Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of instrument panel covering, in particular to a precise alignment device for a layered weakened instrument panel. Background Art
[0002] As consumers' demand for car interior comfort continues to improve, more and more luxury car dashboards are covered with leather. The more mature practice in the industry is: 3D mesh (3D mesh, also known as 3D material or 3D spacer fabric. It is a new pure fabric material with excellent breathability, elasticity and support) and leather are weakened by cold light source laser, while the skeleton is weakened by carbon dioxide laser, and then the skeleton, epidermis and mesh are aligned.
[0003] There are two main ways to cover the skeleton and mesh after layering and weakening:
[0004] a. Fold along the weakened line of the mesh airbag area, and then visually align the weakened line of the skeleton to wrap. This method is inefficient, and folding the mesh is likely to cause uneven mesh surface defects;
[0005] b. Install a laser irradiation module above the tooling, project the weakening line onto the surface of the frame A, and then use the mesh weakening line to align with the laser module projection line to cover it. This method improves efficiency and quality, but due to the inevitable deformation of the injection molded frame itself, its own weakening line often deviates from the theoretical position, resulting in an error with the mesh weakening line position indicated by the laser module; at the same time, the laser weakening print of the mesh is not clear, resulting in inconvenience in operation. Utility Model Content
[0006] In view of the above problems, the utility model provides a precise alignment device for a layered weakened instrument panel, including a skeleton airbag covering tool, a laser irradiation module and a transmission laser module. The skeleton is placed on the skeleton airbag covering tool, a laser irradiation module is arranged on one side of the skeleton airbag area, and a transmission laser module is arranged on the other side of the skeleton airbag area. The positions of the skeleton airbag covering tool and the transmission laser module are fixed, and the positions of the laser irradiation module and the skeleton airbag covering tool can be moved arbitrarily. The laser emitted by the transmission laser module can pass through the weakening line, and the laser emitted by the laser irradiation module is "H" shaped; the utility model can realize automatic tracking of the skeleton weakening line, eliminate the influence of skeleton deformation on the position of the weakening line; the positioning is accurate, and can ensure that the deviation between the mesh weakening line and the skeleton weakening line after covering is controlled within the range of ±1.0mm; the production efficiency is high. The utility model is suitable for the layered weakened covering instrument panel of the airbag area.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connection", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral connection; the connection can be a mechanical connection or an electrical connection; the connection can be a direct connection or an indirect connection through an intermediate medium, and can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] Figure 2 Described is the method of laser weakening the epidermis, mesh and skeleton to form weakened lines before the lines are wrapped.
[0024] A device for precisely aligning a layered weakened instrument panel comprises: an instrument panel frame 1, a laser irradiation module 2 and a transmission laser module 3, and a frame airbag covering tool 4. The instrument panel frame 1 is placed on the frame airbag covering tool 4, a weakening line 104 is provided on the instrument panel frame 1, the laser irradiation module 2 is provided on one side of the instrument panel frame 1, and the transmission laser module 3 is provided on the other side of the instrument panel frame 1.
[0025] The positions of the skeleton airbag covering tooling 4 and the transmission laser module 3 are fixed.
[0026] The positions of the laser irradiation module 2 and the skeleton airbag covering tooling 4 can be moved arbitrarily.
[0027] The laser light emitted by the transmission laser module 3 can pass through the weakened line 104 .
[0028] The laser emitted by the laser irradiation module 2 is "H" shaped.
[0029] The distance between the transmission laser module 3 and the skeleton airbag covering tooling 1 is 10-20 mm.
[0030] The instrument panel skeleton 1 comprises: a skin 101 , a 3D mesh 102 , a skeleton 103 and a weakened line 104 obtained after processing.
[0031] The weakened line 104 on the epidermis 101 is weakened by cold light source laser.
[0032] The weakened line 104 on the 3D mesh 102 is weakened by a cold light source laser.
[0033] The weakening line 104 on the skeleton 103 is weakened by CO2 laser.
[0034] The three weakening lines 104 overlap in position.
[0035] The utility model is to install a laser irradiation module above the coating tooling and install a transmission laser module below the frame airbag area. When working, the transmission laser module is turned on, and the light beam passes through the frame weakening hole to leave a bright line on the frame A surface, and then the laser irradiation module is turned on to form a weakening line on the frame A surface. By adjusting the position of the laser irradiation module, the bright line from the bottom and the projection line from the top are overlapped, and then the mesh coating is started. When the bright line from the bottom appears on the mesh A surface again and overlaps with the projection line from the top, it proves that the weakening lines of the frame and the mesh are aligned, and can be bonded and fixed.
