DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0030] Please refer to Figures 1-8In the embodiment of the present application, a roll coating robot with curved surface self-adaptive capability comprises a base 101 and a robot body arranged on the base 101; according to whether the base 101 is used, the roll coating robot is arranged in two working modes;
[0031] In the first working mode, the robot body is combined and installed with the base 101 as a whole when the base 101 is used, as shown in the state of Figure 1 In this state, the base 101 is placed on the ground or other supports, and the object to be coated is placed on the base 101 by manual or external feeding equipment, and the roll coating operation is performed by the robot body, and the object is removed after the roll coating is completed;
[0032] The robot body comprises a roll coating mechanism 3 and a translation mechanism 2 for driving the roll coating mechanism 3 to move in parallel; the roll coating mechanism 3 comprises a mounting frame 301, and a plurality of self-adaptive roll coating units 302 are fixedly installed at the bottom of the mounting frame 301, as shown in Figures 2-4 The self-adaptive roll coating unit 302 comprises an adjusting frame 3021, a roller frame 3026 is slidably connected to the bottom of the adjusting frame 3021, coating rollers 3027 are rotatably connected to the two sides of the roller frame 3026, a linear motor 3022 is fixedly installed in the inner wall of the adjusting frame 3021, an adjusting rod 3023 is fixedly connected to the output end of the linear motor 3022, an adjusting groove is formed in the bottom of the adjusting rod 3023, the top of the roller frame 3026 is slidably connected to the inner wall of the adjusting groove, and the integrated coating roller in the common roll coating equipment is divided into a plurality of self-adaptive roll coating units 302 which move independently, and the linear motor 3022 drives the coating roller 3027 to move up and down, thereby meeting the coating needs of different shapes of curved surface positions;
[0033] In order to ensure that each coating roller 3027 has sufficient contact pressure with the object to be coated, thereby ensuring the stable operation of the roll coating, as shown in Figure 3The inner wall of the adjusting groove is fixedly connected with a pressure sensor 3024 at one end, and the top of the roller frame 3026 is fixedly connected with a pushing spring 3025.
