Description

Technical Field

[0001] This invention relates to the field of aluminum-zinc-silicon plating inspection technology, specifically to a visual inspection device based on aluminum-zinc-silicon plating production and processing. Background Technology

[0002] Aluminized zinc-silicon coating combines the corrosion resistance of aluminum with the sacrificial anode protection properties of zinc. The addition of silicon further enhances the material's heat resistance and formability, making it widely used in industries such as construction, home appliances, and automobiles. However, during the production and processing of aluminized zinc-silicon coating, various defects can appear on the surface due to factors such as raw material quality, production process parameters, and equipment condition. These defects include scratches, roller marks, incomplete coating, uneven zinc bloom, and inclusions. These defects not only affect the product's appearance but also reduce its mechanical and corrosion resistance, thus impacting its lifespan and market competitiveness. Therefore, visual inspection equipment is needed to inspect aluminized zinc-silicon coating materials. Currently, there are some problems to be solved when using visual inspection instruments to inspect the surface of aluminum-zinc-silicon coated materials. Due to the special reflective properties of the aluminum-zinc-silicon coated surface, the reflectivity varies greatly at different angles. Existing inspection equipment cannot quickly and flexibly change the tilt angle of the aluminum-zinc-silicon coated material placed on the upper surface of the inspection platform. This results in the inability to adjust the angle in time according to the reflectivity of the aluminum-zinc-silicon coated surface during actual inspection, leading to low inspection preparation efficiency. Moreover, because the reflectivity problem cannot be effectively solved, the visual inspection instrument often fails to clearly capture the defects on the surface of the aluminum-zinc-silicon coated material, resulting in inaccurate and incomplete inspection results, which are difficult to meet the high-quality inspection requirements of production and processing.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a visual inspection device based on aluminum-zinc-silicon plating production and processing, which has the following beneficial effects: 1. The set detection angle adjustment mechanism can change the tilt angle of the aluminum-zinc-silicon plate material placed on the upper surface of the detection platform, so that the vision inspection instrument can inspect the surface of the aluminum-zinc-silicon plate material. It can not only quickly change the tilt angle of the detection platform, but also make the operation convenient. The angle can be adjusted in time according to the reflectivity of the aluminum-zinc-silicon plate surface, improving the efficiency of detection preparation. Moreover, the angle of the detection platform can be flexibly adjusted according to the reflectivity of the aluminum-zinc-silicon plate surface, avoiding the inability of the vision inspection instrument to clearly capture surface defects due to reflection problems, thus ensuring the accuracy and comprehensiveness of the detection.

[0016] 2. The rack and pinion mechanism and transmission gears drive the inspection table to continuously change its tilt direction, allowing the vision inspection instrument to inspect the surface of the aluminum-zinc-silicon plate material fixed on the upper surface of the inspection table from different angles. This not only enables the vision inspection instrument to inspect the surface of the aluminum-zinc-silicon plate from multiple different angles, effectively avoiding blind spots and improving the comprehensiveness of the inspection, but also allows for rapid and continuous changes in the angle of the inspection table without the need for repeated manual adjustment of the fixing device to change the inspection angle, reducing downtime during the inspection process and thus improving overall inspection efficiency. The side plates and auxiliary rods improve the stability of the inspection table during movement. This not only reduces inspection deviations caused by shaking and tremors, ensuring that the vision inspection instrument can accurately capture surface defect information of the aluminum-zinc-silicon plate and improve the accuracy of the inspection results, but also makes the inspection process smoother. It eliminates the need to frequently pause the inspection due to equipment instability for adjustments, thus helping to improve the overall inspection efficiency.

[0017] 3. Through the set detection angle reference mechanism, not only can the descent distance of the lifting block be visualized, but the staff can also accurately control the descent distance according to the scale, thereby precisely adjusting the tilt angle of the detection table to meet the high-precision detection requirements. Moreover, the precise tilt angle adjustment can ensure that the aluminum-zinc-silicon plate is at a suitable and consistent angle during each test, reducing detection errors caused by angle differences and ensuring the consistency and reliability of the test results.

[0018] 4. The disc and second spring enable the lifting block and the contact plate to automatically reset. The automatic reset function not only ensures that the contact plate returns to its initial position accurately every time, avoiding deviations that may occur during manual reset and ensuring the consistency and stability of the detection conditions, but also eliminates the need for manual reset of the contact plate, relying on the spring rebound force to complete the process automatically, saving operation time and manpower, and making the detection process more compact and efficient.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] A visual inspection device based on aluminum-zinc-silicon plating production and processing, such as Figure 1 - Figure 7 As shown, the system includes a worktable 1, a vision inspection instrument 3 fixedly connected to the upper surface of the worktable 1, a sliding groove 6 provided on the upper surface of the worktable 1, and an inspection table 2 positioned above the worktable 1, located between the vision inspection instrument 3 and the worktable 1. It also includes an inspection angle adjustment mechanism and an inspection angle reference mechanism. The inspection angle adjustment mechanism includes a support column 404, which is fixedly connected to the upper surface of the worktable 1. A connecting ball 403 is fixedly connected to the upper end of the support column 404, and a universal ball 402 is movably connected to the connecting ball 403. The universal ball 402 is fixedly connected to the center of the lower surface of the inspection table 2. The inspection angle adjustment mechanism is used to adjust the tilt angle of the inspection table 2.

[0022] In this embodiment, as Figure 4 and Figure 5 As shown, a transmission gear 405 is rotatably connected to the outer surface of the support column 404. A limit plate 408 is symmetrically fixedly connected to the upper end face of the transmission gear 405. The upper end faces of the two limit plates 408 are both inclined surfaces. A lifting rod 416 is attached to the upper end face of the two limit plates 408. The lifting rod 416 is in contact with the lower end face of the detection table 2. When the lifting rod 416 moves along the inclined surface of the limit plate 408, it will push the detection table 2 to move synchronously, causing the detection table 2 to tilt.

[0023] In this embodiment, as Figure 5 As shown, each of the two limiting plates 408 has a through groove 409, and each of the two through grooves 409 has a slider 410 slidably connected in it. The upper surfaces of the two sliders 410 are symmetrically fixedly connected to vertical plates 414. A ring 415 is fixedly connected between the two vertical plates 414 located on the same slider 410. A lifting rod 416 is slidably connected to the ring 415. A linkage plate 411 is symmetrically fixedly connected between the two sliders 410. When one slider 410 slides in the through groove 409, the linkage plate 411 can pull the other slider 410 to move synchronously.

[0024] In this embodiment, as Figure 5 As shown, a threaded rod 417 is threadedly connected to one of the sliders 410. The threaded rod 417 is rotatably connected to one of the limiting plates 408. A knob 418 is fixedly connected to one end of the threaded rod 417 that passes through the limiting plate 408. When the knob 418 is rotated, the threaded rod 417 is rotated. Through the threaded connection between the threaded rod 417 and the slider 410, the slider 410 can move horizontally within the through groove 409.

[0025] In this embodiment, as Figure 5As shown, the upper end face of the transmission gear 405 is symmetrically and fixedly connected to a side plate 412. The upper end face of each side plate 412 is fixedly connected to an auxiliary rod 413. Both auxiliary rods 413 are attached to the lower end face of the testing table 2. When the transmission gear 405 rotates, the side plate 412 can drive the auxiliary rods 413 to move synchronously attached to the lower end face of the testing table 2.

[0026] In this embodiment, as Figure 5 and Figure 6 As shown, a rack plate 406 is meshed with the transmission gear 405 near the slide groove 6. A slide plate 407 is fixedly connected to the lower end face of the rack plate 406. The slide plate 407 is slidably connected in the slide groove 6. When the rack plate 406 moves horizontally on the upper end face of the worktable 1 through the slide plate 407 and the slide groove 6, the rack plate 406 will drive the transmission gear 405 to rotate synchronously.

[0027] In this embodiment, as Figure 6 As shown, a connecting plate 401 is fixedly connected to the center of the rack plate 406 on the side away from the transmission gear 405. A locking pin 420 is slidably connected through the connecting plate 401. A locking hole 422 is symmetrically opened on the upper end face of the worktable 1. The locking pin 420 and the locking hole 422 are locked together. A handle 419 is fixedly connected to the upper end of the locking pin 420. A first spring 421 is fixedly connected between the handle 419 and the connecting plate 401. The first spring 421 is sleeved on the outer surface of the locking pin 420. By locking the locking pin 420 and the locking hole 422 together, the positions of the connecting plate 401 and the rack plate 406 can be limited and fixed.

[0028] Compared with existing technologies, this method can change the tilt angle of the aluminum-zinc-silicon plate material placed on the upper surface of the inspection stage 2, so that the vision inspection instrument 3 can inspect the surface of the aluminum-zinc-silicon plate material. This not only allows for quick changes in the tilt angle of the inspection stage 2, making operation convenient, but also enables timely adjustment of the angle according to the reflectivity of the aluminum-zinc-silicon plate surface, improving inspection preparation efficiency. Furthermore, it allows for flexible adjustment of the angle of the inspection stage 2 according to the reflectivity of the aluminum-zinc-silicon plate surface, avoiding the inability of the vision inspection instrument 3 to clearly capture surface defects due to reflection problems, thus ensuring the accuracy and comprehensiveness of the inspection.

[0029] In other aspects, this embodiment also provides a reference mechanism for the detection angle of the detection table 2, which facilitates precise control and adjustment by the operator. Figure 1 , Figure 2 and Figure 7 As shown, the detection angle reference mechanism includes a support plate 501, which is fixedly connected to the workbench 1. A connecting groove 502 is provided on the support plate 501, and a lifting block 503 is slidably connected in the connecting groove 502. An abutment plate 509 is fixedly connected to the side of the lifting block 503 near the detection table 2, and the abutment plate 509 is attached to the lower end face of the detection table 2.

[0030] In this embodiment, as Figure 7 As shown, a lifting column 506 is fixedly connected to the upper end of the lifting block 503. The lifting column 506 is slidably connected to the support plate 501. A disc 508 is fixedly connected to the upper end of the lifting column 506. A second spring 507 is fixedly connected between the disc 508 and the support plate 501. The second spring 507 is sleeved on the outer surface of the lifting column 506. When the lifting block 503 is subjected to force and descends, it will pull the lifting column 506 to drive the disc 508 to descend synchronously, squeezing the second spring 507. When the force on the lifting block 503 disappears, the rebound force of the second spring 507 can push the disc 508 to pull the lifting block 503 to rise automatically through the lifting column 506.

[0031] In this embodiment, as Figure 7 As shown, pointers 504 are fixedly connected to both sides of the lifting block 503. Scale bars 505 are symmetrically and equidistantly fixedly connected to the support plate 501 on the side near the pointers 504. The pointers 504 and scale bars 505 correspond to each other. When the lifting block 503 moves up and down, the distance of movement of the lifting block 503 can be accurately determined by observing the scale bar 505 pointed to by the pointers 504.

[0032] Compared with existing technologies, the ability to precisely control the tilt angle of the testing platform 2 not only visualizes the descent distance of the lifting block 503, allowing staff to accurately control the descent distance based on the scale, but also precisely adjusts the tilt angle of the testing platform 2 to meet high-precision testing requirements. Furthermore, the precise tilt angle adjustment ensures that the aluminum-zinc-silicon plate is at a suitable and consistent angle during each test, reducing testing errors caused by angle differences and ensuring the consistency and reliability of test results.

[0033] The overall working process and principles involved in the above embodiments are as follows: When staff need to inspect the surface defects of aluminum-zinc-silicon coated steel sheets, they first place the sheet on the inspection table 2. Then, they fix the sheet to the upper surface of the inspection table 2 using the existing clamping mechanism. Based on the reflectivity of the aluminum-zinc-silicon coated surface, they rotate knob 418, causing threaded rod 417 to rotate. Threaded rod 417 is connected to one of the sliders 410, allowing one slider 410 to slide horizontally within the through groove 409. Since linkage plates 411 connect both sides of the two sliders 410, the movement of one slider 410 will pull the other slider 410 to move synchronously via the linkage plates 411. As the two sliders 410 move synchronously, they will also drive the ring 415 to move synchronously via the vertical plate 414 connected to the upper surface. This causes the lifting rod 416, which is slidably connected to the ring 415, to slide along the upper surface of the limiting plate 408. Because the upper surface of the limiting plate 408 is inclined, and the two… The limiting plates 408 are symmetrically distributed. Therefore, when one of the lifting rods 416 rises along the upper surface of the limiting plate 408, it will pull the other lifting rod 416 downwards along the lower surface of the limiting plate 408 through the ring 415, vertical plate 414, slider 410, and linkage plate 411. At this time, the two lifting rods 416 cooperate with each other, which will push the detection table 2, which is attached to the upper surface of the lifting rod 416, to tilt. This causes the detection table 2 to drive the universal ball 402 connected to the lower surface to rotate within the connecting ball 403. The tilt angle of the aluminum-zinc-silicon plate material placed on the upper surface of the inspection table 2 is changed to facilitate the inspection of the surface of the aluminum-zinc-silicon plate material by the vision inspection instrument 3. This not only allows for quick changes in the tilt angle of the inspection table 2, making operation convenient, but also enables timely adjustment of the angle according to the reflectivity of the aluminum-zinc-silicon plate surface, improving inspection preparation efficiency. Furthermore, the angle of the inspection table 2 can be flexibly adjusted according to the reflectivity of the aluminum-zinc-silicon plate surface, avoiding the inability of the vision inspection instrument 3 to clearly capture surface defects due to reflection problems, thus ensuring the accuracy and comprehensiveness of the inspection. When adjusting the tilt angle of the testing platform 2, the front end of the testing platform 2 is tilted downwards first. This causes the testing platform 2 to press against the contact plate 509 on its lower end, causing the lifting block 503 connected to the side wall of the contact plate 509 to slide downwards within the connecting groove 502 on the support plate 501. The lifting block 503 then pulls the lifting column 506 connected to its upper end into the support plate 501. Since a disc 508 is connected to the upper end of the lifting column 506, and a second spring 507 connects the disc 508 and the support plate 501, as the lifting column 506 descends, it causes the disc 508 to descend synchronously, compressing the second spring 507. During the descent of the lifting block 503, the lifting block 503 drives the pointers 506 connected to both sides to descend. 04. Simultaneously descend, and the scale bar 505 pointed to by pointer 504 is changed. At this time, the staff can accurately control the descent distance of the lifting block 503 by observing the scale bar 505 pointed to by pointer 504. Since the descent of the lifting block 503 is caused by the tilt of the detection table 2 pressing the contact plate 509, the tilt angle of the detection table 2 can be accurately adjusted by controlling the descent distance of the lifting block 503. This not only makes the descent distance of the lifting block 503 visible, but also allows the staff to accurately control the descent distance according to the scale, thereby accurately adjusting the tilt angle of the detection table 2 to meet the high-precision detection requirements. Moreover, the precise tilt angle adjustment can ensure that the aluminum zinc silicon plate is at a suitable and consistent angle during each test, reducing the detection error caused by angle differences and ensuring the consistency and reliability of the test results. After the testing platform 2 moves away from the contact plate 509, the second spring 507 connected between the disc 508 and the support plate 501 automatically pushes the disc 508 away from the support plate 501, pulling the lifting block 503 connected to the lower end of the disc 508 to rise automatically in the connecting groove 502, and causing the contact plate 509 connected to the side wall of the lifting block 503 to return to the initial position. The automatic reset function not only ensures that the contact plate 509 returns to the initial position accurately every time, avoiding the deviation that may occur during manual reset and ensuring the consistency and stability of the testing conditions, but also eliminates the need for manual reset of the contact plate 509, relying on the spring rebound force to complete the reset automatically, saving operation time and manpower, and making the testing process more compact and efficient. After the tilt angle of the aluminum-zinc-silicon plate material on the testing table 2 is adjusted, the operator can lift the handle 419 upwards, causing the locking pin 420 to slide vertically upwards on the connecting plate 401. This allows the locking pin 420 to slide out from one of the locking holes 422 on the upper surface of the workbench 1. Simultaneously, the first spring 421 connected between the handle 419 and the connecting plate 401 is pulled. After the locking pin 420 is completely separated from the locking hole 422, the operator can horizontally move the handle 419, causing the connecting plate 401 to move horizontally via the locking pin 420. This causes the rack plate 406 connected to the side wall of the connecting plate 401 to move synchronously. At this time, the rack plate 406 slides horizontally on the workbench 1 through the sliding plate 407 and the sliding groove 6 connected to its lower end face. Since the rack plate 406 is meshed with the transmission gear 405, and the transmission gear 405 is rotatably connected to the outer surface of the support column 404, the rack plate 406 slides horizontally on the workbench 1 via the sliding plate 407. When the device slides to the other side, it can rotate the transmission gear 405 one revolution on the outer surface of the support column 404. At this time, as the transmission gear 405 rotates, it will drive the lifting rod 416 to rotate synchronously against the lower end face of the inspection table 2 through the limiting plate 408. Due to the different heights of the lifting rods 416 on both sides, the inspection table 2 is initially tilted. Therefore, during the rotation of the lifting rod 416, it will push the inspection table 2 to continuously change its tilt direction, so that the vision inspection instrument 3 can inspect the surface of the aluminum-zinc-silicon plate material fixed on the upper end face of the inspection table 2 from different angles. This not only allows the vision inspection instrument 3 to inspect the surface of the aluminum-zinc-silicon plate from multiple different angles, effectively avoiding blind spots and improving the comprehensiveness of the inspection, but also enables the continuous change of the angle of the inspection table 2 quickly, without the need to repeatedly manually adjust the fixing device to change the inspection angle, reducing the downtime during the inspection process and thus improving the overall inspection efficiency. As the two lifting rods 416 rotate continuously, changing the tilt angle of the inspection table 2, the upper end face of the transmission gear 405 is connected to the side plate 412, and the upper end face of the side plate 412 is connected to the auxiliary rod 413. Therefore, as the transmission gear 405 rotates, the side plate 412 can drive the auxiliary rod 413 to move synchronously against the lower end face of the inspection table 2, thereby improving the stability of the inspection table 2 during the movement. This not only reduces the inspection deviation caused by shaking and vibration, ensuring that the vision inspection instrument 3 can accurately capture the surface defect information of the aluminum zinc silicon plate and improve the accuracy of the inspection results, but also makes the inspection process smoother due to the stable movement of the inspection table 2. It eliminates the need to frequently pause the inspection for adjustment due to equipment instability, which helps to improve the overall inspection efficiency. When the operator moves the handle 419, the rack plate 406 moves from one side to the other via the locking pin 420 and the connecting plate 401. The operator can then release the handle 419. The rebound force of the first spring 421 connected between the handle 419 and the connecting plate 401 causes the handle 419 to automatically descend and approach the connecting plate 401, pushing the locking pin 420 to slide downward on the connecting plate 401 and engage with another locking hole 422 on the upper surface of the worktable 1. This fixes the positions of the connecting plate 401 and the rack plate 406. The rack plate 406 meshes with the transmission gear 405, which simultaneously limits the positions of the lifting rod 416 and the auxiliary rod 413 connected to the transmission gear 405, thereby maintaining the stability of the testing table 2 supported above the lifting rod 416 and the auxiliary rod 413.
