Abstract
Description
Technical Field
[0001] The present application relates to a heat pump evaporator preparation technology, and relates to the assembly of copper tubes and fins, and in particular to a heat pump evaporator fin arrangement device. Background Art
[0002] The heat exchange module of the heat pump evaporator needs to be formed by copper tubes and fins. Generally, the copper tubes and fins are processed separately. The fins are selected into plate types / sheet types of predetermined sizes, and then multiple through holes are formed on them according to the positions where the copper tubes are inserted as needed. During assembly, the copper tubes need to be inserted into the fins of the array. If the spacing between the fins is not well controlled, it will have a certain impact on the heat exchange effect of the formed module. Therefore, it is necessary to arrange the fins evenly and stably during assembly to facilitate the insertion of the copper tubes into the fin array. Utility Model Content

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0017] The present application embodiment provides a heat pump evaporator fin arrangement device, such as Figure 1-Figure 4 As shown, it is arranged on a workbench 1 and is used to arrange the fins 11 to be assembled in an array. The device of this example includes an inverted L-shaped plate 2, a push plate 5, etc.
[0018] like Figure 1-Figure 3 As shown, the inverted L-shaped plate 2 is arranged above one side of the workbench 1, and its inner top wall and inner side wall are arrayed with slots 20 in the length direction of the workbench 1, and the slots 20 are in an inverted L shape for matching with the fins 11. Specifically, the length of the inverted L-shaped plate 2 and the width and interval of the slots 20 are designed according to requirements. The inverted L-shaped plate 2 is arranged at the moving end of a vertical linear mechanism 3 through a mounting plate, so that it can move vertically to adjust and adapt to fins 11 of different widths.
[0019] The vertical linear mechanism 3 is arranged to move along the width direction of the workbench 1, and can be specifically arranged at the moving end of a horizontal linear mechanism 4, so that it can realize horizontal movement consistent with the width direction of the workbench 1 to adjust and adapt to fins 11 of different lengths and sizes. At the same time, according to different needs, the inverted L-shaped plate 2 of different lengths and widths and intervals of the slot 20 can be replaced by the mounting plate to adapt to more shapes and sizes of the fins 11. Optionally, the vertical linear mechanism 3 and the horizontal linear mechanism 4 can adopt linear travel modules / mechanisms such as linear electric rods, ball screws, and motor screws.
[0020] like Figure 1 , Figure 2 , Figure 4 As shown, the push plate 5 is arranged on the other side of the workbench 1 and arranged in an array along the length direction of the workbench 1. The number of push plates 5 is consistent with the number of slots 20, and the positions correspond one to one. The push plates 5 are arranged to move along the width direction of the workbench 1. Specifically, they are all penetrated on a bracket 51, and the section of the push plate 5 penetrating the bracket 51 is rectangular in cross section. The bracket 51 has a square through hole matching the rectangle, so that when the push plate 5 is moved, it has a certain stability and alignment. The front end surface of the push plate 5 is concave to form a limiting groove 50 for matching with the fin 11.
[0021] The outer side of the bracket 51 is convexly formed with a rod-piercing platform 54, on which a limiting rod 53 is penetrated, and a limiting hole 52 is set through the rear of the push plate 5. The axis of the limiting rod 53 is parallel to the length direction of the workbench 1. The limiting rod 53 is arranged to move along its own axis direction.
[0022] When in use, first adjust the position of the inverted L-shaped plate 2 to an appropriate position to match the size of the fin 11 that currently needs to be assembled. The adjustment of the initial position can be combined with the loading. First, for the first fin 11 to be loaded, stand it upright and place it on the workbench 1 for support, and then first fit one end of it into the limiting groove 50 of the push plate 5, and then push the push plate 5 forward so that the position of the limiting hole 52 matches the axis of the limiting rod 53, and move the limiting rod 53 to the limiting hole passing through the push plate 5, and temporarily fix the position of the push plate 54; then, adjust the position of the inverted L-shaped plate 2 through the vertical linear mechanism 3 and the horizontal linear mechanism 4 so that the slot 20 on it matches the two sides of the fin 11. Then, keep the position of the inverted L-shaped plate 2 unchanged, and continue to load the fins 11 onto the workbench 1. The fins 11 that continue to be loaded are first placed in a manner that cooperates with the card slot 20, and then the push plate 5 is moved to achieve the cooperation between the fins 11 and the limit slot 50. Each time a fin is cooperated, the limit rod 53 is moved a certain distance to fix the position of the push plate 5 after movement.
[0023] Preferably, most or all of one side of the slot 20 can be set through, that is, through the transverse portion of the inverted L-shaped plate 2, so that after the position of the inverted L-shaped plate 2 is initialized, the subsequent loading of the fin 11 can be quickly inserted through the through position. Of course, as an optional method, the size of the transverse portion of the inverted L-shaped plate 2 can also be shortened to make the distance the transverse portion extends shorter, which can also facilitate the loading of the fin 11. The travel of the push plate 5 can also be set according to demand, that is, the difference in position before the movement and when it moves to be limited by the limit rod 53, to adapt the loading of the fin 11. Of course, whether it is adjusting the size of the inverted L-shaped plate 2, setting the form of the slot 20, or adjusting the movable travel range of the push plate 5, it only needs to meet that after the position of the inverted L-shaped plate 2 is initialized, the fin 11 can be placed on the workbench 1 and fit into the limit groove 50 of the push plate 5.
[0024] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
