A shell tip detection mechanism

Abstract

This utility model discloses a projectile tip detection mechanism, relating to the field of projectile detection. The projectile tip detection mechanism includes a photographing unit and a moving unit: the photographing unit is disposed on the side of the projectile transport frame, and includes a base and a supplementary lighting component. A support is mounted on top of the base, and a CCD camera is mounted on the top of the support. The supplementary lighting component includes a supplementary lighting box, which is mounted on the side of the support end. A supplementary lighting lamp is embedded at the bottom of the supplementary lighting box, and the supplementary lighting box has a through-hole. A double-sided mirror is installed at an angle inside the supplementary lighting cavity. The moving unit is disposed at the bottom of the photographing unit. In this projectile tip detection mechanism, when light is shone into the supplementary lighting cavity by the supplementary lighting lamp, the light comes into contact with the double-sided mirror, causing the light to be reflected horizontally outward, thus allowing the reflected light to illuminate the tip of the projectile, providing an effective supplementary lighting effect.

Description

Technical Field

[0001] The utility model relates to the technical field of shell detection, in particular to a shell end detection mechanism. Background Art

[0002] In industrialized production, some errors are inevitable, which lead to poor appearance during the production process. Functional defects can be identified through functional testing.

[0003] In the process of inspecting artillery shells, it is generally necessary to place the artillery shells on a conveyor belt, and then pass through various inspection stations during the transportation of the artillery shells. The artillery shells are generally placed horizontally on the conveyor belt. When it is necessary to take pictures of the end of the artillery shell for inspection, it is necessary to set a horizontal CCD camera to aim at the end of the artillery shell. However, the inner wall of the end of the artillery shell is generally difficult to light, thereby reducing the photo quality of the CCD camera. Because the diameter of the end of the artillery shell is small, even if an inclined lighting lamp is set, it is not easy to shine the light into the inner wall of the end of the artillery shell. Therefore, we propose a artillery shell end detection mechanism. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides a shell tip detection mechanism, which solves the problem that the inner wall of the shell tip is generally difficult to light, thereby reducing the photographing quality of the CCD camera 102. Since the diameter of the shell tip is small, even if an inclined lighting lamp is set, it is not easy to illuminate the inner wall of the shell tip. By using the double-sided mirror 203 installed inside the fill light cavity 202, when the fill light lamp 201 embedded at the bottom of the fill light box 2 injects light into the fill light cavity 202, the light contacts the double-sided mirror 203, so that the light is reflected by the double-sided mirror 203, so that the reflected light is horizontally irradiated outward, and then the reflected light is illuminated into the shell tip, which has an effective fill light effect on the shell tip. At the same time, through the structural characteristics of the double-sided mirror 203, the CCD camera 102 at the top of the support seat 101 can take pictures of the shell tip through the double-sided mirror 203, achieving an effective photographing effect.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a shell tip detection mechanism.

[0027] According to the attached Figure 1-4 As shown, including:

[0028] The photographing unit is arranged on the side of the shell conveying rack, and the photographing unit includes:

[0029] A base 1, a support base 101 is installed on the top of the base 1, and a CCD camera 102 is installed on the top of the support base 101;

[0030] A fill light assembly, the fill light assembly includes a fill light box 2, the fill light box 2 is mounted on the side of the end of the support seat 101, a fill light lamp 201 is embedded at the bottom of the fill light box 2, and the fill light lamp 201 provides fill light to the end of the shell above the conveyor frame;

[0031] The fill light box 2 is provided with a through fill light cavity 202 , and a double-sided mirror 203 is obliquely arranged inside the fill light cavity 202 . The double-sided mirror 203 can reflect the illumination light of the fill light fixture 201 , and the CCD camera 102 can take pictures of the end of the shell through the double-sided mirror 203 .

[0032] During use, using the double-sided mirror 203 installed inside the fill-light cavity 202, when the fill-light lamp 201 embedded at the bottom end of the fill-light box 2 emits light into the fill-light cavity 202, the light contacts the double-sided mirror 203, so that the light is reflected by the double-sided mirror 203, so that the reflected light is horizontally irradiated outward, and then the reflected light is illuminated into the end of the shell, which has an effective fill-light effect on the end of the shell. At the same time, through the structural characteristics of the double-sided mirror 203, the CCD camera 102 at the top of the support seat 101 can take a picture of the end of the shell through the double-sided mirror 203, thereby achieving an effective photographic effect.

[0033] The moving unit is arranged at the bottom of the photographing unit, and the moving unit is used to drive the photographing unit to move, so as to facilitate the adjustment of the distance between the photographing unit and the shell conveying rack.

[0034] Furthermore, a mounting frame 204 is fixedly connected to the side of the fill light box 2 , and the mounting frame 204 is fixedly installed above the base 1 .

[0041] Furthermore, one end of the screw rod 301 passes through the outer wall of the fixing base 3 , extends outward, and is fixedly connected to the turning handle 304 .

[0042] By setting the turning handle 304 , when the turning handle 304 is rotated, the screw rod 301 can be rotated, so that the position of the base 1 can be adjusted conveniently.
