The invention discloses a winding type discharging device for lead frame production, and relates to the technical field of lead frames. The winding type discharging device for lead frame production comprises a box body and a plate material, wherein a placement groove is formed in the top of the box body. According to the winding type discharging device for lead frame production, when the winding type discharging device is adjusted to the position above a placement position, a first supporting wheel moves upwards, a second supporting wheel moves downwards, and the plate material and a placement barrel are supported through the first supporting wheel; and due to the fact that the first supporting wheel and the second supporting wheel are perpendicularly arranged, when the plate material and the placement barrel are supported through the first supporting wheel, the positions of the plate material and the placement barrel cannot move and are convenient to fix; a baffle is connected with a box body through a rotating plate, so that the position of the baffle is convenient to adjust; through cooperation of a first positioning barrel, a positioning rod and a second positioning barrel, the position of the baffle is convenient to fix; and the position of a placement rod is fixed through the baffle and the box body, so that the position of the placement barrel is fixed, and operation is easy.
Description
technical field [0001] The invention relates to the technical field of lead frames, in particular to a winding-type unwinding device for lead frame production and a working method thereof. Background technique [0002] As the chip carrier of integrated circuits, the lead frame is a key structural part that realizes the electrical connection between the lead-out end of the chip's internal circuit and the outer lead by means of bonding materials (gold wire, aluminum wire, copper wire) to form an electrical circuit. When it comes to the bridge function of connecting with external wires, most semiconductor integrated blocks need to use lead frames, which are important basic materials in the electronic information industry. [0003] The lead frame is produced through the corresponding material board. In order to facilitate transportation, the material is rolled on the placement cylinder. During production, the placement cylinder needs to be moved to the working position. The exis...
