Description

Technical Field

[0001] The present invention relates to the technical field of backlight debugging, and particularly relates to a HUD backlight debugging device. Background Art

[0002] The Head-Up Display (HUD) system, as a key human-machine interface, has been widely used in fields such as automobiles, aviation, and industry. Its core function is to project key information (such as vehicle speed, navigation, flight parameters, etc.) into the user's field of vision through optical projection technology, avoiding distraction of attention caused by line-of-sight switching. In this process, the backlight module, as the core component of the HUD, directly determines key performance indicators such as display brightness, uniformity, and color reproduction. Therefore, the debugging accuracy of the backlight directly affects the final imaging quality and user experience of the HUD. Existing HUD backlight debugging technologies mostly rely on separate devices. In the batch detection of production enterprises, the single detection efficiency of using separate devices is low, and corresponding improvements need to be made to the existing problems to improve the detection efficiency.

[0003] In the prior art, a Chinese patent document with the publication number CN221572963U was proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: The utility model provides a backlight debugging device, including: a workbench, a clamping device is slidably installed between the workbenches, a backlight can be installed on the clamping device, a lighting frame is fixedly installed at the center top of the workbench, a light source is movably installed at the bottom end of the lighting frame, a detector is arranged at the bottom of the lighting frame, and a controller is installed on the workbench on the right side of the lighting frame. This kind of backlight debugging device can continuously detect multiple backlights in sequence, improve the efficiency of backlight debugging detection, and the disassembly and assembly of the backlight are simple and convenient.

[0004] It can be seen from the technical solution proposed in the above patent document that the above solution still has obvious deficiencies. For example, the technical principle of the HUD is optical projection. Therefore, the backlights in the HUD are mostly made of transparent materials with high permeability, and their hardness is relatively low. If the clamping method is used to fix them, not only the backlight is easily damaged during the clamping process, but also detection dead angles will be generated in the clamped parts, making the detection results inaccurate. Therefore, the prior art urgently needs a technical solution to solve the above problems. Summary of the Invention

Detailed implementation manners

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] First, the concepts involved in the present application will be described in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of the present application easier to understand and do not represent a limitation on the protection scope of the present application; at the same time, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] Embodiment:

[0031] As Figures 1 to 7 shown, the present invention provides an HUD backlight debugging device, including a conveyor 1. A conveyor belt 11 is installed inside the conveyor 1. Along the conveying direction of the conveyor belt 11, a first observation assembly 2 for detecting the posture of the backlight on the conveyor belt 11, a feeding device 3 for preventing the backlight from being conveyed along the edge, a second observation assembly 21 for reconfirming the posture of the backlight on the conveyor belt 11, and an adjusting mechanism 6 for adjusting the position of the backlight on the conveyor belt 11 are successively installed on the top of the conveyor 1. A transmission assembly 4 is fixedly connected to the end of the conveyor 1. A gap is provided inside the transmission assembly 4. Detection devices 5 are fixedly installed on both the top and the bottom of the transmission assembly 4, and the detection devices 5 scan the upper and lower surfaces of the backlight through the gap of the transmission assembly 4. A collection box for receiving materials is fixedly connected to the end of the transmission assembly 4.

[0032] As a further description of the embodiment of the present invention, the technical principle of the HUD is optical projection. Therefore, the backlight in the HUD is mostly made of a transparent material with high transparency, and its hardness is relatively low. If it is fixed by clamping, it is easy to damage the backlight during the clamping process, and there will also be a detection dead angle in the clamped part, thus affecting the detection result. In this embodiment, the backlight is placed on the conveyor belt 11, and the conveyor 1 drives the conveyor belt 11 to move to convey the backlight forward. During the forward conveyance of the backlight, it first passes through the first observation assembly 2. The position of the backlight on the conveyor belt 11 is observed through the first observation assembly 2. If it is detected that the backlight is conveyed forward close to or near the edge of the conveyor belt 11, the feeding device 3 is activated to change the traveling direction of the backlight, so that the backlight moves towards the middle position of the conveyor belt 11.

[0033] After the backlight is repositioned by the stock feeding device 3, the second observation component 21 detects the position of the backlight on the conveyor belt 11 again. In cooperation with the adjustment mechanism 6, the backlight is adjusted to the center position of the conveyor belt 11. During this process, the adjustment mechanism 6 first adjusts the two sides of the backlight to be consistent with the conveying direction of the conveyor belt 11, and then moves the backlight to the middle position of the conveyor belt 11. Moreover, the adjustment mechanism 6 moves along with the conveying direction of the conveyor belt 11, so as to reduce the hard friction between the backlight and the conveyor belt 11 during the position adjustment process and avoid frictional loss on the surface of the backlight. Subsequently, the backlight is conveyed by the conveyor belt 11 to the transmission component 4. The detection devices 5 at the upper and lower ends of the transmission component 4 detect the defects on both sides of the backlight through the gaps of the transmission component 4. After the detection is completed, the backlight is conveyed into a collection box (not shown in the figure) through the transmission component 4 for collection, and thus the continuous detection operation of the backlight can be completed.

[0034] As a preferred solution of an HUD backlight debugging device, the adjustment mechanism 6 includes a slide table 61 fixedly installed on the conveyor 1. A cross table 62 is slidably connected to the slide table 61. And a driving device 63 for driving the cross table 62 to reciprocate along the conveying direction of the conveyor belt 11 is arranged in the slide table 61. A moving and lifting component 7 is arranged on the cross table 62. A rotating component 8 is arranged at the bottom of the moving and lifting component 7. A two-way telescopic box 64 is fixedly connected to the bottom of the rotating component 8. Output ends of both ends of the two-way telescopic box 64 are fixedly connected with a pressing plate 65.

[0035] As a preferred solution of an HUD backlight debugging device, a plurality of mounting posts 12 are equidistantly arranged on the conveyor belt 11. Ball bodies 121 are mounted on the tops of the plurality of mounting posts 12 in a universal rotating manner. A hook 66 is fixedly connected to the bottom of the pressing plate 65. And the distance between adjacent mounting posts 12 is greater than the width of the hook 66.

[0036] As a further illustration of the embodiments of the present invention, in this embodiment, the driving device 63 drives the cross table 62 to slide smoothly along the conveying direction of the conveyor belt, so that the adjustment action of the cross table 62 is synchronized with the conveying direction of the backlight. After the position of the backlight is detected by the second observation component 21, the moving and lifting component 7 is started to drive the double telescopic box 64 (the double telescopic box 64 in this embodiment is an existing double screw 72 or a device formed by combining two sets of telescopic devices) to move above the backlight, and then the moving and lifting component 7 drives the double telescopic box 64 to descend, and cooperates with the rotating component 8 to drive the backlight to rotate. Specifically, according to the posture of the backlight detected by the second observation component 21, the moving and lifting component 7 is started in advance to move the double telescopic box 64 above the backlight, and adaptively expand and contract according to the width of the backlight, so that the claw 66 on both sides of the double telescopic box 64 contacts the edge of the backlight at the same time without applying pressure, and then the rotating component 8 is started to drive the double telescopic box 64 to rotate. During the rotation, the claw 66 contacts the side wall of the backlight, so that the backlight rotates together with the claw 66;

[0037] During this process, since the mounting posts 12 and the balls 121 are provided on the conveyor belt 11, the bottom of the backlight contacts the tops of the multiple balls 121. When the backlight rotates and adjusts with the claw 66, the rotation of the balls 121 is used to reduce the friction between the backlight and the tops of the balls 121, avoiding scratches on the back of the backlight. Until the length of the backlight rotates to be consistent with the conveying direction of the conveyor belt 11 (the driving device 63 always drives the cross table 62 to move forward with the conveyor belt during this process to avoid subsequent accumulation of the backlight as the conveyor belt 11 advances), the moving and lifting component 7 is driven to move the backlight to the middle position of the conveyor belt 11, and then the double telescopic box 64 is started to expand the pressing plate 65, so that the pressing plate 65 and the claw 66 are away from the backlight, and the moving and lifting component 7 is started again to drive the double telescopic box 64 to rise and reset, thus completing the position adjustment process of the backlight.

[0038] In addition, the radian setting of the balls 121 enables the backlight to only contact the tops of the balls 121, and the contact area between the backlight and the balls 121 is small, so that the backlight is smoother during the position adjustment process. Through the flexible contact between the backlight and the claw 66 and the sliding displacement of the backlight on the balls 121, the problem of surface scratches on the backlight caused by traditional clamping positioning is solved.

[0039] As a further preferred solution of this embodiment, in this embodiment, when obvious defects are detected on the upper surface of the backlight source by the first observation component 2 or the second observation component 21, the claw 66 can be directly extended into the gap of the mounting post 12 by moving the lifting component 7, and the defective backlight source can be hooked and separated from the conveyor belt 11 in cooperation with the bidirectional telescopic box 64. Subsequently, the defective backlight source can be directly removed manually or by an external device, so that the adjusting mechanism 6 has the function of preliminary screening to relieve the pressure of subsequent defect processing procedures.

[0040] As a preferred solution of an HUD backlight source debugging device, the moving and lifting component 7 includes a shaft frame 71 fixedly installed on the cross table 62. A screw rod 72 is rotatably connected inside the shaft frame 71. The shaft frame 71 is slidably connected with a mounting plate 73 through the screw rod 72. A second motor 74 connected to the screw rod 72 is fixedly connected to the side wall of the shaft frame 71. An air cylinder 75 is fixedly inverted on the top of the mounting plate 73. The output end of the air cylinder 75 is fixedly connected to the rotating component 8.

[0041] As a further illustration of the embodiment of the present invention, in this embodiment, the second motor 74 drives the mounting plate 73 to reciprocate axially along the screw rod 72, which is convenient for adjusting the horizontal position of the bidirectional telescopic box 64. Then, in cooperation with the expansion and contraction of the air cylinder 75, the vertical height of the bidirectional telescopic box 64 is adjusted, so that after the first observation component 2 or the second observation component 21 detects the position of the backlight source on the conveyor belt 11, the bidirectional telescopic box 64 can be driven to move above the backlight source in advance by the moving and lifting component 7, which is convenient for subsequent adjustment of the position of the backlight source on the conveyor belt 11.

[0042] As a preferred solution of an HUD backlight source debugging device, the rotating component 8 includes a gear box 81 fixedly connected to the output end of the air cylinder 75. A rotating shaft 82 is rotatably connected inside the gear box 81. A main bevel gear 83 is sleeved on the rotating shaft 82. A third motor 84 is fixedly connected to the side wall of the gear box 81, and the output end of the third motor 84 extends into the gear box 81 and is fixedly connected with a sub bevel gear 85. The main bevel gear 83 meshes with the sub bevel gear 85. The bottom of the rotating shaft 82 is fixedly connected to the top of the bidirectional telescopic box 64.

[0043] As a further illustration of the embodiment of the present invention, in this embodiment, the third motor 84 drives the sub bevel gear 85 to drive the main bevel gear 83 and the rotating shaft 82 to rotate, thereby driving the rotation of the bidirectional telescopic box 64 fixedly connected to the bottom of the rotating shaft 82. In cooperation with the baffle and the claw 66 at the bottom of the bidirectional telescopic box 64, the bidirectional telescopic box 64 has the effect of driving the backlight source to rotate to be consistent with the conveying direction of the conveyor belt 11. In addition, after the first observation component 2 or the second observation component 21 detects the attitude of the backlight source on the conveyor belt 11, the bidirectional telescopic box 64 is rotated to the same attitude as the backlight source in advance by the rotating component 8, which is convenient for subsequent direction adjustment and moving operations of the bidirectional telescopic box 64.

[0044] As a preferred solution of an HUD backlight debugging device, the transmission component 4 includes a mounting frame 41 fixedly connected to the end of the conveyor 1. A plurality of driving rollers 42 are detachably mounted in the mounting frame 41. The plurality of driving rollers 42 are interconnected by a chain. A fourth motor 43 for driving the driving rollers 42 to rotate is fixedly mounted on the side wall of the mounting frame 41.

[0045] As a further description of the embodiment of the present invention, in this embodiment, by adjusting the spacing between the plurality of driving rollers 42, the driving rollers 42 can adapt to backlights of different models for transmission operations. Specifically, to ensure that the backlight does not slide down along the gap between the two driving rollers 42 during the transmission process on the transmission component 4, it is necessary to ensure that the center of gravity of the backlight is always on one side of the previous driving roller 42. Therefore, the size and spacing of the driving rollers 42 can be adjusted accordingly according to different models of backlights, so that when the front end of the backlight touches the top of the next driving roller 42, the center of gravity of the backlight is still on the previous driving roller 42, avoiding the backlight from tilting downward. In addition, the tightness of the chain can also be adjusted at will, thereby enhancing the usage scenarios of the device. As a further description of the embodiment of the present invention, in this embodiment, the rotation speed of the driving roller 42 should be consistent with the transmission speed of the conveyor belt 11 to avoid wear caused by the speed difference when the backlight is transmitted from the conveyor belt 11 to the driving roller 42.

[0046] As a preferred solution of an HUD backlight debugging device, the detection device 5 includes a first gantry 51 detachably mounted on the top of the mounting frame 41. An industrial camera 52 is fixedly connected to the first gantry 51. The industrial cameras 52 in the two detection devices 5 are distributed oppositely, and the two industrial cameras 52 are located in the gap between the two driving rollers 42.

[0047] As a further description of the embodiment of the present invention, in this embodiment, the upper and lower surfaces of the backlight are finely detected by two oppositely distributed industrial cameras 52 mounted in the gap between the two driving rollers 42. Further, by mounting a ring-shaped LED light supplement module on the industrial camera 52, the reflection interference on the surface of the transparent material can be eliminated. The two oppositely distributed industrial cameras 52 synchronously capture the upper and lower surfaces of the backlight instantaneously when the backlight passes through the gap between the driving rollers 42. And by using the image processing unit in the prior art to compare the dual-view imaging data of the two industrial cameras 52, bubbles inside the backlight or scratches on the surface can be identified. The detection efficiency of the two industrial cameras 52 is significantly improved compared with the single-camera solution. In addition, during the detection process of the device, no occlusion is performed on the periphery of the backlight, and before the backlight enters the detection device 5, it will undergo multi-stage position adjustment by the adjustment component, so that the backlight is always within the detection range of the industrial camera 52, making the detection of the backlight more comprehensive and perfect, and further improving the accuracy of the detection result.

[0048] As a preferred solution of the HUD backlight debugging device, the material pushing device 3 includes two strip plates 31 rotatably mounted on the top of the conveyor. Grooves 13 for mounting the strip plates 31 are provided on both sides of the conveyor, and a fifth motor 32 for driving the strip plates 31 to rotate is mounted on the top of the groove 13.

[0049] As a further description of the embodiment of the present invention, in this embodiment, the surface of the strip plate 31 is covered with an anti-collision layer, so that the strip plate 31 has a buffering effect when contacting the backlight, thereby reducing the risk of friction and collision of the backlight. The strip plate 31 is driven by the fifth motor 32 to rotate and swing. When it is detected that the backlight is against the edge, the strip plate 31 swings to form a guiding inclined plane, so that the backlight is guided by the strip plate 31 and shifted towards the middle position of the conveyor belt 11, which is convenient for the subsequent direction adjustment and movement operation of the claw 66 at the bottom of the double-direction telescopic box 64 on the backlight.

[0050] As a preferred solution of the HUD backlight debugging device, the first observation assembly 2 and the second observation assembly 21 have the same structure. The first observation assembly 2 includes a second gantry 22 fixedly mounted on the top of the conveyor, and a plurality of detection cameras 23 are fixedly mounted on the inner top of the second gantry 22.

[0051] As a further description of the embodiment of the present invention, in the actual configuration of the first observation assembly 2 in this embodiment, the second gantry 22 straddles both sides of the conveyor belt 11, and its truss structure will reserve multiple groups of mounting holes. The detection camera 23 is equipped with an electric zoom lens, which can automatically adjust the field of view according to the size of the backlight. And the pixel deviation between the edge of the backlight and the reference line of the conveyor belt 11 is calculated in real time through an external image processing system. When the offset exceeds the preset threshold, the material pushing device or the adjustment mechanism is immediately triggered, thereby forming a closed-loop control system.
