Description

Technical Field

[0001] This utility model relates to the field of laser cutting devices, and in particular to a reflective film laser cutting device with dust collection function. Background Technology

[0002] Reflective films are functional thin-film materials used in optical equipment and precision instruments. They reflect light and are widely used in displays, anti-glare devices, and optical lenses. To meet the light transmission requirements of reflective films, they need to be laser-cut and perforated. The laser cutting machine uses a laser beam to partially melt or vaporize the reflective film to obtain a hole structure with precise dimensions and smooth edges. These holes are used to improve the light transmission performance of the reflective film and facilitate its installation and fixation.

[0003] In existing technologies, the laser drilling process for reflective films involves high-temperature melting and vaporization, generating a large amount of smoke and dust, as well as tiny film fragments. Due to their thinness and electrostatic adsorption, these fragments easily adhere to the cutting area and equipment surface, increasing the difficulty of cleaning. The accumulation of these fragments not only affects the dimensional accuracy of the holes and the smoothness of the cut surface but also affects the normal operation of the equipment, increasing maintenance costs. Furthermore, if the smoke and dust generated during the cutting process are not effectively removed, it will reduce the cleanliness of the processing environment, thus adversely affecting the health of the operators.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0015] The top of the hollow cavity seat is provided with an air inlet that communicates with the annular chamber, and the air inlet is used to provide high-pressure airflow to the annular chamber.

[0016] In the aforementioned technical solution, the air outlet of the nozzle is inclined downwards in the laser cutting device for reflective film with dust collection function, and the central axes of the air outlets of multiple nozzles converge and intersect on the central axis of the annular dust collection hood.

[0017] Using the above technical solution, in the laser cutting device for reflective film with dust collection function, a waste collection box is provided at the bottom of the film adsorption plate, and the waste collection box is used to collect film waste generated during the laser cutting process.

[0018] Using the above technical solution, in the laser cutting device for reflective film with dust collection function, the side wall of the waste collection box is provided with a suction pipe, which is used to generate a suction force.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 7As shown in the figure, this utility model embodiment provides a reflective film laser cutting device with dust collection function, including a base 1, a dual-axis moving mechanism 2, a film adsorption plate 3, a mounting plate 4, a laser cutting head 5, a fume hood 6, and a lifting and dust collection mechanism 7. The film adsorption plate 3 is disposed in the base 1 and is used to adsorb and fix the reflective film to be laser cut. The dual-axis moving mechanism 2 is disposed above the film adsorption plate 3, and its movable end is connected to the mounting plate 4. The dual-axis moving mechanism 2 is used to drive the mounting plate 4 to move in the X-axis and Y-axis directions. The reflective film is firmly adsorbed on the film adsorption plate 3. The laser cutting head 5 can move on the surface of the film according to a set path and cut through the action of the dual-axis moving mechanism 2, thereby meeting the cutting and processing requirements of complex shapes.

[0037] The laser cutting head 5 is mounted on the mounting plate 4. The laser cutting head 5 is used to emit a laser beam toward the reflective film on the film adsorption plate 3. The fume hood 6 is mounted on the mounting plate 4 on the back of the laser cutting head 5. The fume hood 6 is used to adsorb the smoke and dust generated by the laser cutting head 5 during laser cutting. The laser cutting head 5 can locally heat the film with a high-energy laser beam, causing it to melt or vaporize rapidly, thereby forming a cutting or drilling operation on the reflective film. At the same time, the fume hood 6 can collect the smoke and dust generated during laser processing through adsorption, preventing the smoke and dust from spreading and affecting the working environment.

[0038] like Figure 2 and Figure 3 As shown, the lifting and dust collection mechanism 7 is located on the side of the laser cutting head 5. The lifting and dust collection mechanism 7 includes a lifting cylinder 71, a slide rail assembly 72, a lifting seat 73, and an annular dust collection hood 74. The lifting cylinder 71 is located on the mounting plate 4, with its movable end facing downwards and connected to the lifting seat 73. The lifting seat 73 is movably connected to the mounting plate 4 via the slide rail assembly 72. The lifting cylinder 71 is used to adjust the height between the lifting seat 73 and the membrane adsorption plate 3. The annular dust collection hood 74 is located at the bottom of the lifting seat 73, and a flexible hose 75 is provided at the top of the annular dust collection hood 74. The flexible hose 75 is used to connect to an external vacuuming device to generate negative pressure suction force in the annular dust collection hood 74. The hose 75 generates suction by connecting to an external vacuum device and uses the annular dust suction hood 74 to suck up debris from the diaphragm surface and the cutting area, rather than just removing the smoke and dust generated during the cutting process. The lifting cylinder 71 is used to adjust the height between the annular dust suction hood 74 and the diaphragm, so that the annular dust suction hood 74 is as close as possible to the diaphragm surface, causing the suction to be concentrated around the cutting area, ensuring that the debris is quickly sucked up as soon as it is generated, thereby preventing the debris from spreading or adhering to the diaphragm surface.

[0039] like Figure 3 and Figure 4 As shown, the lifting and dust collection mechanism 7 further includes a hollow cavity seat 76 and nozzles 70. The hollow cavity seat 76 is located on the top of the mounting plate 4. The hollow cavity seat 76 has a clearance hole 761 for the passage of the hose 75. The hollow cavity seat 76 has an annular chamber 762 inside. A plurality of nozzles 70 are spaced apart along the inner peripheral wall of the annular dust collection cover 74. The top of the nozzles 70 passes through the mounting plate 4 and communicates with the annular chamber 762. The nozzles 70 are used to spray high-pressure airflow outward. The top of the hollow cavity seat 76 has an air inlet 763 communicating with the annular chamber 762. The air inlet 763 is used to provide high-pressure airflow to the annular chamber 762. The high-pressure airflow delivered through the hollow cavity seat 76 is ejected from the nozzle 70, forming a directional and powerful airflow that blows away the debris that adheres to the diaphragm during the cutting process due to static electricity or surface adhesion. This effectively overcomes the problem that it is difficult to remove the attached debris by relying solely on negative pressure suction. At the same time, these debris are driven to the negative pressure area of ​​the annular dust collection hood 74, where they are quickly sucked in, thereby enhancing the cleaning effect of debris and dust.

[0040] like Figure 3 As shown, the air outlet of the nozzle 70 is further inclined downward, and the central axes of the air outlets of the plurality of nozzles 70 converge and intersect on the central axis of the annular dust collection hood 74. With this arrangement, high-pressure airflow can be accurately emitted toward the cutting area, thereby blowing the debris attached to the surface of the diaphragm into the dust collection range of the annular dust collection hood 74.

[0041] like Figure 6 and Figure 7 As shown, the bottom of the membrane adsorption plate 3 is further provided with a waste collection box 30, which is used to collect membrane waste generated during the laser cutting process. During the laser cutting process, some of the debris is immediately sucked away by the lifting and suction mechanism 7, but some debris still falls onto the surface or surrounding area of ​​the membrane adsorption plate 3 due to gravity or static dissipation. By setting the waste collection box 30 at the bottom of the membrane adsorption plate 3, these falling debris can be collected uniformly.

[0042] like Figure 7 As shown, the waste collection box 30 is further provided with a suction pipe 31 on its side wall. The suction pipe 31 is used to generate a suction force. A filter screen 32 is provided at the connection between the end of the suction pipe 31 and the waste collection box 30. The filter screen 32 is used to prevent membrane waste from entering the suction pipe 31. The suction pipe 31, when connected to an external suction device, can generate a continuous negative pressure suction force, thereby keeping the emitting membrane tightly attached to the surface of the membrane adsorption plate 3, avoiding displacement caused by external force or vibration during the cutting process. At the same time, this negative pressure suction force can also suck away the debris generated by the membrane during the cutting process.

[0043] like Figure 5 As shown, the fumigation hood 6 is further provided with filter holes 60 on the wall surface near the laser cutting head 5, so as to filter the inhaled smoke particles, thereby blocking larger particles outside the fumigation hood 6 and preventing them from entering the suction system.

[0044] like Figure 1 As shown, it further includes a protective cover 10, which is disposed on the base 1. The protective cover 10 is used to cover and protect the laser cutting head 5, thereby preventing the laser beam from causing harm to the human body, and at the same time isolating the high temperature area to avoid accidents caused by accidental contact.

[0045] like Figure 1 As shown, the protective cover 10 is further provided with a flip-top door 101. The flip-top door 101 is connected to the protective cover 10 via an electric push rod 102. The flip-top door 101 is used to close or open the protective cover 10.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
