[0029] Please refer to Figures 1-4 As shown, the present utility model is a laser cutting device for circuit boards, including a processing table 1 and a cutting assembly 2. A moving assembly 3 is arranged on the top of the processing table 1, and a protective shell 5 is fixedly installed. The moving assembly 3 includes a second screw 301 and a guide block 302. The second screw 301 can drive the guide block 302 to move horizontally. A clamping assembly 4 is arranged on the top of the guide block 302. The clamping assembly 4 includes a third screw 401, a first clamping block 402 and a second clamping block 403. The third screw 401 can drive the second clamping block 403 to move vertically. One end of the protective shell 5 is rotatably connected to a rotating shaft. A fourth motor 703 is fixedly installed at one end of the protective shell 5. The output end of the fourth motor 703 is fixedly connected to the rotating shaft. A fixed plate 7 is sleeved on the rotating shaft.

The cutting assembly 2 includes a laser cutting machine 201. A chip storage box 8 is fixedly installed on the side end of the processing table 1.

[0030] When the circuit board needs to be cut, the staff first starts the third motor 701. After the output end of the third motor 701 rotates, it drives the fan blade 702 to rotate. Then, the circuit board is placed on the top of the first clamping block 402, and the two third screws 401 are rotated. After the third screws 401 rotate, they can drive the second clamping block 403 to move vertically, and can clamp and fix circuit boards of different sizes, improving practicability. Then, the second screw 301 is rotated. After the second screw 301 rotates, it can drive the guide block 302 to move horizontally. Furthermore, when the guide block 302 moves, it drives the circuit board to move through the clamping assembly 4. During the process of the circuit board moving to the processing area, it can be blown by the fan blade 702, so that the dust and adhesives on the top of the circuit board are removed, preventing the dust and adhesives from affecting the cutting speed of the circuit board and improving work efficiency. When the circuit board moves to the processing area, stop rotating the second screw 301 and start the laser cutter 201. After the laser cutter 201 is started, it can directly cut the circuit board. At this time, start the fourth motor 703. When the output end of the fourth motor 703 rotates, it drives the fixing plate 7 to rotate to a vertical state through the rotating shaft. When the fixing plate 7 rotates, it can also drive the third motor 701 and the fan blade 702 to rotate, thereby changing the blowing direction of the fan blade 702, so that the fan blade 702 can blow the chips generated during the processing of the circuit board into the chip storage box 8, and can process the waste chips while processing the circuit board, without manual cleaning, saving labor consumption. When the circuit board processing is completed, turn off the laser cutter 201, and reverse the output ends of the fourth motor 703 and the second motor 303, so that the fan blade 702, the guide block 302 and the circuit board move to the initial position. Reversing the third screw 401 can remove the circuit board and also enable the fan blade 702 to change its working state.

[0031] In one embodiment, the moving assembly 3 further includes a second motor 303. The second motor 303 is fixedly installed at the other end of the processing table 1. The output end of the second motor 303 is fixedly connected to the second screw 301, and the other end of the second screw 301 is rotatably connected to the processing table 1.

[0032] When the second screw 301 needs to be rotated, start the second motor 303, and the second motor 303 can drive the circuit board to move more stably.

[0033] In one embodiment, the guide block 302 is sleeved on the second screw 301. The guide block 302 is threadedly connected to the second screw 301 and is slidably matched with the processing table 1.

[0034] By rotating the second screw 301, the guide block 302 can move in threaded cooperation with the second screw 301 and move horizontally under the limitation of the processing table 1, so that the guide block 302 drives the circuit board to move through the clamping assembly 4.

[0035] In one embodiment, the clamping assembly 4 further includes a guide rod 404. The bottom of the third screw 401 is rotatably connected to the top of the guide block 302. The guide rod 404 is fixedly connected to the guide block 302. Both the first clamping block 402 and the second clamping block 403 are sleeved on the third screw 401 and the guide rod 404. The first clamping block 402 is rotatably connected to the third screw 401 and fixedly connected to the guide rod 404. The second clamping block 403 is in threaded cooperation with the third screw 401 and in sliding cooperation with the guide rod 404.

[0036] When the third screw 401 rotates, both the first clamping block 402 and the second clamping block 403 can be limited by the guide rod 404. At this time, the first clamping block 402 is fixed by the guide rod 404 and cannot move, and the second clamping block 403 can move vertically under the limitation of the guide rod 404.

[0037] In one embodiment, the other end of the rotating shaft is rotatably connected to the protective housing 5.

[0038] Prevent the rotating shaft from being suspended.

[0039] In one embodiment, the protective housing 5 further includes a slider 205 and a cylinder 206. The mounting end of the cylinder 206 is fixedly connected to the slider 205. The mounting end of the laser cutting machine 201 is fixedly connected to the output end of the cylinder 206.

[0040] According to the requirements of circuit board cutting, the horizontal position of the slider 205 can be adjusted, and then the laser cutting machine 201 is driven to move horizontally by the cylinder 206. Then, the cylinder 206 is started, so that the output end of the cylinder 206 pushes the laser cutting machine 201 and makes it move vertically, thereby enabling the processing of circuit boards with different cutting requirements and further improving the practicability.

[0041] In one embodiment, the protective housing 5 further includes a guide rail 202, a first motor 203 and a first screw 204.

The slider 205 is in threaded connection with the first screw 204 and in sliding cooperation with the guide rail 202.

[0042] When the output end of the first motor 203 rotates, it drives the first screw 204 to rotate. After the first screw 204 rotates, it drives the slider 205 to slide inside the guide rail 202, thereby enabling the slider 205 to drive the laser cutting machine 201 to move horizontally through the cylinder 206.

[0043] In one embodiment, a parts cabinet 9 is fixedly installed at the bottom of the processing table 1.

[0044] The interior of the parts cabinet 9 can prevent various maintenance tools, facilitating the maintenance of equipment and improving practicality.

[0045] Working principle:

[0046] When a circuit board needs to be cut, the staff first starts the third motor 701. After the output end of the third motor 701 rotates, it drives the fan blade 702 to rotate. Then, place the circuit board on the top of the first clamping block 402 and rotate the two third screws 401. After the third screws 401 rotate, they can drive the second clamping block 403 to move vertically, and can clamp and fix circuit boards of different sizes, improving practicality. Then start the second motor 303. After the output end of the second motor 303 rotates, it drives the second screw 301 to rotate. After the second screw 301 rotates, it can drive the guide block 302 to move horizontally. As a result, when the guide block 302 moves, it drives the circuit board to move through the clamping assembly 4. During the process of the circuit board moving to the processing area, it can be blown by the fan blade 702, so that the dust and adhesives on the top of the circuit board are removed, preventing the dust and adhesives from affecting the cutting speed of the circuit board and improving work efficiency. When the circuit board moves to the processing area, turn off the second motor 303 and start the laser cutting machine 201. After the laser cutting machine 201 is started, it can directly cut the circuit board. At this time, start the fourth motor 703. When the output end of the fourth motor 703 rotates, it drives the fixing plate 7 to rotate to a vertical state through the rotating shaft. When the fixing plate 7 rotates, it can also drive the third motor 701 and the fan blade 702 to rotate, thereby changing the blowing direction of the fan blade 702, so that the fan blade 702 can blow the debris generated during the processing of the circuit board into the chip storage box 8, enabling the waste chips to be processed while the circuit board is being processed, without the need for manual cleaning, saving labor consumption. When the circuit board processing is completed, turn off the laser cutting machine 201, and reverse the output ends of the fourth motor 703 and the second motor 303, so that the fan blade 702, the guide block 302 and the circuit board move to the initial position. Reversing the third screw 401 can remove the circuit board and also enable the fan blade 702 to change its working state;

[0047] At the same time, according to the requirements of circuit board cutting, the first motor 203 and the cylinder 206 can be started. When the output end of the first motor 203 rotates, it drives the first screw 204 to rotate. After the first screw 204 rotates, it drives the slider 205 to slide inside the guide rail 202. As a result, the slider 205 drives the laser cutting machine 201 to move horizontally through the cylinder 206. At the same time, when the output end of the cylinder 206 extends, it can also drive the laser cutting machine 201 to move vertically, so as to process circuit boards with different cutting requirements and further improve practicality.
