The device of replacing lead frame of the present utility model, its running is as follows: when the first lead frame load carrier loads onto a new volume lead frame, first inductor detects this signal and by Signal transmissions to processor, processor receives this signal, control the first driving stage work, first lead frame load carrier of the first driver drives and its interlock slides into above lead frame track along the first cross bar, stop motion, now lead frame is connected with packaging machine by lead frame track, and lead frame is sent into packaging machine, when the lead frame on the first lead frame load carrier runs low, a new volume lead frame is installed on the second lead frame load carrier, when the lead frame on the first lead frame load carrier is finished, first inductor will detect that this signal is sent to processor, processor controls the first driving stage work, first lead frame load carrier of the first driver drives and its interlock slides off lead frame track along the first cross bar, get back to initial position, and then control the second driving stage work, second lead frame load carrier of the second driver drives and its interlock slides into above lead frame track along the second cross bar, stop motion, now lead frame is connected with packaging machine by lead frame track, and lead frame is sent into packaging machine, when lead frame on the second lead frame load carrier runs low, a new volume lead frame is installed on the first lead frame load carrier, then, when the lead frame on the second lead frame load carrier is finished, second inductor will detect that this signal is sent to processor, processor controls the second driving stage work, second lead frame load carrier of the second driver drives and its interlock slides off lead frame track along the second cross bar, gets back to initial position, then start to repeat above-mentioned workflow.
Adopt the design of said mechanism, processor drives the first lead frame load carrier to slide along the first cross bar according to signal controlling first driving mechanism of the first inductor, the second lead frame load carrier is driven to slide along the second cross bar according to signal controlling second driving mechanism of the second inductor, the two hockets, realize the quick-replaceable to lead frame, in use, only need lead frame load carrier in lead frame package, all the other work all can realize Automated condtrol, make the replacing of lead frame more quick, accurately, the waste that legacy equipment brings in lead frame Renewal process can be avoided.
In the utility model, preferred scheme be described first driving mechanism comprise the first motor, with the first screw mandrel of the first motor linkage, described first screw mandrel and the first lead frame load carrier are spirally connected.
In the utility model, preferred scheme be described second driving mechanism comprise the second motor, with the second screw mandrel of the second motor linkage, described second screw mandrel and the second lead frame load carrier are spirally connected.
In the utility model, preferred scheme is described first inductor is infrared inductor.
In the utility model, preferred scheme is described second inductor is infrared inductor.
In the utility model, preferred scheme is described first lead frame load carrier is rolling bearing, and described rolling bearing comprises outer ring, inner ring and rolling element, and described inner ring connects with the first driving mechanism.
In the utility model, preferred scheme is described second lead frame load carrier is rolling bearing, and described rolling bearing comprises outer ring, inner ring and rolling element, and described inner ring connects with the second driving mechanism.
Compared to existing technology, the beneficial effects of the utility model are: the design adopting said mechanism, processor drives the first lead frame load carrier to slide along the first cross bar according to signal controlling first driving mechanism of the first inductor, the second lead frame load carrier is driven to slide along the second cross bar according to signal controlling second driving mechanism of the second inductor, the two hockets, realize the quick-replaceable to lead frame, in use, only need lead frame load carrier in lead frame package, all the other work all can realize Automated condtrol, make the replacing of lead frame more quick, accurately, the waste that legacy equipment brings in lead frame Renewal process can be avoided.
