One side surface of the five-in-one material belt a5 faces upwards (namely an upper side surface) and the other side surface faces downwards (namely a lower side surface) in the belt conveying process. The dispensing assembly 50 is used for dispensing to the upper side surface of the five-in-one tape a5. The attaching unit 60 is used for simultaneously sucking the M GDL sheets a41 on the first conveying unit 20, and attaching to the upper side surface of the five-in-one material belt a5.

The second transfer mechanism 75 may be a vacuum chuck robot, the detection and transfer mechanism 76 may be a vacuum chuck robot, and the dispensing and transfer mechanism 78 may be a vacuum chuck robot. Since the upper side surface of each GDL sheet a41 on the dispensing mechanism 73 is only partially dispensed, the second transfer mechanism 75, the detection and conveyance mechanism 76, and the dispensing and conveyance mechanism 78 adsorb portions of the upper side surface of the GDL sheet a41 where no dispensing is performed in order to avoid damage to the dispensing area.

Referring to fig. 4, in the embodiment, the dispensing mechanism 73 includes a carrying portion 731 and a dispensing portion 732, where the carrying portion 731 includes a transferring base 7310 and M second deviation correcting platforms 7311 disposed on the transferring base 7310. Each second deviation rectifying platform 7311 is used for carrying a GDL sheet a41, and can be controlled to adjust the position relative to the transfer base 7310, that is, each second deviation rectifying platform 7311 can independently drive the respective GDL sheet a41 to rectify the deviation, so as to ensure that the dispensing accuracy of the dispensing portion 732 on dispensing the respective GDL sheet a41 meets the process requirement.

Further, the dispensing mechanism 73 further includes a second visual positioning mechanism 733 communicatively coupled to each of the second deviation correcting platforms 7311. The second visual positioning mechanism 733 is used to detect the position of the GDL sheet a41 on each second deviation correcting platform 7311. Each second deviation rectifying platform 7311 is used for adjusting the position according to the detection result of the second visual positioning mechanism 733, so as to ensure that the dispensing accuracy of the dispensing portion 732 on each GDL sheet a41 meets the process requirements. Alternatively, the second visual positioning mechanism 733 may employ a CCD (charge coupled device ) camera.

In one embodiment, the second visual positioning mechanism 733 detects the positions of two corners of the GDL sheet a41 on each second deviation correcting platform 7311, which are diagonally opposite, to determine the position of the GDL sheet a 41. Specifically, in the embodiment shown in fig. 5, m=4, the second visual positioning mechanism 733 includes 5 CCD cameras, the first CCD camera detects the position of the upper left corner of the 1 st GDL piece a41, the second CCD camera detects the position of the lower right corner of the 1 st GDL piece a41 and the upper right corner of the 2 nd GDL piece a41, the third CCD camera detects the position of the lower left corner of the 2 nd GDL piece a41 and the upper left corner of the 3 rd GDL piece a41, the fourth CCD camera detects the position of the lower right corner of the 3 rd GDL piece a41 and the position of the upper right corner of the 4 th GDL piece a41, and the fifth CCD camera detects the position of the lower left corner of the 4 th GDL piece a 41. Of course, the second visual positioning mechanism 733 may employ other position detection methods as long as the position of each GDL sheet a41 can be detected, and is not limited thereto.

With continued reference to fig. 1 and 2, the dispensing mechanism 73 further includes a third visual positioning mechanism 791 communicatively coupled to the laminating mechanism 79. The third visual positioning mechanism 791 is configured to detect the positions of the M GDL sheets a41 on the attaching mechanism 79, and the attaching mechanism 79 can perform position adjustment (i.e., deviation correction) on the M GDL sheets a41 on the second visual positioning mechanism 733 according to the detection result, so as to ensure that the M GDL sheets a41 on the attaching mechanism 79 can be accurately attached to the lower side surface of the five-in-one material tape a 5.
