[0037] As shown in Figures 1 to 8 The electric pile packaging device disclosed by the embodiment of the present application comprises a pressing assembly 10, a spraying assembly 20 and a liquid supply assembly. The pressing assembly 10 comprises a first pressing structure 11 and a second pressing structure 12, and the electric pile to be packaged is arranged between the first pressing structure 11 and the second pressing structure 12. The spraying assembly 20 is connected with the pressing assembly 10, and is arranged towards the electric pile to be packaged. The liquid supply assembly is connected with the spraying assembly 20 in communication, and contains deionized water.

[0038] The technical scheme of the embodiment one is applied, the plurality of battery pieces are compressed under the joint action of the first compression structure 11 and the second compression structure 12, the plurality of battery pieces are bundled by the binding belt, in the process, the friction between the binding belt and the battery pieces increases the internal stress of the battery pieces, the spraying assembly 20 sprays ionized water on the battery pieces, on the one hand, the friction between the binding belt and the battery pieces is reduced by spraying liquid, on the other hand, the static electricity generated by the friction is neutralized, and the generation of the internal stress of the battery pieces is reduced from the above two aspects. The technical scheme of the embodiment one effectively solves the problem that the gas leakage caused by the large internal stress of the battery pieces exists in the fuel cell stack packaging process in the prior art.

[0039] As shown in Figures 1 to 8 In the technical scheme of the embodiment one, the first compression structure 11 has the first liquid supply pipeline 111, the second compression structure 12 has the second liquid supply pipeline 121, the spraying assembly 20 includes the first spraying structure 21 and the second spraying structure 22, the first spraying structure 21 is in communication with the first liquid supply pipeline 111, and the second spraying structure 22 is in communication with the second liquid supply pipeline 121. The first liquid supply pipeline 111 is arranged in the first compression structure 11, the second liquid supply pipeline 121 is arranged in the second compression structure 12, when the first compression structure 11 moves, the first liquid supply pipeline 111 and the first spraying structure 21 move together with the first compression structure 11, when the stacks of different sizes are packaged, the position of the first spraying structure 21 does not need to be adjusted separately, the operation is more convenient, and the first liquid supply pipeline 111 is arranged in the first compression structure 11 and the second liquid supply pipeline 121 is arranged in the second compression structure 12, without separately arranging the liquid pipeline, the cost and the floor area of the whole equipment are reduced.

[0040] As shown in Figures 1 to 8As shown, in the technical scheme of the embodiment one, the first liquid supply pipeline 111 comprises a first liquid inlet 1111, a first liquid outlet 1112 and a second liquid outlet 1113, the first liquid inlet 1111 is in communication with the liquid supply assembly, the first spraying structure 21 comprises a first spraying part 211 and a second spraying part 212, a first end of the first spraying part 211 is in communication with the first liquid outlet 1112, a second end of the first spraying part 211 is arranged towards the first end face of the to-be-packaged stack, a first end of the second spraying part 212 is in communication with the second liquid outlet 1113, and a second end of the second spraying part 212 is arranged towards the side face of the to-be-packaged stack. The liquid supply assembly passes deionized water from the first liquid inlet 1111 into the first liquid supply pipeline 111, the deionized water flows through the first liquid supply pipeline 111 and flows to the first spraying part 211 and the second spraying part 212 from the first liquid outlet 1112 and the second liquid outlet 1113 respectively, and is sprayed to the end face and the side face of the to-be-packaged stack respectively. Before the binding band is bound, the air tightness of the battery piece needs to be detected first, there are three kinds of media and corresponding medium cavities in the stack, nitrogen is passed in for air tightness detection, if the air tightness is not good, the stack has a gas outlet outside, the second spraying part 212 is used to spray deionized water to the side face of the stack to observe the bubble position, so that the leakage point can be quickly judged, and the test efficiency is high; after the test is completed, the stack is bound by the binding band, the binding band mainly rubs against the end face of the stack, at this time, the first spraying part 211 is used to spray deionized water to the end face of the stack, so that the internal stress generated in the stack can be effectively reduced. The arrangement of the first spraying part 211 and the second spraying part 212 can not only accurately and quickly test the leakage point position of the stack, but also reduce the internal stress generated in the stack due to friction after the test is completed, so that the problem of poor air tightness of the battery caused by the internal stress after the test is avoided.

[0041] As Figures 1 to 8As shown, in the technical solution of Embodiment 1, the second liquid supply pipeline 121 includes a second liquid inlet 1211, a third liquid outlet 1212 and a fourth liquid outlet 1213. The second liquid inlet 1211 is connected to the liquid supply assembly. The second spray structure 22 includes a third spray section 221 and a fourth spray section 222. The first end of the third spray section 221 is connected to the third liquid outlet 1212, and the second end of the third spray section 221 is disposed facing the second end face of the battery stack to be packaged. The second end of the fourth spray section 222 is connected to the fourth liquid outlet 1213, and the second end of the fourth spray section 222 is disposed facing the side of the battery stack to be packaged. The liquid supply assembly introduces deionized water into the second liquid supply pipe 121 through the second inlet 1211. The deionized water flows through the second liquid supply pipe 121 and exits through the third outlet 1212 and the fourth outlet 1213 to the third spray section 221 and the fourth spray section 222, respectively, and is sprayed onto the end face and side face of the fuel cell stack to be packaged. The second liquid supply pipe 121 and the second spray structure 22 are located below the fuel cell stack, while the first liquid supply pipe 111 and the first spray structure 21 are located above the fuel cell stack. The first spray structure 21 and the second spray structure 22 spray simultaneously from above and below the fuel cell stack, improving the efficiency of fuel cell stack leak detection and reducing the generation of internal stress within the fuel cell stack.

[0042] like Figures 1 to 8 As shown, in the technical solution of Embodiment 1, the first clamping structure 11 has a plurality of first receiving grooves 112, and the second clamping structure 12 has a plurality of second receiving grooves 122. The plurality of first receiving grooves 112 and the plurality of second receiving grooves 122 are arranged in a one-to-one correspondence. The opening of the first receiving grooves 112 and the second receiving grooves 122 provides a reserved position for the binding of the straps. The straps extend into the first receiving grooves 112 and the second receiving grooves 122 to bind the fuel cell stack. The first clamping structure 11 and the second clamping structure 12 are respectively arranged corresponding to the upper and lower end faces of the fuel cell stack. Friction is generated between the straps extending into the first receiving grooves 112 and the second receiving grooves 122 and the two end faces of the fuel cell stack. Therefore, the first spray part 211 and the second spray part 212 are respectively arranged toward the upper end face and the lower end face of the fuel cell stack, reducing the coefficient of friction at both points, providing lubrication, reducing the generation of frictional force, and thus reducing the generation of internal stress in the fuel cell stack.

[0043] like Figures 1 to 8As shown in the technical scheme of Embodiment One, the first liquid outlet 1112 is arranged on the inner wall of the first accommodating groove 112, the first spraying part 211 is arranged in the first accommodating groove 112, the third liquid outlet 1212 is arranged on the inner wall of the second accommodating groove 122, and the third spraying part 221 is arranged in the second accommodating groove 122. The first spraying part 211 is arranged inside the first accommodating groove 112, and the height of the first spraying part 211 is less than the depth of the first accommodating groove 112; the third spraying part 221 is arranged in the second accommodating groove 122, and the height of the third spraying part 221 is less than the depth of the second accommodating groove 122. The above structure leaves space for the strap to extend, avoiding the strap from contacting the first spraying part 211 or the third spraying part 221, and the problem of the strap being hindered from extending by the two.

[0044] As shown in the technical scheme of Embodiment One, Figures 1 to 8 As shown in the technical scheme of Embodiment One, the first liquid supply pipeline 111 has a first branch, a second branch and a third branch, the first branch is provided with a first valve, the second branch is provided with a second valve, the third branch is provided with a third valve, the first liquid outlet 1112 is arranged on the first branch, the second liquid outlet 1113 includes a plurality of second liquid outlets 1113, and the plurality of second liquid outlets 1113 are arranged on the second branch and the third branch respectively. The second liquid supply pipeline 121 has a fourth branch, a fifth branch and a sixth branch, the fourth branch is provided with a fourth valve, the fifth branch is provided with a fifth valve, the sixth branch is provided with a sixth valve, the third liquid outlet 1212 is arranged on the fourth branch, and the fourth liquid outlet 1213 includes a plurality of fourth liquid outlets 1213, and the plurality of fourth liquid outlets 1213 are arranged on the fifth branch and the sixth branch respectively. The second branch and the fifth branch are arranged corresponding to the front face of the stack, and the third branch and the sixth branch are arranged corresponding to the rear side of the stack, so as to ensure that the leak point inspection of the stack is complete. The first branch, the second branch, the third branch, the fourth branch, the fifth branch and the sixth branch are respectively provided with the first valve, the second valve, the third valve, the fourth valve, the fifth valve and the sixth valve. By cooperatively controlling the above valves, the deionized water can be controlled to enter different branches, and then the deionized water can be controlled to be sprayed to the surface of the stack from different positions, so as to meet the use requirement.

[0045] As shown in the technical scheme of Embodiment One, Figures 1 to 8As shown, in the technical solution of Embodiment 1, the clamping assembly 10 further includes a vertical drive structure. The first clamping structure 11 is connected to the output end of the vertical drive structure. The first clamping structure 11 has a clamping state close to the second clamping structure 12 and a waiting-to-be-clamped state away from the second clamping structure 12. During use, the battery cells to be encapsulated are first placed on the second clamping structure 12. The vertical drive structure controls the first clamping structure 11 to press down, pressing multiple battery cells tightly together. The battery stack has three media and corresponding media cavities. Nitrogen gas is introduced into each medium for airtightness testing. If the airtightness of the battery is poor, the second spray section 212 and the fourth spray section 222 are activated to spray the sides of the battery stack to detect specific leaks. If the airtightness of the battery is good, the second spray section 212 and the fourth spray section 222 do not need to be activated. After the inspection is completed, the battery cells are bound with straps, and the first spray section 211 and the third spray section 221 are activated to spray the end face of the battery stack to reduce the generation of internal stress.

[0046] like Figure 9 As shown, the technical solution of Embodiment 2 differs from that of Embodiment 1 in that there are three first liquid inlets 1111 and three second liquid inlets 1211, and three first liquid supply pipes 111 and three second liquid supply pipes 121 are also provided. The three first liquid inlets 1111 are connected to the three first liquid supply pipes 111 and are arranged in a one-to-one correspondence. The three second liquid inlets 1211 are connected to the three second liquid supply pipes 121 and are arranged in a one-to-one correspondence. Two of the three first liquid supply pipes 111 located on both sides are connected to the second spray section 212, and the one located in the middle is connected to the first spray section 211. Two of the three second liquid supply pipes 121 located on both sides are connected to the fourth spray section 222, and the one located in the middle is connected to the third spray section 221. The first spray section 211 and the second spray section 212 are respectively connected to different first liquid supply lines 111, and the third spray section 221 and the fourth spray section 222 are respectively connected to different second liquid supply lines 121, which reduces the problem of mixing during use and reduces the number of valves, thus reducing costs.

[0047] The difference between the technical solution of Embodiment 3 and that of Embodiment 1 is that the fuel cell stack packaging equipment further includes a drying component, which is positioned facing the fuel cell stack to be packaged. The drying component allows for rapid drying of the bundled fuel cell stack, facilitating subsequent processes.

[0048] In the technical scheme of the embodiment three, the drying assembly comprises a gas supply structure, the first liquid supply pipeline 111 has a first gas inlet, the second liquid supply pipeline 121 has a second gas inlet, and the first gas inlet and the second gas inlet are in communication with the gas supply structure. The gas supply structure supplies clean gas into the first liquid supply pipeline 111 and the second liquid supply pipeline 121, and the clean gas is finally sprayed from the first spraying structure 21 and the second spraying structure 22 to the surface of the stack, so that the stack is quickly dried by blowing the deionized water away from the surface of the stack and accelerating the air flow. In this process, the residual deionized water in the first liquid supply pipeline 111 and the second liquid supply pipeline 121 is blown out, avoiding the problem that the first compression structure 11 and the second compression structure 12 are easily eroded due to the long-term accumulation of deionized water inside them, and improving the service life of the compression assembly. The gas supply structure can use a hot air blower to heat the clean gas to a certain temperature before drying, further improving the drying efficiency and thus providing production efficiency.

[0049] In summary, the application provides a stack packaging equipment. The equipment mainly consists of four parts: an upper tooling (first compression structure 11), a lower tooling (second compression structure 12), a side spraying device (second spraying part 212 and fourth spraying part 222), an end plate spraying device (first spraying part 211 and third spraying part 221), and an electromagnetic valve. The upper tooling cooperates with the upper end plate to transfer the load of the press (vertical driving structure) to the end plate and the stack. The lower tooling cooperates with the lower end plate to constrain the vertical displacement of the stack. The side spraying device is a deionized water flow guide device used for detecting leakage points on the side of the stack. The end plate spraying device is a deionized water flow guide device used for spraying the contact surface between the end plate and the binding belt. The electromagnetic valve controls the flow of medium. The stack is stacked, and the transfer device transfers the stack to the lower tooling of the press. The press is operated to press the stack until the lower pressure of the press reaches the required pressure for stacking. After stacking, air tightness detection is performed. If there is an external leakage, the spray electromagnetic valve is opened to check and identify the leakage point. The binding belt can also be checked on one side. After the air tightness detection is completed and there is no leakage point, the binding belt is prepared for bundling. Before bundling, the end plate is sprayed with deionized water, the end plate electromagnetic valve is opened, and the spraying starts. After spraying is completed, the binding belt is bundled and welded, and the stack is finally offline. The application sprays deionized water on the end plate to solve the problem of slow release of internal stress of the binding belt caused by nonlinear friction between the binding belt and the end plate in stack packaging, accelerate the stress release speed, and improve the production rhythm. The application sprays deionized water on the end plate to solve the problem of poor load stability and durability after stack packaging, improve the load stability and product safety, and improve the leakage identification efficiency, repair speed and quality through the modification of the upper and lower toolings of the packaging.
