[0028] It can be understood that with reference to Figures 1 to 5, A circuit board cutting device of the present utility model includes a frame 100, a cutting mechanism 200, a conveying mechanism 300, a guiding mechanism 400 and a pressing mechanism 500. The cutting mechanism 200 includes a cutting knife 210 and a first driving member 220. The cutting knife 210 is slidably connected to the frame 100, and the first driving member 220 is used to drive the cutting knife 210 to move up and down to cut the circuit board. The conveying mechanism 300 includes a second driving member 310 and multiple conveying rollers 320. The multiple conveying rollers 320 are horizontally arranged in parallel. The conveying rollers 320 are rotatably connected to the frame 100, and the second driving member 310 is used to drive the conveying rollers 320 to rotate to convey the circuit board to the cutting knife 210. The guiding mechanism 400 includes multiple groups of guiding wheels 410. Each group of guiding wheels 410 includes two guiding wheels 410. The two guiding wheels 410 are symmetrically arranged on the frame 100, and the circuit board can pass between the two guiding wheels 410. The pressing mechanism 500 includes multiple groups of pressing wheels 510. Each group of pressing wheels 510 includes two pressing wheels 510. The two pressing wheels 510 are symmetrically arranged on the frame 100, and the pressing wheels 510 can abut against the upper surface of the circuit board.

[0029] During use, place the circuit board on the conveying rollers 320, and drive the conveying rollers 320 to rotate through the second driving member 310 to convey the circuit board to the cutting knife 210. When the circuit board moves a preset distance towards the cutting knife 210, drive the cutting knife 210 to move up and down through the first driving member 220 to cut the circuit board on the conveying rollers 320. Since each group of guiding wheels 410 includes two guiding wheels 410, and the two guiding wheels 410 are symmetrically arranged on the frame 100, when the circuit board passes between the two guiding wheels 410, the two guiding wheels 410 abut against and limit the circuit board from both sides to guide the circuit board to be conveyed towards the cutting knife 210, which can reduce the possibility of the circuit board deviating horizontally. At the same time, by abutting the pressing wheels 510 against the upper surface of the circuit board to press the circuit board, the possibility of the circuit board warping can be reduced, thereby improving the cutting quality and efficiency.

[0030] It should be noted that the guiding wheels 410 can be axially vertically arranged, and the two symmetrically arranged guiding wheels 410 respectively abut against the opposite side walls of the circuit board to limit the horizontal shaking of the circuit board. And since the guiding wheels 410 rotate synchronously when the circuit board moves, the wear of the circuit board can be reduced to improve the forming quality of the circuit board.

[0031] The pressing wheels 510 are axially parallel to the conveying rollers 320, and the pressing wheels 510 are located above the conveying rollers 320, so that the pressing wheels 510 can cooperate with the conveying rollers 320 to clamp and convey the circuit board to improve the stability of the circuit board conveying. And since the circuit board can drive the pressing wheels 510 to rotate when moving, the wear of the circuit board can be reduced to improve the forming quality of the circuit board.

[0032] The first driving member 220 can be a cylinder, an oil cylinder, an electric telescopic rod, etc., which can drive the cutting knife 210 to move up and down to cut the circuit board. The second driving member 310 can be a servo motor or a stepping motor, etc., which can drive the conveying roller 320 to rotate.

[0033] It can be understood that, referring to Figures 1 to 3 , along the conveying direction of the conveying mechanism 300, at least one set of guide wheels 410 is arranged on each of the opposite sides of the cutting knife 210. Since at least one set of guide wheels 410 is arranged on each of the opposite sides of the cutting knife 210 along the conveying direction of the conveying mechanism 300, the two ends of the circuit board are respectively guided and limited by the guide wheels 410 on the opposite sides of the cutting knife 210, which can further reduce the possibility of the circuit board shifting horizontally, so as to improve the position stability during the cutting of the circuit board, thereby improving the cutting quality.

[0034] It can be understood that, referring to Figures 1 to 3 , multiple sets of guide wheels 410 are arranged at equal intervals along the conveying direction of the conveying mechanism 300. Since multiple sets of guide wheels 410 are arranged at equal intervals along the conveying direction of the conveying mechanism 300, both when the conveying mechanism 300 feeds and discharges materials to the cutting mechanism 200, it can be guided and limited by the guide wheels 410, so as to reduce the possibility of the circuit board shifting horizontally during the conveying process, thereby improving the stability of the circuit board conveying.

[0035] It can be understood that, referring to Figures 1 to 3 , along the conveying direction of the conveying mechanism 300, at least one set of pressing wheels 510 is arranged on each of the opposite sides of the cutting knife 210. Since at least one set of pressing wheels 510 is arranged on each of the opposite sides of the cutting knife 210 along the conveying direction of the conveying mechanism 300, the two ends of the circuit board are respectively pressed by the pressing wheels 510 on the opposite sides of the cutting knife 210, which can further reduce the possibility of the circuit board warping, so as to improve the position stability during the cutting of the circuit board, thereby improving the cutting quality.

[0036] It can be understood that, referring to Figures 1 to 3 , multiple sets of pressing wheels 510 are arranged at equal intervals along the conveying direction of the conveying mechanism 300. Since multiple sets of pressing wheels 510 are arranged at equal intervals along the conveying direction of the conveying mechanism 300, both when the conveying mechanism 300 feeds and discharges materials to the cutting mechanism 200, it can be pressed by the pressing wheels 510, so as to reduce the possibility of the circuit board warping during the conveying process, thereby improving the stability of the circuit board conveying.

[0037] It can be understood that, referring to Figures 1 to 4, the guiding mechanism 400 further includes a plurality of adjusting components 420. The adjusting components 420 correspond to the guiding wheels 410 one by one. The adjusting component 420 includes a fixed seat 421, a support rod 422 and a connecting block 423. The fixed seat 421 is fixedly arranged on the frame 100. The support rod 422 is slidably connected to the fixed seat 421. The support rod 422 can move along the axial direction of the conveying roller 320. The connecting block 423 is arranged at one end of the support rod 422. The guiding wheel 410 is rotatably connected to the connecting block 423. Since the support rod 422 is slidably connected to the fixed seat 421, the connecting block 423 is arranged at one end of the support rod 422, and the guiding wheel 410 is rotatably connected to the connecting block 423, by moving the support rod 422 along the axial direction of the conveying roller 320, the support rod 422 drives the guiding wheel 410 to move along the axial direction of the conveying roller 320, and the distance between two corresponding guiding wheels 410 can be adjusted to adapt to the guiding and limiting of circuit boards with different widths, thereby improving the applicability of the circuit board cutting device.

[0038] It should be noted that when the support rod 422 moves to a preset position along the axial direction of the conveying roller 320, positioning can be carried out through fasteners such as bolts or pins.

[0039] It can be understood that referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the pressing mechanism 500 further includes a plurality of rotating components 520. The rotating components 520 correspond to the pressing wheels 510 one by one. The rotating component 520 includes a support block 521, a rotating rod 522 and a mounting block 523. The support block 521 is fixedly arranged on the frame 100. The rotating rod 522 is rotatably connected to the support block 521. The rotating rod 522 is arranged parallel to the axial direction of the conveying roller 320. The rotating rod 522 can rotate around the axial direction. The mounting block 523 is arranged at one end of the rotating rod 522. The pressing wheel 510 is rotatably connected to the mounting block 523. Since the rotating rod 522 is rotatably connected to the support block 521, the rotating rod 522 is arranged parallel to the axial direction of the conveying roller 320, the mounting block 523 is arranged at one end of the rotating rod 522, and the pressing wheel 510 is rotatably connected to the mounting block 523, by rotating the rotating rod 522 to drive the mounting block 523 and the pressing wheel 510 to rotate around the axial direction of the rotating rod 522, the vertical height of the pressing wheel 510 can be adjusted, so as to adjust the distance between the pressing wheel 510 and the conveying roller 320 to adapt to the pressing of different circuit boards, thereby improving the applicability of the circuit board cutting device.

[0040] It should be noted that the axis of the pressing wheel 510 is located at an eccentric position on the central axis of the rotating rod 522. When the rotating rod 522 rotates around the axial direction, the pressing wheel 510 rotates eccentrically around the central axis of the rotating rod 522, so that the vertical height of the pressing wheel 510 can be adjusted.

[0041] When the rotating rod 522 rotates to a preset angle, positioning can be carried out through fasteners such as bolts or pins.

[0042] It is understandable that, with reference to Figure 1 , the cutting mechanism 200 further includes a mounting plate 230. The first driving member 220 is fixedly arranged on the frame 100. The mounting plate 230 is connected to the output end of the first driving member 220. The cutting knife 210 is mounted on the side of the mounting plate 230 facing away from the first driving member 220. Since the mounting plate 230 is connected to the output end of the first driving member 220 and the cutting knife 210 is mounted on the side of the mounting plate 230 facing away from the first driving member 220, the first driving member 220 drives the mounting plate 230 to move up and down, so as to drive the cutting knife 210 to move up and down, thereby enabling the cutting of the circuit board.

[0043] Specifically, with reference to Figure 1 , a vertical guide rod 231 is arranged on the side of the mounting plate 230 facing away from the cutting knife 210. The frame 100 is provided with a vertical guide sleeve 110. The guide rod 231 is movably inserted through the guide sleeve 110. Since the guide rod 231 is movably inserted through the guide sleeve 110, the guide rod 231 moves vertically up and down along the guide sleeve 110 to guide the mounting plate 230 and the cutting knife 210 to move vertically up and down, which can improve the stability of the vertical movement of the cutting knife 210, thereby improving the stability of the circuit board cutting.

[0044] It is understandable that, with reference to Figure 2 and Figure 3 , a collection box 600 is arranged at the output end of the conveying mechanism 300. A baffle 610 is arranged on the side of the collection box 600 away from the cutting knife 210. When the circuit board after cutting is output to the side close to the collection box 600, the baffle 610 blocks the position where the circuit board flies away from the collection box 600, so that the circuit board falls into the collection box 600 for collection and storage, which can facilitate the centralized transfer of the cut circuit board.

[0045] It should be noted that a buffer block 620 can be arranged on the side of the baffle 610 close to the cutting knife 210. The buffer block 620 can be an elastic part such as rubber or silica gel. The buffer block 620 enables the circuit board to be buffered when colliding with the baffle 610, thereby being able to reduce the collision wear of the circuit board.
