Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, and in particular to a touch screen lamination and curing device. Background Technology

[0002] Touchscreens, as a core component of human-computer interaction in modern electronic devices, are widely used in smartphones, tablets, industrial control panels, and automotive display systems. During the manufacturing process, the lamination and curing of touchscreens are key steps to ensure their optical performance, structural stability, and lifespan. Touchscreen lamination and curing equipment, as the core equipment for realizing this process, is mainly used to bond and cure multiple layers of materials such as glass cover plates, touch sensing layers, optical adhesives, and displays under precisely controlled pressure and temperature conditions to achieve high-quality bonding with high light transmittance, no bubbles, and no misalignment. As touchscreens develop towards thinner, lighter, higher-resolution, and more flexible designs, higher requirements are placed on the precision, stability, and automation of lamination and curing equipment.

[0003] However, existing touch screen lamination and curing devices generally suffer from uneven pressure and poor buffering performance. Traditional structures often use rigid pressure plates to press directly down, which is difficult to adapt to the bonding requirements of products with different thicknesses or curved surfaces. During high-pressure operations, stress concentration can easily cause the screen edges to peel off or the middle area to be damaged, affecting product yield. At the same time, some devices lack effective guidance and elastic compensation mechanisms, which can lead to uneven loading or shaking during the pressurization process, affecting the consistency of lamination.

[0004] Therefore, it is necessary to design a touch screen lamination and curing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the common problems of uneven pressure and poor buffering in existing touch screen lamination and curing devices, which often use rigid pressure plates to directly press down, lacking guidance and elastic compensation, and are prone to delamination or damage due to stress concentration, as well as the disadvantages of uneven loading and vibration, affecting the consistency of bonding, this utility model provides a touch screen lamination and curing device.

[0006] Technical Solution: A touch screen lamination and curing device includes a support frame, a servo motor, rollers, a conveyor belt, a first protective cover, an electric push rod, a connecting plate, connecting cylinders, slide rods, a first spring, and a pressure mold plate. A servo motor is fixedly connected to the upper left side of the support frame. Rollers are rotatably connected to the front and rear sides of the top of the support frame.

A pressure mold plate is connected between the bottoms of the multiple slide rods.

[0007] As an improvement to the above solution, the surface of the conveyor belt is made of Teflon material.

[0008] As an improvement to the above solution, it also includes a first mounting block and a cleaning brush. The first mounting blocks are fixedly connected to the left and right sides of the top front of the support frame, and the cleaning brush is fixedly connected between the two first mounting blocks. The bottom of the cleaning brush slides in contact with the surface of the conveyor belt.

The output shaft of the servo motor 2 extends to the right, passes through the support frame 1, and connects to the left end of the front roller 3. A conveyor belt 4 is wound between the two rollers 3. The surface of the conveyor belt 4 is made of Teflon material. The first protective cover 5 is installed at the top center of the support frame 1. An electric push rod 6 is installed on the top of the protective cover 5. The telescopic rod of the electric push rod 6 passes downward into the first protective cover 5 and is connected to a connecting plate 7. Multiple connecting cylinders 8 are evenly arranged and welded to the bottom of the connecting plate 7. A sliding rod 9 is slidably connected inside each connecting cylinder 8. A first spring 10 is connected between each connecting cylinder 8 and the corresponding sliding rod 9. The top end of each first spring 10 is welded to the inner top wall of the corresponding connecting cylinder 8, and the bottom end of each first spring 10 is welded to the top end of the corresponding sliding rod 9. A pressure mold plate 11 is connected between the bottoms of the multiple sliding rods 9.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first mounting block 12, a cleaning brush 13, a second mounting block 14, a connecting rod 15, a second spring 16, and a roller 17. The first mounting blocks 12 are bolted to the left and right sides of the top front of the support frame 1. The cleaning brush 13 is bolted between the two first mounting blocks 12. The bottom of the cleaning brush 13 slides in contact with the surface of the conveyor belt 4. The second mounting blocks 14 are bolted to the left and right sides of the top front of the support frame 1. A connecting rod 15 is slidably sleeved between the two mounting blocks. The second spring 16 is sleeved between the two second mounting blocks 14 and the corresponding connecting rod 15 on the left and right sides. Both ends of the two connecting rods 15 extend upward to above the conveyor belt 4. Rollers 17 are respectively provided at the ends of the two connecting rods 15 that are close to each other. Each roller 17 is covered with an anti-slip rubber sleeve, which slides in contact with the surface of the conveyor belt 4. The anti-slip rubber sleeve is made of silicone material.

[0024] like Figure 1 and Figure 6 As shown, it also includes a second protective cover 18, a fan 19 and a loading box 20. The second protective cover 18 is installed on the rear side of the top of the support frame 1. The fan 19 is installed on the left and right sides of the top of the second protective cover 18 respectively. The loading box 20 is placed on the lower rear side of the support frame 1. The loading box 20 has a handle on the upper rear side.

[0025] When this device is needed, firstly, the touch screen assembly to be laminated and cured is placed on the surface of the conveyor belt 4. The servo motor 2 is started, and the output shaft of the servo motor 2 drives the front roller 3 to rotate. Since the conveyor belt 4 is wound between the two rollers 3, the conveyor belt 4 is driven to run smoothly in the front-back direction, conveying the touch screen to the working area directly below the pressure mold plate 11. When the touch screen reaches the designated position, the electric push rod 6 is activated, and its telescopic rod extends downward, driving the connecting plate 7 to descend vertically. Multiple connecting cylinders 8 move down synchronously. The slide rod 9 slidably connected inside each connecting cylinder 8 is in the first spring 10. Under the action of the connecting plate 7, the pressure mold plate 11, which is connected to the bottom of multiple slide bars 9, gradually presses against the surface of the touch screen to achieve uniform pressure. During this process, the first spring 10 is compressed, which can effectively buffer the impact force and ensure uniform pressure distribution, preventing damage to the touch screen structure due to excessive local stress. The surface of the conveyor belt 4 is made of Teflon material, which has excellent high temperature resistance and low surface energy characteristics. It can effectively prevent colloids from adhering to the surface of the conveyor belt 4 during high temperature and pressure, avoiding contamination of subsequent products, while extending the service life of the conveyor belt 4 and ensuring continuous and stable operation.

[0026] While pressurizing, the conveyor belt 4 continues to run, causing the touchscreen to move slowly under the pressurizing mold plate 11, completing the dynamic lamination process. The cooperation between the pressurizing mold plate 11 and the conveyor belt 4 achieves tight adhesion of the various layers of the touchscreen material, promotes adhesive flow and air release, and improves lamination quality. To ensure the cleanliness of the conveyor belt 4 surface, the cleaning brush 13 continuously slides in contact with the surface of the conveyor belt 4, effectively removing residual particles or impurities and preventing contamination of subsequent products. To further improve conveying stability, the connecting rods 15 slide through the second mounting blocks 14 on the left and right sides, respectively, and are connected by the first... Two springs 16 provide elastic downward pressure. The roller 17 slides in contact with the surface of the conveyor belt 4 through the silicone anti-slip sleeve on its surface, which plays a role in limiting and preventing deviation, while enhancing the running stability of the conveyor belt 4 under load. After lamination, the touch screen enters the rear area with the conveyor belt 4. The fan 19 is started and blows cooling air downward to quickly cool down the touch screen that has been hot-pressed or pre-cured, accelerate the curing process of the adhesive, and improve production efficiency. Finally, the finished product is conveyed to the rear end, where the operator can remove it and put it into the loading box 20. The handle makes it easy to handle and manage materials.
