Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The tablet appearance inspection device with a dustproof structure shown includes a frame 14 and a conveyor belt 4 installed inside the frame 14;

[0024] A dust cover 5 is installed on the upper side of the conveyor belt 4;

[0025] Cameras 11 are installed on the lower inner wall of the dust cover 5, near the left and right sides respectively;

[0026] A display screen 10 is installed on the upper outer wall of the dust cover 5 to display data information during shooting. The dust cover 5 is installed on the upper side of the conveyor belt 4, which can effectively prevent external dust and debris from entering the detection area, thereby maintaining hygiene and the normal operation of the equipment. The camera 11 is used to capture images of the tablets passing through the conveyor belt 4 in real time. The camera 11 can be equipped with a high-resolution image sensor, which can capture the subtle surface features, color, shape, and possible defects of the tablets. When the tablets pass under the camera 11, the camera 11 will automatically capture images of the tablets and transmit the image data to an internal image processing system or computer for analysis. This system can apply machine vision algorithms and deep learning technology to automatically identify and judge the appearance quality of the tablets. The display screen 10 is used to display the captured images and data information during shooting in real time.

[0027] Rollers 16 are provided on the upper inner wall of the conveyor belt 4, near the left and right sides respectively, to form an inclined surface on the surface of the conveyor belt 4. A guide plate 19 is provided between the inner walls of the front and rear ends of the fixed frame 14 and on the left side of the roller 16. A guide plate 20 is fixedly connected to the outer wall of the left end of the guide plate 19 to change the position of the tablet. When the medicine is transported on the conveyor belt 4, the conveyor belt 4 forms an upward triangular ramp under the restriction of the roller 16. When the medicine moves from right to left, it will pass through the ramp and be guided to the guide plate 19. Under the push of the conveyor belt 4, the medicine slides down the guide plate 20 and flips when it slides down onto the conveyor belt 4.

[0028] like Figure 2 and Figure 4 As shown, multiple positioning rods a15 are fixedly connected between the inner walls of the front and rear ends of the fixed frame 14 to limit the position of the roller 16. Multiple positioning rods b17 are fixedly connected to the inner walls of the front and rear ends of the fixed frame 14 and to the left and right sides of the roller 16, respectively. One end of each positioning rod b17 is fitted with a pressure rod sleeve 18 to limit the tilt angle of the conveyor belt 4. A stop block is fixedly connected to the lowest side of the outer wall of the left end of each of the two guide plates 19.

[0029] Positioning rod a15 restricts the position of roller 16 to ensure the positioning accuracy of roller 16 on conveyor belt 4. By setting pressure rod sleeve 18 and positioning rod b17 on the left and right sides of roller 16, the curvature of the lower left and right ends of the top of conveyor belt 4 lifted by roller 16 can be restricted. A stop is set at the left end of guide plate 19, which can temporarily stop the tablet when it slides down according to guide plate 19, and then flip the tablet to increase the accuracy of successful tablet flipping.

[0030] like Figure 1 As shown, a base 1 is fixedly connected to the lower outer wall of the fixed frame 14, and a drive motor 2 is fixedly connected to the rear outer wall of the fixed frame 14. The drive motor 2 is electrically connected to an external power source. A drive shaft 3 is fixedly connected to the front outer wall of the drive motor 2 to drive the conveyor belt 4 to rotate. Multiple transmission shafts 13 are equidistantly arranged between the inner walls of the front and rear ends of the fixed frame 14.

[0031] Fixed to the rear outer wall of the fixed frame 14, it is responsible for the power source of the entire system. Fixed to the front outer wall of the drive motor 2, it transmits the power of the drive motor 2 to the conveyor belt 4. The transmission shaft 13 is used to connect and distribute kinetic energy, so that the conveyor belt 4 can transmit force evenly and ensure that the tension and speed of the conveyor belt 4 remain consistent throughout the entire conveying process.

[0032] like Figure 1As shown, a control cabinet 9 is fixedly connected to the upper outer wall of the dust cover 5, an air pump 8 is fixedly connected to the right outer wall of the control cabinet 9, an air supply pipe 7 is fixedly connected to the right outer wall of the air pump 8, and a nozzle 6 is fixedly connected to the other end of the air supply pipe 7 to spray gas onto the surface of the medicine. Lighting lamps 12 are installed on the lower outer walls of the two cameras 11, respectively, close to the left and right sides.

[0033] The control cabinet 9 is used to centrally control all the devices in the system, including the air pump 8, the lighting 12, and the camera 11. The display screen 10 at the front of the control cabinet 9 serves as the operation panel, allowing users to set, monitor, and adjust the operating parameters of the devices. When the air pump 8 is working, it draws in outside air and sprays it out after filtering or processing. The nozzle 6 sprays air or a specific gas onto the surface of the medicine. The sprayed gas helps to remove tiny dust or particles attached to the surface of the medicine, ensuring that the medicine is clean when it is filmed by the camera 11. The lighting 12 ensures that the tablets receive sufficient and uniform lighting when the camera is filming, reducing the effects of shadows and highlights.

[0034] The implementation principle of this embodiment is as follows: A dust cover 5 is provided on the upper side of the conveyor belt 4, which can effectively prevent external dust and debris from entering the detection area, thereby maintaining hygiene and the normal operation of the equipment. The camera 11 is used to capture images of the tablets passing through the conveyor belt 4 in real time. The camera 11 can be equipped with a high-resolution image sensor, which can capture the subtle surface features, color, shape, and possible defects of the tablets. When the tablets pass under the camera 11, the camera 11 automatically captures the image of the tablets and transmits the image data to an internal image processing system or computer for analysis. This system can apply machine vision algorithms and deep learning technology to automatically identify and judge the appearance quality of the tablets. The display screen 10 is used to display the captured images and data information at the time of capture in real time. When the medicine is transported on the conveyor belt 4, the conveyor belt 4 forms an upward triangular ramp under the restriction of the roller 16. When the medicine moves from right to left, it will pass through the ramp and be guided to the guide plate 19. Under the push of the conveyor belt 4, the medicine slides down the guide plate 20 and is flipped when it slides down onto the conveyor belt 4.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
