AI Technical Summary
Technical Problem
Existing tunnel furnaces have the risk of misalignment and card breakage due to low friction during substrate transport, affecting transport stability.
Method used
The design employs a transfer roller system, including an elastic support ring and a limiting plate. The elastic support ring deforms under product pressure to increase the contact area and friction, while the limiting plate prevents deviation. Combined with the ceramic transfer unit and drive mechanism, stable transmission is ensured.
Benefits of technology
This improves the stability of substrate transmission, reduces deviation and card-related risks, and ensures the smooth progress of the high-temperature crystallization process.

Abstract
This utility model belongs to the field of photovoltaic module manufacturing technology, and discloses a transfer roller and a tunnel furnace transfer device. The transfer roller includes a body, an elastic support ring, and a limiting plate. The elastic support ring is fixedly sleeved on the body; the limiting plate is circular and fixedly connected to the outer periphery of the body. During transfer, the bottom surface of the product can press against the outer periphery of the elastic support ring, and the edge of the product can press against the limiting plate. The elastic support ring can rotate synchronously with the body under its drive, providing support for the product. Due to its elasticity, the elastic support ring can undergo elastic deformation under the pressure of the product, thereby increasing the contact area and friction between the two to prevent slippage. The limiting plate prevents the product from deviating or tilting during transfer, resulting in high stability and low risk of deviation and jamming.
