Description

Technical Field

[0001] This utility model relates to the technical field of machine vision, and in particular to a camera protective cover and an industrial camera. Background Technology

[0002] Currently, industrial cameras are widely used in agriculture, healthcare, automotive manufacturing, industrial automation, drones, traffic monitoring, security monitoring, machine vision systems, quality control, and logistics warehousing. In certain harsh application scenarios, the camera window of an industrial camera may be damaged. For example, in welding operations, industrial cameras are typically mounted on welding torches. The camera scans the target part to be welded before welding to position the torch. However, during welding, because the industrial camera is close to the welding position, spatter generated during welding may damage the camera window. Therefore, a camera shield is needed to ensure stable and reliable operation of the industrial camera.

[0003] In related technologies, camera protective covers are typically pneumatically driven. A pneumatic protective cover generally includes a drive cylinder, a protective baffle, and a transmission assembly. The drive cylinder, through the transmission assembly, drives the protective baffle to slide up and down or swing left and right, allowing the baffle to slide to the front of the industrial camera's viewfinder to cover it.

[0004] However, due to the large size of the air passage interface of the drive cylinder in the pneumatic protective cover, and the need for an additional air supply system to power the drive cylinder, the pneumatic protective cover is quite bulky. The drive cylinder typically needs to be mounted on the side wall of the industrial camera via a mounting plate. Furthermore, since the drive cylinder is mounted on the side wall of the industrial camera to drive the front drive baffle, the transmission assembly needs to include structures such as finger blocks and adapter blocks, making the transmission assembly quite complex. Simultaneously, because it requires an air system to power the drive cylinder, the pneumatic protective cover also suffers from drawbacks such as poor motion speed stability, slow signal transmission over long distances, high noise levels, high maintenance costs, and cumbersome control.

[0048] Beneficial effects:

[0049] This utility model provides a camera protective cover and an industrial camera, with a drive arm mounted on the first outer side of the protective cover housing. The first end of the drive arm is fixedly connected to a transmission mechanism disposed inside the protective cover housing, and the second end of the drive arm is fixedly connected to a protective flip cover.

[0050] Compared to pneumatic drives in related technologies, the drive motor eliminates the need for an additional air supply system, large air inlets, and drive cylinders. The rotation of the protective cover is achieved simply by the drive motor rotating a drive arm located on the first outer side of the protective cover. This simplifies the structure and effectively reduces the size of the drive components, further minimizing the overall size of the camera cover. Furthermore, because the camera cover uses a drive motor for power, compared to cylinder-driven systems, it can quickly rotate the drive arm on the first outer side of the protective cover, allowing for rapid opening and closing of the protective cover.

[0051] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0078] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art based on this application are within the protection scope of the present utility model.

[0079] This utility model provides a camera protective cover, such as Figures 1 to 3 As shown, Figure 1 This is a first-view structural schematic diagram of the camera protective cover provided by this utility model. Figure 2 This is a structural schematic diagram of the camera protective cover provided by this utility model from a second perspective. Figure 3 for Figure 1 The diagram shows the structure of the camera protective cover without the upper shell installed. The camera protective cover includes: a protective flip cover 1, a drive module 2, a transmission mechanism 3, and a drive arm 4; the drive module 2 includes: a drive motor 21 and a protective cover housing 22; the drive motor 21 is located inside the protective cover housing 22; the drive arm 4 is installed on the first outer side 2201 of the protective cover housing 22; the first end 401 of the drive arm is connected to the drive motor 21 via the transmission mechanism 3; the second end 402 of the drive arm is fixedly connected to the protective flip cover 1.

[0080] like Figures 4 to 6a As shown, Figure 4 This utility model provides a schematic diagram of the structure of an industrial camera with a protective flip cover that obscures the camera window. Figure 5 This is a schematic diagram of the structure of an industrial camera provided by this utility model when the protective flip cover does not cover the camera window. Figure 6a for Figure 1 The diagram shows a cross-sectional view of the camera protective cover along the AA direction, with the protective flip cover not covering the camera window. The drive arm 4 is used to rotate the protective flip cover 1 around the motor shaft 211 of the drive motor 21 under the drive of the drive motor 21, so that the protective flip cover 1 flips up and down to cover or not cover the camera window 110 of the camera body 100.

[0081] In this embodiment, the drive arm 4 is mounted on the first outer side 2201 of the protective cover housing 22. The first end 401 of the drive arm is fixedly connected to the transmission mechanism 3 disposed inside the protective cover housing 22, and the second end 402 of the drive arm is fixedly connected to the protective flip cover 1. This allows the transmission mechanism 3 to drive the drive arm 4 disposed on the first outer side 2201 of the protective cover housing 22 to rotate under the drive of the drive motor 21, thereby enabling the drive arm 4 to drive the protective flip cover 1 to rotate around the motor shaft 211.

[0082] Compared to pneumatic drives in related technologies, the drive motor 21 does not require an additional air supply system, nor does it need a large air inlet or drive cylinder. The rotation of the protective flip cover 1 is achieved simply by the drive motor 21 driving the drive arm 4 located on the first outer surface 2201 of the protective cover housing 22. This simplifies the structure and effectively reduces the size of the drive components, further minimizing the overall size of the camera protective cover. Furthermore, since the camera protective cover uses the drive motor 21 as its power source, compared to drive cylinders, the drive motor 21 can quickly rotate the drive arm 4 located on the first outer surface 2201 of the protective cover housing 22, allowing the protective flip cover 1 to open and close rapidly.

[0083] The camera protective cover provided in this embodiment can shorten the exposure time of the industrial viewing window 110 on the camera body 100 in hazardous environments, further extending the maintenance cycle and service life of the camera body 100. Furthermore, the drive motor 21 emits relatively little noise during operation.

[0084] Specifically, the protective flip cover 1 has two working positions: covered and uncovered. For example... Figure 4 As shown, when the industrial camera needs protection, the protective flip cover 1, driven by the drive motor 21, can rotate and lower to the front of the camera window 110, covering the camera window 110. Figure 5 As shown, when the industrial camera needs to operate normally, the protective flip cover 1, driven by the drive motor 21, can flip upwards at a certain angle from the front of the camera window 110, thereby avoiding obstruction of the camera window 110. Figure 5 As shown, the protective flip cover 1 can be flipped 90 degrees, or more than 90 degrees, as long as it is positioned to avoid the camera window 110.

[0085] like Figure 4 and Figure 5 As shown, the drive arm 4 is set on the outside of the protective cover shell 22. When the drive arm 4 is repaired or replaced, there is no need to remove the protective cover shell 22. The drive arm 4 can be directly disassembled and assembled, which can effectively improve the efficiency of replacing and repairing the drive arm 4.

[0086] like Figure 2 and Figure 6b As shown, Figure 6b for Figure 1 The diagram shows a cross-sectional view of the camera protective cover along the BB direction, with the protective flip cover obscuring the camera window. A shock-absorbing pad 11 can also be provided on the side of the protective flip cover 1 that contacts the camera window 110. When the protective flip cover 1 covers the camera window 110, the shock-absorbing pad 11 between them can form a buffer, thereby protecting the camera window 110.

[0087] In some embodiments of this utility model, such as Figures 1 to 6b As shown. The camera protective cover also includes: a connecting arm 5 and a connecting mechanism 6; the connecting arm 5 is mounted on the protective cover housing 22 and has a second outer side 2202 opposite to the first outer side 2201; the first end 501 of the connecting arm is rotatably connected to the second outer side 2202 of the protective cover housing 22 via the connecting mechanism 6; the second end 502 of the connecting arm is fixedly connected to the protective flip cover 1; the second end 502 of the connecting arm and the second end 402 of the driving arm are located on the same surface of the protective flip cover 1 and are symmetrically spaced apart, so that the first end 501 of the connecting arm can rotate relative to the second outer side 2202 as the protective flip cover 1 rotates.

[0088] In this embodiment, a connecting arm 5 is provided on the protective cover shell 22 on the second outer side 2202 opposite to the first outer side 2201 on which the driving arm 4 is installed. The first end 501 of the connecting arm is rotatably connected to the protective cover shell 22 via a connecting mechanism 6, and the second end 502 of the connecting arm is fixedly connected to the protective flip cover 1. Figure 4 and Figure 5 As shown, when the protective cover 1 rotates under the drive of the drive arm 4, the protective cover 1 can drive the connecting arm 5 to rotate synchronously. The connecting arm 5 and the connecting mechanism 6 can provide support to the side of the protective cover 1 away from the drive arm 4 during the rotation of the protective cover 1, thereby ensuring the stability of the protective cover 1.

[0089] In some embodiments of this utility model, such as Figures 6a to 9 As shown, Figure 7a for Figure 1 The image shown is an exploded view from a first-person perspective of the camera housing. Figure 7b for Figure 7a The enlarged view shown in M3 is a partial view. Figure 8a for Figure 1 The image shows an exploded view from a second-person perspective of the camera housing. Figure 8b for Figure 8a The enlarged view shown in M4 is a partial view. Figure 9 for Figure 1The image shows a third-person exploded view of the camera housing. A first mounting through hole 221 is provided on the first outer side 2201 of the protective cover shell 22; a second mounting through hole 222 is provided on the second outer side 2202 of the protective cover shell 22; the transmission mechanism 3 includes: a drive shaft 31; a first end 3101 of the drive shaft is fixedly connected to the motor shaft 211 of the drive motor 21; a second end 3102 of the drive shaft extends out from the first mounting through hole 221 of the protective cover shell 22 and is fixedly connected to the first end 401 of the drive arm; the drive shaft 31 rotates under the drive of the motor shaft 211 of the drive motor 21 to drive the rotation of the drive arm 4; the connecting mechanism 6 includes: a connecting shaft 61; a first end 6101 of the connecting shaft is located inside the protective cover shell 22 and spaced apart from the drive motor 21; a second end 6102 of the connecting shaft extends out from the second mounting through hole 222 of the protective cover shell 22 and is fixedly connected to the first end 501 of the connecting arm; the connecting shaft 61 rotates under the drive of the connecting arm 5.

[0090] In this embodiment, the components inside the camera housing can be coaxially arranged along the mounting centerline a. The drive shaft 31 of the transmission mechanism 3 is fixedly connected to the motor shaft 211 through the shaft hole 311 of the first end 3101 of the drive shaft. The second end 3102 of the drive shaft passes through the first mounting through hole 221 on the first outer side 2201 and is fixedly connected to the first end 401 of the drive arm. This allows the drive shaft 31 to rotate under the drive of the drive motor 21, thereby rotating the drive arm 4 and causing the protective flip cover 1 to rotate around the motor shaft 211. This allows the protective flip cover to switch between covering or not covering the camera window 110. Compared to pneumatic protective covers in related technologies, the transmission mechanism 3 in this embodiment can control the protective flip cover 1 solely through the drive shaft 31, eliminating the need for complex structures such as finger blocks and adapter blocks. This further reduces the overall size of the camera housing.

[0091] Meanwhile, the second end 6102 of the connecting shaft passes through the second mounting through hole 222 and is fixedly connected to the first end 501 of the connecting arm. The first end 6101 of the connecting shaft is located inside the protective cover housing 22 and is spaced apart from the drive motor 21. This allows the connecting arm 5 to be fixed to the protective cover housing 22 via the connecting shaft 61. When the protective flip cover 1 rotates, the connecting arm 5 and the connecting shaft 61 provide support for the side of the protective flip cover 1 away from the drive arm 4, thereby ensuring the stability of the protective flip cover 1 during rotation.

[0097] For details, see Figures 6a to 9 The first pivot seat 32 includes: a first housing connecting portion 321 and a first pivot connecting portion 322 perpendicular to the first housing connecting portion 321; the first housing connecting portion 321 is fixed to the first outer side surface 2201 of the protective cover housing 22; the first pivot connecting portion 322 extends into the interior of the protective cover housing 22 through a first mounting through hole 221; the first pivot seat 32 is provided with a first pivot connecting through hole 323 along the length of the pivot shaft, penetrating the first housing connecting portion 321 and the first pivot connecting portion 322; the drive pivot 31 is rotatably inserted into the first pivot seat 32 through the first pivot connecting through hole 323 and is fixedly connected to the first end 401 of the drive pivot arm; The second pivot seat 62 includes: a second housing connecting portion 621 and a second pivot connecting portion 622 perpendicular to the second housing connecting portion 621; the second housing connecting portion 621 is fixed to the second outer side surface 2202 of the protective cover housing 22; the second pivot connecting portion 622 extends into the interior of the protective cover housing 22 through the second mounting through hole 222; the second pivot seat 62 is provided with a second pivot connecting through hole 623 along the length of the pivot shaft, which passes through the second housing connecting portion 621 and the second pivot connecting portion 622; the connecting pivot 61 is rotatably inserted into the second pivot seat 62 through the second pivot connecting through hole 623 and is fixedly connected to the first end 501 of the connecting pivot arm.

[0098] In this embodiment, the first housing connecting portion 321 of the first rotating shaft seat 32 engages with the first mounting groove 225 located on the first outer side surface 2201 of the protective cover housing 22, and the first housing connecting portion 321 can be fixed in the first mounting groove 225 by screws. The first rotating shaft connecting portion 322 of the first rotating shaft seat 32 extends into the interior of the protective cover housing 22 through the first mounting through hole 221. This allows the drive shaft 31 to pass through the first rotating shaft connecting through hole 323 that passes through the first housing connecting portion 321 and the first rotating shaft connecting portion 322. The second housing connecting portion 621 of the second rotating shaft seat 62 engages with the second mounting groove 226 on the second outer side surface 2202 of the protective cover housing 22. The connection relationship between the second rotating shaft seat 62 and the connecting shaft 61 is the same as the connection relationship between the first rotating shaft seat 32 and the drive shaft 31, and will not be described in detail here.

[0099] In some embodiments of this utility model, such as Figures 7a to 9 As shown. On the first housing connecting part 321 of the first pivot seat 32, a first limiting groove 3211 is provided on the side facing the drive arm 4; the first limiting groove 3211 extends along the circumferential direction of the first pivot seat 32 and is exposed on the outside of the protective cover housing 22; on the first end 401 of the drive arm, a first limiting post 43 is provided on the side facing the first pivot seat 32; the first limiting post 43 is embedded in the first limiting groove 3211 and can slide along the extending direction of the first limiting groove 3211 to limit the rotation amplitude of the drive arm 4; On the second housing connecting part 621 of the second pivot seat 62, a second limiting groove 6211 is provided on the side facing the connecting arm 5; the second limiting groove 6211 extends along the circumferential direction of the second pivot seat 62 and is exposed on the outside of the protective cover housing 22; on the first end 501 of the connecting arm, a second limiting post 53 is provided on the side facing the second pivot seat 62; the second limiting post 53 is embedded in the second limiting groove 6211 and can slide along the extension direction of the second limiting groove 6211 to limit the rotation amplitude of the connecting arm 5.

[0100] In this embodiment, the first limiting post 43 on the first end 401 of the drive arm engages with the first limiting groove 3211 on the first housing connection portion 321 of the first rotating shaft seat 32. The first limiting groove 3211 is an arc-shaped groove. When the first limiting post 43 rotates to both ends of the first limiting groove 3211, the drive arm 4 locks and cannot continue to move, thus controlling the maximum rotation amplitude of the drive arm 4. The second limiting post 53 on the first end 501 of the connecting arm engages with the second limiting groove 6211 on the second housing connection portion 621 of the second rotating shaft seat 62. The second limiting groove 6211 has the same shape as the first limiting groove 3211. When the second limiting post 53 rotates to both ends of the second limiting groove 6211, the connecting arm 5 locks and cannot continue to move.

[0101] In actual production, the length or curvature of the first limiting groove 3211 and the second limiting groove 6211 can be adjusted according to actual needs. For example, the first limiting groove 3211 and the second limiting groove 6211 can be a quarter-circle arc structure or a semi-circle arc structure, as long as they can limit the movement of the drive rotating arm 4 and the connecting rotating arm 5. No further restrictions are imposed here.

[0102] In other embodiments, such as Figures 7a to 9 As shown, a first weight-reducing groove 44 and a second weight-reducing groove 54 can also be provided on the drive arm 4 and the connecting arm 5, respectively. The first weight-reducing groove 44 and the second weight-reducing groove 54 can effectively reduce the weight of the drive arm 4 and the connecting arm 5. At the same time, by adjusting the size of the first weight-reducing groove 44 and the second weight-reducing groove 54, the weight of the drive arm 4 and the connecting arm 5 can be balanced. This reduces the energy consumption of the drive motor 21, thereby saving costs.

[0103] In some embodiments of this utility model, such as Figures 6a to 6d As shown. A first bearing 324 is provided within the first shaft connection through hole 323 of the first shaft seat 32; a drive shaft 31 passes through the first bearing 324 and is rotatably connected to the first shaft seat 32; a first waterproof ring 325 is also provided between the drive shaft 31 and the inner wall of the first shaft connection through hole 323; a second waterproof ring 326 is provided between the first shaft connection part 322 and the first mounting through hole 221; a second bearing 624 is provided within the second shaft connection through hole 623 of the second shaft seat 62; a connecting shaft 61 passes through the second bearing 624 and is rotatably connected to the second shaft seat 62; a third waterproof ring 625 is also provided between the connecting shaft 61 and the inner wall of the second shaft connection through hole 623; a fourth waterproof ring 626 is provided between the second shaft connection part 622 and the second mounting through hole 222.

[0104] In this embodiment, a first bearing 324 is provided between the first shaft connection through hole 323 and the drive shaft 31. The first bearing 324 can effectively reduce wear between the drive shaft 31 and the first shaft connection through hole 323. Furthermore, a first waterproof ring 325 is provided between the first shaft connection through hole 323 and the drive shaft 31, and a second waterproof ring 326 is provided between the first shaft connection portion 322 and the first mounting through hole 221. The first waterproof ring 325 and the second waterproof ring 326 can improve the problem of moisture or impurities in the external environment entering the camera housing, thereby ensuring the IP protection rating (protection rating for electrical equipment housings against foreign object intrusion) of the camera housing.

[0105] A second bearing 624 and a third waterproof ring 625 are provided between the second shaft connecting through hole 623 and the connecting shaft 61, and a fourth waterproof ring 626 is provided between the second shaft connecting part 622 and the second mounting through hole 222. The functions of the second bearing 624, the third waterproof ring 625 and the fourth waterproof ring 626 are similar to those described above, and will not be elaborated further here.

[0106] In actual production processes, such as Figure 6a As shown, snap ring mounting grooves can also be provided on the drive shaft 31 and the connecting shaft 61, and snap rings 33 can be provided in the snap ring mounting grooves, so that the outer ring of the first bearing 324 and the drive shaft 31, and the outer ring of the second bearing 624 and the connecting shaft 61 can be pressed together by snap rings 33, so as to make the fit between the shaft and the bearing more secure.

[0107] In some embodiments of this utility model, such as Figures 6a to 9 As shown. The connecting shaft 61, located inside the protective cover housing 22, has a first protrusion 611 and a second protrusion 612 spaced along its length. Both the first protrusion 611 and the second protrusion 612 extend in a direction perpendicular to the connecting shaft 61. A preset angle exists between the extending directions of the first protrusion 611 and the second protrusion 612. The position of the first protrusion 611 corresponds to the first rotation angle of the connecting arm 5 when the protective cover 1 covers the camera window 110 of the camera body 100. The position of the second protrusion 612 corresponds to the second rotation angle of the connecting arm 5 when the protective cover 1 does not cover the camera window 110 of the camera body 100. Inside the protective cover housing 22, two position sensors 7 are also provided. These two position sensors 7 cooperate with the first protrusion 611 and the second protrusion 612, respectively, and are triggered when the connecting arm 5 rotates to the first rotation angle or the second rotation angle, thereby controlling the drive motor 21 to stop rotating when the connecting arm 5 rotates to either the first or the second rotation angle.

[0108] In this embodiment, the portion of the connecting shaft 61 located inside the protective cover housing 22 is provided with a first protrusion 611 and a second protrusion 612 spaced apart along its length. The first protrusion 611 corresponds to a first rotation angle of the connecting arm 5, and the second protrusion 612 corresponds to a second rotation angle of the connecting arm 5. The first rotation angle can be the limit angle when the protective cover 1 covers the camera window 110; the second rotation angle can be the limit angle when the protective cover 1 does not cover the camera window 110.

[0109] like Figure 4 and Figure 6aAs shown, when the connecting arm 5 rotates under the drive of the protective flip cover 1 to a position covering the camera window 110, the first protrusion 611 stands upright on the front side of the position sensor 7. At this time, the position sensor 7 detects that the protective flip cover 1 has covered the camera window 110 and controls the drive motor 21 to stop rotating. Figure 5 and Figure 6b As shown, when the connecting arm 5 rotates to a position that does not cover the camera window 110 under the drive of the protective flip cover 1, the second protrusion 612 stands upright on the front side of the position sensor 7. At this time, the position sensor 7 detects that the protective flip cover 1 has moved to a position that does not cover the camera window 110, and controls the drive motor 21 to stop rotating.

[0110] In this embodiment, a first protrusion 611 and a second protrusion 612 are provided on the connecting shaft 61, so that the connecting shaft 61 can interact with the position sensor 7, thereby realizing automatic control of the position of the protective flip cover 1.

The protective cover upper shell 224 is mounted on the protective cover base 223, so that the drive module 2 and the transmission mechanism 3 are located in the accommodating space formed by the protective cover upper shell 224 and the protective cover base 223. An electrical connection port 2232 is provided on the protective cover base 223. The protective cover electrical interface 81 passes through the electrical connection port 2232 and is electrically connected to the camera body 100.
