[0026] Drive mechanism 201: As part of the material conveying assembly 20, the drive mechanism 201 is responsible for driving the support member 202 to move along the Y-axis direction, thereby realizing the conveying of materials in the front and back directions.
[0027] Support component 202: This component is driven by the drive mechanism 201 and is used to support the material platform 203 and the fixed frame 204, and moves in the Y-axis direction to deliver the material to different positions.
[0028] Material Platform 203: This platform is used for lifting and adjustment. When rising, it rests against the bottom of the chip or material. Its design typically takes into account the size, shape, and weight of the material. It detaches during transport and remains firmly against the material during inspection to ensure smooth material transport and stability during the inspection process.
[0029] Fixed frame 204: This frame structure is used to limit the lifting and lowering of the material platform 203 and to provide an installation base for the pressing mechanism 205 and the clamping and conveying mechanism 206. The material platform 203 moves up and down inside the fixed frame 204.
[0030] Pressing mechanism 205: This mechanism is used to apply pressure to the material placed on the material platform 203 to ensure that the material maintains a stable position during the testing process and prevents shaking or displacement.
[0031] Material clamping and conveying mechanism 206: This mechanism is responsible for clamping and conveying materials, and usually plays a role when materials are fed, after inspection, and when they need to be transferred to the next process or unloaded.

[0033] Optical Inspection Component 40: This component is the core inspection unit of the equipment, and typically includes a light source, optical lens, image sensor, etc., used for high-precision image acquisition and defect analysis of the material to be inspected.
[0034] Specifically, the support assembly 10 is the basic frame of the equipment, providing overall stability and load-bearing capacity. As one implementation, the support assembly 10 can be constructed of welded steel or cast aluminum alloy to ensure its rigidity and vibration resistance during equipment operation. The support assembly 10 internally includes a base 101, which is the main mounting platform of the equipment. Its surface is precision-machined to ensure the flatness of the installed components. A first drive 102 is configured on one side of the base 101. This first drive 102 is responsible for driving the relevant components to move linearly along the X-axis. For example, the first drive 102 can be a ball screw mechanism driven by a stepper motor or a pneumatic push rod, used to push the material conveying assembly 20 to move in the X-axis direction.
[0035] A material conveying assembly 20 is configured on the other side of the base 101. The main function of this material conveying assembly 20 is to achieve precise conveying and positioning of the material to be tested within the equipment. The material conveying assembly 20 can take various forms; for example, it can be a synchronous belt drive system driven by a servo motor, or a slide table driven by a cylinder, for moving the material in the Y-axis direction. The material conveying assembly 20 includes a drive mechanism 201 that conveys along the Y-axis. The drive mechanism 201 can be, for example, a linear motor, or a motor driven by a rack and pinion system, with its output end connected to a support member 202. The support member 202 is a structure that carries the material; it can be a simple flat plate or a tray with a specific shape for movement in the Y-axis direction.
[0036] On the side of the support member 202 opposite to the drive mechanism 201, there are a material platform 203 and a fixing frame 204. The material platform 203 is used to place the material to be tested, and its surface can be designed as a flat loading surface or have grooves for positioning the material. The fixing frame 204 is a frame structure, and the material platform 203 is configured to move up and down inside the fixing frame 204, and the material passes through the material platform 203 during the conveying process. Limiting grooves are opened on the opposite end faces of the material platforms 203 on both sides for the chip to slide through, and it is ensured that the chip is in clearance fit with the limiting groove during the sliding conveying process without leaving scratches on the chip.
[0037] A pressing mechanism 205 is configured on the outer side of the fixing frame 204. The function of the pressing mechanism 205 is to apply pressure to the material placed on the material platform 203 to ensure that the material maintains a stable position during the testing process. The pressing mechanism 205 can be a simple gravity block or a pressing head driven by a small cylinder, which fixes the material on the material platform 203 by moving downward.
[0038] A clamping and conveying mechanism 206 is provided on the side of the fixed frame 204 away from the drive mechanism 201. The clamping and conveying mechanism 206 is used to complete the feeding and delivery of materials on the material platform 203 before and after material detection.
[0039] A side mounting plate 30 is disposed on the other side of the base 101. The side mounting plate 30 provides a stable mounting reference for the optical inspection assembly 40. The side mounting plate 30 can be a metal plate perpendicular to the base 101 and fixed to the base 101 by bolts. The optical inspection assembly 40 is disposed on the side of the side mounting plate 30 closest to the material conveying assembly 20. The optical inspection assembly 40 is the core functional unit of the equipment and is used for image acquisition and analysis of the material to be inspected. For example, the optical inspection assembly 40 may include an industrial camera and a ring light source for acquiring high-resolution images of the material surface.
[0040] Specifically, the optical inspection component 40 uses a 25-megapixel camera with automatic focusing along the Z-axis as its light source module, and can be equipped with a higher resolution camera, an automatic adjustment system, and a high-brightness coaxial light source. For example, four sets of green collimated light sources and two sets of red collimated light sources expose defects in different layers through different lighting methods, and the accompanying image processing algorithm matches and calculates to distinguish defects on different surfaces.
[0041] The above technical solution will be explained in more detail below through a more specific embodiment: If a production line requires fully automated optical inspection of chips to identify surface defects, then...
[0042] First, the electronic components to be tested are sent to the equipment inlet via an external conveying system. The first drive 102 pushes the material conveying assembly 20 to the equipment inlet in the X-axis direction. Then, the clamping conveying mechanism 206 clamps the chip to be tested and conveys it onto the material conveying assembly 20. During the material loading process, the chip is conveyed and pressed by the cooperation of the pressing mechanism 205 and the support member 202. Then, the first drive 102 is run again, driving the material conveying assembly 20 to move to the detection position.
[0043] When the support member 202 reaches the loading position, the material platform 203 is in a low position to receive the detection chip. The chip is clamped and transported from the inlet to the material platform 203 by the clamping and conveying mechanism 206. Then, the material platform 203 moves upward under the action of the support member 202, and works with the pressing mechanism 205 to press the chip.
[0044] The drive mechanism 201 drives the support component 202 to move along the Y-axis, making precise adjustments and moving it below the optical inspection component 40, which inspects the surface of the chip. After the inspection is completed, the clamping and conveying mechanism 206 clamps the chip again, the pressing mechanism 205 releases the pressure on the chip, the material platform 203 descends and detaches from the chip, and the chip is transported to the equipment outlet by the clamping and conveying mechanism 206.
[0045] This technical solution provides a highly efficient and high-precision fully automated optical inspection solution through its ingenious mechanical structure and motion control design. It overcomes the shortcomings of existing technologies in terms of material positioning stability, detection accuracy, and automation level, and provides more reliable technical support for quality control in industrial production.
[0046] In actual operation, relying solely on the output end of the drive mechanism 201 to connect the support member 202 for Y-axis conveying may result in insufficient stability and low positioning accuracy of the support member 202 during movement. This is especially true under high-speed or heavy-load conditions, where it is prone to shaking or deviation, thereby affecting the accuracy of material conveying and the precision of subsequent optical inspection.
[0047] In this regard, this application further proposes that the drive mechanism 201 includes an outer frame 2011 disposed on one side of the base 101, a second drive 2012 disposed inside the outer frame 2011, the output end of the second drive 2012 being connected to the support member 202, and a positioning shaft 2013 disposed on the side of the outer frame 2011 near the support member 202.
[0048] It should be noted that the outer frame 2011 can be a metal structure with sufficient strength and rigidity, such as aluminum alloy profiles, welded steel plates, or castings, to withstand the operating load of the internal drive components and the motion reaction force of the support member 202. It can be securely mounted directly to the output end of the first drive 102 via bolts, welding, or other fixing methods. The second drive 2012 is the core power source for achieving precise movement of the support member 202 along the Y-axis. It receives control signals and converts electrical energy or other forms of energy into mechanical motion, thereby driving the support member 202 to a predetermined displacement. The second drive 2012 can take various forms; for example, it can be a stepper motor or servo motor, driving the support member 202 to move via a transmission mechanism such as a rack and pinion, ball screw, or synchronous belt. Alternatively, it can be a cylinder or hydraulic cylinder, pushing the support member 202 through the extension and retraction of a piston rod. The main function of the positioning shaft 2013 is to provide guidance and limitation for the support component 202, ensuring that the support component 202 maintains a stable posture when moving linearly along the Y-axis under the drive of the second drive 2012, preventing deflection or wobbling, thereby improving the accuracy and stability of the movement. The positioning shaft 2013 can be one or more precision-machined linear guides, such as cylindrical guides, square guides, or V-shaped guides, with surfaces hardened to improve wear resistance. The support component 202 will be equipped with corresponding guide sleeves or sliders, which cooperate with the positioning shaft 2013 to achieve low-friction linear motion.
[0049] In one specific implementation, the drive mechanism 201 may include an outer frame 2011 constructed from aluminum alloy profiles, which is bolted to the output end of the first drive 102. Inside the outer frame 2011, a hydraulic cylinder can be installed as a second drive 2012, the output shaft of which is connected to the support member 202. When the second drive 2012 operates, it drives the support member 202 to move along the Y-axis. The positioning shaft 2013 ensures that the support member 202 maintains a smooth and precise straight trajectory during movement, avoiding any lateral or rotational deviations.
[0050] In practical operation, achieving stable and precise lifting of the material platform 203, and ensuring its positioning accuracy during the lifting process, is crucial for subsequent operations such as material pressing and optical inspection. If the lifting control of the material platform 203 is not precise or lacks stability, it may affect the accurate placement of materials and the inspection results.
[0051] In this regard, this application further proposes that the support member 202 includes a support plate 2021 disposed at the output end of the second drive 2012 and movable at the upper limit of the positioning shaft 2013. The support plate 2021 is provided with multiple sets of reset parts 2022 and a third drive 2023 on the side away from the base 101. The output end of the third drive 2023 is connected to the lifting member 2024.
[0052] The support plate 2021, as a component of the support member 202, primarily functions to provide a stable bearing surface for mounting the material platform 203, the reset unit 2022, and the third drive 2023. The support plate 2021 can be made of materials with sufficient rigidity and strength, such as aluminum alloy, stainless steel, or high-strength engineering plastics. Its structural design can be flat or integrated with reinforcing ribs according to actual needs to ensure stability during movement and load-bearing processes. The support plate 2021 connects to the output end of the second drive 2012 and cooperates with the positioning shaft 2013, thereby achieving limited movement in the Y-axis direction, ensuring smooth material conveying and positioning accuracy. The reset unit 2022 provides a downward reset force or elastic support to the material platform 203 under specific working conditions. Its implementation can be varied; for example, it can employ a set of elastic elements, such as helical springs, disc springs, or gas springs, to provide the reset force through their own elastic deformation.
[0053] Specifically, the reset unit 2022 in this application may include a hollow sleeve disposed on one side of the support plate 2021, and an elastic rod connected by a spring is provided inside the hollow sleeve. The reset unit 2022 provides an efficient and reliable reset mechanism for the material platform 203. This design ensures that the material platform 203 can accurately and stably return to the preset initial position after completing the lifting operation.
[0054] The third drive 2023 is the core power source for the vertical lifting of the material platform 203. This drive device can take various forms; for example, it can be a stepper motor or a servo motor, converting the motor's rotational motion into the linear lifting motion of the lifting component 2024 via a lead screw, rack and pinion, or linkage mechanism. Alternatively, a cylinder or hydraulic cylinder can be used, directly driving the lifting component 2024 for precise linear displacement by controlling fluid pressure. The selection of the third drive 2023 should consider the required lifting speed, accuracy, and load-bearing capacity. The lifting component 2024 is the actuator that directly contacts the material platform 203 and is driven by the third drive 2023 to achieve the vertical lifting of the material platform 203.
[0055] It should be noted that this application further proposes that the lifting component 2024 includes an outer shell that is limited and movable on the fixed frame 204. The side of the outer shell near the guide rod 2032 is provided with an inclined end face, and the side of the guide rod 2032 near the outer shell is provided with a chamfer. The inclined end face of the outer shell of the lifting component 2024 and the chamfer of the guide rod 2032 cooperate with each other, providing effective guidance and calibration during the lifting and lowering of the material platform 2031. This significantly reduces the risk of jamming or collision between the guide rod 2032 and the outer shell, ensuring the smoothness and stability of the movement of the material platform 2031. At the same time, this design improves the vertical positioning accuracy of the material platform 203, reduces the problem of inaccurate material position caused by mechanical deviation, thereby improving the overall operating efficiency and reliability of the detection results of the fully automatic optical inspection equipment.
[0056] The solution of this application is achieved in the following way: In the above-mentioned fully automatic optical inspection equipment, the material conveying component 20 is conveyed along the Y-axis by the drive mechanism 201, wherein the output end of the second drive 2012 is connected to the support member 202. In order to achieve precise vertical positioning of the material platform 203 within the fixed frame 204, the support member 202 further includes a support plate 2021. The support plate 2021 is not only connected to the output end of the second drive 2012, thereby moving along the Y-axis with the second drive 2012, but also ensures the smoothness and accuracy of the movement in the Y-axis direction by cooperating with the limiting movement of the positioning shaft 2013. On the side of the support plate 2021 away from the base 101, multiple sets of reset parts 2022 and a third drive 2023 are provided. The output end of the third drive 2023 is connected to the lifting member 2024. When it is necessary to adjust the vertical height of the material platform 203, the third drive 2023 is activated, driving the lifting member 2024 to move along the X-axis. The lifting component 2024 acts directly on the material platform 203, enabling precise lifting and lowering within the fixed frame 204. Simultaneously, the reset component 2022 provides auxiliary reset force or support when the third drive 2023 is not operating or moving downwards, ensuring the material platform 203 can stably return to its preset position or remain stable at a specific height. Through this structure, the material platform 203 can not only move as a whole along the Y-axis with the support component 202, but also achieve independent, high-precision vertical lifting and lowering within itself. This provides precise material positioning and height adjustment capabilities for the subsequent pressing mechanism 205 to perform pressing operations and for the optical detection component 40 to perform optical detection. This design allows the equipment to adapt to materials of different thicknesses or types, ensuring the accuracy and consistency of the detection process.
[0057] Through the above technical solution, based on the material conveying component 20 conveying materials along the Y-axis, a combination of support plate 2021, reset part 2022, third drive 2023, and lifting component 2024 is introduced, enabling the material platform 203 to achieve precise and stable vertical lifting within the fixed frame 204. This design effectively solves the problem of high vertical positioning accuracy requirements during material pressing and optical inspection. Specifically, the cooperation of the third drive 2023 and the lifting component 2024 can precisely adjust the material platform 203 to the required height according to the inspection or pressing needs, ensuring that the material maintains the optimal working distance and contact state between the material and the pressing mechanism 205 or the optical inspection component 40. At the same time, the presence of the reset part 2022 provides a buffer or auxiliary reset function for the descent of the material platform 203, further improving the stability and reliability of the system. Therefore, this solution significantly improves the adaptability of the fully automatic optical inspection equipment to different materials and the accuracy and efficiency of inspection and pressing operations.
[0058] This application further proposes that the material platform 203 includes a material table 2031 disposed at the movable end of the reset part 2022, and a guide rod 2032 is provided on the side of the material table 2031 near the support plate 2021.
[0059] In one specific implementation, the material platform 2031 can be made of high-strength aluminum alloy sheet, with its surface anodized to improve wear resistance and corrosion resistance. The bottom of the material platform 2031 can have multiple support points that contact the elastic element of the reset part 2022. The guide rods 2032 can specifically be two precision-ground stainless steel guide rods with a diameter of 8mm, which are fixed parallel to each other on the lower surface of the material platform 2031 near the support plate 2021. When the third drive 2023 drives the lifting member 2024 to move along the X-axis, the lifting member 2024 abuts against the guide rods 2032 and gradually pushes the material platform 2031 upward, ensuring that the material platform 2031 rises smoothly in a precise vertical direction, avoiding any lateral deviation or tilting.
[0060] In some of the embodiments described above in this application, a fully automated optical inspection device is proposed, which uses a material conveying component 20 to transport materials to a material platform 203 inside a fixed frame 204 for processing. However, after the materials have been inspected or processed, how to efficiently and accurately grab the materials and send them to the inside of the fixed frame 204 and remove them from the fixed frame 204 for subsequent conveying, so as to avoid interference or improve space utilization, is a problem that needs further consideration.
[0061] In this regard, this application further proposes a clamping and conveying mechanism 206, which includes a fourth drive 2061 disposed on one side of the fixed frame 204. The output end of the fourth drive 2061 is connected to the positioning seat 2062. The positioning seat 2062 is rotatably provided with a turning part 2063 on the side away from the fourth drive 2061. A connecting frame 2064 is provided on the side of the turning part 2063 near the fixed frame 204. A clamping plate 2065 is provided on the side of the connecting frame 2064 away from the turning part 2063.
[0062] The fourth drive 2061 is the component that provides power to the clamping and conveying mechanism 206 to achieve its movement. The fourth drive 2061 can be a stepper motor, achieving positioning and rotation through precise control of its step angle; it can also be a servo motor, providing high-precision and high-response rotary drive; or it can be a pneumatic rotary actuator, achieving rotary motion through pneumatic drive. The positioning seat 2062 serves as the connection and support structure between the fourth drive 2061 and the steering part 2063, ensuring that the steering part 2063 can rotate stably. The positioning seat 2062 can be a bracket with precision bearings, providing low-friction rotary support for the steering part 2063; or it can be a base connected to the fourth drive 2061 via a pin, allowing the steering part 2063 to rotate on it. The steering part 2063 is the core component realizing the rotation function of the clamping and conveying mechanism 206. It can change the posture and conveying direction of the clamping plate 2065. The steering part 2063 can be a rotary disk driven by a gear set, achieving precise angular positioning.
[0063] Furthermore, in order to ensure the precise rotation of the steering part 2063, a micro stepper motor for driving the rotation of the steering part 2063 is provided in the positioning seat 2062, and the output end of the micro stepper motor is connected to a set of steering parts 2063 above.
[0064] The connecting frame 2064 connects the steering part 2063 and the clamping plate 2065, transmitting the rotational motion of the steering part 2063 to the clamping plate 2065 and maintaining the relative position of the clamping plate 2065. The connecting frame 2064 can be a rigid rod to ensure the accuracy of motion transmission. The clamping plate 2065 is the component that directly contacts the material and performs clamping, fixing, and conveying. The clamping plate 2065 can be composed of two relatively movable plates, driven by the steering part 2063 and the connecting frame 2064. The clamping plate 2065 is driven by the circular disk of the steering part 2063 itself. The clamping end face of the clamping plate 2065 has a slight tilt angle. With the tilted chamfered end face, the rotation clamping fits the chip surface. When released, it rotates to the upper and lower outer sides of the fixing frame 204 without affecting the lifting and lowering of the support member 202.
[0065] The solution of this application involves setting a clamping and conveying mechanism 206 on one side of the fixed frame 204. This mechanism is powered by a fourth drive 2061, which drives the positioning seat 2062 and the steering part 2063 to move in the X-axis direction. The steering part 2063 can rotate and, through the connecting frame 2064, drives the clamping plate 2065 to rotate accordingly, clamping the material and moving it to the detection position through the fourth drive 2061. After the material has been detected or processed on the material platform 203, the steering part 2063 clamps the material again, and the fourth drive 2061 drives it to move upward in the X-axis, rotating the material from the inside of the fixed frame 204 to the external discharge position through the clamping plate 2065.
[0066] In practical applications, ensuring that the pressing mechanism 205 can stably and accurately press the material to guarantee the accuracy and repeatability of subsequent optical inspection is a problem that needs to be solved. If the pressing force or pressing position of the pressing mechanism 205 is unstable, it may cause the material to shift or deform during the inspection process, thereby affecting the reliability of the inspection results.
[0067] In this regard, this application further proposes that the pressing mechanism 205 includes a fifth drive 2051 fixedly mounted on the fixed frame 204, the output end of the fifth drive 2051 is connected to the substrate 2052, and a pressing rod 2053 is provided on one side of the substrate 2052.
[0068] The fifth drive 2051 is a drive device used to provide power to the pressing mechanism 205 to achieve the pressing action on the material. Its function is to generate controllable linear or rotary motion, thereby driving the pressure rod 2053 to press the material. The fifth drive 2051 can take various forms. For example, it can be an electric push rod, which converts rotary motion into linear motion through a motor-driven screw and nut mechanism, featuring controllable stroke and stable thrust; or it can be a cylinder, which uses the pressure of compressed air to push the piston to generate linear motion, featuring fast response speed and simple structure.
[0069] The substrate 2052 is a connector used to connect the output end of the fifth drive 2051 and the pressure rod 2053. Its function is to transmit the power or motion generated by the fifth drive 2051 to the pressure rod 2053 and to serve as a support structure for the pressure rod 2053. The substrate 2052 can be in the form of a rigid connecting plate, connected to the fifth drive 2051 and the pressure rod 2053 by bolts or other fasteners, ensuring the stability and rigidity of force transmission and facilitating adjustment of the position or angle of the pressure rod 2053 relative to the fifth drive 2051. The pressure rod 2053 is the component that directly contacts the material and applies pressure. Its function is to locally or entirely compress the material to fix its position, eliminate material warping or deformation, and ensure a flat material surface, thereby providing stable detection conditions for optical inspection.
[0070] The solution of this application provides a pressing mechanism 205 on the outside of the fixing frame 204. This pressing mechanism 205 includes a fifth drive 2051, a substrate 2052, and a pressing rod 2053. When the material conveying assembly 20 delivers the material to be tested to the designated position, the fifth drive 2051 is activated, and its output end drives the substrate 2052 to move. The substrate 2052 transmits the movement of the fifth drive 2051 to the pressing rod 2053, causing the pressing rod 2053 to move downwards and contact the material on the material platform 203. The pressing rod 2053 applies a preset pressure to the material, stably pressing the material onto the material platform 203. This pressing action ensures that the material is in a stable and flat state when the optical detection assembly 40 performs detection, thus providing a prerequisite for the optical detection assembly 40 to obtain clear and accurate images or data.
[0071] In summary, the fully automatic optical inspection equipment of this application embodiment achieves automatic conveying, precise positioning and fixing of the test object through the coordinated action of the material conveying component, the pressing mechanism and the clamping conveying mechanism. It has the advantages of achieving automatic and precise positioning and fixing of the test object, reducing deformation and displacement, and improving inspection efficiency and automation level.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
