Description

Technical Field

[0002] As a core component of an air conditioning system, a heat exchanger typically consists of a U-shaped copper tube and fins mounted on it.

Finally, the U-shaped copper tube is inserted into the fin bank, complete with the end plates.

[0003] In the actual production process, a row of fins installed on the auxiliary steel needles are relatively loose before being inserted into the U-shaped copper tube, which affects the subsequent assembly of the end plate and the U-shaped copper tube and increases the assembly time.

[0082] The fin group transfer device 5 can press the end plate and the fin group tightly and transfer the fin group to the downstream equipment.

[0083] This embodiment provides an intelligent transfer and stacking device for heat exchanger fins in the refrigeration field. The fin pressing device 2 is used to press the fins on the stacked multiple fin groups to facilitate the installation of the end plates. The stacked multiple fin groups are destackered by the destacker 3, so that the end plate installation device 4 can pass the end plates on the auxiliary steel needles at both ends of the destackered fin group. The end plates and the fin group are pressed by the fin group transfer device 5, and the pressed fin group is transferred to the downstream equipment to facilitate the downstream equipment to assemble the fin group and the U-shaped copper tube.

The travel direction of the transverse mechanism is parallel to the conveying direction, and the travel direction of the lifting mechanism is vertical to the conveying direction.

[0086] The flip unit 9 includes a flip mechanism and a lifting mechanism. The flip mechanism is arranged on the lifting mechanism. The travel direction of the lifting mechanism is vertically perpendicular to the conveying direction. The flip mechanism can rotate the fin group 180 degrees.

[0087] The conveyor frame 1 is provided with a front end transfer mechanism 6 and a rear end transfer mechanism 7 along the conveying direction;

[0088] The front end transfer mechanism 6 can transfer the stacked multiple fin groups from the working area of the fin pressing device 2 to the working area of the destacking unit 8;

[0089] The rear end transfer mechanism 7 can sequentially transfer the fin group from the working area of the destacking unit 8 to the working areas of the flip unit 9, the end plate installation device 4 and the fin group transfer device 5;

[0090] The fin groups made by the upstream equipment are stacked in groups of two or three, and the fin groups in each stack are stacked alternately forward and backward. The fin groups need to be flipped during the destacking process so that the destacking fin groups are all placed upright to ensure the normal installation of the subsequent end plates and U-shaped copper tubes. Manual flipping is inconvenient. By setting up a flip unit 9, the fin group can be rotated 180 degrees, thereby effectively reducing the labor intensity of the workers.

At this time, the fin group enters the working area of the destacking unit 8 ( Figure 8 The left stroke limit position of the first linear module 801).

[0096] In a specific embodiment, Figure 7 As shown, the conveyor frame 1 is provided with two oppositely arranged destacking devices 3, as shown in FIG. Figure 7 and Figure 8 As shown, the destacking device 3 further includes a base plate 301, and the base plate 301 is fixed on the conveying frame 1;
