Description

Technical Field

[0001] This utility model belongs to the field of intelligent weighing scales, and particularly relates to intelligent warehouse weighing scales. Background Technology

[0002] In scenarios such as canteens and warehouses, electronic scales are required for the handling of fresh food entering and leaving the warehouse. Traditional electronic scales have limited functions, only performing basic weighing. The recording of data for fresh food requires manual operation, which is inefficient and prone to errors. Currently, some smart scales with camera functions have fixed cameras to take pictures of the weighed items, achieving a certain degree of informatization and intelligence. However, in actual use, because the cameras are fixedly installed, the shooting angle and height cannot be adjusted. When facing food or containers of different sizes and heights, the fixed perspective may lead to incomplete shooting, image distortion, or blind spots, affecting the accuracy of fresh food identification and the authenticity of the recorded images for traceability. Secondly, the cameras are easily exposed to complex environments such as warehouses or canteens for a long time, which can accumulate oil and dust or be damaged by bumps during the handling of goods, affecting their service life. Moreover, the smart scales currently in use lack effective anti-cheating mechanisms. Video recording alone cannot effectively monitor and prevent cheating behaviors such as "stepping on the scale" to tamper with the weight by applying extra force. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent warehouse scale to solve the problems of current smart scales where the camera is fixedly installed with no adjustable shooting angle or height. When facing food or containers of different sizes and heights, the fixed perspective may lead to incomplete shooting, image distortion, or blind spots, affecting the accuracy of fresh food identification and the authenticity of recorded images for traceability. Secondly, the camera is easily exposed to complex environments such as warehouses or canteens for a long time, which can easily accumulate oil and dust or be damaged by bumps during the handling of goods, affecting its service life. Furthermore, current smart scales lack effective anti-cheating mechanisms, and video recording alone cannot effectively monitor and prevent cheating behaviors such as "stepping on the scale" to tamper with the weight by applying extra force.

[0004] To achieve the above objectives, the specific technical solution of this utility model intelligent warehouse scale is as follows: The intelligent warehouse weighing scale includes a base; a weighing tray is mounted on the base; a column is mounted on one side of the weighing tray; a screw-slide rail mechanism driven by a first motor is mounted on the column; a main body is fixedly mounted on the sliding block of the screw-slide rail mechanism; a storage groove is provided in the middle of the main body, and a flip plate is rotatably mounted on the top of the storage groove via a rotating shaft; the flip plate is driven by a second motor mounted on one side of the main body and can flip between a horizontal working position and a position where it is folded into the storage groove; a first camera is mounted on the side of the flip plate opposite the weighing tray when the flip plate is in the horizontal working position; second cameras are mounted on the main body and on both sides of the storage groove; and multiple acoustic sensors are mounted on the outside of the weighing tray on the base.

[0005] Furthermore, a ring of fill lights is arranged around the perimeter of the first camera.

[0006] Furthermore, the main body has multiple strip lights below the second camera; the strip lights include an illumination mode for supplementary lighting and a flashing warning mode.

[0007] Furthermore, the main body is provided with a touch screen display on the lower side of the storage slot.

[0008] Furthermore, there are four acoustic wave sensors, which are respectively set on the outer side of the four corners of the weighing tray on the base, and emit and receive detection acoustic waves to the outer periphery of the weighing tray.

[0009] Furthermore, the base is provided with multiple wheels at its bottom.

[0010] This utility model of intelligent warehouse weighing scale has the following advantages: The main body can be freely raised and lowered via a screw-rail mechanism driven by a first motor, allowing for flexible adjustment of the height of the first and second cameras, enabling effective filming of food containers of different heights. A second motor drives a flip plate to house the first camera, providing a suitable shooting angle during fresh food storage and warehousing operations. When not in use, the flip plate and first camera can be stored in a storage slot, effectively preventing the first camera from being bumped during movement, cleaning, or goods handling, avoiding dust and oil contamination, and extending the lifespan of the equipment. During storage or warehousing operations, two symmetrically arranged second cameras and multiple acoustic sensors work together. The second cameras record the worker's actions, while the acoustic sensors detect any abnormal objects approaching the weighing tray. If any abnormal operation or object is detected, the weighing process stops and recording begins, and the second cameras record the situation. Attached Figure Description

[0012] To better understand the purpose, structure, and function of this utility model, the intelligent warehouse scale of this utility model will be described in further detail below with reference to the accompanying drawings.

[0013] like Figure 1-3 As shown, the present invention, an intelligent warehouse weighing scale, includes a base 1; a weighing tray 2 is mounted on the base 1; a column 3 is mounted on one side of the weighing tray 2 on the base 1; a screw-slide rail mechanism 4 driven by a first motor 5 is mounted on the column 3; a main body 6 is fixedly mounted on the sliding block of the screw-slide rail mechanism 4; a storage groove 7 is provided in the middle of the main body 6, and a flip plate 8 is rotatably mounted on the top of the storage groove 7 via a rotating shaft; the flip plate 8 is driven by a second motor 9 mounted on one side of the main body 6 and can flip between a horizontal working position and a position where it is folded into the storage groove 7; a first camera 10 is mounted on the side of the flip plate 8 opposite the weighing tray 2 when the flip plate 8 is in the horizontal working position; second cameras 11 are mounted on the main body 6 and on both sides of the storage groove 7; and multiple acoustic sensors 12 are mounted on the outside of the weighing tray 2 on the base 1.

[0014] Combination Figure 1-3As shown, during use, staff place the fresh ingredients to be stored or removed onto the weighing tray 2. The scale detects the weight and begins weighing, activating the first motor 5. This first motor 5 drives the lead screw slide mechanism 4, raising the main body 6 from the bottom. Then, the second motor 9 starts, rotating the flip plate 8 stored in the storage slot 7 outwards, aligning the first camera 10 with the weighing tray 2. The first camera 10 detects the position of the fresh ingredients on the weighing tray 2. If the position of the first camera 10 relative to the ingredients is incorrect, the first motor 5 and the second motor 9 adjust the position of the first camera 10 to ensure proper positioning. The system ensures accurate filming and proper food identification. Simultaneously, two symmetrically arranged second cameras 11 on the main body 6 are activated to film the weighing area and staff. Multiple acoustic sensors 12 are activated and enter standby monitoring mode. The weight of the food is weighed through the weighing tray 2, and the type of food is identified through the first camera 10. After the food is weighed and the information is recorded for storage or out of the warehouse, the staff removes the food from the weighing tray 2. When the storage scale detects that no further weighing has been performed for a certain period of time, the second motor 9 is activated to rotate the flip plate 8 into the storage slot 7, and the first motor 5 is activated to lower the main body 6 into standby mode.

[0015] like Figure 3 As shown, a ring-shaped fill light 13 is arranged around the first camera 10. When fresh food is stored and taken out of the warehouse, the ring-shaped fill light 13 provides uniform and shadow-free illumination for the first camera 10, which effectively overcomes the impact of insufficient ambient light or strong light shadows on the image quality of the food, ensures the accuracy of AI recognition and the clarity of the photos, and improves the reliability of data traceability.

[0016] like Figure 1-2 As shown, the main body 6 has multiple strip lights 14 below the second camera 11. The strip lights 14 include an illumination mode for supplementary lighting and a flashing warning mode. When weighing fresh food normally, they are in illumination mode to provide supplementary lighting for the weighing area and the face of the staff, assisting the second camera 11 in obtaining clearer monitoring and facial recognition images. When the second camera 11 detects abnormal operation behavior of the staff or the sound wave sensor 12 detects that an object is approaching the weighing tray 2, it enters the warning mode and flashes to warn. The flashing can provide an immediate and intuitive on-site alarm for the detected abnormal behavior (such as approaching the sound wave detection area), enhancing the system's proactive deterrence and human-computer interaction experience.

[0017] like Figure 1-3As shown, a touch screen 15 is provided on the lower side of the storage slot 7 of the main body 6. The touch screen 15 displays information such as the type of ingredients, weight, and personnel entering the warehouse. Staff can confirm the information through touch operation. At the same time, the touch screen 15 can be adjusted in height with the height-adjustable main body 6, so that the operator can clearly view the information and perform touch operation without frequently bending over or deliberately looking down. This optimizes the operation process and convenience, and improves work efficiency.

[0018] like Figure 1-2 As shown, there are four acoustic sensors 12, which are respectively set on the outer side of the four corners of the weighing tray 2 corresponding to the base 1. They emit and receive detection acoustic waves to the outer periphery of the weighing tray 2. By precisely arranging the four acoustic sensors 12 at the four corners of the outer side of the weighing tray 2, a detection field covering the entire scale body without dead zones can be formed. This structure can accurately detect behavior of approaching the scale body from any direction or attempting to step on the base 1. Moreover, the acoustic sensors are less affected by dust and oil, and are more suitable for the complex environment of the kitchen than infrared beams and other methods, with high reliability in preventing cheating.

[0019] The base 1 has multiple wheels 16 at its bottom, which gives this intelligent warehouse scale excellent mobility and makes it easy to move between different work locations such as warehouses and canteens. At the same time, the multiple wheels 16 can be configured as two fixed wheels and two universal wheels with brakes for easy movement and fixed positioning.

[0020] This smart warehouse scale can be equipped with a built-in rechargeable energy storage battery, freeing it from dependence on a fixed power source and increasing the flexibility of its use. In the event of a sudden power outage, it can seamlessly switch to battery power to ensure the continuation of warehouse operations and guarantee that recorded data will not be lost.
