Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting device for large-size cultivated diamond materials. Background Art

[0002] Cultivated diamond is also called artificial diamond. Metal tungsten and cobalt are the main materials for making artificial diamond. The metal tungsten-cobalt alloy synthesized by metal tungsten and cobalt under high temperature and high pressure is called diamond synthesis catalyst, which is used to catalyze graphite to form diamond crystals under high temperature and high pressure. Metal tungsten needs to be decomposed into larger monomer materials before use. Due to the high hardness of metal tungsten, laser cutting has the advantages of high precision, high efficiency and contactless cutting, which can be used as a good cutting method.

[0003] Sometimes, in order to cut multiple materials at the same time, it is necessary to place multiple jigs loaded with materials on the laser cutting path. Compared with small-sized materials, large-sized materials require relatively more cutting times. There is a situation where the small-sized material is cut but the large-sized material is not cut, and then the laser beam directly acts on the jig through the slit, causing the jig to be damaged. In response to the above problems, there are better solutions in the prior art. For example, in the invention patent with the publication number CN116100169B and the name of a diamond laser cutting machine, the jig after cutting is flipped to avoid laser damage to the jig, thereby protecting the service life of the jig. Although the prior art can protect the jig, it still has the following defects. First, there will be space left for the position of the flipped jig, and the laser beam will have empty cutting when passing through. Since the cutting path of the laser head is always reciprocating, the time required for the entire cutting process cannot be shortened, which reduces the cutting efficiency; second, the laser beam will pass through the space and directly act on the inner wall of the casing, which will cause damage to the casing in the long run.

[0004] To this end, a laser cutting device for large-sized cultivated diamond materials is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a laser cutting device for large-sized cultivated diamond materials, which solves the problem of empty cutting after the jig is ejected during the cutting process, thereby reducing the cutting efficiency. On the one hand, after the material inside one of the jigs is cut, the jig can be controlled to automatically eject, and the remaining uncut jigs can be squeezed into a state of sequential adhesion under the action of the clamping assembly, so as to avoid the empty cutting of the laser beam, that is, to achieve the protection of the inner wall of the casing; on the other hand, after the number of jigs is reduced and squeezed into a state of adhesion, the cutting range of the laser transmitter can be shortened, thereby improving the cutting efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A laser cutting device for large-size cultivated diamond materials, comprising a housing, a laser transmitter, a mounting seat, two magnetic blocks and a plurality of jigs, and also comprising a U-shaped card plate, an adsorption component, a camera module, a rebound component, a slide plate, a clamping component and a driving component, wherein the laser transmitter is fixedly arranged on the top of the mounting seat, the mounting seat is arranged inside the housing, the two magnetic blocks are respectively fixedly arranged on the mounting seat and the side wall of the U-shaped card plate, the adsorption component is arranged inside the housing for adsorbing the jig, the camera module is arranged inside the housing, and the adsorption component is controlled to release after monitoring that the material cutting is completed. In addition to the adsorption state, the corresponding jig is ejected through the rebound component. The slide plate is fixedly arranged inside the casing and movably connected to the U-shaped pallet. The clamping component is arranged on the U-shaped pallet, and is used to press multiple jigs that have not completed cutting to a fitting state. The driving component is arranged inside the casing, and is used to drive the laser emitter to move, and after one of the jigs is ejected, the U-shaped pallet and the clamping component are driven downward through the mounting seat, and the downward movement distance of the clamping component is limited according to the number of the jigs. An ultrasonic rangefinder is fixedly arranged on the top of the U-shaped pallet, which is used to adjust the cutting range of the laser emitter.

[0008] By adopting the above scheme, the jig can be ejected after the relatively small material clamped inside one of the jigs is cut, and the remaining jigs can be squeezed into a state of sequential adhesion under the action of the clamping component, so as to avoid gaps between two adjacent jigs as much as possible, effectively avoiding empty cutting while protecting the casing, and being able to use an ultrasonic rangefinder to control the driving direction of the driving mechanism, so as to achieve the effect of gradually reducing the laser cutting range, thereby effectively shortening the cutting time and improving the cutting efficiency. At the same time, the power supply of the laser transmitter can be automatically disconnected after all the materials are cut, so as to avoid the laser transmitter being in working state all the time and penetrating the casing.

[0009] Preferably, the adsorption assembly includes a fixed plate, which is fixedly arranged inside the casing and fixedly connected to a support plate on the right side, a plurality of electromagnets are fixedly arranged on the right side of the fixed plate, an iron block matching the corresponding electromagnet is fixedly arranged at the bottom of each of the jigs, a rotating rod is rotatably arranged at the bottom of each of the iron blocks, and the rod wall of each of the rotating rods is fixedly sleeved with an I-shaped wheel that is slidably engaged with the side of the fixed plate.

[0010] By adopting the above scheme, the magnetizing property of the electromagnet when it is energized can be utilized to adsorb the corresponding iron block, and the contact between the iron block and the electromagnet can be avoided under the action of the I-shaped wheel, thereby reducing the friction between the electromagnet and the iron block during the movement of the fixture, so that the remaining fixtures can be quickly fitted. At the same time, the height position of the fixture can also be limited, so that there is always only one cutting seam on the surface of each material during the laser cutting process.

[0011] Preferably, the magnetic block is arranged on the left side of the laser transmitter, the electromagnet is a closed electromagnet, a spray pipe is arranged on the casing, a spray head is arranged on the side wall of the spray pipe, and the number of the spray heads is the same as the number of the electromagnets.

[0012] By adopting the above scheme, in the process of cutting large-sized diamond materials, coolant is sprayed around each electromagnet and the corresponding large-sized diamond material through the spray pipe and the nozzle, which can reduce the heat-affected zone and prevent material deformation or damage. At the same time, the electromagnet can be cooled to avoid demagnetization of the electromagnet due to high temperature during laser cutting. At the same time, the coolant can be used to buffer the jig to avoid the jig directly colliding with the bottom inner wall of the casing after it is separated from the support plate. The cut material can also be cooled to avoid scalding of the staff when disassembling the material.

[0013] Preferably, the rebound component includes an elastic telescopic rod 1, four of which are provided and fixedly arranged on the left side of the corresponding fixture, and a ball is rotatably arranged on the left end of each of the elastic telescopic rods 1, and each of the balls is rollingly connected to the side wall of the fixed plate, and the four elastic telescopic rods 1 are arranged parallel to the plane where the support plate is located, and the axial direction of the elastic telescopic rod 1 is arranged perpendicular to the axial direction of the rotating rod.

[0014] By adopting the above scheme, the iron block can maintain a vertical state after being adsorbed by the corresponding electromagnet, avoiding the oblique squeezing of the upper and lower surfaces of the I-shaped wheel and the fixed plate, which affects the slowing down of the movement speed of the fixture, thereby avoiding the situation where the remaining fixture has not been fitted during the return movement of the laser transmitter. The action of the ball can reduce the friction between the end of the elastic telescopic rod and the fixed plate, avoiding the friction between the end of the elastic telescopic rod and the fixed plate affecting the pressure block to push the fixture to move.

[0015] Preferably, the iron block is a pentagon and is hollow, the left side of the iron block is set as a plane parallel to the fixed plate, and the top view of the iron block is an isosceles triangle.

[0016] By adopting the above scheme, the hollow iron block can minimize the sinking speed of the jig in the coolant, and can reduce the resistance of the coolant encountered by the jig when it moves horizontally after being ejected, thereby avoiding the jig that is ejected first from blocking the ejection path of the jig that is ejected later.

[0017] Preferably, the clamping assembly includes a rotating shaft, an annular plate and a torsion spring, the rotating shaft is fixedly arranged on the top of the U-shaped clamping plate and is rotatably sleeved with the annular plate, the torsion spring is movably sleeved on the rod wall of the rotating shaft, and the two ends are respectively fixedly connected to the rotating shaft and the annular plate, the side wall of the annular plate is fixedly connected with an elastic telescopic rod 2, the free end of the elastic telescopic rod 2 is arranged in an "L" shape and is rotatably connected with a pressure block, and the pressure block is pressed on the side wall of the corresponding fixture.

[0018] By adopting the above scheme, after the camera module detects that the material cutting inside the fixture is completed, the corresponding electromagnet can be controlled to be powered off and demagnetized for a short time through the external controller. During the short-term demagnetization of the electromagnet, the four elastic telescopic rods 1 can be reset under the action of their own elastic force and drive the corresponding fixture to pop open, which can completely leave space for the remaining fixture to fit again under the squeezing of the torsion spring and the elastic force of the elastic telescopic rod 2.

[0019] Preferably, the inner movable sleeve of the pressing block is provided with a guide rod, and the guide rod is fixedly arranged on the side wall of the fixed plate, and the surfaces of the pressing block and each fixture are mirror-polished.

[0020] By adopting the above scheme, the horizontal movement of the pressing block can be limited under the action of the guide rod, thereby preventing the friction between the pressing block and the jig from affecting the normal ejection of the jig. Mirror polishing of the side walls of the pressing block and the jig can greatly reduce the friction encountered during the ejection process of the jig, allowing it to eject quickly and avoid the laser beam passing through the jig again after cutting.

[0021] Preferably, a plurality of slots are provided on the surface of the skateboard, and a limiting assembly is provided on the top of the U-shaped card plate, the limiting assembly comprises a hollow column, a damping sleeve and a wedge-shaped rod, the hollow column is fixedly sleeved inside the damping sleeve, the damping sleeve is fixedly embedded in the inside of the U-shaped card plate, a through hole one is provided at the bottom of the hollow column, the wedge-shaped rod is movably penetrated inside the through hole one, a through hole two is provided at the bottom of the U-shaped card plate, the wedge-shaped rod passes through the through hole two and matches with the corresponding slot, the wedge-shaped rod comprises an upper section and a lower section, the radial cross-sections of the upper section and the through hole one are both set to be rectangular, a steering assembly is provided on the hollow column, which drives the wedge-shaped rod to rotate after all materials are cut.

[0022] By adopting the above scheme, the rotational connection between the hollow column and the U-shaped clamping plate can be realized under the action of the damping sleeve. At the same time, the situation that the hollow column rotates due to shaking during the cutting process can be avoided. The role of the wedge-shaped insertion rod can realize the one-way limit of the U-shaped clamping plate, avoiding the situation that the U-shaped clamping plate actively moves away from the laser emitter under the reaction force of the elastic force of the torsion spring and the elastic telescopic rod II. After the material cutting in the last jig is completed, the wedge-shaped insertion rod can be flipped 180° under the action of the steering component, thereby ensuring the reset of the pressing component and facilitating the subsequent normal use of the entire cutting device.

[0023] Preferably, the driving component includes a motor, a reciprocating lead screw and an internally threaded tube. The motor is fixedly arranged on the outer wall of the machine shell. The reciprocating lead screw is rotatably arranged inside the machine shell and fixedly connected to the output end of the motor. The internally threaded tube is threadedly sleeved on the rod wall of the reciprocating lead screw and fixedly connected to the mounting seat. A receiver matching the ultrasonic rangefinder is arranged on the top of the mounting seat. The mounting seat is movably sleeved with the sliding plate. The mounting seat is a copper seat and two water pushing grooves are symmetrically arranged on the side wall.

[0024] By adopting the above scheme, under the action of the water pushing grooves, the contact area between the mounting seat and the coolant can be increased, so that the mounting seat can expand the pushing range of the coolant during the moving process. At the same time, the good heat conduction effect of copper can be used to introduce the internal temperature of the machine shell into the coolant for cooling, reducing the influence of the high temperature generated during the cutting process on the entire cutting device.

[0025] Preferably, the steering component includes a gear ring fixedly sleeved with the hollow column. A rack is meshed on one side of the gear ring. A strip-shaped opening is formed inside the rack. A fixed block is fixedly arranged on the top of the U-shaped clamping plate. The rack is movably sleeved with the fixed block through the strip-shaped opening. A pressure switch is fixedly arranged at the end of the rack. The pressure switch is matched with the laser emitter.

[0026] By adopting the above scheme, after one cutting is completed, the mutual attraction between the two magnetic blocks can enable the mounting seat to continue driving the U-shaped clamping plate to move downward during the downward movement. At this time, the wedge-shaped insertion rod moves out of the inner part of the lowest slot. The lower end of the rack is blocked and automatically pushes the wedge-shaped insertion rod to rotate 180°, so that the process of the mounting seat driving the pressing component to reset will not be affected by the limiting component, and the power supply of the laser emitter can be automatically disconnected under the action of the pressure switch. There is no need for the staff to manually cut off the power, and it can also prevent the staff from causing the laser emitter to always be in the working state and penetrate the machine shell due to negligence.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. The existing laser cutting device for large-size cultivated diamond materials cuts the material by driving the laser emitter to move back and forth. In the process of cutting multiple materials, the jig is protected by driving the jig to flip after the cutting is completed. However, there is a gap after the jig is flipped, which causes the laser emitter to have an empty cut during the movement and damage the inner wall of the casing. In order to improve this problem, an adsorption component, a clamping component and a rebound component are used, and an ultrasonic rangefinder is combined. The position of the mounting seat is detected by the ultrasonic rangefinder and the moving direction of the mounting seat is adjusted, so that the position of the jig after being ejected can fill the unfinished cutting jig, thereby avoiding the empty cut state, realizing the simultaneous protection of the jig and the inner wall of the casing, and the cutting range can be gradually shortened during the cutting process, effectively improving the cutting efficiency.

[0029] 2. By setting the torsion spring and the second elastic telescopic rod, after the jig is loaded, the elastic force of the torsion spring and the second elastic telescopic rod can drive the pressure block to automatically press the jig, thereby avoiding the existence of a gap between two adjacent jigs. By connecting the set wedge-shaped plug rod with the corresponding slot, it is possible to avoid driving the U-shaped card plate to move upward under the reaction of the elastic force of the torsion spring and the second elastic telescopic rod, thereby achieving a stable fit between the two adjacent jigs.

[0030] 3. The sliding connection between the I-wheel and the support plate can avoid the friction between the iron block and the electromagnet when the electromagnet is energized to magnetize and adsorb the iron block. At the same time, the rebound component can be set to avoid the I-wheel from tilting, so that the axis of the I-wheel can always remain vertical to the plane of the support plate, thereby reducing the influence of friction during the movement of the pressing block extrusion fixture, ensuring the automatic fitting between the two adjacent fixtures, and achieving the effect of no empty cutting during the movement of the laser transmitter and no damage to the inner wall of the casing.

[0031] 4. By setting up an ultrasonic rangefinder, when the ultrasonic rangefinder detects that the mounting seat moves to the set distance from the ultrasonic rangefinder, the moving direction of the mounting seat can be adjusted through the reciprocating screw rod, and the mounting seat can drive the U-shaped card plate to move downward under the action of two magnetic blocks until the wedge-shaped rod is plugged into the new slot, thereby effectively shortening the cutting range and achieving the effect of improving the cutting efficiency.

[0032] 5. Through the meshing connection between the gear ring and the rack, when the U-shaped pallet moves downward until the rack is blocked by the casing, the gear ring can be driven to rotate by the continued downward movement of the U-shaped pallet. At this time, the wedge-shaped rod has been moved out from the inside of the lowest slot, and then the hollow column can be used to drive the wedge-shaped rod to rotate 180°, avoiding the reciprocating screw rod from being blocked when driving the laser transmitter to move upward after all materials are cut. When the rack moves upward to the upper end and is blocked by the casing, the gear ring can drive the wedge-shaped rod to rotate 180° in the opposite direction, ensuring the normal use of the entire cutting device next time.

[0044] 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.

[0045] See also Figures 1 to 10 The present invention provides a laser cutting device for large-size cultivated diamond materials, and the technical solution is as follows:

[0046] For details, please refer to Figure 1 , Figure 2 and Figure 3A laser cutting device for large-size cultivated diamond materials includes a housing 1, a laser emitter 2, a mounting seat 3, two magnetic blocks 4, and a plurality of jigs 5, and also includes a U-shaped card plate 6, an adsorption component 7, a camera module 8, a rebound component 9, a slide plate 10, a pressing component 11, and a driving component 12. The laser emitter 2 is fixedly arranged on the top of the mounting seat 3, and the mounting seat 3 is arranged inside the housing 1. The two magnetic blocks 4 are respectively fixedly arranged on the side walls of the mounting seat 3 and the U-shaped card plate 6. The adsorption component 7 is arranged inside the housing 1 for adsorbing the jig 5. The adsorption component 7 includes The fixing plate 701 is fixedly arranged inside the housing 1 and is fixedly connected to a support plate 702 on the right side. A plurality of electromagnets 703 are fixedly arranged on the right side of the fixing plate 701. An iron block 704 matching the corresponding electromagnet 703 is fixedly arranged at the bottom of each fixture 5. A rotating rod 705 is rotatably arranged at the bottom of each iron block 704. The rod wall of each rotating rod 705 is fixedly sleeved with an I-shaped wheel 706 that is slidably engaged with the side of the fixing plate 701. The magnetic block 4 is arranged on the left side of the laser emitter 2. The electromagnet 703 is a closed electromagnet. The electromagnet 703 is sealed in a waterproof housing, which is usually made of corrosion-resistant materials (such as stainless steel) and is suitable for wet or underwater environments. A spray pipe 707 is provided on the housing 1, and a nozzle 708 is provided on the side wall of the spray pipe 707. The number of the nozzles 708 is the same as the number of the electromagnets 703. In the process of cutting large-sized diamond materials, the cooling liquid is sprayed to each electromagnet 703 and the surrounding of the corresponding large-sized diamond materials through the spray pipe 707 and the nozzle 708, which can reduce the heat-affected zone and prevent the material from being deformed or damaged. At the same time, the electromagnet 703 can be cut. 03 is cooled to prevent the electromagnet 703 from losing magnetism due to the influence of high temperature during the laser cutting process. At the same time, the coolant can be used to buffer the jig 5 to prevent the jig 5 from directly colliding with the bottom inner wall of the casing 1 after it is separated from the support plate 702. The cut material can also be cooled to prevent the staff from being scalded when disassembling the material. The coolant can be retained in the casing 1, and a filter screen and a circulation pump are set inside the casing 1 to realize the recycling of the coolant. This is a conventional technical solution, so it is not described in detail.

[0047] After the electromagnet 703 is energized, the electromagnet 703 generates magnetic force, thereby being able to adsorb the iron block 704 and prevent the iron block 704 from moving to the right. Under the action of the I-shaped wheel 706 and the support plate 702 being clamped together, the iron block 704 can be restricted to prevent the iron block 704 from directly contacting the electromagnet 703, so that the electromagnet 703 can both adsorb the iron block 704 and avoid a large friction force after the electromagnet 703 contacts the iron block 704. By using the coolant arranged inside the casing 1, the electromagnet 703 and the magnetic block 4 can be cooled during the operation of the laser transmitter 2, so as to prevent the magnetic block 4 and the electromagnet 703 from losing magnetism due to the high temperature generated during the cutting process, thereby effectively ensuring the normal use of the magnetic block 4 and the electromagnet 703.

[0048] As an embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 The camera module 8 is arranged inside the casing 1. After monitoring that the material cutting is completed, the adsorption component 7 is controlled to release the adsorption state and the corresponding fixture 5 is ejected through the rebound component 9. The rebound component 9 includes an elastic telescopic rod 901. Four elastic telescopic rods 901 are provided and are respectively fixed on the left side of the corresponding fixture 5. A ball 902 is rotatably provided on the left end of each elastic telescopic rod 901. Each ball 902 is rollingly connected to the side wall of the fixed plate 701. The four elastic telescopic rods 901 are arranged parallel to the plane where the support plate 702 is located, and the axial direction of the elastic telescopic rod 901 is perpendicular to the axial direction of the rotating rod 705.

[0049] After the material inside one of the jigs 5 is cut, the camera module 8 can send a control signal and disconnect the power supply of the electromagnet 703 corresponding to the jig 5 through the external controller. At this time, the electromagnet 703 loses magnetism, and the four elastic telescopic rods 901 on the side wall of the jig 5 are reset after the electromagnet 703 disconnects the magnetic adsorption of the iron block 704, and the corresponding jig 5 can be completely ejected during the resetting process, thereby preventing the laser beam from passing through the cut of the material and acting on the surface of the jig 5.

[0050] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4 The iron block 704 is a pentagon and is hollow. The left side of the iron block 704 is set as a plane parallel to the fixed plate 701. The top view of the iron block 704 is an isosceles triangle.

[0051] The hollow setting of the iron block 704 can reduce its own gravity, thereby reducing the sinking speed of the jig 5 in the coolant after being ejected, and under its own pentagonal shape setting, it can reduce the resistance it receives when moving in the coolant, so that the jig 5 can be as far away from the fixed plate 701 as possible after being ejected, avoiding the ejected jig 5 from blocking the ejection path of the subsequent jig 5.

[0052] As an embodiment of the present invention, refer to Figure 5 The slide plate 10 is fixedly arranged inside the casing 1 and movably sleeved with the U-shaped card plate 6. The clamping assembly 11 is arranged on the U-shaped card plate 6, and is used to press the multiple unfinished cutting jigs 5 to a fitting state. The clamping assembly 11 includes a rotating shaft 1101, an annular plate 1102 and a torsion spring 1103. The rotating shaft 1101 is fixedly arranged on the top of the U-shaped card plate 6 and rotatably sleeved with the annular plate 1102. The torsion spring 1103 is movably sleeved on the rod wall of the rotating shaft 1101, and the two ends are respectively fixedly connected to the rotating shaft 1101 and the annular plate 1102. The side wall of the annular plate 1102 is fixedly connected with an elastic telescopic rod 1104. The free end of the elastic telescopic rod 1104 is set in an "L" shape and is rotatably connected with a pressing block 1105. The pressing block 1105 is pressed on the side wall of the corresponding jig 5.

[0053] After one of the above-mentioned jigs 5 is ejected, the torsion spring 1103 drives the annular plate 1102 to rotate the elastic telescopic rod 1104 through its own elastic force. During the rotation of the elastic telescopic rod 1104, the free end extends from the inside of the fixed end and drives the pressing block 1105 to squeeze the corresponding jig 5, so that the remaining uncut jigs 5 are tightly fitted in turn, thereby avoiding the laser emitter 2 from being in an empty cutting state during the movement.

[0054] As an embodiment of the present invention, refer to Figure 5 The inner movable sleeve of the pressing block 1105 is provided with a guide rod 1106, and the guide rod 1106 is fixedly arranged on the side wall of the fixed plate 701. The surfaces of the pressing block 1105 and each fixture 5 are mirror-polished.

[0055] By using a mirror polishing process for the side walls of the pressing block 1105 and each jig 5, the friction between the pressing block 1105 and the jig 5 and the two adjacent jigs 5 can be ignored, so that the jig 5 can be quickly ejected after the electromagnet 703 is powered off and demagnetized, and the adjacent jigs 5 will not be affected during the ejection process.

[0056] As an embodiment of the present invention, refer to Figure 5 , Figure 6 and Figure 7A plurality of slots 14 are provided on the surface of the skateboard 10, and a limiting assembly 16 is provided on the top of the U-shaped card plate 6. The limiting assembly 16 includes a hollow column 1601, a damping sleeve 1602 and a wedge-shaped rod 1603. The hollow column 1601 is fixedly sleeved inside the damping sleeve 1602, and the damping sleeve 1602 is fixedly embedded inside the U-shaped card plate 6. A through hole 1604 is provided at the bottom of the hollow column 1601, and the wedge-shaped rod 1603 is movably inserted into the through hole 1604. A through hole 2 1605 is provided at the bottom of the U-shaped card plate 6, and the wedge-shaped rod 1603 passes through the through hole 2 1605 and matches with the corresponding slot 14. The wedge-shaped rod 1603 includes an upper section 16031 and a lower section 16032. The radial cross-sections of the upper section 16031 and the through hole 1 1604 are both set to be rectangular.

[0057] Under the action of the wedge-shaped insertion rod 1603 and the multiple slots 14 opened on the surface of the slide plate 10, the moving direction of the U-shaped clamping plate 6 can be limited, so that when the cutting work is not completed, the mounting seat 3 can only drive the U-shaped clamping plate 6 to move in one direction through the adsorption force between the two magnetic blocks 4, thereby realizing the one-way limitation of the rotating shaft 1101, avoiding the reaction of the torsion spring 1103 and the elastic force of the elastic telescopic rod 1104 to drive the U-shaped clamping plate 6 to move upward and affect the clamping effect on the fixture 5.

[0058] As an embodiment of the present invention, refer to Figure 7 and Figure 8 The driving component 12 is arranged inside the casing 1, and is used to drive the laser transmitter 2 to move, and after one of the jigs 5 is ejected, the U-shaped card plate 6 and the clamping component 11 are driven to move downward through the mounting seat 3, and the downward movement distance of the clamping component 11 is limited according to the number of the jigs 5. An ultrasonic rangefinder 13 is fixedly arranged on the top of the U-shaped card plate 6, which is used to adjust the cutting range of the laser transmitter 2. The driving component 12 includes a motor 1201, a reciprocating screw rod 1202 and an internal threaded tube 1203. The motor 1201 is fixedly arranged on the outer wall of the casing 1, the reciprocating screw rod 1202 is rotatably arranged inside the casing 1 and is fixedly connected to the output end of the motor 1201, the internal threaded tube 1203 is threadedly sleeved on the rod wall of the reciprocating screw rod 1202 and is fixedly connected to the mounting seat 3, and a receiver 1204 matching the ultrasonic rangefinder 13 is arranged on the top of the mounting seat 3. The mounting seat 3 is movably sleeved with the slide plate 10, and the mounting seat 3 is a copper seat and two water push grooves 15 are symmetrically opened on the side wall.

[0059] Under the action of the reciprocating screw 1202, the laser transmitter 2 can be driven to reciprocate along the axial direction of the reciprocating screw 1202, and the rotation direction of the reciprocating screw 1202 can be adjusted through the set value between the ultrasonic rangefinder 13 and the receiver 1204, so that the cutting range can be shortened after the number of jigs 5 is reduced, thereby effectively improving the cutting efficiency. Under the action of the water push trough 15, the contact area between the mounting seat 3 and the coolant can be increased, so that the mounting seat 3 can push the coolant to shake during the movement, thereby avoiding the local internal heating of the coolant. At the same time, the copper seat can be used to guide the temperature inside the casing 1 into the coolant, thereby achieving cooling of the interior of the casing 1.

[0060] As an embodiment of the present invention, refer to Figure 6 , Fig. 9 and Fig.10 A steering assembly 17 is provided on the hollow column 1601, and the wedge-shaped rod 1603 is driven to rotate after all materials are cut. The steering assembly 17 includes a gear ring 1701 fixedly sleeved with the hollow column 1601, a rack 1702 is meshed on one side of the gear ring 1701, a strip-shaped opening 1703 is provided inside the rack 1702, a fixed block 1704 is fixedly provided on the top of the U-shaped clamping plate 6, the rack 1702 is movably sleeved with the fixed block 1704 through the strip-shaped opening 1703, and a pressure switch 1705 is fixedly provided at the end of the rack 1702, and the pressure switch 1705 matches the laser emitter 2.

[0061] After all the materials inside the jig 5 are cut and ejected, the mounting base 3 can continue to move downward by attracting the U-shaped card plate 6 through the two magnetic blocks 4, and can drive the pressure switch 1705 to collide with the inner wall of the casing 1 through the rack 1702 to turn off the laser emitter 2. When the rack 1702 is blocked during its downward movement, the wedge-shaped rod 1603 can be driven by the rack 1702 to rotate 180°, thereby avoiding being restricted by the slot 14 when the mounting base 3 drives the U-shaped card plate 6 to move upward. When the upper end of the rack 1702 is blocked by the inner wall of the casing 1, the gear ring 1701 can also be driven to drive the wedge-shaped rod 1603 to flip 180° to ensure the normal operation of the cutting device next time.

[0062] Working principle: Before cutting, a plurality of jigs 5 loaded with materials are placed on the right side of the support plate 702, and the I-shaped wheel 706 is clamped with the support plate 702, and each electromagnet 703 is energized. After being energized, the electromagnet 703 is magnetized and adsorbs the corresponding iron block 704. However, under the obstruction of the corresponding I-shaped wheel 706 and the four elastic telescopic rods 1 901, each iron block 704 does not contact the electromagnet 703. The elastic telescopic rod 2 1104 is rotated to align the pressing block 1105 with the side of the nearest jig 5. The side is fitted, and under the action of the guide rod 1106, the pressing block 1105 can be prevented from moving horizontally, and under the elastic force of the elastic telescopic rod 1104 and the torsion spring 1103, the pressing block 1105 can be driven to squeeze the fixture 5, so that all the fixtures 5 are in a sequentially fitted state. At this time, the upper end of the rack 1702 is in contact with the inner wall of the housing 1, and the fixing block 1704 is located at the uppermost position of the strip opening 1703, so that the U-shaped card plate 6 cannot move, thereby stably pressing multiple fixtures 5;

[0063] During cutting, the camera module 8, the motor 1201 and the ultrasonic rangefinder 13 are started. The motor 1201 drives the internal threaded tube 1203 through the reciprocating screw 1202 to drive the mounting seat 3 and the laser transmitter 2 to move along the cutting path. When the internal threaded tube 1203 moves to the lowest thread of the reciprocating screw 1202, the laser transmitter 2 can be driven to reset through the mounting seat 3. When the mounting seat 3 drives the receiver 1204 to move to the set position of the ultrasonic rangefinder 13, the ultrasonic rangefinder 13 sends a control signal, and uses the external controller to drive the output end of the motor 1201 to drive the reciprocating screw 1202 to rotate in the opposite direction, thereby driving the laser transmitter 2 to change the moving direction.

[0064] After the camera module 8 detects that the material cutting inside one of the jigs 5 is completed, the camera module 8 sends a control signal to control the corresponding electromagnet 703 to be powered off for a short time through the external controller. During the power-off process of the electromagnet 703, the four elastic telescopic rods 1 901 on the side wall of the jig 5 are reset and the jig 5 is ejected. The torsion spring 1103 drives the annular plate 1102 to drive the elastic telescopic rod 2 1104 to rotate through its own elastic force. Under the elastic force of the torsion spring 1103 and the elastic telescopic rod 2 1104, the pressing block 1105 can be driven to squeeze the side wall of the corresponding jig 5, so that the remaining uncut jigs 5 are tightly fitted inside the support plate 702 in turn, so as to avoid empty cutting of the laser transmitter 2 and damage to the inner wall of the housing 1. After the jig 5 is ejected, the electromagnet 703 is powered on again to facilitate the adsorption of the iron block 704 pressed to this position by the pressing block 1105.

[0065] After the remaining fixture 5 is pressed and the mounting seat 3 moves downward, the magnetic force between the two magnetic blocks 4 can be used to adsorb the U-shaped clamping plate 6, so that the mounting seat 3 can drive the U-shaped clamping plate 6 to move during the downward movement, and under the action of the U-shaped clamping plate 6, the wedge-shaped insertion rod 1603 is driven to be inserted and limited with the corresponding slot 14, achieving the effect of adjusting the position of the ultrasonic rangefinder 13, and thus the subsequent cutting range can be shortened;

[0066] After the camera module 8 monitors that all materials have been cut, the camera module 8 sends a control signal to control the ultrasonic rangefinder 13 and all the electromagnets 703 to be powered off. The mounting seat 3 drives the U-shaped clamping plate 6 to move through the adsorption between the two magnetic blocks 4, and drives the pressure switch 1705 at the end of the rack 1702 to be squeezed against the inner wall of the machine shell 1 under the drive of the reciprocating lead screw 1202, realizing the power-off of the laser emitter 2, and can drive the hollow column 1601 to drive the wedge-shaped insertion rod 1603 to rotate 180° by meshing with the gear ring 1701, avoiding the mounting seat 3 being blocked by the wedge-shaped insertion rod 1603 during the upward reset process, so as to ensure the normal use of the entire cutting device next time.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
