[0002] The dual-stage linkage laser cutting device is a laser cutting equipment that achieves efficient continuous production through the alternating operation of two worktables. Its core design lies in the linkage control of two independent worktables, combined with laser cutting technology to achieve high-precision processing of materials. Existing laser cutting devices are inconvenient to accurately determine the position of the circuit board during laser cutting of circuit boards, and the cutting efficiency of circuit boards is low, requiring a long time. At the same time, the harmful gases generated during the laser cutting of circuit boards contain dust, which can easily clog the filter device and affect the efficiency of absorbing harmful gases. Summary of the Invention

[0004] (1) How to solve the problem that it is inconvenient to accurately determine the position of the circuit board and that the efficiency of cutting the circuit board is low and the time required is long.

[0005] (2) How to solve the problem that the generated harmful gases contain dust, which can easily clog the filter device and affect the efficiency of absorbing harmful gases.

[0006] The objective of this invention can be achieved through the following technical solution: a dual-stage linkage laser cutting device, including a worktable and an installation frame disposed on one side thereof, a shell is fixedly disposed on the top of the worktable, a marble base is fixedly disposed on the top of the worktable inside the shell, and a cleaning mechanism for filtering harmful gases is disposed on the top of the installation frame.

[0007] An X-axis is fixedly mounted on one end of the marble base, a Z-axis is slidably mounted on the X-axis, a camera is slidably mounted on the Z-axis, and a galvanometer + focusing lens module is fixedly mounted on the Z-axis to one side of the camera; a laser is fixedly mounted on the top of the marble base near the X-axis, an optical path is provided on the marble base to one side of the laser, the input end of the optical path is fixedly connected to the output end of the laser, and the output end of the optical path is connected to the galvanometer + focusing lens module through an optical fiber.

[0008] A further technical improvement of the present invention is that: a first Y-axis and a second Y-axis are fixedly provided at the other end of the marble base, a right platform is slidably provided on the first Y-axis, and a left platform is slidably provided on the second Y-axis.

[0009] A further technical improvement of the present invention is as follows: a fume hood for absorbing harmful gases is fixedly installed at the bottom of the Z-axis, and the bottom of the fume hood is higher than the top of the right platform and the left platform; by manually operating the controller, the left platform is first controlled to slide on the first Y-axis to the processing station, and then the Z-axis is controlled to slide on the X-axis to be directly above the left platform. A camera is used to achieve mark positioning, and the Z-axis is operated to easily find the position of the laser focus and save the focus position in the cutting document. The Z-axis can automatically position the focus position. The galvanometer + focusing lens module is used to use laser to cut the circuit board to be processed on the left platform. At the same time, the focusing lens enables the laser to be focused, and the galvanometer tilting enables the laser to complete multiple path cutting. After completing the laser cutting of the circuit board to be processed on the left platform, the above-mentioned corresponding operations are performed on the right platform. With the X-axis movement, the laser can hit both the left platform and the right platform, which is convenient for laser cutting the circuit board to be processed on the right platform. At the same time, the left platform is operated to slide on the first Y-axis to the unloading station. The above process realizes fast and accurate laser cutting of the circuit board to be processed.

[0010] A further technical improvement of the present invention is that: the cleaning mechanism includes a box fixedly connected to the mounting frame, a filter box is fixedly installed on the inner side wall of the box near the outer shell, an air suction pipe is connected to the lower middle part of the filter box, and the input end of the air suction pipe is connected to the output end of the fume hood through an air extraction hose.

[0011] A further technical improvement of the present invention is that: a filter screen is fixedly installed in the middle of the inner wall of the filter box, and a horizontally arranged electric push rod is fixedly installed in the middle of the outer wall of the filter box. The extended end of the electric push rod movably penetrates through the filter box and is fixedly installed with a brush for cleaning the filter screen, the brush being located above the filter screen.

[0012] A further technical improvement of the present invention is that: an air pump is fixedly installed on the inner wall of the filter box on one side, an adsorption box is installed above the air pump, and a HEPA filter layer and an activated carbon adsorption layer are arranged sequentially from top to bottom inside the adsorption box. The top of the filter box is connected to the top of the adsorption box through a first filter tube.

[0013] A further technical improvement of the present invention is that a catalytic oxidation device for decomposing ozone and VOCs is fixedly installed at the bottom of the inner wall of the box. The catalytic oxidation device is existing technology, and the output end of the catalytic oxidation device is connected to an exhaust pipe.

[0014] A further technical improvement of the present invention is as follows: the input end of the air pump is connected to the bottom of the adsorption box through the second filter tube, and the output end of the air pump is connected to the input end of the catalytic oxidation tooling; by turning on the air pump in advance, a high negative pressure is generated below the fume hood, and the harmful gas generated by cutting is drawn away through the fume hood and sucked into the filter box along the air extraction hose and suction pipe. The dust in the harmful gas is filtered out by the filter screen, and then the harmful gas is injected into the adsorption box along the first filter tube. The heavy metal particles and metal oxide particles of PM0.3 are adsorbed by the HEPA filter layer, and organic toxins such as benzene and formaldehyde are adsorbed by the activated carbon adsorption layer. Then, it is injected into the catalytic oxidation tooling through the second filter tube and the air pump. Using plasma technology, ozone and VOCs are decomposed to prevent the exhaust gas from harming the surrounding environment; when the working time reaches the threshold, the extension end of the electric push rod is controlled to extend to its maximum length and then immediately retract to its minimum length, so that the brush brushes off the dust accumulated on the filter screen to prevent it from clogging and avoid affecting the efficiency of the fume hood in removing harmful gases.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In use, this invention involves manually operating a controller to first slide the left platform along the first Y-axis to the processing station, then controlling the Z-axis to slide along the X-axis to directly above the left platform. A camera is used for mark positioning, and the Z-axis is operated to easily find the laser focus position, which is saved in the cutting document. This allows for automatic Z-axis focus positioning. The galvanometer and focusing lens module is used to laser cut the circuit board to be processed on the left platform. Simultaneously, the focusing lens enables the laser to be focused, and the galvanometer's tilt allows the laser to complete various path cutting. After laser cutting the circuit board to be processed on the left platform, the same operation is performed on the right platform. With the X-axis movement, the laser can hit either the left or right platform, facilitating laser cutting of the circuit board to be processed on the right platform. At the same time, the left platform is operated to slide along the first Y-axis to the unloading station. The above process achieves fast and accurate laser cutting of the circuit board to be processed.

[0017] In use, this invention utilizes a pre-activated air pump to create a high negative pressure below the fume hood, drawing away harmful gases generated during cutting. These gases are then drawn into a filter box via the extraction hose and suction pipe. A filter screen removes dust from the harmful gases, which are then injected into an adsorption box through a first filter tube. A HEPA filter layer adsorbs PM0.3 particles, heavy metal particles, and metal oxide particles, while an activated carbon layer adsorbs organic toxins such as benzene and formaldehyde. Finally, the gases are injected into a catalytic oxidation fixture via a second filter tube and air pump. Plasma technology is used to decompose ozone and VOCs, preventing the emitted gases from harming the surrounding environment. When the operating time reaches a threshold, the extension of the electric push rod is controlled to extend to its maximum length and then immediately retract to its minimum length. This allows the brush to remove accumulated dust from the filter screen, preventing blockage and ensuring the fume hood's efficiency in removing harmful gases. Attached Figure Description

Using the manual operation controller 2, the left platform 17 is first controlled to slide along the first Y-axis 16 to the processing station, and then the Z-axis 11 is controlled to slide along the X-axis 12 to directly above the left platform 17.

[0039] Working Principle: In use, the two circuit boards to be processed are first placed on the right platform 15 and the left platform 17 respectively. Using the manual control controller 2, the left platform 17 is first slid along the first Y-axis 16 to the processing station, and then the Z-axis 11 is slid along the X-axis 12 to directly above the left platform 17. The camera 19 is used for mark positioning. Operating the Z-axis 11 allows for easy location of the laser focus position, and the focus position is saved in the cutting document. This enables automatic focus positioning via the Z-axis 11, achieved through a galvanometer and focusing lens. The head module 21 uses a laser to cut the circuit board to be processed on the left platform 17. Simultaneously, a focusing lens enables the laser to be focused, and the tilting of the galvanometer allows the laser to perform various path cuts. After completing the laser cutting of the circuit board on the left platform 17, the same operation is performed on the right platform 15. Coordination with the X-axis 12 movement allows the laser to strike either the left or right platform 15, facilitating laser cutting of the circuit board on the right platform 15. Simultaneously, the left platform 17 slides down along the first Y-axis 16. At the material handling station, the above process enables rapid and precise laser cutting of the circuit board to be processed. By pre-activating the air pump 608, a high negative pressure is generated below the fume hood 20, which draws away the harmful gases generated during cutting. These gases are then drawn into the filter box 605 along the exhaust hose 9 and the suction pipe 604. The dust in the harmful gases is filtered out by the filter screen 603, and then injected into the adsorption box 611 along the first filter pipe 602. The HEPA filter layer then adsorbs PM0.3 heavy metal particles and metal oxide particles. The activated carbon adsorption layer adsorbs organic toxins such as benzene and formaldehyde, which are then injected into the catalytic oxidation fixture 606 through the second filter tube 609 and the air pump 608. Using plasma technology, ozone and VOCs are decomposed to prevent the emitted gases from harming the surrounding environment. When the working time reaches the threshold, the electric push rod 610 is controlled to extend to its maximum length and then immediately retract to its minimum length, so that the brush 612 brushes off the dust accumulated on the filter screen 603 to prevent it from clogging and avoid affecting the efficiency of the fume hood 20 in removing harmful gases.
