Description

Technical Field

[0001] The present application relates to the technical field of display panels, and in particular to a flexible screen support device and a pressing device. Background Art

[0002] COP packaging (Chip On Pi) is a screen packaging process that greatly increases the screen-to-body ratio by bending all the cables and IC chips (Integrated Circuit Chip) to the bottom of the screen, making the phone screen look more integrated and borderless.

[0003] Since the wiring thickness of each part of the binding area of ​​the screen is different, during the process of bonding the screen to the support film, small bubbles exist between the area with thinner wiring thickness in the binding area of ​​the screen and the support film. In the subsequent process of binding the IC chip in the binding area, the above-mentioned small bubbles will expand and become larger after being heated, and it is easy to form directly visible bubbles, which affects the pass rate of the display panel reliability test (RA, Reliability Test).

[0049] The features and exemplary embodiments of various aspects of the present application will be described in detail below. For the purpose of making the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "including..." do not exclude the existence of additional identical elements in the process, method, article or device including the said elements.

[0051] Currently, through Chip On Pi packaging, the flexible cable and the IC chip (Integrated Circuit Chip) can be bent entirely under the screen, thus greatly increasing the screen-to-body ratio and making the mobile phone screen look more integrated and borderless.

[0052] It has been found through research that due to the different wire thicknesses in each part of the bonding area of the screen body, there are small air bubbles between the area with a thinner wire thickness in the bonding area of the screen body and the support film during the process of attaching the screen body to the support film. During the subsequent process of bonding the IC chip to the bonding area, the above-mentioned small air bubbles will expand when heated, easily forming directly visible air bubbles, which affects the passing rate of the reliability test (RA, Reliability Test) of the display panel.

[0053] To solve the problems of the prior art, the embodiments of the present application provide a flexible screen body support device and a pressing device. The following will be introduced in detail with reference to the accompanying drawings.

[0054] Figure 1 It is a schematic structural diagram of the flexible screen body support device and the pressing device provided by some embodiments of the present application.

[0055] Please refer to Figure 1 , the embodiments of the present application provide a flexible screen body support device, including a bearing unit 3 and a lifting unit 4. Among them, the bearing unit 3 includes at least one supporting part, and each supporting part can support a screen body component 2. Among them, the screen body component 2 includes a screen body 21 and a support film 22. Each supporting part includes a plurality of ejector pins 31 arranged in an array, and adjacent supporting parts are independently distributed. The ejector pins 31 are arranged to be liftable along the first direction X. The lifting unit 4 is connected to the bearing unit 3 and is used to provide a lifting force along the first direction X to the ejector pins 31. The lifting unit 4 is used to drive some of the ejector pins 31 to extend along the first direction X towards the screen body component 2 to press the corresponding support film 22 against the area with a thinner wire thickness in the bonding area of the screen body 21, thereby reducing the risk of air bubbles remaining between the support film 22 and the screen body, and improving the passing rate of the reliability test of the display panel; in addition, when there are multiple supporting parts, multiple screen body components 2 can be supported simultaneously to improve the overall production efficiency of the flexible screen body.

[0056] The flexible screen body can be applied to devices with display functions such as televisions, mobile phones, computers, laptops, tablets, in-vehicle computers, personal digital assistants (Personal Digital Assistant, PDA), etc. The present application does not limit the display devices with the above flexible screen bodies.

[0057] Figure 2 It is a schematic structural diagram of the ejector pin 31 provided by some embodiments of the present application.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, among the multiple ejector pins 31 included in each supporting portion, two adjacent ejector pins 31 are arranged in contact with each other, and the ejector pin 31 includes a first end face 3111. The first end faces 3111 of the multiple ejector pins 31 are used to synchronously support the screen assembly 2, which can avoid the situation where the first end faces 3111 corresponding to the adjacent ejector pins 31 cannot jointly press the support film 22 to the area where the wiring thickness of the binding area of ​​the screen 21 is thinner due to the large spacing between the adjacent ejector pins 31.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the length of the ejector pin 31 along the second direction Y and the length along the third direction Z are both less than or equal to the first preset value, and the second direction Y intersects with the third direction Z and is perpendicular to the first direction X. The width of the thinner wiring thickness area of ​​the screen body 21 binding area is generally 1mm-2mm. By limiting the first preset value, it is possible to avoid the ejector pin 31 being too large to press the support film 22 against the thinner wiring thickness area of ​​the screen body 21 binding area.

[0060] In some embodiments, the first preset value is between 0.3 mm and 0.6 mm. When the first preset value is less than 0.3 mm, the rigidity of the ejector pin 31 is poor and it is easy to bend; when the first preset value is greater than 0.6 mm, along the width direction of the thinner wiring thickness area of ​​the binding area of ​​the screen body 21, the first end faces 3111 of adjacent ejector pins 31 are difficult to jointly press the support film 22 to the thinner wiring thickness area of ​​the binding area of ​​the screen body 21. Optionally, the first preset value can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm or 0.6 mm.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, the ejector pin 31 includes a rigid section 312 extending along the first direction X, one end of the rigid section 312 is fixedly connected to the buffer section 311, and the first end surface 3111 is located on the side of the buffer section 311 facing away from the rigid section 312. It can be understood that the rigidity of the rigid section 312 is greater than the rigidity of the buffer section 311. By providing the buffer section 311, the edge of the first end surface 3111 can be prevented from scratching the support film 22 during the process of the first end surface 3111 supporting the support film 22; by providing the rigid section 312, the ejector pin 31 can be prevented from being greatly deformed as a whole during the process of the first end surface 3111 supporting the support film 22.

[0062] like Figure 1 and Figure 2As shown, in some embodiments, along the first direction X, the projection of the buffer section 311 is within the projection range of the rigid section 312. During the process of the first end face 3111 supporting the support film 22, the gap between adjacent buffer sections 311 allows the buffer section 311 to deform along the second direction Y and the third direction Z.

[0063] As Figure 1 and Figure 2 shown, in some embodiments, the length of the buffer section 311 along the second direction Y and the length along the third direction Z are both greater than or equal to the height of the buffer section 311 along the first direction X. During the process of the first end face 3111 supporting the support film 22, large deformations of the buffer section 311 along the second direction Y and the third direction Z can be avoided, thereby reducing the risk of large deformations of the entire ejector pin 31 caused by the extrusion of adjacent buffer sections 311 along the second direction Y and / or the third direction Z.

[0064] In some embodiments, the cross-section of the rigid section 312 is rectangular, enabling the ejector pins 31 to be closely arranged.

[0065] In some embodiments, the material of the buffer section 311 is silicone, which has good elasticity, tear resistance, and aging resistance. During the process of the first end face 3111 supporting the support film 22, the edge of the first end face 3111 can be prevented from scratching the support film 22.

[0066] Figure 3 is Figure 1 a top view structural schematic diagram of the loading unit 3 in

[0067] As Figure 1 and Figure 3 shown, in some embodiments, the loading unit 3 further includes a carrier 32. The carrier 32 includes a first frame 321 and a clamping assembly 322. The first frame 321 includes an enclosing area, which is arranged corresponding to the top supporting parts one by one. A plurality of ejector pins 31 included in each top supporting part are installed in the corresponding enclosing area. Specifically, in this embodiment, one top supporting part and one enclosing area are provided. The clamping assembly 322 is installed on the first frame 321 and is used to adjust the length of the enclosing area along the second direction Y and / or the length along the third direction Z. Specifically, in this embodiment, the clamping assembly 322 is used to adjust the length of the enclosing area along the second direction Y and the length along the third direction Z. When the clamping assembly 322 is in the first state, the length of the enclosing area along the second direction Y and the length along the third direction Z are both at the minimum value, and the plurality of ejector pins 31 are in close contact, enabling the ejector pins 31 to stably support the screen assembly 2. When the clamping assembly 322 is in the second state, the length of the enclosing area along the second direction Y and the length along the third direction Z are both at the maximum value, and there is a small gap between the ejector pins 31, facilitating the lifting unit 4 to adjust the height of some ejector pins 31 along the first direction X.

[0068] As Figure 1 and Figure 3 shown, in some embodiments, the clamping assembly 322 includes a first adjusting member, the first adjusting member is installed on at least one side of the enclosure area along the second direction Y, the first adjusting member includes a first push plate 3221 slidably connected to the first frame 321 and a first driver 3222 for driving the first push plate 3221 to move along the second direction Y. It can be understood that the first driver 3222 can be an oil cylinder or other components capable of driving the first push plate 3221 to perform a linear motion. Specifically, in this embodiment, the first adjusting member is installed on one side of the enclosure area along the second direction Y; in other embodiments, the first adjusting members can also be installed on both sides of the enclosure area along the second direction Y respectively to adjust the length of the enclosure area along the second direction Y.

[0069] As Figure 1 and Figure 3 shown, in some embodiments, at least one first limiting block 323 is installed on the first frame 321, the first limiting block 323 is located on the side of the first push plate 3221 facing away from the ejector pin 31, and in the state where the first push plate 3221 abuts against the ejector pin 31, the distance between the first push plate 3221 and the first limiting block 323 is below a second preset value. By defining the second preset value, it is possible to avoid the position of the ejector pin 31 being disordered due to the excessive length of the enclosure area along the second direction Y.

[0070] In some embodiments, half of the length of the ejector pin 31 along the second direction Y is greater than or equal to the second preset value. When the second preset value is greater than half of the length of the ejector pin 31 along the second direction Y, the length of the enclosure area along the second direction Y is too large, which easily leads to the position of the ejector pin 31 being disordered.

[0071] As Figure 1 and Figure 3 shown, in some embodiments, the clamping assembly 322 includes a second adjusting member, the second adjusting member is installed on at least one side of the enclosure area along the third direction Z, the second adjusting member includes a second push plate 3223 slidably connected to the first frame 321 and a second driver 3224 for driving the second push plate 3223 to move along the third direction Z. It can be understood that the second driver 3224 can be an oil cylinder or other components capable of driving the second push plate 3223 to perform a linear motion. Specifically, in this embodiment, the second adjusting member is installed on one side of the enclosure area along the third direction Z; in other embodiments, the second adjusting members can also be installed on both sides of the enclosure area along the third direction Z respectively to adjust the length of the enclosure area along the third direction Z.

[0072] As Figure 1 and Figure 3As shown, in some embodiments, at least one second limiting block 324 is installed on the first frame body 321. The second limiting block 324 is located on the side of the second push plate 3223 facing away from the ejector pin 31. When the second push plate 3223 abuts against the ejector pin 31, the distance between the second push plate 3223 and the second limiting block 324 is below a third preset value. By defining the third preset value, it is possible to avoid the position of the ejector pin 31 being disordered due to the excessive length of the enclosure area along the third direction Z.

[0073] In some embodiments, half of the length of the ejector pin 31 along the third direction Z is greater than or equal to the third preset value. When the third preset value is greater than half of the length of the ejector pin 31 along the third direction Z, the length of the enclosure area along the third direction Z is too large, which easily leads to the position of the ejector pin 31 being disordered.

[0074] Figure 4 For Figure 1 the top view structural schematic diagram of the second frame body 41 and the lifting block 42 in the present application; Figure 5 is the structural schematic diagram of the lifting unit 4 provided in some other embodiments of the present application; Figure 6 For Figure 5 the top view structural schematic diagram.

[0075] As Figure 1 , Figure 2 , and Figures 4 to 6 As shown in, and, in some embodiments, the ejector pin 31 includes a second end face 3121. Along the first direction X, the second end face 3121 and the first end face 3111 are respectively located at both ends of the ejector pin 31. The lifting unit 4 includes a second frame body 41, a lifting block 42, and a third driver 43. Among them, the second frame body 41 includes a top wall 411, and the top wall 411 includes a first wall surface 4111 facing the bearing unit 3; the lifting block 42 includes a second wall surface 421 facing the bearing unit 3. At least one lifting block 42 is installed on the top wall 411 in a liftable manner. The first wall surface 4111 and the second wall surface 421 are used to synchronously support a plurality of second end faces 3121; the third driver 43 is installed between the second frame body 41 and the lifting block 42 to drive the lifting block 42 to move relative to the top wall 411 along the first direction X. It can be understood that the second frame body 41 further includes a seat body for installing the top wall 411, and the third driver 43 is installed between the seat body and the lifting block 42. The third driver 43 can be a component such as an oil cylinder that can drive the lifting block 42 to perform linear motion. By driving the lifting block 42 to move along the first direction X, the third driver 43 can indirectly control the corresponding ejector pin 31 to perform a lifting motion along the first direction X, so that the corresponding ejector pin 31 presses the support film 22 against the area with a thinner wiring thickness in the bonding area of the screen body 21, thereby reducing the risk of air bubbles remaining between the support film 22 and the screen body.

[0076] In some embodiments, the portion of the ejector pin 31 near the second end face 3121, the top wall 411, and the lifting block 42 are all made of magnetic materials, so that there is an attractive force between the top wall 411 and the ejector pin 31, and between the lifting block 42 and the ejector pin 31. That is, the second end face 3121 can tightly abut against the first wall surface 4111 or the second wall surface 421, thereby enabling the lifting unit 4 to more precisely control the height of the first end face 3111.

[0077] As Figure 1 and Figure 4 shown, in some embodiments, multiple lifting blocks 42 are successively distributed along the second direction Y. The area with a relatively thin wiring thickness in the bonding area of the screen body 21 is generally strip-shaped. By arranging multiple successively distributed lifting blocks 42, the number of ejector pins 31 to be lifted can be adjusted as needed to adapt to the length of the area with a relatively thin wiring thickness in the bonding area of the screen body 21, making the lifting unit 4 highly versatile. As Figure 5 and Figure 6 shown, in some other embodiments, only one lifting block 42 can also be provided to lift the corresponding ejector pin 31 for the same type of screen body assembly 2.

[0078] In some embodiments, the top wall 411, the lifting block 42, and the third driver 43 can all be detachably installed on the second frame body 41, and the top wall 411, the lifting block 42, and the third driver 43 can be replaced as needed to adapt to different screen body assemblies 2.

[0079] As Figure 1 and Figure 4 shown, in some embodiments, the lifting unit 4 includes multiple groups of lifting blocks 42. The multiple groups of lifting blocks 42 are spaced along the third direction Z. The number of lifting blocks 42 included in each group is more than one, and the number of ejector pins 31 to be lifted can be adjusted as needed, making the lifting unit 4 highly versatile.

[0080] As Figure 1 and Figure 4 shown, in some embodiments, each group of lifting blocks 42 includes multiple lifting blocks 42 successively distributed along the second direction Y. The width of each lifting block 42 included in each group of lifting blocks 42 along the third direction Z is the same, and along the third direction Z, the widths of the lifting blocks 42 gradually increase, so that different groups of lifting blocks 42 can adapt to areas with different widths of the wiring thickness in the bonding area of the screen body 21, making the lifting unit 4 highly versatile.

[0081] As Figure 1As shown, in some embodiments, the lifting unit 4 further includes an alignment component, which includes a third frame 46, a fourth driver 45, and a fifth driver 44. The second frame 41 is successively installed on the third frame 46 through the fifth driver 44 and the fourth driver 45. The fifth driver 44 is used to drive the second frame 41 to move along the first direction X, and the fourth driver 45 is used to drive the second frame 41 to move along the second direction Y and / or the third direction Z. Specifically, in this embodiment, the fourth driver 45 is indirectly connected to the second frame 41 through the fifth driver 44. It can be understood that the fifth driver 44 can be an oil cylinder or other components capable of driving the second frame 41 to perform linear motion, and the fourth driver 45 can be a conveyor belt, an oil cylinder, a linear motion module, or other components capable of driving the fifth driver 44 to move in a plane perpendicular to the first direction X. The alignment component is used to drive the second frame 41 to move so that the first wall surface 4111 and the second wall surface 421 can accurately abut against the ejector pins 31 in the corresponding area.

[0082] As Figure 1 and Figure 3 shown, in some embodiments, a detection element 33 is installed on the side of the bearing unit 3 facing away from the second end face 3121, which is used to scan the surface to be supported of the screen body assembly 2 facing the bearing unit 3 to collect the dimensions of the concave and convex areas of the surface to be supported.
