[0043] The structure of the side curtain air curtain installation device of this utility model is further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments are not intended to limit the scope of protection of this utility model.

[0044] This utility model provides a side curtain air wrapping installation device, which is usually set on a working platform 1 and includes an angle adjustment mechanism 2; Figure 1 This is a schematic diagram of the angle adjustment mechanism of the side curtain air curtain installation device according to an embodiment of the present invention. Specifically, the angle adjustment mechanism 2 includes a support column 21 and a rotating assembly; the rotating assembly includes a base 22, a rotating seat ring 23 and at least one metal detector 24 arranged coaxially; the base 22 is fixed to the top of the support column 21 and has a first through hole 221 at its center; the rotating seat ring 23 is rotatably nested in the first through hole 221 of the base 22, and has at least one metal sensing element 231 distributed on its outer periphery, and the rotating seat ring 23 has a second through hole 232.

[0045] The first clamping mechanism includes a driven rotary seat 25, a connecting plate 26, and a gripper unit. The driven rotary seat 25 is mechanically coupled to the rotary seat ring 23 and rotates synchronously. Figure 2 This is an exploded view of the angle adjustment mechanism of a side curtain air covering installation device according to one embodiment. The rotating seat ring 23 is provided with an arc-shaped limiting groove (not shown in the figure), the central axis of which coincides with the central axis of the rotating seat ring 23. The driven rotating seat 25 is provided with a third through hole 251. The first through hole 221, the second through hole 232, and the third through hole 251 are coaxial, and a sleeve of the side curtain air covering installation device can be accommodated therein.

[0046] Figure 2 The angle adjustment mechanism of this embodiment includes a fixed rod 223 and at least one connecting rod (not shown in the figure). The fixed rod 223 passes through the limiting groove and connects to the base 22. The connecting rod passes through the base 22 and connects the rotating seat ring 23 and the driven rotating seat 25, so that when the rotating seat ring 23 rotates, it drives the driven rotating seat 25 to rotate. During the rotation of the rotating seat ring 23, the arc-shaped limiting groove slides along the fixed rod 223, forming the rotation of the rotating seat ring 23. The rotation angle of the rotating seat ring 23 is limited by the trajectory range of the arc-shaped groove. That is, the fixed rod 223 limits the movement range of the arc-shaped limiting groove, which can be two or more, and is not limited here. The fixed rods at both ends determine the movement range of the limiting groove, that is, determine the rotation angle of the rotating seat ring 23. Figure 2 In an embodiment with a fixed rod, preferably, the arc angle of the limiting groove is between 20° and 120°. For example, if the arc angle of the limiting groove is 30°, 60° or 90°, then if the width of the fixed rod is ignored, the rotation angle range of the rotating seat ring 23 is 30°, 60° or 90°.

[0047] At least one metal detector 24 is embedded between the contact surfaces of the base 22 and the rotating ring 23. In the above embodiment, the metal detector 24 is fixed between the contact surfaces of the base 22 and the rotating ring 23 by a fixing member 241, and is configured to detect the position of at least one metal sensing element 231. When multiple metal sensing elements 231 are provided on the outer periphery of the rotating ring 23 corresponding to the arc center angle of the limiting groove, the multiple metal sensing elements 231 can be evenly distributed. In this utility model, one metal detector 24 corresponds to one metal sensing element 231. Based on electromagnetic induction, when a metal sensing element 231 approaches the metal detector 24 it is paired with, the magnetic field is disturbed, and the output voltage of the metal detector 24 is different. When the metal sensing element 231 rotates to be directly below the metal detector 24, the output voltage reaches a preset threshold, which is determined as a "positioning" signal of the metal sensing element 231. Based on the position of the metal sensing element 231 detected by the metal detector 24, the rotation angle of the rotating ring 23 can be determined.

[0048] The gripper unit is connected to the driven rotary seat 25 via the connecting plate 26. Specifically, the gripper unit includes a gripper cylinder 271 and two gripping blocks 273 respectively disposed at the two gripping ends of the gripper cylinder 271. The two gripping blocks 273 can be connected to the two gripping ends of the gripper cylinder 271 via two connecting blocks 272 respectively. The gripper cylinder 271 controls the opening and closing of the two gripping ends, that is, controls the clamping and releasing of the two gripping blocks 273.

[0049] Furthermore, to increase the contact area between the clamping surface of the clamping block and the soft sleeve fitted on the sleeve, thereby increasing the friction and maintaining clamping stability, a friction rubber block 274 can be provided on the clamping block 273. The clamping surface of the friction rubber block 274 can be an arc shape adapted to the sleeve, which can reduce the requirement for the degree of adaptation between the clamping surface and the sleeve. The gripper unit may also include a gripper motor (not shown in the figure), which is connected to and controls the movement of the gripper cylinder 271. This movement can be horizontal or upward. The rotating seat ring 23 has a T-shaped structure. The outer periphery of the bottom of the T-shaped rotating seat ring 23 rotates and engages with the inner wall of the first through hole 211. In some embodiments, the bottom of the rotating seat ring 23 can use a bearing or a low-friction coating (such as a PTFE coating) to improve the smoothness and durability of the rotation of the rotating seat ring 23.

[0050] The angle adjustment mechanism may also include a pin 234. The rotating seat ring 23 is provided with at least one positioning through hole. The pin 234 is fixedly connected to the base 22 through the at least one positioning through hole, so that when the rotating seat ring 23 rotates and drives the driven rotating seat 25 and its gripper unit to the target angle, that is, when the gripper unit drives the cloth wrapped on the sleeve to rotate to the target angle, the pin 234 is inserted into the positioning through hole to fix it, thus ensuring precise control of the rotation angle of the rotating seat ring.

[0051] The side curtain airbag installation device also includes a linear motor (not shown in the figure), with the support column 21 connected to the movable end of the linear motor. Furthermore, the side curtain airbag installation device also includes a sleeve mechanism, which includes at least one sleeve. Figure 3 In this embodiment, the sleeve mechanism 3 includes two sleeves 31 / 32. A rotating component connecting the two sleeves allows either sleeve 31 or 32 to be positioned for the application of the covering fabric. The extension direction of the sleeves 31 / 32 is parallel to the movement direction of the movable end of the linear motor. The movable end of the linear motor drives the support column 21 and its clamping block 273 to reciprocate between the two ends of a sleeve 31, thus applying the covering fabric to the sleeve 31. The number of reciprocating motions of the linear motor varies depending on the length of the covering fabric. After one piece of covering fabric is assembled on the sleeve 31, the sleeve 32 is rotated to the position where the covering fabric is to be applied, and this process is repeated. Multiple sleeves allow for continuous assembly of the soft sleeve, and the number of sleeves can be determined based on the timing between the sleeve assembly process and the next process.

[0052] Figure 3 and Figure 4 The figures show a perspective view and a side view of a side curtain airbag installation device according to one embodiment. The device includes a guide assembly and an airbag supply assembly. The guide assembly includes a guide tube 81 and a second clamping mechanism 82, which is configured to clamp the side curtain airbag sleeved on the guide tube 81. The airbag supply assembly unrolls the side curtain airbag and delivers one end of it to the guide tube 81. The side curtain airbag is then clamped onto the guide tube 81, and the airbag on the guide tube 81 is attached to one end of the sleeve 31. The clamping block 273 of the first clamping mechanism holds the airbag. The rotating seat ring 23 is rotated, and the rotation angle of the rotating seat ring 23 (side curtain airbag) is determined by the metal detector 24 and the metal sensor 231. When the target angle is reached, the pin 234 is inserted into the positioning through hole to fix the position.

[0053] In summary, the side curtain air curtain installation device of this utility model meets the adjustment needs between multiple angles during the installation of the air curtain, avoids replacing the entire device, facilitates employee operation, further optimizes some production line space, reduces the number of tooling, and saves the cost of adding new tooling.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0055] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
