DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0036] During production, bipolar plates and membrane electrodes are stored in a stacked state in a material frame for feeding. When stacking, the bipolar plates and membrane electrodes are stacked alternately in sequence to the required height or number of sheets by a manipulator with a vacuum adsorption component. Because the surface of the sheet is sticky, there is a situation where the sheets are stuck together and not separated during the process of sucking the sheets in the material frame, and the stuck sheets need to be separated manually. In order to avoid the sheets from sticking together, a paper separator is usually set between the sheets. However, for the material frame with a paper separator, it is inevitable that the paper separator and the sheet will stick together and not separate during the adsorption process, and the paper separator needs to be removed manually. The existing material frame structure has a single function and needs further development.

[0037] Example

[0038] In response to the above problems, this embodiment provides a hydrogen fuel cell sheet turnover device. By setting a separation brush 360, the side of the sheet can be brushed and scraped during the process of moving the sheet away from the material frame, thereby brushing off the stuck sheets or stuck separators to solve the problem of sheet sticking during suction.

[0039] like Figure 1-2 As shown, a hydrogen fuel cell sheet turnover device is used to stack sheets, the sheet 400 is a bipolar plate or a membrane electrode, and the hydrogen fuel cell sheet turnover device includes:

[0040] The frame 300 has a space for stacking and accommodating sheets 400. A separation brush 360 is provided on each side of the upper end of the frame 300. The bristles of the separation brush 360 extend into the space. The bristles can brush and scrape the sides of the sheets 400 during the process of the sheets 400 moving away from the material frame, thereby brushing off the stuck sheets 400 or stuck separators to solve the problem of the sheets 400 sticking during suction.

[0041] In this embodiment, the frame 300 includes a bottom plate 310, an L-shaped vertical rod 340, a long side plate 320 and a short side plate 330;

[0042] The long side panels 320 are arranged on the two long sides of the bottom plate 310, and the short side panels 330 are arranged on the two short sides of the bottom plate 310. The two long side panels 320 and the two short side panels 330 form a rectangular frame, and an L-shaped vertical rod 340 is arranged at each of the four inner corners of the rectangular frame.

[0043] A separation brush 360 is installed on the top of each upright pole, and each separation brush 360 is located on a different side of the bottom plate 310 .

[0044] In actual applications, since the surface of the sheet 400 is sticky, it is inevitable that the separation paper and the sheet 400 are stuck together and not separated during the adsorption process. For this reason, the frame 300 is provided with a separation brush 360. In the process of the sheet 400 moving away from the frame 300, the four separation brushes 360 can respectively brush and scrape the four sides of the sheet 400. If there is separation paper stuck on the bottom surface of the sheet 400, the brushing action of the separation brush 360 can separate the separation paper from the sheet 400. At the same time, for the material frame without separation paper, the separation brush 360 can separate multiple sheets 400 that are stuck together, thereby solving the problem of the sheets 400 sticking together during absorption.

[0045] In this embodiment, both ends of the short side plate 330 and both ends of the long side plate 320 are respectively provided with horizontal strip holes A331 and horizontal strip holes B321;

[0046] The two sides of the long side plate 320 are connected to the vertical poles on the same side via screws penetrating the horizontal bar holes B321;

[0047] The two end surfaces of the long side plate 320 are connected to the short side plate 330 on the same side via screws penetrating the horizontal strip holes A331;

[0048] The bottom plate 310 is provided with a horizontal adjustment hole 311 along the short side direction, and the bottom ends of the long side plates 320 are connected via screws penetrating the horizontal adjustment hole 311 .

[0049] In practical applications, through the design of the horizontal bar holes A331, the horizontal bar holes B321 and the horizontal adjustment holes 311, the frame 300 can be adaptively adjusted according to the size of the accommodated sheet 400 and the spacer paper, and the frame 300 has strong compatibility.

[0050] In this embodiment, a lifting plate 370 is provided at the inner bottom of the frame 300;

[0051] The bottom plate 310 is provided with a lifting and clearing opening 313 in the middle thereof for the lifting end of the lifting assembly 200 to pass through. When the lifting plate 370 is lifted or lowered, the lifting end of the lifting assembly 200 passes through the lifting and clearing opening 313 and abuts against the bottom surface of the lifting plate 370 .

[0052] In actual application, the plane height of the manipulator for sucking the sheet 400 is fixed, and the lifting assembly 200 is set to gradually lift (load) or lower (collect) the lifting plate to ensure the smooth suction and transplantation of the sheet 400 or the separator. For example, for the frame 300 full of sheets for loading, the lifting assembly 200 makes the lifting plate 370 located at the lower limit position and gradually lifts the lifting plate 370; for example, for the empty frame 300 for storing materials, the lifting assembly 200 makes the lifting plate 370 located at the upper limit position and gradually moves the lifting plate 370 downward.

[0053] In this embodiment, at least two positioning pins 312 are provided on the bottom plate 310, and positioning guide holes 371 cooperating with the positioning pins 312 are provided on the lifting plate 370. The positioning pins 312 cooperate with the positioning guide holes 371 to position the lifting plate 370 to ensure the level of the lifting plate 370, thereby preventing the lifting plate 370 from tilting due to the tilt of the lifting plate 370 when lifting, causing the sheet 400 or the separator paper on the top surface to tilt, resulting in the material falling off during suction and transplanting due to the inability to suck or the unreliable suction.

[0054] In this embodiment, a handle 322 is provided on the long side plate 320 to facilitate workers to hold and move the material frame.

[0055] In this embodiment, in order to improve the convenience of size adjustment, scale lines 350 are provided on both the long side and the short side of the bottom plate 310 .

[0056] like Figure 3-4 As shown, this embodiment also provides a feeding mechanism:

[0057] It includes a frame 100, a material frame and a lifting assembly 200;

[0058] The frame 100 has a station for placing a material frame;

[0059] The lifting assembly 200 is installed on the frame 100 and located at the workstation. The lifting assembly 200 is located below the material frame placed on the workstation.

[0060] The material frame is the above-mentioned hydrogen fuel cell sheet turnover device.

[0061] In this embodiment, the lifting assembly 200 includes a top plate 210 and a lifting linear module 230 , and the top plate 210 is installed at the moving end of the lifting linear module 230 .

[0062] In this embodiment, the lifting linear module 230 is a through-type screw motor module, and the through-type screw motor module is installed on the alignment lifting plate 220;

[0063] The alignment lifting plate 220 is installed on the frame 100 via a lifting cylinder 240. Positioning columns 221 are provided at the four corners of the alignment lifting plate 220. A positioning groove 314 cooperating with the positioning column 221 is provided at the bottom of the bottom plate 310.

[0064] When the lifting assembly 200 is not working, the lifting linear module 230 makes the top plate 210 in the lower limit position. At the same time, the lifting cylinder 240 makes the top plate 210 located below the material frame. When the lifting assembly 200 is working, the lifting cylinder 240 makes the lifting linear module 230 rise to its position as a whole. At this time, the top of the positioning column 221 is inserted into the positioning groove 314 to complete the alignment. After the alignment, the top surface of the top plate 210 is in contact with the bottom surface of the lifting plate 370.
