Description

Technical Field

[0001] This utility model relates to the technical field of foreign object photography devices for the bottom of plastic bottles, and specifically to foreign object photography devices for the bottom of plastic bottles. Background Technology

[0002] The plastic bottle bottom foreign object photographing device is an automated device used to detect whether there are foreign objects at the bottom of plastic bottles. When it is working, the plastic bottle is transported to the detection station by a conveyor mechanism to ensure that the bottom is facing the image acquisition area; then, a high-definition camera takes a picture of the bottom of the bottle, thereby photographing the foreign objects inside the plastic bottle, improving product safety and detection efficiency.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Common plastic bottle bottom foreign object photography devices cannot adjust the position of the light source plane. When facing plastic bottles of different specifications (such as bottom thickness, curvature, and material), the fixed light source plane can easily cause some bottle bottoms to be too bright, resulting in reflection, or too dim, causing foreign objects to be hidden in shadows, making it difficult to clearly show tiny impurities. Utility Model Content

[0005] The purpose of this invention is to provide a device for photographing foreign objects at the bottom of plastic bottles, 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: a foreign object photographing device for the bottom of a plastic bottle, comprising a first mounting plate, a second mounting plate and a plastic bottle body, wherein a reinforcing rib is fixedly connected to the top center of the first mounting plate, a first fixing plate is fixedly connected to one side of the first mounting plate and the reinforcing rib, and a first adjusting component is provided on one side of the first fixing plate.

[0007] A second fixing plate is fixedly connected to the top of the second mounting plate, and a second adjustment component is provided on one side of the second fixing plate.

[0008] The first adjustment assembly includes a first connecting plate fixedly connected to the upper and lower parts of one side of a first fixed plate. A first outer shell is fixedly connected between the first connecting plates. A first threaded rod is provided on the inner side of the first outer shell. The bottom of the first threaded rod is connected to the output shaft of a first servo motor. A first threaded collar is threadedly connected to the outer side of the first threaded collar. A first connecting block is fixedly connected to the outer side of the first threaded collar. A support plate is fixedly connected to one side of the first connecting block. Sliding grooves are provided at both ends of one side of the support plate. A mounting base is slidably connected to the inner side of the sliding groove by bolts and nuts. A linear light source is installed on the top of the mounting base.

[0009] The second adjustment assembly includes a second connecting plate fixedly connected to the upper and lower parts of one side of the second fixed plate. A second housing is fixedly connected between the second connecting plates. A second threaded rod is provided on the inner side of the second housing. The bottom of the second threaded rod is connected to the output shaft of the second servo motor. A second threaded collar is threadedly connected to the outer side of the second threaded rod. A second connecting block is fixedly connected to the outer side of the second threaded collar. A mounting bracket is fixedly connected to one side of the second connecting block. A line scan camera is mounted on one side of the mounting bracket.

[0010] The beneficial effects of this utility model are as follows: the mounting base can slide inside the sliding groove, which can drive the linear light source to change its position and angle, thereby adjusting the incident angle of the light source. Furthermore, the first adjustment component can adjust the position of the light source on the intersecting plane, which can accurately adapt to plastic bottles of different specifications (such as height, bottom curvature, and thickness), avoid the light being blocked by the bottle body to form shadows, and also reduce reflection interference, ensuring that foreign objects are in the best light illumination area. At the same time, the object distance can be adjusted, thereby enabling an effective focusing process and making the image clearer.

[0011] To ensure effective installation:

[0012] Further configuration: The top four sides of both the first mounting plate and the second mounting plate are provided with first mounting grooves.

[0013] By adopting the above technical solution, the fixing bolts can be passed through the first mounting groove, and the first mounting plate and the second mounting plate can be installed in the corresponding area, which facilitates the subsequent photography process.

[0014] To enable adjustment of the incident angle of a line light source:

[0015] A further configuration is provided: a second mounting groove is provided on both the inner wall of the sliding groove and one side of the mounting base.

[0016] By adopting the above technical solution, the mounting base can slide inside the sliding groove, thereby causing the line light source to change its position and angle, thus allowing the incident angle of the light source to be adjusted.

[0017] To achieve adjustment of the position of the light source intersecting the plane:

[0018] The configuration is further defined as follows: the first servo motor and the first threaded rod form a rotating structure, and a first slot with the same external dimensions as the first connecting block is provided on the outer side of the first housing. The first threaded rod and the first threaded collar form a linkage structure through the cooperation of the first connecting block and the first slot.

[0019] By adopting the above technical solution, the first servo motor can drive the first threaded rod to rotate, thereby causing the threaded collar to move vertically under the limiting action of the first connecting block and the first slot, which in turn drives the line light source to adjust its height. This adjusts the position of the light source on the plane, preventing the light from being blocked by the bottle and forming a shadow, while also reducing reflection interference and ensuring that the foreign object is in the best light irradiation area.

[0020] To achieve object distance adjustment:

[0021] Further configuration: the second servo motor and the second threaded rod form a rotating structure, and a second slot with the same external dimensions as the second connecting block is provided on the outer side of the second housing. The second threaded rod and the second threaded collar form a linkage structure through the cooperation of the second connecting block and the second slot.

[0022] By adopting the above technical solution, the second servo motor can drive the second threaded rod to rotate, thereby causing the threaded collar to move vertically under the limiting action of the second connecting block and the second slot. This allows for adjustment of the distance between the line scan camera and the plastic bottle body, enabling effective focusing and resulting in a clearer image.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0039] The foreign object detection device at the bottom of the plastic bottle works as follows:

[0040] First, pass the fixing bolts through the first mounting slots of the first mounting plate 1 and the second mounting plate 2 respectively, thereby installing the first mounting plate 1 and the second mounting plate 2 in the corresponding areas. Next, slide the mounting base 609 inside the sliding groove 608 to adjust the incident angle of the linear light source 6010. When the adjustment is in a suitable position, pass the bolt through the second mounting groove, and then thread the nut onto the outside of the bolt to complete the installation process of the mounting base 609. When it is necessary to adjust the position of the light source intersecting the plane, the first servo motor 604 (model: 90ST-X02430-EX) can be turned on. The output shaft of the first servo motor 604 will drive the first threaded rod 603 to rotate, thereby causing the first threaded collar 605 to move vertically under the limiting action of the first connecting block 606 and the first groove, so that the first connecting block 606 slides inside the first groove, thereby driving the linear light source 6010 through the support plate 607. 10. Adjust the height to facilitate the adjustment of the light source's position relative to the plane according to the specifications of the plastic bottle body 3, avoiding shadows or reflections. When the object distance needs adjustment, the second servo motor 804 (model: 90ST-X02430-EX) can be turned on. The output shaft of the second servo motor 804 will drive the second threaded rod 803 to rotate, thereby causing the second threaded collar 805 to move vertically under the limiting action of the second connecting block 806 and the second slot. This allows the second connecting block 806 to slide inside the second slot, thereby driving the line scan camera 808 to adjust its height through the mounting bracket 807, thus adjusting the distance between the line scan camera 808 and the plastic bottle body 3, ensuring effective focusing and making the image clearer. When the plastic bottle body 3 is transported above the line scan camera 808, the line scan camera 808 can be activated to take pictures of foreign objects at the bottom of the plastic bottle body 3.
