Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of painting devices, in particular to a painting device for the production of gas generators. Background Art
[0002] Gas generators of different specifications are provided inside the airbag. When the vehicle collides, the gas generator inflates and deploys the airbag to protect the safety of passengers. In the prior art, in order to extend the service life of the gas generator, paint is often sprayed on the surface of the gas generator to protect it.
[0003] Most of the nozzles used in traditional painting devices for the production of gas generators are fixed. Since the lengths of different gas generators are not the same, in order to ensure that the paint sprayed by the nozzle completely covers the surface of the gas generator, it is often necessary to increase the paint flow rate to increase the coverage area of the nozzle. Although this method can perform better painting treatment on the surface of the gas generator, in actual use, the nozzle with a large flow rate greatly increases the production cost of the gas generator painting treatment, and the practical performance of the device is poor;
[0004] Moreover, during the actual use of the existing painting device for the production of gas generators, we found that due to different car models, the specifications and dimensions of the gas generators are slightly different. In the prior art, in order to ensure the painting treatment of gas generators with different specifications and dimensions, the gas generator is often only placed in the placement cylinder on the guide sleeve for transportation. Since the placement cylinder needs to transport gas generators with various specifications and dimensions, the inner diameter of the placement cylinder should be slightly larger than the diameter of the gas generator. This results in the gas generator being prone to tilting and rotating during the process of rotary painting. When the centrifugal force generated by the rotation of the placement cylinder is relatively large, the gas generator will be thrown out of the placement cylinder under the action of the centrifugal force, causing unnecessary production failures, and the actual practical effect of the device is not good.
[0005] On the other hand, during the painting process of the existing painting device for the production of gas generators, a small amount of paint will pass through the gas generator and be sprayed onto the baffle. And over time, the paint layer coated on the wall surface will gradually thicken. If it cannot be cleaned in time, the dried paint surface is extremely prone to peeling due to excessive accumulation. If the painting device still performs painting treatment on the gas generator at this time, the paint surface peeled off from the baffle is extremely prone to floating onto the painted surface of the gas generator and adhering to the surface of the gas generator through the adhesion of the paint, thereby affecting the forming quality of the gas generator after painting, and the practical performance of the device is poor;
[0006] Therefore, we designed a painting device for the production of gas generators to provide another technical solution for the above technical problems. Summary of the Utility Model

[0031] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0032] Embodiment 1
[0033] Referring to Figure 1-8 , a painting device for the production of a gas generator 4, includes a first workbench 1, a second workbench 2, a baffle 3 and a gas generator 4. The second workbench 2 is arranged on one side of the first workbench 1. The baffle 3 is fixedly arranged in the middle of the top of the first workbench 1. A painting assembly for painting the gas generator 4 is arranged on the first workbench 1, and a conveying mechanism for transporting the gas generator 4 is arranged on the top of the first workbench 1.
[0034] Referring to Figure 2-4, the painting component includes a mounting block 5 slidably arranged on the surface of the second workbench 2.

The mounting block 5 is slidably clamped on the electric slide rail 7. A moving block 8 is slidably clamped inside the mounting block 5. One side of the moving block 8 close to the inside is threadedly connected with a first adjusting screw rod 9. One end of the first adjusting screw rod 9 is rotatably connected to the inner wall of the mounting block 5. The other end of the first adjusting screw rod 9 penetrates through the mounting block 5 and is connected with a first driving motor 10. One side of the moving block 8 close to the outside is fixedly connected with a painting rod 11. A plurality of spray heads 12 are fixedly arranged on the painting rod 11. Specifically, in the present utility model, through the design of the electric slide rail 7, the axial position adjustment of the painting component is realized, so that the painting component can be adjusted axially according to different parameter settings, improving the applicability of the device. Through the design of the first adjusting screw rod 9, the moving block 8 and the first driving motor 10, the staff can adjust the radial position of the painting component according to the different lengths of the gas generator 4, so that the painting component can always be located in the middle of the gas generator 4. Thus, while ensuring that the paint sprayed by the spray heads 12 can completely cover the surface of the gas generator 4, the output flow of the spray heads 12 is effectively reduced, so as to reduce the production cost of the painting treatment of the gas generator 4 and improve the practical performance of the device.
[0035] It should be noted that in the present utility model, a delivery pump and a paint storage tank are externally connected to the painting rod 11. Through this design, the paint supply treatment for the plurality of spray heads 12 on the painting rod 11 is realized, ensuring the normal operation of the painting component.
[0036] When it is necessary to adjust the axial position of the painting component, the staff only needs to start the electric slide rail 7 to realize the adjustment of the axial position of the painting component.
[0037] When it is necessary to adjust the radial position of the painting component, the staff drives the first adjusting screw rod 9 to rotate by starting the first driving motor 10, so that the moving block 8 threadedly connected to the first adjusting screw rod 9 moves radially inside the mounting block 5, and the adjustment of the radial position of the painting component can be realized.
[0038] Refer to Figure 2-3 And Figure 5-6, the conveying mechanism includes an annular conveying component and a clamping component. The annular conveying component includes a first sprocket 13 symmetrically arranged on the surface of the first workbench 1. A first chain 14 is externally engaged with the first sprocket 13. A first rotating shaft 15 is fixedly provided in the middle of the first sprocket 13. The first sprocket 13 is rotatably arranged on the first workbench 1 through the first rotating shaft 15. A second driving motor 16 is fixedly provided at the bottom of the first workbench 1. One end of one of the first rotating shafts 15 penetrates through the first workbench 1 and is fixedly connected to the output end of the second driving motor 16. A sliding guide rail 17 is arranged around the first chain 14. A plurality of sliding seats 18 are slidably connected to the sliding guide rail 17. One side of the sliding seat 18 close to the first chain 14 is hinged to the first chain 14 through a pin shaft. A guide sleeve 19 is fixedly provided at the top of the plurality of sliding seats 18. A plurality of placement cylinders 20 for conveniently placing the gas generator 4 are arranged at the top of the guide sleeve 19. Specifically, in the present utility model, through the design of the first sprocket 13, the first chain 14, the first rotating shaft 15 and the second driving motor 16, the conveying rotation of the first chain 14 on the first workbench 1 is realized, so that a plurality of sliding seats 18 on the first chain 14 can slide on the guide rail, and the sliding sleeve fixedly connected to the top of the sliding seat 18 is driven to circularly convey the gas generator 4 in the placement cylinder 20, ensuring the normal operation of the subsequent painting treatment.
[0039] Refer to Figure 5-6 , an annular installation groove 21 and an installation hole 22 are sequentially opened in the guide sleeve 19 from top to bottom. A second rotating shaft 23 is fixedly provided at the bottom end of the placement cylinder 20. One end of the second rotating shaft 23 away from the placement cylinder 20 penetrates through the guide sleeve 19 and is rotatably connected to the bottom wall of the annular installation groove 21. A second sprocket 24 is fixedly connected to a section of the second rotating shaft 23 located in the annular installation groove 21. A second chain 25 for transmission is externally engaged with the second sprocket 24. A third driving motor 26 is fixedly arranged in the installation hole 22. The output end of the third driving motor 26 penetrates through the top wall of the installation hole 22 and is fixedly connected to the bottom end of one of the second rotating shafts 23. Specifically, in the present utility model, through the design of the second rotating shaft 23, the second sprocket 24, the second chain 25 and the third driving motor 26, the rotational movement of the placement cylinder 20 at the top of the guide sleeve 19 is realized, so as to facilitate the cooperation with the painting component to comprehensively paint the gas generator 4 placed in the placement cylinder 20, effectively ensuring the painting quality of the gas generator 4.
[0040] Refer to Figure 6, the clamping assembly is arranged inside the placement cylinder 20. The clamping assembly includes a plurality of clamping strips 27 annularly distributed inside the placement cylinder 20. A plurality of guiding and limiting grooves 28 matching the clamping strips 27 are opened at the bottom end of the placement cylinder 20. The top end of the clamping strip 27 is fixedly connected with a guiding inclined plate 29. A plurality of compression springs 30 are fixedly connected to the outer side of the clamping strip 27. The end of the compression spring 30 far away from the clamping strip 27 is fixedly connected with the inner wall of the placement cylinder 20. Specifically, in the present utility model, through the design of the clamping assembly, the position of the gas generator 4 placed in the placement cylinder 20 is fixedly clamped, so as to avoid the gas generator 4 being thrown out of the placement cylinder 20 due to the large centrifugal force during the rotary spraying, effectively ensuring the stability of the rotary spraying process of the gas generator 4 and improving the actual use effect of the device. At the same time, through the design of the clamping strip 27, the compression spring 30 and the guiding inclined plate 29, the gas generator 4 with different size specifications can also be fixedly clamped, improving the applicability of the device. Through the design of the guiding and limiting groove 28, the moving positions of the clamping strip 27 and the guiding inclined plate 29 are restricted, so that the clamping strip 27 and the guiding inclined plate 29 can always centeringly clamp the gas generator 4 along the guiding and limiting groove 28 under the action of the compression spring 30, effectively improving the stability during the clamping process;
[0041] When the staff places the gas generator 4 into the placement cylinder 20, the bottom end of the gas generator 4 continuously squeezes the guiding inclined plate 29. The squeezed guiding inclined plate 29 drives the clamping strip 27 to squeeze the compression spring 30, and gradually enters the placement cylinder 20 under the guiding action of the guiding inclined plate 29 and abuts against the side wall of the clamping strip 27. When the bottom end of the gas generator 4 abuts against the bottom wall of the placement cylinder 20, the clamping strip 27 always abuts against the outer wall of the gas generator 4 under the elastic force of the compression spring 30, and the restriction of the position of the gas generator 4 in the placement cylinder 20 can be completed;
[0042] When the device is spraying paint on the gas generator 4 in the placement cylinder 20, the staff first adjusts the axial and radial parameters of the paint spraying component according to the specifications of the gas generator 4 through the cooperation between the electric slide rail 7, the drive motor 10, the adjusting screw 9 and the moving block 8, so that the paint spraying component is kept in the best paint spraying position, and then starts the drive motor 216 to make the sprocket 13 drive the chain 14 to move, thereby driving the slide 18 fixedly connected to the chain 14 to slide on the guide rail, so that the guide sleeve 19 at the top of the slide 18 performs annular movement, thereby realizing the annular conveyance of the placement cylinder 20 at the top of the guide sleeve 19, and when the placement cylinder 20 at the front end of the guide sleeve 19 is about to be separated from the spray of the paint spraying component When the paint range is reached, the drive motor 2 16 stops and the drive motor 3 26 starts, thereby driving the placement tube 20 to rotate through the sprocket 24, chain 25 and shaft 23 inside the guide sleeve 19, so that the paint spraying component can comprehensively paint the gas generator 4 placed in the placement tube 20. When the gas generator 4 located within the coverage range of the paint spraying component is painted, the drive motor 3 26 stops and the drive motor 2 16 starts, driving the painted gas generator 4 to be transported forward, and then the staff dries the paint surface on the surface of the gas generator 4 after the paint treatment or waits for the paint surface to dry naturally, then removes the gas generator 4, and places the gas generators 4 to be painted into the placement tube 20 one by one.
[0043] Embodiment 2
[0044] The present embodiment is further optimized on the basis of the first embodiment. In the process of painting, a small amount of paint will be sprayed onto the baffle 3 through the gas generator 4 in the existing paint spraying device for producing the gas generator 4, and as time goes by, the paint surface coated on the wall will gradually become thicker. If it is not cleaned in time, the dried paint surface is very likely to fall off due to excessive accumulation. If the paint spraying device is still painting the gas generator 4 at this time, the paint surface falling off the baffle 3 is very likely to fall onto the painted surface of the gas generator 4, and adhere to the surface of the gas generator 4 through the adhesion of the paint, thereby affecting the molding quality of the gas generator 4 after painting, and the practical performance of the device is poor.
[0045] Reference Figure 7-8The baffle plate 3 is provided with a cleaning component for cleaning the paint on the surface of the baffle plate 3, and the cleaning component includes an L-shaped slider 31 slidably connected on both sides of the baffle plate 3, and the baffle plate 3 is provided with a second slide groove 32 matching the L-shaped slider 31, and one end of the L-shaped slider 31 located in the second slide groove 32 is threadedly connected with an adjusting screw 2 33, and one end of the adjusting screw 2 33 is rotatably connected to the bottom wall of the second slide groove 32, and the other end of the adjusting screw 2 33 passes through the top wall of the second slide groove 32 and is connected to a synchronous pulley 34, and the outer sleeve of the synchronous pulley 34 is provided with a synchronous belt 35 for transmission, and an L-shaped mounting plate 36 is fixedly provided on the top of the baffle plate 3, and a driving motor 4 37 is fixedly provided on the L-shaped mounting plate 36, and the output end of the driving motor 4 37 is fixedly connected to one end of one of the adjusting screws 2 33;
[0046] A coating roller 38 for cleaning the paint on the surface of the baffle 3 is fixedly connected to one side opposite to the L-shaped slider 31. A groove 39 is provided at the bottom end of the baffle 3 to facilitate the extension of the coating roller 38. A accommodating cavity 40 is provided inside the coating roller 38. A bearing plate 41 is provided at the top of the coating roller 38. Both ends of the bearing plate 41 are fixedly connected to the L-shaped slider 31. An electric cylinder 42 is fixedly provided at the top of the bearing plate 41. A scraper 43 for cleaning the paint surface is fixedly connected to the output end of the electric cylinder 42. A liquid storage cylinder 44 is fixedly provided on the side opposite to the scraper 43, and a delivery pipe 45 is fixedly connected to the top of the liquid storage cylinder 44. The end of the delivery pipe 45 away from the liquid storage cylinder 44 passes through the carrier plate 41 and extends into the accommodating cavity 40. A pump valve 46 for delivery is fixedly provided on the delivery pipe 45. Specifically, in the utility model, the paint accumulated on the baffle 3 is cleaned in time through the design of the cleaning component to prevent the paint surface accumulated too thick from falling off due to drying, so as to ensure that the gas generator 4 sprays paint. The molding quality of the treatment is improved. By adjusting the design of the screw rod 2 33, the synchronous pulley 34, the synchronous belt 35 and the driving motor 4 37, the synchronous movement of the L-shaped sliders 31 on both sides of the baffle 3 is realized, so as to ensure the parallelism of the coating roller 38 and the scraper 43 during the radial movement, and improve the actual use effect of the device. Through the design of the coating roller 38, the electric cylinder 42 and the scraper 43, in the process of the radial movement of the L-shaped slider 31, the paint accumulated on the surface of the baffle 3 is subjected to the first step of chemical treatment through the paint remover stored inside the coating roller 38. After the paint remover has preliminarily decomposed and eliminated the paint, the electric cylinder 42 is started, driving the scraper 43 to push forward and conflict with the baffle 3, so that the scraper 43 follows the up and down movement of the L-shaped slider 31 to physically scrape off the paint accumulated on the surface of the baffle 3, and the cleaning of the paint accumulated on the surface of the baffle 3 can be completed. Through the design of the liquid storage cylinder 44, the delivery pipe 45 and the pump valve 46, the paint remover inside the coating roller 38 is replenished in time, effectively ensuring the normal operation of the cleaning component;
[0047] When it is necessary to clean the paint accumulated on the baffle 3, the driving motor 437 is first started to drive the coating roller 38 on the L-shaped slider 31 to move radially, and the paint remover stored in the coating roller 38 is applied to the surface of the baffle 3 through the extrusion between the coating roller 38 and the baffle 3. The coating roller 38 that is squeezed and deformed can be stretched and restored when it moves to the groove 39 at the bottom end of the baffle 3. After the paint remover has preliminarily decomposed and eliminated the paint, the electric cylinder 42 is started to drive the scraper 43 to push forward and contact the baffle 3, so that the scraper 43 physically scrapes off the paint accumulated on the surface of the baffle 3 during the process of following the L-shaped slider 31 to move downward, thereby completing the cleaning of the paint accumulated on the surface of the baffle 3;
[0048] When the paint remover in the coating roller 38 needs to be replenished, the staff starts the electric cylinder 42 to drive the scraper 43 to retract, and then starts the drive motor 437 to drive the coating roller 38 to move upward, so that the delivery pipe 45 is inserted into the coating roller 38 through the supporting plate 41, and then controls the pump valve 46 to start, so that the pump valve 46 extracts the paint remover stored in the liquid storage cylinder 44 and flows into the coating roller 38 through the delivery pipe 45, so as to complete the replenishment of the paint remover in the coating roller 38;
[0049] It should be noted that, in the present invention, the delivery pipe 45 is made of a stainless steel pipe that is not easily deformed. Through this design, the delivery pipe 45 can pass through the supporting plate 41 as usual and be placed in the coating roller 38 after the coating roller 38 moves up, so as to facilitate timely replenishment of the paint remover inside the coating roller 38. On the other hand, the scraper 43 controlled by the electric cylinder 42 retracts inward during the process of the coating roller 38 moving up, thereby avoiding unnecessary movement interference between the scraper 43 and the delivery pipe 45, thereby ensuring the normal operation of the cleaning component.
[0050] The use process of a paint spraying device for production of a gas generator 4 provided by the utility model is as follows:
[0051] When the staff puts the gas generator 4 into the placement tube 20, the bottom end of the gas generator 4 continuously presses the guide inclined plate 29, and the pressed guide inclined plate 29 drives the clamping strip 27 to press the compression spring 30, and is gradually placed into the placement tube 20 under the guidance of the guide inclined plate 29 and abuts against the side wall of the clamping strip 27. When the bottom end of the gas generator 4 abuts against the bottom wall of the placement tube 20, the clamping strip 27 always abuts against the outer wall of the gas generator 4 under the elastic force of the compression spring 30, thereby completing the restriction of the position of the gas generator 4 in the placement tube 20.
[0052] When the device is spraying paint on the gas generator 4 in the placement cylinder 20, the staff first adjusts the axial and radial parameters of the paint spraying component according to the specifications of the gas generator 4 through the cooperation between the electric slide rail 7, the drive motor 10, the adjusting screw 9 and the moving block 8, so that the paint spraying component is kept in the best paint spraying position, and then starts the drive motor 216 to make the sprocket 13 drive the chain 14 to move, thereby driving the slide 18 fixedly connected to the chain 14 to slide on the guide rail, so that the guide sleeve 19 at the top of the slide 18 performs annular movement, thereby realizing the annular conveyance of the placement cylinder 20 at the top of the guide sleeve 19, and when the placement cylinder 20 at the front end of the guide sleeve 19 is about to be separated from the spray of the paint spraying component When the paint range is reached, the drive motor 2 16 stops and the drive motor 3 26 starts, thereby driving the placement cylinder 20 to rotate through the sprocket 24, the chain 25 and the rotating shaft 23 inside the guide sleeve 19, so that the paint spraying assembly performs a comprehensive paint spraying treatment on the gas generator 4 placed in the placement cylinder 20. When the gas generator 4 located within the coverage range of the paint spraying assembly is painted, the drive motor 3 26 stops and the drive motor 2 16 starts, driving the painted gas generator 4 to be transported forward, and then the staff dries the paint surface of the gas generator 4 after the paint treatment or waits for the paint surface to dry naturally, then removes the gas generator 4, and places the gas generators 4 to be painted one by one into the placement cylinder 20;
[0053] When it is necessary to clean the paint accumulated on the baffle 3, the driving motor 437 is first started to drive the coating roller 38 on the L-shaped slider 31 to move radially, and the paint remover stored in the coating roller 38 is applied to the surface of the baffle 3 through the extrusion between the coating roller 38 and the baffle 3. The coating roller 38 that is squeezed and deformed can be stretched and restored when it moves to the groove 39 at the bottom end of the baffle 3. After the paint remover has preliminarily decomposed and eliminated the paint, the electric cylinder 42 is started to drive the scraper 43 to push forward and contact the baffle 3, so that the scraper 43 physically scrapes off the paint accumulated on the surface of the baffle 3 during the process of following the L-shaped slider 31 to move downward, thereby completing the cleaning of the paint accumulated on the surface of the baffle 3;
[0054] When it is necessary to replenish the paint remover in the coating roller 38, the staff starts the electric cylinder 42 to drive the scraper 43 to retract, and then starts the drive motor 437 to drive the coating roller 38 to move upward, so that the delivery pipe 45 is inserted into the coating roller 38 through the supporting plate 41, and then controls the pump valve 46 to start, so that the pump valve 46 extracts the paint remover stored in the liquid storage cylinder 44 and flows into the coating roller 38 through the delivery pipe 45, thereby completing the replenishment of the paint remover inside the coating roller 38.
