[0003] The above-mentioned comparative documents and prior art present the following technical problems: Single cells are the core components of hydrogen fuel cell stacks, and the final step in single cell production is the curing of UV glue: after applying a circle of UV glue to the corresponding position on the bipolar plate, the MEA membrane electrode is aligned with the UV glue line and attached to the bipolar plate. The glue line is then pressed with a tool while UV light is applied to the glue line for a few seconds to cure it, thus completing the production of the single cell. Due to the previous manual lamination and curing process, the qualified rate of the produced single cells could not be guaranteed and the production efficiency was low. Therefore, a UV glue pressing and UV light curing mechanism was designed for use on an automated production line to improve the qualified rate and efficiency of single cell production.

[0023] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

[0025] Reference Figure 1-4The utility model provides a UV glue pressing ultraviolet light curing mechanism, including a frame 1, the overall shape of the frame 1 is an inverted L-shape, the function of the frame 1 is to unify the reference and fix all the parts used for pressing and curing to ensure its stability during normal operation, one end of the frame 1 is provided with a pressing position adjustment mechanism 5 on the top, and adjustment screws 6 are provided on both sides of the pressing position adjustment mechanism 5. The frame 1 and the pressing position adjustment mechanism 5 are connected by adjusting screws 6, and adjustment plates are provided at both ends of the pressing position adjustment mechanism 5. The shape of the adjustment plate is bow-shaped, and adjustment screws 6 are provided at both ends of the adjustment plate and the outer groove of the adjustment plate. The function of the pressing position adjustment mechanism 5 is to adjust the downward pressing position of the entire glass pressing plate so that its light-transmitting pressing position can be directly opposite to the position of the single-cell UV glue line, thereby ensuring the pressing and curing accuracy. A stroke-adjustable cylinder 7 is provided at the top center of the pressing position adjustment mechanism 5, and the top of the pressing position adjustment mechanism 5 is provided with an adjustable cylinder 7. The upper and lower floating mechanisms 4 are provided, and the stroke-adjustable cylinder 7 passes through the center of the pressing position adjusting mechanism 5 to the center of the upper and lower floating mechanisms 4. The upper and lower floating mechanisms 4 are in the shape of an I-shape, and there is a hollow groove in the center of the upper and lower floating mechanisms 4. Compression rods are provided at the four corners of the upper and lower floating mechanisms 4, and a spring 8 is provided on the outside of the center of the compression rod. The function of the upper and lower floating mechanisms 4 is to ensure that the entire pressing surface of the glass and the workpiece can be in full contact when the cylinder is extended and pressed, and there is no angle. At the same time, it also prevents the glass from breaking due to excessive pressure. An ultraviolet lamp 2 is provided on the outside of the spring 8, and a curing area-shaped translucent glass 3 is provided at the bottom of the ultraviolet lamp 2, which is preferably a curing area-shaped high-transmittance glass. The shape of the ultraviolet lamp 2 is a rectangle with a hollow groove in the center, and the hollow rectangular design in the middle is, first, a lighting area designed for the path of the UV glue line, and second, it is conducive to the heat dissipation of the ultraviolet lamp (the ultraviolet lamp tube is also equipped with a water cooling system). The compression rod extends from the hollow groove to the curing area shaped translucent glass 3, the curing area shaped translucent glass 3 is fitted with the ultraviolet lamp 2, and the length of the curing area shaped translucent glass 3 is longer than the ultraviolet lamp 2, and the hollow groove of the ultraviolet lamp 2 is provided with a connecting plate, and the two ends of the connecting plate are respectively connected to the ultraviolet lamp 2 and the curing area shaped translucent glass 3. The function of the ultraviolet lamp 2 is to emit ultraviolet rays of the required wavelength to irradiate the UV glue to make it cure quickly. The function of the curing area shaped translucent glass 3 is to press the MEA membrane electrode after applying the UV glue and flatten the UV glue. Here, there are high requirements for the strength and flatness of the pressed workpiece, and ultraviolet light should be avoided from irradiating places other than the glue line area. Therefore, the positions that do not require light transmission and pressing are roughened and shaped and sunken. At the same time, it can prevent the tempered glass from being pressed into the catalyst layer area in the middle of the MEA membrane electrode, thereby protecting the MEA membrane electrode catalyst layer.The cured area contoured light-transmitting glass 3 is used, and the cured area contoured light-transmitting glass 3 is used to press the MEA membrane electrode with UV glue, and the UV glue is flattened. Here, there are high requirements for the strength and flatness of the pressed workpiece, and ultraviolet light must be avoided from irradiating areas other than the glue line area. Therefore, the positions that do not require light transmission and pressing are roughened and contoured and sunken. Specific embodiment two:

[0027] Reference Figure 1 , an automatic discharging device is installed on the ultraviolet lamp 2. In this way, after the workpiece is cured by the ultraviolet curing lamp group, the workpiece can be automatically driven to be discharged. The staff does not need to manually assist the workpiece inside the device to discharge the material, thereby avoiding the staff from being irradiated by the ultraviolet curing lamp group, thereby avoiding the ultraviolet curing lamp group causing damage to the staff's skin.

[0028] In summary:

[0029] 1. The cured area profiled transparent glass 3 is used to complete the UV glue pressing of the MEA membrane electrode at 3 points on the cured area profiled transparent glass. The UV glue is flattened. Here, there are high requirements for the strength and flatness of the pressed workpiece, and it is necessary to avoid ultraviolet light irradiation to places other than the glue line area. Therefore, the rough surface processing and profile sinking treatment are performed on the positions that do not require light transmission and pressing;

[0030] 2. The up-and-down floating mechanism 4 is used to ensure that the entire pressing surface of the glass and the workpiece are in full contact with each other when the cylinder is extended and pressed, without any angle, and to prevent the glass from being broken by excessive pressure.

[0031] 3. The pressing position adjustment mechanism 5 is used to adjust the pressing position of the entire glass pressing plate so that the light-transmitting pressing position can be aligned with the UV glue line position of the single cell, thereby ensuring the pressing and curing accuracy;

[0032] 4. The above structure is adopted to realize a UV glue pressing and ultraviolet light curing mechanism specially used for UV glue curing in single-cell production lines. Compared with traditional manual production, it greatly improves production efficiency and single-cell product qualification rate. The overall design structure is simple and easy to adjust, with low machining and assembly requirements, saving costs and reducing labor intensity.
