[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-4 As shown, this utility model provides a technical solution: a multi-specification cutting device for producing automotive interior fabrics, including a workbench 1, a robotic arm device 11 fixedly installed on the top of the workbench 1, and a cutting tool 12 provided at the working end of the robotic arm device 11, and further including:

[0031] Fabric positioning mechanism 2 is set on the top of workbench 1 and is used to adsorb and fix the fabric.

[0032] Fabric flattening mechanism 3 is set on the top of workbench 1. Fabric flattening mechanism 3 is used to press down and flatten the fabric on fabric positioning mechanism 2.

[0033] The fabric positioning mechanism 2 includes an adsorption positioning component and an air filtration component. The adsorption positioning component includes a hollow base 21 and an air pump 26. The hollow base 21 is fixedly installed on the top of the workbench 1. A cover plate 22 is movably inserted into the top of the hollow base 21. A round hole 23 is opened on the top of the cover plate 22. A through hole 24 is opened on the left side of the hollow base 21. A connecting pipe 25 is fixedly connected to the left side of the hollow base 21. The air pump 26 is fixedly installed on the top of the workbench 1. The air inlet end of the air pump 26 is connected to the connecting pipe 25. The top of the tube 25 is fixedly connected. First, the fabric is laid flat on the top of the cover plate 22. Then, the suction pump 26 can be controlled to work, drawing gas from the inner cavity of the cover plate 22 through the connecting tube 25 and the through hole 24. Then, air is drawn in through the round hole 23. The negative pressure generated by the round hole 23 can adsorb and fix the fabric to the top of the cover plate 22, improving the fixing efficiency of irregular fabrics. The suction pump 26 is controlled to be turned off, and the fabric can be removed from the top of the cover plate 22, improving the removal efficiency of the fabric.

[0034] As one implementation method in this embodiment, such as Figure 2 As shown, a protrusion 221 is fixedly installed on the outer wall of the cover plate 22, and a connecting bolt 222 is threaded onto the protrusion 221. The threaded end of the connecting bolt 222 is movably connected to the outer wall of the hollow seat 21. A gripping rod 223 is fixedly installed on the outer wall of the protrusion 221. In the initial state, the connecting bolt 222 is tightened, and its threaded end is attached to the outer wall of the hollow seat 21, locking the cover plate 22 on the top of the hollow seat 21. If the cover plate 22 needs to be disassembled and cleaned, loosen the connecting bolt 222, then grasp the gripping rod 223 and pull the cover plate 22 out from the top of the hollow seat 21. To reset, insert the cover plate 22 into the top of the hollow seat 21 and then tighten the connecting bolt 222.

[0035] As one implementation method in this embodiment, such as Figure 3As shown, the air filter assembly includes a fixed block 211 and a movable plate 212. The fixed block 211 is fixedly installed on the inner wall of the hollow base 21, and the movable plate 212 is detachably connected to the inner wall of the hollow base 21. An air filter screen 213 is fixedly installed on the inner wall of the movable plate 212. Through the design of the air filter screen 213, the air absorbed by the air pump 26 can be filtered to avoid the problem that debris can easily damage the air pump 26 and extend its service life. If the air filter screen 213 needs to be cleaned, after the cover plate 22 is removed, the bolts on the movable plate 212 are loosened, and the movable plate 212 can be disassembled to facilitate the cleaning of the air filter screen 213.

[0036] As one implementation method in this embodiment, such as Figure 4 As shown, the fabric flattening mechanism 3 includes a support frame 31, which is fixedly installed on the top of the workbench 1. A lead screw 32 is rotatably connected to the inner wall of the support frame 31, and a track rod 33 is fixedly installed on the inner wall of the support frame 31. A servo motor 34 is fixedly installed on the front of the support frame 31, and the output shaft of the servo motor 34 is fixedly connected to the end of the lead screw 32. A sliding seat 35 is slidably connected to the outer wall of the lead screw 32 and the track rod 33. By controlling the servo motor 34 to work, the lead screw 32 can be rotated, which in turn can drive the sliding seat 35 to slide on the outer wall of the track rod 33 to adjust its front and rear positions.

[0037] As one implementation method in this embodiment, such as Figure 4 As shown, a column 36 is fixedly installed on the top of the sliding seat 35, a top plate 361 is fixedly installed on the top of the column 36, an elastic element 362 is fixedly installed on the bottom of the top plate 361, a vertical slider 363 is fixedly installed on the bottom of the elastic element 362, the vertical slider 363 is slidably connected to the outer wall of the column 36, a pull handle 364 is fixedly installed on the top of the vertical slider 363, and a pressure roller 365 is rotatably connected to the left side of the vertical slider 363. The vertical slider 363 is pre-pulled upward from the pull handle 364, causing the vertical slider 363 to move upward on the outer wall of the column 36. The sliding mechanism compresses the elastic element 362, and then the servo motor 34 is controlled to adjust the overall position of the sliding seat 35, positioning the pressure roller 365 above the fabric. Next, the pull handle 364 is released, and the restoring force of the elastic element 362 causes the pressure roller 365 to move downwards, pressing it firmly against the top of the fabric. Then, the servo motor 34 is controlled to operate, causing the sliding seat 35 to slide back and forth, allowing the pressure roller 365 to slide back and forth on the top of the fabric, pressing it down to flatten it and eliminate wrinkles that could affect the cutting process, thus improving the quality of the cut.

[0038] Working principle: In use, first lay the fabric flat on the top of the cover plate 22. If the fabric needs to be flattened, pull the vertical slider 363 upward from the handle 364. Then control the servo motor 34 to adjust the overall position of the sliding seat 35, and adjust the pressure roller 365 above the fabric. Then release the handle 364. Through the reset force of the elastic element 362, the pressure roller 365 is driven to stick tightly to the top of the fabric. Then the servo motor 34 can be controlled to work, driving the sliding seat 35 to slide back and forth, so that the pressure roller 365 slides back and forth on the top of the fabric to flatten the fabric. Then the suction pump 26 can be controlled to work, drawing gas from the inner cavity of the cover plate 22 through the connecting pipe 25 and the through hole 24, and then absorbing air through the round hole 23. The negative pressure generated by the round hole 23 can adsorb and fix the fabric to the top of the cover plate 22. Then the robotic arm device 11 can be controlled to work, driving the cutting tool 12 to cut the fabric.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
