Detailed Implementation

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] To better understand the technical solutions of this disclosure, the paint leveling equipment and paint dispensing device of this disclosure will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations can be combined with each other.

[0026] Figure 1 The diagram shown is a plan view of a paint application device 10 according to an exemplary embodiment of the present disclosure. Figure 2 Figure 2 The diagram shown is a structural schematic of a paint dispensing device 10 according to an exemplary embodiment of this disclosure. See also... Figure 1 and Figure 2 As shown, this disclosure provides a paint leveling device 11, which includes a roller 12 and a drive assembly 13.

[0027] The outer wall of the roller 12 is provided with multiple mounting positions 14 for fixing the curved workpiece 15. The mounting position 14 refers to the area on the outer wall of the roller 12 used to fix the curved workpiece 15. In one embodiment, the mounting position 14 has a groove to accommodate the curved workpiece 15, thus facilitating the determination of the position of the curved workpiece 15. In another embodiment, the paint leveling device 11 further includes a snap-fit ​​assembly disposed on the mounting position 14 on the outer wall of the roller 12 for snap-fitting and fixing the curved workpiece 15, thus facilitating the installation and removal of the curved workpiece 15. In this embodiment, the mounting position 14 is provided with adhesive for bonding and fixing the curved workpiece 15. This allows the curved workpiece 15 to be fixed to the outer wall of the roller 12 by adhesive, resulting in a simple and secure fixation method.

[0028] The drive assembly 13 is connected to one end of the roller 12 arranged along its axial direction and is used to drive the roller 12 to rotate. The drive assembly 13 can be used to drive the roller 12 to swing back and forth, or to drive the roller 12 to rotate. In this embodiment, the drive assembly 13 is used to drive the roller 12 to rotate at a set speed, so that the roller 12 can rotate at a uniform speed, making the paint distribution on the surface of the curved workpiece 15 more uniform.

[0029] In one embodiment, the drive assembly 13 is used to drive the roller 12 to rotate for a set duration, the set duration being greater than the leveling length of the paint on the surface of the curved workpiece 15. In this embodiment, the set duration is greater than 3 minutes.

[0030] The paint leveling device 11 disclosed herein includes a roller 12 and a drive assembly 13. The outer wall of the roller 12 has multiple mounting positions 14 for fixing curved workpieces 15. The drive assembly 13 is connected to one end of the roller 12 arranged along its axial direction and drives the roller 12 to rotate. This eliminates the height difference of the curved workpiece 15, allowing the paint on the surface of the curved workpiece 15 to gradually and evenly distribute during the rotation of the roller 12. The paint layer formed on the curved workpiece 15 has a consistent thickness, improving the uniformity and quality of the paint layer formed on the curved workpiece 15. The drive assembly 13 drives the roller 12 to rotate, and the curved workpiece 15 can change position as the roller 12 rotates, so that any position of the curved workpiece 15 may be at the highest point of the paint leveling device 11, thereby reducing or eliminating the uneven leveling phenomenon caused by gravity and surface tension.

[0031] In one embodiment, the curvature of the outer wall of the roller 12 is equal to the curvature of the curved workpiece 15. This allows the paint on the surface of the curved workpiece 15 to be distributed more evenly during the rotation of the roller 12.

[0032] In one embodiment, a plurality of mounting positions 14 are arranged at intervals along the axial direction of the roller 12 to form mounting rows 16. The number of mounting rows 16 is at least one row. In this way, more curved workpieces 15 can be provided on the outer wall of the roller 12, resulting in higher working efficiency.

[0033] In this embodiment, the number of mounting positions 16 is at least three rows, and the at least three rows of mounting positions 16 are arranged at intervals along the circumference of the roller 12.

[0034] In one embodiment, the drive assembly 13 includes a transmission rod 17 and a drive motor 18, wherein the drive motor 18 can be a stepper motor. One end of the transmission rod 17 is connected to the drive motor 18, and the other end is connected to one end of the roller 12 arranged along its axial direction. This allows for precise control of the roller 12's rotation parameters, such as rotation angle, rotation speed, and rotation duration, by controlling the drive motor 18 according to the curvature of the curved workpiece 15 and the characteristics of the paint used. This, in turn, can more effectively reduce or eliminate unevenness of the paint during natural leveling.

[0035] In one embodiment, the paint leveling device 11 further includes a first control unit 19 for controlling the rotation of the drive motor 18, the first control unit 19 being connected to the drive motor 18. The first control unit 19 can be used to control the drive motor 18 to precisely control relevant parameters of the rotation of the roller 12, such as rotation angle, rotation speed, and rotation duration.

[0036] In one embodiment, the paint leveling device 11 further includes a detection element 20 for detecting the real-time position and speed of the drive motor 18, wherein the detection element 20 can be an encoder. The detection element 20 is connected to a first control unit 19, which can receive the real-time position and speed feedback from the detection element 20 and control the drive motor 18 based on the real-time position and speed. The detection element 20 is located at the output end of the drive motor 18. This makes the paint leveling device 11 more reliable.

[0037] See you again Figure 1 As shown, this disclosure also provides a paint dispensing device 10, which can be applied to the paint dispensing process of curved workpieces 15. The paint dispensing device 10 may include a paint dispensing mechanism 21 and a paint leveling device 11. It should be noted that the description of the paint leveling device 11 in the above embodiments and implementations is also applicable to the paint dispensing device 10 of the embodiments of this disclosure.

[0038] The paint dispensing mechanism 21 can apply paint or other liquid coatings to the surface of the curved workpiece 15. The paint dispensing mechanism 21 includes a paint dispensing head 22, which is located on the top of the roller 12 and is used to apply paint to the curved workpiece 15 fixed in the mounting position 14. In this way, the paint dispensing mechanism 21 can apply paint to the curved workpiece 15 mounted on the roller 12 without the need to transport the curved workpiece 15 after painting, making it more convenient.

[0039] In one embodiment, the paint dispensing mechanism 21 includes a paint storage tank 23, a delivery pipe 24, and a second control unit 25. The delivery pipe 24 connects the paint dispensing head 22 and the paint storage tank 23. The paint dispensing head 22 can be detachably connected to the delivery pipe 24, allowing it to be replaced to suit different curved workpieces 15. The second control unit 25 acquires paint dispensing parameters, including the amount of paint dispensed and the dispensing speed. Based on these parameters, it dispenses paint from the paint storage tank 23 through the paint dispensing head 22. This design offers good adaptability; the second control unit 25 can be flexibly adjusted according to the type of curved workpiece 15 and the paint dispensing requirements, and activates the paint dispensing mechanism 21 to apply paint to the curved workpiece 15, ensuring that the paint is evenly distributed on the surface of the curved workpiece 15. This design provides high versatility and adaptability, thereby improving production efficiency and reducing production costs.

[0040] In one embodiment, the paint dispensing mechanism 21 includes an image sensor 26 connected to a second control unit 25, used to acquire position information of the curved workpiece 15. The second control unit 25 can adjust the position of the paint dispensing head 22 based on the position information of the curved workpiece 15 acquired by the image sensor 26, so that the paint dispensing head 22 can automatically align with the curved workpiece 15 for paint dispensing, making it more convenient and faster. The paint dispensing head 22 can be displaced along three mutually perpendicular directions, which facilitates the adjustment of its position.

[0041] Figure 3 The diagram illustrates a painting method for a curved workpiece 15 according to an exemplary embodiment of this disclosure. See also... Figure 3 As shown, this disclosure also provides a method for applying paint to a curved workpiece 15, including steps S101 to S105.

[0042] In step S101, the arc-shaped workpiece 15 is bonded to the mounting position 14 on the outer side wall of the roller 12.

[0043] In step S102, the second control unit 25 adjusts the position of the paint dispensing head 22 based on the position information of the curved workpiece 15 collected by the image sensor 26. Then, according to the set paint dispensing parameters, the paint in the paint storage tank 23 is discharged from the paint dispensing head 22 to perform a paint dispensing operation on the curved workpiece 15, ensuring that the paint is evenly distributed on the surface of the curved workpiece 15.

[0044] In step S103, after the paint application is completed, the first control unit 19 controls the drive motor 18 to rotate, thereby driving the roller 12 to rotate. The first control unit 19 controls the drive motor 18 to precisely control the relevant parameters of the roller 12's rotation, such as rotation angle, rotation speed, and rotation duration. In this embodiment, the first control unit 19 controls the drive motor 18 to achieve uniform rotation of the roller 12, effectively offsetting the uneven leveling phenomenon caused by gravity and surface tension during the natural leveling process of the paint on the curved workpiece 15.

[0045] In step S104, the curved workpiece 15 is removed from the outer wall of the roller 12 and placed in an environment with a set temperature and humidity for drying and curing. The drying and curing lasts for a preset time so that the paint is fully dried and a uniform and smooth paint layer is formed on the surface of the curved workpiece 15.

[0046] In step S105, the dried and cured curved workpiece 15 is subjected to quality inspection. Indicators such as paint layer thickness, uniformity, and surface quality can be checked, and unqualified curved workpieces 15 are reworked.

[0047] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
