Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of panel detection, and in particular to a loading mechanism for carrying a display module. BACKGROUND

[0002] At present, display screens have been widely applied to various scenes in people's life and have become an indispensable part of people's life. With the development of science and technology, virtual reality (VR) and augmented reality head-mounted devices have applied many new technologies, which have gradually attracted people's attention to near-eye display screens (NED).

[0003] In related technologies, in the production process of a display module of a display screen, an AOI technology is used to perform optical automatic detection (AOI) on a display picture of the display module to ensure the quality of the display module. Before optical detection of the display module by an optical automatic detection device, a multi-axis moving module is used to automatically move the optical module from a feeding and discharging station to a detection station, and the position and posture of the display module need to be automatically adjusted.

[0004] However, in order to have greater flexibility, most of the multi-axis moving modules of the optical detection devices on the market are usually stacked in sequence in multiple position adjustment mechanisms, which results in an excessively high overall height. During optical detection, the overall structure of the multi-axis moving module usually shakes due to the movement of the multi-axis moving module, which causes the problem of unstable structure, and further affects the accuracy of the measured product and the production efficiency. SUMMARY

[0023] The beneficial effects of the technical solution provided in this application include:

[0024] This application provides a platform mechanism for transporting display modules. The platform mechanism includes a base, a position adjustment mechanism, a product platform, and a pressure point screen module. The position adjustment mechanism is located on the base, and the product platform is located on the position adjustment mechanism to place and position the product under test. The pressure point screen module is used to press and illuminate the product under test on the product platform. The position adjustment mechanism includes at least a horizontal adjustment mechanism and a vertical adjustment mechanism that drive the product platform to move in the horizontal and vertical directions. The vertical adjustment mechanism is located on the side of the horizontal adjustment mechanism and connected to the output shaft of the horizontal adjustment mechanism.

[0025] Therefore, the platform mechanism of this application is equipped with a position adjustment mechanism on the base to adjust the position of the product platform, thereby automatically transporting the product under test located on the product platform to a set workstation for testing. The pressing point screen module is used to automatically press and illuminate the product under test located on the product platform, realizing the automated operation of transporting and illuminating the product under test. The vertical adjustment mechanism of the position adjustment mechanism is set on the side of the horizontal adjustment mechanism and connected to the output shaft of the horizontal adjustment mechanism, thereby lowering the center of gravity of the position adjustment mechanism and the product platform. This improves the structural stability of the platform mechanism, enhances the accuracy of optical inspection, and increases production efficiency when the product under test on the product platform is subjected to optical inspection.

[0026] The vertical adjustment mechanism of this application includes a lifting mechanism that drives the product platform to move vertically, and a drive mechanism that drives the lifting mechanism to move up and down. The drive shaft of the drive mechanism moves perpendicular to the movement direction of the lifting mechanism. The vertical adjustment mechanism of this application consists of a lifting mechanism and a drive mechanism. The lifting mechanism moves vertically, and the drive shaft of the drive mechanism moves perpendicular to the movement direction of the lifting mechanism, thereby reducing the overall height of the vertical adjustment mechanism. This further reduces the center of gravity height of the position adjustment mechanism and the product platform, thereby improving the structural stability of the platform mechanism when the product under test on the product platform is subjected to optical inspection.

[0027] The horizontal adjustment mechanism of this application includes a first horizontal adjustment mechanism that drives the product platform to move along a first horizontal direction and a second horizontal adjustment mechanism that drives the product platform to move along a second horizontal direction. This horizontal adjustment mechanism utilizes the first and second horizontal adjustment mechanisms to drive the vertical adjustment mechanism and the product platform to move along the first and second horizontal directions respectively, thereby improving the flexibility and coverage of handling the product platform and the product under test.

[0028] The first and second leveling mechanisms of this application are perpendicularly connected to each other, with the second leveling mechanism connected to the top of or to one side of the first leveling mechanism. The first and second leveling mechanisms can be connected perpendicularly to each other, or the second leveling mechanism can be connected to one side of the first leveling mechanism. When the second leveling mechanism is connected to one side of the first leveling mechanism, the heights of the first and second leveling mechanisms are equal, further reducing the center of gravity height of the position adjustment mechanism and the product platform.

[0029] The vertical adjustment mechanism of this application is located on one side of the second horizontal adjustment mechanism, and the length direction of the vertical adjustment mechanism is parallel to the length direction of the second horizontal adjustment mechanism. This arrangement reduces the height difference between the vertical and horizontal adjustment mechanisms and makes their length directions more parallel, resulting in a smaller space occupied by both mechanisms and a more compact structure.

[0030] The pressure-sensitive touchscreen module of this application includes a test circuit board for illuminating the product under test (DUT). One end of the test circuit board is equipped with a conductive component that presses and connects to the DUT. A pressing mechanism on the product platform drives the test circuit board to press the conductive component onto the DUT, and a translation mechanism connects to the pressing mechanism and drives the test circuit board to approach or move away from the DUT. The test circuit board illuminates the DUT. The pressing mechanism and translation mechanism on the product platform drive the test circuit board to move vertically and horizontally. When the pressing mechanism moves vertically, it connects or disconnects the test circuit board from the DUT. When the translation mechanism moves horizontally or backward, it moves the test circuit board into or out of the top of the DUT, thus automatically completing the illuminating and disconnecting actions of the DUT.

[0031] The pressing mechanism of this application includes a slide block slidably connected to a product platform, and a lifting cylinder connected to the slide block to drive the test circuit board to move up and down; the translation mechanism includes a push cylinder fixedly connected to the product platform, and the telescopic arm of the push cylinder is connected to the slide block. The lifting cylinder drives the test circuit board to move up and down, thereby enabling the conductive components of the test circuit board to be connected or disconnected from the product under test. The push cylinder, by driving the slide block to move left and right or back and forth, is used to move the test circuit board into or out of the top of the product under test.

[0032] This application includes a temperature control module connected to the product carrier that contacts the product under test. The top of the temperature control module has a vacuum suction cup for adsorbing the product under test. The product carrier also has a through-beam sensor for detecting the product under test. The temperature control module contacts the product under test, thereby precisely controlling the detection temperature of the product during optical inspection. This allows for the measurement of the optical parameters of the product under test under different or constant temperature environments, leading to an accurate and objective evaluation of the imaging effect. The temperature control module also integrates a vacuum suction cup that secures the product under test to the product carrier, preventing displacement during movement or inspection. The through-beam sensor detects whether the product under test is placed on the product carrier, improving the reliability of the inspection.

[0033] The other end of the test circuit board in this application is provided with a connector socket for connecting a signal generator. The signal generator is fixed on the base and connects to the product under test (DUT) through the test circuit board. The other end of the test circuit board is connected to the signal generator via the connector socket. The signal generator is used to transmit test electrical signals to the test circuit board. After the test circuit board and the DUT are crimped together, the DUT lights up. The signal generator is fixed to the base and does not move with the position adjustment mechanism, reducing the load on the position adjustment mechanism.

[0034] The position adjustment mechanism of this application further includes a first rotating module, a second rotating module, and a third rotating module fixed to the vertical adjustment mechanism and connected in sequence; the product stage is fixed on the top of the third rotating module. The position adjustment mechanism can realize linear movement of the product stage and the product under test along the X-axis, Y-axis, and Z-axis, and can rotate around the X-axis, Y-axis, and Z-axis, thereby flexibly and accurately adjusting the position and orientation of the product stage and the product under test, so that the product stage and the product under test can be optically inspected in a set position and orientation.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides a platform mechanism for transporting display modules, which can solve the problem in related technologies where the overall height of multi-axis moving modules is too high, causing the overall structure to shake and become unstable during movement.

[0046] SeeFigures 1 to 3 As shown, this application embodiment provides a platform mechanism for transporting display modules, including: a base 40, a position adjustment mechanism 20, a product platform 10, and a pressing screen module. The base 40 is provided with the position adjustment mechanism 20, and the position adjustment mechanism 20 is provided with the product platform 10 for placing and positioning the product under test 12. The product under test 12 is positioned on the product platform 10 by a product carrier 11. The pressing screen module is used to press and light up the product under test 12 on the product platform 10. The product under test 12 is preferably a display module.

[0047] The position adjustment mechanism 20 includes at least a horizontal adjustment mechanism and a vertical adjustment mechanism 22 that drive the product stage 10 to move horizontally and vertically. The vertical adjustment mechanism 22 is disposed on the side of the horizontal adjustment mechanism and connected to the output shaft of the horizontal adjustment mechanism. The horizontal adjustment mechanism is used to drive the product stage 10 and the product under test 12 to move horizontally, and the vertical adjustment mechanism 22 is used to drive the product stage 10 and the product under test 12 to move vertically. The horizontal adjustment mechanism and the vertical adjustment mechanism 22 cooperate to transport the product stage 10 and the product under test 12 to the set work position.

[0048] The platform mechanism of this application has a position adjustment mechanism 20 on the base 40 for adjusting the position of the product platform 10, thereby automatically transporting the product under test 12 located on the product platform 10 to a set workstation for testing. The pressing point screen module is used to automatically press and light up the product under test 12 located on the product platform 10, realizing the automated operation of transporting and lighting up the product under test.

[0049] The vertical adjustment mechanism 22 of the position adjustment mechanism 20 is located on the side of the horizontal adjustment mechanism and connected to the output shaft of the horizontal adjustment mechanism. This lowers the center of gravity of the position adjustment mechanism 20 and the product stage 10, thereby improving the structural stability of the stage mechanism, the accuracy of optical inspection, and the production efficiency when the product 12 under test on the product stage 10 is subjected to optical inspection.

[0050] In some alternative embodiments, see Figures 1 to 3 As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The vertical adjustment mechanism 22 of the platform mechanism includes a lifting mechanism that drives the product platform 10 to move vertically, and a drive mechanism that drives the lifting mechanism to move up and down. The drive shaft of the drive mechanism moves in a direction perpendicular to the movement direction of the lifting mechanism. The lifting mechanism is preferably, but not limited to, a wedge-shaped slider, and the drive mechanism is preferably, but not limited to, a push screw that drives the wedge-shaped slider to move up and down.

[0051] The vertical adjustment mechanism 22 in this embodiment consists of a lifting mechanism and a driving mechanism. The lifting mechanism moves vertically, and the driving shaft of the driving mechanism moves perpendicular to the direction of the lifting mechanism, thereby reducing the overall height of the vertical adjustment mechanism 22. This further reduces the center of gravity height of the position adjustment mechanism 20 and the product stage 10, thereby improving the structural stability of the stage mechanism when the product under test 12 on the product stage 10 is subjected to optical inspection.

[0052] In some alternative embodiments, see Figures 1 to 3 As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The horizontal adjustment mechanism of the platform mechanism includes a first horizontal adjustment mechanism 23 that drives the product platform 10 to move along a first horizontal direction and a second horizontal adjustment mechanism 21 that drives the product platform 10 to move along a second horizontal direction. The first horizontal adjustment mechanism 23 and the second horizontal adjustment mechanism 21 are preferably, but not limited to, linear modules. The linear modules can be selected from lead screw linear modules, gear linear modules, or synchronous belt linear modules.

[0053] The horizontal adjustment mechanism in this embodiment utilizes a first horizontal adjustment mechanism 23 and a second horizontal adjustment mechanism 21 to drive the vertical adjustment mechanism 22 and the product platform 10 to move along the first horizontal direction and the second horizontal direction, respectively, thereby improving the flexibility and coverage of the transport product platform and the product under test. The first horizontal direction is the X-axis direction, the second horizontal direction is the Y-axis direction, and the vertical direction is the Z-axis direction.

[0054] In some alternative embodiments, see Figures 1 to 3 As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The first horizontal adjustment mechanism 23 and the second horizontal adjustment mechanism 21 of the platform mechanism are vertically connected to each other. The second horizontal adjustment mechanism 21 is connected to the top of the first horizontal adjustment mechanism 23 or to one side of the first horizontal adjustment mechanism 23.

[0055] In this embodiment of the application, the first horizontal adjustment mechanism 23 and the second horizontal adjustment mechanism 21 can be connected perpendicularly to each other, or the second horizontal adjustment mechanism 21 can be connected to one side of the first horizontal adjustment mechanism 23. When the second horizontal adjustment mechanism 21 is connected to one side of the first horizontal adjustment mechanism 23, the heights of the first horizontal adjustment mechanism 23 and the second horizontal adjustment mechanism 21 are the same, further reducing the center of gravity height of the position adjustment mechanism 20 and the product platform 10.

[0056] A linear guide rail 24, parallel to and spaced apart from the first horizontal adjustment mechanism 23, is also provided on the top of the base 40. The second horizontal adjustment mechanism 21 is slidably connected to the linear guide rail 24 via a slider. The linear guide rail 24 is used to cooperate with the first horizontal adjustment mechanism 23 to jointly slide and support the second horizontal adjustment mechanism 21, thereby enhancing the structural stability of the position adjustment mechanism 20.

[0057] In some alternative embodiments, see Figures 1 to 3 As shown, this application embodiment provides a platform mechanism for transporting display modules. The vertical adjustment mechanism 22 of the platform mechanism is located on one side of the second horizontal adjustment mechanism 21, and the length direction of the vertical adjustment mechanism 22 is parallel to the length direction of the second horizontal adjustment mechanism 21.

[0058] The vertical adjustment mechanism 22 of this embodiment is located on one side of the second horizontal adjustment mechanism 21, reducing the height difference between the vertical adjustment mechanism 22 and the second horizontal adjustment mechanism 21, and making the length direction of the vertical adjustment mechanism 22 parallel to the length direction of the second horizontal adjustment mechanism 21, so that the vertical adjustment mechanism 22 and the second horizontal adjustment mechanism 21 occupy less space and the structure is more compact.

[0059] In some alternative embodiments, see Figures 1 to 3 As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The platform mechanism includes a screen pressing module for illuminating the product under test 12, and one end of the test circuit board 13 is provided with a conductive component for pressing and connecting the product under test 12. The product platform 10 is provided with a pressing mechanism 14 for driving the test circuit board 13 to press the conductive component onto the product under test 12, and a translation mechanism 15 connected to the pressing mechanism 14 and driving the test circuit board 13 to approach or move away from the product under test 12.

[0060] In this embodiment, the test circuit board 13 is used to illuminate the product under test 12. The pressing mechanism 14 and the translation mechanism 15 on the product platform 10 are used to drive the test circuit board 13 to move vertically and horizontally. When the pressing mechanism 14 moves vertically, it is used to connect or disconnect the test circuit board 13 from the product under test 12. When the translation mechanism 15 moves left or right or back and forth, it is used to move the test circuit board 13 into or out of the top of the product under test 12, thereby automatically completing the lighting connection and disconnection actions of the product under test 12.

[0061] In some alternative embodiments, see Figures 1 to 3As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The pressing mechanism 14 of the platform mechanism includes a slide block slidably connected to the product platform 10, and a lifting cylinder connected to the slide block to drive the test circuit board 13 to move up and down. The translation mechanism includes a push cylinder fixedly connected to the product platform 10, and the telescopic arm of the push cylinder is connected to the slide block.

[0062] In this embodiment, the lifting cylinder drives the test circuit board 13 to move up and down, thereby enabling the conductive components of the test circuit board 13 to be connected or disconnected from the product under test 12. The pushing cylinder moves the slide left and right or back and forth to move the test circuit board 13 into or out of the top of the product under test 12.

[0063] In some alternative embodiments, see Figures 1 to 3 As shown, this application embodiment provides a platform mechanism for transporting display modules. The product platform 10 of the platform mechanism is connected to a temperature control module 18 that contacts the product 12 under test. The top of the temperature control module 18 is provided with a vacuum suction cup for vacuum adsorption of the product 12 under test. The product platform 10 is also provided with a through-beam sensor 19 for detecting the product 12 under test.

[0064] In this embodiment, the temperature control module 18 contacts the product under test 12, thereby precisely controlling the detection temperature of the product under test 12 during optical inspection. This allows for accurate and objective evaluation of the imaging effect of the product under test under different or constant temperature environments. The temperature control module 18 also integrates a vacuum suction cup for adsorbing the product under test 12, which fixes the product under test 12 onto the product carrier 11, preventing displacement during movement or inspection. A through-beam sensor 19 detects whether the product under test 12 is placed on the product stage 10, improving the reliability of the inspection.

[0065] In some alternative embodiments, see Figures 1 to 3 As shown, this application embodiment provides a platform mechanism for transporting display modules. The other end of the test circuit board 13 of the platform mechanism is provided with a connector socket 16 for connecting a signal generator 17. The signal generator 17 is fixed on the base 40 and is connected to the product under test 12 through the test circuit board 13.

[0066] In this embodiment, the other end of the test circuit board 13 is connected to the signal generator 17 via a connector socket 16. The signal generator 17 is used to transmit test electrical signals to the test circuit board 13. After the test circuit board 13 is crimped to the product under test 12, the product under test 12 is illuminated. The signal generator 17 is fixed to the base 40 and does not move with the position adjustment mechanism 20, thus reducing the load on the position adjustment mechanism 20.

[0067] In some alternative embodiments, see Figures 1 to 3 As shown, this application embodiment provides a platform mechanism for transporting display modules. The position adjustment mechanism 20 of the platform mechanism further includes a first rotating module 25, a second rotating module 26, and a third rotating module 27, which are fixed on the vertical adjustment mechanism 22 and connected in sequence. The first rotating module 25 rotates around the Y-axis, the second rotating module 26 rotates around the X-axis, and the third rotating module 27 rotates around the Z-axis. The product platform 10 is fixed on the top of the third rotating module 27.

[0068] The position adjustment mechanism 20 of this application embodiment can realize linear movement of the product stage 10 and the product under test 12 along the X-axis, Y-axis and Z-axis, and can rotate around the X-axis, Y-axis and Z-axis, thereby flexibly and accurately adjusting the position and orientation of the product stage 10 and the product under test 12, so that the product stage 10 and the product under test 12 can be optically inspected in the set position and orientation.

[0069] In some alternative embodiments: see Figure 2 and Figure 4 As shown in the figure, this application embodiment provides a platform mechanism for transporting display modules. The platform mechanism further includes a connecting bent plate 30 connecting the vertical adjustment mechanism 22 and the second horizontal adjustment mechanism 21. The connecting bent plate 30 includes an upper mounting plate 31 connecting the top of the second horizontal adjustment mechanism 21 and a lower mounting plate 33 connecting the bottom of the vertical adjustment mechanism 22. The lower mounting plate 33 is lower than the upper mounting plate 31, and a vertical connecting plate 32 connects the upper mounting plate 31 and the lower mounting plate 33.

[0070] The connecting plate 30 in this embodiment consists of an upper mounting plate 31, a vertical connecting plate 32, and a lower mounting plate 33 connected to each other, forming a "Z"-shaped structure. The upper mounting plate 31 is used to connect the slider of the second horizontal adjustment mechanism 21, and the lower mounting plate 33 is used to connect the base of the vertical adjustment mechanism. The vertical connecting plate 32 is used to lower the lower mounting plate 33 below the upper mounting plate 31, thereby lowering the overall height of the vertical adjustment mechanism 22 below the second horizontal adjustment mechanism 21, thus reducing the height of the vertical adjustment mechanism 22 and the product platform 10.

[0071] In some alternative embodiments: see Figure 1 As shown, this application embodiment provides a platform mechanism for transporting display modules. The base 40 of the platform mechanism has a pneumatic control module and an electrical control module connected to a position adjustment mechanism 20 and a product platform 10 via a cable chain at its bottom. A rectangular through hole 41 extending along the length direction of the first horizontal adjustment mechanism 23 is provided on the base 40. The pipeline in the cable chain passes through the rectangular through hole 41 and connects to the position adjustment mechanism 20 and the product platform 10.

[0072] This embodiment of the application provides a rectangular through-hole 41 extending vertically through the base 40, which facilitates the placement of the cable chain, pneumatic control module, and electrical control module below the base 40. The pipelines connecting the position adjustment mechanism 20 and the product platform 10 pass through the rectangular through-hole 41 and connect to the pneumatic control module and electrical control module. This saves space on the top of the base 40, allowing other testing equipment to be arranged on top of the base 40, thus improving space utilization.
