Description
Technical Field
[0001] The present invention relates to the technical field of visual detection, and in particular to an automatic detection device based on visual sensing. Background Art
[0002] In modern manufacturing, product quality inspection is a key link to ensure that products meet standards and customer needs. With the continuous expansion of production scale and the increase in product complexity, the requirements for inspection efficiency and accuracy are also increasing. Traditional manual inspection methods are difficult to meet the needs of large-scale, high-precision inspections. Not only are the inspection speeds slow and inefficient, but they are also easily affected by human factors, such as fatigue and subjective judgment errors, which makes it difficult to ensure the accuracy and reliability of the inspection results. Therefore, visual sensing inspection devices are needed for inspection.
[0003] Visual sensing is a technical means of obtaining information about target objects using optical imaging devices (such as cameras) and image processing technology. By collecting, transmitting, processing and analyzing the images of objects, visual sensors can extract various features of objects, including shape, size, color, texture, position, posture, etc., and then realize the functions of object recognition, detection, measurement, positioning and tracking.
[0004] Existing visual sensing detection devices use electric push rods for preliminary positioning in terms of object posture correction. They lack accurate perception and intelligent control capabilities and are difficult to adapt to objects of different shapes, sizes and complex postures, resulting in large posture deviations when objects enter the detection area, seriously affecting the accuracy and reliability of subsequent detection. The degree of automation in the defective product processing link is not high, and manual intervention is often required for sorting and recording. This is not only inefficient, but also easy to cause defective products to mix with good products due to human operational errors. In addition, the information exchange between the detection data and the production system is not timely and comprehensive enough, and it is impossible to quickly feedback and adjust problems in the production process, making it difficult to achieve efficient automation and intelligent control of the entire production inspection process.

[0018] The present invention provides an automatic detection device based on visual sensing, which has the following beneficial effects:
[0019] 1. The present invention uses a correction mechanism that cooperates with a laser sensor, an electric telescopic rod, and a correction roller to accurately correct the posture of the product, ensure that the product enters the detection area in a standard state, reduce the detection error caused by position and posture deviation, and improve detection accuracy. Secondly, the visual inspection link relies on advanced algorithms and standard models to analyze images, which can comprehensively check the various characteristics of the product and accurately judge its quality. Finally, the defective product processing mechanism can respond quickly, the manipulator can accurately grab the defective products, and the sound and light alarm can remind in time, which not only ensures that the defective products are properly handled, but also facilitates the operator to monitor and adjust the production process in time, effectively improve the overall production inspection efficiency, stabilize product quality, and help the production process to be carried out efficiently and orderly.
[0020] 2. The operation of the exhaust fan of the present invention causes the outside air to enter the dehumidification box through the air inlet, and the moisture absorbing component first absorbs moisture from the air, effectively reducing the humidity of the air. This ensures that the inherent quality of the product is fully maintained during the test, significantly improving the accuracy and reliability of the test data. The air then passes through the connecting hole and enters the meandering guide plate area, further optimizing the dryness and flow direction of the air, making the humidity distribution in the test area more uniform, and reducing the interference of local humidity differences on the test results. This is not only conducive to accurately judging product quality, but also reduces the risk of failure of testing equipment due to humidity problems, extends the service life of the equipment, and reduces maintenance costs and downtime. It creates a stable and suitable environment for automated testing, greatly improving the efficiency and quality of testing.
[0021] 3. The present invention adjusts the position of the moving plate and the conveyor belt by turning the handle, allowing only a single product to pass through. A single product allows the visual sensor to collect a clear, complete image that is not interfered with by other products, making it easier for the visual computer to accurately determine whether it is a defective product. When the product is transported to the bottom of the dust hood, the vacuum cleaner sucks away dust and impurities, greatly reducing the interference of dust on visual detection. This makes the image collected by the visual sensor clearer and more accurate, improves the reliability of the detection results, and reduces the risk of misjudgment caused by factors such as dust obstruction.

DETAILED DESCRIPTION
[0036] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] See also Figure 1-Figure 11The embodiment of the present invention provides an automated detection device based on visual sensing, including a support leg 1, a visual sensor 6, a defective product processing mechanism 9 and a visual computer 11. The support leg 1 provides a stable and reliable support foundation for the entire automated detection device. The visual sensor 6 can collect image information of the product with high precision, and through advanced optical technology and image capture capabilities, quickly obtain the contour, texture, color and other rich details of the product, providing a key data source for the subsequent visual computer 11 to make accurate quality judgments according to preset standards, greatly improving the accuracy and efficiency of detection. It is composed of a manipulator 902 and a defective product box 903. When the visual computer determines that the product is defective, the manipulator 902 quickly and accurately grabs the defective product under the precise control of the visual computer 11 and places it in the defective product box 903. The visual computer 11 is the intelligent control and data processing core of the entire detection device. It can not only receive and process the image data transmitted by the visual sensor 6, use complex image analysis algorithms and image feature data models of standard products for in-depth comparison and judgment, but also control the extension and retraction of the electric telescopic rod 702 according to the data of the laser sensor 705 of the correction mechanism 7, so as to realize the intelligent regulation of the correction mechanism 7. At the same time, it works in coordination with the defective product processing mechanism 9, the sound and light alarm 12, etc., to realize the efficient integration and precise control of the automated detection process, greatly reducing the errors and uncertainties caused by manual intervention, and improving the accuracy, reliability and automation of the production detection process. A transport mechanism 2 is arranged on the top of the multiple support legs 1, which smoothly and continuously transports the product from the initial loading position to each detection and processing link, ensuring the efficiency and continuity of product transmission. The outside of the transport mechanism 2 is fixedly connected with two connecting plates 13, which are key components for connecting the transport mechanism 2 with other multiple mechanisms, and provide a stable installation platform for the loading mechanism 3, the dust collection mechanism 4, the correction mechanism 7 and the dehumidification mechanism 8. A feeding mechanism 3 is provided on the top of the connecting plate 13, which allows only a single product to pass through and be smoothly placed on the conveyor belt 206 at a time. A dust collection mechanism 4 is provided on the top of the connecting plate 13 to prevent dust from adhering to the surface of the product and affecting the accurate judgment of the quality characteristics of the product itself, reduce misjudgment and missed detection caused by dust factors, and improve the reliability and authenticity of the detection results. A correction mechanism 7 is provided on the outside of the connecting plate 13. The laser sensor 705 first performs preliminary sensing of the position and posture of the product, and transmits the data to the visual computer 11. The visual computer 11 controls the extension and retraction of the electric telescopic rod 702 based on this, and drives the correction roller 704 to move. Two dehumidification mechanisms 8 are provided between the two connecting plates 13 to ensure that the inherent quality of the product is completely maintained during the detection period, which significantly improves the accuracy and reliability of the detection data. The visual sensor 6 is connected to the visual computer 11, and closely cooperates with the visual computer 11 and the visual sensor 6 to achieve seamless connection between the detection and processing links.The visual sensor 6 is responsible for collecting product images, the visual computer 11 performs analysis and judgment and issues instructions to the robot 902, the robot 902 performs the grasping action and puts the defective products into the defective product box 903, the information transmission between each link is fast and accurate, and the actions are coordinated and smooth.
[0038] The defective product handling mechanism 9 includes a manipulator 902 and a defective product box 903. The manipulator 902 is connected to the visual computer 11, so that after the visual computer 11 analyzes and determines the defective products through the image data collected by the visual sensor 6, it can quickly and accurately command the manipulator 902 to move. One side of the defective product box 903 is fixedly connected to the outer side of one of the connecting plates 13, providing a special storage container for the defective products grabbed by the manipulator 902.
[0039] The correction mechanism 7 includes two electric telescopic rods 702, and the visual computer 11 is connected to the electric telescopic rods 702. The two electric telescopic rods 702 can perform independent and coordinated position adjustment actions from both sides of the product, respectively, providing multi-dimensional correction power. The connection of the visual computer 11 realizes intelligent control, and can command the electric telescopic rods 702 to extend to the appropriate length in real time based on accurate algorithms and detection data, and accurately adjust the product posture. Compared with manual adjustment, it greatly improves the accuracy and speed of correction, and reduces the correction deviation caused by human misjudgment or imprecise operation. The electric telescopic rod 702 is arranged on one side of the connecting plate 13, and the telescopic ends of the two electric telescopic rods 702 are arranged oppositely. The layout installed on one side of the connecting plate 13 makes the entire correction mechanism 7 compact and stable, does not occupy too much extra space, and is convenient for reasonable layout and integration in the automated detection device. The relatively arranged telescopic ends can form a stable clamping and correction force application point for the product located in the middle position, ensuring that the product is evenly and balanced during the correction process. The telescopic end of the electric telescopic rod 702 is fixedly connected to a connection frame 703, and the inner wall of the connection frame 703 is rotatably connected to multiple correction rollers 704. The connection frame 703 acts as a carrier of the correction rollers 704. As the electric telescopic rod 702 is extended and retracted, it moves and drives the correction rollers 704 to perform contact correction on the product. The correction rollers 704 can form rolling friction with the surface of the product instead of sliding friction. While effectively correcting the position and posture of the product, it greatly reduces scratches, wear and other damages to the surface of the product. Laser sensors 705 are set on the opposite sides of the two connection frames 703. The laser sensors 705 are connected to the visual technology machine 11. The laser sensors 705 can quickly and accurately obtain the position and posture information of the product. Through the connection with the visual computer 11, the real-time sensing data is transmitted to the visual computer 11. The visual computer 11 uses these data for analysis and decision-making, determines the movement amplitude and direction of the electric telescopic rod 702, and realizes closed-loop control of the correction process.
[0040] See also Figure 1The bottom of the manipulator 902 is fixedly connected to a support plate 901 , and one side of the support plate 901 is fixedly connected to the outer side of one of the connecting plates 13 . The support plate 901 constructs a solid infrastructure for the manipulator 902 .
[0041] See also Figure 1 , Figure 2 and Figure 8 The outer side of the electric telescopic rod 702 is fixedly connected with a fixing plate 701 , one side of the fixing plate 701 is fixedly connected to the outer side of the connecting plate 13 , and the fixing plate 701 firmly anchors the electric telescopic rod 702 on the connecting plate 13 .
[0042] See also Figure 1-Figure 2 A workbench 10 is arranged on the outside of the supporting leg 1, and the top of the workbench 10 is connected to the visual computer 11. The visual computer 11 is arranged on the workbench 10 outside the supporting leg 1, which provides a stable and dedicated placement area for the visual computer 11. An audible and visual alarm 12 is connected to one side of the top of the workbench 10, and the audible and visual alarm 12 is connected to the visual computer 11. When the visual computer 11 detects defective products or other abnormal conditions through image analysis, it will immediately send instructions to the audible and visual alarm 12 to make it emit audible and visual signals. This intuitive and strong warning can quickly attract the attention of on-site operators. Even in a noisy production environment or when the operator is far away from the device, problems that occur during the detection process can be known in time, so that corresponding measures can be taken at the first time. The audible and visual alarm 12 serves as an important information exchange medium between the visual computer 11 and the operator, strengthening the connection and collaboration between man and machine.
[0043] See also Figure 1-Figure 4 The transport mechanism 2 includes two mounting plates 201. The bottom of the mounting plates 201 is fixedly connected to the top of the support leg 1. The connection between the mounting plates 201 and the support leg 1 builds a solid foundation for the entire transport mechanism 2. The mounting plates 201 are rotatably connected with an active roller 203 and a driven roller 204. The active roller 203 and the driven roller 204 are sleeved with a conveyor belt 206. The active roller 203 and the driven roller 204 rotate to cooperate with the conveyor belt 206, thereby achieving continuous and smooth transportation of the product. The active roller 203 rotates under power drive, driving the conveyor belt 206 to move, and the driven roller 204 plays the role of auxiliary support and guidance, ensuring that the conveyor belt 206 maintains appropriate tension and running track.
[0044] See also Figure 3-Figure 4The inner wall of the conveyor belt 206 is sleeved with a plurality of conveyor rollers 205, and the ends of the conveyor rollers 205 are rotatably connected to the outer side of the mounting plate 201. The conveyor rollers 205 are arranged between the two mounting plates 201, and can play a multi-point support role for the conveyor belt 206. When the product is placed on the conveyor belt 206, even if the weight of the product is unevenly distributed or heavy, the conveyor rollers 205 can effectively share the pressure borne by the conveyor belt 206. A motor 202 is fixedly connected to the outer side of one of the mounting plates 201, and the output end of the motor 202 is fixedly connected to one end of the active roller 203. The motor 202, as a power source, provides a stable and continuous driving force for the entire transport mechanism 2. By fixing its output end to the active roller 203, the rotational motion of the motor 202 can be efficiently transmitted to the active roller 203, thereby driving the conveyor belt 206 and the driven roller 204 to rotate, so that the product can be stably transported in the set direction and speed.
[0045] See also Figure 1-Figure 2 The feeding mechanism 3 includes a mounting frame 301 and a connection plate 306. The mounting frame 301 and the connection plate 306 are important components of the feeding mechanism 3 and together build the basic framework of the entire feeding operation. The bottom of the mounting frame 301 is fixedly connected to the top of the connecting plate 13. The mounting frame 301 can rely on the stability of the connecting plate 13 to ensure that its position in the entire device is stable and reliable. The outer side of the mounting frame 301 is fixedly connected to the movable plate 303 by bolts 304, and the rotating end of the bolt 304 is fixedly connected to the rotating handle 305. The movable plate 303 is fixed by the combination of the bolt 304 and the rotating handle 305. The operator can easily operate the bolt 304 by rotating the handle 305, thereby realizing the up and down movement adjustment of the movable plate 303 on the mounting frame 301. According to the actual size and shape of the product, the gap between the movable plate 303 and the conveyor belt 206 can be flexibly changed, and the width of the feeding channel can be accurately controlled to ensure that only one product can pass through and enter the conveyor belt 206 at a time. The outer side of the connecting plate 306 is fixedly connected to the end of the mounting plate 201, and the top of the connecting plate 306 is fixedly connected with a baffle 302, so that the product can smoothly transition from the connecting plate 306 to the conveyor belt 206. The baffle 302 is fixed on the top of the connecting plate 306, which can block and position the placed products. When the product is placed on the conveyor belt 206, the baffle 302 can limit the position of the product to prevent it from excessively deflecting or sliding during the initial placement stage, ensuring that the product accurately falls on the predetermined loading position, thereby ensuring that the product can subsequently enter each inspection link along the conveyor belt 206 accurately.
[0046] See also Figure 1 , Figure 2 and Figure 6The dust collecting mechanism 4 includes a support frame 401, the bottom of which is fixedly connected to the top of the connecting plate 13. The support frame 401 serves as the basic support part of the dust collecting mechanism 4. Through the fixed connection with the top of the connecting plate 13, a stable structure is built for the entire dust collecting mechanism 4. A dust collecting hood 402 is fixedly connected to the inner side of the support frame 401. The top of the dust collecting hood 402 is connected to a dust collecting pipe 403. The dust collecting pipe 403 is connected to an external vacuum cleaner. The dust collecting pipe 403 serves as a channel connecting the dust collecting hood 402 and the external vacuum cleaner, and can effectively transfer the suction force generated by the vacuum cleaner to the area where the dust collecting hood 402 is located, so that a negative pressure environment is formed in the dust collecting hood 402, thereby strongly sucking away dust, debris and other impurities on the surface of the product. The smooth transmission of suction force is guaranteed, the dust collecting ability of the vacuum cleaner is fully utilized, and a more thorough cleaning of the product surface is achieved, so as to avoid dust from affecting the normal operation of the visual sensor 6 and other equipment and the accuracy of product quality judgment in the subsequent detection link, thereby improving the reliability of the entire detection process.
[0047] See also Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11The dehumidification mechanism 8 includes a fixing rod 801, the tops of the four fixing rods 801 are fixedly connected to the bottom of the connecting plate 13, and a dehumidification box 802 is fixedly connected between the four fixing rods 801. The fixing rods 801 firmly connect the dehumidification box 802 to the bottom of the connecting plate 13, providing a stable support structure for the dehumidification box 802, and the dehumidification box 802 provides an installation position for the internal partition 807, the exhaust fan 805, etc. A plurality of air inlet holes 803 are provided on both sides of the top of the dehumidification box 802, and two partitions 807 are fixedly connected to the inner wall of the dehumidification box 802. An exhaust fan 805 is fixedly connected between the partition 807 and the inner wall of the dehumidification box 802 through a connecting rod 804. The partition 807 separates a specific space inside the dehumidification box 802, and together with the inner wall of the dehumidification box 802, forms a channel for air flow, and the exhaust fan 805 is installed in this channel and fixed by the connecting rod 804. When the exhaust fan 805 is working, it can guide the air to flow between the partition 807 and the box wall along a predetermined path, so that the air can be fully dehumidified by the subsequent moisture absorbing member 806, and avoid the chaotic air flow causing some humid air to be discharged without effective dehumidification. The moisture absorbing member 806 is fixedly connected between the partition 807 and the inner wall of the dehumidification box 802. The moisture absorbing member 806 is fixed in the space between the partition 807 and the box wall. When the air flows through here under the action of the exhaust fan 805, the moisture absorbing member 806 can fully absorb the moisture in the air and reduce the air humidity. The moisture absorbing member 806 can be made of high-efficiency moisture absorbing materials, such as silica gel, molecular sieve, etc., which have a large moisture absorption capacity and a fast moisture absorption speed, and can quickly capture moisture during the short stay time of the air, thereby ensuring that the air humidity discharged from the dehumidification box 802 reaches a low level. A connecting hole 808 is provided on the inner wall of the partition 807, and a circular guide plate 809 is fixedly connected between the two partitions 807. Multiple air outlet holes 8010 are provided on both sides of the outside of the dehumidification box 802. After the air is initially dehumidified by the moisture absorbing member 806, it enters the area between the two partitions 807 through the connecting hole 808. The presence of the circular guide plate 809 prolongs the residence time of the air in this area, allowing the air to further remove residual moisture and be evenly discharged from the air outlet holes 8010.
[0048] See also Figure 1-Figure 2 The top of the connecting plate 13 is fixedly connected with the visual detection bracket 5, and the connecting plate 13 provides a solid and reliable installation foundation for the visual detection bracket 5. The bottom of the visual detection bracket 5 is connected to the visual sensor 6. The visual detection bracket 5 serves as a bearing platform for the visual sensor 6. Its reasonable structural design and stable connection method can ensure that the visual sensor 6 is correctly installed and in the best working state.
[0049] Working principle: First, by turning the rotating handle 305 to operate the bolt 304, the movable plate 303 is moved up and down on the mounting frame 301 to adjust the position with the conveyor belt 206, so that only one product can pass. After the position is adjusted, the rotating handle 305 is turned to make the bolt 304 fix the movable plate 303 on the mounting frame 301, and then the motor 202 is started. The motor 202 drives the active roller 203 to rotate, and the active roller 203 drives the conveyor belt 206 and the driven roller 204 to operate. The conveyor roller 205 assists in supporting the conveyor belt 206, so that the product moves to the detection area with the conveyor belt 206. At this time, the product is placed between the baffle 302 and the movable plate 303, and placed on the conveyor belt 206. The conveyor belt 206 drives the product to move to the detection area. When it moves to the bottom of the dust hood 402, the vacuum cleaner generates suction on the dust hood 402 through the dust suction pipe 403, and sucks away impurities such as dust on the product to prevent dust from affecting the accuracy of visual inspection and subsequent processing.
[0050] When the product reaches the position of the correction mechanism 7 during transportation, the laser sensors 705 on the opposite sides of the two connection frames 703 of the correction mechanism 7 first perform preliminary position and posture sensing of the product and transmit the data to the visual computer 11. The visual computer 11 controls the extension and retraction of the electric telescopic rod 702 according to the received data of the laser sensor 705 and the preset standard position and posture parameters. Its telescopic end drives the connection frame 703 and the correction roller 704 connected to the internal rotation to move. When the correction roller 704 contacts the product, it uses its rotation characteristics to accurately correct the position and posture of the product without damaging the product, ensuring that the product enters the subsequent detection area with the correct position and posture.
[0051] The corrected product continues to move forward along the conveyor belt 206. When it reaches the bottom of the visual inspection bracket 5, the visual sensor 6 collects images of the product and quickly transmits the collected image data to the visual computer 11. The visual computer 11 uses a pre-set image analysis algorithm and an image feature data model of a standard product to perform detailed analysis and processing on the image transmitted by the visual sensor 6. For example, by comparing the differences between the contour, texture, color and other features of the product in the image and the standard features, it can be determined whether the product has surface defects, whether the size meets the standard requirements and other inspection items.
[0052] If the visual computer 11 determines that the product is defective after image analysis, it will immediately send instructions to the defective product processing mechanism 9. Under the precise control of the visual computer 11, the manipulator 902 grabs the defective product from the conveyor belt 206 through the stable support provided by the support plate 901, and places it in the defective product box 903. At the same time, the visual computer 11 will also control the sound and light alarm 12 to send out an alarm signal to remind the on-site operator that defective products have been produced, so that the operator can monitor and adjust the production process in time, such as checking whether the production equipment has malfunctions, whether there are problems with the raw materials, etc., so as to ensure the efficiency of the entire production inspection process and the stability of product quality. The products that have been tested as good products enter the next step.
[0053] During the entire detection process, the dehumidification mechanism 8 continues to operate to maintain the humidity of the detection environment stable. The exhaust fan 805 rotates, and the outside air is sucked into the dehumidification box 802 through the air inlet holes 803 on both sides of the top of the dehumidification box 802. When the air passes through the space between the partition 807 and the inner wall of the dehumidification box 802, the moisture in it is absorbed by the moisture absorbing member 806. Afterwards, the air enters the area between the two partitions 807 through the connecting hole 808 on the partition 807, and under the guidance of the round-shaped guide plate 809, the air is discharged through the air outlet holes 8010 on both sides of the outside of the dehumidification box 802. This can effectively reduce the humidity in the detection area and significantly improve the accuracy and reliability of the detection data.
[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
