Description

Technical Field

[0001] The invention relates to a miniaturized automatic pressurized flushing device and a flushing method, belonging to the technical field of precision cleaning. Background Art

[0002] The problem of excess material is the main reason that affects the qualification rate of the instrument. After the float of the liquid-floating inertial instrument is bonded to the jewel pad and the jewel bearing, a gap is inevitably generated, and floating oil and impurities are easily infiltrated into the gap. Due to the high viscosity of the floating oil, it is difficult to clean. The process requires that the gap of the jewel bearing be thoroughly cleaned before the whole meter is assembled. Since the jewel bearing hole is less than 1mm, the current method requires the operator to repeatedly clean the jewel bearing hole under a 20x microscope, mainly relying on tools such as syringes and brushes, and then use an air gun to blow and clean. The cleaning efficiency of the entire process is low, and repeated operations are required. There is a possibility that the cleaning is not thorough. In theory, micron-level excess material in the gap will also affect the accuracy of the instrument. Summary of the invention

[0007] The automatic pressurized flushing system delivers the cleaning agent that meets the cleanliness requirements to the flushing head, and performs pressurized flushing on the instrument to be flushed placed on the rotating table. During the flushing process, the system simultaneously receives feedback from the particle size detection system to indicate whether the particle size requirements have been met. When the particle size requirements have been met, the system stops flushing.

[0008] The particle size detection system is used to detect whether the cleaning agent in the cleaning agent cleaning filter system meets the cleanliness requirements before the automatic pressurized flushing system is turned on for flushing, and to detect whether the cleanliness of the cleaning agent on the rotating table meets the particle size requirements during the flushing process of the automatic pressurized flushing system.

The outlet is connected to the small-displacement gear pump and the clean tank respectively, and the pumped cleaning agent is transported to the clean tank through the pipeline for storage;

[0013] The pressure reducing valve is connected to a large displacement gear pump, and the output end and the output end of the small displacement gear pump are connected to a particle size detection system;

[0017] The rotating table is connected to the particle size detector through the second gate valve, and the particle size detector has a built-in pump body;

[0018] Before flushing, open the first gate valve, close the second gate valve and the third gate valve, and the cleaning agent in the clean tank is pumped to the particle size detector by a small displacement gear pump. The particle size detector detects whether the cleaning agent meets the cleanliness requirements;

[0019] Close the first gate valve, open the second gate valve and the third gate valve, and the cleaning agent in the clean tank is pumped to the automatic pressurized flushing system by the pressure reducing valve and the small displacement gear pump. The automatic pressurized flushing system performs flushing, and the particle size detector extracts the cleaning agent on the rotating table to detect whether the cleaning agent meets the particle size requirements.

[0020] Furthermore, the particle size detector is connected to the container tank, and the cleaning agent after cleaning is extracted and discharged back into the container tank, thereby realizing the repeated use of the cleaning agent.

[0021] Furthermore, the large displacement gear pump is a micro gear pump with a displacement of 2 ml / r to 10 ml / r, which is used to reduce the overall volume of the container tank.

[0022] Furthermore, the displacement of the small displacement gear pump is 0.2 ml / r to 1 ml / r.

[0023] Furthermore, the automatic pressurized flushing system includes a diverter, two flushing heads, and a feed system;

[0024] The flow divider divides the cleaning agent that meets the cleanliness requirements and is transported by the pipeline into two equal paths, each of which is connected to a flushing head;

[0025] Two flushing heads are placed on the feed system and separated on both sides of the instrument to be flushed. Holes are opened on the flushing heads with a diameter of 0.1mm to 0.3mm, and cleaning agents are sprayed out to flush the instrument under pressure.

[0026] The feeding system moves the two flushing heads symmetrically and adjusts the distance and angle between the flushing heads and the products being cleaned.

[0027] Furthermore, the feeding system includes a bidirectional slide and a stepper motor; two flushing heads are placed on the bidirectional slide, and the stepper motor drives the bidirectional slide to slide.

[0028] Furthermore, the instrument to be flushed is placed on a rotating table, and elastic baffles are respectively installed on both sides of the rotating table to fix the instrument to be flushed and alleviate the impact on the instrument to be flushed during flushing.

[0031] Step 2: Run the cleaning agent clean filtration system and use a particle size detector to detect the cleanliness of the cleaning agent. When the condition that the particles larger than 1 μm are not larger than 100 / 10ML is not met, the cleaning agent clean filtration system is continuously run; when the condition that the particles larger than 1 μm are not larger than 100 / 10ML is met, the cleaning agent clean filtration system is automatically stopped and the cleaning agent is considered clean;

[0032] Step 3: Run the automatic pressurized flushing system, and monitor the particle size of the cleaning agent after cleaning detected by the particle size detector in real time during the flushing process.

[0042] Figure 2 This is a flow chart of the flushing method of the miniaturized automatic pressurized flushing equipment according to an embodiment of the present invention. DETAILED DESCRIPTION

[0043] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] The invention provides a miniaturized automatic pressurized flushing device, which comprises a cleaning agent clean filtering system, an automatic pressurized flushing system and a particle size detection system.

[0045] The cleaning agent clean filtration system filters the cleaning agent and outputs the cleaning agent that meets the cleanliness requirements to the automatic pressurized flushing system through pipelines. Figure 1 As shown, the cleaning agent clean filtration system includes a container tank 1, a filter 2, a large-displacement gear pump 3, a small-displacement gear pump 6, a clean tank 4, and a third gate valve 10.

[0046] The cleaning solvent is stored in a container tank 1, which is connected to a filter 2 through a pipeline. The filter 2 is used to filter the cleaning solvent. The filtering accuracy is selected to be 0.2 μm to ensure the cleanliness of the solvent.

[0047] The inlet of the large displacement gear pump 3 is connected to the filter, and the cleaning solvent in the container tank 1 is extracted under pressure to pass through the filter 2 to achieve the filtering purpose. The outlet is respectively connected to the pressure reducing valve 5, the small displacement gear pump 6 and the clean tank 4. In this embodiment, the large displacement gear pump 3 uses a micro gear pump to reduce the overall volume of the cleaning agent processing box. The displacement of the large displacement gear pump is 2-10 ml / r, which realizes the two purposes of extracting the cleaning agent in the container tank and pumping it out to the clean tank 4.

[0048] The clean tank 4 is used to store the cleaning liquid pumped out by the large-displacement gear pump. The clean tank 6 is well sealed to reduce the pollution of the external environment to the cleaning agent in the clean tank. The pressure reducing valve is used to reduce the pressure of the cleaning agent in the pipeline. The pressure is set to 0.6MPa to avoid excessive pressure from causing a large impact on the cleaning product. The small-displacement gear pump 6 is used to pump the cleaning liquid in the clean tank 4 into the diverter 11 through the third gate valve. In this embodiment, the displacement of the small-displacement gear pump 6 is 0.2-1ml / r.

[0049] The automatic pressurized flushing system delivers the cleaning agent that meets the cleanliness requirements to the flushing head, and performs pressurized flushing on the instrument to be flushed placed on the rotating table. During the flushing process, the particle size detection system simultaneously receives feedback from the particle size detection system to indicate whether the particle size requirements have been met. When the particle size requirements have been met, the flushing is stopped. The automatic pressurized flushing system includes a diverter 11, a flushing head 16, and a feeding system. In this embodiment, the feeding system includes a bidirectional slide 13 and a stepper motor 12.

[0050] The flow divider 7 is used to divide the main cleaning line into a left line and a right line, and deliver the cleaning agent to the left flushing head and the right flushing head 16 to ensure that the flow rates of the left flushing head and the right flushing head 16 are consistent.

[0051] Two flushing heads 16 are used to spray cleaning agents to achieve a cleaning effect. The flushing heads 16 are aligned with the jewel bearing holes of the float assembly, and the flushing heads 16 are coaxial with the jewel bearing holes through the structure; a small hole is opened on the flushing head 16 to achieve a straight line spray of the solvent from the hole; the hole diameter of the flushing head 16 is 0.1-0.3 mm.

[0052] The bidirectional slide 13 is connected to the stepper motor 12, and the flushing head 16 can be symmetrically moved to adjust the flushing distance and realize the adjustment of the position of the flushing head 16. The unidirectional range of the bidirectional slide 13 is 30 mm.

[0053] The rotating platform 14 is used to install the float assembly to be cleaned, and realizes the functions of fixing the float assembly and washing at a slight angle. An elastic baffle 15 is installed on the rotating platform 14 to fix the float assembly and alleviate the impact on the float assembly during washing. In this embodiment, the minimum rotation angle of the rotating platform 14 is 0.1°, which is used to adjust the washing angle of the washing head 16.

[0054] The particle size detection system is used to detect whether the cleaning agent in the cleaning agent clean filter system meets the cleanliness requirements before the automatic pressurized flushing system is turned on for flushing, and to detect whether the cleanliness of the cleaning agent on the rotating table meets the particle size requirements during the flushing process of the automatic pressurized flushing system. The particle size detection system includes a particle size detector 7, a first gate valve 8, and a second gate valve 9.

[0055] The particle size detector 7 is connected to the valve body and the container tank 1 through a pipeline, and is used to extract the cleaning agent on the rotating table 14, perform real-time particle size detection on the cleaning agent, and evaluate the cleaning effect. The particle size detector 7 is equipped with a pump body, which is used to extract the cleaning agent for cleaning the float assembly; the particle size detector 7 supports online and offline detection functions. The online function is used to implement the detection of the cleaning agent after cleaning, and the recognition accuracy is 1μm. When the particles larger than 1μm are not more than 100 / 10ML, the cleaning process is deemed to be completed and the flushing is automatically stopped. The offline function is used to detect the particle size of the cleaning agent used to flush the float assembly in the container tank to ensure the cleanliness of the cleaning agent; the particle size detector 7 is connected to the container tank, and is used to extract the cleaning agent after cleaning and discharge it back into the container tank, so as to realize the repeated use of the cleaning agent.

[0056] When the clean filtration system is running, the first gate valve 8 is opened, and the second gate valve 9 and the third gate valve 10 are closed. The cleaning agent stored in the container tank is drawn to the filter 2 through the pipeline by the large-displacement gear pump 3 to filter the cleaning agent, and then the cleaning agent is pumped out to the clean tank 4 by the large-displacement gear pump 3. The cleaning agent in the clean tank 4 is pumped to the particle size detector 7 by the small-displacement gear pump 6 to detect the particle size, and finally discharged back to the container tank.

[0057] When the automatic pressurized flushing system is running, the second gate valve 9 and the third gate valve 10 are started, and the first gate valve 8 is closed. The cleaning agent stored in the container tank is extracted to the filter through the pipeline by the large-displacement gear pump to filter the cleaning agent, and then pumped out to the clean tank 4 by the large-displacement gear pump. The cleaning agent in the clean tank 4 is pumped to the diverter 11 by the small-displacement gear pump 6, and then diverted by the diverter 11 and sprayed out by the left and right flushing heads 16 for flushing. During the cleaning process, the cleaning agent is extracted by the built-in pump of the particle size detector 7 and pumped back into the container tank.

[0058] The method flow for flushing the instrument based on this equipment is as follows Figure 2 As shown, including:

[0059] Step 1: Install the float assembly to the rotating platform 14 and use the elastic baffle 15 to fix the float assembly.

[0060] Step 2: Start the power supply of the miniaturized automatic pressurized flushing equipment.

[0061] Step 3, run the cleaning agent clean filtration system, use the particle size detector 7 to detect the particle size of the cleaning agent in the container tank, when the condition that the particles larger than 1 μm are no more than 100 / 10ML is not met, continue to run the cleaning agent clean filtration system; when the condition that the particles larger than 1 μm are no more than 100 / 10ML is met, automatically stop the cleaning agent clean filtration system, and it is considered that the cleaning agent is clean.

[0062] Step 4: Run the automatic pressurized flushing system and monitor the particle size of the cleaning agent after cleaning detected by the particle size detector in real time during the flushing process. When the condition that the particles larger than 1 μm are no more than 100 / 10ML is not met, continue to run the automatic pressurized flushing system and the feeding system; when the cleaning agent particle size meets the condition that the particles larger than 1 μm are no more than 100 / 10ML, automatically stop the automatic pressurized flushing system and the feeding system to end the flushing.

[0063] Step 5. Remove the float assembly and complete the flushing.

[0064] The equipment can realize automatic pressure flushing of the jewel bearing hole of the float assembly, and the real-time particle size detection of the cleaning agent can be realized through the particle size detection module. After the flushing effect reaches the index, the flushing will be automatically stopped, and the cleaning agent will be filtered through the filter to ensure the cleanliness of the cleaning agent. The equipment can be extended to other component cleaning, especially the cleaning of deep holes or small gap structures, to realize automatic pressure flushing of the jewel bearing hole, reduce the risk of excess materials in the liquid floating inertial instrument, and improve the qualification rate of the instrument.

[0065] The above-described embodiments are only preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
