The device realizes independent dust collection of each area through partition dust removal. Based on the original dust removing equipment. The device is improved as follows:
firstly, a dust removing mechanism 1 is arranged on a side wall adjacent to a dust collecting area 5, and the dust removing mechanism 1 is used for collecting dust in the divided area. In this arrangement, the central post 41 and the spacer posts 42 are first divided into a plurality of small dust suction areas, so that dust suction in each area is not affected. And the dust removal efficiency in a single area is improved.
And secondly, controlling the start and the end of the dust collection process by utilizing the sliding relation of the dust collection plate 11 and the sealing plate 12. The sliding of the sealing plate 12 is controlled by the cylinder 3, and when the sealing cover 23 is aligned with the dust suction hole 111, the dust suction hole 111 is closed, and the dust suction is stopped. Otherwise, dust collection is started.
Thirdly, the dust collection area 14 is always in a negative pressure state, so that the sealing cover 23 is moved away from the dust collection area, dust is automatically sucked due to the negative pressure, and the dust is removed by matching with opened dust collection equipment. The arrangement reduces the starting suction force and saves power consumption.

step 1: and finding a zero point. And adjusting the position of the laser head to finish focusing, and correcting the working zero point according to the body zero point and the position to be processed.
Step 2: and (5) preparing for dust removal. The dust suction device is opened to ensure that the dust suction area 14 of each dust removing mechanism 1 is in a negative pressure state compared with the external atmospheric pressure. The dust suction hole 111 on the dust removing plate 11 is determined to correspond to the sealing plate 23, and the dust removing mechanism 1 is in an unopened state. Ready to begin laser machining.
Step 3: judging coordinates for the first time; after the laser head is turned on, laser machining is started. At this time, the X coordinate of the laser head is judged to determine which column it belongs to, i.e., the odd-numbered column or the even-numbered column.
Step 4: judging the coordinates for the second time; and judging the Y coordinate of the laser head, judging which row the laser head belongs to, screening according to the X coordinate in step3, and determining the final area in a cross mode. And starting the dust removal mechanism 1 of the corresponding area at the moment, and performing dust removal in cooperation with laser processing.
Step 5: subsequent dust removal; when the laser head is closed, if the body guide rail operates, the collector transmits the information of the operation of the guide rail back to the central controller, so that the dust removing mechanisms 1 of the fifth partition 55, the sixth partition 56, the seventh partition 57 and the eighth partition 58 in the feeding and discharging area are opened at the same time, and any one of the dust removing mechanisms 1 in operation in the first partition 51, the second partition 52, the third partition 53 and the fourth partition 54 in the processing area is closed. If the laser head is turned on again, the dust removing mechanism 1 of the fifth partition 55, the sixth partition 56, the seventh partition 57 and the eighth partition 58 is stopped, and the steps in step3 and step4 are repeated. When the processing is finished, the bed can be changed by driving the body guide rail, and the position of the workpiece can be moved so as to meet the requirement of the feeding and discharging process. And finally performing dust removal cleaning on the machined workpiece in the feeding and blanking area. In the case where the laser head is turned off and the guide rail is operated simultaneously, the dust removing mechanisms 1 of the fifth, sixth, seventh and eighth divisions 55, 56, 57 and 58 are simultaneously opened. The judgment and control of the closing of the dust removing mechanism 1 of the fifth subarea 55, the sixth subarea 56, the seventh subarea 57 and the eighth subarea 58 are judged by the opening of the laser head, and if the laser head is opened, the guide rail body is already in place, so that the judgment and the collection are not repeated, and the information redundancy degree is reduced.
The coordinate frequency is adopted during dust removal, and the following method is adopted:
and Step1, judging for the first time, selecting a time period T, taking the coordinate point of the laser head at the moment at intervals of the time period T, recording △ X and △ Y of the laser head in the time period T, and judging whether the area is changed.
Step 2: sampling and analyzing for multiple times; and sampling for multiple times according to the time T to obtain the probability C of the changed region.
Step 3: judging for the second time; if C is less than 5%, the sampling time is used as the final sampling time, and the sampling frequency is 1/T. If C is more than or equal to 5 percent, then the sampling time is shortened to T/2, the subsequent operation is the same as the operation when the sampling time is T, until C is less than 5 percent under certain sampling time, and the corresponding sampling frequency is obtained, namely the dedusting sampling frequency of a certain corresponding program.
The adoption of the coordinate point can influence the opening and closing of the dust removing device, thereby influencing the dust removing degree. The corresponding sampling frequency should be set for each corresponding machining program, more accurate coordinate moving sampling is obtained by continuously shortening the sampling time, the opening and closing of the dust removal device can be better controlled, and the method is suitable for large-batch machining of workpieces.

When the sealing cover 23 is moved to the spaced area 112, the dust removing hole 111 is not blocked so that the dust removing process is not hindered. The width of the sealing cover 23 is larger than that of the dust removing hole 111, so that the sealing cover 23 can completely seal and shield the dust when the dust removing process is not carried out, and a dust collecting area 14 without air pressure communication with the outside is constructed.
Fig. 5 is a first directional structural view of the dust removing plate, fig. 6 is a second directional structural view of the dust removing plate, and fig. 7 is a side view of the dust removing plate, and as shown in fig. 5 to 7, the sealing plate 2 includes: a connecting section 21 fixed on the connecting rod of the cylinder 3, and a sliding section 22 connected between the adjacent sealing covers 23.
