Description

Technical Field

[0001] This utility model belongs to the field of inspection equipment technology, and specifically relates to a size visual inspection device based on a 3D camera. Background Technology

[0002] In the production process of automotive parts, in order to ensure that the quality of the parts meets the standards, the parts need to be stably transported to the testing equipment by a transportation device. The 3D camera on the testing equipment can then perform a detailed scan of the appearance of the parts. Then, optical imaging technology is used to fully capture detailed information such as surface contours and shape features. Based on the three-dimensional data model, the overall appearance and dimensions of the parts are accurately detected, thereby realizing a systematic evaluation of the appearance quality of the parts.

[0003] A visual 3D inspection device is disclosed in Chinese Patent Network CN222336295U. After completing the inspection of one side of a component, the device transports the component to two clamping blocks via a second electric conveyor belt. The pneumatic clamp then clamps the component under the drive of an air pump. Then, a second motor drives the pneumatic clamp and the clamped component to flip over, flipping the component onto the first electric conveyor belt and exposing the uninspected back side of the component to the field of view of the 3D inspection instrument. This allows the inspection device to comprehensively inspect the appearance and dimensions of the component.

[0004] Since the height of the clamping block is fixed, when the clamping block clamps different automotive parts and causes them to flip, if the overall height of the clamped part is relatively high, the part will come into contact with the first electric conveyor belt before the clamping block has rotated to the predetermined position. At this time, the clamping block will continue to move. This phenomenon can easily cause the part to be damaged by the squeezing of the first electric conveyor belt and the clamping block. Utility Model Content

[0005] To address the problem that taller components are easily damaged due to compression when flipping them over, this invention proposes a 3D camera-based size visual inspection device to overcome the aforementioned technical problems in existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a size visual inspection device based on a D camera, including a transport component, which is provided in two sets. A detection component is provided on the top of the transport component. A clamping component and a flipping component are provided between the two sets of transport components. The flipping component is connected to the clamping component. A lifting component is provided at the bottom of the transport component. The lifting end of the lifting component is connected to the clamping component.

[0008] The lifting assembly is used to lift the clamping assembly so that the clamping end of the clamping assembly can be adjusted according to the height of the component. One of the transport assemblies is used to transport the component to the clamping assembly so that the clamping assembly clamps the component. The flipping assembly drives the component to flip through the clamping assembly so that the component is flipped onto another transport assembly.

[0009] Furthermore, the transport assembly includes a transport frame, a plurality of transport rollers are rotatably connected inside the transport frame, a transport belt is provided on the outer side of the plurality of transport rollers, a transport motor is fixedly installed on the outer side of the transport frame, and the output end of the transport motor is fixedly connected to the transport rollers.

[0010] Furthermore, the detection component includes a mounting frame, which is fixedly mounted on the outside of the transport frame. A mounting plate is fixedly mounted on the top of the inner wall of the mounting frame, and a detection frame is fixedly connected to the bottom of the mounting plate. A camera is fixedly mounted on the inner wall of the detection frame.

[0011] Furthermore, the clamping assembly includes a support frame disposed between two transport frames. A storage frame is disposed inside the support frame, and a bidirectional screw is rotatably connected inside the storage frame. A connecting block is threaded onto the outer surface of the bidirectional screw, and a clamping plate is fixedly connected to one side of the connecting block. A clamping motor is disposed on the outer side of the support frame, and the output end of the clamping motor is fixedly connected to the bidirectional screw.

[0012] Furthermore, a T-shaped push rod is movably connected to the outer side of the clamping plate. One end of the T-shaped push rod passes through the clamping plate and is fixedly connected to an L-shaped rubber plate. A spring is fixedly connected between the other end of the T-shaped push rod and the clamping plate.

[0013] Furthermore, the flipping component includes a connecting shaft, which is fixedly connected to the back of the storage frame. The connecting shaft is rotatably connected to the support frame. One end of the connecting shaft passes through the support frame and is fixedly mounted on a rotating disk. The clamping motor is fixedly mounted on the outside of the rotating disk. A rotating groove is provided on the inner wall of the support frame. The output end of the clamping motor is fixedly connected to a bidirectional screw through the rotating groove. A flipping motor is fixedly mounted on the outside of the support frame, and the output end of the flipping motor is fixedly connected to the connecting shaft.

[0014] Furthermore, the lifting assembly includes a connecting frame, which is fixedly installed at the bottom of the two transport frames. A lifting hydraulic cylinder is fixedly installed at the bottom of the connecting frame. The output end of the lifting hydraulic cylinder passes through the connecting frame and is fixedly connected to the support frame. A guide rod is fixedly connected to the bottom of the support frame, and the guide rod is movably connected to the connecting frame.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses a lifting component to lift the clamping component, allowing the clamping end of the clamping component to be adjusted according to the height of the automotive parts. This design enables the flipping component to flip automotive parts of different heights via the clamping component. When the clamping component rotates to the predetermined position, the automotive parts also come into direct contact with the transport end of the transport component, thus avoiding the clamping component and transport component from squeezing the automotive parts and preventing damage to the automotive parts due to squeezing.

[0017] This invention uses a clamping motor, a bidirectional screw, and two connecting blocks to drive two clamping plates. These clamping plates, via a T-shaped push rod and springs, move two L-shaped rubber plates, thus clamping the automotive parts. The elastic deformation of the springs allows the L-shaped rubber plates to generate buffered displacement according to the shape of the automotive parts. This ensures reliable clamping through continuous contact friction during flipping, preventing the parts from detaching, and also keeps the clamping force within a safe threshold, effectively preventing surface damage to the automotive parts caused by rigid compression. This achieves a dual optimization of clamping reliability and workpiece protection.

[0018] 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

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a size visual inspection device based on a 3D camera, including a transport component 1. The transport component 1 is provided in two sets. A detection component 2 is provided on the top of the transport component 1. A clamping component 3 and a flipping component 4 are provided between the two sets of transport components 1. The flipping component 4 is connected to the clamping component 3. A lifting component 5 is provided at the bottom of the transport component 1. The lifting end of the lifting component 5 is connected to the clamping component 3.

[0032] The lifting component 5 is used to lift the clamping component 3 so that the clamping end of the clamping component 3 can be adjusted according to the height of the component. One of the transport components 1 is used to transport the component to the clamping component 3 so that the clamping component 3 can clamp the component. The flipping component 4 drives the component to flip through the clamping component 3 so that the component can be flipped onto another transport component 1.

[0033] When inspecting the external dimensions of automotive parts, the lifting assembly 5 lifts the clamping assembly 3, allowing the clamping end of the clamping assembly 3 to move to a suitable position according to the height of the part. The automotive part is then placed inside one of the transport assemblies 1. When the transport assembly 1 moves the part from the corresponding detection assembly 2, the detection assembly 2 detects the dimensions of the top and outer sides of the automotive part. When the automotive part moves to the clamping assembly 3, the clamping assembly 3 clamps the automotive part. Then, the flipping assembly 4 rotates the clamped automotive part, causing it to flip onto another transport assembly 1 with its bottom facing upwards. This allows the detection assembly 2 on the transport assembly 1 to detect the bottom dimensions of the automotive part.

[0034] The clamping component 3 is lifted by the lifting component 5, so that the clamping end of the clamping component 3 can be adjusted according to the height of the car parts. This setting allows the flipping component 4 to flip car parts of different heights through the clamping component 3. When the clamping component 3 rotates to the predetermined position, the car parts also come into direct contact with the transport end of the transport component 1. This avoids the clamping component 3 and the transport component 1 from squeezing the car parts, and also avoids damage to the car parts due to squeezing.

[0035] In one embodiment, the transport component 1 includes a transport frame 101, a plurality of transport rollers 102 are rotatably connected inside the transport frame 101, a transport belt 103 is provided on the outer side of the plurality of transport rollers 102, and a transport motor 104 is fixedly installed on the outer side of the transport frame 101, the output end of the transport motor 104 being fixedly connected to the transport rollers 102.

[0036] The transport motor 104 drives the transport roller 102 to rotate, and the rotating transport roller 102 drives the transport belt 103 to move inside the transport frame 101. When inspecting the dimensions of automotive parts, the automotive parts are placed directly on the transport belt 103, so that the transport belt 103 can carry the automotive parts through the inspection component 2. This setting allows for continuous inspection of batches of automotive parts.

[0037] In one embodiment, the detection component 2 includes a mounting frame 201, which is fixedly mounted on the outside of the transport frame 101. A mounting plate 202 is fixedly mounted on the top of the inner wall of the mounting frame 201, and a detection frame 203 is fixedly connected to the bottom of the mounting plate 202. A camera 204 is fixedly mounted on the inner wall of the detection frame 203.

[0038] When the automotive parts pass through the inside of the inspection frame 203 driven by the conveyor belt 103, the cameras 204 installed inside the inspection frame 203 form high-density point cloud data on the surface of the automotive parts through multispectral structured light projection or laser scanning technology. Combined with a binocular stereo vision positioning system, a three-dimensional digital model with millimeter-level precision is constructed. At the same time, the system adopts a multi-sensor fusion algorithm to perform sub-pixel-level coordinate analysis on several feature points collected. The measured model is spatially registered with the CAD reference model through the ICP (Iterative Closest Point) algorithm, and geometric parameters such as length, aperture, and surface contour are automatically extracted. Finally, an SPC (Statistical Process Control) analysis report is generated. Meanwhile, cameras 204 are installed on three sides of the inner wall of the inspection frame 203. The cooperation of several cameras 204 can collect more comprehensive appearance features of the automotive parts.

[0039] In one embodiment, the clamping assembly 3 includes a support frame 301 disposed between two transport frames 101. A storage frame 302 is disposed inside the support frame 301. A bidirectional screw 303 is rotatably connected inside the storage frame 302. A connecting block 304 is threadedly connected to the outer surface of the bidirectional screw 303. A clamping plate 305 is fixedly connected to one side of the connecting block 304. A clamping motor 306 is disposed on the outer side of the support frame 301. The output end of the clamping motor 306 is fixedly connected to the bidirectional screw 303.

[0040] After the automotive parts that have completed the top and outer inspection are moved between the two clamping plates 305 by the conveyor belt 103, the clamping motor 306 drives the bidirectional screw 303, which in turn drives the two clamping plates 305 to move through the two connecting blocks 304, and the two clamping plates 305 clamp the automotive parts. This setting allows the automotive parts to be flipped normally in the future.

[0041] In one embodiment, for the clamping plate 305, a T-shaped push rod 307 is movably connected to the outer side of the clamping plate 305. One end of the T-shaped push rod 307 passes through the clamping plate 305 and is fixedly connected to an L-shaped rubber plate 308. A spring 309 is fixedly connected between the other end of the T-shaped push rod 307 and the clamping plate 305.

[0042] Two clamping plates 305 drive two L-shaped rubber plates 308 to move via a T-shaped push rod 307 and a spring 309. When the two L-shaped rubber plates 308 come into contact with the automotive parts, the clamping plates 305 continue to move a certain distance. At this time, the T-shaped push rod 307 can move on the clamping plates 305 and stretch the spring 309. In the above configuration, the spring 309 enables the two L-shaped rubber plates 308 to flexibly clamp the automotive parts, so that the clamped automotive parts will not come off between the two L-shaped rubber plates 308 when they are flipped, and the automotive parts will not be damaged by the squeezing force generated by the two L-shaped rubber plates 308.

[0043] In one embodiment, for the aforementioned flipping assembly 4, the flipping assembly 4 includes a connecting shaft 401, which is fixedly connected to the back of the storage frame 302. The connecting shaft 401 is rotatably connected to the support frame 301. One end of the connecting shaft 401 passes through the support frame 301 and is fixedly mounted on a rotating disk 402. The clamping motor 306 is fixedly mounted on the outside of the rotating disk 402. The inner wall of the support frame 301 has a rotating groove 403. The output end of the clamping motor 306 is fixedly connected to the bidirectional screw 303 through the rotating groove 403. A flipping motor 404 is fixedly mounted on the outside of the support frame 301, and the output end of the flipping motor 404 is fixedly connected to the connecting shaft 401.

[0044] By driving the flip motor 404, the flip motor 404 drives the storage frame 302 to flip 180° via the connecting shaft 401. At the same time, the connecting shaft 401 drives the clamping motor 306 to rotate via the rotating disk 402, and causes the bidirectional screw 303 to rotate inside the rotating groove 403. The above arrangement ensures that when the storage frame 302 rotates, the clamping plate 305 on the storage frame 302 can always maintain the clamping of the automotive parts, and ensures the overall stability of the automotive parts when flipping.

[0045] In one embodiment, the lifting assembly 5 includes a connecting frame 501, which is fixedly installed at the bottom of two transport frames 101. A lifting hydraulic cylinder 502 is fixedly installed at the bottom of the connecting frame 501. The output end of the lifting hydraulic cylinder 502 passes through the connecting frame 501 and is fixedly connected to the support frame 301. A guide rod 503 is fixedly connected to the bottom of the support frame 301, and the guide rod 503 is movably connected to the connecting frame 501.

[0046] By driving the lifting hydraulic cylinder 502, the support frame 301 can be lifted. At the same time, the two clamping plates 305 are adjusted in height under the action of the support frame 301, so that the two clamping plates 305 can be adjusted according to the overall height of the automotive parts. The guide rod 503 can guide the support frame 301, so that the stability of the support frame 301 can be guaranteed during lifting. While supporting the lifting hydraulic cylinder 502, the connecting frame 501 can connect the two transport frames 101 together, so that the distance between the two transport frames 101 can be kept constant, and the automotive parts can be transferred normally from one transport frame 101 to the other transport frame 101.

[0047] Through the above technical solution, 1. The lifting component 5 lifts the clamping component 3, allowing the clamping end of the clamping component 3 to be adjusted according to the height of the automotive parts. This setting ensures that when the flipping component 4 flips automotive parts of different heights via the clamping component 3, the automotive parts directly contact the transport end of the transport component 1 when the clamping component 3 rotates to the predetermined position, thus avoiding squeezing of the automotive parts by the clamping component 3 and the transport component 1, and also preventing damage to the automotive parts due to squeezing; 2. The clamping motor 306, the bidirectional screw 303, and the two connecting blocks 304... Two clamping plates 305 are driven, which in turn move two L-shaped rubber plates 308 via a T-shaped push rod 307 and a spring 309. The two L-shaped rubber plates 308 clamp the automotive parts. The elastic deformation capability of the spring 309 allows the L-shaped rubber plates 308 to generate buffer displacement according to the shape of the automotive parts. This not only maintains reliable clamping through continuous contact friction during flipping, preventing the automotive parts from detaching, but also controls the clamping force within a safe threshold, effectively preventing surface damage to the automotive parts caused by rigid extrusion. This achieves dual optimization of clamping reliability and workpiece protection.
