Abstract

The invention provides a sewing thread position detection device and a sewing thread position detection method. The sewing thread position detection device comprises a first electrode unit, a second electrode unit and a capacitance detection unit, wherein the first electrode unit is overhung on a transversely-conveyed sewing thread, the second electrode unit is arranged below the first electrode unit correspondingly, a capacitive device is formed between the first electrode unit and the second electrode unit, and the capacitance detection unit electrically connected to the capacitive device is used for detecting capacitance changes of the capacitive device, and outputting electric trigger signals when the capacitance is changed to reach a preset reference value. The sewing thread position detection device and the sewing thread position detection method have the advantages that capacitive remote touch induction is adopted, breakage of an upper thread can be judged effectively, looseness degree of the upper thread can be detected effectively, and high flexibility and simple structure are achieved. .

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a sewing thread position detection device and method. Background technique [0002] When the sewing machine is working, the bottom thread and the upper thread interweave to complete the sewing action. Usually, the bottom thread is relatively "firm" and difficult to break, but the upper thread is more prone to "broken thread". The thread breakage detection of sewing machines on the market now uses switch-type metal contacts. Although this design is simple in structure, it will cause mechanical wear and tear due to long-term collisions, and the accuracy of the test is also relatively slow. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a sewing thread position detection device and method to solve the problem in the prior art that the switch-type metal contact detection of broken th...
