Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a laser cutting equipment for synchronously removing leftover material from both sides of a plate. Background Technology

[0002] Laser cutting machines utilize high-temperature laser beams to replace traditional mechanical blades for cutting workpieces. They offer advantages such as high precision, rapid cutting, smooth kerfs, and low processing costs, and are gradually improving upon or replacing traditional metal cutting equipment. The laser cutting head of a laser cutting machine uses an internal optical path system to focus the laser emitted from the laser into a high-power-density laser beam. This high-power-density laser beam irradiates the material being cut, quickly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves relative to the material, the holes continuously form a narrow kerf, completing the cutting process.

[0003] However, traditional laser cutting machines typically place the workpiece directly on a cutting support plane. After processing a single piece, it needs to be replaced before cutting can begin again. This additional time between cutting cycles prolongs the processing time, hindering efficient batch processing. Furthermore, a dust removal and resting period is required before replacement to ensure auxiliary modules effectively remove dust from the cutting chamber, preventing dust and fumes from spreading and polluting the environment and harming operators' health. This further lengthens the processing cycle, resulting in longer overall processing time and lower efficiency for batch processing. In addition, existing laser cutting machines usually only have a single cutting head. When there is scrap material on both sides of the workpiece, it is often necessary to perform cutting along the same path at different points to remove the scrap, further extending the processing cycle. Utility Model Content

[0004] The purpose of this utility model is to provide a laser cutting device that can improve the efficiency of batch processing by defining multiple different workstations to enable the replacement and cutting operations of plates to be carried out simultaneously at different positions, and can improve the cutting speed of a single plate by using a dual-position synchronous cutting method to simultaneously remove the leftover material from both sides of the plate. This solves the problems of traditional laser cutting machine tools requiring independent placement, cutting and replacement operations of plates, resulting in long total processing time and low processing efficiency during batch processing, and existing cutting machine tools usually only have a single cutting head, which requires sequential cutting of the symmetrical leftover material on both sides of the plate, resulting in a long total processing time and further extending the processing cycle.

Several clamping seats capable of limiting the position of the plates are arranged at intervals on the conveyor belt of the conveying assembly. An isolation chamber shell capable of defining the cutting chamber is also supported on the raised mounting base plate. A three-dimensional adjustment assembly capable of changing the working position of the laser cutting head is provided on the inner top surface of the isolation chamber shell. The moving end of the three-dimensional adjustment assembly is provided with a bidirectional translation adjustment assembly capable of adjusting the distance between the two laser cutting heads and an air blowing assembly capable of moving synchronously with the laser cutting head.

[0006] According to a preferred embodiment, the three-dimensional adjustment component includes a lifting mechanism, a transverse translation guide rail, and a longitudinal translation guide rail. The lifting mechanism is detachably mounted on the inner top surface of the isolation chamber shell, and two transverse translation guide rails are arranged in parallel at the lower axial end of the lifting mechanism. The moving ends of the two transverse translation guide rails are respectively connected to the two ends of the rail body of the longitudinal translation guide rail.

[0009] According to a preferred embodiment, the air guide chamber shell of the air blowing assembly is detachably installed at the bottom of the mounting frame, and a strip-shaped flat nozzle is obliquely inserted on the bottom surface of the air guide chamber shell. The side of the air guide chamber shell is also connected to a booster fan installed on the outer wall of the isolation chamber shell via an air supply pipe.

[0010] According to a preferred embodiment, the main shell of the isolation chamber is supported on the raised mounting base by corner support columns, and a dust suction port is also inserted into the side of the main shell parallel to the conveyor belt. The dust suction port is connected to the dust suction module through an exhaust gas delivery pipe.

[0011] According to a preferred embodiment, through openings are provided on both sides of the main housing for the conveyor belt to pass through, and a strip exhaust pipe is provided at the top of the through opening to output surface airflow downward to form an air curtain. The strip exhaust pipe is connected to the column axial flow fan through a flat-mouthed air guide pipe that penetrates the main housing.

[0012] According to a preferred embodiment, two coplanar suspended support strips are also provided at intervals on the side shell wall of the main shell where the dust collection port is embedded, and a bearing plate is movably provided on the two suspended support strips.

[0013] According to a preferred embodiment, the seat of the clamping seat is mounted on the conveyor belt by support blocks, and movable support vertical plates are provided on both sides of the seat.

Furthermore, the bidirectional translation adjustment components allow two laser cutting heads to simultaneously complete equivalent cutting, shortening the dual-zone cutting time for a single workpiece, increasing processing speed, and further reducing the processing cycle. The air-blowing components also provide unilateral protection against flying debris generated during cutting, effectively preventing debris from adhering to the workpiece surface.

Obviously, the following description of the structure of the drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] The technical solutions provided by this utility model will be described in detail below with reference to the accompanying drawings and through embodiments. It should be noted that the descriptions of these embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation thereof. In some examples, because some implementation methods belong to existing or conventional technology, they are not described or are not described in detail. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

[0023] The following is a detailed explanation with reference to the accompanying drawings.

[0024] Example 1

[0025] This application provides a laser cutting device for simultaneous removal of scrap material from both sides of a sheet metal, which includes a raised mounting base plate 1, a conveying assembly 2, a clamping seat 3, an isolation chamber shell 4, a laser cutting head 5, a three-dimensional positioning assembly 6, a bidirectional translation adjustment assembly 7, and an air blowing assembly 8.

[0026] according to Figure 1-3 In one specific embodiment, a conveying assembly 2 capable of intermittently directionally moving the workpiece is provided on a raised mounting base 1. Several clamping seats 3 are spaced apart on the conveyor belt 21 of the conveying assembly 2 to limit the position of the workpiece and ensure its stability during movement. An isolation chamber shell 4 defining a cutting chamber is also supported on the raised mounting base 1. The conveying plane defined by the conveyor belt 21 penetrates the isolation chamber shell 4, intermittently moving the clamping seats 3 and the workpiece directionally into and out of the isolation chamber shell 4, thereby allowing the workpiece to complete the cutting process in an isolated chamber separated from the outside world, preventing cutting debris and dust from spreading to the external environment and causing pollution and harm to the health of operators. A three-dimensional adjustment assembly 6 capable of changing the working position of the laser cutting head 5 is provided on the inner top surface of the isolation chamber shell 4. The moving end of the three-dimensional adjustment assembly 6 is provided with a bidirectional translation adjustment assembly 7 capable of adjusting the distance between the two laser cutting heads 5 so that the two laser cutting heads 5 can synchronously complete equivalent cutting processes, and an air blowing assembly 8 capable of moving synchronously with the laser cutting head 5. The conveying component 2, clamping seat 3, and isolation chamber shell 4 configured in this application can cooperate with each other and are divided into multiple zones, allowing the placement, cutting, and removal of the workpiece to be completed simultaneously at different workstations. This enables three independent processes to be carried out in the same time period. Compared with the single-station mode of traditional cutting machine tools, this can shorten the total processing time and improve the overall processing efficiency when performing batch cutting of workpieces. The isolation chamber shell 4 can also define a cutting chamber that is isolated from the outside world and facilitates the continuous movement of workpieces in and out. The dust collection structure is used to clean the cutting chamber, thereby improving the environmental friendliness of the processing and preventing dust from affecting the cutting accuracy, thus improving the safety and quality of the processing. In addition, this application uses a bidirectional translation adjustment component 7 to enable two laser cutting heads 5 to complete equivalent cutting processes simultaneously, shortening the dual-zone cutting processing time of a single workpiece, increasing the processing speed and further shortening the processing cycle. Furthermore, the air blowing component 8 can block the splashing debris generated during the cutting process on one side, effectively preventing debris from splashing and adhering to the surface of the workpiece.

[0027] Preferably, the conveyor belt 21 of the conveyor assembly 2 is mounted on two conveyor rollers of equal height located on both sides of the isolation chamber shell 4. Preferably, the two ends of the shaft of the conveyor roller are rotatably connected to the support column, so that the support column supported on the raised mounting base plate 1 can effectively position the suspended position of the conveyor roller. Preferably, a stepper drive motor connected to the conveyor roller is also provided on the support column to drive the conveyor belt 21 to perform intermittent stepping movement in an adjustable manner. Preferably, the stepper drive motor forms a circuit with the power supply and controller through a cable, so that the operator can make the stepper drive motor rotate intermittently according to the needs by setting parameters and programming the motion program in advance, thereby driving the conveyor belt 21 to perform intermittent stepping movement. The stepper conveyor belt structure is existing technology and will not be described in detail here. When the manufacturing personnel perform assembly production, they can simply rotate a conveyor belt of appropriate specifications and adjust the unit translation amount and movement interval by setting parameters to adapt to the conveying requirements of the plate. For example, the conveyor assembly 2 can be selected from the ZKLw500As series of high-precision conveyor belt equipment with adjustable working parameters.

[0028] Preferably, the seat 31 of the clamping seat 3 is mounted on the conveyor belt 21 via support blocks 32. Preferably, movable support vertical plates 33 are also provided on both sides of the seat 31. Specifically, the support blocks 32 are connected to the seat 31 to position the intermittent arrangement of multiple seats 31, and the movable support vertical plates 33 are aligned on both sides of the support blocks 32. Thus, the support blocks 32 and the movable support vertical plates 33 cooperate with each other on the support plane formed by the conveyor belt 21 to support and position the seat 31 in a flat state and ensure its stability, preventing the seat 31 from shaking. By setting the movable support plates 33 at the same height as the support blocks 32, the support stability and the connection stability when the conveyor belt 21 rotates and deforms are improved, avoiding the defect that multi-point, wide-range connections cannot follow the direction of the conveyor belt 21. Preferably, inverted U-shaped clamping plates 34 are movably fastened to the two aligned top edge protrusions 311 of the seat 31. More preferably, an adjusting screw 35, capable of rotatably connecting with the top edge protrusion 311, is threaded into the side of the inverted U-shaped clamp 34. Specifically, the base 31 and the support block 32 are fixedly connected by integral forming or welding, and the support block 32 is fixedly connected to the conveyor belt 21 by rivets or other structures inserted into the conveyor belt 21. Preferably, an anti-slip pad layer is provided on the side of the inverted U-shaped clamp 34 near the plate to ensure the stability of the contact limiting. When processing a batch of plates with different sizes, the operator manually screws the adjustment screw 35 beforehand to adjust the width of the slot structure formed by the clamping seat 3. This allows for effective clamping of plates of different sizes, enabling the adjusted clamping seat 3 to repeatedly and easily clamp and transfer multiple plates from the same batch, thus facilitating continuous processing. The multiple clamping seats 3 arranged at equal intervals can separate the feeding, cutting, and picking operations, allowing different operations to be performed simultaneously at different positions on the conveyor belt 21. This ensures that the cutting and picking operations are not performed at the same point, thereby improving the efficiency of batch processing.

[0029] Preferably, the main shell 41 of the isolation chamber shell 4 is supported on the raised mounting base plate 1 by corner support columns 42. Preferably, a dust suction port 43 is also inserted into the side of the main shell 41 parallel to the conveyor belt 21. More preferably, the height of the dust suction port 43 is lower than the height of the suspended working plane defined by the conveyor belt 21, so that the blowing airflow and dust fumes after contacting the plate can flow in a direction under the negative pressure of the dust suction port 43 and enter the dust suction port 43, avoiding dust and cleaning airflow from being stirred up or debris from being scattered everywhere, realizing the directional discharge of dust and debris, avoiding dust from spreading in the cutting chamber and affecting the cutting effect, and preventing dust from spreading outward and polluting the environment. Preferably, the dust suction port 43 is connected to the dust suction module 45, which can generate negative pressure traction airflow and can filter the exhaust gas, through the exhaust gas delivery pipe 44. Preferably, the dust collection module 45 can be directly selected from existing industrial dust collection and filtration products, such as the HSJH-D type pulse cartridge dust collector and the RB-MCJC series cartridge dust collector, which are suitable for metal cutting and welding fume control, and are especially suitable for high dust concentration environments. Among them, the RB-MCJC series cartridge dust collector can automatically pulse clean and intelligently control the differential pressure sensor, and can also support the linkage start and stop of the laser cutting machine, thereby improving work efficiency and avoiding the defects of idling or lagging operation.

[0030] Preferably, an auxiliary support plate is longitudinally installed in the cavity of the main housing 41 to provide auxiliary support for the conveyor belt 21 and ensure the flatness and stability of the conveying plane constructed by the conveyor belt 21. Preferably, through openings 411 for the conveyor belt 21 to pass through are provided on both sides of the main housing 41, and a strip exhaust pipe 412 is provided at the top of the through opening 411 to output a downward surface airflow to form a barrier air curtain. Preferably, the strip exhaust pipe 412 is connected to the column axial flow fan 414 through a flat-mouthed air guide pipe 413 that penetrates the main housing 41. Specifically, the column axial flow fan 414 can be a ZKLW3600S type air curtain axial flow fan that can output an airflow with a long strip cross section. Preferably, the bottom surface of the exhaust pipe 412 is provided with a strip-shaped through exhaust port, thereby directing the wide airflow output by the horizontally placed columnar axial flow fan 414 to form a vertical air curtain, which prevents the smoke and dust inside the main housing 41 from leaking out, and improves the isolation and leak prevention capabilities of the cutting process.

[0031] Preferably, the bottom of the main housing 41 is also provided with a door, which facilitates the periodic manual cleaning and transfer of the accumulated cutting scrap in its cavity.

More preferably, a bearing plate 416 is movably provided on the two suspended support bars 415 to limit the structure of the bearing plate 416 and the conveyor belt 21 to be flush and with a cutting gap between them, thereby avoiding deformation and bending of the scrap at the end of the cutting, which would affect the cutting accuracy and effect. Specifically, the bearing plate 416 can be longitudinally translated to ensure the effectiveness of bearing the scrap. Specifically, a sleeve fitted onto the suspended support bar 415 is welded to the bottom surface of the bearing plate 416, and a locking screw is inserted into the side wall of the sleeve, thereby limiting the position of the bearing plate 416 on the suspended support bar 415. Preferably, the support strip 416 has an arc-shaped vertical plate 417, which allows adjustment of the width of the plate outside the conveyor belt 21 on both sides to adjust its placement position, thereby ensuring that the plate is centered on the clamping seat 3 to ensure the precision and accuracy of simultaneous cutting on both sides. Specifically, when the next plate moves close to the support strip 416, it can push the separated corner scraps, causing the corner scraps to fall off and collect at the bottom of the main housing 41.

[0032] Preferably, the laser cutting head 5 is positioned such that its cable end penetrates the mounting plate of the mounting frame 75, allowing its flange structure to abut against the mounting plate. This connection between the laser cutting head 5 and the mounting frame 75 is achieved through bolts, countersunk screws, or similar structures. Preferably, the cable end of the laser cutting head 5 is connected to a laser located outside the isolation chamber shell 4 via an optical fiber cable, thereby shaping and focusing the laser beam to achieve laser-based cutting.

[0033] Preferably, the three-dimensional positioning component 6 includes a lifting mechanism 61, a transverse translation guide rail 62, and a longitudinal translation guide rail 63. Preferably, the lifting mechanism 61 is detachably mounted on the inner top surface of the isolation chamber shell 4. Preferably, two transverse translation guide rails 62 are arranged in parallel at the lower axial end of the lifting mechanism 61. More preferably, the moving ends of the two transverse translation guide rails 62 are respectively connected to the two ends of the rail body of the longitudinal translation guide rail 63, so that the two transverse translation guide rails 62 can drive the longitudinal translation guide rail 63 to translate laterally through synchronous translation. Preferably, the moving end of the longitudinal translation guide rail 63 is connected to a bidirectional translation adjustment component 7. Preferably, the top plate 611 of the lifting mechanism 61 is detachably connected to the inner shell wall of the isolation chamber shell 4 by bolt connection. More preferably, multiple hydraulic lifting rods 612 are provided on the lower surface of the top plate 611. Preferably, the lower axial ends of the hydraulic lifting rods 612 are all connected to the suspended plate 613, so that the top plate 611 and the suspended plate 613 are parallel to each other, and the two transverse translation guides 62 are installed in parallel on the suspended plate 613. Specifically, the two ends of the hydraulic lifting rods 612 are connected to the top plate 611 and the suspended plate 613 by flanges welded to the ends of the rods and countersunk screws inserted into the flanges. Specifically, the rails of the transverse translation guides 62 are connected to the suspended plate 613 by corner bolts. Specifically, the rails of the longitudinal translation guides 63 are also installed and connected by multiple symmetrically arranged corner bolts. Preferably, the transverse translation guides 62 and the longitudinal translation guides 63 are guide rail slide mechanisms with translation plate bodies that facilitate the installation of linkage structures on the moving ends. They can be ZP150-50-500H type high-precision electric translation displacement adjustment slides that can adjust linear motion according to pre-programmed control commands.

[0034] Preferably, the bidirectional translation adjustment assembly 7 includes a guide groove 71 mounted on the moving end of the longitudinal translation guide rail 63, a bidirectional threaded screw 72 rotatably inserted into the guide groove 71, a translation plate base 73 threaded onto the bidirectional threaded screw 72 and whose movement direction is defined by the guide groove 71, and a servo drive motor 74 mounted on the outer end of the guide groove 71 and drivenly connected to the bidirectional threaded screw 72. Preferably, the servo drive motor 74 is capable of individually adjusting the distance between the two laser cutting heads 5 according to instructions and cutting path requirements, or cooperating with the three-dimensional positioning assembly 6 to move the two laser cutting heads 5 along two parallel or symmetrical cutting paths, thereby cutting identical or symmetrical edge contours on both sides of the plate. Preferably, the servo drive motor 74 can be a ZKLW2900M type high-precision servo rotary motor capable of defining a minimum unit quantity of 1-5 rad. Preferably, the translation plate base 73 is also provided with a mounting frame 75.

Specifically, the directional pressurized airflow generated by the booster fan 84 can be output at an angle through the strip-shaped flat nozzle 82, thereby forming a planar air curtain that can prevent molten debris from splashing and spreading to the surface of the plate. This ensures that the splashed debris can only fall on the edge scrap side, and at the same time, the airflow blowing on the surface of the plate can promote the cooling and solidification of the cutting edge area.
