The glue supply pipe connected with the glue supply mechanism 1 is fixed on the guide rod 62 and the spring balancer 52 in sequence.

[0039] Considering that the glue injection head 2 moves in three axes, the glue supply pipe needs to move synchronously, if the glue supply pipe moves poorly, it may cause the separation of the glue supply pipe and the glue injection head 2, affecting the glue injection, or cause the dragging of the glue supply pipe, affecting the service life of the glue supply pipe.
