Description
Technical Field
The utility model belongs to a semiconductor package technical field, concretely relates to lead frame stamping die belt cleaning device.
Background
Lead frames are an important basic component in the electronic information industry. The lead frame is used as a chip carrier of the semiconductor integrated circuit, and the electrical connection between the leading-out end of the internal circuit of the chip and the external lead is realized by means of a gold bonding wire, so that a key structural member of an electrical loop is formed, and the lead frame plays a role of a bridge connected with an external lead. The lead frame is manufactured by two methods, namely a stamping method and an etching method. The punching method mainly comprises four working procedures of punching, electroplating, forming and sorting. The blanking is a stamping process for separating plates by using a die, and comprises various working procedures such as cutting, blanking, punching, trimming, notching and the like, wherein the blanking and the punching are most widely applied. Punching a part (or blank) with a required shape from a plate material is called blanking. Punching a hole of a desired shape (the punched hole is a waste material) in a workpiece. The blanking may be performed to obtain a flat plate part, or may be performed by bending, drawing, forming, or the like.
The stamping die is the main equipment for producing lead frames. With the development of lead frames toward wider, thinner, multi-row, and high-foot materials, the stamping dies are also moving toward smaller punches, smaller gaps, more foot counts, and higher process (flatness, lateral bending, high-low foot, etc.) requirements. The precision, strength and service life of the stamping die directly affect the quality, production efficiency and manufacturing cost of the lead frame. Therefore, the technology of stamping and molding represents the technical level of the lead frame manufacturing industry, and is the technology occupying the core position in the industry competition.
After the blanking die sharpening has accomplished the edge of a knife, the residue after a large amount of cutting liquid and grinding is remained to mould surface and inside, originally can only wash the mould at fork truck or bench worker mesa, or unpack each subassembly of mould one by one and wash, and so not only expend man-hour, and when kerosene or alcohol were as the washing liquid, its volatile substance can seriously pollute workshop 6S environment, still had the conflagration hidden danger, still had the risk that the mould washing did not thoroughly bring simultaneously.
Secondly, as an expensive high-precision die, in the production of a lead frame, a stamping die often adheres to some small sundries such as stamping scraps, oil stains, workshop dust and the like, if the die is not thoroughly cleaned, the surface of the lead frame is polluted, the manufacturing precision and the surface flatness of the lead frame are influenced, the lead frame is easy to deform, quality problems occur in the chip packaging process, the production yield, the production efficiency and the manufacturing cost are seriously influenced, the stamping die is seriously abraded and damaged, the service life of the stamping die is shortened, and huge economic losses are caused.
