Description

Technical Field

[0001] This utility model relates to the field of induction welding equipment, and in particular to an automated copper foil induction welding equipment. Background Technology

[0002] In various electrical equipment, multi-layered composite metals, such as copper foil bonded to other metal substrates, are required. Flux is added between the copper foil and the metal substrate, and welding is achieved by heating the flux. However, current equipment faces challenges such as the difficulty of welding long metal plates and uneven heating leading to poor welding results. Specifically, the flux needs to reach its melting point during heating to effectively connect the copper foil and the metal substrate. However, when handling long metal plates, the considerable length makes transportation inconvenient and also makes it difficult for the equipment to ensure uniform heating throughout the welding area, seriously affecting welding quality and product reliability. Therefore, it is necessary to develop an automated copper foil induction welding device to solve the above problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 4As shown, an automated copper foil induction welding device includes a frame 1, a conveying mechanism 2, a mounting bracket 3, a first pressing mechanism 4, a second pressing mechanism 5, and an induction heating component 6. The conveying mechanism 2 includes a first conveyor belt 21, a second conveyor belt 22, a conveying roller 23, and a rotary drive component 24. The first conveyor belt 21, the second conveyor belt 22, and the conveying roller 23 are all rotatably mounted on the frame 1. The first conveyor belt 21 and the second conveyor belt 22 correspond to the left and right sides of the conveying roller 23, respectively. The rotary drive component 24 is fixed on the frame 1 and is drivenly connected to the first conveyor belt 21, the second conveyor belt 22, and the conveying roller 23. The mounting bracket 3 is fixed on the frame 1. The first pressing mechanism 4 is fixed on the left side of the mounting bracket 3 and above the first conveyor belt 21, and the second pressing mechanism 5 is fixed on the right side of the mounting bracket 3 and above the conveyor roller 23. The induction heating assembly 6 includes a first induction coil 61, a second induction coil 62 and a heating control box 63. The first induction coil 61 and the second induction coil 62 are respectively located on the left and right sides of the conveyor roller 23. The first induction coil 61 has a first material passage hole in the middle, and the second induction coil 62 has a second material passage hole in the middle. Both the first induction coil 61 and the second induction coil 62 are electrically connected to the heating control box 63.

[0018] A long strip of copper foil and a metal substrate are placed on the first conveyor belt 21. Flux has been pre-added between the copper foil and the metal substrate. The rotary drive assembly 24 simultaneously drives the first conveyor belt 21, the second conveyor belt 22, and the conveyor roller 23 to rotate clockwise. The first conveyor belt 21 conveys the workpiece to the right. The first pressing mechanism 4 presses the workpiece against the first conveyor belt 21 with a certain pressure to make the workpiece more stable when it is conveyed to the right. The workpiece first passes through the middle of the first induction coil 61, then passes between the conveyor roller 23 and the second pressing mechanism 5, and then passes through the middle of the second induction coil 62. The second pressing mechanism 5 presses the workpiece against the conveyor roller 23 with a certain pressure to improve its conveying stability and positional accuracy. The heating control box 63 controls the first induction coil 61 and the second induction coil 62 to induction heat the workpiece, thereby melting the flux and achieving welding. After welding, the workpiece is continued to be conveyed to the next process by the second conveyor belt 22. The advantage of this design is that it can stably transport long strip-shaped metal workpieces, allowing the flux to heat up more evenly during induction heating, and the flux to melt fully, thereby improving welding efficiency and quality.

[0019] The first pressing mechanism 4 includes a mounting plate 41, a vertical slide 42, a cylinder 43, a movable plate 44, a slider 45, a first connecting arm 46, and a first pressure roller 47. The mounting plate 41 is fixed on the left side of the mounting bracket 3. The vertical slide 42 and the cylinder 43 are both fixed on the mounting plate 41. The slider 45 is fixed on the right side of the movable plate 44 and is slidably connected to the vertical slide 42. The movable plate 44 is fixedly connected to the power output end of the cylinder 43. The first connecting arm 46 is fixed on the front and rear sides of the movable plate 44. The front and rear ends of the first pressure roller 47 are rotatably mounted on two sets of first connecting arms 46, and the first pressure roller 47 corresponds to the top of the first conveyor belt 21.

[0020] The cylinder 43 drives the movable plate 44 to move downward, while the slider 45 moves downward along the vertical slide table 42, making the movable plate 44 more stable when it moves. As the movable plate 44 descends, the first pressure roller 47 presses the workpiece onto the first conveyor belt 21.

[0021] The second pressing mechanism 5 includes a connecting frame 51, a swing frame 52, a rotating shaft 53, an elastic element 54, a second connecting arm 55, and a second pressure roller 56. The connecting frame 51 is fixed on the right side of the mounting bracket 3. The rotating shaft 53 passes through the middle of the swing frame 52. The swing frame 52 is rotatably mounted on the connecting frame 51 via the rotating shaft 53. The upper end of the elastic element 54 is fixed on the connecting frame 51 with the elastic end facing down. The elastic end of the elastic element 54 abuts against the upper end face on the left side of the swing frame 52. The upper end of the second connecting arm 55 is fixed on the right side of the swing frame 52 and its position is adjustable in the left and right directions. Two sets of second connecting arms 55 are provided and correspond to the front and rear sides of the swing frame 52, respectively. The front and rear ends of the second pressure roller 56 are rotatably mounted on the lower ends of the two sets of second connecting arms 55, respectively. The second pressure roller 56 is made of non-metallic material and corresponds to the upper part of the conveying roller 23.

[0022] The swing frame 52 can swing on the connecting frame 51. The second pressure roller 56 presses on the workpiece by gravity. Before the equipment starts running, the right end of the swing frame 52 needs to be lifted up to facilitate the workpiece to pass through. Then, when the right end of the swing frame 52 is released, the left end of the swing frame 52 contacts the elastic end of the elastic element 54, thereby buffering the swing of the swing frame 52.

[0023] This design also includes a cooling mechanism 7, which includes a cooling control box 71, a cooling protective cover 72, and a cooling duct. The cooling protective cover 72 is fixed on the frame 1 and surrounds the upper outer periphery of the second conveyor belt 22. A cooling cavity is formed between the cooling protective cover 72 and the second conveyor belt 22. One end of the cooling duct is fixedly installed in the cooling cavity, and the other end is connected to the cooling control box 71.

[0024] The welded workpiece can be cooled naturally on the second conveyor belt 22, or the cooling efficiency can be improved by introducing cooling gas into the cooling protective cover 72. The cooling gas can be nitrogen or argon, which can prevent metal oxidation.

[0025] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
