The warming device 83 is combined with the blowing device 82 to realize indoor circulating blowing, so that heat can be fully diffused to all areas of the multi-layer shelf 54. In addition, a waste gas exhaust pipe 84 is respectively arranged at the feed port 11 and the discharge port 11.
The centering plate arranging device 90 includes a programmable motor 91, a centering transmission device 92 and two centering execution devices 93, the centering transmission device 92 is installed between the material lifting and conveying device 50 and the material falling and conveying device 60, the centering transmission device 92 includes two centering transmission gears 921 and a centering transmission chain 922 sleeved on the two centering transmission gears 921, and the programmable motor 91 is sleeved on one centering transmission chain 922 through a belt to drive the centering transmission chain 922 to rotate. Execute device 93 placed in the middle includes mount pad 931 and sets up the board 932 placed in the middle in the mount pad 931 top, and the mount pad 931 on two execute device 93 placed in the middle installs in the transmission chain 922 placed in the middle of the both sides of drive gear 921 respectively to, when drive gear 921 placed in the middle drives transmission chain 922 placed in the middle and removes, two are placed in the middle board 932 and can be close to in opposite directions or keep away from in opposite directions, thereby center circuit board 100, in order to avoid circuit board 100 to be partial to when the blanking conveying, lead to falling the problem of board.
When the circuit board 100 is sensed by the sensing device on the feeding device 30, the sensing device transmits a signal to the position correcting device 40, the two position correcting plates 46 driven by the position correcting driver 41 move inwards at the same time to correct the position of the circuit board 100, and after the position correction is completed, the two position correcting plates 46 move away in the opposite direction. The circuit board 100 continues to move into the feeding hole 11, and at the same time, the material pushing plate 31 will move with the feeding device 30 and push the circuit board 100 forward to two carrying plates mounted on the same layer of the adjacent multi-layer rack 54 of the material lifting and conveying device 50.
The worm driving device 53 drives the worm 52 to rotate, the worm 52 drives the bearing plates 542 of the two multi-layer frames 54 of the lifting and conveying device 50 to simultaneously lift the circuit board 100 to rise by one layer, and then the rear circuit board 100 on the feeding device 30 is pushed onto the bearing plates 542; this is repeated until the first circuit board 100 reaches the uppermost position of the raising conveyor 50. Then, the material pushing device 70 pushes the circuit board 100 at the top to the topmost layer of the blanking and conveying device 60, and the board arranging device 90 arranged in the middle arranges the circuit board 100 in the middle to avoid the deviation of the circuit board 100 entering the blanking and conveying device 60. The blanking conveying device 60 drives the circuit board 100 to descend gradually, when the first circuit board 100 reaches the feeding device 30, the two supporting plates 542 rotate away from the two sides of the feeding device 30, the circuit board 100 falls on the feeding device 30 again, and the feeding device 30 sends out the circuit board 100. Therefore, in the whole feeding process, one circuit board enters from the feeding hole 11, and the other baked circuit board is discharged from the discharging hole 12. While the other circuit boards 100 are baked while being conveyed on the material lifting and conveying device 50 and the material dropping and conveying device 60; the transfer time can be set according to the required baking time.
In conclusion, the multi-layer lifting conveying device is arranged, so that the working efficiency and the occupied space area of the conveying device are greatly improved; and the full and effective utilization of heat is realized. In addition, the rotary blowing device of the air conveying device 80 and the bearing plate 542 are assembled by rods, so that the heat circulation utilization rate is greatly improved. The invention has strong practicability and stronger popularization significance.
