Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing technology, and more specifically, to a hot air gun accessory for disassembling components. Background Technology

[0002] In the process of repairing electronic products, disassembling components is a very common operation, and care must be taken to avoid damaging other components during disassembly. Currently, for multi-pin components, the common method is to use a soldering iron to melt the solder on the pins and then remove the component with tweezers, or to use a hot air gun to melt the solder joints and then remove the component with tweezers. For through-hole components, the common method is to use a desoldering gun to remove the solder from the pins and then remove the component, or to use a hot air gun to melt the solder joints and then remove the component with tweezers.

[0003] When using a hot air gun to remove components, high-temperature tape is needed to protect surrounding components and isolate the components being removed, which can sometimes make it inconvenient to use tweezers to remove components. When using a soldering iron to remove components, it is necessary to melt the solder at multiple solder joints at the same time, which is difficult and inefficient. When using a desoldering gun to remove through-hole components, it is easy to cause the solder pads to lift or fall off.

[0004] Therefore, there is an urgent need to study a component removal device that does not require tweezers or soldering irons to melt solder, and that does not come into contact with the solder pads and surrounding components when removing components. Utility Model Content

[0007] The heat gun has an ellipsoidal upper part and a cylindrical lower part. The lower part is connected to one end of the upper part. The air outlet is located at the end of the upper part of the heat gun that is away from the lower part. The lower part of the heat gun is used for holding.

[0008] The nozzle is located at the air outlet on the upper part of the hot air gun and is fixed to the hot air gun through the nozzle support bracket. The nozzle support bracket is fixed to the hot air gun through the nozzle support bracket fixing piece.

[0009] The nozzle support frame is conical in shape with a support rod in the center. The nozzle is fixed to the top of the cone and the support rod is used to fix the nozzle at the top. The support rod extends into the hot air gun and is fixedly connected. The negative pressure delivery pipe is set at the nozzle support frame to extend from the bottom of the cone along the inclined surface to the top of the nozzle support frame.

[0010] The nozzle support bracket is a ring-shaped fastener that secures the bottom of the nozzle support bracket to the air outlet of the hot air gun.

[0013] The negative pressure controller is used to control the amount of negative pressure generated by the vacuum generator. One end is connected to the vacuum generator, and the other end is connected to the suction nozzle through the negative pressure delivery pipe.

[0014] The hot air gun melts the solder joints of the components to be disassembled with hot air. The suction nozzle is placed close to the components to be disassembled, and the negative pressure is introduced by manually switching the negative pressure controller to suck up the components, thus achieving the disassembly of the components.

The hot air gun is then moved to remove the component, and the negative pressure is turned off to remove the component.

[0043] This accessory is used to remove surface-mount and through-hole components from a printed circuit board (PCBA).

[0044] In summary, the embodiments of this specification provide a hot air gun accessory for disassembling components.
