Description

Technical Field

[0001] This invention relates to the field of infrared touch screen processing technology, specifically to a precision processing device for the sensing layer of an infrared touch screen. Background Technology

[0002] Infrared touchscreens are widely used in educational whiteboards, conference tablets, and industrial control consoles due to their advantages such as high light transmittance, drift-free touch, multi-touch support, and insensitivity to glass thickness. The core component of an infrared touchscreen is the infrared touch bezel, which integrates a high-density array of infrared emitters and receivers, achieving positioning by detecting light obstructions.

[0003] During the assembly of infrared touch frame, after the frame structure undergoes CNC machining, grinding and handling, cutting fluid, aluminum shavings, fingerprints and dust will remain on the surface and in the gaps. Existing cleaning methods mostly use manual wiping or simple soaking cleaning. Manual wiping is inefficient and inconsistent, and it is easy to miss tiny gaps. Traditional ultrasonic cleaning baskets are mostly general type and lack special fixation for long strip frame, which causes the frame to shake with the water flow during the cleaning process. This not only makes it easy to collide and cause scratches on the appearance, but also makes it difficult to ensure the neatness after cleaning, which is not conducive to subsequent automated loading and unloading. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: An infrared touch screen sensing layer precision machining device includes an ultrasonic cleaner, a connecting plate, and a low-pressure pure water sprayer mounted on the connecting plate.

[0009] Preferably, two anti-detachment plates are fixedly connected to the front side of the cleaning frame near the left and right sides. Each pair of adjacent anti-detachment plates are arranged symmetrically from top to bottom. Several locking blocks are fixedly connected to the corresponding side of the two anti-detachment plates. The locking blocks are arranged linearly from left to right. A circular plate is fixedly sleeved on the outside of the moving rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a special fixing mechanism, the present invention can independently or as a whole limit multiple infrared touch frame edges in the cleaning frame.

A clamping plate 19 and a second clamping plate 20 are engaged by adjacent toothed blocks 21. A moving rod 17 is hinged to the front side of the push plate 28. The front end of the moving rod 17 passes through the inner cavity of the cleaning frame 7. Two anti-detachment plates 24 are fixedly connected to the front side of the cleaning frame 7 near the left and right sides. Each pair of adjacent anti-detachment plates 24 are arranged symmetrically from top to bottom.

When the first clamping plate 19 and the second clamping plate 20 swing in opposite directions, the infrared touch frame 8 can be fixed. When the drive motor 14 is started, it can drive the two winding wheels 11 to rotate through the power output shaft. When the two winding wheels 11 rotate, it can drive the cleaning frame 7 to move upward through the pull rope 5.
