Description

Technical Field

[0001] The invention relates to a refrigerator parts production line, in particular to a refrigerator bottom foot lower front plate assembly production line. Background Art

[0002] The front plate at the bottom of the refrigerator is a sheet metal part, which is one of the components of the refrigerator shell. The front plate at the bottom of the refrigerator generally needs to go through the following processes during production and processing: metal plate cutting, stamping, sponge patch pasting, roller installation and other parts.

[0003] In the traditional production process, each process is carried out separately. Therefore, when the workpiece is transferred from one process to another, it is often necessary for the operator to carry it. Take the process of sticking sponge patches as an example. Due to different products, sometimes several sponge patches of different sizes and shapes need to be stuck on a workpiece. Therefore, just one sponge patch sticking process often needs to be divided into multiple processes. At the same time, the sponge patch rolls used for sticking sponge patches are large in size. For the convenience of operation, operators often need to cut them according to their own operating habits, and then put the cut sponge patches aside. Each time the sticking process needs to take the sponge patches one by one, and they need to be cut again after use, so the overall efficiency needs to be improved.

[0004] When assembling parts, different types of products often require the assembly of multiple parts. The traditional method is to put the parts in a frame, put the frame on the operating table, and then the operator grabs them from the frame for installation, and the overall efficiency needs to be improved.
