Description

Technical Field

[0001] This utility model relates to the field of touch screen production equipment technology, and in particular to a touch screen production pressing machine. Background Technology

[0002] With the popularization and development of electronic devices, touch screens, as an important component of human-computer interaction, directly affect the user experience in terms of quality and performance. Touch screens are typically composed of multiple layers of materials, including a glass cover, a touch sensor layer, and a display panel. These materials are bonded together with optical adhesive and then pressed together by a laminator to form a whole. The precise lamination process is key to ensuring that the touch screen has good electrical connectivity and physical stability.

[0003] Patent CN219143437U discloses a pressing device for a touch screen. This patent uses a combination of a cylinder and a pressure plate to press the touch screen, and uses a servo motor and a threaded rod to achieve slow movement of the inclined block. Then, through the contact of the inclined block with the push rod and the compression of the first spring by the push rod, the push plate and clamping plate firmly hold the touch screen on the fixed frame, solving the problem of the laborious and cumbersome fixation of the touch screen in the prior art. However, this patent still has some shortcomings in actual use. This patent only relies on mechanical pressure for pressing and lacks an effective heating function, which makes the adhesion between the optical adhesive layer and the material poor. This results in the inability of the material layers to adhere tightly, which can easily lead to problems such as air bubbles and gaps, thereby reducing the quality of the touch screen.

[0004] Therefore, there is an urgent need to provide a touch screen production pressing machine with heating function. Summary of the Invention

[0005] In order to overcome the shortcomings of existing patents that lack heating function, resulting in insufficient bonding strength between the optical adhesive layer and the material, which affects the quality of the touch screen, this utility model provides a touch screen production pressing machine with heating function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a touchscreen production pressing machine, comprising a support base, a bracket, a placement platform, an electric push rod, a movable rod, a pressure plate, an electronic suction cup, a temperature controller, and a heating tube. The support base has a bracket fixed to its top, and a placement platform located in front of the bracket is positioned on the top of the support base. A square groove is provided in the center of the placement platform to accommodate the touchscreen to be processed. An electric push rod is installed in the center of the bracket, and a pressure plate is connected to the movable rod of the electric push rod. The pressure plate is used to press the touchscreen. An electronic suction cup is embedded inside the square groove of the placement platform to fix the touchscreen. A temperature controller is installed on the side of the placement platform, and a heating tube is connected to the temperature controller to heat the adhesive on the touchscreen.

[0007] As a preferred embodiment of this invention, the heating tube is arranged in a manner that surrounds a square groove.

[0008] As a preferred embodiment of this utility model, it also includes telescopic guide rods. Multiple telescopic guide rods are fixedly connected to the bracket, and the telescopic ends of the telescopic guide rods are connected to the top of the pressure plate to guide the pressure plate.

[0009] As a preferred technical solution of this utility model, it also includes a dual-axis motor, a screw, a threaded block, a limiting plate, an electric slide rail, an electric slider, and a positioning block. The dual-axis motor is installed inside the placement platform. The output shafts at both ends of the dual-axis motor are connected to the screw. The screw is threaded with a threaded block. A limiting plate for limiting the position of the touch screen is fixed on the threaded block. Electric slide rails are provided on the sides of the two limiting plates. An electric slider is installed on the electric slide rail. A positioning block is fixed on the electric slider. The two positioning blocks are designed in opposite directions.

[0010] As a preferred technical solution of this utility model, it also includes a top plate, a reset spring and a handle. The top plates are symmetrically distributed and slidably installed in the square groove of the placement platform to lift the touch screen. The top plate is connected to the placement platform by a reset spring, and the two top plates are fixedly connected to the handle.

[0011] As a preferred technical solution of this utility model, it also includes stabilizing components, and symmetrically distributed stabilizing components are fixedly connected to both sides of the support base.

[0012] As a preferred technical solution of this utility model, it also includes a safety light curtain, and the top of the placement platform is provided with a safety light curtain located on both sides of the square groove.

[0013] Compared with the prior art, the present invention has the following technical effects: 1. By adding a temperature controller and heating tube device, the heating function is realized. In this way, the adhesive layer between the touch screen components can be heated and softened before pressing, making the optical adhesive easier to flow and fill the gap between the materials. This helps to improve the bonding strength between the optical adhesive layer and the material, ensuring that the layers of the touch screen can be tightly bonded, thereby effectively improving the pressing quality and reducing the defect rate caused by poor bonding.

[0014] 2. Through the coordinated operation of dual-axis motors, screws, limit plates, electric slide rails, electric sliders, and positioning blocks, the position of the touch screen components is finely adjusted and corrected, ensuring that the touch screen components are in the center of the square groove, thus avoiding poor pressing due to positional deviation.

[0015] 3. The material ejection mechanism, consisting of a top plate, a return spring, and a handle, allows for easy and convenient removal of the pressed touchscreen without complicated operating procedures, thus improving work efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] Example 1: Please refer to Figures 1-5A touchscreen production pressing machine includes a support base 1, a bracket 2, a placement platform 3, an electric push rod 4, a movable rod 5, a telescopic guide rod 6, a pressure plate 7, an electronic suction cup 8, a temperature controller 9, a heating element 10, a stabilizer 21, and a safety light curtain 22. The support base 1 has the bracket 2 welded to its top. The placement platform 3, located in front of the bracket 2, is positioned on the top of the support base 1. A square groove in the center of the placement platform 3 accommodates the touchscreen to be processed. An electric push rod 4 is installed in the center of the bracket 2. The bottom end of the movable rod 5 of the electric push rod 4 is connected to the pressure plate 7, which is used for pressing the touchscreen. Four telescopic guide rods 6, symmetrically distributed in pairs, are fixedly connected to the bracket 2. The telescopic ends of the telescopic guide rods 6 are connected to the top of the pressure plate 7 to guide its movement and ensure stable movement. An electronic suction cup 8 is embedded inside the square groove of the placement platform 3 to fix the touchscreen and ensure stable positioning during the pressing process. A temperature controller 9 is installed on the right side of the placement platform 3. The temperature controller 9 is connected to a heating tube 10, which is used to heat the adhesive on the touch screen to promote the bonding effect during the pressing process and make the touch screen more tightly pressed. In addition, the heating tube 10 is arranged in a way that surrounds the square groove to ensure uniform heat distribution, so that all parts of the touch screen component are heated evenly during the heating process, avoiding local overheating or uneven heating. The support base 1 is fixed with symmetrically distributed stabilizers 21 on both the left and right sides. The stabilizers 21 are used to increase the overall stability of the equipment and prevent displacement or tilting caused by external forces or vibrations of the equipment itself during operation, ensuring safety during the pressing process and smooth operation of the equipment. The top of the placement platform 3 is provided with safety light curtains 22 located on the left and right sides of the square groove. The safety light curtains 22 are set to improve the safety of operation. When the operator's hand or other objects accidentally enter the pressing area, the safety light curtains 22 can immediately detect and trigger the emergency stop mechanism to prevent accidents and protect the operator's personal safety.

[0025] First, the touchscreen assembly to be pressed is placed on the placement platform 3, ensuring that the touchscreen is accurately positioned within the square groove in the center of the platform 3. At this point, the electronic suction cup 8 inside the placement platform 3 is activated, generating appropriate suction to firmly adhere and fix the touchscreen in its position, preventing displacement during subsequent pressing. Then, a suitable heating temperature is set via the temperature controller 9, and the heating element 10 starts working to preheat the touchscreen assembly on the placement platform 3. The purpose of this is to soften the adhesive layer between the touchscreen components, facilitating a smoother pressing operation and ensuring a tight bond between the layers of the touchscreen. Once the preset heating temperature is reached, the electric push rod 4 is activated, the movable rod 5 extends, and thus the pressure plate 7 moves downward. The pressure plate 7 gradually approaches the touch screen assembly and finally applies uniform pressure to achieve the pressing of the touch screen assembly. During this process, the heating tube 10 continues to work to ensure that the adhesive layer can flow fully under pressure, thereby strengthening the bonding strength between the layers. After pressing is completed, the heating tube 10 stops heating and the system enters the cooling stage. The pressure plate 7 continues to maintain a certain pressure for a period of time until the touch screen assembly is completely cooled and shaped, ensuring a stable bond between the layers. Subsequently, the movable rod 5 of the electric push rod 4 retracts, the pressure plate 7 leaves the touch screen assembly, the electronic suction cup 8 closes, and the touch screen is released. Finally, the operator removes the pressed touch screen assembly from the placement table 3 and performs a quality inspection. Once it is confirmed to be correct, it is the finished product.

[0026] Example 2: Based on Example 1, please refer to... Figure 6 It also includes a dual-axis motor 11, a screw 12, a threaded block 13, a limiting plate 14, an electric slide rail 15, an electric slider 16, and a positioning block 17. The dual-axis motor 11 is installed on the rear side inside the placement platform 3. The output shafts at both ends of the dual-axis motor 11 are connected to the screw 12. The screw 12 is threaded with a threaded block 13. The threaded block 13 is fixed with a limiting plate 14 for limiting the position of the touch screen. The two limiting plates 14 are provided with electric slide rails 15 on their sides. The electric slide rails 15 are equipped with electric sliders 16. The electric sliders 16 are fixed with positioning blocks 17. The two positioning blocks 17 are designed in opposite directions, so that the two positioning blocks 17 can move from both sides of the touch screen assembly towards the center. This can ensure that the touch screen assembly is accurately centered before pressing. The bidirectional movement design can effectively correct horizontal position deviations.

[0027] After the touchscreen assembly is placed in the square slot, the dual-axis motor 11 starts, and its output shafts at both ends drive the two screws 12 to rotate. When the screws 12 rotate, the threaded block 13 drives the limiting plate 14 to move along the screws 12 and move closer to the touchscreen until the limiting plate 14 contacts the edge of the touchscreen, thus initially limiting the position of the touchscreen. Then, the two electric slide rails 15 drive their respective positioning blocks 17 to move through the electric slider 16. The two positioning blocks 17 move synchronously towards the center and contact the front and rear sides of the touchscreen assembly, thereby correcting the position of the touchscreen assembly and ensuring that the touchscreen assembly is in the center of the square slot, avoiding the problem of poor pressing due to position deviation.

[0028] Please see Figure 5 It also includes a top plate 18, a reset spring 19, and a grip 20. The top plates 18, which are symmetrically distributed on the left and right sides, are slidably installed in the square groove of the placement platform 3 to lift the touch screen. The reset spring 19 is connected between the top plate 18 and the placement platform 3 to provide reset for the top plate 18. The grip 20 is welded together to the two top plates 18.

[0029] When it is necessary to remove the pressed touch screen, the operator can pull the handle 20 to move the two top plates 18 upwards, lifting the touch screen from the square slot, making it easy for the operator to remove the touch screen. When the operator releases the handle 20, the return spring 19 will return to its original state, pulling the top plate 18 back to the initial position, ready for the next touch screen pressing operation.
