Problems solved by technology

[0003] But the existing vacuum furnace has many deficiencies, for example: in the existing reflow soldering machine, the PCB circuit board needs to be preheated before being sent into the vacuum furnace by the furnace conveying assembly, but at a higher temperature, it is easy to Insufficient friction between the furnace conveying component and the PCB circuit board occurs, such as the board introducing device of the reflow soldering machine disclosed in a patent for the furnace conveying component (patent application number 200820046891.4) that the applicant applied for before the filing date , in an ultra-high temperature state, the friction coefficient of the chain will decrease, resulting in a decrease in the friction between the chain and the PCB circuit board, and finally the problem that the stroke of the PCB circuit board is wrong

Abstract

A vacuum furnace equipment for a reflow soldering machine comprises a rack (1), a lower furnace body (2), an upper furnace body (3) and a furnace entering conveying assembly (4), wherein the two endsof the rack (1) are provided with the lower furnace body (2) and the furnace entering conveying assembly (4) which are matched with each other respectively. The vacuum furnace equipment further comprises a furnace inlet poking assembly (5), an upper furnace body jacking assembly (6) and an upper furnace body heating assembly (7); and a plurality of grids (19) are arranged on the outer wall of a top plate of the upper furnace body (3). In the use process, the yield of an existing reflow soldering machine during production can be improved in a variety of ways such as improvement of stroke precision of workpiece conveying and heating temperature compensation of the furnace bodies of a vacuum furnace.

Description

technical field [0001] The invention relates to the technical field of reflow soldering machines, in particular to a vacuum furnace equipment for reflow soldering machines. Background technique [0002] In the current industrial production, reflow soldering machines are often used for reflow soldering of PCB circuit boards, among which the vacuum furnace is the core functional component of the reflow soldering machine. [0003] But the existing vacuum furnace has many deficiencies, for example: in the existing reflow soldering machine, the PCB circuit board needs to be preheated before being sent into the vacuum furnace by the furnace conveying assembly, but at a higher temperature, it is easy to Insufficient friction between the furnace conveying component and the PCB circuit board occurs, such as the board introducing device of the reflow soldering machine disclosed in a patent for the furnace conveying component (patent application number 200820046891.4) that the applican...
