Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, and in particular to a laser window opening device for PCB boards with alternating feeding. Background Technology

[0002] A circuit board, or PCB (Printed Circuit Board), is an indispensable component in modern electronic devices, carrying the electrical connections and signal transmissions between electronic components. A crucial step in PCB manufacturing is applying a solder mask layer to the board surface to protect the circuitry and prevent short circuits in component leads. This solder mask typically consists of a layer of solder resist ink (often referred to as green solder mask) applied to the etched circuit board using a specific process. However, to meet specific application requirements, such as heat dissipation and contact, the solder mask layer needs to be removed at certain soldering locations; this step is called "windowing."

[0003] For example, the utility model patent with patent authorization announcement number CN214256767U discloses a solder resist opening device for processing solder resist opening on circuit boards. The solder resist opening device includes: a frame, a laser main body mechanism, and a feeding mechanism. The frame is provided with a processing station. The laser main body mechanism is movable to the frame and is located above the processing station. The laser main body mechanism includes multiple laser processing heads, and the light outlet of the laser processing heads is set facing the processing station. The feeding mechanism is located on the frame and is used to transport the circuit board, thereby improving the solder resist opening efficiency of the circuit board and enhancing the circuit board's effectiveness.

[0004] Based on the search of the aforementioned patent grant announcement numbers, and considering their shortcomings, the following was found:

[0005] Existing PCB board windowing equipment has a single loading mechanism. After completing the initial loading step, the equipment must go through a complete processing cycle, including using laser technology to precisely open the PCB board until the entire process is completed and the opened PCB board is successfully unloaded before the next round of loading can begin. This continuous and non-parallel operation mode significantly restricts the overall processing speed and production efficiency of the equipment, making it difficult to fully realize its capacity potential in a fast-paced, high-volume production environment.

[0044] Please see the appendix Figures 1 to 3 This utility model provides a laser windowing device for PCB boards with alternating loading, comprising: a base 1, on which a first loading / unloading station, a second loading / unloading station, a first processing station, and a second processing station are provided; a laser windowing mechanism 4, which includes a laser module 45 located above the base 1, the laser module 45 reciprocating between the first processing station and the second processing station; a first loading / unloading mechanism 2, which includes a first loading / unloading platform 21 slidably disposed on the base 1, the first loading / unloading platform 21 reciprocating between the first loading / unloading station and the first processing station; and a second loading / unloading mechanism 3, which includes a second loading / unloading platform 31 slidably disposed on the base 1, the second loading / unloading platform 31 reciprocating between the second loading / unloading station and the second processing station; wherein the first loading / unloading platform 21 and the second loading / unloading platform 31 are both used to carry and position PCB boards, and the laser windowing mechanism 4 is used to perform a preset laser windowing operation on the PCB board located at the first processing station or the second processing station.

[0045] In this embodiment, by setting up two loading / unloading stations (first and second) and two processing stations (first and second), the function of alternating loading and processing is realized. When the first loading / unloading platform 21 sends a PCB board to the first processing station for window opening, the second loading / unloading platform 31 can simultaneously send another PCB board with completed window opening to the second loading / unloading station to wait for unloading and reloading. After the PCB board on the first loading / unloading platform 21 is processed, the first loading / unloading platform 21 returns to the first loading / unloading station to remove another PCB board. At the same time, the second loading / unloading platform 31 sends the waiting PCB board to the second processing station for window opening. When one station is performing laser window opening processing, the other station can simultaneously perform loading / unloading operations. This alternating loading method significantly improves the overall processing speed and production efficiency of the equipment.

[0046] Specifically, in the initial state of operation of the laser windowing device in this embodiment, the first loading / unloading platform 21 is located at the first loading / unloading station, carrying and positioning a PCB board to be processed; the second loading / unloading platform 31 is located at the second loading / unloading station, similarly carrying and positioning another PCB board to be processed, while the laser windowing mechanism 4 is in standby mode. In the first cycle of operation of the laser windowing device in this embodiment, the first loading / unloading platform 21 moves the PCB board to the first processing station, and the laser windowing mechanism 4 begins laser windowing processing on the PCB board at the first processing station. At the same time, the second loading / unloading platform 31 remains stationary, waiting for the next action. In the second cycle of operation of the laser windowing device in this embodiment, after the PCB board at the first processing station is processed, the first loading / unloading platform 21 returns to the first loading / unloading station, ready to remove the next PCB board; simultaneously, the second loading / unloading platform 31 moves the PCB board to the second processing station, and the laser windowing mechanism 4 begins laser windowing processing on the PCB board at the second processing station. The alternation of the first and second cycles realizes alternating operation and continuous production between the two stations.

[0047] For further details, please refer to Figures 4 to 9 The laser window opening mechanism 4 includes a mounting frame 41, on which a linear motion module 42 is mounted. The stator of the linear motion module 42 is connected to the mounting frame 41, and the mover of the linear motion module 42 is connected to the laser module 45. The mover of the linear motion module 42 drives the laser module 45 to move in a second direction, so that the laser module 45 moves above the first processing station or above the second processing station. The light emission direction of the laser module 45 is downward. Optionally, the linear motion module 42 can be a linear motor. In the initial state, the laser module 45 of this embodiment is connected to the mounting frame 41 through the linear motion module 42 and is located at the first processing station or the second processing station. When the PCB board at the first processing station needs to be processed, the control system sends a command to the linear motion module 42, causing its mover to move the laser module 45 above the first processing station. Similarly, when the PCB board at the second processing station needs to be processed, the laser module 45 moves above the second processing station. After the laser module 45 reaches the designated position, the control system activates the laser module 45 to perform a laser windowing operation. The laser module 45's output port is set downwards to ensure that the laser can accurately irradiate the PCB board. After completing the operation at one processing station, the laser module 45 moves to the next processing station.

[0048] Specifically, the movement direction of the laser module 45 and the movement directions of the first loading / unloading platform 21 and the second loading / unloading platform 31 are both horizontal, and the movement path of the first loading / unloading platform 21 is parallel to the movement path of the second loading / unloading platform 31, while the movement path of the laser module 45 is perpendicular to the movement paths of the first loading / unloading platform 21 and the second loading / unloading platform 31.

[0049] Furthermore, the laser window opening mechanism 4 also includes a mounting plate 43 and a dust collection component 46. The mounting plate 43 is connected to the moving part of the linear motion module 42. The laser module 45 and the dust collection component 46 are both mounted on the mounting plate 43, and the air intake of the dust collection component 46 is set downwards.

[0050] It is understandable that a large amount of smoke and debris is generated during the laser windowing process on PCB boards. If this smoke and debris are not cleaned up in time, it will not only pollute the working environment but may also damage the laser and PCB board, reducing processing quality and equipment lifespan. To address this, in this embodiment, the suction port of the dust extraction component 46 is positioned downwards, directly targeting the smoke and debris generated during the laser windowing process. When the laser module 45 performs the laser windowing operation, the dust extraction fan starts, sucking in the smoke and debris through the dust extraction component 46, thus achieving real-time cleaning of the smoke and debris during the laser windowing process and effectively protecting the working environment and processing quality of the PCB board windowing process. The mounting plate 43 serves as a common carrier for the laser module 45 and the dust extraction component 46, connected to the moving part of the linear motion module 42 to ensure that both can move synchronously. In one possible working process, the linear motion module 42 receives a command and moves the mounting plate 43, laser module 45, and dust collection component 46 to above the first or second processing station. The laser module 45 begins to perform laser windowing operation, and at the same time, the dust collection component 46 starts. The suction port of the dust collection component 46 is aligned with the processing area to absorb the generated smoke and debris in real time. After the laser windowing operation is completed, the laser module 45 stops working, and the dust collection component 46 continues to run for a period of time to ensure that all smoke and debris are completely cleaned. Then, the linear motion module 42 moves the mounting plate 43, laser module 45, and dust collection component 46 to the next processing station.

[0051] Furthermore, the areas of the first and second processing stations are the same size. The dust collection assembly 46 includes at least a first suction hood 461, a second suction hood 462, and a third suction hood 463. The lengths of the first suction hood 461, the second suction hood 462, and the third suction hood 463 in the direction of motion of the laser module 45 are the same as the lengths of the areas of the first and second processing stations in the direction of motion of the laser module 45. The first suction hood 461, the second suction hood 462, and the third suction hood 463 are on the upper part of the base 1. The components are evenly arranged along the movement direction of the first loading / unloading platform 21 and the second loading / unloading platform 31. The second suction hood 462 is located between the first suction hood 461 and the third suction hood 463. The suction port of the second suction hood 462 is set directly downwards. The suction ports of the first suction hood 461 and the third suction hood 463 are set downwards and inclined towards the second suction hood 462. The first suction hood 461, the second suction hood 462, and the third suction hood 463 are respectively connected to the dust collection fan through the first pipe, the second pipe, and the third pipe.

[0052] In this embodiment, the dust collection assembly 46 includes a first suction hood 461, a second suction hood 462, and a third suction hood 463, which are connected to a dust collection fan through their respective pipes. When the dust collection fan receives a start command, it starts working. Airflow enters the first suction hood 461, the second suction hood 462, and the third suction hood 463 through the first pipe, the second pipe, and the third pipe, respectively. The air inlets of the first suction hood 461 and the third suction hood 463 face downward and are inclined towards the second suction hood 462, which can capture smoke and debris diffused from both sides of the area of ​​the first or second processing station. The air inlet of the second suction hood 462 faces directly downward and is aimed directly at the center of the area of ​​the first or second processing station, capturing the main smoke and debris. The dust collection fan transports the captured smoke and debris to a dust collection device through pipes for further processing.

[0053] Furthermore, the laser module 45 includes several lasers with their light output ports facing downwards. These lasers are arranged in a straight line and uniformly in the second direction. Parallel processing by multiple lasers can significantly shorten processing time and improve production efficiency. It should be noted that the illumination coverage area of ​​the laser module 45 should be greater than or equal to the area of ​​the common area of ​​the first and second processing stations. Therefore, when the laser module 45 is located above the first or second processing station, it can completely cover the PCB board within that area.

[0054] Furthermore, the laser windowing mechanism 4 also includes a positioning CCD camera 44 mounted on the mounting bracket 41. The positioning CCD camera 44 is used to photograph and position the PCB board located at the first and second processing stations. Understandably, the positioning CCD camera 44 captures images of the PCB board and transmits them to the control system. The control system uses image processing algorithms to analyze and process the images to determine the position and orientation of the PCB board. Then, the laser windowing mechanism 4 adjusts its processing position based on the positioning results to ensure that the laser beam can be accurately aligned with the target windowing area.

[0055] Furthermore, the first loading / unloading mechanism 2 includes a first linear motor 22 mounted on the base 1, with the stator of the first linear motor 22 connected to the base 1 and the mover of the first linear motor 22 connected to the first loading / unloading platform 21; the second loading / unloading mechanism 3 includes a second linear motor 32 mounted on the base 1, with the stator of the second linear motor 32 connected to the base 1 and the mover of the second linear motor 32 connected to the second loading / unloading platform 31. In this embodiment, the first linear motor 22 and the second linear motor 32 are used to drive the first loading / unloading platform 21 and the second loading / unloading platform 31 to reciprocate, respectively, to realize the rapid transfer of the PCB board between the first loading / unloading station, the second loading / unloading station, the first processing station, and the second processing station.

[0056] For further details, please refer to Figures 10 to 12 The first loading / unloading platform 21 includes a first horizontal moving plate 211, a first height adjustment component 212, and a first bearing positioning plate 213. The first horizontal moving plate 211 is connected to the upper side of the mover part of the first linear motor 22. The first bearing positioning plate 213 is connected to the upper side of the first horizontal moving plate 211 through the first height adjustment component 212. The first height adjustment component 212 is used to adjust the height difference between the first bearing positioning plate 213 and the first horizontal moving plate 211. The first bearing positioning plate 213 is used to support and position the PCB board. It should be noted that the second loading / unloading platform 31 has the same structure as the first loading / unloading platform 21.

[0057] Optionally, the first height adjustment component 212 includes: a first vertical guide rail 2121 and a first vertical slider 2122, wherein the first vertical slider 2122 is slidably connected to the first vertical guide rail 2121 in the vertical direction; wherein the first vertical guide rail 2121 is disposed on the upper side of the first horizontal moving plate 211, and the first vertical slider 2122 is disposed on the lower side of the first bearing positioning plate 213, or the first vertical guide rail 2121 is disposed on the lower side of the first bearing positioning plate 213, and the first vertical slider 2122 is disposed on the upper side of the first horizontal moving plate 211. Preferably, the first height adjustment assembly 212 further includes: a first drive cylinder 2123, a first tilting slider 2124, and a second tilting slider 2125. The first tilting slider 2124 is slidably connected to the upper side of the first horizontal moving plate 211, and the second tilting slider 2125 is fixedly connected to the lower side of the first bearing positioning plate 213. The fixed end of the first drive cylinder 2123 is connected to the first horizontal moving plate 211, and the telescopic end of the first drive cylinder 2123 is connected to the first tilting slider 2124. The upper side of the first tilting slider 2124 is provided with a first tilting surface with gradually changing height, and the lower side of the second tilting slider 2125 is provided with a second tilting surface that corresponds to and fits against the first tilting surface. The first tilting surface and the second tilting surface are slidably connected. The first drive cylinder 2123 is used to drive the first tilting slider 2124 to move in the direction of the height change of the first tilting surface, so that the second tilting slider 2125 drives the first bearing positioning plate 213 to rise or fall. Preferably, the height of the first inclined surface gradually decreases from the first loading / unloading station towards the first processing station. The first driving cylinder 2123 is disposed on the side of the first inclined slider 2124 near the first loading / unloading station. Thus, when the telescopic end of the first driving cylinder 2123 extends, the second inclined slider 2125 is raised by the first inclined slider 2124; when the telescopic end of the first driving cylinder 2123 shortens, the second inclined slider 2125 descends along the first inclined surface. It can be understood that, in this embodiment, the sliding connection between the first vertical guide rail 2121 and the first vertical slider 2122 provides the first bearing positioning plate 213 with freedom of movement in the vertical direction, while the cooperation of the first driving cylinder 2123, the first inclined slider 2124, and the second inclined slider 2125 enables precise adjustment of the height of the first bearing positioning plate 213. In the initial state, the telescopic end of the first drive cylinder 2123 is in the retracted state, the first tilting slider 2124 and the second tilting slider 2125 are kept relatively stationary by the contact of the tilted surfaces, and the first bearing positioning plate 213 is located at the initial height position.When the height of the first bearing positioning plate 213 needs to be adjusted, the control system activates the first drive cylinder 2123. The telescopic end of the first drive cylinder 2123 begins to extend and retract, driving the first tilting slider 2124 to move in the direction of the height change of the first tilting surface. Since the first tilting surface and the second tilting surface are correspondingly fitted and slidably connected, the movement of the first tilting slider 2124 is converted into the lifting or lowering movement of the second tilting slider 2125 and the first bearing positioning plate 213. When the first bearing positioning plate 213 reaches the target height, the control system stops the operation of the first drive cylinder 2123 and locks its position to maintain the stability of the first bearing positioning plate 213. Preferably, the first tilting slider 2124 is located at the middle position of the first horizontal moving plate 211, the second tilting slider 2125 is located at the middle position of the first bearing positioning plate 213, and the first vertical guide rail 2121 and the first vertical slider 2122 are respectively located at the four corners of the first horizontal moving plate 211 and the first bearing positioning plate 213. In this embodiment, by positioning the first tilting slider 2124 and the second tilting slider 2125 at the center of the first horizontal moving plate 211 and the first bearing positioning plate 213, the smooth lifting or lowering of the first bearing positioning plate 213 can be achieved more effectively. Meanwhile, the design of the first vertical guide rail 2121 and the first vertical slider 2122 at the four corners provides stable support, preventing the first bearing positioning plate 213 from tilting or swaying during height adjustment.

[0058] Furthermore, the upper side of the first bearing positioning plate 213 is provided with a plurality of first adsorption holes, and the first bearing positioning plate 213 has a first negative pressure chamber connected to the first adsorption holes. The first negative pressure chamber is connected to the vacuuming equipment through an air pipe. It should be noted that the second bearing positioning plate has the same structure as the first bearing positioning plate 213. When the vacuuming equipment is started, the air in the negative pressure chamber is extracted through the air pipe to form a negative pressure environment. Due to the effect of atmospheric pressure, the adsorption holes on the first bearing positioning plate 213 or the second bearing positioning plate will generate an adsorption force on the PCB board, tightly adhering the PCB board to it.
