Description

Technical Field

[0001] This utility model relates to the field of magnet separation technology, and in particular to a magnet separation mechanism. Background Technology

[0002] A permanent magnet brushless motor is a permanent magnet motor controlled by electronic circuit commutation or current. The magnet is a crucial component in the motor's structure; it is a strongly magnetic object that generates a magnetic field through a frequency converter to drive the motor. Depending on the motor's structure, magnets come in various shapes and types. Current types include rectangular magnets for servo motors, arc-shaped magnets for DC brushless motors, sector-shaped magnets for AC motors, and tubular magnets for micro-motors. The tubular magnets, typically supplied to the factory in rows of approximately 12, need to be separated individually from their initial adsorption by spacers before assembly. This process is usually done manually. However, due to the strong magnetic attraction of the magnets, workers need to exert considerable force (around 40N) to pry them apart manually. Therefore, prolonged manual magnet separation is extremely strenuous for workers, requiring frequent breaks before resuming the work, resulting in low efficiency. Furthermore, because magnets have strong magnetic attraction between adjacent magnets and to ferromagnetic materials, and because magnets are brittle, magnetic collisions easily occur between adjacent magnets and between magnets and ferromagnetic materials. This can easily cause magnet breakage or injuries to workers' hands when adjacent magnets attract each other, posing challenges to enterprise safety and magnet separation operations. Utility Model Content

[0003] To address the technical problems of low efficiency in magnet separation due to manual operation in existing technologies, and the ease with which magnetic collisions can easily occur between adjacent magnets or between magnets and ferromagnetic materials, leading to magnet breakage or hand injuries to workers when adjacent magnets are attracted, thus causing trouble for enterprise safety and magnet separation work, this utility model provides the following technical solution.

[0004] This utility model discloses a magnet separation mechanism, including a workbench and a base located on one side of the upper part of the workbench. A push cylinder is fixedly provided on one side of the workbench facing the base. A receiving component is detachably connected to the upper part of the base. The receiving component includes a first receiving member and a second receiving member with the same structure and arranged opposite to each other to receive a magnet assembly. The lower part of the first receiving member and the second receiving member are provided with a venting groove for the lowest magnet of the magnet assembly to pass through. A limiting member is provided on the side of the two venting grooves away from the push cylinder. A receiving box is provided on one side of the workbench, located diagonally below the limiting member. A push plate is fixedly connected to the output end of the push cylinder. The axis of the push plate is on the same straight line as the diameter of the lowest magnet.

[0005] As a further technical solution, a pushing block is fixedly connected to one end of the pushing plate facing the magnet, and the end of the pushing block facing the magnet matches the shape of the magnet.

[0006] As a further technical solution, the upper surface of the push block is provided with a wedge-shaped piece for hooking the pad, and a fixing block corresponding to the push block is provided on one side of the base. The fixing block is fixedly connected to a positive pressure connecting pipe connected to an external positive pressure device. The positive pressure connecting pipe is provided with a flat blowing port on the side facing the push block, and a collection box is provided on the upper part of the base opposite to the flat blowing port.

[0007] As a further technical solution, the first receiving member includes a matching surface that matches the magnet assembly and a vent groove through which the axis passes.

[0008] As a further technical solution, the limiting member includes an inverted U-shaped limiting plate and a limiting groove for the magnet to pass through.

[0009] As a further technical solution, the workbench is provided with a slide that is inclined toward the receiving box and baffles located on both sides of the slide at one end near the receiving box.

[0010] The beneficial effects of this utility model are as follows: The receiving component can effectively accommodate the magnet assembly, and the emptying slot below the receiving component is for placing the lowest magnet. The emptying slot and the limiting slot cooperate to allow individual magnets to pass through. A pushing cylinder drives a pushing block to separate the individual magnet in the emptying slot from the magnet assembly, allowing the individual magnet to pass through the limiting slot and fall into the receiving box. The separation operation is stable, reliable, and accurate, with high automatic magnet separation efficiency. Simultaneously, the wedge-shaped plate on the upper surface of the pushing block can also separate the gasket from the magnet, reducing interference from the gasket during magnet separation. Furthermore, the magnet separation operation reduces manual operation, decreasing the possibility of worker injury and ensuring safe production for the enterprise. Both the receiving component and the limiting component are detachably connected to the base. By replacing different specifications of the receiving component and limiting component, this utility model's magnet separation mechanism is applicable to the separation of tubular magnets of different specifications, exhibiting good versatility.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0013] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0014] like Figure 1 As shown, the present invention provides a magnet separation mechanism, including a worktable 1 and a base 2 located on one side of the upper part of the worktable 1. A push cylinder 3 is fixedly provided on one side of the worktable 1 facing the base 2. To ensure the accuracy of pushing and separating the magnet, the push cylinder 3 is a three-axis cylinder.

[0015] like Figure 2 and Figure 3As shown, in a preferred embodiment, a receiving component 6 is detachably connected to the upper part of the base 2. The receiving component 6 is used to receive the magnet assembly 10. In this embodiment, the magnet assembly 10 is composed of twelve magnets 11 stacked vertically, and a spacer 12 is provided between adjacent magnets 11, so that the magnet assembly 10 forms a columnar structure. A limiting component 7 is provided on one side of the receiving component 6. The limiting component 7 includes an inverted U-shaped limiting plate 701 and a limiting groove 702 for the magnets 11 to pass through. The limiting plate 701 is detachably connected to the upper part of the base 2 by bolts. The height of the limiting groove 702 is slightly greater than the height of the magnets 11, but less than the height of the magnets 11 plus the spacer 12. Thus, after the cylinder 3 pushes the magnets 11 away from the magnet assembly 10, the spacer 12 remains at the bottom of the magnet assembly 10.

[0016] In a preferred embodiment, a receiving box 13 is provided on one side of the workbench 1, located diagonally below the limiting member 7. After the magnet 11 is separated individually, it falls from the limiting groove 702 into the receiving box 13 and is promptly removed by the operator. To prevent the separated magnet 11 from moving in different directions, a slide 102 inclined towards the receiving box 13 is provided at one end of the workbench 1 near the receiving box 13. At the same time, baffles 101 are provided on both sides of the slide 102. The combined design of the baffles 101 and the slide 102 ensures that the separated magnet 11 falls accurately into the receiving box 13.

[0017] In a preferred embodiment, a push plate 4 is fixedly connected to the output end of the push cylinder 3. The push plate 4 has a plate-like or rod-like structure. One end of the push plate 4 is detachably connected to the output end of the push cylinder 3, and the other end of the push plate 4 is connected to a push block 5. The axis of the push plate 4 is on the same straight line as the diameter of the lowest magnet 11, which ensures that the pushing force of the push plate 4 accurately pushes the tubular magnet 11. At the same time, the push block 5 has a fitting surface, the shape of which matches the shape of the magnet 11, further ensuring accurate pushing of the magnet 11.

[0018] like Figure 2 and Figure 4 As shown, in a preferred embodiment, the receiving component 6 includes a first receiving member 601 and a second receiving member 602 that receive the magnet assembly 10. The first receiving member 601 and the second receiving member 602 have the same structure and are arranged opposite to each other. The first receiving member 601 and the second receiving member 602 have the same structure. Only the first receiving member 601 will be described in detail below. The first receiving member 601 includes a matching surface 603 that matches the shape of one side of the magnet assembly 10. The matching surface 603 facilitates the reception of the magnet assembly 10. It also includes a venting groove 604 whose axis passes through the matching surface 603. The venting groove 604 facilitates the smooth descent of the magnet assembly 10.

[0019] In a preferred embodiment, both the first receiving member 601 and the second receiving member 602 are provided with venting grooves 605 at their lower parts for the passage of the lowest magnet 11 in the magnet assembly 10. The lateral length of the groove formed by the two venting grooves 605 is greater than the diameter of the magnet 11, facilitating the movement of the magnet 11. The side of the two venting grooves 605 away from the pushing cylinder 3 corresponds to the limiting groove 702. At this time, a pushing block 5 is fixedly connected to the end of the pushing plate 4 facing the magnet 11. The end of the pushing block 5 facing the magnet 11 matches the shape of the magnet 11. Thus, the pushing cylinder 3 can make the pushing block 5 accurately push the lowest magnet 11 in the magnet assembly 10 away, so that the magnet 11 passes through the venting groove 605, passes through the limiting groove 702, and falls into the receiving box 13. Afterwards, the worker can promptly remove the individual magnet 11 to prevent the next magnet 11 from being magnetically attracted to it.

[0020] like Figure 2 and Figure 5 As shown, in a preferred embodiment, the upper surface of the push block 5 is provided with a wedge-shaped piece 501 for hooking the pad 12. When the push block 5 pushes the current magnet 11 to move towards the limiting groove 702, the wedge-shaped piece 501 only contacts the pad 12 above the current magnet 11 without hooking it. After the push block 5 pushes the current magnet 11 away, when the push block 5 retracts, the wedge-shaped piece 501 can hook the pad 12 that was in contact above, and cause the pad 12 to retract together with the push block 5. At this time, a fixing block 201 corresponding to the push block 5 is provided on one side of the base 2. The position of the fixing block 201 corresponds to the retracted push block 5. The fixing block 201 is fixedly connected to a positive pressure connecting pipe 8 connected to an external positive pressure device. The external positive pressure device provides compressed air, causing the positive pressure connecting pipe 8 to blow out high-pressure air. Meanwhile, a flat blowing port 9 is provided on the side of the positive pressure connecting pipe 8 facing the push block 5. The flat blowing port 9 can blow away the pad 12 above the push block 5. A collection box 14 is provided on the upper part of the base 2 on the side opposite to the flat blowing port 9. The flat blowing port 9 blows the pad 12 into the collection box 14.

[0021] It should be understood that an existing photoelectric switch can be installed on one side of the base 2. The photoelectric switch detects the position of the magnet 11 throughout the entire process from its ejection to its unloading, and the PLC controller executes the opening and closing actions, thereby controlling the operation of the push cylinder 3 and realizing the automation process. The installation and use of the photoelectric switch and the PLC controller both adopt existing technologies, so they will not be described in detail here.

[0022] In use, this invention first selects a suitable receiving component 6 and a limiting component 7 based on the height and size of the magnet 11 to be separated and installs them on the base 2. Then, the magnet assembly 10 is placed into the receiving component 6, and the pushing cylinder 3 is activated. The pushing cylinder 3 drives the pushing block 5 to push the bottom magnet 11 from the venting groove 605 and through the limiting groove 702. After that, the magnet 11 falls into the receiving box 13 and is promptly removed by the staff. Then, the pushing block 5 retracts, and the wedge-shaped plate 501 hooks out the pad 12 above the pushing block 5. Then, the pad 12 retracts to its original position along with the pushing block 5, and the flat blowing port 9 blows the pad 12 into the collection box 14. Then, the next separation operation can be continued.

[0023] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
