Description

Technical Field

[0001] This utility model relates to the field of bottle material conveying technology, and in particular to a solvent bottle body inspection station. Background Technology

[0002] Bottle material handling refers to the automated handling and transmission of bottles (such as beverage bottles and medicine bottles) during production, packaging, or logistics. This technology is an important component of modern industry, especially in the food and beverage and pharmaceutical sectors, aiming to improve production efficiency, reduce labor costs, and ensure product quality.

[0003] To ensure product quality, cameras or other sensors are typically installed on conveyor lines to check for bottle defects, cleanliness, and proper filling. However, when checking for cleanliness or proper filling, detecting any residual liquid inside and on the surface of the bottle from only one direction can easily lead to overlooking undetected liquid due to the bottle's structural material (such as a concave bottom). Therefore, it is often necessary to flip the bottle, turning it horizontally or even upside down, to inspect the bottle and its contents. Current technology usually involves flipping the grippers or similar structures that hold the bottle. However, when the bottle is heavy or contains a lot of material, and horizontal flipping is required, gravity exerts a significant force on the grippers, preventing complete horizontal flipping. In cases where the bottle is flexible, the gripping structure may even deform relative to the bottle, affecting inspection results and production. Utility Model Content

[0004] This utility model discloses a solvent bottle body inspection station to solve the technical problem of difficulty in detecting the flipping of the bottle body in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution: This utility model proposes a solvent bottle body inspection station, which is applied to bottle body inspection. The inspection station includes: A bottle-holding mechanism, comprising a bottle-holding line and a fixing line mechanism, wherein the bottle-holding line is disposed on one side of the bottle body and engages with the bottle body for limiting, and the fixing line mechanism connects to the bottle-holding line and limits its position so that the bottle-holding line is tightly attached to one side of the bottle body; The testing mechanism includes a lighting module and a camera module. The camera module is located on one side of the bottle and faces the bottle. The lighting module is located on the same side and / or opposite side of the bottle relative to the camera module.

[0006] Furthermore, the axial direction of the bottle-supporting line is parallel to the transport direction of the bottle body through the detection station, and the bottle-supporting line is located on the lower side of the bottle body and is vertically matched with the bottle body for positioning.

[0007] Furthermore, the fixing mechanism includes a fixing mechanism that passes through the bottle-holding line, and the fixing mechanism limits the bottle-holding line in the axial direction of the bottle-holding line to fix the length of the bottle-holding line.

[0008] Furthermore, the bottle-holding mechanism also includes a tensioning mechanism, on which at least a portion of the bottle-holding line is wound, and the tensioning mechanism is configured to adjust the tension of the bottle-holding line.

[0009] Furthermore, the tensioning mechanism can move along the extension direction of the bottle-supporting line or in the vertical direction to change the sum of the distances between each group of tensioning mechanisms or fixing mechanisms and adjacent tensioning mechanisms or fixing mechanisms, thereby adjusting the tension of the bottle-supporting line.

[0010] Furthermore, one set of the fixing mechanism and one set of the tightening mechanism are provided. One of the fixing mechanism and the tightening mechanism is located at one end of the movement path of the bottle body at the detection station, and the other is located at the other end of the movement path of the bottle body. One end of the bottle-supporting line is connected to the fixing mechanism, and the other end of the bottle-supporting line passes through the tightening mechanism and is connected to the fixing mechanism.

[0011] Furthermore, at least two sets of the fixing mechanism are provided, with two sets respectively located at the far end and near end of the movement path of the bottle body at the detection station, and the remaining fixing mechanisms located in the middle of the movement path of the bottle body.

[0012] Furthermore, the bottle-holding line is connected end to end, and at least two sets of the tensioning mechanism are provided. At least one of the tensioning mechanisms can move along the extension direction of the bottle-holding line to change the distance between the two sets of tensioning mechanisms.

[0013] Furthermore, the testing station also includes a mounting frame for mounting the bottle-holding mechanism and the testing mechanism. The mounting frame is located on one side of the bottle transport mechanism, and the bottle passes through the mounting frame.

[0014] Furthermore, the camera module and the lighting module are respectively located on the upper and lower sides of the bottle body.

[0015] The technical solution adopted in this utility model can achieve the following beneficial effects: The bottle-supporting line provides unilateral limiting support for the bottle, preventing lateral shifting or tipping during inspection and avoiding interference with bottle transport, thus improving inspection stability. Furthermore, because the bottle-supporting line supports and limits the bottle, it minimizes obstruction of the bottle, preventing interference at the inspection station. This simplifies image processing by the camera module and increases inspection speed. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] In the various embodiments of this application, "proximal end" and "far end" refer to the position of each component relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "far end".

[0022] When checking whether bottles are clean or correctly filled, inspecting only one direction for any residual liquid inside and on the surface can easily lead to overlooking undetected liquid due to bottle structure materials (such as a concave bottom). Therefore, it is often necessary to flip the bottle, turning it horizontally or even upside down, to inspect the bottle and its contents. Current technology typically involves flipping the grippers or similar structures holding the bottle. However, when the bottle is heavy or contains a lot of material, and horizontal flipping is required, gravity exerts a significant force on the grippers, preventing complete horizontal flipping. In cases with softer bottles, the gripping structure may even deform relative to the bottle, affecting inspection results and production. Therefore, it is necessary to provide some degree of support and restraint to the bottle without affecting the inspection process.

[0023] The following is in conjunction with the appendix Figure 1 and Figure 2 The re-inspection system provided in this application will be described in detail through specific embodiments and application scenarios.

[0024] Please see Figure 1 and Figure 2 This application discloses a solvent bottle body inspection station, which is applied to bottle body inspection. The inspection station includes a bottle-supporting mechanism 300 and an inspection mechanism 200. For example, the solvent bottle body inspection station is used for horizontal flipping inspection of the bottle body. The bottle body transport mechanism flips the bottle body to a horizontal position, and then it passes through the solvent bottle body inspection station for inspection. During passage, the bottle-supporting mechanism 300 supports the flipped bottle body to prevent it from deforming under gravity or failing to flip properly, thus affecting the inspection. Then, the inspection mechanism 200 inspects the flipped bottle body.

[0025] This technical solution can prevent the bottle from shifting laterally or tipping over during the testing process, thus improving testing stability.

[0026] Reference Figure 1 and Figure 2In some embodiments, the bottle-supporting mechanism 300 includes a bottle-supporting line 310 and a line-fixing mechanism 320. The bottle-supporting line 310 is located on one side of the bottle body and engages with the bottle body for positioning. The line-fixing mechanism 320 connects to the bottle-supporting line 310 and limits its position, so that the bottle-supporting line 310 is tightly attached to one side of the bottle body. For example, the bottle-supporting line 310 is located below or to one side of the bottle body's transport trajectory. The line supports the bottle body, while the line-fixing structure ensures the position and tension of the line, guaranteeing that the line can effectively support the bottle body.

[0027] Using this technical solution, the bottle support line 310 fits tightly against the bottle body, forming a flexible contact. This effectively limits the movement without causing scratches or damage to the bottle body due to rigid contact. Furthermore, the line itself minimizes occlusion of the bottle body, facilitating image processing and thus improving detection speed and accuracy.

[0028] Reference Figure 1 and Figure 2 In some embodiments, the detection mechanism 200 includes an illumination module 210 and a camera module 220. The camera module 220 is disposed on one side of the bottle and faces the bottle body, while the illumination module 210 is disposed on the same side and / or opposite side of the bottle body relative to the camera module 220. For example, the camera module 220 can be configured as an industrial area scan camera or a line scan camera, and the illumination module 210 is an LED light source, which can be configured as a ring light, a strip light, or a backlight. When the illumination module 210 and the camera module 220 are located on the same side of the bottle body, a bright field or dark field illumination method is used to detect defects such as scratches, stains, and label abnormalities on the bottle surface. When the illumination module 210 and the camera module 220 are located on opposite sides of the bottle body, a transmissive backlight imaging structure is formed to detect internal or contour features such as bottle bottom cracks, internal foreign objects, uneven wall thickness, and liquid level height.

[0029] By employing this technical solution, the relative positions of the lighting module 210 and the camera module 220 can be flexibly configured to enable switching and combination of various imaging modes, adapting to the detection needs of different types of defects. Illumination on the same side helps to highlight surface textures and imperfections, enhancing the ability to identify appearance defects such as scratches, indentations, and unclear coding; while the opposite side arrangement forms a high-contrast transmission image, making the internal structure of the bottle clearly visible, significantly improving the detection rate of hidden defects.

[0030] Reference Figure 1 and Figure 2In some embodiments, the bottle-supporting line 310 extends parallel to the transport direction of the bottle body through the detection station. The bottle-supporting line 310 is located on the lower side of the bottle body and engages with the bottle body in a vertical direction. For example, the camera module 220 can be configured as an area scan camera. The illumination module 210 and the camera module 220 are respectively located on the upper and lower sides of the bottle body. The illumination module 210 illuminates the bottle body from above, and the camera module 220 is located below the bottle body to acquire image information transmitted through the bottle body.

[0031] This technical solution, by arranging the lighting module 210 and the camera module 220 on the upper and lower sides of the bottle respectively, forms a transmissive backlight imaging structure. This significantly improves image contrast, making defects such as cracks, inclusions, bubbles, and uneven wall thickness inside and at the bottom of the bottle appear as clear dark areas in the image, thereby improving the accuracy and detection rate of defect identification. Simultaneously, this layout avoids specular reflection interference caused by same-side lighting, making it particularly suitable for detecting bottles made of highly reflective materials. Furthermore, the upper and lower opposing structure does not occupy the lateral space of the conveyor line, which is beneficial for equipment miniaturization and modular integration.

[0032] Reference Figure 1 and Figure 2 In some embodiments, the securing mechanism 320 includes a clamping assembly for securing the bottle-carrying line 310, which passes through the securing mechanism 320. The securing mechanism 320 limits the axial movement of the bottle-carrying line 310 to fix its length. Exemplarily, the securing mechanism 320 may employ a bolt-on clamp or a quick-change clamp structure to reliably secure the end or middle section of the bottle-carrying line.

[0033] This technical solution uses a fixing mechanism 320 to axially limit the bottle-supporting line, ensuring it will not slip or loosen during use, maintaining stable tension, and thus providing continuous and effective restraint for the bottle. This structure is simple, reliable, easy to install and maintain, and suitable for automated production lines operating continuously for extended periods.

[0034] Reference Figure 1 and Figure 2 In some embodiments, the bottle-supporting mechanism 300 further includes a tensioning mechanism 330, around which at least a portion of the bottle-supporting line 310 is wound, and the tensioning mechanism 330 is configured to adjust the tension of the bottle-supporting line 310. For example, the tensioning mechanism 330 may be an adjusting assembly with guide wheels or support rollers, which can both tension the bottle-supporting line and prevent it from sagging due to its own weight.

[0035] By adopting this technical solution, the tensioning mechanism 330 not only achieves tension adjustment, but also provides lateral support, enhances the overall rigidity of the bottle-carrying line, avoids the phenomenon of sagging in the middle when laying long-distance lines, and ensures that the bottle body is evenly supported throughout the entire detection stroke, thereby improving the smoothness of conveying and the accuracy of detection.

[0036] Reference Figure 1 and Figure 2 In some embodiments, the tensioning mechanism 330 can move along the extension direction of the bottle-supporting line 310 or in the vertical direction, so as to change the sum of the distances between each group of tensioning mechanisms 330 or the fixing mechanism 320 and the adjacent tensioning mechanism 330 or the fixing mechanism 320, thereby adjusting the tension of the bottle-supporting line 310. For example, the tensioning mechanism 330 includes a guide wheel, a support arm, and a sliding adjustment assembly. The bottle-supporting line 310 passes through the guide wheel, and the sliding adjustment assembly is mounted on a mounting frame and can be adjusted in the horizontal or vertical direction, thereby driving the support arm and the guide wheel to move within the plane of the bottle-supporting line, realizing dynamic adjustment of the direction and tension of the bottle-supporting line.

[0037] By adopting this technical solution, the direction and tension of the bottle-supporting line 310 can be dynamically adjusted by regulating the position of the tensioning mechanism 330, adapting to the limiting requirements of different bottle types (such as changes in diameter and height) and enabling rapid changeover. This design can meet the application requirements of multi-variety, small-batch production scenarios.

[0038] Reference Figure 1 and Figure 2 In some embodiments, a set of fixing mechanism 320 and a set of tightening mechanism 330 are provided. One of the fixing mechanism 320 and the tightening mechanism 330 is located at one end of the movement path of the bottle body at the detection station, and the other is located at the other end. One end of the bottle-supporting line 310 is connected to the fixing mechanism 320, and the other end of the bottle-supporting line 310 is connected to the fixing mechanism 320 after passing through the tightening mechanism 330. For example, the fixing mechanism 320 is located at the bottle outlet end of the detection station to fix both ends of the bottle-supporting line 310, and the tightening mechanism 330 is located at the bottle inlet end to tension and fine-tune the bottle-supporting line through an adjustable structure.

[0039] This technical solution creates a mechanical structure with "one end fixed and one end tensioned," which is simple in structure, rationally laid out, and easy to install and debug. By setting a fixing mechanism 320 and a tensioning mechanism 330 at both ends of the movement path, effective pre-tensioning of the bottle-supporting line can be achieved, preventing it from loosening or shifting during use and ensuring continuous and stable support and positioning of the bottle. This arrangement provides clear force distribution and uniform tension transmission, reducing manufacturing costs and improving maintenance convenience.

[0040] Reference Figure 1 and Figure 2 In some embodiments, at least two sets of fixing mechanisms 320 are provided, with two sets respectively located at the far end and near end of the bottle body's movement path at the inspection station, and the remaining fixing mechanisms 320 located in the middle area of ​​the bottle body's movement path. For example, multiple sets of fixing mechanisms 320 are arranged at intervals along the bottle body's conveying direction to segmentally fix the long-stroke bottle-supporting line, preventing it from sagging, swaying, or resonating due to its own weight or external disturbances.

[0041] This technical solution significantly enhances the overall rigidity and structural stability of the bottle-supporting line 310 through multi-point fixing, making it particularly suitable for long-distance transport or multi-station continuous inspection scenarios. The far-end and near-end fixing mechanisms 320 constitute the main anchor points, while the additional fixing mechanism 320 in the middle provides segmented constraint, effectively suppressing sagging and lateral swaying in the middle of the bottle-supporting line 310, thus ensuring stable support for the bottle throughout the entire inspection area. This design improves the stability and consistency of system operation, preventing bottle posture deviation caused by deformation of the bottle-supporting line 310, which could affect visual inspection accuracy.

[0042] Reference Figure 1 and Figure 2 In some embodiments, the bottle-supporting line 310 is connected end-to-end to form a closed-loop structure. At least two sets of tensioning mechanisms 330 are provided, and at least one of the tensioning mechanisms 330 can move along the extension direction of the bottle-supporting line 310 to change the distance between the two sets of tensioning mechanisms 330. For example, the bottle-supporting line 310 forms a circular loop, wound between multiple guide wheels, where at least one guide wheel is connected to an adjustable tensioning mechanism. Adjusting its position allows for tension control and fine-tuning of the closed-loop circuit.

[0043] Using this technical solution, the closed-loop bottle support line 310 can achieve continuous cyclic support, making it particularly suitable for complex motion conditions such as bottle flipping, rotation, or reciprocating conveying. Multiple tensioning mechanisms 330 work together to ensure balanced tension in each section of the closed-loop system; the movable tensioning mechanism provides dynamic adjustment capability to adapt to the support position and contact pressure requirements of different bottle types.

[0044] Reference Figure 1 and Figure 2 In some embodiments, the inspection station further includes a mounting frame 100 for mounting the bottle-holding mechanism 300 and the inspection mechanism 200. The mounting frame 100 is located on one side of the bottle transport mechanism, and the bottle passes through the mounting frame 100. For example, the mounting frame 100 is a metal frame structure, integrated with mounting interfaces for mounting the bottle-holding line 310, the line-fixing mechanism 320, the line-tightening mechanism 330, the camera module 220, and the lighting module 210, and is fixed as a whole to the side frame of the conveyor line.

[0045] Using this technical solution, the mounting frame serves as an integrated support platform, highly integrating the bottle-carrying mechanism and the testing mechanism, facilitating overall assembly, positioning, debugging, and subsequent maintenance. The mounting frame is located on one side of the transport mechanism, not occupying the lateral space of the conveyor channel, which is beneficial for a compact production line layout.

[0046] In some embodiments, the camera module 220 and the lighting module 210 are respectively disposed on the upper and lower sides of the bottle body. For example, the lighting module 210 is disposed above the bottle body, providing a vertically downward uniform surface light source or a strip light source; the camera module 220 is an area array camera, disposed below the bottle body, used to acquire transmitted light images through the bottle body, and is particularly suitable for detecting critical defects such as bottle bottom cracks, internal foreign objects, uneven wall thickness, and liquid level height.

[0047] This technical solution employs a top-and-bottom arrangement to form a typical transmissive backlight imaging system, capable of obtaining high-contrast, high-definition images of the bottle's outline and internal structure. Under this light path, the bottle exhibits an imaging characteristic of "bright background + dark defects," making defects such as micro-cracks, inclusions, and bubbles clearly visible, significantly improving the accuracy and detection rate of defect identification. This layout is particularly suitable for solvent bottle inspection stations where the bottle is bottom-down, allowing for comprehensive capture of defect information in traditional blind spots.

[0048] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
