Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent production equipment, and particularly relates to an automatic production device and method for balance weights. Background Art

[0002] During the production process of balance weights, the laser cutting machine can flexibly respond to different product requirements by quickly adjusting cutting parameters and cutting paths, shortening the R & D and production cycles, and rapidly responding to market changes and personalized customer needs.

[0003] The laser cutting mechanism is one of the core components of the laser cutting machine, and it is provided with a lower lens inside. The lower lens can isolate the auxiliary gas and make the auxiliary gas spray out from the nozzle. During cutting, when the auxiliary gas sprays out, it can not only blow the melted or vaporized material away from the cutting area to form a cut, but also prevent impurities such as splashes, dust, and smoke generated during the processing from splashing onto the lower lens.

[0004] However, after each balance weight is cut, the laser cutting mechanism will temporarily stop running for position adjustment. During this process, dirt such as fume and dust generated during the previous laser cutting process will enter the nozzle and then deposit on the surface of the lower lens, resulting in contamination of the lower lens. In addition, the air quality in the cutting workshop is poor, and the auxiliary gas transported by the gas compressor to the nozzle contains dust, which will also contaminate the lower lens inside the laser cutting mechanism. After the lower lens is contaminated, it will affect the refractive index of the lower lens, resulting in a decrease in cutting accuracy, a large deviation between the cutting size and the designed size, and the balance weights cannot meet the quality standards, leading to batch scrapping. Moreover, after the lower lens is contaminated, the light transmittance decreases, the temperature of the lower lens will increase, resulting in the lower lens being burned out, which not only increases the replacement frequency of the lower lens, affects the production efficiency, but also increases the production cost.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an automatic production device and method for balance weights.

[0006] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0039] To enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0040] As Figures 1 to 8 shown, an automatic production device for balance blocks in an embodiment of the present invention includes a machine tool 1, a gas compressor 4, and a control mechanism. Among them, a moving mechanism 2 is installed on the machine tool 1, and a laser cutting mechanism is installed on the moving mechanism 2. The laser cutting mechanism includes a first protective box 3 and a protective block 13. A laser module 6 is fixedly installed in the first protective box 3. The laser module 6 penetrates the lower panel of the first protective box 3 and is flush with the lower panel of the first protective box 3. The protective block 13 is fixedly installed on the laser module 6. A light-transmitting groove 14 matching the laser module 6 is formed on the protective block 13. A nozzle 27 matching the light-transmitting groove 14 is detachably installed on the protective block 13. A lower lens 16 is installed in the protective block 13.

[0041] Specifically, when the automatic production device for balance blocks works, the laser module 6 emits a high-energy laser beam. The high-energy laser beam penetrates the light-transmitting groove 14 and then exits from the nozzle 27 to cut the steel plate 46. At the same time, the gas compressor 4 generates auxiliary gas and transports it into the nozzle 27, and then sprays out from the nozzle 27 to prevent impurities such as flying objects, dust, and smoke generated during cutting from entering the nozzle 27, and at the same time blows the molten steel plate 46 away from the cutting area to form a cut.

[0042] It should be noted that there is a lot of dust in the cutting workshop, and there will be dust in the auxiliary gas generated by the steel plate 46. These dusts will adhere to the lower lens 16, resulting in contamination of the lower lens 16.

[0043] To solve the above problems, a first liquid storage tank 9 is installed on the side wall of the first protective box 3. The first liquid storage tank 9 is filled with a filtering liquid 901. A first air pipe 11 and a second air pipe 12 are installed on the first liquid storage tank 9. One end of the first air pipe 11 away from the first liquid storage tank 9 is installed on the gas compressor 4, and one end of the second air pipe 12 away from the first liquid storage tank 9 is installed on the protective block 13.

[0044] Specifically, there is a gas storage space between the liquid level of the filtrate 901 and the upper cover plate of the first liquid storage tank 9. The second air pipe 12 is installed on the upper end surface of the first liquid storage tank 9 and is communicated with the gas storage space. The auxiliary gas produced when the gas compressor 4 operates enters the filtrate 901 through the first air pipe 11. After the auxiliary gas enters the filtrate 901, bubbles are formed and emerge from the filtrate 901 into the gas storage space, and then enter the protection block 13 through the second air pipe 12 and finally spray out from the nozzle 27. During the process of the bubbles emerging from the filtrate 901, the dust in the auxiliary gas can be adsorbed by the filtrate 901.

[0045] Specifically, since the air pressure delivered by the gas compressor 4 is usually greater than 0.3 Mpa, the pressurized auxiliary gas will form multiple tiny bubbles in the filtrate 901 after entering the filtrate 901. The tiny dust in these small bubbles randomly diffuses to the filtrate 901 due to Brownian motion and is adsorbed by the filtrate 901. This process is remarkable for small particle dust, especially sub-micron dust, ensuring the cleanliness of the auxiliary gas filtered by the filtrate 901. The auxiliary gas filtered by the filtrate 901 enters the protection block 13 through the second air pipe 12 and will not pollute the lower lens 16 after contacting the lower lens 16.

[0046] Furthermore, the automatic balancing block production device further includes a cooler 5. A first cooling pipe 7 is installed on the cooler 5. One end of the first cooling pipe 7 away from the cooler 5 is installed on the laser module 6. A second cooling pipe 8 matching the first cooling pipe 7 is installed on the laser module 6. One end of the second cooling pipe 8 away from the laser module 6 is installed on the first liquid storage tank 9. A third cooling pipe 10 matching the second cooling pipe 8 is installed on the first liquid storage tank 9. One end of the third cooling pipe 10 away from the first liquid storage tank 9 is installed on the cooler 5. A filter element is provided in the cooler 5 for filtering the filtrate 901.

[0047] Specifically, the same filtrate 901 is contained in the cooler 5. When the automatic balancing block production device cuts the steel plate 46, the cooler 5 will also be started. The filtrate 901 in the cooler 5 enters the laser module 6 through the first cooling pipe 7, and then flows into the first liquid storage tank 9 through the second cooling pipe 8. During the flowing process, the temperature of the laser module 6 is reduced to prevent the laser module 6 from overheating and ensure the normal operation of the laser module 6. The filtrate 901 entering the first liquid storage tank 9 flows back to the cooler 5 through the third cooling pipe 10 and enters the next cycle after being filtered by the filter element in the cooler 5.

[0048] Specifically, during the above cycle process, the filtrate 901 not only cools the laser module 6 but also ensures the cleanliness of the filtrate 901 in the first liquid storage tank 9, thereby ensuring the filtering effect of the filtrate 901 in the first liquid storage tank 9 on the auxiliary gas.

[0049] In addition, when the filter liquid 901 cools down the laser module 6, it will absorb the heat of the laser module 6, so that the temperature of the filter liquid 901 entering the first liquid storage tank 9 will also increase. Similarly, after the auxiliary gas is filtered by the filter liquid 901 with an increased temperature, the temperature of the auxiliary gas will also rise. During production operations in winter, it can prevent the auxiliary gas with a lower temperature from blowing on the cutting area of the steel plate 46, resulting in a smaller heat affected zone of the cutting surface and cold brittleness of the cut seam, thereby improving the cutting quality.

[0050] After each balance block is cut, the laser cutting mechanism will temporarily stop running and adjust its position. During the process of adjusting the position, dirt such as oil fume and dust generated during the previous cutting will enter the light transmission groove 14 from the nozzle 27, and then deposit on the lower surface of the lower lens 16, resulting in contamination of the lower lens 16.

[0051] Furthermore, an opening and closing component for protecting the lower lens 16 is provided on the protective block 13. The opening and closing component includes a second protective box 18. A spring 19 is welded to the inner wall of the second protective box 18. One end of the spring 19 away from the second protective box 18 is welded with a mounting plate 20. A blocking plate 21 and a sliding column 22 are integrally formed on the mounting plate 20, and there is a first opening 23 between the blocking plate 21 and the sliding column 22. A second slot 24 and a third slot 25 are formed on the protective block 13. Both the second slot 24 and the third slot 25 are located below the lower lens 16, and a ventilation slot 26 for communicating the second slot 24 and the third slot 25 is formed on the protective block 13. A connecting nozzle 1301 matching the insertion plate 15 is installed on the protective block 13. One end of the second air pipe 12 away from the first liquid storage tank 9 is installed on the connecting nozzle 1301, and a one-way valve is installed on the connecting nozzle 1301.

[0052] Specifically, the blocking plate 21 is slidably connected in the second slot 24, and the sliding column 22 is slidably connected in the third slot 25. When the automatic production device for balance blocks works, the auxiliary gas in the second air pipe 12 flows into the third slot 25. As the air pressure in the third slot 25 increases, it will push the sliding column 22, causing the sliding column 22 to slide in the direction of the spring 19 and compress the spring 19. While the sliding column 22 slides, it will also drive the blocking plate 21 to slide in the direction of the spring 19 through the mounting plate 20. As the blocking plate 21 and the sliding column 22 gradually slide, the blocking plate 21 and the sliding column 22 no longer block the ventilation slot 26, and the auxiliary gas in the third slot 25 flows into the ventilation slot 26, then into the light transmission groove 14, and finally sprays out from the nozzle 27. At this time, the laser beam emitted by the laser module 6 passes through the light transmission groove 14 and can also be emitted from the nozzle 27 for cutting operations.

[0053] Preferably, when cutting the steel plate 46, the gas compressor 4 first supplies auxiliary gas into the first cooling pipe 7. Two seconds later, the laser module 6 is started. During this time, the auxiliary gas pushes open the plug plate 21 and the sliding column 22, and finally sprays out from the nozzle 27. At this time, the laser module 6 just emits a laser beam. The laser beam passes through the light-transmitting groove 14 and then also sprays out from the nozzle 27 to cut the steel plate 46.

[0054] When the laser cutting mechanism stops running, the second air pipe 12 no longer transports auxiliary gas into the third slot 25. As the auxiliary gas gradually sprays out from the nozzle 27, the air pressure in the third slot 25 and the second slot 24 decreases, and the spring 19 elastically elongates, pushing the plug plate 21 and the sliding column 22. At this time, the plug plate 21 can block the light-transmitting groove 14. After the light-transmitting groove 14 is blocked, there is a blockage of the plug plate 21 between the lower lens 16 and the nozzle 27, and dirt such as oil fume and dust generated during the previous cutting will not contaminate the lower lens 16, playing a protective role for the lower lens 16.

[0055] It should be noted that when the sliding column 22 gradually slides towards the connecting nozzle 1301 in the third slot 25, the space in the third slot 25 is compressed, resulting in an increase in the air pressure of the remaining auxiliary gas in the third slot 25, which may affect the normal sliding of the sliding column 22. At this time, the one-way valve on the connecting nozzle 1301 can discharge the gas with excessive pressure in the third slot 25, ensuring that the elastic elongation force of the spring 19 can push the sliding column 22 to slide in the third slot 25, thereby ensuring the blocking ability of the plug plate 21 to the light-transmitting groove 14.

[0056] Furthermore, a distance sensor 181 is installed on the inner wall of the second protective box 18. The distance sensor 181 is used to detect the distance between the mounting plate 20 and the distance sensor 181. During cutting, if the distance between the mounting plate 20 and the distance sensor 181 is too large, it indicates that the pressure of the auxiliary gas is insufficient, and the control mechanism will increase the power of the gas compressor 4 to ensure the cutting quality; if the distance between the mounting plate 20 and the 151 is too small, the control mechanism will reduce the power of the gas compressor 4 to save energy. Compared with the traditional method of installing a pressure detection device on the gas compressor 4, the above-mentioned detection method closer to the terminal can be more accurate.

[0057] Furthermore, a first slot 17 is formed on the protective block 13, and a plug board 15 is inserted into the first slot 17. The lower lens 16 is detachably installed on the plug board 15. Specifically, bolts are provided on the plug board 15, and threaded holes are formed on the protective block 13. The plug board 15 is threadedly connected to the protective block 13. When the lower lens 16 needs to be replaced after reaching the service life, turn the bolt so that the bolt moves away from the threaded hole on the protective block 13, and the plug board 15 can be pulled out from the first slot 17, facilitating the replacement and installation of the lower lens 16.

[0058] It should be noted that laser cutting belongs to thermal processing. The high-energy laser beam instantaneously heats a local area of the steel plate 46, causing uneven thermal expansion and cooling contraction of the steel plate 46, resulting in internal stress. As the cutting operation progresses, the stress of the steel plate 46 gradually increases, and the steel plate 46 will warp and deform. During the cutting process, the nozzle 27 will directly impact the warped part, causing the nozzle 27 to deform or even rupture, increasing production costs and reducing production efficiency. In addition, when the nozzle 27 is replaced for re-cutting, a notch will appear at the cutting start point of the cutting part, and additional welding is required in subsequent production, increasing additional processes.

[0059] To solve the above problems, as Figures 7 to 12 shown, a pair of connecting frames 28 are welded on the moving mechanism 2. A slide rail 281 is welded on the pair of connecting frames 28. A sliding block 282 is slidably connected to the slide rail 281. A third protective box 29 is installed on the sliding block 282. An anti-warping mechanism is installed in the third protective box 29. The sliding block 282 moves synchronously with the movement of the laser cutting mechanism.

[0060] The anti-warping mechanism includes a second liquid storage tank 30. The second liquid storage tank 30 is filled with pure water. A ventilation pipe 31 is welded on the second liquid storage tank 30. The ventilation pipe 31 penetrates through the second liquid storage tank 30 and is hermetically connected to the second liquid storage tank 30. A pressure tank 32 matching the second liquid storage tank 30 is installed in the third protective box 29. A third air pipe 321 is installed on the pressure tank 32. One end of the third air pipe 321 far from the second liquid storage tank 30 is installed on the second liquid storage tank 30. A high-temperature magnetic pump 33 is provided on the pressure tank 32. A fifth air pipe 331 is installed on the high-temperature magnetic pump 33. A tee pipe 34 is installed on the fifth air pipe 331. A pair of jet nozzles 37 are installed on the tee pipe 34. An electromagnetic valve 36 matching the jet nozzles 37 is installed on the tee pipe 34.

[0061] Specifically, the center of the ventilation pipe 31 is concentric with the nozzle of the nozzle 27. When cutting the steel plate 46, the laser beam melts the steel plate 46, and the auxiliary gas blows away the molten steel plate 46 to form a cut. When the steel plate 46 is cut through, the auxiliary gas is heated to a very high temperature by the molten steel plate 46 and is sprayed into the ventilation pipe 31 to bake the inner wall of the ventilation pipe 31. The inner wall of the ventilation pipe 31 will heat the pure water in the second liquid storage tank 30.

[0062] As the cutting operation progresses, the pure water in the second liquid storage tank 30 boils to generate steam. These steam enters the pressurizing tank 32 through the third air pipe 321, and after being pressurized by the pressurizing tank 32, the temperature rises to 450 °C. Then it is transported to the three-way pipe 34 by the high-temperature magnetic pump 33. After the solenoid valve 36 on the three-way pipe 34 is opened, the high-temperature steam is sprayed on the lower surface of the steel plate 46 by the jet head 37. At this time, after the steel plate 46 is heated by the high-temperature steam sprayed by the jet head 37, the heated area of the steel plate 46 increases, the temperature difference between the cut seam of the steel plate 46 and the rest of the area decreases, and a part of the internal stress is eliminated, so as to prevent the steel plate 46 from warping and deforming during cutting, and further prevent the nozzle 27 and the steel plate 46 from colliding during the cutting operation, ensuring the normal progress of the cutting work.

[0063] In addition, when cutting a relatively thick steel plate 46 in winter, the relatively thick steel plate 46 is heated by spraying high-temperature steam through the jet head 37, which is beneficial to the laser beam penetrating the relatively thick steel plate 46. During cutting, the power of the laser cutting mechanism can be adjusted downwards, which not only reduces energy consumption, but also extends the service life of the laser module 6 and the nozzle 27, reducing production costs.

[0064] Furthermore, a steam-water separator 35 is installed on the fifth air pipe 331, a first water delivery pipe 351 is installed on the steam-water separator 35, one end of the first water delivery pipe 351 away from the steam-water separator 35 is installed on the second liquid storage tank 30, a water replenishing tank 38 is installed in the third protective box 29, a water pump 39 is installed on the water replenishing tank 38, and a second water delivery pipe 391 is installed on the water pump 39. Both ends of the second water delivery pipe 391 are installed on the second liquid storage tank 30 and the connecting frame 28 respectively.

[0065] Specifically, the moisture inside the high-temperature steam is removed after passing through the steam-water separator 35, and then returns to the second liquid storage tank 30 through the first water delivery pipe 351. Moreover, the water pump 39 can also replenish the pure water in the second liquid storage tank 30 to ensure that the second liquid storage tank 30 can continuously generate steam during cutting.

[0066] Furthermore, a pair of supporting grooves 101 are provided on the machine tool 1, a supporting plate 41 is slidably connected in the supporting grooves 101, and the supporting plate 41 is slid according to the width of the steel plate 46 to be cut, so that the distance between the pair of supporting plates 41 matches the steel plate 46 to be cut. Vertical plates are provided on both of the pair of supporting plates 41, bolts are provided on the vertical plates, and a plurality of threaded holes are provided on the machine tool 1. By screwing the bolts on the vertical plates, the supporting plate 41 can be fixed in the supporting grooves 101.

[0067] It should be noted that since the anti-warping mechanism is below the steel plate 46 to be cut, the balance blocks obtained by cutting the steel plate 46 will hit the anti-warping mechanism. Further, a protective plate 40 is welded on the upper panel of the third protective box 29, and the included angle between the protective plate 40 and the upper panel of the third protective box 29 is 35-45°. The balance blocks obtained after cutting the steel plate 46 fall on the protective plate 40 and then fall into the machine tool 1 after being guided by the protective plate 40, which can prevent the anti-warping mechanism from being hit.

[0068] In addition, when the balance blocks fall from the protective plate 40 into the machine tool 1, they will flip after being guided by the protective plate 40, making the lower panel of the balance blocks face upward. As is well known, the burrs and cutting slag generated during cutting will adhere to the lower part of the cut of the balance blocks. After the balance blocks are flipped, the subsequent grinding process does not need to flip the balance blocks again, which is convenient for the subsequent grinding work.

[0069] Further, as Figure 8 , Figure 9 and Figure 13 , when cutting the steel plate 46, first cut the A area according to the cutting path, and then cut the B, C, D and other areas in turn according to the cutting path of the A area. In this way, the balance blocks obtained after cutting will fall at one end far from the laser cutting mechanism after being guided by the protective plate 40 when they fall from the steel plate 46. When cutting the subsequent areas, the slag generated on the steel plate 46 will not fall on the cut balance blocks, ensuring the cleanliness of the balance blocks and reducing the subsequent grinding workload.

[0070] Furthermore, a second opening 42 is provided on the machine tool 1, a receiving cart 43 is provided in the second opening 42, an electric wheel 44 is installed on the receiving cart 43, and a stop block 45 is fixedly connected to the machine tool 1. Specifically, after the steel plate 46 is cut, all the cut balance blocks fall into the receiving cart 43. By issuing an instruction through the control mechanism, the electric wheel 44 rotates, and the receiving cart 43 moves out of the second opening 42, so that the balance blocks in the receiving cart 43 can be taken out. Then, by issuing an instruction through the control mechanism, the electric wheel 44 rotates and the receiving cart 43 slides into the second opening 42 again until it fits against the stop block 45, and the electric wheel 44 stops rotating.

[0071] Of course, a balance block automatic production device can be configured with multiple receiving carts 43. The receiving cart 43 loaded with balance blocks travels to the grinding work, and the empty receiving cart 43 enters the second opening 42 to wait for the cutting work of the next steel plate 46.

[0072] During use, as Figures 1 to 7As shown, the gas compressor 4 starts to supply auxiliary gas. The auxiliary gas flows into the first liquid storage tank 9 under the guidance of the first air pipe 11, and then is filtered by the filter liquid 901 in the first liquid storage tank 9 to obtain clean auxiliary gas. The clean auxiliary gas flows into the third slot 25 through the second air pipe 12. As the air pressure in the third slot 25 increases, the sliding column 22 slides outward in the third slot 25, and the plug plate 21 also slides outward in the second slot 24, and then the light-transmitting slot 14 will be opened, and the spring 19 is in a compressed state. At this time, the auxiliary gas in the third slot 25 enters the light-transmitting slot 14 from the ventilation slot 26 and then sprays out from the nozzle 27. Then the laser module 6 emits a laser beam that passes through the lower lens 16 and penetrates the light-transmitting slot 14 and then shoots out from the nozzle 27 to perform cutting work.

[0073] After cutting a balance block, the laser cutting mechanism stops working. At this time, the gas compressor 4 also stops supplying auxiliary gas. After the auxiliary gas in the third slot 25 sprays out from the nozzle 27, the air pressure decreases, and the spring 19 elastically elongates, pushing the mounting plate 20 to make the plug plate 21 and the sliding column 22 slide into the second slot 24 and the third slot 25 respectively. The auxiliary gas in the third slot 25 is discharged from the one-way valve on the connecting nozzle 1301. When the mounting plate 20 fits against the side wall of the protection block 13, the light-transmitting slot 14 will be blocked by the plug plate 21, and the ventilation slot 26 is also blocked by the sliding column 22, preventing dirt such as oil fume and dust generated during the previous cutting from entering the light-transmitting slot 14 from the nozzle 27 when the laser cutting mechanism moves, resulting in contamination of the lower lens 16.

[0074] In addition, when replacing the steel plate 46 on the machine tool 1 or when the balance block automatic production device is idle, it can also prevent the lower lens 16 from being contaminated by dust in the air.

[0075] When the gas compressor 4 supplies auxiliary gas, the cooler 5 will also start. The cooler 5 supplies the filter liquid 901. The filter liquid 901 passes through the first cooling pipe 7 and enters the laser module 6 to cool the laser module 6. The filter liquid 901 that enters the laser module 6 absorbs the heat of the laser module 6 and then flows into the first liquid storage tank 9 through the second cooling pipe 8, and then returns to the cooler 5 through the third cooling pipe 10 to realize the circulation of the filter liquid 901. And the cooler 5 filters the filter liquid 901 to ensure the cleanliness of the filter liquid 901, thereby ensuring the filtering effect of the filter liquid 901 in the first liquid storage tank 9.

[0076] In addition, the filter liquid 901 that enters the first liquid storage tank 9 absorbs the heat of the laser module 6 and becomes hot itself, and it will also heat the auxiliary gas that enters the first liquid storage tank 9. In winter in the northeastern region where the temperature is relatively low, after the auxiliary gas is heated, it can increase the heat affected zone of the cutting surface and prevent cold brittleness from occurring in the cut seam, thereby improving the cutting quality.
