Description

Technical Field

[0001] The invention belongs to the technical field of gyroscope manufacturing, and in particular relates to a pin cutting device of an active device and a use method thereof. Background Art

[0002] In the prior art, gyroscopes are increasingly tending towards miniaturization, but the pin lengths of active devices such as waveguide devices with pins, 6-pin light source devices, 8-pin light source devices, 14-pin pump lasers, etc. are still at the standard length when leaving the factory, and no length change has been made. It should be noted that the active device includes an active device body, and both sides of the length direction of the active device body have optical fibers of preset lengths, and both sides of the short sides of the active device body have pins for connecting to the circuit board. However, the pin length of the active device needs to adapt to the spatial diversity and miniaturization trend of the gyroscope, so pin trimming must be performed.

[0003] The connection between the pin root of the active device and the tube shell is sealed with a glass insulator, which takes on the airtightness and insulation functions; the internal end of the light source pin of the active device is connected to the components in the tube shell with a metal wire or a semiconductor ball.

[0004] Currently, the pins of active devices are sheared by means of suspended shearing. During the shearing process, shear stress is easily introduced into the root of the pins of the active devices, and the stress is conducted into the pins. Although some pins are sheared by crimping, simulation shows that stress is still conducted into the pins during the stress conduction path. There is a risk of peeling and breaking between the glass insulator and the pins and the shell during the stress conduction process.

[0005] Current technical status of active device pin cutting: In different application scenarios, the pins of active devices have length variation requirements. First, the length needs to be marked on the pins, and then the excess pins need to be cut off at the marked points with flat-nosed pliers. This operation has defects: the pin length needs to be measured and marked once, and then cut with flat-nosed pliers. During the pin cutting process, shear stress is easily introduced at the pin root, and the stress is transmitted into the pin. During the stress transmission process, there is a risk of peeling and breaking between the glass insulator and the pins and the tube shell. Summary of the invention
