[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an airbag fastening auxiliary positioning mechanism applied to an automotive rear seat side block assembly line includes a transmission mechanism 1 for conveying rear seat side blocks equipped with airbags. The transmission mechanism 1 can smoothly and continuously convey the rear seat side blocks equipped with airbags. The transmission mechanism 1 ensures a smooth and efficient assembly process. An auxiliary fastening device 2 is provided on one side of the transmission mechanism 1 for fixing the airbag's position on the rear seat side block. The auxiliary fastening device 2 achieves precise control over the airbag's position on the rear seat side block.

[0026] The auxiliary fastening device 2 includes a fixed frame 3 set on one side of the transmission mechanism 1. The fixed frame 3 is equipped with a horizontal positioning mechanism 4, a downward positioning mechanism 5 and a bolt positioning mechanism 6. The horizontal positioning mechanism 4 is used to horizontally press the edge fabric of the airbag onto the side block of the car rear seat. The horizontal positioning mechanism 4 can make fine adjustments according to the thickness and shape of the edge fabric of the airbag. Through horizontal thrust, the edge fabric of the airbag is evenly and tightly attached to the side block of the car rear seat to prevent displacement or wrinkles in subsequent processes.

[0027] The downward positioning mechanism 5 is used to vertically press the edge fabric of the airbag onto the side block of the rear seat of the car; the downward positioning mechanism 5 further compacts the edge fabric of the airbag through vertical pressure to ensure its stability during the assembly process.

[0028] The bolt positioning mechanism 6 is used to align the bolt shank of the airbag with the bolt holes on the rear seat side panel of the vehicle and facilitate the installation of the nut. The bolt positioning mechanism 6 ensures precise alignment between the airbag bolt shank and the bolt holes on the rear seat side panel. Simultaneously, the bolt positioning mechanism 6 is also equipped with auxiliary installation tools, such as an automatic nut feeder and a rotary tightening device, which greatly simplifies the bolt installation process and improves assembly efficiency and accuracy.

[0029] This airbag fastening auxiliary positioning mechanism, through its integrated design, organically combines multiple processes such as transmission, positioning, and fastening. It not only significantly improves the automation level of the rear seat side assembly line, but also effectively ensures the accuracy and safety of airbag installation, providing strong support for quality control and production efficiency improvement in the automotive manufacturing industry.

[0030] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the horizontal positioning mechanism 4 includes a first cylinder 41 mounted on the fixed frame 3. By controlling the extension and retraction of the cylinder, precise movement control of the movable frame 42 and its positioning push block 43 can be achieved.

[0031] The output end of the first cylinder 41 is connected to a movable frame 42, which ensures rapid and smooth movement under the push of the cylinder. A positioning push block 43 is mounted on the movable frame 42. The positioning push block 43 acts directly on the edge fabric of the airbag to achieve horizontal compression. The shape and size of the positioning push block 43 are customized according to the characteristics of the edge fabric of the airbag to ensure optimal compression and minimal material damage.

[0032] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a fixed slide rail 31 is provided on the top of the fixed frame 3, and a fixed slider 421 matching the fixed slide rail 31 is provided on the bottom of the movable frame 42. In order to ensure that the movable frame 42 can move smoothly and accurately in a straight line along the fixed frame 3, the movable frame 42 can achieve precise horizontal movement under the push of the cylinder through the cooperation of the fixed slide rail 31 and the fixed slider 421, thereby achieving precise positioning and pressing of the fabric at the edge of the airbag.

[0033] Combination Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the pressing and positioning mechanism 5 includes a second cylinder 51 mounted on the movable frame 42.

A mounting plate 52 is connected to the output end of the second cylinder 51, acting as a bridge connecting the second cylinder 51 and the third cylinder 53. The mounting plate 52 can withstand the enormous force generated by the movement of the second cylinder 51 and ensures the stability and reliability of the entire pressing and positioning mechanism 5.

[0034] A third cylinder 53 is mounted on the mounting plate 52. The output end of the third cylinder 53 is connected to a lower pressure plate 54. The third cylinder 53 is mounted on the mounting plate 52, and through the extension and retraction of its output end, it achieves precise control of the lower pressure plate 54. The third cylinder 53 also has the characteristics of fast response and stable output, which can ensure that the lower pressure plate 54 vertically presses the fabric at the edge of the airbag with appropriate speed and force.

[0035] A pressure roller 55 is installed at the bottom of the pressure plate 54. In order to reduce the friction and damage of the pressure plate 54 to the edge fabric of the airbag, the pressure roller 55 is installed at the bottom of the pressure plate 54. The pressure roller 55 can roll and evenly distribute the pressure during the pressing process, thereby achieving a gentle and uniform pressing of the edge fabric of the airbag.
