Description

Technical Field

[0001] This utility model belongs to the field of screen assembly technology, and specifically relates to a touch screen assembly device. Background Technology

[0002] With the rapid development of electronic devices, touchscreens, as a crucial component of human-computer interaction, have a significant impact on product quality due to their manufacturing processes and assembly precision. Zero-gap bonding between curved touchscreens and LCD screens is a technology that achieves seamless bonding between the touchscreen (TP) and the LCD screen (LCM). This technology reduces light reflection and loss, improving image clarity, while also reducing the ingress of air and dust, thus enhancing image fidelity.

[0003] Currently, most curved screen bonding processes on the market use frame bonding technology. The gap between the curved touch screen and the LCD screen is large, usually more than 1mm. Due to the refraction and scattering of light, the display effect is affected. In addition, a small number of processes use full bonding technology, but full bonding of curved screens is expensive, which increases the cost of use for consumers. Utility Model Content

[0042] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-6 This utility model provides the following technical solution: a touch screen assembly device, comprising:

[0044] Rack 1;

[0045] Fitting jig 2;

[0046] Slide rail mechanism 3;

[0047] Vacuuming mechanism 4;

[0048] Rack 1 includes:

[0049] Frame 101;

[0050] The electric telescopic rod 102 is fixedly installed inside the frame 101, and its telescopic end is fixedly connected to the fitting fixture 2.

[0051] Fitting fixture 2 includes:

[0052] Upper jig 201;

[0053] Lower fixture 202;

[0054] A rubber frame 203 is fixedly connected to the bottom of the upper fixture 201, and a rubber groove 204 is fixedly connected to the upper surface of the lower fixture 202. Magnetic strips 205 are installed inside both the rubber frame 203 and the rubber groove 204.

[0056] Vacuum pump 401 is fixedly installed on the upper surface of upper fixture 201;

[0057] The suction pipe 402 has one end fixedly connected to the suction end of the vacuum pump 401, and the other end passes through the upper fixture 201 and is fixedly connected to it.

[0058] In this embodiment, the vacuum mechanism 4 effectively removes air between the curved touchscreen and the LCD screen, allowing them to fit tightly together under atmospheric pressure. This significantly reduces the gap between the two screens, improving the fit and ensuring the touch sensitivity and display effect of the curved touchscreen. It also reduces touch delay and display deviation caused by air gaps. The design of the rubber frame 203 and rubber groove 204, along with the built-in magnetic strip 205, not only achieves a good seal during the bonding process and ensures the vacuum effect, but also buffers the impact force during bonding, preventing damage to the curved touchscreen. Furthermore, it facilitates the precise positioning of the upper and lower fixtures, ensuring accurate alignment between the curved touchscreen and the LCD screen and improving the product qualification rate.

[0059] Furthermore, an electric telescopic rod 25 is fixedly installed on the top of the frame 101;

[0060] The upper fixture 201 has a cylinder 6 fixedly connected inside, a suction cup 7 fixedly connected to the bottom end of the cylinder 6, the suction cup 7 communicates with the cylinder 6, a piston 8 is slidably installed inside the cylinder 6, a push-pull rod 9 is fixedly connected to the upper surface of the piston 8, and a connecting rod 10 is fixedly connected to the top end of the push-pull rod 9.

[0061] The telescopic end of the electric telescopic pole 25 is fixedly connected to the connecting rod 10.

[0062] Specifically, the electric telescopic rod 25 is an XTL50 electric push rod with a stroke of 50mm and an accuracy controlled within ±0.02mm. The cylinder 6 inside the upper fixture 201 is made of stainless steel with an inner diameter of 15mm. The suction cup 7 is made of nitrile rubber, which has good elasticity and adsorption performance. The clearance between the piston 8 and the cylinder 6 is controlled between 0.01-0.02mm to ensure good airtightness. By controlling the retraction of the electric telescopic rod 25, the push-pull rod 9 and the piston 8 are moved upward, creating a negative pressure inside the suction cup 7. The upper structure of the touch screen (which is an LCD screen) to be bonded is adsorbed by the suction cup 7. At the same time, the curved touch screen is placed on the lower fixture 202, with the LCD screen and the curved touch screen aligned vertically.

[0063] Furthermore, the slide rail mechanism 3 includes:

[0064] Electromagnetic slide rail 1 301, electromagnetic slider 1 302 is slidably mounted on the surface of electromagnetic slide rail 1 301, electromagnetic slide rail 2 303 is fixedly connected to the upper surface of electromagnetic slider 1 302, electromagnetic slider 2 304 is slidably mounted on the surface of electromagnetic slide rail 2 303, and electric telescopic rod 3 305 is fixedly connected to the lower surface of electromagnetic slide rail 1 301.

[0065] Specifically, electromagnetic slide rail 1 (301) and electromagnetic slide rail 2 (303) are precision electromagnetic slide rails of model EMS-15, with a positioning accuracy of ±0.01mm and strokes of 300mm and 200mm respectively. Electric telescopic rod 3 (305) is an electric push rod of model XTL80, used to adjust the height of slide rail mechanism 3.

[0066] Furthermore, a support plate 11 is fixedly connected to the upper surface of the electromagnetic slider 2 304, a dispensing mechanism 12 is fixedly connected to the upper surface of the support plate 11, and a cooling mechanism 13 is fixedly connected to the upper surface of the support plate 11.

[0067] Specifically, the dispensing mechanism 12 and cooling mechanism 13 integrated on the support plate 11 achieve multi-dimensional movement through the slide rail mechanism 3, so as to complete the dispensing and cooling process of the curved touch screen without transferring the product, reducing the waiting time between processes and improving production efficiency.

[0068] Furthermore, the dispensing mechanism 12 includes:

[0069] The glue container 1201 has a glue dispensing pipe 1202 fixedly connected to its bottom. A pressure pump 1203 is installed on the surface of the glue dispensing pipe 1202. A solenoid valve 1204 is fixedly connected to one end of the glue dispensing pipe 1202. A glue dispensing nozzle 1205 is fixedly connected to one side of the solenoid valve 1204.

[0070] Specifically, the glue container 1201 has a capacity of 500ml and is made of transparent acrylic material for easy observation of the glue volume. The pressure pump 1203 is a miniature pneumatic pressure pump with a working pressure of 0.3-0.6MPa, which can increase the glue dispensing volume. Through the coordinated movement of the electromagnetic slide rail 1 301, electromagnetic slider 1 302, electromagnetic slide rail 2 303 and electromagnetic slider 2 304 of the slide rail mechanism 3, the glue dispensing mechanism 12 is moved to the periphery of the curved touch screen. After the solenoid valve 1204 is opened, the glue is discharged from the glue container 1201 through the glue dispensing pipe 1202 and the glue dispensing nozzle 1205, dripping around the periphery of the curved touch screen. By starting the pressure pump 1203, the flowing glue can be pressurized to increase the glue dispensing volume.

[0071] Furthermore, the cooling mechanism 13 includes:

[0072] The exhaust fan 1301 has an air guide pipe 1302 fixedly connected to its output end, and an exhaust hole 1303 is provided on the surface of the air guide pipe 1302.

[0073] Specifically, the exhaust fan 1301 is an axial flow fan with an air volume of 100m³ / h, and the air duct 1302 is a PVC pipe with a diameter of 30mm. The surface is evenly opened with exhaust holes 1303 with a diameter of 2mm to ensure that the cooling air is evenly blown onto the surface of the touch screen. After the LCD screen and the curved touch screen are bonded together, the upper fixture 201 and the lower fixture 202 are separated by the electric telescopic rod 102. At this time, the cooling mechanism 13 is moved above the curved touch screen by the slide rail mechanism 3, and the exhaust fan 1301 is started. The cold air is blown onto the bonded curved touch screen through the air duct 1302 and the exhaust holes 1303 to accelerate the curing of the adhesive layer.

[0074] Furthermore, the electric telescopic rods 102 are arranged in pairs, with their telescopic ends fixedly connected to the upper fixture 201 and the lower fixture 202, respectively.

[0075] Specifically, both the upper fixture 201 and the lower fixture 202 of the fitting fixture 2 are made of aviation aluminum material, which is lightweight and has good rigidity. By controlling the movement of the electric telescopic rod 102, the upper fixture 201 moves down and the lower fixture 202 moves up, so that the rubber frame 203 and the rubber groove 204 are embedded and matched. Under the adsorption of the magnetic strip 205, the upper and lower fixtures are precisely positioned, and the rubber frame 203 and the rubber groove 204 are tightly fitted to form a sealed space.

[0076] All electrical equipment in this device is powered by an external power source and is controlled to operate and shut down via a matching control switch.

[0077] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
