Technical Field
[0001] This utility model relates to the field of AOI inspection technology, specifically to an AOI inspection device. Background Technology
[0002] In fields such as electronic manufacturing, semiconductor packaging, and precision instrument assembly, as products develop towards miniaturization and high density, the requirements for detecting product surface defects, welding quality, and component assembly accuracy are becoming increasingly stringent. Automated optical inspection (AOI) equipment, as a key device to replace manual inspection, has become a core link in modern industrial production to ensure product quality and improve production efficiency due to its advantages of high speed, high precision, and non-contact inspection. However, existing AOI inspection equipment still has certain shortcomings in its use. For example, the image acquisition device for an AOI (Automated Optical Inspection) device proposed in application number CN201721556111.6 is installed on the AOI inspection device and connected to a computer on the AOI inspection device. The image acquisition device includes: a mounting bracket, a camera, a camera mounting base, a light source, and a light source mounting base. The mounting bracket is rectangular, with its first end mounted on the AOI inspection device and its second end perpendicularly connected to one end of the light source mounting base. The light source is mounted on the light source mounting base. The camera mounting base is L-shaped. The first end of the camera mounting base is mounted on the mounting bracket, and the second end of the camera mounting base has a rectangular groove for mounting the camera. The camera is snapped into the rectangular groove. The light source mounting base and the bottom center of the light source both have clearance holes for the camera to take pictures, and the lens of the camera is coaxially arranged with the clearance holes. In actual use, the image acquisition device uses a fixed mounting bracket, and the camera and the light source are only fixed by a rigid structure, lacking a dynamic adjustment transmission design. This makes it impossible to make real-time and precise displacement adjustments with changes in the position of the workpiece, and the imaging accuracy is easily affected by relative position deviations.
[0003] Therefore, we propose an AOI inspection device to address the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide an AOI inspection device to solve the problems mentioned in the background art, which are that the fixed mounting brackets, cameras and light sources are fixed by rigid structures and lack dynamic adjustment transmission design, making it impossible to make real-time precise displacement adjustments according to changes in the workpiece position, and the imaging accuracy is easily affected by relative position deviations.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an AOI inspection device, comprising a device body, an operation panel installed on the top front end of the device body, cooling fan assemblies installed on both sides of the bottom rear end of the device body, a flip cover connected to the top of the device body via a hinge, a cylinder connected between the flip cover and the device body, and a safety door sensor installed on the top left side inside the device body. An X-axis axial transmission mechanism is installed on the rear side of the main body of the equipment. A limit groove is installed on the top of the X-axis axial transmission mechanism. A drag chain is installed inside the limit groove. A connecting plate is connected to the top of the drag chain. An AOI detection head is installed on the front side of the X-axis axial transmission mechanism. An axial transmission mechanism along the Y-axis is installed on the bottom side of the main body of the equipment, and a positioning fixture assembly is installed on the top of the axial transmission mechanism along the Y-axis.
[0006] Preferably, the axial transmission mechanism includes a mounting base fixedly installed on the inner rear side and inner bottom side of the main body of the equipment. In the Y-axis axial transmission mechanism, a protective plate is fixedly installed on the top of the mounting base. Tracks are symmetrically installed inside the mounting base. A first fixed base is fixedly installed on the right end of the mounting base. A servo motor is fixedly installed on the back of the first fixed base. A drive pulley is fixedly installed on the shaft end of the servo motor. A second fixed base is fixedly installed on the left end of the mounting base. A driven pulley is rotatably installed inside the second fixed base. A synchronous belt is fitted around the outer rings of the driven pulley and the drive pulley. A movable seat is fixedly installed on the synchronous belt.
[0007] With the above-mentioned structure, the axial transmission mechanism drives the active pulley to rotate via a servo motor, which in turn drives the synchronous belt transmission via the driven pulley. This enables precise power transmission. The high-precision control of the servo motor ensures the positional accuracy of the transmission process. The symmetrically arranged tracks and slides provide stable guidance for the moving parts, reducing swaying and offset during transmission, improving overall transmission smoothness, and thus ensuring the accuracy requirements of AOI inspection.
[0008] Preferably, the axial transmission mechanism includes a positioning seat fixedly installed on the inner rear side and inner bottom side of the main body of the equipment. In the Y-axis axial transmission mechanism, a protective plate is fixedly installed on the top of the positioning seat. Tracks are symmetrically installed inside the positioning seat. Sleeves are fixedly connected to both ends of the track. A lead screw is rotatably installed inside the sleeve. A first pulley is fixedly connected to one end of the lead screw. A servo motor is fixedly installed on the back of the right end of the positioning seat. A second pulley is fixedly installed on the shaft end of the servo motor. A transmission belt is fitted around the outer rings of the first pulley and the second pulley. A movable seat is fitted around the outer ring of the lead screw.
[0009] The above-described structure provides stable support for components such as the track and lead screw to enhance structural rigidity. The track is fixed by a sleeve, which guides the movable seat and restricts the axial displacement of the lead screw, reducing deformation and ensuring smooth transmission. The servo motor drives the lead screw to rotate via the second pulley, transmission belt, and first pulley. The helical engagement between the lead screw and the movable seat converts the rotational motion into linear motion, improving positioning accuracy and ensuring good repeatability. Its self-locking characteristic prevents the movable seat from shifting due to external forces, making it suitable for supporting fixtures to prevent workpiece displacement.
[0010] Preferably, the axial transmission mechanism further includes a slide mounted off-center on the surface of the movable seat, the slide being slidably connected to the track.
[0011] With the above-mentioned structural design, the slide is installed inside the movable seat in a staggered manner and is slidably connected to the track. This not only ensures that the movable seat slides stably along the track, but also disperses the force during the movement through the staggered structure, reducing wear on a single part, extending the service life of the transmission mechanism, reducing the probability of movement jamming, and improving the smoothness of equipment operation.
[0012] Preferably, in the axial transmission mechanism along the X-axis, the front end of the slide is fixedly connected to the AOI detection head, and the top end of the mounting base in the axial transmission mechanism along the X-axis is fixedly connected to the connecting plate.
[0013] With the above-mentioned structural design, the slide in the X-axis transmission mechanism is directly connected to the AOI detection head, so that the X-axis movement of the slide can directly drive the detection head to move synchronously, ensuring the positioning accuracy of the detection head in the X direction and ensuring accurate coverage of the detection range. The mounting base and the connecting plate are fixed, so that the cable chain remains fixed with the mounting base. The top of the cable chain is connected to the relevant components of the slide, and can extend and retract with the movement of the slide, effectively protecting the internal cables from being pulled and worn, avoiding cable failures from affecting equipment operation, and improving the stability and service life of the equipment.
[0014] Preferably, the positioning fixture assembly includes a connecting seat fixedly installed on the top of the slide in the axial transmission mechanism along the Y-axis. A front support plate is fixedly installed on the top surface of the front end of the connecting seat. A connecting member is fixedly connected to the rear side of the front support plate. A rear support plate is fixedly installed at the rear end of the connecting member. A rear limiting seat is fixedly installed on the top surface of the rear support plate. A receiving seat is fixedly installed on the top surface of the front support plate.
[0015] Preferably, the positioning fixture assembly further includes shaft seats fixedly installed at both ends of the top surface of the front support plate. A rotating rod is rotatably installed inside the shaft seat. A reset seat is fixedly sleeved on the outer ring of both ends of the rotating rod. A spring is connected between the bottom front end of the reset seat and the front support plate. A gripper is installed on the outer ring of the rotating rod. Three sets of grippers are provided. A linkage seat is fixedly sleeved on the outer ring of the left end of the rotating rod. A roller is rotatably installed on the bottom end of the linkage seat. A blocking seat is attached to the bottom of the roller. The bottom surface of the blocking seat is fixedly connected to the main body of the equipment.
[0016] With the above-mentioned structural design, the front support plate and the rear support plate cooperate to form a workpiece support surface, which can stably support the workpiece to be inspected. The rear limit seat and the receiving seat can initially limit the placement position of the workpiece, ensuring that the placement benchmark of different workpieces is consistent during inspection, reducing the inspection error caused by workpiece placement deviation, and providing a basic guarantee for subsequent accurate inspection. The positioning fixture assembly achieves automatic clamping and releasing of workpieces through mechanical linkage. When the Y-axis transmission mechanism drives the fixture forward, the roller contacts and is blocked by the blocking seat, causing the linkage seat to drive the rotating rod to rotate, which in turn causes the gripper to rotate and release for easy workpiece loading and unloading. When the fixture moves backward, the roller disengages from the blocking seat, the spring pulls the reset seat to reset the rotating rod, and the gripper automatically clamps the workpiece. No additional power source is required, simplifying the structure while achieving automated clamping. The three sets of grippers are distributed at multiple points, which can clamp the workpiece from different positions to ensure that the workpiece does not shift or shake during the inspection process, further improving the inspection accuracy and reliability.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the AOI inspection equipment; 1. The synchronous belt drive axial mechanism, with the control of a servo motor and the coordinated transmission of the driving and driven pulleys, realizes the transmission of power. The sliding cooperation between the symmetrical track and the slide reduces transmission sway and ensures the basic positioning effect. The lead screw driven axial mechanism uses a positioning seat to enhance structural rigidity, a sleeve to limit lead screw deformation, and a self-locking feature to prevent displacement caused by external forces, making it suitable for the load-bearing requirements of fixtures. Meanwhile, the staggered installation of the slide blocks can distribute the dynamic force, reduce wear on a single part to extend the service life, and the drag chain extends and retracts with the slide blocks to protect the cable, effectively reducing the risk of cable failure and providing dual protection for the long-term stable operation of the equipment and the accuracy of AOI detection. 2. The front and rear support plates form a stable support surface, and the rear limit seat and the receiving seat unify the workpiece placement benchmark, reducing detection errors caused by placement deviations from the source. The automatic clamping function achieved through mechanical linkage requires no additional power source. It only relies on the Y-axis transmission to drive the roller to contact or disengage from the blocking seat, which triggers the rotation of the rotating rod and the spring reset, controlling the opening and closing of the gripper. This simplifies the structure and improves the efficiency of workpiece loading and unloading. The multi-point distribution design of the three sets of grippers can firmly fix the workpiece from different positions, avoiding displacement or shaking during the detection process, further ensuring the reliability of the detection results and adapting to the detection needs of diverse workpieces.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: Please refer to Figure 1-7 This utility model provides a technical solution: an AOI detection device, including a device body 1, an operation panel 2 installed on the top front end of the device body 1, cooling fan groups 3 installed on both sides of the bottom rear end of the device body 1, a flip cover 4 connected to the top of the device body 1 by a hinge, a cylinder 5 connected between the flip cover 4 and the device body 1, and a safety door sensor 6 installed on the top left side inside the device body 1. In the above structural design, the main body 1 of the equipment serves as the overall support frame, providing the installation foundation and operating space for each component. The operation panel 2 serves as the core of human-machine interaction, allowing operators to set detection parameters, start or stop the equipment, and view the operating status, thereby realizing command control of the equipment. The cooling fan group 3 starts when the equipment is running, and through the airflow circulation on both sides of the bottom rear end, it promptly dissipates the heat generated inside the equipment by the operation of electronic components and transmission mechanisms, avoiding excessive temperature from affecting the performance stability of the components. The flip cover 4 can rotate around the top of the main body 1 via a hinge. Its opening and closing action is driven by a cylinder 5. When it is necessary to pick up or put down a workpiece or perform maintenance, the piston rod of the cylinder 5 extends or retracts to open the flip cover 4. After the operation is completed, the cylinder 5 resets to close the flip cover 4, realizing the sealing and opening of the internal space of the equipment. The safety door sensor 6 detects the closing status of the flip cover 4 in real time. When the flip cover 4 is not fully closed, the sensor sends a signal to the equipment control system to prohibit the equipment from starting or trigger an emergency stop, preventing personnel from contacting the internal moving parts during operation and causing safety accidents, thus ensuring operational safety. All components work together to realize the human-machine interaction, safety protection, heat dissipation, and space opening and closing functions of the equipment, providing basic operating conditions for subsequent testing processes.
[0022] An X-axis axial transmission mechanism is installed on the rear side of the inner side of the main body 1. A limit groove 19 is installed on the top of the X-axis axial transmission mechanism, and a drag chain 18 is installed inside the limit groove 19. A connecting plate 17 is connected to the top of the drag chain 18. An AOI inspection head 20 is installed on the front side of the X-axis axial transmission mechanism. An Y-axis axial transmission mechanism is installed on the bottom side of the inner side of the main body 1. The axial transmission mechanism includes a mounting base 7 fixedly installed on the rear side and bottom side of the inner side of the main body 1. A protective plate 21 is fixedly installed on the top of the mounting base 7 in the Y-axis axial transmission mechanism. Tracks 8 are symmetrically installed inside the mounting base 7. A first fixed base 9 is fixedly installed on the right end of the mounting base 7. A servo motor 10 is fixedly mounted on the back of the mounting base 9. A drive pulley 11 is fixedly mounted on the shaft end of the servo motor 10. A second fixed base 12 is fixedly mounted on the left end of the mounting base 7. A driven pulley 13 is rotatably mounted inside the second fixed base 12. A synchronous belt 14 is fitted around the outer ring of the driven pulley 13 and the drive pulley 11. A movable base 15 is fixedly mounted on the synchronous belt 14. The axial transmission mechanism also includes a slide 16 that is offset from the surface of the movable base 15. The slide 16 is slidably connected to the track 8. In the axial transmission mechanism of the X-axis, the front end of the slide 16 is fixedly connected to the AOI detection head 20. In the axial transmission mechanism of the X-axis, the top end of the mounting base 7 is fixedly connected to the connecting plate 17. The above structure is designed so that the equipment realizes the relative movement between the AOI inspection head 20 and the workpiece to be inspected through two sets of identical axial transmission mechanisms in the X-axis and Y-axis directions, providing a basis for full-area inspection. The guard plate 21 is fixed to the top of the mounting base 7 of the Y-axis transmission mechanism. Its function is to shield the internal structure of the fixture, avoid interference or collision from external debris, and form a protective barrier. The power transmission process of the axial transmission mechanism is as follows: After the servo motor 10 starts, the active pulley 11 at its shaft end rotates, which drives the driven pulley 13 to rotate synchronously through the meshing synchronous belt 14, so that the synchronous belt 14 performs linear transmission along the length of the mounting base 7. Since the movable base 15 is fixed on the synchronous belt 14, the movement of the synchronous belt 14 drives the movable base 15 to move synchronously. The slide 16 installed inside the movable base 15 is misaligned and slides with the symmetrical track 8 on the mounting base 7, providing stable guidance for the movement of the movable base 15, ensuring that there is no deviation or jamming during the movement process, and achieving high-precision linear displacement. Specifically, regarding the X-axis transmission mechanism: the front end of its slide 16 is fixedly connected to the AOI detection head 20. Therefore, the X-axis movement of the slide 16 directly drives the AOI detection head 20 to move along the X-axis, realizing the horizontal adjustment of the detection head's position. At the same time, the top of the X-axis mounting base 7 is connected to the cable chain 18 through the connecting plate 17. The cable chain 18 is placed in the limiting groove 19. When the detection head moves with the slide 16, the cable chain 18 can adaptably extend and retract, playing a role in storing and protecting the cable of the detection head, avoiding cable pulling or wear. The limiting groove 19 restricts the movement trajectory of the cable chain 18, ensuring its stable operation. The Y-axis transmission mechanism uses the same transmission principle to drive the positioning fixture assembly at its top to move along the Y-axis, cooperating with the AOI inspection head 20 in the X-axis to form a complete motion coverage in the plane, ensuring that the inspection head can accurately inspect all areas of the workpiece.
[0023] A positioning fixture assembly is mounted on the top of the Y-axis axial transmission mechanism. The positioning fixture assembly includes a connecting seat 22 fixedly mounted on the top of the slide 16 in the Y-axis axial transmission mechanism. A front support plate 23 is fixedly mounted on the front top surface of the connecting seat 22. A connecting member 24 is fixedly connected to the rear side of the front support plate 23. A rear support plate 25 is fixedly mounted on the rear end of the connecting member 24. A rear limit seat 26 is fixedly mounted on the top surface of the rear support plate 25. A receiving seat 27 is fixedly mounted on the top surface of the front support plate 23. The positioning fixture assembly also includes a connecting seat 26 fixedly mounted on the front support plate 23. The top surface of the support plate 23 has two bearing seats 28 at both ends. A rotating rod 29 is rotatably installed inside the bearing seat 28. A reset seat 30 is fixedly sleeved on the outer ring of both ends of the rotating rod 29. A spring 31 is connected between the bottom front end of the reset seat 30 and the front support plate 23. A gripper 32 is installed on the outer ring of the rotating rod 29. Three sets of grippers 32 are provided. A linkage seat 33 is fixedly sleeved on the outer ring of the left end of the rotating rod 29. A roller 34 is rotatably installed on the bottom end of the linkage seat 33. A blocking seat 35 is attached to the bottom of the roller 34. The bottom surface of the blocking seat 35 is fixedly connected to the main body of the equipment 1. In the above structure design, the connecting seat 22 is fixedly connected to the slide 16 of the Y-axis transmission mechanism. When the Y-axis servo motor 10 drives the slide 16 to move in the Y direction along the track 8, the connecting seat 22 will synchronously drive the front support plate 23, the connecting piece 24, the rear support plate 25 and all the workpiece positioning components above to move as a whole along the Y-axis direction, realizing the "follow-up displacement" of the fixture and the workpiece, providing a moving basis for subsequent inspection position adjustment or workpiece picking and placing; The front support plate 23 and the rear support plate 25 form the workpiece bearing plane. The rear limit seat 26 and the receiving seat 27 respectively limit the workpiece placement reference from the front and rear directions to ensure that the workpiece is placed in a uniform position. The bearing seats 28 at both ends of the front support plate 23 support the rotation of the rotating rod 29. The three sets of grippers 32 on the rotating rod 29 are used to clamp the workpiece. Their tightness is controlled by mechanical linkage: when the fixture moves forward with the Y-axis transmission, the roller 34 at the bottom of the linkage seat 33 at the left end of the rotating rod 29 contacts and is blocked by the fixed blocking seat 35, pushing the linkage seat 33 to drive the rotating rod 29 to rotate, causing the reset seat 30 to compress the spring 31, and the grippers 32 to open accordingly. When the fixture moves backward to the detection position, the roller 34 disengages from the blocking seat 35, the spring 31 resets and pushes the rotating rod 29 to rotate in the opposite direction, and the grippers 32 tighten to clamp the workpiece at multiple points, ensuring that the workpiece is stable and has no displacement during the detection process. Finally, it cooperates with the X-axis AOI detection head 20 to complete the accurate detection.
[0024] Example 2: Based on Example 1, this utility model adopts the following... Figure 8 The technical solution shown further discloses that the axial transmission mechanism includes a positioning seat 36 fixedly installed on the inner rear side and inner bottom side of the main body 1. In the axial transmission mechanism of the Y axis, a guard plate 21 is fixedly installed on the top of the positioning seat 36. Tracks 8 are symmetrically installed inside the positioning seat 36. Sleeves 37 are fixedly connected to both ends of the track 8. A lead screw 38 is rotatably installed inside the sleeve 37. A first pulley 39 is fixedly connected to one end of the lead screw 38. A servo motor 10 is fixedly installed on the back of the right end of the positioning seat 36. A second pulley 40 is fixedly installed on the shaft end of the servo motor 10. A transmission belt 41 is meshed on the outer ring of the first pulley 39 and the second pulley 40. A movable seat 15 is sleeved on the outer ring of the lead screw 38. In the above structure design, the positioning seat 36 serves as the core mounting carrier, and is fixed to the inner rear side (corresponding to the X-axis) and inner bottom side (corresponding to the Y-axis) of the main body 1 respectively. The top of the positioning seat 36 of the Y-axis transmission mechanism is also fixed with a protective plate 21, which can protect the fixture components below. The symmetrically installed tracks 8 inside the positioning seat 36 are fixed by the sleeves 37 at both ends. The sleeves 37 also support the lead screw 38, allowing the lead screw 38 to rotate stably inside. When the equipment is started, the servo motor 10 on the right side of the positioning seat 36 outputs power to drive the second pulley 40 at its shaft end to rotate. The second pulley 40 drives the first pulley 39 at one end of the lead screw 38 to rotate synchronously through the transmission belt 41 meshing with the outer ring, thereby driving the lead screw 38 to rotate around its own axis. Since the movable seat 15 is sleeved on the outer ring of the lead screw 38 and forms a helical engagement with the lead screw 38, the rotational motion of the lead screw 38 is converted into linear motion of the movable seat 15 along the length direction of the lead screw 38. At the same time, the movable seat 15 forms a sliding engagement with the track 8 inside the positioning seat 36. The track 8 provides stable guidance for the linear motion of the movable seat 15, preventing it from deviating or shaking during movement. Finally, the movable seat 15 drives the corresponding load (AOI detection head in the X-axis and positioning fixture assembly in the Y-axis) to move precisely.
