Description

Technical Field

[0001] This utility model relates to the field of bottle cap quality inspection technology, specifically to an optical inspection mechanism for detecting defective bottle caps. Background Technology

[0002] The optical inspection device used for defective bottle caps is mainly an automatic optical inspection system. This system uses a high-resolution industrial camera combined with a ring light source and a backlight to analyze various problems on the bottle cap surface in real time, such as scratches, stains, deformation, and even color deviation. It mainly detects problems such as burrs, buckle tears, pull ring problems, or bottle cap gaps.

[0003] Conventional optical inspection mechanisms are directly installed and fixed on one side of the material conveying device. The installation structure is relatively fixed, making it difficult to make appropriate adjustments to the optical inspection device itself. At the same time, its open structure is also prone to structural damage, which affects the inspection and service life.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an optical inspection mechanism for detecting bottle cap defects. Utility Model Content

[0005] The purpose of this invention is to provide an optical inspection mechanism for detecting defective bottle caps, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical inspection mechanism for detecting defective bottle caps, comprising an inspection component and a triangular plate. The top of the inspection component is connected to the triangular plate, and a rotating frame is connected to the side of the triangular plate away from the inspection component. A swing frame is installed at the end of the rotating frame away from the triangular plate, and a fixed frame is connected to the side of the swing frame away from the rotating frame. The inspection component includes a protective shell, an optical industrial camera, a fixed plate, and a data connector. The optical industrial camera is installed inside the protective shell, and a fixed plate is connected to the side of the protective shell near the triangular plate. A data connector is installed on one side of the protective shell.

[0007] Furthermore, the data connector is electrically connected to the optical industrial camera inside the protective housing, and the protective housing and the fixing plate are integrally structured.

[0008] Furthermore, the triangular plate has a groove structure on the side surface near the detection component that matches the side surface of the fixed plate, and holes for bolt installation are provided at the four opposite corners of the triangular plate where it connects with the fixed plate.

[0009] Furthermore, the rotating frame includes a support arm, a damping shaft, and a docking plate. The damping shaft is installed at the end of the support arm away from the triangular plate, and the output end of the damping shaft is connected to the docking plate.

[0010] Furthermore, the support arm and the triangular plate are welded together, and the damping shaft is installed inside the support arm at the end away from the triangular plate, and the damping shaft and the mating plate are fixedly connected to each other.

[0011] Furthermore, the swing frame includes a damping hinge, a stabilizing pile, and a docking pile. The end of the damping hinge closest to the fixed frame is connected to the stabilizing pile, and the end of the damping hinge furthest from the stabilizing pile is connected to the docking pile.

[0012] Furthermore, the stabilizing pile and one end of the damping hinge are integrally structured, and the stabilizing pile and the fixing frame are welded together. Moreover, the surface of the fixing frame is provided with holes of various specifications for bolts to pass through and be adjusted.

[0013] Furthermore, the surface of the docking pile near the docking plate is provided with a groove structure that matches the surface structure of the docking plate, and the four opposite corners of the docking point of the docking plates are provided with holes for installing bolts.

[0014] This invention provides an optical inspection mechanism for detecting defective bottle caps, which has the following advantages:

[0015] 1. This utility model, by installing an optical industrial camera inside a protective shell connected to a fixing plate, allows the entire detection assembly to be screwed into the four diagonal holes of the fixing plate using four sets of bolts. Simultaneously, the fixing plate is aligned with a triangular plate, and the four sets of bolts are screwed into the four diagonal holes at the alignment point of the triangular plate. This allows for quick connection of the detection assembly and the triangular plate. A data connector on one side of the protective shell is electrically connected to the optical industrial camera. Using this structure, on the one hand, it provides excellent structural protection for the optical industrial camera, preventing unnecessary impact from external factors during operation; on the other hand, the structure allows for flexible assembly and disassembly of the detection assembly and the triangular plate, facilitating structural maintenance of the optical industrial camera.

[0016] 2. This utility model, by setting up a rotating frame and a swing frame, wherein the damping shaft at one end of the support arm can provide axial rotation adjustment in the vertical direction, and the damping shaft can provide vertical swing adjustment within a certain angle range in the vertical direction, the use of the above structure can ensure that the detection component connected to it through the triangular plate has good structural mobility, so that the user can adjust the structural orientation to ensure the detection component can detect materials. In addition, due to the setting of the fixed frame, the different specifications of the hole structure opened on its surface can be used within a certain range, with the use of bolts or fixed structures, so that the entire device can be flexibly installed on the side of the material conveying track to ensure the stable operation of the detection component. Furthermore, the rotating frame and the swing frame are connected by the docking plate and docking pile with bolts, thereby achieving structural disassembly to facilitate structural maintenance.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, an optical inspection mechanism for detecting defective bottle caps includes a detection component 1 and a triangular plate 2. The triangular plate 2 is connected to the top of the detection component 1, and a rotating frame 3 is connected to the side of the triangular plate 2 away from the detection component 1. A swing frame 4 is installed at the end of the rotating frame 3 away from the triangular plate 2, and a fixed frame 5 is connected to the side of the swing frame 4 away from the rotating frame 3. The detection component 1 includes a protective shell 101, an optical industrial camera 102, a fixed plate 103, and a data connector 104. The optical industrial camera 102 is installed inside the protective shell 101, and the fixed plate 103 is connected to the side of the protective shell 101 near the triangular plate 2. The data connector 104 is installed on one side of the protective shell 101. The data connector 104 connects to the optical sensor inside the protective shell 101. The industrial camera 102 is electrically connected, and the protective shell 101 and the fixing plate 103 are integrally structured. The side surface of the triangular plate 2 near the detection component 1 has a groove structure that matches the side surface of the fixing plate 103. The four diagonal corners of the triangular plate 2 and the fixing plate 103 are provided with holes for bolt installation. By installing the optical industrial camera 102 inside the protective shell 101 connected to the fixing plate 103, the entire detection component 1 can be screwed into the holes at the four diagonal corners of the fixing plate 103 using four sets of bolts. At the same time, the fixing plate 103 and the triangular plate 2 are connected, and the four sets of bolts are screwed into the holes at the four diagonal corners of the connection of the triangular plate 2. In this way, the detection component 1 and the triangular plate 2 can be quickly connected.

[0024] like Figures 1 to 4As shown, the rotating frame 3 includes a support arm 301, a damping shaft 302, and a docking plate 303. The damping shaft 302 is installed at the end of the support arm 301 away from the triangular plate 2, and the output end of the damping shaft 302 is connected to the docking plate 303. The support arm 301 and the triangular plate 2 are welded together, and the damping shaft 302 is installed inside the end of the support arm 301 away from the triangular plate 2. The damping shaft 302 and the docking plate 303 are fixedly connected to each other. The swing frame 4 includes a damping hinge 401, a stabilizing pile 402, and a docking pile 403. The stabilizing pile 402 is connected at the end of the damping hinge 401 near the fixed frame 5, and the docking pile 403 is connected at the end of the damping hinge 401 away from the stabilizing pile 402. The stabilizing pile 402 and the end of the damping hinge 401 are connected to each other. The structure is designed with a welded connection between the stabilizing pile 402 and the fixing frame 5. The surface of the fixing frame 5 has holes of various sizes for bolts to pass through and adjust. The side of the docking pile 403 near the docking plate 303 has a groove structure that matches the surface structure of the docking plate 303. The four diagonal corners of the docking point of the docking plates 303 have holes for installing bolts. The damping shaft 302 at one end of the support arm 301 can provide axial rotation adjustment in the vertical direction, while the damping shaft 302 can provide vertical swing adjustment within a certain angle range in the vertical direction. In addition, the rotating frame 3 and the swing frame 4 are connected by the docking plate 303 and the docking pile 403 with bolts, thereby realizing the structural disassembly.

[0025] In summary, as Figures 1 to 4 As shown, the optical inspection mechanism for detecting defective bottle caps is used by first fitting the entire device with appropriate bolts using a fixing frame 5 with holes of different sizes on its surface, according to the inspection requirements. Depending on the condition of the mounting structure and the installation position, the bolts are passed through the holes on the surface of the fixing frame 5, and then the bolts are screwed into the holes corresponding to the structure pre-drilled on the mounting structure to complete the structure fixing.

[0026] Then, based on the transmission position of the bottle cap on the conveying device, the damping shaft 302 installed at one end of the support arm 301 and the structural mobility adjustment of the damping hinge 401 are used to realize circumferential rotation and swing adjustment, thereby adjusting the detection component 1 connected to the triangular plate 2 at one end of the rotating frame 3 to a suitable orientation to ensure that the optical industrial camera 102 installed inside the protective shell 101 can accurately perform detection. After that, it is only necessary to use the data connector 104 on one side of the protective shell 101 to connect the optical industrial camera 102 to the control system to ensure data transmission and retrieval and identification of whether the bottle cap is good or bad.

[0027] In addition, multiple sets of detection components 1 can be installed on the track or one side of the conveying device for conveying bottle caps as needed, which can realize the function of multiple re-inspection, thereby minimizing the occurrence of missed inspections and improving the yield rate.
