Structure of sintering furnace conveyor belt

Abstract

The invention discloses a structure of a sintering furnace conveying belt. A structure of a sintering furnace conveying belt comprises a winding wire and a tandem shaft, and the tandem shaft is arranged in a wave shape and comprises wave crest sections and wave trough sections which are alternately arranged and sequentially connected. And the same winding wire sequentially passes through the wave trough section of one tandem shaft and the wave crest section of the adjacent tandem shaft. The tandem shaft of the conveying belt is changed from a linear rod shape to a wave shape, meanwhile, the sizes such as the diameter of a winding wire and the diameter of the tandem shaft are increased, and the service life of the sintering furnace conveying belt is prolonged.

Description

Technical Field

[0001] This invention relates to the field of DCB substrate manufacturing, and specifically to sintering conveyor belts. Background Technology

[0002] The sintering furnace conveyor belt consists of wire winding and shaft winding. During sintering, the copper foil and ceramic plate of the DCB substrate are placed on the conveyor belt and fed into the furnace for sintering. See [link to relevant documentation]. Figure 1 .

[0003] Because copper foil and ceramic plates have a certain weight, when placed and pressed in the middle of the conveyor belt, the left and right sides of the conveyor belt spool are subjected to significant tension, easily causing bow-shaped deformation. Once the spool deforms, the wires wound on it will slide to both sides, accelerating the bow-shaped deformation, narrowing the conveyor belt, and affecting the placement of sintered products; or the spool may break due to excessive deformation. Currently, the service life of sintering furnace conveyor belts is approximately 3 months before replacement. Figure 2 . Summary of the Invention

[0011] More preferably, the outer diameter of the spool is 3.0 mm to 3.5 mm;

[0012] The crest and trough segments are curved in a semi-circular arc shape, and the radius of the arc of the crest and trough segments is 6mm to 8mm.

[0013] More preferably, on the same axial section, the spacing between adjacent crests is 7mm to 10mm, and the spacing between adjacent troughs is equal to the spacing between adjacent crests.

[0014] More preferably, the diameter of the winding wire is 2.5mm to 3.0mm.
