[background technology]
Wiring board is to be made of jointly the insulating carrier between multiple layer of copper tinsel cord and the Copper Foil line, and this carrier is exactly a prepreg, just Prepreg film, i.e. PP sheet.In the process of making wiring board, generally need cut prepreg.
See also Fig. 1, prepreg is combined by glass fibre or other fiber 91 and colloid (for example, resin) 92.Cutting mode to prepreg mainly is at present: the prepreg of rolling is positioned on the special equipment, with blade prepreg is cut into certain shape again.In cutting process, shedding (broken rubber powder) and running (filament) phenomenon can appear in the incision site of prepreg.
See also Fig. 2, these sheddings and running tend to be clipped in the wiring board, cause the gap between pcb layer and the layer.When making multilayer circuit board, the connected mode between every layer of wiring board is: boring in the circuit board earlier, electroplate last layer copper at hole wall then, and can realize being electrically connected of Copper Foil of upper and lower layer printed circuit substrate by the copper layer.Under correct situation, Copper Foil 72 and Copper Foil 73 are electrically connected each other, but since the existence of the gap that shedding and/or running caused can't realize being electrically connected between Copper Foil 71 and the Copper Foil 72.
The method that solves at present shedding and running is that the prepreg with well cutting is stacked together, and blows clean with air pressure gun earlier, uses a special infrared edge banding machine again, gives the heating edge sealing of cutting edge.Because in the whole process of cutting, there are shedding and running phenomenon in the capital, when cleaning with the air pressure gun blowing, the one, some more hidden place may blow less than, the 2nd, in the process of blowing, dust can spread in the air, might cause the secondary pollution to prepreg again attached on the prepreg.Before edge sealing, promptly use air pressure gun to blow clean, powder also all has the possibility that comes off at any time, in case in the interlayer of powder and/or silk entry-line plate, will certainly cause wiring board to scrap.And, when carrying out edge sealing, stacking of wiring board to be had relatively high expectations, it is neat that want on the limit that stacks, otherwise the limit of stretching outside is burned, and inside the limit of contracting is roasting less than, the requirement that does not reach whole edge sealing.In addition, when utilizing infrared ray that the prepreg that stacks is carried out edge sealing, be easy to if separate by force, can cause the became uneven at edge to gluing between the layer of prepreg and the layer together.
This shows that the method that solves shedding and running has at present not only increased an equipment, and operating process is loaded down with trivial details, causes the increase of production cost.Along with improving constantly of the precision of wiring board, density, the number of plies, the problem that solves shedding and running seems more and more urgent.
[summary of the invention]
In order to solve in the prior art because prepreg adopts blade cuts can produce shedding and running phenomenon, cause needs to increase follow-up edge sealing operation and edge sealing equipment, the technical problem that causes production cost to increase, the utility model provide a kind of and can cut simultaneously and the prepreg cutting equipment of edge sealing.

[specific embodiment]
By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, below in conjunction with embodiment and cooperate graphic detailed description the in detail.
See also Fig. 3, first preferred implementation of the present utility model, the feed mechanism 3 that this prepreg cutting equipment comprises mainframe 2, is arranged on the workbench 1 on the mainframe 2 and is arranged on workbench 1 upstream.Workbench 1, mainframe 2, feed mechanism 3 connect the formation integral structure.
The prepreg transmission mechanism is housed on the mainframe 2.In the present embodiment, the prepreg transmission mechanism is the roller transmission mechanism that is arranged on workbench 1 at least one side, this roller transmission mechanism comprises: active contact roller 23, be positioned at the driven contact roller 22 of described active contact roller 23 tops, and the pressure regulating mechanism 21 that is used to regulate the relative pressure between described active contact roller 23 and the driven contact roller 22.Initiatively pinch rollers 23 links to each other with servomotor by belt or similar transmission mechanism.
In the material loading process of prepreg, at first semi-solid preparation sheet stock volume 4 is contained on the material loading axle 30, the relaying roller 31 on the prepreg process feed mechanism 3 and the movable rotation-shaft 323 of diastole governor motion 32 are sent to the roller transmission mechanism on the mainframe 2, guarantee the timely supply of prepreg thus.
By the pressure that pressure regulating mechanism 21 is regulated between active contact roller 23 and the driven contact roller 22, make initiatively to produce enough frictional force between contact roller 23, driven contact roller 22 and the prepreg.Initiatively the pressure between contact roller 23 and the driven contact roller 22 can also limit swinging of prepreg, so that realize the stable feeding of prepreg under the drive of active contact roller 23.Prepreg arrives the cutting position of workbench 1 in transport process, the cutting light beam of being exported by cutting head 12 vertically cuts.The prepreg material that downcuts drops on above the cutting agency (figure does not show).Cutting agency can move relative to mainframe 2, so that the prepreg material that cuts is transported.
Further show as Fig. 4 and Fig. 5, cutting head 12 inside are provided with inner chamber 121, be provided with focus lamp 122 in the inner chamber 121, through focusing on the cutting position of workbench 1 after the focusing of focus lamp 122, the prepreg to process cuts thus through suitable guide mechanism or the laser that is directly inputted to cutting head 12.Side at the inner chamber 121 of cutting head 12 is provided with gas blow pipe 123, and gas blow pipe 123 is between the laser beam outlet of focus lamp 122 and cutting head 12.This gas blow pipe 123 is connected with air compression plant (figure does not show).The purge gas circulation that air compression plant produces is crossed the focus that gas blow pipe 123 blows to the laser beam of cutting head 12, just the otch of prepreg.Also be provided with the size that barometric damper 124 is used for regulating air-flow on the gas blow pipe 123.Because gas blow pipe 123 is between the laser beam outlet of focus lamp 122 and cutting head 12, after the purge gas circulation that air compression plant produces is crossed the inner chamber 121 that gas blow pipe 123 is blown into cutting head 12, can only flow to the position of the laser beam outlet of cutting head 12, because the high pressure effect of this air-flow, the dust that makes the incision of prepreg produce can not enter the inner chamber 121 of cutting head 12 against the flow direction of high pressure draught, thereby has guaranteed that focus lamp 122 can be not contaminated.In addition, air compression plant can also be arranged on other position of workbench 1 in other suitable mode, so that flue dust, carbon black that incision is produced purge.

When prepreg is cut into rectangle, the position and the spacing of cutting head 12 can be set according to the width of the raw-material width of prepreg and required prepreg.Because a plurality of cutting heads 12 are worked simultaneously, thereby have guaranteed to have higher efficient when cutting in a large number.
In sum, adopt prepreg cutting equipment of the present utility model when prepreg is carried out cutting processing,, and thoroughly stop otch shedding and running because the laser beam high temperature action makes the prepreg otch seal up the limit automatically.In addition, because laser beam is very thin, concentration of energy is very little to the destruction around the prepreg otch.
In addition, adopt described feed mechanism 3, can effectively guarantee the stable supply timely of prepreg.
Owing to adopt air compression plant, when laser beam cut, the purging air-flow that this device produces rushed at the otch of prepreg, this air-flow can make the prepreg otch in the moment of leaving laser beam, cooled off rapidly by high temperature, this process is quenched exposed glass fiber, becomes fragile.Then, the glass fiber fracture that utilizes the strength that is produced of air-flow to make to become fragile also comes off, and reaches the reinforcement centrifugation.In addition, air-flow blows the resin of incision hot melt off, prevents adhesion again after its cooling, and air-flow can also prevent that prepreg from burning in laser beam, otch is become greatly.
When laser beam cut, dust exhaust apparatus 13 can siphon away flue dust, the carbon black of otch, avoids polluting prepreg, simultaneously, does not also pollute the environment.In addition, the negative pressure that suction port 131 produces can be fixed in prepreg the position of suction port in the transverse cuts process, can guarantee that the prepreg position can not change and be convenient to the focus of laser beam is fixed in the cutting position of prepreg when cutting.
