Abstract
The utility model relates to an edge material cutting device of a prepreg, comprising a cutter and a transfer roll for transferring the prepreg, and also comprising a first heating device and a second heating device, wherein the first heating device and the second heating device are respectively arranged at the two sides of the cutter; the first heating device is used for heating the edges of the prepreg before cutting; and the second heating device is used for heating the edges of the prepreg after the edges of the prepreg are cut. In the edge material cutting device, the front and the back of the cutter are respectively and additionally provided with one heating device, so that resin dust generated by cutting is greatly reduced, and large amount of resin dust can not be generated on the edges of a cut prepreg product.
Description
Technical field
The utility model relates to a kind of copper clad laminate process equipment, relates in particular to a kind of rim charge cutter sweep of prepreg.
Background technology
Pcb board is printed circuit board (PCB) just, claims printed circuit board, printed substrate again, is the important electron parts, is the carrier that electronic devices and components are electrically connected.
Copper-clad laminate (abbreviation copper-clad plate) is a baseplate material of making printed circuit board (PCB), and copper-clad laminate is made the printed circuit board (PCB) that needs after through etching, plating, multi-layer sheet pressing.Need to make glass fabric process epoxy resin mixed liquor (promptly containing immersion liquid) in the production process of copper-clad plate and make its surperficial impregnation last layer epoxy resin form prepreg, then through super-dry and rim charge cutting, prepreg after by cutting machine dry and rim charge being cut again cuts into the backing material plate of same size, and backing material plate is put into press pressurized, heated processing formation copper-clad plate after laminating and cover Copper Foil.
At present, carry out in the step of cutting at the rim charge to prepreg, the product edge after the cutting tends to residual more toner, can not satisfy the production requirement of back workshop section.Also there are a large amount of toners to adhere to around the cutting knife simultaneously, influence cut quality.
The utility model content
The above-mentioned defective that exists in view of prior art, when the purpose of this utility model is a kind of the cutting is provided product edge can the cull powder and cutting knife around also can not adhere to the rim charge cutter sweep of the prepreg of toner.
To achieve these goals, the rim charge cutter sweep of a kind of prepreg that embodiment of the present utility model provides, comprise cutting knife and be used to transmit the transfer roller of prepreg, also comprise being divided into second heater that described cutting knife both sides are used for before cutting first heater that heats at the edge to described prepreg and are used in the rim charge cutting back of described prepreg the edge of described prepreg being heated.
As preferably, described first heater and/or described second heater are for by sending the heater that warm braw heats the edge of described prepreg.
Be compared to prior art, the beneficial effects of the utility model are that except significantly improving the adhesion condition of cutter toner, more important is to have reduced the situation that the product edge toner adheres to, and is beneficial to following process by increasing heater.
Description of drawings
Fig. 1 is the structural representation sketch of rim charge cutter sweep of the prepreg of an embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As shown in Figure 1, the rim charge cutter sweep of a kind of prepreg that the utility model provides, comprise cutting knife 4,5 and be used to transmit the transfer roller 2,3 of prepreg 1, also comprise being divided into second heater 6 that described cutting knife 4,5 both sides are used for before cutting first heater 7 that heats at the edge to described prepreg 1 and are used in the rim charge cutting back of described prepreg 1 edge of described prepreg 1 being heated.
As shown in Figure 1, the prepreg 1 dry back through impregnation is driven successively by first heater 7, cutting knife 4,5 and second heater 6 by transfer roller 2,3.Can guarantee that like this prepreg 1 can heat by the edge of 7 pairs of prepregs 1 of described first heater before cutting rim charge by described cutting knife 4,5, the toner that has produced when having reduced cutting.And can heat by the edges of 6 pairs of second heaters prepreg 1 after through cutting knife 4,5 cutting rim charges again, further reduce the adhering to of toner of product side cut place, be convenient to the next procedure production and processing.
In the utility model, reduce the generation of resin dust or adhere to thereby the effect of described first heater 7 and described second heater 6 is cut edge by preheating prepreg 1.Therefore, the kind of heater, heating power etc. can be selected flexibly according to actual production.In the present embodiment, as preferably, described first heater 7 and/or described second heater 6 are for by sending the heater that warm braw heats the edge of described prepreg 1.And, if adopt the mode of warm braw heating, the distance between air output, air outlet and the product of described first heater 7 and described second heater 6 and the product of different-thickness institute design temperature accordingly all need be according to actual production conditions adjustment flexibly.
Claims (2)
1. the rim charge cutter sweep of a prepreg, comprise cutting knife and the transfer roller that is used to transmit prepreg, it is characterized in that, also comprise being divided into second heater that described cutting knife both sides are used for before cutting first heater that heats at the edge to described prepreg and are used in the rim charge cutting back of described prepreg the edge of described prepreg being heated.
2. the rim charge cutter sweep of prepreg as claimed in claim 1 is characterized in that, described first heater and/or described second heater are by sending the heater that warm braw heats the edge of described prepreg.
