Problems solved by technology

However, when the equipment processes electronic products with a height of only 10mm, since the maximum board entry height cannot be adjusted, a height of 20mm is completely wasted, and a large amount of heat and nitrogen will escape through this gap, resulting in power consumption and nitrogen consumption. Unnecessary increase, increased operating costs, resulting in waste

Abstract

The invention relates to a device for adjusting inlet height of a hearth. The device comprises the hearth, a hearth baffle plate, a steel wire drawing line, a steel wire fixing sheet, a connection support and a control handle; the hearth baffle plate is fixed on the hearth; the connection support is fixed on the hearth baffle plate; the steel wire fixing sheet is fixed on the connection support; one end of the steel wire drawing line sequentially penetrates through the steel wire fixing sheet and the connection support and then is fixedly connected with the hearth baffle plate; and the other end of the steel wire drawing line is connected with the control handle. Compared with the prior art, the device for adjusting the inlet height of the hearth has the advantages of reducing operation cost, along with convenience in operation, wide using range and the like.

Description

technical field [0001] The invention relates to a technology related to a reflow soldering furnace, in particular to a furnace inlet height adjusting device. Background technique [0002] Reflow oven is a kind of welding equipment used in SMT industry. It can provide an automatic and stable heating environment, so that the solder paste in the furnace is heated and melted, so that the pre-mounted electrical components on the PCB and the PCB board are reliably combined through the solder alloy. The production capacity of the reflow oven is limited by two important parameters - the height of the furnace inlet and the width of the furnace inlet. These two parameters determine that the reflow oven can handle the maximum board width and maximum board height. [0003] For customers, they hope that the same reflow oven can be used in a wide range of applications. The wider the width of the board that can be processed, the better, and the higher the height of the board that can be ...
