[0043] like Figure 1-10 As shown, the embodiment of the present invention provides a baking device for PCB processing, including a baking oven 1, a fixing bolt 101 is fixedly connected to the top of the baking oven 1, and there are two fixing bolts 101 in total.

There are two rotating shafts 109, and the outer walls of the two rotating shafts 109 are movably connected with a conveyor belt 110, and the conveyor belt 110 cooperates with the feed port 105. The outer wall of the baking oven 1 is connected with a cooling mechanism 2 through. In this setting: first, the PCB circuit board is manually placed from the feed port 105 to the conveyor belt 110, and then the sealing plate 104 covers the feed port. 105, so that the internal space of the baking oven 1 becomes sealed, and then the baking lamp 402 emits heat, so that the heat bakes the PCB circuit board on the conveyor belt 110, and the PCB circuit board is dried by baking the PCB circuit board, and the waste gas heat emitted by the PCB circuit board during baking will be sucked into the processing box 302 by the waste gas suction pipe 301, and the waste gas is purified by the waste gas purification device 306 in the processing box 302 to prevent pollution of the external environment. When the purified gas in the processing box 302 increases, the air pressure increases to move the air pressure plate 307 backward, and then the purified gas flows into the cooling chamber 309 to cool the purified gas, and then the first motor 203 is started to rotate the first fan 202, and the gas in the cooling chamber 309 and the cooling pipe 201 is sucked into the baking oven 1 through the rotation of the first fan 202, so that the PCB circuit board on the conveyor belt 110 is cooled down, and the device purifies the waste gas generated after the PCB circuit board is baked, so that the waste gas can be recycled to prevent the waste gas from polluting the external environment.

[0044] Furthermore, the cooling mechanism 2 includes a cooling pipe 201 and a first fan 202. The cooling pipe 201 is connected to the baking oven 1 through and there are a plurality of cooling pipes 201. The inner wall of each cooling pipe 201 is fixedly connected to a first motor 203. The outer wall of the first motor 203 is fixedly connected to a first fixing rod 204. The first fixing rod 204 is fixedly connected to the cooling pipe 201.

The bottom of the cooling pipe 201 is fixedly connected to an exhaust gas treatment mechanism 3. This configuration: by starting the first motor 203, the first fan 202 is rotated. Through the rotation of the first fan 202, the gas in the cooling pipe 201 and the cooling cavity 309 is sucked into the baking oven 1. Because the first fan 202 is close to the conveyor belt 110, the blown gas cools down the PCB circuit board of the conveyor belt 110 to prevent the PCB circuit board from overheating after high-temperature baking, making it impossible for the staff to take it.

[0045] Furthermore, the exhaust gas treatment mechanism 3 includes an exhaust gas suction pipe 301 and a treatment box 302, the treatment box 302 is fixedly connected to the cooling pipe 201, a plurality of exhaust gas suction pipes 301 are provided, the exhaust gas suction pipes 301 are connected through the bottom plate 106, the inner wall of each exhaust gas suction pipe 301 is fixedly connected to a second motor 303, the second motor 303 is provided with a second fan 304, the exhaust gas suction pipe 301 is connected through the treatment box 302, the inner wall of the treatment box 302 is fixedly connected to a fixing plate 305, and the fixing plate 30 The top of the baking box 1 is fixedly connected with an exhaust gas purification device 306, and the top of the baking box 1 is fixedly connected with a baking mechanism 4. In this configuration, by starting the second motor 303, the second fan 304 is rotated, and the second fan 304 rotates, so that the second fan 304 sucks the exhaust gas generated when the PCB circuit board is baked into the exhaust gas suction pipe 301, and the exhaust gas flows into the processing box 302 through the airflow, so that the exhaust gas can be purified by the exhaust gas purification device 306, so as to prevent the exhaust gas generated when the PCB circuit board is baked from polluting the external environment.

[0048] Furthermore, a cooling cavity 309 is fixedly provided on the inner wall of the processing box 302, and the cooling cavity 309 cooperates with the cooling tube 201.

[0052] A baking method for a baking device for PCB processing, comprising the following steps:

[0053] Step 1: Place the PCB circuit board on the conveyor belt 110, and bake the PCB circuit board through the baking lamp tube 402 to bake and heat the PCB circuit board;

[0054] Step 2: The second motor 303 is started, and the second fan 304 is rotated by starting, so that the waste gas and heat generated when the PCB circuit board is baked are sucked into the waste gas suction pipe 301, so that the waste gas is sucked into the processing box 302, and the waste gas is purified by the waste gas purification device 306;

[0055] Step 3: The purified exhaust gas in the processing box 302 increases, the air pressure increases, and the air pressure plate 307 moves outward, and the purified gas flows into the cooling chamber 309;

[0056] Step 4: Start the first motor 203 to rotate the first fan 202 to suck the gas in the cooling chamber 309 and the cooling pipe 201 into the baking oven 1 to cool down the PCB circuit board on the baking oven 1.

[0057] Working principle: firstly, manually put the PCB circuit board from the feed port 105 onto the conveyor belt 110, and then cover the feed port 105 with the sealing plate 104 to make the internal space of the baking oven 1 sealed, and then dissipate heat energy through the baking lamp 402, so that the PCB circuit board on the conveyor belt 110 can be heated and baked, and when the sealing plate 104 and the feed port 105 are closed, the space in the baking oven 1 is a sealed space, thereby limiting the dissipation of heat energy, improving the baking effect, and thus baking the PCB circuit board dry, and when the PCB circuit board emits exhaust gas during baking, the second motor 303 is started to rotate the second fan 304, and the second fan 304 rotates, so that the second fan 304 sucks the exhaust gas generated during the baking of the PCB circuit board into the exhaust gas suction pipe 301, and the exhaust gas is discharged through the airflow. The exhaust gas is introduced into the treatment box 302 so that the exhaust gas can be purified by the exhaust gas purification device 306 to prevent the exhaust gas generated during the baking of the PCB circuit board from polluting the external environment. In addition, by providing an air pressure plate 307, when the gas purified by the exhaust gas purification device 306 increases, the air pressure in the treatment box 302 is enhanced, so that the air pressure pushes the air pressure plate 307 to move backward, so that the purified gas flows into the cooling chamber 309, and then the first motor 203 is started to rotate the first fan 202. The first fan 202 rotates to suck the gas in the cooling pipe 201 and the cooling chamber 309 into the baking oven 1. Because the first fan 202 is close to the conveyor belt 110, the blown gas cools the PCB circuit board on the conveyor belt 110 to prevent the PCB circuit board from overheating after high-temperature baking, making it impossible for the staff to take it.
