Technical Field
[0001] This utility model relates to the field of automatic sorting technology for die-cut tapes, and in particular to a die-cut tape screening machine. Background Technology
[0002] Die-cutting is a molding technology widely used in the manufacture of packaging tapes. This process utilizes die-cutting blades, assembled into a die-cutting plate according to product design requirements. Under pressure, the tape or similar sheet-like blank is cut into a specific shape or forms slits. The tape product obtained through this die-cutting process is called die-cut tape.
[0003] In recent years, with the rapid development of automobiles, mobile phones, electronics and other fields, the demand for die-cut tape has been increasing. However, this growth has also brought new challenges, especially in the process of visually screening die-cut tape, where the excessive reliance on manual labor has become a prominent problem.
[0004] Currently, the vast majority of die-cut tape production still relies on manual visual inspection to screen the tape's appearance. This traditional manual screening method is proving significantly inefficient in the context of a rapidly expanding market. The appearance quality of die-cut tape is easily affected by various factors, including tape material and mold design, such as color, size, presence of excess adhesive, and thoroughness of waste removal. Operators must meticulously observe and select each tape individually. This not only leads to immense labor intensity and high production costs, but manual screening is also susceptible to subjective judgment, making it difficult to ensure consistent screening standards and thus affecting the quality stability of the final product. Furthermore, the increasing shortage of labor resources and rising labor costs further exacerbate the predicament of the traditional manual screening method.
