Description

All-in-one laser processing device

The present invention relates to an integrated laser processing device capable of removing slag, which can remove and prevent slag generated during laser processing.

The laser cutting machine includes a laser cutting head that can move in a horizontal plane, and plates such as steel sheets to be cut by the laser cutting machine are mounted on a table and supplied into the cutting area of the laser cutting machine so that cutting work can be performed at a defined position.

The table used in this laser cutting machine is equipped with a support plate to support the processing object to be cut. The support plate is used to reduce the area of direct contact with the object to be processed so that the melt residue that is melted as it is cut during laser processing can escape smoothly downward.

Typically, the support plate is a strip-shaped support plate with irregularities or grooves formed on the upper surface, placed vertically at regular intervals in order to reduce the contact area with the object to be processed.

In addition, the laser processing device is provided with a laser head that radiates laser, and the laser head moves from the upper side of the processing object to irradiate the laser to perform cutting processing. At this time, slugs melted by the laser are generated on the cut surface of the object to be processed.

Therefore, various technologies have been proposed in conventional laser processing devices to prevent or remove such slugs.

For example, a conventional slug prevention device uses a technology that discharges auxiliary gas to the laser head so that slugs do not remain on the laser cutting surface and are discharged to the support plate.

In addition, many studies have been conducted recently to prevent slugs from remaining in processing objects, and among them, research has been conducted on the discharge pressure and incidence angle of auxiliary gas. Looking at the research results, it was concluded that the auxiliary gas is incident on the cutting surface from an inclined direction, the higher the discharge pressure, and the narrower the contact area of the auxiliary gas, the less likely slugs on the cutting surface are generated.

However, the existing auxiliary gas is spread externally and is carried out in a way that contacts a larger area with the auxiliary gas, which is significantly different from the above research results.

That is, conventionally, the auxiliary gas nozzle integrated with the laser head that irradiates the laser was installed for the purpose of cooling a larger area, so there is a problem in that slugs cannot be completely removed from the cut surface of the processing object.

In addition, on the support plate, the material is discharged between the cuts of the processing object and flows down to the support plate and is fixed. Therefore, conventionally, a subsequent process is performed to remove the slug fused to the support plate. The most commonly used method at this time is to rotate the roller to remove the slug stuck to the support plate.

However, since this conventional method removes slugs through friction by directly contacting the support plate, both the support plate and the roller may be worn.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a block diagram showing an integrated laser processing device according to the present invention, and Figure 2 is a perspective view showing an integrated laser processing device according to the present invention.

Referring to Figures 1 and 2, the present invention includes a laser processing member 100, a working water supply member 200, a spray nozzle 300, a scraper drive unit 400, a table 600, Includes a frame member 700.

In addition, the present invention provides a control unit 10 that controls the laser processing member 100, the working water supply member 200, the spray nozzle 300, the scraper drive unit 400, and the frame member 700, and the operations of each component. and a sensor unit 20 equipped with a plurality of sensors for detecting the location and surrounding situation.

Here, the control unit 10 may be installed separately for each component or may be installed to output integrated control commands, and may be provided with a memory that stores programs and calculation algorithms for processing objects.

The sensor unit 20 includes a position detection sensor for detecting the position or work status of the laser processing member 100, the injection nozzle 300, the frame member 700, and the scraper driving unit 400, a video camera, and whether or not there is an operation. and at least one of a current and voltage sensor, a flame or smoke detection sensor, a human body detection sensor, a temperature detection sensor, and a humidity detection sensor for detecting the presence or absence of a malfunction or abnormal voltage or current.

The frame member 700 includes a support frame 720 installed to be movable in the forward and backward direction along movable rails installed on both sides of the table 600, and a first rail extending laterally between the support frames 720 on both sides. It includes a support frame 710 and a second rail support frame 720 extending transversely in the front direction of the first rail support frame 710.

Here, the support frame 720 is movable along rails (not referenced) formed on both sides of the table 600, and the first rail support frame 710 and the second rail support frame 720 are laser processing members. (100) and the scraper driving unit 400 are supported so as to be movable in the left and right directions.

The first rail support frame 710 extends from the top of the support frames 720 on both sides, and the second rail support frame 720 extends in a direction intersecting the extension frames extending from each of the support frames 720 on both sides.

Therefore, the first rail support frame 710 and the second rail support frame 720 move simultaneously with the support frame 720, and can movably support the scraper driving unit 400 and the laser processing member 100. .

The laser processing member 100 includes a laser output unit 110 that outputs a laser to process a processing object, and a first rail unit 120 that moves the laser output unit 110 in the horizontal direction.

The laser output unit 110 may include a laser head 111 that radiates laser and a coaxial nozzle 112 that discharges auxiliary gas. The detailed configuration of the laser head 111 and the coaxial nozzle 112 will be described later.

The first rail unit 120 supports the laser output unit 110 so as to move laterally along the first rail support frame 710. That is, the laser output unit 110 can move in the left and right directions by the first rail unit 120. Since this coupling structure between the first rail unit 120, the first rail support frame 710, and the laser output unit 110 applies generally known technology, detailed description thereof will be omitted.

The scraper driving unit 400 is movably supported by the second rail unit 430 along the second rail support frame 720. The scraper driving unit 400 is capable of moving up and down to remove slag remaining on the outer surface of the support plate 610 aligned at the top of the table 600. A detailed explanation will be provided later.

A plurality of spray nozzles 300 are aligned on both sides of the upper surface of the table 600 and discharge working water in the inner direction. For example, a plurality of spray nozzles 300 are aligned on the support panel 301 that stands upright and extends from both sides of the upper surface of the table 600 and sprays working water.

Here, the spray nozzle 300 sprays working water in the form of mist. At this time, the sprayed working water is sprayed on the outer surface of the support plate 610. It is preferable that the discharge of working water is performed before the processing of the laser output unit 110.

The working water supply member 200 supplies working water to the spray nozzle 300. Here, the working water supply member 200 includes a storage tank (not shown) in which working water is mixed and stored, and a working pump (not shown) that discharges the working water stored in the storage tank (not shown) to the spray nozzle 300. ) and a water pipe (not shown) extending from the storage tank (not shown) to the working pump and spray nozzle 300 may be further provided.

Here, the working water is, for example, soapy water so that slag does not remain on the support plate 610 and flows down.

The table 600 is provided with a plurality of support plates 610 arranged on the upper surface. A plurality of support plates 610 are aligned to support the processing object. Here, the support plate 610 according to the present invention is characterized by forming a space so that working water can be accommodated in the support plate 610 for a long time.

In particular, soapy water can slow or prevent the solidification of slag, thereby solving the problem of difficulty in removing the slag because it solidifies after it falls on the support plate 610. This is explained with reference to FIG. 3.

Figure 3 is an enlarged perspective view of the support plate.

Referring to FIG. 3, the support plate 610 has a shape in which a plurality of bodies A and A' protruding upward in an oval shape are connected to each other at the lower side, and the support plate 610 extends in one direction and is aligned on the upper part of the table 600. . Each body (A, A') has a tip 611 protruding at the top, an inward groove 612 extending downward from the tip 611, and a receiving part 613 that collects slugs between the bodies. may include.

Here, the body may be formed in an oval shape with a more expanded area in both directions, and the area may become narrower toward the bottom. Therefore, it is preferable that the spacing (L1) between the end points in the lateral direction of the body is narrower than the spacing (L2) between the receiving portions 613 between the bodies.

The tip portion 611 is formed in the shape of a protrusion that protrudes upward from the top of the body, and is formed in the shape of a square protrusion so that the top forms a flat surface. The upper part, which has such a square protrusion, supports the lower part of the object to be processed and can prevent damage such as scratches to the object to be processed due to friction.

The inward groove 612 is formed to face inward at the side end of the body (A). Here, the inward groove 612 extends in both directions from the tip 611 and extends to the next body (A'). That is, as shown, the inward groove 612 is characterized in that it extends from one side of the support plate 610 to the opposite end.

The receiving portion 613 forms a curved surface between the bodies. Here, the receiving portion 613 refers to the upper part of the connecting portion between the bodies. The receiving portion 613 serves to collect slugs that fall from the inward groove 612 or the top of the body.

For example, the conventional support plate 610 is a triangle in which sawtooth bodies forming downward slopes on both sides of the tip are continuously aligned. Such a conventional support plate 610 is made in such a way that rollers are rotated on both walls to crush slugs through friction. However, although this method is easy to remove slugs remaining on the wall, it requires a longer period of time to completely remove slugs from the sharp tip and the serrated end of the body.

Therefore, the present invention collects and processes slugs that have fallen from the support plate 610 to the tip portion 611 and the ends of the body A and A', which were previously difficult to remove, into the receiving portion 613, which is easier to remove. To do this, an inward groove 612 and a receiving portion 613 are formed, and working water is sprayed.

Here, the slugs are collected from the tip 611 and the end into the receiving part 613 due to the working water.

The receiving portion 613 is an empty space formed because the end between the body (A) and the body (A') forms an inward curved surface, and is an inward groove extending from the tip 611 of both bodies (A, A'). It can accommodate working water and slugs flowing in through (612). At this time, the slug is collected in a state that is not completely fixed in the receiving part 613 due to the working water that collects in the receiving part 613 through the inward groove 612.

That is, in the present invention, the support plate 610 is divided into the body (A) and the body (A') so that the slugs that have fallen to the tip and both sides of the body can be collected into the receiving portion 613 through the inward groove 612 where the working water remains. The gap between them is narrowed, but a receiving portion 613 is formed with a more expanded space at the bottom.

The scraper driving unit will be described in more detail with reference to FIGS. 4 to 6.

FIG. 4 is a perspective view showing the scraper driving unit 400, FIG. 5 is a schematic view showing the first scraper 410, and FIG. 6 is a schematic view showing the second scraper 420.

Referring to FIGS. 4 to 6 , the scraper driving unit 400 includes a first scraper 410 and a second scraper 420.

Here, the first scraper 410 and the second scraper 420 are supported to be movable in the transverse direction by the second rail portion 430 supported by the second rail support frame 720. Therefore, the first scraper 410 and the second scraper 420 can sequentially remove slag as in secondary cutting after primary cutting.

For example, the second scraper 420 crushes the slug with a stronger force, and the first scraper 410 separates the crushed slug from the support plate 610 with a weaker force. .

To be more specific, the first scraper 410 includes a pair of conical rollers 411 spaced apart from each other, a first lifting means 413 for raising and lowering the conical rollers, and the conical roller 411 for rotating. It includes a first rotation means (412).

The conical rollers 411 are a pair spaced apart from each other and may be provided with brushes at the ends and/or opposite surfaces facing each other. The conical roller 411 rotates on both sides with the body in between, and brushes formed on the ends and/or inner walls strike and rub the slug to separate it from the support plate 610.

Preferably, the conical roller 411 may proceed subsequently after the second scraper 420 first crushes the slug.

The first lifting means 413 can raise and lower the rotation shaft that rotatably supports the conical roller 411. Here, the first lifting means 413 may be a device consisting of a rack and pinion combination structure and a motor.

The first rotation means 412 rotates the conical roller 411. Here, the first rotation means 412 rotates the conical roller 411 according to the detection of a sensor (not shown) and the control command of the control unit 10.

The second scraper 420 includes a pair of pressure rollers 421 that press with the body in between, a second rotation means 422 for rotating the pressure rollers 421, and a pressure roller 421. May include a second lifting means 423 for raising and lowering.

The pressure rollers 421 rotate and rise and fall as a pair to pulverize and/or crush the slugs remaining on both walls of the body. For this purpose, the pressure roller 421 is formed to have a spirally extending protrusion or a strip-shaped extended groove shape on its outer surface.

This type of pressure roller 421 is characterized in that it rotates to press both walls of the body and simultaneously moves up and down to hit the slug and separate it from the body. That is, in the present invention, the pressure roller 421 does not crush the slug by friction, but moves up and down while rotating to crush the slug remaining on the wall of the support plate 610.

The second rotation means 422 rotates the pressure roller 421.

The second lifting means 423 raises and lowers the pressure roller 421. At this time, the second lifting means 423 raises and lowers the pressure roller 421 according to the position detection signal from the sensor and/or the control command from the control unit 10. At this time, the second lifting means 423 can lift, wait, and lower the pressure roller 421 at a set time period (for example, 2 seconds of lifting, then 1 second of waiting, 2 seconds of lowering).

The structures of the laser head 111 and the coaxial nozzle 112 will be described with reference to FIGS. 7 to 9.

FIG. 7 is a cross-sectional view showing the laser head 111 of the laser processing member 100, FIG. 8 is a perspective view showing the auxiliary gas coaxial nozzle 112, and FIG. 9 is a plan view.

Referring to FIGS. 7 to 9, the laser output unit 110 includes an output body 113 in an upright shape, a laser head 111 that is fixed to the lower part of the output body 113 and outputs a laser, and a laser head ( 111) may be provided with a coaxial nozzle 112 that is fastened to the outer surface and discharges auxiliary gas.

Here, the laser head 111 has an irradiation hole 111a formed at the center of the laser head 111 to output the laser to the processing object. As the laser head 111 applies generally known technology, its description is omitted.

The coaxial nozzle 112 is fixed on the outer surface of the laser head 111 and discharges the auxiliary gas introduced through the flow path formed inside the output body 113 of the laser head 111 to the target area.

Here, the coaxial nozzle 112 has a narrow shape from the top to the bottom so that the auxiliary gas can be concentrated and discharged into the target area.

Specifically, the coaxial nozzle 112 includes a coaxial cap 112a having an upper and lower narrow shape, a plurality of guide grooves 112c that protrude and extend in a spiral shape from the inner surface of the coaxial cap 112a, and It includes a flow path groove (112b) between the guide grooves (112c) and a gas discharge port (112d).

The coaxial cap 112a has an upper-lower narrow shape whose width decreases from the top to the bottom, and whose upper surface is open and is fixed to the outer surface of the laser head 111. Here, the coaxial cap 112a may be configured to be detachable or integrally fixed to the outer surface of the laser head 111.

A plurality of guide grooves 112c are spaced apart from each other and protrude from the inner surface of the coaxial cap 112a. At this time, the guide groove 112c protrudes from the inner surface of the coaxial cap 112a and extends spirally to the gas discharge port.

The flow path groove 112b is formed as an inward-facing space between the guide grooves 112c and extends spirally to the gas discharge port.

Accordingly, the auxiliary gas has directionality as it is discharged through the guide groove 112c and the flow groove 112b extending spirally from the coaxial nozzle 112. When the directional auxiliary gas is discharged to the target area, it can be concentrated and discharged in a narrower area.

Therefore, the discharge pressure of the auxiliary gas increases, increasing the cooling effect of the target area (T1), and as the wind speed of the auxiliary gas flowing into the cutting surface of the processing object increases, the melt generated during laser processing can be easily removed.

That is, in the past, it was proposed to discharge the auxiliary gas over a larger area, but in the present invention, it is characterized by concentrating it into a narrower area, because the higher the pressure of the auxiliary gas, the higher the slug removal effect.

In addition, the present invention is rotatably fixed on the outer surface of the laser head 111 in addition to the coaxial nozzle 112 as described above, so that the auxiliary gas can be diffused and discharged into the previous processing area and/or the expected processing area, including the target area. It may further include a diffusion gas discharge unit 130. This diffusion gas discharge unit 130 will be described with reference to FIGS. 10 to 13.

FIG. 10 is a diagram showing a laser head equipped with a diffusion gas discharge unit, and FIG. 11 is a diagram showing an operation example of a deaxial nozzle.

Referring to FIG. 10, the diffusion gas discharge unit 130 is supported by a rotating means 131 rotated on the outer surface of the output body 113 of the laser head 111 and the rotating means 131 to discharge auxiliary gas. It may include a discharge housing 132 and a deaxial nozzle 133.

The rotation means 132 is rotatably fixed to the outer surface of the output body 113 of the laser head 111. The rotation means, for example, is a device that is rotatably installed on the outer surface of the upright body of the laser output unit 110 and extends laterally, and the discharge housing 132 is fixed at one end.

That is, the rotation means 131 is rotated in the left and right directions in the body of the laser output unit 110 while being operated according to the control of the control unit 10, the on of the switch, or the detection signal of the sensor.

In addition, the rotation means 131 is preferably rotated so that the gas discharge means 132 is oriented in a direction consistent with the processing area (processing line L) of the laser head 111.

The discharge housing 132 is fixed by the rotation means 131. Therefore, the discharge housing 132 is rotated simultaneously with the rotation means 131. Here, the discharge housing 132 is fastened to the rotating means 131 in an inclined position and supports the de-axial nozzle 133 fixed at the tip to be oriented toward the previous processing area (cutting line).

At this time, the discharge housing 132 is preferably fixed to the rotation means 131 so as to be inclined so as to discharge the auxiliary gas from the target area (T1) where the laser is output to the previous processing area (T2).

Here, the discharge housing 132 may be formed with a flow path (not shown) that delivers auxiliary gas to the deaxial nozzle 133 fixed to the tip.

The auxiliary gas supplied to the deaxial nozzle 133 may be supplied through a supply device separate from the coaxial nozzle 112 of the laser head 111. Alternatively, the deaxial nozzle 133 may receive auxiliary gas from the same supply device as the coaxial nozzle 112.

The deaxial nozzle 133 is fixed to the tip of the discharge housing 132 and discharges the auxiliary gas supplied through the discharge housing 132.

The deaxial nozzle 133 can discharge auxiliary gas to the previous processing area. For example, the coaxial nozzle 112 focuses on the target area currently being processed, and the deaxial nozzle 133 spreads the auxiliary gas to the previously processed area to prevent slugs on the cutting surface.

To this end, the deaxial nozzle 133 may include a deaxial cap (133a) and a rotary blade (133b).

The deaxial cap (133a) has an axis of the rotary blade (133b) and an inlet (133d) through which the auxiliary gas flows in the upper surface, and in the case of an embodiment that concentrates the auxiliary gas, it may have an upper and lower narrow shape as shown in the drawing. In addition, in the drawing, the inlet 133d is given the same symbol as the rotation axis 133d of the rotary blade 133b.

The rotary blades 133b are rotated by the operation of the rotary motor 134 and provide directionality to the auxiliary gas discharged to the inside of the deaxial cap 133a (when the rotary blades 133b are accommodated inside the deaxial cap 133a). Grant.

This is to reduce the auxiliary gas discharged to areas other than the cut surface and allow the auxiliary gas to be discharged between the cut surfaces. Therefore, the rotary blades 133b and the rotary motor can increase the discharge pressure of the de-axial nozzle 133 and provide directionality at the same time.

In addition, as shown in previous studies, the escape nozzle is characterized by discharging auxiliary gas in an inclined direction to the processing area (for example, the cutting line where the cutting surface by the laser head 111 is connected).

In this way, the auxiliary gas incident from the inclined direction is effective in suppressing the peeling flow of the cut surface and preventing slag from remaining.

That is, the present invention can suppress slag remaining on the cut surface processed by a laser by providing discharge pressure and direction to the auxiliary gas, thereby reducing the defect rate.

In addition, in the present invention, in addition to the above-described laser head 111, the first scraper 410 and the second scraper 420 are integrated, and the slag is collected on the support plate 610 to an area where it is easier to remove. In the future, slag discharged to the support plate 610 can be removed and cleaned more easily.

The embodiments of the present invention described above are merely illustrative, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible.

Therefore, it will be understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached patent claims. In addition, the present invention should be understood to include all modifications, equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims.
