[0034] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0035] The embodiment of the present application discloses an AF plasma plating device.

[0036] Reference Figure 1-Figure 3, an AF plasma plating device, comprising a frame 1, a plasma irradiation head 11 and a rolling conveyor, wherein the rolling conveyor for conveying glass is installed in the middle of the frame 1, a plasma irradiation head 11 is installed at the top and bottom of the frame 1, and the two plasma irradiation heads 11 are respectively arranged on the upper and lower sides of the glass, and the rolling conveyor comprises a rotating drive mechanism 2, a roller spacing adjustment mechanism 3 and a plurality of roller assemblies 4, the roller spacing adjustment mechanism 3 comprises a transverse guide rail, an adjustment slider 32 and a translation driver 33, an adjustment slider 32 is slidably installed on the transverse guide rail 31, a bearing seat is fixedly installed on the adjustment slider 32, and a rotating drive 33 is installed on the bearing seat A rolling strip assembly 4 is installed, and the rotation drive mechanism 2 includes a servo motor 21, a transverse worm 22 and a turbine 23. The output end of the servo motor 21 is fixedly connected to the transverse worm 22, and the transverse worm 22 is rotatably installed on the frame 1. The transverse worm 22 is meshed with the turbine 23, and the turbine 23 is fixedly connected to the rolling strip assembly 4. A brake 5 is provided between the bearing seat and the rolling strip assembly 4, and the brake 5 is used to control the rolling strip assembly 4 to stop rotating to achieve circumferential fixation. A lifting mechanism 34 is provided between the transverse guide rail 31 and the frame 1, and the lifting mechanism 34 is used to control the up and down movement of the transverse guide rail 31 to achieve the meshing or separation of the turbine 23 and the transverse worm 22.

[0037] Working principle: A rolling conveyor is installed in the middle of the frame 1 of the device, which is specially designed for conveying glass. Plasma irradiation heads 11 are installed at the top and bottom of the frame 1 respectively to ensure that the upper and lower sides of the glass can receive plasma treatment. The plasma irradiation head 11 treats the surface of the glass by generating plasma. This treatment can activate the glass surface and increase its surface energy, thereby improving the adhesion performance of the coating. In the plasma, active particles such as electrons, ions, and free radicals react with the glass surface to achieve the purposes of cleaning, activation, and modification. This process can not only remove surface impurities, but also enhance the surface properties of the material, such as hydrophilicity, dyeability, and adhesion. The rolling conveyor consists of a rotary drive mechanism 2, a rolling bar spacing adjustment mechanism 3, and a rolling bar assembly 4. The rotary drive mechanism 2 is controlled by a servo motor 21, which drives the transverse worm 22 to rotate, driving the turbine 23 and the rolling bar assembly 4 to rotate stably. When the rolling bar spacing needs to be adjusted, the brake 5 controls the rolling bar assembly 4 to stop rotating to achieve circumferential fixation. The lifting mechanism 34 drives the transverse guide rail 31 downward to separate the turbine 23 and the transverse worm 22. The translation driver 33 drives the adjustment slider 32 to slide on the transverse guide rail 31 to adjust the spacing between the rolling strip assemblies 4 to adapt to different sizes of glass. After the spacing is adjusted, the lifting mechanism 34 drives the transverse guide rail 31 upward to re-engage the turbine 23 and the transverse worm 22 to ensure that a larger area on the back of the glass cover can be fully processed. After the processing is completed, the brake stops braking the rolling strip assembly 4, and the rotary drive mechanism 2 controls the glass cover 12 to be transported outward.

[0038] As attached Figure 2 The translation driver 33 includes a translation motor, a worm gear reducer and a gear rack mechanism. The translation motor is fixedly installed on the adjustment slider 32, and the translation motor is connected to the worm gear reducer. A gear rack mechanism is arranged between the worm gear reducer and the transverse guide rail, and the rack is fixedly installed on the transverse guide rail. When the spacing between the rolling strip assemblies 4 needs to be adjusted, the translation motor is started and rotated, and the worm gear reducer reduces the speed and increases the torque, so that the driving gear moves on the rack to realize the linear movement of the adjustment slider 32 along the transverse guide rail 31. Since the bearing seat is fixedly installed on the adjustment slider 32, the spacing of the entire rolling strip assembly 4 will be adjusted accordingly to adapt to glass plates of different widths. The translation driver 33 not only provides precise adjustment capability, but also ensures the stability and reliability of the adjustment process.

[0039] The brake 5 includes a cylinder 51, a transverse support rod 52 and a push rod 53. The push rod 53 is connected to the bearing seat in an up-and-down sliding manner. A brake pad is provided at one end of the push rod 53, and the brake pad cooperates with the rolling strip assembly 4. The other end of the push rod 53 is connected to the transverse support rod 52 in a transverse sliding manner. The cylinder 51 is fixedly installed between the transverse support rod 52 and the transverse guide rail. The cylinder 51 serves as the power source of the brake 5. By controlling the inlet and outlet of compressed air, the push rod 53 can be moved up and down. When the rolling strip assembly 4 needs to be braked, the cylinder 51 will move to push the push rod 53 upward, so that the brake pad on the push rod 53 contacts and presses the rolling strip assembly 4 to achieve braking. When the brake needs to be released, the cylinder 51 will be retracted, the push rod 53 will drop accordingly, and the brake pad will be separated from the rolling strip assembly 4, thereby releasing the brake. This design enables the brake 5 to accurately control the rotation state of the rolling strip assembly 4, and achieve circumferential fixation or release to meet different process requirements.

[0040] As attached Figure 4 As shown, in order to adjust the size of the rolling strip, the rolling strip assembly 4 includes a rolling body 41, an end cover 42 and a central shaft 43. The central shaft 43 is fixedly connected to the end cover 42, and the central shaft 43 is rotatably connected to the bearing seat. The end cover 42 is provided with radial grooves 44 distributed circumferentially, and radial sliders 45 are slidably installed on the radial grooves 44. The rolling body 41 is fixedly installed between the radial sliders 45 on the end covers 42 on both sides, and a center distance adjustment device 6 is provided between the radial sliders 45 and the central shaft 43. When the size of the rolling strip assembly 4 needs to be adjusted to adapt to glasses of different sizes, the center distance between the rolling bodies 41 can be adjusted by operating the center distance adjustment device 6. The radial slider 45 moves along the radial groove 44, and as the center distance changes, the relative position of the rolling body 41 is driven to change, so as to adjust the diameter size of the rolling strip assembly 4.

[0041] The center distance adjustment device 6 includes a slip ring 61, an axial telescopic rod 62 and a linkage rod 63. The slip ring 61 is slidably mounted on the central shaft 43. A linkage rod 64 is hinged between the slip ring 61 and the radial slider 45. The axial telescopic rod 62 is fixedly connected to the transverse guide rail. The telescopic end of the axial telescopic rod 62 is fixedly connected to the linkage rod 63. The linkage rod 63 is provided with a limit track groove 65. The limit track groove 65 and the slip ring 61 are rollingly matched. When the center distance of the rolling strip assembly 4 needs to be adjusted, it can be achieved by operating the axial telescopic rod 62. The extension and contraction of the axial telescopic rod 62 will drive the linkage rod 63 to move. The limit track groove 65 on the linkage rod 63 is rollingly matched with the slip ring 61. The slip ring 61 moves axially, and then transmits power to the radial slider 45 through the linkage rod 64. The radial slider 45 is slidably adjusted to the position on the radial slide groove 44, and finally the position of the rolling body 41 is adjusted. This design makes the adjustment of the rolling bar assembly 4 flexible and precise. The operator can adjust the diameter of the rolling bar assembly 4 according to the width of the glass plate to ensure the stability and adaptability of the glass plate during the transportation process.

[0042] As attached Figure 5-Figure 7 As shown, in order to realize the automatic turning over of the glass cover plate, a glass turning robot 7 is also included, and the glass turning robot 7 includes a lifting arm 71, a transverse telescopic arm 72, a turning table 73, a vertical telescopic arm 74, a first suction cup unit 75 and a second suction cup unit 76. The frame 1 is fixedly connected to the lifting arm 71, and the transverse telescopic arm 72 and the vertical telescopic arm 74 are fixedly installed on the lifting arm 71. The transverse telescopic arm 72 is located below the vertical telescopic arm 74. The transverse telescopic arm 72 is connected to the turning table 73, and the first suction cup unit 75 is fixedly installed on the turning table 73. The second suction cup unit 76 is fixedly installed at the lower end of the vertical telescopic arm 74. During the automatic flipping process, the lifting arm 71 first moves the entire manipulator to an appropriate height, the first suction cup unit 75 sucks the upper side of the glass cover plate, the lifting arm 71 drives the horizontal telescopic arm 72 and the first suction cup unit 75 to move upward, lift the glass cover plate, and the flip table 73 flips 180 degrees, flipping the lower side to the upper side, and then the vertical telescopic arm 74 extends to allow the second suction cup unit 76 to suck the upper side of the glass cover plate, the first suction cup unit 75 releases the glass, the horizontal telescopic arm 72 removes the first suction cup unit 75, and the lifting arm 71 moves the entire manipulator to an appropriate height, while the vertical telescopic arm 74 continues to extend, placing the glass cover plate on the table, completing the flipping operation of the glass cover plate. An axial linear module 77 is provided between the lifting arm 71 and the frame 1, which is used to control the entire manipulator to perform axial displacement and increase the degree of freedom in one direction.

[0043] As attached Figure 8-Figure 10In order to reduce the direct contact of human hands with the glass cover plate for adjustment, the equipment also includes a glass fine-tuning positioning device 8, the main function of which is to fine-tune the position of the glass cover plate to ensure the precise positioning of the glass during the plasma treatment process. The glass fine-tuning positioning device 8 includes a rotating motor, a positioning roller 81 and a push-pull rod 82. The positioning roller 81 is rotatably mounted on the frame 1 or one of the bearing seats. One end of the positioning roller 81 is connected to the rotating motor. The first positioning plate 83 is fixedly mounted on the positioning roller 81 for contacting with the glass and positioning the position of the glass in the conveying direction. The second positioning plate 84 is slidably mounted on both ends of the positioning roller 81. A push-pull rod 82 is provided between the second positioning plate 84 and the positioning roller 81.
