[0002] IC substrates, also known as IC packaging substrates, are a key specialized base material used for packaging integrated circuit card modules or chips. Their main functions include protecting the chip, serving as the interface between the integrated circuit chip and the external environment, and also providing heat dissipation. With technological and industrial development, the demand for IC substrates has increased significantly across various industries, leading to increasingly stringent requirements for their processes, integration levels, quality, and production efficiency. Therefore, defect detection of IC substrates is necessary before they leave the production line.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.
[0035] like Figure 1 - Figure 5 As shown, the double-sided detection motion stage device 1 provided in this application includes:
[0036] The transportation mechanism 10 includes a first drive component 11 and a transportation platform 13. The first drive component 11 drives the transportation platform 13 to move the transportation platform 13 back and forth in a straight line.
[0037] Platform 20, platform 20 is connected to transport platform 13;
[0038] The clamping mechanism 30 includes a fixed end assembly 31, a movable end assembly 32, and a moving assembly 33. The moving assembly 33 is disposed on the transport platform 13, while the fixed end assembly 31 and the movable end assembly 32 are disposed on the platform 20. The moving assembly 33 is driven to connect to the movable end assembly 32 to drive the movable end assembly 32 to reciprocate linearly. The movable end assembly 32 includes a second driving member 321, a first main body 322, a first pressing block 323, and a first pressing rod 324. The first main body 322 is movably disposed on the platform 20, and the second driving member 321 is disposed on the first main body 322. The second driving member 321 is driven to connect to one end of the first pressing rod 324. The other end of the rod 324 is connected to the first pressure block 323. The second driving member 321 drives one end of the first pressure rod 324 to rotate so that the other end moves closer to or away from the platform 20. The fixed end assembly 31 includes a third driving member 311, a second body 312, a second pressure block 313, and a second pressure rod 314. The second body 312 is disposed on the platform 20. The third driving member 311 is disposed on the second body 312. The third driving member 311 drives one end connected to the second pressure rod 314. The other end of the second pressure rod 314 is connected to the second pressure block 313. The third driving member 311 drives one end of the second pressure rod 314 to rotate so that the other end moves closer to or away from the platform 20.
[0039] The first driving component 11 is a power source (such as a motor, cylinder, linear module, etc.) that drives the transport platform 13. The transport platform 13 is a basic platform used to support the platform 20 and move back and forth in a straight line.
[0040] Optionally, the first driving component 11 can be a motor drive, a cylinder drive, or a linear motor. A motor drive uses a servo motor and a 333 ball screw / synchronous belt, featuring high control precision and suitability for long strokes and high loads; a cylinder drive uses a single / double-acting cylinder and a magnetic switch, featuring fast response and low cost; a linear motor is a contactless electromagnetic drive, used with a linear guide rail, featuring no mechanical wear and high speed.
[0041] The function of the transport mechanism 10 is to drive the transport platform 13 to move via the first driving component 11 (such as a motor or cylinder), enabling the carrier 20 to move back and forth between the inspection station and the loading / unloading station, thus realizing the transfer of IC carrier boards. Furthermore, through precise control of the first driving component 11 (such as the speed of the servo motor and the stroke of the cylinder), the moving speed and positional accuracy of the transport platform 13 are ensured, preventing the carrier board from shaking or shifting during movement. In addition, the transport mechanism 10 can replace manual handling, improving inspection efficiency; its linear reciprocating motion mode is suitable for assembly line operations and facilitates linkage with vision inspection equipment, loading / unloading robotic arms, etc.
[0042] The transport platform 13 can be made of aluminum alloy, cast iron, or carbon fiber composite material. Aluminum alloy is lightweight and easy to process, making it suitable for small to medium-sized platforms 20. Cast iron has high rigidity and good shock resistance, making it suitable for heavy-duty platforms 20. Carbon fiber composite material has high rigidity and low weight, making it suitable for high-speed motion scenarios.
[0043] The moving component 33 converts rotary motion into linear motion via a lead screw 333 (or a similar mechanism), driving the movable end component 32 to move laterally along the platform 20. High-precision transmission (such as a servo motor and ball screw 333) enables millimeter-level positioning, adapting to IC carrier boards of different widths. Furthermore, during the loading and unloading stages, the moving component 33 can drive the movable end component 32 away from the carrier board, avoiding interference with the robotic arm's pick-and-place actions.
[0044] The stage 20 directly supports the IC carrier board and serves as the mounting base for the clamping mechanism 30, requiring sufficient strength and flatness. It is fixed to the transport platform 13 via connectors 23 (such as bolts or guide rail sliders 336) to ensure synchronized movement. If the stage 20 is made of a transparent material (such as acrylic), it can support bottom visual inspection, enabling double-sided inspection to be completed in one go without flipping the carrier board. In essence, the stage 20 provides a stable inspection reference surface for the IC carrier board and serves as an intermediate carrier in the mechanical structure, connecting the transport mechanism 10 and the clamping mechanism 30.
[0045] The movable end assembly 32 includes a second drive member 321, a first body 322, a first pressure block 323, and a first pressure rod 324. The second drive member 321 is a power source (such as a cylinder or micro motor) that drives the first pressure rod 324 to rotate. The first body 322 is the mounting base of the movable end assembly 32 and slides on the stage 20 driven by the moving component 33. The first pressure rod 324 connects the second drive member 321 and the first pressure block 323, and its rotation enables the pressure block to rise and fall. The first pressure block 323 is an actuator that directly contacts the IC carrier board and is made of a flexible material. The movable end assembly 32 uses flexible clamping to avoid scratching the surface of the carrier board, making it suitable for precision component testing.
[0046] The lifting logic of the pressure block is that the second driving component 321 (such as a cylinder) pushes one end of the first pressure rod 324 to rotate upward, and the other end drives the first pressure block 323 to press down on the carrier plate; when driven in the reverse direction, the pressure block is lifted and the carrier plate is released (similar to the lever principle).
[0047] The fixed end assembly 31 includes a third driving member 311, a second main body 312, a second pressure block 313, and a second pressure rod 314. The third driving member 311 functions similarly to the second driving member 321 of the movable end, driving the second pressure rod 314 to rotate. The second main body 312 is fixed to the other side of the platform 20, serving as the mounting reference for the fixed end. The second pressure rod 314 connects the third driving member 311 and the second pressure block 313, transmitting driving force. The second pressure block 313 is made of the same material as the first pressure block 323, providing clamping force on the fixed side. The fixed end assembly 31 serves as a positioning reference, with the fixed end position remaining unchanged, acting as a reference surface for the lateral positioning of the carrier plate, ensuring accurate spacing between the pressure blocks on both sides when the movable end moves. Additionally, the fixed end assembly 31 also has a clearance function, using a clearance cylinder 315 to temporarily move the second main body 312 to avoid the loading and unloading paths, preventing mechanical interference.
[0048] The clamping mechanism 30 consists of a fixed end assembly 31, a movable end assembly 32, and a moving assembly 33, which work together to achieve bidirectional clamping of the IC carrier board. The fixed end assembly 31 is connected to one side of the stage 20 and provides a reference clamping force; the movable end assembly 32 is driven by the moving assembly 33 and can move laterally along the stage 20 to adapt to carrier boards of different sizes. Through bidirectional clamping, pressure is applied synchronously from both sides of the carrier board to ensure that the carrier board does not shift during testing and that the force is uniform.
[0049] The movable end component 32 and the fixed end component 31 cooperate: the movable end is movable (via the movable component 33), and the fixed end is fixed to the stage 20. The two are pressed together from both sides of the IC carrier board to ensure that the carrier board is stable and does not shake during testing.
[0050] The movement of the pressure block: The pressure rod is driven to rotate by a drive component (such as a cylinder or motor), so that the pressure block is raised and lowered vertically. This structure saves more space than linear push and pull, and the force is evenly distributed, avoiding deformation of the carrier plate.
[0051] The workflow is as follows: the moving component 33 drives the movable end away from the platform 20, and the fixed end retracts the clearance cylinder 315, releasing space for the carrier board; the external robotic arm places the IC carrier board into the positioning slot of the platform 20, and the transport mechanism 10 drives the platform 20 to move to the inspection station. The moving component 33 adjusts the movable end to the left side of the carrier board, and the second driving component 321 drives the first pressing block 323 to press down; the third driving component 311 simultaneously drives the second pressing block 313 of the fixed end to press down, achieving clamping on both sides of the carrier board. The transport mechanism 10 moves the platform 20 to the visual inspection area, where the transparent platform 20, with the bottom camera, captures the back of the carrier board, and the top camera captures the front; after inspection, the pressing block is lifted, the movable end is cleared, and the platform 20 returns to the unloading station.
[0052] This application addresses the issues of scratches and uneven pressure caused by manual clamping through the cooperation of the movable and fixed ends, using a flexible clamping block and spring mechanism. Furthermore, the high-precision control of the transport mechanism 10 and the moving component 33 enables automatic transport and adaptive positioning of the carrier plate, improving efficiency. Moreover, the transparent material supports double-sided visual inspection, and the flexible clamping block protects the precision carrier plate, demonstrating targeted optimization of the inspection process.
[0053] Furthermore, the platform 20 includes a base plate 21, a clamping member 22, and a connecting member 23. One end of the connecting member 23 is connected to the base plate 21, and the other end is connected to the transport platform 13. The clamping member 22 is connected to the edge of the base plate 21.
[0054] The base plate 21 serves as the basic support structure for the platform 20, supporting the IC carrier and fixing other components (such as the clamping mechanism 30). The connector 23 connects the base plate 21 to the transport platform 13, ensuring the stability of the platform 20 during transport and potentially transmitting driving forces (e.g., the movement of the transport platform 13 drives the platform 20 to move synchronously via the connector 23). Clamping elements 22 (such as elastic rubber strips) at the edges of the base plate 21 assist in fixing the IC carrier, preventing it from shifting during transport or clamping, especially suitable for carriers that are small or irregularly shaped. Optionally, the clamping element 22 can be an elastic clamping strip or a magnetic clamping element 22. The elastic clamping strip can be a silicone strip or a polyurethane strip, while the magnetic clamping element 22 includes an electromagnetic chuck and a rubber pad, fixing the carrier by electromagnetic force. The rubber pad prevents scratches and is suitable for metal carriers.
[0055] In this embodiment, there are two clamping members 22 and two connecting members 23. Both clamping members 22 and connecting members 23 are connected to the two side edges of the transport platform 13, respectively. This design ensures the stability and balance of the platform 20 on the transport platform 13. The two clamping members 22 are located on the two side edges of the base plate 21, respectively, and can apply pressure evenly, effectively preventing any displacement of the IC carrier board during transportation. Simultaneously, the two connecting members 23 are also connected to both sides of the base plate 21, which not only enhances the connection strength between the platform 20 and the transport platform 13, but also better transmits driving force, ensuring that the platform 20 can move smoothly with the transport platform 13. This double-sided clamping and connecting design improves the stability and reliability of the entire device, making the double-sided detection motion platform device run more smoothly and the detection results more accurate.
[0056] Furthermore, the moving component 33 includes a fourth driving member 331, a support base 332, a lead screw 333, and a lead screw nut mounting member 334. The support base 332 is disposed on the transport platform 13, the lead screw 333 is connected to the support base 332, the fourth driving member 331 drives the lead screw 333, one end of the lead screw nut mounting member 334 is movably connected to the lead screw 333, and the other end is connected to the first body 322. The fourth driving member 331 drives the lead screw 333 to rotate so as to drive the lead screw nut mounting member 334 and the first body 322 to reciprocate in a straight line.
[0057] The lead screw 333 drive features high precision and strong load capacity. The lead screw 333 nut pair can accurately convert rotary motion into linear motion, making it suitable for scenarios requiring precise positioning (such as position control when the movable end assembly 32 moves to the left end of the carrier plate). Compared to belt drive, the lead screw 333 can withstand greater axial force, ensuring the stability and reliability of the movable end assembly 32 during movement.
[0058] In addition, the fourth drive component 331 is usually a servo motor, which achieves closed-loop control through encoder feedback to ensure that the moving distance and speed of the moving end component 32 are controllable.
[0059] Furthermore, when the size of the IC carrier board changes, the position of the movable end can be adjusted by the moving component 33 to adapt to carrier boards of different specifications, thereby improving the versatility of the device.
[0060] In addition to using a ball screw 333 and a servo motor for screw 333 transmission, a gear and rack drive method using helical gears and racks, or a synchronous belt drive method using polyurethane synchronous belts and idler pulleys can also be used.
[0061] Furthermore, the movable end assembly 32 also includes a rotating shaft 325, a rotating shaft pressure member 326, a first spring guide rod 327, and a first spring adjustment member 328. One end of the rotating shaft 325 is connected to the second drive member 321, and the other end is connected to the first pressure rod 324. One end of the rotating shaft pressure member 326 is connected to the first main body 322, and the other end is connected to the side of the first pressure rod 324 near the rotating shaft 325. The first spring adjustment member 328 is connected to the first main body 322. One end of the first spring guide rod 327 is connected to the first spring adjustment member 328, and the other end abuts against the rotating shaft pressure member 326.
[0062] Specifically, an elastic adjustment structure is added. The elastic pressure adjustment, through a spring guide rod and an adjusting component (such as a compression spring), buffers the pressure block when it contacts the carrier plate, preventing damage to the carrier plate (especially thin or sensitive component carrier plates) due to excessive pressure. Furthermore, the elastic deformation of the spring can compensate for carrier plate thickness tolerances, ensuring that carrier plates from different batches can be reliably compressed. The rotating shaft pressure component 326, as an intermediate component for force transmission, evenly transmits the spring force to the pressure rod, while simultaneously raising and lowering the pressure block through the rotation of the rotating shaft 325.
[0063] Furthermore, the active end assembly 32 also includes a measuring cylinder 329, a cylinder fixing block 3210, a mounting base 3211, and a sensor 3213. The cylinder fixing block 3210 is connected to the lead screw nut mounting member 334, the measuring cylinder 329 is mounted on the cylinder fixing block 3210, the mounting base 3211 is fixedly connected to the measuring cylinder 329, and the sensor 3213 is mounted on the mounting base 3211.
[0064] Specifically, the measuring cylinder 329 is used to assist in detecting the length of the carrier plate (e.g., to determine whether the carrier plate is correctly placed by measuring the extension length of the cylinder) or to provide pre-clamping force during the clamping process. The sensor 3213 can be a position detection sensor 3213 or a pressure sensor 3213. The position detection sensor 3213, such as a proximity switch, detects whether the movable end assembly 32 has moved into place (e.g., reached the left end of the carrier plate). The pressure sensor 3213 can monitor the actual pressure of the pressure block on the carrier plate to ensure that the clamping force is within the set range and to avoid over- or under-pressure.
[0065] The measuring cylinder 329 can be a magnetostrictive displacement sensor cylinder or a pressure control cylinder. The sensor 3213 can be a fiber optic sensor or a laser displacement sensor.
[0066] Furthermore, the fixed end assembly 31 also includes a repositioning cylinder 315, which is disposed on the platform 20 and is driven to be connected to the third body to drive the third body to reciprocate along a straight line.
[0067] When the IC carrier needs to be grasped or placed by an external robotic arm, the third body (which may include a pressure block) at the fixed end must move away via the avoidance cylinder 315 to avoid interfering with the robotic arm's movements. After the inspection is completed, the avoidance cylinder 315 drives the third body to retract, making it easier for the carrier to be picked up by the unloading mechanism. Through the avoidance action, the device and the unloading equipment can work together, improving the smoothness of the automated process and avoiding mechanical collisions.
[0068] Furthermore, the fixed end assembly 31 also includes a fixed pressure member 316, a second spring guide rod, and a second spring adjustment member 318. The second spring adjustment member 318 is connected to the second main body 312. One end of the second spring guide rod is connected to the second spring adjustment member 318, and the other end abuts against one end of the fixed pressure member 316. The other end of the fixed pressure member 316 abuts against the second pressure rod 314.
[0069] Specifically, similar to the movable end assembly 32, the fixed end assembly 31 also incorporates an elastic pressure adjusting fixed end pressure block, typically used as a positioning reference. The elastic pressure ensures that the carrier plate neither slips nor shifts or deforms due to rigid pressure when clamped; the spring adjustment element can adjust the pressure according to the carrier plate material (such as a rigid or flexible substrate), enhancing the adaptability of the device. Both the movable end (movable) and the fixed end (fixed) employ elastic clamping, forming a "two-way elastic clamping" effect, further improving the stability and protection of the carrier plate.
[0070] Furthermore, the moving component 33 also includes a slide rail 335 and two sliders 336. The slide rail 335 is disposed on the platform 20 and is arranged parallel to the first driving member 11. The two sliders 336 are slidably connected to the slide rail 335. The first body 322 and the second body 312 are respectively mounted on the two sliders 336.
[0071] Specifically, the slide rail 335 provides a linear motion track for the movable end assembly 32 (first body 322) and the fixed end assembly 31 (second body 312), ensuring accurate movement direction and avoiding deviation or wobbling; the slider 336 typically uses linear bearings or rolling guides to reduce motion resistance and improve transmission efficiency and mechanism life. The lead screw 333 provides driving force, and the slide rail 335 provides guidance; the combination of the two achieves high-precision linear motion, ensuring that the movable end assembly 32 can accurately align with the edge of the carrier plate.
[0072] Furthermore, the first pressing block 323 includes a connecting part 3231 and a pressing part 3233 connected to each other. The connecting part 3231 and the pressing part 3233 are vertically connected. The connecting part 3231 is connected to the first pressing rod 324, and the pressing part 3233 is used to press against the IC carrier board.
[0073] Specifically, the connecting part 3231 is vertically connected to the pressure rod, facilitating the transmission of force (the rotation of the pressure rod is converted into the vertical lifting and lowering of the clamping part 3233). The clamping part 3233 directly contacts the working surface of the carrier board, and its shape (such as a flat surface or a toothed surface) can be designed according to the surface characteristics of the carrier board to increase friction and prevent slippage, while avoiding scratching the carrier board. In addition, the area and shape of the clamping part 3233 need to be adapted to the edge structure of the IC carrier board. For example, for a narrow bezel carrier board, the clamping part 3233 can be designed as a thin sheet to ensure accurate clamping position.
[0074] Furthermore, the first pressing block 323 and the second pressing block 313 are made of polyvinyl chloride or rubber;
[0075] And / or, the stage 20 is set to be transparent.
[0076] Specifically, the first pressure block 323 and the second pressure block 313 are made of polyvinyl chloride (PVC) or rubber. Both PVC and rubber are flexible materials with high surface friction, which can buffer the clamping force and prevent scratches on the carrier plate caused by rigid contact; they also have a certain degree of elasticity to adapt to minor unevenness on the carrier plate surface. If metal is used, it is easy to scratch the carrier plate and lacks elastic compensation, so flexible materials are more suitable for precision testing scenarios. Furthermore, the first pressure block 323 and the second pressure block 313 are transparent. Using transparent soft pressure blocks will not damage the material or obstruct the view, perfectly solving the problems of insufficient cycle time at slow speeds and friction on the product at high speeds. Alternatively, the first pressure block 323 and the second pressure block 313 can also be made of silicone rubber or polyurethane rubber.
[0077] Additionally, the transparent stage 20 facilitates visual inspection systems (such as cameras) to photograph the back of the IC substrate from below, eliminating the need to flip the substrate during double-sided inspection and simplifying the process. Furthermore, the transparent material (such as acrylic) must possess sufficient strength to support the weight of the substrate and the clamping mechanism 30. Optionally, the transparent stage 20 can be made of acrylic, optical glass, or transparent PC sheet. Acrylic has poor scratch resistance and is prone to yellowing over long-term use; optical glass is heavy and has weak impact resistance, requiring shatterproof treatment; transparent PC sheet has good high-temperature resistance (120℃), making it suitable for high-temperature inspection environments.
