Description

Technical Field

[0001] This utility model relates to the field of capacitive touch film installation technology, and in particular to a capacitive touch film installation structure. Background Technology

[0002] Capacitive touch films are commonly used in touchscreen devices, such as smartphones and tablets. The mounting structure includes the film layer, adhesive, and support frame. The capacitive touch film mounting structure refers to the mechanical and adhesive system that fixes the capacitive touch sensing film to the display screen or device casing. Its core objective is to ensure touch accuracy, anti-interference, and durability.

[0003] During the installation of capacitive touch films, OCA adhesive may develop air bubbles due to variations in the installation process. This is primarily caused by insufficient pressure applied to the capacitive touch during installation, preventing effective air expulsion. These air bubbles result in an uneven touch film surface, affecting the product's aesthetics, and can also cause stress concentration, impacting operational sensitivity. Therefore, those skilled in the art have provided a capacitive touch film installation structure to address the problems mentioned in the background section. Utility Model Content

A negative pressure pump with its suction end located inside the processing table is installed at one end. Lifting hydraulic rods are installed at the four corners of the upper part of the processing table. A connecting block connected to the lifting frame is installed at the upper end of each lifting hydraulic rod. A positioning frame is installed at the upper part of the processing table, and the capacitive touch film body is installed inside the positioning frame. Two sets of equidistantly distributed positioning hydraulic rods are installed at the upper end of the positioning frame. A pressure strip is installed on one side of the telescopic end of each positioning hydraulic rod. A motor is installed on the inner wall of the upper end of the lifting frame. A screw rod rotatably mounted to the inner wall of the lifting frame is installed at the output end of the motor. A nut is threaded onto the outer wall of the screw rod. A travel plate is installed at one end of the nut. An adjusting hydraulic rod is installed inside the travel plate. An installation plate is installed at the lower end of the adjusting hydraulic rod, and a scraper is installed at the lower end of the installation plate.

[0007] Furthermore, a sliding sleeve is provided at one end of the travel plate, and a guide rod that is slidably inserted into the sliding sleeve is provided inside the front side of the lifting frame;

[0008] Specifically, the travel plate slides on the outer wall of the guide rod via a sliding sleeve, which provides sliding guidance as the travel plate moves, ensuring stable movement.

[0009] Furthermore, positioning posts are provided at all four corners of the positioning frame, an assembly groove is provided at the lower end of the positioning frame, and an embedding groove is provided on the inner wall of the opening at the upper end of the positioning frame.

[0010] Specifically, the positioning posts position the four corners of the positioning frame, the display screen is placed and fixed through the assembly slot, the embedding slot is used to place the capacitive touch film body, and achieves automatic docking with the display screen. The isolation film of the capacitive touch film body is torn off so that the adhesive of the capacitive touch film body aligns with the display screen.

[0011] Furthermore, one end of the pressure strip is rotatably mounted with rubber rollers that are evenly distributed and adhere to the outer wall of the capacitive touch film body, one end of the pressure strip is provided with a guide rail, and the telescopic end of the adjusting hydraulic rod is provided with a slider that is slidably mounted with the guide rail;

[0012] Specifically, the pressure strip slides inside the slider via a guide rod, and the capacitive touch film body is flexibly supported by a rubber roller.

[0013] Furthermore, a travel groove is provided inside the upper end of the positioning frame, and the travel path of the pressure strip corresponds to the travel groove;

[0014] Specifically, when the scraper moves, it applies pressure to the pressure strip. When the pressure strip moves, it effectively passes through the positioning frame via the stroke groove. The rubber roller makes rolling contact with the outer wall of the capacitive touch film body, avoiding scratches on the outer wall of the capacitive touch film body. This allows the pressed capacitive touch film body segment to contact and be positioned. The positioning structure moves with the scraper.

[0015] Furthermore, a viewing window is embedded at one end of the lifting frame, and a pressure gauge is installed inside the upper end of the lifting frame;

[0016] Specifically, the inside of the lifting frame can be viewed through the viewing window, and the pressure inside the lifting frame can be understood through the pressure gauge.

[0017] Furthermore, a UV curing machine is installed inside the upper end of the lifting frame, and a frame-shaped sealing gasket corresponding to the pressing frame is installed on the upper end of the processing table;

[0018] Specifically, the UV curing machine can quickly cure the adhesive, improving installation efficiency; the sealing gasket provides a good sealing effect, improving the sealing performance at the joint between the lifting frame and the processing table.

[0019] Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] This invention requires a display screen with a capacitive touch film body to be installed. The screen is placed in the mounting slot at the lower end of a positioning frame, with the mounting surface facing upwards. After the adhesive release film is removed from the capacitive touch film body, it is placed on the mounting surface of the display screen. During this process, the lifting frame descends, and a negative pressure pump operates, drawing air from inside the lifting frame to create a vacuum. This prevents external contaminants from contacting the mounting structure of the capacitive touch film body. The linear travel of the screw and nut drives the travel plate to move, causing the pressure plate to press against the upper end of the capacitive touch film body. The entire capacitive touch film body is evenly pressed, and the air squeezed out inside the capacitive touch film body is quickly discharged, preventing the formation of air bubbles inside the capacitive touch film body. This improves the quality of the assembled capacitive touch film body and avoids problems such as uneven surface of the touch film caused by air bubbles, which affect the product's aesthetics, stress concentration, and reduced operational sensitivity.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
