Principle and effect of the technology: when the PCB board toasts in toasting the case, the printing ink waste gas that produces is got into the processing incasement through ventilating fan, then handles the fluid-discharge tube in the case and evenly sprays out industrial ethanol through atomizer, makes it absorb printing ink waste gas.

Further, a connecting pipe is arranged between the liquid discharge pipe and the top of the treatment box.

By adopting the scheme, the liquid discharge pipe is convenient to install and disassemble.

Further, a temperature sensor is mounted on an inner side wall of the oven.

By adopting the scheme, the temperature in the baking oven can be conveniently known in time by staff.

Further, a liquid outlet pipeline is communicated with the bottom of the right side of the treatment box, and a switch valve is arranged on the liquid outlet pipeline.

By adopting the scheme, the waste liquid in the treatment box can be discharged in time by a worker conveniently.

Further, all the atomizing nozzles are arranged on the liquid discharge pipe at intervals.

By adopting the scheme, the industrial ethanol can be uniformly sprayed in the treatment box.

Compared with the prior art, the utility model has the beneficial effects that: the printing ink waste gas generated during the baking of the PCB can be timely disposed, so that the harm to the health and the environment of workers is avoided.

Detailed Description

The following is a detailed description of the embodiments.

Examples: as shown in fig. 1, a PCB baking apparatus includes a support frame 1, and a plurality of support columns disposed at intervals are inserted at the top of the support frame 1. The upper left side of support frame 1 installs stoving case 2, and the inside grafting of stoving case 2 has backup pad 3, has pegged graft on backup pad 3 and has the pillar 4 that many intervals set up, and the PCB board can be placed on pillar 4, and the infrared stoving lamp 5 that a plurality of intervals set up is still installed at the top of stoving case 2, installs temperature sensor 15 on the inside left side lateral wall of stoving case 2. The upper right side of the support frame 1 is provided with an exhaust gas treatment component which comprises a treatment box 8, a transfusion tube 9 and a plurality of atomizing spray heads 12. An exhaust pipe 6 is communicated between the right side of the baking oven 2 and the left side of the processing box 8, a ventilating fan 7 with a motor is arranged in the middle of the exhaust pipe 6, and the ventilating fan 7 can timely discharge ink waste gas in the baking oven 2 into the processing box 8. One end of the infusion tube 9 passes through the top of the treatment box 8, the other end of the infusion tube 9 is communicated with a storage container of industrial ethanol, a water pump is further installed in the storage container of industrial ethanol, the water outlet end of the water pump is communicated with the infusion tube 9, and the liquid discharge tube 10 is communicated with one end of the infusion tube 9, which is positioned in the treatment box 8.
