Detailed implementation manners

[0024] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0025] Referring to Figure 1 , an electronic product assembly device is disclosed in an embodiment of the present invention, which is used for assembling a permanent magnet rotor. The permanent magnet rotor includes a rotor core 10 and a permanent magnet 20. The electronic product assembly device of the embodiment of the present invention includes a base 1, a clamping device 2, a blanking device 3, a commutation device 4, a pushing device 5, and a dispensing device 6. The clamping device 2 is installed on the base 1, and the rotor core 10 can be clamped and positioned by the clamping device 2. A plurality of receiving grooves 101 are formed on the circumferential surface of the rotor core 10. One side of the receiving groove 101 penetrates the end surface of the rotor core 10, and the receiving groove 101 penetrates the end surface of the rotor core 10 facing away from the clamping device 2. The opening width of the receiving groove 101 is smaller than the bottom width of the receiving groove 101, so that the permanent magnet 20 can be installed in the receiving groove 101 and is not easily separated from the connection with the receiving groove 101. The plurality of receiving grooves 101 are evenly distributed along the circumferential direction of the rotor core 10. The adjacent two permanent magnets 20 distributed along the circumferential direction of the rotor core 10 are arranged alternately with N and S poles. That is, if the N pole of the permanent magnet 20 installed in one receiving groove 101 faces the bottom of the receiving groove 101, the magnetic pole direction of the permanent magnet 20 installed in another receiving groove 101 adjacent to the receiving groove 101 is opposite, and the S pole of the other permanent magnet 20 faces the bottom of the receiving groove 101. The blanking device 3 is installed on the base 1 and corresponds to the clamping device 2. A plurality of permanent magnets 20 are arranged in the blanking device 3 in the height direction. The permanent magnet 20 at the bottom of the blanking device 3 can slide horizontally along the blanking device 3 and move out of the blanking device 3. The commutation device 4 is located between the clamping device 2 and the blanking device 3 and is used to convert the magnetic poles of the permanent magnets 20. The commutation device 4 has a discharge port aligned with the uppermost receiving groove 101. The pushing device 5 is located on the side of the blanking device 3 away from the commutation device 4. The pushing device 5 can push the permanent magnet 20 at the bottom of the blanking device 3 and sequentially pass through the blanking device 3 and the commutation device 4 until the permanent magnet 20 passes through the discharge port and is embedded in the receiving groove 101. The dispensing device 6 is arranged on the base 1 and above the rotor core 10. The glue outlet head 64 of the dispensing device 6 is aligned with one receiving groove 101. A driving device 7 is also installed on the base 1. The driving device 7 is connected to the dispensing device 6. The driving device 7 can drive the dispensing device 6 to move vertically back and forth so that the glue outlet head 64 abuts against the receiving groove 101 to discharge glue.

[0026] Referring to Figure 1 , Figure 2 and Figure 3, the clamping device 2 includes a clamping frame 21, a first mounting disc 22, a second mounting disc 23, a clamping rod 24 and a clamping motor 25. The clamping frame 21 is fixedly mounted on the base 1. The first mounting disc 22 is disposed on the clamping frame 21. Specifically, the first mounting disc 22 is rotatably disposed on the clamping frame 21. A circular groove is formed in the clamping frame 21, and the first mounting disc 22 is rotatably mounted in the circular groove. Moreover, a positioning ring is fixed to the groove wall of the circular groove, and an annular groove cooperating with the positioning ring is formed in the circumferential surface of the first mounting disc 22. The first mounting disc 22 and the second mounting disc 23 are coaxially arranged, and the second mounting disc 23 is located on the side of the first mounting disc 22 close to the blanking device 3. Three sliding grooves 221 are formed in the side of the first mounting disc 22 close to the second mounting disc 23. The three sliding grooves 221 are uniformly distributed along the circumferential direction of the first mounting disc 22, and the extension line of the sliding groove 221 passes through the center of the first mounting disc 22. One end of the clamping rod 24 is slidably connected in the sliding groove 221, and the other end extends horizontally along the axial direction of the first mounting disc 22. The sliding groove 221 is a dovetail groove, and the end of the clamping rod 24 is a dovetail block cooperating with the dovetail groove. One clamping rod 24 is slidably connected in each sliding groove 221. The clamping motor 25 is fixedly mounted on the side of the first mounting disc 22 away from the second mounting disc 23, and the output shaft of the clamping motor 25 passes through the first mounting disc 22 and is fixedly connected to the center of the second mounting disc 23. Three arc-shaped grooves 231 are formed in the second mounting disc 23. The three arc-shaped grooves 231 are uniformly distributed along the circumferential direction of the second mounting disc 23, and one end of the arc-shaped groove 231 gradually bends from near the center of the second mounting disc 23 towards the direction close to the circumferential surface of the second mounting disc 23. The other end of the clamping rod 24 passes through the corresponding arc-shaped groove 231 and is slidably engaged with the arc-shaped groove 231. By starting the clamping motor 25 to rotate forward, the second mounting disc 23 can be driven to rotate, so that the clamping rod 24 slides along the arc-shaped groove 231, and the distance between the plurality of clamping rods 24 and the center of the first mounting disc 22 increases, so that the clamping rod 24 abuts against the inner wall of the rotor core 10, thereby fixing the rotor core 10. When the clamping motor 25 is driven to rotate in the reverse direction, the plurality of clamping rods 24 can slide towards the center of the first mounting disc 22 along the arc-shaped groove 231, and thus the clamping of the rotor core 10 can be released, facilitating the removal of the rotor core 10.

[0027] Refer to Figure 1 , Figure 2 and Figure 3, Further, when it is necessary to switch the receiving groove 101, a rotating mechanism 8 is installed on the clamping bracket 24, which can be used to drive the first mounting disk 22 to rotate, and then drive the rotor core 10 to rotate, so that the next receiving groove 101 can rotate to align with the dispensing device 6. The rotating mechanism 8 includes a toothed ring 81, a rotating frame 82, a rotating gear 83 and a rotating motor 84. The rotating frame 82 is fixedly installed on one side of the clamping bracket 21. The first mounting disk 22 extends towards the side close to the blanking device 3. The toothed ring 81 is fixedly installed on the circumferential surface of the first mounting disk 22. The rotating motor 84 is fixedly installed on the rotating frame 82. The rotating gear 83 is fixedly installed on the output shaft of the rotating motor 84, and the rotating gear 83 meshes with the toothed ring 81. By starting the rotation of the rotating motor 84, the toothed ring 81 can be driven to rotate by the rotating gear 83, and then the first mounting disk 22 can be driven to rotate, and then the rotor core 10 can be driven to rotate.

[0028] Refer to Figure 1 , Figure 4 and Figure 5, the blanking device 3 includes a material cylinder 31 and a spring piece 32. The material cylinder 31 is vertically arranged on the base 1, and the material cylinder 31 is detachably installed on the base 1. A plurality of permanent magnets 20 arranged in the height direction are provided in the material cylinder 31, and the magnetic pole directions of the plurality of permanent magnets 20 are the same. A first blanking port is provided on one side of the material cylinder 31. The permanent magnet 20 can be inserted into the material cylinder 31 from the first blanking port or can be installed from the top of the material cylinder 31. The first blanking port corresponds to the pushing device 5, and a second blanking port is provided on the other side of the material cylinder 31. The second blanking port corresponds to the commutation device 4. The permanent magnet 20 can slide along the first blanking port to the second blanking port. It can be understood that the placement direction of the permanent magnet 20 is the same as the extension direction of the receiving groove 101. Then, the permanent magnet 20 is pushed so that the permanent magnet 20 can smoothly insert into the receiving groove 101 from one end of the receiving groove 101 along the specified path until the permanent magnet 20 is completely embedded in the receiving groove 101. The spring piece 32 is arranged at the inner top of the material cylinder 31. The spring piece 32 is wavy. The upper end of the spring piece 32 is fixedly connected to the inner top wall of the material cylinder 31, and the lower end of the spring piece 32 abuts against the permanent magnet 20 located at the uppermost part of the material cylinder 31 so that the permanent magnet 20 has a downward movement tendency. Optionally, the top wall of the material cylinder 31 is detachably connected to the material cylinder 31, which is convenient for installing the spring piece 32 or for installing the permanent magnet 20 into the material cylinder 31. To improve the installation stability of the permanent magnet 20, a limiting member 33 is provided on the side of the material cylinder 31 close to the pushing device 5. The limiting member 33 is located above the first blanking port. The limiting member 33 includes a first fixing plate 331, a second fixing plate 332, a limiting rod 333, and a limiting block 334. The first fixing plate 331 is fixedly installed on the side of the material cylinder 31 close to the pushing device 5. The second fixing plate 332 is located below the first fixing plate 331. The limiting rod 333 is inserted into the first fixing plate 331 and is slidably matched with the first fixing plate 331. The limiting rod 333 is vertically arranged. The lower end of the limiting rod 333 is fixedly connected to the second fixing plate 332. Two limiting rods 333 are arranged at intervals along the length direction of the first fixing plate 331. A limiting spring 335 is sleeved on the limiting rod 333. The two ends of the limiting spring 335 are respectively fixedly connected to the first fixing plate 331 and the second fixing plate 332. The upper end of the limiting rod 333 passes through the first fixing plate 331 and is fixed with a limiting piece 336. The limiting block 334 is fixedly connected to the lower end surface of the second fixing plate 332. The lower end surface of the limiting block 334 is formed with an inclined surface, and the inclined surface inclines upward and away from the material cylinder 31. The pushing device 5 corresponds to the limiting block 334. Without the action of other external forces, the limiting spring 335 makes the limiting block 334 close the first blanking port, which can prevent the permanent magnet 20 from moving out.

[0029] Refer to Figure 1 , Figure 3 , Figure 5, the pusher device 5 includes a pusher rod 51 and a pusher brake 52. The pusher brake 52 is installed on the side of the barrel 31 away from the commutation device 4. The axial direction of the pusher rod 51 is consistent with the axial direction of the rotor core 10. The pusher rod 51 is connected to the pusher brake 52. One end of the pusher rod 51 abuts against the permanent magnet 20 and can pass through the blanking device 3 and the commutation device 4 to push the permanent magnet 20 into the receiving groove 101. The pusher brake 52 is used to drive the pusher rod 51 to reciprocate axially along the rotor core 10. The pusher brake 52 includes a pusher frame 521, a guide cylinder 522, a pusher motor 523, and a pusher gear 524. The pusher frame 521 is arranged on one side of the blanking device 3. The guide cylinder 522 is installed on the pusher frame 521. The guide cylinder 522 is coaxially arranged with the pusher rod 51. The pusher rod 51 passes through the guide cylinder 522 and is in sliding fit with the guide cylinder 522. The pusher motor 523 is arranged on the pusher frame 521. The output shaft of the pusher motor 523 passes through the pusher frame 521 and is provided with a pusher gear 524. The axial direction of the pusher gear 524 is perpendicular to the axial direction of the pusher rod 51. The lower surface of the pusher rod 51 is provided with a tooth groove 511 meshing with the pusher gear 524. A plurality of tooth grooves 511 are continuously arranged along the axial direction of the pusher rod 51. By starting the pusher motor 523 to rotate forward, the pusher gear 524 can be driven to rotate towards the blanking device 3, driving the pusher rod 51 to move towards the side close to the blanking device 3 along the guide cylinder 522. Further, the end of the pusher rod 51 abuts against the limit block 334. When the pusher rod 51 slides further, the limit block 334 can be pushed to slide upward against the elastic force of the limit spring 335, so that the pusher rod 51 passes through the first blanking port and abuts against the permanent magnet 20 located at the first blanking port. The pusher rod 51 pushes the permanent magnet 20 to pass through the second blanking port along the first blanking port.

[0030] Refer to Figure 1 , Figure 4 and Figure 6, the commutation device 4 includes a commutation frame 41, a commutation cylinder 42, and a commutation mechanism 43. The commutation frame 41 is arranged on the base 1 and is located between the blanking device 3 and the clamping device 2. The commutation cylinder 42 is rotatably connected to one side of the commutation frame 41 close to the blanking device 3. The axial direction of the commutation cylinder 42 is consistent with the axial direction of the rotor core 10. A material guiding port is arranged at the end of the commutation cylinder 42. An outlet is arranged on the commutation frame 41 corresponding to the receiving groove 101. The material guiding port is communicated with the outlet, and the material guiding port is aligned with the second blanking port of the blanking device 3. When part of the permanent magnet 20 is located in the second blanking port, the other part of the permanent magnet 20 can be inserted into the material guiding port. An installation groove for accommodating the permanent magnet 20 is formed in the commutation cylinder 42, and both ends of the installation groove are communicated with the material guiding port and the outlet respectively. When the permanent magnet 20 moves to the position where the commutation frame 41 is close to the clamping device 2, when part of the permanent magnet 20 is located at the outlet, the other part of the permanent magnet 20 is inserted into the receiving groove 101. The commutation mechanism 43 is arranged on the commutation frame 41 and is used to drive the commutation cylinder 42 to rotate 180°.

[0031] Referring to Figure 1 , Figure 4 and Figure 6 , it should be emphasized that the first blanking port, the second blanking port, the material guiding port, the outlet, and the receiving groove 101 located at the uppermost part of the rotor core 10 are all on the same horizontal plane, so that the permanent magnet 20 can sequentially pass through the second blanking port, the material guiding port, and the outlet from the first blanking port and move into the receiving groove 101 located at the uppermost part of the rotor core 10. Specifically, the distance between the material guiding port and the second blanking port is less than the length of the permanent magnet 20, and the distance between the outlet and the receiving groove 101 is less than the length of the permanent magnet 20, so that the permanent magnet 20 can be smoothly connected when sliding between the blanking device 3 and the commutation device 4, and the permanent magnet 20 can be smoothly connected when sliding between the commutation device 4 and the rotor core 10.

[0032] Referring to Figure 1 , Figure 6 , two groups of connected first guiding grooves 437 and second guiding grooves 438 are arranged on the circumferential surface of the commutation cylinder 42. The two groups of first guiding grooves 437 are symmetrically arranged about the axis of the commutation cylinder 42. The first guiding grooves 437 are arranged along the axial direction of the commutation cylinder 42. The second guiding grooves 438 are spiral grooves arranged along the circumferential surface of the commutation cylinder 42. The second guiding grooves 438 are centered on the axis of the commutation cylinder 42 and the surrounding angle is 180°. The commutation mechanism 43 includes: a commutation ring 434, a connecting column 436, and a commutation braking member. The commutation ring 434 is sleeved outside the commutation cylinder 42 and slides along the axial direction of the commutation cylinder 42. There are two connecting columns 436. One connecting column 436 is slidably connected in each group of first guiding grooves 437 and second guiding grooves 438. One end of the connecting column 436 is fixed to the commutation ring 434. The commutation braking member is connected to the commutation ring and is used to drive the commutation ring to reciprocally slide along the axial direction of the commutation cylinder.

[0033] The commutation braking member includes a bracket 431, a commutation lead screw 432, a commutation motor 433, and a sliding seat 435. The bracket 431 is disposed on one side of the commutation frame 41, and the bracket 431 is located below the commutation cylinder 42 and extends toward the side close to the blanking device 3. The commutation lead screw 432 is rotatably disposed on the bracket 431, and the axial direction of the commutation lead screw 432 is parallel to the axial direction of the commutation cylinder 42. The commutation motor 433 is disposed at one end of the bracket 431, and the output shaft of the commutation motor 433 is fixed to one end of the commutation lead screw 432. A sliding seat 435 is disposed on the lower surface of the commutation ring 434, and the commutation lead screw 432 passes through the sliding seat 435 and is threadedly connected to the sliding seat 435. By starting the commutation motor 433 to rotate forward, the commutation lead screw 432 can be driven to rotate, so that the sliding seat 435 moves along the commutation lead screw 432 toward the side close to the commutation frame 41, driving the commutation ring 434 to move. Since the connecting column 436 is fixed to the inner peripheral surface of the commutation ring 434, the connecting column 436 slides along the first guiding groove 437 into the second guiding groove 438. Due to the action of the two connecting columns 436, the commutation cylinder 42 rotates. When the connecting column 436 moves to the other end of the second guiding groove 438, the commutation cylinder 42 just rotates 180°, causing the magnetic poles of the permanent magnet 20 to flip, which is convenient for commuting the permanent magnet 20 when transporting the permanent magnet 20. When the commutation of the permanent magnet 20 is not required, the commutation motor 433 is turned off, so that the pushing device 5 directly pushes the permanent magnet 20 to move along the inside of the commutation cylinder 42 to the rotor core 10.

[0034] Refer to Figure 1 、 Figure 7 Figure, the dispensing device 6 includes a glue cylinder 61, a first piston 62, a support rod 63, and a glue outlet head 64. An installation frame 65 is fixed on the base 1 and on one side of the rotor core 10. The glue cylinder 61 is disposed on the installation frame 65 and above the rotor core 10. The first piston 62 is disposed in the glue cylinder 61 and slides along the height direction of the glue cylinder 61. A support rod 63 is fixed to the lower end of the first piston 62. The support rod 63 passes through the glue cylinder 61 and is fixed above the glue outlet head 64. The glue outlet head 64 can be a structure for pressing out glue, or can be connected to a glue supply pipe 74 to extrude glue through glue supply, and the specific form is not limited.

[0035] Refer to Figure 1 、 Figure 7, the driving device 7 includes a storage tank 71, a second piston 72, and a magnet 73. The storage tank 71 is located on the side of the blanking device 3 away from the commutation device 4. The storage tank 71 is arranged along the axial direction of the pushing rod 51. The storage tank 71 contains a liquid. Specifically, it can also be a gas, as long as piston movement can be achieved, and it is necessary to ensure that neither the liquid nor the gas corrodes the second piston 72. One end of the storage tank 71 away from the blanking device 3 is connected to the upper end of the rubber cylinder 61 through a pipeline 74. The second piston 72 is arranged in the storage tank 71 and slides along the length direction of the storage tank 71. A magnet 73 is arranged at one end of the pushing rod 51 away from the blanking device 3, and the magnet 73 is magnetically adsorbed to the second piston 72. By sliding the pushing rod 51 along the length direction of the storage tank 71, the magnet 73 can be driven to slide along the length direction of the storage tank 71, and then the second piston 72 can be driven to slide. When the pushing rod 51 slides towards the rotor core 10, the second piston 72 is driven to slide towards the rotor core 10, and then the liquid in the rubber cylinder 61 flows into the storage tank 71 along the pipeline 74, that is, the first piston 62 in the rubber cylinder 61 rises, driving the glue outlet head 64 away from the rotor core 10, so that the dispensing device 6 will not interfere with the installation of the permanent magnet 20. On the contrary, when the pushing rod 51 slides away from the rotor core 10, the glue outlet head 64 can be driven to approach the rotor core 10, facilitating dispensing. By coating glue in the receiving groove 101, the installation of the permanent magnet 20 can be strengthened.

[0036] The working principle of the embodiment of the present invention is as follows: The rotor core 10 is fixed by the clamping device 2, so that a receiving groove 101 is aligned with the glue outlet head 64. Then, the pushing rod 51 is driven to slide towards the side away from the feeding device 3. The pushing rod 51 drives the magnet 73 to slide, so that the second piston 72 slides along the storage tank 71 towards the direction away from the feeding device 3, thereby squeezing the liquid in the storage tank 71. The extruded liquid is squeezed into the glue cylinder 61 through the pipeline 74, so that the first piston 62 moves down along the glue cylinder 61, and then drives the glue outlet head 64 to correspond to the uppermost receiving groove 101. The first piston 62 drives the glue outlet head 64 to abut against the receiving groove 101, and squeezes the glue outlet head 64, so that the glue flows into the receiving groove 101. The pushing device 5 is used to push the permanent magnet 20 at the bottom of the barrel 31, so that the permanent magnet 20 passes through the barrel 31 and enters the commutation cylinder 42. If the previous permanent magnet 20 has not been commutated, the commutation cylinder 42 is driven to rotate 180° to exchange the magnetic poles of the permanent magnet 20. After the exchange, the pushing rod 51 is continuously driven, so that the pushing rod 51 pushes the permanent magnet 20 into the corresponding receiving groove 101, thereby completing the installation of one permanent magnet 20. When it is necessary to install the next permanent magnet 20, the clamping device 2 is driven to rotate, driving the rotor core 10 to rotate, so that another receiving groove 101 is aligned with the glue outlet head 64. It should be emphasized that when the pushing rod 51 slides towards the direction close to the rotor core 10, the pushing rod 51 drives the second piston 72 to slide towards the direction close to the feeding device 3, so that the liquid at the top of the glue cylinder 61 is sucked into the storage tank 71, and the first piston 62 slides upwards along the glue cylinder 61, driving the glue outlet head 64 to move upwards to avoid collision with the permanent magnet 20.

[0037] Referring to Figures 1 - 7 , the present invention also discloses an electronic product assembly method, which is assembled by using the electronic product assembly equipment in the above embodiment, including the following steps: S1, installing the rotor core on the clamping device, clamping the rotor core through the clamping device, and making an installation groove of the rotor core directly below the dispensing device; S2, installing a plurality of permanent magnets in the barrel, so that the plurality of permanent magnets are arranged along the height direction of the barrel; S3, starting the driving device to drive the dispensing device to descend and flow the glue into the uppermost receiving groove, starting the pushing device, so that the pushing rod sequentially passes through the feeding device and the commutation device until the permanent magnet passes through the material outlet and is embedded in the receiving groove; S4. When installing the next permanent magnet, the permanent magnet is pushed into the commutation device through the pushing device. After the commutation mechanism drives the commutation cylinder to rotate 180°, the pushing rod continues to slide towards the direction close to the rotor core to continue to push the permanent magnet through the material outlet and be embedded in the receiving groove.
