Description

Technical Field

[0002] As a core consumable for garment heat transfer printing, bag labeling, and cultural and creative accessory processing, laser engraving, marking, and slitting are the mainstream production processes in the industry. Currently, the industry mostly uses a semi-automatic single-machine combined with manual assistance to complete this process. As the industry continues to raise its requirements for processing efficiency, product yield, and production standardization, many technical shortcomings of existing traditional processing equipment and processes are gradually becoming apparent.

[0003] Existing processing equipment is mostly single-function machines, with feeding, laser processing, slitting, and winding processes operating independently. This requires manual transfer of film material in segments and connection between processes, resulting in a high degree of reliance on manual labor throughout the entire process. It is impossible to achieve continuous operation, and the processing cycle for a single batch is long, making it difficult to meet the needs of large-scale mass production. In addition, manual operation is prone to causing sequence disorder, and there is a lack of precise defective cutting and removal mechanisms for finished lettering films. Defective film material cannot be accurately located and removed, and most of it can only be discarded in whole segments or rolls, resulting in extremely low raw material utilization and serious waste.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This implementation example Figures 1-10 As shown, a fully automatic laser coordinated processing equipment for lettering film includes a laser cutting host 1 and a mesh conveyor belt 3, a laser processing unit, an automatic feeding system, an automatic winding mechanism, a slitting processing unit, a splicing unit, and a control system. The mesh conveyor belt 3 is located in the middle of the laser cutting host 1. An automatic feeding system is installed at one end of the laser cutting host 1 to realize the feeding, leveling and tension adjustment of the lettering film roll; The laser processing unit is located at the top inside of the laser cutting host 1 and is used to burn or mark the lettering film roll. An automatic winding mechanism is installed at the other end of the laser cutting host 1 to wind up the abrasive after the waste film is removed; The slitting and processing unit is located between the mesh conveyor belt 3 and the automatic winding mechanism, and is used to cut off defective products in the lettering film rolls; The splicing unit is located at the end of the slitting unit and is used to splice the two sections of lettering film rolls processed by the slitting unit. The control system is electrically connected to the automatic feeding system, laser processing unit, slitting processing unit, splicing unit, and automatic winding mechanism to coordinate the action sequence and parameters of each unit, thereby achieving fully automated and coordinated processing.

[0021] In this scheme, the equipment takes the laser cutting host 1 as the core carrier, the mesh conveyor belt 3 is horizontally set in the middle of the laser cutting host 1, and the automatic winding mechanism is installed at the end of the laser cutting host 1, which is connected to the slitting and splicing unit. The control system is electrically connected to all the above functional units. The control system uniformly controls the start, operation and stop sequence of each unit. At the same time, it can preset processing parameters, monitor the equipment operation status in real time, and perform statistical analysis on production processing data to realize intelligent management and control of the equipment.

[0022] Furthermore, the automatic feeding system includes a leveling conveyor roller 4, a base 5, and a guide rod 6. The base 5 is fixedly installed on the outer extension of the long plate on the side of the laser cutting host 1 by a long rod. The leveling conveyor roller 4 is set on the inner side of the long plate on the side of the laser cutting host 1, and the guide rod 6 is set on the outer extension of the long plate on the side of the laser cutting host 1.

[0023] In this scheme, the automatic feeding system is installed at the feeding end of the laser cutting host 1. The core of the system is to realize the feeding, leveling and tension adjustment of the lettering film roll, so as to provide a flat and stable film material foundation for subsequent laser processing. The base 5 is fixedly installed on the outer extension of the long plate on the side of the laser cutting host 1 by a long rod, which serves as the support foundation of the automatic feeding system and ensures the stability of the feeding structure. The lettering film roll is sleeved on the sleeve rod of the base 5, and the continuous feeding of the lettering film roll is realized by the conveying of the leveling conveying roller 4. The leveling conveyor roller 4 is set on the inner side of the long plate on the side of the laser cutting host 1 and is connected to the feed end of the mesh conveyor belt 3. When the lettering film roll passes through the leveling conveyor roller 4, the film is flattened by the squeezing and rolling of the roller body, eliminating the wrinkles and warping caused by the film roll. The guide rod 6 is also set on the outer extension of the long plate on the side of the laser cutting host 1, located between the unwinding end of the roll and the leveling conveyor roller 4, to guide the roll. At the same time, the tension of the film material can be adjusted by adjusting the position of the guide rod 6 to avoid the film material from loosening or being overstretched.

[0024] Furthermore, the laser processing unit includes a smoke extraction port 2, a laser generator, a galvanometer scanning system, and a focusing lens. The smoke extraction port 2 is located on the front of the laser cutting host 1 and is connected to an external exhaust pipe. The laser generator, galvanometer scanning system, and focusing lens are integrated in the laser box on the top of the laser cutting host 1.

[0025] In this solution, the laser generator, galvanometer scanning system, and focusing lens are integrated in the laser box on top of the laser cutting host 1. The laser beam generated by the laser generator is adjusted by the galvanometer scanning system and focused by the focusing lens, and then precisely applied to the surface of the lettering film on the mesh conveyor belt 3 to achieve engraving and marking processing. The galvanometer scanning system can achieve rapid and accurate positioning of the laser beam to ensure the accuracy of the processed pattern. The galvanometer scanning system is a known device in this technical field, and it can be used in conjunction with this device to process the surface of the lettering film without specifically disclosing its specific structure. The smoke inlet 2 is located on the front of the laser cutting host 1 and is connected to an external exhaust pipe. During the laser processing, smoke and odors will be generated. The smoke inlet 2 can draw the smoke from the processing area into the exhaust pipe and discharge it in real time, keeping the processing environment clean and preventing smoke from adhering to the laser lens and the surface of the lettering film, thus affecting the processing quality.

[0026] Furthermore, the automatic winding mechanism includes a pressure roller cylinder 16, a pair of pressure rollers 17, a waste film roller 8, and a take-up roller 9. The pressure roller cylinder 16 is located inside the laser cutting host 1 and near one end of the mesh conveyor belt 3. A bracket 7 is provided on the side plate extension of the laser cutting host 1. A light inspection table 19 is provided on the inner side of the bracket 7. The light inspection table 19 is located directly above the slitting processing unit. The pair of pressure rollers 17 is located inside the pressure roller cylinder 16. The waste film roller 8 is located on the top of the bracket 7. The take-up roller 9 is located on the inner side of the side plate extension of the laser cutting host 1, with the waste film roller 8 located above the take-up roller 9. A film guide opening 20 is provided on the outer side of the pressure roller cylinder 16, and the pair of pressure rollers 17 are symmetrically arranged about the film guide opening 20.

[0027] In this scheme, the bracket 7 is fixed to the side plate extension of the laser cutting host 1, providing installation support for the waste film roller 8 and the optical inspection table 19. The optical inspection table 19 is set inside the bracket 7 and is located directly above the slitting processing unit. It can perform visual inspection on the lettering film before slitting, identify the defective areas of the film material, and provide positioning basis for slitting processing. The optical inspection table 19 performs full-width visual inspection on the film material according to preset parameters, identifies defective areas on the film material in real time, such as missing printing or incomplete pattern offset, and transmits the position and size data of the defective products to the control system in real time. The control system completes precise positioning. If the film material is found to be qualified, it is directly conveyed to the winding roller 9 for winding.

[0028] The pressure roller 16 is located inside the laser cutting host 1 and near the discharge end of the mesh conveyor belt 3. A guide film opening 20 is provided on its outer side. The engraved film passes through the guide film opening 20 into the pressure roller 16. The pressure roller group 17 is symmetrically arranged inside the pressure roller 16 about the guide film opening 20. The film material passes between the two groups of pressure rollers 17. The film material is clamped and conveyed by the pressure of the rollers, ensuring the stability of the conveying. At the same time, the finished product after the waste film is torn off is compacted again. Waste film roller 8 is located on top of bracket 7, and take-up roller 9 is located inside the side extension of the laser cutting host 1, with waste film roller 8 positioned above take-up roller 9. Waste film generated by laser processing is guided and wound onto waste film roller 8 to complete winding. Finished film material after removing waste film is conveyed to take-up roller 9 for regular winding, achieving separation and winding of waste film and finished film material. It should be noted that the waste film generated by laser processing is guided and wound onto waste film roller 8 to complete winding, and the waste film head needs to be manually wound onto waste film roller 8. Similarly, the film head of finished film material is manually wound onto the outside of take-up roller 9. Both take-up roller 9 and waste film roller 8 are driven by motors and their operation is controlled by the control system.

[0029] Furthermore, the slitting processing unit includes a slitting table 10, a guide protrusion 18, a linear guide rail 12, and a pneumatic telescopic rod 11. The slitting table 10 is located inside the side plate extension of the laser cutting host 1. The guide protrusion 18 is located on the inner bottom wall of the slitting table 10. The pneumatic telescopic rod 11 is located at the inner bottom of the slitting table 10. The bottom of the linear guide rail 12 is located at the output end of the pneumatic telescopic rod 11.

[0030] The slitting processing unit also includes a linear slide 25, a slider 24, a ball sleeve 23, and a transverse cutting blade 26. The linear slide 25 is symmetrically opened on the upper and lower surfaces of the linear guide rail 12. The slider 24 is snapped and movably disposed on the inner wall of the linear slide 25. The ball sleeve 23 is disposed on the outer side of one of the sliders 24. The transverse cutting blade 26 is fixedly disposed at the bottom end of the slider 24. The slitting processing unit also includes a stepper motor 30, a lead screw 22, a pneumatic stamping cylinder 29, a longitudinal cutting blade 28, and a photoelectric limit switch 31. The stepper motor 30 is fixedly mounted on the outside of the linear guide rail 12. The lead screw 22 is mounted on the output end of the stepper motor 30 and is sleeved on the ball sleeve 23. The pneumatic stamping cylinder 29 is fixedly mounted on the end face of the slider 24. The longitudinal cutting blade 28 is movably mounted on the output end of the pneumatic stamping cylinder 29. The longitudinal cutting blade 28 and the transverse cutting blade 26 are arranged perpendicular to each other. The photoelectric limit switch 31 is mounted on the side of the linear guide rail 12.

[0031] In this scheme, when the control system receives the defective product positioning data from the optical inspection station 19, it immediately triggers the action of the slitting and processing unit: the pneumatic telescopic rod 11 drives the linear guide rail 12 to descend to the preset height, so that the cutting tool is close to the film material; the stepper motor 30 drives the lead screw 22 to rotate, and under the action of the ball sleeve 23, it drives the slider 24 to perform strip cutting on the finished film material along the straight groove 25. The slitting table 10 is located inside the side plate extension of the laser cutting host 1, serving as a slitting platform. A guide protrusion 18 is located on the inner bottom wall of the slitting table 10 to guide and limit the lettering film, preventing it from shifting during the slitting process. A pneumatic telescopic rod 11 is located at the inner bottom of the slitting table 10. The bottom of the linear guide rail 12 is connected to the output end of the pneumatic telescopic rod 11. The pneumatic telescopic rod 11 can drive the linear guide rail 12 to move up and down, adjusting the distance between the cutting tool and the film. To adapt to the slitting requirements of lettering films of different thicknesses, straight grooves 25 are symmetrically opened on the upper and lower surfaces of the guide rail 12. Slider 24 is engaged and can slide along the inner wall of the straight groove 25. Ball sleeve 23 is set on the outside of one set of sliders 24. The transverse cutting blade 26 is fixedly set at the bottom of the slider 24. With the sliding of the slider 24, the transverse cutting operation along the film material is realized. Under the drive of the lead screw 22, the ball sleeve 23 drives the slider 24 to make linear motion, further ensuring the smoothness of the slider 24.

[0032] Stepper motor 30 drives lead screw 22 to rotate, causing ball sleeve 23 and slider 24 to move along linear groove 25. Slider 24 moves laterally along linear groove 25 to achieve precise adjustment of cutting position. The transverse cutting blade 26 is set in parallel. When slider 24 moves in a straight line, transverse cutting blade 26 performs strip cutting on the defective area of ​​finished film. Pneumatic stamping cylinder 29 is fixedly set on the end face of slider 24. Longitudinal cutting blade 28 is movably set on the output end of pneumatic stamping cylinder 29. Longitudinal cutting blade 28 and transverse cutting blade 26 are set perpendicular to each other. Pneumatic stamping cylinder 29 drives longitudinal cutting blade 28 to perform telescopic movement to achieve longitudinal cutting of film material. Transverse cutting blade 26 and longitudinal cutting blade 28 cooperate to achieve precise removal of square, rectangular and other regular shapes of defective areas of film material. Camera 27 is set on the inner top wall of slider 24. Camera 27 is used to take pictures and record defective areas of film material and is connected to an external PC.

[0033] In one of the optional embodiments of this solution, when the slider 24 moves in a straight line, the transverse cutting blade 26 performs strip cutting on the finished film. The positioning of the slider 24 can be achieved by the cooperation of the drive screw 22 and the ball sleeve 23. Then, the pneumatic stamping cylinder 29 drives the longitudinal cutting blade 28 to perform telescopic movement to achieve longitudinal cutting of the film material, which can realize the rectangular sheet cutting of the finished film material.

[0034] The photoelectric limit switch 31 is set on the side of the linear guide rail 12 to limit the sliding stroke of the slider 24, preventing the slider 24 from sliding beyond its stroke and causing damage to the cutting structure or deviation in the cutting position. At the same time, it works with the stepper motor 30 to achieve precise positioning of the cutting position and ensure cutting accuracy.

[0035] Furthermore, the splicing unit includes a hot press table 14, a splicing table 15, a film outlet 13, and a splicing interface 21. The hot press table 14 is movably disposed on the top of the slitting table 10. The film outlet 13 is opened at one end of the slitting table 10. The splicing interface 21 is opened on the bottom surface of the slitting table 10 and is located near the film outlet 13. The splicing table 15 is disposed on the bottom surface of the slitting table 10 and is located around the splicing interface 21. The control system adopts an industrial computer and PLC architecture, and supports parameter preset, fault alarm and production data statistics.

[0036] In this scheme, after the two sections of qualified film material are conveyed to the splicing unit, the control system triggers the splicing action. The mating ends of the film material are precisely inserted into the splicing interface 21 through the film outlet 13 to complete the alignment and positioning. The hot press table 14 moves downward according to the preset parameters to hot press and bond the mating ends of the film material in the splicing interface 21. After the pressure is maintained, the hot press table 14 is reset to achieve seamless splicing of the two sections of film material. The complete finished film material after splicing is conveyed to the take-up roller 9 of the automatic winding mechanism. The film outlet 13 is located at one end of the slitting table 10. The two sections of lettering film after slitting are conveyed to the splicing operation area through the film outlet 13. The splicing interface 21 is located on the bottom surface of the slitting table 10 and close to the film outlet 13. The joint ends of the two sections of lettering film extend into the splicing interface 21 to achieve joint positioning and ensure the alignment of the splicing. The hot press table 14 is movably set on the top of the slitting table 10, corresponding to the position of the splicing interface 21. The hot press table 14 can move downward and perform hot pressing on the joint ends of the film material in the splicing interface 21. Seamless splicing of the two sections of film material is achieved through hot pressing and bonding. After splicing, the film material is conveyed to the automatic winding mechanism for winding.

[0037] The execution of the above actions is achieved by using a PLC-programmed control system and a PC to precisely control the timing of each functional unit, thus realizing continuous automated operation of feeding, laser processing, detection, slitting, splicing, and winding.

[0038] A fully automated laser coordination process for lettering film includes the following steps: 1. The roll of lettering film to be processed is installed in the automatic feeding system. The roll is pulled through the laser processing unit, the dividing processing unit, and the splicing unit in sequence, and finally wound onto the automatic winding mechanism. II. Based on the material of the lettering film and processing requirements, preset the laser processing parameters and divide them into cutting processing unit and splicing unit parameters; 3. Start the equipment and control system to coordinate the synchronous operation of each unit to complete the conveying, laser processing, automatic waste removal, automatic detection, finished product slitting and finished product winding of the lettering film roll; 4. After processing is completed, remove the finished roll material to complete batch processing.
