[0009] The circuit boards are placed on the left conveying mechanism one by one, and the two rotating shafts are driven to rotate clockwise. When the left conveying mechanism carrying the circuit boards moves close to the chain, the support rods on the left side of the chain move upward with the rotation of the chain. The support rods support the circuit boards upward, so that the front and back surfaces of the circuit boards are in contact with air and heat exchange occurs, thereby cooling the circuit boards. At the same time, the air blower is driven to work, so that the air blower sends the cold air below the bellows into the inner cavity and out through the air outlets. The front and back surfaces of the circuit boards are continuously blown during the rotation of the circuit boards with the chain. When the circuit boards rotate to the right side of the chain, the support rods on the right side of the chain support the circuit boards to move downward until the bottom of the circuit boards contacts the right conveying mechanism. The right conveying mechanism carries the next circuit board away from the turnover mechanism during the downward movement of the circuit board.

A through hole is formed in the top of the inner side wall of the outer cover and extends to the outer side wall of the outer cover. An air extractor is fixedly arranged in the through hole.

[0016] The principle and effects of the technical scheme are as follows:

[0017] The air blown out by the bellows becomes hot air after heat exchange with the circuit boards. The air extractor is started to extract the hot air in the outer cover.

[0018] Through the above arrangement, the hot air in the outer cover can be timely discharged, and the cooling effect of the circuit boards is further improved.

[0019] In the utility model, the upper portion of the operation platform is fixedly provided with a motor, and one of the rotating shafts is in transmission connection with the output shaft of the motor.

[0020] In the utility model, the outer side wall of the supporting rod is fixedly provided with a plurality of anti-skid rubber pads. BRIEF DESCRIPTION OF DRAWINGS
