[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, as shown in Figures 1-4, a vacuum-assisted impregnation device includes a workbench 1, a base plate 11 fixedly connected to the bottom end of the workbench 1, a vacuum pump 12 disposed on the upper surface of the base plate 11 near the workbench 1, impregnation tanks 13 symmetrically disposed on the upper surface of the workbench 1, the inner cavity of the impregnation tank 13 communicating with the input end of the vacuum pump 12, a sealing strip 14 fixedly connected to the outer wall of the impregnation tank 13, an inlet for adhesive in the upper surface of the impregnation tank 13, a valve disposed in the inlet, an opening and closing mechanism 2 for driving the impregnation tank 13 disposed on the outer wall of the workbench 1, and an auxiliary mechanism 3 disposed in the inner cavity of the impregnation tank 13.

[0025] In this embodiment, the impregnation tank 13 is closed by the opening and closing mechanism 2. During the closing process, the auxiliary mechanism 3 restricts the fiberglass cylinder and allows the fiberglass cylinder to enter the inner cavity of the impregnation tank 13. Then, the vacuum pump 12 evacuates the air in the impregnation tank 13 to form a vacuum in the impregnation tank 13. Then, glue is injected into the impregnation tank 13 to complete the impregnation.

[0026] In an optional embodiment, as shown in Figures 1-4, the opening and closing mechanism 2 includes a connecting frame 21. The outer wall of the connecting frame 21 is fixedly connected to the side wall of the worktable 1. A motor 22 is fixedly connected to the outer wall of the connecting frame 21. A first bidirectional screw 23 is fixedly connected to the output end of the motor 22. The outer wall of the first bidirectional screw 23 is rotatably connected to the inner wall of the connecting frame 21. A synchronous belt 25 is connected to the outer wall of the first bidirectional screw 23 via a synchronous pulley. A second bidirectional screw 26 is connected to the inner wall of the synchronous belt 25 away from the first bidirectional screw 23 via a synchronous pulley. The outer walls of the bidirectional screw 26 are symmetrically threaded with first sliders 24. The outer walls of the first sliders 24 are slidably connected to the inner cavity of the connecting frame 21. The top of the first slider 24 is fixedly connected to a connecting block 27. The outer walls of the connecting block 27 are fixedly connected to the outer walls of the impregnation tank 13. When the motor 22 is started, it drives the first bidirectional screw 23 to rotate. The first bidirectional screw 23 drives the synchronous belt 25 and the second bidirectional screw 26 to rotate synchronously, so that the first slider 24 drives the impregnation tank 13 to move synchronously, thereby closing the impregnation tank 13. The sealing strip 14 seals the closed part of the impregnation tank 13 to prevent air leakage.

[0027] In an optional embodiment, as shown in Figures 1-4, the auxiliary mechanism 3 includes a support plate 31. A first movable rod 32 is rotatably connected to the side wall of the support plate 31. The first movable rod 32 is rotatably connected to the inner cavity of the support plate 31 from the outer wall away from the support plate 31. A second slider 38 is slidably connected to the inner wall of the support plate 31. A second movable rod 33 is rotatably connected to the bottom end of the second slider 38. A first guide block 34 is rotatably connected to the outer wall of the second movable rod 33 from the support plate 31. A mounting frame 35 is slidably connected to the outer wall of the first guide block 34. The bottom end of the mounting frame 35 is fixedly connected to the inner cavity of the impregnation tank 13. A sliding rod 36 is slidably connected to the inner wall of the first guide block 34. The end of the sliding rod 36 is fixedly connected to the inner wall of the mounting frame 35. A spring 37 is sleeved on the outer wall of the sliding rod 36. One end is fixedly connected to the inner wall of the mounting frame 35, and the other end is fixedly connected to the outer wall of the first guide block 34. During the closing process of the impregnation tank 13, the impregnation tank 13 drives the first movable rod 32 to rotate downward, causing the first movable rod 32 to drive the support plate 31 to move downward. The support plate 31 drives the second movable rod 33 to move. The second movable rod 33 first drives the second slider 38 to slide on the inner wall of the support plate 31. When the outer wall of the second slider 38 contacts the outer wall of the fiberglass cylinder, the second movable rod 33 drives the first guide block 34 to slide on the outer wall of the slide rod 36, causing the spring 37 to contract. Thus, after the impregnation tank 13 is completely closed, the support plate 31 is at the bottom of the inner cavity of the impregnation tank 13, and the fiberglass cylinder is also located in the inner cavity of the impregnation tank 13. The second slider 38 restricts the fiberglass cylinder to prevent it from shaking.

[0028] In an optional embodiment, as shown in Figures 1-4, limit blocks 15 are symmetrically arranged on the lower surface of the impregnation tank 13. The outer wall of the limit block 15 is slidably connected to the through groove opened on the outer wall of the worktable 1. The limit block 15 restricts the impregnation tank 13, making the movement of the impregnation tank 13 more stable during the closing or opening process.

[0029] In an optional embodiment, as shown in Figures 1-4, a rectangular through-slot is provided on the outer wall of the workbench 1 near the through-slot for liquid leakage, so that after the impregnation tank 13 is opened, the residual impregnation liquid inside can be recycled and reused through the rectangular through-slot.

[0030] In an optional embodiment, as shown in Figures 1-4, the outer wall of the connecting frame 21 is provided with a groove that is adapted to the first slider 24, and the effective sliding distance of the first slider 24 is greater than the sliding distance of the limiting block 15 in the through groove. Thus, when the first slider 24 drives the connecting block 27 and the impregnation box 13 to move, the movement distance will not be too large under the restriction of the limiting block 15.

[0031] In an optional embodiment, as shown in Figures 1-4, a second guide block 39 is fixedly connected to the outer wall of the second slider 38. The outer wall of the second guide block 39 is slidably connected to the inner wall of the support plate 31. Under the action of the second guide block 39, the second slider 38 can only move horizontally on the inner wall of the support plate 31 and cannot move vertically.

[0032] In an optional embodiment, as shown in Figures 1-4, the outer wall of the spring 37 is wrapped with a waterproof material to prevent the spring 37 from aging due to long-term contact with the adhesive.

[0033] The above embodiment discloses a vacuum-assisted impregnation device. When impregnating a fiberglass cylinder, the cylinder is placed on a support plate 31. Then, the motor 22 is started, driving the first bidirectional screw 23 to rotate. The first bidirectional screw 23 drives the synchronous belt 25 and the second bidirectional screw 26 to rotate synchronously, causing the first slider 24 to move the impregnation tank 13 synchronously, thereby closing the impregnation tank 13. A sealing strip 14 seals the closed portion of the impregnation tank 13 to prevent air leakage. During the closing process of the impregnation tank 13, the impregnation tank 13 drives the first movable rod 32 to rotate downwards, causing the first movable rod 32 to move the support plate 31 downwards. The second movable rod 33 moves, first causing the second slider 38 to slide on the inner wall of the support plate 31. When the outer wall of the second slider 38 contacts the outer wall of the fiberglass cylinder, the second movable rod 33 causes the first guide block 34 to slide on the outer wall of the slide rod 36, causing the spring 37 to contract. Thus, after the impregnation tank 13 is completely closed, the support plate 31 is at the bottom of the inner cavity of the impregnation tank 13, and the fiberglass cylinder is also located in the inner cavity of the impregnation tank 13. The second slider 38 restricts the fiberglass cylinder to prevent it from shaking. Then, the vacuum pump 12 extracts the air from the impregnation tank 13, creating a vacuum in the inner cavity of the impregnation tank 13, and evacuates the fiberglass cylinder. Air is extracted from the pores and gaps in the fiberglass cylinder to create a relatively low-pressure area. Then, the outlet of the external glue storage device is connected to the inlet, and the valve at the inlet is opened to allow glue to be introduced into the inner cavity of the impregnation tank 13. Due to the pressure difference between the impregnation tank 13 and the fiberglass cylinder, the glue quickly fills the pores and gaps inside the fiberglass cylinder under pressure, completing the impregnation process. After the impregnation is completed, a pre-prepared liquid container is placed below the rectangular channel, and then the impregnation tank 13 can be opened. During the opening process, the impregnation tank 13 drives the first movable rod 32 to rotate upwards, causing the first movable rod 32 to move the support plate 31 upwards. The support plate 31 drives the second movable rod 33 to rotate synchronously, so that the second slider 38 no longer restricts the fiberglass cylinder. When the impregnation tank 13 is opened to the maximum extent, the glue in the impregnation tank 13 enters the liquid tank through the rectangular channel. The support plate 31 lifts the fiberglass cylinder out of the inner cavity of the impregnation tank 13, making it easy to remove. In summary, the impregnation tank 13 is closed by the opening and closing mechanism 2. During the closing process, the auxiliary mechanism 3 restricts the fiberglass cylinder and allows it to enter the inner cavity of the impregnation tank 13. Then, the vacuum pump 12 evacuates the air in the impregnation tank 13, creating a vacuum inside the impregnation tank 13. Then, glue is injected into the impregnation tank 13 to complete the impregnation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
