In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] like Figures 1 to 9As shown, the present invention provides a defect detection device, which automatically grabs the workpiece and places it in a designated area for detection, without manual intervention in the middle, and is easy to install and disassemble. The defect detection device includes a housing 1, a feed conveying mechanism 2, a grabbing mechanism 3, a detection mechanism 4, a tooling platform 5 and a discharge conveying mechanism 6. The feed conveying mechanism 2 is fixed to the housing 1 and is used to convey the feed box 100 containing the workpiece; the grabbing mechanism 3 is fixed in the housing 1, and the grabbing mechanism 3 includes a first mechanical arm 31 and a grabbing member 32. The first mechanical arm 31 has six degrees of freedom. The grabbing member 32 is connected to the output end of the first mechanical arm 31 and is used to grab the workpiece. In this embodiment, the grabbing member 32 is a pneumatic finger with fast response and stable clamping. The specific structure of the pneumatic finger belongs to the mature technology in the relevant field, and this embodiment will not be repeated.

[0051] The detection mechanism 4 is fixed in the casing 1, and the detection mechanism 4 includes a second robotic arm 41 and a first intelligent visual detection component 42. The second robotic arm 41 has six degrees of freedom. The first intelligent visual detection component 42 is connected to the output end of the second robotic arm 41 for performing two-dimensional image detection on the workpiece; the tooling platform 5 is fixed in the casing 1 for carrying and limiting the position of the workpiece; the discharge conveying mechanism 6 is passed through and fixed in the casing 1 for conveying the discharge box 200 containing the workpiece.

[0052] When inspecting standard parts, workpieces with relatively regular shapes or non-standard workpieces, the feed box 100 enters the housing 1 through the feed conveying mechanism 2, the workpiece in the feed box 100 is grabbed by the gripping mechanism 3, and the workpiece is subjected to two-dimensional image detection by the detection mechanism 4. Specifically, the shape and color of the workpiece are analyzed by shooting and deep learning to detect defects such as scratches and processing defects. Since the first mechanical arm 31 in the gripping mechanism 3 has six degrees of freedom, and the second mechanical arm 41 in the detection mechanism 4 has six degrees of freedom, the combination of the two can achieve a twelve-degree-of-freedom posture conversion, and most of the outer surface of the workpiece can be inspected. After the inspection, the gripping mechanism 3 places the workpiece on the tooling platform 5, and inspects the obstructed part of the workpiece when the gripping mechanism 3 grips it, thereby realizing a comprehensive and all-round inspection of the outer surface of the workpiece. Therefore, the defect detection equipment has a high degree of flexibility, and can perform all-round inspection on workpieces of different types and specifications, regardless of whether the shape of the inspected workpiece is regular, so that the scope of application is wide and the compatibility is high. In addition, the machine vision is used to perform two-dimensional scanning and detection of the workpiece, so that the accuracy and adaptability of the detection are higher. In addition, the feeding conveying mechanism 2, the grasping mechanism 3, the detection mechanism 4, the tooling platform 5 and the discharging conveying mechanism 6 in the defect detection device have separate functions and are all detachably connected to the housing 1 in the form of a seat body, which can realize flexible installation.

[0053] After inspecting the workpiece, the inspection mechanism 4 will feed back the result to the grasping mechanism 3. The workpiece with qualified inspection result will be placed in the discharge box 200 by the grasping mechanism 3, and then output to the outside of the casing 1 through the discharge conveying mechanism 6. The workpiece with unqualified inspection result will be put back into the feed box 100, and then output to the outside of the casing 1 in reverse through the feed conveying mechanism 2.

[0054] Optionally, in this embodiment, the defect detection device further includes a posture recognition mechanism 7, which is fixed in the housing 1 and is used to scan and analyze the three-dimensional contour features of the workpieces in the feed box 100 through three-dimensional vision, and the posture recognition mechanism 7 is communicatively connected with the grasping mechanism 3. The three-dimensional contour features of the workpieces in the feed box 100 are scanned and analyzed through three-dimensional vision, and the information is transmitted to the grasping mechanism 3. The grasping mechanism 3 can adjust the grasping point, and can accurately grasp a certain fixed position set for the disorderly placed workpieces in the feed box 100, so as to realize the automatic grasping of the whole box of workpieces, reduce the intervention of personnel, and facilitate the subsequent two-dimensional image detection of the workpieces.

[0055] Alternatively, if Figure 5 As shown, both the feed conveying mechanism 2 and the discharge conveying mechanism 6 include an active conveying component 20 and an auxiliary component 30. The active conveying component 20 includes a first support 201, a first driving member 202 and a belt 203. In this embodiment, the first driving member 202 is a motor. The first support 201 is fixed in the housing 1. The first driving member 202 is fixed to the first support 201. The first driving member 202 is connected to the belt 203 by transmission. The auxiliary component 30 is located outside the housing 1. The auxiliary component 30 includes a second support 301 and a plurality of rollers 302. The second support 301 is fixed to the first support 201. The plurality of rollers 302 are spaced and rotatably arranged on the second support 301. The auxiliary component 30 is provided to facilitate the operator to place the feed box 100 or the discharge box 200, and can provide a buffer time to make the placement of the box more stable. The operator places the material box on the roller 302, and pushes the material box into the housing 1 with the help of the rolling force of the roller 302, and then pushes it to the active conveying component 20, and then transports the material box to the grasping mechanism 3 and the detection mechanism 4 through the active conveying component 20. In this process, the auxiliary component 30 uses the roller 302, which is flexible in rolling and easy to operate; the active conveying component 20 conveys the material box through the belt drive, which can increase the friction between the material box and the active conveying component 20, and facilitate the transition of the material box from the auxiliary component 30 to the active conveying component 20. In other embodiments, the auxiliary component 30 may not be provided, and the active conveying component 20 may also include a motor and multiple rollers, and the motor drives the multiple rollers to rotate.

[0056] Optionally, the feed conveying mechanism 2 and the discharge conveying mechanism 6 also include a limit assembly 40, which includes a second driving member 401 and a limit assembly 402. The second driving member 401 is fixed to the first support 201, and the limit assembly 402 is connected to the second driving member 401 by transmission, and is arranged between the belt 203 and the roller 302. The limit assembly 402 can rotate and can press the feed box 100 or the discharge box 200 against the first support 201. Before the material box moves from the auxiliary component 30 to the active conveying component 20, the limit assembly 402 rotates to avoid interference with the material box. After the material box enters the active conveying component 20, the limit assembly 402 rotates and presses the material box against the first support 201 to limit the position of the material box. With such an arrangement, when the grabbing mechanism 3 and the detection mechanism 4 accidentally touch the material box, the displacement of the material box can be avoided.

[0057] Optionally, in this embodiment, the second driving member 401 is a rotary clamping cylinder. While the rotary clamping cylinder drives the limit member 402 to rotate, it can also realize the linear movement of the limit member 402. After the material box enters the active conveying component 20, the rotary clamping cylinder first drives the limit member 402 to rotate, and then drives the limit member 402 to move linearly in the direction close to the material box, and abuts against the limit member 402, thereby making the material box abut against the first support 201. Such an arrangement can avoid friction between the limit member 402 and the material box when it rotates. In other embodiments, the first driving member 202 can be a motor, or a combination of a motor and a linear driving member, and the linear driving member can be an electric push rod or a cylinder.

[0058] In this embodiment, the first support 201 includes a support body, a guide member 2011 and an abutment member 2012. The two guide members 2011 are fixed to the support body and are located on both sides of the belt 203. The feed box 100 or the discharge box 200 is slidably connected to the guide member 2011 to guide the transportation of the material box. The abutment member 2012 is fixed to the support body and is located on the side of the support body away from the auxiliary component 30. The limiting member 402 can press the feed box 100 or the discharge box 200 against the abutment member 2012 to achieve a better limiting effect.

[0059] Alternatively, if Figure 8As shown, the first intelligent visual inspection component 42 includes a first bracket 421, a first camera component and a light source component. The first bracket 421 is connected to the output end of the second mechanical arm 41. The first camera component and the light source component are fixed to the first bracket 421 from the inside to the outside. The first camera component includes a first camera 424 and a first lens 425, and the first lens 425 is fixed to the first camera 424. When the first camera component shoots the workpiece, the workpiece is illuminated by the light source component. Optionally, the light source component includes a coaxial light source component 422 and an annular light source component 423, and the coaxial light source component 422 and the annular light source component 423 are arranged in sequence from the inside to the outside. Alternatively, the light source component includes a coaxial light source component 422 and a bowl light source component, and the coaxial light source component 422 and the bowl light source component are arranged in sequence from the inside to the outside. The combination of the coaxial light source component 422 and the annular light source component 423 or the combination of the coaxial light source component 422 and the bowl light source component can provide more uniform and comprehensive illumination, thereby improving the accuracy and efficiency of detection.

[0060] Alternatively, if Figure 6 and Figure 7 As shown, the defect detection device further includes a second intelligent visual detection component 8, which is fixed in the housing 1 and is used to perform two-dimensional image detection on the discharge box 200. The discharge box 200 on the discharge conveying mechanism 6 must be an empty box before detection to place the workpieces that have passed the detection. In this embodiment, by performing two-dimensional image detection on the discharge box 200, it is possible to detect whether there is dirt and residual parts in the discharge box 200.

[0061] Optionally, the second intelligent visual detection component 8 includes a second bracket, a second camera component and two strip light source components 81, the second bracket is connected to the housing 1, the second camera component is fixed to the second bracket, the second camera component includes a second camera and a second lens, and the second lens is fixed to the second camera; the two strip light source components 81 are spaced and relatively arranged on the discharge conveying mechanism 6, and are located at the upper end of the discharge box 200. When the second camera component shoots the discharge box 200, by setting two strip light source components 81, the light coverage effect on the inner wall of the discharge box 200 is better, thereby improving the accuracy and efficiency of the detection. In this embodiment, the controller controls the coaxial light source component 422, the annular light source component 423 and the strip light source component 81 separately without affecting each other.

[0062] Further, the strip light source member 81 is arranged on the discharging conveying mechanism 6 in an adjustable position. Specifically, the discharging conveying mechanism 6 also includes an adjusting component 61, which includes a profile frame 611, an adjusting member 612, a first fastener and a second fastener. The profile frame 611 is fixed to the first support 201, the profile frame 611 is provided with a vertical groove 6111, and the bottom of the vertical groove 6111 is provided with connecting holes at vertical intervals, one end of the adjusting member 612 is provided with a transverse hole 6121, the first fastener penetrates the transverse hole 6121 and the vertical groove 6111 and is fixedly connected to the connecting hole, the other end of the adjusting member 612 is provided with an arc hole 6122, the strip light source member 81 is provided with a circular hole, and the second fastener penetrates the arc hole 6122 and is fixedly connected to the circular hole. With such a configuration, it is convenient to adjust the fill light angle of the strip light source member 81 to meet the actual fill light requirements.

[0063] In this embodiment, two arc-shaped holes 6122 are provided, and the two arc-shaped holes 6122 are distributed along the same circumferential direction. With such an arrangement, the rotation angle of the strip-shaped light source element 81 can be adjusted along the same rotation center.

The two positioning plates 522 are circumferentially arranged on the positioning platform 521. The two positioning plates 522 and the positioning platform 521 are combined to form a positioning cavity, and the workpiece is engaged with the positioning cavity. By providing the through-beam sensor 53, the grasping mechanism 3 can confirm whether the workpiece is placed on the positioning assembly 52 or has been taken away, so as to prevent the workpiece that has not been taken away from colliding with the workpiece that is placed again.

[0065] In this embodiment, if Figure 1 and Figure 2 As shown, the defect detection device also includes a detection status display 9, which is fixed to the casing 1 and is used to display the detection results of the workpiece.
