Description

Technical Field

[0001] The invention relates to the field of NdFeB material processing, and in particular to an automatic cleaning device for NdFeB materials. Background Art

[0002] During the production process of NdFeB materials, oil stains, dust and other particulate impurities are easily left on their surfaces. In the next process of NdFeB materials, such as surface treatment to prevent oxidation, the NdFeB materials need to be cleaned to remove impurities on their surfaces. Currently, there are grinding and ultrasonic cleaning methods for cleaning NdFeB materials, but grinding can easily cause large losses to NdFeB materials, and the processing cost is high and the efficiency is low. Currently, ultrasonic cleaning of NdFeB materials is a low-cost and high-efficiency process, but most NdFeB products are non-standard products, and a considerable number of products still require direct manual participation when using ultrasonic cleaning, that is, when NdFeB materials are ultrasonically cleaned, most of them are placed manually. In the ultrasonic cleaning equipment, the NdFeB material needs to be frequently turned over manually using rods or clamps, but this will damage the fragile NdFeB material, and the speed is slow and the efficiency is low. After the material in the ultrasonic cleaning equipment is turned over, the cleaning fluid of the ultrasonic cleaning equipment will also fluctuate, resulting in the appearance of noise in the cleaning fluid, thereby weakening the energy carried by the vibration wave generated by the transducer in the ultrasonic cleaning box; there is also a method of using a net bag to load the NdFeB material and placing it in an ultrasonic cleaning box for ultrasonic cleaning. Although this method can clean more materials at a time, the net bag outside the material is easy to interfere with the vibration wave transmitted to the cleaning fluid by the ultrasonic wave in the ultrasonic cleaning equipment, and will also reduce the vibration wave energy acting on the NdFeB material.

The lower side of the assembly frame 1 is fixedly connected with the ultrasonic cleaning box 2, the upper side of the assembly frame 1 is fixedly connected with the interconnection frame 3, the lower side of the ultrasonic cleaning box 2 is fixedly connected with the extension pipe 4, the extension pipe 4 and the ultrasonic cleaning box 2 are interconnected, the lower side of the extension pipe 4 is connected with a seal 41, the seal 41 is a sealing ring made of rubber, the sealing 41 is sleeved with a mounting pipe 5, the upper side of the mounting pipe 5 extends into the ultrasonic cleaning box 2 and is fixedly connected with the assembly chassis 6, the assembly chassis 6 and the mounting pipe 5 are interconnected, and the assembly A fixing frame 61 is fixedly connected inside the chassis 6, and a waterproof folding layer 7 is fixedly connected to the outer periphery of the assembly chassis 6. The waterproof folding layer 7 is a foldable plastic material structure. An assembly top plate 8 is fixedly connected to the upper side of the waterproof folding layer 7. An immersion mechanism 9 is provided at the extension tube 4. The mounting tube 5 is fixedly connected to the immersion mechanism 9. The immersion mechanism 9 is used to drive the mounting tube 5 to move up and down. A separation mechanism 10 is provided between the assembly top plate 8 and the fixing frame 61. The assembly top plate 8 is on the same center line with the assembly chassis 6 through the connection of the separation mechanism 10. A discharge mechanism 11 is provided at the assembly top plate 8. The discharge mechanism 11 is used to place neodymium iron boron materials. The separation mechanism 10 is used to separate the contact between the discharge mechanism 11 and the materials. A reversing mechanism 12 is provided on the upper side of the fixing frame 61. The reversing mechanism 12 is used to control the rotation of the discharge mechanism 11.

[0039] When the NdFeB material is ultrasonically cleaned, a cleaning liquid can be prepared according to the impurities contained on the surface of the NdFeB material to be cleaned, and the cleaning liquid can be placed in the ultrasonic cleaning box 2. Then, the ultrasonic cleaning box 2 can be started to transmit the ultrasonic wave to the cleaning liquid through the transducer of the ultrasonic cleaning box 2. At this time, the immersion mechanism 9 can be controlled to start running, so that the immersion mechanism 9 drives the installation tube 5 to move downward, so that the installation tube 5 drives the assembly bottom plate 6, the assembly top plate 8, the separation mechanism 10, the reversing mechanism 12 and the discharge mechanism 11 to move downward until the immersion mechanism 9 moves downward to its lower end. At this time, the immersion mechanism 9 can be controlled to start running. The separation mechanism 10 is controlled to operate, so that the separation mechanism 10 drives the discharge mechanism 11 to operate downward, so that the discharge mechanism 11 is separated from the contact with the NdFeB material thereon. At this time, the NdFeB material at this position will be supported by the reversing mechanism 12. At this time, the NdFeB material is supported by multiple points instead of a large area, so that the outer surface of the NdFeB material can be more fully contacted with the vibrating cleaning liquid, and the impurities generated after cleaning with the vibrating cleaning liquid can be mixed in the cleaning liquid more quickly, avoiding the problem of impurities accumulating at the bottom of the NdFeB material and still adhering to it after cleaning; at this time, the control can be continued The operation of the reversing mechanism 12 will slowly drive the NdFeB material supported thereon to rotate, so that the NdFeB material can rotate slowly in the vibrating cleaning liquid, so that the outer surface of the NdFeB material can pass through the interference enhancement area of ​​the cleaning liquid vibration wave with a greater probability, avoiding the occurrence of cleaning dead corners caused by no displacement when the NdFeB material is automatically cleaned. Compared with the traditional ultrasonic cleaning process, that is, the method of manually using a rod tool or a clamping tool to move the material being cleaned, it can protect the NdFeB material with low hardness without contacting the material without causing missing corners. The disadvantages of this invention are that after the time required for cleaning the NdFeB material, the reversing mechanism 12 can be controlled to stop running, and then the separation mechanism 10 can be controlled to reset so that the discharging mechanism 11 contacts the NdFeB material again, and then the immersion mechanism 9 is controlled to reset so that the discharging mechanism 11 drives the NdFeB material to move upward and leave the ultrasonic cleaning box 2, and then the NdFeB material can be transferred to the next processing step; in the process of the NdFeB material moving up and down in and out of the ultrasonic cleaning box 2, the discharging mechanism 11 and the NdFeB material are transported in surface-to-surface contact, which can provide the stability of the transfer.

[0040] Example 2: Figure 3 As shown, the immersion mechanism 9 includes an electric guide rod 91 and a bracket 92. The electric guide rod 91 is fixedly connected to the outside of the extension tube 4. The moving part of the electric guide rod 91 is fixedly connected to the bracket 92. The bracket 92 is fixedly connected to the lower side of the mounting tube 5.

[0041] The electric guide rod 91 is started and controlled, and the electric guide rod 91 can drive its moving part to move up and down, so that the bracket 92 drives the mounting pipe 5 to move up and down, so that the discharge structure can enter and exit the ultrasonic cleaning box 2.

[0042] like Figure 7-Figure 8 As shown, the separation mechanism 10 includes a moving pair 102 and an electric push rod 103. The moving pair 102 is fixedly connected to both sides of the fixed frame 61. The moving pair 102 is a linear moving pair matched with a guide rail and a guide sleeve. The moving parts of the moving pair 102 are connected to each other. The electric push rod 103 is fixedly connected to the upper side of the mounting tube 5. The moving part of the electric push rod 103 is connected to the moving part of the moving pair 102. The upper side of the moving part of the moving pair 102 is fixedly connected to the assembly top plate 8.

[0043] Start and control the electric push rod 103, the moving part of the electric push rod 103 will drive the moving part of the moving pair 102 to move, thereby driving the assembly top plate 8 to move, and the displacement between the assembly bottom plate 6 and the assembly top plate 8 is compensated by the waterproof folding layer 7; when the assembly top plate 8 is driven to move downward, the assembly top plate 8 will also move downward at the reversing mechanism 12, at this time, the assembly top plate 8 and the discharge mechanism 11 will be out of contact with the NdFeB material, so that the reversing mechanism 12 supports the NdFeB material, that is, the surface contact is converted into multi-point contact.

[0044] like Figure 5-Figure 9 As shown, the discharge mechanism 11 includes an annular slide rail 111, a sealing ring sleeve 112 and a discharge plate 113. The annular slide rail 111 is fixedly connected to the inner wall of the upper side of the assembly top plate 8. The upper periphery of the assembly top plate 8 is fixedly connected with a sealing ring sleeve 112. The sealing ring sleeve 112 is an annular rubber ring.

The discharge plate 113 is a structure with array openings. The accessories of the reversing mechanism 12 are in the array openings of the discharge plate 113 and keep the periphery sealed.

[0045] When the assembly top plate 8 moves downward, the assembly top plate 8 will drive the annular slide rail 111, the sealing ring sleeve 112 and the discharge plate 113 to move downward, and the discharge plate 113 will also move downward through its array-type opening structure, so that the reversing mechanism 12 moves upward relative to the discharge plate 113 through its array-type openings, thereby causing the NdFeB material on the discharge plate 113 to break away from contact with it, and then convert it into multi-point contact with the reversing structure; and when the reversing mechanism 12 rotates, the reversing mechanism 12 will drive the NdFeB material supported above it to rotate, and will also drive the discharge plate 113 to rotate through the annular slide rail 111.

The rotating frame 122 is an array-type split structure. The array-type split structure of the rotating frame 122 is fixedly connected with a separation support rod 123. Each separation support rod 123 extends into each opening structure of the discharge plate 113 above it and maintains the outer periphery sealed.

[0047] When the discharge plate 113 moves up and down through the control of the electric push rod 103, the discharge plate 113 will move on the separation support rod 123 through its array-type open hole structure, so that the separation support rod 123 moves relatively in the open hole structure of the discharge plate 113; when the discharge plate 113 is not moved under the control of the electric push rod 103, the NdFeB material is on the discharge plate 113, and the bottom of the NdFeB material is in contact with the surface of the discharge plate 113. When the electric push rod 103 is controlled to drive the discharge plate 113 to move downward, the NdFeB material will be out of contact with the surface of the discharge plate 113 and come into contact with the separation support rod 123. The separation support rod 123 can make the NdFeB material contact with the cleaning liquid over a larger area, and at the same time increase the height distance between the bottom surface of the NdFeB material and the discharge plate 113.

[0048] like Figure 10-13 As shown, it also includes a material transport mechanism 13, which includes an electric slide 131, a sliding frame 132, a pushing frame 133 and a guide assembly 14.

The operation interval of the external conveyor belt 17 is set according to the operation time of one cycle of the automatic cleaning device for boron materials; during the automatic cleaning process, the electric slide 131 and the external conveyor belt 17 can be started to control the upper level of the external conveyor belt 17 to place the materials individually when placing the materials, which belongs to the prior art; the electric slide 131 will drive the sliding frame 132 and the pushing frame 133 to move to the right through its moving parts, so that the two pushing frames 133 move, and the left pushing frame 133 will drive the neodymium iron boron material on the left external conveyor belt 17 The material moves to the right, and the right push rack 133 also moves to the right at this time. If there is a cleaned NdFeB material on the discharge plate 113 at this time, the right push rack 133 will push the NdFeB material to the right direction to the right external conveyor belt 17. In the process of the push rack 133 running to the right, the left push rack 133 will drive the uncleaned NdFeB material to be placed above the discharge plate 113. At this time, the operation of the immersion mechanism 9 can be controlled to immerse the NdFeB material in the cleaning liquid in the ultrasonic cleaning box 2. At this time, the electric slide 131 can be controlled to perform re-cleaning. position, and controls the external conveyor belt 17 to run intermittently to transport the next NdFeB material, and the NdFeB material that has been cleaned on the right external conveyor belt 17 will also be transported synchronously until it reaches the next processing step, and when the NdFeB material is pushed by the pushing rack 133, the guide assembly 14 will provide displacement support; in this way, through the operation of the two pushing racks 133, the NdFeB material can be automatically placed and pushed out of the discharge plate 113, which can further improve the cleaning efficiency of non-standard NdFeB materials produced in batches.

[0050] like Figure 11-13 As shown, the guide assembly 14 includes a guide frame 141 and a combined frame 142. The guide frame 141 is fixedly connected to the upper right position of the ultrasonic cleaning box 2, and the combined frame 142 is fixedly connected to the upper left position of the ultrasonic cleaning box 2. The guide frame 141 is used to connect the position between the discharge plate 113 and the right external conveyor belt 17, and the combined frame 142 is used to connect the position between the discharge plate 113 and the left external conveyor belt 17.
