[0045] When it is needed to assemble and adhere the glass panel and the display screen, the display screen with the surface glued can be arranged on the upper portion of the first positioning assembly 20 and the glued surface faces upwards, at this time, the first positioning assembly 20 positions the display screen, then the glass panel is arranged inside the second positioning assembly 30, the second positioning assembly 30 positions the glass panel, then the first driving assembly 50 drives the pressing assembly 40 and the second positioning assembly 30 to move downwards, the second positioning assembly 30 moves downwards and drives the glass panel to move downwards synchronously, when the glass panel moves downwards to adhere to the display screen, the pressing assembly 40 presses the glass panel, so that the glass panel and the display screen are bonded to each other, when the bonding between the glass panel and the display screen is completed, the first driving assembly 50 drives the pressing assembly 40 and the second positioning assembly 30 to move upwards, so that the pressing assembly 40 and the second positioning assembly 30 are reset, during the process, the second driving assembly 60 drives the pushing assembly 70 to move upwards compared with the first positioning assembly 20, so that the bonded glass panel and display screen are pushed away from the upper portion of the first positioning assembly 20, so that the workers can easily pick up the glass panel and the display screen.

[0046] Please refer to Figure 1 and Figure 5In one embodiment, the first positioning assembly 20 comprises a positioning seat 201 and four first L-shaped positioning blocks 202. The positioning seat 201 is fixedly arranged on the upper portion of the assembling table 10. The four first L-shaped positioning blocks 202 are fixedly arranged on the four corner positions of the upper portion of the positioning seat 201. The four first L-shaped positioning blocks 202 form a rectangle with the same area as the display screen.

[0047] When the glass panel needs to be assembled and attached to the display screen, the display screen with the surface being glued can be placed on the upper portion of the positioning seat 201, and the glued surface faces upward. At this time, the four first L-shaped positioning blocks 202 act on the four corner positions of the display screen, thereby positioning the display screen.

[0048] Please refer to Figure 1 and Figure 4 In one embodiment, the second positioning assembly 30 comprises four second L-shaped positioning blocks 301 and four first sliding sleeves 302. The four first sliding sleeves 302 are slidingly arranged outside the four support guide rods 101. The four second L-shaped positioning blocks 301 are fixedly arranged on the side walls of the four first sliding sleeves 302. The four second L-shaped positioning blocks 301 form a rectangle with the same area as the glass panel. The pressing assembly 40 comprises a pressing plate 401, a support plate 402, four second sliding sleeves 403, and four first elastic members 404. The pressing plate 401 is fixedly arranged on the bottom of the support plate 402. The four second sliding sleeves 403 are fixedly arranged on the four corner positions of the support plate 402. The four second sliding sleeves 403 are slidingly arranged outside the four support guide rods 101. The four first elastic members 404 are connected between the four first sliding sleeves 302 and the four second sliding sleeves 403. The four first elastic members 404 provide elastic support for the four first sliding sleeves 302.

[0049] Initially, the pressing plate 401 is located above the four sets of second L-shaped positioning blocks 301, and after the display screen is positioned on the upper part of the positioning seat 201 and the positioning is completed, the staff can place the glass panel between the four sets of second L-shaped positioning blocks 301, and at this time the four sets of second L-shaped positioning blocks 301 clamp the four corners of the glass panel to realize the positioning of the glass panel. Then the first driving assembly 50 drives the supporting plate 402 and the pressing plate 401 to move downward synchronously, and when the supporting plate 402 moves downward, it drives the four sets of second sliding sleeves 403 to slide downward along the four sets of supporting guide rods 101 respectively, and when the four sets of second sliding sleeves 403 slide downward, they push the four sets of second sliding sleeves 302 to slide downward synchronously outside the four sets of supporting guide rods 101 through the four sets of first elastic members 404, thereby driving the four sets of second L-shaped positioning blocks 301 to move downward synchronously, and when the four sets of second L-shaped positioning blocks 301 move downward, they drive the glass panel to move downward, and when the glass panel moves downward to adhere to the display screen below, the four sets of second L-shaped positioning blocks 301 act on the upper parts of the four sets of first L-shaped positioning blocks 202 respectively and then stop moving downward, and the pressing plate 401 acts on the glass panel during subsequent downward movement, thereby exerting a downward pressure on the glass panel to make the glass panel adhere to the display screen. During the subsequent upward movement of the supporting plate 402, the four sets of second sliding sleeves 403 continue to slide downward outside the four sets of supporting guide rods 101, and at this time the four sets of first elastic members 404 are stressed and compressed; after the glass panel adheres to the display screen, the first driving assembly 50 drives the supporting plate 402 and the pressing plate 401 to move upward, and when the supporting plate 402 moves upward, it drives the four sets of second sliding sleeves 403 to slide upward outside the four sets of supporting guide rods 101, and when the four sets of second sliding sleeves 403 slide upward, they pull the four sets of first sliding sleeves 302 to make the four sets of first sliding sleeves 302 slide upward outside the four sets of supporting guide rods 101 through the four sets of first elastic members 404 respectively, thereby driving the four sets of second L-shaped positioning blocks 301 to move upward, and realizing the resetting of the pressing plate 401 and the four sets of second L-shaped positioning blocks 301. During this process, the glass panel is retained on the upper surface of the display screen.

[0050] See Figure 6 and Figure 7In one embodiment, the second driving assembly 60 comprises a first elastic member 601, slide rods 602 and rollers 603, the slide rods 602 are provided in two groups, one end of the slide rods 602 is slidably connected with the side wall of the support plate 402, and the other end extends to the side of the pressing plate 401 and is rotatably connected with a group of the rollers 603, the first elastic member 601 is provided in two groups, and the first elastic members 601 are arranged on one side of the slide rods 602 respectively, for providing elastic support for the slide rods 602 respectively, two groups of accommodating grooves 2011 are formed in the upper part of the positioning seat 201, the top pushing assembly 70 comprises a push rod 701, a swing rod 702 and an extension plate 703, the swing rod 702 is provided in two groups, and the swing rods 702 are arranged on the side of the positioning seat 201, the push rod 701 is provided in two groups, and the push rods 701 are embedded in the accommodating grooves 2011 respectively, one end of the push rods 701 is connected with the swing rod 702 respectively, two groups of rotating shafts 2012 are fixedly arranged on the side wall of the positioning seat 201, and one end of the rotating shafts 2012 away from the positioning seat 201 is connected with the swing rod 702 respectively, the extension plate 703 is provided in two groups, and the extension plates 703 are fixedly arranged on the side wall of the swing rod 702 respectively.

[0051] The two groups of push rods 701 are initially embedded in the inner sides of the two groups of accommodating grooves 2011, and the two groups of swing rods 702 are in an inclined distribution. When the first driving assembly 50 drives the supporting plate 402, the pressing plate 401 and the glass panel to move downward, the supporting plate 402 drives the two groups of sliding rods 602 and the two groups of rollers 603 to move downward synchronously. When the glass panel is attached to the upper surface of the display screen, the two groups of rollers 603 act on the upper parts of the two groups of extension plates 703 respectively. With the subsequent continuous downward movement of the supporting plate 402, the two groups of sliding rods 602 and the two groups of rollers 603 move further downward. The two groups of rollers 603 are pushed by the two groups of extension plates 703 and in turn drive the two groups of sliding rods 602 to slide along the side walls of the supporting plate 402. The two groups of first elastic members 601 are compressed under stress, and the two groups of rollers 603 roll downward along the upper surfaces of the two groups of extension plates 703 respectively. When the two groups of rollers 603 roll away from the lower ends of the two groups of extension plates 703 respectively, the two groups of first elastic members 601 push the two groups of sliding rods 602 respectively so that the two groups of sliding rods 602 slide reversely along the side walls of the supporting plate 402, in turn driving the two groups of rollers 603 to move reversely to positions below the two groups of extension plates 703. In the above process, the two groups of push rods 701 are embedded in the interiors of the two groups of accommodating grooves 2011 respectively, so the two groups of swing rods 702 cannot rotate downward compared with the two groups of rotating shafts 2012. When the adhesion between the glass panel and the display screen is completed, the first driving assembly 50 drives the supporting plate 402 and the pressing plate 401 to move upward. The supporting plate 402 drives the two groups of sliding rods 602 and the two groups of rollers 603 to move upward synchronously. When the two groups of rollers 603 move upward, they act on the bottoms of the two groups of extension plates 703 respectively, in turn applying a pushing force upward to the two groups of extension plates 703. When the two groups of extension plates 703 are pushed, they in turn drive the two groups of swing rods 702 to rotate compared with the two groups of rotating shafts 2012, in turn driving the two groups of push rods 701 to rotate upward. When the two groups of push rods 701 rotate upward, they rotate out of the interiors of the two groups of accommodating grooves 2011 respectively, and push the glass panel and the display screen, which are integrated, away from the upper part of the positioning seat 201, in turn facilitating the staff to pick them up. When the glass panel and the display screen are picked up from the upper part of the positioning seat 201, the two groups of rollers 603 roll away from the upper ends of the two groups of extension plates 703 respectively. At this time, the two groups of push rods 701 drive the two groups of swing rods 702 to rotate downward compared with the two groups of rotating shafts 2012 through their own gravity. The two groups of push rods 701 re-embed in the interiors of the two groups of accommodating grooves 2011, in turn realizing the reset of the two groups of push rods 701.

[0052] Please refer to Figure 6In one embodiment, the support plate 402 side wall is fixedly provided with a first limiting block 4021, a first guide rail 4022 and a second limiting block 4023, the first limiting block 4021 and the second limiting block 4023 are oppositely distributed, the first guide rail 4022 is arranged between the first limiting block 4021 and the second limiting block 4023, the sliding rod 602 is in sliding fit with the first guide rail 4022, one end of the first elastic member 601 is connected with the second limiting block 4023, and the other end is connected with the sliding rod 602, so as to provide elastic support for the sliding rod 602.

[0053] When the roller 603 moves downward and acts on the upper part of the extension plate 703, the sliding rod 602 is stressed and then slides along the first guide rail 4022, and the first elastic member 601 is stressed and compressed. When the roller 603 rolls away from the lower end of the extension plate 703, the first elastic member 601 pushes the sliding rod 602 to make the sliding rod 602 slide reversely along the first guide rail 4022, thereby driving the roller 603 to move reversely, so that the roller 603 moves to a position below the extension plate 703, and when the roller 603 moves upward subsequently, the roller 603 can act on the bottom of the extension plate 703, thereby driving the swing lever 702 to rotate, and the push rod 701 pushes the bonded glass panel and display screen away from the upper part of the positioning seat 201, so that the staff can easily pick up the glass panel and display screen.

[0054] Please refer to Figure 7 In one embodiment, the side wall of the positioning seat 201 is further fixedly provided with a support 2013 below the two groups of swing levers 702, and the second elastic member 704 is connected between the support 2013 and the bottom wall of the swing lever 702, so as to provide elastic tension for the swing lever 702.

[0055] When the roller 603 moves upward and acts on the bottom of the extension plate 703, thereby driving the swing lever 702 to rotate compared with the rotating shaft 2012, the second elastic member 704 is stretched. When the roller 603 rolls away from the upper end of the extension plate 703, the second elastic member 704 pulls the swing lever 702 to make the swing lever 702 quickly rotate reversely, thereby driving the push rod 701 to quickly fall back to the inside of the accommodating groove 2011, so as to realize the quick reset of the push rod 701.

[0056] Please refer to Figure 7 In one embodiment, the side wall of the positioning seat 201 is provided with an arc-shaped groove 2014 and a straight groove 2015, the arc-shaped groove 2014 and the straight groove 2015 are in communication with each other, one group of swing levers 702 is further fixedly provided with a sliding pin 707 on the side wall, the group of swing levers 702 rotates and slides with the corresponding rotating shaft 2012, and one end of the sliding pin 707 away from the swing lever 702 extends to the inside of the arc-shaped groove 2014.

[0057] When the two groups of rollers 603 act on the bottom of the two groups of extension plates 703, thereby driving the two groups of swing rods 702 and the two groups of push rods 701 to rotate, one of the two groups of swing rods 702 drives the slide pin 707 to slide along the inside of the arc-shaped groove 2014, at this time, the two groups of push rods 701 are synchronously turned out from the inside of the corresponding accommodation groove 2011, thereby separating the glass panel and the display screen adhered together from the upper part of the positioning seat 201. When the glass panel and the display screen are separated from the positioning seat 201 by a certain distance, the slide pin 707 slides from the inside of the arc-shaped groove 2014 into the inside of the straight groove 2015 and continues to slide along the inside of the straight groove 2015. At this time, the slide pin 707 deviates from the original rotation track and drives the corresponding swing rod 702 to slide relative to the rotation shaft 2012. When the swing rod 702 slides, it pulls the corresponding push rod 701 to deviate from the original rotation track, thereby lowering the height of the push rod 701 relative to the other group of push rods 701. In this way, a height difference is formed between the two groups of push rods 701, so that the glass panel and the display screen separated from the positioning seat 201 by the two groups of push rods 701 are in an inclined state. The inclined glass panel and display screen slide from above the positioning seat 201 to the side of the positioning seat 201 and fall onto the upper part of the assembly table 10, thereby realizing automatic unloading of the glass panel and the display screen from above the positioning seat 201, thereby preventing the glass panel and the display screen from falling back onto the upper part of the positioning seat 201 due to the failure of the worker to pick them up in time.

[0058] Please refer to Figure 7 In one embodiment, a second guide rail 706 is fixedly arranged on the sidewall of one of the swing rods 702, and a sliding block 705 is slidably arranged on the second guide rail 706, and the sliding block 705 is rotationally connected to the corresponding rotation shaft 2012.

[0059] When the slide pin 707 slides along the inside of the straight groove 2015, the straight groove 2015 pulls the slide pin 707, thereby driving the swing rod 702 and the second guide rail 706 to slide relative to the sliding block 705, while the sliding block 705 rotates relative to the rotation shaft 2012.

[0060] In one embodiment, the first drive assembly 50 can be a hydraulic cylinder or a linear motor, which is not limited here.

[0061] In one embodiment, the first elastic member 601 and the second elastic member 704 can be springs or metal springs, which are not limited here.

[0062] In the embodiment of the present application, when the glass panel needs to be assembled and attached with the display screen, the display screen after surface dispensing can be placed on the upper part of the first positioning assembly 20, and the dispensing surface faces upward. At this time, the first positioning assembly 20 positions the display screen, and then the glass panel is placed inside the second positioning assembly 30, and the second positioning assembly 30 positions the glass panel. Then the first driving assembly 50 drives the pressing assembly 40 and the second positioning assembly 30 to move downward, and the second positioning assembly 30 moves downward to drive the glass panel to move downward synchronously. When the glass panel moves downward to attach with the display screen, the pressing assembly 40 presses the glass panel, so that the glass panel and the display screen are mutually adhered. When the adhesion between the glass panel and the display screen is completed, the first driving assembly 50 drives the pressing assembly 40 and the second positioning assembly 30 to move upward, so as to reset the pressing assembly 40 and the second positioning assembly 30. In this process, the second driving assembly 60 drives the pushing assembly 70 to move upward compared with the first positioning assembly 20, so as to push the adhered glass panel and display screen away from the upper part of the first positioning assembly 20, thereby facilitating the workers to smoothly pick up the glass panel and the display screen. Compared with the prior art, after the glass panel and the display screen are assembled and attached, the glass panel and the display screen can be automatically pushed away from the inside of the positioning assembly, so that the glass panel and the display screen can be conveniently picked up, thereby improving the assembly and attachment efficiency of the glass panel and the display screen.

[0063] The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
