[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] For example, see Figures 1 to 13 , an automatic feeding device for magnetic tiles based on permanent magnet synchronous servo motor production, comprising two mutually fixed support tables 1, two conveying rods 101 are rotatably installed at both ends between the two support tables 1, and the two conveying rods 101 are connected by a conveying chain 102, a No. 1 motor 4 is fixed on the support table 1, and the output shaft of the No. 1 motor 4 is coaxially fixed with one of the conveying rods 101; The support platform 1 is also fixed with a first support frame 2 and a second support frame 3, and further includes: A material box 10, wherein the material box 10 is supplied to the conveyor chain 102 through a material supply assembly installed on one side of the support platform 1, and a fastening assembly for clamping the motor magnetic shoe is installed on the material box 10; The magnetic tile group supply assembly is installed on the No. 1 support frame 2 and the No. 2 support frame 3. A group of magnetic tiles required for a single motor is placed in the material box 10 through the magnetic tile group supply assembly, and the magnetic tile group supply assembly also cooperates with the locking assembly when it is placed on the magnetic tile group.

[0033] In the embodiment of the present invention, when the No. 1 motor 4 is working, one of the conveying rollers 101 is driven to rotate through its conveying shaft, and the conveying chain 102 is conveyed when the conveying roller 101 rotates. The intermittent conveying of the conveying chain 102 is achieved by controlling the rotation of the output shaft of the No. 1 motor 4 and the number of start and stop turns; During the intermittent period of the conveying chain 102, the material box 10 is pushed onto the conveying chain 102 by the material feeding assembly, so that the material box 10 is conveyed by the conveying chain 102. When the material box 10 moves to the bottom of the No. 1 support frame 2, the magnetic tile group is placed in the material box 10 by the magnetic tile group feeding assembly, and at the same time, the magnetic tile group is limited to the material box 10 by the fastening assembly through the cooperation with the fastening assembly; Among them, the magnetic tile group refers to the number of magnetic tiles used in a single motor. For example, if a single motor uses sixteen magnetic tiles, then the magnetic tile group described in the present invention is sixteen. Of course, the number of magnetic tiles used in motors of different models is different, and the specific number of magnetic tile groups in the present invention is not limited; Secondly, when the material box 10 is conveyed to the output end of the conveyor chain 102 , the material box 10 is taken from the conveyor chain 102 by a robot arm of the assembly equipment.

[0034] A limit rail group is fixed equidistantly along the conveying direction on the conveying chain 102, the limit rail group includes two limit rails, and two sliders cooperating with the limit rails are fixed at the bottom of the material box 10; An electromagnetic pin shaft is fixed on one opposite side of the two limit rails, and the movable shaft of the electromagnetic pin shaft is plugged into the pin hole 1007 provided on the slider; The bottom of the material box 10 is provided with a material discharge chute.

[0035] In the embodiment of the present invention, after the material box 10 is pushed onto the conveying chain 102 by the material feeding assembly, after the material box 10 is on the conveying chain 102, the electromagnetic pin shaft works, so that the movable shaft of the electromagnetic pin shaft is inserted into the pin hole 1007, so that the position of the limiter 103 and the slider 1005 is limited, so that the position of the material box 10 will not change during transportation; The electromagnetic pin shaft mentioned above is a combination of an electromagnet and a pin shaft, and the pin shaft is pushed to move when the electromagnet is energized.

[0036] The feeding assembly includes a feeding guide rail 504 fixed to the side of the support platform 1 away from the other support platform 1, and a second transmission rod 5 is rotatably mounted at the bottom of the feeding guide rail 504, and a torsion spring is installed on the second transmission rod 5; A feeding piece 505 is coaxially fixed on the second transmission rod 5. The feeding piece 505 is arranged in a semicircle. A first roller 506 is rotatably mounted on one end of the feeding piece 505. The second transmission rod 5 is connected to the magnetic tile group supply assembly through a transmission assembly. The feed guide rail 504 includes two limit rails, which are fixed by a transverse plate, and limit members are installed on the two limit rails; A travel limit block 104 is fixed on the other support platform 1; The limiting member includes an inclined top slider 507 that penetrates through the two limiting rails on opposite sides and slides with them. A No. 1 spring 508 is sleeved on the inclined top slider 507. One end of the No. 1 spring 508 is fixed to the limiting rail, and the other end is fixed to the inclined top slider 507. When the front-end equipment supplies the material box 10 to the feeding guide rail 504, it will apply a thrust to the material box 10. In order to prevent the material box 10 from moving toward the conveying chain 102 when the conveying chain 102 moves, the two inclined top sliders 507 are used to prevent the material box 10 from moving toward the conveying chain 102. 07 limits the material box 10. When it needs to move toward the conveyor chain 102, the material box 10 is pushed. The material box 10 cooperates with the inclined surfaces of the two inclined top sliders 507 to drive the two inclined top sliders 507 to move in opposite directions to make way for the material box 10 to pass. When the two inclined top sliders 507 move in opposite directions, the No. 1 spring 508 is pulled up and the No. 1 spring 508 stores elastic potential energy. After the material box 10 passes, the elastic potential energy of the No. 1 spring 508 is released to drive the two inclined top sliders 507 to reset.

[0037] In the embodiment of the present invention, when the magnetic shoe group supply component is working, the transmission component drives the second transmission rod 5 to rotate, and when the second transmission rod 5 rotates, it drives the feeding piece 505 and the first roller 506 to rotate. The feeding piece 505 and the first roller 506 rotate to push the material box 10 on the feeding guide rail 504 onto the limiting piece 103. In order to avoid the misalignment between the pin hole 1007 at the bottom of the material box 10 and the electromagnetic pin shaft due to inertia, the material box 10 is stroke-limited by the stroke limiting block 104; The function of the No. 1 roller 506 is to reduce the friction between the feeding member 505 and the material box 10 when they are in contact, so as to increase the service life of the parts.

[0038] The feeding assembly includes a feeding guide rail 504 fixed to the side of the support platform 1 away from the other support platform 1, and a second transmission rod 5 is rotatably mounted at the bottom of the feeding guide rail 504, and a torsion spring is installed on the second transmission rod 5; A feeding piece 505 is coaxially fixed on the second transmission rod 5. The feeding piece 505 is arranged in a semicircle. A first roller 506 is rotatably mounted on one end of the feeding piece 505. The second transmission rod 5 is connected to the magnetic tile group supply assembly through a transmission assembly. The feed guide rail 504 includes two limit rails, which are fixed by a transverse plate, and limit members are installed on the two limit rails; A travel limit block 104 is fixed on the other support platform 1 .

[0039] In the embodiment of the present invention, when the magnetic shoe group supply component is working, the transmission component drives the second transmission rod 5 to rotate, and when the second transmission rod 5 rotates, it drives the feeding piece 505 and the first roller 506 to rotate. The feeding piece 505 and the first roller 506 rotate to push the material box 10 on the feeding guide rail 504 onto the limiting piece 103. In order to avoid the misalignment between the pin hole 1007 at the bottom of the material box 10 and the electromagnetic pin shaft due to inertia, the material box 10 is stroke-limited by the stroke limiting block 104; The function of the No. 1 roller 506 is to reduce the friction between the feeding member 505 and the material box 10 when they are in contact, so as to increase the service life of the parts.

[0040] The transmission assembly includes a gear 501 coaxially fixed to the second transmission rod 5; A rack plate 502 is vertically and slidably installed on one side of the No. 1 support frame 2, and the rack plate 502 is meshed with the gear 501. A follower pressure plate 503 is also provided on the No. 1 support frame 2, and the follower pressure plate 503 is connected to the magnetic tile group supply assembly, and the follower pressure plate 503 cooperates with the rack plate 502.

[0041] In the embodiment of the present invention, when the magnetic shoe group supply assembly is working, the follower pressure plate 503 is driven to descend vertically. When the follower pressure plate 503 descends to contact with the rack plate 502, it continues to descend to drive the rack plate 502 to descend vertically. When the rack plate 502 descends, it drives the gear 501 and the second transmission rod 5 to rotate through the engagement with the gear 501. When the second transmission rod 5 rotates, the torsion spring is pulled up / compressed, so that the torsion spring reserves a certain amount of elastic potential energy. When the follower pressure plate 503 rises, the elastic potential energy of the torsion spring is released to drive the second transmission rod 5 to rotate in the opposite direction, thereby driving the gear 501 to rotate in the opposite direction synchronously, and the gear 501 is meshed with the rack plate 502 to drive the rack plate 502 to rise and reset; Among them, the torsion spring in the present invention is a relatively mature existing technology and is not shown in the figure.

[0042] The locking assembly includes a pressing plate 1003 slidably mounted in the material box 10, a second guide rod 1001 is fixed to one side of the pressing plate 1003, the second guide rod 1001 passes through the material box 10, and a second spring 1002 is sleeved on the second guide rod 1001; Both sides of the material box 10 are provided with movable grooves 1006, in which a No. 2 transmission shaft 1004 is slidably installed, and a roller is conveyed and installed on the No. 2 transmission shaft 1004. The No. 2 transmission shaft 1004 and the roller cooperate with the magnetic shoe group supply component.

[0043] In the embodiment of the present invention, when the magnetic tile group supply assembly is working, the No. 2 transmission shaft 1004 and the pressure plate 1003 are driven to translate by cooperation with the No. 2 transmission shaft 1004 and the roller. When the pressure plate 1003 translates, the No. 2 spring 1002 is compressed, and the chamber in the material box 10 is used to place the magnetic tile group. At this time, the magnetic tile assembly is placed in the chamber on the side of the pressure plate 1003 away from the No. 2 spring 1002; When the magnetic tile group supply assembly is disengaged, the elastic potential energy of the second spring 1002 is released to drive the pressure plate 1003 to move toward the magnetic tile group to clamp the magnetic tile group; Secondly, since a discharge chute is provided at the bottom of the material box 10, the magnetic tiles will fall through the discharge chute if they are not clamped. By clamping them, even if the material box 10 is out of the limit position of the discharge chute by the limit piece 103, the magnetic tiles will not fall. Subsequent assembly can be carried out by pushing the magnetic tiles through the discharge chute one by one, and after a single magnetic tile is pushed out, the elastic potential energy of the No. 2 spring 1002 will push the pressure plate 1003 to move again to clamp the subsequent magnetic tiles.

[0044] The magnetic tile group supply assembly includes a loading assembly and a unloading assembly, the loading assembly is installed on the second support frame 3, and the unloading assembly is installed on the first support frame 2, and the loading assembly and the unloading assembly cooperate with each other; The loading assembly is used to carry the magnetic tiles and deliver them to the required position of the unloading assembly; The material unloading assembly is used to carry the magnetic tiles and place the magnetic tiles in the material box 10.

When the unloading component works, it carries the magnetic tile group down and cooperates with the fastening component at the same time.

[0046] The loading assembly comprises a support plate 301 fixed to the second support frame 3, the support plate 301 is fixed on both sides of the L-shaped plate 303; A feeding plate 302 is installed on the support plate 301, a guide groove is provided on the support plate 301, a limit block 309 is fixed at the bottom of the feeding plate 302, and the limit block 309 is slidably installed in the guide groove; A rectangular block 3012 is also vertically and slidably installed on the support plate 301, and the rectangular block 3012 cooperates with the limiting groove 308 provided on the feeding plate 302. A No. 1 transmission shaft 3011 is fixed on both sides of the rectangular block 3012, and the No. 1 transmission shaft 3011 cooperates with the U-shaped groove 3010 provided on the limiting block 309; Incomplete gears 306 are also rotatably mounted on both sides of the feeding plate 302, and the incomplete gears 306 cooperate with the racks 305 provided on the L-shaped plate 303.

When the incomplete gear 306 rotates, the toothed portion cooperates with the second rack to drive the rack portion 305, the feed plate 302, and the parts mounted on the feed plate 302 to move toward the rack portion 305. When the feed plate 302 moves to the end of the stroke, the toothed portion of the incomplete gear 306 just disengages from the second rack. When the feeding plate 302 moves, it also drives the two limit blocks 309 to follow the movement. When the feeding plate 302 moves to the end of the stroke, the U-shaped groove 3010 of the limit block 309 moves to the outside of the first transmission shaft 3011; After the incomplete gear 306 is disengaged from the No. 2 rack, it continues to rotate and mesh with the No. 1 rack, and drives the feed plate 302 to rise vertically through the meshing with the No. 1 rack. When the feed plate 302 rises, the No. 1 transmission shaft 3011 and the rectangular block 3012 are driven to rise through the limit block 309 and the U-shaped groove 3010. A multi-stage telescopic component is installed in the rectangular block 3012, so that when the feed plate 302 and the rectangular block 3012 rise synchronously, due to the existence of the multi-stage telescopic component, the rectangular block 3012 extends into the limit groove 308 to limit the rise of the feed plate 302; See also Figure 7 The present invention provides a multi-stage telescopic assembly, comprising a telescopic block b3 slidably mounted in a rectangular block 3012, first gears b1 are mounted inside and outside the rectangular block 3012, two first gears b1 are coaxially fixed through a transmission shaft, a second rack a2 meshing with the first gear b1 is fixed on the telescopic block b3, a second gear b2 (wide gear) meshing with the first gear b1 is rotatably mounted outside the rectangular block 3012, and a first rack a2 meshing with the second gear b2 is fixed on the feeding plate 302; When the rectangular block 3012 rises, it drives the other collar parts except the first rack a1 to rise. When rising, the second gear b2 rotates by meshing with the first rack a1, and drives the first gear b1 to rotate in the opposite direction by meshing with the first gear b1. When the first gear b1 rotates, it drives the telescopic block b3 to rise by meshing with the second rack b2. Of course, this embodiment is only one of the ways to achieve it. When the feeding plate 302 moves, it will carry the magnetic tile to move synchronously. The positioning groove on the feeding plate 302 is used to place the front equipment. Based on the above work description, the function is to transport the magnetic tile to the first support frame 2; A counterweight block 304 is also fixed to the rear end of the feeding plate 302 for maintaining balance during the ascent.

[0048] The blanking assembly includes two oblique plates 201, which are fixed by a top plate 7, and guide cylinders 702 are fixed on opposite sides of the two oblique plates 201. The guide cylinders 702 are slidably matched with a No. 1 guide rod 701 fixed on a No. 1 support frame 2, and a clamping assembly is installed on the top plate 7; The oblique plate 201 cooperates with the second transmission shaft 1004 and the roller, and the follower pressure plate 503 is fixed on one of the oblique plates 201; The clamping assembly includes two bidirectional screw rods 704 rotatably mounted on the bottom of the top plate 7, and threaded sleeves are sleeved at both ends of the two bidirectional screw rods 704 to match the threads thereof, and a clamping plate 703 is fixed at the bottom of the threaded sleeves; A transmission rod 705 is also rotatably mounted on one side of the top plate 7. The transmission rod 705 is connected to two bidirectional screw rods 704 through two bevel gear sets 706. A first ratchet 8 and a second ratchet 801 are fixed to both ends of the transmission rod 705. The first ratchet 8 and the second ratchet 801 have opposite teeth. A second ratchet plate 901 and a first ratchet plate 9 are fixed to opposite sides of the two No. 1 support frames 2, respectively. The second ratchet plate 901 and the first ratchet plate 9 are located in the movement paths of the first ratchet 8 and the second ratchet 801, and the ratchet directions of the first ratchet plate 9 and the second ratchet plate 901 are opposite.

[0049] In the embodiment of the present invention, an electric telescopic rod (not shown) is also installed on the No. 1 support frame 2. When the electric telescopic rod is working, it drives the top plate 7 and the two inclined plates 201 to rise / fall vertically, and the magnetic tile is transferred to the bottom of the top plate 7 through the loading assembly; When the top plate 7 and the oblique plate 201 descend, the transmission rod 705 is driven to rotate by the cooperation of the second ratchet wheel 801 and the first ratchet plate 9. When the transmission rod 705 rotates, the two bidirectional screws 704 are driven to rotate synchronously through the bevel gear set 706, so as to drive the two clamping plates 703 to move relative to each other through the threaded cooperation with the threaded sleeve, so as to clamp the magnetic tile group under the top plate 7. After the clamping is completed, the feeding assembly is reset; Then the top plate 7 and the inclined plate 201 continue to descend, at which time the magnetic tile group has been clamped and carried, and the material box 10 is directly below the top plate 7; As the inclined plate 201 descends, the pressing plate 1003 is driven to translate through the cooperation between the inclined surface of the inclined plate 201 and the second transmission shaft 1004 and the roller, and the cavity generated by the translation is used to accommodate the magnetic tile group; When the magnetic tile group enters the chamber, the top plate 7 and the inclined plate 201 rise. During the rise, the first ratchet wheel 8 and the second ratchet plate 901 cooperate to drive the transmission rod 705 to rotate in the opposite direction, and the corresponding two clamping plates 703 move in the opposite direction to release the clamping of the magnetic tile. At this time, the magnetic tile group is in the chamber; The cooperation between the No. 1 ratchet 8 and the No. 2 ratchet 801 and the No. 1 pawl plate 9 and the No. 2 pawl plate 901 is described in detail. When the No. 2 ratchet 801 descends, it cooperates with the No. 2 pawl plate 901 to drive the two clamping plates 703 to move relative to each other to clamp the magnetic tile group. When descending to the end of the stroke, the No. 1 ratchet 8 and the No. 2 pawl plate 901 do not have a transmission relationship, and thus do not release the clamping. When ascending, the No. 1 ratchet 8 cooperates with the No. 2 pawl plate 901 to drive the two clamping plates 703 to move in the opposite direction to release the clamping of the magnetic tile group, and then moves to the top, so as to realize the back-and-forth unloading by repeating the above movement; It should be noted that the first ratchet wheel 8 and the second ratchet wheel 801 and the first ratchet plate 9 and the second ratchet plate 901 are all applications of the prior art, which are mainly used as a single-way transmission and will not be elaborated in detail.
