Abstract
Description
Technical Field
[0001] This utility model relates to a bottle cap gasket assembly device. Background Technology

[0004] During assembly, first place the bottle cap that needs to be installed with a gasket flat on the base plate with the opening of the bottle cap facing upwards; then the bottle cap positioning mechanism adjusts the horizontal position of the bottle cap on the base plate to position the horizontal position of the bottle cap to correspond with the gasket installation mechanism; then the gasket installation mechanism installs the gasket in the bottle cap.
[0005] However, during the actual assembly process, although the horizontal position of the bottle cap on the base plate can be adjusted by the bottle cap positioning mechanism, the bottom surface of the bottle cap may partially detach from the top surface of the base plate during the adjustment process. That is, after the positioning is adjusted, the bottle cap may be slightly tilted and raised.

[0017] Preferably, the telescopic cylinder is a hydraulic cylinder.
[0018] Preferably, the telescopic cylinder is an electric cylinder.
[0019] The advantages and beneficial effects of this utility model are as follows: It provides a bottle cap gasket assembly device, which can install the gasket in the bottle cap; and before installing the gasket, it can adjust the horizontal position of the bottle cap on the positioning base plate and prevent the bottle cap from tilting or lifting, so that the bottom surface of the bottle cap is reliably flat with the top surface of the base plate, thereby improving the installation accuracy of the gasket and increasing the production yield; and during the process of adjusting the positioning bottle cap, a pair of springs can buffer the downward movement of the lifting sleeve to avoid damage to the bottle cap caused by the lifting sleeve moving too fast.

[0021] Figure 2 This is a schematic diagram of the bottle cap gasket assembly device when the bottle cap on the base plate has been adjusted and positioned. Detailed Implementation
[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0023] The specific technical solution of this utility model is as follows:
[0024] like Figure 1 and Figure 2 As shown, a bottle cap gasket assembly device includes: a base plate 1 for laying the bottle cap 41 flat, a bottle cap positioning mechanism 2 for positioning the bottle cap 41 on the base plate 1, and a gasket mounting mechanism 3 for installing the gasket 42 in the bottle cap 41.
[0025] The bottle cap positioning mechanism 2 includes: a vertical lifting sleeve 21 located directly below the gasket mounting mechanism 3 and above the base plate 1; a vertical guide sleeve 22 located in the middle of the lifting sleeve 21 and fixed to the outer ring of the lifting sleeve 21; a pair of vertical lifting rods 23 passing through the base plate 1 and fixed to the bottom end of the lifting sleeve 21 at their top; a flat lifting plate 24 located below the base plate 1 and fixed to the bottom end of the pair of lifting rods 23 at their top surface; a vertical telescopic cylinder 25 fixed to the base plate 1 and the lifting plate 24 at both ends; and a pair of vertical springs 26 respectively fitted on each lifting rod 23, fixed to the bottom end of the lifting sleeve 21 at their top and to the top surface of the base plate 1 at their bottom.
[0026] The outer diameter of the guide sleeve 22 is larger than the outer diameter of the bottle cap 41, and the inner diameter of the guide sleeve 22 is equal to the inner diameter of the bottle cap 41. The bottom end of the guide sleeve 22 is provided with an annular chamfer 27, which is coaxial with the guide sleeve 22. The annular chamfer 27 extends from the inner circle to the outer circle of the guide sleeve 22, and the inner part of the annular chamfer 27 is higher than the outer part.
[0027] The guide sleeve 22 and the lifting sleeve 21 are coaxial; the pair of lifting rods 23 are symmetrically arranged with respect to the axis of the lifting sleeve 21; the pair of springs 26 are symmetrically arranged; the lifting plate 24 and the lifting sleeve 21 are coaxial; the telescopic cylinder 25 and the lifting sleeve 21 are coaxial.
[0028] The telescopic cylinder 25 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0029] The working principle of this bottle cap gasket assembly device includes:
[0030] During assembly, first place the bottle cap 41, which requires the installation of the gasket 42, flat on the base plate 1, with the opening of the bottle cap 41 facing upwards and the bottle cap 41 positioned directly below the guide sleeve 22.
[0031] Then the bottle cap positioning mechanism 2 works. Specifically, the telescopic cylinder 25 drives the lifting plate 24 to move down. The lifting plate 24 drives the lifting sleeve 21 to move down synchronously through a pair of lifting rods 23. The lifting sleeve 21 drives the guide sleeve 22 to move down synchronously. During the downward movement of the guide sleeve 22, the annular chamfer 27 at the bottom of the guide sleeve 22 contacts the top of the bottle cap 41. The annular chamfer 27 can gradually adjust the horizontal position of the bottle cap 41 on the base plate 1, positioning the horizontal position of the bottle cap 41 to be coaxial with the guide sleeve 22 / lifting sleeve 21. At this time, the horizontal position of the bottle cap 41 corresponds to the gasket mounting mechanism 3. Since the annular chamfer 27 presses down on the top of the bottle cap 41, it can prevent the bottle cap 41 from tilting and lifting up, so that the bottom surface of the bottle cap 41 is reliably flat with the top surface of the base plate 1. During the downward movement of the lifting sleeve 21, a pair of springs 26 are compressed. The pair of springs 26 can buffer the downward movement of the lifting sleeve 21 and avoid damage to the bottle cap 41 due to the lifting sleeve 21 moving down too fast.
[0032] Then the gasket mounting mechanism 3 moves down to install the gasket 42 in the bottle cap 41 (the gasket 42 on the gasket mounting mechanism 3 is coaxial with the lifting sleeve 21), and the gasket mounting mechanism 3 moves up to reset after completing its work; since the gasket mounting mechanism 3 is existing technology, the specific structure and working principle of the gasket mounting mechanism 3 will not be described in detail in this utility model.
[0033] Then the bottle cap positioning mechanism 2 is reset. Specifically, the telescopic cylinder 25 drives the lifting plate 24 to move upward. The lifting plate 24 drives the lifting sleeve 21 to move upward synchronously through a pair of lifting rods 23. The lifting sleeve 21 drives the guide sleeve 22 to move upward synchronously. The guide sleeve 22 moves upward and disengages from the bottle cap 41 until the lifting sleeve 21 and the guide sleeve 22 move upward and are fully reset.
[0034] After both the gasket installation mechanism 3 and the bottle cap positioning mechanism 2 have been reset, the bottle cap 41, which has completed the installation of the gasket 42, will be removed.
[0035] As can be seen from the above, the bottle cap gasket assembly device of this utility model can install the gasket 42 in the bottle cap 41; and can adjust the horizontal position of the bottle cap 41 on the positioning base plate 1 before installing the gasket 42, and prevent the bottle cap 41 from tilting and lifting, so that the bottom surface of the bottle cap 41 is reliably flat with the top surface of the base plate 1, thereby improving the installation accuracy of the gasket 42 and increasing the yield; and can also buffer the downward movement of the lifting sleeve 21 by a pair of springs 26 during the adjustment of the positioning bottle cap 41, so as to avoid damage to the bottle cap 41 caused by the lifting sleeve 21 moving too fast.
[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
