The connection frame 283 includes a middle plate 2830 located inside the second frame body 280 and support plates 2831 located on both sides of the middle plate 2830. The support plates 2831 are connected with the nuts 282 on the second linear stepping motor 281, so that the connection frame 283 can be Moving up and down. Of course, a guide device such as a sliding rail can be provided between the connecting frame 283 and the second frame body 280 so that the connecting frame 283 can move up and down accurately. The rubber strip shaping mechanism 28 further includes a third sliding rail 284 disposed at the bottom of the middle plate 2830 and a film pushing jig 285 connected below the third sliding rail 284 .

The corresponding mounting holes 2851 are provided with springs 287 in the mounting holes 2851 .

A plurality of protruding tabs 2852 are disposed on the lower surface of the film pushing fixture 285 , and the protruding tabs 2852 correspond to the grooves 2853 between the protruding portions 2620 . The film pushing jig 285 is used to accurately move the rubber strip to the convex portion 2620, so as to prevent the occurrence of defects such as skew of the rubber strip. After the film tearing mechanism 25 tears off the film, the adhesive strip is located on the convex portion 2620, and then the first electric sliding table 260 moves the adhesive strip jig plate 262 on it to just below the film pushing jig 285, and then the second linear step The motor 281 drives the film pushing jig 285 to descend, so that the protruding piece 2852 is inserted into the groove 2853. When the convex piece 2852 is located in the groove 2953, the adhesive surface of the adhesive tape does not contact the film pushing jig 285 to prevent the adhesive tape from sticking. Attached to the film pusher jig 285; then the first electric slide 260 moves the rubber strip jig plate 262 in one direction, so that the protruding piece 2852 is pressed against the side wall of the protruding portion 2620. The rubber strip will be pushed to align with the side wall of the convex part 2620 ; after that, the second electric slide 260 moves the rubber strip fixture plate 262 in the opposite direction, so that the convex piece 2852 is pressed against the side wall of the other side of the convex part 2620 Similarly, the rubber strip protruding from the side wall of the convex portion 2620 can be aligned with the side wall of the convex portion 2620 . During the extrusion process, the spring 287 can play a role of buffering and restoring, preventing the protrusion 2620 and the protrusion 2852 from being crushed. The rubber strip shown in FIG. 20 is the first rubber strip 11 , the right side of which protrudes from the right side wall of the convex portion 2620 , and the first rubber strip 11 and the convex portion 2620 only need to be moved to the left by moving the convex piece 2852 to the left. The right side wall is aligned. It can be understood that, during the alignment process, the vacuum generator for generating negative pressure in the suction holes 263 does not need to work, so that the rubber strip can move smoothly on the convex portion 2620, and after the alignment is completed, the vacuum generator continues to work. Tabs 2852 may be coated with a release coating, such as a Teflon coating, to prevent adhesive strips from sticking to tabs 2852.

The step of aligning the rubber strips on the second transplanting module 27 is basically the same as that of the first transplanting module 26, the difference is that the second air cylinder 274 on the second transplanting module 27 needs to be extended first to make it The height of the glue strip jig plate 262 is sufficient, and then the glue strip shaping mechanism 28 can align the glue strips.

For the head 2022, similarly, the first steel sheet suction head 2022 sucks the steel sheet 10 through negative pressure. The third air cylinder 2020 can drive the first steel sheet suction head 2022 to extend or retract. When the two third air cylinders 2020 are in different states, the first steel sheet suction heads 2022 on the two groups of suction head assemblies 202 can be displaced in height and low .

As shown in FIG. 23 , the steel sheet photographing assembly 21 includes a first column 210 and a second column 211 arranged at intervals, and a second CCD camera 212 and a second light source 213 are arranged on the first column 210 and the second column 211. The second light source 213 is located below the second CCD camera 212, and both the second CCD camera 212 and the second light source 213 are disposed downward.

The steel sheet photographing component 21 is used to judge whether the position of the steel sheet 10 is appropriate. As shown in FIG. 23 , during operation, firstly, the first transplanting module 26 or the second transplanting module 27 moves the adhesive strip jig plate 262 carrying the adhesive strip to just below the steel sheet photographing assembly 21 , and then the steel sheet The transplanting manipulator 20 moves the sucked steel sheet 10 between the glue strip jig plate 262 and the second CCD camera 212 . At this time, the two ends of the glue strip and the steel sheet 10 are located within the shooting range of the two second CCD cameras 212 , the control system can control the second multi-axis robot 200 to adjust the position of the steel sheet 10 relative to the glue strip according to the shooting results. After adjusting to the appropriate position, the second multi-axis robot 200 moves the steel sheet 10 to vertically descend until it squeezes the glue below. Since the adhesive side of the adhesive strip is facing upward, the adhesive strip will be attached to the steel sheet 10, and then the adhesive strip jig plate 262 stops generating negative pressure, and the second multi-axis robot 200 can remove the steel sheet 10 together with the adhesive strips are removed together.

Since the steel sheet transplanting manipulator 20 is provided with two sets of suction head assemblies 202, two steel sheets 10 can be adsorbed. When driving one of the steel sheets 10 downward to attach the adhesive strip, the third air cylinder of the other suction head assembly 202 The 2020 retracts so that the height of the steel sheet 10 on it is higher, preventing the adhesive strip from being accidentally taken away by touching it. That is to say, the two steel sheets 10 are aligned and attached one by one, which can greatly improve the attachment accuracy.

In order to move the steel sheet with the glue strip attached at the previous attachment station to the next attachment station, a steel sheet transplanting mechanism 29 is also arranged between the two adjacent attachment stations, and the glue strip is attached to the steel sheet 10.
