[0024] See Figure 1 and Figure 2 As shown, it also includes a glass window 29, which is embedded in the soundproof door 15.

[0025] When using this device, first place the door interior panel and map bag on the mounting plate 5, align the ultrasonic welding gun 11 with the welding area of ​​the door interior panel and map bag, and then start the servo motor 16. The output shaft of the servo motor 16 drives the bidirectional screw 17 to rotate. The bidirectional screw 17 drives the soundproof doors 15 on both sides to move synchronously along the second guide rod 18. During welding, they close to form a sealed space, which can effectively block ultrasonic noise and prevent small particles from flying out due to material deformation caused by heat from injuring the operator. After the soundproof doors 15 are closed, start the hydraulic press 7.
