Description

Technical Field

[0001] This utility model discloses a rotation detection device, belonging to the technical field of capsule detection devices, specifically relating to a 360-degree rotation detection device. Background Technology

[0002] Capsule inspection machines are key quality control equipment in pharmaceutical production. They are primarily used to automatically detect capsule filler weight variations, metal foreign objects, and appearance defects. Through real-time weighing, metal detection, and laser scanning technologies, they accurately reject defective products and provide data feedback to optimize production processes. Their functions encompass weight control, safety screening, size inspection, and electronic traceability, significantly improving product pass rates and reducing quality risks. They also support remote monitoring for intelligent production management.

[0003] In existing technologies, capsule testing machines need to perform 360-degree testing during operation. However, traditional testing devices require horizontal movement followed by rotational angle adjustment, making it impossible to perform both horizontal and rotational work simultaneously. This necessitates multiple operations to achieve 360-degree testing, resulting in low work efficiency. Utility Model Content

[0004] Purpose of the utility model: To provide a 360-degree rotating detection device to solve the problems mentioned above.

[0005] Technical solution: A 360-degree rotating detection device, comprising: a turntable assembly, a bracket, a drive wheel, a driven wheel, a detection camera, and a backlight;

[0006] The turntable assembly includes: a turntable plate, a turntable, a lower pressure plate, an upper pressure plate, and a spindle;

[0007] The bracket is disposed below the turntable assembly, and there is a gap between the bracket and the turntable. The driven wheel is disposed below the turntable, the upper surface of the driven wheel is flush with the upper surface of the bracket, and the driven wheel is connected to the driving wheel so that the driving wheel drives the driven wheel to rotate clockwise.

[0008] The backlight is located below the driven wheel, and the detection camera is vertically located above the turntable plate.

[0009] In a further embodiment, the turntable plate is welded to the turntable, and the lower pressure plate and the upper pressure plate are located below and above the turntable plate, respectively. The turntable plate, the lower pressure plate, and the upper pressure plate are combined and fixedly connected to the spindle.

[0010] In a further embodiment, the turntable plate, the lower pressure plate, and the upper pressure plate are provided with concentric circular holes of the same size at their centers. The turntable plate, the lower pressure plate, and the upper pressure plate are positioned as a whole through the circular holes and connected to the main shaft through the circular holes.

[0011] In a further embodiment, the gap between the frame and the turntable is adjusted according to the size of the capsule.

[0012] In a further embodiment, at least two detection cameras are provided.

[0013] Beneficial effects: After the capsule is successfully flattened in the turntable, it is carried by the turntable to move counterclockwise. When it passes the inspection station and enters the driven wheel surface from the bracket, due to the speed difference and rotation angle difference between the movement of the turntable and the driven wheel, the capsule rotates counterclockwise while following the revolution of the turntable. At the same time, the inspection system begins to inspect the entire capsule. For transparent capsules, it can also inspect both ends. Thus, this invention can perform horizontal and rotational work at the same time. By controlling the speed difference between the large and small turntables, the capsule can rotate 60 degrees for every unit distance it moves, and rotate 360 ​​degrees after moving 6 units, thereby greatly improving work efficiency.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] A 360-degree rotating detection device, such as Figure 1 and Figure 2 As shown, it includes: a turntable assembly, a bracket 1, a drive wheel 2, a driven wheel 3, a detection camera 4, and a backlight 5.

[0023] Example 1:

[0024] The turntable plate 6 is welded together with the turntable 7, and is fixed on the main shaft 10 by the lower pressure plate 8, the turntable plate 6, and the upper pressure plate 9. It is positioned as a whole by the central round hole. The bracket 1 is set below the turntable assembly and has a certain gap with the turntable 7. The gap size can be adjusted according to different capsule specifications. In the inspection station area, a driven wheel 3 is set below the turntable 7. The upper surface of the driven wheel 3 is flush with the upper surface of the bracket 1, and the driven wheel 3 is driven by the driving wheel 2 to move clockwise. When the capsule is successfully flattened in the turntable 7, it is carried by the turntable 7 to move counterclockwise. When it enters the plate surface of the driven wheel 3 from the bracket 1 at the inspection station, due to the speed difference and angle difference between the movement of the turntable 7 and the movement of the driven wheel 3, the capsule rotates counterclockwise while following the revolution of the turntable 7. At the same time, the inspection system begins to inspect the whole body of the capsule, and it can also inspect both ends of the transparent capsule.

[0025] Example 2:

[0026] like Figure 3 and Figure 4As shown, 2-3 industrial cameras are used above turntable 7 to capture images of the capsules. Each camera captures images of 3 capsules, and the combined field of view of the two cameras covers 6 capsules. The distance between two adjacent holes is called a unit distance. Each time turntable 7 moves by one unit distance, the camera captures an image. In this way, a capsule is captured in a total of 6 images after passing through the field of view of 2 cameras. Due to the special hardware design, the capsule can rotate while moving horizontally. By controlling the speed difference between the large and small turntables 7, the capsule can rotate 60 degrees for every unit distance it moves. After moving 6 unit distances, the capsule has rotated 360 degrees. In this way, the interior of the capsule can be captured with 360 degrees of the exterior.

[0027] The basic process of visual inspection algorithms can be divided into three parts: 7-axis localization, target localization, and target detection. 7-axis localization refers to accurately identifying the boundaries of the three holes in the image. Then, the capsule's outline is further precisely located within the hole area. The next step is to find the incisions of the capsule's cap and body, thus dividing the entire capsule into three regions: cap, overlapping area, and body. Based on the completed localization, the capsule's size and various defects can be detected.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
