Examples

The application provides an intelligent medicine box, as shown in fig. 1 and fig. 2.

The intelligent medicine box comprises a base body 100 and a controller.

The base body 100 is provided with a medicine storage device 200 for storing tablets and a medicine discharge passage 300 for communicating the inside and outside of the base body 100.

The inventor finds that in the existing intelligent medicine box, when a large number of tablets are stacked in the medicine storage part, incomplete tablets are easy to output in the medicine output part, when a small number of tablets are stacked in the medicine storage part, the medicine output part cannot output the tablets, and the medicines can be accurately output only when the stacking height of the tablets is proper, so that the existing intelligent medicine box has a large medicine dispensing error.

The inventor further finds that: the reason why incomplete tablets are easily discharged when a large number of tablets are supplied is that the tablets are easily crushed because the stroke distance of the tablet-taking member is longer than the stacking height of the tablets; the reason why the tablets cannot be delivered when the tablets are reduced is that the tablets cannot be taken because the tablets are contacted by the tablet to be taken.

In order to reduce the dispensing error, a dispensing device 400 is further disposed in the base body 100, the controller is electrically connected to the dispensing device 400, a movable picking and placing mechanism 420 is disposed on the dispensing device 400, and the controller controls the picking and placing mechanism 420 to extend into the storage device 200 so that the actuating end thereof contacts the tablet stacking surface, and thus the actuating end of the picking and placing mechanism 420 picks up the tablets on the tablet stacking surface, thereby ensuring that the picking and placing mechanism 420 can effectively pick up the tablets and preventing the tablets from being crushed.

The lifting stroke of the pick-and-place mechanism 420 is flexibly set to ensure that the execution end of the pick-and-place mechanism 420 can reach the tablet accumulation plane regardless of the height of the tablet accumulation plane. That is, the stroke of the pick-and-place mechanism 420 may be set to be greater than or equal to the distance from the starting height position of the execution end to the bottom of the medicine storage device 200.

The pick-and-place mechanism 420 is provided with a first detecting mechanism 430, as shown in fig. 3, when the executing end of the pick-and-place mechanism 420 is collided, the first detecting mechanism 430 can send out a first displacement signal.

In the using process, the controller firstly controls the picking and placing mechanism 420 to extend into the medicine storage device 200, when the first detection mechanism 430 does not send out the first displacement signal, the picking and placing mechanism 420 continuously descends to ensure that the picking and placing mechanism 420 contacts the tablet stacking surface to pick tablets, and when the first detection mechanism 430 sends out the first displacement signal, the controller controls the picking and placing mechanism 420 to move out of the medicine storage device 200 and release the tablets into the medicine storage channel.

The situation that the first detecting mechanism 430 sends the first displacement signal includes that the executing end of the picking and placing mechanism 420 is collided by the tablet stacking surface, in this situation, the executing end of the picking and placing mechanism 420 picks up the tablets and immediately rises when contacting the tablet stacking surface, and the tablet crushing caused by too large force is effectively prevented because the executing end of the picking and placing mechanism 420 continues to descend.

Thus, the intelligent medicine box that this application provided piles up in storing up medicine device 200 under the condition of tablet, can guarantee to export the tablet in going out medicine passageway 300, and the tablet of output is complete to guarantee to dispense accurately, solve because not going out medicine or the incomplete problem that leads to the error of dispensing of tablet.

Fig. 4 shows an exploded view of the pick-and-place mechanism 420, and fig. 5 shows an internal structure diagram of the pick-and-place mechanism 420, wherein the pick-and-place mechanism 420 comprises a suction tube 421 and a sleeve 422.

One end of the suction tube 421 is used for taking tablets by suction and releasing the tablets by canceling the suction force, and the "one end of the suction tube 421" is the execution terminal, and the sleeve 422 is slidably sleeved on one end of the suction tube 421.

The suction force of the suction pipe 421 may be configured to come from the vacuum pump 500, the vacuum pump 500 is electrically connected to the controller, the controller provides the suction force by controlling the operation of the vacuum pump 500, and releases the tablet by controlling the stop of the vacuum pump 500.

The vacuum pump 500 may be disposed in the base 100 and connected to the other end of the suction pipe 421 through a hose. The vacuum pump 500 may be integrally formed with the suction pipe 421.

After one end of the suction tube 421 enters the medicine storage device 200, the protective sleeve 422 contacts the tablet stacking surface, and then the suction tube 421 continues to descend and extend out of the protective sleeve 422 to contact the tablet stacking surface. The first detection mechanism 430 signals a first displacement when the pipette 421 is extended out of the protective sleeve 422.

The first detection mechanism 430 includes a first sensor 431 and a first trigger structure 432, the first sensor 431 being disposed on the straw 421 and the first trigger structure 432 being disposed on the sleeve 422. When the protective sleeve 422 touches the tablet stacking surface and stops descending, but the straw 421 continues to descend, the first sensor 431 is triggered near the first trigger structure 432, thereby emitting a first displacement signal.

The first sensor 431 may be configured as a photoelectric switch, a grating, or other triggering device type, and the first triggering structure 432 may be configured as a structure corresponding to the triggering device type.

In this embodiment, the first sensor 431 is a ring grating, and the first trigger mechanism is an iron sheet disposed inside the sleeve 422.

The iron plate can also trigger the ring grating when the sleeve 422 rotates circumferentially relative to the generation straw 421 to ensure that the first displacement signal can be effectively emitted.

In some embodiments, the first sensor 431 and the first trigger structure 432 are interchanged in position, i.e., the first sensor 431 is disposed on the sleeve 422 and the first trigger structure 432 is disposed on the straw 421.

In some embodiments, the pick and place mechanism 420 further comprises a resilient member 423, wherein the resilient member 423 is supported between the sleeve 422 and the straw 421 to ensure that the sleeve 422 shields the end of the straw 421 when not being interfered with, thereby further ensuring that the sleeve 422 is interfered with before the end of the straw 421 is interfered with, especially when the straw 421 is configured to enter and exit the drug storage mechanism in other directions (non-vertical directions).

The phrase "the sleeve 422 shields one end of the suction pipe 421" herein means that an end surface of one end of the suction pipe 421 is flush with a lower end surface of the sleeve 422, or that one end of the suction pipe 421 is positioned inside the sleeve 422 so that the end surface of one end of the suction pipe 421 is recessed with respect to the lower end surface of the sleeve 422.

As shown in fig. 5, a tube 421a having a small diameter is formed at one end of the suction tube 421, and a flat surface is formed near the outer periphery of the tube 421 a. That is, the actuating tip of the pipette 421 is reduced.

The interior of the sleeve 422 forms a receiving surface, and the elastic member 423 is supported between the plane of the suction pipe 421 and the receiving surface of the sleeve 422.

In some embodiments, the elastic member 423 is configured as a spring, and the spring is sleeved on the tube 421a and both ends thereof are abutted between the flat surface and the receiving surface.

In some embodiments, the elastic member 423 may be further configured as an elastic piece fixed on one of the plane and the receiving surface and abutted against the other of the plane and the receiving surface.

In some embodiments, the opening of the lower end surface of the sleeve 422 is configured to have an inner diameter matching the outer diameter of the tube 421a, so as to prevent the gap between the sleeve 422 and the tube 421a from catching the extra tablet and prevent the occurrence of over-dispensing errors.

Referring to fig. 5 again, the sleeve 422 comprises a straight cylinder section and a conical section, the straight cylinder section is slidably connected with the straw 421, and the tube 421a can extend out from the opening of the conical section to take tablets.

The tapered section forms an inner cylinder 4221, and the inner cylinder 4221 extends from the opening of the tapered section to the direction of the straight cylinder section so as to be sleeved outside the tube body 421a and play roles of protecting the tube body 421a and guiding.

Alternatively, the aforementioned receiving surface may be formed on the inner cylinder 4221, e.g., formed on the end surface of the inner cylinder 4221 facing the straw 421.

In order to prevent the sleeve 422 from falling off, a first position-limiting portion 4212 is formed on the straw 421, a second position-limiting portion 4222 is formed on the sleeve 422, and the first position-limiting portion 4212 is matched with the second position-limiting portion 4222.

In this embodiment, the first position-limiting portion 4212 is a protrusion formed on the straw 421, the second position-limiting portion 4222 is a strip-shaped groove formed on the sleeve 422, and the protrusion is slidably fitted in the strip-shaped groove.

In some embodiments, the strip-shaped groove is located in the straight barrel section.

The application provides an intelligence medicine box not only can reduce the error of dispensing, can also prevent to get and put the mechanism 420 and store up between the medicine device 200 interact too big and damage. The situation that the first detecting mechanism 430 sends the first displacement signal further includes that the executing end of the pick-and-place mechanism 420 is collided by the bottom of the medicine storage device 200, in this situation, the executing end of the pick-and-place mechanism 420 is immediately raised when the base reaches the bottom of the medicine storage device 200, and the executing end of the pick-and-place mechanism 420 is effectively prevented from being continuously lowered and being damaged.

To further protect the tube 421a, the pick-and-place mechanism 420 further includes a mouthpiece 4211 made of an elastic material. The mouthpiece 4211 is coupled to one end of the straw 421 to provide a buffering effect, further prevent the straw 421 from being damaged, and further prevent tablets from being crushed.

In addition, the suction nozzle 4211 made of elastic material can prolong the action time of the suction pipe 421 and the tablet stacking surface to ensure that the tablets are adsorbed, and reduce the dosage error caused by that the tablets are not adsorbed. The suction nozzle 4211 is compressed by the suction tube 421 being further lowered after the suction nozzle 4211 contacts the tablet, and the suction force of the suction tube 421 is continuously applied to the tablet stacking surface during the compression of the suction nozzle 4211 to ensure the stable absorption of the tablet.

In some embodiments, the nipple 4211 is configured to extend the sleeve 422 such that the nipple 4211 contacts the accumulation surface prior to the sleeve 422. At this time, the distance between the first sensor 431 and the first trigger structure 432 can be reduced, the moving distance of the sleeve 422 can be shortened, and the sensing sensitivity can be improved.

In order to further reduce the error of dispensing, the intelligent medicine box that this application provided still is equipped with load detection mechanism, and load detection mechanism is used for detecting the load of the execution end of pick and place mechanism 420.

The controller is electrically connected to the load detection mechanism, so that after receiving the first displacement signal, the controller determines whether the pick-and-place mechanism 420 has picked up the tablet according to a detection result of the load detection mechanism.

In this embodiment, the load detection mechanism is an air pressure sensor (not shown), and the air pressure sensor is disposed on the suction pipe 421 to detect the air pressure inside the suction pipe 421.

When the first detection mechanism 430 is triggered, if the air pressure is reduced, it indicates that one end of the suction pipe 421 is blocked, and the tablet is successfully taken. At this time, the controller may control the pick-and-place mechanism 420 to go to the medicine discharging passage 300 to discharge the tablets.

When the first detecting mechanism 430 is triggered, the air pressure is first decreased and then increased, which indicates that the tablet taken by one end of the suction tube 421 has fallen and is not successfully taken. At this time, the controller may control the pick-and-place mechanism 420 to descend again to re-adsorb the tablets.

When the first detection mechanism 430 is triggered, the air pressure is not reduced, which indicates that one end of the suction tube 421 is not blocked, and the tablet is not taken. At this point, the controller may issue an alarm signal to prompt the user to add a pill. Thus, the first detection mechanism 430 and the load detection mechanism in combination also function as an empty cartridge detection.

In some embodiments, the load detection mechanism may also be an infrared sensor disposed on the suction pipe 421 to detect whether the tablet is absorbed by the suction pipe 421.

In other embodiments, the load detection mechanism may also be a gravity sensor, a pressure sensor, or the like.

In some embodiments, the smart medicine box further comprises one or more of a display screen 141, a speaker, and a warning light, wherein the display screen 141, the speaker, or the warning light is disposed on the surface of the base 100 for emitting a warning signal. For example, the display screen 141 is electrically connected to the controller, and the controller displays the tablet shortage image signal through the display screen 141. For example, the speaker is electrically connected to the controller, and the controller signals the tablet shortage through the speaker. If the alarm lamp is electrically connected with the controller, the controller displays a lamp light signal indicating that the tablets are insufficient through the alarm lamp.

In order to facilitate the movement of the pick-and-place mechanism 420, the pick-and-place mechanism 400 further includes a sliding base 410, the pick-and-place mechanism 420 is disposed on the sliding base 410 in a liftable manner, the sliding base 410 is movably disposed in the base 100, and the movement of the sliding base 410 drives the pick-and-place mechanism 420 to move, so that the pick-and-place mechanism 420 can be located above the medicine storage device 200 or above the medicine outlet channel 300.

And then the controller controls the horizontal motor 411 to work, the controller judges the position of the sliding seat 410 according to the second displacement signal, when the picking and placing mechanism 420 on the sliding seat 410 corresponds to the upper part of the medicine outlet 133, the controller controls the picking and placing mechanism 420 to release the tablets, and the tablets fall down and pass through the medicine outlet 133 to enter the medicine outlet channel 300.

To increase the types of dispensed medicines, the medicine storage device 200 includes a turntable 210 and a plurality of medicine cartridges 220 disposed on the turntable 210, and each medicine cartridge 220 may store different types of tablets, respectively.

As shown in fig. 8, a plurality of first supporting columns 121 and a plurality of second supporting columns 122 are disposed on the first mounting seat 120.

A plurality of first support columns 121 are arranged around the turntable 210 to define a horizontal position of the turntable 210, preventing the turntable 210 from moving in its own radial direction.

The plurality of second supporting columns 122 are supported at the bottom of the turntable 210, and each second supporting column 122 is provided with a ball 123, so as to reduce the friction force of the turntable 210.

The lower surface of the turntable 210 is provided with a gear ring 211, the first mounting base 120 is provided with a turntable motor 230, and the turntable motor 230 is matched with the gear ring 211 through a gear, so that the turntable 210 is driven to rotate around the axial direction of the turntable 210.

A plurality of cartridges 220 are arranged annularly on the upper surface of the carousel 210 along the circumference of the carousel 210, each cartridge 220 having an upward opening.

The turntable motor 230 drives the turntable 210 to rotate so as to switch the corresponding drug storage bin 220 below the drug taking port 132.

In order to reduce the horizontal moving distance of the pick-and-place mechanism 420, a through hole 212 is formed at the axial position of the turntable 210, the medicine taking port 132 corresponds to the through hole 212, and the medicine outlet channel 300 is a pipe with one end penetrating the through hole 212. Therefore, when taking and releasing the tablets, the taking and releasing mechanism 420 does not need to span the whole turntable 210, so that the intelligent medicine box has a more compact overall structure and a faster dispensing speed.

The structure of the drug storage bin 220 is shown in fig. 9, and comprises a first side wall 221, a second side wall 222 and a bottom wall 223, wherein the first side wall 221 is close to the axial line of the rotary disc 210, the second side wall 222 is far away from the axial line of the rotary disc 210, the first side wall 221 and the second side wall 222 enclose, and the bottom wall 223 is connected to the lower ends of the first side wall 221 and the second side wall 222 so as to be opposite to the opening of the drug storage bin 220.

To prevent the tablets from entering the medicine discharging passage 300 beyond the first sidewall 221, the upper end of the first sidewall 221 extends toward the axis of the rotating disk 210 to form a slope 2211, and the slope 2211 is gradually away from the axis of the rotating disk 210 from the upper end to the lower end. When the tablet stacking surface is high, the inclined surface 2211 serves as a buffer surface to effectively prevent tablets from passing over the first side wall 221, thereby reducing dispensing errors.

Bottom wall 223 of cartridge 220 defines a recess 2231 to allow the tablets to slide toward recess 2231 for accumulation. When the actuating end of the pick-and-place mechanism 420 is located at the drug dispensing opening 132, the horizontal projection of the picking end on the bottom wall 223 of the drug storage bin 220 falls on the concave part 2231. Thereby, the residual tablets in the medicine storage bin 220 are prevented from being taken out.

For convenience of control, the intelligent medicine box further comprises a third detection mechanism 240, the third detection mechanism 240 is used for detecting the rotation angle of the rotating disc 210 and sending a third displacement signal, and the controller judges the position of the target medicine storage bin 220 according to the third displacement signal and controls the rotating disc 210 to rotate, so that the opening of the target medicine storage bin 220 corresponds to the lower part of the medicine taking port 132.

As shown in fig. 10, the third detection mechanism 240 includes a third sensor 241 and a third trigger structure 242.

The third detection mechanism 240 further includes a fourth sensor 243 and a fourth trigger structure 244. The fourth sensor 243 is a grating fixed on the first mounting base 120, and the fourth triggering mechanism 244 is a notched ring disposed on the turntable 210.

After the smart cartridge is not used for a period of time, or before the dispensing of the medicine is started, the turntable 210 may be calibrated first by the fourth sensor 243 and the fourth trigger mechanism 244.

The turntable 210 rotates to enable the fourth sensor 243 to pass through the gap on the gap ring, the fourth sensor 243 sends out a zero-point signal, and the controller determines the zero-point position of the turntable 210 according to the zero-point signal, and specifies the position of each drug storage bin 220 and the position of the target drug storage bin 220 to be taken.
