Description

Technical Field

[0001] This utility model relates to the field of battery production and processing technology, specifically to a high-precision fuel cell stack stacking fixture. 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, lead-acid batteries, lithium batteries, sodium batteries, flow batteries, and fuel cells. A fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through an electrochemical reaction. Fuel cells convert the Gibbs free energy portion of the fuel's chemical energy into electrical energy through an electrochemical reaction, without being limited by the Carnot cycle effect, thus resulting in high efficiency. In a fuel cell, the stack is the core component that converts the chemical energy of fuel and oxidant into electrical energy, and its performance directly determines the efficiency, lifespan, and application scenarios of the fuel cell system. During fuel cell manufacturing, various components need to be stacked sequentially to form the stack. To ensure accurate stacking, a stack fixture is used to position the stack components during the internal stacking process. However, current stack fixtures are easily affected by external influences and can wobble. The portion of the stack extending beyond the casing can easily shift due to this wobble, affecting the stacking accuracy. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Reference Figures 1 to 4 This utility model provides a high-precision fuel cell stack stacking fixture, including a base 1, a main frame 2 disposed on the base 1, several supporting components 3 disposed on the main frame 2, several locking components 4 disposed on the inner side of the main frame 2, and several clamping components 5 disposed on the top of the main frame 2. The main frame 2 includes two long-side fixing brackets 21 and two short-side fixing brackets 22 vertically disposed on the base 1, which form a rectangular space for accommodating the fuel cell stack fixture. The fuel cell stack fixture is placed in the rectangular space, wherein the supporting components 3 support the fuel cell stack fixture from the bottom, the locking components 4 limit the fuel cell stack fixture in the horizontal direction, and the clamping components 5 limit the fuel cell stack fixture from the top.

[0022] The load-bearing component 3 is connected between two long-side fixing frames 21. Both the long-side fixing frame 21 and the short-side fixing frame 22 have locking components 4 on their inner sides, and both have clamping components 5 on their tops. The long-side fixing frame 21 and the short-side fixing frame 22 can be locked together using fasteners.

[0023] The positioning assembly 4 includes a positioning base 41 connected to the main frame 2 and a positioning member 42 connected to the positioning base 41. The positioning base 41 has a groove, and the positioning member 42 is connected to the groove. The positioning member 42 is a slender rod. When the fuel cell stack fixture is placed into the rectangular space inside the main frame 2, the positioning member 42 and the fuel cell stack fixture are in close contact, thereby limiting the horizontal movement of the fuel cell stack fixture and preventing it from shaking during use. Furthermore, the size of the positioning member 42 can be adaptively adjusted according to the fuel cell stack fixture being fixed. For example, when the fuel cell stack fixture is small, the size of the positioning member 42 or the mounting base can be increased (for example, in this embodiment, the cross-section of the positioning member 42 is rectangular, and the length of the cross-section can be increased).

[0024] Both the long-side fixing bracket 21 and the short-side fixing bracket 22 are provided with mounting grooves 23 corresponding to the positions of the card holder 41. The groove walls of the mounting grooves 23 are provided with a plurality of first oblong holes 24, and the card holder 41 is provided with first mounting holes 25 that mate with the first oblong holes 24. The first oblong holes 24 are arranged along a preset vertical direction, reserving a certain amount of space for the position adjustment of the card holder 41. During assembly, fasteners pass through the first oblong holes 24 and connect to the first mounting holes 25, thereby achieving a stable connection between the card holder 41 and the long-side fixing bracket 21 / short-side fixing bracket 22.

[0025] The top of the locking member 42 is provided with a limiting groove 43. The limiting groove 43 is set according to the specific structure of the fuel cell stack fixture. The top edge of the fuel cell stack fixture can be inserted into the limiting groove 43, thereby limiting the position of the top edge of the fuel cell stack fixture in the horizontal direction and further preventing the fuel cell stack fixture from shaking.

[0026] The clamping assembly 5 includes a clamping bracket 51 disposed on the top of the main frame 2, and a locking member 52 disposed on the clamping bracket 51. The specific shape of the clamping bracket 51 can be designed according to the specifications of the fuel cell stack fixture. After the fuel cell stack fixture is placed into the rectangular space inside the main frame 2, tightening the locking member 52 will bring the locking member 52 into contact with the fuel cell stack fixture, thereby locking the fuel cell stack fixture vertically. In addition, the number and position of the clamping assemblies 5 can also be adapted to the specific structure of the fuel cell stack fixture.

[0027] The supporting assembly 3 includes a supporting rod 31 and two fixing seats 32 respectively connected to both ends of the supporting rod 31. The two fixing seats 32 are respectively connected to two long-side fixing frames 21. The long-side fixing frame 21 is provided with a through hole 26 that mates with the supporting rod 31. The fixing seat 32 is connected to the outside of the long-side fixing frame 21, and the end of the supporting rod 31 is inserted into the through hole 26 and connected to the fixing seat 32.

[0028] The fixing base 32 is provided with a second oblong hole 33, and the long side fixing bracket 21 is provided with a second mounting hole 27 that mates with the second oblong hole 33. The second oblong hole 33 is set along a preset vertical direction, which reserves a certain space for the position adjustment of the fixing base 32. During assembly, fasteners are connected to the second mounting hole 27 through the second oblong hole 33, thereby achieving a stable connection between the fixing base 32 and the long side fixing bracket 21.

[0029] The base 1 is rectangular, and rollers 11 are provided at each of the four corners of the base 1. The rollers 11 can guide the jig during the jig transfer process, ensuring that the jig moves smoothly along the preset transfer path. The top surface of the base 1 is also provided with several lifting rings 12. There are four lifting rings 12 arranged in a rectangular shape to ensure even force distribution. During the production process, the entire jig can be lifted by lifting equipment such as cranes, realizing rapid transfer. This not only improves the convenience and efficiency of jig transfer, but also avoids jig damage or safety hazards that may be caused by manual handling.

[0030] Reinforcing members 13 are provided on the base 1 at the four corners corresponding to the main frame 2. In this embodiment, the reinforcing members 13 are L-shaped, with their two perpendicular sides tightly fitted and connected to the outer sides of the long side fixing frame 21 and the short side fixing frame 22, respectively, thereby surrounding the corner areas of the main frame 2. The four reinforcing members 13 can completely enclose the main frame 2. The reinforcing members 13 are fixed to the top surface of the base 1 by fasteners, which can further improve the stability of the connection between the base 1 and the main frame 2 and ensure the reliability of the overall device for long-term use.

[0031] In this embodiment, two locking components 4 are provided on the inner side of the long side fixing frame 21, and one locking component 4 is provided on the inner side of the short side fixing frame 22. The six locking components 4 surround the fuel cell stack fixture, limiting the fuel cell stack fixture from all sides. Two bearing components 3 are provided. In actual use, a support plate is placed on the two bearing components 3, and the fuel cell stack fixture is placed on the support plate.

[0032] In practical use, first select the appropriate locking component 4 and clamping component 5 according to the structure of the fuel cell stack fixture, and adjust the positions of the locking component 4, clamping component 5 (if the clamping component 5 will cause interference when placing the fuel cell stack fixture, it may not be necessary to fix the clamping component 5 first), and bearing component 3. First, place the support plate on the bearing component 3, and then place the fuel cell stack fixture into the rectangular space inside the main frame 2, so that the locking component 42 and the fuel cell stack fixture are in close contact. Then, tighten the locking component 52 of the clamping component 5 to lock the fuel cell stack fixture from above, thereby limiting the fuel cell stack fixture in both the horizontal and vertical directions, preventing the fuel cell stack fixture from shaking during stacking, transfer, etc., ensuring the progress of fuel cell stack stacking, and guaranteeing product quality.
