Description

Technical Field

[0001] This application relates to the field of laser cutting technology, and more specifically, to a laser cutting device. Background Technology

[0002] Currently, marking methods for steel plate parts include manual marking, pneumatic impact marking, plasma arc marking, laser marking, and inkjet marking. Each of these methods has its applicable scenarios. As enterprises' demands for marking increase, their requirements and expectations for marking clarity, durability, equipment processing speed, and processing area also rise. As a result, marking application technologies are constantly being updated, and new technologies are being tested. Among these, UV-curable inkjet marking technology involves the polymerization reaction of monomers and oligomers within the ink under ultraviolet light, allowing for instant curing. This results in strong adhesion, extremely fast drying speed, high hardness of the cured ink layer, and good wear resistance. Piezoelectric inkjet printing technology using UV ink is also known as UV inkjet printing.

[0003] Given the superior performance of UV inkjet marking and the increasing adoption of laser cutting machines across various industries, combining a UV inkjet marking device with the laser cutting head of a laser cutting machine can reduce equipment investment costs and expand the application range of existing laser cutting machines, especially for marking large-format panels. However, UV inkjet marking devices have certain requirements regarding temperature and environmental cleanliness. The high temperatures and sparks generated during laser cutting head operation can easily affect the UV inkjet marking device. Utility Model Content

Detailed Implementation

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0033] This application provides a laser cutting device, such as... Figures 1 to 6 As shown, the laser cutting equipment includes: a first lifting device 10, a second lifting device 20, a coding device 30, a laser cutting head 40, and a protective device 50; the coding device 30 is disposed on the moving end of the first lifting device 10, and the first lifting device 10 is used to drive the coding device 30 to reciprocate between a standby position and a working position in the vertical direction; the protective device 50 is disposed on one side of the coding device 30, and when the coding device 30 is in the standby position, the protective device 50 is used to shield the coding device 30; the laser cutting head 40 is disposed on the moving end of the second lifting device 20, and the second lifting device 20 is used to drive the laser cutting head 40 to reciprocate in the vertical direction.

[0034] The working principle of the laser cutting equipment provided in this application embodiment is as follows: When it is necessary to print and cut the product to be marked, the product to be marked is placed below the printing device 30 and the laser cutting head 40. Before printing the product to be marked, that is, before the moving end of the first lifting device 10 drives the printing device 30 to move towards the product to be marked, the protective device 50 first removes the obstruction of the printing device 30. Then, the moving end of the first lifting device 10 drives the printing device 30 to move towards the product to be marked to the working position, and the printing device 30 prints the product to be marked. After the printing is completed, the moving end of the first lifting device 10 drives the printing device 30 to move away from the product to the standby position, and then the protective device 50 obstructs the printing device 30. Next, the moving end of the second lifting device 20 drives the laser cutting head 40 to move towards the product to be marked, and then the laser cutting head 40 cuts the product to be marked. After the cutting is completed, the moving end of the second lifting device 20 drives the laser cutting head 40 to move away from the product to be marked. Of course, it is also possible to simply inkjet print or cut the product to be marked, but this application will not elaborate on that.

[0035] In this embodiment, the working position refers to the position where the coding device 30 performs coding on the product to be marked, rather than a specific fixed position. The working position of the coding device 30 varies depending on the product to be marked. The first lifting device 10 moves the coding device 30 towards the product to be marked, and the working position is the position where the coding device 30 stops moving when the first lifting device 10 stops. Similarly, when the second lifting device 20 moves the laser cutting head 40 towards the product to be marked, its stopping position is also not a specific fixed position.

[0036] The beneficial effects of the laser cutting equipment provided in this application embodiment are as follows: the coding device 30 and the laser cutting head 40 are integrated into the laser cutting setup, and a protective device 50 is provided to shield the coding device 30 when it is in the standby position, so as not to hinder the coding operation of the coding device 30 when it is in the working position, and to avoid the impact of the high temperature and sparks generated by the laser cutting head 40 on the coding device 30, thereby improving the service life of the coding device 30; in addition, the coding device 30 and the laser cutting head 40 are driven by the first lifting device 10 and the second lifting device 20 respectively, so that the coding device 30 and the laser cutting head 40 can work independently, thereby improving the applicable scenarios of the laser cutting equipment.

[0037] In this embodiment, the vertical direction is the Z-axis direction in the attached figure.

[0038] like Figure 5 and Figure 6 As shown, the protective device 50 further includes a baffle 51 and a drive assembly 52. ​​The drive assembly 52 is located on one side of the inkjet printer 30. The baffle 51 is connected to the drive assembly 52. ​​The drive assembly 52 is used to drive the baffle 51 to rotate between a horizontal plane and a vertical plane. When the inkjet printer 30 is in the standby position, the baffle 51 is located on a horizontal plane to block the inkjet printer 30.

[0039] In this embodiment, when the product to be marked needs to be inkjet-copied, the product to be marked is placed below the inkjet-copied device 30. Before the product to be marked is inkjet-copied, that is, before the moving end of the first lifting device 10 drives the inkjet-copied device 30 to move towards the product to be marked, the driving component 52 drives the baffle 51 to rotate from the horizontal plane to the vertical plane to remove the obstruction of the inkjet-copied device 30. Then, the moving end of the first lifting device 10 drives the inkjet-copied device 30 to move towards the product to be marked to the working position, and the inkjet-copied device 30 marks the product to be marked. After the marking is completed, the moving end of the first lifting device 10 drives the inkjet-copied device 30 to move away from the product to the standby position. Then, the driving component 52 drives the baffle 51 to rotate from the vertical plane to the horizontal plane to block the inkjet-copied device 30.

[0040] In this embodiment, the baffle 51 is driven to rotate between the horizontal and vertical planes by the drive component 52 to block or remove the blockage of the inkjet printer 30. Its structure is simple and can reduce the occurrence of malfunctions of the protective device 50.

[0041] Further, the drive assembly 52 includes a rotating shaft 521, a connecting block 522, and a lifting member 523. The protective device 50 includes a first mounting base 53. The first mounting base 53 is located on one side of the inkjet printer 30. The lifting member 523 is vertically mounted on the first mounting base 53. The rotating shaft 521 is rotatably mounted on the first mounting base 53 and is perpendicular to the lifting member 523. The connecting block 522 is rotatably connected to the drive end of the lifting member 523. One end of the connecting block 522 away from the lifting member 523 is connected to the rotating shaft 521. The baffle 51 is mounted on the rotating shaft 521.

[0042] In this embodiment, when the product to be marked needs to be inkjet-printed, the product to be marked is placed below the inkjet-printing device 30. Before the product to be marked is inkjet-printed, that is, before the moving end of the first lifting device 10 drives the inkjet-printing device 30 to move towards the product to be marked, the driving end of the lifting member 523 retracts and drives the connecting block 522 to move downward. The rotating shaft 521 is driven to rotate by the connecting block 522, so that the baffle 51 rotates from the horizontal plane to the vertical plane to remove the obstruction of the inkjet-printing device 30. Then, the moving end of the first lifting device 10 drives the inkjet-printing device 30 to move towards the product to be marked to the working position, and the inkjet-printing device 30 marks the product to be marked. After the inkjet-printing is completed, the moving end of the first lifting device 10 drives the inkjet-printing device 30 to move away from the product to be marked to the standby position. Then, the driving end of the lifting member 523 extends and drives the connecting block 522 to move upward. The rotating shaft 521 is driven to rotate by the connecting block 522, so that the baffle 51 rotates from the vertical plane to the horizontal plane to block the inkjet-printing device 30.

[0043] In this embodiment, since the rotating shaft 521 is rotatably mounted on the first mounting base 53, the movement of the connecting block 522 will not cause the position of the rotating shaft 521 to move, but will cause the rotating shaft 521 to rotate on the first mounting base 53, thereby realizing the rotation of the baffle 51.

[0044] In this embodiment, the lifting component 523 is a cylinder; the driving end of the lifting component 523 is a cylinder rod.

[0045] like Figure 2 and Figure 3 As shown, the inkjet printer 30 further includes an inkjet header 31 and a steering mechanism 32. The steering mechanism 32 is located on the moving end of the first lifting device 10, and the inkjet header 31 is located on the steering mechanism 32. The steering mechanism 32 is used to drive the inkjet header 31 to rotate, and the protective device 50 is used to shield the inkjet header 31.

[0046] In this embodiment, when it is necessary to perform oblique inkjet printing on the product to be marked, the steering mechanism 32 drives the inkjet nozzle 31 to rotate.

[0047] In this embodiment, the spray nozzle 31 is equipped with an ultraviolet lamp (not shown), which can fully illuminate the markings sprayed from the spray nozzle 31.

[0048] Furthermore, the steering mechanism 32 includes a first support frame 321, a second support frame 322, and a rotary motor 323; the first support frame 321 is disposed on the moving end of the first lifting device 10, the rotary motor 323 is disposed on the first support frame 321, the second support frame 322 is connected to the output shaft of the rotary motor 323, and the spray nozzle 31 is disposed on the second support frame 322.

[0049] In this embodiment, the rotary motor 323 is mounted on the moving end of the first lifting device 10 by the first support frame 321 to avoid interference between the rotary motor 323 and the first lifting device 10. The spray dock 31 and the rotary motor 323 are mounted together by the second support frame 322 to avoid interference between the spray dock 31 and the rotary motor 323.

[0050] In this embodiment, when it is necessary to perform oblique inkjet printing on the product to be marked, the output shaft of the rotary motor 323 rotates to drive the second support frame 322 and the inkjet nozzle 31 to rotate.

[0051] Furthermore, the coding device 30 also includes a sensor 33, which is mounted on the second support frame 322. The sensor 33 is used to identify the product to be marked and to obtain the distance between the steering mechanism 32 and the product to be marked.

[0052] In this embodiment, sensor 33 is provided so that the inkjet printer 30 can be moved above the product to be marked and to the working position, and to avoid collision with the product to be marked, thereby improving the processing accuracy.

[0053] In this embodiment, the number of sensors 33 is one or more, and this application does not impose any limitation.

[0054] Furthermore, the coding device 30 also includes an ink supply mechanism 34, which is connected to the first lifting device 10 and connected to the inkjet terminal 31 via a pipe (not shown). The ink supply mechanism 34 is used to supply ink to the inkjet terminal 31.

[0055] In this embodiment, the ink supply mechanism 34 is connected to the first lifting device 10 and does not move with the inkjet nozzle 31, which can reduce ink leakage of the ink supply mechanism 34.

[0056] Furthermore, the laser cutting equipment includes a first linear module 60, which includes a drive module (not shown) and a slider (not shown). The drive module is used to drive the protective device 50, the first lifting device 10, and the second lifting device 20 to move along a first horizontal direction.

[0057] like Figure 1 As shown, in this embodiment, the number of drive modules is one, and the protective device 50, the first lifting device 10 and the second lifting device 20 are disposed on the slider.

[0058] In the above embodiments, when the first linear module 60 includes a drive module, the protective device 50, the first lifting device 10 and the second lifting device 20 move synchronously in the first horizontal direction, which can prevent the coding device 30 and the laser cutting head 40 from colliding.

[0059] Alternatively, in another embodiment, the number of drive modules is two, with the protective device 50 and the second lifting device 20 disposed on one of the sliders, and the second lifting device 20 disposed on the other slider.

[0060] In the above embodiment, the first linear module 60 includes two drive modules, and the first lifting device 10 and the second lifting device 20 are respectively mounted on the two drive modules. When the laser cutting head 40 is working, the drive modules can drive the first lifting device 10 and the inkjet printer 30 to move away from the laser cutting head 40, further reducing the impact of the laser cutting head 40 on the inkjet printer 30 when it is working.

[0061] In this embodiment, the first horizontal direction is the Y-axis in the attached figure.

[0062] Furthermore, the drive module also includes a motor (not shown) and a lead screw (not shown), the lead screw being connected to the motor, and the slider sliding on the lead screw; in this embodiment, the motor drives the lead screw to rotate, causing the slider to slide on the lead screw, thereby moving the protective device 50, the first lifting device 10 and the second lifting device 20 provided on the slider.

[0063] Furthermore, both the first lifting device 10 and the second lifting device 20 are linear modules; the structure of the first lifting device 10 and the second lifting device 20 is consistent with the structure of the first linear module 60, and the moving end of the first lifting device 10 and the moving end of the second lifting device 20 are sliders, which will not be described in detail here.

[0064] Furthermore, the laser cutting equipment also includes a second mounting base 70, which is disposed on the slider.

[0065] In this embodiment, when the first linear module 60 includes a drive module, the number of second mounting bases 70 is one, and the protective device 50, the first lifting device 10, and the second lifting device 20 are disposed on the same second mounting base 70; or, in another embodiment, when the first linear module 60 includes two drive modules, the number of second mounting bases 70 is two, the protective device 50 and the first lifting device 10 are disposed on the same second mounting base 70, and the second lifting device 20 is disposed on another second mounting base 70.

[0066] In the above embodiment, the protective device 50 and the first lifting device 10 are mounted on a second mounting base 70, so that the protective device 50 and the inkjet printer 30 are arranged adjacent to each other, so as to ensure that the protective device 50 can block the inkjet printer 30.

[0067] Furthermore, the ink supply mechanism 34 and the first lifting device 10 are located on opposite sides of the second mounting base 70, and the first mounting base 53 is located on the second mounting base 70 and is arranged adjacent to the first lifting device 10.

[0068] like Figure 1 As shown, the laser cutting equipment further includes a second linear module 80, on which the first linear module 60 is disposed, and the second linear module 80 is used to drive the first linear module 60 to move along a second horizontal direction.

[0069] In this embodiment, the second horizontal direction is the X-axis in the attached figure.

[0070] In this embodiment, through the cooperation of the first linear module 60, the second linear module 80, the first lifting device 10, and the second lifting device 20, multi-directional movement of the inkjet printer 30 and the laser cutting head 40 along the X, Y, and Z axes can be achieved; through the cooperation of the first linear module 60, the second linear module 80, and the inkjet printer 30, the product to be marked can achieve... Figure 4 The special markings shown.

[0071] In this embodiment, the second linear module 80 has the same structure as the first linear module 60 and also includes a drive module. The first linear module 60 is mounted on the slider of the second linear module 80, which will not be described in detail here.

[0072] Furthermore, the laser cutting equipment also includes a worktable 90, which is used to place the product to be marked, and the second linear module 80 is arranged along the length direction of the worktable 90.

[0073] Furthermore, the laser cutting equipment also includes a control device 100, which is electrically connected to the first lifting device 10, the second lifting device 20, the coding device 30, the laser cutting head 40, the protective device 50, the first linear module 60, and the second linear module 80; the control device 100 is used to control the operation of the first lifting device 10, the second lifting device 20, the coding device 30, the laser cutting head 40, the protective device 50, the first linear module 60, and the second linear module 80.

[0074] In this embodiment, the control device 100 can improve the coordination between the various devices of the laser cutting equipment, and the operator can control the operation of each device in the control device 100.

[0075] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.

This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
