[0033] Compared with the prior art, the present invention has the following technical features and advantages:

[0034] 1. Independence: A unit medicine cabinet is an independent individual. As long as it is connected to the external power supply and communication network, it can independently complete the tasks of adding, taking and dispensing medicine.

[0035] 2. One-key connection mode: The wire trough on the cabinet is a channel reserved for connecting the unit medicine cabinet to the power cord and communication line outside the cabinet. The plug-in terminal in the wire trough can realize the one-key connection mode of power supply and communication of the unit medicine cabinet.

[0036] 3. Adaptability: By adopting different hoppers, upper discharging and medicine taking devices and stirring devices, the machine can adapt to the changes in the shape and bulk density of medicinal materials and complete the work of taking out medicine from different medicinal materials.

[0037] 4. Modularity: Various devices within the unit medicine cabinet, such as the upper discharging device, stirring device, metering push-turn device, metering calibration device, rear door device, dosing door, and cabinet front door, all adopt a modular design and have relatively independent functions. If a device malfunctions, it can be replaced separately, thus achieving rapid replacement and maintenance. In particular, the clamping strip of the upper discharging device matches the slot on the hopper, and the design method of fixing the two components in place with a locking screw and locking hole realizes the rapid assembly, disassembly, and positioning of the upper discharging device.

[0038] 5. Good sealing: The unit medicine cabinet is an independent space, and all joints are sealed. The opening and closing interfaces of frequently opened devices such as the dosing door, cabinet front door, rear door device, and upper cover are sealed with rubber strips, making the unit medicine cabinet box an enclosed space with good anti-mosquito effect.

[0039] 6. Accurate medicine dispensing: By increasing the spacing between the baffles on the composite conveyor belt, the spacing between the medicinal materials on the composite conveyor belt is increased, and the time for the two medicinal materials to pass through the infrared counter is increased, ensuring that the infrared counting can achieve accurate statistics of the number of medicinal materials.

[0040] 7. Fast medicine dispensing speed: Choose a large torque brushless DC motor, and the composite conveyor belt can take out a large amount of medicinal materials with one rotation.

[0041] 8. Eliminate the material bridge phenomenon: Through the operation of the stirring device in the hopper, the medicinal pieces in the hopper are prevented from forming a material bridge during the sliding process, so that the medicinal pieces can slide smoothly along with the medicine taken out by the upper discharging device.

[0042] 9. Self-cleaning capability: A cleaning scraper is designed inside the upper discharging and dispensing device to sweep the drug residue and dust attached to the inside of the composite tape through the residue opening into the drug residue cover, where they are eventually accumulated in the drug residue bag. You only need to clean the drug residue in the drug residue bag regularly.

[0043] 10. Good heat dissipation: The front door of the cabinet is equipped with a breathable mesh at the position of the control panel to ensure the heat dissipation of the control panel; the rear end of the cabinet is equipped with an air intake mesh with a dustproof net, and the front end of the cabinet is equipped with a heat dissipation exhaust mesh. An exhaust fan is installed on the mesh. When the exhaust fan is running, fresh air enters from the air intake mesh at the rear end of the cabinet, taking away the heat generated by the middle motor, and then the hot air is discharged through the exhaust fan, thereby achieving the purpose of heat dissipation.

[0044] 11. The operating status of the unit medicine cabinet is obvious: the operating status of the unit medicine cabinet can be judged by observing the colors of the medicine shortage indicator light and the fault indicator light on the front door of the cabinet.

[0045] 12. Advantages of Split-Unit Medicine Cabinets: Split-unit medicine cabinets can separate the hopper from the cabinet. The hopper positioning pins on the hopper match the hopper positioning slots on the cabinet for positioning assembly, and then the hopper is fastened to the cabinet through the fixing holes on the cabinet. This makes it easy to assemble and disassemble the hopper and cabinet, making it convenient to replace other types of hoppers without replacing the cabinet.

[0046] 13. Prevent medicine from being scattered when adding medicine: There are side baffles on the left and right sides of the dosing door to prevent the medicinal pieces from accidentally falling outside the hopper during the dosing process; the side baffles of the dosing door are inserted into the baffle box of the dosing door, and a sealing brush strip is set in the side baffle box to prevent the medicinal pieces from accidentally falling into the side baffle box.

[0047] 14. Prevent pollution: The control panel is covered with a control panel box, which isolates the control panel from the internal space of the cabinet and prevents the medicine dust in the cabinet from contaminating the control panel; some unit medicine cabinets may generate more medicine dust during the process of taking medicine, which will pollute the interior of the unit medicine cabinet. To prevent this kind of medicine dust pollution, a dust-proof isolation board (or dust-proof isolation mesh) can be set to divide the interior of the cabinet into two areas. The upper one is the heat dissipation area and the lower one is the medicine outlet area, which reduces the space contaminated by medicine dust. The two areas are isolated and do not affect each other. The medicine dust generated in the medicine outlet area with larger medicine dust will not pollute the heat dissipation area. The medicine outlet area should be cleaned regularly during use.

[0048] 15. Manual unlocking: The electric locks of the cabinet front door and the dosing door are designed with manual mechanical unlocking parts. In the event of failure of the electric lock, the cabinet front door and the dosing door can be opened manually. BRIEF DESCRIPTION OF THE DRAWINGS

[0115] The control method of the metering, pushing and flipping device comprises the following steps:

[0116] (1) Before the weighing operation, the upper system controls the electronic scale control circuit board to reset the measurement data to zero;

[0117] (2) The weighing pan receives the medicinal material slices output by the medicine dispensing device;

[0118] (3) The electronic scale sensor under the scale pan detects the weight of the medicinal materials in the scale pan in real time, and uploads the weight data to the upper system through the electronic scale control circuit board in real time;

[0119] (4) When the weight of the medicinal material slices reaches the required weight, the material taking device stops taking out the material, and the metering and pushing flipping device waits for the next action instruction;

[0120] (5) The metering push flipping device receives the dumping command from the superior system, and the motor of the metering push flipping device drives the screw to rotate, pushing the T-type flange nut to move, and the T-type flange nut drives the slider to move linearly on the slide rail; the slider is connected to the scale pan turntable, and the slider drives the scale pan turntable to move linearly, thereby driving the scale pan to move linearly; when the scale pan moves to a certain position, the gear on the scale pan turntable engages with the rack, so that the scale pan has a flipping motion on the basis of linear motion; when the scale pan moves linearly to the specified position, the limit lever touches the limit touch switch and stops moving. At this time, the flipping motion of the scale pan just flips the scale pan to a certain angle, so that the medicinal materials in the scale pan are dumped out, and the medicine is discharged; after the scale pan remains in the dumping state for a few seconds, the motor rotates in the opposite direction, driving the scale pan to rotate back to the horizontal state first, and then make a linear motion back to the original starting point. After the limit lever touches the reset touch switch, the motor stops;

[0121] (6) The scale pan is reset and the measurement is cleared to zero, waiting for the next operation.

[0122] Working process of this unit cabinet:

[0123] Dosing:

[0124] 1. The control panel receives the unlocking instruction of the dosing door from the upper system. The control panel controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops up and opens under the action of the spring sheet and remains open.

[0125] 2. The user puts the medicinal slices into the hopper.

[0126] 3. The user manually closes the dosing door and the dosing is completed.

[0127] Get medicine:

[0128] After the control panel receives the medicine-picking instruction from the superior system, it controls the stirring device to start stirring, controls the infrared counter to start counting, and controls the upper discharging and medicine-taking device to start moving. The baffle on the composite conveyor belt drives the medicinal slices, passes through the medicine-limiting shrapnel, and blocks the excess slices outside the inner medicine cover, ensuring that only one medicinal slice is taken out by one baffle, so that the medicinal slices are discharged one by one in an orderly manner. When the circular medicinal slices pass through the infrared counter on the rear cover, the control panel counts through the infrared counter, and the medicinal slices finally fall into the weighing pan. At this time, the weighing pan does not measure, but only serves to receive, push, and flip the medicine. When the medicinal slices in the medicine tray reach the required number, the upper discharging and medicine-taking device stops moving and the stirring device stops stirring.

[0129] Dispensing medicine:

[0130] 1. After the control system receives the medicine dispensing instruction from the superior system, the control panel controls the motor in the rear door device to rotate outward, and drives the connecting rod and the sensor dial to rotate outward. The connecting rod lifts the upper cover plate of the rear door and drives the lower cover plate of the rear door to open. When the sensor dial rotates to a certain angle, the sensor dial touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open.

[0131] 2. The control panel controls the action of the rear door device while controlling the action of the push-turn device. The motor in the push-turn device starts to rotate, pushing the scale plate toward the rear door. After moving horizontally for a certain distance, the gear and rack on the scale plate engage, so that the scale plate can flip over on the basis of horizontal movement, and begins to dump the medicinal materials. After the scale plate flips to a certain angle and touches the limit switch, the motor stops rotating and the scale plate stops flipping. At this time, the medicinal materials can be completely dumped out.

[0132] 3. After the scale pan maintains the tilting angle for a certain period of time, the control panel controls the motor in the push-turn device to start rotating in the opposite direction, the scale pan rotates back to a horizontal state, and then moves back horizontally. After touching the limit switch, the motor stops rotating and the scale pan resets.

[0133] 4. When the push-turn device is reset, the control panel controls the motor in the rear door device to rotate inward, and drives the connecting rod and the sensor dial to rotate inward. The connecting rod drives the upper and lower sealing plates of the rear door to rotate and close. When the sensor dial rotates to a certain angle, the sensor dial touches the rear door reset sensor, the motor stops rotating, and the rear door device is in the closed state.

[0134] 5. Wait for the next dose of medicine.

1. The control panel receives the unlocking instruction for the dosing door from the upper system. The control panel controls the electric lock of the dosing door to be powered on and unlocked. The dosing door automatically pops up and opens under the action of the spring sheet and remains open.

2. The user puts the medicinal slices into the hopper; 3. The user manually closes the dosing door and the dosing is completed; Get medicine: After the control panel receives the medicine picking instruction from the superior system, the control panel controls the stirring device to start stirring, controls the infrared counter to start counting, and controls the upper discharging and medicine taking device to start action; the baffle on the stainless steel baffle-type composite conveyor belt drives the medicinal slices, passes through the medicine limiting shrapnel, and blocks the excess medicinal slices outside the inner medicine cover, ensuring that only one medicinal slice is taken out by one baffle, so that the medicinal slices are discharged one by one in an orderly manner; when the round medicinal slices pass through the infrared counter on the rear cover, the control panel counts through the infrared counter, and the medicinal slices finally fall into the weighing pan; at this time, the weighing pan does not measure, but only serves to receive, push, and flip the medicine. After the medicinal slices in the medicine tray reach the required number, the upper discharging and medicine taking device stops moving and the stirring device stops stirring; Dispensing medicine:

1. After the control system receives the medicine dispensing command from the upper system, the control panel controls the motor in the rear door device to rotate outward, driving the connecting rod and the sensor dial to rotate outward. The connecting rod lifts the upper rear door cover and drives the lower rear door cover to open. When the sensor dial rotates to a certain angle, the sensor dial touches the rear door limit sensor, the motor stops rotating, and the rear door device remains open.

2. The control panel controls the movement of the rear door device while controlling the movement of the metering, pushing and flipping device. The motor in the metering, pushing and flipping device starts to rotate, pushing the scale plate toward the rear door. After moving horizontally for a certain distance, the spur gear on the scale plate engages with the rack, so that the scale plate can flip over on the basis of horizontal movement, and begins to dump the medicinal materials. After the scale plate flips to a certain angle and touches the limit switch, the motor stops rotating and the scale plate stops flipping. At this time, the medicinal materials can be completely dumped out.

3. After the scale pan maintains the tilting angle for a certain period of time, the control panel controls the motor in the metering push-turning device to start rotating in the reverse direction, the scale pan rotates back to a horizontal state, and then moves back horizontally. When it touches the limit switch, the motor stops rotating and the scale pan resets; 4. When the metering push-turn device is reset, the control panel controls the motor in the rear door device to rotate inward, and drives the connecting rod and the sensor dial to rotate inward. The connecting rod drives the upper and lower sealing plates of the rear door to rotate and close. When the sensor dial rotates to a certain angle, the sensor dial touches the rear door reset sensor, the motor stops rotating, and the rear door device is in the closed state.

5. Wait for the next dose of medicine.
