(Prior art) For example, in high-temperature secondary batteries, bonded parts are used in which an insulator made of α-alumina and a lid made of an aluminum alloy are bonded, and a device for bonding such ceramics and metal is used. It is known that thermo-pressure bonding is carried out in a straight tunnel furnace type processing chamber maintained at high temperature in a high vacuum atmosphere.However, in conventional bonding equipment of this type, it is difficult to maintain a vacuum atmosphere before and after the processing chamber. The necessity of providing an air pressure adjustment chamber complicates the apparatus, and requires a pump with a large capacity to create a vacuum inside the processing chamber, resulting in a problem that the entire apparatus becomes large-scale and expensive. In addition, equipment that uses the hatch method to join ceramics and metals is also used, but the hatch method has problems such as complicated loading and unloading of workpieces, small processing capacity, and high costs. there were.

(Effects of the Invention) As is clear from the above description, the present invention enables efficient bonding work by a continuous processing method, unlike the conventional batch processing method, and also allows the vacuum chamber to be replaced externally with a tunnel furnace. Since heating is performed, temperature control is easy and heat curves corresponding to various heating conditions can be obtained.In particular, the carrier is a rotary table with a main vacuum chamber connected to a vacuum pump at the bottom, and each vacuum chamber is heated. When the main vacuum chamber can be moved into and out of contact with the main vacuum chamber via a valve, the capacity of each vacuum chamber can be reduced, and a drop in the degree of vacuum during work can be prevented, allowing a small-capacity vacuum pump to maintain a sufficient degree of vacuum. It is a compact device that can be maintained and has excellent workability.
