Technical Field

[0001] This invention relates to the field of electrode plate production technology, specifically to a fully automated electrode plate testing method and system. Background Technology

[0002] With the development of new energy vehicles, fuel cells are being used more and more widely. Fuel cells contain bipolar plates, which are the main functional components for gas distribution, heat conduction, and electrical conduction in fuel cells. They are important components of hydrogen fuel cells and also constitute a major part of the stack mass.

[0003] Chinese Patent No. 202211704005.3 discloses an airtightness testing mechanism, comprising a first conveying track, a second conveying track, an airtightness testing device, two first unloading cassettes, two first transfer devices, and a first positioning device.

[0004] During the production of bipolar plates in fuel cells, their thickness and resistance need to be tested. Current testing methods are mostly manual or semi-automatic, resulting in low testing efficiency and wasted manpower. Therefore, there is an urgent need to design a fully automated bipolar plate testing method and system to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automated electrode plate detection method and system to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated electrode plate detection system includes a chassis. The bottom inner wall of the chassis is sequentially equipped with a feeding mechanism, a dust removal mechanism, a detection mechanism, and a discharging mechanism. The detection mechanism includes a second servo stage, inside which is a motion frame. A thickness detection probe is fixed inside the motion frame. A resistance detection assembly is located on one side of the motion frame. The resistance detection assembly includes an electric telescopic rod. A four-electrode probe is fixed to the output end of the electric telescopic rod. A displacement sensor is fixed to the outer wall of one side of the electric telescopic rod, with its detection end fixed to the four-electrode probe. A connecting groove is provided on the outer wall of one side of the motion frame. A connecting block is fixed to the outer wall of one side of the electric telescopic rod, located inside the connecting groove. A pressure sensor is fixed to the top inner wall of the connecting groove, located at the top of the connecting block. A control box is located on the outer wall of one side of the chassis. The pressure sensor, displacement sensor, and thickness detection probe are electrically connected to the control box via wires. A guide groove is provided on the bottom outer wall of the connecting block, with a guide post fixed to the inner bottom wall of the connecting groove. The guide post is movably inserted into the guide groove.

[0007] Furthermore, the feeding mechanism includes a servo table one, and a pole plate body one and a pole plate body two are provided on the top of the servo table one. A robot arm three is fixed on one inner wall of the chassis, and the robot arm three is located on the top of the servo table one.

[0008] Furthermore, the unloading mechanism includes a servo table three, and a bearing mechanism one and a bearing mechanism two are provided on the top of the servo table three. A printing and labeling device is fixed on one side inner wall of the chassis. The printing and labeling device is adapted to the bearing mechanism one. A robotic arm one is fixed on one side inner wall of the chassis. The robotic arm one is located on the top of the bearing mechanism two.

[0009] Furthermore, a second robotic arm is fixed to one inner wall of the chassis, and the second robotic arm is located between the first robotic arm and the third robotic arm. A first ranging sensor and a second ranging sensor are fixed to one outer wall of the first robotic arm and the second robotic arm, respectively. The first ranging sensor and the second ranging sensor are electrically connected to the control box.

[0010] Furthermore, a protective sleeve is fitted around the four-electrode probe, and an installation groove is provided on the bottom outer wall of the protective sleeve. A fixing ring is fixed on the inner wall of the installation groove, and bristles are fixed on the inner wall of the fixing ring. A detection electrode is provided at the bottom of the four-electrode probe, and the detection electrode is located at the top of the bristles. A stop block is fixed on the outer wall of the four-electrode probe.

[0011] Furthermore, the outer wall of the four-electrode probe is integrally formed with a retaining ring, and a spring is sleeved on the outside of the four-electrode probe. The spring is located between the retaining ring and the protective sleeve. A guide hole is provided on the bottom outer wall of the protective sleeve. The detection electrode is movably inserted into the guide hole. A support column is fixed on the bottom outer wall of the protective sleeve.

[0012] Furthermore, a support plate is provided on the top of the second servo station, and a placement opening is provided on the top outer wall of the support plate. Both the first electrode body and the second electrode body are adapted to the placement opening.

[0013] A fully automated electrode plate detection method includes the following steps: Feeding steps: Place both electrode body one and electrode body two on servo table one. Use robot arm three to grab electrode body two. When one electrode body two is grabbed, servo table one rises to the height of one electrode body two. After all electrode bodies two are grabbed, servo table one descends and moves electrode body one to the bottom of robot arm three. Dust removal steps: The robotic arm three places the gripped electrode body two or electrode body one inside the dust removal mechanism for dust removal. After the electrode body two or electrode body one has finished dust removal, the robotic arm two places the electrode body two or electrode body one inside the placement opening. Thickness detection steps: The servo stage 2 drives the motion frame to move horizontally and vertically, so that the thickness detection probe can detect the thickness of the electrode body 2. The thickness detection probe transmits the detected thickness data to the control box, and the control box determines whether the thickness is qualified. Resistance testing steps: After the thickness test is completed, the electric telescopic rod drives the four-electrode probe to perform resistance testing on either electrode body 2 or electrode body 1. The four-electrode probe transmits the detected resistance data to the control box, and the control box determines whether the resistance is qualified. Material feeding steps: After the resistance test is completed, the robot arm 1 places the qualified product from electrode body 2 or electrode body 1 onto the bearing mechanism 2. When the robot arm 1 picks up the unqualified product, the control box controls the servo stage 3 to work, so that the servo stage 3 moves the bearing mechanism 1 to the bottom of the robot arm 1, so that the robot arm 1 places the unqualified product onto the bearing mechanism 1. Then, the servo stage 3 drives the bearing mechanism 1 to reset, and the printing and labeling device prints the label of the unqualified product and affixes the label to the upper surface of the unqualified product.

[0014] Furthermore, in the thickness detection step, the control box calculates the difference between the received thickness data and the previously detected thickness data to obtain the thickness compensation parameter. In the resistance step, the control box calculates the stroke based on the compensation parameters and controls the movement of the electric telescopic rod. The displacement sensor measures the stroke of the electric telescopic rod and transmits the measured data to the control box. When the stroke measured by the displacement sensor matches the calculated stroke, the control box controls the electric telescopic rod to stop working. At this time, the four-electrode probe transmits the detected resistance data to the control box.

[0015] Furthermore, in the resistance step, the pressure sensor detects the pressure between the connecting block and the moving frame and transmits the detected pressure data to the control box. When the control box determines that the pressure value is greater than a predetermined value, the control box controls the electric telescopic rod to stop working. At this time, the four-electrode probe transmits the detected resistance data to the control box.

[0016] In the above technical solution, the fully automatic electrode plate detection method and system provided by the present invention have the following beneficial effects: (1) The present invention uses a feeding mechanism, a dust removal mechanism, a detection mechanism and a unloading mechanism to make the entire detection process fully automated, which makes the electrode plate more efficient during detection and not only saves manpower, but also improves the production efficiency of the electrode plate.

[0017] (2) The present invention calculates the difference between plates of different thicknesses as a compensation parameter, so that the resistance detection component can automatically adjust according to the compensation parameter when performing resistance detection on plates of different thicknesses, thereby ensuring the accuracy of the resistance detection parameter. At the same time, the pressure sensor monitors the force during resistance detection, so that the electric telescopic rod stops when the pressure reaches the predetermined value, preventing the phenomenon of impact on the plate when the compensation coefficient is calculated incorrectly, thereby ensuring that the four-electrode probe will not be damaged due to excessive force.

[0018] (3) The present invention installs the plate thickness detection and resistance detection on a servo stage 2, so that the plate thickness and resistance detection can be completed in one process, which not only reduces the cost of equipment, but also saves the time of process conversion.

[0019] (4) The present invention uses the force between the support column and the electrode plate to make the brush bristles rub against the detection electrode, so that the dust on the detection electrode of the four-electrode probe can be cleaned in real time, preventing the accumulation of dust from changing the conductivity of the detection electrode, thereby making the resistance detection of the electrode plate more accurate.

The thickness detection probe 15 has two probes, and the distance between the two thickness detection probes 15 is known. The distance between the electrodes is detected by the two thickness detection probes 15 respectively. Then, the thickness of the electrode is obtained by subtracting the distance between the two thickness detection probes 15 from the distance between the two thickness detection probes 15.

[0031] The present invention provides a fully automatic electrode plate detection method and system. The present invention uses a feeding mechanism 2, a dust removal mechanism 3, a detection mechanism 4 and a discharging mechanism 5 to make the entire detection process fully automated, which makes the electrode plate detection more efficient, saves manpower and improves the production efficiency of electrode plates.

[0032] In another embodiment of the present invention, the feeding mechanism 2 includes a servo table 10. A first electrode plate body 11 and a second electrode plate body 12 are disposed on the top of the servo table 10. The first electrode plate body 11 and the second electrode plate body 12 are two electrode plates of different thicknesses. A third robotic arm 8 is fixed to one inner wall of the chassis 1. The third robotic arm 8 is located on top of the servo table 10. Both the servo table 10 and the third robotic arm 8 are controlled by the control box 9, enabling the third robotic arm 8 to grasp the electrode plates. The servo table 10 and the third robotic arm 8 cooperate with each other. During feeding, both the first electrode plate body 11 and the second electrode plate body 12 are placed on the servo table 10, and the third robotic arm 8 grasps the second electrode plate body 12. When one electrode plate body... After the second electrode body 12 is grasped, the servo stage 10 rises to the height of the second electrode body 12. After the second electrode body 12 is completely grasped, the servo stage 10 descends and moves the first electrode body 11 to the bottom of the third robot arm 8. The unloading mechanism 5 includes a servo stage 3 19. The top of the servo stage 3 19 is equipped with a first bearing mechanism 20 and a second bearing mechanism 21. The first bearing mechanism 20 and the second bearing mechanism 21 stack the defective products and the qualified products, respectively. A printing and labeling device 22 is fixed on one side of the inner wall of the chassis 1. It prints labels containing defective information. The printing and labeling device 22 is adapted to the first bearing mechanism 20. The printing and labeling device 22 affixes the labels to the defective electrode plates. A robotic arm 6 is fixedly positioned at the top of the support mechanism 21. After resistance testing, the robotic arm 6 places the qualified product from the electrode body 212 or electrode body 11 onto the support mechanism 21. When the robotic arm 6 picks up the unqualified product, the control box 9 controls the servo stage 3 19 to move the support mechanism 20 to the bottom of the robotic arm 6, allowing the robotic arm 6 to place the unqualified product onto the support mechanism 20. Then, the servo stage 3 19 drives the support mechanism 20 to reset, and the printing and labeling device 22 prints the label for the unqualified product and affixes it to the upper surface of the unqualified product. A robotic arm 7 is fixed to one inner wall of the chassis 1. Robotic arm 2 7 is located between robotic arm 1 6 and robotic arm 3 8. Distance sensor 1 36 and distance sensor 2 37 are respectively fixed to the outer wall of one side of robotic arm 1 6 and robotic arm 2 7.

Distance sensor 1 36 measures the distance between robotic arm 1 6 and robotic arm 2 7, and distance sensor 2 37 measures the distance between robotic arm 2 7 and robotic arm 3 8.

[0033] Furthermore, a protective sleeve 28 is fitted over the four-electrode probe 24. The protective sleeve 28 is movably fitted over the four-electrode probe 24. A mounting groove 31 is provided on the bottom outer wall of the protective sleeve 28. A fixing ring 32 is fixed on the inner wall of the mounting groove 31. Brush bristles 33 are fixed on the inner wall of the fixing ring 32. A detection electrode 27 is provided at the bottom of the four-electrode probe 24. When the brush bristles 33 move, they can clean the dust on the bottom and around the detection electrode 27. The detection electrode 27 is located on the top of the brush bristles 33. A stop block 35 is fixed on the outer wall of the four-electrode probe 24 to prevent the protective sleeve 28 from detaching from the four-electrode probe 24. A retaining ring 26 is integrally formed on the outer wall of the four-electrode probe 24. A spring 29 is fitted onto the protective sleeve 28, located between the retaining ring 26 and the protective sleeve 28. The spring 29 applies elastic force to the protective sleeve 28. A guide hole 30 is provided on the bottom outer wall of the protective sleeve 28, and the detection electrode 27 is movably inserted into the guide hole 30. A support column 34 is fixed on the bottom outer wall of the protective sleeve 28. When a force is generated between the support column 34 and the electrode plate, the support column 34 drives the protective sleeve 28 to compress the spring 29. At this time, the detection electrode 27 extends out from inside the protective sleeve 28 and is rubbed by the bristles 33, so that the dust on the detection electrode 27 of the four-electrode probe 24 can be cleaned in real time, preventing the accumulation of dust from changing the conductivity of the detection electrode 27, thereby making the resistance detection of the electrode plate more accurate.

[0034] Furthermore, a support plate 17 is provided on the top of the servo stage 2 13, and a placement opening 18 is provided on the top outer wall of the support plate 17. Both the electrode body 11 and the electrode body 2 12 are adapted to the placement opening 18. When the electrode body 11 or the electrode body 2 12 is being tested, the electrode body 11 or the electrode body 2 12 is placed inside the placement opening 18, so that the two thickness detection probes 15 are located at the top and bottom of the electrode respectively.

[0035] A fully automated electrode plate detection method includes the following steps: Feeding steps: Place both electrode body 11 and electrode body 2 12 on servo table 10. Use robot arm 3 8 to grab electrode body 2 12. When one electrode body 2 12 is grabbed, servo table 10 rises to the height of one electrode body 2 12. After all electrode bodies 2 12 are grabbed, servo table 10 descends and moves electrode body 11 to the bottom of robot arm 3 8. Dust removal steps: The robotic arm 38 places the gripped electrode body 2 12 or electrode body 1 11 inside the dust removal mechanism 3 for dust removal. After the electrode body 2 12 or electrode body 1 11 is dusted, the robotic arm 27 places the electrode body 2 12 or electrode body 1 11 inside the placement port 18. Thickness detection steps: The servo stage 13 drives the motion frame 14 to move horizontally and vertically, so that the thickness detection probe 15 detects the thickness of the electrode body 12. The thickness detection probe 15 transmits the detected thickness data to the control box 9, and the control box 9 determines whether the thickness is qualified. Resistance step: After the thickness is measured, the electric telescopic rod 23 drives the four-electrode probe 24 to measure the resistance of the electrode body 2 12 or the electrode body 1 11. The four-electrode probe 24 transmits the measured resistance data to the control box 9, and the control box 9 determines whether the resistance is qualified. Material feeding steps: After the resistance test is completed, the qualified products in the electrode body 12 or electrode body 11 are placed on the bearing mechanism 21 by the robot arm 16. When the robot arm 16 picks up the unqualified products, the control box 9 controls the servo stage 3 19 to work, so that the servo stage 3 19 moves the bearing mechanism 20 to the bottom of the robot arm 16, so that the robot arm 16 places the unqualified products on the bearing mechanism 20. Then, the servo stage 3 19 drives the bearing mechanism 20 to reset, and the labeling device 22 prints the label of the unqualified products and affixes the label to the upper surface of the unqualified products.

[0036] In another embodiment of the present invention, in the thickness detection step, the control box 9 calculates the difference between the received thickness data and the previously detected thickness data to obtain a thickness compensation parameter; in the resistance step, the control box 9 calculates the stroke amount according to the compensation parameter and controls the electric telescopic rod 23 to move. The displacement sensor 25 measures the stroke amount of the electric telescopic rod 23 and transmits the measured data to the control box 9. When the stroke amount measured by the displacement sensor 25 matches the calculated stroke amount, the control box 9 controls the electric telescopic rod 23 to stop working. At this time, the four-electrode probe 24 transmits the detected resistance data to the control box 9. By calculating the difference between plates of different thicknesses as a compensation parameter, the resistance detection component 16 can automatically adjust according to the compensation parameter when performing resistance detection on plates of different thicknesses, thereby ensuring the accuracy of the resistance detection parameters.

[0037] In another embodiment of the present invention, during the resistance step, the pressure sensor 40 detects the pressure between the connecting block 39 and the moving frame and transmits the detected pressure data to the control box 9. When the control box 9 determines that the pressure value is greater than a predetermined value, the control box 9 controls the electric telescopic rod 23 to stop working. At this time, the four-electrode probe 24 transmits the detected resistance data to the control box 9. At the same time, the pressure sensor 40 monitors the force during resistance detection, so that when the pressure reaches the predetermined value, the electric telescopic rod 23 is controlled to stop, preventing the phenomenon of impacting the electrode plate when the compensation coefficient is calculated incorrectly, thereby ensuring that the four-electrode probe 24 will not be damaged due to excessive force.

[0038] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
