Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting head for processing optoelectronic devices and a use method thereof. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. Laser cutting is a thermal cutting method. A high-power density laser beam irradiates the material to be cut, causing the material to be quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves across the material, the holes continuously form a very narrow slit, completing the cutting of the material.

[0003] During laser cutting, the laser beam generated by the laser cutting head will irradiate the material being cut, causing the material to be directly vaporized, thereby forming a very narrow slit. However, there are many semiconductor or metal materials in the optoelectronic devices being cut. When these materials are directly vaporized, they will produce harmful gases such as nitrogen oxides and heavy metal vapors, which will affect the health of the operators and the air environment. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a laser cutting head for processing optoelectronic devices, comprising a cutting head shell, an optical core is fixedly connected to the inner wall of the cutting head shell, and a ceramic ring is fixedly connected to the bottom of the cutting head shell; A flash removal mechanism, the flash removal mechanism comprises a raw material plate, a nozzle for removing flash from the raw material plate, a fixing block, an air pressure pipe, and an exhaust gas collecting mechanism for collecting exhaust gas from the raw material plate; The top of the nozzle is fixedly connected to the bottom of the ceramic ring, the outer wall of the fixed block is fixedly connected to the outer wall of the cutting head shell, and the outer wall of the air pressure tube is fixedly connected to the inner wall of the fixed block.

[0005] Preferably, the exhaust gas collection mechanism includes a fixed rod fixedly connected to the inner wall of the fixed block, a fan 1 is rotatably connected to the inner wall of the fixed rod, a guide wheel rod 1 is rotatably connected to the inner wall of the fan 1, and a bevel spring block is slidably connected to the inner wall of the guide wheel rod 1. When high-pressure auxiliary gas enters the cutting head housing through the air pressure pipe, the auxiliary gas will push the fan 1 to rotate rapidly. When the fan 1 rotates, the inner groove of the fan 1 will contact the straight surface of the bevel spring block, so that the fan 1 will synchronously drive the guide wheel rod 1 to rotate when it rotates.

[0006] Preferably, the exhaust gas collection mechanism also includes a belt mounted on the outer wall of the guide wheel rod 1, the inner wall of the fixed block is rotatably connected to the guide wheel rod 2, the outer wall of the guide wheel rod 2 is rotatably connected to the inner wall of the belt, the outer wall of the guide wheel rod 2 is fixedly connected to the fan 2, and the outer wall of the fixed block is fixedly connected to the wind collecting hood, when the guide wheel rod 1 rotates, the guide wheel rod 2 is driven to rotate synchronously through the belt, and when the guide wheel rod 2 rotates, the fan 2 is driven to rotate together.

[0007] Preferably, the exhaust gas collecting mechanism also includes an exhaust pipe fixedly connected to the outer wall of the air condensing hood, a connecting pipe fixedly connected to the inner wall of the fixed block, the outer wall of the connecting pipe is fixedly connected to the inner wall of the air condensing hood, a transparent air condensing hood is fixedly connected to the outer wall of the ceramic ring, the inner wall of the transparent air condensing hood is fixedly connected to the outer wall of the connecting pipe, a debris removal component is slidably connected to the inner wall of the exhaust pipe, and a protective component is fixedly connected to the bottom of the transparent air condensing hood. Taking advantage of the fact that high-pressure auxiliary gas is needed to remove flash during laser cutting, a fan 1 is provided. When the high-pressure auxiliary gas enters the cutting head shell through the air pressure pipe, the auxiliary gas will push the fan 1 to rotate rapidly. When rotating, the inner groove of fan one will contact with the straight surface of the inclined spring block, so that fan one will synchronously drive guide wheel rod one to rotate. When guide wheel rod one rotates, fan two will be driven to rotate through the belt and guide wheel rod two. When laser cutting the raw material plate, the high-temperature laser will directly vaporize the cutting part of the raw material plate, thereby generating high-temperature heavy metal vapor or other harmful gases, which will rise to the top of the transparent gas collection hood. When fan two rotates, these gases can be extracted through the connecting pipe and transported to the designated position through the exhaust pipe for unified treatment, thereby reducing the harmful gases generated during cutting from volatilizing into the air, affecting the health of workers and causing air pollution.

[0008] Preferably, the impurity removal component includes a conical plate slidably connected to the inner wall of the exhaust pipe, a telescopic spring is fixedly connected to the outer wall of the conical plate, a hydraulic pipe is fixedly connected to the outer wall of the exhaust pipe, a fixing ring is fixedly connected to the top of the transparent gas collecting hood, and the inner wall of the fixing ring is fixedly connected to the outer wall of the hydraulic pipe. When the gas passes through the exhaust pipe, the conical plate is pushed to move outward. When the conical plate moves outward, the hydraulic oil on its outside is squeezed so that it passes through the hydraulic pipe and enters the fixing ring.

[0009] Preferably, the impurity removal component also includes a rack slidably connected to the inner wall of the fixed ring 1, a filter plate 1 is fixedly connected to the inner wall of the connecting tube, a filter plate 2 is rotatably connected to the inner wall of the connecting tube, the bottom of the filter plate 2 is rotatably connected to the top of the filter plate 1, a convex tooth 1 is fixedly connected to the outer wall of the filter plate 2, the outer wall of the convex tooth 1 is meshed with the outer wall of the rack, a fixed column 1 is fixedly connected to the outer wall of the guide wheel rod 2, and a conical plate is provided by utilizing the characteristic that the fan 2 will make the gas pass through the exhaust pipe when it rotates. When the gas passes through the exhaust pipe, the conical plate will be pushed to move outward. When the conical plate moves outward, the hydraulic oil on its outer side will be squeezed to pass through the hydraulic pipe and enter the fixed ring 1, thereby pushing the rack to move. When the fan moves, the convex tooth 1 will drive the filter plate 2 to rotate, so that the filter holes of the filter plate 2 and the filter plate 1 that were originally completely interconnected are misaligned, forming smaller filter holes, so that some impurities can be filtered out when the gas is extracted, avoiding bringing some residues produced during cutting into the fixed rod connecting pipe and the exhaust pipe, thereby affecting its conveying efficiency. In addition, when the fan 2 stops rotating, the conical plate is reset by the action of the telescopic spring 1, and the hydraulic oil is driven to flow back, so that the filter holes on the filter plates 1 and 2 are completely overlapped again. At this time, some residues that were originally stuck in the misaligned filter holes will fall down due to the enlargement of the filter holes, thereby realizing self-cleaning of the filter holes and avoiding blockage of the filter holes, which affects the extraction of harmful gases.

[0010] Preferably, the impurity removal component also includes a vortex spring strip fixedly connected to the inner wall of the fixed column one, the outer wall of the vortex spring strip is fixedly connected with a convex tooth two, the inner wall of the fixed block is provided with a limiting groove, the inner wall of the exhaust pipe is fixedly connected with a one-way valve one, and the inner wall of the wind condenser is fixedly connected with a one-way valve two. By utilizing the above-mentioned characteristic that the guide wheel rod two can rotate, a vortex spring strip is provided, and when the guide wheel rod two rotates, it will synchronously drive the fixed column one to rotate. When the fixed column one rotates, the vortex spring strip will be wound up and accumulate elastic potential energy. When the elastic potential energy of the vortex spring strip accumulates to a maximum value, the convex tooth two will gradually disengage. When the fan 2 stops rotating, the convex tooth 2 will completely leave the current limiting groove, and rotate to the next limiting groove, and repeat this process until the fixed column 1 stops rotating. When the fixed column 1 stops rotating, the vortex spring strip releases the stored elastic potential energy, and drives the fan 2 to rotate through the fixed column 1 and the guide wheel rod 2. Since the rotation directions of the fan 2 are opposite at this time, when the fan 2 rotates, the external air will be sucked into the wind gathering hood through the one-way valve 2, and then passed through the connecting pipe to blow and clean the filter holes of the filter plates 1 and 2 to prevent impurities from sticking to the filter holes and affecting the extraction efficiency of harmful gases.

[0011] Preferably, the protective component includes a fixed column 2 fixedly connected to the bottom of the transparent gas gathering hood, a fixed ring 2 is fixedly connected to the bottom of the fixed column 2, a ball is rotatably connected to the inner wall of the fixed ring 2, and the outer wall of the ball is rotatably connected to the top of the raw material plate. When the nozzle moves, the fixed ring 2 is synchronously driven to move by the transparent gas gathering hood and the fixed column 2. When the fixed ring 2 moves, it drives the ball to roll on the surface of the raw material plate, so that it can provide certain fixed support for the raw material plate.

[0012] Preferably, the protection component also includes an anti-collision strip slidably connected to the inner wall of the second fixing ring, and the outer wall of the anti-collision strip is fixedly connected with a second telescopic spring, and one end of the outer wall of the second telescopic spring away from the anti-collision strip is fixedly connected to the inner wall of the second fixing ring. By utilizing the characteristic that the transparent gas gathering hood moves synchronously with the nozzle, a second fixing ring is provided. When laser cutting is performed, the nozzle moves and cuts at a specified distance on the raw material plate. When the nozzle moves, the second fixing ring is synchronously driven to move by the transparent gas gathering hood and the second fixing column, and when the second fixing ring moves, it drives the ball to roll on the surface of the raw material plate. The second fixing ring is provided with an anti-collision strip and a telescopic spring to prevent the raw material plate from being deformed, bulged or loosened during cutting, which may cause the nozzle to collide with the raw material plate and damage it, thereby preventing the normal operation of the equipment.

[0013] A method for using a laser cutting head for processing optoelectronic devices includes the following steps: S1: Install the equipment: Before using the equipment, first install the equipment at the required location, then connect the high-pressure auxiliary gas pipe with the air pressure pipe, and connect the external gas storage and purification chamber with the exhaust pipe; S2: Starting equipment: High-pressure auxiliary gas will push fan 1 to rotate rapidly through the air pressure pipe. When fan 1 rotates, it will synchronously drive guide wheel rod 1 to rotate. When guide wheel rod 1 rotates, it will drive fan 2 to rotate through the belt and guide wheel rod 2.

[0014] The present invention has the following beneficial effects: (1) The present invention utilizes the fact that high-pressure auxiliary gas is required to remove flash during laser cutting, and sets a fan 1. When the high-pressure auxiliary gas enters the cutting head shell through the air pressure tube, the auxiliary gas will push the fan 1 to rotate rapidly. When the fan 1 rotates, the inner groove of the fan 1 will contact the straight surface of the inclined spring block, so that the fan 1 will synchronously drive the guide wheel rod 1 to rotate. When the guide wheel rod 1 rotates, the fan 2 is driven to rotate through the belt and the guide wheel rod 2. When the raw material plate is laser cut, the high-temperature laser will directly vaporize the cutting part of the raw material plate, thereby generating high-temperature heavy metal vapor or other harmful gases, which will rise to the top of the transparent gas collection cover. When the fan 2 rotates, these gases can be extracted through the connecting pipe and transported to the designated location through the exhaust pipe for unified treatment, thereby reducing the harmful gases generated during cutting from volatilizing into the air, affecting the health of workers and causing air pollution.

[0015] (2) The present invention utilizes the characteristic that the fan 2 will make the gas pass through the exhaust pipe when it rotates, and sets a conical plate. When the gas passes through the exhaust pipe, it will push the conical plate to move outward. When the conical plate moves outward, it will squeeze the hydraulic oil on its outer side so that it passes through the hydraulic pipe and enters the fixed ring 1, thereby pushing the rack to move. When the rack moves, it will drive the filter plate 2 to rotate through the convex tooth 1, so that the filter holes of the filter plate 2 and the filter plate 1 that were originally completely interconnected are misaligned to form smaller filter holes, so that some of the filter holes can be removed when gas is extracted. Impurities are filtered out to avoid bringing some residues generated during cutting into the fixed rod connecting pipe and the exhaust pipe, which will affect the transportation efficiency. In addition, when the fan 2 stops rotating, the conical plate is reset by the action of the telescopic spring 1, and the hydraulic oil is driven to flow back, so that the filter holes on the filter plate 1 and the filter plate 2 are completely overlapped again. At this time, some residues that were originally stuck in the dislocated filter holes will fall down due to the enlargement of the filter holes, so as to achieve self-cleaning of the filter holes and avoid clogging of the filter holes, which affects the extraction of harmful gases.

[0016] (3) The present invention utilizes the above-mentioned characteristic that the guide wheel rod 2 can rotate, and sets a vortex spring strip. When the guide wheel rod 2 rotates, it will synchronously drive the fixed column 1 to rotate. When the fixed column 1 rotates, the vortex spring strip will be rolled up and elastic potential energy will be accumulated. When the elastic potential energy of the vortex spring strip accumulates to a maximum value, the convex tooth 2 will gradually disengage from the limit groove. At this time, the fixed column 1 continues to rotate, and the convex tooth 2 will completely disengage from the current limit groove and rotate to the next limit groove. This cycle repeats until the fixed column 1 stops rotating. When the fixed column 1 stops rotating, the vortex spring strip releases the accumulated elastic potential energy and drives the fan 2 to rotate through the fixed column 1 and the guide wheel rod 2. Since the directions of rotation of the fan 2 are opposite at this time, when the fan 2 rotates, the external air will be sucked into the wind collecting hood through the one-way valve 2, and then it will pass through the connecting pipe to blow and clean the filter holes of the filter plate 1 and the filter plate 2, so as to prevent impurities from adhering to the filter holes and affecting the extraction efficiency of harmful gases.

[0017] (4) The present invention utilizes the characteristic that the transparent gas gathering hood will move synchronously with the nozzle, and sets a fixed ring 2. When laser cutting is performed, the nozzle will move and cut at a specified distance on the raw material plate. When the nozzle moves, the fixed ring 2 is synchronously driven to move by the transparent gas gathering hood and the fixed column 2. When the fixed ring 2 moves, it drives the ball to roll on the surface of the raw material plate, so that it can provide a certain fixed support for the raw material plate, so that the raw material plate to be cut is relatively flat, and avoids the formation of a large temperature gradient and thermal stress due to the extremely high temperature at the laser spot and the low temperature of the surrounding raw material plates during laser cutting. When the thermal stress exceeds the yield strength of the raw material plate, the material is deformed, thereby affecting the cutting of the raw material plate. In addition, an anti-collision strip and a telescopic spring 2 are arranged outside the fixed ring 2 to prevent the raw material plate from deforming, bulging or the clamp from loosening during the cutting process, causing the nozzle to collide with the raw material plate and damage it, thereby affecting the normal operation of the equipment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For example, see Figure 1 - Figure 4The present invention is a laser cutting head for processing optoelectronic devices, comprising a cutting head housing 1, an optical core 101 is fixedly connected to the inner wall of the cutting head housing 1, and a ceramic ring 102 is fixedly connected to the bottom of the cutting head housing 1; The flash removal mechanism 2 includes a raw material plate 201, a nozzle 202 for removing flash from the raw material plate 201, a fixing block 203, an air pressure pipe 204, and an exhaust gas collecting mechanism 3 for collecting exhaust gas from the raw material plate 201; The top of the nozzle 202 is fixedly connected to the bottom of the ceramic ring 102 , the outer wall of the fixing block 203 is fixedly connected to the outer wall of the cutting head housing 1 , and the outer wall of the air pressure tube 204 is fixedly connected to the inner wall of the fixing block 203 .

[0023] The exhaust gas collecting mechanism 3 includes a fixed rod 301 fixedly connected to the inner wall of the fixed block 203, a fan 302 is rotatably connected to the inner wall of the fixed rod 301, a guide wheel rod 303 is rotatably connected to the inner wall of the fan 302, and an inclined spring block 304 is slidably connected to the inner wall of the guide wheel rod 303. When high-pressure auxiliary gas enters the cutting head housing 1 through the air pressure tube 204, the auxiliary gas will push the fan 302 to rotate rapidly. When the fan 302 rotates, the inner groove of the fan 302 will contact the straight surface of the inclined spring block 304, so that the fan 302 can synchronously drive the guide wheel rod 303 to rotate when rotating.

[0024] The exhaust gas collecting mechanism 3 also includes a belt 305 sleeved on the outer wall of the guide wheel rod 1 303, a guide wheel rod 2 306 is rotatably connected to the inner wall of the fixed block 203, the outer wall of the guide wheel rod 2 306 is rotatably connected to the inner wall of the belt 305, a fan 2 307 is fixedly connected to the outer wall of the guide wheel rod 2 306, and a wind collecting cover 308 is fixedly connected to the outer wall of the fixed block 203. When the guide wheel rod 1 303 rotates, the guide wheel rod 2 306 is driven to rotate synchronously through the belt 305, and when the guide wheel rod 2 306 rotates, the fan 2 307 is driven to rotate together.

[0025] The exhaust gas collecting mechanism 3 also includes an exhaust pipe 309 fixedly connected to the outer wall of the air condenser 308, a connecting pipe 310 is fixedly connected to the inner wall of the fixed block 203, the outer wall of the connecting pipe 310 is fixedly connected to the inner wall of the air condenser 308, a transparent air condenser 311 is fixedly connected to the outer wall of the ceramic ring 102, the inner wall of the transparent air condenser 311 is fixedly connected to the outer wall of the connecting pipe 310, a de-impurity component 4 is slidably connected to the inner wall of the exhaust pipe 309, and a protective component 5 is fixedly connected to the bottom of the transparent air condenser 311. In order to utilize the characteristic that high-pressure auxiliary gas is needed to remove flash during laser cutting, a fan 302 is set. When the high-pressure auxiliary gas enters the cutting head housing 1 through the air pressure pipe 204, the auxiliary gas will push the fan 302 to rotate rapidly. When 302 rotates, the inner groove of fan 1 302 will contact the straight surface of the inclined spring block 304, so that fan 1 302 can synchronously drive guide wheel rod 1 303 to rotate when rotating. When guide wheel rod 1 303 rotates, fan 2 307 is driven to rotate through belt 305 and guide wheel rod 2 306. When laser cutting of raw material plate 201 is performed, the high-temperature laser will directly vaporize the cutting part of raw material plate 201, thereby generating high-temperature heavy metal vapor or other harmful gases, which will rise to the top of transparent gas collection cover 311. When fan 2 307 rotates, these gases can be extracted through connecting pipe 310 and transported to the designated position through exhaust pipe 309 for unified treatment, so as to reduce the harmful gases generated during cutting from volatilizing into the air, affecting the health of workers and causing air pollution.

[0026] For example 2, please refer to Figure 5 - Fig.11 The present invention is a laser cutting head for processing optoelectronic devices. On the basis of the first embodiment, the impurity removal component 4 includes a conical plate 401 slidably connected to the inner wall of the exhaust pipe 309, a telescopic spring 402 is fixedly connected to the outer wall of the conical plate 401, a hydraulic pipe 403 is fixedly connected to the outer wall of the exhaust pipe 309, and a fixing ring 404 is fixedly connected to the top of the transparent gas collecting cover 311. The inner wall of the fixing ring 404 is fixedly connected to the outer wall of the hydraulic pipe 403. When the gas passes through the exhaust pipe 309, the conical plate 401 is pushed to move outward. When the conical plate 401 moves outward, the hydraulic oil on its outer side is squeezed to pass through the hydraulic pipe 403 and enter the fixing ring 404.

[0027] The impurity removal component 4 also includes a rack 405 slidably connected to the inner wall of the fixed ring 404, a filter plate 1 406 is fixedly connected to the inner wall of the connecting pipe 310, a filter plate 2 407 is rotatably connected to the inner wall of the connecting pipe 310, the bottom of the filter plate 2 407 is rotatably connected to the top of the filter plate 1 406, a convex tooth 1 408 is fixedly connected to the outer wall of the filter plate 2 407, the outer wall of the convex tooth 1 408 is meshedly connected to the outer wall of the rack 405, and a fixed column 1 409 is fixedly connected to the outer wall of the guide wheel rod 2 306. Utilizing the characteristic that the fan 2 307 will make the gas pass through the exhaust pipe 309 when rotating, a conical plate 401 is set, and when the gas passes through the exhaust pipe 309, the conical plate 401 will be pushed to move outward, and when the conical plate 401 moves outward, the hydraulic oil on the outside thereof will be squeezed to pass through the hydraulic pipe 403 and enter the fixed ring 1 404, and enter When the rack 405 is pushed to move, the convex tooth 1 408 drives the filter plate 2 407 to rotate when the rack 405 moves, so that the filter holes of the filter plate 2 407 and the filter plate 1 406, which were originally completely interconnected, are misaligned to form smaller filter holes, so that some impurities can be filtered out when gas is extracted, and it is avoided that some residues generated during cutting are brought into the fixed rod connecting pipe 310 and the exhaust pipe 309, thereby affecting their conveying efficiency. In addition, when the fan 2 307 stops rotating, the conical plate 401 is reset by the telescopic spring 1 402, and at the same time, the hydraulic oil is driven to flow back, so that the filter holes on the filter plate 1 406 and the filter plate 2 407 are completely overlapped again. At this time, some residues that were originally stuck in the misaligned filter holes will fall downward due to the enlargement of the filter holes, thereby realizing self-cleaning of the filter holes and avoiding clogging of the filter holes, which affects the extraction of harmful gases.

[0028] The impurity removal component 4 also includes a vortex spring strip 410 fixedly connected to the inner wall of the fixed column 1 409, a convex tooth 2 411 is fixedly connected to the outer wall of the vortex spring strip 410, a limiting groove 412 is provided on the inner wall of the fixed block 203, a one-way valve 1 413 is fixedly connected to the inner wall of the exhaust pipe 309, and a one-way valve 2 414 is fixedly connected to the inner wall of the wind condenser 308. By utilizing the above-mentioned feature that the guide wheel rod 2 306 can rotate, a vortex spring strip 410 is provided. When the guide wheel rod 2 306 rotates, the fixed column 1 409 is synchronously driven to rotate. When the fixed column 1 409 rotates, the vortex spring strip 410 is wound up and elastic potential energy is accumulated. When the elastic potential energy of the vortex spring strip 410 accumulates to the maximum value, the convex tooth 2 411 is gradually separated from the limiting groove. When the fixed column 409 stops rotating, the spiral spring strip 410 releases the stored elastic potential energy, and drives the fan 2 307 to rotate through the fixed column 1 409 and the guide wheel rod 2 306. Since the rotation direction of the fan 2 307 is opposite at this time, when the fan 2 307 rotates, the external air will be sucked into the wind collecting hood 308 through the one-way valve 2 414, and then passed through the connecting pipe 310 to blow and clean the filter holes of the filter plate 1 406 and the filter plate 2 407, so as to prevent impurities from sticking to the filter holes and affecting the extraction efficiency of harmful gases.

[0029] The protective component 5 includes a fixed column 501 fixedly connected to the bottom of the transparent gas gathering cover 311, and a fixed ring 502 is fixedly connected to the bottom of the fixed column 501. A ball 503 is rotatably connected to the inner wall of the fixed ring 502, and the outer wall of the ball 503 is rotatably connected to the top of the raw material plate 201. When the nozzle 202 moves, the fixed ring 502 is synchronously driven to move by the transparent gas gathering cover 311 and the fixed column 501. When the fixed ring 502 moves, it drives the ball 503 to roll on the surface of the raw material plate 201, so that it can provide a certain fixed support for the raw material plate 201.

[0030] The protection component 5 also includes an anti-collision strip 504 slidably connected to the inner wall of the second fixed ring 502, and a second telescopic spring 505 is fixedly connected to the outer wall of the anti-collision strip 504. One end of the outer wall of the second telescopic spring 505 away from the anti-collision strip 504 is fixedly connected to the inner wall of the second fixed ring 502. By utilizing the characteristic that the transparent gas gathering cover 311 will move synchronously with the nozzle 202, a second fixed ring 502 is set. When laser cutting is performed, the nozzle 202 will move and cut at a specified distance on the raw material plate 201. When the nozzle 202 moves, the second fixed ring 502 is synchronously driven to move by the transparent gas gathering cover 311 and the second fixed column 501. When the second fixed ring 502 moves, it drives the ball 503 to move in the raw material plate 201. The material plate 201 rolls on the surface thereof, so that it can provide a certain fixed support to the material plate 201, so that the material plate 201 to be cut is relatively flat, and the temperature at the laser spot is extremely high during laser cutting, while the temperature of the surrounding material plates 201 is relatively low, forming a large temperature gradient to generate thermal stress. When the thermal stress exceeds the yield strength of the material plate 201, the material is deformed, thereby affecting the cutting of the material plate 201. In addition, an anti-collision strip 504 and a telescopic spring 505 are arranged outside the fixing ring 202 to prevent the material plate 201 from deforming, bulging or the clamp from loosening during the cutting process, so as to prevent the nozzle 202 from colliding with the material plate 201 to cause damage, thereby preventing the normal operation of the equipment.

[0031] The method for using the laser cutting device for processing optoelectronic devices includes the following steps: S1: Install the equipment: Before using the equipment, first install the equipment at the required location, then connect the high-pressure auxiliary gas pipe to the air pressure pipe 204, and connect the external gas storage purification chamber to the exhaust pipe 309; S2: Starting equipment: High-pressure auxiliary gas passes through the air pressure pipe 204 to push the fan 1 302 to rotate rapidly. When the fan 1 302 rotates, the guide wheel rod 1 303 is synchronously driven to rotate. When the guide wheel rod 1 303 rotates, the fan 2 307 is driven to rotate through the belt 305 and the guide wheel rod 2 306.

[0032] A specific application of this embodiment is: before using the device, first install the device at the required position, then connect the high-pressure auxiliary gas pipe to the air pressure pipe 204, and connect the external gas storage purification chamber to the exhaust pipe 309. When the high-pressure auxiliary gas enters the cutting head housing 1 through the air pressure pipe 204, the auxiliary gas will push the fan 302 to rotate quickly. When the fan 302 rotates, the inner groove of the fan 302 will contact the straight surface of the inclined spring block 304, so that the fan 302 will synchronously drive the guide wheel rod 303 to rotate when rotating. When the guide wheel rod 303 rotates, The belt 305 and the guide wheel rod 306 drive the fan 307 to rotate. When the raw material plate 201 is laser cut, the high-temperature laser will directly vaporize the cut part of the raw material plate 201, thereby generating high-temperature heavy metal vapor or other harmful gases, which rise to the top of the transparent gas collecting cover 311. When the fan 307 rotates, these gases can be extracted through the connecting pipe 310 and transported to the designated location through the exhaust pipe 309 for unified treatment, thereby reducing the harmful gases generated during cutting from volatilizing into the air, affecting the health of workers and causing air pollution.

[0033] Taking advantage of the fact that the fan 2 307 causes the gas to pass through the exhaust pipe 309 when rotating, a conical plate 401 is provided. When the gas passes through the exhaust pipe 309, the conical plate 401 is pushed to move outward. When the conical plate 401 moves outward, the hydraulic oil on the outside thereof is squeezed to pass through the hydraulic pipe 403 and enter the fixing ring 1 404, thereby pushing the rack 405 to move. When the rack 405 moves, the filter plate 2 407 is driven to rotate through the convex tooth 1 408, so that the filter holes of the filter plate 2 407 and the filter plate 1 406, which were originally completely interconnected, are misaligned to form a smaller filter. The filter holes can filter out some impurities when gas is extracted, avoiding bringing some residues produced during cutting into the fixed rod connecting pipe 310 and the exhaust pipe 309, thereby affecting the conveying efficiency. In addition, when the fan 2 307 stops rotating, the conical plate 401 is reset by the telescopic spring 1 402, and the hydraulic oil is driven to flow back, so that the filter holes on the filter plate 1 406 and the filter plate 2 407 are completely overlapped again. At this time, some residues originally stuck in the misplaced filter holes will fall downward due to the enlargement of the filter holes, thereby realizing the self-cleaning of the filter holes. When the guide wheel rod 206 rotates, the fixed column 1 409 is synchronously driven to rotate. When the fixed column 1 409 rotates, the spiral spring strip 410 is rolled up and elastic potential energy is accumulated. When the elastic potential energy of the spiral spring strip 410 accumulates to the maximum value, the convex tooth 2 411 is gradually separated from the limiting groove 412. At this time, the fixed column 1 409 continues to rotate, and the convex tooth 2 411 is completely separated from the current limiting groove 412 and rotates to the next limiting groove 412, and this reciprocating process is repeated until the fixed column 1 409 is completely separated from the current limiting groove 412 and rotates to the next limiting groove 412. 9 stops rotating. When the fixed column 1 409 stops rotating, the spiral spring strip 410 releases the stored elastic potential energy, and drives the fan 2 307 to rotate through the fixed column 1 409 and the guide wheel rod 2 306. Since the rotation direction of the fan 2 307 is opposite at this time, when the fan 2 307 rotates, the external air will be sucked into the wind collecting cover 308 through the one-way valve 2 414, and then passed through the connecting pipe 310 to blow and clean the filter holes of the filter plate 1 406 and the filter plate 2 407 to prevent impurities from sticking to the filter holes and affecting the extraction efficiency of harmful gases.

[0034] Taking advantage of the fact that the transparent gas collecting cover 311 will move synchronously with the nozzle 202, a second fixing ring 502 is provided. When laser cutting is performed, the nozzle 202 will move and cut at a specified distance on the raw material plate 201. When the nozzle 202 moves, the second fixing ring 502 is synchronously driven to move by the transparent gas collecting cover 311 and the second fixing column 501. When the second fixing ring 502 moves, it drives the ball 503 to roll on the surface of the raw material plate 201, so that the raw material plate 201 can be fixed and supported to a certain extent, so that the raw material plate 201 to be cut is relatively flat. In order to avoid the situation that during laser cutting, the temperature at the laser spot is extremely high, while the temperature of the surrounding raw material plate 201 is relatively low, forming a large temperature gradient and generating thermal stress, when the thermal stress exceeds the yield strength of the raw material plate 201, the material is deformed, thereby affecting the cutting of the raw material plate 201. In addition, an anti-collision strip 504 and a telescopic spring 505 are arranged outside the fixing ring 502 to prevent the raw material plate 201 from deforming, bulging or the clamp from loosening during the cutting process, causing the nozzle 202 to collide with the raw material plate 201 and damage it, thereby affecting the normal operation of the equipment.
