Abstract
The invention discloses a coating head, which comprises at least one row of plastic pins within one plane. The plastic pins comprise a fixed pin head portion and a change pin head portion. The plastic pins with hole diameter of O3 are arranged in the fixed pin head portion, the plastic pins are arranged with each other with a central space of O2, and the number of the plastic pins in the fixed pin head portion is O4. The plastic pins with hole diameter of X2 are arranged in the change pin head portion, the plastic pins are arranged with each other with a central space of X1, the number of the plastic pins in the change pin head portion is Y, and the hole diameter, the central space and the number of the plastic pins of the change pin heads can be adjusted. By adjusting the matching of the number, the hole diameter and the central space of pin heads of the change pin heads, adhesive output amount of the change pin heads in two side areas can be relatively reduced, so that adhesive amount coated on two sides of a base material can be reduced, and the phenomenon of adhesive overflow can not appear. Simultaneously, the adhesive output amount of fixed pin heads in the middle area also can ensure normal adhesion.
Description
Technical field
The present invention relates to a kind of annex of coating machine, particularly its dispense tip.
Background technology
Coating machine is a machine of article being implemented the gluing operation, and it is bonding that for example touch-screen carries out glue.Coating machine comprises the dispense tip that can move horizontally, and dispense tip is provided with the coplanar plastic pin of a row.When being coated with operation, dispense tip moves along horizontal substrate with certain speed, simultaneously plastic pin gluing on base material.After head to be coated is covered single gluing stroke, on base material, fit and accomplished bonding operation by convered structure.
The aperture of the plastic pin on the dispense tip of prior art is the unification diameter, and when the coating operation, the amount that each root plastic pin is coated onto the glue on the base material all is unified, occurs the phenomenon of excessive glue so easily in the base material both sides, causes puzzlement to subsequent production.And if the gel quantity of simple all plastic pins of minimizing, base material then appears easily and by the problem of the glue quantity not sufficient between the convered structure again.
