Description

Technical Field

[0001] The present invention relates to the technical field of RFID, and particularly to an RFID intelligent inventory robot based on the Internet of Things. Background Art

[0002] RFID technology is a non-contact automatic identification technology that uses radio frequency signals. It communicates with electronic tags through radio waves to achieve object identification and data exchange. RFID technology mainly consists of three core components: electronic tags, readers, and antennas. The electronic tag stores a unique identifier. The reader sends and receives signals through the antenna, reads the information in the tag, and transmits it to the central information system for processing.

[0003] A Chinese invention patent with the publication number CN212825404U discloses an intelligent file inventory robot, including: a bottom plate and a display unit. A storage box is fixed on the upper surface of the bottom plate, and a storage cavity is arranged inside the storage box. A diversion cavity is connected to the bottom of the storage cavity. A first opening is reserved on the upper surface of the storage cavity, and a movable plate is installed at the middle position of the storage cavity. A placement groove is formed on the outer wall of the movable plate. A limiting block penetrates through the placement groove, and a spring is fixed inside the placement groove. A spring is reserved on the upper surface of the movable plate, and the bottom of the movable plate is connected to a gear. The movable plate and the gear are movably connected. A connecting shaft is fixed at the middle position of the gear, and a motor is connected to the end of the connecting shaft. This intelligent file inventory robot has good accuracy in file inventory, and the files are not easily blocked after inventory, reducing the usage difficulty of the device.

[0004] In addition, due to the large number of files in the file storage, personnel need to open the file boxes and compare them one by one with the data recorded in the filing directory. Comparing all the massive files one by one is a very large workload and is not feasible for actual operation. Therefore, a large amount of manpower and time are required for the inventory work. In addition, this method has a long operation time, low work efficiency, and the data of manual operation is prone to errors, and rapid batch inventory cannot be achieved. Moreover, the files after personnel inventory need to be classified one by one by personnel to avoid file chaos affecting the subsequent taking efficiency of personnel. Therefore, the intelligent file inventory robot disclosed in Chinese invention patent CN212825404U has the problems of inability to quickly inventory and quickly classify. Summary of the Invention

[0021] Beneficial Effects

[0022] Compared with the prior art, the present invention provides an RFID intelligent inventory counting robot based on the Internet of Things, which has the following beneficial effects:

[0023] 1. When the sealing plate is attached to the suction cup, the suction cup can adsorb the files.

This avoids the need for personnel to spend a lot of manpower and time to count the files one by one, and also avoids the problem of easy errors during inventory. This not only improves the efficiency of file inventory, but also ensures the accuracy of file inventory.

[0024] 2. The roller rod is used to elastically resist the files, and the files are driven to move into the classification box under the action of the rotation of the roller rod, which increases the stability of the files when sliding on the upper surface of the inclined plate 1, prevents wrinkles from forming during the movement of the files, prevents wrinkles from forming on the upper surface of the inclined plate 1, and avoids the problem that the RFID reader cannot effectively identify wrinkled files, thereby improving the accuracy of the RFID reader's inventory.

[0025] 3. Under the action of the inclination angle in the middle of the classification box, the file fits against the side of the classification box, avoiding the problem of the classification box being blocked after the file enters the interior of the classification box. The RFID reader controls the moving distance of the collection box according to the identified file, so that the collection box drives the load slot corresponding to the file to move to the bottom of the guide plate, allowing the file to enter the interior of the classification box, thus achieving the effect of automatically classifying the files.

[0042] It should be noted that a chamfer is provided on the side of the sealing plate 2039 close to the sleeve plate 2036 , so that when the sealing plate 2039 moves away from the sleeve plate 2036 , the sealing plate 2039 cannot seal the suction cup 2034 .

[0046] It should be noted that: by setting the middle part of the inclined plate 4037 to be inclined at an angle of 45 degrees, the files can freely slide down on the upper surface of the inclined plate 4037. The middle part of the sorting box 4035 is inclined at an angle of 20 degrees, so that the files will not be blocked when entering the sorting box 4035.

[0047] The working process and principle of the above embodiment are as follows:

[0048] Initial state: The first spring 2038 is in an uncompressed state, the sealing plate 2039 is in contact with the suction cup 2034, the torsion spring 3043 is in a relaxed state, and the second spring 3048 is in an uncompressed state.

[0049] The working steps are as follows:

[0050] First, the operator puts the file into the inside of the glove box 201, and then the operator controls the slide bar 2031 to move back and forth inside the glove box 201 through the control panel 102. When the slide bar 2031 drives the connecting rod 2032 to move toward the inside of the glove box 201, the connecting rod 2032 drives the annular plate 2033 to move toward the inside of the glove box 201, and the connecting rod 2032 drives the fixed plate 2035 to move synchronously, so that the annular plate 2033 drives the suction cup 2034 to resist the file placed in the glove box 201, so that the file squeezes the suction cup 2034 to collect it. The suction cup 2034 is compressed, so that the air inside the suction cup 2034 is discharged through the gap between the file and the suction cup 2034, thereby reducing the air pressure inside the suction cup 2034, and finally causing the suction cup 2034 to adsorb the file. Then, the control panel 102 controls the slide bar 1 2031 to slide toward the outside of the cargo box 201, so that the slide bar 1 2031 drives the connecting rod 1 2032 to slide toward the outside of the cargo box 201, so that the connecting rod 1 2032 drives the circular plate 2033 and the fixed plate 1 2035 to move synchronously, so that the fixed plate 1 2035 drives the spring 1 2038 and the slide bar 2 2037 to move synchronously, so that the slide bar 1 The second slide bar 2037 drives the sealing plate 2039 to move synchronously until the second slide bar 2037 moves to the position that contacts the inner wall of the cargo box 201. At this time, the second slide bar 2037 moves to the side close to the annular plate 2033 under the contact of the cargo box 201, so that the second slide bar 2037 squeezes the spring 1 2038 to contract, so that the second slide bar 2037 drives the sealing plate 2039 to move toward the inside of the suction cup 2034, until the sealing plate 2039 is separated from the inner wall of the suction cup 2034, at this time, the external air enters the inside of the suction cup 2034 through the gap between the sealing plate 2039 and the suction cup 2034 , so that the air pressure inside the suction cup 2034 is consistent with the air pressure outside, so that the suction cup 2034 is separated from the file. When the sealing plate 2039 is in contact with the suction cup 2034, the suction cup 2034 can adsorb the file. When the sealing plate 2039 is separated from the suction cup 2034, the suction cup 2034 is separated from the file, thereby achieving the effect of automatically delivering the file, avoiding the need for personnel to spend a lot of manpower and time to count the files one by one, and also avoiding the problem of easy errors in personnel inventory, which not only improves the efficiency of file inventory, but also ensures the accuracy of file inventory.

[0051] When the suction cup 2034 is separated from the file, the file will fall onto the upper surface of the inclined plate 1 4037, so that the file slides downward along the upper surface of the inclined plate 1 4037. When the bottom end of the file moves to a position where it contacts the limit plate 3049, the laser monitor 3046 detects that the position of the file meets the predetermined setting, and the laser monitor 3046 controls the sliding bar 302 and the roller bar 3045 to rotate, so that the sliding bar 302 drives the torsion spring 3043 and the sleeve plate 2 3041 to rotate synchronously, so that the sleeve plate 2 3041 drives the contact plate 3042 to flip toward the side close to the limit plate 3049, so that the contact plate 3042 resists the limit plate 3049 and slides downward inside the guide plate 3047, thereby causing the guide plate 3047 to squeeze the second spring 3048 to contract, so that the limit plate 3049 enters the guide plate 3047 completely. At the same time, the contact plate 3042 drives the roller rod 3045 to rotate to a position in contact with the file, and under the action of the second sleeve plate 3041 continuing to rotate, The roller rod 3045 is in contact with the file, and the roller rod 3045 remains motionless under the contact of the file. When the sliding bar 302 continues to rotate, the roller rod 3045 drives the contact plate 3042 and the sleeve plate 2 3041 to remain motionless, and the inventory unit 300 drives the torsion spring 3043 to rotate, so that the roller rod 3045 elastically contacts the file, and the file moves downward under the drive of the rotation of the roller rod 3045. The roller rod 3045 rotates to move the files into the classification box 4035, thereby increasing the stability of the files when they slide on the upper surface of the inclined plate 4037, preventing wrinkles from forming during the movement of the files, and preventing wrinkles from blocking the upper surface of the inclined plate 4037. This also avoids the problem that the RFID identifier 4039 cannot effectively identify wrinkled files, thereby improving the accuracy of the inventory of the RFID identifier 4039.

[0052] When the file slides on the upper surface of the inclined plate 4037, the RFID reader 4039 can identify the file, and the RFID reader 4039 controls the extension degree of the telescopic rod 4031. Then, the telescopic rod 4031 drives the corresponding sorting box 4035 to move in the direction of the falling file through the collection box 4032 and the loading groove 4034, so that the file falls into the interior of the sorting box 4035. After the file falls into the interior of the sorting box 4035, under the action of the inclination angle in the middle of the sorting box 4035, the file fits against the side of the sorting box 4035, avoiding the problem of blockage of the sorting box 4035 after the file enters the interior of the sorting box 4035. The RFID reader 4039 controls the moving distance of the collection box 4032 according to the identified file, so that the collection box 4032 drives the corresponding loading groove 4034 of the file to move to the bottom of the guide plate 3047, enabling the file to enter the interior of the sorting box 4035, thus achieving the effect of automatically sorting the files.
