Description

Heat dissipation fin manufacturing system The present invention relates to a heat dissipation fin manufacturing system, and more specifically, to a heat dissipation fin manufacturing system in which, during a process of continuously manufacturing heat dissipation fins, an alignment and transfer device that aligns and transfers the heat dissipation fins is configured to measure the travel length of the heat dissipation fins simultaneously with transferring them, thereby enabling the production of products of uniform quality by moving and cutting them to an accurate length. Furthermore, the system is configured so that even when the travel speed of the heat dissipation fins being manufactured is increased toward high productivity, the rotating shaft and bearings responsible for the movement of the heat dissipation fins are not subjected to excessive strain, thereby enabling high productivity and high durability. Heat dissipation fins are generally used as heat dissipation components in fields requiring cooling, such as automobiles or heat exchangers. As disclosed in Korean Registered Patent No. 10-1374979, “Method for Manufacturing a Radiator,” they are typically composed of a plurality of unit fins (41a) and air passage holes (41b). In order to increase the heat dissipation effect, many fin folds, that is, many unit fins (41a), are required. The above unit fins (41a) and air passage holes (41b) are created by making unit cuts at regular intervals on a flat plate, forming fin folds by folding according to the intervals of the unit cuts, and then cutting off a certain amount. In order to continuously create many fin folds, the heat dissipation fin material must be transported at a fast speed and at the same time transported to a cutting device in a certain amount to manufacture a uniform and highly reliable high-quality product. In particular, in order to move the heat dissipation fin material quickly, the heat generation problem of the components responsible for the movement must also be solved, but this has not been possible in the past.

FIG. 2a is a perspective view of an alignment transfer device, which is a component of a heat dissipation fin manufacturing system according to an embodiment of the present invention, and FIG. 2b is a view of FIG. 2a from the opposite side. Figure 3 is a cross-sectional view of the alignment transfer device of Figure 2a viewed in the xy plane. Figure 4 is a view of the alignment transfer device of Figure 2a seen in the yz plane.

The terms used in this invention have been selected to be as widely used as possible; however, in specific cases, terms have been arbitrarily selected by the applicant. In such cases, the meaning should be understood by considering the meaning described or used in the detailed description of the invention, rather than merely the name of the term. Hereinafter, the technical configuration of the present invention will be described in detail with reference to preferred embodiments illustrated in the attached drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Throughout the specification, the same reference numerals indicate the same components.

Specifically, the feeding device (100) is a device that supplies a pin raw material (10a) as in step A, and the pin creasing device (200) is a device that processes the pin raw material (10a) into a first pin processed material (10b) by making a cut (11) in the longitudinal direction with a forming blade (201) as in step B while simultaneously forming a pin creasing. Here, the pin creasing forming device (200) repeatedly rotates the forming blade (201) in place, and on the opposite side, an auxiliary forming device (250) is provided to support the pin original member (10a) during the rotation of the forming blade (201). The above auxiliary forming device (250) forms a plurality of forming grooves (not shown in the drawing) along the longitudinal direction into which the forming blade (201) can be inserted while rotating, and a portion of the pin original member (10a) is compressed together with the pin forming device (200) on the opposite side of the pin forming device (200) to process the pin wrinkles, and the remaining portion guides the transport of the first pin p
