Device for extracting bit codes of key

Abstract

The invention relates to a device for extracting bit codes of a key, which comprises a key clamp, a probing component, a signal output interface and a signal processing circuit. A probe base is arranged on the upper part of the key clamp; 6 to 10 cylindrical probe assemblies are arranged in a row vertically, and can slide along the longitudinal direction in the probe base; the probe assemblies comprise sampling probes and conductive probes which are connected by springs; the bottom of each sampling probe corresponds to a key accommodating groove; the bottom surface of each strain gauge base is in an arched shape; strain gauges are adhered to the arched surface; the top of each conductive probe corresponds to the arch crown of the bottom surface of the corresponding strain gauge base; two leads of each strain gauge are connected with the signal processing circuit through the signal output interface; and the signal processing circuit comprises an AD converter, a microprocessor, a CAN bus controller, a CAN bus transceiver and a meter amplifier. The device has the characteristics of high resolution ratio, sensitive response and good linearity, and can extract the bit codes of the key accurately.

Description

Technical field [0001] The invention belongs to the technical field of lock equipment manufacturing, and relates to a device that uses strain gauges to extract key flick codes, and is mainly used for extracting key flick codes on automatic lock installation equipment production lines of various lock factories. technical background [0002] With the development of modern society, the degree of automation is getting higher and higher, and people generally require higher production efficiency. The domestic lock automatic assembly production line is still blank, and there is only a single automatic assembly line abroad, with single parameters and high prices. It is only suitable for large lock companies to produce certain types of locks. As the first station of the production line of automatic locking equipment, the extraction of key tooth flower coding is directly related to the success of the lock body assembly. Summary of the invention [0003] The purpose of the present invention...
