Be provided with the baffle plate 508 that highly is not more than lamp card base plate thickness X in slider top; Baffle plate 508 is in the lead bottom and perpendicular to lead.Being provided with the lead in slider top is that the distance of 517 of 517, two guide plates of symmetrically arranged two guide plates of symmetry axis equals lamp card width.The base plate front end face that is stuck in the lamp card on the lead contacts with baffle plate 508, the base plate two sides of lamp card contact with two guide plates 517 respectively, that is to say, the lamp card is positioned in baffle plate 508, the two lamp card locating slots that guide plate 517 is surrounded, at this moment, lamp card 2 is relative with the lamp body 3 that is arranged on the pressure head on its top.
Two chelas 512 respectively comprise two sections; The lower end of the hypomere 5121 of two chelas is hinged on the both sides of slide block respectively by pin 506; The hypomere of two chelas extends along the inwall of V-arrangement slideway; The epimere 5122 of two chelas is extended to the both sides of lamp card 2 by the slider top both sides.
In order to adjust the size of (being jaw) between two relative chela epimeres 5122, be provided with and its jaw that becomes to be threaded adjustment bolt 516 in V-arrangement slideway both sides, between the top of jaw adjustment bolt and the hypomere of chela ball 515 is set.When pivoted jaw is adjusted bolt, jaw is adjusted bolt promptly promotes two chelas by ball 515 hypomere, makes the hypomere of chela swing around the hinged jointed shaft of itself and slide block, like this, jaw size between two chelas can change, to adapt to the lamp card of different in width.
When pressure head moves down, the pin of lamp body 3 pierces through the lead skin and extend in the wire stylet, and slide block moves down then, and the hypomere 5121 of two chelas moves under ball 515 effects in opposite directions, make the epimere of two chelas promote the both sides of lamp card, make the both sides card base of lamp card fasten the lamp body both sides.
The pretightning force of elastic filler pierces through the lead skin and extend into the needed power of wire stylet greater than pin, so that pin pierces through the lead skin and extend into before the wire stylet, slide block can not move down.If the pretightning force of elastic filler is too small, when pressure head drive lamp body pressed down, lamp body meeting and lead, lamp card, slide block moved down together, and when the both sides card base that causes two chelas to promote the lamp cards moved inward, pin did not also pierce through the lead skin and extend into wire stylet.
When being provided with between two chela hypomeres 5121, make the back-moving spring 514 that two chelas are separated in normality.When moving on the pressure head, slide block moves up under the effect of elastic filler automatically, and back-moving spring makes two chelas separate, and the hypomere of two chelas is in ball 515 contacted states all the time, for pressing down next time got ready.
Winding mechanism spur at every turn length L that the lead straight line moves greater than between the lamp card on baffle plate and the lamp Kato plate apart from S; When winding mechanism pulling lead moves, be stuck in the lamp card on lead owing to stopped that by baffle plate the lamp card can not move with lead.
After the lamp card was stuck on the lead, winding mechanism pulling lead moved, guarantee the lamp card move to (being provided with on the pressure head) lamp body under after stop to move, like this, pressure head could drive lamp body and press down, lamp body could match with the lamp card.When the lamp card moves if cross lamp body under or do not arrive lamp body under, lamp body all can not press down.The present invention adopt structures such as baffle plate guaranteed the lamp card move to lamp body under after stop to move.Its principle is: we know that after the lamp card was stuck on the lead, the lamp card was also little to the clamping force of lead, and under certain external force effect, the lamp card still can move with respect to the length direction of lead along lead.Distance between the lamp card on baffle plate and the lamp Kato plate is S, and after the lamp card on the plate such as Kato such as lamp such as grade was stuck on the lead, the distance of this lamp card and baffle plate was S.Then, the winding mechanism action, the reach of drive lead, because winding mechanism spurs length L that the lead straight line moves greater than S at every turn, this lamp is stuck in being stopped (distance that baffle plate moves can only be S) by baffle plate in the lead reach process, but this moment, winding mechanism was still at the pulling lead, so lead just continues to stop after reach (L-S) length with respect to the lamp card again.Baffle plate guaranteed on the conductor length direction, lamp be stuck in lamp body under.
Being provided with the lead in slider top is symmetrically arranged two guide plates of symmetry axis, and the distance between two guide plates equals lamp card width.Like this, be stuck in lamp card on the lead with lead when mobile, the lamp card just enters between two guide plates, and two guide plates just move the lamp card and play guide effect, makes the lamp card can not depart from the lamp body on the pressure head on perpendicular to the conductor length direction.
After lamp body and lamp buckle closed, the lamp body and the lamp card that need pulling to snap together moved with lead so that the next lamp card that is stuck on the lead moves under the lamp body that is provided with on the pressure head, for follow-up boths' fastening ready.If be provided with baffle plate, after lamp body and lamp buckle closed, lamp card in lamp body that snaps together and the lamp card was owing to stopped that by baffle plate if the pulling lead, lamp card (with the lamp body that snaps together with it) just can not move with lead.For this reason, along the lead moving direction, be provided with lead ejecting mechanism 509 moving up and down in the place ahead of slide block.Referring to Fig. 2, the lead ejecting mechanism comprises upper roller 5091 and the bottom roller 5092 that is arranged on the push rod 5093, and lead 1 passes between upper roller, bottom roller; When push rod 5093 moves up, bottom roller drives on the lead and moves, be stuck on the lead the lamp card with on move and make lamp card base plate bottom surface exceed baffle plate 508, baffle plate can not keep off on the direction of advance of lamp card again, like this, during the pulling lead, lamp body that snaps together and lamp card will be crossed baffle plate from the baffle plate top and move forward with lead.Certainly, after the lamp body that snaps together and lamp card are crossed baffle plate from the baffle plate top, push rod 5093 will move down rapidly, upper roller presses down lead, so that the next lamp card base plate that is stuck in the lamp card on the lead does not exceed baffle plate, make baffle plate play barrier effect once more to it, guarantee this lamp be stuck in lamp body under stop and do not move with lead.The moving up and down of push rod 5093 can get dead electricity by electromagnet and control.
The course of work: when the lead feeding, conductor strip the lamp card that is stuck on the lead and is moved to the left to lamp body and the equipped center (moving up and down on the center line of pressure head) of putting of lamp block simultaneously, the lamp card is positioned in baffle plate, in the lamp card locating slot that two guide plates 517 are surrounded, lead move on (about 5 millimeter), lamp was stuck in and kept motionless under the baffle effect this moment, make lead with respect to the slippage of lamp card, purpose is in order to eliminate the feeding error of mechanisms such as winding mechanism, make each lead feeding, the lamp card can both be positioned at lamp body and the equipped center of putting of lamp block.
It is descending that the pressure head band lamp body, and the pin of lamp body bottom penetrates conductor center (this moment, the air inlet of pressure head valve no longer held lamp body) after puncturing insulating layer of conductor, and this moment, slide block 505 kept motionless under effect under the precompression of elastic filler; After the lamp body legs and feet all penetrated the conductor center, the downward active force of pressure head can increase, and greater than the pretightning force of elastic filler, it is descending that slide block overcomes the pretightning force of elastic filler, drove integral body such as jaw, lamp card, lead and moved down (micro-stroke, about 1-2 millimeter); The chela epimere shrinks at the effect lower jaw of ball 515, and the chela epimere promotes the lamp card and tightens up, and makes lamp card seam fastening lamp body panel, finishes assembling.
Pressure head is up under main stepper motor drives, and slide block resets under the elastic recovery motive force of elastic filler, and jaw also resets under back-moving spring 514 promotes.
Electromagnet in the lead ejecting mechanism 509 gets electric, and push rod moves up, and lead and the lamp card just loaded onto are upwards pushed away, and exceeds baffle plate; The winding mechanism motion, lead is feeding left; This moment the lead ejecting mechanism the electromagnet dead electricity, push rod moves down and resets, and lead is depressed, and lamp is positioned in the lamp card locating slot that baffle plate, location-plate surround; Winding mechanism continues motion, and the lamp card is stopped by baffle plate, is positioned at that lamp body and lamp block are equipped puts the center, and lead moves on, with elimination feeding error.
The pressure head action is being with another lamp body descending, enters next actuation cycle.
This lamp body and lamp block are equipped puts the relative position relation that has guaranteed between lamp body, lamp card, lead, and after having realized the lamp body pin is pressed into electric wire, the lamp card tightens the pcb board of lamp body automatically, and it is simple in structure, can enhance productivity the rate of reducing the number of rejects and seconds.
