After drilling holes in the PCB board, the pins need to be removed first, and then the tape at the bottom of the pad needs to be peeled off. The PCB board is conveyed forward by conveyor rollers and enters the conveyor belt. A photoelectric sensor detects the arrival of material, and a laser cutting head cuts the tape on both sides of the material in the middle. The tape is then directly detached, and the material continues to move forward by the conveyor belt. In the conveying process, when the material is sensed to reach the front of the scraper blade, the first lifting cylinder drives the pressure roller to press down, and the second lifting cylinder drives the scraper blade to rise. Under the pressure of the pressure roller, the scraper blade removes the tape from the bottom of the pad, leaving no residue and having no impact on the material. At the same time, the scraped tape falls into the tape recycling bin. After the tape is completely removed, the first lifting cylinder drives the pressure roller to rise, and the second lifting cylinder drives the scraper blade to fall, repeating the cycle continuously. This automatically removes the residual tape from the pad, replacing manual tape removal, significantly improving production efficiency, and saving labor costs and time.
