Edge Trimming Method for Solar Cell Modules

Abstract

The invention aims at overcoming the shortcoming that tempered glass forming a battery module is easily broken when the battery module is subjected to edge trimming by means of a battery module edge trimming method in the prior art and providing a solar cell module edge chamfering method capable of reducing breakage rate of the tempered glass forming the battery module. An edge chamfering device is adopted to conduct edge chamfering on the battery module and is provided with an edge chamfering knife. By means of the solar cell module edge chamfering method and due to the fact that slant cutting feed is conducted on a workpiece at the position away from the end of the battery module, corners of the tempered glass are staggered during cutting feed, and the side portion of the tempered glass serves as a cutting feed position, so that the easily-broken positions of the tempered glass are avoided, damage possibility of the tempered glass is reduced, and the breakage rate of the battery module is reduced. Due to the fact that the feeding direction of the knife and the direction of the side portion of the battery module form an included angle of smaller than 90 degrees during cutting feed and is not easily clamped by the tempered glass and the breakage rate of the battery module is reduced, the technical problem that the tempered glass easily breaks when the battery module is subjected to edge trimming is effectively solved, and the finished product rate of the battery module is improved.

Description

technical field [0001] The invention relates to a method for trimming the edge of a solar battery module. Background technique [0002] In the field of solar cell module production, automated production is the direction of development. During this development process, the requirements for the automation of various solar cell module production equipment are getting higher and higher. For example, for the trimming of solar cell When the process is automated, when the electric trimming tool feeds from the end of each side, the tempered glass that makes up the battery component is easily broken, which reduces the yield of the trimming process and affects the production efficiency of the trimming process. cost of production. In addition, in the process of trimming, tempered glass is easy to break. In order to solve the technical problem of tempered glass breakage, technicians have conducted research on parameters such as the structure of the knife, the depth of the knife, and th...

In addition, in the process of trimming, tempered glass is easy to break. In order to solve the technical problem of tempered glass breakage, technicians have conducted research on parameters such as the structure of the knife, the depth of the knife, and the amount of knife movement, but the problem of glass fiber reinforced plastic is easy to break has never been effectively resolved
