Description

Technical Field

[0001] This utility model relates to the field of battery production and processing technology, specifically to a flow battery stack pressing device. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. Common batteries include dry cell batteries, flow batteries, and fuel cells. Taking a flow battery as an example, it consists of a stack unit, electrolyte, electrolyte storage and supply unit, and management and control unit. It is a high-performance battery that utilizes separate positive and negative electrolytes for independent circulation. It features high capacity, wide application range (environment), and long cycle life, and is therefore widely used in production and daily life. In the production and processing of flow batteries, after the stacks are stacked, they need to be pressed. The stacks are generally placed on a jig. After the stacks are stacked according to design requirements, the jig containing the stacks is transferred to a press for pressing. In traditional operations, this process is usually done manually. When the battery itself is large and heavy, auxiliary equipment such as hoisting mechanisms are needed to place the jig. The whole process is time-consuming, labor-intensive, inefficient, and prone to damage due to impact. Utility Model Content

Detailed Implementation

[0025] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1 to 6 The present invention provides a flow battery stack pressing device, comprising a machine base 1, a support frame 11 disposed on the machine base 1, a pressing mechanism 2 disposed on the support frame 11, a conveying mechanism 3 disposed on the machine base 1, a lifting mechanism 4 disposed on the machine base 1, a pressing fixture 5 disposed on the conveying mechanism 3, and a supporting mechanism 6 disposed on the machine base 1 for supporting the pressing fixture 5; the supporting mechanism 6 is located below the pressing mechanism 2.

[0028] The lifting mechanism 4 includes a lifting drive 41 connected to the machine base 1, a lifting plate 42 connected to the output end of the lifting drive 41, and a lifting seat 43 connected to the lifting plate 42. A cover plate 31 matching the lifting mechanism 4 is provided at a position corresponding to the conveying mechanism 3. The conveying mechanism 3 is connected to other stations on the battery production line, conveying the stacking fixture 5 to the area above the machine base 1. Initially, the lifting mechanism 4 lifts the conveying mechanism 3 upwards until the stacking fixture 5 reaches the top of the carrying mechanism 6, at which point the lifting drive 41 resets, allowing the stacking fixture 5 to fall onto the carrying mechanism 6.

[0029] The supporting mechanism 6 includes several supporting columns 61 mounted on the machine base 1, supporting seats 62 mounted on the supporting columns 61, and sensing components 63 mounted on the machine base 1. Each supporting seat 62 has a through hole 64 corresponding to the position of the sensing component 63. The sensing component 63 includes a sensing bracket and a sensor mounted on the sensing bracket. The sensor can be a fiber optic sensor, distance sensor, ultrasonic sensor, etc. The sensing component 63 can be used to sense whether the press fixture is in place. The height of the supporting seat 62 is higher than the height of the conveying mechanism 3 after it has descended, so that after the lifting mechanism 4 resets and the conveying mechanism 3 descends, the press fixture 5 can fall onto the supporting seat 62. The supporting mechanism 6 provides support, facilitating the application of pressure by the pressing mechanism 2.

[0030] The bearing seat 62 is provided with a positioning pin 65, and the press fixture 5 is provided with a corresponding positioning hole. The positioning pin 65 and the positioning hole cooperate to ensure that the press fixture 5 is accurately placed in the predetermined position. Thus, the pressing mechanism 2 can be accurately pressed into the predetermined position.

[0031] The pressing mechanism 2 includes a pressing drive 21 mounted on the support frame 11, a pressing plate 22 connected to the output end of the pressing drive 21, and a pressing fixture 23 mounted at the bottom of the pressing plate 22. In this embodiment, the pressing drive 21 uses a servo electric cylinder with a pressing output of 1000KN, pressure accuracy of ±0.2%FS, and displacement accuracy of ±0.02mm. The pressing output can be flexibly adjusted, and the pressing speed and holding time can be adjusted according to the product's process requirements during the pressing process to adapt to the processing needs of products of different specifications.

[0032] The machine base 1 is equipped with several guide rods 12, and the pressing plate 22 is movably connected to the guide rods 12. The guide rods 12 ensure that the pressing plate 22 moves more smoothly during the process.

[0033] The conveying mechanism 3 includes a first conveying chain 32 and a second conveying chain 33, a transmission rod 34 connected between the first conveying chain 32 and the second conveying chain 33, a cover plate 31 connected between the first conveying chain 32 and the second conveying chain 33, and a lifting mechanism 4 and a supporting mechanism 6 located between the first conveying chain 32 and the second conveying chain 33. The widths of the first conveying chain 32 and the second conveying chain 33 correspond to the bottom width of the reactor compaction fixture 5.

[0034] The flow battery stack pressing device includes a plugging mechanism 8 mounted on the machine base 1. The plugging mechanism 8 includes a plugging cylinder 81 connected to the machine base 1, a fixed base connected to the plugging cylinder 81, and a plurality of sealing tubes 82 mounted on the fixed base. The sealing tubes 82 are matched with corresponding interfaces of the flow battery stack and can be inserted into corresponding positions of the stack.

[0035] The support frame 11 is equipped with a safety light curtain 13. The safety light curtain 13 serves a protective function, stopping work when personnel enter the pressing operation area.

[0036] In this embodiment, two lifting mechanisms 4 are provided. The two lifting mechanisms 4 are respectively located near the two side edges of the machine platform 1, that is, near both ends of the conveying mechanism 3, to lift the conveying mechanism 3 from both ends, ensuring uniform force and making the lifting and moving process of the conveying mechanism 3 more stable.

[0037] In practice, the pressing fixture 5, which holds the flow battery stack, is conveyed into the conveying mechanism 3. The conveying mechanism 3 continues to convey the pressing fixture 5. When the pressing fixture 5 reaches above the supporting mechanism 6, the lifting mechanism 4 resets, causing the conveying mechanism 3 to descend. The pressing fixture 5 then contacts the supporting seat 62 of the supporting mechanism 6 and falls onto the supporting seat 62. At this point, the pressing tool 23 of the pressing mechanism 2 can move downward to begin pressing the battery stack. After pressing is completed, the lifting mechanism 4 lifts the conveying mechanism 3 again. During its ascent, the conveying mechanism 3 contacts the pressing fixture 5 and lifts it, causing the pressing fixture 5 to leave the supporting seat 62. At this point, the conveying mechanism 3 can send the pressing fixture 5 away, completing one pressing operation.

[0038] Example 2

[0039] This utility model provides a flow battery stack pressing device, including a machine base 1, a support frame 11 mounted on the machine base 1, a pressing mechanism 2 mounted on the support frame 11, a conveying mechanism 3 mounted on the machine base 1, a lifting mechanism 4 mounted on the machine base 1, a pressing fixture 5 mounted on the conveying mechanism 3, and a supporting mechanism 6 for supporting the pressing fixture 5 on the machine base 1; the supporting mechanism 6 is located below the pressing mechanism 2.

[0040] The lifting mechanism 4 includes a lifting drive 41 connected to the machine base 1, a lifting plate 42 connected to the output end of the lifting drive 41, and a lifting seat 43 connected to the lifting plate 42. A cover plate 31 matching the lifting mechanism 4 is provided at a position corresponding to the conveying mechanism 3. The conveying mechanism 3 is connected to other stations on the battery production line, conveying the stacking fixture 5 to the area above the machine base 1. Initially, the lifting mechanism 4 lifts the conveying mechanism 3 upwards until the stacking fixture 5 reaches the top of the carrying mechanism 6, at which point the lifting drive 41 resets, allowing the stacking fixture 5 to fall onto the carrying mechanism 6.

[0041] The supporting mechanism 6 includes several supporting columns 61 mounted on the machine base 1, supporting seats 62 mounted on the supporting columns 61, and sensing components 63 mounted on the machine base 1. Each supporting seat 62 has a through hole 64 corresponding to the position of the sensing component 63. The sensing component 63 includes a sensing bracket and a sensor mounted on the sensing bracket. The sensor can be a fiber optic sensor, distance sensor, ultrasonic sensor, etc. The sensing component 63 can be used to sense whether the press fixture is in place. The height of the supporting seat 62 is higher than the height of the conveying mechanism 3 after it has descended, so that after the lifting mechanism 4 resets and the conveying mechanism 3 descends, the press fixture 5 can fall onto the supporting seat 62. The supporting mechanism 6 provides support, facilitating the application of pressure by the pressing mechanism 2.

[0042] The bearing seat 62 is provided with a positioning pin 65, and the press fixture 5 is provided with a corresponding positioning hole. The positioning pin 65 and the positioning hole cooperate to ensure that the press fixture 5 is accurately placed in the predetermined position. Thus, the pressing mechanism 2 can be accurately pressed into the predetermined position.

[0043] The flow battery stack pressing device includes a blocking mechanism 7 mounted on the machine base 1. The blocking mechanism 7 includes a blocking drive 71 connected to the machine base 1 and a blocking seat 72 connected to the blocking drive 71. When the conveying mechanism 3 conveys the pressing fixture 5 to the area above the machine base 1, the blocking drive 71 drives the blocking seat 72 to rise, blocking the pressing fixture 5 and preventing it from moving further. Then, the lifting mechanism 4 can be reset, causing the conveying mechanism 3 to descend and the pressing fixture 5 to fall onto the supporting mechanism 6.

[0044] The pressing mechanism 2 includes a pressing drive 21 mounted on the support frame 11, a pressing plate 22 connected to the output end of the pressing drive 21, and a pressing fixture 23 mounted at the bottom of the pressing plate 22. In this embodiment, the pressing drive 21 uses a servo electric cylinder with a pressing output of 1000KN, pressure accuracy of ±0.2%FS, and displacement accuracy of ±0.02mm. The pressing output can be flexibly adjusted, and the pressing speed and holding time can be adjusted according to the product's process requirements during the pressing process to adapt to the processing needs of products of different specifications.

[0045] The machine base 1 is equipped with several guide rods 12, and the pressing plate 22 is movably connected to the guide rods 12. The guide rods 12 ensure that the pressing plate 22 moves more smoothly during the process.

[0046] The conveying mechanism 3 includes a first conveying chain 32 and a second conveying chain 33, a transmission rod 34 connected between the first conveying chain 32 and the second conveying chain 33, a cover plate 31 connected between the first conveying chain 32 and the second conveying chain 33, and a lifting mechanism 4 and a supporting mechanism 6 located between the first conveying chain 32 and the second conveying chain 33. The widths of the first conveying chain 32 and the second conveying chain 33 correspond to the bottom width of the reactor compaction fixture 5.

[0047] The flow battery stack pressing device includes a plugging mechanism 8 mounted on the machine base 1. The plugging mechanism 8 includes a plugging cylinder 81 connected to the machine base 1, a fixed base connected to the plugging cylinder 81, and a plurality of sealing tubes 82 mounted on the fixed base. The sealing tubes 82 are matched with corresponding interfaces of the flow battery stack and can be inserted into corresponding positions of the stack.

[0048] The support frame 11 is equipped with a safety light curtain 13. The safety light curtain 13 serves a protective function, stopping work when personnel enter the pressing operation area.

[0049] In practice, the pressing fixture 5, which holds the flow battery stack, is conveyed into the conveying mechanism 3. The conveying mechanism 3 continues to convey the pressing fixture 5. When the pressing fixture 5 reaches above the supporting mechanism 6, the lifting mechanism 4 resets, causing the conveying mechanism 3 to descend. The pressing fixture 5 then contacts the supporting seat 62 of the supporting mechanism 6 and falls onto the supporting seat 62. At this point, the pressing tool 23 of the pressing mechanism 2 can move downward to begin pressing the battery stack. After pressing is completed, the lifting mechanism 4 lifts the conveying mechanism 3 again. During its ascent, the conveying mechanism 3 contacts the pressing fixture 5 and lifts it, causing the pressing fixture 5 to leave the supporting seat 62. At this point, the conveying mechanism 3 can send the pressing fixture 5 away, completing one pressing operation.

[0050] In this embodiment, two lifting mechanisms 4 are provided. The two lifting mechanisms 4 are respectively located near the two side edges of the machine platform 1, that is, near both ends of the conveying mechanism 3, to lift the conveying mechanism 3 from both ends, ensuring uniform force and making the lifting and moving process of the conveying mechanism 3 more stable.
