Embodiment 1

[0027] see figure 1 and figure 2 , a laser bonding temperature collection system for optoelectronic device packaging, including a temperature sensor and its positioning member, different temperature sensors are respectively arranged around the periphery of the glass substrate 10 used for optoelectronic device packaging, the temperature sensor can be set by the positioning member The position of the temperature collection point, so that different temperature sensors are arranged along the glass sealing strip 11 used for optoelectronic device packaging to carry out the temperature collection point layout, and the corresponding positions of the glass sealing strip 11 are respectively used for fixed-point temperature measurement, and the glass substrate 10 is fixedly installed on the support base plate 1, and there is an annular reserved gap between the outer edge of the glass substrate 10 and the notch edge of the positioning groove 2, and the positioning member is arranged in t...

Embodiment 2

[0039] The technical solution of this embodiment is basically the same as that of Embodiment 1, especially in that:

[0040] see Figure 4 , In this embodiment, an indicating scale 5 is also provided near the slideway 4, and the indicating scale 5 measures the current position of the indicating slide body on the slideway 4, and accurately positions the temperature sensor installed on the slideway. The indicator scale 5 of the sliding member can provide precise scales to facilitate precise positioning of the movement coordinates of the sliding body, thereby realizing more precise adjustment and positioning of the temperature sensor, and can accurately measure the temperature of different points of the glass sealing strip 11 .

Abstract

The invention discloses a laser bonding temperature acquisition system for optoelectronic device packaging, which includes a temperature sensor and its positioning member. The positioning member includes a fixed position positioning member and a variable position positioning member. The fixed position positioning member is used for fixed-point temperature measurement. The temperature sensor is fixed at the corresponding position of the glass sealing strip, and the fixed point temperature of the glass sealing strip is tested. The movable part of the variable position positioning member is fixedly connected with other temperature sensors, and the temperature sensor is constrained to move along the periphery of the glass sealing strip. , by controlling the position of the test point of the temperature sensor, the temperature test of different points of the glass sealing strip can be realized. The invention discloses a method for encapsulating a photoelectric device, which controls the output power of a laser, the moving speed and direction of a laser beam by performing real-time fixed-point temperature collection and real-time non-fixed-point temperature collection on the temperature at a glass sealing strip. The invention can simply and real-timely measure the temperature at different positions of the bonding place of the glass frit, and has simple structure and high efficiency.

Description

technical field [0001] The invention relates to a photoelectric device packaging technology, in particular to a temperature acquisition system and the use of the temperature acquisition system to collect laser bonding temperature to carry out a photoelectric device preparation process, which is used in the technical field of photoelectric device packaging. Background technique [0002] Organic light-emitting diode display technology has been valued due to its excellent luminous performance and wide application prospects. OLED has the advantages of high brightness, good color contrast, wide viewing angle, fast refresh rate and low energy consumption. However, the organic light-emitting layer and electrodes in the OLED device are very sensitive to oxygen and moisture in the surrounding environment, and will interact with it to degrade, thus greatly affecting the service life of the OLED device. The organic light-emitting layer and electrodes in the OLED device are separated f...
