Embodiment Construction

[0027] The present invention proposes a laser packaging method, refer to Figure 1 to Figure 7 , the method includes the following steps:

[0028] Step S20, generating a point laser beam.

[0029] Specifically, a point-shaped laser beam is a laser beam whose irradiation area is a small spot or a spot.

[0030] Step S40, shaping the point-shaped laser beam into a linear laser beam.

[0031] Specifically, the line-shaped laser beam is a laser beam whose irradiation area is a straight line, and can be obtained by passing the point-shaped laser beam through a lens group or using a grating diffraction method.

[0032] In step S60, a mask is set on the packaging material, a light-transmitting area matching the shape of the packaging material is opened on the mask, and the light-transmitting area and the packaging material are aligned.

[0033] Specifically, the encapsulation material is provided on the glass substrate. The mask plate is provided with a light-transmitting area, t...

Abstract

A laser packaging method includes the steps of generating dotted laser beams, shaping the dotted laser beams into linear laser beams, arranging a mask plate on a packaging material, forming a light transmitting zone of which the shape is matched with the shape of the packaging material on the mask plate, aligning the mask plate to the light transmitting zone and the packaging material, and utilizing the linear laser beams to scan the mask plate. By the adoption of the laser packaging method, after the mask plate and sealing patterns are aligned, the linear laser beams scan and irradiate the mask plate, irradiation and hot melting of the whole sealing patterns can be achieved, and the packaging efficiency is improved. After the mask plate and sealing patterns are aligned, laser can accurately irradiate a packaging zone, and the requirement for aligning accuracy of the laser beams is reduced.

Description

technical field [0001] The present invention relates to laser processing technology, in particular to a laser packaging method and equipment. Background technique [0002] The laser sealing method used in the traditional industry is the glass frit scanning method. This method is to encapsulate the upper and lower substrates together through the sealing material, and the laser beam is irradiated on the sealing material and moves point by point along the outline of the sealing pattern to complete the packaging. However, the scanning time of this method is determined according to the size and specific outline of the frit pattern, the packaging efficiency is low, and the precision of laser alignment is high, which is particularly problematic in large-sized packaging. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a laser packaging method for the problem of low packaging efficiency. [0004] A laser packaging method, comprising: generating a point-...
