[0047] As introduced in the background, in the packaging industry, it involves using paper boxes to package products, and glue is required to bond the paper boxes during the production process of the paper boxes. In order to ensure the reliability of the paper boxes, generally, manual force is applied to the paper boxes to judge whether the bonded parts of the paper boxes are firm. Since during the manual detection process, on the one hand, the manual efficiency is relatively low; on the other hand, it is relatively difficult for manual operation to control the force applied to the paper boxes, so the detection results of the paper boxes are not ideal.

[0048] In order to better solve this problem, researchers proposed a paper box detection device, intending to improve the accuracy of detecting the bonded parts of the paper boxes through this paper box detection device, and at the same time, it can also improve the efficiency of the paper boxes.

[0049] It should be noted that the paper box 600 includes opposite first paper surface 610 and second paper surface 620, and the first paper surface 610 and the second paper surface 620 are bonded by glue. When a force is applied to the first paper surface 610 and the second paper surface 620, if the bonding part of the paper box 600 meets the requirements, the first paper surface 610 and the second paper surface 620 of the paper box 600 will partially separate at the bonding part; if the bonding part of the paper box 600 does not meet the requirements, the first paper surface 610 and the second paper surface 620 of the paper box 600 will completely separate at the bonding part.

[0050] Referring to Figure 1 as shown, Figure 1 is a module schematic diagram of the paper box detection device shown in an embodiment of the present application, Figure 2 and Figure 1 is a module schematic diagram of another state of the paper box detection device in Figure 1 . The paper box detection device includes: a first driving mechanism 100, a second driving mechanism 200, a light source module 300, and an image recognition module 400. Among them, the first driving mechanism 100 and the second driving mechanism 200 can be used to apply a force to the first paper surface 610 and the second paper surface 620 of the paper box 600 and separate the first paper surface 610 and the second paper surface 620. The moving direction of the paper box driven by the first driving mechanism 100 can refer to Figure 1 the direction pointed by the arrow a in

[0051] , and the moving direction of the paper box driven by the second driving mechanism 200 can refer to

[0052] the direction pointed by the arrow b in Figure 1 . During this process, it can be understood as simulating the artificial separation of the bonding part of the paper box 600. The light source module 300 can converge light to the bonding part of the paper box 600, and the image recognition module 400 can obtain the state of the separation area of the bonding part of the paper box 600 and obtain the brightness information of the separation area of the bonding part of the paper box 600 under the illumination of the light source module 300, so as to judge whether the bonding part of the paper box 600 meets the requirements.

[0051] In this embodiment, by controlling the forces applied by the first driving mechanism 100 and the second driving mechanism 200 to the first paper surface 610 and the second paper surface 620, the forces applied to the paper box 600 are more stable than those of manual operation. For example, when the first driving mechanism 100 acts on the first paper surface 610 and the second driving mechanism 200 acts on the second paper surface 620, at this time, the stroke of the first driving mechanism 100 driving the first paper surface 610 to move or the stroke of the second driving mechanism 200 acting on the second paper surface 620 to move can be controlled, so as to be able to adjust the force applied to the paper box 600. In addition, the first driving mechanism 100 and the second driving mechanism 200 can continuously detect during the process of detecting the paper box 600, so the efficiency is higher than that of manual operation.

[0052] Specifically, the first driving mechanism 100 and the second driving mechanism 200 are used to separate the first paper surface 610 and the second paper surface 620 that are opposite to the bonding part of the paper box 600; the light source module 300 converges the light source at the bonding part of the paper box 600; the image recognition module 400 is controlled to obtain the brightness information of the first paper surface 610 and the second paper surface 620 in the separation area of the bonding part of the paper box 600 and determine whether the bonding part of the paper box 600 meets the requirements.

[0053] It should be noted that the first driving mechanism 100 and the second driving mechanism 200 may both include vacuum suckers, and the first paper surface 610 and the second paper surface 620 are separated by driving the vacuum suckers to move in opposite directions; or the first driving mechanism 100 can fix the first paper surface 610, and the second driving mechanism 200 drives the second paper surface 620 to move through the vacuum sucker. The light source module 300 may include multiple groups of strip lights, and the converging direction of the light source can be realized by changing the angle of the lamp. Of course, the way of converging the light source by the light source module 300 is not limited to this. The image recognition module 400 may include a camera and a control module. The camera can be used to take pictures, and the control module can process the taken pictures. Multiple picture processing programs are preset in the control module.

[0054] In this embodiment, when it is necessary to detect the paper box 600, the first driving mechanism 100 and the second driving mechanism 200 apply force to the bonding part of the paper box 600 and partially separate the first paper surface 610 and the second paper surface 620 at the bonding part of the paper box 600; then the light source module 300 converges the light source at the bonding part of the paper box 600, and the image recognition module 400 can determine whether the bonding part of the paper box 600 meets the requirements by recognizing the brightness information of the first paper surface 610 and the second paper surface 620 at the bonding part.

[0055] It should be noted that when the first paper surface 610 and the second paper surface 620 of the paper box 600 meet the requirements at the bonding part, when the first driving mechanism 100 and the second driving mechanism 200 separate the bonding part of the first paper surface 610 and the second paper surface 620, at this time, the first paper surface 610 and the second paper surface 620 will not be completely separated at the bonding part. When the converging light source of the light source module 300 reaches the separated bonding part, a relatively bright light spot or bright area will be formed at the edge of the bonding part. For example, when the light source module 300 converges the light source to the bonding part, a first light spot can be formed at the edge of the first paper surface 610, and at the same time, a second light spot can be formed at the edge of the second paper surface 620. The image recognition module 400 can determine whether the bonding part of the paper box 600 meets the requirements by obtaining the distance between the first light spot and the second light spot. The viewing angle range of the image recognition module 400 can refer to Figure 2the angle α standard in; alternatively, the image recognition module 400 can calculate the bright area in the separation area of the glued part of the paper box 600, and judge whether the glued part of the paper box 600 meets the requirements by calculating the bright area.

[0056] When the first paper surface 610 and the second paper surface 620 do not meet the requirements at the glued part, when the first driving mechanism 100 and the second driving mechanism 200 separate the glued part of the first paper surface 610 and the second paper surface 620, at this time the first paper surface 610 and the second paper surface 620 are completely separated. When the converging light source of the light source module 300 converges to the separated glued part, since the first paper surface 610 and the second paper surface 620 are in a separated state at the glued part, no light spot can be formed at the edge of the glued part of the paper surface or the brightness of the glued part is relatively dim, and the image recognition module 400 can judge that the current paper box 600 does not meet the requirements.

[0057] In this application, when separating the glued part of the paper box 600 through the first driving mechanism 100 and the second driving mechanism 200, the acting forces applied by the first driving mechanism 100 and the second driving mechanism 200 to the paper box 600 can be controlled, and at the same time, combined with the image recognition module 400, the accuracy of detecting the glued part of the paper box 600 can be improved; in addition, applying forces to the paper box 600 through the first driving mechanism 100 and the second driving mechanism 200 can work continuously compared with manual work, so the efficiency is also higher.

[0058] The researchers combined with the conveying situation of a paper box 600. The paper box 600 may be conveyed at the work station. In this case, only one of the first driving mechanism 100 or the second driving mechanism 200 needs to fix the paper box 600 to the work station, and the other applies an acting force to the paper box 600, then the glued part of the paper box 600 can be separated.

[0059] Specifically, in an embodiment, refer to Figure 1 and Figure 2 As shown, the first driving mechanism 100 includes a first telescopic end 110 that can reciprocate, wherein the first telescopic end 110 of the first driving mechanism 100 is used to press the first paper surface 610 at the work station. The second driving mechanism 200 includes a second telescopic end 210 that can reciprocate, wherein an adsorption end 220 is arranged on the second telescopic end 210, and the adsorption end 220 of the second driving mechanism 200 is used to adsorb the second paper surface 620.

[0060] In this embodiment, when the paper box 600 moves to the preset working station, the first driving mechanism 100 can press the first paper surface 610 against the working station through the telescopic movement of the first telescopic end 110. It can be understood that the paper box 600 is in a fixed state. Then, the second driving mechanism 200 can drive the adsorption end 220 to move through the second telescopic end 210. The adsorption end 220 can adsorb the second paper surface 620 and drive the second paper surface 620 to move in a direction away from the first paper surface 610. At this time, the first paper surface 610 and the second paper surface 620 can be partially separated at the bonding place.

[0061] It should be noted that the first driving mechanism 100 can include a cylinder, and the piston rod of the cylinder can be the first telescopic end 110; the second driving mechanism 200 can include a cylinder, and the piston rod of the cylinder can be the second telescopic end 210. The adsorption end 220 in the second driving mechanism 200 can be a vacuum suction cup 221, and the second paper surface 620 of the paper box 600 can be picked up through the vacuum suction cup 221. The advantage of using the vacuum suction cup 221 is that the vacuum suction cup 221 causes less damage to the surface of the paper box 600 when adsorbing the paper box 600.

[0062] Considering that the stroke of the first telescopic end 110 of the first driving mechanism 100 and the second telescopic end 210 of the second mechanism are limited, in order to better solve this problem. The researchers thought of setting an abutting portion 120 on the first telescopic end 110 to extend the movable stroke of the first driving mechanism 100. At the same time, the second driving mechanism 200 is arranged on the first telescopic end 110, so that the moving distance of the second driving mechanism 200 can also be enlarged.

[0063] Specifically, in one embodiment, refer to Figure 1 and Figure 3 As shown, the paper box detection device further includes a connection component 500. The first driving mechanism 100 further includes an abutting portion 120. The connection component 500 is arranged on the first telescopic end 110. One end of the abutting portion 120 is arranged on the connection component 500, and the second driving mechanism 200 is fixed on the connection component 500.

[0064] In this embodiment, when the first driving mechanism 100 starts to work, the first telescopic end 110 of the first driving mechanism 100 drives the abutting portion 120 to move through the connection component 500, and presses the first paper surface 610 of the paper box 600 through the abutting portion 120; at the same time, the first telescopic end 110 can also drive the second driving mechanism 200 to move through the connection component 500, thereby also enlarging the moving stroke of the second driving mechanism 200 and making the second driving mechanism 200 closer to the surface of the paper box 600.

[0065] Further, in one embodiment, refer to Figure 3As shown, the connecting component 500 includes a first connecting plate 510 and a second connecting plate 520 that are intersectingly connected. The first connecting plate 510 is disposed at the first telescopic end 110 of the first driving mechanism 100, the abutting portion 120 of the first driving mechanism 100 is provided on the first connecting plate 510, the second connecting plate 520 protrudes from the first driving mechanism 100, and the second driving mechanism 200 is disposed on the second connecting plate 520.

[0066] In this embodiment, the abutting portion 120 in the first driving mechanism 100 is connected by the first connecting plate 510 in the connecting component 500, and the second driving mechanism 200 is connected by the second connecting plate 520 that protrudes from the first driving mechanism 100. In this way, the abutting portion 120 in the first driving mechanism 100 and the adsorption end 220 of the second driving mechanism 200 can be separated by a certain distance to prevent interference between the two during movement.

[0067] In one embodiment, refer to Figure 3 As shown, the abutting portion 120 includes a connecting rod 121 and a fixing plate 122. One end of the connecting rod 121 is disposed on the connecting component 500, the other end of the connecting rod 121 is provided with the fixing plate 122, and the light source module 300 is disposed on the fixing plate 122 and is used to press against the first paper surface 610. In this embodiment, the movement of the first telescopic end 110 of the first driving mechanism 100 can drive the connecting rod 121 and the fixing plate 122 to move. When the external fusion design of the light source module 300 is on the fixing plate 122, on the one hand, the outside of the light source module 300 can press against the paper box 600 to achieve the effect of fixing the paper box 600; on the other hand, the light source module 300 can approach the paper box 600. Therefore, the converging light source of the light source module 300 can better enter the bonding part of the paper box 600.

[0068] Since the sizes of the products are different, the sizes of the packaging boxes for the products are also different. In order for the adsorption end 220 of the second driving mechanism 200 to have a greater adsorption force to better separate the bonding part of the paper box 600, a plurality of vacuum suction cups 221 can be provided on the adsorption end 220.

[0069] When a plurality of vacuum suction cups 221 are provided on the adsorption end 220, in order to make the acting forces exerted by the plurality of vacuum suction cups 221 on the paper box 600 more uniform, it is necessary to adaptively adjust the positions of the plurality of vacuum suction cups 221. Specifically, in one embodiment, refer to Figure 3 As shown, the second driving mechanism 200 further includes an adjusting plate 230 and a plurality of mounting seats 240 that can move relative to the adjusting plate 230. Each vacuum suction cup 221 is correspondingly disposed on the mounting seat 240.

[0070] In this embodiment, when it is necessary to adjust the position of the vacuum suction cup 221, the mounting seat 240 can be moved relative to the adjusting plate 230 at this time. When the position of the mounting seat 240 changes, the position of the vacuum suction cup 221 provided on the mounting seat 240 can also change. It should be noted that the number of the mounting seats 240 should be the same as the number of the vacuum suction cups 221.

[0071] Further, in one embodiment, refer to Figure 3 As shown, the adjusting plate 230 is provided with an adjusting groove 231, one end of the mounting seat 240 is arranged in the adjusting groove 231 and can move relative to the adjusting groove 231. The second driving mechanism 200 further includes a fastening member 250, and the fastening member 250 fixes the mounting seat 240 in the adjusting groove 231.

[0072] In this embodiment, when it is necessary to adjust the positions of multiple vacuum suction cups 221, the multiple mounting seats 240 can be respectively slid relative to the adjusting grooves 231 of the adjusting plate 230 at this time. When the positions of the mounting seats 240 are determined, the mounting grooves can be fixed in the adjusting grooves 231 through the fastening members 250 at this time. The fastening member 250 can be a nut. For example, a threaded section can be arranged at one end of the mounting seat 240 in the adjusting groove 231, and when the nut is tightly connected to the threaded section, the threaded section can be fixed in the adjusting groove 231.

[0073] The present application also proposes a detection method for the above-mentioned carton detection device. The flowchart of the detection method can be referred to Figure 4 As shown. The detection method includes the steps:

[0074] S110: Separate the first paper surface 610 and the second paper surface 620 opposite to the bonding place of the carton 600 through the first driving mechanism 100 and the second driving mechanism 200;

[0075] S120: Converge the light source at the bonding place of the carton 600 through the light source module 300;

[0076] S130: Obtain the first light spot and the second light spot generated by the light source module 300 at the bonding place of the carton 600 through the image recognition module 400, and calculate the distance between the first light spot and the second light spot through the image recognition module 400 and compare it with a preset threshold range;

[0077] S140: When the distance between the first light spot and the second light spot is within the preset threshold range, the carton 600 meets the requirements.

[0078] In this embodiment, the light source converged by the light source module 300 is incident on the bonding portion of the paper box 600. If the bonding portion of the paper box 600 meets the requirements, that is, after the light source enters the bonding portion, it will be reflected on the paper surface of the bonding portion, and relatively bright first and second light spots will exist at the edges of the bonding portion of the paper box 600. For example, a first light spot can be formed at the edge of the first paper surface 610, and a second light spot can be formed at the edge of the second paper surface 620. The image recognition module 400 can determine whether the paper box 600 is bonded and whether the bonding meets the requirements by recognizing the distance between the first and second light spots.

[0079] In another embodiment, when the image recognition module 400 may not recognize the first and / or second light spots at the bonding portion of the paper box 600, the brightness area of the bonding portion can be calculated at this time to determine whether the bonding portion meets the requirements. The flowchart of the detection method can be referred to Figure 5 as shown. The detection method further includes the steps:

[0080] S150: When the image recognition module 400 does not recognize the first and / or second light spots, calculate the area of the brightness region at the bonding portion of the paper box 600 through the image recognition module 400, and compare it with the set area threshold range;

[0081] S160: When the area calculated by the image recognition module 400 is within the set area threshold range, the paper box 600 meets the requirements.

[0082] In this embodiment, calculating the brightness area of the bonding portion through the image recognition module 400 and comparing it with the set threshold can also determine whether the current paper box 600 meets the requirements.

[0083] It should be noted that when the bonding portion of the paper box 600 is not bonded, no light spots, such as the first or second light spot, will be generated when the light source module 300 irradiates the bonding portion. The light source generated by the light source module 300 directly passes through the separation area of the bonding portion of the paper box 600. At this time, the separation area of the bonding portion of the paper box 600 is relatively dark and cannot be calculated by calculating the distance between the first and second light spots; in addition, since the separation area of the bonding portion of the paper box 600 is dark, it does not meet the requirements when calculating the brightness area here.

[0084] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0085] The above embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several variations and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
