Description

Technical Field

[0001] This application relates to the field of solenoid valve assembly technology, and in particular to a solenoid valve assembly and cleaning device. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components in automation systems used to control fluids and adjust the direction, flow rate, speed, and other parameters of the medium. During the assembly process, metal shavings or other impurities are inevitably generated due to the pressing and friction between various components. If these shavings remain inside the solenoid valve, they may cause problems such as valve jamming and poor sealing, seriously affecting the performance and service life of the solenoid valve.

[0003] Currently, the common solutions in the industry include the following two: one is manual cleaning, that is, after assembly, workers use brushes or air guns to manually remove debris. Although this method is simple, it is inefficient and the cleaning effect is unstable. The other is to use a fixed blowing device to blow the surface of the solenoid valve with high-pressure airflow. Although this method improves efficiency, it is difficult to remove stubborn debris, which makes it difficult to improve the assembly quality of the solenoid valve. Summary of the Invention

[0004] To improve the assembly quality of solenoid valves, this application provides a solenoid valve assembly cleaning device.

[0005] The electromagnetic valve assembly and cleaning equipment provided in this application adopts the following technical solution: A solenoid valve assembly and cleaning device includes a frame, an upper cleaning mechanism, a lower cleaning mechanism, and a transfer mechanism. The upper cleaning mechanism is mounted on the frame and is used to clean the upper part of the solenoid valve. The upper cleaning mechanism includes an upper cleaning seat, an upper cleaning cover, a driving component, an air blowing component, a roller brush assembly, a lower cleaning cover, and a suction component. The upper cleaning seat is mounted on the frame and is used to drive the solenoid valve to rotate. The upper cleaning cover is slidably mounted on the frame towards the upper cleaning seat. The driving component is mounted on the frame and is used to drive the upper cleaning cover to slide. The air blowing component is mounted on the upper cleaning cover and is used to blow air into the upper cleaning cover. The roller brush assembly is mounted on the upper cleaning cover and is used to brush away debris from the solenoid valve. The lower cleaning cover is mounted on the frame and covers the upper cleaning seat inside. The suction component is mounted on the lower cleaning cover and is used to suck away debris inside the lower cleaning cover. The lower cleaning mechanism is mounted on the frame and is used to clean the lower part of the solenoid valve. The transfer mechanism is mounted on the frame and is used to transfer the solenoid valve.

[0006] By adopting the above technical solution, the transfer mechanism transfers the assembled solenoid valve to the upper cleaning seat. The driving component drives the upper cleaning cover to move downward, so that the upper cleaning cover covers the solenoid valve. Then, the air blowing component blows high-pressure gas into the upper cleaning cover to blow away the debris on the solenoid valve. At the same time, the upper cleaning seat drives the solenoid valve to rotate. The roller brush assembly brushes away the debris on the solenoid valve during the rotation process, and the suction component sucks away the debris cleaned from the solenoid valve. This can efficiently clean the upper part of the solenoid valve. Then, the driving component moves the upper cleaning cover away from the upper cleaning seat, and the transfer mechanism transfers the solenoid valve on the upper cleaning seat to the lower cleaning mechanism. The lower cleaning mechanism cleans the lower part of the solenoid valve, thereby efficiently and with high quality cleaning the assembled solenoid valve, effectively improving the assembly quality of the solenoid valve.

[0007] Optionally, the roller brush assembly includes a support base, a drive motor, and a brush head. The support base is disposed on the upper cleaning cover, the drive motor is disposed on the support base, and the brush head is disposed on the output shaft of the drive motor and extends into the upper cleaning cover.

[0008] By adopting the above technical solution, the drive motor is started, and the output shaft of the drive motor drives the brush head to rotate, so that the brush head can easily brush away the debris on the solenoid valve.

[0009] Optionally, the support base is slidably disposed on the upper cleaning cover along the axis toward the upper cleaning cover, and the upper cleaning cover is provided with a positioning element for positioning the support base.

[0010] By adopting the above technical solution, the positioning component can be released from the positioning of the support base, which can drive the support base to move towards or away from the axis of the upper cleaning cover. This satisfies the applicability of cleaning solenoid valves of different specifications and sizes. It can also pull the support base away from the axis of the upper cleaning cover to remove the brush head from the upper cleaning cover, and then conveniently maintain the brush head.

[0011] Optionally, the positioning component includes a control plate, a control cylinder, a connecting shaft, a control shaft, and a locking pin. The control plate is hinged to the upper cleaning cover, and both ends of the control plate have slots. The control cylinder is mounted on the upper cleaning cover. The connecting shaft is mounted on the piston rod of the control cylinder and slides through the slot at one end of the control plate. The control shaft slides through the support base and slides through the slot at the other end of the control plate. The locking pin is threaded onto the support base and is used to prevent the control shaft from disengaging from the support base.

[0012] By adopting the above technical solution, the piston rod of the control cylinder extends and retracts, causing the connecting shaft to press against the side wall of the slot on the control plate, thus driving the control plate to rotate. The side wall of the slot at the other end of the control plate presses against the control shaft, causing the control shaft to slide along the support seat. This allows for convenient adjustment of the position of the brush head inside the upper cleaning cover. After the piston rod of the control cylinder stops, the support seat is positioned in the current position. The locking pin can be unscrewed, and the control shaft can be pulled out of the support seat, disconnecting the support seat from the control plate. Then, the support seat can be moved to remove the brush head from the upper cleaning cover.

[0013] Optionally, the upper cleaning seat is provided with a positioning groove for embedding a solenoid valve, and the upper cleaning seat is provided with a plurality of positioning rods for inserting into the solenoid valve.

[0014] By adopting the above technical solution, when the solenoid valve is transferred to the upper cleaning seat, the solenoid valve is embedded in the positioning groove, and the positioning rod is inserted into the solenoid valve, thereby positioning the solenoid valve and improving the stability of the solenoid valve on the upper cleaning seat.

[0015] Optionally, the lower cleaning mechanism includes a lower cleaning seat, a first cleaning cover, a sliding member, a blowing member, a second cleaning cover, a suction member, and a brush assembly. The lower cleaning seat is mounted on the frame and is used to drive the solenoid valve to rotate. The first cleaning cover is slidably mounted on the frame toward the lower cleaning seat. The sliding member is mounted on the frame and is used to drive the first cleaning cover to slide. The blowing member is mounted on the first cleaning cover and is used to blow air into the first cleaning cover. The second cleaning cover is mounted on the frame and covers the lower cleaning seat inside. The suction member is mounted on the second cleaning cover and is used to suck away debris inside the second cleaning cover. The brush assembly is mounted on the frame and is used to brush away debris on the solenoid valve.

[0016] By adopting the above technical solution, the transfer mechanism transfers the solenoid valve on the upper cleaning seat to the lower cleaning seat. The sliding component drives the first cleaning cover to move down and cover the solenoid valve inside. Then, the blowing component blows high-pressure gas into the first cleaning cover. The lower cleaning seat drives the solenoid valve to rotate. The brush assembly brushes away the debris on the solenoid valve, and the suction component sucks away the debris, thus conveniently cleaning the lower end of the solenoid valve.

[0017] Optionally, the brush assembly includes a sliding seat, a sliding cylinder, a brush motor, and a brush body. The sliding seat is slidably mounted on the frame along an axis toward the second cleaning cover. The sliding cylinder is mounted on the frame and is used to drive the sliding seat to slide. The brush motor is mounted on the sliding seat, and the brush body is mounted on the output shaft of the brush motor and extends into the second cleaning cover.

[0018] By adopting the above technical solution, the sliding cylinder drives the sliding seat to slide along the axis that is close to or away from the second cleaning cover. The sliding seat drives the brush body to move, which can adjust the distance between the brush body and the axis of the second cleaning cover, improving the applicability for cleaning solenoid valves of different sizes. Then, the brush motor drives the brush body to rotate, and the brush body can brush away the debris on the solenoid valve.

[0019] Optionally, the transfer mechanism includes a transfer seat, a transfer cylinder, and a clamping assembly. The transfer seat is slidably mounted on the frame along the direction from the upper cleaning mechanism to the lower cleaning mechanism. The transfer cylinder is mounted on the frame and is used to drive the transfer seat to slide. Multiple clamping assemblies are equally spaced on the transfer seat along the sliding direction of the transfer seat. The spacing between adjacent clamping assemblies, the spacing between the tooling at the upper end of the valve sleeve of the closing solenoid valve and the upper cleaning mechanism, the spacing between the upper cleaning mechanism and the tooling at the lower end of the valve sleeve of the closing solenoid valve, and the spacing between the tooling at the lower end of the valve sleeve of the closing solenoid valve and the lower cleaning mechanism are all the same.

[0020] By adopting the above technical solution, the piston rod of the transfer cylinder extends and retracts, causing the transfer seat to move multiple clamping components to the positions of the solenoid valves at the tooling at the upper end of the valve sleeve of the closing solenoid valve, the upper cleaning mechanism, the lower end of the valve sleeve of the closing solenoid valve, and the lower cleaning mechanism. Then, the multiple clamping components clamp the solenoid valves at the tooling at the upper end of the valve sleeve of the closing solenoid valve, the upper cleaning mechanism, the lower end of the valve sleeve of the closing solenoid valve, and the lower cleaning mechanism, respectively. The transfer cylinder drives the transfer seat to move the multiple clamping components, so that the multiple clamping components transfer the solenoid valves to the next position, thereby simultaneously transferring multiple solenoid valves and improving the transfer efficiency of the solenoid valves.

[0021] Optionally, the clamping assembly includes a clamping seat, a lifting cylinder, a rotating cylinder, an extension cylinder, and grippers. The clamping seat is vertically slidably mounted on the transfer seat. The lifting cylinder is mounted on the transfer seat and is used to drive the clamping seat to slide. The rotating cylinder is mounted on the clamping seat. The extension cylinder is mounted on the rotating cylinder. The grippers are mounted on the piston rod of the extension cylinder and are used to clamp the solenoid valve.

[0022] By adopting the above technical solution, after the gripper holds the solenoid valve, the lifting cylinder drives the gripper seat to move upward, and the gripper seat can then lift the electromagnet. During the transfer process, the rotating cylinder drives the extension cylinder and the gripper to rotate, which can adjust the angle of the solenoid valve. The piston rod of the extension cylinder extends, causing the gripper to move the solenoid valve above the corresponding placement position. The lifting cylinder drives the gripper seat to move downward, and the gripper releases the solenoid valve, thus transferring the solenoid valve and adjusting the angle of the solenoid valve during the transfer process.

[0023] Optionally, the frame is provided with a tooling cleaning mechanism for cleaning the tooling of the valve sleeve of the solenoid valve. The tooling cleaning mechanism includes a tooling cover, a brush, a cleaning motor, an air blowing pipe, and an air suction pipe. The tooling cover is mounted on the frame and is used to allow the tooling for closing the valve sleeve of the solenoid valve to extend into it. The brush is rotatably mounted inside the tooling cover. The cleaning motor is mounted on the frame and is used to drive the brush to rotate. The air blowing pipe is connected to the tooling cover and is used to blow air into the tooling cover. The air suction pipe is connected to the tooling cover and is used to suck up the debris inside the tooling cover.

[0024] By adopting the above technical solution, after the tooling for the valve sleeve of the solenoid valve is closed, the tooling for the valve sleeve of the solenoid valve is moved into the tooling cover. The cleaning motor drives the brush to rotate, and the air blowing pipe blows high-pressure gas into the tooling cover, which can clean the debris on the tooling for the valve sleeve of the solenoid valve. Then the suction pipe sucks away the debris in the tooling cover, which facilitates the cleaning of the tooling for the valve sleeve of the solenoid valve, reduces the impact of the debris adhering to the tooling for the valve sleeve of the solenoid valve on the closure of the valve sleeve, and further improves the assembly quality of the solenoid valve.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The air blowing component blows high-pressure gas into the upward cleaning hood to blow away the debris on the solenoid valve. At the same time, the upper cleaning seat drives the solenoid valve to rotate. The roller brush assembly brushes away the debris on the solenoid valve during the rotation process, and the suction component sucks away the debris cleaned from the solenoid valve, thus efficiently cleaning the upper part of the solenoid valve. 2. Drive the support base to move toward or away from the axis of the upper cleaning cover, thereby satisfying the applicability of cleaning solenoid valves of different specifications and sizes. It can also pull the support base away from the axis of the upper cleaning cover to remove the brush head from the upper cleaning cover, and then conveniently maintain the brush head. 3. Clean the debris from the tooling on the valve sleeve of the closing solenoid valve, and then use the suction pipe to suck away the debris from the tooling cover. This facilitates the cleaning of the tooling on the valve sleeve of the closing solenoid valve, reduces the impact of debris adhering to the tooling on the closing of the valve sleeve, and further improves the assembly quality of the solenoid valve.

[0037] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0038] This application discloses a solenoid valve assembly and cleaning device.

[0039] Reference Figure 1 The solenoid valve assembly and cleaning equipment includes a frame 1, an upper cleaning mechanism 2, a lower cleaning mechanism 3, a transfer mechanism 4, and a tooling cleaning mechanism 7.

[0040] Reference Figure 1 , Figure 2 , Figure 3 In this embodiment, the frame 1 is provided with a fixture 8 at the upper end of the valve sleeve of the closing solenoid valve and a fixture 9 at the lower end of the valve sleeve of the closing solenoid valve. Both the fixture 8 at the upper end of the valve sleeve and the fixture 9 at the lower end of the valve sleeve of the closing solenoid valve include a closing seat, a servo motor, a horizontal moving frame, a horizontal moving cylinder, a vertical moving cylinder, and a closing sleeve. The closing seat is rotatably mounted on the frame 1. Both ends of the closing seat are provided with positioning grooves for the solenoid valve to be embedded. The servo motor is mounted on the frame 1 and is used to drive the closing seat to rotate. The horizontal moving frame is slidably mounted on the frame 1. The horizontal moving cylinder is mounted on the frame 1 and is used to drive the horizontal moving frame to slide. Two vertical moving cylinders are installed at intervals on the horizontal moving frame. One closing sleeve is installed on the piston rod of one vertical moving cylinder. The inner diameter of the closing sleeve gradually decreases from the direction closer to the solenoid valve to the direction farther away from the solenoid valve.

[0041] After the solenoid valve is fed onto the closing seat, the servo motor drives the closing seat to rotate, causing the solenoid valve to be closed to rotate to the closing position. The closed solenoid valve rotates out for subsequent transfer mechanism 4 to transfer. Then, the horizontal movement cylinder drives the horizontal movement frame to slide, so that one of the closing sleeves is aligned with the solenoid valve. The vertical movement cylinder drives the closing sleeve to move down. The closing sleeve can close the end of the valve sleeve of the solenoid valve through the squeezing action. When one closing sleeve is closing, the tooling cleaning mechanism 7 can clean the other closing sleeve.

[0042] Reference Figure 1 , Figure 4 The tooling cleaning mechanism 7 is installed on both sides of the frame 1, with one tooling 8 at the upper end of the valve sleeve of the closing solenoid valve and one tooling 9 at the lower end of the valve sleeve of the closing solenoid valve. The tooling cleaning mechanism 7 is used to clean the tooling 8 at the upper end of the valve sleeve of the closing solenoid valve and the tooling 9 at the lower end of the valve sleeve of the closing solenoid valve. The tooling cleaning mechanism 7 includes a tooling cover 71, a brush 72, a cleaning motor 73, an air blowing pipe 74, and an air suction pipe 75. The tooling cover 71 is installed on the frame. On frame 1, brush 72 is rotatably mounted on the inner bottom wall of tool cover 71. Cleaning motor 73 is mounted on frame 1. The output shaft of cleaning motor 73 is coaxially connected to brush body 374. Air blowing pipe 74 is connected and installed on the side wall of tool cover 71. Air blowing pipe 74 is used to supply high-pressure gas into tool cover 71. Air suction pipe 75 is connected and installed on the side wall of tool cover 71 opposite to air blowing pipe 74. Air suction pipe 75 is used to suck away debris inside tool cover 71.

[0043] After the tooling 8 at the upper end of the valve sleeve of the solenoid valve or the tooling 9 at the lower end of the valve sleeve of the solenoid valve closes, the tooling is moved into the tooling cover 71. The cleaning motor 73 is started, and the cleaning motor 73 drives the brush 72 to rotate. The brush 72 brushes away the debris on the tooling. At the same time, the air blowing pipe 74 supplies high-pressure gas into the tooling cover 71. The high-pressure gas blows the debris towards the suction pipe 75. The suction pipe 75 sucks away the debris in the tooling cover 71. This facilitates the cleaning of the tooling 8 at the upper end of the valve sleeve and the tooling 9 at the lower end of the valve sleeve of the solenoid valve, reducing the impact of debris adhering to the tooling 8 at the upper end of the valve sleeve and the tooling 9 at the lower end of the valve sleeve on the closing of the solenoid valve, and improving the assembly quality of the solenoid valve.

[0044] Reference Figure 1 , Figure 5 The upper cleaning mechanism 2 is mounted on the frame 1. The upper cleaning mechanism 2 is used to clean the upper part of the solenoid valve. The upper cleaning mechanism 2 includes an upper cleaning seat 21, an upper cleaning cover 22, a driving component 23, an air blowing component 24, a roller brush assembly 25, a lower cleaning cover 26, and an adsorption component 27. The upper cleaning seat 21 is rotatably mounted on the frame 1 on the center line between the tooling 8 at the upper end of the valve sleeve of the closing solenoid valve and the tooling 9 at the lower end of the valve sleeve of the closing solenoid valve. The upper cleaning seat 21 is used to drive the solenoid valve to rotate. In this embodiment, a servo motor is mounted on the frame 1. The servo motor is connected to the cleaning seat 21 via a belt and pulley, thereby driving the upper cleaning seat 21 to rotate. The upper cleaning seat 21 has a positioning groove for the solenoid valve to be embedded in. At least two positioning rods 6 are installed on the upper cleaning seat 21. The positioning rods 6 are used to pass through the solenoid valve, so that when the solenoid valve is transferred to the upper cleaning seat 21, it can be embedded in the positioning groove and passed through the solenoid valve via the positioning rods 6. The side wall of the positioning groove and the positioning rods 6 together position the solenoid valve, improving the stability of the solenoid valve on the upper cleaning seat 21.

[0045] Reference Figure 5The upper cleaning cover 22 is vertically slidably mounted on the frame 1 towards the upper cleaning seat 21. The driving component 23 is mounted on the frame 1 and is used to drive the upper cleaning cover 22 to slide. The driving component 23 can be a cylinder, electric actuator, or other linear drive. In this embodiment, the driving component 23 is a cylinder, which is vertically mounted on the frame 1. The piston rod of the cylinder is connected to the upper cleaning cover 22. By controlling the extension and retraction of the piston rod of the cylinder 52, the upper cleaning cover 22 can be driven to slide towards or away from the upper cleaning seat 21. The air blowing component 24 is mounted on the upper cleaning cover 22 and is used to blow high-pressure gas into the upper cleaning cover 22. In this embodiment, the air blowing component 24 includes multiple pipes connected to the high-pressure gas source. All multiple pipes are connected and mounted on the upper cleaning cover 22. The high-pressure gas source enters the upper cleaning cover 22 from the multiple pipes and blows the high-pressure gas source towards the solenoid valve, thereby blowing away the debris on the solenoid valve.

[0046] Reference Figure 5 , Figure 6 A set of roller brush assemblies 25 are installed on each side of the upper cleaning cover 22. The roller brush assemblies 25 are used to brush away debris from the solenoid valve. The roller brush assembly 25 includes a support base 251, a drive motor 252, and a brush head 253. The support base 251 is slidably mounted on the upper cleaning cover 22 at an inclination toward the axis of the upper cleaning cover 22. The drive motor 252 is mounted on the support base 251. The brush head 253 is coaxially mounted on the output shaft of the drive motor 252 and extends into the interior of the upper cleaning cover 22. A positioning element 5 is installed on the upper cleaning cover 22. The positioning element 5 is used to position the support base 251. The positioning element 5 includes a control plate 51, a control cylinder 52, a connecting shaft 53, a control shaft 54, and a locking pin 55. The control plate 51 is hinged to the upper cleaning cover 22. The hinge shaft of the control plate 51 is located in the middle. Both ends of the control plate 51 are provided with slotted holes 511. The control cylinder 52 is installed on the upper cleaning cover 22. In this embodiment, the control cylinder 52 is a double-headed cylinder. One connecting shaft 53 is installed on the piston rod at each end of the control cylinder 52. The two connecting shafts 53 are slidably inserted into the slotted holes 511 on the control plate 51 of the roller brush assembly 25 at both ends of the upper cleaning cover 22. The control shaft 54 ​​is slidably inserted into the support base 251 and also slidably inserted into the slotted hole 511 at the other end of the control plate 51. The control shaft 54 ​​is provided with an annular groove. The locking pin 55 is threadedly installed on the support base 251 and inserted into the annular groove on the control shaft 54.

[0047] When dealing with the cleaning needs of solenoid valves of different sizes, the piston rods at both ends of the control cylinder 52 extend synchronously. The piston rods of the control cylinder 52 drive the connecting shaft 53 to press the side wall of the slot 511. This causes the connecting shaft 53 to pull the two control plates 51 to rotate synchronously in opposite directions. The side wall of the slot 511 at the other end of the control plate 51 presses against the control shaft 54. The control shaft 54 ​​then drives the support base 251 to slide, allowing the support base 251 to move the brush head 253 toward or away from the center of the upper cleaning cover 22, facilitating the insertion of the brush head 253 into the upper cleaning cover. The position inside the cleaning cover 22 is adjusted to accommodate cleaning solenoid valves of different sizes. After the piston rod of the control cylinder 52 stops, the connecting shaft 53 and the control shaft 54 ​​no longer slide within the slot 511. The support base 251 can then be positioned in the current position. The locking pin 55 can be unscrewed, and the control shaft 54 ​​can be pulled out of the support base 251, disconnecting the support base 251 from the control plate 51. Then, the support base 251 can be pulled away from the axis of the upper cleaning cover 22 to move the brush head 253 out of the upper cleaning cover 22, and then the brush head 253 can be easily maintained.

[0048] Reference Figure 5 The lower cleaning cover 26 is installed on the frame 1, and the lower cleaning cover 26 covers the upper cleaning seat 21. The adsorption component 27 is installed on the lower cleaning cover 26. The adsorption component 27 is used to suck away the debris in the lower cleaning cover 26. In this embodiment, the adsorption component 27 includes a pipe connected to the suction device. The pipe is connected to the lower cleaning cover 26. The gas in the lower cleaning cover 26 is extracted through the pipe, so that a negative pressure environment is formed in the lower cleaning cover 26. The gas and debris in the upper cleaning cover 22 enter the lower cleaning cover 26 and are then sucked away by the pipe. In addition, a pipe connected to the suction device is also connected to the upper cleaning cover 22. The pipe connected to the suction device and the pipe connected to the high-pressure gas source are arranged opposite to each other, so that the high-pressure gas blows the debris away from the solenoid valve and can be directly sucked away.

[0049] Reference Figure 1 , Figure 7The lower cleaning mechanism 3 is mounted on the frame 1. The lower cleaning mechanism 3 is used to clean the lower part of the solenoid valve. The lower cleaning mechanism 3 includes a lower cleaning seat 31, a first cleaning cover 32, a sliding member 33, a blowing member 34, a second cleaning cover 35, a suction member 36, and a brush assembly 37. The lower cleaning seat 31 is rotatably mounted on the frame 1. The lower cleaning seat 31 and the upper cleaning seat 21 are symmetrically arranged with the tooling 9 at the lower end of the valve sleeve of the closing solenoid valve as the center line. In this embodiment, a servo motor is mounted on the frame 1. The output shaft of the servo motor is connected to the lower cleaning seat 31 via a belt and pulley, thereby driving the lower cleaning seat 31 to rotate. The first cleaning cover 32 is vertically slidably mounted on the frame 1 towards the lower cleaning cover 26. The sliding member 33 is mounted on the frame 1. The sliding member 33 is used to drive the first cleaning cover 32 to slide. In this embodiment, the sliding member 33 is a cylinder, which is mounted on the frame 1, and the piston rod of the cylinder is connected to the first cleaning cover 32. The blowing member 34 is mounted on the first cleaning cover 32 and is used to blow air into the first cleaning cover 32. In this embodiment, the blowing member 34 is a pipe connected to a high-pressure air source, and the pipe is connected to the first cleaning cover 32. The second cleaning cover 35 is mounted on the frame 1 and covers the lower cleaning seat 31 inside. The suction member 36 is mounted on the second cleaning cover 35 and is used to suck away the debris inside the second cleaning cover 35. In this embodiment, the suction member 36 is a pipe connected to a suction device, and the pipe is connected to the second cleaning cover 35.

[0050] Reference Figure 7 , Figure 8 The brush assembly 37 is mounted on the frame 1. The brush assembly 37 is used to brush away debris on the solenoid valve. The brush assembly 37 includes a sliding seat 371, a sliding cylinder 372, a brush motor 373, and a brush body 374. The sliding seat 371 is slidably mounted on the frame 1 with an inclination toward the axis of the second cleaning cover 35. The sliding cylinder 372 is mounted on the frame 1. The piston rod of the sliding cylinder 372 is connected to the sliding seat 371. The brush motor 373 is mounted on the sliding seat 371. The brush body 374 is coaxially mounted on the output shaft of the brush motor 373 and extends into the interior of the second cleaning cover 35.

[0051] After the lower end of the solenoid valve sleeve is closed, it is transferred to the lower cleaning seat 31. The sliding member 33 drives the first cleaning cover 32 to move down, and the first cleaning cover 32 is fastened onto the second cleaning cover 35, thus covering the solenoid valve inside. The blowing member 34 blows high-pressure gas into the first cleaning cover 32. The high-pressure gas blows the debris on the solenoid valve towards the second cleaning cover 35. At the same time, the lower cleaning seat 31 drives the solenoid valve to rotate, and the brush motor 373 drives the brush body 374 to rotate. The brush body 374 brushes away the debris on the solenoid valve during the rotation process by rotating. The suction member 36 then sucks away the debris, thus... The device allows for quick cleaning of the lower end of the solenoid valve and can also drive the sliding seat 371 to slide via the sliding cylinder 372. This allows the sliding seat 371 to move the brush body 374 closer to or further away from the axis of the second cleaning cover 35, adjusting the position of the brush body 374 within the second cleaning cover 35. This makes the brush body 374 suitable for solenoid valves of different sizes, improving its applicability for cleaning solenoid valves of different sizes. Furthermore, the sliding seat 371 can be driven by the sliding cylinder 372 to move the brush body 374 out of the second cleaning cover 35, facilitating convenient maintenance of the brush body 374.

[0052] Reference Figure 1 , Figure 9 , Figure 10 The transfer mechanism 4 is mounted on the frame 1. The transfer mechanism 4 is used to transfer the solenoid valve. The transfer mechanism 4 includes a transfer seat 41, a transfer cylinder 42, and clamping components 43. The transfer seat 41 is slidably mounted on the frame 1 along the direction from the upper cleaning mechanism 2 towards the lower cleaning mechanism 3. The transfer cylinder 42 is mounted on the frame 1 and is used to drive the transfer seat 41 to slide. Four clamping components 43 are evenly spaced on the transfer seat 41 along the sliding direction of the transfer seat 41. The spacing between the fixture 8 at the upper end of the valve sleeve of the closing solenoid valve and the upper cleaning mechanism 2 in the sliding direction of the transfer seat 41, the spacing between the fixture 9 at the lower end of the valve sleeve of the closing solenoid valve and the lower cleaning mechanism 3 in the sliding direction of the transfer seat 41 are as follows: The upward spacing is the same as the spacing between adjacent clamping components 43. The clamping component 43 includes a clamping seat 431, a lifting cylinder 432, a rotating cylinder 433, an extension cylinder 434, and a gripper 435. The clamping seat 431 is vertically slidably mounted on the transfer seat 41. The lifting cylinder 432 is vertically mounted on the transfer seat 41. The piston rod of the lifting cylinder 432 is connected to the clamping seat 431. The rotating cylinder 433 is mounted on the clamping seat 431. The extension cylinder 434 is mounted on the rotating cylinder 433. The gripper 435 is mounted on the piston rod of the extension cylinder 434. The gripper 435 is used to clamp the solenoid valve. In this embodiment, the gripper 435 includes a double-headed cylinder and a clamping plate. The double-headed cylinder is mounted on the piston rod of the extension cylinder 434. One clamping plate is mounted on the piston rod at each end of the double-headed cylinder.

[0053] The piston rod of the transfer cylinder 42 extends and retracts, causing the transfer seat 41 to move the four grippers 435 to the solenoid valves respectively aligned with the tooling 8 at the upper end of the valve sleeve of the closing solenoid valve, the solenoid valve on the upper cleaning seat 21, the solenoid valve at the tooling 9 at the lower end of the valve sleeve of the closing solenoid valve, and the solenoid valve on the lower cleaning seat 31. Then, the piston rods of the lifting cylinder 432 and the extension cylinder 434 extend and retract, causing the two clamping plates of the grippers 435 to move to both sides of the solenoid valve, and the grippers 435 to clamp the solenoid valve. Then, the piston rods of the lifting cylinder 432 and the extension cylinder 434 extend and retract again, lifting the solenoid valve and bringing it close to the transfer seat 41. Simultaneously, the four grippers 435 clamp the solenoid valves at the tooling 8 at the upper end of the valve sleeve of the closing solenoid valve, the solenoid valve at the upper cleaning mechanism 2, and the solenoid valve at the lower cleaning seat 31. The solenoid valves at the lower tooling 9 and the lower cleaning mechanism 3 are connected by a transfer cylinder 42, which drives the transfer seat 41 to slide. The transfer seat 41 moves the gripper 435, which in turn moves the solenoid valve to the next processing or cleaning position. During the transfer process, the rotary cylinder 433 can also drive the extension cylinder 434 and the gripper 435 to rotate, thereby driving the solenoid valve to flip and adjust its angle. Then, the piston rod of the extension cylinder 434 extends, causing the gripper 435 to move the solenoid valve to the position above the placement position. The lifting cylinder 432 drives the clamping seat 431 to move the gripper 435 down, and the gripper 435 releases the solenoid valve, thus transferring the solenoid valve to the next processing or cleaning position simultaneously. This allows for the simultaneous transfer of multiple solenoid valves, improving the transfer efficiency of the solenoid valves.

[0054] The implementation principle of the solenoid valve assembly and cleaning equipment in this application embodiment is as follows: After the tooling 8 at the upper end of the valve sleeve of the solenoid valve closes the upper end of the solenoid valve, the transfer mechanism 4 transfers the solenoid valve to the upper cleaning seat 21. The driving component 23 drives the upper cleaning cover 22 to fasten onto the lower cleaning cover 26, covering the solenoid valve inside. The air blowing component 24 blows high-pressure gas into the upper cleaning cover 22, causing the upper cleaning cover 22 to rotate. The drive motor 252 drives the brush head 253 to rotate, so that the brush head 253 can clean the electric current generated during the rotation. The debris on the solenoid valve is brushed off, and the adsorption component 27 sucks away the debris cleaned from the solenoid valve, thus efficiently cleaning the upper end of the solenoid valve's closing section. Then, the transfer mechanism 4 transfers the solenoid valve to the tooling 9 at the lower end of the valve sleeve of the closing solenoid valve. After the lower end of the solenoid valve is closed, the lower cleaning mechanism 3 cleans the lower end of the closing section of the solenoid valve, thus efficiently and with high quality cleaning the assembled solenoid valve. At the same time, the tooling cleaning mechanism 7 also cleans the tooling of the closing solenoid valve, effectively improving the assembly quality of the solenoid valve.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
