Description

Technical Field

[0001] The present invention relates to the technical field of machine vision detection equipment, and in particular to a machine vision detection device based on machine learning. Background Art

[0002] In the wave of industrial automation production, rapid and accurate inspection of materials has always been the core link to ensure product quality and production efficiency. Although traditional manual inspection methods can meet basic inspection needs to a certain extent, their inherent limitations are becoming increasingly prominent. Manual inspection is not only time-consuming and labor-intensive, but also inefficient, and is easily affected by human factors, such as fatigue and vision differences. These factors may make it difficult to effectively guarantee inspection accuracy and consistency. Therefore, seeking a more efficient and accurate inspection method has become an urgent problem to be solved in the field of industrial automation.

[0003] In order to overcome the shortcomings of manual inspection, technical personnel in this field have developed machine vision inspection devices through unremitting efforts. The emergence of such devices marks that industrial automated inspection has entered a new stage. Most of the existing machine vision inspection devices adopt a design that combines a 6-axis robot with a CCD camera. In actual applications, the 6-axis robot can flexibly drive the CCD camera to take all-round photos of the top and sides of the material, thereby realizing visual inspection of material appearance, size, defects and other aspects.

[0004] However, although the existing machine vision inspection devices have improved the inspection efficiency and accuracy to a certain extent, their high cost has become a key factor restricting their widespread application. The 6-axis robot, as the core component of the device, has a complex mechanical structure and built-in multiple motors and multiple sensors, which leads to high procurement costs. In addition, since the control logic of the 6-axis robot is relatively complex, it requires the use of a dedicated control program for operation, which undoubtedly increases the difficulty of operation and training costs. What is more serious is that the sensor, as an important component of the 6-axis robot, is vulnerable to damage, which leads to an increase in maintenance frequency and an increase in maintenance costs, which brings a considerable burden to the company's production and operation. Summary of the invention

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The following describes a machine vision detection device based on machine learning according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 8 As shown, the machine vision detection device based on machine learning in an embodiment of the present invention includes: Visual inspection frame 1: fixedly mounted on the conveying mechanism 10; Visual inspection component 2: includes a single-drive five-way component 21, a camera 22 with a built-in timing unit, and a zoom adjustment component 23. The single-drive five-way component 21 is arranged on the visual inspection frame 1. The camera 22 is arranged on the single-drive five-way component 21 and is located on one side of the top of the workbench 12 where the material 11 is fixed in the conveying mechanism 10. The zoom adjustment component 23 is respectively arranged on the camera 22, the single-drive five-way component 21 and the visual inspection frame 1, and one end of the zoom adjustment component 23 is respectively connected to the zoom ring and the focus ring in the camera 22; The single-drive five-way component 21 is electrically connected to an external power source, and the camera 22 and the conveying mechanism 10 are respectively connected to an external controller through a bus system to achieve data transmission and reception of control instructions.

[0022] It should be noted that the external power supply described in this embodiment also supplies power to the external controller.

[0023] It should also be noted that the conveying mechanism 10 described in this embodiment has a built-in encoder, which is used to detect the number of rotations of the conveying motor in the conveying mechanism 10 in real time, and send the number of rotations data to an external controller. The external controller determines the position of the workbench 12 and the material 11 based on the number of rotations data, wherein the material 11 is fixed at the top center of the workbench 12.

[0024] Specifically, the present invention has a reasonable structure and is only equipped with one motor and one timing unit, so that it can drive the camera 22 to efficiently complete the shooting task of the preset positions on the top and side of the material 11, and can also easily realize the flexible switching between the long-range overall shooting and the close-up zoom shooting. This design not only simplifies the operation process and makes the control extremely simple, but also greatly saves the production cost and is convenient for maintenance operation, which greatly enhances the practicality and has a good use effect. The present invention innovatively integrates a single-drive five-way component 21, which is driven by only a single high-performance motor and cooperates with other components to accurately control the camera 22, and flexibly shoots the top and side of the material 11 according to the preset trajectory to ensure the stability and consistency of the shooting quality. This single motor design not only shows excellent performance stability, but also greatly reduces the production cost and simplifies the production process. At the same time, this design is not only easy to operate and control, but also greatly improves the quality of the material 11. It has greatly promoted the subsequent maintenance and repair work, and the overall use effect is remarkable, showing extremely high application value. The single-drive five-way component 21 of the present invention innovatively integrates the fixed-point trigger mechanism 100, which can intelligently identify the position of the material 11, and automatically adjust the start and stop of the motor to ensure that the single-drive five-way component 21 and the camera 22 cooperate with the conveying mechanism 10 to operate smoothly, maintain the continuity of the detection process, and significantly improve the use effect. The present invention is also provided with a zoom adjustment component 23. The zoom adjustment component 23 can synchronously adjust the zoom and focus rings when the camera 22 moves, automatically complete the zoom and focus operations, and realize rapid switching of focal length. This function enables the camera 22 to easily switch between long-range overall shooting and close-up magnified shooting. The former is conducive to comprehensive detection of the volume of the material 11, and the latter accurately captures the defect characteristics of the surface of the material 11, which significantly improves the detection effect and practicality, and has a good use effect.

[0025] Specifically, when in use, the conveying mechanism 10 operates according to the instruction, and the operation of the conveying mechanism 10 drives the workbench 12 fixed with the material 11 to move from the loading end to the lower feeding end. When the workbench 12 fixed with the material 11 is transported to the position of the fixed-point trigger mechanism 100 and triggers the fixed-point trigger mechanism 100 to operate, the conveying mechanism 10 receives the instruction to stop operating. This position data can be obtained through the encoder built into the conveying mechanism 10. After the conveying mechanism 10 stops operating, the positions of the workbench 12 and the material 11 remain unchanged. The operation of the fixed-point trigger mechanism 100 enables the power-on circuit of the drive motor 2120 in the single-drive five-way component 21 to be energized, and the drive motor 2120 is powered on and operates, and cooperates with other components to accurately control the camera 22, and flexibly shoot the material 1 according to the preset trajectory. 1 top and side, that is, first drive the camera 22 to move downward to a set height, and during the downward movement, the camera 22 synchronously shoots the long-range overall view of the top of the material 11, and the shooting time is controlled by the timing unit of the camera 22, and then move diagonally downward, so that it moves from the top of the material 11 to the side of the material 11, and changes its rotation angle when it moves downward to the set height, so that it changes from a vertical state to a horizontal state, which is convenient for shooting the side of the material 11, and after the angle is adjusted, drive the camera 22 to rotate with the material 11 as the center, and shoot the material 11 360°. During the rotation process, the camera 22 synchronously shoots the long-range overall view of the preset position on the side of the material 11. This function can be achieved by setting the shooting time. To ensure the shooting quality, it is necessary to control the drive motor 2120 to run at a constant speed, and drive the camera 22 to reset to the initial point of rotation after 360° shooting. During the resetting process, the zoom adjustment component 23 is passively triggered and adjusts the zoom ring and focus ring of the camera 22 to change its focal length, so that it changes from long-range overall shooting to close-up zoom shooting, and after changing to close-up zoom shooting, a close-up zoom shooting is performed on a preset position on the side of the material 11. After the camera 22 is reset to the initial point of rotation, it begins to move diagonally upward, so that it moves from one side of the material 11 to the top of the material 11, and changes its rotation angle during the upward movement, so that it changes from a horizontal state to a vertical state, which is convenient for close-up zoom shooting of the top of the material 11. The camera 22 moves to the material 11 After reaching the top, the camera 22 synchronously performs a close-up zoom shot of the top of the material 11. After the top shooting is completed, the camera 22 continues to move up and triggers the zoom adjustment component 23 to operate. The zoom adjustment component 23 operates to adjust the zoom ring and focus ring of the camera 22 again to change its focal length, so that it changes from close-up zoom shooting to long-range overall shooting, which is convenient for the next shooting. When the camera 22 is reset to the origin, the conveying mechanism 10 operates according to the instruction and continues to drive the workbench 12 to move toward the lower material end. After the workbench 12 moves, the fixed-point trigger mechanism 100 separates from the workbench 12 and stops running. After the fixed-point trigger mechanism 100 stops running, it disconnects the power circuit of the drive motor 2120, so that the drive motor 2120 is powered off and stops running.This ensures that the camera 22 remains at the origin.

The descent of the rotating frame 215 also synchronously drives the key rod 214 to vertically descend along the inner wall of the key cylinder 212, and synchronously drives the lifting rod 216 to vertically descend along the inner wall of the limit cylinder 213. At this time, the operation of the single-drive mechanism 200 drives the rotating frame 21 The downward force is greater than the resistance of the damping ring 217, so that the lifting rod 216 can be pulled out. During the descending process of the rotating frame 215, the push rod 2111 is synchronously descended and separated from the bottom of the rotating disk 211. Under the elastic force of the first spring 2112, it drives the push rod 2111 to move upward. The upward movement of the push rod 2111 synchronously drives the first convex shaft 2114 to move upward along the inner wall of the first spiral guide groove 2115, and synchronously drives the first rotating cylinder 2113 to rotate. The rotation of the first rotating cylinder 2113 synchronously drives the driving gear 2116 to rotate. The rotation of the driving gear 2116 synchronously drives the sliding frame 2118 to move along the surface of the T-shaped seat 2117 toward one side close to the visual inspection frame 1. The movement of the sliding frame 2118 synchronously drives the camera 2113 to rotate. The camera 22 moves from the top of the material 11 to the oblique lower part of the material 11. When the adjusting gear 2119 on the slide frame 2118 contacts and meshes with the teeth on the T-shaped seat 2117, the camera 22 is synchronously driven to rotate, so that it changes from a vertical state to a horizontal state, so as to shoot the side of the material 11. When the camera 22 changes from a vertical state to a horizontal state, the conical elastic clamp on the lifting rod 216 is synchronously engaged and fixed with the clamping hole 218. After the conical elastic clamp is engaged and fixed with the clamping hole 218, the position of the lifting rod 216 is restricted, and the rotating frame 215 is synchronously driven to be fixed. After the rotating frame 215 is fixed, as the single-drive mechanism 200 continues to operate, the elastic clamping rod 2123 continues to descend. The clamping force between the elastic clamping piece and the clamping hole 218 is greater than the elastic force of the built-in spring of the elastic clamping rod 2123. Therefore, the elastic clamping rod 2123 is separated from the through groove 2110 under the drive of the single-drive mechanism 200, and continues to move downward along the side guide part 219 until it is separated from the side guide part 219 and enters the strip groove opened at the top of the conveying mechanism 10. When the elastic clamping rod 2123 enters the strip groove, the single-drive mechanism 200 synchronously drives the key cylinder 212 to rotate, and the rotation of the key cylinder 212 synchronously drives the key rod 214, the rotating frame 215, the lifting rod 216, the limit cylinder 213 and the turntable 211 to rotate. The rotation of the rotating frame 215 drives the camera 22 to move, and takes 360° photos of the side of the material 11.

[0031] Specifically, the structure and connection relationship of the single drive mechanism 200 are further described. When in use, the drive motor 2120 is powered on and runs, and the drive motor 2120 runs and synchronously drives the reciprocating screw 2121 to rotate. The reciprocating screw 2121 rotates and synchronously drives the slide 2122, the elastic clamping rod 2123 and the fixed rod 2124 to move downward. The elastic clamping rod 2123 moves downward into the side guide part 219. When the elastic clamping rod 2123 separates from the side guide part 219 and enters the conveying mechanism, After entering the strip groove at the top of 10, the fixing rod 2124 enters into the second spiral guide groove 2126 on the surface of the second rotating cylinder 2125, and moves downward along the inner wall of the second spiral guide groove 2126, and synchronously drives the second rotating cylinder 2125 to rotate. The rotation of the second rotating cylinder 2125 cooperates with the transmission rod 2129, the synchronous gear 2127 and the synchronous toothed belt 2128 to synchronously drive the key cylinder 212 to rotate. The rotation of the key cylinder 212 synchronously drives the key rod 214 and the rotating frame 215 to rotate.

[0032] In one embodiment of the present invention, Figure 5As shown, the side guide portion 219 includes an inner oblique guide portion 2191, a vertical portion 2192 and an outer oblique guide portion 2193. The inner oblique guide portion 2191, the vertical portion 2192 and the outer oblique guide portion 2193 are integrally formed and symmetrically opened on the surface of the rotating frame 215 from the inside to the outside, and are located on the outside of the through groove 2110. One end of the elastic clamping rod 2123 is slidingly connected to the surfaces of the inner oblique guide portion 2191, the vertical portion 2192 and the outer oblique guide portion 2193 respectively, and one end of the elastic clamping rod 2123 is clamped and fixed to the inner wall of the through groove 2110.

[0033] Specifically, the structure and connection relationship of the side guide portion 219 are further explained, and the inner oblique guide portion 2191, the vertical portion 2192 and the outer oblique guide portion 2193 are provided to facilitate one end of the elastic clamping rod 2123 to smoothly enter the side guide portion 219 and the through groove 2110, and to smoothly move out of the through groove 2110 and the side guide portion 219, thereby achieving a good use effect.

[0034] In one embodiment of the present invention, Figure 6 As shown, the driving motor 2120 also includes a fixed-point trigger mechanism 100, which includes a seat body 101, a rod body 102, a second spring 103, a power connection block 104 and a power connection seat 105, wherein: The seat 101 is fixedly connected to the surface of the visual inspection frame 1 and overlapped on the top of the conveying mechanism 10.

One end of the rod 102 passes through the outside of the seat 101 and is located inside the V-shaped groove 13 opened on the surface of the workbench 12. The end of the rod 102 that passes through the outside of the seat 101 is slidably connected to the inner wall of the V-shaped groove 13, and the other end of the rod 102 is fixedly connected to the power connection block 104. The power socket 105 is fixedly connected to the inner wall of the socket body 101 and is arranged on the power circuit of the drive motor 2120. The power connection block 104 corresponds to the position of the power socket 105 and is slidably connected to the inner wall of the power socket 105. When the power connection block 104 contacts the power socket 105, the power circuit of the drive motor 2120 is energized, and the drive motor 2120 is powered on and runs. When the power connection block 104 is separated from the power socket 105, the power circuit of the drive motor 2120 is de-energized, and the drive motor 2120 stops running.

[0035] Specifically, the structure and connection relationship of the fixed-point trigger mechanism 100 are further explained. The mechanism can intelligently identify the position of the material 11, automatically control the start and stop of the motor, ensure the smooth operation of the single-drive five-way component 21 and the camera 22 to coordinate the conveying mechanism 10, maintain the continuity of the detection process, and significantly improve the use effect.

[0036] During use, after the rod body 102 enters the V-shaped groove 13 on the surface of the workbench 12, it is squeezed by the inner wall of the V-shaped groove 13, and one end of the rod body 102 retracts toward the inside of the seat body 101 and squeezes the second spring 103. When one end of the rod body 102 moves to the shallowest point of the V-shaped groove 13, one end of the rod body 102 synchronously drives the power connection block 104 to enter the power connection socket 105 and contact the inner wall of the power connection socket 105. When the power connection block 104 contacts the power connection socket 105, the power circuit of the drive motor 2120 is energized, and the drive motor 2120 is powered on and runs. When one end of the rod body 102 moves out of the shallowest point of the V-shaped groove 13, the power connection block 104 is separated from the power connection socket 105, the power circuit of the drive motor 2120 is de-energized, and the drive motor 2120 stops running.

[0037] In one embodiment of the present invention, Figure 4 As shown, the camera 22 also includes a mounting base 220, the camera 22 is clamped and fixed on the inner wall of the mounting base 220, one end of the central axis of the adjusting gear 2119 is fixedly connected to the surface of the mounting base 220, and the zoom adjustment component 23 is respectively arranged on the mounting base 220, the turntable 211 and the visual inspection frame 1.

[0038] Specifically, the installation seat 220 is provided to facilitate the disassembly and assembly of the camera 22 and the gear dual adjustment mechanism 231, and also provides a certain degree of protection for the camera 22, resulting in a good use effect.

[0039] In one embodiment of the present invention, Figure 1-Figure 4 and Figure 7 As shown, the zoom adjustment assembly 23 includes a gear dual adjustment mechanism 231, a reset gear rod 232 and an arc-shaped adjustment gear plate 233. The gear dual adjustment mechanism 231 is arranged on the inner wall of the mounting seat 220. One end of the gear dual adjustment mechanism 231 is respectively connected to the zoom ring and the focus ring on the camera 22. The other end of the gear dual adjustment mechanism 231 passes through the outside of the mounting seat 220 and is respectively meshed with the reset gear rod 232 fixedly connected to the bottom of the turntable 211 and the arc-shaped adjustment gear plate 233 fixedly connected to the surface of the visual inspection frame 1.

[0040] Specifically, the structure and connection relationship of the zoom adjustment component 23 are further explained. When the camera 22 moves, the zoom adjustment component 23 can synchronously control the zoom and focus rings, automatically complete the zoom and focus operations, and realize rapid switching of focal length. This function enables the camera 22 to easily switch between long-range overall shooting and close-up magnified shooting. The former is conducive to comprehensive detection of the volume of the material 11, and the latter accurately captures the defect characteristics of the surface of the material 11, which significantly improves the detection effect and practicality, and has a good use effect.

[0041] When in use, the mounting seat 220 moves downward and synchronously drives the gear double adjustment mechanism 231 to move downward. After the gear double adjustment mechanism 231 moves downward, it separates from the reset gear rod 232. Then the mounting seat 220 changes direction and drives the camera 22 to shoot a circle with the material 11 as the center. During this process, the gear double adjustment mechanism 231 contacts the arc-shaped adjustment tooth plate 233. Since the gear double adjustment mechanism 231 has a built-in one-way transmission 2313, the positions of the zoom ring and the focus ring on the camera 22 remain unchanged. After the camera 22 shoots a circle with the material 11 as the center, it starts to reset. During this process, the gear double adjustment mechanism 231 contacts the arc-shaped adjustment tooth plate 233 again. 3 are in contact and trigger the gear double adjustment mechanism 231 to run. The gear double adjustment mechanism 231 runs to adjust the zoom ring and the focus ring on the camera 22 to change it from long-range overall shooting to close-up zoom shooting. Then the mounting base 220 moves up and drives the camera 22 to reset. During the resetting process of the camera 22, the gear double adjustment mechanism 231 contacts the reset gear rod 232 and touches the gear double adjustment mechanism 231 again to run. The gear double adjustment mechanism 231 runs to adjust the zoom ring and the focus ring on the camera 22 to change it from close-up zoom shooting to long-range overall shooting, which is convenient for the next material 11 shooting.

[0042] In one embodiment of the present invention, Figure 7 As shown, the gear dual adjustment mechanism 231 includes a semi-external gear 2311, a worm 2312, a one-way transmission 2313, a worm wheel 2314, a synchronization shaft 2315, a first rotating gear 2316 and a second rotating gear 2317, wherein: The semi-external gear 2311 is rotatably connected to the inner wall of the mounting seat 220, one end of the semi-external gear 2311 passes through the outside of the mounting seat 220, and is respectively meshed with the reset gear rod 232 and the arc-shaped adjustment gear plate 233. The worm 2312 is rotatably connected to the inner wall of the mounting seat 220 and is located on one side of the semi-external gear 2311. The worm 2312 is connected to the semi-external gear 2311 through a one-way transmission 2313. The worm wheel 2314 is rotatably connected to the inner wall of the mounting seat 220 and is meshed with the worm 2 312 are meshed with each other, the synchronization shaft 2315 is rotatably connected to the inner wall of the mounting base 220 and is located on one side of the camera 22, one end of the synchronization shaft 2315 is fixedly connected to the surface of the worm gear 2314, the first rotating gear 2316 and the second rotating gear 2317 are fixedly connected to the surface of the synchronization shaft 2315 up and down, and the first rotating gear 2316 and the second rotating gear 2317 are respectively meshed with the zoom gear ring 2210 and the focus gear ring 2220 which are sleeved on the outside of the zoom ring and the focus ring.

[0043] It should be noted that the one-way transmission 2313 described in this embodiment is a ratchet one-way transmission.

[0044] Specifically, the structure and connection relationship of the gear double adjustment mechanism 231 are further explained. When in use, the mounting seat 220 moves downward and synchronously drives the semi-external gear 2311 to move downward. Since the semi-external gear 2311 is meshed and connected with the reset gear rod 232, the semi-external gear 2311 rotates synchronously during the downward movement. Since a one-way transmission device 2313 is provided, the rotation of the semi-external gear 2311 does not drive the worm 2312 to rotate, and the positions of the zoom ring and the focus ring remain unchanged. At this time, the camera 22 is in a long-range overall shooting state. When the camera 22 changes from a vertical state to a horizontal state, the rotating frame 215 rotates synchronously and drives the camera 22 to shoot a circle with the material 11 as the center, and performs 360-degree shooting of the side of the material 11. ° Take pictures. During this process, the semi-external gear 2311 contacts and meshes with the arc-shaped adjusting tooth plate 233, and rotates synchronously. Since a one-way transmission device 2313 is provided, the rotation of the semi-external gear 2311 will not drive the worm 2312 to rotate, and the zoom ring and the focus ring will remain in position. At this time, the camera 22 is still in the long-range overall shooting state. The long-range overall shooting is convenient for detecting the volume of the material 11. The shooting time is controlled by the timing unit. The shooting position is accurately controlled by accurately controlling the shooting time. When the rotating frame 215 rotates one circle, it starts to reset. The reset of the rotating frame 215 synchronously drives the camera 22 to reset. During the reset process, the semi-external gear 2311 contacts and meshes with the arc-shaped adjusting tooth plate 233 again, and rotates synchronously. The semi-external gear 2311 in the reset state rotates synchronously through the one-way transmission 2313 to drive the worm 2312 to rotate, the rotation of the worm 2312 synchronously drives the worm wheel 2314, the synchronization shaft 2315, the first rotating gear 2316 and the second rotating gear 2317 to rotate, the rotation of the first rotating gear 2316 and the second rotating gear 2317 synchronously drives the zoom gear ring 2210 and the focus gear ring 2220 to rotate, the rotation of the zoom gear ring 2210 and the focus gear ring 2220 synchronously drives the zoom ring and the focus ring to rotate, and the focal length and focus are automatically adjusted. After the zoom ring and the focus ring are adjusted, the camera 22 is in a close-up magnification state, which is convenient for taking pictures of the defect features on the surface of the material 11. When the mounting seat 220 moves up The semi-external gear 2311 is synchronously driven to move upward. When the semi-external gear 2311 contacts and meshes with the reset gear rod 232, it rotates synchronously and drives the worm 2312 to rotate synchronously through the one-way transmission 2313. The rotation of the worm 2312 synchronously drives the worm wheel 2314, the synchronization shaft 2315, the first rotating gear 2316 and the second rotating gear 2317 to rotate. The rotation of the first rotating gear 2316 and the second rotating gear 2317 synchronously drives the zoom gear ring 2210 and the focus gear ring 2220 to rotate. The rotation of the zoom gear ring 2210 and the focus gear ring 2220 synchronously drives the zoom ring and the focus ring to rotate, so as to automatically adjust the focal length and focus. After the zoom ring and the focus ring are adjusted, the camera 22 is in a long-range overall shooting state.It is convenient for the next shooting of material 11.

[0045] In summary, the machine vision inspection device based on machine learning in the embodiment of the present invention has a reasonable structure. It is only equipped with one motor and one timing unit, so it can drive the camera 22 to efficiently complete the shooting task of the preset positions on the top and side of the material 11, and can also easily realize the flexible switching between the overall long-range shooting and the close-up magnified shooting. This design not only simplifies the operating process and makes the control extremely simple, but also greatly saves production costs, facilitates maintenance operations, greatly enhances practicality, and has a good use effect.
