Description

Technical Field

[0001] This utility model belongs to the field of human-computer interaction technology, and in particular relates to a bonding and assembly equipment for multi-curved touch display products. Background Technology

[0002] In the production process of touch display products, the bonding of the touch film to the glass is a key process that directly affects the display effect and touch performance of the product. Currently, the mainstream bonding equipment on the market uses cylindrical rollers for roll bonding. Its working principle is to press the touch film onto a flat or single fixed curvature glass surface by rolling the cylindrical rollers.

[0003] With the development of consumer electronics, AR, VR, medical devices and other fields, the demand for multi-curved touch display products is increasing. Since the contact surface of the cylindrical roller is cylindrical, it can only maintain line contact with a plane or a single fixed curvature surface. It cannot adapt to the characteristics of continuous curvature change of the surface curvature of multi-curved products, which leads to problems such as bubbles, wrinkles and loose bonding when multi-curved products are bonded, or even cannot be bonded at all, which reduces the quality during production.

[0004] To address these issues, we propose a multi-curved touch display product bonding and assembly equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing cylindrical roller bonding equipment cannot adapt to multi-curved surface products and has poor versatility, and to propose a bonding and assembly equipment for multi-curved surface touch display products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-curved touch display product bonding and assembly equipment includes a placement platform. An alignment platform and a glass fixing fixture are fixedly connected to the upper surface of the placement platform. Multi-curved glass is disposed above the glass fixing fixture. A multi-axis robotic arm is disposed above the placement platform. A first connecting flange is fixedly connected to the inner wall of the multi-axis robotic arm. A second connecting flange is disposed below the first connecting flange. A spherical airbag is fixedly connected to the bottom end of the second connecting flange. An air pump is fixedly connected to the upper surface of the placement platform. A regulating valve is disposed on the upper surface of the air pump. A solenoid valve is fixedly connected to the upper surface of the air pump. An air pipe is fixedly connected to the top end of the solenoid valve. The other end of the air pipe is fixedly connected to the outer surface of the spherical airbag.

[0008] Preferably, the alignment platform has two first adsorption holes inside, and the upper surface of the alignment platform is fixedly connected with a plurality of positioning protrusions arranged at equal intervals.

[0011] Preferably, a plurality of connecting bolts are arranged at equal intervals above the first connecting flange, and the bottom end of each connecting bolt passes through the first connecting flange and is threadedly connected to the second connecting flange.

After inflation, the spherical airbags can adaptively deform according to the curvature of the multi-curved glass, enabling the bonding of complex curved surface products such as hyperboloids, multi-segment curved surfaces, and spherical curved surfaces. This solves the technical bottleneck of traditional equipment, eliminating the need to design special fixtures for multi-curved surface products with different curvatures. The spherical airbags can be adapted to various products by adjusting the position of the regulating valve and the multi-axis robotic arm, reducing production costs and shortening changeover cycles. The adaptive bonding of the spherical airbags ensures the bonding accuracy between the touch film and the multi-curved glass, reducing defects such as bubbles and wrinkles.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A multi-curved touch display product bonding and assembly equipment includes a placement platform 1. An alignment platform 2 and a glass fixing fixture 3 are fixedly connected to the upper surface of the placement platform 1. The alignment platform 2 has two first adsorption holes 13 inside. A plurality of positioning protrusions 14 arranged at equal intervals are fixedly connected to the upper surface of the alignment platform 2. The first adsorption holes 13 can be connected to an external negative pressure device. The first adsorption holes 13 and the positioning protrusions 14 are used to increase the firmness of the touch film during positioning, avoid film displacement during pre-alignment, and ensure the alignment accuracy of subsequent adsorption processes.

[0025] A multi-curved glass 4 is mounted above the glass fixing fixture 3, and a multi-axis robotic arm 5 is mounted above the placement platform 1. The glass fixing fixture 3 has four second suction holes 15 inside, and the top of each second suction hole 15 is in contact with the bottom surface of the multi-curved glass 4. The second suction holes 15 are connected to an external negative pressure pipe, and the negative pressure of the second suction holes 15 is used to ensure the stable connection between the multi-curved glass 4 and the glass fixing fixture 3.

[0026] The inner wall of the multi-axis robotic arm 5 is fixedly connected with a first connecting flange 6. Four fixing bolts 16 are provided above the placement platform 1. The bottom end of each fixing bolt 16 passes through the multi-axis robotic arm 5 and is threadedly connected to the placement platform 1. The placement platform 1 and the multi-axis robotic arm 5 can be quickly fixed by fixing the fixing bolts 16. At the same time, the multi-axis robotic arm 5 can be disassembled from the placement platform 1 by rotating the fixing bolts 16.

[0027] A second connecting flange 7 is provided below the first connecting flange 6. A spherical airbag 8 is fixedly connected to the bottom end of the second connecting flange 7. A plurality of connecting bolts 17 are arranged at equal intervals above the first connecting flange 6. The bottom end of each connecting bolt 17 passes through the first connecting flange 6 and is threadedly connected to the second connecting flange 7. The first connecting flange 6 and the second connecting flange 7 are fixed by the connecting bolts 17, so that the multi-axis robotic arm 5 can drive the spherical airbag 8 to move in multiple directions, and can also rotate the connecting bolts 17 to quickly separate the two.

[0028] An air pump 9 is fixedly connected to the upper surface of the placement platform 1. An regulating valve 10 is provided on the upper surface of the air pump 9. A first hard anodized coating 18 is provided above the alignment platform 2, and a second hard anodized coating 19 is provided below the alignment platform 2. Through the cooperation of the first hard anodized coating 18 and the second hard anodized coating 19, it can withstand long-term friction from the edge of the touch film or the positioning protrusion without scratching. At the same time, the oxide layer has high density, which can prevent the platform from being corroded by alcohol, cleaning agents, etc. that may come into contact with it during the bonding process.

[0029] An air pump 9 has a solenoid valve 11 fixedly connected to its upper surface, and an air pipe 12 fixedly connected to the top of the solenoid valve 11. A first low surface energy coating 20 is provided above the first hard anodized coating 18, and a second low surface energy coating 21 is provided below the second hard anodized coating 19. The first low surface energy coating 20 and the second low surface energy coating 21 prevent the adhesive diaphragm from sticking to the alignment platform 2 due to pressure or temperature. At the same time, the coating does not block the first adsorption hole 13, ensuring the stability of negative pressure adsorption and not affecting the pre-positioning accuracy.

[0030] The other end of the trachea 12 is fixedly connected to the outer surface of the spherical airbag 8. The outer surface of the spherical airbag 8 is provided with a low-viscosity silicone coating 22, and the outer surface of the low-viscosity silicone coating 22 is provided with a wear-resistant lubricating coating 23. The low-viscosity silicone coating 22 provides controllable adhesion force to achieve stable adsorption and residue-free separation of the touch diaphragm. The wear-resistant lubricating coating 23 can improve the wear resistance of the airbag surface, reduce friction damage with the diaphragm, and extend the service life of the airbag.

[0031] The working principle of this utility model is as follows: In use, firstly, the multi-axis robotic arm 5, air pump 9, and solenoid valve 11 are powered on. The touch diaphragm is placed on the alignment platform 2. The platform achieves mechanical positioning through positioning protrusions 14. Simultaneously, the first suction hole 13 initiates negative pressure suction to fix the touch diaphragm, completing pre-alignment. The air delivery speed of the air pump 9 is adjusted by the regulating valve 10. Then, the air pump 9 is started and the solenoid valve 11 is opened, thereby inflating the spherical airbag 8 through the air tube 12, causing the spherical airbag 8 to expand to a preset state. Then, the multi-axis robotic arm 5 drives the spherical airbag 8 to move above the alignment platform 2. After adjusting the position and angle of the spherical airbag 8, it is then inflated by electrostatic discharge. The pre-aligned touch film is adsorbed by adsorption force or low viscosity. Then, the spherical airbag 8 with the adsorbed touch film is transferred to the glass fixing fixture 3 by the multi-axis robotic arm 5. The robotic arm drives the spherical airbag 8 to move towards the multi-curved glass 4. Under the action of gas pressure, the spherical airbag 8 contacts the glass surface and deforms adaptively according to the curvature of the glass, so as to evenly squeeze and adhere the touch film to the glass surface. After the adhesion is completed, the air pump 9, solenoid valve 11 and air tube 12 work together to release air from the spherical airbag 8, causing it to shrink and the adsorption force between it and the touch film disappears. Then, the multi-axis robotic arm 5 moves to separate the spherical airbag 8 from the touch film, thus completing the adhesion process.
