Description

Technical Field

[0001] The present application relates to the field of coating technology, and in particular to a coating device and a wheel hub. Background Art

[0002] With the acceleration of industrialization and increasing consumer demand for personalized products, coating technology is playing an increasingly important role in the manufacturing industry. This is particularly true in the automotive industry, where wheels, as a crucial component of a vehicle, have a direct impact on the overall vehicle's aesthetics and brand image. Traditional wheel coating processes typically rely on a single-color finish. While simple, this process fails to meet market demand for diverse and personalized wheels.

[0003] In the field of wheel hub painting, in order to achieve a two-color or multi-color painting effect, a masking spraying method is usually required. This method involves spraying a layer of color on the wheel hub surface first, then sticking a masking film or masking paper on the part that requires the second color, spraying the second layer of color, and finally removing the masking film or masking paper. The masking spraying process is cumbersome and requires multiple manual operations, resulting in low production efficiency and an inability to meet the needs of large-scale production. The use of masking materials increases production costs, and the process of removing the masking film or masking paper may also cause damage to the painted surface, increasing the scrap rate. Multiple spraying and the use of masking materials not only increase material consumption, but may also generate more industrial waste and pollute the environment. The masking spraying process makes it difficult to achieve complex pattern designs, limiting the diversity and innovation of wheel hub design. Utility Model Content

[0004] In view of this, the purpose of the embodiments of the present application is to provide a coating device to improve the problems of low production efficiency, high cost and pattern restrictions in the prior art.

[0005] The coating equipment includes: a conveying component and a coating component; the conveying component includes: a bottom guide rail, a bottom slider and a bottom plate; the bottom guide rail is arranged in a direction parallel to the supporting surface of the conveying component; the bottom slider is fixed on the bottom guide rail; the bottom plate is connected to the bottom slider; the bottom plate is used to place the parts to be coated; the bottom plate is configured to drive the parts to be coated to move together based on relative stillness with the parts to be coated; the coating component includes: a first coating element and a second coating element; the first coating element and the second coating element are arranged in parallel; the first coating element is used to transfer a first pattern to the parts to be coated; the second coating element is used to transfer a second pattern to the parts to be coated; wherein, the first pattern and the second pattern are different.

[0006] In the above implementation process, the bottom guide rail is arranged parallel to the support surface direction of the conveying assembly, providing stable guidance for the entire conveying process. The bottom slider is fixed to the bottom guide rail to reduce the friction of the bottom plate when it moves on the guide rail, so that the bottom plate can move smoothly along the guide rail. The bottom plate is connected to the bottom slider and is used to place the parts to be painted. The design of the bottom plate allows it to remain relatively stationary with the parts to be painted, so that during the painting process, the parts to be painted will not slide or move on the bottom plate. The movement of the bottom plate is controlled by the power system of the conveying assembly, which can move the parts to be painted from one position to another in the equipment, such as from the loading area to the painting position, and then to the unloading area. The painting assembly includes a first painting element and a second painting element, which are arranged in parallel, so that two different patterns can be painted on the parts to be painted at the same time, thereby improving the painting efficiency. The first painting element is responsible for transferring the first pattern to the parts to be painted. The second painting element is responsible for transferring the second pattern to the parts to be painted.

[0007] The parallel arrangement of the first and second painting elements allows them to work simultaneously, so that the transfer of two patterns can be completed in one painting process, reducing repeated operations and improving production efficiency.

[0008] Optionally, the base plate is configured to move along the bottom guide rail to the edge of the equipment and carry the parts to be painted; when the base plate carries the parts to be painted, the base plate is configured to move the parts to be painted to the painting position; after painting is completed, the base plate is configured to move the parts to be painted to the edge of the equipment.

[0009] In the above implementation, the baseplate typically begins at the edge of the machine, serving as the loading area for parts to be painted. In this area, operators place parts onto the baseplate in preparation for painting. Once the parts are in place, the baseplate moves along the bottom rails. These rails are parallel to the support surface of the conveyor assembly, ensuring the baseplate remains stationary relative to the parts during movement, preventing them from shifting or rotating. Upon reaching the painting station, the first and second painting units begin painting according to pre-programmed procedures. The robotic arms of the painting units dip into ink and transfer the first and second patterns onto the parts supported by the baseplate. After painting is complete, the baseplate moves again along the bottom rails, moving the finished parts from the painting station back to the edge of the machine, where they serve as a discharge area. In this discharge area, operators can conveniently remove the finished wheel hubs and place new parts onto the baseplate, preparing for the next round of painting.

[0010] Optionally, the first coating element includes: a first top guide rail, a first top slider and a first robotic arm; the first top guide rail is arranged in a direction parallel to the supporting surface; the first top slider is fixed on the first top guide rail; the first robotic arm is fixed on the first top slider; the first robotic arm is connected to a first printing head printed with a first pattern.

[0011] In the above implementation, the first top rail is aligned parallel to the support surface, providing a stable movement path for the first robotic arm. A first top slider is secured to the first top rail, supporting and guiding the movement of the first robotic arm, reducing friction and wear and ensuring smooth operation. The first robotic arm is secured to the first top slider and connected to a first print head printed with a first pattern, responsible for transferring the first pattern to the part to be coated.

[0012] Optionally, the second coating element includes: a second top guide rail, a second top slider and a second robotic arm; the second top guide rail is arranged in a direction parallel to the supporting surface, the second coating element is arranged parallel to the first coating element, and is spatially located on both sides of the conveying component; the second top slider is fixed on the second top guide rail; the second robotic arm is fixed on the second top slider; the second robotic arm is connected to a second printing head printed with a second pattern.

[0013] In the above implementation process, the second top guide rail is arranged parallel to the direction of the support surface, providing a stable movement path for the second robot arm. The second top slider is fixed on the second top guide rail to support and guide the movement of the second robot arm, reduce friction and wear, and enable the smooth operation of the robot arm. The second robot arm is fixed on the second top slider, and the second robot arm is connected to a second printing head printed with a second pattern, which is responsible for transferring the second pattern to the part to be coated. The second coating element is arranged parallel to the first coating element, and is spatially located on both sides of the conveying component, so that two patterns can be transferred at the same time, thereby improving the coating efficiency.

[0014] Optionally, the device further includes: an ink cartridge; the ink cartridge contains ink required for painting; and the ink cartridge is arranged on the moving path of the first robotic arm and / or the second robotic arm.

[0015] In the above implementation, the ink cartridge is designed to hold the ink required for the painting process, and its capacity and structure need to meet the requirements of continuous or intermittent painting. The ink cartridge is placed in the movement path of the first and / or second robotic arms, allowing the robotic arms to easily and quickly dip into the ink during the painting process.

[0016] Optionally, the first robotic arm and / or the second robotic arm is configured to move in a direction intersecting with the supporting surface; when the base plate carries the workpiece to be painted to the painting position, the first robotic arm and / or the second robotic arm moves along the guide rail to above the ink cartridge; after moving downward to dip the ink, the robotic arm moves upward along the top guide rail to the painting position.

[0017] In the above implementation process, the first robotic arm and / or the second robotic arm are configured to be able to move in a direction intersecting with the supporting surface, that is, they can move in a plane perpendicular to the moving direction of the base plate, so that the robotic arm can dip ink from the ink cartridge and then move to the painting position to transfer the pattern. When the base plate carrying the part to be painted arrives at the painting position, the first robotic arm and / or the second robotic arm will move along its corresponding top guide rail to above the ink cartridge. After reaching above the ink cartridge, the robotic arm will move downward (the robotic arm is retractable, and here it extends downward) so that its corresponding printing head (the first printing head and / or the second printing head) contacts the ink cartridge and dips in ink. After dipping in ink, the robotic arm will retract upward and move along the top guide rail to the painting position, ready to transfer the ink to the part to be painted.

[0019] In the above implementation process, after the first robotic arm and / or the second robotic arm dips in ink, they will move to the coating position and then move downward so that their printing heads contact the surface of the part to be coated, preparing for pattern transfer. After the robotic arm contacts the part to be coated, it will maintain contact for a period of time, which is called the "first period". During this period, the ink is transferred from the printing head to the surface of the part to be coated to form a pattern. After the first period, the first robotic arm and / or the second robotic arm will move upward and away from the part to be coated, completing a pattern transfer process. After the robotic arm moves away from the part to be coated, the base plate will rotate a certain angle. After the base plate rotates the first angle, the first robotic arm and / or the second robotic arm will move downward again and contact the part to be coated for the next pattern transfer. This step is repeated until all pattern transfers are completed.

[0020] Optionally, the painting equipment further includes: a frame; the painting assembly is fixed on the inner side of the top of the frame; a door panel is installed on the side of the frame; the door panel includes a transparent observation window or an observation window made of a transparent material to display the internal components of the equipment.

[0021] In the above implementation, the coating assembly, including the first coating element and the second coating element, is secured to the top inner side of the frame. Door panels are mounted on the sides of the frame. These doors may be hinged to facilitate opening and closing by an operator to access the interior of the equipment for maintenance or observation.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0032] The present application embodiment provides a coating device, see Figure 1 , Figure 1 A simple schematic diagram of the coating equipment provided in an embodiment of the present application.

[0033] The coating equipment includes: a conveying component 100 and a coating component 200; the conveying component 100 includes: a bottom guide rail 110, a bottom slider 120 and a bottom plate 130; the bottom guide rail 110 is arranged in a direction parallel to the support surface of the conveying component 100; the bottom slider 120 is fixed on the bottom guide rail 110; the bottom plate 130 is connected to the bottom slider 120; the bottom plate 130 is used to place the parts to be coated; the bottom plate 130 is configured to drive the parts to be coated to move together based on relative stillness with the parts to be coated; the coating component 200 includes: a first coating element 210 and a second coating element 220; the first coating element 210 and the second coating element 220 are arranged in parallel; the first coating element 210 is used to transfer a first pattern to the parts to be coated; the second coating element 220 is used to transfer a second pattern to the parts to be coated; wherein the first pattern and the second pattern are different.

[0034] In the above implementation process, the bottom guide rail 110 is arranged parallel to the support surface direction of the conveying assembly 100, providing stable guidance for the entire conveying process. The bottom slider 120 is fixed on the bottom guide rail 110 to reduce the friction of the bottom plate 130 when it moves on the guide rail, so that the bottom plate 130 can move smoothly along the guide rail. The bottom plate 130 is connected to the bottom slider 120 and is used to place the parts to be painted. The design of the bottom plate 130 allows it to remain relatively stationary with the parts to be painted, so that during the painting process, the parts to be painted will not slide or move on the bottom plate 130. The movement of the bottom plate 130 is controlled by the power system of the conveying assembly 100, which can move the parts to be painted from one position to another in the equipment, such as from the loading area to the painting position, and then to the unloading area.

[0035] Optionally, the base plate 130 is configured to move along the bottom rail 110 to the edge of the machine and carry the parts to be painted. When the base plate 130 carries the parts to be painted, the base plate 130 is configured to move the parts to the painting position. After painting is completed, the base plate 130 is configured to move the parts to the edge of the machine. The movement of the base plate 130 can be achieved by an electric, pneumatic, or other power system, which controls the movement speed and position of the base plate 130 according to a preset program.

[0036] Optionally, during the coating process, the base plate 130 moves the part to be coated to the coating position, and the robotic arms of the first and second coating elements 220 move to the ink cartridge (not shown) according to a preset program to dip in ink. After dipping in ink, the robotic arms (first robotic arm 213 and / or second robotic arm 223) move to the coating position, contact the part to be coated, and transfer the pattern to the hub surface. After the transfer is complete, the robotic arms move away, and the base plate 130 rotates a certain angle to prepare for the transfer of the next pattern. This process is repeated until all patterns are transferred.

[0037] In one embodiment of the present application, the entire coating process is coordinated by a control system, including the movement of the base plate 130, the ink dipping and transfer by the robotic arms (first robotic arm 213 and / or second robotic arm 223), and the rotation of the base plate 130. The control system may include programmed logic and sensors to enable the positioning and synchronization of the robotic arms and base plate 130. Optionally, the device may be equipped with a display screen as a control panel to control the device coating process.

[0038] In one embodiment of the present application, the initial position of the base plate 130 is usually at the edge of the equipment, which is the loading area for the parts to be painted. In this area, the operator can place the parts to be painted on the base plate 130 and prepare for the painting operation. Once the parts to be painted are in place, the base plate 130 will move along the bottom guide rail 110. The bottom guide rail 110 is parallel to the support surface of the conveying assembly 100. The base plate 130 always remains relatively stationary with the parts to be painted during the movement, so that the parts to be painted will not be displaced or rotated during the movement. After arriving at the painting position, the first painting element 210 and the second painting element 220 will start the painting operation according to the preset program. The robotic arm of the painting element will dip into the ink and transfer the first pattern and the second pattern on the parts to be painted carried by the base plate 130. After the painting is completed, the base plate 130 will move along the bottom guide rail 110 again, moving the painted parts to be painted from the painting position back to the edge of the equipment. This position can be used as an unloading area for the parts to be painted. In the unloading area, the operator can easily remove the painted wheel hub and place the new parts to be painted on the bottom plate 130 to prepare for the next round of painting operations.

[0039] Specifically, see Figure 2 , Figure 2 A schematic diagram of the coating equipment provided in an embodiment of the present application.

[0040] Optionally, the first coating element 210 includes: a first top guide rail 211, a first top slider 212 and a first robotic arm 213; the first top guide rail 211 is arranged in a direction parallel to the support surface; the first top slider 212 is fixed on the first top guide rail 211; the first robotic arm 213 is fixed on the first top slider 212; the first robotic arm 213 is connected to a first printing head 214 printed with a first pattern.

[0041] In the above implementation, the first top rail 211 is aligned parallel to the support surface, providing a stable movement path for the first robotic arm 213. The first top slider 212 is fixed to the first top rail 211, supporting and guiding the movement of the first robotic arm 213, reducing friction and wear, and ensuring smooth operation of the robotic arm. The first robotic arm 213 is fixed to the first top slider 212 and is connected to a first print head 214 printed with a first pattern, which is responsible for transferring the first pattern to the part to be coated.

[0042] In one embodiment of the present application, during the painting process, the first robotic arm 213 moves along the first top rail 211 according to a preset program to the ink cartridge (not shown), dips into the ink, and then moves to the painting position, where it contacts the part to be painted and transfers the first pattern onto the hub surface. While the first robotic arm 213 is transferring the pattern, the base plate 130 rotates a certain angle based on the painting progress, allowing the robotic arm to transfer the next pattern or proceed to the next painting step.

[0043] Optionally, the second coating element 220 includes: a second top guide rail 221, a second top slider 222 and a second robotic arm 223; the second top guide rail 221 is arranged in a direction parallel to the support surface, and the second coating element 220 is arranged parallel to the first coating element 210, and is spatially located on both sides of the conveying component 100; the second top slider 222 is fixed on the second top guide rail 221; the second robotic arm 223 is fixed on the second top slider 222; the second robotic arm 223 is connected to the second printing head 224 printed with a second pattern.

[0044] In the above implementation process, the second top guide rail 221 is arranged parallel to the direction of the support surface, providing a stable movement path for the second robotic arm 223. The second top slider 222 is fixed on the second top guide rail 221, supporting and guiding the movement of the second robotic arm 223, reducing friction and wear, and ensuring the smooth operation of the robotic arm. The second robotic arm 223 is fixed on the second top slider 222, and the second robotic arm 223 is connected to a second printing head 224 printed with a second pattern, which is responsible for transferring the second pattern to the part to be coated. The second coating element 220 is arranged parallel to the first coating element 210, and is spatially located on both sides of the conveying assembly 100, so that two patterns can be transferred at the same time, thereby improving the coating efficiency.

[0045] Optionally, the device further includes: an ink cartridge (not shown); the ink cartridge (not shown) contains ink required for painting; the ink cartridge (not shown) is arranged on the moving path of the first robotic arm 213 and / or the second robotic arm 223.

[0046] In the above implementation, the ink cartridge (not shown) is designed to hold the ink required for the painting process. Its capacity and structure must meet the requirements of continuous or intermittent painting. The ink cartridge (not shown) is placed in the movement path of the first robotic arm 213 and / or the second robotic arm 223, allowing the robotic arm to easily and quickly dip into the ink during the painting process.

[0047] Optionally, the location of the ink cartridge (not shown) is designed to allow the robot arm to easily reach it without interfering with the operation of other components, such as the transport assembly 100 and the coating element. The design of the ink cartridge (not shown) may include an easily accessible opening or channel so that the print head of the robot arm can smoothly dip into the ink. The ink cartridge (not shown) is designed to be easy to maintain and replace so that the operator can quickly operate when the ink runs out or the ink color needs to be changed. The print head of the robot arm is designed to be able to dock with the opening or channel of the ink cartridge (not shown) to enable efficient transfer of ink.

[0048] Optionally, the first robotic arm 213 and / or the second robotic arm 223 are configured to move in a direction intersecting the supporting surface; when the base plate 130 carries the workpiece to be painted to the painting position, the first robotic arm 213 and / or the second robotic arm 223 moves along the guide rail to above the ink cartridge (not shown); after moving downward to dip in ink, the robotic arm moves upward along the top guide rail to the painting position.

[0049] In the above implementation process, the first robotic arm 213 and / or the second robotic arm 223 are configured to be able to move in a direction intersecting with the support surface, that is, they can move in a plane perpendicular to the moving direction of the base plate 130, so that the robotic arm can dip ink from the ink cartridge (not shown) and then move to the coating position for pattern transfer. When the base plate 130 carries the part to be coated and arrives at the coating position, the first robotic arm 213 and / or the second robotic arm 223 will move along its corresponding top guide rail to above the ink cartridge (not shown). After arriving above the ink cartridge (not shown), the robotic arm will move downward (the robotic arm is retractable, and here it extends downward) so that its corresponding print head (the first print head 214 and / or the second print head 224) contacts the ink cartridge (not shown) and dips in ink. After dipping in ink, the robotic arm will retract upward and move along the top guide rail to the coating position, ready to transfer the ink to the part to be coated.

[0050] Optionally, the first robotic arm 213 and / or the second robotic arm 223 are configured to move downward and contact the workpiece to be coated when the first robotic arm 213 and / or the second robotic arm 223 dips ink and reaches the coating position; the first robotic arm 213 and / or the second robotic arm 223 are also configured to move downward and contact the workpiece to be coated after a first period of time has passed since the first robotic arm 213 and / or the second robotic arm 223 moved away from the workpiece to be coated; the base plate 130 is configured to rotate a first angle when the first robotic arm 213 and / or the second robotic arm 223 is away from the workpiece to be coated; the first robotic arm 213 and / or the second robotic arm 223 are configured to move downward again and contact the workpiece to be coated after the base plate 130 rotates the first angle; and this process is repeated until all pattern transfers to the workpiece to be coated are completed.

[0051] In the above implementation process, after the first robotic arm 213 and / or the second robotic arm 223 dips in ink, they will move to the coating position and then move downward so that their print heads contact the surface of the part to be coated, preparing for pattern transfer. After the robotic arm contacts the part to be coated, it will maintain contact for a period of time, which is called the "first period". During this period, the ink is transferred from the print head to the surface of the part to be coated to form a pattern. After the first period, the first robotic arm 213 and / or the second robotic arm 223 will move upward and away from the part to be coated, completing a pattern transfer process. After the robotic arm moves away from the part to be coated, the base plate 130 will rotate a certain angle, which is called the "first angle". The setting of the first angle depends on the number and layout of the patterns to be transferred on the part to be coated, as well as the coverage of the robotic arm. The rotation of the base plate 130 needs to be precisely controlled so that the print head can be aligned when the pattern is transferred next time. After the bottom plate 130 rotates to the first angle, the first robotic arm 213 and / or the second robotic arm 223 will move downward again to contact the workpiece to be coated for the next pattern transfer. This step is repeated until all pattern transfers are completed.

[0052] Optionally, the painting equipment also includes: a frame (not shown); a painting assembly 200 is fixed on the inner side of the top of the frame (not shown); a door panel is installed on the side of the frame (not shown); the door panel includes a transparent or transparent material-based observation window to display the components inside the equipment.

[0053] In the above implementation process, the coating assembly 200, including the first coating element 210 and the second coating element 220, is fixed to the top inner side of the frame (not shown). A door panel is installed on the side of the frame (not shown), and the door panel can be hinged to facilitate the operator to open and close to access the interior of the equipment for maintenance or observation. The door panel includes an observation window that is transparent or based on a transparent material, so that the operator can observe the coating process and component status inside the equipment without opening the door panel.

[0054] Optionally, the part to be coated is a wheel hub.

[0055] For example, see Figure 3 , Figure 3 A schematic diagram of a robotic arm provided in an embodiment of the present application. The first robotic arm 213 and / or the second robotic arm 223 can both be Figure 4 The structure of the robotic arm is shown.

[0056] Among them, such as Figure 3The shown robotic arm connection part 201 is connected to the top slider (the first top slider 212 and / or the second top slider 222), the robotic arm telescopic part 202 is used for the up and down movement of the robotic arm (the first robotic arm 213 and / or the second robotic arm 223) when dipping ink or transferring patterns, and the print head connection part 203 is used to connect or replace the print head (the first print head 214 and / or the second print head 224).

[0057] See also Figure 4 , Figure 4 A wheel hub is provided in an embodiment of the present application. The wheel hub includes a wheel hub surface, wherein the wheel hub surface includes a first pattern and a second pattern, and the first pattern and the second pattern are painted using a painting device.

[0058] In the above implementation process, before the coating process begins, the surface of the hub needs to be cleaned and pretreated so that the surface is clean, grease-free, and has good coating adhesion. The design of the first pattern and the second pattern needs to match the printing head of the coating equipment so that the pattern can be transferred to the surface of the hub. The hub is placed on the base plate 130 of the coating equipment and then moved to the coating position through the conveying assembly 100. At the coating position, the first robotic arm 213 and / or the second robotic arm 223 dips in ink according to a preset program and transfers the first pattern and the second pattern to the surface of the hub. After the coating is completed, the hub is transferred to a special drying equipment for the drying and curing process of the hub.
