Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0012] like figure 1 , 2 The control device for the three-layer offset of the blasting weakening line in the airbag area of the automobile dashboard shown in the figure includes a laser emitter 2, a mold 3 and a camera device. The laser rays emitted by the laser emitter 2 fall on the foaming mold to form light spots 1, and the position of the light spot 1 forms the position of the weakening line. According to the light spot, the foamed skin is placed in the lower mold of the mold 3, and then the traces of the weakened line on the foamed skin are taken by the camera device, and if the weakened line of the foamed skin is If the position of the reference point 4 on the surface coincides with the position of the light point 1, the foaming will be carried out. If the position of the reference point 4 of the foamed skin does not coincide...

The invention discloses a control device for three-layer deviation of a blasting weakening line in a safety airbag area of an automobile instrument board. The control device comprises a laser emitter,a die and a photographing device, wherein laser rays emitted by the laser emitter fall onto the foaming die to form a light spot, the position of the light spot forms the position of the weakening line, a foaming skin is laid into a lower die of the die according to the light spot, and then the photographing device acquires a weakening line trace on the foaming skin for photographing. A referencepoint on the weakening line is superposed with the light point when the foaming skin is laid under the guidance of the laser ray light point, so that the consistency of the skin laying position is ensured, the position of the weakening line when the foaming skin is laid is ensured to be within a tolerance range, and therefore the problem of the position deviation of the skin weakening line in themachining process of the soft instrument board is solved.
Description
technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a control device for three-layer offset of a blasting weakening line in an airbag area of an automobile instrument panel. Background technique [0002] During the production and processing of automotive soft dashboards, the stable control of the position of the blasting weakening line of the airbag on the passenger side is a difficult point in the industry. Because the skin of the softened instrument panel is mostly soft artificial leather with large size and good toughness, it is difficult to ensure the consistency of its laying position every time when the instrument panel is processed. Even with a skilled operator, the position deviation of laying the skin is still far beyond the set ±1.5mm. When the deviation of the weakening line exceeds 3mm in one direction, the airbag burst fragments may fly out, posing a threat to the personal safety of the...
