Problems solved by technology
This kind of device has a large error when weighing lighter objects, and it is difficult to estimate the error range (or the error range is too large); the load cell installed in this type of device will have zero drift every year, All need annual inspection to correct the zero position and its own accuracy
Even if a pallet scale similar to that used in supermarkets is used as a weighing tool, the perfect combination of static (stable) weighing and weighing process cannot be avoided
These have caused puzzlement to the dynamic (acceleration) weighing measurement of small weight (within two kilograms), high precision (one thousandth), so it is necessary to improve the existing dynamic weighing device

Abstract
The invention relates to a dynamic weighing device, in particular to a manipulator cantilever weighing device, which comprises a vertical rectilinear guide rail, wherein a tensile pressure sensor is arranged at the lower end of the vertical rectilinear guide rail; a sucking disc support is arranged at the lower end of the tensile pressure sensor; the sucking disc support, an air pump, a reversingvalve and a pipeline form an object pickup release mechanism; the tensile pressure sensor is connected with a weighing circuit board; the vertical rectilinear guide rail is matched with a horizontal rectilinear guide rail; the vertical rectilinear guide rail can move side to side along the horizontal rectilinear guide rail; and the tensile pressure sensor, the sucking disc support and an object which is picked up or released by the sucking disc support can move up and down along the vertical rectilinear guide rail. The manipulator cantilever weighing device can combine the conveying process and the weighing process of the object, and not only can save the time, but also can quickly acquire the high-precision (one in a thousand or gram-grade weight precision) weight value of each object. Compared with the conventional belt weigh meter, the manipulator cantilever weighing device has obvious advantage in the aspect of weighing precision.
Description
Manipulator cantilever weighing device technical field The invention relates to a dynamic weighing device, in particular to a manipulator cantilever weighing device. Background technique At present, for the dynamic weighing of objects being transported or transported, the method of conveyor belt and floor scale is mainly used. This kind of device has a large error when weighing lighter objects, and it is difficult to estimate the error range (or the error range is too large); the load cell installed in this type of device will have zero drift every year, All need annual inspection to correct the zero position and its own accuracy. Even if a pallet scale similar to that used in supermarkets is used as a weighing tool, the perfect combination of static (stable) weighing and weighing process cannot be avoided. These have all caused puzzlement to the dynamic (acceleration) weighing measurement of small weight (within two kilograms), high precision (1 / 1000), so it is necessar...
