In the above embodiment, only the structure of the placement seat 01 cooperating with the limiting surface 02, the fixing device 03, the adhering device 04, the laser sensor 05 and the fastening mechanism 06 is described, which form a processing station. In a more preferred embodiment, in order to improve the assembly efficiency, as shown in fig. 7, the processing stations are preferably multiple (in one group), that is, the placing seats 01 are multiple and arranged side by side, and each placing seat 01 cooperates with one of the limiting surfaces 02, the fixing device 03, the adhering device 04, the laser sensor 05 and the fastening mechanism 06. In the multi-station structure, parts of the plurality of sticking devices 04 can share the same sticking moving device for driving the grabbing jaw 040 to move, for example, when the number of the processing stations is six, the sticking devices 04 at the two middle stations can share one set of servo linear module, and the two stations at the two sides use one servo linear module respectively.

In the configuration of the plurality of processing stations, as shown in fig. 7, the laser sensors 05 of the plurality of processing stations may be disposed on the same T-shaped frame 08 at the same height, the laminated plates of the plurality of fastening mechanisms 06 may be disposed on one cross bar 065 in common, and both ends of the cross bar 065 may be connected to large air cylinders, respectively.

Furthermore, the blanking is needed after the attachment is finished, and if only one group of a plurality of processing stations are arranged, the assembly cannot be continuously carried out during the blanking, so that the waste of time is caused. Therefore, as shown in fig. 1 and 7, the stage 00 is disposed on a turntable 07 that drives the stage to rotate, and the specific structure of the turntable 07 is a known technology and is not an innovation point of the present invention, and is not described here again.

When the cylinder shaft of the cylinder retracts, the paper removing clamping jaw moves the head of the protective paper clamped by the paper removing clamping jaw towards the direction far away from the end face of the battery cell module, so that the head of the protective paper is separated from the colloid. Then, the driving device 3400 drives the paper removing gripper 3100 to move linearly toward the other end of the protective paper, so that the protective paper can be peeled off from the adhesive layer.
