Technical Field
[0001] This invention relates to the field of laser cutting technology, specifically to a short-pulse laser cutting device for semi-through cutting of composite materials. Background Technology
[0002] Partial cutting, also known as semi-cutting, is simply a processing technique that cuts only a portion of the material's thickness without completely severing it. It is often used to create creases, positioning grooves, or pre-reserved connection structures. Composite materials refer to new materials composed of two or more components with different chemical properties and physical forms, combined through a specific process. The short-pulse laser cutting equipment for composite material partial cutting uses picosecond or nanosecond pulsed lasers as its core. With the advantages of short pulse duration and small heat-affected zone, it can precisely control the cutting depth to achieve a partial cutting effect, avoiding problems such as delamination and carbonization of composite materials.
[0003] When performing partial cutting on composite materials, if the composite material is flexible, after being placed on the cutting table, there will be a gap between the bottom of the material and the table due to curling. This will cause a difference in the distance between the top of the material and the laser cutter, resulting in different cutting depths at different positions during the partial cutting process, which will affect the quality of the partial cutting. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a short-pulse laser cutting device for semi-through cutting of composite materials, comprising:
[0005] The frame has a dust cover installed on its top, and a cutting mechanism is installed at the center of the top of the frame, with the cutting mechanism located inside the dust cover.
[0006] The material conveying mechanism is installed on both sides of the frame;
[0007] The cutting mechanism includes a moving component and a cutting table. The cutting table includes a base plate, a top sliding plate slidably mounted on the top of the base plate, and a support plate fixedly mounted on the top of the top sliding plate. The support plate has inclined slots on both sides of its top, sloping downwards. Rubber gaskets are engaged with the inclined slots of the support plate. A hollow slot frame is slidably mounted in the inclined slots of the support plate, with the top of the hollow slot frame higher than the top of the support plate. The bottom of the hollow slot frame is tightly fitted with the top of the rubber gaskets. Through the cooperation of the support plate and the hollow slot frame, an air pump draws air from inside the inclined slots, creating a pressure difference with the outside air, thus increasing the cutting speed. Air pressure pushes the hollow slot frame to slide obliquely downwards within the inclined slot through the material. During this sliding process, the suction between the hollow slot frame and the bottom of the material pulls the material to both sides and flattens it while sliding at an angle. This ensures that the bottom of the material fits tightly against the top of the support plate, preventing differences in the distance between the top of the material and the laser cutter, which would result in different cutting depths at different locations during the semi-through cutting process and affect the quality of the semi-through cutting. A bottom cover is fixedly installed at the oblique slot at the bottom of the support plate, and an air pump is fixedly installed at the bottom of the top slide plate. A connecting pipe is fixedly installed at the air inlet of the air pump, and the air pump is connected to the bottom cover through the connecting pipe.
[0008] The top plate has protruding plates on both sides of its bottom, and the bottom plate has a first cylinder fixedly installed on both sides of its top. The output end of the first cylinder is fixedly connected to the protruding plate of the top plate.
[0009] Preferably, the moving component includes side slot plates, which are symmetrically installed on both sides of the base plate along the center of the base plate's axis. Each side slot plate has a sliding groove on its opposite surface. A first motor is fixedly installed at one end of each side slot plate. A first lead screw is rotatably installed on the inner wall of each side slot plate. The output end of the first motor is fixedly connected to one end of the first lead screw. A transverse slide plate is slidably installed between the side slot plates. The inner wall of the transverse slide plate is threadedly connected to the outer side of the first lead screw. A transverse slot plate is fixedly installed on the top of the transverse slide plate. A sliding groove is formed on the outer side of the transverse slot plate. A second lead screw is rotatably installed on the inner wall of the transverse slot plate. A second motor is fixedly installed at one end of the transverse slot plate. The output end of the second motor is fixedly connected to one end of the second lead screw. An inner slide plate is slidably installed at the sliding groove of the transverse slot plate. A laser cutter is fixedly installed on the inner wall of the inner slide plate.
[0010] Preferably, the material conveying mechanism includes a support platform, a stacking component is fixedly installed at the center of the top of the support platform, and a picking component is fixedly installed on the top of the support platform, the picking component being located above the stacking component.
[0011] Preferably, the stacking assembly includes a stacking frame, with upright plates on both sides of the top of the stacking frame, and a slot at the center of the top of the stacking frame. A material extraction plate is slidably installed in the slot of the stacking frame. Hole blocks are fixedly installed on both sides of the inner wall of the stacking frame, and a rotating shaft is rotatably installed between the hole blocks. A side inclined plate is rotatably installed on the outer side of the rotating shaft. The side inclined plate is inclined inward from top to bottom. When the material to be cut is placed in, the inclination of the side inclined plate guides the material downward as it moves. The material is guided by the contact between the two ends of the side inclined plate and the opposite surface of the side inclined plate, preventing the material from deviating. The bottom of the opposite surface of the side inclined plate is provided with a convex plate. The convex plate at the bottom of the opposite surface of the side inclined plate cooperates with the material extraction plate. When stacking the material to be cut, the top of the material extraction plate contacts the center of the bottom of the material, and the two ends of the material contact the convex plate. Gravity presses the side inclined plate, causing it to rotate and clamp the stacked material inward, preventing the material from deviating or tilting during the stacking process, which would cause the gripping position to shift.
[0012] Preferably, the material handling assembly includes a chute plate symmetrically installed on both sides of the top of the support platform. The top of the chute plate has a groove, and a sliding frame is slidably installed in the groove. Second cylinders are fixedly installed on the non-opposing sides of the chute plate, with their output ends fixedly connected to the outer side of the sliding frame. Third cylinders are fixedly installed on both sides of the sliding frame, with a crossbeam fixedly installed at the output end of each third cylinder. A connecting plate is fixedly installed on the outer side of the crossbeam. Vibrating suction cups are fixedly installed at the top corners of the connecting plate, with their bottom ends penetrating the connecting plate and extending to its bottom. Fixed frames are fixedly installed on both sides of the bottom of the connecting plate, with grooves on the outer side of each fixed frame, and a pressure plate slidably installed in the groove. When gripping material, the rubber strip at the bottom of the pressure plate first contacts the top of the material. The contact pressure between the rubber strip and the material is maintained by the suction of the vibrating suction cup and the weight of the pressure plate itself, increasing friction and preventing the material from shifting or tilting during the vibrating suction cup process. The rubber strip at the bottom of the pressure plate cooperates with the sliding groove of the fixed frame. During material gripping, the bottom of the pressure plate contacts the material first, followed by the vibrating suction cup. When releasing the material, the pressure plate continues to press the material for a certain distance after the vibrating suction cup releases it, preventing material movement during gripping and releasing. This prevents material from shifting, causing accumulation or misalignment during cutting. Furthermore, the bottom of the rubber strip is lower than the bottom of the vibrating suction cup.
[0013] This invention provides a short-pulse laser cutting device for semi-through cutting of composite materials. It has the following beneficial effects:
[0014] (i) The short-pulse laser cutting equipment applied to the semi-through cutting of composite materials uses a support plate and an empty slot frame to cooperate. An air pump draws air from inside the inclined slot to create an air pressure difference with the outside. The atmospheric pressure pushes the empty slot frame to slide obliquely downward in the inclined slot through the material. At the same time, during the sliding process, the adsorption between the empty slot frame and the bottom of the material is used to pull the material to both sides and flatten it while sliding at an angle. At the same time, the bottom of the material is tightly attached to the top of the support plate to avoid differences in the distance between the top of the material and the laser cutter, which would cause different cutting depths at different positions during the semi-through cutting process and affect the quality of the semi-through cutting.
[0015] (ii) The short-pulse laser cutting equipment applied to the semi-through cutting of composite materials uses a side inclined plate and a rotating shaft to guide the material when it is placed in for cutting. The inclined plate is tilted so that the material moves downward and the two ends contact the opposite surfaces of the side inclined plate to prevent the material from deviating.
[0016] (III) The short-pulse laser cutting equipment applied to the semi-through cutting of composite materials uses the convex plate at the bottom of the opposite side of the inclined plate to cooperate with the material extraction plate. When the material to be cut is stacked, the top of the material extraction plate contacts the center position of the bottom of the material, and at the same time, the two ends of the material contact the convex plate. The gravity presses the inclined plate, causing the inclined plate to rotate and clamp the stacked material inward, so as to prevent the material from shifting or tilting during the stacking process, which would cause the gripping position to shift.
[0017] (iv) The short-pulse laser cutting equipment applied to the semi-through cutting of composite materials uses a rubber strip at the bottom of the pressure plate to first contact the top of the material when gripping it. The contact pressure between the rubber strip and the material is ensured by the adsorption of the vibrating suction cup and the gravity of the pressure plate itself, which increases the friction and prevents the material from shifting or tilting during the vibrating suction cup process.
[0018] (v) The short-pulse laser cutting equipment applied to the semi-through cutting of composite materials uses the sliding groove of the fixed frame to cooperate with the pressure plate. During the material gripping process, the bottom of the pressure plate first contacts the material, and then the vibrating suction cup adsorbs the material. When the material is released, after the vibrating suction cup releases the material, the pressure plate continues to press the material for a certain distance, so as to avoid the material moving during the gripping and releasing process, which would cause the material to accumulate or the cutting position to be misaligned due to the movement.

[0033] 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.
[0034] For the first embodiment, please refer to... Figures 1 to 8 The present invention provides a technical solution:
[0035] A short-pulse laser cutting device for semi-through cutting of composite materials, comprising:
[0036] The frame 1 has a dust cover 2 installed on its top, and a cutting mechanism 4 is installed at the center of the top of the frame 1, with the cutting mechanism 4 located inside the dust cover 2.
[0037] Material conveying mechanism 3 is installed on both sides of frame 1;
[0038] The cutting mechanism 4 includes a moving component 41 and a cutting table 42. The cutting table 42 includes a base plate 421, a top slide plate 425 slidably mounted on the top of the base plate 421, and a support plate 423 fixedly mounted on the top of the top slide plate 425. A first cylinder 422 drives the top slide plate 425 to slide on the top of the base plate 421, causing the support plate 423 to move. When it approaches the feeding mechanism 3 containing the material to be cut, it cooperates with the feeding mechanism 3 to place the material onto the top of the support plate 423. Subsequently, the air pump 428 starts, and the material is fed through the connecting pipe 4... 29. Connecting the bottom cover 427, when material is placed in, the bottom of the material contacts the top of the empty slot frames 424 on both sides. The top of the support plate 423 has inclined slots on both sides, which slope downwards to both sides. Rubber gaskets 426 are engaged in the inclined slots of the support plate 423. Empty slot frames 424 are slidably installed in the inclined slots of the support plate 423, with the top of the empty slot frames 424 higher than the top of the support plate 423. The bottom of the empty slot frames 424 is tightly fitted with the top of the rubber gaskets 426. The bottom cover 427 is fixedly installed in the inclined slots at the bottom of the support plate 423. An air pump 428 is fixedly installed at the bottom of the top sliding plate 425. A connecting pipe 429 is fixedly installed at the air inlet end of the air pump 428. When the air pump 428 draws air from the inclined groove of the support plate 423, the bottom of the material is adsorbed through the groove of the empty groove frame 424, making the material stick tightly to the bottom of the empty groove frame 424. Then the air pump 428 continues to draw air, creating an air pressure difference with the outside. The atmospheric pressure outside pushes the empty groove frame 424 to slide in the inclined groove through the material, compressing the rubber pad ring 426. At the same time, when the empty groove frame 424 slides, the inclined groove is used to adsorb the material to both sides. The material is pulled to the side, causing it to flatten. Simultaneously, as the empty slot frame 424 moves diagonally downward, the bottom of the material adheres tightly to the top of the support plate 423. Then, the first cylinder 422 drives the support plate 423 through the top slide plate 425, bringing the material to the cutting position. After cutting, the first cylinder 422 moves the material closer to the conveying mechanism 3 on the other side. Then, the air pump 428 stops working, releasing the adhesion between the empty slot frame 424 and the material. Subsequently, the conveying mechanism 3 on the other side removes the cut material. The air pump 428 is connected to the bottom cover 427 through the connecting pipe 429.
[0039] The top slide plate 425 has protruding plates on both sides of its bottom, and the bottom plate 421 has a first cylinder 422 fixedly installed on both sides of its top. The output end of the first cylinder 422 is fixedly connected to the protruding plates of the top slide plate 425.
[0040] The moving assembly 41 includes side slot plates 411, which are symmetrically installed on both sides of the base plate 421 along the center of the axis of the base plate 421. Each side slot plate 411 has a sliding groove on its opposite surface. A first motor 412 is fixedly installed at one end of each side slot plate 411. A first lead screw 416 is rotatably installed on the inner wall of each side slot plate 411. The output end of the first motor 412 is fixedly connected to one end of the first lead screw 416. A transverse slide plate 419 is slidably installed between the side slot plates 411. The inner wall of the transverse slide plate 419 is threadedly connected to the outer side of the first lead screw 416. A transverse slot plate 413 is fixedly installed on the top of the transverse slide plate 419. A sliding groove is opened on the outer side of the transverse slot plate 413. A second lead screw 417 is rotatably installed on the inner wall of the transverse slot plate 413. After the material reaches the cutting position, the first motor... The first motor 412 works in conjunction with the second motor 415. The first motor 412 drives the first lead screw 416 to rotate inside the side slot plate 411. The first lead screw 416 is threadedly connected to the transverse slide plate 419, causing the transverse slide plate 419 to move laterally. At the same time, the second motor 415 drives the second lead screw 417 to rotate. The second lead screw 417 is threadedly connected to the inner slide plate 418, causing the inner slide plate 418 to drive the laser cutter 414 to move longitudinally. The laser cutter 414 performs a semi-through cut on the material. The second motor 415 is fixedly installed at one end of the transverse slot plate 413. The output end of the second motor 415 is fixedly connected to one end of the second lead screw 417. The inner slide plate 418 is slidably installed in the groove of the transverse slot plate 413. The laser cutter 414 is fixedly installed on the inner wall of the inner slide plate 418.
[0041] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 9 to 11 As shown, the material conveying mechanism 3 includes a support platform 31, a stacking assembly 32 is fixedly installed at the center of the top of the support platform 31, and a picking assembly 33 is fixedly installed on the top of the support platform 31, with the picking assembly 33 located above the stacking assembly 32.
[0042] The stacking assembly 32 includes a stacking frame 321. Vertical plates are provided on both sides of the top of the stacking frame 321, and a slot is formed at the center of the top of the stacking frame 321. A material extraction plate 322 is slidably installed in the slot of the stacking frame 321. Through the cooperation between the stacking frame 321 and the material extraction plate 322, the material extraction plate 322 provides support at the bottom of the material. Simultaneously, when stacking the material to be cut, both ends of the material contact the convex plates on the bottom of the opposite side of the inclined plate 323. Gravity causes the inclined plate 323 to rotate under the constraint of the rotating shaft 325, causing the top of the inclined plate 323 to move inward, clamping the stacked material. To prevent material misalignment, the inner walls of the stacking frame 321 are fixedly equipped with perforated blocks 324 on both sides. A rotating shaft 325 is rotatably installed between the perforated blocks 324. A side inclined plate 323 is rotatably installed on the outer side of the rotating shaft 325. The side inclined plate 323 is inclined inward from top to bottom. When the cut material is stacked, the side inclined plate 323 guides the material. At the same time, during the material stacking process, as the gravity gradually increases, the gravity drives the side inclined plate 323 to rotate through the convex plate, causing the side inclined plate 323 to rotate inward and clamp the material. The bottom of the opposite side of the side inclined plate 323 is provided with a convex plate.
[0043] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 12 to 13As shown, the material handling assembly 33 includes a chute plate 331, which is symmetrically installed on both sides of the top of the support platform 31. A chute is formed on the top of the chute plate 331, and a sliding frame 332 is slidably installed in the chute. Second cylinders 335 are fixedly installed on the non-opposing sides of the chute plate 331. The output end of the second cylinder 335 is fixedly connected to the outer side of the sliding frame 332. Third cylinders 337 are fixedly installed on both sides of the sliding frame 332. A crossbeam 336 is fixedly installed on the output end of the third cylinder 337. A connecting plate 333 is fixedly installed on the outer side of the crossbeam 336. Vibrating suction cups 334 are fixedly installed at the top corners of the connecting plate 333. The bottom end of the vibrating suction cup 334 penetrates the connecting plate 333 and extends to its bottom. Through the cooperation of the second cylinder 335 and the third cylinder 337, the second cylinder 335 drives the sliding frame 332 to slide on the chute plate 331. The sliding frame 332 moves closer to or further away from the cutting mechanism 4 by sliding within the groove. Simultaneously, the third cylinder 337 drives the crossbeam 336 to move up and down, causing the connecting plate 333 to move accordingly. During this movement, the plate moves downward, bringing the suction end of the vibrating suction cup 334 closer to the material for suction and gripping. Simultaneously, during the gripping process, the rubber strip at the bottom of the pressure plate 339 first contacts the top of the material. As it moves downward, the contact pressure causes the pressure plate 339 to slide upward within the groove of the fixed frame 338. Subsequently, the vibrating suction cup 334 contacts the material for suction and gripping. Fixed frames 338 are fixedly installed on both sides of the bottom of the connecting plate 333. A groove is provided on the outer side of the fixed frame 338, and the pressure plate 339 is slidably installed in the groove of the fixed frame 338. A rubber strip is provided at the bottom of the pressure plate 339, and the bottom of the rubber strip is lower than the bottom of the vibrating suction cup 334.
[0044] In use, the worker places the composite material to be partially cut into the feeding mechanism 3 on one side, and then starts the cutting mechanism 4. The material is fed into the cutting mechanism 4 through the feeding mechanism 3, and the material is partially cut by the cutting mechanism 4. After the cutting is completed, the material that has been partially cut is taken out from the cutting mechanism 4 through the feeding mechanism 3 on the other side.
[0045] In the cutting mechanism 4, the moving component 41 cooperates with the cutting table 42. The cutting table 42 provides support for material cutting, while the moving component 41 controls the laser cutting path to perform a semi-through cutting process on the material.
[0046] In the cutting table 42, the first cylinder 422 drives the top slide plate 425 to slide on the top of the base plate 421, causing the support plate 423 to move. When it approaches the feeding mechanism 3 containing the material to be cut, it cooperates with the feeding mechanism 3 to place the material on top of the support plate 423. Then, the air pump 428 starts and connects to the bottom cover 427 through the connecting pipe 429. When the material is placed, the bottom of the material contacts the top of the empty slot frames 424 on both sides. When the air pump 428 draws air from the inclined slots of the support plate 423, the bottom of the material is adsorbed through the slots of the empty slot frames 424, making the material stick tightly to the bottom of the empty slot frames 424. Then, the air pump 428 continues to draw air, forming a connection with the outside environment. The air pressure difference causes the atmospheric pressure on the outside to push the empty slot frame 424 to slide within the inclined channel, compressing the rubber pad ring 426. Simultaneously, as the empty slot frame 424 slides, the inclination of the inclined channel attracts and pulls the material to both sides, causing the material to flatten under the pull. At the same time, as the empty slot frame 424 moves downward at an angle, the bottom of the material is pressed tightly against the top of the support plate 423. Then, the first cylinder 422 drives the support plate 423 through the top slide plate 425, allowing the material to reach the cutting position. After the cutting is completed, the first cylinder 422 moves the material closer to the conveying mechanism 3 on the other side. Then, the air pump 428 stops working, releasing the attraction between the empty slot frame 424 and the material. Subsequently, the conveying mechanism 3 on the other side removes the material that has been cut.
[0047] In the moving assembly 41, after the material reaches the cutting position, the first motor 412 and the second motor 415 cooperate. The first motor 412 drives the first lead screw 416 to rotate inside the side slot plate 411. The first lead screw 416 is connected to the horizontal slide plate 419 by a thread, so that the horizontal slide plate 419 moves laterally. At the same time, the second motor 415 drives the second lead screw 417 to rotate. The second lead screw 417 is connected to the inner slide plate 418 by a thread, so that the inner slide plate 418 drives the laser cutter 414 to move longitudinally. The laser cutter 414 performs a semi-through cut on the material.
[0048] In the material conveying mechanism 3, the stacking component 32 and the picking component 33 cooperate to provide stacking space for materials, while the picking component 33 is responsible for picking up the materials.
[0049] In the stacking assembly 32, the stacking frame 321 cooperates with the extraction plate 322. The extraction plate 322 provides support at the bottom of the material. At the same time, when stacking the material to be cut, the two ends of the material contact the convex plate at the bottom of the opposite side of the inclined plate 323. Gravity drives the inclined plate 323 to rotate under the restriction of the rotating shaft 325, so that the top of the inclined plate 323 moves inward to clamp the stacked material and prevent the material from shifting. At the same time, when the material to be cut is stacked, the inclined plate 323 guides the material. During the material stacking process, as the gravity gradually increases, the gravity drives the inclined plate 323 to rotate through the convex plate, so that the inclined plate 323 rotates inward to clamp the material.
[0050] In the material handling assembly 33, the second cylinder 335 and the third cylinder 337 work together. The second cylinder 335 drives the sliding frame 332 to slide in the groove of the sliding plate 331, so that the sliding frame 332 moves closer to or away from the cutting mechanism 4. At the same time, the third cylinder 337 drives the crossbeam 336 to move up and down, so that the connecting plate 333 moves accordingly. During the movement, it moves downward, so that the suction end of the bottom of the vibrating suction cup 334 approaches the material and suctions and grasps the material. At the same time, during the material grasping process, the rubber strip at the bottom of the pressure plate 339 first contacts the top of the material. During the downward movement, the contact pressure causes the pressure plate 339 to slide upward in the groove of the fixed frame 338. Then the vibrating suction cup 334 contacts the material to suction and grasp it.
