Description

Technical Field

[0002] The mechanical diaphragm metering pump is a fluid conveying machine. Its plunger and diaphragm are directly connected by screws. When working, the plunger reciprocates to drive the diaphragm to repeatedly agitate, and the one-way valve on the pump head is opened and closed to complete the suction and discharge purpose, so as to achieve the function of conveying liquid. During the processing of the metering pump, each component needs to be cleaned before assembly to avoid loose assembly or poor fit due to impurities; During the processing of mechanical diaphragm metering pumps, the diaphragm of the metering pump is easily damaged by the impact of high-pressure water flow, so the metal parts flushing and diaphragm cleaning need to be carried out separately. The diaphragm cleaning is usually carried out at the same station as the pump body assembly. After completing the assembly of other parts, the workers at this station need to use a soft brush to clean the metering pump diaphragm in clean water, and then connect the metering pump diaphragm to the metering pump plunger with screws, resulting in low work efficiency; At the same time, during the processing, the existing inspection process only separately inspects the various properties of the diaphragm and the screws, and lacks the inspection of the connection strength between the diaphragm and the screws. This may cause defective products to be installed in the metering pump body, resulting in the metering pump diaphragm and the screws cannot work normally due to water leakage. Therefore, a cleaning device for metering pump processing is proposed to solve the above problem. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Example, see Figures 1 to 7A cleaning device for metering pump processing, comprising a metering pump body 1, a mechanical arm 2, a metering pump diaphragm 3, a screw 4 and a gasket 5, an actuator assembly is arranged at the output end of the mechanical arm 2, and a cleaning assembly, a pump body conveyor belt 6 and a plurality of diaphragm conveyor belts 7 are arranged on three sides of the mechanical arm 2 in a clockwise direction; The actuator assembly includes a rotating rod 8, the outer wall of the rotating rod 8 is rotatably connected to a first conductive slip ring 9, the top end of the first conductive slip ring 9 is fixedly connected to the mechanical arm 2, one end of the rotating rod 8 is fixedly connected to a coupling 10 for docking the mechanical arm 2, and the other end of the rotating rod 8 is fixedly connected to a cutter head 11 for installing the screw 4; The cleaning assembly is arranged opposite to the diaphragm conveyor belt 7, the metering pump diaphragm 3, the screw 4 and the gasket 5 are located on the surface of the diaphragm conveyor belt 7, the metering pump body 1 is located on the surface of the pump body conveyor belt 6, and a connection strength test assembly is arranged on the top of the cleaning assembly; The cleaning assembly includes a cleaning table 12, a partition 13 is provided at one end of the surface of the cleaning table 12 away from the robot arm 2, a rotating platform 14 is provided at the center inside the cleaning table 12, the rotating platform 14 is rotatably connected to a rotating shaft 15, a second conductive slip ring 16 is rotatably connected to the outer wall of the rotating shaft 15, the bottom of the second conductive slip ring 16 is fixedly connected to the top of the rotating platform 14, a multi-station turntable 17 is provided at the top of the rotating shaft 15, a test cylinder 18 is fixedly connected to the center of the surface of the multi-station turntable 17, and a plurality of cleaning disks 19 are provided on the surface of the multi-station turntable 17 around the test cylinder 18; The connection strength test assembly includes a bracket 20 , the bottom of the bracket 20 is fixedly connected to the top of the partition 13 , the top of the bracket 20 is fixedly connected to an electric push cylinder 21 , and the output end of the electric push cylinder 21 passes through the bracket 20 and is fixedly connected to a test cover plate 22 .

[0020] It should be noted that the metering pump body 1 and the mechanical arm 2 are both existing technologies and will not be described in detail.

[0021] It is worth noting that: two diaphragm conveyor belts 7 are provided and the output directions are opposite, and the conveying direction toward the robot arm 2 is the positive direction.

[0022] Furthermore, a cushion block 23 is fixedly connected to the surface of the diaphragm conveyor belt 7, a fixing sleeve 24 for connecting the screw 4 is fixedly connected to the center of the cushion block 23, and a thread matching the screw 4 is provided on the top of the fixing sleeve 24 to ensure the consistency of the "I" groove in the screw 4 during the conveying process, so as to facilitate the grabbing of the actuator assembly; Furthermore, an electromagnet 25 is fixedly installed inside the rotating rod 8, and the electromagnet 25 is electrically connected to the first conductive slip ring 9. During the rotation of the rotating rod 8, the electromagnet 25 can be powered by the first conductive slip ring 9. The bottom end of the rotating rod 8 is fixedly connected to a limiting hoop 26 matching the screw 4, which is used to improve the stability of the screw 4 during the movement. A further advantage of adopting the above is that when the mechanical arm 2 drives the cutter head 11 to enter the "I"-shaped groove, the electromagnet 25 is energized and the screw 4 is attracted by magnetic force to make it close to the limit hoop 26, and the gasket 5 is attracted by magnetic force at the same time, so that the gasket 5 squeezes the metering pump diaphragm 3 from below, and the metering pump diaphragm 3 is fixed by the pressure of the screw 4 and the gasket 5. The mechanical arm 2 drives the rotating rod 8 and the cutter head 11 to rotate through the coupling 10, and the metering pump diaphragm 3, the screw 4 and the gasket 5 are assembled through the cutter head 11, thereby realizing the function of transporting and assembling the metering pump diaphragm 3; Furthermore, a cleaning water injection pipe 27 for providing cleaning water is fixedly connected to a surface of the cleaning table 12 near a corner of the test plate, and an output end of the cleaning water injection pipe 27 is aligned with the test plate. A cleaning water discharge pipe 28 is fixedly connected to the inner wall of the cleaning table 12; Furthermore, a first fixing column 31 matching the screw 4 is fixedly connected to the center of the bottom of the test cylinder 18, a limiting ring 29 matching the test cover plate 22 is fixedly connected to the inner wall of the test cylinder 18, and an exhaust hole 30 is opened on the side wall of the test cylinder 18 below the limiting ring 29, so that the air pressure at the bottom of the test cylinder 18 is consistent with the atmospheric pressure; Furthermore, a water guiding slope 32 for guiding water flow is fixedly connected to the bottom of the cleaning plate 19, a second fixing column 33 matching the screw 4 is fixedly connected to the center of the surface of the water guiding slope 32, an ultrasonic generator 34 is fixedly connected to the center of the water guiding slope 32, a drain port is provided at the bottom end of the water guiding slope 32, a solenoid valve 35 is fixedly connected to the bottom of the drain port, the ultrasonic generator 34 and the solenoid valve 35 are electrically connected to the second conductive slip ring 16, and the ultrasonic generator 34 and the solenoid valve 35 of each station are powered by the second conductive slip ring 16 during the rotation of the multi-station turntable 17; A further advantage of adopting the above method is that after the robot arm 2 moves and installs the metering pump diaphragm 3, screws 4 and gasket 5 on the top of the second fixed column 33, the upper and lower surfaces of the metering pump diaphragm 3 are exposed and can fully contact clean water. Ultrasonic waves are generated by the ultrasonic generator 34, and the cavitation effect is used to clean the tiny pores on the surface of the metering pump diaphragm 3. After cleaning, the solenoid valve 35 is opened to allow the sewage to flow along the water guide slope 32 into the solenoid valve 35 and be discharged into the cleaning water discharge pipe 28, and finally discharged into the sewer through the cleaning water discharge pipe 28, thereby realizing the function of cleaning the metering pump diaphragm 3.

[0023] Furthermore, the top of the test cover plate 22 is fixedly connected with an air circuit interface 36, which is connected to an air pump in the prior art to provide a test air flow, and the inside of the test cover plate 22 is fixedly installed with an air pressure sensor 37 for detecting the connection strength of the metering pump diaphragm 3, and the air pressure inside the test cover plate 22 is measured by the air pressure sensor 37 to judge and detect the connection strength between the metering pump diaphragm 3 and the screw 4; A further advantage of adopting the above method is that when the electric push cylinder 21 drives the test cover 22 to descend into the test tube 18, the metering pump diaphragm 3 is squeezed by the test cover 22 and the limit ring 29 to seal the test cover 22 and the metering pump diaphragm 3, and air is supplied to the inside of the test cover 22 through the air pump. After the air supply is completed, the air pressure value is collected by the air pressure sensor 37. If the value is lower than the standard value, it indicates that the connection strength between the metering pump diaphragm 3 and the screw 4 is poor, thereby realizing the function of connection strength detection.

[0024] When the present invention is used, the metering pump diaphragm 3, the screw 4 and the gasket 5 are transported to the working area of ​​the mechanical arm 2 through the diaphragm conveyor belt 7 arranged in the forward direction. In this process, the "I" groove in the screw 4 is kept consistent during the transportation process through the fixing sleeve 24; When grasping, the robot arm 2 carries the actuator assembly and moves to the top of the fixed sleeve 24, and descends until the cutter head 11 enters the "I" groove in the screw 4. At this time, the electromagnet 25 is energized and the screw 4 is attracted by magnetic force to make it close to the limit hoop 26. At the same time, the gasket 5 is attracted by magnetic force to squeeze the metering pump diaphragm 3 from the bottom, and the metering pump diaphragm 3 is fixed by the pressure of the metering pump diaphragm 3. Then the robot arm 2 slowly rises and drives the rotating rod 8 to rotate through the coupling 10. The cutter head 11 is driven by the rotating rod 8 to rotate and remove the screw 4 from the fixed sleeve 24. After the disassembly is completed, the diaphragm conveyor belt 7 set in the forward direction is activated to convey the metering pump diaphragm 3, screws 4 and gaskets 5 to be assembled to the working area of ​​the robot arm 2. This process will not be repeated; During the operation, the robot arm 2 grabs the metering pump diaphragm 3, screws 4 and gasket 5 from the fixing sleeve 24, and moves to the top of the first fixing column 31. The robot arm 2 slowly descends and drives the rotating rod 8 to rotate through the coupling 10. The rotating rod 8 drives the cutter head 11 to rotate so that the screw 4 is threadedly connected with the first fixing column 31, and the inspection preparation is completed. Then the robot arm 2 moves to the top of the cleaning tray 19 close to itself. If the metering pump diaphragm 3 is not placed in the cleaning tray 19 at this time, the robot arm 2 stands by. If the metering pump diaphragm 3 is placed in the cleaning tray 19 at this time, the robot arm 2 grabs the metering pump diaphragm 3, screws 4 and gasket 5 from the cleaning tray 19 and moves to align with the plunger in the metering pump body 1, and then assembles through the lateral movement of the robot arm 2 and the rotation of the cutter head 11. After the assembly is completed, the pump body conveyor belt 6 is actuated to move the next metering pump body 1 to be assembled to the working area of ​​the robot arm 2. At the same time, the electric push cylinder 21 drives the test cover plate 22 to descend. When the electric push cylinder 21 drives the test cover plate 22 to descend into the test tube 18, the metering pump diaphragm 3 is squeezed by the test cover plate 22 and the limit ring 29 to seal the test cover plate 22 and the metering pump diaphragm 3. The air pump is used to supply air to the inside of the test cover plate 22. After the air supply is completed, the air pressure value is collected by the air pressure sensor 37. If the value is higher than the standard value, it indicates that the connection strength is qualified. At this time, the metering pump diaphragm 3, screws 4 and gaskets 5 are self-tested by the mechanical arm 2. The test tube 18 is grabbed and moved to the cleaning disk 19 close to itself and installed in the second fixed column 33. If the value is lower than the standard value, it indicates that the connection strength between the metering pump diaphragm 3 and the screw 4 is poor. At this time, the metering pump diaphragm 3, screw 4 and gasket 5 are grabbed from the test tube 18 by the mechanical arm 2, moved to the reversely arranged diaphragm conveyor belt 7, and the screw 4 is installed in the fixed sleeve 24, and output by the reversely arranged diaphragm conveyor belt 7. A set of actions is completed, and the function of testing the connection strength and screening defective products is realized; When the cleaning tray 19 located in the working area of ​​the robot arm 2 is empty, the cleaning component does not act. When the metering pump diaphragm 3, the screws 4 and the gaskets 5 are fixed to the inside of the second fixing column 33 in the cleaning tray 19 by the robot arm 2, the cleaning component performs the first action, and the rotating shaft 15 is driven by the rotating platform 14 to drive the multi-station turntable 17 to rotate 60°, so that the cleaning tray 19 of this station moves to the bottom of the cleaning water injection pipe 27, and clean water is injected into the cleaning tray 19 by the cleaning water injection pipe 27 to support ultrasonic cleaning. At this time, the cleaning tray 19 of the next station enters the working area of ​​the robot arm 2; When the cleaning component performs the second to fourth actions, the cleaning plate 19 of this station is located below the partition 13. At this time, the ultrasonic generator 34 is turned on for two minutes through the program and generates ultrasonic waves. Under the combined action of ultrasonic waves and clean water, the bubbles generated by the cavitation effect penetrate into the tiny pores on the surface of the metering pump diaphragm 3 for cleaning, thereby removing the powder precipitated from the metering pump diaphragm 3 due to the residues of vulcanizing agent, zinc oxide and antioxidant during the production process, thereby achieving the cleaning function; When the cleaning assembly performs the fifth action, the cleaning plate 19 of this station is located above the cleaning water discharge pipe 28 and the cleaning is completed. At this time, the solenoid valve 35 is opened to allow the sewage to flow along the water guide slope 32 to the solenoid valve 35 for discharge. The discharged sewage enters the cleaning water discharge pipe 28 under the action of gravity and is finally discharged into the sewer through the cleaning water discharge pipe 28. When the cleaning component performs the sixth action, the cleaning tray 19 of this station carries the cleaned metering pump diaphragm 3 back to the working area of ​​the robot arm 2, and is installed to the plunger in the metering pump body 1 by the coordinated use of the robot arm 2 and the actuator assembly, thereby achieving the effect of cleaning multiple metering pump diaphragms 3 at the same time and improving work efficiency.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
