Abstract
Description
Technical Field
[0001] This utility model relates to the field of degassing technology, specifically a dual-shaft stirring vacuum degassing device. Background Technology
[0002] Epoxy thermally conductive potting compound requires the use of vacuum degassing equipment to remove air bubbles.

The device includes a movable base, a storage tank on the movable base, a support rod on one side of the storage tank, a mounting base on the support rod, a control board connected to one side of the mounting base, and a lifting base above the mounting base.
[0003] The aforementioned device uses modular lifting to facilitate the separation of the stirring shaft and the stirring tank, thereby making it easier to clean the device later. However, during the lifting of the stirring shaft and the cover, the center of gravity of the device rises, which reduces the stability of the device and makes it prone to shaking. In severe cases, this can lead to the device tipping over and being damaged. Utility Model Content
[0004] The purpose of this invention is to provide a dual-shaft stirring vacuum degassing device to solve the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 In this embodiment of the present invention, a dual-shaft stirring vacuum degassing device includes a support plate 1, a stirring tank 3 placed on the upper surface of the support plate 1, a cover 302 movably connected to the upper surface of the stirring tank 3, an installation frame 5 fixedly connected to the upper surface of the cover 302, a stirring motor 501 fixedly connected to the upper surface of the installation frame 5, two stirring shafts 502 rotatably connected to the upper surface of the stirring tank 3, stirring blades 504 fixedly connected to the outer surface of the stirring shafts 502, a vacuum generator 6 embedded in the upper surface of the stirring tank 3, and a vacuum pressure gauge 601 embedded in the upper surface of the stirring tank 3.
[0024] A lifting mechanism 4 is provided on the upper surface of the support plate 1. The lifting mechanism 4 includes a fixed frame 401, a second lead screw 402, a second nut 403, a guide plate 404, and a connecting plate 405. The fixed frame 401 is fixedly connected to the upper surface of the support plate 1. The second lead screw 402 is rotatably connected to the inside of the fixed frame 401, and the lower end of the second lead screw 402 passes through the support plate 1. The second nut 403 is threadedly connected to the outer surface of the second lead screw 402. The guide plate 404 is fixedly connected to the outer surface of the second nut 403. The connecting plate 405 is fixedly connected to the outer surface of the guide plate 404. The connecting plate 405 and the mounting frame 5 are fixedly connected.
[0025] A first gear 503 is fixedly connected to the upper end of the stirring shaft 502, and a second gear 505 is fixedly connected to the output end of the stirring motor 501. The first gear 503 and the second gear 505 are meshed together.
[0026] Specifically, during use, the epoxy thermally conductive potting compound is placed inside the mixing tank 3. The vacuum generator 6 creates a vacuum inside the mixing tank 3. The stirring motor 501 is then started. The output of the stirring motor 501, along with the second gear 505 and the first gear 503, drives the two stirring shafts 502 to rotate, causing the stirring blades 504 to stir the epoxy thermally conductive potting compound. This facilitates the removal of internal air bubbles. The cover 302 seals the mixing tank 3. When the second lead screw 402 rotates, the second nut 403, in conjunction with the guide plate 404, drives the connecting plate 405 to rise, causing the mounting frame 5 and the cover 302 to move upwards. This separates the stirring shafts 502 from the mixing tank 3, facilitating the subsequent cleaning of residual adhesive on the mixing tank 3 and the stirring blades 504, and removing external constraints from the upper part of the mixing tank 3.
[0027] Example 1
[0028] like Figure 1-4 As shown, the upper surface of the support plate 1 is provided with a sliding groove 101, the lower surface of the support plate 1 is fixedly connected with a support frame 102, the upper surface of the mixing tank 3 is provided with a groove 301, the lower surface of the cover 302 is fixedly connected with a sealing ring 303, and the outer surface of the mixing tank 3 is fixedly connected with two sockets 304.
[0029] In this embodiment, the plug 203 and the slide groove 101 are slidably connected to guide the sliding of the plug 203. The support frame 102 is used to support the equipment structure. The groove 301 cooperates with the cover 302 to ensure that the cover 302 is sealed with the mixing tank 3. The sealing ring 303 further enhances the sealing effect and prevents vacuum leakage. The plug 203 and the socket 304 are matched to pre-fix the mixing tank 3.
[0030] like Figure 1-4 As shown, a clamping mechanism 2 is slidably connected to the upper surface of the support plate 1. The clamping mechanism 2 includes a plug 203, a first nut 202, and a bidirectional lead screw 201. The plug 203 is embedded and slidably connected to the upper surface of the support plate 1. The first nut 202 is fixedly connected to the lower surface of the plug 203. The bidirectional lead screw 201 is threadedly connected to the inside of the first nut 202. A handwheel 204 is fixedly connected to one end of the bidirectional lead screw 201.
[0031] In this embodiment, the clamping mechanism 2 is used to fix the mixing tank 3 to ensure stability during mixing. By rotating the handwheel 204, the first nut 202 can be adjusted to the position of the bidirectional lead screw 201, thereby adjusting the position of the plug 203 and achieving clamping and fixing of the plug 203 to the mixing tank 3.
[0032] Example 2
[0033] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to keep the device stable after lifting in Embodiment 1.
[0034] like Figure 1-4 As shown, a first lead screw 103 is rotatably connected inside the support frame 102. A first bevel gear 104 is fixedly connected to one end of the first lead screw 103. A second bevel gear 406 is fixedly connected to the lower end of the second lead screw 402. The second bevel gear 406 and the first bevel gear 104 are meshed together. A servo motor 407 is fixedly connected to the upper surface of the fixed frame 401. The output end of the servo motor 407 is fixedly connected to the upper end of the second lead screw 402.
[0035] In this embodiment, when the second lead screw 402 drives the second nut 403 to rise, it can simultaneously drive the second bevel gear 406 to rotate. The second bevel gear 406 drives the first bevel gear 104 to rotate, so that when the cover 302 rises, the first lead screw 103 drives the sliding plate 105 to slide outward under the push of the thread. The servo motor 407 provides power for the rotation of the second lead screw 402.
[0036] like Figure 1-4 As shown, a sliding plate 105 is slidably connected to the inner surface of the support frame 102, the first lead screw 103 is threadedly connected to the sliding plate 105, and a universal ball 106 is rotatably connected to the lower surface of the sliding plate 105.
[0037] In this embodiment, the sliding plate 105 slides within the support frame 102, and its position can be adjusted by rotating the first lead screw 103. The universal ball 106 reduces the friction between the sliding plate 105 and the ground, and increases the support area of the device while raising the center of gravity of the device, thereby improving the stability of the equipment.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
