Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and more specifically to a robotic integrated laser cutting station developed based on an integrated die-cast part. Background Technology

[0002] Laser cutting machines are an important component of laser cutting stations. They use high-power-density laser beams to irradiate the material being cut, quickly heating it to its vaporization temperature and causing it to evaporate and form holes. As the beam moves across the material, the holes continuously form narrow kerfs, completing the cutting of the material.

[0003] Referring to the existing Chinese patent document with publication number CN112809200A entitled "A Multi-Station Fully Automatic Laser Cutting Machine", a multi-station fully automatic laser cutting machine is provided, which includes a sliding support and multiple laser cutting devices. It achieves automated production through a feeding mechanism and a waste recycling mechanism. It is equipped with multiple sliding frames and a drive mechanism to realize the flexible movement and multi-directional processing of the laser cutting devices.

[0004] However, during long-term operation, the cutting head of the laser cutting device is constantly exposed to high temperatures, which can easily cause material fatigue and reduce the service life of the cutting head. Summary of the Invention

[0005] This invention provides a robotic integrated laser cutting station based on an integrated die-casting component. Its cutting head has the characteristic of low heat generation, which enables the cutting head to have a longer service life and better cutting quality.

[0006] The present invention provides a robotic integrated laser cutting station based on an integrated die-casting component, which adopts the following technical solution: A robotic integrated laser cutting station based on an integrated die-cast component includes a working chamber, a laser cutting machine, and a cooling jacket. The working chamber contains a work position for holding the material to be cut and a robotic arm capable of changing the output position. The laser cutting machine is mounted on the robotic arm and includes a laser generator and a cutting head. The laser generator emits a laser beam, and the cutting head is located at the bottom of the laser generator. The cutting head receives the laser beam emitted by the laser generator and cuts the material to be cut. The cooling jacket is fitted over the outside of the cutting head, and an annular blind groove is formed around the cutting head inside the cooling jacket. The annular blind groove has a liquid inlet and a liquid outlet. The liquid inlet is connected to a coolant source through a pipe, and the liquid outlet leads to the outside of the working chamber through a pipe.

[0007] Furthermore, an air guide sleeve is provided on the outer side of the cooling jacket, and an air inlet is provided on the top of the air guide sleeve. The air inlet is connected to an external air source through a pipe. A spiral guide plate is provided between the air guide sleeve and the cooling sleeve. The spiral guide plate forms a spiral cavity between the air guide sleeve and the cooling sleeve, and the bottom opening of the spiral cavity leads to the outside of the cooling sleeve.

[0008] Furthermore, the bottom opening of the spiral cavity is an annular opening coaxially arranged with the cutting head, and a guide plate is provided inside the annular opening. The guide plate is configured to guide the air passing through the spiral cavity out of the annular opening in a direction parallel to the laser emitted from the cutting head.

[0009] Furthermore, the air guide plate is provided in multiple pieces, and the multiple air guide plates are evenly distributed around the bottom annular opening of the spiral cavity.

[0010] Furthermore, the spiral guide plate is a hollow plate, with one end of the spiral guide plate connected to an external liquid source via a pipe, and the other end connected to the outside of the cooling jacket via a pipe; Ventilation holes are provided on the cooling jacket at positions corresponding to the spiral guide plate. The side of the spiral guide plate fixed to the cooling jacket is the ventilation surface, which is configured to allow air to pass through while isolating liquid.

[0011] Furthermore, the breathable side is an expanded polytetrafluoroethylene membrane.

[0012] Furthermore, multiple vent holes are provided on the cooling sleeve, and the multiple vent holes are evenly arranged on the cooling sleeve along the length direction of the spiral guide plate.

[0013] Furthermore, the spiral guide plate includes an upper spiral plate and a lower spiral plate, with the upper spiral plate located above the lower spiral plate, and the pitch of the upper spiral plate being smaller than the pitch of the lower spiral plate.

[0014] Furthermore, the spiral guide plate has a quadrilateral cross-section, and the bottom edge of the quadrilateral, away from the cooling sleeve, is skewed toward the side closer to the cutting head outlet.

[0015] Furthermore, a waste conveyor is provided in the working chamber, which is located below the working position and is used to collect the debris generated when the cutting head cuts the material.

[0016] The beneficial effects of this invention are: The present invention discloses a robotic integrated laser cutting station based on an integrated die-casting component. While the laser cutting head is cutting the material, a coolant source is introduced into the annular blind groove through a pipe. The coolant can cool the heated cutting head, which can greatly reduce the possibility of deformation and cracking of the cutting head due to excessive heat generation, greatly improve the service life of the cutting head, and improve the stability of the present invention when cutting materials.

[0017] Furthermore, introducing cold air into the air guide sleeve through the air inlet can also improve the cooling efficiency of the cutting head. After absorbing the heat transferred from the cutting head, the coolant in the cooling sleeve can transfer the heat to the air guide sleeve. The cold airflow inside the air guide sleeve can accelerate the transfer of the heat transferred to the outside of the air guide sleeve. The spiral guide plate allows the cold air to flow in a spiral manner, making the cold air flow more uniform between the air guide sleeve and the cooling sleeve, avoiding uneven distribution of cold air flow, and improving the cooling and heat dissipation efficiency of the cold air flow to the air guide sleeve. In addition, when coolant is introduced into the cooling jacket, there may be uneven flow of coolant within the cooling jacket, which may lead to uneven cooling of the cutting head circumferentially. The spiral flow of cold air can compensate for the uneven flow of water cooling within the cooling jacket in the circumferential direction, and can play a timely role in heat conduction, so that the coolant cools the cutting head more effectively.

[0018] Furthermore, the air guide plate is configured to guide the air passing through the partition cavity out of the annular opening in a direction parallel to the laser emitted from the cutting head. This reduces the possibility of turbulence between the cutting head and the material, and better reduces the probability of high-temperature debris generated by cutting the material entering or adhering to the cutting head. This is more conducive to ensuring the integrity of the cutting head and improving its service life.

[0019] Furthermore, when an external liquid source introduces a high-speed liquid flow into the spiral guide plate through the inlet pipe, according to Bernoulli's principle, the high-speed liquid flow can attract any air bubbles that may exist in the cooling jacket to pass through the vent surface and enter the spiral guide plate, thus preventing air bubbles from blocking the coolant from the side wall of the cutting head and reducing the cooling efficiency of the coolant on the cutting head.

[0020] Furthermore, the pitch of the upper spiral plate is denser than that of the lower spiral plate, so that when the cold air flows through the lower spiral plate, it can flow in a direction closer to the direction from which the laser beam is emitted. This means that the distribution of the air guide plates at the bottom opening of the spiral cavity does not need to be too dense, thus avoiding obstruction of the flow of cold air due to the distribution of the air guide plates being too dense, thereby reducing the cooling efficiency of the present invention. Meanwhile, the vent holes on the side wall of the cooling jacket corresponding to the upper spiral plate are also more densely distributed, which makes it easier for air bubbles in the coolant to be discharged from the densely distributed vent holes when the coolant is introduced into the cooling jacket. This allows the air bubbles in the coolant introduced into the cooling jacket to be discharged in a timely manner, minimizing the impact of the air bubbles on the coolant subsequently introduced into the cooling jacket.

[0021] Furthermore, by setting the bottom edge of the spiral guide plate cross-section to be inclined towards the side closer to the cutting head outlet, impurities in the liquid can accumulate at the bottom of the spiral guide plate away from the cooling sleeve due to centrifugal force and gravity when flowing with the liquid. This can reduce the impact of impurities on the air permeable surface of the spiral guide plate and help maintain the air permeability of the air permeable surface of the spiral guide plate.

[0028] like Figures 1 to 11 As shown in the figure, an integrated robotic laser cutting station based on an integrated die-casting component provided by this invention includes a working chamber 100, a laser cutting machine 200, and a cooling jacket 300. The working chamber 100 is a metal chamber with a door 110 at one end. Working positions 120 are provided on both sides of the door 110, symmetrically arranged about the door 110. The door 110 is rotatable within the working chamber 100, and its rotation changes the positions of the two working positions 120.

[0029] The work chamber 100 is equipped with a robotic arm 130 capable of changing its output position. A laser cutting machine 200 is mounted on the output end of the robotic arm 130. The laser cutting machine 200 includes a laser generator 210 and a cutting head 220; the laser generator 210 is used to emit a laser beam. It should be noted that the robotic arm 130 and the laser generator 210 are existing technologies and will not be described in detail here.

[0030] The cutting head 220 is located at the bottom of the laser generator 210 and is used to receive the laser beam emitted by the laser generator 210. By adjusting the robot arm 130, the cutting head 220 of the laser cutting machine 200 can be controlled to face the material to be cut on the working position 120. The laser beam can pass through the cutting head 220 and fall on the material to be cut. When the robot arm 130 moves the laser cutting machine 200, the laser beam passing through the cutting head 220 can cut the material, thereby realizing the cutting of the material by the present invention.

[0031] The cooling jacket 300 can be a copper jacket. The cooling jacket 300 is fitted onto the outside of the cutting head 220 and is fixedly connected to the outer wall of the cutting head 220. An annular blind groove 310 is formed around the cutting head 220 on the inner side of the cooling jacket 300. The annular blind groove 310 has a liquid inlet hole 321 and a liquid outlet hole 322. The liquid inlet hole 321 and the liquid outlet hole 322 are respectively located near the upper and lower ends of the cooling jacket 300. The liquid inlet hole 321 is connected to a coolant source through a pipe, and the liquid outlet hole 322 leads to the outside of the working chamber 100 through a pipe.

[0032] In this invention, the coolant source can be located in a cooling pool outside the working chamber 100. The cooling pool stores coolant and is equipped with a pump. The pump is connected to the inlet port 321 on the cooling jacket 300 via a pipe, and can introduce coolant into the annular blind groove 310. The pipe connected to the outlet port 322 leads to the outside of the working chamber 100, where heat exchange can be performed through an existing external heat exchange device. The cooled coolant after heat exchange can then be piped back into the cooling pool to reduce coolant waste.

[0033] In addition, in this invention, a waste conveyor 140 is also provided in the working chamber 100. The waste conveyor 140 is located below the working position 120 in the working chamber 100. It can collect the debris generated when the cutting head 220 cuts the material and convey the debris out of the working chamber 100, which helps to keep the working chamber 100 clean and tidy.

[0034] The operating principle of this invention is as follows: First, the material to be cut is fixed on the working position 120. The door 110 is adjusted so that the working position 120 containing the material is located inside the working chamber 100. Then, the robotic arm 130 is controlled to move the laser cutting machine 200 so that the cutting head 220 of the laser cutting machine 200 faces the material to be cut and is at a suitable distance from the material to be cut. Then, the laser cutting machine 200 is started. The laser beam emitted by the laser generator 210 inside the laser cutting machine 200 passes through the cutting head 220 and is directed at the material to be cut. Then, the robotic arm 130 is controlled to move. When the robotic arm 130 moves, it drives the cutting head 220 to move. When the cutting head 220 moves, it can cut the material, thus achieving the cutting of the material. While the cutting head 220 is cutting the material, the coolant source is introduced into the annular blind groove 310 through the pipe. The coolant can cool down the heated cutting head 220, which can greatly reduce the possibility of deformation or cracking of the cutting head 220 due to excessive heat generation, greatly improve the service life of the cutting head 220, and improve the stability of the invention when cutting materials.

[0035] Furthermore, an air guide sleeve 400 is fitted around the outer side of the cooling jacket 300. An air inlet 410 is located at the top of the air guide sleeve 400, and the air inlet 410 is connected to an external air source via a pipe. The air guide sleeve 400 can be a copper sleeve that matches the cooling jacket 300. The air guide sleeve 400 covers the outer wall of the cooling jacket 300, forming a spaced cavity between the air guide sleeve 400 and the outer wall of the cooling jacket 300. The external air source connected to the air guide sleeve 400 via a pipe can provide cool air to the air guide sleeve 400.

[0036] A spiral guide plate 500 is provided between the air guide sleeve 400 and the cooling sleeve 300. The spiral guide plate 500 can be a ceramic spiral plate with poor thermal conductivity. The spiral guide plate 500 makes the cavity between the air guide sleeve 400 and the cooling sleeve 300 form a spiral cavity 420, and the bottom opening of the spiral cavity 420 directly leads to the outside of the cooling sleeve 300.

[0037] In this embodiment, when the cutting head 220 is cutting the material, in addition to the coolant in the cooling jacket 300 cooling the cutting head 220, the air introduced into the air guide sleeve 400 also cools the cutting head 220. After absorbing the heat transferred from the cutting head 220, the coolant in the cooling jacket 300 can transfer the heat to the air guide sleeve 400. The cold airflow flowing in the air guide sleeve 400 can accelerate the transfer of the heat transferred to the outside. The spiral guide plate 500 enables the cold airflow to flow in a spiral state, making the cold airflow more uniform between the air guide sleeve 400 and the cooling jacket 300, avoiding uneven distribution of cold air flow, and improving the cooling and dissipation efficiency of the cold airflow on the heat transferred to the air guide sleeve 400.

[0038] Furthermore, when coolant is introduced into the cooling jacket 300, the lack of a guiding structure to restrict coolant flow may lead to uneven coolant flow within the jacket. This uneven water cooling flow can result in uneven cooling of the cutting head 220 circumferentially. In this embodiment, the spiral-flowing cold air can promptly compensate for the uneven water cooling flow within the cooling jacket 300, effectively conducting heat and improving the cooling effect on the cutting head 220.

[0039] Furthermore, the bottom opening of the spiral cavity 420 is an annular opening coaxially arranged with the cutting head 220. A guide plate 421 is provided inside the annular opening. The guide plate 421 is configured to guide the air passing through the spacer cavity out of the annular opening in a direction parallel to the laser emitted from the cutting head 220.

[0040] Specifically, multiple air guide plates 421 are provided inside the annular opening, and the multiple air guide plates 421 are evenly distributed along the circumference of the annular opening.

[0041] In this embodiment, the spacing between adjacent air guide plates 421 can be relatively close to ensure that the flow direction of the air blown out from the spiral cavity 420 is parallel to the direction of the laser emitted from the cutting head 220.

[0042] When the airflow direction from the spiral cavity 420 is parallel to the direction of the laser emitted from the cutting head 220, the possibility of turbulence between the cutting head 220 and the material can be reduced. This can better reduce the probability of high-temperature debris generated by cutting the material entering the cutting head 220 or adhering to the cutting head 220, which is more conducive to ensuring the integrity of the cutting head 220 and improving its service life.

[0043] In some embodiments, the spiral guide plate 500 is a hollow plate, one end of the spiral guide plate 500 is connected to an external liquid source through a pipe, and the other end is connected to the outside of the cooling jacket 300 through a pipe. A vent hole 430 is provided on the cooling jacket 300 at a position corresponding to the spiral guide plate 500. One side of the spiral guide plate 500 fixed on the cooling jacket 300 is a vent surface 501, which is configured to allow air to pass through and isolate liquid.

[0044] Specifically, the spiral guide plate 500 can be connected to an inlet pipe 510 and an outlet pipe 520 at its two ends, respectively. The external liquid source can be a room temperature liquid source or the aforementioned coolant source. The spiral guide plate 500 is connected to the external liquid source through the inlet pipe 510 and leads to the outside of the cooling jacket 300 through the outlet pipe 520. The external liquid source can introduce a high-speed liquid flow into the spiral guide plate 500.

[0045] Multiple vent holes 430 are provided on the cooling jacket 300, and the multiple cooling jackets 300 are evenly distributed on the outer side wall of the cooling jacket 300 along the length direction of the spiral guide plate 500. The side of the spiral guide plate 500 fixed to the cooling jacket 300 is the vent surface 501, which can be an expanded polytetrafluoroethylene (ePTFE) membrane. The ePTFE membrane has the characteristics of being breathable but impermeable to water.

[0046] When the liquid pump introduces coolant into the cooling jacket 300, it is unavoidable that some air bubbles will be introduced into the coolant. These air bubbles may not only prevent the coolant from directly contacting the side wall of the cutting head 220, but may also form air resistance within the cooling jacket 300, thereby causing poor coolant flow and reducing the cooling efficiency of the cutting head 220.

[0047] When an external liquid source introduces a high-speed liquid flow into the spiral guide plate 500 through the water inlet pipe, that is, when the high-speed liquid flow passes through the expanded polytetrafluoroethylene membrane at the vent hole 430, according to Bernoulli's principle, the high-speed liquid flow can attract any air bubbles that may exist in the cooling jacket 300 to pass through the vent surface 501 and enter the spiral guide plate 500, and finally be discharged from the cooling jacket 300 with the high-speed liquid flow, thereby improving the cooling efficiency of the coolant in the cooling jacket 300 on the cutting head 220.

[0048] Furthermore, the spiral guide plate 500 includes an upper spiral plate and a lower spiral plate, with the upper spiral plate located above the lower spiral plate, and the pitch of the upper spiral plate being smaller than the pitch of the lower spiral plate.

[0049] The smaller pitch of the upper spiral plate compared to the lower spiral plate makes the upper half of the spiral guide plate 500 more densely packed, while the lower half is more sparsely packed. This allows the cool airflow to flow in a direction closer to the laser beam emission direction when passing the lower spiral plate, resulting in a smaller deviation of the cool airflow direction from the laser beam when passing the bottom opening of the spiral cavity 420. Consequently, the distribution of the air guide plates 421 at the bottom opening of the spiral cavity 420 does not need to be too dense, avoiding obstruction of the cool airflow due to an overly dense distribution of the air guide plates 421, thus preventing a reduction in the cooling efficiency of the invention.

[0050] Furthermore, the pitch of the upper spiral plate is denser, which makes the distribution of the vent holes 430 on the side wall of the cooling jacket 300 corresponding to the upper spiral plate more dense. This allows air bubbles in the coolant to be more easily discharged from the densely distributed vent holes 430 when coolant is introduced into the cooling jacket 300, minimizing the impact of air bubbles on the coolant subsequently introduced into the cooling jacket 300.

[0051] Furthermore, the spiral guide plate 500 has a quadrilateral cross-section, and the bottom edge of the quadrilateral, away from the cooling jacket 300, is skewed toward the side closer to the outlet of the cutting head 220.

[0052] The liquid introduced into the spiral guide plate 500 may contain impurities such as scale. These impurities may adhere to the venting surface 501 of the spiral guide plate 500, which is not conducive to the normal passage of air bubbles through the venting surface 501. This may cause a large number of air bubbles to accumulate in the venting hole 430, thereby affecting the cooling efficiency of the coolant in the cooling jacket 300 on the cutting head 220.

[0053] In this embodiment, the bottom edge of the spiral guide plate 500 is set so that the end away from the cooling sleeve 300 is tilted towards the side closer to the outlet of the cutting head 220. This allows impurities in the liquid to accumulate at the bottom of the spiral guide plate 500 away from the cooling sleeve 300 due to centrifugal force and gravity as the liquid flows. This reduces the impact of impurities on the air permeable surface 501 of the spiral guide plate 500 and helps maintain the air permeability of the air permeable surface 501 of the spiral guide plate 500.

[0054] Furthermore, the cross-section of the spiral guide plate 500 can be trapezoidal, wherein the side of the spiral guide plate 500 fixed on the cooling jacket 300 is the small end face, the side fixed on the air guide jacket 400 is the large end face, and the lower inclined surface of the spiral guide plate 500 is inclined toward the side closer to the outlet of the cutting head 220.

[0055] When water flows into the spiral guide plate 500, scale and other impurities in the water flow can accumulate as much as possible in the spiral guide plate 500 near the large end face under the action of centrifugal force and gravity. Since the space on the large end face side is larger, it can accommodate more impurities and reduce the impact of impurities on the water flow.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
