[0053] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0054] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0055] The complex environmental factors in industrial settings can easily adversely affect the optical performance of industrial cameras. For example, in welding industrial settings, welding slag splashes everywhere. If the slag splashes onto the filter of an industrial camera, it will damage the filter, ultimately resulting in impaired optical performance, reduced accuracy, and decreased reliability.

[0056] In view of this, the present invention provides an industrial camera, such as... Figure 1 , Figure 2a and Figure 2b As shown, the industrial camera includes a housing 100 and at least one optical module. The housing 100 has at least one optical opening 110, which corresponds one-to-one with at least one optical module. The optical elements of the optical module are opposite to the corresponding optical opening 110. The industrial camera also includes at least one protective component 300. The protective component 300 is disposed at at least one optical opening 110. The protective component 300 includes a light-transmitting protective plate 310 and a mounting frame 320. The mounting frame 320 is disposed around the corresponding optical opening 110 to detachably connect the light-transmitting protective plate 310 to the housing 100.

[0057] After a light-transmitting protective plate 310 is installed at the optical opening 110, foreign objects (e.g., welding slag) in the industrial camera's operating environment are blocked outside the housing 100 by the light-transmitting protective plate 310, protecting the optical elements at the optical opening 110. This prevents damage to the optical elements from foreign objects in the operating environment, thereby extending the service life of the industrial camera. Furthermore, if the light-transmitting protective plate 310 is damaged, a new light-transmitting protective plate 310 can be replaced, thereby reducing the maintenance cost of the industrial camera.

[0058] In this embodiment of the invention, the specific material of the light-transmitting protective plate 310 is not specifically limited, as long as it does not affect the light path at the optical opening 110. As an optional implementation, the light-transmitting protective plate 310 can be made of high-transmittance glass.

[0059] In this embodiment of the invention, there are no special limitations on the type or specific number of optical modules in the industrial camera. For example, the industrial camera may include two optical modules. In this embodiment, the protective component 300 may be provided only at the optical opening 110 of one of the optical modules, or the protective component 300 may be provided at the optical opening 110 of both optical modules.

[0060] exist Figure 1 In the embodiment shown, the industrial camera is a line laser camera, and the two optical modules of the line laser camera are a stereo camera and a laser emission module, respectively. Of course, this utility model is not limited to this, and the industrial camera can also be any one of the following: a time-of-flight (ToF) camera, a color depth (RGB-D, Red Green Blue-Depth) camera, or a 2D (two-dimensional) camera.

[0061] In this embodiment of the invention, there are no special limitations on how the mounting frame 320 detachably connects the light-transmitting protective plate 310 to the housing 100. For example, the light-transmitting protective plate 310 can be mounted on the mounting frame 320 using fasteners such as bolts. In this embodiment, both the light-transmitting protective plate 310 and the corresponding mounting frame need to be provided with threaded holes. When replacing the light-transmitting protective plate 310, the bolts need to be removed first, and then the light-transmitting protective plate 310 needs to be removed.

[0062] To ensure the integrity of the light-transmitting protective panel 310 during installation, optionally, such as Figure 2a , Figure 2b , Figure 3 , Figure 6a ,as well as Figure 6bAs shown, the mounting frame 320 includes a base frame 321, a top frame 322, and an elastic clamping assembly 323. The base frame 321 is disposed on the housing 100 and surrounds the corresponding optical opening 110. The top frame 322 is stacked on the side of the base frame 321 opposite to the housing 100 and is fixedly connected to the base frame 321. A receiving gap is formed between the top frame 322 and the base frame 321. The elastic clamping assembly 323 is disposed between the top frame 322 and the base frame 321 (i.e., in the receiving gap). A light-transmitting protective plate 310 is inserted between the elastic clamping assembly 323 and one of the top frame 322 and the base frame 321, and the light-transmitting protective plate 310 is pressed against one of the top frame 322 and the base frame 321 by the elastic deformation of the elastic clamping assembly 323.

[0063] By using the elastic clamping assembly to hold the light-transmitting protective plate 310 against the top frame 322 or the base frame 321, it is possible to avoid drilling holes in the light-transmitting protective plate 310 and to prevent the light-transmitting protective plate 310 from breaking due to drilling, thus ensuring the integrity of the light-transmitting protective plate 310 during installation.

[0064] In this embodiment of the invention, the shapes of the base frame 321 and the top frame 322 are not specifically limited. Specifically, the shapes of the base frame 321 and the top frame 322 can be determined according to the shape of the corresponding optical opening 110.

[0065] For example, in Figure 1 and Figure 5 In the embodiment shown, the upper left optical opening 110 is a square opening, and the corresponding base frame 321 and top frame 322 are also square frames; the lower right optical opening 110 is a rectangular opening, and the corresponding base frame 321 and top frame 322 are also rectangular frames.

[0066] To ensure that the light-transmitting protective plate 310 is reliably installed in the mounting frame 320 and to facilitate the installation of the light-transmitting protective plate 310, the top frame 322 may optionally include a top frame body 322d and at least one limiting stop boss 322c.

[0067] It is easy to understand that the top frame body 322d and the corresponding base frame 321 are arranged opposite to each other and fixedly connected to surround the corresponding optical opening 110, and the receiving interval is formed between the interconnected top frame body 322d and base frame 321.

[0068] The light-transmitting protective plate 310 is pluggably disposed in the receiving interval through the insertion port of the receiving interval.

[0069] The limiting stop boss 322c is disposed on the periphery of the receiving interval so that the light-transmitting protective plate 310 is located inside the limiting stop boss 322c.

[0070] In the embodiments of this utility model, such as Figures 6a to 6c As shown, the limiting stop boss 322c is a strip-shaped component provided on the top frame body 322d. After the top frame 322 and the base frame 321 are assembled, the limiting stop boss 322c is located at the insertion end of the receiving interval and locks the light-transmitting protective plate 310, preventing the light-transmitting protective plate 310 from coming out of the insertion end of the receiving interval.

[0071] like Figure 6c As shown, the limiting stop boss 322c is a protrusion provided at the edge of the top frame body 322d.

[0072] In this embodiment of the utility model, the setting position of the limiting stop boss 322c is not specially limited, as long as it can limit the light-transmitting protective plate 310.

[0073] In this embodiment of the utility model, the specific structure of the top frame body 322d is not specifically limited.

[0074] exist Figure 6a In the embodiment shown, the top frame body 322d is a square frame.

[0075] exist Figure 6b In the illustrated embodiment, the top frame body 322d includes a flat frame portion 322d1 and a side wall portion 322d2 disposed on the side of the flat frame portion 322d1 facing the base frame 321. The elastic clamping assembly is located inside the side wall portion 322d2.

[0076] In this embodiment of the invention, the specific structure of the base frame 321 is not specifically limited. For example, in Figure 3 In the embodiment shown, the base frame 321 includes a base frame body 321a and an auxiliary boss 321b formed on the base frame body 321a.

[0077] The base frame body 321a is arranged around the corresponding optical opening 110 and is fixedly connected to the top frame 322. The auxiliary boss 321b is arranged on the surface of the base frame body 321a facing the top frame 322.

[0078] The light-transmitting protective plate 310 is located inside the auxiliary boss 321b. By setting the auxiliary boss 321b, the light-transmitting protective plate 310 can be further limited.

[0079] To facilitate the installation and replacement of the light-transmitting protective plate 310, optionally, an installation notch is formed on the outer surface of the mounting frame 320, which is located at the insertion port, and a portion of the light-transmitting protective plate 310 is located in the installation notch.

[0080] When replacing the light-transmitting protective plate 310, the light-transmitting protective plate 310 can be pulled directly from the installation notch and pulled out of the receiving gap.

[0081] like Figure 6a and Figure 6b As shown, a portion of the mounting notch is formed on the top frame 322, and another portion of the mounting notch is formed on the base frame 321.

[0082] As an optional implementation, limit stop bosses 322c are provided on both sides of the mounting notch.

[0083] exist Figure 3 In the embodiment shown, two auxiliary bosses 321b are respectively disposed on both sides of the mounting notch.

[0084] When pulling out the light-transmitting protective plate 310, it is necessary to press the light-transmitting protective plate 310 towards the base frame 321 to release the limiting stop boss 322c from limiting the light-transmitting protective plate 310.

[0085] In this embodiment of the utility model, the specific structure of the elastic clamping component 323 is not particularly limited. It is sufficient that it is fixed on one of the base frame body and the top frame and can hold the light-transmitting protective plate 310 against the other of the base frame body and the top frame through the restoring force of elastic deformation.

[0086] exist Figure 3 In the embodiment shown, the elastic clamping assembly 323 includes at least one mounting member 323c and at least one elastic strip 323d. The mounting member 323c is fixed to one of the base frame 321 and the top frame 322. At least one elastic strip 323d is provided on the mounting member 323c. One end of the elastic strip 323d is fixed to the corresponding mounting member 323c. The elastic strip 323d abuts against the light-transmitting protective plate and undergoes elastic deformation.

[0087] It should be noted that in the above embodiment, one end of the elastic strip 323d is fixed, and the other end is a free end.

[0088] The length direction of the elastic strip 323d is consistent with the length direction of the side on the mounting frame 320 where the elastic strip 323d is located, thus preventing obstruction of the optical opening 110. In this embodiment of the invention, there is no special limitation on the number of mounting members 323c and elastic strips 323d, as long as the light-transmitting protective plate 310 can be reliably abutted against the mounting frame. Figure 3 In the embodiment shown, two mounting members 323c are provided on both sides of the receiving interval, and each mounting member is provided with an elastic strip 323d.

[0089] In one optional implementation, the elastic clamping assembly 323 can be disposed on the base frame 321. Specifically, the elastic strip 323d and the mounting member 323c are disposed on the portions of the base frame body located on both sides of the insertion port. To facilitate the insertion of the light-transmitting protective plate 310, optionally, as... Figure 4 As shown, the elastic strip 323d includes a mounting portion 323d1 and an abutment portion 323d2 arranged sequentially along the length direction of the elastic strip 323d. The mounting portion 323d1 is closer to the insertion port than the abutment portion 323d2 of the elastic strip 323d to which the mounting portion 323d1 belongs.

[0090] Optionally, the abutment 323d2 can be bent into an arc shape, thereby facilitating the insertion of the light-transmitting protective plate 310 between the abutment 323d2 and the top frame 322.

[0091] In this embodiment of the utility model, there are no special limitations on how the elastic strip is installed on the mounting member 323c. For example, the elastic strip 323d can be installed on the mounting member 323c using fasteners such as bolts and screws. Since only one end of the elastic strip 323d is fixed to the mounting member 323c, in order to prevent the elastic strip 323d from deflecting during use or during the insertion and removal of the light-transmitting protective plate 310, the mounting member 323c may optionally include a boss body 323c1 and a limiting member 323c2. The boss body 323c1 is disposed on the base frame 321, and the limiting member 323c2 is formed on the mounting surface of the boss body 323c1. The elastic strip 323d is installed on the mounting surface of the corresponding boss body 323c1 by the fasteners, and the limiting member 323c2 is located at one end of the mounting portion 323d1 of the corresponding elastic strip 323d.

[0092] Of course, this utility model is not limited to this; the elastic strip 323d can also be fixed to the mounting part 323c by welding.

[0093] exist Figure 5 In the embodiment shown, the resilient clamping assembly 323 includes at least one sub-clamping assembly. Figure 7 As shown, the sub-clamping assembly includes a pressure bar 323a and at least one elastic abutment 323b, the elastic abutment 323b including an elastic element 323b1 and a spherical element 323b2.

[0094] At least one limiting through hole 323a1 is formed on the pressure strip 323a, and at least one limiting through hole 323a1 corresponds to at least one elastic abutment 323b.

[0095] There is a gap between the portion of the pressure strip 323a that forms a limiting through hole 323a1 and the base frame 321, and a corresponding elastic element 323b1 is provided in this gap. As shown in the figure, one end of the elastic element 323b1 is connected to the base frame 321, and a corresponding spherical element 323b2 is rotatably provided at the other end of the elastic element 323b1. The spherical element 323b2 is provided in the corresponding limiting through hole 323a1, and a portion of the spherical element 323b2 protrudes from the opening of the limiting through hole 323a1 facing the light-transmitting protective plate 310 and abuts against the light-transmitting protective plate 310.

[0096] When the light-transmitting protective plate 310 is inserted and pulled out, the spherical member 323b2 rotates, reducing the friction force on the light-transmitting protective plate 310, ensuring the smooth progress of the insertion and extraction process, and preventing the light-transmitting protective plate 310 from being damaged during the insertion and extraction process.

[0097] In addition, the spherical part 323b2 has a smooth surface, which will not generate excessive stress concentration when the light-transmitting protective plate 310 is pressed against the top frame 322, thereby extending the service life of the light-transmitting protective plate 310.

[0098] In this embodiment of the utility model, the limiting through hole 323a1 can limit the spherical part 323b2 to prevent the spherical part 323b2 from being lost after separating from the elastic part 323b1 after the light-transmitting protective plate 310 is pulled out.

[0099] In this embodiment of the utility model, the specific type of the elastic element 323b1 is not specifically limited, as long as it is elastic. Optionally, the elastic element 323b1 can be a spring. The diameter of the opening of the limiting through hole 323a1 facing the top frame 322 is smaller than the outer diameter of the elastic element 323b1. In this way, under the limiting action of the limiting through hole 323a1, the elastic element 323b1 and the spherical element 323b2 can only be pushed up or contracted along the axial direction of the limiting through hole 323a1, and will not come out of the limiting through hole 323a1, effectively avoiding local movement of the elastic element 323b1 and the spherical element 323b2.

[0100] To better limit the spherical part 323b2, optionally, the thickness of the portion of the pressure strip 323a with the limiting through hole 323a1 is greater than the radius of the spherical part 323b2.

[0101] To better accommodate the spherical member 323b2, optionally, the diameter of the limiting through hole 323a1 gradually decreases along the direction from the base frame 321 to the top frame 322. That is, the limiting through hole 323a1 is approximately trumpet-shaped. Setting the limiting through hole 323a1 to a trumpet shape can effectively increase the formation of the spherical member 323b2 during the lifting process and avoid the situation where the spherical member 323b2 cannot be ejected from the pressure strip 323a.

[0102] In the embodiment shown in the figure, the sub-clamping components can be disposed on both sides of the insertion port of the receiving cavity.

[0103] To facilitate the assembly of the base frame 321 and the top frame 322 together, such as Figure 6a As shown, a first positioning structure is formed on the base frame, and a second positioning structure is formed on the top frame, wherein the first positioning structure matches the second positioning structure.

[0104] In this embodiment of the utility model, there is no special limitation on the specific types of the first positioning structure and the second positioning structure, as long as the two match and the positioning of the base frame 321 and the top frame 322 is achieved.

[0105] exist Figure 6a In the embodiment shown, a first positioning structure is formed on one side of the base frame 321. The first positioning structure includes two first positioning protrusions 321a1 and a first positioning groove 321a2 formed between the two first positioning protrusions 321a1. A second positioning structure is formed on the corresponding side of the top frame 322. The second positioning structure includes two second positioning grooves 322b and a second positioning protrusion 322a formed between the two second positioning grooves 322b.

[0106] The shape and position of the first positioning protrusion 321a1 match the shape and position of the second positioning groove 322b, and the shape and position of the first positioning groove 321a2 match the shape and position of the second positioning protrusion 322a. By aligning the first positioning protrusion 321a1 with the second positioning groove 322b and aligning the first positioning groove 321a2 with the second positioning protrusion 322a, the alignment of the base frame 321 and the top frame 322 can be achieved quickly.

[0107] In addition to its positioning function, the first positioning structure and the second positioning structure can limit the light-transmitting protective plate 310 and further prevent the light-transmitting cover plate 310 from falling off between the base frame and the top frame.

[0108] As described above, the optical modules include a stereo camera and a laser emitting module.
