The present application provides a dimension/weight measuring device 10, which includes a table 11, a stopper 12, a weight sensor (not shown), a first distance sensor 14, a second distance sensor 15, and a third distance sensor 16. The table 11 can carry an article; the limiting part 12 is disposed on the working table 11, and the limiting part 12 can be matched with the article, so that the article is located at a preset position. The weight sensor is provided on the table 11, and the weight sensor can measure the weight of the article. A first distance sensor 14, a second distance sensor 15 and a third distance sensor 16, the first distance sensor 14 being arranged above the table 11, the first distance sensor 14 being adapted to measure a distance to the article in a first direction; a second distance sensor 15 and a third sensor are provided on the table 11, the second distance sensor 15 being for measuring a distance to the article in the second direction, the third distance sensor 16 being for measuring a distance to the article in the third direction; the first direction, the second direction and the third direction are different from each other.
The shape of the article may be a rectangular parallelepiped, a square, or the like, so that the article can be stably placed on the table 11.
Wherein the position limiter 12 is capable of limiting the position of the article so that the article remains relatively stationary with the first distance sensor 14, the second distance sensor 15 and the third distance sensor 16 during the measurement process, thereby increasing the accuracy of the dimension measurement of the article. In the examples of this application, the length of the article in the first direction is taken as height, the length in the second direction is taken as length, and the length in the third direction is taken as width.
It is understood that since the positions of the limiting member 12, the table 11, the first distance sensor 14, the second distance sensor 15, and the third distance sensor 16 are relatively fixed, the distance between the above structures is a fixed value. After the object is engaged with the limiting member 12, for example, the first distance sensor 14 may detect a distance from the object along the first direction, where the distance is recorded as a first distance, and then, according to the known distance between the workbench 11 and the first distance sensor 14, the distance is recorded as a second distance, and the height of the object may be obtained by subtracting the first distance from the second distance; for example, the second distance sensor 15 may detect the distance from the article in the second direction, which is recorded as a third distance, and then, according to the known distance from the workbench 11 to the second distance sensor 15, which is recorded as a fourth distance, the length of the article may be obtained by subtracting the third distance from the fourth distance; for example, the third distance sensor 16 may detect the distance from the article in the third direction, which is denoted as a fifth distance, and then the distance from the table 11 to the third distance sensor 16 is known, which is denoted as a sixth distance, and the length of the article may be calculated by subtracting the fifth distance from the sixth distance. Finally, the volume of the article is calculated from the length, width and height of the article.
The position-limiting member 12 may be a baffle or a mark. When the position-limiting element 12 is a baffle, the position of the object can be limited by the baffle and the workbench 11, and a technician can fix the relative positions of the position-limiting element 12, the workbench 11, the first distance sensor 14, the second distance sensor 15 and the third distance sensor 16 only by moving the object to be matched with the baffle; when the stopper 12 is a mark, a technician can fix the relative positions of the stopper 12, the table 11, the first distance sensor 14, the second distance sensor 15, and the third distance sensor 16 by simply moving the article to a position where the mark is directed.

Therefore, the limiting part 12 is matched with the distance sensors, so that the stability is good and the accuracy is high in the process of measuring the size of the object.
The first direction, the second direction and the third direction are pairwise perpendicular. Because the shape of article often is square and cuboid, when first direction, second direction and third direction are two liang perpendicular, can obtain the length, width and the height of article comparatively conveniently to reduce the calculation volume.
