[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fuel cell stack production line, which is conducive to improving the high-precision assembly of the fluid flow frame and the partition plate, and at the same time, its mechanism layout is reasonable, which is conducive to improving efficiency and saving the installation space of the factory.

[0004] The embodiments of this utility model are achieved through the following technical solutions: An electrode stack production line includes a pre-assembly module, a flipping module, a first adhesive application module, and an assembly module arranged sequentially along a first direction. The pre-assembly module is used to assemble a flow frame and a separator to form an electrode body. The flipping module is used to flip the electrode body. The first adhesive application module is used to apply adhesive to the other side of the flow frame. The assembly module is used to assemble the electrode body, carbon felt, separator, bipolar plate, and sealing gasket to form an electrode stack. The pre-assembly module includes a first frame, on which a material preparation area and an assembly area are arranged sequentially along a second direction. The material preparation area includes a first storage area for placing the flow frame, a second storage area for placing the separator, and a first assembly area, arranged sequentially along the second direction. The assembly area is equipped with a second shaping module. The assembly area has a loading station and an assembly station arranged sequentially along a first direction. The second shaping module can reciprocate between the loading station and the assembly station. A first transfer mechanism, a second transfer mechanism, and a third transfer mechanism are configured on the first frame. The first transfer mechanism is used to transfer the liquid flow frame from the first storage area to the loading station. The second transfer mechanism is used to transfer the partition from the second storage area to the first shaping module. The third transfer mechanism is used to transfer the partition from the first shaping module to the assembly station. The first direction and the second direction are perpendicular, and both the first direction and the second direction are parallel to the ground. During use, the fluid flow frame and the partition can be shaped and positioned separately before being assembled into the electrode body. Specifically, the partition is positioned twice by the first shaping module, and the fluid flow frame is positioned twice by the second shaping module. Then, the two are assembled at the assembly station, which helps to improve the assembly accuracy and ensure the assembly quality of the electrode body. At the same time, the pre-assembled module has a reasonable structural layout. The secondary positioning and assembly path length of the partition is basically the same as that of the fluid flow frame. The secondary positioning movement path of the partition is perpendicular to the assembly movement path of the partition, and the secondary positioning movement path of the partition is perpendicular to the secondary positioning movement path of the fluid flow frame. The assembly movement path of the partition is perpendicular to the assembly movement path of the fluid flow frame. Based on this, the movement paths of the partition and the fluid flow frame on the first frame form a rectangular structure layout. The travel base plates of the partition and the fluid flow frame from the storage area to the assembly station are consistent, which is conducive to the efficiency matching of the mechanism for transferring the two and saves the assembly space of the mechanism.

[0008] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0009] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0010] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0011] Please refer to Figures 1 to 18 A fuel cell stack production line includes a pre-assembly module 1, a flipping module 2, a first adhesive application module 3, and an assembly module 5 arranged sequentially along a first direction X. The pre-assembly module 1 assembles a flow frame A and a separator B to form an electrode body C. The flipping module 2 flips the electrode body C. The first adhesive application module 3 applies adhesive to the other side of the flow frame A. The assembly module 5 assembles the electrode body C, carbon felt D, a separator, a bipolar plate, and a sealing gasket to form a fuel cell stack. The pre-assembly module 1 includes a first frame 11, on which a material preparation area a and an assembly area b are arranged sequentially along a second direction Y. Within the material preparation area a, a first storage area a1 for placing the flow frame A, a second storage area a2 for placing the separator B, and a first shaping module 12 are arranged sequentially along the second direction Y. Assembly area b is equipped with a second shaping module 16. Assembly area b is provided with a loading station b1 and an assembly station b2 along the first direction X. The second shaping module 16 can reciprocate between the loading station b1 and the assembly station b2. The first frame 11 is equipped with a first transfer mechanism 14, a second transfer mechanism 15 and a third transfer mechanism 17. The first transfer mechanism 14 is used to transfer the liquid flow frame A from the first storage area a1 to the loading station b1. The second transfer mechanism 15 is used to transfer the partition B from the second storage area a2 to the first shaping module 12. The third transfer mechanism 17 is used to transfer the partition B from the first shaping module 12 to the assembly station b2. The first direction X and the second direction Y are perpendicular and both the first direction X and the second direction Y are parallel to the ground.

[0012] With this configuration, the fluid flow frame A and the partition B can be shaped and positioned separately before being assembled into the electrode body C. Specifically, the partition B is positioned twice by the first shaping module 12, and the fluid flow frame A is positioned twice by the second shaping module 16. Then, the two are assembled at the assembly station b2, which helps to improve the assembly accuracy and ensure the assembly quality of the electrode body C. At the same time, the pre-assembly module 1 has a reasonable structural layout. The secondary positioning and assembly path length of the partition B is basically the same as that of the fluid flow frame A. The secondary positioning movement path of the partition B is perpendicular to the assembly movement path of the partition B, and the secondary positioning movement path of the partition B is perpendicular to the secondary positioning movement path of the fluid flow frame A. The assembly movement path of the partition B is perpendicular to the assembly movement path of the fluid flow frame A. Based on this, the movement paths of the partition B and the fluid flow frame A on the first frame 11 form a rectangular structure layout. The travel base plates of the partition B and the fluid flow frame A from the storage area to the assembly station b2 are consistent, which is conducive to the efficiency matching of the mechanism for transferring the two and saves the assembly space of the mechanism.

[0013] In this embodiment, the partition B and the flow frame A are bonded together with UV adhesive. A second adhesive application module 13 is mounted on the first frame 11 for applying adhesive to the bonding surface of the partition B on the flow frame A. Figure 2 and Figure 3 As shown, the second glue application module 13 is located on the movement path of the second shaping module 16. Optionally, the second glue application module 13 can be an existing dispensing mechanism, as long as it can perform the function of dispensing glue on the liquid flow frame A located on the second shaping module 16.

[0014] like Figure 4 As shown, the first shaping module 12 includes a first shaping plate 121 disposed on the first frame 11. A first through hole 1211 is disposed through the first shaping plate 121. A first reference block 122 and a first pressing block 123 are disposed at intervals on the first shaping plate 121, as well as a second reference block 124 and a second pressing block 125. The first pressing block 123 can move closer to or away from the first reference block 122, and the second pressing block 125 can move closer to or away from the second reference block 124. The movement direction of the first pressing block 123 is perpendicular to the movement direction of the second pressing block 125. In this embodiment, the first clamping block 123 is disposed at the edge of the first through hole 1211, the first reference block 122 and the first clamping block 123 are spaced apart in the first direction X, that is, in the width direction of the partition B, and the second reference block 124 and the second clamping block 125 are spaced apart in the second direction Y, that is, in the length direction of the partition B. The first clamping block 123 and the second clamping block 125 are both driven by a cylinder (not shown in the figure) disposed on the first shaping plate 121.

[0015] like Figure 2As shown, the first transfer mechanism 14 includes a first gantry 141 mounted on a first frame 11. A first transfer frame 142 is movably mounted on the first gantry 141 along the second direction Y or the opposite direction of the second direction Y via a linear module. A first upright 143 is movably mounted on the first transfer frame 142 along the vertical direction via a linear module. A first suction cup for gripping the liquid flow frame A is mounted on the first upright 143. Here, the first upright 143 and the first suction cup constitute the first transfer assembly.

[0016] like Figure 2 and Figure 5 As shown, the second transfer mechanism 15 includes a second gantry frame 151, on which a second transplanting assembly 150 is movably mounted; the second transplanting assembly 150 includes a second upright frame 153, on which an integrated plate 154 is disposed, and on which at least one suction cup assembly 155 is mounted. In this embodiment, a second transfer frame 152 is disposed between the second transplanting assembly 150 and the second gantry frame 151. Specifically, the second transfer frame 152 is movably mounted on the second gantry frame 151 along the first direction X via a linear module, and the second upright frame 153 is movably mounted on the second transfer frame 152 along the vertical direction via a linear module. The suction cup assembly 155 is used to grip the partition B.

[0017] like Figure 5 As shown, the integrated plate 154 is provided with two sets of suction cup assemblies 155 to simultaneously grip the two partitions B. Each set of suction cup assembly 155 includes two suction cup assemblies 155, corresponding to the two ends of the partition B along its length.

[0018] Furthermore, such as Figure 6As shown, the suction cup assembly 155 includes two parallel guide rods 1551, which are fixedly mounted on the integrated plate 154. A first limiting block 1552 and an adjusting slider 1553 are disposed on each guide rod 1551. The first limiting block 1552 is fixedly mounted on the guide rod 1551, and the adjusting slider 1553 is slidably mounted along the axial direction of the guide rod 1551. A return spring 1554 is disposed between the first limiting block 1552 and the adjusting slider 1553. The suction cup assembly 155 also includes an adjusting rod 1555, at which... Between the two guide rods 1551, the end of the adjusting rod 1555 is rotatably connected to the corresponding adjusting slider 1553. A gripping suction cup 15551 is mounted on the adjusting rod 1555. A drive cylinder 1556 is hinged to the integrated plate 154. A connecting rod 15552 is disposed on the adjusting rod 1555, and the drive cylinder 1556 is rotatably mounted on the connecting rod 15552. The connection point between the drive cylinder 1556 and the integrated plate 154 is defined as the first hinge point, and the first limiting block 1552 is located between the adjusting slider 1553 and the first hinge point. In this embodiment, the drive cylinder 1556 is hinged to the integrated plate 154 via a hinge shaft N, and the first hinge point is located on the central axis of the hinge shaft N. In this embodiment, preferably, the guide rods 1551 corresponding to the two suction cup assemblies 155 at both ends of the same partition B can be integral, specifically as follows... Figure 6 As shown, in the second direction Y, the two corresponding guide rods 1551 are coaxial and integrally formed, and this integral design helps to improve the rigidity of the suction cup assembly 155. Of course, in another embodiment, in the second direction Y, the two corresponding guide rods 1551 can also be parallel and staggered in the first direction X.

[0019] In use, after the gripping suction cup 15551 grips the partition B, the driving cylinder 1556 operates, causing the adjusting rod 1555 to rotate. At this time, the partition B bends, which facilitates the effective separation of the upper and lower partitions B. Preferably, in this embodiment, two suction cup assemblies 155 are used for the same partition B, so both ends of the partition B are gripped, and the partition B bends downward or upward as a whole. Therefore, the length of the partition B is shortened in the second direction Y. At this time, the adjusting slider 1553 slides along the guide rod 1551 toward the first limiting block 1552 to compensate for the shortened distance of the partition B, which can prevent the suction cup assembly 155 from jamming. During this process, the return spring 1554 is compressed by the adjusting slider 1553 and the first limiting block 1552, which is conducive to the reset of the adjusting slider 1553.

[0020] In use, the drive cylinder 1556 can extend and retract multiple times in a short period of time to better separate the two adjacent partitions B.

[0021] It should be noted that partition B is stacked in the second storage area a2, and partition B can be bent by external force.

[0022] Preferably, in order to improve the rigidity of the suction cup assembly 155, for the same suction cup assembly 155, the two first limiting blocks 1552 on the two guide rods 1551 spaced apart in the first direction X are integrally set.

[0023] In this embodiment, the two guide rods 1551 of the same suction cup assembly 155 are connected by a fixing block 1557.

[0024] In this embodiment, the connecting rod 15552 is parallel to the adjusting rod 1555, and the adjusting rod 1555 is provided with an extension rod 1558. The connecting rod 15552 is connected to the adjusting rod 1555 through the extension rod 1558.

[0025] In this embodiment, a second limiting block 1559 is fixedly installed on the guide rod 1551, and the adjusting slider 1553 is located between the first limiting block 1552 and the second limiting block 1559. The first limiting block 1552 and the second limiting block 1559 are used together to limit the adjusting slider 1553.

[0026] like Figures 7 to 9 As shown, the second shaping module 16 includes a lower substrate 161 and an upper substrate 162. Both the upper substrate 162 and the lower substrate 161 are slidably connected to the first frame 11 via a slide rail slider assembly. In the vertical direction, the lower substrate 161 is located between the upper substrate 162 and the first frame 11. A second shaping plate 163 is disposed on both the upper substrate 162 and the lower substrate 161. A third reference block 1632 and a third pressing block 1631, as well as a fourth reference block 1634 and a fourth pressing block 1633 are disposed on the second shaping plate 163 at intervals. The third pressing block 1631 can move closer to or further away from the third reference block 1632, and the fourth pressing block 1633 can move closer to or further away from the fourth reference block 1634. The movement direction of the third pressing block 1631 is perpendicular to the movement direction of the fourth pressing block 1633. In this embodiment, the second shaping module 16 has two transfer platforms consisting of a lower substrate 161 and an upper substrate 162. Since they are staggered in the vertical direction, their movements in the first direction X do not interfere with each other, which can improve work efficiency.

[0027] In this embodiment, both the lower substrate 161 and the upper substrate 162 are driven by a synchronous belt (not shown in the figure) disposed on the first frame 11.

[0028] In this embodiment, as Figure 8 and Figure 9As shown, the third clamping block 1631 and the third reference block 1632 are references to each other, and the fourth clamping block 1633 and the fourth reference block 1634 are references to each other. In use, the third clamping block 1631 and the third reference block 1632 are driven to move closer to each other or further away from each other by the first clamping cylinder 1635 mounted on the second shaping plate 163, and the fourth clamping block 1633 and the fourth reference block 1634 are driven to move closer to each other or further away from each other by the second clamping cylinder 1636 mounted on the second shaping plate 163.

[0029] In this embodiment, the third clamping block 1631 and the third reference block 1632 are both connected to the first clamping cylinder 1635 via the first extension rod 1637, and the fourth clamping block 1633 and the fourth reference block 1634 are both connected to the second clamping cylinder 1636 via the second extension rod 1638. The first extension rod 1637 is parallel to the first direction X, and the second extension rod 1638 is parallel to the second direction Y. Both the first extension rod 1637 and the second extension rod 1638 are slidably connected to the second shaping plate 163 via linear bearings.

[0030] Since the second shaping plate 163 on the upper substrate 162 and the lower substrate 161 has the same height in the vertical direction at the feeding station b1, the assembly station b2 and the station corresponding to the second adhesive module 13, preferably, the second shaping plate 163 on the upper substrate 162 is fixedly assembled with the upper substrate 162, and the second shaping plate 163 on the lower substrate 161 is adjustablely assembled with the lower substrate 161, specifically, the second shaping plate 163 on the lower substrate 161 can be adjusted in the vertical direction.

[0031] Specifically, such as Figure 8 and Figure 9 As shown, a first guide rod 1639 extending vertically is disposed on a second shaping plate 163 located on the lower substrate 161. The first guide rod 1639 passes through the lower substrate 161 and is slidably connected to it. A driving member 1611 is disposed on the lower substrate 161 for driving the second shaping plate 163 located on the lower substrate 161 to move vertically. Preferably, the driving member 1611 is a cylinder.

[0032] like Figure 2 and Figure 10 As shown, the third transfer mechanism 17 includes a third gantry 171 and a third transfer assembly 172 movably mounted on the third gantry 171 along the second direction Y via a linear module; specifically, as Figure 10As shown, the third transplanting assembly 172 includes a third upright 1721, which is movably mounted on the third gantry 171 along the second direction Y via a linear module. An upper mounting plate 1722 is disposed on the third upright 1721, and a lower mounting plate 1723 is disposed on the lower side of the upper mounting plate 1722. A second guide rod 1725 extending in the vertical direction is disposed on the lower mounting plate 1723. The second guide rod 1725 passes through the upper mounting plate 1722 and is slidably connected to the upper mounting plate 1722 via a linear bearing. An assembly cylinder 1724 for driving the lower mounting plate 1723 to move in the vertical direction is disposed on the upper mounting plate 1722. A second suction cup 1726 for gripping the partition B is disposed on the lower mounting plate 1723. A UV lamp 1727 for curing UV adhesive is disposed on the lower mounting plate 1723. In use, after the second suction cup 1726 picks up the partition B on the first shaping module 12, it moves along the second direction Y to the assembly station b2. Then, the assembly cylinder 1724 drives the mounting plate 1723 to move downward so that the partition B is attached to the liquid flow frame A. It should be noted that the liquid flow frame A at the assembly station b2 has been coated with UV glue by the second glue application module 13. After the partition B is attached to the liquid flow frame A, the UV lamp 1727 irradiates the UV glue so that the partition B and the liquid flow frame A are quickly bonded together.

[0033] like Figure 2As shown, the pre-assembled module 1 also includes a transfer mechanism 18 disposed on the first frame 11. The transfer mechanism 18 includes a transfer platform 181 movably disposed on the second frame 21 along the second direction Y. Specifically, the transfer platform 181 is slidably mounted to the first frame 11 via a slide rail slider assembly and is driven by a synchronous belt disposed on the first frame 11 to move along the second direction Y. In this embodiment, the transfer mechanism 18 is located downstream of the assembly station b2 along the first direction X, and is used to reject NG electrode bodies C and send qualified electrode bodies C to the next station. Specifically, the transfer mechanism 18 also includes a first detection component 182, a fourth transplanting component 183, a fifth transplanting component 184, a fourth gantry 185, and a fifth gantry 186. The fourth gantry 185 and the fifth gantry 186 are spaced apart along the second direction Y. The first detection component 182 is a CCD camera, which is movably mounted on the fourth gantry 185 along the first direction X via a linear module. The transfer platform 181 can move along the second direction Y and pass through the space below the fourth gantry 185. The fourth transplanting component 183 is mounted on the fourth gantry 185. The fifth transplanting component 184 is movably mounted on the fifth gantry 186 along the first direction X via a linear module. In use, the fifth transfer assembly 184 transfers the electrode body C formed by the liquid flow frame A and the partition B of the assembly station b2 to the transfer platform 181. The transfer platform 181 moves in the opposite direction of the second direction Y to the first detection assembly 182 for photographic detection. The qualified electrode body C is then transferred to the next station by the fifth transfer assembly 184, specifically to the flipping module 2 for flipping. The unqualified electrode body C, i.e. NG, is transferred to the fourth transfer assembly 183 by the transfer platform 181 for unloading.

[0034] Optionally, the fourth transplant component 183 and the fifth transplant component 184 can have the same structure as the first transplant component, or they can be modified based on the first transplant component. Specifically, they can grasp the liquid flow frame A or the electrode body C by negative pressure adsorption, and the height of the electrode body C can be adjusted in the vertical direction. This is existing technology and will not be described in detail here.

[0035] like Figure 11As shown, the flipping module 2 includes a second frame 21, within which a buffer space 211 is configured. The buffer space 211 contains a buffer plate 22 that is vertically adjustable. A flipping frame 24 is rotatably mounted on the second frame 21, and a gripper assembly 25 for grasping the electrode body C is mounted on the flipping frame 24. In use, the fifth transfer assembly 184 moves along the first direction X to transfer the qualified electrode body C to the flipping frame 24, where it is gripped and fixed by the gripper assembly 25. Subsequently, the fifth transfer assembly 184 resets, and after the flipping frame 24 flips 180°, the buffer plate 22 moves upwards vertically to support the electrode body C on the gripper assembly 25, continuously stacking and buffering the electrode bodies C. The buffered electrode bodies C are subsequently fed into the first adhesive application module 3 for dispensing adhesive. Buffering the electrode bodies C ensures the continuity of subsequent processing and guarantees production efficiency.

[0036] Specifically, a lifting frame 23 is slidably mounted vertically on the side wall of the buffer space 211 via a slide rail slider assembly. The lifting frame 23 is driven by a linear module set on the side wall of the buffer space 211, and the buffer plate 22 is mounted on the lifting frame 23.

[0037] In this embodiment, a shaft bracket 212 is mounted on the second frame 21, and a tilting frame 24 is rotatably mounted on the shaft bracket 212. The shaft bracket 212 can be understood as part of the second frame 21, used to raise the tilting frame 24 vertically to avoid interference. Furthermore, the tilting frame 24 is positioned above the buffer space 211, and its rotation axis is parallel to the second direction Y. Preferably, the tilting frame 24 is a rectangular frame. When the electrode body C is grasped, the electrode body C is positioned within the tilting frame 24, i.e., the rectangular frame.

[0038] like Figure 12 As shown, the gripper assembly 25 includes a mounting base 251 disposed on the flipping frame 24, a fixed base 252 rotatably mounted on the mounting base 251, and a third suction cup 253 disposed on the fixed base 252. In this embodiment, the axis of rotation of the fixed base 252 relative to the mounting base 251 is parallel to the first direction X. In use, the flipping frame 24 is in its initial state, at which time the third suction cup 253 is facing upwards. The fifth transfer assembly 184 transfers the electrode body C to above the gripper assembly 25, at which time the third suction cup 253 is below the electrode body C. After the third suction cup 253 grips the electrode body C, the fifth transfer assembly 184 resets, the flipping frame 24 rotates 180°, at which point the third suction cup 253 is above the electrode body C, the buffer plate 22 moves upwards to receive the electrode body C, and the third suction cup 253 detaches from the electrode body C. When it is necessary to transfer the electrode body C on the buffer plate 22 to the next station, the buffer plate 22 moves upward and the fixed seat 252 rotates 90° relative to the mounting seat 251 to facilitate the removal of the electrode body C from the buffer plate 22.

[0039] Optionally, the mounting plate is rotatably mounted on the mounting base 251 via a pneumatic finger 254. Here, the pneumatic finger 254 is a 180° opening and closing type pneumatic finger 254.

[0040] like Figure 13 As shown, the first adhesive coating module 3 includes a third frame 31. At least one dispensing station and at least one inspection station are sequentially arranged on the third frame 31 along the first direction X. The dispensing station is equipped with a dispensing assembly 34, and the inspection station is equipped with a second inspection assembly 35. A sixth gantry 32 is configured on the third frame 31. A sixth transfer assembly 33 is movably arranged on the sixth gantry 32 along the first direction X via a linear module. The sixth transfer assembly 33 is used to transfer the electrode body C from the self-flipping module 2 to the first adhesive coating module 3, and to transfer the electrode body C between dispensing stations or between a dispensing station and an inspection station. Figure 13 As shown, in this embodiment, there are two dispensing stations and one inspection station. The structure of the sixth transfer component 33 is the same as that of the fifth transfer component 184. Optionally, multiple sixth transfer components 33 are spaced apart in the first direction X to reduce the travel distance of the sixth transfer component 33 in transporting the electrode body C.

[0041] In this embodiment, the dispensing assembly 34 is a conventional dispensing mechanism used to dispense adhesive onto the side opposite to the assembly partition B of the electrode body C, i.e., the fluid flow frame A. The second detection assembly 35 is a CCD detection assembly, which is existing technology and will not be described in detail here.

[0042] like Figure 14 and Figure 15 As shown, in this embodiment, both the dispensing station and the inspection station are equipped with fixture assemblies 36. The fixture assembly 36 includes a lower base plate 361 and an upper base plate 362 spaced apart vertically. The lower base plate 361 and the upper base plate 362 are connected by an extension post 360. Two sets of length limiting shafts 363 are spaced apart along the length direction of the electrode body C on the upper base plate 362, and two sets of width limiting shafts 364 are spaced apart along the width direction of the electrode body C. The two sets of length limiting shafts 363 and the two sets of width limiting shafts 364 can move closer or further apart. The electrode body C is placed on the upper base plate 362 and within the space defined by the length limiting shafts 363 and the width limiting shafts 364. In this embodiment, the width direction of the electrode body C is parallel to the first direction X, and the length direction of the electrode body C is parallel to the second direction Y. There are two length limiting shafts 363 and two width limiting shafts 364 in each set.

[0043] Specifically, such as Figure 15As shown, the same set of length limiting shafts 363 are mounted on the same first integrated rod 3631, and the same set of width limiting shafts 364 are mounted on the same second integrated rod 3641. The first integrated rod 3631 and the second integrated rod 3641 can be slidably mounted on the side of the upper base plate 362 facing the lower base plate 361 through the slide rail slider assembly, and are driven by the clamping cylinder set on the upper base plate 362 through the third extension rod 3632 and the fourth extension rod 3642 respectively. The principle is the same as that of the third pressing block 1631 and the third reference block 1632, as well as the fourth pressing block 1633 and the fourth reference block 1634, which will not be repeated here.

[0044] It should be noted that the upper base plate 362 is provided with corresponding clearance grooves so that the length limiting shaft 363 and the width limiting shaft 364 can extend above the upper base plate 362 and move and adjust in the horizontal direction. In use, the electrode body C is placed on the upper surface of the upper base plate 362 and positioned by the length limiting shaft 363 and the width limiting shaft 364.

[0045] Furthermore, the lower base plate 361 is provided with length pressure plates 365 at both ends of the electrode body C along the length direction. The two length pressure plates 365 can be close to each other or far apart. The upper base plate 362 is provided with a second through hole. The lower base plate 361 is provided with two width pressure plates 366 along the width direction of the electrode body C. The width pressure plates 366 can extend through the second through hole to the top of the electrode body C, and are used to fix the electrode body C inside the shaping hole of the electrode body C, i.e., the liquid flow frame A.

[0046] like Figure 16 As shown, a first transfer plate 3651 is slidably mounted on the lower base plate 361 along the length direction of the electrode body C, i.e., the second direction Y, via a slide rail slider assembly. A length pressure plate 365 is adjustable in the vertical direction on the first transfer plate 3651 via a cylinder. Figure 17 As shown, a second transfer plate 3661 is slidably mounted on the lower base plate 361 along the width direction of the electrode body C, i.e., the first direction X, via a slide rail slider assembly. A width pressure plate 366 is adjustable on the second transfer plate 3661 in the vertical direction via a cylinder.

[0047] Here, the electrode body C is fixed at the dispensing station and the inspection station by the fixture assembly 36, which facilitates dispensing and photographic inspection. After inspection, the electrode body C is transferred to the conveying module 4 by the sixth transfer assembly 33. The conveying module 4 is a conveyor belt that transfers the electrode body C to the assembly module 5, where it is assembled manually or mechanically to form an electrode stack.

[0048] It should be noted that the mechanism mentioned above, being able to move in the first direction X, also means that it can move in the opposite direction of the first direction X; correspondingly, being able to move in the second direction Y, also means that it can move in the opposite direction of the second direction Y.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
