Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a NdFeB automatic, efficient and environmentally friendly cleaning equipment and method. Background Art

[0002] NdFeB is one of the strongest permanent magnet materials currently available. It is widely used in various fields due to its excellent high remanence, high coercivity and high energy product characteristics. During the production process of NdFeB, pollutants such as oil, dust, and metal debris may adhere to its surface. These pollutants not only affect the bonding performance and coating quality of NdFeB, but may also have a negative impact on its mechanical assembly accuracy and the final application effect. Therefore, it is very necessary to clean NdFeB before and after production and use.

[0003] At present, the cleaning of NdFeB is usually completed by a frame-type cleaning machine. During the cleaning process, the NdFeB is manually placed into the mesh frame of the frame-type cleaning machine, and then the mesh frame containing the NdFeB is lowered into the cleaning tank by the lifting arm for ultrasonic cleaning. After the cleaning is completed, the lifting arm lifts the mesh frame and moves it to the rinsing tank for rinsing. After the rinsing is completed, the mesh frame is lifted again, and finally the cleaned NdFeB is manually removed from the mesh frame. This cleaning process requires repeated use of the lifting arm to lift and transfer the NdFeB up and down, which is not only time-consuming, but also cannot achieve continuous cleaning operations, resulting in low efficiency. In addition, the manual unloading method is inefficient, increases labor intensity, and further reduces the overall cleaning efficiency. Summary of the invention

See Figure 10-11The guide rail 1 5 is composed of two low-level sections 51, two downhill sections 52, two uphill sections 53, a high-level section 54, two arc sections 55 and a flat section 56. The flat section 56 is located in the loading and unloading port 31. The two arc sections 55 are respectively located on the left and right sides of the flat section 56.

On the right side of the two low level sections 51, the high level section 54 is located between the left uphill section 53 and the right downhill section 52. A through groove 57 for the T-shaped lifting rod 6 to slide is opened along its circumference at the bottom of the guide rail 5. A guide plate 10 is embedded on the right rear side of the bottom of the T-shaped lifting rod annular cover 3. The guide plate 10 is installed with a tilted installation with a high front and a low rear. An inverted T-shaped push plate 11 located on the upper side of the guide plate 10 is connected to the top of the inner side of the annular cover 3. The left and right sides of the connecting ring 81 and the annular filter plate 82 are both opened with the inverted T The notch 84 of the inner and outer electric annular slide rails 4 is matched with the push block 9 located just above the guide plate 10. The front and rear push blocks 9 are both provided with an inclined surface 91 on the side close to each other. The wedge block 87 moves to contact the push block 9 on the same side and is squeezed by the inclined surface 91 on the push block 9 back into the linear slide rail 85 and disengaged from the upper support block 88 to release the lock of the annular filter 83. The annular filter 83 moves down accordingly. After the annular filter 83 moves down, it is located in the inverted T-shaped On the lower side of the push plate 11, a gap is left between the inverted T-shaped push plate 11 and the material guide plate 10 for the annular filter 83 to pass through, so that when the annular filter 83 drives the rinsed NdFeB thereon to move to the upper side of the material guide plate 10, the NdFeB on the annular filter 83 is pushed out onto the material guide plate 10 by the inverted T-shaped push plate 11, and the material guide plate 10 guides the NdFeB on it backwards. A ramp plate 12 is embedded at the bottom of the annular cover 3 and is located on the left side of the material guide plate 10, which is used to push the annular filter 83 to move up and reset.

[0038] First, connect the two injection tubes 27 to the infusion equipment to inject clean water into the rinsing chamber 23 and the cleaning chamber 24, then pour the cleaning agent into the cleaning chamber 24 to mix with the clean water, and make sure that the water level in the cleaning chamber 24 and the rinsing chamber 23 is always flush with the water level line 26. Then, put the NdFeB to be cleaned into the screen frame 8 through the access port 31, and then control the two electric annular slide rails 4 to open synchronously to drive the T-shaped lifting rod 6 to drive the screen frame 8 to move along the electric annular slide rail 4. When the T-shaped lifting rod 6 moves rightward to the left downslope section 52 on the guide rail 1-5, the T-shaped lifting rod 6 moves downward along the left downslope section 52 on the guide rail 1-5 into the cleaning chamber 24, so that the screen frame 8 drives the NdFeB therein to move down into the cleaning chamber 24 for cleaning. At the same time, the ultrasonic transducer 25 is controlled to work and generate ultrasonic waves, which are transmitted in the liquid to achieve ultrasonic cleaning of the NdFeB. The principle of ultrasonic cleaning is the existing technology and will not be repeated here. In the process of the T-shaped lifting rod 6 moving to the right along the low level section 51 on the guide rail 5, the screen frame 8 and the NdFeB are always kept below the water level line 26, thereby ensuring that the NdFeB is fully cleaned. When the T-shaped lifting rod 6 moves to the right to the left upward slope section 53 area on the guide rail 5, the T-shaped lifting rod 6 moves upward along the left upward slope section 53 on the guide rail 5, so that the screen frame 8 moves upward out of the cleaning chamber 24; when the T-shaped lifting rod 6 moves to the right to the right downward slope section 52 area on the guide rail 5, the T-shaped lifting rod 6 moves downward along the right downward slope section 52 on the guide rail 5 into the rinsing chamber 23, so that the screen frame 8 drives the neodymium iron boron therein to move downward into the rinsing chamber 23 for rinsing; when the T-shaped lifting rod 6 moves to the right to the right upward slope section 53 on the guide rail 5, the T-shaped lifting rod 6 moves upward along the right upward slope section 53 on the guide rail 5, so that the screen frame 8 moves upward out of the rinsing chamber 23. In this way, the electric annular slide rail 4 can drive the T-shaped lifting rod 6 to drive the screen frame 8 to move along the annular cover 3. Through the cooperation of the guide rail 5 and the T-shaped lifting rod 6, the screen frame 8 can be driven to drive the neodymium iron boron inside it to enter and exit the cleaning chamber 24 and the rinsing chamber 23 in sequence during the movement of the screen frame 8 along the annular cover 3, thereby continuously performing the cleaning operation of the neodymium iron boron, which significantly improves the cleaning efficiency. When the wedge block 87 on the screen frame 8 approaches and contacts the push block 9 on the same side, the wedge block 87 continues to move and is squeezed by the inclined surface 91 on the push block 9 to retract into the linear slide rail 1 85 and disengage from the upper support block 88, compressing the spring 2 89, thereby releasing the lock on the annular filter 83, and the annular filter 83 moves downward and is located on the lower side of the inverted T-shaped push plate 11, so that the annular filter 83 drives the rinsed NdFeB thereon to move to the upper side of the guide plate 10, and the NdFeB on the annular filter 83 is pushed onto the guide plate 10 by the inverted T-shaped push plate 11, and the guide plate 10 guides the NdFeB on it backwards to realize automatic unloading, so that there is no need for manual unloading, which reduces manual intervention, reduces labor intensity, and improves overall cleaning efficiency.When the wedge block 87 follows the lifting block 86 to move downward and pass over the upper support block 88, under the restoring action of the spring 2 89, the wedge block 87 is pushed to extend outside the linear slide rail 1 85 and contact the lower support block 88, so that the wedge block 87 is supported by the lower support block 88 to prevent the annular filter screen 83 from directly separating from the annular filter plate 82. When the annular filter 83 passes over the inverted T-shaped push plate 11 and contacts the slope on the ramp plate 12, the annular filter 83 continues to move and is pushed upward by the slope on the ramp plate 12, so that the lifting block 86 drives the wedge block 87 to move up and reset. When the wedge block 87 moves up to contact the upper side support block 88, the wedge surface on the top of the wedge block 87 is squeezed by the upper side support block 88, so that the wedge block 87 retracts into the linear slide rail 1 85 and compresses the spring 2 89. When the wedge block 87 moves up and passes over the upper side support block 88, under the reset action of the spring 2 89, the wedge block 87 is pushed to extend out of the linear slide rail 1 85 and contact the upper side support block 88, thereby locking the annular filter 83 again.

[0039] See also Figure 10-11 , openings 130 are provided at the two low level sections 51 on the front and rear guide rails 1 5, and the left and right openings 130 are respectively located above the rinsing chamber 23 and the cleaning chamber 24, and a guide rail 2 132 is slidably provided in the opening 130, and the T-shaped lifting rod 6 on the inner electric annular slide rail 4 can move into the guide rail 2 132 on the rear side, and the T-shaped lifting rod 6 on the outer electric annular slide rail 4 can move into the guide rail 2 132 on the front side, and the guide rail 2 132 is used to guide the T-shaped lifting rod 6 to rise and fall, so that the screen frame 8 can rise and fall in the cleaning chamber 24 and the rinsing chamber 23, see Fig.11 The guide rail 132 is composed of two upper slope sections 1321 and two lower slope sections 1322. The guide rail 132 is arranged from left to right as an upper slope section 1321, a lower slope section 1322, an upper slope section 1321, and a lower slope section 1322. The low level section 51 on the guide rail 1 5 is symmetrically connected to two linear slide rails 133 with the guide rail 132 as the symmetry center. The guide rail 132 is slidably connected in the linear slide rail 133. The linear slide rail 133 is used to guide the guide rail 132 to move forward and backward. The sides of the linear slide rails 133 on the front and rear sides that are close to each other are hinged with a connecting rod 135. A connecting rod 134 is hinged between the front and rear connecting rods 135. The connecting rod 134 is connected to a rotating shaft 131, and the rotating shaft 131 is rotatably connected to the inner top of the annular cover 3 through a bearing.

[0040] Initially, guide rail two 132 is located outside guide rail one 5. If the NdFeB to be cleaned is a non-standard part with a complex structure or a hole, the rotating shaft 131 is manually rotated, and the rotation of the rotating shaft 131 drives the connecting rod one 134 to rotate. The rotation of the connecting rod one 134 pushes the front and rear guide rails two 132 away from each other through the connecting rod two 135, so that the front and rear guide rails two 132 respectively enter the low horizontal sections 51 on the two guide rails one 5. When the T-shaped lifting rod 6 moves rightward to the left upper slope section 1321 area on the second guide rail 132, the T-shaped lifting rod 6 moves upward along the left upper slope section 1321 on the second guide rail 132, and when the T-shaped lifting rod 6 moves rightward to the left lower slope section 1322 area on the second guide rail 132, the T-shaped lifting rod 6 moves downward along the left lower slope section 1322 on the second guide rail 132, so that the net frame 8 drives the NdFeB inside it to rise and fall, and the NdFeB always remains below the water level 26 during the rising and falling process. Since the second guide rail 132 is composed of two upper slope sections 1321 and two lower slope sections 1322, the NdFeB can be lifted up and down twice when cleaning in the cleaning chamber 24 and when rinsing in the rinsing chamber 23. During the ultrasonic cleaning and rinsing process, tiny bubbles will be formed on the surface of the NdFeB. If these bubbles stay in the same position for a long time, they may affect the cleaning effect. By lifting the complex structure or non-standard parts with holes up and down, these bubbles can be broken and redistributed, thereby improving the cavitation effect to improve the cleaning effect and ensure that the complex structure or non-standard parts with holes can be cleaned. When the complex structure or non-standard parts with holes are lifted up and down, the impact of water can help remove the dirt in the hole and other difficult-to-reach areas, ensuring that the complex structure or non-standard parts with holes can be thoroughly cleaned. If you want to clean square or round non-porous standard parts of NdFeB, reverse the shaft 131 so that the front and rear two guide rails 132 are removed from the low level section 51 on the guide rail 1 5.

[0041] See also Figure 3 A nozzle 141 for spraying upward is installed at the bottom of the inner side of the rinsing chamber 23 and the cleaning chamber 24. The shape of the nozzle 141 is S-shaped. An air compressor 142 is installed at the bottom of the inner side of the water tank 2. The air compressor 142 is connected to the nozzle 141.

[0042] The air compressor 142 is controlled to work to deliver gas to the nozzle 141, and the nozzle 141 then sprays the gas upward into the water to generate tiny bubbles, further intensifying the cavitation effect, thereby improving the cleaning effect on the NdFeB.

[0043] See also Figure 3A second nozzle 151 for spraying air toward the left is embedded on the upper side of the middle of the wavy partition 22. The second nozzle 151 is located on the right side of the cleaning chamber 24 and is connected to the air compressor 142. A solenoid valve is installed on the second nozzle 151. A liquid outlet 28 is opened on the upper left side of the wavy partition 22. A collecting frame 152 is connected to the left side of the water tank 2. The collecting frame 152 is located on the lower left side of the liquid outlet 28. A drain pipe 153 is connected to the front side of the bottom of the collecting frame 152. The drain pipe 153 extends out of the water tank 2. The inner bottom of the collecting frame 152 is designed to be low in the front and high in the back, so that the oil can flow naturally to the drain pipe 153 to reduce residue.

[0044] Oil and impurities with a density less than that of water will float on the water surface in the cleaning chamber 24. After the cleaning work has been carried out for a period of time, the solenoid valve on the second nozzle 151 is controlled to open, so that the air compressor 142 delivers gas to the second nozzle 151. The second nozzle 151 then sprays the gas to the left to blow the oil and impurities floating on the water surface in the cleaning chamber 24 to the left through the liquid outlet 28 to the outside of the cleaning chamber 24. The oil and impurities then fall into the collection frame 152 and are then discharged to the outside through the drain pipe 153, thereby further improving the cleaning effect on the NdFeB. By removing the oil and impurities floating on the water surface, the number of water changes is reduced, thereby saving water resources, reducing water waste, and achieving the purpose of environmental protection. After the oil and impurities floating on the water surface are blown out, the solenoid valve on the second nozzle 151 is controlled to be closed to achieve intermittent cleaning of the oil and impurities floating on the water surface, and when the net frame 8 drives the NdFeB inside it to completely enter below the water level line 26, the cleaning operation of the floating oil and impurities is performed to avoid blowing the oil and impurities back onto the NdFeB.

[0045] See also Figure 2-Figure 3 An electric push rod 161 located on the upper side of the collecting frame 152 is installed on the left front side of the bottom of the annular cover 3, and a plugging plate 162 for blocking the liquid outlet 28 is connected to the telescopic rod of the electric push rod 161.

[0046] By blocking the liquid outlet 28 with the blocking plate 162, it is possible to prevent the water in the cleaning chamber 24 from being directly discharged from the liquid outlet 28 during the cleaning operation, thereby reducing water waste. When it is necessary to blow out the oil and impurities floating on the water surface, the electric push rod 161 is controlled to drive the blocking plate 162 to move upward to release the blockage of the liquid outlet 28. After the oil and impurities floating on the water surface are blown out, the electric push rod 161 is controlled to drive the blocking plate 162 to move downward to re-block the liquid outlet 28.

[0047] See also Figure 2 , Figure 4 and Fig.12A hot air blower 182 is installed on the right side of the base 1, and two upper and lower jet pipes 181 are connected to the right side of the annular cover 3. The jet pipe 181 is connected to the hot air blower 182, the upper jet pipe 181 sprays air obliquely downward, and the lower jet pipe 181 sprays air obliquely upward. A liquid inlet 29 is opened on the upper right side of the wavy partition 22, and the liquid inlet 29 is located on the left side of the jet pipe 181 and is connected to the rinsing chamber 23. Two front and rear windshields 20 are connected to the right side of the top of the inner side of the annular cover 3. The windshield 20 is located on the left side of the jet pipe 181 to prevent hot air from diffusing out of the drying area, ensuring that the heat is concentrated in the drying area, thereby improving the drying efficiency. The width of the windshield 20 is smaller than the diameter of the annular filter plate 82 to avoid blocking the T-shaped lifting rod 6 from driving the screen frame 8 to move.

[0048] The hot air blower 182 is controlled to work, and air can be drawn in from the outside and heated, and then the hot air is transported to the jet pipe 181. The hot air blower 182 is a prior art and is not repeated here. When the rinsed NdFeB follows the screen frame 8 to move between the jet pipes 181 on the upper and lower sides, the jet pipe 181 sprays hot air on the rinsed NdFeB to dry the NdFeB. Since the lower jet pipe 181 sprays air obliquely downward and the upper jet pipe 181 sprays air obliquely upward, the water dripping from the NdFeB and the screen frame 8 can be blown back into the rinsing chamber 23 through the liquid inlet 29 to avoid a large amount of water droplets from being scattered at will.

[0049] An automatic, efficient and environmentally friendly cleaning method for NdFeB includes the following steps:

[0050] S1, inject clean water, connect the two injection tubes 27 to an external infusion device to inject clean water into the rinsing chamber 23 and the cleaning chamber 24;

[0051] S2, pour the cleaning agent into the cleaning chamber 24 and mix it with clean water;

[0052] S3, discharge the material, and put the NdFeB to be cleaned into the screen frame 8 through the access port 31;

[0053] S4, cleaning the NdFeB, controlling the two electric annular slides 4 to open synchronously, so as to drive the T-shaped lifting rod 6 to drive the screen frame 8 to move along the electric annular slide 4, and guide the T-shaped lifting rod 6 to rise and fall through the guide rail 1 5, so that the screen frame 8 enters and exits the cleaning chamber 24 and the rinsing chamber 23 in sequence, and then the NdFeB enters and exits the cleaning chamber 24 and the rinsing chamber 23 in sequence, so as to be cleaned and rinsed. At the same time, the ultrasonic transducer 25 is controlled to work, and ultrasonic waves are generated. The ultrasonic waves are transmitted in the liquid to perform ultrasonic cleaning on the NdFeB;

[0054] S5, drying the NdFeB, controlling the hot air blower 182 to work, delivering hot air to the jet pipe 181, and the jet pipe 181 sprays the hot air on the rinsed NdFeB to dry the NdFeB;

[0055] S6, unloading. When the wedge block 87 on the screen frame 8 approaches and contacts the push block 9 on the same side, the wedge block 87 continues to move and is squeezed by the inclined surface 91 on the push block 9 to retract into the linear slide rail 85 and disengage from the upper support block 88, thereby releasing the lock on the annular filter 83. The annular filter 83 moves downward and is located at the lower side of the inverted T-shaped push plate 11. The NdFeB on the annular filter 83 is pushed out to the guide plate 10 through the inverted T-shaped push plate 11, and the guide plate 10 guides the NdFeB on it backwards.

[0056] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
