It has the following beneficial effects: By placing the semiconductor electronic device to be encapsulated in the glue application box, then outputting the required encapsulation thickness on the control panel, the electric push rod one quickly drives the scraper and the injection tube into place. Then, the motor two drives the operation plate to move, injecting glue into the semiconductor electronic device while leveling the injected glue. Finally, the motor one moves the glue application box and the semiconductor device coated with UV glue under the ultraviolet lamp. The electric push rod two drives the light-shielding cover to cover the glue application box, and then the ultraviolet lamp is turned on to cure the UV glue, preventing the ultraviolet lamp from irradiating other areas.

When the motor 7 is started, the motor 7 drives the threaded rod 5 to rotate. When the threaded rod 5 rotates, it drives the threaded cylinder 12 to move. The threaded cylinder 12 drives the fixed frame 8 to move. When the fixed frame 8 moves, the guide cylinder 13 slides on the outer wall of the guide rod 6.
[0020] The fixed frame 8 is in a square shape, and the inner end of the fixed frame 8 is elastically connected to a moving frame 9.

When the rotating roller 54 rotates, it contacts the outer wall of the moving frame 9 and pushes the moving frame 9 to one side. The moving frame 9 moves in the fixed frame 8 by squeezing or stretching the spring 1. When the rotating piece 53 does not contact the outer wall of the moving frame 9, it resets under the reaction force of the spring 1, so that the moving frame 9 drives the glue application box 18 to shake reciprocally to level the UV glue at the corners of the upper end of the semiconductor device that has not been leveled by the scraping plate 39; start the electric push rod 1 to reset the scraping plate 39 and locate it above the glue application box 18, then start the motor 1 to drive the fixed frame 8 with the glue application box 18 to move under the ultraviolet lamp 44, and then start the electric push rod 2 to drive the ultraviolet lamp 44 and the light shielding cover 50 to move down.
