[0001] This utility model relates to the field of flexible circuit board protective film processing technology, specifically a device for one-time molding of long-length protective film. Background Technology
[0002] In the flexible printed circuit board (FPCB) manufacturing industry, a protective film is needed to wrap and protect bundled circuits. In actual production and processing, the protective film needs to be processed into the shape required by the customer and then applied to protect the circuits.
[0003] Traditionally, all window openings are formed in one go using a single die and punch, ensuring stable stamping offset. Considering the die's punching range, processing accuracy, equipment, and manufacturing costs, commonly used dies are typically within 400mm in size. However, with changing customer needs, some customers now require protective films longer than 400mm. This necessitates designing dies for lengths exceeding 400mm, which requires adjustments to existing stamping equipment and processes, resulting in significant difficulty and cost. Therefore, a device for one-step forming of long-length protective films is provided to address these issues. Utility Model Content

[0013] Preferably, positioning holes are provided at the center of both ends of the secondary stamping die groove, and positioning shafts are fixedly provided at the four corners of the main stamping die groove. The two sets of secondary dies are positioned by movably inserting into the positioning holes on their surfaces and the two sets of positioning shafts on the same side.
[0014] This utility model discloses a device for one-time molding of long-length rubber sealant, which has the following beneficial effects:
[0015] This device for one-time forming of long-length protective film adopts a scheme of setting auxiliary molds on both sides of the top of the main mold. The main mold has a main mold slot for fixing the main mold, and the auxiliary mold has a secondary mold slot for installing the auxiliary mold. At the same time, a specially shaped punch hole is used to fix the image recognition hole of the second set of protective film mold.
