Description

Technical Field

[0001] This utility model relates to the field of fuel cell technology, specifically to a fuel cell composite bipolar plate sealing strip base coating device. Background Technology

In traditional sealing processes, the sealing strip is directly applied to the surface of the bipolar plate, which can easily lead to insufficient adhesion and incomplete sealing. To improve the adhesion of the sealing strip, a primer treatment is required before applying the sealing strip to enhance adhesion and sealing performance. Primer application is usually done manually or using simple mechanical methods to treat the bipolar plate surface, which can easily result in uneven adhesive application and low efficiency.

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-7 As shown, a fuel cell composite bipolar plate sealing strip base coating device includes a base 1, a turntable 2 rotatably mounted on the base 1, a plurality of support plates 3 for placing bipolar plates are provided on the edge of the turntable 2, a limiting component for positioning the bipolar plates is provided on the support plate 3, the limiting component includes a plurality of fixing pieces 4 located on the support plate 3, and an adhesive coating mechanism is provided above the support plate 3.

[0023] In the above specific technical solution, the turntable 2 is equipped with multiple support plates 3. The operator first places the bipolar plate on the support plate 3 at the loading station. The turntable 2 rotates to move the bipolar plate to the bottom of the gluing mechanism. The gluing mechanism applies a base coat to the overflow groove of the bipolar plate. Then the turntable 2 continues to rotate, moving the bipolar plate with the base coat to the unloading station for easy unloading by the operator. Preferably, four support plates 3 are provided, corresponding to the loading station, intermediate station, spraying station and unloading station respectively. During the gluing process of the gluing mechanism, the operator places the bipolar plate on the support plate 3 located at the loading station. After the bipolar plate is coated with glue, the bipolar plate at the intermediate station moves to the bottom of the gluing mechanism, ensuring the continuity of the gluing and improving the efficiency of the gluing.

[0024] The adhesive application mechanism includes a glue bottle 5, with a dispensing nozzle 6 at the bottom of the bottle 5 inserted into a through hole on a support plate 7. A valve body 8 is located below the support plate 7, and a liquid channel 9 communicating with the interior of the glue bottle 5 is located within the valve body 8. An adhesive application nozzle 10 is located at the bottom of the liquid channel 9, and an air inlet pipe 11 is located at the top of the glue bottle 5. When adhesive application is required, gas is injected into the glue bottle 5 through the air inlet pipe 11, causing the base adhesive inside the bottle 5 to be sprayed out through the adhesive application nozzle 10 and applied into the overflow tank.

[0025] The support plate 7 is also provided with a fixing block 12. The fixing block 12 has a through groove communicating with the liquid channel 9. A valve needle 13 is installed in the through groove. The top of the valve needle 13 is threaded. The top of the fixing block 12 is provided with a limiting ring 14 that is threadedly connected to the valve needle 13. The top of the valve needle 13 is provided with a cap 15. Tightening the valve needle 13 will cause it to move downwards and block the liquid channel 9. Tightening the valve needle 13 will cause it to move downwards. When the valve needle 13 blocks the bottom of the liquid channel 9, the base adhesive will no longer flow out, preventing the base adhesive from leaking and wasting raw materials when not in use.

[0026] The bottom of the valve needle 13 is provided with a sealing ring 16, which plays a sealing role when the valve needle 13 blocks the liquid channel 9.

[0027] The support plate 7 is fixedly installed on the movable plate 17. The movable plate 17 is provided with a slider 18. The slider 18 is raised and lowered by a lifting mechanism 19. The lifting mechanism 19 is installed on a first moving mechanism 20. The first moving mechanism 20 is installed on a second moving mechanism 21. The first moving mechanism 20 and the second moving mechanism 21 drive the lifting mechanism 19 to move horizontally along a specified line.

[0028] In the above specific technical solution, the lifting mechanism 19 is equipped with a motor, which drives the sprocket to rotate. The sprocket is connected to the chain, and the slider 18 is connected to the chain. The movement of the chain realizes the movement of the moving plate 17. The downward movement of the glue bottle 5 realizes close-range spraying of the base glue, which is beneficial to improving the spraying effect. It is worth noting that the structural principle of the first moving mechanism 20 and the second moving mechanism 21 is the same as that of the lifting mechanism 19. The first moving mechanism 20 and the second moving mechanism 21 drive the glue bottle 5 to move in the horizontal direction, which can realize the movement of the glue bottle 5 along the trajectory of the overflow groove.

[0029] The support plate 3 is provided with positioning holes 22 on both the front and rear sides, and the fixing plate 4 is provided with a waist-shaped hole 23. The fastening bolt 24 passes through the waist-shaped hole 23 and is threadedly connected to the positioning hole 22. The support plate 3 is provided with a positioning block 25 on the left or right side. The position of the fixing plate 4 is adjusted according to the size of the bipolar plate. Preferably, the position of the front fixing plate 4 can be fixed. After the bipolar plate is placed on the support plate 3, the two sides of the bipolar plate abut against the positioning block 25 and the front fixing plate 4 respectively. Then, the rear fixing plate 4 is adjusted so that the fixing plate 4 abuts against the bipolar plate. Then, the fixing plate 4 is fixed by tightening the fastening bolt 24, thereby achieving accurate positioning of the bipolar plate, which is beneficial to improving the spraying accuracy and is convenient for positioning.

[0030] The base 1 is equipped with a rotary motor, and the output end of the rotary motor is connected to the turntable 2.

[0031] The support plate 3 is made of iron, and several circular magnetic sheets are placed on the edge of the bipolar plate. The circular magnetic sheets have an adsorption property with the support plate 3, which can play a certain role in fixing the bipolar plate.

The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
