[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1, Reference Figures 1 to 20The cooler fin automatic unloading machine shown in the figure comprises a chassis 1, a conveying mechanism 2 is arranged on one side of the chassis 1, a fin 3 is arranged on the upper end of the conveying mechanism 2, a receiving mechanism 4 for receiving the fin 3 and curing the surface paint thereof is arranged inside the chassis 1 and on one side of the conveying mechanism 2, a unloading mechanism 5 for unloading the fin 3 inside the receiving mechanism 4 is arranged inside the chassis 1 and on one side of the receiving mechanism 4, and a feeding mechanism 6 is arranged inside the chassis 1 and on one side of the receiving mechanism 4; The receiving mechanism 4 includes an exhaust assembly 42 installed inside the chassis 1, a conveying assembly 41 for conveying the fins 3 is arranged inside the exhaust assembly 42, and a placement assembly 43 for receiving the fins 3 is arranged inside the conveying assembly 41; The feeding mechanism 6 includes a spacer assembly 62 rotatably mounted inside the chassis 1 , and a plurality of mounting assemblies 61 distributed in a ring array and used for placing the fins 3 in layers are arranged inside the spacer assembly 62 .

[0024] It is worth noting that when in use, the fin 3 is conveyed to the conveying mechanism 2 after being rolled, the conveying mechanism 2 conveys the fin 3 to the conveying component 41, the conveying component 41 conveys the fin 3 to the placement component 43, and when the fin 3 falls on the placement component 43, the exhaust component 42 sprays hot air to the fin 3 through the placement component 43, and the hot air is guided to blow on the surface of the fin 3 through the placement component 43 and the exhaust component 42; When the fins 3 fall onto the placement component 43 and the paint on the surface is further cured by hot air, the unloading mechanism 5 absorbs the fins 3 on the placement component 43 and transports them to the installation component 61. When the unloading mechanism 5 absorbs the fins 3 for transportation, it also sprays hot air on the surface of the fins 3. When the unloading mechanism 5 places the fins 3 on the installation component 61, the spacer component 62 rotates to adjust the position of the installation component 61. When the unloading mechanism 5 places the fins 3 again, the fins 3 placed on the installation component 61 are placed in a stepped shape, so that the placed fins 3 do not overlap. When the fins 3 are placed on the installation component 61, the spacer component 62 sprays hot air and blows it on the surface of the fins 3 again through the installation component 61, so that the paint on the surface of the fins 3 is completely cured.

[0025] Among them, the fin 3 is subjected to multiple hot air treatments on the placement component 43, during the conveyance of the unloading mechanism 5, and on the installation component 61, and the paint on the surface of the fin 3 is fully heated and cured, thereby improving the adhesion, hardness and durability of the coating, and the multi-level curing treatment ensures the stability and consistency of the paint quality; The rotation adjustment function of the spacer assembly 62 ensures that the fins 3 are arranged in a stepped shape on the mounting assembly 61, avoiding overlap and contact between the fins, thereby reducing damage or deformation caused by collision or extrusion. Although the entire process involves multiple hot air treatments, since these treatments are performed on a specific area, namely the surface of the fin 3, compared with overall heating, it can utilize energy more efficiently and reduce unnecessary energy consumption.

[0026] Embodiment 2: Based on the material receiving mechanism 4 proposed in Embodiment 1, this embodiment provides a further embodiment of a conveying component 41, an exhaust component 42 and a placement component 43.

[0027] The conveying assembly 41 includes a driving motor 411 installed on the upper part of the chassis 1, and a support rod 413 is arranged at the output end of the driving motor 411. The outer surface of the support rod 413 is provided with a plurality of shrapnel disks 414 distributed at equal intervals. The outer surfaces of the plurality of shrapnel disks 414 are commonly provided with a hole tube 412, and the hole tube 412 is close to one side of the conveying mechanism 2.

[0028] It is worth mentioning that the driving motor 411 drives the support rod 413 to rotate through the output shaft, the support rod 413 drives the shrapnel disk 414 to rotate, and the shrapnel disk 414 drives the orifice tube 412 to rotate. When the fin 3 is transported to the position of the orifice tube 412 through the conveying mechanism 2, the orifice tube 412 rotates to convey the fin 3 to the surface of the placement component 43, and the surface of the orifice tube 412 is hollowed out, and the hot air ejected from the exhaust component 42 will blow onto the surface of the fin 3 through the orifice tube 412.

[0029] Among them, through the precise control of the driving motor 411, the orifice tube 412 can rotate at a stable speed and angle, thereby ensuring that the fin 3 can be accurately moved from the conveying mechanism 2 to the specified position of the placement component 43. The hollow design of the orifice tube 412 allows the hot air ejected from the exhaust component 42 to pass through the orifice tube evenly and blow directly onto the surface of the fin 3, ensuring sufficient contact between the hot air and the fin surface, thereby improving the curing efficiency and uniformity of the coating.

[0030] The placement component 43 includes a baffle 431, which is fixedly mounted on the inner wall of the mounting frame 421. Arc guide plates 434 are arranged on both sides of the baffle 431. The two arc guide plates 434 are both located inside the semi-duct 424. A plurality of air guide holes 432 distributed in a rectangular array are provided on the outer surface of the baffle 431. A plurality of arc inclined plates 433 distributed at equal intervals are provided on the upper end of the baffle 431.

[0031] The exhaust assembly 42 includes a mounting frame 421 mounted on the upper end of the chassis 1, two half-ducts 424 are symmetrically arranged on both sides of the upper end of the mounting frame 421, arc plates 425 are arranged inside the two half-ducts 424, a cone disk 423 is arranged at the bottom of the mounting frame 421, and a vent hole 422 communicating with the interior of the cone disk 423 is arranged on one side of the outer surface of the cone disk 423.

[0032] Among them, after the hole tube 412 is transported to the arc-shaped plate 433, the fin 3 falling on the arc-shaped plate 433 will slide forward because the shape of the arc-shaped plate 433 is arc-shaped. The fin 3 is pushed faster by the subsequent hole tube 412, so that the fin 3 quickly passes through the arc-shaped plate 433 and falls onto the arc-shaped plate 433 as a whole. The arc-shaped plate 433 is designed to be plastic with a smooth surface, which will not affect the sliding of the fin 3. After the fin 3 falls on the arc-shaped plate 433, the hot air sprayed out from the vent hole 422 is sprayed out through the cone disk 423, and the cone disk 423 is designed to be conical so that the hot air diffuses from the middle to the surroundings. The hot air will pass through the air guide hole 432 and then be guided by the arc-shaped plate 433 to blow on the bottom surface of the fin 3; After the hot air is guided by the cone disk 423 and blows on the surface of the baffle 431, it will be blown into the semi-duct 424 through the guidance of the arc guide plate 434, and then the hot air is guided by the arc plate 425 to blow to the upper surface of the fin 3. Since the arc plate 425 is designed to be located on both sides of the mounting frame 421 and the fin 3, the hot air guided by the arc plate 425 will blow on the surface of the fin 3, thereby further curing the paint on the surface of the fin 3.

[0033] Among them, the arc design and smooth surface of the arc-shaped plate 433 ensure that the fin 3 can slide quickly and smoothly to the predetermined position, reducing production delays caused by friction or jamming. The conical design of the cone disk 423 allows the hot air to diffuse from the middle to the surroundings. Through the guidance of the air guide holes 432 and the arc-shaped plate 433, the hot air can be evenly blown on the bottom surface of the fin 3, ensuring that the bottom coating of the fin 3 is fully heated and cured. On the other hand, the hot air is guided by the semi-duct 424 and the arc plate 425 and blows to the upper surface of the fin 3. Since the arc plate 425 is located on both sides of the fin 3, the hot air can fully cover the upper surface of the fin, further enhancing the curing effect of the coating. The comprehensive and uniform heating method ensures the uniform curing of the coating on the surface of the fin 3, avoiding coating quality problems caused by uneven heating, such as bubbling and peeling.

[0034] A plurality of arc-slanted pieces 433 are provided at the upper end of the baffle 431, and the arc-slanted piece 433 is located between every two arc-slanted pieces 433, and a wave piece 435 is provided between every two arc-slanted pieces 433. The wave piece 435 is fixedly installed at the upper end of the arc-slanted piece 433, and the outer surfaces of the plurality of wave pieces 435 are provided with a plurality of holes 436 distributed at equal intervals.

[0035] The cross section of the wave plate 435 is in a wave shape, and the baffle 431 is located above the cone disk 423 .

[0036] Among them, when the hot air is blown out through the air guide hole 432, it will also pass through the arc-slanted sheet 433, and the arc-slanted sheet 433 is symmetrically arranged from the central axis of the baffle 431, so it can guide the hot air to blow continuously toward the middle, and guide the hot air to blow toward the fin 3 placed on the arc-slanted sheet 433, and the wave sheet 435 is designed in a wave shape to assist the sliding of the fin 3, and can further guide the flow of the hot air to blow on the surface of the fin 3 through the cavity 436, which can reduce the contact area of ​​the fin 3 when it is placed and increase the contact area with the hot air.

[0037] Among them, the arc-slanted sheet 433 is symmetrically arranged from the central axis, which can guide the hot air to blow continuously toward the middle, ensuring that the hot air directly and concentratedly acts on the fin 3 placed on the arc-slanted sheet 433, thereby improving the utilization rate of the hot air and reducing the heat loss. The wave-shaped design of the wave sheet 435 not only assists the sliding of the fin 3, but also further guides the flow direction of the hot air through its special structure. Under the guidance of the wave sheet, the hot air can cover the surface of the fin 3 more evenly, reducing the heating blind area and improving the curing uniformity of the coating.

[0038] The hole 436 on the corrugated sheet not only serves as a channel for hot air to flow through, but also further refines the distribution of the hot air. The hole 436 allows the hot air to more directly contact the bottom and sides of the fin 3, thereby increasing the contact area between the hot air and the fin surface. The design of the corrugated sheet also reduces the direct contact area between the fin 3 and the arc-shaped sheet 433 when the fin 3 is placed. The design of reducing the contact area helps to avoid local overheating or deformation of the fin due to long-term contact with the high-temperature surface, and also improves the stability of the fin during the heating process.

[0039] Embodiment 3: Based on the unloading mechanism 5 and the feeding mechanism 6 proposed in Embodiment 1, this embodiment provides a further embodiment of the unloading mechanism 5, the mounting assembly 61 and the spacer assembly 62.

[0040] The unloading mechanism 5 includes a mechanical arm 51, which is fixedly mounted on the upper end of the chassis 1. A shaft 52 is arranged inside the mechanical arm 51, an electromagnetic suction cup 55 is arranged at the bottom of the shaft 52, an air guide disc 54 is arranged on the outer surface of the shaft 52 and located on the upper part of the electromagnetic suction cup 55, and an air supply pipe 53 connected to the interior of the air guide disc 54 is arranged on the outer surface of the air guide disc 54.

[0041] It is worth noting that after the fin 3 falls onto the receiving mechanism 4, the mechanical arm 51 rotates to change the position of the shaft 52, and the shaft 52 moves up and down to energize the electromagnetic suction cup 55 to adsorb the fin 3. Then, when the electromagnetic suction cup 55 adsorbs the fin 3, the air supply pipe 53 sprays hot air, which is guided by the air guide disc 54 and blows on the surface of the fin 3. The design of the air guide disc 54 is Figure 4 The shape shown can change the flow direction of the gas to blow on the surface of the fin 3.

[0042] The spacer assembly 62 includes a chassis 621, which is connected to the output end of the driving motor inside the chassis 1. A plurality of spacers 622 distributed at equal intervals are arranged at the upper end of the chassis 621. A barrel cover 623 is arranged in the middle of the upper end of the chassis 621. A plurality of mounting holes 625 distributed in a circular array are opened on the outer surface of the barrel cover 623. An air pipe 624 communicating with the interior of the barrel cover 623 is installed at the upper end of the barrel cover 623 through a sealing bearing. An air barrier 626 is arranged at the bottom of the outer surface of the air pipe 624, and the air barrier 626 is located inside the barrel cover 623.

[0043] Among them, when the tube cover 623 rotates, the positions of the air pipe 624 and the air barrier 626 will not change, because the air pipe 624 is connected to the tube cover 623 through a sealed bearing, and the air barrier 626 is set to prevent hot air from being discharged through other mounting holes 625, so that the hot air is only blown into the ladder block 613 where the fins 3 are placed, ensuring that the hot air is fully utilized.

[0044] The mounting assembly 61 includes a ladder block 613, which is mounted on the upper end of the chassis 621 and inside the mounting hole 625. A plurality of rectangular grooves 612 are provided on one side of the ladder block 613, a plurality of exhaust holes 614 are provided on the upper end of the ladder block 613, and a plurality of microporous sheets 611 are provided on the ladder block 613.

[0045] When the electromagnetic suction cup 55 absorbs the fin 3 and moves to the position of the ladder block 613, the fin 3 falls on the ladder block 613, and the air pipe 624 blows out hot air into the tube cover 623, and the hot air enters the ladder block 613 through the mounting hole 625, and then is discharged through the rectangular groove 612, and the rectangular groove 612 is opened on one side of the ladder block 613, and the fin 3 that falls on the microporous sheet 611 is located on one side of the rectangular groove 612, so the hot air discharged through the rectangular groove 612 blows on the surface of the fin 3 and enters the hot air of the ladder block 613. The hot air will also be discharged through the exhaust hole 614, and then discharged through the microporous sheet 611. The microporous sheet 611 has a mesh design that allows gas to circulate. After the fins 3 are placed, the chassis 621 rotates slowly. The rotation of the chassis 621 is adjusted by numerical control. When the unloading mechanism 5 places the fins 3 on the ladder block 613 again, the placed fins 3 are stacked in a trapezoidal design, so that the surfaces of the two placed fins 3 will not touch each other, ensuring that the paint on the surface of the fins 3 will not be damaged during curing and ensuring that the two fins 3 will not stick together.

[0046] Among them, the electromagnetic suction cup 55 can accurately absorb and move the fin 3 from the conveyor line to the position of the ladder block 613, so as to realize the precise positioning and stacking of the fin. The fin 3 is designed to be stacked in a trapezoidal shape on the ladder block 613, thereby ensuring that the surfaces of two adjacent fins will not directly contact each other, thus avoiding damage or sticking problems caused by mutual contact of the fins during the paint curing process, and ensuring the integrity of the fin surface and the curing quality of the coating.

[0047] The hot air blown out of the air pipe 624 enters the ladder block 613 through the tube cover 623 and the mounting hole 625, and is directly blown to the surface of the fin 3 through the rectangular groove 612, so that the hot air can act on the fin surface efficiently and accelerate the curing process of the coating. At the same time, the hot air is discharged through the exhaust hole 614 and the microporous sheet 611, forming a good hot air circulation and improving the utilization rate of heat.

[0048] Since the hot air is blown evenly toward the surface of the fin 3 through the rectangular groove 612, it is ensured that the coating can be evenly heated and cured. The uniform heating method helps to reduce the temperature gradient during the coating curing process and avoids coating quality problems caused by local overheating or overcooling.

[0049] The slow rotation and numerical control adjustment function of the chassis 621 make the entire stacking and heating process more flexible and efficient. When the unloading mechanism 5 places the fins 3 on the ladder block 613 again, a new stacking operation can be completed quickly.

[0050] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
