[0048] In modern industrial production, spraying is a widely used and important process that can provide anti-corrosion, decorative, or functional coatings to various surfaces. With the continuous improvement of automation, workpieces are generally transported through conveyor structures during spraying operations, and these conveyor structures directly affect the quality of the spraying.

[0049] Most existing conveyor structures used for spraying work employ straight conveyor belts to transport workpieces during the spraying process, but this can lead to axial coating buildup and uneven spraying.

[0050] This invention proposes a conveying structure for spraying operations to improve spraying uniformity.

[0051] Please see Figure 1 and Figure 2In one embodiment, the conveying structure for spraying includes a linear conveying assembly 100, a fixture 200, and a rotating assembly; one end of the fixture 200 is rotatably mounted on the linear conveying assembly 100, and the other end of the fixture 200 is provided with a mounting position; a set of rotating assemblies is provided on both sides of the fixture 200, and the two sets of rotating assemblies rotate in opposite directions and both abut against the fixture 200 to drive the fixture 200 to rotate.

[0052] The linear conveyor assembly 100 is used to drive the workpiece 500 in linear motion, thereby conveying the workpiece 500. The workpiece 500 can be a cap, bottle, or other material; no limitation is placed here. The fixture 200 is used to support and fix the workpiece 500. The fixture 200 has a mounting position where the workpiece 500 is fixed. The linear conveyor assembly 100 drives the fixture 200 in linear motion, thereby moving the workpiece 500. The fixture 200 can rotate relative to the linear conveyor assembly 100. In one embodiment, multiple fixtures 200 are provided, all rotatably mounted on the linear conveyor assembly 100, and are spaced apart and evenly distributed. Of course, in other embodiments, only one fixture 200 may be provided. The number of fixtures 200 can be flexibly set according to actual needs; no limitation is placed here.

[0053] The rotating components are used to drive the fixture 200 to rotate. In one embodiment, the rotating components are located above the linear conveyor assembly 100 and on both sides of the fixture 200, with the two rotating components symmetrically arranged. The two rotating components rotate in opposite directions and can both abut against the fixture 200 during rotation, applying a driving force to the fixture 200, causing the fixture 200 to rotate, and in turn, causing the workpiece 500 to rotate. Thus, by providing two sets of rotating components, while driving the fixture 200 to rotate, it is possible to ensure that the fixture 200 rotates smoothly, avoiding imbalance of driving force on one side that could affect the coating quality; and since the two sets of rotating components rotate in opposite directions, they cooperate with each other to avoid mutual interference of driving forces on both sides, ensuring that the fixture 200 can be easily driven to rotate, thus improving the reliability of the conveyor structure used for coating operations.

[0054] The technical solution of this utility model involves setting a linear conveyor assembly 100, a fixture 200, and a rotating assembly in the conveyor structure used for spraying. One end of the fixture 200 is rotatably mounted on the linear conveyor assembly 100, and the other end of the fixture 200 has a mounting position. A set of rotating assemblies is provided on each side of the fixture 200, with the two sets of rotating assemblies rotating in opposite directions and both abutting against the fixture 200 to drive its rotation. Compared to the existing conveyor structure that only has a linear conveyor belt, the technical solution of this utility model, by setting the rotating assembly, allows the fixture 200 to rotate while the linear conveyor assembly 100 drives it in linear motion, thereby driving the workpiece 500 to rotate. This facilitates omnidirectional spraying of the workpiece 500 and improves the uniformity of the spraying.

[0055] Please see Figure 1 and Figure 2 In one embodiment, the rotating assembly includes a bracket 310 and a rotating wheel 320. The bracket 310 is disposed on one side of the fixture 200. The rotating wheel 320 is rotatably disposed on the bracket 310 and abuts against the fixture 200. The central axis of the rotating wheel 320 is perpendicular to the movement direction of the linear transmission assembly 100.

[0056] In one embodiment, each group of rotating components includes multiple rotating wheels 320, and all rotating wheels 320 in each group are evenly spaced along the movement direction of the linear conveying component 100. Further, in one embodiment, all rotating wheels 320 in each group of rotating components rotate in the same direction, the rotating wheels 320 in two groups of rotating components are symmetrically distributed, and the rotating wheels 320 in the two groups of rotating components rotate in opposite directions. Of course, in other embodiments, each group of rotating components may have only one rotating wheel 320; the number of rotating wheels 320 is not limited here. In one embodiment, the rotating wheel 320 is rotatably mounted on the bracket 310 via bearings and a positioning shaft, the extension direction of the positioning shaft being perpendicular to the movement direction of the linear conveying component 100. Of course, in other embodiments, the rotating wheel 320 may also be rotatably mounted on the bracket 310 via gears or the like; this is not limited here. In one embodiment, the bracket 310 is provided with a shielding part 311, located above the rotating wheel 320, which can prevent paint from falling onto the rotating wheel 320 and provide protection for the rotating wheel 320. Of course, in other embodiments, the shielding part 311 may not be provided, and there is no limitation here.

[0057] The technical solution of this utility model embodiment, by setting a rotating wheel 320, allows the jig 200 to rotate, which in turn drives the workpiece 500 to rotate, thus improving the uniformity of spraying. Furthermore, the central axis of the rotating wheel 320 is perpendicular to the direction of motion of the linear conveyor assembly 100, enabling the jig 200 to rotate while the linear conveyor assembly 100 drives the jig 200 in linear motion, ensuring the realization of the rotating assembly's function.

[0058] Please see Figure 1 and Figure 2 In one embodiment, the rotating assembly further includes a drive wheel 340, a timing belt 350, and a first power component 360. The drive wheel 340 is mounted on the bracket 310. The timing belt 350 drives the drive wheel 340 and the rotating wheel 320. The rotating wheel 320 abuts against the fixture 200 via the timing belt 350. The first power component 360 is driven by the drive wheel 340.

[0059] In one embodiment, each set of rotating components includes a drive pulley 340, a timing belt 350, and a first power component 360. The drive pulley 340 is located at one end of the bracket 310, and the timing belt 350 transmits and connects the drive pulley 340 and multiple rotating pulleys 320, such that all rotating pulleys 320 in each set of rotating components rotate in the same direction. The two drive pulleys 340 rotate in opposite directions to ensure that the two sets of rotating components rotate in opposite directions. In one embodiment, the first power component 360 is configured as a motor, driven and connected to the drive pulley 340 via a transmission belt. Of course, in other embodiments, the first power component 360 may also be configured as a motor or a cylinder, etc., without limitation. Further, in one embodiment, the rotating component also includes a tension pulley 370, which is located at the other end of the bracket 310 and opposite to the drive pulley 340. The tension pulley 370 is used to adjust the tension of the timing belt 350. Of course, in other embodiments, each set of transmission components may also be provided with multiple drive pulleys 340 or multiple first power components 360, without limitation.

[0060] The technical solution of this utility model embodiment, by setting a synchronous belt 350, allows the rotating wheel 320 to abut against the fixture 200 via the synchronous belt 350. The synchronous belt 350 can simultaneously abut against multiple fixtures 200 to drive the multiple fixtures 200 to rotate, thereby improving rotation efficiency. In addition, the synchronous belt 350 compensates for the gap between two adjacent rotating wheels 320 and avoids hard contact between the rotating wheel 320 and the fixture 200. The rotating wheel 320 can provide support for the synchronous belt 350 to ensure that the synchronous belt 350 abuts against the fixture 200, so that the synchronous belt 350 drives each fixture 200 to rotate evenly, further ensuring the smooth rotation of the fixture 200 and improving the reliability of the conveyor structure used for spraying operations.

[0061] Please see Figure 2 and Figure 3 In one embodiment, the fixture 200 includes a rotating body 210, a support rod 220, and a fixture body 230. The rotating body 210 is rotatably mounted on the linear conveying assembly 100 and abuts against the rotating assembly. The support rod 220 is located at one end of the rotating body 210 away from the linear conveying assembly 100. The fixture body 230 is detachably connected to the fixture 200 rod and has a mounting position.

[0062] In one embodiment, the surface of the rotating body 210 is provided with multiple anti-slip textures, which are arranged circumferentially along the rotating body 210 and each anti-slip texture extends axially along the rotating body 210. The synchronous belt 350 abuts against the anti-slip textures to drive the fixture 200 to rotate. Of course, in other embodiments, the surface of the rotating body 210 may be roughened or anti-slip sleeves may be provided to increase the frictional resistance of the contact portion between the synchronous belt 350 and the rotating body 210. This is not a limitation. In one embodiment, the end of the rotating body 210 away from the linear transmission assembly 100 is provided with an interface, and the support rod 220 is provided with a plug-in portion. Both the plug-in portion and the interface are provided with abutment planes. The plug-in portion is inserted into the interface, and the abutment planes can prevent the support rod 220 from rotating relative to the rotating body 210. Of course, in other embodiments, the support rod 220 and the rotating body 210 may also be integrally formed or connected by screwing, welding, or snap-fitting. This is not a limitation. In one embodiment, the conveying structure for spraying further includes a limiting plate 400, which is movably sleeved on the support rods 220 of the plurality of fixtures 200. In one embodiment, the limiting plate 400 is arranged parallel to the linear conveying assembly 100, and the limiting plate 400 is provided with limiting holes, through which the support rods 220 pass and can rotate relative to the limiting holes. Of course, in other embodiments, limiting chains or the like may also be provided, and this is not a limitation.

[0063] In one embodiment, the fixture body 230 includes a sleeve portion 231 and a mounting portion 232. The sleeve portion 231 is detachably sleeved on the support rod 220. The mounting portion 232 is located at one end of the sleeve portion 231 and has a limiting protrusion 233 forming a mounting position. Specifically, in one embodiment, a ring of limiting protrusions 233 is formed around the side of the mounting portion 232 opposite to the sleeve portion 231. The limiting protrusions 233 are configured to conform to the shape of the workpiece 500, allowing the workpiece 500 to be tightly sleeved on the outer periphery of the limiting protrusions 233, thereby fixing the workpiece 500. In one embodiment, the limiting protrusions 233 have a certain deformation capability to facilitate close contact with the workpiece 500 and prevent the workpiece 500 from rotating relative to the mounting portion 232. In one embodiment, the sleeve portion 231 is provided with an air extraction hole, and the mounting portion 232 is provided with an adsorption hole. The air extraction hole and the adsorption hole are connected to adsorb the workpiece 500 and further fix the workpiece 500. Of course, in other embodiments, the fixture body 230 may only be provided with a limiting protrusion 233 or an adsorption hole, and the fixture body 230 may also fix the workpiece 500 by providing a suction cup or the like. There are no restrictions here.

[0064] The technical solution of this utility model embodiment, by setting anti-slip textures on the rotating body 210, can increase the friction between the synchronous belt 350 and the rotating body 210, reducing the driving force required for the synchronous belt 350 to drive the rotating body 210 to rotate. The bottom of the fixture 200 is limited by the linear conveyor assembly 100. By setting a limiting plate 400, the top of the fixture 200 can be limited to prevent the fixture 200 from shaking and improve the stability of the fixture 200. By setting a detachably connected support rod 220 and fixture body 230, the fixture body 230 can be flexibly replaced according to actual needs, improving the flexibility of the conveyor structure used for spraying work and expanding the application range of the conveyor structure used for spraying work.

[0065] Please see Figure 2 and Figure 3 In one embodiment, the linear conveying assembly 100 includes a conveying chain 110 and a second power component. The conveying chain 110 is provided with a fixed shaft 140, and the rotating body 210 is rotatably sleeved on the fixed shaft 140. The second power component is driven to connect with the conveying chain 110, so that the conveying chain 110 moves in a linear motion.

[0066] Specifically, in one embodiment, the rotating body 210 is hollow, and two bearings are spaced apart inside the rotating body 210. One end of the fixed shaft 140 is fixed to the conveyor chain 110, and the other end of the fixed shaft 140 extends into the rotating body 210 and is rotatably connected to the rotating body 210 through the two bearings. Of course, in other embodiments, one or more bearings may be provided, which is not limited here. In one embodiment, the fixed shaft 140 is configured as a screw, and a support member 160 is provided below the conveyor chain 110. The screw passes through the support member 160 and the conveyor chain 110 in sequence, and the head of the screw is located below the conveyor chain 110. The screw is fixed to the conveyor chain 110 and rotatably connected to the rotating body 210. A second power member drives the conveyor chain 110 to drive the support member 160 and the fixture 200 to perform linear motion. The second power member may be configured as a motor, cylinder, or hydraulic cylinder, etc. The second power member is directly connected to the conveyor chain 110 or driven by a gear rack or worm gear, etc., which is not limited here. Of course, in other embodiments, the second power member may also be driven to connect with the support member 160, so that the support member 160 drives the transmission chain 110 to move in a straight line. This is not a limitation.

[0067] Please see Figures 1 to 3 In one embodiment, the linear conveying assembly 100 further includes a support platform 120 and a plurality of rollers 130. The support platform 120 is located below the conveyor chain 110. The plurality of rollers 130 are rotatably located on the side of the conveyor chain 110 and roll in contact with the support platform 120. The plurality of rollers 130 can roll along the support platform 120.

[0068] In one embodiment, multiple rollers 130 are provided on both sides of the conveyor chain 110, with each roller 130 corresponding to the other on both sides. In another embodiment, a fixed rod is provided on the conveyor chain 110, and the rollers 130 are rotatably mounted at both ends of the fixed rod. In another embodiment, the linear conveyor assembly 100 further includes a support base 150, and a carrying platform 120 is disposed on the support base 150. Two carrying platforms 120 are arranged parallel to each other on the support base 150, and the rollers 130 on both sides of the conveyor chain 110 respectively roll in contact with one carrying platform 120. In another embodiment, a limiting block 170 is provided on the side of the two carrying platforms 120 that are close to each other, and a gap is formed between the two limiting blocks 170 to allow the support member 160 to pass through. The limiting block 170 can abut against the support member 160 to prevent the movement direction of the conveyor chain 110 from deviating and to ensure the normal operation of the conveyor chain 110. Of course, in other embodiments, the roller 130 may be provided only on one side of the conveyor chain 110, or the rollers 130 on both sides may be staggered. This is not a limitation. Similarly, in other embodiments, only one support platform 120 may be provided. This is not a limitation.

[0069] The technical solution of this embodiment of the utility model, by setting a fixed shaft 140, realizes the rotational connection between the rotating body 210 and the conveyor chain 110, ensuring the rotational movement of the fixture 200 while positioning it. By setting the roller 130 and the supporting platform 120, the frictional force during the movement of the conveyor chain 110 is reduced, ensuring the stable operation of the conveyor chain 110 and further improving the reliability of the conveyor structure used for spraying.

[0070] This utility model also proposes a spraying system, including the conveying structure for spraying work described in the above embodiments. The specific structure of the conveying structure for spraying work is as described in the above embodiments. Since this spraying system adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0071] In one embodiment, the spraying system further includes a spray gun array positioned above a conveyor structure used for spraying. While the conveyor structure operates, the spray gun array sprays the workpiece from all directions. In one embodiment, the spraying array includes four fixed spray guns and four oscillating spray guns. The fixed spray guns are responsible for the main coating surface, while the oscillating spray guns are used for supplementary coating of the workpiece's edges and corners. In one embodiment, the oscillating spray guns are equipped with a drive unit that drives the oscillating spray guns to move, ensuring the accuracy of supplementary coating. Of course, in other embodiments, only one or more fixed and oscillating spray guns may be provided; this is not a limitation. In one embodiment, the spraying system further includes a controller and a laser thickness gauge. The controller is electrically connected to the laser thickness gauge and the spray gun array. The laser thickness gauge is used to detect and provide feedback on the coating thickness of the workpiece in real time, and the controller can adjust the spraying parameters of the spray gun array in a timely manner based on the information fed back by the laser thickness gauge. Furthermore, in one embodiment, the spraying system also includes a spectrophotometer, which is electrically connected to the controller. The spectrophotometer can detect the color data of the coating surface of the workpiece in real time and feed it back to the controller. The controller will calibrate the spraying color of the spray gun array in a timely manner based on the feedback color information.

[0072] Thus, the combination of oscillating and fixed spray guns can further improve the uniformity of spraying. By setting up a laser thickness gauge, the spraying thickness can be adjusted in a timely manner, improving the consistency of the spraying thickness; by setting up a spectrophotometer, color difference can be automatically calibrated, reducing the impact of color difference and improving the consistency of spraying color, thereby improving the intelligence and reliability of the spraying system.
