Drilling is one of the key processes in PCB production, and its main purpose is to provide through-hole paths for conductive connections on the circuit board to achieve electrical connections between multi-layer circuits.

[0003] Existing PCB drilling equipment mostly uses belt drive or gear and rack drive, which has problems such as insufficient positioning accuracy and easy wear leading to cumulative errors. In addition, traditional worktables lack an integrated chip collection system, and relying solely on external dust collection devices can easily affect processing accuracy due to chip accumulation. At the same time, frequent cleaning shutdowns seriously affect production efficiency. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a linearly driven PCB drilling device includes an operation board 1. A linear drive frame 2 is fixedly connected to the top of the operation board 1. A mounting plate 6 is slidably connected to one side of the linear drive frame 2. A drilling component 8 is fixedly mounted on one side of the mounting plate 6. A translation component is provided inside the linear drive frame 2 to drive the drilling component 8 to move. A support plate 15 is slidably connected to the top of the operation board 1. A feeding component is provided inside the operation board 1 to drive the support plate 15 to move. A guide is provided on the top of the support plate 15. A support mesh 17 is fixedly connected between the inner walls of the flow channel 16 and the guide channel 16. A sliding groove 18 is provided on one side of the bearing plate 15. The guide channel 16 communicates with the sliding groove 18. A slag removal box 19 is provided between the inner walls of the sliding groove 18. A slot 20 is provided on one side of the slag removal box 19. A locking component is provided inside the bearing plate 15. The locking component is used to lock the slag removal box 19. A scale pattern 28 is provided on the outer side of the linear drive frame 2. An observation window 9 is provided inside the mounting plate 6. A pointer 10 is fixedly connected to one side of the mounting plate 6. The tip of the pointer 10 corresponds to the scale pattern 28.

[0023] When using a linear drive PCB drilling machine, first connect the machine to an external power source to power it on. Then, the linear drive frame 2 on the machine's operation panel 1 drives the mounting plate 6 and the drilling component 8 to move precisely along the scale 28 through the internal translation component. The operator calibrates the drilling position by aligning the observation window 9 and the pointer 10 with the scale 28. At the same time, the feeding component pushes the support plate 15 (the PCB board on top of the support plate 15 is fixed by an external positioning structure to ensure stability during processing) to move laterally to feed the PCB board. The debris generated during drilling falls into the guide groove 16 through the support screen 17 and enters the detachable slag removal box 19 through the slide 18. The slag removal box 19 is quickly loaded and unloaded through the cooperation of the slot 20 and the locking component, completing the integrated operation of automated drilling and waste collection.

[0024] like Figures 1-4 As shown, the translation assembly includes a linear groove 3, which is opened on one side of the linear drive frame 2. A translation screw 4 is rotatably connected between the inner walls of the linear groove 3. A translation screw block 7 is threadedly connected to the outer side of the translation screw 4. One side of the translation screw block 7 is fixedly connected to the mounting plate 6. A translation motor 5 is fixedly installed on one side of the linear drive frame 2. The output end of the translation motor 5 extends into the interior of the linear groove 3 and is fixedly connected to the translation screw 4.

[0025] When the translation motor 5 starts, it drives the translation screw 4 to rotate in the linear groove 3. The translation thread block 7, which is threadedly engaged with the translation screw 4, moves linearly along the linear groove 3, thereby driving the fixedly connected mounting plate 6 and drilling component 8 to move precisely along the linear drive frame 2, realizing the longitudinal adjustment of the drilling position.

[0026] like Figures 1-4 As shown, the feeding assembly includes a feeding trough 11, which is located at the top of the equipment operation plate 1. A feeding screw 12 is rotatably connected between the inner walls of the feeding trough 11. A moving block 14 is threadedly connected to the outer side of the feeding screw 12. The top of the moving block 14 is fixedly connected to the support plate 15. A feeding motor 13 is fixedly installed on one side of the equipment operation plate 1. The output end of the feeding motor 13 extends into the interior of the feeding trough 11 and is fixedly connected to the feeding screw 12. A guide plate 26 is fixedly connected above the feeding trough 11 and at the top of the equipment operation plate 1. A guide groove 27 is opened inside the support plate 15. The outer side of the guide plate 26 is slidably connected to the inner wall of the guide groove 27.

[0027] The feeding motor 13 drives the feeding screw 12 to rotate in the feeding groove 11, causing the threaded moving block 14 to drive the bearing plate 15 to move horizontally along the feeding groove 11; at the same time, the guide plate 26 slides with the guide groove 27 on the bearing plate 15 to ensure that the PCB board maintains stable linear motion during the feeding process and achieves precise feeding and positioning.

[0028] like Figures 1-4 As shown, the locking assembly includes a locking cavity 21, which is opened inside the support plate 15. A slide plate 22 is slidably connected between the inner walls of the locking cavity 21. A locking block 23 is fixedly connected to one side of the slide plate 22. One end of the locking block 23 extends into the inside of the locking groove 20. A spring 24 is fixedly connected between the slide plate 22 and the inner wall of the locking cavity 21. A lever 25 is fixedly connected to one side of the slide plate 22. One end of the lever 25 extends to the outside of the support plate 15.

[0029] When the slag removal box 19 is inserted into the slide groove 18, the locking block 23 is pushed by the elastic force of the spring 24 to push the slide plate 22, so that the locking block 23 automatically locks into the slot 20 of the slag removal box 19 to achieve locking; when disassembly is required, the outer pull rod 25 drives the slide plate 22 to compress the spring 24, so that the locking block 23 is disengaged from the slot 20, and the slag removal box 19 can be taken out to complete the quick cleaning.

[0030] This utility model provides a linear drive PCB drilling device. The specific working principle is as follows: After the device is powered on, the translation motor 5 drives the translation screw 4 to rotate, which drives the translation thread block 7 and the mounting plate 6 to move precisely along the linear drive frame 2. The operator can achieve drilling positioning by observing the window 9 and the index 10 in conjunction with the scale 28. At the same time, the feeding motor 13 drives the feeding screw 12 to rotate, which causes the moving block 14 to drive the bearing plate 15 to be fed smoothly along the guide plate 26, completing the precise feeding of the PCB board. The debris generated during the drilling process falls into the guide groove 16 through the support screen 17, and enters the slag removal box 19 through the slide 18. The slag removal box 19 is quickly loaded and unloaded by the automatic engagement of the clamping block 23 pressed by the spring 24 and the clamping groove 20, realizing the automated operation of drilling and waste collection.

[0031] 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.
