The charging barrel 10 is used to store the gel 200 (heat conductive gel) for the filling work. The top of the charging basket 10 is open to form a basket opening, and the first pressing plate 20 is fitted in the basket opening and can move up and down along the charging basket 10 for flattening the gel 200 in the charging basket 10. The second presser plate 30 is disposed on the surface of the first presser plate 20 facing the bottom of the charging bucket 10, and the second presser plate 30 is detachable from the first presser plate 20 and moves up and down along the charging bucket 10 for squeezing out the gas (i.e., forming bubbles) entrapped in the gel 200.
In the structural form, the charging bucket 10 may be a circular bucket as shown in fig. 1, or may be a square bucket or other bucket of various shapes. The barrel mouth is communicated with the space in the charging barrel 10 and has the same shape. The shape of the bung may be identical to the outer peripheral shape of the charging bucket 10, and may be circular or polygonal, etc. The shape of the bung may also be non-conforming to the shape of the periphery of the charging bucket 10, for example for a square charging bucket 10 the bung may be a round bung and vice versa.
The wall of the charging barrel 10 may further be provided with an interlayer 100 for introducing a heat conductive liquid such as a heat conductive oil, so that the gel 200 in the charging barrel 10 may be heated to maintain a desired fluidity. The barrel wall of the charging barrel 10 includes the side wall and also the bottom wall of the charging barrel 10, and the interlayer may be provided in the side wall or the bottom wall, or in both the side wall and the bottom wall.
The first presser plate 20 is detachably fitted in the bung of the charging bucket 10, and thus the shape of the first presser plate 20 is arranged corresponding to the shape of the bung. In the bung, the outer periphery of the first presser plate 20 is closely attached to the inner peripheral wall surface of the charging basket 10, so that the inner chamber of the charging basket 10 can be closed to form a closed chamber, which is beneficial to vacuum pumping.
In order to realize the close contact between the first presser plate 20 and the inner peripheral wall surface of the charging bucket 10, and the first presser plate 20 is movable, a seal ring 21 is fitted around the outer periphery of the first presser plate 20, and the seal ring 21 is sealed between the outer periphery of the first presser plate 20 and the inner peripheral wall surface of the charging bucket 10.

The outer peripheral dimension of the second presser plate 30 is smaller than the outer peripheral dimension of the first presser plate 20, so that a space is left between the outer periphery of the second presser plate 30 and the inner peripheral wall surface of the charging bucket 10. When the second pressing plate 30 presses the gel downward, the gel 200 is not pressed flat, but pressed only on a portion of the gel 200 corresponding to the area of the second pressing plate 30, and the gas entrapped in the gel 200 can be discharged from the space between the second pressing plate 30 and the inner peripheral wall surface of the charging bucket 10 after being pressed.
Corresponding to the second pressing plate 30, a positioning groove 22 adapted to the second pressing plate 30 is provided on the surface of the first pressing plate 20 facing the bottom of the charging bucket 10, and the second pressing plate 30 is detachably fitted in the positioning groove 22. The depth of the positioning groove 22 preferably corresponds to the thickness of the second pressing plate 30, and when the second pressing plate 30 is fitted into the positioning groove 22, the surface of the second pressing plate 30 facing away from the positioning groove 22 can be flush with the surface of the first pressing plate 20 where the positioning groove 22 is located and form a flat and complete surface, so that the gel 200 can be flattened.
In addition, when the second pressing plate 30 is fitted into the positioning groove 22, the outer periphery of the second pressing plate 30 can be tightly fitted with the inner periphery of the positioning groove 22, so that when the first pressing plate 20 is driven to move upward in the charging basket 10 to the opening, the second pressing plate 30 can be driven to move upward at the same time.
As also shown in fig. 1 and 2, the gel filling apparatus of the present invention further includes at least one filling port 40 and a pumping port 50 for pumping vacuum. The filling opening 40 and the suction opening 50 are disposed on the first pressing plate 20 and penetrate through opposite surfaces of the first pressing plate 20, respectively communicating the inner and outer spaces of the charging tub 10.
In cooperation with the second pressing plate 30 having a size smaller than that of the first pressing plate 20, the pumping holes 50 are located in a projected area of the second pressing plate 30 on the first pressing plate 20. After the second pressing plate 30 is attached to the first pressing plate 20, the suction openings 50 on the first pressing plate 20 can be closed at the same time. The filling opening 40 can be arranged in the projection area of the second pressing plate 30 on the first pressing plate 20, and therefore the second pressing plate 30 is provided with a filling through hole which is relatively communicated with the filling opening 40, so that after the second pressing plate 30 is attached to the first pressing plate 20, the filling opening 40 is communicated with the charging barrel 10 through the filling through hole, and the gel output is convenient for filling. Alternatively, the pouring opening 40 may be located outside the projection area of the second pressing plate 30 on the first pressing plate 20, and after the second pressing plate 30 is attached to the first pressing plate 20, the pouring opening 40 is located at the periphery of the second pressing plate 30 and still communicates with the inner cavity of the charging bucket 10.
Further, in order to drive the up and down movement of the first pressing plate 20 and the second pressing plate 30, the gel filling apparatus of the present invention further includes a driving rod 60 connected to the first pressing plate 20, and at least one driving mechanism 70 connected to the second pressing plate 30.
