Description

Technical Field

[0001] The present invention relates to the technical field of automotive processing equipment, and more specifically, to an adjustable intelligent spraying equipment for new energy vehicle parts. Background Art

[0002] New energy vehicles refer to vehicles that adopt new power systems and use clean energies such as electric energy and hydrogen energy to replace traditional fuels. Their core technologies cover batteries, motors, and electronic control systems, and they have characteristics such as zero emissions, low energy consumption, and intelligence. They are regarded as the core direction of the transformation and upgrading of the global automotive industry. Currently, the development of new energy vehicles has entered a period of rapid growth. With the breakthrough of solid-state battery and intelligent network connection technologies, new energy vehicles will evolve towards higher energy efficiency and deeper intelligence, becoming an important carrier of the global energy revolution.

[0003] The manufacturing process of new energy vehicles integrates traditional stamping, welding, painting, general assembly, and new power system integration technologies. Among them, the stamping process forms lightweight body panels through aluminum alloy or carbon fiber materials, the welding process ensures the sealing of the battery pack with high-precision laser welding, and the general assembly link requires strict integration of the battery, motor, and thermal management system. As the core link to ensure corrosion resistance and appearance, the painting process requires special treatment for many new energy vehicle parts. For example, the battery housing needs to be degreased, cleaned, and pretreated with chromium-free passivation, and then an anti-corrosion primer is formed through electrophoretic coating. Then, a waterborne coating is electrostatically sprayed, and an anti-chip intermediate coat, a high-gloss top coat, and an anti-ultraviolet clear coat are superimposed. Finally, it is baked and cured at 140 - 180 °C.

[0004] In the manufacturing of new energy vehicles, the spraying of complex curved parts is one of the technical difficulties. Components such as streamlined body panels, aerodynamic fairings, and irregular-shaped battery pack housings are usually composed of multi-curvature curves, with complex surface geometries and irregular structures such as depressions, protrusions, and corners. Existing spraying technologies face significant limitations in practical applications: traditional spraying equipment has insufficient degrees of freedom of movement and can usually only perform planar spraying around the left and right sides of the parts, resulting in weak coverage of multi-angle curved surfaces. During spraying, it is difficult for the spray gun angle and distance to dynamically adapt to the curvature changes, easily causing problems such as uneven coating thickness, missed spraying, or material waste in overlapping spraying areas. Manual supplementary spraying is required multiple times, reducing the efficiency by more than 30%, and the quality stability is difficult to guarantee.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes an adjustable intelligent spraying equipment for new energy vehicle parts. Summary of the Invention

The top end of the measuring sleeve is fixedly connected to the bottom of the displacement guide block; A displacement sensor, which is fixedly connected inside the measuring sleeve and is used to obtain the displacement change of the contact rod during the working process in real time.

[0009] Preferably, an amplification lever is rotatably connected in the inner cavity of the measuring sleeve. The short arm of the amplification lever is in contact and cooperation with the top end of the contact rod extending into the measuring sleeve. The displacement sensor is located on the inner side wall of the measuring sleeve to measure the horizontal displacement of the end of the long arm of the amplification lever.

[0010] Preferably, the displacement guide block is an electric telescopic structure, which consists of an installation end installed on the spray gun displacement mechanism and a free end sleeved on the installation section with a measuring sleeve installed at the bottom; a distance measuring sensor is also fixedly connected to the installation end.

[0011] Preferably, the attitude adjustment mechanism further includes: A motor frame, which is sleeved on the spray gun displacement mechanism and makes an axial linear motion under its drive; A rotating motor, which is fixedly connected to the motor frame. The end of the motor shaft of the rotating motor is fixedly connected with an electric push rod. The extending end of the electric push rod is fixedly connected with a deflection frame. The lower end of the deflection frame is rotatably connected with a deflection arm, and the end of the deflection arm is detachably connected to the spray gun; A deflection motor, which is fixedly connected to the deflection frame and drives the deflection arm to rotate.

[0012] Preferably, the profiling roller is made of tungsten carbide material, and multiple groups of the profiling rollers and the measuring sleeves are arranged at equal intervals under the displacement guide block.

[0016] The beneficial effects of the present invention are as follows: 1.

[0017] 2. The inner cavity of the measuring sleeve is hinged with an amplification lever through a rotating shaft. The limiting slider rotatably connected to the short arm end forms a sliding pair with the sliding groove opened at the top of the contact rod. When the tungsten carbide profiling roller contacts the surface of the workpiece and generates a push to contract the contact rod into the measuring sleeve, at this time, the limiting slider in the sliding groove at the top of the contact rod rotates along the end of the short arm of the amplification lever, converting the linear displacement of the contact rod into the rotational movement of the lever around the rotating shaft. Based on the proportional relationship between the length of the short arm and the long arm of the lever, the displacement sensor fixed on the inner side wall of the sleeve can clearly capture the deformation signal of ±0.05 mm level that cannot be recognized by the traditional structure, achieving the technical effect of accurately obtaining the curvature change gradient of the workpiece surface and further generating the compensation parameter of the pitching angle of the spray gun.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0022] As Figures 1 to 5As shown in the figure, an embodiment of the present invention provides an adjustable intelligent spraying device for new energy vehicle parts, including a spraying chamber 1, and a workpiece placement table 2 is installed at the bottom of the spraying chamber 1; it further includes: A spray gun displacement mechanism 3, the spray gun displacement mechanism 3 is installed in the spraying chamber 1, and the spray gun displacement mechanism 3 is used to move the spray gun 4 to the starting position of spraying of the part to be sprayed; An attitude adjustment mechanism 5, the attitude adjustment mechanism 5 includes the spray gun 4, and the attitude adjustment mechanism 5 is installed on the spray gun displacement mechanism 3 for adjusting the spraying attitude of the spray gun 4; A curved surface detection mechanism 6, the curved surface detection mechanism 6 is installed on the spray gun displacement mechanism 3 together with the attitude adjustment mechanism 5, and the curved surface detection mechanism is used to detect the curvature change of the workpiece surface before the spray gun 4 sprays, and transmit the detection result to the attitude adjustment mechanism 5.

[0023] As an embodiment of the present invention, the spray gun displacement mechanism 3 includes: A main drive motor 7, the main drive motor 7 is fixedly connected to the outer side wall of the spraying chamber 1, and the drive shaft of the main drive motor 7 extends into the spraying chamber 1; An angle plate 8, one end of the angle plate 8 is fixedly connected to the part of the drive shaft of the main drive motor 7 located in the spraying chamber 1; A ball screw 9, the ball screw 9 passes through the other end of the angle plate 8 and is connected to a drive assembly fixedly connected to the angle plate 8; A guide rod 10, the guide rod 10 is fixedly connected to the angle plate 8 and is arranged equidistantly from the ball screw 9.

[0024] As an embodiment of the present invention, the curved surface detection mechanism 6 includes: A profiling roller 11, the profiling roller 11 is rotatably connected to the end of a contact rod 12; A measuring sleeve 13, the contact rod 12 is sleeved in the measuring sleeve 13, and the top end of the contact rod 12 is elastically connected to the end of the measuring sleeve 13 through a return spring 14; A displacement guide block 15, the displacement guide block 15 is sleeved on the spray gun displacement mechanism 3 and makes an axial linear motion under its drive, and the top end of the measuring sleeve 13 is fixedly connected to the bottom of the displacement guide block 15; A displacement sensor 16, the displacement sensor 16 is fixedly connected inside the measuring sleeve 13 for real-time obtaining of the displacement change of the contact rod 12 during operation.

[0025] As an embodiment of the present invention, the profiling roller 11 is made of tungsten carbide, and multiple groups of the profiling roller 11 and the measuring sleeve 13 are arranged equidistantly under the displacement guide block 15.

[0026] During operation, first ensure that the workpiece to be processed is carried and fixed on the workpiece placement table 2 at the bottom of the spraying chamber 1. Then, the main drive motor 7 of the spray gun displacement mechanism 3 is started. Its drive shaft penetrates the side wall of the spraying chamber 1 and is fixedly connected to the proximal end of the angle plate 8 through a flange, driving the angle plate 8 to rotate at a set angle around the motor shaft of the main drive motor 7 under the action of the plc control center. The ball screw 9 and the guide rod 10 are arranged in parallel at the distal end of the angle plate 8. When the angle plate 8 rotates to the preset starting angle and the spraying operation of new energy vehicle parts is carried out, the drive assembly drives the ball screw 9 to rotate, thereby driving the attitude adjustment mechanism 5 and the curved surface detection mechanism 6 sleeved thereon to perform linear reciprocating motion along the axis of the ball screw 9, and completing the spraying work during the reciprocating motion. Among them, the displacement guide block 15 of the curved surface detection mechanism 6 moves axially, synchronously driving the array of measurement sleeves 13 fixed to the bottom of the guide block. The tungsten carbide profiling roller 11 of the curved surface detection mechanism 6 is elastically connected to the reset spring 14 between the measurement sleeves 13 through the contact rod 12. When the profiling roller 11 contacts the workpiece surface during the movement of the displacement guide block 15, the change in the surface curvature of the workpiece forces the contact rod 12 to compress the spring to generate a telescopic displacement. The built-in displacement sensor 16 captures the displacement amount in real time and converts it into an electrical signal. After receiving the signal, the angle adjustment mechanism drives the spray gun 4 to deflect by a corresponding angle. During this process, multiple groups of tungsten carbide profiling rollers 11 contact the workpiece surface in an array form to form a distributed pressure induction. When there are protrusions or depressions on the workpiece surface, the contact rod 12 is squeezed by the curved surface to generate different compression amounts. The displacement sensor 16 connected to its top will detect the axial displacement data of the contact rod 12 in the measurement sleeve 13 in real time and transmit it to the PLC control system through a signal line. At this time, the PLC converts the displacement change amount of each measurement point into a curvature change gradient model according to the preset algorithm, and synchronously calculates the ideal spraying parameters of the spray gun 4 relative to the current detection area, including the vertical distance compensation value between the nozzle of the spray gun 4 and the workpiece surface, the pitch angle correction amount, and the lateral offset compensation coefficient, so that the spray gun 4 has established a motion trajectory and spraying angle that perfectly match the surface characteristics of the target area before formal spraying, enabling the paint particles to cover the workpiece surface along the optimal path under the action of electric field adsorption, effectively eliminating defects such as coating edge splashing and corner accumulation caused by lag adjustment of traditional equipment, improving the uniformity of the coating thickness on the workpiece surface, and reducing the rework rate of automotive parts. The high wear-resistant characteristics of tungsten carbide material ensure the dimensional stability of the profiling roller 11 during long-term contact detection.

[0027] As an implementation manner of the present invention, a magnification lever 17 is rotatably connected in the inner cavity of the measurement sleeve 13. The short arm of the magnification lever 17 is in contact and cooperation with the top end of the contact rod 12 extending into the measurement sleeve 13. The displacement sensor 16 is located on the inner side wall of the measurement sleeve 13 to measure the horizontal displacement of the end of the long arm of the magnification lever 17.

[0028] As an implementation manner of the present invention, a sliding groove 26 is provided at the top end of the contact rod 12, and a limiting slider 27 is rotatably connected to the end of the short arm of the amplification lever 17. The limiting slider 27 is slidably connected in the sliding groove 26.

[0029] As an implementation manner of the present invention, the displacement guide block 15 is an electric telescopic structure, which is composed of a mounting end 18 installed on the spray gun displacement mechanism 3 and a free end 19 sleeved on the mounting section and having a measuring sleeve 13 installed at the bottom; a distance measuring sensor 20 is also fixedly connected to the mounting end 18.

[0030] During operation, the distance measuring sensor 20 on the mounting end 18 of the displacement guide block 15 gives the approximate distance between it and the workpiece surface. Then, the free end 19 of the displacement guide block 15 extends and moves downward to move the measuring sleeve 13 to a position close to the workpiece surface, so as to ensure that during the curved surface detection process, when the profiling roller 11 detects the surface curvature, it can always be within the elastic expansion range between the measuring sleeve 13 and the contact rod 12; an amplification lever 17 is hinged in the inner cavity of the measuring sleeve 13 through a rotating shaft, and a limiting slider 27 rotatably connected to the short arm end thereof forms a sliding pair with the sliding groove 26 provided at the top end of the contact rod 12; when the tungsten carbide profiling roller 11 contacts the workpiece surface and pushes the contact rod 12 to contract into the measuring sleeve 13, at this time, the limiting slider 27 in the sliding groove 26 at the top end of the contact rod 12 rotates along the end of the short arm of the amplification lever 17, converting the linear displacement of the contact rod 12 into the rotational motion of the lever around the rotating shaft; based on the proportional relationship between the length of the short arm and the length of the long arm of the lever, the displacement sensor 16 fixed to the inner side wall of the sleeve can clearly capture the deformation signal of ±0.05 mm level that cannot be recognized by the traditional structure. The PLC control system synchronously receives the displacement data of the long arm of the amplification lever 17 and the real-time height information of the displacement guide block 15 fed back by the distance measuring sensor 20, and realizes the technical effect of accurately obtaining the curvature change gradient of the workpiece surface and then generating the pitch angle compensation parameter of the spray gun 4 by establishing a mapping model of the compression amount of the contact rod 12 and the lever amplification coefficient.

[0031] As an implementation manner of the present invention, the attitude adjustment mechanism 5 further includes: A motor frame 21, which is sleeved on the spray gun displacement mechanism 3 and moves axially linearly under its drive; A rotating motor 22, which is fixedly connected to the motor frame 21. The end of the motor shaft of the rotating motor 22 is fixedly connected with an electric push rod 23. The extending end of the electric push rod 23 is fixedly connected with a deflection frame 24. The lower end of the deflection frame 24 is rotatably connected with a deflection arm 25. The end of the deflection arm 25 is detachably connected to the spray gun 4; A deflection motor, which is fixedly connected to the deflection frame 24 and drives the deflection arm 25 to rotate.

[0032] During operation, after the attitude adjustment mechanism 5 receives the adjustment signal from the plc control system, the electric push rod 23 first extends to an appropriate position, and then the deflection motor on the deflection frame 24 starts. The deflection arm 25 rotates around the center point of the ball hinge for pitching motion, so that the axis of the spray gun 4 is preliminarily aligned with the normal direction of the curved surface. When dealing with a convex curved surface, the electric push rod 23 contracts to lift the spray gun 4, and the deflection motor synchronously drives the spray gun 4 to lean backward to avoid paint accumulation. When dealing with a concave area, the electric push rod 23 extends and cooperates with the forward tilt of the deflection arm 25 to ensure that the spray gun 4 reaches the bottom of the groove. During the spraying process, if the curvature of the curved surface changes greatly, such as when encountering a deep concave surface and it is difficult to achieve a good spraying effect with conventional deflection movement, the spray gun 4 can be inserted into the concave surface. After adjusting the deflection angle, the rotation motor 22 is started, and surface spraying is carried out by means of constant-speed circumferential rotation, so as to ensure the uniformity of the coating thickness and reduce the rework rate of new energy vehicle parts.

[0033] As an implementation manner of the present invention, the surface of the component placing table 2 is provided with positioning and mounting holes 28 for adapting to clamping fixtures of different specifications.

[0034] As an implementation manner of the present invention, the chamber door 29 of the spraying chamber 1 is a sliding door embedded in the side wall of the spraying chamber 1 and slidably and sealingly connected to the side wall of the spraying chamber 1, and a viewing window 30 is opened on the sliding door.

[0035] During operation, among the new energy vehicle parts to be sprayed, in addition to the parts directly placed on the component placing table 2, there are also some parts that need to be suspended in the air through other clamping fixtures for spraying. Therefore, the positioning and mounting holes 28 arranged in an equidistant matrix on the surface of the component placing table 2 have a hole depth more than 1.2 times the length of the positioning pin of the fixture. When processing these workpieces, the positioning pins at the bottom of the corresponding clamping fixture can form an interference fit with the mounting holes, and the four-corner hydraulic locking mechanism is used to apply a gradient pressing force, so that the displacement of the workpiece during the spraying process is stabilized within a very small range. On the other hand, the sliding door embedded in the side wall of the spraying chamber 1 adopts a double-layer tempered glass and aluminum alloy composite frame, and the depth of its guiding chute is designed to be 1.5 times the thickness of the door body. When closed, the fluororubber sealing strip wrapped around the outer frame of the chamber door 29 forms an airtight contact with the inner wall of the spraying chamber 1, effectively blocking the diffusion of paint mist and the intrusion of external dust. The viewing window 30 on the sliding door can not only be used as a visual window for the staff, but also be equipped with an image processing system to monitor the spraying situation of the workpieces in the spraying chamber 1 in real time. When an abnormal situation is detected, an alarm is triggered, thus providing a highly adaptable solution for the precision spraying of new energy vehicle parts. The image processing system and alarm system mentioned here are all prior arts, so they will not be elaborated.

[0036] The basic principles, main features and remarkable advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above specific embodiments. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements to adapt to different usage environments and customer requirements, and these changes and improvements all fall within the protection scope of the present invention. The protection scope claimed by the present invention is defined by the appended claims and their equivalents.
