Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting equipment for processing photovoltaic bracket profiles. Background Art

[0002] At a time when the photovoltaic industry is booming, photovoltaic brackets are key components that support photovoltaic modules. The efficiency and quality of their production and processing play a vital role in the stability and cost control of the entire photovoltaic system. The processing of photovoltaic bracket profiles involves a variety of processes, among which laser cutting is an extremely important link.

[0003] However, in the loading process of traditional photovoltaic bracket profile laser cutting equipment, in order not to affect the loading operation, the guide structure needs to be equipped with a separate power source to store the guide structure, which has a low energy utilization rate. At the same time, due to the lack of reasonable guide support, when cutting longer profiles, the middle part of the profile is prone to shaking, further reducing the cutting quality;

[0004] In terms of profile clamping, conventional clamping methods are difficult to meet the fixing requirements of photovoltaic bracket profiles of different shapes and sizes. For some profiles of special shapes, the traditional clamping structure cannot provide a stable clamping force. During the cutting process, the profile will rotate or shift, causing the cutting path to deviate from the preset trajectory, making it impossible to achieve high-precision cutting and unable to meet the strict requirements of photovoltaic brackets for profile accuracy.

[0005] The treatment of cutting waste is also a major problem. The waste generated during the cutting process is easy to remain inside the profile. If it is not cleaned up in time, it will not only increase the difficulty and cost of the subsequent cleaning process, but may also scratch the inner wall of the profile during the waste accumulation process, affecting the quality and service life of the profile. The existing unloading structure often simply removes the cut profile from the processing area, while ignoring the key link of waste cleaning, resulting in an imperfect entire processing process.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10 and Fig.11 As shown, a laser cutting device for processing photovoltaic bracket profiles described in the present invention comprises a processing table 1, a walking structure 7 arranged on the processing table 1, a laser cutting head 8 arranged on the walking structure 7, a rotating clamping structure 2 arranged on the processing table 1, a material discharge structure 3 arranged on the processing table 1, a positioning structure 4 arranged on the material discharge structure 3, a loading table 9 arranged on one side of the processing table 1, a loading structure 5 arranged on the loading table 9, and a plurality of guide structures 6 arranged on the loading table 9;

[0037] The feeding structure 5 includes a three-jaw chuck 501 and a second screw 502. The three-jaw chuck 501 is slidably connected to the feeding platform 9. The second screw 502 is rotatably connected to the feeding platform 9. The second screw 502 is threadedly connected to the three-jaw chuck 501.

[0038] The guide structure 6 includes a fixed shaft 601 and a rotating frame 602. The loading platform 9 is rotatably connected with multiple fixed shafts 601. The fixed shaft 601 is fixedly connected with a rotating frame 602. Two movable plates 603 are symmetrically slidably connected to the rotating frame 602. Each movable plate 603 is rotatably connected with multiple rollers 604. A third screw 605 is rotatably connected to the rotating frame 602. The thread directions of the two ends of the third screw 605 are opposite. The third screw 605 is threadedly connected to the two movable plates 603. , two second gears 607 are fixedly connected to the fixed shaft 601, two racks 608 with non-L-shaped cross-sections are fixedly connected to the three-jaw chuck 501, and driving bars 609 are fixedly connected to both sides of the three-jaw chuck 501. A plurality of slide bars 610 are slidably connected to the loading platform 9, and a clamping block 611 is fixedly connected to the slide bar 610. A clamping groove 612 is provided on the fixed shaft 601, and the clamping block 611 is engaged with the clamping groove 612. A spring 614 is fixedly connected between the slide bar 610 and the loading platform 9;

[0039] The loading platform 9 is fixedly connected with a fourth motor 503, the output end of the fourth motor 503 is fixedly connected with the second screw 502, the loading platform 9 is fixedly connected with a guide rod 504, the three-jaw chuck 501 is slidably connected with the guide rod 504, the three-jaw chuck 501 is rotatably connected with a plurality of rollers 505, and the rollers 505 are rollingly connected with the loading platform 9; the rotating frame 602 is fixedly connected with a fixed rod 606, the movable plate 603 is slidably connected with the fixed rod 606, the loading platform 9 is fixedly connected with a plurality of fixed columns 613, the sliding bar 610 is slidably connected with the fixed column 613; the end of the driving bar 609 is inclined, and the sliding bar 610 is slidably connected with the fixed column 613; Both sides of the strip 610 are inclined, and a plurality of baffles 615 are fixedly connected to the loading platform 9, and the rotating frame 602 is in conflict with the baffles 615; the photovoltaic bracket profile is placed on the plurality of guide structures 5, and then the profile is fixed by the clamping action of the three-jaw chuck 501, and the fourth motor 503 is turned on, and its output end drives the second screw 502 to rotate. Since the second screw 502 is threadedly connected to the three-jaw chuck 501, and the three-jaw chuck 501 is slidably connected to the guide rod 504, under the action of the threaded transmission, the three-jaw chuck 501 slides on the material platform along the guide rod 504, and the roller 505 rolls on the material platform to reduce friction and assist movement. When the three-jaw chuck 501 moves, the three-jaw chuck The driving bars 609 on both sides of 501 contact the slide bar 610. Because the ends of the driving bars 609 and both sides of the slide bar 610 are inclined, the slide bar 610 will slide along the fixed column 613 and compress the spring 614 under the push of the driving bars 609. The block 611 on the slide bar 610 disengages from the slot 612 on the fixed shaft 601. At this time, the rotating frame 602 loses its restriction, and the three-jaw chuck 501 continues to move. The rack 608 on it meshes with the second gear 607 on the fixed shaft 601, driving the fixed shaft 601 to rotate, driving the rotating frame 602 to rotate, and continuing to rotate and fold under the action of gravity. The roller 604 on the moving plate 603 no longer supports the profile to avoid blocking the loading. At the same time, when When the three-jaw chuck 501 is reset, the driving bar 609 on the other side of the three-jaw chuck 501 will first contact the sliding bar 610. After the rotation restriction is released, when the rack 608 at the bottom end of the three-jaw chuck 501 moves, it will drive the second gear 607 to reset, and then drive the rotating frame 602 to reset. After rotating to a vertical state, the baffle 615 will resist the rotating frame 602 to prevent the rotating frame 602 from excessive rotation due to inertia. When it is necessary to cut profiles of different diameters, the third screw 605 can be rotated. The rotation of the third screw 605 will drive the two movable plates 603 to move toward or away from each other, thereby guiding and supporting profiles of different sizes, thereby improving the guiding effect.

[0040] Specifically, Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the rotating clamping structure 2 includes a swivel seat 201 and a gear ring 202 fixedly connected to the swivel seat 201, the swivel seat 201 is rotatably connected to the processing table 1, and the first motor 203 is fixedly connected to the processing table 1, and the output end of the first motor 203 is fixedly connected to the first gear 204, and the first gear 204 is meshed with the gear ring 202; four first hydraulic rods 205 are fixedly connected to the swivel seat 201, and the four first hydraulic rods 205 are arranged in a circular array, and the telescopic end of the first hydraulic rod 205 is fixedly connected to a connecting frame 206, and a slide 207 is slidably connected to the connecting frame 206, and a first screw 208 is rotatably connected to the connecting frame 206, and the first screw 208 is threadedly connected to the slide 207, and a mounting frame 209 is fixedly connected to the slide 207, and the mounting frame 209 is rotatably connected with a clamping shaft 210; the fourth motor 503 is started to reverse, so that the three-jaw chuck 501 drives the profile to move toward the processing table 1. When the profile moves to the rotating clamping structure 2, the fourth motor 503 is stopped and the first hydraulic rod 205 is started to shorten, and the connecting frame 206 is lowered accordingly, so that the clamping shaft 210 is aligned with the profile and clamped. At the same time, the position of the slide 207 on the connecting frame 206 can be adjusted by rotating the first screw rod 208, and then the position of the mounting frame 209 and the clamping shaft 210 is adjusted. The first motor 203 is started, and the first gear 204 at its output end drives the ring gear 202 to rotate, so that the swivel seat 201 and the clamped profile rotate, which is convenient for the laser cutting head 8 to perform circular cutting on the profile, and the walking structure 7 and the laser cutting head 8 are started. The walking structure 7 drives the laser cutting head 8 to move on the profile according to the preset path to perform cutting operations.

[0041] Specifically, Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, the unloading structure 3 includes a second motor 301 and a rotating shaft 302, the rotating shaft 302 is rotatably connected to the processing table 1, the second motor 301 is fixedly connected to the processing table 1, the output end of the second motor 301 is fixedly connected to the rotating shaft 302, a rotating frame 303 is fixedly connected to the rotating shaft 302, a mounting shaft 304 is fixedly connected to the rotating frame 303, a unloading plate 305 is rotatably connected to the mounting shaft 304; a fixed plate 306 is fixedly connected to the rotating frame 303, a second hydraulic rod 307 is rotatably connected to the fixed plate 306, the telescopic end of the second hydraulic rod 307 is rotatably connected to the bottom end of the unloading plate 305, and a unloading box 308 is placed on the processing table 1.

[0042] The positioning structure 4 includes a fixed frame 401 and a third hydraulic rod 402. The bottom end of the blanking plate 305 is fixedly connected to the fixed frame 401. The third hydraulic rod 402 is fixedly connected to the fixed frame 401. The telescopic end of the third hydraulic rod 402 is fixedly connected to a mounting box 403. The mounting box 403 is fixedly connected to a third motor 404. The output end of the third motor 404 is fixedly connected to a turntable 405. The turntable 405 is rotatably connected to the mounting box 403. The turntable 405 is provided with three arc-shaped drive grooves 404 in a circular array. 6. A driving shaft 407 is slidably connected to the driving groove 406, and a counter shaft 408 is rotatably connected to the driving shaft 407, and the counter shaft 408 contacts the inside of the profile; three guide shafts 409 are fixedly connected to the inside of the installation box 403, and the driving shaft 407 is slidably connected to the guide shaft 409; after the cutting is completed, the second motor 301 is started, and its output end drives the rotating shaft 302 to rotate, and the rotating frame 303 rotates accordingly, and the rotating frame 303 rotates to discharge the cut pipe into the pipe profile collection frame below. When the profiles of different lengths need to be cut, When cutting a profile, the third hydraulic rod 402 can be started to extend or shorten, thereby driving the installation box 403 to move, so that the shaft 408 enters the interior of the profile, and the third motor 404 is started, and its output end drives the turntable 405 to rotate, and the driving groove 406 on the turntable 405 drives the driving shaft 407 to slide along the guide shaft 409, so that the shaft 408 expands outward and hits the inner wall of the profile, and the profile is clamped and fixed internally, thereby improving the stability of the profile during cutting and improving the cutting effect. When the waste generated during cutting falls into the interior of the pipe, the second hydraulic rod 30 can be started. 7 contracts, the blanking plate 305 rotates and tilts around the installation shaft 304, and the waste inside the profile slides downward under the action of gravity and falls into the blanking box 308, while the profile will not fall because it is clamped inside, thus avoiding the trouble of cleaning up the waste later and improving the processing efficiency. When the pipe profile is blanked, the third hydraulic rod 402 can be extended, and the third hydraulic rod 402 drives the installation box 403 and the abutment shaft 408 to move together, thereby no longer clamping the inside of the profile. At this time, the second motor 301 is started, and when the rotating frame 303 is tilted, the profile will slide to the side collection structure under the action of gravity.

[0043] When the present invention is used, first, the photovoltaic support profile is placed on the multiple guide structures 5, and then the profile is fixed by the clamping action of the three-jaw chuck 501, and the fourth motor 503 is turned on, and its output end drives the second screw 502 to rotate. Since the second screw 502 is threadedly connected with the three-jaw chuck 501, and the three-jaw chuck 501 is slidably connected with the guide rod 504, under the action of the thread transmission, the three-jaw chuck 501 slides on the material table along the guide rod 504, and the roller 505 is on the material table. When the three-jaw chuck 501 moves, the driving bars 609 on both sides of the three-jaw chuck 501 contact the slide bar 610. Because the ends of the driving bars 609 and both sides of the slide bar 610 are inclined, the slide bar 610 will slide along the fixed column 613 and compress the spring 614 under the push of the driving bars 609. The block 611 on the slide bar 610 is separated from the slot 612 on the fixed shaft 601. At this time, the rotating frame 602 loses its restriction, and the three-jaw chuck 501 continues to move. The rack 608 on the three-jaw chuck 501 meshes with the second gear 607 on the fixed shaft 601, driving the fixed shaft 601 to rotate, driving the rotating frame 602 to rotate, and continuing to rotate and fold under the action of gravity. The roller 604 on the moving plate 603 no longer supports the profile to avoid blocking the loading of the material. At the same time, when the three-jaw chuck 501 is reset, the driving bar 609 on the other side of the three-jaw chuck 501 will first contact the sliding bar 610. After the rotation restriction is released one step ahead, when the rack 608 at the bottom of the three-jaw chuck 501 moves When the second gear 607 is moved, the second gear 607 is driven to reset, and then the rotating frame 602 is driven to reset. After rotating to the vertical state, the baffle 615 will resist the rotating frame 602 to prevent the rotating frame 602 from excessively rotating due to inertia. When it is necessary to cut profiles of different diameters, the third screw 605 can be rotated. The rotation of the third screw 605 drives the two moving plates 603 to move toward or away from each other, thereby guiding and supporting profiles of different sizes, thereby improving the guiding effect.

[0044] Then, the fourth motor 503 is started to reverse, so that the three-jaw chuck 501 drives the profile to move toward the processing table 1. When the profile moves to the rotating clamping structure 2, the fourth motor 503 is stopped and the first hydraulic rod 205 is started to shorten, and the connecting frame 206 is lowered accordingly, so that the clamping shaft 210 is aligned with the profile and clamped. At the same time, the position of the slide 207 on the connecting frame 206 can be adjusted by rotating the first screw rod 208, and then the position of the mounting frame 209 and the clamping shaft 210 is adjusted. The first motor 203 is started, and the first gear 204 at its output end drives the gear ring 202 to rotate, so that the swivel seat 201 and the clamped profile rotate, which is convenient for the laser cutting head 8 to perform circular cutting on the profile, and the walking structure 7 and the laser cutting head 8 are started. The walking structure 7 drives the laser cutting head 8 to move on the profile according to the preset path to perform cutting operations;

[0045] Finally, after the cutting is completed, the second motor 301 is started, and its output end drives the rotating shaft 302 to rotate, and the rotating frame 303 rotates accordingly. The rotating frame 303 rotates to discharge the cut pipe into the pipe profile collection frame below. When it is necessary to cut profiles of different lengths, the third hydraulic rod 402 can be started to extend or shorten, thereby driving the installation box 403 to move, so that the shaft 408 enters the interior of the profile, and the third motor 404 is started. The output end drives the turntable 405 to rotate, and the driving groove 406 on the turntable 405 drives the driving shaft 407 to slide along the guide shaft 409, so that the shaft 408 expands outward and contacts the inner wall of the profile, and the profile is clamped and fixed internally, thereby improving the profile during cutting. The stability is improved, and the cutting effect is improved. When the waste generated during cutting falls into the inside of the pipe, the second hydraulic rod 307 can be started to contract, and the unloading plate 305 can be rotated and tilted around the installation shaft 304. The waste inside the profile slides downward under the action of gravity and falls into the unloading box 308, and the profile will not fall because it is clamped inside, avoiding the trouble of subsequent waste cleaning and improving the processing efficiency. When unloading the pipeline profile, the third hydraulic rod 402 can be extended, and the third hydraulic rod 402 drives the installation box 403 to move together with the anti-shaft 408, and no longer clamps the inside of the profile. At this time, the second motor 301 is started. When the rotating frame 303 tilts, the profile will slide to the side collection structure under the action of gravity.
