Description

Technical Field

[0001] This invention relates to the field of RFID technology, specifically to an RFID intelligent inventory robot based on the Internet of Things. Background Technology

[0002] RFID technology is a non-contact automatic identification technology that uses radio frequency signals. It communicates with electronic tags via radio waves to identify objects and exchange data. RFID technology mainly consists of three core components: electronic tags, readers, and antennas. Electronic tags store unique identifiers, and readers send and receive signals through antennas to read the information in the tags and transmit it to a central information system for processing.

[0003] Chinese invention patent CN212825404U discloses an intelligent archive inventory robot, comprising: a base plate and a display unit. A storage box is fixed to the upper surface of the base plate, and the storage box contains a storage cavity. A flow guide 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 in the middle of the storage cavity. A storage groove is formed on the outer wall of the movable plate, and a limit block passes through the inside of the storage groove. A spring is fixed inside the storage groove. A spring is reserved on the upper surface of the movable plate, and a gear is connected to the bottom of the movable plate. The movable plate and the gear are movably connected. A connecting shaft is fixed in the middle of the gear, and a motor is connected to the end of the connecting shaft. This intelligent archive inventory robot has good accuracy in inventorying archives, and archives are less likely to become clogged after inventory, reducing the difficulty of using the device.

[0004] Furthermore, due to the massive number of files in the archives, personnel need to open the file boxes and compare them one by one with the data recorded in the filing catalog. The workload of opening and comparing all the massive files is enormous and not feasible in practice. Therefore, a lot of manpower and time are required for the inventory work. In addition, this method is time-consuming, inefficient, and prone to errors due to human operation, making it impossible to achieve rapid batch inventory. Moreover, after the files are inventoried, they need to be classified by personnel to avoid the files being disorganized and affecting the efficiency of subsequent personnel in retrieving them. Therefore, the intelligent archive inventory robot disclosed in Chinese invention patent CN212825404U cannot quickly inventory and classify the files. Summary of the Invention

A limit plate is slidably connected inside the guide plate.

[0016] Preferably, the two ends of the torsion spring are fixedly connected to the slide rod three and the sleeve two, respectively, and the spring two is fixedly connected to the limiting plate.

[0017] Preferably, the slide bar three is electrically connected to the laser monitoring instrument, and the size of the roller bar is larger than the size of the contact plate.

[0021] Beneficial effects

[0022] Compared with existing technologies, this invention provides an RFID-based intelligent inventory robot based on the Internet of Things, which has the following advantages:

[0023] 1. When the sealing plate is attached to the suction cup, the suction cup can adsorb the file. When the sealing plate is separated from the suction cup, the suction cup is separated from the file, realizing the effect of automatic file delivery. 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 errors that are easy to occur when personnel count files. This not only improves the efficiency of file count, but also ensures the accuracy of file count.

[0024] 2. The roller rods provide elastic resistance to the files, and the rotation of the roller rods moves the files into the sorting box. This increases the stability of the files when sliding on the upper surface of the inclined plate, prevents wrinkles from forming during the movement of the files, and also prevents wrinkles from blocking the upper surface of the inclined plate. It also avoids the problem of the RFID reader being unable to effectively identify wrinkled files, thereby improving the accuracy of the RFID reader's inventory.

[0025] 3. The tilt angle of the middle part of the sorting box makes the files fit snugly against the side of the sorting box, avoiding the problem of the sorting box being blocked after the files enter the sorting box. The RFID reader controls the movement distance of the collection box according to the identified files, so that the collection box moves the corresponding loading slot to the bottom of the guide plate, allowing the files to enter the sorting box, thus achieving the effect of automatic sorting of files.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] See attached document Figures 1 to 8 As shown, an RFID-based intelligent inventory robot based on the Internet of Things includes an inventory box 101 and a control panel 102, with the control panel 102 fixedly connected to the top of the inventory box 101.

[0038] The delivery unit 200 includes a container 201 fixedly connected to the upper surface of the inventory box 101, and an adsorption component 202 disposed inside the container 201.

[0039] The inventory unit 300 includes a fixing block 301 symmetrically fixed to the side wall of the inventory box 101, a sliding rod 302 rotatably connected between the two fixing blocks 301, and an anti-blocking component 303 disposed on the outside of the sliding rod 302;

[0040] The sorting unit 400 includes a second groove 401 formed at the bottom of the inner cavity of the inventory box 101, and a collection component 402 disposed at the bottom of the inventory box 101.

[0041] Furthermore, the adsorption assembly 202 includes a slide rod 2031 slidably connected inside the container 201. The slide rod 2031 is electrically connected to an external control device. Connecting rods 2032 are symmetrically fixedly connected to the outer wall of the slide rod 2031. A circular ring plate 2033 is fixedly connected between the two connecting rods 2032. A suction cup 2034 is fixedly connected to the side of the circular ring plate 2033 away from the connecting rods 2032. A fixing device is fixedly connected between the two connecting rods 2032. Plate 1 2035, fixed plate 1 2036 is fixedly connected to the middle of plate 1 2035, slide rod 2037 is slidably connected to the middle of slide rod 2036, spring 1 2038 is fixedly connected between slide rod 2036 and slide rod 2037, spring 1 2038 is sleeved on the outer wall of slide rod 2037, sealing plate 2039 is fixedly connected to the end of slide rod 2037 away from spring 1 2038, the size of sealing plate 2039 is adapted to the inner cavity size of suction cup 2034.

[0042] It should be noted that the sealing plate 2039 has a chamfer on the side near the sleeve plate 2036, which enables the sealing plate 2039 to be unable to seal the suction cup 2034 when it moves away from the sleeve plate 2036.

[0043] Furthermore, the anti-blocking component 303 includes two sleeve plates 3041 symmetrically rotatably connected to the outer wall of the slide rod 302. Each of the two sleeve plates 3041 has a contact plate 3042 fixedly connected to the side away from the slide rod 302. Both ends of the slide rod 302 are fitted with torsion springs 3043, with both ends of the torsion springs 3043 fixedly connected to the slide rod 302 and the sleeve plates 3041 respectively. The lower surfaces of the two fixing blocks 301 are fixedly connected with fixing plates 3044. A roller rod 3045 is rotatably connected between the two contact plates 3042. The size of the plate is larger than that of the contact plate 3042. The laser monitor 3046 is fixedly connected to the side of the two fixed plates 3044 near 2045. The slide bar 302 is electrically connected to the laser monitor 3046. The guide plate 3047 is fixedly connected between the bottom ends of the two fixed plates 3044. Three springs 3048 are fixedly connected in a linear array on the inner wall of the guide plate 3047. The guide plate 3049 is slidably connected inside the guide plate 3047. The springs 3048 are fixedly connected to the limit plate 3049.

[0044] It should be noted that the limiting plate 3049 is trapezoidal in shape, narrower at the top and wider at the bottom, which can limit the movement of the placed file. The laser monitor 3046 has the function of identifying the position of the file.

[0045] Furthermore, the collection assembly 402 includes telescopic rods 4031 symmetrically fixedly connected inside the second groove 401. A collection box 4032 is fixedly connected between the telescopic ends of the two telescopic rods 4031. A guide rod 4033 is fixedly connected to the outer wall of the collection box 4032 on the side away from the telescopic rods 4031. The guide rod 4033 has three loading slots 4034 arranged in a linear array inside. A sorting box 4035 is inserted into each of the three loading slots 4034. The middle of the sorting box 4035 is inclined at a 20-degree angle. The inventory box 101 has a first groove 4036 at the top of its inner cavity. An inclined plate 4037 is fixedly connected to the inner wall of the first groove 4036. The middle part of the inclined plate 4037 is inclined at a 45-degree angle and is transparent. A connecting rod 4038 is symmetrically fixedly connected to the inner wall of the first groove 4036. An RFID reader 4039 is fixedly connected between the two connecting rods 4038. There is an electrical connection between the second groove 401 and the RFID reader 4039.

[0046] It should be noted that by setting the middle of the inclined plate 4037 at a 45-degree angle, the files can slide freely downwards on the upper surface of the inclined plate 4037. The middle of the sorting box 4035 is tilted at a 20-degree angle, so that the files will not be blocked when entering the sorting box 4035.

[0047] The following describes the working process and principle of the above embodiments:

[0048] The initial state is as follows: Spring 1 2038 is in an uncompressed state, sealing plate 2039 and suction cup 2034 are in a close contact state, torsion spring 3043 is in a relaxed state, and spring 2 3048 is in an uncompressed state.

[0049] The work steps are as follows:

[0050] First, the operator places the file into the storage compartment 201. Then, the operator uses the control panel 102 to control the sliding rod 2031 to move back and forth inside the storage compartment 201. When the sliding rod 2031 moves the connecting rod 2032 into the storage compartment 201, the connecting rod 2032 moves the annular plate 2033 closer to the inside of the storage compartment 201. This causes the connecting rod 2032 to move the fixing plate 2035 synchronously, causing the annular plate 2033 to move the suction cup 2034 against the file placed inside the storage compartment 201, causing the file to compress the suction cup 2034 and retract. The compression causes the air inside the suction cup 2034 to escape through the gap between the file and the suction cup 2034, thereby reducing the air pressure inside the suction cup 2034 and ultimately allowing the suction cup 2034 to adhere to the file. Then, the control panel 102 controls the slide rod 2031 to slide outwards from the storage box 201. This causes the slide rod 2031 to drive the connecting rod 2032 to slide outwards from the storage box 201. The connecting rod 2032 then drives the annular plate 2033 and the fixing plate 2035 to move synchronously. The fixing plate 2035 then drives the spring 2038 and the slide rod 2037 to move synchronously. The sliding rod 2037 moves synchronously with the sealing plate 2039 until it reaches a position where it contacts the inner wall of the cargo box 201. At this point, the sliding rod 2037 moves towards the side closer to the annular plate 2033 under the action of the cargo box 201, causing it to compress the spring 2038. This causes the sliding rod 2037 to move the sealing plate 2039 towards the inside of the suction cup 2034 until the sealing plate 2039 disengages from the inner wall of the suction cup 2034. At this point, external air enters the inside of the suction cup 2034 through the gap between the sealing plate 2039 and the suction cup 2034. This allows the air pressure inside the suction cup 2034 to match the external air pressure, thus detaching the suction cup 2034 from the file. When the sealing plate 2039 is attached to the suction cup 2034, the suction cup 2034 can adsorb the file. When the sealing plate 2039 is detached from the suction cup 2034, the suction cup 2034 is detached from the file. This achieves the effect of automatic file delivery, avoiding the need for personnel to spend a lot of manpower and time to inventory the files one by one, and also avoiding the problems that are prone to errors when personnel are inventorying. This not only improves the efficiency of file inventory but also ensures the accuracy of file inventory.

[0051] After the suction cup 2034 detaches from the file, the file falls onto the upper surface of the inclined plate 4037, causing it to slide downwards along this surface. When the bottom of the file touches the limit plate 3049, the laser monitor 3046 detects that the file's position matches a predetermined setting. The laser monitor 3046 then controls the slide bar 302 and roller bar 3045 to rotate, causing the slide bar 302 to drive the torsion spring 3043 and the sleeve plate 3041 to rotate synchronously. 3041 drives the contact plate 3042 to flip towards the side closer to the limiting plate 3049, causing the contact plate 3042 to slide downwards inside the guide plate 3047 against the limiting plate 3049. This causes the guide plate 3047 to compress the second spring 3048, allowing the limiting plate 3049 to fully enter the guide plate 3047. Simultaneously, the contact plate 3042 drives the roller rod 3045 to rotate to the position of contact with the file, and under the continued rotation of the sleeve plate 3041... The roller rod 3045 comes into contact with the file, thus keeping the roller rod 3045 stationary under the resistance of the file. When the slide bar 302 continues to rotate, the roller rod 3045 drives the contact plate 3042 and the sleeve plate 3041 to remain stationary, which in turn causes the inventory unit 300 to drive the torsion spring 3043 to rotate. This causes the roller rod 3045 to elastically contact the file, and the file moves downward under the action of the rotation of the roller rod 3045. The roller rod 3045 then aligns with the file. The file is elastically resisted and moved into the sorting box 4035 by the rotation of the roller rod 3045. This increases the stability of the file when sliding on the upper surface of the inclined plate 4037, prevents wrinkles from forming during the movement of the file, and also prevents wrinkles from blocking the upper surface of the inclined plate 4037. It also avoids the problem that the RFID reader 4039 cannot effectively identify wrinkled files, thereby improving the accuracy of the inventory count by the RFID reader 4039.

[0052] As the file slides on the upper surface of the inclined plate 4037, the RFID reader 4039 identifies the file and controls the extension of the telescopic rod 4031. This telescopic rod 4031 then moves the corresponding sorting box 4035 in the direction the file falls, via the collection box 4032 and the loading slot 4034. The file then falls into the sorting box 4035. Once inside, the tilt angle of the sorting box 4035 ensures it fits snugly against the side, preventing blockage. The RFID reader 4039 controls the movement of the collection box 4032 based on the identified file, causing the collection box 4032 to move the corresponding loading slot 4034 to the bottom of the guide plate 3047, allowing the file to enter the sorting box 4035. This achieves automatic file sorting.
