[0002] The storage grids in refrigerators and freezers are generally made of steel wire materials, and are made into a mesh structure by bending, cutting, welding, dipping and other processes. Among them, in the welding process, manual welding is currently mainly used. In the specific operation, the steel wires are first arranged into a mesh structure in the horizontal and vertical directions, and then the connection points of the horizontal and vertical steel wires are welded with a handheld welding gun. During the welding process, the steel wires need to be supported by hand to prevent them from deviating. However, manual operation is inefficient, the process of placing the steel wires is cumbersome, and the accuracy of the placement of the steel wires cannot be guaranteed, which will lead to different mesh sizes on the welded grids and poor product consistency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0015] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
