Description

Technical Field

[0001] This invention relates to the field of semiconductor manufacturing technology, and in particular to a chip module suction nozzle machine and control method. Background Technology

[0002] In the semiconductor manufacturing and advanced packaging fields, efficient and precise wafer transfer is a core element in ensuring overall production yield and manufacturing efficiency, spanning every process stage from wafer processing, inspection, mounting to final packaging. In existing technologies, wafer transfer devices typically employ robotic arms with gripper structures to grasp and place materials. These robotic arms apply clamping force to the wafer edges or specific areas through the opening and closing of their grippers, thereby completing the transfer of materials between different workstations.

[0003] However, during the material handling process for the optical core modules, multiple materials are placed on the carrier in a parallel and closely spaced arrangement, with almost no gap between adjacent materials for the robotic arm's gripper to insert. Since existing robotic arms require their grippers to reach in from the side or top of the materials for effective grasping, the lack of this necessary operating space between the parallelly laid materials prevents the robotic arm from directly gripping the target material. This necessitates additional steps to separate the materials one by one, significantly increasing the operational complexity and time consumption during the transfer process, thereby severely reducing the overall material transfer efficiency and hindering further increases in production line capacity. Summary of the Invention

[0004] The purpose of this invention is to provide a light core module suction nozzle machine and control method that can quickly extract materials even when multiple materials are laid in parallel and side by side, thereby improving material transfer efficiency.

At least two suction nozzle assemblies are circumferentially spaced on the outer peripheral wall of the rotary table. The rotary drive mechanism can drive the rotary table to rotate, so that one of the at least two suction nozzle assemblies is in a working position. The lifting module includes a base plate and a lifting drive mechanism. The lifting drive mechanism is disposed on the base plate, and the mounting crank arm is disposed on the lifting drive mechanism. The lifting drive mechanism is used to drive the suction module to move along a first direction.

[0008] As an optional solution for the optical core module suction nozzle machine, the suction module further includes: A floating anti-collision elastic element is sandwiched between the first stroke limiter and the suction nozzle assembly to buffer the impact force when the suction nozzle assembly comes into contact with the material.

[0009] As an optional solution for the optical core module suction nozzle machine, the suction nozzle assembly is equipped with a displacement detection sensor, which is configured to detect the amount of compression of the floating anti-collision elastic element during the rebound process of the suction nozzle assembly.

[0010] As an optional solution for the optical core module suction nozzle machine, the suction nozzle assembly is provided with multiple vacuum ports spaced apart along the second direction for adsorbing materials.

[0011] As an optional solution for optical core module suction nozzle machines, at least two suction nozzle components have different adsorption forces.

[0012] As an optional solution for the optical core module nozzle machine, a fan-shaped baffle is provided on the rotating platform, and an origin induction switch is provided on the mounting crank arm. Rotating the rotating platform can cause the fan-shaped baffle to trigger the origin induction switch.

[0013] The control method, applied to the material handling of the optical core module nozzle machine as described in any of the preceding claims, includes the following steps: Move the optical core module suction nozzle machine above the material; Depending on the type of material to be adsorbed, rotate to switch to the corresponding suction nozzle assembly; The lifting drive mechanism drives the suction module to descend along the first direction and approach the material; After the suction nozzle assembly picks up the material, the lifting drive mechanism drives the suction module to rise along the first direction; Move the optical core module suction nozzle machine to the feeding area to complete the material transfer.

[0014] As an alternative control method, when the suction nozzle assembly contacts the material and floats upward due to obstruction, an alarm module is activated when the compression of the floating anti-collision elastic element exceeds a preset value.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The optical core module suction machine provided by this invention includes a suction module comprising a mounting arm, a rotary drive mechanism, a rotary table, and at least two suction nozzle assemblies.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] To enable rapid extraction even when multiple materials are laid parallel and side-by-side, thus improving material transfer efficiency, this embodiment provides a photonic core module nozzle machine and a control method, which are described below in conjunction with... Figures 1 to 4 The specific content of this embodiment will be described in detail below. It should be noted that the first direction mentioned in this embodiment is the Z direction, and the second direction mentioned in this embodiment is the Y direction.

[0025] The optical core module suction machine provided in this embodiment includes two core functional modules: a suction module 001 and a lifting module 002. These two modules work together to achieve efficient and precise material transfer. The suction module 001 is the execution unit that performs the material gripping and releasing actions. The suction module 001 includes a mounting arm 1, a rotary drive mechanism 2, a rotating table 3, and at least two suction nozzle assemblies 4. Each suction nozzle assembly 4 is equipped with a vacuum tube interface 42. The rotary drive mechanism 2 is mounted on the mounting arm 1, and the rotating table 3 is connected to the output shaft of the rotary drive mechanism 2, allowing the rotating table 3 to rotate around its axis under the drive of the rotary drive mechanism 2. At least two suction nozzle assemblies 4 are circumferentially spaced on the outer wall of the rotating table 3, maintaining a fixed angular distance between each assembly and preventing interference. The rotary drive mechanism 2 can selectively rotate the rotating table 3, allowing any one of the at least two suction nozzle assemblies 4 to precisely rotate to the working position to perform material suction or placement operations. This rotary switching design allows the suction machine to quickly switch between different suction nozzle components 4 without significant overall movement, effectively shortening the time for station switching. The lifting module 002 is a support unit that provides vertical movement capability for the suction module 001. The lifting module 002 includes a base plate 0021 and a lifting drive mechanism 0022. The lifting drive mechanism 0022 is mounted on the base plate 0021, and the mounting arm 1 is mounted on the lifting drive mechanism 0022. The lifting drive mechanism 0022 drives the suction module 001 to reciprocate along a first direction, thereby realizing the lifting movement of the suction nozzle component 4 between different height stations, completing the picking up of materials from the carrier and placement on the target station. In this embodiment, the rotary table 3 and the output shaft of the rotary drive mechanism 2 are coaxially connected, facilitating easy assembly and disassembly.

[0026] In this embodiment, the optical core module suction machine, when faced with a typical working condition where multiple materials are laid out parallel and closely side-by-side, with no gaps between adjacent materials for the gripper to insert, utilizes vacuum suction force rather than mechanical clamping force to grasp the materials. Its operation involves applying negative pressure to the upper surface of the materials, thus completely independent of the presence of operational gaps on the sides of the materials. Even when adjacent materials are tightly packed together without any gaps, the suction component 4 can still quickly and reliably suction and lift the target material. This fundamentally overcomes the problem of existing robotic grippers being unable to directly grasp materials due to a lack of insertion gaps, significantly improving material transfer efficiency. Furthermore, by adding at least two suction components 4 to the rotary table 3 and employing a dual-suction redundancy design, the optical core module suction machine can simultaneously transfer multiple materials in a single work cycle, eliminating the need for multiple pick-and-place operations. This reduces the average transfer time required for a single material, further shortening the waiting time between processes, thereby further improving overall material transfer efficiency.

[0027] Furthermore, the outer peripheral wall of the rotary table 3 is provided with at least two guide rails 31, which extend tangentially along the rotary table 3. The suction module 001 also includes at least two sliders 5, and each suction nozzle assembly 4 is slidably connected to the corresponding guide rail 31 on the outer peripheral wall of the rotary table 3 via a slider 5. Specifically, the slider 5 is movably mounted on the guide rail 31 and can slide freely along the extension direction of the guide rail 31, while being constrained by the guide rail 31 to prevent offset or wobbling, thereby ensuring the stability and guiding accuracy of the suction nozzle assembly 4 during movement. In actual operation, the lifting module 002 drives the mounting crank arm 1 and the entire suction module 001 to move downwards in the first direction, so that the suction nozzle assembly 4 gradually approaches and finally contacts the material surface on the carrier. During this descent, when the lower end face of a certain suction nozzle assembly 4 first contacts the upper surface of the material, if the lifting module 002 continues to apply downward pressure due to inertia or control delay, in a traditional rigid connection structure, the continued descent of the lifting module 002 will directly translate into rigid compression of the material by the suction nozzle assembly 4. This can easily crush or damage the material due to excessive pressure, especially for precision and fragile components such as optical core modules. Once subjected to excessive compression, it will directly lead to product scrapping and cause serious yield losses. However, in the structural design of this embodiment, since the suction nozzle assembly 4 forms a slidable connection with the guide rail 31 through the slider 5, when the suction nozzle assembly 4 is subjected to an upward reaction force after contacting the material, this reaction force will be transmitted to the guide rail 31 through the slider 5 and converted into the power for the slider 5 to slide upward along the guide rail 31. At this point, even if the lifting module 002 continues to move downward, the suction nozzle assembly 4 itself can slide upward relative to the rotary table 3 along the guide rail 31, thereby stopping the descent and preventing further rigid contact and compression between the suction nozzle assembly 4 and the material.

[0028] Furthermore, a first travel limiter 6 and a second travel limiter 7 are respectively disposed at both ends of the guide rail 31. These two limiters are located at the two endpoints of the guide rail 31 in the extension direction and are fixedly connected, together forming a rigid constraint boundary on the movement range of the slider 5. Correspondingly, during the sliding process of the slider 5 along the guide rail 31, the two extreme positions of the slider 5 are blocked by the first travel limiter 6 and the second travel limiter 7, respectively. That is, the slider 5 stops between the first travel limiter 6 and the second travel limiter 7 and cannot continue to slide beyond either limiter. In this embodiment, by adding the first travel limiter 6 and the second travel limiter 7 at both ends of the guide rail 31, the movable travel range of the slider 5 and the suction nozzle assembly 4 connected thereto on the guide rail 31 can be accurately and reliably limited.

[0029] Furthermore, the suction module 001 also includes a floating anti-collision elastic element 8, which is sandwiched between the first stroke limiter 6 and the suction nozzle assembly 4. Specifically, one end of the floating anti-collision elastic element 8 abuts against the end face of the first stroke limiter 6, and the other end abuts against the end face of the suction nozzle assembly 4 facing the first stroke limiter 6. The two are always in a pre-compressed or pre-tightened elastic contact state, thereby establishing a force transmission path with elastic recovery capability between the suction nozzle assembly 4 and the first stroke limiter 6. In terms of the specific selection of the floating anti-collision elastic element 8, it can be a spring, such as a cylindrical helical compression spring, a disc spring, or an elastic rubber column, etc., which have good elastic recovery characteristics. This embodiment realizes the force buffer protection function during the material suction process. When the lifting module 002 drives the suction module 001 to descend along the first direction to perform the suction operation, the suction nozzle assembly 4 descends with the whole and gradually approaches the material surface. The instant the suction nozzle assembly 4 contacts the upper surface of the material, the material generates an upward contact reaction force on the suction nozzle assembly 4. This reaction force is first transmitted to the floating anti-collision elastic element 8 through the slider 5, forcing the floating anti-collision elastic element 8 to undergo further elastic compression deformation. This converts the kinetic energy of the suction nozzle assembly 4's continued descent into elastic potential energy within the elastic element for storage and absorption. Simultaneously, the elastic restoring force of the floating anti-collision elastic element 8 applies a reverse supporting force to the suction nozzle assembly 4, enabling it to quickly decelerate and stop descending after contact with the material, and even produce a slight upward rebound displacement. This completely avoids the suction nozzle assembly 4 exerting a continuously increasing rigid downward pressure on the material under inertia. By adding the floating anti-collision elastic element 8, the suction nozzle assembly 4 maintains its floating function throughout the entire process of contact with the material. When the suction nozzle assembly 4 encounters resistance during its descent due to factors such as material height deviation, carrier flatness error, or fluctuations in the control precision of the lifting module 002, the suction nozzle assembly 4 will not make a hard collision with the material. Instead, it will achieve flexible contact through the elastic compression and rebound of the floating anti-collision elastic element 8, i.e., "it can rebound when encountering resistance during downward pressure". This flexible buffering mechanism fundamentally eliminates the risk of damage such as material breakage, chip shattering, or surface scratches caused by rigid impact between the suction nozzle assembly 4 and the material.

[0030] Furthermore, a displacement detection sensor 9 is provided on the nozzle assembly 4. The displacement detection sensor 9 is configured to detect the amount of compression of the floating anti-collision elastic element 8 during the rebound process of the nozzle assembly 4. Specifically, the displacement detection sensor 9 is mounted and fixed on the nozzle assembly 4 and can accurately measure the real-time displacement distance of the nozzle assembly 4 relative to the slide rail. Since there is a definite correspondence between the displacement of the nozzle assembly 4 and the compression of the floating anti-collision elastic element 8, the actual compression of the floating anti-collision elastic element 8 during each material suction process can be indirectly and accurately obtained by real-time acquisition of the rebound displacement of the nozzle assembly 4 by the displacement detection sensor 9. When the detected compression of the floating anti-collision elastic element 8 is within the normal range, it indicates that the contact force between the nozzle assembly 4 and the material is below the safety threshold, and the material suction process proceeds normally. However, if the displacement detection sensor 9 detects that the compression of the floating anti-collision elastic element 8 exceeds the preset safety limit, i.e., the compression exceeds the limit, the system will immediately trigger the alarm mechanism and issue an abnormal prompt to the operator or host computer through audible and visual alarms, interface pop-ups, or production line control system signals, clearly informing that the contact pressure borne by the nozzle assembly 4 has exceeded the normal range and there is a risk of material being crushed.

[0031] Furthermore, the suction nozzle assembly 4 is provided with multiple vacuum ports 41 at certain intervals along the second direction (i.e., the direction parallel to the long side of the material). The vacuum ports 41 are used to adsorb the material. The vacuum ports 41 are arranged in a linear array on the bottom surface of the suction nozzle assembly 4, with a uniform spacing between adjacent vacuum ports 41. Each vacuum port 41 is independently connected to a vacuum generating device, which can synchronously or collaboratively generate negative pressure adsorption force when the suction nozzle assembly 4 contacts the material surface, thereby forming multiple discretely distributed adsorption points on the bottom surface of the suction nozzle assembly 4. In the actual production of optical core modules, some materials have a long strip structure. Due to their large length-to-width ratio, in the traditional scheme of adsorption with only a single vacuum port 41, the adsorption force is concentrated on a local area of ​​the material. The rest of the material, especially the suspended area far from the adsorption point, lacks sufficient support. When the suction nozzle assembly 4 lifts the material from the carrier, it is very easy for it to sag or bend due to its own weight, or even collapse as a whole in the case of uneven distribution of adsorption force. However, in this embodiment, by arranging multiple vacuum ports 41 at intervals along the second direction on the suction nozzle assembly 4, it is equivalent to establishing multiple independent adsorption anchor points along the length of the material, significantly increasing the effective adsorption area and the number of adsorption points for the long strip material. The negative pressure adsorption force generated by each vacuum port 41 acts on different positions along the length of the material, so that when the material is lifted, it is uniformly supported by adsorption from below along its entire length. This disperses the adsorption load, which was originally concentrated at a single point, to multiple adsorption points, greatly reducing the adsorption stress per unit area borne by any local area of ​​the material. This multi-point dispersed adsorption method effectively provides rigid support for the long strip material along its entire length, ensuring that the material remains flat and undeformed after being lifted.

[0032] Furthermore, the adsorption forces of at least two suction nozzle assemblies 4 are different, so that each of the at least two suction nozzle assemblies 4 has a specific adsorption force that matches the characteristics of its corresponding target material. Specifically, this embodiment uses two suction nozzle assemblies 4 as an example, one of which is defined as the main suction nozzle and the other as the backup suction nozzle. The two have clear differences in functional division and adsorption force parameters. The main suction nozzle is dedicated to the suction of chip materials, while the backup suction nozzle is dedicated to the suction of pad materials. Since chip materials are typically thin and lightweight, the adsorption force configured in the main suction nozzle is sufficient to meet the needs of stable suction and safe transfer, without requiring excessive suction. However, pad materials are thicker than chip materials, and require overcoming greater adsorption resistance during suction to achieve reliable separation. Therefore, the suction force of the backup suction nozzle is designed to be greater than that of the main suction nozzle, thereby ensuring that the backup suction nozzle can still provide sufficient and stable adsorption force when facing pad materials, avoiding slippage or falling of pad materials during transfer due to insufficient suction.

[0033] Furthermore, to achieve precise rotational switching and reliable positioning of the nozzle assembly 4 between the main nozzle and the backup nozzle, this embodiment includes a fan-shaped baffle 32 on the rotary table 3 and an origin induction switch 10 on the mounting arm 1. Rotating the rotary table 3 triggers the origin induction switch 10 via the fan-shaped baffle 32. The fan-shaped baffle 32 is fixedly mounted on the outer peripheral wall of the rotary table 3 and rotates synchronously with the rotary table 3. Its shape is a fan-shaped block structure. The origin induction switch 10 is mounted and fixed on the mounting arm 1, with its sensing surface facing the rotary table 3, and its sensing range corresponding to the movement trajectory of the fan-shaped baffle 32. The rotation drive mechanism 2 is activated and drives the rotary table 3 to rotate. During the rotation, the fan-shaped baffle 32 rotates together with the rotary table 3. When the triggering arc surface of the fan-shaped baffle 32 passes through the sensing range of the origin induction switch 10, the fan-shaped baffle 32 will trigger the origin induction switch 10 to send a detection signal. After the detection signal is transmitted to the control system, the control system determines that the rotary table 3 has reached the preset initial position. It then controls the rotary drive mechanism 2 to rotate the rotary table 3 to a precise preset angle and stop rotating, or stops rotating directly after reaching the preset angle, thus ensuring that the target suction nozzle assembly 4 (main suction nozzle or standby suction nozzle) is precisely aligned with the working position. The cooperation between the fan-shaped baffle 32 and the origin induction switch 10 ensures that the rotary table 3 can be precisely returned to zero after each rotation switch, eliminating the risk of the suction nozzle assembly 4 deviating from the working position due to accumulated errors in the rotation angle. This ensures that the main suction nozzle and standby suction nozzle can be aligned with the working position with extremely high repeatability after each switch, thereby guaranteeing the accuracy and consistency of the suction operation. Simultaneously, this origin positioning mechanism also allows the control system to precisely control the rotation angle of the rotary drive mechanism 2, ensuring that the angle of each rotation switch is a preset fixed value, avoiding abnormal situations such as incomplete rotation or over-rotation. This further improves the overall automation control level, material handling success rate, and production yield and operating efficiency of the optical core module suction nozzle machine.

[0034] This embodiment also provides a control method configured for use in the aforementioned optical core module suction nozzle machine for material handling and transfer operations. The control method includes the following steps: moving the optical core module suction nozzle machine above the material; rotating and switching to the corresponding suction nozzle assembly 4 according to the type of material to be adsorbed; the lifting drive mechanism 0022 driving the suction module 001 to descend along the first direction and approach the material; after the suction nozzle assembly 4 picks up the material, the lifting drive mechanism 0022 driving the suction module 001 to rise along the first direction; moving the optical core module suction nozzle machine to the discharge area to complete the material transfer.

[0035] Specifically, the control method includes the following steps: First, the positioning and movement step: The control system first drives the overall walking mechanism or rotating table 3 of the optical core module suction nozzle machine to precisely move the machine to a position directly above the carrier containing the material to be picked up, ensuring that the suction module 001 is within the vertical projection range of the material, thus establishing an accurate spatial position reference for subsequent suction operations. Second, the nozzle switching step: After the suction module 001 is in place, the control system automatically determines and selects the matching target nozzle assembly 4 based on the specific type of material to be absorbed. Specifically, if the material to be absorbed is a chip, the control system rotates the rotating table 3 by a preset angle, so that the main nozzle (with lower suction force, suitable for thin chips) is precisely aligned with the working position; if the material to be absorbed is a gasket, the control system rotates the rotating table 3 by another preset angle, so that the backup nozzle (with higher suction force, suitable for thick gaskets) is precisely aligned with the working position. During this switching process, the fan-shaped baffle 32 on the rotary table 3 rotates together with the rotary table 3. When the fan-shaped baffle 32 passes the origin induction switch 10 on the mounting crank arm 1, it triggers the origin signal. The control system confirms that the rotary table 3 has reached the precise preset angle and stops rotating, thereby ensuring the switching and positioning accuracy of the suction nozzle assembly 4. The third step is the descent and suction step: After the suction nozzle assembly 4 is switched and positioned, the lifting drive mechanism 0022 starts and drives the suction module 001 to descend at a constant or variable speed along the first direction (vertical downward direction), so that the target suction nozzle assembly 4, which has been positioned, gradually approaches and finally contacts the material surface. During this descent, if the suction nozzle assembly 4 contacts the material prematurely due to factors such as material height deviation or carrier flatness error, the floating anti-collision elastic element 8 is immediately compressed, and the suction nozzle assembly 4 slides in a straight line on the guide rail 31 and generates an upward floating rebound, thereby absorbing the contact impact force and preventing the material from being crushed. After the multiple vacuum ports 41 on the suction nozzle assembly 4 (a multi-point adsorption layout for elongated materials) fully adhere to the material surface and establish a stable negative pressure adsorption state, the material is reliably adsorbed and fixed on the suction nozzle assembly 4. The fourth step, the lifting and removal step: After the material is successfully adsorbed, the lifting drive mechanism 0022 reverses its movement, driving the suction module 001 to rise along the first direction (vertically upward), smoothly lifting the material off the carrier. During the lifting process, because the suction nozzle assembly 4 is equipped with multiple vacuum ports 41 spaced apart along the second direction, the material is uniformly adsorbed and supported along its entire length, effectively avoiding deformation problems such as central collapse or end bending of elongated materials due to single-point adsorption, ensuring that the material maintains a flat and stable posture after being lifted.Step 5, material handling and discharging: After the suction module 001 carries the material to a safe height, the control system drives the optical core module suction nozzle machine to move as a whole to the preset material discharging area. Then, the lifting drive mechanism 0022 drives the suction module 001 to descend along the first direction, so that the suction nozzle assembly 4 is close to the target carrier or fixture in the material discharging area, the vacuum adsorption is turned off, and the material is released, thereby completing the complete material transfer process for a single transaction.

[0036] Furthermore, this embodiment adds a real-time anomaly monitoring and alarm step based on the displacement detection sensor 9. Specifically, during the process of the suction nozzle assembly 4 contacting the material and floating upwards due to obstruction, the displacement detection sensor 9 continuously collects the rebound displacement data of the suction nozzle assembly 4 in real time, and calculates the real-time compression amount of the floating anti-collision elastic element 8 accordingly. The control system continuously compares this real-time compression amount with a preset safe compression threshold. When the compression amount of the floating anti-collision elastic element 8 exceeds the preset value, it indicates that the contact pressure currently borne by the suction nozzle assembly 4 has exceeded the normal safe range, and there is a risk of material damage. At this time, the control system immediately activates the alarm module and issues an abnormal pressure warning to the operator or the host computer through audible and visual alarms, interface pop-ups, or production line control system signals, so that the operator can promptly investigate the cause of the abnormality, and even automatically stop the current descent action to protect the material if necessary.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
