Technical Field

[0001] This utility model belongs to the field of laser welding technology, specifically relating to a laser welding platform for conductive films in flow batteries. Background Technology

[0002] Flow batteries, proposed in 1974, are an electrochemical energy storage technology consisting of a stack and electrolyte. The positive and negative electrolytes are circulated separately, resulting in high capacity, long lifespan, and good safety, making them suitable for large-scale energy storage applications.

[0003] With the invention of flow batteries, battery system efficiency has improved, but this has also brought more challenges to conductive film welding. For example, conductive films are prone to deformation and oxidation during welding, and achieving precise positioning and stable clamping is difficult, leading to misalignment, incomplete welds, and other problems that affect the conductivity and structural integrity of the conductive film. Traditional welding platforms cannot meet the requirements for welding conductive films in flow batteries. Therefore, a new type of laser welding platform for conductive films in flow batteries is needed. Summary of the Invention

[0014] I.

[0027] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0028] Please see Figure 1-5 A laser welding platform for conductive films in flow batteries includes a base 1, a lead screw module 2 mounted on top of the base 1, and a worktable 3 linearly driven by the lead screw module 2. A glass stage 4, which covers the worktable 3, is fixedly mounted on top of the base 1. A gantry frame 7, which covers the glass stage 4, is linearly slidably mounted on top of the base 1. A three-axis laser module is mounted on top of the gantry frame 7, which, after being powered on, performs welding on key parts of the conductive film along a set trajectory. The gantry frame 7 is also provided with components for fixing it to a designated working position on the base 1 (not shown in the attached embodiment).

[0029] The lead screw module 2 includes a motor 201 fixedly mounted on a base 1. The output end of the motor 201 drives a lead screw 203 via a reducer 202. The lead screw 203 is threadedly connected to a seated nut 204, which is also fixedly connected to a cylinder support 301. A mounting base 205 is also fixedly mounted on the base 1, and the mounting base 205 is rotatably connected to the end of the lead screw 203 away from the motor 201 via a bearing. When the motor 201 of the lead screw module 2 is energized, it drives the lead screw 203 to rotate at a certain speed. The lead screw 203 drives the seated nut 204, which in turn drives the worktable 3 to a designated position.

[0030] The workbench 3 includes a cylinder support 301 linearly driven by a lead screw module 2. Several vertical cylinders 302 are fixedly mounted on the cylinder support 301, and the tops of the telescopic rods of all cylinders 302 are jointly and fixedly connected to a horizontal positioning plate support 303. A product positioning plate 304 is mounted on the top of the positioning plate support 303 and is fixed to the top of the positioning plate support 303 by hexagonal screws. In the embodiment shown in the attached drawings, six evenly distributed cylinders 302 are arranged on the workbench 3, pressing against the positioning plate support 303. The top of the product positioning plate 304 is milled with a three-dimensional positioning contour that matches the bottom of the product module 8, so as to accurately place the product module 8 at the welding station. The cylinder support 301 is equipped with an air distribution manifold 305 that controls all cylinders 302. The air distribution manifold 305 is connected to all cylinders 302 through air pipes, allowing all cylinders 302 to rise and fall synchronously.

[0031] The cylinder support 301 has several sliders 6 fixedly installed on both sides of its bottom, and the sliders 6 on the same side are slidably connected to a linear track 5 fixedly connected to the base 1. The lead screw module 2 drives the cylinder support 301 to move along the linear track 5.

[0032] The glass stage 4 includes a frame 401 fixedly connected to the base 1. A transparent glass plate 402 is installed at a square cutout in the top plate of the frame 401. At least four support blocks 403 are fixedly installed on the top plate of the frame 401, and all support blocks 403 together support and fix the glass plate 402. The four support blocks 403 support the four corners of the glass plate 402 respectively, and each support block 403 is installed on the top plate of the frame 401 by two bolts. The through-hole and edge notch of the glass plate 402 are used to avoid the bosses on the product module 8 so that the conductive film can adhere to the glass plate 402.

[0033] The gantry 7 has several sliders 6 fixedly installed on both sides of its bottom, and the sliders 6 on the same side are slidably connected to a straight track 5 fixedly connected to the base 1. After the gantry 7 is released from its fixed state in the working position, it can be pushed linearly along the straight track 5. The two sides of the gantry 7 are square frames spliced ​​from angle brackets and aluminum profiles, and the top of the two square frames are connected together by angle steel and steel plates.

[0034] Working principle:

[0035] During operation, the product module 8 containing the conductive film of the flow battery is placed on top of the product positioning plate 304. The product module 8 is precisely positioned at the welding station by the three-dimensional positioning contour. Then, the lead screw module 2 drives the worktable 3 to move to the bottom of the glass table 4. All cylinders 302 synchronously drive the positioning plate support 303 to rise, so that the conductive film of the product module 8 is tightly attached to the bottom surface of the glass plate 402 by the product positioning plate 304. Then, the three-axis laser module installed on the gantry 7 first slowly falls along the Z axis, keeping a distance of less than 10mm from the glass plate 402. According to the set X and Y axis trajectories, the bipolar plate, cover plate, sealing film (conductive film) and other parts of the product module 8 that need to be welded are welded by laser thermomelting. After the welding is completed, the positioning plate support 303 is lowered to the initial height, and the worktable 3 returns to the initial position to remove the welded product module 8.

[0036] When welding the conductive film of the new product module 8, the glass stage 4 and the product positioning plate 304 need to be replaced. The fixed state of the gantry 7 can be released, the gantry 7 can be pushed away from the glass stage 4, and then the glass stage 4 and the product positioning plate 304 can be removed.

[0037] If the glass plate 402 becomes stained and worn after long-term use, the gantry 7 can be released from its fixed position, the gantry 7 can be pushed away from the glass platform 4, and then all the supports 403 can be removed to replace the glass plate 402.

[0038] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
