The internal and external detection components have two working modes. The first working mode is: the four lifting plates 24 are spread out and distributed around the packaging box 47, and the first camera 25 on the inner side of the lifting plate 24 is used to detect the outer side of the packaging box 47; the second working mode is: the four lifting plates 24 are gathered together to form a rectangle and extend into the interior of the packaging box 47, and the inner side of the packaging box 47 is detected by the first camera 25 on the outer side of the lifting plate 24, and the bottom end surface of the packaging box 47 is detected by the first camera 25 on the bottom end surface of the lifting plate 24.

The angle adjustment mechanism set up in the present application can pre-adjust the angle of the packaging box 47 so that the angle of the packaging box 47 is aligned with the forward direction, thereby saving the difficulty of the subsequent pushing and centering mechanism. The traditional pushing and centering mechanism directly pushes the packaging box 47 from both sides. For the packaging box 47 with a serious tilt, the uneven force of the traditional pushing and centering mechanism can easily cause damage to the packaging box 47.

[0029] In this embodiment, the limiting mechanism specifically includes: a first strip support plate 26 fixed on the bottom end surface of the first roller conveyor line 1, and two parallel cylinders 27 are fixedly connected to the top end surface of the first strip support plate 26, and the top output shaft of the cylinder 27 can extend from the roller gap of the first roller conveyor line 1. The limiting mechanism can stop the packaging box 47 on the first roller conveyor line 1.

[0030] In this embodiment, the bottom detection mechanism specifically includes: a second strip support plate 37 fixed on the bottom end surface of the first roller conveyor line 1, a second camera 38 is embedded in the center of the top end surface of the second strip support plate 37, and fill lights 39 are embedded on both sides of the second camera 38, and the second strip support plate 37 is located below the roller gap of the first roller conveyor line 1.

[0031] In this embodiment, a plurality of groups of movable transverse conveying wheels 42 and longitudinal conveying wheels 43 are embedded in the top surface of the transfer platform 3, and the plurality of groups of transverse conveying wheels 42 and longitudinal conveying wheels 43 are alternately arranged, and the number of each group of transverse conveying wheels 42 and longitudinal conveying wheels 43 is several. A guide plate 40 is fixedly connected to one side of the top surface of the transfer platform 3, and a plurality of movable guide rollers 41 are embedded in one side of the guide plate 40. The transfer platform 3 can guide the qualified products and the unqualified products to different roller conveyor lines respectively.

[0032] The present application also discloses a sorting and conveying method for packaging box production and preparation based on industrial vision, which uses a sorting and conveying device for packaging box production and preparation based on industrial vision, and includes the following steps: The packaging box 47 to be sorted is placed on the first roller conveyor line 1, and the first roller conveyor line 1 drives the packaging box 47 to move forward.

[0033] The limit mechanism on the left side stops the packaging box 47, and the internal and external detection components collect the image of the packaging box 47 below through the first camera 25 on the bottom surface of the lifting plate 24, and send the image to the external background control terminal for analysis, and analyze the inclination angle of the packaging box 47 and the corresponding angle parameters that need to be adjusted. Among them, the operation process of the limit mechanism is that the cylinder 27 runs to extend its output shaft from the roller gap of the first roller conveyor line 1, and the extended output shaft of the cylinder 27 blocks the forward direction of the packaging box 47.

[0034] The angle adjustment mechanism adjusts the angle of the packaging box 47 according to the angle parameters in the analysis results, and then the push-centering calibration mechanism pushes the packaging box 47. The operation process of the angle adjustment mechanism is that when the packaging box 47 is stopped by the limit mechanism on the left, the packaging box 47 is located above the angle adjustment mechanism. At this time, the second through-type stepper motor 30 is running, and the second through-type stepper screw 31 slowly rises. During the process, the strip plate 29 follows the rise, and the linear bearing 32 and the vertical optical axis 33 are relatively displaced. The angle rotating plate 36 supports the packaging box 47 and follows the rise. Then, the rotating motor 35 runs and drives the angle rotating plate 36 to rotate synchronously with the packaging box 47 according to the angle parameters, thereby adjusting the forward angle of the packaging box 47. The operation process of the push-centering calibration mechanism is that the telescopic motor 44 runs to extend the output shaft, driving the rectangular push plate 46 to extend from the placement slot 45, and the two rectangular push plates 46 approach each other from both sides of the packaging box 47, so that the packaging box 47 is located in the middle position.

[0035] The limit mechanism on the left allows the packaging box 47 to pass, and the internal and external detection components follow and detect the outer side of the packaging box 47. At this time, the internal and external detection components are in the first working mode, that is, the four lifting plates 24 are spread out and distributed around the packaging box 47. During the following detection process, the packaging box 47 continues to move forward on the first roller conveyor line 1, and the entire internal and external detection component follows and moves synchronously with the linear guide 6 and the linear motor 7, so that the external detection can be completed during the movement of the packaging box 47. The first through-type stepper motor 21 is running, and under the limitation of the limit shaft hole 22 and the limit optical axis 23, the first through-type stepper screw 20 descends along the vertical hole 19, and the lifting plate 24 follows the descent, and the first camera 25 on the inner side of the lifting plate 24 detects the outer side of the packaging box 47, and then performs all-round detection of the outer side of the packaging box 47 at various heights.

[0036] The bottom detection mechanism detects the bottom surface of the packaging box 47, and then the limit mechanism on the right side stops the packaging box 47. The operation process of the bottom detection mechanism is that the second camera 38 detects the bottom surface of the packaging box 47 passing above, and during the process, the fill light 39 performs fill light to make the collected image clearer.

[0037] The internal and external detection components switch their working mode and extend into the interior of the packaging box 47 . The limiting mechanism on the right side allows the packaging box 47 to pass through, and the internal and external detection components follow and detect the inner side of the packaging box 47 . At this time, the internal and external detection components are switched from the first working mode to the second working mode. The switching process is that each lifting plate 24 is first raised to the top through the first through-type stepper motor 21 and the first through-type stepper screw 20. Then, the driving motor 10 drives the transmission gear plate 12 to rotate, and then drives the transmission gear 15 meshing with the transmission gear plate 12 to rotate, and the transverse screw 14 follows the rotation. During the process, the moving block 16 moves along the transverse screw 14 in the rectangular groove 13 toward the driving cavity 11 until the four lifting plates 24 gather together to form a rectangle. Then, the first through-type stepper motor 21 and the first through-type stepper screw 20 are used to synchronously lower each lifting plate 24, so that the four lifting plates 24 enter the interior of the packaging box 47, and the first camera 25 on the outer side of the lifting plate 24 detects the inner side of the packaging box 47, and the first camera 25 on the bottom end face of the lifting plate 24 detects the bottom end face of the packaging box 47.

[0038] After the inspection is completed, the packaging box 47 is sent to the transfer platform 3 by the first roller conveyor line 1, and the longitudinal conveying wheel 43 on the transfer platform 3 runs to continue to convey the packaging box 47 forward until the packaging box 47 contacts the guide roller 41. If the packaging box 47 is detected as qualified, the transfer platform 3 sends the packaging box 47 to the second roller conveyor line 4 through the transverse conveying wheel 42. If the packaging box 47 is detected as unqualified, the transfer platform 3 sends the packaging box 47 to the third roller conveyor line 5 through the transverse conveying wheel 42. During the process, the guide roller 41 guides the packaging box 47. It should be noted that the transverse conveying wheel 42 and the longitudinal conveying wheel 43 are driven and operated by independent micro motors.

[0039] The present invention can detect both internal defects and external defects of the packaging box 47 by setting up internal and external detection components. In addition, the internal and external detection components can be matched with the linear guide 6 and the linear motor 7 to follow the detection during the forward movement of the packaging box 47, thereby improving the detection efficiency. The angle of the packaging box 47 can be adjusted in advance by the angle adjustment mechanism, so that the angle of the packaging box 47 is aligned with the forward direction, thereby saving the difficulty of the subsequent push-centering calibration mechanism. The traditional push-centering calibration is directly pushed from both sides of the packaging box 47. For a packaging box 47 with a serious tilt, the uneven force of the traditional push-centering calibration is easy to cause the packaging box 47 to be damaged. The angle adjustment mechanism of the present application cooperates with the push-centering calibration mechanism to eliminate this defect and effectively avoid damage to the packaging box 47.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
