Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting machines and relates to a plate feeding device, in particular to an anti-adhesion automatic sheet feeding device for plate laser cutting. Background Art

[0002] The sheet metal laser cutting equipment is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Laser cutting replaces the traditional mechanical knife with an invisible beam, and has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth incision, and low processing cost. It will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow; the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.

[0003] When laser cutting plates (iron plates, stainless steel plates, cold-rolled plates, wooden plates, aluminum plates, stone plates, etc.), the plates need to be transported to the loading station of the laser cutting machine for plate processing. The traditional manual handling is inefficient, and the existing loading equipment still requires the cooperation of multiple operators; it is not possible to efficiently perform sheet processing, stable transportation and plate alignment.

[0004] Based on this, we propose an anti-adhesion automatic sheet feeding device for plate laser cutting. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the existing technology and to propose an anti-adhesion automatic sheet separation and feeding device for laser cutting of plates. The technical problem to be solved by the invention is: how to achieve stable sheet separation, efficient transportation and rapid alignment of stacked laser-cut plates, ensure the initial accurate positioning of the plates, and have a thickness measurement function.

[0006] The purpose of the present invention can be achieved by the following technical solutions: An anti-adhesion automatic sheeting and feeding device for plate laser cutting comprises a positioning bracket, a processing platform and a plate receiving platform located at the rear side of the processing platform, the processing platform and the plate receiving platform are located on the inner side of the positioning bracket, the side of the processing platform is provided with a lifting and positioning mechanism penetrating therethrough, the side of the plate receiving platform is provided with a thickness measuring mechanism, the positioning bracket is provided with a shifting mechanism which is arranged for transmission therewith, the shifting mechanism is provided with a suction cup transporting mechanism, a lifting plate and sheeting mechanism is provided at the side top corner of the suction cup transporting mechanism, a plurality of positioning and oblique pushing mechanisms are provided on the front side of the suction cup transporting mechanism, the lifting and positioning mechanism, the thickness measuring mechanism and the lifting plate and sheeting mechanism are located on the same side, and the lifting plate and sheeting mechanism, the suction cup transporting mechanism and the positioning and oblique pushing mechanism are located above the processing platform and the plate receiving platform.

[0060] The working principle of the present invention is as follows: a number of plates to be processed are stacked on the platform frame 53, and the stacked plates are adsorbed together. The shift mechanism 9 moves laterally on the adjustment bracket 6, and the shift mechanism 9 can drive the suction cup transport mechanism 7 to move up and down vertically, that is, the suction cup transport mechanism 7 can move laterally and vertically, that is, the transverse motor adjustment seat 25 installs the transverse motor 23 and adjusts the position of the transverse motor 23, the output shaft of the transverse motor 23 drives the transverse gear to rotate, the transverse gear is engaged with the transverse rack 15, and drives the transverse slide 21 to slide on the two transverse guide rails 16, and the auxiliary gear 18 is engaged with the transverse rack 15 to ensure that the transverse slide 21 moves horizontally stably; the vertical motor adjustment seat 30 installs the vertical motor 19 and adjusts the position of the vertical motor 19, the output shaft of the vertical motor 19 drives the vertical gear to rotate, the vertical gear is engaged with the vertical rack 27, and drives the two vertical guide rails 26 to slide vertically on the transverse slide 21, that is, drives the vertical frame rod 22 to slide vertically up and down, and the auxiliary gear 2 is engaged with the vertical rack 27 to ensure that the vertical frame rod 22 moves vertically stably; The shift mechanism 9 drives the suction cup transport mechanism 7 to move horizontally to the top of the sheet material receiving platform 4, which is the initial position. The shift mechanism 9 then drives the suction cup transport mechanism 7 to move downward, and the suction cup transport mechanism 7 contacts the uppermost sheet material on the sheet material receiving platform 4. At this time, the lifting plate suction cup 1 46 and the lifting plate suction cup 2 48 contact the top corner of the upper end surface of the sheet material. The lifting plate suction cup 1 46 and the lifting plate suction cup 2 48 are both matched with the multi-vent pipe joint 51 at the corresponding position. The lifting plate suction cup 1 46 and the lifting plate suction cup 2 48 negatively absorb the top corner of the sheet material. The telescopic end of the lifting plate cylinder 45 drives the lifting plate connecting rod 47 to rise, thereby driving the lifting plate suction cup 1 46 and the lifting plate suction cup 2 48 to rise, and lift the top corner of the sheet material for sheet separation. At this time, the suction cup transport mechanism 7 also absorbs the plate, that is, the air pump 50 compresses the air → supplies → vacuum generator 37, the vacuum generator 37 outlet → vacuum solenoid valve 36 → multi-way solenoid valve 38 → multi-way air pipe joint 51 is connected to the transport suction cup 34, At the same time, the shifting mechanism 9 drives the suction cup transporting mechanism 7 to move upward, pulls up the top plate, and moves it to the thickness measuring mechanism 3. At this time, the plate is located between the upper measuring rod 59 and the lower measuring rod 61. The telescopic end of the detection electric push rod 56 extends, driving the fixed seat 62 to extend, thereby driving the detection encoder 57, the upper top plate 58, the upper measuring rod 59, the lower measuring rod 61, the limit baffle 63 and the reset torsion spring 64 to move. The upper measuring rod 59 and the lower measuring rod 61 drive the two rolling shaft wheels 60 thereon to move. The two rolling shaft wheels 60 clamp the plate, and the lower rolling shaft wheel 60 moves downward. The rotating shaft of the lower measuring rod 61 rotates downward, and the reset torsion spring 64 Under the force, the rotating shaft of the lower measuring rod 61 drives the rotating shaft of the detection encoder 57 to rotate, so that the detection encoder 57 obtains the thickness of the plate according to the rotation angle of the rotating shaft. If the thickness is greater than the thickness of one plate, it means that the plate adsorbed at this time is greater than one plate, and the shifting mechanism 9 needs to drive the suction cup transport mechanism 7 to move downward, release the adsorption of the plate by the lifting plate separation mechanism 5 and the suction cup transport mechanism 7, put the plate back to its original position, re-adsorb, pull up and perform thickness detection, until the thickness detected by the thickness measuring mechanism 3 is the thickness of one plate. If the thickness is still greater than the thickness of one plate after three thickness detections, human intervention is required to manually separate the uppermost plate; The lifting plate separation mechanism 5 cooperates with the suction cup transport mechanism 7 to suck up a sheet of plate, and then the shifting mechanism 9 drives the suction cup transport mechanism 7 to move horizontally to just above the processing platform 1, and then the shifting mechanism 9 drives the suction cup transport mechanism 7 to move downward until the sheet of plate is placed on the processing platform 1, that is, the sheet of plate is placed on the support plate brush 68, and the support plate brush 68 is bent, so that the sheet of plate is against a plurality of universal balls 67, and the suction of the suction cup transport mechanism 7 and the lifting plate separation mechanism 5 on the sheet of plate is released; The oblique thrust cylinder 41 rotates inside the oblique thrust mounting seat 39, and the angle adjustment plate is slidably adjusted. The angle adjustment plate abuts against one side end of the oblique thrust cylinder 41 to adjust the angle of the oblique thrust cylinder 41. At this time, the cylinder tension spring 40 is stretched to pull the other side end of the oblique thrust cylinder 41 to limit the angle of the oblique thrust cylinder 41. Then the positioning oblique push mechanism 8 absorbs the plate and pushes the plate obliquely to the right rear on the processing platform 1, that is, the oblique push suction cup 43 abuts against the upper end surface of the plate, and the oblique push suction cup 43 cooperates with the multi-ventilation pipe joint 51 at the corresponding position, and the oblique push suction cup 43 is adsorbed on the upper end surface of the plate. The two ends of the suction cup reset spring 44 respectively abut on the mounting block 42 and the oblique push suction cup 43, which are used to buffer the oblique push suction cup 43. The telescopic end of the oblique push cylinder 41 drives the mounting block 42 to move, thereby driving the oblique push suction cup 43 to move, and then drives the plate to move on a number of universal ball bearings 67, so that the narrower side of the plate abuts against the jacking positioning mechanism 2, that is, the telescopic end of the jacking cylinder 73 is telescoped, thereby driving the main body of the jacking cylinder 73 to rise and fall in the reverse direction, and the jacking cylinder 73 drives the mounting vertical plate 75 to rise and fall, that is, drives the proximity sensor 74 and the two The bearing seat 76, the sliding limit shaft 78, the positioning rod 77, the swing rod 79 and the positioning ejector rod 72 are lifted and lowered synchronously, so that the swing rod 79 rises and falls from the avoidance through hole, and then drives the positioning ejector rod 72 to rise and fall. After the plate hits the positioning ejector rod 72, the swing rod 79 is pushed to rotate on the two bearing seats 76, so that the swing rod 79 slides on the sliding limit shaft 78. The swing rod 79 presses the ejection spring, and the swing rod 79 drives the positioning rod 77 to move. The positioning rod 77 hits the proximity sensor 74, controls the positioning oblique push mechanism 8 to stop the oblique push of the plate, completes the short side positioning of the plate, and after the plate leaves the positioning ejector rod 72 for laser cutting, the ejection spring drives the swing rod 79 to reset. At this time, the positioning rod 77 is separated from the proximity sensor 74, ensuring that the positioning oblique push mechanism 8 is controlled to stop the oblique push of the plate next time. After the alignment of the plates is completed, the adsorption of the plates by the oblique push suction cup 43 is released, and the telescopic end of the oblique push cylinder 41 is retracted, driving the oblique push suction cup 43 to reset; At the same time, the wider side of the plate abuts against the plate longitudinal material moving device to position the plate, that is, to lock the plate in the initial position of the processing platform 1; After the material is discharged, the shifting mechanism 9 drives the suction cup transporting mechanism 7 to move upward and horizontally to the top of the sheet material placing platform 4 for resetting.

[0061] In summary, through the cooperation of the positioning bracket 6 and the shifting mechanism 9, the suction cup transport mechanism 7 is driven to move horizontally and vertically, so as to transport and transfer the plate; the plate is placed on the plate supporting platform 4, and the suction cup transport mechanism 7 cooperates with the lifting plate and separating mechanism 5, and at the same time, the lifting plate and separating mechanism 5 cooperates with the permanent magnet block 54 to achieve stable sheet separation of the plates stacked on the plate supporting platform 4; the thickness of the adsorbed plate is measured by the thickness measuring mechanism 3 to ensure that one plate to be laser cut is pulled up each time; the positioning oblique pushing mechanism 8 and the processing platform 1 are used to achieve stable oblique pushing and placing of the plate, so as to quickly place and align the plate; the processing platform 1 cooperates with the lifting and positioning mechanism 2 and the lifting electric push rod 71 to align and place the plate to ensure accurate positioning of the plate, that is, to lock the plate in the initial position of the processing platform 1, so as to facilitate subsequent laser cutting of the plate.
