Referring to fig. 1, a membrane electrode test apparatus 10 according to an embodiment of the present invention includes a testing device 100 and a loading/unloading device 200.

The detection device 100 has a visual detection station and at least two air tightness detection stations, and specifically, as shown in fig. 1, each detection device 100 in this embodiment has three air tightness detection stations and one visual detection station. Wherein, the visual detection station is provided with a visual detection mechanism 110, and each air tightness detection station is provided with an air tightness detection mechanism 120. The visual inspection mechanism 110 can perform visual inspection on the membrane electrode located at the visual inspection station to determine whether the membrane electrode has surface defects, poor alignment, and other problems. The air tightness detection mechanism 120 can perform air tightness detection on the membrane electrode entering the corresponding air tightness detection station to determine whether the membrane electrode has poor air tightness.

Further, the detection apparatus 100 further includes a transfer mechanism 130, and the transfer mechanism 130 can drive the membrane electrode to be detected to be transferred between the visual detection station and any air tightness detection station. Specifically, after the membrane electrode on any air tightness detection station is qualified, the membrane electrode can be transferred to the visual detection station by the transfer mechanism 130 for visual detection. After the visual inspection is finished, the transfer mechanism 130 moves the membrane electrode back to the original air tightness inspection station.

The loading and unloading device 200 can transfer the membrane electrode to be detected of the loading station 101 to the material taking position, and transfer the membrane electrode which is detected to the good product station 102 or the waste material station 103 from the material taking position. Moreover, the transfer mechanism 130 can also transfer the membrane electrode to be detected located at the material taking position to any air tightness detection station, and transfer the membrane electrode subjected to detection from any air tightness detection station to the material taking position. The material taking position is located between the detection device 100 and the loading and unloading device 200, and can play a transition role.

When the membrane electrode is detected, the loading and unloading device 200 can firstly transfer the membrane electrode to be detected to a material taking position from the loading station 101; then, the transferring mechanism 130 transfers the membrane electrode to be tested to any idle air tightness detection station from the material taking position to perform air tightness detection; if the air tightness is detected to be unqualified, the transferring mechanism 130 directly transfers the membrane electrode to a material taking position, and the loading and unloading device 200 sorts the membrane electrode from the material taking position to the waste material station 103; if the air tightness detection is qualified, the transferring mechanism 130 transfers the membrane electrode to a visual detection station to continue the visual detection; if the visual detection is qualified, the membrane electrode is good, the transfer mechanism 130 transfers the membrane electrode to the original air tightness detection station, then transfers the membrane electrode to the material taking position from the air tightness detection station, and sorts the membrane electrode to the good product station 102 from the material taking position by the loading and unloading device 200; if the membrane electrode is not qualified in the visual detection, the loading and unloading device 200 sorts the membrane electrode to the waste material station 103 from the material taking position.

When the membrane electrode detection device 10 is actually operated, the air tightness detection mechanisms 120 on at least two air tightness detection stations can simultaneously perform air tightness detection. Because the time required by the air tightness detection is long, in the time period of the air tightness detection of one air tightness detection station, the transfer mechanism 130 can transfer the membrane electrode for completing the air tightness detection of other air tightness detection stations to the visual detection station or the material taking position, and the feeding and discharging device 200 can also perform feeding and discharging aiming at the material taking position, so that the detection beat is obviously improved.

Referring to fig. 2, in the present embodiment, the transferring mechanism 130 includes a transferring rail 131, a first suction pad gripper 132 and a second suction pad gripper 133. The first sucker gripper 132 and the second sucker gripper 133 can respectively slide along the transfer rail 131, the first sucker gripper 132 can suck the membrane electrode and drive the membrane electrode to transfer between the visual detection station and any air tightness detection station, and the second sucker gripper 133 can suck the membrane electrode and drive the membrane electrode to transfer between the material taking position and any air tightness detection station.

The transfer rail 131 generally extends along a straight line, in the left-right direction as shown in fig. 2. The first and second suction gripper 132 and 133 can move along the transfer rail 131 independently without interfering with each other. The first and second suction gripper 132 and 133 may be driven by a driving chain, respectively, to move along the transfer rail 131. When the first suction cup gripper 132 transfers the membrane electrode which completes the air tightness detection to the visual detection station or moves the membrane electrode which completes the visual detection back to the air tightness detection station, the second suction cup gripper 133 can simultaneously transfer the membrane electrode which completes the detection of other air tightness detection stations to the material taking position to realize blanking, and can also transfer the membrane electrode to be detected at the material taking position to other idle air tightness detection stations to realize loading. Therefore, the feeding and discharging operation of the membrane electrode and the circulation of the membrane electrode among all stations can be simultaneously carried out, so that the detection beat can be further improved.

Further, in this embodiment, the visual inspection station and the at least two air-tightness inspection stations are arranged along the extending direction of the transfer rail 131, and the visual inspection station is located on one side of the at least two air-tightness inspection stations away from the loading and unloading device 200. So set up, can avoid effectively taking place alternately between the route of going up unloading operation and the route of membrane electrode stream to reduce mutual interference as far as possible.

The three air tightness detection stations from left to right shown in fig. 1 are sequentially marked as No. 1, no. 2 and No. 3 air tightness detection stations, and the actual working process of the membrane electrode detection device 10 is approximately as follows:

when the No. 1 air tightness detection station detects, the second sucker claw 133 returns to the material taking position to grab the second membrane electrode and place the second membrane electrode on the No. 2 air tightness detection station, and then returns to the material taking position again to grab the third membrane electrode and place the third membrane electrode on the No. 3 air tightness detection station; after the membrane electrode of the air tightness detection station No. 1 is detected, unqualified membrane electrodes are directly returned to the material taking position by the second sucker gripper 133 and then sorted to the waste material station 103 by the loading and unloading device 200, and the membrane electrodes qualified in air tightness detection are transferred to the visual detection station by the first sucker gripper 132 for visual detection; after the visual inspection is finished, the first suction cup gripper 132 grips the membrane electrode and puts the membrane electrode back to the No. 1 air tightness detection station, and then the membrane electrode is sent back to the material taking position by the second suction cup gripper 133 and sorted by the loading and unloading device 200. While the second chuck gripper 133 acts, the first chuck gripper 132 can grip the membrane electrode whose airtightness detection station No. 2 has been completed, and transfer the membrane electrode to the visual detection station for visual detection. Then, while the second sucker claw 133 conveys the first membrane electrode to the material taking position, the second sucker claw 133 can grab the fourth membrane electrode from the material taking position and place the fourth membrane electrode on the vacated No. 1 air tightness detection station for air tightness detection, the first sucker claw 132 conveys the second membrane electrode back to the No. 2 air tightness detection station, and the second sucker claw 133 conveys the second membrane electrode back to the material taking position for sorting; then, the second sucker claw 133 grabs the fifth membrane electrode and places the fifth membrane electrode on the vacated No. 2 air tightness detection station; the third membrane electrode completes detection in the same way and is sent back to the material taking position for sorting, and the detection can be continuously carried out on a plurality of membrane electrodes after sequential circulation.

Therefore, the loading and unloading device 200 is matched with the transfer mechanism 130, so that the membrane electrode can be automatically loaded and unloaded and circulated. Moreover, the loading and unloading device 200 and the transfer mechanism 130 can cooperate with each other to realize the loading and unloading of the membrane electrode. The loading and unloading device 200 does not need to directly place the membrane electrode to be detected at the air tightness detection station, and the transferring mechanism 130 does not need to sort the membrane electrode after detection, so that the strokes of the two can be reduced. Therefore, the detection efficiency of the membrane electrode detection device 10 can be significantly improved.

Referring to fig. 1 again, in the present embodiment, at least two detection devices 100 are provided, and each detection device 100 is correspondingly provided with one material taking position, the loading and unloading device 200 can sequentially transfer the membrane electrodes to be detected of the loading station 101 to each material taking position, and sequentially transfer the membrane electrodes that have been detected from each material taking position to the good product station 102 or the waste material station 103.

The time required for completing the detection of one membrane electrode is generally far longer than the time required for transferring one membrane electrode to be detected to the material taking position and sorting one membrane electrode completing the detection to the good product station 102 or the waste material station 103 by the loading and unloading device 200. Therefore, the arrangement of at least two detection devices 100 can enable the beats of the loading and unloading device 200 and the detection devices 100 to be more matched, so that the pause time of the loading and unloading device 200 is reduced as much as possible, and the detection efficiency is further improved.

In addition, the membrane electrode detection device 10 further includes a large plate 300 for supporting, and the detection apparatus 100 and the loading and unloading apparatus 200 are mounted on the large plate 300. Moreover, the loading station 101, the good product station 102 and the waste station 103 are all arranged on the large plate 300.

Specifically, in this embodiment, the membrane electrode detection apparatus 10 further includes a material frame 400 disposed in the feeding station 101, the good product station 102, and the waste material station 103.

Each membrane electrode test device 10 is generally provided with a plurality of material frames 400. The membrane electrode to be tested can be placed in the material frame 400 first, and the material frame 400 fully loaded with the membrane electrode to be tested is manually placed in the feeding station. When the membrane electrode to be tested in one material frame 400 is taken out, a new material frame 400 fully loaded can be quickly replaced. The good product stations 102 and the waste stations 103 can be pre-placed with empty material frames 400, and the membrane electrodes sorted to the good product stations 102 and the waste stations 103 by the loading and unloading device 200 can be respectively placed on the corresponding material frames 400 for collection. When one of the frames 400 is filled with the membrane electrode whose detection is completed, a new empty frame 400 can be quickly replaced. The material frame 400 can adopt a cartridge clip type material loading and unloading mode, so that the membrane electrodes are positioned on the same horizontal plane when being loaded and unloaded, and the membrane electrodes are convenient to grab and place.

Further, referring to fig. 7, in the present embodiment, the material frame 400 includes a bottom plate 410 and a plurality of positioning guide pillars 420 mounted on the surface of the bottom plate 410, the plurality of positioning guide pillars 420 surround an accommodating space capable of limiting the membrane electrode, and the positions of the plurality of positioning guide pillars 420 are adjustable to adjust the size of the accommodating space. Therefore, the material frame 400 can be adapted to membrane electrodes of different models by adjusting the position of the positioning guide pillar 420, so that the application range of the membrane electrode detection device 10 is expanded.

Referring to fig. 3, in the present embodiment, the loading and unloading apparatus 200 includes a sorting mechanism 210 and a transition mechanism 220, the transition mechanism 220 includes a carrier 221, the carrier 221 is used for carrying a membrane electrode and can move between a material taking position and a material receiving position, the sorting mechanism 210 can transfer the membrane electrode to be tested in the material loading station 101 to the carrier 221 in the material receiving position, and can transfer the membrane electrode to be tested from the carrier 221 in the material receiving position to the non-good product station 102 or the waste material station 103.

The material taking position and the material receiving position are arranged at intervals, and the material receiving position is located on one side, close to the material loading station 101, of the material taking position. Specifically, the receiving position is located on the right side of the material taking position as shown in fig. 1. The sorting mechanism 210 may be composed of a three-axis servo and a suction cup claw, and the material loading station 101, the good product station 102, and the waste material station 103 are butted with the transition mechanism 220 in a three-axis moving manner. Because the material receiving position is closer to the material loading station 101 than the material taking position, the sorting mechanism 210 does not need to extend to the material taking position during the material loading and unloading operation, the stroke can be reduced, and the detection efficiency of the membrane electrode detection device 10 can be further improved.

In addition, the transition mechanism 220 further includes a transition rail 222, and the stage 221 is slidably mounted on the transition rail 222. Transition track 222 connects and gets material position and connect the material position, and microscope carrier 221 slides along transition track 222 and can realize switching between getting the material position and receiving the material position, and transition track 222 can promote the stability of microscope carrier 221 in the position switching process.

In the case where a plurality of detection apparatuses 100 are provided, a plurality of transition mechanisms 220 are provided correspondingly. The sorting mechanism 210 can transfer the membrane electrode to be detected of the feeding station 101 to the carrier 221 located at any material receiving position, and can transfer the detected membrane electrode from the carrier 221 located at any material receiving position to the good product station 102 or the waste material station 103.

Further, in the present embodiment, the stage 221 can accommodate at least two membrane electrodes at the same time. Specifically, the width of the stage 221 may be set to be greater than the sum of the widths of the two membrane electrodes. In the operation process, a membrane electrode to be detected is placed on the right half part (the side close to the loading station 101) of the carrier 221, and a membrane electrode which is detected is placed on the left half part (the side close to the detection device 100). In this way, before sorting the membrane electrodes that have been detected on the stage 221, the sorting mechanism 210 may first place the membrane electrodes to be detected, which are captured by the feeding station 101, on the stage 221. That is to say, the sorting mechanism 210 does not need to sort the membrane electrodes that have been detected on the carrier 221 first to vacate the carrier 221, so as to save the flow of mechanical actions and further improve the detection efficiency.

Referring to fig. 4 and 5, in this embodiment, the vision inspection mechanism 110 includes a moving plate 111, a first vision camera 112 and a second vision camera 113, the moving plate 111 can be switched between a first inspection position and a second inspection position, the first vision camera 112 is disposed below the first inspection position, the second vision camera 113 is disposed above the second inspection position, the transfer mechanism 130 can transfer the membrane electrode of any air tightness inspection station to the first inspection position, and the membrane electrode can be transferred between the transfer mechanism 130 and the moving plate 111 located at the first position.

Specifically, the visual inspection mechanism 110 further includes a support frame 114, and the moving plate 111 is mounted on the support frame 114 through a guide rail and can be driven by a driving element such as an air cylinder or a motor to switch between the first inspection position and the second inspection position.

When the transferring mechanism 130 transfers the membrane electrode from the air tightness detection station to the visual detection station, the membrane electrode is at the first detection position. The transfer mechanism 130 is attached to the upper surface of the membrane electrode, and does not shield the lower surface. At this time, the moving plate 111 is at the second detection position, and the first vision camera 112 below the first detection position can photograph the lower surface of the membrane electrode for detection (see fig. 5); subsequently, the moving plate 111 is moved to the first detection position, and the transfer mechanism 130 places the membrane electrode on the moving plate 111; the moving plate 111 is returned to the second inspection position, so that the second vision camera 113 above the second inspection position performs a photographing inspection of the upper surface of the membrane electrode (see fig. 4). Thus, visual inspection of both surfaces of the membrane electrode can be accomplished. After the visual detection is completed, the moving plate 111 is moved to the first detection position again, and the transferring mechanism 130 grabs the membrane electrode on the moving plate 111 and moves the membrane electrode back to the air tightness detection station.

Referring to fig. 6, in the present embodiment, the air-tightness detecting mechanism 120 includes a tooling plate 121 and a pressing assembly 122, the tooling plate 121 can be switched between an exchange position and a pressing position, the membrane electrode can be transferred between the transferring mechanism 130 and the tooling plate 121 located at the exchange position, and the tooling plate 121 located at the pressing position can cooperate with the pressing assembly 122 to clamp the membrane electrode.

The hermeticity detecting mechanism 120 further includes a bottom support structure 123, and the tooling plate 121 may be mounted to the bottom support structure 123 through a guide rail. The hold-down assembly 122 generally includes a hold-down cylinder, guide rods, and a platen, the hold-down cylinder being capable of driving the platen down along the guide rods. The membrane electrode transferred to the air tightness detection station by the transfer mechanism 130 is located at the exchange position, and after the membrane electrode to be detected is placed on the tooling plate 121 located at the exchange position by the transfer mechanism 130, the tooling plate 121 drives the membrane electrode to be detected to move to the compression position. Then, the pressing component 122 presses down to clamp the membrane electrode to be tested, so as to perform air tightness test on the membrane electrode.

After the air tightness detection is completed, the tooling plate 121 drives the membrane electrode to return to the exchange position, and the transfer mechanism 130 can grasp the membrane electrode on the tooling plate 121. It can be seen that the hold-down assembly 122 and the mechanism for detecting the air tightness of the membrane electrode can be disposed away from the operation route of the transfer mechanism 130. Thus, the airtightness detection mechanism 120 will not interfere with the operation of the transfer mechanism 130.

The membrane electrode detection equipment 100 can realize the automatic feeding and circulation of the membrane electrode by matching the feeding and discharging device 200 with the transfer mechanism 130. The air tightness detection mechanisms 120 on at least two air tightness detection stations can simultaneously perform air tightness detection, the transfer mechanism 130 can perform membrane electrode exchange between other air tightness detection stations and a visual detection station in the time period when one air tightness detection station performs air tightness detection, and the loading and unloading device 200 can also perform loading and unloading on the material taking position, so that the detection rhythm is obviously improved. Moreover, the loading and unloading device 200 and the transfer mechanism 130 can exchange the membrane electrode at the material taking position, so that the loading and unloading of the membrane electrode are realized cooperatively, and the strokes of the two devices can be reduced. Therefore, the membrane electrode detection device 10 can effectively improve the detection efficiency.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
