[0031] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0033] See also Figure 2 , Figure 4 As shown, the utility model is a dust suction device for cutting a circuit board, comprising a cutting table 1, a supporting device 2 is arranged on the top of the cutting table 1, a cutting device 3 is slidably connected to the top of the supporting device 2, a column 4 is fixedly installed on the top of the cutting table 1, a driving mechanism 5 is arranged on the outer surface of the column 4, a threaded block 6 is threadedly connected to the output end of the driving mechanism 5, a hollow slide 7 is fixedly connected to the outer surface of the column 4, a lifting mechanism 8 is arranged on the top of the hollow slide 7, the output end of the lifting mechanism 8 is rotatably connected to the top of the threaded block 6, the output end of the lifting mechanism 8 is threadedly connected to the lifting sleeve block 9, and a dust suction device 10 is arranged on one side of the lifting sleeve block 9.

[0034] When it is necessary to cut the circuit board, start the driving mechanism 5 to drive the threaded block 6 to move on the inner side of the column 4. When the threaded block 6 is driven to move, the top of its lifting mechanism 8 is also driven to slide on the outside of the hollow slide 7. At this time, start the dust suction device 10 to generate suction force inside it. When the cutting device 3 is cutting, the threaded block 6 is driven to drive the lifting mechanism 8 to move laterally. At the same time, the lifting mechanism 8 starts to drive the lifting sleeve block 9 to move, thereby driving the dust suction device 10 to move longitudinally on one side of the lifting mechanism 8, so that the dust suction device 10 is driven to move laterally from the initial end of one group of columns 4 during operation, and simultaneously moves longitudinally to one side of the cutting device 3 to suck dust.

[0035] The utility model connects the bottom end of the lifting mechanism 8 with the top of the threaded block 6 by rotation, so that when the driving mechanism 5 drives the threaded block 6 to move laterally outside the lifting mechanism 8, it drives the lifting mechanism 8 on the top to move synchronously on the outside of the hollow slide 7. At the same time, after the lifting mechanism 8 is started, it drives the lifting sleeve 9 and the dust collecting device 10 to move longitudinally on the outside of the lifting mechanism 8, so that the dust collecting device 10 can move up and down while moving laterally on one side of the cutting device 3 to increase the range of dust collection at the cutting position of the cutting device 3, so as to prevent the dust with a high lift or a low falling position from being incompletely absorbed, thereby improving the dust collection effect during the cutting process, and preventing the dust from flying into the air or partially falling into the dead corner of the cutting table and being difficult to clean.

[0036] In one embodiment, for the above-mentioned driving mechanism 5 , the driving mechanism 5 includes a driving motor 501 , an output end of the driving motor 501 is fixedly connected with a driving screw 502 , and the driving screw 502 is threadedly connected to the thread block 6 .

[0037] By fixing the driving motor 501 on one of the groups of columns 4, when the driving motor 501 is started, it drives the driving screw 502 to rotate. When the driving screw 502 rotates, it drives the threaded block 6 to move outside it and drives the lifting mechanism 8 on the top to slide and move on the outside of the hollow slide 7.

[0038] By driving the motor 501 in cooperation with the driving screw 502 to rotate and drive the threaded block 6 to move, and in cooperation with the lifting mechanism 8, the lifting mechanism 8 can provide a lateral movement driving force while enabling the lifting mechanism 8 to limit the lateral displacement path of the threaded block 6, thereby limiting the lateral and longitudinal paths of the dust collection device 10 during the dust collection operation, thereby facilitating effective dust collection operations on the cutting position of the cutting device 3.

[0039] In one embodiment, for the above-mentioned lifting mechanism 8, the lifting mechanism 8 includes a horizontal slide plate 801, a lifting motor 802 is fixedly installed on the top of the horizontal slide plate 801, and a lifting screw 803 is provided at the output end of the lifting motor 802, and the lifting screw 803 is threadedly connected to the inner wall of the lifting sleeve block 9.

[0040] The horizontal slide plate 801 is hollow and slidingly connected to the outside of the hollow slideway 7. The bottom of the lifting screw 803 is connected to the top of the threaded block 6. When the lifting screw 803 is driven by the threaded block 6 to move laterally, the lifting motor 802 is started synchronously to drive the lifting screw 803 to rotate to drive the lifting sleeve 9 to move longitudinally and lift outside the lifting screw 803.

[0041] By setting the cross slide 801 to be hollow and cooperating with the hollow slide 7, a lateral displacement circulation space can be provided for the lifting screw 803. When the lifting screw 803 is driven to move by the threaded block 6, it can drive the lifting sleeve block 9 and the dust collection device 10 to move longitudinally synchronously after simultaneous operation, thereby providing the dust collection device 10 with flexible lateral and longitudinal simultaneous movement driving force, thereby making the dust collection operation of the dust collection device 10 more flexible.

[0042] In one embodiment, for the dust suction device 10 , the dust suction device 10 includes a dust suction fan 101 , a bearing sleeve 102 is fixedly mounted on the outer surface of the dust suction fan 101 , and one side of the bearing sleeve 102 is fixedly connected to the lifting sleeve 9 .

[0043] One side of the bearing sleeve 102 is fixedly connected to the lifting sleeve block 9, so that the dust suction fan 101 is supported on one side of the lifting sleeve block 9. When the lifting sleeve block 9 is driven to move, the bearing sleeve 102 and the dust suction fan 101 are driven to move. At the same time, after the dust suction fan 101 is started, the suction force generated inside it absorbs the dust scattered around the cutting device 3, so that the dust suction fan 101 has a wider operating range and a better dust suction effect.

[0044] In one embodiment, for the above-mentioned dust suction fan 101, a dust suction hopper 103 is provided on the outer surface of the dust suction fan 101, a dust collecting pipe 104 is fixedly installed on the top of the dust suction fan 101, a sleeve slide 11 is provided on one side of the lifting sleeve block 9, and a limiting rod 12 is fixedly installed on the top of the threaded block 6, and the sleeve slide 11 penetrates and is slidably connected to the outer surface of the limiting rod 12.

[0045] The dust hopper 103 increases the dust entry space at the input end of the dust suction fan 101. At the same time, when the dust suction fan 101 is driven to move, the sleeve slide plate 11 is driven to move synchronously outside the limiting rod 12 to limit the longitudinal displacement of the dust suction fan 101.

[0046] By setting the dust hopper 103 at the suction end of the dust suction fan 101, the wind output can be made more concentrated and the restriction range when the dust is sucked in can be increased, so that the dust can accurately enter the dust suction fan 101 through the dust hopper 103 and be discharged through the dust collecting pipe 104. At the same time, the sliding plate 11 can synchronously slide outside the limiting rod 12 to limit the displacement path of the dust suction fan 101.

[0047] In one embodiment, for the above-mentioned supporting device 2 , the supporting device 2 includes a fixing column 201 , an electric slide rail 202 is fixedly installed on the top of the fixing column 201 , and a sliding sleeve 203 is slidably connected to the outer surface of the electric slide rail 202 .

[0048] The electric slide rail 202 is supported on the inner side of the two sets of fixed columns 201. By supporting the cutting device 3 on one side of the sleeve 203, when the electric slide rail 202 is started, the sleeve 203 can be driven to move laterally outside thereof, so as to provide a lateral displacement driving force for the cutting device 3.

[0049] In one embodiment, for the above-mentioned cutting device 3, the cutting device 3 includes a transverse slide 301, one end of which is fixedly connected to the outer surface of the sleeve 203, the outer surface of the transverse slide 301 is slidably connected to a transverse slider 302, and a laser cutting head 303 is arranged at the bottom of the transverse slider 302.

[0050] The electric slide rail 202 drives the sleeve 203 to move externally, while driving the transverse slide 301 and the transverse slider 302 to move synchronously. At the same time, the transverse slider 302 can slide longitudinally outside the transverse slide 301 to drive the laser cutting head 303 to move, thereby providing the laser cutting head 303 with transverse and longitudinal movement driving force, so that it can flexibly cut the circuit board.

[0051] In one embodiment, for the above-mentioned horizontal slider 302 , a fixing sleeve 13 is fixedly installed on one side of the horizontal slider 302 , a guide tube 14 is provided on the inner wall of the fixing sleeve 13 , and a nozzle 15 is fixedly connected to the bottom of the guide tube 14 .

[0052] When the horizontal slide block 302 moves outside the horizontal slideway 301, it simultaneously drives the fixed sleeve 13 to move, and at the same time connects the guide pipe 14 with the cooling water pipeline, so that the cooling water is transported to the inside of the guide pipe 14. When the laser cutting head 303 performs the cutting operation, the nozzle 15 simultaneously sprays the cooling water in the form of a spray to the cutting position.

[0053] The guide tube 14 is supported on one side of the horizontal slider 302 by the fixing sleeve 13, so that when the laser cutting head 303 is performing laser cutting operation, the guide tube 14 and the nozzle 15 cooperate to transport cooling water mist to the cutting position to cool down the cutting sparks and dust, and prevent the high-temperature dust from being sucked into the dust suction fan 101 and damaging its internal components.

[0054] In one embodiment, for the cutting table 1 , a protective baffle 16 is disposed on the outer surface of the cutting table 1 , and a transparent plate 17 is fixedly mounted on one side of the protective baffle 16 .

[0055] By supporting the protective baffle 16 on the outer side of the cutting table 1 and cooperating with the transparent plate 17, a semi-open blocking effect can be provided on the outer side thereof, thereby reducing the range of dust scattering and making the dust absorption effect on the inner side better.

[0056] In one embodiment, for the cutting table 1 , a positioning plate 18 is disposed on the top of the cutting table 1 .

[0057] The positioning plate 18 is convenient for providing positioning and placement for the circuit board to be cut so that it corresponds to the cutting range of the laser cutting head 303 .

[0058] Through the above technical solution, 1. By rotatably connecting the bottom end of the lifting mechanism 8 with the top of the threaded block 6, when the driving mechanism 5 drives the threaded block 6 to move laterally outside the lifting mechanism 8, it drives the lifting mechanism 8 on the top to move synchronously outside the hollow slide 7. At the same time, after the lifting mechanism 8 is started, it drives the lifting sleeve 9 and the dust collecting device 10 to move longitudinally outside the lifting mechanism 8, so that the dust collecting device 10 can move up and down while moving laterally on one side of the cutting device 3 to increase the range of dust collection at the cutting position of the cutting device 3, so as to prevent the dust with a high lift or a low falling position from being absorbed poorly. A thorough situation occurs, thereby improving the dust collection effect during the cutting process and preventing the dust from flying into the air or falling partially into the dead corners of the cutting table and being difficult to clean; 2. One side of the bearing sleeve 102 is fixedly connected to the lifting sleeve block 9, so that the dust collection fan 101 is supported on one side of the lifting sleeve block 9, so that when the lifting sleeve block 9 is driven to move, the bearing sleeve 102 and the dust collection fan 101 are driven to move, and at the same time, after the dust collection fan 101 is started, the suction force generated inside it absorbs the dust scattered around the cutting device 3, so that the dust collection fan 101 has a wider operating range and a better dust collection effect.
