[0017] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] See Figures 1 to 7This utility model provides an embodiment of a dual-station laser PCB separator, including two linear modules 1 for conveying products, a laser cutting component 2 for performing PCB separator operations, a dust extraction component 4 for removing dust generated during the cutting process, and a visual inspection component 5 for detecting the quality of the cut products. Integrating separator operation and inspection reduces equipment investment costs, while the dual-station setup reduces equipment downtime and enables efficient continuous production. In existing technologies, to achieve efficient and orderly collaborative operation of each component, the PCB separator is equipped with a control module to start and stop the equipment, set cutting parameters (such as cutting speed, power, cutting path, etc.), and select different working modes as needed. It should be noted that achieving automated production of the PCB separator through a control module is a conventional technical means, and therefore will not be elaborated upon in this embodiment.

[0019] In this embodiment, the workbench 6 is equipped with two parallel linear modules 1, each with a carrier 11 for placing products. That is, by setting up two parallel production lines, when products on one production line are undergoing laser separation, products on the other production line are simultaneously undergoing inspection, thereby reducing equipment idle time and achieving efficient continuous production. The linear modules 1 are constructed using linear motor modules to ensure stable product movement and movement accuracy, guaranteeing separation accuracy and inspection reliability.

[0020] Meanwhile, the laser cutting component 2 and the vision inspection component 5 are mounted above the two linear modules 1 via a gantry 3. Specifically, the laser cutting component 2 and the vision inspection component 5 are respectively positioned on both sides of the crossbeam 31 of the gantry 3, enabling the PCB separator to seamlessly connect with product quality inspection after completing the PCB separation operation. Furthermore, while the vision inspection component 5 is performing its inspection operation, the laser cutting component 2 continues its PCB separation operation, achieving integrated cutting and inspection functions. In addition, unlike existing technologies that rely on the movement of the gantry to drive the large-span longitudinal movement of the laser cutting component, this embodiment fixes the gantry 3 to the worktable 6, avoiding vibration and deviation caused by large movements. This provides a stable operating environment for the laser cutting component 2 and the vision inspection component 5, ensuring the accuracy and quality of the cutting and inspection processes.

[0021] Specifically, the laser cutting assembly 2 includes a generator 21 mounted on the crossbeam 31 of the gantry 3, and a laser cutting head 23 mounted on one side of the crossbeam 31 via a first moving assembly 22 and connected to the generator 21 via an optical path. The first moving assembly 22 includes a first lateral moving module 221 mounted on one side of the crossbeam 31, a laser head platform 222 slidably mounted on the first lateral moving module 221, and the laser cutting head 23 connected to the laser head platform 222 via a first vertical moving module 223, thereby enabling the laser cutting head 23 to move both laterally and vertically.

[0022] Furthermore, the laser emitted from generator 21 is reflected sequentially by multiple reflectors 211 and then focused by focusing reflector 212 to form a high-energy-density beam, which then passes vertically through the airflow of the dust collection assembly 4. Multiple reflectors 211 are housed in sealed enclosures to protect them from external dust and ensure stable laser transmission. It should be noted that the first horizontal movement module 221 and the first vertical movement module 223 also use linear motor modules to ensure stable and precise movement of the laser cutting head 23. Specifically, generator 21 is a carbon dioxide laser, which generates laser light through gas discharge excitation: its core is a sealed quartz tube filled with a mixture of carbon dioxide, nitrogen, and helium. A high-voltage electric field ionizes the gas molecules, forming plasma and generating a high-power infrared beam. The laser beam is focused after multiple reflections by multiple reflectors and projected onto the working area through focusing reflector 212, achieving high-precision PCB board cutting. Furthermore, the smoke and dust generated by laser cutting are removed by the dust collection assembly.

[0023] Furthermore, the dust collection component 4 includes an air blowing component 41 and a dust collecting component 42 respectively disposed near the lower part of the laser cutting head 23. The airflow direction of the dust collection component 4 is set perpendicular to the forward direction of the laser of the laser cutting head 23 in order to collect the smoke and dust generated during the laser cutting process.

[0024] Specifically, the air blowing component 41 and the dust collecting component 42 are arranged opposite each other, and are positioned below the focusing mirror 212 via an L-shaped connecting bracket 43. The air blowing component 41 has a row of air outlets 411 on the side facing the dust collecting component 42 to blow out a uniform airflow. The dust collecting component 42 includes a dust collecting port 421 on the side facing the air blowing component 41, and a pipe 422 for connecting to a rear-end dust collection device. The dust collected through this pipe is transported outside the device for processing. It is easy to understand that the pipe 422 is flexibly connected to the other end of the dust collecting port using a corrugated pipe (not shown in the figure) to ensure the normal operation of the dust collection component when the laser cutting head moves. The bottom surface of the air blowing component 41 and the bottom surface of the dust collecting port 421 are on the same horizontal plane. Simultaneously, the top surface 412 of the air blowing component is inclined towards this horizontal plane to ensure that the dust collecting port 421 completely covers the airflow, ensuring effective dust collection. Guide surfaces 4211 are provided at both ends of the dust collecting port 421 along its length. The two ends of the air blowing component 41 are connected to air pipe interfaces. During the laser cutting process, the smoke and dust rise and focus on the dust collection component (i.e., below the laser cutting head). At this time, the airflow from the air blowing port 411 blows the smoke and dust towards the dust collection port.

[0025] To further improve dust collection efficiency, a dust collection cover 44 is provided on the upper part of the air blowing component 41 and the dust collection port 421. A trapezoidal opening 441 is formed on the dust collection cover 44, with the lower base of the trapezoidal opening 441 positioned near the side of the air blowing component 41 and the upper base positioned near the starting end of the guide surface 4211. The trapezoidal opening not only provides space for laser operation but also facilitates dust accumulation to prevent its spread. The top surface and guide surface help guide airflow and dust, improving dust collection efficiency. By improving the working environment through the dust collection component, the laser cutting head is protected from dust interference, thereby ensuring cutting quality.

[0026] It is known that, due to the high energy characteristics of lasers, the airflow of the vacuuming component does not affect them.

[0027] Furthermore, the vision inspection component 5 is mounted on the other side of the crossbeam 31 via a second moving component 51. The second moving component 51 includes a second lateral moving module 511 mounted on the other side of the crossbeam 31 and a second vertical moving module 512 mounted on the second lateral moving module 511. The vision camera 52 of the vision inspection component 5 is mounted on the slide table 5121 of the second vertical moving module 512 to ensure stable vertical and lateral movement of the vision camera.

[0028] In addition, the vision inspection component 5 also includes a lighting lamp 54 mounted on the slide table 5121 via a bracket 53 and surrounding the lens of the vision camera 52, providing uniform and sufficient light to the vision camera and ensuring the clarity of the captured images. During actual inspection, the vision camera, equipped with existing image processing algorithms, can quickly detect defects on the product's cut edges, such as burrs, unevenness, and dimensional deviations, improving inspection efficiency and accuracy.

[0029] Furthermore, the depaneling machine is equipped with transmission components at both ends. These components include an input for loading and an output for unloading. The input is positioned towards the laser cutting component 2, and the output is positioned towards the vision inspection component 5, according to the product's processing direction. The transmission components can be operated by robots (such as six-axis robots or spider robots), reducing manual intervention and increasing the level of production automation.

[0030] In summary, the dual-station laser PCB separator provided by this utility model reduces equipment investment costs by integrating PCB separation and inspection into a fixed gantry. Simultaneously, the dual-station setup enables seamless integration of processing and inspection operations. Furthermore, product movement compensates for the multi-directional positioning requirements of PCB separation and inspection, reducing equipment downtime and achieving efficient continuous production. In addition, a dust collection component collects the fumes generated during cutting, preventing them from adhering to the laser cutting head, ensuring cutting quality while improving the working environment.
