Description

Technical Field

[0001] The present invention relates to the technical field of visual detection, and particularly to a visual detection device with a function of calibrating defective positions. Background Art

[0002] In recent years, with the development of production technology, the production speed of products has gradually increased. As a result, the quality of some of the produced products may not meet the requirements. In order to determine whether the quality of a product meets the requirements, the product can be detected based on machine vision. Visual detection refers to using a machine to replace the human eye for measurement and judgment. Specifically, it means collecting an image of the product to be detected through an image acquisition device, transmitting the image to a dedicated image processing system, and the image processing system performing various operations based on information such as the pixel distribution, brightness, and color of the image to extract the features of the target, and then determining whether the quality of the product meets the requirements according to the features of the target;

[0003] In the prior art, when staff perform defective detection on a pipeline, they usually use a peephole to extend into the pipeline and observe and detect bit by bit. And due to the limitation of the pipeline size, it is impossible to make a calibration at the defective position for convenient later maintenance, thus increasing the time for maintenance and detection and having low efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a visual detection device with a function of calibrating defective positions to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A visual detection device with a function of calibrating defective positions, comprising: a body, one end of the body is provided with a storage cavity, a detection device is slidably connected in the storage cavity, the detection device is used for visual detection, and a support device is arranged on the outer wall of the body, and the support device is used for supporting the body in the pipeline;

[0007] It further includes: a calibration device, the calibration device is arranged on the outer wall of the pipeline, and the calibration device is used for calibrating the defective position;

[0008] The staff places the body into the inner wall of the pipeline, and then installs the calibration device on the outer wall of the pipeline. Subsequently, the staff controls the support device to start through the controller. The support device aligns the central axis of the body with the central axis of the pipeline, making the body in the central position. Then, the staff controls the detection device to start through the controller. After the detection device starts, it slides away from the body side in the storage cavity. The detection device then disengages from the storage cavity. Subsequently, the detection device performs a defect detection on the inner wall of the pipeline, avoiding the staff from manually detecting the inner wall of the pipeline through a peephole and improving the detection efficiency. The staff controls the calibration device to start through the controller. The calibration device moves along the outer wall of the pipeline. During the movement of the calibration device, it drives the body to move, so that the body drives the detection device to move along the central axis of the pipeline, realizing the detection of the inner wall of the pipeline during the movement process, thereby improving the pipeline detection efficiency. When there are defects on the inner wall of the pipeline, the calibration device calibrates on the outer wall of the pipeline corresponding to the defective position inside the pipeline, thus facilitating the staff to quickly locate the defective position and saving the maintenance time.

[0009] Preferably, the detection device includes: hinge plates, the number of the hinge plates is five, and two adjacent hinge plates are connected by hinge rods. A number of detection holes are provided on the hinge plates, and a visual detection module is arranged in each detection hole.

[0010] Preferably, the detection device further includes: an electric cylinder, the electric cylinder is arranged inside the body, the electric cylinder is connected with a push plate, and the push plate is connected with one of the hinge plates; the hinge plates can be folded to form a three-dimensional space, the visual detection module is in a triangular prism shape, and the visual detection modules are combined into a cube after folding;

[0011] When it is necessary to detect the pipeline, the body is propped up under the action of the support device, so that the detection device is located at the central position inside the pipeline. Subsequently, the controller controls the electric cylinder inside the body to start. The electric push rod in the electric cylinder pushes the push plate to move. During the movement of the push plate, it drives the hinge plate to move. During the movement of the hinge plate, it drives the visual detection module to move. When the hinge plate moves to the outermost end away from the body, the controller controls the electric cylinder to stop. Subsequently, the controller controls the visual detection module to start. Since the inner wall of the pipeline is detected, the detection device is in a folded state, and the visual detection module is folded into a cube, and the hinge plates also enclose a cube structure, so that there are four detection holes on the hinge plates in each direction. The visual detection module performs visual detection on the inner wall of the pipeline through the detection holes, enabling the detection device to perform a circular detection on the inner wall of the pipeline, thereby improving the detection efficiency of the inner wall of the pipeline.

[0012] Preferably, the supporting device includes: a support plate, which is arranged around the central axis of the machine body. One side of the support plate is arc-shaped. A number of rolling balls are provided on the surface of the support plate away from the machine body. The rolling balls are slidably connected to the support plate. A placement groove is provided on the surface of the machine body. The support plate is arranged in the placement groove. A folding rod is provided on the side of the support plate close to the placement groove. There are two groups of support plates, and the number of support plates in each group is four;

[0013] After the machine body is placed in the pipeline by the staff, the staff controls the folding rod to lift through the controller. During the lifting process of the folding rod, the folding rod drives the support plate to lift. The support plate disengages from the placement groove and moves to the side away from the placement groove. The support plates arranged around the outer wall of the machine body move synchronously under the action of the folding rod. When the support plate contacts the inner wall of the pipeline, the controller controls the folding rod to stop moving. At this time, the four support plates fix the machine body, making the central axis of the machine body coincide with the central axis of the pipeline, and further making the machine body located at the central position inside the pipeline. Furthermore, the detection device is also at the central position of the pipeline, so that when the visual detection module detects the inner wall of the pipeline, the distances it shines on the inner wall of the pipeline from different angles are the same, avoiding visual distortion differences caused by different distances, thus preventing misjudgment during the detection process and improving the detection accuracy of the inner wall of the pipeline.

[0014] Preferably, the calibration device includes: a mounting ring. A calibration cavity is provided on one side of the mounting ring. A moving cavity is provided on the side of the mounting ring away from the calibration cavity. An expansion rod is arranged around in the moving cavity. A moving roller is rotatably connected to the expansion rod. A motor is provided on the side wall of one of the expansion rods. The drive shaft in the motor passes through the expansion rod to connect the moving roller. An electromagnet is provided on the mounting ring.

[0015] Preferably, a spraying groove is provided in the calibration cavity. A number of nozzles are provided in the spraying groove. The nozzles are arranged around in the spraying groove. A pipeline is provided on the side of the calibration cavity close to the mounting ring. One end of the pipeline is connected to the nozzle, and the other end of the pipeline is connected to a paint tank. A pump is provided in the paint tank.

[0016] Preferably, an electromagnet is provided inside the machine body between the two groups of support plates;

[0017] The staff installs the mounting ring on the outer wall of the pipeline. The telescopic rod drives the moving roller to contact the outer wall of the pipeline. Subsequently, the staff controls the motor on the telescopic rod to start through the controller. The drive shaft in the motor drives the moving roller to rotate. During the rotation of the moving roller, it drives the mounting ring to move along the outer wall of the pipeline. Before the moving roller moves, the controller controls the electromagnets in the mounting ring and in the machine body to start, so that when the moving roller drives the mounting ring to move, the machine body moves under the action of the magnetic force of the electromagnets, thereby realizing the detection of the inner wall of the pipeline when the detection device moves. When the vision detection module detects the inner wall of the pipeline, when the vision detection module detects that there are defects on the inner wall of the pipeline, the vision detection module converts the image signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. Subsequently, the controller controls the pump in the paint tank to start. The pump sends the paint in the paint tank into the pipeline in the mounting ring through the pipeline, and then transports it to the nozzle through the pipeline. Subsequently, the controller controls the nozzle at the corresponding position to open. Subsequently, the calibration paint is ejected from the nozzle. The calibration paint is sprayed from the spraying groove onto the outer wall of the pipeline. The position on the outer wall of the pipeline where it is sprayed corresponds to the position with defects in the corresponding pipeline interior. Thus, during the maintenance process, the staff can quickly find the defective positions on the inner wall of the pipeline, thereby improving the efficiency of pipeline maintenance and saving maintenance time.

[0018] Preferably, the hinge plates can be rotatably combined into a flat plate, and the machine body can be adsorbed on the bracket through an electromagnet;

[0019] When it is necessary to detect the flat plate, the staff controls the electromagnet in the machine body to start through the controller, and then adsorbs the machine body on the bracket. Subsequently, the controller controls the hinge rod to unfold. During the unfolding of the hinge rod, it drives the hinge plate to rotate. The hinge plate unfolds under the action of the hinge rod to form a straight plate. During the unfolding of the hinge plate, it drives the vision detection module to rotate, so that the vision detection module corresponds to the detection hole. When the hinge plate forms a straight plate, at this time, the detection hole is located on the side close to the flat plate, and the detection head of the vision detection module faces the flat plate, thereby realizing the detection of the flat plate, improving the applicability of the detection device, and expanding the detection range of the detection device.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. Since the inner wall of the pipeline is detected, the detection device is in a folded state, and the vision detection module is folded into a cube, and the hinge plates also enclose a cube structure, so that there are four detection holes on the hinge plates in each direction. The vision detection module performs visual detection on the inner wall of the pipeline through the detection holes, enabling the detection device to perform circular detection on the inner wall of the pipeline, thereby improving the detection efficiency of the inner wall of the pipeline.

[0022] 2. During the unfolding process of the articulated rod, the articulated plate is driven to rotate. Under the action of the articulated rod, the articulated plate unfolds to form a straight plate. During the unfolding process of the articulated plate, the visual detection module is driven to rotate, so that the visual detection module corresponds to the detection hole. When the articulated plate forms a straight plate, the detection hole is located on the side close to the flat plate, and the detection head of the visual detection module faces the flat plate, thereby realizing the detection of the flat plate, improving the applicability of the detection device, and expanding the detection range of the detection device.

[0023] 3. The visual detection module converts the image signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. Subsequently, the controller controls the pump in the paint tank to start. The pump sends the paint in the paint tank into the pipeline in the mounting ring through the pipeline, and then transports it to the nozzle through the pipeline. Subsequently, the controller controls the nozzle at the corresponding position to open. Subsequently, the calibration paint is ejected through the nozzle. The calibration paint sprays from the spraying tank onto the outer wall of the pipeline. The sprayed position on the outer wall of the pipeline corresponds to the position where there is a defect in the pipeline interior. Thus, during the maintenance process, the staff can quickly find the defective position on the inner wall of the pipeline, thereby improving the efficiency of pipeline maintenance and saving the maintenance time.

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 Figures 1-7 , the present invention provides a technical solution:

[0038] A visual inspection device with a defect position calibration function comprises: a body 1, a storage cavity 11 is provided at one end of the body 1, a detection device 2 is slidably connected in the storage cavity 11, the detection device 2 is used for visual inspection, and a supporting device 3 is provided on the outer wall of the body 1, the supporting device 3 is used to support the body 1 in a pipeline;

[0039] It also includes: a calibration device 4, which is arranged on the outer wall of the pipeline and is used to calibrate the defective position;

[0040] The staff puts the body 1 into the inner wall of the pipeline, and then installs the calibration device 4 on the outer wall of the pipeline. Then, the staff controls the support device 3 to start through the controller, and the support device 3 makes the central axis of the body 1 coincide with the central axis of the pipeline, so that the body 1 is in the center position. Then, the controller controls the detection device 2 to start. After the detection device 2 is started, it slides from the storage cavity 11 to the side away from the body 1, and the detection device 2 is immediately separated from the storage cavity 11. Then, the detection device 2 performs a defect detection on the inner wall of the pipeline, avoiding the staff manually inspecting the pipeline through the peephole. The inner wall of the pipeline is inspected, which improves the efficiency of inspection. The staff controls the calibration device 4 to start through the controller. The calibration device 4 moves along the outer wall of the pipeline. During the movement of the calibration device 4, the body 1 is driven to move, so that the body 1 drives the detection device 2 to move along the central axis of the pipeline, thereby realizing the inspection of the inner wall of the pipeline during the movement, thereby improving the efficiency of pipeline inspection. When the inner wall of the pipeline is defective, the calibration device 4 is calibrated on the outer wall of the pipeline corresponding to the defective position inside the pipeline, thereby facilitating the staff to quickly locate the defective position and saving maintenance time.

[0041] As a specific embodiment of the present invention, the detection device 2 includes: a hinge plate 21, the number of the hinge plates 21 being five, and adjacent hinge plates 21 being connected by hinge rods. A plurality of detection holes 22 are formed in the hinge plate 21, and a visual detection module 23 is disposed in each detection hole 22.

[0042] As a specific embodiment of the present invention, the detection device 2 further includes: an electric cylinder disposed in the body 1. The electric cylinder is connected to a push plate 24, and the push plate 24 is connected to one of the hinge plates 21. The hinge plates 21 can be folded to form a three-dimensional space. The visual detection module 23 is in a triangular prism shape, and the visual detection modules 23 are combined into a cube after folding.

[0043] As a specific embodiment of the present invention, the hinge plates 21 can be rotatably combined into a flat plate, and the body 1 can be adsorbed on the bracket by an electromagnet;

[0044] When it is necessary to detect a pipeline, the body 1 is supported by the supporting device 3 so that the detection device 2 is located at the central position inside the pipeline. Subsequently, the controller controls the electric cylinder in the body 1 to start, and the electric push rod in the electric cylinder pushes the push plate 24 to move. During the movement of the push plate 24, the hinge plate 21 is driven to move. During the movement of the hinge plate 21, the visual detection module 23 is driven to move. When the hinge plate 21 moves to the outermost end away from the body 1, the controller controls the electric cylinder to stop. Subsequently, the controller controls the visual detection module 23 to start. Since the inner wall of the pipeline is detected, the detection device 2 is in a folded state, and the visual detection modules 23 are folded into a cube, and the hinge plates 21 also enclose a cube structure, so that four detection holes 22 are provided on the hinge plates 21 in each direction. The visual detection module 23 performs visual detection on the inner wall of the pipeline through the detection holes 22, so that the detection device 2 can perform circular detection on the inner wall of the pipeline, thereby improving the detection efficiency of the inner wall of the pipeline.

[0045] When it is necessary to detect a flat plate, the staff controls the electromagnet in the body 1 to start through the controller, and then adsorbs the body 1 on the bracket. Subsequently, the controller controls the hinge rods to unfold. During the unfolding of the hinge rods, the hinge plates 21 are driven to rotate. The hinge plates 21 are unfolded to form a straight plate under the action of the hinge rods. During the unfolding of the hinge plates 21, the visual detection module 23 is driven to rotate, so that the visual detection module 23 corresponds to the detection holes 22. When the hinge plates 21 form a straight plate, the detection holes 22 are located on the side close to the flat plate at this time, and the detection head of the visual detection module 23 faces the flat plate, thereby realizing the detection of the flat plate and improving the applicability of the detection device 2 and expanding the detection range of the detection device 2.

[0046] As a specific embodiment of the present invention, the support device 3 includes: a support plate 31, which is arranged around the central axis of the machine body 1. One side of the support plate 31 is arc-shaped. A plurality of rolling balls are arranged on the surface of the support plate 31 away from the machine body 1. The rolling balls are slidably connected to the support plate 31. A placement groove 32 is arranged on the surface of the machine body 1. The support plate 31 is arranged in the placement groove 32. A folding rod is arranged on the side of the support plate 31 close to the placement groove 32. There are two groups of support plates 31, and the number of each group of support plates 31 is four;

[0047] After the machine body 1 is placed in the pipeline by the staff, the staff controls the folding rod to lift through the controller. During the lifting process of the folding rod, the folding rod drives the support plate 31 to lift. The support plate 31 disengages from the placement groove 32 and moves to the side away from the placement groove 32. The support plates 31 arranged around the outer wall of the machine body 1 move synchronously under the action of the folding rod. When the support plate 31 contacts the inner wall of the pipeline, the controller controls the folding rod to stop moving. At this time, the four support plates 31 fix the machine body 1, so that the central axis of the machine body 1 coincides with the central axis of the pipeline, and further makes the machine body 1 located at the central position inside the pipeline. Furthermore, the detection device 2 is also at the central position of the pipeline, so that when the vision detection module 23 detects the inner wall of the pipeline, the distances when the vision detection module 23 shines on the inner wall of the pipeline from different angles are the same, avoiding visual distortion differences caused by different distances, thereby preventing misjudgment during the detection process, and further improving the detection accuracy of the inner wall of the pipeline.

[0048] As a specific embodiment of the present invention, the calibration device 4 includes: a mounting ring 41. A calibration cavity 42 is opened on one side of the mounting ring 41. A moving cavity 43 is opened on the side of the mounting ring 41 away from the calibration cavity 42. An expansion rod is arranged around in the moving cavity 43. A moving roller 44 is rotatably connected to the expansion rod. A motor is arranged on the side wall of one of the expansion rods. The driving shaft in the motor passes through the expansion rod to connect the moving roller 44. An electromagnet is arranged on the mounting ring 41.

[0049] As a specific embodiment of the present invention, a spraying groove 45 is arranged in the calibration cavity 42. A plurality of nozzles are arranged in the spraying groove 45. The nozzles are arranged around in the spraying groove 45. A pipeline is arranged on the side of the calibration cavity 42 close to the mounting ring 41. One end of the pipeline communicates with the nozzle, and the other end of the pipeline is connected to a pigment tank. A pump is arranged in the pigment tank.

[0050] As a specific embodiment of the present invention, an electromagnet is arranged inside the machine body 1 between the two groups of support plates 31;

[0051] The staff installs the installation ring 41 on the outer wall of the pipeline. The telescopic rod drives the moving roller 44 to contact the outer wall of the pipeline. Subsequently, the staff controls the motor on the telescopic rod to start through the controller. The drive shaft in the motor drives the moving roller 44 to rotate. During the rotation of the moving roller 44, it drives the installation ring 41 to move along the outer wall of the pipeline. Before the moving roller 44 moves, the controller controls the electromagnets in the installation ring 41 and the electromagnets in the machine body 1 to start. When the moving roller 44 drives the installation ring 41 to move, the machine body 1 moves under the action of the magnetic force of the electromagnets, thereby realizing the detection of the inner wall of the pipeline when the detection device 2 moves. When the vision detection module 23 detects the inner wall of the pipeline, when the vision detection module 23 detects that there are defects on the inner wall of the pipeline, the vision detection module 23 converts the image signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. Subsequently, the controller controls the pump in the paint tank to start. The pump sends the paint in the paint tank into the pipeline in the installation ring 41 through the pipeline, and then transports it to the nozzle through the pipeline. Subsequently, the controller controls the nozzle at the corresponding position to open. Subsequently, the calibration paint is sprayed out through the nozzle. The calibration paint is sprayed from the spraying groove 45 onto the outer wall of the pipeline. The sprayed position on the outer wall of the pipeline corresponds to the position with defects in the pipeline interior. Thus, during the maintenance process, the staff can quickly find the defective positions on the inner wall of the pipeline, thereby improving the efficiency of pipeline maintenance and saving maintenance time.

[0052] The working principle of the present invention:

[0053] The staff places the machine body 1 into the inner wall of the pipeline, and then installs the calibration device 4 on the outer wall of the pipeline. After the machine body 1 is placed in the pipeline by the staff, the staff controls the folding rod to lift through the controller. During the lifting process of the folding rod, the folding rod drives the support plate 31 to lift. The support plate 31 disengages from the placement groove 32 and moves to the side away from the placement groove 32. The support plates 31 arranged around the outer wall of the machine body 1 move synchronously under the action of the folding rod. When the support plate 31 contacts the inner wall of the pipeline, the controller controls the folding rod to stop moving. At this time, the four support plates 31 fix the machine body 1, making the central axis of the machine body 1 coincide with the central axis of the pipeline, thereby making the machine body 1 located at the central position inside the pipeline, and further making the detection device 2 also at the central position of the pipeline. When the vision detection module 23 detects the inner wall of the pipeline, when the vision detection module 23 shines on the inner wall of the pipeline from different angles, the distances it shines on are the same, avoiding visual distortion differences caused by different distances, thus preventing misjudgment during the detection process;

[0054] When the pipeline needs to be detected, the body 1 is propped up by the support device 3, so that the detection device 2 is located at the central position inside the pipeline. Subsequently, the controller controls the electric cylinder inside the body 1 to start, and the electric push rod in the electric cylinder pushes the push plate 24 to move. During the movement of the push plate 24, it drives the articulated plate 21 to move. During the movement of the articulated plate 21, it drives the vision detection module 23 to move. When the articulated plate 21 moves to the outermost end away from the body 1, the controller controls the electric cylinder to stop. Subsequently, the controller controls the vision detection module 23 to start. Since the inner wall of the pipeline is detected and the detection device 2 is in a folded state, the vision detection module 23 is folded into a cube, and the articulated plate 21 also encloses a cube structure, so that four detection holes 22 are provided on the articulated plate 21 in each direction. The vision detection module 23 performs visual detection on the inner wall of the pipeline through the detection holes 22, enabling the detection device 2 to perform circular detection on the inner wall of the pipeline, thereby improving the detection efficiency of the inner wall of the pipeline.

[0055] When the flat plate needs to be detected, the staff controls the electromagnet inside the body 1 to start through the controller, and then adsorbs the body 1 on the bracket. Subsequently, the controller controls the articulated rod to unfold. During the unfolding process of the articulated rod, it drives the articulated plate 21 to rotate. The articulated plate 21 unfolds under the action of the articulated rod to form a straight plate. During the unfolding process of the articulated plate 21, it drives the vision detection module 23 to rotate, so that the vision detection module 23 corresponds to the detection hole 22. When the articulated plate 21 forms a straight plate, at this time the detection hole 22 is located on the side close to the flat plate, and the detection head of the vision detection module 23 faces the flat plate, thereby realizing the detection of the flat plate and improving the applicability of the detection device 2 and expanding the detection range of the detection device 2.

[0056] The staff installs the mounting ring 41 on the outer wall of the pipeline. The telescopic rod drives the moving roller 44 to contact the outer wall of the pipeline. Subsequently, the staff controls the motor on the telescopic rod to start through the controller. The drive shaft in the motor drives the moving roller 44 to rotate. During the rotation of the moving roller 44, it drives the mounting ring 41 to move along the outer wall of the pipeline. Before the moving roller 44 moves, the controller controls the electromagnets in the mounting ring 41 and the electromagnets in the machine body 1 to start, so that when the moving roller 44 drives the mounting ring 41 to move, the machine body 1 moves under the action of the electromagnetic force of the electromagnets, thereby realizing the detection of the inner wall of the pipeline when the detection device 2 moves. When the vision detection module 23 detects the inner wall of the pipeline, when the vision detection module 23 detects that there are defects on the inner wall of the pipeline, the vision detection module 23 converts the image signal into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. Subsequently, the controller controls the pump in the paint tank to start. The pump sends the paint in the paint tank into the pipeline in the mounting ring 41 through the pipeline, and then transports it to the nozzle through the pipeline. Subsequently, the controller controls the nozzle at the corresponding position to open. Subsequently, the calibration paint is ejected through the nozzle. The calibration paint is sprayed from the spraying groove 45 onto the outer wall of the pipeline. The position on the outer wall of the pipeline where it is sprayed corresponds to the position with defects in the pipeline interior, so that the staff can quickly find the defective position on the inner wall of the pipeline during the maintenance process.
