Description

Squeegee device of automatic glue applicator

technical field

The utility model relates to the technical field of a gluing head for supplying hot-melt glue, in particular to a gluing device of an automatic gluing machine.

Background technique

As we all know, hot melt adhesive is a kind of adhesive, which can be used for lamination between various objects. For example, in the production process of solar panels, several solar cells are sandwiched between two glass substrates, and used The hot melt adhesive enables two glass substrates to adhere to each other to form a solar panel.

After the molten hot melt adhesive is coated on the glass substrate through the glue nozzle of the glue applicator, due to the stickiness of the hot melt adhesive itself, the hot melt adhesive will remain on the outer edge of the glue nozzle. When the glue nozzle is to be coated with hot melt adhesive again, the hot melt adhesive remaining on the outer edge of the glue nozzle will be coated on the glass substrate, so that the glue point of the glue nozzle on the glass substrate will be silted up Glue, which in turn causes inconsistent thickness of the glue, so that when the glass substrates are pressed together, there will be a gap, which makes it difficult to fit tightly, and even reduces the bonding yield between the glass substrates.

In order to avoid the occurrence of the above situation, the hot melt glue remaining on the outer edge of the glue nozzle is generally wiped and removed manually, but this is not conducive to improving the overall automation of the glue application operation.

In order to improve the above-mentioned problems, it is known that the Taiwan Patent No. M452451 discloses a gluing head cleaning device for an automatic gluing machine, which uses a squeegee to scrape off the gluing nozzle through contact with the gluing nozzle. Hot melt adhesive residue on the edge.

However, when the above-mentioned device removes the hot melt glue remaining on the outer edge of the glue nozzle, it uses the scraper to scrape off the hot melt glue by moving from one side of the glue nozzle to the other side. The relationship of applying force on one side will cause the hot melt adhesive to accumulate on the other side of the glue nozzle, making it difficult for the squeegee to remove all the hot melt glue remaining on the glue nozzle, which will cause the glue nozzle to drip The phenomenon of glue and wire drawing forces the glue removal effect of the glue nozzle to be poor.

In a further implementation, the squeegee is formed on the top of a frame-shaped plate body, and the frame-shaped plate body forms an accommodating space, which is used to collect the hot melt adhesive scraped off by the squeegee groove . Accordingly, it is beneficial for the operator to remove the hot melt glue scraped off by the glue nozzle.

In a further implementation, the squeegee groove forms a neck at the opposite end of the notch, and extends along the neck to the inside of the squeegee to form a bottom, the groove walls on both sides between the neck and the bottom are parallel to each other, the The glue nozzle is displaced to contact the double-sided groove walls between the neck and the bottom, and the double-sided groove walls scrape off the hot melt glue overflowing to the outer edge of the glue nozzle. According to this, use the glue nozzle to contact the bottom to scrape off the hot melt glue concentrated in the middle of the glue nozzle.

In a further implementation, it also includes a tongue, which is fixed on one side of the gluing table and adjacent to the side of the squeegee. The glue nozzle contacts the tongue through displacement, and the tongue scrapes off the overflow. The hot melt glue flowing to the outer edge of the glue outlet, where the tongue piece is made of elastic piece. Accordingly, the glue nozzle scrapes off the hot melt glue remaining on the outer edge of the glue nozzle through the contact with the tongue.

In a further implementation, the tongue is located on a straight path, and the glue outlet contacts the tongue through displacement, and the tongue scrapes off the hot melt glue overflowing to the outer edge of the glue outlet. According to this, the tongue piece is arranged on the straight path, so that the glue outlet contacts the tongue piece during the movement, and then the hot melt glue remaining on the outer edge of the glue outlet is scraped off.
