[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] Please see Figures 1-3 The present invention provides the following technical solution:

[0029] Example 1, see Figure 1A cutting tool diameter adjustment mechanism for a circuit board cutting device includes a bracket 1, a moving component 2 disposed on one side of the bracket 1, and an adjustment component 3 installed on the side wall of the moving component 2. A cutting component 4 is installed inside the adjustment component 3. The moving component 2 is used to drive the adjustment component 3 to move, thereby adjusting the position of the cutting component 4. The adjustment component 3 is used to adjust the height of the cutting component 4 so that the cutting component 4 can meet the cutting of circuit boards of different thicknesses.

[0030] See Figure 1 and Figure 2 The moving component 2 includes a slide block 22 slidably connected to one side of the bracket 1. The adjusting component 3 is installed on the side wall of the slide block 22. A guide rail 24 is installed on the side wall of the bracket 1. A slider 23 is installed on the side of the slide block 22 near the bracket 1. The slider 23 is slidably connected to the side wall of the guide rail 24. The slider 23 and the guide rail 24 cooperate to connect the slide block 22 and the bracket 1. The slide block 22 slides on the side wall of the bracket 1 by the interaction of the slider 23 and the guide rail 24.

[0031] See Figure 1 and Figure 2 The moving component 2 also includes a drive motor 25 mounted on the top of the slide 22. The output end of the drive motor 25 is connected to a gear 27. A rack 21 is mounted on the top of the bracket 1. The drive motor 25 is used to drive the gear 27 to rotate. Since the gear 27 meshes with the rack 21, the gear 27 can roll on the top of the rack 21 when it rotates, thereby providing driving force for the sliding of the slide 22. A mounting base 26 is mounted on the top of the slide 22. The mounting base 26 is used to protect the drive motor 25.

[0032] See Figure 1 and Figure 2 The adjusting assembly 3 includes a fixed plate 31 horizontally mounted on the inner wall of the slide block 22 and a cylinder 32 vertically mounted on the top of the fixed plate 31. The piston rod of the cylinder 32 vertically penetrates the fixed plate 31 and is connected to a pressure plate 34. A frame 35 is mounted on the bottom of the pressure plate 34, and two guide rods 33 are vertically connected to the top of the pressure plate 34. Both guide rods 33 penetrate the fixed plate 31. The cylinder 32 is used to drive the pressure plate 34 and the frame 35 to move up and down. During the up and down movement, the pressure plate 34 drives the two guide rods 33 to move up and down. The top of the fixed plate 31 has a through hole that matches the guide rods 33. The guide rods 33 slide inside the through hole while moving up and down, thereby limiting and guiding the pressure plate 34.

[0033] See Figure 1 and Figure 2 The cutting component 4 is installed inside the frame 35. When the frame 35 moves up and down to adjust its height, the cutting component 4 can adjust synchronously, so that the cutting component 4 can meet the cutting of circuit boards of different thicknesses.

[0034] See Figure 2 and Figure 3 The cutting assembly 4 includes a cutting seat 41 installed inside the frame 35. A cutting motor 42 is installed on the top of the cutting seat 41. A rotating shaft 43 is horizontally connected to the output end of the cutting motor 42. Multiple cutters 44 are equidistantly connected to the outer side wall of the rotating shaft 43. A cover 45 is installed on the top of the cutting seat 41. The cover 45 covers the top of the multiple cutters 44 and is used to protect the cutters 44. The cutting motor 42 is used to drive the rotating shaft 43 to rotate, which causes the rotating shaft 43 to drive the multiple cutters 44 to rotate. While the cutters 44 are rotating, the horizontal displacement is controlled by the moving assembly 2, thereby cutting and separating the circuit board.

[0035] See Figures 1-3 The bottom of the bracket 1 is connected to a connecting plate 37. The side wall of the connecting plate 37 is provided with a slot 38. The frame 35 is connected to a limiting rod 36 on the side near the bracket 1. The end of the limiting rod 36 is inserted into the inside of the slot 38. When the circuit board is cut, the cutting component 4 and the moving component 2 cooperate to complete a back-and-forth two-way cutting, so that the circuit board is cut into separate boards. At the same time, when the cutting component 4 cuts the circuit board for the first time, the cylinder 32 remains in a contracted state, causing the limiting rod 36 to slide horizontally at the top of the slot 38. At this time, the cutting component 4 is in a higher position. After completing one cutting, the cylinder 32 pushes the pressure plate 34 and the frame 35 to move down. At this time, the limiting rod 36 moves to the bottom of the slot 38, and the height of the cutting component 4 decreases. When the cutting component 4 cuts for the second time, its cutting diameter increases, thus cutting the circuit board smoothly and avoiding damage to the circuit board when the cutting component 4 cuts at a low position.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
