Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a sealing ring adhesive backing fixture. Background Technology

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases. It is usually made of elastic material and has a sealing function. Some sealing rings on the market require an adhesive backing to be applied during production. When using the sealing ring, the release paper on the adhesive backing is peeled off before it is pasted on. The adhesive backing helps to fix the sealing ring in place and prevent it from shifting.

[0003] Applying adhesive to sealing rings is typically done using an adhesive application fixture. During application, the sealing ring is placed into a contoured groove, the adhesive is placed on the sealing ring, and then the adhesive and sealing ring are pressed together to complete the application. Air must usually be expelled from the contoured groove during application to ensure quality. Sealing ring adhesive application is often done in large batches, therefore the fixture will have many contoured grooves. Because of the large number of contoured grooves on the fixture, and the lack of mutual venting structures between them, significant resistance may occur when the fixture closes, resulting in uneven force distribution and affecting the quality of the adhesive application.

[0004] For example, Chinese Patent Application No. CN201921086157.5 discloses an adhesive-backing fixture, characterized by comprising: a base plate, wherein the base plate has at least one positioning structure suitable for positioning the product to be adhesive-backed; and a cover plate, wherein the cover plate has through holes at corresponding positions on the product to which adhesive is to be applied, the shape and size of the through holes being adapted to the shape and size of the adhesive. This type of base plate has numerous grooves, suitable for the product to be fitted into these grooves. However, the lack of mutual venting structures between these numerous grooves may result in significant resistance when the fixture closes, leading to uneven force distribution and affecting the quality of the adhesive application.

[0005] For example, Chinese patent application number CN201720724853.9 discloses a fixture for applying adhesive backing to a mobile phone lens protector, specifically stating that "a fixture for applying adhesive backing to a mobile phone lens protector, characterized in that: it includes a base plate with a protector placement slot, and a cover plate that cooperates with the base plate; the cover plate is provided with a positioning bolt, and the base plate is provided with a positioning hole that cooperates with the positioning bolt." The lack of mutual venting structures between the numerous placement slots may lead to significant resistance when the fixture closes, resulting in uneven force distribution and affecting the quality of the adhesive application.

[0031] The contour grooves 21 are connected by a connecting groove 24, and the contour grooves 21 are also provided with an exhaust groove 23. Therefore, when the fixture is closed, the gas in the contour grooves 21 can be discharged in time, and there is no closing resistance, which helps to ensure the quality of the adhesive backing.

[0032] This application provides a sealing ring adhesive backing fixture, including a base plate 20 and a cover plate 10. The cover plate 10 is hinged to the base plate 20 and can cover the base plate 20. The base plate 20 is provided with a contour groove 21, an exhaust groove 23, a connecting groove 24, and a positioning hole 25. The connecting groove 24 connects to the contour groove 21. The exhaust groove 23 connects to the contour groove 21, and gas in the contour groove 21 can be discharged through the exhaust groove 23. The sealing ring 30 is placed in the contour groove 21. The cover plate 10 is provided with a contour block 11, a positioning post 13, and a handle 14. The contour block 11 can press on the adhesive backing of the sealing ring 30, and the positioning post 13 passes through the positioning hole 25. There are several contour grooves 21, which are arranged in a matrix on the base plate 20. A boss 22 is provided in the contour groove 21. During operation, the worker places the sealing ring 30 into the contour groove 21, then aligns the adhesive backing sleeve protrusion 22 with the sealing ring 30. Next, the worker closes the cover plate 10 onto the base plate 20. The contour block 11 presses against the adhesive backing, allowing gas in the contour groove 21 to circulate through the connecting groove 24 and exit through the venting groove 23. This ensures a smooth and unobstructed closure between the base plate 20 and the cover plate 10, with each sealing ring 30 experiencing uniform force, thus contributing to the quality of the adhesive application. The positioning post 13, inserted into the positioning hole 25, ensures the closure accuracy of the base plate 20 and the cover plate 10. The handle 14 facilitates manual operation of the closing fixture. In this embodiment, the venting groove 23 is connected to the outermost contour groove 21, allowing gas in the inner contour groove 21 to exit through the outer contour groove 21. Connecting grooves 24 connect adjacent contour grooves 21, resulting in smoother venting and faster pressure equalization.

[0033] The depth of the exhaust groove 23 and the connecting groove 24 is greater than the depth of the contour groove 21. This design ensures that the air in the contour groove 21 is not obstructed by the sealing ring 30, allowing for smoother gas flow. There are three positioning posts 13 and three positioning holes 25, arranged in a triangular pattern, allowing the top plate and bottom plate 20 to close precisely.

[0034] Example 2

[0035] Please refer to Figure 2-5 As shown, the structure of Embodiment 2 is largely the same as that of Embodiment 1. The specific working principle will not be repeated here. The main differences are as follows.

[0036] The cover plate 10 is provided with a first wiring groove 15, and the contour block 11 is provided with a first heating element 12. The first wire 110 in the first wiring groove 15 is connected to the first heating element 12. The first heating element 12 is preferably a metal electric heating element.
