In some embodiments, the appearance inspection mechanism 300 includes a slider 310, a driver 320, a camera 330, a light source 340, a fixed frame 350, a horizontal line module, and a vertical line module. The sliding block 310 is slidably connected to the beam 210 of the bracket 200, and the sliding block 310 can slide along a first direction relative to the bracket 200, where the first direction is an X-axis direction, that is, a horizontal transverse direction. For example, the cross beam 210 is provided with a guide rail, the guide rail extends along the first direction, the slider 310 may be provided with a guide groove, and the sliding connection between the slider 310 and the cross beam 210 may be realized through the cooperation of the guide rail and the guide groove. The horizontal transverse straight line module is arranged on the cross beam 210, and the sliding block 310 is connected with the horizontal transverse straight line module, so that when the horizontal transverse straight line module works, the sliding block 310 can be driven to slide back and forth relative to the cross beam 210 along a first direction.

When the driver 320 is operated, the camera 330 is also driven to rotate along the axis extending in the third direction, i.e., the Y-axis direction, i.e., the horizontal longitudinal direction. Obviously, the first direction, the second direction and the third direction are perpendicular to each other two by two, and may form an extending direction of three coordinate axes in a space coordinate system. When the driver 320 rotates the camera 330, the lens of the camera 330 can be made to capture images in different directions. The camera 330 may employ a line camera 330 or the like. The driver 320 has a large driving torque, and components such as a reduction gear, a gear box, and a belt can be omitted, thereby simplifying the structure of the entire appearance detecting mechanism 300.
The fixing frame 350 extends in a vertical direction, the upper end of the fixing frame 350 may be fixed on the driver 320, and the light source 340 is disposed at the lower end of the fixing frame 350 such that the light source 340 and the driver 320 are disposed at an interval in the vertical direction, and by disposing the light source 340, when the camera 330 starts to photograph to collect an image, the reality of image collection may be improved in a case where the light source 340 is turned on. When the vertical linear module drives the driver 320 to move downwards, the camera 330, the fixing frame 350 and the light source 340 all move close to the sinking groove 111 on the base 100, so as to move close to the three-dimensional display screen 20 to be detected. The driver 320 is driven by the vertical straight line module to move up and down to be close to or far away from the three-dimensional display screen 20 to be detected, so that the camera 330 can be close to or far away from the three-dimensional display screen 20 to be detected, the function of adjusting the focal length of the camera 330 is finally achieved, and the camera 330 can be ensured to clearly acquire images of all places on the three-dimensional display screen 20.
When the horizontal longitudinal linear module 600 drives the three-dimensional display screen 20 to be detected to move below the appearance detection mechanism 300, the camera 330 can move from one end to the other end relative to the three-dimensional display screen 20 to be detected through the movement of the slider 310 relative to the cross beam 210 in the horizontal direction, so that images of all positions on the three-dimensional display screen 20 are acquired. When the driver 320 is driven by the vertical straight line module to move up and down to be close to or far away from the three-dimensional display screen 20 to be detected, the camera 330 can be close to or far away from the three-dimensional display screen 20 to be detected, the focal length of the camera 330 can be adjusted, and images of all places on the three-dimensional display screen 20 can be clearly acquired by the camera 330. Moreover, when the driver 320 drives the camera 330 to rotate, the normal direction of the lens on the camera 330 can coincide with the normal direction of the surface of the three-dimensional display screen 20, so that the normal direction of the lens of the camera 330 is perpendicular to the tangent plane of the three-dimensional display screen 20, and the definition and the authenticity of the camera 330 for collecting images of all positions of the three-dimensional display screen 20 are also ensured.
For a planar display screen, when the display screen is located at the focal length of the camera 330, after the normal direction of the lens of the camera 330 is ensured to be perpendicular to the normal direction of the display screen, the camera 330 can be moved from one end of the display screen to the other end along a straight line along the same direction to acquire images everywhere on the display screen, and finally, the acquired images are synthesized, so that an acquired image of the whole display screen can be formed, and whether the display screen has defects in appearance or not can be determined by analyzing the acquired image. Therefore, when the display screen is planar, the camera 330 can perform simple linear motion to acquire an image. However, for the three-dimensional display screen 20, because the normal directions of the curved screen of the three-dimensional display screen 20 are different, under the condition that the camera 330 makes a simple linear motion, it cannot be ensured that each image acquisition point of the three-dimensional display screen 20 is located at the focal distance of the camera 330, and it also cannot be ensured that the normal direction of each image acquisition point of the three-dimensional display screen 20 coincides with the normal direction of the lens on the camera 330, so that the definition and the authenticity of the acquired image cannot be ensured.
With the appearance detecting mechanism 300 in the above-described embodiment, first, the camera 330 is directed to each image capturing point on the three-dimensional display screen 20 by the rectilinear motion of the camera 330 in the first direction. Secondly, by the rectilinear motion of the camera 330 in the second direction, the respective image capturing points on the three-dimensional display screen 20 can be located at the focal distance of the camera 330. Thirdly, the driver 320 drives the camera 330 to rotate along the axis extending in the third direction, so that the normal direction of the lens of the camera 330 can coincide with the normal direction of each image acquisition point, the image acquired by the camera 330 at each image acquisition point is clear and real, and finally the definition and authenticity of the synthesized image are ensured, so that various defects of the three-dimensional display screen 20 on the appearance can be accurately identified through the synthesized image, and the accuracy of the detection result of the appearance detection mechanism 300 is improved.
Therefore, for the curved three-dimensional display screen 20, the movement locus of the lens of the camera 330 can be curved by the linear motion of the camera 330 in the first direction and the second direction and the rotation around the third direction, that is, by the combination of two linear motions and one rotation motion, and then the curved movement locus is matched with the curved three-dimensional display screen 20, and finally the definition and the authenticity of the image acquired by the camera 330 are ensured.
In some embodiments, the picture detection mechanism 400 is used to capture images of the display graphics of the three-dimensional display screen 20 for picture detection, and the picture detection mechanism 400 is substantially similar to the appearance detection mechanism 300 in overall structure. Specifically, the frame detection mechanism 400 may include a first guide block 410, a first camera 420, and a first power source 430, where the first guide block 410 is slidably connected to the cross beam 210, so that the first guide block 410 can perform a reciprocating linear motion in a first direction with respect to the cross beam 210. The first power source 430 is slidably disposed on the first guide block 410, the first power source 430 can slide up and down along the second direction relative to the first guide block 410, the first camera 420 is disposed on the first power source 430, and the first power source 430 can drive the first camera 420 to rotate along the axis extending in the third direction. When the horizontal longitudinal linear module 600 drives the three-dimensional display screen 20 to be detected to move below the picture detection mechanism 400, through the horizontal linear motion of the first guide block 410 relative to the cross beam 210, each image acquisition point on a display graph of the three-dimensional display screen 20 can be covered by the first camera 420, meanwhile, the first camera 420 makes reciprocating linear motion in the second direction along with the first power source 430, each image acquisition point can be located on the focal length of the first camera 420, and when the first power source 430 drives the first camera 420 to rotate around the third direction, the normal direction of the first camera 420 can be the same as the normal direction of each acquisition point on the three-dimensional display screen 20, so that the definition and the authenticity of image acquisition are ensured, and the accuracy of a detection result is ensured.
In some embodiments, the backlight detection mechanism 500 is used to capture an image of the backlight module of the three-dimensional display screen 20 for backlight detection, and the backlight detection mechanism 500 is substantially similar to the appearance detection mechanism 300 in overall structure. Specifically, the backlight detecting mechanism 500 may include a second guide block 510, a second camera 520, and a second power source 530, where the second guide block 510 is slidably connected to the beam 210, so that the second guide block 510 can perform a reciprocating linear motion in a second direction with respect to the beam 210. The second power source 530 is slidably disposed on the second guide block 510, the second power source 530 can slide up and down along the second direction relative to the second guide block 510, the second camera 520 is disposed on the second power source 530, and the second power source 530 can drive the second camera 520 to rotate along the axis extending in the third direction.

In some embodiments, the rack 200, the appearance detection mechanism 300, the picture detection mechanism 400, and the backlight detection mechanism are all housed in the cabinet 700, which can be protected by the cabinet 700. Meanwhile, a part of the base 100 is received in the cabinet 700, and another part of the base 100 is located outside the cabinet 700, so that a part of the sink 111 is not covered by the cabinet 700 and is exposed outside the cabinet 700, and the part exposed outside the cabinet 700 is the exposed section 111 a. When the three-dimensional display screen 20 needs to be detected, the three-dimensional display screen 20 can be placed on the jig from the position corresponding to the exposed section 111a, so that the three-dimensional display screen 20 to be detected is input into the detection device 10, and the horizontal and longitudinal linear module 600 drives the three-dimensional display screen 20 to be detected to move to the positions below the appearance detection mechanism 300, the picture detection mechanism 400 and the backlight detection mechanism for detection. After the appearance detection, the image detection and the backlight detection are completed, the horizontal and longitudinal linear module 600 drives the three-dimensional display screen 20 to be detected to return to the exposed section 111a again, so that the detected three-dimensional display screen 20 is output from the whole detection device 10.
Because the appearance detection mechanism 300, the picture detection mechanism 400 and the backlight detection mechanism 500 are all integrally arranged on the bracket 200, the detection device 10 can simultaneously perform appearance detection, picture detection and backlight detection on the three-dimensional display screen 20, and the detection function of the detection device 10 is ensured to be diversified. Moreover, the appearance detection mechanism 300, the picture detection mechanism 400 and the backlight detection mechanism 500 are integrated, so that the structure of the detection device 10 can be simplified, the volume and the occupied space can be reduced, and the three-dimensional display screen 20 can be prevented from being transferred among different detection devices to realize the detection of different items, so that the intermediate transfer and waiting time can be saved, and the detection efficiency can be improved.
