[0031] Please also refer to Figures 1 to 4 , the display screen line separation device provided in the embodiment of the present application is now described.

[0032] Please also refer to Figure 1 and Figure 2The display line separation device includes a workbench 10, a positioning mechanism 20, a translation drive and a cutting mechanism 40. The workbench 10 has a cutting area 11; the positioning mechanism 20 is used to fix the display screen; the translation drive mechanism 30 is connected to the positioning mechanism 20, and is used to drive the positioning mechanism 20 to reciprocate along the first direction F1 in the cutting area 11; the cutting mechanism 40 includes a support frame 41 and a winding assembly 42 and a tension adjustment assembly 43 arranged on the support frame 41. The winding assembly 42 includes a first guide wheel 421, a second guide wheel 422 spaced apart from the first guide wheel 421, a cutting line 423 wound around the first guide wheel 421 and the second guide wheel 422, and a line driver 424 connecting the cutting line 423. The cutting line 423 is arranged across the cutting area 11 along a second direction F2 perpendicular to the first direction F1. The line driver 424 is used to drive at least a portion of the cutting line 423 to reciprocate along the second direction F2. The tension adjustment assembly 43 is connected to the second guide wheel 422 to adjust the position of the second guide wheel 422.

[0033] The display screen includes a display panel, a glass panel, and an adhesive layer, wherein the display panel is bonded to the glass panel via the adhesive layer, and the adhesive of the adhesive layer can be OCA.

[0034] Optionally, the cutting wire 423 may be, but is not limited to, diamond wire or the like.

[0035] Compared with the prior art, the display line separation device provided by the present application is different from the prior art. When working, the display screen to be cut is fixed on the positioning mechanism 20, and the translation drive mechanism 30 drives the positioning mechanism 20 carrying the display screen to move along the first direction F1, so that the adhesive layer of the display screen contacts the cutting line 423. The line driver 424 drives at least a portion of the cutting line 423 to reciprocate along the second direction F2, so that the cutting line 423 performs line cutting on the adhesive layer on the display screen along the second direction F2, thereby separating the display panel and the glass panel of the display screen. When the display line separation device provided by the present application performs line cutting on the adhesive layer of the display screen, it effectively prevents the display panel and the glass panel from bending, has a good cutting effect, is not easy to damage the display panel and the glass panel, and realizes automatic separation of the display screen, which is conducive to improving separation efficiency. In addition, the position of the second guide wheel 422 is adjusted by the tension adjustment component 43 to adjust the tension of the cutting line 423, so that the cutting line 423 maintains a preset tension, thereby achieving effective cutting of the display screen by the cutting line 423 and preventing the cutting line 423 from breaking due to excessive tension.

[0036] In one embodiment of this application, see Figure 1 and Figure 2 The positioning mechanism 20 includes a suction plate 21 , and the suction plate 21 is provided with suction holes 211 for adsorbing the display screen.

[0037] The suction hole 211 is connected to the vacuum module via an air pipe. When fixing the display screen, the display screen is first placed on the adsorption plate 21. The vacuum module evacuates the suction hole 211 via the air pipe, causing the suction hole 211 to adsorb the display screen onto the adsorption plate 21. By using vacuum adsorption to fix the display screen, the operation is simple and it is not easy to damage the display screen.

[0038] Optionally, there are multiple suction holes 211 , and the multiple suction holes 211 are distributed on the adsorption plate 21 at intervals.

[0039] In one embodiment of the present application, a plurality of adsorption regions are provided on the adsorption plate 21 . The areas of the plurality of adsorption regions are different in size, and each adsorption region is provided with a suction hole 211 .

[0040] By setting a plurality of adsorption areas of different sizes on the adsorption plate 21, it is possible to select an adsorption area of ​​corresponding size according to the size of the display screen, and then evacuate the adsorption holes of the adsorption area through the vacuum module so that the display screen is adsorbed in the adsorption area. In this way, display screens of various sizes can be fixed, thereby realizing separation of display screens of various sizes. For example, display screens larger than 10 inches and those smaller than 17 inches can be separated, making the display screen line separation device widely versatile.

[0041] It should be noted that the suction holes 211 in different adsorption areas may be interconnected or disconnected. In the case where the suction holes 211 in different adsorption areas are interconnected, when the display screen is placed in the adsorption area, the suction holes 211 not covered by the display screen need to be covered to prevent the vacuum effect from being damaged.

[0042] Optionally, three adsorption areas are provided on the adsorption plate 21 , and the three adsorption areas are distributed in sequence along the first direction F1 .

[0043] In one embodiment of this application, see Figure 2 The positioning mechanism 20 further includes a heating plate 22 , which is connected to the adsorption plate 21 .

[0044] The adsorption plate 21 is heated by the heating plate 22 , and then the heat is transferred to the display screen through the increased temperature of the adsorption plate 21 to soften the adhesive layer of the display screen, reduce the wire cutting resistance, and facilitate the cutting line 423 to cut the adhesive layer of the display screen.

[0045] Optionally, the heating plate 22 is fitted to the lower surface of the adsorption plate 21 and is fixedly connected to the adsorption plate 21 by screws or the like.

[0046] In one embodiment of this application, see Figure 2 The positioning mechanism 20 further includes a commutator 23 , the commutator 23 is connected to the adsorption plate 21 , and the translation drive mechanism 30 is connected to the commutator 23 .

[0047] The commutator 23 is used to drive the adsorption plate 21 to deflect horizontally. In this way, when the positioning mechanism 20 drives the display screen to move toward the cutting line 423 under the drive of the translation drive mechanism 30, the commutator 23 can drive the adsorption plate 21 to deflect horizontally, and then drive the display screen to deflect horizontally relative to the cutting line 423, so as to change the cutting angle of the cutting line 423 on the display screen, so that the cutting line 423 contacts the part where the width of the adhesive layer is reduced as much as possible, so as to reduce the contact area between the cutting line 423 and the adhesive layer, and then reduce the cutting resistance of the adhesive layer to the cutting line 423, so that the cutting line 423 can easily cut the adhesive layer.

[0048] Optionally, the commutator 23 may be, but is not limited to, an electric motor, a pneumatic motor, or a hydraulic motor.

[0049] In one embodiment of this application, see Figure 1 The adsorption plate 21 is provided with a avoidance groove 212 for avoiding the raised portion of the display screen.

[0050] For example, the back of the display screen has a raised portion. When the display screen is placed on the display screen, the back of the display screen faces the adsorption plate 21, and the raised portion on the back of the display screen is accommodated in the avoidance groove 212, so that the back of the display screen can fit with the adsorption plate 21, and the adsorption plate 21 can adsorb the display screen more stably.

[0051] Optionally, the avoidance groove 212 may be L-shaped or U-shaped, etc., and may be specifically designed according to the shape of the raised portion of the display screen.

[0052] Optionally, see Figure 2 The number of the first guide wheels 421 is four, two of which are located on one side of the cutting area 11, and the two first guide wheels 421 are spaced apart in the vertical direction, and the other two first guide wheels 421 are located on the other side opposite to the cutting area 11, and the two first guide wheels 421 are spaced apart in the vertical direction.

[0053] In one embodiment of this application, see Figure 2 The support frame 41 is a gantry frame and is arranged across the cutting area 11 along the second direction F2. The line driver 424 is arranged on the top of the support frame 41. The number of second guide wheels 422 and the tension adjustment assembly 43 are both two. The two second guide wheels 422 are respectively located on opposite sides of the cutting area 11, and the two tension adjustment assemblies 43 are respectively located on opposite sides of the cutting area 11 and are respectively connected to the two second guide wheels 422.

[0054] Optionally, the support frame 41 includes two vertical beams 411 and a horizontal beam 412 connecting the two vertical beams 411, the two vertical beams 411 are located on opposite sides of the cutting area 11, and the horizontal beam 412 is arranged across the cutting area 11, wherein the two first guide wheels 421 are arranged on one of the vertical beams 411, and the other two first guide wheels 421 are arranged on the other vertical beam 411, the two second guide wheels 422 are respectively arranged on the two vertical beams 411, the line drive 424 is arranged on the horizontal beam 412, and the two tension adjustment components 43 are respectively arranged on the two vertical beams 411.

[0055] In one embodiment of this application, see Figure 2 The line driver 424 is slidably disposed on the support frame 41 along the second direction F2 and can reciprocate along the second direction F2. The line driver 424 is connected to both ends of the cutting line 423.

[0056] When the line driver 424 moves along the second direction F2 on the support frame 41, it pulls the cutting line 423 in a clockwise motion, causing a portion of the cutting line 423 to cut the adhesive layer of the display screen in a direction opposite to the second direction F2. When the line driver 424 moves along the support frame 41 in a direction opposite to the second direction F2, it pulls the cutting line 423 in a counterclockwise motion, causing a portion of the cutting line 423 to cut the adhesive layer of the display screen in the second direction F2. It can be understood that when the line driver 424 reciprocates along the second direction F2 on the support frame 41, it causes one side of the cutting line 423 to release its length and the other side to compress its length, causing the cutting line 423 to perform a sawing-like cutting action, repeatedly cutting the adhesive layer of the display screen and effectively ensuring the cutting effect.

[0057] In one embodiment of this application, see Figure 2 and Figure 3 The tension adjustment assembly 43 includes a first fixed block 431 arranged on the support frame 41, a guide rod 432 connected to the first fixed block 431, a spring 433 sleeved on the guide rod 432, and a second fixed block 434 slidingly engaged with the guide rod 432. The two ends of the spring 433 respectively abut against the first fixed block 431 and the second fixed block 434, and the second guide wheel 422 is arranged on the second fixed block 434.

[0058] The spring 433 has an elastic force that maintains a preset tension in the cutting line 423. Specifically, when the cutting line 423 passes through the second guide wheel 422 and is released, the tension in the cutting line 423 decreases, and the spring 433 releases its elastic force. The spring 433 then drives the second fixed block 434 away from the first fixed block 431. The second fixed block 434 then drives the second guide wheel 422 away from the first guide wheel 421, increasing the distance between the second guide wheel 422 and the first guide wheel 421 to compensate for the released length of the cutting line 423 and maintain the preset tension in the cutting line 423. When the cutting line 423 passes through the second guide wheel 422 and is compressed, the tension in the cutting line 423 increases, and the second guide wheel 422 pushes the second fixed block 434 toward the first fixed block 431, reducing the distance between the second guide wheel 422 and the first guide wheel 421 to compensate for the compressed length of the cutting line 423 and maintain the preset tension in the cutting line 423. Simultaneously, the spring 433 is compressed. It can be understood that by passively adjusting the tension of the cutting line 423 in real time through the tension adjustment component 43, the resistance of the adhesive layer of the display screen and the line distance difference caused by the reciprocating motion of the cutting line 423 driven by the line driver 424 can be effectively offset, so that the cutting line 423 can effectively cut the adhesive layer of the display screen and the cutting line 423 is not easy to break.

[0059] Optionally, the tension adjustment assembly 43 includes two guide rods 432 and two springs 433, one end of the two guide rods 432 is connected to the first fixed block 431, and the other end of the two guide rods 432 is slidably engaged with the second fixed block 434, and the two springs 433 are respectively mounted on the two guide rods 432.

[0060] Optionally, a through hole is provided on the second fixing block 434 for the guide rod 432 to pass through, and the guide rod 432 passes through the through hole on the second fixing block 434 to achieve sliding fit between the second fixing block 434 and the guide rod 432 .

[0061] In one embodiment of this application, see Figure 2 The cutting mechanism 40 further includes a height adjustment component 44 for adjusting the height of the cutting line 423. By adjusting the height of the cutting line 423 by the height adjustment component 44, the cutting line can be aligned with the adhesive layer of the display screen, achieving accurate line cutting of the adhesive layer to adapt to different types of display screens.

[0062] Optionally, there are two height adjustment assemblies 44, located on opposite sides of the cutting area 11 and connected to the two vertical beams 411, respectively, to drive the vertical beams 411 to move upward and downward. It can be understood that the two height adjustment assemblies 44 drive the vertical beams 411 to move upward and downward, thereby driving the winding assembly 42 and the tension adjustment assembly 43 to move upward and downward, so that the cutting line 423 is aligned with the adhesive layer of the display screen.

[0063] See also Figure 4 The height adjustment component 44 includes a support leg 441, a lifting motor 442 arranged on the support leg 441, and an output shaft 443 connected to the lifting motor 442. The output shaft 443 is a threaded rod and is threadedly connected to the corresponding vertical beam 411 in the vertical direction. When the lifting motor 442 drives the output shaft 443 to rotate, it drives the vertical beam 411 to perform lifting and lowering movements.

[0064] Optionally, the vertical beam 411 may be slidably disposed on the support leg 441 along a vertical direction, so that the vertical beam 411 can be lifted and lowered along the support leg 441 .

[0065] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
