Description

Technical Field

[0001] The utility model relates to the field of camera protection equipment, in particular to a moisture-proof and heat-insulating outer jacket for a camera. Background Art

[0002] In modern industry, vision inspection systems play an important role in non-contact measurement technology. For example, when scanning profiles, they are used to measure dimensions, detect surface defects, and detect bending and twisting. These applications require cameras with high precision and reliability.

[0003] However, in actual applications, cameras generate heat during operation, especially when running for a long time or in a harsh external environment. This heat will cause the ambient temperature difference, which will in turn generate condensation on the internal and external surfaces of the camera. The presence of condensation will cause circuit board corrosion, which will not only affect the performance of the camera, but also significantly shorten its service life. Therefore, an effective protection structure is needed to meet this challenge.

[0004] Current solutions on the market usually involve complex structural designs to prevent condensation from damaging the camera. These solutions are not only costly to install and maintain, but also tend to increase the overall size and weight of the camera system, which may be unacceptable in some applications. Therefore, developing a simple and economical protective structure to effectively prevent condensation from forming and improve the reliability and life of the camera in visual inspection applications has become an urgent need in this field.

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] Example 1: Reference Figure 1 , Figure 1 The utility model is a schematic diagram of the basic structure of the moisture-proof heat-insulating jacket for a camera, comprising a camera 1, a moisture-proof heat-insulating jacket 2 and a semiconductor cooling sheet 3. The moisture-proof heat-insulating jacket 2 tightly wraps the camera 1 without leaving any gaps, wherein a through hole 201 is opened on the surface of the moisture-proof heat-insulating jacket 2, and the semiconductor cooling sheet 3 is connected to the through hole 201 and is fixed closely to the surface of the camera 1 to form a closed structure, wherein the end close to the camera 1 is the cold end of the semiconductor cooling sheet 3, and the hot end thereof is arranged to face outwards. A preferred structure can open a plurality of through holes 201 on the surface of the moisture-proof heat-insulating jacket 2, and the inner periphery of each through hole 201 is inner A semiconductor cooling sheet 3 is connected; a preferred material of the moisture-proof and heat-insulating jacket 2 is heat-insulating rubber, and the thickness of the rubber is preferably 10mm-30mm. The advantage of using rubber is that it has insulating properties and a certain elasticity. During the installation process, the close fit with the camera is higher and it is not easy to produce gas residue. Under the preferred environment, the assembly process is a vacuum assembly state; the rubber material can be natural rubber, chloroprene rubber, silicone rubber, polyurethane rubber or styrene-butadiene rubber; considering the complex factory environment and the fact that the rubber itself may be easily deformed, reference Figure 2 , Figure 2 2 is a schematic diagram of the structure of the moisture-proof heat-insulating outer hoop of the camera of the utility model. Compared with the above structure, at least one hoop 204 is fixedly sleeved on the outer surface of the moisture-proof heat-insulating outer jacket 2. The hoop 204 can have a fixed inner diameter or an adjustable inner diameter. The main function of the hoop 204 is to limit the deformation of the moisture-proof heat-insulating outer jacket 2 to ensure that the moisture-proof heat-insulating outer jacket 2 can maintain a close connection with the camera 1 during long-term work to avoid condensation caused by air flowing into the interior; refer to Figure 3 , Figure 31 is a schematic cross-sectional view of the interlayer between the camera 1 and the moisture-proof heat-insulating jacket. In the figure, a vacuum desiccant 101 is provided in the interlayer between the camera 1 and the moisture-proof heat-insulating jacket 2. The vacuum desiccant 101 is used to continuously absorb the fluid that may be generated in the interlayer after the assembly is completed, so as to maintain the vacuum environment for as long as possible. Figure 4 , Figure 4 It is a schematic diagram of the structure of the shockproof, moisture-proof and heat-insulating jacket of the utility model. On the basis of the above structure, the utility model is provided with a shockproof structure 5 on at least any one side of the moisture-proof and heat-insulating jacket 2. The shockproof structure 5 is used to buffer the vibration that may be caused by the external environment to the moisture-proof and heat-insulating jacket 2, thereby optimizing the effect of the camera 1 in capturing images.

[0028] refer to Figure 5 , Figure 5 It is a schematic structural diagram of a moisture-proof and heat-insulating jacket for a camera with heat dissipation according to the utility model. On the basis of Example 1, a heat dissipation fan 4 is provided on the semiconductor cooling sheet 3 to dissipate heat for the hot end of the semiconductor cooling sheet 3.

[0029] refer to Figure 6 , Figure 6 It is a schematic diagram of the structure of the moisture-proof and heat-insulating jacket with air vent for the camera of the utility model. On the basis of the above-mentioned embodiment, a through hole 202 is further provided on the surface of the moisture-proof and heat-insulating jacket 2. The through hole 202 can be connected to a vacuum pump to evacuate the fluid between the moisture-proof and heat-insulating jacket 2 and the camera 1 to ensure that no fluid appears between the two.

[0030] refer to Figure 7 , Figure 7 It is a schematic diagram of the structure of a moisture-proof and heat-insulating jacket for a camera with ear plates of the present invention. In the figure, at least one pair of ear plates are provided on both sides of the moisture-proof and heat-insulating jacket 2, namely a first ear plate 202 and a second ear plate 203, which are respectively fixed on the left and right sides of the moisture-proof and heat-insulating jacket 2. The first ear plate 202 and the second ear plate 203 are used to enable the present invention to be fixedly connected with other equipment. It should be noted that the ear plate 203 is only an optional fixed connection workpiece, and any common fixed connection workpiece that acts on the fixed connection with other equipment can replace this structure and should not be regarded as exceeding the protection scope of the present invention.

[0031] Example 2: Reference Figure 8 , Figure 8 It is a schematic diagram of the structure of the detachable moisture-proof and heat-insulating jacket of the utility model. The difference from Example 1 is that the moisture-proof and heat-insulating jacket 2 in the figure is split into two "n"-shaped structures (i.e., a first moisture-proof and heat-insulating jacket and a second moisture-proof and heat-insulating jacket). The end faces of the two are butted together to wrap the camera 1 and are fixed by a bolt structure or other fastening structure. The advantage of using this structure is that it is easy to install, but gas may remain between the camera 1 and the moisture-proof and heat-insulating jacket 2. This problem can be solved by combining the structures in the above embodiments.

[0032] When the user uses the utility model, the best option is to assemble it in a vacuum assembly area to ensure that when the moisture-proof and heat-insulating jacket 2 is put on, no gas or liquid will remain between the camera 1 and the moisture-proof and heat-insulating jacket 2, and the semiconductor refrigeration chip 3 is energized to form an overall or local temperature control for the camera. Since there is no air or liquid residue between the camera 1 and the moisture-proof and heat-insulating jacket 2, the camera 1 and the internal circuit board of the camera 1 are always in a dry state to avoid corrosion damage.
