Description

Technical Field

[0001] This utility model relates to the field of cutting machinery technology, and in particular to a fully automatic hydraulic cutting machine for bipolar plates of batteries. Background Technology

[0002] A bipolar plate is a crucial component in batteries, especially in hydrogen fuel cells. Its primary function is to connect the individual battery cells (typically membrane electrode assemblies, MEAs) in series within the fuel cell stack, while also providing electrical conductivity and support for gas flow channels within the stack. The bipolar plate significantly impacts battery performance, reliability, and cost.

[0003] Cutting bipolar plates is a crucial step in the manufacturing process, especially in the production of battery systems such as hydrogen fuel cells and lithium batteries. Bipolar plates typically need to be cut to specific shapes and sizes to meet the design and structural requirements of the battery stack. The quality of the cut directly affects the battery's performance, sealing, gas flow channel design, and overall structural stability. However, existing cutting machines often leave some bipolar plates stuck together after cutting, making manual separation inefficient and labor-intensive. Furthermore, the sharp cut edges can easily cause cuts during manual operation.

[0004] To address the above issues, we propose a fully automatic hydraulic cutting machine for battery bipolar plates. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background technology by proposing a fully automatic hydraulic cutting machine for battery bipolar plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic battery bipolar plate hydraulic cutting machine, comprising two support bases, each of which has a reset mechanism at its upper end. The reset mechanism includes a U-shaped block, a slide rod fixedly connected to the U-shaped block, a slider slidably mounted on the slide rod, and a spring mounted on the slide rod. One end of the spring is fixedly connected to the U-shaped block and the other end is fixedly connected to the slider.

[0007] In the aforementioned fully automatic battery bipolar plate hydraulic cutting machine, a fixed plate is fixedly connected between the sliders in the two reset mechanisms, and a U-shaped frame is fixedly connected to the rear end of the fixed plate, with a rotating roller rotatably connected to the U-shaped frame.

[0008] In the aforementioned fully automatic battery bipolar plate hydraulic cutting machine, the upper ends of the two support bases are fixedly connected to a support frame, the front end of the support frame is fixedly connected to an extension plate, the extension plate is provided with a second electric telescopic rod with its telescopic end facing downward, and the telescopic end of the second electric telescopic rod is fixedly connected to a trapezoidal block.

[0009] In the aforementioned fully automatic battery bipolar plate hydraulic cutting machine, the fixed plate is provided with a first electric telescopic rod with its telescopic end facing downwards, and the telescopic end of the first electric telescopic rod is fixedly connected to a pressure plate.

[0010] In the aforementioned fully automatic battery bipolar plate hydraulic cutting machine, the support frame is equipped with two hydraulic cylinders with their telescopic ends pointing downwards. The telescopic ends of the two hydraulic cylinders are fixedly connected to a cutting block, and the lower end of the cutting block is fixedly connected to a cutting tool.

[0011] In the aforementioned fully automatic battery bipolar plate hydraulic cutting machine, a cutting platform is fixedly connected between the two support bases, and two support legs are fixedly connected to the lower ends of the two support bases.

[0012] Compared with existing technologies, the advantages of this fully automatic battery bipolar plate hydraulic cutting machine are:

[0013] This invention involves cutting and processing the bipolar plate, then moving the pressure plate forward via the fixed plate to move the portion of the bipolar plate that is being pressed down forward, thus separating the bipolar plates that are still partially bonded together. This avoids the risk of personnel being cut by the sharp cut edges of the bipolar plate during manual operation, and is both more efficient and safer. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3The fully automatic battery bipolar plate hydraulic cutting machine includes two support bases 1. Each support base 1 has a reset mechanism at its upper end. The reset mechanism includes a U-shaped block 2. A slide rod 3 is fixedly connected to the U-shaped block 2. A slider 4 is slidably sleeved on the slide rod 3. A spring 5 is sleeved on the slide rod 3. One end of the spring 5 is fixedly connected to the U-shaped block 2 and the other end is fixedly connected to the slider 4. A fixed plate 6 is fixedly connected between the sliders 4 in the two reset mechanisms. A U-shaped frame 9 is fixedly connected to the rear end of the fixed plate 6. A rotating roller 10 is rotatably connected to the U-shaped frame 9. A support frame 11 is fixedly connected to the upper end of the two support bases 1. An extension plate 12 is fixedly connected to the front end of the support frame 11. A second electric telescopic rod 13 with its telescopic end facing downward is provided on the extension plate 12. A trapezoidal block 14 is fixedly connected to the telescopic end of the second electric telescopic rod 13.

[0020] The second electric telescopic rod 13 moves the trapezoidal block 14 downward by extending its telescopic end downward. The inclined surface of the trapezoidal block 14 contacts the rotating roller 10 and pushes the rotating roller 10 forward, thereby driving the fixed plate 6 forward. After the telescopic end of the second electric telescopic rod 13 moves upward and causes the trapezoidal block 14 to separate from the rotating roller 10, the two sliders 4 are reset by the two springs 5, thereby driving the fixed plate 6 to reset.

[0021] The fixed plate 6 is provided with a first electric telescopic rod 7 with the telescopic end facing downward. The telescopic end of the first electric telescopic rod 7 is fixedly connected to a pressure plate 8. The support frame 11 is provided with two hydraulic cylinders 15 with the telescopic ends facing downward. The telescopic ends of the two hydraulic cylinders 15 are fixedly connected to a cutting block 16. The lower end of the cutting block 16 is fixedly connected to a cutting knife 17. The two support bases 1 are fixedly connected to a cutting platform 18. The lower ends of the two support bases 1 are fixedly connected to two support legs 19.

[0022] The bipolar plate is placed on the cutting platform 18. The first electric telescopic rod 7 drives the pressure plate 8 to move downward to press down on the bipolar plate. The two hydraulic cylinders 15 drive the cutting block 16 to descend. The cutting blade 17 cuts the bipolar plate. Then, the telescopic end of the second electric telescopic rod 13 drives the trapezoidal block 14 downward to move the fixing plate 6 forward. This causes the pressure plate 8 to move the part of the bipolar plate that it was pressing forward, separating the cut bipolar plate. Then, the two hydraulic cylinders 15 drive the cutting block 16 to rise. The telescopic end of the second electric telescopic rod 13 moves upward to drive the trapezoidal block 14 to rise. The fixing plate 6 is reset by the two reset mechanisms.

[0023] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
