Sealing structure of electronic product annealing or sintering furnace and carrying cart

Abstract

The invention relates to a sealing structure of an electronic product annealing or sintering furnace and a carrying cart, and belongs to the technical field of industrial furnaces. The annealing or sintering furnace comprises a furnace frame, a furnace body, a furnace pipe, a heating device and a hot air circulating device, and the carrying cart comprises cart guide rails and a carrying cart body. The sealing structure is characterized in that: a horizontal frame body of the furnace pipe is provided with a horizontal sealing plate of the frame body; a longitudinal frame body of the furnace pipe is provided with a longitudinal sealing plate of the frame body; the upper end of the horizontal sealing plate of the frame body is jointed with the horizontal sealing plate of the frame body; a furnace pipe fixing plate is provided with a sealing bar; the cart guide rails are fixed on both sides of the furnace frame; the carrying cart body comprises a moving base and a carrying plate; the moving base is arranged on the cart guide rails; the carrying plate is arranged on the upper part of the moving base; both sides of the carrying plate are provided with sealing bar bases; each sealing bar base is matched with the sealing bar; the upper part of the carrying plate is provided with a sealing plate; and the sealing plate is provided with a first sealing plate and a second sealing plate. The sealing structure has the advantages that: energy is saved, and the annealing or sintering quality of the electronic product is ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, and in particular relates to a sealing structure of an electronic product annealing or firing furnace and a loading trolley. Background technique [0002] As is well known in the industry, the production of many electronic products needs to be annealed or fired. Into a furnace. In recent years, people have paid more and more attention to PDP as a large-image flat-panel display for wall-mounted TVs and multimedia displays. my country's industrial production process has been significantly accelerated, and the country has also implemented a plan to promote the localization of flat-panel TVs. PDP is a component (that is, a display) that injects a mixed gas between two ultra-thin glass plates and applies voltage to use phosphors to emit light and form images. Compared with CRT picture tube displays, it has high resolution, large screen, ultra-thin, and rich colors. Compared with LCD, it ...

Problems solved by technology

[0005] The technical problem that plagues the industry in the existing technology is: the annealing or firing furnace and the loading trolley for electronic products cannot meet the desired sealing degree, and the heat in the furnace is not only easily lost from the bottom of the furnace cavity of the furnace body, It also escapes from the inlet and outlet of the furnace, which not only causes energy waste, but also affects the quality of electronic products.
