Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to automobile parts spraying equipment. Background Art

[0002] Spraying is a surface treatment technology that uses a spray gun or a disc atomizer to disperse the paint into uniform and fine droplets with the help of pressure or centrifugal force, and then applies it to the surface of the object. Spraying technology has a wide range of applications, including but not limited to automobile manufacturing, furniture manufacturing, construction, aerospace, electronics and other industries.

[0003] Auto parts are the various units that make up the whole car and the products that serve the car. There are many types of auto parts, covering various systems and components of the car. Spraying is an important process step in automobile manufacturing and maintenance. It involves applying one or more layers of paint to the surface of the car or its parts to achieve multiple purposes such as protection, decoration and identification.

[0004] At present, automobile parts include various metal components of different sizes and different rules. When spraying some special automobile parts, such as the tailgate, which is an important equipment installed at the rear of trucks and various vehicles, the tailgate will use metal plates bent at a certain angle, such as the attached Fig.11 As shown, because there are multiple straight lines with different angles in the spraying of the metal plate, it is difficult for the nozzle to maintain a fixed spraying angle, spraying height and moving speed during the entire spraying process, which can easily cause uneven spraying thickness and reduce the spraying quality.

DETAILED DESCRIPTION

Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0049] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0050] like Figures 1 to 12 As shown, an automobile parts spraying equipment of the present invention includes: a machine platform 1, a U-shaped plate 2, the U-shaped plate 2 is fixedly installed on the top of the machine platform 1, a metal plate 8, the metal plate 8 is composed of a horizontal plate and an inclined plate, and a certain angle is formed between the horizontal plate and the inclined plate, a spraying mechanism 3 for spraying the metal plate 8, a driving mechanism 4 for driving the spraying mechanism 3 to perform horizontal movement spraying, a height adjustment mechanism 5 for adjusting the spraying height of the spraying mechanism 3, an angle adjustment mechanism 6 for adjusting the spraying angle of the spraying mechanism 3, and a rotating mechanism 7 for driving the spraying mechanism 3 to perform horizontal rotation spraying.

[0051] When the metal plate 8 is sprayed, the metal plate 8 is first placed at a designated position on the top of the machine table 1. Since the metal plate 8 has two straight lines at different angles, namely the horizontal plate and the inclined plate (as shown in the attached figure), Fig.11 As shown in the figure), the spraying mechanism 3 first sprays the horizontal plate and then sprays the inclined plate; when the driving mechanism 4 drives the spraying mechanism 3 to spray the metal plate 8, the spraying height of the spraying mechanism 3 is adjusted by the height adjustment mechanism 5, so that the spraying distance between the spraying mechanism 3 and the straight surface of the metal plate 8 is always consistent, thereby improving the uniformity of spraying and improving the spraying quality; the spraying angle of the spraying mechanism 3 is adjusted by the angle adjustment mechanism 6, so that the spraying mechanism 3 and the straight surfaces of different angles are always kept in a vertical state, thereby further improving the uniformity of spraying and improving the spraying quality.

[0052] In addition, when it is necessary to spray other automobile parts, such as spraying the inner wall of a pipe, the spraying mechanism 3 is adjusted to a posture perpendicular to the inner wall of the pipe through the angle adjustment mechanism 6. At this time, the spraying mechanism 3 can be driven to rotate horizontally in a circle by starting the rotating mechanism 7, so that the inner wall of the pipe can be sprayed.

[0053] At this time, the spraying height of the spraying mechanism 3 can be adjusted by the height adjustment mechanism 5, so as to adapt to the spraying of pipes of different depths, thereby improving the versatility of the present invention.

[0054] The driving mechanism 4 includes: a fixed plate 41 fixedly installed on the top of the inner cavity of the U-shaped plate 2, a threaded rod 42 rotatably installed on the side wall of the fixed plate 41, a power source 43 for driving the threaded rod 42 to rotate, a moving seat 44 that moves axially along the threaded rod 42, the moving seat 44 is threadedly installed on the outer edge of the threaded rod 42, and a limit rod 45 is used to guide and limit the moving seat 44 when it moves. Two limit rods 45 are provided and symmetrically penetrate the side wall of the moving seat 44. Both ends of the two limit rods 45 are fixedly installed on the side walls of the adjacent fixed plate 41.

[0055] When the metal plate 8 is to be sprayed, the metal plate 8 is placed at a designated position on the top of the machine 1. At this time, the power source 43 is started to drive the threaded rod 42 to rotate, and the threaded rod 42 drives the movable seat 44 to move. The limit rod 45 is set to guide and limit the movable seat 44 to prevent the movable seat 44 from rotating with the threaded rod 42, so that the movable seat 44 moves along the axial direction of the threaded rod 42, thereby driving the spraying mechanism 3 to move, so that the metal plate 8 can be sprayed.

[0056] Since the metal plate 8 has two straight surfaces at different angles, the nozzle 31 first sprays horizontally and then sprays at an angle. To ensure uniform spraying thickness, the nozzle 31 slides over the horizontal plate and the inclined plate at a consistent speed, but the moving direction of the movable seat 44 is horizontal. Therefore, the speed of the movable seat 44 when passing over the horizontal plate is greater than the height when passing over the inclined plate. Therefore, when the movable seat 44 passes over the horizontal plate, the power source four 43 rotates faster, and when the movable seat 44 passes over the inclined plate, the power source four 43 rotates slower, thereby achieving the consistency of the speed at which the nozzle 31 slides over the horizontal plate and the inclined plate, thereby ensuring uniform spraying thickness of the metal plate 8.

[0057] It is to be added here that the power source four 43 is preferably: an electric motor.

[0058] The height adjustment mechanism 5 includes: an installation box 51 fixedly installed at the bottom of the movable seat 44, a threaded shaft 52 rotatably installed on the side wall of the installation box 51, a power source 53 for driving the threaded shaft 52 to rotate, the power source 53 is installed in the inner cavity of the installation box 51 and a threaded tube 54 moves axially along the threaded shaft 52, the threaded tube 54 is threadedly installed on the outer edge of the threaded shaft 52, and a limiting unit 55 is used to guide and limit the threaded tube 54 when it moves.

[0059] When the metal parts are sprayed, the power source 53 is started to drive the threaded shaft 52 to rotate, and the threaded shaft 52 is guided and limited by the limit unit 55, so that the threaded shaft 52 can drive the threaded tube 54 to move up and down when it rotates, thereby driving the spraying mechanism 3 to move up and down, and then it is convenient to adjust the spraying height of the spraying mechanism 3 according to the spraying needs, so that the spraying mechanism 3 always maintains the same height when spraying different surfaces of the metal plate 8, thereby improving the uniformity of the spraying and improving the spraying quality.

[0060] It is to be added here that the power source five 53 is preferably: an electric motor.

[0061] The limiting unit 55 includes: a fixed tube 551 fixedly installed at the bottom of the installation box 51 and sleeved on the outer edge of the threaded tube 54, a limiting groove opened on the inner wall of the fixed tube 551, and a slide bar 552 fixedly installed on the outer side of the threaded tube 54 and sliding in the inner cavity of the limiting groove.

[0062] When the threaded tube 54 moves, it can drive the slide bar 552 to slide in the inner cavity of the limiting groove. Through the mutual cooperation between the slide bar 552 and the limiting groove, the threaded tube 54 can be guided and limited to prevent the threaded tube 54 from rotating with the threaded shaft 52, so that the threaded tube 54 maintains movement in a straight line direction.

[0063] The angle adjustment mechanism 6 includes: a mounting plate 61 rotatably mounted on the bottom end of the threaded tube 54, a rotating rod 62 rotatably mounted on the side wall of the mounting plate 61, a power source 63 for driving the rotating rod 62 to rotate, a linkage gear 64 that rotates as the rotating rod 62 rotates, a transmission gear 65 that is fixedly sleeved on the outer edge of the rotating rod 62 and meshed with the linkage gear 64, the transmission gear 65 is a half gear and is rotatably mounted on the inner wall of the mounting plate 61, and a linkage plate 66 that is fixedly mounted on the bottom of the transmission gear 65.

[0064] When the metal plate 8 is sprayed, the spraying mechanism 3 first sprays the horizontal plate, and then sprays the inclined plate. When the spraying mechanism 3 sprays the inclined surface of the metal plate 8, the spraying angle needs to be adjusted first, that is, by starting the power source 63 to drive the rotating rod 62 to rotate, the rotating rod 62 drives the linkage gear 64 to rotate, the linkage gear 64 drives the transmission gear 65 to rotate, and the transmission gear 65 can drive the linkage plate 66 to rotate, thereby driving the spraying mechanism 3 to deflect, thereby realizing the angle adjustment of the spraying mechanism 3, so that the spraying mechanism 3 and the straight line surfaces of different angles are always kept in a vertical state, thereby further improving the uniformity of spraying and improving the spraying quality;

[0065] It is to be added here that the power source six 63 is preferably: a motor.

[0066] Through the mutual cooperation of the driving mechanism 4, the height adjustment mechanism 5 and the angle adjustment mechanism 6, on the one hand, it is convenient to adjust the spraying height of the spraying mechanism 3 according to the spraying needs, so that the spraying mechanism 3 always maintains the same height when spraying different surfaces of the metal plate 8, thereby improving the uniformity of spraying and improving the spraying quality. On the other hand, the angle adjustment of the spraying mechanism 3 is realized, so that the spraying mechanism 3 and the straight lines at different angles are always kept in a vertical state, thereby further improving the uniformity of spraying and improving the spraying quality. At the same time, the speed at which the nozzle 31 slides over the horizontal plate and the inclined plate is consistent, ensuring the uniform thickness of the metal plate 8 sprayed; the problem that because there are multiple straight lines at different angles in the spraying of the automobile parts, it is difficult for the nozzle 31 to maintain a fixed spraying angle, spraying height and moving speed during the entire spraying process, which easily causes uneven spraying thickness and reduces the spraying quality is solved.

[0067] The spraying mechanism 3 includes: a nozzle 31 for spraying the metal plate 8, a conveying component 32 for conveying the coating to the nozzle 31, a replacement component 33 for automatically replacing the nozzle 31, a cleaning component 34 for cleaning the nozzle 31 after use, and an anti-drip component 35 for preventing the nozzle 31 from dripping after use; the conveying component 32 includes: a storage box 321 for storing the coating, the storage box 321 is fixedly installed on the top of the linkage plate 66, a pump body 1 for absorbing the coating in the storage box 321, the pump body 1 is located in the inner cavity of the storage box 321, a telescopic tube 1322 fixedly installed with the pump body 1, a power source 1323 for driving the telescopic tube 1322 to extend and retract, and a movable plate 1324 fixedly installed on the bottom end of the power source 1323 and the side wall of the telescopic tube 1322.

[0068] After the metal plate 8 is placed, it is necessary to transport the coating material to the nozzle 31 through the conveying component 32 to spray the metal plate 8. At this time, the telescopic tube 322 is first docked with the nozzle 31, that is, by starting the power source 323, the movable plate 324 can be driven to move downward, and the movable plate 324 drives the telescopic tube 322 to move downward, thereby driving the anti-drip component 35 to operate. Through the mutual cooperation with the anti-drip component 35, the docking of the telescopic tube 322 and the nozzle 31 can be completed. After the docking of the telescopic tube 322 and the nozzle 31 is completed, by starting the pump body 1, the coating material in the inner cavity of the storage box 321 can be sucked and enters the nozzle 31 through the telescopic tube 322, and the coating material is sprayed out through the nozzle 31, thereby realizing that the coating material can be automatically transported to the nozzle 31 when spraying the metal plate 8;

[0069] It should be added here that the power source 323 is preferably a cylinder, so as to facilitate the movement of the movable plate 324 up and down.

[0070] The drip-proof component 35 includes: a mounting seat 351 fixedly mounted on the outer edge of the nozzle 31, a connecting groove 355 provided at the center of the top of the mounting seat 351, the connecting groove 355 and the nozzle 31 are mutually connected, mounting grooves provided on both sides of the top of the mounting seat 351, a protective plate 352 for protecting the connecting groove 355, two protective plates 352 are provided, and slide on the top of the mounting seat 351, and the sides of the tops of the two protective plates 352 that are close to each other are both set as arc surfaces, a movable plate 353 fixedly mounted on the side wall of the protective plate 352 and sliding in the inner cavity of the mounting groove, a capsule 354 fixedly mounted between the side wall of the movable plate 353 and the inner wall of the mounting groove, a conduit 356 inserted between the side wall of the capsule 354 and the side wall of the nozzle 31, and a reset unit 357 for driving the protective plate 352 to reset.

[0071] When the nozzle 31 is not in use, the two protective plates 352 are tightly fitted on the adjacent sides, so that the two protective plates 352 seal the top of the connecting groove 355, thereby achieving dust protection for the nozzle 31 and preventing dust from entering the inner cavity of the nozzle 31 from the connecting groove 355 when the nozzle 31 is not in use, causing clogging of the nozzle 31 and affecting the spraying effect.

[0072] When the nozzle 31 is in use, the bottom end of the telescopic tube 322 moves downward and abuts against the arc-shaped surfaces of the two protective plates 352, thereby driving the two protective plates 352 to move away from each other. By moving the two protective plates 352 away from each other, the bottom end of the telescopic tube 322 is inserted into the inner cavity of the connecting groove 355, thereby completing the connection with the nozzle 31; at the same time, the adjacent movable plate 353 is driven to move by the protective plate 352, and the capsule 354 can be squeezed by the protective plate 352. At this time, the air inside the capsule 354 is squeezed and blown into the inner cavity of the nozzle 31 through the conduit 356, and the air is discharged through the bottom end of the nozzle 31, thereby playing a role in dust removal for the nozzle 31, avoiding dust adhering to the bottom end of the nozzle 31 and affecting the spraying effect, and further improving the role of dust protection for the nozzle 31; when the connection of the nozzle 31 is completed, the spraying mechanism 3 is started at this time, and the metal plate 8 can be sprayed.

[0073] Through the cooperation between the protective plate 352 and the capsule 354, the nozzle 31 can be provided with a double dust protection, thereby ensuring the cleanliness of the nozzle 31 and improving the spraying effect and quality of the metal plate 8.

[0074] In addition, when the movable plate 353 moves, the reset unit 357 can be driven to operate. The reset unit 357 includes: a slide groove provided at the bottom of the inner cavity of the installation groove, a slider 3571 fixedly mounted on the movable plate 353 and sliding in the inner cavity of the slide groove, and a guide rod 3572 installed on the side wall of the slider 3571. Both ends of the guide rod 3572 are fixedly installed on the inner wall of the slide groove. Through the setting of the guide rod 3572, on the one hand, the slider 3571 can be limited and guided, and on the other hand, the slider 3571 can be prevented from separating from the slide groove, and the reset spring 3573 that drives the protective plate 352 to reset can be driven. One end of the reset spring 3573 is fixedly installed on the side wall of the slider 3571, and the other end is fixedly installed on the inner wall of the slide groove; when the two movable plates 353 move away from each other, the adjacent sliders 3571 can be driven to move, and the sliders 3571 drive the adjacent reset springs 3573 to be compressed.

[0075] When the nozzle 31 is used and needs to be replaced with another different nozzle 31 for spraying, starting the power source 323 can drive the movable plate 324 to move upward, and the movable plate 324 drives the telescopic tube 322 to move upward, so that the bottom end of the telescopic tube 322 is separated from the inner cavity of the connecting groove 355. At this time, through the elastic force of the reset spring 3573, the adjacent slider 3571 can be driven to reset, the slider 3571 drives the adjacent movable plate 353 to reset, and the movable plate 353 drives the adjacent protective plate 352 to reset. At the same time, since the capsule 354 itself has a certain elasticity, the capsule 354 can also drive the movable plate 353 to reset when it is restored, and then drive the adjacent protective plate 352 to reset.

[0076] In this process, the capsule 354 and the reset spring 3573 cooperate with each other to jointly drive the protective plate 352 to reset, so that the protective plate 352 is reset under the action of double elastic force, thereby making the two protective plates 352 fit tightly, and the sealing effect of the connecting groove 355 is good.

[0077] Since the capsule 354 is squeezed during the use of the nozzle 31, the air inside it is discharged. When the capsule 354 is restored, the coating remaining in the inner cavity of the nozzle 31 can be sucked into the inner cavity of the capsule 354 through the catheter 356, which effectively solves the problem of pollution caused by dripping of the coating remaining in the nozzle 31.

[0078] In summary, it can be seen that through the mutual cooperation between the capsule 354 and the protective plate 352, the nozzle 31 can be provided with a double dustproof protection, the cleanliness of the nozzle 31 is ensured, and the spraying effect and the spraying quality of the metal plate 8 are improved; and through the mutual cooperation between the capsule 354 and the reset spring 3573, the protective plate 352 can be jointly driven to reset, so that the reset of the protective plate 352 is subjected to a double elastic force, thereby making the two protective plates 352 fit tightly, and the sealing effect of the connecting groove 355 is good; at the same time, when the capsule 354 is squeezed, the air can be discharged to remove dust from the nozzle 31. When the capsule 354 is restored, the coating remaining in the inner cavity of the nozzle 31 can be sucked into the inner cavity of the capsule 354 through the conduit 356, which effectively solves the problem of pollution caused by the dripping of the coating remaining in the nozzle 31.

[0079] The replacement component 33 includes: a rotating shaft 332 rotatably mounted on the side wall of the linkage plate 66, a power source 331 driving the rotating shaft 332 to rotate, and a rotating plate 333 fixedly mounted at the bottom end of the rotating shaft 332, and both sides of the rotating plate 333 are fixedly connected to the adjacent mounting seat 351.

[0080] When it is necessary to replace other different nozzles 31 for spraying, starting the power source three 331 can drive the rotating shaft 332 to rotate, and the rotating shaft 332 drives the rotating plate 333 to rotate, and the rotating plate 333 drives the two mounting seats 351 to interchange the positions, so that the two nozzles 31 can be interchanged, thereby realizing automatic replacement of the nozzles 31, and there is no need to manually replace the nozzles 31, thereby improving replacement efficiency.

[0081] It is to be added here that the power source three 331 is preferably: a motor.

[0082] The cleaning assembly 34 includes: a liquid storage tank 341 for storing cleaning liquid, the liquid storage tank 341 is fixedly installed on the top of the linkage plate 66, a pump body 2 for absorbing the cleaning liquid in the liquid storage tank 341, the pump body 2 is located in the inner cavity of the liquid storage tank 341, a telescopic tube 2 342 fixedly installed with the pump body 2, a power source 2 343 for driving the telescopic tube 2 342 to be extended and retracted, and a movable plate 2 344 fixedly installed on the bottom end of the power source 2 343 and the side wall of the telescopic tube 2 342.

[0083] When the used spray head 31 moves to the bottom of the telescopic rod 742, the second power source 343 is started to drive the second movable plate 344 to move downward, and the second movable plate 344 drives the second telescopic tube 342 to move downward, thereby driving the anti-drip assembly 35 to operate, and the second telescopic tube 342 can be connected to the used spray head 31 through the cooperation with the anti-drip assembly 35;

[0084] When the expansion tube 342 is connected to the nozzle 31, the capsule 354 is squeezed again, and the coating inside it is squeezed into the inner cavity of the nozzle 31. At this time, the pump body 2 is started to absorb the cleaning liquid in the liquid storage tank 341 and transport it to the nozzle 31 through the expansion tube 342, so that the residual coating in the nozzle 31 can be rinsed clean, and the replaced nozzle 31 can be cleaned to prevent the residual coating in the nozzle 31 from solidifying easily, causing uneven spraying and affecting the subsequent spraying effect.

[0085] It is to be added here that the second power source 343 is preferably: a cylinder, so as to facilitate the movement of the second movable plate 344 up and down.

[0086] Through the cooperation between the replacement component 33 and the cleaning component 34, the nozzle 31 is automatically replaced without manual replacement, which improves the replacement efficiency and cleans the replaced nozzle 31 to prevent the residual coating in the nozzle 31 from solidifying easily, causing uneven spraying and affecting the subsequent spraying effect.

[0087] The rotating mechanism 7 includes: a driven gear 73 rotatably mounted on the outer edge of the fixed tube 551, a driving gear 71 meshing with the driven gear 73, a power source 72 driving the driving gear 71, and a telescopic rod 74 fixedly mounted between the bottom of the driven gear 73 and the top of the mounting plate 61.

[0088] When it is necessary to spray other automobile parts, such as spraying the inner wall of the pipe, the spray mechanism 3 is adjusted to be perpendicular to the inner wall of the pipe through the angle adjustment mechanism 6, and the rotating mechanism 7 is started, that is, the driving gear 71 can be driven to rotate by starting the power source 72, the driving gear 71 drives the driven gear 73 to rotate, the driven gear 73 drives the telescopic rod 74 to rotate, the telescopic rod 74 drives the mounting plate 61 to rotate, and then the spray mechanism 3 can be driven to rotate in a horizontal circle, so that the inner wall of the pipe can be sprayed;

[0089] At this time, the spraying height of the spraying mechanism 3 can be adjusted by the height adjustment mechanism 5, so as to adapt to the spraying of pipes of different depths, thereby improving the versatility of the present invention.

[0090] It is to be added here that the power source 72 is preferably: an electric motor.

[0091] The control mechanism also includes: a controller, an angle measuring instrument for measuring the angle between the metal plate 8 and a distance meter for measuring the size of the metal plate 8 and the spraying distance of the nozzle 31; the controller is electrically connected to the angle measuring instrument and the distance meter respectively;

[0092] The metal plate 8 is composed of a horizontal plate and an inclined plate;

[0093] The steps for spraying the metal plate 8 are as follows:

[0094] Step S1, placing the metal plate 8 at a designated position on the top of the machine platform 1;

[0095] Step S2, using an angle measuring instrument to measure the angle α between the horizontal plate and the inclined plate in the metal plate 8; when spraying the metal plate 8, the spraying mechanism 3 first sprays the horizontal plate and then sprays the inclined plate. When the nozzle 31 finishes spraying the horizontal plate, when spraying the inclined surface of the metal plate 8, the spraying angle needs to be adjusted first. According to the angle α measured by the angle measuring instrument, the power source 63 is started to drive the rotating rod 62 to rotate, the rotating rod 62 drives the linkage gear 64 to rotate, the linkage gear 64 drives the transmission gear 65 to rotate, and the transmission gear 65 can drive the linkage plate 66 to rotate, thereby driving the spraying mechanism 3 to deflect (180-α) degrees, thereby realizing the angle adjustment of the spraying mechanism 3, so that the spraying mechanism 3 and the straight line surfaces of different angles are always kept in a vertical state, thereby further improving the uniformity of the spraying and improving the spraying quality; wherein the angle measuring instrument is preferably: a laser angle measuring instrument;

[0096] Step S3, measuring the length L1 of the horizontal plate and the length L2 of the inclined plate in the metal plate 8 by a distance meter; wherein the distance meter is preferably a laser measuring instrument, and when spraying, the distance meter can also measure the spraying distance between the nozzle 31 and the metal plate 8, and adjust it by the height adjustment mechanism 5, that is, by starting the power source 53 to drive the threaded shaft 52 to rotate, and by the guide limit unit 55 of the threaded shaft 52, when the threaded shaft 52 rotates, it can drive the threaded tube 54 to move up and down, thereby driving the spraying mechanism 3 to move up and down, and then it is convenient to adjust the spraying height of the spraying mechanism 3 according to the spraying needs, so that the spraying mechanism 3 always maintains the same height when spraying different surfaces of the metal plate 8, thereby improving the uniformity of spraying and improving the spraying quality.

[0097] Step S4, setting the spraying speed V1 of the nozzle 31 at the length L1 of the horizontal plate and the length L2 of the inclined plate through the controller;

[0098] Step S5, calculating the horizontal moving distance L3 of the moving seat 44 on the length L2 of the inclined plate, that is, L3 = cos(180°- a)*L2;

[0099] Step S6, calculating the time T required for the nozzle 31 to slide over the length L2 of the inclined plate, that is, T = L2 / V1;

[0100] Step S7, calculating the moving speed V2 required for the moving seat 44 to move the distance L3 when the nozzle 31 maintains the forward state V1, that is, V2=cos(180°-a)*V1;

[0101] Step S8, when the nozzle 31 maintains the forward state of V1, the moving speed V1 of the moving seat 44 in L1 and the moving speed V2 of L3 are set by the controller; the controller is electrically connected to the power source four 43, and the controller controls the start of the power source four 43, which can drive the threaded rod 42 to rotate, and the threaded rod 42 drives the moving seat 44 to move along the axial direction of the threaded rod 42, and then drives the spraying mechanism 3 to move, so that the metal plate 8 can be sprayed; because the metal plate 8 has two straight surfaces at different angles, the nozzle 31 first sprays horizontally and then sprays at an angle To ensure uniform thickness of spraying, the speed of the nozzle 31 sliding over the horizontal plate and the inclined plate is consistent, but the moving direction of the moving seat 44 is horizontal, so the speed of the moving seat 44 when passing over the horizontal plate is greater than the height when passing over the inclined plate. Therefore, when the moving seat 44 passes over the horizontal plate, the controller controls the power source four 43 to rotate faster, and when the moving seat 44 passes over the inclined plate, the controller controls the power source four 43 to rotate slower, thereby achieving the consistency of the speed of the nozzle 31 sliding over the horizontal plate and the inclined plate, ensuring uniform thickness of the spraying of the metal plate 8.
