Description

Technical Field

[0001] This utility model relates to the field of touch screen glass plate processing technology, specifically to a feeding device for a touch screen glass plate coating machine. Background Technology

[0002] Touchscreen glass is a key component of electronic devices such as mobile phones and tablets. As the direct interface for user interaction, it features good light transmittance, high hardness, and a smooth surface, ensuring clear display and a smooth touch experience. During production, touchscreen glass undergoes multiple precision processing steps, with PE film lamination being a crucial one. The PE film not only prevents scratches and stains during subsequent processing and transportation but also maintains the optical stability of the glass surface.

[0003] In the existing technology, the PE film coating of touch screen glass mainly relies on two operation modes: (1) Pure manual operation mode: the operator holds the glass and places it one by one on the PE film, and completes the positioning by visually aligning with the edge marks. This mode has significant defects: first, the positioning accuracy of manual placement is greatly affected by the operator's skill level and fatigue; second, glass is a fragile item, and the edges and corners are easily damaged due to uneven force during manual handling; for example Figure 1 As shown, (2) introduces a mechanical conveyor line, but still requires manual positioning of the glass onto the conveyor line carrier.

[0004] In summary, on the one hand, labor costs account for as much as 40% of the total cost of the lamination process; on the other hand, PE film waste and glass loss caused by positioning deviations increase material costs by 20%-30%. Therefore, developing an automatic feeding and positioning device with high precision, self-adaptation, and fully closed-loop control has become an urgent need in the industry.

[0005] The applicant previously applied for a multi-purpose optical testing device (CN116858495A), which moves glass plates onto a turntable via a feeding assembly. Specifically, the suction cups on the feeding robot pick up the glass plates from the product tray and place them onto the turntable. Therefore, the applicant, combining this previously developed feeding robot, has created a fully automated feeding touchscreen glass plate coating machine. Utility Model Content

[0006] The present invention aims to provide a feeding device for a touch screen glass plate laminating machine, so as to provide a way to place the glass stably on the PE film by means of a robotic arm instead of manual labor.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding device for a touch screen glass plate laminating machine includes a laminating machine body and a robotic arm; the robotic arm is disposed on the feeding side of the laminating machine body and is used to grab the touch screen glass plate and transfer it to the laminating station; the robotic arm includes a robotic arm body and a vacuum adsorption component disposed at the end of the robotic arm body and used to adsorb the touch screen glass plate.

[0009] The working principle and beneficial effects of this utility model:

[0010] The robotic arm moves in space, thereby moving the vacuum adsorption component to the position where the touch screen glass plate is placed. The vacuum adsorption component uses the negative pressure generated by the vacuum pump to firmly adsorb the touch screen glass plate. Then the robotic arm moves the adsorbed touch screen glass plate to the laminating station of the laminating machine.

[0011] The use of robotic arms enables the automatic gripping and transfer of touch screen glass panels from the feeding side to the lamination station. Compared with manual operation, this greatly improves production efficiency and reduces labor costs. At the same time, the robotic arms have relatively high motion precision, which can effectively reduce glass damage caused by manual handling and improve the product yield.

[0012] Preferably, the vacuum adsorption assembly includes multiple vacuum suction cups. Under the action of a vacuum pump, each vacuum suction cup generates negative pressure in its respective adsorption area. When the vacuum adsorption assembly moves above and adheres to the touchscreen glass panel, the multiple vacuum suction cups simultaneously adsorb onto the surface of the touchscreen glass panel, dispersing the adsorption force and ensuring stable adsorption of the glass.

[0013] Preferably, the device also includes a glass frame for use with a robotic arm, wherein multiple touchscreen glass panels are placed facing the vacuum suction cup. The multiple touchscreen glass panels are fixed in position on the glass frame and are positioned facing the vacuum suction cup. When the robotic arm receives a gripping command, it moves the vacuum suction component above the glass frame. The vacuum suction component adsorbs the touchscreen glass panels facing the vacuum suction cup on the glass frame, and then the robotic arm transfers them to the lamination station.

[0014] Preferably, the robotic arm body includes a body and an operating arm. The body is fixedly equipped with a first motor that drives the operating arm to rotate. The operating arm is fixedly equipped with a cylinder. The movable end of the cylinder is fixedly equipped with a connecting arm. The connecting arm is fixedly equipped with a second motor. The movable end of the second motor is fixedly equipped with a rotating arm. The rotating arm is fixedly equipped with a third motor. The movable end of the third motor is fixedly equipped with a rotating platform. The vacuum suction cup is fixedly installed on the rotating platform.

[0015] The first motor drives the operating arm to rotate, allowing the robotic arm to adjust its angle in the horizontal direction and expand its working range; the cylinder, through its telescopic movement, drives the connecting arm to rise and fall in the vertical direction, enabling the vacuum adsorption component to adapt to the gripping of touch screen glass panels of different heights; the second motor drives the rotating arm to rotate, which can further adjust the angle of the vacuum adsorption component in the horizontal direction; the third motor drives the rotating table to rotate, enabling the vacuum suction cup to make fine-tuning adjustments to its angle, so as to better adjust the posture of the touch screen glass panel during gripping and transfer, and make it accurately reach the lamination station.

[0016] Optimized, the vacuum suction cups are symmetrically arranged along the axis of the rotating stage. This symmetrical arrangement ensures the suction force generated by the symmetrically distributed suction cups guarantees the stability of the glass during rotation, preventing it from shifting or falling due to uneven force.

[0021] The following detailed description illustrates the specific implementation method:

[0022] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0023] Example: Figure 2 and Figure 3 As shown, a feeding device for a touch screen glass plate laminating machine includes a laminating machine body and a robotic arm; the robotic arm is set on the feeding side of the laminating machine body and is used to grab touch screen glass plates and transfer them to the laminating station; it also includes a glass frame used in conjunction with the robotic arm, and the glass frame holds multiple touch screen glass plates that are directly opposite the vacuum suction cup 10.

[0024] The robotic arm includes a body 3 and an operating arm 8. The body 3 is fixedly equipped with a first motor 9 that drives the operating arm 8 to rotate. The operating arm 8 is fixedly equipped with a cylinder 7. The movable end of the cylinder 7 is fixedly equipped with a connecting arm 6. The connecting arm 6 is fixedly equipped with a second motor 5. The movable end of the second motor 5 is fixedly equipped with a rotating arm 4. The rotating arm 4 is fixedly equipped with a third motor 1. The movable end of the third motor 1 is fixedly equipped with a rotating platform 2. A vacuum suction cup 10 is fixedly installed on the rotating platform 2. The vacuum suction cup 10 generates negative pressure through a vacuum pump connected to a flexible pipe.

[0025] The third motor 1 drives the rotating platform 2 to rotate, allowing the vacuum suction cup 10 to be finely adjusted so that it faces the touchscreen glass panel. The second motor 5 drives the rotating arm 4 to rotate toward the touchscreen glass panel, causing the rotating platform 2 and the vacuum suction cup 10 to rotate toward the touchscreen glass panel. The vacuum suction cup 10 adheres to the touchscreen glass panel, and the vacuum pump draws air outward to generate suction force from the vacuum suction cup 10. The cylinder 7, through its extension and retraction movement, drives the connecting arm 6, the rotating arm 4, the rotating platform 2, and the touchscreen glass panel to rise vertically, causing the touchscreen... The touchscreen glass panel detaches from the glass holder, and then the first motor 9 drives the operating arm 8 to rotate, moving the connecting arm 6, rotating arm 4, touchscreen glass panel, etc., to the lamination station. Then, the third motor 1 drives the rotating table 2 to rotate, and the vacuum suction cup 10 adsorbs the touchscreen glass panel and rotates it to face the lamination station. The cylinder 7 moves the touchscreen glass panel downwards above the lamination station through its telescopic movement. The vacuum pump stops working, and the vacuum suction cup 10 no longer generates suction to adsorb the touchscreen glass panel. The touchscreen glass panel automatically falls to the lamination station for lamination.

[0026] The robotic arm and the laminating machine body described above are existing technologies. For ease of understanding, the above structural components have been supplemented. However, the improvement of this application is not the robotic arm or the laminating machine body, but rather the combination of the two together.

The specific connection methods of each part adopt conventional methods such as screws, rivets, and welding that are mature in the prior art.
