Description

Technical Field

[0001] This invention relates to the field of bulb detection equipment technology, and in particular to an all-round automatic bulb detection equipment. Background Technology

[0002] Light-emitting diodes, also known as LEDs, are semiconductor components. LED lighting fixtures refer to devices that can transmit, distribute, and change the light distribution of LED light sources, including components required to fix and protect the LED light source, as well as wiring accessories required to connect to the power supply. Bulbs are a type of LED lighting fixture. Bulbs are a new type of energy-saving lamp that replaces traditional incandescent bulbs. Bulbs are characterized by energy saving and long lifespan. The main components of a bulb include a lampshade, a lamp holder, and a lamp base. During assembly, the lampshade is fixed to the lamp holder, and the lamp base is fixed directly below the lamp holder. The lamp base is connected to the driver power supply. Existing bulb lamp bases are mainly screw-type and plug-in type.

[0003] To ensure product quality after assembly, existing LED bulbs require inspection after production. This inspection includes aging tests, optical performance tests, and appearance defect detection. Currently, appearance defect detection is mostly done manually to check for scratches, damage, and insufficient fit between components. However, manual inspection leads to low production efficiency and difficulty in ensuring accuracy. While using existing vision inspection equipment can automate image acquisition and improve accuracy compared to manual inspection, the structural characteristics of LEDs still present challenges. Maintaining stable LED position during image acquisition and ensuring continuous sequential inspection of multiple LEDs (ensuring no displacement or drop during transport) remain issues. Furthermore, achieving omnidirectional image acquisition is crucial. Manual placement and adjustment are insufficient for automation.

[0004] Referring to Chinese invention patent publication number "CN103754640B" entitled "An LED Bulb Detection Device and Detection Method Thereof," the technical solution discloses "an LED bulb detection device and detection method thereof, the detection device including a bulb detection conveyor belt and a loading mechanism, a detection mechanism, and a unloading mechanism arranged sequentially, the bulb detection conveyor belt passing through the loading mechanism, the detection mechanism, and the unloading mechanism, the conveyor belt of the bulb aging line passing through the loading mechanism, and the conveyor belt of the bulb packaging line passing through the unloading mechanism." Although this detection device is used to detect loading, detection operation, and unloading to improve automation efficiency and achieve more efficient optical performance detection of bulbs, this technical solution cannot achieve automated all-round visual inspection of bulbs, and therefore cannot determine whether the appearance of the bulb has defects.

[0005] Therefore, how to automate the all-around visual inspection of bulbs is a technical problem that engineers need to solve. Summary of the Invention

[0047] Specifically, the surface of the rotating circular plate 1 is evenly provided with a plurality of mounting through holes, and the plurality of mounting through holes are aligned one-to-one with the plurality of first placement through holes 110. The plurality of mounting through holes are all used to allow the bulb lamp head of the first placement through hole 110 to extend out.

[0048] Specifically, a support base plate 13 is provided directly below the rotating circular plate 1. A drive mechanism 7 is provided on the support base plate 13. The drive mechanism 7 includes a rotating motor 71 and a reducer 72.

[0049] Specifically, when two feeding claws 223 are provided directly below the lifting plate 222, the two feeding claws 223 are respectively located at both ends of the lifting plate 222, and a straightening column 8 is provided below the supporting horizontal plate 21. The top of the straightening column 8 corresponds to the bottom of the lifting plate 222.

[0051] Specifically, a swing mechanism 9 is also provided below the other end of the mounting plate 41. The swing mechanism 9 includes an ejector cylinder 91 and a bearing plate 92.

The swing mechanism 9 is used to control the range of motion of the material discharge chute 43.

[0052] In Example 1, to achieve continuous automatic visual inspection of multiple bulbs, existing inspection equipment can only inspect a single bulb at a single station, which cannot achieve continuous inspection. Furthermore, due to the structural characteristics of the bulbs, it is difficult to keep their placement stable during the visual inspection process, resulting in tilting and offset during transportation. Therefore, it is difficult to achieve continuous automated visual inspection of multiple bulbs. To improve work efficiency, in this example, a rotating circular plate 1, a clamping and feeding device 2, a visual inspection component 3, and a clamping and unloading device 4 are provided.

[0053] By having several first material-carrying circular plates 11 arranged in a ring on the rotating circular plate 1, and second material-carrying circular plates 12 arranged between adjacent first material-carrying circular plates 11, by having a first placement through hole 110 opened inside the first material-carrying circular plate 11, and by having a second placement through hole 120 opened inside the second material-carrying circular plate 12, the clamping feeding device 2 and the clamping unloading device 4 are both located near the outside of the rotating circular plate 1. The first placement through hole 110 is adapted to the bulb lamp holder, and the second placement through hole 120 is adapted to the bulb lamp head. Therefore, the clamping feeding device 2 can be used to clamp and place the bulb to be tested into the first placement through hole 110, and the clamping unloading device 4 can be used to clamp the bulb in the second placement through hole 120.

[0054] The visual inspection component 3 includes an upper inspection camera 31 and a lower inspection camera 32. The camera of the upper inspection camera 31 faces the top of the rotating circular plate 1. When the rotating circular plate 1 aligns any of the second placement through holes 120 with the camera of the upper inspection camera 31, the upper inspection camera 31 can visually inspect the bulb holder and lampshade within the second placement through hole 120. The upper inspection camera 31 is positioned near the outside of the clamping and unloading device 4 to facilitate the clamping and unloading of the inspected bulbs, leaving the second placement through hole 120 empty. The camera of the lower inspection camera 32 faces the bottom of the rotating circular plate 1. Therefore, when the rotating circular plate... When any of the first placement through holes 110 is aligned with the camera of the lower detection camera 32, the lower detection camera 32 can perform visual inspection on the bulb head inside the first placement through hole 110. The lower detection camera 32 is located near the outside of the clamping and feeding device 2. The bulb to be inspected can be placed inside the first placement through hole 110 by the clamping and feeding device 2. When the first placement through hole 110 is aligned with the lower detection camera 32, the lower detection camera 32 can inspect the bulb head inside the first placement through hole 110. This effectively realizes the continuous automatic inspection of multiple bulbs and allows for comprehensive inspection of all components of the bulb during the inspection process.

[0055] It should be noted that, in order to ensure that the bulb head inside the first placement through hole 110 can be fully exposed at the bottom of the rotating circular plate 1 so that the lower detection camera 32 can capture images of the bulb head at the bottom of the rotating circular plate 1, a number of mounting through holes can be evenly opened on the surface of the rotating circular plate 1. The mounting through holes are aligned with the first placement through holes 110 one by one. Thus, the mounting through holes are all used to allow the bulb head inside the first placement through hole 110 to extend out. When a bulb is placed on the first loading circular plate 11, the mounting through holes facilitate the bulb head inside the first placement through hole 110 to extend out, so that the bulb head is fully exposed, so that the lower detection camera 32 can capture images of the bulb head.

[0056] It should be noted that, in order to achieve continuous sequential detection of multiple bulbs, the rotating disc 1 needs to be able to rotate circumferentially. In this embodiment, it should be further explained that a support base plate 13 is provided directly below the rotating disc 1, and a drive mechanism 7 is provided on the support base plate 13. The drive mechanism 7 includes a rotating motor 71 and a reducer 72. The power output end of the rotating motor 71 is connected to the reducer 72, and the power output end of the reducer 72 is fixedly connected to the center of the rotating disc 1. Therefore, the drive mechanism 7 can be used to drive the rotating disc 1 to rotate circumferentially. The rotating motor 71 drives the reducer 72, and the reducer 72 drives the rotating disc 1 to rotate circumferentially. The reducer 72 can prevent the rotation speed from being too high, which would affect the subsequent loading, unloading, and detection alignment. The reducer 72 plays the role of matching the speed and transmitting torque between the prime mover and the working machine or actuator.

[0057] It should be noted that, in order to automatically place the bulbs on the rotating circular plate 1, the clamping and feeding device 2 includes a supporting horizontal plate 21 and a sliding plate 22. One side of the sliding plate 22 is slidably mounted on one side of the supporting horizontal plate 21. A push cylinder 211 is also provided on one side of the supporting horizontal plate 21, and the power output end of the push cylinder 211 is fixedly connected to one end of the sliding plate 22. The other end of the sliding plate 22 is located directly above the rotating circular plate 1. A lifting cylinder 221 is also provided on the other side of the sliding plate 22, and a lifting plate 22 is provided on the power output end of the lifting cylinder 221. 22, and at least one feeding claw 223 is provided at the bottom of the lifting plate 222. The feeding claw 223 is used to clamp the bulb to be tested. During the feeding process, the power output end of the cylinder 211 can be pushed back to make the clamping surface of the feeding claw 223 completely aligned with the bulb to be tested and then stop. At this time, the power output end of the lifting cylinder 221 extends and drives the feeding claw 223 to move toward the bulb to be tested until the bulb to be tested is in the clamping surface of the feeding claw 223. The feeding claw 223 clamps and grabs the bulb to be tested. At this time, the power output end of the lifting cylinder 221 retracts to complete the material picking action.

[0058] After the material is picked up, when the bulb to be tested needs to be fed into the first placement through hole 110, the circular plate 1 can be rotated to align the empty first placement through hole 110 with the other end of the sliding plate 22. This pushes the power output end of the cylinder 211 to extend and moves the feeding claw 223 holding the bulb to be tested onto the empty first placement through hole 110. At this time, the power output end of the lifting cylinder 221 extends again, bringing the feeding claw 223 holding the bulb closer to the first placement through hole 110 until the bulb to be tested is inside the first placement through hole 110, thus completing the automatic feeding action, realizing automated feeding and improving work efficiency.

[0059] It should be noted that, since the first placement through hole 110 is adapted to the bulb lamp holder, the bulb lamp head inside the first placement through hole 110 will be completely exposed at the bottom of the rotating circular plate 1.

[0060] In conjunction with the above description of the feeding action in the clamping and feeding device 2, it should be further explained that, in order to achieve the alignment action of the bulb before feeding, since the bulb may tilt during material handling, an alignment action is required. Furthermore, to achieve synchronous operation of the two workstations and improve work efficiency, in this embodiment: two feeding grippers 223 can be provided, with the two feeding grippers 223 respectively located at both ends of the lifting plate 222. An alignment column 8 is provided below the supporting horizontal plate 21, with the top of the alignment column 8 corresponding to the bottom of the lifting plate 222. An alignment through hole 81 for inserting the bulb lamp head is provided at the top of the alignment column 8. Additionally, the two feeding grippers 223... A limiting device 224 is provided between the grippers, and the side of the limiting device 224 facing the alignment through hole 81 is provided with an arc-shaped groove 225. It can be moved synchronously by two feeding grippers 223. When one feeding gripper 223 is directly above the rotating circular plate 1, the other feeding gripper 223 can be aligned with the alignment through hole 81, which facilitates the synchronous placement of the bulb to be tested in the rotating circular plate 1 / alignment through hole 81. One feeding gripper 223 can grasp the bulb in the alignment through hole 81, and the other feeding gripper 223 can grasp the bulb to be tested and place it in the alignment through hole 81 to perform the alignment action. This effectively realizes the synchronous feeding action of dual stations and improves work efficiency.

[0061] During the alignment process, that is, before the bulb to be tested is clamped and fed into the first placement through hole 110 of the rotating circular plate 1, the upper and lower limits of the bulb can be achieved by the alignment through hole 81 and the limiting kit 224 to ensure that the position of the bulb will not be tilted. This effectively ensures that when the bulb is subsequently fed into the rotating circular plate 1, it can be placed vertically in the first placement through hole 110, effectively preventing the bulb from tilting on the rotating circular plate 1 and improving the accuracy of subsequent detection.

[0062] It should also be noted that the limiting kit 224 can be movably positioned between the two gripping fingers of the loading gripper 223 by means of an elastic element, so as to provide a certain amount of movement space for the limiting kit 224 by means of an elastic element, so as to prevent the limiting kit 224 from directly colliding with the bulb and causing damage when the loading gripper 223 is loading or unloading materials.

[0063] It should be noted that each of the two gripping fingers of the feeding claw 223 can be equipped with a set of rotating wheels, so that the set of rotating wheels is tangent to the outside of the bulb. This is to prevent damage to the surface of the bulb when gripping it, and to facilitate the placement of the bulb in the alignment position, by providing the bulb with room to move through the set of rotating wheels.

[0064] It should be noted that the clamping and unloading device 4 includes a mounting plate 41 and a movable plate 42. One end of the mounting plate 41 is positioned above the rotating circular plate 1. A telescopic cylinder 411 is provided at one end of the mounting plate 41, and a unloading chute 43 is movably provided below the other end of the mounting plate 41. One side of the movable plate 42 is slidably mounted on the mounting plate 41, and the power output end of the telescopic cylinder 411 is fixedly connected to the outside of the movable plate 42. Therefore, the telescopic cylinder 411 can be used to control the moving distance of the movable plate 42. At least one pressing cylinder 421 is provided on the other side of the movable plate 42, and a unloading gripper 422 is provided on the power output end of the pressing cylinder 421. Both gripping fingers of the unloading gripper 422 are arranged in an arc shape. The telescopic cylinder 411 controls the moving distance of the movable plate 42 on the mounting plate 41. When the power output end of the telescopic cylinder 411 extends / retracts, it can drive... The moving horizontal plate 42 moves away from / closes to the rotating circular plate 1. Before material is to be dropped, the moving horizontal plate 42 needs to be positioned directly above the rotating circular plate 1. The power output end of the pressing cylinder 421 extends, thereby driving the dropping claw 422 to approach the second placement through hole 120, so that the dropping claw 422 can be aligned with the second placement through hole 120 on the rotating circular plate 1. After clamping and picking up the bulbs that have been inspected in the second placement through hole 120, the power output end of the pressing cylinder 421 resets, completing the process. The removal action is completed when the bulb that has been tested in the second placement through hole 120 is removed. Then, the telescopic cylinder 411 drives the moving horizontal plate 42 to move again, so that the dropping claw 422 holding the bulb moves to the top of the dropping chute 43. Then, the pressing cylinder 421 drives the dropping claw 422 to approach the dropping chute 43 until the bottom of the bulb contacts the end of the dropping chute 43. Then, the bulb is released, so that the bulb can slide down through the dropping chute 43, completing the dropping action.

[0065] In Example 2, to automate the visual inspection of the bulb lamp holder, to ensure the bulb is placed stably, the bulb lamp holder will be located inside the first placement through hole 110, thus obstructing the position of the bulb lamp holder and part of the lamp cover. Therefore, to achieve image acquisition of all components of the bulb, the bulb needs to be moved from the first placement through hole 110 to the second placement through hole 120, so that comprehensive image acquisition and visual inspection of the bulb lamp holder and lamp cover can be performed, ensuring that all components of the bulb can be visually inspected. In this example, a material transfer device 6 is also provided outside the rotating circular plate 1 to transfer... The transfer device 6 is located between the upper inspection camera 31 and the lower inspection camera 32. It can be used to clamp and move the bulb in the first placement through hole 110 to the second placement through hole 120. After the lower inspection camera 32 has completed the inspection of the bulb lamp head in the first placement through hole 110, it moves the bulb in the first placement through hole 110 to the second placement through hole 120, so that the bulb lamp holder and lamp cover in the second placement through hole 120 are exposed. This makes it easier for the upper inspection camera 31 to collect images of the bulb lamp holder and lamp cover, so as to achieve the effect of comprehensive visual inspection of all components of the bulb.

[0066] It should be noted that the material transfer device 6 includes a fixed plate 61 and a displacement cylinder 62. The displacement cylinder 62 is fixed to one side of the fixed plate 61. A lifting module 63 is slidably mounted on one side of the fixed plate 61, so that the power output end of the displacement cylinder 62 is fixedly connected to the outside of the lifting module 63. A movable plate 631 is also mounted on the sliding block of the lifting module 63, with one end of the movable plate 631 located at the top of the rotating circular plate 1. A material transfer gripper 632 is mounted on one end of the movable plate 631, with the gripping surface of the gripper 632 facing the rotating circular plate 1. The two gripping fingers of the gripper 632 are arranged in an arc shape. Therefore, the lifting module 63 can be driven by the displacement cylinder 62 to slide on the fixed plate 61. The lifting module 63 can also be used to control the movable plate 63. When material needs to be moved, the lifting height of the moving plate 631 can be adjusted by the displacement cylinder 62 to drive the lifting module 63, so that the material transfer gripper 632 can be aligned with the position of the first placement through hole 110. The lifting module 63 then drives the material transfer gripper 632 to approach the bulb in the first placement through hole 110. After the material transfer gripper 632 clamps the bulb in the first placement through hole 110, the lifting module 63 resets, completing the removal of the bulb from the first placement through hole 110. The displacement cylinder 62 then drives the lifting module 63 to move on the fixed plate 61 again, so that the material transfer gripper 632 holding the bulb can be aligned with the second placement through hole 120. The lifting module 63 then descends again. During this process, the bulb's lamp head cooperates with the second placement through hole 120, and the material transfer gripper 632 releases, completing the automatic material transfer action, which facilitates all-round inspection of the bulb's components.

[0067] In this embodiment, it should be further described that during material transfer, the bulb in the first placement through hole 110 can be moved to the second placement through hole 120. Since the first placement through hole 110 is adapted to the bulb holder and the second placement through hole 120 is adapted to the bulb head, when the bulb is in the first placement through hole 110, the bulb head will be completely exposed at the bottom of the first placement through hole 110, and when the bulb is in the second placement through hole 120, the bulb holder and lampshade will be completely exposed at the top of the second placement through hole 120, so as to facilitate visual inspection of the various components of the bulb.

[0068] In Example 3, combining the technical solutions in the above examples, to achieve automated position adjustment of the bulb, since the visual inspection process requires image acquisition of the bulb's shape, and the image acquisition camera is mostly fixedly installed, only partial images can be acquired during the image acquisition process, making it difficult to acquire omnidirectional images of all parts of the bulb. Therefore, it is necessary to ensure that the acquisition camera can acquire images of all parts of the bulb from all directions. In this example: a rotating circular plate 1 and a visual inspection component 3 are provided. The visual inspection component 3 includes an upper inspection camera 31 and a lower inspection camera 32. The camera of the upper inspection camera 31 faces the top of the rotating circular plate 1, and the camera of the lower inspection camera 32 faces the bottom of the rotating circular plate 1. Several first material-carrying circular plates 11 are arranged in a ring on the rotating circular plate 1, and a second material-carrying circular plate is provided between adjacent first material-carrying circular plates 11. The material-carrying circular plate 12 is rotatably mounted on the rotating circular plate 1, with two adjustment devices 5 arranged outside the rotating circular plate 1. One adjustment device 5 is located near the outside of the upper detection camera 31, and the other adjustment device 5 is located near the outside of the lower detection camera 32. The adjustment device 5 includes a servo motor 51 and a drive gear 52. The drive gear 52 is fixed to the power output end of the servo motor 51, so that the outer walls of the first material-carrying circular plate 11 and the second material-carrying circular plate 12 are meshed with the drive gear 52. When the lower detection camera 32 is acquiring images of the bulb lamp head, one of the adjustment devices 5 can drive the first material-carrying circular plate 11 to rotate in a circle, thereby driving the bulb on the first material-carrying circular plate 11 to rotate in a circle, so that the lower detection camera 32 can acquire images of the bulb lamp head in a comprehensive manner.

[0069] When the upper inspection camera 31 acquires images of the bulb cover and lamp holder, another adjustment device 5 can drive the second material carrier plate 12 to rotate circumferentially, thereby driving the bulb on the second material carrier plate 12 to rotate circumferentially. This allows the upper inspection camera 31 to acquire comprehensive images of the bulb cover and lamp holder, effectively achieving comprehensive image acquisition of all components of the bulb, and realizing the effect of visual inspection of all components of the bulb from all directions.

[0070] In embodiment four, to automate the unloading of the bulbs within the second placement through-hole 120, the following is implemented: a rotating circular plate 1 and a clamping unloading device 4 are provided. The clamping unloading device 4 is positioned near the outside of the rotating circular plate 1. The clamping unloading device 4 includes a mounting horizontal plate 41 and a movable horizontal plate 42. One end of the mounting horizontal plate 41 is positioned above the rotating circular plate 1. A telescopic cylinder 411 is provided at one end of the mounting horizontal plate 41, and a unloading chute 43 is movably provided below the other end of the mounting horizontal plate 41. One side of the movable horizontal plate 42 is slidably mounted on the mounting horizontal plate 41, so that the power output end of the telescopic cylinder 411 is fixedly connected to the outside of the movable horizontal plate 42. Therefore, the telescopic cylinder 411 can be used to control the moving distance of the movable horizontal plate 42. At least one pressing cylinder 421 is also provided on the other side of the movable horizontal plate 42, and a material dropping claw 422 is provided on the power output end of the pressing cylinder 421. The two gripping fingers of the material dropping claw 422 are both arranged in an arc shape. The telescopic cylinder 411 controls the movement of the movable horizontal plate 42. The moving distance on the mounting plate 41 allows the moving plate 42 to move away from / close to the rotating circular plate 1 when the power output end of the telescopic cylinder 411 extends / retracts. Before material is dropped, the moving plate 42 needs to be positioned directly above the rotating circular plate 1. The power output end of the pressing cylinder 421 extends, thereby driving the dropping gripper 422 closer to the second placement through hole 120, so that the dropping gripper 422 can be aligned with the second placement through hole 120 on the rotating circular plate 1. After clamping and picking up the bulbs that have been tested in the second placement through hole 120, the material is removed. The power output end of the pressing cylinder 421 is reset, completing the removal action. After the bulb that has been tested in the second placement through hole 120 is removed, the telescopic cylinder 411 drives the moving horizontal plate 42 to move again, so that the dropping claw 422 holding the bulb moves to the top of the dropping chute 43. The pressing cylinder 421 drives the dropping claw 422 to approach the dropping chute 43 again until the bottom of the bulb contacts the end of the dropping chute 43 and then releases the bulb, allowing the bulb to slide down through the dropping chute 43, completing the dropping action.

[0071] To further improve upon the above description, in order to achieve the marking action on the bulbs before the automatic feeding action, and to ensure the traceability of each bulb during continuous batch production, it is necessary to mark each bulb for traceability. Two pressing cylinders 421 can be provided, positioned at opposite ends of the moving horizontal plate 42. A marking mechanism is also provided directly below the clamping and feeding device 4, positioned between the rotating circular plate 1 and the feeding chute 43. The inlet of the marking mechanism faces the bottom of the moving horizontal plate 42, and the marking mechanism marks the bulbs. The operation is designed to facilitate subsequent classification and tracing of the bubbles. Furthermore, to achieve synchronous operation at two stations and improve work efficiency, when one pressing cylinder 421 is above the rotating disc 1, the other pressing cylinder 421 is above the marking mechanism. While the dropping jaws 422 on one pressing cylinder 421 move the bubbles from the rotating disc 1 to the inlet of the marking mechanism, the dropping jaws 422 on the other pressing cylinder 421 move the bubbles from the marking mechanism to the dropping chute 43. The two dropping jaws 422 simultaneously clamp the bubbles, and this synchronous operation at two stations effectively improves work efficiency.

[0072] To further supplement the above explanation, in order to achieve the sorting and unsorting of qualified and unqualified products, a swing mechanism 9 is also provided below the other end of the mounting plate 41. The swing mechanism 9 includes an ejector cylinder 91 and a supporting plate 92. The ejector cylinder 91 is fixed on the supporting plate 92, so that the bottom of the unloading chute 43 is rotatably mounted on the supporting plate 92. The power output end of the ejector cylinder 91 is also hinged to the bottom of the unloading chute 43. When it is necessary to adjust the unloading chute 43, it can be adjusted by the swing mechanism. The mechanism 9 controls the rotation direction of the unloading chute 43 and adjusts the outlet of the unloading chute 43 to face the qualified / unqualified product bin, so as to realize the centralized unloading of qualified / unqualified products. During operation, the power output end of the ejector cylinder 91 can be extended to drive the unloading chute 43 to rotate on the support plate 92, so that the outlet of the unloading chute 43 faces the qualified / unqualified product bin. After the power output end of the ejector cylinder 91 retracts, the unloading chute 43 is reset on the support plate 92.

[0073] Combining the technical solutions in the above embodiments, the position of the bulb can be automatically adjusted to achieve comprehensive image acquisition of all components of the bulb. During the acquisition process, the bulb can be placed stably. Furthermore, combined with AI visual inspection methods, it can determine whether the product's appearance has defects. Through a clamping and unloading device, product sorting and unloading are achieved. This invention effectively realizes automated comprehensive visual inspection of the bulb, improving work efficiency and inspection accuracy. AI visual inspection is a detection method that combines artificial intelligence technology and machine vision technology. It acquires images through machine vision and automatically identifies and analyzes the images through a combination of deep learning and computer vision algorithms. Using this detection method, it can automatically determine whether a product has defects. Compared with manual visual inspection, this detection method has high automation and high accuracy.
