Referring to fig. 1, a magnetic steel inserting apparatus 10 according to a preferred embodiment of the present invention includes an inserting mechanism 100, an adapting mechanism 200, and a feeding mechanism 300.

The magnet steel insertion device 10 is used for inserting magnet steel (not shown) into the rotor 20. As shown in fig. 6, the rotor 20 has a plurality of mounting holes 21 formed along the circumferential direction, and the magnetic steel insertion device 10 can insert a plurality of magnetic steels into the plurality of mounting holes 21. The alnico device 10 generally further includes a bottom plate 400, and the inserting mechanism 100, the adapting mechanism 200, and the feeding mechanism 300 can be mounted on the bottom plate 400. The plug mechanism 100 can simultaneously insert a plurality of magnetic steels into a plurality of mounting holes 21 of the rotor 20 to achieve assembly. The inserting mechanism 100 is generally fixedly installed at an assembling station, and can enter the assembling station when the rotor 20 needs to be assembled.

Referring to fig. 2, the plugging mechanism 100 includes a first power assembly 110 and a plurality of pressing rods 120, wherein the first power assembly 110 can drive the plurality of pressing rods 120 to move along an extending direction of the pressing rods 120, i.e., up and down direction. The first power assembly 110 may be a cylinder, an electric cylinder, or a motor screw nut set, and the plurality of pressing rods 120 extend in the same direction. The first power assembly 110 can simultaneously drive the plurality of pressing rods 120 to move, and the plurality of pressing rods 120 can respectively push the plurality of magnetic steels. It can be seen that the positions of the plurality of pressing rods 120 need to be configured to correspond to the positions of the plurality of mounting holes 21.

Specifically, in the present embodiment, the plugging mechanism 100 further includes a support 130, a connecting plate 140 and a guide 150.

The support 130 plays a supporting role, and the first power assembly 110 is fixedly arranged on the support 130. The connecting plate 140 is fixedly connected to the driving end of the first power assembly 110, and the plurality of pressing rods 120 are fixed to a side of the connecting plate 140 facing away from the first power assembly 110. The coupling plate 140 is slidably mounted to the holder 130 in the extending direction of the pressing lever 120 by a guide 150. The first power assembly 110 can drive the plurality of pressing rods 120 to move simultaneously by driving the connection plate 140. Moreover, the guide 150 can prevent the plurality of pressing rods 120 from shaking during the extension and contraction process.

Optionally, the guiding element 150 is a plurality of guiding rods, and the plurality of guiding rods are slidably disposed on the support 130. Each guide rod is extended in the same direction as the pressing rod 120 and has one end fixed to the connection plate 140. The guide bar and the support 130 can be connected through a linear bearing so that the guide bar can slide smoothly.

Referring to fig. 3 and 4, the adapting mechanism 200 includes a second power assembly 210 and a transition plate 220. The second power assembly 210 may be a cylinder, an electric cylinder, or a motor screw nut set, and the transition plate 220 is generally shaped like a disk. The transition disk 220 is provided with a plurality of slots 221 along the circumferential direction, and each slot 221 can contain magnetic steel therein. The number and positions of the slots 221 on the transition disk 220 correspond to the number and positions of the mounting holes 21 in the rotor 20.

Further, the second power assembly 210 can drive the transition disc 220 to move between the loading station and the assembling station. Specifically, the transition disc 220 may be mounted on the bottom plate 400 through a structure such as a linear rail slider, and the second power assembly 210 drives the transition disc 220 to slide along the linear rail, so that the transition disc 220 moves between the loading station and the assembling station. When the transition disc 220 is at the feeding station, the magnetic steel can be conveniently loaded into the clamping groove 221 of the transition disc 220.

The feed mechanism 300 includes a positioning plate 320, the positioning plate 320 being capable of carrying and positioning the rotor 20. The positioning plate 320 may be provided with a positioning element 321, such as a positioning block or a positioning pin, for positioning the rotor 20. Taking fig. 6 and 7 as an example, the positioning plate 320 is provided with a positioning block as the positioning member 321, the positioning block is provided with a key slot (not shown), the rotor 20 is provided with a boss, and the boss and the key slot are matched to position the rotor 20 on the positioning plate 320.

Further, the positioning plate 320 can be fixedly installed at the assembling station, and the position can be adjusted under the driving of the power assembly. Specifically, in this embodiment, the feeding mechanism 300 further includes a third power assembly 310, and the third power assembly 310 can drive the positioning plate 320 to move between the rotor feeding station and the assembling station. The third power assembly 310 may be a pneumatic cylinder, an electric cylinder, or a motor screw nut assembly. When locating plate 320 is located rotor material loading station, can conveniently pack the rotor into locating plate 320.

Specifically, the feeding mechanism 300 further includes a second moving plate 330, and the positioning plate 320 is mounted on the second moving plate 330. The second moving plate 330 can be mounted on the bottom plate 400 through a linear rail slider, and the third power assembly 310 is in transmission connection with the second moving plate 330 and can drive the second moving plate 330 to slide along a linear rail, so as to drive the positioning plate 320 to adjust the position.

At the assembling station, the first power assembly 110 can drive the plurality of pressing rods 120 to be inserted into the plurality of slots 221 respectively, and push the magnetic steels in the plurality of slots 221 into the plurality of mounting holes 21 of the rotor 20 positioned on the positioning plate 320 respectively.

Specifically, at the assembly station, the plugging mechanism 100, the transition plate 220 and the positioning plate 320 are stacked in the vertical direction. Moreover, the plugging mechanism 100 is located on a side of the transition disc 220 opposite to the positioning plate 320, and the plurality of pressing rods 120, the plurality of slots 221 on the transition disc 220, and the plurality of mounting holes 21 of the rotor 20 on the positioning plate 320 are arranged in a one-to-one correspondence manner. Thus, when the first power assembly 110 drives the plurality of pressing rods 120 to extend towards the transition disc 220, the plurality of pressing rods 120 can be respectively inserted into the plurality of clamping slots 221 and push the magnetic steel in each clamping slot 121 into the corresponding mounting hole 21.

Therefore, the magnetic steel inserting device 10 can insert a plurality of magnetic steels into the rotor 20 at one time, and the magnetic steels are not required to be inserted into the rotor for positioning once, so that the assembly efficiency can be obviously improved. After the magnetic steel is installed in the rotor 20, magnetic flux detection is also required. During the magnetic flux detection process, the transition plate 220 is moved out of the assembly station, so that a plurality of magnetic steels can be loaded into the transition plate 220 again to prepare for the next assembly. That is, the magnetic steel turning-in transition plate 220 and the magnetic flux detection can be performed simultaneously, so that the time interval between two assembling operations can be shortened.

Referring to fig. 5, in the present embodiment, the adapting mechanism 200 further includes a first moving plate 230, a lifting plate 240 and a fourth power assembly 250.

The first moving plate 230 can be mounted on the bottom plate 400 through a linear rail slider, the first moving plate 230 is in transmission connection with the second power assembly 210, and the second power assembly 210 can drive the first moving plate 230 to slide along a linear rail. The lifting plate 240 is mounted to the first moving plate 230 and can be lifted and lowered with respect to the first moving plate 230, and the transition tray 220 is mounted to the lifting plate 240. Specifically, a plurality of second guide rods 231 are vertically disposed on a surface of the first moving plate 230, and the lifting plate 240 is slidably mounted on the second guide rods 231 to achieve lifting.

The fourth power assembly 250 may be a pneumatic cylinder, an electric cylinder, or a motor screw nut set. When the fourth power assembly 250 is a cylinder, the cylinder body thereof can be fixed to the lifting plate 240, and the moving end thereof is fixed to the first moving plate 230. When the transition disc 220 and the positioning plate 320 are both located at the assembling station, the fourth power assembly 250 can drive the lifting plate 240 to move towards the positioning plate 320 until the transition disc 220 is in butt joint with the rotor on the positioning plate 320, and the plurality of clamping grooves 221 of the transition disc 220 and the plurality of mounting holes 21 of the rotor 20 are arranged in a one-to-one correspondence manner.

Specifically, a second positioning block 222 is disposed on a bottom surface of the transition disc 220, and the second positioning block 222 can be matched with the rotor 20. The second positioning block 222 is similar to the positioning element 321 in structure, and the second positioning block 222 is provided with a key slot and can be matched with a boss on the rotor 20, so that the transition disc 220 is butted with the rotor 20. By abutting the transition disk 220 with the rotor 20, the plurality of card slots 221 can be in one-to-one correspondence with the plurality of mounting holes 21. Moreover, after the docking is completed, the relative position of the transition disc 220 and the rotor 20 can be kept fixed. Therefore, the insertion mechanism 100 has high accuracy when inserting the plurality of magnetic steels into the rotor 20.

Further, in the present embodiment, the adapter mechanism 200 further includes a floating member 260 and a positioning assembly 270, and the transition disk 220 is mounted to the lifting plate 240 via the floating member 260, so that the transition disk 220 has a floating amount along the circumferential direction of the transition disk 220.

Optionally, the floating member 260 is an end bearing, and the transition disk 220 is mounted on the lifting plate 240 via four end bearings. The face bearing has a large axial load capacity and is able to allow the transition disk 220 to rotate circumferentially within a small range, thereby creating a floating amount. Because machining errors are difficult to avoid, when the transition disc 220 is butted with the rotor, a fit clearance exists between the transition disc and the rotor. Therefore, even after the two are butted, it is not always ensured that the card slot 221 is completely aligned with the mounting hole 21 of the rotor 20. At this time, the transition disk 220 floats in the circumferential direction, so that the relative position of the transition disk 220 and the rotor 20 can be adjusted within a certain range, and the plurality of slots 221 and the plurality of mounting holes 21 are well aligned. In this way, the insertion mechanism 100 can more accurately transfer the magnetic steel on the transition disk 220 into the rotor 20.

The positioning assembly 270 has a locked state that secures the transition plate 220 to the lift plate 240. Specifically, the positioning assembly 270 includes a positioning cylinder 271 and a positioning pin 272, the positioning cylinder 271 is fixed to the transition plate 220, a moving end of the positioning cylinder is fixedly connected to the positioning pin 272, and the lifting plate 240 is provided with a positioning hole 241 capable of being matched with the positioning pin 272. When the magnetic steel is installed in the transition disc 220, the positioning cylinder 271 acts and drives the positioning pin 272 to be inserted into the positioning hole 241, so as to switch the positioning assembly 270 to the locking state. In this way, the transition disk 220 will remain stable and not float, thereby facilitating the loading of the magnetic steel.

When the transition disc 220 needs to be docked with the rotor 20, the positioning cylinder 271 acts and drives the positioning pin 272 to withdraw from the positioning hole 241, so that the positioning assembly 270 unlocks the transition disc 220. At this time, the transition disk 220 can float, so that the transition disk 220 can be smoothly butted with the rotor 20, and the clamping groove 221 and the mounting hole 21 are better aligned in the process of transferring the magnetic steel.

After the magnetic steels are all installed in the installation hole 21 of the rotor 20, the magnetic flux of each magnetic steel needs to be detected to judge whether the magnetic steel meets the technical requirements. Specifically, in this embodiment, the magnetic steel inserting device 10 further includes a magnetic flux detecting mechanism (not shown), and the magnetic flux detecting mechanism can detect the magnetic flux of the magnetic steel passing through the detection range. Optionally, the magnetic flux detection mechanism is disposed at the assembly station, and since the magnetic flux detection mechanism is disposed at the assembly station, when the magnetic steel is pushed into the rotor 20 by the inserting mechanism 100, the magnetic flux detection mechanism can immediately detect the magnetic flux, which is beneficial to saving time.

Referring to fig. 8 and 9, in another embodiment, the feeding mechanism 300 further includes a rotary driving member 340, and the rotary driving member 340 is mounted on the second moving plate 330 and can drive the positioning plate 320 to rotate.

Specifically, the rotary driving member 340 may be a motor, and the positioning plate 320 may be fixedly connected to the driving end of the rotary driving member 340. Furthermore, the positioning plate 320 is not fixed to the second moving plate 330, and thus can be rotated by the rotary driving member 340.

Further, the positioning plate 320 rotates to drive the plurality of magnetic steels installed in the rotor 20 to sequentially pass through the detection range of the magnetic flux detection mechanism. That is, the rotary driving member 340 operates to sequentially detect the plurality of magnetic steels in the rotor 20 by the magnetic flux detection mechanism, thereby significantly improving the detection efficiency.

Further, in the present embodiment, the feeding mechanism 300 further includes a mounting plate 350, a jacking driving member 360 and a vertical moving plate 370.

The mounting plate 350 is located on a side of the second moving plate 330 facing away from the positioning plate 320 and is fixedly connected to the second moving plate 330. Specifically, the lower side of the second moving plate 330 is connected to the mounting plate 350 by a link 380. The lift actuator 360, which may be a cylinder, is secured to the mounting plate 350. Obviously, the mounting plate 350 may be omitted, and the lift driving member 360 is directly and fixedly mounted to the second moving plate 330. The vertical moving plate 370 is located at a side of the second moving plate 330 facing away from the mounting plate 350, and the positioning plate 320 is located at a side of the vertical moving plate 370 facing away from the second moving plate 330. More specifically, the vertical moving plate 370 is vertically slidably coupled to the mounting plate 350 by a third guide 390, so that the vertical moving plate 370 can be elevated with respect to the surface of the second moving plate 330.

The vertical moving plate 370 is mounted at the driving end of the jacking driver 360 and can be lifted and lowered relative to the surface of the second moving plate 330 under the driving of the jacking driver 360. Also, the rotary driving member 340 is fixed to the vertical moving plate 370.

When all the magnetic steel is loaded into the rotor 20, the lifting driving member 360 will act and drive the vertical moving plate 370 to move upward, so that the vertical moving plate 370 and the positioning plate 320 are lifted from the surface of the second moving plate 330. Then, the rotary driving member 340 acts to drive the positioning plate 320 and the rotor 20 thereon to rotate, so that the magnetic steel in the rotor 20 sequentially passes through the detection range of the magnetic flux detection mechanism.

Referring to fig. 1 and fig. 10 again, in the present embodiment, the magnetic steel inserting apparatus 10 further includes a gripping mechanism 500, and the gripping mechanism 500 includes a gripper 510 and a transferring assembly 520.

The hand grip 510 can grip and release the magnetic steel, and the hand grip 510 is installed at the driving end of the transfer assembly 520. Move and carry subassembly 520 and can drive tongs 510 and remove to realize that the magnet steel transports. When the transition disc 220 is located at the feeding station, the transferring component 520 can drive the gripper 510 to move, so that the gripped magnetic steels are sequentially placed in the plurality of clamping grooves 221 of the transition disc 220.

Specifically, the transferring assembly 520 includes a first driving member 521, a second driving member 522, a third driving member 523 and a fourth driving member 524. The moving end of the first driving member 521 is fixedly connected with the second driving member 522, and the first driving member 521 acts to drive the second driving member 522 to move along the X direction; the moving end of the second driving element 522 is fixedly connected with the third driving element 523, and the second driving element 522 acts to drive the third driving element to move along the Y direction; the moving end of the third driving member 523 is fixedly connected to the fourth driving member 524, and the third driving member 523 moves to drive the fourth driving member 524 to move along the Z-axis direction; the moving end of the fourth driving member 524 is fixedly connected to the gripper 510, and the fourth driving member 524 operates to drive the gripper to rotate around the Z axis.

The first, second and third drivers 521, 522 and 523 may be configured by an air cylinder, a motor screw nut set, etc., and the fourth driver 524 may be a motor, a rotary air cylinder, etc. Under the driving of the transfer assembly 520, the hand grip 510 has four degrees of freedom, so that the magnetic steel can be more conveniently and accurately loaded into the transition disc 220. Obviously, the transfer unit 520 may be a robot.

Referring to fig. 11 and 12, in the present embodiment, the hand grip 510 includes a sleeve 511, a pushing drive 512, and a pushing rod 513.

The bushing 511 is generally hollow and cylindrical with a clamping channel 5111 for holding the magnetic steel. The magnetic steel can enter from the opening at one end of the clamping channel 5111 and is clamped. Specifically, the side wall of the boss 511 begins with a threaded hole 5112 for mounting the resilient plunger. When the magnetic steel is pushed into the clamping channel 5111, the elastic plunger can be extruded and deformed to tightly support the magnetic steel, so that the magnetic steel is prevented from falling off from the shaft sleeve 511, and the magnetic steel is grabbed.

The material pushing drive 512 may be a pneumatic cylinder. The push rod 513 is installed at the driving end of the pushing driving element 512 and extends into the shaft sleeve 511, and the push rod 513 can push the magnetic steel out of the clamping channel 5111 under the driving of the pushing driving element 512. When the gripper 510 needs to release the magnetic steel, the pushing driving element 512 acts and the pushing rod 513 pushes the magnetic steel out of the clamping channel 5111.

In the magnetic steel inserting device 10, a plurality of magnetic steels can be pre-loaded into the transition disc 220 at the loading station, and the rotor 20 to be assembled is pre-positioned on the positioning plate 320. After the transition disc 220 and the positioning plate 320 enter the assembly station, the first power assembly 110 drives the plurality of pressing rods 120 to press down, so that the plurality of magnetic steels on the transition disc 220 can be inserted into the plurality of mounting holes 21 of the rotor 20 at one time. Further, after magnetic steel is installed in the rotor 20, magnetic flux detection needs to be performed on the installed magnetic steel. During the magnetic flux detection, the transition plate 220 can be moved to the loading station under the driving of the second power assembly 210, and a plurality of magnetic steels are loaded into the transition plate 220 again to prepare for the next assembly.
