[0045] Preferably, after each dispensing operation, the pneumatic element 42 will perform a small suction to retract the glue to reduce the phenomenon of glue stringing. In other embodiments, the glue storage cylinder 43 can also be made of stainless steel, and a glass liquid level observation window can be provided on the cylinder wall of the glue storage cylinder 43; the glue storage cylinder 43 and the support plate 41 can also be an integrated structure; or the glue storage cylinder 43 can be clamped on the support plate 41, and the design of the first pressing plate 46 is not required.

[0046] Reference Figure 1 and Figure 2In this embodiment, the glue dispensing component 4 also includes a mounting plate 44, a positioning plate 45 and a first pressing plate 46; the mounting plate 44 and the positioning plate 45 are parallel to the horizontal plane and fixed on the movable seat 32; the mounting plate 44 is used for detachably mounting the support plate 41; the positioning plate 45 is located below the mounting plate 44, and a plurality of limiting holes 451 are provided on the positioning plate 45 according to the spacing between the plurality of glue storage cylinders 43, and the limiting holes 451 are used for inserting the glue dispensing needle tube 431 to limit the movement of the glue dispensing needle tube 431; the first pressing plate 46 is parallel to the mounting plate 44 and inserted on the movable seat 32, and a side of the first pressing plate 46 close to the mounting plate 44 is used to abut against the end face of the second end of the glue storage cylinder 43; after the support plate 41 is installed on the mounting plate 44, the support plate 41 inserted on the movable seat 32 can limit the relative displacement between the glue storage cylinder 43 and the support plate 41.

[0049] The implementation principle of Example 1 is as follows: First, pre-install the valve core seat 100 on the support column 23 of the mold base 21, and place the mold base 21 on the mounting platform 1, and fix the mold base 21 at a predetermined position by the cooperation of the positioning block 221 and the second telescopic driving member 222. Next, start the moving assembly 31 to drive the moving seat 32 to move to a predetermined position along the three directions of X, Y, and Z, so that the glue needle 431 of the glue storage cylinder 43 is aligned with the opening on the valve core seat 100. Then, the pneumatic element 42 starts to work, injects gas into the glue storage cylinder 43, and forces the glue to flow from the glue needle 431 into the opening of the valve core seat 100. When each valve core seat 100 is fully glued, the pneumatic element 42 reverses the air pumping to suck the excess glue into the glue storage cylinder 43 to avoid glue overflow and waste. Finally, repeat the above process until all valve core seats 100 are evenly glued. In addition, when the glue in the glue storage cylinder 43 is used up, a batch of glue storage cylinders 43 filled with glue can be quickly replaced by removing the support plate 41. During the entire dispensing process, the precise positioning mechanism 2 and the stable moving mechanism 3 ensure that each valve core seat 100 can obtain the same amount of glue, thereby significantly improving the quality and efficiency of dispensing.

[0053] Preferably, a heating wire 5 is provided on the switch plate 49, and the heating wire 5 can heat the switch plate 49 to soften the glue when the glue solidifies and blocks the switch hole 491; sealing rings 6 are provided at the openings at both ends of the switch hole 491, and the sealing rings 6 can be selected from rubber sealing rings or nylon sealing rings. The design of the sealing rings 6 can improve the sealing performance of the switch hole 491. In other embodiments, the heating wire 5 can also be replaced by other simple heating devices.

[0054] The implementation principle of Example 2 is as follows: when in a non-working state, the first telescopic drive component 47 can accurately control the position of the glue dispensing needle 431 in the switch hole 491, so that the glue outlet hole 4311 is completely located in the switch hole 491 and is blocked by the hole wall of the switch hole 491 to prevent glue leakage; this design does not need to rely on the pneumatic element 42 to extract the gas in the glue storage cylinder 43 to absorb the glue, thereby avoiding the problem of bubbles generated in the glue when the pneumatic element 42 extracts the gas in the glue storage cylinder 43; in addition, the pneumatic element 42 can also draw the glue storage cylinder 43 into a vacuum, further eliminating tiny bubbles in the glue, thereby further improving the yield rate.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
