Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0024] Glossary Defect detection: Detecting surface defects such as scratches, dents, bumps, material impurities, corrosion, and coating peeling.
[0025] 3D inspection: accuracy of flow channel dimensions, such as depth, width, and spacing; flatness of bipolar plate sealing surfaces, etc.
[0026] Research has revealed that existing technologies using adsorption-type flipping components are only suitable for vacuum adsorption of flat membrane electrodes, and are not suitable for bipolar plates with pores. In addition, the flipping of the membrane electrodes in the aforementioned membrane electrode detection equipment requires two spaced conveyor belts to coordinate the surface change, which requires a large installation space. Furthermore, after long-term operation, the back-and-forth placement of the membrane electrodes on the two conveyor belts will increase the risk of cross-contamination of the workpieces.
[0027] Based on the above research, the present disclosure provides a flipping and loading mechanism for membrane electrodes or bipolar plates and a detection device using the same, which includes a loading component, two flipping mechanisms, and a subsequent defect detection component or 3D detection component. It can simultaneously adapt to defect detection of membrane electrodes and bipolar plates, as well as 3D detection of bipolar plates. Furthermore, it only requires one loading component, has a small installation space, and there is no risk of cross-contamination of the workpiece under test.
[0028] The shortcomings of the above solutions are the result of the inventors' practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the inventors to this disclosure.
[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0030] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0031] refer to Figure 1At least one embodiment illustrates a flipping and transfer mechanism for a membrane electrode or bipolar plate, comprising: a transfer assembly 1 for moving one of the membrane electrode or bipolar plate along the Y-axis; two flipping mechanisms 100, mirror-located on both sides of the transfer assembly 1, each including a flipping assembly 2 for flipping one of the membrane electrode or bipolar plate; a lifting assembly 3, the flipping assembly 2 connected to the lifting assembly 3 for driving the flipping assembly 2 to move along the Z-axis; and a translation assembly 4, the lifting assembly 3 connected to the translation assembly 4 for driving the lifting assembly 3 and the flipping assembly 2 to move along the X-axis.
[0032] First, the mounting platform 200 is set as the base. In this embodiment and the embodiments below, the flipping and loading mechanism and the detection device for the membrane electrode or bipolar plate are all mounted on the mounting platform 200. In some embodiments, for ease of explanation, the membrane electrode or bipolar plate can be referred to as the workpiece 400 to be tested.
[0033] In summary, there is one transfer assembly 1 specifically designed for transferring the workpiece 400 under test. Both membrane electrodes and bipolar plates can be used, with adjustments made according to actual needs. Two flipping assemblies 2 are positioned mirror images of the transfer assembly 1 on either side, minimizing the usable area of the mounting platform 200. The two flipping assemblies 2 operate synchronously, jointly flipping the workpiece 400 under test. Two lifting assemblies 3 operate synchronously, causing the flipping assembly 2 to move along the Z-axis. The main purpose of this Z-axis displacement is to move the flipping assembly 2 away from the transfer assembly 1 in the Z-axis before it flips, preventing interference between the workpiece 400 and the transfer assembly 1 during the flipping action. Two translational assemblies 4 are used to move the lifting assembly 3 and the flipping assembly 2 along the X-axis. Their main purpose is to synchronously adjust the distance between the two flipping assemblies 2. This allows them to approach the workpiece 400 simultaneously for subsequent flipping operations. Furthermore, adjusting the distance between the two flipping assemblies 2 in advance allows them to accommodate workpieces 400 of different sizes.
[0034] In short, firstly, the movable distance between the two translation components 4 is pre-set according to the size of the workpiece 400 to be tested. The translation components 4 drive the flipping components 2 on the lifting components 3 to approach the workpiece 400 to be tested, and the flipping components 2 simultaneously fix the two sides of the workpiece 400 to be tested. Then, the two lifting components 3 move synchronously, driving the two flipping components 2 away from the transfer components 1; in a position that does not interfere with the transfer components 1, the flipping components 2 flip the workpiece 400 to be tested by 180°. Then, the two lifting components 3 move synchronously again, driving the two flipping components 2 to approach the transfer components 1, the flipping components 2 stop fixing the two sides of the workpiece 400 to be tested, so that the workpiece 400 to be tested is placed on the transfer components 1, the translation components 4 retract, and the transfer components 1 transfer the workpiece 400 to be tested.
[0035] refer to Figure 2 In some embodiments, the transfer assembly 1 includes: a carrier plate 11 for placing one of the membrane electrode or bipolar plate; a transfer connecting stage 12, to which the carrier plate 11 is connected; and a transfer slide module 13, to which the transfer connecting stage 12 is connected, and which drives the transfer connecting stage 12 to move along the Y-axis.
[0036] In short, the transfer slide module 13 provides the power for Y-axis movement and is positioned on the mounting platform 200. The carrier plate 11 is used to hold the workpiece 400 to be tested and is fixedly connected to the transfer connecting stage 12. The transfer connecting stage 12 can be, but is not limited to, a rectangular shape, and its specific height is adjusted according to the height of the flipping assembly 2 from the mounting platform 200, allowing the flipping assembly 2 to operate on the workpiece 400 to be tested on the carrier plate 11.
[0037] refer to Figure 1 , Figure 2 In some embodiments, the carrier plate 11 includes a plurality of positioning pins 111 for positioning one of the membrane electrode or bipolar plate. The positions of the positioning pins 111 are set according to the holes on the membrane electrode or bipolar plate, with the aim of accurately placing the membrane electrode or bipolar plate on the carrier plate 11. Figure 1 , Figure 2 As shown, there are 4 locating pins 111, which are used for positioning based on 2 of the 4 arc-shaped holes on the workpiece 400 to be tested.
[0038] refer to Figure 3 In some embodiments, the flipping assembly 2 includes: a cylinder gripper 21 for gripping one of the membrane electrode or bipolar plate; a first hollow rotating platform 22 for driving the cylinder gripper 21 to flip; and a first connecting plate 23 connected between the cylinder gripper 21 and the first hollow rotating platform 22.
[0039] In short, the movable distance between the two translation components 4 is pre-set according to the size of the workpiece 400 to be tested. The translation component 4 first moves the cylinder gripper 21 closer to the workpiece 400 to be tested, and the cylinder gripper 21 clamps and fixes the workpiece 400 to be tested. Then, the lifting component 3 raises the entire flipping component 2 to a height that does not interfere with the transfer component 1. The first hollow rotating platform 22 drives the cylinder gripper 21 to rotate 180° through the first connecting plate 23, so that the workpiece 400 to be tested is flipped. Then, the lifting component 3 lowers the entire flipping component 2, the cylinder gripper 21 releases the workpiece 400 to be tested, and places it on the transfer component 1. The translation component 4 retracts, and the transfer component 1 performs the transfer.
[0040] refer to Figure 3 In some embodiments, the lifting assembly 3 includes: a second connecting plate 31, one end of which is connected to the flipping assembly 2; and a first sliding module 32, which is connected to the other end of the second connecting plate 31 and is used to drive the second connecting plate 31 to perform Z-axis displacement.
[0041] In short, the movable distance between the two translation components 4 is pre-set according to the size of the workpiece 400 to be tested. The translation component 4 first moves the flipping component 2 closer to the workpiece 400 to be tested. After the flipping component 2 clamps and fixes the workpiece 400 to be tested, the first slide module 32 drives the entire flipping component 2 to a height that does not interfere with the transfer component 1 through the second connecting plate 31. The flipping component 2 flips the workpiece 400 to be tested. Then, the first slide module 32 drives the entire flipping component 2 to descend through the second connecting plate 31. The flipping component 2 stops fixing the workpiece 400 to be tested, so that the workpiece 400 to be tested is placed behind the transfer component 1. The translation component 4 retracts, and the transfer component 1 performs the transfer.
[0042] refer to Figure 3 In some embodiments, the translation component 4 includes: a third connecting plate 41, one end of which is connected to the lifting component 3; and a second sliding module 42, which is connected to the other end of the third connecting plate 41 and is used to drive the third connecting plate 41 to perform X-axis displacement.
[0043] In short, based on the size of the workpiece 400 to be tested, the movable distance between the third connecting plates 41 on the two translation components 4 is pre-set to reduce unnecessary X-axis displacement of the second slide module 42. The second slide module 42 drives the lifting component 3 to move closer to the workpiece 400 via the third connecting plate 41, so that the flipping component 2 on the lifting component 3 approaches the workpiece 400. After the flipping component 2 clamps and fixes the workpiece 400, the lifting component 3 drives the entire flipping component 2 to a height that does not interfere with the transfer component 1. The flipping component 2 flips the workpiece 400, and then the lifting component 3 drives the entire flipping component 2 to descend. The flipping component 2 stops fixing the workpiece 400, so that the workpiece 400 is placed on the transfer component 1, the translation component 4 retracts, and the transfer component 1 performs the transfer operation.
[0044] refer to Figure 4 At least one embodiment illustrates a detection device, comprising: As described above, the overturning and transfer mechanism includes a defect detection component 5, which comprises: a defect detection camera 51 for detecting defects in one of the membrane electrode or bipolar plate; a third slide module 52 for driving the defect detection camera 51 to move in the X-axis; and a fourth connecting plate 53, through which the defect detection camera 51 is connected to the third slide module 52.
[0045] The detection equipment in this embodiment is mainly used to detect surface defects of membrane electrodes or bipolar plates, such as scratches, pits, protrusions, material impurities, corrosion, and coating peeling. The transfer assembly 1 transfers the workpiece 400 to be tested, or the flipped workpiece 400, to the defect detection assembly 5. The third slide module 52 drives the defect detection camera 51 to move above the workpiece 400 for defect detection via the fourth connecting plate 53.
[0046] refer to Figure 5 , Figure 6 In some embodiments, the defect detection component 5 further includes: a defect detection camera light bar 54, which is used to assist the defect detection camera 51 in lighting; and a fifth connecting plate 55, which connects the fourth connecting plate 53 and the light bar 54.
[0047] The strip light 54 of the defect detection camera is used to assist the defect detection camera 51 in lighting. In order to improve the lighting effect, the fifth connecting plate 55 may, but is not limited to, have multiple strip light mounting holes 551, so that the installation angle of the strip light 54 of the defect detection camera can be adjusted according to the strip light mounting holes 551 during installation.
[0048] refer to Figure 9 In some embodiments, a protective rack 300 is also configured.
[0049] refer to Figure 7 At least one embodiment illustrates a detection device, including: the flipping and loading mechanism as described above; a 3D detection component 6, which includes: a laser profile tester 61, the laser profile tester 61 being used to perform 3D detection on a bipolar plate; and a fourth slide module 62, the fourth slide module 62 being used to drive the laser profile tester 61 to move along the X-axis.
[0050] The detection equipment in this embodiment is mainly used for 3D detection of bipolar plates, such as the accuracy of flow channel dimensions, including depth, width, and spacing; and the flatness of the bipolar plate sealing surface. The fourth slide module 62 drives the laser contour tester 61 to translate along the X-axis and move it above the workpiece 400 to be tested for 3D detection.
[0051] refer to Figure 7 , Figure 8 In some embodiments, the 3D detection component 6 further includes: a fifth slide module 63, which drives the laser profile tester 61 to move along the Z-axis; a second hollow rotary platform 64, which drives the laser profile tester 61 to rotate; a sixth connecting plate 65, which connects the fifth slide module 63 and the second hollow rotary platform 64; and a seventh connecting plate 66, which connects the second hollow rotary platform 64 and the laser profile tester 61.
[0052] In short, to allow the laser profile tester 61 to perform its inspection work more effectively, the fifth slide module 63 can drive the laser profile tester 61 to move up and down, and the second hollow rotary platform 64 can drive the laser profile tester 61 to rotate. The sixth connecting plate 65 and the seventh connecting plate 66 can be made of sheet metal or other materials, and their shapes are not specifically limited here, as long as they do not interfere with the operation of the laser profile tester 61.
[0053] refer to Figure 9 In some embodiments, a protective rack 300 is also configured.

[0057] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein.

Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0061] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0062] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
