Description

Technical Field

[0001] This invention relates to the field of screen testing technology, and in particular to a screen aging testing platform. Background Technology

[0002] The aging test of the screen is a part of the production process. It eliminates the bright and dark spot defects caused by the TFT circuit by inputting specific timing sequences to the TFT (Thin-Film Transistor), screens out the weaknesses in the conduction of the front-end electrical connection, reduces the failure rate of the LED (Light Emitting Diode) in the early stage of product use, and improves the display quality and stability of the screen.

[0003] In existing technology, the testing platform is equipped with a crimp connector, which is used to crimp the connecting end of the screen and conduct electricity through it. However, the alignment accuracy between the crimp connector and the screen is high, requiring a CCD camera for alignment to ensure this accuracy. The testing platform has two crimping methods: front crimping and back crimping. In front crimping, the CCD camera is positioned below the testing platform; in back crimping, the CCD camera is positioned above. To make the testing platform compatible with both front and back crimping functions, CCD cameras need to be placed at both the top and bottom of the platform, resulting in a complex structure. Furthermore, the lower CCD camera is prone to interference with the robotic arm. Summary of the Invention

[0004] The purpose of this invention is to propose a test platform for screen aging that simplifies the structure, utilizes a vision alignment component to meet the requirements of front and back pressing, improves alignment accuracy, and effectively avoids the problem of interference between the vision alignment component below and the robotic arm.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A screen aging test platform, comprising:

[0007] A pressing mechanism includes a support plate, a reflective component, and a pressing assembly. The support plate is used to place the screen to be tested. The reflective component is disposed on the support plate. The pressing assembly is located on the support plate. The pressing assembly includes a pressing connector and a power supply connection terminal. The power supply connection terminal is disposed below the pressing connector. The pressing connector is used to press the power supply connection terminal to the connection terminal of the screen to make the screen conductive.

[0008] A visual alignment component is disposed above the reflective component, and the visual alignment component can align the connection end of the screen with the power supply connection end through the reflective component.

[0009] As an optional solution for the test platform for the aforementioned screen aging, the support plate is provided with a reflective groove, and the reflective component is disposed within the reflective groove.

[0010] As an optional solution for the test platform for the aforementioned screen aging, the reflective component includes an incident mirror and an exit mirror arranged at an angle, and the visual alignment component can observe the crimp joint through the incident mirror and the exit mirror to determine the position of the crimp joint.

[0011] As an optional solution for the test platform for the aging of the screen, the opposite side walls of the reflective groove are inclined, the incident mirror is disposed on one of the opposite side walls of the reflective groove, and the exiting mirror is disposed on the other side wall of the opposite side walls of the reflective groove.

[0012] As an optional solution for the test platform for the aforementioned screen aging, the reflective component also includes optical glass, which is disposed within the reflective groove and located between the incident mirror and the exit mirror.

[0013] As an optional solution for the above-mentioned screen aging test platform, the reflective component also includes a light-shielding component. The light-shielding component is disposed on the upper surface of the optical glass. The light-shielding component divides the groove of the reflective slot into a light inlet and a light outlet. In the vertical direction, the projection of the incident mirror on the upper surface of the light-shielding component is located in the light inlet, and the projection of the exiting mirror on the upper surface of the light-shielding component is located in the light outlet.

[0014] As an optional solution for the test platform for the aforementioned screen aging, the incident mirror surface and the exit mirror surface are perpendicular to each other.

[0015] As an optional solution for the above-mentioned screen aging test platform, the pressing assembly further includes a fixed base, an elastic element, and a rotating element. The pressing head is movably disposed on the fixed base in a vertical direction, and the rotating element is rotatably disposed on the fixed base. One end of the rotating element is movably connected to the pressing head. The two ends of the elastic element abut against the fixed base and the rotating element respectively so that the rotating element presses the pressing head onto the connection end of the screen.

[0016] As an optional solution for the aforementioned screen aging test platform, the test platform also includes a base plate, on which two sets of pressing mechanisms are slidably arranged. The distance between the two sets of pressing mechanisms is adjustable. Each set of pressing mechanisms is provided with a set of visual alignment components. Terminals are provided at both opposite ends of the screen. The pressing head of one set of pressing mechanisms presses the corresponding power supply connection end to the terminal at one end of the screen, and the pressing head of the other set of pressing mechanisms presses the corresponding power supply connection end to the terminal at the other end of the screen.

[0017] As an optional solution for the above-mentioned screen aging test platform, the base plate is provided with a slide rail, the support plate is slidably disposed on the slide rail, and the pressing mechanism further includes a locking member, which is configured to lock the relative position between the support plate and the base plate.

[0018] The beneficial effects of this invention are:

[0019] This invention provides a testing platform for screen aging. In this testing platform, the support plate of the pressing mechanism supports the screen to be tested, and the pressing joint of the pressing component presses the connection end of the screen to enable conductivity. To ensure the alignment accuracy between the power supply connection end and the screen connection end, a reflective component is provided on the support plate. When back-side pressing is required, the visual alignment component can observe the position of the power supply connection end through the reflective component; when front-side pressing is required, the visual alignment component can directly observe the position of the power supply connection end. Since the screen connection end is a transparent structure, the visual alignment component can directly collect position information of the screen connection end, thereby completing the alignment of the power supply connection end and the screen connection end. Furthermore, the position of the visual alignment component remains unchanged, ensuring alignment accuracy.

[0020] This testing platform simplifies the structure, utilizes a single vision alignment device to meet the requirements of both front and back pressing, improves alignment accuracy, and effectively avoids interference between the vision alignment device below and the robotic arm.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Aging testing of the screen is part of the production process. It eliminates bright and dark spot defects caused by the TFT circuit by adjusting the specific timing of the TFT input, screens out weaknesses in the conduction of the front-end electrical connection, reduces the failure rate of LEDs in the early stage of product use, and improves the display quality and stability of the screen.

[0037] like Figures 1-3 As shown, this embodiment provides a test platform for screen aging. The test platform includes a pressing mechanism 1 and a visual alignment component 2. The pressing mechanism 1 includes a support plate 11, a reflective component 12, and a pressing component 13. The support plate 11 is used to support the screen to be tested. The reflective component 12 is disposed on the support plate 11. The pressing component 13 is located on the support plate 11. The pressing component 13 includes a pressing connector 131 and a power supply connection end. The power supply connection end is disposed below the pressing connector 131. The pressing connector 131 is used to press the power supply connection end to the connection end of the screen to make the screen conductive. The visual alignment component 2 is disposed above the reflective component 12. The visual alignment component 2 can observe the position of the connection end of the screen and can observe the position of the power supply connection end through the reflective component 12.

[0038] In this test platform, the support plate 11 of the pressing mechanism 1 is used to support the screen to be tested, and the pressing joint 131 of the pressing component 13 is used to press the connection end of the screen to make the screen conductive. In order to ensure the alignment accuracy between the power supply connection end and the connection end of the screen, a reflective component 12 is provided on the support plate 11.

[0039] It is worth noting that the screen body includes a screen body and a connecting plate disposed at the end of the screen body. The connecting end of the screen body is disposed at the end of the connecting plate away from the screen body and below the pressure joint 131. The screen body is disposed on the support plate 11 and does not cover the reflective component 12, while the connecting plate covers part of the reflective component 12. In this embodiment, the connecting plate of the screen body is a transparent structure, preferably an FPC board (Flexible Printed Circuit), so that the visual alignment member 2 can collect position information of the connecting end of the screen body through the connecting plate covering the reflective component 12.

[0040] If the connection end of the screen is located on the front of the screen, front crimping is required, that is, the power supply connection end is located above the connection end of the screen. At this time, the power supply connection end will be blocked by the crimp connector 131, and the visual alignment component 2 needs to observe the position of the power supply connection end through the reflective component 12. If the connection end of the screen is located on the back of the screen, back crimping is required, that is, the power supply connection end is located below the screen. At this time, the power supply connection end is not blocked by the crimp connector 131, and the visual alignment component 2 can directly observe the position of the power supply connection end.

[0041] This completes the alignment of the power supply connection end with the screen connection end, while the position of the visual alignment component 2 remains unchanged, and the relative positions of the reflective component 12, the pressure connector 131, and the power supply connection end in the horizontal direction remain unchanged, thus ensuring alignment accuracy.

[0042] In existing technologies, to enable a testing platform to support both front and back pressing functions, visual alignment components need to be installed at both the top and bottom of the platform. For front pressing, the lower component is used for alignment, while for back pressing, the upper component is used. This structure is complex, and the lower component is prone to interference with the robotic arm handling the screen. In this embodiment, the testing platform simplifies its structure, utilizing a single visual alignment component 2 to meet both front and back pressing requirements, improving alignment accuracy and effectively avoiding interference between the lower component 2 and the robotic arm.

[0043] The visual inspection component can be a camera or a CCD camera. Regarding the power supply connection, for front-side crimping, the power supply connection can be located at the bottom of the crimp connector 131, or an FPC board can be placed between the crimp connector 131 and the support plate 11, using the crimp connector 131 to crimp the power supply connection of the FPC board to the connection of the screen body. For back-side crimping, an FPC board is placed between the crimp connector 131 and the support plate 11, using the crimp connector 131 to crimp the power supply connection of the FPC board to the connection of the screen body. In this embodiment, the power supply connection is a gold finger. To facilitate alignment, alignment information is provided around the gold finger, such as alignment terminals, or other features are used for alignment.

[0044] In this embodiment, the alignment process is as follows:

[0045] If front-side bonding is performed, the alignment information of the gold fingers is directly observed using a CCD camera, and the coordinate position is recorded. If back-side bonding is performed, the alignment information of the gold fingers is observed using a CCD camera through the reflective component 12, and the coordinate position is recorded. Then, a robotic arm is used to move the screen body above the support plate 11, and the position of the connecting end of the screen body is recorded using a CCD camera. The coordinate difference between the position of the connecting end of the screen body and the position of the gold fingers is analyzed, and the robotic arm is controlled to move to compensate for the coordinate difference, thus ensuring that the connecting end of the screen body and the gold fingers are aligned.

[0046] Since the crimp connector 131 will exert a certain pressure on the connection end of the screen, and the reflective component 12 is located below the crimp connector 131, in order to prevent the reflective component 12 from being damaged by the crimp connector 131 or from interfering with the screen, the support plate 11 is provided with a reflective groove, and the reflective component 12 is disposed in the reflective groove.

[0047] Furthermore, the top surface of the reflective component 12 is on the same plane as the top surface of the support plate 11 to ensure that the screen can be stably set on the support plate 11.

[0048] like Figure 3 As shown, the reflective assembly 12 includes an incident mirror 121 and an exit mirror 122 arranged at an angle. The visual alignment member 2 can observe the crimp connector 131 through the incident mirror 121 and the exit mirror 122 to determine the position of the crimp connector 131. It is understood that the incident mirror 121 and the exit mirror 122 arranged at an angle can change the direction of light propagation. Therefore, the arrangement position of the visual alignment member 2 can be selected according to the actual situation, and then the incident mirror 121 and the exit mirror 122 can be used to enable the visual alignment member 2 to directly observe the gold finger.

[0049] In this embodiment, in order to ensure the stability of the incident mirror 121 and the exit mirror 122, the opposite side walls of the reflective groove are inclined. The incident mirror 121 is disposed on one of the opposite side walls of the reflective groove, and the exit mirror 122 is disposed on the other side wall of the opposite side walls of the reflective groove.

[0050] Furthermore, the incident mirror 121 and the exit mirror 122 are perpendicular to each other. This structure allows the propagation directions of the exit light and the incident light to be parallel and opposite. In other words, the CCD camera can be positioned directly above the exit mirror 122, while the incident mirror 121 is positioned directly below the gold fingers, which facilitates both observation and recording of the gold finger position.

[0051] In this embodiment, the reflective assembly 12 further includes optical glass 123, which is disposed within the reflective groove and located between the incident mirror surface 121 and the exit mirror surface 122. The optical glass 123 has a uniform internal refractive index, which reduces optical distortion, ensures uniform light transmission, improves image clarity, and thus enhances alignment accuracy.

[0052] Furthermore, the cross-section of the optical glass 123 is an isosceles trapezoid, and the incident mirror 121 and the exit mirror 122 are respectively attached to the two hypotenuses of the isosceles trapezoid. The propagation path of the light emitted by the gold finger is optical glass 123 → incident mirror 121 → optical glass 123 → exit mirror 122 → optical glass 123. Vertically from top to bottom, the width of the reflective groove gradually decreases. To accommodate the optical glass 123, the inclination angle of the inner wall of the reflective groove is equal to the inclination angle of the hypotenuse of the optical glass 123; that is, the optical glass 123 is an inverted trapezoid.

[0053] In this embodiment, the upward-facing surface of the optical glass 123 is described as the upper surface, and the downward-facing surface of the optical glass 123 is described as the lower surface. The reflective assembly 12 also includes a light-shielding member 124, which is disposed on the upper surface of the optical glass 123. The light-shielding member 124 divides the opening of the reflective groove into a light inlet and a light outlet. In the vertical direction, the projection of the incident mirror 121 onto the upper surface of the light-shielding member 124 is located within the light inlet, and the projection of the exiting mirror 122 onto the upper surface of the light-shielding member 124 is located within the light outlet.

[0054] The light-shielding element 124 can reduce the impact of other light entering the optical glass 123 on imaging, and also minimize other images in the CCD camera's image frame, thereby reducing the workload of image analysis and improving efficiency.

[0055] Specifically, the incident mirror 121 and the exit mirror 122 cover the inclined surface of the optical glass 123. In the vertical direction, the projection of the light-shielding member 124, located on the upper surface of the optical glass 123, onto the upper surface of the optical glass 123 coincides with the projection of the lower surface of the optical glass 123 onto the upper surface of the optical glass 123. Therefore, in the vertical direction, the light-shielding member 124 blocks the gap between the incident mirror 121 and the exit mirror 122.

[0056] Furthermore, to reduce the weight of the testing platform, the thickness of the support plate 11 needs to be strictly controlled. Therefore, the reflective groove is a vertical through groove, and the lower surface of the optical glass 123 is on the same plane as the bottom surface of the support plate 11. At this time, the lower surface of the optical glass 123 is transparent. In order to avoid affecting the image acquisition of the CCD camera, a light-shielding element 124 is also attached to the lower surface of the optical glass 123.

[0057] like Figures 2-4 As shown, the pressing assembly 13 also includes a fixed base 132, an elastic element 133, and a rotating element 134. The pressing joint 131 is movably disposed on the fixed base 132 in the vertical direction, and the rotating element 134 is rotatably disposed on the fixed base 132. One end of the rotating element 134 is floatingly connected to the pressing joint 131. The two ends of the elastic element 133 abut against the fixed base 132 and the rotating element 134 respectively so that the rotating element 134 presses the pressing joint 131 onto the connecting end of the screen body.

[0058] When the rotating part 134 is pressed away from the end of the crimping connector 131, the rotating part 134 drives the crimping connector 131 to move upward and compress the elastic element 133. At this time, the screen can be placed on the support plate 11 and the terminal can be placed between the crimping connector 131 and the support plate 11. Then the rotating part 134 is released, and the crimping connector 131 will press the gold finger onto the connection end of the screen under the drive of the elastic element 133.

[0059] In this embodiment, the fixed base 132 includes two columns 1322 spaced apart and a fixed top cover 1323 connected to the two columns 1322. The rotating member 134 has a rotating shaft 1342 at both ends. The two rotating shafts 1342 are rotatably connected to the corresponding columns 1322. The pressure joint 131 is located between the two columns 1322, and the elastic member 133 is located between the pressure joint 131 and the fixed top cover 1323.

[0060] To ensure the accuracy of the crimp connector 131 during movement, a groove 1321 is provided on the inner side of the column 1322, and a slider 1311 is provided on the crimp connector 131, which is slidably disposed in the groove 1321.

[0061] It is understandable that, during the rotation of the rotating component 134, its end moves not only vertically but also horizontally. For example... Figures 3-6As shown, to prevent jamming, the crimp connector 131 is provided with a horizontal drive groove 1312, and one end of the rotating member 134 is provided with a slide rod 1341, which is slidably disposed within the drive groove 1312. The drive groove 1312 provides a degree of freedom for the relative movement between the slide rod 1341 and the crimp connector 131 in the horizontal direction. Therefore, as the rotating member 134 rotates, the crimp connector 131 can move in the vertical direction.

[0062] In existing technologies, the test platform and the screen body are in one-to-one correspondence. That is to say, different screen bodies of different sizes require different test platforms for aging tests, resulting in poor versatility of the test platform and many problems such as high cost, cumbersome switching, low uptime, and complex maintenance.

[0063] like Figure 1 As shown, to solve the above problems, the test platform also includes a base plate 3. Two sets of pressing mechanisms 1 are slidably arranged on the base plate 3. The distance between the two sets of pressing mechanisms 1 is adjustable. Each set of pressing mechanisms 1 is provided with a set of visual alignment components 2. Terminals are provided at both ends of the screen. The pressing connector 131 of one set of pressing mechanisms 1 presses the corresponding power supply connection terminal to the terminal at one end of the screen, and the pressing connector 131 of the other set of pressing mechanisms 1 presses the corresponding power supply connection terminal to the terminal at the other end of the screen.

[0064] Based on the actual size of the screen to be tested, adjust the distance between the two pressing mechanisms 1 so that the screen can be set on the support plates 11 of the two pressing mechanisms 1, with the terminal at one end of the screen located below the crimping joint 131 of one pressing mechanism 1, and the terminal at the other end of the screen located below the crimping joint 131 of the other pressing mechanism 1. Replace the gold fingers of the connection end suitable for the screen and align them to ensure the alignment accuracy between the terminals at both ends of the screen and the corresponding gold fingers, thus completing the aging test of the screen.

[0065] Furthermore, a slide rail 31 is provided on the base plate 3, and the support plate 11 is slidably disposed on the slide rail 31. The pressing mechanism 1 also includes a locking element, which is configured to lock the relative position between the support plate 11 and the base plate 3. The slide rail 31 can ensure the positional accuracy between the two pressing mechanisms 1, so that the distance between the two pressing mechanisms 1 can only be adjusted, and no displacement will occur in the direction perpendicular to the relative movement of the two pressing mechanisms 1. The locking element can lock the position of the pressing mechanism 1 on the base plate 3 to prevent the pressing mechanism 1 from moving and affecting the alignment accuracy.

[0066] To further improve testing efficiency, multiple sets of pressing mechanisms 1 are set on the base plate 3, with two pressing mechanisms 1 that can adjust the spacing as a group, so as to perform aging tests on multiple screens at the same time.

[0067] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
