[0040] Specifically, the blanking box 111 is used to store the neodymium iron boron pipe to be processed, its internal space is adapted to the stacking requirements of the pipe, an outlet is arranged at the front end for the release of the pipe, and the two clamping plates 103 are clamped and fixed on the second conveying platform 9; the sixth electric push rod 112 is installed at the front end of the blanking box 111, and is driven by the output shaft to drive the baffle 113 to open and close, which is an execution component for controlling the release of the pipe; the baffle 113 is fixed with the output shaft of the sixth electric push rod 112, tightly fits the inner wall of the outlet of the blanking box 111 when closed, blocks the rolling of the pipe, and allows the release of a single pipe when opened, realizes the precise blanking of "single pipe at a time", and avoids the chaos caused by the synchronous rolling of multiple pipes in the pretreatment.

[0041] The working principle is that, in use, first, the blanking preparation before starting the equipment is performed: the neodymium iron boron pipes are placed one by one in the blanking box 111, it is ensured that the pipes in each group of blanking boxes 111 are stacked neatly, the subsequent release is prevented from being stuck due to the stacking of the pipes being inclined, after the filling operation of the multiple groups of blanking boxes 111 is completed, the cabinet door of the laser cutting machine box 1 is closed to ensure the safety of the equipment operation, then the relative positions of the clamping assembly 10 and the blanking assembly 11 are adjusted: the first slide rail 101 is fixed along the length direction of the second conveying platform 9, the distance between the two second slide rails 102 is adjusted by sliding along the first slide rail 101, the second slide rail 102 slides transversely along the first slide rail 101, and then the clamping plate 103 moves up and down along the sliding groove of the second slide rail 102, and the clamping plate 103 is adjusted to the clamping position adapted to the outer wall of the blanking box 111, so that the blanking box 111 is stably clamped between the two clamping plates 103; then the second slide rail 102 drives the blanking assembly 11 to move close to the feeding mechanism 5, the second electric track 8 is started to drive the second conveying platform 9 to move transversely along the upper end of the laser cutting machine box 1, so that the outlet of one group of blanking boxes 111 is axially aligned with the cutting axis of the laser cutting machine body 7, laying a foundation for the subsequent precise conveying of the pipe; The blanking assembly 11 is started to release a single pipe: the sixth electric push rod 112 is started, the output shaft of the sixth electric push rod 112 drives the baffle 113 to move upward, so that the pipe in the blanking box 111 moves to the outlet direction under the action of gravity; when the first pipe completely rolls out of the outlet of the blanking box 111, the sixth electric push rod 112 immediately reverses the action to drive the baffle 113 to close downward, the baffle 113 tightly fits the inner wall of the outlet of the blanking box 111 when closed, avoids the pipe being stuck in the gap of the outlet, and ensures that only one pipe is released at a time, preventing the subsequent pretreatment from being chaotic due to the synchronous rolling of multiple pipes. The released pipe slides down along the inclined support 511 by utilizing the cylindrical structure and the action of gravity, the surface of the inclined support 511 is smoothly treated to reduce the rolling resistance, and enters the pretreatment link; The trimming assembly 51 is triggered to work during the sliding process of the round pipe: the infrared probe 513 outside the slope support 511 monitors the rolling position of the round pipe in real time, and when the round pipe rolls to the middle of the slope support 511 at a preset detection point, the infrared probe 513 immediately sends a signal to drive the output shaft of the two symmetrical first electric push rods 514 to extend transversely to clamp the round pipe from both sides, thereby achieving preliminary positioning; the flexible rubber coating outside the output shaft of the first electric push rod 514 is in flexible contact with the outer wall of the round pipe to avoid damage to the surface of the round pipe caused by rigid collision. Then the second electric push rod 517 is started, and the output shaft thereof extends axially outward along the first sleeve 515 to drive the flexible polishing cylinder 518 to be sleeved into and clamped on the round pipe from both ends; the pressure sensor 519 outside the flexible polishing cylinder 518 feeds back clamping force data in real time, and when the clamping force reaches a preset threshold, the second electric push rod 517 stops working; then the first motor 5110 is started, and the output shaft thereof drives the worm 5111 to rotate, the worm 5111 meshes with the round tooth ring 516 outside the first sleeve 515 to drive the first sleeve 515 to rotate around its axis, thereby synchronously rotating the flexible polishing cylinder 518 to polish the burrs and notches at both ends of the round pipe; during the polishing process, the output shaft of the first electric push rod 514 is synchronously retracted to provide a smooth flow path for the subsequent continuous sliding of the round pipe; At the same time when the trimming assembly 51 works, the cleaning assembly 52 is started synchronously: first, the output shaft of the four third electric push rods 521 is synchronously retracted to drive the mounting box 522 to be smoothly lifted upward along the through hole of the slope support 511, thereby ensuring that the mounting box 522 is height-adapted to the round pipe and enabling the open clamp plate 524 to be accurately wrapped around the round pipe clamped by the flexible polishing cylinder 518; the third motor 528 is started, and the output shaft thereof drives the driving gear 529 to rotate inside the open clamp plate 524, the driving gear 529 meshes with the teeth outside the C-shaped clamping ring 525, and meanwhile, the plurality of limiting gears 527 inside the open clamp plate 524 meshes with the C-shaped clamping ring 525 to limit the C-shaped clamping ring 525 to only make circular motion along the outer periphery of the round pipe, thereby preventing tooth disengagement or deviation; the cleaning brush 526 on the inner wall of the C-shaped clamping ring 525 rotates with the ring body to clean the oil stains and dust on the outer wall of the round pipe in a circular manner; then the second motor 5210 is started, and the output shaft thereof drives the threaded rod 523 to rotate inside the mounting box 522, the threaded rod 523 is screwed with the open clamp plate 524, and the roller at the lower end of the open clamp plate 524 rolls along the inner wall of the mounting box 522 to drive the open clamp plate 524 to translate axially along the round pipe, so that the cleaning brush 526 covers the entire outer wall length of the round pipe to completely remove residual oil stains and avoid affecting the subsequent spraying effect; After the edge trimming and cleaning process is completed, the round tube continues to slide down the inclined support 511 and finally rolls onto the adsorption pad 512 range at the lower part of the inclined support 511, triggering the work of the spraying assembly 53: starting two fourth motors 531, the output shafts of which drive the fixed rotating shaft 532 to rotate, and the fixed rotating shaft 532 drives the eccentric plate 533 to make eccentric circular motion; the push ring 534 on the outer side of the eccentric plate 533 pushes the sliding rod 535 transversely with eccentric motion, and the sliding rod 535 makes reciprocating linear motion along the axis of the round tube under the limiting of the clamping blocks on both sides of the inclined support 511, thereby driving the atomizing spray head 536 at the end of the sliding rod 535 to move synchronously and reciprocally; the atomizing spray head 536 draws the suspension from the titanium dioxide suspension tank 537 through the pipeline to uniformly spray on the outer wall of the round tube in the form of atomization; the adsorption pad 512 is made of high water-absorbing flexible material, which on the one hand adsorbs the excess suspension dripping during the spraying process, and on the other hand forms a flexible support for the round tube to prevent displacement of the round tube during the spraying process, while accelerating the adhesion and preliminary solidification of the suspension on the outer wall of the round tube, enhancing the laser absorption rate and reducing reflection, and preventing molten material from splashing and adhering; After the spraying is completed, the round tube slides out of the adsorption pad 512 under the action of gravity and smoothly enters the inner side of the fixed frame 61 of the polishing mechanism 6: at this time, the electromagnetic clamping plate 65 is in a de-energized state to avoid position deviation of the round tube caused by early adsorption; after the round tube completely enters between the electromagnetic clamping plates 65, the electromagnetic clamping plates 65 are energized to generate a uniform magnetic field, which axially adsorbs the round tube from both ends of the round tube, so that the axis of the round tube is accurately aligned with the cutting axis of the laser cutting machine body 7, and the non-mechanical contact characteristic of magnetic positioning is used to avoid indentation or deformation at both ends of the round tube. Then the first electric track 3 is started, which drives the first conveying platform 4 to move backward along the length direction of the marble base 2, and sends the round tube positioned on the fixed frame 61 into the working range of the laser cutting machine body 7; the laser cutting machine body 7 is started, and the round tube is cut into multiple round sheet magnets of a predetermined specification according to a preset cutting program; during the cutting process, the soft connection structure adopted by the marble base 2 and the laser cutting machine box 1 can effectively filter low-frequency vibration of the ground, prevent vibration from affecting the stability of the laser light path, and ensure the cutting tolerance accuracy; After laser cutting is completed, burrs at the inner wall cut of the disc magnet are polished by starting the polishing mechanism 6: first, start the two fifth electric push rods 67 on the inner side of the mounting block 66, the output shaft of which extends radially outward along the mounting block 66, driving the polishing strip 68 to approach the inner wall of the disc magnet, and adjusting the length of the polishing strip 68 to make the polishing strip 68 maintain uniform contact pressure with the inner wall of the disc; simultaneously start the fifth motor 64 and the fourth electric push rod 63: the output shaft of the fifth motor 64 drives the fourth electric push rod 63 to rotate in the second sleeve 62 through the coupling, the second sleeve 62 is rotationally connected with the fixed frame 61, and the axis is coincident with the axis of the circular tube, ensuring coaxial rotation of the fourth electric push rod 63, the output shaft of the fourth electric push rod 63 drives the mounting block 66 and the polishing strip 68 to extend axially to the inner wall of the disc magnet, and the polishing strip 68 rotates with the fourth electric push rod 63 to polish the burrs at the inner wall of the disc magnet, completely removing the burrs; After polishing is completed, the processed disc magnet is taken out; when all the circular tubes in the current group of discharge boxes 111 are processed, the second electric track 8 is started to drive the second conveying platform 9 to move the next group of discharge boxes 111 full of circular tubes to the working position opposite the inclined support 511, and at the same time, the staff can replenish the empty discharge boxes 111, realizing three-material groove circulation feeding and continuous production without stopping, and so on to complete batch processing.
