Adhesive heating and temperature control device used in accelerometer assembling process

Abstract

The invention provides an adhesive heating and temperature control device used in the accelerometer assembling process. The adhesive heating and temperature control device comprises a heat preservation mold, a heating device arranged in the heat preservation mold and used for evenly heating adhesive between a meter shell and a meter core in the accelerometer assembling process, and a control device connected with the heating device and used for controlling heating temperature and heating time in the heating process. Due to the fact that the adhesive between the meter shell and the meter core is evenly heated in the accelerometer assembling process, the adhesive of a single accelerometer is evenly heated in the solidification process, and the service life of the accelerometer is prolonged; heat is preserved through the heat preservation mold, the heating temperature and the heating time can be controlled through the control device in the heating process, the heating temperature and the heating time for solidification of the adhesive on meter heads of the accelerometers of the same batch are the same, and the accelerometers of the same batch are prevented from being different.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to an adhesive heating temperature control device in an accelerometer assembly process. Background technique [0002] The head of the quartz flexible accelerometer is assembled by the watch core and the watch case, and the watch core is suspended and fixed in the cavity of the watch case by means of an adhesive ring-coated on the inner wall of the watch case. In the process of curing the ring-shaped adhesive between the watch core and the watch case, the ideal state is that the ring-coated adhesive of a single accelerometer head is heated evenly, and the same batch of accelerometer head adhesive is cured at the same heating temperature and heating time. However, in the actual production process, the temperature distribution inside the oven is not uniform, especially when multiple accelerometers are heated through the same oven, the temperature difference between differen...

AI Technical Summary

Problems solved by technology

However, in the actual production process, the temperature distribution inside the oven is not uniform, especially when multiple accelerometers are heated through the same oven, the temperature difference between the heads of different accelerometers can even reach tens of degrees Celsius

This temperature difference directly affects the curing rate of the adhesive applied between the watch movement and the case, resulting in differences in the degree of curing of the adhesive bonding the watch movement and the case of the same batch of watch heads; even for a single watch head, the adhesive Uneven heating during the curing process will lead to uneven distribution of bonding stress between the accelerometer core and the shell, causing acceleration measurement errors; as time goes by, uneven stress at the bonding site can accelerate bonding failure and reduce the accelerometer. service life
