Detailed Implementation

[0017] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the multi-functional aftermarket windshield inspection device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0018] This embodiment provides a multi-functional aftermarket windshield testing device, including: A glass support and positioning mechanism includes at least one set of servo clamping arms 1 and at least two first servo drive shafts 2. The servo clamping arms 1 are used to clamp or release the glass along the width direction of the glass, and the first servo drive shafts 2 are used to drive the glass to perform lifting and lowering movements and left and right posture adjustments. A glass angle adjustment mechanism is located below the glass support and positioning mechanism, and includes a gantry tilt mechanism 3, which is used to adjust the glass to the loading angle. The HUD projection mechanism is located below the glass detection area and includes a HUD light box and a six-axis adjustment component 4. The six-axis adjustment component 4 is used to drive the HUD light box to move in six directions: X, Y, Z, W, U, and V, so that the projection pattern is accurately projected onto the HUD detection area of ​​the glass. A camera inspection mechanism, comprising an industrial camera and a three-axis motion module 5, wherein the three-axis motion module 5 is used to drive the industrial camera to move in the X, Y and Z directions to perform optical performance testing on the glass; The appearance inspection mechanism includes a rotatable light source configured to rotate ±18.5° around a horizontal axis for inspecting the appearance quality of glass.

[0019] This device achieves precise clamping of the glass in the width direction and electric adjustment of its left and right posture through a combination of servo clamping arms and at least two first servo drive shafts. Combined with a gantry pitch mechanism to simulate the actual loading angle, it reduces the glass positioning deviation from more than ±5mm in manual operation to ±0.1mm in servo system control, fundamentally ensuring the benchmark consistency of HUD optical inspection.

[0020] The HUD light box is driven by a six-axis adjustment component (X, Y, Z, W, U, V directions), which can achieve micron-level precise alignment for the positional differences of the HUD area on the glass of different car models, so that the projected pattern is always incident at the optimal angle, reducing the repeatability error of ghost detection by more than 60%.

[0021] The rotatable light source with a ±18.5° structural design provides standardized dynamic lighting conditions for appearance inspection, avoiding the angle fluctuations of manually held light sources and significantly improving the consistency of the detection rate of defects such as scratches and bubbles.

[0022] For details, please refer to Figure 1 The glass support and positioning mechanism includes two sets of servo clamping arms 1, which are respectively set on both sides of the glass along the width direction. Each set of servo clamping arms 1 is driven by an independent servo motor.

[0023] Each set of servo clamping arms 1 includes a clamping arm body 11 and a clamping servo motor shaft 12. The clamping arm body 11 has a clamping surface that matches the contour of the glass edge. The clamping servo motor shaft 12 drives the clamping arm body 11 to move in the horizontal direction.

[0024] Please refer to Figure 2 In this embodiment, at least two first servo drive shafts 2 are symmetrically arranged on both sides of the glass support surface, and each first servo drive shaft 2 is independently controlled to realize the left and right posture adjustment and lifting movement of the glass.

[0025] In practical applications, the servo clamping arm 1 can be opened to a general position (the position depends on the width of the glass); then the two first servo drive shafts 2 can be returned to the origin and adjusted to a suitable position (the position depends on the size of the glass); the glass can be manually loaded by placing it on the device, adjusting the servo clamping arm 1 and the first servo drive shaft 2 to reach a suitable loading position, and saving the loading parameters.

[0026] After the standard sample glass is placed on the device, the glass can be raised and lowered left and right through the two first servo drive shafts 2 to center the glass and raise it to the specified height; then the glass is clamped and fixed by the clamping servo motor shaft 12 of the servo clamping arm 1 to reduce the deviation value of the glass and save the clamping servo motor shaft parameters.

[0027] The gantry pitch mechanism in this embodiment includes a gantry frame and a pitch servo drive shaft. The drive end of the pitch servo drive shaft is connected to the glass support and positioning mechanism to drive the glass to rotate around the horizontal axis to a predetermined loading angle.

[0028] Please refer to Figure 3 After the standard sample glass is clamped, the glass is adjusted to the angle of the glass to be installed on the vehicle through the gantry pitch mechanism 3 to simulate the actual installation test conditions and save the pitch servo drive shaft parameters.

[0029] The three-axis motion module 5 in this embodiment includes an X-axis motion component 51, a Y-axis motion component 52, and a Z-axis motion component 53. An industrial camera is mounted at the end of the Z-axis motion component 53, which is mounted on the Y-axis motion component 52, and the Y-axis motion component 52 is mounted on the X-axis motion component 51.

[0030] Please refer to Figure 4 The industrial camera is moved along the X-axis by the X-axis moving component 51, then along the Y-axis by the Y-axis moving component 52, and finally along the Z-axis by the Z-axis moving component 53, until the industrial camera is moved to the approximate detection position, which is convenient for subsequent fine-tuning (the display area will display the pattern after the HUD light box is adjusted).

[0031] The six-axis adjustment assembly 4 in this embodiment includes an X-axis moving assembly 41, a Y-axis moving assembly 42, a Z-axis moving assembly 43, a W-axis rotating assembly 44, a U-axis rotating assembly 45, and a V-axis rotating assembly 46. The HUD light box is fixed to the end of the V-axis rotating assembly 46 by bolts and positioning pins. The rotation axis of the W-axis rotating assembly 44 is parallel to the X-axis, the rotation axis of the U-axis rotating assembly 45 is parallel to the Y-axis, and the rotation axis of the V-axis rotating assembly 46 is parallel to the Z-axis.

[0032] Please refer to Figure 5 The HUD lightbox is fixed to the position of the V-axis rotating component 46 by bolts and positioning pins. The X-axis moving component 41 drives the lightbox to move in the X direction, the Y-axis moving component 42 drives the lightbox to move in the Y direction, the Z-axis moving component 43 drives the lightbox to move in the Z direction, the W-axis rotating component 44 drives the lightbox to move in the W direction, the U-axis rotating component 45 drives the lightbox to move in the U direction, and the V-axis rotating component 46 drives the lightbox to move in the V direction. Through the adjustment of the above six axes, the pattern projected by the lightbox is displayed on the glass detection area, and in conjunction with the gantry tilt mechanism 3, the final display pattern ghosting effect is minimized.

[0033] Please refer to Figure 6 Once the ghosting effect is optimal, the camera takes a picture and saves it for algorithm processing. After processing, the parameters and the project are saved for easy access next time. The glass support positioning mechanism, glass angle adjustment mechanism, HUD projection mechanism, and camera detection mechanism return to the loading position.

[0034] After returning to the loading position, place the product to be tested, press start, and adjust the components to move the glass to the testing position. Please refer to [link / reference needed]. Figure 7 When the appearance quality inspection light source illuminates, the servo axis 6 of the rotatable light source will rotate ±18.5° left and right. A person observes the projection to determine whether the inspected glass meets the appearance quality standards. The device will then continue operating to perform optical performance testing. This rotatable light source can be a linear or strip light source.

[0035] The mechanisms in the above-mentioned device can be adjusted manually or operated automatically. When operating automatically, a control unit is required. This control unit is electrically connected to each mechanism and is used to control the movement of each mechanism and save the detection parameters. Specifically, the control unit can be configured to calibrate the detection parameters of a standard sample glass and save them as reference parameters. When testing the product to be tested, the reference parameters are automatically called to control the movement of each mechanism to the detection position.

[0036] In summary, this aftermarket windshield multi-functional testing device, through its innovative multi-axis linkage integrated architecture, has built a systematic advantage in testing accuracy and efficiency, precisely solving the core problems of uncontrollable quality, low efficiency, and difficulty in replacement that have long existed in the field of aftermarket windshield testing.
