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

[0016] 1. The metal liquid is quickly cooled into metal particles by the coolant to prevent the metal liquid from depositing on the turning plate. The control system drives the laser from one end of the workpiece to be processed to the other end through the transverse electric cylinder. The laser cuts the workpiece to be processed at the same time. The metal liquid generated by the laser cutting of the workpiece to be processed falls downward into the water storage tank. The metal liquid contacts the coolant in the water storage tank, and the coolant cools the metal liquid into metal particles, preventing the metal liquid from adsorbing on the turning plate and causing the problem of difficult cleaning of the turning plate, thus solving the problem of difficult cleaning of the metal liquid.

[0017] 2. The workpiece to be processed is preheated to improve the laser cutting efficiency. The encoders in the longitudinal electric cylinders on both sides respectively feed back the displacements of the positive electrode plate and the negative electrode plate to the control system. The control system makes the negative electrode plate and the positive electrode plate contact the negative electrode and the positive electrode of the power supply respectively. There is current flowing through the workpiece to be processed between the positive electrode plate and the negative electrode plate, making the position of the workpiece to be processed that needs laser cutting heat up, reducing the strength and hardness of the position of the workpiece to be processed that needs laser cutting, so as to facilitate the laser cutting of the workpiece by the laser and improve the laser cutting efficiency.

[0018] 3. The coolant circulates to ensure that the coolant is in a state of relatively low temperature. As the protrusions on the cam alternately approach and move away from the turning plate, the turning plate continuously changes from the left-low-right-high state to the right-low-left-high state for circulation, forming the left-right turning of the turning plate. Furthermore, the coolant on the turning plate impacts from one side of the water storage tank to the other side, realizing the circulation of the coolant in the water storage tank, keeping the temperature of the coolant uniform, so as to facilitate the coolant to directly convert the metal liquid into metal particles and prevent the metal liquid from directly contacting the turning plate.

[0033] The support plate 113 is arranged on the frame 11. The two sets of longitudinal electric cylinders 12 are both vertically mirror - arranged. The upper longitudinal electric cylinder 12 is installed on the support plate 113, and the lower longitudinal electric cylinder 12 is installed on the frame 11.

The pressure sensors and the encoders are electrically connected to the control system.

[0034] Coolant is provided between the upper side of the flipping plate 31, the inner wall of the water storage tank 3, and the extension film 312. A metal plate and two semiconductors of different materials are arranged on the refrigeration plate 313. One ends of the two semiconductors of different materials are both connected to the metal plate. The two semiconductors of different materials are electrically connected to the control system through wires. The metal plate and the two semiconductors of different materials on the refrigeration plate 313 are the refrigeration ends of the Peltier effect.

[0035] Working principle: Press the start button on the control panel 1, and the device starts. The staff place the workpiece to be processed on several rollers 112. The several rollers 112 drive the workpiece to be processed to move to the right, so that the position to be cut on the workpiece is located between the positive plate 121 and the negative plate 122. The encoders in the several rollers 112 detect the position of the workpiece to be processed in real - time, realizing the intelligent positioning of the workpiece to be processed.

[0036] When the position of the workpiece to be laser - cut is located between the positive plate 121 and the negative plate 122, the control system drives the positive plate 121 and the negative plate 122 to move through the two sets of longitudinal electric cylinders 12. The upper longitudinal electric cylinder 12 drives the positive plate 121 to move downward, making the positive plate 121 contact the upper side of the workpiece to be processed. The lower longitudinal electric cylinder 12 drives the negative plate 122 to move upward, making the negative plate 122 contact the lower side of the workpiece to be processed.

[0037] When both the positive plate 121 and the negative plate 122 are in contact with the workpiece to be processed, the encoders in the longitudinal electric cylinders 12 on both sides respectively feedback the displacements of the positive plate 121 and the negative plate 122 to the control system. The control system connects the negative plate 122 and the positive plate 121 to the negative pole and the positive pole of the power supply respectively. An electric current flows through the workpiece to be processed between the positive plate 121 and the negative plate 122, making the position of the workpiece to be laser - cut heat up, reducing the strength and hardness of the position of the workpiece to be laser - cut, so as to facilitate the laser 21 to laser - cut the workpiece to be processed and improve the laser - cutting efficiency.

[0038] When the positive electrode plate 121 and the negative electrode plate 122 work for a set time, the control system cuts off the power supply of the positive electrode plate 121 and the negative electrode plate 122, and drives the positive electrode plate 121 to move upward and the negative electrode plate 122 to move downward respectively through the longitudinal cylinders 12 on both sides, so that the positive electrode plate 121 and the negative electrode plate 122 are far away from the workpiece to be processed.

[0039] When the longitudinal cylinders 12 on both sides drive the positive electrode plate 121 and the negative electrode plate 122 back to their original positions, the control system continues to drive the workpiece to move to the right through a number of rollers 112, so that the position of the workpiece to be welded moves below the laser 21, and is ready for laser cutting treatment;

[0040] When the workpiece to be processed moves below the laser 21, the control system drives the laser 21 to move from one end of the workpiece to the other end through the transverse cylinder 2. The laser 21 cuts the workpiece at the same time. The molten metal generated by the laser cutting of the workpiece to be processed falls downward into the water storage tank 3. The molten metal contacts the coolant in the water storage tank 3, and the coolant cools the molten metal into metal particles, preventing the molten metal from adsorbing on the turning plate 31 and causing problems with difficult cleaning of the turning plate 31;

[0041] During the laser cutting of the workpiece to be processed by the laser 21, the control system drives the driving gear 35 to rotate through the driving motor 351. The driving gear 35 synchronously drives the driven gear 331 to rotate through the transmission belt 36. The driving gear 35 synchronously drives the cam 341 and the stirring plate 34 to rotate. The stirring plate 34 drives the refrigerating plate 313 on the stirring piece 342 to rotate. The refrigerating plate 313 on the stirring piece 342 is electrically connected to the control system through a slip ring. The slip ring is installed on the water storage tank 3;

[0042] When the protrusion on the cam 341 approaches the turning plate 31, the protrusion on the cam 341 pushes the left end of the turning plate 31 to turn downward by a certain angle. At the same time, the left side of the turning plate 31 compresses the first spring 32. At this time, the turning plate 31 is in a state of being lower on the left and higher on the right;

[0043] When the protrusion on the cam 341 moves away from the turning plate 31, the first spring 32 is released, and the first spring 32 pushes the left end of the turning plate 31 to turn upward by a certain angle. At this time, the turning plate 31 is in a state of being lower on the right and higher on the left;

[0044] As the protrusion on the cam 341 alternately approaches and moves away from the turning plate 31, the turning plate 31 continuously changes from a state of being lower on the left and higher on the right to a state of being lower on the right and higher on the left for cycling, forming the left and right turning of the turning plate 31. Furthermore, the coolant on the turning plate 31 is impacted from one side of the water storage tank 3 to the other side, realizing the circulating flow of the coolant in the water storage tank 3, keeping the temperature of the coolant uniform, so that the coolant can directly convert the molten metal into metal particles and prevent the molten metal from directly contacting the turning plate 31.

[0045] During the left - right flipping of the flipping plate 31, the control system connects two types of semiconductors in the cooling plate 313 on one side of the extension film 312 and the cooling plate 313 on the stirring piece 342 to the circuit. The metal plate and the two types of semiconductors on the cooling plate 313 are the cooling ends of the Peltier effect. The temperature of the extension film 312 is reduced through the cooling end on one side of the extension film 312. The extension film 312 further increases the cooling area of the cooling end, causing the circulating coolant to alternately impact the extension films 312 on both sides to improve the cooling effect of the coolant, reducing the overall temperature of the coolant, so as to facilitate the conversion of the metal liquid generated during the cutting process into metal particles; the cooling plate 313 on the stirring piece 342 rotates accordingly, and the coolant is cooled again through the cooling end on the stirring piece 342 to accelerate the cooling speed of the coolant.

[0046] The metal liquid generated by laser cutting contacts the coolant on the flipping plate 31 to form metal particles. As the flipping plate 31 flips left and right, the metal particles will be deposited in the middle of the flipping plate 31. At this time, the drive motor 351 drives the driven gear 331 to rotate through the driving gear 35 and the transmission belt 36 at the same time. The driven gear 331 drives the slag discharge plate 33 to rotate, and the slag discharge plate 33 drives the metal particles and part of the coolant in the middle of the flipping plate 31 into the slag discharge cylinder 311. The coolant passes through the screen and enters the drain pipe, while the metal particles are deposited in the slag discharge pipe. The staff collects the metal particles through the slag discharge pipe to achieve the separation treatment of the coolant and the metal particles;

[0047] When the equipment works for the set time, the metal particles in the slag discharge pipe need to be discharged. At this time, the staff opens the on - off valve in the slag discharge pipe through the control system to discharge the metal particles.

[0048] During the rotation of the cam 341, when the protrusion on the outside of the cam 341 approaches the extraction plate 371, the encoder in the drive motor 351 immediately feeds the rotation data of the cam 341 back to the control system. The control system opens the solenoid valve in the water outlet 373 and closes the solenoid valve in the water inlet 372. The protrusion on the cam 341 pushes the extraction plate 371 into the extraction box 37. The extraction plate 371 compresses the return spring at the same time, so that the coolant between the extraction plate 371 and the extraction box 37 is transported to the water injection cylinder 301 through the water outlet 373 and sprayed on the flipping plate 31 through the water injection port on the water injection cylinder 301 to achieve the transportation of the coolant;

[0049] When the protrusion on the outer side of the cam 341 moves away from the extraction plate 371, the drive motor 351 feeds back the rotation data of the cam 341 to the control system. The control system opens the solenoid valve in the water inlet 372 and closes the solenoid valve in the water outlet 373. At this time, the return spring is released, and the return spring pushes the extraction plate 371 to move outward from the extraction box 37, making the chamber between the extraction box 37 and the extraction plate 371 gradually larger, thereby generating negative pressure, so that the coolant in the drain pipe enters the extraction box 37 through the water inlet 372, realizing the extraction of the coolant;

[0050] With the continuous rotation of the cam 341, more and more coolant enters the extraction box 37 through the water inlet 372 and is transported to the turning plate 31 through the water outlet 373 to realize the recycling of the coolant.

[0051] After the laser cutting of the workpiece to be processed is completed, the control system controls the laser 21 not to work and drives the laser 21 to return upward to its original position through the horizontal electric cylinder 2, so as to facilitate the next laser cutting of the workpiece to be processed. At this time, several rollers 112 continue to drive the workpiece to be processed and the processed workpiece to move to the right, and the staff collects the processed workpiece to facilitate further processing.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
