[0002] Currently, in the welding area, after vacuum brazing, the core of the aluminum alloy plate-fin heat exchanger is manually moved from a welding cart to a welding platform for welding. When welding the back, products weighing less than 30 kg require one person to carry them, while products weighing 30 kg to 120 kg require 2 to 4 people to carry and flip them. The materials to be moved and flipped are placed in the appropriate position for welding (see the figure below), and the welding is carried out after the appropriate position requirements are met.

[0003] In the drying and spraying area, after the aluminum alloy plate-fin heat exchanger completes welding testing, a team of three people hangs it on the drying and spraying line. First, two people lift the product, which is lying flat on the pallet, flip it over, and adjust it to the appropriate angle. Then, they work together to lift the product under the hook. Finally, they hold it up while the third person hangs it on the drying and spraying line's hook. Finally, the two people release their arms, and the product is hung.

[0004] Currently, the method of transportation in the production process relies on manual labor. The process of manually transporting the entire core requires a lot of manual labor, which is not only cumbersome but also has high operational risks.

[0005] Therefore, there is still a need for an automatic flipping and clamping mechanism in the heat exchanger production process to solve the above problems. Utility Model Content

However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0026] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0027] Reference Figure 1-5 The present invention provides an automatic flipping and clamping mechanism 5 for heat exchanger production, characterized by comprising: a foundation pile 1, an extension piece 2, and a rotating clamping assembly 3. The foundation pile 1 is a rod-shaped structure, with its bottom fixed to the ground or a horizontal surface and its top connected to the rotating clamping assembly 3 via the extension piece 2.

[0028] The extension piece 2 is connected to the top of the pile 1, and the end of the extension piece 2 facing away from the pile 1 is the connection end. The extension length provides a sufficient rotation radius around the pile 1, allowing the rotary clamping assembly to rotate or move to a specified position after rotational clamping.

[0029] The rotating clamping assembly 3 includes a rotating mechanism 4 and a clamping mechanism 5. The clamping mechanism can clamp the core from both sides, and the core can be flipped at a certain angle under the action of the rotating mechanism 4. The rotating mechanism 4 includes a flipping driver 41 and a connecting member 42. The flipping driver 41 has a fixed end and a rotating output end. The fixed end of the flipping driver 41 is connected to the connecting end of the extension member 2 via the connecting member 42.

[0030] The clamping mechanism 5 includes: a telescopic driving member 51, a support frame 52 and a movable part 53. The support frame 52 is connected to the rotation output end, and the movable end of the telescopic driving member 51 is rotatably connected to the first end of the movable part 53. An extended first clamping part 521 is formed on one side of the opening for clamping on the support frame 52. The top of the support frame 52 is rotatably connected to a position close to the first end in the length direction of the movable part 53. When the movable end of the telescopic driving member 51 is pushed, the second end of the movable part 53 is used to cooperate with the first clamping part 521 to hold the core body. During operation, the extension piece 2 is first rotated a certain angle to move the clamping mechanism 5 to the position of the core body, and the gap between the second end and the first clamping part 521 is opened by driving the telescopic driving member 51, and then the core body is placed between the second end and the first clamping part 521, and the movable part 53 is rotated a certain angle by pulling the telescopic driving member 51, and then the second end and the first clamping part 521 clamp the core body, and then driven by the rotation output end of the rotating mechanism 4, it is rotated a certain angle and flipped to the expected core surface orientation, and moved to a certain position under the moving traction of the extension piece 2. There is no need to manually carry the core body and flip it, which greatly reduces the labor intensity of workers and simplifies the carrying steps.

[0031] Preferably, the connecting member 42 has a C-shaped connecting frame 421, and the rotary clamping assembly 3 further includes an angle driving member 6. The outer wall of the flip driving member 41 is further connected to an outer shell 43. One end of the shell of the angle driving member 6 is rotatably connected to one end of the C-shaped connecting frame 421, and the other end is rotatably connected to the outer shell 43 of the flip driving member 41, so that the outer shell 43 drives the tilt angle of the flip driving member 41. The angle driving member 6 is, for example, a pneumatic cylinder or a hydraulic cylinder. The driving member drives the entire flip driving member 41 to deflect at an angle. During operation, the angularly deflected flip driving member 41 drives the rotating mechanism 4 to deflect at a certain angle, thereby being able to clamp a variety of tilted cores. This has multiple applications and a wider range of applications, can significantly reduce the labor intensity of workers, and facilitates flipping.

[0032] Preferably, the second end of the movable portion 53 is further rotatably connected to a second supporting portion 531, and the second end is rotatably connected to the middle position of the second supporting portion 531 in the longitudinal direction. A buffer surface 532 is formed on the side of the second supporting portion 531 corresponding to the first supporting portion. The second supporting portion 531 is, for example, a strip-shaped component. When supporting the core, the movable second supporting portion 531 can cooperate with the fixed first supporting portion to highly conform to the core surface, thereby preventing the stress of supporting the core from being too extreme and concentrated in one place, which may cause deformation or even damage to the core.

[0033] The material of the buffer surface 532 is rubber, silicone or polyurethane. The buffer surface 532 can effectively buffer the clamping force during docking and prevent stress from damaging the core surface.

[0034] In one embodiment, a connection slot 7 is formed on the support frame 52 for receiving the telescopic drive member 51. A fixed shaft 71 is connected to the bottom of the connection slot 7 on the upper portion of the support frame 52. The bottom of the telescopic drive member 51 is fixedly connected to the fixed shaft 71. The connection slot 7 locks the fixed end of the telescopic drive member 51, preventing the core from becoming unstable and falling off due to the movement of the telescopic drive member 51 when the clamping mechanism moves, thereby reducing operational risks.

[0035] In one embodiment, the extension member 2 includes a first connecting rod 21 and a second connecting rod 22. The rod body of the first connecting rod 21 is rotatably connected to the top of the foundation pile 1. The first connecting rod is connected to the rotary clamping assembly 3 through the second connecting rod 22. The other end of the first connecting rod 21 is connected to the movable end of the fine-tuning telescopic member 23, and the fixed end of the fine-tuning telescopic member 23 is connected to the side wall of the foundation pile 1. The first connecting rod 21 and the second connecting rod 22 are sequentially connected through a rotational connection. When working, the working rotary clamping assembly 3 is provided with a swing position and a swing range, which can effectively transport the core to multiple positions with greater flexibility. The fine-tuning telescopic assembly can flip and offset the angle of the entire rotary clamping assembly, which can effectively pick up cores placed in multiple positions.

[0036] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
