Description

Technical Field

[0001] This invention relates to the field of aluminum product appearance inspection equipment, and in particular to an aluminum product appearance inspection equipment and method based on visual inspection. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. It involves using machine vision products to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. It is a valuable mechanism for production, assembly, or packaging, and it has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0003] In the automotive parts industry, visual inspection is used to detect cracks, scratches, missing parts, and stains on the appearance of aluminum products. However, some existing large aluminum die-cast shells, due to their irregular shapes, generally only have two flat ends. This means that visual inspection can only be performed with the two flat ends as the shells are flat. When side inspection is required, multiple visual detectors at different angles are needed. This requires multiple stations to inspect the shells, which takes up a large area of ​​equipment and the inspection results are not satisfactory. Alternatively, a robotic arm can be used to drive the visual inspection instrument to scan the sides of the shell. This requires multiple sets of complex programming for the robotic arm, which is prone to errors in program retrieval and collision risks. Furthermore, visual inspection cannot effectively detect some small cracks, which require subsequent sealing processes. Therefore, we propose a visual inspection-based aluminum product appearance inspection equipment and method. Summary of the Invention

[0019] A method for using a visual inspection-based aluminum product appearance inspection device includes the following steps:

[0020] During inspection, the robotic arm clamps the housing component and places it on the upper part of the worktable, with the first cavity corresponding to the position of the second sealing block. A vision inspection instrument inspects the front of the housing component and determines if its position needs adjustment. If adjustment is required, the first electric slide, third electric cylinder, and fourth electric cylinder adjust the second mounting block's position along three axes. The first electric telescopic rod pushes the clamping plate to rotate on the side of the second mounting block, clamping and adjusting the housing component's position. The second electric cylinder pushes the second sealing block upwards to its position inside the first cavity. The second air pump supplies air through the third air pipe, causing the second sealing airbag to expand and seal against the inner wall of the first cavity. Then, the first electric cylinder pushes the movable sleeve to slide inside the mounting groove. Simultaneously, the movable sleeve's circular block slides and is constrained within the constraint groove, causing the movable rod to slide within the movable sleeve. Adjusting the worktable causes the housing component to tilt at a 15-degree angle. The second motor drives the rotating plate to rotate, causing the movable rod to rotate and slide within the movable sleeve. Simultaneously, the constraint frame, constraint block, and constraint rod form a universal joint, causing the third motor to perform a oscillating circular motion. Thus, the worktable moves the housing component... The multi-angle pauses allow the four sides of the housing to be inspected by a visual inspection instrument. After completion, the rotating plate is reset, and the first electric cylinder pulls the movable sleeve to reset, making the worktable horizontal. The first motor drives the connecting block to rotate 180 degrees, so that the first air pump and the first sealing block are perpendicular to the housing. The three-axis manipulator on the upper side of the first mounting block drives the first sealing block to extend into the first cavity. The first air pump supplies air through the first air pipe, causing the first sealing airbag to expand and seal the inner wall of the first cavity. The second air pump supplies air through the second air pipe, and the pressure sensor reads the pressure value inside the first cavity for sealing detection. After completion, the second sealing block, the first sealing block, and the visual inspection instrument are reset. Then, the visual inspection instrument assists the clamping plate to clamp the housing. The fourth motor drives the housing to rotate 180 degrees. The first electric slide, the third electric cylinder, and the fourth electric cylinder work together to place the housing in the second cavity corresponding to the position of the second sealing block. The reverse side of the housing is inspected in the same way. The second sealing block rises to expand and seal the inner wall of the housing. The drive module drives the housing to cooperate with the visual inspection instrument for multi-angle inspection.

[0021] When the inspection is passed, the visual inspection instrument's auxiliary clamping plate clamps the housing component. Similarly, the drive module tilts the worktable to a 30-degree angle. When the photoelectric sensor detects the conveyor line, the telescopic component pushes the clamping plate to engage inside the mating plate. The clamping plate holds the housing component and slides it to the rotating platform position via the first electric slide. Simultaneously, the fixing rod slides to the corresponding position on the side of the fourth electric slide according to the position of the second mounting block, aligning the limit rod with the housing component. The clamping plate releases the housing component, which rolls onto the first and second roller shafts to the transition slide for buffering. The limit rod slides down to the side of the conveyor line, reaching the limit block position. Once the limit position is reached and the housing component is in place, the clamping plate and worktable are reset for inspection. The sixth electric cylinder slides to the position of the housing component on the side of the third electric slide, and the adjustable gripper position is extended and adjusted. After the adjustable gripper clamps the housing component, the fourth electric slide drives the second electric slide to reset to the positions of both ends of the movable plate. Then, the second electric telescopic rod pulls the limit rod to a position close to the side of the movable plate. The fifth electric cylinder and the second electric slide work together to drive the movable plate to slide to the stacking plate position. The sixth electric cylinder and the adjustable gripper work together to place the housing component on the upper part of the stacking plate. The hydraulic assembly lowers the stacking plate and replaces the stacking plate through the robotic arm. After that, the hydraulic assembly resets it.

[0022] When the inspection determines that it can be repaired, the same clamping plate clamps the housing part, the third motor drives the rotating table to rotate, and the drive module drives the worktable to tilt at a 30-degree angle. Through the same operation as the first group above, the second group of material conveying modules receives and stacks the housing part to the subsequent repair process. The drive module, worktable module and clamping module are reset and the above inspection operation is repeated.

[0023] When the inspection determines that the part is unrepairable, the clamping plate holds the housing part, the third motor drives the rotating table to rotate to the collection box position, the drive module drives the worktable to tilt at a 30-degree angle to the guide plate position, the clamping plate is released so that the housing part slides to the side of the first roller shaft into the collection box for collection, and the drive module, worktable module and clamping module are reset and the above inspection operation is repeated.

[0024] Beneficial effects

[0025] This invention provides a visual inspection device and method for inspecting the appearance of aluminum products, which has the following beneficial effects:

[0026] (1) The visual inspection equipment and method for aluminum products uses internal components of the housing module, workbench module, drive module, and clamping module for inspection. The robotic arm clamps the housing part and places it on the upper side of the workbench. The first cavity corresponds to the position of the second sealing block. The second electric cylinder pushes the second sealing block upward to the position inside the first cavity. The second air pump supplies air through the third air pipe to make the second sealing airbag expand and seal the position of the second sealing airbag on the inner wall of the first cavity. The first electric cylinder pushes the movable sleeve to slide inside the mounting groove. At the same time, the movable sleeve block slides inside the constraint groove and is constrained, causing the movable rod to slide inside the movable sleeve. The workbench is adjusted to make the housing part tilted at 15 degrees. The second motor drives the rotating plate to rotate, causing the movable rod to rotate and slide inside the movable sleeve. At the same time, the constraint frame, constraint block, and constraint rod are in a universal joint manner, causing the third motor to swing in a circular motion. In this way, the workbench moves the housing part to stop at multiple angle positions, so that the four sides of the housing part can be inspected by the visual inspection instrument. After completion, the workbench is reset to a horizontal position. The first motor drives the connecting block to rotate 180 degrees, so that the first air pump and the first The sealing block is perpendicular to the housing component. A three-axis robotic arm on the upper side of the first mounting block extends the first sealing block into the first cavity. A first air pump supplies air through a first air pipe, causing the first sealing airbag to expand and seal the inner wall of the first cavity. A second air pump supplies air through a second air pipe inside the first cavity. A pressure sensor reads the pressure value for sealing detection. After completion, the second sealing block, the first sealing block, and the vision inspection instrument are reset. Then, the vision inspection instrument assists the clamping plate to clamp the housing component. A fourth motor drives the housing component to rotate 180 degrees. The first electric slide, the third electric cylinder, and the fourth electric cylinder work together to place the housing component in the second cavity corresponding to the position of the second sealing block. The reverse side of the housing component is inspected in the same way. The second sealing block rises to expand and seal the inner wall of the housing component. The drive module drives the housing component to cooperate with the vision inspection instrument for multi-angle inspection. This achieves comprehensive appearance inspection of the housing component at the same station and assists in the sealing detection of the housing component cavity, improving the inspection effect and efficiency of the housing component. The equipment is also more centralized, reducing the floor space and avoiding the risk of collision between the robotic arm and the vision detector.

[0027] (2) The visual inspection-based aluminum product appearance inspection equipment and method, through the cooperation of internal components of the workbench module, drive module, clamping module, material conveying module and scrap module, when the inspection is qualified, after the inspection is completed, the visual inspection instrument auxiliary clamping plate clamps the housing part, the drive module drives the workbench plate to tilt at a 30-degree angle, when the photoelectric sensor detects the conveyor line, the telescopic component pushes the clamping plate to engage with the position inside the mating plate, the clamping plate clamps the housing part and slides to the position of the rotating table through the first electric slide, at the same time the fixing rod slides to the corresponding position on the side of the fourth electric slide according to the position of the second mounting block, so that the position of the limiting rod and the housing part correspond, the limiting rod slides down to the side of the conveyor line and reaches the position of the limiting block to achieve the limiting, at the same time, after the housing part is detected to be in place, the clamping plate and the workbench plate reset to perform the inspection operation, and the sixth electric cylinder slides to the position of the housing part on the side of the third electric slide for telescopic adjustment. The adjustable gripper position allows the fourth electric slide to drive the second electric slide to return to the positions at both ends of the movable plate after clamping the housing part. The second electric telescopic rod pulls the limit rod to a position close to the side of the movable plate. The fifth electric cylinder and the second electric slide work together to drive the movable plate to the stacking plate position. The sixth electric cylinder and the adjustable gripper work together to place the housing part on the upper part of the stacking plate. The hydraulic component lowers the stacking plate. After the stacking plate is replaced by the robotic arm, the hydraulic component resets it. When the housing part is repairable, the third motor drives the rotating table to rotate, and other operations are the same as above. When the housing part is not repairable, the third motor drives the rotating table to rotate to the collection box position. The drive module drives the worktable to tilt at a 30-degree angle to the guide plate position. The clamping plate is released, allowing the housing part to slide to the side of the first roller shaft and be collected inside the collection box. In this way, the tested housing parts can be classified and stacked according to the test results for subsequent processes. Attached Figure Description

[0058] A method for using a visual inspection-based aluminum product appearance inspection device includes the following steps:

[0059] During inspection, the robotic arm clamps the housing module 1 to the workbench module 4. Visual inspection is performed by the detection module 2. The drive module 3 adjusts the angle of the housing module 1 to cooperate with the detection module 2. The clamping module 5 clamps and flips the housing module 1 to cooperate with the detection module 2. The workbench module 4 and the detection module 2 perform a sealing inspection on the combined housing module 1. The drive module 3 and the clamping module 5, together with the material conveying module 6 and the waste module 7, sort and feed the housing module 1. Specifically, the robotic arm clamps the housing component 11 and places it on the upper side of the workbench plate 42, with the first cavity 12 corresponding to the position of the second sealing block 43. The front of the housing component 11 is inspected by the visual inspection instrument 24. Simultaneously, the visual inspection instrument 24 determines whether the position of the housing component 11 needs adjustment. If adjustment is required, the first electric slide 51, the third electric cylinder 52, and the fourth electric cylinder 53 are used to adjust the position of the second sealing block 43. The second mounting block 55 adjusts the three-axis position. The first electric telescopic rod 551 pushes the clamping plate 56 to rotate on the side of the second mounting block 55, clamping and adjusting the position of the housing 11. The fifth motor 562 drives the mating rod 563 to rotate, causing the clamping block 564 to engage with its thread. The clamping block 564 slides within the movable groove 561 to adjust its position. The dustproof plate 565 provides dust protection. The second electric cylinder 434 pushes the second sealing block 43 upward to its position inside the first cavity 12. The second air pump 433 supplies air through the third air pipe 437, causing the second sealing airbag 432 to expand and seal against the inner wall of the first cavity 12. Then, the first electric cylinder 333 pushes the movable sleeve 334 to slide within the mounting groove 331. Simultaneously, the circular block of the movable sleeve 334 slides within the constraint groove 332, constraining the movable rod 351 to slide within the movable sleeve 334. Thus... Figure 16As shown, adjusting the worktable 42 causes the housing 11 to tilt at a 15-degree angle, allowing the vision inspection instrument 24 to inspect the sides of the housing 11. The second motor 32 drives the rotating plate 33 to rotate, causing the movable rod 351 to rotate and slide inside the movable sleeve 334. Simultaneously, the constraint frame 34, constraint block 341, and constraint rod 342 form a universal joint, causing the third motor 35 to swing in a circular motion. This allows the worktable 42 to stop the housing 11 at multiple angles, enabling the vision inspection instrument 24 to inspect all four sides of the housing 11. After completion, the rotating plate 33 resets, and the first electric cylinder 333 pulls the movable sleeve 334 back to its original position, making the worktable 42 horizontal. The first motor 22 drives the connecting block 23 to rotate 180 degrees, causing the first air pump 25 and the first sealing block 26 to be perpendicular to the housing 11. The three-axis manipulator on the upper side of the first mounting block 21 then extends the first sealing block 26 to... Inside the first cavity 12, the first air pump 25 supplies air through the first air pipe 263, causing the first sealing airbag 262 to expand and seal at the position of the inner wall of the first cavity 12. The second air pump 433 supplies air through the second air pipe 436 inside the first cavity 12. The pressure sensor 435 reads the pressure value to perform a sealing test. After completion, the second sealing block 43, the first sealing block 26 and the vision inspection instrument 24 are reset. Then, the vision inspection instrument 24 assists the clamping plate 56 to clamp the housing part 11. The fourth motor 54 drives the housing part 11 to rotate 180 degrees. The first electric slide 51, the third electric cylinder 52 and the fourth electric cylinder 53 cooperate to place the housing part 11 in the second cavity 13 corresponding to the position of the second sealing block 43. The reverse side of the housing part 11 is inspected in the same way. The second sealing block 43 rises to expand and seal the inner wall of the housing part 11. The drive module 3 drives the housing part 11 to cooperate with the vision inspection instrument 24 for multi-angle inspection.

[0060] When the inspection is passed, the drive module 3 drives the worktable module 4 to offset the angle and align with the material feeding module 6. The clamping module 5 clamps the housing module 1 to assist in unloading. Specifically, after the inspection is completed, the visual inspection instrument 24 assists the clamping plate 56 to clamp the housing part 11, as above. Figure 16As shown, the drive module 3 drives the worktable 42 to tilt at a 30-degree angle. When the photoelectric sensor 442 detects the conveyor line 61, the telescopic component 451 pushes the clamping plate 452 to engage with the position inside the mating plate 611. The clamping plate 56 holds the housing part 11 and slides it to the position of the rotating table 41 via the first electric slide 51. At the same time, the fixing rod 671 slides to the corresponding position on the side of the fourth electric slide 67 according to the position of the second mounting block 55, so that the position of the limiting rod 673 corresponds to the position of the housing part 11. The clamping plate 56 releases the housing part 11 and rolls it on the first roller shaft 44 and the second roller shaft 612 to the transition slide plate 613 for transition buffering. It slides down to the side of the conveyor line 61 under the limit of the limiting rod 673 and reaches the position of the limiting block 674 to achieve the limit. At the same time, after detecting that the housing part 11 is in place, the clamping plate 452... The worktable 42 is reset for testing. The sixth electric cylinder 661 slides to the position of the housing 11 on the side of the third electric slide 66 and extends and adjusts the position of the adjustable gripper 662. After the housing 11 is clamped by the adjustable gripper 662, the fourth electric slide 67 drives the second electric slide 63 to reset to the positions of both ends of the movable plate 65. The second electric telescopic rod 672 pulls the limit rod 673 to a position close to the side of the movable plate 65. The fifth electric cylinder 64 and the second electric slide 63 work together to drive the movable plate 65 to slide to the position of the stacking plate 62. The sixth electric cylinder 661 and the adjustable gripper 662 work together to place the housing 11 on the upper position of the stacking plate 62. The hydraulic component 621 lowers the stacking plate 62. After the mechanical arm replaces the stacking plate 62, the hydraulic component 621 resets it.

[0061] When the inspection determines that the part is repairable, the same clamping plate 56 clamps the housing component 11 as above. Figure 17 As shown, the third motor 35 drives the rotating table 41 to rotate, and the drive module 3 drives the worktable 42 to tilt at a 30-degree angle. Through the same operation as the first group above, the second group of material conveying modules 6 receives and stacks the housing parts 11 to the subsequent repair process.

[0062] When the test determines that it is irreparable, the clamping plate 56 clamps the housing part 11, the third motor 35 drives the rotating table 41 to rotate to the position of the collection box 72, the drive module 3 drives the worktable 42 to tilt at a 30-degree angle to the position of the guide plate 71, and the clamping plate 56 is released so that the housing part 11 slides to the side of the first roller 44 and is collected inside the collection box 72.

9. A method of using the visual inspection-based aluminum product appearance inspection equipment as described in claim 1, characterized in that, Includes the following steps: During inspection, the robotic arm clamps the housing component (11) and places it on the upper side of the worktable (42). The first cavity (12) corresponds to the position of the second sealing block (43). The vision inspection instrument (24) inspects the front of the housing component (11). Based on the vision inspection instrument (24), it is determined whether the position of the housing component (11) needs to be adjusted. If adjustment is required, the first electric slide (51), the third electric cylinder (52), and the fourth electric cylinder (53) adjust the position of the second mounting block (55) in three axes. The first electric telescopic rod (551) pushes the clamping plate (56) to rotate on the side of the second mounting block (55) to clamp and adjust the position of the housing component (11). The second electric cylinder (434) pushes the second sealing block (43) upward to move into the first cavity (12). At the first position, the second air pump (433) supplies air through the third air pipe (437) to inflate and seal the second sealing airbag (432) on the inner wall of the first cavity (12). Then, the first electric cylinder (333) pushes the movable sleeve (334) to slide inside the mounting groove (331). At the same time, the circular block of the movable sleeve (334) slides inside the constraint groove (332) and is constrained, causing the movable rod (351) to slide inside the movable sleeve (334). The adjusting worktable plate (42) drives the housing part (11) to tilt at a 15-degree angle. The second motor (32) drives the rotating plate (33) to rotate, causing the movable rod (351) to rotate and slide inside the movable sleeve (334). At the same time, the constraint frame (34), constraint block (341), and constraint rod (34) are also affected. 2) The universal joint design allows the third motor (35) to swing in a circular motion, so that the worktable (42) drives the housing (11) to stop at multiple angles, allowing the four sides of the housing (11) to be inspected by the visual inspection instrument (24). After completion, the rotating plate (33) is reset, and the first electric cylinder (333) pulls the movable sleeve (334) to reset, so that the worktable (42) is horizontal. The first motor (22) drives the connecting block (23) to rotate 180 degrees, so that the first air pump (25) and the first sealing block (26) are perpendicular to the housing (11). The three-axis manipulator on the upper side of the first mounting block (21) drives the first sealing block (26) to extend into the first cavity (12). The first air pump (25) is powered by the first air pipe (26). 3) The air supply causes the first sealing airbag (262) to expand and seal the inner wall of the first cavity (12). The second air pump (433) supplies air to the inside of the first cavity (12) through the second air pipe (436). The pressure value is read by the pressure sensor (435) for sealing detection. After completion, the second sealing block (43), the first sealing block (26) and the visual inspection instrument (24) are reset. Then, the visual inspection instrument (24) assists the clamping plate (56) to clamp the housing part (11). The fourth motor (54) drives the housing part (11) to rotate 180 degrees. The first electric slide (51), the third electric cylinder (52) and the fourth electric cylinder (53) cooperate to place the housing part (11) in the second cavity (13) corresponding to the position of the second sealing block (43).The reverse side of the housing component (11) is inspected as described above. The second sealing block (43) rises to expand and seal the inner wall of the housing component (11). The drive module (3) drives the housing component (11) to cooperate with the visual inspection instrument (24) for multi-angle inspection. When the inspection is completed and the product is deemed qualified, the visual inspection instrument (24) and the auxiliary clamping plate (56) clamp the housing part (11). Similarly, the drive module (3) drives the worktable plate (42) to tilt at a 30-degree angle. When the photoelectric sensor (442) detects the conveyor line (61), the telescopic component (451) pushes the clamping plate (452) to engage with the position inside the mating plate (611). The clamping plate (56) clamps the housing part (11) and slides it to the rotary table via the first electric slide (51). At the same time, the fixing rod (671) slides to the corresponding position on the side of the fourth electric slide table (67) according to the position of the second mounting block (55), so that the position of the limiting rod (673) and the housing part (11) correspond. The clamping plate (56) releases the housing part (11) and rolls on the side of the first roller shaft (44) and the second roller shaft (612) to the transition slide plate (613) for transition buffering. The limiting rod (673) slides down to the side of the conveyor line (61) and reaches the position of the limiting block (674). When the limit is reached, and the housing part (11) is in place, the clamping plate (452) and the worktable (42) are reset to perform the detection operation. The sixth electric cylinder (661) slides on the side of the third electric slide (66) to the position of the housing part (11) and extends and adjusts the position of the adjustable gripper (662). After the adjustable gripper (662) clamps the housing part (11), the fourth electric slide (67) drives the second electric slide (63) to reset to the positions of both ends of the movable plate (65). Then the second electric telescopic rod (672) is activated. The limit rod (673) is pulled to a position close to the side of the movable plate (65). The fifth electric cylinder (64) and the second electric slide (63) work together to drive the movable plate (65) to slide to the position of the stacking plate (62). The sixth electric cylinder (661) and the adjustable gripper (662) work together to place the housing part (11) on the upper side of the stacking plate (62). The hydraulic component (621) lowers the stacking plate (62) and replaces the stacking plate (62) through the robotic arm. After that, the hydraulic component (621) resets it. When the test determines that it can be repaired, the same clamping plate (56) clamps the housing part (11), the third motor (35) drives the rotating table (41) to rotate, and the drive module (3) drives the worktable (42) to tilt at a 30-degree angle. Through the same operation as the first group above, the second group of material conveying modules (6) receives the housing part (11) and stacks it to the subsequent repair process. The drive module (3), the worktable module (4) and the clamping module (5) are reset and the above test operation is repeated. When the test determines that the part is unrepairable, the clamping plate (56) clamps the housing part (11), the third motor (35) drives the rotating table (41) to rotate to the position of the collection box (72), the drive module (3) drives the worktable (42) to tilt at a 30-degree angle to the position of the guide plate (71), the clamping plate (56) is released so that the housing part (11) slides to the side of the first roller (44) and is collected inside the collection box (72). The drive module (3), the worktable module (4) and the clamping module (5) are reset and the above test operation is repeated.
