The invention provides an automatic assembly line for packing glass and a packing method and relates to the technical field of glass packing. The automatic assembly line and the packing method solve the technical problem that manual glass packing efficiency is low in the prior art is solved. A device comprises a conveying platform, a plate feeding device, a first packing device and a second packing device. The glass to be packed is put on a glass support plate, the glass support plate is put on the conveying platform, and the glass support plate and the glass to be packed can sequentially passthe plate feeding device, the first packing device and the second packing device under the drive of the conveying platform. The plate feeding device can put wooden plates on the side faces and the top faces of the glass to be packed. The first packing device and the second packing device can wind packing belts around the glass support plate outside the glass to be packed in the horizontal direction and the vertical direction and the wooden plates and fix the glass support plate and the wooden plates to the glass to be packed through the packing belts. By the adoption of the automatic assemblyline for packing the glass, the glass can be packed automatically, the time and labor are saved, and large-scale packing of the glass is achieved easily.
