Technical Field

[0001] The utility model relates to the field of potting glue degassing, in particular to a potting glue degassing mechanism. Background Art

[0002] Potting is the process of mechanically or manually pouring liquid polyurethane compounds into devices equipped with electronic components and circuits, and curing them at room temperature or under heating conditions to become thermosetting polymer insulating materials with excellent performance. During the curing process of the potting compound, bubbles are generated due to the action of external forces. When there are too many bubbles, it will affect the performance of the potting compound. It is necessary to use certain methods to remove the bubbles to improve its adhesion.

[0003] After the potting glue in the prior art is injected into the potting mold containing electronic components, the bubbles in the potting glue are generally discharged by vacuum degassing. The mold containing the electronic components is placed in a vacuum degassing device, and the air in the device is extracted to degas the potting glue.

[0004] With respect to the above-mentioned related technologies, in actual use, the existing potting glue degassing mechanism needs to be used in conjunction with a mold of corresponding height because capacitors or other components of different heights may be installed on the surface of the circuit board. This requires that sufficient space be reserved in the vacuum degassing equipment. A large amount of air needs to be extracted each time the degassing work is performed, which seriously reduces the degassing efficiency of the degassing mechanism. In summary, the existing potting glue degassing mechanism is not easy to adjust the volume of the internal space according to actual needs. Utility Model Content

[0009] By adopting the above technical solution, the box body is automatically lifted after being pushed in, and the lifted box body is adsorbed under the vacuum assembly under the negative pressure of the vacuum assembly.

[0010] The utility model is further configured that a guide groove is arranged in the base along the sliding direction of the box body, and a guide strip matching the guide groove is fixedly connected to the bottom surface of the box body.

[0011] By adopting the above technical solution, the guiding of the sliding of the box body is achieved by utilizing the cooperation between the guiding groove and the guiding strip.

[0012] The utility model is further configured such that the height of the guide groove is greater than the sum of the heights of the guide strip and the fixed foot.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] Embodiment 1

[0034] A potting glue degassing mechanism, such as Figure 1-7 As shown, it includes a base 1, a shell 2 is fixedly connected to the top of the base 1, and a vacuum assembly 4 facing downward is arranged in the shell 2. Specifically, the vacuum assembly 4 includes a vacuum air pump and a flat plate with a size larger than the top of the box body 3, the flat plate is parallel to the top surface of the box body 3, and a plurality of air suction ports 5 are arranged in the middle. The box body 3 is slidably connected to the base 1, and a lifting plate 7 is slidably connected to the box body 3 in a vertical direction. The bottom end of the box body 3 is connected to a liquid pump 9, and a liquid storage tank 10 is fixedly connected to one side of the liquid pump 9. The box body 3 and the liquid pump 9 and the liquid pumps 9 are all connected through infusion tubes. Specifically, the liquid between the box body 3 and the liquid storage tank 10 is transported by the liquid pump 9 to realize liquid exchange between the two, thereby achieving the purpose of controlling the liquid level in the box body 3. A float box 8 is fixedly connected to the bottom surface of the lifting plate 7, and the lifting plate 7 floats on the liquid surface in the box body 3 using the float box 8.

[0035] See also Figure 2-5 A plurality of vertical fixing columns 6 are fixedly connected in the box body 3, and the lifting plate 7 is slidably connected to the plurality of fixing columns 6. The fixing columns 6 are used to guide the lifting and lowering of the lifting plate 7, so that the lifting plate 7 can maintain vertical lifting relative to the inner wall of the box body 3 in the box body 3. A sealing ring 11 is fixedly connected to the edge of the box body 3, and the sealing ring 11 can further improve the sealing performance between the box body 3 and the vacuum assembly 4. A handle is fixedly connected to the box body 3 near the opening of the shell 2, and the box body 3 can be easily pulled out or pushed in by holding the handle.

[0036] Embodiment 2

[0037] A potting glue degassing mechanism, such as Figure 1-7 As shown, on the basis of embodiment 1, the difference from embodiment 1 lies in that a slope 15 is provided at a position of the bottom end of the base 1 away from the opening of the shell 2, and a fixed foot 14 with the same height as the slope 15 is fixedly connected to a position of the bottom end of the box body 3 away from the slope 15. When one end of the box body 3 contacts the top of the slope 15, the top of the box body 3 contacts the vacuum assembly 4. During the process of pushing the box body 3 in, the fixed foot 14 is used to lift one end of the box body 3, and the other end of the box body 3 is lifted after the box body 3 contacts the slope 15, thereby realizing automatic lifting of the box body 3 after being pushed in. The lifted box body 3 is adsorbed under the vacuum assembly 4 by the negative pressure of the vacuum assembly 4.

[0038] See also Figure 2-7A guide groove 12 is provided in the base 1 along the sliding direction of the box body 3, and a guide bar 13 matching the guide groove 12 is fixedly connected to the bottom surface of the box body 3. The guide groove 12 and the guide bar 13 cooperate with each other to guide the sliding of the box body 3. The height of the guide groove 12 is greater than the sum of the heights of the guide bar 13 and the fixed foot 14, so as to prevent the guide bar 13 from contacting the bottom end of the guide groove 12 and affecting the normal descent of the box body 3.

[0039] The working principle of the utility model is as follows: the electronic device after the potting glue is placed in the box body 3 with the liquid level adjusted, the liquid level height in the box body 3 makes the lifting plate 7 float at a suitable height, after the electronic device after the potting glue is placed on the lifting plate 7, the top of the electronic device is flush with the top surface of the box body 3, effectively reducing the space of air in the box body 3 at this time, and at the same time does not affect the normal placement of the electronic device, and the box body 3 is pushed into the base 1 until the fixed foot 14 contacts the surface of the base 1, so that one end of the box body 3 provided with the fixed foot 14 is higher than the other end, and as the box body 3 continues to slide, the other end of the box body 3 contacts the slope 15 and slides upward along the slope 15 until the box body 3 is restored to a horizontal state, and the sealing ring 11 at the edge of the box body 3 contacts the vacuum component 4, and the vacuum component 4 can effectively extract the air in the box body 3. After the defoaming work is completed, the vacuum component 4 releases the pressure to restore the inside of the box body 3 to the atmospheric pressure. At this time, the box body 3 is pulled, and the end of the box body 3 close to the slope 15 slides down from the slope 15, and the box body 3 can be easily pulled out, which is convenient for the subsequent rapid replacement of electronic devices in the box body 3.
