[0061] The present invention will now be described in detail with reference to the accompanying drawings.

[0062] like Figures 1 to 4 As shown, the present invention provides a rotary cutting mechanism, which includes a machine base 1, a laser cutting device 2, a rotary conveying device 3, and a conveying device 4.

[0063] The machine base 1 is provided with a processing station 11 and a loading / unloading station 12; the laser cutting device 2 is located directly above the processing station 11; the machine base 1 is provided with a first positioning fixture 13 and a second positioning fixture 14 corresponding to the conveying path of the conveying device 4; the rotary conveying device 3 is rotatably disposed on the machine base 1 and is used to convey materials between the loading / unloading station 12 and the processing station 11; the conveying device 4 is disposed on the machine base 1 and is used to sequentially convey materials between the external loading line, the first positioning fixture 13 and the loading / unloading station 12, and between the loading / unloading station 12, the second positioning fixture 14 and the external unloading line.

[0064] Specifically, by positioning the laser cutting device 2 directly above the processing station 11 and using a vertical alignment installation method, the laser beam path forms the shortest vertical distance with the material plane, reducing beam scattering and focal length errors. This improves cutting accuracy and reduces the width of the heat-affected zone.

[0065] The rotary conveyor 3 directly rotates the material from the loading / unloading station 12 to the processing station 11, avoiding the cumulative error of the multi-axis motion of the traditional robotic arm.

[0066] The first positioning fixture 13 and the second positioning fixture 14 are used for pre-positioning of loading and re-inspection of unloading, respectively. The material positioning accuracy is improved by compensating for material offset through two positioning operations.

[0067] When the processing station 11 is cutting, the loading and unloading station 12 can simultaneously change materials, improving the equipment utilization rate. The single conveyor device 4 integrates the loading, positioning, and unloading paths to form an integrated conveyor device 4, reducing the number of drive components, reducing the equipment footprint, and lowering the vibration amplitude.

[0068] In operation, the laser cutting device 2 cuts the material carried by the rotary conveyor 3 at the processing station 11 according to a predetermined setting. The rotary conveyor 3 transfers the processed material to the loading / unloading station 12 and then stops. The conveyor 4 transfers the unprocessed material from the external loading line to the first positioning fixture 13 for pre-positioning. Simultaneously, the conveyor 4 at the loading / unloading station 12 transfers the processed material from the rotary conveyor 3 to the second positioning fixture 14 for verification positioning. After pre-positioning is completed by the first positioning fixture 13, the second... The two positioning fixtures 14 complete the verification and positioning. The conveying device 4 conveys the pre-positioned unprocessed material to the rotary conveyor 3, which is stopped at the loading and unloading station 12. The rotary conveyor 3 receives the pre-positioned unprocessed material and conveys it to the processing station 11 for the laser cutting device 2 to perform cutting processing. At the same time, the conveying device 4 conveys the verified and positioned processed material to the external unloading line. In this way, the synchronous loading, pre-positioning, laser cutting, verification and positioning, and unloading of materials are repeatedly realized, which solves the problems of large positioning error, low efficiency and complex structure of traditional equipment.

[0069] like Figure 2 As shown, the laser cutting device 2 in this embodiment includes a laser cutting unit 21, a detection device 22, a detection driver 23, and a dust removal assembly 24. The laser cutting unit 21 is a picosecond or femtosecond laser cutter. The detection driver 23 is a servo motor and ball screw drive module or a linear motor.

[0070] The laser cutting unit 21 is disposed on the machine base 1 and located directly above the processing station 11; the detection device 22 is disposed below the laser cutting unit 21 and is used to acquire an image of the material to be processed; the detection driver 23 is fixed to the machine base 1 and is used to drive the detection device 22 to move; one end of the dust removal component 24 is connected to the machine base 1, and the other end of the dust removal component 24 is disposed between the laser cutting unit 21 and the rotary conveyor 3.

[0071] Specifically, the laser cutting unit 21 is vertically mounted directly above the processing station 11 to reduce beam scattering and focal length deviation.

[0072] The detection device 22 is an optical detector. A high-resolution optical detector (such as a CCD camera) is integrated below the laser cutting unit 21 to acquire images of the material surface in real time, which facilitates the detection of untreated materials or processed materials.

[0073] The detection device 22 is displaced by the detection driver 23, which facilitates the adjustment of the position of the detection device 22 relative to the material or the laser cutting unit 21, and avoids affecting the cutting operation of the laser cutting unit 21 when acquiring the image of the material surface.

[0074] A dust removal component 24 is installed between the laser cutting unit 21 and the rotary conveyor 3. The dust removal component 24 uses negative pressure to extract dust and debris generated during cutting. This prevents dust from adhering to the material surface or the laser cutting unit 21, improving the stability of cutting quality; reducing internal contamination of the equipment; and extending the maintenance cycle.

[0075] like Figure 3 As shown, the dust removal assembly 24 in this embodiment includes a support frame 241, a processing hood frame 242, a dust suction pipe 243, and an air blowing component 244; the support frame 241 is fixed to the machine base 1 and is used to support the processing hood frame 242; the processing hood frame 242 is provided with a processing port 245; the dust suction pipe 243 is connected to the processing hood frame 242; the air blowing component 244 is disposed on one side of the processing hood frame 242 opposite to the dust suction pipe 243.

[0076] Specifically, the processing cover 242 is rigidly connected to the machine base 1 through a rigid support structure (such as an aluminum alloy frame), forming a spatial isolation zone inside the processing cover 242 to block the outward diffusion path of dust. This eliminates the interference of equipment vibration on the dust collection component 24, improving the stability of dust collection; the modular design facilitates quick disassembly and maintenance.

[0077] The processing port 245 provides a vertical channel for laser cutting (the aperture is slightly larger than the laser spot diameter), while limiting the dust diffusion range and forming a semi-enclosed dust collection space. The dust escape rate is lower than that of traditional open structures.

[0078] The suction pipe 243 is connected to the side or top of the processing hood 242. It generates a negative pressure of ≥500Pa through a centrifugal fan to directionally extract the dust generated during cutting. The dust collection efficiency is ≥98%, preventing dust from adhering to materials or the laser lens. The suction pipe 243 can be connected to an external centralized dust removal system to reduce the risk of internal contamination of the equipment.

[0079] An air blowing component 244 (such as a compressed air nozzle) is positioned on the opposite side of the suction pipe 243, forming a unidirectional airflow (wind speed ≥10m / s) that directs suspended dust to the suction port of the suction pipe 243. This eliminates dust eddy retention within the processing hood frame 242, reducing dust removal dead zones by 90%; the synergistic effect of the airflow increases dust particle aggregation by 40%, extending the lifespan of the filtration system.

[0080] like Figure 4As shown, the conveying device 4 in this embodiment includes a conveying frame 41, a synchronous driver 42, a loading clamp 43, a unloading clamp 44, a first optical detector 45, and a second optical detector 46. The conveying frame 41 is fixed to the machine base 1. The synchronous driver 42 is disposed on the conveying frame 41 and is used to drive the loading clamp 43 and the unloading clamp 44 to move simultaneously. The first optical detector 45 is fixed to the loading clamp 43 and is used to acquire images of unprocessed materials. The second optical detector 46 is fixed to the unloading clamp 44 and is used to acquire images of processed materials.

[0081] Specifically, the conveyor frame 41 integrates the overall structure of the conveyor device 4 with the machine base 1 through rigid connections (such as bolting or welding), forming a stable mechanical support foundation and eliminating displacement deviations caused by independent installation of multiple modules.

[0082] The synchronous driver 42 uses a single-axis synchronous belt or linear motor to drive the loading clamp 43 and unloading clamp 44 in a dual-slider common rail design, achieving synchronous movement of loading and unloading with perfect timing matching. The operation cycle of the loading clamp 43 and unloading clamp 44 is shortened by 50% (from 2 seconds / cycle to 1 second / cycle); avoiding the asynchronous error of traditional dual drivers, the material handover positioning accuracy is improved to ±0.02mm.

[0083] The first optical detector 45 is fixed to the loading clamp 43. The first optical detector 45 is a CCD camera, so that the loading clamp 43 integrates a high-resolution CCD camera to capture the surface image of the unprocessed material (such as scratches and foreign objects) in real time, so as to facilitate the early rejection of defective products (identification accuracy ±0.01mm) and avoid ineffective processing.

[0084] The second optical inspection instrument 46 is fixed to the unloading clamp 44. The second optical inspection instrument 46 is an infrared or laser scanner, which facilitates 3D morphological detection of the cut edge of the processed material (such as burr height and chipped edge size), and facilitates accurate positioning of the material cutting defects in subsequent material selection and inspection processes.

[0085] like Figure 4 As shown, in this embodiment, both the loading clamp 43 and the unloading clamp 44 include a lifting driver 431, a clamping or releasing driver 432, a gripper 433, and a vacuum suction cup 434. The lifting driver 431 can be a drive module combining a servo motor and a ball screw, a cylinder, or an electric cylinder. The clamping or releasing driver 432 is a pneumatic slide, an electric slide, a bidirectional cylinder, or a linear motor. The first optical inspection instrument 45 and the second optical inspection instrument 46 are both laser displacement sensors or CCD cameras.

[0086] The lifting driver 431 is fixed to the synchronous driver 42 and is used to drive the clamping or releasing driver 432 to lift. The lifting driver 431 is rigidly connected to the moving shaft of the synchronous driver 42 to realize the synchronous control of the vertical lifting and horizontal movement of the gripper 433.

[0087] The number of grippers 433 is two, and the two grippers 433 are respectively slidably connected to the two sides of the gripping or releasing driver 432. The gripping or releasing driver 432 is used to drive the two grippers 433 to move closer to each other or further away from each other. The gripping driver drives the two grippers 433 to slide in both directions, so that the two grippers 433 can move closer to each other to grip the material and move further away from each other to release the material, which can adapt to different materials.

[0088] The vacuum suction cup 434 is fixed to the bottom of the clamping or releasing driver 432 and is used to hold materials. When the gripper 433 closes, the vacuum suction cup 434 adsorbs the material through negative pressure, forming a double fixation of gripper 433 and vacuum adsorption, which improves the anti-vibration and offset capability.

[0089] The first optical detector 45 is fixed to the lifting driver 431 of the loading clamp 43; the second optical detector 46 is fixed to the lifting driver 431 of the unloading clamp 44. The first optical detector 45 and the second optical detector 46 move synchronously with the lifting driver 431 to acquire the image of the material surface during the material lifting process, which facilitates the subsequent inspection work.

[0090] like Figure 4 As shown, the clamping or releasing driver 432 in this embodiment is provided with a driving block 4321. There are two driving blocks 4321. The clamping or releasing is used to drive the two driving blocks 4321 to move closer or further away from each other. The two driving blocks 4321 move synchronously in opposite directions through the clamping or releasing driver 432. The driving path is symmetrical and the force is balanced, eliminating the eccentric torque of unilateral driving.

[0091] The gripper 433 includes a gripping rod 4331 and a support block 4332. The gripping rod 4331 slides along the vertical direction of the drive block 4321 and moves as the two drive blocks 4321 move closer or further apart. After the gripper 433 grips the material, the material can slide along the vertical direction of the drive block 4321 with the gripping rod 4331. This avoids hard contact between the material and the carrier (such as the first positioning fixture 13, the second positioning fixture 14, or the rotary conveyor 3) when the material is released. The impact force is dissipated by sliding along the vertical direction of the drive block 4321.

[0092] The support block 4332 is disposed on the side of the clamping rod frame 4331 facing the clamping or releasing driver 432 and is used to support the material. The support block 4332 is made of a soft material (such as silicone or polyurethane) that conforms to the edge of the material, providing surface contact support during clamping and dispersing local pressure.

[0093] like Figure 2 As shown, the rotary conveying device 3 in this embodiment includes a rotary frame 31, a material holding tray 32, and a rotary driver 33. The rotary frame 31 is rotatably connected to the machine base 1. The material holding tray 32 is disposed on the rotary frame 31 and is used to fix the material. The rotary driver 33 drives the rotary frame 31 and the machine base 1 to rotate.

[0094] Specifically, the rotating frame 31 is rotatably connected to the machine base 1 through high-precision bearings (such as crossed roller bearings), and the rotation axis is precisely aligned with the spatial position of the processing station 11 and the loading / unloading station 12 to ensure the shortest rotation path.

[0095] The solid material tray 32 uses vacuum adsorption or electrostatic adsorption technology to stabilize the material during rotation, avoiding slippage or vibration displacement.

[0096] The rotary driver 33 uses a direct drive servo motor (DD motor) or a harmonic geared motor to drive the rotary frame 31 and the machine base 1 to rotate, meeting the micron-level cutting requirements.

[0097] like Figure 2 As shown, the material tray 32 in this embodiment includes a negative pressure suction cup 321, and a material-bearing protrusion 322 is provided on the top of the negative pressure suction cup 321; the material-bearing protrusion 322 is provided on the top of the negative pressure suction cup 321; and a relief groove 323 is provided at the connection between the material-bearing protrusion 322 and the negative pressure suction cup 321 to avoid the gripper 433.

[0098] Specifically, the negative pressure suction cup 321 generates negative pressure (-50kPa to -90kPa) through a vacuum pump, uses adsorption force to fix the bottom of the material, and at the same time distributes the adsorption force evenly through a porous structure (pore diameter 0.1-0.5mm) to avoid local stress concentration, so that the material is fixed on the solid material plate 32 and the material fixation deviation is reduced.

[0099] Preferably, the support boss 322 is made of an elastic material (such as silicone or polyurethane) to disperse pressure.

[0100] A U-shaped or V-shaped clearance groove 323 is provided on the edge of the suction cup to provide physical space for the gripper 433 to perform gripping or releasing actions, thereby avoiding interference between the gripper 433 and the suction cup.

[0101] like Figure 2As shown, in this embodiment, both the first positioning fixture 13 and the second positioning fixture 14 include a support part 141, a bearing part 142 and a positioning part 143; the support part 141 is fixed to the machine base 1; the bearing part 142 is disposed at the top of the support part 141; and the positioning part 143 is disposed at the edge of the support part 141.

[0102] Specifically, the support 141 is integrated with the machine base 1 through a rigid connection (such as bolting or welding) to form a stable mechanical reference surface and eliminate the interference of external vibration on the positioning process.

[0103] The bearing part 142 is made of a low-friction coefficient material (such as Teflon coating or air-bearing guide rail), and the material is fixed by planar support or vacuum adsorption to reduce the frictional resistance of the contact surface.

[0104] The positioning part 143 is provided at the edge of the support part 141 to perform lateral limiting after the material is placed in order to correct the positional deviation.

[0105] like Figure 2 As shown, the supporting part 142 in this embodiment is provided with a clearance groove 144 to facilitate the clamping or releasing of materials by the conveying device 4. Specifically, a clearance groove 144 (such as a U-shaped or rectangular groove) matching the movement trajectory of the gripper 433 of the conveying device 4 is formed on the surface of the supporting part 142. This eliminates contact interference between the gripper 433 and the supporting part 142 through physical space avoidance, while retaining a stable support area at the bottom of the material. This avoids clamping interference and improves loading and unloading efficiency.
