[0037] The realization of the objectives, functional features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0040] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, can be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprising," "including," indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, or mean any one or any combination thereof. Therefore, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A, B, and C." Exceptions to this definition only occur when combinations of elements, functions, steps, or operations are inherently mutually exclusive in some way. When describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean being directly above another layer or region, or containing other layers or regions between it and another layer or region. Furthermore, if the component is flipped, the layer or region will be located "below" or "under" another layer or region. In embodiments of this application, "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0041] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0042] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0043] In related technologies, finished product inspection in packaging box production lines generally relies on manual inspection. However, manual inspection suffers from problems such as high labor costs, low inspection efficiency, and inconsistent inspection judgment standards.

[0044] In view of the above, and to better understand this application, the detection device of the embodiments of this application will be described in detail below with reference to the accompanying drawings. In the drawings, for ease of drawing, the dimensions in the drawings are not necessarily proportional to the actual dimensions. For clarity of drawing, some structures in the drawings may be hidden or partially shown.

[0045] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the detection device provided in the embodiments of this application; Figure 2 This is a front view of the detection device provided in the embodiments of this application; Figure 3 A schematic diagram of an example steering mechanism is shown.

[0046] like Figures 1 to 3 As shown, this embodiment provides a detection device 10, including a base 100, a transmission line 200, a feeding mechanism 300, a steering mechanism 400, and a detection mechanism 500. The transmission line 200 is mounted on the base 100. The feeding mechanism 300 is mounted on the base 100 and includes a first feeding transfer line 310 and a second feeding transfer line 320, both extending along a first direction (x direction in the figure). The first feeding transfer line 310 and the second feeding transfer line 320 are used to alternately feed packaging boxes 20 to the transmission line 200. The steering mechanism 400 is mounted on the base 100 and includes a first drive module 410 and a first pick-up module 420 connected to the first drive module 410. The first drive module 410 is used to drive the first pick-up module 420 to grip the packaging box 20 and rotate the packaging box 20. The testing mechanism 500 is mounted on the base 100. The testing mechanism 500 includes at least two image acquisition modules 510, all of which face the packaging box 20 on the transmission line 200. The at least two image acquisition modules 510 are located on different sides of the steering mechanism 400 on the transmission line 200.

[0047] Optionally, the first drive module 410 is a combination of a cylinder and a motor. The cylinder part is used to drive the first pickup module 420 to pick up or put down the packaging box 20, and the motor part is used to drive the first pickup module 420 and the packaging box 20 it picks up to rotate together.

[0048] Optionally, the conveyor line 200, the first feeding transfer line 310 and the second feeding transfer line 320 can be at least one of the following forms: chain conveyor line, roller conveyor line, belt conveyor line, suction belt conveyor line, etc., for moving the packaging box 20 on it from one end to the other end.

[0049] Optionally, the packaging box 20 is a rectangular mobile phone packaging box with an opening. The packaging box 20 has an outer long side, an outer short side, an inner long side, an inner short side, an outer surface, edges, and corners. When the packaging box 20 is placed on a horizontal surface with its opening facing upwards, the outer long side refers to the longer exposed side of the packaging box 20 that is parallel to the horizontal plane; the outer short side refers to the shorter exposed side of the packaging box 20 that is parallel to the horizontal plane; the inner long side refers to the longer side of the packaging box 20 that is parallel to the horizontal plane; the inner short side refers to the shorter side of the packaging box 20 that is parallel to the horizontal plane; the edges refer to the sides perpendicular to the horizontal plane; and the corners refer to the angles formed by the intersection of the three planes. The packaging box 20 also contains accessories such as an inner tray and a SIM card ejector tool.

[0050] Optionally, the image acquisition module 510 is a camera, and the detection mechanism 500 also includes a processing module (not shown) electrically connected to the image acquisition module 510. The processing module can be a microprocessor. Images of the packaging box 20 captured by the image acquisition module 510 are transmitted to the processing module. The processing module identifies defect features in the images of the packaging box 20 and determines whether the packaging box 20 captured by the image acquisition module 510 is a good product. Furthermore, the processing module also includes a model training unit, which performs deep learning on the acquired images of the packaging box 20 to obtain a packaging box detection model. The packaging box detection model can continuously correct its defects as the image data captured by the image acquisition module 510 in the detection device 10 accumulates, thereby improving the detection accuracy of the detection device 10.

[0051] It should be noted that the image recognition part of the processing module in this embodiment can adopt any image recognition model in related technologies, and the model training unit in the processing module can also adopt any model training unit in related technologies, as long as the above functions can be achieved. However, the specific image recognition model used, the model training unit, and how image recognition and model training are implemented are not within the scope of protection of this application.

[0052] The detection device 10 provided in this application embodiment, by setting up an image acquisition module 510, captures images of the packaging box 20 and performs automated detection, replacing manual detection, reducing labor costs and improving the detection efficiency of the detection device 10. By setting up a steering mechanism 400 to rotate the packaging box 20, and with two image acquisition modules 510 located on different sides of the steering mechanism 400 on the transmission line 200, the two image acquisition modules 510 can detect the packaging box 20 before and after the steering, reducing the detection blind spot of the packaging box 20 and improving the detection accuracy of the detection device 10. By setting up a first feeding transfer line 310 and a second feeding transfer line 320 that alternately feed the packaging box to the transmission line 200, the transfer efficiency of the packaging box 20 in the detection device 10 is improved, thereby further improving the detection efficiency of the detection device 10.

[0055] Optionally, the third pickup module 340 is a suction cup, and the seventh drive module 330 is a cylinder. The feeding mechanism 300 also includes a first slide rail 350 extending along the second direction (y-direction in the figure), and the seventh drive module 330 is used to drive the third pickup module 340 to slide along the first slide rail 350. The first feeding transfer line 310 and the second feeding transfer line 320 are respectively located on both sides of the transmission line 200 in the second direction y. The third pickup module 340 is located above the transmission line 200, the first feeding transfer line 310, and the second feeding transfer line 320. When the packaging box 20 moves on the first loading transfer line 310 and the second loading transfer line 320, the third picking module 340 picks up the packaging box 20. Then, the seventh drive module 330 drives the third picking module 340 to move along the first slide rail 350 until the packaging box 20 picked up by the third picking module 340 is above the transmission line 200. At this point, the third picking module 340 releases the packaging box 20 onto the transmission line 200 and completes the loading. The first direction x and the second direction y are intersecting. The first direction x can be understood as the front-back direction, and the second direction y can be understood as the left-right direction. Specifically, the first direction x, the second direction y, and the vertical direction intersect in pairs.

[0056] Optionally, two third pickup modules 340 are spaced apart along the second direction y on the first slide rail 350. The two third pickup modules 340 are respectively used to pick up the packaging boxes 20 on the first feeding transfer line 310 and the second feeding transfer line 320. The third pickup module 340 can transfer the packaging boxes 20 to the transmission line 200 at a rate of picking up one packaging box 20 on each of the first feeding transfer line 310 and the second feeding transfer line 320, or it can transfer a set of packaging boxes 20 on the first feeding transfer line 310 first, and then transfer a set of packaging boxes 20 on the second feeding transfer line 320.

[0057] Optionally, the packaging box 20, which is transferred from the feeding mechanism 300 to the transmission line 200, has its opening facing upward and its short side facing the direction of movement of the transmission line 200.

[0058] Please refer to Figure 1 , Figure 2 and Figure 5 , Figure 5 A schematic diagram of the structure of an example first positioning mechanism is shown.

[0059] like Figure 1 , Figure 2 and Figure 5 As shown, in some optional embodiments, the transmission line 200 includes a first transmission line 210 and a second transmission line 220 both extending along a first direction x. The first transmission line 210 and the second transmission line 220 are spaced apart along the first direction x, and the first transmission line 210 is located between the feeding mechanism 300 and the second transmission line 220. The detection device 10 also includes a first positioning mechanism 600 mounted on the base 100. The first positioning mechanism 600 includes a third drive module 601 and a first push block 602 connected to the third drive module 601. The first push block 602 is located above the first transmission line 210, and the third drive module 601 is used to drive the first push block 602 to push the packaging box 20 on the first transmission line 210 to move along a second direction y.

[0060] Optionally, the third drive module 601 is a cylinder, and the two first push blocks 602 are located on both sides of the first transmission line 210 in the second direction y. When the third drive module 601 starts, it drives the two first push blocks 602 to move towards each other along the second direction y and pushes the packaging box 20 to the center line position of the first transmission line 210.

[0061] The detection device 10 provided in this application embodiment uses a first positioning mechanism 600 to position the packaging box 20 transferred from the feeding mechanism 300 to the first transmission line 210, ensuring that each packaging box 20 moves along the same running trajectory on the first transmission line 210, thereby improving the consistency of the shooting angle of each packaging box 20 by the subsequent image acquisition module 510, and further improving the detection accuracy of the detection device 10.

[0062] Please refer to Figure 1 , Figure 2 and Figure 6 , Figure 6 An example is shown. Figure 2 A partial front view of the front section of the detection device in the diagram.

The second image acquisition module 520, the third image acquisition module 530, the fourth image acquisition module 540, the fifth image acquisition module 550, and the sixth image acquisition module 560 all face the first transmission line 210.

[0064] Optionally, the second image acquisition module 520 is used to photograph the edges of the packaging box 20, and the third image acquisition module 530 and the fourth image acquisition module 540 are both used to photograph the accessories inside the packaging box 20, such as ejector pins and inner trays. The second image acquisition module 520, the third image acquisition module 530, and the fourth image acquisition module 540 are all located above the first transmission line 210 and photograph the packaging box 20 on the first transmission line 210 from top to bottom.

[0065] Optionally, the fifth image acquisition module 550 is used to capture the inner long side of the packaging box 20. The fifth image acquisition module 550 is located above the first transmission line 210 and captures the packaging box 20 on the first transmission line 210 from an oblique upward direction and from an oblique downward direction. The sixth image acquisition module 560 is used to capture the outer long side of the packaging box 20. The sixth image acquisition module 560 is located on both sides of the first transmission line 210 in the second direction y and captures the packaging box 20 on the first transmission line 210 from the left and right sides.

[0066] The detection device 10 provided in this application embodiment is configured with a second image acquisition module 520, a third image acquisition module 530, a fourth image acquisition module 540, a fifth image acquisition module 550, and a sixth image acquisition module 560, which are used to identify defects such as protruding edges, dirty accessories, missing accessories, protruding or recessed inner long edges, and protruding or recessed outer long edges of the packaging box 20, respectively, to replace manual inspection, reduce labor costs, and improve the detection efficiency of the detection device.

[0067] Please refer to Figures 1 to 3 , Figure 7 , Figure 7 A schematic diagram of the structure of an example second positioning mechanism is shown.

[0068] like Figures 1 to 3 , Figure 7 As shown, in some optional embodiments, the steering mechanism 400 is located between the first transmission line 210 and the second transmission line 220 in the first direction x. The steering mechanism 400 also includes a second drive module 430 connected to the first pickup module 420. The second drive module 430 is used to drive the first pickup module 420 to transfer the packaging box from the first transmission line 210 to the second transmission line 220.

[0069] Optionally, the steering mechanism 400 further includes a second slide rail 440 extending along a first direction x. The first drive module 410 and the first pickup module 420 are both mounted on the second slide rail 440, which is located above the first transmission line 210 and the second transmission line 220. The second drive module 430 is a cylinder, used to drive the first drive module 410 and the first pickup module 420 to slide along the second slide rail 440, thereby moving the packaging box 20 held by the first pickup module 420 from the first transmission line 210 to the second transmission line 220.

[0070] Optionally, the detection mechanism 500 further includes a first image acquisition module 511, which is located between the first transmission line 210 and the second transmission line 220 in the first direction x, and is located below the steering mechanism 400. The first image acquisition module 511 captures images from bottom to top. When the steering mechanism 400 picks up the packaging box 20 and transfers the packaging box 20 from the first transmission line 210 to the second transmission line 220, the picked-up packaging box 20 passes over the first image acquisition module 511, and the first image acquisition module 511 can capture images of the outer surface of the packaging box 20, especially the lower surface.

[0071] Optionally, when the packaging box 20 is transferred from the first transmission line 210 to the second transmission line 220, the moving direction of the packaging box 20 changes from an opening-up and short-side-to-transmission-line-200 moving direction to an opening-up and long-side-to-transmission-line-200 moving direction.

[0072] Optionally, the detection device 10 further includes a second positioning mechanism 610 mounted on the base 100. The second positioning mechanism 610 includes a fourth drive module 611 and a second push block 612 connected to the fourth drive module 611. The second push block 612 is located above the second transmission line 220. The fourth drive module 611 is used to drive the second push block 612 to move the packaging box 20 on the second transmission line 220 along the second direction y. The fourth drive module 611 is a cylinder. The two second push blocks 612 are respectively located on both sides of the second transmission line 220 in the second direction y. When the fourth drive module 611 is started, it drives the two second push blocks 612 to move towards each other along the second direction y and push the packaging box 20 to the centerline position of the first transmission line 210.

[0073] The detection device 10 provided in this application embodiment, by setting a turning mechanism 400 to change the packaging box 20 from facing forward with its short side forward to facing forward with its long side forward, enables the subsequent image acquisition module 510 to detect different areas of the packaging box 20, reducing the probability of missed detection and increasing the detection range of the detection device 10 for the packaging box 20. By setting a first image acquisition module 511, when the packaging box 20 is clamped and suspended by the turning mechanism 400, the first image acquisition module 511 can take pictures of the packaging box 20 from bottom to top, avoiding the lower surface of the packaging box 20 being missed, further improving the detection range of the detection device 10 for the packaging box 20. By setting a second positioning mechanism 610, the packaging box 20 transferred from the first transmission line 210 to the second transmission line 220 is positioned, ensuring that each packaging box 20 moves along the same running trajectory on the second transmission line 220, thereby improving the consistency of the shooting angle of the subsequent image acquisition module 510 for each packaging box 20, and further improving the detection accuracy of the detection device 10.

[0074] Please refer to Figure 1 , Figure 2 and Figure 8 , Figure 8 An example is shown. Figure 2 A partial front view of the rear section of the detection device.

[0075] like Figure 1 , Figure 2 and Figure 8 As shown, in some optional embodiments, the image acquisition module 510 further includes a seventh image acquisition module 570, an eighth image acquisition module 580 and a ninth image acquisition module 590 arranged sequentially along the first direction x, with the seventh image acquisition module 570, the eighth image acquisition module 580 and the ninth image acquisition module 590 all facing the second transmission line 220.

[0076] Optionally, the seventh image acquisition module 570 is used to capture the corners of the packaging box 20, and the eighth and ninth image acquisition modules 580 are used to capture the outer and inner short sides of the packaging box 20, respectively. The seventh and eighth image acquisition modules 570 are located above the second transmission line 220. The seventh image acquisition module 570 captures the packaging box 20 on the second transmission line 220 from top to bottom, while the eighth image acquisition module 580 is located on both sides of the second transmission line 220 in the second direction y and captures the packaging box 20 from the left and right sides. The ninth image acquisition module 590 captures the packaging box 20 on the second transmission line 220 from an angled upward to an angled downward.

[0077] The detection device 10 provided in this application embodiment is configured with a seventh image acquisition module 570, an eighth image acquisition module 580 and a ninth image acquisition module 590, which are used to identify defects such as protruding corners, protruding or recessed inner short sides, and protruding or recessed outer short sides of the packaging box 20, respectively, to replace manual inspection, reduce labor costs and improve the detection efficiency of the detection device.

[0078] Please refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 , Figure 9 A schematic diagram of an example rejection mechanism is shown.

[0079] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, in some optional embodiments, the detection device 10 further includes a defective product transmission line 700 and a rejection mechanism 710 both mounted on the base 100. The defective product transmission line 700 is connected to the second transmission line 220, and the extension direction of the defective product transmission line 700 intersects with the extension direction of the second transmission line 220. The rejection mechanism 710 includes a fifth drive module 711 and a third push block 712 connected to the fifth drive module 711. The third push block 712 is located above the second transmission line 220. The fifth drive module 711 is used to drive the third push block 712 to push the packaging box 20 on the second transmission line 220 to move along the second direction y until the packaging box 20 moves onto the defective product transmission line 700.

[0080] Optionally, all image acquisition modules 510 are located on the side of the rejection mechanism 710 facing the feeding mechanism 300 in the first direction x, and the rejection mechanism 710 is electrically connected to the processing module. When any image acquisition module 510 detects a defect in the packaging box 20, the processing module transmits a signal to the rejection mechanism 710, and the rejection mechanism 710 moves the packaging box 20 from the second transmission line 220 to the defective product transmission line 700.

[0081] Optionally, the defective transmission line 700 can be extended along a curve.

[0082] The detection device 10 provided in this application embodiment, by setting up a defective product transmission line 700 and a rejection mechanism 710, transfers defective packaging boxes 20 from the second transmission line 220 to the defective product transmission line 700, thereby realizing the function of separating qualified packaging boxes 20 from defective packaging boxes 20.

[0083] Please refer to Figure 1 , Figure 2 , Figure 8 and Figure 10 , Figure 10 A schematic diagram of an example flipping mechanism is shown.

[0084] like Figure 1 , Figure 2 , Figure 8 and Figure 10 The transmission line 200 further includes a third transmission line 230 extending along a first direction x. The third transmission line 230 and the second transmission line 220 are spaced apart along the first direction x, with the second transmission line 220 located between the first transmission line 210 and the third transmission line 230. The detection device 10 also includes a flipping mechanism 800 mounted on the base 100. The flipping mechanism 800 includes a sixth drive module 810 and a second pickup module 820 connected to the sixth drive module 810. The sixth drive module 810 is used to drive the second pickup module 820 to grip the packaging box 20 and flip the packaging box 20, transferring it from the second transmission line 220 to the third transmission line 230.

[0085] Optionally, the second pickup module 820 includes at least one circular chuck 821, the axis of which is perpendicular to both the vertical direction and the first direction x. The circular chuck 821 has at least one slot 822 for receiving the packaging box 20. When the packaging box 20 on the second transmission line 220 is at least partially received in the slot 822, the sixth drive module 810 drives the circular chuck 821 to rotate along its axis and flip the packaging box 20, transferring it from the second transmission line 220 to the third transmission line 230.

[0086] Optionally, the second pickup module 820 includes two circular chucks 821 spaced apart along their axes. When the packaging box 20 on the second transmission line 220 is transferred to the second pickup module 820, the two sides of the packaging box 20 are respectively accommodated in the slots 822 of the two circular chucks 821.

[0087] Optionally, the sixth drive module 810 is a motor, which drives the circular chuck 821 to rotate along its axial direction.

[0088] The detection device 10 provided in this application embodiment, by setting a sixth driving module 810 and a second picking module 820, the circular chuck 821 in the second picking module 820 can rotate together with the packaging box 20 that is engaged by the card slot 822 when rotating, so as to transfer the packaging box 20 from the second transmission line 220 to the third transmission line 230, and flip the packaging box 20 so that the opening faces down, which is convenient for subsequent stacking of the packaging box 20.
