A uv baking oven for pcb printed circuit board

Abstract

The invention discloses a UV baking furnace for PCB printed circuit boards, which comprises a furnace body and a UV layer arranged on the inner top of the furnace body. A reflective layer is arranged at the inner bottom of the furnace body. The body is symmetrically provided with a material inlet and a material outlet, and the material inlet is connected with a loading buffer platform for transporting the circuit board to be baked to the inside of the furnace body, and the material outlet is connected with a The baked circuit board is sent out of the automatic discharge device outside the furnace body. An overhead transmission mechanism between the UV layer and the reflective layer is arranged in the furnace body. One end of the overhead transmission mechanism is connected to the The above material loading buffer platform is connected, the other end of the overhead transmission mechanism is connected with the automatic discharge device, the circuit board is fixed overhead in the furnace body through the overhead transmission mechanism, and the overhead transmission mechanism clamps and fixes the edge of the circuit board, so that the circuit board There is no shelter during the curing process in the furnace body, thereby improving the curing efficiency.

Description

technical field [0001] The invention relates to the technical field of circuit board printing, in particular to a UV baking oven for PCB printed circuit boards. Background technique [0002] The names of circuit boards are: circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards may be referred to as printed wiring boards or printed circuit boards. During the circuit board production process, the circuit board needs to be dried. [0003] The UV baking device is mainly used to cure and dry UV glue, UV paint or UV ink, and is widely used in laboratories or production lines. The UV baking device includes an assembly line pa...
