Description

Technical Field

[0001] This utility model belongs to the field of optical device adhesive application technology, and in particular relates to an optical device adhesive application device. Background Technology

[0002] After the active and passive components of an optical device are focused and coupled, they are often fixed with UV adhesive. However, relying solely on UV adhesive for fastening results in poor bonding stability and low bond strength, especially under long-term use or mechanical stress. This can easily lead to poor contact or even detachment of the device during use. To ensure the stability and strength of the bonding between optical device components, additional adhesive needs to be applied at the joints to make the optical device more secure.

[0003] Comparing this to Chinese Patent Publication No. CN 216655188 U, a multifunctional optical device adhesive application device is disclosed, comprising a base plate, a fixing seat fixedly connected to the top of the base plate, an optical device disposed on the top of the fixing seat, a clamping and fixing mechanism disposed on the top of the fixing seat, a vertical plate fixedly connected to the rear side of the top of the base plate, a horizontal plate slidably connected to the front side of the vertical plate, and a lifting mechanism disposed between the vertical plate and the horizontal plate; the clamping and fixing mechanism includes mounting seats fixedly connected to the left and right sides of the top of the fixing seat, each mounting seat having a first threaded rod threadedly connected to its opposite side, the opposite ends of the two first threaded rods penetrating the fixing seat and extending to the outside of the fixing seat. This utility model relates to the field of optical device adhesive application technology. This multifunctional optical device adhesive application device, through the setting of the clamping and fixing mechanism, achieves rapid clamping and fixing of optical devices of different sizes, thereby improving adhesive application efficiency.

[0004] The disadvantages of the above patent are: during the processing, the adhesive will gradually cool and solidify while waiting for the optical device to be reloaded, making it difficult to remove again and easily causing the adhesive to string between the device and the device; the optical device is fixed by clamping, which makes it impossible to precisely control the clamping force, and too much force will damage the optical device.
