Description

Technical Field

[0001] The utility model relates to the field of beverage can quality inspection equipment, in particular to beverage can defect inspection equipment. Background Art

[0002] Beverage can defect detection is an important production process in the beverage can processing process. The key is to identify and eliminate defective products in the production process. The detection process needs to be specific to different parts of the glass bottle. There are multiple items that need to be tested, such as the bottle mouth and the bottle body. The inspection of the bottle mouth includes whether there are gaps, crack defects, gaps, breaks, uneven round mouths, etc. on the surface. The inspection of the bottle body includes bubbles, impurities, wrinkles, horizontal and vertical stripes, adhesions, stones, cracks, scratches, abrasions, and obvious oil stains and fingerprints.

[0003] Most of the existing inspection processes for the body of beverage cans use multi-angle photography inspection, using four cameras at 90° to inspect the side wall of the bottle cap. This inspection method involves a large number of cameras. When processing data and determining defects later, it is necessary to refer to the image data of the four cameras. If the placement of the beverage can is offset, the visual inspection process of multiple cameras is prone to deviation. Therefore, in the process of inspecting the body of multiple beverage cans in the assembly line, this inspection method is prone to detection errors, which reduces the inspection efficiency.

DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1 , Figure 2 and Figure 3 The beverage can defect detection device shown in the figure comprises a rotating seat 1 and a positioning protrusion 2 which can rotate synchronously with the rotating seat 1. A pressing block 3 which can rotate synchronously with the positioning protrusion 2 is arranged directly above the positioning protrusion 2. The pressing block 3 and the positioning protrusion 2 can respectively abut against the upper and lower surfaces of the beverage can. When the rotating seat 1 rotates, the pressing block 3 and the positioning protrusion 2 can clamp the beverage can and rotate.

[0025] A top plate 4 is provided above the pressing block 3, on which a liftable linkage arm 5 is provided, and on which a positioning seat 6 for storing the linkage arm is provided. When the linkage arm 5 moves up and down along the distribution direction of the positioning seat 6, the pressing block 3 moves synchronously, and on the positioning seat 6 an industrial camera 7 is provided. The industrial camera 7 performs continuous visual inspection operations on the beverage cans in a rotating state, converts the images into digital signals, and then transmits the images to a processing device, which refers to the image data to determine whether there are defects on the bottle of the beverage can.

[0026] Through this detection method, as the beverage can rotates, the efficiency of the detection work is improved, so that the flange parts at the upper and lower ends of the beverage can can be fully exposed, thereby improving the comprehensiveness and accuracy of the detection work.

[0027] like Figure 4 , Figure 5 As shown, in order to enable the pressing block 3 and the positioning protrusion 2 to clamp the beverage can and rotate, and to prevent the beverage can from getting stuck after being clamped by the pressing block 3 and the positioning protrusion 2, a linkage rod 31 coaxially distributed therewith is provided below the top plate 4, a docking sleeve 32 is connected to the linkage rod 31 through a bearing, and the outer side of the docking sleeve 32 is connected to the pressing block 3 through a plurality of equally distributed connecting arms 33, and when the pressing block 3 rotates, the connecting sleeve 32 and the connecting arms 33 rotate with the linkage rod 31 as the central axis.

[0028] like Figure 4 , Figure 5 As shown, the middle axis of the top plate 4 is provided with a guide column 41, which is connected to the linkage rod 31 through a pressure spring 42, and the linkage rod 31, the docking sleeve 32, the connecting arm 33 and the pressing block 3 can slide along the distribution direction of the guide column 41. After the pressing block 3 abuts against the beverage can as the top plate 4 descends, the pressure from the top plate 4 can be buffered, effectively preventing the top plate 4 and the pressing block 3 from applying excessive pressure to the top of the beverage can, causing deformation of the top of the can body.

[0029] Furthermore, since the distance between the pressing block 3 and the top plate 4 can be flexibly adjusted, the pressing block 3 and the positioning protrusion 2 can abut against the upper and lower surfaces of beverage cans of different specifications. When the rotating seat 1 moves, the beverage can is driven to move, and the industrial camera 7 performs defect detection operations on it, thereby improving the application range of the entire device.

[0030] like Figure 4 As shown, a boss is provided on the alignment seat 6, and a cylinder 8 is provided on the boss, and the output end of the cylinder 8 is connected to the linkage arm 5. When the cylinder 8 is in operation, it can drive the linkage arm 5 to move up and down, so as to achieve the purpose of driving the top plate 4 to descend and the pressing block 3 to abut against the surface of the beverage can.

[0031] like Figure 1 As shown, the linkage arm 5 extends to the inner side of the alignment seat 6, and the inner side of the alignment seat 6 is provided with a horizontally distributed limiting column 61, and the surface of the linkage arm 5 is provided with a channel that can accommodate the limiting column 61. When the linkage arm 5 moves, the channel adjusts its position along the distribution direction of the alignment seat 6, ensuring the linearity of the linkage arm 5 during the movement process.

[0032] like Figure 4 As shown, in order to ensure the stability of the rotating seat 1 , a base 9 is provided on the alignment seat 6 , and the base 9 is located directly below the rotating seat 1 .

[0033] like Figure 4As shown, in order to drive the rotating seat 1 to rotate smoothly, a driving motor 10 is provided on the inner side of the base 9, and a linkage gear 1 11 is installed on the main shaft of the driving motor 10. When the driving motor 10 is in operation, the linkage gear 1 11 can be driven to rotate. The linkage gear 1 11 is installed on the inner wall of the base 9, and the linkage gear 1 11 is meshed and connected with the linkage gear 2 12. The linkage gear 2 12 is coaxially distributed with the rotating seat 1, and the linkage gear 2 12 is connected to the rotating seat 1 through the driving shaft 13. The rotation of the linkage gear 1 11 can smoothly drive the linkage gear 2 12 to rotate, and under the connection of the driving shaft 13, the rotating seat 1 can be smoothly driven to rotate.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
