[0026] Refer to Figure 1 and Figure 2 As shown, the tilting mechanism includes a rotating shaft 107 fixed to the mounting bracket 101 and a tilting drive element 108 for driving the rotating shaft 107 to rotate. The tilting mechanism also includes a mounting base plate 106; the tilting drive element 108 is fixed to the mounting base plate 106 via a bracket, and the rotating shaft 107 is mounted on the mounting base plate 106 via a bearing seat. To control the tilting stroke of the tilting mechanism, a first sensing plate 1072 is fixed to the rotating shaft 107, and two first slotted photoelectric switches 1071 are provided on the side of the bearing seat near the sensing plate. The first sensing plate 1072 cooperates with the two first slotted photoelectric switches 1071 to cause the material box 7 on the tilting mechanism to tilt between a horizontal state and a forward tilting state. In this embodiment, the tilting drive element 108 includes a stepper motor, a servo planetary reducer, and a coupling.
[0027] Refer to Figure 2As shown, the gripper drive mechanism 105 includes a gripper drive element 1054 and a guide assembly fixed to the gripper 104; the guide assembly includes a slide rail 1051 fixed to the bottom side of the mounting frame 101 and a slider 1052 having a left-right sliding degree of freedom along the slide rail 1051; the gripper 104 is fixed to the slider 1052 on the corresponding side; the gripper drive element 1054 is fixed to the bottom side of the mounting frame 101 and located in the area between the two guide assemblies; the rotation output end of the gripper drive element 1054 is connected to the two sliders 1052 or the two grippers 104 respectively through a connecting rod assembly 1053, for converting the rotational power of the gripper drive element 1054 into the force of the slider 1052 sliding left and right along the slide rail 1051. In this embodiment, two second slotted photoelectric switches 1055 are provided on the side of one of the guide components. The gripper 104 has a protrusion corresponding to the second slotted photoelectric switch as a second sensing plate 1056. The stroke control of the gripper's left and right movement is realized through the cooperation of the second sensing plate and the second slotted photoelectric switch. In addition, the gripper driving element adopts a stepper motor.
[0028] Refer to Figure 1 As shown, the top side of the material bin baffle assembly 103 has a rearwardly bent first limiting part 1031; the top side of the gripper 104 has an inwardly bent second limiting part 1041; the first limiting part 1031 and the second limiting part 1041 are used to form the upper limit of the material bin 7. Through the design of the first limiting part 1031 and the second limiting part 1041, the material bin can be firmly fixed, and the medicine bin will not fall out when tilted. With the cooperation of the two first slotted photoelectric switches 1071 and the first sensing plate 1072, it can be tilted at a large angle.
[0029] Refer to Figure 1 As shown, a sensor 1032 for sensing whether the material box is in position is also provided on the side of the material box baffle assembly 103. In this embodiment, the sensor 1032 is a through-beam photoelectric sensor; when the material box is sent to the front end by the first material box conveyor line 102, it will be blocked by the material box baffle assembly 103, which will trigger the sensor 1032. The gripper drive mechanism 105 will be activated in response to the trigger signal of the sensor 1032, so that the two grippers will close inward to clamp the material box.
[0030] Refer to Figure 1 As shown, the inner side of the gripper is also provided with a flexible part 1042, which is used to flexibly contact the material box when gripping it and increase the friction between the gripper and the material box. The flexible part 1042 can be made of silicone.
[0031] One embodiment of the material bin tilting mechanism, such as Figure 1As shown, the first material box conveyor line is horizontal, waiting for the material box to enter. When the material box enters, the first material box conveyor line starts and conveys the material box forward. When the material box reaches the material box baffle assembly, the sensor is triggered, and the second material box conveyor line stops. At this time, the front edge of the top of the material box is below the first limiting part. At the same time, the gripper drive mechanism starts, the output end of the gripper drive element rotates, driving the linkage assembly. The linkage assembly pulls the slider relative to the slide rail towards the center, thereby driving the gripper to close towards the center until the second sensing plate triggers the second slot-shaped photoelectric switch near the inside. At this time, the flexible part on the gripper contacts the material box, and the left and right edges of the top of the material box are below the second limiting part of the gripper. Then, the tilting drive element... The rotating shaft drives the gripper to rotate, causing the gripper and the hopper to flip forward together until the first sensor triggers the first slotted photoelectric switch (controlling the tilting state); the medicine in the hopper is poured out; then, the tilting drive element reverses, causing the hopper to flip until the first sensor triggers the first slotted photoelectric switch (controlling the horizontal state), and the hopper returns to the horizontal state. The output end of the gripper drive element rotates in the opposite direction, driving the linkage assembly, which pushes the slider to move outward relative to the slide rail, thereby causing the gripper to separate until the second sensor triggers the second slotted photoelectric switch near the outer side. At this point, the gripper disengages from the hopper; then, the first hopper conveyor line reverses its direction, and the empty hopper is removed and stored; the first hopper conveyor line awaits the entry of a new hopper.

[0040] Taking the automatic medication replenishment system of Example 3 as an example, the medication replenishment machine is connected to the dispensing machine. When the dispensing machine is low on stock, the replenishment machine replenishes the medication. Simultaneously, the medication conveyor buffer automatically supplies the replenishment machine with medication, which can be stacked haphazardly in the buffer. The medication conveyor buffer is connected to a hopper tilting mechanism, which in turn connects to a second hopper conveyor line, which in turn connects to a hopper handling robot. When the medication in the buffer is insufficient, the hopper handling robot retrieves medication from the storage rack. The first conveyor line sends the medicine bins to the second conveyor line, which then delivers them to the tilting mechanism. The tilting mechanism pours the medicine from the bins into the medicine conveyor line's buffer pool. The tilting mechanism also has a translation function, allowing the medicine to be poured to different locations within the buffer pool, preventing excessive accumulation of medicine in certain areas. The storage racks are typically located in air-conditioned, cool storage rooms. The second conveyor line connects the inside and outside of the cool storage room, facilitating the storage and transfer of medicines.
