Embodiment Construction

[0107] Such as Figure 1-4 As shown, a glass-encapsulated temperature sensor includes a chip 1, and a wire 2 is fixed on the left and right sides of the chip 1 by silver paste welding. The wire 2 is a dumet wire, and the diameter of the dumet wire is 0.3m / m. The ends of the chip 1 and the wire 2 are covered with a glass tube 3, and the glass tube 3 is integrated with the chip 1 and the wire 2 after heat melting.

[0108] A glass-encapsulated temperature sensor is processed and manufactured with special equipment. Specifically, the equipment includes a conveying platform 1, on which, from left to rear, there are successively a transfer fixture lowering mechanism 2, a straightening and shearing mechanism 3, a silver dipping mechanism 4, a chip welding mechanism 5, and a silver drying mechanism 6. , Insert glass bulb mechanism 7 and glass sealing forming mechanism 8. The above mechanisms respectively complete Dumet silk thread straightening --> Straightening --> Clamping wire -...

Abstract

The invention discloses a glass package temperature sensor and a manufacturing method thereof. The glass package temperature sensor which is formed by wrapping and fusing glass bulb is made through the steps of wire straightening, straightening, clamping pulling line, cutting, jig transfer, trimming, silver staining, bonding sheet, preheating, silver baking, inserting and sleeving glass tube, pre-heating, high temperature molding, overturning, preheating, high temperature molding and material receiving. According to theglass package temperature sensor and the manufacturing method thereof, theworking efficiencycan be improvedwhen processing is carried out in a reasonable manner.

Description

technical field [0001] The invention relates to the production field of a glass-encapsulated temperature sensor, in particular to a glass-encapsulated temperature sensor and a manufacturing method thereof. Background technique [0002] In the production process of the glass-encapsulated temperature sensor, the following process needs to go through: wire straightening --> straightening --> clamping wire --> cutting --> jig transfer --> cutting --> dipping silver --> Sticking film-->preheating-->baking silver-->inserting glass tube-->preheating-->high temperature forming-->turning over-->preheating-->high temperature forming-->receiving. [0003] The wire pins used in the glass-encapsulated temperature sensor are Dumet wires, and the diameter of the Dumet wires is less than 0.3m / m. The Dumet wires are nickel-iron alloys with copper plating and are generally used in the diode or light bulb (tube) industry. Because the wire is a n...
