[0041] The advantages and features of the present invention and methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in a variety of different forms. These embodiments are provided merely to complete the disclosure of the present invention and enable those skilled in the art to fully understand the scope of the present invention. The present invention is limited only by the scope of the claims. The same reference numerals represent the same components throughout the specification.

[0042] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0043] like Figures 2 to 4 As shown, the display panel adsorption structure of this embodiment includes a support assembly 100 , a mounting sleeve 200 , a suction cup assembly 300 , a limiting assembly 400 and an elastic portion 500 .

[0044] Among them, multiple mounting sleeves 200 are arranged at intervals in the support assembly 100, and the mounting sleeves 200 are fixedly connected to the support assembly 100; the suction cup assembly 300 includes a hard ventilation tube 310 and a suction cup 320, and a hard ventilation tube 310 is installed in each mounting sleeve 200, and a suction cup 320 is connected to one end of the hard ventilation tube 310; the limiting assembly 400 includes a first limiting portion 410, a second limiting portion 420 and a third limiting portion 430, and the first limiting portion 410, the second limiting portion 420 and the third limiting portion 430 are arranged at intervals along the axial direction of the mounting sleeve 200, and the first limiting portion 410 and the third limiting portion 430 are arranged at intervals along the axial direction of the mounting sleeve 200, and the first limiting portion 410 and the third limiting portion 430 is fixed on the mounting sleeve 200 and extends into the mounting sleeve 200, the inner peripheries of the first limiting portion 410 and the third limiting portion 430 are clearance-matched with the outer periphery of the hard ventilation tube 310, the second limiting portion 420 is fixed on the outer periphery of the hard ventilation tube 310, the outer periphery of the second limiting portion 420 is clearance-matched with the inner periphery of the mounting sleeve 200, and the second limiting portion 420 selectively abuts against the third limiting portion 430; the elastic portion 500 is sleeved on the outer periphery of the hard ventilation tube 310, and the two ends of the elastic portion 500 along the axial direction of the hard ventilation tube 310 are respectively connected or abutted with the first limiting portion 410 and the second limiting portion 420.

[0045] It can be understood that in this embodiment, the hard vent tube 310 is passed through the mounting sleeve 200, and the hard vent tube 310 is restricted in the mounting sleeve 200 by the first limiting portion 410, the second limiting portion 420 and the third limiting portion 430 installed between the hard vent tube 310 and the mounting sleeve 200 to prevent the hard vent tube 310 from being separated from the mounting sleeve 200. At the same time, the elastic portion 500 is sleeved on the outside of the hard vent tube 310, and the elastic portion 500 is moved along the hard vent tube 310. The two axial ends are connected to or abut the first limiting portion 410 and the second limiting portion 420, respectively. Under the action of the elastic portion 500 and the first limiting portion 410, the second limiting portion 420, and the third limiting portion 430, the suction cup 320 can overcome the force of the elastic portion 500 and move along the axial direction of the mounting sleeve 200 when adsorbing the display panel. At the same time, the elastic portion 500 can make the suction cup 320 press against the surface of the display panel to achieve adsorption, reducing the risk of wear, air leakage, and other adsorption abnormalities of the suction cup 320. The display panel adsorption structure of this embodiment also has a good adsorption effect on curved display panels.

[0046] In this embodiment, the second limiting portion 420 and the third limiting portion 430 selectively abut against each other, which means that when the convex area of ​​the curved display panel squeezes the suction cup 320, the suction cup 320 overcomes the force of the elastic portion 500 and moves upward, and at this time the second limiting portion 420 and the third limiting portion 430 are separated; when the suction cup 320 adsorbs the concave or flat area of ​​the curved display panel, the suction cup 320 overcomes the force of the elastic portion 500 and moves downward, and at this time the extreme position of the movement of the suction cup 320 is the abutment between the second limiting portion 420 and the third limiting portion 430.

[0047] In this embodiment, the elastic portion 500 can provide a buffering effect to reduce wear on the suction cup 320. When the display panel is not fully supported or bends under other circumstances, the elastic portion 500 can provide a certain buffering effect on the suction cup 320, preventing the suction cup 320 from being severely squeezed by the display panel.

[0048] In this embodiment, the elastic portion 500 is selected from a spring. Of course, the same is also applicable to other elastic structures. Next, the display panel adsorption structure of this embodiment is further described with reference to the accompanying drawings, taking a spring as an example.

[0049] Exemplarily, the rigid ventilation tube 310 has a first end 3101 and a second end 3102 along its axial direction, and the mounting sleeve 200 has a third end 2001 and a fourth end 2002 along its axial direction, wherein the third end 2001 is adjacent to the first end 3101, and the fourth end 2002 is adjacent to the second end 3102. The first end 3101 is used to mount a suction cup 320, and the second end 3102 is used to connect to a delivery pipe (not shown in the figure). The second limiting portion 420 is provided on the outer periphery of the rigid ventilation tube 310 adjacent to the first end 3101, the third limiting portion 430 is adjacent to the third end 2001 of the mounting sleeve 200, and the first limiting portion 410 is adjacent to the fourth end 2002 of the mounting sleeve 200. One end of the spring abuts against the first limiting portion 410, and the other end abuts against the second limiting portion 420. Figure 2 As shown, the spring in the initial state is always in a compressed state, and the second limiting portion 420 abuts against the third limiting portion 430; when the suction cup 320 is squeezed, the hard vent tube 310 overcomes the elastic force of the spring and further compresses the spring through the second limiting portion 420. At this time, the hard vent tube 310 can drive the suction cup 320 to move in a direction close to the fourth end 2002, as shown in FIG. Figure 3 As shown, the second limiting portion 420 is separated from the third limiting portion 430; when the spring is connected to the first limiting portion 410 and the second limiting portion 420 respectively, the spring in the initial state can be in a compressed state or in a natural state without elasticity. When the suction cup 320 is squeezed, the hard ventilation tube 310 overcomes the elastic force of the spring and compresses the spring through the second limiting portion 420, so that the suction cup 320 can stably adsorb the display panel. The details are not repeated here.

[0050] Among them, the first limiting portion 410, the second limiting portion 420 and the third limiting portion 430 can be an annular structure, or can be composed of two sub-limiting blocks with an angle of 180°, and the details are not repeated here.

[0051] Furthermore, the support assembly 100 includes a support plate 110, a first nut 120 and a second nut 130. The outer periphery of the mounting sleeve 200 is provided with an external thread. The support plate 110 is provided with a plurality of mounting holes 140 corresponding one to one with the mounting sleeve 200. The mounting sleeve 200 passes through the mounting holes 140 and is screwed onto the first nut 120 and the second nut 130 respectively. The first nut 120 and the second nut 130 are respectively fitted onto the two side surfaces of the support plate 110 along its thickness direction.

[0052] In this embodiment, after the mounting sleeve 200 passes through the mounting hole 140 on the support plate 110, the mounting sleeve 200 can be stably fixed on the support plate 110 through the double nut structure design. The nut is locked to facilitate the disassembly and assembly of the mounting sleeve 200.

[0053] Furthermore, the first limiting portion 410 and / or the third limiting portion 430 do not protrude from the outer periphery of the mounting sleeve 200, so as to facilitate the installation and fixation of the mounting sleeve 200. For example, the third limiting portion 430 is installed at the third end 2001 of the mounting sleeve 200, and the edge of the third limiting portion 430 protrudes from the outer periphery of the mounting sleeve 200. The first limiting portion 410 is installed on the inner periphery of the mounting sleeve 200 adjacent to the fourth end 2002 of the mounting sleeve 200. When installing the mounting sleeve 200, the fourth end 2002 of the mounting sleeve 200 can be passed through the first nut 120, the mounting hole 140, and the second nut 130. After adjusting the position of the mounting sleeve 200, the first nut 120 and the second nut 130 are screwed so that the first nut 120 and the second nut 130 are respectively in contact with the two side surfaces of the support plate 110, thereby fixing the mounting sleeve 200 on the support plate 110.

[0054] Of course, the third limiting portion 430 in this embodiment is not limited to being installed on the third end 2001 of the mounting sleeve 200, and the first limiting portion 410 is not limited to being installed on the inner circumference of the mounting sleeve 200. In other embodiments, the third limiting portion 430 can also be installed on the inner circumference of the mounting sleeve 200, and the first limiting portion 410 can also be installed on the end of the mounting sleeve 200, so as to cooperate with the second limiting portion 420 and the spring to limit the hard ventilation tube 310 from detaching from the mounting sleeve 200.

[0055] In order to accommodate the relatively long hard vent tube 310 and the mounting sleeve 200 and to prevent the mounting sleeve 200 from bending and deforming when the suction cup 320 is squeezed, the present embodiment designs a plurality of support plates 110, and all support plates 110 are spaced apart along the axial direction of the mounting sleeve 200, that is, a first nut 120 and a second nut 130 are respectively provided on the two side surfaces of each support plate 110 corresponding to each mounting sleeve 200. Figure 2 As shown, there are two support plates 110. In other embodiments, the number and spacing of the support plates 110 can be adjusted according to actual conditions.

[0056] This embodiment also provides a display panel flipping device, such as Figures 5 to 8 As shown, the display panel flipping device of this embodiment includes the display panel adsorption structure of the above embodiment as well as a frame 600 , a first driving assembly 700 , and a second driving assembly 800 .

[0057] The frame 600 is composed of two Figure 5 The mounting portions 610 spaced apart along the second direction ( Figure 5The first direction is perpendicular to the second direction, and a group of adsorption mechanisms are respectively provided on opposite sides of the two mounting portions 610. Each group of adsorption mechanisms includes a plurality of display panel adsorption structures arranged at intervals, and the suction cups 320 of the two groups of adsorption mechanisms are facing each other; the first driving component 700 includes a plurality of driving parts, and the driving parts correspond to the display panel adsorption structures one by one. The driving parts are installed on the mounting portions 610 and connected to the supporting components 100 of the corresponding display panel adsorption structures. The first driving component 700 is used to drive the adsorption mechanism to adsorb and fix the display panel 1; the second driving component 800 is connected to the frame 600, and is used to drive the frame 600 to drive the adsorption mechanism to rotate around an axis parallel to the second direction to flip the display panel 1.

[0058] In the initial state, the two mounting parts 610 are distributed up and down, and the two groups of adsorption mechanisms are spaced apart. The display panel 1 together with the jig 2 (the display panel 1 is located on the jig 2, and the packaging structure of the display panel 1 faces downward) are carried between the two groups of adsorption mechanisms by the robot. Each group of driving parts above the display panel 1 is started in turn to drive the corresponding suction cup 320 to adsorb the display panel 1, so that the display panel 1 is gradually separated from the jig 2. Figure 6 After the manipulator sends the fixture 2 out, the drive unit located below the display panel 1 is started synchronously, driving the suction cup 320 to adhere to the display panel 1, as shown in FIG. Figure 7 The two adsorption mechanisms work together to secure the display panel 1. The second drive assembly 800 then drives the frame 600, causing the adsorption mechanisms and the display panel 1 to flip 180°, flipping the display panel 1. After flipping, the packaging structure of the display panel 1 faces upward. The upper and lower adsorption mechanisms then release the display panel 1 in sequence. The robot then carries the display panel 1 to the next station, preventing the robot from contacting and damaging the packaging structure on the display panel 1.

[0059] In each group of adsorption mechanisms, all display panel adsorption structures are spaced apart along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. Each group of driving parts can start from the edge of the display panel 1 and move along the third direction ( Figure 8 The Z direction (which is perpendicular to the X and Y directions) is started in sequence to drive the corresponding suction cups 320 to absorb the display panel 1, so that the display panel 1 is gradually separated from the fixture 2.

[0060] Each set of driving units includes at least two cylinders 710 installed at intervals on the mounting portion 610. The cylinders 710 are in transmission connection with the support assembly 100 and are used to drive the support assembly 100 to drive the mounting sleeve 200 and the suction cup assembly 300 to move along the first direction. For example, each set of driving units includes two cylinders 710, which are in transmission connection with the support plate 110. The cylinders 710 drive the mounting sleeve 200, the hard vent tube 310, and the suction cup 320 to move up and down along the first direction by driving the support plate 110. The number of cylinders 710 in each set of driving units in this embodiment is not limited to two, and can also be three or even more, depending on the length of the support plate 110, so as to stably drive the support plate 110 to move along the first direction.

[0061] Furthermore, the second drive assembly 800 includes a mounting frame 810, a motor 820, and a rotating shaft 830. The mounting frame 810 includes two side panels 811 spaced apart along the second direction, with the frame 600 located between the two side panels 811. The motor 820 is mounted on one of the side panels 811, with the output shaft of the motor 820 rotatably connected to the corresponding connecting portion 620. The rotating shaft 830 is mounted on the other side panel 811, connected to the other connecting portion 620, and capable of rotating relative to the side panel 811. When the motor 820 is activated, it drives the frame 600 and the rotating shaft 830 to rotate. When the frame 600 rotates 180°, the display panel 1 is flipped.

[0062] For example, the mounting frame 810 of this embodiment further includes a base 812, and two side panels 811 are fixed to the base 812 at intervals along the second direction. This structural design can improve the structural stability of the mounting frame 810.

[0063] Furthermore, the second drive assembly 800 of this embodiment further includes a bearing 840, which is mounted on the side plate 811 and connected to the rotating shaft 830. That is, the rotating shaft 830 is rotatably connected to the side plate 811 via the bearing 840. The provision of the bearing 840 can improve the smoothness of the rotation of the rotating shaft 830, thereby reducing the power consumption of the motor 820.

[0064] like Figure 8 As shown, the display panel flipping device in this embodiment also includes two groups of support parts 900, and one group of support parts 900 is provided on the opposite side of the two mounting parts 610. The support part 900 includes a plurality of support rods 910 fixed on the mounting part 610 at intervals, and the support rods 910 are arranged at intervals from the display panel adsorption structure; the first driving component 700 can drive the suction cup 320 of the display panel adsorption structure to selectively protrude from the end of the support rod 910 away from the mounting part 610.

[0065] In the initial state, the suction cups 320 of the two sets of adsorption mechanisms do not exceed the end of the support rod 910 away from the mounting portion 610, and the two sets of adsorption mechanisms are distributed in an upper and lower manner. When the robot arm carries the fixture 2 together with the display panel 1 on the fixture 2 to between the upper and lower sets of adsorption mechanisms, as shown in FIG. Figure 5 As shown, first place the jig 2 on the support rod 910 below. Each set of driving units located above the display panel 1 starts from the edge of the display panel 1 and starts to be activated in sequence along the third direction (Z direction) to drive the corresponding suction cup 320 to absorb the display panel 1, so that the display panel 1 is gradually separated from the jig 2, as shown in FIG. Figure 6 As shown, until the display panel 1 is completely separated from the fixture 2. The robot carries the fixture 2 out, and the driving unit located below the display panel 1 is started synchronously, driving the suction cup 320 to protrude from the end surface of the support rod 910 and adhere to the display panel 1. Figure 7 As shown, the two adsorption mechanisms work together to achieve adsorption and fixation of the display panel 1. Then, the motor 820 drives the frame 600 to drive the adsorption mechanism and the display panel 1 to flip 180 degrees, thereby achieving flipping of the display panel 1.

[0066] In this embodiment, support rods 910 are respectively installed on the two mounting parts 610. Any set of adsorption mechanisms with support rods 910 can be located below the display panel 1 and the fixture 2 without special adjustment, thereby improving the operational convenience of the display panel flipping device.

Therefore, it should be understood that the above embodiments are illustrative and not restrictive in all aspects.
