Description

Technical Field

[0001] This invention relates to the field of laser processing technology, specifically to a TPF laser cutting production line and production process. Background Technology

[0002] TPF (Thin Functional Film) refers to roll-shaped functional materials based on materials such as PET and COP. It is widely used in display panel manufacturing, for example, as Top Protective Film for process protection and Touch Panel Film for touch sensing. While these two types of materials differ in specific functions and applications, they share certain common processing requirements: both require cutting the entire roll of substrate into individual sheets, followed by precise shape cutting and perforation according to product specifications. This necessitates high levels of processing precision, cleanliness, and production efficiency.

[0003] The existing TPF processing production line specifically refers to an optical film roll cutting system and method disclosed in CN114733799B, which includes a winding device, an AOI device, and a cutting device. The winding device has a winding machine and an encoder. The winding machine sequentially winds the optical film roll to the AOI device and the cutting device. The encoder is used to detect the winding code of the optical film roll. The AOI device has a line scan camera for detecting defects in the film roll. The cutting device has a cutting blade for cutting the optical film roll into cut sheets.

[0004] However, this plan still has the following shortcomings: In this solution, the encoder serves only as an internal length measuring element. The detected roll code is not physically printed onto the roll surface. The line scan camera is only used to identify defect marks already applied in the previous process, rather than performing real-time defect detection and marking. When the roll is cut into individual sheets by the cutting tool, the precise position information of the sheet in the original roll coordinate system (i.e., the code recorded by the encoder) is lost, making full-process traceability impossible through readable markings on the finished product. This is especially problematic for OLED top protective film (TPF), where quality abnormalities (such as microcrystalline spots and invisible scratches) are often not visible to the naked eye. Without precise marking before cutting, defective products can easily flow into expensive downstream processes, resulting in huge panel scrap losses.

[0005] Furthermore, the cutting device in this solution uses mechanical cutting tools, which is a single-stage physical cutting process. It can only cut the roll material into rough sheets and cannot continuously complete fine finishing processes such as irregular cutting or micro-hole processing on the same production line. To achieve complete forming processing, additional laser processes and equipment are still required. This leads to process interruptions and material turnover. For heat-sensitive materials such as TPF, if the stress generated by mechanical cutting and the heat effect generated by laser precision cutting are concentrated in a single stage, it can easily cause the sheet to shrink or warp, affecting the dimensional stability of the final product.

[0006] Therefore, this invention proposes a TPF laser cutting production line and production process. Summary of the Invention

[0007] This invention provides a TPF laser cutting production line and process to solve the problems mentioned in the background art.

[0008] The objective of this invention is achieved through the following means: A TPF laser cutting production line includes, in sequence along the conveying direction: a roll material feeding module, an AOI coding module, a laser slicing module, a semi-finished product transfer module, a laser cutting module, a finished product picking module, and a receiving system; The AOI coding module is used to detect and mark the surface of the roll material before it enters the laser slicing module. The laser slicing module is used to cut the inkjet-printed roll material into single semi-finished products. The semi-finished product transfer module is used to receive and carry the single semi-finished product output by the laser slicing module, and to transport the single semi-finished product to the laser cutting module. The finished product picking module is used to receive and carry the finished products output by the laser cutting module, and to transport the finished products to the receiving system.

[0009] As a preferred solution for a TPF laser cutting production line, the AOI coding module includes a bracket, a vertical detection component, a lateral detection component, and a coding component. The bracket is equipped with a dust-adhesive roller at one end near the roll material feeding module, and a guide roller for conveying the roll material is provided inside the bracket. A pressure roller component is provided at one end of the bracket near the laser slicing module.

[0010] As a preferred embodiment of a TPF laser cutting production line, the laser slicing module includes a sheet conveyor belt and a laser slicing assembly disposed on the sheet conveyor belt, wherein the laser slicing assembly is disposed at one end of the sheet conveyor belt near the AOI inkjet printing module.

[0011] As a preferred solution for a TPF laser cutting production line, the laser cutting module includes two sets of laser processing units, which are arranged in a front-to-back or side-by-side along the conveying direction.

[0012] As a preferred embodiment of a TPF laser cutting production line, the laser processing unit includes a worktable and a cutting component that can move horizontally on the worktable via a moving module. The worktable is provided with a fixing component for fixing the single semi-finished product.

[0013] As a preferred solution for a TPF laser cutting production line, the semi-finished product transfer module and the finished product pickup module alternately cooperate with the two sets of laser processing units to achieve continuous processing.

[0014] As a preferred solution for a TPF laser cutting production line, both the semi-finished product transfer module and the finished product picking module are robotic arms, and the output end of the robotic arm is equipped with a vacuum suction cup assembly.

[0015] As a preferred solution for a TPF laser cutting production line, the vacuum chuck assembly is equipped with a vision inspection component.

[0016] As a preferred solution for a TPF laser cutting production line, the receiving system includes a good product receiving area, a waste area, and a defective product temporary storage area. The good product receiving area is used to receive qualified finished products conveyed by the finished product picking module. The waste area is used to collect scrap materials generated during processing. The defective product temporary storage area is used to temporarily store defective products that do not meet the preset standards for subsequent re-inspection or processing.

[0017] A production process based on the TPF laser cutting production line includes the following steps: S1. Feeding and Inspection / Coding: The roll material is fed out by the roll material feeding module and inspected and marked by the AOI coding module; S2. Laser Slicing: The laser slicing module cuts the roll material into single semi-finished pieces; S3. Semi-finished product transfer: The semi-finished product transfer module transfers single pieces of semi-finished products from the laser slicing module to the processing station of the laser cutting module. S4. Laser cutting: The laser cutting module cuts or drills holes in a single semi-finished product. S5. Finished Product Pickup: The finished product is transferred from the laser cutting module to the receiving system via the finished product pickup module.

[0018] The beneficial effects of this invention are: 1. By setting up an AOI coding module, real-time defect detection and coding marking are completed before the roll material is cut, so that each semi-finished product has a traceable identity before entering the laser cutting process. This enables quality control from the source, effectively prevents defective materials from entering subsequent processes, and improves the overall yield and production traceability.

[0019] 2. By designing a segmented cutting process using laser slicing modules, semi-finished product transfer modules, and laser cutting modules, roll cutting and single-piece cutting are separated, decoupling the processing cycle and improving overall production efficiency.

[0020] 3. By cooperating with two sets of laser processing units, a semi-finished product transfer module, and a finished product pickup module, alternating continuous operation is achieved, thereby shortening the single processing cycle and improving equipment utilization.

[0021] 4. By dividing the production line into a good product receiving area, a waste material area, and a defective product temporary storage area, the automatic classification and diversion of finished products, waste materials, and defective products are realized, reducing manual sorting steps and thus improving the automation level and operating efficiency of the production line.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0025] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0028] In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0029] In one embodiment of the present invention, such as Figure 1-11 As shown, a TPF laser cutting production line specifically implemented includes, in sequence along the conveying direction: a roll material feeding module 1, an AOI coding module 2, a laser slicing module 3, a semi-finished product transfer module 4, a laser cutting module 5, a finished product picking module 6, and a receiving system 7.

[0030] AOI coding module 2 is used to detect and mark the surface of the roll material before it enters the laser slicing module 3. Laser slicing module 3 is used to cut the coded roll material into single semi-finished products. Semi-finished product transfer module 4 is used to receive and carry the single semi-finished products output by laser slicing module 3 and transport the single semi-finished products to laser cutting module 5. Finished product picking module 6 is used to receive and carry the finished products output by laser cutting module 5 and transport the finished products to receiving system 7.

[0031] like Figure 3-5 As shown, the coil feeding module 1 includes a frame 11, several floating rollers 12, and guide rollers 13. The several floating rollers 12 are slidably mounted on the frame 11 via sliding seats. The frame 11 is provided with a counterweight assembly 14 and an adjustment assembly 15 that cooperate with the sliding seats. One end of the frame 11 is provided with a swingable rotating rod 16. Both ends of the rotating rod 16 are provided with swing arms 17. The ends of the swing arms 17 are provided with air-expanding chucks 18 for clamping the coil core. The air-expanding chucks 18 are connected to an external air supply system to achieve air inflation and tightening, thereby clamping the coil core and driving the coil to be released synchronously and stably during the conveying process.

[0032] In this embodiment, the air-expanding chuck 18 is rotatably mounted on the end of the swing arm 17 via a bearing seat. One of the swing arms 17 is equipped with a drive motor for driving the air-expanding chuck 18 to rotate. The output shaft of the drive motor is connected to the input shaft of the air-expanding chuck 18 via a belt transmission mechanism, thereby driving the roll material to be actively unwound. The frame 11 is equipped with a first drive member for driving the rotating rod 16 to swing, and the two ends of the rotating rod 16 are respectively equipped with second drive members for driving the swing arm 17 to reciprocate along the axial direction of the rotating rod 16.

[0033] Driven by the first driving component, the rotating rod 16 and the swing arm 17 can swing around the axis of the rotating rod 16, thereby adjusting the position of the air-expanding chuck 18, facilitating the loading and docking of the coil by the operator or robot. The second driving component controls the swing arm 17 to move axially along the rotating rod 16, so that the air-expanding chucks 18 at both ends can clamp towards the center or release to both sides, thereby achieving the clamping and release of the coil and ensuring the stability of the coil during unwinding.

[0034] During the unwinding process, the floating roller 12 can apply adjustable tension through the counterweight assembly 14 or the adjusting assembly 15 to keep the coil taut, thereby avoiding a decrease in subsequent processing accuracy due to slack or deviation. The counterweight assembly 14 consists of a pulley, a counterweight block, and a traction rope. One end of the traction rope is connected to the sliding seat, and the other end passes over the pulley and suspends the counterweight block. By adjusting the mass of the counterweight block, the tension applied by the floating roller 12 to the coil can be changed to adapt to the needs of coils of different materials and thicknesses.

[0035] The adjustment component 15 consists of a worm gear and a handwheel. The worm gear is rotatably mounted on the frame, and the worm wheel is threadedly connected to the sliding seat. Rotating the handwheel will drive the worm gear to rotate, which in turn drives the worm wheel to move, adjusting the initial position of the sliding seat and the floating roller, thereby achieving fine calibration of the initial tension of the coil.

[0036] Furthermore, the frame 11 is also equipped with an ion fan 19, which blows ion air toward the surface of the roll material to neutralize the static electricity generated by friction during the unwinding process, thereby effectively preventing static electricity from attracting dust or causing safety accidents, and ensuring that the surface of the roll material is clean and the operation is smooth.

[0037] like Figure 6 , Figure 7 as well as Figure 9 As shown, the AOI coding module 2 includes a bracket 21, a vertical detection component 22, a lateral detection component 23, and a coding component 24. A dust-adhesive roller 25 is located at one end of the bracket 21 near the roll material feeding module 1. A guide roller 26 for conveying the roll material is located inside the bracket 21. A pressure roller assembly 27 is located at one end of the bracket 21 near the laser slicing module 3. The dust-adhesive roller 25 is used to remove dust and impurities from the surface of the roll material, ensuring the accuracy of subsequent AOI inspection and coding processes. The pressure roller assembly 27 is used to flatten the roll material and stably convey it to the laser slicing module 3, preventing warping or displacement of the roll material when it enters the slicing station, thereby ensuring slicing accuracy and consistency.

[0038] The vertical detection component 22 includes a transmitter and a receiver. The transmitter consists of a first high-brightness linear light source that provides transmitted illumination to the material, and the receiver includes a vertical line array camera and a coaxial linear light source positioned in front of its lens to acquire surface reflection images of the material. The lateral detection component 23 consists of a second high-brightness linear light source and a matching lateral line array camera. The second high-brightness linear light source illuminates the material surface at an oblique angle.

[0039] The pressure roller assembly 27 includes an upper pressure roller and a lower pressure roller, forming a gap between them for the coil material to pass through. The upper pressure roller is driven to rise and fall by a third drive component, thereby adjusting the gap size to accommodate coil materials of different thicknesses. The lower pressure roller is mounted on the bracket 21 by a drive motor, providing stable conveying power for the coil material. Both the upper and lower pressure rollers are covered with an elastic material layer on their outer sides. This elastic material layer effectively increases the friction between the roller and the coil material, preventing slippage and reducing hard damage to the surface of the coil material, thus protecting the integrity of the coil material surface.

[0040] The coding assembly 24 includes an XY-axis moving mechanism and a coding head. The XY-axis moving mechanism is mounted on the bracket 21, and the coding head is fixedly mounted on the output end of the XY-axis moving mechanism. The XY-axis moving mechanism can drive the coding head to move precisely in the horizontal direction along the X and Y axes, thereby flexibly adjusting the working position of the coding head according to the preset marking position requirements, adapting to roll materials of different sizes and specifications, and completing the coding marking operation at the designated position of the roll material, ensuring that the coding position is accurate and clear, and meeting the product traceability requirements of subsequent processing procedures.

[0041] By printing codes on the roll material, each roll has a unique physical identifier. This identifier can be linked to the processing procedures in the subsequent production process, allowing the subsequent processing equipment to automatically call the corresponding processing parameters based on the identifier. This eliminates the need for repeated manual adjustments to equipment parameters, improving production adaptability and processing efficiency. It also facilitates the traceability of product production information throughout the entire process, enabling quick location of the problem link in the event of quality issues, thus facilitating quality management.

[0042] During operation, the time-division multiplexing controller synchronously triggers each light source and camera, enabling the sequential acquisition of transmission images, surface reflection images, and oblique projection images of the roll material. By integrating multiple sets of image information, various defects on the surface of the roll material can be completely identified, including surface bumps, foreign matter impurities, internal bubbles, and edge damage. This results in higher detection accuracy and avoids missed detections.

[0043] The coding component 24 can print a unique mark on the corresponding position of the roll material according to the location and level of the defect identified by detection, directly marking the defect information on the material. This not only facilitates the rapid identification of defect areas for corresponding processing in subsequent processes, but also provides an intuitive physical basis for quality statistics. Combined with the digital defect information completed by AOI detection, it realizes the dual correspondence between digital traceability and physical identification, further improving the control accuracy of the production process.

[0044] For example, when an unrepairable defect is detected, the spray gun can directly print a non-conforming mark on the defect area. When a repairable defect is detected, the spray gun will print a mark corresponding to the defect type. Subsequent processes can then perform rework based on the different marks, greatly improving the efficiency of defect handling and preventing unqualified semi-finished products from flowing into the next processing stage and wasting processing resources.

[0045] In this embodiment, the receiving system 7 includes a good product receiving area 71, a waste area 72, and a defective product temporary storage area 73. The good product receiving area 71 is used to receive qualified finished products conveyed by the finished product picking module 6. The waste area 72 is used to collect scrap materials generated during the processing. The defective product temporary storage area 73 is used to temporarily store defective products that do not meet the preset standards for subsequent re-inspection or processing.

[0046] Positioning trays are provided in the good product receiving area 71, waste material area 72, and defective product temporary storage area 73. The positioning trays are used to support and store the corresponding materials, which facilitates subsequent transfer and inventory by manual or automated equipment. Limiting blocks are set around the outer edge of the positioning trays to prevent materials from slipping off the trays during storage, ensuring a stable and orderly storage process and avoiding damage from falling materials.

[0047] Both the semi-finished product transfer module 4 and the finished product picking module 6 are robotic arms 61. The output end of the robotic arm 61 is equipped with a vacuum suction cup assembly 62, which features a vision inspection component 63. The six-axis robotic arm 61 can move flexibly within the workspace, enabling the vacuum suction cup assembly 62 to precisely grasp single semi-finished products output from the laser slicing module 3. The semi-finished products are then smoothly transferred to the processing station of the laser cutting module 5. After processing, the finished products are picked up and transported to the corresponding area of ​​the receiving system 7. The vacuum suction cup assembly 62 generates negative pressure through a vacuum generator, stably adsorbing single semi-finished and finished products, preventing slippage or drops during grasping, and ensuring a stable and reliable transfer process.

[0048] The vision inspection component 63 is used to identify the position, posture, and shape of semi-finished and finished products, thereby guiding the robotic arm 61 to move precisely to the target position to complete the grasping and transfer of semi-finished and finished products. This avoids misalignment and damage to the workpiece, improves the accuracy and stability of the transfer, and can also identify defective workpieces in advance based on the inkjet markings, avoids confusing qualified and unqualified workpieces, reduces ineffective transfer and processing, and improves overall production efficiency.

[0049] After the laser slicing module 3 cuts the roll material, the vacuum suction cup group 62 on the robotic arm 61 of the semi-finished product transfer module 4 will move to directly above the semi-finished product position according to the position of the semi-finished product identified by the vision detection component 63, and judge whether the semi-finished product has defects according to the defect information corresponding to the inkjet marking. If it is an unqualified semi-finished product, the robotic arm 61 will not grab the semi-finished product, and it will be directly transported by the laser slicing module 3 to the preset waste collection device such as the waste bin.

[0050] If the defect is repairable or the semi-finished product is qualified, the vacuum suction cup assembly 62 will pick it up and transfer it to the laser cutting module 5 for cutting. After the laser cutting module 5 completes the processing, the robotic arm 61 on the finished product picking module 6 will also identify the position and coding information of the finished product through the vision detection component 63, and pick up the finished product through the vacuum suction cup assembly 62 and transfer it to the corresponding area of ​​the receiving system 7.

[0051] When the finished product is of good quality, it is transferred to the good product receiving area 71 of the receiving system 7 for centralized stacking and storage, facilitating subsequent packaging and shipping. When the finished product is a defective product with repairable defects, it is transferred to the defective product temporary storage area 73 for storage, awaiting subsequent re-inspection and repair. Unrepairable defective products and waste generated from cutting are directly transported to the waste area 72 for centralized collection and processing. By classifying and storing finished products of different qualities, it is convenient to carry out targeted processing of products in different states, avoiding defective products from being mixed with good products and affecting the quality of shipment. It also enables centralized processing of waste, keeping the production site clean and orderly, thereby improving the standardization of the production process.

[0052] like Figure 6-8 As shown, the laser slicing module 3 includes a sheet conveyor belt 31 and a laser slicing assembly 32 disposed on the sheet conveyor belt 31. The laser slicing assembly 32 is located at one end of the sheet conveyor belt 31 near the AOI inkjet printing module 2. The sheet conveyor belt 31 is used to receive the inkjet-printed roll material output from the AOI inkjet printing module 2, and the laser slicing assembly 32 cuts the roll material into single semi-finished products. The cut semi-finished products continue to be conveyed forward along the conveyor belt in the conveying direction, so that the semi-finished product transfer module 4 can receive and convey them to the next process.

[0053] The laser slicing assembly 32 includes a linear module 321 and a laser cutting head 322 installed at the output end of the linear module 321. The linear module 321 can drive the laser cutting head 322 to reciprocate along a direction perpendicular to the roll material conveying. During the movement, the cutting head emits a high-energy laser to complete the transverse cutting of the roll material, thereby obtaining a single semi-finished product with regular dimensions.

[0054] The moving speed of the linear module 321 and the laser power of the cutting head can be preset and adjusted according to the material and thickness of the roll material, so as to adapt to the processing requirements of different specifications, ensure that the cutting edge is smooth and neat, avoid burrs or burnt edges, and ensure that the dimensional accuracy of the single semi-finished product meets the requirements of subsequent processing.

[0055] In this embodiment, the linear module 321 has a dual-drive structure, with two drive units respectively located at both ends of the linear module 321. The two drive units can reciprocate along the length of the linear module 321 and are each equipped with a laser cutting head 322.

[0056] By using two drive units to drive two laser cutting heads 322 to perform alternating cutting operations, production efficiency can be improved while avoiding the accumulation of high temperatures caused by prolonged operation of the laser cutting head 322. This allows sufficient time for the laser cutting head 322 to dissipate heat and cool down, thereby delaying the aging and wear of the optical path components of the cutting head, extending the service life of the equipment, and reducing equipment maintenance costs.

[0057] The laser cutting module 5 includes two sets of laser processing units 51, which can be arranged in a front-to-back or side-by-side along the conveying direction. In this embodiment, the two sets of laser processing units 51 are arranged side-by-side along the conveying direction. Each set of laser processing units 51 includes a worktable 511 and a cutting component 513 that can move horizontally on the worktable 511 via a moving module 512. The worktable 511 is provided with a fixing component 514 for fixing a single piece of semi-finished product.

[0058] In this embodiment, the moving module 512 is an XY axis gantry moving structure. The X-axis drive unit is arranged along the side of the worktable 511, and the Y-axis drive unit is mounted between the two X-axis drive units. The Y-axis drive unit is provided with two sliding frames, and both sliding frames can slide back and forth along the length direction of the Y-axis drive unit. Each sliding frame is equipped with a cutting component 513, and the two cutting components 513 can move independently along the Y-axis direction. In conjunction with the movement of the X-axis drive unit, the two cutting components 513 can perform independent movement operations within the processing area.

[0059] The two cutting components 513 can operate alternately or simultaneously. When the processing demand is large, the two cutting components 513 can simultaneously cut different processing areas of the same semi-finished product, thereby shortening the processing time of a single workpiece and improving overall processing efficiency. When the processing demand is small, the two cutting components 513 can work alternately, with one component remaining idle to dissipate heat while the other performs cutting operations. This maintains a stable production rhythm and avoids overheating and aging of the cutting components 513 due to prolonged continuous operation, extending the lifespan of optical components and reducing equipment failure rate and maintenance costs.

[0060] The fixing component 514 consists of several supporting adsorption plates. Vacuum adsorption holes are evenly distributed on the surface of the supporting adsorption plates. All vacuum adsorption holes are connected to an external vacuum generator through internal air channels. The single semi-finished product is firmly adsorbed and fixed on the worktable 511 by vacuum negative pressure, so as to avoid displacement of the semi-finished product during processing and ensure that the accuracy of laser cutting is not affected.

[0061] The support adsorption plate is made of a hollow and breathable non-metallic material, which can ensure that the vacuum adsorption force is evenly transmitted to the workpiece surface, reduce the reflection damage of the laser to the worktable 511 during laser cutting, extend the service life of the equipment, and reduce the impact of smoke generated during cutting on the cutting optical path, thereby improving the cutting quality.

[0062] The cutting component 513, driven by the moving module 512, moves along a preset cutting path to precisely cut the contours of the fixed semi-finished products, producing finished products that meet dimensional requirements. Through the alternating linkage between the semi-finished product transfer module 4 and the finished product pickup module 6 and the two laser processing units 51, continuous feeding of semi-finished products and continuous unloading of finished products can be achieved, thus realizing continuous processing. This avoids the wasted time of waiting for loading and unloading in a single processing unit, fully utilizing the equipment's processing capacity, further improving the overall production efficiency of the line, achieving highly automated continuous batch production, and meeting the processing needs of large-scale mass production.

[0063] like Figure 12 The production process shown is based on a TPF laser cutting production line and includes the following steps: S1. Feeding and Inspection / Coding: The roll material is fed out by the roll material feeding module 1 and the AOI coding module 2 completes real-time defect detection and coding. S2. Laser Slicing: Laser slicing module 3 cuts the roll material into single semi-finished products; S3. Semi-finished product transfer: The vision inspection component 63 on the robotic arm 61 aligns the vacuum suction cup group 62 with the single semi-finished product and picks it up, thereby transferring the single semi-finished product from the laser slicing module 3 to the worktable 511 of the idle laser processing unit 51. S4. Laser cutting: The laser processing unit 51 cuts or drills holes in a single semi-finished product. During this process, the two laser processing units 51 and the two robotic arms 61 work together to achieve alternating continuous operation. S5. Finished Product Pickup: The finished products are transferred from the laser cutting module 5 to the receiving system 7 via the finished product pickup module 6.

[0064] In step S5: the finished product picking module 6 transfers the processed finished products to the receiving system 7, and according to the judgment result of the vision inspection component 63, sends the finished products to the good product receiving area 71, sends the defective products and scrap to the waste area 72, and sends the reworkable products to the defective product temporary storage area 73, thereby realizing automated sorting. This not only facilitates the subsequent targeted processing of products in different states and avoids defective products from being mixed with good products and affecting the quality of shipment, but also enables centralized processing of waste materials, keeping the production site clean and orderly, thereby improving the standardization of the production process.

[0065] The beneficial effects of this invention are: 1. By setting up the AOI coding module 2, real-time defect detection and coding marking are completed before the roll material is cut, so that each semi-finished product has a traceable identity before entering the laser cutting process, realizing quality control from the source, effectively preventing defective materials from entering subsequent processes, and improving the overall yield and production traceability.

[0066] 2. By using a segmented cutting process design with laser slicing module 3, semi-finished product transfer module 4, and laser cutting module 5, roll cutting and single-piece cutting are separated, thus decoupling the processing cycle and improving overall production efficiency.

[0067] 3. By cooperating with two sets of laser processing units 51, semi-finished product transfer module 4, and finished product pickup module 6, alternating continuous operation is achieved, thereby shortening the single processing cycle and improving equipment utilization.

[0068] 4. By dividing the production line into a good product receiving area 71, a waste material area 72, and a defective product temporary storage area 73, the automatic classification and diversion of finished products, waste materials, and defective products are realized, reducing the manual sorting process and thus improving the automation level and operating efficiency of the production line.
