Description

Technical Field

[0001] The present invention relates to the technical field of screen pasting and pressure-maintaining tooling, and in particular to a universal screen pasting and pressure-maintaining tooling. Background Art

[0002] As customers require displays to be designed with narrow black borders, the structural area used to bond the panel and the screen is getting smaller and smaller. The traditional solution of using double-sided tape can no longer meet the bonding strength requirements. Glue has better bonding strength than tape, which is 5 to 10 times that of tape.

[0003] Using glue to bond the panel and screen requires a glue-dispensing screen-sticking line. In order to ensure the consistency of the gap and uniformity of the bonding shape between the panel and the screen, corresponding glue-dispensing screen-sticking tooling (hereinafter referred to as screen-sticking tooling) is required, which is used for pressure-maintaining and fixing.

[0004] like Figure 1 As shown, the traditional customized screen-mounting tooling and pressure-holding tooling applications are mainly composed of existing screen-mounting tooling (1), existing panels (2), existing glue (3), existing screens (4), and existing pressure-holding tooling (5).

[0005] like Figure 2 As shown, the structure of the existing screen-mounting tool (1) mainly includes an existing screen-mounting tool body (101), an existing support part (102), an existing positioning screen-pressing tool column (103), and an existing groove structure (104). Among them, the existing support part (102) and the existing groove structure (104) are customized according to the existing panel (2).

[0006] like Figure 3 As shown, the structure of the existing pressure-maintaining tooling (5) mainly includes an existing pressure-maintaining tooling cover (501); an existing positioning hole (502) for positioning with the positioning column of the screen-attaching tooling; and an existing pressure-maintaining protrusion structure (503) which is customized according to the shape of the existing screen (4).

[0007] like Figure 4 The process flow chart of dispensing, screen pasting, and pressure-holding curing is shown below:

[0008] Pretreatment: First, the existing panel (2) is cleaned.

[0009] Process 1: a glue dispensing process, in which the existing panel (2) is placed on the existing screen-mounting tooling (1), glue is applied to the panel bonding area using a glue dispensing device, and then the glue-coated existing panel (2) and the existing screen-mounting tooling (1) are transferred together to the screen-mounting process;

[0010] Process 2: Screen pasting process, using screen pasting equipment to absorb the existing screen (4), then using a camera to shoot the existing panel (2) and the existing screen (4) to capture the alignment contour or identification points, pasting the existing screen (4) onto the existing panel (2), and then transferring the product with the existing screen (4) pasted and the existing screen pasting tooling (1) to the pressure holding and curing stage.

[0011] Process 3: Pressure-holding and curing process, placing the existing pressure-holding tooling (5) on the product surface and guiding it to the existing screen-attaching tooling (1) for pressure-holding; since the glue is initially in a flowable state with a certain viscosity, it takes a certain amount of time to cure. The curing time depends on the type of glue and the external environmental conditions. Two-component silicone glue with a curing time of about 30 minutes is often used on car screens. Since the curing time of 30 minutes is much longer than the 60-second production cycle of the glue-dispensing and screen-attaching processes, in order to ensure the continuous production of the glue-dispensing and screen-attaching production line, it is necessary to produce multiple sets of screen-attaching and pressure-holding tooling. In the case where the screen is relatively long and the screen-attaching and pressure-holding tooling are also relatively long, in order to save the length of the glue-dispensing and screen-attaching production line, after the screen is placed on the pressure-holding tooling, it will be rotated 90 degrees and placed vertically for pressure-holding.

[0012] The most important and critical technical issues:

[0013] 1. Screen pasting tooling and pressure holding tooling are all customized, and the number of customizations for each project is large. The cost of customized tooling continues to increase with the increase in the number of projects, the space for tooling storage continues to increase, and the management of tooling becomes more and more difficult.

[0014] 2. When the production of one project is completed and the next project is moved on, it takes a long time to dismantle the tooling of the previous project and move the tooling of the next project. In addition, the tooling is relatively heavy, and the intensity of moving the tooling is high. Summary of the invention

[0015] The purpose of the present invention is to provide a universal screen pasting and pressure maintaining tooling to solve the technical problems mentioned in the above background technology.

[0025] Furthermore, the pressure-maintaining tooling is made of bakelite material, and the bottoms of the first pressing block and the second pressing block are respectively pasted with a first foam and a second foam with soft high friction.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, but this does not constitute a limitation on the protection scope of the present invention.

[0044] In the present invention, for a clearer description, the following explanation is made: the observer faces the attached Figure 5 For observation, the left side of the observer is set as left, the right side of the observer is set as right, the front of the observer is set as front, the back of the observer is set as back, the top of the observer is set as top, and the bottom of the observer is set as bottom.

In addition, the terms "first", "second", "third", and "fourth" are only used for the purpose of clarity or simplification of description, and cannot be understood as indicating or implying relative importance or quantity.

[0045] See also Figures 5 to 15 The present embodiment provides a universal screen-mounting and pressure-maintaining tool, including a screen-mounting tool and a pressure-maintaining tool 60. The screen-mounting tool includes a screen-mounting tool body 10 and a screen-mounting tool support 20, that is, the screen-mounting tool is split; the pressure-maintaining tool 60 includes a plurality of pressure blocks (or counterweight blocks). Note: The original scheme of the pressure-maintaining tool is an integrated type, and is positioned with the screen-mounting tool, while the innovative pressure-maintaining tool is changed into a split type from the perspective of functional analysis, and is made into a plurality of universal pressure-maintaining pressure blocks (counterweight blocks), so that the pressure-maintaining tool is not customized due to the change of the screen shape, thereby solving the above-mentioned pain point problem; the screen-mounting tool body 1 0 includes a main body base 11 and a groove portion 14. The groove portion 14 is arranged on the main body base 11, and the opening of the groove portion 14 faces upward. The groove portion 14 is used to accommodate a screen pasting tooling support 20; the screen pasting tooling support 20 includes a supporting bottom plate 21, a limiting support block 22, and a standard support block 25. A notch 211 is provided in the middle of the supporting bottom plate 21. The limiting support block 22 and the standard support block 25 are arranged at the top edge of the supporting bottom plate 21. The limiting support block 22 is used to limit the shape of the panel 30 and provide a supporting position at the same time. The standard support block 25 is used to support the panel 30. Function: (1) When the panel structure is greatly different, it can be quickly replaced by adjusting the entire screen-mounting tooling support. The replaced screen-mounting tooling support can adapt to the changed structure of the panel, and the screen-mounting tooling body does not need to be changed, thereby reducing the time for tooling replacement, improving production efficiency, and reducing manufacturing costs; (2) By making the pressure-holding tooling into a number of universal pressure-holding blocks (counterweight blocks), it is not necessary to customize the pressure-holding tooling due to changes in the screen shape; (3) From the above, it can be seen that universal screen-mounting and pressure-holding tooling can save tooling costs, and screen-mounting tooling and pressure-holding tooling can be applied to the panel structures of different projects to achieve universalization. It should be noted that: from the perspective of functional analysis, the function of the screen-mounting tooling is to bond the panel 30 and the screen 50 together with glue 40. In order to apply the glue to the panel according to the specified trajectory, the screen-mounting tooling is required to ensure its position. The function of the pressure-holding tooling is to ensure the fitting gap between the panel and the screen. Due to the large size of the panel and the large deformation, pressure needs to be applied to the screen surface to overcome the deformation, so a pressure-holding tooling is required.

[0046] Specifically, a plurality of limiting support blocks 22 are distributed at the four corners of the top of the supporting bottom plate 21 and the center of the two long sides. The top of the limiting support block 22 is provided with an inclined surface 221 facing upward and inward. The inclined surface 221 is used to limit the shape of the panel 30 and provide a supporting part at the same time. Function: Through the design of the limiting support block, the panel shape can be better limited and the edge of the panel can be supported.

[0047] Specifically, a plurality of standard support blocks 25 are distributed around the edges of the top of the support base plate 21, and their function is to enable the standard support blocks to better cooperate with the limit support blocks to support the panel. The top of the standard support block 25 is polygonal, and the standard support block 25 can realize its own position rotation. Preferably, the standard support block can realize its own position rotation of 360°, in order to realize support for different positions of the panel.

[0048] Specifically, the limiting support block 22 and / or the standard support block 25 are detachably mounted on the top edge of the support base plate 21. Function: When there are small differences in the panel structure, one or more limiting support blocks and standard support blocks on the support base plate can be quickly replaced by adjusting them. The replaced limiting support blocks and standard support blocks on the support base plate can adapt to the changed structure of the panel, and not only the screen pasting tooling body does not need to be changed, but also the entire screen pasting tooling support does not need to be significantly changed, thereby reducing the man-hours for tooling replacement, improving production efficiency, and reducing manufacturing costs. The support base plate 21 is prefabricated with a number of holes for locking the standard support blocks 25. Function: In this way, when the panel support position changes, the locking position of the standard support block can be adjusted to achieve universalization of the panel positioning support.

[0049] Specifically, the screen mounting tool support 20 further includes a positioning hole 23, the number of which includes two, and the two positioning holes 23 are respectively arranged at the two short sides of the support bottom plate 21; the screen mounting tool body 10 further includes a positioning column 13, the number of which includes two, and the two positioning columns 13 are respectively arranged at the two short sides of the groove part 14; the positioning hole 23 is used to be positioned on the positioning column 13 of the screen mounting tool body 10. Function: The matching of the positioning hole and the positioning column enables the screen mounting tool support to match the groove part more accurately.

[0050] Specifically, the screen mounting tool support 20 also includes panel positioning holes 24, which are distributed at the center of two short sides and one long side of the support bottom plate 21. The panel positioning holes 24 are used to position the panel 30. Function: The panel positioning holes can better coordinate with the panel.

[0051] Specifically, the screen-mounting tool body 10 further includes a quick-release structure 12, the number of which includes two, the two quick-release structures 12 are respectively arranged at the two short sides of the top of the body base 11, and the groove portion 14 is arranged between the two quick-release structures 12, and the quick-release structure 12 is used to realize the rapid assembly and disassembly of the screen-mounting tool support 20. It should be noted that since the quick-release structure itself is a prior art, it will not be described in detail here.

[0052] Specifically, the screen pasting tool body 10 is made of bakelite material, and the screen pasting tool support 20 is made of aluminum alloy material.

[0053] Specifically, Figures 8 to 9 As shown, the pressure-holding fixture 60 includes a first pressure block 61 and a second pressure block 62. The first pressure block 61 and the second pressure block 62 are of different sizes. The first pressure block 61 and the second pressure block 62 are respectively used to be placed in the length and width directions of the screen 50. Note: After simulation analysis and actual verification, the pressure-holding fixture is arranged on the outer contour of the screen, and the gap between the panel and the screen is better. Due to the difference in the length and width of the screen, the universal pressure-holding fixture is made into two or more pressure blocks (such as the first pressure block 61 and the second pressure block 62), which are respectively placed in the length and width directions of the screen.

[0054] Specifically, the pressure-maintaining tool 60 is made of bakelite, and the bottoms of the first pressing block 61 and the second pressing block 62 are respectively pasted with a first foam 63 and a second foam 64 with soft and high friction. Function: The pressure-maintaining tool is usually made of bakelite. Since the screen surface is glass or film material, in order to protect the surface of the glass or film material from being damaged by bakelite, the first foam 63 and the second foam 64 with soft and high friction are pasted on the contact surface between the bakelite and the screen to prevent scratching of the screen.

[0055] The following describes the use of universal pressure-holding tooling:

[0056] Place the panel and glue dispensing process such as Figures 10 to 12 As shown:

[0057] (1) The screen pasting tool support is assembled onto the screen pasting tool body using the quick-release structure 12 and the positioning column 13.

[0058] (2) The panel is pre-processed, such as cleaning and removing the packaging bag, etc. The panel 30 is placed on the screen pasting tool support of the above-assembled (1) screen pasting tool through the limiting support block 22 and the standard support block 25.

[0059] (3) Use the equipment to apply glue 40 on the set track of the panel to complete the glue dispensing process.

[0060] Screen pasting, pressure holding and curing process Figures 13 to 14 As shown:

[0061] (4) The screen is adsorbed by the adsorption mechanism, and the camera on the device is used to take a picture to align the position, and the screen 50 is attached to the panel.

[0062] (5) Place a pressure-maintaining tool 60 (pressure-maintaining block) around the screen.

[0063] like Fig.15 As shown, the following is an explanation of the use of the universal pressure-maintaining tooling in conjunction with the dispensing, screen pasting, and pressure-maintaining assembly line conveyor belt:

[0064] The screen pasting tool body 10 and the screen pasting tool support 20 of the split screen pasting tool have been assembled into one by a quick-disassembly structure.

[0065] (1) The panel should be pre-processed, such as cleaning and removing the packaging bag.

[0066] (2) The panel 30 is placed on the screen attaching tooling through the limiting support block 22 and the standard support block 25.

[0067] (3) Use the equipment to apply glue 40 on the set track of the panel to complete the glue dispensing process.

[0068] (4) The screen is adsorbed by the adsorption mechanism, and the camera on the device is used to take a picture to align the position, and the screen 50 is attached to the panel.

[0069] (5) Place a pressure-holding tool 60 (pressure-holding block) around the screen. Since the production cycle of the dispensing and screen-mounting processes is about 60 seconds, and the pressure-holding curing stage takes 30 minutes, in order to ensure continuous production, about 40 sets of screen-mounting tooling and pressure-holding tooling need to be produced.

[0070] (6) Remove the product from the tooling.

[0071] To summarize, the present invention proposes a universal screen pasting and pressure-maintaining tooling solution, which can save tooling costs. The screen pasting tooling and pressure-maintaining tooling can be applicable to panel structures of different projects to achieve universalization. When the panel structures are different, they can be quickly replaced by adjusting the limit support blocks and standard support blocks supported by the screen pasting tooling, thereby reducing the working hours for replacing tooling, improving production efficiency, and reducing manufacturing costs. Therefore, the pain points of high cost and large footprint of customized tooling are solved, and an application method of the screen pasting and pressure-maintaining tooling is proposed.

[0072] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
