[0037] As a preamble to the embodiments of this application, in the production process of solid oxide fuel cells (hereinafter referred to as fuel cells), it is often necessary to cut fuel cells of different sizes. Common cutting methods include mechanical cutting, waterjet cutting, electrical discharge machining (EDM) cutting, and laser cutting. Due to factors such as precision, cost, automation level, and process flexibility, laser cutting is more suitable for the process flow of solid oxide fuel cells. To achieve process precision, continuity, and consistency, laser cutting fixtures are typically used to assist in the cutting process. Currently, existing laser cutting fixtures are usually only suitable for fuel cells of specific sizes. When cutting fuel cells of different sizes, different fixtures need to be changed, which not only increases production costs but also reduces production efficiency. Furthermore, traditional cutting fixtures do not provide good fixation for fuel cells and are prone to displacement during the cutting process, affecting cutting precision.
[0038] In view of this, embodiments of this application provide a cutting fixture, which aims to solve at least one of the above-mentioned technical problems.
[0039] Please see Figure 1 As shown in the embodiment of this application, a cutting fixture includes a body 10 and a first fixture assembly 20. The body 10 has N first suction holes 100, where N is an integer greater than or equal to 2. N of the N first suction holes 100 are arranged in an array, and n is a positive integer less than or equal to N. For example, the value of n can be 2, 3, 4, 5, etc.
[0040] The first fixture assembly 20 is supported on the body 10 and has a plurality of second suction holes 200 arranged in an array. At least one second suction hole 200 corresponds to and is interconnected with a first suction hole 100. The first fixture assembly 20 is supported by the upper surface of the body 10 and includes M first fixture modules 201 that are assembled together, where M is an integer greater than or equal to 2. The second suction holes 200 are disposed on the first fixture modules 201. The orthographic projections of m of the M first fixture modules 201 on the body 10 have different orthographic projection shapes, and m is a positive integer less than or equal to M, where m can be 2, 3, 4, 5, etc.
[0041] For example, the first fixture module 201 may include a polygon module 201c with more sides, wherein the orthographic projection of the polygon module onto the body is a polygon shape, such as a triangle, rectangle, square, pentagon, hexagon, or a shape with more sides. The first fixture module 201 may include one or more rectangular modules 201a and one or more sector modules 201b; furthermore, among the multiple rectangular modules 201a, at least two rectangular modules 201a have different lengths or widths in their orthographic projections onto the body 10, or both length and width may be different. For example, the orthographic projection of one or more rectangular modules 201a onto the body 10 may be a square, and the orthographic projection of another or more rectangular modules 201a onto the body 10 may be a larger or smaller square; similarly, the orthographic projection of one or more rectangular modules 201a onto the body 10 may be a rectangle, and the orthographic projection of another or more rectangular modules 201a onto the body 10 may be a larger or smaller rectangle. The orthographic projection of the sector module 201b onto the body 10 may be a semicircle or a quarter circle, etc. The radius of the sector module 201b can be larger or smaller. The orthographic projection of the first fixture module 201 onto the body 10 can also be an irregular structure, such as a ring, a pentagon, or other shapes, with the specific shape adjusted according to actual needs.
[0042] For example, such as Figure 6 As shown, the first fixture assembly 20 includes two square rectangular modules 201a, one of which has a second air intake hole 200, and the other two rectangular modules 201a each have a total of nine second air intake holes 200 in a 3*3 pattern.
[0043] It also includes 9 rectangular modules 201a, including 2 modules with 12 second air intake holes 200 each (1*12), 2 modules with 8 second air intake holes 200 each (8*1), 2 modules with 12 second air intake holes 200 each (4*3), 15 second air intake holes 200 each (5*3), 10 second air intake holes 200 each (5*2), 2 second air intake holes 200 each (2*1), 1 irregularly shaped module with 11 second air intake holes 200, 1 irregularly shaped module with 15 second air intake holes 200, and 4 fan-shaped modules 201b, each fan-shaped module 201b having one second air intake hole 200.
[0044] It is important to understand that by modularly designing multiple first fixture modules 201, with at least two first fixture modules 201 having different orthographic projection shapes on the body 10, the first fixture modules 201 can be flexibly combined to adapt to fuel cells of different sizes or shapes, or different sizes and shapes, significantly improving the applicability of the fixture, enhancing its versatility and flexibility, and reducing the cost of replacing fixtures. Simultaneously, the precise positioning and connection of the air intake holes between the body 10 and the first fixture assembly 20, arranged in an array, ensures uniform distribution of adsorption force on the fuel cell surface, effectively reducing fuel cell deformation or displacement caused by localized stress concentration during the cutting process.
[0045] Specifically, by using a standardized main body 10 in conjunction with replaceable and combinable fixture modules, it is possible to avoid customizing fixtures for each size of fuel cell, thus reducing costs. At the same time, the modular design allows for quick replacement of damaged fixture modules without replacing the entire fixture, improving utilization and making maintenance convenient and cost-effective.
[0046] It is also important to understand that the main body 10 and the first fixture assembly 20 are detachably connected for easy cleaning and maintenance, preventing cutting debris from clogging the air passage. The main body 10 and the first fixture assembly 20 use a rigid connection structure (such as locating pins + bolts) to ensure that there is no relative displacement between the fixture modules during high-speed cutting.
[0047] Please see Figure 1 As shown, in some embodiments, the number of second air intake holes 200 on x of the M first fixture modules 201 is different. x can be a positive integer less than or equal to M; for example, x can be 2, 3, 4, 5, etc. Alternatively, the orthographic projection dimensions of the x first fixture modules 201 on the body 10 are the same, or one of their orthographic projection areas is the same, or all three—size, area, and shape—are different, resulting in a different distribution of the number of second air intake holes on the x first fixture modules. It should be understood that by setting at least two first fixture modules 201 with different orthographic projection shapes, the cutting fixture can better fit fuel cells of different shapes to be cut. Fixture modules with different orthographic projection shapes can be flexibly spliced and arranged on the body 10 according to the actual shape and size of the fuel cell. It should be noted that when cutting irregularly shaped fuel cells, fixture modules with corresponding orthographic projection shapes can be selected and combined with different numbers of second suction holes. This maximizes the contact area between the fuel cell and the fixture module during adsorption, further enhancing the stability and firmness of adsorption, effectively preventing the fuel cell from shifting or shaking during cutting, and improving cutting accuracy and product quality. Furthermore, the different shapes of the first fixture modules 201 avoid space waste caused by a single shape of fixture module, improving the space utilization rate of the cutting fixture.
[0048] Please continue reading. Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the orthographic projection areas of y of the M first fixture modules 201 on the body 10 are different. y can be a positive integer less than or equal to M, for example, y can take values of 2, 3, 4, 5, etc. For example, two first fixture modules 201 may have the same orthographic projection shape on the body 10, but different sizes; or both shapes and sizes may be different. It should be understood that by setting at least two first fixture modules 201 to have different orthographic projection areas on the body 10, suitable fixture modules can be flexibly selected and combined according to the size of the fuel cell to be cut. For smaller fuel cells, fixture modules with smaller orthographic projection areas can be used to accurately adsorb the workpiece, avoiding dispersion of adsorption force due to excessively large fixture module areas; while for larger fuel cells, fixture modules with larger orthographic projection areas or combinations of multiple fixture modules can be selected to ensure that the workpiece receives uniform and sufficient adsorption force during cutting, preventing fuel cell movement and improving cutting stability and accuracy. Reasonably combining fixture modules with different orthographic projection areas can optimize the distribution of adsorption force according to the shape and mass distribution of the fuel cell.
[0049] Meanwhile, the first fixture module 201 with different projected areas includes a first fixture module 201 with a larger projected area and a first fixture module 201 with a smaller projected area. Through the above solution, the total number of fixture modules can be reduced, while meeting the fixing requirements for fuel cells of different sizes.
[0050] In some embodiments, the distance between two adjacent third air intakes 300 is equal to the distance between two adjacent second air intakes 200. For example, the distance is the same in the horizontal or vertical direction, where the horizontal direction can be understood as... Figure 2 The horizontal direction, and the vertical direction can be understood as... Figure 2 The vertical direction.
[0051] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, based on the different orthographic projection areas of the first fixture module 201 on the body 10, the number of second suction holes 200 on two or more first fixture modules 201 can be different. It should be understood that by setting at least the number of first suction holes 100 covered by the orthographic projection of the first fixture module 201 on the body 10 to be different, and in conjunction with the different number of second suction holes 200 on at least two first fixture modules 201, the magnitude and distribution of the adsorption force can be flexibly adjusted for fuel cells of different weights and sizes to be cut. For heavier fuel cells or those with more difficult surface adsorption, a fixture module covering more first suction holes 100 can be selected to provide greater adsorption force; while for lighter fuel cells or those easily adsorbed, a fixture module covering fewer first suction holes 100 can be used to avoid over-adsorption and damage to the fuel cell, achieving precise adsorption control and improving cutting stability and processing quality.
[0052] In some embodiments, the orthographic projection shape of the first fixture module 201 on the body 10 includes any one of irregular shape, sector shape, and polygon shape. By setting different orthographic projections of the first fixture module 201 on the body, the first fixture assembly 20 has more combinability, thereby enabling the adsorption of workpieces of different shapes and increasing more possibilities.
[0053] Please see Figure 2 and Figure 5 As shown, in some embodiments, the cutting fixture further includes a second fixture assembly 30, which is supported on the body 10 and has a plurality of third suction holes 300 arranged in an array. At least one third suction hole 300 corresponds to and is interconnected with the first suction hole 100. The second fixture assembly 30 is disposed around the outside of the first fixture assembly 20. There is a gap between the second fixture assembly 30 and the first fixture assembly 20 to form a cutting path 40. It should be understood that the second fixture assembly 30 is disposed around the outside of the first fixture assembly 20 and forms the cutting path 40, which can clearly define the cutting range. During the cutting process, the fuel cell is fixed on the first fixture assembly 20 and the second fixture assembly 30, and the cutting tool operates along the cutting path 40, which can effectively prevent the cutting from deviating from the predetermined trajectory, improve the cutting accuracy and precision, and ensure that the processed workpiece dimensions meet the requirements. The presence of the cutting path 40 can, to a certain extent, block the splashing of debris generated during the cutting process, reducing the impact on surrounding equipment and operators. Meanwhile, the second fixture assembly 30 can improve the stability of the fuel cell during the cutting process, prevent the fuel cell from shifting due to external forces during the cutting process, and ensure the smooth cutting and processing quality.
[0054] Please see Figure 2 , Figure 5As shown, the second fixture assembly 30 is supported on the body 10 and has a plurality of third air intake holes 300 arranged in an array. Each third air intake hole 300 corresponds to and is connected to a first air intake hole 100. The second fixture assembly 30 includes a plurality of second fixture modules 301 that are assembled together. The third air intake holes 300 are disposed on the second fixture modules 301, and at least two second fixture modules 301 have different numbers of third air intake holes 300. It should be understood that the second fixture assembly 30 and the first fixture assembly 20 adopt the same modular design. The second fixture modules 301 with different numbers of third air intake holes 300 can be flexibly combined to adapt to fuel cells of different sizes and shapes to be cut, significantly improving the applicability of the fixture, increasing the versatility and flexibility of the fixture, and reducing the cost of replacing the fixture.
[0055] Meanwhile, the main body 10 and the second fixture assembly 30 are precisely positioned and connected through the air intake holes, and are arranged in an array. By utilizing the different adsorption forces of the second fixture module 301 and their combination, the fixation of the fuel cell edge and outer part is further enhanced, effectively preventing the fuel cell from shifting or shaking during the cutting process, and greatly improving the cutting stability and processing accuracy.
[0056] Specifically, by using a standardized main body 10 in conjunction with replaceable and combinable fixture modules, it is possible to avoid customizing fixtures for each size of fuel cell, thus reducing costs. At the same time, the modular design allows for quick replacement of damaged fixture modules without replacing the entire fixture, improving utilization and making maintenance convenient and cost-effective.
[0057] Please see Figure 6 As shown, in some embodiments, multiple first jig modules 201 are combined to form a first jig assembly 20 whose orthographic projection on the body 10 is rectangular. Four fan-shaped modules 201b are located at the vertices of the first jig assembly 20, each fan-shaped module 201b having a first arc surface 203. The first arc surface 203 is perpendicular to the top surface of the body 10 and protrudes towards the second jig assembly 30. The four first jig modules 201 have planes 202 perpendicular to the top surface of the body 10. The four first arc surfaces 203 and four planes 202 are then connected in a single sequence to form the sidewall of the first jig assembly 20, which is then U-shaped. When cutting the fuel cell, the cutting is performed along the contact edge between the sidewall of the first jig assembly 20 and the fuel cell, resulting in a smooth edge for the cut fuel cell, reducing stress, and improving the cutting yield.
[0058] In another embodiment of this application, the cutting fixture further includes four guide blocks 50, which are disposed on the side of the second fixture assembly 30 facing the first fixture assembly 20, such as... Figure 5As shown, guide blocks 50 are positioned at the intersections of two adjacent, staggered second fixture assemblies 30 and are fitted to fit the second fixture assemblies 30. Four second fixture assemblies form four intersections, with a guide block 50 at each intersection. Each guide block 50 has a second arc surface 501 on its side facing the first arc surface 203, protruding away from the first fixture assembly 20. The four second arc surfaces 501 and the four planar sidewalls of the second fixture assembly 30 facing the first fixture assembly 20 form the sidewalls of the second fixture assembly 30 facing the first fixture assembly 20, which are U-shaped. When cutting the fuel cell, the cutting is performed along the contact edge between the sidewalls of the second fixture assembly 30 and the fuel cell, resulting in smooth edges on the cut fuel cell, reduced stress, and improved yield.
[0059] In practical applications, to reduce stress on both sides of the cutting channel 40, guide blocks 50 and sector modules 201b can be set simultaneously, with guide blocks 50 and sector modules 201b arranged in a one-to-one correspondence. The spacing between guide blocks 50 and sector modules 201b, and the spacing between the first fixture module 201 and the second fixture module 301 with plane 202, combine to form the cutting channel 40.
[0060] Furthermore, in order to keep the width of the cutting channel 40 consistent, the second arc surface 501 is set parallel to the first arc surface 203.
[0061] By cooperating with the first arc surface 203 of the first fixture assembly 20 and the second arc surface 501 of the guide block 50, a precise guide path can be provided for the cutting tool, making the reversal of the cutting tool smoother, effectively avoiding cutting deviation, improving the precision and accuracy of cutting, and also making the edges of the cut fuel cell dimensions smooth, reducing stress, and improving the cutting yield.
[0062] Furthermore, to ensure the width of the cutting path 40 is uniform, the first arc surface 203 and the second arc surface 501 can be made parallel. That is, the center of the circle corresponding to the first arc surface 203 and the center of the circle corresponding to the second arc surface 501 are the same center.
[0063] Furthermore, the corresponding arrangement of the guide block 50 and the first fixture assembly 20 not only serves a guiding function but also enhances the overall structural stability of the fixture to a certain extent. During cutting, the external force generated by the cutting tool is transmitted to the second fixture assembly 30 and the body 10 through the guide block 50, evenly distributing the force and reducing the risk of deformation of the first fixture assembly 20 and other components, thus ensuring the stability and reliability of the fixture during long-term use.
[0064] Please see Figure 4 , Figure 7As shown, in some embodiments, a magnetic adsorption layer 101 is provided on the contact sidewall between the body 10 and the first fixture module 201. The first fixture module 201 is made of magnetic material, and the body 10 and the first fixture module 201 are magnetically connected. It should be understood that the magnetic connection between the body 10 and the first fixture module 201 makes the installation and removal of the first fixture module 201 extremely simple and quick. Operators do not need to use complex tools; they only need to bring the first fixture module 201 close to the magnetic adsorption layer 101 on the body 10 for automatic adsorption and fixation. During removal, only a certain external force needs to be applied to overcome the magnetic force to easily remove the module. This greatly saves time in changing fixture modules, improves production efficiency, and is especially suitable for scenarios where fixture modules need to be frequently changed to adapt to different workpiece processing. The magnetic adsorption layer 101 can provide a relatively uniform adsorption force, enabling the fixture module to be accurately positioned on the body 10, ensuring accurate relative positions between modules and between the module and the body 10. During the cutting process, the stable magnetic connection effectively prevents the fixture module from loosening or shifting, ensuring the structural stability and machining accuracy of the cutting fixture. Even under high-speed cutting or impact from external forces, the magnetic connection can maintain the module's fixation, reducing cutting errors caused by module loosening.
[0065] Furthermore, compared to traditional mechanical connection methods (such as bolted connections), magnetic connections reduce the need for replacement due to wear, loss, or damage of connecting parts (such as bolts and nuts), thus lowering maintenance costs and workload. Simultaneously, because module replacement is convenient, when a fixture module malfunctions or wears out, it can be quickly replaced, improving production efficiency and reducing replacement costs.
[0066] Please see Figure 1 , Figure 2 , Figure 4 As shown, in some embodiments, the body 10 has a first chamber 102 and an air extraction port 103 connected together, and a first suction hole 100 connected to the first chamber 102. It should be understood that the interconnected design of the first chamber 102, air extraction port 103, and first suction hole 100 in the body 10 constitutes a complete and efficient suction system. By connecting an external suction device through the air extraction port 103, air can be quickly extracted from the first chamber 102, creating a negative pressure within the first chamber 102. This negative pressure, in turn, allows the workpiece to be firmly adsorbed onto the surface of the first fixture assembly 20 opposite to the body 10 through the first suction hole 100. This design ensures the stability and continuity of suction, ensuring that the workpiece remains adsorbed during the cutting process, effectively preventing the workpiece from moving due to insufficient adsorption force, and improving the cutting accuracy and quality.
[0067] Please see Figure 2 and Figure 3As shown, in some embodiments, the cutting fixture further includes a storage box 60, which is disposed on the side of the main body 10 opposite to the first fixture assembly 20 and connected to the main body 10. The storage box 60 has a second chamber 601. It should be understood that the storage box 60, disposed on the side of the main body 10 opposite to the first fixture assembly 20, makes reasonable use of the fixture's space, making the overall structure of the fixture more compact and orderly. This layout does not affect the normal operation of the first fixture assembly 20 and the second fixture assembly 30, while providing a convenient storage area for operators, improving the practicality and ease of operation of the fixture. When the cutting fixture needs to be moved or stored, the storage box 60 can provide space to accommodate the first fixture module 201 and the second fixture module 301, preventing them from scattering or being lost during handling. Simultaneously, the storage box 60 is connected to the main body 10 as a whole, making the fixture more organized during handling and storage, saving space, and facilitating management and storage.
[0068] In some embodiments, the body 10 has a plurality of optical positioning marks (not shown) on the side surface facing the first fixture assembly 20. It should be understood that by dividing the surface of the body 10 into a plurality of 1cm*1cm regions, and by setting screen printing ink in these regions as CCD (Charge Coupled Device) optical positioning marks, a richer set of CCD optical positioning marks can meet the precise positioning requirements under different designs, thereby improving the cutting accuracy of solid oxide fuel cells.
[0069] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
