Description

Technical Field

[0001] The present invention relates to the technical field of surface defect detection, and in particular to a paper container detection device. Background Art

[0002] Paper container visual inspection devices are mainly used for the inspection of paper cups, paper bowls, paper plates and other edible containers. They collect data to detect defects, stains, shapes, sizes, etc. on the surface of paper containers, and then reject unqualified paper product containers. Usually, the device is installed on the product conveying line.

[0003] In the prior art, conventional visual inspection devices mainly use light sources to illuminate the object to be inspected to achieve the purpose of fill light, which is convenient for camera shooting. However, this type of light source has problems such as uneven light dispersion and high light intensity, which leads to uneven light and dark distribution in the captured pictures, making it inconvenient to detect whether there are defects in the container. The prior art is not convenient for focusing the divergent light and increasing the light source intensity. If the light intensity is simply increased, excessive energy consumption will occur, and the clarity of the shooting will be affected, such as excessive exposure, which affects the accuracy of the detection. Summary of the invention

[0004] Based on this, an object of the present invention is to provide a paper container detection device capable of detecting whether the inner cup body of an outer-wrapped paper cup is evenly coated with glue.

[0005] The present invention provides a paper container detection device, comprising:

[0006] A conveyor belt, a light box, five groups of detection components and a light source component; the light box includes a box body and a light source component located in the box body, the box body is arranged on the conveyor belt, and the box body is provided with a plurality of detection ports and two delivery ports, and the two delivery ports are opened along the transmission path of the conveyor belt; the plurality of detection ports are respectively arranged on the top wall and the side wall of the light box, and four opposite detection ports are opened on the side wall of the light box; each group of the detection components corresponds to one detection port; the light source component is arranged in the light box.

[0007] With such arrangement, after the paper container is accommodated by the light box, it is supplemented with light by cooperating with the light source component, so that the light will not diverge, but will be gathered, thereby improving the light intensity during detection. When the detection component shoots from the detection port, since the number of detection components set is five, the top of the paper container and the four sides are photographed for detection, and the light-gathering function of the light box is used to make the brightness of the photographed photos more uniform, which is more convenient for detection and improves the accuracy of detection.

[0008] In one embodiment, the box body includes: two groups of first side walls and two oppositely arranged second side walls, each of the conveying ports is opened on one of the second side walls, each group of the first side walls is two, the two first side walls of each group are respectively located between the two second side walls, each of the first side walls is provided with a detection port, and the two groups of the first side walls are evenly arranged along the circumference of the box body.

[0009] In one embodiment, there is an angle between the plane where each first side wall is located and the plane where the second side wall is located, and the angle is sixty degrees. In this case, the box body is in a regular hexagonal shape.

[0010] In this way, by setting the box body as a regular hexagon, each group of detection components is at a vertical angle to the first side wall, making shooting more convenient and eliminating the problem of blind spots in shooting. At the same time, there will be no waste of energy costs caused by setting too many detection components.

[0011] In one embodiment, the light source assembly is divided into four groups and respectively arranged on the inner walls of two groups of first side walls. The light source assembly includes: a light source bracket and a light source. The light source bracket is arranged on the inner wall of the box body, and the light source is installed on the light source bracket.

[0012] In this way, by setting the light source into four groups of detection components that match the four side detections, the light intensity is improved, and the sides of the paper container can be fully detected, avoiding the problem of incomplete detection and the problem of uneven brightness of the photos taken.

[0013] In one embodiment, the light source bracket includes: a support plate, two mounting feet and a light source mounting surface; one end of the mounting feet is fixedly mounted on the support plate, and the other end is fixedly connected to the side wall of the first side wall; the light source mounting surface is opened on the support plate; the light source is mounted on the light source mounting surface, the light source is a light strip, and the angle between the light source mounting surface and the first side wall in the vertical direction is forty-five degrees.

[0014] In this arrangement, by fixing a support plate with two mounting feet, the strength of the mechanical structure is made more stable. In addition, the light emitted by the light strip forms an angle of forty-five with the first side wall, so that the light intensity in the light box is better, avoiding the problem of excessive exposure caused by direct exposure to the paper container.

[0015] In one embodiment, the detection component includes: an observation camera and a leg for supporting the observation camera, the observation camera faces the detection port and is arranged perpendicular to the detection port, the leg is fixed on the conveyor belt, the leg is an electric telescope, and the five detection ports are equipped with three electric telescopes responsible for adjusting the height, left and right, and front and back respectively.

[0016] With this arrangement, the observation camera can be adjusted to the best shooting angle by using the electric telescopic device for fine adjustment, thereby improving the detection accuracy. The shooting angle of the observation camera can be adjusted on the three coordinates of X, Y and Z, further improving the detection accuracy.

[0017] Therefore, the present invention has the following advantages compared with the prior art:

[0018] 1. According to the paper container detection device involved in the present invention, after the paper container is contained in the light box, supplementary light is provided with the light source component, so that the light will not be scattered, but the light is gathered, thereby improving the light intensity during detection. When the detection component takes pictures from the detection port, since the number of detection components is five, the top of the paper container and the four sides are photographed for detection. With the light gathering function of the light box, the brightness of the photographed picture is more uniform, which is more convenient for detection and improves the accuracy of detection.

[0019] 2. According to the paper container detection device involved in the present invention, the purpose of multi-faceted detection is achieved by photographing the paper container in five directions. The detection of the four sides of the paper container makes it possible to avoid shooting blind spots on the side of the paper container, thereby improving the detection accuracy. The electric telescopic device is used for fine adjustment to adjust the shooting angle of the observation camera on the three coordinates of X, Y and Z, thereby further improving the detection accuracy.

[0020] 3. According to the paper container detection device involved in the present invention, by utilizing the light emitted by the light strip to form a forty-five angle with the first side wall, the light intensity in the light box is improved, thereby avoiding the problem of excessive exposure caused by direct irradiation of the paper container.

[0035] See also Figure 1 and Figure 2 The embodiment of the present invention provides a paper container detection device, including a conveyor belt 11, a light box 10, five groups of detection components 12 and a light source component 13; the light box 10 includes a box body 101 and a light source component 13 located in the box body 101, the box body 101 is arranged on the conveyor belt 11, and a plurality of detection ports 103 and two conveying ports 104 are arranged on the box body 101, and the two conveying ports 104 are opened along the conveying path of the conveyor belt 11; the plurality of detection ports 103 are respectively arranged on the top wall and the side wall of the light box 10, and four opposite detection ports 103 are opened on the side wall of the light box 10; each group of detection components 12 corresponds to one detection port 103; the light source component 13 is arranged in the light box 10.

[0036] It can be understood that when it is necessary to detect surface defects of paper containers, the paper container moves on the conveyor belt 11, and the light source component 13 in the light box 10 is always on. When the conveyor belt 11 carries the paper container to the shooting point, five groups of detection components 12 begin to shoot the top and sides of the paper container respectively. When the conveyor belt 11 leaves the shooting point with the paper container, it only needs to wait for the next paper container (the paper container will not stop moving during shooting). After the paper container is accommodated by the light box 10, it is supplemented with light by the light source component 13, so that the light will not diverge, and the light is gathered, thereby improving the light intensity during detection. When the detection component 12 shoots from the detection port 103, since the number of detection components 12 is five, the top of the paper container and the four sides are photographed for detection. With the light gathering function of the light box 10, the brightness of the photographed photo is more uniform, which is more convenient for detection and improves the accuracy of detection.

[0037] Combination Figure 3 As shown, the box body 101 includes: two groups of first side walls 1011 and two oppositely arranged second side walls 1012, each conveying port 104 is opened on a second side wall 1012, each group of first side walls 1011 has two, the two first side walls 1011 of each group are respectively located between the two second side walls 1012, each first side wall 1011 is provided with a detection port 103, the two groups of first side walls 1011 are evenly arranged along the circumference of the box body 101, and there is an angle between the plane where each first side wall 1011 is located and the plane where the second side wall 1012 is located, and the angle is sixty degrees. At this time, the shape of the box body 101 is a regular hexagon.

[0038] It can be understood that by setting the box 101 to a regular hexagon, each group of detection components 12 is at a vertical angle to the first side wall 1011, making shooting more convenient and eliminating the problem of blind spots in shooting. At the same time, there will be no waste of energy costs caused by setting too many detection components 12.

[0039] Combination Figure 4 As shown, there are four groups of light source assemblies 13, which are respectively arranged on the inner walls of two groups of first side walls 1011. The light source assemblies 13 include: a light source bracket 131 and a light source 132. The light source bracket 131 is arranged on the inner wall of the box body 101, and the light source 132 is installed on the light source bracket 131.

[0040] It can be understood that by setting the light source 132 to four groups of detection components 12 that match four side detections, the light intensity is improved, and the sides of the paper container can be fully detected, avoiding the problem of incomplete detection and the problem of uneven brightness of the photos taken.

[0041] Combination Figure 3-5As shown, the light source bracket 131 includes: a support plate 100b, two mounting feet 100a and a light source mounting surface 100c; one end of the mounting foot 100a is fixedly mounted on the support plate 100b, and the other end is fixedly connected to the side wall of the first side wall 1011; the light source mounting surface 100c is opened on the support plate 100b; the light source 132 is installed on the light source mounting surface 100c, the light source 132 is a light strip, and the angle range between the light source mounting surface 100c and the first side wall 1011 in the vertical direction is forty-five degrees.

[0042] It can be understood that by fixing a support plate 100b with two mounting feet 100a, the strength of the mechanical structure is made more stable, and the light emitted by the light strip is at a forty-five degree angle to the first side wall 1011, so that the light intensity in the light box 10 is better, avoiding the problem of excessive exposure caused by direct exposure to paper containers.

[0043] Combination Figure 6 As shown, the detection component 12 includes: an observation camera 121 and a leg 122 for supporting the observation camera 121, the observation camera 121 faces the detection port 103 and is arranged vertically with the detection port 103, the leg 122 is fixedly set on the conveyor belt 11, the leg 122 is an electric telescopic device, and the five detection ports 103 are equipped with three electric telescopic devices respectively responsible for adjusting the height, left and right, and front and back.

[0044] It can be understood that when installing, the electric telescope is used to adjust the position of the observation camera 121 on the three coordinate axes of X, Y and Z respectively, so that the shooting angle of the observation camera 121 can be better and the photos taken can be clearer. By using the electric telescope for fine-tuning, the observation camera 121 can adjust the optimal shooting angle, thereby improving the detection accuracy. The shooting angle of the observation camera 121 is adjusted on the three coordinates of X, Y and Z, further improving the detection accuracy.

[0045] The working principle of the paper container detection device is as follows: when it is necessary to detect surface defects of paper containers, the paper container is driven on the conveyor belt 11 and enters from a conveying port 104. The light source assembly 13 in the light box 10 is always on. When the conveyor belt 11 carries the paper container to the shooting point, five groups of observation cameras 121 begin to shoot the top and sides of the paper container respectively. When the conveyor belt 11 carries the paper container away from the shooting point, it is transported away from another conveying port 104 and waits for the next paper container to enter.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
