Abstract
A glue dispensing system and the glue supplying method thereof are disclosed. The glue dispensing system uses at least one feed tank to provide or supply the glue to a glue dispensing needle cylinder. Thus, the glue dispensing needle cylinder does not need to be replaced or the frequency of replacing the glue dispensing needle cylinder can be decreased in order to save more time, reduce manpower waste and decrease the cost.
Claims20
A glue dispensing system, comprising:
- a first feed tank, coupled to a control valve;
- a second feed tank, coupled to the control valve;
- a glue dispensing needle cylinder, coupled to the control valve, wherein one end of the glue dispensing needle cylinder comprises a glue dispensing valve;
- a first fluid level detecting unit, disposed on the glue dispensing needle cylinder and configured to detect a position of a fluid level of a glue inside the glue dispensing needle cylinder;
- a second fluid level detecting unit, disposed on the first feed tank and configured to detect a position of a fluid level of a glue inside the first feed tank;
- and
- a third fluid level detecting unit, disposed on the second feed tank and configured to detect a position of a fluid level of a glue inside the second feed tank.

A glue supplying method, comprising:
- providing a glue dispensing system, the glue dispensing system including (i) a glue dispensing needle cylinder coupled to a control valve, (ii) a first feed tank coupled to the control valve, (iii) a second feed tank coupled to the control valve, (iv) a first fluid level detecting unit configured to detect a position of a fluid level of a glue inside the glue dispensing needle cylinder, (v) a second fluid level detecting unit configured to detect a position of a fluid level of a glue inside the first feed tank, and (vi) a third fluid level detecting unit configured to detect a position of a fluid level of a glue inside the second feed tank;
- detecting the position of the fluid level of the glue inside the glue dispensing needle cylinder using the first fluid level detecting unit;
- supplying glue to the glue dispensing needle cylinder from the first feed tank via the control valve to increase the glue inside the glue dispensing needle cylinder when the position of the fluid level of the glue inside the glue dispensing needle cylinder is lower than a predetermined position;
- and
- supplying glue to the glue dispensing needle cylinder from the second feed tank via the control valve to increase the glue inside the glue dispensing needle cylinder when the second fluid level detecting unit detects the position of the fluid level of the glue inside the first feed tank is lower than a predetermined position.
