Description

Technical Field

[0001] This utility model relates to the field of ultrasonic spraying machine technology, specifically an automatic spraying device based on ultrasonic atomization and three-axis trajectory control. Background Technology

[0002] Ultrasonic spraying, also known as ultrasonic coating, is a spraying process that utilizes ultrasonic atomization technology. The material being sprayed is initially in a liquid state; the liquid can be a solution, sol, suspension, etc. The liquid coating is first atomized into fine particles by an ultrasonic atomizing device, and then uniformly coated onto the substrate surface with a certain amount of carrier gas, thereby forming a coating or film. Compared with traditional two-fluid spraying, ultrasonic spraying has advantages such as high coating uniformity, high material utilization rate, high precision in coating thickness control, thinner coating thickness, less spatter, and lower maintenance costs.

[0003] Currently, after the ultrasonic spraying machine is used, the nozzle area needs to be wiped by the staff. If the staff forgets to clean it, the paint residue on the nozzle will dry and adhere to the nozzle after a long time, affecting the next use, which has certain drawbacks. To address this, we propose an automatic spraying device based on ultrasonic atomization and three-axis trajectory control. Utility Model Content

[0004] The purpose of this invention is to provide an automatic spraying device based on ultrasonic atomization and three-axis trajectory control, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic spraying device based on ultrasonic atomization and three-axis trajectory control, comprising a body, a nozzle, and a three-axis control mechanism. The top of the body is equipped with a running indicator light, and the front of the body is equipped with a control panel, a temperature display panel, and a material feeding control panel. The interior of the body has a spraying chamber. The three-axis control mechanism consists of an X-axis drive cylinder, an X-axis guide rail, an X-axis slider, a Y-axis drive cylinder, a Y-axis guide rail, a Y-axis slider, and a Z-axis electric push rod. The bottom of the Y-axis slider is equipped with a cleaning device, which includes a control unit and a cleaning unit.

[0006] The cleaning unit includes:

[0007] Cleaning sponge: The cleaning sponge is used to wipe and clean the nozzles.

[0008] Hinged base, used to support the cleaning sponge;

[0009] The spring is used to control the cleaning sponge to automatically contact the nozzle when the hinge seat is not in contact with it.

[0010] Preferably, the X-axis guide rail is fixed to the inner wall of the spraying chamber. An X-axis drive cylinder is provided on the left side of the X-axis guide rail. The X-axis slider is slidably connected to the X-axis guide rail. The output shaft of the X-axis drive cylinder is fixed to the X-axis slider. The bottom of the X-axis slider is fixed to the top of the Y-axis guide rail. A Y-axis drive cylinder is provided on the front of the Y-axis guide rail. The output shaft of the Y-axis drive cylinder is fixed to the Y-axis slider. The Y-axis slider is slidably connected to the Y-axis guide rail. A Z-axis electric push rod is fixed to the bottom of the Y-axis slider. A mounting base is fixed to the bottom of the Z-axis electric push rod. A nozzle is provided at the bottom of the mounting base. The X-axis drive cylinder drives the Y-axis guide rail to move left and right. The Y-axis drive cylinder drives the Z-axis electric push rod to move the mounting base and nozzle back and forth. The Z-axis electric push rod drives the mounting base and nozzle to move up and down for spraying or retraction operations. Through the set three-axis control mechanism, precise spraying trajectory control is achieved. The nozzle is connected to the feeding device of the machine body through a material feeding hose. The material feeding and spraying operation is performed by a vacuum pump set inside the machine body.

[0011] Preferably, the control unit includes a fixed sleeve, the top of which is fixed to the bottom of the Y-axis slider. A groove is formed on the inner side of the fixed sleeve, and a threaded block is slidably installed on the inner side of the groove. A cylinder is rotatably installed on the inner side of the fixed sleeve, and the surface of the cylinder is threaded. The cylinder is threadedly connected to the threaded block. A spiral groove is formed on the inner side of the cylinder, and a slide rod is slidably installed on the inner side of the spiral groove. The end of the slide rod away from the spiral groove is fixed to the left side of the mounting base. When the Z-axis electric push rod drives the mounting base and nozzle to move up and down, the mounting base, carrying the slide rod, slides within the spiral groove, causing the cylinder to rotate. When the cylinder rotates, the threaded block can be controlled to move up and down.

[0012] Preferably, the hinge seat passes through and is hinged to the cylinder. A cleaning sponge is fixed to the top of the hinge seat, and a spring is fixed to the top of the hinge seat. The end of the spring is fixed to the inside of the cylinder away from the hinge seat. When the threaded block moves downward, the Z-axis electric push rod drives the mounting seat and nozzle to move upward. The threaded block abuts against the hinge seat, pushing the hinge seat to swing at the position hinged to the cylinder. The hinge seat, carrying the cleaning sponge, moves upward and contacts the bottom of the nozzle. As the cylinder rotates a certain angle, the cylinder drives the hinge seat and the cleaning sponge to rotate together. The cleaning sponge can automatically clean the bottom of the nozzle. At this time, when the threaded block continues to move downward, the hinge seat cooperates with the nozzle to squeeze the soft cleaning sponge, which will not affect the normal downward movement of the threaded block. No manual cleaning is required, avoiding the situation where the paint adheres to the nozzle due to the staff forgetting to clean it, which will affect the normal use next time.

[0013] Compared with the prior art, this utility model provides an automatic spraying device based on ultrasonic atomization and three-axis trajectory control, which has the following beneficial effects:

[0014] 1. This automatic spraying equipment based on ultrasonic atomization and three-axis trajectory control, through a cleaning device, when the Z-axis electric push rod drives the mounting base and nozzle to move upward and retract, the cylinder rotates, controlling the threaded block to move downward. The threaded block abuts against the hinge seat, pushing the hinge seat to swing at the hinge position with the cylinder. The hinge seat, carrying the cleaning sponge, moves upward and contacts the bottom of the nozzle. As the cylinder rotates at a certain angle, the cylinder drives the hinge seat and the cleaning sponge to rotate together, and the cleaning sponge can automatically clean the bottom of the nozzle without the need for manual cleaning by the staff. This avoids the situation where the paint adheres to the nozzle due to the staff forgetting to clean it, which will affect the normal use next time.

[0024] like Figures 1-7 As shown, this utility model provides a technical solution: an automatic spraying device based on ultrasonic atomization and three-axis trajectory control, including a body 1, a nozzle 2 and a three-axis control mechanism 5. The top of the body 1 is provided with a running indicator light 6, and the front of the body 1 is provided with a control panel 7, a temperature display panel 8 and a feeding control panel 9. The interior of the body 1 is provided with a spraying chamber 10. The three-axis control mechanism 5 is composed of an X-axis drive cylinder 51, an X-axis guide rail 52, an X-axis slider 53, a Y-axis drive cylinder 54, a Y-axis guide rail 55, a Y-axis slider 56 and a Z-axis electric push rod 57. The bottom of the Y-axis slider 56 is provided with a cleaning device, which includes a control part 3 and a cleaning part 4. The cleaning part 4 includes a cleaning sponge 41, a hinge seat 42 and a spring piece 43.

[0025] X-axis guide rail 52 is fixed to the inner wall of spraying chamber 10. An X-axis drive cylinder 51 is located on the left side of X-axis guide rail 52. An X-axis slider 53 is slidably connected to X-axis guide rail 52. The output shaft of X-axis drive cylinder 51 is fixed to X-axis slider 53. The bottom of X-axis slider 53 is fixed to the top of Y-axis guide rail 55. A Y-axis drive cylinder 54 is located on the front of Y-axis guide rail 55. The output shaft of Y-axis drive cylinder 54 is fixed to Y-axis slider 56. Y-axis slider 56 is slidably connected to Y-axis guide rail 55. A Z-axis electric push rod 57 is fixed to the bottom of Y-axis slider 56. A mounting base 11 is fixed to the bottom of Z-axis electric push rod 57. A nozzle 2 is located at the bottom of mounting base 11. The stroke of X-axis guide rail 52 is 250mm. The stroke of the Z-axis electric push rod 57 is 100mm, and the X-axis drive cylinder 51 drives the Y-axis guide rail 55 to move left and right. The Y-axis drive cylinder 54 drives the Z-axis electric push rod 57 to move the mounting base 11 and nozzle 2 back and forth. The Z-axis electric push rod 57 drives the mounting base 11 and nozzle 2 to move up and down for spraying or retraction. The three-axis control mechanism 5 is set to achieve precise spraying trajectory control. The nozzle 2 is connected to the feeding device of the machine body 1 through the feeding hose. The vacuum pump set inside the machine body 1 is used for feeding and spraying operations. (Ultrasonic spraying machines have mature existing products, and their specific working principle belongs to the existing disclosed technology. Therefore, it is not described in detail in this application.)

[0026] The control unit 3 includes a fixed sleeve 31, the top of which is fixed to the bottom of the Y-axis slider 56. A groove 32 is provided on the inner side of the fixed sleeve 31, and a threaded block 33 is slidably installed on the inner side of the groove 32. A cylinder 34 is rotatably installed on the inner side of the fixed sleeve 31. The surface of the cylinder 34 is threaded, and the cylinder 34 is threadedly connected to the threaded block 33. A spiral groove 35 is provided on the inner side of the cylinder 34, and a slide rod 36 is slidably installed on the inner side of the spiral groove 35. The end of the slide rod 36 away from the spiral groove 35 is fixed to the left side of the mounting base 11. When the Z-axis electric push rod 57 drives the mounting base 11 and the nozzle 2 to move up and down, the mounting base 11 slides the slide rod 36 in the spiral groove 35, and the cylinder 34 can rotate. When the cylinder 34 rotates, the threaded block 33 can be controlled to move up and down.

[0027] The hinge seat 42 passes through and is hinged to the cylinder 34. A cleaning sponge 41 is fixed to the top of the hinge seat 42, and a spring piece 43 is also fixed to the top of the hinge seat 42. The end of the spring piece 43 away from the hinge seat 42 is fixed to the inside of the cylinder 34. When the threaded block 33 moves downward, the Z-axis electric push rod 57 drives the mounting seat 11 and the nozzle 2 to move upward. The threaded block 33 abuts against the hinge seat 42, pushing the hinge seat 42 to swing at the position hinged to the cylinder 34. The hinge seat 42 moves upward with the cleaning sponge 41. The cylinder 34 rotates at a certain angle, and the cylinder 34 drives the hinge seat 42 and the cleaning sponge 41 to rotate together. The cleaning sponge 41 can automatically clean the bottom of the nozzle 2. At this time, when the threaded block 33 continues to move downward, the hinge seat 42 cooperates with the nozzle 2 to squeeze the soft cleaning sponge 41. This will not affect the normal downward movement of the threaded block 33. There is no need for manual cleaning by the staff, which avoids the situation where the staff forgets to clean it, resulting in the paint adhering to the nozzle 2 and affecting the normal use next time.

[0028] In this invention, when in use, the machine body 1 is opened, the workpiece is placed into the spraying chamber 10, and heated by the vacuum heating adsorption platform inside the spraying chamber 10. The X-axis drive cylinder 51 drives the Y-axis guide rail 55 to move left and right, the Y-axis drive cylinder 54 drives the Z-axis electric push rod 57 to move the mounting base 11 and nozzle 2 back and forth, and the Z-axis electric push rod 57 drives the mounting base 11 and nozzle 2 to move up and down for spraying or retraction. Through the three-axis control mechanism 5, precise spraying trajectory control is achieved.

[0029] During spraying, the Z-axis electric push rod 57 drives the mounting base 11 and nozzle 2 to move downward. The mounting base 11, along with the slide rod 36, slides within the spiral groove 35, causing the cylinder 34 to rotate. At this time, the threaded block 33 moves upward and no longer contacts the hinge seat 42. Under the action of the spring piece 43, the hinge seat 42 swings downward with the cleaning sponge 41, so that the cleaning sponge 41 no longer contacts the nozzle 2. During the downward movement, the nozzle 2 contacts the soft cleaning sponge 41, causing the cleaning sponge 41 to deform. This does not affect the normal downward movement of the nozzle 2 for spraying operations.

[0030] After spraying is completed, the Z-axis electric push rod 57 drives the mounting base 11 and nozzle 2 to move upward, the cylinder 34 rotates in the opposite direction, the threaded block 33 moves downward, and the threaded block 33 abuts against the hinge seat 42, pushing the hinge seat 42 to swing at the hinge position with the cylinder 34. The hinge seat 42, carrying the cleaning sponge 41, moves upward and contacts the bottom of the nozzle 2. As the cylinder 34 rotates at a certain angle, the cylinder 34 drives the hinge seat 42 and the cleaning sponge 41 to rotate together. The cleaning sponge 41 can automatically clean the bottom of the nozzle 2. At this time, when the threaded block 33 continues to move downward, the hinge seat 42 cooperates with the nozzle 2 to squeeze the soft cleaning sponge 41, which will not affect the normal downward movement of the threaded block 33. No manual cleaning is required, avoiding the situation where the paint adheres to the nozzle 2 due to the staff forgetting to clean it, which will affect the normal use next time.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
