Description

The polyunit of copper sheet clamping steel plate

The utility model relates to a kind of polyunit of copper sheet clamping steel plate, promptly before the operation of making copper clad laminate or multilayer printed circuit board, make copper sheet, steel plate and copper sheet three make the device of the superimposed operation of automation, also promptly at the device of the superimposed copper sheet in the both sides up and down of steel plate for subsequent job.

Copper clad laminate is for making the basic sheet material of multilayer printed circuit board, and when making copper clad laminate or multilayer printed circuit board, be to be blended in an insulation material (making copper clad laminate) or middle accompanying on the insulation material (making multilayer printed circuit board) of internal layer circuit plate by two-layer copper sheet up and down with hot pressing mode; In present operation, as shown in Figure 1, with steel plate 1 is tool (transition apparatus), one steel plate 1 and a copper sheet 2 are set on the hot pressing bed earlier, after on the stacked copper sheet 2 of next material 3 that will insulate (comprising insulation material or interior layer printed circuit board etc.), stacked again " on the steel plate 1; following stacked copper sheet 2 " formed " combination A ", stacked again insulation material 3, the folded again combination A that goes up, insulation material 3, combination A ... operation so successively (about ten layers), a steel plate on after finishing stacked operation, folding, carry out heat pressing operation with hot pressing mode, copper sheet 2 is blended on the insulation material 3, form copper sheet 2, insulation material 3, copper sheet 2 merges all-in-one-piece " combination B ", and steel plate 1 does not then merge mutually with copper sheet 2; After fulfiling assignment, can take off tool (steel plate 1) and copper clad laminate or double team respectively has the multilayer circuit board of internal layer circuit plate (copper sheet 2, insulation material 3, copper sheet 2).Copper clad laminate in deburring, cut the back for the usefulness of making printed circuit board (PCB), multilayer printed circuit board is made for the electronic loop control desk usefulness of computer or communication, tool (steel plate 1) then provides aforementioned and usefulness copper sheet 2 superimposed operations again.

Usually, in heat pressing operation once, can produce ten copper clad laminates or multilayer printed circuit board (i.e. " combination B "); In other words, each heat pressing operation needs ten groups " combination A " approximately, and this combination A is the superimposed operation of the utility model alleged " copper sheet clamping steel plate ".

Plate size in the general copper clad laminate is about wide 80-1100mm, long 1000-1300mm, thick 1.5-2.0mm, and copper sheet then width is bigger, the then about 9-35 μ of thickness m.

In general superimposed operating condition, copper sheet is standby with the reel of whole volume, and steel plate then is to stack standby (disassemble transmission after the pressing operation is finished, heavily cover use) in advance.

The superimposed mode of operation of existing copper sheet clamping steel plate has three kinds:

1. on a fixing superimposed table, after artificial or copper sheet placement of automated manner absorption, inhale a steel plate again and be placed on the copper sheet, and then place a insulation material, put a copper sheet after finishing again on the material that insulate, the superimposed operation of after this putting a steel plate again.

2. on steel plate, put copper sheet, utilize crane with above-mentioned stacked copper sheet and steel plate by bilateral gripping, slinging is placed on the ready copper sheet of side again, finishes superimposed operation.

3. two sub-folders are got rod about utilizing, copper sheet is pulled out up and down simultaneously, steel plate then pushes up and down between the copper sheet from the outside by bilateral support draw runner, when three working substances arrive same upper-lower position, upwards push up by the plane desktop that is arranged on down the copper sheet below, make copper sheet, steel plate and copper sheet can be combined into predetermined closed state.

Above-mentioned three kinds of folding methods are imperfect: if with 1 and 2 mode of operation, dust (waving or dust fall) attached to the contact surface with steel plate of copper sheet up and down, as if being used for circuit board manufacturing, will cause the bad situation of quality easily.

Above-mentioned mode of operation 3 is pulled out steel plate simultaneously because of copper sheet about being and is inserted by the centre, really can avoid steel plate contaminated, but this mode of operation still has its shortcoming:

1. copper sheet is that two gripping rods are pulled out about utilizing up and down, in the time will carrying out next gripping operation again, if when meeting relatively thinner copper sheet (9 μ m), because of copper sheet too soft, making it is that nature is sagging in the guillotine exit, often causes the copper sheet gripping rod leading edge of gripping copper sheet accurately and effectively.

2. pull out up and down and insert a steel plate by the centre behind the copper sheet, it is having a planes carry table below copper sheet down, copper sheet is cut off simultaneously to be released simultaneously to fall with steel plate and is stacked on the carrying table up and down, cause is to fall storing downwards, forming up and down, copper sheet can be drift state all around, three's regularity is not good when superimposed, moreover, when carrying table toward rising, because of desktop must less than steel plate (so desktop just can not hit tight support steel plate about the outside help draw runner) cause down the copper sheet left and right sides partly to have hang in the outside greater than carrying table (copper sheet need be slightly larger than steel plate on the processing procedure) so that about forming, when the past rising of carrying table, the both sides, the outside of following copper sheet promptly are hang, the gripping under the situation that following copper sheet does not shakeout of the bilateral anchor clamps of crane then descends the sagging part in the outside of copper sheet very easily to cause the fold injury.

The purpose of this utility model is to provide a kind of superimposed apparatus for work of improvement, and the shortcoming that above-mentioned three kinds of traditional work modes are produced is improved.
