Description

Technical Field

[0001] The invention relates to the technical field of OLED substrate stripping, and in particular to an adaptive fixing structure for OLED stripping equipment. Background Art

[0002] In the field of display device production equipment, the components involved include glass substrates, cover plates, FPCs and various optical film materials. In the production process of OLED screens, an intermediate layer of glue (polyimide) is provided between the OLED screen (organic light-emitting display) and the glass substrate. The intermediate layer of glue needs to be removed by laser stripping. The laser is irradiated on the surface of the glass substrate, passes through the glass substrate and then shoots onto the intermediate glue layer to achieve the function of stripping the glue layer. In order to ensure that the laser effectively penetrates the substrate and reduce the obstruction caused by debris on the surface of the substrate, the surface of the glass substrate needs to be cleaned before laser stripping. The process used is grinding, that is, the grinding disc is pressed against the surface of the glass substrate, and the surface of the glass substrate is ground by rotating the grinding disc to separate the debris from the surface of the glass substrate and remove it. Then, the laser is irradiated on the surface of the glass substrate for stripping and removal.

[0003] In the prior art, before laser irradiation is performed on a glass substrate, the glass substrate needs to be fixed so that the glass substrate is placed facing upward, and then the surface of the fixed glass substrate is ground. Impurities generated during the grinding process will splash and fall onto the OLED screen. The impurities will interfere with subsequent laser irradiation and will be detrimental to peeling. In addition, since the sizes of OLED screens of different products are different, when fixing the OLED screen, the fixing device needs to be adjusted one-to-one according to each model, which takes a certain amount of time and effort, and the operation is not convenient enough.

[0031] The following will describe various embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0032] like Figures 1 to 11As shown, the technical solution adopted by the present invention is an adaptive fixing structure for an OLED peeling device, comprising a base 1, a rotating shaft 2, a base 3 and a lifting base, wherein the rotating shaft 2 is horizontally arranged on the base 1, one end of the rotating shaft 2 is transmission-connected to a power mechanism, and the other end is connected to the base 3, for driving the base 3 to rotate, a fixing plate 4 is fixedly arranged on the base 3, a clamping mechanism for fixing the OLED screen on the fixing plate 4 is arranged on the fixing plate 4, an adjusting plate 5 is arranged at the bottom of the fixing plate 4, and an adjusting mechanism for adjusting the distance between the adjusting plate 5 and the bottom of the fixing plate 4 is arranged on the base 3;

[0033] The lifting seat is provided with a turntable 14 and a grinding plate 15 installed on the turntable 14 . The turntable 14 is located below the base 3 .

[0034] like Figures 1-2 As shown, the present invention sets the base 3 on the rotating shaft 2. Driven by the power mechanism, the rotating shaft 2 can drive the base 3 to flip, and then drive the glass substrate of the OLED screen installed in the fixed disk 4 to face upward or downward. When installing the OLED screen, the opening of the fixed disk 4 is facing upward, and the distance between the adjusting plate 5 and the bottom of the fixed disk 4 is adjusted by the adjusting mechanism, so as to adjust the depth of the fixed disk 4, and then match the OLED screens of different thicknesses. After the OLED screen is placed in the fixed disk 4, it is clamped and fixed by the clamping mechanism. After the installation is completed, the base 3 is driven to flip by the rotating shaft 2, and then the OLED screen is flipped downward. The lifting seat simultaneously drives the rotating disk 14 and the grinding plate 15 to rise and contact the glass substrate of the OLED screen to perform the grinding operation. Impurities appearing during the grinding process will fall naturally under the action of gravity, avoiding the impurities falling on the OLED screen and affecting the subsequent operations. After the grinding is completed, the lifting seat descends, and the rotating shaft 2 drives the base 3 to flip, so that the glass substrate of the OLED screen faces upward, which is convenient for the subsequent laser lighting stripping process.

[0035] Specifically, Figure 2 , 3 , 4, 6, 7 and 10, in some embodiments, the clamping mechanism includes a plurality of mobile boxes 6 and a pre-pressing plate 7, the plurality of mobile boxes 6 are circumferentially arranged around the fixed disk 4, a guide plate 17 is arranged at the bottom of the mobile box 6, a guide rail 16 is arranged at the bottom of the fixed disk 4 toward its center, the mobile box 6 is slidably connected to the fixed disk 4 through the cooperation of the guide plate 17 and the guide rail 16, a guide disk 18 is rotatably arranged at the bottom of the fixed disk 4, a guide column 20 is arranged on the guide plate 17, an arc-shaped guide groove 19 extending toward its center is arranged on the guide disk 18, and the mobile box 6 is slidably arranged on the guide disk 18 through the guide column 20 and the arc-shaped guide groove 19;

[0036] like Figure 2 and 4 As shown, the pre-compression plate 7 is slidably connected to the moving box 6 , one end of which passes through the side wall of the fixed disk 4 and extends to the top of the fixed disk 4 , and a first spring 21 is arranged between the other end of the pre-compression plate 7 and the moving box 6 .

[0037] The guide plate 18 is rotated. Due to the sliding fit between the guide groove 19 and the guide post 20, and the restriction of the sliding fit between the guide plate 17 and the guide rail 16, the guide post 20 can move along the guide groove 19, and the guide plate 17 moves along the guide rail 16 without rotating together with the guide plate 18, thereby causing the movable box 6 to move toward or away from the center of the fixed plate 4. The movement of the movable box 6 will drive the pre-pressing plate 7 to move together. When moving toward the center of the fixed plate 4, the pre-pressing plate 7 first contacts the side of the OLED screen. The guide plate 18 is continued to be rotated. When the movable box 6 continues to move toward the center of the fixed plate 4, the pre-pressing plate 7 is restricted by the OLED screen and no longer moves, so that the first spring 21 between the movable box 6 and the pre-pressing plate 7 is compressed, and then the pre-pressing plate 7 is pressed against the edge of the OLED screen to achieve effective fixation. Specifically, Figure 1 , 2 , 3, and 4, wherein the number of the mobile boxes 6 is 4, wherein the pre-pressing plate 7 is L-shaped, one end of which extends horizontally toward the fixed disk 4, and passes through the side walls of the mobile box 6 and the fixed disk 4 to slide with the mobile box 6 and the fixed disk 4, and is used to contact the OLED screen, and the other end thereof extends toward the bottom of the fixed disk 4, and a first spring 21 is arranged between the end and the side wall of the mobile box 6 and the fixed disk 4. In order to avoid interference between the pre-pressing plates 7 when they move in the fixed disk 4, two adjacent pre-pressing plates 7 can be arranged at different heights of the side wall of the fixed disk 4. Using the mobile and pre-pressing plates 7 as a clamping mechanism can match the clamping of OLED screens of different sizes.

[0038] Furthermore, in order to ensure that the clamping mechanism can maintain the clamping state after clamping the OLED screen to prevent loosening, as Figure 2 , 4 As shown in 10, in some embodiments, a limiting device is also included, and the limiting device includes a vertical rod 22, a movable disk 25 and a limiting disk 27; the upper end of the vertical rod 22 is arranged in the movable box 6 and is slidably connected to the pre-pressing plate 7, and the other end passes through the clearance hole 51 at the bottom of the movable box 6 and is slidably connected to the dovetail groove 26 on the movable disk 25, a limiting column 29 is arranged at the bottom of the movable disk 25, the limiting disk 27 is arranged on the base 3, and a limiting hole 28 matching the limiting column 29 is arranged on the upper surface thereof, an inclined groove 23 is arranged on the side wall of the movable box 6, and a plug column 24 slidingly matched with the inclined groove 23 is arranged on the vertical rod 22.

[0039] As described above, when moving toward the center of the fixed disk 4, the pre-pressing plate 7 first contacts the side of the OLED screen. When the moving box 6 continues to move toward the center of the fixed disk 4, the pre-pressing plate 7 is restricted by the OLED screen and no longer moves, so that the first spring 21 between the moving box 6 and the pre-pressing plate 7 is compressed. In this process, since the moving box 6 is still moving toward the fixed disk 4, and the pre-pressing plate 7 does not move, since the side wall of the moving box 6 is provided with an inclined groove 23, and the vertical rod 22 is connected to the pre-pressing plate 7 by sliding up and down, the vertical rod 22 moves downward along the pre-pressing plate 7 under the sliding cooperation of the plug column 24 and the inclined groove 23, and then drives the moving disk 25 to move downward, and finally the limiting column 29 on the moving disk 25 is inserted into the limiting hole 28 on the limiting disk 27, thereby forming a limit.

[0040] like Figure 2 , 7 As shown in Figure 10, in some embodiments, in order to facilitate the adjustment of the position of the adjustment plate 5, the adjustment mechanism includes an adjustment shaft 34 and a retaining ring 36, one end of the adjustment shaft 34 is rotatably connected to the adjustment plate 5, and the other end extends to the outside of the base 3, the retaining ring 36 is arranged at the bottom of the fixed disk 4, and a plurality of grooves 37 are arranged in the height direction of the inner wall thereof, and a notch is arranged on the groove 37, and a block 38 cooperating with the groove 37 is arranged at one end of the adjustment shaft 34 close to the adjustment plate 5, and the width of the block 38 is smaller than the width of the notch, and a torsion spring 33 is also arranged between the adjustment plate 5 and the adjustment shaft 34.

[0041] Specific as Figure 2 , 7 As shown in Figure 10, through holes are provided in the central part of the fixed plate 4, the guide plate 18, the movable plate 25, the limit plate 27 and the base 3, and the adjustment shaft 34 passes through the base 3, the limit plate 27, the movable plate 25, the guide plate 18 and the fixed plate 4 from top to bottom in sequence and is rotatably connected with the adjustment plate 5. When the height of the adjustment plate 5 in the fixed plate 4 needs to be adjusted, the adjustment shaft 34 is rotated so that the block 38 is located at the notch of the slot 37, and then the adjustment shaft 34 can move freely up and down, and the adjustment shaft 34 can be moved upward to drive the adjustment plate 5 to move upward, and the block 38 also moves upward to the slot 37 of the corresponding height, and the adjustment shaft 34 can be rotated in the opposite direction or under the action of the reset force of the torsion spring 33, the block 38 can be inserted into the slot 37 of the corresponding height, and then the adjustment plate 5 is fixed and positioned at the corresponding height, and then the depth of the fixed plate 4 is adjusted to match OLED screens of different thicknesses.

[0042] like Figure 2 and 10As shown, in some embodiments, specifically, in order to facilitate the operation of the rotating guide plate 18, it also includes a rotating drum 8, which is coaxially arranged with the adjusting shaft 34 and sleeved on the outside of the adjusting shaft 34. One end of the rotating drum 8 is rotatably arranged at the bottom of the fixed plate 4, and the other end extends to the base 3. The guide plate 18 is sleeved on the outside of the rotating drum 8 and is transmission-connected to the rotating drum 8.

[0043] As shown in the figure, the rotating drum 8 passes through the through holes of the limiting plate 27, the moving plate 25 and the guide plate 18 from bottom to top in sequence and then rotates and is arranged at the bottom of the fixed plate 4, wherein the rotating drum 8 and the guide plate 18 are connected by a transmission, which may be a spline connection, so that the rotation of the rotating drum 8 can drive the rotation of the guide plate 18 without affecting the normal movement of other structures. When the rotating drum 8 is rotated, the guide plate 18 rotates, and the rotation of the guide plate 18 realizes the movement of the above-mentioned clamping mechanism and the limiting device, which is convenient for operation.

[0044] like Figure 2 and 10 As shown, specifically, in some embodiments, a slide cylinder 30 is also included, and the slide cylinder 30 is sleeved on the outside of the rotating cylinder 8. One end of the slide cylinder 30 is fixedly connected to the limit plate 27, and the other end extends to the outside of the base 3. The slide cylinder 30 and the rotating cylinder 8 are connected by a spline, and a second spring 32 is arranged between the slide cylinder 30 and the rotating cylinder 8.

[0045] Under normal conditions, the limit plate 27 is supported and suspended in the base 3 by the second spring 32, and will not deflect under the restriction of the rotating drum 8 and the slide 30. When the vertical rod 22 drives the movable plate 25 to move downward, it contacts and presses the limit plate 27 downward, and when the limit column 29 on the movable plate 25 is aligned with the limit hole 28 on the limit plate 27, the limit plate 27 rises under the action of the second spring 32, so that the limit column 29 and the limit hole 28 are plugged and matched. At this time, the limit plate 27, the rotating drum 8 and the slide 30 are restricted and cannot rotate, forming a limit position. Even under the action of the reaction force of the first spring 21, the limit column 29 and the limit hole 28 will not be separated. When the clamping mechanism needs to release the OLED screen, the slide cylinder 30 is pulled downward to drive the limit plate 27 to move downward, so that the limit column 29 can be separated from the limit hole 28 of the limit plate 27, and then the slide cylinder 30 is rotated, the slide cylinder 30 drives the rotating cylinder 8 to rotate, the rotating cylinder 8 drives the guide plate 18 to rotate, and the guide plate 18 drives the moving box 6 to move away from the center of the fixed plate 4, and the moving plate 25 rises and resets accordingly, so that the clamping mechanism can release the OLED screen. At the same time, the slide cylinder 30 extends to the outside of the base 3 for easy operation.

[0046] Furthermore, if Figure 2 and 10As shown, in some embodiments, for the convenience of operation, a handle 31 is provided at the bottom of the slide cylinder 30, one end of the adjustment shaft 34 passes through the handle 31 and is connected to the pull block 35, one end of the second spring 32 is connected to the rotary cylinder 8, and the other end is connected to the handle 31. The operator only needs to operate the handle 31 and the pull block 35 to realize the above operation, which is convenient to operate.

[0047] like Figure 1 , 2 , 8, 9 and 11, in some embodiments, the power mechanism includes a first motor 43, a reciprocating screw 40, a slide rail 39 and a slider 9, the first motor 43 is installed on the base 1, and its output end is transmission-connected to the reciprocating screw 40, the slider 9 is threadedly connected to the reciprocating screw 40, the slide rail 39 is slidingly connected to the slider 9 and is parallel to the reciprocating screw 40, the slider 9 is provided with a guide column 12 facing the rotating shaft 2, the rotating shaft 2 is provided with a guide column 12 matched with a guide groove, and the guide groove includes a spiral groove 10 and a straight groove 11 that are connected.

[0048] The first motor 43 drives the reciprocating screw 40 to rotate. The slider 9 is restricted by the slide rail 39, and the slider 9 reciprocates axially on the reciprocating screw 40. At the same time, when the guide column 12 is located in the spiral groove 10, it can drive the rotating shaft 2 to rotate, thereby driving the base 3 to flip. When it is located in the straight groove 11, the base 3 remains in a flipped downward state and does not rotate, thereby facilitating the grinding operation. After the grinding is completed, the reciprocating screw 40 continues to rotate, the guide column 12 moves into the spiral groove 10 again, and the base 3 flips and resets to an upward state, and the cycle continues. A fixed shell 42 can be set outside the first motor 43 to protect the first motor 43.

[0049] like Figure 1 , 2 , 8 and 9, specifically, in some embodiments, the lifting seat includes a control part 46 and a mounting part 13, the turntable 14 is set on the mounting part 13 through the second motor 50, the control part 46 extends upward from the mounting part 13 toward the reciprocating screw 40, the slider 9 is provided with a control column 49, the control part 46 is provided with a control groove, the control groove includes a transverse groove 48 and a horizontal groove 47, and the transverse groove 48 and the horizontal groove 47 are connected through the oblique groove 41.

[0050] The lifting seat is also driven by a power mechanism, which is the same as the power mechanism of the base 3, reducing the number of power mechanisms. During the reciprocating motion of the slider 9 on the reciprocating screw 40, the control column 49 on the slider 9 can realize the lifting and lowering of the lifting seat through the control groove. Specifically, when the control column 49 is located at the horizontal groove 48, the lifting seat does not lift, and when the horizontal groove 48 enters the oblique groove 41, the lifting seat rises. When the control column 49 is located at the horizontal groove 47, the lifting seat remains in the highest position. At this time, the grinding plate 15 contacts the glass substrate, and the grinding plate 15 rotates to grind the glass substrate. After the grinding is completed, the guide column 12 is still located in the straight groove 11, that is, the base 3 does not rotate. The control column 49 first reaches the oblique groove 41 from the horizontal groove 47 and then drives the lifting seat to descend first. After descending to a certain height, the guide column 12 moves into the spiral groove 10 and then starts to drive the base 3 to rotate, so as to avoid interference between the rotation of the base 3 and the lifting of the lifting seat. As shown in the figure, a connecting plate 45 is provided between the control part 46 and the mounting part 13 to achieve the connection between the two.

[0051] Specifically, in some embodiments, the base 1 includes a fixed plate at the bottom and a mounting plate vertically arranged on the fixed part. There are two mounting plates. The two ends of the rotating shaft 2 and the reciprocating screw 40 are rotatably arranged on the two mounting plates respectively. A clearance groove 44 is provided on the mounting plate close to the turntable 14. One end of the mounting part 13 passes through the clearance groove 44 and is connected to the control part 46. The two mounting plates can effectively realize the installation and support of the fixed rotating shaft 2 and the reciprocating screw 40. In addition, the design of the clearance groove 44 can also meet the lifting and lowering of the lifting seat. This structural design can also isolate the power mechanism from the base 3 and the turntable 14, which is more neat and safe to operate. Specifically, the connecting plate 45 is slidably arranged in the clearance groove 44 to improve the stability of lifting.
