Profit limit dipping method and device are produced in copper-clad plate
Technical field
The present invention relates to a kind of copper-clad plate and produce dipping method, be specifically related to a kind of copper-clad plate base material production profit limit dipping method and process units thereof.
Background technology
Copper-clad plate is with the substrate impregnation of copper-clad plate in manufacturing process, along its length substrate is cut to certain width then, again at its surface recombination Copper Foil.Before the present invention makes, during copper-clad plate substrate impregnation, be after the substrate of copper-clad plate is covered through the glue spreader one-sided precoat, to get into the glue groove through the carry-over pinch rolls group again, it is immersed in the glue fully.Do like this and make the discarded edge that is cut also soak into glue fully; Make the consumption of glue increase, and because the price of the glue that uses is higher, thereby make production cost raise; And because the discarded edge impregnation that cuts has glue; Its subsequent treatment is utilized difficulty again, increases waste pollution, not environmental protection easily.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide the copper-clad plate that a kind of glue consumption is few, cost is low to produce profit limit dipping method and device.
The objective of the invention is to realize like this: profit limit dipping method is produced in a kind of copper-clad plate; Said method is before copper-clad plate base material entering glue spreader one-sided precoat covers; Copper-clad plate base material dual-side is along its length used water-wet; Cover through the glue spreader one-sided precoat then, through the traction of carry-over pinch rolls group, the copper-clad plate base material is immersed in the glue fully again.
The water of said wetting usefulness linearly current shape flow on the copper-clad plate base material.
Profit limit gumming device is produced in a kind of copper-clad plate; It comprises glue spreader, the first glue groove, carry-over pinch rolls group and the second glue groove; The place ahead of said glue spreader also is provided with filler pipe, and said filler pipe is two, and said two filler pipes are arranged at copper-clad plate base material dual-side top along its length respectively.
Said filler pipe mouth of pipe bottom is horizontal plane.
Said filler pipe mouth of pipe bottom is 5-15mm with the distance of copper-clad plate base material.
The diameter of the mouth of pipe of said filler pipe bottom is 0.5-1.5mm, and said filler pipe nozzle diameter is that the length of 0.5-1.5mm part is 100-150mm.
The invention has the beneficial effects as follows:
Profit limit dipping method and device are produced in copper-clad plate of the present invention, before gluing, adopt water that the edge that the copper-clad plate base material need cut is wetting earlier, and adopt the wetting mode of current; Make the suction of its edge evenly and be prone to reach capacity, in follow-up gluing and immersing glue process, at the absorption glue; The less use amount of glue, thus the production cost rising reduced, and because the discarded edge that cuts does not have glue; Its subsequent treatment is easy with utilization, can not increase waste pollution, environmental protection.

The specific embodiment
Profit limit dipping method is produced in the copper-clad plate that the present invention relates to; Be before copper-clad plate base material entering glue spreader one-sided precoat covers; Copper-clad plate base material dual-side is along its length used water-wet; Cover through the glue spreader one-sided precoat then, through the traction of carry-over pinch rolls group, the copper-clad plate base material is immersed in the glue fully again.
The water of said wetting usefulness linearly current shape flow on the copper-clad plate base material.
Referring to Fig. 1 and Fig. 2, profit limit gumming device is produced in copper-clad plate of the present invention, and it mainly is made up of filler pipe 1, glue spreader 2, the first glue groove 3, carry-over pinch rolls group 4 and the second glue groove 5; Said filler pipe 1 is positioned at the place ahead of glue spreader 2; Said filler pipe 1 is two, and two filler pipes 1 are arranged at copper-clad plate base material 6 dual-side top along its length respectively, and said glue spreader 2 belows are provided with the first glue groove 3; The lower submerged of said glue spreader 2 is in the glue of the first glue groove 3; The said second glue groove 5 is arranged at the rear of the first glue groove 3, and device has carry-over pinch rolls group 4 on the said second glue groove 5, and the part carry-over pinch rolls are immersed in the glue of the second glue groove 5 fully in the said carry-over pinch rolls group 4.
Be the linearly current shape outflow of water that guarantees wetting usefulness, said filler pipe 1 mouth of pipe bottom is horizontal plane, no inclination angle, thus can not produce the phenomenon of condensing water droplet.
In order to guarantee wetting effect and wetting width, said filler pipe 1 mouth of pipe bottom is 5-15mm with the distance of copper-clad plate base material 6.
The diameter of the mouth of pipe of said filler pipe 1 bottom is 0.5-1.5mm, and said filler pipe 1 nozzle diameter is that the length of 0.5-1.5mm part is 100-150mm.
Above-mentioned filler pipe 1 also can be two groups, and said two groups of filler pipes 1 are arranged at copper-clad plate base material 6 dual-side top along its length respectively.
