Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a detection device. Background Technology

[0002] In the field of industrial automation inspection, vision sensors are widely used in workpiece identification, dimensional measurement, and appearance inspection. To ensure inspection accuracy, vision sensors are typically fixedly mounted on a bracket, and visual acquisition of different inspection areas or different workpiece models is achieved by adjusting the sensor's mounting position and angle. However, when the object to be inspected changes, it is often necessary to remove the vision sensor from the bracket, readjust the distance between it and the workpiece, and then reinstall it. This adjustment process has poor positioning repeatability and is prone to accumulating installation errors due to repeated installation and disassembly, thus affecting inspection accuracy. Utility Model Content

[0003] One objective of this invention is to provide a detection device that addresses the technical problem of reducing accuracy loss due to repeated disassembly and reassembly of visual sensors.

A first fastener is connected between the first guide rail and the first connector to lock the first connector.

[0006] Optionally, the first connector includes a first base and a set of first clamping parts disposed opposite to each other. The first base is used to mount the sensor, the set of first clamping parts is disposed on the first base, the first guide rail passes through the set of first clamping parts, and the first fastener is connected to the set of first clamping parts so that the set of first clamping parts clamps the first guide rail.

[0007] Optionally, the first clamping part is elastic, with one end of the first clamping part fixedly connected to the first base and the other end extending away from the base; The first fastener is connected to a set of first clamping parts, causing the set of first clamping parts to elastically deform in a direction that brings them closer together to clamp the first guide rail.

[0008] Optionally, the first clamping part has a receiving channel that matches the first guide rail on the side facing another first clamping part, and the first guide rail passes through multiple receiving channels, with the inner wall of the receiving channel clamping the first guide rail.

[0009] Optionally, the fixing component also includes: The second guide rail is disposed on the bracket assembly and extends along a third direction; the first guide rail is disposed on the second guide rail. The second connector is connected to the second guide rail in a third direction, and the first guide rail passes through the second connector in a second direction.

[0010] Optionally, the second connector includes: Second matrix; A set of second clamping parts, the set of second clamping parts are disposed opposite to each other on the second base along the second direction, the set of second clamping parts clamp the first guide rail; A third clamping part and a second clamping part are disposed opposite each other in the third direction on the second base, and the third clamping part clamps the second guide rail.

The sensor is used to detect the quality of the workpiece to be tested. The sensor is mounted on the fixing assembly. The stage is used to place the workpiece to be tested. The fixing assembly and / or the stage are slidably mounted on the support assembly along a first direction via the sliding members.

[0015] In practical applications, by incorporating a sliding component, the fixed assembly and / or the stage can slide relative to the support assembly along a first direction. This allows for position adjustments to be made simply by moving the sliding component when the distance between the sensor and the stage needs adjustment, eliminating the need to disassemble the sensor or reinstall the support. During actual use, when inspecting workpieces of different sizes or heights, the operator can quickly adjust the distance between the sensor and the workpiece by sliding the fixed assembly or stage, ensuring the visual acquisition position is always within the optimal focal length range. Because the sliding component guides movement along a preset direction, it avoids the accumulation of installation errors caused by repeated disassembly and reassembly, as well as the need to re-determine the sensor angle. This significantly improves the sensor's positioning repeatability and detection accuracy, while reducing adjustment time and manual operation intensity, thus enhancing the adaptability and production efficiency of the detection device.

[0019] 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 without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 2 As shown, Figure 1 This is a schematic diagram of the detection device provided in an embodiment of the present invention; Figure 2 This is provided by the embodiment of the present utility model. Figure 1 A magnified view of a portion of region A in the middle.

[0021] This utility model provides a detection device, including: a support assembly 20, a sensor 30, a fixing assembly 40, a platform 50, and multiple sliding members. The sensor 30 is used to detect the quality of the workpiece to be detected. The sensor 30 is installed on the fixing assembly 40. The platform 50 is used to place the workpiece to be detected. The fixing assembly 40 and / or the platform 50 are slidably disposed on the support assembly 20 along a first direction 60 via the sliding members.

[0022] In practical applications, by setting up a sliding component, the fixed component 40 and / or the stage 50 can slide relative to the support assembly 20 along the first direction 60. Therefore, when the distance between the sensor 30 and the stage 50 needs adjustment, only the sliding component needs to be moved to complete the position adjustment, without disassembling the sensor 30 or reinstalling the support. During actual use, when inspecting workpieces of different sizes or heights, the operator can quickly adjust the distance between the sensor 30 and the workpiece by sliding the fixed component 40 or the stage 50, ensuring that the visual acquisition position is always within the optimal focal length range. Because the sliding component guides the movement along a preset direction, it avoids the problem of accumulated installation errors caused by repeated disassembly and reassembly, as well as the need to redetermine the angle of the sensor 30. This significantly improves the positioning repeatability and detection accuracy of the sensor 30, while reducing adjustment time and manual operation intensity, thus improving the adaptability and production efficiency of the detection device.

[0023] In one embodiment, reference is made to Figure 1 The bracket assembly 20 has a slide groove 21, and the sliding member slides in the slide groove 21.

[0024] In this embodiment, the bracket assembly 20 is constructed using multiple aluminum profiles, which are connected by welding. The aluminum profiles have a groove 21 along their length. One end of the sliding member is fixedly connected to the platform 50 or the fixing assembly 40, and the other end slides in the groove 21. The sliding member is threaded with a bolt. By tightening the bolt, the bolt is pressed against the inner wall of the groove 21 or the bracket assembly 20 to lock the position of the sliding member. When the position of the sensor 30 needs to be adjusted, the bolt on the fixing assembly 40 or the platform 50 is loosened to adjust the position of the sensor 30. After adjustment, the bolt is tightened to lock the position.

[0025] In one embodiment, see Figure 1 and Figure 2 The fixing component 40 includes: The first guide rail 41 extends along the second direction 70 and is disposed on the bracket assembly 20; The first connector 42 is movably mounted on the first guide rail 41 and is used to mount the sensor 30. The first fastener 43 is connected between the first guide rail 41 and the first connector 42 to lock the first connector 42.

[0026] In practical applications, by providing a first guide rail 41 extending along the second direction 70 in the fixed component 40, and allowing the first connecting member 42 to be movably installed along this guide rail, the sensor 30 can be precisely linearly positioned in the second direction 70. Furthermore, the first connecting member 42 can rotate on the first guide rail 41 to adjust the detection angle of the sensor 30. When installing or adjusting the sensor 30, the operator only needs to slide the first connecting member 42 along the guide rail direction to achieve fine-tuning, ensuring that the center of the sensor 30's field of view is accurately aligned with the area to be detected. After the position adjustment is complete, the first connecting member 42 is locked to the first guide rail 41 by the first fastener 43, effectively preventing the sensor 30 from shifting its position due to vibration or external force during detection.

[0027] Further, see Figure 2 and Figure 3 The first connector 42 includes: The first substrate 421 is used to mount the sensor 30; A set of first clamping parts 422 are arranged opposite to each other. The set of first clamping parts 422 are disposed on the first base 421. The first guide rail 41 passes through the set of first clamping parts 422. The first fastener 43 is connected to the set of first clamping parts 422 so that the set of first clamping parts 422 clamps the first guide rail 41.

[0028] In practical applications, a first base 421 for mounting the sensor 30 is provided, and a set of opposing first clamping parts 422 are formed on it, allowing the first guide rail 41 to pass through the clamping parts, thus enabling the first connecting member 42 to slide smoothly along the guide rail direction. When the operator adjusts the position of the sensor 30, the enclosing structure of the clamping parts on the guide rail effectively limits the wobbling and tilting of the first connecting member 42, ensuring the smoothness and guiding accuracy of the sliding process. When locking is required, the first fastener 43 generates a clamping force on the set of clamping parts, which can radially clamp the guide rail to achieve high-friction locking, ensuring that the position of the sensor 30 is firmly fixed. This structure combines guiding and clamping functions, improving the stability and accuracy of the guide rail sliding fit on the one hand, and preventing the sensor 30 from shifting due to vibration after locking on the other hand, thereby further improving the positioning reliability and detection accuracy of the detection device.

[0029] Optionally, see Figure 3 The first clamping part 422 is elastic, one end of the first clamping part 422 is fixedly connected to the first base 421, and the other end extends away from the base; The first fastener 43 is connected to a set of first clamping parts 422, so that the set of first clamping parts 422 elastically deforms in a direction that moves closer to each other to clamp the first guide rail 41.

[0030] In practical applications, by making the first clamping part 422 elastic, and fixing one end of it to the first base 421 while extending the other end away from the base, the first clamping part 422 has a certain degree of opening in its natural state. When the first fastener 43 is connected to a set of first clamping parts 422, tightening the fastener will drive the two clamping parts to move closer together and undergo elastic deformation, thereby forming a reliable clamping force on the outside of the guide rail. This structure uses elastic deformation to achieve adjustable clamping of the guide rail, so that the magnitude of the clamping force can be precisely controlled by the degree of tightening of the fastener, avoiding the problems of guide rail surface wear or inconvenient assembly and disassembly caused by rigid clamping structures. At the same time, the elastic clamping can automatically compensate for the gap when subjected to vibration or temperature changes, maintaining the fit stability between the guide rail and the clamping part, thereby improving the stability of the sensor 30 installation position and the detection accuracy.

[0031] In this embodiment, the first clamping part 422 is a metal material capable of elastic deformation, and the spacing between the relative first clamping parts 422 is slightly larger than the outer diameter of the first guide rail 41, so that the first clamping part 422 can clamp the first guide rail 41 by undergoing a slight elastic deformation.

[0032] Optionally, see Figure 3The first clamping part 422 has a receiving channel 4221 that matches the first guide rail 41 on the side facing the other first clamping part 422. The first guide rail 41 passes through the multiple receiving channels 4221, and the inner wall of the receiving channel 4221 clamps the first guide rail 41.

[0033] In practical applications, by opening a receiving channel 4221 matching the first guide rail 41 on the side of the first clamping part 422 facing another first clamping part 422, the first guide rail 41 can pass through multiple receiving channels 4221 and be positioned and clamped by the inner wall of the receiving channel 4221. This structure uses the receiving channel 4221 to cover and limit the guide rail. Compared with the structure of clamping only by a plane, it can form a uniform support and friction force distribution on multiple sides of the guide rail, thereby effectively preventing the guide rail from shaking or deflecting after being subjected to force, and improving the fit stability between the guide rail and the first connecting member 42. At the same time, the geometry of the receiving channel 4221 matches the guide rail, allowing the guide rail to self-guide into the assembly process, reducing the alignment difficulty during installation and improving assembly efficiency. After the guide rail is clamped by the inner wall of the receiving channel 4221, it can maintain a stable fit when the guide rail is subjected to external vibration or impact, preventing the sensor 30 installation angle from shifting slightly, thereby improving the positioning repeatability and detection accuracy of the detection device.

[0034] In this embodiment, the first guide rail 41 has a circular cross-section, and the receiving channel 4221 is semi-circular. The two receiving channels 4221 can be joined together to form a complete circle. In other embodiments of this application, the two receiving channels 4221 can be joined together to form a shape that is the same as or similar to the cross-sectional shape of the first guide rail 41.

[0035] In one embodiment, reference is made to Figure 2 and Figure 3 The fixing component 40 also includes: The second guide rail 44 is disposed on the bracket assembly 20. The second guide rail 44 extends along the third direction 80. The first guide rail 41 is disposed on the second guide rail 44. The second connector 45 is connected to the second guide rail 44 along the third direction 80, and the first guide rail 41 passes through the second connector 45 along the second direction 70.

[0036] In practical applications, by setting a second guide rail 44 on the support assembly 20 and extending the second guide rail 44 along the third direction 80, while setting the first guide rail 41 on the second guide rail 44, the fixing assembly 40 becomes adjustable in both the second direction 70 and the third direction 80. This structure allows the first guide rail 41 to slide relative to the second guide rail 44, thereby driving the first connector 42 and sensor 30 mounted on the first guide rail 41 to achieve multi-dimensional position adjustment in space. Through this combination of dual guide rail structures, on the one hand, the relative position between the sensor 30 and the workpiece to be detected can be adjusted within a wider range to meet the requirements of different detection angles and detection ranges; on the other hand, through the cooperation between the second guide rail 44 and the second connector 45, fine displacement along the third direction 80 can be achieved, thereby realizing position reconstruction without disassembling the sensor 30 and significantly improving the position adjustment efficiency.

[0037] Furthermore, referring to Figure 2 and Figure 3 The second connector 45 includes: Second matrix 451; A set of second clamping parts 452 are disposed opposite to each other on the second base 451 along the second direction 70, and the set of second clamping parts 452 clamps the first guide rail 41; A third clamping part 453 and a second clamping part 452 are disposed opposite to each other on the second base 451 along a third direction 80, and the third clamping part 453 clamps the second guide rail 44.

[0038] In practical applications, by providing a second clamping part 452 and a third clamping part 453 in the second connector 45, which are respectively used to clamp the first guide rail 41 and the second guide rail 44, the second connector 45 can simultaneously achieve stable positioning and detachable adjustment in different directions. Specifically, a set of second clamping parts 452 are arranged opposite to each other along the second direction 70 and clamp the first guide rail 41, allowing the first guide rail 41 to slide and adjust along the second direction 70 on the second connector 45; at the same time, a set of third clamping parts 453 are arranged opposite to each other along the third direction 80 and clamp the second guide rail 44, allowing the second connector 45 to slide along the second guide rail 44 in the third direction 80. This structure achieves independent positioning and guidance of the two guide rails through two sets of mutually perpendicular clamping parts, enabling the sensor 30 to perform smooth and precise pose adjustment in a two-dimensional plane.

[0039] Furthermore, this double-layer clamping design effectively disperses the forces between the guide rails, reducing deformation or jamming caused by unidirectional clamping and improving sliding stability and guiding accuracy. By integrating two sets of orthogonal guide rail clamping mechanisms within the same structure, not only is the multi-dimensional adjustability of the sensor 30 mounting position achieved, but also the independence and reliable repeatability of sliding in each direction are guaranteed, thereby enhancing the spatial adjustment flexibility and detection accuracy of the detection device.

[0040] In this embodiment, the first direction 60 is the height direction, and the second direction 70 and the third direction 80 are perpendicular to each other.

[0041] In one embodiment, reference is made to Figure 2 The sensor 30 is slidably connected to the fixed component 40 along the second direction 70.

[0042] In practical applications, the sensor 30 is slidably connected to the fixed assembly 40 along the second direction 70, allowing the sensor 30 to be precisely positioned relative to the support assembly 20 in the second direction 70. With this structure, operators can directly translate the sensor 30 along the second direction 70 according to the size of different workpieces or the positional requirements of the detection area, without disassembling or reinstalling the sensor 30, thus quickly changing the visual acquisition position.

[0043] The travel distance of sensor 30 can cover a wide detection range, adapt to the detection needs of different models or specifications of workpieces, and improve the versatility and flexibility of the detection device.

[0044] In this embodiment, the sensor 30 is moved and mounted on the bracket assembly 20 via an electric slide. In other embodiments of this application, the sensor 30 can also be driven to move by a power source such as a ball screw structure, a motor, or a cylinder.

[0045] In one embodiment, reference is made to Figure 1 The support assembly 20 includes a base 22 and a frame 23. The base 22 is disposed at the bottom of the frame 23 to support the frame 23. The fixing assembly 40 and / or the shelf 50 are slidably disposed on the frame 23 along the first direction 60 via a sliding member.

[0046] In practical applications, the support assembly 20 supports the frame 23 via feet 22, providing a stable foundation and ensuring the overall structural stability and rigidity when the fixing assembly 40 and the shelf 50 slide in the first direction 60. The fixing assembly 40 and the shelf 50 are mounted on the frame 23 along the first direction 60 via sliding members, allowing operators to flexibly adjust the positions of the sensor 30 and the shelf 50 in the first direction 60 without disassembling or moving the entire support assembly 20.

[0047] This structure enables rapid adjustment of the relative position of the sensor 30 and the workpiece in the first direction 60, adapting to the inspection needs of workpieces of different specifications or models. Simultaneously, it maintains the overall stability and positioning accuracy of the support assembly 20, preventing vibration or displacement of the support from affecting the inspection results. The combination of the foot 22 support and the frame 23 effectively bears and disperses the friction, torque, or other external forces generated during sliding, ensuring smooth and safe sliding operation. Furthermore, it ensures that after adjustment, the fixing assembly 40 and the platform 50 can be securely locked, achieving reliable repeatable positioning.

[0048] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0049] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0050] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
