Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, and in particular to an image acquisition device for a medicine box stamp with a height adjustable structure. Background Technology

[0002] The medicine box stamp image acquisition device is specifically designed to clearly capture the stamped characters on the surface of medicine boxes. It achieves accurate acquisition of stamped information through a combination of multispectral imaging technology and a high-precision industrial camera. Typically equipped with a ring LED light source, it uses infrared light to excite the thermal imaging contour of the stamped material, while simultaneously employing polarized light to suppress specular reflection, ensuring a clear and blur-free image. Combined with a high-speed industrial camera and telecentric lens, perspective distortion is eliminated, and synchronous shooting is triggered by a photoelectric sensor, ensuring precise positioning of the medicine box in the center of the field of view. This provides high-quality raw image data for subsequent character recognition and traceability management.

[0003] Existing image acquisition devices for medicine box stamps have a fixed acquisition position, relying solely on adjusting the medicine box's posture to meet acquisition requirements. When dealing with medicine boxes of different sizes, the inability to flexibly adjust the acquisition camera position severely limits the acquisition process and makes it difficult to guarantee acquisition quality. Furthermore, during production and transportation, dust and impurities easily accumulate on the surface of medicine boxes, interfering with image acquisition and reducing quality. Adding cleaning steps to avoid this problem would consume extra time, lengthening the entire acquisition process and significantly reducing efficiency, failing to meet the demands of high-efficiency production. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, this utility model provides a medicine box stamp image acquisition device with a height adjustable structure, which can meet the stamp acquisition needs of medicine boxes of different sizes, and can remove dust and impurities from the surface of the medicine box to ensure that the surface of the medicine box is clean during acquisition, thus effectively improving the quality of stamp image acquisition.

[0005] The technical solution adopted by this utility model is: a medicine box stamp image acquisition device with a height adjustable structure, including a mounting frame, a vertical mounting frame fixedly mounted on the mounting frame, a lifting drive assembly mounted on the inner wall of the vertical mounting frame, an extension block mounted on the lifting drive assembly, an acquisition camera and the positioning frame fixedly mounted on the extension block, a cleaning roller mounted on the inner wall of one end of the positioning frame for cleaning the surface of the medicine box, a vertical rack fixedly mounted on the outer wall of the mounting frame, and one end of the cleaning roller connected to the vertical rack through a synchronous rolling connection assembly.

[0006] Preferably, in order to control the rotation of the vertical threaded rod so that the lifting slider can move up and down, thereby driving the extension block to move up and down, the lifting drive assembly includes a vertical threaded rod, which is rotatably mounted on the inner wall of the vertical mounting frame. The lifting slider is threaded onto the vertical threaded rod, and the extension block is fixed on the lifting slider.

[0007] Preferably, in order to control the servo motor to turn on, the vertical threaded rod can rotate on the inner wall of the vertical mounting frame through a rotary joint. The servo motor is fixedly installed on the inner wall of one end of the vertical mounting frame, one end of the vertical threaded rod is fixedly connected to the output shaft of the servo motor, and the other end of the vertical threaded rod is rotatably installed on the inner wall of the other end of the vertical mounting frame through a rotary joint.

[0008] Preferably, in order to limit the movement of the lifting slider, the lifting slider is slidably engaged with the inner wall of the vertical mounting frame.

[0009] Preferably, in order to control the up and down movement of the extension block so that the lateral positioning head and the connecting plate can drive the rolling gear to roll on the vertical rack, the synchronous rolling connection assembly includes a lateral positioning head, a drive shaft and a driven shaft. The lateral positioning head is fixed on the side wall of the extension block, and a connecting plate is fixedly installed at one end of the lateral positioning head. A rolling gear is installed at one end of the connecting plate, and the rolling gear meshes with the vertical rack.

[0010] Preferably, in order to enable the rolling gear to rotate on the connecting strip via the drive shaft, the rolling gear is rotatably connected to the connecting strip via the drive shaft.

[0011] Preferably, in order to enable the drive shaft to drive the driven shaft to rotate via the timing belt, the driven shaft is fixed to one end of the cleaning roller and is connected to the drive shaft via the timing belt.

[0012] Preferably, the cleaning roller is provided with bristles so that the surface of the medicine box can be cleaned by brushing.

[0013] The beneficial effects of this utility model are: the height of the acquisition camera can be adjusted by the lifting drive component, which can meet the needs of steel stamp acquisition of medicine boxes of different sizes; at the same time, when the extension strip is raised and lowered, the synchronous rolling connection component makes the cleaning roller rotate accordingly, and its surface brush can remove dust and impurities from the surface of the medicine box, ensuring that the surface of the medicine box is clean during acquisition, and effectively improving the quality of steel stamp image acquisition.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-4 As shown, this embodiment provides a medicine box stamp image acquisition device with a height-adjustable structure, including a mounting frame 1, a vertical mounting frame 2 fixedly mounted on the mounting frame 1, a lifting drive assembly 3 mounted on the inner wall of the vertical mounting frame 2, an extension block 4 mounted on the lifting drive assembly 3, the lifting drive assembly 3 including a vertical threaded rod 301, the vertical threaded rod 301 being rotatably mounted on the inner wall of the vertical mounting frame 2, a lifting slider 302 being threadedly sleeved on the vertical threaded rod 301, the extension block 4 being fixed on the lifting slider 302, a servo motor 303 being fixedly mounted on the inner wall of one end of the vertical mounting frame 2, one end of the vertical threaded rod 301 being fixedly connected to the output shaft of the servo motor 303, and the other end of the vertical threaded rod 301 being rotatably mounted on the inner wall of the other end of the vertical mounting frame 2 through a rotating joint 304, the lifting slider 302 being slidably engaged with the inner wall of the vertical mounting frame 2, in use, the servo motor 303 is started, its output shaft drives the vertical threaded rod 301 to rotate. Because the lifting slider 302 is threaded onto the vertical threaded rod 301 and slidably engaged with the inner wall of the vertical mounting frame 2, the rotation of the threaded rod will cause the lifting slider 302 to move up and down. Furthermore, since the extension block 4 is fixed to the lifting slider 302, it will move up and down, thereby adjusting the height of the camera 5 mounted on the extension block 4 to meet the needs of acquiring images of stamped medicine boxes of different sizes.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 4As shown, a camera 5 and a positioning frame 6 are fixedly installed on the extension block 4. A cleaning roller 7 is installed on the inner wall of one end of the positioning frame 6 for cleaning the surface of the medicine box. A vertical rack 8 is fixedly installed on the outer wall of the mounting frame 1. One end of the cleaning roller 7 is connected to the vertical rack 8 through a synchronous rolling connection component 9. The synchronous rolling connection assembly 9 includes a lateral positioning head 901, a drive shaft 902, and a driven shaft 903. The lateral positioning head 901 is fixed on the side wall of the extension block 4. A connecting plate 904 is fixedly installed at one end of the lateral positioning head 901. A rolling gear 905 is installed at one end of the connecting plate 904. The rolling gear 905 meshes with the vertical rack 8. The rolling gear 905 is rotatably connected to the connecting plate 904 through the drive shaft 902. The driven shaft 903 is fixed at one end of the cleaning roller 7 and is connected to the drive shaft 902 through a synchronous belt 906. The surface of the cleaning roller 7 is provided with bristles. In use, the extension block 4 moves with the lifting structure, driving the lateral positioning head 901 and the connecting plate 904 to rise and fall synchronously. The rolling gear 905 at the end of the connecting strip 904 meshes with the vertical rack 8 fixed to the mounting frame 1. During movement, it rotates automatically, and via the drive shaft 902 and synchronous belt 906, it drives the driven shaft 903, causing the cleaning roller 7 to rotate synchronously. When its surface bristles contact the surface of the medicine box, they remove dust and impurities through rotational friction, ensuring the medicine box surface is clean during the acquisition of the stamped image and improving the acquisition quality.
