Description

Technical Field

[0001] The invention relates to the technical field of laser beam processing, and in particular to a double-sided laser drilling and cutting device and method with controllable verticality. Background Art

[0002] Laser cutting and laser drilling are important areas of laser processing. Compared with traditional mechanical processing methods, laser processing has been applied in more and more scenarios with its non-contact, high precision, high collimation effect and high efficiency.

[0003] When drilling and cutting thicker workpieces, as the slits become deeper, more and more plasma gas gathers in the gaps and cannot be discharged smoothly. In order to ensure that the ionized gas generated when the laser cuts the processed material can smoothly overflow from the cutting port, the current common practice is to expand the slit width by opening more slits. When cutting the workpiece in the above manner, as the thickness of the workpiece increases, the number of slits that need to be cut will also increase. This phenomenon easily leads to low efficiency when processing thicker workpieces, large taper of the punched holes, and high slope of the cutting slits.

[0022] 1. The present invention can adjust the positions of two laser components on the front and back sides of the workpiece synchronously through the longitudinal moving component, the power component, the linkage component and the transverse driving component, so that the two laser components can process the same position of the workpiece from both sides at the same time.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0035] As introduced in the background technology, in order to solve the deficiencies in the prior art and the above technical problems, the present application proposes a double-sided laser drilling and cutting device and method with controllable verticality.

[0036] See also Figure 1-Figure 8 A double-sided laser drilling and cutting device with controllable verticality comprises a support frame 1, a longitudinal moving component 2 is arranged on the outer surface of the support frame 1, laser components 3 are symmetrically arranged on the front and back sides of the longitudinal moving component 2, a transverse driving component 4 is arranged inside the longitudinal moving component 2 corresponding to the laser component 3, a linkage component 5 is arranged at the input end of the transverse driving component 4, a power component 6 is arranged on the outer side of the linkage component 5, and a fixing component 7 is arranged inside the support frame 1.

[0037] The fixing assembly 7 is used to fix the processing frame on the support frame 1, the longitudinal moving assembly 2 is used to drive the laser assembly 3 to move longitudinally on the support frame 1, the transverse driving assembly 4 is used to drive the laser assembly 3 to move transversely on the support frame 1, and the power assembly 6 is used to drive the linkage assembly 5, so that the linkage assembly 5 drives the laser assembly 3 through the transverse driving assembly 4;

[0038] When the workpiece is cut, the workpiece is fixed on the support frame 1 by the fixing component 7, and then the longitudinal moving component 2 is driven, so that the longitudinal moving component 2 can drive the two laser components 3 to move longitudinally on both sides of the workpiece. At the same time, the two transverse driving components 4 are driven by the power component 6 through the linkage component 5, so that the transverse driving component 4 drives the two laser components 3 to move transversely on both sides of the workpiece, and the two laser components 3 complete the cutting of the workpiece while moving.

[0039] The longitudinal moving component 2 can make the two laser components 3 move longitudinally synchronously on the front and back sides of the workpiece. At the same time, the power component 6 and the linkage component 5 can make the two transverse driving components 4 drive the corresponding laser components 3 to move laterally synchronously on the front and back sides of the workpiece, so that the two laser components 3 can process the same position of the workpiece from both sides at the same time. The bidirectional processing of the laser component 3 can increase the efficiency of cutting the workpiece by several times. At the same time, since the laser component 3 processes from both sides, the width of the upper and lower slits can be kept consistent, so that the taper and slope of the slits formed during processing are reduced by several times.

[0040] Furthermore, for the above-mentioned longitudinal moving component 2, the longitudinal moving component 2 includes a longitudinal moving frame 201, the longitudinal moving frame 201 is arranged on the outside of the support frame 1, one side of the support frame 1 is rotatably connected with a longitudinal screw 202, the longitudinal screw 202 is threadedly connected to the longitudinal moving frame 201, and a longitudinal motor 203 is fixedly installed on the top of the support frame 1, and the output end of the longitudinal motor 203 is fixedly connected to the longitudinal screw 202.

[0041] By driving the longitudinal motor 203, the longitudinal motor 203 drives the longitudinal movable frame 201 to move longitudinally on the outside of the support frame 1 through the longitudinal screw 202. At the same time, a fixed column is arranged on the side of the support frame 1 opposite to the longitudinal screw 202, and the longitudinal movable frame 201 is movably connected to the fixed column. This arrangement ensures the stability of the longitudinal movable frame 201 when it moves.

[0042] Furthermore, for the above-mentioned laser component 3, the laser component 3 includes a mounting seat 301, which is movably connected to the longitudinal movable frame 201, and the mounting seat 301 is arranged on the front and back sides of the longitudinal movable frame 201, and a laser head body 302 is fixedly installed on one side of the mounting seat 301.

[0043] By sliding the mounting seat 301, the mounting seat 301 can drive the corresponding laser head body 302 to move horizontally on the longitudinal moving frame 201, and the laser head body 302 can emit laser, so that the laser can cut the workpiece. The laser head body 302 is provided with an EOM and a galvanometer system. This setting allows the laser emitted by the laser to be divided into two beams through a beam splitter. The two beams can be shot into the two laser head bodies 302 with the assistance of a reflector and respectively emitted from the bottom ends of the two laser head bodies 302 with the assistance of the corresponding EOM and galvanometer system. At the same time, the galvanometer can adjust the verticality of the laser, so that the laser can achieve highly flexible special-shaped hole processing.

[0044] Furthermore, for the above-mentioned transverse drive component 4, the transverse drive component 4 includes a drive groove 401, and the drive groove 401 is arranged on the front and back sides of the longitudinal movable frame 201. The mounting seat 301 is movably connected to the corresponding drive groove 401, and the internal rotation of the drive groove 401 is connected with a transverse screw 402, and the transverse screw 402 is threadedly connected to the mounting seat 301.

[0045] By driving the transverse screw 402, the transverse screw 402 can drive the mounting seat 301 to move inside the driving groove 401, and the moving mounting seat 301 drives the corresponding laser head body 302 to move horizontally. The above-mentioned driving groove 401 can guide the moving direction of the mounting seat 301, so that the stability of the mounting seat 301 during movement can be guaranteed.

[0046] Furthermore, for the above-mentioned linkage component 5, the linkage component 5 includes an installation box 501, the installation box 501 is fixedly connected to the longitudinal movable frame 201, the interior of the installation box 501 corresponds to the transverse screw 402 and is rotatably connected to two linkage rods 502, the outer surface of the linkage rod 502 is fixedly connected to a driving bevel gear 503, the outer surface of the driving bevel gear 503 is meshed with a driven bevel gear 504, the transverse screw 402 is fixedly connected to the driven bevel gear 504, and the outer surface of the linkage rod 502 is provided with a rotating cylinder 505.

[0047] By rotating the rotating cylinder 505, the rotating cylinder 505 can simultaneously drive the two linkage rods 502 to rotate, and the two rotating linkage rods 502 drive the two driven bevel gears 504 to rotate through the corresponding two active bevel gears 503. At this time, the two driven bevel gears 504 simultaneously drive the two transverse screws 402 to rotate, so that the two transverse screws 402 can move the corresponding laser head body 302 longitudinally synchronously. The two transverse screws 402 do not need to be driven by two driving sources, thereby avoiding the reaction time difference generated by the controller in controlling the two driving sources, which causes the two transverse screws 402 to drive the corresponding laser head body 302 to move to the processing position. Deviation occurs.

[0048] Furthermore, for the above-mentioned linkage rod 502, the outer surfaces of the two linkage rods 502 are fixedly connected with a locking cylinder 506, and the outer surface of the rotating cylinder 505 is provided with a movable groove 507 corresponding to the locking cylinder 506. The interior of the movable groove 507 is movably connected with a movable column 508, and the bottom end of the movable column 508 is fixedly connected with a friction plate 509, and the friction plate 509 rests on the outer surface of the locking cylinder 506.

[0049] By moving the moving column 508 downward, the friction plate 509 at the bottom of the moving column 508 is brought into contact with the corresponding locking cylinder 506. At this time, the friction plate 509 and the locking cylinder 506 in contact with each other have a large friction force between the contact surfaces, so that when the rotating cylinder 505 rotates, the moving column 508 is driven to rotate through the moving groove 507, and the moving column 508 drives the corresponding linkage rod 502 to rotate through the friction plate 509 and the locking cylinder 506; when the two laser head bodies 302 process the front and rear sides of the workpiece and the two laser beams are about to meet, one of the moving columns 508 can be moved, so that the moving column 508 drives the corresponding friction plate 509 to move upward, and at this time, the friction plate 509 and the corresponding locking cylinder 506 are no longer in contact, and then the rotating cylinder 505 is rotated, so that the rotating cylinder 505 can drive the friction plate 509 to contact the linkage rod of the locking cylinder 506 502 rotates, at this time, one of the two linkage rods 502 rotates and the other does not rotate, so that the rotating linkage rod 502 drives the corresponding laser head body 302 to move to the next processing point for early processing, and the laser head body 302 corresponding to the non-rotating linkage rod 502 continues to process the workpiece and modify the hole wall. After the hole wall modification action is completed, the two moving columns 508 are moved up and down again, so that the linkage rod 502 rotates and the other linkage rod 502 does not rotate, and then the rotating cylinder 505 is driven, so that the rotating linkage rod 502 drives the corresponding laser head body 302 to move to a processing point and processes the position together with the laser head body 302 that moved to the point earlier, and then the above working process is repeated repeatedly. The above working method avoids the situation where two laser beams irradiate towards each other and cause damage to the optical lens of the internal system of the laser processing cylinder.

[0050] Furthermore, for the above-mentioned rotating cylinder 505, the outer surface of the rotating cylinder 505 is fixedly connected with a guide frame 510, and the guide frame 510 is movably connected inside with a moving frame 511, and the moving frame 511 is sleeved on the outer side of the moving column 508, and the front of the moving column 508 is provided with a guide groove 512, and the guide groove 512 is movably connected inside with a guide rod 513, and the guide rod 513 is fixedly connected to the moving frame 511, and one side of the moving frame 511 is fixedly connected with a moving ring 514, and the moving ring 514 is movably connected to the rotating cylinder 505, and the inner wall of the mounting box 501 is fixedly installed with an electric push rod 515, and limit plates 516 are arranged on both sides of the moving ring 514, and the two limit plates 516 are fixedly connected to the output end of the electric push rod 515.

[0051] The guide groove 512 is composed of a groove perpendicular to the axis of the rotating cylinder 505 and a groove at a certain angle to the groove, and the two grooves are connected to each other; when the two guide rods 513 are both in the grooves horizontally arranged on the corresponding guide grooves 512, the friction plates 509 at the bottom of the two moving columns 508 are in contact with the corresponding locking cylinders 506, so that when the rotating cylinder 505 rotates, the two linkage rods 502 can rotate synchronously. When one of the linkage rods 502 is driven alone, the electric push rod 515 is directly driven, thereby The electric push rod 515 pushes the moving ring 514 to move to the side of the linkage rod 502 that needs to be rotated through the limit plate 516, so that the moving ring 514 pushes the moving frame 511, and the moving frame 511 drives the two guide rods 513 to move inside the corresponding guide grooves 512. At this time, the guide rod 513 corresponding to the linkage rod 502 that needs to be rotated moves in the groove horizontally arranged inside the corresponding guide groove 512, so that the friction plate 509 at this position is always in contact with the locking cylinder 506 The guide rod 513 corresponding to the linkage rod 502 that does not need to rotate moves in the groove inclined inside the corresponding guide groove 512, so that the guide rod 513 pulls the moving column 508 upward through the inclined groove, so that the friction plate 509 at this position is separated from the corresponding locking cylinder 506. The above arrangement makes it only necessary for the electric push rod 515 to push the moving frame 511 to move to the linkage rod 502 that needs to rotate when driving one of the linkage rods 502 alone. That is it, the operation is relatively convenient; at the same time, the setting of the guide frame 510 ensures the stability of the moving frame 511 when it moves; when the rotating cylinder 505 rotates, it can drive the moving frame 511 and the moving ring 514 to rotate together, and at this time the moving ring 514 rotates between the two limit plates 516. This setting makes it possible for the electric push rod 515 to normally adjust the position of the moving frame 511 through the two limit plates 516 and the moving ring 514 no matter how the rotating cylinder 505 drives the moving frame 511 to rotate.

[0052] Furthermore, for the above-mentioned power assembly 6, the power assembly 6 includes a driving motor 601, and the driving motor 601 is fixedly installed at the bottom of the inner wall of the installation box 501. The output end of the driving motor 601 is fixedly connected with a driving gear 602, and the outer surface of the driving gear 602 is meshed with a driven gear 603, and the driven gear 603 is fixedly connected to the rotating cylinder 505.

[0053] By driving the driving motor 601 , the driving motor 601 drives the driving gear 602 to rotate, and the rotating driving gear 602 drives the rotating cylinder 505 to rotate through the driven gear 603 , so that the rotating cylinder 505 drives the linkage rod 502 to rotate.

[0054] Furthermore, for the above-mentioned fixing component 7, the fixing component 7 includes a bidirectional screw 701, the bidirectional screw 701 is rotatably connected to the support frame 1, the outer surface of the bidirectional screw 701 is meshed with an adsorption plate 702, a fixed motor 703 is fixedly installed on the outer side of the support frame 1, the output end of the fixed motor 703 is fixedly connected to the bidirectional screw 701, the front side of the adsorption plate 702 is provided with an adsorption hole 704, and the back side of the adsorption plate 702 is fixedly connected with a transport pipe 705.

[0055] The transport pipe 705 is connected to an external air source. When the workpiece is being processed, the fixed motor 703 is directly driven, so that the fixed motor 703 drives the two adsorption plates 702 to move to the middle or both sides of the support frame 1 at the same time. When the two adsorption plates 702 are moved to the appropriate positions, the workpiece is placed on the two adsorption plates 702. At this time, the air source adsorbs and fixes the workpiece on the adsorption plate 702 through the transport pipe 705 and the adsorption hole 704. The setting of the two adsorption plates 702 that can be adjusted in position in the above setting enables the device to complete the fixation of workpieces of different sizes, and is highly practical.

[0056] Through the above technical solution, 1. The two laser components 3 can be adjusted synchronously on the front and back sides of the workpiece through the longitudinal moving component 2, the power component 6, the linkage component 5 and the transverse driving component 4, so that the two laser components 3 can process the same position of the workpiece from both sides at the same time. Through the bidirectional processing of the laser component 3, the efficiency of cutting the workpiece is doubled. At the same time, because the laser component 3 processes from both sides, the width of the upper and lower slits can be kept consistent, so that the taper and slope of the slit formed during processing are doubled. 2. The driving motor 601 drives the driving gear 602 and the driven gear 603 to rotate, so that the rotating cylinder 505 drives the two linkage rods 502 to rotate under the drive of the driven gear 603, and the two linkage rods 502 drive the horizontal driving screw 402 to rotate through the meshing bevel gears, so that the two laser head bodies 302 can move longitudinally synchronously. This setting makes it possible for the two horizontal screws 402 to move without two driving sources, thereby avoiding the reaction time difference caused by the controller controlling the two driving sources. This causes deviation when the two transverse screws 402 drive the corresponding laser head body 302 to move to the processing position, and affects the processing effect; 3. By pushing the electric push rod 515, the electric push rod 515 pushes the moving ring 514 and the moving frame 511 through the limit plate 516, so that the two guide rods 513 move inside the corresponding guide grooves 512 and make one set of friction plates 509 continue to contact with the locking cylinder 506, and the other set of friction plates and the locking cylinder 506 are separated, so that the rotating cylinder 50 5 is rotated, one linkage rod 502 rotates while the other linkage rod 502 does not rotate. This arrangement enables one of the laser head bodies 302 to move to the next processing point for early processing when the two laser head bodies 302 are processing the workpiece and the two laser beams are about to come into contact with each other, while the other laser head body 302 continues to process at the same position, thereby avoiding the situation where the two laser beams irradiate each other and cause the optical lens of the internal system of the laser processing tube to be damaged. The entire process only requires driving the electric push rod 515.

[0057] A laser drilling and cutting method based on a double-sided laser drilling and cutting device with controllable verticality.

[0058] Step 1: When the two laser head bodies 302 process the same position of the workpiece and the two laser beams are about to meet, the electric push rod 515 is directly driven, so that the electric push rod 515 pushes the moving ring 514 through the two limit plates 516, and the moving ring 514 pushes the moving frame 511 to move inside the guide frame 510;

[0059] Step 2: The moving frame 511 drives the two guide rods 513 to move inside the corresponding guide grooves 512, so that one of the guide rods 513 drives the corresponding moving column 508 to move upward through the guide groove 512 and separates the friction plate 509 from the locking cylinder 506, and the other guide groove 512 only guides the corresponding guide rod 513 in the horizontal direction, so that the friction plate 509 at this position continues to contact with the locking cylinder 506;

[0060] Step 3: Drive the driving motor 601, so that the driving motor 601 drives the rotating cylinder 505 to rotate through the driving gear 602 and the driven gear 603. At this time, the rotating cylinder 505 drives one of the linkage rods 502 to rotate. The rotating linkage rod 502 drives the corresponding transverse screw 402 to rotate through the driving bevel gear 503 and the driven bevel gear 504, so that the transverse screw 402 drives the corresponding laser head body 302 to move to the next processing position for early processing;

[0061] Step 4: After the laser head body 302 that has not moved has pierced through the previous processing position, step 2 is repeated in reverse, and then step 3 is repeated again, so that the laser head body 302 is also moved to the next processing position, so that the two laser head bodies 302 cooperate again to process the same position of the workpiece.

[0062] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
