The oil spray gun 2 is fixedly mounted on the oiling robot 1, and is provided with an oil nozzle 21 for spraying oil. The oil supply system provides the oil spray gun 2 with oil of a set pressure. The oiling robot 1 can drive the oil spray gun 2 to move within a three-dimensional space within a set range, so that the oil spray nozzle 21 on the oil spray gun 2 is aimed at the part of the product that needs to be oiled for spraying oil. The controller controls the movement of the oiling robot 1 and controls the oil supply system to provide the oil spray gun 2 with oil quantity and oil spraying time.

[0026] When oiling a product, first fix and position the product to be oiled on the product positioning carrier 3, and expose the part to be oiled, and fix the oil spray gun 2 on the moving end of the oiling manipulator 1, and the oiling manipulator 1 moves the oil spray gun 2, so that the oil nozzle 21 of the oil spray gun 2 is directly opposite to or away from the different oiling parts on the product. After the oil nozzle 21 of the oil spray gun 2 is directly opposite to the part to be oiled on the product, the oil supply system provides oil to the oil spray gun 2, and the oil is sprayed from the oil nozzle 21 of the oil spray gun 2. The oil pressure, amount and time of the oil spray are all controlled by the controller in the form of mist or oil droplets, so that the oil is finally sprayed on the surface of the product where oil is needed according to the design requirements, forming a uniform oiling effect. After the oiling is completed, the oiling robot 1 returns to a certain distance away from the product positioning carrier 3 with the oil spray gun 2, and then removes the product from the product positioning carrier 3 and replaces it with the next product that needs oiling. The above device realizes automatic oiling of the product and avoids manual oiling operation. The oil amount on the product is consistent, the oiling position is accurate, and the oiling is uniform.

[0027] The oil supply system includes an oil tank, an oil pump, an injection valve and an oil supply pipeline. The oil tank is connected to the oil inlet of the oil spray gun 2 through the oil supply pipeline. The oil pump can inject the oil in the oil tank into the oil spray gun 2 through the oil supply pipeline. The oil spray valve is installed inside the oil spray gun 2. The controller and the oil spray valve are electrically connected and communicated through the control circuit. The controller can control the opening, closing and opening size of the oil spray valve and thus control the start, stop and injection amount of the oil spray nozzle 21. After the oil supply system is started, the oil pump injects the oil in the oil tank into the oil spray gun 2. The oil pressure entering the oil spray gun 2 can be adjusted by adjusting the oil pump supply pressure. The oil flow rate and oil supply time entering the oil spray gun 2 are controlled by the oil spray valve.

[0028] The oil supply system also includes a protective pipe sleeve, and the control circuit of the oil supply pipeline and the oil injection valve are both passed through the protective pipe sleeve. An oil gun bracket 11 is fixedly installed on the moving end of the oiling robot 1, and the oil spray gun 2 is fixedly installed on the oil gun bracket 11.

When in use, the position of the positioning block 33 on the product support plate 32 can be adjusted to adapt to the positioning of products of different specifications. Each positioning block 33 preferably forms an inclined chamfered surface at the upper end facing one side of the product, so that the product is quickly loaded into the positioning space surrounded by each positioning block 33. Finally, the pressing block 34 is driven by the clamping drive device to clamp the surface of the product that needs to be oiled. The structure can be designed with a hollow part between the pressing block 34 and the positioning block 33 according to the oiling needs, so as to facilitate the insertion of the oil spray nozzle 21 for oil spraying.

The controller controls the cylinder 35 to start and stop. The piston rod of the cylinder 35 is extended and retracted to drive the lever 36 to swing with the support rod 37 as a fulcrum. This structure can use the principle of the lever 36 to stably clamp and position the product. In addition to the above structure, the clamping drive device can also directly connect the piston rod of the cylinder 35 to the pressure block 34 to achieve product clamping and loosening, or use a quick clamping mechanism to achieve product clamping and positioning. These are equivalent replacement structures that can be easily thought of by technicians in this field based on this application and belong to the protection scope of this application.

[0033] The clamping drive device also includes a clamping limit block 38, and the side wall of the clamping limit block 38 is provided with at least one elongated mounting hole extending in the up-down direction. At least two locking screws are inserted in the elongated mounting hole so as to slide up and down. The locking screws can be threadedly connected to the side wall of the support rod 37. The clamping limit block 38 can be tightly clamped between the locking screw head and the side wall of the support rod 37 to achieve fixed positioning. The upper end of the clamping limit block 38 is provided with a U-shaped opening groove, and the lower side surface of one end of the lever 36 connected to the clamping block 34 stops on the bottom surface of the U-shaped opening groove at the upper end of the clamping limit block 38, and the side wall of the lever 36 can stop between the two side walls of the U-shaped opening groove.

The controller controls the start and stop of the horizontal driving device 51.

[0037] The product positioning carrier 3 slides back and forth on the linear guide rail 6 to reach the oiling station and the loading and unloading station, avoiding the oil nozzle 21 from hitting during loading and unloading, thus facilitating loading and unloading and accurate oiling.

[0038] The oiling platform 5 is also fixedly provided with a front limit block 7 and a rear limit block 8, which are respectively located at the two ends of the extension direction of the linear track.

When the product positioning carrier 3 slides back and forth on the linear guide rail 6 to reach the oiling station and the loading and unloading station, the side wall of the product positioning carrier 3 first contacts the front buffer 71 and the rear buffer 81 to slow down, and finally contacts the front hard limit 72 and the rear hard limit 82 for precise positioning to ensure its accurate oiling position. When the product positioning carrier 3 reaches the oiling station or the loading and unloading station, the controller receives the signals from the front sensor 73 and the rear sensor 83, and controls the oiling robot 1, the oil supply system and the clamping drive device on the product positioning carrier 3 to work, thereby realizing intelligent oiling and loading and unloading.

[0039] A protective cover 9 and an oiling partition 10 are also fixedly installed on the oiling platform 5.
