Description

Technical Field

[0001] This utility model relates to the field of dashboard skin weakening technology, and specifically to a dashboard skin weakening platform. Background Technology

[0002] The weakening treatment of a car dashboard specifically involves creating a predetermined tear path on it. When the airbag inflates, it will rupture along the predetermined path to ensure that the airbag can deploy correctly and quickly in the event of a collision. Existing weakening treatment methods usually use lasers, that is, using a high-precision laser beam to cut weakening lines of predetermined shape and depth on the dashboard surface to ensure that the position and depth of the weakening lines are accurate.

[0003] For example, Chinese patent application number CN201921651266.7 discloses a dashboard skin weakening device, including a jig for positioning the skin to be weakened, a blade above the jig, and a measuring unit beside the blade to detect the displacement of the blade in the cutting thickness direction. This unit can detect the blade displacement online, thereby judging the blade displacement in real time and correcting the blade deviation in a timely manner, thus ensuring the uniformity of the residual material thickness. However, its measuring unit can only detect the residual material thickness based on the blade displacement. After weakening, the weakened area of ​​the dashboard skin often shows path deviation. Judging the passability solely based on the operator's experience cannot accurately assess whether the obtained weakening line is reasonable. Applying dashboard skin that does not conform to the expected tear path will affect the deployment effect of the airbag. Utility Model Content

[0004] The purpose of this invention is to provide a dashboard skin weakening platform to solve the technical problems of existing measuring units being able to detect residual material thickness only based on blade displacement, and the path deviation often occurring in the weakened area of ​​the dashboard skin after weakening treatment. The degree of qualification is judged solely based on the operator's experience, making it impossible to accurately assess whether the obtained weakening line is reasonable. Applying dashboard skin that does not conform to the expected tear path will affect the deployment effect of the airbag.

[0005] A dashboard skin weakening platform includes a frame and a base plate disposed on the frame, and further includes a perforated membrane for positioning the weakened skin. The perforated membrane is detachably disposed on the base plate. The base plate is provided with a negative pressure air source for adsorbing the perforated membrane. Both sides of the base plate are provided with liftable clamping plates. The weakening platform also includes two transparent plates disposed opposite each other. The frame is provided with a drive mechanism in the middle for driving the transparent plates to flip.

[0006] Preferably, the driving mechanism includes a cylinder and a tilting plate. The cylinder is mounted on the frame via a base. The output end of the cylinder is provided with a connecting plate. There are two tilting plates. The transparent plate is mounted on the tilting plates. The two tilting plates are respectively hinged to both sides of the base. Push-pull blocks are installed at both ends of the connecting plate. The push-pull blocks are slidably disposed on both sides of the tilting plate.

[0007] Preferably, the upper end of the transparent plate is provided with a threaded rod, which is adjustablely mounted on the flip plate by means of a locking nut.

[0008] Preferably, the upper end of the push-pull block has a U-shaped structure and sliding columns are provided on both sides. The flip plate has sliding grooves on both sides, and the sliding columns are slidably disposed in the sliding grooves.

[0009] Preferably, when the output end of cylinder one is fully extended, the transparent plate is placed to the side of the perforated membrane.

[0010] Preferably, the lower end of the transparent plate has a detachable patch, the patch being made of transparent material and having a weakening line trajectory, the weakening line trajectory corresponding to the weakening line of the weakened surface.

[0011] Preferably, the substrate is provided with cylinders 2 in both the horizontal and vertical directions, and the clamping plates are respectively disposed on the output ends of each cylinder 2.

[0012] The advantages of this utility model are as follows: the perforated membrane and the instrument panel skin are positioned by a negative pressure air source, and the edge of the instrument panel skin is further clamped and fixed by a clamping plate. After the weakening operation is completed, the transparent plate is flipped downward by a drive mechanism so that the patch at the lower end of the transparent plate can abut against the weakening line on the instrument panel skin. The weakening line and the trajectory on the patch can be compared to achieve intuitive observation and comparison to determine whether the tear path meets the expectations, thus ensuring the product quality of the instrument panel skin after weakening.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1 to 5 As shown, an instrument panel skin weakening platform includes a frame 1 and a base plate 2 disposed on the frame 1. It also includes a perforated membrane 3 for positioning the weakened skin. The perforated membrane 3 is detachably disposed on the base plate 2. The base plate 2 is provided with a negative pressure air source 4 for adsorbing the perforated membrane 3. Both sides of the base plate 2 are provided with liftable clamping plates 5. The weakening platform also includes two transparent plates 6 disposed opposite to each other. The frame 1 is provided with a drive mechanism in the middle for driving the transparent plates 6 to flip.

[0021] In this embodiment, the driving mechanism includes a cylinder 7 and a flip plate 8. The cylinder 7 is mounted on the frame 1 via a base 9. The output end of the cylinder 7 is provided with a connecting plate 10. There are two flip plates 8. A transparent plate 6 is mounted on the flip plate 8. The two flip plates 8 are respectively hinged to both sides of the base 9. Push-pull blocks 11 are installed at both ends of the connecting plate 10. The push-pull blocks 11 are slidably disposed on both sides of the flip plate 8.

[0022] In this embodiment, the upper end of the transparent plate 6 is provided with a threaded rod 12, which is adjustablely mounted on the flip plate 8 by means of a locking nut.

[0023] In this embodiment, the upper end of the push-pull block 11 has a U-shaped structure, and sliding columns 13 are provided on both sides. Sliding grooves 14 are provided on both sides of the flip plate 8, and the sliding columns 13 are slidably disposed in the sliding grooves 14.

[0024] In this embodiment, when the output end of cylinder 7 is fully extended, the transparent plate 6 is placed to the side of the perforated membrane 3.

[0025] In this embodiment, the lower end of the transparent plate 6 is detachably fitted with a patch 15. The patch 15 is made of transparent material and has a weakening line trajectory, which corresponds to the weakening line of the weakened skin.

[0026] In this embodiment, cylinders 16 are provided in both the horizontal and vertical directions of the substrate 2, and clamping plates 5 are respectively provided on the output end of each cylinder 16.

[0027] Working process and principle: In this embodiment, the perforated membrane 3 is first placed on each negative pressure air source 4 to complete the positioning. Then, the instrument panel skin to be weakened is laid on the perforated membrane 3. Under negative pressure, the instrument panel skin can be firmly adsorbed on the perforated membrane 3. Then, the cylinders 16 arranged in the horizontal and vertical directions on the base plate 2 drive the clamping plate 5 to descend and clamp the edge of the instrument panel skin, further clamping and fixing the edge of the instrument panel skin, so as to achieve precise positioning of the instrument panel skin.

[0028] Subsequently, a high-precision laser beam cuts a weakening line of predetermined shape and depth on the dashboard surface. After the weakening operation is completed, the laser beam is withdrawn, and the cylinder 7 on the base 9 is activated to reset its output end, thereby pulling the connecting plate 10 downward. Under the action of the push-pull block 11, the sliding column 13 on the push-pull block 11 can slide in the sliding groove 14, thereby enabling the flip plate 8 to drive the transparent plate 6 to flip downward synchronously, so that the patch 15 at the lower end of the transparent plate 6 can abut against the weakening line on the dashboard surface. The weakening line and the trajectory on the patch 15 can be compared to achieve intuitive observation and comparison to determine whether the tear path meets the expectations.

[0029] Based on the above, this utility model uses a negative pressure air source 4 to position the perforated membrane 3 and the dashboard skin, and the clamping plate 5 further clamps and fixes the edge of the dashboard skin. After the weakening operation is completed, the transparent plate 6 is driven to flip downward by the drive mechanism so that the patch 15 at the lower end of the transparent plate 6 can abut against the weakening line on the dashboard skin. The weakening line and the trajectory on the patch 15 can be compared to achieve intuitive observation and comparison to determine whether the tear path meets the expectations, thus ensuring the product quality of the dashboard skin after weakening.

[0030] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
