Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a solenoid valve cleaning device. Background Technology

[0002] During the production of automotive component solenoid valves, the valves undergo oil circuit pressure and flow tests to ensure their performance meets relevant standards. However, after this test, a large amount of oil often remains inside and on the surface of the solenoid valve body. This residual oil not only affects the cleanliness requirements of the solenoid valve during subsequent assembly processes but may also adversely affect its normal use and performance.

[0003] Currently, the main method used in production processes is static settling to remove residual oil from the surface of solenoid valves. However, this method has several drawbacks. First, static settling requires a long time, which significantly reduces production efficiency and fails to meet the demands of modern industrial production for high efficiency and speed. Second, because the residual oil inside and on the surface of the valve body has a certain viscosity, it is difficult to thoroughly clean it by static settling alone, resulting in poor cleaning effects. Furthermore, with the shortening of equipment cycle times, static settling accumulates a large number of buffer parts, further increasing the time for cleaning and first-piece production, further impacting production efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a solenoid valve cleaning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the time-consuming and inefficient static method for removing residual oil from solenoid valves, incomplete cleaning, and the accumulation of buffer components, which can easily affect overall production efficiency. Therefore, this invention proposes a solenoid valve cleaning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A solenoid valve cleaning device, comprising:

[0008] A fixed frame, wherein an air blowing hood and multiple air needles are fixedly installed inside the fixed frame, and the multiple air needles are all connected to an external air pump;

[0009] A transfer slide, which is slidably mounted on the bottom of a fixed frame via guide rails, is used to place and move multiple solenoid valve bodies;

[0010] The multiple air needles cooperate with the air blowing hood to spray high-pressure gas onto the surface and internal channels of the solenoid valve body when the transfer slide moves to the cleaning position, so as to efficiently flush away residual oil.

[0011] In one possible design, a housing is fixedly mounted on the outer wall of the fixed frame, and the housing has multiple openings on the side near the transfer slide to allow the transfer slide and the solenoid valve body to enter and exit.

[0012] In one possible design, a plurality of positioning seats are fixedly mounted on the top of the transfer slide, and the plurality of positioning seats are used to position and fix the solenoid valve body.

[0013] In one possible design, a photoelectric sensor is provided on one side of the fixed frame. The photoelectric sensor is fixedly installed by an external bracket and cooperates with multiple positioning seats to detect the installation of the solenoid valve body.

[0014] In one possible design, a drive cylinder is provided on one side of the fixed frame, and one end of the piston rod of the drive cylinder is fixedly connected to one side of the transfer slide for horizontally driving the transfer slide.

[0015] In one possible design, a baffle is fixedly installed on one side of the transfer slide. The baffle is used to block the opening of the housing after the transfer slide moves into the housing, preventing airflow leakage.

[0016] In this application, during use, the operator places the solenoid valve bodies, which have undergone oil circuit pressure and flow testing and have residual oil on their surface and inside, one by one onto the positioning seat on top of the transfer slide. The positioning seat ensures that the solenoid valve body is securely positioned and fixed.

[0017] Then, the photoelectric sensor located on one side of the fixed frame detects that the solenoid valve body on the positioning seat has been correctly placed. After confirming the detection signal, the operator can press the external start button.

[0018] Upon receiving the start signal, the drive cylinder on one side of the fixed frame actuates, retracting its piston rod. The piston rod then moves the transfer slide along the guide rail at the bottom of the fixed frame into the equipment, smoothly transporting the transfer slide carrying the solenoid valve body to the preset cleaning position. During this process, a baffle on one side of the transfer slide moves in with the slide and engages with the opening on the outer casing to form a barrier, preventing airflow leakage during subsequent cleaning processes from affecting the operating environment.

[0019] When the transfer slide accurately reaches the preset cleaning position, multiple solenoid valve bodies are positioned within their respective air blowing hoods. The equipment control system then triggers a cleaning command. At this point, multiple air needles open simultaneously. These needles, connected to an external air pump, precisely spray high-pressure gas onto the surface of the solenoid valve body and the internal channels requiring cleaning. The combined action of these air needles and the corresponding air blowing hoods creates effective airflow coverage, ensuring efficient flushing of residual oil from the surface and interior of the solenoid valve body.

[0020] The high-pressure gas purging will continue for a predetermined period of time (approximately 20 seconds). This duration is sufficient to ensure that residual oil inside and on the surface of the solenoid valve body is completely purged, achieving the required cleanliness standard.

[0021] After the preset purging time is reached, the control system automatically shuts off the air supply, stopping the air supply to the air needle. Then, the piston rod of the drive cylinder extends again, pushing the transfer slide to move in the opposite direction along the guide rail, smoothly transporting the transfer slide carrying the cleaned solenoid valve body back to its initial loading position from inside the equipment. Once the transfer slide has fully reset, the operator can remove the cleaned solenoid valve body from the positioning seat. Repeating the above steps allows for continuous and efficient cleaning of subsequent solenoid valve bodies.

[0022] Beneficial effects: In this utility model, the solenoid valve cleaning device, by setting multiple air needles and corresponding air blowing hoods, can accurately spray high-pressure gas onto the surface of the solenoid valve body and the internal channels that need to be cleaned in a short time, forming an effective airflow coverage, thereby ensuring efficient flushing of residual oil on the surface and inside of the solenoid valve body; compared with the traditional static cleaning method, this device greatly shortens the cleaning time and improves the cleaning efficiency.

[0023] In this invention, the solenoid valve cleaning device, through the synergistic effect of the air needle and the air blowing hood, and the powerful flushing force of the high-pressure gas, can remove residual oil inside and on the surface of the solenoid valve body to the greatest extent, achieving the required cleanliness standard; this avoids the problem of incomplete cleaning caused by the viscosity of residual oil in the static cleaning method, and ensures the cleanliness requirements of the solenoid valve in the subsequent assembly process.

[0024] In this invention, the solenoid valve cleaning equipment, by adopting an automated transfer slide design, can quickly and smoothly transport the solenoid valve body to the preset cleaning position, and quickly transport it back to the initial loading position after cleaning; this greatly shortens the dwell time of the solenoid valve during the cleaning process, reduces the number of buffer parts, thereby reducing the time for cleaning and first-piece production, and improving the overall efficiency of the production line.

[0025] In this invention, the solenoid valve cleaning device detects the installation status of the solenoid valve body through a photoelectric sensor and automatically triggers a cleaning command after confirming the detection signal. The operator only needs to place the solenoid valve body on the positioning seat and press the start button to complete the entire cleaning process, which greatly simplifies the operation process, reduces the difficulty of operation, and improves work efficiency.

[0026] In this utility model, the solenoid valve cleaning device has a baffle on one side of the transfer slide to block the opening on one side of the housing after the transfer slide moves into the housing; this effectively prevents the airflow leakage during the cleaning process from affecting the operating environment and ensures the safety of the operators.

[0027] In this invention, the solenoid valve cleaning equipment uses multiple air needles in conjunction with an air blowing hood to precisely and efficiently flush away residual oil inside and outside the solenoid valve body, significantly shortening cleaning time and improving efficiency. A photoelectric sensor automatically detects the placement of the solenoid valve body, ensuring stable operation. The automated transfer slide design allows for rapid and stable transport of the solenoid valve body, reducing buffer components and cleaning time. Furthermore, the baffle design effectively prevents air leakage, ensuring operator safety. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] In one embodiment: Refer to Figure 1-3 A cleaning device includes: a fixed frame 1, a transfer slide 3, and multiple components that cooperate with it, for cleaning the solenoid valve body 5.

[0034] In this embodiment, the fixed frame 1 serves as the supporting structure for the entire device. Inside, a blowing hood 8 and multiple air needles 9 are securely mounted via specific brackets. The installation positions of the blowing hood 8 and air needles 9 are carefully designed to ensure effective air-blowing cleaning of the solenoid valve body 5. Specifically, each air needle 9 is connected to an external air pump. When the air pump is activated, compressed air is ejected through the air needles 9. The air needles 9 cooperate with the corresponding blowing hood 8 to form specific airflow channels, allowing the airflow ejected from the air needles 9 to accurately act on the solenoid valve body 5 to be cleaned, thereby blowing off oil, impurities, and other contaminants from the surface of the solenoid valve body 5, achieving the cleaning purpose.

[0035] To facilitate the placement and movement of multiple solenoid valve bodies 5, a transfer slide 3 is also provided in this embodiment. The transfer slide 3 is slidably mounted on the bottom inner wall of the fixed frame 1 via guide rails. The guide rails ensure the stability and accuracy of the transfer slide 3 during movement. In actual operation, the operator can place multiple solenoid valve bodies 5 on the transfer slide 3, and then control the movement of the transfer slide 3 to simultaneously send the multiple solenoid valve bodies 5 to the cleaning position for cleaning.

[0036] In this embodiment, a housing 2 is fixedly installed on the outer wall of the fixed frame 1. Multiple openings are provided on the side of the housing 2 near the transfer slide 3. These openings facilitate the smooth entry and exit of the transfer slide 3 and the multiple solenoid valve bodies 5 placed on it. The housing 2 not only provides protection for the internal components of the equipment but also prevents external dust and debris from entering and affecting its normal operation. Furthermore, it ensures that excessive airflow does not overflow during air cleaning, maintaining a clean operating environment and contributing to a cleaner and more aesthetically pleasing overall appearance of the equipment.

[0037] In this embodiment, multiple positioning seats 4 are fixedly installed on the top of the transfer slide 3. These positioning seats 4 cooperate with the solenoid valve body 5 to complete the positioning and fixing of the solenoid valve body 5. The shape and size of the positioning seats 4 are designed according to the shape of the solenoid valve body 5. When the solenoid valve body 5 is placed on the positioning seats 4, it can be accurately positioned in the designated position to avoid movement or shaking during the cleaning process, thereby ensuring the cleaning effect.

[0038] In this embodiment, a photoelectric sensor 7 is provided on one side of the fixed frame 1. The photoelectric sensor 7 is fixedly installed by an external bracket, and its position is precisely adjusted to cooperate with multiple positioning seats 4. When the solenoid valve body 5 is placed on the positioning seat 4, the photoelectric sensor 7 can detect the installation status of the solenoid valve body 5. If the solenoid valve body 5 is installed correctly, the photoelectric sensor 7 will send a corresponding signal to the control system, and the control system will control the subsequent cleaning process according to the signal; if the solenoid valve body 5 is detected to be not installed or not installed correctly, the control system will issue an alarm to remind the operator to check and handle it, thereby ensuring the safe operation of the equipment and the cleaning quality. The photoelectric sensor 7 is the same as that in the announcement number CN222920712U.

[0039] In this embodiment, to achieve horizontal driving of the transfer slide 3, a drive cylinder 10 is provided on one side of the fixed frame 1. One end of the piston rod of the drive cylinder 10 extends into the fixed frame 1 and is fixedly connected to one side of the transfer slide 3. When it is necessary to move the transfer slide 3, the control system sends a signal to the drive cylinder 10, and the piston rod of the drive cylinder 10 extends or retracts, thereby driving the transfer slide 3 to move horizontally on the guide rail. By controlling the action of the drive cylinder 10, the moving distance and position of the transfer slide 3 can be precisely controlled to meet the requirements of different cleaning processes.

[0040] This application can be used in the field of automotive parts processing technology, or in other fields applicable to this application.

[0041] In another embodiment: Reference Figure 1 , 3 Solenoid valve cleaning equipment, which is applied to the field of automotive parts processing technology;

[0042] Furthermore, in this embodiment, a baffle 6 is fixedly installed on one side of the transfer slide 3. The baffle 6 cooperates with multiple openings on one side of the housing 2. When the transfer slide 3 moves into the housing 2, the baffle 6 can block the openings on one side of the housing 2. During the cleaning process, a strong airflow is generated inside the equipment. The baffle 6 can effectively prevent the internal airflow from affecting personnel outside, ensuring the safety of the operators.

[0043] However, as is well known to those skilled in the art, the working principle and wiring method of the drive cylinder 10 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0044] The working principle and usage process of this technical solution are as follows: During use, the operator places the solenoid valve body 5, which has undergone oil circuit pressure and flow testing and has residual oil on its surface and inside, one by one onto the positioning seat 4 on top of the transfer slide 3. The positioning seat 4 ensures that the solenoid valve body 5 is stably positioned and fixed.

[0045] Subsequently, the photoelectric sensor 7, located on one side of the fixed frame 1, detects that the solenoid valve body 5 on the positioning seat 4 is correctly positioned. After confirming the detection signal, the operator can press the external start button.

[0046] Upon receiving the start signal, the drive cylinder 10 on one side of the fixed frame 1 actuates, driving its piston rod to retract. The piston rod drives the transfer slide 3 to move along the guide rail at the bottom of the fixed frame 1 into the equipment, thereby smoothly transporting the transfer slide 3 carrying the solenoid valve body 5 to the preset cleaning position. During this process, the baffle 6 on one side of the transfer slide 3 moves in with the slide and cooperates with the opening on the outer casing 2 to form a barrier, preventing airflow leakage during subsequent cleaning processes from affecting the operating environment.

[0047] When the transfer slide 3 accurately reaches the preset cleaning position, multiple solenoid valve bodies 5 are all located within their respective air blowing hoods 8. The equipment control system then triggers a cleaning command. At this time, multiple air needles 9 open simultaneously. These needles, connected to an external air pump, precisely spray high-pressure gas onto the surface of the solenoid valve body 5 and the internal channels requiring cleaning. The multiple air needles 9, working in conjunction with the corresponding air blowing hoods 8, create effective airflow coverage, ensuring efficient flushing of residual oil from the surface and interior of the solenoid valve body 5.

[0048] The high-pressure gas purging will continue for a predetermined period of time (approximately 20 seconds). This duration is sufficient to ensure that residual oil inside and on the surface of the solenoid valve body 5 is completely purged, achieving the required cleanliness standard.

[0049] After the preset purging time is reached, the control system automatically shuts off the air supply, stopping the air supply to the air needle 9. Then, the piston rod of the drive cylinder 10 extends again, pushing the transfer slide 3 to move in the opposite direction along the guide rail, smoothly transporting the transfer slide 3 carrying the cleaned solenoid valve body 5 back to its initial loading position from inside the equipment. Once the transfer slide 3 has fully reset, the operator can remove the cleaned solenoid valve body 5 from the positioning seat 4. Repeating the above steps allows for continuous and efficient cleaning of subsequent solenoid valve bodies 5.

[0050] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
