Technical Field

[0001] This utility model relates to the field of logistics technology, and in particular to an adjustable cargo volume measuring device. Background Technology

[0002] Cargo volume measurement equipment is a key intelligent device in modern logistics, warehousing, and e-commerce. It is mainly used to automatically and efficiently acquire information such as the size, volume, weight, and barcode of goods. Cargo volume measurement is a crucial link in logistics, warehousing, transportation, and trade, directly affecting freight calculation, loading scheme optimization, and warehousing costs. Existing cargo volume measurement equipment requires that the goods be placed in the camera's field of view when placed on the weighing platform. If the camera cannot fully capture the entire surface or outline of the goods, or if the goods are placed crookedly, it will affect the volume measurement results. Therefore, it is usually required that the handling personnel straighten the goods, which reduces the efficiency of cargo handling. Utility Model Content

[0020] Reference Figure 1-2 As shown, an adjustable cargo volume measuring device includes:

[0021] A platform 1 is provided, with a lifting mechanism 2 installed on one edge of the platform 1. Slide rails are provided on both sides of the lifting mechanism 2, and a lead screw is installed in the middle of the lifting mechanism 2. A light shield 3 is slidably mounted on the lifting mechanism 2, and a camera 6 and a distance sensor are installed in the center of the light shield 3. A computer display screen 7 and an electronic scale display 8 are installed on the side of the lifting mechanism 2 closest to the platform 1. A weighing platform 4 is provided above the platform 1, and a positioning mechanism 5 is embedded in the weighing platform 4. A cavity is provided inside the platform 1, which is configured to house the computer. Through the positioning mechanism 5 embedded in the weighing platform 4, the goods can be automatically positioned and calibrated to ensure that the goods are in the optimal shooting area of ​​the camera 6, avoiding the camera 6's inability to fully capture the outline of the goods due to skewed placement, thereby improving the accuracy of volume measurement.

[0022] Furthermore, in order to adjust the distance between the camera and the goods and improve the accuracy of image acquisition and measurement data, a lifting mechanism 2 is provided. Slide rails are provided on both sides of the lifting mechanism 2. A light shield 3 has side sliders on both sides near the lifting mechanism 2. These side sliders are adapted to the slide rails, facilitating the movement of the light shield 3 on the lifting mechanism 2. A lead screw is provided in the middle of the lifting mechanism 2, and auxiliary rods are provided on both sides of the lead screw. The light shield 3 is connected to the lead screw and auxiliary rods on the side near the lifting mechanism 2. One end of the lead screw is connected to a drive motor via a coupling. The drive motor is connected to a computer via a conversion circuit to drive the lead screw of the lifting mechanism 2, thereby driving the lifting and lowering of the light shield 3. By adjusting the distance between the light shield 3 and the weighing platform 4, the light intensity of external light entering the shooting area of ​​the camera 6 is adjusted. A computer display screen 7 and an electronic scale display 8 are installed on the side of the lifting mechanism 2 near the platform 1.

[0023] Inside the light shield 3, in the center, is installed a camera 6 and a distance sensor. The camera 6 is electrically connected to a computer to acquire images of the goods to be measured and send them back to the computer. The distance sensor is also electrically connected to the computer to measure the height of the camera 6 and the height of the camera 6 from the goods to be measured, and send these measurements back to the computer. The computer is connected to the camera 6, the distance sensor, the display, and the conversion circuit. It is used to analyze and calculate the acquired images of the goods to be measured and output the length, width, and height of the goods, as well as control the lifting mechanism 2 to lift. The computer display screen 7 is connected to the computer and is used to display the length, width, and height of the goods to be measured. The electronic scale display 8 is connected to the scale platform 4 and is used to display the weight of the goods to be measured.

[0024] In this embodiment, the camera 6 is mounted on the light shield 3, which allows the camera 6 to be moved up and down, expanding and narrowing the shooting range of a single camera 6, thereby accurately capturing images of goods of different sizes for image processing; at the same time, by setting the light shield 3, it is ensured that the image acquisition process is not easily affected by light factors, resulting in unclear edge contours of the acquired image; the lifting mechanism 2 can automatically lift up and down, which can be specifically controlled by a computer to drive the motor to move up and down.

[0025] As a preferred implementation, a barcode reader for the goods to be tested can also be set up next to camera 6. This camera can collect the barcode of the goods to be tested while capturing the image and weighing them, and send the data back to the computer. The computer can then identify the goods to be tested based on the barcode and display their weight, volume, freight, and serial number on the computer screen, making it convenient for operators to confirm the status of the goods to be tested.

[0026] Furthermore, to ensure the goods are centered within the camera area of ​​camera 6, a positioning mechanism 5 is embedded in the weighing platform 4. The weighing platform 4 has a first and a second sliding groove arranged perpendicularly to each other, with the second sliding groove located below and penetrating the first sliding groove. The positioning mechanism 5 includes a first positioning component 51 and a second positioning component 52. The first positioning component 51 is located in the first sliding groove, and the second positioning component 52 is located in the second sliding groove. The first positioning component 51 is equipped with a first left-right rotating lead screw, with first sliders at both ends of the first left-right rotating lead screw. Each first slider is equipped with a first baffle. One end of the first left-right rotating lead screw is connected to a first... A coupling is provided, with the other end of the first coupling connected to a first motor; a second positioning assembly 52 is provided with a second left-hand and right-hand lead screw, with a second slider at both ends of the second left-hand and right-hand lead screw, and a second baffle on each second slider; one end of the second left-hand and right-hand lead screw is connected to a second coupling, and the other end of the second coupling is connected to a second motor; the first motor and the second motor are electrically connected to a computer and are used to control the rotation of the first left-hand and right-hand lead screws and the second left-hand and right-hand lead screws, so that the first slider and the second slider move closer to the middle position of the weighing platform 4; a weighing sensor is provided on the weighing platform 4, and the weighing sensor is electrically connected to the computer and is used to measure the weight of the goods.

[0027] In this embodiment, the goods to be weighed can be placed on the weighing platform 4 to achieve simultaneous weighing. The weight of the goods is displayed on the electronic scale display 8, which can also feed back the specific weight value to the computer. The computer can display the weight and volume of the goods on the computer display screen 7. At the same time, the pre-set freight calculation system can read the weight and volume of the goods and output the actual freight cost. When the goods are placed on the weighing platform 4, the weighing sensor detects the weight signal and transmits the signal to the computer. After receiving the signal, the computer drives the first motor and the second motor. The first motor drives the first left-hand and right-hand lead screw to rotate through the first coupling, and the second motor drives the second left-hand and right-hand lead screw to rotate through the second linkage. Since the threads at both ends of the first left-hand and right-hand lead screws are in opposite directions... Its rotation causes the first sliders at both ends to move relative to each other along the first slide groove. The first baffles on the first sliders move with the sliders, pushing the goods from both sides until the goods are aligned to the preset center position in the direction of the first slide groove. Similarly, the rotation of the second left and right screws causes the second sliders at both ends to move relative to each other along the second slide groove. The second baffles on the second sliders push the goods from the other sides, aligning the goods to the preset center position in the direction of the second slide groove. When the baffles in both directions have pushed the goods to the center position, the computer receives the relevant positioning signal, which can be achieved, for example, by setting a position sensor on the slider or baffle. The computer then controls the first and second motors to stop working or controls the first and second sliders to return to their original positions. The positioning mechanism completes the positioning and calibration of the goods. At this time, the goods are in the optimal shooting area of ​​the camera.

[0028] Further, the specific embodiments of this utility model are as follows:

[0029] First, adjust the position of camera 6 so that its shooting angle is parallel to the weighing platform 4 to ensure that a top-view image of the goods to be measured can be captured. After the goods to be measured are placed on the weighing platform 4, the computer receives a signal from the weighing sensor and drives the first motor and the second motor to center the goods on the weighing platform 4. The computer uses camera 6 to determine whether the edges of the goods to be measured are all on the image and sends a raising or lowering command to the lifting mechanism 2. The drive motor rotates to raise or lower the light shield 3. The height is transmitted back to the computer through the distance sensor until the edges of the goods to be measured are all on the image. The computer then sends a stop command to the drive motor. The computer analyzes the image captured by camera 3 to obtain information such as the length, width, height and weight of the goods and displays this information on the computer display screen 7.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
