Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, and more specifically to a multi-car model auxiliary material pasting device. Background Art

[0002] With the development of lightweight automobiles, the design thickness of automobile outer panels is relatively thin, and the strength of steel plates is insufficient. Generally, the stiffness of weak positions is improved by pasting films. The application scope includes automobile doors, engine hoods, trunk lids, fenders, roofs and other parts. The shape design of four-door outer panels is generally simple, and there are no holes, edges, reinforcement ribs and other features on the inside. In addition, since most of the current film pasting work is manual pasting, workers cannot find a suitable reference position when pasting the film, and cannot ensure that the film pasting position is consistent with the design position. The deviation of the film position will cause the outer panel to fail to achieve the designed stiffness after baking, and will also increase the vibration frequency, causing the vehicle to produce low noise during driving.

[0003] In the prior art, manual pasting can choose to use auxiliary jigs for auxiliary positioning to ensure the consistency of the material pasting position. This type of auxiliary jigs generally use positioning holes for positioning, but there are no holes on the inner side of the four-door outer panels, so they can only be positioned using the contour edges. The contour edges of the four-door outer panels have a large span, so a longer jig needs to be designed, which makes the jig as a whole long and heavy, inconvenient to operate, and the jig needs to be pressed on the four-door outer panels when used, which can easily cause sheet metal defects. Moreover, this type of jig can only be used to position a single film corresponding to a single type of vehicle model. When gluing different films of a single type of vehicle model or different films of multiple types of vehicles, different auxiliary jigs need to be designed additionally, which has great limitations in use and high cost of use. In addition, when the working environment is not well lit, workers are also prone to pasting offsets. Utility Model Content

The second fastening assembly 205 is used to fix the first connecting assembly 204 on the connecting rod 202. The laser emitter 3 is connected to the first connecting assembly 204. The first connection assembly 204 includes a first connection member 2041 slidably connected to the connection rod 202, a second connection member 2042 rotatably connected to the first connection member 2041, and a third fastening assembly 2043 connected to the first connection member 2041. The third fastening assembly 2043 is used to lock the second connection member 2042 on the first connection member 2041, and the laser emitter 3 is connected to the second connection member 2042. The first connection assembly 204 also includes a mounting member 2044 rotatably connected to the second connection member 2042, and a fourth fastening assembly 2045 connected to the second connection member 2042. The fourth fastening assembly 2045 is used to lock the mounting member 2044 on the second connection member 2042. The laser emitter 3 is connected to the mounting member 2044, and the rotation axis of the mounting member 2044 is perpendicular to the rotation axis of the second connection member 2042. The first connecting member 2041 is provided with a plurality of first arc-shaped holes 4 with the centers of the circles coinciding with each other, and the second fastening assembly 205 fixes the first connecting member 2041 to the connecting rod 202 through the first arc-shaped holes 4. The mounting member 2044 has the same structure as the first connecting member 2041.

[0046] After the first fastening assembly 203 is loosened, the connecting rod 202 can slide vertically relative to the vertical rod 201, thereby adjusting the height of the connecting rod 202 and the laser emitter 3 to adapt to different materials. The specific connection structure of the connecting rod 202 and the vertical rod 201 is not limited, and it is only necessary to satisfy that the connecting rod 202 can move vertically relative to the vertical rod 201, and the connecting rod 202 can be fixed after the moving position. The first connecting assembly 204 slides horizontally relative to the connecting rod 202 as a whole, and is fastened by the second fastening assembly 205. The laser emitter 3 is connected to the first connecting assembly 204 and moves with the first connecting assembly 204 to achieve lateral adjustment of the laser emitter 3, thereby achieving the function of the adjustment assembly 2 to adjust the position of the laser emitter 3 in multiple directions, so that the laser emitter 3 can adapt to more types of materials. In the first connecting assembly 204, the first connecting member 2041 is connected to the connecting rod 202 by transverse sliding, the second fastening assembly 205 fixes the first connecting member 2041 on the connecting rod 202, and the second connecting member 2042 rotates relative to the first connecting member 2041, so that the laser emitter 3 can rotate with the second connecting member 2042, further increasing the adjustable range of the laser emitter 3. The laser emitter 3 is mounted on the mounting member 2044, and the mounting member 2044 rotates relative to the second connecting member 2042, and the rotation axis of the mounting member 2044 is perpendicular to the rotation axis of the second connecting member 2042, so as to further increase the adjustable range of the laser emitter 3.

The first connecting member 2041 and the connecting rod 202 are locked together by tightening the bolts or locking the locks. When the bolts or locks are loosened, the first connecting member 2041 can be rotated with the first arc hole 4 as a guide, so that the first connecting member 2041 can slide relative to the connecting rod 202, and can also rotate relative to the connecting rod 202, which can further increase the adjustable range of the laser emitter 3. The mounting member 2044 has the same structure as the first connecting member 2041. The mounting member 2044 is also provided with a first arc hole 4. Specifically, the laser emitter 3 is mounted on the mounting member 2044 by a fastener, and the fastener passes through the first arc hole 4 on the mounting member 2044 and is connected to the laser emitter 3.

[0047] Furthermore, the vertical rod 201 and the connecting rod 202 are both made of aluminum profiles, which saves costs.

[0048] Furthermore, the second connecting member 2042 and the first connecting member 2041 are rotatably connected by bolts and nuts, and are also locked by bolts and nuts. Figure 3 As shown, the second connecting member 2042 and the first connecting member 2041 are connected with two groups of bolts and nuts as the rotation axis, and the second connecting member 2042 rotates with the two groups of bolts and nuts as the rotation center. It is more convenient to disassemble by setting the bolts and nuts as the rotation axis; at the same time, two groups of bolts and nuts are connected with each other as the locking members, and at the same time, a second arc hole 10 is provided on the first connecting member 2041, and the second arc hole 10 is used to avoid the bolts and limit the rotation angle of the bolts. When the second connecting member 2042 rotates, the bolts and nuts can be tightened and locked at any position of the second arc hole 10, and the second connecting member 2042 is locked on the first connecting member 2041. Further, the connection structure between the mounting member 2044 and the second connecting member 2042 is consistent with the connection structure between the second connecting member 2042 and the first connecting member 2041.

Furthermore, the fill light 5 is a soft light. The second connecting component 6 is installed on the vertical rod 201, and can slide vertically relative to the vertical rod 201 to adjust the position of the fill light 5. After the adjustment, it is fixed by the fifth fastening component 7. The first connecting component 204 has the function of multi-directional adjustment. The structure of the second connecting component 6 is consistent with the first connecting component 204, so that the fill light 5 can also be adjusted in multiple directions, which is more convenient to use.

[0054] like Figure 4 As shown, further, the fill light 5 is located above the laser emitter 3.
