Abstract

A vacuum insulation panel application device and method are provided. The device comprises a conveying platform for conveying a refrigerator housing, a foaming material spray gun head, a vacuum insulation panel placer and a press-fitter for pasting a vacuum insulation panel onto the refrigerator housing, wherein the foaming material spray gun head, the vacuum insulation panel placer and the press-fitter are sequentially arranged in the moving direction of the conveying platform; the spray gun head is fixedly arranged beside the conveying platform; and the press-fitter is provided with rollers for rolling the vacuum insulation panel.

First claim

What is claimed is:

1. A vacuum insulation panel application device, comprising:
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.

2. The vacuum insulation panel application device according to claim 1 , wherein the conveying platform has a fixed frame and a conveying mechanism disposed on the fixed frame, and the position sensor disposed on the fixed frame and configured to sense the position of the refrigerator housing in real time.

3. The vacuum insulation panel application device according to claim 1 , wherein the press-fitter further has a heating element disposed on an inner wall of the top wall.

4. The vacuum insulation panel application device according to claim 1 , wherein a distance between the pair of first side walls is 1-2 times of a length of the refrigerator housing.

5. A method for applying a vacuum insulation panel, wherein the method comprises the following steps:
placing a refrigerator housing on a conveying platform;
spraying foaming material toward an application region of the refrigerator housing as the conveying platform moves the refrigerator housing along the conveying platform to a foaming material spraying station;
conveying the refrigerator housing with the foaming material to a vacuum insulation panel placing station, a vacuum insulation panel placer picking up the vacuum insulation panel and placing the vacuum insulation panel on the application region of the refrigerator housing;
conveying the refrigerator housing provided with the vacuum insulation panel to a pressing station, a press-fitter gradually rolling the vacuum insulation panel as the conveying platform conveys the refrigerator housing, so that the vacuum insulation panel is applied to the refrigerator housing;
wherein before picking up and placing the vacuum insulation panel on the application region of the refrigerator housing, the vacuum insulation panel placer first places the vacuum insulation panel on a detection platform for detection, and then places the vacuum insulation panel on a foaming material spraying position of the refrigerator housing after the vacuum insulation panel is detected as being qualified, or, the vacuum insulation panel placer performs discarding processing when the vacuum insulation panel fails to pass the detection of the detection platform, and then picks up a next vacuum insulation panel for detection.

6. The method for applying a vacuum insulation panel according to claim 5 , wherein a time range for the refrigerator housing in the press-fitter is 5-10 s.

7. The method for applying a vacuum insulation panel according to claim 5 , wherein when the refrigerator housing enters the press-fitter, a heating element in the press-fitter starts to operate and control a temperature within a range of 35-50° C.
