Referring to fig. 1 and 2, a side surface of the bottom plate 1 close to the panel 2 is provided with a limiting groove 11 for the stop block assembly 4 to slide.
Referring to fig. 4, the handle 43 is formed by connecting two cylinders with different diameters, and the cylinders with different diameters are connected to form the handle, so that whether the limiting block is clamped into the guide positioning pin can be judged by the change of the diameter of the handle.
Referring to fig. 1, a limit adjusting screw 10 is respectively disposed at each of four corners of the panel 2 to limit the panel during the restoration process, and the parallelism between the panel and the bottom plate is adjusted by adjusting the tightness of the screw.
The specific application of this example is as follows:
when the bipolar plate needs to be attached with the sealing ring, the sealing ring is placed in the sealing ring groove 5, the position and the shape of the sealing ring are adjusted, then a worker shifts the stopper handle 43, the limiting block 41 and the connecting block 42 extend into the space between the bottom plate 1 and the panel 2, and the limiting blocks 42 are respectively clamped into the outer walls of the corresponding guide positioning pins 3 (the limiting blocks 42 are positioned between the bosses 21 and the bottom plate), so that the panel 2 and the bottom plate 1 are kept relatively fixed, and when the stopper assembly 4 is inserted, the worker can judge whether the limiting blocks are completely clamped between the bosses and the bottom plate according to the relative positions of parting surfaces at different diameters of the handle 43 and the edge line of the panel;
after the sealing ring is placed, aligning the positioning hole on the bipolar plate coated with the dehydration or glue layer with the positioning pin 6 on the panel 2 and putting down the bipolar plate, so as to avoid the bipolar plate from deviating, and then uniformly applying force to extrude the bipolar plate so that the bipolar plate is effectively attached to the bipolar plate, and at the moment, due to the limiting action of the limiting block 41, the position of the panel 2 can not be changed when being pressed;
and the handle 43 is pulled out, so that the limiting block 41 is separated from the guide positioning pin 3 and taken out, the left side and the right side of the panel 2 are pressed by using two hands to apply force downwards, the panel 2 moves downwards, the ejector rod 7 jacks up the bipolar plate attached with the sealing ring, and the polar plate is taken out to finish the operation.
To sum up, the utility model provides a pair of bipolar plate sealing washer laminating device, the utility model discloses a set up bottom plate, panel, guide locating pin and dog subassembly, and set up the sealing washer slot at the panel surface, make when bipolar plate laminating sealing washer, earlier place the sealing washer slot internal with the sealing washer, then establish the bipolar plate lid that has coated dehydration or glue film on the panel and even application of force in order to guarantee that sealing washer and bipolar plate laminate completely, just so can accomplish the installation of bipolar plate sealing washer, whole installation is simple and convenient, reduce workman's intensity of labour, and can also promote the laminating quality of bipolar plate sealing washer.
The above mentioned is only the embodiment of the present invention, and the patent scope of the present invention is not limited thereby, and all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
