Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a laser cutting machine which is advantageous in reducing loss. Background Art

[0002] Laser cutting machine is a device that uses high-energy laser beam to accurately cut materials. It is widely used in important fields such as metal processing industry, electronic and electrical industry, energy and environmental protection due to its high efficiency, high precision and non-contact processing characteristics.

[0003] The laser generators of traditional laser cutting machines on the market are all fixed and independent of the laser head. That is, the laser generator does not move during the cutting process and remains fixed, while the laser head slides along the slide rail. In this way, the laser beam generated by the laser can be emitted to the laser head through a reflector and laser cutting can be performed. However, for laser cutting tables with a long travel distance, the transmission distance of the laser beam is too long, which will cause the laser to lose energy during the transmission process. At the same time, the laser is easily affected by external environmental interference, which affects the cutting quality.

[0004] Moreover, the length of the laser cutting platforms on the market is usually fixed, and the length of the cutting platform cannot change with the length of the material to be cut, and the flexibility is relatively low. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] like Figure 1-13 As shown, the present invention provides a laser cutting machine that is beneficial to reducing losses, including a first cutting platform 1, a second cutting platform 2, an adsorption mechanism 3, a cutting box 4, a laser 5, a reflector assembly 6, a laser head 7, a first driving mechanism 8 and a second driving mechanism 9.

[0035] The second cutting platform 2 is detachably connected to the first cutting platform 1. It should be understood that after the first cutting platform 1 and the second cutting platform 2 are spliced ​​together, the cutting area of ​​the laser cutting platform can be enlarged, thereby enabling the laser cutting platform to accommodate larger areas of objects to be cut (hereinafter collectively referred to as products), and thus meeting more needs.

[0036] The adsorption mechanism 3 is disposed in the first cutting platform 1 and is used to vacuum the first cutting platform and the second cutting platform.

[0037] Preferably, the top surfaces of the first cutting platform 1 and the second cutting platform 2 are both composed of a mesh support plate. It should be understood that after placing a product on the cutting platform, the adsorption mechanism 3 will generate suction to the product on the first cutting platform 1 through the mesh of the first cutting platform 1, thereby firmly adsorbing one end of the product to the top surface of the cutting platform. The adsorption mechanism 3 will also generate suction to the product on the second cutting platform 2 through the mesh of the second cutting platform 2, thereby firmly adsorbing the other end of the product to the top surface of the cutting platform. In this way, the entire product can be adsorbed on the cutting platform, making it easier for the laser head to perform cutting.

[0038] Specifically, the adsorption mechanism 3 includes a vacuum pump 33 , a first adsorption disk 311 and a second adsorption disk 321 .

[0039] The vacuum pump 33 is disposed in the first cutting platform 1 and is used to generate vacuum adsorption.

[0040] The first suction plate 311 is funnel-shaped and is positioned below the bottom surface of the support plate of the first cutting platform 1. The suction port at the bottom of the first suction plate 311 is connected to the first suction port of the vacuum pump 33 via a first tube. It should be understood that the first suction plate 311 can absorb the entire bottom surface of the first cutting platform 1, thereby adsorbing any product on the first cutting platform 1 onto the surface of the cutting platform.

[0041] The second suction plate 321 is funnel-shaped and is positioned below the bottom surface of the support plate of the second cutting platform 2. The suction port at the bottom of the second suction plate 321 is connected to the second suction port of the vacuum pump 33 via a second tube. It should be understood that the second suction plate 321 can absorb the entire bottom surface of the second cutting platform 2, thereby adsorbing any product on the second cutting platform 2 onto the surface of the cutting platform.

[0042] Preferably, the second tube body is composed of a hose, wherein one end of the second tube body is detachably connected to the adsorption port at the bottom end of the second adsorption disk 321 , and the other end of the second tube body is detachably connected to the second adsorption port of the vacuum pump 33 .

[0043] It can be understood that the first adsorption plate 311 and the second adsorption plate 321 share a vacuum pump 33, which can save a suction source. Moreover, since the second adsorption plate 321 is connected to the vacuum pump 33 by a second tube body composed of a hose, it is more convenient to connect the first cutting platform 1 and the second cutting platform 2 when splicing them. After the first cutting platform 1 and the second cutting platform 2 are separated, the second tube body can also be easily removed from the vacuum pump 33 and the second adsorption plate 321 for storage, and will not take up too much space.

[0044] The cutting box 4 is slidably arranged on both sides of the first cutting platform 1 and the second cutting platform 2 , wherein a receiving cavity is provided in the cutting box 4 .

[0045] The laser 5 is used to generate a laser beam, and the laser 5 is arranged in the receiving cavity.

[0046] The reflector assembly 6 is disposed in the receiving cavity and is used to reflect the laser beam emitted by the laser 5 to the laser head 7 .

[0047] The laser head 7 is disposed in the receiving cavity and is used to receive the laser beam reflected by the reflector assembly 6 and cut the product on the first cutting platform 1 or the second cutting platform 2 through the laser beam, wherein the laser head 7 is provided with a brush 71 that can be raised and lowered. It should be understood that by integrating the laser 5, the reflector assembly 6, and the laser head 7 in the cutting box 4, the travel of the laser beam can be greatly shortened, thereby conserving the energy of the laser. At the same time, the laser is protected by the cutting box 4 and is naturally not disturbed by the external environment.

[0048] It can be understood that after the product is placed on the cutting platform, the cutting box 4 can slide along the two side ends of the first cutting platform 1 and the second cutting platform 2, and the laser system inside the cutting box 4 (the laser system refers to the laser 5, the reflector assembly 6 and the laser head 7) will use the laser head 7 to laser cut the product on the cutting platform, and the brush 71 in the laser head 7 can mark the surface of the product.

[0049] The first driving mechanism 8 is arranged in the receiving cavity of the cutting box 4, and is used to drive the laser head 7 to slide along the first direction in the receiving cavity, so as to drive the laser head 7 to cut the objects to be cut on the first cutting platform 1 or the second cutting platform 2 along the width (i.e., the first direction) of the cutting platform.

[0050] The second driving mechanism 9 is disposed in the receiving cavity and is used to drive the cutting box 4 to slide along the second direction on both sides of the first cutting platform 1 and the second cutting platform 2. It is worth noting that the first direction and the second direction in this embodiment are perpendicular to each other.

[0051] It can be understood that the first driving mechanism 8 allows the laser head 7 to perform laser cutting in the first direction, and combined with the second driving mechanism 9, the cutting box 4 can slide in the second direction. Naturally, the laser head 7 can also cut any part of the product on the cutting platform.

It should be understood that there are two first profile supports 11, which are symmetrically arranged on the first cutting platform 1, and there are two third profile supports 21, which are symmetrically arranged on the second cutting platform 2.

[0053] It should be understood that the first profile support 11 is provided with a first connecting member 13, and the third profile support 21 is provided with a second connecting member 23. After the first connecting member 13 and the second connecting member 23 are connected, the first cutting platform 1 and the second cutting platform 2 can be spliced ​​together, and the insert 24 inserted into the slot of the second profile support 12 and the fourth profile support 22 can also connect the top of the first cutting platform 1 and the second cutting platform 2 together. Not only that, the insert 24 connects the two platforms together while maintaining the tops of the two platforms in the same plane, so as to avoid the situation where the cutting is misaligned due to the unevenness of the product. Furthermore, the bottom walls of the first slot 121 and the second slot 221 are both provided with a first positioning screw hole, and the insert 24 is provided with a second positioning screw hole 241 corresponding to the first positioning thread, wherein the second positioning screw hole 241 and the second positioning screw hole are threadedly connected with a positioning screw.

[0054] Preferably, the first profile pillar 11 is provided with a first slot 111 along the vertical direction, and the first connecting member 13 is provided with a socket on the surface, and a pin is also inserted in the socket of the first connecting member 13, and the other end of the pin is detachably connected to the first slot 111, so that the first connecting member 13 and the first profile pillar 11 are detachably connected, and the second profile pillar 21 is provided with a second slot 211 along the vertical direction, and the second connecting member 23 is also provided with a socket on the surface, and a pin which is also detachably connected to the second slot 211 is also inserted in the socket of the second connecting member 23, so that the first connecting member 13 can be detachably installed on the inner side surface of the first profile pillar 11, and the second connecting member 23 can also be detachably installed on the inner side surface of the second profile pillar 21.

[0055] Furthermore, a first protrusion 131 is extended from one side of the first connecting member 13, and a plurality of first threaded holes 132 are provided on the first protrusion 131. A second protrusion 231 is extended from one side of the second connecting member 23, and a plurality of second threaded holes 232 corresponding to the first threaded holes 132 are provided on the second protrusion 231. First bolts are passed through the first threaded holes 132 and the second threaded holes 232, so that the first connecting member 13 and the second connecting member 23 are detachably connected together, so that the first cutting platform 1 and the second cutting platform 2 can also be detachably connected together.

[0056] In this embodiment, rectangular baffles 25 are detachably provided on the outer sides of the first and third profiled support pillars 11, 21. The first and third profiled support pillars 11, 21 are of equal length, and the baffles 25 are of equal vertical length to the first profiled support pillar 11. It should be understood that the baffles 25 can conceal other components within the first and third profiled support pillars 11, 21, thereby closing the gap between the first and second cutting platforms 1, 2, and giving the laser cutting machine a neat overall appearance.

[0057] Furthermore, a first magnet 26 is provided on the outer side of the first profile pillar 11 and the third profile pillar 21, and a second magnet corresponding to the first magnet 26 is provided on the inner side of the baffle 25, so that the baffle 25 can be detachably magnetically attracted to the outer side of the first profile pillar 11 and the third profile pillar 21, making the disassembly and installation of the baffle 25 more convenient.

The laser 5 is in the shape of an elongated rectangle and is arranged on the other side of the bottom wall of the receiving cavity along the first direction. The reflector assembly 6 includes a first reflector 61, a second reflector 62, and a third reflector 63. The first reflector 61 is arranged at one end of the receiving cavity (i.e., one side of one end of the receiving cavity, in a straight line with the laser 5), the second reflector 62 is arranged at the other end of the receiving cavity (i.e., the other side of one end of the receiving cavity, in a straight line with the laser head 7), and the third reflector 63 is arranged on the laser head 7. It should be understood that the laser beam emitted by the laser 5 is reflected by the first reflector 61 onto the second reflector 62, then reflected by the second reflector 62 onto the third reflector 63, and finally, the third reflector 63 transmits the laser beam to the laser head 7, and the laser head 7 cuts the product on the cutting platform.

[0059] Furthermore, a first door 44 is provided on one side of the cutting box 4, which is rotatable via a first hinge, and a second door 45 is provided on the other side of the cutting box 4, which is rotatable via a second hinge.

[0062] The mounting plate 83 includes a vertical plate 831 and a horizontal plate 832. The vertical plate 831 is connected to the first slide 82 and is located within the slotted hole. The laser head 7 is mounted on the vertical plate 831. It should be understood that the vertical plate 831 and the horizontal plate 832 are perpendicularly connected to each other to form the mounting plate 83. The mounting plate 83 can slide along the first slide rail 81 in the first direction, thereby allowing the laser head 7 to perform sliding cutting in the first direction.

[0063] The first driving motor 84 is disposed on the horizontal plate 832 .

[0064] The first rack 85 is disposed on the bottom wall of the receiving cavity along a first direction, wherein the rotating shaft of the first drive motor 84 is provided with a first gear 841 that engages with the first rack 85. In other words, when the first drive motor 84 is started, the first gear 841 engages with the first rack 85 and rotates, and at the same time, the mounting plate 83 slides on the first slide rail 81 via the first slider 82.

[0065] In this embodiment, the second and third slide rails 92 and 93 are provided on both sides of the first cutting platform 1, respectively, and the fourth and fifth slide rails are provided on both sides of the second cutting platform 2, respectively.

The second slider is slidably provided on the second and fourth slide rails 92 and 93, and the third slider 431 is slidably provided on the third and fifth slide rails. It should be understood that when the cutting box 4 slides in the second direction along both sides of the first and second cutting platforms 1 and 2, the second slider will slide on the second and fourth slide rails 92 and 93, and the third slider 431 will slide on the third and fifth slide rails, so that the cutting box 4 can slide.

[0066] In other embodiments, the third cutting platform can be further spliced ​​at the side end of the second cutting platform 2 away from the first cutting platform 1, and so on. The specific adjustment can be made according to the length of the product, which will not be explained in detail here.

[0067] Furthermore, a second rack 15 and a third rack are respectively provided at both side ends of the first cutting platform 1, and a fourth rack and a fifth rack are respectively provided at both side ends of the second cutting platform 2, the second rack 15 and the fourth rack are in the same horizontal plane, and the third rack and the fifth rack are in the same horizontal plane, wherein the second driving mechanism 9 includes a second driving motor 91 and a third driving motor, the second driving motor 91 is arranged in the first extension part 42, the third driving motor is arranged in the second extension part 43, and a second gear 911 that meshes with the second rack 15 or the fourth rack is provided on one side of the first extension part 42 facing the second extension part 43, and a third gear 432 that meshes with the third rack or the fifth rack is provided on one side of the second extension part 43 facing the first extension part 42, and the rotating shaft of the second driving motor 91 is connected to the second gear 911, and the rotating shaft of the third driving motor is connected to the third gear 432.

[0068] That is, when the second drive motor 91 is started, the second gear 911 engages with the second rack 15 or the fourth rack and rotates. When the third drive motor is started, the third gear 432 engages with the third rack or the fifth rack and rotates. The second drive motor 91 and the third drive motor are both arranged at the two side ends of the receiving cavity of the cutting box 4, and the second slider of the first extension 42 is slidably arranged on the second slide rail 92 or the fourth slide rail 93, so that after the second drive mechanism 9 is started, the cutting box 4 can be slid along the second direction on the first cutting platform 1 or the second cutting platform 2, thereby enabling large-scale laser cutting. It should be understood that the second drive motor 91 and the third drive motor are driven and paused synchronously.

[0069] In this embodiment, the cutting box 4 includes a first box and a second box. The first box and the second box are detachably connected. The inner cavity of the first box and the inner cavity of the second box form a receiving cavity. The inner cavity of the first box is provided with a laser head 7 and a second reflector 62, and the inner cavity of the second box is provided with a laser 5 and a first reflector 61. In other words, the first box and the second box can be separated as needed.

[0070] Specifically, a magnet is provided on the outer wall of the second box, and the other end of the first cutting platform 1 is provided with a fixing mechanism that uses magnetic force to attract the magnet of the second box. A trigger mechanism is provided at one end of the first cutting platform 1 and is electrically connected to the fixed structure. A trigger rod is provided at one end of the second cutting platform 2 for issuing the trigger mechanism, wherein when the second cutting platform 2 is connected to the first cutting platform 1, the trigger rod is inserted into the trigger mechanism, and the trigger mechanism controls the fixing mechanism to not generate magnetic force. When the second cutting platform 2 is not connected to the first cutting platform 1, the trigger rod is not inserted into the trigger mechanism, and the trigger mechanism controls the fixing mechanism to generate magnetic force to adsorb the second box, so that the laser 5 is separated from the laser head 7. In other words, when short-stroke laser cutting is required, the laser 5 and the laser head 7 can be separated to expose the device to the outside, which has a better heat dissipation effect (the laser is transmitted in the box, and it is easy to make the box in a high temperature state after working for a long time), that is, the laser 5 does not follow the laser head 7 to move synchronously on the first cutting platform.

[0071] In addition, the first housing and the second housing are also detachably connected via magnetic force, and the magnetic force adsorbed by the first housing and the second housing is smaller than the magnetic force adsorbed by the fixing mechanism and the second housing, so that when the trigger mechanism controls the fixing mechanism to generate magnetic force, the second housing is separated from the first housing and adsorbed in the fixing mechanism. It should be understood that the fixing mechanism may include an electromagnet with a conductive wire wrapped around the outside of the electromagnet. When energized, the electromagnet can generate magnetic force, and when de-energized, the electromagnet does not generate magnetic force. When the trigger rod is not inserted into the trigger mechanism (for example, when the first connecting member 13 and the second connecting member 23 are not connected, the trigger rod is not inserted into the trigger mechanism), the conductive wire is energized.

[0072] It should be understood that the first slide rail 81, the mounting plate 83, the first drive motor 84 and the first rack 85 are all arranged in the inner cavity of the first box, that is, the slotted hole is arranged along the first direction on the bottom wall of the inner cavity of the first box, the first slide rail 81 is arranged along the first direction on the bottom wall of the inner cavity of the first box, the mounting plate 83 is slidably arranged on the first slide rail 81, the first drive motor 84 is arranged on the horizontal plate 832 of the mounting plate 83, the laser head 7 is arranged on the horizontal plate 832, and the first rack 85 is arranged along the first direction on the bottom wall of the inner cavity of the first box, so that the laser head 7 can be driven by the first drive motor 84 to slide on the first slide rail 81 of the inner cavity of the first box along the first direction. In addition, the second reflector 62 is also arranged on the bottom wall of the inner cavity of the first box body, and the light inlet of the second reflector 62 is in the same straight line as the light outlet of the first reflector 61, and the light outlet of the second reflector 62 is in the same straight line as the light inlet of the third reflector 63 on the laser head 7, and the straight line direction of the light inlet of the second reflector 62 and the light outlet of the first reflector 61 is perpendicular to the straight line direction of the light outlet of the second reflector 62 and the light inlet of the third reflector 63 on the laser head 7.

[0073] Furthermore, the other end of the first cutting platform 1 is adjustable and provided with a console 14. Of course, the laser power of the laser 5, the motor speed of the first drive motor 84, the motor speed of the second drive motor 91, etc. can be debugged through the console 14.

[0074] It is worth noting that the console 14, vacuum pump 33, laser 5, laser assembly 6, first reflector 61, second reflector 62, third reflector 63, laser head 7, brush 71, first drive motor 84, second drive motor 91, and third drive motor in this application can all be implemented using products in the existing technology, and the principles and structures will not be described one by one here.

[0075] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
