Description

Technical Field

[0001] The present invention relates to the technical field of acrylic plate repair, and in particular to a visual inspection system and method for acrylic plate repair. Background Art

[0002] Acrylic sheet, scientifically known as polymethyl methacrylate (PMMA) sheet, is an important thermoplastic that was developed earlier. It has high transparency, light transmittance of more than 92%, good chemical stability and weather resistance, easy dyeing, easy processing, and beautiful appearance. Therefore, it is widely used in many fields such as construction, advertising, handicrafts, furniture, etc. During the production process, acrylic sheet uses a visual inspection system to accurately identify scratches, bubbles, impurities on the surface of acrylic sheet, as well as cracks, uneven stress and other defects inside, to ensure that the product meets quality standards. By timely discovering and marking defective products, they can be prevented from flowing into subsequent production links or markets, reducing product after-sales risks.

[0003] When inspecting acrylic sheets, existing visual inspection mechanisms can only detect the surface of acrylic sheets and cannot achieve all-round inspection. In addition, when inspecting the other side of the acrylic sheet, the position and angle of the acrylic sheet to be inspected need to be adjusted, which increases the difficulty of inspecting the acrylic sheet. Since some inspection mechanisms need to clamp the acrylic sheet first, this also causes the clamping parts to contact and cover part of the surface of the acrylic sheet, making it difficult to complete the visual inspection and identification of the flaws and internal defects of the acrylic sheet at one time, thereby affecting the inspection effect of the acrylic sheet and reducing the overall inspection efficiency. Summary of the invention

[0004] The present invention provides a visual inspection system and method for acrylic plate repair, which are used to solve the problem in the prior art that acrylic plates are difficult to be fully inspected and covered parts cannot be visually inspected, resulting in low efficiency of visual inspection of acrylic plates.

One end of the column is movably embedded in the surface of the support frame, and the other end is movably connected to the two clamping arms. The two clamping blocks are respectively fixedly installed at one end of the two clamping arms.

[0013] According to a visual inspection system for acrylic plate repair provided by the present invention, the transmission mechanism includes a rotating rod, gear three, a "U"-shaped tooth plate, bevel gear one, bevel gear two, a rotating rod, a second helical gear, a support rod, and a telescopic column. Gear three is fixedly connected to the surface of the rotating rod. The "U"-shaped tooth plate is fixedly connected to the sleeve and meshes with gear three.

One end of the rotating rod is fixedly connected to bevel gear two, and the other end is rotatably mounted on the telescopic column, and the telescopic column is fixedly mounted on the surface of the inspection table. The second helical gear is movably sleeved on the rotating rod and rotatably connected to the support rod. The support rod is movably sleeved on the outer surface of the rotating rod.

[0014] According to a visual inspection system for acrylic plate repair provided by the present invention, the adjustment device includes a rotating frame, two first bevel gears, an "L"-shaped rod, a second bevel gear, a third bevel gear, a first gear, a fourth bevel gear, a second gear, a third gear, three driving gears, and three driving motors. The rotating frame is rotatably installed inside the installation bin. The two first bevel gears are rotatably connected to the two ends of the rotating frame respectively. The "L"-shaped rod is fixedly connected to one of the first bevel gears, and the other end is rotatably connected to the second bevel gear.

[0015] According to the present invention, a visual inspection system for acrylic plate repair also includes a conveying device, two shells, and a marking device. The conveying device is arranged on the inner side of the detection table. A plurality of placement seats are installed in an array on the surface of the conveying device. The two shells are fixedly mounted on the two ends of the upper surface of the detection table. Two sliding rods are fixedly connected to the inside of the two shells, and a slide plate is movably mounted on the surface of each of the two sliding rods. The two slide plates are fixedly connected to the propulsion device 2 and the propulsion device 1, respectively. The marking device is fixedly mounted on the upper surface of the detection table and is located on one side of the detection device. The marking device is used to mark the acrylic plate.

[0016] On the other hand, the present invention also provides a visual inspection method for acrylic plate repair, comprising the following steps: Place the acrylic sheet on the placement seat. When the conveyor operates, it will drive the acrylic sheet to the bottom of the shelf. The conveyor immediately stops transmitting, and the visual camera detects the acrylic sheet. The optical inspection mechanism provides light source. Once the propulsion device starts operating, it drives the clamping mechanism at one end close to one side of the acrylic sheet. The electric rod starts to make the clamping mechanism clamp one side of the acrylic sheet.

[0017] Next, motor one starts, driving propulsion device one and propulsion device two to rise synchronously. When propulsion device one rises, the rack descends and contacts the first spur gear, causing the first spur gear to rotate, driving the clamped acrylic plate to flip, so that the visual camera detects the flipped side.

[0018] When the propulsion device 1 rises, it drives the "U"-shaped tooth plate to mesh with gear 3 and rotates, and drives bevel gear 1 and bevel gear 2 to rotate, so that the rotating rod drives the second helical gear to rotate. When the other clamping mechanism extends, the first helical gear meshes with the second helical gear, and the first helical gear rotates, driving the screw to rotate, and then the two clamping blocks are clamped on the other side of the acrylic plate.

[0019] After the clamping is completed, the propulsion device 1 is retracted. The motor 1 reverses, and the retracted propulsion device 1 drives the tooth block on the other side of the "U"-shaped tooth plate to mesh with gear 3. When the propulsion device 2 descends, the "U"-shaped tooth plate falls and drives gear 3 to rotate, and the second spur gear meshes with the rack. The clamping mechanism on the other side of the clamp drives the acrylic plate to flip, and then the propulsion device 2 continues to drive the first helical gear to mesh and rotate with the second helical gear, allowing the clamping mechanism to loosen the acrylic plate.

[0020] The acrylic plate slowly falls onto the placement seat, and the inspected acrylic plate is conveyed by the conveying device. When the defective acrylic plate passes under the marking device, the visual camera transmits the detected defect information to the control terminal, and the control terminal starts the marking device to mark the defective acrylic plate.

[0021] The present invention provides a visual inspection system and method for repairing acrylic plates. By starting the inspection device, one clamping mechanism can first clamp one side of the acrylic plate, and then drive it to flip under the drive of the propulsion rotation mechanism. The visual camera detects the exposed surface. After completing one flip, another clamping mechanism adjusted in advance takes over to expose the part blocked by the first clamping mechanism, and then flips again to detect the originally blocked surface, thereby achieving a comprehensive scan. Through the relay clamping and flipping method, the visual camera realizes all-round and no-dead-angle inspection of the acrylic plate, can accurately identify minor flaws and potential internal defects, strictly control product quality, and effectively improve production efficiency.

[0022] The present invention provides a visual inspection system and method for acrylic plate repair, which can adjust the angle, rotation and light intensity of the light in all aspects by setting an adjustment device. In the process of light source detection for acrylic plates, various angles of the light can be flexibly adjusted according to the detection requirements, which greatly improves the quality and reliability of the detection work, ensures that defects on acrylic plates can be accurately found, and fully meets the high-quality production detection requirements.

[0023] The present invention provides a visual inspection system and method for repairing acrylic plates. A propulsion device 1 and a propulsion device 2 are arranged on every two sliding bars to move up and down. During the inspection process, when the acrylic plate needs to be clamped and turned over, the propulsion device 1 and the propulsion device 2 need to be stably lifted and lowered, which can ensure that the device always maintains stable movement in the vertical direction during the movement, so that the clamping mechanism can be accurately positioned on both sides of the acrylic plate, which not only improves the accuracy and reliability of the inspection operation, but also effectively prolongs the service life of the equipment and reduces wear and failure caused by shaking or unstable movement of components.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 3 As shown, the present invention provides a visual inspection system for acrylic plate repair, comprising: an inspection table 1, a frame plate 2, a visual camera 21, a conveying device 3, two positioning frames 4, a detection device 5, an optical inspection mechanism 6, two housings 7, and a marking device 8.

[0029] The frame 2 is fixedly mounted on the upper surface of the test bench 1. The four legs at the bottom of the frame 2 are firmly fixed to the surface of the test bench 1, so that the visual camera 21 can be accurately mounted on the top of the inner side of the frame 2. The visual camera 21 analyzes the collected images through advanced image processing algorithms, thereby accurately extracting the defect features of the acrylic plate, such as scratches, bubbles, impurities, etc.

[0030] The conveying device 3 is arranged on the inner side of the detection table 1. A plurality of placement seats 31 are installed in an array on the surface of the conveying device 3. On the surface of the conveying device 3, a plurality of placement seats 31 are distributed in an array. The placement seats 31 are made of a silicone pad with soft properties. This silicone pad can not only support and place the acrylic plate, but also bend accordingly according to the changes in the conveying path during the operation of the conveying device 3 due to its own flexibility. It ensures that during the conveying process, even if there is a certain curvature or undulation in the conveying path, the placement seat 31 can still be firmly installed on the conveying device 3.

[0031] The two positioning frames 4 are respectively fixedly mounted on both sides of the upper surface of the detection platform 1. The two positioning frames 4 are respectively in different shapes and are used to support and position the detection device 5.

[0032] like Figure 4-Figure 8 As shown, the detection device 5 includes a driving mechanism 51, two lifting mechanisms 52, a propulsion rotating mechanism 1 53, a propulsion rotating mechanism 2 54, two clamping mechanisms 55, and a transmission mechanism 56. The driving mechanism 51 is arranged on two positioning frames 4. Both lifting mechanisms 52 are fixedly connected to the driving mechanism 51. The propulsion rotating mechanism 1 53 is fixedly installed on one of the lifting mechanisms 52, and the propulsion rotating mechanism 2 54 is fixedly installed on the other lifting mechanism 52. The two clamping mechanisms 55 are respectively arranged at one end of the propulsion rotating mechanism 1 53 and the propulsion rotating mechanism 2 54. The transmission mechanism 56 is arranged on one side of the propulsion rotating mechanism 1 53 and the propulsion rotating mechanism 2 54.

[0033] The detection device 5 continuously transmits the acrylic plate through the transmission device 3 to achieve a full range of detection operations. The driving mechanism 51 is closely connected with the two lifting mechanisms 52 to form a stable connection structure. When the driving mechanism 51 is started, the two lifting mechanisms 52 are driven at the same time by power output to ensure that the two operate synchronously. When the driving mechanism 51 is turned on, the two propulsion rotating mechanisms 1 53 and the propulsion rotating mechanism 2 54 can achieve precise synchronous lifting and lowering actions driven by the lifting mechanism 52. At the opposite ends of the propulsion rotating mechanism 1 53 and the propulsion rotating mechanism 2 54, a clamping mechanism 55 is respectively provided. The two clamping mechanisms 55 have clear division of labor and are specifically used to perform precise clamping operations on the left and right sides of the acrylic plate to ensure that the acrylic plate remains stable during the detection process.

[0034] A linkage mechanism is established between the transmission mechanism 56 and the propulsion rotation mechanism 1 53 and the propulsion rotation mechanism 2 54. When the transmission mechanism 56 is started, it can cooperate with the propulsion rotation mechanism 1 53 and the propulsion rotation mechanism 2 54 to perform a clamping and flipping action on the acrylic plate in the transmission process. In this way, all surfaces and angles of the acrylic plate can be fully exposed within the detection range of the visual camera 21, thereby achieving a more comprehensive and detailed detection effect, greatly improving the accuracy and reliability of the detection.

[0035] The driving mechanism 51 includes a motor 511, two pulleys 512, and a transmission belt 513. The motor 511 is fixedly mounted on the surface of one of the positioning frames 4, and one of the pulleys 512 is fixedly connected to the output end of the motor 511, and the other pulley 512 is rotationally connected to the other positioning frame 4. The transmission belt 513 is wound and connected with the two pulleys 512. The output end of the motor 511 is fixedly connected to the pulley 512. When the motor 511 is started, the rotating power outputted by the motor 511 can directly drive the pulley 512 to rotate smoothly. In this mechanism, the two pulleys 512 are designed with exactly the same shape and size specifications, and are tightly wound and connected by the transmission belt 513. When the motor 511 is started and drives the pulley 512 connected thereto to rotate, due to the transmission effect of the transmission belt 513, the other pulley 512 can be driven synchronously, thereby realizing the synchronous rotation of the two pulleys 512. Through this synchronous rotation mechanism, a stable and consistent power input can be provided to the subsequent associated lifting mechanism 52, thereby ensuring the stability and coordination of the entire detection device 5 during operation.

[0036] The lifting mechanism 52 includes two pulleys 521, a transmission belt 522, and a rack 523. The pulley 521 is rotatably mounted on the positioning frame 4 and is fixedly connected to one of the pulleys 512. The transmission belt 522 is wound around the two pulleys 521. The rack 523 is fixedly connected to one side of the transmission belt 522.

[0037] The whole device adopts two lifting mechanisms 52, and one of the two pulleys 512 is installed corresponding to the two pulleys 521. When the driving mechanism 51 is started, the power output by the motor 511 drives the pulley 512 to rotate. With this corresponding installation structural design, the synchronous transmission of the two lifting mechanisms 52 can be achieved. Each pulley 521 is connected to the rotation through the rotating shaft support structure, which enhances the stability of the two lifting mechanisms 52 during operation and effectively reduces the error caused by shaking or imbalance. The surface of each two pulleys 521 is tightly wound and connected by a transmission belt 522. When one of the pulleys 521 receives the driving force from the pulley 512, it can transmit the power to the other pulley 521 through the transmission belt 522, so as to achieve efficient power transmission and synchronous operation. The motor 511 uses a forward and reverse motor. The motor can accurately generate forward or reverse rotation according to the actual detection requirements. The transmission belt 522 wound and connected on the two pulleys 521 has a unique lifting feature. With the forward and reverse rotation of the motor 1 511 , the transmission belt 2 522 can rise or fall regularly, thereby driving the rack 523 that closely cooperates with it to perform a lifting operation.

[0038] The propulsion rotating mechanism 1 53 includes a propulsion device 1 531, a sleeve 532, a first straight gear 533, and an electric rod 534. The propulsion device 1 531 is fixedly connected to one of the transmission belts 2 522. The sleeve 532 is fixedly mounted on one end of the propulsion device 1 531. The first straight gear 533 is rotatably connected to one end of the sleeve 532. The electric rod 534 is fixedly connected to one end of the first straight gear 533.

[0039] The propulsion device 1 531 is composed of an external mounting shell and an internal electric telescopic rod. Its external mounting shell is firmly fixedly connected to the transmission belt 2 522 on one of the lifting mechanisms 52. When the lifting mechanism 52 is driven to drive the transmission belt 2 522 to move, the propulsion device 1 531 on the transmission belt 2 522 can be synchronously prompted to move accordingly. The sleeve 532 is firmly mounted on the top of the electric telescopic rod of the propulsion device 1 531. When the electric telescopic rod starts to extend, it will synchronously drive the sleeve 532 to move forward in a predetermined direction by virtue of the characteristics of the rigid connection. At the same time, the first spur gear 533 connected to the sleeve 532 will also be pushed forward. When the transmission belt 2 522 starts to slide under the action of the lifting mechanism 52, the propulsion device 1 531 connected to one side of the transmission belt 2 522 will climb upward. At this time, the rack 523 on the other side of the transmission belt 2 522 will be driven to move downward. When the propulsion device 1 531 moves upward, it can prompt the first spur gear 533 to approach and mesh closely with the rack 523. Under the interaction between the toothed structure of the rack 523 and the first spur gear 533, the first spur gear 533 begins to rotate. Since there is a specific connection relationship between the first spur gear 533 and the clamping mechanism 55, the rotation of the first spur gear 533 will drive the clamping mechanism 55 to flip. The overall width of the rack 523 is designed to match the maximum extension distance of the propulsion device 1 531. During the transmission of the acrylic plate, the propulsion device 1 531 can drive the clamping mechanism 55 to accurately extend to one side of the acrylic plate. At this time, the extension distance of the first spur gear 533 can just make it located within the tooth surface range of the rack 523, thereby achieving stable meshing. When the clamping mechanism 55 clamps one side of the acrylic plate and the surface is scanned by the visual camera 21, the coordinated operation of the transmission system can enable the clamping mechanism 55 to drive the acrylic plate to flip as a whole, so that the visual camera 21 can fully detect the other side of the acrylic plate, ensuring that there is no blind spot in the detection work.

[0040] The propulsion rotating mechanism 2 54 includes a propulsion device 2 541, a second spur gear 542, an assembly frame 543, a first helical gear 544, a screw rod 545, a connecting plate 546, and a telescopic support rod 547. The propulsion device 2 541 is fixedly connected to another transmission belt 2 522. The second spur gear 542 is rotatably mounted on one end of the propulsion device 2 541. The assembly frame 543 is fixedly connected to the second spur gear 542. One side of the first helical gear 544 is rotatably connected to the assembly frame 543, and the other side is fixedly connected to the screw rod 545. The connecting plate 546 is fixedly connected to the propulsion device 2 541. Both telescopic support rods 547 are fixedly connected to the connecting plate 546, and the bottoms of the two telescopic support rods 547 are fixedly mounted on the detection platform 1.

[0041] The structure of the second propulsion device 541 is consistent with that of the first propulsion device 531. In the entire detection system, it also undertakes the task of propulsing and moving the clamping mechanism 55. The second propulsion device 541 is also firmly fixed on one side of the transmission belt 522. When the two lifting mechanisms 52 start working under the drive of the driving mechanism 51, the second propulsion device 541 and the first propulsion device 531 can achieve precise synchronous lifting and lowering operation. This synchronization mechanism ensures that when the acrylic plate is tested, the clamping mechanisms 55 on both sides can make corresponding position adjustments at the same time and at the same rate, providing a stable and coordinated basic support for the subsequent detection process. One side of the second spur gear 542 is connected and fixed to the assembly frame 543, and the other side is connected to the second propulsion device 541. When the second spur gear 542 rotates under the drive of an external force, it will synchronously drive the structure connected to the assembly frame 543 to produce a flipping operation. This flipping action realizes a flipping operation for the clamped acrylic plate in the subsequent detection process, so as to facilitate a more comprehensive detection.

[0042] On the inner side of the assembly frame 543, the first helical gear 544 is installed through a rotating structure. A screw rod 545 is fixedly connected to the other side of the first helical gear 544, and the screw rod 545 is connected to the corresponding clamping mechanism 55. When the first helical gear 544 rotates under the drive of the transmission system, the screw rod 545 will rotate accordingly. Due to the connection method between the screw rod 545 and the clamping mechanism 55, the rotation of the screw rod 545 can be converted into a linear propulsion motion of the clamping mechanism 55, so as to accurately propel and clamp the clamping mechanism 55 to one side of the acrylic plate, thereby achieving stable clamping of the acrylic plate. In summary, the propulsion device 2 541 and its related components work in coordination with the propulsion device 1 531 to jointly realize all-round and efficient detection of the acrylic plate, greatly improving the accuracy and reliability of the detection work, and ensuring strict control of product quality during the production process.

[0043] like Fig.10 As shown, the clamping mechanism 55 includes a support frame 551, a column 552, two clamping arms 553, and two clamping blocks 554. One end of the column 552 is movably embedded in the surface of the support frame 551, and the other end is movably connected to the two clamping arms 553. The two clamping blocks 554 are fixedly installed at one end of the two clamping arms 553 respectively.

[0044] In the detection device 5, two clamping mechanisms 55 are provided, which cooperate with each other to ensure the stable clamping and detection operation of the acrylic plate. One of the pillars 552 passes through the support frame 551 in a movable through-through manner, and a thread groove adapted to the screw rod 545 is opened inside the pillar 552. When the screw rod 545 rotates under the drive of the transmission system, based on the transmission principle of the thread, the pillar 552 will produce a propulsion movement along the axial direction of the screw rod 545. Thereby, the pillar 552 can flexibly adjust its position under the control of the screw rod 545, providing accurate displacement support for subsequent clamping actions. The other pillar 552 is tightly connected to the electric rod 534. When the electric rod 534 is started, one end of the pillar 552 connected to the electric rod 534 is telescopically moved. In this way, the pillar 552 can also quickly adjust its position according to the detection requirements to meet the requirements of clamping acrylic plates of different sizes or positions.

[0045] The support frame 551, as the core overall structure of the clamping mechanism 55, provides stable support and guidance for the movement of the column 552. The column 552 can move flexibly throughout the surface of the support frame 551 to ensure its stability during movement. On both sides of the support connection part at one end of the column 552, there are respectively provided with exquisite clamping arms 553. The clamping arms 553 use multiple groups of support rods and are rotatably connected through a movable shaft. This unique structural design enables the two clamping arms 553 to achieve flexible opening and closing movements driven by the column 552, thereby forming an effective clamping function between the two clamping arms 553. On the clamping end surfaces of the two clamping arms 553, clamping blocks 554 are respectively fixedly installed. The clamping blocks 554 are made of rubber material with good anti-slip properties. When the clamping mechanism 55 is working, the clamping block 554 can fit tightly against one side of the acrylic plate, which can not only provide sufficient friction to ensure that the acrylic plate does not slide during the clamping process, but also effectively avoid scratching or damaging the surface of the acrylic plate.

[0046] The transmission mechanism 56 includes a rotating rod 561, a gear three 562, a "U"-shaped toothed plate 563, a bevel gear one 564, a bevel gear two 565, a rotating rod 566, a second helical gear 567, a support rod 568, and a telescopic column 569. The gear three 562 is fixedly connected to the surface of the rotating rod 561. The "U"-shaped toothed plate 563 is fixedly connected to the sleeve 532 and meshes with the gear three 562. The bevel gear one 564 is fixedly connected to the other end of the rotating rod 561 and meshes with the bevel gear two 565. One end of the rotating rod 566 is fixedly connected to the bevel gear two 565, and the other end is rotatably mounted on the telescopic column 569, and the telescopic column 569 is fixedly mounted on the surface of the detection platform 1. The second helical gear 567 is movably sleeved on the rotating rod 566 and rotatably connected to the support rod 568. The support rod 568 is movably sleeved on the outer surface of the rotating rod 566.

[0047] The "U"-shaped tooth plate 563 is constructed in a "U" shape. On both sides of the inner wall of the "U"-shaped tooth plate 563, multiple tooth blocks are evenly distributed. The rotating rod 561 uses a stable support structure to ensure that the gear three 562 can be flexibly rotated and installed. The gear three 562 is properly located on the inner side of the "U"-shaped tooth plate 563, and can be meshed and connected with the two sides of the inner wall of the "U"-shaped tooth plate 563 at different positions according to the transmission operation of the propulsion device one 531. When the propulsion rotating mechanism one 53 is driven to rise by an external driving force, the "U"-shaped tooth plate 563 fixedly connected to the propulsion rotating mechanism one 53 will move up and down synchronously. In this process, one side of the inner wall of the "U"-shaped tooth plate 563 will be in close contact with the tooth surface of the gear three 562 and push it, thereby causing the gear three 562 to rotate in the forward direction. When the "U"-shaped tooth plate 563 descends, the other side of the inner wall will play a role, pushing the gear three 562 to flip in the opposite direction. Through this reciprocating motion, the transmission operation of the entire transmission mechanism 56 is realized.

[0048] When gear three 562 rotates continuously under the drive of the "U"-shaped tooth plate 563, its power is transmitted to the bevel gear one 564 that is tightly meshed with it. Bevel gear one 564 is then driven, thereby driving bevel gear two 565 that is meshed with it to rotate. Since bevel gear two 565 is fixedly connected to the rotating rod 566, the rotating rod 566 can achieve overall follow-up rotation under the drive of bevel gear two 565. The second helical gear 567 is installed on the rotating rod 566 in a tightly sleeved manner. On the surface of the rotating rod 566, a plurality of limit strips are designed, and these limit strips cooperate with the internal structure of the second helical gear 567, so that when the rotating rod 566 rotates, the sleeved second helical gear 567 can rotate synchronously with the rotation of the rotating rod 566, thereby ensuring the accuracy of power transmission.

[0049] The support rod 568 firmly connects the propulsion device 2 541 and the second helical gear 567. A telescopic column 569 is installed at the bottom of the rotating rod 566. The telescopic column 569 can be flexibly adjusted according to the needs to ensure that the height of the second helical gear 567 can always accurately follow the height change of the propulsion rotating mechanism 2 54. In this way, the second helical gear 567 can be precisely meshed with the first helical gear 544. When the rotating rod 566 is driven to rotate under the drive of the transmission system, the second helical gear 567 will be driven synchronously, and then meshed rotation is formed with the first helical gear 544.

[0050] like Figure 9-10 As shown, the optical inspection mechanism 6 includes a mounting chamber 61, an adjusting device 62, and a lighting lamp 63. The mounting chamber 61 is fixedly mounted on the top of the frame plate 2. The adjusting device 62 is arranged in the mounting chamber 61. The lighting lamp 63 is fixedly connected to the adjusting device 62.

[0051] The main function of the optical inspection mechanism 6 is to provide an accurate and multi-angle light source for the acrylic plate during the inspection process to assist in the inspection work. The installation chamber 61 provides an installation space for the adjustment device 62. The adjustment device 62 can adjust the angle of the reference lamp 63.

[0052] In the actual detection process, acrylic plates of different types and specifications may require light sources at different angles to highlight potential defects inside or on the surface. As a direct output device of the light source, the light 63 can generate light sources at various angles under the control of the adjustment device 62. These light sources shine evenly and accurately on the acrylic plate, and through optical principles such as reflection and refraction, every detail of the acrylic plate can be clearly displayed. For example, when it is necessary to detect fine scratches on the surface of the acrylic plate, the light 63 can be adjusted to a specific low angle through the adjustment device 62. At this time, the light source shines on the surface of the acrylic plate in an oblique manner, and the scratches will be clearly visible due to the difference in light reflection. If bubbles or impurities inside the acrylic plate are to be detected, the light 63 can be adjusted to vertical illumination or a specific angle combination, and the propagation characteristics of light inside the acrylic plate can be used to clearly present the outlines of bubbles and impurities.

[0053] The adjusting device 62 includes a rotating frame 621, two first bevel gears 622, an "L"-shaped rod 623, a second bevel gear 624, a third bevel gear 625, a first gear 626, a fourth bevel gear 627, a second gear 628, a third gear 629, three driving gears 6210, and three driving motors. The rotating frame 621 is rotatably mounted inside the mounting chamber 61. The two first bevel gears 622 are rotatably connected to the two ends of the rotating frame 621 respectively. The "L"-shaped rod 623 is fixedly connected to one of the first bevel gears 622, and the other end is rotatably connected to the second bevel gear 624. The lighting 63 is fixedly connected to one end of the second bevel gear 624. The second bevel gear 624 and the third bevel gear 625 are both meshed with the other first bevel gear 622. The top of the third bevel gear 625 is fixedly connected with the first gear 626. The fourth bevel gear 627 is meshed with one of the first bevel gears 622, and the other end is fixedly connected to the second gear 628. A third gear 629 is fixedly mounted on one end of the rotating frame 621. The first gear 626, the second gear 628 and the third gear 629 are respectively meshed with the three driving gears 6210, and the tops of the three driving gears 6210 are fixedly connected to the output end of the driving motor.

[0054] The rotating frame 621 is composed of a pipe column and connecting rod frames symmetrically distributed on both sides. The pipe column is installed in the installation chamber 61 in a movable embedded manner. This design not only ensures the stability of the pipe column, but also gives it the characteristic of flexible rotation. One end of the pipe column passes through the installation chamber 61 and is firmly fixedly connected to the third gear 629. When an external power source acts on the third gear 629 and drives it to start rotating, the connection between the two can drive the rotating frame 621 to achieve overall circular rotation.

[0055] Two first bevel gears 622 are rotatably mounted on the inner sides of both ends of the rotating frame 621. The two first bevel gears 622 are different in size. One of the first bevel gears 622 is completely matched with the fourth bevel gear 627 in shape and size, and the two are precisely meshed, thereby ensuring that power can be efficiently transmitted between them. The other first bevel gear 622 is consistent with the second bevel gear 624 and the third bevel gear 625 in specifications, and is tightly meshed with the two bevel gears respectively. One end of the "L"-shaped rod 623 is fixedly connected to one of the first bevel gears 622, and the other end is sleeved on the fixed rod connected to the bottom end of the second bevel gear 624. The light 63 is firmly connected to the second bevel gear 624 through the fixed rod. When the second bevel gear 624 starts to rotate under the drive of the first bevel gear 622, it can synchronously drive the light 63 to rotate around the axis of the fixed rod. This process enables the light 63 to flexibly adjust the irradiation angle according to actual detection needs, providing a variety of light source irradiation directions for the detection of acrylic plates.

[0056] A fixed rod is connected to the top side of the fourth bevel gear 627. The fixed rod runs through the interior of the rotating frame 621 and is connected to the second gear 628. When the external drive motor outputs power to drive the second gear 628 to start rotating, based on the connection with the fixed rod, the rotational motion of the second gear 628 will be directly transmitted to the fourth bevel gear 627, driving it to rotate synchronously. Since the fourth bevel gear 627 is meshed with one of the first bevel gears 622, the rotation of the fourth bevel gear 627 immediately drives the first bevel gear 622 to rotate, and the "L"-shaped rod 623 will change its angle accordingly. One end of the "L"-shaped rod 623 is sleeved on the fixed rod connected to the bottom end of the second bevel gear 624, and the other end is fixed to the first bevel gear 622. When the first bevel gear 622 rotates, the "L"-shaped rod 623 will push the second bevel gear 624 to rotate a certain angle around its fixed axis. Since the lamp 63 is firmly connected to the second bevel gear 624 through the fixing rod, the rotation of the second bevel gear 624 will synchronously drive the lamp 63 to adjust its tilt angle, thereby being able to produce tilted illumination of the acrylic plate, meeting the needs of detecting surface or internal defects of the acrylic plate at different angles.

[0057] The top of the third bevel gear 625 is also connected by a fixed rod. The fixed rod runs through the inside of the fixed rod connected to the fourth bevel gear 627, and an independent transmission path is realized while ensuring a compact structure. One end of the fixed rod on the third bevel gear 625 is firmly connected to the first gear 626. When the driving gear 6210 meshing with the first gear 626 is started, the rotation of the driving gear 6210 will drive the first gear 626 to rotate, and then drive the third bevel gear 625 to rotate by virtue of the connection of the fixed rod. Since the third bevel gear 625 is tightly meshed with another first bevel gear 622, and the first bevel gear 622 is meshed with the second bevel gear 624, the rotation of the third bevel gear 625 will synchronously drive the group of first bevel gears 622 and second bevel gears 624 to rotate, and finally the body of the light 63 is rotated around its mounting axis. Through this rotation, the light 63 can illuminate its own light source of different strengths on the acrylic plate. For example, when detecting bubbles or impurities inside an acrylic plate, by adjusting the rotation angle of the lamp 63 and utilizing the refraction and scattering characteristics of light of different intensities, the position and shape of the bubbles or impurities can be more clearly presented.

[0058] When the driving gear 6210 meshing with the third gear 629 is driven, the power of the driving gear 6210 will be transmitted to the third gear 629. Because the third gear 629 is fixedly connected to the column of the rotating frame 621, the rotation of the third gear 629 will drive the rotating frame 621 body to rotate as a whole. The first bevel gear 622 installed on the inner side of both ends of the rotating frame 621 and the light 63 connected thereto and other components will rotate accordingly. The adjustment of the flip angle of the entire light 63 is realized, and the light 63 can be adjusted to various angles of illumination light, so as to accurately illuminate various defects on the acrylic plate. For example, when detecting a large area of ​​acrylic plate, the light 63 can be adjusted to a larger tilt angle to achieve uniform illumination of a larger range of acrylic plates, thereby improving detection efficiency and accuracy.

[0059] The two housings 7 are fixedly mounted at both ends of the upper surface of the detection platform 1. Two slide bars 71 are fixedly connected to the inside of the two housings 7, and slide plates 72 are movably sleeved on the surfaces of the two slide bars 71. The two slide plates 72 are fixedly connected to the propulsion device 2 541 and the propulsion device 1 531, respectively. The marking device 8 is fixedly mounted on the upper surface of the detection platform 1 and is located on one side of the detection device 5. The marking device 8 is used to mark the acrylic plate.

[0060] Two slide bars 71 are fixed inside each housing 7, and slide bars 72 are movably sleeved on the surfaces of the two slide bars 71. The inner diameter of the slide bar 72 is precisely matched with the outer diameter of the slide bar 71, which can not only ensure that the slide bar 72 can move up and down smoothly on the slide bar 71, but also effectively limit the displacement of the slide bar 72 in other directions, ensuring the accuracy of its motion trajectory. The propulsion device 2 541 and the propulsion device 1 531 are respectively fixed to the corresponding two slide bars 72 through a specific connection method. When the propulsion device 1 531 and the propulsion device 2 541 are driven to perform lifting operations, the slide bar 72 will move with the propulsion device. Since the slide bar 72 is movably sleeved on the slide bar 71, the slide bar 71 will play a good limiting role in the movement of the slide bar 72. The slide bar 72 can only slide up and down along the axial direction of the slide bar 71, effectively avoiding problems such as shaking and offset caused by external interference or its own motion inertia.

[0061] When the acrylic plate is orderly transmitted through the conveying device 3, considering the accuracy of subsequent detection, the corresponding spacing space is reserved between each acrylic plate. On the shelf 2, a sensor is installed, which can accurately capture the position information of the acrylic plate. When the acrylic plate is smoothly transmitted to the bottom of the sensor along with the conveying device 3, the sensor will immediately trigger the detection sensing mechanism. At this time, the conveying device 3 receives the command issued by the control system, and quickly and accurately drives the positioned acrylic plate to stop between the preset positions of the detection device 5. Then, the detection device 5 is quickly started, and the propulsion device 1 531 and the propulsion device 2 541 inside it work together to accurately clamp the two sides of the acrylic plate. Subsequently, by realizing the flipping action of the acrylic plate, the visual camera 21 performs all-round image acquisition of the acrylic plate during the flipping process.

[0062] The visual camera 21 uses advanced image recognition algorithms and high-resolution imaging technology to quickly and accurately identify whether there are defects and cracks in the acrylic plate. Once a defect is detected, the visual camera 21 will immediately transmit the detailed information of the defective acrylic plate, including the location, shape, size, etc. of the defect, to the control system in the form of a digital signal. As the core hub of the entire detection process, the control system has powerful data processing and command sending capabilities. After receiving the command from the visual camera 21, the control system quickly analyzes and processes the information and immediately starts the marking device 8. The marking device 8 uses inkjet technology. When the defective acrylic plate moves slowly to the bottom of the marking device 8 along with the conveying device 3, the marking device 8 accurately marks the surface of the acrylic plate according to the marking mode and parameters preset by the control system. After the marking is completed, the defective acrylic plate continues to be stably transmitted to the next conveyor through the conveying device 3. On the next conveyor, the staff can carry out targeted treatment of the defective acrylic plate according to the marking information, such as repair, scrapping, etc.

[0063] In this embodiment, by starting the detection device 5, one of the clamping mechanisms 55 can first clamp the acrylic plate on one side, and then drive it to flip under the drive of the propulsion rotation mechanism 53, and the visual camera 21 detects the exposed surface. After completing one flip, another clamping mechanism 55 that has been adjusted in advance takes over, clamps the part blocked by the first clamping mechanism 55, and then flips again to expose the originally blocked surface, thereby achieving a comprehensive scan. Through the relay clamping and flipping method, the visual camera 21 realizes all-round and no-dead-angle detection of the acrylic plate, can accurately identify minor flaws and potential internal defects, strictly control product quality, and effectively improve production efficiency.

[0064] like Fig.11 As shown, the present invention also discloses a visual inspection method for acrylic plate repair, which specifically comprises the following steps: Place the acrylic sheet on the placement seat 31. When the conveying device 3 is in operation, the acrylic sheet will be driven to the bottom of the shelf 2. The conveying device 3 will then stop transmitting. The visual camera 21 will detect the acrylic sheet. The light inspection mechanism 6 will provide a light source. The propulsion device 531 will start to operate, driving the clamping mechanism 55 at one end to approach one side of the acrylic sheet. The electric rod 534 will start to make the clamping mechanism 55 clamp one side of the acrylic sheet.

[0065] Next, the motor 1 511 is started, driving the propulsion device 1 531 and the propulsion device 2 541 to rise synchronously. When the propulsion device 1 531 rises, the rack 523 descends and contacts the first spur gear 533, causing the first spur gear 533 to rotate, driving the clamped acrylic plate to flip, so that the visual camera 21 detects the flipped side.

[0066] When the propulsion device 1 531 rises, it drives the "U"-shaped tooth plate 563 to mesh with the gear 3 562 to rotate, and drives the bevel gear 1 564 and the bevel gear 2 565 to rotate, so that the rotating rod 566 drives the second helical gear 567 to rotate. When the other clamping mechanism 55 extends, the first helical gear 544 meshes with the second helical gear 567, and the first helical gear 544 rotates, driving the screw rod 545 to rotate, and then the two clamping blocks 554 are clamped on the other side of the acrylic plate.

[0067] After the clamping is completed, the propulsion device 1 531 is retracted. The motor 1 511 is reversed, and the retracted propulsion device 1 531 drives the tooth block on the other side of the "U"-shaped tooth plate 563 to mesh with the gear 3 562. When the propulsion device 2 541 descends, the "U"-shaped tooth plate 563 falls and drives the gear 3 562 to rotate, and the second spur gear 542 meshes with the rack 523, and the clamping mechanism 55 on the other side of the clamping drives the acrylic plate to flip, and then the propulsion device 2 541 continues to drive the first helical gear 544 to mesh with the second helical gear 567 to rotate, so that the clamping mechanism 55 loosens the acrylic plate.

[0068] The acrylic plate slowly falls onto the placement seat 31, and the inspected acrylic plate is conveyed by the conveying device 3. When the defective acrylic plate passes under the marking device 8, the visual camera 21 transmits the detected defect information to the control terminal, and the control terminal starts the marking device 8 to mark the defective acrylic plate.

[0069] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, i.e., they may be located in one place, or they may be distributed on multiple network units.

10. A visual inspection method for acrylic plate repair, using a visual inspection system for acrylic plate repair as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: The acrylic plate is placed on the placement seat (31). When the transmission device (3) is in operation, the acrylic plate is driven to be transmitted to the bottom of the rack (2). The transmission device (3) then stops transmitting. The visual camera (21) detects the acrylic plate. The light inspection mechanism (6) provides a light source. The propulsion device (531) starts to operate, driving the clamping mechanism (55) at one end to approach one side of the acrylic plate. The electric rod (534) is started, so that the clamping mechanism (55) clamps one side of the acrylic plate. Next, the motor 1 (511) is started, driving the propulsion device 1 (531) and the propulsion device 2 (541) to rise synchronously. When the propulsion device 1 (531) rises, the rack (523) descends and contacts the first spur gear (533), causing the first spur gear (533) to rotate, driving the clamped acrylic plate to flip, so that the visual camera (21) detects the flipped side; When the propulsion device 1 (531) rises, it drives the "U"-shaped tooth plate (563) to mesh with the gear 3 (562) to rotate, and drives the bevel gear 1 (564) and the bevel gear 2 (565) to rotate, so that the rotating rod (566) drives the second helical gear (567) to rotate. When the other clamping mechanism (55) extends, the first helical gear (544) meshes with the second helical gear (567), and the first helical gear (544) rotates, driving the screw rod (545) to rotate, and then the two clamping blocks (554) are clamped on the other side of the acrylic plate; After the clamping is completed, the propulsion device 1 (531) is retracted, and the motor 1 (511) is reversed. The retracted propulsion device 1 (531) drives the tooth block on the other side of the "U"-shaped tooth plate (563) to mesh with the gear 3 (562). When the propulsion device 2 (541) descends, the "U"-shaped tooth plate (563) falls and drives the gear 3 (562) to rotate. The second spur gear (542) meshes with the rack (523), and the clamping mechanism (55) on the other side of the clamp drives the acrylic plate to flip. Then, the propulsion device 2 (541) continues to drive the first helical gear (544) to mesh with the second helical gear (567) to rotate, so that the clamping mechanism (55) loosens the acrylic plate. The acrylic plate slowly falls onto the placement seat (31), and the inspected acrylic plate is conveyed by the conveying device (3). When the acrylic plate with defects passes under the marking device (8), the visual camera (21) transmits the detected defect information to the control terminal, and the control terminal activates the marking device (8) to mark the acrylic plate with defects.
