A servo motor 3 is fixedly connected to one corner of the bottom end of the conveyor frame 7. The servo motor 3 is fixedly connected to one of the sets of corner wheels 8. A moving groove 13 is opened inside the conveyor frame 7 along its length direction. A movable moving seat 11 is embedded in the moving groove 13. A set of rotatable moving wheels 10 is installed on each side of the moving seat 11. A transmission belt 9 is connected between the moving wheels 10 and the corner wheels 8. A set of fixing frames 12 are installed at each end of the moving seat 11. The fixing frames 12 are metal rods and are symmetrically distributed about the horizontal center line of the conveyor frame 7.

[0021] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the device uses a transmission belt 9 in conjunction with corner wheels 8 and movable wheels 10 to form a transmission. The corner wheels 8 are driven to rotate by a servo motor 3, which in turn drives a set of movable wheels 10 at the movable seat 11 to rotate via the transmission belt 9. The other set of movable wheels 10 rotates in the same direction under the rotation of the corner wheels 8, thereby driving the movable seat 11 to move on the surface of the movable groove 13 from the outside to the inside of the dryer 1, and sending the circuit board placed on the fixed frame 12 into the drying zone 14 for drying.

At the same time, the temperature can be controlled in zones to dry circuit boards of different sizes.

[0026] Working principle: The circuit board is placed on the support plate 18. The lever 15 is moved, and the distance between the two sets of support plates 18 is adjusted by the movement of the adjustment frame 16 in the adjustment groove 17 to adapt to the size of the circuit board, thereby supporting and clamping the circuit board. The dryer 1 adopts a zoned drying design. Several electric heating tubes 4 are set in the drying zone 14. Each set of fixed frame 12 sends a set of circuit boards into a set of drying zones 14. During drying, the airflow converges at the location of the circuit board, reducing heat loss. At the same time, the temperature can be controlled in zones. The device uses a transmission belt 9 in conjunction with corner wheels 8 and moving wheels 10 to form a transmission. The corner wheels 8 are driven to rotate by the servo motor 3, which in turn drives a set of moving wheels 10 at the moving seat 11 to rotate through the transmission belt 9. The other set of moving wheels 10 rotates in the same direction under the rotation of the corner wheels 8, thereby driving the moving seat 11 to move on the surface of the moving groove 13 from the outside into the dryer 1, sending the circuit board placed on the fixed frame 12 into the drying zone 14 for drying.
