The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

The following describes a specific structure of the intelligent cabinet according to an embodiment of the present invention with reference to fig. 1 to 7.

As shown in fig. 1 to 7, the intelligent cabinet according to the embodiment of the invention includes a housing 1, a plurality of shelves 2 disposed in the housing 1, a fork mechanism 3 movably disposed in the housing 1, a fork mechanism 3 for inserting and extracting the tray, a driving mechanism 4 connected to the fork mechanism 3, the driving mechanism 4 for driving the fork mechanism 3 to rotate and move along the height direction of the housing 1, and a buffer mechanism 5 for buffering the empty tray and driving it to a position corresponding to the delivery port 11, wherein the fork mechanism 3 is used for placing the empty tray on the buffer mechanism 5 on the shelf 2 and placing the empty tray on the buffer mechanism 5.

It can be understood that in the working process of the intelligent cabinet according to the embodiment of the invention, after the system receives the delivery instruction in the continuous delivery process, the buffer mechanism 5 drives the empty carrying tray to the position corresponding to the delivery port 11, and the goods can fall on the empty carrying tray after the courier drops the goods from the delivery port 11, because the empty carrying tray is from the buffer mechanism 5, but not from the zero position to the goods shelf 2 by the fork mechanism 3, and then is put at the delivery port 11, so that a lot of time can be saved. When the goods are placed on the carrying tray, the automatic door at the delivery opening 11 is closed, the carrying tray loaded with the goods is stored on the goods shelf 2 by the fork mechanism 3 according to the nearby principle, after the goods are stored on the goods shelf 2, the fork mechanism 3 takes an empty carrying tray from the goods shelf 2 specially used for placing the empty carrying tray, the carrying tray is placed on the buffer mechanism 5, and the rear fork mechanism 3 returns to the zero position. Therefore, in this embodiment, after the buffer storage carrying tray on the buffer storage mechanism 5 is used, the fork mechanism 3 brings back an empty carrying tray to be replenished with the used carrying tray after the goods are put, so that the fork mechanism 3 can not be emptied when returning, and only one empty carrying tray is always kept in the buffer storage area, thereby ensuring that the empty carrying tray is always in the buffer storage area when the goods are continuously delivered, and further ensuring the delivery efficiency of the intelligent cabinet.

According to the intelligent cabinet provided by the embodiment of the invention, as the fork mechanism 3 moves the empty carrying tray to the buffer mechanism 5 after goods are placed, the buffer mechanism 5 can drive the empty carrying tray to move to the position corresponding to the delivery opening 11 during delivery, so that the condition that the empty carrying tray exists in the buffer area all the time during continuous delivery of the goods is ensured, and the delivery efficiency of the intelligent cabinet is improved.

In some embodiments, as shown in fig. 6-7, the buffer mechanism 5 includes a pushing module 51 and a separating module 52, the pushing module 51 includes a mounting seat 511, a buffer driving assembly 512 and a bearing member 513, the bearing member 513 is arranged on the mounting seat 511 in a lifting manner, the buffer driving assembly 512 cooperates with the bearing member 513 to drive the bearing member 513 to lift, the separating module 52 includes a separating support 521 and two supporting plates 522, a buffer channel extending along a vertical direction is arranged on the separating support 521, the bearing member 513 is located in the buffer channel, and the two supporting plates 522 are rotatably arranged on two opposite sides of the buffer channel and can jointly support the same carrier tray. Two trays 522 are provided corresponding to the delivery openings 11.

It will be appreciated that in actual operation, after the pallet fork mechanism 3 has placed the load, an empty pallet is placed on the mounting of the push module 51 and the pallet fork mechanism 3 is returned to zero. When the intelligent cabinet sends an inventory instruction, the buffer driving component 512 drives the bearing component 513 to ascend, the object carrying tray is stopped against the supporting plates 522 to ascend continuously and can drive the supporting plates 522 to rotate, and when the object carrying tray exceeds the trays, the buffer driving component 512 drives the bearing component 513 to move downwards, so that the object carrying tray can be supported on the two supporting plates 522. Thereby, it is achieved that the caching mechanism 5 drives the carrier tray to a position corresponding to the delivery opening 11. In this embodiment, the carrier tray is pushed to the separation module 52 by the pushing module 51 so as to move to the position corresponding to the delivery opening 11, and in the delivery process, the time for pushing the carrier tray by the pushing module 51 is very short, so that the delivery efficiency is improved.

It should be noted that, in other embodiments of the present invention, the buffer driving assembly 512 may select any one of a belt structure, a motor-driven ball screw mechanism, an electric push rod, a cylinder, and a hydraulic cylinder according to actual needs.

In some specific embodiments, as shown in fig. 6-7, the separation support 521 includes a support plate 5211, a connection plate 5212, and a rotation shaft 5213, the two support plates 5211 are disposed opposite to each other, a buffer channel is formed between the two support plates 5211, two ends of the connection plate 5212 are respectively connected to the support plates 5211, two ends of the rotation shaft 5213 are connected to the support plates 5211 through a mating base 5214, and the support plate 522 is rotatably connected to the rotation shaft 5213. The stability of the separating support 521 can be ensured, and the motion direction of the carrying tray can be limited by the buffer channel, so that the carrying tray is prevented from being separated from the buffer mechanism 5 under the pushing of the pushing module 51.

In some more specific embodiments, as shown in fig. 6-7, the supporting plate 522 includes two connection portions 5222 and a bearing portion 5221, the two connection portions 5222 are respectively connected to two ends of the bearing portion 5221, and the two connection portions 5222 are all disposed on the rotating shaft 5213 in a penetrating manner, and the bearing portion 5221 is used for bearing the carrying tray. Thereby, on the one hand, a stable support of the pallet 522 to the load tray is ensured, and on the other hand, a rotation of the pallet 522 about the rotation axis 5213 is ensured.

Advantageously, the shaft 5213 is provided with an elastic element for resetting the plate 522. It will be appreciated that during actual movement, after the load tray exceeds the pallet 522, the pallet 522 is reset under its own weight to support the load tray. However, the reliability of this resetting method is poor, and the phenomenon that the pallet 522 cannot be completely reset easily occurs, so that the pallet 522 cannot stably support the carrier tray. In this embodiment, the elastic member is used to forcibly reset the supporting plate 522, so as to ensure the supporting of the supporting plate 522 on the carrying tray, thereby ensuring the reliability of the whole intelligent cabinet.

In some embodiments, as shown in fig. 2, the driving mechanism 4 includes a lifting module 41 and a rotating module 42, the lifting module 41 is connected with the fork mechanism 3, the lifting module 41 is used for driving the fork mechanism 3 to move along the height direction of the shell 1, the rotating module 42 is connected with the lifting module 41, and the rotating module 42 is used for driving the lifting module 41 to rotate. It can be appreciated that by driving the rotating module 42 and the lifting module 41, the fork mechanism 3 can reach any position of the goods shelf 2 in the shell 1, thereby avoiding the dead angle of the intelligent cabinet and improving the utilization rate of the internal space of the shell 1.

The rotating module 42 may be configured by a motor, a rotating cylinder, a rotating mechanical arm, or the like connected to the lifting module 41 according to actual needs, and the specific configuration of the rotating module 42 is not limited herein.

In some alternative embodiments, as shown in fig. 4, the lift module 41 includes a lift frame assembly 411 and a lift driving assembly 412, the lift frame assembly 411 includes a base 4111, a top cover 4112, a rail 4113, and a slider 4114, the base 4111 and the top cover 4112 are disposed at a top-bottom interval, two ends of the rail 4113 are respectively connected to the base 4111 and the top cover 4112, the slider 4114 is slidably disposed on the rail 4113, and the slider 4114 is connected to the fork mechanism 3. The lifting driving assembly 412 comprises two synchronizing wheels 4121, a lifting driving member 4122 and a synchronous belt 4123, wherein the two synchronizing wheels 4121 are arranged at intervals along the length direction of the guide rail 4113 and are respectively connected with the base 4111 and the top cover 4112, the synchronous belt 4123 is matched with the two synchronizing wheels 4121, and the synchronous belt 4123 is connected with the fork mechanism 3.

It can be appreciated that in this embodiment, the fork mechanism 3 is connected to the synchronous belt 4123, and when the lifting driving member 4122 drives the synchronous wheel 4121 to rotate, the fork cabinet can move up and down under the driving of the synchronous belt 4123, so as to realize the lifting of the fork mechanism 3. Since the slider 4114 is connected to the fork mechanism 3 and the slider 4114 is slidably connected to the rail 4113, the cooperation between the slider 4114 and the rail 4113 can better limit the movement direction of the fork mechanism 3, so as to avoid the phenomenon that the fork mechanism 3 is askew and blocked when the lifting module 41 drives the fork mechanism 3 to lift. Meanwhile, since the upper end and the lower end of the guide rail 4113 are respectively connected with the base 4111 and the top cover 4112, the stability of the guide rail 4113 is ensured, and the guide rail 4113 can be prevented from being skewed by fixing the upper end and the lower end, so that the fork mechanism 3 is further prevented from being skewed. In addition, the synchronous belt 4123 is adopted to realize the driving of the fork mechanism 3, so that the motion stability of the fork mechanism 3 can be ensured, and the phenomenon that the goods or the carrying tray falls down due to shaking in the motion process of the fork mechanism 3 is avoided.

It should be noted that, in this embodiment, the lifting driving member 4122 may be any one of a servo motor, a stepping motor, or a three-phase asynchronous motor, and may be specifically selected according to actual needs. Of course, in other embodiments of the present invention, the lifting module 41 may be another linear driving device such as a ball screw, a cylinder or a hydraulic cylinder, and is not limited to the structure of the timing belt 4123 and the timing wheel 4121 of the present embodiment.

It should be noted that, in some embodiments of the present invention, the driving mechanism 4 may be directly formed as a six-axis mechanical arm to directly complete the rotation and lifting of the fork mechanism 3, and the driving mechanism 4 is not limited to the structure including the lifting module 41 and the rotating module 42.

In some specific embodiments, as shown in fig. 5, the guide rail 4113 is provided with a chute extending along the length direction, and two side walls of the chute, which are opposite, are provided with ribs; the slider 4114 includes a slider 4141 and a sheave 41142 rotatably coupled to the slider 4141, the sheave 41142 engaging the rib. It can be appreciated that the cooperation of the grooved wheels 41142 on the slider 4114 and the ribs can further limit the movement direction of the slider 4114, so as to ensure that the fork mechanism 3 can stably lift in the vertical direction, and preferably avoid the phenomenon that the fork mechanism 3 is blocked relative to the lifting module 41.

Advantageously, the slider 4114 is provided with a support seat 41143, and the support seat 41143 is connected to the fork mechanism 3 by a connecting member, so that the stability of the fork mechanism 3 can be better ensured.

In some embodiments, as shown in fig. 3, the fork mechanism 3 includes a tray assembly 31 and a fork driving assembly 32, the tray assembly 31 includes a support frame 311, the support frame 311 is used for carrying a carrying tray, and is connected with the lifting module 41 through the connecting seat 33, the fork driving assembly 32 is used for driving the carrying tray to slide back and forth along the length direction of the support frame 311, the fork driving assembly 32 includes an electromagnetic mechanism 321 and a fork driving member 322, the electromagnetic mechanism 321 is used for adsorbing the carrying tray, and the fork driving member 322 is used for driving the electromagnetic mechanism 321 to slide back and forth along the length direction of the support frame 311.

It can be appreciated that the supporting member is connected with the lifting module 41 through the connecting seat 33, and the connecting seat 33 is connected with the synchronous belt 4123, so that the connection stability of the fork mechanism 3 and the lifting module 41 can be well ensured, and the fork mechanism 3 can be stably driven by the lifting module 41 to realize lifting. The electromagnetic mechanism 321 can ensure the stable matching of the fork mechanism 3 and the carrying tray, thereby avoiding the falling-off phenomenon of the carrying tray from the fork mechanism 3.

In this embodiment, the fork driving member 322 may be any one of a belt structure, a motor-driven ball screw mechanism, an electric push rod, an air cylinder and a hydraulic cylinder according to actual needs, and the specific type of the fork driving member 322 is not limited herein.

In some alternative embodiments, as shown in fig. 3, the electromagnetic mechanism 321 includes a sliding base 3211, an electromagnet 3212, and a resilient push rod 3213, where the sliding base 3211 is connected to the fork drive 322; the electromagnet 3212 is arranged on the sliding seat 3211 to absorb the carrying tray, the elastic ejector rod 3213 is arranged on the sliding seat 3211, the extending direction of the elastic ejector rod 3213 and the extending direction of the electromagnet 3212 are both the length direction of the sliding seat 3211, and the elastic ejector rod 3213 is used for separating the electromagnet 3212 from the carrying tray after power failure.
