Description

Technical Field

[0001] This invention specifically relates to a precision optical dispensing and bonding device, belonging to the field of optical component processing technology. Background Technology

[0002] Optical lenses are typically lens groups composed of several lens elements, which are connected by a cementing process. The cementing process for optical lenses refers to the process of bonding two or more lenses or plane mirrors together using optical adhesive or photoresist, according to specific technical requirements, to form an optical component. In actual production, cementing has two technical requirements: first, to ensure center or angular error; and second, to ensure "zero-defect" cementing, meaning that the polished surface of the cemented surface does not suffer a reduction in surface defect requirements due to cementing, and that the surface shape of the non-cemented surfaces is not affected by the cementing process.

[0003] In existing telescopes or microscopes, prism assemblies utilize optical lenses stacked in a 45° step configuration to achieve specialized optical systems. For example, a 45° tilt design allows the lens group to refract or reflect light at specific angles, converting direct light into oblique light, or adjusting the imaging path to suit different observation needs. In microscopes and similar equipment, 45° step lens combinations can reduce aberrations (such as spherical aberration and coma), improving image clarity and contrast. In astronomical telescopes, this structure is often used in upright imaging systems to convert inverted images to upright ones, or to adjust the observation angle (such as 45° tilted observation).

[0004] Current optical component bonding processes typically involve bonding only two lenses, or at most three. When bonding multiple lenses, it's impossible to guarantee their parallelism or achieve a 45° stepped stacking structure in a single operation, thus impacting production efficiency and product quality. Therefore, to address these issues, a precision optical dispensing and bonding device is urgently needed. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a precision optical dispensing and bonding device capable of processing multiple lenses into a 45° stepped stacked structure. This device is easy to operate and effectively ensures product quality.

The manual dispensing device consists of a glue cartridge and a dispensing needle. The dispensing needle is fixed to the bottom of the glue cartridge. In use, the operator places the pressing fixture onto the dispensing platform, places the protective sheet and the product on the pressing fixture, and performs the dispensing operation manually as needed, observing and evaluating the effect. Simultaneously, to ensure dispensing quality, the glue cartridge can be electrically connected to the dispensing controller, and the dispensing controller can be communicatively connected to the control panel. The dispensing volume is set via the control panel, and the dispensing controller controls the dispensing and jogging of the glue cartridge, ensuring uniform glue application to the product.

The pressure sensor detects the pressure signal in real time and transmits the pressure signal to the control panel for analysis and processing, comparing it with the preset pressure value. After the preset pressing time is reached, the telescopic rod of the lifting cylinder is controlled to retract, causing the pressing block to separate from the stacked adhesive blocks.
