Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] In this embodiment, by Figure 1-4 The present invention includes an outer shell 1, a furnace door 2 located in the middle of one side wall of the outer shell 1, a transparent window 3 located in the middle of the furnace door 2, a fixing plate 4 located on the upper part of one side wall of the outer shell 1, an electric push rod 5 located near the upper middle of the fixing plate 4, a top cover 6 located at the output end of the electric push rod 5, a frame 7 located around the top cover 6, a pad 8 located on the inner wall of the frame 7, a first heat insulation plate 9 connected to the lower end of the top cover 6 by bolts, a second heat insulation plate 10 located on the inner wall of the outer shell 1, electric heating rods 11 located on both inner walls of the second heat insulation plate 10, and a temperature sensor 12 located at the lower end of the second heat insulation plate 10 located at the top inner end of the outer shell 1.
[0021] The furnace door 2 is connected to the outer shell 1 by a hinge. The furnace door 2 is bonded with a heat insulation layer. After the furnace door 2 is opened, the chip to be preheated can be placed at the bottom of the preheating furnace. Then the furnace door 2 is closed. The transparent window 3 is embedded in the middle of the furnace door 2. The transparent window 3 is made of high temperature resistant tempered glass. The fixing plate 4 is connected to the side wall of the outer shell 1 by bolts. The transparent window 3 allows for easy observation of the preheating furnace from the outside.
[0022] Among them, the electric push rod 5 is connected to the fixed plate 4 by bolts, and the transmission output end of the electric push rod 5 is connected to the side wall of the top cover 6 by bolts. When working, the electric push rod 5 can drive the top cover 6 to move laterally. Side plates 13 are formed on both sides of the top cover 6. The lower end of the first heat insulation plate 9 is slidably connected to the upper end of the outer shell 1. The top cover 6 is slidably connected to the inner wall of the gasket 8. The lower end of the frame 7 is welded to the upper end of the outer shell 1. The gasket 8 can ensure the sealing between the top cover 6 and the frame 7. When the top cover 6 is closed, the first heat insulation plate 9 and the second heat insulation plate 10 can ensure the heat preservation performance of the preheating furnace.
[0023] The second heat insulation plate 10 is bonded to the inner wall of the outer shell 1, the electric heating rod 11 is connected to the second heat insulation plate 10 by bolts, and the temperature sensor 12 is connected to the second heat insulation plate 10 by screws. When working, the electric heating rod 11 can heat the preheating furnace, and the temperature sensor 12 can sense the temperature inside the preheating furnace in real time and feed the sensed information back to the external control equipment of the preheating furnace.
[0024] Working principle: The preheating furnace uses an external power supply and is controlled by an external control device. When the chip is processed in the preheating furnace, the furnace door 2 can be opened and the chip placed in the middle of the bottom of the preheating furnace. Alternatively, the top cover 6 can be opened so that the chip transfer robot can place the chip from the top of the preheating furnace to the middle of the bottom of the preheating furnace. Then, the furnace door 2 or the top cover 6 is closed, and the heating rod 11 is controlled to work, so that the temperature inside the preheating furnace gradually rises. The temperature sensor 12 can sense the temperature inside the preheating furnace in real time and feed back the sensing information to the external control device of the preheating furnace. This makes it easy to control the temperature of the preheating furnace. After the chip preheating is completed, the electric push rod 5 can be controlled to open the top cover 6, and then the chip transfer robot can enter the preheating furnace from the top and take out the chip. The transparent window 3 allows for easy observation of the situation inside the preheating furnace from the outside, as well as the operation of the chip transfer robot inside the preheating furnace.
