Description

Technical Field

[0001] The utility model relates to a crack detection structure for the body of a relief pattern bottle. Background Art

[0002] With the development of photographing and imaging technology, more and more products can be detected through photographing and imaging, such as printing detection and coding detection. Currently, there are also methods for detecting glass bottles and jars through photographing and imaging, but they are limited to general bottle types with smooth exteriors, such as beer bottles and beverage bottles. Its principle is to image the defects on the surface of the glass bottle through photographing. The images of normal bottles without defects have no shadows and black dots. If there are shadows and black dots, the product is determined to be defective.

[0003] For special-shaped liquor bottles with patterns or reliefs on the outer surface, because the patterns and reliefs will interfere with the detection results during photographing and imaging, this detection technology is not applicable to pattern bottles. With the increasing requirements of each liquor enterprise for product quality and the increasing labor cost, the detection demand of liquor bottle manufacturers for relief pattern bottles is becoming increasingly strong. Content of the Utility Model

[0004] To solve the above technical problems, the utility model proposes a crack detection structure for the body of a relief pattern bottle, providing a feasible photographing and imaging detection scheme for special-shaped wine bottles with patterns or reliefs on the outer surface, meeting the detection requirements of liquor bottle manufacturers for relief pattern bottles, and ensuring product quality.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A crack detection structure for the body of a relief pattern bottle, the structural characteristics of which are:

[0007] The combined inspection machine receives the wine bottles conveyed by the conveying chain plate through a star plate assembly that rotates synchronously around the central axis along with the rotating shaft. The outer wall of the bottle body of the wine bottle has patterns or reliefs. Each wine bottle received by the combined inspection machine is evenly spaced along the circumferential direction in each receiving bayonet of the star plate assembly and makes a circular motion synchronously with the rotation of the star plate assembly. The receiving bayonet penetrates vertically and is a notch formed by concave inward along the radial direction of the star plate assembly from the outer edge of the star plate assembly. The contour is adapted to the outer contour of the bottle body of the wine bottle at the corresponding height position. The wine bottle is received in the receiving bayonet and is exposed on the side facing outward along the radial direction of the star plate assembly, leaving a gap between it and the inner contour of the receiving bayonet;

[0008] The detection station is located on the periphery of the star plate assembly and is provided with a detection light source, a detection camera, and a steering mechanism. The detection light source and the imaging end of the detection camera are respectively directed at the part to be detected of the passing wine bottle. The steering mechanism is a steering wheel rotatably mounted on a column, and the outer edge of the steering wheel can contact the bottle body of the wine bottle on the passing star plate assembly in a tangential manner.

[0009] The structural features of the present utility model also lie in that:

[0010] The star plate assembly of the combined inspection machine includes an upper star plate and a lower star plate which are coaxially and vertically spaced and assembled on a rotating shaft and have the same structure. The notch includes an upper notch on the upper star plate and a lower notch on the lower star plate. The upper notch and the lower notch have the same structure and jointly form the accommodating bayonet. The wine bottle can be adaptively accommodated in the accommodating bayonet and is synchronously displaced with the rotation of the star plate assembly.

[0011] The conveying chain plate is arranged on the outside of one side of the lower star plate parallel to the direction tangent to the lower star plate. At the intersection of the conveying path and the rotation trajectory of the star plate assembly, the star plate assembly sequentially sleevs the bottle body of the wine bottle on the conveying chain plate through each accommodating bayonet with the rotation of the upper star plate and the lower star plate, completing the reception of the wine bottle conveyed by the conveying chain plate. The conveying chain plate conveys from back to front. At the intersection of the rotation trajectory of the star plate assembly and the conveying path of the conveying chain plate, each accommodating bayonet makes a circumferential displacement along the direction from back to front.

[0012] The steering wheel contacts the outer wall of the lower end of the passing wine bottle body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are reflected in that:

[0014] The present utility model uses a detection camera and a detection light source to jointly detect cracks on the bottle body of the wine bottle reaching the detection station. At the same time, a steering mechanism is set, so that the wine bottle at the detection station can realize a certain degree of rotation of itself through contact with the steering mechanism, making the detected range of the bottle body larger. Using the principle that light generates specular reflection at the crack defect, by configuring the detection light source to shine on the wine bottle and configuring the detection camera to receive the reflected light from the wine bottle, through the analysis of the intensity of the received reflected light, it can be used as a basis for judging whether there are crack defects, and the detection is more accurate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1 to 2 , the crack detection structure of the embossed pattern bottle body in this embodiment is set as follows:

[0020] The combined inspection machine receives the wine bottles 11 conveyed by the conveying chain plate 2 through the star plate assembly that rotates synchronously around the central axis with the rotating shaft 1. The outer wall of the bottle body of the wine bottle 11 has patterns or reliefs. The wine bottles 11 received by the combined inspection machine are evenly spaced along the circumferential direction in the respective receiving sockets of the star plate assembly, and move in a circular motion synchronously with the rotation of the star plate assembly. The receiving sockets are vertically through, and are notches formed by concave inward along the radial direction of the star plate assembly from the outer edge of the star plate assembly. The contour is adapted to the outer contour of the bottle body of the wine bottle 11 at the corresponding height position. The wine bottle 11 is received in the receiving socket and is exposed on the side facing outward along the radial direction of the star plate assembly, leaving a gap between it and the inner contour of the receiving socket;

[0021] The detection station is located on the periphery of the star plate assembly, and is provided with a detection light source 7, a detection camera 8, and a steering mechanism. The imaging ends of the detection light source 7 and the detection camera 8 are respectively directed towards the parts to be detected of the passing wine bottle 11. The steering mechanism is a steering wheel 10 rotatably mounted on a column 9, and the outer edge of the steering wheel 10 can contact the bottle body of the wine bottle 11 carried on the passing star plate assembly in a tangential posture.

[0022] In specific implementation, the corresponding structural settings of the above-mentioned crack detection structure of the embossed pattern bottle body also include:

[0023] The star plate assembly of the combined inspection machine includes an upper star plate 3 and a lower star plate 4 that are coaxially and vertically spaced and assembled on the rotating shaft 1 and have the same structure. The notches include an upper notch 5 on the upper star plate 3 and a lower notch 6 on the lower star plate 4. The upper notch 5 and the lower notch 6 have the same structure and jointly form a receiving socket. The wine bottle 11 can be adaptively received in the receiving socket and move synchronously with the rotation of the star plate assembly.

[0024] The conveying chain plate 2 is arranged on one side outside the lower star plate 4 in a direction parallel to the tangent of the lower star plate 4. At the intersection of the conveying path and the rotation trajectory of the star plate assembly, the star plate assembly successively sleevs the bottle body of the wine bottle 11 on the conveying chain plate 2 through each receiving bayonet along with the rotation of the upper star plate 3 and the lower star plate 4, completing the reception of the wine bottle 11 conveyed by the conveying chain plate 2. The conveying chain plate 2 conveys from back to front. At the intersection of the rotation trajectory of the star plate assembly and the conveying path of the conveying chain plate 2, each receiving bayonet makes a circumferential displacement along the direction from back to front.

[0025] The steering wheel 10 contacts the outer wall of the lower end of the passing wine bottle 11, and realizes a certain degree of turning of the wine bottle through the contact, which is convenient for the detection camera to photograph multiple parts of the bottle body.

[0026] A light source controller, a display and a control system are provided. The light source controller, the display, the detection light source and the detection camera are electrically connected and controlled by the control system respectively. The control system controls the on / off of the detection light source through the light source controller, receives the information collected by the detection camera and displays it in real time through the display. The information displayed on the display can be used as the basis for judging the crack of the bottle body.

[0027] The detection principle of this embodiment is that the detection light source and the imaging end of the detection camera respectively face the part to be detected of the passing wine bottle 11, and are located at different positions. Using the principle that light generates specular reflection through crack defects, the detection camera receives the reflected light from the bottle body, and infers the presence or absence of crack defects by judging the intensity of the received light, and the detection is more accurate.

[0028] Taking the path of a single wine bottle as an example, the working process of this embodiment is introduced as follows:

[0029] When the wine bottle conveyed by the conveying chain plate reaches the intersection of the rotation trajectory of the star plate assembly of the combined inspection machine, along with the rotation of the star plate assembly, the star plate assembly successively takes the wine bottle on the conveying chain plate away from the conveying chain plate through each receiving bayonet, makes a circumferential displacement synchronously with the star plate assembly, reaches the detection station, and under the illumination of the detection light source, the detection camera collects information, which can be used as the basis for detecting the crack of the wine bottle.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the claims and their equivalents.
