Description

Technical Field

[0001] The utility model relates to the technical field of management systems, in particular to an equipment in-and-out warehouse response device based on RFID and infrared sensors. Background Art

[0002] Radio Frequency Identification (RFID) is a type of automatic identification technology. It uses radio frequency to perform non-contact two-way data communication and uses radio frequency to read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. It is considered to be one of the most promising information technologies in the 21st century. Radio frequency identification technology uses radio waves to quickly exchange information and store information without contact. It combines wireless communication with data access technology and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification and data exchange, connecting an extremely complex system in series. In the identification system, the reading, writing and communication of electronic tags are achieved through electromagnetic waves. According to the communication distance, it can be divided into near field and far field. For this reason, the data exchange method between the read / write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.

[0003] Existing in-and-out storage devices generally use detection devices such as sensors and cameras to count the number of equipment entering and leaving the warehouse, thereby providing accurate accounting data for corporate procurement, production and management. For example, Chinese Patent Publication No. CN218808198U discloses "an intelligent in-and-out storage device", whose background server can analyze pictures after introducing image algorithms. By analyzing the pictures uploaded by the camera, the type and weight of the materials that are out of or in the warehouse can be obtained. The solution is based on the existing plate chain conveyor mechanism. It only needs to add an electronic scale, a camera and a bracket. After the equipment is simply built, it only needs to be set up at the software level to be put into use quickly, and the modification cost is low. The conveyor belt moves in a cycle and can continuously drive materials out of or into the warehouse, which is highly efficient. The added infrared sensor sets the conveyor belt to stop running when the robot has not taken away the material, so as to prevent the material from scattering when the electronic scale is transferred to the bottom, which is highly safe.

[0004] However, in actual use, since the infrared sensor detection of the warehouse entry and exit response device can only detect the number of warehouse entry and exit devices, it is impossible to accurately detect the information of each device, resulting in the need for additional detection devices or manual detection records for the warehouse entry and exit devices, which increases costs.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 , an equipment in-and-out warehouse response device based on RFID and infrared sensing, comprising a conveying platform 1, an RFID identifier 2 and an infrared sensor 3, a mobile platform 4 is arranged on one side of the conveying platform 1, a mounting frame 5 is arranged on the mobile platform 4, and the RFID identifier 2 and the infrared sensor 3 are both arranged on the mounting frame 5;

[0024] A guide rail 6 is provided on the mounting frame 5, and a connecting device 7 matched with the guide rail 6 is provided on one side of the RFID identifier 2. An opening matched with the guide rail 6 is opened on the connecting device 7, and a clamping mechanism 8 matched with the guide rail 6 is provided in the connecting device 7. The clamping mechanism 8 includes two limit blocks 81, and the two limit blocks 81 pass through the opening and contact with the guide rail 6. A switch button 9 for controlling the limit block 81 is provided on one side of the connecting device 7.

[0025] In the present invention, the electronic tags on the in-and-out equipment are read and written by the RFID identifier 2, so as to achieve the purpose of identifying the target and exchanging data. The electronic tags can store a large amount of information, such as product information, inventory data, etc., making the information management more convenient and accurate. The connecting device 7 cooperates with the guide rail 6 to facilitate the adjustment of the height of the connecting device 7 and the RFID identifier 2, so that when installing the corresponding in-and-out equipment, the position of the RFID identifier 2 can be adjusted, so that it can be suitable for equipment of different volumes. When identifying equipment with a larger volume and a higher height, the connecting device 7 is moved upward to drive the RFID identifier 2 to move upward, so as to identify the electronic tag of the equipment. When the height of the equipment is low, the RFID identifier 2 is driven downward by moving the connecting device 7 downward, so as to identify the electronic tag of the equipment.

[0026] Furthermore, in this embodiment, a cavity 71 is provided in the connecting device 7, and the clamping mechanism 8 also includes a driving structure 82 arranged in the cavity 71 and cooperating with the two limit blocks 81. The positions of the two limit blocks 81 are controlled by the driving structure 82 to prevent the two limit blocks 81 from being separated from the guide rail 6 during daily use.

[0027] Furthermore, in the present embodiment, the driving structure 82 includes two connecting plates 821, and the two connecting plates 821 are respectively connected to the two limit blocks 81. The opposite ends of the two connecting plates 821 are provided with spur racks 822. A gear 823 meshing with the two spur racks 822 is rotatably provided in the cavity 71. When one connecting plate 821 moves, the spur rack 822 drives the gear 823 to rotate, and the gear 823 drives the other spur rack 822 to rotate, thereby driving the other connecting plate 821 to move, thereby realizing the two connecting plates 821 and the two limit blocks 81 to move away from or toward each other.

[0028] It should be noted that, in the present embodiment, a transmission plate 824 is slidably arranged in the cavity 71, one end of the transmission plate 824 is fixedly connected to a connecting plate 821, the transmission plate 824 passes through the cavity 71 and another connecting plate 821 and is fixedly connected to the switch button 9, and the connecting plate 821 is moved by pressing the switch button 9, and the gear 823 drives the other spur rack 822 to rotate, thereby driving the other connecting plate 821 to move.

[0029] In addition, in the present embodiment, a spring 825 is provided between the connecting plate 821 and the inner wall of the cavity 71, and a slope 826 is provided on one side of the limit block 81. When the connecting device 7 is installed, the slope of the limit block 81 contacts the guide rail 6, so that the two limit blocks 81 move away from each other. At this time, the spring 825 is squeezed and elastically deformed, thereby moving the guide rail 6 into the opening. When the guide rail 6 moves into the opening, the spring 825 resets and drives the two limit blocks 81 to move and clamp the guide rail 6. The limit blocks 81 are provided with clamping grooves that match the guide rail 6. The clamping grooves of the two limit blocks 81 abut against the guide rail 6 to generate friction, thereby preventing the connecting device 7 from sliding down and fixing the connecting device 7.

[0030] In more detail, in this embodiment, two mounting parts 11 are provided on one side of the conveying platform 1, a guide rod 12 slidably connected to the moving platform 4 is provided between the two mounting parts 11, a screw rod 13 threadedly connected to the moving platform 4 is provided between the two mounting parts 11, and a motor 14 powered by the screw rod 13 is fixedly provided on one side of the mounting part 11. The screw rod 13 is driven by the motor 14 to rotate and drive the moving platform 4 and the mounting frame 5 to move, thereby adjusting the position of the mounting frame 5, the infrared sensor 3 and the RFID identifier 2.

[0031] Working mode: When working, the electronic tags on the in-and-out equipment are read and written by the RFID reader 2, so as to achieve the purpose of identifying the target and exchanging data. The electronic tags can store a large amount of information, such as product information, inventory data, etc., making the information management more convenient and accurate;

[0032] When installing the connection device 7, the inclined surface of the limit block 81 contacts the guide rail 6, so that the two limit blocks 81 move away from each other. At this time, the spring 825 is squeezed and elastically deformed, thereby moving the guide rail 6 into the opening. When the guide rail 6 moves into the opening, the spring 825 resets and drives the two limit blocks 81 to move, clamping the guide rail 6. The limit blocks 81 are each provided with a clamping groove that matches the guide rail 6. The clamping grooves of the two limit blocks 81 abut against the guide rail 6 to generate friction, thereby preventing the connection device 7 from sliding down and fixing the connection device 7.

[0033] The motor 14 drives the screw rod 13 to rotate and drive the movable platform 4 and the mounting bracket 5 to move, thereby adjusting the positions of the mounting bracket 5, the infrared sensor 3 and the RFID identifier 2.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
