[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1-4 As shown, the utility model provides an automatic conveying device for assembling refrigerator door components, which includes a bottom plate 11, a limit plate 12, a slide rail 20, a slide seat 30, and a bearing plate 40.

[0027] The limit plates 12 are arranged at both ends of the base plate 11, and the limit plates 12 are arranged vertically to the slide rails 20. The height dimension of the limit plates 12 is greater than the height dimension of the slide rails 20. The limit plates 12 are used to realize the movement limit position of the slide seat 30 along the slide rails 20, wherein the slide rails 20 are arranged on the base plate 11, and the two slide rails are arranged at intervals and extend along the length direction of the base plate 11.

[0028] A sliding groove 31 corresponding to the slide rail 20 is provided on the bottom of the slide seat 30 . The sliding groove 31 is connected with the slide rail 20 and the slide rail 20 is at least partially accommodated in the sliding groove 31 . The slide rail 20 guides the movement of the slide seat 30 .

[0029] The slide 30 is driven by a driving component to move along the slide rail 20 . For example, the driving component is a cylinder, a hydraulic cylinder or a gear rack transmission combination. The driving component can drive the slide 30 to move linearly along the slide rail 20 .

[0030] The bearing plate 40 is fixedly disposed on the slide seat 30 . The bearing plate 40 is used to bear the refrigerator door body component. The bearing plate 40 is provided with a mounting hole 41 . The refrigerator door body component is connected to the bearing plate 40 through the mounting hole 41 .

[0031] The sliding groove 31 includes a bottom surface 311 and a first side wall 312 arranged on both sides of the bottom surface 311, and the sliding rail 20 includes a top surface 21 and a second side wall 22 arranged on both sides of the top surface 21, and the spacing dimension between the first side walls 312 arranged on both sides of the bottom surface 311 is greater than the spacing dimension between the second side walls 22 arranged on both sides of the top surface 21.

[0032] When the sliding groove 31 is connected with the slide rail 20, the bottom surface 311 is opposite to the top surface 21 and there is a moving gap in the vertical direction. Specifically, the slide seat 30, as a moving component, usually needs to support the refrigerator door body component while realizing mobile transmission. In order to prevent the refrigerator door body from causing greater pressure or contact on the slide rail 20 when the slide seat 30 moves, thereby causing greater friction between the slide seat 30 and the slide rail 20, which also affects the stability of the movement, a moving gap is reserved in the vertical direction between the bottom surface 311 of the slide seat 30 and the top surface 21 of the slide rail 20.

[0033] An oil guide groove 211 is provided on the top surface 21 , and the oil guide groove 211 is recessed on the top surface 21 . A plurality of oil guide grooves 211 are spaced apart along the length direction of the slide rail 20 . The oil guide grooves 211 are recessed on the top surface 21 and spaced apart along the length direction, thereby forming protrusions between adjacent oil guide grooves 211 .

[0034] The two ends of the oil guide groove 211 extend to the surface of the second side wall 22 respectively. The extending direction of the oil guide groove 211 is not parallel to the length direction of the slide rail 20. Figure 4 L1, and the length direction of the slide rail 20 Figure 4 In L2, the angle between the extension direction of the oil guide groove 211 and the length direction of the slide rail 20 is in the range of 10°-160°. The oil guide groove 211 arranged obliquely along the length direction of the slide rail 20 can make the two ends of the multiple oil guide grooves 211 arranged at intervals along the length direction extend to the surface of the second side wall 22, and then the lubricating grease stored or contained in the oil guide groove 211 flows from the end of the oil guide groove 211 to the surface of the second side wall 22.

[0035] Lubricating grease can be applied on the top surface 21. With the relative movement between the slide rail 20 and the slide seat 30, the lubricating grease can be transported from the oil guide groove 211 to the gap between the first side wall 312 and the second side wall 22, thereby achieving effective lubrication between the slide rail 20 and the slide seat 30. The oil guide groove 211 also has a certain oil storage capacity and the movement of the slide seat 30 can drive the movement of the lubricating grease in the oil guide groove 211, thereby achieving effective lubrication, and also reducing the workload of the staff who need to frequently apply the lubricating grease to the connection between the slide rail 20 and the slide seat 30.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
