Battery core fluid injection is a procedure essential in battery core manufacture, and fluid injection accuracy of measurement is to weigh filling machine quality again
Key factor, the height of fluid injection accuracy of measurement directly determine the quality of a filling machine.Weighing system is the detection system of fluid injection precision
System, and pressure sensor is the vital part in weighing system, is that the direct of weighing precision takes on part, its precision is very
Height, but it is also very fragile.The corrosion of electrolyte vapors influences very big on the precision of pressure sensor.
The content of the invention
The present invention provides the safeguard structure that a kind of battery weighs pressure sensor,.
In order to solve the above-mentioned technical problem, the technical solution used in the present invention is：
A kind of battery is weighed the safeguard structure of pressure sensor, including mounting box, pressure sensor and PCB, institute
State pressure sensor and PCB is arranged in the mounting box, the PCB connects the pressure sensor；Institute
State and seat of weighing is provided with mounting box, the bottom of the seat of weighing and pressure sensor contacts, and the top of the seat of weighing is dashed forward
For the upper surface of mounting box, when weighing, pressure sensor senses the pressure change for seat of weighing；In the lateral wall of the mounting box
On be provided with gas access port, the gas access port connects with the inner chamber of mounting box, when gas access port access certain flow rate gas
After body, battery electrolyte steam during fluid injection then cannot be introduced into the inner chamber of mounting box.
Further, the gas flow rate of the access port access is 0.005-0.015L/min.
Preferably, the gas flow rate of the access port access is 0.01L/min, while pressure sensor is protected, is prevented
Only pressure sensor induction precision is impacted because air-flow is excessive.
Preferably, the gas of the access port access is nitrogen.
Preferably, the inner chamber of the mounting box is provided with dividing plate, and the inner chamber of the mounting box is split up into isolation by dividing plate
Chamber top and inner chamber bottom, the pressure sensor are arranged on inner chamber top, and the PCB is arranged on inner chamber bottom, institute
