Description

Technical Field

[0001] The utility model relates to the technical field of industrial camera lenses, in particular to an industrial camera lens used in a narrow space. Background Art

[0002] Industrial cameras are a key component in machine vision systems. Their most essential function is to convert optical signals into orderly electrical signals. Selecting a suitable camera is also an important part of machine vision system design. The camera not only directly determines the resolution and quality of the collected images, but is also directly related to the operating mode of the entire system.

[0003] In the field of industrial automation equipment, the size and space of many devices are strictly restricted. Some of the equipment is equipped with industrial cameras to form machine vision, but the structural space of the equipment is not enough to install the camera and lens components. This requires new technologies to solve the problem of the camera optical system. Utility Model Content

[0004] The purpose of the utility model is to provide an industrial camera lens for a narrow space, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial camera lens for a narrow space, comprising an industrial camera body and a main shell, a lens is fixedly installed on one side surface of the industrial camera body, a lens cavity and a reflector cavity which are connected horizontally and vertically are provided in the main shell, a shooting slot is provided on the lower end surface of the reflector cavity away from the lens cavity, the lens is limited and extended to the inside of the lens cavity, and the lens extends to the intersection of the lens cavity and the reflector cavity, a first plane reflector and a second plane reflector are respectively embedded and installed in the reflector cavity, and the first plane reflector and the second plane reflector are respectively fixedly installed at both ends of the reflector cavity, the reflector surfaces of the first plane reflector and the second plane reflector are parallel to each other, and form an angle of 45° with the central axis of the lens.

[0006] Optionally, a ring light source is installed and connected in the shooting slot.

[0007] Optionally, focusing baffles for scattering light are fixedly mounted on both side surfaces of the main shell located on the annular light source lamp.

[0008] Optionally, an elastic band is fixedly connected to one side surface of the main shell.

[0009] Optionally, a protective sealing gasket is fixedly connected to the surface of the main shell that contacts the industrial camera body.

[0010] Optionally, a first fixed slot plate is fixedly connected to both side surfaces of the main shell, a second fixed slot plate is attached to the lower surface of the first fixed slot plate, and the second fixed slot plate is fixedly connected to both side surfaces of the main shell, and the internal threads of the first fixed slot plate and the second fixed slot plate are connected by bolts.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model utilizes the light reflection principle of the first plane reflector and the second plane reflector in the reflector cavity, so that the operator can move the horizontal main shell deeper into the narrow space. As the main shell moves deeper, the shooting slot will gradually align with the position to be shot, and the object shot through the shooting slot will be sent into the lens after the light passes through the first plane reflector and the second plane reflector for two 90° turns, thereby achieving the purpose of shooting in the narrow space, avoiding the interference of the lens and the camera with other structural components of the equipment, thereby improving the flexible practicality of the industrial lens.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] For example, see Figures 1 to 3The utility model provides an industrial camera lens for a narrow space, comprising an industrial camera body 1 and a main shell 3, a lens 2 is fixedly installed on one side surface of the industrial camera body 1, a lens cavity 5 and a reflector cavity 6 which are connected horizontally and vertically are provided in the main shell 3, a shooting slot 7 is provided on the lower end surface of the reflector cavity 6 away from the lens cavity 5, the lens 2 is limited and extended to the inside of the lens cavity 5, and the lens 2 extends to the intersection of the lens cavity 5 and the reflector cavity 6, a first plane reflector 9 and a second plane reflector 10 are respectively embedded and installed in the reflector cavity 6, and the first plane reflector 9 and the second plane reflector 10 are respectively fixedly installed at both ends of the reflector cavity 6, the reflector surfaces of the first plane reflector 9 and the second plane reflector 10 are parallel to each other, and form an angle of 45° with the central axis of the lens 2.

[0019] An elastic band 4 is fixedly connected to one side surface of the main housing 3 .

[0020] More specifically, in this embodiment, the light reflection principle of the first plane reflector 9 and the second plane reflector 10 in the reflector cavity 6 is utilized so that the operator can move the horizontal main shell 3 deeper into the narrow space after holding the hand firmly through the elastic band 4. As the main shell 3 moves deeper, the shooting slot 7 will gradually align with the position to be photographed, and the object photographed through the shooting slot 7 will be sent to the lens 2 of the industrial camera body 1 for shooting after the light passes through the first plane reflector 9 and the second plane reflector 10 for two 90° turns, thereby achieving the purpose of shooting in a narrow space, avoiding interference between the lens 2 and the camera and other structural components of the equipment, thereby improving the flexible practicality of the industrial lens.

[0021] Furthermore, a ring-shaped light source lamp 11 is installed in the shooting slot 7 , and focusing baffles 12 for emitting scattered light are fixedly installed on both side surfaces of the main housing 3 located at the ring-shaped light source lamp 11 .

[0022] It is worth noting that the annular light source lamp 11 can provide light source support for a narrow shooting space, and the focusing baffle 12 can also avoid the dispersion of the light source, which is more conducive to concentrating the light source for shooting and imaging.

[0024] Furthermore, a protective sealing gasket 13 is fixedly connected to the surface of the main shell 3 that contacts the industrial camera body 1, and a first fixed groove plate 14 is fixedly connected to the two side surfaces of the main shell 3.

[0025] More specifically, in this embodiment, the industrial camera body 1 inserts the lens 2 into the interior of the lens cavity 5 until the industrial camera body 1 contacts the protective sealing gasket 13. The protective sealing gasket 13 not only provides a buffer for the industrial camera body 1, but also avoids light leakage during shooting. At the same time, the first fixed groove plate 14 and the second fixed groove plate 15 contact each other, and finally the bolts 16 are used for threaded connection.
