[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] like Figures 1 to 5 As shown in this embodiment, an automatic silver paint coating device includes a table support 1. A silver paint coating table 2 is fixed to the front side of the table support 1. An auxiliary table 3 is placed on the rear side of the table support 1. Several hand-tightening magnetic adsorption parts 4, hand-tightening pin positioning parts 5, and hand-tightening adjustment sensors 6 are distributed on the silver paint coating table 2. Baffles 7 are provided on the rear and left sides of the silver paint coating table 2. A secondary tilting positioning plate 8 is provided on one side of the auxiliary table 3. Side plates 9 are fixed on the two downward-facing sides of the secondary tilting positioning plate 8. A robot arm 10 is provided on the other side of the auxiliary table 3. A square tube mounting frame 11 is installed on the robot arm 10. A product suction cup 12, a product electromagnet 13, and a product sensor 14 are installed on the square tube mounting frame 11. A steering cylinder 15 is installed on one side of the square tube mounting frame 11. A silver paint pen 16 is locked to the drive end of the steering cylinder 15.
[0026] External mechanical components place the sheet metal plate 28 onto the silver-painted table 2. The robotic arm 10 grips the sheet metal plate 28 using the product suction cup 12 and the product electromagnet 13. At this time, after the product sensor 14 senses the sheet metal plate 28, the robotic arm 10 places it onto the secondary tilting positioning plate 8. Due to its own weight, the sheet metal plate 28 slides down and stops under the action of the side plate 9. Then, the robotic arm 10 grips the sheet metal plate 28 again and places it back onto the silver-painted table 2. The position of the sheet metal plate 28 is fixed according to the pre-placed hand-tightening magnet adsorption component 4 and hand-tightening pin positioning component 5. In addition, after the hand-tightening adjustment sensor 6 senses the sheet metal plate 28, the silver paint pen 16 on the robotic arm 10 begins to move along the edge of the sheet metal plate 28. With the cooperation of the steering cylinder 15, the direction of the silver paint pen 16 can be changed according to the edge position of the sheet metal plate 28 to perform silver paint processing on the sheet metal plate 28.
[0027] The fixed end of the silver paint pen 16 is hinged to the steering cylinder 15. The steering cylinder 15 controls the direction change of the silver paint pen 16. Combined with the positional relationship of the hinge, it ensures that the pen tip of the silver paint pen 16 moves in alignment with the edge of the sheet metal plate 28.
[0028] Several brushes 17 are distributed on the secondary tilting positioning plate 8. A double-sheet detection sensor 18 is installed at the lower corner of the secondary tilting positioning plate 8. A secondary positioning bracket 19 is fixed at the lower end of the secondary tilting positioning plate 8. The brushes 17 effectively protect the surface of the sheet metal plate 28 from scratching. When the side plate 9 abuts against the sheet metal plate 28, the double-sheet detection sensor 18 senses the thickness of the sheet metal plate 28 to prevent the two plates from sticking together. The entire secondary tilting structure is fixed on the auxiliary table 3 by the secondary positioning bracket 19.
[0029] A lifting cylinder 20 is installed on the side of the table support 1. The driving end of the lifting cylinder 20 is connected to a positioning strip 21, which is located inside the baffle 7. A linear bearing 22 is fixed on the table support 1, and a guide shaft 23 is fixed at the lower end of the baffle 7. The guide shaft 23 slides vertically on the linear bearing 22 to control the lifting cylinder 20, so that the positioning strip 21 drives the baffle 7 to rise and fall, and performs the first positioning of the sheet metal plate 28 on the silver-painted table 2. During the lifting process, the guide shaft 23 and the linear bearing 22 provide guidance.
[0030] The front end of the silver-painted part is equipped with a control panel 24, which is used by an operator to control the operation of the entire device. It is used on sheet metal sheets 28 from the same batch.
[0031] An oil pan 25 is fixed to one side of the silver-painted tabletop 2. A movable railing 26 is provided on the outside of the tabletop support 1. A universal caster 27 is installed at the lower end of the movable railing 26. Oil is applied from the oil pan 25. The movable railing 26 is used to adjust the distance of the tabletop support 1 so that people cannot get close and thus prevent interference with the operation of the robotic arm 10.
[0032] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
