Description
Technical field
The utility model relates to a kind of feeding device of IC punching formation equipment.
Background technology
In IC punching formation equipment, because being the wire length on two opposite flanks of plastic-sealed body, the structure of TO252/257 class lead frame do not wait, and the lead-in wire on the two sides is connected with the plastic-sealed body dislocation, therefore its center of gravity is not in its geometric center, when the easy run-off the straight when piling up of TO252/257 class lead frame, when material loading, can not satisfy die-cut requirement when causing manipulator or sucker to be difficult to extracting or extracting like this.So in traditional IC punching formation equipment, adopt single manipulator or sucker to be difficult to realize extracting to the TO252/257 class lead frame that piles up.In the existing integrated circuits punching formation equipment, material loading for TO252/257 class lead frame is achieved in that at the inclined-plane track that links to each other with the charging aperture of punching formation equipment, the TO252/257 class that tiles one by one in orbit lead frame is because bevelled support makes lead frame maintenance level.When die-cut, when manipulator or sucker grasp TO252/257 class lead frame of front end, the TO252/257 class lead frame of back glides on the inclined-plane, effect lower edge of gravity, fill up the vacant locations of front lead frame, manipulator or sucker are delivered to TO252/257 class lead frame to return behind the precalculated position and are grasped next lead frame again, so move in circles, realize the material loading of TO252/257 class lead frame.Therefore the advantage of this feed mechanism is simple in structure, but its shortcoming is: lead frame will be arranged one by one by artificial realization on the inclined-plane, operates cumbersomely, and material loading is consuming time, causes fluctuation of service, and production efficiency is low, and equipment takes up space greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of feeding device of TO252/257 class lead frame of stable, simple to operate, a kind of IC punching formation equipment that production efficiency is high.
Feeding device by a kind of IC punching formation equipment that the utility model proposes, it comprises the manipulator that is fixed on the support, it also comprises a positioning pressuring plate that lead frame is carried out level correction, described pressing plate is fixed on the below of manipulator along the lead frame length direction, the pressing plate bottom corresponds to lead-in wire position, lead frame both sides and is provided with boss, and the difference in height of two boss equates with the difference in height of the both sides of the lead frame that is grasped lead-in wire.
Adopt said structure, when TO252/257 class lead frame when piling up material loading, whole device moves down, pressing plate function is on lead frame, two boss of pressing plate are squeezed in respectively on the both sides lead-in wire of lead frame, and lead frame is remedied to horizontal level, grasp lead frame by manipulator again, send into assigned address, finish the material loading action.
Above-mentioned pressing plate links to each other with support by over-pressure safety device; described over-pressure safety device is made up of the axis of guide, the linear bearing that cooperates with the axis of guide and stage clip; pressing plate is fixed on the lower end of the axis of guide; linear bearing is fixed on the support; and be enclosed within on the axis of guide; it is spacing to the bottom position of pressing plate that axis of guide upper end is provided with position-limitting pin, is set with stage clip on the axis of guide between pressing plate and the support.When rising under the reaction force of pressing plate at lead frame, the pressing plate compression press spring makes pressing plate become flexibility with contacting by rigidity of lead frame, and impact energy is absorbed by stage clip, thereby reaches the protection to lead frame.
Described manipulator comprises adsorbent equipment and clamping device, adsorbent equipment comprises sucker, sucker mounting pipe and lift cylinder, lift cylinder is fixed on the support, the sucker mounting pipe is fixed on the piston rod of lift cylinder, sucker is installed in the bottom of sucker mounting pipe, sucker mounting pipe upper end is connected with the vacuum plant pipe, has hole or groove that sucker and sucker mounting pipe move up and down on the pressing plate; Described clamping device comprises tong and tong cylinder, and tong is positioned at the strip width both sides, and action makes tong realize opening and clamping to the tong cylinder to tong.
For prevent manipulator to be damaged or injure the bottom lead frame; support is connected by the installing plate of an over-pressure safety device with the walking of driving device hand; this device constitutes by stage clip, the axis of guide and with the adaptive linear bearing of the axis of guide; linear bearing is fixed on the installing plate; the axis of guide is fixed on the support; its upper end is passed linear bearing and is had position-limitting pin to carry out that it is spacing, and compression spring sleeve is contained on the axis of guide between installing plate and the support.When the suffered pressure in tong bottom surpasses the pressure of stage clip, support will compress the stage clip of this over-pressure safety device, make tong and lead frame be protected.
Destroy when adsorbent equipment on the support and clamping device parts can excessively not risen by pressing plate, on pressing plate, be provided with limited block and carry out spacing pressing plate.The rising of pressing plate like this is limited in certain scope the distance between pressing plate and the support, and the adsorbent equipment of manipulator and clamping device are protected.
In sum, because the utility model adopts after two boss being set on the pressing plate lead frame is carried out the rectification level, grasp material loading with manipulator again, realized the material loading of TO252/257 class lead frame when piling up, also realized the automatic charging from bottom to top of TO252/257 class lead frame, therefore the utility model is stable, simple to operate, the production efficiency height.
