Abstract

The present application is applicable to the field of material making, and there is provided a baking method, device and baking oven including: acquiring a predetermined instruction, and starting timing and cycling the following steps: controlling a first set of pins to support a substrate from an initial position and recording the rising times of the first set of pins; raising the first set of pins to a first preset position, and controlling the first set of pins to move a first preset distance in a first preset direction, wherein the first preset distance is associated with the rising times of the first set of pins; controlling the lowering of the first set of pins such that a second set of pins supports the substrate; and controlling the first set of pins to return to the initial position, when the first set of pins drops to a second preset position.

First claim

What is claimed is:

1. A baking method comprising the steps of:
acquiring a predetermined instruction, and starting timing and cycling the following steps:
controlling a first set of pins to support a substrate from an initial position and recording rising times of the first set of pins;
raising the first set of pins to a first preset position, and controlling the first set of pins to move a first preset distance in a first preset direction, such that the substrate moves the first preset distance in the first preset direction, wherein the first preset distance is associated with the rising times of the first set of pins;
controlling a lowering of the first set of pins such that a second set of pins supports the substrate; and
controlling the first set of pins to return to the initial position, when the first set of pins drops to a second preset position.

2. The baking method according to claim 1 , wherein the predetermined instruction refers to an instruction of start baking, and the starting timing refers to start timing when acquired the instruction of start baking.

3. The baking method according to claim 1 , wherein a distance of the first set of pins raising from the initial position to the first preset position is equal to a dropping distance of the first set of pins dropping from the first preset position to the second preset position.

4. The baking method according to claim 1 , wherein after the first set of pins returning to the initial position, the method further comprises:
acquiring a time record, when the time record is equal to or greater than a preset time, resetting the time record and the rising times of the first set of pins to an initial value, and restarting timing and cyclically performing the following steps:
controlling the first set of pins to support the substrate from the initial position and recording the rising times of the first set of pins;
raising the first set of pins to the first preset position, and controlling the first set of pins to move a second preset distance in a second preset direction, such that the substrate moves the second preset distance in the second preset direction, wherein the second preset distance is associated with the rising times of the first set of pins;
controlling the lowering of the first set of pins such that the second set of pins supports the substrate;
controlling the first set of pins to return to the initial position, when the first set of pins drops to the second preset position;
acquiring the time record, and discharging the substrate when the time record is equal to or greater than the preset time.

5. The baking method according to claim 4 , wherein the initial value being 0 and the second preset distance associated with the rising times of the first set of pins is:
R i =x ,( i= 1)
R i =2 x ,( i= 2,3,4, . . . )
wherein R i represents the second preset distance, and i represents the rising times of the first set of pins.

6. The baking method according to claim 4 , wherein the preset time is ½ of a baking time.

7. The baking method according to claim 1 , wherein the first preset distance associated with the rising times of the first set of pins is:
L i =x ,( i= 1)
L i =2 x ,( i= 2,3,4, . . . )
wherein L i represents the first preset distance, and i represents the rising times of the first set of pins.
