In its natural state, the filling head positioning block and / or the sliding base of the positioning block are in contact with the lower limit component. The filling head assembly is then inserted and fixed into the filling head mounting slot of the filling head fixing block, ensuring that the filling (needle) head passes through the filling head positioning slot and enters the contour positioning slot. The filling head is then manually or mechanically grasped. The syringe (with the pusher already installed) to be filled is placed in the contour positioning groove of the syringe positioning seat. Then, the syringe is pushed upward to move the filling head positioning block upward to the filling position where it contacts the upper limit component. At this time, the filling (needle) head gradually extends into the syringe. When the position sensor detects that the filling head positioning block has reached the filling position, the filling machine turns on to fill the syringe. When the filling is completed, the alarm sounds with sound and light. The manual or robotic arm moves the syringe down, and the filling head positioning block moves downward to contact the lower limit component, so that the filling (needle) head disengages from the syringe and the syringe is removed to complete the filling.

[0035] The beneficial effects of this utility model of a semi-automatic filling fixture for syringes are: it can effectively improve the accuracy and stability of filling, thereby improving the efficiency and quality of filling syringe products, and it can adapt to different usage needs. It has a simple structure and is easy to operate.
