Description

Technical Field

[0001] The utility model relates to the technical field of radiator fin production and processing, in particular to an open fin collection and turning device. Background Art

[0002] Fins are an important part of the cooling system. In order to solve the problem of frosting in the air conditioner drainage, with the development of technology, a new type of fins that replace the original corrugated fins was born, namely open fins. Since the thickness of the open fins is only 0.07mm-0.12mm and the length is 1500mm, it is very difficult to collect. At present, the only way to solve the current problem is to collect them manually during production.

[0003] Chinese patent CN104071560A discloses a fin vertical flipping device for a heat exchanger core integrated unit, including a sheet conveying guide wheel frame, a vertical guide column, a vertical slider, a vertical knife frame, a sheet vertical knife, a cylinder body, a piston rod, a stroke adjustment column and a cylinder frame. A sheet conveying roller group is arranged at equal intervals along the fin conveying direction on the sheet conveying guide wheel frame, a vertical guide column is vertically arranged on the sheet conveying guide wheel frame, and a vertical slider is matched on each vertical guide column, and the vertical slider is fixed on the vertical knife frame. The vertical knife frame is arranged in the sheet conveying guide wheel frame, and a sheet vertical knife is arranged on the upper end surface of the vertical knife frame in parallel with the conveying direction of the fin. The cylinder body is fixed on the bottom plate of the cylinder frame, and the upper end of the cylinder frame is fixed on the sheet conveying guide wheel frame. The upper end of the piston rod is connected to the vertical knife frame, the upper end of the stroke adjustment column is fixed on the vertical knife frame, the lower end of the stroke guide column is sleeved on the bottom plate of the cylinder frame, and the nut is screwed on the lower section of the stroke adjustment column, which can convert the aluminum fin from a horizontal state to a vertical state.

[0004] Chinese patent 104070121A discloses a fin scraping device for a heat exchanger core integrated unit, including a scraper frame, two parallel linear modules, a universal transmission shaft, a scraper servo motor, a movable guide rail seat, a guide rail cross plate, a cylinder, a lifting plate and a scraper plate. The scraper frame is mounted above the fin vertical flipping device, the linear module is driven by a servo motor, the two linear modules are synchronously connected by a universal transmission shaft, the movable guide rail seat is realized by the two linear modules to achieve reciprocating linear movement, and the scraper plate is driven by the cylinder to achieve up and down sliding. Since the scraper plate is mounted above the fin vertical flipping device, it can be lifted and lowered in a straight line in the vertical direction and can be reciprocated in a straight line in the horizontal direction. The scraper plate can be precisely controlled in position in the horizontal direction through a control system, and can be lifted and lowered in the vertical direction according to people's predetermined requirements to achieve counting scraper conveying, and it can accurately count, scrape or store the fins after vertical flipping.

[0005] However, the above technical solution has the following problem: the fins collected by the above-mentioned fin vertical flipping device and the fin scraping device have their openings facing downwards. Since the fins are thin, the structural strength at the openings is low. Moving the fins with the openings facing downwards is prone to cause deformation of the fins, which is not conducive to subsequent transportation and installation. Utility Model Content
