DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Reference Figures 1 to 4A circuit board dispensing and drying device for microelectronic processing includes a base plate 1, two first support plates 2 and a second support plate 3 arranged perpendicularly to the base plate 1, and two first through slots 4.

[0023] In the above embodiment, the base plate 1 serves as the supporting foundation of the microelectronics processing circuit board dispensing and drying device. It can be made of manganese steel to provide sufficient support for the microelectronics processing circuit board dispensing and drying device, extend its service life, and reduce subsequent maintenance costs. Two first support plates 2 are welded to both sides of the base plate 1, and a second support plate 3 is welded between the first support plates 2. The first support plates 2 and the second support plates 3 can be made of silicate material and are welded to corresponding parts by argon welding. This can effectively isolate the heat emitted by the baking lamp 5 and prevent the heat from harming the human body. Two first through slots 4 are respectively opened on both sides of the second support plate 3 to restrict the movement direction of subsequent parts.

[0024] It includes nine heat lamps 5, a storage battery 6, a temperature sensor 7, and a microcontroller 8.

[0025] Preferably, all nine heat lamps 5 are installed between the first support plates 2. The heat emitted by the heat lamps 5 dries the glued circuit board, ensuring that the glue on the circuit board is heated evenly without shifting its position, thus improving the drying effect. The battery 6 is attached to the top of the second support plate 3 to provide power for the heat lamps 5. The temperature sensor 7 is fixed to one side of the first support plate 2 with screws to monitor the temperature emitted by the heat lamps 5 in real time. The temperature sensor 7 transmits the information to the microcontroller 8 by setting a threshold. The microcontroller 8 is fixed to the second support plate 2 with screws. At the top of the support plate 3, the microcontroller 8 processes the signal emitted by the temperature sensor 7, and then controls the discharge level of the battery 6 to the heat lamp 5 through the signal. The temperature sensor 7 is electrically connected to the microcontroller 8, the microcontroller 8 is electrically connected to the battery 6, and the battery 6 is electrically connected to the heat lamp 5. By setting the threshold of the temperature sensor 7, the microcontroller 8 controls the battery 6 to discharge to the heat lamp 5. When a certain temperature is reached, the temperature sensor 7 transmits a signal to the microcontroller 8, and the microcontroller 8 controls the battery 6 to reduce the discharge level of the heat lamp 5, so that the heat lamp 5 emits stable heat and ensures that the circuit board is heated evenly.

[0026] First, refer to Figure 2 In this embodiment, it also includes three support blocks 9, a conveyor belt 10, and a first motor 11.

[0027] Three support blocks 9 are welded to the top of the base plate 1 to fix the position of the conveyor belt 10. The conveyor belt 10 is fixed between the support blocks 9 and is used to drive the circuit board into the heat dissipation area of ​​the baking lamp 5 for drying the glue application position. The first motor 11 is fixed to the base plate 1 with screws. The output shaft of the first motor 11 is connected to the drive shaft of the conveyor belt 10 by a key. The first motor 11 drives the conveyor belt 10 to move, thereby realizing the transfer of the circuit board.

[0028] Then, refer to Figure 2 In this embodiment, a support frame 12 and a first through hole 13 are also included.

[0029] The support frame 12 is welded to the top of the base plate 1 to serve as the load-bearing foundation for subsequent parts, and the first through hole 13 is opened on the top of the support frame 12.

[0030] Secondly, see Figure 2 and Figure 3 In this embodiment, it also includes a first screw 14, a second motor 15, a first connecting plate 16, a threaded hole 17, and two second connecting plates 18.

[0031] One end of the first screw 14 is rotatably mounted on the top of the second support plate 3. Rotating the first screw 14 drives the first connecting plate 16, which is threadedly connected to it, to move. The second motor 15 is fixed to the top of the second support plate 3 with screws. The other end of the first screw 14 is keyed to the output shaft of the second motor 15. The first motor 11 serves as the power source. Rotating the output shaft of the first motor 11 drives the first screw 14 to rotate, thereby moving the first connecting plate 16. The first connecting plate 16 is threaded onto the first screw 14, and a threaded hole 17 is formed in the middle of the first connecting plate 16. Rotation of the first screw 14 drives the first connecting plate 16 to move, thus achieving... The two second connecting plates 18 on both sides slide within the first through groove 4, which can be adjusted according to the thickness of the circuit board to reduce internal heat loss and waste of resources, and make full use of the heat emitted by the heat lamp 5. The two second connecting plates 18 are respectively welded to both ends of the first connecting plate 16. Both second connecting plates 18 are made of silicate material and are welded to both ends of the first connecting plate 16 by argon welding, which effectively isolates internal heat and reduces internal heat loss. The two second connecting plates 18 are slidably set in the first through groove 4. The first through groove 4 and the second connecting plates 18 are tightly slidably connected, which can limit the sliding direction of the second connecting plates 18 while reducing internal heat loss.

[0032] Working principle:

[0033] In use, the microelectronics processing circuit board dispensing and drying device is first placed in the desired location. Then, when drying the circuit board after dispensing, the specific operation is as follows: First, the operator turns on the first motor 11 and adjusts it to a suitable speed to drive the conveyor belt 10 to rotate. Then, the operator turns on the second motor 15. The output shaft of the second motor 15 drives the first screw 14 to rotate. The first screw 14 drives the first connecting plate 16 to move, and the movement of the first connecting plate 16 causes the second connecting plate 18 to slide within the first through groove 4. When the second connecting plate 18 reaches the appropriate position, the second motor 15 is turned off. At this time, the temperature sensor 7 has not reached the signal threshold and thus transmits a signal to the microcontroller 8. The microcontroller 8 controls the battery 6 to discharge to the baking lamp 5, and the baking lamp 5 heats up, thereby heating the cavity formed between the first connecting plate 16, the first support plate 2, and the second support plate 3. When the temperature reaches the threshold of the temperature sensor 7, the microcontroller 8 reduces the discharge of the battery 6 to the baking lamp 5, so that the temperature inside the cavity is kept stable at a suitable temperature for drying the circuit board. Then the circuit board is placed on the conveyor belt 10 and driven into the cavity by the first motor 11, thereby achieving the drying of the circuit board.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
