The carrier and workpiece are then lifted by the first lifting mechanism. The assembly mechanism picks up graphite sheets from the feeding mechanism and attaches them to the workpiece. Then, driven by the assembly mechanism, rollers roll back and forth on the graphite sheets, squeezing them to initially bond them to the workpiece. The carrier moves above the second lifting mechanism under streamlined drive. The carrier and workpiece are then lifted by the second lifting mechanism. The first scraper, driven by the scraping mechanism, scrapes the graphite sheet back and forth along the X-axis, and the second scraper, driven by the scraping mechanism, scrapes the graphite sheet back and forth along the Y-axis. This back-and-forth scraping in both directions ensures the graphite sheet adheres completely to the workpiece.

This also reduces the impact of air bubbles on heat conduction. Then, the carrier and workpiece move to the streamlined discharge end under streamlined drive. This design offers the advantage of excellent fit. Attached Figure Description
