[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] It should be noted that when a component is referred to as being “fixed to” or “disposed on” another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as being “connected to” another component, it can be directly or indirectly connected to the other component.

[0050] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features.

The chute body 1, drive device 3, core shell feeding device 5, turning device 6, magnet feeding device 8, pole shoe feeding device 9 and punching cylinder 10 are all installed on the top of the cabinet 12. The cabinet 12 is equipped with a compressor, a power supply, etc. The compressor is used to supply air to the cylinder, and the power supply is used to power the electrical equipment.

[0053] The working principle and beneficial technical effects of the above technical solution are as follows: the core shell 300 is placed on the positioning seat 4 through the core shell feeding device 5, and then the magnet 100 is installed in the flip block 7 through the magnet feeding device 8, and then a pole shoe 200 is installed at one end of the magnet 100 through the pole shoe feeding device 9, and then the flip block 7 is driven to rotate one hundred and eighty degrees by the flip device 6. After that, the driving device 3 drives the slide 2 to move along the slide trough body 1 to the bottom of the flip device 6, and then a pole shoe 200 is installed at the other end of the magnet 100 in the flip block 7, and pressed into the core shell 300 below. The linear motor 3 drives the slide 2 to return to the initial position, and then after loading a magnet and two pole shoes, the driving device 3 drives the slide 2 to move to the bottom of the punch head 11, starts the punching cylinder 10, and punches the upper end of the core shell 300. The package is completed after the port is bent inward. The packaged core is as shown Figure 21 As shown in the figure, the reciprocating movement of the slide 2 and the flipping of the flip block 7 install pole shoes at both ends of the magnet, which are then installed into the core shell. The punching cylinder then drives the punching head 11 for packaging, thus realizing the automatic assembly of the core and improving the assembly efficiency and quality.

[0054] In one embodiment, Figure 2-3 As shown, the driving device 3 includes: a power box 301, a screw 302 and a first rotating shaft 303. The power box 301 is provided at one end of the chute body 1, and the screw 302 is provided in the chute body 1. The screw 302 passes through the slide 2 and is threadedly connected to the slide 2. One end of the screw 302 is rotatably connected to the inner wall of the chute body 1, and the other end of the screw 302 is connected to one end of the first rotating shaft 303. The other end of the first rotating shaft 303 passes through the side wall of the chute body 1 and extends into the power box 301 and is coaxially connected to the first sprocket 304. The first rotating shaft 303 is rotatably connected to the side wall of the chute body 1. A first motor 305 is provided on the outer wall of the power box 301. The output shaft of the first motor 305 extends into the power box 301 and is coaxially connected to one end of the second sprocket 306. The first sprocket 304 and the second sprocket 306 are connected by a chain 307.

[0055] The working principle and beneficial technical effects of the above technical solution are as follows: start the first motor 305 to drive the second sprocket 306 to rotate, and drive the first sprocket 304 to rotate through the transmission of the chain 307. After the transmission is decelerated, the first sprocket 304 drives the screw 302 to rotate, and the screw 302 and the slide 2 are threadedly transmitted, so that the slide 2 moves back and forth along the slide trough body 1, and the slide 2 drives the positioning seat 4 to move to the desired position.

[0056] In one embodiment, Figure 4-7As shown, the magnetic core shell feeding device 5 includes: a first spiral vibrating feeder 501, a first spiral feeding rail 502 and a first screening rail 503. Two first spiral vibrating feeders 501 are arranged at intervals on the right side of the slide chute body 1. The first spiral feeding rail 502 is arranged in the first spiral vibrating feeder 501. The first spiral feeding rail 502 can vibrate and transport the magnetic core shell. The first screening rail 503 is arranged below the discharge end of the first spiral feeding rail 502. The small head end of the magnetic core shell can slide on the first screening rail 503. The discharge end of the first screening rail 503 is connected to one end of the linear feeding rail 504, and the other end of the linear feeding rail 504 extends out of the first spiral vibrating feeder 501.

[0057] The working principle and beneficial technical effects of the above technical solution are as follows: a lot of magnetic core shells 300 are loaded into the first spiral vibrating feeder 501, and through high-frequency vibration, a plurality of magnetic core shells 300 are spirally raised along the first spiral feeding track 502. When they move to the discharge end of the first spiral feeding track 502, the magnetic core shells 300 are arranged in a horizontal direction and move forward in sequence. Under the action of gravity, the magnetic core shells 300 fall downward. When the small end of the magnetic core shell 300 is at the right end, after the magnetic core shell 300 falls, the small end of the magnetic core shell can be stuck in the first The core shell 300 is placed in the groove of the screening rail 503, and then continues to move forward to the linear feed rail 504 with high-frequency vibration to feed the core sleeve; when the large end of the core shell 300 is at the right end, after the core shell falls, the large end of the core shell cannot be stuck in the groove of the first screening rail 503, and will fall to the bottom of the first spiral vibrating feeder 501 again under high-frequency vibration to circulate the feeding again. Only the core shell 300 with the large end facing upward can continue to move forward along the first screening rail 503 and finally be arranged in a straight line along the linear feed rail 504. Because the core shells are finally arranged in a row through continuous cyclic screening, and the large end tubes of the core shell 300 are facing upward, the assembly efficiency of the core sleeve is improved.

[0058] In one embodiment, Figure 4-9As shown, the linear feed rail 504 is connected to the upper end of the first bracket 505, and a first horizontal fixed plate 506 is provided above the two linear feed rails 504.

The lower end of the fourth cylinder 519 is connected to the upper end of the fixed rod 520 through a vertical plate 524, and the lower end of the sliding block 522 is connected to the clamping block 525. The two clamping blocks 525 are provided with an arc-shaped slot 526 on the opposite side.

[0060] The working principle and beneficial technical effects of the above technical solution are as follows: the first spiral vibrating feeder 501 can transport the magnetic core shells 300 stored inside to the linear feeding rail 504 through vibration screening, and the fourth cylinder 519 drives the two connecting rods 523 to swing away from or closer to each other, driving the two clamping blocks 525 to move away from or closer to clamp or release the magnetic core shells 300. The two clamping blocks 525 first move vertically downward to clamp the magnetic core shells 300, then move vertically upward, move toward the slide 2, and then move vertically downward. After placing the magnetic core shells 300 on the positioning seat 4, the magnetic core shells are released, and then they are lifted vertically upward and returned to the initial position, continuously circulating the movement to feed the magnetic core shells.

[0064] The working principle and beneficial technical effects of the above technical solution are as follows: the ninth cylinder 816 drives the push rod 817 to reciprocate, which can push the magnet 100 in the material tube 815 to the bottom of the first suction nozzle 810, and the sixth cylinder 805 drives the first suction nozzle 810 to move downward and contact with the magnet 100, and the eighth cylinder 811 is started to drive the vacuum plug in the first suction nozzle 810 to move upward, thereby generating negative pressure to suck and fix the magnet 100, and then the sixth cylinder 805 drives the first suction nozzle 810 to lift up, and then After that, the seventh cylinder 806 drives the first suction nozzle 810 to move toward the flip block 7. After moving to the desired position, the sixth cylinder 805 drives the first suction nozzle 810 to move downward, pressing the magnet 100 into the flip block 7. After that, the eighth cylinder 811 drives the vacuum plug in the suction nozzle 10 to move downward. After there is no negative pressure, the magnet 100 is separated from the first suction nozzle 810. After that, the sixth cylinder 805 drives the first suction nozzle 810 to move upward, and the seventh cylinder 806 drives the first suction nozzle 810 back to its initial position. Through the cooperation of each cylinder, the cylindrical magnets stacked in the material tube are accurately transported to the flip block. The suction nozzles continuously move in a cycle to load the materials, which improves the loading efficiency of the magnets.

[0065] In one embodiment, Figure 16-19As shown, the pole shoe feeding device 9 includes: a second spiral vibrating feeder 901, a second spiral feeding rail 902, a second screening rail 903 and a linear guide rail 904. The second spiral vibrating feeder 901 is provided on the right side of the flipping device 6. The second spiral feeding rail 902 is provided inside the second spiral vibrating feeder 901. The second spiral feeding rail 902 can vibrate and transport the pole shoe. The discharge end of the second spiral feeding rail 902 is connected to one end of the second screening rail 903. The large diameter end of the pole shoe can slide along the second screening rail 903. The rail groove depth of the second screening rail 903 is less than the thickness of the pole shoe, so that the pole shoe that does not conform to the orientation falls from the screening rail. The angle between the rail surface of the second screening rail 903 and the horizontal plane first gradually increases and then gradually decreases. The inclined rail surface makes it easier for the pole shoe that cannot be stuck on the screening rail 3 to fall under the action of gravity, thereby improving the screening efficiency. The other end of the second screening rail 903 is connected to one end of the linear guide rail 904, and the other end of the linear guide rail 904 extends out of the second spiral vibrating feeder 901.

[0066] The working principle and beneficial technical effects of the above technical solution are as follows: under high-frequency vibration, the pole shoe 200 moves upward along the second spiral feeding rail 902 in a spiral. When it moves to the second screening rail 903, the pole shoe 200 with the large diameter end facing downward is stuck in the second screening rail 903 and continues to move. However, the pole shoe 200 with the large diameter end facing upward cannot be stuck in the rail groove of the second screening rail 903 because its thickness is greater than the depth of the rail groove of the second screening rail 903 and its side wall is curved. Therefore, under the action of vibration and gravity, it falls to the second spiral vibrating feeder 901. Finally, the pole shoe 200 with the large diameter end facing downward can pass through the second screening rail 903 and be arranged in a straight line along the linear guide 904 for feeding. Through the continuous vibration of the spiral vibrating disk and the cyclic screening of the second screening rail, the pole shoes can be arranged in sequence for feeding with the large diameter end facing downward, thereby improving the feeding efficiency of the pole shoes.

[0067] In one embodiment, Figure 16-19As shown, the linear guide 904 is connected to the upper end of the second bracket 905, a second suction nozzle 906 is provided above the linear guide 904, a tenth cylinder 907 is provided above the second suction nozzle 906, the output end of the tenth cylinder 907 extends into the second suction nozzle 906 and is connected to the suction plug, the second suction nozzle 906 is connected to one end of the horizontal plate 908, the other end of the horizontal plate 908 is connected to the bottom end of the sixth slider 909, and the sixth slider 909 can slide on the sixth slide rail 910 in the horizontal direction. A horizontal eleventh cylinder 911 is provided at the top of the sixth slide rail 910, and the output end of the eleventh cylinder 911 is connected to the top of the sixth slider 909. A second vertical plate 912 is provided on one side of the linear guide rail 904, and a twelfth cylinder 913 is provided on the upper end of the second vertical plate 912. The output end of the twelfth cylinder 913 is downward and connected to the eleventh cylinder 911. A seventh slider 914 is slidably connected to the second vertical plate 912, and the seventh slider 914 is connected to the sixth slide rail 910.

[0068] The working principle and beneficial technical effects of the above technical solution are as follows: the linear guide 904 sends the pole shoe 200 to the bottom of the second suction nozzle 906, and the twelfth cylinder 913 drives the second suction nozzle 906 to move downward. When it contacts the pole shoe 200, the tenth cylinder 907 is started to suck the pole shoe. Then, the twelfth cylinder 913 drives the second suction nozzle 906 to move upward. After that, the eleventh cylinder 911 drives the second suction nozzle 906 to move left to the top of the flip block 7. The twelfth cylinder 913 drives the second suction nozzle 906 to move downward to install the pole shoe into the flip block 7. The suction nozzle 10 releases the pole shoe, and the feeding of the pole shoe is completed, thereby improving the feeding efficiency of the pole shoe.

[0070] Step 1: Two clamping blocks 525 clamp the magnetic core housing 300 onto the positioning seat 4 of the slide 2;

[0071] Step 2: The first suction nozzle 810 sucks a magnet 100 and installs it in the flip block 7;

[0072] Step 3: The second suction nozzle 906 sucks a pole piece 200 and installs it on one end of the magnet 100. The first movable plate 608 moves downward. After the flip block 7 flips 180 degrees, the first movable plate 608 moves upward.

[0073] Step 4: The slide 2 moves to the bottom of the first movable plate 608 , and the second suction nozzle 906 sucks another pole shoe 200 and installs it on the other end of the magnet 100 , and then presses the magnet 100 and the two pole shoes 200 into the magnetic core housing 300 ;

[0074] Step 5: The slide 2 returns to its initial position, and steps 2, 3, and 4 are repeated to install another magnet 100 and two pole shoes 200 into the core housing 300 .

[0075] Step 6: The slide 2 moves to the bottom of the punching head 11 , and the punching head 11 punches the upper end of the magnetic core shell 300 to complete the packaging.
