Therefore, a weighing assembly is required to test and weigh the glue output per single time of the dispensing head.

[0003] A conventional weighing assembly generally includes a sealed base, a weighing device and a sealed cover plate. The weighing device is placed on the sealed base, and the sealed cover plate is driven to seal the sealed base. After the sealed cover plate covers the sealed base, there will be a certain gap between the sealed cover plate and the sealed base, which makes it easy for external water vapor, dust, etc. to enter the weighing environment, thus affecting the weighing work of the weighing device and further resulting in the technical problem of inaccurate weighing.
