Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber plate defect detection, in particular to a carbon fiber plate detection device based on machine vision. Background Art

[0002] Carbon fiber boards are widely used in aerospace, automobile manufacturing, sports equipment and other fields due to their high strength, low density and excellent corrosion resistance. However, carbon fiber boards may produce defects such as cracks, bubbles, and fiber dislocation during the production process, which seriously affect their performance.

[0003] Some existing detection devices directly place the carbon fiber plate on the device, and then immerse it in the detection liquid, and perform detection by scanning back and forth with the camera head above. However, during the detection, when the carbon fiber plate is immersed in the detection liquid, factors such as the surface tension, fluctuations, and possible bubbles of the liquid may affect the shooting effect of the camera head. For example, the refraction of the liquid may cause the image to be deformed, blurred, etc., making the defects unclear in the image, thereby affecting the accuracy of the detection results.

[0004] A Chinese patent with authorization announcement number CN213337477U discloses an automated detection device for carbon fiber plates. The device actively displaces the carbon fiber plates and automatically sprays the detection liquid through an automated setting. After the detection is completed, the plates are dried by a drying fan, which saves manpower and improves detection efficiency.

[0005] However, there are still some problems with this patent: although the device can automatically spray the detection liquid, the detection liquid may be uneven when it is sprayed in the air and falls on the carbon fiber plate, which may affect the test results during subsequent tests. In addition, the surface of the carbon fiber plate should be cleaned before spraying the detection liquid to avoid oil stains that may affect subsequent test results. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] This is the first embodiment of the present invention, which provides a carbon fiber plate detection device based on machine vision.

[0037] Reference Figure 1 to Figure 3 and Figure 6 Specifically, it includes: a detection assembly 100, including a frame 101, an operation table 102 arranged on the end surface of the frame 101, a guide rail 103 arranged at the end of the operation table 102, and a detection component 104 movably arranged on the outer wall of the guide rail 103;

[0038] The smear cleaning assembly 200 includes a double-sided roller 201, a servo motor 202 and an insertion joint 203 arranged on the outer wall of the double-sided roller 201, a moving block 204 arranged on the outer wall of the double-sided roller 201, and a closing component 205 and a connecting head 206 arranged on the inner wall of the moving block 204.

[0039] The carbon fiber plate is fixed on the surface of the operating table 102 through a vacuum suction port on the surface of the operating table 102, and the detection component 104 moves in a zigzag shape above the carbon fiber plate, and the surface of the carbon fiber plate is scanned and detected by the industrial camera at the bottom.

[0040] The smear cleaning component 200 moves on the surface of the operating table 102. The double-sided roller 201 has two sides. One side is used to clean the dirt on the surface of the carbon fiber board, and the other side is used to evenly smear the detection liquid on the surface of the carbon fiber board, which is beneficial for the detection component 104 to detect the carbon fiber board. The double-sided roller 201 is controlled by the servo motor 202 to adjust the side of the double-sided roller 201 facing the carbon fiber board.

[0041] When the servo motor 202 controls the double-sided roller 201 to flip, the insertion joint 203 on the side of the double-sided roller 201 slides on the inner wall of the moving block 204 to open the closing component 205. At the same time, the moving block 204 slides toward the double-sided roller 201, so that the connecting head 206 is connected with the insertion joint 203. At this time, the detection liquid is input into the interior of the double-sided roller 201 through the pressure pump, so that the double-sided roller 201 can apply it to the surface of the carbon fiber plate.

[0042] In summary, when in use, the smearing and cleaning component 200 moves linearly on the surface of the operating table 102, and the servo motor 202 controls the double-sided roller 201 to face the side of the carbon fiber plate. When passing through the carbon fiber plate for the first time, the servo motor 202 rotates the double-sided roller 201 so that the side responsible for cleaning faces downward, and cleans the surface of the carbon fiber plate when passing through the carbon fiber plate, and then rotates the double-sided roller 201 to align the insertion joint 203 on the surface of the double-sided roller 201 with the closing component 205 in the moving block 204. After alignment, the closing component 205 opens, and at the same time, as the smearing and cleaning component 200 moves, the moving block 204 approaches the double-sided roller 201. At this time, the insertion joint 203 and the connecting head 206 are connected, and the detection liquid enters the insertion joint 203 through the connecting head 206, and finally flows into the double-sided roller 201. When the smearing and cleaning component 200 returns backward, the detection liquid is evenly smeared on the surface of the carbon fiber plate through the double-sided roller 201, and then the carbon fiber plate is detected by the detection component 104.

[0043] Example 2

[0044] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0045] Specifically, refer to Figure 1 to Figure 3 A drag chain 1021 is provided on the end face of the operating table 102 , a connecting pipe is provided on the inner wall of the drag chain 1021 and the connecting pipe is connected to the connecting head 206 , a road groove 1022 is also provided on the end face of the operating table 102 and a curved groove 1023 is provided at the end of the road groove 1022 .

[0046] The detection liquid is transported by a pressure pump and flows in the connecting tube. The top of the connecting tube is connected to the connector 206. As the connector 206 moves on the surface of the operating table 102, the connecting tube is protected by the drag chain 1021 to avoid bending and clogging of the pipeline.

[0047] The upper surface of the operating table 102 is symmetrically provided with grooves 1022. The difference is that a curved groove 1023 is provided at the top of the groove 1022 at the end of the moving block 204. When the moving block 204 passes through the curved groove 1023, it will approach the double-sided roller 201 along the path of the curved groove 1023.

[0048] Preferably, refer to Figure 5 The end surface of the double-sided roller 201 is provided with a cleaning surface 2011 and a coating surface 2012 , the inner wall of the coating surface 2012 is provided with a cavity 2013 and the inner wall of the cavity 2013 is provided with a flow hole 2014 , and a driving shaft 2021 is provided at the axis center of the servo motor 202 and the driving shaft 2021 passes through the double-sided roller 201 .

[0049] Among them, the double-sided roller 201 is divided into two sides, the surface of the cleaning surface 2011 is provided with a cleaning brush and a wiping cloth, the surface of the smearing surface 2012 is installed with a high-density sponge, and a cavity 2013 is opened inside to hold the detection liquid entering the inside. After the detection liquid enters the cavity 2013, it enters the high-density sponge through the flow hole 2014, and soaks the sponge without dripping. The cavity 2013 is connected to the insertion joint 203. Only when the insertion joint 203 and the connecting head 206 are connected, the detection liquid will enter the interior of the cavity 2013. At the same time, when there is no contact, the insertion joint 203 is sealed to prevent the detection liquid from overflowing or external impurities from entering the cavity 2013.

[0050] A first baffle ring 2031 is provided on the inner wall of the insertion joint 203, and an abutment rod 2032 is also provided on the inner wall of the insertion joint 203, and a first elastic member 2033 is provided on the outer wall of the abutment rod 2032. One end of the first elastic member 2033 is located on the outer wall of the first baffle ring 2031 and the other end pushes the abutment rod 2032 to make its outer wall fit the inner wall of the insertion joint 203, thereby sealing the insertion joint 203.

[0051] Among them, the surface of the first baffle ring 2031 is provided with multiple flow ports for the circulation of the detection liquid. At the same time, the first baffle ring 2031 is fixed inside the insertion joint 203, one end of the first elastic member 2033 is in contact with the first baffle ring 2031, and the other end is against the outer side of the abutment rod 2032. The elasticity of the first elastic member 2033 pushes the abutment rod 2032 toward the outer side of the insertion joint 203, so that the outer wall of the abutment rod 2032 is close to the inner wall of the insertion joint 203.

[0052] Reference Figure 5 , Figure 6 The moving block 204 is arranged on the outer wall of the double-sided roller 201, and drives the double-sided roller 201 to move on the end surface of the operating table 102 together with the servo motor 202. A slide groove 2041 is opened on the end surface of the moving block 204, and the end of the insertion joint 203 extends to the inner wall of the slide groove 2041 and slides with it.

[0053] The moving block 204 and the servo motor 202 move synchronously on the track on the surface of the operating table 102 on both sides of the double-sided roller 201 . The difference is that the moving block 204 slides in the groove 1022 with the curved groove 1023 .

[0054] The slide groove 2041 provided on the surface of the moving block 204 is a semicircular arc groove. The double-sided roller 201 rotates under the control of the servo motor 202 , and the insertion joint 203 connected on the surface slides inside the slide groove 2041 .

[0055] Reference Figure 6 , Figure 7 Preferably, a pushing plate 2042 is provided on the inner wall of the moving block 204 and the end of the pushing plate 2042 extends to the inner wall of the slide groove 2041. When the end of the inserted joint 203 slides along the inner wall of the slide groove 2041, it contacts and squeezes the pushing plate 2042. A sleeve 2043 is movably provided on the end of the pushing plate 2042 and a movable groove 2044 is provided on the outer wall of the sleeve 2043. A limiting rod 2045 is fixed on the inner wall of the moving block 204 and the end of the limiting rod 2045 extends to the inner wall of the movable groove 2044 and slides with it. When the pushing plate 2042 is squeezed, the sleeve 2043 is driven to move on the inner wall of the moving block 204. The end of the limiting rod 2045 slides along the inner wall of the movable groove 2044 and drives the sleeve 2043 to rotate. A second elastic member 2046 is provided on the end of the sleeve 2043 and the second elastic member 2046 is deformed.

[0056] Among them, the inner wall of the moving block 204 is provided with an accommodating cavity, and a limiting rod 2045 is fixedly installed inside the accommodating cavity. The limiting rod 2045 is on the outer side of the sleeve 2043 and slides with the movable groove 2044 on the surface of the sleeve 2043. The sleeve 2043 is restricted inside the moving block 204 and can only rotate up and down but cannot translate left and right. The connecting column under the pushing plate 2042 moves inside the sleeve 2043, and at the same time, the pushing plate 2042 extends out in the sliding groove 2041. When the inserted joint 203 rotates downward to the bottom inside the sliding groove 2041, it first touches the pushing plate 2042, causing it to move downward in the sliding groove 2041 and squeeze the sleeve 2043 below. When the movable groove 2044 on the surface of the sleeve 2043 moves downward, it is affected by the limiting rod 2045 on one side. When the sleeve 2043 descends, it rotates and squeezes the second elastic member 2046 below to deform it.

[0057] In summary, when in use, the smear cleaning component 200 moves on the upper surface of the operating table 102, and the servo motor 202 on one side of the double-sided roller 201 drives the double-sided roller 201 to flip. When passing for the first time, the servo motor 202 is not driven. At this time, the cleaning surface 2011 of the double-sided roller 201 faces downward, and the insertion joint 203 on the side of the double-sided roller 201 is located above the slide groove 2041 on the surface of the moving block 204. After the cleaning surface 2011 passes the carbon fiber plate below and cleans the carbon fiber plate, the servo motor 202 flips the double-sided roller 201 through the drive shaft 2021, and the insertion joint 203 flips inside the slide groove 2041 along the inner wall of the slide groove 2041.

[0058] When flipped to the bottom, it contacts the push plate 2042 extending out of the slide groove 2041, and then the joint 203 is inserted to squeeze the push plate 2042 to move it downward. When the push plate 2042 moves downward, the sleeve 2043 below moves downward together. At the same time, the sleeve 2043 is restricted by the limiting rod 2045 on one side, and the sleeve 2043 rotates and squeezes the second elastic member 2046 below when moving downward to deform it.

[0059] Example 3

The surface array of the swivel 2058 is provided with a hollow plate 2059. One end of the convex column 2057 on the surface of the closing plate 2054 extends out from the hollow plate 2059, and the other end of the convex column 2057 extends into the connecting groove 2052 on the surface of the covering plate 2051.

[0065] The connecting rod 20510 on the surface of the swivel 2058 extends from the opening 2053 on the surface of the covering plate 2051 to the accommodating cavity inside the moving block 204. The other end of the connecting rod 20510 is hinged with a rotating rod 20511 through a universal joint. The rotating rod 20511 is connected to the sleeve 2043 to form a whole. Therefore, when the sleeve 2043 rotates, the connecting rod 20510 is driven to rotate through the rotating rod 20511.

[0066] The connecting rod 20510 and the swivel 2058 are an integral whole. The rotation of the connecting rod 20510 drives the swivel 2058 to rotate inside the covering plate 2051. When the swivel 2058 rotates, the boss 2057 slides inside the hollow plate 2059 on the surface, and the boss 2057 slides inside the connecting groove 2052. At this time, the outer walls of the closing plate 2054 move in contact with each other, and the convex plate 2055 on the side of the closing plate 2054 slides on the inner wall of the groove 2056 on the side of the adjacent closing plate 2054.

[0069] In summary, when in use, after the double-sided roller 201 passes through the carbon fiber plate, the servo motor 202 drives the double-sided roller 201 to flip. When the double-sided roller 201 flips, the side insertion joint 203 slides inside the slide groove 2041 on the surface of the moving block 204 and squeezes the push plate 2042 to move it downward. Through the downward movement of the push plate 2042, the sleeve 2043 moves downward inside the moving block 204, and at the same time, it is affected by the limiting rod 2045 on one side and rotates when moving downward. At this time, the sleeve 2043 rotates and drives the outer side of the rotating rod 20511 connected to it to rotate together. Since the rotating rod 20511 is hinged to the connecting rod 20510 on the surface of the rotating ring 2058, the rotating ring 2058 rotates at this time to open the closing plate 2054 of the internal array of the covering plate 2051, exposing the rear connecting head 206.

[0070] At this time, the insertion joint 203 on the surface of the double-sided roller 201 is opposite to the connecting head 206 on the rear side of the closing component 205, but they are not in contact. As the smear cleaning component 200 continues to move on the surface of the operating table 102, when the moving block 204 moves in the road groove 1022 and enters the curved groove 1023, the moving block 204 moves toward the direction of the double-sided roller 201. At this time, the closing component 205 and the connecting head 206 approach the insertion joint 203, and finally the insertion joint 203 enters the connecting port 2061 at the front end of the connecting head 206 through the opening of the closing plate 2054. At this time, the abutment rod 2032 and the plug-in rod 2063 conflict with each other and move backward together. At this time, the detection liquid inside the connecting tube can enter the cavity 2013 of the double-sided roller 201 through the insertion joint 203.

[0071] After that, the smear cleaning component 200 moves backward and withdraws from the curved groove 1023, and the insertion joint 203 is separated from the connecting head 206 and sealed up again. At the same time, the insertion joint 203 is also pulled out from the opened mouth of the closing plate 2054. However, at this time, since the insertion joint 203 is still located at the bottom end of the slide groove 2041 and squeezes the push plate 2042, the closing plate 2054 cannot be closed. When the smear cleaning component 200 moves backward and smears the detection liquid on the surface of the carbon fiber plate through the smearing surface 2012, the servo motor 202 drives the double-sided roller 201 to flip. At this time, the push plate 2042 is reset, and the closing plate 2054 is closed again, which has a double sealing effect on the connecting head 206 to prevent the detection liquid from leaking out, and finally the carbon fiber plate is inspected through the detection component 104.
