3) And (3) solder pasting: the solder is placed in the vibration powder pool, the foil belt with the glue is penetrated through the vibration powder pool, and the vibration powder pool vibrates, so that the solder can be adhered to the foil belt;
4) And (3) air drying: air-drying the foil tape stuck with the solder through air-drying equipment;
5) And (5) coiling and forming: the foil is coiled into the porous metal honeycomb carrier inner core through a coiling mould.
As a further improvement of the above technical scheme:
after dispensing, the glue points are flattened by rolling the upper roller and the lower roller through the foil belt.
And (5) after the glue points roll flat, pre-air-drying through air-drying equipment.
The dispensing adopts a dispensing machine, and the dispensing quantity of the dispensing machine is adjustable.
The air drying equipment comprises an air heater arranged on the upper side of the foil belt, and the air outlet quantity of the air heater is adjustable.
The vibrating powder pond is connected with a vibrating motor, and the vibrating motor can adjust the vibrating frequency of the vibrating powder pond.
Compared with the prior art, the invention has the following beneficial technical effects:
1) Because the glue and the solder are not mixed in advance, the problem of the influence of solder precipitation on the carrier performance is solved;
2) The problem that solder can only be uploaded regionally is solved by adopting a dispensing mode;
3) The roller rolls the glue to be flat and then passes through the powder pool, so that the problem of large solder uploading loss is solved;
4) The requirement of the solder on technicians is reduced because the solder is not required to be prepared in advance, and the requirement of the use of the solder on the environment is also solved;
5) The same performance is achieved, the amount of the used solder is greatly reduced, and the material cost is reduced;
6) The solder blending work and the drying work are reduced, the production period is shortened, and the production cost is reduced;
7) Solves the problem of carrier hole blocking;
8) The available foil tape cutting mechanism cuts the tape with fixed length for rolling, thereby ensuring the consistency and production efficiency of the tightness of the carrier and improving the stability of the quality of the carrier.
