Description

Technical Field

[0001] The present invention relates to the technical field of notebook computer testing, and more particularly to a highly integrated testing device for a notebook computer camera, a light and a screen. Background Art

[0002] Laptop screens are an important part of modern computers and are usually divided into LCD screens and OLED screens. Modern laptop screen panels are usually also equipped with cameras to enhance user interaction experience. To ensure the quality of the screen panel, the laptop's camera, screen effects, etc. need to be tested before the laptop leaves the factory.

[0003] At present, when testing laptop cameras, screen display brightness and color accuracy, highly integrated testing equipment is usually used, that is, multiple screen, panel, back cover and camera tests can be performed at a single time. When testing a large number of laptops, in order to ensure test consistency, it is usually necessary to keep the probe of the testing equipment at a certain angle, and adjust the opening and closing angle of the laptop screen panel through an angle calibration mechanism to make the laptop back cover or screen fit vertically with the testing probe.

[0004] In the prior art, during the inspection process of the back panel, color accuracy, screen brightness, etc., the screen panel of the laptop to be tested is usually opened and closed to a larger angle, and then the screen panel is pushed by an angle calibration mechanism to adjust the angle to cooperate with the probe for calibration. However, the hinges of existing laptops are mostly damping hinges. When the calibration angle difference is small, the pushing force and stroke of the angle calibration mechanism are low, which may cause the force to be unable to break through the damping static friction of the hinge, resulting in the hinge not rotating relatively. Moreover, since the screen panel material is mostly plastic, the screen panel uses deformation to offset this part of the thrust at this time, which makes it difficult for the screen to match and calibrate with the probe of the detection equipment, bringing inconvenience to the detection accuracy.

[0043] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0044] Embodiment 1:

[0045] In one embodiment of the present invention, a highly integrated testing device for a laptop camera, light and screen is disclosed. Figure 1 , Figure 7-Figure 16As shown, it includes: a body 1; a loading assembly, which is arranged in the body 1, and the loading assembly includes a plurality of slide rails 2 fixedly connected to the inside of the body 1, and the slide rails 2 are connected to the body 1 by welding, bolting, etc., and a carrier bottom plate 21 is slidably connected to the surface of the slide rails 2, and the slide rails 2 are connected to the carrier bottom plate 21 through a first driving mechanism, and a carrier plate 211 is installed on the surface of the carrier bottom plate 21, and a notebook body 23 is arranged on the surface of the carrier plate 211, and the carrier plate 211 is used to carry the notebook body 23, and its size is larger than the notebook body 23, and the notebook body 23 can be a variety of different screen sizes, such as 13 inches, 15 inches, and 17 inches, etc.;

[0046] A positioning assembly is arranged on the surface of the carrier bottom plate 21. The positioning assembly includes a support frame 4 fixedly connected to the surface of the carrier bottom plate 21. The support frame 4 is "U"-shaped. A push plate 41 is slidably connected to the top of the support frame 4. The support frame 4 is connected to the push plate 41 through a second driving mechanism. One end of the push plate 41 close to the notebook body 23 is rotatably connected to a positioning roller 411 for directly contacting the notebook shell. The positioning roller 411 is a rubber-coated roller, and the surface is coated with materials such as rubber or silicone to avoid damage to the notebook shell. Both sides of the push plate 41 are fixedly connected to a connecting frame 43. One end of the connecting frame 43 is fixedly connected to a bracket 431. The width of the bracket 431 is greater than the width of the notebook being measured. The inner wall of the bracket 431 is rotatably connected to a push plate 44. The hinged position of the push plate 44 and the bracket 431 is adapted to the position of the rotating shaft of the notebook computer. The bracket 431 is connected to the push plate 44 through a third driving mechanism.

[0047] The test board 34 is arranged in the body 1, and the body 1 is connected to the test board 34 through a three-axis adjustment component. A visual camera 341 and a screen detection probe 342 are respectively installed on the surface of the test board 34. The visual camera 341 and the screen detection probe 342 are installed on the surface of the test board 34 by bolt fastening. The top and bottom of the screen detection probe 342 are installed with displacement sensors 343 for determining the position of the notebook screen. The displacement sensor 343 is fixed to the surface of the screen detection probe 342 by bolt fastening. When the two displacement sensors 343 detect that the relative screen distance values ​​are the same, the propulsion plate 41 stops propulsion and maintains.

[0048] Specifically, the screen back panel of the notebook body 23 to be tested is unfolded and placed on the surface of the carrier 211. The specific unfolding angle is greater than 120 degrees. The carrier bottom plate 21 is driven by the first driving mechanism to slide on the surface of the slide rail 2 to the test position. Then the visual camera 341 and the screen detection probe 342 follow the test board 34 and are adjusted to the test position by the three-axis adjustment component. The distance to the screen is synchronously sensed by the dual displacement sensor 343. When the perceived distance values ​​of the two are different, the positioning component pushes the screen back panel forward, thereby pushing the screen to a position parallel to the screen detection probe 342. After the values ​​of the dual displacement sensors 343 are the same, the positioning component stops running and maintains. At this time, the three-axis adjustment component adjusts the screen detection probe 342 to be attached to the screen surface. During the entire adjustment process, the dual displacement sensor 343 always detects the motion path and The screen detection probe 342 is an optical sensor probe with an integrated light sensor, which is attached to the surface of the notebook screen and collects screen light through the optical probe, and performs color and color accuracy analysis and comparison, and then obtains the detection result. The light sensor can be used to sense the overall luminous brightness of the screen, the luminous brightness of each channel, and obtain the detection result. The visual camera 341 performs visual detection on the camera performance of the notebook. The visual camera 341 detects the shape, texture, integrity and other shapes of the camera through image recognition and comparison. At the same time, a light source can be integrated in the visual camera 341 to illuminate the camera through the light source, so that the visual camera 341 can detect the reflection of the camera under strong light and other working conditions.

[0049] It is worth noting that when the positioning component pushes the screen back panel, and the screen back panel cannot be parallel to the screen detection probe 342 due to the damping of the rotating shaft, the propulsion distance, etc., the movable rod 434 is driven to rotate by the motor D433, and then the driving wheel 435 is driven to rotate, and the driven wheel 441 engaged with it is rotated to drive the push plate 44 to rotate. Since the push plate 44 is located at the rotating shaft of the notebook body 23, compared with pushing from the screen back panel far away from the rotating shaft, the push plate 44 close to the rotating shaft has a smaller circular path when rotating at the same angle. Therefore, it is more suitable for fine-tuning the screen back panel, and is suitable for fine-tuning situations where the error between the screen back panel angle and the test reference angle is small. In addition, since the push plate 44 directly pushes the panel near the rotating shaft, it can also effectively avoid the situation where the deformation of the screen back panel shell offsets the thrust due to the long force arm during pushing, thereby reducing the rotation error of the screen back panel of the notebook body 23 and improving the fit accuracy between it and the screen detection probe 342.

[0050] like Fig.10 , Fig.11 and Fig.12As shown, in this embodiment, the third driving mechanism includes a protective shell 432 fixedly connected to one side of the bracket 431, and a motor D433 is fixedly connected inside the protective shell 432. The motor D433 is a servo motor, and two movable rods 434 are fixedly connected to the output end of the motor D433. The two movable rods 434 are symmetrical along the center of the output shaft of the motor D433. The inner wall of the protective shell 432 is rotatably connected to a driving wheel 435 relative to the output end of the motor D433. The surface of the driving wheel 435 is provided with two arc holes adapted to the movable rods 434, and the movable rods 434 are penetrated into the arc holes. A driven wheel 441 is fixedly connected to one end of the hinge shaft between the push plate 44 and the bracket 431, and the driven wheel 441 is located in the protective shell 432, and a plurality of teeth are provided on the surfaces of the driven wheel 441 and the driving wheel 435, and they mesh with each other.

[0051] Specifically, through the output of motor D433, the two movable rods 434 are driven to rotate along the motor output shaft. After the movable rod 434 moves to a position against one end of the inner wall of the arc-shaped hole, it will drive the driving wheel 435 to rotate, and then drive the driven wheel 441 engaged with it to rotate. It should be noted that the diameter of the driven wheel 441 is larger than the diameter of the driving wheel 435. The large driven wheel 441 is driven to rotate by the small driving wheel 435, which reduces the rotation speed of the driven wheel 441 and increases its rotation torque, so that the push plate 44 can push the screen panel at the notebook hinge for rotation adjustment.

[0052] Furthermore, an auxiliary plate 442 is fixedly connected to the top of the pushing plate 44, and a plurality of suction cups 443 are fixedly connected to the surface of the auxiliary plate 442, and the opening of the suction cup 443 is facing the direction of the notebook. A connecting tube 444 is provided on the side of the auxiliary plate 442 away from the suction cup 443, and the plurality of suction cups 443 are connected to the connecting tube 444 and are interconnected. An air valve 445 is fixedly connected to the surface of the connecting tube 444, and the opening of the air valve 445 at one end away from the connecting tube 444 is connected to an external air source device. A plurality of contact switches 436 are fixedly connected to the surface of the driving wheel 435. Under normal conditions, the movable rod 434 will contact the contact switch 436, and the air valve 445 is in a closed state at this time, so the suction cup 443 will not be adsorbed on the surface of the notebook shell. A controller is also installed in the shell, and the controller is respectively connected to the motor D433, the air valve 445 and the contact switch 436.

[0053] Specifically, through the arrangement of a plurality of suction cups 443, the suction cups 443 will follow the pushing plate 44 and come close to the surface of the notebook screen shell when the positioning assembly is pushed forward. When the notebook screen shell is pushed to a point smaller than the test angle, it cannot be pushed further and needs to be pulled outward to expand the angle. Accordingly, the motor D433 needs to rotate in the opposite direction, thereby driving the movable rod 434 away from the contact switch 436 and canceling the contact with the contact switch 436. At this time, the contact switch 436 is triggered and transmits a signal to the controller. The controller controls the air valve 445 to open and draws out the air in the connecting pipe 444 and the suction cup 443 through the external air source device to form a negative pressure. The suction cup 443 can be adsorbed on the surface of the notebook screen shell. Due to the redundant setting of the arc hole, when the motor D433 drives the movable rod 434 to reverse, the active wheel 435 will not rotate, thereby leaving redundant time for the suction cup 443 to adsorb the surface of the notebook screen shell. After the suction cup 443 is completely adsorbed, the movable rod 434 also rotates to the inner wall of the other end of the arc hole and abuts against it, thereby driving the active wheel 435 to reverse, and cooperate with the driven wheel 441 engaged with it to reverse, so that the push plate 44 is reversed and the notebook screen shell is pulled outward through the suction cup 443, so that the opening and closing angle is expanded, and it is opened and closed to the test angle, thereby improving the applicability of the positioning device.

[0054] like Figure 8 As shown, in this embodiment, the visual camera 341, the screen detection probe 342 and the two displacement sensors 343 are all tilted at a certain angle relative to the test board 34, and the tilt angle is greater than 25 degrees, and the two displacement sensors 343 are parallel to the screen detection probe 342. The two displacement sensors 343 are used to detect the distance to the screen, so as to determine whether the screen is parallel to the screen detection probe 342, and a reference point can be added to the displacement sensor 343. After the displacement sensor 343 moves to the reference point position, it means that the screen detection probe 342 is in contact with the screen.

[0055] The first driving mechanism includes a motor B22 fixedly connected between two relative slide rails 2, wherein the surface of one of the slide rails 2 is rotatably connected to two synchronous wheels 221, wherein one of the synchronous wheels 221 is axially fixedly connected to the output end of the motor B22, and a synchronous belt 222 is transmission-connected between the two synchronous wheels 221, and the output of the motor B22 drives one of the synchronous wheels 221 to rotate, and then cooperates with the other synchronous wheel 221 to drive the synchronous belt 222, and a connecting block 223 is fixedly connected to the bottom of the carrier base plate 21, and the connecting block 223 is fixedly connected to the synchronous belt 222, and the transmission of the synchronous belt 222 can drive the connecting block 223 to move synchronously, thereby causing the carrier base plate 21 on the surface of the slide rail 2 to move on the surface of the slide rail 2, driving the notebook body 23 to move to the test position, and also includes a synchronization component for positioning the notebook body 23.

[0056] Further, such as Fig.14 , Fig.15 and Fig.16 As shown, in this embodiment, the synchronization component includes two side limit plates 213 sliding on both sides of the carrier 211, the side limit plates 213 are "L"-shaped, and the opposite sides of the two side limit plates 213 are fixedly connected with racks A214, the two racks A214 are parallel to each other but do not overlap, and the teeth on the surfaces of the two racks A214 are arranged opposite to each other, and a motor A215 is fixedly connected to the bottom of the carrier base plate 21, and a gear A216 is fixedly connected to the output end of the motor A215, and the gear A216 is respectively engaged with the two racks A214.

[0057] Furthermore, a front baffle 212 is fixedly connected to the surface of the carrier plate 211 .

[0058] Specifically, after placing the notebook body 23 on the surface of the carrier 211, the front end of the notebook body 23 is abutted against the surface of the front baffle 212, and then the output of the motor A215 drives the gear A216 to rotate, and then cooperates with the two racks A214 meshing with the gear A216 to bring the two side limit plates 213 on both sides close to each other and clamp the two sides of the notebook body 23.

A lifting part is arranged between adjacent conveyor belts 715, and the lifting part includes a connecting seat 72 which slides up and down on the surface of the base 7. The surface of the connecting seat 72 is slidably connected with a guide frame 73, and the guide frame 73 is passed between two adjacent conveyor belts 715. Under normal conditions, the top height of the guide frame 73 is below the surface of the conveyor belt 715 to avoid obstruction to the notebooks conveyed on the surface of the conveyor belt 715. It also includes a driving part for driving the guide frame 73 to slide on the surface of the connecting seat 72, and the connecting seat 72 to slide on the surface of the base 7.

[0066] Specifically, different from the loading method of the first embodiment, in this embodiment, the notebook can be continuously loaded, and the notebook is opened at a certain angle and placed on the surface of the conveyor belt 715. As the conveyor belt 715 continues to run, the notebook can be continuously placed. A loading mechanism can be set on one side of the conveyor belt 715, and a discharging mechanism can be set on the other side of the conveyor belt 715. The loading or unloading is continuously performed by a manipulator, thereby increasing the loading and unloading speed and the detection speed to a certain extent. Subsequently, when the notebook moves above the guide frame 73, the conveyor belt 715 can be suspended, and the guide frame 73 can be lifted by the driving unit so that it lifts the notebook upward until it is no longer in contact with the conveyor belt 715. Subsequently, the driving unit drives the guide frame 73 to move horizontally on the surface of the connecting seat 72 to a predetermined detection position, and further detection is performed.

[0067] The driving unit includes a motor H721 fixedly connected to the bottom of the base 7, and a lifting screw 722 is fixedly connected to the output end of the motor H721. The lifting screw 722 is threadedly connected to the connecting seat 72.

The connecting seat 72 is fixedly connected to the belt C733. When the output of the motor I731 drives the movable wheel 732 to rotate, the belt C733 will be synchronously driven, so that the guide frame 73 slides laterally on the surface of the connecting seat 72.

[0068] In this embodiment, the detection component includes a frame 5, which is mounted above the base 7 and fixedly connected to the base 7 by welding or bolting, and also includes a main camera 51 installed on the surface of the base 7. The main camera 51 is directly opposite to the center of the guide frame 73. Side cameras 511 are also installed on the inner wall of the frame 5 near both sides of the main camera 51. The main camera 51 and the side camera 511 are both industrial detection cameras, which are used to cooperate with each other to shoot the notebook screen and synthesize the detection image to improve the detection efficiency of problems such as bad pixels and plaques on the screen surface. A keyboard backlight camera 512 is installed on the inner wall of the frame 5. The keyboard backlight camera 512 is a visual camera used to detect the keyboard backlight of the tested notebook computer. It detects the keyboard backlight performance of the notebook computer through image recognition and light sensing. A shell surface camera A513 and a shell surface camera B514 are also installed on the top of the frame 5. They are used to detect the C shell surface and A shell surface of the notebook computer respectively. The shell surface camera A513 and the shell surface camera B514 are both industrial cameras. They detect the integrity of the shell surface by photographing the C shell surface and A shell surface of the notebook computer and performing image analysis.

[0069] Furthermore, it also includes a transverse plate 6 slidably connected to the top of the frame 5, the inner wall of the frame 5 is fixedly connected to a motor E61, and a side of the inner wall of the frame 5 close to the output end of the motor E61 is rotatably connected to a plurality of rollers, and the surfaces of the plurality of rollers are transmission-connected to belts A611, one side of the transverse plate 6 is fixedly connected to the belt A611, and the output shaft of the motor E61 is axially fixedly connected to one of the rollers. When the motor E61 outputs, the roller is driven to rotate, and then the belt A611 is transmitted, so that the transverse plate 6 moves laterally on the top of the frame 5 to adjust the lateral position of the transverse plate 6, and a movable frame 62 is slidably connected to the surface of the transverse plate 6 up and down, and two mark point plates 623 for providing positioning for the shell surface camera B514 are provided on the side of the movable frame 62 close to the shell surface camera B514, and a plurality of optical positioning points are provided on the surface of the mark point plate 623, and the positions and spacings of the plurality of optical positioning points are adjusted according to notebooks of different sizes. The movable frame 62 is fixedly connected to the inner wall of the movable frame 62 with a motor F621, and the surface of the horizontal plate 6 is threadedly connected with an adjusting screw 622. Both ends of the adjusting screw 622 are rotatably connected to the movable frame 62. The output end of the motor F621 is connected to the upper end of the adjusting screw 622 through a synchronous belt. The synchronous belt is respectively connected to the output shaft of the motor F621 and the upper end of the adjusting screw 622. When the motor F621 outputs, the adjusting screw 622 is driven to rotate, and then the adjusting screw 622 is moved up and down on the surface of the horizontal plate 6, so that the movable frame 62 is adjusted up and down in height to determine the working position of the Mark point plate 623. At the same time, after the movable frame 62 moves upward, it is also convenient for the notebook below to be pushed to the bottom of the shell camera A513 and the shell camera B514.

[0070] Specifically, through the output of motor E61, the horizontal plate 6 moves horizontally on the top of the frame 5 to adjust the horizontal position of the Mark point plate 623, and through the output of motor F621, the movable frame 62 moves up and down on the surface of the horizontal plate 6 to adjust the vertical position of the Mark point plate 623, so as to adapt to the different positions of the Mark point plate 623 according to the size of the notebook to be detected, and dynamically adjust the detection point of the shell camera B514.

[0071] Furthermore, the notebook is first inspected by the main camera 51, the side camera 511 and the keyboard backlight camera 512, and then the notebook is moved to the bottom of the shell camera A513 by the guide frame 73. It should be noted that the illumination direction of the shell camera A513 is vertically downward, while the illumination direction of the shell camera B514 is obliquely downward. When inspecting the C shell and A shell of the notebook, the opening angle of the notebook should be greater than 90 degrees, so that the shell camera A513 can inspect the C shell surface, that is, the keyboard surface of the notebook. Then, the positioning component is used to push the A shell surface of the notebook to rotate to a direction perpendicular to the illumination angle of the shell camera B514. During this period, the output of the motor F621 is synchronized to move the movable frame 62 downward, driving the Mark point plate 623 to move downward to the working position of the shell camera B514, so that the shell camera B514 can perform point positioning, thereby facilitating the inspection of the A shell of the notebook.
