[0046] It should be noted that the following detailed description is illustrative and aims to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention pertains.

[0047] In a typical embodiment of the present invention, as Figures 1-3 shown, an automatic device for flanging and hemming of a core tube is proposed, which includes a copper foil loading rack assembly 1, a core tube handling assembly 2, a core tube flanging and hemming assembly 3, and a core tube conveyor line 4.

[0048] As Figure 4 , Figure 5 and Figure 6 shown, the copper foil loading rack assembly 1 includes a frame 5, a speed reducer 6, a servo motor 7, a copper foil coil 8, copper foil 9, and an auxiliary clamping and fixing assembly 10. The frame 5 is the main installation and fixing structural member of the copper foil loading rack assembly 1, which is welded by carbon steel square tubes and carbon steel plates. The speed reducer 6 is connected to the frame 5 by screws. The output shaft of the servo motor 7 is directly connected to the tail slot of the speed reducer 6, and the servo motor 7 and the speed reducer 6 are connected by screws. Then, by operating the locking screw on the speed reducer 6, the clamp in the speed reducer 6 can hold the shaft of the servo motor 7 tightly. The copper foil coil 8 is full of copper foil 9, and the whole is in a disc shape, and is connected to the internal threaded hole on the output shaft of the speed reducer 6 by a locking screw. When the copper foil coil 8 is consumed, a new copper foil coil 8 can be quickly replaced by removing and installing the locking screw. When the servo motor 7 works, it will drive the speed reducer 6 and the copper foil coil 8 to rotate, and the string of copper foil 9 on the copper foil coil 8 will move downward, so as to achieve the function of loading the copper foil 9.

[0049] As Figures 11a-11b shown, the copper foil 9 is made of copper and is a solder for copper brazing. Its thickness is extremely thin, 0.1 - 0.15 mm. The structure of the copper foil 9 can be regarded as an extremely short tube. One end of the tube has a flanged edge 42, and two symmetrically distributed flanging wings 43 are prefabricated on the outer edge of the flanged edge. By bending and flanging the two flanging wings, the copper foil 9 is connected to the core tube 20 to form a whole. The copper foil 9 on the copper foil coil 8 is in a string, and two adjacent copper foils 9 are connected together through their respective flanging wings. There is a crease 44 and a central hole 45 between the adjacent flanging wings. Coupled with the extremely thin copper foil 9, the two copper foils 9 are easily separated under the application of external force.

[0050] As Figure 12As shown in the figure, the auxiliary clamping and fixing assembly 10 includes a parallel gripper 11, a left clamping jaw part 12 and a right clamping jaw part 13. The left clamping jaw part 12 and the right clamping jaw part 13 are connected to the parallel gripper 11 by screws; the opening and closing of the parallel gripper 11 drives the left clamping jaw part 12 and the right clamping jaw part 13 to complete the loosening and clamping actions. The function of the auxiliary clamping and fixing assembly 10 is to clamp the flanging and flanging fins of the copper foil 9 and assist in separating the two copper foils 9. The auxiliary clamping and fixing assembly 10 is connected to the frame 5 by screws, and the auxiliary clamping and fixing assembly 10 is located below the copper foil reel 8. Since the two ends of the core tube 20 both require copper foil 9 for flanging connection, two sets of copper foil reels 8 are symmetrically arranged on the copper foil loading rack assembly 1. Similarly, there are also two sets of the speed reducer 6, the servo motor 7 and the auxiliary clamping and fixing assembly 10 respectively.

[0051] As Figure 7 shown in the figure, the core tube handling assembly 2 includes an electric gripper 14, a core tube gripper 15, a pneumatic slide 16, a slide connecting plate 17, a lead screw electric cylinder 18, a slide fixing plate 19 and a core tube 20.

[0052] As Figure 13 、 Figure 7 、 Figure 14 shown in the figure, the two core tube grippers 15 are arranged oppositely, and the two core tube grippers 15 are connected to the two fingers of the electric gripper 14 by screws. When the electric gripper 14 works, it drives the two core tube grippers 15 to perform the clamping and loosening actions, that is, to complete the grasping and releasing tasks of the core tube 20; when the core tube gripper 15 grasps the core tube 20, it is necessary to ensure accurate positioning, reliable grasping and no loosening. Therefore, the contact part between the core tube gripper 15 and the core tube 20 is made into a V shape, that is, the clamping surface of the core tube gripper 15 is provided with a V-shaped groove 46. The V shape is suitable for positioning workpieces with a cylindrical outer surface. The inner contact surface of the V shape is processed into a knurled surface form (that is, anti-slip knurled marks 47 are provided on the surface of the V-shaped groove 46), which plays a role in anti-slip and increasing the friction force, ensuring reliable grasping of the core tube 20 without sliding. The electric gripper 14 is connected to the slide connecting plate 17 by screws. The slide connecting plate 17 is connected to the moving slide of the pneumatic slide 16 by screws; the pneumatic slide 16 is arranged to move up and down (move along the Z axis) and is connected to the slide fixing plate 19 by screws. When the pneumatic slide 16 works, it can drive the electric gripper 14 to grasp the core tube 20 to move up and down. The slide fixing plate 19 is connected to the moving platform of the lead screw electric cylinder 18 by screws. The lead screw electric cylinder 18 and the pneumatic slide 16 are arranged in a cross-intersecting form, that is, horizontally arranged (move along the X-axis direction). When the lead screw electric cylinder 18 works, it will drive the electric gripper 14 to grasp the core tube 20 to move horizontally. The lead screw electric cylinder 18 is connected to the frame 5 by screws, so that the core tube handling assembly 2 and the copper foil loading rack assembly 1 are connected into a whole.

[0053] AsFigure 8 and Figure 9 As shown in Figure 9 , the core tube flanging and hemming assembly 3 includes an electric slide table frame assembly 21, a flanging and clamping assembly 22, and a hemming assembly 23. Two sets of core tube flanging and hemming assemblies 3 are provided, and the two sets of core tube flanging and hemming assemblies 3 are respectively located below the two sets of copper foil reels 8 of the copper foil loading rack assembly 1.

[0054] As Figure 15 shown in Figure 15 , the electric slide table frame assembly 21 is composed of a fixed bottom plate 24, a support plate 25, an upper mounting plate 26, a material channel fixing plate 27, a copper foil material channel 28, an optical fiber sensor 29, a slide table fixing table 30, an electric slide table 31, an electric slide table connecting plate 32, and a core tube positioning member 33. The two support plates 25 are respectively connected to the fixed bottom plate 24 and the upper mounting plate 26 by screws; the material channel fixing plate 27 is connected to the upper mounting plate 26 by screws. The copper foil material channel 28 corresponds to the position between the copper foil reel 8 and the auxiliary clamping and fixing assembly 10. The copper foil material channel 28 is connected to the material channel fixing plate 27 by screws. The function of the copper foil material channel 28 is that when the copper foil reel 8 is loaded, the copper foil 9 can only be loaded along this material channel, and the position and loading posture are ensured to be accurate. Therefore, the upper end of the copper foil material channel 28 is a flared opening, which is convenient for the copper foil 9 to enter even if there is a deviation. The middle part is constricted, and the width and thickness are only limited to the passage of one copper foil 9. The bilateral gap is 0.2 mm, which ensures accurate positioning when the copper foil 9 is loaded. A through hole is opened at the lower end of the copper foil material channel 28, and a sensor mounting plate is welded opposite the through hole. The optical fiber sensor 29 is installed on the welding plate of the copper foil material channel 28. The detection light of the optical fiber sensor 29 is exactly opposite the through hole at the lower end of the copper foil material channel 28. When the copper foil 9 is loaded, there is a very small central hole in the middle of the flanging fins where two adjacent copper foils 9 are connected. The hole diameter is less than 2 mm. The accurate loading position is ensured by the optical fiber sensor 29 detecting the central hole and the precise movement of the servo motor 7. The slide table fixing table 30 is connected and installed on the fixed bottom plate 24 by screws, the electric slide table 31 is connected and fixed on the slide table fixing table 30 by screws, and the electric slide table connecting plate 32 is connected to the slide table of the electric slide table 31 by screws. The electric slide table 31 is driven by a motor, so it can control the slide table to move accurately in position and can also stop at any position within the stroke range.

[0055] The core tube positioning member 33 is installed on the electric slide table connecting plate 32. As Figure 18 shown in Figure 18 , a positioning table 48 for the copper foil 9 and the core tube 20 is machined at the front end of the core tube positioning member 33. When the copper foil 9 is loaded in place, the electric slide table 31 moves forward, and the positioning table 48 at the front end of the core tube positioning member 33 contacts the copper foil 9 to achieve positioning; in addition, through grooves 49 are machined at the corresponding parts of the front end of the core tube positioning member 33 and the two flanging fins of the copper foil 9. Its function is to avoid the flanging and hemming actuators during the hemming and flanging operations.

[0056] As Figure 16As shown in the figure, the flanging and clamping assembly 22 consists of a telescopic cylinder 34, a clamping gripper 35, a quick connector 36, a flange 37, and a flanging and clamping jaw 38. The telescopic cylinder 34 and the clamping gripper 35 are connected by the flange 37. The flanging and clamping jaw 38 is fixed to the two sliders of the clamping gripper 35 by screws. The quick connector 36 is directly tightened on the clamping gripper 35. The quick connector 36 is used to externally connect an air pipe, and the opening and closing of the air flow are used to control the loosening and clamping actions of the clamping gripper 35. The function of the flanging and clamping jaw 38 is to flange and clamp the flanging fins of the copper foil 9. The function of the telescopic cylinder 34 is to control the extension and retraction of the clamping gripper 35, facilitating the operation of the flanging and clamping jaw 38 on the copper foil 9 and avoiding the flanging station of the hemming to prevent interference with the hemming operation. There are two sets of flanging and clamping assemblies 22. One set is installed on the upper mounting plate 26, and the other set is installed on the fixed bottom plate 24. The two sets of flanging and clamping assemblies 22 are symmetrically distributed at both ends of the core tube positioning member 33.

[0057] As Figure 17 shown in the figure, the hemming assembly 23 consists of a hemming cylinder 39, a hemming punch 40, and a hemming cylinder fixing member 41. The hemming cylinder 39 is fixed to the hemming cylinder fixing member 41 by screws. The hemming punch 40 is fastened to the extension column of the hemming cylinder 39 by screws. The front end of the hemming punch 40 is processed into a blade form, and the initial hemming action of the flanging fins of the copper foil 9 is carried out using the punching force of the hemming cylinder 39. There are also two sets of hemming assemblies 23. One set is installed on the upper mounting plate 26, and the other set is installed on the fixed bottom plate 24. The two sets of hemming assemblies 23 are symmetrically distributed at both ends of the core tube positioning member 33. Since the initial state of the flanging fins of the copper foil 9 is flush with the flanging, to perform flanging, it is best to first hem the flanging fins to a certain angle and then perform flanging, which is easier. Therefore, the two sets of hemming assemblies 23 are arranged at an inclination of 64 degrees with the horizontal plane.

[0058] As Figure 10 shown in the figure, the core tube conveyor line 4 is the feeding device for the core tube 20. This part belongs to the assembly line part and is only shown schematically here. An existing conveyor line can be used. The core tube conveyor line 4 is located between the two sets of core tube flanging and hemming assemblies 3 and corresponds to the lower part of the core tube handling assembly 2.

[0059] As Figure 1 、 Figure 2 、 Figure 3 and Figure 14 shown in the figure, since the copper foil 9 needs to be flanged on both end faces of the core tube 20, two sets of core tube flanging and hemming assemblies 3 are provided in this core tube hemming and flanging device, symmetrically distributed on both sides of the core tube conveyor line 4. The conveying direction of the core tube conveyor line 4 is perpendicular to the two sets of core tube flanging and hemming assemblies 3 and the copper foil loading rack assembly 1. The copper foil loading rack assembly 1 spans above the core tube conveyor line 4.

[0060] The operation process of this core tube flanging and hemming device is as follows: The core tube conveyor line 4 conveys the core tube 20 to the grasping position and stops waiting; the servo motor 7 rotates to drive the copper foil reel 8 for feeding the copper foil 9. When the fiber optic sensor 29 detects the copper foil 9, the servo motor 7 precisely controls the copper foil 9 to reach the copper foil 9 feeding station and stops; then the auxiliary clamping and fixing component 10 works to clamp the flanging fin of the copper foil immediately before the last copper foil 9. The core tube handling component 2 starts to work. The lead screw electric cylinder 18 moves to the center directly above the core tube conveyor line 4. The pneumatic slide 16 extends downward to the grasping position of the conveyor line, and the electric gripper 14 clamps to grasp the core tube 20. Then the pneumatic slide 16 retracts upward to reach the alignment height with the copper foil 9 feeding. We set to first flange the right end face of the core tube 20. At this time, the lead screw electric cylinder 18 and the right electric slide 31 work simultaneously. The lead screw electric cylinder 18 moves to the right, that is, the core tube handling component 2 grasps the core tube 20 and approaches the copper foil 9 feeding position. The right electric slide 31 extends to the left, that is, the core tube positioning part 33 also approaches the copper foil 9 feeding position. To ensure that the core tube 20 and the core tube positioning part 33 reach the copper foil 9 simultaneously, the speeds of the lead screw electric cylinder 18 and the electric slide 31 need to be matched through program control. When the core tube 20 and the core tube positioning part 33 reach the copper foil 9 and are pressed tightly at the same time, the lead screw electric cylinder 18 and the electric slide 31 move to the right quickly at the same speed. Under the action of the external force to the right, the two connected copper foils 9 are separated. The lead screw electric cylinder 18 and the electric slide 31 continue to move to the right at a constant speed to the flanging and hemming station and stop, and continue to maintain the clamped state. Then, the two flanging components 23 work. The flanging cylinder 39 extends to drive the flanging punch 40 to quickly punch out, bending the flanging fin of the copper foil 9 to a certain slope. Subsequently, the flanging cylinder 39 retracts; the two sets of hemming clamping components 22 work. The telescopic cylinder 34 extends, and the hemming clamping claw 38 contacts the flanging fin of the copper foil 9 and presses the flanging fin for hemming. When the telescopic cylinder 34 extends in place, the clamping air claw 35 performs a clamping action to clamp the flanging fin. To ensure reliable hemming of the copper foil 9, the clamping air claw 35 can repeat the clamping action and hold for 1 - 2 seconds. After the hemming action, the telescopic cylinder 34 retracts. At this time, the hemming of the copper foil 9 on the right end face of the core tube 20 is completed. Next is to flange the copper foil 9 on the left end face of the core tube 20. The core tube handling component 2 starts to work. The lead screw electric cylinder 18 moves to the left, that is, the core tube handling component 2 grasps the core tube 20 and approaches the left copper foil 9 feeding position. The subsequent actions are the same as those in the right - hand flanging process and will not be elaborated. When the left - hand flanging is also completed, the core tube handling component 2 starts to work. The lead screw electric cylinder 18 moves to the center directly above the core tube conveyor line 4. The pneumatic slide 16 extends downward to the grasping position of the conveyor line, and the electric gripper 14 releases, placing the flanged core tube 20 onto the core tube conveyor line 4. The pneumatic slide 16 retracts upward, and the core tube conveyor line 4 continues to feed, and so on in a cycle.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
