NTC temperature sensor insert production device and method

Abstract

The invention discloses an NTC temperature sensor insert plate production apparatus and belongs to the field of electronic sensor production. The NTC temperature sensor insert plate production apparatus comprises a fixing plate, a wire rod and core positioning tool and a wire rod and core shaping tool. The fixing plate is provided with a plurality of grooves in an interval manner. The wire rod and core positioning tool is provided with a plurality of bosses corresponding to the grooves. Two opposite angels of each boss are arranged in a chamfering manner. The width of each boss equals to the space between two cores of the same wire rod. The wire rod and core shaping tool is provided with open grooves. The top of each groove is arranged in a V-shaped manner. The width of each open groove equals to or is larger than the space between two cores of the same wire rod. The temperature sensor production is updated from previous one-by-one manual welding to equipment entire-frame welding, so that welding time and welding temperature are unified, and the product production efficiency is effectively improved. The welding speed is fast, the welding process is precisely controlled and the welding consistency is good, so that the qualified rate of finished products is greatly improved. The invention also discloses an NTC temperature sensor insert plate production method.

Description

technical field [0001] The invention relates to a production method of an NTC temperature sensor, specifically an NTC temperature sensor insert production device and method with high production efficiency and high product qualification rate, belonging to the field of electronic sensor production. Background technique [0002] It is a common production method of temperature sensors in the prior art to directly connect the NTC thermosensitive chip and the wire rod together by welding to make an NTC temperature sensor. In the current temperature sensor production process, the welding between the chip and the wire is usually done by manual welding. However, manual welding personnel need special training before they can work on the job. The professional requirements are high, the manual welding speed is slow, and the manufacturing efficiency is low. At the same time, the welding process is completely controlled by the operator, and the welding quality cannot be guaranteed. The qu...
