[0002] As the treasure of Chinese medicine, traditional Chinese medicine has played a huge role in the health of the Chinese people and the prosperity of the nation over its thousands of years of history. However, the traditional Chinese medicine industry itself still has room for improvement and enhancement in many aspects.

[0003] Traditional Chinese medicine is usually dispensed manually, that is, when a patient goes to a pharmacy to get medicine, the pharmacist will go to the drawer of the Chinese medicine cabinet to manually take out the medicine, weigh the medicine, and prepare the prescription for the patient according to the prescription. This manual dispensing method has the disadvantages of low efficiency, easy to make mistakes, time-consuming and labor-intensive.

[0036] When the blade is cutting, the Chinese herbal medicine pieces are placed between the lower blade seat, the upper pressing plate and the side baffle, and the blade teeth perform translational and rotational cutting on the Chinese herbal medicine pieces below the cutting edge along the cutting edge root toward the cutting edge tip.

[0037] The metrology calibration method of the metrology calibration device comprises the following steps:

[0038] The control system issues a "measurement correction" command;

[0039] The unit medicine cabinet control panel controls the metering push flip device to reset the weighing pan to zero;

[0040] The control panel of the unit medicine cabinet controls the operation of the motor of the metering and calibration device, driving the winding rod of the mainspring wire and the winding device of the weight wire to rotate;

[0041] The weight line reel releases the weight line to gently put the weight down, and at the same time the weight releases the reset touch switch, and the unit medicine cabinet control board detects that the weight has moved;

[0042] While the weight is moving, the winding rod of the mainspring winds up the mainspring, pulls the mainspring out of the mainspring disc, turns it through the pulley, passes through the small hole at one end of the spring sheet, and winds it into the wire groove in the winding rod of the mainspring;

[0043] The weight continues to drop until it falls into the scale plate of the metering push flip device. The weight is no longer subject to any pulling force. The motor continues to work for a certain period of time and then stops. The weight line winder continues to rotate for a certain period of time to release more weight line, so that the extra weight line is suspended in the air so that it does not affect the accuracy of the weight. The length of "the motor continues to work for a certain period of time" is controlled by the positioning node on the clockwork line and needs to be set in advance.

[0044] After the weight falls into the scale plate of the metering push-turn device, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating.

[0045] When the weight of the specified weight of the metering calibration device falls into the scale pan in the metering push flip device, the metering device of the metering push flip device will read the metering data of the weight in the current scale pan and send it to the unit medicine cabinet control board, and the unit medicine cabinet control board will compare the metering data with the weight data of the weight entered in advance. If the comparison error is within the specified error range, the metering device of the metering push flip device is determined to be qualified. If the comparison error exceeds the specified error range, the metering device of the metering push flip device is unqualified, and the unit medicine cabinet control board will alarm the superior system, prompting that the metering device in the metering push flip device needs to be replaced;

[0046] The control system controls the metering push device to automatically control the motor to rotate in the opposite direction after the metering calibration is completed. The weight line winder gathers the weight line to lift the weight, and the winding line winding rod releases the spring line. The spring line is pulled by the spring and is wound into the spring disk. The positioning node goes back with the spring line, and the spring sheet rebounds to release the weight in place to touch the switch. The control system detects the weight and starts the return journey.

[0047] The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the paddle of the weight reset touch switch is pressed. The system detects that the weight reaches the initial fixed position and controls the motor to stop rotating.

[0048] The metrological calibration is completed.

[0049] Compared with the prior art, the present invention has the following technical features and advantages:

[0050] 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.

[0051] 2. One-key connection mode: The wire trough on the cabinet is a reserved channel for the unit medicine cabinet to connect the power cord and communication line outside the cabinet. The one-key connection mode of the unit medicine cabinet power supply and communication can be realized through the plug-in terminal in the wire trough.

[0052] 3. Adaptability: By using different hoppers, bottom discharging and medicine taking devices and different weight counterweights, the shape and bulk density of medicinal materials can be adapted to complete the work of taking out medicine from different medicinal materials.

[0053] 4. Modularity: All kinds of devices in the unit medicine cabinet, such as the lower discharging and taking medicine device, metering push and flip, metering calibration device, rear door device, dosing door, cabinet front door, etc., are modularly designed and have relatively independent functions. If a device fails, it can be replaced separately, thereby realizing rapid replacement and maintenance. In particular, the card strip of the lower discharging and taking medicine device cooperates with the card slot on the hopper, and the design method of positioning and fixing the two components with locking screws and locking holes is adopted, which realizes the rapid assembly and disassembly and positioning of the lower discharging and taking medicine device.

[0054] 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 medicine adding door, cabinet front door, rear door device, and upper cover plate are sealed with rubber strips, making the unit medicine cabinet box an enclosed space with good mosquito-proof effect.

[0055] 6. Accurate medicine discharging: The lower discharging and medicine taking device adopts a special composite conveyor belt. Through the careful design of the width of the composite conveyor belt, the height and size of the steel teeth, and the action of the shearing mechanism and the elastic briquetting mechanism, the medicinal pieces that are difficult to separate are cut off and smoothly dropped into the weighing pan, thereby achieving the purpose of accurate medicine discharging. The elastic briquetting mechanism can be adjusted up and down according to the number of medicinal pieces at the medicine outlet, which can effectively compress the medicinal pieces.

[0056] 7. Fast medicine dispensing speed: The entire medicine picking and shearing device seems complicated, but it is closely coordinated, fast and efficient, and can meet the purpose of quickly picking up medicinal materials.

[0057] 8. Eliminate the phenomenon of material bridge: The pressing plate mechanism, under the action of its own weight and the counterweight block, compacts the fluffy medicinal slices, so that the medicinal slices in the hopper slide down as the medicinal slices are taken out, thereby avoiding the phenomenon of empty bridges in the medicinal slices.

[0058] 9. Self-cleaning capability: A cleaning scraper is designed inside the lower discharging and drug taking device, which can clean the drug residue and drug dust attached to the inside of the composite tape through the residue opening into the drug residue cover, and finally accumulate in the drug residue bag. You only need to clean the drug residue in the drug residue bag regularly.

[0059] 10. Good heat dissipation: A breathable mesh is set at the position of the control panel on the front door of the cabinet to ensure the heat dissipation of the control panel; an air intake mesh with a dustproof net is set at the rear end of the cabinet, and a heat dissipation exhaust mesh is set at the front end of the cabinet. 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.

[0060] 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 color of the medicine shortage indicator light and the fault indicator light on the front door of the cabinet.

[0061] 12. Advantages of split-unit medicine cabinet: Split-unit medicine cabinet can separate the hopper from the cabinet box. The hopper positioning pin on the hopper and the hopper positioning slot on the cabinet box are assembled together for positioning, and then fastened to the hopper through the fixing holes on the cabinet box. Therefore, the hopper and the cabinet box are easy to assemble and disassemble, and it is convenient to replace other types of hoppers without changing the cabinet box.

[0062] 13. Prevent medicine from being scattered during dosing: Side baffles are set on the left and right sides of the dosing door to prevent the medicinal pieces from accidentally falling out of 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 of the dosing door to prevent the medicinal pieces from accidentally falling into the side baffle box.

[0063] 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 drug dust in the cabinet from contaminating the control panel; some unit medicine cabinets may generate more drug dust during the process of taking the medicinal pieces, which will pollute the inside of the unit medicine cabinet. To prevent this kind of drug dust pollution, a dust-proof isolation plate (or dust-proof isolation mesh) can be set to divide the inside of the cabinet into two areas, the upper one is the heat dissipation area, and the lower one is the drug output area, so as to reduce the space contaminated by drug dust. The two areas are isolated from each other and do not affect each other. The drug dust generated in the drug output area with larger drug dust will not pollute the heat dissipation area. The drug output area should be cleaned regularly during use.

[0064] 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.

[0065] 16. Regularly correct metering errors: A metering correction device is installed above the corresponding metering push and flip device in the unit medicine cabinet. The superior system can regularly control the metering correction device through the unit medicine cabinet control board driver to perform metering correction on the metering accuracy of the metering push and flip device, so as to ensure the metering accuracy of the metering push and flip device.

[0066] 17. Airtightness of the hopper: When the pressure plate mechanism moves up and down, the sealing steel belt moves up and down with the pressure plate mechanism, and the steel belt pressure plate always presses the sealing steel belt, so that the sealing steel belt covers the strip groove of the hopper to achieve the effect of sealing the hopper.

[0067] 18. Applicable medicinal material types: The composite conveyor belt type lower discharge belt shearing bulk Chinese herbal medicine piece unit medicine cabinet is suitable for medicinal materials with light weight, clumping medicinal materials, and serious entanglement between single medicinal materials, such as loofah, bamboo rubbing, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0140] The rear plate of the hopper is an oblique plate, and the upper and lower outer walls of the strip groove 56 of the rear plate of the hopper are respectively installed with an upper roller 50a and a lower roller 50b, and the annular steel belt 50c used to seal the strip groove is hung on the upper roller and the lower roller; the structure of the hinge pressure plate assembly 800 is as follows: a plurality of pressure rods 802 are fixed on a horizontal bar along the longitudinal direction and at equal intervals, and a loose-leaf pressure plate 803 is installed at the front of each pressure rod via a torsion spring 804, and a counterweight block 805 is transversely fixed to the rear of all pressure rods, and when no external force is applied, the loose-leaf pressure plates of all pressure rods are in the torsion spring state. Under the force, an integral pressure plate adjacent to each other is formed. A fixing seat 801 used for fixing with a lifting mechanism via bolts is fixed on the longitudinal fixing shaft fixed in the middle of the horizontal bar. A lowering limit switch 709 and a lifting limit switch 710 are installed on the fixing seat. A clamping mechanism for the grab plate 706 to grab is vertically arranged on the horizontal plate of the fixing seat: a truncated table 707 and a disc are respectively provided at the upper and lower ends of the middle axis of the bayonet fixing shaft 722, and an inverted truncated table 708 symmetrical to the shape of the truncated table, i.e., a movable bayonet shaft 723, is movably sleeved on the middle axis;

The weight line passes through the weight line guide ring, the circular hole on the top plate of the base and the weight reset fixing seat in sequence downward along the weight line reel, and a weight 3010 for measurement correction is fixedly connected to the lower end; The spring disk 3014 is mounted on a vertical plate 3015 fixed to the bottom surface of the top plate of the base, and the pulley 3011 is fixed on the vertical plate 3015; the left end of the spring sheet 3013 is fixed to the bottom surface of the top plate of the base by a screw; the spring line passes vertically downward along the spring line winding rod through the through hole on the top plate of the base and the lower end of the small hole on the right end of the spring sheet, and then passes around the pulley and connects to the spring of the spring disk in the horizontal left direction; the bottom surface of the top plate of the base is installed with a weight in place touch switch 306 and a weight reset touch switch 307; a spring line is provided on the spring line below the spring sheet. A positioning section 3018 is provided which cannot pass through the small hole at the right end of the spring sheet; the weighing pan 3016 is arranged directly below the weight; when the weight falls into the weighing pan along with the weight line under the positive drive of the motor, at the same time, the positioning section of the clockwork line moves upward and triggers the weight in place touch switch by lifting the spring sheet, thereby controlling the motor to stop rotating; when the weight moves upward along with the weight line and enters the weight reset fixing seat and triggers the weight reset touch switch at the same time under the reverse drive of the motor, the clockwork line moves downward under the tension of the clockwork spring, and the positioning section of the clockwork line moves downward and resets ( Fig.58 , Fig.59 , Fig.60 ).

[0158] The metrology calibration method of the metrology calibration device comprises the following steps:

[0159] (1) The control system issues a "measurement calibration" command;

[0160] (2) The unit medicine cabinet control panel controls the metering push flip device to reset the scale to zero;

[0161] (3) The unit medicine cabinet control panel controls the operation of the motor of the metering calibration device, driving the winding rod of the mainspring wire and the winding device of the weight wire to rotate;

[0162] (4) The weight line reel releases the weight line and gently puts the weight down. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control panel detects that the weight has moved;

[0163] (5) As the weight moves, the winding rod reels in the winding wire, pulls the winding wire out of the winding disc, turns it through the pulley, passes through the small hole at one end of the spring sheet, and winds it into the wire groove in the winding rod;

[0164] (6) The weight continues to drop until it falls into the scale pan of the metering push-turn device. The weight is no longer subject to any pulling force. The motor continues to work for a certain period of time and then stops. The weight line winder continues to rotate for a certain period of time to release more weight line, leaving the extra weight line hanging in the air so that it does not affect the accuracy of the weight. The length of "the motor continues to work for a certain period of time" is controlled by the positioning node on the clockwork line and needs to be set in advance.

[0165] (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating;

[0166] (8) When the weight of the specified weight of the metering calibration device falls into the scale pan of the metering push flip device, the metering device of the metering push flip device will read the metering data of the weight in the current scale pan and send it to the unit medicine cabinet control board. The unit medicine cabinet control board compares the metering data with the weight data of the weight entered in advance. If the comparison error is within the specified error range, the metering device of the metering push flip device is determined to be qualified. If the comparison error exceeds the specified error range, the metering device of the metering push flip device is unqualified, and the unit medicine cabinet control board alarms the superior system, prompting that the metering device in the metering push flip device needs to be replaced;

[0167] (9) The control system controls the metering push device to automatically control the motor to rotate in the opposite direction after the metering calibration is completed. The weight line winder reels in the weight line to lift the weight, and the winding line rod releases the winding line. The winding line is pulled by the spring and wound into the spring disk. The positioning node goes back with the spring line, and the spring sheet rebounds to release the weight in place to touch the switch. The control system detects that the weight starts to return;

[0168] (10) The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the paddle of the weight reset touch switch is pressed. The system detects that the weight reaches the initial fixed position and controls the motor to stop rotating.

[0169] (11) Metrology calibration is completed.

[0183] Working process:

[0184] Dosing:

[0185] 1. The control panel receives the instruction from the upper system to unlock the dosing door.

[0186] 2. The control board driver controls the reduction motor in the lifting mechanism to rotate, and the gear drives the screw to rotate, and the screw pushes the grab plate fixed on the screw nut to move downward. When the grab plate moves downward to pass through the grab plate fixing tower cap (i.e., the round table 707), it touches the lifting limit switch, and the control board driver controls the reduction motor to stop rotating, and the grab plate stops moving downward. At this time, the grab plate nail pops out under the action of the grab plate spring and jams the grab plate fixing tower cap, so that the grabbing action of the grab plate is completed.

[0187] 3. When the grabbing plate completes the grabbing action, the control panel driver controls the reduction motor in the lifting mechanism to immediately start reverse rotation, the grabbing plate moves upward, and at the same time drives the pressing plate mechanism to move upward together, and drives the sealing steel belt to rotate in the opposite direction to ensure the sealing of the hopper.

[0188] 4. When the pressure plate mechanism is lifted to the top of the hopper, the hinge pressure plate in the pressure plate mechanism enters the hinge folding frame, and the hinge pressure plate is folded. At this time, the grab plate touches the limit switch of the lifting mechanism, and the control board driver controls the reduction motor to stop moving, and the lifting mechanism and the pressure plate mechanism stop rising.

[0189] 5. The control panel driver 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 in the open state.

[0190] 6. The user loads the medicinal pieces into the hopper.

[0191] 7. The user manually closes the dosing door.

[0192] 8. The reduction motor of the lifting mechanism rotates, the grab plate moves downward, and the pressing plate mechanism moves downward accordingly under the action of its own weight and the grab plate. The hinge pressing plate withdraws from the hinge folding frame, and the hinge baffle expands into a 180° flat plate under the action of the torsion spring. As the grab plate and the pressing plate mechanism continue to move downward, the hinge pressing plate contacts the top of the medicinal materials in the hopper until the full weight of the pressing plate mechanism presses the medicinal materials. At this time, the pressing plate mechanism will not move downward.

[0193] 15. After the pressure plate mechanism stops moving, the lifting mechanism continues to move downward, and the grab plate moves downward with the lifting mechanism through the grab plate movable tower cap, i.e., the inverted truncated table 708. After the grab plate passes through the grab plate movable tower cap, it touches the lowering limit switch, and the reduction motor starts to rotate in the opposite direction. The lifting mechanism starts to move upward, and the grab plate moves upward with the lifting mechanism through the grab plate movable tower cap and the grab plate fixed tower cap, so that the lifting mechanism grab plate is separated from the pressure plate mechanism, and the release action of the grab plate is completed. The lifting mechanism continues to move upward, and the grab plate touches the lifting mechanism limit switch. The control board driver controls the reduction motor to stop, and the lifting mechanism stops rising. The lifting mechanism waits for the next grab task.

[0194] 9. The dosing work is completed.

[0195] Get medicine:

[0196] 1. After the control panel receives the medicine picking instruction issued by the superior system, the control panel driver controls the metering and pushing device to start metering, the control panel driver controls the discharge and medicine taking device to start action, and the control panel driver controls the shearing mechanism to start working.

[0197] 2. The reduction motor in the lower discharging and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt bring out the medicinal materials.

[0198] 3. As the medicinal pieces are taken out, the height of the medicinal pieces in the hopper drops, and the pressure plate mechanism with a counterweight also drops under the action of its own weight, maintaining continuous pressure on the medicinal pieces. At the same time, the pressure plate mechanism drives the sealing steel belt to rotate forward to ensure the sealing of the hopper.

[0199] 4. One-time medicine-taking and shearing process: after the composite conveyor belt rotates continuously for a specified time, the reduction motor in the discharging and medicine-taking device under the control of the control board driver stops working; at the same time, the control board driver controls the shear reduction motor in the shearing mechanism to move, and the short-edged toothed blade starts to rotate at high speed; at the same time, the control board driver controls the gear reduction motor in the shearing mechanism to move, and the active gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the top plate of the movable pressure block downward, and the top plate of the movable pressure block drives the movable pressure block to move downward, and the movable pressure block presses the medicinal material slices in the discharge port, and under the action of the cam, long spring and short spring behind the driven wheel, the medicinal material slices are kept in a compressed state for a period of time during the rotation of the driven wheel; in the process of the medicinal material slices being compressed, the active gear drives the driven wheel to rotate, and at the same time, the shear reduction motor and the short-edged toothed blade are driven to move back and forth on the slide rail through the connecting rod, and the short-edged toothed blade cuts the medicinal material slices, and the medicinal material slices fall into the weighing pan of the metering, pushing and flipping device. At this point, the medicine cutting work is completed.

[0200] 5. After repeated medicine picking and cutting operations, the medicine reaches the required weight, the metering and pushing device stops measuring, the lower discharging and medicine picking device stops moving, and the shearing mechanism resets and stops working. Wait for the medicine to be discharged.

[0201] Dispensing medicine:

[0202] 1. After the control board receives the medicine dispensing instruction from the superior system, the control board driver 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 sealing plate of the rear door and drives the lower sealing 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.

[0203] 2. The control panel driver controls the action of the back door device while controlling the action 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 back door. After moving horizontally for a certain distance, the gear and rack on the scale plate engage, so that the scale plate has a flipping movement on the basis of horizontal movement, and starts 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.

[0204] 3. After the scale pan maintains the tilting angle for a certain period of time, the control board driver controls the motor in the metering push flip 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.

[0205] 4. When the metering push flip device is reset, the control board driver 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 sealing plate and the lower sealing plate 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 a closed state.

[0206] 5. Wait for the next dose of medicine.

9. A metrology calibration method for a metrology calibration device according to any one of claims 1 to 7, characterized in that: The following steps are involved: (1) The control system issues a "measurement correction" command; (2) The unit medicine cabinet control panel controls the metering push flip device to reset the scale to zero; (3) The unit medicine cabinet control panel controls the operation of the motor of the metering calibration device, driving the winding rod of the mainspring wire and the winding device of the weight wire to rotate; (4) The weight line reel releases the weight line and gently puts the weight down. At the same time, the weight releases the reset touch switch, and the unit medicine cabinet control panel detects that the weight has moved; (5) As the weight moves, the winding rod reels in the winding wire, pulls the winding wire out of the winding disc, turns it through the pulley, passes through the small hole at one end of the spring sheet, and winds it into the wire groove in the winding rod; (6) The weight continues to drop until it falls into the scale pan of the metering push-turn device. The weight is no longer subject to any pulling force. The motor continues to work for a certain period of time and then stops. The weight line winder continues to rotate for a certain period of time to release more weight line, leaving the extra weight line hanging in the air so that it does not affect the accuracy of the weight. The length of "the motor continues to work for a certain period of time" is controlled by the positioning node on the clockwork line and needs to be set in advance. (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning node fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning node is larger than the small hole of the spring sheet, the mainspring continues to be retracted, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control board detects that the weight has reached the predetermined position and controls the motor to stop rotating; (8) When the weight of the specified weight of the metering calibration device falls into the scale pan of the metering push flip device, the metering device of the metering push flip device will read the metering data of the weight in the current scale pan and send it to the unit medicine cabinet control board. The unit medicine cabinet control board compares the metering data with the weight data of the weight entered in advance. If the comparison error is within the specified error range, the metering device of the metering push flip device is determined to be qualified. If the comparison error exceeds the specified error range, the metering device of the metering push flip device is unqualified, and the unit medicine cabinet control board alarms the superior system, prompting that the metering device in the metering push flip device needs to be replaced; (9) The control system controls the metering push device to automatically control the motor to rotate in the opposite direction after the metering calibration is completed. The weight line winder reels in the weight line to lift the weight, and the winding line rod releases the winding line. The winding line is pulled by the spring and wound into the spring disk. The positioning node goes back with the spring line, and the spring sheet rebounds to release the weight in place to touch the switch. The control system detects that the weight starts to return; (10) The weight continues to rise and enters the weight reset fixing seat. The weight is fixed and the paddle of the weight reset touch switch is pressed. The system detects that the weight reaches the initial fixed position and controls the motor to stop rotating. (11) Metrology calibration is completed.

10. A method for controlling a control panel of a unit medicine cabinet according to any one of claims 1 to 8, characterized in that: The following steps are involved: Dosing:

1. The control panel receives the instruction from the upper system to unlock the dosing door.

2. The control board driver controls the reduction motor in the lifting mechanism to rotate, and drives the screw rod to rotate through the gear, and the screw rod pushes the grab plate fixed on the screw rod nut to move downward; when the grab plate moves downward to pass through the grab plate fixing tower cap (i.e., the round table 707), it touches the lifting limit switch, and the control board driver controls the reduction motor to stop rotating, and the grab plate stops moving downward. At this time, the grab plate nail pops out under the action of the grab plate spring and jams the grab plate fixing tower cap, so that the grabbing action of the grab plate is completed; 3. When the grabbing plate completes the grabbing action, the control panel driver controls the reduction motor in the lifting mechanism to immediately start to rotate in the reverse direction, the grabbing plate moves upward, and at the same time drives the pressing plate mechanism to move upward together, and drives the sealing steel belt to rotate in the reverse direction to ensure the sealing of the hopper; 4. When the pressing plate mechanism is lifted to the top of the hopper, the hinge pressing plate in the pressing plate mechanism enters the hinge folding frame, and the hinge pressing plate is folded. At this time, the grab plate touches the limit switch of the lifting mechanism, and the control board driver controls the reduction motor to stop, and the lifting mechanism and the pressing plate mechanism stop rising; 5. The control panel driver 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; 6. The user loads the medicinal pieces into the hopper; 7. The user manually closes the dosing door; 8. The reduction motor of the lifting mechanism rotates, the grab plate moves downward, and the pressing plate mechanism moves downward under the action of its own weight and the grab plate. The hinge pressing plate exits the hinge folding frame, and the hinge baffle is unfolded into a 180° flat plate under the action of the torsion spring. As the grab plate and the pressing plate mechanism continue to move downward, the hinge pressing plate contacts the top of the medicinal material slices in the hopper until the full weight of the pressing plate mechanism presses the medicinal material slices, and the pressing plate mechanism will not move downward at this time; 9. After the pressure plate mechanism stops moving, the lifting mechanism continues to move downward, and the grab plate moves downward with the lifting mechanism through the grab plate movable tower cap, i.e., the inverted round table 708. After the grab plate passes through the grab plate movable tower cap, it touches the lowering limit switch, and the reduction motor starts to rotate in the opposite direction. The lifting mechanism starts to move upward, and the grab plate moves upward with the lifting mechanism through the grab plate movable tower cap and the grab plate fixed tower cap, so that the lifting mechanism grab plate is separated from the pressure plate mechanism, and the release action of the grab plate is completed; the lifting mechanism continues to move upward, and the grab plate touches the lifting mechanism limit switch, and the control board driver controls the reduction motor to stop, and the lifting mechanism stops rising; the lifting mechanism waits for the next grab task; 10. The dosing work is completed; Get medicine:

1. After the control panel receives the medicine picking instruction from the superior system, the control panel driver controls the metering and pushing device to start metering, the control panel driver controls the discharge and medicine taking device to start action, and the control panel driver controls the shearing mechanism to start working; 2. The reduction motor in the lower discharging and medicine taking device drives the composite conveyor belt to rotate, and the steel nails on the composite conveyor belt take out the medicinal materials; 3. As the medicinal pieces are taken out, the height of the medicinal pieces in the hopper drops, and the pressure plate mechanism with a counterweight also drops under the action of its own weight, maintaining continuous pressure on the medicinal pieces; at the same time, the pressure plate mechanism drives the sealing steel belt to rotate forward to ensure the sealing of the hopper; 4. One-time medicine-taking and shearing process: After the composite conveyor belt rotates continuously for a specified time, the control panel driver controls the reduction motor in the material-taking and medicine-taking device to stop working; at the same time, the control panel driver controls the shear reduction motor in the shearing mechanism to move, and the short-edged toothed blade starts to rotate at high speed; at the same time, the control panel driver controls the gear reduction motor in the shearing mechanism to move, and the active gear drives the driven gear and the cam behind the driven gear to rotate together. During the rotation of the driven gear, the cam behind the driven gear presses the top plate of the movable pressing block downward. The upper top plate of the movable pressing block drives the movable pressing block to move downward, and the movable pressing block presses the medicinal material slices in the discharge port, and under the action of the cam, long spring and short spring behind the driven wheel, the medicinal material slices are kept in a pressed state for a period of time during the rotation of the driven wheel; while the medicinal material slices are pressed, the driving gear drives the driven wheel to rotate, and the shearing reduction motor and the short-edged toothed blade are driven to move back and forth on the slide rail through the connecting rod, and the short-edged toothed blade cuts the medicinal material slices, and the medicinal material slices fall into the weighing pan of the metering, pushing and flipping device; at this point, a medicine picking and shearing work is completed; 5. After repeated medicine taking and shearing, the medicine reaches the required weight, the metering and pushing device stops measuring, the lower discharging and medicine taking device stops moving, and the shearing mechanism resets and stops working; wait for the medicine to be taken out; Dispensing medicine:

1. After the control panel receives the medicine dispensing instruction from the upper system, the control panel driver 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 sealing plate of the rear door and drives the lower sealing 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; 2. The control board driver controls the action of the back door device while controlling the action of the metering push flip device. The motor in the metering push flip device starts to rotate, pushing the scale plate to move toward the back door. After moving horizontally for a certain distance, the gear on the scale plate engages with the rack, so that the scale plate has a flipping motion on the basis of horizontal movement, and starts 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 keeps the tilting angle for a certain period of time, the control board driver controls the motor in the metering push flip device to start reverse rotation, 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; 4. When the metering push flip device is reset, the control board driver 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 sealing plate and the lower sealing plate 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 a closed state; 5. Wait for the next dose of medicine.
