Problems solved by technology
[0004] For some extremely small optical components, such as optical lenses, it is difficult to realize the mechanical clamping method of ordinary clamps, and the optical lens is made of glass, and there is stress in the mechanical clamping, which is easy to be crushed, so most of them are clamped by vacuum adsorption. hold
[0005] However, although the vacuum adsorption scheme has many advantages compared with mechanical clamping, it also has the following disadvantages: First, the vacuum adsorption needs to be connected to the vacuum pump through the vacuum hole on the clamp through a pipeline, and the vacuum pump is often huge in size and takes up more space. operating space, and accompanied by a lot of noise, it is not very convenient to use
Second, the principle of vacuum generation is that the vacuum pump continuously pumps and exhausts to generate negative pressure. The cycle of pumping and exhausting will generate a certain frequency of vibration, which will be transmitted to the fixture through the vacuum pipeline, resulting in the fixture not being able to hold constant Holds the optical lens firmly, greatly compromising the efficiency and quality of optical coupling

The invention provides a clamp and an optical coupling mechanism, and the clamp comprises a clamp body, a magnet, and a magnetic sheet. A working end is formed at one end of the clamp body; a slidinggroove and a clamping groove are formed in the clamp body; the sliding groove extends to the working end of the clamp body; the magnet is arranged in the sliding groove in a sliding mode in the lengthdirection of the sliding groove. The clamping groove is located in the working end and communicated with or not communicated with the sliding groove; the magnet is close to or far away from the clamping groove in a sliding mode, and the magnetic sheet and the magnet are arranged in a split mode and can be attracted into the clamping groove under the action of a magnetic force. According to the clamp, the clamping of a micro optical element is achieved through the magnetic attraction effect, the technical problems existing in existing vacuum adsorption clamping are solved, and the clamp has the advantages of being simple, reliable, free of occupied space, free of noise and free of vibration.
Description
technical field [0001] The invention relates to the technical field of optical module packaging, in particular to a clamp and an optical coupling mechanism. Background technique [0002] At present, there are optical elements inside the optical module, which are the core components of the optical module. Optical components include lasers, optical lenses, optical prisms, optical fibers, etc., which are necessary components for optical transmission. [0003] Most of the assembly process of the optical components inside the optical module adopts the coupling method, that is, the optical components are fixed and fine-tuned through multi-directional differential axes and fixtures, and then glued or welded to a suitable position to achieve optical path alignment. [0004] For some extremely small optical components, such as optical lenses, it is difficult to realize the mechanical clamping method of ordinary clamps, and the optical lens is made of glass, and there is stress in th...
