Description

Technical Field

[0001] The present 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 plates, with their high strength, low density, and excellent corrosion resistance, are widely used in many fields such as aerospace, automotive manufacturing, and sports equipment. However, during the production process of carbon fiber plates, defects such as cracks, bubbles, and fiber misalignment may occur, 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 the camera head above scans back and forth for detection. However, when detecting, when the carbon fiber plate is immersed in the detection liquid, factors such as the surface tension, fluctuation of the liquid, and possible bubbles may affect the shooting effect of the camera head. For example, the refraction of the liquid may cause phenomena such as image distortion and blurring, making the defects not clearly presented in the image, thus affecting the accuracy of the detection results.

[0004] The Chinese patent with the authorization announcement number CN213337477U discloses a carbon fiber plate automatic detection device. This device adopts an automatic setting, actively displaces the carbon fiber plate, and automatically sprays the detection liquid. After the detection is completed, it is dried by a drying fan, saving manpower and improving the 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 sprayed in the air and falls on the carbon fiber plate, which may affect the detection results during subsequent detection. And before spraying the detection liquid, the surface of the carbon fiber plate should be cleaned to avoid situations such as oil stains that may affect the subsequent detection results.

Detailed implementation manners

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0033] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Persons skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, as used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in an embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other.

[0035] Embodiment 1

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

[0037] Referring to Figures 1 to 3 and Figure 6 , specifically, it includes: a detection component 100, which includes a frame 101, an operating table 102 provided on the end face of the frame 101, a guide rail 103 provided at the end of the operating table 102, and a detection component 104 movably arranged on the outer wall of the guide rail 103;

[0038] A smearing and cleaning component 200, which includes a double-sided roller 201, a servo motor 202 and an insertion joint 203 provided on the outer wall of the double-sided roller 201, a moving block 204 provided on the outer wall of the double-sided roller 201, a closing component 205 provided inside the moving block 204, and a connecting head 206.

[0039] Among them, 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. 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 an industrial camera at the bottom.

[0040] The smearing and 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 plate, and the other side is used to evenly smear the detection liquid on the surface of the carbon fiber plate, which is beneficial for the detection component 104 to detect the carbon fiber plate. 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 plate.

[0041] When the servo motor 202 controls the flipping of the double-sided roller 201, the insertion joint 203 on the side of the double-sided roller 201 slides on the inner wall of the moving block 204, opening the closing component 205. At the same time, the moving block 204 slides towards the double-sided roller 201, causing the connecting head 206 to communicate with the insertion joint 203. At this time, the detection liquid is input into the interior of the double-sided roller 201 through a pressure pump, facilitating the application of the detection liquid to the surface of the carbon fiber board by the double-sided roller 201.

[0042] In summary, during use, the coating and cleaning assembly 200 moves linearly on the surface of the operating table 102. The servo motor 202 controls the side of the double-sided roller 201 facing the carbon fiber board. When passing over the carbon fiber board for the first time, the servo motor 202 rotates the double-sided roller 201 so that the side responsible for cleaning faces downwards, cleaning the surface of the carbon fiber board when passing over it. Then, the double-sided roller 201 is rotated so that the insertion joint 203 on the surface of the double-sided roller 201 aligns with the closing component 205 inside the moving block 204. After alignment, the closing component 205 opens. At the same time, as the coating and cleaning assembly 200 moves, the moving block 204 approaches the double-sided roller 201. At this time, the insertion joint 203 communicates with the connecting head 206, 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 coating and cleaning assembly 200 moves backward, the detection liquid is evenly applied to the surface of the carbon fiber board by the double-sided roller 201, and then the carbon fiber board is detected by the detection component 104.

[0043] Embodiment 2

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

[0045] Specifically, referring to Figures 1 to 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 communicates with the connecting head 206. A path 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 path groove 1022.

[0046] Among them, the detection liquid is transported by a pressure pump and flows in the connecting pipe. The top end of the connecting pipe communicates with the connecting head 206. And as the connecting head 206 moves on the surface of the operating table 102, the drag chain 1021 protects the connecting pipe to prevent bending and resulting in pipeline blockage.

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

[0048] Preferably, referring toFigure 5 On the end face of the double-sided roller 201, there are a cleaning surface 2011 and an application surface 2012. Inside the application surface 2012, there is a cavity 2013, and flow holes 2014 are opened on the inner wall of the cavity 2013. At the center of the servo motor 202, there is a drive shaft 2021, and the drive shaft 2021 penetrates through the double-sided roller 201.

[0049] Among them, the double-sided roller 201 is divided into two sides. On the surface of the cleaning surface 2011, there are cleaning brushes and wiping cloths. On the surface of the application surface 2012, a high-density sponge is installed. Inside, there is a cavity 2013 for containing the detection liquid that enters. After the detection liquid enters the cavity 2013, it enters the high-density sponge through the flow holes 2014, soaking the sponge without dripping. The cavity 2013 is connected to the insertion joint 203. Only when the insertion joint 203 and the connection joint 206 are connected, the detection liquid will enter the inside of the cavity 2013. At the same time, when not in contact, the insertion joint 203 is sealed to prevent the detection liquid from overflowing or external impurities from entering the cavity 2013.

[0050] On the inner wall of the insertion joint 203, there is a first retaining ring 2031. On the inner wall of the insertion joint 203, there is also a contact rod 2032, and on the outer wall of the contact rod 2032, there is a first elastic member 2033. One end of the first elastic member 2033 is located on the outer wall of the first retaining ring 2031, and the other end pushes the contact rod 2032 so that its outer wall fits against the inner wall of the insertion joint 203 to seal the insertion joint 203.

[0051] Among them, a plurality of flow ports are opened on the surface of the first retaining ring 2031 for the flow of the detection liquid. At the same time, the first retaining ring 2031 is fixed inside the insertion joint 203. One end of the first elastic member 2033 contacts the first retaining ring 2031, and the other end abuts against the outside of the contact rod 2032. Through the elasticity of the first elastic member 2033, the contact rod 2032 is pushed towards the outside of the insertion joint 203, so that the outer wall of the contact rod 2032 is close to the inner wall of the insertion joint 203.

[0052] Refer to Figure 5 、 Figure 6 , the moving block 204 is arranged on the outer wall of the double-sided roller 201, and together with the servo motor 202, drives the double-sided roller 201 to move on the end face of the operation table 102. On the end face of the moving block 204, there is a chute 2041, and the end of the insertion joint 203 extends into the inner wall of the chute 2041 and is slidably matched with it.

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

[0054] The sliding groove 2041 formed on the surface of the moving block 204 is a semi-circular arc groove. The double-sided roller 201 rotates under the control of the servo motor 202, and the insertion joint 203 communicated with the surface slides inside the sliding groove 2041.

[0055] Referring to Figure 6 、 Figure 7 Preferably, a push plate 2042 is provided on the inner wall of the moving block 204, and the end of the push plate 2042 extends to the inner wall of the sliding groove 2041. When the end of the insertion joint 203 slides along the inner wall of the sliding groove 2041, it touches and presses the push plate 2042. A sleeve 2043 is movably provided at the end of the push plate 2042, and a movable groove 2044 is formed 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 is slidably engaged therewith. When the push plate 2042 is pressed, it drives the sleeve 2043 to move inside 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 at the end of the sleeve 2043, and the second elastic member 2046 deforms.

[0056] Among them, a receiving cavity is formed on the inner wall of the moving block 204, and the limiting rod 2045 is fixedly installed inside the receiving cavity. The limiting rod 2045 is on the outside of the sleeve 2043 and is slidably engaged 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 and cannot translate left and right. The connecting column below the push plate 2042 moves inside the sleeve 2043, and at the same time, the push plate 2042 extends out of the sliding groove 2041. When the insertion joint 203 rotates downward to the bottom inside the sliding groove 2041, it first touches the push plate 2042, causing it to move downward in the sliding groove 2041 and simultaneously squeezing the lower sleeve 2043. 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 simultaneously squeezes the lower second elastic member 2046, causing it to deform.

[0057] In summary, during use, the coating cleaning assembly 200 moves on the upper surface of the operating table 102, and the double-sided roller 201 is driven to flip by the servo motor 202 on one side of the double-sided roller 201. When passing by for the first time, the servo motor 202 does not drive at this time. At this time, the cleaning surface 2011 of the double-sided roller 201 faces downward, and at the same time, the insertion joint 203 on the side of the double-sided roller 201 is located above the sliding groove 2041 on the surface of the moving block 204. After the cleaning surface 2011 passes the lower carbon fiber board and cleans the carbon fiber board, at this time, the servo motor 202 causes the double-sided roller 201 to flip through the drive shaft 2021, and the insertion joint 203 flips along the inner wall of the sliding groove 2041 inside the sliding groove 2041.

[0058] When it is flipped to the bottom, it touches the push plate 2042 protruding from the chute 2041. Then, the insertion joint 203 is inserted to squeeze the push plate 2042, causing it to move downward. When the push plate 2042 moves downward, the lower sleeve 2043 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 lower second elastic member 2046 downward when moving downward, causing it to deform.

[0059] Embodiment 3

[0060] This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0061] Specifically, referring to Figure 7 、 Figure 8 , the closing member 205 includes a covering plate 2051. A connecting groove 2052 is formed on the inner wall of the covering plate 2051. An opening 2053 is formed through the outer wall of the covering plate 2051. A plurality of closing plates 2054 are arranged in an array on the inner wall of the covering plate 2051. A convex plate 2055 and a groove 2056 are arranged on the outer wall of the closing plate 2054. The outer wall of the convex plate 2055 extends into the groove 2056 on the outer wall of the adjacent closing plate 2054 and is slidably matched with it.

[0062] Among them, the closing member 205 is communicated with the chute 2041 and is located at the bottom of the chute 2041. The covering plate 2051 is fixed inside the moving block 204, and the lower part of the covering plate 2051 is communicated with the accommodation cavity inside the moving block 204. A plurality of closing plates 2054 are arranged in an array inside the covering plate 2051. A convex plate 2055 and a groove 2056 are respectively arranged on the side of the closing plate 2054. The convex plate 2055 on the side of the closing plate 2054 extends into the groove 2056 on the side of the adjacent closing plate 2054 to enhance its sealing performance.

[0063] Preferably, a rotating ring 2058 is further arranged on the inner wall of the covering plate 2051. A hollow plate 2059 is connected to the outer wall of the rotating ring 2058. A convex column 2057 is arranged on the outer wall of the closing plate 2054, and the end of the convex column 2057 extends to the inner wall of the hollow plate 2059. The other end of the convex column 2057 extends to the inner wall of the connecting groove 2052 and is slidably matched with it. A connecting rod 20510 is further connected to the outside of the rotating ring 2058, and the end of the connecting rod 20510 extends to the outer wall of the covering plate 2051 and slides on the inner wall of the opening 2053. The end of the connecting rod 20510 is movably connected to a rotating rod 20511, and the other end of the rotating rod 20511 is connected to the sleeve 2043.

[0064] Among them, the swivel ring 2058 is movably arranged inside the cladding plate 2051, attached to the outer surface of the closing plate 2054, clamping the closing plate 2054 inside the cladding plate 2051. The surface of the swivel ring 2058 is arrayed with hollow plates 2059. One end of the convex post 2057 on the surface of the closing plate 2054 extends out from within the hollow plate 2059, and the other end of the convex post 2057 extends into the connecting groove 2052 on the surface of the cladding plate 2051.

[0065] The connecting rod 20510 on the surface of the swivel ring 2058 extends out from the opening 2053 on the surface of the cladding plate 2051 into 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 an integral body. Therefore, when the sleeve 2043 rotates, the connecting rod 20510 is driven to rotate by the rotating rod 20511.

[0066] The connecting rod 20510 and the swivel ring 2058 are an integral body. The rotation of the connecting rod 20510 drives the swivel ring 2058 to rotate inside the cladding plate 2051. When the swivel ring 2058 rotates, the convex post 2057 slides inside the hollow plate 2059 on the surface, and at the same time, the convex post 2057 slides inside the connecting groove 2052. At this time, the outer walls of the closing plate 2054 fit and move with each other. 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. The top position of the closing plate 2054 separates, and the closing component 205 opens.

[0067] Preferably, referring to Figure 9 , the end of the connector 206 is provided with a connection port 2061, and the inner wall of the connector 206 is provided with a second retaining ring 2062. The inner wall of the connector 206 is also provided with a plug rod 2063, and the outer wall of the plug rod 2063 is provided with a third elastic member 2064.

[0068] Among them, the connector 206 is connected to the outside of the cladding plate 2051. After the closing plate 2054 is opened, the connection port 2061 and the plug rod 2063 inside the connector 206 are exposed. The second retaining ring 2062 inside the connector 206 is the same as the first retaining ring 2031, with a flow port opened on the surface. At the same time, the plug rod 2063 is pushed to the outside of the connector 206 through the internal third elastic member 2064 to seal the connector 206.

[0069] In summary, during use, after the double-sided roller 201 passes over the carbon fiber board, the servo motor 202 drives the double-sided roller 201 to flip. When the double-sided roller 201 flips, the insertion joint 203 on the side slides inside the chute 2041 on the surface of the moving block 204 and presses against the push plate 2042 to move it downward. Due to the downward movement of the push plate 2042, the sleeve 2043 moves downward inside the moving block 204. At the same time, affected by the limiting rod 2045 on one side, it rotates when moving downward. At this time, the sleeve 2043 rotates to drive the rotating rod 20511 connected to its outside to rotate together. Since the rotating rod 20511 is hinged to the connecting rod 20510 on the surface of the rotating ring 2058, at this time, the rotating ring 2058 rotates to open the closing plates 2054 arranged in an array inside the covering plate 2051, exposing the connecting head 206 at the back.

[0070] At this time, the insertion joint 203 on the surface of the double-sided roller 201 is opposite to the connecting head 206 at the rear of the closing component 205 in position but does not touch. As the coating and cleaning assembly 200 continues to move on the surface of the operating table 102, when the moving block 204 moves into the curved groove 1023 inside the road groove 1022, the moving block 204 moves toward the double-sided roller 201. At this time, the closing component 205 and the connecting head 206 move closer to the insertion joint 203. Finally, the insertion joint 203 enters the connecting port 2061 at the front end of the connecting head 206 through the opening formed by the opening of the closing plate 2054. At this time, the abutting rod 2032 and the inserting rod 2063 abut against each other and move backward together. At this time, the detection liquid inside the connecting pipe can enter the cavity 2013 inside the double-sided roller 201 through the insertion joint 203.

[0071] After that, when the coating and cleaning assembly 200 moves backward and exits from the curved groove 1023, the insertion joint 203 separates from the connecting head 206, and each is hermetically sealed again. At the same time, the insertion joint 203 also withdraws from the opening formed by the opening of the closing plate 2054. However, at this time, since the insertion joint 203 is still at the bottom end of the chute 2041 pressing against the push plate 2042, the closing plate 2054 cannot be closed. When the coating and cleaning assembly 200 moves backward and after applying the detection liquid to the surface of the carbon fiber board through the coating surface 2012, the servo motor 202 drives the double-sided roller 201 to flip. At this time, the push plate 2042 resets, and the closing plate 2054 closes again, playing a dual hermetic role for the connecting head 206 to prevent the detection liquid from leaking. Finally, the carbon fiber board is detected by the detection component 104.
