In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in the drawings, the weighing apparatus of the present utility model comprises: the weighing device comprises a bottom plate 1, a sealing cover 2, a weighing assembly 3 and a cover plate assembly 4, wherein the weighing assembly 3 is arranged on the bottom plate 1, the sealing cover 2 is arranged on the weighing assembly 3 in a covering mode, the sealing cover 2 is provided with a glue inlet 21, the cover plate assembly 4 is arranged on the bottom plate 1, and the cover plate assembly 4 can shield the glue inlet 21 when the weighing assembly 3 weighs. The glue inlet 21 is shielded through the cover plate assembly, so that the tightness of the weighing assembly 3 can be improved during weighing, the influence of an external magnetic field on the weighing assembly 3 is isolated, and the weighing precision is improved.

For example, the weighing assembly 3 comprises: the weighing body 31 and the rubber cup 32, the weighing body 31 is provided with a weighing disc 311, the rubber cup 32 and the weighing disc 311 are both positioned in the sealing cover 2, the rubber cup 32 is arranged on the weighing disc 311, and the rubber cup 32 is positioned under the rubber inlet 21. When the dispensing head is positioned right above the glue inlet 21, glue can be dripped into the glue cup 32 under the action of gravity, and the glue amount of the time is weighed by the weighing disc 311, so that whether the single-time dispensing amount of the dispensing valve meets the requirement can be known.

For example, the cover plate assembly 4 includes: the driving module 41 and the cover plate 42, the cover plate 42 is connected with the output end of the driving module 41. The cover plate 42 includes: the driving module 41 includes a connection portion 421 and a shielding portion 422, one end of the connection portion 421 is connected to an output end of the driving module 41, and the other end of the connection portion 421 is connected to the shielding portion 422.
