A structure for assisting ITO film and conductive glass to form a touch screen

Abstract

The present invention relates to an electronic display production technology, specifically a structure that assists in laminating an ITO film to conductive glass to form a touch screen. The structure comprises a laminating frame for supporting an ITO film coated with glue on one side, a movable pressure roller that can penetrate the laminating frame, a bonding mechanism, and a deflection mechanism; the bonding mechanism is used to drive the pressure roller to fluctuate along the length of the ITO film. Lamination is performed using a line-to-line lamination method, and the deflection mechanism drives the laminating frame to deflect, thereby shortening the length of the transition portion as much as possible. The angle of the portion to be bonded is automatically adjusted according to the progress of the bonding, keeping the portion to be bonded attached to the extension as much as possible. This reduces the probability of bubble formation in the intermediate section and helps the ITO film and conductive glass to fully bond by changing the angle, thereby increasing the overlap of the surface-to-surface bonding.

Description

Technical Field

[0001] The present invention relates to an electronic display production technology, in particular to a structure in which an auxiliary ITO film is laminated with conductive glass to form a touch screen. Background Art

[0002] Touch screen is the most widely used input technology in modern electronic devices. Touch screens can be roughly divided into capacitive and resistive types. It allows electronic products to be operated directly by touching the screen with fingers.

[0003] The main raw materials required for touch screen production include conductive glass, ITO film, and glue. The first step in production is processing the conductive glass, which requires cutting, grinding, and polishing. After processing, the conductive glass is placed in a cleaning machine to ensure that the surface is dust-free and contaminant-free.

[0004] Next, the ITO film preparation process begins. ITO film is a key material for touch screens, boasting excellent conductivity and transparency. ITO film is primarily prepared by depositing the material onto conductive glass using a sputtering technique to form a thin film. The prepared ITO film requires cutting and trimming to improve coverage and precision.

[0005] Next, the ITO film and conductive glass are bonded together. This process requires the use of glue to adhere the ITO film and conductive glass together to form the touch screen structure. After bonding, the touch screen is sent to a curing machine for curing to improve the hardness and adhesion of the glue.

[0006] Finally, there's the touchscreen post-processing process. Post-processing primarily includes surface treatment and testing. Surface treatment involves polishing and coating the touchscreen surface to improve its smoothness and wear resistance. Testing primarily involves using specialized instruments and equipment to test and measure the touchscreen's electrical, optical, and mechanical properties to ensure that the touchscreen meets quality requirements.

[0007] At present, in the widely used ITO film and conductive glass bonding process, the ITO film and conductive glass need to be pre-bonded; during the pre-bonding process, the bonding area of ​​the film will be larger than the area of ​​the conductive glass, resulting in voids and bubbles; the industry eliminates the voids and bubbles by subsequent back-and-forth squeezing and scraping with a scraper; in theory, it is necessary to ensure that the bonding area of ​​the film and the conductive glass are consistent; however, in the actual production process, since the film itself has a certain elasticity, although there are no bubbles between the film and the conductive glass after the scraper treatment, it is actually due to the extrusion of the scraper and the bonding of the external glue that causes the film to shrink; once heated and cured, the film stretches and voids appear again.

[0008] The reason is that the pasting accuracy is not well controlled during the bonding process, and the high overlap of both sides cannot be guaranteed by surface-to-surface bonding. Summary of the Invention

[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0064] See also Figures 1 to 23 As an embodiment of the present invention, the auxiliary ITO film is bonded to the conductive glass to form a touch screen structure, including a laminating frame 2 for carrying an ITO film 33 coated with glue on one side, and a pressing roller 21 that can penetrate the laminating frame 2 and move;

[0065] Among them, a circle of extension is set on the inner edge of the laminating frame 2, and the edge of the ITO film 33 coated with glue on one side is placed on the extension, with the glue-coated side facing upward; the extension is used to support the edge of the ITO film 33, and then the entire ITO film 33 is lifted.

[0066] It should be noted that the ITO film 33 in this application is the conventional ITO film, which is an N-type oxide semiconductor - indium tin oxide, with high conductivity, high visible light transmittance, certain mechanical hardness and good chemical stability.

[0067] Therefore, after glue is applied to one side of the ITO film 33, the entire film body can be lifted up by supporting the edge of the ITO film 33 through the extension part, and the center of the film will not be sunken and deformed, causing the film body to fall off from the extension part.

[0068] The structure for bonding the auxiliary ITO film and the conductive glass to form a touch screen also includes a bonding mechanism for driving the pressure roller 21 to rise and fall as it moves along the length direction of the ITO film 33; when driving the pressure roller 21 along the length direction of the ITO film 33, the bonding mechanism first drives the pressure roller 21 to rise, and when the pressure roller 21 approaches one side of the conductive glass 32, the top of the pressure roller 21 reaches the same level as the conductive glass 32; then the pressure roller 21 maintains its top level with the conductive glass 32 and continues to move toward the other side of the conductive glass 32; after the pressure roller 21 passes the other side of the conductive glass 32, the bonding mechanism drives the pressure roller 21 to descend until it reaches the same initial height.

[0069] It should be noted that the outer layer of the pressing roller 21 is a soft rubber layer with a certain elasticity. The pressing roller 21 squeezes the ITO film 33 so that the side of the ITO film 33 coated with glue is bonded to the conductive glass 32 .

[0070] The bonding mechanism drives the pressure roller 21 to move in a composite motion, including vertical motion and horizontal motion. Specifically, the motion can be divided into three stages. The horizontal motion is uniform in the three stages, while the vertical motion only exists in the first and third stages.

[0071] Specifically, in the first stage, the bonding mechanism drives the pressure roller 21 to move horizontally while also driving it upward. As the pressure roller 21 rises, it penetrates the laminating frame 2 from below, thereby lifting the ITO film 33. At the end of the first stage, the top of the pressure roller 21 is flush with the conductive glass 32, and the pressure roller 21 approaches one side of the conductive glass 32, initiating bonding.

[0072] In the second stage, the bonding mechanism only drives the pressure roller 21 to move horizontally, keeping the top of the pressure roller 21 flush with the conductive glass 32, and drives the pressure roller 21 to move horizontally at a constant speed toward the other side of the conductive glass 32. At the end of the second stage, the pressure roller 21 passes over the other side of the conductive glass 32.

[0073] In the third stage, the bonding mechanism drives the pressure roller 21 to move horizontally while also driving the pressure roller 21 to descend. During the descent of the pressure roller 21, the pressure roller 21 continuously moves downward and gradually separates from the conductive glass 32. The pressure roller 21 penetrates from the top of the coating frame 2 to the bottom until the pressure roller 21 descends to the same height as the initial height of the first stage.

[0074] At this point, the bonding operation of the ITO film 33 is completed.

[0075] The structure of the touch screen formed by bonding the auxiliary ITO film and the conductive glass also includes a deflection mechanism that controls the angle of the ITO film 33 to adaptively adjust as the pressure roller 21 moves. The deflection mechanism is mechanically coordinated with the bonding mechanism. When the pressure roller 21 moves along the length direction of the ITO film 33, the deflection mechanism drives the ITO film 33 to deflect.

[0076] To better illustrate, please combine Figure 24 and Figure 25 The figure is only a schematic diagram of the status and is not a real-life figure in proportion to the size.

[0077] Figure 24 The state diagram of the first stage is shown in Figure 2. Figure 25This is a state diagram of the second stage. It is not difficult to see from the attached figure that during the bonding process, a part of the ITO film 33 will be adhered to the conductive glass 32 after the action of the pressure roller 21, forming a bonding part; and the part to be bonded will still be attached to the extension part of the inner edge of the coating frame 2, forming a part to be bonded; wherein, there will be a transition part between these two parts. In the present invention, the coating frame 2 is driven to swing by the swing mechanism to shorten the length of the transition part as much as possible, and the angle of the part to be bonded is automatically adjusted according to the bonding progress, so as to keep the part to be bonded attached to the extension part as much as possible; on the one hand, it can reduce the probability of bubble formation in the middle section, and on the other hand, the change in angle also helps the ITO film 33 to be completely bonded to the conductive glass 32, and its principle is similar to that of mobile phone film.

[0078] As a further solution of the present invention, please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 13 ,as well as Figure 14 The bonding mechanism includes a horizontally movable translation member 14 and a fixed first track frame 18; a guide sleeve 15 is vertically fixed at the end of the translation member 14, and the guide sleeve 15 is slidably matched with the lifting member 16;

[0079] The pressure roller 21 is rotatably arranged at the top end of the lifting member 16, and the bottom end of the lifting member 16 is rotatably engaged with the rotating shaft 17. The first track frame 18 is an isosceles trapezoidal shape, and bonding guide grooves 1801 are opened along the two sides and top edge of the isosceles trapezoidal first track frame 18. The rotating shaft 17 passes through the bonding guide groove 1801 and rolls with it.

[0080] The horizontal movement of the translation member 14 drives the rotating shaft 17 to move along the trajectory of the bonding guide groove 1801. In the process of moving along the bonding guide groove 1801, the rotating shaft 17 starts to climb up from one side of the bonding guide groove 1801. After rising to a predetermined height, it moves along a horizontal straight line and finally goes downhill along the other side.

[0081] The lifting member 16 and the pressure roller 21 are driven by the rotating shaft 17 to rise and fall during the process of moving along the length direction of the ITO film 33; wherein, the pressure roller 21 first rises, and when the pressure roller 21 is close to one side of the conductive glass 32, the top of the pressure roller 21 reaches the same level as the conductive glass 32; then the pressure roller 21 keeps its top flush with the conductive glass 32 and continues to move toward the other side of the conductive glass 32; after the pressure roller 21 passes the other side of the conductive glass 32, the pressure roller 21 descends until it is consistent with the initial height.

[0082] As a further solution of the present invention, please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 ,as well as Figure 11 , a sleeve 19 is fixedly mounted on the side wall of the guide housing 15, and the sleeve 19 is slidably fitted with the first guide post 20;

[0083] Both ends of the No. 1 guide column 20 are fixed to two sets of truss assemblies, which include a No. 1 truss 501, a No. 2 truss 502, and a No. 3 truss 503 distributed from top to bottom and fixed to each other;

[0084] There are multiple groups of No. 1 guide posts 20, and the multiple groups of No. 1 guide posts 20 are fixed on the No. 2 truss 502 and the No. 3 truss 503 respectively;

[0085] Axle journals 1701 are formed on both sides of the central position of the rotating shaft 17 . A plurality of rollers are rollingly engaged with a side of the shaft journal 1701 facing the first track frame 18 . The rollers are rollingly engaged with the first track frame 18 .

[0086] By providing the sleeve 19 and the No. 1 guide post 20, the guide sleeve 15 can only move horizontally, thereby constraining the translation member 14 fixed to the guide sleeve 15 to move horizontally; in addition, the shaft necks 1701 on both sides of the rotating shaft 17 can constrain the axial position of the rotating shaft 17, and the friction between the shaft necks 1701 and the first track frame 18 can be reduced by means of the rolling cooperation between the rollers and the first track frame 18.

[0087] As a further solution of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 ,as well as Figure 5 The truss assembly is fixed to the platform 3, and a reinforcing rib 504 is provided between the truss assembly and the platform 3;

[0088] The laminating frame 2 is fixed to the upper part of the movable frame 1, the center of the movable frame 1 is rotatably matched with the top of the support arm 4, the lower part of the support arm 4 is fixedly connected to the stage 3, and a driving mechanism connected to the translation member 14 is also provided on the stage 3, and the driving mechanism is used to drive the translation member 14 to move from one side to the other along the length direction of the ITO film 33;

[0089] The yaw mechanism is connected to the movable frame 1 , and the first track frame 18 is fixed to the truss assembly via a connector 22 .

[0090] When the driving mechanism is running, it drives the translation member 14 to move from one side to the other along the length direction of the ITO film 33; and then drives the bonding mechanism to perform the bonding action. Because the bonding mechanism and the deflection mechanism are mechanically coordinated, during the bonding process, the deflection mechanism also drives the movable frame 1 and the coating frame 2 to deflect, and finally drives the ITO film 33 to deflect.

[0091] The present invention adopts a mechanical matching method to establish a logical matching relationship between the bonding mechanism and the deflection mechanism. Compared with the common inductive control or electric control, there is basically no error and the failure rate is also lower.

[0092] As a further solution of the present invention, please refer to Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 13 ,as well as Figure 14 , the yaw mechanism includes a second track frame 28 fixedly connected to the first track frame 18, and a support frame 25 cooperating with the second track frame 28;

[0093] The support frame 25 cooperates with the side edge of the movable frame 1, and a second guide column 27 is fixed to the truss assembly. The second guide column 27 is slidably matched with a sleeve 26, and the sleeve 26 is fixed to the follower frame 23. A sliding sleeve 24 is slidably provided on the follower frame 23, and the sliding sleeve 24 is fixed to the support frame 25;

[0094] A swing guide groove 2801 is provided on the second track frame 28, and the swing guide groove 2801 is in an "M" shape. A rotating column 29 is rotatably installed on one side of the sliding sleeve 24, and the rotating column 29 is rollingly engaged in the swing guide groove 2801; a clearance groove 2301 is provided at the lower part of the follower frame 23, and the rotating shaft 17 passes through the clearance groove 2301 and movably cooperates with it.

[0095] The two sides of the swing guide groove 2801 are parallel to the two sides of the bonding guide groove 1801, and the elevation difference between the swing guide groove 2801 and the bonding guide groove 1801 is the same, that is, if the difference between the highest point and the lowest point in the swing guide groove 2801 is H1, and the difference between the highest point and the lowest point in the bonding guide groove 1801 is H2, then H1 and H2 are equal;

[0096] The swing guide groove 2801 includes three track low points and two track high points. The heights of the three track low points are consistent, and the heights of the two track high points are also consistent.

[0097] The bonding guide groove 1801 contains two low points of the track and a high point track. The two end points of the high point track are respectively on the same plumb line with the two high points of the track in the swing guide groove 2801; the two low points of the track in the bonding guide groove 1801 and the two low points of the track on both sides of the swing guide groove 2801 are also on the same plumb line.

[0098] Because the rotating shaft 17 passes through the clearance groove 2301, and the length of the clearance groove 2301 is greater than the elevation difference of the bonding guide groove 1801, when the rotating shaft 17 moves, the rotating shaft 17 only drives the follower frame 23 to move horizontally. When the rotating shaft 17 rises and falls, the rotating shaft 17 only moves within the clearance groove 2301. Therefore, it can be understood that the movement trajectory of the follower frame 23 and the movement trajectory of the translator 14 are exactly the same, both moving horizontally along a straight line.

[0099] When the follower frame 23 moves horizontally, the sliding sleeve 24 will follow the movement, but the sliding sleeve 24 can rise or fall relative to the follower frame 23. Specifically, when the rotating column 29 moves along the swing guide groove 2801, it initially follows the rise and fall of the pressure roller 21 synchronously. During this process, the rotating column 29 drives the movable frame 1 to swing and tilt through the sliding sleeve 24 and the support frame 25; when the pressure roller 21 reaches the end of the first stage, the rotating column 29 also reaches the corresponding position, and then the pressure roller 21 moves horizontally, but the rotating column 29 will be constrained by the "V"-shaped trajectory in the center of the swing guide groove 2801 and move downward, thereby driving the sliding sleeve 24 to move downward, and finally driving the support frame 25 to move downward. The downward movement of the support frame 25 will drive the movable frame 1 to swing; when the rotating column 29 moves to the bottom of the "V"-shaped trajectory, the movable frame 1 swings to the horizontal, and then the rotating column 29 continues to move, which will drive the movable frame 1 to swing in the opposite direction.

[0100] As a further solution of the present invention, please refer to Figure 12 A bracket is fixedly provided at the end of the support frame 25, and an embedded column 30 is rotatably provided on the top of the bracket. An edge track part 31 is fixedly provided on the edge of the movable frame 1, and an embedding groove 3101 is opened on the edge track part 31, and the embedded column 30 is rollingly embedded in the embedding groove 3101.

[0101] The support frame 25 moves up and down along the swing guide groove 2801 and the embedded column 30 cooperates with the embedded groove 3101 to drive the edge track member 31 and the movable frame 1 to swing around the top of the support arm 4.

[0102] Because the deflection mechanism is driven by the rotating shaft 17, and the rotating shaft 17 is driven by the bonding mechanism, a strict logical coordination relationship is established between the deflection mechanism and the bonding mechanism, and they coordinate with each other to ensure that the bonding action matches the swinging action of the ITO film 33.

[0103] As a further solution of the present invention, please refer to Figure 2 、 Figure 5 and Figure 6 , a supporting member 6 and a connecting member 7 are fixedly mounted on the platform 3, the driving mechanism includes a servo motor 8 mounted on the connecting member 7, and two sets of chain transmission assemblies are provided on the supporting member 6;

[0104] The chain drive assembly includes four sprockets 10 rotatably mounted on the support member 6, and the four sprockets 10 are distributed at the four inflection points of the rectangle. The four sprockets 10 are connected by a chain 11. The output end of the servo motor 8 is connected to one of the sprockets 10 in one group of the chain drive assemblies through a reducer.

[0105] The two adjacent sprockets 10 in the two groups of chain transmission assemblies are connected via two spur gears 9 , and the translation member 14 is connected to the chains 11 in the two groups of chain transmission assemblies via a transmission mechanism.

[0106] When the servo motor 8 is working, it drives one of the sprockets 10 in one set of chain drive assemblies to rotate through the reducer, and the sprocket 10 drives the other three sprockets 10 in the entire chain drive assembly to rotate through the chain 11, so that the chain drive assembly is running;

[0107] The actively rotating sprocket 10 then drives one of the sprockets 10 in the other chain drive assembly to rotate with the help of two spur gears 9, ultimately achieving synchronous operation of the two chain drive assemblies; and the chains 11 in the two chain drive assemblies run in opposite directions.

[0108] It is noted that since the four sprockets 10 in the same chain drive assembly are distributed at the four inflection points of the rectangle, when the translation member 14 is driven by the transmission mechanism to move to the end of the travel of the translation member 14, the translation member 14 does not return immediately; instead, it pauses for a moment before returning, so that time can be reserved for the intermediate replacement of the ITO film 33 and the conductive glass 32.

[0109] As a further solution of the present invention, please refer to Figure 7 , the transmission mechanism includes a knot column 12 connected to one of the links in the chain 11, and the knot column 12 is rotatably matched with the slider 13;

[0110] A sliding groove is provided at the bottom of the translation member 14 along its length direction, and a rolling track 1401 is provided on the inner side wall of the sliding groove. A ball 1301 is rollingly engaged with the outer side of the slider 13, and the ball 1301 rolls in cooperation with the rolling track 1401.

[0111] Because the knot 12 is rotatably coordinated with the slider 13, and the slider 13 is coordinated through the ball 1301 and the raceway 1401, the chain 11 will not undergo angular deflection in the process of driving the translation member 14 through the chain 11; and when the knot 12 runs along the direction of the slide groove, the chain 11 will not undergo angular deflection.

[0112] If the chain 11 yields and deflects, the knot column 12 will inevitably be tilted, and the tilt of the knot column 12 will inevitably drive the slider 13 to tilt. Obviously, the slider 13 cannot be tilted due to the restriction of the sliding groove.

[0113] In addition, there are two second track frames 28 , and the tops of the two second track frames 28 are fixed by a top frame 37 .

[0114] As a further solution of the present invention, please refer to Figure 22 and Figure 23 The structure of the touch screen formed by laminating the auxiliary ITO film and the conductive glass further includes a transfer mechanism disposed above the film frame 2 for fixing the conductive glass 32, and the transfer mechanism cooperates with the production line;

[0115] When the ITO film 33 on the laminating frame 2 is completely adhered to the conductive glass 32, the transfer mechanism moves to a position offset from the laminating frame 2, and puts down the fixed conductive glass 32, while clamping the next conductive glass to be coated;

[0116] At the same time, the corresponding film feeding device will also feed new ITO film 33 to the laminating frame 2 again.

[0117] Note that the present invention Figures 1 to 23 The conductive glass 32 in the apparatus is framed.

[0118] The transfer mechanism includes a top stabilizing frame 34 , and lateral clamping members 35 are movably provided on both sides of the top stabilizing frame 34 , and horizontal hook teeth are provided on the lower edges of the lateral clamping members 35 .

[0119] The conductive glass 32 to be coated can be clamped and fixed by bringing the lateral clamping members 35 on both sides together; and the conductive glass 32 after coating can be released by controlling the lateral clamping members 35 on both sides to move away from each other.

[0120] As a further solution of the present invention, the front and rear sides of the top stabilizing frame 34 are both slidably provided with hanging seats, the lateral clamping members 35 are fixed on the hanging seats, and two sets of electric telescopic rods 36 are symmetrically installed at the central position of the top stabilizing frame 34, and the telescopic ends of the electric telescopic rods 36 are fixed to the lateral clamping members 35 through straight handles.

[0121] By controlling the two electric telescopic rods 36 to work, the lateral clamping members 35 on both sides can be driven to move toward or away from each other, thereby achieving the function of fixing and releasing the conductive glass 32 .

[0122] In addition, the suspension bracket and the lateral clamping member 35 can share the weight of the lateral clamping member 35 and the conductive glass 32 held therein, thereby preventing the electric telescopic rod 36 from being subjected to the weight of the conductive glass 32 for a long time and causing stress yielding and failure to extend and retract normally.

[0123] The above embodiments are exemplary rather than restrictive, so any technical solution that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
