Description

Technical Field

[0001] The invention relates to the technical field of layer frame processing equipment, and in particular to a layer frame welding equipment and a welding method. Background Art

[0002] The shelf structure of the storage rack is composed of a shelf and a side rail, which is made by welding the side rails to the four sides of the shelf. The traditional welding of the side rails and the shelf is to first position and fix the side rails and the shelf through the corresponding positioning equipment, and then weld the positioned and fixed side rails and the shelf by manually holding a welding gun, and it can only weld the side rails to one side of the shelf at a time, and it cannot weld the side rails to the two sides of the shelf at the same time, so that the manual welding of the side rails and the shelf not only has the shortcomings of low welding efficiency, poor welding accuracy and poor welding effect, but also leads to high labor intensity of workers and high labor costs of enterprises, which cannot meet the requirements of large-scale and batch production of enterprises. In response to the above problems, the publication number: CN202322667215.6 discloses a shelf side rail welding machine, including a feeding mechanism, a shelf support plate arranged on one side of the feeding mechanism, and a welding mechanism arranged above the contact between the shelf and the side rail. The overall structural design of the utility model can automatically complete a series of operations such as loading, material distribution and positioning, welding material collection, welding feeding, clamping and positioning before welding, and synchronous welding of the side fences of two adjacent sides of the rack, and the process of welding the side fences of the rack does not require human participation, so that the rack can automatically weld the side fences. It not only has the advantages of high welding efficiency, high welding precision and good welding effect, but also can reduce the labor intensity of workers and reduce the labor cost of enterprises, so as to effectively solve the problem of low welding efficiency, poor welding precision, poor welding effect, high labor intensity of workers and high labor cost of enterprises caused by the traditional method of using manual handheld welding guns to weld the side fences and racks.
