[0040] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] like Figure 1-11 As shown, the strap-type fuel cell stack assembly device of the embodiment of the present invention includes: a bracket 1, a support platform 2, a pressing platform 3 and a binding component 5.

[0042] The support 1 includes a base 12 and a frame 11. The base 12 includes a workbench 121. The frame 12 is connected to the workbench 121 and is located above the workbench 121. The support platform 2 is arranged on the upper surface of the workbench 121. The upper surface of the support platform 2 is provided with a strap passing through and extending along a first horizontal direction (such as Figure 1 A plurality of first avoidance grooves 29 extending in the front-to-rear direction of the plurality of first avoidance grooves 29 are provided along the second horizontal direction (such as Figure 1The upper surface of the support platform 2 is used to place the battery stack 6. The pressing platform 3 is located above the support platform 2 and is movably arranged on the frame 12 in the up-down direction. The pressing platform 3 is used to press the battery stack 6. The lower surface of the pressing platform 3 is provided with a plurality of second avoidance grooves 323 extending along the first horizontal direction for the straps to pass through. The plurality of second avoidance grooves 323 are arranged at intervals along the second horizontal direction. The plurality of first avoidance grooves 29 correspond to the plurality of second avoidance grooves 323 in the up-down direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0043] Specifically, Figure 1-Figure 3 As shown, the bottom of the base 12 is also provided with a leg 13, and there are multiple legs 13, and the multiple legs 13 are arranged at intervals along the circumference of the base 12 to ensure that the base 12 can be placed stably. The support platform 2 includes a first side surface 21 and a second side surface 22 opposite to each other in the first horizontal direction, and the first avoidance groove 29 runs through the first side surface 21 and the second side surface 22. That is, the front side surface of the support platform 2 is the first side surface 21, and the rear side surface of the support platform 2 is the second side surface 22. The extension direction of the first avoidance groove 29 is consistent with the front-to-back direction. The first avoidance groove 29 runs through the first side surface 21 and the second side surface 22 to facilitate the strap to pass through the first avoidance groove 29. The support platform 2 is provided with multiple first avoidance grooves 29 to achieve the placement of multiple straps. The pressing platform 3 includes a third side surface and a fourth side surface opposite to each other in the first horizontal direction, and the second avoidance groove runs through the third side surface and the fourth side surface.

[0044] The binding assembly 5 is movably arranged along the second horizontal direction, and is used to pass the binding strap through the first avoidance groove 29 and the second avoidance groove 323 and bind it to the battery stack 6. It can be understood that multiple binding straps can be used to bind a battery stack 6. After the binding assembly 5 binds one binding strap to the battery stack 6, it moves in the left and right direction and binds other binding straps to the battery stack 6, so as to improve the stability of the binding of the battery stack 6.

[0045] The fuel cell stack 6 assembly device of the embodiment of the present invention further includes a first driver 100, which includes a first body 1001 and a first telescopic rod 1002. The first body 1001 is disposed on the frame 11, and the first telescopic rod 1002 is movable in the up and down directions relative to the first body 1001. The first telescopic rod 1002 is connected to the pressing platform 3. Figure 1 and Figure 2As shown, there are two first drivers 100, and the two first drivers 100 are arranged opposite to each other in the left-right direction, so that the force exerted by the first telescopic rod 1002 of the first driver 100 on the pressing platform 3 is more balanced, which is conducive to the up and down movement of the pressing platform 3. It should be noted that the first driver 100 can be a driving member with a telescopic structure such as an electric cylinder or a cylinder, so as to drive the pressing platform 3 to move in the up and down direction. The strap-type fuel cell stack assembly device of the embodiment of the present invention can use the pressing platform to compress the stack, so that the binding component can directly bind the strap to the stack.

[0046] In addition, a plurality of first avoidance grooves are arranged at intervals along the second horizontal direction, and a plurality of second avoidance grooves are arranged at intervals along the second horizontal direction. When the size of the battery stack changes in the second horizontal direction, the positions of the first avoidance grooves and the second avoidance grooves also change accordingly.

[0047] Therefore, the strap-type fuel cell stack assembly device of the present invention can move the binding assembly along the second horizontal direction, so that the straps corresponding to different first avoidance grooves and second avoidance grooves can be bound on fuel cell stacks of different sizes.

[0048] Therefore, the strap-type fuel cell stack assembly device of the embodiment of the present invention can assemble fuel cell stacks of different sizes, and has the advantage of good applicability.

[0049] In some embodiments, Figure 4 As shown, the upper surface of the support platform 2 is provided with a first protrusion 291 and a second protrusion 292, the first protrusion 291 and the second protrusion 292 are arranged at intervals in the second horizontal direction, the first protrusion 291 and the second protrusion 292 extend along the first horizontal direction, and at least a portion of the first avoidance groove 29 is formed between the first protrusion 291 and the second protrusion 292.

[0050] It can be understood that the upper surface of the support platform 2 is provided with a first protrusion 291 and a second protrusion 292, wherein a first avoidance groove 29 can be formed between the first protrusion 291 and the second protrusion 292, or, as shown in FIG. Figure 3 As shown, a first avoidance groove 29 is formed on the upper surface of the support platform 2 , and a first protruding portion 291 and a second protruding portion 292 are disposed on both sides of the first avoidance groove 29 .

[0051] That is to say, the first avoidance groove 29 is used to avoid the clamp 74 for binding the battery stack 6. When the upper surface of the supporting platform 2 is provided with a first protrusion 291 and a second protrusion 292, the battery stack with the clamp 74 is transported to the supporting platform 2. At this time, the clamp 74 is placed in the first avoidance groove 29 to realize the function of avoiding the clamp 74.

[0052] Alternatively, when the first avoidance groove 29 is provided on the upper surface of the support platform 2, and the first protrusion 291 and the second protrusion 292 are provided on the upper surface of the support platform 2, the distance between the first protrusion 291 and the second protrusion 292 is greater than the width of the first avoidance groove 29, so as to avoid the clamps 74 of different widths. Of course, when placing straps of different widths on the support platform 2, that is, when the straps are wider, the straps can be placed between the first protrusion 291 and the second protrusion 292; when the straps are narrower, the straps can be placed in the first avoidance groove 29.

[0053] In some embodiments, Figure 7-Figure 11 As shown, the strap-type fuel cell stack assembly device of the embodiment of the present invention also includes a binding component 5, which is movably arranged along the second horizontal direction. The binding component 5 is used to pass the strap through the first avoidance groove 29 and the second avoidance groove 323 and bind it to the stack 6.

[0054] It is understandable that multiple straps can be used to bundle a battery stack 6. After the bundling component 5 bundles one strap on the battery stack 6, it moves in the left and right direction to bundle other straps on the battery stack 6, so as to improve the stability of the bundling of the battery stack 6.

[0055] like Figure 7-Figure 11 As shown, the binding assembly 5 includes: a first pressing member 501, a first bending member 502, a second bending member 503, a first clamping member 504, a second clamping member 505, a second pressing member 506, a third pressing member 507, a third bending member 508, a fourth bending member 509 and a fourth pressing member 510 and a welding member 511.

[0056] The first pressing member 501 is movably disposed in the base 12 along the vertical direction and the second horizontal direction so as to press the binding band to the lower surface of the battery stack 6. Figure 7 As shown, the first clamping member 501 includes a first horizontal driving part 5012 and a first vertical driving part 5013. The first vertical driving part 5013 is movably arranged on the first horizontal driving part 5012 along the left and right directions. The first clamping member 501 includes a first clamping block 5011. The first vertical driving part 5013 can drive the first clamping block 5011 to move along the up and down directions so as to press the strap to the lower surface of the battery stack 6.

[0057] The first bending member 502 and the second bending member 503 are arranged at intervals in the first horizontal direction, and the first bending member 502 and the second bending member 503 are movably arranged in the base 12 along the up-down direction and the second horizontal direction, so as to bend the two ends of the strap in the first horizontal direction upward. Figure 8As shown, a second horizontal driving unit 5023 is also provided on the base 12, and the first bending member 502 and the second bending member 503 are both provided on the second horizontal driving unit 5023. The second horizontal driving unit 5023 can drive the first bending member 502 and the second bending member 503 to move simultaneously in the left and right directions. The first bending member 502 includes a first bending block 5021, and the second bending member 503 includes a second bending block 5031. A second vertical driving unit 5024 is provided on at least one of the first bending member 502 and the second bending member 503. The second vertical driving unit 5024 can drive the first bending block 5021 and the second bending block 5031 to move simultaneously in the up and down directions so as to bend the two ends of the strap upward at the front and back.

In other words, the distance between the first bending member 502 and the second bending member 503 in the front-back direction can be adjusted to be suitable for bending straps of different thicknesses. Among them, the first bending member 502 and the second bending member 503 can be moved manually, for example, a slide rail is arranged on the moving plate 5022, and a slideway matching the slide rail is arranged at the bottom of the first bending member 502 and the second bending member 503. When the first bending member 502 and the second bending member 503 are moved to an appropriate position, they can be fixed by means of clamping or the like to achieve bending straps of different thicknesses. Alternatively, the first bending member 502 and the second bending member 503 may be moved automatically, for example, the first bending member 502 and the second bending member 503 may be driven by an electric cylinder or a pneumatic cylinder.

[0059] The first clamping member 504 and the second clamping member 505 are arranged at intervals in the first horizontal direction. The first clamping member 504 is used to clamp one end of the strap in the first horizontal direction, and the second clamping member 505 is used to clamp the other end of the strap in the first horizontal direction. The first clamping member 504 and the second clamping member 505 are movably arranged on the frame 11 along the up-down direction and the second horizontal direction to tighten the strap.

The fourth clamping block 5101 can simultaneously press the two ends of the strap, or, as shown in FIG. Fig.11 As shown, there are two fourth pressing blocks 5101, one of which can press one end of the binding belt, and the other can press the other end of the binding belt.

[0064] The welding member 511 is movably arranged on the frame 11 in the up-down direction and the second horizontal direction so as to weld the two ends of the bandage. Specifically, the pressing platform 3 is provided with a tenth horizontal driving part, the welding member 511 is arranged on the tenth horizontal driving part, the tenth horizontal driving part can drive the welding member 511 to move in the left-right direction, the welding member 511 includes a welding part 5111, and the welding member 511 is provided with a fifth vertical driving part, the fifth vertical driving part can drive the welding part 5111 to move in the up-down direction so as to weld the two ends of the bandage.

[0065] It should be noted that the above-mentioned driving parts can be electric cylinders or pneumatic cylinders, and can also be linear modules.

[0066] In some embodiments, Figure 6 As shown, the pressing platform 3 includes a base plate 31 and a pressing head 32. The pressing head 32 is arranged below the base plate 31. The base plate 31 is movably arranged on the frame 11 along the up and down directions. The second avoidance groove 323 is arranged on the lower surface of the pressing head 32. The size of the pressing head 32 in the first horizontal direction is smaller than the size of the base plate 31. The pressing head 32 is located in the middle position of the base plate 31 in the first horizontal direction.

[0067] Specifically, Figure 1-Figure 3 As shown, the substrate 31 is connected to the telescopic rod of the first driver 100 so that the first driver 100 can drive the substrate 31 to move in the up and down directions. The size of the pressure head 32 in the first horizontal direction is smaller than that of the substrate 31, which is beneficial to provide avoidance space for other components.

[0068] In some embodiments, the second clamping member 506 and the third clamping member 507 are movably disposed on the substrate 31 along the first horizontal direction and the second horizontal direction, and the second clamping member 506 and the third clamping member 507 are both located below the pressure head 32, the third bending member 508 and the fourth bending member 509 are movably disposed on the substrate 31 along the first horizontal direction and the second horizontal direction, the third bending member 508 and the fourth bending member 509 can extend into the second avoidance groove 323, and the fourth clamping member 510 is movably disposed on the pressure head 32 along the up and down directions and the second horizontal direction.

[0069] It can be understood that the fifth horizontal driving part 5062 is arranged on the substrate 31, and the second clamping member 506 and the third clamping member 507 are both located below the pressure head 32, so that the two ends of the strap can be pressed against the front and rear sides of the battery stack 6 by the second clamping member 506 and the third clamping member 507, respectively, to facilitate the third bending member 508 and the fourth bending member 509 to bend the two ends of the strap.

[0070] In some embodiments, Figure 3As shown, a first through hole 1211 is provided on the upper surface of the workbench 121, and a second through hole 201, a third through hole 202 and a fourth through hole 203 are provided on the upper surface of the support platform 2 which are connected to the first through hole 1211. Each of the second through hole 201, the third through hole 202 and the fourth through hole 203 passes through the bottom wall surface of the first avoidance groove 29, the third through hole 202 and the fourth through hole 203 are arranged at intervals in the first horizontal direction, and the second through hole 201 is located between the third through hole 202 and the fourth through hole 203. The first clamping member 501 can pass through the first through hole 1211 and the second through hole 201, the first bending member 502 can pass through the first through hole 1211 and the third through hole 202, and the second bending member 503 can pass through the first through hole 1211 and the fourth through hole 203.

[0071] It can be understood that the second through hole is connected to the first through hole 1211, so that the first pressing member 501 can pass through the first through hole 1211 and the second through hole 201, wherein the second through hole 201 can be one, that is, the plurality of first avoidance grooves 29 are connected to the second through hole 201, or the second communicating hole is multiple, such as Figure 2 and Figure 3 As shown, the plurality of second through holes 202 and the plurality of first avoidance grooves 29 correspond one to one. Similarly, the number of the third through hole 202 and the number of the fourth through hole 203 may also be one or more.

[0072] In some embodiments, Figure 6 As shown, the substrate 31 is provided with a fifth through hole 311 and a sixth through hole 312, and the fifth through hole 311 and the sixth through hole 312 are arranged at intervals in the first horizontal direction, the pressure head 32 is located between the fifth through hole 311 and the sixth through hole 312, the first clamping member 504 can pass through the fifth through hole 311, and the second clamping member 505 can pass through the sixth through hole 312.

[0073] It is understandable that the fifth through hole 311 and the sixth through hole 312 may be one, and the plurality of second avoidance grooves 323 are all connected to the fifth through hole 311 and the sixth through hole 312, so that the first clamping member 504 passes through the fifth through hole 311 and the second clamping member 505 passes through the sixth through hole 312, thereby achieving the function of tensioning the strap. Figure 8 As shown, there may be a plurality of fifth through holes 311 and a plurality of sixth through holes 312 , and the plurality of fifth through holes 311 correspond to the plurality of second avoidance grooves 323 one by one, and the plurality of sixth through holes 312 correspond to the plurality of second avoidance grooves 323 one by one.

[0074] In some embodiments, Figure 6As shown, the pressure head 32 includes a cavity 321 that passes through from top to bottom, the second avoidance groove 323 is connected to the cavity 321, and the fourth clamping member 510 is movably arranged on the inner wall of the cavity 321 along the up and down directions and the second horizontal direction, and the fourth clamping member 510 can pass through the second avoidance groove 323.

[0075] It can be understood that the ninth horizontal driving part 5102 is arranged on the inner wall of the cavity 321, and the length distance of the cavity 321 in the left and right direction is greater than the distance of the battery stack 6 in the left and right direction, so that when the ninth horizontal driving part 5102 drives the fourth clamping member 510 to clamp the two ends of the strap, the fourth clamping member 510 can clamp multiple straps on the battery stack 6 in sequence.

[0076] In some embodiments, Figure 6 As shown, the substrate 31 is provided with a seventh through hole 322 , which is located between the fifth through hole 311 and the sixth through hole 312 and communicates with the cavity 321 , and the welding piece 511 can pass through the seventh through hole 322 and the cavity 321 .

[0077] It is understandable that if Figure 6 As shown, the seventh through hole 322 is connected to the cavity 321 to form a through hole that passes through the pressing platform 3 in the up and down directions. When the fourth clamping member 510 clamps the two ends of the strap, the welding member 511 can weld the clamped strap through the seventh through hole 322 and the cavity 321.

[0078] It should be noted that the support platform is a replaceable tooling, that is, when the width, spacing and number of the straps are adjusted, or when the size of the battery stack, the size, shape and position of the air inlet and outlet cavities are adjusted, the support platform can be replaced to match straps or battery stacks of different specifications. Similarly, the downward pressure platform is also a replaceable tooling.
