[0033] A controller 31 is disposed on the upper wall of the material receiving base 1 .

[0034] The controller 31 is electrically connected to the upper proximity switch 18 , the lower proximity switch 19 , the speed measuring electromagnet 21 and the deceleration electromagnet 24 , respectively.

[0035] When in use, in the initial state, the telescopic rod 27 is extended, the telescopic rod 27 drives the locking column 28 to be inserted into the locking port 30, the punching sheet type vertical guide column 11 is rotated, and the punching sheet type vertical guide column 11 is rotated along the limit column 29 to increase the distance the limit column 29 extends into the inside of the punching sheet type vertical guide column 11, the threaded sleeve 6 is screwed into the outside of the fixed column 3, and the punching sheet type sliding column 7 is installed on the upper wall of the receiving base 1;

[0036] Specifically, the punching sheet type vertical guide column 11 is rotated, and the punching sheet type vertical guide column 11 drives the vertical connecting column 12 to be screwed into the vertical threaded hole 10, and the distance that the limit column 29 extends into the punching sheet type vertical guide column 11 is shortened. The punching sheet type vertical guide column 11 and the punching sheet type sliding column 7 are coaxially vertically arranged, and the telescopic rod 27 is pulled. The telescopic rod 27 is shortened and drives the locking column 28 to extend out of the locking port 30. The telescopic rod 27 is changed to a shortened setting, and the processed magnetic pole punching is inserted into the outer side of the punching sheet type vertical guide column 11. The magnetic pole punching slides down along the receiving base 1 to the outer side of the punching sheet type sliding column 7. The magnetic pole punching continues to slide and fall to fit the upper wall of the carrying plate 8, and then the processed magnetic pole punching can be collected by the punching sheet type sliding column 7;

[0037] When the processed magnetic pole punching sheet is inserted into the outer side of the punching sheet type vertical guide column 11, the controller 31 controls the upper proximity switch 18 and the lower proximity switch 19 to start, the upper proximity switch 18 senses and records the magnetic pole punching sheet at the beginning of sliding down, and the lower proximity switch 19 senses and records the magnetic pole punching sheet when it slides out of the outer side of the punching sheet type vertical guide column 11. The controller 31 controls the speed measuring electromagnet 21 to start, and the speed measuring electromagnet 21 is energized to generate magnetism. Under the same magnetic field strength of the speed measuring electromagnet 21, the processed magnetic pole punching sheets slide one by one from the outer side of the punching sheet type vertical guide column 11 to the upper wall of the supporting plate 8 on the outer side of the punching sheet type sliding column 7 for storage. The magnetic pole punching sheets are affected by the speed measuring electromagnet in the process of falling along the punching sheet type vertical guide column 11. 21. The force of the magnetic field, the magnetic pole sheet with greater magnetism is subjected to greater descent resistance, and the time interval between the upper proximity switch 18 sensing and the lower proximity switch 19 sensing is longer. On the contrary, the magnetic pole sheet with smaller magnetism is subjected to less descent resistance, and the time interval between the upper proximity switch 18 sensing and the lower proximity switch 19 sensing is shorter. Thus, the magnetism of the magnetic pole sheet itself can be detected, and then the magnetic property test of the magnetic pole sheet is completed. According to the requirements of the operating personnel, the waste magnetic pole sheet that does not meet the descent time is removed from the upper wall of the carrying plate 8, and the waste magnetic pole sheet slides out along the sheet-type sliding column 7 and the sheet-type vertical guide column 11, completing the material collection operation of the magnetic pole sheet that meets the requirements.

[0038] When the magnetic pole punch slides from the outer side of the punch type vertical guide column 11 to the outer side of the punch type sliding column 7, the controller 31 controls the deceleration electromagnet 24 to start, and the deceleration electromagnet 24 is energized to generate magnetism. The deceleration electromagnet 24 absorbs the magnetic pole punch in the process of descent through magnetic force, slowing down the falling speed of the magnetic pole punch, and ensuring that the magnetic pole punch falls to the upper wall of the carrying plate 8 for storage without damage;

[0039] After the magnetic pole sheet is collected, the telescopic rod 27 is pulled, and the telescopic rod 27 is extended to drive the locking column 28 to be inserted into the locking port 30, and the punching sheet type vertical guide column 11 is rotated, and the punching sheet type vertical guide column 11 drives the vertical connecting column 12 to be screwed out from the vertical threaded hole 10 of the punching sheet type sliding column 7, and the distance that the limit column 29 extends into the inside of the punching sheet type vertical guide column 11 increases, and the punching sheet type sliding column 7 is rotated, and the punching sheet type sliding column 7 drives the threaded sleeve 6 to be screwed out from the outside of the fixed column 3, The punching sheet type sliding column 7 is taken out of the upper wall of the receiving base 1, thereby completing the receiving operation of the magnetic pole punching sheet. The new punching sheet type sliding column 7 is screwed into the outside of the fixed column 3 again through the threaded sleeve 6. The punching sheet type vertical guide column 11 rotates to drive the vertical connecting column 12 to be screwed into the vertical threaded hole 10, pushing the telescopic rod 27. The telescopic rod 27 is shortened to drive the locking column 28 to extend from the locking port 30 to receive the processed magnetic pole punching sheet. Repeat the above operation when using it next time.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
