[0034] Embodiment

[0035] As Figure 1 shown, a PCB board splitting machine proposed by the present utility model includes a platform 1 and a machine cover 2 installed on the top of the platform 1.

[0036] Further, please refer to Figure 1-3, the above-mentioned board cutting machine includes a moving mechanism 3. A board 5 is placed on the moving mechanism 3 and the moving mechanism 3 drives the board 5 to move. A breaking point 51 is provided on the surface of the board 5 to facilitate cutting. The moving mechanism 3 includes a linear motor 31, a moving plate 32, a moving table 33, a slide rail 34, and a slider 35. The linear motor 31 is installed at the bottom of the platform 1. The moving end of the linear motor 31 is fixedly connected to the moving plate 32. The top of the moving plate 32 penetrates through the platform 1 and is fixedly connected to the moving table 33. The linear motor 31 drives the moving table 33 to move through the moving plate 32. At least two groups of slide rails 34 are installed on the top of the platform 1. At least one group of sliders 35 is slidably connected to the top of the slide rail 34. The slider 35 is fixedly connected to the bottom of the moving table 33. The moving table 33 moves smoothly under the limiting action of the slide rail 34 and the slider 35. An installation groove 36 is provided on the top of the moving table 33 for placing the placing mold 4. The outer sizes of different models of the placing mold 4 are the same, so that the position is stable after being placed in the installation groove 36.

[0037] Furthermore, as Figure 2 shown, the above-mentioned board cutting machine further includes a replaceable placing mold 4, and the placing mold 4 is installed on the moving mechanism 3. A placing groove 41 is provided on the placing mold 4. The board 5 is placed in the placing groove 41. According to different models of the board 5, placing grooves 41 with different sizes are provided on different placing molds 4. A plurality of knife grooves 42 are provided on the placing mold 4. The positions of the knife grooves 42 correspond to the breaking points 51, which is convenient for the blade 65 to completely penetrate the board 5 and cut the board 5 into small pieces.

[0038] Specifically, please refer to Figure 3-5, the above-mentioned circuit board cutting machine includes two sets of vertically arranged circuit board cutting mechanisms 6. The circuit board cutting mechanisms 6 are installed in the machine cover 2. The circuit board cutting mechanism 6 includes multiple groups of equally spaced blades 65, which move downward to cut the board 5. The circuit board cutting mechanism 6 further includes a push rod motor 61, a fixed frame 62, a moving frame 63, and a mounting block 64. The push rod motor 61 is installed on the top wall of the machine cover 2. The output end of the push rod motor 61 faces downward and is fixedly connected to the fixed frame 62. The fixed frame 62 is arranged in a "U" shape. The bottom of the fixed frame 62 is fixedly connected to the moving frame 63. After the push rod motor 61 is started, it can drive the moving frame 63 to move downward. Multiple mounting blocks 64 are slidably connected in the moving frame 63. The multiple mounting blocks 64 are equally spaced. The mounting blocks 64 can slide to change their positions so as to adapt to different models of boards 5. Multiple blades 65 are respectively fixedly connected to the bottoms of the multiple mounting blocks 64, so that the blades 65 move downward synchronously with the moving frame 63 close to the board 5 and press on the board 5 to cut the board 5. The circuit board cutting mechanism 6 further includes a fixed cylinder 66, a limit rod 67, and a limit disc 68. Two fixed cylinders 66 are symmetrically arranged on both sides of the push rod motor 61. The top of the fixed cylinder 66 is fixedly connected to the machine cover 2. A limit rod 67 is slidably connected in the fixed cylinder 66. The bottom of the limit rod 67 is fixedly connected to the fixed frame 62, so that the fixed frame 62 moves smoothly. A limit disc 68 is further installed at the top of the limit rod 67 to prevent the fixed frame 62 from moving downward too much distance, thereby preventing the blades 65 from moving downward too much distance and causing damage to the cutting edge.

[0039] Finally, the above-mentioned circuit board cutting machine further includes an adjusting component 7 for adjusting the spacing between the blades 65. The adjusting component 7 includes a first connecting plate 71, a second connecting plate 72, a limiting column 73, and a limiting frame 74. Above the moving frame 63, multiple groups of first connecting plates 71 are provided. The number of the first connecting plates 71 corresponds to that of the mounting blocks 64. Above each group of first connecting plates 71, a group of second connecting plates 72 are provided. The first connecting plates 71 and the second connecting plates 72 are cross - arranged and rotatably connected to the top of the mounting blocks 64. The two ends of the first connecting plates 71 and the second connecting plates 72 are rotatably connected with the limiting columns 73. Two groups of limiting frames 74 are also installed on the top of the moving frame 63. The limiting columns 73 are slidably connected in the limiting frames 74. The two limiting columns 73 far from the mounting frame 75 are fixedly arranged on the top of the moving frame 63, so that multiple groups of first connecting plates 71 and second connecting plates 72 deflect synchronously, thereby synchronously adjusting the positions of multiple groups of blades 65, and the spacing between the blades 65 remains equal. The adjusting component 7 further includes a mounting frame 75, a servo motor 76, and a threaded rod 77. The mounting frame 75 is slidably connected to one side of the moving frame 63. The mounting frame 75 is arranged in a "U" shape and moves smoothly. A servo motor 76 is installed on the side of the mounting frame 75 far from the moving frame 63. The output of the servo motor 76 penetrates through the mounting frame 75 and is fixedly connected with a threaded rod 77. After the servo motor 76 is started, it drives the threaded rod 77 to rotate. The threaded rod 77 penetrates through the moving frame 63 and is threadedly connected thereto. The threaded rod 77 is perpendicular to the mounting block 64. One end of the threaded rod 77 is rotatably connected to a group of mounting blocks 64 close to the servo motor 76, so that when the threaded rod 77 rotates, it moves along its own length direction, and at the same time drives the mounting block 64 to move to adjust the spacing between multiple groups of blades 65.

[0040] In this embodiment, first, select the placement mold 4 corresponding to the plate 5 to be separated, place the plate 5 in the placement groove 41, and then place the placement mold 4 in the moving table 33. At this time, the break point 51 corresponds to the cutter groove 42. Start the servo motor 76, and the servo motor 76 drives the threaded rod 77 to rotate. When the threaded rod 77 rotates, it is threadedly connected to the moving frame 63. The threaded rod 77 moves along its own length direction, and at the same time drives a group of mounting blocks 64 rotationally connected to it to move. At the same time, the mounting frame 75 slides in the moving frame 63. At this time, through the arrangement of multiple groups of the first connecting plates 71 and the second connecting plates 72, when the mounting blocks 64 move, they drive multiple groups of mounting blocks 64 to move synchronously through the first connecting plates 71 and the second connecting plates 72, and their spacing is equal. At this time, adjust the position of the cutting blade 65 so that it corresponds to the break point 51. Then start the linear motor 31, and the linear motor 31 drives the moving table 33 to move through the moving plate 32. The moving table 33 moves smoothly under the limiting action of the slide rail 34 and the slider 35 and enters the machine cover 2. After the plate 5 moves under the splitting mechanism 6, the push rod motor 61 starts to drive the fixed frame 62 to move downward. At the same time, the fixed frame 62 moves smoothly downward under the limiting action of the fixed cylinder 66 and the limiting rod 67, driving the moving frame 63 to move downward. At the same time, multiple groups of cutting blades 65 approach the plate 5 and cut the plate 5 along the break point 51. At the same time, through the vertical cutting blades 65 in the two vertically arranged splitting mechanisms 6, the plate 5 is cut into small pieces.

[0041] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
