[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the semiconductor packaging process, when the plastic encapsulation process product is completed after molding, when the flow channel waste glue process is carried out, if there is resin debris that is not cleaned up and remains in the flow channel, it will cause abnormal packaging colloid collapse, such as colloid corner collapse, corner chipping, and exposed substrate, which will affect the product appearance and cause product reliability failure, thereby increasing the defective rate of semiconductor products. Based on the above explanation, the solution is to use air blowing to clean the glue residue or glue chips scattered in the flow channel out of the flow channel. The specific solution based on this idea is an air blowing device, such as Figures 1-4 As shown, it is provided with an operating end head 1, which provides an installation basis for the structure subsequently installed thereon to produce a blowing function, and the operating end head 1 is installed on one end of the flow channel machine to produce an effect thereon, and the operating end head 1 is provided with a blowing head 2 for blowing air toward the flow channel machine, and the operating end head 1 is provided with a lifting member 3 acting on the blowing head 2 to drive it to move up and down, and the blowing head 2 is provided with an angle adjustment member 4 to achieve multi-angle blowing, and the combination of the lifting member 3 and the angle adjustment member 4 is utilized to adjust the height and angle of the blowing base 21 used for blowing air into the flow channel, so that the blowing surface of the resin chips in the flow channel is formed on the arc surface, thereby increasing the intensity and area of ​​action on the resin chips, and further improving the cleanliness of the flow channel.

[0026] The blowing head 2 includes two blowing bases 21 symmetrically mounted on the working end 1. The blowing base 21 is provided with a blowing hole 22 relative to the flow channel machine. The rear end of the working end 1 is connected to an air inlet pipe 5 for supplying air to the blowing hole 22. The two blowing bases 21 are connected by a connecting plate 23 and synchronize the lifting member 3 to move up and down. The angle adjustment member 4 is installed on the two blowing bases 21 to control the adjustment angle relative to the flow channel machine. It includes a central axis 41 that horizontally passes through the blowing end seat and is connected to the synchronization shaft 31. The connection between the central axis 41 and the synchronization shaft 31 forms a connection basis with the lifting member 3, so that the lifting member 3 can follow the movement. The central axis 41 is rigidly connected to the blowing end seat, so that when the central axis 41 rotates, the blowing end seat generates the same rotation angle. Based on this, the installation position of the central axis 41 coincides with the symmetrical center line of the blowing end seat. The central axis 41 passes through the side plate 12 and extends to its outside, extending A backing plate 42 is rotatably sleeved on the central axis 41 structure outside the side panel 12. A protrusion 44 is mounted on one end of the backing plate 42, which is in contact with the side panel 12. The protrusion 44 slides on the side panel 12 to guide the follow-up movement of the central axis 41. The protrusion 44, which is located in the sliding groove 15 on the backing plate 42, provides a guide during the follow-up movement of the central axis 41, ensuring that it always remains on the center line of the blowing base 21. This improves the control accuracy of the synchronous drive of the blowing base 21 by the central axis 41 when it rotates. A manual knob 43 is connected to one end of the backing plate 42, which is rigidly connected to the central axis 41. When the angle of the blowing tip needs to be adjusted, the manual knob 43 is turned to rotate the central axis 41, thereby driving the angle of the blowing tip and, at the same time, adjusting the blast direction on a fan-shaped surface.

[0027] The working end 1 is frame-shaped and specifically comprises a bottom plate 11 and side plates 12 mounted on both ends of the bottom plate 11. The side plates 12 are provided with a through slot 14 adapted to the diameter of the central axis 41. Strip grooves 15 are provided at both ends of the through slot 14, adapted to the protrusions 44, and the depth of the strip grooves 15 is less than the depth of the through slot 14. The upper ends of the two side plates 12 are connected to a top plate 13 provided with a drive device, specifically a drive motor. The lifting member 3 is coaxially connected to the drive device and extends longitudinally to connect with the connecting plate 23. The lifting member 3 includes a synchronous shaft 31 connected to the connecting plate 23. A threaded rod 32 is connected to the thread of the synchronous shaft 31. After the drive motor is driven by the controller and outputs torque, the synchronous shaft 31 drives the central axis 41 to which it is connected to move, thereby creating the effect of the blowing head 2 rising or falling as a whole.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
