Description

Technical Field

[0001] The utility model relates to a binocular side-view measurement module, belonging to the field of industrial endoscope measurement lenses. Background Art

[0002] Binocular measurement is used in the field of industrial endoscopes. That is, there are two objective lenses on the measuring lens (simulating human binocular imaging). According to the known distance between the two objective lenses and the change in the vertex angle formed with the measuring point, the distance between the measuring point and the lens is determined based on the principle of triangular geometry, and the measuring points of the two objective lens images are matched, and then the coordinates of the measuring point are calculated to perform dimensional measurement in various modes.

[0003] At present, binocular measurement lenses are all set at the top of the lens module, that is, they are all in direct view; in this case, the wires only need to be directly inserted vertically, and a lighting lamp will be set on the lens module, and the lighting lamp line is also installed straight; however, for a small space, the direct view lens module itself has a certain length, and the turning will be limited at this length; therefore, a visual measurement is developed to install the lens on the side of the lens module, so as to avoid the situation where the lens module is too long and cannot be photographed.

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] See also Figure 1-4 This is an embodiment of a binocular side-view measurement module of the utility model.

[0025] It includes a shell 1, a lens module 2 and a lighting module 3 arranged in the shell 1; the lens module 2 includes a circuit board 21 and a camera 22 arranged on the circuit board 21, and the lighting module 3 is a lighting optical fiber; the shell 1 includes a mounting shell 4 and a protective shell 5, and the mounting shell 4 is provided with a first side hole 6 for installing the camera 22 and a second side hole 7 for installing the lighting optical fiber.

[0026] The device contains the lens assembly of an industrial endoscope, and its purpose is to facilitate shooting in a small space and to facilitate operation by workers. In order to allow the camera 22 to shoot in a very small space, the device adopts a binocular side-viewing method. Compared with the direct-viewing camera 22, this method can have a larger operating space. Specifically, a first side hole 6 is opened on the mounting shell 4, and then the camera 22 is set in the first side hole 6. At this time, the diameter of the shell 1 is much smaller than the length of the shell 1, thereby providing a larger shooting space for the camera 22.

[0027] At the same time, in order to provide the camera 22 with better lighting conditions, a light source is provided. The lighting module 3 used in the device is a lighting optical fiber. This light source has a long service life of up to twenty years. At the same time, it is transmitted by optical fiber, so the wavelength emitted by the light source is filtered, and the light emitted is more stable. In addition, due to the characteristics of optical fiber, the lighting module 3 can be made into a very small size.

[0028] However, one drawback of optical fiber is that it should be kept as straight as possible and frequent bending should be reduced, because the bent parts will cause loss of the optical fiber. In this device, since the camera 22 is installed on the side, the end of the optical fiber should also be installed on the side, so that the optical fiber will inevitably bend. Although this will cause loss of the optical fiber, it can allow the camera 22 to work in a smaller space. Generally speaking, the advantages are greater.

[0029] However, since a part of the optical fiber itself is bent, in order to avoid other unnecessary bending of the optical fiber when in use, the device is provided with a support column 8, and an arc-shaped placement plate 9 is provided on the upper end of the support column 8; after the optical fiber is set, the arc-shaped placement plate 9 is used to support the optical fiber to prevent the optical fiber from falling and to limit the optical fiber.

[0030] At the same time, a protective shell 5 is also provided in the device. The protective shell 5 covers the outside of the entire device, and its purpose is to provide protection for the lens module 2 and the lighting module 3; the protective shell 5 is a cylindrical shell. When the protective shell 5 is installed, there is a certain gap between the cylindrical shell and the upper side of the optical fiber. When the optical fiber is deformed, the optical fiber will touch the protective shell 5 to prevent the optical fiber from deforming.

[0031] A fixing column 10 is also provided on the mounting shell 4, and the circuit board 21 is bonded to the fixing column 10 by UV glue. The fixing column 10 includes a first mounting column 11 arranged at one end of the mounting shell 4 and a second mounting column 12 arranged at the other end of the mounting shell 4, and the first side hole 6 is arranged between the first mounting column 11 and the second mounting column 12.

[0032] The first mounting post 11 and the second mounting post 12 of the device are mainly used to facilitate the fixation of the circuit board 21 and to reserve installation space for arranging the camera 22 .

[0033] The second side hole 7 is arranged at the front and rear of the first side hole 6 .

[0034] The second side hole 7 is arranged at a position that can provide equal lighting conditions for the two cameras 22 .

[0035] A stainless steel shell is arranged outside the illumination optical fiber, and the stainless steel shell is connected to the second side hole 7 by gluing.

[0036] The camera 22 is connected to the first side hole 6 by gluing, and a gluing gap between the camera 22 and the first side hole 6 is filled with waterproof glue.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
