Description

Technical Field

[0001] The invention relates to the field of heat exchanger production equipment, in particular to a preparation equipment for a fin plate heat exchanger. Background Art

[0002] In the manufacturing process of modern heat exchangers, the aluminum foil needs to be processed first, including punching, flanging and cutting to obtain qualified fins, and then the fins need to be transported and threaded. In the threading process, a certain number of fin plates need to be stacked, and then the baffles are staggered between the stacked fin plates to ensure that the fluid can follow the prescribed path and flow horizontally through the tube bundle multiple times, thereby significantly improving the heat transfer efficiency. Finally, the copper tube is passed through the arranged fins and baffles to complete the entire assembly process.

[0003] In the actual production process, the fins are not completely flat after being flanging, which makes it relatively difficult to stack and align them. In addition, the current tube threading process mainly relies on manual operation. Usually, workers need to pass the copper tubes through the fins one by one. This single-tube threading method is not only inefficient, but also time-consuming and prone to delays in production progress. Workers need to be highly focused and meticulous during the operation to ensure that the copper tube can pass through each fin hole smoothly to avoid bending or damage. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for use in the description of the embodiments. Obviously, the drawings described are only part of the embodiments of the present invention, not all of the embodiments, and those skilled in the art can also obtain other design solutions and drawings based on these drawings without creative work.

[0037] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0038] In the manufacturing process of modern heat exchangers, the aluminum foil needs to be processed first, including punching, flanging and cutting to obtain qualified fins, and then the fins need to be transported and threaded. In the threading process, a certain number of fin plates need to be stacked, and then the baffles are staggered between the stacked fin plates to ensure that the fluid can follow the prescribed path and flow horizontally through the tube bundle multiple times, thereby significantly improving the heat transfer efficiency. Finally, the copper tube is passed through the arranged fins and baffles to complete the entire assembly process.

[0039] In the actual production process, the fins are not completely flat after being flanging, which makes it relatively difficult to stack and align them. In addition, the current tube threading process mainly relies on manual operation. Usually, workers need to pass the copper tubes through the fins one by one. This single-tube threading method is not only inefficient, but also time-consuming and prone to delays in production progress. Workers need to be highly focused and meticulous during the operation to ensure that the copper tube can pass through each fin hole smoothly to avoid bending or damage.

[0040] To this end, a fin plate heat exchanger preparation device, referring to Figures 1 to 8 The invention comprises a frame 1, a punching mechanism 2, a feeding mechanism 3, a receiving mechanism 4, a suction mechanism 5, a stacking mechanism 6, a conveying mechanism 7 and a pipe-threading mechanism 8. The punching mechanism 2 is arranged on the frame 1. The punching mechanism 2 is used for continuously punching fins for punching, flanging and cutting. The feeding mechanism 3 is arranged at the feeding end of the punching mechanism 2. The feeding mechanism 3 is used for conveying aluminum foil raw materials to the punching mechanism 2. The receiving mechanism 4 is arranged at the discharging end of the punching mechanism 2. The receiving mechanism 4 is used for collecting the remaining aluminum foil processed by the punching mechanism 2. The raw material, the suction mechanism 5 is arranged on one side of the stamping mechanism 2, and the suction mechanism 5 is used to suck away the fins processed in the stamping mechanism 2, the stacking mechanism 6 is arranged on one side of the suction mechanism 5, and the stacking mechanism 6 is used to stack the fins sucked up by the suction mechanism 5, the conveying mechanism 7 is arranged on one side of the stacking mechanism 6, and the conveying mechanism 7 is used to convey the fin group stacked on the stacking mechanism 6, and the pipe-threading mechanism 8 is arranged on one side of the conveying mechanism 7, and the pipe-threading mechanism 8 is used to thread the fin group conveyed by the conveying mechanism 7.

[0041] In the actual production process, when it is necessary to process the fin plate heat exchanger, the rolled aluminum foil material is first placed on the feeding reel 301 of the feeding mechanism 3. After the aluminum foil is separated by the feeding roller 302, one end is inserted into the stamping mechanism 2. The feeding mechanism 3 and the receiving mechanism 4 operate synchronously, and the aluminum foil enters the stamping mechanism 2 in an orderly manner. The aluminum foil passes between the upper mold 201 and the lower mold 202, and the upper mold 201 processes the aluminum foil under the action of the hydraulic press. The punching station of the upper die 201 is provided with a punch, and the punching station of the lower die 202 is provided with an opening matching the punch. The punch moves downward under the action of the hydraulic press, contacts the aluminum foil and applies pressure to form the required holes. The excess material will be squeezed out by the punch and fall into the collection box 203 below the punching station through the opening on the lower die 202 for recycling. After the punching is completed, the aluminum foil moves to the next station, and the flanging station of the upper die 201 is provided with a flanging punch, and the flanging station of the lower die 202 is provided with a concave die matching the flanging punch. The punch exerts downward pressure under the action of the hydraulic press, and the concave die of the lower die 202 supports the aluminum foil. The flanging punch and the concave die act together on the aluminum foil to cause it to undergo plastic deformation, thereby obtaining a circle of vertical edges formed along the through hole. After the flanging is completed, the aluminum foil moves to the next station. The cutting station of the upper die 201 is provided with a cutter to cut the aluminum foil into a desired shape. The cutting station of the lower die 202 is provided with an opening matching the shape of the cutter. After the cutter cuts the aluminum foil, the formed fin 9 falls on the conveyor belt 204 below the cutting station through the opening on the lower die 202. Driven by the motor, the conveyor belt 204 moves the fin 9 to the end, and the cut aluminum foil enters the receiving mechanism 4, and is wound up and recycled by the receiving roller 402 and the receiving reel 401.

[0042] The fin 9 at the end of the conveyor belt 204 is sucked up by the suction assembly 506 and moved to the top of the stacking mechanism 6 through the first moving device 503 and the second moving device 505. After aligning the positioning rod 602 with the hole position of the fin, the suction assembly 506 releases the fin, and the fin 9 moves downward along the positioning rod 602 under the action of gravity to stack into a fin group 10. The optical coupling device 603 detects the height of the fin group. When it is stacked to a qualified height, the conveying mechanism 7 moves to the top of the fin group 10, and the outer rod 708 of the grabbing assembly 706 is aligned with the hole position of the fin 9. The expansion part 709 passes through the fin group 10 and extends from the bottom surface of the fin 9 at the bottom. The expansion cylinder 716 drives the inner rod 714 to move downward, thereby driving the push rod 715 to open the side rod 711 outward to prevent the fin group 10 from falling under the action of gravity. Subsequently, the grabbing assembly 706 moves to the top of the tube-threading mechanism 8 through the third moving device 703 and the fourth moving device 705. The copper tube 12 on the tube-threading mechanism 8 is aligned with the hole position of the fin 9, and the grab assembly 706 moves downward to allow the copper tube 12 to pass through the fin group 10 and extend from the top surface of the topmost fin 9. The expansion cylinder 716 drives the inner rod 714 to move upward, thereby driving the push rod 715 to retract the side rod 711 inward. The grab assembly 706 moves upward to extract the expansion part 709 from the fin group 10.

[0043] Next, the baffle moving mechanism 803 grabs the baffle 11 and moves it above the copper tube 12, and the hole position of the baffle 11 is aligned with the copper tube 12. The baffle moving mechanism 803 moves the baffle 11 downward to allow the copper tube 12 to pass through the baffle 11. After the next group of fin groups 10 are stacked, the conveying mechanism 7 repeats the above operation to assemble the second group of fin groups 10 onto the mounting seat. Subsequently, the baffle moving mechanism 803 grabs the baffle 11, turns it over through the rotating unit, and then moves the baffle 11 above the copper tube 12. The baffle moving mechanism 803 moves the baffle 11 downward to allow the copper tube 12 to pass through the baffle 11, thereby achieving the staggered assembly of the baffle 11. After the next group of fin groups 10 are stacked, the above process is repeated until the assembly is completed.

[0044] By providing a preparation device that integrates multiple functions, production efficiency and quality can be significantly improved. The device can automatically complete the processes of stamping, feeding, collecting, sucking, stacking, handling and pipe threading, reducing the tediousness and error rate of manual operation, thereby improving production efficiency, shortening the production cycle and reducing production costs. In addition, the use of automated equipment can also improve the working environment of workers, reduce labor intensity and improve production safety.

[0045] During the production process, if it is necessary to stop the machine to replenish the raw materials, this will have an adverse effect on the continuity of production, because the downtime will cause the interruption of the production line, thereby affecting the overall production efficiency and progress. Therefore, in one embodiment, the preparation equipment of the fin plate heat exchanger also includes a feeding mechanism 3 and a receiving mechanism 4, wherein the feeding mechanism 3 is arranged at the feeding end of the stamping mechanism 2, and the feeding mechanism 3 is used to convey the aluminum foil raw materials to the stamping mechanism 2, and the receiving mechanism 4 is arranged at the discharging end of the stamping mechanism 2, and the receiving mechanism 4 is used to collect the remaining aluminum foil raw materials processed by the stamping mechanism 2. The feeding mechanism 3 is arranged at the feeding end of the stamping mechanism 2 to ensure that the stamping mechanism will not stop due to the interruption of the raw material supply during the processing, thereby improving the production efficiency, and the receiving mechanism 4 is arranged at the discharging end of the stamping mechanism 2 to collect and organize the remaining aluminum foil raw materials generated by the stamping mechanism 2 during the processing, which can not only reduce the waste of raw materials, but also keep the work site clean and orderly.

[0046] In the process of continuous processing, the transfer of products and the recycling of waste materials will have a significant impact on the overall production efficiency. Therefore, in one embodiment, the stamping mechanism 2 includes an upper die 201 and a lower die 202, the upper die 201 and the lower die 202 are arranged relatively, the upper die 201 is provided with a stamping, flanging and cutting station, the lower die 202 is provided with a stamping, flanging and cutting station, the stamping mechanism 2 also includes a collection box 203 and a conveyor belt 204, the collection box 203 is arranged below the stamping station of the lower die 202, the collection box 203 is used to collect the thin sheets produced by stamping, the conveyor belt 204 is arranged below the cutting station of the lower die 202, and the conveyor belt 204 is used to transport the processed fins. The collection box 203 is arranged below the stamping station of the lower die 202 to collect the thin sheet materials produced during the stamping process, thereby avoiding the waste of materials and ensuring the cleanliness of the production site. The conveyor belt 204 is arranged below the cutting station to smoothly transport the cut fins to the next processing step, thereby improving the automation and efficiency of the entire production process.

[0047] Preferably, the conveyor belt 204 can be a roller conveyor line, a chain conveyor line or a belt conveyor line.

[0048] Preferably, a baffle is provided at the end of the conveyor belt 204, and the baffle is used to align the fins.

[0049] Since the plane of the fin is not completely flat after the flanging process, it is difficult to transfer the fin. Therefore, in one embodiment, the suction mechanism 5 includes a suction bracket 501, a first guide rail 502, a first moving device 503, a second guide rail 504, a second moving device 505, a suction assembly 506 and a negative pressure unit 507, wherein the suction bracket 501 is arranged on the ground, the first guide rail 502 is vertically arranged on the suction bracket 501, the first moving device 503 is slidably arranged on the first guide rail 502, the second guide rail 504 is horizontally arranged on the first moving device 503, the second moving device 505 is slidably arranged on the second guide rail 504, the suction assembly 506 is arranged on the second moving device 505, the negative pressure unit 507 is connected to the suction assembly 506 through an air pipe, and the suction assembly 506 is used to suck the fins on the conveyor belt 204. Through the design of double guide rails and double moving devices, the suction component 506 can be precisely positioned in both vertical and horizontal directions, thereby ensuring the accuracy of the suction operation. The suction component 506 can move independently in two directions, providing greater operating space and flexibility to meet the suction requirements of fins of different sizes and shapes. During the suction process of the fins, the negative pressure unit 507 can ensure the smooth conduct of the suction process, thereby greatly reducing the safety hazards caused by unstable suction. In summary, this improved suction mechanism 5 not only improves the suction accuracy and operational flexibility, but also significantly improves production efficiency and safety, providing a strong guarantee for the stable operation of the production line.

[0050] The fins may be misaligned during the stacking process. Therefore, in one embodiment, the stacking mechanism 6 includes a stacking bracket 601, a positioning rod 602, an optical coupling device 603 and an optical coupling bracket 604, wherein the positioning rod 602 is arranged on the stacking bracket 601, and a plurality of positioning rods 602 are arranged, wherein the positioning rod 602 corresponds to the hole position of the fin, and the positioning rod 602 is passed through the through hole of the fin, and the optical coupling bracket 604 is arranged on the stacking bracket 601, and the optical coupling device 603 is slidably arranged on the optical coupling bracket 604, and the optical coupling device 603 is used to detect the height of the fins stacked on the stacking mechanism 6. The positioning rod 602 corresponds to the hole position on the fin, ensuring that each positioning rod 602 can be accurately passed through the through hole of the fin. This design not only improves the convenience of assembly, but also greatly improves the accuracy and reliability of assembly. In this way, the positioning rod 602 can effectively position the fins, ensuring that each fin can be neatly stacked on the stacking bracket 601, avoiding misalignment or overlap between the fins, thereby improving the overall stacking efficiency and quality. The introduction of the optical coupling device 603 and the optical coupling bracket 604 improves the stacking accuracy and ensures uniform stacking of the fins, thereby improving the operating efficiency of the overall equipment. The non-contact detection method reduces damage to the fins and reduces production costs.

[0051] In order to ensure that the fin group can smoothly carry out the next operation during the production process, it is necessary to smoothly move the neatly stacked fin group to the position of the pipe threading mechanism 8. Therefore, in one embodiment, the transport mechanism 7 includes a transport bracket 701, a third guide rail 702, a third moving device 703, a fourth guide rail 704, a fourth moving device 705, and a grabbing assembly 706.

Through the design of double guide rails and double moving devices, precise positioning and independent movement in both vertical and horizontal directions are achieved. This not only improves the accuracy of the handling operation, but also enhances the flexibility and adaptability of the operation, so that the handling mechanism 7 can better meet the handling requirements of fins of various sizes and shapes.

[0052] The fin group needs to be grasped stably to avoid displacement or falling during transportation. Therefore, in one embodiment, the grasping assembly 706 includes a fixed plate 707 and an outer rod 708, the outer rod 708 is arranged on the bottom surface of the fixed plate 707, and a plurality of outer rods 708 are arranged, the outer rods 708 correspond to the hole positions of the fins, the outer rods 708 can pass through the through holes on the fins, and the lower ends of the outer rods 708 are provided with expansion parts 709 in a one-to-one correspondence. When the grasping assembly 706 is used in conjunction with the driving mechanism, the fin group can be automatically transported. The precise correspondence between the outer rod 708 and the fin hole positions ensures the accuracy of the limit during the grasping process, and the opening of the expansion part 709 provides additional support and protection during the transportation process. Such a design not only improves the transportation efficiency, but also ensures the safety and integrity of the heat dissipating fins during transportation.

[0053] The grabbing device needs to have the function of grabbing the heat sink fins and removing the heat sink fins. Therefore, in one embodiment, the expansion part 709 includes a sleeve 710 and two side rods 711, the side wall of the sleeve 710 is provided with two side grooves 712, the two side grooves 712 are symmetrically arranged, the two side rods 711 are arranged in the two side grooves 712 in a one-to-one correspondence, one end of the side rod 711 is rotatably connected to the side groove 712, a tensioning assembly 713 is arranged between the two side rods 711, and the tensioning assembly 713 includes an inner rod 714, two push rods 715 and an expansion cylinder 716, the inner rod 714 is arranged inside the outer rod 708, one end of the two push rods 715 are both rotatably connected to the inner rod 714, the other ends of the two push rods 715 are respectively rotatably connected to one side of the two side rods 711, and the telescopic part of the expansion cylinder 716 is fixedly connected to the inner rod 714 to drive the inner rod 714 to move up and down. When the fins are stacked together and aligned, the grabbing assembly 706 can move in coordination with the driving mechanism so that the expansion portion 709 is aligned with the corresponding through hole. The expansion portion 709 passes through the fin group and extends from the bottom surface of the bottommost fin. The expansion cylinder 716 drives the inner rod 714 to move downward, thereby driving the push rod 715 to open the side rod 711 outward. This design effectively prevents the fins from falling under the action of gravity, ensuring the safety and reliability of the handling process. After completing the handling task, the expansion cylinder 716 will drive the inner rod 714 to move upward, driving the push rod 715 to cause the side rod 711 to retract inward, so that the driving mechanism can pull the expansion portion 709 out of the fin group.

[0054] Preferably, the expansion cylinder 716 can be replaced by a hydraulic cylinder, an electric cylinder or a combination of rack and pinion.

[0055] The copper tubes need to be passed through the fin holes one by one to complete the assembly. Therefore, in one embodiment, the tube-threading mechanism 8 includes a mounting seat, which is set on the ground, and the mounting seat is provided with a mounting hole that matches the outer diameter of the copper tube, and the mounting hole corresponds to the hole position of the fin, and the mounting hole is used to place the copper tube. Through the precisely matched mounting holes, the copper tube and the fin are more tightly combined, the ease of operation during the installation process is significantly improved, and the installation time and labor costs are reduced. In addition, due to the precise correspondence between the mounting holes and the fin holes, errors that may occur during the installation process are avoided, thereby improving the overall quality and reliability of the product.

[0056] The baffles need to be installed in a staggered manner between the fin groups. Therefore, in one embodiment, the tube-threading mechanism 8 also includes a baffle material moving mechanism 803, and the baffle material moving mechanism 803 is arranged on the ground. The baffle material moving mechanism 803 includes a three-axis driving unit, a rotating unit and a clamping unit. The rotating unit is arranged on the three-axis driving unit, and the clamping unit is arranged on the clamping unit. The three-axis driving unit is used to drive the rotating unit to move in the X-axis, Y-axis and Z-axis directions. The rotating unit is used to rotate the clamping unit, and the clamping unit is used to clamp the baffles. The three-axis driving unit is responsible for providing power and control, driving the entire mechanism to move in the X-axis, Y-axis and Z-axis directions in three-dimensional space. The rotating unit is installed on the three-axis driving unit to realize the rotation of the clamping unit. Through the rotating unit, the clamping unit can rotate around different axes, thereby realizing the staggered assembly of the baffles, and realizing the efficient, accurate and automated handling and positioning of the baffles. It can significantly improve production efficiency, reduce the labor intensity of manual operation, and reduce potential safety risks. It can also improve the stability and reliability of the production process through automation and precise control.
