A fully automatic preheating furnace

Abstract

The invention provides a fully automatic preheating furnace, comprising a furnace body frame, a battery loading station, a battery heating station and a battery unloading station, the battery heating station is located in a heating chamber of the furnace body frame, and the heating chamber Several layers of tray-type heating plates are set up and down in sequence. The tray-type heating plates can be horizontally moved and fixed in the furnace body frame through the heating plate guide assembly. It also includes pushing the tray-type heating plates to move back and forth to heat the battery at the charging station and battery. The heating plate toggle device for switching between the station and the battery unloading station. The invention adopts a tray-type heating plate that can be pushed out horizontally, which does not need to carry the gravity of the combination of heating plate groups, and reduces the deformation of the heating plate. Drag chains can be installed on both sides of the tray-type heating plate that can be pushed out horizontally to prevent cables and air pipes from moving. When breakage occurs, the tray-type heating plate is equipped with a dust removal negative pressure tube to increase the distance between the dust and the dust removal tube and increase the dust removal effect.

Description

technical field [0001] The invention relates to the technical field of lithium battery production equipment, in particular to a fully automatic preheating furnace. Background technique [0002] At present, the battery contact preheating process in the industry mainly relies on the lifting mechanism to lift the heating plate-the loading and unloading module takes the discharge core-the heating plate is stacked and heated to achieve the purpose of preheating the battery, and the front end of the air claw is equipped with a dust removal air knife Regularly remove dust from the heating plate; however, when lifting the bottom heating plate, it is necessary to lift all the heating plates above, resulting in greater force on the bottom heating plate, deformation of the bottom heating plate, and greater resistance between the guide rods when lifting , prone to failure; in addition, during the lifting process of the heating plate, because the heating plate cable is not fixed well, th...

[0002] At present, the battery contact preheating process in the industry mainly relies on the lifting mechanism to lift the heating plate-the loading and unloading module takes the discharge core-the heating plate is stacked and heated to achieve the purpose of preheating the battery, and the front end of the air claw is equipped with a dust removal air knife Regularly remove dust from the heating plate; however, when lifting the bottom heating plate, it is necessary to lift all the heating plates above, resulting in greater force on the bottom heating plate, deformation of the bottom heating plate, and greater resistance between the guide rods when lifting , prone to failure; in addition, during the lifting process of the heating plate, because the heating plate cable is not fixed well, the frequency of use is too high, which will lead to bad problems such as cable breakage; once the transmission mechanism of the heating plate group fails, other heating The board cannot output the internally baked cells; the dust removal by the air knife is 20mm away from the surface of the heating board, resulting in insufficient negative pressure, which cannot perfectly remove dust from the heating board
