Description

Technical Field

[0001] This invention relates to the field of optical transparent component edge sealing area inspection technology, and particularly to a windshield and cockpit canopy glass edge adhesive bonding quality inspection instrument. Background Technology

[0002] A prism is a polyhedron made of acrylic sheet, widely used in optical instruments, with applications spanning physics experiments, medical correction, and industrial instruments. During the manufacturing process of aircraft windshields and canopies, a polyester ribbon needs to be bonded to the edge of the glass to achieve a flexible connection with the frame. The bonding quality of this polyester ribbon is a key factor determining the reliability and safety of the flexible connection between the glass and the frame; therefore, the bonding quality of the polyester ribbon needs to be inspected during the manufacturing process of windshields and canopies.

[0003] In existing technologies, after the windshield and canopy glass are bonded with polyester tape, a closed space is formed in the area, making the bonded surface invisible to the naked eye. Since the windshield and canopy glass are transparent, and a prism at a suitable angle is used, the bonded surface of the polyester tape can be observed. Chinese patent CN109283684A discloses a design method and prism for observing the closed area of ​​a transparent component's edge based on Light tools simulation. This prism can assist inspectors in checking the bonding quality of the bonded surface using Light tools simulation. However, this device adds a software system, making it complex and requiring connection to the device and power supply, resulting in cumbersome operation. Especially when the onboard or outdoor environment does not meet the requirements, it may become unusable.

[0004] To improve production and inspection efficiency and enable the inspection of the adhesive quality of polyester ribbon at any time in any environment, such as on an aircraft or in the field, there is an urgent need to design a simple and practical instrument for inspecting the adhesive quality of the sealed area of ​​the edge of aircraft windshields and cockpit canopies. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quality inspection instrument for the adhesive bonding of windshield and cockpit canopy glass edges.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quality inspection instrument for the adhesive bonding of windshield and canopy glass edges includes a prism. A spherical hinge is rotatably mounted at one end of the prism. A light source is installed at the end of the spherical hinge away from the prism. A limiting mechanism for limiting the prism is provided at the end of the prism close to the spherical hinge.

[0008] Preferably, one side of the outer wall of the prism is an inclined plane with an inclination angle of 65 degrees.

[0009] Preferably, the limiting mechanism includes a fixed pressure plate, which is threadedly connected to one end of the triangular prism by four bolts.

[0010] Preferably, the fixed pressure plate has a circular hole inside for one end of the light source to pass through, and one end of the prism has a circular groove for the spherical hinge to rotate and adjust inside it.

[0011] Preferably, the end of the spherical hinge away from the prism has a socket, and the lamp head of the light source passes through the round hole and is inserted into the socket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The adhesive bonding quality inspection instrument for the edge sealing area of ​​aircraft windshields and cockpit canopies designed in this utility model can inspect the adhesive bonding quality of the edge sealing area of ​​windshields and cockpit canopies under any environmental conditions such as on an aircraft, in a laboratory, or in an outdoor field; and the instrument has a simple structure, small size, is easy to carry, has a wide range of applications, high flexibility, and can be standardized for production.

[0014] 2. The prism designed in this utility model has a length of 95mm, a width of 50mm, a height of 60mm, and an angle of 65° between the inclined surface and the bottom surface, which can maximize the observation of the adhesive surface in the closed area.

[0015] 3. The light source of this utility model is designed as a rotatable integrated prism light source, which makes it convenient for the observer to change the light. It can avoid the problem of insufficient light in the visible area during inspection, and at the same time frees up one hand, solving the problem of holding the light source in one hand and the prism in the other.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A quality inspection instrument for the adhesive bonding of windshield and canopy glass edges includes a prism 1. A spherical hinge 4 is rotatably mounted at one end of the prism 1. A light source 3 is mounted at the end of the spherical hinge 4 away from the prism 1. A limiting mechanism is provided at the end of the prism 1 near the spherical hinge 4 to limit its movement. The prism 1 is made of acrylic sheet material commonly used in the prior art. The light source 3 is a small, high-intensity flashlight commonly used in the prior art. The strong light generated by the light source 3 shines into the adhesive bonding surface of the closed edge area of ​​the glass body 9, and the quality of the adhesive bonding surface is inspected by the reflected light.

[0024] As a technical optimization in this utility model, one outer wall of the prism 1 is a slope with an inclination angle of 65 degrees. Since the refractive index of the acrylic sheet material is approximately 1.49, and the range of the closed area at the edge of the glass is 18mm-23mm, the final dimensions of the prism 1 in this embodiment are calculated to be 95mm in length, 50mm in width, 60mm in height, and the angle between the slope and the bottom surface is 65°, thus maximizing the observation angle of the prism 1 over the adhesive surface of the closed area at the edge of the glass body 9.

[0025] As a technical optimization of this utility model, the limiting mechanism includes a fixed pressure plate 2, which is threadedly connected to one end of the triangular prism 1 by four bolts 5.

[0026] As a technical optimization of this utility model, the fixed pressure plate 2 has a circular hole 11 for one end of the light source 3 to pass through, and the triangular prism 1 has a circular groove 10 for the spherical hinge 4 to rotate and adjust inside it.

[0027] As a technical optimization of this utility model, the end of the spherical hinge 4 away from the triangular prism 1 is provided with a socket 12, and the lamp head of the light source 3 is inserted into the socket 12 after passing through the round hole 11. When installing the spherical hinge 4 and the triangular prism 1, first place the spherical hinge 4 inside the circular groove 10, then align the fixing plate 2 with one end of the triangular prism 1, and then sequentially screw multiple first bolts 5 through the fixing plate 2 into the interior of the triangular prism 1 to achieve the purpose of installing the fixing plate 2 at one end of the triangular prism 1. Since the diameter of the circular hole 11 inside the fixing plate 2 is smaller than the diameter of the spherical hinge 4, after installing the fixing plate 2 and the triangular prism 1, the spherical hinge 4 placed inside the circular groove 10 can be simultaneously limited and fixed. Since the diameter of the circular hole 11 inside the fixing plate 2 is compatible with the diameter of the light source 3, after the light source 3 is inserted through the circular hole 11 and into the insertion hole 12, the inspector can manually drive the light source 3 and the spherical hinge 4 to rotate and adjust at any angle inside the circular hole 11 and the circular groove 10. The inspector can rotate the light source 3 arbitrarily according to actual needs to make the light reach any observation position.

[0028] In this utility model, when the operator actually uses the inspection instrument to check the quality of the adhesive bonding at the glass edge, such as Figure 5 As shown, the bonding quality between the glass body 9 and the polyester ribbon 6 is inspected by visual observation. After the inspection instrument is assembled, a layer of glycerin is applied to the bottom surface of the prism 1 as a coupling agent. Then, the light source 3 of the high-intensity flashlight is inserted into the socket 12 on the spherical hinge 4. The light generated by the high-intensity flashlight is reflected and refracted between the prism 1 and the glass body 9 and finally enters the human eye, so as to achieve the effect of detecting the bonding quality between the glass body 9 and the polyester ribbon 6 in the enclosed space.

[0029] When actually using prism 1 to observe the adhesive surface of the closed area at the edge of glass, the placement position and light path propagation are as follows: Figure 4 As shown, Figure 4 The reflected light rays are at three extreme positions. Reflected light rays 1, 2, and 3 are all perpendicular to the inclined surface of prism 1. The area from reflected light 1 to reflected light 2 is the area of ​​the inner adhesive surface to be observed, and the area from reflected light 2 to reflected light 3 is the area of ​​the outer adhesive surface to be observed. The observation angle is the largest when the angle between the inclined surface and the bottom surface is 65°.

[0030] Since the light source 3 and the spherical hinge 4 can be rotated and adjusted at any angle inside the circular hole 11 and the circular groove 10, the inspector can rotate the light source 3 at will to make the light reach any observation position according to actual needs. This makes it convenient for the inspector to change the position of the light and avoids the problem of insufficient light in the visible area during inspection. At the same time, when using the inspection instrument, after adjusting the position of the light source 3, the inspector can hold the prism 1 with one hand, freeing up the inspector's other hand and thus solving the problem of holding the light source 3 with one hand and the prism 1 with the other.

[0031] At the same time, by using glycerin as a coupling agent, light can be smoothly propagated on the bonding surface. The light source 3 provides light to the closed area, ensuring that the bonding surface of the polyester ribbon 6 in the closed area of ​​the glass body 9 can be clearly observed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
