Description

Technical Field

[0001] This invention relates to the field of bipolar plate processing technology, and more specifically to a hydrophobic treatment and storage device for fuel cell bipolar plates. Background Technology

[0002] Fuel cell bipolar plates can be classified into graphite bipolar plates, metal bipolar plates, and composite material bipolar plates according to different materials. Currently, graphite bipolar plates are the most commonly used bipolar plates. They have advantages such as high electrical conductivity, chemical stability, thermal stability, corrosion resistance, and low density, which give them unique advantages in manufacturing bipolar plates. After the graphite bipolar plates are molded and impregnated, their surfaces are treated with hydrophobicity. The existing hydrophobicity treatment method is to stack the graphite bipolar plates on a storage rack, which is very inconvenient to pick up and put away, and the hydrophobicity treatment of graphite bipolar plates is not comprehensive.

[0005] The technical solution of the present invention is as follows:

A top frame is slidably disposed on the base frame. The top frame includes a top frame and slide rods fixedly disposed at the four corners of the top frame. Several sets of clamping components a are disposed on the front and rear sides of the base frame. Several sets of clamping components b are disposed on the front and rear sides of the top frame. Several sets of hydrophobic treatment components are disposed on the top of the top frame. A lifting component is disposed above the top frame. An adjusting component is also disposed on the top frame. The clamping components a and b are used to clamp the bottom and top of the bipolar plates, respectively. The adjusting component is used to drive the clamping components b to move left and right. The lifting component is used to adjust the height of the clamping components b.

Detailed Implementation

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 6 As shown, a hydrophobic treatment and storage device for fuel cell bipolar plates includes a base frame 1 and support legs 101 fixedly disposed at the four corners of the base frame 1. A top frame 11 is slidably disposed on the base frame 1. The top frame 11 includes a top frame 102 and slide rods 103 fixedly disposed at the four corners of the top frame 102. Several sets of clamping components a2 are disposed on the front and rear sides of the base frame 1, and several sets of clamping components b3 are disposed on the front and rear sides of the top frame 11. Several sets of hydrophobic treatment components 4 are disposed on the top of the top frame 11. A lifting component 5 is disposed above the top frame 11, and an adjustment component 6 is also disposed on the top frame 11. The clamping components a2 and b3 are used to clamp the bottom and top of the bipolar plate 7, respectively. The adjustment component 6 is used to drive the clamping components b3 to move left and right. The lifting component 5 is used to adjust the height of the clamping components b3. The hydrophobic treatment components 4 are used to perform hydrophobic treatment on the front and back sides of the bipolar plate 7.

[0032] like Figure 3 As shown, the clamping assembly a2 includes a fixed base 21 fixedly mounted on the base frame 1, a fixed plate a22 hinged to the fixed base 21, support rods a23 fixedly mounted on both sides of the fixed plate a22, a roller seat a24 fixedly mounted on the top of the support rods a23, and rollers a25 rotatably mounted on the roller seat a24. The two sides of the bipolar plate 7 are clamped by the rollers a25.

[0033] like Figure 3 and Figure 5 As shown, the top frame 102 has sliding grooves 12 on both the front and rear sides. The clamping assembly b3 includes a slide seat 31 slidably disposed in the sliding groove 12, a rotating shaft 32 fixedly disposed on the slide seat 31, a fixed plate b33 rotatably disposed on the rotating shaft 32, support rods b34 fixedly disposed on both sides of the fixed plate b33, a roller seat b35 fixedly disposed at the bottom of the support rod b34, and rollers b36 rotatably disposed on the roller seat b35. In use, the operator inserts the bipolar plate 7 into the clamping assembly a2 and the clamping assembly b3. The top of the bipolar plate 7 is between the two rollers b36, and the bottom of the bipolar plate 7 is between the two rollers a25.

[0034] like Figure 2 and Figure 4 As shown, the hydrophobic treatment component 4 includes a water inlet 41 fixedly mounted on the top frame 102, a water cavity 42 opened inside the top frame 102, a flushing pipe 43 fixedly mounted on the top frame 102, and several flushing holes 44 inclinedly opened on the left and right sides of the flushing pipe 43. The water cavity 42 is connected to the water inlet 41, and the flushing pipe 43 is connected to the water cavity 42. In use, the water inlet 41 is connected to the water supply device, the water cavity 42 is filled with water, and then the water is flushed onto the bipolar plate 7 through the flushing holes 44 to perform hydrophobic treatment on the bipolar plate 7. There is no need to remove the bipolar plate 7 for hydrophobic treatment, avoiding damage to the bipolar plate 7 caused by frequent handling. In addition, the several bipolar plates 7 are separated, and there is a rinsing space, which improves the hydrophobic treatment effect of the bipolar plate 7.

[0035] like Figure 1As shown, a fixed frame 8 is fixedly installed on the top of the top frame 102. The top of the fixed frame 8 has a through hole 81. The lifting assembly 5 includes a support frame 51, a motor 52 fixedly installed on the support frame 51, a lead screw a53 driven by the motor 52, and a lead screw nut a54 slidably installed on the lead screw a53. The top of the fixed frame 8 is fixedly connected to the bottom of the lead screw nut a54. The lead screw a53 is rotatably installed in the through hole 81. In use, when the motor 52 is turned on, the motor 52 rotates forward, driving the lead screw a53 to rotate forward, thereby causing the lead screw nut a54 to drive the fixed frame 8 and the top frame 102 to descend. When the motor 52 rotates in reverse, it drives the lead screw a53 to rotate in reverse, thereby causing the lead screw nut a54 to drive the fixed frame 8 and the top frame 102 to rise. This achieves the effect of adjustable height for the clamping assembly b3, allowing the height of the clamping assembly b3 to be adjusted according to the size of the bipolar plate 7, making the storage device more practical.

[0036] like Figure 2 and Figure 3 As shown, the adjustment assembly 6 includes a lead screw b61 rotatably mounted on the front and rear sides of the top frame 102 and several lead screw nuts b62 slidably mounted on the lead screw b61. Each lead screw b61 is fixedly equipped with a pulley 63, and a belt 64 connects the two pulleys 63. A handwheel 65 is also fixedly mounted on the lead screw b61 located in front of the top frame 102. The lead screw nuts b62 are fixedly connected to the slide block 31. The lead screw nuts b62 are evenly spaced. In use, when the operator rotates the handwheel 65 clockwise, the lead screw b61 rotates clockwise, causing the lead screw nuts b62 to move the slide block 31 to the left within the slide groove 12, causing the bipolar plate 7 to tilt to the left. When the operator reverses the handwheel 65, the lead screw b61 rotates counterclockwise, causing the lead screw nuts b62 to move the slide block 31 to the right within the slide groove 12, causing the bipolar plate 7 to tilt to the right. This method allows the flushing holes 44 to rinse both sides of the bipolar plate 7 more thoroughly, resulting in better hydrophobic treatment.

[0037] like Figure 1 As shown, a drainage plate 9 is fixedly installed inside the bottom frame 1, and the drainage plate 9 is designed with a structure that is high in the middle and low on both sides. By setting the drainage plate 9 with a high middle and low on both sides, the sewage after rinsing can be discharged from both sides of the drainage plate 9, thus preventing sewage from accumulating in the storage device.

[0038] like Figure 1 As shown, the slide bar 103 is slidably disposed within the support leg 101.

[0039] Example 2

[0040] like Figure 2As shown, the components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as those in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that buffer pads 82 are fixedly provided between the two support rods a23 and between the two support rods b34.

[0041] Here, in this embodiment, by setting buffer pads 82 between the two support rods a23 and between the two support rods b34, it can play a protective role on the one hand, and on the other hand, it can buffer the bipolar plate 7 when the clamping component b is pressed down, so as to prevent the bipolar plate 7 from being deformed due to compression.

[0042] Work process

[0043] First, the operator inserts the bipolar plate 7 into the clamping components a2 and b3. Based on the size of the bipolar plate 7, the height of the clamping component b3 is adjusted by the lifting component 5. Once the height is appropriate, the clamping components a2 and b3 clamp the bipolar plate 7, thus beginning the hydrophobic treatment of the bipolar plate 7. During the hydrophobic treatment of the bipolar plate 7 through the flushing holes 44, the operator rotates the handwheel 65 clockwise or counterclockwise. Driven by the lead screw nut b62, the clamping component b3 tilts the bipolar plate 7 to the left or right, allowing the bipolar plate 7 to fully contact the water. This ensures that the flushing holes 44 clean both sides of the bipolar plate 7 more thoroughly, resulting in a better hydrophobic treatment effect.
