Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to a novel FPC soft board punching and cutting jig. Background Art
[0002] At present, stamping and cutting jigs are completed by punching out the whole reel of material. Single products are not separated from the material. When in use, the products need to be cut from the material. The current cutting machines cut the whole reel into sections, and each section has a set number of products. When assembling the products, the products need to be manually removed from the material. On the one hand, manual breaking is time-consuming, resulting in a significant reduction in assembly efficiency.
