Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting equipment, and in particular to a laser positioning and cutting device for metal processing. Background Art

[0002] Laser cutting equipment is a precision processing equipment that uses the high energy of laser beams to achieve material cutting. With its advantages of high precision and high efficiency, it occupies an important position in the fields of industrial manufacturing and precision processing. Laser cutting equipment is based on the thermal effect of lasers and achieves cutting through the following steps: the laser converts electrical energy into a high-energy laser beam (such as fiber lasers, CO2 lasers, etc.). The optical system (lenses, reflectors) focuses the laser beam into an extremely small spot with an energy density of 10 6 -10¹²W / cm², instantly heating the material to its melting or boiling point. The material is removed along a pre-set path through melting, vaporization, or plasma ablation.

[0003] Chinese patent CN118417720A discloses a sheet metal laser cutting device, including a laser emitting body for cutting sheet metal parts, a loading device for loading sheet metal parts, and a pressure separation device for preliminarily separating the sheet metal waste after cutting. The laser emitting body is arranged on the outside of the right end of the loading device, and the pressure separation device is installed on the lower side of the right end of the laser emitting body. In the present invention, through the arrangement of the conveying chain, the first U-shaped shell, the first mounting plate, the first supporting tooth, the first slot, the first plug-in plate, the positioning plate, the rubber square, the arc plate, the limit block, the deformation groove, the second U-shaped shell, the second mounting plate, the second supporting tooth, the second slot, and the second plug-in plate, the first mounting plate and the second mounting plate can be directly installed above the first U-shaped shell and the second U-shaped shell respectively, which is convenient for replacement when a large amount of metal waste is adhered to the surface of the first supporting tooth and the second supporting tooth.

[0004] During the production process of the above-mentioned device, the loading device can drive the sheet metal to the laser cutting position through the cooperation of structures such as the conveyor chain, the first U-shaped shell, the first mounting plate, the first supporting teeth and the second supporting teeth. However, during long-term continuous operation, a large amount of metal slag will remain on the surface of the first supporting teeth and the second supporting teeth. The currently commonly used solution is to directly replace the first supporting teeth and the second supporting teeth to remove the residual metal slag. This method not only increases the maintenance cost of frequent replacement of parts, but also when manually disassembling and replacing the supporting teeth, since both the disassembly and installation steps are manually operated, a great waste of manpower is wasted, resulting in the equipment needing to be shut down for a long time for processing, which greatly reduces the efficiency of the cutting work.

[0013] Preferably, the linkage unlocking mechanism includes a guide limiter installed on the second docking frame, a longitudinal channel and two transverse channels are provided inside the guide limiter, a stripping push block is installed inside each transverse channel, a third spring is installed between the stripping push block and the transverse channel, a multi-section plug plate is slidably installed inside the longitudinal channel, the bottom of the multi-section plug plate is fixedly connected to the guide rail, the top of the multi-section plug plate is provided with an unlocking angle, and both sides of the multi-section plug plate are provided with a stripping angle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves work efficiency and reduces equipment downtime: after the support rack has been used for a long time, if too much metal slag accumulates on the surface and it cannot be used any more, it needs to be replaced. The traditional manual disassembly and replacement method is not only cumbersome, but also wastes a lot of manpower, causing the equipment to be shut down for a long time for processing, which greatly reduces the efficiency of cutting work. In the rack maintenance device of this device, the movable adjustment device can switch the positions of the disassembly device and the rack cleaning device, and drive the disassembly device to move toward the support rack position. The disassembly device can perform an unlocking operation on the rack mounting seat. After unlocking, the support rack cooperates with the disassembly device to fall, and the disassembly device guides the falling support rack to the area to be processed, thereby realizing the automatic disassembly of the support rack. This method effectively reduces the replacement steps, avoids the tedious and time-consuming manual operation, significantly improves work efficiency, reduces the downtime of the equipment caused by replacing the support rack, ensures the continuous and stable operation of the device, and thus improves the overall production efficiency.

[0017] 2. The present invention reduces maintenance costs and extends the service life of components: the rack cleaning device in the rack maintenance device can effectively clean the metal slag on the support rack. During the laser cutting operation of sheet metal parts, metal slag will adhere to the surface of the support rack. In the past, the metal slag was usually removed by directly replacing the support rack, which increased the replacement frequency and maintenance costs of parts. However, the present invention uses the rack cleaning device to clean the surface of the support rack in time when it moves to the position of the rack maintenance device, reducing the amount of metal slag attached, thereby extending the service life of the support rack, reducing the cost of using the support rack, avoiding the high cost expenditure caused by frequent replacement of parts, and improving the economy of the device.

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] See also Figures 1 to 12As shown, a laser positioning and cutting device for metal processing includes a stable conveying device for conveying sheet metal to the laser cutting device 1, the stable conveying device includes a linear conveyor 2, a plurality of rack mounting seats 3 are installed on the linear conveyor 2, and a plurality of detachable support racks 4 are installed on each rack mounting seat 3. The support rack 4 is used to support the sheet metal. A rack maintenance device is installed under the linear conveyor 2, and the rack maintenance device includes a movable adjustment device 5 fixed on the linear conveyor 2. The movable end of the movable adjustment device 5 is installed with a rack cleaning device 6 and a disassembly device 7. The movable adjustment device 5 is used to move and adjust the positions of the rack cleaning device 6 and the disassembly device 7. The rack cleaning device 6 is used to clean metal slag on the support rack 4, and the disassembly device 7 is used to quickly disassemble the support rack 4.

[0033] When laser cutting a sheet metal part, it is placed horizontally on the support rack 4. The linear conveyor 2 is activated, driving the rack mounting base 3 to move horizontally. The rack mounting base 3, through the support rack 4, moves the sheet metal part synchronously, conveying it to the bottom of the laser cutting device 1. The laser cutting device 1 cuts the sheet metal part once it reaches the designated position. During the cutting process, metal slag may adhere to the surface of the support rack 4. After the sheet metal part is cut, the linear conveyor 2 continues to move the sheet metal part, and the rack mounting base 3 moves synchronously with the support rack 4. When the rack mounting base 3 and the support rack 4 move to the position of the rack maintenance device and maintenance and cleaning of the support rack 4 are required, the movement adjustment device 5 drives the rack cleaning device 6 to the position of the support rack 4. The rack cleaning device 6 effectively cleans the surface of the support rack 4, reducing the amount of metal slag adhering to the support rack 4, thereby extending the service life of the support rack 4 and reducing the cost of using the support rack 4.

[0034] If, after prolonged use, the support rack 4 becomes too damaged by excessive metal slag and becomes unusable, it must be replaced. In this case, the adjustment device 5 switches the positions of the disassembly device 7 and the rack cleaning device 6, which then drives the disassembly device 7 toward the support rack 4. The disassembly device 7 unlocks the rack mounting base 3, allowing the support rack 4 to drop in conjunction with the disassembly device 7. The disassembly device 7 then guides the lowered support rack 4 to the area to be processed, enabling automated disassembly of the support rack 4, effectively reducing replacement steps and improving work efficiency.

[0035] See also Figures 1 to 4 As shown, a plurality of limiting mounting grooves 31 are provided on the rack mounting seat 3, and movable clamping frames 32 are installed at both ends of the limiting mounting grooves 31. The movable clamping frames 32 are slidingly connected to the rack mounting seat 3, and a first spring 34 is installed between the movable clamping frame 32 and the rack mounting seat 3. An unlocking hole 33 is provided at the axial center position of the rack mounting seat 3.

[0036] When installing the support rack 4, the operator applies external force to the movable clamping frame 32, causing it to move to the sides. This causes the movable clamping frame 32 to expand, squeezing the first spring 34 into a compressed state, and subsequently opening the position-limiting mounting slot 31. The operator then inserts the support rack 4 into the position-limiting mounting slot 31. Once the support rack 4 is in place, the external force applied to the movable clamping frame 32 is removed. The first spring 34, under its own elastic restoring force, causes the movable clamping frame 32 to retract and return, thereby position-limiting the support rack 4 within the position-limiting mounting slot 31, enabling convenient installation of the support rack 4.

[0037] An unlocking socket 33 is provided at the axial position of the rack mounting seat 3. When the movable snap-in frame 32 remains retracted, one end of the movable snap-in frame 32 will extend toward the unlocking socket 33. When the support rack 4 has been used for a long time and too much metal slag has accumulated on its surface and it cannot be used any more and needs to be replaced, the disassembly device 7 comes into play. The working end of the disassembly device 7 is inserted into the unlocking socket 33 of the rack mounting seat 3. During the insertion process, the working end of the disassembly device 7 applies a thrust to the movable snap-in frame 32, pushing the movable snap-in frame 32 to expand and move, thereby releasing the limited engagement state between the movable snap-in frame 32 and the support rack 4, and realizing the rapid disassembly and unlocking of the movable snap-in frame 32. At this time, the support rack 4 is no longer constrained by the limited engagement of the movable snap-in frame 32, and falls in cooperation with the disassembly device 7 under the action of gravity or other external forces. The disassembly device 7 guides the falling support rack 4 to the area to be processed, completing the automatic disassembly of the support rack 4.

[0038] See also Figures 1 to 4 As shown, a plug-in base 41 matching the position-limiting installation groove 31 is provided at the bottom of the supporting rack 4 , and a stripping groove 42 is provided on the side of the plug-in base 41 .

[0039] The insertion base 41 is used to be installed in the limiting installation groove 31. The stripping groove 42 of the insertion base 41 is convenient for cooperating with the disassembly device 7 to apply pressure to strip the material for rapid stripping. A plurality of guide teeth are provided on the top of the support rack 4, and the support rack 4 is used to support the sheet metal parts.

[0040] See also Figures 5 to 7 As shown, the rack cleaning device 6 includes a first docking frame 61 installed at the movable end of the movable adjustment device 5, and a plurality of first rack docking holes 611 are provided on the first docking frame 61. A first movable screw slide 62 is installed below the first rack docking hole 611, and a side wall cleaning device 63 and a tooth tip cleaning device 64 are installed at the movable end of the first movable screw slide 62.

[0041] When cleaning and maintenance of the support rack 4 is required, the movable adjustment device 5 is activated, driving the rack cleaning device 6 to move. The rack cleaning device 6 comprises a first docking frame 61 mounted at the movable end of the movable adjustment device 5. The first docking frame 61 is provided with a plurality of first rack docking holes 611. The movable adjustment device 5 drives the first docking frame 61 upward, ensuring that the first rack docking holes 611 precisely mate with the support rack 4. During the docking process, the first rack docking holes 611 effectively restrict the position of the support rack 4, ensuring that the support rack 4 remains stable during subsequent cleaning operations and preventing shaking that could affect the cleaning effect.

[0042] A waste collection box 634 is also mounted at the bottom of the first docking frame 61 to collect metal slag dropped during the cleaning process. After the first docking frame 61 and the support rack 4 are docked and positioned, the first movable screw slide 62 below the first rack docking hole 611 begins operation. The movable end of the first movable screw slide 62 is mounted with a sidewall cleaning device 63 and a tooth tip cleaning device 64. As the first movable screw slide 62 is driven, the sidewall cleaning device 63 and the tooth tip cleaning device 64 move along the support rack 4.

[0043] During movement, the sidewall cleaning device 63 cleans both sides of the support rack 4. Simultaneously, the tooth tip cleaning device 64 cleans the support end of the support rack 4, effectively reducing the accumulation of residual metal slag. Metal slag that falls during the cleaning process falls into the waste collection box 634 for subsequent centralized disposal. The synergistic effect of the sidewall cleaning device 63 and the tooth tip cleaning device 64 reduces the amount of metal slag adhering to the support rack 4, extending the service life of the support rack 4 and reducing operating costs.

[0044] See also Figures 5 to 8 As shown, the side wall cleaning device 63 includes a mounting bracket 631 mounted on the first movable screw slide 62, a synchronous drive device 632 is mounted on the mounting bracket 631, and a plurality of first rotating cleaning wheels 633 are mounted on the synchronous drive device 632. The first rotating cleaning wheels 633 are used to clean both sides of the support rack 4.

[0045] When cleaning and maintenance of the support rack 4 surface is required, the movable adjustment device 5 drives the rack cleaning device 6 to move as a whole, causing the first docking frame 61 to rise and the first rack docking hole 611 to accurately dock with the support rack 4, thereby limiting the position of the support rack 4 and ensuring its stability. At this time, the side wall cleaning device 63, as part of the rack cleaning device 6, is in the operating position corresponding to the support rack 4 along with the first movable screw slide 62. The side wall cleaning device 63 is mounted on the first movable screw slide 62 via the mounting bracket 631. Driven by the first movable screw slide 62, it can move along the length of the support rack 4 to prepare for subsequent cleaning operations.

[0046] The mounting bracket 631 of the sidewall cleaning device 63 is mounted with a synchronous drive device 632. Mounted on this synchronous drive device 632 are multiple first rotating cleaning wheels 633, which are used to clean both sides of the support rack 4. During the cleaning process, the synchronous drive device 632 is activated, driving the multiple first rotating cleaning wheels 633 to rotate synchronously. The outer surfaces of the first rotating cleaning wheels 633 are covered with multiple cleaning strips. As the first rotating cleaning wheels 633 rotate, the cleaning strips come into contact with the metal slag attached to both sides of the support rack 4.

[0047] For metal slag with weak adhesion, the cleaning strip separates the metal slag from the support rack 4 through contact and friction with the metal slag, thereby achieving the purpose of cleaning. For metal slag tightly attached to the support rack 4, the cleaning strip will bend and avoid during the contact process, which can prevent the cleaning strip from applying excessive force to the support rack 4 and prevent deformation of the support rack 4 due to forced cleaning. While ensuring the cleaning effect, it effectively protects the structural integrity of the support rack 4. As the first movable screw slide 62 is continuously driven, the side wall cleaning device 63 moves along the support rack 4, and the multiple first rotating cleaning wheels 633 continuously clean both sides of the support rack 4, reducing the amount of metal slag attached to the side walls of the support rack 4, thereby extending the service life of the support rack 4 and reducing the cost of use.

[0048] The synchronous driving device 632 is a prior art and will not be described in detail here.

[0049] See also Figure 7 and Figure 8 As shown, the tooth tip cleaning device 64 includes a guide rack 646 installed on the first docking frame 61, and the tooth tip cleaning device 64 also includes a horizontal mounting plate 641 installed on the side of the side wall cleaning device 63, and a floating mounting frame 642 is slidably installed on the horizontal mounting plate 641, and a buffer spring 643 is installed between the floating mounting frame 642 and the horizontal mounting plate 641, and an induction roller 644 is installed on the floating mounting frame 642, and the induction roller 644 is in contact with the guide rack 646, and a plurality of second rotating cleaning wheels 645 that move along the tooth tip are also installed on the floating mounting frame 642.

[0050] When cleaning and maintaining the support rack 4, the movable adjustment device 5 drives the rack cleaning device 6, causing the first docking frame 61 to rise and complete docking and positioning with the support rack 4. The first movable screw slide 62 is activated, driving the sidewall cleaning device 63 and tooth tip cleaning device 64 mounted on its movable end to move along the support rack 4. In the tooth tip cleaning device 64, the guide rack 646 is a wavy rack, its undulating profile matching the tooth grooves of the support rack 4. As the guide roller 644 rolls along the wavy path, it drives the second rotating cleaning wheel 645 to float up and down to clean the tooth tips.

[0051] A floating mounting frame 642 is slidably mounted on a horizontal mounting plate 641 mounted on the side of the sidewall cleaning device 63. A buffer spring 643 is installed between the floating mounting frame 642 and the horizontal mounting plate 641. An induced roller 644 is mounted on the floating mounting frame 642, and the induced roller 644 contacts a guide rack 646. When the first movable screw slide 62 drives the tooth tip cleaning device 64 as a whole, the induced roller 644 rolls along the guide rack 646. Because the shape and layout of the guide rack 646 are pre-designed, it effectively controls the movement path of the induced roller 644, ensuring that the induced roller 644 moves along a specific trajectory.

[0052] The floating mounting frame 642 is elastically connected to the horizontal mounting plate 641 via a buffer spring 643. This elastic connection allows the floating mounting frame 642 to elastically move and adjust on the horizontal mounting plate 641. When the guide roller 644 moves along the guide rack 646, the floating mounting frame 642 moves synchronously with the guide roller 644. The buffer spring 643 provides a buffering and adaptive adjustment function, allowing the floating mounting frame 642 to adapt to the movement of the guide roller 644, ensuring that the guide roller 644 always maintains good contact with the guide rack 646 during the movement, thereby ensuring the movement stability of the floating mounting frame 642.

[0053] Multiple second rotating cleaning wheels 645 are also mounted on the floating mounting frame 642. Each second rotating cleaning wheel 645 is driven by an independent first rotating driver 647, enabling rotation. The second rotating cleaning wheels 645 have the same structure as the first rotating cleaning wheels 633. As the floating mounting frame 642 moves with the guide roller 644, it drives the second rotating cleaning wheels 645 along the gaps and top of the support rack 4. The first rotating driver 647 is conventional and will not be described in detail here.

[0054] As the second rotating cleaning wheel 645 rotates, the cleaning strips on the second rotating cleaning wheel 645 come into contact with the metal slag adhering to the gaps and top of the support rack 4. For metal slag with weak adhesion, the cleaning strips separate it from the support rack 4 through friction; for metal slag with strong adhesion, the cleaning strips bend and avoid damage to the support rack 4. The rotation of the second rotating cleaning wheel 645 and its movement along the gaps and top of the support rack 4 effectively clean the metal slag in the gaps and top of the support rack 4, reducing the amount of metal slag remaining at the support end of the support rack 4 and improving the smoothness of the support end, thereby extending the service life of the support rack 4 and reducing its operating costs.

[0055] See also Figures 5 to 9As shown, the disassembly device 7 includes a guide ramp 74 installed at the movable end of the movable adjustment device 5, and a second docking frame 71 is slidably installed on the top of the guide ramp 74. A second spring 72 is installed between the second docking frame 71 and the guide ramp 74. A plurality of second rack docking holes 711 are provided on the second docking frame 71, and a linkage unlocking mechanism 73 for unlocking the rack mounting seat 3 is installed between the second docking frame 71 and the guide ramp 74.

[0056] When support rack 4 becomes unusable due to excessive metal slag accumulation on its surface due to prolonged use, it must be disassembled and replaced. At this point, the movement and adjustment device 5 is activated, switching the positions of rack cleaning device 6 and disassembly device 7, placing disassembly device 7 in the working position. Subsequently, the movement and adjustment device 5 drives the guide ramp 74 upward.

[0057] Because the second docking frame 71 is slidably mounted on top of the guide ramp 74, and a second spring 72 is installed between the second docking frame 71 and the guide ramp 74, as the guide ramp 74 rises, it also drives the second docking frame 71 upward. As the guide ramp 74 and the second docking frame 71 rise, the multiple second rack docking holes 711 on the second docking frame 71 gradually approach the support rack 4. When the second docking frame 71 rises to the appropriate position, the second rack docking holes 711 accurately mate with the support rack 4, providing clearance for the support rack 4 to descend. At the same time, the second docking frame 71 will interfere with the rack mounting base 3 and be unable to rise.

[0058] As the material guide ramp 74 continues to rise, it compresses the second spring 72, causing it to remain compressed. Simultaneously, the material guide ramp 74 drives the working end of the linkage unlocking mechanism 73 to extend upward through the second docking frame 71. The working end of the linkage unlocking mechanism 73 then inserts into the unlocking receptacle 33 of the rack mounting base 3.

[0059] During insertion, the working end of the linkage unlocking mechanism 73 applies a thrust to the movable snap-in frame 32. Because the movable snap-in frame 32 is slidably connected to the rack mounting base 3, and a first spring 34 is installed between the two, the thrust from the working end of the linkage unlocking mechanism 73 causes the movable snap-in frame 32 to overcome the elastic restoring force of the first spring 34 and expand to the sides. As the movable snap-in frame 32 expands, the restricted engagement between the movable snap-in frame 32 and the support rack 4 is gradually released, enabling rapid removal and unlocking of the movable snap-in frame 32.

[0060] When the restricted engagement between the movable engaging frame 32 and the support rack 4 is released, the support rack 4 is no longer constrained by the movable engaging frame 32. At this point, the support rack 4 falls under the action of gravity and lands on the guide ramp 74. The guide ramp 74 has a certain inclination angle, which can guide the falling support rack 4. The guide ramp 74 guides the falling support rack 4 to the processing area, thus completing the automatic removal and material guiding operation of the support rack 4, effectively reducing the replacement steps and improving work efficiency.

[0061] See also Figures 5 to 12 As shown, the linkage unlocking mechanism 73 includes a guide limiter 731 installed on the second docking frame 71, and a longitudinal channel and two transverse channels are provided inside the guide limiter 731. A stripping push block 732 is installed inside each transverse channel, and a third spring 733 is installed between the stripping push block 732 and the transverse channel. A multi-section insert plate 734 is slidably installed inside the longitudinal channel, and the bottom of the multi-section insert plate 734 is fixedly connected to the guide inclined rail 74. The top of the multi-section insert plate 734 is provided with an unlocking bevel 7341, and both sides of the multi-section insert plate 734 are provided with a stripping bevel 7342.

[0062] During the ascending process of the guide ramp 74 , the second rack docking hole 711 of the second docking frame 71 will be driven to dock with the support rack 4 , and at the same time, the second docking frame 71 will conflict with the rack mounting seat 3 and cannot ascend.

[0063] As the guide ramp 74 continues to rise, it compresses the second spring 72, causing it to remain compressed. Simultaneously, the guide ramp 74 drives the multi-segment insert 734 upward through the guide stop 731. The guide stop 731 is mounted on the second docking frame 71 and has a longitudinal channel and two transverse channels within it. The multi-segment insert 734 slides within the longitudinal channel.

[0064] As the multi-segment insert 734 moves upward, the unlocking angle 7341 on its top engages the unlocking receptacle 33 of the rack mounting base 3. Because the movable clamping frame 32 is slidably connected to the rack mounting base 3, and a first spring 34 is installed between the movable clamping frame 32 and the rack mounting base 3, the thrust of the unlocking angle 7341 causes the movable clamping frame 32 to overcome the elastic restoring force of the first spring 34 and expand to the sides. As the movable clamping frame 32 expands, the restricted engagement between the movable clamping frame 32 and the support rack 4 is released, allowing the support rack 4 to fall and remove the material.

[0065] As the multi-segment insert 734 continues to rise, its side stripping angles 7342 exert pressure on the stripping pusher 732. The stripping pusher 732 is mounted within the transverse channel of the guide stop 731, with a third spring 733 installed between the stripping pusher 732 and the transverse channel. Under the pressure of the stripping angles 7342, the stripping pusher 732 overcomes the elastic force of the third spring 733 and moves along the outer side of the transverse channel.

[0066] As the stripping push block 732 extends outward, it contacts the stripping groove 42 of the support rack 4 and applies pressure thereto. Since the restrained engagement between the movable clamping frame 32 and the support rack 4 is now released, the pressure from the push angle causes the support rack 4 to pass through the second rack docking hole 711 and fall onto the guide ramp 74. The guide ramp 74 guides the falling support rack 4 to the area to be processed, enabling rapid stripping of the support rack 4, effectively reducing replacement steps and improving work efficiency.

[0067] See also Figures 9 to 12 As shown, a rotating base plate 741 is rotatably installed inside the material guide inclined rail 74, and a reset push frame 742 is slidably installed on the material guide inclined rail 74. The reset push frame 742 is used to push the rotating base plate 741, and a fourth spring 743 is installed between the bottom of the rotating base plate 741 and the material guide inclined rail 74.

[0068] As the guide ramp 74 rises, it causes the second rack docking hole 711 of the second docking frame 71 to accurately dock with the support rack 4. Simultaneously, the second docking frame 71 will come into contact with the rack mounting base 3 and be unable to rise. As the guide ramp 74 continues to rise, because the second docking frame 71 cannot continue to rise, the guide ramp 74 will continue to rise relative to the second docking frame 71. At this time, the rotating base plate 741 rotatably mounted within the guide ramp 74 will be squeezed by the second docking frame 71. Simultaneously, the reset pusher frame 742 slidably mounted on the guide ramp 74 will also be squeezed, and the fourth spring 743 installed between the bottom of the rotating base plate 741 and the guide ramp 74 will be compressed.

[0069] After the linkage unlocking mechanism 73 unlocks the support rack 4, the support rack 4 is no longer constrained by the movable clamping frame 32 and falls under the action of gravity, falling into the material guide ramp 74 and onto the rotating base plate 741. The rotating base plate 741 is tilted inside the material guide ramp 74, and its tilt angle can be used to guide the support rack 4 to fall to one side and guide the support rack 4 to the area to be processed.

[0070] If the support rack 4 fails to slide smoothly along the rotating base plate 741, after the support rack 4 is removed, the movable adjustment device 5 will drive the disassembly device 7 to descend and reset, and the second docking frame 71 and the guide ramp 74 will simultaneously reset. As the guide ramp 74 resets, the fourth spring 743 is no longer compressed and begins to reset. During this reset, the fourth spring 743 pushes the reset push frame 742 upward, which pushes one side of the rotating base plate 741 upward, effectively increasing the tilt angle of the rotating base plate 741.

[0071] In addition, the rotating base plate 741 will generate impact vibration force when it contacts the material guide ramp 74 during the rotation and resetting process. This vibration force helps to cause the supporting rack 4 that may be stuck on the rotating base plate 741 to slide down smoothly, further improving the effect of guiding the material removal, and ensuring that the supporting rack 4 can fall smoothly into the area to be processed, completing the automatic disassembly and material guiding operations.

[0072] See also Figures 1 to 5 As shown, the movable adjustment device 5 includes a second movable screw slide 51 installed on the side of the linear conveyor 2, the movable end of the second movable screw slide 51 is installed with a linear drive 52, the movable end of the linear drive 52 is installed with a rotating mounting plate 54, and the movable end of the linear drive 52 is also installed with a second rotary drive 53. The output end of the second rotary drive 53 is transmission-connected with the rotating mounting plate 54, and the rotating mounting plate 54 is used to install the rack cleaning device 6 and the disassembly device 7.

[0073] The movable adjustment device 5 also includes a visual detector for real-time identification and detection of the position of the support rack 4 and rack mounting base 3. A second movable screw slide 51 is mounted on the side of the linear conveyor 2, with its movable end connected to a linear actuator 52. The second movable screw slide 51 is controlled based on the position information fed back by the visual detector. The second movable screw slide 51 drives the linear actuator 52 to move horizontally, thereby adjusting the linear actuator 52 to a horizontal position corresponding to the target support rack 4 and rack mounting base 3, providing a basis for subsequent lifting and lowering adjustments.

[0074] After the second movable screw slide 51 adjusts the linear actuator 52 to the appropriate position, the linear actuator 52 drives the second rotary actuator 53 and the rotating mounting plate 54 to move up and down. By controlling the stroke of the linear actuator 52, the vertical height of the rotating mounting plate 54 can be precisely adjusted, allowing the rack cleaning device 6 or removal device 7 mounted on the rotating mounting plate 54 to accurately approach the support rack 4.

[0075] The movable end of the second rotary actuator 53 is connected to a rotating mounting plate 54, which is controlled according to actual needs. The second rotary actuator 53 drives the rotating mounting plate 54 for rotational adjustment. Rotation of the rotating mounting plate 54 changes the position of the rack cleaning device 6 or removal device 7, aligning it with the support rack 4 at a suitable angle for better cleaning or removal operations.

[0076] Specific working principle: When laser cutting a sheet metal part, it is placed horizontally on the support rack 4. The linear conveyor 2 is activated, driving the rack mounting base 3 to move horizontally. The rack mounting base 3, through the support rack 4, moves the sheet metal part synchronously, conveying it to the bottom of the laser cutting device 1. The laser cutting device 1 cuts the sheet metal part once it reaches the designated position. During the cutting process, metal slag may adhere to the surface of the support rack 4. After the sheet metal part is cut, the linear conveyor 2 continues to move the sheet metal part, and the rack mounting base 3 moves synchronously with the support rack 4. When the rack mounting base 3 and the support rack 4 move to the position of the rack maintenance device and maintenance and cleaning of the support rack 4 are required, the movement adjustment device 5 drives the rack cleaning device 6 to the position of the support rack 4. The rack cleaning device 6 effectively cleans the surface of the support rack 4, reducing the amount of metal slag adhering to the support rack 4, thereby extending the service life of the support rack 4 and reducing the cost of using the support rack 4.

[0077] If, after prolonged use, the support rack 4 becomes too damaged by excessive metal slag and becomes unusable, it must be replaced. In this case, the adjustment device 5 switches the positions of the disassembly device 7 and the rack cleaning device 6, which then drives the disassembly device 7 toward the support rack 4. The disassembly device 7 unlocks the rack mounting base 3, allowing the support rack 4 to drop in conjunction with the disassembly device 7. The disassembly device 7 then guides the lowered support rack 4 to the area to be processed, enabling automated disassembly of the support rack 4, effectively reducing replacement steps and improving work efficiency.
