Description

Technical Field

[0001] This invention relates to the field of laser cutting machine feeding technology, and in particular to an automatic feeding structure for laser cutting machines. Background Technology

[0002] A laser cutting machine is a modern processing device that uses a high-energy-density laser beam to locally irradiate a workpiece, causing it to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow blows away the molten material, thus achieving cutting. An automatic feeding structure is a key component for achieving automation and improving production efficiency in laser cutting machines. This structure transports the sheet metal to be processed from the stack to the laser cutting machine's worktable.

[0003] Currently, automated feeding systems typically use vacuum suction cups during material handling. A vacuum generator creates negative pressure to attract and handle individual sheets at a time. However, sheets (especially cold-rolled steel coils, oily surfaces, or stainless steel) easily stick together in the material storage area due to oil film, vacuum suction, static electricity, or high surface flatness. To separate the top and second-top sheets during handling, automated feeding systems usually employ shaking or tapping devices, or use hydraulic mechanisms to warp the edges of the top sheet. However, using shaking or tapping devices can easily cause scratches, dents, or deformation on the sheet surface. Furthermore, the warping method relies on the sheet's toughness and elastic deformation capacity. For high-hardness sheets, edge warping is not feasible, and forceful application can damage the sheet, causing irreversible bending and damage, thus limiting its applicability.

[0004] Therefore, in order to ensure the non-destructive separation of the materials to be processed, this invention provides an automatic feeding structure for laser cutting machines. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic feeding structure for laser cutting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding structure for a laser cutting machine, installed on a crossbeam guide rail, including a main support frame. The main support frame includes a transverse sliding frame that is slidably connected to the crossbeam guide rail by a first driving mechanism and a longitudinal sliding frame that is slidably connected to the transverse sliding frame by a second driving mechanism. The main support frame is provided with a driving component and an auxiliary component, and the driving component is provided with an offset component, and the offset component is provided with multiple pneumatic suction cup components.

[0007] The offset component includes a support assembly disposed on the driving component, and four offset components are disposed on the support assembly. The auxiliary component includes an auxiliary support frame disposed on the longitudinal sliding frame, and four brackets are disposed on the auxiliary support frame, with auxiliary components disposed on the brackets.

[0008] The offset component rotates and pushes the topmost plate to be fed in the circumferential direction, and the auxiliary component assists in separating the topmost plate and the next-upper plate during the pushing process. The pneumatic suction cup component, the offset component, and the auxiliary component work together to perform the feeding and separation operation by combining mechanical rotation offset and pneumatic methods.

[0009] In the above-mentioned automatic feeding structure for a laser cutting machine, the driving component includes a motor, and the motor is mounted on the bottom wall of the longitudinal sliding frame. A support base is detachably mounted on the bottom wall of the output end of the motor.

[0010] In the above-mentioned automatic feeding structure for a laser cutting machine, the top wall of the support base is symmetrically and fixedly connected with arc-shaped sliders, and the top of the sliders is circumferentially slidably connected to the bottom wall of the longitudinal sliding frame.

[0011] In the above-mentioned automatic feeding structure for a laser cutting machine, the support component includes an inner frame, and the bottom wall of the support base is fixedly connected to the inner frame. The inner frame includes a plurality of front-to-back oriented rods evenly distributed from left to right and a plurality of left-to-right oriented rods evenly fixedly connected from front to back to the top walls of the plurality of front-to-back oriented rods. The side walls of the front-to-back oriented rods are jointly fixedly connected to the outer frame.

[0012] In the above-mentioned automatic feeding structure for a laser cutting machine, the offset component includes an adjustment frame. The left rear, rear right, right front, and front left parts of the outer frame are all slidably connected to the adjustment frame. The adjustment frame includes a horizontal section that is parallel to the bottom of the outer frame, and two vertical sections that are symmetrically fixed to the top wall of the horizontal section and slide vertically through the outer frame.

[0013] In the above-mentioned automatic feeding structure for a laser cutting machine, multiple motors are installed on the top wall of the outer frame via an inverted U-shaped frame. The motors correspond to the adjustment frame, and the bottom wall of the output end of the motors is fixed with a screw threaded to the horizontal section of the outer frame and the adjustment frame.

[0014] In the aforementioned automatic feeding structure for a laser cutting machine, multiple pneumatic suction cup components are uniformly fixedly installed on the front and rear facing rods of the inner frame, and pushing strips are fixedly connected to the side of the adjustment frame near the pneumatic suction cup components.

[0015] In the above-mentioned automatic feeding structure for a laser cutting machine, the longitudinal sliding frame sidewall is slidably connected to an auxiliary support frame via a drive mechanism. The auxiliary support frame is located above the outer frame, and the left front, rear left, right rear, and front right sidewalls of the auxiliary support frame are all fixedly connected to brackets.

[0016] In the above-mentioned automatic feeding structure for a laser cutting machine, the auxiliary components include a wedge, and the wedge and a high-pressure air nozzle are fixedly connected to the lower part of the bracket near the pneumatic suction cup component. The high-pressure air nozzle is located below the wedge and is connected to an external air pump through a ventilation pipe.

[0017] In the aforementioned automatic feeding structure for a laser cutting machine, the top wall of the wedge is inclined, and the edges of the wedge are all chamfered. The top height of the wedge is lower than the bottom height of the pneumatic suction cup component.

[0018] Compared with existing technologies, the advantages of this invention are: 1. By combining rotational offset and pneumatic methods, and utilizing shearing force, mechanical peeling force and pneumatic pressure, static friction, vacuum adsorption and oil film work together to avoid scratches, dents or deformations on the surface of the board for different types of adhesion; and it is more reliable and has wider adaptability than a single mechanical warping method.

[0019] 2. The four pushing strips located at the left rear, rear right, right front, and front left of the top layer of the board move simultaneously, pushing the top layer of the board in four directions around the circumference, changing from an overlapping state to a partially staggered state; by mechanically rotating and shifting, the shear force between the two layers of the board is destroyed, fundamentally avoiding scratches, dents, or deformations on the board surface caused by separation due to violent impacts or vibrations.

[0020] 3. Utilize the adsorption force, support force, and air pressure of the pneumatic suction cup components to overcome local adsorption forces, such as vacuum adsorption and oil film tension, and assist the offset components in separating the plates to ensure a non-destructive separation process; the pneumatic suction cup components adsorb the steel plates, and the four corners of the top plate are pushed by the pushing strips while being relatively lifted by the wedges. Dust is generated between the top plate and the next top plate, and at the same time, high-pressure jet nozzles cooperate to spray high-pressure gas from the corresponding gaps into the gaps between the two plates. The gas quickly fills the gaps and separates the plates. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 3An automatic feeding structure for a laser cutting machine is installed on an external crossbeam guide rail. It includes a main support frame 1. The main support frame 1 includes a transverse sliding frame that is slidably connected to the crossbeam guide rail by a drive mechanism 1 and a longitudinal sliding frame that is slidably connected to the transverse sliding frame by a drive mechanism 2. The main support frame 1 is provided with a drive component 2 and an auxiliary component 5. The drive component 2 is provided with an offset component 3. The offset component 3 is provided with multiple pneumatic suction cup components 4 (existing mature technology, which will not be described in detail here).

[0036] The working object of this invention is a steel plate with a certain hardness and a thickness between 10 mm and 30 mm. Multiple layers of plates to be processed are stacked on the material rack. The horizontal sliding frame is moved to the top of the plate by the second drive mechanism, and the vertical sliding frame is moved down to approach the plate by the first drive mechanism (both the first and second drive mechanisms are servo motors with gears and racks, not shown in the figure, and existing mature technologies will not be described in detail here).

[0037] The main support frame 1 drives the offset component 3 to move downwards, and the pneumatic suction cup component 4 adsorbs the uppermost material to be processed. The driving component 2 drives the offset component 3 to rotate, and the offset component 3 pushes the uppermost material to be processed in a circumferential direction to generate a positional offset. The uppermost material to be processed and the next uppermost material to be processed change from an overlapping state to a partially intersecting state. The auxiliary component 5 creates a gap between the two materials while they are intersecting, and uses air pressure to overcome the remaining local adsorption force. The main support frame 1 drives the offset component 3 to move upwards until the two materials are completely separated and leave the material rack, and are fed to the laser cutting machine.

[0038] Reference Figures 1 to 3 The driving component 2 includes a motor 21. The motor 21 is mounted on the bottom wall of the longitudinal sliding frame. A support base 22 is detachably mounted on the bottom wall of the output end of the motor 21. An arc-shaped slider 23 is symmetrically fixedly connected to the top wall of the support base 22. The top of the slider 23 is circumferentially slidably connected to the bottom wall of the longitudinal sliding frame.

[0039] Reference Figures 1 to 3 The offset component 3 includes a support component 31 disposed on the drive component 2, and four offset components 32 disposed on the support component 31. The support component 31 includes an inner frame 311, and the bottom wall of the support base 22 is fixedly connected to the inner frame 311. The inner frame 311 includes a plurality of front-to-back oriented rods evenly distributed from left to right and a plurality of left-to-right oriented rods evenly fixedly connected from front to back to the top wall of the plurality of front-to-back oriented rods. The side walls of the front-to-back oriented rods are jointly fixedly connected to an outer frame 312.

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 11 The offset component 32 includes an adjustment frame 321. The left rear, rear right, right front, and front left parts of the outer frame 312 are all slidably connected to the adjustment frame 321. The adjustment frame 321 includes a horizontal section parallel to the bottom of the outer frame 312, and two vertical sections symmetrically fixed to the top wall of the horizontal section and sliding through the outer frame 312. The top wall of the outer frame 312 is equipped with multiple motors 323 via an inverted U-shaped frame. The motors 323 correspond to the adjustment frame 321. The bottom wall of the output end of the motors 323 is fixed with a screw 322 threaded to the outer frame 312 and the horizontal section of the adjustment frame 321. Multiple pneumatic suction cup components 4 are evenly fixed on the front and rear facing rods of the inner frame 311. Pushing strips 324 are fixedly connected to the side of the adjustment frame 321 near the pneumatic suction cup components 4.

[0041] Reference Figure 1 , Figure 5 The auxiliary component 5 includes an auxiliary support frame 51 mounted on a longitudinal sliding frame. The auxiliary support frame 51 is provided with four brackets 52, and the brackets 52 are provided with auxiliary components 53. The auxiliary support frame 51 is slidably connected to the side wall of the longitudinal sliding frame through a drive mechanism three (the drive mechanism three is a high-resolution servo motor and a small-pitch high-precision micron-level lead screw, not shown in the figure, and existing mature technologies will not be described in detail here). The auxiliary support frame 51 is located above the outer frame 312. The left front, rear left, right rear, and front right side walls of the auxiliary support frame 51 are all fixedly connected with brackets 52.

[0042] Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 The auxiliary component 53 includes a wedge 531. The wedge 531 and the high-pressure nozzle 532 are fixedly connected to the lower part of the bracket 52 near the side of the pneumatic suction cup component 4. The high-pressure nozzle 532 is located below the wedge 531 and is connected to an external air pump (not shown in the figure) through a ventilation pipe (not shown in the figure). The top wall of the wedge 531 is inclined, and the edges of the wedge 531 are all chamfered. The top height of the wedge 531 is lower than the bottom height of the pneumatic suction cup component 4.

[0043] The longitudinally moving carriage drives the driving component 2 and the offset component 3 to move downwards directly above the plate until the bottom wall of the suction cup component 4 of the pneumatic suction cup component 4 is in close contact with the topmost plate. The pneumatic suction cup component 4 uses the air pressure difference to generate suction force to adsorb the steel plate (e.g., Figure 7 and Figure 9 As shown), at this time, the push bar 324 is located on the side of the uppermost plate, and the wedge block 531 is located on the side of the next uppermost plate (as shown). Figure 7 (As shown).

[0044] The heights of the push bar 324 and wedge block 531 can be adjusted according to the thickness of the uppermost plate, as follows: The bottom output end of motor 323 rotates, driving the lead screw 322 to rotate. The lead screw 322 drives the horizontal section of the adjusting frame 321 to adjust up and down. The vertical section of the adjusting frame 321 slides up and down on the outer frame 312 to adapt to changes in the position of the horizontal section of the adjusting frame 321. The up and down adjustment of the adjusting frame 321 drives the push bar 324 to make fine adjustments up and down. The height of the auxiliary support frame 51 is finely adjusted up and down by the drive mechanism 3.

[0045] It should be noted that motor 323 is a high-resolution servo motor, and lead screw 322 is a small-pitch, high-precision micron-level screw, ensuring precise control of the push bar 324 for up-and-down fine-tuning, so that the push bar 324 is aligned with the middle of the side wall of the steel plate with a thickness between 10 mm and 30 mm; drive mechanism 3 is a high-resolution servo motor and a small-pitch, high-precision micron-level lead screw working together to drive and adjust the height of the auxiliary support frame 51. The auxiliary support frame 51 drives the bracket 52 and auxiliary components 53 to move until the wedge block 531 is aligned with the next upper layer of plate; the above adjustment only needs to be adjusted once when changing to different batches or different plate thicknesses.

[0046] After the push bar 324 is aligned with the middle of the uppermost plate, it rotates clockwise through the bottom output end of motor 21, driving the support base 22 and support assembly 31 to rotate. The slider 23 slides circumferentially on the bottom wall of the longitudinal sliding frame to enhance the balance and stability during sliding.

[0047] It should be noted that Motor 121 is a high-torque motor, which can overcome large resistance to start and run, so as to ensure that the output torque is greater than the resistance torque and static friction between the upper and lower plates when rotating.

[0048] The four pushing strips 324 located at the rear left, rear right, front right, and front left of the topmost plate simultaneously shift, pushing the topmost plate from four directions. The next-upper plate is restrained laterally by the wedge block 531 and does not move accordingly. The topmost plate experiences a positional shift, and the overlapping state between the topmost and next-upper plates changes to a partially interlaced state (e.g., ...). Figure 7 and Figure 8 As shown in the diagram, the static friction between the topmost and next-uppermost sheets of material is strongest in the shear direction. Once rotation begins, this static friction is broken, and the adhesion loosens. By mechanically rotating and shifting the material, the shear force between the two layers is disrupted, fundamentally preventing scratches, dents, or deformations on the sheet surface caused by severe impacts or vibrations.

[0049] The top wall of wedge 531 is inclined. As the uppermost plate slowly moves, it gradually comes into contact with the top surface of the main support frame 1 of bracket 52. The four corners of the uppermost plate are simultaneously lifted by wedge 531, creating a dust gap between the uppermost and next-upper plates. At the same time, high-pressure jet nozzle 532 sprays high-pressure gas from the corresponding gap into the space between the two plates. The gas can quickly fill the gap, using air pressure to overcome the remaining local adsorption forces such as vacuum adsorption and oil film tension. The longitudinal sliding frame drives the whole structure to move upward, jointly performing a rapid separation operation. By combining rotational offset and pneumatic methods, and utilizing shear force, mechanical peeling force, and pneumatic pressure, static friction, vacuum adsorption, and oil film work together to address different types of adhesion causes. This method is more reliable and has wider adaptability than a single mechanical warping method.

[0050] It is important to note that the tilt angle of the top wall of wedge 531 should be between three and eight degrees. The chamfering treatment on the sidewall of wedge 531 that contacts the plate ensures a high success rate of separation while reducing the risk of damage to the plate. Furthermore, the rotational speed of motor 21 and wedge 531, the shape of wedge 531, the insertion depth of wedge 531, the pressure and timing of air blowing are all results obtained by those skilled in the art through numerous experiments, and are precisely controlled by a PLC during use.

[0051] During the movement toward the laser cutting machine, the wedge 531 provides partial support to the uppermost plate, which helps to enhance stability during the movement. When loading the material onto the laser cutting machine, the motor 21 rotates counterclockwise to drive the offset component 3, the pneumatic suction cup component 4, and the plate to rotate and reset. The plate returns to the upright position from the offset state and is unloaded after being unobstructed by the wedge 531.

[0052] In this invention, the offset component 32 rotates and pushes the topmost plate to be fed in the circumferential direction, while the auxiliary component 53 assists in separating the topmost and next-uppermost plates during the pushing process. The pneumatic suction cup component 4, the offset component 32, and the auxiliary component 53 work together to perform the feeding and separation operation through a combination of mechanical rotation offset and pneumatic methods. Although this invention increases the cost of equipment by adding the offset component 32 and the auxiliary component 5 compared to the prior art, it utilizes shearing force, mechanical peeling force, and pneumatic pressure to address different types of adhesion causes (static friction, vacuum adsorption, oil film), thus avoiding scratches, dents, or deformations on the plate surface. Furthermore, it is more reliable and adaptable than a single mechanical warping method, enabling rapid and non-destructive separation of two plates with a certain hardness that are adhered to each other. From a long-term economic perspective, the increased equipment cost of this invention compared to the prior art is negligible.
