Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment manufacturing, and in particular to a packaging box appearance testing equipment which is beneficial to defective product sorting operations. Background Art

[0002] Packaging box inspection is a simple and single task, but it is tedious because of the huge number of products. The packaging boxes need to be inspected, and the packaging boxes are now colored and even have stickers with product specifications, production and origin. It is required to conduct detailed inspections on multiple sides of the packaging box to ensure product quality. If there are defects on the surface of the box, it will inevitably cause great trouble to the subsequent product launch.

[0003] Usually, the packaging box is inspected manually, that is, the quality inspection worker inspects each side of the product coming down the assembly line, checks whether the appearance of the color box is damaged, whether the labels and stickers on the color box are printed correctly, and whether there are anti-tampering labels, so as to find and select defective products from a large number of finished products. However, the workers who work in this way are very likely to get tired and miss inspections when facing a large number of products, so that they cannot meet the higher product quality requirements. Recently, some automatic packaging box appearance inspection equipment has appeared on the market, which is equipped with a machine, a conveyor belt, a camera unit, a control unit and a sorting manipulator. In the process of the conveyor belt carrying the packaging box to be inspected, the camera unit takes images of each side of each packaging box in real time, and feeds them back to the control unit in real time. After image processing and analysis, it is determined whether the appearance of the packaging box meets the quality inspection standards; if it meets the standards, it will continue to flow along the conveyor belt until it reaches the finished product box; if it does not meet the standards, the control unit sends an action signal to the sorting manipulator, and the sorting manipulator immediately takes action to remove the defective packaging box from the conveyor line. In actual operation, the sorting robot has a good use effect, high sorting accuracy and efficiency. However, the purchase cost of the sorting robot is high, and it needs to be equipped with highly professional programmers. Moreover, the use and maintenance cost of the sorting robot is high. In addition, what is more troublesome is that when the model of the packaging box to be tested changes, the program used to control the sorting robot must also be adjusted accordingly, which is very inconvenient. Therefore, it is urgent for technicians to solve the above problems. Summary of the invention

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience in this industry, which ultimately led to the emergence of a packaging box appearance inspection device that is conducive to defective product sorting operations.

[0005] In order to solve the above technical problems, the present invention relates to a packaging box appearance inspection device that is conducive to defective product sorting operations, including a machine, a conveying part and a camera part. The machine includes a machine base and a protective cabin. The protective cabin can be detachably buckled on the machine base to form a detection chamber together. The conveying part is used to carry the packaging box to be inspected and cross the detection chamber from left to right. The camera part includes a high-speed CCD camera and a high-speed CCD camera bracket. The high-speed CCD camera bracket is used to install the high-speed CCD camera, and it is supported by the machine. The number of high-speed CCD cameras is set to be multiple, evenly distributed on the periphery of the conveying part, so as to be used to capture images of each side of the packaging box to be inspected in real time. The conveying part includes a first belt conveying part and a second belt conveying part. The first belt conveying part and the second belt conveying part are both supported by the machine base, operate independently of each other, and are arranged side by side along the front and back direction. The packaging box appearance inspection device that is conducive to defective product sorting operations also includes a wind-powered defective product sorting part. The wind-powered defective product sorting section is built into the detection chamber, and includes a mounting base, a blow box, a pressure air output section, a front discharge box, and a rear discharge box. The mounting base is fixed to the neutral position of the first belt conveyor section and the second belt conveyor section. The pressure air output section can be detachably fixed to the machine base, and is arranged directly below the conveying section, which continuously provides air with a set wind pressure to the blow box. The blow box can be detachably fixed to the mounting base, and its front air outlet and rear air outlet correspond to the first belt conveyor section and the second belt conveyor section, respectively. The front discharge box and the rear discharge box can be detachably fixed to the machine base, and correspond to the front and rear air outlets of the blow box, respectively.

[0006] As a further improvement of the technical solution of the present invention, the blow box includes a box body, a front sealing plate and a rear sealing plate. The box body is a sheet metal bending part, and is connected in sequence by a left connecting section, a main section and a right connecting section. The left connecting section and the right connecting section are both detachably connected to the mounting base plate by means of a screw assembly. The front sealing plate and the rear sealing plate are respectively welded and fixed to the front and rear ends of the main section. The front air outlet and the rear air outlet are respectively opened on the front sealing plate and the rear sealing plate.

[0007] As a further improvement of the technical solution of the present invention, the front discharge box is preferably a sheet metal bending part, and it includes a front discharge box body, a front bottom connection part and a front side connection part. The front bottom connection part is detachably connected to the machine base by means of a screw assembly, and includes a first front bottom connection part formed by the left side wall of the front discharge box body continuing to extend downward and folding outward 90°, and a second front bottom connection part formed by the right side wall of the front discharge box body continuing to extend downward and folding outward 90°. The front side connection part is also detachably connected to the front side wall of the protective cabin by means of a screw assembly, and it is formed by the front side wall of the front discharge box body continuing to extend forward and folding outward 90°.

[0008] As a further improvement of the technical solution of the present invention, the front material discharging box also includes a first front material baffle plate and a second front material baffle plate. The first front material baffle plate is formed by continuing to extend backward from the left side wall of the front material discharging box body and folding outward at a set angle. The second front material baffle plate is formed by continuing to extend backward from the right side wall of the front material discharging box body and folding outward at a set angle.

[0009] Analogous to the above-mentioned front discharge box, it is preferably a sheet metal bending part, and it includes a rear discharge box body, a rear bottom surface connection part and a rear side surface connection part. The rear bottom surface connection part is detachably connected to the machine base by means of a screw assembly, and includes a first rear bottom surface connection part formed by the left side wall of the rear discharge box body continuing to extend downward and folding outward 90°, and a second rear bottom surface connection part formed by the right side wall of the rear discharge box body continuing to extend downward and folding outward 90°. The rear side surface connection part is also detachably connected to the rear side wall of the protective cabin by means of a screw assembly, and it is formed by the rear side wall of the rear discharge box body continuing to extend forward and folding outward 90°.

[0010] As a further improvement of the technical solution of the present invention, the rear material discharging box further includes a first rear material baffle plate and a second rear material baffle plate. The first rear material baffle plate is formed by continuing to extend backward from the left side wall of the rear material discharging box body and folding outward at a set angle. The second rear material baffle plate is formed by continuing to extend backward from the right side wall of the rear material discharging box body and folding outward at a set angle.

[0011] Compared with the traditional design structure of the packaging box appearance inspection equipment that is conducive to the defective product sorting operation, in the technical scheme disclosed in the present invention, it uses the pressurized gas provided by the pressure air output part to realize the removal of defective products from the packaging box, which is convenient and fast, and the implementation cost and the use and maintenance cost are low; in addition, under the premise of satisfying the good sorting function, the design structure of the packaging box appearance inspection equipment is optimized as much as possible, and by setting up a set of pressure air output parts, the defective product sorting operations on the first belt conveyor part and the second belt conveyor part can be taken into account at the same time, thereby making the miniaturization design goal of the packaging box appearance inspection equipment possible.

DETAILED DESCRIPTION

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 The three-dimensional schematic diagram of the packaging box appearance inspection device that is conducive to the defective product sorting operation in the present invention is shown. It can be seen that it is mainly composed of a machine 1, a conveying part 2, a camera part 3, and a wind-powered defective product sorting part 4. Among them, the machine 1 includes a base 11 and a protective cabin 12. The protective cabin 12 is a sheet metal part, which is detachably buckled on the base 11 with the help of screws to form a detection cavity 13 together. The conveying part 2 is used to carry the packaging box to be inspected and cross the above-mentioned detection cavity 13 from left to right. The camera part 3 includes a high-speed CCD camera and a high-speed CCD camera bracket. The high-speed CCD camera bracket is used to install the high-speed CCD camera, and it is supported by the machine 1. The number of high-speed CCD cameras is set to be multiple, evenly distributed on the periphery of the conveying part 2, so as to be used to capture images of each side of the packaging box to be inspected in real time. The conveying part 2 includes a first belt conveyor part 21 and a second belt conveyor part 22. The first belt conveyor 21 and the second belt conveyor 22 are both supported by the base 11, operate independently of each other, and are arranged side by side along the front-to-back direction. The wind defective product sorting unit 4 is built into the detection chamber 13, and its front and rear air outlets correspond to the first belt conveyor 21 and the second belt conveyor 22 respectively. During the actual operation of the packaging box appearance inspection equipment, the wind defective product sorting unit 4 uses pressurized gas to remove defective packaging boxes, which is convenient and fast, and the implementation cost and use and maintenance cost are low.

[0024] As a further refinement of the structure of the packaging box appearance inspection equipment that facilitates the defective product sorting operation, the wind defective product sorting section 4 includes a mounting base 41, a blow box 42, a pressure wind output section 43, a front discharge box 44, and a rear discharge box 45. The mounting base 41 is fixed to the neutral position of the first belt conveyor 21 and the second belt conveyor 22. The blow box 42 is detachably fixed to the mounting base 41, and its front air outlet and rear air outlet correspond to the first belt conveyor 21 and the second belt conveyor 22 respectively. The pressure wind output section 43 is detachably fixed to the base 11, and is arranged directly below the first belt conveyor 21 and the second belt conveyor 22 to continuously provide pressure wind for the blow box 42. The pressure wind output section 43 includes a first pressure air duct and a second pressure air duct that correspond to the front air outlet and the rear air outlet of the blow box 42, respectively, to continuously provide air with a set wind pressure to the front air outlet and the rear air outlet at the same time. The front discharge box 44 and the rear discharge box 45 are both detachably fixed to the base 11, and are respectively arranged on the outside of the first belt conveyor 21 and the second belt conveyor 22, and correspond to the front and rear air outlets of the blowing box 42 respectively (such as Figure 2 , 3 , 4). When defective products are transported to the position to be sorted, the pressure air output unit 43 is activated, and the defective products on the first belt conveyor 21 or the second belt conveyor 22 are blown away through the front air outlet or the rear air outlet. The front air outlet and the rear air outlet on the blowing box 42 can output pressure gas separately or simultaneously, which is determined by whether the corresponding package box after inspection is a defective product.

[0025] In addition, it is necessary to explain that, under the premise of satisfying the good sorting function, the design structure of the packaging box appearance inspection equipment is optimized as much as possible. By setting a set of pressure air output parts 43, the defective product sorting operation on the first belt conveyor part 21 and the second belt conveyor part 22 can be taken into account at the same time (such as Figure 2 ), thus making the miniaturization design goal of packaging box appearance inspection equipment possible.

[0026] In order to reduce the difficulty of manufacturing, reduce the manufacturing cost and its own weight, as a further optimization of the structure of the above-mentioned packaging box appearance inspection equipment that is conducive to the defective product sorting operation, the blowing box 42 is preferably welded by several parts such as the box body 421, the front sealing plate 422 and the rear sealing plate 423. The box body 421 is a sheet metal bending part. Along the direction from left to right, the box body 421 is connected in sequence by the left connecting section 4211, the main body section 4212 and the right connecting section 4213. The left connecting section 4211 and the right connecting section 4213 are both detachably connected to the mounting base plate 41 by means of a screw assembly. The front sealing plate 422 and the rear sealing plate 423 are respectively welded and fixed to the front and rear ends of the main body section 4212. The front air outlet and the rear air outlet are respectively opened on the front sealing plate 422 and the rear sealing plate 423 (such as Figure 5 , 6 ).

[0027] As a further refinement of the structure of the above-mentioned front discharge box 44, it is a sheet metal bending part, and it is mainly composed of several parts such as a front discharge box body part 441, a front bottom surface connecting part 442 and a front side surface connecting part 443. The front bottom surface connecting part 442 is detachably connected to the machine base 11 by means of a screw assembly, and includes a first front bottom surface connecting part 4421 formed by the left side wall of the front discharge box body part 441 continuing to extend downward and folding outward 90°, and a second front bottom surface connecting part 4422 formed by the right side wall of the front discharge box body part 441 continuing to extend downward and folding outward 90°. The front side surface connecting part 443 is also detachably connected to the front side wall of the protective cabin 12 by means of a screw assembly, and it is formed by the front side wall of the front discharge box body part 441 continuing to extend forward and folding outward 90° (such as Figure 7 As shown in ). In this way, the weight and manufacturing difficulty of the front discharge box 44 are effectively reduced, and it is convenient to perform a replacement operation later.

[0028] In order to increase the effective inlet width of the front discharge box 44 as much as possible and reduce the difficulty of feeding defective products, its appearance is preferably "trumpet-shaped", that is, a first front baffle plate 444 and a second front baffle plate 445 are added to its rear side wall. The first front baffle plate 444 is formed by continuing to extend backward from the left side wall of the front discharge box body 441 and folding outward at a set angle. The second front baffle plate 445 is formed by continuing to extend backward from the right side wall of the front discharge box body 441 and folding outward at a set angle (such as Figure 7 ).

[0029] For the same purpose, analogous to the above-mentioned front discharge box 44, the rear discharge box 45 is preferably a sheet metal bending part, and it includes a rear discharge box body 451, a rear bottom connection part 452 and a rear side connection part 453. The rear bottom connection part 452 is detachably connected to the base 11 by means of a screw assembly, and includes a first rear bottom connection part formed by the left side wall of the rear discharge box body 451 continuing to extend downward and folding outward 90°, and a second rear bottom connection part formed by the right side wall of the rear discharge box body 451 continuing to extend downward and folding outward 90°. The rear side 453 connection part is also detachably connected to the rear side wall of the protective cabin 12 by means of a screw assembly, and it is formed by the rear side wall of the rear discharge box body 451 continuing to extend forward and folding outward 90° (such as Figure 8 ).

[0030] Of course, the rear material discharging box 45 can also be in a "trumpet-shaped" structure, and also includes a first rear material baffle plate 454 and a second rear material baffle plate 455. The first rear material baffle plate 454 is formed by continuing to extend backward from the left side wall of the rear material discharging box body 451 and folding outward at a set angle. The second rear material baffle plate 455 is formed by continuing to extend backward from the right side wall of the rear material discharging box body 451 and folding outward at a set angle (such as Figure 8 ).

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
