Description

Technical Field

[0001] This invention belongs to the field of mechanical device technology, specifically relating to a device and method for bonding annular copper-clad strips inside a spherical fairing. Background Technology

[0002] The spherical fairing is specifically a spherical glass fairing. It serves as the front window of a guidance-type seeker head, used for atmospheric deflection to reduce air friction; the glass construction ensures that specific types of light can be transmitted through. The annular copper-clad strip acts as a trip switch, meaning that when the spherical fairing contacts a target, it shatters under speed or impact, and the broken annular copper-clad strip detonates subsequent components. Previously, thin copper-clad strips with a specific pattern were glued onto a spherical fairing, and copper-clad strips were also plated using coating technology, but the results were unsatisfactory due to the thinness of the copper-clad strips. Later, annular copper-clad strips were glued onto the spherical fairing, but this method had problems with determining the bonding position of the annular copper-clad strip on the spherical surface and controlling the adhesive position and width.

[0003] Chinese patent document published on February 5, 2014, discloses a helicopter vertical tail. Aluminum foil is adhered to the leading edge, trailing edge, and tip of the vertical tail, centered on their respective symmetrical center lines. Aluminum foil is also adhered around the midpoint of the vertical tail surface. A metal diverter strip connects the metal interface between the vertical tail fairing and the main vertical tail structure to the tail boom metal structure. In this document, the aluminum foil may melt after multiple lightning strikes. After a lightning strike, inspecting the aluminum foil and appropriately re-adhering it can meet the lightning protection requirements. The use of copper strip diverter strips can protect against multiple lightning strikes. However, the copper strip in this document plays a different role than the copper strip in this application, and it does not solve the problems of difficulty in determining the bonding position of the annular copper-clad strip on a spherical surface, and the inability to control the adhesive position and width.

[0035] Example 1:

[0036] like Figures 1 to 3 As shown, an apparatus for bonding an annular copper-clad strip inside a spherical fairing includes a spherical fairing 3 and an annular copper-clad strip 4, and also includes a base adhesive coating apparatus 1 and a top adhesive coating apparatus 2.

[0037] The base adhesive coating device 1 includes a base 11, an upper stop block 12, a lower stop block 13, and a positioning ring 14. The outer side of the base 11 is connected to the outer side of the upper stop block 12. The upper part of the upper stop block 12 is connected to the positioning ring 14. The middle part of the positioning ring 14 is connected to the upper end of the lower stop block 13. The lower part of the inner side of the upper stop block 12 and the lower part of the lower stop block 13 are connected from top to bottom to the upper part of the spherical fairing 3. The lower part of the spherical fairing 3 is connected to the inner upper part of the base 11.

[0038] The adhesive coating device 2 includes a base 21, an upper stop block 22, a lower stop block 23, and a positioning ring 24. The outer side of the base 21 is connected to the outer side of the upper stop block 22. The upper stop block 22 is connected to the upper position of the positioning ring 24. The middle part of the positioning ring 24 is connected to the upper end of the lower stop block 23. The lower part of the upper stop block 22 and the lower part of the lower stop block 23 are connected from top to bottom to the upper part of the spherical fairing 3. The lower part of the spherical fairing 3 is connected to the upper inner side of the base 21.

[0039] The device for bonding annular copper-clad strips inside a spherical fairing provided by this invention uses a base 11, upper stop 12, lower stop 13, and positioning ring 14 in a base adhesive coating device 1 to stably fix the spherical fairing 3 inside the base adhesive coating device 1. By adjusting the distance between the upper stop 12 and the lower stop 13, precise control can be achieved over the bonding position, adhesive position, and width of the annular copper-clad strip 4. Similarly, the device uses a base 21, upper stop 22, lower stop 23, and positioning ring 24 in a top adhesive coating device 2 to stably fix the spherical fairing 3 inside the top adhesive coating device 2. By adjusting the distance between the upper stop 22 and the lower stop 23, precise control can be achieved over the bonding position, adhesive position, and width of the annular copper-clad strip 4.

[0040] Example 2:

[0041] Based on Embodiment 1, both the base 11 and the base 21 are cylindrical and have a stepped hole 11-1 opened on the central axis of the cylinder. The diameter of the stepped hole 11-1 decreases from top to bottom, and the bottom of the spherical fairing 3 is connected to the stepped surface.

[0042] The stepped hole 11-1 contacts the spherical fairing 3, providing support for the placement of the spherical fairing 3. The upper inner circle of the stepped hole 11-1 mates with the lower outer circle of the upper stop block 12, ensuring that the spherical fairing 3 and the upper stop block 12 are concentric.

[0043] Preferably, the stepped hole 11-1 has two steps. The two-step structure is simple and can meet the support requirements.

[0044] Preferably, both the upper stop block 12 and the upper stop block 22 are annular, with a recessed hole 12-1 formed on the lower part of the annulus. The upper end of the spherical fairing 3 is connected to the recessed hole 12-1. This allows the spherical fairing 3 to be stably held in place, facilitating the application of adhesive.

[0045] Preferably, the spherical fairing 3, base 11, upper stop 12, lower stop 13, and positioning ring 14 are concentric, which facilitates precise control over the adhesive bonding position and width of the annular copper-clad strip 4.

[0046] Preferably, the inner side of the concave hole 12-1 is an acute angle.

[0047] The acute-angled edge contacts the upper surface of the spherical fairing 3, increasing the contact area of ​​the connection, improving the connection stability, and increasing the space for adhesive application.

[0048] Preferably, the upper end of the upper stop block 12 is connected to the inner circle of the positioning ring 4; that is, the upper stop block 12 is locked inside the base 11 and the positioning ring 4, and this connection has good stability.

[0049] Preferably, the lower block 13 includes an upper connecting rod 13-1 and a lower connecting block 13-2, with the center of the lower connecting block 13-2 passing through an upper connecting positioning ring 14 on the upper connecting rod 13-1;

[0050] Each of the lower blocks 23 includes an upper connecting rod 23-1 and a lower connecting block 23-2, with the center of the lower connecting block 23-2 connected to the upper connecting rod 23-1 via a positioning ring 14.

[0051] This structure ensures that the lower stop block 13 and the positioning ring 14 are concentric, and the lower stop block 23 and the positioning ring 24 are concentric.

[0052] Preferably, both the lower connecting block 13-2 and the lower connecting block 23-2 are cylindrical and protrude outward and upward in the circumferential direction.

[0053] This structure ensures that the upper and lower edges of the lower connecting block 13-2 fully fit the upper surface of the spherical fairing 3, preventing adhesive leakage during application.

[0054] Preferably, both the positioning ring 14 and the positioning ring 24 are circular rings. The center of the positioning ring 14 is provided with a positioning hole 14-1, and the upper end of the upper connecting rod 13-1 is connected to the positioning hole 14-1. The center of the positioning ring 24 is provided with a positioning hole 24-1, and the upper end of the upper connecting rod 23-1 is connected to the positioning hole 24-1.

[0055] Positioning hole 14-1 ensures that lower stop block 13 and positioning ring 14 are concentric, and positioning hole 24-1 ensures that lower stop block 23 and positioning ring 24 are concentric.

[0056] Preferably, the longitudinal section of the protrusion is an acute triangle.

[0057] The acute angle tip contacts the upper surface of the spherical fairing 3, which serves as a limiting connection while reducing weight and increasing the space for adhesive application.

[0058] Preferably, the upper diameter of the lower connecting block 13-2 is larger than the upper diameter of the lower connecting block 23-2, and the lower diameter of the lower connecting block 13-2 is larger than the lower diameter of the lower connecting block 23-2.

[0059] This structure ensures that the contact position between the lower connecting block 13-2 and the upper surface of the spherical fairing 3 is higher than that between the lower connecting block 23-2 and the upper surface of the spherical fairing 3, so that the width of the top adhesive coating area is greater than that of the bottom adhesive coating area; ensuring that the top adhesive application range completely covers the annular copper-clad strip, and increasing the bonding quality between the annular copper-clad strip and the spherical fairing 3.

[0060] Preferably, the distance between the lower edge of the inner side of the concave hole 12-1 in the upper stop block 12 and the upper edge of the lower connecting block 13-2 is less than the width of the annular copper-clad strip 4.

[0061] Ensure that the area covered by the base coat does not affect the optical window of the spherical glass radome.

[0062] Preferably, the distance between the lower edge of the inner side of the concave hole 12-1 in the upper stop block 22 and the upper edge of the lower connecting block 23-2 is greater than the width of the annular copper-clad strip 4.

[0063] Ensure the adhesive application area completely covers the annular copper-clad strip 4 to improve the bonding quality between the annular copper-clad strip 4 and the spherical glass shroud. The coverage area of ​​the adhesive can be controlled by adjusting the distance between the lower edge of the inner side of the recess 12-1 in the upper stop block 22 and the upper edge of the lower connecting block 23-2, i.e., by controlling the outer diameter of the lower connecting block 23-2. With the position of the recess 12-1 in the upper stop block 22 unchanged, the larger the outer diameter of the lower connecting block 23-2, the smaller the coverage area of ​​the adhesive.

[0064] Preferably, a protective layer 11-2 is provided on the step surface, and the protective layer 11-2 is connected to the bottom of the spherical fairing 3.

[0065] Specifically, the spherical fairing 3 is a spherical glass fairing; a protective layer 11-2 is used to protect the surface of the spherical fairing 3.

[0066] Preferably, the protective layer 11-2 is made of cloth; the cloth includes fleece, velvet, and other materials, but other materials can also be selected to protect the surface of the spherical fairing 3. Specifically, the cloth is adhered to the step surface.

[0067] Preferably, the base 11 and base 21 have the same structure and dimensions, and the positioning ring 14 and positioning ring 24 have the same structure and dimensions. That is, the base 11 and base 21 are interchangeable, and the positioning ring 14 and positioning ring 24 are interchangeable, which is highly practical.

[0068] Preferably, the upper part of the inner side of the upper stop block 12 is inclined and the lower part is vertical. After applying the adhesive, when the annular copper-clad strip 4 is placed from top to bottom, the vertical surface plays a limiting role, making it easier for the annular copper-clad strip 4 to be placed in the target position.

[0069] Preferably, the inner surface of the upper stop block 22 is inclined. This facilitates the positioning of the annular copper-clad strip 4 and the spherical fairing 3 that are attached.

[0070] Example 3:

[0071] Based on Example 2, such as Figure 4 As shown, a method of using an apparatus for bonding an annular copper-clad strip inside a spherical fairing, based on any one of the claims, includes the following steps:

[0072] 1) The spherical fairing 3 is connected inside the base coat applicator 1, and the area above the spherical fairing 3 between the upper baffle 12 and the lower baffle 13 is the base coat applicator area.

[0073] Specifically, the method for connecting the spherical fairing 3 to the base coating device 1 is as follows: the spherical fairing 3 is placed in the base 11, and the spherical fairing 3 is fixed by the upper stop block 12 and the lower stop block 13, and the positioning ring 14 limits the lower stop block 13.

[0074] 2) Apply primer evenly to the primer application area;

[0075] 3) Align the upper edge of the annular copper-clad strip 4 with the lower edge of the upper stop block 12, and align the lower edge of the annular copper-clad strip 4 with the upper edge of the lower stop block 13, then place the annular copper-clad strip 4 on the coated base adhesive.

[0076] 4) Remove the upper stop block 12 and the lower stop block 13, and cure the spherical fairing 3 with the annular copper-clad strip 4 attached.

[0077] Specifically, during curing, the product is irradiated under an ultraviolet lamp for no less than 60 seconds.

[0078] 5) Connect the spherical rectifier 3 with the annular copper-clad strip 4 after curing to the adhesive coating device 2. The area between the upper block 22 and the lower block 23 is the adhesive coating area, and the annular copper-clad strip 4 is located in the adhesive coating area.

[0079] 6) Apply a uniform coating of adhesive to the surface of the annular copper-clad strip 4;

[0080] 7) Take out the upper baffle 22, the lower baffle 23 and the spherical rectifier 3 with the annular copper-clad strip 4 attached and coated with adhesive. After drying the spherical rectifier 3 with the annular copper-clad strip 4 attached and coated with adhesive, the bonding of the annular copper-clad strip 4 to the spherical rectifier 3 is completed.

[0081] Specifically, the method for drying the spherical rectifier 3 with the annular copper-clad strip 4 coated with adhesive is as follows: after the adhesive is applied, let it air dry at room temperature for no less than 30 minutes, and then dry it at (50-60)℃ for no less than 3 hours.

[0082] Applying topcoat or basecoat can be done with a brush or other methods.

[0083] The method of using the apparatus for bonding annular copper-clad strips inside a spherical fairing according to the present invention achieves precise control of the adhesive application position and area through an adhesive coating device. The bonding of the annular copper-clad strip to the inner surface of the spherical glass is achieved stepwise through bottom adhesive coating, annular copper-clad strip arrangement, and top adhesive coating. While effectively preventing free flow of the adhesive, the bonding quality of the annular copper-clad strip is improved, ensuring the consistency of the bonding of the annular copper-clad strip on the inner surface of the spherical glass fairing.
