Abstract
Description
Technical Field
[0001] This utility model relates to the field of easy-open lid detection technology, specifically a light leakage detection device for opening easy-open can lids. Background Technology
[0002] With the advancement of technology and the rapid development of various technologies, competition in the easy-open can industry is becoming increasingly fierce. Production lines are operating at ever-faster speeds, and products are becoming increasingly sophisticated. Ordinary easy-open cans can no longer meet customer needs; customers require increasingly refined products. Along with the rise of environmentally friendly products, easy-open cans are also moving towards environmental friendliness. SOT environmentally friendly aluminum alloy can lids are widely used in beverage packaging.
[0003] Currently, before sealing aluminum cans, a seal test is usually performed to prevent leakage after beverages are filled. Light leakage detection is a common method; however, because aluminum cans are cylindrical, conventional light leakage detection devices cannot quickly and thoroughly inspect the can surface, reducing the efficiency of light leakage detection. Therefore, a light leakage detection device for aluminum cans with open lids is proposed. Utility Model Content

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1-3 This utility model provides a technical solution: a light leakage detection device for opening an easy-open can, including a fixed base 1, a detection head 2, a lifting cylinder 3, and a light source 4. A detection chamber 5 is fixedly connected to the surface of the fixed base 1. An inlet 6 and an outlet 7 are respectively opened on the left and right sides of the detection chamber 5. The detection head 2 and the light source 4 are both located inside the detection chamber 5. The upper end of the detection head 2 is fixedly connected to the lifting cylinder 3, and the upper end of the lifting cylinder 3 is fixedly connected to the inner wall of the detection chamber 5. A photoelectric sensor 8 is fixedly connected inside the detection head 2. A sealing head 9 is provided at the lower end of the detection head 2. The light source 4 is located on the periphery of the detection head 2 and is fixedly connected to the detection head 2. A support frame 10 is provided between the light source 4 and the detection head 2.
[0022] In a further improvement, the support frame 10 is arranged in a conical shape, and the light source 4 is fixedly connected to the inner surface of the support frame 10. By providing a conical support frame 10, the light source 4 can be evenly distributed in a ring, which facilitates the full inspection of the side wall of the can.
[0023] In a further improvement, the light source 4 is composed of an aluminum substrate 11 and a number of LED beads 12. The LED beads 12 are uniformly welded to the surface of the aluminum substrate 11. By providing uniformly distributed LED beads 12 on the surface of the aluminum substrate 11, it is convenient to uniformly illuminate the surface of the can, and at the same time, it is convenient for the LED beads 12 to dissipate heat.
[0024] In a further improvement, a fixed frame 13 and a movable frame 14 are provided on the outer side of the lifting cylinder 3. The fixed frame 13 and the movable frame 14 are fixedly connected to both ends of the lifting cylinder 3, and the fixed frame 13 and the movable frame 14 are slidably connected. By providing a fixed frame 13 and a movable frame 14 on the outer side wall of the lifting cylinder 3, the stability of the lifting of the detection head 2 is improved.
[0025] In a further improvement, a ring of guide posts 15 are fixedly connected to the edge of the movable frame 14. The guide posts 15 are slidably connected to the fixed seat 1. By providing guide posts 15 at the edge of the movable frame 14, the connection rigidity between the movable frame 14 and the fixed seat 1 is improved, and shaking during the lifting and lowering of the detection head 2 is avoided.
[0026] Specifically, the sealing head 9 is provided with a sealing skirt 16 at its edge and a focusing lens 17 at its center. By providing a sealing skirt 16 at the edge of the sealing head 9, the sealing performance between the sealing head 9 and the can port is improved, preventing light leakage at the edge. By providing a focusing lens 17 at the center of the sealing head 9, the light can be focused onto the photoelectric sensor 8, improving the detection accuracy.
[0027] In use, the detection device is fixedly installed on the production line using the fixed base 1. Under the action of the conveyor belt, the cans are fed into the detection chamber 5 one by one. The lifting cylinder 3 moves up and down in conjunction with the controller, and the detection head 2 is fastened to the edge of the can. The light source 4 illuminates the outer wall of the can. When there are micropores or cracks in the side wall of the can, the light will enter the interior of the can and be focused by the focusing lens 17 to the photoelectric sensor 8, thereby completing the light leakage detection of the can.
[0028] The problem solved by this invention is that before sealing aluminum cans, a sealing test is usually performed to prevent leakage after beverages are filled. Light leakage detection is a common detection method. However, because aluminum cans are cylindrical, conventional light leakage detection devices cannot quickly and fully detect the surface of the can, reducing the efficiency of light leakage detection. This invention consists of a fixed base 1, a detection head 2, a lifting cylinder 3, and a light source 4 to form a light leakage detection device. The lifting cylinder 3 drives the detection head 2 to move up and down, making it easy to attach the detection head 2 to the surface of the aluminum can. With the light source 4 distributed in a ring on the side wall of the detection head 2, it is convenient to detect light leakage on the surface of the aluminum can, avoiding micropores or cracks on the side wall of the aluminum can, improving the efficiency of light leakage detection and improving the stability of production and processing.
