[0057] See also Figure 7 and Fig. 27 A connecting plate 629 is welded and fixed on the second reinforcing plate 628, and a second gear shaft 630 is rotatably connected to the connecting plate 629. A second circular gear 631 is welded and fixed to the bottom end of the second gear shaft 630, and a second rack 632 is meshed and connected to the second circular gear 631.

The length of a rack 623 is equal, the cross-section of the flexible grinding block 634 is circular, and the second gear shaft 630 is connected to the center of the flexible grinding block 634. Similarly, under the meshing action of the second circular gear 631 and the second rack 632, the flexible grinding block 634 can reciprocate while reciprocating, and can automatically and stably remove the oxide layer at the laser marking of the stainless steel thin round tube in the process of separating and cutting, which can ensure the clarity and durability of the mark, and at the same time ensure the adhesion and contrast of the laser mark.

[0058] The specific implementation process of the present invention is as follows: first, the staff can rotate the first one-way threaded rod 512 on both sides of the rotating drum 508. Under the simultaneous rotation of the first one-way threaded rod 512 on both sides, the threaded connecting plate 513 can be driven to move in the direction close to the rotating drum 508 or away from the rotating drum 508. Under the movement of the connecting plate 513, the hinged connecting rod 514 can push the support plate 516 on the top rod 515 to move outward or inward in the positioning groove 510. By adjusting the position of the support plate 516, the internal placement space of the positioning groove 510 can only accommodate one stainless steel thin round tube, so as to avoid the problem that the internal placement space of the positioning groove 510 is large during the subsequent unloading process of the stainless steel thin round tube, which affects the subsequent stable unloading work of the stainless steel thin round tube. The staff can place a stainless steel thin round tube in the topmost positioning groove 510. The round tube helps the adjustment work. Similarly, through the same operation, each support plate 516 in another rotating drum 508 can be adjusted, and the staff can rotate the two-way threaded rod 502 on the fixed plate 501. The rotation of the two-way threaded rod 502 can drive the limit frames 504 on the two side support plates 503 to move to the middle or both sides at the same time, and then drive the corresponding rotating drum 508 and the limit plates 506 to move synchronously. At this time, the limit plates 506 on both sides can move stably inside the feeding frame 4, so that the distance between the limit plates 506 on the limit frames 504 on both sides is equal to the length of the stainless steel thin round tube. It is only necessary to ensure that the limit plates 506 on the limit frames 504 on both sides are in contact with the two ends of the stainless steel thin round tube, and there is no need to squeeze and clamp the stainless steel thin round tube, so that the laser marking device can be applied to stainless steel thin round tubes of different diameters and lengths.

[0059] Then the staff can place the stainless steel thin round tube that needs laser marking in the feed frame 4. At this time, under the action of the stainless steel thin round tube's own gravity, the two ends of the stainless steel thin round tube at the bottom can pass through the feed slots 505 on the limit frames 504 on both sides and enter the positioning slots 510 at the top of the rotating cylinders 508 on both sides. Then, under the driving action of the first servo motor 532 on one side of the limit frame 504, the first turntable 533 and the rotating rod 534 can be driven to rotate synchronously through the output shaft. When the groove on the first turntable 533 rotates to align with the second turntable 537, the rotating rod 534 can drive the first lever 535 to move the second lever 538. At this time, under the driving action of the first lever 535, the second The lever 538 can drive the second rotating disk 537 and the rotating drum 508 to move synchronously through the transmission shaft 536. Since the groove on the first rotating disk 533 rotates to align with the second rotating disk 537, the second rotating disk 537 can rotate stably, and the first rotating disk 533 will not limit the rotation of the second rotating disk 537. When the first lever 535 moves away from the second lever 538, the second rotating disk 537 on the transmission shaft 536 and the rotating drum 508 stop rotating. At this time, the first rotating disk 533 fits with the second rotating disk 537 again and limits the second rotating disk 537 to prevent the rotating drum 508 from shaking when it stops rotating. This reciprocating process can drive the rotating drum 508 to rotate intermittently in an automatic and stable manner.

[0060] While the rotating drum 508 on one side rotates intermittently, the telescopic sleeve rod 509 on the transmission shaft 536 can drive the rotating drum 508 on the other side to rotate synchronously. Under the synchronous intermittent rotation of the rotating drums 508 on both sides, the stainless steel thin round tube inside the topmost positioning groove 510 rotates counterclockwise to the sponge block 627. At the same time, the other positioning groove 510 moves counterclockwise to the top. At this time, the next stainless steel thin round tube automatically falls into the next positioning groove 510. By analogy, the separation and loading of the stainless steel thin round tubes can be automatically completed. After the stainless steel thin round tubes are loaded, when the positioning groove 510 moves counterclockwise, The guide blocks 525 on both sides can move away from the guide grooves 530 on the guide ring 529. When the guide blocks 525 move away from the guide grooves 530 on the guide ring 529, the guide blocks 525 can automatically move toward the inside of the rotating drum 508 under the guidance of the inclined surface of the guide blocks 525. At this time, the traction rope 524 on the coil 523 can be automatically pulled under the movement of the guide blocks 525. At this time, the clamping plate 519 on the driven shaft 518 can be driven to automatically rotate toward the inside of the positioning groove 510 through the coil 523 on the traction rope 524 under the pulling action of the movement of the guide blocks 525. Under the joint rotation of the clamping plate 519, the rubber plate 520 can automatically clamp and fix the stainless steel thin round tube in the positioning groove 510; and the staff can rotate the second one-way threaded rod 528 on both sides of the limit frame 504 according to the diameter of the stainless steel thin round tube. Under the threaded rotation of the second one-way threaded rod 528, the guide ring 529 can be pushed to move inward or outward in the ring groove 527. Under the movement of the guide ring 529, the position of the guide groove 530 can be adjusted. By adjusting the position of the guide groove 530, the guide block 525 needs to move when it moves out of the guide groove 530. If the length of the traction rope 524 is longer or only a shorter distance is needed, the moving distance of the guide block 525 can be adjusted to adjust the pulling length of the traction rope 524, and then the rotation angle of the clamping plate 519 can be adjusted, so that stainless steel thin round tubes of different diameters can be automatically clamped, which can be applicable to different batches of stainless steel thin round tubes. The length and diameter of the stainless steel thin round tubes of the same batch are the same, so the above adjustment operation only needs to be adjusted once. When another batch of stainless steel thin round tubes needs to be laser marked, it is only necessary to adjust according to the length and diameter of the stainless steel thin round tubes through the same operation;

[0061] And during the intermittent rotation of the rotating drum 508, when the stainless steel thin round tubes are automatically separated and unloaded, the second servo motor 601 and the third servo motor 605 are in a driving state. Under the driving action of the second servo motor 601, the reciprocating screw 602 can be driven to rotate. During the rotation of the reciprocating screw 602, the mounting frame 603 connected by a thread can drive the ventilation tube 604 to reciprocate left and right. Under the movement of the ventilation tube 604, the ventilation pipe 616 on the upper side can drive the first reinforcing plate 617 to move synchronously, and then the liquid storage tank 618, the transfer frame 625 and the sponge block 627 can be driven to reciprocate synchronously through the first reinforcing plate 617. During the reciprocating motion of the liquid storage tank 618, the third servo motor 605 can be driven to reciprocate left and right. The first circular gear 622 on the gear shaft 621 performs left-right reciprocating motion on the first rack 623 on the first mounting plate 624. The meshing between the first rack 623 and the first circular gear 622 can drive the transfer frame 625 and the sponge block 627 to automatically and stably reciprocate during the left-right reciprocating motion through the first gear shaft 621. During the reciprocating rotation of the transfer frame 625, the through hole 626 on the transfer frame 625 is intermittently aligned with the through hole 626 on the liquid storage tank 618. The cleaning liquid in the liquid storage tank 618 can be intermittently transported to the sponge block 627. With the left-right reciprocating motion and reciprocating rotation of the sponge block 627, the middle laser marking position of the stainless steel thin round tube that intermittently moves counterclockwise to this place can be automatically cleaned.

[0062] Then, the stainless steel thin round tube continues to intermittently move counterclockwise. At this time, the stainless steel thin round tube moves to the ventilation tube 604. During the reciprocating motion of the ventilation tube 604, the third servo motor 605 can drive the exhaust fan 606 to rotate stably through the output shaft. During the continuous rotation of the exhaust fan 606, the air at the sponge block 627 can be sucked through the ventilation pipe 616 on the upper side, and the air at the flexible grinding block 634 and the laser marking machine 7 can be sucked through the ventilation pipe 616 on the lower side. Then, after the air is heated by the electric heating tube 608, filtered by the filter plate 609, dehumidified by the dehumidification screen plate 610, and adsorbed and purified by the activated carbon screen plate 611, the laser marking part of the cleaned stainless steel thin round tube can be dried.

[0063] Then the stainless steel thin round tube continues to intermittently move counterclockwise and moves to the flexible grinding block 634. Similarly, under the movement of the ventilator 604, the second reinforcing plate 628 can be driven to move synchronously through the ventilation tube 616 on the lower side, and then the connecting plate 629 and the flexible grinding block 634 can be driven to reciprocate synchronously through the second reinforcing plate 628. During the reciprocating movement of the connecting plate 629, the second circular gear 631 on the second gear shaft 630 can be driven to reciprocate left and right on the second rack 632 on the second mounting plate 633. By utilizing the meshing between the second rack 632 and the second circular gear 631, the flexible grinding block 634 can be driven to automatically and stably reciprocate during the reciprocating movement through the second gear shaft 630. The flexible grinding block 634 can be used to grind the laser marking position in the middle of the stainless steel thin round tube and remove the oxide layer.

[0064] Then the stainless steel thin round tube continues to intermittently move counterclockwise and moves to the laser marking machine 7. At this time, the laser marking machine 7 can perform laser marking on the middle part of the stainless steel thin round tube that has been cleaned, dried and polished. Then the stainless steel thin round tube continues to intermittently move counterclockwise and moves to the feed trough 531 and the guide frame 8. At the same time, the guide blocks 525 on both sides of the positioning groove 510 move again into the guide groove 530 on the guide ring 529. At this time, under the elastic action of the reset spring 526, the guide block 525 can be driven to automatically move into the guide groove 530 to complete the reset. At the same time, under the elastic action of the spiral spring 522 inside the connecting frame 521, the driven shaft 51 can be driven 8 is rotated and reset, and by driving the coil 523 to rotate automatically, the traction rope 524 can be reeled up to ensure the stability of the subsequent repeated use of the traction rope 524, and the rotation and reset of the driven shaft 518 can drive the clamping plate 519 to rotate to the storage groove 517 to complete the automatic reset. At this time, the stainless steel thin round tube in the positioning groove 510 can automatically roll to the guide frame 8 through the unloading groove 531 on the limit frame 504, and the stainless steel thin round tube can be automatically guided and unloaded by the guidance of the guide frame 8; in summary, by analogy, the integrated processing of separation, loading, cleaning, drying, grinding, laser marking and unloading of stainless steel thin round tubes can be automatically completed;

[0065] And during the operation of the ventilation tube 604, the exhaust fan 606 continuously rotates, so that the air at the sponge block 627 can be sucked through the ventilation pipe 616 on the upper side, and the air at the flexible grinding block 634 and the laser marking machine 7 can be sucked through the ventilation pipe 616 on the lower side. At this time, the dust and impurities generated by cleaning and grinding, as well as the toxic air at the laser marking site are sucked into the ventilation tube 604, and the dust and impurities in the air can be filtered under the action of the filter plate 609, and the air can be adsorbed and purified by the activated carbon mesh plate 611; and during the operation of the third servo motor 605, the rubber scraper 607 can be driven to move on the filter plate 609, The dust and impurities filtered by the filter plate 609 can then be hung on the through groove 613 at the bottom, and the dust and impurities can be automatically transported to the collection box 615 through the through groove 613 for automatic collection. The magnetism of the magnetic frame 614 can conveniently complete the magnetic suction installation and disassembly and separation of the collection box 615, and thus the collected dust and impurities can be conveniently transported and processed. Similarly, the magnetism of the magnetic plate 612 can conveniently complete the magnetic suction installation and disassembly and separation of the dehumidification mesh plate 610 and the activated carbon mesh plate 611, and thus ensure the convenience of subsequent replacement and cleaning of the dehumidification mesh plate 610 and the activated carbon mesh plate 611, and ensure the stability of the laser marking device in a long-term working state.
