Description

Technical Field

[0001] This utility model relates to an automated processing device for condenser fins and heat exchange tubes. Background Technology

[0002] Because the heat exchanger tubes and fins of the condenser are mass-produced, there are certain errors in their length. If these heat exchanger tubes and fins are used directly for assembly, it may lead to inconsistencies in the insertion depth of each heat exchanger tube into the manifold, which may even cause leakage in severe cases. Similarly, the errors between heat exchanger fins may also cause their ends to not be fully inserted into the corresponding sockets, which may lead to the fins falling off later. Therefore, it is necessary to precisely cut the length of the heat exchanger tubes and fins again before assembly to ensure that their lengths are consistent. Utility Model Content

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Combination Figure 1 and Figure 2 As shown, an automated processing device for condenser fins and heat exchange tubes includes a conveying mechanism, an ejection mechanism, a pressure plate mechanism, and a cutting mechanism. The conveying mechanism includes a conveyor belt 2 mounted on a frame 1. Heat exchange flat tube insertion slots 3 are evenly spaced on the conveyor belt 2, and the conveyor belt 2 between every two heat exchange flat tube insertion slots 3 forms a finned slot 4. The left and right sides of the conveyor belt 2 are respectively provided with guard plates 5. The push mechanism is located on the right side of the rear end of the conveyor belt 2. The push mechanism includes a push plate 6 that is telescopically connected to the right guard plate 5. The left guard plate 5 is provided with an opening 7 corresponding to the push plate 6. The cutting mechanism includes a cutting saw 8 that is moved back and forth and connected to the outer side of the left guard plate 5 frame 1. The pressure plate mechanism includes a pressure plate 9 that is lifted and lowered above the rear end of the conveyor belt 2.

[0019] The working principle of the above structure is as follows: multiple heat exchange flat tubes 10 are vertically inserted into the heat exchange flat tube insertion groove 3 in sequence, and fins 11 are placed between every two heat exchange flat tubes 10; each heat exchange flat tube 10 and fin 11 is moved backward under the drive of the conveyor belt 2 until it moves to the position of the corresponding push plate 6, at which point the conveyor belt 2 stops; at this time, the push plate 6 extends, pushing the left end of the corresponding heat exchange flat tube 10 and fin 11 out of the opening 7, and at this time the right end of each heat exchange flat tube 10 and fin 11 is pushed by the push plate 6. Alignment is achieved by lowering the pressure plate 9, which then moves downward to clamp each heat exchange flat tube 10 and fin 11 between the pressure plate 9 and the conveyor belt 2. The cutting saw 8 moves back and forth once to cut the right end of the heat exchange flat tube 10 and fin 11, making the right ends of each heat exchange flat tube 10 and fin 11 flush. After cutting, the pressure plate 9 is reset, and the processed heat exchange flat tube 10 and fin 11 are taken out from the opening 7 using a special fixture and transferred to the assembly workshop for condenser assembly.

[0020] The beneficial effects of the above structure are: the heat exchange flat tubes 10 and fins 11 of the condenser can be precisely cut in batches to ensure that the length of each heat exchange flat tube 10 and fin 11 is consistent. At the same time, the heat exchange flat tubes 10 and fins 11 have been spaced on the conveyor belt 2. After cutting, they can be transferred to the assembly workshop by special fixtures and assembled immediately, which also improves the processing efficiency of subsequent assembly.

[0021] In another embodiment, such as Figure 1 As shown, a waste discharge plate 12 is also provided on the frame 1 below the opening 7. The waste discharge plate 12 is located below the cutting mechanism. The waste of heat exchange flat tube 10 or fin 11 cut off by the cutting saw 8 is discharged into the collection tank along the waste discharge plate 12.

[0022] In another embodiment, such as Figure 1 As shown, a wall panel 13 is fixed to the outside of the right side guard plate 5, and a first cylinder 14 is fixed on the wall panel 13. The piston rod of the first cylinder 14 is connected to the push plate 6.

[0023] In another embodiment, such as Figure 1As shown, the front and rear ends of the right side of the push plate 6 are respectively fixed with first guide rods 15, and the wall plate 13 is provided with guide holes corresponding to the two first guide rods 15. The two first guide rods 15 pass through the corresponding guide holes to ensure the stability of the push plate 6 when it is displaced.

[0024] In another embodiment, a crossbeam is provided above the frame 1, and a second cylinder is fixed on the crossbeam. The piston rod of the second cylinder is connected to the pressure plate 9. A second guide rod 16 is provided on both sides of the pressure plate 9. The two second guide rods 16 pass through the corresponding guide holes on the crossbeam to ensure the stability of the pressure plate 9 when it is raised and lowered.

[0025] In another embodiment, such as Figure 2 As shown, the bottom of the pressure plate 9 is also provided with an elastic gasket 17 to avoid excessive compression of the heat exchange flat tube 10 and fins 11.

[0026] In another embodiment, the frame 1 is provided with a guide rail on its outer side, and a trolley is movably connected on the guide rail, with the cutting saw 8 fixed on the trolley.

[0027] In another embodiment, such as Figure 1 As shown, the saw blade of the cutting saw 8 is positioned close to the opening 7.

[0028] In another embodiment, the displacement stroke of the cutting saw 8 corresponds to the width of the first opening 7.

[0029] In another embodiment, two robotic arms are also included for feeding materials. The two robotic arms respectively clamp the heat exchange flat tube 10 and the fins 11 and place them onto the conveyor belt 2.
