Description

Technical Field

[0001] This application relates to the field of glass detection equipment, and particularly to a device for automatically measuring the deviation of glass secondary images. Background Art

[0002] The automotive windshield is an important part of the vehicle safety system. It is not only a component for protecting against wind and rain, but its optical properties are also related to the safety of drivers and passengers.

[0003] The secondary image deviation angle is a core data for measuring the optical properties of the windshield. Among them, secondary image deviation refers to the phenomenon that when the two surfaces of the glass are not parallel, under certain lighting conditions, when looking at an object through the glass, in addition to the main image (the target object within the line of sight), one or more secondary images (commonly known as shadows) will also be seen. The angle formed between the secondary image and the main image is called the secondary image deviation angle. When driving at night, in the dark background, the secondary images caused by bright lights are very obvious. If the secondary image deviation angle is large, the driver will have an illusion and it is easy to cause traffic accidents. Therefore, the detection of the secondary image deviation angle of the windshield is very important.

[0004] However, in the process of implementing the present invention, it is found that in the prior art, the measurement of the secondary image deviation angle of the windshield is manually marked with measurement points and manually measured, resulting in large measurement errors, low repeatable measurement accuracy, slow detection speed, and thus low production efficiency and high production costs.

[0062] As Figures 1 - 3As shown in the figure, an embodiment of the present application provides a device for automatically measuring the deviation of a glass secondary image, including:

[0063] An outer frame 1, an inner frame 2, a detection unit 4, and a driving unit 5;

[0064] The inner frame 2 is placed in the outer frame 1 and is rotatably connected to the outer frame 1. The inner frame 2 can rotate horizontally relative to the outer frame 1 and is used to place the glass 3 to be detected. On both sides of the detection unit 4, there are respectively a light source 41 and a light and shadow collector 42. The light source 41 and the light and shadow collector 42 are opposite to each other, and the light source 41 and the light and shadow collector 42 are respectively suspended on both sides of the inner frame 2 and are located on both sides of the glass 3 to be detected. The driving unit 5 is connected to the top of the outer frame 1 and is connected to the middle of the detection unit 4;

[0065] Wherein, the driving unit 5 can drive the detection unit 4 to reciprocate in a first direction parallel to the rotation axis of the inner frame 2, and drive the detection unit 4 to reciprocate and rotate with the first direction as the axis; the driving unit 5 can drive the detection unit 4 to reciprocate in the vertical direction, and can drive the detection unit 4 to reciprocate and rotate with the vertical direction as the axis.

[0066] Specifically, the outer frame 1 is a frame for supporting the entire device. The outer frame 1 can be a rectangular frame 21 as a whole or a frame of other shapes. The outer frame 1 needs to have a certain strength and can be made of metal materials to make it have a certain supporting and bearing capacity. For example, a rectangular frame 21 formed by connecting aluminum profiles with screws or rivets, as Figure 1 shown, all four sides of it can be rectangular frames 21, so that it can have good support and can be stably placed vertically. The accommodation space in the middle of the outer frame 1 is used to place and connect the inner frame 2, and its top is a horizontal support beam, which can be used to install the detection unit 4. The bottom of the outer frame 1 can also be connected with rollers, for example, universal wheels with brakes, so as to achieve the convenient movement effect of the entire device through the universal wheels.

[0067] The inner frame 2 is a structure for placing the glass 3 to be detected. Its outer shape needs to be adapted to the internal space of the outer frame 1 to ensure that after the inner frame 2 is installed in the outer frame 1, it can rotate normally without interference. For example Figure 1As shown, the inner frame 2 can be a rectangular frame 21, and the inner space of the frame can place the glass 3 to be detected. Its shape is suitable for rotatably connecting with the outer frame 1, and the inner frame 2 and the outer frame 1 can also be automatically adjusted for the rotation angle of the inner frame 2 in a motor-driven manner. The inner frame 2 also needs to have a certain strength, and considering the overall cost of the device, the inner frame 2 preferably uses the same material and the same connection means as the outer frame 1. For example, the inner frame 2 can also be formed by connecting aluminum profiles with screws or rivets.

[0068] The detection unit 4 needs to have a light source 41 and a light and shadow collector 42, and can make the light source 41 and the light and shadow collector 42 located on both sides of the inner frame 2. For example, the main body of the detection unit 4 has a support structure, and the light source 41 and the light and shadow collector 42 are oppositely arranged through the support structure, and the overall driving of the light source 41 and the light and shadow collector 42 can be achieved by driving the support structure. Among them, the light source 41 can be a laser light source 41, and the light and shadow collector 42 is a camera with a camera for collecting light and shadow. The light-emitting end of the light source 41 needs to be aligned with the collecting end of the light and shadow collector 42.

[0069] The driving unit 5 is a structure for driving the movement of the detection unit 4, and it can realize the movement driving of the detection unit 4 through the cooperation of multiple driving motors plus a movement structure or multiple driving units. The driving unit 5 can be fixed on the top of the outer frame 1, then connected to the detection unit 4, and realize the driving of the detection unit 4, and as long as it is ensured that the driving of the detection unit 4 can achieve horizontal movement, vertical movement, horizontal rotation and vertical rotation.

[0070] The driving unit 5, the light source 41 and the light and shadow collector 42 can all be controlled by the same controller. For example, it can be controlled by a computer or by a separate processor. This application does not make specific limitations. The control program and control logic of the device for automatically measuring the deviation of the glass secondary image can be obtained by technicians through simple programming, and this application does not make limitations.

[0071] The device for automatically measuring the deviation of the glass secondary image provided by the embodiment of this application has the following working principle and usage method:

[0072] First, rotate the inner frame 2 relative to the outer frame 1 to an appropriate angle, that is, the placement angle required when the glass 3 to be detected is detected. For example, 0 - 80 degrees (the angle between the glass 3 to be detected and the vertical direction), and then place the glass 3 to be detected in the middle accommodating space of the inner frame 2. At this time, the placement work of the detection sample is completed, and the rotation angle of the inner frame 2 can be adjusted in real time according to the detection needs, that is, the placement angle of the glass 3 to be detected is adjusted to simulate the working state of the actual glass 3 to be detected.

[0073] Afterwards, since the light source 41 and the light and shadow collector 42 of the detection unit 4 are oppositely arranged and are respectively located on both sides of the glass 3 to be detected, at this time, the driving unit 5 is used to control the movement of the detection unit 4, so that the light source 41 and the light and shadow collector 42 move to the detection points of the glass 3 to be detected, and the driving unit 5 is driven to make the light emitted by the light source 41 perpendicular to or at a preset angle with the detection points of the glass 3 to be detected. Then, the light and shadow collector 42 is used to collect the light and shadow passing through the glass and the deviated secondary image, and the detection result is transmitted to a computer or a processor through data transmission, and the computer or the processor calculates to obtain the secondary image deviation angle.

[0074] It can be seen that the device for automatically measuring the deviation of the secondary image of the glass provided by the present application has an inner frame 2 and an outer frame 1 that can rotate relative to each other. The inner frame 2 is for placing the glass 3 to be detected. The inner frame 2 can adjust the placement angle of the glass 3 to be detected by rotating relative to the outer frame 1 to simulate the working angle of the glass 3 to be detected in actual application. The device for automatically measuring the deviation of the secondary image of the glass also has a detection unit 4 and a driving unit 5. The detection unit 4 has a light source 41 and a light and shadow collector 42, and the light source 41 and the light and shadow collector 42 are suspended on both sides of the glass 3 to be detected, so that the light emitted by the light source 41 can irradiate on the glass 3 to be detected, and the light and shadow collector 42 can collect the image of the light source 41 passing through the glass 3 to be detected and the secondary image of the light source 41. Then, the deviation angle of the secondary image of the corresponding detection point of the glass 3 to be detected can be obtained through calculation. The driving unit 5 can drive the detection unit 4 to perform horizontal movement, vertical movement, horizontal rotation and vertical rotation. Furthermore, the light source 41 and the light and shadow collector 42 located on both sides of the glass 3 to be detected can perform horizontal movement, vertical movement, horizontal rotation and vertical rotation, so as to automatically detect the deviation angles of the secondary images of different tilt angles and different positions of the glass 3 to be detected. It not only has relatively high detection accuracy compared with manual detection, but also can achieve high-precision repeated measurement, and has high detection efficiency, thereby effectively reducing the detection cost.

[0075] As Figure 4 and Figure 5 As shown, in a specific implementation, two first bearing gears 11 are connected between the opposite outer walls of the inner frame 2 and the opposite inner walls of the outer frame 1. The inner ring of the first bearing gear 11 is fixedly connected to the outer frame 1, and the outer ring of the first bearing gear 11 is fixedly connected to the inner frame 2.

[0076] Among them, a first driving motor 12 is arranged on the outer frame 1, and the first driving motor 12 is meshed with one of the two first bearing gears 11 through a first driving gear 13.

[0077] Specifically, the inner ring and the outer ring of the bearing gear refer to two rings that can rotate relative to each other. The outer ring is provided with teeth and is thus a gear. By fixing the inner ring on the inner wall of the outer frame 1, the first bearing gear 11 is fixed on the outer frame 1. By fixing the outer ring to the outer wall of the inner frame 2, the first bearing gear 11 is connected to the inner frame 2. At this time, the inner frame 2 and the outer frame 1 can rotate relative to each other through the first bearing gear 11. Further, by drivingly connecting the first driving motor 12 with the first bearing gear 11, the first bearing gear 11 can be driven by the first driving motor 12 to drive the inner frame 2 to rotate. The rotation angle of the inner frame 2 can be controlled by the first driving motor 12 according to the detection angle requirement of the glass 3 to be detected. The control of the first driving motor 12 can be achieved through an external computer or a processor independently provided on the device for automatically measuring the deviation of the glass secondary image.

[0078] As Figure 4 and Figure 5 shown, further, the device for automatically measuring the deviation of the glass secondary image provided by the embodiment of the present application further includes: a first limiter 14 and a second limiter 15. Both the first limiter 14 and the second limiter 15 are installed on the inner wall of the outer frame 1 and are located near the position where the inner frame 2 is rotationally connected to the outer frame 1.

[0079] Wherein, taking the position where the inner frame 2 is rotationally connected to the outer frame 1 as the corner point, the included angle formed by connecting the first limiter 14 and the second limiter 15 respectively is 80 degrees, which is used to limit the rotation of the inner frame 2 within the range from the vertical position to the position with an included angle of 80 degrees with the vertical position.

[0080] Specifically, since the inclination angle of the glass 3 to be detected with respect to the vertical direction during operation is 0 - 80 degrees, in order to enable the device for automatically measuring the deviation of the glass secondary image provided by the present application to simulate the actual working angle, the first limiter 14 and the second limiter 15 are used in cooperation to limit the rotation angle of the inner frame 2. Among them, the first limiter 14 and the second limiter 15 can be two pairs, which are respectively arranged on the two inner side walls of the outer frame 1 and are near the position where the inner frame 2 is rotationally connected to the outer frame 1. The limiter can be a limiter with a damping function or a rigid limiter.

[0081] As Figure 4 and Figure 5As shown, in a specific implementation, the inner frame 2 includes a rectangular frame 21 and an upper adjusting beam 22; the rectangular frame 21 is formed by two vertical beams 211 and two cross beams 212 sequentially spaced around, and the two vertical beams 211 are respectively rotatably connected to the outer frame 1; the two ends of the upper adjusting beam 22 are respectively movably connected to the inner walls of the two vertical beams 211, and the upper adjusting beam 22, the cross beam 212 close to the bottom among the two cross beams 212 and the two vertical beams 211 form a space for placing the glass 3 to be detected.

[0082] Specifically, the inner frame 2 is a rectangular frame 21, and the rectangular frame 21 can be formed by screw connection or rivet connection of aluminum profiles, such as Figure 1 As shown, the two vertical beams 211 of the rectangular frame 21 are rotatably connected to the inner walls on both sides of the outer frame 1. The two ends of the upper adjusting beam 22 can be movably connected to the two vertical beams 211 on both sides by hand-tightening screws, and a plurality of threaded holes can be added along the length direction on the two vertical beams 211 for adaptation. Furthermore, by matching the hand-tightening screws with different threaded holes, the position of the upper adjusting beam 22 can be adjusted, that is, the position of the upper adjusting beam 22 in the inner frame 2 can be adjusted adaptively according to the height of the glass 3 to be detected, so that the placement space formed by the upper adjusting beam 22, the cross beam 212 close to the bottom among the two cross beams 212 and the two vertical beams 211 can be suitable for placing glasses 3 to be detected with different sizes.

[0083] Furthermore, as Figure 4 and Figure 5 shown, the inner frame 2 further includes: a lower adjusting beam 23, a plurality of clamping grooves 24 are oppositely arranged on the inner walls of the two vertical beams 211, and the lower adjusting beam 23 is detachably clamped with the clamping grooves 24; wherein, the lower adjusting beam 23, the upper adjusting beam 22 and the two vertical beams 211 form a space for placing the glass 3 to be detected.

[0084] Specifically, the clamping groove 24 can be in the form of a sliding groove, that is, the groove body is U-shaped, and a stop block or a stop strip is arranged for the sliding groove on one side of the inner frame 2. The side where the stop block or the stop strip is arranged is on the side where the inner frame 2 rotates in the direction of increasing the angle with the vertical direction. At this time, the lower adjusting beam 23 can adopt a rectangular aluminum profile so that its two ends can be adaptively connected and disassembled with the clamping grooves 24 on both sides of the outer frame 1. Among them, the clamping grooves 24 are a plurality of continuously arranged ones. Through the arrangement of the clamping grooves 24, the position of the lower adjusting beam 23 can be finely adjusted, and then the placement space of the glass 3 to be detected formed by the lower adjusting beam 23, the upper adjusting beam 22 and the two vertical beams 211 can be adjusted, so as to ensure the detection of the glass 3 to be detected with a smaller height.

[0085] As Figure 4 and Figure 5As shown, in a specific implementation, the inner frame 2 further includes: a right-angle support plate 25. At least one of the right-angle support plates 25 is installed on one side of the upper adjustment beam 22 relative to the lower adjustment beam 23, and at least one of the right-angle support plates 25 is installed on one side of the lower adjustment beam 23 relative to the upper adjustment beam 22. The right-angle support plates 25 on the upper adjustment beam 22 and the lower adjustment beam 23 form a supporting portion for supporting the glass 3 to be detected.

[0086] Specifically, the right-angle support plate 25 can be a long strip having the same length as the upper adjustment beam 22 and the lower adjustment beam 23, or can be a plurality of right-angle support plates 25 spaced apart on the upper adjustment beam 22 and the lower adjustment beam 23, as long as it is ensured that the right-angle support plate 25 can stably support the glass 3 to be detected. Among them, after the right-angle support plate 25 is connected to the upper adjustment beam 22 and the lower adjustment beam 23, its opening side is located on the side where the inner frame 2 rotates in the direction of decreasing the angle with the vertical direction, and one side of the right-angle support plate 25 needs to be flush with the side where the inner frame 2 rotates in the direction of increasing the angle with the vertical direction.

[0087] As Figures 1 - 3 、 Figure 6 and Figure 7 As shown, in a specific implementation, the detection unit 4 further includes: a U-shaped frame 43. The U-shaped frame 43 has an opening facing downward. The end portions of the two side walls of the U-shaped frame 43 are respectively connected to the light source 41 and the light and shadow collector 42, and the middle portion of the bottom wall of the U-shaped frame 43 is connected to the driving unit 5.

[0090] The first linear drive unit 51 is arranged parallel to the first direction at the top of the outer frame 1. The second linear drive unit 52 is arranged vertically. The moving drive member 512 of the first linear drive unit 51 is connected to the guiding drive member 521 of the second linear drive unit 52. The first linear drive unit 51 can drive the second linear drive unit 52 to reciprocate parallel to the first direction. The bottom of the moving member 522 of the second linear drive unit 52 is connected to the second drive motor 53. The moving member 522 of the second linear drive unit 52 can drive the second drive motor 53 to reciprocate vertically under the drive of the guiding drive member 521. The second drive motor 53 is connected to the third drive motor 54 through the second bearing gear 55. The second drive motor 53 drives the second bearing gear 55 through the fourth drive gear 57 to drive the third drive motor 54 to reciprocally rotate about the vertical axis. The third drive motor 54 is connected to the detection unit 4 through the third bearing gear 56. The third drive motor 54 drives the third bearing gear 56 through the fifth drive gear to drive the detection unit 4 to reciprocally rotate about the first direction axis.

[0091] Specifically, the first linear drive unit 51 includes a guiding member 511 (such as a guide rail) and a moving drive member 512. The moving drive member 512 includes a slider and a drive motor. The guiding member 511 is fixedly arranged parallel to the first direction at the top of the outer frame 1. The guiding member 511 can be a guide rail with a rack. The drive motor is arranged on the slider. The slider is slidably connected to the guide rail. The drive motor is meshed with the rack in the guide rail through the second drive gear. Thus, through the drive of the drive motor, the drive motor can drive the slider to reciprocate on the guiding member 511. Thus, when the slider of the moving drive member 512 is connected to the second linear drive unit 52, it can drive the second linear drive unit 52 to reciprocally move horizontally.

[0092] The second linear drive unit 52 includes a guiding drive member 521 and a moving member 522 (i.e., a track). The guiding drive member 521 includes a chute and a drive motor.

The track vertically enters the chute and is slidably connected to the chute. A rack is arranged on the side wall of the track. The drive motor is meshed with the rack of the track through the third drive gear. Thus, the moving member 522 (i.e., the track) can be driven to reciprocally move vertically relative to the chute.

[0095] Specifically, the panoramic positioning camera 6 can be detachably arranged from the outer frame 1, or the panoramic positioning camera 6 can be fixed on the outer frame 1 through a connecting body.

[0096] Among them, the panoramic positioning camera 6 is used to photograph the glass 3 to be detected before detecting the glass 3 to be detected, so as to obtain the position information of the glass 3 to be detected and the position of the detection part 4 in real time, especially to obtain the position of the light source 41. Then, the obtained position information is sent to the processor, and the processor can drive the detection part 4 to move and / or rotate according to the set detection points, so that the light source 41 and the light and shadow collector 42 move to the detection position, and based on the position of the detection part 4 photographed by the panoramic positioning camera 6 in real time, the movement position of the detection part 4 is adjusted to ensure that the detection part 4 is accurately in the detection position, thereby realizing accurate detection.
