Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a large-board laser marking device. Background Technology

[0002] A PCB, also known as a circuit board or printed circuit board, serves as the carrier of circuits and is a fundamental component of electronic products. From small appliances to large appliances, whether industrial or household, all rely on PCBs. Among similar PCB products, larger ones are generally called "large boards," and smaller ones are called "small boards," and they can be adapted to meet the assembly and design requirements of different devices.

[0003] After the basic PCB fabrication is completed, further design and processing will be carried out to implement specific functions and circuits. In order to identify the circuit board, it is generally required to mark the circuit board after the design is completed, so as to mark the circuit board model, specifications, code and other markings, so as to facilitate the identification of staff.

[0004] However, as a core component of modern electronic devices, the manufacturing process of PCBs directly affects the quality and performance of electronic products. In the PCB production process, the marking process is a crucial link for product traceability and quality control. Traditional marking processes suffer from the following technical defects: First, manual loading and unloading is not only inefficient, but operator fatigue can also lead to decreased positioning accuracy; second, large-size PCBs are prone to deformation during handling, affecting subsequent marking accuracy; third, existing equipment lacks automated material handling systems, making continuous production difficult. These problems are particularly pronounced in large-board processing scenarios: manual handling of large-size PCBs is labor-intensive, and positioning errors can easily cause laser marking position deviations, potentially damaging the circuit board surface. Furthermore, existing marking equipment generally lacks intelligent material identification and positioning systems, failing to meet the dual demands of modern intelligent manufacturing for both production efficiency and accuracy.

[0029] Figure 3 This is a complete structural schematic diagram of an embodiment of a large-plate laser marking device of this utility model. Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should be noted that, in any embodiment of this application, the "large board" refers to a PCB with a relatively large area. A large board is a non-standard sized circuit board, such as a PCB board not smaller than 30.5cm × 24.4cm.

[0032] This utility model provides an embodiment of a large-plate laser marking device, such as... Figures 1 to 3As shown, it may specifically include: a marking workbench 201, with an AGV material cart 101 at each end; two first linear modules 103 are horizontally arranged above the marking workbench 201 and the AGV material cart 101, and the lower ends of the two first linear modules 103 are connected to elastic suction cups 105 through a first lifting component 104; the marking workbench 201 is longitudinally provided with a lead screw and a slide rail, and a movable adsorption plate 202 is provided on the lead screw and the slide rail; the marking workbench 201 is also provided with a laser marking mechanism and a vision inspection mechanism 205.

[0033] During operation, one AGV material cart 101 can be used as a feeding device, and the other as a receiving device. When feeding material through the AGV material cart 101, one of its elastic suction cups 105 adsorbs the PCBs to be marked onto the AGV material cart 101, while the other set adsorbs the marked PCBs located on the moving suction plate 202. The operation is synchronized: unmarked PCBs are placed on the moving suction plate 202, while marked PCBs are moved to the AGV material cart 101 used for receiving; when the PCB to be marked is placed on the moving suction plate 202... When the moving adsorption plate 202 is activated, it will adsorb the PCB board and move it under the vision inspection mechanism 205 for detection and positioning. After the position is determined, the laser marking mechanism will be activated to mark the PCB board. After marking is completed, the moving adsorption plate 202 will move the PCB board under the first linear module 103, where it will be adsorbed by the elastic suction cup 105 used for unloading and moved to the unloading AGV material cart 101. The loading elastic suction cup 105 will then place the PCB board to be marked onto the moving adsorption plate 202.

[0034] The AGV material cart 101 refers to a material transport device with autonomous navigation capabilities, which can be implemented using magnetic strip navigation or laser navigation, and is used to automatically transport circuit boards along a fixed path. The first linear module 103 refers to a linear drive mechanism that moves horizontally, which can be implemented using a ball screw or synchronous belt drive structure, and is used to control the lateral movement range of the elastic suction cup 105. The elastic suction cup 105 refers to a vacuum adsorption device with a buffer function, which can be implemented using a silicone suction cup combined with a spring 106 structure, and is used to provide flexible contact and avoid surface indentation when gripping the circuit board. The moving adsorption plate 202 refers to a carrier platform with vacuum adsorption capabilities, which can be implemented using a porous ceramic plate or a metal plate with a vacuum cavity, and is used to fix the circuit board to prevent positional displacement during movement. The screw and slide rail form a longitudinal drive system, which can be implemented using a ball screw combined with a linear guide rail structure, and is used to precisely control the longitudinal positioning accuracy of the moving adsorption plate 202. The visual inspection mechanism 205 refers to a positioning device composed of an industrial camera and an image processing system. Specifically, it can be implemented using a CCD camera in conjunction with machine vision algorithms to identify the feature positions of circuit boards and provide feedback coordinate information.

[0035] Specifically, after the AGV material cart 101 transports the circuit board to be processed to the working position, the marking worktable 301 drives the elastic suction cup 105 to move above the material cart, and lowers it via the lifting assembly to adsorb the circuit board. The adsorbed circuit board is transferred to the surface of the moving suction plate 202, where it is fixed by vacuum adsorption. Then, the lead screw drives the moving suction plate 202 to move to the vision inspection area. The vision inspection mechanism 205 acquires images of the circuit board, calculates the offset between the actual and theoretical positions through feature matching, and feeds this information back to the control system to adjust the laser marking path. After positioning, the laser marking mechanism performs the marking operation according to the corrected coordinates. Simultaneously, another set of elastic suction cups 105 transfers the completed circuit board from the moving suction plate 202 to the receiving AGV material cart 101, achieving synchronous loading and unloading operations. The moving suction plate 202 immediately receives new circuit boards after unloading, forming a continuous operation cycle.

[0036] Compared to existing technologies, traditional manual operation requires separate handling of loading / unloading and positioning. This solution utilizes the AGV material cart 101 and linear modules to achieve automated material flow, reducing manual intervention. Conventional equipment often employs rigid clamps; this solution's dual-adsorption design of the elastic suction cup 105 and the moving adsorption plate 202 prevents damage to the circuit board surface. Existing technologies rely on manual visual positioning; this solution achieves sub-millimeter positioning accuracy through the vision inspection mechanism 205, ensuring accurate marking positions. In traditional single-line operation modes, loading / unloading requires waiting for the process to complete; this solution's dual linear modules enable parallel operation, effectively improving equipment utilization.

[0037] This application achieves automated loading and unloading and precise positioning of circuit boards, eliminating efficiency bottlenecks and accuracy errors caused by manual operation. The dual AGV material carts 101, combined with a dual linear module design, enable simultaneous feeding and receiving, improving equipment uptime. A vision positioning system automatically compensates for circuit board positional deviations, ensuring the accuracy of laser marking. An elastic adsorption mechanism keeps the circuit boards flat during transport, preventing deformation or damage caused by mechanical stress. The entire processing forms a closed loop, suitable for the high-volume processing needs of continuous production lines.

[0038] In one embodiment of this application, as Figures 1 to 3As shown, a second linear module 204 is also laterally arranged on the marking worktable 201. The laser marking mechanism and the vision inspection mechanism 205 are movably connected to the second linear module 204. The second linear module 204 refers to a precision transmission structure extending laterally along the marking worktable 201. Specifically, it can be implemented using a ball screw and a servo motor 203, with its internal guide rails and slider forming a high-precision linear motion pair. This module provides a shared motion reference for the laser marking mechanism and the vision inspection mechanism 205, ensuring their positional synchronization during movement. The laser marking mechanism refers to a component including a laser generator, a focusing lens group, and a control unit. Specifically, it can be implemented using a fiber laser and a galvanometer system to form a preset marking pattern on the PCB surface. The vision inspection mechanism 205 is a device integrating an optical lens and an image processor. Specifically, it can be implemented using an industrial camera and a machine vision algorithm, which determines the PCB positioning data through image acquisition and coordinate calculation.

[0039] Specifically, after the second linear module 204 is installed laterally along the marking worktable 201, the laser marking mechanism and the vision inspection mechanism 205 are slidably connected to the module guide rail via sliders. When the PCB board is transported to the marking station via the moving suction plate, the vision inspection mechanism 205 moves along the second linear module 204 to the inspection position, acquires the actual coordinate data of the PCB board through image acquisition, and feeds it back to the control system. Subsequently, the laser marking mechanism moves along the same module to the processing position, performs position compensation based on the visual positioning data, and performs the marking operation. After marking is completed, the vision inspection mechanism 205 moves again along the module to the re-inspection station to verify the marking quality. Since the two mechanisms share the same motion reference of the same module, the coordinate system deviation caused by the difference in the mounting base surface in the traditional split structure is avoided.

[0040] By adding a second linear module 204 laterally to the marking worktable 201, and movably connecting the laser marking mechanism and the vision inspection mechanism 205 to this module, synchronous movement control of the two in the lateral direction is achieved. The second linear module 204, as a high-precision transmission structure, allows the laser marking mechanism to make fine-tuning adjustments along the module's track, ensuring precise alignment between the marking head and the PCB board being processed. Simultaneously, the vision inspection mechanism 205 moves along the same module, quickly moving to the inspection station before marking to complete visual positioning, and performing real-time re-inspection of the marking quality after marking. This integrated, movable connection design not only saves equipment space, but more importantly, eliminates relative positional errors between mechanisms by sharing a drive module, forming a closed-loop control between the marking and inspection processes, thereby improving overall processing accuracy and automation levels. It avoids positioning errors caused by manual intervention. The vision inspection device can quickly switch working states along the same motion trajectory before and after marking, significantly improving inspection efficiency and the continuity of the marking process.

[0041] In one embodiment of this application, the laser marking mechanism and the vision inspection mechanism 205 are integrated into one unit; a servo motor 203 is connected to the end of the lead screw. The integration of the laser marking mechanism and the vision inspection mechanism 205 means that the two functional modules are integrated into a single motion unit through a shared bracket or modular structure. Specifically, a rigid connection frame can be used to maintain a fixed relative position between the vision inspection module and the laser marking head. This integration method eliminates calibration errors caused by independent movement of separate structures and shortens the connection time between visual positioning and marking actions.

[0042] The connection of the lead screw to the servo motor 203 means that the drive end of the lead screw is directly coaxially connected to the output shaft of the servo motor 203. Mechanical coupling can be achieved through a coupling or flange. The closed-loop control characteristics of the servo motor 203 enable it to monitor the rotation angle and speed of the lead screw in real time, eliminating transmission backlash through feedback adjustment, thereby improving the positioning accuracy of the moving adsorption plate.

[0043] Specifically, the integrated laser marking mechanism and vision inspection mechanism 205 are driven by the second linear module 204, simultaneously performing visual positioning and marking actions during lateral movement. After acquiring the PCB's positional deviation data, the vision inspection mechanism 205 directly transmits it to the laser marking mechanism through the rigid connection of the integrated structure, enabling it to quickly adjust the marking path. The servo motor 203 precisely controls the moving suction plate to move along the longitudinal slide rail to the target coordinates by providing real-time feedback on the lead screw's position information, avoiding the cumulative errors caused by missed steps or overshoot in traditional stepper motors.

[0044] By integrating the laser marking mechanism and the vision inspection mechanism 205 into a single structure, the two functional modules form a compact collaborative working unit in terms of spatial layout. This reduces position calibration errors and time losses caused by separate mechanism setups, thereby improving the efficiency of synchronous operation of marking and inspection. A servo motor 203 is installed at the end of the lead screw, utilizing its high-precision closed-loop control characteristics to achieve precise speed and position control of the lead screw transmission system. This avoids the cumulative errors caused by traditional motor drives, ensuring that the positioning accuracy of the moving adsorption plate 202 during the marking process reaches the micron level. The end connection of the servo motor 203 directly acts on the power input end of the lead screw, enhancing the rigidity response capability of the transmission system and further eliminating the impact of transmission backlash on positioning accuracy.

[0045] In one embodiment of this application, the AGV material cart 101 is equipped with a lifting plate 102; the lifting plate 102 is connected to a drive screw block 107, the drive screw block 107 is disposed on a vertical screw, and the vertical screw is connected to a speed-regulating drive assembly 108. The speed-regulating drive assembly 108 is mainly composed of a precision-engineered speed-regulating motor, which contains a reduction mechanism and has a speed regulation function, achieving a speed ratio of 1:3 to 1:1800; wherein, the lifting plate 102 refers to a liftable platform for carrying PCB boards, specifically made of metal plates or composite material plates, and the PCB board picking and placing height is adjusted by vertical movement. The drive screw block 107 refers to a connecting component that cooperates with the vertical screw for transmission, specifically made of copper alloy or steel sliders, and converts rotational motion into linear motion through threaded engagement. The vertical screw refers to a transmission screw arranged in the vertical direction, specifically made of ball screws or trapezoidal screws, and the height is adjusted by rotating the lifting plate 102. Speed ​​control drive components refer to drive devices used to control the speed of vertical lead screws. Specifically, they can be implemented using precision speed control motors with reduction gears, achieving precise control of lifting and lowering speeds by adjusting the output speed.

[0046] Specifically, during the operation of the AGV material cart 101, the speed-regulating drive assembly drives the vertical lead screw to rotate, causing the drive block 107 to move vertically, thereby driving the lifting plate 102 to rise and fall. By adjusting the speed of the speed-regulating drive assembly, the moving speed and target height of the lifting plate 102 can be precisely controlled. For example, when handling PCBs of different thicknesses, the lifting plate 102 can be adjusted to the corresponding height according to preset parameters, allowing the elastic suction cup 105 to accurately pick up the PCB. The rigid transmission between the vertical lead screw and the drive block 107 avoids the slippage that may occur in traditional lifting mechanisms, ensuring that the PCB remains horizontal during handling.

[0047] Through the coordinated action of the lifting plate 102, drive screw block 107, vertical screw, and speed-regulating drive assembly 108, precise control of the lifting height of the AGV material cart 101 is achieved. The lifting plate 102, serving as a platform for carrying the PCB board, is driven vertically by the transmission relationship between the drive screw block 107 and the vertical screw. The speed-regulating drive assembly 108 precisely controls the lifting speed and position of the lifting plate 102 by adjusting the rotational speed and stroke of the vertical screw. The precision-engineered speed-regulating motor and reduction mechanism used in the speed-regulating drive assembly 108 enable smooth and precise lifting across a wide range of speed ratios, thus adapting to the handling requirements of PCB boards of different thicknesses or stacked states. The combination of the drive screw block 107 and the vertical screw not only enhances the rigidity of the transmission structure but also avoids slippage or offset problems that may occur in traditional lifting mechanisms, ensuring the PCB board maintains a stable posture during transport. This structural design enables the AGV material cart 101 to be highly matched with the moving adsorption plate 202 of the marking workbench 201, thereby improving the automation level and operational accuracy of the entire marking process.

[0048] In one embodiment of this application, the elastic suction cup 105 is provided with a column, and a spring 106 is sleeved on the column. The column is a rigid support component, specifically a stainless steel cylindrical structure. It serves as the base structure of the suction cup 105, transmitting the adsorption force and maintaining the shape stability of the suction cup 105. The spring 106 is an elastic buffer element, specifically a helical compression spring. It is sleeved on the outside of the column and absorbs the impact energy when the suction cup 105 contacts the PCB through elastic deformation.

[0049] Specifically, when the elastic suction cup 105 contacts the PCB surface, the posts provide rigid support to maintain a uniform distribution of the suction force. The spring deforms according to the flatness differences of the board surface, allowing the bottom surface of the suction cup 105 to flexibly adhere to the PCB contact surface. During this process, the spring compression automatically adjusts the contact pressure of the suction cup 105 on the PCB, preventing board deformation or surface damage due to excessive local pressure. When mechanical vibration occurs during the suction process, the elastic restoring force of the spring can counteract the vibration interference, maintaining stable contact between the suction cup 105 and the PCB.

[0050] This invention solves the problems of unstable adsorption and board damage caused by rigid contact between the suction cup 105 and the PCB, achieving flexible adaptive adsorption of PCBs with different flatness, thus improving the stability of the adsorption process and the protection of the board. By incorporating a spring 106 structure on the column of the elastic suction cup 105, an elastic buffering function is achieved on the contact surface of the suction cup 105. The column, as a rigid support component, provides the basic load-bearing structure for the suction cup 105; the spring 106, through its elastic deformation characteristics, allows the suction cup 105 to automatically adjust the pressure distribution according to the flatness difference of the board when contacting the PCB surface. This elastic contact mechanism ensures effective transmission of adsorption force while avoiding surface indentations or board deformation caused by rigid contact between the suction cup 105 and the PCB, making it particularly suitable for the flexible adsorption needs of large-size PCBs. The compression and rebound characteristics of the spring 106 also absorb vibration interference during mechanical movement, improving the stability of the adsorption process.

[0051] In one embodiment of this application, the AGV material cart 101 and the marking workbench 201 are equipped with adjustable support feet at their lower ends; the AGV material cart 101, with its lower end near the support feet, is also equipped with casters with brakes. By providing adjustable support feet, the height and level of the device can be adjusted according to ground conditions, ensuring the stability of the marking workbench 201 and the AGV material cart 101 in a static state and avoiding tilting or vibration of the equipment due to uneven ground. The addition of casters with brakes near the support feet at the lower end of the AGV material cart 101 ensures flexibility during equipment movement and allows for positioning via braking, preventing displacement of the equipment during marking. The combined design of the support feet and casters achieves a balance between ease of movement and operational stability; the support feet are responsible for static support adjustment, while the casters are responsible for dynamic movement control, and their spatial arrangement effectively avoids functional interference.

[0052] In one embodiment of this application, a first housing 301 and a second housing 302 are also included; the first housing 301 is covered on the upper end of the AGV material cart 101, and the second housing 301 is covered on the upper end of the marking workbench 201; and the first housing 301 and the second housing 302 are provided with matching windows on their sides, and detachable windows are provided at the window positions.

[0053] The split-shell structure isolates and protects critical components of the equipment. The first shell 301, covering the AGV material cart 101, prevents dust contamination during material transportation, while the second shell 302, covering the marking workbench 201, isolates it from fumes generated during laser processing and external environmental interference. Side window design provides operating access while ensuring airtightness. The detachable window structure meets personnel access needs during routine maintenance while maintaining protective integrity during production. The symmetrical layout of the matching windows ensures consistent operational flow when the two shells work together. The modular design of the detachable windows allows for adjustment of opening position and size according to actual working conditions, achieving a dynamic balance between protective function and operational convenience.

[0054] In one embodiment of this application, both the first housing 301 and the second housing 302 are provided with a lighthouse 303 at their upper ends. The lighthouse 303 on the first housing 301 is electrically connected to the main control unit of the AGV material cart 101 and is used to indicate the working status of the AGV material cart 101, while the lighthouse 303 on the second housing 302 is electrically connected to the main control unit of the marking workbench 201 and is used to indicate the working status of the marking workbench 201.

[0055] By installing lighthouses 303 on two independent housings and establishing electrical connections with the corresponding main control units, real-time visual indication of the equipment's operating status is achieved. The lighthouse 303 on the first housing 301 directly reflects the feeding, receiving, and movement status of the AGV material cart 101, while the lighthouse 303 on the second housing 302 synchronously displays the positioning, marking, and detection status of the marking workbench 201. This split-type indication design allows operators to quickly distinguish the operating status of different modules, reducing the risk of misoperation due to status confusion. Through the signal transmission mechanism of the main control unit, the lighthouse 303 can accurately reflect the internal logic control status of the equipment, such as the full / empty signal of the AGV material cart 101 or the fault alarm signal of the marking workbench 201. The independent connection method avoids signal crosstalk, ensuring the reliability of status indication. The physical layout of the lighthouse 303, located at the top of the housing, conforms to ergonomic principles and facilitates observation from multiple angles.

[0056] In one embodiment of this application, the first housing 301 has a viewing window 304 and a touch screen 307 on its front side; the viewing window 304 is hinged to the first housing 301; the second housing 302 has a viewing window 304 hinged to it.

[0057] By incorporating a specially structured viewing window 304 and touchscreen 307 on the first housing 301 and the second housing 302, the challenges of human-machine interaction and equipment status monitoring during operation are solved. The viewing window 304 on the front of the first housing 301 employs a hinged structure, allowing operators to adjust its opening angle as needed. This enables direct observation of the loading and unloading status of the PCB boards inside the AGV material cart 101 during equipment operation. The hinged design also facilitates opening the viewing window 304 for internal equipment maintenance. The integrated touchscreen 307 enhances the intuitiveness of human-machine interaction, allowing operators to directly input commands or view equipment operating parameters without relying on an external control terminal. Similarly, the hinged viewing window 304 on the second housing 302 allows real-time observation of the working status of key components such as the laser marking mechanism and vision inspection mechanism 205 inside the marking workbench 201. The hinged structure also ensures convenient disassembly and repositioning of the viewing window 304 during maintenance, avoiding the operational complexity associated with disassembling the entire housing. These features together achieve the dual technical effects of making equipment operation transparent and convenient to use.

[0058] The AGV material cart 101 is also equipped with a pusher frame 305 at its front end. By setting the pusher frame 305 at the front end of the AGV material cart 101, the operator can manually push the AGV material cart 101 to assist in its movement or precise positioning. The design of the pusher frame 305 provides a physical support point for manual intervention, solving the problem that the fully automatic AGV material cart 101 cannot move flexibly in specific scenarios (such as narrow spaces, temporary position adjustments, or equipment failures). The structure of the pusher frame 305 is located at the front end, conforming to ergonomic principles, making it easy for the operator to apply force, while avoiding interference with other functional components of the AGV material cart 101, thus enhancing the controllability of the equipment while ensuring the automation process.
