Abstract
The utility model discloses a LED leads frame clamping and conveying mechanism, which comprises a fixed plate and a driving arm connected with a power source. The utility model is characterized in that: a clamp device is arranged between the driving arm and the fixed plate, the device is mainly composed of a fixed claw and a corresponding movable claw, the driving arm is rotatabely connected with the fixed plate. The utility model adopts a pair of claws to clamp stably the lead frame so as to perform feeding movement, and has simple convenient operation and reliable structure, the lead frame is not to generate vibration along the direction vertical with the feeding direction during feeding movement, thereby overcoming the problem that the leads frame dashes forwardly due to the inertia. The utility model has good popularization value.
Description
Technical field
The utility model relates to field of semiconductor manufacture, more particularly relates to a kind of lead frame connecting gear that is used for full-automatic illumination diode (LED) chip bonding machine.
Background technology
Lead frame is a chip bearing support of making light-emitting diode (LED), and the production process chips by the carrying position of weldbonding to lead frame, just can be made various finished product of LED through follow-up operations such as bonding wire, plastic packaging, stamping-out and test one by one again.On full-automatic semiconductor chip bonding machine, lead frame must just can continuously offer chip through step feeding process and implement weldbonding.Index(ing) feed mode commonly used at present has two kinds, a kind of is to drive accurate ball screw rotation by rotating and reverse of servomotor, the feed screw nut is done reciprocating linear motion, on parts moving linearly, collude the retaining part that pawl inserted and withdrawed from lead frame simultaneously by the energising and the outage drive of electromagnet.The feeding requirement that the action of servomotor and electromagnet cooperatively interacts and can finish lead frame.Another kind method is by two disc cams of a driven by motor, and a cam is realized colluding pawl and inserted and withdraw from the lead frame retaining part.Two kinds of methods are all similarly utilized and are colluded the retaining part that pawl inserts lead frame, pull over lead frame to assigned address to direction of feed, realize the feeding requirement.There are two shortcomings in the type of drive of this structure, gap between the guide rail guide plate 1-1 is greater than the width (as shown in Figure 1) of lead frame 1-2, lead frame just will inevitably take place in the way of pulling over along the vibrations perpendicular to direction of feed, to such an extent as to influence the feed accuracy of lead frame; As shown in Figure 2, the hollow out width of retaining part is greater than the cross-sectional width that colludes pawl 1-3, and colludes pawl 1-3 exist identical acceleration acceleration and reduction of speed acceleration simultaneously with lead frame 1-2 in the feeding process.At the latter end in a feeding cycle, collude the speed rapid drawdown of pawl, but the speed of lead frame is fallen slowly (being that the reduction of speed acceleration is less), this with regard to having caused lead frame because inertia and just stopping toward the direction of feed segment distance that readvances has influenced feed accuracy.
Summary of the invention
The purpose of this utility model is exactly a kind of simple in structure, the stable and New LED lead frame clamping delivery mechanism at a high speed that provides for the deficiency that solves prior art.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of New LED lead frame clamping delivery mechanism, the transmission arm that comprises fixed head, connection power source, it is characterized in that: be provided with clamping device between described transmission arm and the fixed head, this device mainly colludes pawl by fixed hook pawl and activity corresponding with it and constitutes, and transmission arm and fixed head are rotationally connected.
As further specifying of such scheme, described fixed hook pawl and activity are colluded pawl and are separately positioned on fixed head and the transmission arm, and the fixed head surface is provided with double-screw bolt, and the middle part of transmission arm is provided with the joint pin that is rotationally connected with this double-screw bolt.
The top of described fixed head is provided with the pillar geometrical clamp, and this pillar geometrical clamp vertical fixing connects as one in fixed head and with it.
Be provided with extension spring between described transmission arm and the pillar geometrical clamp.
The two ends of described transmission arm are respectively equipped with bearing and groove, the end of movable hook is provided with and the corresponding clamping flange of this groove, be provided with screw between movable hook and the transmission arm, activity is colluded pawl and can be moved forward and backward along groove, finely tunes as clamping lead frame degree of tightness.
The described power source that is connected with transmission arm is a cylinder, is provided with bar linkage structure between cylinder and the transmission arm.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopt on transmission arm and fixed head, install respectively one can with the transmission arm rotary moveable collude pawl and one fixing collude pawl, transmission arm and fixed head are rotationally connected, by the cylinder source that is used as power, drivening rod drives the rotating purpose that pawl reaches the clamping lead frame of colluding, make in the motion in a whole feeding cycle, two are colluded pawl all is to clamp lead frame reposefully, prevents that effectively lead frame is along the vibrations perpendicular to direction of feed in the middle of this process.
2, between transmission arm of the present utility model and the pillar geometrical clamp extension spring is set also, make two to collude pawl and clamp lead frame and behind a feeding end cycle, just unclamp, the speed of just treating lead frame is reduced to after zero, two are colluded pawl and just unclamp, and the situation of lead frame inertia preshoot so just can not take place.
