Smart pcb oven for remote monitoring

Abstract

The invention discloses a smart PCB (printed circuit board) oven capable of realizing remote monitoring. The smart PCB (printed circuit board) oven comprises an oven main body, an oven door and an exhaust gas purifying chamber; a baking chamber and the exhaust gas purifying chamber are arrange in the oven main body; five heating devices are arranged in different positions in the baking chamber; anair discharging hole and an air incoming hole are formed in the outer top part of the oven main body; an air extraction device and a hot air blower are arranged in the oven main body; the air extraction device and the hot air blower are connected through a main air supply pipe; the middle section of the main air supply pipe is located in the exhaust gas purifying chamber; the output end of the hot air blower is connected with the heating devices; a plurality of air outlets are arranged at one side of each of the heating devices which faces the baking chamber; a controller is arranged in the oven main body; and a micro processing unit, a wireless communication module and a buzzer are arranged in the controller. When the smart PCB (printed circuit board) oven is used, the remote monitoringof the working state of the PCB oven can be realized, multi-directional, comprehensive and uniform heating, baking and hot air circulation drying can be realized, the recycling of heat can be realized, and energy can be effectively saved.

Description

technical field [0001] The invention relates to a PCB oven, in particular to an intelligent PCB oven capable of realizing remote monitoring. Background technique [0002] In the process of PCB board processing, it is usually necessary to bake the PCB board to fully relax the stress of the substrate, thereby reducing the warping deformation of the substrate during the PCB manufacturing process. At present, the oven used for baking PCB boards is usually a double-layer steel box structure inside and outside. When baking PCB boards, hot air needs to enter the baking chamber of the oven to cooperate with accelerated drying. The waste air with heat and water vapor in the oven is exhausted, and the new hot air enters to realize circular drying. Existing PCB ovens need to manually control the baking temperature and time, and once there are many PCB ovens working at the same time, it is very inconvenient to implement, and the existing PCB ovens usually do baking operations. The air...

Problems solved by technology

[0003] The present invention aims at the problem that the PCB ovens in the prior art need to manually monitor the baking temperature and time, and provides an intelligent PCB oven that can realize remote monitoring. When it is applied, it can realize remote monitoring of the working state of the PCB oven. , and it can also carry out multi-directional, comprehensive and uniform heating and drying of the PCB placed in it and hot air circulation drying to improve the baking efficiency. At the same time, it can also use the heat of the exhaust gas to initially heat the newly drawn air. Realize the recycling of heat and effectively save energy
