Description

Technical Field

[0001] This invention relates to the field of heat exchanger processing technology, and in particular to a high-efficiency heat exchanger processing production line. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers mainly include plate heat exchangers and coil heat exchangers. The main component of a plate heat exchanger is the heat exchanger plate, which consists of multiple heat exchanger plates of the same specifications stacked together. The processing and assembly of heat exchanger plates in traditional plate heat exchangers typically involves feeding aluminum foil, punching, multi-step forming of the heat exchanger plates, and multi-step assembly of the heat exchanger plates. This process involves too many steps, requires a large amount of manual labor, and is inefficient.

[0003] An automated production line for plate heat recovery heat exchangers, disclosed in CN106180467A, includes a feeding device, a length detection device, a surface treatment device, and a slicing device arranged sequentially. An integrated forming device is also provided after the slicing device. While this production line can automatically produce heat exchangers, it lacks a precise positioning mechanism between the slicing device and the integrated forming device. The aluminum foil is simply pushed onto the forming device, making it impossible to guarantee the consistent position of each aluminum foil on the forming device. Misaligned aluminum foil affects the quality of the heat exchanger. Therefore, a high-efficiency heat exchanger processing production line needs to be designed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency heat exchanger processing production line. By setting up a positioning mechanism and a driving mechanism, it can achieve precise positioning of aluminum foil, avoiding the decline in the quality of the heat exchanger after molding due to inaccurate aluminum foil positioning, thereby improving the practicality of the device.

A motor 27 is installed on the inner wall of the placement groove. A drive shaft 26 is fixedly connected to the output end of the motor 27. The drive shaft 26 is connected to the second screw 14 through a first transmission mechanism.

[0027] The positioning table 5 is equipped with a drive mechanism for driving the workpiece unloading. The drive mechanism includes a first screw 13 rotatably connected to the side walls of the two gantry frames 10. A movable seat 11 is provided on the first screw 13. A movable crossbeam 8 is fixedly connected to the lower end of the movable seat 11. A first electric push rod 15 is fixedly connected to the lower end of the movable crossbeam 8. A first suction cup 9 is installed at the output end of the first electric push rod 15. A rotating rod 21 is rotatably connected to the inner wall of the placement slot. The rotating rod 21 is connected to the first screw 13 through a second transmission mechanism.

[0028] The first transmission mechanism includes a first gear 22 fixedly connected to the side wall of the rotating rod 21 and the second screw 14, a sleeve 24 sleeved on the side wall of the drive shaft 26, and a second gear 25 fixedly connected to the side wall of the sleeve 24, which can mesh with the first gear 22.

[0029] In this invention, a fixed plate 28 is fixedly connected to the side wall of the positioning platform 5. Two second electric push rods 23 are installed on the inner wall of the fixed plate 28. A movable plate 29 is rotatably connected to the side wall of the sleeve 24. The output end of the second electric push rod 23 is fixedly connected to the side wall of the movable plate 29. The inner ring cross-section of the sleeve 24 is rectangular, and the outer ring cross-section of the sleeve 24 is circular, so that the sleeve 24 can move left and right with the movable plate 29, thereby driving it to mesh with one of the first gears 22.

[0030] The second transmission mechanism includes a first sprocket fixedly connected to the side wall of the first screw 13, and a second sprocket fixedly connected to the side wall of the rotating rod 21. The first sprocket is connected to the second sprocket via a chain 20.

[0031] In this invention, a support plate 12 is fixedly connected to the side wall of the positioning table 5. The two support plates 12 are symmetrically distributed relative to the central axis of the mounting groove 18. A second crossbar that penetrates the sliding seat 33 is fixedly connected to the inner wall of the mounting groove 18. The support plate 12 is used to support the aluminum foil pushed out by the hydraulic slicing and forming machine 4.

[0032] In this invention, a first crossbar is provided through the side wall of the movable seat 11. Both ends of the first crossbar are fixedly connected to the side wall of the adjacent gantry frame 10. The first crossbar limits the movement of the movable seat 11, so that it can only move horizontally. The second crossbar has a similar function and serves to limit the movement.

[0033] In this invention, a camera 16 is installed at the lower end of the movable crossbeam 8, and an industrial computer 7 is installed on the side wall of the positioning platform 5. The industrial computer 7 contains a vision processing system, which is common in the industrial field and will not be described in detail.

[0034] In the initial state, the second suction cup 32 is located between the two support plates 12, and the output end of the first cylinder 34 retracts.

[0035] During use, aluminum foil is fed by feeding machine 1 and lubricated by oil tank 3. The hydraulic slicing and forming machine 4 slices it. The sheet aluminum foil is then pushed onto two support plates 12. The third electric push rod 31 is activated, and the output end of the third electric push rod 31 extends, causing the second suction cup 32 to move upward and contact the lower end of the aluminum foil. The second suction cup 32 then adsorbs the aluminum foil. The motor 27 is activated, and the output shaft of the motor 27 drives the drive shaft 26 to rotate. The drive shaft 26 drives the second gear 25 to rotate through the sleeve 24. The second gear 25 drives the second screw 14 to rotate by meshing with the first gear 22 at the lower end. Under the limit of the second crossbar, the sliding seat 33 drives the adsorbed aluminum foil to move to the left. When the pressure sensor 30 shows a pressure value, the motor 27 is turned off. Then the motor 27 is turned on again, the output shaft of the motor 27 reverses (stepper motor), and the second suction cup 32 moves to the right to reset.

[0036] Then the first cylinder 34 is activated. The output end of the first cylinder 34 extends and moves forward through the clamping plate 17 to press the aluminum foil against the side wall of the clamping plate 17 of the second cylinder 35. In the process, the aluminum foil is accurately positioned, avoiding the decline in the quality of the heat exchanger after molding due to inaccurate positioning of the aluminum foil.

[0037] In addition, the aluminum foil is captured by camera 16, and the industrial computer 7 performs flaw detection on the image. When the aluminum foil is damaged, the second cylinder 35 can be activated. The output end of the second cylinder 35 retracts, and the first cylinder 34 is activated again. The output end of the first cylinder 34 extends again to push the aluminum foil out of the positioning table 5. The process realizes automatic sorting of aluminum foil, which can further ensure the quality of the heat exchanger after it is formed.

[0038] After the aluminum foil is pushed out, the output end of the first cylinder 34 retracts to its initial state. Subsequent aluminum foils continue to be positioned according to the above steps. After positioning, the output end of the first cylinder 34 retracts, the second electric push rod 23 is activated, the output end of the second electric push rod 23 retracts, the second gear 25 meshes with the upper first gear 22, the motor 27 is activated, the rotating rod 21 rotates, the rotating rod 21 drives the first screw 13 to rotate through the chain 20, the moving seat 11 drives the moving beam 8 to move to the left. When the first suction cup 9 is above the center of the aluminum foil, the motor 27 is turned off, the first electric push rod 15 is activated, the first suction cup 9 moves downward and picks up the aluminum foil, the output end of the first electric push rod 15 retracts, the motor 27 is activated, after the aluminum foil moves to the receiving table 6, it is assembled by the receiving table 6, the motor 27 is activated and the output shaft reverses, the moving seat 11 is reset, then the output end of the second electric push rod 23 extends, the second gear 25 meshes with the lower first gear 22.
