Description

Technical Field

[0001] This utility model relates to the field of box inspection technology, and in particular to a box six-sided inspection device. Background Technology

[0002] Some six-sided boxes, such as pharmaceutical product packaging boxes, have barcode labels affixed to all six sides during the production process. Before the final packing and warehousing stage, it is necessary to check whether the barcode labels on all six sides are complete and correct.

[0003] In current technologies, small-batch production involves manual scanning of each barcode using a barcode scanner. However, manual inspection can lead to fatigue over extended periods, and defective products can disrupt production and generate customer complaints. Manual inspection alone cannot completely eliminate this risk. For large-batch production, inspection equipment is typically required to check all six sides of the box. However, current logo inspection equipment sometimes only reads barcodes on the sides of the box, and sometimes only on the back, failing to simultaneously verify barcodes on all six sides, resulting in low inspection efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a six-sided box inspection device that can inspect labels on all six sides of the box with high inspection efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A six-sided inspection device for a box is used to inspect labels on six sides of a box. The six-sided inspection device includes:

[0007] An adsorption device is configured to grasp the box to the detection station and drive the box to rotate.

[0008] A first camera module is disposed above the box body and is configured to acquire an image of the top surface of the box body;

[0009] The second camera module is located below the box body and is configured to acquire an image of the bottom surface of the box body;

[0010] A third camera module is disposed on the side of the box body. The third camera module is configured to sequentially acquire images of the first side, second side, third side, and fourth side of the box body during the process of the adsorption device driving the box body to rotate.

[0011] The host computer is connected to the first camera module, the second camera module, and the third camera module via communication.

[0012] Furthermore, the adsorption device includes a triaxial module, a rotating mechanism, and an adsorption mechanism. The triaxial module is configured to drive the adsorption mechanism to move in the XYZ space, the rotating mechanism is configured to drive the adsorption mechanism to rotate, and the adsorption mechanism is configured to adsorb the top surface.

[0013] Furthermore, the adsorption mechanism includes a vacuum disk and a plurality of suction cups disposed on the vacuum disk. The vacuum disk has an adsorption channel, which is connected to a vacuum generator, and the vacuum suction cups are in communication with the adsorption channel.

[0014] Furthermore, the first camera module is disposed on the side of the vacuum disk away from the vacuum suction cup, and a camera hole is formed on the vacuum disk to avoid the first camera of the first camera module.

[0015] Furthermore, the adsorption mechanism also includes a connecting plate, a floating rod, an elastic element, and a fixing block. The connecting plate is connected to the rotating mechanism. One end of the floating rod is fixedly connected to the vacuum disk, and the other end is slidably connected to the connecting plate. The fixing block is sleeved and fixed on the floating rod. The elastic element is sleeved on the floating rod, with one end abutting against the connecting plate and the other end abutting against the fixing block.

[0016] Furthermore, the adsorption mechanism also includes a limiting bolt, which is disposed on the fixed block on the side near the connecting plate.

[0017] Furthermore, the six-sided box inspection equipment also includes a first conveying device and a second conveying device. The first conveying device is configured to transport the box to the inspection station, and the second conveying device is configured to transport the box to the next production process. The first conveying device and the second conveying device are arranged in parallel, and there is a gap between the first conveying device and the second conveying device to avoid the second camera of the second camera module.

[0018] Furthermore, the first conveying device includes a first conveyor belt and a limiting rod, the limiting rod being disposed at the end of the first conveyor belt near the gap, and the limiting rod being located above the first conveyor belt.

[0019] Furthermore, the rotating mechanism is a side-axis hollow rotating platform, with the fixed end of the rotating mechanism fixedly connected to the output end of the three-axis module, and the rotating end of the rotating mechanism fixedly connected to the connecting plate.

[0020] Furthermore, the six-sided detection device for the box also includes a two-axis module, which is configured to drive the third camera module to move in the YZ plane.

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] 1. By setting up an adsorption device, the box can be adsorbed and transported to the inspection station, and the box can be driven to rotate at the inspection station. This allows the box to be captured by only three camera modules on the top, bottom and sides, which greatly reduces the production and maintenance costs of the equipment.

[0023] 2. By setting up an adsorption mechanism powered by suction cups, the adsorption mechanism can be adapted to boxes of different sizes. At the same time, the third camera module on the side is also set on the two-axis module, which enables this device to detect boxes of different sizes, making it widely applicable.

[0024] 3. By mounting the first camera module on the adsorption mechanism, the vertical installation space required for the device is significantly reduced, thus shrinking its size. Simultaneously, the first camera module can move with the adsorption mechanism, greatly expanding the device's applicability and enabling it to accommodate boxes of more sizes.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figures 1 to 7 As shown in the figure, an embodiment of this utility model provides a six-sided box inspection device for inspecting labels on the six sides of a box 1. It includes a frame 5, three camera modules mounted on the frame 5, and an adsorption device 4. The adsorption device 4 grips the box 1 to the inspection station and drives the box 1 to rotate. The three camera modules acquire images of the six sides of the box 1 and send them to a host computer. The program in the host computer identifies the labels in the images and checks their compliance, thus ensuring that all six sides of the box 1 can be detected, greatly improving inspection efficiency and accuracy.

[0035] For details, please refer to Figures 2 to 4 Each of the three camera modules mentioned above includes a camera and at least two supplementary lights 34. The first camera module 31 is positioned above the box 1 to capture images of the top surface 11 of the box 1. The second camera module 32 is positioned below the box 1 to capture images of the bottom surface 12 of the box 1. The third camera module 33 is positioned on the side of the box 1 to sequentially capture images of the first side surface 13, the second side surface 14, the third side surface 15, and the fourth side surface 16 of the box 1 during the rotation driven by the adsorption device 4. The host computer communicates with the first camera module 31, the second camera module 32, and the third camera module 33 to facilitate image acquisition.

[0036] Key reference Figure 3 The six-sided box inspection equipment also includes a conveying assembly 2 mounted on the frame 5 for conveying the box 1. Specifically, the conveying assembly 2 includes a first conveying device 21 and a second conveying device 22. The first conveying device 21 transports the box 1 to the inspection station, where the adsorption device 4 picks up the box 1 and moves it to the inspection station for testing. After inspection, the box 1 is transported to the next production process by the second conveying device 22.

[0037] In addition, the first conveying device 21 and the second conveying device 22 are arranged in parallel, and there is a gap 23 between the first conveying device 21 and the second conveying device 22 to avoid the second camera 320 of the second camera module 32.

[0038] In this embodiment, both the first conveying device 21 and the second conveying device 22 are roller conveyor belt mechanisms, which are more suitable for conveying the regularly shaped box 1 in the scenario of this application, and have low maintenance costs. The first conveying device 21, the second conveying device 22 and the second camera module 32 are all mounted on the frame 5, and the second camera module 32 is mounted on a horizontal plane lower than the first conveying device 21 and the second conveying device 22 to avoid affecting the conveying of the box 1.

[0039] In addition, both the first conveying device 21 and the second conveying device 22 are equipped with multiple photoelectric sensors 61 to detect whether there is a box 1 at the corresponding position.

[0040] Optionally, the first conveying device 21 includes a first conveyor belt 210 and a limiting rod 211. The limiting rod 211 is located at the end of the first conveyor belt 210 near the gap 23 and is positioned above the first conveyor belt 210. When the box 1 moves along the first conveyor belt 210, it will eventually come into contact with the limiting rod 211, thus stopping at the inspection station so that the adsorption device 4 can grasp it.

[0041] Further reference Figure 4 and Figure 5 The adsorption device 4 includes a triaxial module 40, a rotating mechanism 41, and an adsorption mechanism 42. The adsorption mechanism 42 can adsorb the top surface 11 of the box 1. The triaxial module 40 is fixed on the frame 5 and positioned above the conveying assembly 2, used to drive the adsorption mechanism 42 to move within the XYZ space. The rotating mechanism 41 is configured to drive the adsorption mechanism 42 to rotate, thereby driving the box 1 adsorbed by the adsorption mechanism 42 to rotate. In this embodiment, the rotating mechanism 41 is a side-axis hollow rotating platform, which reduces the axial installation space; this is existing technology and will not be described in detail here. Furthermore, a second slotted photoelectric sensor 410 is provided on the fixed end 411 of the rotating mechanism 41, and a thin plate is provided on the rotating end 412 of the rotating mechanism 41. The second slotted photoelectric sensor 410 can detect the thin plate to determine whether the box 1 has completed a full rotation, i.e., 360°. This invention, by setting a rotatable adsorption mechanism 42, allows the box 1 to rotate at the detection station. Only one camera module is set on the side of the box 1 to obtain images of the four sides of the box 1, which greatly reduces the production and maintenance costs of the equipment.

[0042] Specifically, refer to Figure 6 and Figure 7 The adsorption mechanism 42 includes a vacuum disk 420 and a plurality of suction cups 421 disposed on the vacuum disk 420. The vacuum disk 420 has an adsorption channel 42a, which is connected to a vacuum generator. The suction cups 421 are connected to the adsorption channel 42a so that suction force can be generated on the suction cups 421. When the adsorption mechanism 42 moves to contact the top surface 11 of the box 1, the suction cups 421 can adhere to the top surface 11 and thus pick up the box 1.

[0043] Optionally, the first camera module 31 is disposed on the side of the vacuum disk 420 away from the suction cup 421. A camera hole 422 is formed on the vacuum disk 420 to avoid obstructing the first camera 310 of the first camera module 31. When the adsorption mechanism 42 moves above the box 1 at the testing station, the first camera module 31 operates first, acquiring an image of the top surface 11. Then, the adsorption mechanism 42 descends and grasps the box 1.

[0044] In addition, the adsorption mechanism 42 also includes a connecting plate 423, a floating rod 424, an elastic element 425, and a fixing block 426. The six-sided detection device for the box also includes a connecting assembly 43 constructed from sheet metal. The connecting assembly 43 is generally L-shaped, and one end is fixed to the output end of the three-axis module 40. The fixed end 411 of the aforementioned rotating mechanism 41 is fixedly connected to the other end of the connecting assembly 43, and the rotating end 412 of the rotating mechanism 41 is fixedly connected to the connecting plate 423. One end of the floating rod 424 is fixedly connected to the vacuum disk 420, and the other end is slidably connected to the connecting plate 423. The fixing block 426 is sleeved and fixed on the floating rod 424, and the elastic element 425 is sleeved on the floating rod 424. One end of the elastic element 425 abuts against the connecting plate 423, and the other end abuts against the fixing block 426. When the adsorption mechanism 42 moves downward and contacts the box 1, the vacuum disk 420 is forced to move upward, causing the floating rod 424 fixed to the vacuum disk 420 to move upward. This further compresses the elastic element 425, achieving a buffering effect and preventing the adsorption mechanism 42 from damaging the box 1. It is worth noting that in this embodiment, the elastic element 425 is preferably a spring.

[0045] Meanwhile, in order to prevent the vacuum disk 420 and suction cup 421 from being damaged by wear, a protective plate 429 supported by sheet metal is also provided on the vacuum disk 420.

[0046] In addition, a first slotted photoelectric sensor 62 is provided on the connecting plate 423, and a detection piece 428 is provided at the corresponding position on the fixing block 426. During the upward movement of the vacuum disk 420, the first slotted photoelectric sensor 62 can detect the detection piece 428, thereby stopping the movement of the triaxial module 40 to avoid damaging the equipment.

[0047] Meanwhile, the adsorption mechanism 42 also includes a limiting bolt 427, which is located on the fixed block 426 near the connecting plate 423. When the vacuum disk 420 moves upward to its limit position, the limiting bolt 427 can abut against the connecting plate 423 to forcibly stop the relative movement between the vacuum disk 420 and the connecting plate 423, thus preventing further damage caused by the failure of the equipment's limiting function in the event of damage to the first slotted photoelectric sensor 62.

[0048] Preferably, the connecting plate 423 is square, and four floating rods 424 are provided, each located at one of the four corners of the connecting plate 423. Two fixing blocks 426 are provided, each located between two floating rods 424, to ensure the stability of the vacuum disk 420 under force.

[0049] Optionally, the six-sided inspection device for the box also includes a two-axis module 330. The two-axis module 330 is mounted on the frame 5, and the third camera module 33 is mounted on the output end of the two-axis module 330. The two-axis module 330 can drive the third camera module 33 to move in the YZ plane, thereby making the device suitable for boxes 1 of various sizes.

[0050] In addition, the first camera module 31, the second camera module 32 and the third camera module 33 mentioned above all include at least two fill lights 34, which are symmetrically arranged on both sides of the lens to ensure the clarity of the photos during shooting.

[0051] The workflow of the six-sided detection device for a topic provided by this utility model is as follows:

[0052] The first conveyor belt 210 first transports the box 1 from the outside to abut against the limit rod 211, and the box 1 stops at the inspection station. Next, the three-axis module 40 drives the adsorption mechanism 42 to move above the box 1. At this time, the first camera module 31 works and captures an image of the top surface 11. Then, the adsorption mechanism 42 descends. When the suction cup 421 on the vacuum disk 420 adsorbs the top surface 11 of the box 1, the three-axis module 40 drives the adsorption mechanism 42 to move and grab the box 1 to the inspection station. At this time, the second camera module 32 is located below the box 1 and captures an image of the bottom surface 12 of the box 1. The third camera module 33 is located on the side of the box 1. At this time, the rotation mechanism 41 drives the adsorption mechanism 42 to rotate, thereby driving the box 1 to rotate. During the rotation of the box 1, the third camera module 33 sequentially captures and acquires images of the first side 13, the second side 14, the third side 15, and the fourth side 16 of the box 1. The host computer judges and identifies whether the label in the image is qualified, thus completing the inspection. Finally, the three-axis module 40 drives the adsorption mechanism 42 to move and places the box 1 on the second conveying device 22, which then transports the tested box 1 outside the equipment.

[0053] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
