[0026] 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.

[0027] This utility model embodiment provides a PCB circuit board slitting machine, such as Figures 1-7 As shown, it includes a worktable 1 and a positioning block 4; the positioning block 4 is installed on the top of the worktable 1, and a circuit board 3 is placed inside the positioning block 4; a first moving component 2 is installed on one side of the top of the worktable 1, a second moving component 7 is installed on the top of the first moving component 2, and a cylinder 11 is installed at the front end of the second moving component 7; a servo motor 10 is installed at the front end of the cylinder 11, a milling cutter 12 is installed at the bottom end of the servo motor 10, a dust suction clamping structure 8 is provided at the rear end of the worktable 1, an auxiliary structure 6 is provided on one side of the bottom end of the second moving component 7, and a guide rail 5 is fixed on the other side of the top of the worktable 1.

[0028] In a further preferred embodiment of this utility model, such as Figures 1-7As shown: The vacuum clamping structure 8 includes a negative pressure fan 801, a filter box 802, a diverter pipe 803, a throttle valve 804, a negative pressure chamber 805, a connecting pipe 806, a suction head 807, filter cotton 808, and a main suction pipe 809. The negative pressure fan 801 is installed at the rear end of the workbench 1. The main suction pipe 809 is installed on one side of the negative pressure fan 801. The filter box 802 is installed at one end of the main suction pipe 809. Filter cotton 808 is installed on one side inside the filter box 802. A connecting pipe 806 is installed at the top of the filter box 802, and a suction head 807 is installed at the bottom of the connecting pipe 806. A diversion pipe 803 is installed at one end of the main suction pipe 809, and a throttle valve 804 is installed at the top of the diversion pipe 803. A negative pressure chamber 805 is opened inside the workbench 1, and a suction hole 9 is opened at the top of the negative pressure chamber 805. The rear end of the suction head 807 is fixed to the front end of the servo motor 10, and one end of the diversion pipe 803 is connected to one side of the negative pressure chamber 805.

[0029] Specifically, in this embodiment: when cutting the circuit board 3, the circuit board 3 is placed inside the positioning block 4 for positioning. After the circuit board 3 is positioned, the negative pressure fan 801 is started. After the negative pressure fan 801 is started, it will generate suction. At this time, the suction of the diverter pipe 803 can be adjusted by setting the negative pressure chamber 805. After adjustment, the inside of the negative pressure chamber 805 will be evacuated. As the air inside the negative pressure chamber 805 is extracted, a negative pressure will be generated, thereby adsorbing the circuit board 3 through the suction hole 9, fixing it to the top of the workbench 1 to complete the clamping and limiting work. After the circuit board 3 is clamped, the external power supply is started. The servo motor 10 drives the milling cutter 12 to rotate. While the milling cutter 12 is rotating, it moves according to the pre-set program on the computer, thereby cutting the circuit board 3. When the cutting generates debris, the suction force generated by the negative pressure fan 801 is transmitted to the connecting pipe 806 through the main suction pipe 809. Then, the connecting pipe 806 sucks up the debris through the suction head 807, causing the debris to enter the filter box 802. After being filtered by the filter cotton 808, the debris is left inside the filter box 802 for easy cleaning, thus completing the collection of waste debris. This achieves the collection of waste debris during the clamping of the circuit board 3.

[0030] In a further preferred embodiment of this utility model, such as Figures 1-7As shown: Auxiliary structure 6 includes guide block 601, mounting block 602, locking block 603, locking groove 604, bristles 605, ball bearings 606, and mounting groove 607. Guide block 601 is fixed to one side of the bottom of the second moving component 7. Mounting blocks 602 are fixed to both sides of guide block 601. The mounting block 602 has a locking groove 604 inside, and the locking block 603 is installed inside the locking groove 604. Bristles 605 are installed at the bottom of the locking block 603. The mounting groove 607... 07 is located at the bottom of the guide block 601. The mounting groove 607 is equipped with a ball bearing 606. The top view cross-sectional area of ​​the slot 604 is larger than the top view cross-sectional area of ​​the block 603. The block 603 and the slot 604 form an engaging structure. There are two sets of blocks 603. The two sets of blocks 603 are symmetrically distributed on both sides of the guide block 601. The ball bearing 606 is installed inside the mounting groove 607. The mounting groove 607 and the ball bearing 606 form a rolling connection.

[0031] Specifically, in this embodiment, when the second moving component 7 moves, it drives the guide block 601 to move inside the guide rail 5. At this time, the ball bearing 606 rolls inside the mounting groove 607, thereby reducing the friction between the guide block 601 and the guide rail 5, reducing wear during movement. Furthermore, the use of two sets of bristles 605 can clean the dust inside the guide rail 5 when the guide block 601 moves, causing the dust to accumulate on both sides inside the guide rail 5, making it easier to clean the dust inside the guide rail 5. The engaging structure of the locking block 603 and the locking groove 604 makes it easier to replace the bristles 605. After the milling cutter 12 finishes cutting the circuit board 3, the circuit board 3 can be removed, thus completing the cutting of the circuit board 3.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
