[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 7As shown, in an embodiment of the present invention, a screen partition frame assembly device with a spray-coated antibacterial coating includes a spraying device 1, a pneumatic diaphragm pump 10 is installed on the top of the spraying device 1, the output end of the pneumatic diaphragm pump 10 is connected to a second connecting pipe 9, the bottom end of the second connecting pipe 9 is evenly installed with a first connecting pipe 8, and the bottom end of each first connecting pipe 8 is fixedly connected to a spray head 7; A fixed plate 2 is installed inside the spraying equipment 1, and two fixed plates 2 are symmetrically arranged. A first cylinder 6 is installed on the side wall of one of the fixed plates 2, and a transmission disk 3 is installed on one side of both fixed plates 2. A first rotating shaft 4 is fixedly connected to one side of one of the transmission disks 3, and a motor 5 is installed on the end of the first rotating shaft 4 away from the transmission disk 3.

[0021] The input end of the pneumatic diaphragm pump 10 is connected to the external paint tank; During operation, first place the screen partition frame between the two transmission disks 3, and drive the first cylinder 6 to drive one of the fixed plates 2 to move, so that the two transmission disks 3 clamp and fix the two sides of the screen partition frame, then start the motor 5 to drive the first rotating shaft 4 to rotate, and the rotation of the first rotating shaft 4 drives the rotation of the transmission disk 3, so that the two transmission disks 3 clamp the screen partition frame to rotate, and the external paint is extracted through the pneumatic diaphragm pump 10 through the connection of the second connecting pipe 9, the first connecting pipe 8 and the nozzle 7, and the antibacterial coating is sprayed on the entire outer surface of the screen partition frame, which helps to improve the overall assembly efficiency.

[0022] like Figure 2 、 Figure 4 and Figure 6 As shown, the two transmission plates 3 are rotationally connected to the fixed plate 2 .

[0023] During operation, the screen partition frame can be placed on top of the two bearing plates 11 to facilitate adjustment of the position of the screen partition frame and fixation thereof.

[0024] like Figure 2 、 Figure 4 and Figure 6 As shown, a supporting plate 11 is installed at the bottom of the fixed plate 2, and the supporting plate 11 is rotatably connected to the fixed plate 2 through a rotating assembly.

[0025] like Figures 1 to 7 As shown, the rotating assembly includes a second rotating shaft 12 rotatably mounted on the bottom of the fixed plate 2, the second rotating shaft 12 is fixedly connected to the supporting plate 11, a movable seat 13 is installed at one end of the second rotating shaft 12, and a transmission shaft 15 is rotatably mounted inside the movable seat 13 through a transmission assembly, and a spiral groove 16 is provided on the outer wall of the transmission shaft 15, and a slider 17 is slidably connected to the inner wall of the spiral groove 16, and the slider 17 is fixedly mounted on the inner wall of the movable shaft 18, and a connecting plate 19 is provided on the top of the movable shaft 18, and a second cylinder 20 is installed on the top of the connecting plate 19.

[0026] After the screen partition frame is fixed, the connecting plate 19 is driven downward by the second cylinder 20. The movement of the connecting plate 19 drives the movable shaft 18 to move downward. The movement of the movable shaft 18 drives the slider 17 to slide on the inner wall of the spiral groove 16, thereby driving the transmission shaft 15 to rotate, and the second rotating shaft 12 is caused to rotate through the connection of the transmission component. The rotation of the second rotating shaft 12 drives the rotation of the supporting plate 11, so that the supporting plate 11 and the fixed plate 2 are changed from vertical to horizontal, thereby reducing the obstruction of the screen partition frame by the supporting plate 11 and improving the comprehensiveness of the spraying.

[0027] like Figure 7 As shown, the transmission assembly includes a worm gear 14 installed inside the movable seat 13 , the worm gear 14 is fixedly connected to the second rotating shaft 12 , one side of the worm gear 14 is meshedly connected with a worm 27 , and the top end of the worm 27 is fixedly connected to the transmission shaft 15 .

[0028] When the connecting plate 19 is driven downward by the second cylinder 20 to drive the transmission shaft 15 to rotate, the rotation of the transmission shaft 15 drives the rotation of the worm 27, and the rotation of the worm 27 drives the worm wheel 14 to rotate, thereby driving the rotation of the supporting plate 11. The transmission through the worm 27 and the worm wheel 14 makes the overall structure self-locking, preventing the supporting plate 11 from rotating downward due to its own gravity when the screen partition frame is installed, thereby affecting the installation stability, thereby improving the stability and reliability of the device.

[0029] like Figure 6 As shown, a spring 26 is provided at the bottom of the moving shaft 18 , and the spring 26 is installed on the top of the moving seat 13 .

[0030] When the connecting plate 19 drives the movable shaft 18 to move downward, the spring 26 deforms and stores elastic potential energy; After the connecting plate 19 moves upward, the elastic potential energy released by the spring 26 drives the movable shaft 18 to move upward and reset, so that the supporting plate 11 rotates to the bottom of the fixed plate 2 and is perpendicular to it.

[0031] like Figure 2 and Figure 3 As shown, one of the movable seats 13 is slidably installed inside the slide groove 21, and the slide groove 21 is opened on the inner wall of the spraying equipment 1.

[0032] When the screen partition frame is fixed, the first cylinder 6 is driven to move one of the fixed plates 2 , and the movement of the fixed plate 2 drives the movement of the second rotating shaft 12 , and the movement of the second rotating shaft 12 drives the movable seat 13 to slide inside the slide groove 21 .

[0033] like Figure 6 As shown, the movable shaft 18 and the connecting plate 19 are slidably connected.

[0034] When the movable seat 13 slides inside the sliding groove 21, the movable shaft 18 above the movable seat 13 slides on the bottom of the connecting plate 19, so that the movable shaft 18 can still be driven to move downward through the connecting plate 19 after moving.

[0035] like Figures 1 to 7 As shown, a rack plate 25 is fixedly installed on the top of one of the movable seats 13, and a gear 24 is meshed and connected to the top of the rack plate 25. A third rotating shaft 23 is fixedly installed on one side of the gear 24, and a ball valve 22 is fixedly installed on the end of the third rotating shaft 23 away from the gear 24. The ball valve 22 is rotatably installed inside the first connecting pipe 8.

[0036] A ball valve 22 is rotatably installed inside a portion of the first connecting pipe 8 , and the ball valve 22 is arranged above the slide groove 21 ; When the movable seat 13 slides inside the slide groove 21, the movement of the movable seat 13 drives the movement of the rack plate 25. After the rack plate 25 moves and engages with the gear 24, it drives the gear 24 to rotate. The rotation of the gear 24 drives the rotation of the third rotating shaft 23. The rotation of the third rotating shaft 23 drives the ball valve 22 to rotate to close the internal channel of the first connecting pipe 8, changing the overall spraying range to adapt to screen partition frames of different lengths, thereby improving the adaptability of the device.

[0037] A method for assembling a screen partition frame with a spray-coated antibacterial coating comprises the following steps: S1: When working, first place the screen partition frame on top of the two bearing plates 11 and adjust the position of the screen partition frame, then drive the first cylinder 6 to drive one of the fixed plates 2 to move closer to the other fixed plate 2, so that the two transmission plates 3 clamp and fix the two sides of the screen partition frame; S2: At the same time, the movement of one of the fixed plates 2 drives the movement of the second rotating shaft 12, and the movement of the second rotating shaft 12 drives the movable seat 13 to slide inside the slide groove 21. The movement of the movable seat 13 drives the movement of the rack plate 25. The rack plate 25 moves and engages with the gear 24, driving the gear 24 to rotate. The rotation of the gear 24 drives the rotation of the third rotating shaft 23. The rotation of the third rotating shaft 23 drives the rotation of the ball valve 22 to close the internal channel of the first connecting pipe 8, so that the spraying range adapts to the length of the screen partition frame; S3: After the screen partition frame is fixed, the connecting plate 19 is driven downward by the second cylinder 20. The movement of the connecting plate 19 drives the movable shaft 18 to move downward. The movement of the movable shaft 18 drives the slider 17 to slide on the inner wall of the spiral groove 16, thereby driving the transmission shaft 15 to rotate. The rotation of the transmission shaft 15 drives the rotation of the worm 27. The rotation of the worm 27 drives the rotation of the worm gear 14. The rotation of the worm gear 14 drives the rotation of the second rotating shaft 12. The rotation of the second rotating shaft 12 drives the rotation of the carrying plate 11, so that the vertical shape between the carrying plate 11 and the fixed plate 2 becomes horizontal, and the carrying plate 11 is separated from the bottom of the screen partition frame to reduce the obstruction of the screen partition frame by the carrying plate 11. S4: Finally, start the motor 5 to drive the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the rotation of the transmission disk 3, so that the two transmission disks 3 clamp the screen partition frame to rotate, and the external paint is extracted through the pneumatic diaphragm pump 10 through the connection of the second connecting pipe 9, the first connecting pipe 8 and the nozzle 7 to spray the antibacterial coating on the entire outer surface of the screen partition frame.
