Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5The utility model provides an embodiment: a multi-camera strip cutting machine based on visual guidance, comprising a frame 1 and a feeder rack 2 fixed at the top of the frame 1, and a support plate 6 is installed on the top slope wall of the feeder rack 2, two symmetrical support arms 3 are installed on the outer wall of the side of the feeder rack 2 away from the frame 1, and a strip feeding and traction structure 4 for conveying film strips is arranged between the two support arms 3, a steel roller 8 is rotatably installed inside the feeder rack 2 above the support arms 3, a cylinder 7 is installed on the back of the support plate 6, the top of the piston rod of the cylinder 7 penetrates the outside of the support plate 6 and is installed with a cross plate 5, the bottom edge of the cross plate 5 is integrally formed with a right-angle support edge 501, and a plurality of threaded limiting cutting strip structures 10 for dividing the film strips are installed on the outer wall of the right-angle support edge 501, and a PLC control panel 9 is installed on the outer wall of one side of the feeder rack 2, and the output end of the PLC control panel 9 is electrically connected to the input end of the cylinder 7 and the strip feeding and traction structure 4;

[0020] The cylinder 7 pulls the cross plate 5, the threaded limiting cutting strip structure 10 and other components to move toward the support plate 6 until the blade of the threaded limiting cutting strip structure 10 is pressed against the steel roller 8. At this time, the film strip is located between the steel roller 8 and the threaded limiting cutting strip structure 10.

[0021] The staff can install a CCD industrial camera on the support plate 6 opposite to the threaded limiting cutting strip structure 10, and use the CCD industrial camera to shoot the cutting condition of the film strip by the threaded limiting cutting strip structure 10, so as to observe whether the film strip is cut by the threaded limiting cutting strip structure 10;

[0022] Two symmetrical feed rollers 201 are rotatably installed inside the feed frame 2 on one side of the support plate 6. The height of the feed rollers 201 is higher than the top edge height of the support plate 6. When the film strip is laid flat on the support plate 6, the two feed rollers 201 assist the film strip to be pulled and moved;

[0023] The strip feeding and traction structure 4 includes two sponge rollers 402 rotatably mounted between the two supporting arms 3, one end of the two sponge rollers 402 both penetrates the outside of the supporting arms 3 and is installed with a gear transmission structure 403 for maintaining power connection, a stepper motor 401 for driving one of the gear transmission structures 403 to rotate is installed on the inner wall of one side of the feeding rack 2, a belt transmission structure is installed at the output end of the stepper motor 401, and the output end of the stepper motor 401 is connected to one end of one of the sponge rollers 402 through the belt transmission structure. When the film strip is being pulled, the film strip passes between the two sponge rollers 402, and the sponge rollers 402 exert a certain squeezing force on the film strip, and the rotary power of the stepper motor 401 is transmitted to one of the sponge rollers 402 through the belt transmission structure, while the other sponge roller 402 rotates synchronously in the opposite direction driven by the gear transmission structure 403, thereby realizing the traction and conveying function of the film strip;

[0024] The threaded limited cutting strip structure 10 comprises a C-shaped sleeve 1001 slidably mounted on the surface of the right-angle support edge 501, and a threaded column 1002 threadedly mounted at the bottom end of the C-shaped sleeve 1001, the top end of the threaded column 1002 extends to the inside of the C-shaped sleeve 1001 and is installed with a silicone plate 1003, and a cutter 1004 is fixed on the outer wall of the C-shaped sleeve 1001 away from the right-angle support edge 501. When the cylinder 7 pulls the cross plate 5 and the threaded limited cutting strip structure 10 moves, the cutter 1004 presses on the steel roller 8, thereby producing a cutting effect on the film passing through the surface of the steel roller 8;

[0025] The top wall of the C-shaped sleeve 1001 is provided with a rectangular protrusion, and the bottom of the right-angled support edge 501 is provided with a rectangular groove. The C-shaped sleeve 1001 and the right-angled support edge 501 are slidably connected through the rectangular protrusion and the rectangular groove. The staff slides the C-shaped sleeve 1001 onto the right-angled support edge 501, and the protrusion on the top wall of the C-shaped sleeve 1001 and the groove on the bottom wall of the right-angled support edge 501 match each other, so as to ensure that the threaded limited cutting strip structure 10 is stably installed on the right-angled support edge 501;

[0026] After the C-shaped sleeve 1001 moves to the appropriate position, the staff continues to rotate the threaded column 1002, and the threaded column 1002 drives the silicone plate 1003 to move upward until the silicone plate 1003 is tightly pressed against the lower surface of the right-angle support edge 501, thereby completing the installation of the threaded limiting cutting strip structure 10 and the right-angle support edge 501.

[0027] When the embodiment of the present application is in use, the staff first lays the film strip that has been cut and stripped flat on the support plate 6, and makes the lower end of the film strip pass through the strip winding and traction structure 4, then the staff takes out a plurality of threaded limiting cutting strip structures 10, and installs a plurality of threaded limiting cutting strip structures 10 on the right-angle support edge 501 in sequence. During this process, the staff can adjust the distance between two adjacent threaded limiting cutting strip structures 10, and the distance is the width of the film strip after subsequent cutting and stripping. After the threaded limiting cutting strip structure 10 is stably assembled with the right-angle support edge 501, the staff controls the cylinder 7 to work through the PLC control panel 9, and the cylinder 7 pulls the cross plate 5, the threaded limiting cutting strip structure 10 and other components to move toward the direction of the support plate 6. Until the blade part of the threaded limiting cutting strip structure 10 is pressed against the steel roller 8, at this time the film strip is located between the steel roller 8 and the threaded limiting cutting strip structure 10, and then the material strip winding and traction structure 4 is turned on again through the PLC control panel 9 to work, and the material strip winding and traction structure 4 actively conveys the film strip. During this process, the threaded limiting cutting strip structure 10 actively divides the film strip to obtain a film strip of a certain width. The cutting machine can realize flexible adjustment of the blade position through the structural design of the liftable cross plate 5, the right-angle support edge 501, and the threaded limiting cutting strip structure 10. This means that it is no longer limited to the fixed knife groove position, but the blade position and spacing can be adjusted at any time as needed, thereby improving the adaptability of the cutting machine to film strips of different specifications.
