[0001] This utility model relates to the field of PCB board processing technology, specifically a manual laser marking machine. Background Technology
[0002] In modern electronics manufacturing, PCBs (Printed Circuit Boards) serve as fundamental components of electronic devices, bearing the crucial responsibility of connecting and transmitting electrical energy and signals. To improve production efficiency and product traceability, an increasing number of manufacturers are laser-engraving QR codes on PCBs, thus requiring laser-engraving machines.
[0003] Existing manual laser marking machines are not convenient for automatically receiving and positioning PCB boards after they are placed on the conveyor belt. The position between the PCB board and the laser marking machine is prone to deviation, resulting in incorrect laser marking and insufficient pass rate.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a manual laser marking machine. Utility Model Content

[0010] Furthermore, the position adjustment assembly also includes a movable sleeve, which is fitted on the outer side of the lead screw, and the movable sleeve is slidably connected to the inner wall of the fixed frame.
[0011] Furthermore, the position adjustment assembly also includes a cylinder and a piston rod. The cylinder is installed on the outer side of the movable sleeve, and a piston rod is provided on the front side of the cylinder. The piston rod is bolted to the laser marking machine.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figure 1 As shown, a manual laser marking machine includes a support base 1, a laser marking machine 6, and a PCB board limiting assembly 9. A position adjustment assembly 5 is installed on the upper rear side of the support base 1, and the laser marking machine 6 is installed in front of the position adjustment assembly 5. A laser marking head 7 is fixed to the lower side of the laser marking machine 6. A support rod 2 is fixed on the upper front side of the support base 1, and a mounting frame 3 is fixed on the upper side of the support rod 2. A conveyor belt 4 is arranged inside the mounting frame 3, and the conveyor belt 4 is positioned between the laser marking machine 6 and the laser marking head 7. An industrial camera 10 is installed on the lower right side of the mounting plate 8 below the head 7, and a display screen 11 is installed on the right side of the fixing frame 501. The operator manually places the PCB board onto the conveyor belt 4, so that the conveyor belt 4 can move the PCB board and feed the PCB board to the area below the laser marking head 7. The laser marking head 7 on the lower side of the laser marking machine 6 is used to laser mark the PCB board. The industrial camera 10 can identify and detect the laser-marked PCB board to ensure that the PCB board is correctly marked.
[0023] like Figure 3As shown, the position adjustment assembly 5 includes a fixed frame 501, a drive motor 502, and a lead screw 503. The drive motor 502 is installed inside the lower part of the fixed frame 501, and the lead screw 503 is provided on the upper side of the drive motor 502. The position adjustment assembly 5 also includes a movable sleeve 504, which is sleeved on the outer side of the lead screw 503. The movable sleeve 504 is slidably connected to the inner wall of the fixed frame 501. The position adjustment assembly 5 also includes a cylinder 505 and a piston rod 506. The cylinder 505 is installed on the outer side of the movable sleeve 504, and the piston rod 506 is provided on the front side of the cylinder 505. 6. The piston rod 506 is bolted to the laser marking machine 6. The drive motor 502 facilitates the rotation of the lead screw 503, which in turn drives the outer moving sleeve 504 of the lead screw 503 to move up and down. This allows the moving sleeve 504 to drive the cylinder 505, piston rod 506, and laser marking machine 6 to move up and down, thereby adjusting the laser marking head 7 to a suitable focusing height. The cylinder 505 and piston rod 506 facilitate the adjustment of the front and rear positions of the laser marking machine 6, allowing the laser marking head 7 to be positioned above the laser marking position on the PCB board. This is suitable for PCB boards of different sizes.
[0024] like Figures 1-2 As shown, a mounting plate 8 is installed on the outer right side of the laser marking machine 6, and a PCB board limiting assembly 9 is installed on the lower left side of the mounting plate 8. The PCB board limiting assembly 9 includes a hydraulic lifting rod 901, a lifting plate 902, an electric push rod 903, a limiting baffle 904, a connecting plate 905, a telescopic rod 906, and a limiting side plate 907. The lower end of the hydraulic lifting rod 901 is fixed to the lifting plate 902, and an electric push rod 903 is installed on one side of the lifting plate 902. One end of the electric push rod 903 is fixed to the limiting baffle 904, and the front and rear sides of the limiting baffle 904 are bolted to the connecting plate 905. A telescopic rod 906 is installed on the inner side of the connecting plate 905, and one end of the telescopic rod 906 is fixed to the limiting baffle 904. The limiting baffle 904 is provided with two There are two limiting baffles 904 and 905 are slidably connected. The extension and retraction of the electric push rod 903 facilitates the movement of the limiting baffle 904, so that the PCB board intercepted on one side of the limiting baffle 904 can be located below the laser marking position of the laser marking head 7. This is suitable for PCB boards of different sizes. The hydraulic lifting rod 901 facilitates the lifting of the lifting plate 902, so that the lifting plate 902 and the limiting baffle 904 can slide on the upper side of the moving conveyor belt 4. The limiting baffle 904 can intercept and limit the PCB board. The two telescopic rods 906 facilitate the extension and retraction of the position of the two limiting side plates 907, so that the two limiting side plates 907 can position the PCB board on one side of the limiting baffle 904, which is convenient for subsequent stable laser marking.
[0025] In summary, as Figures 1-3As shown, before use, the manual laser marking machine can be driven by the drive motor 502 to rotate the lead screw 503, which in turn drives the outer moving sleeve 504 of the lead screw 503 to move up and down. This allows the moving sleeve 504 to drive the cylinder 505, piston rod 506, and laser marking machine 6 to move up and down, adjusting the laser marking head 7 to a suitable focusing height. Then, the cylinder 505 and piston rod 506 are used to adjust the front and rear positions of the laser marking machine 6 so that the laser marking head 7 can be positioned above the laser marking position on the PCB board. Then, the extension and retraction of the electric push rod 903 pushes the position of the limiting baffle 904 so that the PCB board subsequently intercepted by the limiting baffle 904 can be positioned below the laser marking position of the laser marking head 7. This is suitable for PCB boards of the current size.
[0026] In operation, the operator first manually places the PCB board onto the conveyor belt 4, allowing the conveyor belt 4 to move the PCB board and feed it to below the laser marking head 7. Then, the hydraulic lifting rod 901 drives the lifting plate 902 to rise and fall, allowing the lifting plate 902 and the limit baffle 904 to slide on the upper side of the moving conveyor belt 4. The limit baffle 904 then intercepts and limits the PCB board, causing the conveyor belt 4 to stop running. Next, the two telescopic rods 906 extend and retract to adjust the position of the two limit side plates 907, allowing the two limit side plates 907 to position the PCB board on one side of the limit baffle 904. Finally, the laser marking head 7 under the laser marking machine 6 laser-marks the PCB board. After marking, the PCB board limit component 9 rises, the conveyor belt 4 continues to run and feed the PCB board, and the industrial camera 10 identifies and detects the laser-marked PCB board to ensure correct marking. This completes the operation of the manual laser marking machine.
