[0085] Step 8: The material return mechanism 15 is started to push the finished product out from the placement device 1 to complete the operation.

[0086] In the fifth step, the magnetic pole 52 is required to be inserted at two opposite magnetic pole 52 installation positions of the housing 51. It is better to insert the magnetic pole 52 at two opposite positions at the same time. That is, in actual operation, the magnetic pole 52 is required to be inserted diagonally inside the housing 51. That is, in actual assembly, the magnetic pole 52 is required to be inserted symmetrically. Such a setting can reduce the difficulty of assembling the magnetic pole 52, and can well avoid the magnetic pole retaining spring 53 from being squeezed and misplaced when the magnetic pole 52 is installed later. At the same time Symmetrical insertion of the magnetic poles 52 can ensure that the force on the housing 51 is more uniform; it can avoid the housing 51 from shifting when the magnetic poles 52 are inserted on one side; in addition, the magnetic poles 52 of the present invention are required to be inserted into the housing 51 in pairs to avoid the housing 51 from shifting when the magnetic poles 52 are inserted alone; and it should be noted that the magnetic poles 52 are first inserted into the housing 51, and then the magnetic poles 52 are pressed into place at one time by a pressing mechanism. This arrangement avoids repeated pressing of the magnetic poles 52, thereby greatly improving the assembly efficiency.

[0087] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
