Description

Technical Field

[0001] This utility model belongs to the field of industrial camera technology, and in particular relates to a multi-interface industrial camera with a dustproof device. Background Technology

[0002] Industrial cameras serve as critical image acquisition devices in the industrial field, widely used in quality inspection, precision positioning, robot guidance, and other scenarios. Their stability and image quality directly affect system performance. However, in harsh industrial environments with high dust, particulate matter, or high humidity, existing industrial cameras often suffer from insufficient dustproof design. This is especially true for multi-interface integrated cameras, where dust, oil, or condensation easily accumulates in the lens assembly and interface areas, leading to blurred images, reduced light transmittance, and even poor electrical contact or short circuits. Existing technologies often employ overall sealing or the addition of simple protective covers, such as static sealing of the lens module with O-rings or adding dust covers to the interface. While these methods can block some large particulate contaminants, they are insufficient to address the continuous intrusion of fine dust. Dust easily accumulates on the lens surface and between the interface terminals, forming a difficult-to-clean stain layer that affects the stability of the optical path. In addition, existing designs focus on dust prevention of the interface itself, but neglect dust management around the lens. Dust may seep in through the assembly gap between the protective cover and the camera body, and long-term accumulation may cause wear and tear on the lens module or corrosion of the coating. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-interface industrial camera with a dustproof device, which aims to solve the technical problems of insufficient dustproof capability and mutual restriction between dustproof and optical functions in existing industrial cameras.

[0004] To achieve the above objectives, this utility model provides a multi-interface industrial camera with a dustproof device, including a camera body. One end of the camera body has a camera lens, and a protective cover is fixedly connected to the camera lens. Below the protective cover is a dustproof end body detachably connected to the camera body. The dustproof end body includes a base, and an annular component extends above the base. The annular component has an upward-opening annular groove around its periphery, the diameter of which is larger than the diameter of the protective cover, forming a dust collection channel between the annular groove and the protective cover. Above the protective cover is a light control board detachably connected to the camera body. The center of the light control board has an integrally connected viewing lens, which is aligned vertically with the protective cover and the camera lens. The other end of the camera body also has several electrical interfaces connected to it.

[0005] Furthermore, a first sleeve portion is provided between the annular component and the protective cover, and the dustproof end body is sleeved around the first sleeve portion.

[0006] Furthermore, a second sleeve portion is provided between the annular component and the base, and the outermost edge of the annular component is directly larger than the diameter of the second sleeve portion, so that the second sleeve portion, the base, and the annular component enclose and form a lateral dust collection groove.

[0007] Furthermore, the lower end of the protective cover is tightly fitted to the upper end of the annular component.

[0008] Furthermore, the camera body has two symmetrical outer sidewalls with arc slides, and the light control board has arc sliders at both ends. The arc sliders slide on the corresponding arc slides to form an electrical connection.

[0009] Furthermore, the lighting control board is equipped with four sets of lighting modules, which are arranged in a square structure and surround the perspective mirror.

[0010] Furthermore, the interface includes a first interface, a second interface, and a third interface, all of which are located on the back of the camera body. The first interface is a network port for connecting with an RJ45 plug adapter; the second interface is a square connector interface for connecting with a round connector adapter; and the third interface is a Type-C interface for connecting with a Type-C plug adapter.

[0011] Furthermore, the interface also includes a fourth interface, a fifth interface, and a sixth interface, all of which are located on the side of the camera body. The fourth interface is an optical fiber interface for communication connection with a remote control terminal; the fifth interface is an HDMI interface for transmitting high-definition images from the camera; and the sixth interface is an I / O interface for receiving external trigger signals, or for sending flash synchronization signals or event completion signals.

[0012] Furthermore, the base is provided with a screw hole, and a threaded hole is provided at one end of the camera body near the base, through which a screw passes and is threadedly connected to the threaded control.

[0013] The above-mentioned technical solutions of the multi-interface industrial camera with dustproof device provided in this embodiment of the utility model have at least one of the following technical effects: By designing an integrated structure with a dustproof end body and a dust collection channel, an annular groove is constructed around the camera lens, allowing dust to fall into the channel instead of adhering to the optical surface. At the same time, the detachable dustproof end body works in conjunction with the lighting control board to ensure lossless transmission of supplementary light through the lens and to achieve modular dustproof maintenance of the interface area. This effectively solves the niche but critical technical problems of insufficient dustproof capability and mutual constraints between dustproof and optical functions in existing industrial cameras with a compact layout of multiple interfaces.

The following description is based on the accompanying drawings. Figure 1 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0021] In one embodiment of this utility model, such as Figure 1-2As shown, a multi-interface industrial camera with a dustproof device is provided, including a camera body 100. A camera lens 110 is provided at one end of the camera body 100, and a protective cover 120 is fixedly connected to the camera lens 110. A dustproof end body 130, detachably connected to the camera body 100, is provided below the protective cover 120. The dustproof end body 130 includes a base 140, and a circular ring 150 extends above the base 140. An upward-opening annular groove 160 is provided around the periphery of the circular ring 150. The diameter of the annular groove 160 is larger than the diameter of the protective cover 120, so that the annular groove 160 and the protective cover 120 enclose to form a dust collection channel 170. A first sleeve portion 151 is provided between the circular ring 150 and the protective cover 120, and the dustproof end body 130 is fitted around the first sleeve portion 151. A second sleeve portion 152 is provided between the annular component 150 and the base 140. The outermost edge of the annular component 150 is directly larger than the diameter of the second sleeve portion 152, so that the second sleeve portion 152, the base 140, and the annular component 150 enclose and form a lateral dust collection groove 180. Figure 4 (As shown). The lower end of the protective cover 120 fits tightly against the upper end of the ring 150. Above the protective cover 120, there is also a light control plate 200 that is detachably connected to the camera body 100. The middle of the light control plate 200 is provided with an integrally connected lens 210. The lens 210 is aligned vertically with the protective cover 120 and the camera lens 110. The other end of the camera body 100 is also provided with several electrical interfaces 300 connected to it.

[0022] Specifically, such as Figure 3-4As shown, when an industrial camera operates in a dusty environment, dust particles tend to accumulate around the camera lens 110 assembly under the influence of gravity or airflow. At this point, the tight fit between the lower end of the protective cover 120 and the upper end of the annular component 150 forms the first line of defense, effectively preventing dust from falling directly vertically into the core area where the protective cover 120 meets the camera lens 110. Dust particles that fail to be blocked by this seal and fall along the periphery of the assembly first encounter an "eaves" structure formed by the outermost edge of the annular component 150, with a diameter larger than the second sleeve portion 152. This structural difference, together with the second sleeve portion 152 and the base 140, forms the crucial lateral dust collection groove 180. This groove, as a primary dust collection area, efficiently captures and accommodates larger dust particles or splashed liquids coming from the side, preventing them from further penetrating inwards, thus completing the initial purification and interception. Fine dust particles, or those that bypass the primary interception, enter the dust collection channel 170 formed by the annular bottom groove 160 and the protective cover 120 as they move downwards. This upward-opening annular structure acts as a primary collector, utilizing the dust's own gravity to stably contain it within the groove, preventing dust accumulation near the critical optical path directly above the lens. Ultimately, this three-dimensional dustproof network, consisting of the lateral dust collection grooves 180 (radial protection) and the top dust collection channel 170 (axial protection), continuously guides and fixes dust from the optical core area to designated "trap" areas, greatly enhancing the camera's reliability in extreme dust environments. This effectively solves the niche but crucial technical challenges of insufficient dustproof capabilities and the mutual constraints between dustproof and optical functions in existing industrial cameras with compact multi-interface layouts.

[0023] Furthermore, such as Figure 1-2As shown, the camera body 100 has two symmetrical outer sidewalls with arc slides 400, and the light control plate 200 has arc sliders 410 at its upper and lower ends. The arc sliders 410 slide on the corresponding arc slides 400 to form an electrical connection. The light control plate 200 has four sets of light modules 220, which are arranged in a square structure and surround the lens 210. Specifically, when it is necessary to install or replace the light control plate 200, the operator only needs to align the arc sliders 410 at the upper and lower ends of the light control plate 200 with the corresponding arc slides 400 on the outer sidewall of the camera body 100, and then push it in smoothly along the slide direction. This sliding process simultaneously completes two key actions: First, mechanical positioning and fixing. The precise cooperation between the slider and the track ensures that the lighting control board 200 can move accurately and stably to the preset working position, so that the lens 210, the protective cover 120 below, and the camera lens 110 are strictly kept on the same vertical optical axis to avoid misalignment. Second, automatic establishment of electrical connection. During the process of the slider sliding into the end point of the track, its internal electrical contacts reliably contact the conductive track, instantly forming a stable electrical connection path, powering the lighting control board 200 and realizing communication with the camera body 100. The two pairs of arc tracks 400 and the arc slider 410 form a positive and negative conductive circuit, eliminating the need for additional cable plugging or cumbersome wiring operations. Furthermore, the light control board 200 does not function independently of the dustproof end body 130. The light control board 200's sliding connection method easily induces a localized electrostatic field, which acts as a powerful "dust collector," actively attracting insulating dust particles dispersed in the air. Once this dust accumulates on the electrical contact surface, it increases contact resistance, causes signal instability, and can even lead to short circuits, seriously endangering the camera's electrical safety. Therefore, the dustproof end body 130 and the protective cover 120 need to work together to block dust. In this way, even if a small amount of dust is attracted to the contact point between the arc slider 410 and the arc track 400 due to electrostatic attraction, this dust will be effectively blocked by the physical barrier of the dustproof end body 130 when it attempts to spread under vibration or airflow disturbance.

[0024] Furthermore, such as Figure 2 , 5As shown, interface 300 includes a first interface 310, a second interface 320, and a third interface 330, all located on the back of the camera body 100. The first interface 310 is an Ethernet port for connecting to an RJ45 connector; the second interface 320 is a square connector interface for connecting to a round connector; and the third interface 330 is a Type-C interface for connecting to a Type-C connector. Interface 300 also includes a fourth interface 340, a fifth interface 350, and a sixth interface 360, all located on the side of the camera body 100. The fourth interface 340 is an optical fiber interface for communication with a remote control terminal; the fifth interface 350 is an HDMI interface for transmitting high-definition images from the camera; and the sixth interface 360 ​​is an I / O interface for receiving external trigger signals or sending flash synchronization signals or event completion signals.

[0025] Furthermore, such as Figure 2 As shown, the base 140 is provided with a screw hole 500, and the camera body 100 is provided with a threaded hole 510 near the base 140. A screw passes through the screw hole 500 and is threadedly connected to the screw control.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
