Description

Technical Field

[0001] The invention relates to the technical field of automobile armrest cover plate covering equipment, in particular to an automobile armrest frame covering skin device. Background Art

[0002] In existing car interiors, a center console armrest box is usually set in the center of the car. It was originally used to provide elbow support for passengers, and later developed into a storage box in the car. In order to obtain a more comfortable experience, the surface of the armrest cover is usually covered with a layer of soft material, generally leather or artificial leather. The current covering method is to cut the skin, apply glue on the edge, and then put it on the armrest cover frame, and glue the edge to the inner side of the bottom of the cover to fix it. For example, the Chinese utility model patent with authorization announcement number CN203959805U discloses a car center console armrest covering device. A car center console armrest covering device includes a base, a plane bearing, a lifting cylinder, a table lifting plate, a nitrogen spring, a rotating block, a rotating table, a rotating shaft, a left-aligned knife die, a right-aligned knife die, a color sensor, a capacitive sensor, an elbow clamp clamping device, and a tire mold, which realizes automated covering. However, the current car armrest cover frame has the following defects when covering the skin:

[0003] Currently, the coating is wrapped in a sleeve-like manner, which only fixes the bottom of the skin. In this way, the rest of the skin is not fixed to the cover frame, which is prone to wrinkling and bulging. The fit is not good enough and the coating stability is not strong enough.
