Description

Technical Field

[0001] This invention belongs to the field of thin-film laser engraving technology, and particularly relates to a thin-film laser engraving processing equipment. Background Technology

[0002] Thin-film laser engraving equipment uses a laser beam to engrave, cut, or mark thin-film materials through non-contact processing. Its core advantages include high precision, high efficiency, and environmental friendliness, and it is widely used in fields such as microfluidic chips, flexible electronic devices, and packaging materials.

[0003] Patent CN107442945A discloses a thin-film laser engraving processing equipment, including a base, a laser engraving processing module, a feeding mechanism, and a discharging mechanism. The front end of the base is the feeding end, and the rear end is the discharging end. The feeding mechanism is located at the front end of the base; the discharging mechanism is located at the rear end of the base; a processing table is provided on the upper part of the base; the laser engraving processing module is mounted on the upper part of the base and has a laser engraving unit group, which is laterally distributed towards both sides of the base and located above the processing table; a feeding mechanism is provided below the laser engraving processing module to clamp the thin film on the processing table. The feeding mechanism is slidably mounted on the base and can move linearly towards either the discharging end or the feeding end of the base. Advantages: Simple structure, convenient operation; the laser engraving processing module does not move during use, and the thin film is conveyed and moved through the feeding mechanism, ensuring a stable laser processing optical path, higher processing efficiency, better processing quality, and convenient loading and unloading.

[0004] In existing technologies, by setting up a feeding structure, the entire device can achieve thin film conveying and movement, making the laser more stable. However, the following problems still exist during the overall use: Firstly, when existing engraving devices engrave films, if the temperature is too low, the film becomes more brittle, causing cracks to appear on the surface. If the temperature is too high, the film becomes more stretchable, leading to wrinkles. Existing devices cannot accurately control the temperature of the engraving area, resulting in a decrease in the engraving quality of the product. Secondly, existing engraving devices cannot discharge the engraved waste material after the film engraving is completed, which easily causes the film to accumulate. This causes the accumulated waste material to be cut again and float in the cutting area, affecting the engraving quality. Finally, when transporting the film, the existing engraving equipment is prone to causing wrinkles on the film surface due to the formation of a vacuum layer during transportation. At the same time, the film is prone to slippage due to the wrinkles during engraving, which affects the engraving quality of the film. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a thin-film laser engraving processing equipment. By incorporating temperature sensors and flow dividers, the temperature inside the engraving chamber can be adjusted, solving the problem that existing devices cannot accurately control the temperature of the engraving area, leading to a decline in product engraving quality. The installation of adjusting rollers and grooves allows for the flattening of the film, preventing loosening or wrinkling, while also providing heat dissipation for the adjusting rollers. Furthermore, the inclusion of a pulsed electrostatic removal device and a crushing roller pulverizes the separated waste material, addressing the technical problem of existing engraving devices failing to discharge the engraved waste after film engraving, leading to film accumulation. This accumulated waste is then re-cut, floating in the cutting area and affecting engraving quality.

[0007] Preferably, the bottom end face of the movable frame is provided with two pressure blocks, and the bottom end face of each of the two pressure blocks is provided with multiple downward protruding tooth blocks. The bottom of each of the two pressure blocks is provided with an abutment groove corresponding to the tooth blocks on the end face of the support platform.

[0008] Preferably, the outer surfaces of both pressing blocks are rotatably provided with limiting rollers, the two limiting rollers are slidably in contact with the film, and the lower surface of the two limiting rollers on the end face of the support platform is provided with a sink groove corresponding to the limiting roller.

[0009] Preferably, the inner wall of the movable frame is provided with two cleaning air chambers, and the bottom end face of each of the two cleaning air chambers is provided with an air outlet. Both air outlets face the limiting roller, and multiple air grooves are evenly provided below the two cleaning air chambers inside the sinking trough.

[0010] Preferably, the waste removal structure includes a sunken chamber disposed on the end face of the support platform, a crushing chamber disposed on the outer surface of the sunken chamber, a crushing roller disposed rotatably inside the crushing chamber, and a first filter plate disposed on one side of the crushing roller.

[0011] Preferably, the waste removal structure further includes a conveying pipe disposed outside the first filter plate, one end of the conveying pipe being provided with a storage box on the end face of the carving chamber, a blower being provided on one side of the storage box, and the air inlet of the blower being connected to the storage box through a first air pipe.

[0012] Preferably, a cleaning box is slidably disposed inside the storage box, and an air outlet is provided on one side wall of the cleaning box. Two mounting plates are provided on the side of the cleaning box with the air outlet. The two mounting plates are open, and a second filter plate is slidably disposed between the two mounting plates.

[0013] Preferably, the blower has an regulating chamber at its air outlet, a flow divider is provided inside the regulating chamber, two start-stop pumps are provided inside the flow divider, one end of each of the two start-stop pumps is provided with a flow divider pipe, one end of the two flow divider pipes is connected through a second air pipe, and one end of the second air pipe is slidably provided with a dehumidification chamber inside the regulating chamber, the dehumidification chamber is filled with dehumidifying particles.

[0014] Preferably, one of the diverter pipes has a copper pipe mounting component inside, and a copper pipe is provided on the outer surface of the copper pipe mounting component. A radiator is provided on one side of the copper pipe mounting component on the outer surface of the regulating chamber, and the radiator is connected to the copper pipe. A heating wire is arranged around the outer surface of the other diverter pipe, and a heating element is provided on one side of the heating wire on the outer surface of the regulating chamber.

[0015] Preferably, a temperature sensor is provided on the outer surface of the carving chamber, and a humidity sensor is provided on one side of the temperature sensor.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: This invention, by setting up a temperature sensor, a shunt pipe, a copper pipe mounting component, and a heating wire, can monitor the temperature inside the engraving chamber in real time, thus facilitating temperature adjustment. At the same time, the copper pipe mounting component and the heating wire heat and cool the air transported in the pipe, thereby controlling the temperature inside the engraving chamber and improving the molding quality of the film. Furthermore, by setting up a pulse electrostatic removal device, static electricity on the surface of the film can be removed, further improving the engraving quality of the film. This invention incorporates structures such as an adjusting roller, grooves, pressure blocks, and limiting rollers. The film is wound around the outer surface of the adjusting roller, and the other end of the film is fixed to the outer surface of the take-up roller. Rotating the adjusting roller can stretch the film, preventing it from loosening or wrinkling. The grooves allow for heat dissipation from the adjusting roller during film transport, preventing heat generated by friction between the film and the adjusting roller from causing white marks on the film surface. The movable frame and pressure blocks hold the film against the end face of the support platform for fixation. The pressure blocks leave grooves on the surface of the film, facilitating the subsequent removal of the engraved film. This invention, by setting up a cleaning air chamber, a limiting roller, a movable frame, and an air groove, allows the airflow entering the engraving chamber to first contact the limiting roller and clean its outer surface. Then, the airflow blows air onto the surface of the film through the air groove at the bottom of the limiting roller, blowing air from both ends of the film towards the middle, which facilitates the separation of the engraved film from waste and improves the efficiency of waste discharge. This invention, by setting up a pulse electrostatic removal device, a filter plate, a storage box, and a filter plate, can crush the separated waste material and collect it inside the storage box through a conveying pipe for unified processing, reducing cleaning difficulty. The filter plate can filter impurities, and the filter plate is slidably connected to one side of the cleaning box for easy replacement, improving maintenance efficiency. Attached Figure Description

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1: refer to Figure 1 , Figure 4 and Figure 5 A thin-film laser engraving processing device includes an engraving machine tool 10. A transport roller 11 is rotatably mounted on the end face of the engraving machine tool 10 via a bracket. A support roller 12 is rotatably mounted on one side of the transport roller 11 via a bracket on the end face of the engraving machine tool 10. A take-up roller 13 is rotatably mounted on one side of the support roller 12 via a bracket on the end face of the engraving machine tool 10. A support platform 50 is provided between the support roller 12 and the take-up roller 13. An engraving chamber 14 is provided on the end face of the support platform 50. The film is drawn out from the transport roller 11, wrapped around the outer surface of the support roller 12, and then passes through the engraving chamber 14 and the support platform 50. Two feeding ports 32 are provided on the bottom end face of the engraving chamber 14. The film passes through the interior of the engraving chamber 14 through the feeding ports 32, and then extends out through the other feeding port 32 and is wrapped and fixed on the outer surface of the take-up roller 13.

[0020] Further reference Figure 1 , Figure 2 , Figure 3 and Figure 10The engraving chamber 14 has a movable frame 20 that can fix the film inside. A drive cylinder 24 is provided on the end face of the engraving chamber 14. The output shaft of the drive cylinder 24 passes through the top end face of the engraving chamber 14 and is fixedly connected to the movable frame 20. Two pressure blocks 27 are provided on the bottom end face of the movable frame 20. The two 27 are located above the two feeding ports 32. The bottom end face of the two pressure blocks 27 is provided with multiple downward protruding tooth blocks 54. The bottom of each tooth block 54 is trapezoidal. The bottom of the two pressure blocks 27 is provided with abutment grooves 53 corresponding to the tooth blocks 54 on the end face of the support platform 50. The bottom end face of the movable frame 20 is provided with two slide rails 23. Sliding blocks are slidably provided on the outer surface of the two slide rails 23. A laser engraving device 21 for laser engraving is provided on the bottom end face of the sliding blocks. Before laser engraving the film, the drive cylinder 24 is activated. The output end of the drive cylinder 24 moves downward and pushes the movable frame 20 downward. During the movement of the movable frame 20, the two pressure blocks 27 at the bottom move downward. While the pressure blocks 27 are moving, they also drive multiple toothed blocks 54 on the bottom end face to move up and down. When the toothed blocks 54 move, they first contact the film, and as the pressure blocks 27 continue to move, the toothed blocks 54 press the film against the inside of the abutment groove 53, thereby fixing the film. The toothed blocks 54 leave indentations on the surface of the film when pressing it, thus forming two rows of tooth marks on the surface of the film. The area between the two rows of tooth marks is the engraving area. This setting facilitates the subsequent removal of the engraved area and the separation of the engraved area from the film body, thereby improving work efficiency. When engraving the film, the sliding block is activated by the control terminal. The sliding block moves along the slide rail 23 and drives the laser engraving device 21 to move. At the same time, the laser engraving device 21 is activated, so that the laser engraving device 21 engraves the film.

[0021] Further reference Figure 4 , Figure 5 and Figure 6 Both pressure blocks 27 have rotatable limit rollers 26 on their outer surfaces. Both limit rollers 26 slide against the film. Below the two limit rollers 26, on the end face of the support platform 50, there is a sinking groove 30 corresponding to the limit rollers 26. The inner wall of the movable frame 20 has two cleaning air chambers 25. The bottom end face of the two cleaning air chambers 25 has an air outlet. Both air outlets face the limit rollers 26. When the movable frame 20 moves downward, it will drive the two limit rollers 26 to move downward synchronously, so that the limit rollers 26 abut the film against the outer surface of the sinking groove 30, thereby further fixing the film.

[0022] Further reference Figure 1 , Figure 2 and Figure 3A sinking chamber 33 is provided on the end face of the support platform 50. A crushing chamber 34 is provided on the outer surface of the sinking chamber 33. A crushing roller 35 is rotatably installed inside the crushing chamber 34. A first filter plate 36 is provided on one side of the crushing roller 35. A conveying pipe 37 is provided on the outer surface of the first filter plate 36. A storage box 38 is provided at one end of the conveying pipe 37 on the end face of the engraving chamber 14. A blower 17 is provided on one side of the storage box 38. The air inlet of the blower 17 is connected to the storage box 38 through a first air pipe. Waste generated by laser engraving will be discharged through the blower 38. The material falls into the lower chamber 33 due to gravity. At this time, the blower 17 is started to draw air from the lower chamber 33 and simultaneously suck up the waste material inside the lower chamber 33, causing the waste material inside the lower chamber 33 to enter the crushing chamber 34. At this time, the crushing roller 35 is started to crush the waste material. The crushed waste material is filtered by the first filter plate 36 and formed into a uniform size. Then, it enters the storage box 38 through the conveying pipe 37 for storage, so as to facilitate subsequent unified cleaning and improve cleaning efficiency.

[0023] Further reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The storage box 38 has a cleaning box 39 that slides inside. Two handles are provided on the end face of the cleaning box 39. This facilitates the removal of waste materials as a whole, improving cleaning efficiency. One side wall of the cleaning box 39 has an air outlet. Two mounting plates 51 are provided on the side with the air outlet. The two mounting plates 51 are open, and a second filter plate 40 is slidably disposed between the two mounting plates 51. This arrangement facilitates the removal, replacement, and maintenance of the second filter plate 40. The blower 17 has an regulating chamber 18 at its air outlet. A flow divider plate 41 is provided inside the regulating chamber 18. Two start-stop pumps 42 are installed inside the flow divider plate 41. Each of the two start-stop pumps 42 has a flow divider pipe 52 at one end. One end is connected via a second air pipe. A dehumidification chamber 48 is slidably installed inside the regulating chamber 18 at one end of the second air pipe. The dehumidification chamber 48 is filled with dehumidifying particles. A temperature sensor 28 is installed on the outer surface of the carving chamber 14. A humidity sensor 29 is installed on one side of the temperature sensor 28. The temperature sensor 28 can monitor the internal temperature of the carving chamber 14. A copper pipe mounting component 43 is installed inside one of the diversion pipes 52. A copper pipe is installed on the outer surface of the copper pipe mounting component 43. A radiator 44 is installed on one side of the copper pipe mounting component 43 on the outer surface of the regulating chamber 18. The radiator 44 is connected to the copper pipe. An electric heating wire 45 is arranged around the outer surface of the other diversion pipe 52. A heating element 46 is installed on one side of the electric heating wire 45 on the outer surface of the regulating chamber 18.

[0024] When the temperature inside the carving chamber 14 is too low, one of the start-stop pumps 42 and the heating element 46 are activated. The heating element 46 heats the heating wire 45, which in turn heats one of the diversion pipes 52. The air entering the regulating chamber 18 experiences a temperature increase as it passes through the heated diversion pipe 52. The heated air then passes through the dehumidification chamber 48 for dehumidification. The hotter, drier air is then transported into the carving chamber 14 through the connecting air pipe 49, thereby increasing the temperature inside the carving chamber 14. The humidity sensor 29 monitors the humidity inside the carving chamber 14. When the humidity inside the carving chamber 14 is too high, an alarm is sent to the control terminal to facilitate timely replacement of the dehumidifying particles inside the dehumidification chamber 48, ensuring the stable operation of the device. When the temperature sensor 28 detects that the temperature of the carving chamber 14 is too high, another start-stop pump 42 is activated. Air enters the interior of the diversion pipe 52 through the start-stop pump 42. At this time, the radiator 44 is activated, and the radiator 44 injects coolant into the interior of the copper pipe mounting component 43, so that the copper pipe mounting component 43 cools the air passing through the start-stop pump 42. After being dried by the dehumidification chamber 48, the cooled air is reinjected into the interior of the carving chamber 14 through the connecting air pipe 49 to form a circulation and reduce the temperature inside the carving chamber 14.

[0025] Further reference Figure 4 , Figure 5 and Figure 6 The outer surface of the engraving chamber 14 is provided with a connecting air chamber 19. One end of the connecting air pipe 49 is connected to the connecting air chamber 19. The connecting air chamber 19 is connected to the interior of the cleaning air chamber 25 through a telescopic hose, providing an air source to the interior of the cleaning air chamber 25. The temperature-adjusted air is injected into the interior of the engraving chamber 14 through the cleaning air chamber 25. The adjusted air contacts the limiting roller 26 through the air outlet at the bottom of the cleaning air chamber 25, so that the airflow cleans the outer surface of the limiting roller 26. At the same time, the limiting roller 26 can buffer the airflow to prevent the high-pressure airflow from breaking through the indentation of the film and improve the integrity of the film. Some of the airflow flows to the middle section, so that the cut film is separated from the waste material. The waste material is pushed into the interior of the sinking chamber 33 for discharge. Below the two cleaning air chambers 25, in the interior of the sinking trough 30, there is an air groove 31. By setting the air groove 31, when the cleaning air chamber 25 delivers gas downward, the gas contacts the film, so that the film bends into the interior of the air groove 31, which facilitates the separation of the cut part from the film as a whole and improves the discharge efficiency.

[0026] Example 2: refer to Figure 1-2A thin-film laser engraving processing device includes an adjusting roller 15 rotatably mounted on the outer surface of an engraving chamber 14, supported by a bracket. The outer surface of the adjusting roller 15 has multiple grooves 16. A second motor is mounted on one side of the adjusting roller 15, and a first transmission wheel is installed at the output end of the second motor. A second transmission wheel is mounted on one side of the first transmission wheel on the outer surface of the adjusting roller 15. The first and second transmission wheels are connected by a chain drive. During the transport of the film, the high-speed rotation of the adjusting roller 15 creates a vacuum gap between the adjusting roller 15 and the film, causing wrinkles and creases. By setting grooves 16 on the surface of the adjusting roller 15 and causing it to rotate towards a transport roller 11, and because one end of the film is fixed by a take-up roller 13, the adjusting roller 15 can not only adjust the tightness of the film during rotation but also expel air through the grooves 16, improving the stability of the film. Furthermore, the grooves 16 help the adjusting roller 15 dissipate heat during film transport, preventing heat buildup and softening of the film, thereby improving the quality of the film.
