Description

Technical Field

[0001] The utility model relates to the technical field of display panel detection, in particular to a vacuum adjustment and alignment tool for a display panel. Background Art

[0002] When testing the OLED liquid crystal display panel, the OLED liquid crystal display panel is grabbed by a robotic arm and moved above the device camera. The device vision software finds the mark on the electrode area on the OLED liquid crystal display panel and compares it with the mark on the device fixed soft board, so as to perform crimping with the soft board. After the device fixed soft board is powered on, the OLED liquid crystal display panel is powered on and lit up and the color change test is performed.

[0003] The OLED liquid crystal display panel is made of soft material, and the robotic arm deforms and bends when grasping it, causing it to move above the camera. The visual window cannot accurately find the markings on the electrode area on the OLED liquid crystal display panel. The existing robotic arm mainly uses multiple spaced vacuum nozzles to perform negative pressure grasping on the display panel, but due to its softness, deformation occurs in the area to be tested, resulting in test failure.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-Figure 4 As shown, in the embodiment of the utility model, a display panel vacuum adjustment and alignment tool is proposed, which is applied to the equipment for grabbing, moving and detecting the flexible display panel. The tool mainly uses the vacuum negative pressure adsorption force to realize the grabbing and moving of the display panel. Specifically, it includes a rotating mounting table 1 and a slide 2 fixed on the rotating mounting table 1, a slider 3 is slidably mounted on the slide 2, a vacuum adsorption module 4 is mounted on the slider 3, and a plurality of vacuum pinholes 5 for adsorption are provided on the vacuum adsorption module 4. The vacuum pinholes 5 are distributed in an array and evenly arranged to achieve the effect of uniform adsorption. The slider 3 can slide relative to the slide 2, and when the vacuum adsorption module 4 contacts the detection area of ​​the display panel, it is buffered and ensures that the negative pressure generated by the vacuum pinhole 5 smoothly grabs the area. Since the side of the vacuum adsorption module 4 that contacts the display panel is a plane, it can ensure that the display panel in the detection area remains flat, and since the contact area of ​​the vacuum adsorption module 4 is large, it can prevent the display panel from being scratched.

[0027] The overall tooling can be installed with the rotating mounting table 1 to achieve angle adjustment. Meanwhile, a connecting bracket 11 is fixed on the rotating mounting table 1, and further connection is performed with the connecting bracket 11 to ensure the installation stability of the overall tooling.

[0028] After the display panel substrate is grasped and positioned, due to the large overall area, there are edge parts outside the detection area, which may cause deformation. Therefore, an adjustable support frame 6 is also provided on the rotating mounting table 1. The support frame 6 is equipped with multiple vacuum suction nozzles located on both sides of the vacuum adsorption module 4. The support frame 6 is adjusted according to the edge distribution of the display panel to allow the vacuum suction nozzle to evenly adsorb the display panel. Therefore, the entire display panel is grasped flatly in combination with the vacuum adsorption module 4 to reduce the risk of deformation of the display panel, especially to ensure the flatness of the detection area, meet the visual function of the equipment, and can more accurately find the alignment mark and perform PIN (pin) docking more accurately to complete the detection process.

[0029] Specifically, a buffer spring 7 for abutting against the slider 3 is installed on the slide seat 2, and the slider 3 is pushed by the buffer spring 7 to ensure that the vacuum adsorption module 4 and the display panel are stably attached and adsorbed, thereby improving the alignment accuracy and transplanting efficiency.

[0030] Specifically, the support frame 6 can be adjusted to achieve the installation position of the vacuum suction nozzle to achieve the effect of uniformly grasping the edge of the display panel. Therefore, the support frame 6 includes a first support block 61 rotatably installed on both sides of the rotating mounting table 1, and a lateral adjustment block 62 is provided at one end of the first support block 61 close to the vacuum adsorption module 4. The lateral adjustment block 62 is connected to a first mounting block 63 by an adjusting screw, and the first mounting block 63 is installed with a first vacuum suction nozzle 8 located on one side of the vacuum adsorption module 4; the position of the first mounting block 63 on the lateral adjustment block 62 is adjusted by adjusting the screw, so that the spacing distance between the first vacuum adsorption nozzle and the vacuum adsorption module 4 is adjusted.

[0031] At the same time, the angle of the first support block 61 relative to the rotating mounting platform 1 can be adjusted by adjusting the screws.

[0032] Furthermore, a strip hole 64 is provided on the end of the first supporting block 61 away from the first mounting block 63, and a second mounting block 65 and a third mounting block 66 with adjustable angles are installed on the strip hole 64 by adjusting screws. A second vacuum suction nozzle 9 is installed at the end of the second mounting block 65, and a third vacuum suction nozzle 10 is installed at the end of the third mounting block 66. After adjusting the angle and position of the second mounting block 65 and the third mounting block 66 by adjusting the screws, the positions of the second vacuum suction nozzle 9 and the third vacuum suction nozzle 10 are adsorbed and grasped accordingly according to the distribution of the edge of the display panel as much as possible.

[0033] Therefore, the entire support frame 6 can be adaptively adjusted when adapting to display panels of different areas. Based on the vacuum adsorption module 4, the relative positions of the first vacuum suction nozzle 8, the second vacuum suction nozzle 9 and the third vacuum suction nozzle 10 are adjusted to achieve balanced grasping of the display panel as a whole.

[0034] Specifically, the second mounting block 65 is arranged vertically to the first supporting block 61 , so that the second vacuum suction nozzle 9 can perform negative pressure suction and grasping on the middle edge of the display panel as much as possible.

[0035] The third mounting block 66 is arranged obliquely with respect to the first supporting block 61 . By adjusting the angle and position of the third mounting block 66 , the third vacuum suction nozzle 10 is adaptively gripped by negative pressure at the rear edge of the display panel.

[0036] In order to ensure that the display panel remains balanced after being grasped, the suction ports of the first vacuum suction nozzle 8 , the second vacuum suction nozzle 9 and the third vacuum suction nozzle 10 are located in the same plane.
