After the film tearing mechanism 25 tears the film, the adhesive tape is positioned on the convex portion 2620, then the first electric sliding table 260 moves the adhesive tape jig plate 262 thereon to a position under the film pushing jig 285, then the second linear stepping motor 281 drives the film pushing jig 285 to descend, so that the lug 2852 is inserted into the groove 2853, and when the lug 2852 is positioned in the groove 2953, the adhesive tape adhesive surface is not in contact with the film pushing jig 285, so as to prevent the adhesive tape from adhering to the film pushing jig 285; then the first electric sliding table 260 moves the rubber strip jig plate 262 to one direction, so that the lug 2852 is extruded with the side wall of the convex part 2620, and if the rubber strip protruding out of the side wall of the convex part 2620 exists, the rubber strip is pushed to be aligned with the side wall of the convex part 2620; after that, the second electric sliding table 260 moves the adhesive tape fixture plate 262 in the opposite direction, so that the protruding piece 2852 is pressed against the side wall of the other side of the protrusion 2620, and similarly, the adhesive tape protruding out of the side wall of the protrusion 2620 can be aligned with the side wall of the protrusion 2620. During compression, the spring 287 acts as a buffer and return to prevent damage to the protrusions 2620 and tabs 2852. The strip shown in FIG. 20 is the first strip 11 with the right side protruding from the right side wall of the protrusion 2620. only movement of the tab 2852 to the left will align the first strip 11 with the right side wall of the protrusion 2620. It will be appreciated that the vacuum generator for generating the negative pressure to the suction holes 263 does not need to be operated during the alignment so that the adhesive tape can smoothly move on the protrusions 2620, and the vacuum generator continues to operate after the alignment is completed. The tab 2852 may be coated with a release coating, such as a teflon coating, to prevent the adhesive strip from adhering to the tab 2852.
The step of aligning the glue strips on the second transplanting module 27 is substantially the same as that of the first transplanting module 26, except that the second cylinder 274 on the second transplanting module 27 needs to be extended first to make the height of the glue strip fixture plate 262 thereon sufficient, and then the glue strip shaping mechanism 28 can align the glue strips.
As shown in fig. 21, the steel sheet transplanting manipulator 20 is used for sucking the steel sheet 10 at the steel sheet feeding mechanism 6 and attaching the adhesive tape, and includes: a second multi-axis robot 200 fixed on the bedplate 2a, a connecting bracket 201 connected with the tail end of the second multi-axis robot 200, and two groups of sucker assemblies 202 connected with the connecting bracket 201.

Because the steel sheet transplanting manipulator 20 is provided with the two groups of suction head assemblies 202, two steel sheets 10 can be adsorbed, when one of the steel sheets 10 is driven to move downwards to attach the adhesive tape, the third cylinder 2020 of the other suction head assembly 202 retracts, so that the height of the steel sheet 10 on the suction head assembly is higher, and the adhesive tape is prevented from being accidentally taken away when the suction head assembly touches the adhesive tape. That is, the two steel sheets 10 are aligned and attached one by one, which can greatly improve the accuracy of the attachment.
In order to move the steel sheet with the adhesive tape adhered to the previous adhering station to the next adhering station, a steel sheet transplanting mechanism 29 is further arranged between every two adjacent adhering stations, and after the adhesive tape is adhered to the steel sheet 10, the second multi-axis robot 200 places the steel sheet 10 on the steel sheet transplanting mechanism 29 and moves the steel sheet transplanting mechanism 29 to the next work station.
