Description

A high-speed liquid foreign object inspection machine Technical Field

[0001] This utility model relates to the field of high-speed liquid foreign object inspection technology, specifically a high-speed liquid foreign object inspection machine. Background Technology

[0002] When filling liquids, automatic filling is generally carried out using filters and a sealed environment to prevent particulate matter from affecting the liquid's transparency and causing poor visual appeal and taste for users. However, foreign matter can still be introduced into the liquid due to various reasons, including foreign objects inside the container itself, foreign objects inside the bottle cap, residue caused by the cap pressing against the bottle opening, residue from a broken filter, air fibers, and insects.

[0003] In the bottling industry for pharmaceuticals, beverages, beer, and spirits, both the containers and the liquids are made of transparent materials. The presence of foreign matter in the liquid can lead to customer complaints. Currently, these bottling industries generally use manual visual inspection and fully automated inspection machines for foreign matter detection. Manual visual inspection involves manually grasping, shaking, or flipping the bottle and observing it in backlight. While simple and convenient, prolonged manual observation causes severe visual and operational fatigue, and human inspection capabilities decline with fatigue. The fully automated inspection machine method uses a rotating bottle with sudden stop and follow-up photography to observe the movement trajectory of foreign matter and thus identify it. Although this method is much faster and more effective than manual inspection, the following mechanism is overly complex and cumbersome. At high speeds, the excessive oscillation inertia of the following mechanism causes violent shaking of the entire inspection equipment, resulting in poor detection results. Therefore, we propose a high-speed liquid foreign matter inspection machine. Summary of the Invention

The picture shows the bottle in a stationary state, with only the liquid inside the bottle rotating, to avoid the bottle... To detect interference such as prints or scratches, the controller in the electrical control box 94 determines whether there are suspended impurities inside the bottle based on whether there are areas in the photos fed back by each camera 2 65 and motor 1 63 that are different from the areas in the photos of the bottle without impurities.

The large pulley 53 drives the intermediate synchronous wheel 59 and the intermediate gear 58 to rotate. The intermediate gear 58 drives the two star gears 56 to rotate, so that the two star disks 57 rotate in opposite directions. The bottle moves to the upper end of the adjacent bottle holder 97 through the star disk 57 on the left. The turntable base plate 91 rotates, and the bottle holder 97 and the bottle pressing seat 96 rotate synchronously, bringing the bottle from the left to the right clockwise. Then the extension end of the cylinder 95 retracts, and the bottle is brought out by the star disk 57 on the right.

[0039] The working principle of the high-speed liquid foreign object inspection machine provided by this utility model is as follows: The output shaft of motor 52 drives the large pulley 53 and drive gear 15 to rotate. The drive gear 15 drives the meshing slewing bearing 16 to rotate inside the slewing bearing seat 14, which in turn drives the entire assembly consisting of turntable base plate 91, turntable support lifting column 92, turntable top support plate 93 and electrical control box 94 to rotate. The large pulley 53 drives the intermediate synchronous pulley 59 and intermediate gear 58 to rotate. The intermediate gear 58 drives the two star gears 56 to rotate, realizing the relative reverse rotation of the two star disks 57. The bottle moves to the upper end of the adjacent bottle holder 97 through the star disk 57 on the left. The telescopic end of the cylinder 95 extends, and the bottle pressing seat 96 presses down on the bottle on the upper end of the bottle holder 97 to fix the bottle. Then the electric... Machine 3 (99) drives synchronous pulley 2 to rotate, which in turn drives synchronous pulley 1 (98) and bottle holder 97 to rotate via synchronous belt 1, achieving bottle rotation. Turntable base plate 91 rotates, and bottle holder 97 and bottle pressure seat 96 rotate synchronously, bringing the bottle clockwise from the left to the right. Then, the extension end of cylinder 95 retracts, and the bottle is pulled out by star plate 57 on the right. The controller of electrical control box 94 is bidirectionally electrically connected to the conductive ring of conductive slip ring 4. The contacts of conductive slip ring 4 maintain contact with the surface of the conductive ring through elastic pressure. When the conductive ring rotates, a dynamic sliding contact is formed between the contacts and the conductive ring, achieving continuous transmission of current or signals. The output shaft of motor 1 (63) drives camera mounting plate 62 to rotate. The maximum rotation angle of camera mounting plate 62 is 60°, which in turn drives camera base 64. Synchronous rotation enables the rotation of motor 63 and camera 65. The camera mounting plate 62 has evenly distributed clearance grooves in its center, with hexagonal guide posts 3 located inside adjacent clearance grooves to prevent interference between the camera mounting plate 62 and the hexagonal guide posts 3 during rotation. The output shaft of motor 71 drives two tracking gears 73 to rotate. The two tracking gears 73 overlap to prevent hairline damage. The two tracking gears 73 drive the arc-shaped rack plate 74 to rotate. The rotation of the arc-shaped rack plate 74 causes the slider of the light source fixing plate 77 and the arc-shaped slide rail 79 to slide on the upper end of the arc-shaped slide rail 79. A PU buffer pad 8 is slidably connected inside the arc-shaped buffer groove to buffer the impact force when the light source fixing plate 77 moves to its maximum angle. A gear protective cover 10 prevents wires from getting caught in the tracking gears 73. The arc-shaped rack plate 74 and the tracked gear 73 rotate and wear. The leftmost set of camera bases 64 is the first station, the two middle sets of camera bases 64 are the second and third stations from left to right, and the rightmost set of camera bases 64 is the fourth station. The arc-shaped light unit 75 corresponds to the position of the adjacent set of camera bases 64 on the inner side. The arc-shaped light unit 75 is also divided into four stations. The second and third stations of the arc-shaped light unit 75 are combined. During detection, when camera two 65 takes pictures of a bottle, the controller of the electrical control box 94 controls the corresponding motor three 99 to stop suddenly. The bottle is in a stationary state in the picture, and only the liquid inside the bottle is rotating, so as to avoid interference from the bottle's prints or scratches. If there are suspended impurities inside the bottle...After the luminous surface of the arc-shaped light unit 75 is illuminated, the suspended matter produces backlighting, and a change in grayscale is observed. The controller in the electrical control box 94 determines whether there are suspended impurities inside the bottle based on whether there are areas in the photos fed back by each camera 2 65 and motor 1 63 that differ from the areas in the photos of the bottle without impurities. The bottom light source 76 at the second station illuminates the bottle upwards, causing darker impurities to cast upward shadows. The third station exchanges the light and dark fields with the second station, mainly detecting foreign objects at the bottom and lower part of the bottle. The fourth station is for enhanced detection. Camera 2 65 is set horizontally, and camera 1 61 is set at an angle downwards (camera 2 65 and camera 1 61 are of the same type but have different shooting angles; camera 1 61 is shooting from above, while camera 2 65 is shooting vertically). Camera 1 61 takes a picture of the bottom of the bottle, enhancing the detection of the bottom edge of the bottle.
