Description

Technical Field

[0001] This invention relates to the field of diamond composite sheet testing technology, specifically to a defect detection device for diamond composite sheet production and processing. Background Technology

[0002] Diamond composite sheets, a type of superhard material formed by combining polycrystalline diamond layers with a cemented carbide matrix, possess high hardness, high wear resistance, and good impact resistance, and are widely used in oil drilling, mining, and geological exploration. Since the performance and service life of diamond composite sheets are closely related to their production quality, it is usually necessary to inspect their surface condition, edge integrity, and processing quality after production to prevent products with defects such as cracks, chipped edges, or missing corners from entering subsequent use.

[0003] Existing methods for inspecting diamond composite sheets typically employ ultrasonic testing to assess internal sintering defects. However, these testing devices are complex and have long testing cycles, often requiring sampling in actual production, which fails to meet the need for rapid and comprehensive inspection of every single diamond composite sheet. For surface and edge defects, manual visual inspection or industrial vision inspection is commonly used. While advancements in vision inspection technology have replaced some manual processes and improved accuracy, existing vision inspection equipment still suffers from insufficient inspection efficiency.

[0004] Specifically, diamond composite sheets are small in size and require comprehensive observation of their front, back, and edge areas. Therefore, during the inspection process, it is usually necessary to feed the composite sheets one by one, adjust their positions, center and position them, and flip them over to ensure that different inspection surfaces are in the optimal inspection position of the camera device. The above process involves a large number of auxiliary actions, while the actual image acquisition time is short, which limits the overall working cycle of the inspection equipment and makes it difficult to meet the needs of fast and efficient inspection in the mass production of diamond composite sheets.

[0015] Compared with the prior art, the beneficial effects of the present invention are: During inspection, this invention drives the rotating limiting plate on the side to be tested to rotate vertically upwards to avoid the workpiece edge, providing a completely unobstructed optical inspection space for the vision camera and solving the problem of missed detection caused by boundary obstruction in traditional clamping. Simultaneously, by using air path switching control to apply negative pressure to the workpiece on the non-inspection side, combined with flexible adsorption plates and adsorption pores, it ensures that the workpiece maintains extremely high positioning stability even with unobstructed edges. Furthermore, the drive motor can drive the mounting support circular base and the entire square inspection carrier to reciprocate or rotate to change the inspection tilt angle, causing hidden defects such as microcracks and chipping on the diamond composite sheet surface to produce light and dark contrast under changes in the external lighting angle, enhancing the defect detection capability of the vision system. In addition, with the light guide layer at the interlayer, external light can be reflected a second time to the side of the workpiece, achieving passive precision edge illumination and reducing blind spots in inspection. The square detection bearing plate of this invention adopts a lightweight design that can be independently separated from the mounting support round base. Both are low-cost, passively cooperating mechanical structures, allowing for batch configuration and use by enterprises. When loading workpieces offline, the operator can quickly and automatically center the workpiece by linking the connecting rod with the symmetrical centering blocks in the centering groove. This eliminates the need for tedious manual alignment, achieving a stable and normal posture and enabling rapid loading. During docking, the mounting frame is quickly inserted into the placement mounting slot. Its connecting clip frame and insertion head are quickly locked together by the first wedge block and the first return spring, while the sealing tube completes the rapid docking of the air circuit. Subsequently, by tightening the threaded clamping rod, the inclined surface of the second wedge block strongly presses and locks the limiting insertion rod axially, ensuring airtightness during positive and negative pressure switching while making the loading, unloading, and disassembly of the entire plate extremely convenient. Finally, the system is controlled by a four-way valve, which can drive the upper adsorption vents to spray positive pressure airflow to perform synchronous pneumatic cleaning while the lower side is under negative pressure adsorption detection. This quickly blows away the wear debris and oil stains attached to the surface. Combined with the overall flipping mechanism, it realizes rapid double-sided assembly line-style rotation detection, reducing the limitations on the working cycle caused by auxiliary actions such as position adjustment and flipping in traditional detection.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 The present invention provides a technical solution: a defect detection device for diamond composite sheet production and processing, including a detection device frame 1, a drive motor 2 fixedly installed on the upper side of the detection device frame 1, a mounting support round seat 3 fixedly installed on the output shaft of the drive motor 2, a square detection bearing plate 4 installed on the mounting support round seat 3, composite sheet placement slots 5 arrayed on the square detection bearing plate 4, and flip-limiting plates 6 rotatably installed on both the upper and lower sides of the square detection bearing plate 4, the position of the flip-limiting plates 6 being opposite to the position of the composite sheet placement slots 5, and positioning arc blocks 7 movably arranged in an array inside the square detection bearing plate 4, the position of the positioning arc blocks 7 being opposite to the position of the composite sheet placement slots 5; The limiting plate opening and closing mechanism 8 includes a flexible adsorption plate 804, a gear 805, and a rack 807. The flexible adsorption plate 804 is fixedly installed in an array on the flipping limiting plate 6. The position of the flexible adsorption plate 804 is opposite to the position of the composite plate placement groove 5. The gear 805 is fixedly installed on one lower end of the flipping limiting plate 6. The racks 807 are movably arranged on both the front and rear sides of the square detection bearing plate 4. A set of racks 807 meshes with the gears 805. The direction of movement of the racks 807 is parallel to the axis of the drive motor 2. The pneumatic connection mechanism 9 includes an inner air groove 902, a gas connection pipe 904, and an air pump 908. The flip-limit plate 6 is provided with an inner air groove 902. Two sets of gas connection pipes 904 are fixedly installed on the square detection bearing plate 4. The gas connection pipes 904 are connected to the inner air grooves 902. An air pump 908 is fixedly installed on the mounting support round seat 3. The air pump 908 is connected to the gas connection pipes 904. A composite sheet centering mechanism 10 is installed inside the square detection carrier plate 4, and an installation frame 11 is fixedly installed on one side of the square detection carrier plate 4. This equipment allows the square detection carrier plate 4 to be easily separated from the mounting support round base 3, enabling it to independently load composite sheets. Furthermore, the square detection carrier plate 4 features passively cooperating mechanical structures, resulting in low cost and batch use. This allows for rapid batch testing of composite sheets. The square detection carrier plate 4 itself has the ability to normally clamp composite sheets through the flip-limiting plate 6, and the composite sheet centering mechanism 10 and positioning arc block 7 provide centering capabilities for the loaded composite sheets. This eliminates the need for alignment when loading composite sheets into the composite sheet placement slot 5. Composite sheets with a diameter smaller than the slot 5 can also be placed in the composite sheet placement slot 5, enabling rapid loading and further testing of the composite sheets. The composite sheet already has a stable posture. This device uses a pneumatic connection mechanism 9 for negative pressure clamping. This is based on the condition that the composite sheet is in a stable state before being clamped by negative pressure. The advantage of negative pressure clamping over edge clamping is that the edge will not be blocked. After rotation, the clamping mechanism will not obstruct the detection head, allowing for more complete detection adjustment. Through the switching of negative pressure on both sides and the opening and closing of the flip limit plate 6, the composite sheet not only has the ability to automatically flip for detection, but also the ability to detect tilt angles. This allows the composite sheet to change its tilt angle, so that surface defects can be more clearly observed through changes in surface light during detection. In summary, this device has significant improvements over existing detection methods in terms of composite sheet replacement speed, degree of automation, and functionality during detection.

[0020] Furthermore, the limiting plate opening and closing mechanism 8 also includes a limiting plate mounting base 801, a limiting plate rotating shaft 802, a torsion spring 803, and a sliding guide frame 806. The limiting plate mounting bases 801 are fixedly mounted on both the upper and lower sides of the square detection bearing plate 4. The limiting plate rotating shaft 802 is fixedly mounted on one end of the flipping limiting plate 6. A torsion spring 803 is provided on the limiting plate rotating shaft 802. The limiting plate rotating shaft 802 is rotatably mounted on the limiting plate mounting base 801. One end of the torsion spring 803 is fixedly mounted inside the limiting plate mounting base 801, and the other end is fixedly mounted on the limiting plate rotating shaft 802. Sliding guide frames 806 are fixedly mounted on both the front and rear sides of the square detection bearing plate 4. A rack 807 is slidably mounted inside the sliding guide frame 806. This structure allows the flipping limit plates 6 on the same side to open synchronously and remain normally closed under the action of the torsion spring 803, so that the composite plate placed in the composite plate placement slot 5 can be clamped. The key feature is that the flipping limit plates 6 on the same side are opened and closed by the corresponding rack 807, and are not related to the state of the flipping limit plates 6 on the other side. In this way, during the detection process, the upper flipping limit plate 6 can be opened to make room for detection, while the lower flipping limit plate 6 can be closed to support the composite plate. When flipping, both sides can be closed at the same time to stabilize the composite plate and flip it over, realizing flipping detection without side clamping. Furthermore, the limiting plate opening and closing mechanism 8 also includes a guide rope ring 808, a connecting rope 809, a limiting slide groove 810, a limiting slider 811, a connecting frame 812, a limiting frame 813, a connecting block 814, an insertion head 815, a movable groove 816, a first wedge block 817, a limiting hole 818, a limiting rod 819, and a first reset spring 820. Four sets of guide rope rings 808 are fixedly installed in an array on one side of the square detection bearing plate 4. The four sets of guide rope rings 808 are symmetrically distributed on both sides of the mounting frame 11. A connecting rope 809 is movably inserted into the guide rope ring 808. One end of the connecting rope 809 is fixedly installed on the rack 807. Limiting slide grooves 810 are opened on both sides of the mounting frame 11. Limiting sliders 811 are slidably installed in the limiting slide grooves 810. A connecting frame 812 is fixedly installed on the limiting slider 811. The other end of the connecting rope 809 is fixedly installed in the connecting frame 812. Two sets of limiting frames 813 are fixedly installed on the mounting support round seat 3. A connecting long block 814 is movably inserted in the limiting frame 813. An insertion head 815 is fixedly installed at the end of the connecting long block 814. Movable grooves 816 are opened on the upper and lower sides of the insertion head 815. A first wedge block 817 is movably inserted in each of the movable grooves 816. A limiting hole 818 is opened on the first wedge block 817. A limiting rod 819 is fixedly installed in each of the movable grooves 816. The limiting rod 819 is inserted in the limiting hole 818. A first return spring 820 is sleeved on the limiting rod 819. One end of the first return spring 820 abuts against the inner side of the movable groove 816 and the other end abuts against the first wedge block 817. The insertion head 815 is inserted in the connecting frame 812. This structure is the connection structure of the rack 807. When loading the square detection carrier plate 4, the connecting long block 814 and the connecting rope 809 are connected by inserting the insertion head 815 into the connecting card frame 812 and engaging the first wedge block 817 in the groove of the connecting card frame 812. This allows the connection of the connecting rope 809 and the connecting long block 814 to be completed directly when installing the square detection carrier plate 4. Disassembly is also relatively convenient. The connecting long block 814 rotates with the square detection carrier plate 4. The rotation of the mounting support round seat 3 will not affect the connection. The movement of the two sets of connecting long blocks 814 is also independent, which provides conditions for the independent control of the subsequent flip limit plate 6. Furthermore, the limiting plate opening and closing mechanism 8 also includes a first limiting arc frame 821, a limiting T-shaped rod 822, and a second limiting arc frame 823. The first limiting arc frame 821 is fixedly installed on the drive motor 2, and the limiting T-shaped rod 822 is fixedly installed at one end of the connecting long block 814. The limiting T-shaped rod 822 is slidably installed inside the first limiting arc frame 821. The second limiting arc frame 823 is provided on the first limiting arc frame 821. The shape of the second limiting arc frame 823 is adapted to the shape of the first limiting arc frame 821. A telescopic motor 824 is fixedly installed on the detection equipment frame 1, and the output shaft of the telescopic motor 824 is fixedly installed on the second limiting arc frame 823. This structure is a drive structure after the connecting rope 809 and the connecting long block 814 are connected. Its characteristic is that it can adapt to the rotation of the connecting long block 814. After the square detection bearing plate 4 rotates into position, the output shaft of the telescopic motor 824 retracts, the second limiting arc frame 823 and the first limiting arc frame 821 are misaligned, and a set of connecting long blocks 814 are stretched, thereby stretching the connecting rope 809, driving the rack 807 to move, and through meshing, driving the gear 805 to rotate, thus changing the flipping limiting piece 6 from horizontal to vertical. Since the limiting T-shaped round rod 822 can be positioned within the second limiting arc frame 82... 3. Sliding within, so in the stretched state, the square detection bearing plate 4 can change its tilt angle within a certain range under the drive of the drive motor 2. After flipping, the limiting T-shaped round rod 822 on the other set of connecting long blocks 814 moves into the second limiting arc frame 823. So when the telescopic motor 824 is stretched, it will only pull the upper flipping limiting piece 6 to open. The rotation axis of the flipping limiting piece 6 is perpendicular to the rotation axis of the drive motor 2. So even if the square detection bearing plate 4 changes its tilt angle after the flipping limiting piece 6 is opened, it will not affect the normal shooting of the detection head. Furthermore, the pneumatic connection mechanism 9 also includes adsorption vents 901, a first connecting groove 903, a sealing tube 905, a second connecting groove 906, an airtight connector 907, a four-way valve 909, and a placement and installation groove 910. Adsorption vents 901 are arrayed on the flexible adsorption sheet 804, and the adsorption vents 901 communicate with the inner groove 902. A first connecting groove 903 is provided at the pivot of the flip-limiting plate 6, and the first connecting groove 903 communicates with the inner groove 902. Sealing tubes 905 are fixedly installed in an array on the gas connection pipe 904. The sealing tube 905 is inserted into the first connecting air groove 903 and fits tightly with the first connecting air groove 903. Two sets of second connecting air grooves 906 are provided on the mounting frame 11. The second connecting air grooves 906 are connected to the gas connecting pipe 904. A placement mounting groove 910 is provided at the center of the mounting support round seat 3. The mounting frame 11 is inserted into the placement mounting groove 910. Two sets of airtight connectors 907 are fixedly installed in the placement mounting groove 910. The airtight connectors 907 are inserted into the second connecting air grooves 906 and fit tightly with the second connecting air grooves 906. This structure allows the gas connection pipe 904 to automatically connect to the air pump 908 after the square detection carrier plate 4 is installed, which is convenient for installation. In addition, the air inlet and outlet of the air pump 908 are on the same side and are connected to the airtight connector 907 respectively. Each set of airtight connectors 907 is connected to a set of gas connection pipes 904. Therefore, the air pump 908 can achieve negative pressure adsorption of the composite sheet by the flipping limiting plate 6 on one side through air inlet and outlet, while the composite sheet can be blown by air outlet on the other side. Furthermore, the pneumatic connection mechanism 9 also includes a four-way valve 909 and a placement and installation groove 910. The four-way valve 909 is installed on the air pump 908. The four-way valve 909 is installed in the mounting support round seat 3. All airtight connectors 907 are connected to the four-way valve 909. The other two sets of air ports of the four-way valve 909 are connected to the outside. Controlled by the four-way valve 909, the negative pressure and exhaust of the flip-limit plate 6 on different sides can be controlled independently. For example, under the control of the four-way valve 909, the air inlet of the air pump 908 is connected to the lower gas connection pipe 904, and the air outlet is connected to the outside, so that a negative pressure is formed in the inner air groove 902. The composite plate is adsorbed by the deformation of the flexible adsorption plate 804, so that it will not shift when performing tilt angle detection. While the composite plate is adsorbed by the lower flip-limit plate 6, the air circuit connection between the air pump 908 and the lower flip-limit plate 6 is cut off by the four-way valve 909, so that the lower flip-limit plate 6 can maintain a negative pressure, so that the air pump 908 is connected to the upper gas connection pipe 904, and air is introduced from the outside and delivered to the upper gas connection pipe 904. It is then sprayed out through the upper adsorption air hole 901, thereby completing the pneumatic cleaning of the composite plate interface to be tested. The control of the four-way valve 909 is a mature existing technology, and the specific working principle will not be described in detail here. Furthermore, the pneumatic connection mechanism 9 also includes a receiving and mounting groove 911, a limiting guide hole 912, a screw sleeve 913, a threaded clamping rod 914, a second wedge block 915, and a limiting insert rod 916. The receiving and mounting groove 911 is provided in the mounting support round seat 3, and the receiving and mounting groove 911 is connected to the placement mounting groove 910. Two sets of limiting guide holes 912 are provided on the receiving and mounting groove 911. A screw sleeve 913 is fixedly installed on the upper side of the mounting support round seat 3. The screw sleeve 913 is threadedly connected to the threaded clamping rod 914. A second wedge block 915 is provided in the receiving and mounting groove 911. The threaded clamping rod 914 is rotatably installed on the second wedge block 915. Two sets of limiting insert rods 916 are fixedly installed on the upper side of the second wedge block 915. The limiting insert rods 916 are inserted into the limiting guide holes 912. This structure is a limiting structure for the mounting frame 11. The second wedge block 915 is inserted into the mounting frame 11, so that the square detection bearing plate 4 and the mounting support round seat 3 are connected. One side of the second wedge block 915 is a slope, so that when the second wedge block 915 is lowered, the mounting frame 11 can be displaced towards the mounting support round seat 3 through the slope, so that the airtight connector 907 is pressed tightly in the second connecting air groove 906, ensuring the airtightness of the air passage connection; Furthermore, the composite sheet centering mechanism 10 includes a centering groove 1001, a mounting bracket 1002, a drive slide rod 1003, a reset guide post 1004, a second reset spring 1005, a hinge rod 1006, and a connecting rod 1007. A centering groove 1001 is provided on the inner side of the square detection bearing plate 4. Mounting brackets 1002 are movably arranged in an array within the centering groove 1001. The mounting brackets 1002 are symmetrically arranged along the composite sheet placement groove 5. A drive slide rod 1003 is provided between each mounting bracket 1002. Reset guide posts are fixedly installed in an array within the centering groove 1001. The reset guide post 1004 is movably inserted into the drive slide rod 1003. The drive slide rod 1003 is provided with a second reset spring 1005. The reset guide post 1004 and the second reset spring 1005 abut against each other. The drive slide rod 1003 is rotatably mounted with an array of hinge rods 1006. One end of the hinge rod 1006 is rotatably mounted on the mounting bracket 1002. The positioning arc blocks 7 are fixedly mounted on the upper side of the mounting bracket 1002. The positioning arc blocks 7 are opposite to the composite sheet placement groove 5. The drive slide rod 1003 is fixedly mounted on a set of connecting rods 1007. This structure is a clamping structure for the composite sheet by the positioning arc block 7. By pushing the connecting rod 1007, the driving slide rod 1003 is displaced, thereby making the hinge rod 1006 gradually vertical, so that the mounting bracket 1002 is engaged, and the positioning arc block 7 is relatively close to clamping the composite sheet. It should be noted that this clamping is only positioned once after the composite sheet is loaded, and then reset under the action of the second return spring 1005. It will not participate in subsequent detection. The driving slide rod 1003 extends beyond the edge of the square detection bearing plate 4, and the connecting rod 1007 needs to move towards the square detection bearing plate 4 to make the mounting bracket 1002 displace. When moving the square detection bearing plate 4, the connecting rod 1007 can be used as a handle. Furthermore, the composite sheet centering mechanism 10 also includes a light guide layer 1008. The center positions of the drive slide rod 1003, the mounting bracket 1002, and the positioning arc block 7 are all provided with light guide layers 1008. Light guide layers 1008 are fixedly installed on the upper and lower sides of the drive slide rod 1003. The light guide layer 1008 is sandwiched between the mounting bracket 1002 and the positioning arc block 7. The drive slide rod 1003 is partially exposed in its normal state, while the mounting bracket 1002 and the positioning arc block 7 are normally in a contracted and fitted state. Therefore, during inspection, the light guide layer 1008 is always in contact with the light. When the square inspection bearing plate 4 is illuminated by the light from the inspection head, the light guide layer 1008 is also illuminated. Through the reflection of the light guide layer 1008 itself, light passes through the centering slide groove 1001 and illuminates the side of the composite sheet placement groove 5, thereby achieving passive supplementary lighting for the side of the composite sheet. Working Principle: Before the testing operation begins, the square testing support plate 4 needs to be independently separated from the mounting support round base 3 to allow for the batch loading of composite sheets into the composite sheet placement slot 5. When the flip-limiting plates 6 on both sides are in the closed state, the operator or external automated mechanism pushes the connecting rod 1007 inward. The connecting rod 1007 directly drives the drive slide rod 1003 to move axially along the reset guide post 1004, overcoming the resistance of the second reset spring 1005 and compressing it during this process. As the drive slide rod 1003 moves, under the lever linkage of the hinge rod 1006, the positioning arc blocks 7 installed on the mounting bracket 1002 move towards each other in the centering groove 1001, thereby quickly circumferentially centering and positioning the diamond composite sheets placed in the composite sheet placement slot 5. When the external thrust is removed, under the energy release and rebound of the second reset spring 1005, the centering block automatically returns to its normal position along the centering groove 1001. At the same time, the flip-limiting plates 6 on the upper and lower sides of the square detection bearing plate 4 swing and close around the limit plate rotation axis 802 under the normal torque drive of the torsion spring 803, so that the flexible adsorption plate 804 is firmly pressed against the edge of the composite plate, and in conjunction with the fixed positioning arc block 7, the composite plate is stably clamped under normal conditions.

[0021] After the composite sheet is loaded, the square testing carrier plate 4 is inserted into the placement mounting groove 910 of the mounting support round seat 3 through the mounting frame 11 on one side. When inserted into place, the connecting clip frame 812 located on the side of the carrier plate will automatically fit onto the outside of the insertion head 815 at the end of the connecting block 814. The first wedge blocks 817 on both sides of the insertion head 815 are ejected outward under the elastic force of the first return spring 820, thus engaging in the inner groove of the connecting clip frame 812. At the same time as the mechanical docking, the sealing tube 905 on the mounting frame 11 is tightly inserted into the second connecting air groove 906, achieving accurate air path docking with the airtight connector 907. To ensure the airtightness of the whole machine in subsequent operations, the threaded clamping rod 914 is rotated at this time, causing it to move downward under the thread cooperation of the threaded sleeve 913, thereby pushing the second wedge block 915 downward in the receiving mounting groove 911. The inclined surface of the second wedge block 915 strongly presses the mounting frame 11 to move laterally, thereby pressing the mounting frame 11 into the inner side of the mounting groove 910 and locking the axial gap at the air passage connection. The square detection bearing plate 4 is disassembled in the same way.

[0022] When the external vision inspection system is activated and needs to inspect the surface defects of the diamond composite sheet, the telescopic motor 824 receives a control signal and performs a retraction action, pulling the second limiting arc frame 823 to generate axial displacement. The movement of the second limiting arc frame 823 will cause the limiting T-shaped round rod 822, which is slidably engaged inside it, to move, thereby axially pulling the connecting block 814 and the connecting frame 812 connected by the insertion head 815. The connecting frame 812 pulls the rack 807, which is located in the sliding guide frame 806, to translate through the connecting rope 809. During this process, the connecting rope 809 is guided and constrained by the guide rope ring 808 to ensure accurate transmission direction. The rack 807 drives the gear 805 to rotate through tooth meshing, thereby overcoming the resistance of the torsion spring 803 and driving the upper flipping limiting piece 6 to flip upward into a vertical state. At this point, the upper limiting plate completely avoids the upper surface and edge of the composite film, leaving an unobstructed and complete optical detection space for the camera and light source above. Meanwhile, the lower flip limiting plate 6, since it is not under tension, remains in a normally closed state under the action of the torsion spring to support the bottom of the composite film.

[0023] While both sides of the flip-limiting plates 6 are closed, the air pump 908 starts and reverses the air path through the four-way valve 909, creating negative pressure in the corresponding gas connection pipe 904 on the lower side. The negative pressure airflow is conducted along the first connecting air groove 903 and the inner air groove 902 to the adsorption air hole 901 of the lower flexible adsorption plate 804, adsorbing and fixing the composite plate to the bottom surface of the composite plate placement groove 5. This negative pressure clamping with unobstructed edges ensures a more complete field of view. Then, the upper flip-limiting plate 6 opens, and the four-way valve 909 also controls the upper air path to connect with the positive pressure exhaust port of the air pump 908, so that the positive pressure airflow is ejected from the upper adsorption air hole 901, performing pneumatic cleaning on the upper surface and edges of the composite plate to be tested, quickly blowing away the wear debris, oil stains or water mist attached to the surface. Subsequently, the drive motor 2 starts, driving the mounting support round seat 3 and the square detection carrier plate 4 to reciprocate or rotate at a certain angle to change the detection tilt angle. During rotation, because the limiting T-shaped rod 822 is slidably installed within the annular track formed by the first limiting arc frame 821 and the second limiting arc frame 823, the tilt angle change of the disc is completely unaffected by the pull rope drive mechanism. After the composite sheet changes tilt angle with the disc, surface defects such as microcracks and chipped edges will produce obvious light and dark contrasts under changes in external lighting, making it easy for the vision camera to accurately capture them. At the same time, the light guide layer 1008 located in the interlayer reflects the detection light projected at a large angle from the outside a second time, and the light passes through the centering groove 1001 to directly illuminate the side edge of the composite sheet, achieving passive edge lighting without the need for additional light sources. After the inspection and cleaning of this side are completed, the telescopic motor 824 resets, the upper flip limit plate 6 changes to the closed state, and the drive motor 2 drives the mounting support round base 3 to rotate 180 degrees. At this time, the signals are swapped through the four-way valve 909 and the telescopic motor 824. The limit plate that was originally on the lower side turns to the upper side and is pulled open, while the limit plate that was originally on the upper side turns to the lower side to close and switch to the negative pressure adsorption and fixation state. The same linkage logic is used to complete the unobstructed tilt angle inspection of the other side of the composite sheet, thereby realizing efficient and comprehensive double-sided automated defect inspection.
