For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural diagram of an embodiment of a device for detecting the object in position according to the present disclosure. The dispenser in-position detection device includes at least two ranging sensors and a controller. As shown in fig. 1, only the first ranging sensor 11, the second ranging sensor 12, and the controller 13 are shown in this embodiment.

As shown in fig. 2 and 3, the first distance measuring sensor 11 and the second distance measuring sensor 12 are located on the end surface of the protruding part 21 of the robot facing the dispensing object. The robot comprises a protruding part 21 and a chassis 22, the protruding part 21 being arranged on the chassis 22. In some embodiments, the end surface of the protruding part 21 facing the dispensing object is arranged perpendicular to the bottom plate 22. The protruding member 21 may be provided at the front end or the rear end of the chassis 22 in the running direction. The raised member 21 may be a nose raised relative to the chassis.

In some embodiments, the dispenser is, for example, a dispensing cart. The dispensing vehicle may be provided with legs and running means, such as universal wheels.

In some embodiments, the projection of the first ranging sensor 11 on the chassis 22 is not coincident with the projection of the second ranging sensor 12 on the chassis 22.

In some embodiments, the distance between the projection of the first ranging sensor 11 on the chassis 22 and the projection of the second ranging sensor 12 on the chassis 22 is greater than or equal to a distance threshold. For example, the first distance measuring sensor 11 and the second distance measuring sensor 12 are respectively positioned at the left side and the right side of the end surface of the convex part 21 of the robot facing the objects to be dispensed, so that the relative distance and angle between the objects to be dispensed and the convex part can be monitored in real time, and the objects to be dispensed and the convex part can be ensured to be parallel.

The first and second distance measuring sensors 11 and 12 are configured to detect distance information between the projection member 21 and the end surface of the dispensing object facing the at least two distance measuring sensors, and to transmit the detected distance information to the controller 13. For example, the first distance measuring sensor 11 transmits the detected first distance information to the controller 13, and the second distance sensor 12 transmits the detected second distance information to the controller 13.

In some embodiments, the first and second distance measuring sensors 11 and 12 are infrared distance measuring sensors, for example. For example, the measurable range of the infrared distance measuring sensor is 1-100 cm, and when a shelter exists on the front surface, the infrared distance measuring sensor can output distance information from the shelter to the sensor. When the distribution vehicle enters the robot, the distance measured by the infrared distance measuring sensor is gradually reduced along with the distance of the distribution vehicle relative to the entering distance.

In some embodiments, as shown in fig. 4, the first distance sensor 11 outputs the detected first distance information as an analog voltage amount, the driving capability of the output analog voltage amount is increased by the first voltage follower 41, the voltage signal output by the first voltage follower 41 is input to the first operational amplifier 42, and the first operational amplifier 42 amplifies the analog amount carrying the first distance information and inputs the amplified analog amount to the first analog-to-digital converter 43. The first distance measuring sensor 12 outputs the detected second distance information as an analog voltage amount, the driving capability of the output analog voltage amount is increased by the second voltage follower 44, the voltage signal output by the second voltage follower 44 is input to the second operational amplifier 45, and the second operational amplifier 45 amplifies the analog amount carrying the second distance information and inputs the amplified analog amount to the first analog-to-digital converter 43. The first analog-to-digital converter 43 converts an analog quantity into a digital quantity, and inputs the digital quantity to the controller 13 through a Serial Peripheral Interface (SPI).

The controller 13 is configured to determine whether the dispensing item is already located at a predetermined position of the chassis 22 of the robot, based on the distance information.

For example, if it is determined that the first distance information detected by the first distance measuring sensor 11 is equal to or less than the distance threshold value and the second distance information detected by the second distance measuring sensor 12 is equal to or less than the distance threshold value, it is determined that the dispensing object is located at the predetermined position of the chassis 22.

For example, when the distance information detected by the first distance measuring sensor 11 and the second distance measuring sensor 12 is less than 4cm, it indicates that the dispensing object is located at the predetermined position of the chassis 22. If the distance detected by the first distance measuring sensor 11 is 10cm and the distance detected by the second distance measuring sensor 12 is 4cm, it indicates that the objects to be dispensed are inclined or have other interference, and the adjustment should be performed in time so that the objects to be dispensed reach the predetermined position of the chassis 22.

In some embodiments, if the load is already at a predetermined position on the chassis 22 of the robot, the controller 13 sends a command to the jacking mechanism 23 to lift the load. For example, the controller 13 sends a command to the motor driver 231 of the lift mechanism 23 to control the lift motor 232 to move, so that the push rod 233 of the lift mechanism is pushed upwards to lift the dispensing object off the ground.

In the above embodiment, at least two distance measuring sensors are provided on the end surface of the protruding part of the robot facing the dispensing object to detect the distance information between the protruding part and the end surface of the dispensing object facing the at least two distance measuring sensors, and it is determined whether the dispensing object is located at a predetermined position on the chassis of the robot based on the distance information. The precision of whether the detection distribution object is located at the preset position of the robot can be improved, and the loss in the transportation process is reduced.

In another embodiment of the present disclosure, in the process of transporting and delivering the objects according to the preset path, the first distance measuring sensor 11 and the second distance measuring sensor 12 respectively send the detected first distance information and second distance information to the controller 13 in real time, when the first distance information changes or the second distance information changes, it indicates that the objects to be delivered have a shaking risk or a falling risk, and the controller 13 sends out an alarm signal in time, so that loss caused by falling of the objects to be delivered can be avoided.

In other embodiments of the present disclosure, the device for detecting the article in position further includes a pressure sensor 14 disposed on the jacking mechanism 23 and configured to send information about the detected pressure applied to the jacking mechanism 23 to the controller 13; the controller 13 is further configured to send an instruction to the jacking mechanism 23 to stop lifting the dispense when it is determined that the pressure information is greater than the pressure threshold.

For example, in the process of lifting the jacking mechanism 23, the pressure sensor 14 located on the jacking mechanism 23 outputs the pressure borne by the jacking mechanism in the form of an analog voltage quantity, the analog voltage quantity is input to the controller 13 through the third operational amplifier 46 and the second analog-to-digital converter 47, the controller 13 calculates the pressure borne by the jacking mechanism, and when the delivered object is overweight, the controller 13 sends a command to the motor driver 231 of the jacking mechanism 23 to control the jacking motor 232 to stop running and give an alarm to the upper computer.

In the embodiment, when the delivered objects are overweight, the jacking mechanism stops moving, overload and cargo loading can be prevented, and the probability of danger in the transportation process is reduced.

In other embodiments of the present disclosure, the dispenser-in-place detecting device further includes: a first height detection sensor 15 configured to send a first signal to the controller 13 when the lifting mechanism 23 is detected to be lifted to a predetermined height; the controller 13 is further configured to send an instruction to the jacking mechanism 23 to stop lifting the allocation upon receiving the first signal. For example, when the dispensed objects are in the load-bearing range of the robot and the robot lifts the dispensed objects gradually, the first height detection sensor 15 installed in the jacking mechanism is triggered to send a switching value signal at a certain moment, the controller 13 inputs the switching value signal to the controller 13 after being compared by the first comparator 48, and the controller 13 sends a command to the motor driver 231 to control the jacking motor 232 to stop running after knowing that the push rod 233 is lifted to the preset position.

In other embodiments, the delivery arrival detection apparatus further comprises: a second height detection sensor 16 configured to send a second signal to the controller 13 upon detecting that the jacking mechanism 23 is lowered to the initial position; the controller 13 is further configured to send an instruction to stop the lowering to the jacking mechanism 23 upon receiving the second signal. For example, after the robot reaches the destination, the controller 13 sends a command to the motor driver 231 to control the operation of the jacking motor 232 so as to lower the push rod 233, and when the push rod 233 triggers the output signal of the second height detection sensor 16 at the initial position, the signal is compared by the second comparator 49 and then input to the controller 13, and the controller 13 knows that the push rod 233 has been lowered to the initial position, and sends a command to the motor driver 231 to control the jacking motor 232 to stop operating.

In some embodiments, the first height detection sensor 15 and the second height detection sensor 16 are infrared pair tubes. The infrared pair transistors comprise light emitting diodes and photosensitive diodes, and when a shelter is arranged between the light emitting diodes and the photosensitive diodes, measurement data can be output. For example, a baffle plate is arranged on the push rod, the infrared pair transistors are arranged on two sides of the baffle plate, and when the baffle plate moves to the position of the infrared pair transistors, the infrared pair transistors can output measurement data.

In the above-described embodiment, by providing the first height detection sensor and the second height detection sensor, it is possible to prevent the jacking mechanism from being lifted up too high and lowered down too much.

In another embodiment of the disclosure, a robot is protected, which comprises the above-mentioned object position detection device.

In another embodiment of the present disclosure, a dispensing device is protected, the dispensing device comprising the robot and a dispensing object as described above, wherein the dispensing object is provided separately from the robot. In some embodiments, the dispenser is a dispensing vehicle.

The distribution device is applied to places such as hospitals, the robot carries the distribution vehicle, the position of the distribution vehicle can be detected, the distribution vehicle is ensured to be located at the proper position of the robot, in addition, the state of the distribution vehicle is monitored in real time in the transportation process, the timely alarm is ensured when the distribution vehicle encounters the falling risk, and the loss is reduced.

Fig. 5 is a schematic flow chart of an embodiment of a method for detecting the presence of a dispensed product according to the present disclosure.

In step 510, the controller receives distance information detected by at least two distance measuring sensors, wherein the at least two distance measuring sensors are disposed on an end surface of the protruding part of the robot facing the dispensing object, and each of the at least two distance measuring sensors detects distance information of the protruding part and the end surface of the dispensing object facing the at least two distance measuring sensors.

In step 520, the controller determines whether the dispensing item is already located at a predetermined position of the chassis of the robot based on the distance information.

In this embodiment, on the end surface of the protruding part of the robot facing the dispensing object, at least two distance measuring sensors are provided to detect distance information of the protruding part from the end surface of the dispensing object facing the at least two distance measuring sensors, and based on the distance information, it is determined whether the dispensing object has been located at a predetermined position on the chassis of the robot. The precision of whether the detection distribution object is located at the preset position of the robot can be improved, and the loss in the transportation process is reduced.

As shown in fig. 6, the present embodiment will be described below by taking a one-time delivery vehicle as an example.

At step 610, the first ranging sensor transmits the detected first distance information to the controller, and the second ranging sensor transmits the detected second distance information to the controller.

In step 620, the controller determines whether the first distance information and the second distance information are both less than or equal to the distance threshold, if so, step 630 is executed, otherwise, step 631 is executed.

At step 630, the controller sends a command to the jacking mechanism to lift the delivery vehicle. At this time, it is described that the dispensing car is located at a predetermined position on the chassis of the robot.

At step 631, the position of the delivery vehicle is adjusted.

In step 640, the controller receives pressure information detected by the pressure sensor.

In step 650, the controller determines whether the pressure information is greater than the pressure threshold, and if so, performs step 660, otherwise, performs step 670.

At step 660, the controller sends an instruction to the jacking mechanism to stop lifting the distribution.

In step 670, the controller sends an instruction to the jacking mechanism to stop lifting the delivered object when receiving the first signal sent by the first height detection sensor; the first height detection sensor sends a first signal to the controller when detecting that the jacking mechanism is lifted to a preset height.

At step 680, the controller sends an operating instruction to the robot. The robot transports the delivery vehicle according to a preset path.

In step 690, the controller determines whether the first distance information or the second distance information changes in real time, if so, then step 6100 is performed, otherwise, step 690 is continued.

At step 6100, the controller sends an alert to adjust the position of the dispensing vehicle in time.

In step 6110, the controller sends a stop instruction to the robot when detecting that the robot has moved to the designated position.
