Description

Technical Field

[0001] The utility model relates to the technical field of vending cabinets, in particular to an intelligent vending cabinet capable of automatically closing and settling accounts. Background Art

[0002] Smart unmanned vending machines refer to unmanned vending machines that enable users to "open the door by scanning a code, shop freely, and automatically settle the bill when the door is closed". Smart unmanned vending machines use computers, sensors, surveillance cameras and other technologies to display, store, quickly sell and automatically pay for goods.

[0003] Existing smart vending machines can detect whether the cabinet door is locked, and can issue an alarm when the cabinet door is not closed to remind the staff. For example, Chinese patent application number CN202021150991.9 discloses an open smart vending machine, including a cabinet body with an electronic lock, multiple layers of shelves in the cabinet body, and an image acquisition device above each layer of shelves; the cabinet door can be rotatably installed at the cabinet opening of the cabinet body and can be opened or closed relative to the cabinet body, and the cabinet door is provided with a lock buckle that cooperates with the electronic lock.

[0004] This smart vending machine can only realize the reminder function after detecting that the cabinet door is not closed. The staff needs to go to the cabinet door and manually close the cabinet door, which makes closing the cabinet door inconvenient. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides a technical solution: an intelligent vending machine with automatic door closing and settlement, comprising a cabinet body 1, a cabinet door 2 being rotatably connected to one side of the cabinet body 1, a first camera 3 being installed on one side of the cabinet body 1, a second camera 4 being installed on the side of the cabinet body 1 close to the cabinet door 2, a push rod 5 being rotatably connected to one side of the cabinet body 1, an output end of the push rod 5 being rotatably connected to the cabinet door 2, a PLC controller being installed inside the cabinet body 1, the PLC controller being electrically connected to the first camera 3, the second camera 4, and the push rod 5, an identification camera 6 being installed on the upper side of the cabinet body 1, and the identification camera 6 being capable of Identify and capture the goods taken by the consumer, then compare the captured data with the goods in the background database and perform big data analysis to identify what kind of goods are taken, and then realize the settlement of the goods. This is an existing technology and will not be repeated here. The first camera 3 is facing the cabinet door 2, and the second camera 4 is facing the area in front of the cabinet 1 where the consumer stands. The first camera 3 and the second camera 4 have face recognition function and body recognition function respectively. Applying face recognition and body recognition functions to the camera is an existing technology and will not be repeated here. The push rod 5 is an electric push rod.

[0025] When working, the first camera 3 and the second camera 4 identify the consumer in front of the cabinet 1. After the consumer takes the goods and leaves, the first camera 3 and the second camera 4 cannot identify the consumer, and thus send an electrical signal to the PLC controller, causing the PLC controller to control the push rod 5 to retract, and the push rod 5 drives the cabinet door 2 to close, thereby realizing the automatic closing of the cabinet door 2.

[0026] See also Figure 1-4 The utility model provides a technical solution: a pressure sensor 7 is installed on one side of the cabinet 1 close to the push rod 5, and the position of the pressure sensor 7 corresponds to the push rod 5.

[0027] During operation, when the push rod 5 contracts to close the cabinet door 2, the push rod 5 will contact the pressure sensor 7, and the pressure sensor 7 will transmit an electrical signal to the PLC controller. The PLC controller controls the push rod 5 to stop contracting and controls the first camera 3 and the second camera 4 to turn off.

[0028] See also Figure 1-4 The utility model provides a technical solution: a baffle 8 is connected to the side of the cabinet 1 close to the push rod 5, and the baffle 8 is located above the push rod 5.

[0029] During operation, through the setting of the baffle 8, if the consumer takes out the goods and puts them back into the cabinet 1, water drops may be generated on the surface of the goods. The baffle 8 can prevent the water drops on the surface of the goods from falling onto the push rod 5.

[0030] See also Figure 1-4The utility model provides a technical solution: a plurality of support rods 9 are longitudinally connected to the side of the lower surface of the baffle 8 away from the push rod 5, and the lower ends of the support rods 9 are connected to the cabinet 1.

[0031] During operation, the support rod 9 can support the baffle 8 and prevent any large objects placed outside from entering the working area of ​​the push rod 5.

[0032] See also Figure 1-4 The utility model provides a technical solution: a rubber sheet 10 is connected to the side of the pressure sensor 7 close to the push rod 5.

[0033] During operation, the rubber sheet 10 can play a buffering role between the pressure sensor 7 and the push rod 5 through the arrangement of the rubber sheet 10 , and reduce the wear generated when the pressure sensor 7 and the push rod 5 are in contact.

[0034] See also Figure 1-4 , the utility model provides a technical solution: the support rod 9 is made of stainless steel.

[0035] During operation, the support rod 9 made of stainless steel has better strength, which is beneficial to effectively support the baffle 8.

[0036] See also Figure 1-4 The utility model provides a technical solution: the first camera 3 is arranged inside the cabinet 1 near the cabinet door 2.

[0037] When in operation, the first camera 3 is set close to the cabinet door 2 so that the position of the first camera 3 is close to the position of the goods at the edge, thereby effectively reducing the obstruction of the goods to the detection range of the first camera 3.

[0038] In summary, when the cabinet door 2 is opened, the push rod 5 is stretched by the cabinet door 2 and rotates in the direction away from the pressure sensor 7. At this time, the pressure sensor 7 is no longer in contact with the push rod 5, and the PLC controller no longer receives the electrical signal from the pressure sensor 7, so that the PLC controller controls the first camera 3 and the second camera 4 to turn on and identify the consumer in front of the cabinet 1. After the consumer takes the goods and leaves, the first camera 3 and the second camera 4 cannot identify the consumer, thereby sending an electrical signal to the PLC controller, causing the PLC controller to control the push rod 5 to retract, and the push rod 5 drives the cabinet door 2 to close. At the same time, the push rod 5 rotates toward the pressure sensor 7. After the push rod 5 contacts the pressure sensor 7, the pressure sensor 7 transmits the electrical signal to the PLC controller, and the PLC controller controls the push rod 5 to stop retracting and controls the first camera 3 and the second camera 4 to turn off. At this time, the cabinet door 2 and the cabinet 1 are already in contact, thereby realizing the automatic closing of the cabinet door 2.
