[0002] Nowadays, with the development of gasoline engines, diesel engines and other engines, the use of oil pipes in production and life is becoming more and more extensive. Oil pipe joints are essential parts in the process of oil pipe connection. Usually, the oil pipe joints are fixed to the ends of the oil pipes so that the oil pipes can be stably connected to the fuel tank or other parts. The quality of the oil pipe joints is directly related to the quality of the oil pipes. Therefore, the performance requirements for oil pipe joints in the production process are getting higher and higher. After the oil pipe joints are manufactured, they are usually inspected by fully automatic image detection equipment to determine the quality of the oil pipe joints.

[0003] The fully automatic image inspection equipment includes a robotic arm, a turntable and an image detection mechanism. The robotic arm is arranged on the side of the turntable, and the image detection mechanism is arranged above the turntable. The image detection mechanism can usually be an industrial camera, an ultrasonic detection head, etc. The turntable is driven by a motor, and a plurality of fixtures are fixed on the turntable. The fixtures are provided with workstation holes with openings facing upwards. During the inspection, the robotic arm automatically picks up the oil pipe joint and places it in the workstation hole on the turntable. As the turntable rotates, the oil pipe joint will move to the image detection mechanism and achieve the purpose of inspecting the oil pipe joint.

[0004] After the equipment is installed, the installation accuracy may cause the moving track of the station hole and the detection end of the image detection mechanism to be misaligned during the rotation of the turntable, making it difficult to detect the oil pipe joint placed on the fixture. Therefore, the fixture or image detection mechanism needs to be disassembled and reinstalled to meet the detection requirements, making the convenience of oil pipe joint detection relatively low.

[0034] The following is combined with Figure 1-7 This application is described in further detail.

[0035] The present application embodiment discloses a fully automatic image detection system. Figure 1 A fully automatic image detection system includes a robot arm 1, a turntable 2 and an image detection mechanism 3. The turntable 2 is horizontally arranged and installed on the ground. The turntable 2 is driven to rotate by a motor to ensure that the turntable 2 can rotate relatively stably. The robot arm 1 is installed on the ground and is located on the side of the turntable 2. The robot arm 1 can be configured to include a movable arm and a pneumatic clamp arranged on the movable arm, so that under the swing of the movable arm, the oil pipe joint to be inspected can be conveyed to the turntable 2 by the pneumatic clamp. Of course, the robot arm 1 can also be replaced with a conveyor belt, so that the robot arm 1 can pick up the oil pipe joint to the turntable 2, and there is no restriction on the model here.

[0036] Reference Figure 1 and Figure 2The turntable 2 is provided with a plurality of mounting holes 21, which are evenly distributed around the axis of the turntable 2. A clamp 4 is slidably arranged in the mounting hole 21, so that the clamp 4 can slide in the mounting hole 21 along the radial direction of the turntable 2. An adjustment component 5 is also arranged in the mounting hole 21, and the adjustment component 5 can adjust the position of the clamp 4 and lock the clamp 4. A station hole 41 is provided on the clamp 4, so that the oil pipe joint delivered to the turntable 2 can be installed in the station hole 41.

[0037] The image detection mechanism 3 is mounted above the turntable 2 through a frame. The image detection mechanism 3 can be set as an industrial camera or an ultrasonic detection head or other detection equipment, so that the image detection mechanism 3 can detect the oil pipe joint to more accurately judge the quality of the oil pipe joint.

[0038] During the inspection, the mechanical arm 1 automatically picks up the oil pipe joint and places it in the workstation hole 41 on the turntable 2. As the turntable 2 rotates, the oil pipe joint moves to the image detection mechanism 3 and the purpose of inspecting the oil pipe joint is achieved. In addition, during the equipment installation process, the position of the clamp 4 can be adjusted more conveniently through the adjustment component 5, so that the moving track of the oil pipe joint corresponds to the image detection mechanism 3. At this time, there is no need to disassemble and reinstall the clamp 4 and the image detection mechanism 3, which improves the convenience of the oil pipe joint inspection process.

[0039] Reference Figure 1 and Figure 2 The adjustment assembly 5 includes a plurality of adjustment screws 51 and a plurality of adjustment nuts 52. Specifically, two adjustment screws 51 are arranged inside the same mounting hole 21. Both adjustment screws 51 extend along the sliding direction of the clamp 4 and penetrate the clamp 4. Both ends of the adjustment screws 51 are fixed to the inner wall of the mounting hole 21 by screws. The adjustment nut 52 is sleeved and threadedly connected to the adjustment screw 51, and the adjustment nut 52 is rotatably connected to the clamp 4.

[0040] Rotating the adjusting nut 52 can pull the clamp 4 to slide along the adjusting screw 51, thereby achieving the purpose of adjusting the position of the clamp 4. In addition, setting two adjusting screws 51 on the same clamp 4 can improve the limiting effect of the clamp 4, so that the clamp 4 is more stable when sliding and in use.

[0041] In other embodiments, the adjusting screw 51 may be provided as one, in which case a guide groove is provided on the side wall of the mounting hole 21, and the side of the clamp 4 is clamped and slidably connected to the guide groove, so that the clamp 4 also has better stability during adjustment and use. In addition, the adjusting component 5 may also be provided as a locking screw, which is passed through and threadedly connected to the clamp 4, and is pressed against the side wall of the mounting hole 21.

[0042] Reference Figure 2, the station hole 41 vertically penetrates the fixture 4. The lower end surface of the turntable 2 is in contact with the bottom plate 6, and the bottom plate 6 stands on the ground through a bracket, so that the bottom plate 6 can close the opening at the lower end of the station hole 41. At this time, the bottom plate 6 is provided with a discharge hole 61, and the aperture of the discharge hole 61 is larger than the aperture of the station hole 41. Specifically, the discharge hole 61 is set as a long hole and extends in the radial direction of the turntable 2. When the turntable 2 rotates, the station hole 41 will pass through the discharge hole 61, so that the oil pipe joint that has been tested in the station hole 41 can fall down from the discharge hole 61.

[0043] A discharge track 7 is installed below the discharge hole 61, so that the dropped oil pipe joint can be smoothly discharged through the discharge track 7, achieving the purpose of automatic and rapid discharge, and further improving the convenience of the oil pipe joint detection process.

[0044] Reference Figure 2 and Figure 3 At the same time, the end of the discharge track 7 facing the discharge hole 61 is covered with a buffer layer 8, which is made of elastic material, such as rubber, silicone or sponge. When the oil pipe joint falls from the turntable 2 to the discharge track 7, the oil pipe joint will fall on the buffer layer 8, and then the impact on the oil pipe joint is reduced by the buffer layer 8, reducing the possibility of damage to the oil pipe joint and the discharge track 7.

[0045] Reference Figure 3 and Figure 4 The discharge track 7 is provided with a plurality of insertion holes 71 , and the buffer layer 8 is provided with a plurality of plug-in posts 81 , which are plugged and matched with the insertion holes 71 .

[0046] Reference Figure 5 and Figure 6 A snap-in pin 72 is disposed on the side wall of the socket 71 and is slidably connected thereto. A push spring 73 is installed on the side wall of the socket 71. The two ends of the push spring 73 are respectively connected to the snap-in pin 72 and the side wall of the socket 71, so that the push spring 73 can drive the snap-in pin 72 to automatically slide toward the inside of the socket 71.

[0047] Reference Figure 4 and Figure 6 The outer wall of the plug post 81 is provided with a snap-in groove 811, so that the snap-in pin 72 can be snap-into the snap-in groove 811. Specifically, a push inclined surface can be provided at the upper end of the snap-in pin 72, so that when the plug post 81 is inserted into the socket 71, the snap-in pin 72 can be pushed out of the way by itself; or a slope can be provided at the lower end of the plug post 81 to achieve the purpose of pushing the snap-in pin 72 out of the way.

[0048] Reference Figure 7A control lever 74 is rotatably arranged at the bottom of the discharge track 7, and a plurality of clamping pins 72 are fixed with traction ropes 75, and one end of the traction rope 75 away from the clamping pin 72 is fixed to the peripheral side of the control lever 74. In addition, the control lever 74 is also coaxially sleeved with a return torsion spring 741, and the two ends of the return torsion spring 741 are respectively connected to the discharge track 7 and the control lever 74.

[0049] During installation, the buffer layer 8 is covered on the discharge track 7, and the plug-in column 81 is inserted into the plug hole 71, so that the clamping pin 72 is clamped in the clamping groove 811 on the plug-in column 81, thereby locking the plug-in column 81, and improving the stability of the installation of the buffer layer 8. When the buffer layer 8 needs to be removed and replaced, it is only necessary to rotate the control lever 74 to simultaneously reel in multiple traction ropes 75, thereby pulling multiple clamping pins 72 away from the plug-in column 81, and simultaneously unlocking multiple plug-in columns 81, so as to facilitate the removal of the buffer layer 8 from the discharge track 7. In addition, the reset torsion spring 741 facilitates the reset of the driving control lever 74, and then facilitates the push spring 73 to push the clamping pin 72 to reset, so that the plug-in column 81 can be clamped again later, ensuring that the subsequent use effect is also better.

[0050] The implementation principle of a fully automatic image detection system in the embodiment of the present application is as follows: during detection, the mechanical arm 1 automatically picks up the oil pipe joint and places it in the workstation hole 41 on the turntable 2. As the turntable 2 rotates, the oil pipe joint will move to the image detection mechanism 3 and achieve the purpose of detecting the oil pipe joint. In addition, during the installation of the equipment, the position of the clamp 4 can be adjusted more conveniently through the adjustment component 5, so that the moving trajectory of the oil pipe joint corresponds to the image detection mechanism 3. At this time, there is no need to disassemble and reinstall the clamp 4 and the image detection mechanism 3, which improves the convenience of the oil pipe joint detection process.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
