[0029] like Figure 1 and Figure 2 As shown: In this embodiment, the blanking assembly 5 includes a first fixed plate 501 and a second fixed plate 502, a blanking rod 503 is arranged between the first fixed plate 501 and the second fixed plate 502, and a through hole 504 is opened on the blanking rod 503 passing through the upper and lower sides, and the bottom end of the through hole 504 is connected to the transverse groove 7.

[0030] The magnets assembled in this way are placed in the through hole 504 on the drop rod 503. Since the size of the through hole 504 is fixed, larger magnets cannot be installed and will be separated out. At this time, the magnets at the bottom will fall into the horizontal groove 7 due to gravity.

[0031] like Figure 2 and Figure 3 As shown: In this embodiment, the top end of the blanking rod 503 is located outside the first fixed plate 501, the cross section of the through hole 504 is a fan-shaped structure, and the front side of the blanking rod 503 is provided with a first through seam 505 connected to the through hole 504.

[0032] When the magnet in the through hole 504 is stuck in this way, the thin sheet can be inserted into the first through slit 505 to move it downward, thereby avoiding the phenomenon of being stuck.

[0033] like Figure 1 and Figure 2 As shown: In this embodiment, the up and down adjustment component 4 includes a first cylinder 401 fixedly connected to the first mounting frame 3, the output end of the first cylinder 401 is fixedly connected to the mounting plate 402, and the first fixing plate 501 is fixedly connected to the front side of the mounting plate 402.

[0034] When installing the magnet in this way, the first cylinder 401 is started to drive the blanking assembly 5 and the loading piece 6 to move downward and contact the head-mounted shaft 2. At this time, the blanking hole 8 corresponds to the magnet installation position of the head-mounted shaft 2, so that the installation is better.

[0035] like Figure 1 and Figure 2 As shown: In this embodiment, the separation component 9 includes a second cylinder 901 fixedly connected to the left side of the unloading component 5, the telescopic end of the second cylinder 901 is fixedly connected to an L-shaped rod 902, one side of the L-shaped rod 902 is fixedly connected to a separation rod 903, and one end of the separation rod 903 is located inside the transverse groove 7.

[0036] In this way, the second cylinder 901 is extended to drive the L-shaped rod 902 and the separation rod 903 to move. During the movement, the separation rod 903 pushes the bottom magnet to the drop hole 8, and then the second cylinder 901 drives the separation rod 903 to contract. Due to the effect of gravity, the magnet at the bottom will fall into the horizontal groove 7 again.

[0037] like Figure 2 and Figure 4 As shown: In this embodiment, the pressing assembly 10 includes a third cylinder 1001 fixedly connected to the front side of the blanking assembly 5, the telescopic end of the third cylinder 1001 is fixedly connected to a movable block 1002, the movable block 1002 is fixedly connected to a pressing rod 1003, and the bottom end of the pressing rod 1003 corresponds to the position of the blanking hole 8.

[0038] In this way, the third cylinder 1001 is started to extend and drive the movable block 1002 and the lower pressure rod 1003 to move downward. During the movement, the lower pressure rod 1003 can load the magnet from the blanking hole 8 into the interior of the head-mounted rotating shaft 2.

[0039] like Figure 2 and Figure 6 As shown: in this embodiment, a second through slit 601 communicating with the blanking hole 8 is provided on the front side of the loading member 6 .

[0040] When the magnet in the blanking hole 8 is stuck in this way, the thin sheet can be inserted into the second through-slit 601 to move it downward, thereby avoiding the phenomenon of being stuck.

[0041] A re-pressing mechanism comprises the automatic magnetizing mechanism as described above.

[0042] like Figure 1 and Figure 5 As shown: In this embodiment, it also includes a second mounting frame 11, and the front top of the second mounting frame 11 is fixedly connected to a fourth cylinder 12, the telescopic end of the fourth cylinder 12 is fixedly connected to a pressure plate 13, the front side of the upper surface of the pressure plate 13 is fixedly connected to a fifth cylinder 14, the telescopic end of the fifth cylinder 14 is fixedly connected to a re-pressure rod 15, and the bottom end of the re-pressure rod 15 passes through the bottom end of the pressure plate 13.

[0043] The working turntable 1 is arranged in this way to rotate the head-mounted shaft 2 with the magnet installed to the re-pressing mechanism. At this time, the fourth cylinder 12 is started to extend and drive the pressure plate 13 to contact the head-mounted shaft 2, and then the fifth cylinder 14 is started to extend and drive the re-pressing rod 15 to move downward. During the movement, the re-pressing rod 15 can firmly install the magnet inside the head-mounted shaft 2.

[0045] Such arrangement of the roller 17 can support the working turntable 1 and reduce the friction between the roller 17 and the working turntable 1, thereby making the working turntable 1 rotate better.

[0046] Working principle: When in use, place the magnet to be assembled in the through hole 504 on the blanking rod 503. Since the size of the through hole 504 is fixed, larger magnets cannot be installed and will be separated. Qualified magnets will fall into the horizontal groove 7 due to gravity. When installing the magnet, start the first cylinder 401 to drive the blanking assembly 5 and the loading piece 6 to move downward and contact the head-mounted shaft 2. At this time, the blanking hole 8 corresponds to the magnet installation position of the head-mounted shaft 2. Then the second cylinder 901 extends to drive the L-shaped rod 902 and the separation rod 903 to move. During the movement, the separation rod 903 pushes the bottom magnet to the blanking hole 8, and then the second cylinder 901 drives the separation rod 9 03 contracts. Due to the effect of gravity, the magnet at the bottom will fall into the horizontal groove 7 again. Then the third cylinder 1001 is started to extend to drive the movable block 1002 and the lower pressure rod 1003 to move downward. During the movement, the lower pressure rod 1003 can load the magnet from the blanking hole 8 into the inside of the head-mounted shaft 2. Then the working turntable 1 rotates the head-mounted shaft 2 with the magnet loaded to the re-pressing mechanism. At this time, the fourth cylinder 12 is started to extend to drive the pressure plate 13 to contact the head-mounted shaft 2. Then the fifth cylinder 14 is started to extend to drive the re-pressing rod 15 to move downward. During the movement, the re-pressing rod 15 can firmly install the magnet inside the head-mounted shaft 2 to ensure the installation quality of the magnet.
