The present invention discloses an optical fiber connection structure and a phacovitrectomy machine. The optical fiber connection structure includes a connection seat, a connector and an elastic member. A sleeve is provided on the connection seat, and a first optical fiber is passed through the connection seat; the connector includes an optical fiber tube and a locking assembly sleeved on the optical fiber tube, and a second optical fiber is passed through the optical fiber tube, and the locking assembly and the sleeve are detachably connected; the elastic member is provided between the connector and the connection seat. In the optical fiber connection structure provided by the present invention, the optical fiber tube is inserted into the sleeve, and the locking assembly and the sleeve are connected. The locking assembly squeezes the elastic member and contacts and conducts with the elastic member, and the optical fiber tube abuts and conducts with the connection seat. When the elastic member is connected to the signal circuit, the electrical signal sent by the signal circuit is sequentially transmitted to the connection seat through the elastic member, the locking assembly and the optical fiber tube, and the connection seat has an electrical signal.

The optical module disclosed herein includes a circuit board, a substrate, a laser, an optical modulation chip, and a fiber array. The substrate surface is prone to rusting; therefore, a protective layer can be formed on the substrate surface. A first connecting plate is provided between the substrate and the fiber array. A first thermosetting interface layer is formed between the bottom surface of the first connecting plate and the protective layer, and a first photocurable interface layer is formed between the top surface of the first connecting plate and the fiber array. The first thermosetting interface layer increases the interfacial bonding energy between the protective layer and the first connecting plate, thereby increasing the adhesion between the substrate and the first connecting plate. The first photocurable interface layer is formed by low-temperature curing, thereby preventing the fiber array from deforming due to high temperatures. The first photocurable interface layer has a low shrinkage rate, preventing the fiber array from deforming due to stress, thereby reducing the optical path offset of the fiber array. The bottom and top surfaces of the first connecting plate form different interface layers, satisfying both the adhesion between the connecting plate and the protective layer and ensuring that the fiber array has a low optical path offset.

This utility model provides a fiber optic thermal printer for detecting label gaps, including a base, a cover, a core, a rubber roller, and a thermal sheet. The core has a receiver installed in a mounting groove and a transmitter installed outside the groove. The cover has a U-shaped light guide groove containing a fiber optic cable. The rubber roller is located in the mounting groove and adjacent to the thermal sheet. The thermal sheet and rubber roller face each other, forming a paper path. The paper path passes through the mounting groove. The light outlet is located inside the mounting groove, and the light inlet is located outside. The transmitter faces the light inlet, and the light outlet faces the receiver. In this invention, the detection light first bypasses the paper in the paper path, and then passes through the paper only once to detect edges and gaps, significantly reducing light loss and improving detection stability and print quality.

The utility model discloses a laser module and an optical fiber illumination system, and belongs to the technical field of optical fiber illumination. The laser module comprises a tube shell, a coupling lens, a connecting tube and a tail fiber assembly, the coupling lens is installed on the tube shell, the tube shell is used for installing a laser, and the coupling lens is used for coupling laser emitted by the laser into the tail fiber assembly. The end, close to the coupling lens, of the connecting pipe is arranged on the pipe shell in a sleeving mode, and the end, away from the coupling lens, of the connecting pipe is arranged on the tail fiber assembly in a sleeving mode. Through the design of the tube shell, the laser, the coupling lens, the connecting tube and other coupling elements are sequentially installed on the tube shell, and the installation precision and the final coupling efficiency of the coupling elements are guaranteed.
