Description

Technical Field

[0001] The utility model relates to the technical field of packaging box detection, in particular to an intelligent detection device for the surface flatness of a packaging box. Background Art

[0002] As the name suggests, a packaging box is a box used to package products. With the rapid development of modern industry and the continuous improvement of people's living standards, the market demand for preformed packaging boxes, especially high-end preformed packaging boxes, has increased dramatically, which has also put forward higher requirements on the quality of preformed packaging boxes.

[0003] In the related art, a rectangular packaging box is designed, which has a total of 6 faces. During the production process, the surface flatness of the packaging box needs to be tested. Most of the related arts directly place the packaging box under the visual camera and use a high-resolution 3D industrial camera and related visual systems to test the flatness of the packaging box surface. However, different surfaces of the packaging box need to be tested during the inspection, so the packaging box needs to be turned over. Most of the related arts turn the packaging box over manually, which requires a lot of labor and has a low degree of automation, affecting the production and processing efficiency, and therefore needs to be improved.

[0007] When the packaging box is flat, the packaging box is placed at the highest end of the feeding rack. Due to the inclined setting of the feeding rack, the packaging box will slide on the feeding rack. When the packaging box is against the limit plate, the limit plate limits the packaging box, and the packaging box is above the abutment plate. At this time, the visual inspection instrument on the inspection rack performs flatness inspection on one side of the packaging box; after one side is inspected, the rotating component works, and the rotating component drives the rotating shaft to rotate so that the abutment plate is against the bottom of the packaging box. At the same time, the limit plate rotates, and the bending plate rotates a full 90 degrees, driving the packaging box to flip 90 degrees. After that, the packaging box can be separated from the limit plate and continue to slide on the feeding rack until it is limited by the next limit plate. This is repeated, and the limit detection of the packaging box by several bending plates and multiple flipping are carried out, so that the flatness of different surfaces of the packaging box can be detected, and the packaging box can be automatically turned over, which reduces manual labor and improves the degree of automation and production efficiency.

[0013] By adopting the above technical solution, the cylinder will reset after working, so that the limit plate remains perpendicular to the feed rack, and the abutment plate and the feed rack are flush with each other. After the cylinder is reset, the processor controls the visual inspection instrument to detect whether the positioning mark and the identification mark are flush. If the positioning mark and the identification mark are flush with each other, it is determined that the bending plate has been reset at this time.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses an intelligent detection device for the surface flatness of a packaging box. Figures 1 to 3 It includes a group of mounting frames 1 arranged in the vertical direction, and a group of feed frames 11 are symmetrically arranged on the inner side wall of the mounting frame 1. The feed frames 11 are fixedly arranged between the mounting frame 1, and the feed frames 11 are arranged at an angle. A number of bending plates 2 are arranged between the feed frames 11, and the bending plates 2 include abutment plates 21 and limit plates 22 that are perpendicular to each other. The abutment plates 21 are rotatably connected to the feed frames 11 through a rotating shaft 23, and the abutment plates 21 are flush with the feed frames 11. A number of detection frames 4 are also arranged on the mounting frame 1, and the number of the detection frames 4 corresponds to the number of the bending plates 2. The length direction of the detection frames 4 is perpendicular to the feed frames 11. A visual inspection instrument 41 is arranged on the detection frame 4, and the visual inspection instrument 41 is located directly above the bending plate 2. The shooting direction of the visual inspection instrument 41 is perpendicular to the plane of the feed frame 11. When testing the flatness of the packaging box, place the packaging box at the highest end of the feed rack 11. Since the feed rack 11 is tilted, the packaging box will slide on the feed rack 11. When the packaging box abuts against the limit plate 22, the limit plate 22 limits the position of the packaging box, and the packaging box is located above the abutment plate 21. At this time, the visual inspection instrument 41 on the inspection rack 4 is used to perform flatness inspection on one side of the packaging box.

[0032] Reference Figure 2 and Figure 3A rotating assembly 3 is provided on the mounting frame 1. The rotating assembly 3 includes a cylinder 31, a rack 32 and a gear 33. The cylinder 31 is fixed to the side wall of the mounting frame 1 by bolts. The rack 32 is connected to the piston rod of the cylinder 31. The gear 33 is provided at the end of the rotating shaft 23 and is coaxial with the rotating shaft 23. The gear 33 and the rack 32 are engaged with each other. After one side of the packaging box above the abutment plate 21 is detected, the piston rod of the cylinder 31 drives the rack 32 to slide, and the rack 32 is abutted against the gear 33, driving the gear 33 and the rotating shaft 23 to rotate, so that the abutment plate 21 is abutted against the bottom of the packaging box. At the same time, the limit plate 22 rotates, and the bending plate 2 rotates a full 90 degrees, driving the packaging box to flip 90 degrees, so that the limit plate 22 rotates to a position flush with the feed rack 11. After that, the packaging box can be separated from the limit plate 22 and continue to slide on the feed rack 11 until it is limited by the next limit plate 22. This is repeated, and the packaging box limit detection and multiple flipping are performed by several bending plates 2, so that the flatness of different surfaces of the packaging box can be detected.

[0033] Reference Figure 2 A pressure sensor 5 is provided on the side wall of the limit plate 22 facing the abutment plate 21. The pressure sensor 5 is connected to a processor. The cylinder 31 and the visual inspection instrument 41 are both connected to the processor signal. When the packaging box slides on the feeding rack 11 and abuts against the limit plate 22, the pressure sensor 5 detects the pressure value. At this time, the processor controls the visual inspection instrument 41 to work immediately to detect the flatness of the top surface of the packaging box, and controls the cylinder 31 to delay work, automatically controls the visual inspection instrument 41 to work, and automatically turns the packaging box over for transportation after detection, further improving the degree of automation of the detection work.

[0034] Reference Figure 1 , a positioning mark is provided on the abutment plate 21, and an identification mark is provided on the feed rack 11. When the limit plate 22 and the feed rack 11 are perpendicular to each other, the positioning mark and the identification mark are flush with each other, and the cylinder 31 works to reset the package box after it is turned over, so that the limit plate 22 remains perpendicular to the feed rack 11, and the abutment plate 21 and the feed rack 11 are flush with each other. At this time, the processor controls the visual inspection instrument 41 to work and detect whether the positioning mark and the identification mark are flush with each other. If the positioning mark and the identification mark are flush with each other, it is determined that the bending plate 2 has been reset at this time. If the positioning mark and the identification mark are not flush, the alarm is controlled to work, which serves as a reminder when the bending plate 2 is not reset correctly.

[0035] Reference Figure 1 and Figure 3 A group of guide plates 7 are symmetrically arranged between the mounting frames 1. The guide plates 7 are located above the feed rack 11. The length direction of the guide plates 7 is arranged along the length direction of the feed rack 11. When the packaging box slides or turns over on the feed rack 11, the guide plates 7 guide and limit the packaging box to reduce the phenomenon of packaging box deviation.

[0036] Reference Figure 3 Guide rods 71 are provided at both ends of the guide plate 7. The guide rods 71 pass through the mounting frame 1 and are slidably connected to the mounting frame 1. Scale lines are provided on the surface of the guide rods 71. A screw 72 is provided on the side of the guide plate 7 that rotates toward the mounting frame 1. The screw 72 passes through the mounting frame 1 and is threadedly connected to the mounting frame 1. A handle 721 is provided on the end of the screw 72 that is away from the guide plate 7. Gripping the handle 721 drives the screw 72 to rotate, while the guide rods 71 guide the guide plate 7, which can drive the guide plate 7 to slide between the mounting frame 1, adjust the distance between the two guide plates 7, and facilitate the guide plate 7 to limit and guide packaging boxes of different widths, thereby expanding the applicability of the device. A clamping plate 8 is fixedly provided at one end of the guide rod 71 away from the guide plate 7, and a clamping spring 81 is sleeved on the guide rod 71. One end of the clamping spring 81 is pressed against the outer wall of the mounting frame 1, and the other end of the clamping spring 81 is pressed against the clamping plate 8; the clamping spring 81 is continuously pressed against the clamping plate 8, and the guide plate 7 is continuously subjected to a pulling force toward the mounting frame 1, which is beneficial to improving the stability of the guide plate 7 between the mounting frames 1.

[0037] The implementation principle of the intelligent detection device for the surface flatness of a packaging box in the embodiment of the present application is as follows: when detecting the flatness of a packaging box, the packaging box is placed at the highest end of the feeding rack 11. Since the feeding rack 11 is tilted, the packaging box will slide on the feeding rack 11. When the packaging box abuts against the limiting plate 22, the limiting plate 22 limits the packaging box. The packaging box is located above the abutting plate 21. At this time, the visual inspection instrument 41 on the inspection rack 4 is used to perform a flatness inspection on one side of the packaging box. After the inspection, the piston rod of the cylinder 31 drives the rack 32 to slide, and the rack 32 abuts against the gear 33, driving the gear 33 and the rotating shaft 23 to rotate, so that the abutting plate 21 is against the bottom of the packaging box, and at the same time the limit plate 22 rotates, the bending plate 2 rotates a whole 90 degrees, driving the packaging box to turn over 90 degrees, so that the limit plate 22 rotates to a position flush with the feed rack 11. After that, the packaging box can be separated from the limit plate 22 and continue to slide on the feed rack 11 until it is limited by the next limit plate 22. This is repeated, and the packaging box is limited and turned over and tested multiple times by several bending plates 2, so that the flatness of different surfaces of the packaging box can be tested. The whole process does not require manual operation, and the packaging box is automatically turned over, which reduces human labor and improves the degree of automation of the device and production and processing efficiency.
