The paint spraying robot 1 has the advantages of flexibility, force control, and precise trajectory path, and can achieve multi-angle movement, thereby driving the spray gun 2 to move well, ensuring the uniformity of the paint spraying of the spray gun 2, and making the paint quality of the outer surface of the sole 8 highly consistent, which can greatly reduce the unqualified rate.

[0031] The rotating placement platform 3 is provided with loading and unloading stations located outside the paint spraying box 4 and a painting station located inside the paint spraying box 4 in sequence around the rotating placement platform 3 along its rotation direction. Through the combined use of the loading and unloading stations and the painting station, double-station operation can be realized. In this way, the loading and unloading stations perform manual loading and unloading operations, and the painting station performs painting operations. At the same time, by arranging the loading and unloading stations outside the paint spraying box 4, the loading and unloading operations of the operators can be convenient. By arranging the painting station inside the paint spraying box 4, the pollutants generated by the painting can be treated in time to avoid spreading to the working environment. The rotating placement platform 3 is used to place the sole 8 and drive the sole 8 to rotate and switch between the loading and unloading stations and the painting stations, including loading, painting, and unloading, and so on. The continuous painting production operation of the sole 8 can be realized. Specifically, the rotating placement platform 3 includes a workbench 31, a rotating frame 32, a first intermittent rotation drive mechanism 33 and a placement fixture 34.

[0032] The rotating frame 32 is a rectangular frame structure as a whole. The rotating frame 32 is rotatably mounted on the upper end of the workbench 31. Accordingly, the rotating frame 32 is fixedly mounted on the upper end of the rotating cylinder 351. The rotating cylinder 351 is rotatably mounted on the upper end of the workbench 31 through a slewing bearing 352. Accordingly, the rotating cylinder 351 includes a cylinder body and a support plate fixedly arranged on the upper end of the cylinder body. In addition, the paint spraying robot 1 is fixedly mounted on the upper end of the fixed seat 353. Accordingly, the fixed seat 353 includes a fixed shaft and a fixed The mounting plate is arranged at the upper end of the fixed shaft, and the fixed seat 353 is fixedly installed at the upper end of the workbench 31 and is located in the rotating cylinder 351. In a specific embodiment, the central axis of the fixed shaft can be set to coincide with the central axis of the cylinder, and the height of the mounting plate is made higher than the height of the support plate, so that the installation position of the paint spraying robot 1 is located at the rotation center of the rotating frame 32. At the same time, it can also well ensure that the paint spraying robot 1 will not interfere with the normal rotation of the rotating frame 32.

[0033] The first intermittent rotation drive mechanism 33 is arranged on the workbench 31 and is used to drive the rotating frame 32 to intermittently rotate 180 degrees to better cooperate with the double-station operation of the loading and unloading station and the painting station. Accordingly, the first intermittent rotation drive mechanism 33 includes a first servo motor 331, and the first servo motor 331 is fixedly installed on the inner top surface of the workbench 31. The motor shaft of the first servo motor 331 passes through the upper end surface of the workbench 31 and is fixedly installed with a driving gear 332. The driving gear 332 is meshed with the outer gear ring 333 of the slewing support 352 for transmission. The first servo motor 331 is electrically connected to the control system 92.

The sole 8 can be detachably arranged in the placement fixture 34, and the placement fixture 34 includes a bottom clamp seat 341, a top pressure cover 342, a rotating seat 343 and a second intermittent rotation drive mechanism 344.

[0035] The bottom clamp seat 341 is used to place the detachable sole 8 and shield the bottom surface of the sole 8, effectively preventing paint from being sprayed onto the bottom surface of the sole 8 during the painting process to better ensure the painting effect. The top surface of the bottom clamp seat 341 is provided with an engaging groove 3411 adapted to the bottom of the sole 8 to ensure that the sole 8 is stably placed in the bottom clamp seat 341, and can achieve stable clamping of the sole 8 during the automatic painting process. The bottom surface of the bottom clamp seat 341 is a plane to facilitate the installation of the bottom clamp seat 341. Preferably, the depth of the engaging groove 3411 is 2-4mm. Thus, while ensuring that the sole 8 can be stably placed in the engaging groove 3411, the area of ​​the outer peripheral surface of the sole 8 can be exposed to the maximum extent. In addition, the outer contour of the bottom clamp seat 341 is adapted to the outer contour of the sole 8.

[0036] The top pressure cover 342 is detachably arranged on the top surface of the sole 8 and is used to press the sole 8 by its own weight and can cover the top surface of the sole 8. The top pressure cover 342 can be conveniently removed to facilitate the easy placement of the sole 8 and effectively prevent the paint from being sprayed onto the top surface of the sole 8 during the painting process to better ensure the painting effect.

In addition, two symmetrical holding grooves 3422 are provided on the outer peripheral surface of the top pressure cover 342 to facilitate the holding and lifting of the top pressure cover 342, effectively avoiding accidental slipping and falling when taking it. In addition, the outer contour of the top pressure cover 342 is adapted to the outer contour of the sole 8.

[0037] In addition, the rotating seat 343 includes a U-shaped bottom frame 3431 , and a connecting plate 3432 is fixedly provided at the open end of the U-shaped bottom frame 3431 .

[0038] The bottom clamp seat 341 is arranged on the rotating frame 32. Specifically, the bottom clamp seat 341 is connected to the upper end of the rotating seat 343. Accordingly, the bottom clamp seat 341 is detachably connected to the rotating seat 343 through a locking mechanism 345, thereby facilitating the replacement of the bottom clamp seat 341 and the top pressure cover 342 at the same time, and replacing them with structures of different styles or sizes to adapt to the painting operation of the soles 8 of different styles or sizes. In addition, the locking mechanism 345 includes a locking stud 3451 and a locking nut 3452. At least one locking stud 3451 is fixedly provided on the bottom end surface of the bottom clamp seat 341, and at least one locking hole 3453 matched with the locking stud 3451 is provided on the connecting plate 3432. The lower end of the locking stud 3451 passes through the locking hole 3453 and is threadedly connected with the locking nut 3452. The disassembly and assembly are simple and convenient, and when locked and fixed, the stability of the installation position of the bottom clamp seat 341 can be effectively ensured. Preferably, the number of the locking stud 3451 and the locking hole 3453 are both two and they are arranged one by one.

[0039] The rotating seat 343 is rotatably installed on the rotating frame 32. Accordingly, a rotating shaft 3433 is fixedly provided at the center of the bottom end surface of the rotating seat 343. A rotating hole is provided on the rotating frame 32. The rotating shaft 3433 is rotatably installed in the rotating hole of the rotating frame 32 through a bearing, thereby facilitating the rotational connection between the bottom clamp seat 341 and the rotating frame 32.

[0040] The second intermittent rotation driving mechanism 344 is arranged on the rotating frame 32 and is used to drive the rotating seat 343 to rotate intermittently. Accordingly, the rotating seat 343 can be driven to rotate intermittently 120 degrees each time. The second intermittent rotation driving mechanism 344 includes a second servo motor 3441, a motor seat 3442 and a coupling 3443. The second servo motor 3441 is fixedly mounted on the motor seat 3442, and the motor seat 3442 is fixedly mounted on the bottom end surface of the rotating frame 32. The lower end of the rotating shaft 3433 extends downward and passes through the bottom surface of the rotating frame 32. The motor shaft of the second servo motor 3441 is transmission-connected to the lower end of the rotating shaft 3433 through the coupling 3443. The spray gun 2 sprays the sole 8 in a direction toward one side of the water curtain cabinet 5. The second servo motor 3441 is electrically connected to the control system 92 The swivel seat 343 is connected to the swivel seat 343 by controlling the second servo motor 3441 to rotate 120 degrees each time, that is, the sole 8 needs to be rotated three times so that the three different areas of the outer peripheral surface of the sole 8 are sequentially facing the spray gun 2, and at the same time, the spray gun 2 is driven to move in a direction close to parallel to the sole 8 in cooperation with the paint spraying manipulator 1, instead of driving the spray gun 2 to spray the sole 8 in a circle to complete the entire painting, so as to better ensure that the spray gun 2 always keeps spraying the sole 8 in the direction toward one side of the water curtain cabinet 5 as much as possible. In this way, while ensuring that the entire circle of the outer peripheral surface of the sole 8 is sprayed, it can better ensure that the paint mist generated during the painting can follow the direction of the painting and drift toward the water curtain cabinet 5 better, so as to further ensure the treatment effect of the water curtain cabinet 5 on the paint pollutants.

[0041] A paint spray chamber 41 is provided in the paint spray box 4, and an entrance 42 is provided on the upper front side of the paint spray box 4 to facilitate the paint spray robot 1 to drive the spray gun 2 to enter the paint spray chamber 41 from the entrance 42, and to facilitate the rotation of the rotating frame 32 and drive the placement fixture 34 together with the sole 8 to enter the paint spray chamber 41 from the entrance 42. The paint spray robot 1 and the rotating placement platform 3 are both arranged on one side of the entrance 42 outside the paint spray box 4, the water curtain cabinet 5 is arranged on the rear side of the paint spray box 4, and an exhaust gas discharge device for discharging exhaust gas is provided on the top of the paint spray box 4.

The automatic paint supply system includes a pneumatic agitator, a pneumatic lifting frame, a pneumatic diaphragm pump, a pressure regulating valve, a filter 524 and other components. Since the automatic paint supply system can use the structure in the prior art, it will not be described in detail here. In this embodiment, the number of the spray guns 2 is two, and correspondingly, the number of the automatic paint supply systems is also two, thereby realizing two different colors of painting to further enrich the appearance color or pattern effect of the sole 8. At this time, in the production process, different colors of paint can be used to repeatedly spray the outer peripheral surface of the sole 8 to obtain more colors and pattern effects.

[0043] The exhaust gas discharge device includes an exhaust pipe 61, which is fixed at the top of the paint spraying box 4 and communicates with the paint spraying chamber 41. An exhaust fan is installed on the exhaust pipe 61, and the exhaust fan is electrically connected to the control system 92. By controlling the operation of the exhaust fan, a certain suction force can be generated at the bottom of the exhaust pipe 61, that is, the top of the paint spraying box 4, so as to suck away all the exhaust gas or odor generated during painting, so as to avoid scattering and polluting the working environment, and the environmental protection is better.

[0044] The paint absorption device includes an absorption cover 71 and an absorption exhaust fan. The absorption cover 71 is provided with an absorption chamber 711 which is open upward.

Accordingly, the absorption cover 71 is arranged below the rotating frame 32 and will not interfere with the normal rotation of the rotating frame 32. It is close to the placement fixture 34 at the paint spraying station and close to the spray gun 2 to better ensure that the paint and oil splashed around the sole 8 are better absorbed. The absorption effect of paint volatile substances, thus, by controlling the operation of the absorption exhaust fan, suction can be generated at the opening of the absorption cover 71, so that the splashed paint or paint volatile substances can be absorbed in time during the painting process, effectively avoiding the splashed paint from scattering and adhering to the outer surface of the sole 8 again to cause a stain effect, so as to further effectively ensure the neatness and beauty of the color or pattern of the outer surface of the sole 8. Preferably, the longitudinal section of the absorption cover 71 is an isosceles trapezoid shape that is wide at the top and narrow at the bottom, which is beneficial to improving the absorption effect of splashed paint and paint volatile substances. In addition, a filtering device can be installed in the absorption cover 71 to achieve a certain filtering effect, and the filtering device is activated carbon cotton 5243.

The water in the overflow water trough 53 can overflow to the front side of the water curtain plate 54 and fall into the water reservoir 51, and form a downwardly flowing water curtain. When air containing pollutants such as paint mist contacts the water curtain, these pollutants can flow downward with the water, thereby realizing the separation of pollutants and gases, achieving the purpose of purifying the air, and the pollutants will be filtered and precipitated in the water reservoir 51 for subsequent waste recovery. In addition, the water curtain cabinet 5 can also adopt the structure in the prior art.

[0051] Step 2, painting, the first servo motor 331 drives the rotating frame 32 to rotate intermittently, so that the placement fixture 34 at the loading and unloading station is rotated together with the sole 8 to be painted and switched to the painting station, and then the paint spraying robot 1 can drive the spray gun 2 to move, and the spray gun 2 can spray paint on the corresponding area of ​​the outer peripheral surface of the sole 8, and during the painting process, the second servo motor 3441 can drive the rotating seat 343 to rotate, so that the sole 8 intermittently rotates and adjusts the painting position of its outer peripheral surface, so that it can better ensure that the spray gun 2 is always spraying paint on the outer peripheral surface of the sole 8 in the direction of the water curtain cabinet 5 until the entire outer peripheral surface of the sole 8 is painted;

[0052] Step 3: unloading. After the painting is completed, the first servo motor 331 continues to drive the rotating frame 32 to rotate intermittently, so that the placement fixture 34 at the painting station and the painted sole 8 are rotated and switched to the loading and unloading station. Then, the operator can remove the top pressure cover 342 and the painted sole 8 in turn.

[0053] The above steps are repeated in sequence to achieve continuous production of the sole 8.

[0054] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
