Description

Technical Field

[0001] The present invention relates to the field of packing box sorting and conveying devices, and particularly to a sorting and conveying device and method for packing box production and preparation based on industrial vision. Background Technique

[0002] A packing box, as the name implies, is a box used for packing products, usually made of paper, plastic, metal, wood or other synthetic materials. After agricultural products are produced, in order to make the agricultural products easy to transport and store, prefabricated packages are commonly used to pack the agricultural products. It not only physically protects the agricultural products from damage, but also plays an important role at multiple levels. During the production process of packing boxes, it is necessary to detect the surface defects thereof, and sort out the qualified products and unqualified products among them, so as to avoid damage to agricultural products when unqualified packing boxes are used to pack agricultural products. A common detection method is to use a camera to collect the surface image of the packing box, and then send the image to the background control terminal for image recognition and analysis.

[0003] The existing detection of packing boxes usually detects the outer side surface thereof, but ignores the detection of the inner side surface of the packing box. If an additional internal detection mechanism is set up separately, it will not only make the detection device structure more complex, but also cause waste of resources. Therefore, how to develop a sorting and conveying device that can detect both the internal defects and the external defects of the packing box has become a difficult problem to be solved urgently at present.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As mentioned in the background art of the present application, through research, it is found that the existing detection of the packaging box 47 usually detects its outer side, but ignores the detection of the inner side of the packaging box 47. If an additional internal detection mechanism is set up separately, not only will the structure of the detection device become more complex, but also resource waste will be caused. Therefore, how to develop a sorting and conveying device that can detect both the internal defects and the external defects of the packaging box 47 has become a difficult problem that needs to be solved urgently at present.

[0042] To solve the above defects, the present application discloses a sorting and conveying device and method for the production and preparation of packaging boxes based on industrial vision. Through the internal and external detection components provided, both the internal defects and the external defects of the packaging box 47 can be detected.

[0043] The following will introduce in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0044] Please refer to Figures 1 to 10, in the embodiment of the present invention, a sorting and conveying device for the production and preparation of packaging boxes based on industrial vision includes a first roller conveyor line 1. On both sides of the top surface of the first roller conveyor line 1, side plates 2 are fixedly connected. One end of the first roller conveyor line 1 is connected to a transfer table 3. A second roller conveyor line 4 is provided on one side of the transfer table 3, and a third roller conveyor line 5 is provided on the other side of the transfer table 3. Linear guides 6 are symmetrically and fixedly connected to both sides of the first roller conveyor line 1, and linear motors 7 are movably connected to the outer sides of the linear guides 6. A concave frame 8 is fixedly connected between the two linear motors 7, and an internal and external detection component is provided in the groove of the concave frame 8. An angle adjustment mechanism is provided on one side inside the first roller conveyor line 1, and push-centering mechanisms are symmetrically provided on both sides of the angle adjustment mechanism. Two parallel limiting mechanisms are provided on the other side inside the first roller conveyor line 1, and a bottom detection mechanism is provided between the two limiting mechanisms. In this application, through the provided internal and external detection components, both internal defects and external defects of the packaging box 47 can be detected. In addition, the internal and external detection components, in combination with the linear guide 6 and the linear motor 7, can perform follow-up detection during the forward movement of the packaging box 47, thereby improving the detection efficiency.

[0045] In this embodiment, the internal and external detection components specifically include: a top support plate 9 fixed inside the groove of the concave frame 8, a driving cavity 11 is opened in the inner center of the top support plate 9, and a transmission gear plate 12 is rotatably connected inside the driving cavity 11, a driving motor 10 is fixedly connected to the center of the top surface of the top support plate 9, and the bottom output shaft of the driving motor 10 passes through the driving cavity 11 and is fixedly connected to the transmission gear plate 12, four rectangular grooves 13 distributed in a cross are opened on the bottom end surface of the top support plate 9, and a transverse lead screw 14 is rotatably connected inside the rectangular groove 13, one end of the transverse lead screw 14 passes through the driving cavity 11 and is fixedly connected to a transmission gear 15, and the transmission gear 15 is connected to the transmission gear 15. The toothed discs 12 are meshed with each other, and a moving block 16 matching with it is movably connected inside the rectangular groove 13, and a threaded hole 17 for the transverse lead screw 14 to pass through is opened on the side of the moving block 16, and a vertical plate 18 is fixedly connected to the bottom end face of the moving block 16, and a vertical hole 19 is opened inside the vertical plate 18, and a first through-type stepping motor 21 is embedded in the bottom end of the vertical hole 19, and a first through-type stepping screw 20 is transmission-connected inside the first through-type stepping motor 21, and a lifting plate 24 is fixedly connected to the bottom end of the first through-type stepping screw 20, and a first camera 25 is embedded in the outer side surface, inner side surface and bottom end surface of the lifting plate 24, and a limiter is provided between the lifting plate 24 and the corresponding vertical plate 18. 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.

[0046] In this embodiment, the limiting member specifically includes: limiting shaft holes 22 opened on both sides of the vertical hole 19, the limiting shaft holes 22 are movably connected with the limiting optical axis 23, and the bottom end of the limiting optical axis 23 is fixedly connected to the corresponding lifting plate 24. The setting of the limiting member can improve the stability of the lifting plate 24 during the up and down lifting process.

[0047] In this embodiment, the angle adjustment mechanism specifically includes: a concave support plate 28 fixed to one side of the bottom end surface of the first roller conveyor line 1. A strip-shaped plate 29 is movably connected inside the groove of the concave support plate 28. A second through-type stepping motor 30 is fixedly connected to the middle position of the bottom end surface of the concave support plate 28. A second through-type stepping lead screw 31 is movably connected inside the second through-type stepping motor 30. The top end of the second through-type stepping lead screw 31 penetrates through the concave support plate 28 and is fixedly connected to the strip-shaped plate 29.

The top output shaft of the rotary motor 35 penetrates through the motor support plate 34 and is fixedly connected to an angle rotation plate 36. Through the provided angle adjustment mechanism in this application, the angle of the packaging box 47 can be adjusted in advance to align the angle of the packaging box 47 with the advancing direction, thereby saving the working difficulty of the subsequent pushing and centering mechanism. In the traditional pushing and centering, it directly pushes and centers from both sides of the packaging box 47. For a packaging box 47 with a relatively severe inclination, the traditional pushing and centering is prone to uneven force, which easily damages the packaging box 47. However, the angle adjustment mechanism and the pushing and centering mechanism in this application cooperate with each other to eliminate this defect and effectively avoid damage to the packaging box 47.

[0048] In this embodiment, the pushing and centering mechanism specifically includes: a placement groove 45 opened on the inner side surface of the side plate 2. A rectangular push plate 46 is movably connected inside the placement groove 45. A telescopic motor 44 is fixedly connected to the position on the outer side surface of the side plate 2 corresponding to the placement groove 45. The output shaft of the telescopic motor 44 penetrates through the side plate 2 and is fixedly connected to the rectangular push plate 46. The pushing and centering mechanism can cooperate with the angle adjustment mechanism to avoid damaging the packaging box 47 while pushing and centering the packaging box 47.

[0049] In this embodiment, the limiting mechanism specifically includes: a first strip-shaped support plate 26 fixed to the bottom end surface of the first roller conveyor line 1. Two juxtaposed cylinders 27 are fixedly connected to the top end surface of the first strip-shaped support plate 26. The top output shafts of the cylinders 27 can extend out from the gaps between the rollers of the first roller conveyor line 1. The limiting mechanism can block the packaging box 47 on the first roller conveyor line 1.

[0050] In this embodiment, the bottom detection mechanism specifically includes: a second strip-shaped support plate 37 fixed to 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-shaped support plate 37. Fill lights 39 are embedded on both sides of the second camera 38. The second strip-shaped support plate 37 is located below the gaps between the rollers of the first roller conveyor line 1. The bottom detection mechanism can detect the bottom end surface of the packaging box 47.

[0051] 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.

[0052] 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:

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] After the detection is completed, the packaging box 47 is sent to the transfer table 3 by the first roller conveyor line 1. The longitudinal conveyor wheels 43 on the transfer table 3 run to continue conveying the packaging box 47 forward until the packaging box 47 contacts the guiding roller 41. If the packaging box 47 is detected as qualified, the transfer table 3 sends the packaging box 47 to the second roller conveyor line 4 through the transverse conveyor wheels 42. If the packaging box 47 is detected as unqualified, the transfer table 3 sends the packaging box 47 to the third roller conveyor line 5 through the transverse conveyor wheels 42. During the process, the guiding roller 41 plays a guiding role for the packaging box 47. It should be noted that both the transverse conveyor wheels 42 and the longitudinal conveyor wheels 43 are driven by independent micro motors.

[0060] Through the internal and external detection components provided in the present invention, both the internal defects of the packaging box 47 and the external defects of the packaging box 47 can be detected. In addition, the internal and external detection components are paired with the linear guide rail 6 and the linear motor 7 to follow the detection during the forward movement of the packaging box 47, thereby improving the detection efficiency. Through the provided angle adjustment mechanism, the angle of the packaging box 47 can be adjusted in advance to align the angle of the packaging box 47 with the forward direction, thereby saving the working difficulty of the subsequent pushing and centering mechanism. The traditional pushing and centering directly pushes and centers from both sides of the packaging box 47. For the packaging box 47 with a relatively severe inclination, the traditional pushing and centering is uneven in force and easily causes damage to the packaging box 47. However, the angle adjustment mechanism and the pushing and centering mechanism of the present application cooperate with each other to eliminate this defect and effectively avoid damage to the packaging box 47.

[0061] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.

[0062] The above-mentioned are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
