Description

Technical Field

[0001] The utility model relates to the field of visual inspection of packaging boxes, in particular to a device for inspecting damaged and broken films of packaging boxes. Background Art

[0002] The visual inspection equipment for damaged plastic film packaging bags is an efficient inspection tool that uses machine vision technology. It uses high-resolution cameras and image processing systems to scan and identify damage on packaging bags, such as cracks and holes, in real time, and automatically classify, record and process unqualified products. The equipment is widely used in production lines in the food, pharmaceutical, chemical and other packaging industries. With its high precision, high efficiency and stability, it provides companies with an important means of quality control, ensuring the safety and integrity of product packaging. The introduction of this equipment not only improves the level of automation in product quality inspection, but also significantly improves production efficiency and reduces costs.

[0003] The current quality inspection of the external film packaging of cosmetics uses CCD visual inspection technology to screen defective products. The working process is as follows: the cosmetics are transported by a conveyor belt, and the CCD visual inspection system on the top performs a detailed inspection of the film on the outer surface of the cosmetics. Once a defective product is detected, the system will start the cylinder on one side to push the cosmetic box for removal. However, there are some problems in the removal process. Due to the friction between the cosmetic box and the conveyor belt, and the influence of the conveyor belt movement, the cosmetic box itself will produce a certain inertia. This traditional cylinder-pushing removal method will cause the cosmetic box's flying path to deviate from the straight line. The cosmetics' flying path is affected by many factors, including the conveyor belt's transportation speed, surface friction, and the cylinder's telescopic speed. The combined effect of these factors makes the cosmetics' flying path inconsistent after removal, which increases the difficulty of collecting defective cosmetic boxes. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a device for detecting damaged and broken film of packaging boxes, so as to solve the technical problem that the flying path of cosmetics is affected by factors such as the transportation speed of the conveyor belt, the friction of the surface, the extension and retraction speed of the cylinder, etc. If any of these factors changes, the flying path of the cosmetic box may be changed, resulting in greater difficulty in collecting defective cosmetic boxes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for detecting damaged and broken film of packaging boxes, comprising a frame and a main conveyor belt, a receiving mechanism is provided on one side of the frame, the receiving mechanism comprises a mounting seat, a receiving plate is slidably connected to the mounting seat through a slide groove and a slider, and side panels are provided on both sides of the receiving plate.

[0006] By adopting the above technical solution and using the slide groove and slider to adjust the lateral position of the receiving plate, it can be ensured that the receiving plate and the side plate are accurately moved to the simulated flying path of the packaging box. This setting improves the adaptability of the equipment to different flying paths, and can effectively receive the rejected packaging boxes regardless of the transmission speed or usage environment.

[0007] Furthermore, wide-mouth side panels are provided on both sides of the end of the receiving plate, and a top plate is provided above the end of the receiving plate.

[0008] By adopting the above technical solution, the wide-mouth side panels on both sides of the receiving plate end can effectively guide the rejected packaging boxes into the receiving area to prevent them from deviating from the predetermined path. The wide-mouth setting increases the tolerance rate of the packaging boxes entering the receiving range, ensuring that the packaging boxes can fall smoothly into the receiving frame.

[0009] Furthermore, the wide-mouth side panels, the receiving panels and the top panel are shaped like trumpet structures, and a receiving frame is provided below the end of the receiving panel.

[0010] By adopting the above technical solution, the opening of the receiving area can be effectively enlarged to provide a wider entry channel for the rejected packaging boxes. Such a setting makes it easier for the packaging boxes to be accurately guided into the receiving area, thereby improving the collection efficiency.

[0011] Furthermore, the mounting seat is a rectangular strip structure and is detachable from the frame.

[0012] By adopting the above technical solution, the mounting seat is configured as a rectangular strip structure, which is stable and easy to install, so that the receiving mechanism can be stably mounted on the frame, ensuring the stability and reliability of the packaging box rejection and collection process.

[0013] Furthermore, a secondary conveyor belt is provided at the end of the main conveyor belt for docking and transporting the packaging box to the next processing procedure.

[0014] By adopting the above technical solution, continuous transportation of packaging boxes is achieved to ensure smooth production process. This setting eliminates the need for manual intervention when transferring packaging boxes from the main conveyor belt to the auxiliary conveyor belt, thereby improving the degree of automation.

[0015] Furthermore, a support frame is arranged above the main conveyor belt, and a CCD detection mechanism is arranged on the inner side of the support frame.

[0016] By adopting the above technical solution, a stable installation position is provided for the CCD detection mechanism, ensuring that it can accurately detect each passing packaging box. This layout makes the detection process more efficient and accurate.

[0017] Furthermore, a fill light is provided on one side of the support frame, and two limit plates are provided on one side of the top of the main conveyor belt.

[0018] By adopting the above technical solution, the fill light provides sufficient and uniform light for the CCD detection mechanism, ensuring that clear and accurate images can be obtained for the detection of the packaging box under various lighting conditions, which greatly improves the accuracy and reliability of the detection.

[0019] Furthermore, a cylinder is provided on one side of the interior of the frame, and a push plate is provided at the telescopic end of the cylinder.

[0020] By adopting the above technical solution, the cylinder is installed on one side of the inner part of the frame, and the movement of the push plate can be controlled by its telescopic function. This arrangement automates the process of rejecting defective products from the packaging box, greatly improving production efficiency.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model uses a receiving mechanism to adjust the lateral position of the receiving plate through a slide groove and a slider, which can ensure that the receiving plate and the side plate are accurately aligned with the simulated flying path of the packaging box. This setting enables the device to flexibly adjust the receiving position according to the actual flying situation of the packaging box, so as to adapt to different working environments and rejection conditions. At the same time, the accurate docking of the flying path of the packaging box can greatly improve the collection efficiency of defective products, reduce the situation of scattering and misconnection, and make the collection operation more convenient. This adjustment mechanism enhances the adaptability of the equipment to different use environments, whether in high-speed transmission or low-speed transmission, or on the conveyor belt surface with different friction coefficients, it can achieve effective defective product collection;

[0023] 2. The utility model provides wide-mouth side panels and a top panel. The wide-mouth side panels on both sides of the end of the receiving plate can expand the receiving range, making it easier for rejected packaging boxes to enter the receiving area, reducing the failure of packaging boxes to be received due to deviation of the pop-up trajectory. This arrangement enhances the stability and accuracy of packaging box reception. At the same time, the top panel above the end of the receiving plate can prevent the packaging box from popping up from the receiving area due to inertia, ensuring that the packaging box can stably fall into the receiving frame after being rejected. Such a structure not only improves the collection efficiency of defective products, but also ensures the smoothness and safety of the production process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A device for detecting damaged or broken packaging films, such as Figure 1-Figure 4 As shown, it includes a frame 101 and a main conveyor belt 102. A receiving mechanism 8 is arranged on one side of the frame 101. The receiving mechanism 8 includes a mounting seat 801. A receiving plate 804 is slidably connected to the mounting seat 801 through a slide groove 802 and a slider 803. Side plates 805 are arranged on both sides of the receiving plate 804. The lateral position of the receiving plate 804 is adjusted by the slide groove 802 and the slider 803 to ensure that the receiving plate 804 and the side plates 805 are accurately moved to the simulated flying path of the packaging box. Such a setting improves the adaptability of the equipment to different flying paths. No matter what transmission speed or use environment, the rejected packaging boxes can be effectively received. At the same time, due to the flexibility of the position of the receiving plate, the collection of defective products becomes more convenient, reducing the collection difficulties caused by inconsistent flying paths of the packaging boxes. Such adjustment not only improves the environmental applicability of the collection operation, but also significantly improves the efficiency and convenience of collecting defective products.

[0033] See also Figure 1 , Figure 3Wide-mouth side panels 806 are provided on both sides of the end of the receiving plate 804, and a top plate 807 is provided above the end of the receiving plate 804. The wide-mouth side panels 806 on both sides of the end of the receiving plate 804 can effectively guide the rejected packaging boxes into the receiving area to prevent them from deviating from the predetermined path. The wide-mouth setting increases the tolerance rate of the packaging boxes entering the receiving range, ensuring that the packaging boxes can smoothly fall into the receiving frame 9. At the same time, the top plate 807 above the end of the receiving plate 804 plays a role in limiting the packaging boxes from popping up upwards, ensuring that the packaging boxes will not fly out of the receiving area due to inertia when being rejected. Such a structure makes the collection of packaging boxes more stable and reliable, reduces the scattering and damage of defective products, and improves the overall production efficiency and collection effect.

[0034] See also Figure 1 , Figure 3 The wide-mouth side panels 806, the receiving plates 804 and the top plates 807 are shaped like trumpet structures. A receiving frame 9 is provided below the end of the receiving plate 804, which can effectively expand the opening of the receiving area and provide a wider entry channel for the rejected packaging boxes. Such a setting makes it easier for the packaging boxes to be accurately guided into the receiving area, thereby improving the collection efficiency. At the same time, the receiving frame 9 below the end of the receiving plate 804 is used to collect defective packaging boxes that have fallen into the receiving area, thereby ensuring the safe collection of the packaging boxes and preventing the packaging boxes from being scattered and damaged. This structural layout is reasonable and practical, which facilitates the processing and subsequent operations of defective products, thereby improving the efficiency and smoothness of the entire production process.

[0035] See also Figure 1 The mounting seat 801 is a rectangular strip structure and is detachable from the frame 101. The mounting seat 801 is set as a rectangular strip structure. This structure is stable and easy to install, so that the receiving mechanism 8 can be stably installed on the frame 101, ensuring the stability and reliability of the packaging box rejection and collection process. At the same time, a detachable structure is adopted between the mounting seat 801 and the frame 101. This setting facilitates the installation, maintenance and replacement of the equipment. When the receiving mechanism 8 needs to be repaired or replaced, the mounting seat 801 can be quickly removed, thereby improving the maintainability and production efficiency of the equipment.

[0036] See also Figure 1 , Figure 2 A secondary conveyor belt 10 is provided at the end of the main conveyor belt 102, which is used for docking and transporting the packaging box with the next processing procedure, realizing the continuous transportation of the packaging box and ensuring the smooth progress of the production process. This setting makes it possible to transfer the packaging box from the main conveyor belt 102 to the secondary conveyor belt 10 without manual intervention, thereby improving the degree of automation. At the same time, the setting of the secondary conveyor belt 10 also facilitates the docking and transportation of the packaging box with the next processing procedure, reduces the waiting time and labor handling costs in the production process, and improves production efficiency.

[0037] Embodiment 2:

[0038] See also Figure 1 , Figure 4 A support frame 3 is arranged above the main conveyor belt 102, and a CCD detection mechanism 4 is arranged on the inner side of the support frame 3, which provides a stable installation position for the CCD detection mechanism 4 to ensure that it can accurately detect each passing packaging box. This layout makes the detection process more efficient and accurate. At the same time, the CCD detection mechanism 4 is installed on the inner side of the support frame 3, and can accurately perform visual inspection on the film outside the packaging box, and timely discover and identify defective products. This automated detection method not only improves the detection efficiency, but also reduces the cost of manual detection, and provides a strong guarantee for the quality control of the production line.

[0039] See also Figure 1 , Figure 4 A fill light 5 is arranged on one side of the support frame 3, and two limit plates 2 are arranged on one side of the top of the main conveyor belt 102. The fill light 5 provides sufficient and uniform light for the CCD detection mechanism 4, ensuring that under various lighting conditions, the detection of the packaging box can obtain clear and accurate images, which greatly improves the accuracy and reliability of the detection. At the same time, the two limit plates 2 arranged on one side of the top of the main conveyor belt 102 ensure the stability of the packaging box during the transmission process and prevent it from deviating from the predetermined path. This arrangement not only reduces the deviation and overturning of the packaging box during the transmission process, but also ensures that each packaging box can pass through the CCD detection mechanism 4 in the correct position and posture, thereby further improving the accuracy of the detection.

[0040] See also Figure 1 , Figure 2 , Figure 4 A cylinder 6 is provided on one side of the interior of the frame 101, and a push plate 7 is provided on the telescopic end of the cylinder 6. The cylinder 6 is installed on one side of the interior of the frame 101, and the movement of the push plate 7 can be controlled by its telescopic function. This arrangement automates the process of rejecting defective packaging boxes, greatly improving production efficiency. At the same time, the push plate 7 is driven by the cylinder 6, and can quickly and accurately push the detected defective packaging boxes from the main conveyor belt 102 to prevent defective products from entering the next production link. This method of quickly rejecting defective products not only ensures product quality, but also avoids the tediousness and inaccuracy of manual rejection, providing strong support for the efficient operation of the production line.

[0041] The implementation principle of the utility model is as follows: first, the cosmetic packaging box is placed on the end of the main conveyor belt 102, the main conveyor belt 102 is used to transport the packaging box, and the limit plates 2 on both sides are used to limit the moving path of the packaging box, so that the packaging box is moved to the bottom of the support frame 3, and the film on the outside of the packaging box is visually inspected by the CCD detection mechanism 4. If the packaging box is found to be a defective product, the signal is transmitted to the control center, and then the control cylinder 6 is controlled to perform telescopic movement, so that the push plate 7 at the telescopic end applies thrust to the packaging box, and then the packaging box is pushed onto the receiving plate 804, and the inclined receiving plate 804 is used to guide the packaging box, so that the packaging box falls into the inside of the receiving frame 9, completing the collection of defective packaging boxes, and the good products are directly transported to the next processing step through the main conveyor belt 102 and the auxiliary conveyor belt 10.

[0042] Before the packaging box inspection operation, the factors such as the conveying speed of the conveyor belt, the friction between the packaging box and the conveyor belt surface, the extension and retraction speed of the cylinder are taken into consideration, and the rejection and flying path of the simulated packaging box of the test product is simulated. Then, the receiving plate 804 is moved horizontally through the slide groove 802 and the slider 803 until the receiving plate 804 and the side plate 805 slide to the simulated flying path of the packaging box. This is beneficial for collecting the packaging boxes according to the actual use environment, improving the environmental applicability of the collection operation, and improving the convenience of collecting defective products.
