Abstract

The utility model relates to a vacuum adsorption plant used for cutting a printed sheet. The top surface of a loading platform is concavely provided with a flow passage, then a fixture plate is closely locked on the top surface of the loading platform air-tightly with a bolt; a location structure for the limiting of the printed sheet is arranged on the fixture plate, and an air hole communicated with the flow passage runs through the fixture plate; the flow passage is communicated with an air suction conduit of a vacuum pump through which the flow passage is pumped into a vacuum state, so a metal composite printed sheet is actually adsorbed on the fixture plate. Due to the characteristic that the fixture plate can be easily separated from the loading platform, the vacuum adsorption plant of the utility model can realize the location effect of constant manufacture and cutting for different printed sheets only by replacing the corresponding fixture plate, and can widely and elastically provide cutting manufacture for different printed sheets without replacing the loading platform.

Description

Apply to cut the vacuum absorption device of printed circuit board (PCB)

Technical field

The utility model provides a kind of vacuum absorption device, refers in particular to a kind of vacuum absorption device that applies to cut printed circuit board (PCB).

Background technology

See also shown in Fig. 1,2, traditional printing circuit board 10 mainly is the compound one copper layer 12 that approaches on a non-metal base plate 11, these copper layer 12 surface etchings have required layout circuit pattern, in order to constitute nonmetal compound printed circuit board (PCB) 10, make it to have light weight and the low characteristic of cost;

This printed circuit board (PCB) 10 has provided pin-and-hole 13 in two ends, PCB processing special machine 20 then is equipped with on workbench 21 and two pin-and-holes, 13 corresponding latches 22, wherein a latch 22 is subjected to connecting rod 23 controls of oil pressure or air pressure control, and can be along workbench 21 set chutes 24 and spacing moving, in order to strengthen the spacing of two latches 22, in order to do printed circuit board (PCB) 10 is fixed on the workbench 21, so that make the main shaft 25 of PCB processing special machine 20 can carry out cutting operation.

The conventional art that this kind fixed printed circuit board (PCB) 10, it is because the two point-supported modes of employing, so be easy to generate the problem of shake cutter and precision forfeiture, more be unfavorable for cutting off the carrying out of processing, it is applicable to that low intensive non-metal base plate 11 cuttings still may be passable, if applying on the compound printed circuit board (PCB) of all-metal with this technique for fixing generally is to adopt the copper layer of a compound tool layout circuit pattern on the aluminium base and constitute, then there is the problem that to process to produce.

Because the compound printed circuit board (PCB) side of this all-metal is enough to provide the demand of the video-audio data data operation of PDA, mobile phone, the contour function information product of DV now, be with, the compound printed circuit board (PCB) of this all-metal is owing to have high strength and high ductibility, so it can produce great resistance accordingly when cutting is provided, if merely with the technology of above-mentioned 2 support fixation for it, the shake cutter that then can produce, cutter loss greatly reach the quite slow problems of process velocity.Be with, must just serve as appropriate in the mode of vacuum multiple spot absorption for it, this vacuum suction technology is all announcements to some extent of case before TaiWan, China patent announcement I282409, M264800, M266374.. or the like patent.These commonly use structure and can't be economical difformity printed circuit board (PCB) machining extensively is provided, because during a replacing different printing circuit board, then the microscope carrier of this vacuum suction all must be changed, thus, it is the suitable height of cost of mold exchange more, and quite is unfavorable for mold management.

In view of this, the utility model person be develop the utility model with in response to.

Microscope carrier is the heavy leak-proof gasket that is provided with a protuberate outside the runner scope.

Be provided with the tank that can supply cutter to cut off processing in the tool plate, and the pore of tool plate is on average to be located at inside and outside the scope of tank.

The tool plate top surface is concaved with the alignment grooves relative with the complex printed-circuit board shape, and this alignment grooves constitutes the location structure that complex printed-circuit board is spacing.

Adopt above-mentioned structure, the utility model is mainly established a tool plate in the microscope carrier end face lock of a tool runner, the mode that this tool plate is established by lock and reach easy separation and airtight assembling, being concaved with the alignment grooves relative with the complex printed-circuit board shape by this tool plate can locate printed circuit board (PCB), and provide the pore that is communicated with runner, by vavuum pump with the runner state that is evacuated, the metal composite printed circuit board (PCB) can be adsorbed on the tool plate really and bear cutting stress, conveniently carry out machining; As seen the utility model by the tool plate easily clutch in the feature of microscope carrier, need only change corresponding tool plate, the locating effect of different printing circuit board can be provided, be beneficial to the carrying out of machining, have the essence progressive that meets economic manufacturing and easy mold management.

For making your juror can further understand structure of the present utility model, feature and other purpose attachedly now describe in detail as the back with preferred embodiment and accompanying drawing:
