[0030] Please refer to Figures 1 to 4 As shown in the drawings, the present application provides an automobile windshield bottom coating tool 100, which comprises a tool support 1 and a coating brush 2, and further comprises a moving assembly 3 for driving the tool support 1 and the coating brush 2 to move. The moving assembly 3 comprises a first moving wheel 31 and a second moving wheel 32, the first moving wheel 31 is arranged at the bottom of the tool support 1, the second moving wheel 32 is arranged at the side of the tool support 1, the rotation axis of the first moving wheel 31 and the rotation axis of the second moving wheel 32 intersect, and the first moving wheel 31 and the second moving wheel 32 form a positioning space 30 for positioning a component to be coated.

[0031] The present application adopts the cooperation of the first moving wheel 31 and the second moving wheel 32, so that the automobile windshield bottom coating tool 100 can be well positioned at the corresponding position of the component to be coated, to drive the tool support 1 and the coating brush 2 to move along the coating surface of the component to be coated, with good moving stability and high coating quality. The technical problem that the existing coating operation only relies on visual observation, hand feeling and personal experience, resulting in great physical dependence, poor consistency and inability to meet the requirements of rapid and efficient coating of the whole vehicle is solved. Please refer to Figure 5 As shown in the drawings, in the present embodiment, the component to be coated is a sheet metal part 5 of an automobile body, and the coating surface is a bonding surface on the sheet metal part 5 for bonding with the windshield.

[0032] In the embodiment, the rotation axis of the first moving wheel 31 is perpendicular to the rotation axis of the second moving wheel 32, and a right-angled positioning space 30 is formed between the circumferential surfaces of the first moving wheel 31 and the second moving wheel 32, so as to better position the tool support 1 on the sheet metal part 5 of the automobile and improve the stability of the tool support 1 during movement. Specifically, in use, the first moving wheel 31 contacts the side edge of the sheet metal part 5 of the automobile to walk at the side edge of the coating surface, and the first moving wheel 31 rotates by the friction between the first moving wheel 31 and the sheet metal part 5, thereby driving the tool support 1 to move. The second moving wheel 32 is used to walk on the coating surface of the part to be coated, that is, the second moving wheel 32 is attached to the contact surface of the sheet metal part 5 of the automobile for installing the windshield. In the embodiment, the diameter of the second moving wheel 32 is smaller than the diameter of the first moving wheel 31. The first moving wheel 31 is the driving wheel, which has a relatively large diameter and good movement performance. The second moving wheel 32 is the auxiliary wheel, which has a relatively small diameter and is mainly used for supporting and positioning. The coating brush 2 is fixed to the tool support 1 and located on the same side as the second moving wheel 32. The moving direction of the coating brush 2 is the same as the moving direction of the second moving wheel 32, and the coating brush 2 is located at the rear side of the moving direction of the second moving wheel 32. When the first moving wheel 31 and the second moving wheel 32 rotate to drive the tool support 1 to move, the coating brush 2 also moves, thereby uniformly and high-quality coating the primer on the area of the sheet metal part 5 that is attached to the windshield, and improving the installation quality between the windshield and the sheet metal part 5. It should be noted that the intersection or perpendicularity of the rotation axes in the present document includes the cases of intersection or perpendicularity in the same plane, and also includes the cases of intersection or perpendicularity in space.
