[0038] Specifically, the drum 31 is a polygonal column.

[0039] The operation process of the magnetic block automatic feeding device provided by the embodiment of the present invention is:

[0040] Step S1, first, in the receiving grooves 324 on both sides of the bottom plate 322, a plurality of magnetic blocks are arranged in sequence into magnetic strips in a manner of attracting opposite poles. According to the process requirements, the N pole or S pole of the magnetic strips can be facing downwards; then, the card strips 323 of the cover plate 321 are plugged into the card slots 325 of the bottom plate 322, thereby completing the assembly of the magazine 32; then, the limiting block 36 is pushed upward by hand, and the magazine 32 with the magnetic strips is installed to the side wall of the drum 31 through the slide slot 35. When the magazine 32 is completely placed in the slide slot 35, the limiting block 36 returns to its original position by the elastic force of the spring, so that when the top of the magazine 32 abuts against the limiting block 36, the installation of the magazine 32 is completed, and other magazines 32 are also installed in this way;

[0041] Step S2, the controller starts the Hall sensor 410, and the Hall sensor 410 detects whether the direction of the N pole or S pole of the magnetic strip in the magazine 32 is placed correctly; if the direction of the N pole or S pole of the magnetic strip is placed correctly, the Hall sensor 410 lights up and sends a signal of correct polarity to the controller, and the controller enters the next step after receiving the signal of correct polarity; if the direction of the N pole or S pole of the magnetic strip is placed incorrectly, the Hall sensor 410 does not light up, and sends a signal of incorrect polarity to the controller, and the controller issues an alarm prompt; at this time, it is necessary to manually take the magazine 32 out of the slide slot 35 on the side wall of the drum 31; then, push the cover plate 321 upward to separate the card strip 323 from the card slot 325, so as to separate the cover plate 321 from the bottom plate 322; then, repeat step S1;

[0042] Step S3, the controller starts the motor 21, and the motor 21 drives the roller 31 to rotate through the reducer 22, so that the two receiving grooves 324 in the magazine 32 are opposite to the two stepped grooves 49, that is, the magnetic strips in the two receiving grooves 324 are opposite to the two stepped grooves 49;

[0043] Step S4, the controller starts the vertical cylinder 43, and the cylinder rod of the vertical cylinder 43 drives the lifting platform 46 and the two iron sheets 47 to rise. After the two iron sheets 47 penetrate the two step grooves 49, they are respectively adsorbed together with the first magnetic blocks at the bottom of the two magnetic strips; then, the controller controls the cylinder rod of the vertical cylinder 43 to descend, and the cylinder rod of the vertical cylinder 43 drives the lifting platform 46 and the two iron sheets 47 to descend, so that the magnetic strips in the two accommodating grooves 324 move downward with the iron sheets 47. Since the size of the opening at the upper end of the step groove 324 is larger than the size of the magnetic block, and the size of the opening at the lower end of the step groove 324 is smaller than the size of the magnetic block, the depth of the opening at the upper end of the step groove 324 is equal to the vertical length of the magnetic block, so that the first magnetic blocks at the bottom of the two magnetic strips are both stuck at the upper end of the step groove 324, and the two iron sheets 47 continue to return to their original positions together with the descent of the cylinder rod of the vertical cylinder 43 and the lifting platform 46, so that the first magnetic block at the bottom of the two magnetic strips is separated from the two iron sheets 47;

[0044] Step S5, the controller starts the optical fiber sensor 411, and the optical fiber sensor 411 detects that there is a magnetic block in the step groove 324 through the detection hole 481. At this time, the controller starts the horizontal cylinder 44, and the cylinder rod of the horizontal cylinder 44 drives the mounting plate 45 and the vertical cylinder 43 to move forward, and the mounting plate 45 drives the loading platform 48 to move forward in the gap 421, and the loading platform 48 drives the magnetic blocks in the two step grooves 324 to enter the next process; after the magnetic blocks in the two step grooves 324 are removed in the next process, the controller controls the horizontal cylinder 44 to move backward, and the cylinder rod of the horizontal cylinder 44 drives the mounting plate 45 and the vertical cylinder 43 to move backward, and the mounting plate 45 drives the loading platform 48 back to the gap 421;

[0045] Step S6, repeat steps S4 and S5 until the optical fiber sensor 411 detects that there is no magnetic block in the stepped groove 324, and repeat steps S3, S4 and S5 until there is no magnetic block in the receiving grooves 324 of all the magazines 32, thereby completing the assembly of all the magnetic blocks in the magazine 32.

[0046] The technical effect of the automatic feeding device for magnetic blocks provided by the embodiment of the present invention is as follows: compared with the prior art, the present invention brings a large number of magnetic blocks together through the roller 31 and the magazine 32 of the feeding device 3; detects whether the N pole or S pole of the magnetic strip in the magazine 32 is placed correctly through the Hall sensor 410; separates the magnetic blocks from the magnetic strip in the magazine 32 one by one through the vertical cylinder 43, lifting platform 46, iron sheet 47 and stepped groove 49 of the separation device 4; detects whether there are magnetic blocks in the stepped groove 324 through the optical fiber sensor 411; supplies the magnetic blocks in the two stepped grooves 324 to the next process through the horizontal cylinder 44, mounting plate 45 and loading platform 48 of the separation device 4; realizes automated operation throughout the process, with high feeding efficiency, meets the requirements of mass assembly of magnetic blocks, reduces labor costs, and improves production efficiency.
