Multi-phase glue supply device for rubber coating machine

The invention relates to the technical field of a rubberized head for supplying hot melt adhesive, in particular to a multiphase glue supply device for a rubber coating machine.

It is known that a solar panel is a solar cell in which a plurality of solar cells are interposed between two glass substrates, and a conductive line is connected between the batteries to the side of the glass frame to conduct electric energy collected and converted by the solar cells. In order to prevent liquid (such as water) from penetrating between the two glass substrates, the hot melt adhesive is applied to the periphery of the two glass substrates before the two glass substrates are bonded, so that the two glass substrates are bonded together. It can prevent the penetration of liquid and improve the durable life of the solar panel.

At present, most of the coating operations of hot melt adhesives on glass substrates are carried out by using a rubber coating machine. The more advanced ones are automatic rubber coating machines, which are connected by a conduit through a supply cylinder containing molten hot melt adhesive. A rubber head is applied, and the hot melt adhesive is supplied to the rubberizing head by applying pressure to the rubber cylinder to apply the hot melt adhesive to the glass substrate (or other object to be adhered). Among them, heating and temperature sensing components are usually installed on the rubber supply cylinder, the conduit and the rubber coating head, and the heating material is even coated on the conduit so that the molten hot melt adhesive can not be solidified during the rubber supply process. Melting temperature and glue pressure.

Because the traditional automatic coating machine is more traditionally used, a single rubber-coated head is used to glue a single object one by one, and it is known that the rubber-coated head is assembled on a moving arm capable of performing three-axis displacement, and is soft. The conduit is flexibly coupled to the glue cartridge in a fixed position to form a glue supply end to a glue end (ie, one to one). Therefore, there are two major drawbacks:

1. A glue supply end is provided for the glue supply line of a glued end, and the ability of not continuously coating without stopping is not advantageous for improving the productivity of the automatic coating process.

2. As the rubber supply end of the rubber supply end, the capacity of the hot melt adhesive can be fixed. When the amount of hot melt adhesive in the rubber supply cylinder is exhausted, the glue supply and glue application must be temporarily stopped to facilitate the supply of the rubber cylinder. Refilling the plastic and warming it to form a molten hot melt adhesive has hampered the increase in the yield of automated gumming.

In view of this, one of the aims of the present invention is to improve the configuration of the glue supply line of the plastic applicator end to the glue applicator end, which is not conducive to the problem of improving the automatic gluing yield.

To this end, the present invention provides a multi-phase glue supply device for a rubber applicator, the technical means comprising: at least one glue supply end, a plurality of glue application ends and a mold base, the mold base forming a glue chamber, the glue material The chambers are respectively connected to the glue supply end and the glue application end via a conduit; wherein the glue chamber is also connected with a booster pump of the same number as the glue end.

In further implementation:

The glue supply end is a rubber supply end, and the glue application end is a glue application head. Wherein, the rubberized head frame is assembled on the moving arm of the automatic glue applicator. The glue applicator is used to coat the hot melt adhesive on the periphery of the glass substrate. The plurality of rubber coating heads are distributed in a plurality of rubber coating zone stations for applying glue to the surrounding frame edges of the glass substrates in the respective coating zone stations. The conduit is coated with a thermal insulation material and is wrapped with a heating wire. The booster pump is a gear pump.

The two ends of the adhesive chamber are respectively formed with rubber inlet holes and transmission holes which are equal in number and are connected to each other, and the rubber inlet holes are connected to the glue supply end via the conduits. Wherein, the mold base is formed with a plurality of rubber guide holes connecting the adhesive chambers, the number of the rubber guide holes is equal to the glue coating end, and the rubber guide holes are respectively connected to the glue coating end via the conduits. The booster pump is fixed on the mold base, and the booster pump has a glue inlet hole communicating with the transmission hole and a glue outlet connecting the glue guide hole hole.

The mold base is embedded with a plurality of heating rods, and the heating rods are respectively disposed at the periphery of the plastic chamber. Wherein, the heating rods are respectively disposed around the periphery of the glue inlet, the transmission hole and the glue guide hole.

According to the above technical means, the present invention can realize the supply line of the glue supply end to the plurality of glue coating ends (ie, one-to-many), thereby, in addition to performing any one of the plurality of glue application stations In addition to the separate gluing operation of the station, it is also possible to perform simultaneous gluing operations on a plurality of gluing stations, thereby effectively increasing the productivity of the automatic gluing.

Another object of the present invention is to improve the supply of the conventional glue applicator, and the capacity of the hot melt adhesive is fixed, which causes the glue supply and the glue application to be stopped during the reloading process, thereby hindering the automatic glue application. The problem of yield.

To this end, the multi-phase glue supply device provided by the present invention can also realize a plurality of glue supply ends for a plurality of glue-coated ends (ie, many-to-many) supply line, so as to be used in a plurality of glue supply ends. When one glue end needs to be refilled, the other glue supply end of the plurality of glue supply ends can be fed to the glue end in a timely manner, so as to avoid stopping the glue supply and stopping during the rubber coating process. The phenomenon of gluing and thereby increasing the yield of automated gluing.

A further object of the present invention is to create a design of a plurality of heating rods on a mold base, and a design of a booster pump (gear pump) on the mold base to generate a hot melt adhesive during the transmission of the glue supply line. The function of relay heating and relay pressurization is to maintain the good fluidity of the hot melt adhesive and prevent the hot melt adhesive from solidifying during the glue supply process.
