Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] like Figures 1 to 3As shown, in this embodiment, the detection device for the can assembly includes: a first conveying structure 10, a second conveying structure 20, a receiving structure 30, a lid detection element 40, and a lid-fastening structure 50. The first conveying structure 10 is used to transport the can. The second conveying structure 20 is disposed above the first conveying structure 10 and is used to transport the lid. The receiving structure 30 is disposed downstream of the second conveying structure 20 and is capable of receiving the lid. The lid detection element 40 is disposed above the receiving structure 30 and is capable of detecting the shape of the lid. The lid-fastening structure 50 is disposed on the side of the lid detection element 40. The lid-fastening structure 50 includes a first driving element 51 and a gripping part 52 disposed at the driving end of the first driving element 51. The gripping part 52 is capable of gripping the lid, and the first driving element 51 can drive the gripping part 52 to move. The first conveying structure 10 can transport the can to the position corresponding to the lid-fastening structure 50.

[0028] Using the technical solution of this embodiment, the first conveying structure 10 is used to transport the can, and the second conveying structure 20 is used to transport the lid. The second conveying structure 20 is located above the first conveying structure 10. The receiving structure 30 is located downstream of the second conveying structure 20 and can receive the lid. The lid detection component 40 is located above the receiving structure 30 and can detect the shape of the lid. The lid-fastening structure 50 is located on the side of the lid detection component 40. The lid-fastening structure 50 includes a first driving component 51 and a gripping part 52, which can grip the lid. With the above configuration, the lid is conveyed to the receiving structure 30 via the second conveying structure 20. The lid detection component 40 can detect the lid and identify whether it is damaged. The lid-fastening structure 50 can grip the lid. When the can corresponds to the lid-fastening structure 50, the lid-fastening structure 50 can fasten the lid onto the can. This configuration allows for the lid to be detected first, thus identifying whether it is damaged. When subsequent detection is performed, it can be determined whether the damage is to the can or the lid. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where it is impossible to determine whether the damage is to the cover or the tank, which in turn affects production efficiency.

[0029] Through the coordinated action of the first conveying structure 10 and the second conveying structure 20, precise alignment of the tank and the cover is achieved, facilitating subsequent inspection and assembly operations. Furthermore, this design improves inspection efficiency and accuracy, reducing inspection errors caused by misalignment.

[0030] The process involves the can and the lid being transported by the first conveying structure 10 and the second conveying structure 20, respectively. After the lid inspection component 40 performs shape inspection, the gripping part 52 of the lid-fastening structure 50 accurately grips the lid and places it at the opening of the can, completing the initial assembly.

[0031] like Figures 1 to 3As shown, in this embodiment, the receiving structure 30 includes a receiving member 31 and a second driving member 32. The receiving member 31 has a storage position corresponding to the second conveying structure 20 and a closing position located below the closing structure 50. The second driving member 32 can drive the receiving member 31 to switch between the storage position and the closing position. The above-described configuration, through the control of the second driving member 32, enables the receiving member 31 to move between different positions to adapt to the detection of the cover and subsequent closing operations, ensuring the stability and accuracy of the cover during the detection and installation process.

[0032] like Figures 1 to 3 As shown, in this embodiment, the receiving member 31 is provided with a receiving recess 311, and the receiving member 31 is lower than the end of the second conveying structure 20 adjacent to the receiving structure 30. The aforementioned receiving recess 311 provides a stable support platform for the cover, and by reducing the height of the receiving member 31, it ensures that the cover can smoothly transition from the second conveying structure 20 to the receiving structure 30, avoiding tilting or falling of the cover due to height difference. This effectively improves the stability of the cover during the detection process, reduces the cover position displacement caused by height difference, and ensures the accuracy of the detection.

[0033] like Figures 1 to 3 As shown, in this embodiment, the receiving recess 311 has an opening 312 on the side facing the second conveying structure 20. The opening 312 allows the cover to smoothly enter the receiving recess 311 from the second conveying structure 20, and facilitates its removal by the gripping part 52 of the cover-fastening structure 50 after inspection. This effectively improves the smoothness and automation of the cover inspection process, reduces obstacles during transport, and ensures successful inspection and installation of the cover.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the height of the second conveying structure 20 gradually decreases in the direction from upstream to downstream of the first conveying structure 10. This gradual change in height of the second conveying structure 20 allows the cover to smoothly transition to the receiving structure 30, preventing instability or collisions caused by sudden height changes.

[0035] Furthermore, this change in height allows the cover to slide using its own weight.

[0036] like Figure 1 and Figure 4As shown, in this embodiment, the detection device for the tank assembly further includes a tank detection structure 60, which is disposed on the first conveying structure 10 and located downstream of the capping structure 50 in the conveying direction of the first conveying structure 10. After the cap and the tank are assembled, the overall sealing performance of the tank assembly is detected by the tank detection structure 60 to ensure a tight connection between the tank and the cap.

[0037] like Figure 1 and Figure 4 As shown, in this embodiment, the tank inspection structure 60 includes a housing 61 with an inlet and an outlet. A first lifting door 62 is provided at the inlet, and a second lifting door 63 is provided at the outlet. The enclosed environment of the housing 61, along with the control of the first and second lifting doors 62 and 63, provides a stable testing environment for the sealing performance testing of the tank assembly. This effectively improves the accuracy of the sealing performance testing and reduces the influence of external factors on the test results.

[0038] like Figure 1 and Figure 4 As shown, in this embodiment, an observation window 611 is provided on the side wall of the housing 61, and a pressure display 612 is provided inside the housing 61. The observation window 611 allows the operator to directly observe the testing status of the tank assembly inside the housing 61, while the pressure display 612 is used to monitor pressure changes inside the housing 61 and determine the sealing performance of the tank assembly.

[0039] Specifically, in this embodiment, the tank detection structure 60 is a vacuum chamber. The lifting rod can be moved by the extension end of the cylinder, thereby controlling the opening or closing of the first lifting door 62 and the second lifting door 63. During the opening of the first lifting door 62 and the second lifting door 63, the color mark sensor can detect whether the locking piece on the cover has fallen off. When the first lifting door 62 and the second lifting door 63 are in the closed state, the vacuum pump is started to make the interior of the vacuum chamber reach a certain vacuum degree. During this process, the state of the tank and the cover is observed through the observation window 611. If the cover has no obvious deformation, bulging or air leakage, and there is no air leakage in the tank that causes a significant change in the vacuum degree, it indicates that the cover has good sealing performance. In a vacuum environment, it can also be judged whether there is a slight leak by observing whether bubbles are generated on the surface of the tank. If bubbles appear, it indicates that there is a sealing problem.

[0040] like Figure 1 and Figure 5As shown, in this embodiment, the detection device for the can assembly further includes a can clamping member 70 disposed on the first conveying structure 10. The can clamping member 70 includes a first clamping part 71 and a second clamping part 72, which are disposed opposite to each other, and a clamping space for fixing the can is provided between the first clamping part 71 and the second clamping part 72. This above-mentioned arrangement provides stable support and fixation for the can, ensuring the stability of the can's position during the detection and assembly process. This improves the stability of the can during the detection and assembly process and reduces detection errors and assembly failures caused by unstable can position.

[0041] like Figure 1 and Figure 5 As shown, in this embodiment, the first clamping part 71 includes a first base 711, a first arcuate part 712, a first guide structure 713, and a first elastic member 714. The first guide structure 713 and the first elastic member 714 are disposed between the first base 711 and the first arcuate part 712. The first base 711 is fixedly disposed, and the first elastic member 714 can drive the first arcuate part 712 to move toward the second clamping part 72. And / or, the second clamping part 72 includes a second base 721, a second arcuate part 722, a second guide structure 723, and a second elastic member 724. The second guide structure 723 and the second elastic member 724 are disposed between the second base 721 and the second arcuate part 722. The second base 721 is fixedly disposed, and the second elastic member 724 can drive the second arcuate part 722 to move toward the first clamping part 71. The elastic clamping mechanism of the first clamping part 71 and the second clamping part 72 provides adaptive clamping force for tanks of different specifications, ensuring the tanks are firmly fixed during the inspection and assembly process, thereby improving the flexibility and applicability of tank clamping and reducing clamping failures caused by differences in tank specifications.

[0042] The working process of the detection device for the tank assembly in this embodiment is as follows:

[0043] First, the can is placed inside the can clamping member 70, and the lid is placed on the second conveying structure 20. The lid naturally slides into the receiving recess 311. At this time, the telescopic end of the telescopic member extends downward, driving the lid detection member 40 to move downward, so that the probe of the lid detection member 40 contacts the surface of the lid, which can collect coordinate data of multiple measurement points. Then, computer software is used for data processing and analysis. It can not only measure conventional parameters such as the diameter, height, and thread size of the lid, but also accurately measure the complex shape and contour of the lid to obtain more comprehensive dimensional information. After the test is completed, if there are no dimensional problems with the lid, it will extend forward through the telescopic end of the second driving member 32, driving the receiving member 31 and the lid in the receiving recess 311 to move forward and move to below the lid-fastening structure 50. The first driving member 51 then drives the lid to move forward. The gripping part 52 grips and tightens the lid. The inner side of the lid has spiral patterns, and the outer side of the can opening also has corresponding spiral patterns. By rotating the lid, the threads of both engage, achieving a sealed connection. After connection, the extension end of the cylinder drives the lifting rod to move, thereby controlling the opening and closing of the first lifting door 62 and the second lifting door 63. During the opening of the first lifting door 62 and the second lifting door 63, the color mark sensor can detect whether the locking plate of the lid has fallen off. When the first lifting door 62 and the second lifting door 63 are closed, the vacuum pump is activated to achieve a certain vacuum level inside the vacuum chamber. During this process, the state of the can and lid is observed through the observation window 611. If the lid shows no obvious deformation, bulging, or leakage, and there is no significant change in vacuum level due to air leakage inside the can, it indicates that the lid has good sealing performance. Furthermore, in a vacuum environment, the presence of bubbles on the surface of the can can be used to determine if there is any minor leakage. If bubbles appear, it indicates a sealing problem.

[0044] The tank assembly inspection device of this embodiment achieves efficient matching inspection of the tank and lid through an integrated inspection process. The synergistic effect of the first conveying structure 10 and the second conveying structure 20 ensures precise alignment of the tank and lid, improving inspection efficiency and accuracy. The design of the receiving structure 30 and the lid inspection component 40 makes the lid positioning more accurate during the inspection process, ensuring the reliability of the inspection results. The introduction of the lid-fastening structure 50 not only simplifies the lid gripping and placement steps but also enhances the automation of the inspection process, reduces manual intervention, and lowers the operational difficulty. The tank inspection structure 60, especially the pressure display 612 and observation window 611 inside the housing 61, provides a direct basis for the inspection of the tank's sealing performance, ensuring the overall quality of the tank assembly. The use of the tank clamping component 70 effectively prevents displacement of the tank during the inspection process, improving the stability and safety of the inspection.
