The invention discloses a tunnel type oven berth mechanism suitable for automatic online and offline and belongs to the technical field of product postprocessing auxiliary devices. The mechanism comprises an entrance berth group, an exit berth group and a carrier, the entrance berth group is arranged at the entry end of a tunnel type oven through a lateral seat frame I, the exit berth group is arranged at the exit end of the tunnel type oven through a lateral seat frame II, gaps are reserved among the entrance berth group, the exit berth group and a link plate, and the carrier is automatically conveyed from the entrance berth group to the exit berth group through the link plate. According to the tunnel type oven berth mechanism suitable for the automatic online and offline, when the tunnel type oven is used for baking products, the automatic online and offline is achieved, unmanned and automated joint of working procedures from start to finish are convenient to achieve, the production cost is greatly reduced, the production efficiency is improved, the risk of human injuries caused by high temperature overflow wind of the oven entrance and exit is prevented, the product reject ratio caused by the fact that the manual picking and placing of products are prone to pollute product surfaces is avoided, the economic benefits are improved, and the tunnel type oven berth mechanism is easy to popularize and apply.
