Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and more specifically to a multi-axis rotating area array visual inspection device. Background Technology

[0002] With the continuous improvement of industrial automation, visual inspection devices are playing an increasingly crucial role in the manufacturing sector, particularly in the strict control of product quality and the optimization of production process efficiency. Depending on the actual needs of the inspection object and the scenario, engineers can flexibly choose to deploy either area scan cameras or line scan cameras as the two main imaging devices to achieve effective monitoring and automated judgment of key quality indicators such as product appearance defects and dimensional accuracy.

[0003] Patent CN218382455U discloses a visual inspection device that uses a vision device to inspect objects on a conveying device, eliminating the need for manual inspection and improving inspection efficiency and accuracy. However, current visual inspection systems, when inspecting products such as powder-molded products (e.g., sintering release agent residue in powder metallurgy gears), machined metal parts (e.g., microburrs on metal stampings), polymer products (e.g., flash and burrs on injection-molded shells), and food products (e.g., nut and fruit peel fragments), suffer from significant blind spots, as visual inspection is essentially a device that replaces human observation. When dealing with products with complex curved surfaces, multi-angle, or three-dimensional structures, traditional visual inspection systems have large blind spots. Furthermore, debris and other contaminants often detach from the products, obstructing visual inspection and causing the device to fail to identify objects accurately or even misjudge them, thus limiting its effectiveness. Summary of the Invention

[0004] One of the objectives of this invention is to provide a multi-axis rotating area array visual inspection device to solve the technical problem in the prior art that there are blind spots in the inspection when visual inspection equipment faces products with complex curved surfaces, multiple angles, or three-dimensional structures.

[0005] The second objective of this invention is to provide a multi-axis rotating area array visual inspection device to solve the technical problem in the prior art where the vision of the area array camera is limited when some attached debris falls off the inspected product, causing the device to fail to identify it properly or even make a misjudgment.

[0007] Preferably, the cleaning liquid is stored inside the sponge block near the flat suction nozzle. The cleaning liquid is then delivered to the cloth on it. When the glass plate passes by the cloth, its surface is cleaned. Afterward, the cleaning liquid coated on the glass plate is absorbed by the cloth on the side away from the flat suction nozzle, and then stored by the sponge block on it.

[0008] Preferably, a first annular groove is formed in the middle of the inner wall of the outer ring; a second annular groove is formed in the middle of the outer wall of the inner ring; and multiple rollers are rolled together in the first annular groove and the second annular groove.

[0009] Preferably, the plurality of rollers are arranged at equal intervals inside the first and second annular grooves via annular plates; the inner ring protrudes from one side of the outer ring and is symmetrically provided with a mounting part, and the area array camera is fixedly mounted inside the mounting part.

[0010] Preferably, a driven gear ring is fixedly provided on the other side of the inner ring protruding from the outer ring; an adjusting motor is fixedly provided on the upper part of the outer ring; and a driving gear is fixedly connected to the output end of the adjusting motor.

[0011] Preferably, the motor drives the inner ring to rotate inside the outer ring through a drive gear and a drive gear ring, so that the area scan camera located above the glass plate and the area scan camera located below the glass plate move to the left and right sides or the top and bottom sides of the product, respectively.

[0012] Preferably, a first connecting shaft is fixedly connected to both sides of the outer ring, and the outer ring is rotatably connected to the I-beam through the first connecting shaft; a servo motor is fixedly mounted on one of the I-beams via a fixing plate; a second bevel gear is fixedly connected to the output end of the servo motor; and a first bevel gear is fixedly connected to the end of the first connecting shaft near the second bevel gear.

[0013] Preferably, the servo motor drives the outer ring to rotate around the Y-axis, causing the area scan camera located above the glass plate and the area scan camera located below the glass plate to move to the front and rear sides of the product, respectively.

[0014] Preferably, the lower part of the flat suction nozzle is connected to a plurality of evenly distributed soft suction branches; the outer ends of the suction branches are connected to a main suction pipe, which is connected to the vacuum cleaner.

[0015] Preferably, the inner ring is also fixedly connected to a voice coil motor via a bracket at the position corresponding to the area scan camera. The output end of the voice coil motor is connected to the tail end of the area scan camera, and the area scan camera is moved in the Z-axis direction by the voice coil motor.

[0016] The multi-axis rotating array vision inspection device includes the following usage steps: S100: First, based on the volume of the product to be inspected, the Z-axis direction of the array camera is adjusted using a voice coil motor to adapt its detection focal length to the corresponding product to be inspected. S200: The drive motor drives the chain to rotate, and the chain rotates to move the transparent glass plate. The product to be tested is then placed on the glass plate and moves with the glass plate. S300: The product to be inspected is carried to the area scan camera using a glass plate. The area scan camera located above the glass plate and the area scan camera located below the glass plate first perform visual inspection on the upper and lower parts of the product. If it is not qualified, it is marked. Then, the area scan camera drives the inner ring and the area scan camera on the inner ring to rotate around the X-axis by adjusting the coordination of the motor, the drive gear and the driven gear. This allows the upper and lower area scan cameras to rotate to the two sides of the product, and then visual inspection is performed on the left and right sides. If the product is not qualified, it is marked. Finally, the area scan camera returns to its original position under the action of the adjustment motor. The servo motor drives the second bevel gear and the first bevel gear, so that the outer ring rotates around the Y-axis. The inner ring and the area scan camera set on it rotate accordingly, so that the two area scan cameras move to the front and rear positions of the product to be inspected to perform visual inspection. If it is unqualified, it is marked.

[0017] S400: The glass plate continues to move carrying the inspected products, and qualified and unqualified products are removed from the glass plate respectively; S500: The glass plate continues to move with the chain until it reaches the flat suction nozzle. The vacuum cleaner, the main suction pipe and the branch suction pipe work together to suck away the debris and debris attached to the surface of the glass plate, so as to avoid the accumulation of debris and debris affecting the normal detection of the area scan camera. S600: The glass plate continues to move along the chain and passes through two wiping cloth positions. When it passes through the first wiping cloth position, the cleaning liquid is delivered to the wiping cloth through the sponge block that stores the cleaning liquid, and the surface of the glass plate is cleaned. Then, when it passes through the second wiping cloth position, the cleaning liquid on the surface of the glass plate is wiped off with a dry wiping cloth to ensure the transparency of the glass plate and so that the area scan camera always maintains a good detection effect. S700: The glass plate continues to move along the chain and performs continuous visual inspection.

[0018] The beneficial effects of this invention are: The multi-axis rotating area array visual inspection device provided by this invention uses a laser sensor as a feedback element to instruct the operation of each motor, so that the area array camera rotates or moves in the X, Y, and Z axes, thereby realizing the multi-axis adjustment function of the area array camera. When inspecting products, by using area array cameras symmetrically arranged above and below the glass plate, the product is visually inspected simultaneously through the glass plate, resulting in high inspection efficiency, no blind spots, and good inspection effect.

[0019] This invention, in conjunction with a flat suction nozzle and two cloths with sponge blocks, can clean residue adhering to the surface of a glass plate, ensuring the transparency of the glass plate and thus guaranteeing the visual inspection effect of the area scan camera, preventing misjudgments.

[0020] 3. If only one of the front, back, left, right, top, or bottom surfaces of the product to be inspected needs to be inspected, the position of the area array camera can be directly adjusted to a fixed position using a servo motor or an adjustable motor. If the product is irregular, the position of the area array camera can be adjusted using a servo motor or an adjustable motor so that it is exactly aligned with the area to be inspected. This invention has many application scenarios and a wide range of applications. Attached Figure Description

[0028] Please refer to it again. Figure 6 and Figure 7 As shown, when it is necessary to deflect the X-axis angle of the area array camera 21 to perform visual inspection on the left and right sides and the top and bottom sides of the product, the following components can be used for adjustment: a driven gear ring 26 is fixedly installed on the other side of the inner ring 15 protruding from the outer ring 9; a fixed ring 23 is fixedly installed on the upper part of the outer ring 9; an adjustment motor 24 is fixedly installed inside the fixed ring 23; a drive gear 25 is fixedly connected to the output end of the adjustment motor 24, and the adjustment motor 24 drives the inner ring 15 to rotate inside the outer ring 9 through the drive gear 25 and the drive gear ring, so that the area array camera 21 located above the glass plate 6 and the area array camera 21 located below the glass plate 6 respectively perform visual inspection on the left and right sides or the top and bottom sides of the product.

[0029] Please refer to it again. Figure 6 and Figure 7 As shown, when it is necessary to deflect the Z-axis angle of the area array camera 21 to perform visual inspection on the front and back sides of the product, the following specific components can be used for adjustment: a first connecting shaft 10 is fixedly connected to both sides of the outer ring 9, and the outer ring 9 is rotatably connected to the I-beam 8 through the first connecting shaft 10; a servo motor 13 is fixedly mounted on one of the I-beams 8 via a fixing plate 14; a second bevel gear 12 is fixedly connected to the output end of the servo motor 13; a first bevel gear 11 is fixedly connected to the end of the first connecting shaft 10 near the second bevel gear 12, and the first bevel gear 11 and the second bevel gear 12 mesh with each other.

[0030] Please refer to it again. Figure 6 and Figure 7As shown, when it is necessary to adjust the Z-axis height of the array camera 21 so that its detection focal length can be flexibly adjusted according to the actual detection requirements, it can be adjusted through the following specific components: The inner ring 15 is also fixedly connected to the position of the array camera 21 via a bracket, and the output end of the voice coil motor 22 is connected to the tail end of the array camera 21. The voice coil motor 22 causes the array camera 21 to move in the Z-axis direction to complete the detection focal length adjustment.

[0031] Please refer to it again. Figure 3 and Figure 4 As shown, a fixing plate 30 is fixedly connected to the L-shaped steel plate 34 at the bottom; a flat suction nozzle 29 is fixedly installed on the fixing plate 30, with the opening end of the flat suction nozzle 29 facing the glass plate 6; the lower part of the flat suction nozzle 29 is connected to multiple evenly distributed soft suction branch pipes 28; the outer ends of the suction branch pipes 28 are connected to a main suction pipe 27, which is connected to a vacuum cleaner. Through the cooperation of the main suction pipe 27, the suction branch pipes 28 and the flat suction nozzle 29, the debris and debris attached to the glass plate 6 are sucked away, so as to avoid the accumulation of debris and debris affecting the normal detection of the area scan camera 21 and causing misjudgment.

[0032] Please refer to it again. Figure 3 and Figure 4 As shown, two magnetic suction plates 32 are magnetically connected to the L-shaped steel plate 34 at the bottom. Each magnetic suction plate 32 has a sponge block 31 fixedly connected to its lower part and a wiping cloth 33 fixedly connected to its upper part. The wiping cloth 33 abuts against each glass plate 6 it passes through. By storing cleaning fluid inside the sponge block 31 on the side near the flat suction nozzle 29, the cleaning fluid can be delivered to the wiping cloth 33 on it. When the glass plate 6 passes through the wiping cloth 33, it can clean its surface. Then, the wiping cloth 33 on the side away from the flat suction nozzle 29 sucks away the cleaning fluid coated on the glass plate 6, and then the sponge block 31 on it stores the fluid to avoid contamination. Through the combined use of the sponge block 31, the wiping cloth 33 and the magnetic suction plate 32, the surface of the glass plate 6 can be cleaned, preventing debris and debris adhering to the surface of the glass plate 6 from affecting the normal operation of the area scan camera 21.

[0033] To facilitate understanding of the above-mentioned technical solutions of the present invention, the working principle or operation method of the multi-axis rotating area array visual inspection device provided by the present invention will be described in detail below in actual processes: S100: First, based on the volume of the product to be inspected, the voice coil motor 22 is used to adjust the Z-axis direction of the array camera 21 so that its detection focal length is adapted to the corresponding product to be inspected.

[0034] S200: The drive motor 7 drives the chain 4 to rotate. During the rotation of the chain 4, the transparent glass plate 6 is moved. The product to be tested is then placed on the glass plate 6 and moves with the glass plate 6.

[0035] S300: The product to be inspected is moved to the area scan camera 21 using the glass plate 6. The area scan camera 21 located above the glass plate 6 and the area scan camera 21 located below the glass plate 6 first perform visual inspection on the upper and lower parts of the product. If it is not qualified, it is marked.

[0036] Then, the area scan camera 21 drives the inner ring 15 and the area scan camera 21 on the inner ring 15 to rotate around the X-axis by adjusting the cooperation of the motor 24, the drive gear 25 and the driven gear. This causes the upper and lower area scan cameras 21 to rotate to the two sides of the product respectively, and then visual inspection is performed on the left and right sides. If it is not qualified, it is marked. Finally, the area array camera 21 returns to its original position under the action of the adjustment motor 24. The servo motor 13 drives the second bevel gear 12 and the first bevel gear 11, so that the outer ring 9 rotates around the Y-axis. The inner ring 15 and the area array camera 21 set on it rotate accordingly, so that the two area array cameras 21 move to the front and rear positions of the product to be inspected to perform visual inspection. If it is unqualified, it is marked.

[0037] It is worth noting that if only one of the front, back, left, right, top, or bottom surfaces of the product to be inspected needs to be inspected, the position of the area scan camera 21 can be directly adjusted to a fixed position using the servo motor 13 or the adjusting motor 24. Similarly, when inspecting irregular products, the position of the area scan camera 21 can be adjusted using the servo motor 13 or the adjusting motor 24 so that it is precisely aligned with the area to be inspected. This method has many application scenarios and a wide range of applications.

[0038] The system utilizes position or distance feedback signals provided by a laser sensor (not shown in the figure, which is a feedback element used to measure key position parameters of the product under inspection in real time and accurately) to form a closed-loop control system. This system precisely controls the movement of each voice coil motor 22, drive motor 7, adjustment motor 24, and servo motor 13 (which is an actuator), thereby ensuring that the area scan camera 21 reaches the target position and ensuring that the visual inspection position of each product under inspection is consistent, thus improving the inspection accuracy.

[0039] S400: Glass plate 6 continues to move carrying the inspected products, and qualified and unqualified products are removed from glass plate 6 respectively.

[0040] S500: The glass plate 6 continues to move along the chain 4 until it reaches the flat suction nozzle 29. The vacuum cleaner, the main suction pipe 27 and the suction branch pipe 28 work together to suck away the debris and debris attached to the surface of the glass plate 6, so as to avoid the accumulation of debris and debris affecting the normal detection of the area array camera 21.

[0041] It is worth noting here that since the product is always placed on the outer surface of the glass plate 6, the outer surface of the glass plate 6 is the most prone to debris adhesion, while the inner surface is less contaminated because it does not directly contact the product and does not need to be cleaned frequently. Cleaning the outer surface of the glass plate 6 can ensure the best visual inspection effect of the area scan camera 21.

[0042] S600: The glass plate 6 continues to move along the chain 4 and passes through two wiper cloths 33. When it passes through the first wiper cloth 33, the sponge block 31 storing cleaning fluid delivers cleaning fluid to the wiper cloth 33 and cleans the surface of the glass plate 6. Then, when it passes through the second wiper cloth 33, the cleaning fluid on the surface of the glass plate 6 is wiped off by the dry wiper cloth 33 to ensure the transparency of the glass plate 6 and so that the area array camera 21 always maintains a good detection effect.

[0043] S700: Glass plate 6 continues to move along chain 4 and performs continuous inspection operations.

[0044] The multi-axis rotating area array visual inspection device provided by this invention uses a laser sensor as a feedback element to instruct the operation of each motor, causing the area array camera 21 to rotate or move in the X, Y, and Z axes, thereby realizing the multi-axis adjustment function of the area array camera 21. When inspecting products, the area array cameras 21, which are symmetrically arranged above and below the glass plate 6, are used to simultaneously perform visual inspection of the products through the glass plate 6. The inspection efficiency is high, there is no blind spot problem, and the inspection effect is good. In addition, with the flat suction nozzle 29 and two cloths 33 with sponge blocks 31, the residues attached to the surface of the glass plate 6 can be cleaned to ensure the transparency of the glass plate 6, thereby ensuring the visual inspection effect of the area array camera 21 and preventing misjudgment.
