Detailed Implementation

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Reference Figures 1-11 The present invention provides an automatic magnet insertion device, including a feeding mechanism 300, a robotic arm 100 and a rotor moving platform;

[0045] The robotic arm 100 is used to insert the magnet supplied by the feeding mechanism 300 into the rotor 200 on the rotor moving platform.

[0046] The rotor moving platform includes a rotor support platform 150, a rotor rotating mechanism 340, and a fixed bracket 500; the rotor support platform 150 and the rotor rotating mechanism 340 are mounted on the fixed bracket 500.

[0047] A tooling plate 130 is provided on the rotor support platform 150, and a positioning pin 140 is provided on the tooling plate 130.

[0048] The tooling tray 130 is used to assemble the rotor 200, and the positioning pin 140 is used to fix the rotor 200 on the tooling tray 130.

[0049] The rotor rotation mechanism 340 is disposed at the lower end of the rotor support platform 150, and the rotor rotation mechanism 340 is connected to the tooling plate 130. The rotor rotation mechanism 340 is used to rotate the tooling plate 130.

[0050] Two pressure cap driving assemblies 800 are provided on the fixed bracket 500. The two pressure cap driving assemblies 800 are located on both sides of the tooling tray 130. One pressure cap driving assembly 800 is provided with a first pressure cap 900, and the other pressure cap driving assembly 800 is provided with a second pressure cap 110. The first pressure cap 900 and the second pressure cap 110 are spliced ​​together to form a protective pressure cap. The protective pressure cap is provided on the rotor 200, and an installation notch 120 is provided on the protective pressure cap. The robot arm 100 inserts the magnet into the slot of the rotor 200 through the installation notch 120.

[0051] In some embodiments, the feeding mechanism 300 of the automatic magnet insertion device is used to supply magnets; the robot arm 100 is used to insert the magnets at the feeding mechanism 300 into slots on the rotor 200 of the rotor moving platform.

[0052] The rotor support platform 150 is provided with a tooling plate 130. The rotor rotation mechanism 340 is connected to the tooling plate 130, enabling the tooling plate 130 to rotate. The rotation angle of the rotor rotation mechanism 340 can be changed depending on the different slots on the rotor 200. Generally, the rotor rotation mechanism 340 includes a motor, which is used to rotate the tooling plate 130.

[0053] Multiple positioning holes are provided on the tooling plate 130. Depending on the specifications of the rotor 200, the positioning pin 140 is inserted into different positioning holes, so that the tooling plate 130 can meet the fixing of rotors 200 of different specifications.

[0054] Similarly, other parts of the automatic magnet insertion device that need to be replaced according to the specifications of the rotor 200 are generally connected in a detachable manner. This makes it easier for the automatic magnet insertion device to use more suitable parts according to different usage requirements.

[0055] Both pressure cap drive assemblies 800 installed on the fixed bracket 500 are existing technologies. The first pressure cap 900 and the second pressure cap 110 are detachably connected to the pressure cap drive assembly 800 respectively. The first pressure cap 900 and the second pressure cap 110 of different specifications are adopted according to different rotors 200.

[0056] The first pressure cover 900 and the second pressure cover 110 form a protective pressure cover, which has an installation notch 120; the tooling plate 130 rotates to move different slots of the rotor 200 to the installation notch 120 in sequence; thus the robot arm 100 can insert the magnet into the slot from the installation notch 120.

[0057] Reference Figure 3 and Figure 5 In an optional embodiment, a lifting mechanism 600 is provided on the fixed bracket 500, and the rotor support platform 150 and the rotor rotation mechanism 340 are both provided on the lifting mechanism 600.

[0058] The lifting mechanism 600 moves the rotor 200 on the tooling plate 130 toward the protective cover.

[0059] Reference Figure 2 In an optional embodiment, the device platform 400 is further included, on which a movable guide rail assembly 700 is disposed, and the fixed bracket 500 is disposed on the movable guide rail assembly 700.

[0060] The device platform 400 is provided with a useful movable guide rail assembly 700, the fixed bracket 500 can move along the movable guide rail assembly 700, and a lifting mechanism 600 is provided on the fixed bracket 500, which can lift the rotor support platform 150.

[0061] The movable guide rail assembly 700 and the lifting mechanism 600 work together to enable the rotor support platform 150 to move up, down, back, and forth. In order to accurately determine the moving position of the rotor support platform 150, multiple sensors are installed on the device platform 400 to determine the position of the rotor support platform 150. The rotor support platform 150 moves to the installation position of the rotor 200 or to the position where the magnet is inserted, etc. The lifting position of the lifting mechanism 600 is also precisely controlled by sensors.

[0062] Reference Figure 6 and Figure 7 In an optional embodiment, the feeding mechanism 300 includes a magnetically shielded unloading guide assembly 160 and at least one magnetic steel hopper 170.

[0063] The magnet hopper 170 includes a plurality of magnet slots 190 arranged sequentially from top to bottom, and the magnet slots 190 are used to assemble magnets.

[0064] A material retrieval opening is provided on the magnetic steel hopper 170, and multiple magnetic steel grooves 190 can move sequentially into the material retrieval opening.

[0065] In an optional embodiment, the magnetic steel hopper 170 includes a lifting assembly;

[0066] The lifting assembly includes a lifting plate and a lifting device. Multiple magnetic steel grooves 190 are disposed on the lifting plate. The lifting device is connected to the lifting plate. The lifting device moves the magnetic steel grooves 190 sequentially to the material picking opening by raising and lowering the lifting plate.

[0067] Reference Figure 8 and Figure 9 In an optional embodiment, the magnet hopper 170 is provided with a pushing component and a picking component, the picking component being located at one end of the picking opening; the pushing component is used to move the magnet in the picking opening toward the picking component.

[0068] In an optional embodiment, the pushing assembly includes a rodless cylinder 180 and a pushing member 210. One end of the pushing member 210 is disposed on the rodless cylinder 180, and the other end extends into the material picking opening and abuts against the magnet in the material picking opening.

[0069] In an optional embodiment, the material handling assembly includes a material handling body 260, a lower material lifting assembly 220 is provided at the lower end of the material handling body 260, and a side material lifting assembly 230 is provided on the side of the material handling body 260.

[0070] The material receiving body 260 has a material receiving cavity, which is connected to the material receiving opening; the material receiving body 260 is provided with a top material through hole 240 and a discharge through hole 250 that are connected to the material receiving cavity;

[0071] The lower top plate 280 of the lower top material assembly 220 is inserted into the top material through hole 240, and the magnet in the material taking chamber is pushed out from the top material through hole 240.

[0072] The side top plate 270 of the side top material assembly 230 is inserted into the unloading through hole 250, and the magnetic shielding sheet in the material taking chamber is pushed out from the unloading through hole 250 and pushed into the magnetic shielding unloading guide assembly 160.

[0073] The feeding mechanism 300 includes a magnetically shielded unloading and guiding component 160 and a magnetic steel hopper 170. Generally, it includes two magnetic steel hoppers 170, and the magnetically shielded unloading and guiding component 160 is arranged between the two magnetic steel hoppers 170.

[0074] The magnetic steel hopper 170 includes multiple magnetic steel troughs 190, generally three magnetic steel troughs 190 are provided, multiple magnets are placed in the magnetic steel troughs 190, and there are magnetic isolation sheets between two adjacent magnets.

[0075] The lifting platform is equipped with multiple magnetic slots 190. In order to make the lifting platform rise and fall smoothly, a guide component is generally installed on the lifting platform to make the lifting platform rise and fall smoothly.

[0076] Multiple sensors are installed on the magnetic steel hopper 170, typically three sensors, each used to accurately determine a position. After the lifting device raises and lowers the lifting plate, when each magnetic steel groove 190 moves to the position of the material dispensing opening, it will trigger the sensor corresponding to that magnetic steel groove 190. This ensures that the lifting assembly can move multiple magnetic steel grooves 190 into the material dispensing opening in sequence.

[0077] In order to accurately determine whether there is a magnet in the magnet trough 190, that is, whether the magnet trough 190 is full of magnets or not, the position of the rodless cylinder 180 corresponds to a sensor; the rodless cylinder 180 causes the pusher 210 to abut against the magnet in the magnet trough 190, and makes the magnet tend to move towards the picking component in real time.

[0078] The magnet in the magnet slot 190 enters the material taking body 260 under the action of the rodless cylinder 180. The lower ejector plate of the lower ejector assembly 220 is inserted into the ejector through hole 240 and ejects the magnet in the material taking chamber from the material taking body 260.

[0079] Because there is a magnetic shielding sheet between the two magnets, the side top plate 270 of the side top assembly 230 pushes the magnetic shielding sheet adjacent to the magnet out of the unloading through hole 250 and into the magnetic shielding unloading guide assembly 160.

[0080] The magnetic shielding unloading and guiding assembly 160 includes an unloading pipe and a receiving box. After the magnetic shielding sheet enters the unloading pipe, it enters the receiving box; thus completing the collection of the magnetic shielding sheet.

[0081] The side top material assembly 230 and the bottom top material assembly 220 generally use cylinders, etc. The lifting device in this application can use cylinders or other methods. Generally, the commonly used existing drive mechanisms are all acceptable.

[0082] A magnetic pole detection and identification sensor is generally installed at the material handling body 260. This sensor detects the orientation of the magnetic poles of the magnet, so that the robot arm 100 can remove the magnet in a suitable manner.

[0083] Reference Figure 10 , Figure 11 and Figure 12 In an optional embodiment, the robotic arm 100 includes an assembly component and an insertion component. The assembly component includes an assembly body 310, on which an assembly hole 290 is provided.

[0084] The magnet ejected from the top material through hole 240 enters the assembly hole 290; a permanent magnet 320 is provided on the assembly body 310, and the permanent magnet 320 is used to fix the magnet in the assembly hole 290;

[0085] An insertion assembly is provided on the upper end of the assembly body 310. The insertion assembly includes an insertion device and an insertion plate 330. The insertion plate 330 is connected to the insertion device. The insertion device inserts the insertion plate 330 into the assembly hole 290, thereby disengaging the magnet from the assembly hole 290.

[0086] Based on the information fed back by the magnetic pole detection and identification sensor, the robot arm 100 rotates the assembly body 310 so that the magnet inserted into the assembly hole 290 can be magnetically attracted to the permanent magnet 320. This ensures that the magnet will not detach from the assembly hole 290 after the robot arm 100 moves.

[0087] Once the mounting hole 290 aligns with the slot on the rotor 200, the insertion device of the insertion assembly inserts the insertion plate 330 into the mounting hole 290, causing the magnet to be pushed out by the insertion plate 330 and enter the slot, thus completing the automatic insertion of the magnet of the rotor 200.

[0088] The insertion device is generally a cylinder; the insertion device inserts the insertion plate 330 into the assembly hole 290, so that the assembly hole 290 is pushed out from the other end and enters the slot, and presses the magnet into place; after the slot of the rotor 200 is inserted into the magnet, by rotating the rotor 200, the slots without magnets are exposed from the installation notch 120.

[0089] The robotic arm 100 of the automatic magnet insertion device employs motion control, servo control for the rotor movement platform, and discrete control in conjunction with a protective cover, achieving integrated electromechanical intelligent control in collaboration with mechanical limit and positioning mechanisms. The protective cover exposes only one slot at a time, effectively preventing missed or incorrect insertions and preventing damage caused by inserted magnets being ejected due to repulsive forces.

[0090] Reference Figure 6 and Figure 7 In an optional embodiment, the feeding mechanism 300 includes two magnetic steel hoppers 170, which are disposed on both sides of the magnetically shielded unloading assembly 160.

[0091] The robotic arm 100 of the automatic magnet insertion device provided by this invention can insert the magnets provided by the feeding mechanism 300 into the slots on the rotor 200. To prevent the magnets from popping out during the pressing process, a protective cover is provided on the rotor 200. The robotic arm 100 assembles the magnets into the slots of the rotor 200 through the mounting notch 120. After the slot is inserted into the magnet, the tooling plate 130 rotates, rotating the insertion with the assembled magnet under the protective cover, thus preventing the magnet from popping out of the slot. The tooling plate 130 rotates in one direction, so that the slots on the rotor 200 are inserted into the magnets one by one. Compared with manual assembly, this improves work efficiency and avoids problems such as misinsertion, omissions, and incomplete pressing.

[0092] To adapt to the different types of rotors 200, the movement trajectory and posture of the control robot 100, as well as the height and rotation angle of the rotor moving platform, are adjusted to meet the automatic magnet insertion requirements of various embedded permanent magnet motors, such as radial, tangential, and V-type tangential types.

[0093] The automatic magnet insertion device has an electrical control cabinet, which contains a PLC and a cantilever control box assembly to achieve a combination of motion control and discrete control. It collects electrical feedback information through signal sensing devices, and coordinates with communication methods such as IO interaction and socket and Modbus to achieve one-click automated command operation.

[0094] This automatic magnet insertion device enables the automatic insertion of magnets into embedded permanent magnet motors, meeting the high-quality and high-efficiency requirements of permanent magnet motor manufacturing. The adoption of an electromechanical integrated control system for automatic magnet insertion, along with the addition of a press-fit protective cap and a dual-hopper feeding design, effectively improves motor production efficiency, reduces potential quality issues, and ensures motor production safety.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
