Description

Technical Field

[0001] The utility model relates to the field of robot automatic painting, in particular to a stacked atomizer coating device. Background Art

[0002] The atomizer is installed on the wrist of the spray robot. It relies on the high-speed rotation of the bell in front of the atomizer to atomize the paint. Usually, a certain voltage of static electricity is loaded on the bell. After the paint particles are charged with static electricity, the electrostatic coating effect can be more effectively utilized to improve the paint coating rate. There is a shaping air ring at the rear end of the bell, which has multiple small air outlets. The compressed air ejected from the air holes can more effectively blow the paint mist particles to the workpiece and control the paint mist to spray in an appropriate shape. The atomizer body usually includes a plastic shell. Due to the scattering of paint particles, the movement of the robot wrist, and the electrostatic effect, the plastic shell of the atomizer will be attached with paint particles during the spraying process, forming contamination on the surface of the atomizer. After a period of spraying, if the atomizer shell is not cleaned, the paint adsorbed on the atomizer shell may fall off from the shell to the workpiece during the spraying process, resulting in product defects such as mottled pollution and paint dripping. Therefore, the atomizer must be cleaned periodically during the actual spraying operation.

[0003] There are two common methods for cleaning the atomizer:

[0004] Method 1: Manual cleaning, that is, the spraying operation is stopped after a period of time, and personnel enter the spray room and manually clean the atomizer with a rag or other cleaning materials. However, this requires stopping the spraying operation, and workers generally need to clear the sprayed workpieces in the spray room (the spray room of an automobile factory usually needs to stop the line 2-4 times / shift, and the cleaning time of each shift depends on the degree of contamination of the atomizer). This will reduce the spraying time and lose production capacity; in addition, during the manual cleaning of the atomizer, the air conditioning / circulating air / circulating water of the spray room are all in the open state, and the baking room supporting the spraying is also in the working state, so energy is wasted.

[0005] Method 2: Equipped with a dedicated atomizer cleaning machine. The cleaning machine can be between workpieces and during the short stop interval of the spraying operation. The robot can carry the atomizer into the cleaning machine. The cleaning machine sprays out solvents and rinses the paint adsorbed on the surface of the atomizer, so there is no need to stop the spraying work for cleaning. Because the atomizer cleaning machine uses the interval between spraying operations instead of stopping the line for cleaning, the production efficiency is greatly improved compared to manual cleaning. The solvent used in the atomizer cleaning machine generally contains VOC liquid materials, and during the cleaning process, a stream of compressed air needs to be sprayed downward to form a vacuum negative pressure area to prevent the paint mist and solvent from washing back during the atomizer cleaning process. After completing the cleaning work, use compressed air to blow / dry the atomizer to keep the atomizer clean and dry. The use of a cleaning machine must use VOC solvents and consume a lot of compressed air, which increases environmental pollution. Since the cleaning solvent usually contains VOC components, it will cause problems with VOC processing costs and compressed air energy consumption. Utility Model Content

[0037] The stacked atomizer coating device of the utility model is described in detail below with reference to the accompanying drawings of the specification.

[0038] Embodiment 1

[0039] See also Figure 1-5The utility model provides a stacked atomizer coating device, which structure includes a frame 1, a workbench 2, a material transfer mechanism 3, a silo mechanism 5, a sensor assembly 6 and a coating mechanism 7. The workbench 2 is fixedly connected to the frame 1, a silo mechanism 5 is provided on one side of the workbench 2, and a coating mechanism 7 is provided on the other side of the workbench 2. The sensor assembly 6 is provided on one side of the silo mechanism 5 and connected to the workbench 2. The material transfer mechanism 3 is slidably connected to the frame 1 through a slide rail 4. Multiple protective films 11 can be stacked in the silo mechanism 5, and the suction cup of the material transfer mechanism 3 absorbs one protective film at a time and moves it to the coating mechanism 7, and the coating mechanism 7 is used to coat the head of the atomizer 8 for protection.

[0040] The sensor assembly 6 includes a lifting sensor 61, a refilling sensor 62 and a mounting rod. When the lifting cylinder 55 of the silo mechanism 5 rises, the lifting sensor 61 detects the stacked protective film and sends a signal, and the cylinder lifting stops. When the cylinder is in a retracted state, the refilling signal control of the refilling sensor 62 is not triggered, and refilling is required at this time.

[0041] like Figure 2 , Figure 4 As shown, the silo mechanism 5 includes a lifting plate 51, a support rod 52, an arc-shaped hole 53, a nut 54 and a lifting cylinder 55. The lower end of the support rod 52 is connected to the workbench 2 through the nut 54. The lifting plate 51 and the support rod 52 are movably sleeved. The lifting cylinder 55 is arranged on the workbench 2. The telescopic end of the lifting cylinder 55 is connected to the lifting plate 51. The middle part of the lifting plate 51 is provided with a protective film placement hole. The corresponding positions on the lifting plate and the workbench are provided with arc-shaped holes 53. The support rod is sleeved with the arc-shaped hole. The position of the support rod 52 can be adjusted by the nut 54 to meet different usage requirements. The top edge of the protective film 11 is provided with a hard folded edge. When the protective film 11 is placed in the inner hole of the lifting plate 51, the hard folded edge on the top of the protective film is limited by three support rods 52. The telescopic control of the lifting cylinder 55 controls the lifting plate 51 to move up and down along the support rods 52, and at the same time drives the stacked protective films 11 to move up and down. When the top protective film 11 is sucked away by the material moving mechanism 3, the lifting cylinder 55 pushes the lifting plate 51 to move upward, and the lifting plate 51 pushes the stacked protective films 11 to move upward. After the material moving mechanism 3 is reset, it adsorbs the next protective film again, thereby realizing the repeated material moving action of the material moving mechanism 3.

[0042] like Figure 5As shown, the material moving mechanism 3 includes a slider 31, a cylinder 32, a shaping tool 33 and a suction cup 34. The slider 31 is slidably connected to the slide rail 4, and the cylinder 32 is connected to the slider 31 to realize the lateral movement of the material moving mechanism 3. The shaping tool 33 is connected to the telescopic end of the cylinder, and the up and down movement of the material moving mechanism is realized by setting the cylinder. The extension and contraction of the cylinder drives the shaping tool to move downward to realize the function of adsorbing the protective film. The upper edge of the shaping tool 33 is evenly provided with a plurality of suction cups 34 that adsorb the folded edge of the protective film. The hard folded edge around the top of the protective film is adsorbed by the suction cup 34, so that the protective film 11 is moved to the top of the coating mechanism 7, and then the shaping tool adsorbed with the protective film is placed in the coating mechanism by extending the cylinder.

[0043] Since the size of the shaping tool 33 is larger than the protective film, the protective film will be expanded after the plastic tool is used to shape the protective film. At this time, the protective film is in an expanded state.

[0044] like Figure 3 , Figure 4 As shown, the coating mechanism 7 includes a positioning plate 71, a positioning rod 72, a suction cup mounting seat 73, a suction cup 2 74, a linear bearing 75 and a compression spring 76. The lower end of the positioning rod 72 is connected to the workbench 2, and the upper end of the positioning rod 72 is connected to the positioning plate 71 through a compression spring 76 and a linear bearing 75. Two compression springs 76 are provided, and the two compression springs are respectively placed above and below the positioning plate 71. The linear bearing 75 is fixed on the positioning plate 71. The linear bearing and the positioning plate can float up and down on the positioning rod. The compression spring below the positioning plate is positioned by the positioning plate and the shoulder on the positioning rod. The spring above the positioning plate is positioned with the linear bearing through a flat washer. The upper end of the positioning rod is provided with a threaded hole, and the flat washer is fixed to the positioning rod by a screw. By arranging compression springs at the upper and lower parts of the positioning plate, the positioning plate can float up and down to prevent rigid collision after the protective film or atomizer is inserted. A suction cup mounting seat 73 is disposed on the upper portion of the positioning rod 72 , and a suction cup 74 is disposed on the inner side of the suction cup mounting seat for adsorbing to the outer wall of the protective film 11 .

[0045] The suction cup mounting seat 73 is provided with a slide groove, and the suction cup 2 74 is slidably connected in the slide groove. The suction cup slides along the slide groove to adjust the position of the suction cup to meet different usage requirements.

[0046] The protective film 11 is stacked and placed in the hopper mechanism 5, and then the cylinder 32 of the material moving mechanism 3 controls the shaping tooling 33 to move down to the top layer of the protective film 11. At this time, the protective film remains in an expanded state under the action of the shaping tooling, and the suction cup 1 34 begins to work to adsorb the top layer of the protective film. The cylinder of the material moving mechanism 3 retracts, driving the shaping tooling 33 and the adsorbed protective film to move upward together until they are completely separated from the hopper mechanism 5. Then the material moving mechanism 3 slides along the slide rail 4 to the top of the coating mechanism 7, and the cylinder rod of the cylinder 32 extends downward, while driving the shaping tooling 33 and the adsorbed protective film to move downward to the inner hole of the positioning plate of the coating mechanism. Since the coating mechanism 7 is provided with multiple suction cups 2 74, the suction cups 2 74 can adsorb the outer wall of the protective film from multiple positions, thereby fixing the protective film. Then the cylinder of the material moving mechanism 3 retracts, while driving the shaping tooling 33 to move upward, thereby separating the shaping tooling from the protective film, and the material moving mechanism 3 is reset to wait for the next material moving. At the same time, the atomizer 8 is placed in the protective film in the coating mechanism 7, and then the suction cup 2 74 is controlled to fail. At this time, the protective film changes from an expanded state to a contracted state, so that the protective film is tightly sheathed on the atomizer head, completing the atomizer coating work.

[0047] A protective film placement hole is provided in the middle of the positioning plate 71. In order to make the protective film and the side wall of the atomizer head wrap more tightly, a plurality of auxiliary blowing holes 77 are evenly provided around the protective film placement hole. The auxiliary blowing holes 77 are connected to the air pipe at the bottom, and the air pipe is connected to the air source through a pipeline and a valve. Blowing air through the auxiliary holes acts on the hard folding edge of the protective film to improve the tightness of the combination of the protective film and the side wall of the atomizer.

[0048] Embodiment 2

[0049] A stacked atomizer coating device, which structure includes a frame 1, a workbench 2, a material transfer mechanism 3, a silo mechanism 5, a sensor assembly 6, a coating mechanism 7 and a film removal mechanism. The workbench is fixedly connected to the frame, a silo mechanism is provided on one side of the workbench, and a coating mechanism is provided on the other side of the workbench. The sensor assembly is provided on one side of the silo mechanism and connected to the workbench, and the material transfer mechanism is slidably connected to the frame via a slide rail. Multiple protective films can be stacked in the silo mechanism, and the suction cup of the material transfer mechanism absorbs one protective film at a time and moves it to the coating mechanism, and the coating mechanism is used to protect the head of the atomizer. Figure 6 , Figure 7 As shown, a film removal mechanism 9 is provided on one side of the workbench 2, and a waste box 10 for easy storage is provided below the film removal mechanism 9. The film removal mechanism 9 includes a fixing plate 91 and an anti-collision plate 92. The fixing plate 91 and the anti-collision plate 92 are both U-shaped, and the diameter of the U-shaped opening is larger than the diameter of the atomizer head and smaller than the diameter of the hard folded edge of the protective film. The anti-collision plate 92 is screwed to the bottom of the fixing plate, and the anti-collision plate is made of non-metallic material to prevent the fixing plate from colliding with the atomizer and being damaged.

[0050] The protective film 11 is stacked and placed in the hopper mechanism 5, and then the cylinder 32 of the material moving mechanism 3 controls the shaping tooling 33 to move down to the top layer of the protective film 11. At this time, the protective film remains in an expanded state under the action of the shaping tooling, and the suction cup 1 34 begins to work to adsorb the top layer of the protective film. The cylinder of the material moving mechanism 3 retracts, driving the shaping tooling 33 and the adsorbed protective film to move upward together until they are completely separated from the hopper mechanism 5. Then the material moving mechanism 3 slides along the slide rail 4 to the top of the coating mechanism 7, and the cylinder rod of the cylinder 32 extends downward, while driving the shaping tooling 33 and the adsorbed protective film to move downward to the inner hole of the positioning plate of the coating mechanism. Since the coating mechanism 7 is provided with multiple suction cups 2 74, the suction cups 2 74 can adsorb the outer wall of the protective film from multiple positions, thereby fixing the protective film. Then the cylinder of the material moving mechanism 3 retracts, while driving the shaping tooling 33 to move upward, thereby separating the shaping tooling from the protective film, and the material moving mechanism 3 is reset to wait for the next material moving. At the same time, the atomizer 8 is placed in the protective film in the coating mechanism 7, and then the suction cup 2 74 is controlled to fail. At this time, the protective film changes from an expanded state to a contracted state, so that the protective film is tightly sheathed on the head of the atomizer, completing the coating work of the atomizer. When the contaminated atomizer needs to be re-coated with a protective film, the dirty protective film must be removed first. The robot enters the film removal mechanism 9 with the atomizer, and clamps the hard edge of the protective film through the semicircular openings of the fixed plate 91 and the anti-collision plate 92 of the film removal mechanism. Then the atomizer moves upward. Since the protective film cannot move upward with the atomizer due to the limitation of the anti-collision plate, it is separated from the atomizer, and the separated waste falls into the waste box 10. At this time, the atomizer is in a clean state and can enter the coating mechanism to cover a new protective film.

[0051] The atomizer coating device of the utility model realizes automatic installation of the protective film on the atomizer head by arranging the material moving mechanism, the material bin mechanism and the coating mechanism, and does not use solvent materials to wash the surface of the atomizer, because the use of raw material solvents containing VOCs is reduced, environmental pollution is reduced, the treatment of hazardous waste is reduced, and the use of compressed air is reduced, thereby saving energy.

[0052] The above description is only used to illustrate some principles of the utility model. This specification is not intended to limit the utility model to the specific structure and application scope shown and described. Therefore, all corresponding modifications and equivalents that may be used belong to the patent scope applied for the utility model.

[0053] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
