Flat tube conveying mechanism in assembly process of heat exchanger core

Abstract

The invention discloses a flat tube conveying mechanism in the assembly process of a micro-channel heat exchanger core. The flat tube conveying mechanism comprises a rack and is characterized in that a flat tube placing base is installed on the rack through a lifting device, flat tube transferring mechanisms are arranged above the flat tube placing base, vacuum suction cups are arranged on the flat tube transferring mechanisms, flat tube conveying belts matched with the flat tube transferring mechanisms are arranged behind the flat tube transferring mechanisms, and flat tube assembly rotating discs matched with the flat tube conveying belts are arranged at the rears of the flat tube conveying belts. The flat tube conveying mechanism has the advantages that the structure is simple and reliable, efficiency is high, the mechanization and automation degree is high, flat tube deformation and contact between flat tubes and other hard substances (such as steel) are avoided to the maximum degree, damage to the flat tubes by mutual friction between the flat tubes is avoided to the maximum degree, and the damage is definitely not allowed for the high-quality micro-channel heat exchanger core.

Description

technical field [0001] The invention relates to a material conveying mechanism, in particular to a flat tube conveying mechanism in the assembly process of a heat exchanger core. Background technique [0002] In the prior art, heat exchangers are mostly used in some special industrial equipment. During production, wavy cooling fins are placed between flat tubes for combined installation. Since the flat tubes are very thin and made of aluminum alloy, It is very soft and the surface is easy to scratch, so the flat tube heat exchanger was installed manually in the past, but the manual installation has the disadvantage of low efficiency. Now there are some equipment that use mechanical devices for automatic assembly, mainly using mechanical claws to grab the flat tubes of the heat exchanger core and assemble the heat exchanger core, but the existing equipment is to stack the flat tubes On the installation frame, use a mechanical device to push out a flat tube stacked on the bot...

[0002] In the prior art, heat exchangers are mostly used in some special industrial equipment. During production, wavy cooling fins are placed between flat tubes for combined installation. Since the flat tubes are very thin and made of aluminum alloy, It is very soft and the surface is easy to scratch, so the flat tube heat exchanger was installed manually in the past, but the manual installation has the disadvantage of low efficiency

Now there are some equipment that use mechanical devices for automatic assembly, mainly using mechanical claws to grab the flat tubes of the heat exchanger core and assemble the heat exchanger core, but the existing equipment is to stack the flat tubes On the installation frame, use a mechanical device to push out a flat tube stacked on the bottom layer. Since the flat tubes of the heat exchanger are thin, they are prone to deformation due to the drop of the flat tubes of the heat exchanger and rub against each other when they are pushed out. It is easy to leave scratches on the surface of the tube wall. When the heat exchanger is running, the high-pressure medium inside the flat tube of the heat exchanger will generate stress at the scratches, which will damage the heat exchanger. Therefore, it is necessary to design a new heat exchanger. Flat tube conveying mechanism during core body assembly
