Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a painting robot for automobile production with cleaning function. Background Technology

[0002] Automotive painting robots are the core intelligent equipment in modern automotive painting workshops. They are typically multi-jointed robotic arms with extremely high mobility and repeatability. Their core function is to replace manual labor and automatically and evenly apply a high-quality "coat" to the car body. Through advanced electrostatic rotary cups or spray guns mounted at the end, under precise program control, they can perfectly reproduce the painting trajectory of every complex car body contour, ensuring uniform paint film thickness, no color difference, and no drips.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Spraying Device for Robotic Production with Cleaning Function," patent application number: 202121890871.7. It includes a workbench, a vertical plate, a support arm, and a spray nozzle. The vertical plate is fixedly connected to one side of the top of the workbench, and the support arm is fixedly connected to the top of one side of the vertical plate. A spray nozzle is fixedly connected to one end of the support arm. An auxiliary mechanism is provided at the bottom of the spray nozzle. The auxiliary mechanism includes a slot, which is located on the top of the workbench. A filter plate is provided inside the slot, and the filter plate is slidably connected to the workbench. The beneficial effects of this utility model are... The result is that the cleaning function of the robot production spraying device sprays excess paint into the liquid inside the empty tank when the spray nozzle processes the robot parts supported on the top of the support plate. This helps to keep the workbench surface clean, reduces the resource input required to clean the workbench surface, lowers the cost of robot production, and improves the work efficiency of the workers. In contrast, the spraying robots mentioned above clean the paint by directly spraying excess paint into the empty tank. As the nozzles are constantly spraying, their surfaces become contaminated with a lot of paint residue, which can lead to paint color confusion in the next spraying and affect the quality of the spraying.

[0004] Therefore, it is necessary to redesign and modify the spraying robot to effectively prevent the phenomenon of paint residue at its nozzles that is difficult to clean. Utility Model Content

A water pump 6 is fixedly connected to the top of the water tank 5. The input end of the water pump 6 is connected to a suction pipe 7. The side of the suction pipe 7 away from the water pump 6 extends into the interior of the water tank 5. The top of the outer side of the water tank 5 is connected to a water filling pipe 8. The output end of the water pump 6 is connected to a corrugated spray pipe 9. A support rod 10 is fixedly connected to the bottom of the corrugated spray pipe 9. The bottom of the support rod 10 is fixedly connected to the spraying assembly 3.

[0032] refer to Figure 1 , Figure 2 and Figure 3 A water collection and purification mechanism 11 is fixedly connected to the front of the base 1. The water collection and purification mechanism 11 includes a water collection box 12. An irregularly shaped filter plate 13 is provided inside the water collection box 12. A lower rod 14 is fixedly connected to the left side of the bottom of the irregularly shaped filter plate 13. Fixing plates 15 are fixedly connected to the front and rear sides of the left side of the water collection box 12. A spring 16 is fixedly connected to the inner side of the fixing plate 15. A stop plate 17 is fixedly connected to the inner side of the spring 16. The right side of the stop plate 17 is slidably connected to the water collection box 12. A locking plate 18 is fixedly connected to the inner side of the stop plate 17. The inner side of the locking plate 18 extends through the interior of the lower rod 14.

[0033] As a technical optimization of this utility model, the water purification mechanism 11 can be set up to recycle and purify the water after cleaning, thus saving a certain amount of water resources.

[0034] refer to Figure 3 The lower rod 14 has slots 19 on both the front and back, and the inner side of the card plate 18 is engaged with the inside of the slots 19.

[0035] As a technical optimization of this utility model, the slot 19 allows the card plate 18 to be more securely engaged inside the lower rod 14, preventing it from falling off.

[0036] refer to Figure 3 The water receiving box 12 has grooves 20 on both the front and rear sides on the left side, and the right side of the abutment 17 is slidably connected to the inside of the grooves 20.

[0037] As a technical optimization of this utility model, the sliding groove 20 enables the abutment 17 to slide more smoothly inside the water receiving box 12, reducing the friction between the abutment 17 and the water receiving box 12, extending the service life of the abutment 17, and at the same time limiting the position of the abutment 17.

[0038] refer to Figure 2 A guide plate 21 is fixedly connected to the right side of the top of the water receiving box 12. The guide plate 21 is used in conjunction with the water receiving box 12.

[0039] As a technical optimization of this utility model, the guide plate 21 can guide the falling cleaning water and prevent it from splashing to the outside.

[0040] refer to Figure 2 The corrugated water spray pipe 9 is connected to a concentrator 22 on the side away from the water pump 6. The concentrator 22 is used in conjunction with the corrugated water spray pipe 9.

[0041] As a technical optimization of this utility model, the water flow can be restricted by the setting of the centralized head 22, thereby increasing the cleaning effect.

[0042] The working principle and usage process of this utility model are as follows: First, the user injects cleaning water or diluent into the tanks through the water inlet pipes 8 on the top of the two water tanks 5. When it is necessary to clean the nozzles of the spraying component 3, the two water pumps 6 are started. The water pumps 6 draw clean water from the water tanks 5 through the suction pipes 7. After being pressurized by the water pumps 6, the clean water is delivered through the corrugated spray pipes 9. The water flow finally sprays out from the concentrator 22 at the end of the corrugated spray pipes 9, aiming at the nozzles of the moving spraying component 3 to rinse away the residual paint, achieving the effect of conveniently cleaning the paint residue at the nozzles. Then, the wastewater generated during rinsing drips downwards. Since the water receiving box 12 is located on the front of the base 1 and has a guide plate 21 on its top right side, the wastewater will be effectively guided and collected into the water receiving box 12. The wastewater flowing into the water receiving box 12 is first filtered through the irregularly shaped filter plate 13. The irregularly shaped filter plate 13 intercepts impurities such as paint debris and solid particles, achieving the effect of purifying the wastewater.

[0043] In summary, this automotive painting robot with cleaning function changes the traditional problem of inconvenient cleaning of residual paint at the nozzle. By using a corrugated water spray pipe 9 to spray cleaning water onto the nozzle of the painting component 3, residual paint can be easily cleaned, thus improving the quality of subsequent painting.
