DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 7 As shown, a glass bottle mouth micro-crack detection device includes a frame 1. A connecting frame 11 is mounted on the frame 1, and a conveyor line 2 passing through the connecting frame 11 is connected to the frame 1. In detail, a mounting frame 12 is movably mounted on the connecting frame 11, and a visual inspection component 3 is arranged on the mounting frame 12 along the conveyor line 2. During the inspection, the glass bottle to be inspected passes through the connecting frame 11 under the transmission of the conveyor line 2, and the visual inspection component 3 completes the photographing inspection of the glass bottle.

[0026] The visual inspection component 3 includes a pyramid visual module 4, an annular shadowless light visual module 5, a front wall transverse crack visual module 6, a left light visual module 7, a right light visual module 8, and a rear wall transverse crack visual module 9. Among them, the pyramid visual module 4 can shoot and inspect the top of the bottle mouth from top to bottom, the annular shadowless light visual module 5 can shoot and inspect both sides of the bottle mouth, the front wall transverse crack visual module 6 can shoot and inspect the front end face of the bottle mouth, the left light visual module 7 can shoot and inspect the left side face of the bottle mouth, the right light visual module 8 can shoot and inspect the right side face of the bottle mouth, and the rear wall transverse crack visual module 9 can shoot and inspect the rear end face of the bottle mouth. Therefore, the above-mentioned visual modules can cooperate to perform circumferential shooting and inspection of the top, front end face, left side face, rear end face and right side face of the bottle mouth without blind spots.

[0027] It can be understood that although the above-mentioned visual inspection component 3 is adapted to be installed on a liftable mounting frame 12, which makes the present disclosure applicable to the needs of photographing and inspecting glass bottles of different height specifications, in a possible example, the visual inspection component 3 can also be installed in a fixed posture on the frame 1 for photographing and inspecting bottles within a narrower height range.

[0028] In a preferred example, a waste kicking mechanism 10 is connected to the end of the conveyor line 2. For example, the waste kicking mechanism 10 includes a blow pipe 21, and the blow pipe 21 is adapted with a blow port on one side of the conveyor line 2. When an unqualified bottle body is detected by the visual inspection component 3 and is opposite to the blow pipe 21, positive pressure gas can be introduced into the blow pipe 21, and then the gas ejected from the blow port can push the unqualified bottle body away from the conveyor line 2 to avoid flowing into the next process. As another solution, the waste kicking mechanism 10 can also be a push-out mechanism such as a cylinder or an electric cylinder.

[0029] like Figure 4 As shown, in some embodiments, the pyramid vision module 4 includes two first light sources 13 disposed on both sides of the conveyor line 2 and a pyramid camera unit 14 disposed on the top of the conveyor line 2. The pyramid camera unit 14 is a prior art. In simple terms, it includes a camera at the top and a reflector in a housing. For example, the reflector can reflect the light path twice, thereby realizing the camera's shooting detection of the bottle mouth in four directions. That is, the pyramid vision module 4 can realize multi-directional detection of one camera position, for example, it can detect oil spots and defects on the bottle mouth.

[0030] like Figure 5 As shown, the annular shadowless light vision module 5 includes two prism imaging units 15 disposed on both sides of the conveyor line 2 and an annular light source 16 disposed on the top of the conveyor line 2, and the prism imaging unit 15 includes a prism disposed on one side close to the conveyor line 2 and a camera disposed on the side away from the conveyor line 2. The annular light source 16 can be used to illuminate the bottle mouth in an annular manner, and each prism imaging unit 15 can, for example, realize shooting in two directions under the action of the prism, thereby realizing shooting detection of the entire bottle mouth, for example, large cracks at the bottleneck of the bottle mouth can be detected.

[0031] The front wall transverse crack visual module 6 and the rear wall transverse crack visual module 9 have similar structures, and the difference is only in the shooting direction. The following is a detailed introduction based on the definition of the transverse crack visual module:

[0032] like Figure 6As shown, the transverse crack vision module includes a plurality of tilted camera units 17 and a second light source 18 disposed at the top of the conveyor line 2. The tilted camera unit 17 is adapted to tilt the camera unit 17 toward one side of the end face of the bottle mouth. In other words, the front wall transverse crack vision module 6 can take pictures and detect the front end face of the bottle mouth in a tilted posture, and the rear wall transverse crack vision module 9 can take pictures and detect the rear end face of the bottle mouth in a tilted posture. In the specific detection process, most of the light from the second light source 18 passes through the uniform medium of the bottle mouth. If there is a crack, the light will reflect at the crack, thereby detecting the crack at the bottle mouth.

[0033] The left side light vision module 7 and the right side light vision module 8 have similar structures, and the difference is only in the shooting direction. The following is a detailed introduction based on the definition of side light vision module:

[0034] like Figure 7 As shown, the surface light vision module includes a third light source 19 and a side camera unit 20 respectively arranged on both sides of the conveyor line 2. The side camera unit 20 is adapted to shoot to the side of the bottle mouth. That is to say, the side camera unit 20 in the left surface light vision module 7 can shoot and detect the left side of the bottle mouth, and the side camera unit 20 in the right surface light vision module 8 can shoot and detect the right side of the bottle mouth. In the specific detection process, most of the light from the third light source 19 passes through the uniform medium of the bottle mouth. If there is a crack, the light will generate reflection at the crack, so as to detect the crack at the bottle mouth.

[0035] In some embodiments, the connecting frame 11 may include connecting units 23 disposed on both sides of the conveyor line 2, and a plurality of screw lifting mechanisms 22 are disposed on the crossbeam of each connecting unit 23. The mounting frame 12 includes a mounting plate 24 connected to the transfer ends of the plurality of screw lifting mechanisms 22, and the visual module is suspended on the bottom surface of the mounting plate 24 through a connecting rod 25. For example, the screws of the plurality of screw lifting mechanisms 22 are synchronously rotated through a chain (not shown), so that no matter which side the screws of the screw lifting mechanisms 22 are rotated, all the screws will rotate, thereby driving the mounting plate 24 to achieve lifting action.

[0036] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
