When the surface of the armrest frame is in an uneven state, the spring 7 is compressed to provide a certain channel for the contraction of the flattening roller 9, so that one side of the skin is stuck to the armrest frame, and then the remaining surfaces of the armrest frame are wrapped with the transportation of the circular conveyor 2, which improves production efficiency while reducing the generation of wrinkles and reducing the possibility of subsequent rework.

[0026] In this embodiment, a third electric push rod 12 is fixedly installed on the top outer surface of the fixed column 11, and the output end of the third electric push rod 12 is fixedly connected to a ring tube 13. The outer surface of the ring tube 13 is fixedly connected to a cold air nozzle 14. Specifically, the air cooler delivers cold air to the ring tube 13, and the cold air is blown out through the cold air nozzle 14 to cool the skin surface.

[0027] In this embodiment, the output end of the ring conveyor 2 is provided with several equidistantly arranged mounting plates, and the top outer surfaces of the several mounting plates are all installed with positioning workpiece molds 16. Specifically, the automobile armrest frame is put on the surface of the positioning workpiece mold 16, and the automobile armrest frame is supported by the positioning workpiece mold 16.

Two springs 7 are respectively sleeved on the outer surfaces of the two movable rods. Specifically, when the flattening roller 9 moves, the movable rod moves on the surface of the connecting plate 6, and the spring 7 is limited by the movable rod to avoid tilting deformation of the spring 7.

[0029] In this embodiment, a support plate is fixedly connected between the outer surfaces of the bottoms of the two movable rods, a hot air pipe 17 is fixedly connected to the outer surface of the support plate, and a plurality of hot air nozzles 18 are fixedly connected to the outer surface of the hot air pipe 17. Specifically, the hot air blower transports hot air into the hot air pipe 17 and sprays the hot air out through the hot air nozzles 18 to heat the surface, and the hot melt adhesive on the inside of the surface is heated and melted and pasted to the armrest frame.

[0030] In this embodiment, the outer surface of the hot air pipe 17 is fixedly connected to a first telescopic hose, and the other end of the first telescopic hose is fixedly connected to an external hot air blower. Specifically, the hot air generated by the hot air blower is transported to the hot air pipe 17 through the first telescopic hose.

[0031] In this embodiment, a second telescopic hose 15 is fixedly connected to the outer surface of the annular tube 13 , and the other end of the second telescopic hose 15 is fixedly connected to an external air cooler. Specifically, the cold air generated by the air cooler is transported into the annular tube 13 through the second telescopic hose 15 .

[0032] In this embodiment, four groups of mounting columns 1 are respectively arranged on the left and right sides and the front side of the circular conveyor 2, and each group of two mounting columns 1 are respectively arranged on both sides of the conveying track of the circular conveyor 2, and the two groups of flattening rollers 9 and fixing needles 10 on the left and right sides are arranged in an array, and the two groups of flattening rollers 9 and fixing needles 10 on the front and rear sides are staggered. Specifically, when the automobile armrest frame passes through a group of mounting columns 1 on the left, the left surface of the armrest frame is edged; when the automobile armrest frame passes through a group of mounting columns 1 on the right, the right surface of the armrest frame is edged; when the automobile armrest frame passes through the two groups of mounting columns 1 on the front side, the front and rear sides of the armrest frame are edged respectively.

[0033] It is worth noting that the ring conveyor 2 is a known mature technology for ring conveying of articles in the prior art, and the positioning workpiece mold 16 is a known mature technology for supporting the automobile armrest frame in the prior art. Therefore, the ring conveyor 2 and the positioning workpiece mold 16 are only used in this application and are not improved, so they are not elaborated in detail.

[0034] Working principle: When the present invention is in use, multiple automobile armrest frames are respectively put on multiple positioning workpiece molds 16, and the skin is put on the automobile armrest frame, and the circular conveyor 2 is used to transport the automobile armrest frame. When the first automobile armrest frame is transported to the leftmost side, the first electric push rod 3 at the fixing needle 10 of the left group works, and the first electric push rod 3 drives the fixing needle 10 to move upward, so that the fixing needle 10 corresponds to the skin positioning hole on the surface of the automobile armrest frame. The second electric push rod 5 works to drive the fixing needle 10 to insert into the skin positioning hole to position the skin, and then the first electric push rod 3 at the flattening roller 9 works to drive the flattening roller 9 to correspond to the top of the skin. The second electric push rod 5 is turned on to make the flattening roller 9 contact with the surface of the skin, and the hot air is transported to the hot air pipe 17 through the hot air blower, and the hot air is ejected through the hot air nozzle 18 to heat the skin. The hot melt adhesive on the inside of the skin is heated and melted and pasted to the armrest frame. The first electric push rod 3 is slowly retracted to drive the flattening roller 9 to paste the skin to the armrest frame. When the surface of the armrest frame is in an uneven state, the spring 7 is compressed to provide a certain channel for the contraction of the flattening roller 9, so that one side of the skin is pasted on the armrest frame, and then the remaining surfaces of the armrest frame are wrapped as the circular conveyor 2 conveys. While improving production efficiency, it reduces the generation of wrinkles and reduces the possibility of subsequent rework.

[0035] When the armrest frame completes edging and passes through the third electric push rod 12, the third electric push rod 12 extends, causing the annular tube 13 to rise, providing a channel for the movement of the armrest frame, and when other armrest frames are edging, the third electric push rod 12 is retracted, and the air cooler delivers cold air to the annular tube 13, and blows the cold air out through the cold air nozzle 14 to cool the surface of the skin, and then the cooled armrest frame is removed, and the armrest frame that has not been edged is put on, and a cyclic edging work is carried out, which further improves production efficiency.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
