[0024] The upper part of the limit frame 9 is provided with a chamfer to facilitate the picking and placing of the filter.

[0025] It also includes a wire frame 101 and a filter screen 102; the wire frame 101 is detachably connected inside the support plate 8; several partition bars are provided inside the wire frame 101, and the partition bars divide the wire frame 101 into several air filtering areas, and several through holes are opened on the partition bars for communicating adjacent air filtering areas; several filter screens 102 are fixedly connected inside the wire frame 101, and each filter screen 102 is located in an air filtering area inside the wire frame 101, and the through holes on the partition bars are located below the filter screens 102.

[0026] The filter screen 102 is in a concave state with the middle lower and both sides higher in the left-right direction to increase the contact area between the filter screen 102 and the air.

[0027] The working steps of the above embodiment are as follows: Before using this cutting device, transfer the supporting plate 8 and the original filter plate to the vicinity of this cutting device through an external conveyor belt respectively. Then, control the external manipulator to suck the supporting plate 8 from one external conveyor belt and place it on a flat table. The external manipulator releases the fixation of the supporting plate 8. Then, the external manipulator sucks the original filter plate from the other external conveyor belt and transfers it to the right part of the electric conveyor belt 4. The limit frame 9 limits the original filter plate. Then, the external manipulator transfers the supporting plate 8 to the electric conveyor belt 4. Then, control to start the electric conveyor belt 4. The rollers of the electric conveyor belt 4 drive the belt thereon to rotate, synchronously driving the supporting plate 8 to move leftward. The supporting plate 8 passes under the observation cover 2 and then moves under the laser cutting head 6. The infrared distance sensor arranged at the lower part of the skeleton of the three-axis manipulator 5 installed on the machine table 1 monitors the width of the supporting plate 8 entering the observation cover 2. When the supporting plate 8 completely enters, according to the width data of the supporting plate 8 obtained by the infrared distance sensor, control the electric sliders 11 on each electric guide rail 10 to move in the direction away from each other. When the distance between two adjacent electric sliders 11 on the left and right is the width of the supporting plate 8, all the electric sliders 11 synchronously transfer under the supporting plate 8, so that the hollow plate 14 drives the electromagnet 15 to reach directly below the magnetic block 7. The electromagnets 15 correspond to the magnetic blocks 7 one by one. The hollow plate 14 continues to move and remains relatively stationary with the supporting plate 8. Then, control all the electric actuators 12 to contract, synchronously driving the L-shaped plate 13 and the corresponding parts thereon to move upward. Each air nozzle 1401 is inserted into the central hole of a magnetic block 7. Then, control to start all the electromagnets 15. Each electromagnet 15 attracts a magnetic block 7, realizing that the supporting plate 8 is fixed by all the electromagnets 15. Then, control the electric actuator 12 to continue to contract, synchronously driving the supporting plate 8 to move upward, so that the supporting plate 8 is separated from the belt of the electric conveyor belt 4. At the same time, an external vacuum pump is connected to the hollow plate 14 through a trachea. The external air pump pumps out the air in the hollow plate 14. The hollow plate 14 then pumps out the air in the cavity of the supporting plate 8 through the air nozzle 1401. The cavity of the supporting plate 8 is in negative pressure, realizing that the original filter plate is tightly adsorbed and fixed. Then, the three-axis manipulator 5 can be used to control the laser cutting head 6 to approach the original filter plate according to the set cutting program. Then, control to start the laser cutting head 6, and then use the laser cutting head 6 to cut the original filter plate. After completing the cutting of the original filter plate, control to turn off all the electromagnets 15. The electromagnets 15 no longer attract the magnetic blocks 7. Control the external air pump to stop pumping air. At the same time, control all the electric actuators 12 to extend, synchronously driving the L-shaped plate 13 and the corresponding parts thereon to move downward, thereby realizing the lowering of the supporting plate 8. The electric conveyor belt 4 continues to move at a constant speed until the supporting plate 8 is completely placed on the belt of the electric conveyor belt 4. Finally, the air nozzle 1401 quickly withdraws from the central hole of the corresponding magnetic block 7. At this time, the supporting plate 8 can continue to move leftward until the supporting plate 8 leaves under the observation cover 2.Then, the external manipulator can transfer the support plate 8 and the filter on it to the next process for processing.

[0028] In the above work, by setting the belt of the electric conveyor belt 4 into several strips with gaps between the belts, several magnets 7 can be arranged on the support plate 8 at the gaps. Then, by attracting the magnets 7 with the electromagnet 15, the stable support of the support plate 8 can be realized. When the electric actuator 12 contracts, the hollow plate 14 moves upward, and then the support plate 8 is separated from the electric conveyor belt 4. The electromagnet 15 also supports the support plate 8, so that during the cutting process of the support plate 8, it will not be affected by the vibration of the electric conveyor belt 4, resulting in a decrease in cutting accuracy. And the electromagnet 15 will not contact the belt of the electric conveyor belt 4. Then, by evacuating the cavity of the support plate 8, the cavity of the support plate 8 is in negative pressure, and then the filter is evenly adsorbed on the support plate 8, which can effectively fix filters with different thicknesses, reduce stress concentration during the fixing process, resulting in material deformation or breakage, and also ensure that the filter is stable and immovable during the cutting process of the filter, effectively improving the cutting accuracy and consistency significantly.

[0029] At the same time, considering that during the cutting process of the original filter plate on the support plate 8, debris will also be generated. After the filter is cut through, some of the suction holes 8001 on the upper part of the support plate 8 will be exposed. The debris will enter the support plate 8 along with the outside air due to the negative pressure inside the support plate 8. Therefore, a grid 101 and a filter screen 102 are arranged in the cavity of the support plate 8. The air entering from the suction holes 8001 on the upper part of the support plate 8 will pass through the filter screen 102, and the filter screen 102 will intercept the debris. The arc-shaped filter screen 102 effectively increases the contact area with the air and reduces the situation where the filter screen 102 is blocked, resulting in a decrease in the adsorption and fixing effect of the support plate 8 on the filter. At the same time, combined with this support plate 8 that can be separated from the electric conveyor belt 4, by controlling the distance between the electric sliders 11 between the same electric guide rails 10, it can also adapt to support plates 8 with different widths, lift and fix support plates 8 with different widths. When the support plate 8 is idle, the grid 101 can be pulled out from the side of each support plate 8 to clean the corresponding filter screen 102, and then the grid 101 can be reset.

[0030] In summary, the electric conveyor belt 4 is used to transfer the detachable supporting plate 8 and the filter on it. When the supporting plate 8 moves to the cutting processing area, after lifting the supporting plate 8, the supporting plate 8 is evacuated, and then the filter is fixed comprehensively and evenly, thereby avoiding the displacement of the filter due to the vibration of the electric conveyor belt 4 and the vibration of the supporting plate 8 during the cutting process, resulting in a decrease in cutting accuracy. After the cutting is completed, the supporting plate 8 is no longer evacuated, and then the supporting plate 8 is placed back on the electric conveyor belt 4, and then the supporting plate 8 is transferred away. Then, the next supporting plate 8 can be fixed, and the filter on it can be cut. The cutting process is continuous. When this equipment is used in combination with an assembly line, the automation degree is high and the processing efficiency is high.

[0031] The second embodiment On the basis of the first embodiment, according to Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, it further includes a conduit 201 and an air gun 202; the three-axis manipulator 5 is connected with the conduit 201; the conduit 201 is fixedly connected with the protective shell 3; the lower part of the conduit 201 is communicated with the air gun 202.

[0032] The working steps of the above embodiment are as follows: On the basis of the first embodiment, considering that a large amount of heat will be generated during the cutting of the filter, which will cause local expansion of the cutting end face of the filter, and the thermal stress generated in the cutting area may cause cracks in this area and a decrease in material strength. Therefore, the conduit 201 is connected to an external air pump, and air is sprayed out through the conduit 201 and the air gun 202. During the process of the laser cutting head 6 moving for cutting, the air sprayed out by the air gun 202 blows the cutting area of the filter to cool the cutting area, effectively avoiding the problems of crack generation and material strength decrease caused by the thermal stress generated in the cutting area.

[0033] The third embodiment On the basis of the second embodiment, according to Figure 1 , Figure 2 and Figure 11As shown, it further includes a sleeve 301, a support ring 302, an elastic member 303 and a pin rod 304; a sleeve 301 is fixedly connected in each suction hole 8001; there are a plurality of annular gaps left between each sleeve 301 and the inner wall of the corresponding suction hole 8001; a support ring 302 is fixedly connected in each suction hole 8001; four equally spaced elastic members 303 are fixedly connected to each support ring 302; the elastic member 303 is a spring; all the elastic members 303 on each support ring 302 are commonly fixedly connected to a pin rod 304; a groove is formed in the middle of the pin rod 304, and a plurality of equally spaced side holes 30401 are formed in the side wall of the groove; each pin rod 304 is slidably connected to a sleeve 301.

[0034] Based on the second embodiment, when cutting and processing filter plates of different sizes, when the size of the filter plate is small, the filter plate cannot cover the upper surface of the supporting plate 8, that is, the filter plate cannot completely block the suction holes 8001. Therefore, when evacuating the supporting plate 8, a large amount of external air enters the inner cavity of the supporting plate 8 from the suction holes 8001, resulting in a decrease in the adsorption force of the supporting plate 8, and thus a decrease in the fixing effect on the filter plate. The filter plate is prone to displacement, affecting the cutting accuracy of the filter plate. Therefore, a pin rod 304 is provided in each suction hole 8001. The initial state of the pin rod 304 is higher than the upper surface of the supporting plate 8. When placing the filter plate on the surface of the supporting plate 8, the filter plate presses down the pin rod 304, synchronously compressing the corresponding elastic member 303. The annular gap between the sleeve 301 and the side wall of the suction hole 8001 communicates with the corresponding side hole 30401, and the inner cavity of the supporting plate 8 communicates with the corresponding side hole 30401. As Figure 12 shown, therefore, the air in the inner cavity of the supporting plate 8 is evacuated. When the inner cavity of the supporting plate 8 is in negative pressure, the supporting plate 8 can stably adsorb and fix the filter plate thereon, and then the filter plate can be cut and processed. The generated debris enters through the annular gap between the sleeve 301 and the side wall of the suction hole 8001, and then enters the inner cavity of the supporting plate 8 from the side hole 30401. The filter screen 102 in the inner cavity of the supporting plate 8 filters the debris to prevent the debris from entering the external air pump.

[0035] As can be seen from the above working process, according to the specification size of the filter in the current production batch, the suction pressure of the external air pump on the hollow plate 14 is adaptively adjusted, so that while the negative pressure generated in the cavity of the supporting plate 8 adsorbs and fixes the filter, it also balances the rebound force of all the elastic members 303 connected to the pin 304 pressed by the filter. That is, when the size of the filter on the supporting plate 8 is smaller than the plate size of the supporting plate 8, the elastic member 303 in each suction hole 8001 not under the filter will push the corresponding pin 304 upward, and the lower part of the pin 304 contacts the sleeve 301. Thus, the lower part of the pin 304 will block the annular gap between the sleeve 301 and the side wall of the suction hole 8001, and the corresponding side hole 30401 will be blocked by the inner wall of the sleeve 301. At this time, the corresponding suction hole 8001 will not suck air from the outside. By reverse reasoning, it can be known that this device can effectively fix filters of different sizes, and the position of the pin 304 not pressed by the filter will not suck air from the outside, effectively avoiding air leakage in the cavity of the supporting plate 8, resulting in a decrease in the suction force of the supporting plate 8 on the filter, a decrease in the fixing effect on the filter, displacement of the filter, and a decrease in the cutting accuracy of the filter.

[0036] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
