DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present invention proposes a laser cutting vaporized ejecta capture assembly, comprising a first mounting frame 1, a first baffle 2, a second mounting frame 3, a magnetic attraction assembly 4 and a rolling assembly 5, for example, Figure 1 and Figure 2 shown.

[0048] Specifically, the first mounting frame 1 includes a housing 7 and a conical plate 8. Figure 3 As shown; the shell 7 is configured as an annular columnar structure, and a first cavity 701 is configured inside the shell 7; the bottom surface of the first cavity 701 is configured as an inclined surface 704, and the side of the inclined surface 704 close to the central axis of the shell 7 is higher than the side away from the central axis of the shell 7; the conical plate 8 is vertically arranged, and the outer ring of the conical plate 8 is fixedly connected to the inner ring of the shell 7.

[0049] A plurality of groups of feed holes 702 are provided on the inner ring side wall of the shell 7, and the plurality of groups of feed holes 702 are all connected to the first cavity 701; the plurality of groups of feed holes 702 are arranged at equal intervals along the central axis of the shell 7, and the two ends of the bottom surface of the lowest group of feed holes 702 are respectively located in the same plane as the inclined surface 704 and the upper surface of the conical plate 8; the plurality of groups of feed holes 702 are arranged at equal intervals along the central axis of the shell 7, and a plurality of groups are arranged in a circular array on the inner ring side wall of the shell 7; through the above structural arrangement, the debris falling on the conical plate 8 will slide along the upper surface of the conical plate 8 into the first cavity 701, and the debris collection is more comprehensive.

[0050] A plurality of groups of discharge holes 703 are provided on the outer ring side wall of the shell 7, and the plurality of groups of discharge holes 703 are connected to the first cavity 701; the plurality of groups of discharge holes 703 are arranged in a circular array, and the bottom surface of each group of discharge holes 703 is located in the same plane as the inclined surface 704; through the above structural arrangement, the debris accumulated in the first cavity 701 can slide out from the discharge holes 703 along the inclined surface 704 to a preset position, making it more convenient to clean the debris.

[0051] A connecting pipe 9 is also provided on the outer side wall of the housing 7 , and one end of the connecting pipe 9 is connected to the top of the first cavity 701 .

[0052] The first partition plate 2 is an annular plate arranged at an angle, and the side of the first partition plate 2 close to its own central axis is higher than the side away from its own central axis; the inner and outer circles of the first partition plate 2 are respectively fixedly connected to the two side walls of the first cavity 701; the horizontal heights of the inner and outer circles of the first partition plate 2 are respectively higher than the horizontal heights of the feed hole 702 and the discharge hole 703; the first partition plate 2 is used to guide and limit the debris entering the first cavity 701 through the feed hole 702, so that it falls on the inclined surface 704.

[0053] Several groups of the second mounting frames 3 are arranged in a circular array on the outer ring of the shell 7, and each group of the second mounting frames 3 is respectively located between two adjacent groups of discharge holes 703; several groups of the magnetic suction components 4 are arranged in a circular array, each group of the magnetic suction components 4 is respectively installed between two adjacent groups of second mounting frames 3, and each group of the magnetic suction components 4 can respectively block one group of discharge holes 703; the second mounting frames 3 are used to install the magnetic suction components 4, and the magnetic suction components 4 are used to attract debris that enters the discharge hole 703 through the feed hole 702 and the first cavity 701 to prevent it from splashing.

[0054] The rolling assembly 5 is disposed at the lower end of the first mounting frame 1; the rolling assembly 5 is used to perform planar movement of the device.

[0055] Exemplarily, before use, the first mounting bracket 1 is placed under the cutting plate and in contact with the plate to be cut; when the laser cutting equipment cuts the plate, the sparks spattered from the plate and the debris accompanying the sparks will successively enter the first cavity 701 through the conical plate 8 and several groups of feed holes 702; the debris spattered to a high place will collide with the first partition plate 2, and fall to the inclined surface 704 after being guided by the inclined first partition plate 2; the debris spattered to a low place will directly collide with the magnetic suction component 4 and be adsorbed by the magnetic suction component 4.

[0056] When it is necessary to remove the debris in the first cavity 701 and on the magnetic component 4, the magnetic component 4 can be pulled out, so that the debris adsorbed on the magnetic component 4 is scraped off by the discharge hole 703 and falls onto the inclined surface 704, and finally falls into the pre-set collection box through the inclined surface 704.

[0057] Through the coordinated use of the first mounting frame 1, the first partition plate 2, the second mounting frame 3 and the magnetic attraction assembly 4, the device has a simple structure, low manufacturing cost, and can comprehensively collect debris sputtered during laser cutting, thus being more practical.

[0058] Specifically, Figure 4 As shown, the central axis directions of each group of the feed holes 702 and each group of the discharge holes 703 coincide with a group of radii of the shell 7 respectively; a number of groups of feed holes 702 are arranged at equal intervals along the central axis direction of the shell 7, wherein the axis directions are parallel to the central axis of a group of discharge holes 703 respectively.

[0059] By arranging a plurality of groups of feed holes 702 at equal intervals along the central axis of the shell 7, wherein the axial directions are parallel to the central axes of a group of discharge holes 703, when debris is splashed into the feed holes 702, it will directly pass through the discharge holes 703 and collide with the magnetic suction component 4, thereby preventing the debris from splashing in the first mounting frame 1 and affecting the debris collection effect, and the debris collection is safer and more stable.

[0060] The upper and lower end surfaces of each group of the feed holes 702 are symmetrically inclined with their own central axis as the center; and the radial height of each group of feed holes 702 away from the central axis of the shell 7 is smaller than the radial height of its own end close to the central axis of the shell 7.

[0061] For example, the debris generated during laser cutting may directly pass through the feed hole 702 into the first cavity 701 , or collide with the inclined upper and lower end surfaces of the feed hole 702 and enter the first cavity 701 due to the inclined upper and lower end surfaces of the feed hole 702 .

[0062] By setting the radial height of each group of feed holes 702 away from one end of the shell 7's central axis to be smaller than its own radial height close to one end of the shell 7's central axis, the debris generated during laser cutting can more easily enter the first mounting frame 1 during sputtering, thereby making the debris collection more comprehensive and the collection effect better.

[0063] The first partition plate 2 is provided with a plurality of groups of vent holes 201 at equal intervals along its own radial direction. Figure 5 As shown; several groups of vent holes 201 arranged at equal intervals are arranged in a circular array on the first partition plate 2.

[0064] For example, Figure 6As shown, the first partition plate 2 divides the first cavity 701 into a second cavity 7011 and a third cavity 7012 from top to bottom; the connecting pipe 9 is connected to the second cavity 7011, and the feed hole 702 and the discharge hole 703 are both connected to the third cavity 7012.

[0065] The debris collection device also includes a gas collection device (not shown in the figure), which includes a collection box, an air pump and an air pipe. The output end and the input end of the air pump are connected to the connecting pipe 9 and the collection box respectively through the air pipe.

[0066] Exemplarily, when the laser cutting device is in use, the sputtered debris will enter the third cavity 7012, and the exhaust gas generated during cutting and the gasification products generated during plate cutting will be absorbed by the gas collection device.

[0067] By opening a vent hole 201 on the first partition plate 2, the first cavity 701 is divided from top to bottom into a second cavity 7011 and a third cavity 7012 by the first partition plate 2; the second cavity 7011 is connected to a gas collection device for collecting exhaust gas; the third cavity 7012 is used to collect debris generated during cutting. The device can collect the gas and debris generated during laser cutting separately, and at the same time can prevent harmful substances from entering the external environment, making it safer to use.

[0068] Specifically, Figure 7 As shown, each row of the plurality of groups of vent holes 201 is arranged at equal intervals along the radial direction of the first partition plate 2, wherein the axis is located exactly in the middle of the axis of two adjacent groups of feed holes 702 or two columns of feed holes 703.

[0069] For example, when the laser cutting device is in use, the debris that enters the upper position of the third cavity 7012 will touch the position of the first partition plate 2 where no vent hole 201 is provided, and fall on the inclined surface 704 under the influence of the position.

[0070] By setting the central axis of each column of air holes 201 to be located in the middle of the central axis of two adjacent groups of feed holes 702 or two columns of feed holes 703, the debris generated by the laser cutting equipment during cutting will not touch the air holes 201 on the first partition 2 when entering the first cavity 701, so that the device can guide the debris while collecting the exhaust gas, and at the same time does not affect the guiding effect of the debris. The structure is simple, the manufacturing cost is low, and it is more convenient to use.

[0071] The second mounting frame 3 includes a first conical plate 10, a fixed plate 11 and a second partition plate 12; the first conical plate 10 is arranged on the outer ring side wall of the shell 7, and the first conical plate 10 is located directly below two adjacent groups of discharge holes 703; the fixed plate 11 is vertically arranged at the end of the first conical plate 10 away from the shell 7, and the fixed plate 11 and the outer ring side wall of the shell 7 are parallel to each other and have a gap; the second partition plate 12 is arranged between the fixed plate 11 and the outer ring side wall of the shell 7, and two groups of left-right symmetrical mounting cavities 301 are formed between the first conical plate 10, the fixed plate 11, the second partition plate 12 and the outer ring side wall of the shell 7.

[0072] The magnetic attraction assembly 4 includes a plurality of groups of magnet blocks 13, such as Figure 8 As shown; the lower ends of each group of the magnet blocks 13 are fixedly connected to a group of clamping blocks 14, and the side walls of the two relative positions are located in the same plane; the two side ends of the magnet blocks 13 and the clamping blocks 14 can be respectively clamped in a group of mounting cavities 301, and one side of both can be movably fitted with the outer ring side wall of the shell 7.

[0073] Illustratively, the debris generated by the laser cutting equipment during use will enter the third cavity 7012, and the debris at the lower position will be adsorbed on the magnet block 13, and the rest will accumulate on the inclined surface 704; when collecting and removing the debris in the third cavity 7012, the magnet block 13 is pushed upward, and the debris adsorbed on the magnet block 13 will be stuck by the upper end of the discharge hole 703 until the magnet block 13 completely leaves the discharge hole 703, and the clamping block 14 is fitted with the upper end of the discharge hole 703. At this time, the debris stuck at the upper end of the discharge hole 703 will fall on the inclined surface 704 due to the loss of adsorption of the magnet block 13; at this time, the debris on the inclined surface 704 will slide into the pre-set collection box.

[0074] The magnetic attraction assembly 4 is formed by arranging the magnet block 13 and the clamping block 14 up and down. The device is more convenient and quick to remove the debris adsorbed on the magnet block 13, does not require the assistance of other objects, and has strong structural integrity.

[0075] The rolling assembly 5 includes a third mounting frame 15 and a ball 16. Fig. 9 As shown; the third mounting frame 15 is fixedly mounted on the lower end of the first mounting frame 1, and a plurality of groups of the balls 16 are arranged in a ring array and movably connected to the lower end of the third mounting frame 15.
