Description

Technical Field

[0001] This utility model relates to the field of copper foil flexible connection welding technology, specifically a special device for copper foil flexible connection welding. Background Technology

[0002] Copper foil flexible connectors are made by pressing stacked copper foil sheets together, then using a molecular diffusion welder to heat them at high current and high temperature, causing them to split, melt, and be welded together. The product obtained by this method is a flexible connector sheet. This flexible connector sheet has good plasticity and high conductivity, and can withstand deformations such as extrusion, bending, and stretching under various harsh environments. At the same time, it can also carry a large current. Therefore, it is widely used in connections that require compact space, vibration resistance, and high current, such as conductive connections in high-power motors and battery packs of electric vehicles.

[0003] For example, patent publication number CN219131102U discloses a molecular diffusion welding machine, including: an upper heating head and a lower heating head arranged opposite each other, and a pressing device for driving the upper heating head and the lower heating head to press together, wherein: the upper heating head and the lower heating head are both electromagnetic induction heating heads, each including an iron-based metal heating element and an electromagnetic induction heating coil for heating the iron-based metal heating element, the iron-based metal heating element has a pressing surface that contacts the workpiece to be welded, and the pressing surface is covered with a coating layer composed of ceramic material.

[0004] Although the above-mentioned device solves the problem of short lifespan of heating elements, it still has the following drawbacks: In actual operation, workers will wrap the workpiece with a wet cloth to prevent high-temperature oxidation of the welding area. However, this operation method is cumbersome and the water cannot be continuously introduced into the wet cloth, which causes inconvenience. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a special device for welding copper foil flexible connections, so that the copper foil parts have the function of cooling with wet cloth during the welding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special device for welding flexible copper foil connections, comprising a welding machine body, a lower mold and an upper mold connected to the welding machine body, a clamping structure connected to the outer side of both the lower mold and the upper mold, the clamping structure comprising two side plates, a mounting box slidably connected to each of the two side plates, a wet cloth for clamping the upper and lower surfaces of the copper foil being connected between the opposite surfaces of the two mounting boxes, a water pipe being installed on the top of the mounting box, a pipe being installed on the top of the water pipe, and a rotating structure being connected to one of the side plates.

[0007] Furthermore, the rotating structure includes a bidirectional threaded rod, the bottom surface of which is rotatably connected to the side plate, a motor is mounted on the top surface of the side plate, the output end of the motor is fixedly connected to the bidirectional threaded rod, and sliders are fixedly connected to both ends of the two mounting boxes. The bidirectional threaded rod is threadedly connected to one end of the slider of the two mounting boxes.

[0008] Furthermore, two sliding grooves are provided on the side plate, and the slider is slidably connected to the sliding groove.

[0009] Furthermore, a fixing plate is fixedly connected to the top of the mounting box, and a slot is provided on the fixing plate. Insert plates are fixedly connected to both sides of the outer wall of the wet cloth, and the insert plates are inserted into the slots.

[0010] Furthermore, after the insert plate passes through the slot, two insert blocks are snapped into one end.

[0011] Furthermore, a connecting plate is fixedly connected between the two plug blocks.

[0012] Furthermore, the outer end of the insert has a chamfer.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves cooling of copper foil components during welding by using two mounting boxes, a wet cloth, and a water pipe.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1 to 5 As shown, a special device for welding flexible copper foil includes a welding machine body 1, a lower mold 2 and an upper mold 3 connected to the welding machine body 1. The outer sides of the lower mold 2 and the upper mold 3 are connected to clamping structures. The clamping structures include two side plates 4. Mounting boxes 11 are slidably connected to the two side plates 4. A wet cloth 5 for clamping the upper and lower surfaces of the copper foil is connected between the opposite surfaces of the two mounting boxes 11. A water pipe 13 is installed on the top of the mounting box 11. A pipe 6 is installed on the top of the water pipe 13. A rotating structure is connected to one of the side plates 4.

[0018] like Figure 1 As shown, the copper foil flexible connection welding device of this utility model is similar in structure to the existing molecular diffusion welding machine. For example, patent publication number CN219131102U discloses a molecular diffusion welding machine. The main improvement of this utility model is that it enables the copper foil to have a wet cloth cooling function during the welding process. Figures 1 to 5 As shown, in the copper foil flexible connection welding device of this utility model, one end of the copper foil is placed directly on the lower mold 2. After the upper mold 3 descends, the copper foil is welded. At this time, the rotating structure rotates, causing the two mounting boxes 11 to move closer to each other. The two mounting boxes 11 drive the corresponding wet cloths 5 to move closer to each other, clamping the copper foil. At this time, the pipe 6 supplies water through an external water supply device such as a water pump or water tank, so that the water pipe 13 supplies water to the mounting boxes 11, wetting the wet cloths 5. The wet cloths 5 are clamped on the copper foil, which can cool the copper foil.

[0019] By using two mounting boxes 11, a wet cloth 5, and a water pipe 13, the copper foil component being welded can be clamped and cooled. The water pipe 13 can continuously supply water to the wet cloth 5, eliminating the need for repeated handling and wetting, making the cooling operation of the copper foil component simpler and more convenient.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating structure includes a bidirectional threaded rod 14, the bottom surface of which is rotatably connected to the side plate 4. A motor 8 is mounted on the top surface of the side plate 4, and the output end of the motor 8 is fixedly connected to the bidirectional threaded rod 14. Slider 7 is fixedly connected to both ends of the two mounting boxes 11, and the bidirectional threaded rod 14 is threadedly connected to one end of the slider 7 of the two mounting boxes 11.

[0021] like Figure 2 and Figure 3As shown, two grooves 9 are provided on the side plate 4, and the slider 7 is slidably connected to the grooves 9.

[0022] Specifically, when the copper foil is being welded, the motor 8 rotates, which drives the bidirectional threaded rod 14 to rotate. When the bidirectional threaded rod 14 rotates, it is threadedly connected to the slider 7 at one end of the two mounting boxes 11. Under the restriction of the slide groove 9, the slider 7 can only move vertically, thereby enabling the mounting boxes 11 to move and clamp closer together, thus achieving the clamping of the two wet cloths 5.

[0023] like Figure 3 and Figure 4 As shown, a fixing plate 12 is fixedly connected to the top of the mounting box 11. A slot 15 is provided on the fixing plate 12. Insert plates 10 are fixedly connected to both sides of the outer wall of the wet cloth 5. The insert plates 10 are inserted into the slots 15.

[0024] like Figure 4 and Figure 5 As shown, after the insert plate 10 passes through the slot 15, two insert blocks 16 are snapped into one end.

[0025] Specifically, the wet cloth 5 will be damaged after a period of use. At this time, pull out the two plug blocks 16 located on the plug plate 10 to remove the plug plate 10 from the slot 15. After detachment, pull out the plug plate 10 to detach the wet cloth 5 from the mounting box 11 and replace it with a new wet cloth 5. This setting allows the wet cloth 5 to be replaced after it is damaged.

[0026] like Figure 5 As shown, a connecting plate 17 is fixedly connected between the two plugs 16. The connecting plate 17 facilitates the simultaneous removal of the two plugs 16 on the same side.

[0027] like Figure 5 As shown, the outer end of the plug 16 is chamfered. The chamfer makes it easier to plug in the plug 16.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
