Description

Technical Field

[0001] The present application relates to the field of paint spraying equipment, and in particular to a gradient spraying system. Background Art

[0002] Spray painting refers to the process of spraying a protective layer and a decorative layer on the surface of a product to meet functional and aesthetic needs. For some products, the decorative layer needs to be sprayed more carefully in a gradient manner to form a decorative layer with a gradient transition of multiple colors.

[0003] Gradient spray painting mainly sprays paint onto the product surface through a nozzle. The paint sprayed on the product generally forms a solid color area and a gradient area. The solid color area refers to the area with a thicker paint layer, and the gradient area refers to the area with a thinner paint layer. The gradient area is located outside the solid color area. When performing gradient spray painting, the gradient areas of multiple colors of paint are generally mixed and superimposed to form a natural color transition area.

[0004] In the existing related technology, gradient painting is generally completed through a paint processing line, which includes a conveyor belt, a paint spraying tool and a paint spraying assembly. The paint spraying tool is installed on the insertion rod of the conveyor belt, and the paint spraying tool is provided with a fixed rod body for installing the product. There are several paint spraying assemblies, and the several paint spraying assemblies are distributed along the conveying direction of the conveyor belt. The paint spraying assembly includes a mounting frame and a paint spray nozzle. The paint spray nozzle can be installed on the mounting frame in a liftable manner, and the height of the paint spray nozzle of several paint spraying assemblies gradually increases along the conveying direction of the conveyor belt, so that multiple color transition zones formed by superimposing gradient zones are formed in sequence by spraying paint in the horizontal direction through multiple paint spray nozzles. Specifically, the above-mentioned paint spraying processing line can refer to the announcement number CN 211726260 U, and the name is a utility model patent for a multi-color gradient paint spraying device.

[0005] Regarding the above-mentioned related technologies, when the spray nozzle sprays paint on the product in the horizontal direction, the spray range of the paint is approximately triangular, and the farther the paint particles are from the spray nozzle, the larger the dispersion. Compared with products with flat surfaces, the contact area between products with large inclined surfaces and the paint will change, so that the area of ​​the gradient zone formed when the spray nozzle sprays paint on the product will also change, which will cause the height of the color transition zone to shift, that is, move up or down, and cannot meet the needs of the decorative layer with high requirements for gradient spraying precision. Summary of the invention

[0006] In order to prevent the color transition zone formed in the gradient painting process from being easily offset, thereby improving the accuracy of the gradient painting, the present application provides a gradient spraying system.

[0007] The application provides a gradual spraying system that adopts the following technical solution:

[0008] A gradient spraying system comprises a conveying component and a painting component, wherein the conveying component is used to convey a product to be gradiently painted;

[0009] The paint spraying assembly includes a vertical driving member, a rotating driving member and a paint spraying nozzle. The vertical driving member and the rotating driving member are both powered. The vertical driving member is used to drive the paint spraying nozzle to move in a vertical direction, and the rotating driving member is used to drive the paint spraying nozzle to rotate around a horizontal axis. The paint spraying nozzle is used to spray paint on the product to be gradually painted.

[0010] By adopting the above technical solution, after the conveying component conveys the paint to be gradually sprayed to the position of the paint spraying component, the vertical driving component moves the paint spraying nozzle to the required height, and then the product is sprayed with paint through the paint spraying nozzle.

[0011] During the process of spraying paint on a product with a paint spray nozzle, when it is necessary to spray paint on a larger inclined surface, the paint spray nozzle is rotated by rotating the driving member, thereby changing the position of the gradient zone, so that the color transition zone formed by the superposition of multiple gradient zones is not easily offset, thereby improving the accuracy of gradient painting.

[0012] For example, when the height of the gradient zone is too large, the spray nozzle is rotated downward, and when the height of the gradient zone is too small, the spray nozzle is rotated upward. Therefore, by rotating the driving member to change the spray range of the spray nozzle, the generation position of the gradient zone is changed, thereby accurately controlling the generation position of the color transition zone.

[0013] Optionally, the paint spraying assembly further comprises a horizontal driving member, and the horizontal driving member is used to drive the paint spraying nozzle to move in a horizontal direction, and the horizontal driving member is powered.

[0014] By adopting the above technical solution, after the paint spray nozzle rotates under the action of the rotating drive member, the horizontal drive member performs fine-tuning and compensation according to the spraying range of the paint spray nozzle, so that the color transition effect of the gradient zone located on the inclined surface is close to the color transition effect of the gradient zone located on the flat surface, thereby ensuring that the color transition zone can maintain a high degree of consistency throughout the product.

[0015] Optionally, the vertical driving member and the horizontal driving member are both linear modules, and the rotary driving member is a servo motor;

[0016] The vertical driving member is mounted on the mover of the horizontal driving member, and the rotary driving member is mounted on the mover of the vertical driving member;

[0017] Or the horizontal driving member is mounted on the mover of the vertical driving member, and the rotary driving member is mounted on the mover of the horizontal driving member.

[0018] The adoption of the above technical solution is beneficial to improving the accuracy of the gradient spraying system while reducing the cost of the gradient spraying system.

[0019] Optionally, the gradient spraying system further comprises a visual detection component, and the visual detection component is used to detect the contour of the gradient area.

[0020] By adopting the above technical solution, when the paint nozzle is painting the product, the visual detection component follows the scan and identifies the outline of the gradient zone. When the outline of the gradient zone exceeds the preset range, the visual detection component sends a feedback signal to the paint spraying component, so that the paint spraying component calibrates its own parameters, thereby further ensuring the accuracy of the gradient painting.

[0021] Optionally, the paint spraying assembly further includes a vertical calibrator and a horizontal calibrator, both of which are unpowered, the vertical calibrator is used to drive the paint spraying nozzle to move in a vertical direction, and the horizontal calibrator is used to drive the paint spraying nozzle to move in a horizontal direction.

[0022] By adopting the above technical solution, a trial run is carried out before gradient painting, and the staff manually calibrates the parameters through the vertical calibrator and the horizontal calibrator according to the painting effect of the product, so as to ensure the accuracy of the gradient spraying system when it is officially put into operation.

[0023] Optionally, the conveying assembly includes a conveyor belt and a painting tool, and the painting tool is installed on the conveyor belt;

[0024] The painting tooling comprises a conveying base and a fixed rod body, wherein the fixed rod body is used to mount the product to be gradually painted, and the fixed rod body is rotatably matched with the conveying base;

[0025] The gradient spraying system further comprises a rotating assembly, and the rotating assembly is used for driving the fixed rod to rotate.

[0026] By adopting the above technical solution, during the process of gradient painting of the product, the rotating component drives the fixed rod to rotate, thereby driving the product fixedly mounted on the fixed rod to rotate, so that the paint spray nozzle can paint all surfaces of the product without large-scale movement, which is beneficial to reducing the cost of the paint spray component.

[0027] Optionally, the fixed rod body is installed with a transmission worm wheel, the conveying base is installed with a transmission worm, the transmission worm is meshed with the transmission worm wheel, and the transmission assembly drives the fixed rod body to rotate through the transmission worm.

[0028] By adopting the above technical solution, when the transmission component does not drive the transmission worm to rotate, the transmission worm wheel and the fixed rod body are difficult to rotate, so that the products to be gradient painted are not easy to rotate at will when being conveyed by the conveying component, thereby ensuring that several products are in a consistent or close initial state when arriving at the location of the paint spraying component, thereby reducing the difficulty of identification and calibration and ensuring the accuracy and of gradient painting.

[0029] In addition, when the rotating component rotates the fixed rod through the transmission worm, a deceleration effect and a torque increase effect are generated between the transmission worm and the transmission worm wheel, which is beneficial for the rotating component to rotate the fixed rod and the product accurately at a preset angular velocity according to the shape of the product, thereby improving the applicability and accuracy of the gradient spraying system.

[0030] Optionally, the painting tool further comprises a transmission plug-in, the transmission plug-in is provided with a transmission slot, and when the transmission plug-in rotates, the fixed rod body rotates;

[0031] The rotating assembly includes a transmission plug, a rotating drive and a locking drive. The transmission plug can be plugged in and out of the transmission slot. The rotating drive is used to drive the transmission plug to rotate. The locking drive is used to drive the transmission plug to move toward or away from the transmission slot.

[0032] By adopting the above technical solution, when the fixed rod body needs to be rotated, the locking driving member inserts the transmission plug into the transmission slot, and then the rotating driving member drives the transmission plug to rotate, driving the transmission plug to rotate, thereby causing the fixed rod body to rotate. When the fixed rod body needs to be kept stationary, the transmission plug is kept away from the transmission slot, which is convenient and quick.

[0033] In addition, after the transmission plug is inserted into the transmission slot, the fixed rod will find it difficult to continue moving along the conveying direction of the conveying component, which is conducive to ensuring that the products to be gradient painted are accurately positioned at the preset position of the painting component for painting, thereby further ensuring the accuracy of gradient painting.

[0034] Optionally, the rotating assembly also includes a mounting base, the rotating driving member is a motor, the locking driving member is a cylinder, the rotating driving member slides in the horizontal direction and fits in the mounting base, the locking driving member is installed on the mounting base, the output rod of the locking driving member is installed on the rotating driving member, and the transmission plug is installed on the output shaft of the rotating member.

[0035] The adoption of the above technical solution is beneficial to improving the accuracy of the gradient spraying system while reducing the cost of the gradient spraying system.

[0036] Optionally, the transmission worm is provided with a reset elastic member, and the reset elastic member is installed on the conveying base.

[0037] By adopting the above technical solution, when the transmission worm is not driven to rotate by the transmission assembly, the reset elastic member keeps the transmission worm in the initial state, which is beneficial to ensure that the product to be gradient painted always maintains the preset initial state during the conveying process, thereby ensuring the accuracy of the gradient painting.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. After the conveying component transports the paint to be gradually sprayed to the location of the paint spraying component, the vertical drive component moves the paint spraying nozzle to the required height, and then the product is sprayed with paint through the paint spraying nozzle;

[0040] When the paint spraying nozzle is painting the product, when it is necessary to paint a slope with a large inclination, the paint spraying nozzle is rotated by rotating the driving member, thereby changing the position of the gradient zone, so that the color transition zone formed by the superposition of multiple gradient zones is not easily offset, thereby improving the accuracy of gradient painting;

[0041] 2. After the paint spray nozzle rotates under the action of the rotary drive member, the horizontal drive member performs fine adjustment and compensation according to the spray range of the paint spray nozzle, so that the color transition effect of the gradient zone on the inclined surface is close to the color transition effect of the gradient zone on the flat surface, thereby ensuring that the color transition zone can maintain a high degree of consistency throughout the product.

[0063] Reference Figure 2 The conveying assembly 1 includes a conveyor belt and a painting tool, and the painting tool can be plugged into and installed on the positioning rod of the conveyor belt. Figure 4 , Figure 5 as well as Figure 6 The painting tooling includes a conveying base 11, a fixed rod body 12 and a transmission plug-in 13. A base chamber 101 is provided inside the conveying base 11. The bottom of the fixed rod body 12 is rotatably matched with the inner wall of the base chamber 101. The top of the fixed rod body 12 is used to fix and install the product to be gradually sprayed with paint, so that the product can rotate with the fixed rod body 12.

Combined with Figure 4 and Figure 5 The transmission plug 42 can be plugged in and out of the transmission slot 131, and the end of the transmission plug 42 away from the rotating drive member 43 is chamfered, and the outer peripheral surface of the transmission plug 42 is provided with a plurality of protrusions, and the plurality of protrusions are distributed in an "*" shape, so that after the transmission plug 42 is inserted into the transmission slot 131, the transmission plug-in 13 is driven to rotate through the transmission plug 42, thereby overcoming the elastic force of the reset elastic member 112 and rotating through the transmission worm 111, the transmission worm wheel 121 and the fixed rod body 12, and locking the position of the conveying base 11 through the transmission plug 42.

[0067] The implementation principle of a gradient spraying system in the embodiment of the present application is as follows:

[0068] Reference Figure 8 When the paint spray nozzle 26 sprays paint from point O1 to the flat surface L1, a gradient area S1, a solid color area S2 and a gradient area S3 are formed. The gradient area S1, the solid color area S2 and the gradient area S3 are distributed in sequence along the vertical direction, and the color transition area generated when the product is gradient painted is formed based on the gradient area S1, and the height dimension of the gradient area S1 corresponding to the spray point A1 formed by the paint spray nozzle 26 is H1.

[0069] Reference Fig. 9 When the spray nozzle 26 sprays paint from point O1 to the inclined surface L2, a gradient area S10, a fixed color area S20 and a gradient area S30 are formed. The gradient area S10, the fixed color area S20 and the gradient area S30 are sequentially distributed along the vertical direction, and the height dimension of the gradient area S10 corresponding to the top of the spray formed by the spray nozzle 26 is H2. Figure 8 and Fig. 9It can be known that: H2 is greater than H1, and the width of S10 is greater than that of S1, which causes the gradient area to move upward and expand. In addition, since point A1 does not contact the inclined surface L2, and point A2, which is farther away from point O1 than point A1, is released from the inclined surface L2, the color at the position of S10 is thinner than the color at the position of S1, that is, there is a color difference between the gradient area of ​​the flat surface L1 and the gradient area of ​​the inclined surface L2.

[0070] Reference Fig.10 , the product to be gradually painted is transported to the position of the paint spray nozzle 26 via the conveyor belt, and after being locked in position by the transmission plug 42, the paint spray nozzle 26 undergoes a vertical displacement y and a horizontal displacement x in the vertical direction under the action of the vertical drive member 21 and the horizontal drive member 22, so that the paint spray nozzle 26 moves from point O1 to point O2. In addition, the rotating drive member 25 also rotates the direction of the paint spray nozzle 26 from top to bottom by α°, so that the spray point A1 formed by the paint spray nozzle 26 is transferred to the position of A3 and contacts the inclined surface L2. At this time, when the paint spray nozzle 26 sprays paint on the inclined surface, a gradual change area S11, a fixed color area S21 and a gradual change area S31 are formed. Combined with the comparison Figure 8 and Fig.10 It can be known that the width dimension of the gradient zone S11 is consistent with that of the gradient zone S1, and the height dimension H3 of the top of the gradient zone S11 is consistent with H1, and the spray point A1 formed by the paint spray nozzle 26 corresponds to the top of the gradient zone, so that the gradient zone S11 formed on the inclined surface L2 and the gradient zone S1 formed on the flat surface L1 maintain a large similarity in width, height and color, so that the color transition zone formed in the gradient painting process is not easy to shift, thereby improving the accuracy of the gradient painting.

[0071] In addition, when the paint spray nozzle 26 is painting the product, the transmission plug 42 drives the transmission plug-in 13, the transmission worm 111, the transmission worm wheel 121 and the fixed rod body 12 to rotate, so that each surface of the product can form a qualified gradient paint decoration layer.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
