Description
Technical field
The utility model relates to a kind of metal forming cut-off knife dust arrester, is specifically related to a kind of metal forming that can be used for metal-clad foil plate or multilayer printed wiring board and cuts dust arrester.
Background technology
Before copper-clad plate (Copper Clad Laminate) and multilayer printed wiring board (Multi-Layer Printed circuit Board) pressing, usually copper foil cutter is utilized web-like Copper Foil to be cut into the sheet Copper Foil of setting size, be overlying on the skin that bonding sheet or bonding sheet and core material combine, hot-forming through vacuum laminator, the structural representation of guillotine as shown in Figure 1.According to the demand of client, the web-like Copper Foil of electrolysis or calendering formation is also cut into sheet Copper Foil by cutting mechanism by Copper Foil manufacturer sometimes.But, in the process cutting Copper Foil, because of cut-off knife material, edge of a knife wearing and tearing, not contraposition is installed and the reason such as the edge of a knife and Copper Foil friction easily produces the copper scale of graininess and stratiform, the copper wire of fine strip shape.When cutting the metal impurities such as copper scale or copper wire produced in process and being pressed into base material, can cause occurring that probability short in electrical measurement significantly increases between printed wiring board center line-line, hole-hole or line-hole.
In prior art, cut the generation of copper scale and copper wire in process for reducing Copper Foil, the shape of the large multipair cut-off knife of printed wiring board, copper-clad plate and Copper Foil industry, material, life cycle, mounting means and cleaning mode carry out studying and specification.Simultaneously, be brought into during bonding sheet combination or bonding sheet and core material combine for avoiding cutting the copper scale that produces in process and copper wire, press-in base material forms residual copper, part manufacturer increases Roller for sticking dust and transferring roller combination unit after Copper Foil cuts, and carries out cleaning and shifting to the belt or " O type " band carrying Copper Foil.Consider that sheet Copper Foil cannot directly adhere to copper foil surface and be cleaned under being in tension-free state, feasible way is by the belt of clean transport sheet Copper Foil or " O type " band, indirectly will cut in process the copper scale producing, stick to copper foil surface or copper wire is removed.But, meanwhile, if the copper scale of Roller for sticking dust adhesion and impurity fail to move away in time, then there is the possibility of reverse " pollution " Copper Foil of Roller for sticking dust in the mode poor effect that this kind indirectly clean.
Chinese patent Authorization Notice No. CN201140415 discloses a kind of dust collector of electrical condenser aluminum foil cutting machine, electrical condenser aluminum foil cutting machine installs additional a dust arrester, described dust arrester is a vacuum cleaner, described vacuum cleaner comprises dust collector host, cleaner head, tube connector, described cleaner head is made up of shell, air inlet, air channel, air outlet, fixed mount, cleaner head is arranged on the tool axis below cutter shaft by fixed mount, electrical condenser aluminum foil cutting machine is when working operation, and exhausted most dust is got rid of by dust arrester.Chinese patent Authorization Notice No. CN202088235 discloses dust removing device for aluminum foil cutting machine, and it comprises the suction nozzle be arranged on body, and suction nozzle is connected with the inlet scoop of air-introduced machine by airduct, can remove the aluminium powder and aluminium bits that produce when cutting in time.As can be seen here, the dust and break flour that produce in process is cut for metal forming, above two kinds of solutions are the dust arrester installing dust arrester or suction nozzle, tube connector and dust catcher composition on cutting device additional, remove the dust and break flour of cutting and producing in aluminium foil process by the mode of dust suction of fixing a point.But said apparatus cannot be applied to printed wiring board, copper-clad plate and Copper Foil industry, its reason is as follows: 1) dust exhaust apparatus is in opening for a long time, not only not energy-conservation, simultaneously the negative pressure that produces of dust catcher can to Copper Foil especially less than 1 ounce basic weight slim and ultrathin Copper Foil roll out, cut and carry generation harmful effect; 2) the Copper Foil basic weight that printed wiring board, copper-clad plate and Copper Foil industry are conventional is at present between 1/3 ounce to 6 ounces, and above-mentioned dust arrester cannot regulate the pressure producing negative pressure according to the change of Copper Foil basic weight; When negative pressure pressure is excessive, Copper Foil rolls out, cut the dimensional accuracy that location will definitely not have influence on sheet Copper Foil, reduces sheet Copper Foil handling efficiency and even causes the apparent folding line of Copper Foil; When negative pressure too little pressure, upper and lower cut-off knife cuts the copper scale that produces in Copper Foil process and copper wire possibly cannot be adsorbed by dust arrester and remove, and causes occurring increased risk short in the residual copper of base material and multilayer printed wiring board electrical measurement.
