Abstract
Disclosed is an apparatus for injecting working liquid into a micro-injecting device and a method for injecting the working liquid into the micro-injecting device. A container filled with the working liquid is in a vacuum chamber connected to a vacuum device, a plurality of cartridges having micro-injecting devices are inserted into the container and the working liquid in the container is filled into heating chambers of each micro-injecting device. Accordingly, the total manufacturing processes can be simplified so as to increase a production yield and the total manufacturing time of the products can be reduced.
Claims17
An apparatus for filling a micro-injecting device with working liquid, comprising:
- a vacuum chamber;
- air supply and evacuating means connected to the vacuum chamber for evacuating the vacuum chamber, for controlling the lowered pressure within the vacuum chamber, and for supplying air to the vacuum chamber for relieving the lowered pressure;
- a working liquid container within the vacuum chamber for containing the working liquid;
- and
- a cartridge-receiving container for holding a cartridge with a plurality of micro-injecting devices, said cartridge-receiving container being insertable into the working liquid container.
A method for filling a micro-injecting device with working liquid, comprising the steps of:
- loading a cartridge with the micro-injecting device to be filled with the working liquid, placing the loaded cartridge into a cartridge-receiving container and placing the cartridge-receiving container in a working liquid container;
- filling the working liquid container with working fluid;
- cooling the working liquid container;
- forming a vacuum of predetermined pressure surrounding the working liquid container;
- relieving the vacuum surrounding the working liquid container;
- withdrawing the cartridge-receiving container from the working liquid container;
- and
- sealing the heating chamber of the micro-injecting device.
