Description

TECHNICAL FIELD

[0001] The utility model relates to new energy production technical field especially relates to a high accuracy bipolar plate adsorption platform with profiling design. BACKGROUND

[0002] In the field of hydrogen energy stack production, accurate positioning and flat adsorption of bipolar plates are crucial for the performance of the stack. Currently, the common bipolar plate adsorption platform tooling mainly has the following forms. One is to use a simple mechanical support structure to fix the bipolar plate through clamps and other methods. Another is a platform tooling with certain adsorption function.

[0003] In the production process of hydrogen energy stacks, accurate positioning and flat adsorption of bipolar plates are crucial. However, in the prior art, many platform toolings have obvious shortcomings. On the one hand, a large number of platform toolings do not have vacuum adsorption function, which makes the bipolar plate rely only on simple physical support when placed on the platform, lacking effective adsorption force to ensure the stability of its position. In the production process, due to slight external interference or uneven distribution of its own gravity, the bipolar plate is prone to move, resulting in inaccurate positioning and affecting the assembly quality of the entire stack. On the other hand, some platform toolings may have certain adsorption function, but do not have profiling suction holes and glue avoidance grooves. Without profiling suction holes, targeted adsorption according to the specific shape and size of the bipolar plate cannot be achieved, making it difficult to achieve comprehensive and uniform adsorption of the bipolar plate, resulting in uneven adsorption. The lack of glue avoidance grooves will damage the glue line on the bipolar plate during adsorption, affecting the integrity and functionality of the glue line. At the same time, due to uneven adsorption, the bipolar plate is prone to angle warping. This angle warping not only affects the appearance quality of the bipolar plate, but also seriously affects its performance in the stack, reducing the reliability and service life of the stack, so a high-precision bipolar plate adsorption platform with profiling design is needed to solve the above problems.

[0027] The middle of the top of suction plate cover plate 1 is evenly distributed with suction hole 5, the diameter of suction hole 5 is 1mm, and the spacing between suction hole 5 on the top of suction plate cover plate 1 is equal.

[0028] Suction plate cover plate 1 is used to support and position the bipolar plate, and has positioning pin hole, which can be inserted with positioning dowel 3 for positioning the bipolar plate, and has 1mm diameter suction hole 5, which is evenly distributed according to certain spacing and trajectory profiling, and is used to adsorb the bipolar plate.

[0029] The front surface of suction plate bottom plate 2 is provided with pipe thread interface 7, the pipe thread interface 7 is matched with one end of the inner side of negative pressure air pipe joint 4, and the front surface of suction plate bottom plate 2 has four groups of negative pressure air pipe joints 4.

[0030] Suction plate bottom plate 2 is used to be locked with suction plate cover plate 1, and after being connected with negative pressure pipeline, can provide continuous and stable negative pressure suction force on the surface of suction plate cover plate 1 to adsorb the bipolar plate.

[0031] The arrangement angle of positioning dowel 3 on one side of the top of suction plate cover plate 1 is 90 DEG, forming a right-angled edge positioning, and the positioning dowel is used to form a right-angled edge positioning to provide accurate positioning for the bipolar plate.

[0034] Reference Figs. 1-6The suction holes 5 are designed on the suction plate cover plate 1 according to the shape of the bipolar plate to ensure that the bipolar plate can be uniformly adsorbed on the suction plate, and the suction plate cover plate 1 has high planeness processing requirements, which solves the problem of the warped edge of the bipolar plate.

[0035] The design of the suction plate bottom plate 2 is that there is a certain depth groove on it, which is locked together with the suction plate cover plate 1, and then connected with the negative pressure pipeline. The air in the groove of the suction plate bottom plate 2 is continuously sucked away, and the outside air can only be supplemented through the 1mm suction hole of the suction plate cover plate 1.

The connection part between the negative pressure air pipe joint 4 and the negative pressure pipeline is sealed with a sealing gasket to ensure that there is no air leakage phenomenon in the working process. The sealing gasket is made of corrosion-resistant and high-temperature-resistant materials, which can adapt to different working environments. The outer surface of the negative pressure air pipe joint 4 is provided with anti-slip lines to facilitate the installation and disassembly of the operator.

[0042] 2、In the equipment, the suction plate bottom plate 2 is designed to have a certain depth of groove, and after being locked with the suction plate cover plate 1, the negative pressure pipeline is connected, the air in the groove of the suction plate bottom plate 2 is continuously sucked away, and the external air can only be supplemented through the 1mm suction hole of the suction plate cover plate 1, and since the suction hole 5 is small, the speed of the supplemented air is far less than the speed of the negative pressure suction, so that a continuous and stable negative pressure suction force is formed on the surface of the suction plate cover plate 1, and the bipolar plate adsorption platform fully considers the principle of human engineering in the design process, is convenient and fast to operate, and can improve the production efficiency. The cooperation precision between the various components of the adsorption platform is high, so that stable and reliable operation can be realized in the working process.
