The application provides a pressure maintaining jig, which comprises but is not limited to the following embodiments and the combination of the following embodiments.
In an embodiment, as shown in fig. 1, the pressure maintaining fixture 00 is used for maintaining a pressure of a display panel, so that the display panel has a preset shape, and the pressure maintaining fixture 00 includes: a main body 10, the main body 10 having an accommodating space 101 and an opening 102 at one side of the accommodating space 101; the adjusting blocks 20 are located in the accommodating space 101, the adjusting blocks 20 are parallel to each other, and when the pressure maintaining jig 00 is used for maintaining the pressure of the display panel, as shown in fig. 2, the adjusting blocks 20 protrude toward the opening 102 to form a protruding portion 201, and the protruding shape of the protruding portion 201 is matched with the preset shape.
The display panel can be a liquid crystal display panel, and when the display panel is used as the liquid crystal display panel, the display panel further comprises a backlight plate, a rubber frame, a display module and a cover plate, wherein the backlight plate is connected with the display module through the rubber frame. The pressure maintaining jig is used for maintaining pressure of the display panel, and can be understood that the pressure maintaining jig acts on the backlight plate or the cover plate, so that contact surfaces of adjacent two of the backlight plate, the rubber frame, the display module and the cover plate can be attached.
It will be appreciated that, as shown in fig. 1-2, only a rectangular parallelepiped space is taken as the accommodating space 101 of the main body 10, the opening 102 is located on the lower surface of the main body 10, and the plurality of adjusting blocks 20 are arranged in parallel along the direction of the longest side of the accommodating space 101. In fact, the accommodating space 101 of the main body 10 may be a sphere space, a cylinder space, or another three-dimensional space, the opening 102 may be located at any side of the main body 10, and the plurality of adjusting blocks 20 may be arranged in parallel along any direction non-perpendicular to the opening 102, so long as it is satisfied that the plurality of adjusting blocks 20 can all move through the opening 102 at the same time.
Specifically, for example, the preset shape may be a preset shape of the display panel, and the relative positions of the plurality of adjusting blocks 20 and the opening 102 may be adjusted according to parameters such as curvature and length of the preset shape, so that the shape of the side of the formed protruding portion 201 away from the accommodating space 101 matches the preset shape; for another example, the backlight plate or other structures in the display panel may have the predetermined shape, and a side of the plurality of adjustment blocks 20 away from the receiving space 101 may be brought into contact with the backlight plate or other structures in the display panel having the predetermined shape and pressure is applied such that the shape of the side of the formed protrusion 201 away from the receiving space 101 matches the predetermined shape.
It should be noted that it is sufficient here that each of the plurality of adjustment blocks 20 protrudes from the opening 102, and that the shape of the side of the protruding portion 201 away from the accommodation space 101 matches the preset shape, i.e., there is no limitation in the distance between each of the plurality of adjustment blocks 20 and the opening 102, but there is a limitation in the relative positions of the plurality of adjustment blocks 20.
In an embodiment, as shown in fig. 3, when the preset shape is a plane, the shape of the protrusion 201 formed by the plurality of adjustment blocks 20 on the side away from the accommodating space 101 is a plane, so that the display panel may have the shape of the plane; as shown in fig. 4, when the preset shape is a concave curved surface, a shape of a side of the protrusion 201 formed by the plurality of adjustment blocks 20 away from the accommodating space 101 is a convex curved surface complementary to the concave curved surface, so that the display panel may have the shape of the concave curved surface; as shown in fig. 5, when the preset shape is a first "S" shaped curved surface, the shape of the protrusion 201 formed by the plurality of adjustment blocks 20 on the side away from the accommodating space 101 is a second "S" shaped curved surface complementary to the first "S" shaped curved surface, so that the display panel may have the shape of the first "S" shaped curved surface. Thus, for different requirements of the preset shape, the protrusion 201 having a shape matching the preset shape may be obtained by adjusting the relative positions of the plurality of adjustment blocks 20. Therefore, the present embodiment does not need to design the pressure maintaining jig with different curvatures according to different requirements of the preset shape, and does not need to determine whether to discard the corresponding pressure maintaining jig according to the life cycle of the display panel, so that the present embodiment reduces the management difficulty and the manufacturing cost of the pressure maintaining jig.
It can be appreciated that, since the plurality of adjusting blocks 20 parallel to each other act on the display panel together, on the premise of ensuring that the plurality of adjusting blocks 20 can be adjusted up and down, the distance between two adjacent adjusting blocks 20 in the plurality of adjusting blocks 20 can be as small as possible, so that the side, far away from the accommodating space 101, of the protruding portion 201 formed by the plurality of adjusting blocks 20 can be formed into a continuous plane or curved surface, so as to reduce errors with the preset shape, and improve accuracy of the shape formed by pressure maintaining on the display panel.
It will be appreciated that since the main body 10 needs to maintain a fixed shape for a long period of time to maintain the accommodating space 101, and the adjustment block 20 needs to be adjusted for a long period of time to form the corresponding boss 201, the hardness of both the main body 10 and the adjustment block 20 is relatively high, for example, the main body 10 and the adjustment block 20 may be made of a metal material.
In an embodiment, as shown in fig. 6, the pressure maintaining fixture 00 further includes: the plurality of rollers 30, the plurality of rollers 30 and the plurality of adjusting blocks 20 are in one-to-one correspondence, the plurality of rollers 30 are arranged in parallel, each roller 30 of the plurality of rollers 30 is respectively arranged on one side of the protrusion 201 of the corresponding adjusting block 20, and the plurality of rollers 30 are used for adjusting the positions of the plurality of adjusting blocks 20 on the display panel.
It will be appreciated that, due to the greater hardness of the adjustment block 20, if directly contacted and acted on the display panel, is extremely prone to scratching or even crushing the display panel. It can be appreciated that a roller 30 is disposed on one side of each adjusting block 20 acting on the display panel, the outer surface of the roller 30 is a smooth curved surface, the roller 30 moves on the display panel and is in rolling friction, and sliding friction is performed on the display panel relative to the adjusting blocks 20, so that the friction between the pressure maintaining jig 00 and the display panel can be reduced, and the efficiency of the pressure maintaining jig 00 for maintaining the pressure of the display panel can be improved.
Further, the plurality of rollers 30 may be made of rubber. Because rubber is a high-elasticity polymer material with reversible deformation, the high-elasticity polymer material is elastic at room temperature, can generate larger deformation under the action of small external force, and can recover after the external force is removed, when the pressure maintaining jig 00 applies acting force to the display panel, the rollers 30 can play a role in buffering, so that the display panel is prevented from being damaged by the action force at one moment, and the reliability of the display panel is improved when the pressure maintaining jig 00 maintains the pressure. It will be appreciated that, although the plurality of rollers 30 deform during the process of acting on the display panel, when each roller 30 deforms, the effect of the deformation on the overall shape of the display panel is counteracted, so that the display panel can substantially form the predetermined shape; and when the rollers 30 are separated from the display panel, the original shape can be recovered, or the abrasion degree of the rollers 30 after multiple uses is equivalent, and the rollers will not generate differentiation on other display panels in the later stage.
In one embodiment, the projection of each roller 30 onto the corresponding adjustment block 20 is within the boundaries of the corresponding adjustment block 20. It can be appreciated that when the plurality of rollers 30 drive the plurality of adjusting blocks 20 to move on the display panel, if the projection of each roller 30 on the corresponding adjusting block 20 is located within the boundary of the corresponding adjusting block 20, that is, a preset distance is provided between two adjacent rollers 30, so that the rollers 30 are prevented from being unable to normally operate, thus reducing the risk of failure of the two adjacent rollers 30 and improving the efficiency of the pressure maintaining jig 00 for maintaining the pressure of the display panel.
In one embodiment, as shown in fig. 7, each roller 30 may include an axle 301 and a wheel 302, the axle 301 extending through the wheel 302 in a direction in which the wheel 302 extends, the wheel 302 rotating about the axle 301 under rotation of the corresponding axle 301. Further, two connection ends 202 are disposed at one side of the adjusting block 20 near the corresponding roller 30, the two connection ends 202 are disposed at the left and right ends of the adjusting block 20, respectively, and the two connection ends 202 are used for connecting the roller 30 to the adjusting block 20. Specifically, the left and right ends of the adjusting block 20 near to one side of the corresponding roller 30 are respectively protruded to form two corresponding connecting blocks 2021, each connecting block 2021 is provided with a through hole 2022, the two through holes 2022 respectively penetrate through the two connecting blocks 2021 along the extending direction of the wheel 302, the wheel 302 is located between the two corresponding connecting ends 202, and the two shafts 301 protruding from the left and right ends of the wheel 302 respectively penetrate through the two corresponding through holes 2022, so as to fix the roller 30 below the corresponding adjusting block 20. Of course, the roller 30 may be fixed below the corresponding adjusting block 20 in other manners, for example, the two connecting ends 202 may include two brackets protruding from the left and right sides of the adjusting block 20, and the two brackets may be integrally formed with two sides of the shaft 301 of the corresponding roller 30 to reduce the risk of separating the connecting ends 202 from the shaft 301, and the connection manner of the roller 30 and the corresponding adjusting block 20 is not limited herein.
In an embodiment, as shown in fig. 8, the pressure maintaining fixture 00 further includes: a first fixing block 40, wherein the first fixing block 40 is arranged on one side of the main body 10; a second fixing block 50, the second fixing block 50 being provided on the opposite side of the main body 10 to the first fixing block 40; when the plurality of adjustment blocks 20 protrude toward the opening 102 to form the protruding portion 201, the first fixing block 40 and the second fixing block 50 are used to approach the body 10 to clamp the plurality of adjustment blocks 20 to fix the positions of the plurality of adjustment blocks 20.
In one embodiment, the first fixing block 40 and the second fixing block 50 are parallel to the extending direction of the plurality of adjusting blocks 20.
Specifically, as shown in fig. 8, when the accommodating space 101 of the main body 10 is rectangular, and the plurality of adjusting blocks 20 are arranged in parallel along the direction of the longest side of the accommodating space 101, it is known from the above that "the first fixing block 40 and the second fixing block 50 are both parallel to the direction in which the plurality of adjusting blocks 20 extend" and "the second fixing block 50 is provided on the opposite side of the main body 10 from the first fixing block 40", that the first fixing block 40 and the second fixing block 50 are provided on the side of the main body 10 excluding the opening 102 and being parallel to the direction in which the plurality of adjusting blocks 20 extend.
