Description

Technical Field

[0001] The utility model relates to the technical field of magnetic steels, in particular to a magnetic steel feeding device. Background Art

[0002] Since the magnetic steel in the motor rotor has a laminated structure and is not suitable for being transported by clamping to avoid the magnetic steel from collapsing; moreover, since the magnetic steel has a certain weight, directly adopting the transportation method of vacuum adsorption cannot ensure the adsorption reliability of the magnetic steel; therefore, usually by virtue of the magnetism of the magnetic steel itself, a magnetic conductive part such as an iron block is used to contact the magnetic steel to magnetically adsorb the magnetic steel. However, the transportation method of magnetic adsorption easily causes the iron block to be difficult to release the magnetic steel into the profiling back iron. That is, after the magnetic steel magnetically adsorbed on it by the iron block is placed in the profiling back iron, since the two sides of the magnetic steel are magnetically adsorbed to the profiling back iron and the iron block respectively, manual operation or other auxiliary tooling needs to be set up to ensure that the magnetic steel is separated from the iron block and the magnetic steel remains in the profiling back iron; however, since the manual operation method is time-consuming and laborious and increases the labor cost; and since additional auxiliary tooling needs to be set up, the production cost is increased.

[0036] To make the technical problems solved by the present utility model, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the drawings and through specific implementation manners.

[0037] In this embodiment, a magnetic steel feeding device is proposed, which is used to automatically magnetically adsorb and transfer and place magnetic steel into a profiling back iron; the profiling back iron is a support member that can provide installation support for the magnetic steel, and the structure of the profiling back iron is similar to the structure of the back iron in the rotor of an existing motor.

[0038] Specifically, as Figure 1 and Figure 2 shown, the magnetic steel feeding device includes a connecting component 31, a magnetic attraction part 32, and a pressing part 33; wherein, the connecting component 31 is slidably arranged above the profiling back iron along the Z-axis; the magnetic attraction part 32 has an adsorption position and a feeding position, and the magnetic attraction part 32 is slidably arranged in the connecting component 31 along the Z-axis, so that the magnetic attraction part 32 can slide to the adsorption position or the feeding position according to the use requirements; the pressing part 33 is not magnetically adsorbed to the magnetic steel, the first end of the pressing part 33 is fixedly arranged in the connecting component 31, and the second end of the pressing part 33 passes through the magnetic attraction part 32 and extends outside the connecting component 31; when the magnetic attraction part 32 slides to the adsorption position, the magnetic attraction part 32 is flush with the second end of the pressing part 33 to magnetically adsorb the magnetic steel into the profiling back iron; when the magnetic attraction part 32 is in the feeding position, the magnetic attraction part 32 retracts into the connecting component 31 relative to the pressing part 33, so that the pressing part 33 presses the magnetic steel into the profiling back iron, so that the magnetic attraction part 32 is separated from the magnetic steel.

[0039] In comparison with the prior art, the magnet steel feeding device in this embodiment enables the magnetic attracting member 32 to be slidably arranged along the Z-axis, and a pressing member 33 that will not magnetically adsorb with the magnet steel is additionally arranged in cooperation with the magnetic attracting member 32; by arranging the connecting assembly 31 to be slidable along the Z-axis above the profiling back iron, arranging the magnetic attracting member 32 to be slidable along the Z-axis within the connecting assembly 31, and fixing the first end of the pressing member 33 within the connecting assembly 31, and the second end of the pressing member 33 passes through the magnetic attracting member 32 and extends outside the connecting assembly 31; when it is necessary to adsorb the magnet steel, first make the connecting assembly 31 slide downward along the Z-axis to drive the magnetic attracting member 32 to move closer to the profiling back iron; at the same time, make the magnetic attracting member 32 slide to the adsorption position, at this time the magnetic attracting member 32 is flush with the second end of the pressing member 33, so that the magnetic attracting member 32 magnetically adsorbs the magnet steel and places it within the profiling back iron; when it is necessary to separate the magnet steel from the magnetic attracting member 32, first make the magnetic attracting member 32 located at the feeding position, at this time the magnetic attracting member 32 retracts into the connecting assembly 31 relative to the pressing member 33, so that the pressing member 33 presses the magnet steel into the profiling back iron, thereby enabling the magnetic attracting member 32 to be separated from the magnet steel, ensuring that the magnet steel is left in the profiling back iron after feeding; then make the connecting assembly 31 slide upward along the Z-axis to drive the pressing member 33 to move away from the magnet steel, so that the entire magnet steel feeding device moves away from the profiling back iron; the above-mentioned use of the mutually cooperating pressing member 33 and magnetic attracting member 32 can ensure the smoothness and reliability of feeding the magnet steel into the profiling back iron, and there is no need for manual operation or other auxiliary tooling to ensure the separation of the magnet steel from the magnetic attracting member 32, saving time and effort, saving labor costs, and only need to cooperate with a pressing member 33 on the magnetic attracting member 32, reducing the cost of additionally setting up auxiliary tooling, ensuring that the cost of the entire magnet steel feeding device is relatively low.

[0040] It is worth noting that by making the magnetic attracting member 32 flush with the second end of the pressing member 33; on the one hand, it can prevent the second end of the pressing member 33 from protruding too long relative to the magnetic attracting member 32, thus facilitating the magnetic attracting member 32 to magnetically adsorb the magnet steel and avoiding interference of the pressing member 33 with the operation of the magnetic attracting member 32 to adsorb the magnet steel; on the other hand, it can prevent the second end of the pressing member 33 from extending too short relative to the magnetic attracting member 32, thus facilitating the magnetic attracting member 32 to directly press against the magnet steel while placing the magnet steel within the profiling back iron, ensuring the smooth separation of the magnet steel from the magnetic attracting member 32. Among them, during the whole process, the pressing member 33 will not magnetically adsorb with the magnet steel.

[0041] Furthermore, the material of the magnetic attracting member 32 is a magnetic conductive material, and the shape and size of the magnetic attracting member 32 match the shape and size of the magnet steel, so as to be conducive to ensuring the adsorption stability of the magnetic attracting member 32 to the magnet steel. In this embodiment, the magnetic attracting member 32 can specifically be an iron block. In other embodiments, the magnetic attracting member 32 can also be a structure made of other magnetic conductive materials, which is not limited here.

[0042] Specifically, as Figure 1and Figure 2 As shown in Figure 2 , the connecting component 31 includes an outer frame body 311 and a support ring 312. Among them, the outer frame body 311 is slidably arranged above the profiling back iron along the Z axis; the support ring 312 is arranged around one end of the outer frame body 311, and the magnetic attraction member 32 and the pressing member 33 are respectively located inside the support ring 312. Among them, the outer frame body 311 can be driven by a linear cylinder to slide along the Z axis.

[0043] Furthermore, as Figure 1 and Figure 2 shown, the pressing member 33 includes a top rod 331. The first end of the top rod 331 is fixedly connected inside the support ring 312, and the second end 3311 of the top rod 331 passes through the magnetic attraction member 32 and extends outside the support ring 312. The magnetic attraction member 32 can be flush with the second end 3311 of the top rod 331, and the top rod 331 is used to press the magnet into the profiling back iron.

[0044] By setting the top rod 331, the structure of the pressing member 33 is relatively simple and the cost is low; moreover, the top rod 331 does not occupy too much adsorption area on the magnetic attraction member 32, which can ensure that the magnetic attraction member 32 stably adsorbs the magnet and avoid the problem that the magnet falls off the magnetic attraction member 32. Among them, the material of the top rod 331 is a non-magnetic conductive material, so that the top rod 331 does not have magnetism and ensures that the top rod 331 will not be magnetically adsorbed to the magnet.

[0045] Furthermore, as Figure 1 and Figure 2 shown, the pressing member 33 includes a plurality of top rods 331, and each top rod 331 is spaced through the magnetic attraction member 32, so as to be able to press the magnet into the profiling back iron simultaneously through the plurality of top rods 331, ensuring that the pressing effect of the pressing member 33 on the magnet is better, and thus being able to better ensure the separation of the magnetic attraction member 32 and the magnet. In this embodiment, the pressing member 33 includes two top rods 331. Here, the number of the top rods 331 is not limited.

[0046] Specifically, as Figure 1 and Figure 2 shown, the distance between the end face of the second end 3311 of the top rod 331 and the lower end face of the support ring 312 is 1 mm - 2 mm, which can cooperate with the sliding stroke of the magnetic attraction member 32 on the Z axis, so as to ensure that the magnetic attraction member 32 can slide to be flush with the second end 3311 of the top rod 331.

[0047] Furthermore, as Figure 1 shown, the magnet feeding device further includes a driving component 34. The fixed end of the driving component 34 is connected to one end of the outer frame body 311 where the support ring 312 is not provided, and the driving end of the driving component 34 is connected to the magnetic attraction member 32 to drive the magnetic attraction member 32 to slide along the Z axis.

[0048] Specifically, as Figure 1 andFigure 2 As shown, the driving assembly 34 includes a driving member 341 and a transmission member. Among them, the fixed end of the driving member 341 is connected to one end of the outer frame 311 where the support ring 312 is not provided. The transmission member is arranged inside the outer frame 311. The driving end of the driving member 341 is connected to one end of the transmission member, and the other end of the transmission member is connected to the magnetic attracting member 32. The driving member 341 is used to drive the transmission member to move, so that the transmission member drives the magnetic attracting member 32 to move along the Z-axis inside the support ring 312. In this embodiment, the driving member 341 may specifically be a motor.

[0049] Further, as Figure 2 shown, the transmission member includes a lead screw 344 and a lead screw nut 345. Among them, the lead screw 344 extends along the Z-axis. The lead screw 344 is rotatably arranged inside the outer frame 311. One end of the lead screw 344 is coaxially connected to the output shaft of the driving member 341. The lead screw nut 345 is threadedly sleeved on the lead screw 344. The rotation of the lead screw 344 can drive the lead screw nut 345 to move along the Z-axis on the lead screw 344, and the lead screw nut 345 is used to connect the magnetic attracting member 32. Among them, one end of the lead screw 344 and the output shaft of the driving member 341 are coaxially connected through a coupling 342, and the lead screw 344 is rotatably arranged inside the outer frame 311 through a bearing 343.

[0050] Specifically, as Figure 2 shown, the transmission member further includes a connecting member 346. One end of the connecting member 346 is fixedly connected to the lead screw nut 345, and the other end of the connecting member 346 penetrates into the support ring 312 and is fixedly connected to the magnetic attracting member 32, so as to be able to transmit the linear motion of the lead screw nut 345 to the magnetic attracting member 32 through the connecting member 346, so as to drive the magnetic attracting member 32 to slide along the Z-axis inside the support ring 312. Among them, the connecting member 346 may include a plurality of connecting blocks. In this embodiment, the connecting member 346 includes two mutually connected connecting blocks. Here, the number and shape of the connecting blocks specifically included in the connecting member 346 are not limited, as long as the magnetic attracting member 32 can be driven to move along the Z-axis through the connecting member 346.

[0051] The specific working process of the magnetic steel feeding device in this embodiment is as follows:

[0052] First, make the driving member 341 drive the lead screw 344 to rotate, so as to drive the lead screw nut 345 to linearly move along the Z-axis on the lead screw 344, so as to drive the magnetic attracting member 32 to move downward along the Z-axis through the lead screw nut 345 and the connecting member 346, so that the magnetic attracting member 32 moves to be flush with the second end 3311 of the ejector rod 331. At this time, the magnetic attracting member 32 is located at the adsorption position, so that the magnetic attracting member 32 adsorbs the magnetic steel.

[0053] Then, make the outer frame 311 move downward along the Z-axis to be close to the profiling back iron, so that the magnetic attracting member 32 drives the magnetic steel into the profiling back iron. At this time, the ejector rod 331 presses against the magnetic steel, and the magnetic attracting member 32 adsorbs the magnetic steel.

[0054] Then, drive the lead screw 344 to rotate by the driving member 341, so as to drive the lead screw nut 345 to linearly move along the Z-axis on the lead screw 344, and drive the magnetic attraction member 32 to move upward along the Z-axis through the lead screw nut 345 and the connecting member 346 until the magnetic attraction member 32 completely disengages from the permanent magnet. During the whole process of disengaging from the permanent magnet, the two ejector rods 331 always press the permanent magnet into the profiling back iron.

[0055] Finally, move the outer frame 311 upward along the Z-axis to be away from the profiling back iron, so that the two ejector rods 331 are simultaneously away from the permanent magnet, thereby driving the whole permanent magnet feeding device away from the permanent magnet and the profiling back iron, so as to realize transporting and placing the permanent magnet into the profiling back iron.

[0056] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
