Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides two technical solutions:

[0026] First implementation: An auxiliary cleaning device based on support arm processing, including an adjusting component 1, a cleaning component 2, and a positioning component 3.

[0027] Specifically, the adjusting component 1 includes a mounting frame 11, a motor frame 12, a motor 13, a winding reel 14, a connecting wire 15, a guide wheel 16, a linear guide rail 17, a movable frame 18, and a grating sensor 19. The mounting frame 11 is fixed to the frame of the cleaning equipment, the motor frame 12 is mounted on the top of the mounting frame 11, and the motor 13 drives the winding reel 14 to wind and unwind the connecting wire 15. The connecting wire 15 is a steel wire rope or a high-strength fiber rope. After being guided by the guide wheel 16, the connecting wire 15 is connected to the cleaning component 2. The guide wheel 16 is located at both ends of the top of the mounting frame 11 and is used to change the traction direction of the connecting wire 15.

[0028] More specifically, the linear guide rail 17 is fixedly installed on the inner wall of one side of the mounting bracket 11, and the movable bracket 18 is slidably installed on the linear guide rail 17. A grating sensor 19 is installed on the movable bracket 18. There are two movable brackets 18, one is a fixed movable bracket and the other is a movable movable bracket. The bottom of the movable movable bracket is provided with a slider that cooperates with the linear guide rail 17. The linear guide rail 17 extends vertically and its length covers the cleaning area of ​​the support arm processing part. The grating sensor 19 is used to detect the distance between the cleaning part 2 and the support arm processing part to determine the cleaning height.

[0029] More specifically, the cleaning component 2 includes a movable block 21, a connecting block 22, a water inlet pipe 23, a branch pipe 24, a diversion box 25, and a nozzle 26. The movable block 21 is slidably connected to the mounting bracket 11. The connecting block 22 is fixed to the top of the movable block 21 and connected to the connecting line 15. The two ends of the water inlet pipe 23 pass through two movable blocks 21 respectively and are fixed to the movable blocks 21. Multiple branch pipes 24 are fixed at equal intervals on both sides of the water inlet pipe 23. The bottom end of the branch pipe 24 is connected to the diversion box 25. The diversion box 25 is a flat box with a flow guide baffle inside. Multiple nozzles 26 are installed on the inner side of the diversion box 25. The nozzles 26 are fan-shaped atomizing nozzles, which are evenly distributed on the inner wall of the diversion box 25 at equal intervals. The spray angle is adjustable.

[0030] The second embodiment differs from the first embodiment in that the positioning component 3 includes a mounting plate 31, a sliding groove 32, a mounting piece 33, and a position sensor 34. The mounting plate 31 is fixed to the inner wall of the lower end of the mounting frame 11. The mounting plate 31 has a sliding groove 32. The mounting piece 33 is slidably installed in the sliding groove 32. The position sensor 34 is installed on the mounting piece 33. The position sensor 34 is an infrared beam sensor or a laser rangefinder. Multiple mounting pieces 33 are provided. All mounting pieces 33 are fixed in the sliding groove 32 by bolts and can be adjusted along the sliding groove 32.

[0031] When the device is in operation, the motor 13 is started, and the motor 13 drives the winding reel 14 to wind and unwind the connecting line 15 (steel wire rope or high-strength fiber rope). The connecting line 15 changes the traction direction through the guide wheel 16 at the top of the mounting frame 11, pulling the movable block 21 of the cleaning component 2 to move up and down along the vertical direction of the mounting frame 11, ensuring that the cleaning component 2 can move up and down to the target height. The grating sensor 19 on the movable frame 18 detects the vertical distance between the cleaning component 2 and the support arm processing part in real time, and feeds the data back to the control system, which automatically adjusts the height of the cleaning component 2 to keep the nozzle 26 and the support arm surface at the optimal cleaning distance (such as 10-30cm), avoiding excessive impact due to too close a distance or insufficient cleaning force due to too far a distance.

[0032] An external water source is connected through the inlet pipe 23 and flows through the branch pipe 24 into the flat distribution box 25 at the bottom. The guide baffle inside the distribution box 25 evenly distributes the cleaning fluid to multiple nozzles 26, ensuring that the flow rate of each nozzle 26 is consistent. The nozzles 26 adopt a fan-shaped atomizing structure and the spray angle can be adjusted (e.g., 30°-90°) to cover the flat, curved, and recessed areas of the support arm. The nozzles 26 are arranged at equal intervals along the inner side of the distribution box 25 to form a dense spray matrix, cleaning the support arm surface without dead angles and effectively removing oil and debris.

[0033] The groove 32 on the mounting plate 31 allows the mounting piece 33 to slide horizontally. After being fixed by bolts, the position sensor 34 (infrared beam or laser rangefinder) can adjust its position according to the position of the support arm processing part to ensure that the detection range covers the entire support arm processing part. During the cleaning process, the position sensor 34 continuously monitors the position deviation of the support arm. If the support arm moves up or down, the system automatically triggers the adjustment component 1 to fine-tune the position of the cleaning component 2 to ensure that the nozzle 26 is always aligned with the target area to avoid missed cleaning or over-cleaning.

[0034] Coordinated operation: The support arm is fixed at the cleaning equipment station. The control system adjusts the cleaning component 2 to the initial height (the spacing of the grating sensor 19 is calibrated) according to the workpiece size parameters via the adjusting component 1. The position sensor 34 on the positioning component 3 confirms the position and height of the support arm, generates the coordinates of the cleaning area, and adjusts the angle of the nozzle 26 to match the curved surface of the workpiece. The cleaning fluid flows into the distribution box 25 through the inlet pipe 23 and the branch pipe 24, and is atomized and sprayed through the nozzle 26. The motor 13 drives the cleaning component 2 to move vertically up and down along the mounting frame 11 to complete the cleaning of the support arm. After cleaning, the adjusting component 1 lifts the cleaning component 2 to the standby position to wait for the next workpiece to be processed.
