[0002] The single-station tablet press is a common tablet pressing device. Its working principle is that the punch presses downward to apply pressure to the powdery or granular material on the punch plate, pressing it into tablets. Traditional single-station tablet presses usually rely on manual operation for pressing. The operator applies pressure through a mechanical lever or an electric device and adjusts the pressure and the punch plate to produce tablets of different shapes and sizes.

[0003] Pharmaceutical production has strict requirements for the quality of tablets, including parameters such as tablet hardness and thickness. It is necessary to ensure that the dosage of each tablet is consistent to ensure stable drug efficacy. However, this manual operation method has certain limitations in terms of production efficiency and precision. Manual operation cannot accurately adjust the punch pressure and the relative position of the punch plate during the tablet pressing process, resulting in difficulty in making the hardness and thickness parameters of each tablet consistent, and even the situation of misaligned punching and empty pressing may occur.

[0043] Please refer to Figures 1 to 4, this application proposes a tablet press 10 for pharmaceutical production, which includes a base 100 and a pressing plate 111. The base 100 includes a workbench 110, and the pressing plate 111 is arranged on the workbench 110. A plurality of pressing grooves 1111 are formed on the top surface of the pressing plate 111, and the pressing grooves 1111 are used to place powdery or granular materials. The tablet press 10 for pharmaceutical production further includes a camera 213, a pressing head 232, a driving mechanism, and a control device 300. The camera 213 is located above the pressing plate 111 and faces the camera 213; the pressing head 232 is located above the pressing plate 111, and its axis is oriented towards the pressing plate 111; the driving mechanism is arranged on the base 100, and the driving mechanism can drive the camera 213 and the pressing head 232 to move along the first direction Z or the second direction X, and the driving mechanism can also drive the pressing plate 111 to move along the third direction Y. The first direction Z, the second direction X, and the third direction Y are perpendicular to each other; the control device 300 is electrically connected to the driving mechanism and the camera 213. The control device 300 monitors the distance between the camera 213 and the pressing plate 111 in real time through the camera 213 and obtains the position of each pressing groove 1111. The control device 300 controls the driving mechanism to drive the camera 213, the pressing head 232, and the pressing plate 111 to move, so that the pressing head 232 extends into the specified pressing groove 1111, thereby pressing the powdery or granular material in the pressing groove 1111 into tablets.

[0044] Specifically, the camera 213 is used to monitor the distance between the pressing plate 111 and the pressing head 232 in real time and obtain the position of each pressing groove 1111; the axis of the pressing head 232 is oriented towards the pressing plate 111 and is used to apply pressure to press the powdery or granular material into tablets. The first direction Z, the second direction X, and the third direction Y are perpendicular to each other. The first direction Z refers to the vertical direction, and the second direction X and the third direction Y are horizontal directions. The driving mechanism can drive the camera 213 and the pressing head 232 to move along the first direction Z or the second direction X, and the driving mechanism can also drive the pressing plate 111 to move along the third direction Y. The first direction Z, the second direction X, and the third direction Y are perpendicular to each other, ensuring the positioning and motion control when the pressing head 232 extends into the specified pressing groove 1111. The control device 300 monitors the distance between the pressing plate 111 and the pressing head 232 in real time through the camera 213 and obtains the position of each pressing groove 1111. The control device 300 controls the driving mechanism according to this information, so that the camera 213, the pressing head 232, and the pressing plate 111 move along the set path and position to ensure that the pressing head 232 can accurately extend into the specified pressing groove 1111, thereby pressing the material in the pressing groove 1111 into tablets.

[0045] It should be understood that traditional single-stamping tablet presses rely on manual operation. The operator needs to manually adjust the pressure and the position of the pressure plate 111, resulting in low production efficiency. Due to the limitations of manual operation, it is difficult for traditional tablet presses to ensure that parameters such as the hardness and thickness of each tablet of medicine are consistent. In this application, through the real-time monitoring of the camera 213 and the control of the control device 300, the precise position of the pressing groove 1111 is obtained through the camera 213, and the control device 300 controls the driving mechanism to accurately align the pressing head 232 with the pressing groove 1111, thereby avoiding empty pressing and improving the reliability of production. It can ensure that each tablet of medicine is evenly stressed during the pressing process, with consistent parameters, and avoid quality problems caused by human factors.

[0046] It should be noted that the control device 300 is electrically connected to the camera 213 and the driving mechanism. The camera 213 has high resolution and can clearly capture the positions of each pressing groove 1111. The control device 300 can use the opencv algorithm to identify, measure distances, etc. the positions of each pressing groove 1111 by the camera 213, and send the obtained distances to the control device 300 for processing. In this way, the control device 300 can monitor the distance between the camera 213 and the pressure plate 111 in real time through the camera 213 and obtain the position of each pressing groove 1111, so that the control device 300 can control the driving mechanism to drive the camera 213, the pressing head 232 and the pressure plate 111 to move, so as to extend the pressing head 232 into the specified pressing groove 1111, thereby pressing the powdery or granular material in the pressing groove 1111 into tablets.

[0047] Please refer to Figure 4 , in an embodiment, the distance between the central axis of the pressing head 232 and the camera 213 always remains the same.

[0048] Specifically, maintaining a fixed distance between the pressing head 232 and the camera 213 can ensure that when the camera 213 monitors the positions of the pressure plate 111 and the pressing groove 1111, it can always accurately reflect the actual position of the pressing head 232. During the tablet pressing process, the camera 213 monitors the position of the pressing groove 1111 in real time and feeds back the information to the control device 300. Since the distance between the pressing head 232 and the camera 213 is constant, the control device 300 can more accurately calculate the movement path of the pressing head 232, thereby reducing the position error during the tablet pressing process and ensuring that parameters such as the hardness and thickness of each tablet of medicine are consistent.

[0049] Please refer to Figure 1 and Figure 4In one embodiment, the driving mechanism includes a first driving mechanism 210, a connecting member 220 and a second driving mechanism 230.

The first driving mechanism 210 can drive the connecting member 220 to move along the first direction Z or the second direction X; the second driving mechanism 230 is disposed on the connecting member 220 and movably connected to the pressing head 232. The second driving mechanism 230 can drive the pressing head 232 to move along the first direction Z.

[0050] Specifically, the first driving mechanism 210 can drive the connecting member 220 and drive the camera 213 and the pressing head 232 to move in the first direction Z or the second direction X, the second driving mechanism 230 can drive the pressing head 232 to move in the first direction Z, and the third driving mechanism 240 controls the movement of the workbench 110 in the third direction Y, so as to achieve high-precision positioning. The camera 213 monitors the position of the pressing groove 1111 on the pressing plate 111 in real time, and feeds back the position information to the control device 300. The system can accurately control the movement of the pressing head 232 to accurately align it with the pressing groove 1111, thereby ensuring that the hardness and thickness parameters of each medicine are consistent.

[0051] Please refer to Figure 2 In one embodiment, the driving mechanism further includes a third driving mechanism 240, which is disposed on the base 100 and is transmission-connected to the workbench 110. The third driving mechanism 240 can drive the workbench 110 to move along the third direction Y.

[0052] Specifically, the pressing plate 111 is disposed on the workbench 110, and the third driving mechanism 240 can drive the workbench 110 and drive the pressing plate 111 to move along the third direction Y. This enables the tablet press to flexibly locate the pressing grooves 1111 at different positions, and the pressing head 232 can accurately align with a pressing groove 1111 under the control of the control device 300 to perform precise tableting operations, thereby ensuring that the hardness and thickness parameters of each tablet of medicine are consistent.

The sliding member 212 can freely slide along the extending direction of the slide rail 211 (the first direction Z), and at the same time carry the camera 213 and the pressing head 232. The smooth sliding of the sliding member 212 along the slide rail 211 ensures that the first driving member can drive the sliding member 212 to slide along the extending direction of the slide rail 211, and the vertical movement paths of the camera 213 and the pressing head 232 do not deviate, improving the accuracy of the movement.
