The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0032] Please refer to Figures 1 to 10, A fluid flow frame and separator plate assembly device for a fuel cell, including a reference plate 3, a shaping plate 4, and a grasping mechanism 2, where: The reference plate 3 is provided with an assembly hole 31 running through it, which is used to expose the area on the fluid flow frame a for assembling with the separator plate b; The shaping plate 4 is movably arranged on the reference plate 3 and is used to carry the separator plate b. The shaping plate 4 is provided with a first shaping component and a second shaping component. The first shaping component is used to limit the separator plate b in the first direction X, and the second shaping component is used to limit the separator plate b in the second direction Y. The first direction X is perpendicular to the second direction Y; The grasping mechanism 2 is on the side of the shaping plate 4 away from the reference plate 3 and is used to transfer the separator plate b to the assembly hole 31. In this embodiment, the fluid flow frame a is arranged below the reference plate 3, and the area on the fluid flow frame a for installing the separator plate b is exposed upward through the assembly hole 31. The transferred separator plate b is first placed on the shaping plate 4, and through the cooperation of the first shaping component and the second shaping component, the posture of the separator plate b is adjusted in the first direction X and the second direction Y on the shaping plate 4 to make it reach a predetermined state. Then, the grasping mechanism 2 grasps the separator plate b with adjusted posture, transfers it to the installation hole, and assembles it on the fluid flow frame a. Here, through the coordinated cooperation of the grasping mechanism 2, the shaping plate 4, the first shaping component, and the second shaping component, the assembly accuracy of the separator plate b and the fluid flow frame a can be effectively improved. Specifically, the operation of adjusting the posture of the separator plate b on the shaping plate 4 can ensure that the grasping mechanism 2 grasps the separator plate b with high precision, and further ensure that the subsequent grasping mechanism 2 assembles the separator plate b and the fluid flow frame a with high precision, which is beneficial to reducing the defective rate of the fuel cell.

[0033] In this embodiment, the shaping plate 4 being movably arranged on the reference plate 3 can more reasonably layout the spatial positions of the various components of this assembly device during use. Specifically, by adjusting the position of the shaping plate 4 on the reference plate 3, it can effectively avoid interference between the shaping plate 4 and the grasping mechanism 2, which is beneficial to the picking and placing of the separator plate b on the shaping plate 4.

[0034] As Figure 7 and Figure 8 shown, the first shaping component includes a first reference block 51 and a first pressing block 52, and the first pressing block 52 and the first reference block 51 can approach or move away from each other; The second shaping component includes a second reference block 53 and a second pressing block 54, and the second reference block 53 and the second pressing block 54 can approach or move away from each other. In this embodiment, cylinders corresponding to the reference block and the pressing block are arranged on the shaping plate 4, and the reference block and the pressing block are arranged at the telescopic ends of the cylinders. The relative positions of the reference block and the pressing block are adjusted by the cylinders to drive the separator plate b to move to a predetermined posture on the shaping plate 4.

[0035] Specifically, the cylinders corresponding to the first reference block 51 and the first pressing block 52 telescope along the first direction X, and the cylinders corresponding to the second reference block 53 and the second pressing block 54 telescope along the second direction Y.

[0036] Furthermore, as Figure 7 shown, a guide rail beam 32 is provided on the reference plate 3, and the guide rail beam 32 extends along the first direction X; the shaping plate 4 is slidably mounted on the guide rail beam 32; a first driving member 33 is arranged on the guide rail beam 32 or the reference plate 3, and the first driving member 33 is used to drive the guide rail beam 32 to slide relative to the shaping plate 4 along the first direction X. In this embodiment, optionally, there are two shaping plates 4, and the two shaping plates 4 are mirror-symmetrically arranged in the first direction X, and there are two first driving members 33 corresponding to the two shaping plates 4. Here, the shaping plate 4 is slidably connected to the guide rail beam 32 through a slide rail-slider assembly. In this embodiment, the first driving member 33 is a telescopic member, including but not limited to a cylinder, a hydraulic cylinder or an electric push rod. The first driving member 33 is mounted on the inner side surface of the guide rail beam 32. The first driving member 33 drives the corresponding shaping plate 4 to move.

[0037] In this embodiment, in order to improve the stability of the movement of the shaping plate 4, there are two guide rail beams 32, and the two guide rail beams 32 are spaced apart in the second direction Y, and the shaping plate 4 straddles the two guide rail beams 32.

[0038] In another embodiment, the first driving member 33 can also be a left-right rotating lead screw. The left-right rotating lead screw is rotatably mounted on the guide rail beam 32, and the left-right rotating lead screw extends along the first direction X. The shaping plates 4 at both ends of the left-right rotating lead screw are threadedly connected to the left-right rotating lead screw, and a motor is arranged on the guide rail beam 32 to drive the left-right rotating lead screw to rotate, so as to realize the synchronous movement of the two shaping plates 4 to make them approach or move away from each other synchronously. In this way, the position adjustment efficiency of the shaping plate 4 can be improved.

[0039] As Figure 9 shown, an adjustment notch 42 is provided on the shaping plate 4, and the adjustment notch 42 corresponds to the first reference block 51, the first pressing block 52, the second reference block 53 and the second pressing block 54. The first reference block 51, the first pressing block 52, the second reference block 53 and the second pressing block 54 can be respectively embedded into the corresponding adjustment notch 42; transverse limiting surfaces 50 are arranged on the first reference block 51, the first pressing block 52, the second reference block 53 and the second pressing block 54, and the transverse limiting surfaces 50 face the partition plate b. A longitudinal limiting surface 41 is arranged on the shaping plate 4. In the third direction Z, the lowest point of the transverse limiting surface 50 is lower than the longitudinal limiting surface 41, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs. Such a setting can enable the reference block and the pressing block to have sufficient movement space in the transverse direction, that is, the first direction X and the second direction Y, so that the assembly equipment can adapt to the attitude adjustment of different specifications of the partition plate b. And the structural design that the lowest point of the transverse limiting surface 50 is lower than the longitudinal limiting surface 41 in the third direction Z can enable the working surface to be in full contact with the partition plate b, ensuring the reliability of the attitude adjustment of the partition plate b on the shaping plate 4.

[0040] It should be noted that the isolation plate b is attached to the longitudinal limiting surface 41. Here, the longitudinal direction is parallel to the third direction Z.

[0041] In this embodiment, the assembly device further includes a transfer tray 6 and a fixture 7. Among them, the transfer tray 6 is used to carry the liquid flow frame a, and the liquid flow frame a is located between the transfer tray 6 and the reference plate 3; the fixture 7 acts on the transfer tray 6 to make the liquid flow frame a fit or separate from the side surface of the reference plate 3 facing the transfer tray 6. The transfer tray 6 and the fixture 7 are designed separately, which can cooperate with the assembly line to efficiently transfer the liquid flow frame a combined with the transfer tray 6, and is beneficial to improving production efficiency. Specifically, first, the liquid flow frame a is assembled to the transfer tray 6 at other workstations, and then the transfer tray 6 is transferred through the assembly line to reach between the fixture 7 and the reference plate 3. Then, the fixture 7 makes the transfer tray 6 rise along the third direction Z and finally makes the liquid flow frame a fit to the lower side surface of the reference plate 3, waiting for the assembly of the isolation plate b. After the isolation plate b is assembled, the transfer tray 6 is transferred to other workstations through the assembly line for the next step of processing.

[0042] In this embodiment, the fixture 7 is used to lift the transfer tray 6 along the longitudinal direction, that is, the third direction Z.

[0043] As Figure 4 、 Figure 5 and Figure 8 shown, a plurality of limiting blocks 61 are arranged on the transfer tray 6, and the plurality of limiting blocks 61 enclose an assembly area, and the liquid flow frame a is located in the assembly area; a plurality of avoidance grooves 34 corresponding to the plurality of limiting blocks 61 one by one are penetrated through the reference plate 3. The limiting blocks 61 here are used to limit the liquid flow frame a so that it can be in a predetermined posture on the transfer tray 6 and does not shift during the transfer process. When the fixture 7 drives the transfer tray 6 to move upward along the third direction Z, the limiting blocks 61 are inserted into the avoidance grooves 34 so that the liquid flow frame a can be effectively attached to the reference plate 3.

[0044] In another embodiment, the limiting blocks 61 are adjustably arranged on the transfer tray 6. With this setting, the transfer tray 6 can be adapted to liquid flow frames a of different specifications. The adjustable structure of the limiting blocks 61 can refer to the installation structure of the reference block and the pressing block on the shaping plate 4 described above.

[0045] As Figure 1 and Figure 5As shown, the assembly device further includes a frame 1. The fixture 7 includes a fixed plate 71 and a movable plate 72. The reference plate 3 and the fixed plate 71 are fixedly installed on the frame 1. The movable plate 72 is located between the fixed plate 71 and the reference plate 3, and the movable plate 72 is used to support the transfer tray 6. A positioning pin 721 is arranged on the movable plate 72, and a positioning pin hole 62 adapted to the positioning pin 721 is arranged on the transfer tray 6. In this embodiment, the frame 1 includes four vertical columns 11, two first middle cross columns 12 and two second middle cross columns 13. The first middle cross column 12 extends along the first direction X and connects two adjacent vertical columns 11 in the first direction X. Correspondingly, the second middle cross column 13 extends along the second direction Y and connects two adjacent vertical columns 11 in the second direction Y, so that the structure of the frame 1 is stable. Here, the reference plate 3 is fixedly installed on the first middle cross column 12 through an extended plate 35. The frame 1 further includes two spaced inner mounting columns 14. The inner mounting columns 14 extend along the second direction Y and connect the two first middle cross columns 12. The fixed plate 71 is fixedly installed on the inner mounting columns 14. In this embodiment, the inner mounting columns 14 are located between the two second middle cross columns 13.

[0046] Specifically, as Figure 5 shown, when in use, the transfer tray 6 is placed on the movable plate 72, and the positioning pin 721 is inserted into the positioning pin hole 62 to realize the positioning of the transfer tray 6.

[0047] In this embodiment, a second driving member 73 is installed on the fixed plate 71. The second driving member 73 is used to drive the movable plate 72 to move along the third direction Z. The second driving member 73 includes, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.

[0048] In another embodiment, the second driving member 73 can also be installed on the frame 1.

[0049] To improve the stability of the movement of the movable plate 72, in this embodiment, as Figure 5 and Figure 6 shown, a first guide rod 722 is arranged on the movable plate 72. The first guide rod 722 penetrates through the fixed plate 71 and is slidably connected thereto. Specifically, the first guide rod 722 is slidably connected to the fixed plate 71 through a linear bearing. Here, the first guide rod 722 extends along the third direction Z. It plays a role in stabilizing the movable plate 72 during the process of the movable plate 72 being driven by the second driving member 73 to move along the third direction Z.

[0050] Optionally, a limiting plate 74 is arranged at one end of the first guide rod 722 away from the movable plate 72. A limiting pin 741 is arranged on the limiting plate 74. The fixed plate 71 is located between the movable plate 72 and the limiting pin 741. Here, the limiting pin 741 is used to cooperate with the fixed plate 71 to limit the maximum distance of the upward movement of the movable plate 72 along the third direction Z, so as to prevent a collision accident from occurring when the movable plate 72 moves upward along the third direction Z after the second driving member 73 gets out of control.

[0051] As Figure 1 shown, the frame 1 further includes a top beam 15 provided at the top of the vertical column 11. The top beam 15 extends along the second direction Y. There are two top beams 15, and a gantry beam 23 spans between the two top beams 15. The gantry beam 23 extends along the first direction X. In this embodiment, a first linear module 21 is configured on one of the top beams 15, and a first linear slide rail 22 is configured on the other top beam 15. One end of the gantry beam 23 is connected to the first linear module 21, and the other end is connected to the first linear guide rail. In this way, the movable assembly of the gantry beam 23 in the second direction Y can be realized.

[0052] The first linear module 21, the first linear slide rail 22, and the gantry beam 23 here all belong to the grasping mechanism 2. That is, the grasping mechanism 2 includes the first linear module 21, the first linear slide rail 22, and the gantry beam 23.

Among them, the second linear module 231 is installed on the gantry beam 23, the third linear module 24 is installed on the second linear module 231, and is driven by the second linear module 231 to move along the first direction X. The grasping part 25 is installed on the third linear module 24 and is driven by the third linear module 24 to move along the third direction Z. Here, through the mutual cooperation of the first linear module 21, the second linear module 231, and the third linear module 24, the position adjustment of the grasping part 25 in three-dimensional space can be realized to better grasp the isolation plate b and the liquid flow frame a for assembly.

[0053] Furthermore, as Figure 1 and Figure 10 shown, the grasping part 25 includes a vertical frame plate 251. The vertical frame plate 251 is installed on the third linear module 24. One end of the vertical frame plate 251 facing the reference plate 3 is configured with a main body plate 252, and a negative pressure suction cup is configured on the main body plate 252.

[0054] Even further, a third driving part 256 is provided on the main body plate 252. The grasping part 25 further includes a lower integrated board 253 and an upper integrated board 254. The main body plate 252 is located between the upper integrated board 254 and the lower integrated board 253. The negative pressure suction cup is installed on the lower integrated board 253. The third driving part 256 is used to drive the upper integrated board 254 to move along the third direction Z. The upper integrated board 254 and the lower integrated board 253 are connected by a second guide rod 255. The second guide rod 255 passes through the main body plate 252 and is slidably connected to it. The second guide rod 255 here extends along the third direction Z.

[0055] During use, the third module can realize the rapid movement of the isolation plate b grasped by the negative pressure suction cup in the third direction Z, while the third driving part 256 is used to realize the fine adjustment of the isolation plate b in the third direction Z. With such a setting, the working efficiency of the grasping mechanism 2 can be improved while ensuring the assembly accuracy of the isolation plate b.

[0056] Optionally, the third driving member 256 includes, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.
