Description

Technical Field

[0001] The utility model provides a detection device for the weakening line of an automotive instrument panel, which relates to the technical field of automotive instrument panel detection. Background Technique

[0002] An automotive instrument panel generally consists of a skeleton, a foaming layer, and a surface skin. The production process of a safety airbag instrument panel is not complex, and the key points in the production process lie in controlling the precision of the skin weakening and the skeleton weakening. If the residual thickness is too thick, when the airbag explodes, the instrument panel cannot be smoothly opened, the airbag cannot be smoothly ejected, and it is difficult to ensure the safety of the front-row occupants; if the residual thickness is too thin, scratches can be seen on the surface of the instrument panel, affecting the aesthetics and integrity of the instrument panel.

[0003] In the prior art, for the detection of the weakening line of the instrument panel, a dial indicator and a caliper are used by manual to measure the residual thickness and the bridge width. Due to measurement errors and manual errors, it is very difficult to accurately measure the same position of different products. On this basis, we have developed a special device for accurately positioning and measuring the weakening area of the instrument panel. For this reason, we propose a detection device for the weakening line of an automotive instrument panel. Content of the Utility Model

The detection table includes a second detection platform slidably arranged on the top of the frame and a first detection platform slidably arranged on the top of the second detection platform, and the moving directions of the second detection platform and the first detection platform are perpendicular to each other. A grating scale is fixedly connected to one side of the second detection platform, and an arrow matched with the grating scale is fixedly connected to one side of the first detection platform. A second crank is arranged on one side of the frame for controlling the movement of the second detection platform, and a first crank is arranged on the second detection platform for controlling the movement of the first detection platform. A U-shaped bracket is fixedly installed on one side of the frame. The U-shaped bracket penetrates through the frame and is fixedly connected with an upper-line laser sensor and a lower-line laser sensor at both ends respectively.

[0018] The preferred embodiments of the present utility model will be described in detail below with reference to the drawings.

[0019] Refer to Figures 1 to 4, the present utility model provides an automotive instrument panel weakening line detection device, including a frame 1. A detection table is arranged on the frame 1. The detection table includes a second detection platform 6 slidably arranged on the top of the frame 1 and a first detection platform 5 slidably arranged on the top of the second detection platform 6, and the moving directions of the second detection platform 6 and the first detection platform 5 are perpendicular to each other. A grating scale 8 is fixedly connected to one side of the second detection platform 6, and an arrow 10 matched with the grating scale 8 is fixedly connected to one side of the first detection platform 5. A second crank 9 for controlling the movement of the second detection platform 6 is arranged on one side of the frame 1, and a first crank 12 for controlling the movement of the first detection platform 5 is arranged on the second detection platform 6. Specifically, place the instrument panel to be detected on the first detection platform 5. The positions of the first detection platform 5 and the second detection platform 6 can be moved through the first crank 12 and the second crank 9. The grating scale 8 is equipped with an encoder. Through the value of the encoder, the position to be measured can be confirmed. The encoder adopts the existing technology. The encoder converts the displacement into a periodic electrical signal, and then converts this electrical signal into a counting pulse, and uses the number of pulses to represent the magnitude of the displacement.

[0020] Further, as Figure 3 shown, a U-shaped bracket 3 is fixedly installed on one side of the frame 1. The U-shaped bracket 3 penetrates through the frame 1 and is fixedly connected with an upper line laser sensor 4 and a lower line laser sensor 14 at both ends respectively. Specifically, the upper line laser sensor 4 is perpendicular to the upper part of the weakening line. By emitting a whole line of laser points and analyzing the reflection time and the attenuation degree of the light at different points, the cutting depth at different positions and the width of the weakening line bridge can be judged. At the same time, the lower line laser sensor 14 on the back scans the back of the weakening line. Since the distance between the two line lasers remains unchanged, the value obtained by subtracting the measured values of the two line lasers from the distance between the two line lasers is the residual thickness of the measured area.

[0021] Further, as Figure 4 shown, a first detection window 19 is opened on the first detection platform 5, and a second detection window 20 is opened on the second detection platform 6. The positions of the first detection window 19 and the second detection window 20 correspond to the upper line laser sensor 4. The first detection window 19 and the second detection window 20 can expose the detection area of the instrument panel, facilitating the upper line laser sensor 4 and the lower line laser sensor 14 to measure the instrument panel.

[0022] Further, second guide rails 13 are symmetrically and fixedly connected to the top of the frame 1. Second sliders 17 that cooperate with the second guide rails 13 are fixedly connected to the bottom of the second detection platform 6. First guide rails 16 are symmetrically and fixedly connected to the second detection platform 6. First sliders 15 that cooperate with the first guide rails 16 are fixedly connected to the bottom of the first detection platform 5. Specifically, the cross-sections of the first guide rails 16 and the second guide rails 13 are both I-shaped. Through the cooperation of the first guide rails 16 and the first sliders 15, and the cooperation of the second guide rails 13 and the second sliders 17, the translation of the first detection platform 5 and the second detection platform 6 can be guided and limited.

[0023] Further, a first linear movement mechanism 11 is provided between the first crank 12 and the first detection platform 5. The first linear movement mechanism 11 is installed on the second detection platform 6 through a support block 18. A second linear movement mechanism 7 is provided between the second crank 9 and the second detection platform 6. The second linear movement mechanism 7 is arranged inside the frame 1. Specifically, both the first linear movement mechanism 11 and the second linear movement mechanism 7 adopt a lead screw and slider structure. The first crank 12 and the second crank 9 are respectively coaxially and fixedly connected to the ends of the corresponding lead screws. The lead screw and the slider are relatively common movement mechanisms in the prior art, so their specific structures and working principles will not be elaborated.

[0024] Further, a display screen 2 is also provided on the frame 1. Specifically, the display screen 2 is used to display measurement data.

[0025] Working principle: Place the instrument panel to be detected on the first detection platform 5. Control the left and right movement of the second detection platform 6 through the second crank 9, control the front and back movement of the first detection platform 5 through the first crank 12. At the same time, determine the measured position by reading the data on the grating scale 8. Then, emit a whole line of laser points through the upper line laser sensor 4, analyze the reflection time and the attenuation degree of the light at different points, so as to judge the cutting depth at different positions and the width of the weakening line bridge. At the same time, the lower line laser sensor 14 on the back scans the back of the weakening line. Since the distance between the two line lasers remains unchanged, the value obtained by subtracting the measured values of the two line lasers from the distance between the two line lasers is the residual thickness of the measured area.

[0026] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, creatively design a structural manner and an embodiment similar to the technical solution, they shall fall within the protection scope of the present invention.
