Description

Technical Field

[0001] This utility model relates to the field of spraying equipment, and in particular to a spraying equipment for automotive parts. Background Technology

[0002] PVC spraying is a surface treatment technology that uses specialized equipment to uniformly spray polyvinyl chloride (PVC)-based coatings onto the surface of a target object in a mist form, forming a protective or decorative coating. PVC, as a thermoplastic, has advantages such as corrosion resistance, good weather resistance, and low cost. It is widely used in automotive parts manufacturing for surface treatment of interior parts (such as dashboards and seat surfaces), exterior parts (such as bumpers and trim strips), and wire insulation.

[0003] In automotive parts manufacturing, automotive parts painting equipment typically includes high-pressure spray guns, a painting system, and a drying oven. Its working principle involves pumping liquid PVC coating to the spray gun via a high-pressure pump, atomizing it, and then uniformly spraying it onto the surface of the parts. Automated painting lines use robotic arms or conveyor belts to transport parts for painting. After painting, the parts enter the drying oven, where they are heated and cured to form a tough PVC coating.

[0004] However, when using conveyor belts for conveying and spraying in automotive parts painting equipment proposed by related technologies, some paint is sprayed onto the conveyor belt outside the product coverage area and adheres to the conveyor belt, resulting in paint waste. Therefore, there is an urgent need for automotive parts painting equipment with high paint utilization rate. Utility Model Content

[0022] Reference Figure 1 and Figure 2 This application provides an automotive parts painting equipment applicable to PVC painting of automotive parts. In automotive parts manufacturing, polyvinyl chloride (PVC) is commonly used for surface treatment of interior parts (such as dashboards and seat surfaces) and exterior parts (such as bumpers and trim strips) due to its excellent corrosion resistance, weather resistance, and cost-effectiveness. However, traditional painting processes result in paint waste and environmental pollution, necessitating equipment for efficient paint recycling to improve production efficiency and environmental performance. This application, through innovative design, provides a solution integrating efficient painting and waste recycling to meet the specific needs of automotive parts. Specifically, in a preferred embodiment, the automotive parts painting equipment of this application includes: Rack 1; Conveyor belt 2, located on frame 1, is used to transport products to be sprayed; The spray head 3 is mounted on the frame 1 and spans the upper side of the conveyor belt 2. The spray head 3 is used to perform spraying operations on the product to be sprayed. The scraping and collecting mechanism 4 includes a first scraper 41 and a collecting component 42. The first scraper 41 is mounted on the frame 1, and one end of the first scraper 41 can abut against the conveyor belt 2. The collecting component 42 is mounted on the other end of the first scraper 41 and is used to collect the paint.

[0023] In this embodiment, the automotive parts painting equipment integrates conveying, painting, and waste recycling functions to achieve efficient and environmentally friendly production for the PVC painting needs of automotive parts. Its core principle is as follows: The conveyor belt 2 transports the parts to be coated, ensuring a continuous and efficient production process. The spray head 3 is positioned above the conveyor belt 2 and uses controlled spraying technology to evenly apply PVC coating, meeting the corrosion resistance and weather resistance requirements of the parts. The scraping and collecting mechanism 4 uses a first scraper 41 to scrape away any coating not adhering to the product on the belt, which is then collected and stored by the collecting component 42 for recycling, preventing waste and environmental pollution.

[0024] The working process of the automotive parts painting equipment described in this application can be briefly described as follows: Automotive parts to be painted (such as interior parts: dashboard, seat surfaces; exterior parts: bumpers, trim strips) are placed on conveyor belt line 2.

[0025] The conveyor belt 2 is supported by the frame 1 and transports parts to the spraying area at a stable speed to ensure continuous production.

[0026] When the parts arrive at the spraying area, the spray head 3, which is mounted on the frame 1 and spans the conveyor belt 2, starts to spray PVC coating.

[0027] The spray head 3 adjusts the spraying parameters (such as spray angle and paint amount) according to the shape and size of the parts to ensure uniform coating and meet surface quality requirements.

[0028] During the spraying process, because some parts require large-area spraying, some paint may not adhere to the parts and may drip or remain on the conveyor belt 2. One end of the first scraper 41 is pressed against the surface of the conveyor belt 2 to scrape off the residual paint. The scraped paint is collected and recycled along the first scraper 41 by a collection component 42 located at the other end of the first scraper 41, facilitating subsequent processing or recycling. For example, the collection component 42 can be a device with active recycling capability, such as a negative pressure suction device, or it can be a container without active recycling capability, such as a storage box or storage bin.

[0029] This application achieves the following beneficial effects by setting the above structure: The coordinated operation of the conveyor belt 2 and the spray head 3 enables automated spraying, significantly improving production efficiency and meeting the needs of large-scale automotive parts manufacturing. Precise spraying reduces paint usage, lowers production costs, and ensures that the coating quality meets corrosion resistance and weather resistance requirements. The scraper collection mechanism 4 effectively recovers spilled or unadhered paint, reducing raw material waste and minimizing environmental pollution caused by paint volatilization or indiscriminate discharge. The storage design of the collection component 42 facilitates waste management, reduces waste, and promotes sustainable development.

[0030] Reference Figure 1 and Figure 2 In some embodiments, the conveyor belt 2 proposed in this application includes: At least two rollers 21 are spaced apart, and each roller 21 is rotatably mounted on the frame; An annular belt 22 is fitted onto at least two rollers 21. The annular belt 22 is used to carry the product to be sprayed. A drive motor 23 is mounted on the frame 1, and the output end of the drive motor 23 is connected to any roller 21.

[0031] In this embodiment, the drive motor 23 serves as a power source and is connected to any roller 21 through its output end (e.g., via gear, chain, or belt drive) to provide rotational power.

[0032] The motor drives the roller 21 to rotate, and the rotation of the roller 21 causes the annular belt 22 sleeved on it to circulate along a fixed path.

[0033] An annular belt 22 is fitted over at least two rollers 21 to form a closed loop. The spacing of the rollers 21 ensures belt tension and stable operation. The cyclical movement of the annular belt 22 smoothly transports the automotive parts to be painted from their starting position to the painting area, and after painting, continues to the next process, for example, unloading painted products.

[0034] Reference Figure 1 and Figure 2 In some embodiments, the first scraper 41 proposed in this application spans the conveying direction of the conveyor belt 2 and is inclined; the annular belt 22 includes an upper conveying section and a lower return section, the upper conveying section is located below the spray head 3, the first scraper 41 is located below the lower conveying section, and the collecting assembly 42 is disposed on the lower side of the first scraper 41.

[0035] In this embodiment, the annular belt 22 forms a closed loop through at least two rollers 21 (driven by a drive motor 23), and is divided into an upper conveying section and a lower return section.

[0036] The upper conveyor section carries the automotive parts to be painted, and the PVC paint is sprayed onto them from below the spray head 3. During the painting process, some paint may not adhere to the parts and may drip or remain on the surface of the belt in the upper conveyor section.

[0037] The lower return section serves as the recirculation return section of the belt, carrying the residual paint to the area below.

[0038] The first scraper 41 spans the conveying direction of the conveyor belt line 2, covers the width of the belt, and ensures full contact with the belt surface of the lower return section.

[0039] The first scraper 41 is set at an angle, with one end close to the outer surface of the belt in the lower return section (i.e., the bearing surface of the belt faces downward in the return section), and removes the paint residue on the belt through physical contact.

[0040] The tilted design allows the scraped paint to flow along the surface of the scraper towards the lower end under the influence of gravity, making it easier to collect.

[0041] The collecting component 42 is located below the first scraper 41 (i.e., at the lower inclined end) and catches the paint that slides off the scraper. The collecting component 42 (which may be a container, tank or other storage device) centrally stores the scraped PVC paint, preventing the paint from scattering or evaporating, keeping the working environment clean, and facilitating subsequent processing or recycling.

[0042] Reference Figure 1 and Figure 2 In some embodiments, the collection component 42 proposed in this application includes a paint conveyor belt 421 disposed below the first scraper 41, a second scraper 422 disposed at the end of the paint conveyor belt 421, and a collection bin 423 disposed below the second scraper 422.

[0043] In this embodiment, the lower return section of the annular belt 22 carries the paint that drips or remains during the spraying process to the lower part, and the first scraper 41 (set at an angle and spanning the conveying direction) is in close contact with the belt surface of the lower return section to scrape off the residual paint.

[0044] Because the first scraper 41 is inclined, the scraped paint slides along the surface of the scraper to the lower end under the action of gravity and falls directly onto the paint conveyor belt 421 below.

[0045] The paint conveyor belt 421 serves as the primary receiving part of the collection assembly 42, used to receive and transport the paint falling from the first scraper 41, maintaining the orderly flow of waste.

[0046] The paint conveyor belt 421 can be an independent belt system that receives paint that slides off the first scraper 41 and transports the paint to the end along its running direction.

[0047] At the end of the paint conveyor belt 421, a second scraper 422 is placed close to the surface of the paint conveyor belt 421 to scrape the paint off the conveyor belt laterally. The design of the second scraper 422 is similar to that of the first scraper 41, and is intended to ensure that residual paint on the paint conveyor belt 421 is thoroughly removed, keeping the belt clean and concentrating the paint towards the next collection point.

[0048] The receiving hopper 423 is located below the second scraper 422 to collect the paint scraped off from the second scraper 422. As the final collection container, the receiving hopper 423 centrally stores the scraped PVC paint, facilitating subsequent processing (such as filtration, recycling, or safe discharge) and ensuring the standardization and efficiency of waste management.

[0049] Reference Figure 1 and Figure 2 In some embodiments, the automotive parts painting equipment proposed in this application further includes a mounting structure 5 disposed on the frame 1 and a locking mechanism disposed on the mounting structure 5. The first scraper 41 is swayably disposed on the mounting structure 5, and the locking mechanism is used to configure the first scraper 41 as follows: The first scraper 41 can swing relative to the mounting structure 5; or The first scraper 41 is fixed relative to the mounting structure 5.

[0050] In this embodiment, the mounting structure 5 is fixed on the frame and located below the return section of the annular belt, providing a stable mounting platform for the first scraper 41.

[0051] The first scraper 41 is pivotally mounted via the mounting structure 5 (possibly via a pivot, hinge, or other rotatable connection), allowing the scraper to swing relative to the mounting structure 5 about a certain axis, adjusting its tilt angle or contact position with the belt.

[0052] The oscillating function enables the first scraper 41 to dynamically adapt to different scraping requirements, such as: Angle adjustment: Change the tilt angle of the scraper to optimize the contact angle with the lower return section of the annular belt and improve scraping efficiency.

[0053] Pressure adjustment: The contact force between the scraper and the belt is adjusted by swinging to adapt to different coating viscosities or belt surface conditions.

[0054] Ease of maintenance: The swing mechanism allows the scraper to be temporarily lifted off the belt surface, making it easy to clean, replace, or inspect.

[0055] The locking mechanism controls the working state of the first scraper 41 and provides two configurations: Swingable state: When the locking mechanism is not fully locked (e.g., bolts are loose or no fixing force is applied), the first scraper 41 can swing freely relative to the mounting structure 5, allowing dynamic adjustment of the angle or position to optimize the scraping effect or facilitate maintenance operations.

[0056] Fixed state: The locking mechanism locks the first scraper 41 at a specific angle or position through a fixing mechanism (such as tightening bolts or other locking devices), ensuring that the scraper remains stable during operation, closely adheres to the belt surface, and continuously and efficiently scrapes away the coating.

[0057] Reference Figure 1 and Figure 2 In some embodiments, the mounting structure 5 proposed in this application includes a mounting base 51 and two adapter plates 52. The two adapter plates 52 are respectively disposed on opposite sides of the annular belt 22 along the conveying direction. The two ends of the mounting base 51 are respectively connected to the two adapter plates 52, and the mounting base 51 is swayably disposed on the adapter plates 52. The mounting base 51 is used to install the first scraper 41.

[0058] In this embodiment, two adapter plates 52 are respectively disposed on opposite sides of the annular belt 22 along the conveying direction (i.e., the left and right sides of the belt width), and fixed to the frame 1 or related support structure, providing a stable mounting base for the mounting seat 51. The symmetrical distribution of the adapter plates 52 ensures that the mounting seat 51 spans the entire belt width, allowing the first scraper 41 to cover the entire surface of the annular belt 22 and completely scrape off any residual coating.

[0059] The mounting base 51 is connected to two adapter plates 52 at both ends to form a stable lateral support structure that directly supports the first scraper 41.

[0060] Mounting base 51 is pivotally mounted on adapter plate 52 (exemplarily, via hinge, bearing or other rotatable connection), allowing dynamic adjustment of the angle or position of first scraper 41.

[0061] The oscillating function allows the first scraper 41 to adjust its tilt angle or contact pressure with the belt as needed, optimizing the scraping effect. For example: Angle adjustment: Ensure the scraper maintains the optimal contact angle with the belt surface to enhance scraping efficiency and reduce paint residue.

[0062] Pressure adjustment: The contact force between the scraper and the belt is changed by oscillation to adapt to different coating viscosities or belt running speeds.

[0063] Easy maintenance: The swing design allows the scraper to temporarily leave the belt surface, making it easy to clean or replace the scraper.

[0064] Reference Figure 1 and Figure 2 In some embodiments, the mounting base 51 proposed in this application is provided with a first connection hole at one end for connecting the adapter plate 52, and the adapter plate 52 is provided with a second connection hole 521 corresponding to the first connection hole. The second connection hole 521 and the first connection hole are rotatably connected by a rotating shaft 6 passing through it.

[0065] In this embodiment, the two ends of the mounting base 51 are respectively provided with first connecting holes, which are aligned with the second connecting holes 521 on the adapter plate 52, and the rotatable connection is achieved by passing through the rotating shaft 6.

[0066] The rotating shaft 6 serves as the rotation axis, enabling the mounting base 51 to swing relative to the adapter plate 52 around the rotating shaft 6, thereby driving the first scraper 41 to adjust its angle or position.

[0067] The first scraper 41 is fixed to the mounting base 51. By swinging the mounting base 51 (rotating around the rotating shaft 6), the tilt angle of the scraper or the contact pressure with the lower return section of the annular belt 22 can be dynamically adjusted to optimize the scraping effect. Specific functions include: Angle adjustment: By swinging, the tilt angle of the first scraper 41 is changed to ensure the best contact angle with the belt surface, improve scraping efficiency, and reduce paint residue.

[0068] Pressure control: By adjusting the swing amplitude, the contact force between the scraper and the belt is controlled to adapt to different coating viscosities, belt running speeds, or surface conditions.

[0069] Reference Figure 1 and Figure 2 In some embodiments, the mounting base 51 proposed in this application is further provided with a locking hole at one end for connecting the adapter plate 52. The locking hole is spaced apart from the mounting hole, and the adapter plate 52 is further provided with an arc groove 522 corresponding to the locking hole. The locking mechanism includes a bolt, and the side of the arc groove 522 facing away from the locking hole is threadedly connected to the locking hole by the bolt.

[0070] In this embodiment, the two adapter plates 52 are respectively located on opposite sides of the annular belt 22 along the conveying direction (i.e., the left and right sides of the belt width), and fixed to the frame 1, providing a stable support foundation for the mounting base 51.

[0071] The mounting base 51 is rotatably connected to the first connecting hole and the second connecting hole 521 of the adapter plate 52 by means of the rotating shaft 6, so that the first scraper 41 can swing around the rotating shaft 6 to adjust its contact angle or pressure with the lower return section of the annular belt 22.

[0072] The locking holes on the mounting base 51 are spaced apart from the first connecting holes, serving as connection points for the locking mechanism. The arc-shaped groove 522 on the adapter plate 52 corresponds to the locking holes, and the arc-shaped path of the arc-shaped groove 522 defines the swing range of the mounting base 51 (i.e., the adjustment angle range of the first scraper 41).

[0073] The design of the arc groove 522 allows the mounting base 51 to swing freely within a certain angle range to adapt to different scraping requirements (such as different coating viscosities or belt running speeds).

[0074] The locking mechanism is fixed by bolts. The bolts are inserted from the side of the arc groove 522 away from the locking hole (i.e., the outside of the adapter plate 52) and are threadedly connected to the locking hole of the mounting base 51 through the arc groove 522.

[0075] When the bolts are tightened, they lock the mounting base 51 and the adapter plate 52, fixing the angle and position of the first scraper 41 and ensuring that it is in close contact with the surface of the lower return section of the annular belt 22 to perform the scraping task.

[0076] When the bolts are loosened, the mounting base 51 can swing along the path of the arc groove 522, allowing adjustment of the tilt angle or contact pressure of the first scraper 41 to optimize the scraping effect.

[0077] Reference Figure 1 and Figure 2 In some embodiments, the automotive parts painting equipment proposed in this application further includes a painting drive mechanism 8 disposed on the frame 1 and located above the conveyor belt, and a painting head 3 disposed at the output end of the painting drive mechanism 8. The painting drive mechanism 8 is used to drive the painting head 3 to move along a preset trajectory.

[0078] In this embodiment, the spraying drive mechanism 8 is fixed to the frame 1 and located above the conveyor belt 2 (i.e. above the upper conveyor section), ensuring that the spraying head 3 can cover the entire area to be sprayed.

[0079] The frame 1 provides stable structural support, ensuring that the spraying drive mechanism 8 is not affected by vibration or displacement during operation, thus maintaining spraying accuracy.

[0080] The spray head 3 is installed at the output end of the spray drive mechanism 8 and moves along a preset trajectory through the power output of the drive mechanism (which may include a motor, robotic arm, guide rail or other transmission system).

[0081] The preset trajectory is designed based on the geometry of the automotive parts and the painting requirements, for example: Linear motion: moving along the conveying direction (or perpendicular to the conveying direction) of conveyor belt line 2, covering long strip-shaped parts (such as decorative strips).

[0082] Curves or complex trajectories: For components with complex shapes (such as dashboards or bumpers), perform multi-axis motion (such as two-dimensional or three-dimensional trajectories) to ensure that the coating evenly covers all surfaces.

[0083] Dynamic adjustment: Adjust the trajectory and spraying parameters (such as spray angle and spray volume) in real time according to the size, shape or coating thickness requirements of the parts.

[0084] Reference Figure 1 and Figure 2 In some embodiments, the spraying drive mechanism 8 proposed in this application includes: The first horizontal drive unit 81 is mounted on the frame 1; The second horizontal drive member 82 is disposed at the output end of the first horizontal drive member 81 and is in a horizontal and vertical state with the first horizontal drive member 81. The lifting drive component 83 is located at the output end of the second horizontal drive component 82, and the spray head 3 is located at the output end of the lifting drive component 83; The first horizontal drive component 81 is used to drive the spray head 3 to move horizontally along the conveying direction of the conveyor belt 2, the second horizontal drive component 82 is used to drive the spray head 3 to move along the direction that crosses the conveyor belt 2, and the lifting drive component 83 is used to drive the spray head 3 to move vertically.

[0085] In this embodiment, the first horizontal drive component 81 (which may be a servo motor, linear guide rail or other linear drive device) is fixed to the frame 1, driving the second horizontal drive component 82, the lifting drive component 83 and the spray head 3 to move horizontally along the conveying direction (X-axis) of the conveyor belt 2.

[0086] The X-axis motion enables the spray head 3 to follow the movement of the parts on the conveyor belt 2, covering the length of the parts and ensuring that the spraying process is synchronized with the belt speed. This is suitable for long strip parts (such as decorative strips) or continuous production needs.

[0087] The second horizontal drive unit 82 is installed at the output end of the first horizontal drive unit 81 and is in a horizontal and vertical state with the first horizontal drive unit 81 (i.e., in the Y-axis direction, spanning the width of the belt).

[0088] The second horizontal drive unit 82 (possibly another set of servo motors or guide rail system) drives the lifting drive unit 83 and the spray head 3 to move along the direction across the conveyor belt line 2, covering the width direction of the parts.

[0089] The Y-axis movement enables the spray head 3 to adapt to parts of different widths (such as dashboards or bumpers) or to perform lateral sweeping on the surface of parts with complex shapes, ensuring that the coating covers all lateral areas.

[0090] The lifting drive component 83 (which may be a cylinder, an electric push rod, or a lifting guide rail) is installed at the output end of the second horizontal drive component 82, and the spray head 3 is directly fixed to the output end of the lifting drive component 83.

[0091] The lifting drive component 83 drives the spray head 3 to move up and down in the vertical direction (Z-axis), adjusting the distance between the spray head 3 and the surface of the part, and controlling the spraying accuracy and coating thickness.

[0092] Z-axis motion adapts to parts of different heights or three-dimensional shapes (such as the curved surfaces of seats or bumpers), ensuring that the spray head 3 maintains the optimal distance from the spray surface, optimizing spray uniformity and paint adhesion.

[0093] A horizontal drive unit (X-axis), a second horizontal drive unit 82 (Y-axis), and a lifting drive unit 83 (Z-axis) work together to coordinate the three-axis motion through a control system (such as a PLC or CNC system), so that the spray head 3 moves along a preset trajectory.

[0094] The preset trajectory is designed based on the geometry of the automotive parts and the painting requirements, for example: Planar trajectory: Combined XY axis motion, covering planar or shallow curved surface components (such as decorative strips).

[0095] 3D trajectory: XYZ axis coordination, adapting to complex three-dimensional shapes (such as the curved surface of a dashboard or bumper), achieving uniform spraying across the entire surface.

[0096] Dynamic adjustment: Adjust the trajectory and spraying parameters (such as spray volume and speed) in real time according to the type of parts or production requirements to improve flexibility.
