Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the laser scribing machine provided by the present application and the evaluation method of its process capability will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] The process capability of the laser scribing machine can be obtained by intersecting the process windows of all laser beams after the process range of each laser beam is determined to obtain the best process window. Because different laser beams have different optimal focal lengths and powers due to manufacturing and installation errors, and laser beams are precision-processed, the greater the laser beam power and the laser beam focal length, the better.

Abstract

The invention relates to a laser scribing machine and an evaluation method of the process capability of the laser scribing machine. According to the evaluation method for the process capability of thelaser scribing machine, process execution data of the laser scribing machine can be found and determined in process matching data according to process requirements, and process parameters of the laser scribing machine can be quickly and accurately controlled. A controller of the laser scribing machine obtains the process requirements. The pre-stored process matching data is obtained from the laser scribing machine. Parameters corresponding to the process requirements are selected from the process matching data, and the laser scribing machine is made to carry out laser irradiation, so that anaccurate laser scribing process is achieved. The evaluation method of the process capability of the laser scribing machine is simple and easy to operate, various factors can be comprehensively considered to pre-store the process matching data, and the process parameters of the laser scribing machine can be quickly and accurately controlled.

Description

technical field [0001] The present application relates to the field of process equipment, in particular to a laser scribing machine and an evaluation method for its process capability. Background technique [0002] Photovoltaic technology is a technology that can directly convert solar energy into electrical energy. The development of photovoltaic technology is also affected and promoted by various factors in society. At present, a laser scribing machine is often used in the preparation of solar cells to scribe the substrate or each film layer. The monitoring of the laser beam power of the laser marking machine needs to be measured by an offline detection module. The detection method for the focal length of the laser beam of the laser marking machine is usually to judge the influence of changing the focal length of the laser beam on the graphics under the condition of fixed energy. [0003] In the traditional energy detection method, when there is a problem with the energy...
