AI Technical Summary

Technical Problem

When existing disconnection detection devices detect surface disconnection and no bottom line output, false alarms or complex mechanisms are prone to occur, and it is difficult for operators to accurately judge the disconnection situation.

Method used

By providing a detection device on the bra back buckle machine, the device includes a sensor body and an indicator light, the induction end is used to detect the friction force when the surface thread passes through and the tension force of the surface thread to the sewing needle, and in combination with the control IC control the working status of the indicator light, the operator is prompted to be prompted to break the wire.

Benefits of technology

It realizes a quick and accurate judgment of whether the surface line is broken or there is no bottom line transmission, and prompts the operator through the working status of the indicator light to avoid false alarms and complex mechanisms, and improves the accuracy and efficiency of the sewing process.

Abstract

The utility model discloses a thread breakage detection device for a bra back buckle machine, which is arranged on the head of the bra back buckle machine outside a mounting seat for mounting a thread clamp, comprises a sensor body and an indicator light, the bottom end of the sensor body is connected with a support plate, one end of the support plate is connected with one end of the mounting seat, a protrusion is arranged on the top of the sensor body, a limiting groove is arranged in the middle of the protrusion, the sensor body is provided with a sensing end which is located in the limiting groove and is used to detect the magnitude of friction force, a through hole is arranged in the middle of the sensing end for the surface thread to pass through, the indicator light is arranged on the surface of the sensor body outside the protrusion, a control IC and a processor which are connected with the indicator light and control the working state of the indicator light are arranged in the sensor body, the detection device judges whether the surface thread is broken or there is no bottom thread transmission by comparing the magnitude of friction force when passing through the sensing end and the magnitude of pulling force of the surface thread on the sewing needle, and controls the working state of the indicator light to give corresponding prompts according to the situation.
