Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow battery processing technology, specifically to a laser welding device for a flow battery electrode frame and a proton exchange membrane plate frame. Background Technology
[0002] A flow battery is a type of rechargeable battery that stores and releases energy through ion exchange between two electrolytes. The key feature of a flow battery is that its energy storage medium is a liquid, called an electrolyte. These liquids are stored in two separate containers. During charging and discharging, the electrolyte circulates through the battery's electrolyte membrane, thereby completing the conversion between electrical energy and chemical energy.
[0003] The electrode frame and proton exchange membrane (PEM) plate frame are crucial components of a flow battery. The electrode frame secures and supports the electrode materials and acts as a current collector, while the PEM plate frame holds the proton exchange membrane and works with other battery components to form the battery's compartments. Flow batteries rely on electrolyte flow for operation; therefore, the electrode frame and PEM plate frame must have excellent sealing to prevent electrolyte leakage. During manufacturing, the electrode frame and PEM plate are laser-welded. To ensure welding precision and quality, the electrode frame often needs to be fixed in place. However, electrode frames come in various sizes and models, and changing the required electrode frame often necessitates changing the corresponding clamping device, significantly impacting work efficiency. Therefore, a laser welding device adaptable to various sizes is needed to solve this problem. Utility Model Content
[0004] The purpose of this invention is to solve the problem that traditional laser welding devices for flow battery electrode frames and proton exchange membrane frames require changing clamping devices when welding electrode frames of different sizes, thus affecting processing efficiency. The invention provides a laser welding device for flow battery electrode frames and proton exchange membrane frames.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a laser welding device for flow battery electrode frames and proton exchange membrane plate frames, comprising a frame and a laser welding assembly mounted on the frame. An electric push rod is mounted on the frame, and a push plate is fixedly connected to the extended end of the electric push rod. A slide rod is fixedly connected to the push plate, and the slide rod is slidably mounted on the frame. Two symmetrically arranged first clamping blocks are slidably mounted on the push plate, and two second clamping blocks are slidably connected to the frame. A limiting rod is fixedly connected to each of the second clamping blocks. A first limiting groove adapted to the limiting rod is formed on each of the first clamping blocks, and a second limiting groove adapted to the limiting rod is formed on the push plate. The limiting rod passes through the first clamping block and the push plate. The first and second clamping blocks are used to move and limit battery electrode frames of different sizes.
[0006] Preferably, a motor is fixedly connected to the frame, and a bidirectional screw is fixedly connected to the extended end of the motor.

The two swivels are rotatably connected to two second clamping blocks respectively. The bidirectional screw passes through the two second clamping blocks. When the bidirectional screw rotates, it drives the two second clamping blocks and the two first clamping blocks to move closer or further apart to adapt to battery electrode frames of different sizes.
[0007] Preferably, a first slider with a T-shaped cross-section is fixedly connected to one end of the first clamping block near the push plate. The push plate has a first groove that matches the size of the first slider. The first slider and the first groove are used to keep the first clamping block stable as it moves with the second clamping block.
[0008] Preferably, a second slider with an inverted T-shaped cross-section is fixedly connected to the bottom of the second clamping block, and a second slide groove adapted to the size of the second slider is provided on the frame.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figure 1-7 .
[0027] This utility model relates to a laser welding device for flow battery electrode frames and proton exchange membrane plate frames. It includes a frame 1 and a laser welding assembly 2 mounted on the frame 1. An electric push rod 6 is mounted on the frame 1, and a push plate 5 is fixedly connected to the extended end of the electric push rod 6. A slide rod 7 is fixedly connected to the push plate 5 and slidably mounted on the frame 1. Two symmetrically arranged first clamping blocks 3 are slidably mounted on the push plate 5, and two second clamping blocks 4 are slidably connected to the frame 1. A limiting rod 43 is fixedly connected to each second clamping block 4. A first limiting groove 44 adapted to the limiting rod 43 is formed on the first clamping block 3, and a second limiting groove 45 adapted to the limiting rod 43 is formed on the push plate 5. The limiting rod 43 passes through the first clamping blocks 3 and the push plate 5. The first clamping blocks 3 and the second clamping blocks 4 are used to move and limit battery electrode frames of different sizes. Adjusting the first clamping blocks 3 and the second clamping blocks 4 allows for clamping battery electrode frames of different sizes, solving the problem of needing to replace the clamping device.
[0028] Specifically, a motor 10 is fixedly connected to the frame 1. A bidirectional screw 8 is fixedly connected to the extended end of the motor 10. The end of the bidirectional screw 8 away from the motor 10 is rotatably connected to the frame 1. The two ends of the bidirectional screw 8 have reversed threads, and each end of the bidirectional screw 8 is threaded with a sleeve 9. A swivel 91 is fixedly connected to each of the two sleeves 9. The two swivels 91 are rotatably connected to two second clamping blocks 4, respectively. The bidirectional screw 8 passes through the two second clamping blocks 4. The bidirectional screw 8 is used to drive the two second clamping blocks 4 and the two first clamping blocks 3 to move closer or further apart when rotating, so as to adapt to battery electrode frames of different sizes, such as... Figure 7 As shown, the rotating ring 91 and the second clamping block 4 are rotatably connected, and the rotating ring 91 is fixed to the screw sleeve 9. Therefore, when the screw rotates, it will drive the screw sleeve 9 to rotate along the screw, causing the rotating ring 91 to move the second clamping block 4, thereby causing the two second clamping blocks 4 to move closer to each other or further away from each other.
[0029] It should be noted that, due to the setting of the limit rod 43, when the two clamping blocks move closer or further apart, the two first clamping blocks 3 will move closer or further apart. In other words, when the motor 10 rotates, it can simultaneously drive the two first clamping blocks 3 and the two second clamping blocks 4 to adjust the length of the electrode frame. When it is necessary to adjust the width of the electrode frame, the two first clamping blocks 3 can be adjusted simultaneously by simply retracting or extending the electric push rod 6.
[0030] In addition, a first slider 31 with a T-shaped cross section is fixedly connected to one end of the first clamping block 3 near the push plate 5. A first groove 32 adapted to the size of the first slider 31 is provided on the push plate 5. The first slider 31 and the first groove 32 are used to keep the first clamping block 3 stable during the movement of the second clamping block 4. Furthermore, a second slider 41 with an inverted T-shaped cross section is fixedly connected to the bottom of the second clamping block 4. A second groove 42 adapted to the size of the second slider 41 is provided on the frame 1. The second slider 41 and the second groove 42 are used to keep the two second clamping blocks 4 stable when they are close to or far from each other.
[0031] Furthermore, both the first clamping block 3 and the second clamping block 4 are arranged in an L-shape, and both the first clamping block 3 and the second clamping block 4 are fixedly connected with baffles 11 for pressing against the battery electrode frame. The height of the baffles 11 is higher than the height of the first clamping block 3 and the second clamping block 4. The higher the height of the baffles 11, the more electrode frame models it can be adapted to.
[0032] It should be noted that when adjusting the first clamping block 3, the second clamping block 4 will not move in the horizontal direction under the limiting action of the screw and the bidirectional screw 8. In other words, adjusting the width direction will not affect the length direction. The device can simultaneously adjust the electrode frame and the length and width directions by simultaneously adjusting the electric push rod 6 and the bidirectional screw 8.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
