Description

Technical Field

[0001] This invention relates to the field of torsion testing devices, and in particular to a torsion testing device for aluminum profiles based on 3D line laser. Background Technology

[0002] In modern industrial production, aluminum profiles are widely used in construction, transportation, aerospace, and other industries due to their lightweight, high strength, and excellent processing performance. The torsion degree of aluminum profiles is a key indicator of their quality, directly affecting subsequent assembly accuracy and overall product performance. Therefore, accurately detecting the torsion degree of aluminum profiles is crucial for ensuring product quality.

[0003] Currently, 3D line laser-based inspection technology is widely used in the inspection of aluminum profile torsion due to its advantages such as non-contact operation, high precision, and high efficiency. The basic principle of this technology is to project a laser beam onto the surface of the aluminum profile using a 3D line laser emitter. After reflection from the surface, the laser beam is received by a laser receiver. By calculating parameters such as the reflection time and angle of the laser beam, and combining this with the principle of optical triangulation, the three-dimensional contour information of the aluminum profile surface can be accurately obtained, allowing for the analysis and calculation of the profile's torsion.

[0004] However, in the actual production process, dust, debris and other impurities inevitably adhere to the surface of aluminum profiles. These dust and debris will change the reflection path and intensity of the laser beam. When the laser beam irradiates the dust or debris, some of the laser will be diffusely reflected or scattered on the surface of the impurities, resulting in a weakening of the laser signal intensity reflected back to the laser receiver, which in turn leads to inaccurate twist test results. Summary of the Invention

[0005] The main objective of this invention is to provide a 3D line laser-based aluminum profile torsion detection device, which aims to improve the accuracy of aluminum profile torsion detection results.

[0006] To achieve the above objectives, this invention proposes a 3D line laser-based aluminum profile torsion detection device, comprising a transport frame, a detection mechanism for detecting profiles on the transport frame, and several conveying mechanisms for transporting profiles on the transport frame. Each conveying mechanism is rotatably connected to the transport frame and is spaced apart from the others. A cleaning mechanism is provided on the side of the transport frame near the detection mechanism. The cleaning mechanism includes a cleaning roller, several flexible bristles disposed on the outer surface of the cleaning roller, a first support plate disposed on both sides of the transport frame and fixedly connected to the transport frame, and a rotary motor. The cleaning roller is rotatably connected to the first support plate via a first rotating shaft and is disposed above the transport frame. The rotary motor is disposed on the side of the first support plate and fixedly connected to the first support plate, and the output end of the rotary motor is fixedly connected to the first rotating shaft.

[0007] In one possible implementation, each of the conveying mechanisms includes a first pulley and a second pulley respectively disposed on both sides of the transport frame and rotatably connected to the transport frame, and a first synchronous belt connecting the first pulley and the second pulley. The first pulley and the second pulley in each of the conveying mechanisms are spaced apart, and the first pulley and the second pulley in each of the conveying mechanisms are rotatably connected to the transport frame through a second rotating shaft. A drive motor is fixedly connected to the side of the transport frame, and the output end of the drive motor is connected to one of the second rotating shafts.

[0008] In one possible implementation, the cleaning roller includes a first cleaning sub-cylinder and a second cleaning sub-cylinder. The first rotating shaft is provided with a plurality of limiting blocks on one outer surface inside the first cleaning sub-cylinder and the second cleaning sub-cylinder. The first cleaning sub-cylinder and the second cleaning sub-cylinder are provided with limiting grooves that are slidably connected to each limiting block. The first support plate is also provided with a driving mechanism that causes the first cleaning sub-cylinder and the second cleaning sub-cylinder to reciprocate along the surface of the limiting blocks.

[0009] In one possible implementation, the driving mechanism includes a receiving cylinder respectively disposed on the sides of the first cleaning sub-cylinder and the second cleaning sub-cylinder, a movable cylinder rotatably connected to the receiving cylinder, an inclined plate disposed on the side of the movable cylinder away from the receiving cylinder, a limiting plate disposed on the top of the movable cylinder and fixedly connected to the movable cylinder, a rotating plate disposed on both sides of the first rotating shaft and fixedly connected to the first rotating shaft, and an elastic element disposed between the limiting plate and the first support plate. The first rotating shaft is rotatably connected to the inside of the movable cylinder. The rotating plate is provided with a plurality of push rods of different heights on the side near the inclined plate. Each push rod is circumferentially arranged with the center of the first rotating shaft as the center, and the height of each push rod gradually decreases. The push rod with the higher horizontal height on the rotating plate abuts against the side of the inclined plate near the first support plate. The top of the first support plate is provided with an extension block. A limiting rod is fixedly connected to one side of the extension block. The limiting plate is slidably connected to the limiting rod. The elastic element is sleeved on the surface of the limiting rod, and both sides of the elastic element are fixedly connected to the extension block and the limiting plate, respectively.

[0010] In one possible implementation, the receiving cylinder has a receiving groove inside, and a first rolling bearing is provided inside the receiving groove. The outer ring of the first rolling bearing is fixedly connected to the inner wall of the receiving groove. The moving cylinder is fixedly connected to the inner ring of the first rolling bearing. The moving cylinder has a through hole inside, and the inner diameter of the through hole is larger than the outer diameter of the first rotating shaft.

[0011] In one possible implementation, the transport frame is provided with a patting assembly for patting the flexible bristles on the side near the cleaning roller. The patting assembly includes a fixed plate disposed on both sides of the transport frame and fixedly connected to the transport frame, a patting cylinder rotatably connected to the fixed plate, a plurality of patting plates disposed on the outer surface of the patting cylinder and used for patting the flexible bristles, and a first servo motor disposed on the side of the fixed plate and fixedly connected to the fixed plate. The output end of the first servo motor is fixedly connected to the patting cylinder.

[0012] In one possible implementation, a dust collection assembly is also included, comprising a dust collection plate, a suction pipe, and a fan. A first connecting plate is fixedly connected to one side of the fixed plate. The dust collection plate is fixedly connected to the first connecting plate by bolts. A plurality of dust collection holes are provided on one side of the dust collection plate, and each dust collection hole faces the contact area between the beater plate and the flexible bristles. One end of the suction pipe is connected to the fan, and the other end of the suction pipe is connected to the dust collection plate.

[0013] In one possible implementation, the testing mechanism includes a testing box disposed on top of the transport frame, a slide rail disposed inside the testing box, a testing shell slidably connected to the slide rail, a laser emitter disposed inside the testing shell, a pusher for moving the testing shell, and a lifting assembly for lifting the profile into the testing box.

[0014] The lifting assembly includes a support frame disposed at the bottom of the transport frame, a lifting screw rotatably connected to the support frame, a second servo motor fixedly connected to the lifting screw, and lifting plates disposed in the gap between the first pulley and the second pulley respectively. Each of the lifting plates is fixedly connected by a second connecting plate.

[0015] In one possible implementation, a guide rod is fixedly connected to the top of the support frame, and the second connecting plate is slidably connected to the guide rod.

[0016] The technical solution of this invention, by setting up a cleaning mechanism, allows the operator to start a rotary motor before the profile inspection process. The output end of the rotary motor drives the first rotating shaft to rotate, which in turn drives the cleaning roller to rotate. At the same time, the flexible bristles on the cleaning roller rotate accordingly, contacting the profile surface and generating friction. Through mechanical force, dust, debris, and other impurities on the aluminum profile surface are removed, preventing dust from altering the reflection path and intensity of the laser beam. This ensures that the 3D line laser inspection device can accurately acquire the three-dimensional contour information of the aluminum profile surface, improving the accuracy of the torsion detection results.

[0029] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] refer to Figure 1-10 This embodiment proposes an aluminum profile torsion detection device based on 3D line laser, including a transport frame 1, a detection mechanism for detecting profiles on the transport frame 1, and a plurality of conveying mechanisms for transporting profiles on the transport frame 1. Each conveying mechanism is rotatably connected to the transport frame 1, and the conveying mechanisms are spaced apart from each other.

[0032] Furthermore, a cleaning mechanism is provided on the side of the transport frame 1 near the testing mechanism. The cleaning mechanism includes a cleaning roller 2, several flexible bristles 203 disposed on the outer surface of the cleaning roller 2, a first support plate 204 disposed on both sides of the transport frame 1 and fixedly connected to the transport frame 1, and a rotary motor 205. The cleaning roller 2 is rotatably connected to the first support plate 204 through a first rotating shaft 206, and the cleaning roller 2 is disposed above the transport frame 1. The rotary motor 205 is disposed on the side of the first support plate 204 and fixedly connected to the first support plate 204, and the output end of the rotary motor 205 is fixedly connected to the first rotating shaft 206.

[0033] In use, the operator can start the rotary motor 205. The output of the rotary motor 205 drives the first rotating shaft 206 to rotate, thereby driving the cleaning roller 2 to rotate. The flexible bristles 203 on the cleaning roller 2 rotate accordingly, contacting the surface of the profile and generating friction, thereby brushing away dust and impurities from the surface of the profile. This prevents dust from interfering with the reflection path and intensity of the laser beam, ensuring that the 3D line laser inspection device can accurately acquire the three-dimensional contour information of the aluminum profile surface, thereby improving the accuracy of the torsion detection results.

[0034] In addition, to improve the cleaning effect, an additional cleaning roller 2 can be set on the top of the transport frame 1. The cleaning roller 2 can be connected to the output end of the rotary motor 205 through the synchronous belt pulley assembly 8, so that no additional drive source is required, thereby reducing costs.

[0035] Furthermore, each conveying mechanism includes a first pulley 3 and a second pulley 301 respectively disposed on both sides of the transport frame 1 and rotatably connected to the transport frame 1, and a first synchronous belt 302 connecting the first pulley 3 and the second pulley 301. The first pulley 3 and the second pulley 301 in each conveying mechanism are spaced apart, and the first pulley 3 and the second pulley 301 in each conveying mechanism are rotatably connected to the transport frame 1 through a second rotating shaft 304. A drive motor 303 is fixedly connected to the side of the transport frame 1, and the output end of the drive motor 303 is connected to one of the second rotating shafts 304.

[0036] In operation, the operator arranges the profiles orderly on the surface of the first synchronous belt 302 and then starts the drive motor 303. The output of the drive motor 303 drives the second rotating shaft 304 to rotate, which in turn drives the second pulley 301 to rotate. The second pulley 301 drives the first pulley 3 to rotate via the first synchronous belt 302. While the second rotating shaft 304 rotates, the first synchronous belt 302 begins to move, thereby transporting the profiles on its surface. By setting up the first pulley 3, the second pulley 301, and the first synchronous belt 302, the operator can place multiple profiles on the surface of the first synchronous belt 302 simultaneously, eliminating the need for individual loading and inspection, thus improving the equipment's inspection efficiency.

[0037] Furthermore, due to the inherent weight of the profile, placing it on the surface of the first synchronous belt 302 may cause dents. To prevent this, support columns 7 are provided on both sides of the transport frame 1, and a second support plate 701 is installed on top of the support columns 7. The second support plate 701 is located at the bottom of the first pulley 3, and the bottom of the first pulley 3 is slidably connected to the top of the second support plate 701. This design provides rigid support for the transport of the profile, preventing the first synchronous belt 302 from denting due to excessive weight of the profile, thereby improving the stability of transport.

[0038] Furthermore, the testing mechanism includes a testing box 6 set on top of the transport frame 1, a slide rail 601 set inside the testing box 6, a testing shell 602 slidably connected to the slide rail 601, a laser emitter 603 set inside the testing shell 602, a pusher 604 that pushes the testing shell 602 to move, and a lifting assembly that lifts the profile into the testing box 6.

[0039] The lifting assembly includes a support frame 605 disposed at the bottom of the transport frame 1, a lifting screw 606 rotatably connected to the support frame 605, a second servo motor 607 fixedly connected to the lifting screw 606, and lifting plates 608 respectively disposed in the gap between the first pulley 3 and the second pulley 301. Each lifting plate 608 is fixedly connected by a second connecting plate 609. The lifting screw 606 is threadedly connected to one of the lifting plates 608. The second servo motor 607 is fixedly connected to the bottom of the support frame 605.

[0040] When the profile enters the inspection box 6 under the action of the first synchronous belt 302, the first synchronous belt 302 stops conveying. At this time, the operator starts the second servo motor 607, which drives the lifting screw 606 to rotate, thereby moving the lifting plate 608 towards the inspection box 6. The lifting plate 608 gradually lifts the profile through the gaps between the first synchronous belts 302. When the profile is lifted to be aligned with the position of the laser emitter 603 inside the inspection box 6, the operator starts the pusher 604. The telescopic rod of the pusher 604 pushes the inspection shell 602 to move along the slide rail 601, so that the laser emitter 603 can fully scan the surface of the aluminum profile. Compared with fixed position inspection, this can obtain more complete three-dimensional contour information.

[0041] After the inspection is completed, the telescopic rod of the pusher 604 retracts, causing the inspection housing 602 to return to its initial position. Subsequently, the second servo motor 607 rotates in the opposite direction, and the lifting screw 606 lowers the lifting plate 608. When the height of the lifting plate 608 is lower than the first synchronous belt 302, the second servo motor 607 is turned off, and the profile returns to the surface of the first synchronous belt 302. The above process is repeated when inspecting the next profile.

[0042] This solution, through its designed detection mechanism, can lift the aluminum profile into the detection box 6, providing a stable detection space for laser detection, avoiding interference from external dust, and further improving the accuracy of the detection.

[0043] Meanwhile, in order to improve the stability of the lifting plate 608 during the lifting process, a guide rod 610 is fixedly connected to the top of the support frame 605. The second connecting plate 609 is slidably connected to the guide rod 610. The guide rod 610 can provide guidance for the movement of the lifting plate 608, ensuring that the lifting plate 608 will not deviate or shake during the movement, so that the aluminum profile can be lifted smoothly and accurately to the designated position inside the detection box 6, ensuring the reliable operation of the detection device.

[0044] In this embodiment, the cleaning roller 2 includes a first cleaning sub-cylinder 201 and a second cleaning sub-cylinder 202. A first rotating shaft 206 is provided with a plurality of limiting blocks 2061 on one outer surface inside the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202. The first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202 are provided with limiting grooves 2062 that are slidably connected to each limiting block 2061. The first support plate 204 is also provided with a driving mechanism that causes the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202 to reciprocate along the surface of the limiting block 2061.

[0045] When the cleaning roller 2 rotates, the drive mechanism causes the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202 to move back and forth along the surface of the limiting block 2061, so that the flexible bristles 203 can clean the aluminum profile surface multiple times at different positions. Compared with the fixed cleaning method, this reciprocating cleaning method can remove dust from various parts of the aluminum profile surface more comprehensively and deeply, improve the cleaning effect, and thus better ensure the accuracy of 3D line laser detection and reduce detection errors caused by local dust residue.

[0046] Specifically, the drive mechanism includes a receiving cylinder 4 respectively disposed on the sides of the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202, a movable cylinder 401 rotatably connected to the receiving cylinder 4, an inclined plate 402 disposed on the side of the movable cylinder 401 away from the receiving cylinder 4, a limiting plate 403 disposed on the top of the movable cylinder 401 and fixedly connected to the movable cylinder 401, a rotating plate 404 disposed on both sides of the first rotating shaft 206 and fixedly connected to the first rotating shaft 206, and an elastic element 405 disposed between the limiting plate 403 and the first support plate 204. The first rotating shaft 206 is rotatably connected to the inside of the movable cylinder 401, and the rotating plate 404 is close to the inclined plate 402. A number of push rods 406 of different heights are provided on one side of 02. Each push rod 406 is circumferentially arranged with the center of the first rotating shaft 206 as the center, and the height of each push rod 406 gradually decreases. The push rod 406 with the higher horizontal height on the rotating plate 404 abuts against the side of the inclined plate 402 near the first support plate 204. An extension block 407 is provided on the top of the first support plate 204. A limit rod 408 is fixedly connected to one side of the extension block 407. The limit plate 403 is slidably connected to the limit rod 408. An elastic member 405 is sleeved on the surface of the limit rod 408, and the two sides of the elastic member 405 are fixedly connected to the extension block 407 and the limit plate 403, respectively.

[0047] Furthermore, the receiving cylinder 4 is provided with a receiving groove 409 inside, and a first rolling bearing 410 is provided inside the receiving groove 409. The outer ring of the first rolling bearing 410 is fixedly connected to the inner wall of the receiving groove 409. The moving cylinder 401 is fixedly connected to the inner ring of the first rolling bearing 410. The moving cylinder 401 is provided with a through hole 411 inside, and the inner diameter of the through hole 411 is larger than the outer diameter of the first rotating shaft 206.

[0048] When the first rotating shaft 206 rotates under the action of the rotary motor 205, the sliding connection between the limiting block 2061 and the limiting groove 2062 causes the first cleaning sub-cylinder 201 to rotate accordingly. At the same time, the rotating plate 404 also rotates with the first rotating shaft 206. When the push rod 406, which is at a higher horizontal height on the rotating plate 404, disengages from the side of the inclined plate 402, the elastic element 405 contracts and pulls the limiting plate 403 towards the first support plate 204. The limiting plate 403 drives the moving cylinder 401 to move along the limiting rod 408. Since the inner ring of the first rolling bearing 410 inside the accommodating cylinder 4 is fixedly connected to the moving cylinder 401, the moving cylinder 401 drives the accommodating cylinder 4 to move through the rolling bearing, thereby causing the first cleaning sub-cylinder 201 to move along the surface of the limiting block 2061. When the push rod 406, which is at a higher horizontal level on the rotating plate 404, re-contacts the inclined plate 402, the push rod 406 pushes the inclined plate 402 to move away from the first support plate 204. The elastic element 405 is stretched, and the inclined plate 402 drives the moving cylinder 401 to move, which in turn drives the receiving cylinder 4 to move away from the first support plate 204, realizing the reciprocating motion of the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202.

[0049] It should be noted that since the inner diameter of the through hole 411 is larger than the outer diameter of the first rotating shaft 206, the moving cylinder 401 is not affected by the first rotating shaft 206 during movement and will not rotate with it. Furthermore, since the receiving cylinder 4 and the moving cylinder 401 are connected by the first rolling bearing 410, when the receiving cylinder 4 rotates, only the outer ring of the rolling bearing will rotate, while the inner ring remains stationary, thus ensuring that the moving cylinder 401 does not rotate.

[0050] The first rolling bearing 410 significantly reduces the frictional resistance between components, reduces wear on components, ensures the smooth rotation and reciprocating movement of the cleaning roller 2, and extends the service life of each component of the cleaning mechanism.

[0051] This solution only requires the rotary motor 205 to rotate in one direction to achieve the reciprocating motion of the first cleaning sub-cylinder 201, avoiding wear caused by frequent forward and reverse rotation of the rotary motor 205, thereby effectively extending the service life of the rotary motor 205.

[0052] In this embodiment, a beating assembly for beating the flexible bristles 203 is also provided on the side of the transport frame 1 near the cleaning roller 2. The beating assembly includes a fixed plate 5 disposed on both sides of the transport frame 1 and fixedly connected to the transport frame 1, a beating cylinder 501 rotatably connected to the fixed plate 5, a plurality of beating plates 502 disposed on the outer surface of the beating cylinder 501 and used for beating the flexible bristles 203, and a first servo motor 503 disposed on the side of the fixed plate 5 and fixedly connected to the fixed plate 5. The output end of the first servo motor 503 is fixedly connected to the beating cylinder 501.

[0053] After the flexible bristles 203 on the cleaning roller 2 have cleaned the dust from the surface of the aluminum profile, dust may remain on the bristles, affecting the subsequent cleaning effect. At this time, the operator can start the first servo motor 503 while the cleaning roller 2 is rotating. The first servo motor 503 drives the tapping cylinder 501 to rotate, and the tapping plate 502 rotates accordingly, tapping the flexible bristles 203. The impact force removes the dust attached to the bristles, keeping the flexible bristles 203 clean. This allows for continuous and effective cleaning of the aluminum profile surface, further improving the cleaning efficiency and quality of the cleaning mechanism. It also ensures that the 3D line laser inspection device always operates under good cleaning conditions, maintaining the accuracy of the inspection results.

[0054] Furthermore, it also includes a dust collection assembly, which includes a dust collection plate 504, a suction pipe 505, and a fan 506. A first connecting plate 507 is fixedly connected to one side of the fixing plate 5. The dust collection plate 504 is fixedly connected to the first connecting plate 507 by bolts. A number of dust collection holes are provided on one side of the dust collection plate 504, and each dust collection hole faces the contact area between the beater plate 502 and the flexible bristles 203. One end of the suction pipe 505 is connected to the fan 506, and the other end of the suction pipe 505 is connected to the dust collection plate 504.

[0055] Even after the tapping component knocks the dust off the flexible brush bristles 203, if the dust falls onto the transport frame 1 or re-adheres to the aluminum profile surface, it will still affect the testing results.

[0056] The exhaust fan 506 generates suction and draws dust from the vicinity of the dust collection plate 504 through the suction pipe 505, thereby collecting the dust that has been knocked down, preventing secondary contamination of the aluminum profile surface and the testing device, maintaining a clean testing environment, further improving testing accuracy and the reliability of the testing device, and reducing the impact of dust on the health of operators.

[0057] Working principle:

[0058] In operation, the operator arranges the profiles orderly on the surface of the first synchronous belt 302 and then starts the drive motor 303. The output of the drive motor 303 drives the second rotating shaft 304 to rotate, which in turn drives the second pulley 301 to rotate. The second pulley 301 drives the first pulley 3 to rotate via the first synchronous belt 302. While the second rotating shaft 304 rotates, the first synchronous belt 302 begins to move, thereby transporting the profiles on its surface. By setting up the first pulley 3, the second pulley 301, and the first synchronous belt 302, the operator can place multiple profiles on the surface of the first synchronous belt 302 simultaneously, eliminating the need for individual loading and inspection, thus improving the equipment's inspection efficiency.

[0059] Subsequently, the profile passes through the cleaning mechanism. At this time, the operator can start the rotary motor 205. The output end of the rotary motor 205 drives the first rotating shaft 206 to rotate, thereby driving the cleaning roller 2 to rotate. The flexible bristles 203 on the cleaning roller 2 rotate accordingly, contacting the surface of the profile and generating friction, thereby brushing away dust and impurities from the surface of the profile. At the same time, when the first rotating shaft 206 rotates under the action of the rotary motor 205, the sliding connection between the limiting block 2061 and the limiting groove 2062 causes the first cleaning sub-cylinder 201 to rotate accordingly. Simultaneously, the rotating plate 404 also rotates with the first rotating shaft 206. When the push rod 406, which is at a higher horizontal height on the rotating plate 404, disengages from the side of the inclined plate 402, the elastic element 405 contracts and pulls the limiting plate 403 to move towards the first support plate 204. The limiting plate 403 drives the moving cylinder 401 to move along the limiting rod 408. Since the inner ring of the first rolling bearing 410 inside the accommodating cylinder 4 is fixedly connected to the moving cylinder 401, the moving cylinder 401 drives the accommodating cylinder 4 to move through the rolling bearing, thereby causing the first cleaning sub-cylinder 201 to move along the surface of the limiting block 2061. When the push rod 406, which is at a higher horizontal height on the rotating plate 404, re-contacts the inclined plate 402, the push rod 406 pushes the inclined plate 402 to move away from the first support plate 204, the elastic element 405 is stretched, the inclined plate 402 drives the moving cylinder 401 to move, and then drives the accommodating cylinder 4 to move away from the first support plate 204, realizing the reciprocating motion of the first cleaning sub-cylinder 201 and the second cleaning sub-cylinder 202.

[0060] When the profile enters the inspection box 6 under the action of the first synchronous belt 302, the first synchronous belt 302 stops conveying. At this time, the operator starts the second servo motor 607, which drives the lifting screw 606 to rotate, thereby moving the lifting plate 608 towards the inspection box 6. The lifting plate 608 gradually lifts the profile through the gaps between the first synchronous belts 302. When the profile is lifted to be aligned with the position of the laser emitter 603 inside the inspection box 6, the operator starts the pusher 604. The telescopic rod of the pusher 604 pushes the inspection shell 602 to move along the slide rail 601, so that the laser emitter 603 can fully scan the surface of the aluminum profile. Compared with fixed position inspection, this can obtain more complete three-dimensional contour information.

[0061] After the inspection is completed, the telescopic rod of the pusher 604 retracts, causing the inspection housing 602 to return to its initial position. Subsequently, the second servo motor 607 rotates in the opposite direction, and the lifting screw 606 lowers the lifting plate 608. When the height of the lifting plate 608 is lower than the first synchronous belt 302, the second servo motor 607 is turned off, and the profile returns to the surface of the first synchronous belt 302. The above process is repeated when inspecting the next profile.
