[0002] With the development of society, warehouses are also built in the form of buildings in order to improve space utilization. The application of weighing in warehouses is indispensable. Setting a hidden weighing platform in the floor is a commonly used weighing method. That is, a weighing platform pit is opened on the floor, and the weighing platform is set in the pit. When the carrying robot passes by the weighing platform, it can be weighed through the sensor induction.
[0003] However, due to the limited thickness of the floor slabs on non-ground floors, the weighing platform is also set up with an ultra-thin structure with low strength. When the weighing platform uses sensors for measurement, the weighing platform sometimes shakes back and forth, left and right, and even collides with the inner walls around the pit, thus causing damage to the weighing platform or affecting the accuracy of the weighing platform measurement.

[0033] The following is combined with Figure 1-6 This application is described in further detail.
[0034] The present application embodiment discloses a floor invisible weighing structure. Figure 1 The weighing structure is arranged in the pit 101 of the floor 1, and the weighing structure is flush with the elevation of the floor 1.
[0035] Reference Figure 1 The floor invisible weighing structure includes a table top 2, a plurality of weighing sensors 3, a bracket 4 and a baffle 5.
[0036] Reference Figure 2 and Figure 3 The bracket 4 includes a first bracket 41 and a second bracket 42. The first bracket 41 is fixedly connected to the table 2. The weighing sensor 3 is arranged between the first bracket 41 and the second bracket 42. The first bracket 41 and the second bracket 42 are both provided with a mounting groove for accommodating the weighing sensor 3. The weighing sensor 3 abuts against the first bracket 41. There is a gap between the first bracket 41 and the second bracket 42. The second bracket 42 abuts against the bottom wall of the pit 101. The table 2 is arranged on the first bracket 41, and the table 2 abuts against the first bracket 41. The baffle 5 is arranged on the side of the table 2 close to the first bracket 41. The baffle 5 is fixedly connected to the table 2, and the baffle 5 is arranged around the first bracket 41. The baffle 5 is used to abut against the first bracket 41, so that the first bracket 41 has a limiting effect on the table 2.
[0037] Reference Figure 1 and Figure 2 , the table 2 is flush with the elevation of the floor 1, and the carrying robot carrying the goods moves from the floor 1 to the table 2 of the weighing structure. The weighing sensor 3 sensor can be a strain gauge, a pressure sensor or other types of sensors, which are used to detect the force applied by the carrying robot to the table. The weighing sensor 3 in the weighing structure completes the corresponding data collection to complete the weighing of the goods. In this embodiment, by arranging the weighing sensor 3 between the first bracket 41 and the second bracket 42; it is possible to reduce the influence of the slight shaking tendency of the table 2 on the weighing sensor 3, thereby extending the service life of the weighing sensor 3.
[0038] Reference Figure 1 and Figure 2 The table top 2 includes a steel plate 21 and a plurality of steel bars 22 . The steel bars 22 are fixedly connected to the steel plate 21 , and the steel bars 22 are arranged on a side of the steel plate 21 close to the bracket 4 .
[0039] Reference Figure 2 and Figure 4 , the steel bar 22 includes a first steel bar 221, a second steel bar 222 and a third steel bar 223; the first steel bar 221, the second steel bar 222 and the third steel bar 223 are each provided with a plurality of steel bars. In this embodiment, the first steel bar 221 is arranged perpendicularly to the second steel bar 222, and the first steel bar 221 and the second steel bar 222 are arranged in a grid shape. The third steel bar 223 and the first steel bar 221, the third steel bar 223 and the second steel bar 222 are all arranged in an interlaced manner; that is, the third steel bar 223 is arranged obliquely on the diagonal line of the grid formed by the first steel bar 221 and the second steel bar 222. By arranging a plurality of steel bars 22 at the bottom of the steel plate 21, the structural rigidity of the table top 2 is improved. Specifically, the first steel bar 221 and the second steel bar 222 are arranged in a grid shape, so that the structural rigidity distribution of the table top 2 is more uniform, thereby reducing the situation where the strength of the local area of the table top 2 is low; the interlaced third steel bar 223 further improves the strength of the structure of the table top 2. Therefore, when the robot passes through the table 2 of the weighing structure, the deformation of the table 2 can be reduced, the shaking of the table 2 can be reduced, and the service life of the weighing structure can be extended. At the same time, the weighing sensor 3 arranged between the table 2 and the bracket 4 transmits data information to the background, so that the weight of the goods can be weighed more accurately.
[0040] Reference Figure 5 In addition, the second bracket 42 is provided with a plurality of plug holes 6, and the plug holes 6 are used for inserting and fixing the embedded parts 7 of the floor 1. The embedded parts 7 of the floor 1 are inserted into the plug holes 6 of the bracket 4, so that the embedded parts 7 have a limiting effect on the bracket 4; thereby limiting the shaking of the weighing structure from front to back and from left to right, and reducing the situation where the weighing structure touches the side wall of the pit 101.
[0041] The weighing structure further includes a flexible member 8, which is fixedly connected to the side wall of the plug hole 6, and the flexible member 8 surrounds the embedded member 7, and the flexible member 8 abuts against the embedded member 7. The flexible member 8 can be a flexible material such as a rubber sheet, a silicone sheet, etc. By arranging the flexible member 8 between the side wall of the plug hole 6 and the embedded member 7, the embedded member 7 is flexibly connected to the bracket 4, thereby improving the limiting effect of the embedded member 7 on the weighing structure.
[0042] Example 2
[0043] The difference between this embodiment 2 and embodiment 1 is that:
[0044] When the carrying robot passes through the table 2, a horizontal force will be applied to the weighing structure, so that the upper structure of the weighing structure has a tendency to shake horizontally. Therefore, this embodiment further improves the weighing structure.
[0045] Reference Figure 6 The invisible floor weighing structure also includes a mass block 9 and a plurality of connecting ropes 10; one end of the connecting rope 10 is fixedly connected to the first bracket 41, and the other end of the connecting rope 10 is fixedly connected to the mass block 9; the mass block 9 is suspended between the first bracket 41 and the second bracket 42. By arranging the suspended mass block 9 between the first bracket 41 and the second bracket 42, when the first bracket 41 has a tendency to shake, the suspended mass block 9 plays a damping role.
[0046] That is, the mass block 9 can reduce the horizontal shaking of the first bracket 41 and the shaking of the table 2; thereby reducing the collision damage between the weighing structure and the side wall of the pit 101, and extending the service life of the weighing structure; as well as the influence of the mutual displacement of the first bracket 41 and the second bracket 42 on the weighing sensor 3, thereby extending the service life of the weighing sensor 3.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
