AI Technical Summary
In the existing capping process, the concentricity of the gasket is poor, making operation inconvenient and inefficient.
A capping device was designed, comprising a first tank and a second tank. By using negative pressure to adsorb the bottom of the pad and utilizing the movement of the sleeve, the pad and the cap are ensured to be concentrically positioned. Combined with a negative pressure generating device and a limiting structure, the pad and the cap are precisely bonded.
This improved the concentricity of the gasket and the cover, reduced the difficulty of operation, and improved the process quality and operational efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] like Figure 1 As shown, this embodiment discloses a capping device, including a base 1. The base 1 includes an extension platform 11 located at the top, which extends upward along the top surface of the base 1 to form a cylindrical structure. A groove 12 is provided at the top of the extension platform 11, penetrating the upper surface of the extension platform 11. The groove 12 has a circular cross-section. Figure 2 As shown, the trough 12 is used to place the gasket 5. The outer diameter of the gasket 5 matches that of the trough 12 so that the concentricity between the gasket 5 and the trough 12 is improved after the gasket 5 is placed in the trough 12.
[0027] like Figure 1 As shown, the base 1 has a channel 13. One end of the channel 13 is connected to the groove 12, and the other end of the channel 13 extends out of the outer wall of the base 1 and is connected to a negative pressure generating device through an air pipe, so that a negative pressure can be formed in the cavity of the channel 13, thereby sucking the bottom surface of the gasket 5 in the groove 12. Figure 4 The diagram shows the original state of gasket 5. Gasket 5 includes an adhesive layer on its end face 51. In its original state, a protective layer 52 is adhered to the end face 51. The protective layer 52 needs to be peeled off before the end face 51 can be bonded to other components. After gasket 5 is placed into the groove 12, as... Figure 2 As shown, the end face 51 is set upwards, and the negative pressure in the channel 13 sucks the gasket 5, thereby making it easy to tear off the protective layer 52 of the end face 51.
[0028] like Figure 1 As shown, a sleeve 2 is slidably connected to the outer wall of the extension platform 11. The sleeve 2 is at least partially fitted into the extension platform 11 and can move up and down along the outer wall of the extension platform 11. A spring 3 is fitted onto the extension platform 11. The lower end of the spring 3 abuts against the base 1, and the upper end of the spring 3 abuts against the bottom of the sleeve 2.
[0029] like Figure 1As shown, the sleeve 2 has a through hole 21, which axially penetrates the sleeve 2, and the top of the extension platform 11 is inserted into the through hole 21. The outer wall of the extension platform 11 has a limiting groove 14, which penetrates one side of the outer wall of the extension platform 11, and the length of the limiting groove 14 is axially aligned with the extension platform 11. A limiting component 4 is fixedly installed on the sleeve 2. The limiting component 4 is threaded through the sleeve 2, with one axial end located radially outward of the sleeve 2, and the other axial end inserted into the limiting groove 14. The limiting component 4 can move up and down along the inner wall of the limiting groove 14. When the sleeve 2 is at its upper limit position, the upper end of the limiting component 4 abuts against the upper wall of the limiting groove 14 to prevent the sleeve 2 from detaching upward from the extension platform 11.
[0030] The top of the sleeve 2 is provided with a second groove 22, which extends radially outward along the through hole 21. The diameter of the second groove 22 is larger than the outer diameter of the extension platform 11. When the sleeve 2 is in the upper limit position, the second groove 22 is located above the first groove 12.
[0031] When placing the gasket 5, move the sleeve 2 downward so that the top of the extension table 11 extends beyond the upper end of the sleeve 2, thereby facilitating the placement of the gasket 5.
[0032] The cross-section of the second trough (22) is circular and matches the outer diameter of the cover (6), such as... Figure 2 , Figure 3 As shown, the cover 6 is placed into the second groove 22, and the bottom surface of the cover 6 is bonded to the end face 51. The second groove 22 and the first groove 12 are set to be concentric to ensure that the cover 6 is concentric after the gasket 5 is bonded to it.
[0033] The above-mentioned capping device includes the following usage steps:
[0034] ① Press down the sleeve 2, the sleeve 2 moves downward, the top of the extension platform 11 extends out of the upper end of the sleeve 2, the end face 51 of the gasket 5 faces upward and is placed into the groove 12, the bottom of the gasket 5 is sucked by the negative pressure in the channel 13.
[0035] ② Tear off the protective layer 52 at the top of end face 51.
[0036] ③ Loosen the sleeve 2 and move the sleeve 2 upward to the upper limit position. At this time, the second groove 22 is located above the first groove 12. The cover 6 is placed into the second groove 22. A gap is formed between the cover 6 and the end face 51 to prevent the cover 6 from sticking to the end face 51 in advance when it is placed into the second groove 22, which would result in misalignment.
[0037] ④ Press down the cover 6, the cover 6 presses down the end face 51, and the cover 6 is bonded to the end face 51.
[0038] ⑤ Press down the sleeve 2, the sleeve 2 moves downward, the cover 6 separates from the sleeve 2, and the cover 6 with the gasket 5 is removed.
[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
