[0034] Specifically, in this embodiment, the bipolar plate detection equipment also includes a workbench 10 including a cabinet and a work platform arranged on the upper end surface of the cabinet, and the detection mechanism 30, the transfer mechanism 40, the first waste box 51 and the qualified material box 52 are all arranged on the work platform.

[0035] like Figure 5As shown, the third detection member 33 includes a frame 331, a detection turntable 332, a detection assembly 333 and a driving member. The frame 331 is arranged on the workbench 10. The frame 331 has an initial station, a first detection station, a second detection station and a defect detection station. The detection turntable 332 is placed horizontally and rotatably around its vertical axis. The upper surface of the detection turntable 332 is provided with a bipolar plate fixture placement position 3321. The detection assembly 333 includes a first flow channel detection member, a second flow channel detection member and a defect detection member arranged at intervals around the vertical axis of the detection turntable 332. The first detection station corresponds to the first flow channel detection member, the second detection station corresponds to the second flow channel detection member, and the defect detection station corresponds to the defect detection member. The fourth transfer member 44 is arranged between the defect detection station and the first waste box 51 and between the initial station and the qualified material box 52. The driving member is arranged on the workbench 10 and is drivingly connected to the detection turntable 332. After the second inspection member 32 completes the inspection of the bipolar plate, the third transport member 43 is used to transport the bipolar plate on the second inspection member 32 to the initial station, and the driving member is used to intermittently rotate the inspection turn plate 332 so that the bipolar plate passes through the initial station, the first inspection station, the second inspection station and the defect inspection station in sequence, so that the bipolar plate is inspected by the first flow channel inspection member, the second flow channel inspection member and the defect inspection member in sequence. After the third inspection member 33 completes the inspection of the bipolar plate, the fourth transport member 44 is used to transport the bipolar plate on the initial station to the first waste box 51 or the qualified box 52 according to the inspection result of the inspection mechanism 30.

[0036] Specifically, the first flow channel detection component detects the depth and burr condition of the transverse flow channel of the bipolar plate, the second flow channel detection component 314 detects the depth and burr condition of the longitudinal flow channel of the bipolar plate, and the defect detection component detects flow channel defects of the bipolar plate.

After the second inspection member 32 completes the inspection of the bipolar plate, the third transport member 43 is used to transport the bipolar plate on the second inspection member 32 to the initial station, and the driving member is used to intermittently rotate the inspection rotating plate 332, so as to sequentially use the first flow channel inspection member, the second flow channel inspection member and the defect inspection member to inspect the front of the bipolar plate. If the front inspection of the bipolar plate is unqualified, the fourth transport member 44 transports the bipolar plate from the defect inspection station to the first waste material box 51. If the front inspection of the bipolar plate is qualified, the driving member is used to continue to rotate the inspection rotating plate 332, and the bipolar plate is transferred to the initial station, and then the first flow channel inspection member, the second flow channel inspection member and the defect inspection member are used to inspect the front of the bipolar plate. The bipolar plate at the initial station is turned over by using the turning member 334, and the detection turn plate 332 is rotated intermittently by using the driving member again, so as to detect the back side of the bipolar plate in turn by using the first flow channel detection member, the second flow channel detection member and the defect detection member. If the back side of the bipolar plate fails the detection, the fourth transfer member 44 transfers the bipolar plate from the defect detection station to the first waste box 51. If the back side of the bipolar plate passes the detection, the driving member continues to rotate the detection turn plate 332, the bipolar plate is transferred to the initial station, and the fourth transfer member 44 transfers the bipolar plate from the initial station to the qualified material box 52.

The third transport member 43 can transfer the bipolar plate between the clamp and the initial station. The flipping driving member is arranged on the workbench 10 and is connected to the clamp. If the front detection of the bipolar plate is qualified, the driving member continues to rotate the detection rotating plate 332, the bipolar plate is transferred to the initial station, the third transport member 43 transfers the bipolar plate on the initial station to the clamp, and the flipping driving member drives the clamp to rotate 180 degrees to flip the bipolar plate horizontally 180 degrees, and then the third transport member 43 is used to transfer the bipolar plate on the clamp to the initial station again.

The flipping driving member is arranged on the side of the support plate facing the third detection member 33, the mounting plate is arranged on the side of the flipping driving member away from the support plate, and the clamp is arranged on the side of the support plate facing the third detection member 33.

[0040] Specifically, the detection turntable 332 adopts a cross-plate structure, and the four ends of the upper end surface of the cross-plate are provided with bipolar plate placement jigs. By rotating the detection turntable 332, the bipolar plate placement jig can be rotated to the initial position, the first detection position, the second detection position and the defect detection position respectively.

The fourth transport part 44 works according to the analysis result of the defect analysis part on the picture taken by the detection camera. If the first flow channel detection part, the second flow channel detection part and the defect detection part detect that the front or back of the bipolar plate is unqualified, the fourth transport part 44 will transfer the bipolar plate from the defect detection station to the first waste box 51, and the detection camera is used to obtain the picture of the flow channel of the bipolar plate, and the defect analysis part is used to analyze the captured picture to detect the flow channel defects of the bipolar plate.

[0042] The initial station, the first inspection station, the second inspection station and the defect inspection station are arranged at equal intervals in the circumferential direction around the vertical axis of the inspection rotating plate 332.
