Description

Technical Field

[0001] The present invention relates to the technical field of sealing ring detection, in particular to a sealing ring detection device. Background Art

[0002] As a key sealing component in the industrial field, sealing rings are widely used in the automotive, aerospace, petrochemical, machinery manufacturing and other industries to prevent the leakage of liquids or gases and ensure the reliability and safety of equipment operation. With the development of industrial technology, the performance requirements for sealing rings are constantly improving. Their quality is directly related to the service life and safety of the equipment. After the sealing rings are produced and formed, the appearance and size of the sealing rings need to be inspected to check whether the sealing rings meet the required quality standards.

[0003] When inspecting the appearance and size of the sealing ring, the sealing ring is transferred to the bottom of the inspection component, and the camera inspection module on the universal inspection component performs irradiation inspection on the sealing ring. However, when the sealing ring is transferred to the bottom of the inspection component, the fixture for placing the sealing ring lacks sufficient correction limits on the fixed block. During the transfer process, it is easy for the fixture and the sealing ring above to deviate from the inspection position. When the inspection module performs irradiation inspection on the sealing ring, since the sealing ring is not in the optimal inspection position, the image captured by the camera inspection module will be deviated, which will lead to errors in the judgment of the appearance and size of the sealing ring, thereby affecting the quality and accuracy of the inspection.

[0038] The correction mechanism 2 is arranged above the support platform 1. The correction mechanism 2 includes a limit column 201 and a correction plate 202 located above the rotating plate 108. A fixing bar 203 is fixedly installed on the bottom surface of the correction plate 202. The correction mechanism 2 is used to fix and correct the placement jig 4;

[0039] Specifically, such as Figure 1-Figure 4As shown, two support frames 106 are provided, and the bottom surfaces of the two support frames 106 are fixedly connected to the top surface of the support platform 1. The two support frames 106 are fixedly installed with motors 107 close to each other on the side, and the upper end of the output rod of the motor 107 is fixedly connected to the bottom surface of the rotating plate 108. Two fixed blocks 109 are provided, and the bottom surfaces of the two fixed blocks 109 are fixedly connected to the top surface of the rotating plate 108.

[0040] In this embodiment: the motor 107 is fixed by the support frame 106, and the rotating plate 108 and two fixed blocks 109 are provided, so that after the placement jig 4 and the sealing ring on one fixed block 109 are inspected, the rotating plate 108 drives the other fixed block 109 and the sealing ring on the placement jig 4 to be quickly transferred to the bottom of the inspection component 103 for inspection, and the time for replacing the sealing ring in the middle is short, thereby improving the inspection efficiency.

[0041] Specifically, such as Figures 1-8 As shown, there are multiple limit columns 201 and correction plates 202, the lower ends of multiple limit columns 201 are fixedly connected to the top surface of the fixed block 109, the bottom surfaces of multiple correction plates 202 are slidably connected to the top surface of the fixed block 109, and the outer walls of multiple limit columns 201 are slidably connected to the outer wall of the placement fixture 4.

[0042] In this embodiment, the outer wall of the placement jig 4 is clamped and fixed by providing a plurality of correcting plates 202 , so that the placement jig 4 and the sealing ring are not easily offset, and the placement jig 4 and the sealing ring are ensured to be in the middle of the fixing block 109 .

[0043] Specifically, such as Figures 1-8 As shown, a plurality of through slots 204 are provided through the top surface of the fixed block 109 and the top surface of the rotating plate 108. The side surface of the fixed bar 203 is slidably connected to the inner wall of the through slot 204. A limiting plate 205 is fixedly installed on the lower end of the fixed bar 203. The top surface of the limiting plate 205 is slidably connected to the bottom surface of the rotating plate 108.

[0044] In this embodiment, the fixing bar 203 is limited by the through slot 1 204 , so that the fixing bar 203 moves more stably, and the limiting plate 205 is provided to limit the fixing bar 203 in the vertical direction.

[0045] Specifically, such as Figures 1-8 As shown, a fixed column 206 is fixedly installed on the bottom surface of the limit plate 205, and a rotating shaft 207 is rotatably installed on the bottom surface of the rotating plate 108 through a bearing seat. A circular plate 208 is fixedly installed on the lower end of the rotating shaft 207, and a plurality of arc grooves 209 are opened through the top surface of the circular plate 208. The inner wall of the arc groove 209 is slidably connected to the outer wall of the lower end of the fixed column 206.

[0046] In this embodiment: a rotating shaft 207 is rotatably installed on the bottom surface of the rotating plate 108 through a bearing seat, so that the rotating shaft 207 can rotate and drive the circular plate 208 to rotate, and the inner wall of the arc groove 1 209 is slidably connected to the outer wall of the lower end of the fixed column 206, so that the arc groove 1 209 drives the fixed column 206 to move.

[0047] Specifically, such as Figures 1-8 As shown, a connecting block 210 is fixedly installed on the outer wall of the circular plate 208, and an arc-shaped groove 211 is opened through the top surface of the connecting block 210. An adjusting column 212 is slidably installed on the inner wall of the arc-shaped groove 211. A T-shaped block 213 is fixedly installed on the upper end of the adjusting column 212. A T-shaped groove 214 is opened on the bottom surface of the rotating plate 108. The outer wall of the T-shaped block 213 is slidably connected to the inner wall of the T-shaped groove 214, and the side surface of the T-shaped block 213 is elastically connected to the inner wall of one side of the T-shaped groove 214 through an elastic member 215.

[0048] In this embodiment, the T-shaped block 213 is limited by the T-shaped slot 214, the elastic member 215 applies elastic force to the T-shaped block 213, and the adjusting column 212 and the arc-shaped slot 211 are provided. When the adjusting column 212 moves, the rotating plate 108 is driven to rotate a certain angle.

[0049] Specifically, such as Figures 1-8 As shown, a support plate 217 is fixedly installed on the top surface of the support frame 106, and a round frame 216 is fixedly installed on the side of the support plate 217. A groove body 218 is opened on the top surface of the round frame 216, and an adjustment groove 219 is opened on the inner wall of one side of the groove body 218. The outer wall of the lower end of the adjustment column 212 is slidably connected with the inner wall of the groove body 218 and the inner wall of the adjustment groove 219.

[0050] In this embodiment: by providing the groove body 218 and the adjustment groove 219, when the adjustment column 212 rotates from the inside of the groove body 218 to the adjustment groove 219, under the elastic force of the elastic member 215, the T-shaped block 213 and the adjustment column 212 are driven to move, and the adjustment column 212 moves to the inner wall of the adjustment groove 219. At this time, the correction plates 202 are away from each other, so as to facilitate the placement and removal of the placement jig 4. When the adjustment column 212 rotates and rotates out from the inner wall of the adjustment groove 219, the adjustment column 212 moves, and at this time drives the correction plates 202 to move closer to each other to correct and fix the placement jig 4, and transfer the placement jig 4 and the sealing ring to the bottom of the detection component 103 for detection.

[0051] The stabilizing mechanism 3 is arranged above the support platform 1. The stabilizing mechanism 3 includes a rotating bar 302 located above the correcting plate 202. An airbag 305 is arranged below the rotating bar 302. The stabilizing mechanism 3 is used to squeeze and fix the placement fixture 4.

[0052] Specifically, such as Figures 1-9As shown, a mounting groove 301 is opened on the outer wall of the limiting column 201, and a connecting shaft 303 is fixedly installed on the top surface of one end of the rotating bar 302. Both ends of the connecting shaft 303 are rotatably connected to the inner wall of the mounting groove 301 through a bearing seat.

[0053] In this embodiment, the two ends of the connecting shaft 303 are rotatably connected to the inner wall of the mounting groove 301 through the bearing seat, so that the connecting shaft 303 and the rotating bar 302 can rotate to a certain angle.

[0054] Specifically, such as Figures 1-9 As shown, a fixing groove 304 is opened on the bottom surface of the other end of the rotating bar 302, the inner wall of the fixing groove 304 is fixedly connected to the outer wall of the airbag 305, and the outer wall of the airbag 305 is slidably connected to the top surface of the placement fixture 4.

[0055] In this embodiment, the airbag 305 is fixed by the fixed groove 304. When the airbag 305 rotates to the top of the placement jig 4, the airbag 305 is squeezed. The airbag 305 also squeezes the top surface of the placement jig 4, making the placement jig 4 more stable and not easy to shift.

[0056] Specifically, such as Figures 1-9 As shown, an adjusting rod 307 is fixedly installed on the top surface of the correcting plate 202, and a second through slot 306 is opened through the top surface of the rotating bar 302, and the inner wall of the second through slot 306 is slidably connected to the outer wall of the upper end of the adjusting rod 307.

[0057] In this embodiment: through the provided adjustment rod 307 and the second through slot 306, when the correcting plate 202 clamps and fixes the placement jig 4, the correcting plate 202 drives the rotating bar 302 to rotate through the adjustment rod 307 and the second through slot 306, and drives the airbag 305 to rotate to the top of the placement jig 4 to squeeze and fix the placement jig 4. When the correcting plate 202 moves away from the placement jig 4, the rotating bar 302 drives the airbag 305 to rotate to its original position, and no longer squeezes and fixes the placement jig 4.

[0058] The specific solution is as follows: the sealing ring is placed on the placement jig 4, transported to the desired position by the loading component 101, and the placement jig 4 is sucked and moved to the positioning component 102 by the conveying component 105. Then the conveying component 105 transports the placement jig 4 and the sealing ring on the positioning component 102 to the middle of the limiting column 201 on the fixed block 109, and the motor 107 is turned on to drive the rotating plate 108, the fixed block 109, the placement jig 4 and the sealing ring to rotate. At this time, the rotating plate 108 drives the adjusting column 212 to rotate through the T-shaped block 213, and the adjusting column 212 rotates and rotates out of the inner wall of the adjusting groove 219 to the groove body. In 218, the adjusting column 212 moves, and the adjusting column 212 cooperates with the arc groove 211 to drive the connecting block 210 and the circular plate 208 to rotate a certain angle. The circular plate 208 drives the fixed column 206, the limit plate 205 and the fixed bar 203 to move through the arc groove 1 209. The fixed bar 203 drives the correcting plate 202 to approach each other to correct the placement of the jig 4, so that the placement jig 4 is in the middle position of the fixed block 109. At the same time, when the correcting plates 202 approach each other to correct the placement of the jig 4, the correcting plate 202 drives the adjusting rod 307 to move, and the adjusting rod 307 cooperates with the through slot 2 306 to drive the rotating bar 30 2 is rotated to a certain angle, and the rotating bar 302 drives the airbag 305 to rotate to a certain angle. The airbag 305 rotates to the top of the placement jig 4, and the airbag 305 is squeezed with the top surface of the placement jig 4. Under the reaction force of the airbag 305, the top surface of the placement jig 4 is squeezed and fixed, so that the placement jig 4 is not easy to deviate and shake. When the placement jig 4 and the sealing ring above it are rotated to the bottom of the detection component 103, it is not easy to deviate from the position. The image captured by the camera detection module on the detection component 103 will not be deviated, thereby improving the accuracy of the appearance and size detection of the sealing ring. After the detection of the detection component 103 is completed, the motor 107 drives the rotating plate 108 and the placement jig 4 and the sealing ring above it to rotate, and drives the adjusting column 212 to rotate from the inside of the groove body 218 to the adjustment groove 219. Under the elastic force of the elastic member 215, the T-shaped block 213 and the adjusting column 212 are driven to move, and the adjusting column 212 moves to the inner wall of the adjustment groove 219. At this time, the correcting plates 202 move away from each other and no longer clamp the placement jig 4, and the rotating bar 302 drives the airbag 305 to rotate to its original position, and no longer squeezes and fixes the placement jig 4, so that the conveying component 105 absorbs and transfers the detected placement jig 4 and the sealing ring to the blanking component 104 for transportation.

[0059] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative; within the scope of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
