Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screen processing technology, and in particular to a bonding device for capacitive touch screen processing. Background Technology

[0002] In the manufacturing process of capacitive touchscreens, the bonding process is one of the core steps. It involves precisely aligning and tightly bonding the cover plate and function board to form a complete touch structure. The precision of this process directly affects the touch sensitivity, display effect, and lifespan of the touchscreen. Currently, the bonding methods commonly used in the industry mostly rely on manual positioning or simple mechanical structures. The positioning of the cover plate and function board mainly depends on the operator's visual observation, and there is a lack of stable fixing and guiding mechanisms during the bonding process.

[0003] Capacitive touchscreens have several shortcomings during the bonding process and in use: Manual positioning is prone to errors, resulting in misalignment between the cover plate and the functional plate, which affects the product qualification rate. Traditional devices lack a reliable adsorption and fixing structure, and the cover plate is prone to shifting or shaking during bonding. Furthermore, the stability is poor during the flipping process, which can easily damage the plate. Meanwhile, the horizontal movement and vertical lifting mechanisms lack operational precision, are prone to jamming during movement, cannot achieve precise docking between the cover plate and the functional plate, and require high manual intervention, resulting in low production efficiency and difficulty in meeting the needs of mass production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bonding device for capacitive touch screen processing, which overcomes the deficiencies of existing technologies and effectively solves the problems of low positioning accuracy, unstable fixation, sluggish operation, and low production efficiency of traditional bonding devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bonding device for processing capacitive touch screens includes a base frame. Symmetrically distributed gantry frames are fixedly connected to the top outer wall of the base frame by screws, and a rotating tube is installed through two gantry frames. A flipping table is fixedly connected to the top outer wall of the rotating tube by screws. A stepper motor is fixedly connected to one side outer wall of one of the gantry frames by screws, and a pulley pair is installed between the stepper motor and the rotating tube. A horizontal cylinder is fixedly connected to the top outer wall of the base frame by screws, and a transverse stage is fixedly connected to the piston rod of the horizontal cylinder. A vertical cylinder is fixedly connected to the bottom outer wall of the transverse stage by screws, and a lifting plate is fixedly connected to the piston rod of the vertical cylinder.

[0006] Preferably, both the top outer wall of the tilting table and the lifting plate are provided with L-shaped positioning strips, and the tilting table is provided with a cover plate via the L-shaped positioning strips, while the lifting plate is provided with a functional plate via the L-shaped positioning strips.

[0007] Preferably, the end of the rotating tube away from the pulley pair is rotatably connected to an air extraction pipe via a rotary joint, and an air suction pipe is provided between the air extraction pipe and the tilting table.

[0008] Preferably, the bottom outer wall of the transverse platform is provided with symmetrically distributed sliders, and the top outer wall of the base frame is fixedly connected with a slide rail by screws, and the sliders slide in cooperation with the slide rail.

[0009] Preferably, a control switch is provided on one side of the top outer wall of the base frame, and the control switch is connected to both the horizontal cylinder and the vertical cylinder via electrical signals.

[0010] Preferably, the bottom inner wall of the base frame is provided with a sliding groove, and the vertical cylinder is disposed inside the sliding groove.

[0014] 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.

[0015] Reference Figures 1-4 Example 1: A bonding device for processing a capacitive touch screen includes a base frame 1. The top outer wall of the base frame 1 is fixedly connected to symmetrically distributed gantry frames 2 by screws, and a rotating tube 3 is installed through the two gantry frames 2. The top outer wall of the rotating tube 3 is fixedly connected to a flip table 4 by screws. One side outer wall of one of the gantry frames 2 is fixedly connected to a stepper motor 5 by screws, and a pulley pair 6 is installed between the stepper motor 5 and the rotating tube 3.

[0016] Through the above scheme, the base frame 1 serves as the supporting foundation of the entire device, providing a stable installation platform for each component and ensuring the overall stability of the device during operation; the gantry frame 2 is symmetrically distributed on the top of the base frame 1, serving to support the rotating tube 3 and ensuring that the rotating tube 3 can rotate flexibly; the stepper motor 5 adopts the 57HS22 model, which works by receiving pulse signals to achieve precise stepping rotation, and transmits power to the rotating tube 3 through the pulley pair 6, driving the flipping table 4 to perform precise flipping from 0 to 180 degrees, meeting the requirements of cover plate flipping and fitting. Compared with ordinary motors, the stepper motor 5 has higher positioning accuracy and can effectively ensure the accuracy of the flipping angle.

[0017] In embodiment 2, a horizontal cylinder 7 is fixedly connected to the top outer wall of the base frame 1 by screws, and a horizontal moving platform 8 is fixedly connected to the piston rod of the horizontal cylinder 7. A vertical cylinder 9 is fixedly connected to the bottom outer wall of the horizontal moving platform 8 by screws, and a lifting plate 10 is fixedly connected to the piston rod of the vertical cylinder 9.

[0018] According to the above scheme, the horizontal cylinder 7 is selected as model SC63-200, which works by pneumatically driving the piston rod to extend and retract, thereby moving the horizontal moving platform 8 in the horizontal direction to realize the horizontal position adjustment of the functional plate; the vertical cylinder 9 is selected as model SC40-100, which also uses pneumatically driven piston rod extension and retraction to drive the lifting plate 10 to vertically lift and lower, thus completing the fitting action between the functional plate and the cover plate; the horizontal moving platform 8 serves as the mounting carrier for the vertical cylinder 9, ensuring the stable installation of the vertical cylinder 9; the lifting plate 10 is used to place the functional plate, and it works in conjunction with the flipping platform 4 to realize the vertical alignment of the cover plate and the functional plate. The two cylinders work together to achieve precise displacement of the functional plate and improve the fitting accuracy.

[0019] Both the top outer wall of the tilting table 4 and the lifting plate 10 are provided with L-shaped positioning strips 11, and the tilting table 4 is provided with a cover plate through the L-shaped positioning strips 11, and the lifting plate 10 is provided with a functional plate through the L-shaped positioning strips 11.

[0020] With the above solution, the L-shaped positioning strips 11 are fixed to the top outer walls of the flipping table 4 and the lifting plate 10 respectively. Their shape is adapted to the edge contours of the cover plate and the functional plate, which can limit the cover plate and the functional plate, prevent displacement during placement, and achieve initial accurate positioning. The cover plate is placed in the area enclosed by the L-shaped positioning strips 11 of the flipping table 4, and the functional plate is placed in the area enclosed by the L-shaped positioning strips 11 of the lifting plate 10, ensuring that the two always maintain the initial positioning state during subsequent movement and flipping, laying the foundation for subsequent accurate fitting.

[0021] The end of the rotating tube 3 away from the pulley pair 6 is rotatably connected to the suction pipe 12 via a rotary joint, and an air suction pipe 13 is provided between the suction pipe 12 and the tilting table 4.

[0022] With the above scheme, the suction pipe 12 is connected to the rotating pipe 3 through a rotary joint. The rotary joint ensures that the suction pipe 12 remains fixed when the rotating pipe 3 rotates, avoiding pipe entanglement. The suction pipe 12 is connected to a vacuum pump. When working, the vacuum pump starts and generates an adsorption force on the cover plate on the flipping table 4 through the suction pipe 13, which firmly fixes the cover plate on the flipping table 4 and prevents the cover plate from slipping or shifting during the flipping process. The suction pipes 13 are evenly distributed at the bottom of the flipping table 4 to ensure that the adsorption force is evenly distributed, avoiding deformation of the cover plate due to uneven force, and further ensuring the bonding quality.

[0023] The bottom outer wall of the transverse stage 8 is provided with symmetrically distributed sliders 14, and the top outer wall of the base frame 1 is fixedly connected with a slide rail 15 by screws, and the sliders 14 and the slide rail 15 slide in cooperation.

[0024] With the above scheme, the slider 14 is symmetrically installed at the bottom of the transverse stage 8, and the slide rail 15 is fixed to the top of the base frame 1 and adapted to the slider 14. The two constitute a sliding guide mechanism. When the horizontal cylinder 7 drives the transverse stage 8 to move, the slider 14 slides along the slide rail 15 to provide guidance and support for the movement of the transverse stage 8, reduce the friction during the movement, make the transverse stage 8 run more smoothly and stably, and avoid jamming. At the same time, the sliding fit structure can ensure the movement accuracy of the transverse stage 8, ensure that the functional plate can be accurately moved to the bottom of the cover plate, and improve the fitting and alignment accuracy.

[0025] A control switch 16 is provided on one side of the top outer wall of the base frame 1, and the control switch 16 is connected to the horizontal cylinder 7 and the vertical cylinder 9 by electrical signals.

[0026] Through the above scheme, the control switch 16 is a centralized control component, adopting a button design, which corresponds to the extension and retraction of the horizontal cylinder 7, the lifting and lowering of the vertical cylinder 9, and the start, stop, and reverse functions of the stepper motor 5. The operator sends an electrical signal by pressing the control switch 16 to control each component to run according to the preset program, realizing automated bonding operation. The electrical signal connection method between the control switch 16 and each electrical component ensures a rapid response to control commands, improves the convenience of operation, avoids the randomness of manual operation, and ensures the consistency and stability of each bonding process.

[0027] The bottom inner wall of the base frame 1 is provided with a sliding groove, and the vertical cylinder 9 is installed inside the sliding groove.

[0028] Through the above scheme, the sliding groove at the bottom of the base frame 1 provides installation and movement space for the vertical cylinder 9, ensuring that the vertical cylinder 9 can move horizontally synchronously with the transverse platform 8, avoiding the limitation of the movement stroke of the transverse platform 8 due to the installation position of the vertical cylinder 9; the inner wall of the sliding groove is smoothed to reduce the frictional resistance when the vertical cylinder 9 moves, and at the same time, it plays a limiting role for the vertical cylinder 9 to prevent it from deviating when moving, ensuring the running accuracy of the vertical cylinder 9, thereby ensuring that the lifting plate 10 can be accurately raised and lowered, and achieving precise fitting between the functional plate and the cover plate.

[0029] Working principle: The operation process of this device is mainly divided into four stages: positioning and placement, flipping preparation, precise displacement and bonding completion.

[0030] First, the operator places the cover plate on the tilting table 4 and completes the initial positioning by using the L-shaped positioning strip 11. At the same time, the function plate is placed in the L-shaped positioning strip 11 of the lifting plate 10 for positioning. Then, the vacuum pump is started, and the cover plate is adsorbed and fixed by the air extraction pipe 12 and the air suction pipe 13 to prevent it from shifting during tilting.

[0031] Next, the stepper motor 5 is started by the control switch 16. The stepper motor 5 drives the rotating tube 3 to rotate through the pulley pair 6, causing the tilting table 4 to rotate 180 degrees, so that the cover plate faces downward and aligns with the functional panel area below. After that, the horizontal cylinder 7 is started by the operation of the control switch 16. The horizontal cylinder 7 drives the transverse table 8 to move horizontally along the slide rail 15 through the slider 14, precisely moving the lifting plate 10 carrying the functional panel directly below the cover plate. Finally, the vertical cylinder 9 is activated, which drives the lifting plate 10 to move up and down, so that the function board and the cover plate are tightly attached. After the attachment is completed, the vacuum pump is turned off, the stepper motor 5 is started in reverse to reset the flipping table 4, and then the horizontal cylinder 7 and the vertical cylinder 9 are reset by the control switch 16. The attached capacitive touch screen is then taken out, completing the entire attachment process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
