzle with a 30° tapered angle gradient structure. It can adapt to nylon hoses with diameters of 6-25mm without changing any parts, making it widely compatible. The three-sided enclosed cleaning chamber has an open front with ample hand space, allowing operators to directly hold the hose and insert it into the nozzle. The depth markings on the nozzle surface greatly reduce the difficulty of alignment. A single person can clean 8-10 hoses per minute, which is 4-5 times more efficient than traditional manual cleaning. Moreover, no professional training is required to operate it, reducing labor costs.

[0017] 3. This induction-type cleaning device for cleaning automotive nylon hose assemblies uses a side-mounted infrared diffuse reflection sensor with a delay sensing mechanism. It detects a valid signal only when the hose wraps around the nozzle end by ≥8mm, and triggers the cleaning action after a delay of 0.5-1 seconds to avoid misoperation. At the same time, the central control mechanism fixes the blowing time to 6-8 seconds to ensure that the cleaning time of each hose is consistent, the cleaning effect is uniform, and the trigger accuracy and cleaning consistency both reach 100%, which solves the defects of low trigger accuracy and unstable cleaning effect of existing equipment.

[0018] 4. This sensor-operated cleaning device for cleaning automotive nylon piping assemblies completely covers the area where impurities are scattered through the funnel-shaped collection hood of the lower negative pressure collection component. Combined with a -0.08MPa negative pressure suction pump and an FFU cleaning mechanism to assist in the sedimentation of impurities, the impurity collection rate is ≥99%. The sealed collection box can centrally store impurities, preventing debris from scattering and polluting the workshop environment. No additional manpower is required for cleaning, reducing workshop cleaning costs by 30% compared to existing equipment, while also preventing impurities from re-entering the piping.

[0028] Working Principle: The operator connects the main power supply to the equipment, the central control mechanism 6 starts, and the FFU cleanroom 3 begins operation. Airflow, after being filtered by the HEPA high-efficiency filter 32, is evenly distributed by the airflow equalization plate 33 and enters vertically downwards into the three-sided enclosed cleaning chamber 2, forming an airflow barrier at the open working opening. The negative pressure suction pump 523 enters a low-power standby state. The operator confirms or adjusts parameters via the 1.5-inch touchscreen, and the equipment enters standby mode. The operator holds the automotive nylon hose to be cleaned and passes it through the open opening at the front of the three-sided enclosed cleaning chamber 2. The working port extends into the chamber. Through the transparent tempered glass observation window 21, the pipe opening is aligned with the conical nozzle 512. Guided by the 30° cone angle of the nozzle 512, the pipe is slowly inserted until the insertion depth reaches more than 8mm of the insertion depth scale. After the infrared diffuse reflection sensor 41 of the delay sensing mechanism 4 detects that the pipe wraps around the end of the conical nozzle 512 by ≥8mm, it sends a valid signal to the central control mechanism 6. After receiving the signal, the central control mechanism 6 delays for 0.8 seconds and sends an opening command to the electromagnetic airflow regulating valve 514. Simultaneously, a full-load operation command is sent to the negative pressure suction pump 523; after the electromagnetic airflow regulating valve 514 is opened, the high-pressure airflow enters the pipeline through the high-pressure air pipe 513 and the conical air nozzle 512, stripping the injection molding debris and dust from the inner wall of the pipeline; the clean airflow generated by the FFU clean unit 3 assists the impurities to settle downwards, and the negative pressure generated by the negative pressure suction pump 523 draws the impurities in through the funnel-shaped collection hood 521, and into the sealed collection box 524 through the negative pressure air pipe 522; after the purging time reaches 7 seconds, the central control mechanism 6 sends a command to the electromagnetic airflow regulating valve 514. 4. Send a shutdown command, and the airflow stops spraying; at the same time, to ensure that residual impurities are completely collected, the negative pressure suction pump 523 continues to run at full load for 5 seconds before returning to low-power standby mode; the operator pulls the cleaned pipeline out of the conical nozzle 512 to complete the cleaning of a single pipeline; when the impurities in the sealed collection box 524 reach the scale line displayed in the transparent observation window, the operator turns off the power of the equipment, opens the quick drain port of the sealed collection box 524, cleans the internal impurities, and restarts the equipment to continue the cleaning operation.

[0029] In summary, this sensor-based cleaning device for cleaning automotive nylon tubing assemblies provides stable support for each mechanism through the main frame 1. The three-sided enclosed cleaning chamber 2, together with the FFU cleaning mechanism 3, creates a clean environment to avoid secondary pollution. The delayed sensing mechanism 4 enables precise triggering and prevents misoperation. The upper end of the air path cleaning mechanism 5 has a fixed air blowing component 51 that adapts to multiple specifications of tubing, while the lower end has a negative pressure collection component 52 that thoroughly collects impurities. The central control mechanism 6 links all mechanisms to ensure the automation and standardization of the cleaning process.
