Description

Technical Field

[0001] The invention relates to the technical field of heat pressing devices, and more specifically, to a pressing device for touch screen processing. Background Art

[0002] A touch screen is an input method that allows users to interact with a device by touching images or graphics on the screen. They are widely used in mobile phones, tablets, computers and various electronic devices. Touch screen processing and lamination refers to the production process of the touch screen, which usually involves combining multiple layers and materials (such as the screen and the touch screen) together to form a complete touch screen assembly. This process is critical to the performance, appearance and durability of the touch screen.

[0003] The touch screen lamination process is usually carried out in a dust-free workshop. Before lamination, in order to ensure the stability of the position of the screen and the touch screen outer screen, the screen and the touch screen outer screen are usually placed in a lamination groove that matches them, or clamped by an elastic clamping plate to prevent them from displacement during the lamination process. However, in this case, when the upper party (such as the touch screen outer screen) is pressed and moved downward, friction will occur between the inner cavity of the lamination groove or the elastic clamping plate. The friction will cause uneven pressure distribution and cause its position in the lamination groove or on the clamping plate to be unstable, which will not only affect the precise alignment, but also affect the bonding effect. At the same time, severe friction will also cause scratches on the touch screen outer screen or the screen surface, thereby causing unnecessary losses. Summary of the invention

DETAILED DESCRIPTION

[0021] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0022] like Figures 1 to 8 As shown, a pressing device for processing a touch screen according to an embodiment of the present invention comprises a placing frame 1, two sets of clamping plates 2 are slidably mounted on the bottom wall of the inner cavity of the placing frame 1, springs 3 are fixedly mounted between the two sets of clamping plates 2 and the inner cavity wall of the placing frame 1, and further comprises: The anti-friction component includes a movable groove 4 opened on a splint 2, the inner cavities of the two groups of movable grooves 4 are fixedly installed with magnet sheets 6, the opposite sides of the two groups of magnet sheets 6 are magnetically installed with splints 2 5, the two groups of splints 2 5 are slidably installed with the inner cavities of adjacent movable grooves 4, the rear sides of the two groups of splints 2 are fixedly installed with tooth plates 7, a gear 1 8 is meshingly installed between the two groups of tooth plates 7, the gear 1 8 is rotatably installed with the inner cavity wall of the placement frame 1, a pull rod 33 is fixedly installed on the side wall of the movable groove 4 on one side, the pull rod 33 is slidably installed with the placement frame 1, a heater 9 is fixedly installed on the inner cavity wall of the placement frame 1, and a flattening component is arranged above the placement frame 1.

[0023] The flattening assembly includes a pressing frame 15 arranged above the placing frame 1, a reciprocating screw 16 is rotatably installed in the inner cavity of the pressing frame 15, a motor 17 is fixedly installed on one side of the pressing frame 15, the output end of the motor 17 is fixedly installed with one end of the reciprocating screw 16, a movable plate 18 is threadedly installed on the reciprocating screw 16, the movable plate 18 is slidably installed with the inner cavity wall of the pressing frame 15, and a pressure roller 19 is rollably installed at the bottom of the movable plate 18; A bottom plate 10 is fixedly installed at the bottom of the placement frame 1, a top plate 11 is fixedly installed on the upper part of the bottom plate 10, an electric telescopic rod 12 is fixedly installed on the top plate 11, a push plate 14 is fixedly installed at the output end of the electric telescopic rod 12, a pressing frame 15 is slidably installed with the bottom of the push plate 14, a spring 35 is evenly fixedly installed between the pressing frame 15 and the push plate 14, a U-shaped frame 13 is contacted with the top of the push plate 14, and the U-shaped frame 13 is sealed and slidably installed with the output end of the electric telescopic rod 12.

[0024] It should be noted that, first, the staff pulls the pull rod 33 to drive one group of splints 2 to move outward in the inner cavity of the placement frame 1. When the right splint 2 moves, it will drive the lower toothed plate 7 to move synchronously. The lower toothed plate 7 will drive the upper toothed plate 7 to move in the opposite direction through the gear 8, and the upper toothed plate 7 will drive the other group of splints 2 to move outward synchronously. At this time, the two groups of splints 2 can move away from and squeeze the adjacent springs 3. After leaving a distance for placing the screen between the two groups of splints 2, the screen and the touch outer screen that have been coated with adhesive are aligned and placed on the bottom wall of the inner cavity of the placement frame 1 in turn, and then the pulling force on the pull rod 33 is canceled. Under the action of the two groups of springs 3, the two groups of springs 3 return to their original state. In the initial state, the two groups of clamping plates 1 2 will be pushed to move synchronously inward and squeeze the outer side of the screen. Since the screen and the touch outer screen have not been pressed together at this time, there will be a gap between the screen and the touch outer screen. The two groups of clamping plates 1 2 will clamp the screen, and the two groups of clamping plates 2 5 will clamp the touch outer screen above the screen. Through the setting of the two groups of toothed plates 7 and the gear 1 8, the two groups of clamping plates 1 2 and the clamping plates 2 5 can be moved synchronously and clamp the screen and the touch outer screen respectively, so that the screen and the touch outer screen can be continuously kept at the center of the pressing during the clamping process, which can avoid the situation in which the screen and the touch outer screen are offset due to different elastic forces on both sides of the elastic clamping component under long-term use, and can effectively improve the pressing effect; Turn on the electric telescopic rod 12 and the heater 9, the heater 9 will heat the inner cavity of the placement frame 1, and the heating will help the fluidity and permeability of the adhesive, which can speed up the bonding efficiency of the screen and the touch outer screen. The output end of the electric telescopic rod 12 will push the push plate 14 to move downward, and the U-shaped frame 13 will follow the push plate 14 to move downward synchronously. The U-shaped frame 13 will first contact the top of the placement frame 1. At this time, the output end of the electric telescopic rod 12 continues to extend, and the push plate 14 will push the pressing frame 15 to continue to move downward through the spring 2 35. When the pressing frame 15 contacts the top of the touch outer screen, the output end of the electric telescopic rod 12 continues to extend, which will cause the push plate 14 to push the pressing frame 15 downward through the spring 2 35 to elastically press the touch outer screen downward, and press the touch outer screen together with the screen below it. The pressing frame 15 can be used to press the four sides and apply uniform pressure to ensure the adhesive on all sides. Evenly distributed and begin to solidify, while reducing the risk of misalignment caused by movement, when the pressing frame 15 presses the touch outer screen to move downward, the touch outer screen will drive the clamp 2 5 to slide downward in the inner cavity of the movable groove 4, and the clamp 2 5 moves while moving and moves downward on the magnetic surface of the magnet sheet 6, during the pressing process of the touch outer screen and the screen, the clamp 2 5 is magnetically attracted to the magnet sheet 6 and moves, and the touch outer screen drives the clamp 2 5 to move downward and then stops, and the clamp 2 5 will automatically adsorb at the stop position, and the touch outer screen is clamped by the clamp 2 5, and moves synchronously with the touch outer screen during the pressing process, which can avoid friction of the touch outer screen during the pressing process, and can effectively improve the uniformity of pressure distribution and the stability of the movement of the touch outer screen, so that the touch outer screen and the screen can be accurately aligned, and at the same time, it can avoid the situation where the surface of the touch outer screen is scratched due to severe friction, thereby avoiding unnecessary losses.

[0025] like Figures 2 to 5 As shown, slots 20 are provided on the front and rear side walls of the U-shaped frame 13, and the inner cavities of the two groups of slots 20 are provided with gears 21, and the two groups of gears 21 are rotatably mounted with the movable plate 18. The bottom walls of the inner cavities of the two groups of slots 20 are evenly fixed with teeth 22 that match the gears 21, and the opposite sides of the two groups of gears 21 are fixed with cross plates 1 23.

[0026] It should be noted that when the bottom of the pressing frame 15 contacts the top of the touch outer screen and presses it with the screen, the pressing roller 19 will also contact the top of the touch outer screen, and the motor 17 will be turned on. The output shaft of the motor 17 drives the reciprocating screw 16 to rotate, so as to drive the movable plate 18 to move back and forth left and right in the inner cavity of the pressing frame 15. When the movable plate 18 moves, it will drive the pressing roller 19 to move synchronously, so that the pressing roller 19 can roll back and forth left and right on the top of the touch outer screen. After the four sides are pressed, pressure can be applied from the top to the outside, which helps to expel the air on the top, reduce the risk of bubble formation, and ensure that the adhesive can fill all the gaps well, so that the entire top surface of the touch outer screen can be pressed on the screen, and the movable plate 1 When the inner cavity of the pressing frame 15 moves, the gear 2 21 will be driven to move synchronously in the inner cavity of the slot 20. The gear 21 will mesh with the tooth 22, and the movable plate 18 will drive the gear 21 to rotate through the tooth 22 while moving. When the gear 21 rotates, the cross plate 1 23 will be driven to rotate. At this time, the front and rear two groups of cross plates 1 23 move back and forth left and right while rotating, which can improve the fluidity of the gas in the inner cavity of the placement frame 1 and the U-shaped frame 13. The uniformity of the temperature in the inner cavity of the placement frame 1 and the U-shaped frame 13 can be improved through the gas flow, which can avoid the situation where the temperature in some areas is too high or too low, resulting in inconsistent material properties or decreased adhesive performance, thereby effectively improving the bonding effect between the touch outer screen and the screen during the pressing process.

[0027] like Figure 5 and Figure 8 As shown, a fixed rod 25 is provided below the reciprocating screw 16, and the fixed rod 25 is fixedly installed with the inner cavity wall of the pressing frame 15. A round tube 27 is sleeved on the outer wall of the fixed rod 25, and the round tube 27 is rotatably installed with the movable plate 18. A ball 28 is rollingly installed on the inner cavity wall of the round tube 27, and a spiral groove 26 matched with the ball 28 is opened on the outer wall of the fixed rod 25. Cross plates 29 are provided on both sides of the movable plate 18, and two groups of cross plates 29 are fixedly installed with the round tube 27.

[0028] Through openings 24 are evenly formed on the front and rear sides of the pressing frame 15 .

[0029] It should be noted that, while the motor 17 drives the movable plate 18 to move back and forth left and right through the reciprocating screw 16, the movable plate 18 will drive the circular tube 27 to move synchronously. Through the cooperation of the ball 28 and the spiral groove 26, the ball 28 will move spirally along the inner cavity of the spiral groove 26, so that the ball 28 can drive the circular tube 27 to move horizontally on the fixed rod 25 while rotating on the movable plate 18. At this time, the movable plate 18 can be reciprocated while the circular tube 27 will drive the cross plates 29 on both sides to rotate. The cross plates 29 on both sides are driven to rotate by the movable plate 18 during the reciprocating movement, which can effectively improve the fluidity of the gas in the inner cavity of the pressing frame 15, thereby effectively promoting the uniformity of temperature. Through the arrangement of the slots 20 and the multiple groups of through-ports 24, the fluidity of the airflow between the inner cavity of the pressing frame 15 and its outer side can be promoted, which can effectively improve the balance of the temperature between the touch outer screen and the outer side of the screen. The cooperation of the pressure roller 19 and the cross plate 1 23 further improves the stability of the temperature uniformity, thereby effectively improving the pressing and bonding effects.

[0030] like Figure 5 and Figure 6 As shown, the top wall of the U-shaped frame 13 is uniformly provided with grooves 30 , and an elastic rope 31 is fixedly installed between the inner cavity top wall of each group of grooves 30 and the top of the push plate 14 .

[0031] A sealing ring 32 is fixedly mounted on the bottom of the U-shaped frame 13 .

[0032] It should be noted that, while the output end of the electric telescopic rod 12 drives the push plate 14 to move downward, the push plate 14 will drive the U-shaped frame 13 and the sealing ring 32 to move synchronously. After the sealing ring 32 contacts the top of the placement frame 1, the output end of the electric telescopic rod 12 continues to extend to push the push plate 14 to move downward. At this time, the push plate 14 will stretch the elastic rope 31, and the stretching force of the elastic rope 31 will pull the U-shaped frame 13 downward to squeeze the sealing ring 32, which can improve the sealing between the U-shaped frame 13 and the placement frame 1, avoid the loss of heat in the placement frame 1 and the U-shaped frame 13, and effectively improve the heating efficiency, thereby effectively improving the thermal pressing efficiency of the touch outer screen and the screen.

[0033] like Figure 2 and Figure 7 As shown, the opposite sides of the two groups of second clamping plates 5 are provided with anti-skid patterns, and the opposite sides of the two groups of second clamping plates 5 and the adjacent magnet sheets 6 are both provided with smooth surfaces.

[0034] The bottom wall of the inner cavity of the placement frame 1 is provided with a butt plate 34 , which is slidably mounted with the placement frame 1 and the bottom plate 10 .

[0035] The two sets of clamping plates 2 5 are both made of magnetically absorbable materials, and the distance between the two sets of clamping plates 1 2 is greater than the length of the abutment plate 34 .

[0036] It should be noted that, by setting the anti-slip texture on the second splint 5, the friction between the second splint 5 and the touch outer screen can be increased, and the friction between the second splint 5 and the touch outer screen can be avoided, thereby improving the effect of the touch outer screen driving the second splint 5 to move downward. By setting the smooth surface of the second splint 5 and the magnet sheet 6, the friction can be reduced and the sliding of the second splint 5 on the magnet sheet 6 can be facilitated. After the pressing is completed, the output end of the electric telescopic rod 12 is controlled to contract to drive the U-shaped frame 13 and the pressing frame 15 away from the placement frame 1, and then the pull rod 33 is pulled to make the splint 1 2 and the second splint 5 away from the pressed touch outer screen and screen, and then the bottom end of the abutment plate 34 is pushed upward to remove the pressed touch outer screen and screen. When preparing to press the next group of touch outer screens and screens, the second splint 5 can be manually pushed to move to the uppermost side in the inner cavity of the movable groove 4. At this time, preparations for the next group of pressing can be made.

[0037] Working principle: first, the staff pulls the pull rod 33, and the two sets of toothed plates 7 and gear 1 8 cooperate to achieve the synchronous movement of the two sets of clamping plates 1 2 away from each other, and then the screen and the touch screen are placed in the placement frame 1 in turn, and then the pulling force on the pull rod 33 is cancelled, and the clamping plates 1 2 and 2 5 will elastically clamp the screen and the touch screen respectively, and the electric telescopic rod 12 is controlled to drive the push plate 14 to move downward, and the push plate 14 will drive the U-shaped frame 13 and the pressing frame 15 to move downward. After the sealing ring 32 contacts the placement frame 1, the push plate 14 continues to move downward to pull the elastic rope 31 so that the U-shaped frame 13 squeezes the sealing ring 32, thereby achieving the seal between the U-shaped frame 13 and the placement frame 1, and at the same time, the push plate 14 continues to move downward to push the pressing frame 15 to press the touch screen on the screen, and the touch screen will drive the clamping plates 2 5 to move synchronously while moving. , which can prevent the touch screen from generating friction during the movement, and at the same time, start the motor 17 to make the movable plate 18 reciprocate left and right. Through the cooperation of the gear 21 and the tooth 22, and the cooperation of the ball 28 and the spiral groove 26, the movable plate 18 can respectively drive the cross plate 1 23 and the cross plate 2 29 to rotate during the reciprocating movement. The arrangement of the slot 20 and the through-port 24 can promote the circulation of airflow, thereby improving the balance of the temperature of the screen and the outside of the touch screen, and maintaining the stability of uniform temperature, thereby facilitating the pressing of the screen and the touch screen. After the pressing is completed, the electric telescopic rod 12 is controlled to make the pressing frame 15 and the U-shaped frame 13 move away upward, and make the clamping plate 1 2 and the clamping plate 2 5 move away from the screen and the touch screen, and then the abutment plate 34 is pushed upward to remove the pressed screen and the touch screen as a whole.

[0038] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
