Description

Transverse inserted fin assembling equipment and process Technical Field The invention relates to the technical field of micro-channel heat exchanger core processing, in particular to a transverse insertion fin assembling device and method. Background The metal fin in the flat tube microchannel heat exchanger is usually formed by processing an uncoiled metal thin strip through procedures such as stamping, slitting, cutting and the like. Through stamping processing, the fin is provided with a notch part for installing the flat tube, a window opening part for guiding hot gas, foolproof bulges distributed along the edge of the fin and the like. Through interline slitting, the metal thin strip is divided into a plurality of metal strips with set widths. And finally, the metal strip is cut along the length direction to form the fin to be assembled with the set length. As shown in fig. 9, in the conventional technology, the fins are aligned during punching, that is, all the fins are arranged in a manner that the front face (convex face) faces upwards, the notch faces towards the same side and is aligned, so that after slitting and cutting, all the fins can be synchronously reset and pre-pressed, for example, all the fins are turned to a set angle by adopting a synchronous turning mechanism, and at the moment, the fins face uniformly and are consistent with the pre-pressed direction, so that the implementation of the subsequent assembly process is facilitated. However, the fins in the arrangement mode are easy to generate stress at comb teeth of the fins during punching, so that the fins are deformed in a buckling manner during transferring, the fins are not easy to accurately position during conveying, and sheet bodies are easy to damage. In order to solve this problem, as shown in fig. 8, there is a method of arranging fins symmetrically in the prior art, so that the stress generated by the fins during punching can be reduced to a certain extent, and the above-mentioned phenomena such as buckling deformation can be avoided. However, since the fins distributed symmetrically cannot be synchronously arranged before press fitting, the fins need to be subjected to layering treatment after cutting and outputting, namely, each fin pair in symmetrical arrangement, wherein one row needs to be output to an upper layer and the other row needs to be output to a lower layer, and after the two rows are separated, the fins in each layer are uniformly arranged, transferred, pre-pressed and finally laminated. Because the upper layer fins and the lower layer fins are different in orientation after being placed, in the prior art, a method of arranging two sets of different lamination structures is generally adopted to carry out lamination treatment on the fins on different layers, and in order to enable the two nesting press mechanisms to synchronously work, parallel transfer components, prepressing devices and the like are also required to carry out pretreatment on the fins. In summary, it can be seen that the existing fin processing output in a symmetrical arrangement mode needs two different structures such as arrangement, pre-pressing, laminating and the like after layering, and the press-fitting forming of the fin and the flat tube can be completed, so that the equipment cost is high and the intensive and miniaturized equipment is not facilitated. Disclosure of Invention The invention aims to solve the technical problems of overcoming the defects of the prior art and providing transverse inserting fin assembling equipment and process, by adopting the equipment and the process, the press-fitting feeding structures of different fin rows facing the layered fins can be simplified, the fin assembling efficiency is ensured, the equipment cost is further reduced, and the space occupied by the equipment is reduced. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: A transverse inserting fin assembling device is characterized by comprising a layered conveying device, a vertical overturning device and a press-fitting feeding device, wherein the layered conveying device is used for inputting paired fins and separating the paired fins into an upper fin row and a lower fin row which are transported in parallel according to an upper layer and a lower layer, the vertical overturning device is used for receiving the upper fin row or the lower fin row and overturning the upper fin row or the lower fin row to a standing posture, the front faces of the upper fin row and the lower fin row are opposite after standing, and the press-fitting feeding device comprises a frame body, an upper pushing part and a lower pushing part, wherein the upper fin row and the lower fin row are pushed to be intensively output from the vertical overturning device in an initial state, the lower pushing part is used for pushing the upper fin row and the lower fin row after standing to be intensively output from the ver
