Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a winged flat tube conveying device. Background Technology

[0002] Finned heat exchange tubes, as highly efficient heat transfer elements, effectively improve heat transfer efficiency by adding fins to the outside of the flow channel to expand the heat transfer area. Flying wing flat tubes are a special type of finned heat exchange tube. They are formed directly on machinable materials such as aluminum alloys through a continuous slicing process, eliminating contact thermal resistance in the heat transfer process and further improving heat transfer efficiency.

[0003] Currently, wing-shaped flat tubes have been widely used in various fields such as air conditioning and refrigeration, petrochemicals, power plants, and waste heat recovery. Depending on the operating conditions, the wing-shaped flat tubes need to be conveyed and processed after the fins have been removed. Because the fins on both sides of the wing-shaped flat tube are thin and dense, they are easily deformed by uneven pressure during conveying, which affects subsequent processing. Therefore, in order to ensure the accurate processing and application of wing-shaped flat tubes, it is necessary to develop a conveying device suitable for wing-shaped flat tubes.

[0023] Example 1

[0024] A flying wing flat tube conveying device, such as Figure 1 As shown, it includes: Guiding components: include an inlet guiding mechanism 11 and an outlet guiding mechanism 12 arranged at intervals along the material conveying direction, respectively configured to guide and constrain the feed end and discharge end of the wing flat tube; Clamping assembly: Located between the inlet guide mechanism 11 and the outlet guide mechanism 12, it clamps or releases the wing flat tube through two oppositely arranged robotic arm mechanisms 21; Drive assembly: includes a linear drive mechanism that is connected to the robot arm mechanism 21 for driving the robot arm mechanism 21 to reciprocate linear motion along the conveying direction, thereby causing the clamped wing flat tube to generate directional displacement.

[0025] It should be noted that, in combination Figure 2 In this embodiment, the flying wing flat tube includes a flow channel and fins 42 shoveled from the two wider sides of the flow channel. The two narrower sides of the flow channel of the flying wing flat tube are provided with raised ribs 41. Optionally, two robotic arm mechanisms 21 are used to clamp or release the ends of the fins 42 on the relatively wider sides of the flying wing flat tube. It should be noted that, because the fins 42 shoveled from both sides of the flying wing flat tube are thin and densely arranged, for simplicity... Figure 2 The structure of a single fin 42 is not shown in the figure.

[0026] The process of using the wing flat tube conveying device in this embodiment includes: the wing flat tube is input through the inlet guide mechanism 11 at the feed end; then, two opposing robotic arms 21 in the clamping assembly clamp the ends of the fins 42 on the relatively wide sides of the wing flat tube. After contacting the ends of the fins 42 of the wing flat tube, the two robotic arms 21 adjust their clamping force to achieve a balanced state, thus achieving a firm and safe clamping; under the action of the drive assembly, the robotic arms 21, along with the clamped wing flat tube, move towards the outlet guide mechanism 12 at the outlet end; after the robotic arms 21 completes the forward stroke, the two opposing robotic arms 21 release the clamping force and release the wing flat tube. The robotic arms 21 then move backward under the drive assembly and return to the inlet guide mechanism 11 end, repeating the clamping, conveying, and releasing operations of the wing flat tube, thereby achieving stable conveying of the wing flat tube.

[0027] Example 2

[0028] Based on the flying wing flat tube conveying device shown in Embodiment 1, this embodiment optimizes the structure of the clamping assembly.

[0029] Optionally, combined Figure 3 The clamping assembly also includes a connecting frame, which includes: a first horizontal plate 221 and a second horizontal plate 222 arranged in parallel, used to fix two robotic arms 21 respectively; a first side plate 223 and a second side plate 224, which are vertically connected to the same end of the first horizontal plate 221 and the second horizontal plate 222 respectively; and a third horizontal plate 225, which connects the other end of the first side plate 223 and the second side plate 224. The connecting frame connects the two robotic arms 21 arranged opposite to each other into one unit, and they move synchronously under the action of the drive assembly. Thus, in actual work, one drive assembly can be used to synchronously drive the two robotic arms 21 in the clamping assembly, which simplifies the device structure and also improves the stability of operation.

[0030] Alternatively, the drive assembly is connected to the robot arm structure via a connecting frame; further still, the drive assembly is connected to the robot arm mechanism 21 via a third horizontal plate 225 in the connecting frame.

The buffer plate 212 is disposed between the linear power structure 211 and the top block 213, and the top block 213 has a working surface 2131 adapted to the side of the wing tube. The linear power structure 211 is used to provide clamping force to the left and right sides of the wing tube, and the buffer plate is an elastic buffer plate used to uniformly transmit the clamping force provided by the linear power structure 211 to the top block 213. Specifically, the clamping force provided by the linear power structure 211 is buffered by the elastic buffer plate 212 and then applied to the side of the wing tube (the end of the fin 42) through the working surface 2131 on the top block 213. When the two opposing robotic arm mechanisms 21 are working, their clamping forces are synchronously applied to the middle wing tube in opposite directions. They can adjust to each other after the working surface 2131 contacts the wing tube until a balanced state is reached, firmly holding the wing tube.

[0034] Optionally, the height of the working surface 2131 on the top block 213 is not greater than the height of the side surface of the wing-shaped flat tube, which helps the robotic arm mechanism 21 to apply pressure more evenly to the end face of the fin 42, firmly clamp the wing-shaped flat tube, and improve the overall stability of the device operation. Optionally, the ratio of the height of the working surface 2131 on the top block 213 to the height of the side surface of the wing-shaped flat tube is (0.4~1):1, preferably (0.8~1):1, and even more preferably 1:1.

[0035] Alternatively, the linear power structure 211 is a cylinder.

[0036] Optionally, the two robotic arms 21 are arranged horizontally or vertically opposite each other, thereby enabling horizontal conveying (with the two wider sides on the top and bottom) or vertical conveying (with the two wider sides on the left and right).

[0041] Alternatively, the linear drive mechanism may further include a guide rail pair 35 arranged along the conveying direction, and the robot arm mechanism 21 is slidably connected to the guide rail pair 35; thereby improving the accuracy of the reciprocating movement of the clamping assembly.

[0042] It should be noted that the connection method of the guide rail pair 35 is not limited in this utility model. It can be connected with the guide frame 34 or with other structures arranged along the conveying direction. Figure 1 An example of the connection between guide rail pair 35 and guide frame 34 is shown.

[0047] Alternatively, the guide elements 131 in the inlet guide mechanism 11 and the outlet guide mechanism 12 are connected to the same support structure or to different support structures respectively, thereby achieving support and fixation of the guide components. Figure 1 An example is shown in which the inlet guide mechanism 11 and the outlet guide mechanism 12 are respectively connected to the first support structure 141 and the second support structure 142.

[0048] Further, optionally, combined Figure 4 On the opposite surfaces of the two guiding elements of the inlet guiding mechanism 11 and / or the outlet guiding mechanism 12, there are first grooves 1311 that cooperate with the ribs 41 on the wing flat tube, thereby improving the stability of the guiding assembly.
