[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4 This utility model provides a technical solution: a multi-directionally movable laser, including a processing platform 1, a fixed plate 2 fixedly connected to the upper end of the processing platform 1, a limiting groove 3 fixedly opened on both sides of the fixed plate 2, a push rod 4 slidably connected to both sides of the limiting groove 3, an X-axis adjustment device 5 fixedly connected to both sides of one upper end of the processing platform 1, a Y-axis adjustment device 6 fixedly connected to one side of the X-axis adjustment device 5, a Z-axis adjustment device 7 fixedly connected to one side of the Y-axis adjustment device 6, and a laser 8 fixedly connected to one side of the Z-axis adjustment device 7.
[0019] In this implementation scheme, the PCB board is placed on the upper end of the fixed plate 2. Then, the push rods 4, which are slidably set on both sides, are driven by the dual-axis cylinder to bring the two PCB boards closer together. After the PCB boards are brought together, the X-axis adjustment device 5 can be used to adjust the position by translation along the X-axis. Then, the Y-axis adjustment device 6 is used to adjust the position along the Y-axis. After adjusting the distance between the X and Y axes, the Z-axis adjustment device 7 is used to adjust the direction of the Z-axis by raising and lowering. Laser printing is performed simultaneously by the lasers 8 set on both sides. This design method, through the coordinated adjustment of the X, Y and Z axes, can precisely adjust the position of the lasers 8, allowing the lasers 8 to print QR codes at different positions on the PCB board without manual adjustment, which is more convenient.
[0020] Specifically, the X-axis adjustment device 5 includes an X-axis telescopic table 9, a first fixed plate 10, a first stop 11, and a first slide rail 12. The upper end of the X-axis telescopic table 9 is fixedly connected to the first fixed plate 10, and the upper end of the first fixed plate 10 is fixedly connected to the Y-axis adjustment device 6. The upper side of the processing platform 1 is fixedly connected to the first slide rail 12, and the first stop 11 is fixedly connected to one side of the first fixed plate 10. The first stop 11 is slidably disposed inside the first slide rail 12.
[0021] In this embodiment, the X-axis telescopic platform 9 can drive the first fixed plate 10 to translate on the platform surface, thereby driving the Y-axis adjustment device 6 to translate on the X-axis. At the same time, the first fixed plate 10 can drive the first stop 11 to move when it moves through the first slide rail 12. The first stop 11 can slide and limit the movement on the inner side of one end of the first slide rail 12, making the movement of the first fixed plate 10 more stable.
[0022] Specifically, the Y-axis adjustment device 6 includes a Y-axis telescopic platform 13, a second fixed plate 14, a second stop 15, and a second slide rail 16. The second fixed plate 14 is fixedly connected to one side of the Y-axis telescopic platform 13, and the Z-axis adjustment device 7 is fixedly connected to one side of the second fixed plate 14. The second stop 15 is fixedly connected to the upper end of the second fixed plate 14, and the second slide rail 16 is fixedly connected to the upper end of the Y-axis telescopic platform 13. The second stop 15 is slidably disposed inside the second slide rail 16.
[0023] In this embodiment, the Y-axis telescopic platform 13 can drive the second fixed plate 14 to slide. After the second fixed plate 14 slides, it can drive the Z-axis adjustment device 7 to move, thereby enabling Y-axis adjustment. At the same time, the second stop 15 can slide inside one end of the second slide rail 16, which can limit the second fixed plate 14 during the sliding process, making the sliding of the second fixed plate 14 more stable.
[0024] Specifically, the Z-axis adjustment device 7 includes a Z-axis telescopic table 17 and a third fixed plate 18. The third fixed plate 18 is fixedly connected to one side of the Z-axis telescopic table 17, a laser 8 is fixedly connected to one side of the third fixed plate 18, and a positioning camera 19 is fixedly connected to one side of the laser 8.
[0025] In this embodiment, the Z-axis telescopic platform 17 can be raised and lowered to move the third fixed plate 18, allowing the laser 8 to be adjusted along the Z-axis. The positioning camera 19 can take pictures to locate the two plates, thus quickly and accurately finding the marking position.
[0026] Specifically, the surface of the fixing plate 2 is provided with debris collection holes 22, and fixing adsorption holes 21 are fixedly opened on both sides of one end surface of the fixing plate 2.
[0027] In this embodiment, an external negative pressure pump is connected to the debris collection hole 22 on the surface of the fixing plate 2. When the PCB board is placed, it can be adsorbed and fixed to a certain extent. During laser marking, small debris generated can be collected through the fixing adsorption hole 21. The existing dust collection device can be used to extract and collect the debris, which is beneficial for debris collection. In use, the two boards are placed on the upper end of the fixing plate 2. At this time, the two boards are brought together by the push rods 4 on both sides. After they are brought together, the X-axis telescopic table 9 can drive the first fixing plate 10 to move on the platform surface. The surface is translated, thereby causing the Y-axis adjustment device 6 to translate along the X-axis. Then, the Y-axis telescopic stage 13 can drive the second fixed plate 14 to slide. After the second fixed plate 14 slides, it can drive the Z-axis adjustment device 7 to move, thereby adjusting the Y-axis. After the printing position is determined, the Z-axis telescopic stage 17 can lift and lower to drive the third fixed plate 18 to move, so that the laser 8 can be adjusted along the Z-axis. This allows the lasers 8 on both sides to perform laser printing. The printing position is at the position of the fixed suction holes 21 on both sides, which facilitates the collection of debris.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
