AI Technical Summary
Traditional weighing tool cabinets are difficult to measure accurately when tools are not placed properly, especially when tools are placed on the edge or corner of the base, resulting in inaccurate weighing.
The weighing assembly consists of a ring-shaped support plate and two load cells. The ring-shaped support plate has a support column that works with the placement plate. Symmetrical load cells are located below the placement plate. The placement plate is fixed to the ring-shaped support plate by the support column, and the weight is verified with the help of the control host.
The tool cabinet's weighing accuracy has been improved. The design of the ring tray and weighing sensor ensures that the weight of tools can be accurately measured no matter where they are placed, reducing errors.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0024] Reference Figure 1-3 This invention describes an intelligent weighing tool cabinet according to an embodiment of the present invention.
[0025] In one embodiment, such as Figure 1-3 As shown, an intelligent weighing tool cabinet includes a cabinet body 1, a control host and multiple storage compartments 100 on the cabinet body, a shelf 11 at the bottom of the storage compartments 100, and a weighing component below the shelf 11.
[0026] The weighing assembly includes an annular support plate 12 and a weighing sensor 13. The upper surface of the annular support plate 12 is uniformly provided with a plurality of support columns 120 along the circumference. The bottom surface of the placement plate 11 is provided with a plurality of grooves 110 that cooperate with the plurality of support columns 120. The plurality of support columns 120 are inserted into the plurality of grooves 110 one by one to fix the placement plate 11 onto the annular support plate 12.
[0027] The weighing sensor 13 includes a first weighing sensor 131 and a second weighing sensor 132. The first weighing sensor 131 and the second weighing sensor 132 are symmetrically arranged on both sides of the bottom surface of the annular support plate 12 and are respectively connected to the control host.
[0028] The above-mentioned intelligent weighing tool cabinet operates as follows: When a user places tools on the shelf 11, inaccurate weighing often occurs when the placement is off-center, such as in a corner or on one side of the shelf 11. However, in this embodiment, the shelf 11 is supported by various support columns 120 on the annular support plate 12, allowing the weight of the side or corner of the shelf 11 to be transferred to the annular support plate 12 via the nearby support columns 120. Furthermore, a first weighing sensor 131 and a second weighing sensor 132 are symmetrically arranged on both sides of the bottom surface of the annular support plate 12. These two weighing sensors 131 weigh the annular support plate 12 from both sides and send the obtained weight value to the control host, which can effectively improve the weighing accuracy.
[0029] The intelligent weighing tool cabinet provided in the above embodiment, by adopting a weighing assembly composed of an annular tray 12 and two weighing sensors 13, can solve the influence of tool placement center of gravity deviation on weighing accuracy and improve the weighing accuracy of the tool cabinet.
[0030] In this embodiment, the circular area enclosed by the multiple support columns 120 is not less than 70% of the area of the shelf 11. The circular area enclosed by the multiple support columns 120 can be 70% or more of the area of the shelf 11, for example, 80% or 90%, thereby ensuring more uniform force distribution on the annular support plate 12 and guaranteeing weighing accuracy.
[0031] In this embodiment, the weighing assembly also includes a housing, an annular support plate 12 and a weighing sensor 13 are disposed inside the housing, and a through hole is provided on the top surface of the housing for the support column 120 to pass through.
[0032] In the above embodiments, the use of a housing to house the annular tray 12 and the weighing sensor 13 can better protect the annular tray 12 and the weighing sensor 13, and prevent dust or moisture from affecting the service life of the weighing sensor 13.
[0033] In this embodiment, an RFID tag reader is provided on the top of the storage compartment 100, and each RFID tag reader is connected to the control host.
[0034] This embodiment provides an RFID tag reader on the top of the storage compartment 100, enabling the compartment to read RFID tags attached to tools and send the reading results to the control host. This allows for the identification and management of tools, facilitating tool access and making the system more intelligent.
[0035] In this embodiment, each storage compartment 100 has a compartment door and an electronic lock on its front, and each electronic lock is connected to the control host. The electronic lock is used to open and close the compartment door under the control of the control host, realizing automated management of the storage compartment's opening and closing and ensuring the security of the intelligent weighing tool cabinet.
[0036] In this embodiment, the control host is used to acquire the first weight detected by the first weighing sensor 131 and the second weight detected by the second weighing sensor 132, and when the difference between the first weight and the second weight is greater than a preset threshold, it issues a prompt signal to remind the user to readjust the position of the tool. The difference between the first weight and the second weight refers to the absolute value of the difference.
[0037] In practical applications, when the tool is placed too far off-center, uneven force may still occur on the annular support plate 12, resulting in inconsistent detection values between the first weighing sensor 131 and the second weighing sensor 132 on both sides. In this case, the control host can compare the difference between the weight detected by the first weighing sensor 131 and the second weighing sensor 132 with a preset threshold. If the difference is greater than the preset threshold, it is determined that the tool is placed too far off-center, and a prompt signal is issued to remind the user to readjust the position of the tool. This can prompt the user to place the tool in a suitable position, thereby ensuring the accuracy of weighing.
[0038] In practice, the prompting signal can be implemented in various forms. For example, an indicator light can be provided on the front of each storage compartment 100, and the control host can turn on the light in front of the corresponding storage compartment 100 to remind the user to put the tools in that storage compartment 100 back in.
[0039] In this embodiment, the control host includes a control panel 101 mounted on the cabinet 1; the control panel 101 is equipped with a touch screen, a card reader, a face recognition device and a fingerprint unlocking device, and the control panel 101 is connected to a wireless communication device.
[0040] The touch screen allows users to enter a password, while the card reader, facial recognition device, and fingerprint unlocking device can all identify the user's identity, making it convenient to store and retrieve tools from the storage compartment 100 of the aforementioned intelligent weighing tool cabinet.
[0041] In practice, the control host can display the number of the corresponding storage compartment 100 on the touch screen or send the number of the corresponding storage compartment 100 to the user terminal via wireless communication.
[0042] In this embodiment, a camera 102 is provided on the top of the cabinet 1. The camera 102 is connected to the control host. The camera 102 can collect video of the surrounding environment of the cabinet 1 and transmit it to the control host, so as to monitor the surrounding environment, ensure the safety of the stored items, and prevent illegal access and theft.
[0043] In this embodiment, a light strip 103 is also provided on the top of the cabinet 1, and the light strip 103 is connected to the control host. When the light is dim, the control host can control the light strip 103 to provide illumination, thereby improving the ease of use of the intelligent weighing tool cabinet.
[0044] In this embodiment, the cabinet 1 has a handle 104 on its side and casters 105 on its bottom. In practice, the user can move the cabinet 1 by pulling it with the handle 104 for easy movement.
[0045] Other components and operations of the intelligent weighing tool cabinet according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
