a conveying platform for conveying a refrigerator housing;

a foaming material spray gun head;

a vacuum insulation panel placer for taking and placing a vacuum insulation panel; and

a press-fitter for adhering the vacuum insulation panel on the refrigerator housing;

wherein the foaming material spray gun head, the vacuum insulation panel placer and the press-fitter are sequentially arranged in a moving direction of the conveying platform, the foaming material spray gun head is fixedly disposed beside the conveying platform, and the press-fitter has rollers for rolling the vacuum insulation panel;

wherein the press-fitter has a pair of first side walls arranged oppositely and extending in a widthwise direction of the conveying platform, a pair of second side walls extending in a lengthwise direction of the conveying platform, and a top wall connecting the first side walls and the second side walls, and the rollers are pivotally connected between the second side walls, the vacuum insulation panel application device further comprises a detection platform for detecting performance of the vacuum insulation panel before being placed to a foaming material spraying position of the refrigerator housing, after the vacuum insulation panel is detected as being qualified, the vacuum insulation panel is placed on the foaming material spraying position for spraying, when the vacuum insulation panel fails to pass detection of the detection platform, a next vacuum insulation panel is then picked up for detection; the foaming material spray gun head gradually sprays foaming material toward an application region of the refrigerator housing as the conveying platform moves the refrigerator housing; and a position of the refrigerator housing is monitored in real time during spraying by a position sensor on the conveying platform, and a control module controls the foaming material spray gun head to spray and finish spraying according to the position of the refrigerator housing.
