Description

The automatic bender of the lead frame of IC punching formation equipment
Technical field
The utility model relates to a kind of lead frame bender of IC punching formation equipment, especially a kind of automatic bender.
Background technology
On the production of IC punching formation equipment, to TO class lead frame before die-cut, all need it is carried out the bending of certain angle, each applying unit all has different requirements to lead frame bending angle, at present, the bending method that uses in the production is all finished by manually carrying out manual operation, the method that it adopts is, on pressing plate, be provided with and the adaptive groove of lead frame one side, at the hinged turnover panel in side of the slot opening of pressing plate, during use, earlier a side of single lead frame in groove, one side of lead frame plastic-sealed body again with the upset of hand propelled turnover panel, can reach the purpose of lead frame bending on turnover panel.The advantage of above-mentioned bending method is that device structure is simple, and cost is low, but its shortcoming be lead frame will be in the groove of pressing plate by manually arranging bending one by one, therefore operate cumbersome, material loading is consuming time, and production efficiency is low, simultaneously, manually bending relies on operator's experience to control the bending angle, cause the bending angle of each lead frame all to be not quite similar, error is bigger, is difficult to reach a unified standard, cause the quality of product low thus, the defect rate height.
Summary of the invention
The purpose of this utility model just provide a kind of stable, simple to operate, production efficiency is high, the automatic bender of the lead frame of a kind of IC punching formation equipment of good product quality.
By the automatic bender of the lead frame of a kind of IC punching formation equipment that the utility model proposes, it comprises frame, be fixed on pressing plate on the frame, with the hinged turnover panel of pressing plate, pressing plate is provided with and the adaptive groove of lead frame one side, and it also comprises lead frame is delivered to conveyer, upset cylinder and electrical control gear in the groove of pressing plate; Conveyer comprises a pair of drive unit that is roller, pinch roller and the driving rolls rotation of arranging and be arranged on pressing plate one end groove porch up and down, pinch roller is hinged on the frame by connecting rod, and frame is provided with and acts on connecting rod, makes the elastic mechanism that the pinch roller pair roller is exerted pressure by connecting rod; The telescopic shaft and the turnover panel of upset cylinder are hinged, make turnover panel upwards to overturn; Electrical control gear comprises the sensor whether the detection lead frame puts in place in groove.
Adopt said structure when work, lead frame is sent between roller and the pinch roller, pinch roller is pressed in lead frame on the roller under the effect of elastic mechanism, and send in the pressing plate groove with the rotation of roller, send the lead frame signal that puts in place by sensor again, electrical control gear starts the upset cylinder, promotes the turnover panel upset with the lead frame bending, has just reached the requirement of bending.
Enter resistance between roller and the pinch roller in order to reduce lead frame, above-mentioned elastic mechanism comprises stage clip, electromagnet, and magnet spool is arranged on the frame of connecting rod below, and the upper end and the connecting rod of armature are connected, and stage clip is located between connecting rod and the frame; Described electrical control gear comprises also whether a detection lead frame arrives the roller of conveyer, the sensor between the pinch roller.Lead frame is sent to before the conveyer, stage clip supporting linkage and pinch roller, and the pinch roller pair roller is not exerted pressure; Roll when lead frame arrives, between the pinch roller time, sensor sends the lead frame signal that puts in place, electrical control gear just starts electromagnet, armature drives connecting rod action and compression press spring downwards, the pinch roller pair roller is exerted pressure, thereby lead frame is clamped.
For improving bending efficient of the present utility model, it also comprises delivers to the roller of described conveyer, the ejecting device between the pinch roller with lead frame; Ejecting device comprises slide block, is fixed on the push rod on the slide block and can drives the drive unit that slide block is made back and forth movement that frame is provided with the horizontal guide pillar that cooperates with slide block.Because slide block is under the driving of drive unit, slide block is reciprocating, and the push rod that is fixed on the slide block is also done straight reciprocating motion, promote lead frame enter roll, between the pinch roller, thereby further improved efficient of the present utility model.
For further improving bending efficient of the present utility model, it also comprises a magazine and a lowering or hoisting gear thereof of depositing lead frame, described magazine is between lead frame conveyer and lead frame ejecting device, and magazine is provided with several in order to place the chute of lead frame on two madial walls of lead frame moving direction; Magazine fixture, screw mandrel and stepper motor that the magazine lowering or hoisting gear comprises lifting slider, is connected with lifting slider, frame is provided with the vertical guide rail that cooperates with lifting slider, screw mandrel is vertically set on the frame, lifting slider and screw mandrel cooperate the formation lead screw transmission mechanism, screw mandrel is rotatably connected on the frame, screw mandrel and stepper motor driving coupling.Adopt said structure, ejecting device is shifted the lead frame in the magazine onto conveyer, magazine is under the effect of lowering or hoisting gear, magazine is lifted, next lead frame in the magazine is lifted to the precalculated position like this, ejecting device can be released this lead frame again, thereby realizes continuous operation, has therefore further improved production efficiency of the present utility model.
In sum, because the utility model only needs lead frame is come in the magazine, again magazine is fixed on the magazine fixed mount, starting drive, can realize automatic continual bending work, therefore, the utility model is simple to operate, stable, production efficiency is high; Simultaneously, because the utility model is when bending, angle bending is fixed the bending angle of lead frame by the stroke adjustment of upset cylinder telescopic shaft, and therefore, the product that the utility model bending goes out also has the measured advantage of matter.
