Description

Technical Field

[0001] The invention belongs to the field of laser cutting equipment, in particular to a surface treatment laser cutting equipment for manufacturing plastic parts. Background Art

[0002] Laser cutting equipment is a device that uses laser technology to cut and process materials. The laser cutting machine mainly focuses the laser emitted from the laser into a high-power density laser beam through the optical path system, and then irradiates the laser beam to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. At the same time, the high-pressure gas coaxial with the light beam blows away the melted or vaporized material. As the relative position of the light beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting. Compared with traditional cutting equipment, laser cutting equipment has the following advantages when cutting plastic products: First, laser cutting can achieve micron-level errors, and the edges of the cut products are smooth without the need for subsequent polishing. Secondly, laser processing can be performed after the drawing is formed, and samples can be obtained quickly. Then, laser cutting does not require molds, saving mold costs and replacement time, and reducing production costs. In addition, laser cutting can easily process plastic materials of different thicknesses. Finally, the laser cutting process has little impact on the environment, low noise and safe operation. Therefore, laser cutting equipment is widely used in the processing of plastic products.

[0003] In the prior art, the focusing lens on the laser cutting head is easily contaminated by dust after long-term use, and the contaminants will absorb the energy of the laser beam and produce a thermal lens effect, thereby affecting the cutting accuracy and the quality of the beam. This requires staff to regularly clean the focusing lens to keep the lens surface free of dust and impurities. However, the existing cleaning method is mostly for the staff to remove the lens from the cutting head and then wipe the lens with a cotton swab or a dust-free cloth. This cleaning method not only increases the workload of the staff, but also the efficiency of manual wiping is relatively low.

[0004] To this end, the present invention provides a surface treatment laser cutting device for manufacturing plastic parts. Summary of the invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figure 1-Figure 13As shown, a surface treatment laser cutting device for manufacturing plastic parts described in an embodiment of the present invention comprises a workbench 1, a gantry 2 is slidably connected to the workbench 1, a mounting seat 3 is slidably connected to the gantry 2, a laser cutting head 4 is fixedly installed at the bottom of the mounting seat 3, a mounting frame 6 is fixedly connected to the side wall of the mounting seat 3, a cleaning cylinder 5 is fixedly connected to the end of the mounting frame 6 away from the mounting seat 3, a cleaning unit is arranged in the cleaning cylinder 5, a rotating unit is arranged on the mounting frame 6, two placement plates 16 are arranged in the laser cutting head 4, an ear plate 51 is fixedly connected to the side of the placement plate 16 away from the laser cutting head 4, the two ear plates 51 are fixedly connected by a support rod 52, and the rotating unit is adapted to the ear plate 51 located above; during operation, when the staff needs to clean and maintain the focusing lens after using the laser cutting head 4 for a long time, the two placement plates 1 are driven by the rotating unit 6 slides out from the laser cutting head 4 and rotates 180° before sliding into the cleaning cylinder 5. The focusing lens and the protective lens on the two placement plates 16 can then be cleaned and maintained at the same time through the cleaning unit, ensuring that the focusing lens and the protective lens are clean and tidy. This solves the problem in the prior art that the focusing lens on the laser cutting head 4 is easily contaminated by dust after long-term use. The contaminants will absorb the energy of the laser beam and produce a thermal lens effect, thereby affecting the cutting accuracy and the quality of the beam. This requires the staff to regularly clean the focusing lens to keep the lens surface free of dust and impurities. However, the existing cleaning method is mostly that the staff takes the lens out of the cutting head and then wipes the lens with a cotton swab or a dust-free cloth. This cleaning method not only increases the staff's workload, but also has the problem of low efficiency of manual wiping.

[0036] The rotating unit includes a motor 7, a transmission gear set 8 and a rack plate 15. The motor 7 and the guide rod 10 are fixedly installed on the mounting frame 6. A threaded rod 9 is provided between the motor 7 and the guide rod 10. The threaded rod 9 is rotatably connected to the mounting frame 6. The output end of the motor 7 is transmission-connected to the threaded rod 9 through the transmission gear set 8. A screw sleeve 11 is threadedly connected to the threaded rod 9. The screw sleeve 11 is slidably connected to the guide rod 10. The bottom end of the screw sleeve 11 is rotatably connected to a rotating rod 12. The bottom end of the rotating rod 12 is fixedly connected to the top of the ear plate 51 located above. A gear ring 13 is fixedly connected to the rotating rod 12. A bracket 14 is fixedly connected to the mounting frame 6. The bottom end of the bracket 14 is fixedly connected to the rack plate 15. The gear ring 13 meshes with the rack plate 15 When working, the transmission gear set 8 is driven to rotate by the motor 7, so that the threaded rod 9 rotates accordingly, and then the screw sleeve 11 drives the two placement plates 16 to slide out of the laser cutting head 4 until the gear ring 13 on the rotating rod 12 begins to mesh with the rack plate 15, and the screw sleeve 11 continues to drive the placement plates 16 to slide. At the same time, the placement plates 16 rotate with the rotating rod 12. When the gear ring 13 leaves the rack plate 15, the placement plates 16 stop rotating and rotate exactly 180°. Thereafter, the placement plates 16 slide into the cleaning cylinder 5 driven by the screw sleeve 11. After being cleaned by the cleaning unit in the cleaning cylinder 5, the motor 7 is reversed to drive the placement plates 16 to return to the original path and slide into the laser cutting head 4 to complete the cleaning work.

[0037] The cleaning unit comprises a motor 25, a gear 3 29, a fixed sleeve 1 31 and a sponge block 33. Two feed ports 43 are provided on one side of the cleaning cylinder 5 close to the laser cutting head 4. The motor 25 is fixedly installed on one side of the top of the cleaning cylinder 5. The output end of the motor 25 is fixedly connected with a rotating shaft 26, which is rotatably connected to the cleaning cylinder 5. The bottom end of the rotating shaft 26 extends into the inner cavity of the cleaning cylinder 5 and is fixedly connected with three gears 1 27. One side of the three gears 1 27 is meshedly connected with three gears 28. The gears 28 are rotatably connected to the inner cavity of the cleaning cylinder 5. One side of the three gears 28 is meshedly connected with three gears 3 29. Three groups of fixing rings 30 are fixedly connected in the inner cavity of the cleaning cylinder 5. The three gears 3 29 correspond to the three groups of fixing rings 30 one by one and are rotatably connected. The fixing sleeve 1 31 is fixedly connected to the gear 3 29 in the middle, and the fixing sleeves 2 4 are fixedly connected to the two gears 3 29 located above and below. 2. The upper and lower sides of the fixed sleeve 1 31 and the opposite sides of the two fixed sleeves 2 42 are provided with telescopic components. The fixed sleeve 1 31 and the two fixed sleeves 2 42 are respectively connected to the four sponge blocks 33 through four telescopic components. The four sponge blocks 33 are respectively corresponding to the two feeding ports 43 in groups of two. During operation, when the placement plate 16 slides into the cleaning cylinder 5, the motor 2 25 drives the rotating shaft 26 to rotate forward, so that the gear 1 27 cooperates with the gear 2 28 to drive the gear 3 29 to rotate, thereby making the fixed sleeve 1 31 and the fixed sleeve 2 42 rotate forward accordingly, and with the cooperation of the telescopic components, the sponge blocks 33 on both sides of the fixed sleeve 1 31 and the sponge blocks 33 on the opposite sides of the two fixed sleeves 2 42 rotate accordingly and approach the lenses on the two placement plates 16 to complete the rotary cleaning. When the cleaning is completed, the motor 2 25 is reversed, and the sponge blocks 33 move away from the lenses accordingly, so that the placement plate 16 can slide out of the cleaning cylinder 5.

[0038] The telescopic assembly includes a limit rod 32 and a guide ring 35. The upper and lower sides of the fixed sleeve 31 and the opposite sides of the two fixed sleeves 42 are slidably connected to the limit rod 32. The upper and lower sides of the fixed sleeve 31 and the opposite sides of the two fixed sleeves 42 are provided with a guide ring 35. A connecting rod 34 is fixedly connected between the guide ring 35 and the fixed ring 30. A guide groove 39 is opened on the inner wall of the guide ring 35. The guide groove 39 consists of two annular grooves located at the upper and lower parts and a spiral groove located in the middle, away from An arc stopper 40 is fixedly connected to the connection between the annular groove and the spiral groove on one side of the sponge block 33, and an arc stopper 2 41 is fixedly connected to the connection between the annular groove and the spiral groove near the sponge block 33. A T-shaped groove is provided on the limit rod 32, and a T-shaped block 37 is slidably connected in the T-shaped groove of the limit rod 32. A spring 36 is fixedly connected between the T-shaped block 37 and the inner wall of the T-shaped groove of the limit rod 32. A slider 38 is fixedly connected to the end of the T-shaped block 37 away from the spring 36, and the slider 38 is slidably connected to the guide groove 39. When working, when When the fixed sleeve 1 31 and the fixed sleeve 2 42 drive the limit rod 32 to rotate forward, the slider 38 rotates in the annular groove away from the sponge block 33 to the arc stopper 1 40, slides into the spiral groove along the arc stopper 1 40, and rotates and rises until the slider 38 slides into the annular groove close to the sponge block 33. At this time, the sponge block 33 approaches the lens in the placement plate 16. Thereafter, driven by the forward rotating limit rod 32, the slider 38 continuously rotates around the annular groove close to the sponge block 33 and passes through the arc stopper 1 40. The arc stopper 241 is rotated until the motor 25 is reversed after the cleaning is completed, and the limit rod 32 drives the slider 38 to reverse, so that when the slider 38 rotates in the annular groove close to the sponge block 33 to the arc stopper 241, it slides into the spiral groove along the arc stopper 241 and rotates down until the slider 38 returns to the annular groove away from the sponge block 33 side again, and rotates around the annular groove away from the sponge block 33 side. The rising and falling of the sponge block 33 is realized by the slider 38 cooperating with the guide ring 35.

[0039] One side of the arc stopper 40 and the arc stopper 2 41 are both curved and matched with the spiral groove, and the arc stopper 40 and the arc stopper 2 41 are both provided with inclined surfaces; when working, the curved surfaces provided on the arc stopper 40 and the arc stopper 2 41 facilitate the slider 38 to slide from the annular groove into the spiral groove, and the inclined surfaces provided on the arc stopper 40 and the arc stopper 2 41 make it easier for the slider 38 to slide from the annular groove into the spiral groove, and the T-block 37 is driven by the slider 38 to squeeze the spring 36 each time the slider 38 slides to the inclined surface until the slider 38 leaves the arc stopper 40 and the arc stopper 2 41, and the T-block 37 drives the slider 38 to reset under the elastic force of the spring 36, so that the slider 38 can continue to rotate around the annular groove after entering the annular groove from the spiral groove without changing the rotation direction of the limit rod 32.

[0040] An air blowing hole 44 and an air blowing hole 45 are respectively provided on the upper and lower sides of the feed port 43, and the air blowing hole 44 and the air blowing hole 45 are both in the shape of inclined strips. An air pump 46 is fixedly installed on the top of the cleaning tube 5, and an air blowing pipe 47 is fixedly connected to the air pump 46, and the air blowing pipe 47 is connected to the air blowing hole 44 and the air blowing hole 45; during operation, when the placement plate 16 passes through the feed port 43, air is blown into the air blowing hole 44 and the air blowing hole 45 through the air pump 46 and the air blowing pipe 47, so that the air blowing hole 44 and the air blowing hole 45 can perform pneumatic dust removal on the upper and lower surfaces of the lenses on the placement plate 16 from the upper and lower sides respectively, thereby realizing pretreatment before the sponge block 33 rotates and wipes.

[0041] A dust suction pump 22 is fixedly installed at the bottom of the cleaning cylinder 5, a dust suction chamber is provided below the inner cavity of the cleaning cylinder 5, the dust suction pump 22 is communicated with the dust suction chamber of the cleaning cylinder 5, a dust suction pipe 23 is fixedly connected to one side of the cleaning cylinder 5, a dust collecting cover 24 is fixedly connected to the end of the dust suction pipe 23 away from the cleaning cylinder 5, the dust suction pipe 23 is communicated with the dust suction chamber of the cleaning cylinder 5, a filter plate 48 is fixedly connected to the inner wall of the dust suction chamber of the cleaning cylinder 5, a brush plate 50 is provided on the top of the filter plate 48, a support shaft 49 is fixedly connected to the top of the brush plate 50, and the top end of the support shaft 49 extends into the inner cavity of the cleaning cylinder 5 and is fixedly connected to the fixed sleeve 24 below; when working, by When the laser is cutting plastic products, part of the cut material is directly vaporized, and part of the material will combine with fine particles in the air to form dust and smoke, causing pollution to the working environment of the staff. Therefore, the dust and smoke generated by the laser cutting head 4 during cutting can be absorbed by the dust pump 22 in conjunction with the dust suction pipe 23 and the dust hood 24, and the dust impurities can be filtered through the filter plate 48. The fixed sleeve 42 can drive the support shaft 49 to rotate, so that the brush plate 50 can regularly rotate and clean the filter plate 48 to prevent impurities from clogging the filter plate 48 and affecting the filtering effect.

[0042] An annular protrusion 17 is provided at the bottom of the placement plate 16, and two arc grooves 18 are symmetrically provided on the inner wall of the placement plate 16. An opening is provided on the top of one side of the arc groove 18, and a pressing ring 19 is provided on the top of the placement plate 16. Two positioning plates 20 are symmetrically fixed to the outer wall of the pressing ring 19, and the positioning plate 20 is slidably connected to the arc groove 18; during operation, when the lens is severely worn and needs to be replaced, the screw sleeve 11 is driven by the motor 7 to drive the placement plate 16 to slide out, and the staff then rotates the pressing ring 19 until the positioning plate 20 corresponds to the opening on the arc groove 18, and removes the pressing ring 19 from the placement plate 16, so as to realize the replacement of the lens. After the replacement is completed, the reverse operation is performed, and the lens can be pressed and fixed by the pressing ring 19 in cooperation with the annular protrusion 17.

[0043] The top of the positioning plate 20 is a wavy rubber, and a positioning plate 21 is fixedly connected to the top of the side of the arc groove 18 away from the opening. The bottom of the positioning plate 21 is provided with a wavy rubber, and the positioning plate 20 and the positioning plate 21 are adapted to each other; when working, the wavy rubber provided on the positioning plates 1 20 and 21 increases the friction between the positioning plates 1 20 and 21 after the pressure ring 19 rotates in the arc groove 18, thereby further improving the fixing effect of the pressure ring 19.

[0044] The inner side of the pressure ring 19 and the inner side of the annular protrusion 17 are both provided with chamfers; during operation, by providing chamfers on the inner side of the pressure ring 19 and the inner side of the annular protrusion 17, when the placement plate 16 passes through the feed port 43, the gas blown out from the blowing hole 1 44 and the blowing hole 2 45 can carry away some dust particles on the upper and lower surfaces of the lens directly along the chamfers.

[0045] Working principle: when the staff needs to clean and maintain the focusing lens after using the laser cutting head 4 for a long time, the two placement plates 16 are driven by the rotating unit to slide out of the laser cutting head 4 and rotate 180° and then slide into the cleaning tube 5. The focusing lens and the protective lens on the two placement plates 16 can be cleaned and maintained at the same time through the cleaning unit, ensuring that the focusing lens and the protective lens are clean and tidy. The transmission gear set 8 is driven by the motor 7 to rotate, so that the threaded rod 9 rotates accordingly, and then the screw sleeve 11 drives the two placement plates 16 to slide out of the laser cutting head 4 until the gear ring 13 on the rotating rod 12 starts to mesh with the rack plate 15, and the screw sleeve 11 continues to drive the placement plate 16 to slide, and at the same time, the placement plate 16 rotates with the rotating rod 12 When the gear ring 13 leaves the rack plate 15, the placement plate 16 stops rotating and rotates exactly 180°. Thereafter, the placement plate 16 slides into the cleaning cylinder 5 driven by the screw sleeve 11. After being cleaned by the cleaning unit in the cleaning cylinder 5, the motor 1 7 reverses to drive the placement plate 16 to return to the original path and slide into the laser cutting head 4 to complete the cleaning work. When the placement plate 16 slides into the cleaning cylinder 5, the motor 2 25 drives the rotating shaft 26 to rotate forward, so that the gear 1 27 cooperates with the gear 2 28 to drive the gear 3 29 to rotate, thereby causing the fixed sleeve 1 31 and the fixed sleeve 2 42 to rotate forward accordingly, and with the cooperation of the telescopic assembly, the sponge blocks 33 on both sides of the fixed sleeve 1 31 and the sponge blocks 33 on the opposite sides of the two fixed sleeves 2 42 rotate accordingly and approach the two placement plates 16, completes the rotational cleaning, when the cleaning is completed, the motor 25 reverses, and the sponge block 33 moves away from the lens, so that the placement plate 16 can slide out of the cleaning cylinder 5, and when the fixed sleeve 1 31 and the fixed sleeve 2 42 drive the limit rod 32 to rotate forward, the slider 38 rotates in the annular groove away from the side of the sponge block 33 to the arc stopper 1 40, and then slides into the spiral groove along the arc stopper 1 40 and rotates and rises until the slider 38 slides into the annular groove close to the side of the sponge block 33, at this time, the sponge block 33 approaches the lens in the placement plate 16, and thereafter, driven by the forward rotating limit rod 32, the slider 38 continuously rotates around the annular groove close to the side of the sponge block 33 and passes through the arc stopper 2 41 until the motor 25 reverses after the cleaning is completed. The limit rod 32 then drives the slider 38 to reverse, so that when the slider 38 rotates in the annular groove close to the sponge block 33 to the arc stopper 2 41, it slides into the spiral groove along the arc stopper 2 41 and rotates down until the slider 38 returns to the annular groove away from the sponge block 33 again, and rotates around the annular groove away from the sponge block 33. The slider 38 cooperates with the guide ring 35 to realize the rise and fall of the sponge block 33. The curved surfaces on the arc stopper 1 40 and the arc stopper 2 41 facilitate the slider 38 to slide from the annular groove into the spiral groove. The inclined surfaces on the arc stopper 1 40 and the arc stopper 2 41 make it easier for the slider 38 to slide from the annular groove into the spiral groove. Each time the slider 38 slides to the inclined surface, the T-block 37 is driven by the slider 38 to squeeze the spring 36.Until the slider 38 leaves the arc stopper 1 40 and the arc stopper 2 41, the T-block 37 drives the slider 38 to reset under the elastic force of the spring 36, so that the slider 38 can rotate around the annular groove without changing the rotation direction of the limit rod 32 after entering the annular groove from the spiral groove. When the placement plate 16 passes through the feed port 43, the air pump 46 cooperates with the air blowing pipe 47 to blow air into the air blowing hole 1 44 and the air blowing hole 2 45, so that the air blowing hole 1 44 and the air blowing hole 2 45 can respectively blow the lens on the placement plate 16 from the upper and lower sides. The upper and lower surfaces of the laser cutting head 4 are pneumatically dusted to achieve pretreatment before the sponge block 33 is rotated and wiped. When the laser cuts plastic products, part of the cut material is directly vaporized, and part of the material is combined with fine particles in the air to form dust and smoke, which pollutes the working environment of the staff. Therefore, the dust and smoke generated by the laser cutting head 4 during cutting can be absorbed by the dust pump 22 in conjunction with the dust suction pipe 23 and the dust hood 24, and the dust impurities can be filtered by the filter plate 48, and the fixed sleeve 42 can be used to filter the dust and impurities. The support shaft 49 is driven to rotate so that the brush plate 50 can regularly rotate and clean the filter plate 48 to prevent impurities from clogging the filter plate 48 and affecting the filtering effect. When the lens is seriously worn and needs to be replaced, the screw sleeve 11 is driven by the motor 7 to drive the placement plate 16 to slide out, and the staff can then rotate the pressure ring 19 until the positioning plate 20 corresponds to the opening on the arc groove 18, and then remove the pressure ring 19 from the placement plate 16 to replace the lens. After the replacement is completed, the reverse operation can be performed to realize the replacement of the lens by the pressure ring 19 cooperating with the annular protrusion 17 Now, the lens is pressed and fixed. The wavy rubber on the positioning plate 1 20 and the positioning plate 2 21 increases the friction between the positioning plate 1 20 and the positioning plate 2 21 after the pressing ring 19 rotates in the arc groove 18, further improving the fixing effect of the pressing ring 19. The inner side of the pressing ring 19 and the inner side of the annular protrusion 17 are both provided with chamfers, so that when the placement plate 16 passes through the feed port 43, the gas blown out of the blowing hole 1 44 and the blowing hole 2 45 can carry part of the dust particles on the upper and lower surfaces of the lens and blow them away directly along the chamfers.
