[0011] The detection component includes an image acquisition camera 1 and an image acquisition device 2. The top outer wall of the frame is fixed with a gantry 1 by bolts. The image acquisition camera 1 is fixed to the top lower surface of the gantry 1, and the image acquisition device 2 is fixed to the bottom inner wall of the frame by bolts.

[0015] A better solution in the above solution is: a multi-protrusion cam is fixed to the outer wall of the other roller shaft through a connecting shaft, and the pressing end of the control switch 1 is in contact with the multi-protrusion cam.

[0016] As a further solution of the present invention: the control switch 1 cooperates with the shutter control of the image collector 2, and the control switch 2 cooperates with the shutter control of the image acquisition camera 1.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0039] 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 having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Embodiment 1:

[0041] An intelligent prefabricated component quality detection device, such as Figure 1-Figure 7As shown, it includes a conveying mechanism 1 fixed to the ground by a leg group 4, a detection component 3 arranged on the conveying mechanism 1 and located in the middle of the conveying mechanism 1, and two groups of shading components 2 arranged above the conveying mechanism 1 and located on both sides of the detection component 3.

[0042] The conveying mechanism 1 includes a frame 5 and a plurality of conveying rollers 10 rotatably connected to the inner side of the frame 5 via a roller shaft 6. The outer wall of the roller shaft 6 is connected to a pulley 7 via a key. Two adjacent pulleys 7 are coupled via a synchronous belt 8. A motor 9 is fixed to the outer wall of one side of the frame 5 via bolts. The output shaft of the motor 9 is connected to the end of one of the roller shafts 6 via a coupling.

[0043] The detection component 3 includes an image acquisition camera 12 and an image acquisition device 2 15. The top outer wall of the frame 5 is fixed with a gantry 11 by bolts. The image acquisition camera 12 is fixed to the top lower surface of the gantry 11, and the image acquisition device 2 15 is fixed to the bottom inner wall of the frame 5 by bolts.

[0044] When the device is in use, the prefabricated component can be placed on the top of the conveying mechanism 1, and then the motor 9 is started. The motor 9 drives the roller 6 to rotate, thereby driving all the rollers 6 to rotate through the pulley 7, so as to convey the prefabricated component. When it is conveyed between the image acquisition camera 12 and the image acquisition device 2 15, the image acquisition camera 12 and the image acquisition device 2 15 are started to take pictures, thereby realizing image acquisition, and then the acquired image is analyzed to perform appearance quality inspection.

[0045] The image acquisition camera 12 and the image acquisition device 2 15 both take images intermittently. After the imaging is completed, the multiple images taken intermittently are stitched together in sequence to form a complete image. Then, a standard image of a defect-free component is prepared in advance, and the collected complete image is compared with the standard image for quality analysis and detection.

[0046] This device, by setting up a conveying mechanism 1, an image acquisition camera 12 and an image acquisition device 2 15, adopts a linear conveying plus intermittent imaging form to acquire images, and then the images after intermittent imaging can be spliced ​​to form a complete image of the component, and then compared, thereby realizing automatic quality inspection of prefabricated components. Compared with manual inspection, it increases accuracy and efficiency.

[0047] In order to solve the problem of image acquisition clarity; Figure 3 , 7 As shown, the detection component 3 also includes a fill light 13 and a fill light 14 . The fill light 13 is fixed to the side wall of the image acquisition camera 12 , and the fill light 14 is fixed to the side wall of the image acquisition device 2 15 .

[0048] The shading assembly 2 includes a gantry 33 and a plurality of shading strips 32 . The gantry 33 is fixed to the top outer wall of the frame 5 by bolts, and the tops of the plurality of shading strips 32 are fixed to one side of the top lower surface of the gantry 33 .

[0049] In order to prevent the uncontrollable intensity of external light from affecting image acquisition, the two sides of the detection component 3 are shielded by the shading component 2, and the internal light is insufficient:

[0050] The device is provided with a shielding strip 32 which can shield external light, and uses fill light 13 and fill light 2 14 for fill light, thereby preventing the influence of external light intensity on image acquisition on the one hand, and also allowing no fill light to be performed on the other hand, thereby increasing the clarity of image acquisition.

[0051] In order to solve the problem of matching image acquisition frequency with conveying speed; Figure 4 As shown, a control switch 16 is fixed to the side wall of the frame 5, and a control switch 20 is fixed to the side wall of the gantry frame 11. The side wall of one of the roller shafts 6 is connected to a transition shaft 22 through a transmission assembly 21. The transition shaft 22 is rotatably connected to the side wall of the frame 5, and a single protruding cam 19 is fixed to the outer wall of the transition shaft 22. The pressing end of the control switch 20 is in contact with the single protruding cam 19.

[0052] A multi-protrusion cam 17 is fixed to the outer wall of the other roller shaft 6 via a connecting shaft 18 , and the pressing end of the control switch 16 contacts and cooperates with the multi-protrusion cam 17 .

[0053] The control switch 16 cooperates with the shutter control of the image acquisition device 2 15 , and the control switch 2 20 cooperates with the shutter control of the image acquisition camera 1 12 .

[0054] During the conveying process, since the image acquisition camera 12 and the viewing area are limited, when it takes images intermittently, if the interval of intermittent imaging is large, it will cause incomplete imaging. If the interval is small, the overall imaging range is large, which increases the difficulty of post-cutting processing. At the same time, since the image acquisition device 2 15 is located below the conveying roller 10, it can only take images through the gap of the conveying roller 10. If there is an error in the imaging interval, it will also cause the same problem as the image acquisition camera 12. Based on this:

[0055] During the conveying process, the roller 6 will rotate, thereby driving the transition shaft 22 and the single-protrusion cam 19 to rotate through the transmission component 21 on the one hand, and driving the multi-protrusion cam 17 to rotate through the connecting shaft 18 on the other hand. When the control switch 16 and the multi-protrusion cam 17 rotate, when the protrusions limit the control switch 20 and the control switch 1 16 respectively, they will squeeze the pressing ends of the control switch 20 and the control switch 1 16, thereby generating an electrical signal, which is then used to control the image acquisition camera 12 and the image acquisition device 2 15 to start taking pictures.

[0056] The device, by setting a control switch 16 and a control switch 20, can respectively control the image collector 2 15 and the image acquisition camera 12 to start taking pictures, and then through the cooperation of the control switch 16 and the control switch 20 with the multi-protrusion cam 17 and the single-protrusion cam 19, the shooting interval and the conveying speed of the image collector 2 15 and the image acquisition camera 12 can be matched with each other, thereby ensuring the integrity of intermittent imaging while preventing the processing difficulties caused by taking too many images.

[0057] In order to solve the problem of adjusting the imaging range and the time interval of intermittent imaging; Figure 5 As shown, the transmission assembly 21 includes a cone wheel 1 25 and a cone wheel 2 31. The cone wheel 1 25 is fixed to the end of the roller shaft 6, and the cone wheel 2 31 is fixed to the outer wall of the transition shaft 22. The outer walls of the cone wheel 1 25 and the cone wheel 2 31 are transmitted by the same transmission rope 30.

[0058] When the roller shaft 6 rotates, it drives the cone wheel 1 25 to rotate, thereby driving the cone wheel 2 31 to rotate through the transmission rope 30, thereby driving the transition shaft 22 to rotate.

[0059] The transmission assembly 21 also includes two limiting wheels 26 respectively matched with the two sides of the transmission rope 30, the inner wall of the limiting wheel 26 is rotatably connected to the limiting shaft frame 27, the side wall of the frame 5 is fixed with a bracket 29 by bolts, the inner wall of the bracket 29 is provided with a guide groove 28, and the limiting shaft frame 27 is movably matched with the inner wall of the guide groove 28.

[0060] The end of the bracket 29 is fixed with the second motor 24 by bolts, the output shaft of the second motor 24 is fixed with the screw rod 23 by a coupling, and the screw rod 23 is connected to the inner wall of the limiting shaft frame 27 by threads.

[0061] Since the different imaging ranges of the image acquisition camera 12 require a matching relationship between the imaging interval of the image acquisition camera 12 and the conveying speed, when the motor 24 is started, it can drive the screw 23 to rotate, thereby moving the limiting shaft frame 27. The movement of the limiting shaft frame 27 will drive the transmission rope 30 to move through the limiting wheel 26, thereby changing the matching position of the transmission rope 30 and the cone wheel 1 25 and the cone wheel 2 31, thereby changing the transmission ratio of the cone wheel 1 25 and the cone wheel 2 31.

[0062] The device, by setting a transmission component 21, can change the transmission ratio of the cone wheel 25 and the cone wheel 31 by changing the position of the transmission rope 30, thereby changing the matching correlation ratio between the conveying speed and the interval time of the image acquisition camera 12, so that targeted adjustment can be made according to the unused viewing range of the image acquisition camera 12.

[0063] When the present embodiment is in use, the prefabricated component can be placed on the top of the conveying mechanism 1, and then the motor 9 is started, the motor 9 drives the roller 6 to rotate, and then drives all the rollers 6 to rotate through the pulley 7, so as to convey the prefabricated component. When it is conveyed between the image acquisition camera 12 and the image acquisition device 2 15, the image acquisition camera 12 and the image acquisition device 2 15 are started to take pictures, so as to realize image acquisition, and then the acquired images are analyzed to perform appearance quality inspection; the image acquisition camera 12 and the image acquisition device 2 15 are both intermittent image acquisition. After the image acquisition is completed, the multiple images taken intermittently are spliced ​​in sequence to form a complete image, and then Then prepare a standard image of the component without defects in advance, compare the collected complete image with the standard image, and conduct quality analysis and detection. In order to prevent the uncontrollable influence of the intensity of external light on image acquisition, the two sides of the detection component 3 are shielded by the shading component 2. Insufficient internal light: This device is provided with a shading strip 32 in the form of a shielding, which can block the external light, and at the same time, the fill light 13 and the fill light 2 14 are used for fill light, so as to prevent the influence of the intensity of external light on image acquisition on the one hand, and on the other hand, it can also be performed without fill light, thereby increasing the clarity of image acquisition. During the transportation process, since the image acquisition camera 12 and the framing area are limited, when it takes images intermittently, If the interval of intermittent imaging is large, it will cause incomplete imaging. If the interval is small, the overall imaging range will be large, increasing the difficulty of later cutting and processing. At the same time, since the image collector 15 is located below the conveying roller 10, it can only capture images through the gap of the conveying roller 10. If there is an error in the imaging interval, it will also cause the same problem as the image acquisition camera 12. Based on this: during the conveying process, the roller 6 will rotate, thereby on the one hand driving the transition shaft 22 and the single-protrusion cam 19 to rotate through the transmission component 21, and on the other hand driving the multi-protrusion cam 17 to rotate through the connecting shaft 18. When the control switch 16 and the multi-protrusion cam 17 rotate, when the protrusions limit the control switch 20 and the control switch 16 respectively, the protrusions will be moved. When the switch 16 is closed, the control switch 20 and the pressing end of the control switch 16 will be squeezed to generate an electrical signal, which is then used to control the image acquisition camera 12 and the image acquisition device 2 15 to start taking pictures. At the same time, due to the different imaging ranges of the image acquisition camera 12, a matching relationship between the imaging interval of the image acquisition camera 12 and the conveying speed is required. When the motor 24 is started, it can drive the screw 23 to rotate, thereby moving the limit shaft frame 27. The movement of the limit shaft frame 27 will drive the transmission rope 30 to move through the limit wheel 26, thereby changing the matching position of the transmission rope 30 with the cone wheel 1 25 and the cone wheel 2 31, so that the transmission ratio of the cone wheel 1 25 and the cone wheel 2 31 changes.
