[0034] The core loading machine of the present invention includes a frame 100, a tube transfer assembly 200 for loading and transferring cores, a receiving assembly 300, a core transfer assembly 400 for tilting the tube and transferring the cores in the tube into the receiving assembly 300, a fixture return device 500 for transferring fixtures, a core positioning and feeding assembly 600 for transferring the cores in the receiving assembly 300 onto the fixture return device 500, and an ear pressing and bending assembly 700 for pressing and bending the ears of the cores in the fixture.

[0035] The tube transfer assembly 200 is arranged on the frame 100. The core transfer assembly 400 is arranged on the movement track of the tube transfer assembly 200. The receiving assembly 300 is arranged on one side of the tube transfer assembly 200, and the receiving assembly 300 and the tube transfer assembly 200 can be movably docked. The fixture return device 500 is arranged outside the receiving assembly 300. The core positioning and feeding assembly 600 is arranged between the receiving assembly 300 and the fixture return device 500. The ear pressing and bending assembly 700 is installed on one side of the fixture return device 500.

[0036] Among them, the frame 100 plays a supporting role for each structure of the present invention. At the same time, the tube transfer assembly 200 can realize the cyclic feeding of the tubes. The tubes are used to accommodate the cores to be fed. When the present invention performs the feeding action on the cores, first, when the tube transfer assembly 200 moves to a position opposite to the core transfer assembly 400, the core transfer assembly 400 tilts the tube in the tube transfer assembly 200, so that the cores accommodated in the tube slide into the receiving assembly 300 due to the action of gravity. The receiving assembly 300 can slide on the frame 100, so that the receiving assembly 300 can perform the receiving action on cores of different models in the tube transfer assembly 200. Thereafter, the core positioning and feeding assembly 600 clamps and transfers the cores entering the receiving assembly 300 into the fixtures in the fixture return device 500. At this time, the cores move together with the fixture return device 500. Thus, when the fixture return device 500 moves to a position corresponding to the ear pressing and bending assembly 700, at this time, the ear pressing and bending assembly 700 presses and bends the ears on the cores, thus completing the working process of the entire invention.

[0037] Here, the ear is a part for electrically connecting with an external brush on the commutator arranged at the end of the core. At the same time, the fixture return device 500 includes two conveyor belts. The conveyor belt of the two conveyor belts close to the core positioning and feeding assembly 600 is used to transfer the fixtures, and the core positioning and feeding assembly 600 loads the cores into the fixtures on this conveyor belt. The other conveyor belt is used to return the empty trays, that is, the fixture return device improved in the present invention is mainly used to transfer the fixtures.

[0038] In this embodiment, the material tube transfer assembly 200 includes a material tube support 210, a sliding guide rail 220, a first material tube accommodating portion 230, a second material tube accommodating portion 240, and a conveyor belt device 250 for driving the first material tube accommodating portion 230 and the second material tube accommodating portion 240 to slide. The material tube support 210 is arranged on the frame 100, the sliding guide rail 220 is fixedly connected to the material tube support 210, the first material tube accommodating portion 230 and the second material tube accommodating portion 240 are respectively slidably connected to both ends of the sliding guide rail 220, and the conveyor belt device 250 is installed on the material tube support 210.

[0039] Among them, the first material tube accommodating portion 230 and the second material tube accommodating portion 240 are used to accommodate the material tubes. The first material tube accommodating portion 230 and the second material tube accommodating portion 240 are slidably connected to the sliding guide rail 220 to realize the transfer of materials.

[0040] In one embodiment, different models of iron cores are accommodated in both the first material tube accommodating portion 230 and the second material tube accommodating portion 240. Users can select to move the material tube in the first material tube accommodating portion 230 or the second material tube accommodating portion 240 to a position matching the iron core transfer assembly 400, so as to realize the feeding of different models of iron cores.

[0041] In another embodiment, a material tray filled with iron cores is accommodated in the first material tube accommodating portion 230. When the material tray is driven by the conveyor belt device 250 to be opposite to the position of the iron core transfer assembly 400, the iron core transfer assembly 400 transfers the iron cores in the material tray into the receiving assembly 300 until all the iron cores in the material tray are discharged. At this time, the conveyor belt device 250 continues to drive the empty material tray to move, so as to accommodate the empty material tray in the second material tube accommodating portion 240, which can realize the rational cyclic feeding of materials and improve the working efficiency.

[0042] At the same time, the conveyor belt device 250 is two conveyor belts arranged side by side. The conveyor belts drive the material tubes in the first material tube accommodating portion 230 and the second material tube accommodating portion 240 to move on the conveyor belts, so as to realize the transfer of the material tubes.

[0043] In this embodiment, two relatively arranged material tube transfer notches 211 are formed on the material tube support 210.

[0044] Among them, the position of the material tube transfer notch 211 matches the position of the iron core transfer assembly 400, so that the iron core transfer assembly 400 can normally transfer the material tubes in the material transfer assembly through the material tube transfer notch 211.

[0045] In this embodiment, the material receiving assembly 300 includes a material receiving slide 310 and a material receiving driving device 320 for driving the reciprocating movement of the material receiving slide 310. The material receiving driving device 320 is fixedly connected to the frame 100, the material receiving slide 310 is slidably connected to the material receiving driving device 320, and a plurality of material receiving grooves 311 are formed in the material receiving slide 310. The material receiving grooves 311 communicate with the trays in the iron core transfer assembly 400.

[0046] Among them, the material receiving driving device 320 drives the reciprocating movement of the material receiving slide 310, so that the material receiving grooves 311 on the material receiving slide 310 communicate with the trays in the iron core transfer assembly 400, so that the iron cores in the material transfer assembly can enter the material receiving grooves 311 more smoothly.

[0047] At the same time, the number of the material receiving grooves 311 is multiple, and different material receiving grooves 311 can be used for discharging iron cores of different models.

[0048] Furthermore, the material receiving driving device 320 is specifically a driving mode of a motor plus a lead screw, that is, the motor drives the lead screw to rotate, and then the lead screw drives the material receiving slide 310 to move.

[0049] In this embodiment, one end of the material receiving groove 311 close to the iron core transfer assembly 400 is of an inclined structure.

[0050] Among them, the material receiving groove 311 with an inclined upper end enables the iron core to slide down naturally under the action of gravity after entering the material receiving groove 311. At the same time, it can play a role in buffering and protecting the iron core, so that the iron core is smoothly conveyed to the bottom end of the material receiving groove 311, and thus can indirectly protect the iron core.

[0051] In this embodiment, the iron core transfer assembly 400 includes a jacking driving device 410, a support seat 420, a first clamping part 430, a first clamping cylinder 440 for driving the lifting of the first clamping part 430, a second clamping part 450, a second clamping cylinder 460 for driving the lifting of the second clamping part 450, and a spring member 470 for keeping the support seat 420 perpendicular to the frame 100. The jacking driving device 410 is arranged on one side of the material pipe transfer assembly 200. The support seat 420 is rotatably connected to the side wall of the material pipe transfer assembly 200. The first clamping cylinder 440 is installed at the upper end of the support seat 420. The second clamping cylinder 460 is installed at the lower end of the support seat 420. The first clamping part 430 and the second clamping part 450 are relatively slidably installed on the side wall of the support seat 420. One end of the spring member 470 is fixedly connected to the support seat 420, and the other end of the spring member 470 is fixedly connected to the material pipe transfer assembly 200.

[0052] Among them, when the iron core transfer component 400 in the present invention needs to transfer the iron core in the material tube, first, the first clamping part 430 and the second clamping part 450 on the support seat 420 respectively clamp and fix the material tube entering the first clamping part 430 and the second clamping part 450 under the drive of the first clamping cylinder 440 and the second clamping cylinder 460. At this time, the lifting drive device 410 jacks up the other end of the material tube, so that the iron core in the material tube enters the receiving component 300 under the action of gravity through the support seat 420.

[0053] Meanwhile, when the support seat 420 moves upward at one end of the material tube pushed by the lifting drive device 410, the first clamping part 430 and the second clamping part 450 clamp the other end of the material tube. Therefore, the support seat 420 tilts under the cooperation of the material tube and the lifting drive device 410. At this time, the spring part 470 deforms. When the iron core in the material tube is completely discharged, the lifting drive device 410 drives the empty material tray to move downward, and the support seat 420 returns to the initial state under the action of the elastic part and the lifting drive device 410, that is, the spring part 470 can play a certain buffering effect on the support seat 420.

[0054] Furthermore, the lifting drive device 410 can be a driving mode of a motor plus a lead screw. The motor drives the lead screw to rotate, so that the lead screw drives the external connecting plate to jack up or lower one end of the material tray.

[0055] In this embodiment, an iron core transfer hole 421 for the iron core to pass through is formed on the support seat 420, and the iron core transfer hole 421 communicates with the material tube in the material tube transfer component 200.

[0056] In this embodiment, the iron core positioning and feeding component 600 includes a feeding support 610, a vertical feeding drive device 620, a horizontal feeding drive device 630, a horizontal connecting piece 640, an iron core turning drive motor 650, a feeding jaw cylinder 660, and an angle detection sensor 670 for detecting the orientation of the iron core in the feeding jaw cylinder 660. The feeding support 610 is fixedly connected to the frame 100. The vertical feeding drive device 620 is fixedly connected to one end of the feeding support 610. The horizontal feeding drive device 630 is slidably connected to the side wall of the vertical feeding drive device 620. The horizontal connecting piece 640 is fixedly connected to the output end of the horizontal feeding drive device 630. The iron core turning drive motor 650 is fixedly connected to the horizontal connecting piece 640. The output shaft of the iron core turning drive motor 650 is fixedly connected to the feeding jaw cylinder 660. The angle detection sensor 670 faces the feeding jaw cylinder 660.

[0057] Among them, the feeding support 610 plays a role in supporting each part and structure of the iron core positioning and feeding component 600.

[0058] Meanwhile, the vertical feeding drive device 620 and the horizontal feeding drive device 630 cooperate with each other to enable the two-way position transformation of the horizontal connecting member 640 in the horizontal and vertical directions; specifically, the horizontal feeding drive device 630 reciprocates vertically on the vertical feeding drive device 620, so as to realize the position adjustment of the iron core positioning and feeding assembly 600 in the vertical direction. Moreover, the horizontal feeding drive device 630 can drive the horizontal connecting member 640 to make a position adjustment in the vertical direction, so that the horizontal connecting member 640 can achieve multi-directional changes in the horizontal and vertical directions. The horizontal connecting member 640 drives the iron core turning drive motor 650 and the feeding jaw cylinder 660 to move together, so that the feeding jaw cylinder 660 can transfer the iron core in the receiving assembly 300 to the fixture in the fixture return device 500.

[0059] Furthermore, the angle detection sensor 670 detects the angle of the iron core on the feeding jaw cylinder 660. When it is detected that the orientation of the iron core does not match the fixture in the fixture return device 500, the iron core turning drive motor 650 enters the working state, thereby driving the feeding jaw cylinder 660 to rotate, so that the feeding jaw cylinder 660 drives the iron core to be transferred to the correct position.

[0060] Even further, the vertical feeding drive device 620 in the iron core positioning and feeding assembly 600 can adopt a driving mode of a motor plus a lead screw. The lead screw drives the horizontal feeding drive device 630 to realize the position transformation in the vertical direction, while the horizontal feeding drive device 630 can be driven by a cylinder, and the output end of the cylinder drives the horizontal connecting member 640 to make a reciprocating motion.

[0061] The ear pressing component 700 includes an ear pressing bracket 710, an ear pressing workbench 720, an ear pressing vertical drive device 730 for driving the ear pressing workbench 720 to reciprocate vertically, an ear pressing drive cylinder 740, a connecting member 750, a plurality of linkage rods 760, a plurality of clamping jaws 770, a protection spring 780, and an iron core accommodating portion 790. The ear pressing vertical drive device 730 is installed on the ear pressing bracket 710. The ear pressing drive cylinder 740 is installed on the upper side of the ear pressing workbench 720. The connecting member 750 is fixedly connected to the output shaft of the ear pressing drive cylinder 740. One end of the plurality of linkage rods 760 is movably connected to the connecting member 750, and the other end of the linkage rod 760 is movably connected to the plurality of clamping jaws 770. The protection spring 780 is installed between the connecting member 750 and the iron core accommodating portion 790. The linkage rod 760 drives the plurality of clamping jaws 770 to reciprocate radially along the lower surface of the ear pressing workbench 720 on the ear pressing workbench 720.

[0062] Among them, the ear pressing bracket 710 is used to support each structure in the ear pressing component 700. At the same time, the ear pressing vertical driving device 730 drives the ear pressing workbench 720 to reciprocate in the vertical direction. When the ear pressing workbench 720 abuts against the upper end of the iron core on the fixture in the fixture return device 500 driven by the ear pressing vertical driving device 730, first, the upper end of the iron core is placed in the iron core accommodating portion 790, and the iron core accommodating portion 790 plays a role in fixing the iron core. Then, the ear pressing driving cylinder 740 enters the working state, so that the output shaft of the ear pressing driving cylinder 740 contracts, driving the connecting member 750 to move together with the output end of the ear pressing driving cylinder 740. The connecting member 750 drives the linkage rod 760 to rotate, so that the other end of the linkage rod 760 drives a plurality of clamping jaws 770 to move towards the position close to the axis of the ear pressing workbench 720, so that the plurality of clamping jaws 770 press against the ears on the commutator of the iron core;

[0063] Specifically, the linkage rod 760 has an L-shaped structure, so that the clamping jaws 770 can move together with the movement of the linkage rod 760, thereby realizing the pressing action on the ears on the commutator at the upper end of the iron core.
