A device for detecting the residual thickness of weakened automotive dashboards

Abstract

This utility model discloses a device for detecting the residual thickness of weakened automotive dashboards, relating to the field of dashboard detection technology. The utility model includes a housing with a chamber inside, in which a monitoring component and a calibration platform are disposed. In this utility model, the dashboard body is placed on a first, second, and third placement platform. A first and second limiting plate positions the dashboard body on both sides, and a positioning groove is inserted into a positioning block, thus limiting the position of the dashboard body and improving monitoring stability. Subsequently, a negative pressure pump is activated, generating negative pressure in the connecting pipe. This causes the connecting pipe to draw air into the fixed-point detection area, which in turn attracts the dashboard body at the top, ensuring that the monitoring area of ​​the dashboard body is tightly attached to the fixed-point detection area, preventing gaps between the fixed-point detection area and the dashboard body from affecting the monitoring data.

Description

Technical Field

[0001] This utility model belongs to the field of instrument panel testing technology, and in particular relates to a device for detecting the residual thickness of weakened automotive instrument panels. Background Technology

[0002] As a key component of a vehicle's interior, the dashboard plays a crucial role in safety. The thickness of the remaining material in the airbag deployment area directly affects the safety and reliability of the airbag deployment. The dashboard weakening residual thickness detection device is a specialized instrument that precisely measures this critical indicator. By strictly controlling the machining precision of the weakening line to meet safety standards, it avoids serious problems such as fragmentation or obstructed deployment caused by residual thickness exceeding tolerances during airbag deployment, thus comprehensively protecting the lives of vehicle occupants.

[0003] In existing technologies, operators must hold the dashboard and place it on a platform, then a robotic arm drives a laser sensor to perform the detection. The data obtained is displayed on a monitor for observation. However, in the actual production process of automotive dashboards, the overall flatness of each dashboard varies to some extent. When the dashboard is placed on the platform, gaps of varying sizes inevitably appear between them, making it difficult to achieve a tight fit. This loose fit directly leads to significant errors in the detection data, failing to accurately reflect the true residual thickness of the dashboard's airbag deployment area, thus adversely affecting the assessment of the vehicle's safety performance. To date, we have provided a more reliable device for detecting the weakened residual thickness of automotive dashboards to effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the residual thickness of weakened automotive dashboards. This device solves the problem that existing dashboards have varying degrees of flatness during production, resulting in gaps of different sizes between the dashboard and the placement platform when the dashboard is placed on it, preventing it from fitting snugly against the platform and thus causing significant errors in the detection data.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a device for detecting the residual thickness of weakened parts in an automotive dashboard. The device comprises a chamber inside a housing, in which a monitoring component and a calibration platform are disposed. A placement structure is located in front of the monitoring component, comprising a first support frame, several brackets, a placement component, and a limiting component. The first support frame is fixed inside the housing, and the brackets are fixedly disposed on top of the first support frame. A switch body is also provided inside the housing, located in front of the first support frame.

[0007] The placement assembly includes a first placement platform, a second placement platform, and a third placement platform disposed above the support. The third placement platform has a fixed-point detection area at the top center and a vacuum adsorption fixing area on the outer periphery of the fixed-point detection area.

[0008] The present invention is further configured such that the first placement platform is fixedly connected to the bracket, and a first limiting plate is fixedly connected to one corner of the top of the first placement platform.

[0009] The present invention is further configured such that the second placement platform is fixedly connected to the bracket, and a positioning block is fixedly connected to the top of the second placement platform on the side away from the switch body.

[0010] The present invention is further configured such that a second limiting plate is fixedly connected to one corner of the top of the third placement platform away from the positioning block.

[0011] The present invention is further configured such that a connecting pipe is fixedly connected to one side of the bottom end of the vacuum adsorption fixing area, the connecting pipe is fixedly connected through the third placement platform, and a negative pressure pump is fixedly connected to the end of the connecting pipe away from the vacuum adsorption fixing area, and the negative pressure pump is fixedly installed on the side of the box body located on the first support frame.

[0012] The present invention is further configured such that the limiting component includes a connecting plate, the connecting plate is disposed at the bottom end of the third placement platform, and pressure rods are fixedly connected to both sides of the top end of the connecting plate.

[0013] The present invention is further configured such that a cylinder is fixedly connected to the middle of the bottom end of the connecting plate, the cylinder is fixed inside the housing located in the first support frame, and the output end of the cylinder slides through the first support frame.

[0014] The present invention is further configured such that the monitoring component includes a robotic arm body, the robotic arm body is fixed to one side inside the box, a fixing plate is fixedly connected to one end of the robotic arm body, and two laser sensors are arranged on both sides of the bottom end of the fixing plate.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the instrument panel body is placed on a first placement platform, a second placement platform, and a third placement platform. A first limiting plate and a second limiting plate position the two sides of the instrument panel body, and a positioning groove is inserted into a positioning block to limit the position of the instrument panel body, thereby improving the stability of monitoring. Then, a negative pressure pump is started. The negative pressure pump works to generate negative pressure in the connecting pipe, causing the connecting pipe to draw air into the fixed-point detection area. The fixed-point detection area adsorbs the top of the instrument panel body, so that the monitoring area of ​​the instrument panel body is in close contact with the fixed-point detection area, avoiding gaps between the fixed-point detection area and the instrument panel body that could affect the monitoring data.

[0017] If the instrument panel body is relatively rigid and the suction force of the negative pressure pump cannot make the instrument panel body fit with the fixed detection area, the starting cylinder drives the connecting plate to move down, the connecting plate drives the pressure rod to move down, and the pressure rod presses on both sides of the instrument panel body located in the vacuum adsorption fixing area, so that the instrument panel body is subjected to force and fits tightly with the fixed detection area and the vacuum adsorption fixing area, thus achieving fit.

[0027] Please see Figure 1 and Figure 2 This utility model is a device for detecting the residual thickness of weakened automotive dashboards, including a housing 1; a chamber is formed inside the housing 1, and a monitoring component and a calibration platform 4 located next to the monitoring component are arranged in the chamber; a placement structure is provided in front of the monitoring component, the placement structure includes a first support frame 31, several brackets 32, a placement component and a limiting component; the first support frame 31 is fixed inside the housing 1, and the brackets 32 are fixedly arranged on the top of the first support frame 31; a switch body 35 is also provided in the housing 1, the switch body 35 is located in front of the first support frame 31, and the monitoring component includes a robotic arm body 21, the robotic arm body 21 is fixed to one side inside the housing 1, a fixing plate 22 is fixedly connected to one end of the robotic arm body 21, and two laser sensors 23 are arranged on both sides of the bottom end of the fixing plate 22.

[0028] like Figures 1 to 4As shown, the placement assembly includes a first placement platform 33, which is fixedly connected to the bracket 32. A first limiting plate 3301 is fixedly connected to one corner of the top of the first placement platform 33. The placement assembly also includes a second placement platform 331, which is fixedly connected to the bracket 32. A positioning block 3311 is fixedly connected to the side of the top of the second placement platform 331 away from the switch body 35. The placement assembly also includes a third placement platform 332, which has a second limiting plate 3323 fixedly connected to one corner of the top of the third placement platform 332 away from the positioning block 3311. A fixed-point detection area 3322 is fixedly provided in the middle of the top of the third placement platform 332. A vacuum adsorption fixing area 3321 is fixedly provided on the outside of the fixed-point detection area 3322 on the third placement platform 332. A connecting plate is fixedly connected to one side of the bottom of the vacuum adsorption fixing area 3321. The connecting pipe 3324 is fixedly inserted through the third placement platform 332. The end of the connecting pipe 3324 away from the vacuum adsorption fixing area 3321 is fixedly connected to the negative pressure pump 3325. The negative pressure pump 3325 is fixedly installed on one side of the housing 1 located on the first support frame 31. The instrument panel assembly includes an instrument panel body 34. The instrument panel body 34 is placed on the top of the first placement platform 33, the second placement platform 331 and the third placement platform 332. The instrument panel body 34 abuts against the pressure rod 361. A positioning groove 342 is opened on one side of the middle part of the instrument panel body 34. The positioning groove 342 is engaged with the positioning block 3311. The two ends of the instrument panel body 34 abut against the first limiting plate 3301 and the second limiting plate 3323 respectively. An instrument panel detection area 341 is provided in the middle part of the side of the instrument panel body 34 near the second limiting plate 3323.

[0029] In this embodiment, the operator takes the instrument panel body 34 and places it on the first placement platform 33, the second placement platform 331, and the third placement platform 332. Both ends of the instrument panel body 34 are aligned with the first limiting plate 3301 and the second limiting plate 3323. The first limiting plate 3301 and the second limiting plate 3323 position the two sides of the instrument panel body 34, and the positioning groove 342 is inserted into the positioning block 3311, thus limiting the position of the instrument panel body 34. This completes the placement of the instrument panel body 34, improving the stability of the monitoring. Then, the negative pressure pump 3325 is started. The negative pressure pump 3325 generates negative pressure in the connecting pipe 3324, causing the connecting pipe 3324 to draw air into the fixed-point detection area 3322 for fixed-point detection. The instrument panel body 34 at the top of the instrument panel body 34 is adsorbed by the area 3322, so that the monitoring area of ​​the instrument panel body 34 is in close contact with the fixed detection area 3322, avoiding gaps between the fixed detection area 3322 and the instrument panel body 34 that would affect the monitoring data. During monitoring, the fixed plate 22 is moved by the robotic arm body 21, and the fixed plate 22 moves the laser sensor 23. The laser sensor 23 detects the instrument panel detection area 341. By setting two laser sensors 23, the two laser sensors 23 detect separately, and the two sets of data are compared and verified to improve the detection accuracy. By setting a calibration table 4, a standard sample of known thickness can be provided, so that the laser sensor 23 can compare the actual measured value with the standard value to ensure the accuracy of residual thickness detection.

[0030] like Figure 2 and Figure 5 As shown, the limiting component includes a connecting plate 36, which is disposed at the bottom of the third placement platform 332. Pressure rods 361 are fixedly connected to both sides of the top of the connecting plate 36, and a cylinder 362 is fixedly connected to the middle of the bottom of the connecting plate 36. The cylinder 362 is fixed inside the housing 1 located in the first support frame 31, and the output end of the cylinder 362 slides through the first support frame 31.

[0031] In this embodiment, if the instrument panel body 34 is relatively rigid and the suction force of the negative pressure pump 3325 is insufficient to make the instrument panel body 34 fit with the fixed-point detection area 3322, the starting cylinder 362 drives the connecting plate 36 to move down, the connecting plate 36 drives the pressure rod 361 to move down, and the pressure rod 361 presses the instrument panel body 34 on both sides of the vacuum adsorption fixing area 3321, so that the instrument panel body 34 is subjected to force and fits tightly with the fixed-point detection area 3322 and the vacuum adsorption fixing area 3321, thus achieving fit.

[0032] The operation process of this embodiment is as follows: First, during use, the instrument panel body 34 is placed on the first placement platform 33, the second placement platform 331, and the third placement platform 332. The first limiting plate 3301 and the second limiting plate 3323 position the two sides of the instrument panel body 34, and the positioning groove 342 is inserted into the positioning block 3311, so that the position of the instrument panel body 34 is limited, improving the stability of the detection. Then, the negative pressure pump 3325 is started. The negative pressure pump 3325 generates negative pressure in the connecting pipe 3324, causing the connecting pipe 3324 to draw air into the fixed-point detection area 3322. The fixed-point detection area 3322 adsorbs the top of the instrument panel body 34, so that the monitoring area of ​​the instrument panel body 34 is in close contact with the fixed-point detection area 3322, avoiding gaps between the fixed-point detection area 3322 and the instrument panel body 34 that would affect the monitoring data. If the instrument panel body 34 is too hard overall, and the suction force of the negative pressure pump 3325 is insufficient to make the instrument panel body... When the instrument panel body 34 is in contact with the fixed detection area 3322, the starting cylinder 362 drives the connecting plate 36 to move down, and the connecting plate 36 drives the pressure rod 361 to move down. The pressure rod 361 presses against both sides of the instrument panel body 34 located in the vacuum adsorption fixing area 3321, so that the instrument panel body 34 is subjected to force and is in close contact with the fixed detection area 3322 and the vacuum adsorption fixing area 3321, thus achieving contact. During monitoring, the mechanical arm body 21 drives the fixing plate 22 to move, and the fixing plate 22 drives the laser sensor 23 to move. The laser sensor 23 detects at the instrument panel detection area 341. By setting two laser sensors 23 and detecting separately, the two sets of data are cross-validated to control the measurement error within the specified range and improve the detection accuracy. By setting the calibration table 4, a standard sample of known thickness can be provided, so that the laser sensor 23 can compare the actual measured value with the standard value, correct the system error, and ensure the accuracy of residual thickness detection.
