Description

Technical Field

[0001] This utility model relates to the field of easy-open lid detection technology, specifically an image detection device for SOE easy-open lids. Background Technology

[0002] Easy-open lids are sealing and opening devices used for metal cans or aluminum cans. They achieve convenient opening through a pre-made embossed structure while ensuring safety during transportation and storage. Easy-open lids are pre-etched with etched lines and riveted with pull rings. They are torn open along the etched lines. Canned products equipped with easy-open lids need to be inspected after production to determine if the easy-open lids are intact.

[0003] However, existing methods for inspecting easy-open canned products have the following problems: They primarily rely on image inspection equipment to process images of the conveyed canned product's easy-open lids. This image is captured and compared to a database; any anomalies indicate a problem. However, in actual use, minute gaps on the lid's surface may go undetected. Therefore, a corresponding technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an image detection device for SOE easy-open lids, which solves the technical problem of mainly using image detection equipment to perform image detection processing on the easy-open lids of transported canned products. The image detection equipment acquires images of the appearance of the easy-open lid and compares them with a database. If there is an anomaly, it indicates that there is a problem with the easy-open lid. However, in actual use, when there are tiny gaps on the surface of the easy-open lid, they may not be detected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SOE easy-open cover image detection device, comprising a conveyor one, a conveyor two, an outer cover, an image detection component, an airtight mechanism, and a separation mechanism. The conveyor one has a separation port in its middle. One end of the conveyor two is connected to the separation port, and a storage container is located directly below the other end. The outer cover is fixed to the middle of the conveyor one and has a detection cavity formed inside. The image detection component, airtight mechanism, and separation mechanism are evenly distributed on the outer cover from right to left. The image detection component includes an image detection camera and a control console connected to the image detection camera via a wiring connection. The detection end of the image detection camera faces downward and is directly opposite the detection chamber. The airtight mechanism includes a mounting cylinder, a column, an electric push rod, a detection plate, an air supply pipe, and an air storage tank. The mounting cylinder is vertically mounted on the outer cover. The column is divided into two sets and symmetrically fixed to the top of the mounting cylinder. The upper end of the column is connected to the electric push rod. The power output end of the electric push rod passes through the mounting cylinder and the lower end is connected to the detection plate. One end of the air supply pipe is connected to the detection plate and the other end is connected to the air storage tank. The separation mechanism includes a hydraulic cylinder and a connecting rod installed at the power output end of the hydraulic cylinder. A push plate is fixed to the outer end of the connecting rod, and the push plate is directly opposite the separation port.

[0006] In a preferred embodiment of this invention, the image detection component, the airtight mechanism, and the separation mechanism are all equipped with infrared sensors, which are connected to the control console via wiring.

[0007] In a preferred embodiment of this utility model, the detection disc includes a disc body with an internal cavity and a sealing ring fixed at the lower opening of the disc body. A pressure sensor is embedded in the inner wall of the internal cavity, and the sealing ring is made of rubber material.

[0008] In a preferred embodiment of this invention, the diameter of the inner cavity is larger than the diameter of the easy-open cover, and the diameter of the sealing ring is equal to the diameter of the easy-open cover, and the two are used in combination.

[0009] In a preferred embodiment of this utility model, the push plate has an arc-shaped structure and is horizontally arranged in the detection cavity, and the width of the push plate is greater than the diameter of the easy-open cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the structure of the existing easy-open lid image detection device. The detection device first acquires an image of the easy-open lid through the image detection component. After the detection is completed, the easy-open lid can be subjected to contact air injection through the subsequent air detection mechanism. By observing the changes in internal air pressure, it can determine whether there are any small gaps, thereby improving the accuracy of the detection. When the detection is completed, if there is a problem with the easy-open lid, the problematic product is separated by the separation mechanism at the tail, thereby achieving the purpose of automated and efficient detection of easy-open lids.

[0012] 2. The detection device designed in this utility model includes two methods: image detection and airtightness detection, which can effectively improve the detection effect of easy-open lids. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: an image detection device for an SOE easy-open lid, including a conveyor 1, a conveyor 2, an outer cover 3, an image detection component, an airtight mechanism, and a separation mechanism. A separation port 4 is provided in the middle of the conveyor 1. One end of the conveyor 2 is connected to the separation port 4, and a storage container 5 is located directly below the other end. The outer cover 3 is fixed to the middle of the conveyor 1 and has a detection cavity 6 formed inside. The image detection component, airtight mechanism, and separation mechanism are evenly distributed on the outer cover 3 from right to left. The image detection component includes an image detection camera 7 and a control console 8 connected to the image detection camera 7 via a wiring connection. The detection end of the image detection camera 7 faces downwards. Facing the detection chamber 6, the airtight mechanism includes a mounting cylinder 9, a column 10, an electric push rod 11, a detection plate 12, an air supply pipe 13, and an air storage tank 14. The mounting cylinder 9 is vertically mounted on the outer cover 3. The column 10 is divided into two sets and symmetrically fixed to the top of the mounting cylinder 9. The upper end of the column 10 is connected to the electric push rod 11. The power output end of the electric push rod 11 passes through the mounting cylinder 9 and the lower end is connected to the detection plate 12. One end of the air supply pipe 13 is connected to the detection plate 12 and the other end is connected to the air storage tank 14. The separation mechanism includes a hydraulic cylinder 15 and a connecting rod 16 installed at the power output end of the hydraulic cylinder 15. A push plate 17 is fixed to the outer end of the connecting rod 16, and the push plate 17 faces the separation port 4.

[0020] Further improvements, such as Figure 1 As shown, the image detection component, the airtight mechanism, and the separation mechanism are all equipped with infrared sensors 18. The infrared sensors 18 are connected to the control console 8 via lines and can detect the position of the easy-open cover.

[0021] Further improvements, such as Figure 3 As shown, the detection disc 12 includes a disc body 20 with an inner cavity 19 and a sealing ring 21 fixed at the lower opening of the disc body 20. An air pressure sensor 22, which is an MS5611 air pressure sensor, is embedded in the inner wall of the inner cavity 19. The sealing ring 21 is made of rubber material. The detection disc 12 is sealed and connected to the easy-open cover and passes gas through it. The air pressure sensor 22 detects the internal pressure and observes the pressure change.

[0022] Further improvements, such as Figure 3 As shown, the diameter of the inner cavity 19 is larger than the diameter of the easy-open lid, and the diameter of the sealing ring 21 is equal to the diameter of the easy-open lid. The two work together. This design makes it easy to seal the easy-open lid at the top of the can by the sealing ring 21 and allow gas to be introduced to observe the internal pressure changes.

[0023] Specifically, the push plate 17 has an arc-shaped structure and is horizontally set in the detection cavity 6. The width of the push plate 17 is greater than the diameter of the easy-open cover. This design makes it easy to separate the substandard easy-open covers and guide them onto the conveyor 2.

[0024] In use: Conveyor 1 transports canned products equipped with easy-open lids. When the product moves to the area below the image detection component, infrared sensor 18 detects the product and transmits the signal to control console 8. Control console 8 controls image detection camera 7 to acquire an image of the easy-open lid and compare it with the shape of the easy-open lid in the database to determine if there is a difference. If there is a difference, it indicates a problem. After image detection is completed, the canned product continues to move to the area directly below the airtight mechanism. Electric push rod 11 pushes the detection disc 12 to move longitudinally, causing the sealing ring 21 of the detection disc 12 to seal with the edge of the easy-open lid. During docking, gas from the gas storage tank 14 is introduced into the easy-open lid through the gas supply pipe 13. After the gas supply is completed, the value of the pressure sensor 22 is observed. If the value is not normal, it means that there is no airtightness problem. Otherwise, it means that there is an airtightness problem with the easy-open lid. The easy-open lid is inspected for image and airtightness by the image detection component and the airtightness mechanism. If one or more of the inspections fail, the control console 8 controls the operation of the separation mechanism. The hydraulic cylinder 15 pushes the push plate 17 to move laterally and separates the canned products with the problematic easy-open lids, which are then introduced into the conveyor 2, achieving the purpose of automated inspection and selection.
