Description
Technical field
Sealed in unit field more particularly to a kind of lead frame for integrated circuit the utility model is related to automation
Transmission mechanism.
Background technology
In IC package field, the IC package mechanical equipment automated at present is usually by way of speed regulating motor and idler wheel
It is transmitted, position of the lead frame in transmission process is inaccurate, and holds in transmission process if encountering larger resistance
Fragile lead frame.By the way of suppressing lead frame using idler wheel, once lead frame does not aoxidize, surface is non-
Ordinary light is slided, and the idler wheel and lead frame surface of compacting can produce relative sliding, and can not generate enough frictional force, if increasing rolling
The weight of wheel increases frictional force, and can increase the risk of damage lead frame surface.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, transmission movement and accurate positioning for integrated circuit
Lead frame transmission mechanism.
In order to solve the above technical problems, the lead frame transmission mechanism described in the utility model for integrated circuit, packet
Two L-shaped pedestals are included, a side of one of L-shaped pedestal is connected with limit level sensor and belt wheel, is connected between belt wheel same
Walk band, the affixed servo motor in another side of L-shaped pedestal；Affixed one strip with the linear guide between two L-shaped pedestals
The spacing of shape support plate, an also affixed ball screw parallel with support plate between two L-shaped pedestals, support plate and ball screw
For the thickness of link block, link block is equipped with a spill sliding block, and the groove of sliding block is adapted with the width of the linear guide, lifting air
Cylinder is fixed on link block, and the centre position of lifting cylinder is equipped with caging bolt, and the elevating lever of lifting cylinder is connected with connecting plate
It connects, connecting plate and Pneumatic clamping jaw Joint.
To ensure the steady and reliability of lead frame transmission process, as further improvement of the utility model, connection
Plate is fixed with Pneumatic clamping jaw via pins.
Position to ensure lead frame transmission process ensures precision as the preferred of the utility model, lifting cylinder with pair
Channel solenoid valve is connected；Pneumatic clamping jaw is connected with double-channel solenoid valve.
The beneficial effects of the utility model in summary：Technical solution described in the utility model, when servo motor drives
Ball-screw moves, and the position of link block and Pneumatic clamping jaw is very accurately error very little, Pneumatic clamping jaw clamp leads frame
When interference volume can also be adjusted according to the fixture on head, by be mounted on the caging bolt among cylinder can adjust cylinder return
The stroke of receipts ensures orbit altitude during Pneumatic clamping jaw clamping.Thus since the utility model is using servo motor drive ball
Screw is moved, therefore the transmission process position of lead frame is very accurate, is convenient for vision-based detection；Due to Pneumatic clamping jaw
Clamping interference volume can adjust, therefore chucking power can also adjust, ensure not damaging for product, by the adjusting of cylinder stroke,
So as to ensure the accuracy of clamp leads frame transmission surface height；By the above-mentioned means, its transmission movement and positioning were both realized
Function, and it is conveniently replaceable product again, facilitate debugging, cost performance is also higher.
