[0030] Welding structure 6 includes a lifting plate 601. A positioning strip 612 is provided on the outer wall of the lifting plate 601. An installation groove 603 is formed inside the positioning strip 612. A rotating strip 602 is rotatably connected to one end of the positioning strip 612. A welding gun body 604 is provided at one end of the rotating strip 602. A pull rod 605 is provided at the top of the rotating strip 602. Multiple rotating strips 602 are arranged in a circular array on the outer wall of the lifting plate 601. A slider 606 is provided at the top of the pull rod 605. A meshing gear 6 is rotatably connected to one side of the top of the lifting plate 601. 08. A rotating disk 609 is rotatably connected to the top of the lifting plate 601. An internal gear ring 610 is provided on the inner side of the rotating disk 609. A pushing block 611 is provided on the outer wall of the internal gear ring 610. The internal gear ring 610 meshes with a meshing gear 608. The pushing block 611 is slidably connected to a pull rod 605. The slider 606 is slidably connected to an auxiliary groove 505. A return spring 607 is provided between the slider 606 and the auxiliary groove 505. The rotating bar 602 can rotate inward and outward, so that the rotating bar 602 can be aligned with the connection position of the second interior trim 3 and the first interior trim 2 of different sizes.

[0031] Furthermore, the interior decoration placement structure 1 includes a housing 101, a first bracket 102 is provided on the top of the housing 101, a second bracket 103 is provided on the top of the first bracket 102, a servo motor 104 is provided on one side of the top of the second bracket 103, and a drive gear 105 is provided at the output end of the servo motor 104. The first interior decoration 2 is placed inside the housing 101, and then the second interior decoration 3 is inserted into the first interior decoration 2 to pre-fix the position of the first interior decoration 2, thereby maintaining the stability of the first interior decoration 2 and the second interior decoration 3 during the welding process.

[0032] Furthermore, the guide structure 5 includes a drive shaft 501, with guide grooves 502 on both sides of the outer wall of the drive shaft 501. A driven gear 503 is provided on the outer wall of the drive shaft 501, and the driven gear 503 is slidably connected to the drive shaft 501 through the guide grooves 502. The driven gear 503 meshes with the driving gear 105. A side plate 504 is provided on the outer wall at the bottom of the drive shaft 501, and an auxiliary groove 505 is provided at the bottom of the side plate 504. The number of auxiliary grooves 505 is set to multiple. (The last sentence appears to be incomplete and possibly refers to starting a servo motor.) 104. Servo motor 104 drives drive gear 105 to rotate, drive gear 105 drives driven gear 503 to rotate, driven gear 503 drives drive shaft 501 to rotate, and then drive shaft 501 rotates the bottom welding structure 6, so that welding structure 6 can rotate to weld the connection position of the first interior 2 and the second interior 3. At the same time, electric telescopic rod 4 is activated, electric telescopic rod 4 drives drive shaft 501 to slide vertically inside driven gear 503, so that drive shaft 501 can also drive welding structure 6 to rise and fall.

[0033] In this embodiment, when welding is required on the automotive interior, the first interior trim 2 and the second interior trim 3 are placed inside the housing 101. Then, the motor is started, and the motor drives the meshing gear 608 to rotate. The meshing gear 608 drives the rotating disk 609 to rotate through the internal gear ring 610. The rotating disk 609 drives the push block 611 to rotate. Then, the push block 611 pushes the pull rod 605 to rotate, and the slider 606 slides on the inner wall of the auxiliary groove 505 and stretches the return spring 607. The slider 606 is set to be spherical, so that the slider 606 can slide inside the auxiliary groove 505 and rotate inside the auxiliary groove 505 at the same time. During the rotation, the slider 606 drives the rotating bar 602 to rotate, so that the rotating bar 602 drives the welding gun body 604 at the front end to align with the connection position of the second interior trim 3 and the first interior trim 2.

[0034] Then, the electric telescopic rod 4 is activated, which pushes the guide structure 5 to move downward. The guide structure 5 drives the welding structure 6 to move downward, so that the welding gun body 604 inside the welding structure 6 is aligned with the connection position of the first interior 2 and the second interior 3, and the connection position of the first interior 2 and the second interior 3 is welded.

[0035] The servo motor 104 is started, which drives the drive gear 105 to rotate. The drive gear 105 drives the transmission shaft 501 to rotate through the driven gear 503. The transmission shaft 501 is rotatably connected to the output end of the electric telescopic rod 4. Then, the transmission shaft 501 drives the welding structure 6 to rotate. The welding structure 6 drives the welding gun body 604 inside to perform rotational welding on the connection position of the first interior trim 2 and the second interior trim 3.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
