Problems solved by technology

[0004] (1) There is only one heating zone that matches the vacuum processing device on the machine table. Since the material needs to be heated to a certain temperature to melt the solder paste and achieve the welding effect, the heating of the material requires time to move , resulting in a long heating time, and because the heating zone is set on the upper cover, the heating zone uses radiation to heat the material, and the heat transfer efficiency is low, which further increases the heating time of the material, making its welding efficiency low ;
[0005] (2) The temperature of the blanks after welding is to

Abstract

The invention provides a welding mechanism of a vacuum welding furnace, belonging to the technical field of vacuum welding. The mechanism is characterized by comprising a welding chamber (18), and a furnace cover which is arranged at the upper side of the welding chamber (18), wherein a welding cavity is arranged between the furnace cover (4) and the welding chamber (18); a welding platform (20) is arranged at the lower part of the welding chamber (18); a heating area is arranged at one side, close to the feeding end, of the welding platform (20); a cooling area is arranged at one side, closeto the discharging end, of the welding platform (20); a negative pressure pumping module (9) is arranged at the upper side of one end, close to the cooling area, of the heating area; the negative pressure pumping module (9) is mounted on the furnace cover (4) by lifting, and the bottom part of the negative pressure pumping module (9) encircles a closed negative pressure chamber with the heating area; a protecting gas inlet pipe is arranged on the welding chamber (18) or the furnace cover (4). With the adoption of the mechanism, sheets can be quickly welded in the negative pressure cavity and are prevented from reacting with oxygen during heating.

Description

technical field [0001] A welding mechanism of a vacuum welding furnace belongs to the technical field of vacuum welding. Background technique [0002] During the production of electronic components such as diodes, triodes, thyristors or bridges, chips need to be welded between the upper material and the lower material. This process is called bonding. The specific working process of the assembling is as follows: First, it is necessary to apply solder paste on the upper side of the lower material, and place the chip on the specific position of the lower material, and then stack the upper material with the solder paste on the lower side on the lower material. On the upper side of the sheet, cover the top cover of the welding mold on the bottom plate of the welding mold, and finally send the welding mold into the welding furnace for welding. The welding of blanks needs to be carried out in a vacuum furnace. [0003] The Chinese utility model patent with application number 2014...
