When the mould 22 of injection molding machine 16 is opened (referring to Fig. 1), annular terminal 12 on the either side that is clamped in mould 22 by clamp system 24 and 26 transport substrate 32 and 34 operations by rising/ decline substrate 36 and 38 descend, and when the alignment pin 86 that stretch out the pre-position in the die cavity of mould 22 fits in the corresponding pilot hole 15 of carrier 11, can set the correct insertion position of the terminal board 13 of the annular terminal 12 that will insert.At this, prevent that mistake embedding mould mechanism 40 is programmed to advance to mould 22 to cause horizontal movement substrate 50 by horizontal start cylinder 46 driven plunger 48, thereby the contact member 82 that causes terminal pressure arm 64 front end places be positioned at will embedding mould terminal board 13 directly over, and operation of vertical start cylinder 58 makes terminal pressure head 80 descend to terminal board 13 then.
When the terminal board 13 that will insert aligns correct the realization with the insertion of mould 22, terminal pressure head 80 and terminal pressure arm 64 integrally level and smooth decline and with alignment pin 86 fit engagement, and terminal pressure arm 64 arrives predetermined down location A (being represented by double dot dash line).Therefore, blocked the optical path of optics microsensor 78 with the whole simultaneously check-out console 72 that descends of the substrate 62 that moves both vertically.
When optics microsensor 78 detected the insertion of check-out console 72, it sent signal and comes operation of vertical start cylinder 58, the substrate 62 that moves both vertically is risen to terminal pressure head 80 can not interfere on the height of mould 22; Then, operant level start cylinder 46 retreats horizontal movement substrate 50, and terminal pressure arm 64 moves to initial point B (being represented by double dot dash line) and separates with mould 22 and put aside stand-by.At this moment, injection molding machine 16 carry out to clamp without delay immediately, makes to produce connector end subelement 18 reliably by casting not relating under any problem condition.
On the contrary, when optics microsensor 78 does not detect the insertion of check-out console 72, just judge by program and exist unusual and give the alarm, terminal pressure arm 64 is by returning to initial point B (being represented by double dot dash line) and put aside stand-by with above-mentioned opposite process.Simultaneously, injection molding machine 16 stops to clamp/conveyer 28 and 30 operation.
The operation that prevents mistake embedding mould mechanism 40 of the present invention is according to the operation interlocking ground execution of annular mechanism 10 in microcomputer-controlled program and the mould.Therefore, comprise the operation of annular mechanism 10 in the mould that prevents mistake embedding mould mechanism 40 of the present invention below with reference to the flow chart description of Fig. 4.Begin initial setting up in step 100, and in step 102 substrate 32 and 34 is transported to terminal point b, in step 104, the carrier 11 of annular terminal 12 is fixed by using clamp system 24 and 26 to be pressed in to transport on substrate 32 and 34.In step 106, conveyer 28 and rising/ decline substrate 36 and 38 of 30 are lowered to bottom.In step 108, align with the alignment pin 86 of mould 22 corresponding to predetermined terminal row 13 pilot hole 15, and terminal board 13 fit engagement that will insert have so just been finished initial setting up to the interior pre-position of the die cavity of mould 22.
In step 110, mould 22 rises with conveyer 28 and 30 by known devices, and is press fit on the gate plate (runner plate) 90 with patrix 88, by using mould 22 clampings it and stationary annular terminal 12; In step 112, the resin of supplying with from pre-long-pending ring (pre-plash ring) 92 injects the cavity of the mould 22 that wherein is provided with annular terminal 12 from the nozzle of injection cylinder 94, thus to moulding generation effect.
In step 110, annular terminal 12 is by being fixedly clamped, and in step 118, enters into the stage that clamp system 24 and 26 discharges the carrier 11 of annular terminal 12; In step 120, transport substrate 32 and 34 and move to starting point a, keep clamp system 24 and 26 to be released.In step 122, clamp system 24 and 26 is operated once more, and the carrier 11 of annular terminal 12 is fixed by being pressed in stand-by transporting on substrate 32 and 34.
When in step 114, having finished moulding and passed through suitable curing/cooling cycle, in step 116, open mould 22 by known devices, in step 124, release molded connector end subelement 18 by molded formation; Simultaneously, by clamp system 24 and 26 annular terminal 12 is being fixed on when transporting on substrate 32 and 34, rising/ decline substrate 36 and 38 is risen and annular terminal 12 is clamped on the height that the connector end subelement 18 that forms by embedding mould do not come in contact with mould 22.
In step 126, in the higher position that by rising/ decline substrate 36 and 38 annular terminal 12 is remained in clamp system 24 and 26, move the predetermined stroke S b that reaches home with transporting substrate 32 and 34.In being carried the annular terminal 12 of predetermined stroke S continuously, follow-up terminal board 13 and insertion position coupling, and corresponding pilot hole 15 aligns with the alignment pin 86 of mould 22.In step 128, rising/ decline substrate 36 and 38 drops to extreme lower position and uses clamp system 24 and 26 clampings annular terminal 12 simultaneously, and the terminal board 13 of annular terminal 12 correctly is assemblied in the insertion position of mould 22.
In step 130, by piston 48 operant level start cylinders 46 horizontal movement substrate 50 is advanced from the initial point B that is in dormant state with terminal pressure arm 64, thus make terminal pressure head 80 stop at the inner annular terminals of supplying with continuously 12 of mould 22 carrier 11 directly over.The position of terminal pressure head 80 overlaps with the vertical line of alignment pin 86, and contact member 82 is positioned at directly over the corresponding terminal board 13.In step 132, vertical start cylinder 58 operations and terminal pressure arm 64 begin to descend.When being used to detect the transducer that contacts between contact member 82 and the terminal board 13 not operating in step 134, process turns back to step 134 and continues to descend till detecting contact member 82 and coming in contact with terminal board 13.
In step 136, at A place, predetermined down position, detect contact member 82 and come in contact, so pressure arm 64 stops to descend with terminal board 13.There is time-delay detecting between the time point that time point that contact member 82 contacts with terminal board 13 and terminal pressure arm 64 mechanically stop to descend, this time-delay is exactly electronically controlled like this, simultaneously by be included in contact member 82 in cooperating of elastic buffering mechanism and the microstress or the distortion that produce in the absorbing contact member 82.

Subsequently, thereby the parallel slot 256 with 0.2 millimeter gap K2 is formed with effective length H1 by punching press and forms terminal board 260, and in terminal board, the terminal component 258 with 0.2 millimeter width W is arranged in parallel within the plane with 0.3 millimeter preset space length p2.In addition, with regard to terminal board 260, virtual terminal 250 is cut into length H2 in the position of corresponding length D4, and wherein this length D4 cuts off the end line of the bonding jumper material 242 with high conductivity fully corresponding to eight group of four terminal group 252 to each four terminal group 252.
Before bending, the preparation material 240 that has only shown its part in the drawings is processed into length D4 in stroke, this length D4 equals corresponding to the virtual length towards eight four terminal group 252 of the bending station 241 of pressing machinery, raising that so just can implementation efficiency and the useful life of improving mould.Virtual end plate 250 is irrelevant with length D4, and the above-mentioned like this bending that comprises the terminal board 260 of eight four terminal group 252 just is not subjected to the influence of follow-up preparation material 240, and this subsequent preparation material 240 is adjacent with it and do not experience bending.
The carrier that be used for continuous embedding mould 262 parallel with the carrier 244 of the bonding jumper 242 with high conductivity supplied with off and on to the direction of forward position arrow M2 and the molded cycle synchronisation of injection molding machine.The carrier 264 that constitute the interference fit station, cuts off carriers 244 and virtual terminal 250 corresponding to four terminal group 252 moves to molded carrier 262 (direction of being represented by arrow L) along block 266, up to it till the supporting member 263.Thereby the pilot hole 270 that is arranged on pilot hole 268 in the carrier 244 and molded carrier 262 in advance is in alignment with each other and accurately locatees, and four terminal group 252 are attached on the molded carrier 262 by crimping device 272.
Molded carrier 262 is supplied with four terminal group 252 forward so that they are imported in the embedding mould mould of casting station 273.Thereby the pilot hole 274 of molded carrier 262 engages with respect to mould with the alignment pin 276 of mould (not shown) and accurately locatees four terminal group 252, and this four terminal group is alignd by the pilot hole 270 with 274 one-tenth exact position relations of pilot hole.Then, mould is by known pressure device closure, and connector end subelement 278 is formed by casting.
From above-mentioned explanation as can be seen, in the method that is used for the embedding mould of fine pitch terminal unit of the present invention, product by with the terminal board all-in-one-piece strip carrier of continuous layout forward and intermittent entry make automatically, wherein terminal free ends by virtual terminal clamping so that strengthen terminal, embedding mould passes through to need high-precision process to carry out in small structure portion, this method is applicable to any member like this, in this member, thin member extends from basal component in the pectination mode, realizes that in the middle bending keeps the thin free-ended relative position of member simultaneously.
