Description

Technical Field

[0001] This invention relates to the field of spraying technology, and more specifically to an intelligent spraying system. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high flow low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc.

[0003] As is well known, in traditional spray painting production lines, when spraying tubular workpieces, the production line usually transports individual tubular workpieces continuously for sequential spraying. During spraying, the tubular workpiece needs to be rotated or the position of the robot arm needs to be adjusted to achieve multi-angle spraying of the tubular workpiece. Furthermore, the tubular workpiece needs to be stopped on the production line during spraying to complete the spraying process. Obviously, the traditional spray painting system prolongs the spraying time per unit tubular workpiece, thereby reducing the spraying efficiency of the spray painting system.

[0004] In view of this, in order to improve the above-mentioned technical problems, the present invention provides an intelligent spraying system, which improves the above-mentioned technical problems. Summary of the Invention

During spraying, the tubular workpiece needs to be rotated continuously or the position of the robot arm needs to be adjusted to achieve multi-angle spraying of the tubular workpiece. Moreover, the tubular workpiece needs to be stopped on the production line to complete the spraying.

[0016] A rubber block is mounted on the other end of the spring, and the surface of the rubber block is arc-shaped.

[0017] Preferably, the spraying assembly includes:

[0018] The cover is hinged to one end of the second support near the conveyor belt;

[0019] A partition plate is installed above the cover, and a cavity is formed between the partition plate and the top of the cover.

[0020] Pipe No. 1 is located inside the cover. The upper end of Pipe No. 1 passes through the top of the cover and is rotatably connected to the center of the top of the cover. Pipe No. 1 is rotatably connected to the partition plate.

[0021] Pipe No. 2 is located inside pipe No. 1 and its outer wall is slidably connected to the inner wall of pipe No. 1.

[0022] Multiple No. 3 tubes are arranged circumferentially inside the cover. The upper end of each No. 3 tube passes through the top of the cover and is rotatably connected to the top of the cover. Each No. 3 tube is rotatably connected to a partition plate.

[0023] Preferably, a second motor is installed above the cover, and the output shaft of the second motor passes through the top of the cover and is located inside the cavity. The output shaft is rotatably connected to the top of the cover.

[0024] Preferably, the cavity is provided with a first gear, multiple second gears, and a third gear;

[0025] The first gear is installed on the outer wall of the first tube;

[0035] The beneficial effects of this invention are as follows:

[0036] 1. This invention provides an intelligent spraying system. A first motor drives a first disc to rotate, allowing the spraying components to rotate synchronously with the support components on the conveyor belt. This enables a single spraying component to continuously spray multiple tubular workpieces. Simultaneously, multiple spraying components and transmission components are distributed around the circumference above the first disc, allowing the multiple spraying components to alternately spray multiple tubular workpieces. This ensures that the tubular workpieces on the support components are sprayed during transportation, thereby reducing the spraying time per unit of ceramic and improving the spraying efficiency of the spraying equipment.

[0037] 2. This invention provides an intelligent spraying system. When the diameter of the tubular workpiece is different, the operator only needs to insert the tubular workpieces of different diameters into the upper end of the support frame to spray the tubular workpieces of different diameters without stopping the entire production line for replacement, thereby reducing the labor intensity of the personnel.

[0038] 3. This invention provides an intelligent spraying system. When the length of the tubular workpiece is different, the operator only needs to pull or push the pipe to control the vertical distance between the second pipe and the first pipe. This controls the through holes on the outer wall of the second pipe that can be blocked. For example, when the tubular workpiece is small, the operator pushes the pipe to move the second pipe downwards inside the first pipe. The through hole above the first pipe will be blocked by the outer wall of the second pipe, preventing paint from being sprayed out. Conversely, the through hole below the first pipe will not be blocked by the outer wall of the second pipe, so paint can be sprayed onto the outside of the first pipe. This allows for spraying according to the length of the tubular workpiece, reducing paint waste.

[0039] 4. The present invention provides an intelligent spraying system that uses a cover to enclose the tubular workpiece inside the cover to complete the spraying, so that the tubular workpiece can be sprayed in a closed environment, thereby reducing the phenomenon of paint splashing everywhere during spraying.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] To better understand the above technical solutions, the following will provide a detailed explanation of the above technical solutions in conjunction with the accompanying drawings and specific implementation methods;

[0050] The present invention provides an intelligent spraying system, including a conveyor belt 1, and further comprising:

[0051] A support assembly is arranged above the conveyor belt 1 to support the workpiece on the conveyor belt 1.

[0052] Chassis 2, wherein the chassis 2 is placed horizontally on the working plane and a No. 1 motor 21 is fixedly installed on the surface;

[0053] The first disk 3 is horizontally fixedly installed on the output end of the first motor 21;

[0054] The first bracket 31 is vertically fixedly installed at the center of the first turntable. The upper circumference of the first bracket 31 is provided with evenly arranged first mounting holes 311. An electric telescopic rod 312 is fixedly installed in the first mounting hole 311.

[0055] The second bracket 32 ​​is rotatably mounted above the first disc 3 via the third bracket 33. One end of the second bracket 32 ​​is elastically connected to the electric telescopic rod 312 via an elastic steel rope, and the other end of the second bracket 32 ​​is connected to the spraying assembly.

[0056] A spraying assembly, located above a support assembly, is used to spray paint the workpiece on the support assembly.

[0057] By vertically placing multiple tubular workpieces on the support assembly, the support assembly can support multiple tubular workpieces simultaneously. Then, the first motor 21 is energized, causing the output end of the first motor 21 to drive the first disc 3 to rotate relative to the chassis 2 (i.e., the working plane, such as the factory floor). The rotating first disc 3 will drive the first bracket 31, the second bracket 32 ​​and the spraying assembly to rotate synchronously. Since the conveyor belt 1 is in a non-working state (i.e., a stopped state) at this time, the spraying assembly will rotate relative to the conveyor belt 1.

[0058] When the spraying assembly rotates close to the support assembly, the electric telescopic rod 312 is energized, causing its output end to move downward relative to the first bracket 31. This allows the elastic steel cable to pull the end of the second bracket 32 ​​near the electric telescopic rod 312 downward relative to the first bracket 31. Then, the second bracket 32 ​​is rotated and mounted above the first disc 3 via the third bracket 33, causing its other end to move upward. This causes the spraying assembly to move upward relative to the conveyor belt 1. Once the spraying assembly has moved upward, it will continue to rotate with the first disc 3.

[0059] When the spraying assembly rotates to the top of the support assembly (i.e., above the tubular workpiece), the output end of the electric telescopic rod 312 is moved upward relative to the first bracket 31 by controlling the electric telescopic rod 312, which in turn causes the spraying assembly to move downward. The downward-moving spraying assembly will cover all the tubular workpieces on the support assembly inside the spraying assembly. After the spraying assembly has completed its downward movement, it will start to spray all the tubular workpieces inside it simultaneously from multiple angles.

[0060] Because the end of the second support 32 closest to the first support 31 moves in an arc shape during its up-and-down rotation, and there is displacement in the horizontal direction, in order to avoid jamming the telescopic end of the electric telescopic rod 312, a gap is maintained between the telescopic end of the electric telescopic rod 312 and the end of the second support 32 closest to the first support 31, and they are connected by an elastic steel rope. In this way, during the up-and-down rotation, the elastic deformation of the elastic steel rope compensates for the horizontal displacement change of the end of the second support 32 closest to the first support 31, and avoids jamming between it and the telescopic end of the electric telescopic rod 312.

[0061] By controlling the rotation direction and speed of the conveyor belt 1 and the rotation direction and speed of the first disc 3 to the same speed, the spraying component is aligned with the rotation direction and speed of the conveyor belt 1. Therefore, the tubular workpiece will be continuously sprayed by the spraying component during transportation. Then, multiple spraying components will alternately spray multiple workpieces, thereby avoiding the need for the tubular workpiece to stop on the production line to complete the spraying.

[0062] Compared to traditional spraying systems, this invention, through the linkage between the spraying components and the support components, allows multiple tubular workpieces to be sprayed simultaneously from multiple angles in a closed environment. Furthermore, by having multiple spraying components alternately spray multiple workpieces, the need for the tubular workpieces to stop on the production line during spraying is avoided. Therefore, in summary, this invention shortens the spraying time per unit tubular workpiece, thereby improving the spraying efficiency of the spraying system.

[0063] In one embodiment of the present invention, the support assembly includes: the second disc 41 is fixedly mounted on the conveyor belt 1; a plurality of support frames 42 are rotatably mounted inside the second disc 41, and the upper circumference of the support frame 42 is provided with uniformly arranged second mounting holes 421, and a spring 422 is fixedly mounted in the second mounting holes 421; a rubber block 423 is fixedly mounted on the other end of the spring 422, and the surface of the rubber block 423 is arc-shaped.

[0064] The worker presses the rubber block 423, squeezing it into the second mounting hole 421. Then, the worker vertically inserts the tubular workpiece into the upper end of the support frame 42, so that the upper end of the support frame 42 is inside the tubular workpiece. When the tubular workpiece is vertically inserted into the upper end of the support frame 42, the rubber block 423 will pop out from the second mounting hole 421 due to the spring 422. The surface of the popped rubber block 423 will contact the inner wall of the tubular workpiece. At the same time, the rubber block 423 will also support the tubular workpiece on the upper end of the support frame 42 due to the pushing force of the spring 422 and the friction of its own surface. By evenly arranging multiple rubber blocks 423 on the upper end of the support frame 42, the supporting force on the tubular workpiece is increased, reducing the occurrence of the tubular workpiece slipping off the upper end of the support frame 42.

[0065] By setting the surface of the rubber block 423 to be arc-shaped, it is convenient for workers to press the rubber block 423 and for inserting tubular workpieces.

[0066] The tubular workpiece supported on the upper end of the support frame 42 is rotatably mounted inside the second disc 41, so that the workpiece can rotate relative to the conveyor belt 1.

[0067] Furthermore, because the cover 5 has a horizontal displacement during its downward rotation, the diameter of the second disk 41 is set to be smaller than the opening diameter of the cover 5. In this way, during the process of the cover 5 rotating downward to cover the second disk 41 and the tubular workpiece therein, the distance difference between the inner wall of the cover 5 and the outer wall of the second disk 41 can effectively compensate for the horizontal displacement of the cover 5, and avoid the phenomenon of collision between the cover 5 and the tubular workpiece during the downward rotation.

[0068] In one embodiment of the present invention, the spraying assembly includes: a cover 5 hinged to one end of a second support 32 near the conveyor belt 1; a partition plate 51 fixedly installed above the cover 5, forming a chamber 6 between the upper part of the partition plate 51 and the lower part of the top of the cover 5; a first tube 52 located inside the cover 5, the upper end of the first tube 52 penetrating the top of the cover 5 and the outer wall of the upper end of the first tube 52 being rotatably connected to the center of the top of the cover 5, and the first tube 52 being rotatably connected to the partition plate 51; a second tube 53 located inside the first tube 52 and the outer wall of the second tube 53 being slidably connected to the inner wall of the first tube 52; and a plurality of third tubes 54 circumferentially arranged inside the cover 5, the upper end of the third tube 54 penetrating the top of the cover 5 and the outer wall of the upper end of the third tube 54 being rotatably connected to the top of the cover 5, and the third tube 54 being rotatably connected to the partition plate 51.

[0069] In one embodiment of the present invention, a second motor 55 is fixedly installed above the cover 5. The output shaft of the second motor 55 passes through the top of the cover 5 and is located inside the chamber 6. The output shaft is rotatably connected to the top of the cover 5.

[0070] In one embodiment of the present invention, the chamber 6 is provided with a first gear 61, a plurality of second gears 62, and a third gear 63; the center of the first gear 61 is fixedly installed on the outer wall of a first tube 52 located inside the chamber 6; the centers of the plurality of second gears 62 are respectively fixedly installed on the outer walls of a plurality of third tubes 54 located inside the chamber 6; the third gear 63 is fixedly installed on an output shaft located inside the chamber 6; the first gear 61 meshes with the second gears 62; the second gears 62 mesh with the third gear 63;

[0071] In one embodiment of the present invention, a plurality of through holes 521 are provided on the surface of the first tube 52, and the plurality of through holes 521 are all located below the partition plate 51.

[0072] In one embodiment of the present invention, an airbag 541 is fixedly installed below each of the three tubes 54, and an air tube 542 is rotatably connected to the top of each of the three tubes 54.

[0073] As the spraying assembly moves downward along with the second support 32 near the end of the conveyor belt 1, the cover 5 moves downward synchronously and encloses the tubular workpiece supported on the upper end of the support frame 42. The third tube 54 also moves downward synchronously and is inserted into the tubular workpiece from above. The first tube 52 also moves downward synchronously and is located at the center position above the second disc 41 (the distance between the bottom of the first tube 52 and the surface of the second disc 41 is about 5cm).

[0074] After the cover 5 completes its downward movement, the air pipe 542 is connected to the miniature air pump installed inside the cover 5. After the miniature air pump is started, gas is injected into the No. 3 tube 54 from the top of the No. 3 tube 54 through the air pipe 542, causing the airbag 541 below the No. 3 tube 54 to inflate. When the airbag 541 inflates, the surface of the airbag 541 will contact the inner wall of the tubular workpiece, causing friction between the surface of the airbag 541 and the inner wall of the tubular workpiece. When the airbag 541 is fully inflated, the surface of the airbag 541 will squeeze the inner wall of the tubular workpiece, thereby increasing the friction between the surface of the airbag 541 and the inner wall of the tubular workpiece.

[0075] When the airbag 541 is fully inflated, the second motor 55 is energized, which drives the third gear 63 to rotate. This causes the third gear 63 and the second gear 62 to mesh, thereby causing the third tube 54 to rotate relative to the cover 5. Since there is friction between the surface of the airbag 541 and the inner wall of the tubular workpiece, and the tubular workpiece supported on the upper end of the support frame 42 can rotate relative to the conveyor belt 1, the rotating third tube 54 will drive the tubular workpiece to rotate on the conveyor belt 1.

[0076] Similarly, because the cover 5 has a horizontal displacement during downward rotation, the diameters of the third tube 54 and the initial airbag 541 are both smaller than the inner diameter of the tubular workpiece, and the gap between the tubular workpieces is large enough. This way, when the cover 5 rotates downward, the third tube 54 and the initial airbag 541 can be smoothly embedded in the tubular workpiece, and the first tube 52 can be smoothly embedded in the center position above the second disc 41, located in the gap between the tubular workpieces. The distance difference between the outer wall of the third tube 54 and the initial airbag 541 and the inner wall of the tubular workpiece can effectively compensate for the horizontal displacement of the cover 5, and prevent the third tube 54 and the initial airbag 541 from being unable to be smoothly embedded in the tubular workpiece during downward rotation of the cover 5.

[0077] In addition, by rotatably connecting the air tube 542 to the top of the third tube 54, the third tube 54 can rotate inside the cover 5.

[0078] While the tubular workpiece rotates, a pipe is rotatably connected to the top of tube 53. A liquid pump is fixedly installed at the other end of the pipe and placed inside a storage tank. Powering the pump draws paint from the storage tank into the pipe, replenishing the paint inside tube 53. The storage tank can be small, directly mounted on top of the cover 5, and moves synchronously with it. Alternatively, it can be large, with the pipe designed as a flexible hose. The storage tank is mounted on top of bracket 31 to prevent the pipe from tangling or being damaged during material transport. The paint entering tube 53 falls to the bottom of tube 52. Then, the staff pulls the pipe outward relative to the cover 5, which causes the second pipe 53 to be pulled upward. After the second pipe 53 completes its upward movement, the paint inside the second pipe 53 will enter the first pipe 52. At the same time, the outer wall of the second pipe 53 will lose its function of blocking the through hole 521. Since the paint is continuously poured in, the paint that enters the first pipe 52 will be squeezed and sprayed out of the first pipe 52 through multiple through holes 521. This allows multiple tubular workpieces supported on the support frame 42 to be sprayed. Since all the tubular workpieces are rotating at this time, multiple tubular workpieces can be sprayed at multiple angles at the same time during spraying.

[0079] With multiple through holes 521 located below the partition plate 51, paint is prevented from entering the cavity 6, thus preventing the gears from meshing and moving.

[0080] By hinged to the end of the second support 32 near the conveyor belt 1, the cover 5 can always remain vertical relative to the tubular workpiece when it moves up and down with the second support 32, thus avoiding the phenomenon that the cover 5 will bump into the tubular workpiece when it moves up and down.

[0081] When the diameter of the tubular workpiece is different, the staff only needs to insert the tubular workpieces of different diameters into the upper end of the support frame 42 to spray the tubular workpieces of different diameters without stopping the entire production line to change them, thereby reducing the labor intensity of the staff.

[0082] When the lengths of the tubular workpieces are different, the operator only needs to pull or push the pipe to control the vertical distance of the second pipe 53 inside the first pipe 52, thereby controlling the through hole 521 on the outer wall of the second pipe 53 that can be blocked. For example, when the tubular workpiece is small, the operator pushes the pipe to move the second pipe 53 downward inside the first pipe 52, and the through hole 521 above the first pipe 52 will be blocked by the outer wall of the second pipe 53, preventing paint from being sprayed out. Conversely, the through hole 521 below the first pipe 52 is not blocked by the outer wall of the second pipe 53, so paint can be sprayed onto the outside of the first pipe 52. This allows for spraying according to the length of the tubular workpiece, reducing paint waste.

[0083] The tubular workpiece is enclosed in the cover 5 and sprayed inside the cover 5, so that the tubular workpiece can be sprayed in a closed environment, thereby reducing the phenomenon of paint splashing everywhere during spraying.

[0084] In one embodiment of the present invention, a drain outlet 411 is provided on one side of the second disc 41;

[0085] During the spraying process, the drain outlet 411 is closed, and the paint on the surface of the workpiece will drip into the second disc 41. After the spraying is completed, the drain outlet 411 is opened to let out the paint, and the staff collects it from the outside.

[0086] In one embodiment of the present invention, the airbag 541 is made of hydrogenated nitrile rubber (HNBR) material;

[0087] Hydrogenated nitrile rubber (HNBR) has excellent chemical corrosion resistance and high compression set resistance. Simultaneously, hydrogenated nitrile rubber also possesses high strength, high tear resistance, and excellent abrasion resistance. Therefore, by making airbag 541 from hydrogenated nitrile rubber (HNBR), airbag 541 can be made resistant to chemical corrosion and possess compression set resistance, thus ensuring the service life of airbag 541.

[0088] In one embodiment of the present invention, the second bracket 32, the support assembly and the spraying assembly form a working unit, and multiple working units are distributed around the upper circumference of the first disc 3.

[0089] By forming a working unit from the second bracket 32, the support assembly, and the spraying assembly, and with multiple working units distributed around the circumference above the first disc 3, multiple working units can alternately complete the spraying of the tubular workpiece transported by the conveyor belt 1. This avoids the phenomenon that the tubular workpiece needs to stop on the production line to complete the spraying. At the same time, by setting the conveyor belt 1 as a ring, and by automatically extracting the tubular workpiece after processing by a robot arm to enter the next process, the continuity of the spraying system is improved, thereby improving the production efficiency of the spraying system.

[0090] Working principle:

[0091] By vertically placing multiple tubular workpieces on the support assembly, the support assembly can support multiple tubular workpieces simultaneously. Then, the first motor 21 is energized, causing the output end of the first motor 21 to drive the first disc 3 to rotate relative to the chassis 2 (i.e., the working plane, such as the factory floor). The rotating first disc 3 will drive the first bracket 31, the second bracket 32 ​​and the spraying assembly to rotate synchronously. Since the conveyor belt 1 is in a non-working state (i.e., a stopped state) at this time, the spraying assembly will rotate relative to the conveyor belt 1.

[0092] When the spraying assembly rotates close to the support assembly, the electric telescopic rod 312 is energized, causing its output end to move downward relative to the first bracket 31. This pulls the end of the second bracket 32 ​​near the electric telescopic rod 312 downward relative to the first bracket 31. Then, the second bracket 32 ​​is rotated and mounted above the first disc 3 via the third bracket 33, causing the other end of the second bracket 32 ​​to move upward. This causes the spraying assembly to move upward relative to the conveyor belt 1. Once the spraying assembly has moved upward, it will continue to rotate with the first disc 3.

[0093] When the spraying assembly rotates to the top of the support assembly (i.e., above the tubular workpiece), the output end of the electric telescopic rod 312 is moved upward relative to the first bracket 31 by controlling the electric telescopic rod 312, which in turn causes the spraying assembly to move downward. The downward-moving spraying assembly will cover all the tubular workpieces on the support assembly inside the spraying assembly. After the spraying assembly has completed its downward movement, it will start to spray all the tubular workpieces inside it simultaneously from multiple angles.

[0094] By providing a sliding groove inside the end of the second bracket 32 ​​near the first bracket 31, the telescopic end of the electric telescopic rod 312 is located inside the sliding groove and can rotate with the inside of the sliding groove and slide along the inner wall of the sliding groove. In this way, when the telescopic end of the electric telescopic rod 312 drives the second bracket 32 ​​to move vertically up and down, the arc motion trajectory of the second bracket 32 ​​can be prevented from conflicting with the vertical motion trajectory of the electric telescopic rod 312.

[0095] By controlling the rotation direction and speed of conveyor belt 1 and the rotation direction and speed of disk 3 to the same speed, the spraying component is aligned with the rotation direction and speed of conveyor belt 1. Therefore, the tubular workpiece will be continuously sprayed by the spraying component during transportation. Then, multiple spraying components will alternately spray multiple workpieces, thereby avoiding the need for the tubular workpiece to stop on the production line to complete the spraying.

[0096] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
