However, since most chips need to be placed on a placement board, it is inconvenient to take the chips out because the chips are in sheet form and are overall thin and fit the placement board. In view of this, we propose a chip heating and air drying box. Utility Model Content

[0006] By adopting the above technical solution: the protrusion is used to drive the push rod to move when the sealing plate rises, so that the unlocking chip and the ejecting chip can be automatically connected, which improves the degree of automation and makes it easier to take the chip.

[0007] Preferably, the upper surface of the mounting plate is fixedly connected to a connecting plate, the upper end of the connecting plate is fixedly connected to the top wall of the fixed cylinder, the lower surface of the mounting plate is rotatably connected to a driving cylinder, the outer surface of the driving cylinder is sleeved with a second reset ring, the upper side surface of the second reset ring is fixedly connected to a torsion spring, the upper end of the torsion spring is fixedly connected to the lower surface of the mounting plate, the outer surface of the driving cylinder is fixedly connected to a connecting rod, a rotating disk is provided inside the fixed cylinder, and an end of the connecting rod away from the driving cylinder is fixedly connected to the rotating disk.

[0008] By adopting the above technical solution: after the protrusion is separated from the driving cylinder, the driving cylinder can be automatically reset through the torsion spring, thereby resetting the push rod, making the upper surface of the fixed cylinder flush and preparing for the next work.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) In the chip heating and air drying box, when the chip needs to be taken after heating and drying, the driving assembly is used to drive the push rod to move in the vertical direction. When the push rod moves, the reset ring will be used to compress the spring. At the same time, the push rod will also synchronously drive the top plate to move. After the top plate moves, the chip is lifted up, which makes it easier to take the chip. The existence of the storage groove can make the upper surface of the top plate flush with the upper surface of the fixed tube during the drying process to avoid damage to the chip. Through the above structure, the chip can be taken more conveniently after drying, avoiding the situation where the chip is tightly attached to the upper surface of the placement plate, which makes it difficult to take the chip, thereby improving the practicality of the overall device.

[0013] (2) The chip heating and air drying box uses the cooperation of the protrusion and the arc groove to drive the driving cylinder to rotate. When the driving cylinder rotates, it will synchronously use the second reset ring to compress the torsion spring, and use the connecting rod to drive the rotating disk to rotate. When the rotating disk rotates, it will cooperate with the inclined groove to lift the push rod, and then lift the chip. After the chip is taken away, the driving rod descends until the protrusion is disengaged from the arc groove, and then the torsion spring and the spring are used to reset the entire device. Through the above structure, after the chip is placed, the chip can be fixed by reducing the pressure inside the fixing cylinder to prevent the chip from being blown by hot air. The chip can also be automatically lifted up when the chip is released, which is convenient for taking and does not require additional drive. BRIEF DESCRIPTION OF THE DRAWINGS

When drying, the chip is placed on the placement plate 3, and then the sealing plate 11 is driven down by the hydraulic telescopic rod 10. When the sealing plate 11 is lowered, the sealing ring 23 is used to reduce the pressure of the space above the sealing plate 11, and the chip is adsorbed on the upper surface of the fixed cylinder 4 by the through groove 5. After the drying is completed, the sealing plate 11 is reset. When resetting, the driving rod 12 is used to drive the protrusion 13 to move. After the protrusion 13 moves, it enters the interior of the arc groove 22 on the driving cylinder 16. Since the driving rod 12 cannot rotate, the driving cylinder 16 is driven by the cooperation between the protrusion 13 and the arc groove 22. When the drive cylinder 16 rotates, the second reset ring 17 will be used to compress the torsion spring 26, and the connecting rod 18 will be used to drive the rotating disk 19 to rotate.

The chip can also be automatically lifted when the fixation of the chip is released, which is convenient for taking and does not require additional drive.

After the top plate 6 moves, the chip is lifted up, which makes it easier to take the chip. The existence of the storage groove can make the upper surface of the top plate 6 flush with the upper surface of the fixed cylinder 4 during the drying process to avoid damage to the chip. When drying, the chip is placed on the placement plate 3, and then the sealing plate 11 is driven down by the hydraulic telescopic rod 10. When the sealing plate 11 is lowered, the sealing ring 23 is used to reduce the pressure in the space above the sealing plate 11, and the through groove 5 is used to adsorb the chip on the fixed cylinder 4.
