Technical Field

[0001] This utility model relates to the field of automated warehouse technology, specifically to an automated warehouse inventory management device. Background Technology

[0002] In the warehousing and logistics industry, labor costs and storage expenses account for a significant proportion. To reduce these costs, companies are seeking automated and intelligent warehousing solutions. Automated inventory management systems (AIMs), as an important component of automated warehouses, enable automatic inventory counting and management, thereby significantly reducing labor costs and improving work efficiency.

[0003] A search revealed Chinese patent application number 201821300573.6, which discloses an automated inventory management device for an automated warehouse. The device includes a stacker crane, a warehouse management server, and shelving. The stacker crane is signal-connected to the warehouse management server. An inventory counting device is detachably connected to the side wall of the stacker crane. The inventory counting device includes a fixed RFID reader, an RFID antenna, a wireless access point (AP), and a power supply. The fixed RFID reader is signal-connected to the warehouse management server via the wireless AP. The shelving is equipped with pallets, each with a pallet tag on both sides. The RFID antenna is used to identify the pallet tags. This utility model provides an automated inventory management device for an automated warehouse that can automatically and accurately identify pallet information and quickly calculate stored material information, achieving automation, informatization, and intelligence in automated warehouse inventory management.

[0004] However, the aforementioned automated inventory control device for automated warehouses still has the following drawbacks:

[0005] Because the automatic inventory system lacks a clear connection method, the connection between the inventory device and the stacker crane sidewall may not be tight enough, making it susceptible to detachment or loosening due to vibration or external forces. Therefore, we need an automatic inventory system for automated warehouses to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: an automatic inventory device for a three-dimensional warehouse, including a mobile seat 1 with casters and a warehouse management server. A support frame 2 is installed on the surface of the mobile seat 1. The support frame 2 is arranged in an inverted U-shape. Lifting components are provided on the inner walls of both sides of the support frame 2. A loading platform 4 is installed on one side of the lifting components. Multiple anti-slip plates 401 are installed inside the surface of the loading platform 4. An inventory counting device 9 is installed on the outer wall of one side of the loading platform 4. A fixing plate 8 is fixedly installed on the side wall of the loading platform 4. A limiting groove 804 is opened inside the fixing plate 8. A limiting block 803 is fixedly installed on the side wall of the inventory counting device 9. The limiting block 803 is inserted into the limiting groove 804. A base plate 7 is fixedly installed at the bottom end of the fixing plate 8. The bottom end of the inventory counting device 9 is placed on the surface of the base plate 7.

[0023] In use, by inserting the limiting block 803, which is fixedly installed on the side wall of the inventory device 9, into the limiting groove 804 of the side wall fixing plate 8 of the loading platform 4, the structural stability between the inventory device 9 and the loading platform 4 is enhanced. Even in the complex environment inside the warehouse, if subjected to slight collisions or vibrations, the inventory device 9 can remain in place and is not easy to fall off or shift. The design of the limiting block 803 and the limiting groove 804 not only provides a stable connection, but also makes the installation and disassembly process of the inventory device 9 simple and quick.

[0024] The lifting assembly includes a drive motor 3, a threaded rod 301, and a lifting groove 303. The lifting groove 303 is formed on the inner walls of both sides of the support frame 2. The output shaft of the drive motor 3 is connected to one end of the threaded rod 301. The other end of the threaded rod 301 passes through the support frame 2 and is rotatably mounted on the inner wall of one of the lifting grooves 303. One end of the loading platform 4 is threadedly connected to the surface of the threaded rod 301. The drive motor 3 is connected to the threaded rod 301 through its output shaft, which can precisely control the rotation speed and direction of the threaded rod 301. Since one end of the loading platform 4 is threadedly connected to the surface of the threaded rod 301, the rotation of the threaded rod 301 is converted into the vertical lifting motion of the loading platform 4.

[0025] The other end of the loading platform 4 is connected to a fixing rod 302. The two ends of the fixing rod 302 are installed on the inner walls of the two sides of another lifting groove 303. The other end of the loading platform 4 is sleeved on the surface of the fixing rod 302. The design of the fixing rod 302 provides additional support points for the loading platform 4, making the loading platform 4 more stable during lifting. Especially when carrying heavy goods, the fixing rod 302 can effectively prevent the loading platform 4 from tilting or shaking due to uneven force.

[0026] The inventory device 9 includes an RFID fixed reader 901, an RFID antenna 905, a wireless AP 904, and a power supply 902. The RFID fixed reader 901 is connected to the warehouse management server via the wireless AP 904. The combined use of the RFID fixed reader 901 and the RFID antenna 905 enables rapid and accurate identification of goods in the warehouse. This non-contact identification method improves inventory efficiency and reduces manual intervention and error rates.

[0027] The power supply 902 is a UPS power supply. The RFID fixed reader 901 and the wireless AP 904 are both electrically connected to the UPS power supply. The wireless AP 904 is also equipped with a wireless signal enhancer 903. In the event of power failure or voltage fluctuation, the UPS power supply can immediately switch to backup power to ensure the normal operation of the reader and the wireless AP 904, thereby avoiding the interruption of inventory operations.

[0028] Both the fixing plate 8 and the limiting block 803 have threaded holes 801 on one side. A bolt 802 is installed on one side of the fixing plate 8. One end of the bolt 802 is threaded into the limiting block 803 through the threaded hole 801. The threaded connection design allows the fixing plate 8, the limiting block 803 and the bolt 802 to be reused. When replacement or maintenance is required, simply loosen the bolt 802 and remove it to separate and reassemble the components, reducing maintenance costs.

[0029] A stabilizing block 5 is installed on one side of the bottom of the support frame 2. The bottom of the stabilizing block 5 is installed on one side of the surface of the moving base 1. A control panel 6 is installed on the side wall of the stabilizing block 5. The control panel 6 is electrically connected to the drive motor 3 and the inventory device 9. The design of the stabilizing block 5 provides additional support points for the support frame 2, enhancing the stability of the entire device during movement or operation. Especially when carrying heavy goods or moving at high speed, the stabilizing block 5 can effectively prevent the device from tilting or overturning due to uneven force, thereby ensuring the accuracy and safety of the inventory operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
