[0034] Working principle:

[0035] The plurality of magnet bars are placed horizontally into the material box 61, each magnet bar will roll backward along the slope of the bottom surface of the material box 61, the retractable end of the double-rod pneumatic cylinder 62 is driven to retract inward to drive the pushing plate 63 to move downward until the first feeding slope 631 is lower than the last magnet bar, then the last magnet bar will continue to roll backward and be above the first feeding slope 631, then the retractable end of the double-rod pneumatic cylinder 62 is driven to extend outward to drive the pushing plate 63 to move upward, and then the last magnet bar is lifted by the first feeding slope 631, because the first feeding slope 631 is set high in front and low at the back, so the last magnet bar always has a tendency to roll backward and slide along the rear inner wall of the material box 61 during the rising process, until the rear edge of the first feeding slope 631 is higher than the rear edge of the top opening of the material box 61, then the last magnet bar will roll backward through the rear edge of the top opening of the material box 61 and fall onto the second feeding slope 641 on the two receiving plates 64, and then fall downward along the two second feeding slopes 641 to the upper side of the two supporting plates 51, until it rolls into the two V-shaped grooves 5101 at the front.

[0036] The retractable ends of the first single-rod pneumatic cylinder 58 and the second single-rod pneumatic cylinder 59 in the material moving assembly 5 are simultaneously driven to retract inward to drive the slide table pneumatic cylinder 511 to move downward, and then the carrier plate 56 and the plurality of traction blocks 55 drive the supporting strip 52 to move downward, thereby driving the four first pneumatic fingers 53 to move downward, during this process, the retractable end of the slide table pneumatic cylinder 511 is driven to retract inward to drive the four first pneumatic fingers 53 to move forward with the carrier plate 56, the plurality of traction blocks 55, and the supporting strip 52, until the first pneumatic finger 53 at the front moves below the above-mentioned magnet bar, then the retractable ends of the first single-rod pneumatic cylinder 58 and the second single-rod pneumatic cylinder 59 are simultaneously driven to extend outward to drive the four first pneumatic fingers 53 to move upward, and the two clamping jaws of each first pneumatic finger 53 are simultaneously driven to move away from each other, until the two first clamping blocks 54 on the first pneumatic finger 53 at the front are located at the front and rear sides of the above-mentioned magnet bar, respectively, then the two clamping jaws of each first pneumatic finger 53 are driven to move towards each other to clamp the above-mentioned magnet bar, then the retractable ends of the first single-rod pneumatic cylinder 58 and the second single-rod pneumatic cylinder 59 are continuously driven to extend outward to lift the above-mentioned magnet bar, and then the above-mentioned magnet bar is moved backward with the slide table pneumatic cylinder 511, until the above-mentioned magnet bar is above the second V-shaped groove 5101 from front to back, then the retractable ends of the first single-rod pneumatic cylinder 58 and the second single-rod pneumatic cylinder 59 are driven to retract inward to move the above-mentioned magnet bar downward, until the above-mentioned magnet bar falls into the second V-shaped groove 5101 from front to back, then the two clamping jaws of each first pneumatic finger 53 are driven to move away from each other to release the above-mentioned magnet bar, and finally the above-mentioned steps are repeated to transfer the next magnet bar that has completed feeding in the same way.

[0037] The telescopic end of the first pen rod cylinder 32 in the driving rotating assembly 3 is driven to extend outward to swing the end of the swing rod 34 downward, and then the driving wheel 35 is moved downward by the transmission shaft 36 until the driving wheel 35 is pressed on the magnet bar, and then the rotating shaft of the deceleration motor 38 is started to rotate, and then the transmission shaft 36 is rotated by the chain 39 and the two chain wheels 37 to rotate the driving wheel 35, and then the magnet bar is rotated by the friction between the driving wheel 35 and the magnet bar. Since the left end of the magnet bar is arranged between the two first pulley combinations and the two second pulley combinations in the left support assembly 8 and the right end of the magnet bar is arranged between the two first pulley combinations and the two second pulley combinations in the right support assembly 8 after the magnet bar falls into the second V-shaped groove 5101 from front to back, each first pulley 85 and each second pulley 9 can roll along the outer wall of the magnet bar, thereby effectively supporting the magnet bar.

[0038] Then, the telescopic ends of the second pen rod cylinders 46 in the two cutting assemblies 4 are simultaneously driven to extend outward to move the two lifting blocks 42 downward, and then the cutting motor 44 and the cutting blade 45 are moved downward by the knife holder 43, and at the same time, the rotating shaft of the cutting motor 44 in each cutting assembly 4 is started to rotate, and then the two cutting blades 45 are rotated, and when the edges of the two cutting blades 45 contact the magnet bar, the magnet bar is cut, and then two annular cutting grooves are processed on the magnet bar, but the magnet bar cannot be completely cut off, and only a residual section with an outer diameter of about 1 mm is left.

[0039] After cutting, the cutting motor 44 in each cutting assembly 4 is turned off, and the telescopic ends of the second pen rod cylinders 46 in the two cutting assemblies 4 are driven to retract inward to move the two cutting blades 45 upward to reset; then the deceleration motor 38 is turned off, and the telescopic end of the first pen rod cylinder 32 is driven to retract inward to move the driving wheel 35 upward to move away from the magnet bar; then the four first pneumatic fingers 53 in the material moving assembly 5 are driven to move downward first, and then move forward until the second first pneumatic finger 53 from front to back is located below the cut magnet bar, and then the four first pneumatic fingers 53 are driven to move upward first, and then the cut magnet bar is clamped by the second first pneumatic finger 53 from front to back, at this time, the first pneumatic finger 53 in front will also clamp the magnet bar that has just completed feeding, and then the four first pneumatic fingers 53 are driven to move upward first, and then move backward until the cut magnet bar is located above the third V-shaped groove 5101 from front to back, and then the four first pneumatic fingers 53 are driven to move downward first, and then the two clamping jaws are released, so that the cut magnet bar is moved backward by one position, and the magnet bar that has just completed feeding is also moved backward by one position and starts to be cut, and so on.

[0040] When the cut magnet rod material moves into the last two V-shaped grooves 5101, the extension end of the third pen barrel cylinder 72 in each distribution unit is driven to extend outward to drive the two swing plates 75 to move relative to each other by means of the two moving plates 73, and the two clamping jaws on each second pneumatic finger 76 are driven to move away from each other, until the two second clamping blocks 77 on each second pneumatic finger 76 are respectively located on the front and rear sides of the magnet rod material, then the two clamping jaws on each second pneumatic finger 76 are driven to move close to each other to clamp the two ends of the cut magnet rod material, and the extension end of the third single-head cylinder 711 in the pressing unit is driven to extend outward to drive the positioning head 712 to move downward to press the magnet rod material; finally, the extension end of the two fourth pen barrel cylinders 74 is driven to extend outward to drive the two knocking heads 78 to move downward, and then press the two swing plates 75 downward to make the end portions of the swing plates 75 swing downward, so that the brittleness of the magnet rod material is used to quickly and easily break the two residual sections, and the two ends of the broken magnet rod material are held by the second pneumatic finger 76 and will not fall; after breaking, the extension end of the two fourth pen barrel cylinders 74 is driven to retract inward to drive the two knocking heads 78 to move upward away from the swing plates 75, and the end portions of the swing plates 75 swing upward to reset by means of the gravity of the second pneumatic finger 76 and the magnet rod material, until the threaded end of the limiting bolt 79 is engaged with the threaded hole in the end portion of the swing plate 75.

[0041] Finally, the extension end of the third pen barrel cylinder 72 in each distribution unit is driven to retract inward to drive the two ends of the broken magnet rod material to move outward by means of the two second pneumatic fingers 76, until the two ends of the broken magnet rod material move above the two first receiving boxes 10, and after the two clamping jaws of each second pneumatic finger 76 are released, the two ends of the broken magnet rod material will fall into the two first receiving boxes 10 respectively to complete automatic collection, and the magnet rod material remaining on the two supporting plates 51 moves above the two discharge slopes 5102 under the drive of the last first pneumatic finger 53 in the material moving assembly 5, and after the two clamping jaws of the last first pneumatic finger 53 are released, the residual magnet rod material will fall into the second receiving box 11 to complete automatic collection, thereby forming a cycle.

[0042] The present application first processes two annular cutting grooves on the rod material, and then breaks the rod material at the two annular cutting grooves by utilizing the brittleness of the neodymium iron boron magnet, and since the outer diameter of the residual section is small, the main structure is not damaged, so that three columnar neodymium iron boron magnets are obtained at one time, thereby greatly improving the processing efficiency; moreover, the automatic feeding, automatic moving and automatic discharging of the rod material are realized by means of the feeding assembly 6, the material moving assembly 5 and the material distribution assembly 7, thereby making the whole process without manual operation, so that the operation steps are simplified and the labor cost is reduced; in addition, the operator is completely avoided from close contact with the cutting blade to eliminate the safety hazard.

[0043] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some of the technical features can be replaced by equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
