Abstract
Description
Technical Field
[0001] The utility model relates to the field of processing technology, in particular to a paper tape punching die. Background Art
[0002] With the development of miniaturization of electrical appliances, the requirements for miniaturization of electronic components are getting higher and higher. Chip electronic components are the mainstream form of discrete electronic components at present, and their sizes are getting smaller and smaller. At present, it has developed to 0402 and even to 0201, and smaller ones can be made to 01005. At such a small scale, corresponding carriers must be available for aspects such as packaging, transportation, and picking up of components. Currently, plastic carrier tapes are generally used as packaging carriers. However, when the size is relatively large, using plastic carrier tapes is acceptable. When the size is smaller, it is very difficult to produce plastic carrier tapes, and it is difficult to guarantee their dimensional accuracy. Therefore, using paper carrier tapes as packaging carriers for micro-chip electronic components is an inevitable trend in the development of miniaturization of electronic components. Its processing technology is to punch two rows of holes in a paper carrier tape. One row is positioning round holes for easy identification by an automatic identification system, and the other row is square holes for placing chip electronic components. These holes are all punched by a punching die. For traditional punched round holes and square holes, the design of the punching die is very easy. However, during or after the punching process, the punching needle may slightly drive the paper tape to move, which may easily cause subsequent punching to deviate and result in unqualified products.
