The invention discloses a special-shaped Mylar separation device. The special-shaped Mylar separation device comprises a U-shaped machine frame, a reeling assembly, an unreeling assembly, a driving assembly and a separation device; the driving assembly comprises a first driving roller, a second driving roller, a third driving roller and a fourth driving roller which are hinged to the U-shaped machine frame; the separation comprises a suction disk and a separation rod; the suction disk is arranged between the second driving roller and the third driving roller; the separation rod can move left and right; a base material tensioning mechanism is arranged between the suction disk and the third driving roller; the base material tensioning mechanism comprises a liftable tensioning roller; the stretching end, wound on the unreeling assembly, of a base material sequentially passes through the lower side of the fourth driving roller, the upper side of the third driving roller, the upper side ofthe tensioning roller, the part below the suction disk, the upper side of the second driving roller and the lower side of the first driving roller; the base material finally is wound on the reeling assembly; and the driving assembly and the separation rod are provided with the same set of intermittent driving mechanism. The local or overall tearing phenomenon is avoided when special-shaped Mylar is torn down from the base material.
Description
Technical field: [0001] The invention relates to the technical field of electronic product processing, in particular to a special-shaped Mylar separation device. Background technique: [0002] Mylar is a famous brand of polyethylene terephthalate (PET) under dupont. It is a tough polyester polymer with good heat resistance, surface smoothness, transparency and mechanical flexibility. It is used in packaging, printing, photocopying and flexible electronics. and other fields have a wide range of applications. Before use, Mylar is generally attached to a smooth flexible substrate in sequence. When in use, Mylar is peeled off from the substrate, and then the sticky side of Mylar is attached to the corresponding position of the electronic product. When the staff is actually attaching Mylar, they will encounter Mylar of various shapes (referred to as special-shaped Mylar in this paper). For example, Mylar is in a concave shape. Overall tearing phenomenon. Invention content: ...
