Description
Technical Field
[0001] This invention relates to the field of mechanical equipment technology, and specifically to a magnetic powder spreading mechanism. Background Technology
[0002] With the surge in the use of rare earth permanent magnets, ferrites, and other magnetic materials in new energy, consumer electronics, and automotive motors, there are increasing demands on the rapid and uniform application of protective and insulating powders after packaging. In some scenarios, powder is applied using compressed air spraying, specifically by atomizing the powder with a low-pressure rotary spray gun and then allowing it to settle. However, this method is prone to powder agglomeration and uneven distribution, resulting in poor product isolation pass rates.
[0003] Therefore, this application studies a magnetic powder spreading mechanism that enables more uniform powder spreading and improves product qualification rate. Utility Model Content
[0004] In order to enable more uniform powder application and improve product qualification rate, this application provides a magnetic powder application mechanism.
[0005] This application provides a magnetic powder dispensing mechanism, which adopts the following technical solution: A magnetic material powder spreading mechanism includes a powder spreading component and a transmission component. The powder spreading component is disposed above the transmission component. The powder spreading component includes a hopper, a first driving member, and a roller brush. The hopper has a feed inlet and a discharge outlet. The roller brush is disposed inside the hopper. The discharge outlet is a plurality of through holes opened at the bottom of the hopper. The first driving member drives the roller brush to rotate.
[0006] By adopting the above technical solution, the magnetic material is transported through the transmission component. When the magnetic material is transported into the area below the powder spreading component, the first driving component drives the roller brush to rotate, which agitates and disperses the powder in the hopper and spreads it to the magnetic material below through the bottom through hole until the magnetic material has completely passed through the powder spreading component. At this time, the powder has evenly covered the magnetic material, so that the protective powder or isolation powder on the magnetic material can be evenly distributed, thereby improving the pass rate of product isolation.
[0007] Optionally, the hopper includes a discharge component, which includes a discharge section and a collection section connected to both sides of the discharge section; the collection section is inclined toward the discharge section, the roller brush is located above the discharge section and at least partially located between the collection sections on both sides, and the through hole is opened in the discharge section.
[0008] By adopting the above technical solution, the powder in the hopper can be automatically gathered to the discharge section, ensuring that the roller brush is always in the powder saturation area, and further improving the uniformity of powder spreading.
[0009] Optionally, the through holes are evenly spaced and arranged in an array.
[0010] By adopting the above technical solutions, the uniformity and consistency of powder application are further improved, ensuring uniform coverage of protective powder or isolation powder on the surface of magnetic materials.
[0011] Optionally, the hopper further includes a guide member, the two ends of which are respectively connected to the feed inlet and the discharge member. The guide member has a guide portion that is inclined toward the discharge member.
[0012] By adopting the above technical solution, the powder can be guided smoothly into the discharge part by tilting the guide part towards the discharge part.
[0013] Optionally, the powder-spreading assembly further includes a mounting frame, in which the hopper, the first drive unit, and the roller brush are all disposed. The first drive unit is disposed on one side of the hopper.
[0014] By adopting the above technical solutions, the structure can be rationally distributed, space can be rationally utilized, and space utilization rate can be improved.
[0015] Optionally, the first driving component includes a motor and a belt, with both ends of the belt connected to the output end of the motor and the roller brush, respectively, and the motor drives the belt to rotate the roller brush.
[0016] Optionally, the powder-spraying assembly further includes a second driving member and a blocking member, wherein the second driving member drives the blocking member to move, thereby blocking or opening the through hole.
[0017] By adopting the above technical solution, the powder spreading can be started and stopped, enabling precise powder spreading of the magnetic material when the magnetic material stops, thereby further improving the uniformity of powder spreading.
[0018] Optionally, a receiving box may also be included, which is placed below the discharge port.
[0019] By adopting the above technical solution, the powder leakage problem during start-up and shutdown can be avoided through the receiving box.
[0020] By adopting the above technical solution, before and after powder application, the second driving component drives the blocking component to block the through hole, which can prevent powder leakage and ensure that the powder can be accurately applied to the magnetic material.
[0021] Optionally, the transmission assembly further includes a third driving member, a lead screw, and a transmission seat. The third driving member drives the lead screw to move the transmission seat, and the transmission seat is used to place magnetic materials.
[0022] By adopting the above technical solution, the box is placed on the transmission base, the magnetic material is placed inside the box, and the third driving component drives the lead screw to move the box to the powder spreading component to spread powder evenly. After one layer of magnetic material is powdered, the third driving component drives the lead screw to retract and continue to place magnetic material inside the box. The magnetic material continues to be stacked and the powder spreading operation is repeated. The surface of each layer of magnetic material is evenly powdered until the box is full of magnetic material.
[0023] In summary, this application includes the following beneficial technical effects: 1. The magnetic material is conveyed through the transmission component. When the magnetic material is conveyed to the bottom of the powder spreading component, the conveying stops. The first driving component drives the roller brush to rotate, which agitates and disperses the powder in the hopper and spreads it to the magnetic material below through the bottom through hole, so that the protective powder or isolation powder on the magnetic material can be evenly distributed, thereby improving the product isolation qualification rate. 2. The collecting section can automatically gather the powder in the hopper to the discharge section, ensuring that the roller brush is always in the powder saturation area, further improving the uniformity of powder spreading; 3. The second driving component drives the blocking component to move, thereby starting and stopping the powder spreading. This allows for precise powder spreading of the magnetic material when the magnetic material stops, further improving the uniformity of powder spreading. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.
[0028] This application discloses a magnetic material powder-spreading mechanism. (Refer to...) Figure 1 The magnetic material powder-spreading mechanism includes a powder-spreading component 1 and a conveying component 2. The conveying component 2 is used to convey the magnetic material. The powder-spreading component 1 is positioned above the conveying component 2. When the magnetic material is placed into the box and the box is conveyed by the conveying component 2 to the area below the powder-spreading component 1, the powder-spreading component 1 spreads powder onto the magnetic material inside the box until the box has completely passed through the powder-spreading component 1. At this point, the magnetic material inside the box is evenly powdered, thus improving the powder-spreading efficiency. The conveying component 2 drives the box to retract and continue stacking the next layer of magnetic material on top of the previous layer, and then it continues to enter the powder-spreading component 1 for powder spreading. This process is repeated until the box is full of magnetic material.
[0029] Reference Figure 2 and Figure 3 The powder-spreading assembly 1 includes a hopper 11, a first driving component 12, and a roller brush 13. The hopper 11 has an inlet 3 and an outlet 4. The roller brush 13 is disposed inside the hopper 11. The inlet 3 is located above the hopper 11 and is covered by an openable cover. The outlet 4 consists of several through holes located at the bottom of the hopper 11. The first driving component 12 drives the roller brush 13 to rotate. The bristles of the roller brush 13 are made of nylon, and the length of the bristles is adapted to the required thickness of the powder. The roller brush 13 disperses the powder and evenly spreads it onto the magnetic material through the through holes at different locations, so that the protective powder or isolation powder on the magnetic material can be evenly distributed, improving the pass rate of product isolation.
[0030] In some embodiments, the hopper 11 includes a discharge component 111, which includes a discharge section 112 and a collection section 113 integrally connected to both sides of the discharge section 112. The collection section 113 is inclined toward the discharge section 112 and is arc-shaped. The roller brush 13 is located above the discharge section 112 and at least partially between the collection sections 113 on both sides. In this embodiment, the lower half of the roller brush 13 along the axis is located between the collection sections 113 on both sides, and a through hole is formed in the discharge section 112. This allows the powder in the hopper 11 to be automatically gathered to the discharge section 112, ensuring that the roller brush 13 is always in the powder saturation area, further improving the uniformity of powder distribution.
[0031] In some embodiments, the through holes are evenly spaced and arranged in an array. In this embodiment, the through holes are evenly spaced along the length and width of the discharge section 112, which allows for more uniform powdering of the magnetic material.
[0032] Continue to refer to Figure 2In some embodiments, the hopper 11 further includes a guide member 114, with its two ends connected to the inlet 3 and the outlet 111, respectively. In this embodiment, the inlet 3 is formed by the guide member 114, which has a guide portion 141 that is inclined toward the outlet 111. In this embodiment, the guide member 114 and the outlet 111 are fixed together by screws. This allows the guide member 114 to accommodate more powder and facilitates the introduction of powder into the outlet 111.
[0033] In some embodiments, the powder-spreading assembly 1 further includes a mounting frame 14, in which the hopper 11, the first drive member 12, and the roller brush 13 are all disposed. The first drive member 12 is disposed on one side of the hopper 11. In this embodiment, the guide member 114 is integrally bent into the hopper 14 through the mounting frame 14, and the first drive member 12 is disposed below the guide portion 141, which allows for a reasonable layout, minimizing space occupation while increasing the space of the hopper 11 and improving space utilization.
[0034] Reference Figure 3 In some embodiments, the first driving member 12 includes a motor and a belt, with both ends of the belt connected to the output end of the motor and the roller brush 13, respectively. The motor drives the belt to rotate the roller brush 13, thereby enabling the roller brush 13 to rotate stably.
[0035] In some embodiments, the powder-spreading assembly 1 further includes a second driving member 15 and a blocking member 16. The second driving member 15 drives the blocking member 16 to move, thereby blocking or opening the through hole. In this embodiment, the second driving member 15 is a cylinder, which is located below the motor to further improve space utilization. The blocking member 16 is located below the hopper 11. When the magnetic material is not in place, the blocking member 16 blocks the through hole to prevent powder from leaking down. When the magnetic material is in place, the cylinder drives the blocking member 16 to move and open the through hole, allowing the powder to be spread down along the through hole, thus spreading powder onto the magnetic material more accurately and evenly.
[0036] Reference Figure 1 and Figure 3 In some embodiments, a receiving box 5 is also included, which is placed below the discharge port 4. A base is also included, which is mounted on the transmission assembly 2. The powder spreading assembly 1 is mounted on the base, and the receiving box 5 is placed on the base and located below the discharge port 4. Before the blocking member 16 blocks or opens the through hole, the receiving box 5 is placed on the base and located below the blocking member 16. After the blocking member 16 completely blocks or opens the through hole, the receiving box 5 is removed, which can prevent powder leakage and further improve the uniformity of magnetic material powder spreading.
[0037] Refer again Figure 1In some embodiments, the transmission assembly 2 further includes a third drive component 21, a lead screw 22, and a transmission seat 23. The third drive component 21 drives the lead screw 22 to move the transmission seat 23, which is used to hold the magnetic material. A limiting block for the limiting box is provided on the transmission seat 23, allowing the box to be placed on the transmission seat 23 and the magnetic material placed inside, thus making the box more stable during transmission. A guide rail is also provided, which cooperates with the transmission seat 23 to guide it. The third drive component 21 is a third motor, which drives the lead screw 22 to move the transmission seat 23 along the guide rail, conveying the box to the area below the powder-spreading assembly 1 to spread powder on the magnetic material. After powder spreading, the material is then transported downstream.
[0038] The implementation principle of a magnetic material powdering mechanism in this application embodiment is as follows: the magnetic material is transported through the transmission component 2. When the magnetic material is transported to the bottom of the powdering component 1, the transmission is stopped. The first driving component 12 drives the roller brush 13 to rotate, which stirs and disperses the powder in the hopper 11 and sprinkles it onto the magnetic material below through the bottom through hole, so that the protective powder or isolation powder on the magnetic material can be evenly distributed, thereby improving the pass rate of product isolation.
