[0025] Compared with the prior art, the present invention has the following technical features and advantages:

[0026] 1. Independence: One unit medicine cabinet is an independent individual, and as long as the external power supply and communication network are connected, it can independently complete the functions of adding medicine, taking medicine, and discharging medicine.

[0027] 2. One-key connection mode: The wire groove on the cabinet is a reserved channel for connecting the power supply line and communication line outside the cabinet for the unit medicine cabinet. Through the plug-in type wiring terminal in the wire groove, the one-key connection mode of power-on communication for the unit medicine cabinet can be realized.

[0028] 3. Adaptability: By adopting different hoppers, lower discharge medicine taking devices, and different weight counterweights, it can adapt to the changes in the shape and bulk density of medicinal herb slices and complete the medicine taking work of different medicinal herb slices.

[0029] 4. Modularity: Various devices in the unit medicine cabinet, such as lower discharge medicine taking devices, metering pushing and flipping, metering correction devices, rear door devices, adding medicine doors, cabinet front doors, etc., all adopt modular design and have relatively independent functions. If a certain device fails, it can be replaced separately, thereby achieving rapid replacement and repair. In particular, the card strip of the lower discharge medicine taking device is matched with the card slot on the hopper, and the design method of positioning and fixing the two components by using locking screws and locking holes realizes the rapid installation, disassembly, and positioning of the lower discharge medicine taking device.

[0030] 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.

[0031] 6. Accurate dispensing: The lower dispensing and dispensing device utilizes a specially designed composite conveyor belt. Through the careful design of the width, height, and size of the steel teeth, the planing mechanism and elastic briquetting mechanism separate the difficult-to-separate medicinal pieces and allow them to fall smoothly onto the weighing pan, achieving accurate dispensing. The elastic briquetting mechanism can be adjusted up and down according to the number of medicinal pieces at the outlet, effectively compacting the pieces.

[0032] 7. Fast medicine dispensing speed: The entire medicine dispensing and planing device seems complicated, but it works closely with high speed and efficiency, and can meet the purpose of quickly picking up medicinal materials.

[0033] 8. Eliminate the phenomenon of material bridge: Under the action of its own weight and the counterweight block, the pressing plate mechanism 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 of medicinal slice materials.

[0034] 9. Self-cleaning capability: A cleaning scraper is designed inside the lower discharge and drug removal 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 13. Prevent medicine scattering during medicine addition: There are side baffles for the feeding door on both the left and right sides of the medicine addition door to prevent the medicinal herb slices from accidentally falling outside the hopper during the medicine addition process. The side baffle of the medicine addition door is inserted into the baffle box of the medicine addition door, and a sealing brush strip is arranged inside the side baffle box of the medicine addition door to prevent the medicinal herb slices from accidentally falling into the side baffle box.

[0039] 14. Prevent contamination: The control panel is covered with a control panel box, isolating the connection between the control panel and the internal space of the cabinet, avoiding the contamination of the control panel by the medicine dust inside the cabinet. During the process of taking medicine, more medicine dust may be generated for the medicinal herb slices corresponding to some unit medicine cabinets, causing contamination inside the unit medicine cabinets. To prevent this kind of medicine dust contamination, a dust-proof isolation board (or dust-proof isolation mesh cloth) can be set to divide the internal part of the cabinet into two areas. The upper part is the heat dissipation area, and the lower part is the medicine output area, reducing the space contaminated by medicine dust. The two areas are isolated from each other and do not affect each other. The medicine dust generated in the medicine output area with larger medicine dust will not contaminate the heat dissipation area, and the medicine output area is regularly cleaned during use.

[0040] 15. Manual unlocking available: Both the electric control locks of the front cabinet door and the medicine addition door are designed with manual mechanical unlocking parts, and the front cabinet door and the medicine addition door can be opened manually through artificial means in case of the failure of the electric control locks.

[0041] 16. Regularly calibrate the metering error: A metering calibration device is installed above the metering pushing and flipping device corresponding to the unit medicine cabinet. The upper-level system can regularly drive the metering calibration device through the control panel driving program of the unit medicine cabinet to calibrate the metering accuracy of the metering pushing and flipping device, so as to ensure the metering accuracy of the metering pushing and flipping device.

[0042] 17. Sealing of the hopper: When the pressing plate mechanism moves up and down, the sealing steel belt moves up and down together with the pressing plate mechanism, and the steel belt pressing plate always presses the sealing steel belt, so that the sealing steel belt covers the strip-shaped groove of the hopper, achieving the effect of sealing the hopper.

[0043] 18. Adapt to the type of medicinal herbs: The composite conveyor belt type lower discharge belt planing unit medicine cabinet is suitable for this type of medicinal herb slices with light quality, easy to form clusters among the medicinal herb slices, and certain entanglement between single grains of the medicinal herb slices, such as chrysanthemum, inula flower, etc. Brief Description of the Drawings

[0089] The metering and calibration method of the metering and calibration device includes the following steps:

[0090] (1) The control system issues a "metering and calibration" command;

[0091] (2) The control board of the unit medicine cabinet controls the metering and pushing and flipping device to zero the weighing of the weighing pan;

[0092] (3) The control board of the unit medicine cabinet controls the motor of the metering and calibration device to work, driving the winding rod of the clockwork wire and the weight wire winder to rotate;

[0093] (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;

[0094] (5) As the weights move, the winding rod reels in the winding wire, pulling the winding wire out of the winding disc, turning it through the pulley, passing through the small hole at one end of the spring sheet, and winding it into the wire groove in the winding rod;

[0095] (6) The weight continues to drop until it falls into the scale pan of the metering push-turn device. The weight is no longer subjected to any tension. 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.

[0096] (7) After the weight falls onto the scale plate of the metering push-turn device, the positioning section fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning section is larger than the small hole of the spring sheet, the mainspring is further wound up, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control panel detects that the weight has reached the predetermined position and controls the motor to stop rotating.

[0097] (8) When the weight of the specified weight of the metering calibration device falls into the scale pan of the metering push-turning device, the meter of the metering push-turning 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 meter of the metering push-turning device is judged to be qualified. If the comparison error exceeds the specified error range, the meter of the metering push-turning device is unqualified. The unit medicine cabinet control board alarms the superior system, prompting that the meter in the metering push-turning device needs to be replaced;

[0098] (9) After the control system controls the metering push device to automatically measure and calibrate, it controls the motor to rotate in the opposite direction. The weight line winder reels in the weight line, lifts the weight, and the winding rod releases the line. The line is pulled by the spring and wound into the spring disk. The positioning node goes back with the line, and the spring sheet rebounds to release the weight into place and touches the switch. The control system detects the weight and starts to return.

[0099] (10) The weight continues to rise and enters the weight reset fixed 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.

[0100] (11) Metrological calibration is completed.

[0101] The control method of the control panel of the unit medicine cabinet is characterized by comprising the following steps:

[0102] Drug addition:

[0103] 1. When the control board receives the unlocking instruction for the drug addition door sent by the superior system, the control board controls the electric lock of the drug addition door to be powered on and unlocked. The drug addition door automatically pops up and opens under the action of the spring piece and remains in the open state.

[0104] 2. The user loads the medicinal herb slices into the hopper.

[0105] 3. The user manually closes the drug addition door, and the drug addition is completed.

[0106] Drug retrieval:

[0107] After the control board receives the drug retrieval instruction sent by the superior system, the control board controls the stirring device to start stirring, the control board controls the metering and pushing device to start metering, and the control board controls the upper discharge and drug retrieval device to start operating; the motor in the upper discharge and drug retrieval device drives the composite conveyor belt to rotate. The baffle on the composite conveyor belt takes out the medicinal herb slices from the hopper like a spoon, passes through the limit spring piece and the inner material cover, and under the action of the limit spring piece and the inner material cover, the excess medicinal herb slices are blocked in the hopper, so that the baffle generally only takes out one or one piece of medicinal herb slices, thus meeting the requirement of accurate metering; the medicinal herb slices fall into the weighing pan in the metering and pushing and flipping device through the discharge cover until the weight of the medicinal herb slices in the weighing pan in the weighing pan is greater than or equal to the rough drug retrieval metering set value, the upper discharge and drug retrieval device starts to pick up drugs point by point, until the required weight is reached, the metering and pushing device stops metering, the upper discharge and drug retrieval device stops operating, and the stirring device stops stirring.

[0108] Drug discharge:

[0109] 1. After the control system receives the drug discharge instruction sent by the superior system, the control board controls the motor in the rear door device to rotate outwards, and drives the connecting rod and the sensor dial to rotate outwards. The connecting rod jacks up 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, and the motor stops rotating, and the rear door device remains in the open state.

[0110] 2. While the control board controls the rear door device to operate, it controls the metering and pushing and flipping device to operate. The motor in the metering and pushing and flipping device starts to rotate, pushing the weighing pan towards the rear door. After moving horizontally for a certain distance, the gear on the weighing pan turntable meshes with the rack, so that the weighing pan has a flipping motion on the basis of horizontal movement and starts to pour out the medicinal herb slices. Until the weighing pan flips to a certain angle and touches the limit switch, the motor stops rotating and the weighing pan stops flipping. At this time, the medicinal herb slices can be completely poured out.

[0111] 3. After the weighing pan maintains a certain tilting angle for a certain period of time, the control board controls the motor in the metering pushing and flipping device to start rotating in the reverse direction. The weighing pan rotates back to the horizontal state, then moves horizontally and retracts. After touching the limit switch, the motor stops rotating and the weighing pan resets.

[0112] 4. After the metering pushing and flipping device resets, the control board 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, and the motor stops rotating. The rear door device is in the closed state.

[0113] 5. Wait for the next medicine delivery.

9. A metrology calibration method using the metrology calibration device according to any one of claims 1 to 8, 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 metering calibration device motor, driving the winding rod of the mainspring wire and the weight wire winding device 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 weights move, the winding rod reels in the winding wire, pulling the winding wire out of the winding disc, turning it through the pulley, passing through the small hole at one end of the spring sheet, and winding 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 subjected to any tension. 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 section fixed on the mainspring passes through the pulley and reaches the spring sheet. Since the positioning section is larger than the small hole of the spring sheet, the mainspring is further wound up, which will move the spring sheet. The spring sheet will press the weight into place and touch the switch. The unit medicine cabinet control panel 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-turning device, the meter of the metering push-turning 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 meter of the metering push-turning device is judged to be qualified. If the comparison error exceeds the specified error range, the meter of the metering push-turning device is unqualified. The unit medicine cabinet control board alarms the superior system, prompting that the meter in the metering push-turning device needs to be replaced; (9) After the control system controls the metering push device to automatically measure and calibrate, it controls the motor to rotate in the opposite direction. The weight line winder reels in the weight line, lifts the weight, and the winding rod releases the line. The line is pulled by the spring and wound into the spring disk. The positioning node goes back with the line, and the spring sheet rebounds to release the weight into place and touches the switch. The control system detects the weight and starts to return. (10) The weight continues to rise and enters the weight reset fixed 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) Metrological 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 unlocking instruction of the dosing door from the upper system, and 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 in the open state; (2) The user loads the medicinal pieces 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 metering pushing device to start metering, and controls the upper discharging and medicine taking device to start action; the motor in the upper discharging and medicine taking device drives the composite conveyor belt to rotate, and the baffle on the composite conveyor belt takes the medicinal material slices out of the hopper like a spoon, passes through the limiting spring piece and the inner material cover, and the excess medicinal material slices are blocked in the hopper under the action of the limiting spring piece and the inner material cover, so that the baffle generally only takes out one or one medicinal material slice, thereby achieving the requirement of accurate measurement; the medicinal material slices pass through the discharge cover and fall into the weighing pan in the metering pushing and flipping device, until the weight of the medicinal material slices in the medicine pan on the weighing pan is greater than or equal to the rough medicine measurement setting value, the upper discharging and medicine taking device starts to jog and take medicine, until the required weight is reached, the metering pushing device stops metering, 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 instruction from the upper 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; (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 a certain distance of horizontal movement, the gear on the scale plate engages with the rack, so that the scale plate can flip on the basis of horizontal movement and start 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. 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 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.
