DETAILED DESCRIPTION
[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0044] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.
[0045] Secondly, it should be noted that in the description of the present application, terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component 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 application.
[0046] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" 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 the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0048] Image acquisition devices are usually provided with a line connector so that the image acquisition device can be connected to other external devices via cables when used in specific applications. Line connectors include fixed and rotating types. Fixed line connectors are usually an integrated structure with the device housing, and their line direction is fixed. The line direction cannot be adjusted during use, and the usage scenarios are limited. Different connectors with different wiring directions need to be designed in different scenarios, which increases product costs. Rotating line connectors can rotate and change the line direction to meet the needs of different wiring scenarios. However, the current rotating line connectors are prone to displacement and swinging under the action of cable gravity or when an outsider collides with the cable connector, causing the line connector to have a deflection angle relative to the required line direction. Therefore, the current rotating line connectors of image acquisition devices have poor wiring stability.
[0049] In response to the above-mentioned problems, an embodiment of the present application provides an image acquisition device, in which a rotary joint can be rotated relative to a device body to select different wiring directions. By providing mutually cooperating limiting structures between the rotary joint and the device body, when the rotary joint is rotated to a required wiring direction after wiring, the rotary joint can be stabilized in this position by the limiting structure, thereby preventing the rotary joint from deflecting and swinging, thereby improving the stability of the wiring of the image acquisition device.
[0050] To facilitate understanding, the following first describes the applicable application scenarios of the image acquisition device provided in the embodiments of the present application.
[0051] The image acquisition device provided in the embodiment of the present application can be used in the automation equipment of a manufacturing factory, or in the handling robots or automated sorting equipment of a logistics warehouse, to identify the surrounding environment or objects. By way of example, the image acquisition device can be an industrial camera, a barcode reader, etc., and the embodiment of the present application does not specifically limit this.
[0052] Figure 1 A schematic diagram of the structure of an image acquisition device provided in an embodiment of the present application, Figure 2 The explosion of the image acquisition device provided in the embodiment of the present application Figure 1 , Figure 3 The explosion of the image acquisition device provided in the embodiment of the present application Figure 2 , Figure 4 A front view of an image acquisition device provided in an embodiment of the present application, Figure 5 for Figure 4 Sectional view along the AA direction, Figure 6 for Figure 5 Partial view of position B in the figure.
[0053] Please refer to Figures 1 to 6The present application provides an image acquisition device, which includes a device body 100 and a rotary joint 200, and the rotary joint 200 is rotatably connected to the device body 100. The cables inside the device body 100 can be led out of the device body 100 through the rotary joint 200, so as to be connected with other devices other than the image acquisition device. The rotary joint 200 can be rotated relative to the device body 100 to adjust the cable outlet direction to meet the wiring requirements in different scenarios.
[0054] The rotary joint 200 includes a housing 210 and a stopper 220. The housing 210 is provided with a receiving groove 211. The stopper 220 is movably disposed in the receiving groove 211. The notch 211a of the receiving groove 211 is located on the side of the housing 210 facing the device body 100. The stopper 220 is configured to at least partially protrude from the notch 211a to the outside of the receiving groove 211. The surface of the device body 100 is provided with a stopper 101. When the rotary joint 200 rotates to a preset position relative to the device body 100, the stopper 220 is engaged with the stopper 101.
[0055] It can be understood that the side surface of the housing 210 of the rotary joint 200 facing the device body 100 can abut against or have a gap with the corresponding surface of the device body 100, and the limiting groove 101 is recessed relative to the surface of the device body 100. When the rotary joint 200 rotates to a preset position relative to the device body 100, the limiting member 220 protrudes from the notch 211a to the outside of the rotary joint 200 and is clamped in the limiting groove 101. When the rotary joint 200 rotates relative to the device body 100 and the limiting member 220 is misaligned relative to the limiting groove 101, the limiting member 220 abuts against other positions on the surface of the device body 100, and the limiting member 220 is squeezed by the surface of the device body 100 and at least partially retracts into the inside of the accommodating groove 211.
[0056] Exemplarily, the rotation angle range of the rotary joint 200 relative to the device body 100 can be 360°, that is, the rotary joint 200 can be rotated to any position around a fixed rotation axis relative to the device body 100. The rotary joint 200 can rotate clockwise relative to the device body 100, and can also rotate counterclockwise relative to the device body 100. When the rotary joint 200 rotates relative to the device body 100, the limiter 220 can revolve with the rotary joint 200 relative to the device body 100 in the accommodating groove 211, and the movement path of the limiter 220 relative to the device body 100 is circular. When the limiter groove 101 is set on the surface of the device body 100, the limiter groove 101 can correspond to any position of the circular motion control unit of the limiter 220.
[0057] It should be noted that in the image acquisition device provided in the embodiment of the present application, a movable limit member 220 is provided on the rotary joint 200 to cooperate with the limit slot 101 on the device body 100. When the rotary joint 200 is connected and rotated to a preset position, the limit member 220 and the limit slot 101 are engaged to keep the rotary joint 200 in the preset position relative to the device body 100, thereby preventing the rotary joint 200 from deflecting and swinging, thereby improving the stability of the wiring of the image acquisition device.
[0058] Please continue to refer to Figures 1 to 6 In a possible implementation, there may be a plurality of limit grooves 101, and the plurality of limit grooves 101 are spaced apart around the rotation axis of the rotary joint 200 relative to the device body 100. The rotary joint 200 has a plurality of preset positions relative to the device body 100, and when the rotary joint 200 is located at different preset positions, the limit member 220 can be engaged with different limit grooves 101.
[0059] It is understandable that a plurality of limit slots 101 may correspond to different positions on the limit member 220 circular motion control unit, so that the rotary joint 200 has a plurality of different positions and postures relative to the device body 100, and different positions and postures may have different outlet directions, and each preset position may correspond to a position and posture, that is, each position and posture corresponds to an outlet direction. When adjusting the outlet direction of the rotary joint 200, the limit member 220 may be rotated into the corresponding limit slot 101, so that the relative position stability of the rotary joint 200 and the device body 100 can be ensured in each position and posture.
[0060] In some embodiments, the housing 210 has a cable interface 212. When the rotary joint 200 rotates to different preset positions relative to the device body 100, the cable interface 212 faces different directions. Therefore, the direction of the cable interface 212 of the image acquisition device can be adjusted according to actual wiring requirements, thereby meeting the requirements of wiring stability in different application scenarios.
[0061] Figure 7 A side view of the first state of the image acquisition device provided in an embodiment of the present application, Figure 8 A side view of the second state of the image acquisition device provided in an embodiment of the present application.
[0062] Exemplarily, the limit groove 101 can be set on the inclined surface of the outer end of the device body 100, and the shell 210 of the rotary joint 200 can be a triangular structure, that is, the cross-sectional shape of the shell 210 can be a triangle, so that the shell 210 has three side faces in addition to the two end faces, one of which is opposite to the inclined surface of the device body 100, and the cable interface 212 can be set on any one of the other two side faces. When the rotary joint 200 rotates relative to the device body 100, the side of the shell 210 opposite to the device body 100 remains parallel to the inclined surface of the device body 100, and the orientation of the cable interface 212 relative to the device body 100 can be adjusted and changed.
[0063] Define the length direction of the device body 100 as the X direction, the height direction of the device body 100 as the Y direction, the X direction is perpendicular to the Y direction, and the rotary joint 200 can be installed on the inclined surface at one end of the device body 100 along the X direction. The inclined surface is inclined 45° relative to the X direction and 45° relative to the Y direction. Exemplarily, the rotary joint 200 has two preset positions relative to the device body 100. Figure 7 As shown, when the rotary joint 200 rotates to the first preset position, the cable interface 212 can extend along the X direction. Figure 8 As shown, when the rotary joint 200 rotates to the second preset position, the cable interface 212 can extend along the Y direction. The rotary joint 200 can also be installed at other angles relative to the device body 100, which is not specifically limited in the embodiment of the present application.
[0064] It should be noted that there may be multiple cable interfaces 212, and the multiple cable interfaces 212 may extend in the same direction, or the multiple cable interfaces 212 may face different directions, which is not specifically limited in the embodiment of the present application.
[0065] In some embodiments, there may be a plurality of limit members 220, which are spaced apart around the rotation axis of the rotary joint 200 relative to the device body 100, and the plurality of limit members 220 are respectively engaged with different limit slots 101. When the rotary joint 200 rotates to a preset position relative to the device body 100, the plurality of limit members 220 can simultaneously play a limiting role, thereby improving the stability of the relative position between the rotary joint 200 and the device body 100.
[0066] Exemplarily, there may be two limit members 220, and the limit grooves 101 may be arranged in pairs, with two limit grooves 101 in each pair. The two limit members 220 may be distributed on both sides of the rotation axis of the rotary joint 200 relative to the device body 100, and the distribution interval angle of the two limit members 220 relative to the axial direction of the rotary joint 200 is 180°, and the two limit grooves 101 correspond to the two limit members 220 respectively. The rotary joint 200 has two preset positions relative to the device body 100, and the rotary joint 200 can rotate 180° relative to the device body 100 to switch between the two preset positions.
[0067] It should be noted that the number of the limiting members 220 may be two, three or more, which is not specifically limited in the embodiment of the present application, and the number of the limiting grooves 101 may be an integer multiple of the number of the limiting members 220 .
[0068] In some embodiments, a guide groove 102 is provided on the surface of the device body 100, and the guide groove 102 and the limiting groove 101 are located on the same side of the device body 100. The limiting groove 101 is opposite to the end of the guide groove 102. When the rotary joint 200 rotates relative to the device body 100 and the limiting member 220 slides out of the limiting groove 101, the limiting member 220 moves along the guide groove 102.
[0069] It is understandable that when the rotary joint 200 rotates, the guide groove 102 can provide a guiding function for the rotary joint 200, thereby improving the smoothness of the rotation of the rotary joint 200. The guide groove 102 can be in an arc shape, and the guide groove 102 can overlap with the circular motion control unit of the limiter 220, so that the limiter 220 can move along the guide groove 102 when it moves.
[0070] Exemplarily, there is a spacing between the end of the limit groove 101 and the guide groove 102. When the limit member 220 slides out of the guide groove 102 and slides into the limit groove 101, the rotating rotary joint 200 has a sense of stopping, so that the rotating joint 200 can be accurately stopped at a preset position when rotating the rotary joint 200.
[0071] Exemplarily, the limit groove 101 can be connected to the end of the guide groove 102, and the depth of the limit groove 101 can be greater than the depth of the guide groove 102. In this way, when the limit member 220 slides from the guide groove 102 to the limit groove 101, the rotating rotary joint 200 has a sense of stoppage, so that the rotary joint 200 can be accurately stopped at a preset position when rotating.
[0072] Fig. 9 An exploded view of a rotary joint in an image acquisition device provided in an embodiment of the present application.
[0073] Please refer to Fig. 9 , and combined with Figures 1 to 6 In a possible implementation, the rotary joint 200 may further include an elastic member 230, which is located in the accommodating groove 211 and abuts against the limiting member 220, and the elastic member 230 is configured to apply an elastic force toward the device body 100 to the limiting member 220 so that the limiting member 220 abuts against the device body 100.
[0074] It is understandable that the elastic member 230 can provide a pre-tightening force for the clamping fit between the stopper 220 and the stopper groove 101. When the stopper 220 is clamped with the clamping groove, it can ensure that the stopper 220 has sufficient pressure relative to the surface of the device body 100 to prevent the stopper 220 from coming out of the clamping groove.
[0075] Exemplarily, the elastic member 230 may be an elastic structure or an elastomer such as a spring, an elastic pressing plate, or rubber, and the elastic member 230 with different elastic damping may be rotated according to different application scenarios, which is not specifically limited in the embodiments of the present application.
[0076] Fig.10 A schematic diagram of the structure of a cover plate in an image acquisition device provided in an embodiment of the present application.
[0077] Please refer to Fig.10 , and combined with Figures 1 to 6 In some embodiments, the housing 210 may include a connector body 213 and a cover plate 214, and the cover plate 214 is connected to the side of the connector body 213 facing the device body 100. A boss 214a is provided on the side of the cover plate 214 facing the connector body 213, and the receiving groove 211 is provided on the boss 214a, so that the inner space of the housing 210 can be used to assemble the limiter 220, thereby improving the assembly convenience of the limiter 220.
[0078] For example, the surface of the cover plate 214 may be parallel to the inclined surface of the limiting groove 101 provided in the device body 100. The cover plate 214 may be connected to the joint body 213 by fasteners such as bolts.
[0079] For example, the boss 214 a may be an integrally formed part with the cover plate 214 , or the boss 214 a may be welded to the cover plate 214 , which is not specifically limited in the embodiments of the present application.
[0080] In some embodiments, the top of the boss 214a has a mounting opening 214b, and the mounting opening 214b can be connected to the accommodating groove 211. The rotary joint 200 can also include a baffle 240, which is blocked at the mounting opening 214b and connected to the boss 214a via a fastener 250.
[0081] Among them, when assembling the rotary joint 200, the limit member 220 can be first placed into the receiving groove 211 from the installation port 214b, and then the elastic member 230 can be placed in the receiving groove 211 to abut against the limit member 220. Thereafter, the baffle 240 is installed to abut against the elastic member 230, so that it is compressed in the receiving groove 211 and provides an elastic pre-tightening force for the limit member 220, thereby preventing the elastic member 230 and the limit member 220 from falling out of the receiving groove 211.
[0082] Exemplarily, a threaded mounting hole may be provided on the boss 214 a , and the bolt mounting hole is located on the side of the receiving groove 211 , and the baffle 240 may be connected to the threaded mounting hole on the boss 214 a by a fastener 250 such as a screw.
[0083] Illustratively, a step structure may be provided between the threaded mounting hole on the boss 214a and the receiving groove 211, and the joint of the baffle 240 matches the step structure, thereby playing a role in positioning and limiting the baffle 240 when the baffle 240 is installed.
[0084] In a possible implementation, the image acquisition device may further include a sealing ring 260 and a rotating pressure ring 270 . The device body 100 has a wiring hole 103 . The rotating pressure ring 270 is connected to the rotary joint 200 and is arranged around the wiring hole 103 . The sealing ring 260 abuts between the rotating pressure ring 270 and the rotary joint 200 .
[0085] It can be understood that an annular sealing groove surrounding the wiring hole 103 can be provided on the device body 100, and a rotating pressure ring 270 can be arranged to cooperate with the sealing groove. The rotating pressure ring 270 can make the outer shell 210 of the rotary joint 200 always press the sealing ring 260 during the rotation of the rotary joint 200, thereby ensuring good sealing between the rotary joint 200 and the device body 100.
[0086] For example, the device body 100 may include an upper cover 110 and a lower cover 120 , which are spliced with each other and fixed by fasteners such as bolts. The rotary joint 200 may be rotatably connected to the lower cover 120 .
[0087] In some embodiments, the limiting member 220 may be spherical, and the diameter of the notch 211 a is smaller than the diameter of the limiting member 220 .
[0088] It is understandable that when the rotary joint 200 rotates relative to the device, the friction between the limiter 220 and the device body 100 can be reduced, thereby improving the smoothness of rotation of the rotary joint 200 and reducing the wear on the surfaces of the limiter 220 and the device body 100.
[0089] Exemplarily, the limiting member 220 may be a steel ball, the cross-section of the limiting groove 101 may be circular, the diameter of the steel ball may be equal to or slightly smaller than the diameter of the limiting groove 101, the diameter of the notch 211a may be smaller than the diameter of the steel ball, and the steel ball may protrude to the outside of the accommodating groove 211, so that when the rotary joint 200 is rotated to a preset position, it cooperates with the limiting groove 101 on the device body 100.
[0090] It should be noted that the limit member 220 can also be made of other metals or alloys such as aluminum, or the limit member 220 can be made of a plastic material with higher strength. The embodiment of the present application does not limit the specific size value and material type of the limit member 220.
[0091] An embodiment of the present application provides an image acquisition device, including a device body and a rotary joint, which is rotatably connected to the device body; the rotary joint includes a shell and a limit member, the shell is provided with a receiving groove, and the limit member can be movably arranged in the receiving groove; the notch of the receiving groove is located on the side of the shell facing the device body; the limit member is configured to protrude at least partially from the notch to the outside of the receiving groove, and the surface of the device body is provided with a limit groove. When the rotary joint is rotated to a preset position relative to the device body, the limit member is engaged with the limit groove to avoid deviation and swing of the rotary joint, thereby improving the stability of the wiring of the image acquisition device.
[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
