Description

Technical Field

[0001] This utility model belongs to the technical field of bottle cap inner plug detection equipment, and in particular relates to a device for detecting appearance defects of bottle cap inner plugs. Background Technology

[0002] After the inner stoppers of baijiu (Chinese liquor) bottle caps are injection molded, they need to be inspected for defects such as deformation, flash, black spots, impurities, hair, missing parts, oil stains, and cracks. The types of defects are numerous, therefore, a device is needed to perform comprehensive visual inspection of the inner stoppers to improve product quality and help companies gain a competitive edge in the industry.

[0003] Currently, the inspection method usually involves manual visual inspection. Because the defects of the inspected items are very small, people often miss them, resulting in rework and re-inspection, which causes losses to enterprises. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting defects in the appearance of bottle cap inner plugs, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a device for detecting appearance defects of the inner plug of a bottle cap, comprising:

[0006] Workbench;

[0007] A feeding line is connected to the worktable, and the feeding line is used to continuously feed the inner plug onto the worktable;

[0008] A side detection component is mounted on the worktable for side-view photographic detection of the inner plug.

[0009] A turntable, rotating on the worktable;

[0010] On the workbench, an upper opening detection component, an upper skirt detection component, a lower opening detection component, and a lower skirt detection component are arranged in sequence around the outside of the turntable. These components are used to perform upper opening photographic detection, upper skirt photographic detection, lower opening photographic detection, and lower skirt photographic detection on the inner plug, respectively.

[0011] The discharge assembly line connects to the turntable and is used to unload qualified inner plugs.

[0012] In a further embodiment of this invention, the workbench is provided with a feeding channel that connects the feeding line and the turntable, and the side detection component is located on the side of the feeding channel.

[0013] In a further embodiment of this utility model, the side detection component is provided in two pairs. The side detection components of each pair are respectively provided on both sides of the feed channel and are staggered and opposite to each other. The side detection components are obliquely arranged between the side detection components and the feed channel, and the two pairs of side detection components are symmetrical about the center line.

[0014] In a further embodiment of this invention, the turntable is a transparent glass turntable.

[0015] In a further embodiment of this invention, a discharge channel is provided between the turntable and the discharge production line.

[0016] In a further embodiment of this utility model, an NG material box is provided on one side of the workbench located at the end of the feed channel, and an NG material box is provided on the outer side of the turntable.

[0017] In a further embodiment of this invention, the side detection component, the upper opening detection component, the upper skirt detection component, the lower opening detection component, and the lower skirt detection component are all CCD cameras.

[0018] The beneficial effects of this utility model are:

[0019] As products are fed into the feeding line and continuously conveyed through the feeding channel, the side inspection component performs visual inspection by taking photos of the products to check for defects in the side appearance of the inner plug. Defective products enter the NG box, while qualified products enter the turntable and undergo sequential processes such as upper opening position inspection, upper skirt position inspection, lower opening position inspection, and lower skirt and inner opening position inspection. Defective products enter the NG box, while qualified products exit the discharge channel into the discharge line. The inspection process is highly stable, accurate, and improves inspection efficiency. Attached Figure Description

[0026] like Figure 1 This embodiment provides a device for detecting appearance defects in the inner plug of a bottle cap, comprising:

[0027] Workbench 1;

[0028] Feed line 2 is connected to workbench 1. Feed line 2 is used to continuously feed the inner plugs to workbench 1. Workbench 1 is also provided with feed channel 3, which is connected to feed line 2. Feed channel 3 can be set to be inclined or a vibrating plate can be added. The inner plugs fed from feed line 2 slide down from feed channel 3 in sequence.

[0029] Side detection component 4 is set on the workbench 1 and located on the side of the feed channel 3 for side-view photography detection of the inner plug. There are two pairs of side detection components 4. Each pair of side detection components 4 is set on both sides of the feed channel 3 and is staggered and opposite to each other. The side detection components 4 are obliquely arranged with the feed channel 3. The two pairs of side detection components 4 are symmetrical about the center line. By using multiple sets of side detection components 4, the side of the inner plug is photographed and detected from all directions to ensure that the detection is in place.

[0030] Turntable 5 is rotatably mounted on workbench 1, and feed channel 3 is connected to turntable 5. Turntable 5 is a transparent glass turntable.

[0031] Furthermore, on the workbench 1, an upper opening detection component 6, an upper skirt detection component 7, a lower opening detection component 8, and a lower skirt detection component 9 are arranged sequentially around the outside of the turntable 5. These components are used to perform upper opening photographic detection, upper skirt photographic detection, lower opening photographic detection, and lower skirt photographic detection on the inner plug, respectively. The side detection component 4, upper opening detection component 6, upper skirt detection component 7, lower opening detection component 8, and lower skirt detection component 9 are all CCD cameras. The detection principle of this type of camera is existing, and how to perform detection and photography is also existing. This solution will not elaborate on these points.

[0032] The discharge line 10 connects to the turntable 5 for unloading qualified inner plugs. A discharge channel 11 connects the turntable 5 and the discharge line 10. An NG (Not Good) box 12 is located on one side of the workbench 1 at the end of the feed channel 3, and another NG box 12 is located on the outside of the turntable 5 to collect defective products. Qualified products proceed to the next inspection process. As the product is fed from the feed line 2 and continuously conveyed through the feed channel 3, the side inspection component 4 performs a rapid visual inspection of the product to check for defects on the side appearance of the inner plug. Defective products enter the NG box 12, while qualified products enter the turntable 5. Sequential inspections are performed on the upper opening position, upper skirt position, lower opening position, and lower skirt and inner opening position. Defective products enter the NG box 12, while qualified products exit through the discharge channel 11 into the discharge line 10. This process offers high stability, high accuracy, and improved inspection efficiency.

[0033] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
