Detailed Implementation

[0042] 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.

[0043] 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.

[0044] This application provides a laser engraving device for double-sided engraving of steel strips, including: a laser engraving device body 1, two support frames 101 mounted on the top of the laser engraving device body 1, extension frames 102 mounted on both sides of the top of the two support frames 101, a control console 10 mounted on one side of the outer end of the laser engraving device body 1, a display screen and multiple control buttons mounted on the control console 10, a laser engraving assembly mounted on the top of the laser engraving device body 1, the laser engraving assembly including: a first uniform speed motor 2, a first motor shaft 201, a feeding tray 202, a first laser platform 203, a second laser platform 204, a laser generator 205 and a laser head 206, and a clamping assembly mounted on the laser engraving device body 1, the clamping assembly including: an electric lifting cylinder 3, a telescopic rod 301, a mounting head 302, a first clamping block 303, a second clamping block 304 and a connecting rod 305.

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0047] Example 1 of the laser engraving equipment for double-sided engraving steel strips in this application

[0048] The laser engraving equipment for double-sided engraving of steel strips in this application includes: a laser engraving equipment body 1, with two support frames 101 mounted on the top of the laser engraving equipment body 1, and extension frames 102 mounted on both sides of the top of the two support frames 101. A control console 10 is mounted on one side of the outer end of the laser engraving equipment body 1, with a display screen and multiple control buttons mounted on the control console 10. A laser engraving component is set on the top of the laser engraving equipment body 1, and the laser engraving component includes: a first uniform speed motor 2, a first motor shaft 201, a feeding tray 202, a first laser platform 203, a second laser platform 204, a laser generator 205, and a laser head 206. A clamping component is set on the laser engraving equipment body 1, and the clamping component includes: an electric lifting cylinder 3, a telescopic rod 301, a mounting head 302, a first clamping block 303, a second clamping block 304, and a connecting rod 305.

[0049] A first uniform speed motor 2 is installed on one side of the top of the extension frame 102. A first motor shaft 201 is installed on the outer end of the first uniform speed motor 2. A feeding tray 202 is installed on the outer end of the first motor shaft 201. A first laser platform 203 is installed on one side of the top of the laser engraving equipment body 1. A second laser platform 204 is installed on one side of the first laser platform 203. Laser generators 205 are installed on both support frames 101 at positions relative to the first laser platform 203 and the second laser platform 204. A laser head 206 is installed at the bottom of each laser generator 205.

[0050] Among them, the laser engraving component adopts a dual-head laser engraving head, which can engrave both sides of the workpiece simultaneously. Compared with the traditional single-head single-sided engraving machine, it can improve the workpiece engraving production efficiency, reduce operation time and manual intervention, and solve the problem that traditional equipment requires multiple operations and repositioning when engraving on both sides. The clamping component clamps the steel strip onto the first laser platform 203 and the second laser platform 204 to ensure that the steel strip is placed flat and to avoid the steel strip protruding and affecting the processing quality, thereby ensuring the accuracy of the engraving spot.

[0051] In this embodiment, the workpiece is a steel strip, which is a thin, long strip structure with several card holder shapes stamped on it. The thin steel strip has a certain degree of flexibility. The steel strip to be processed is wound around the feeding tray 202. During the processing, the steel strip is introduced and placed on the first laser platform 203 and the second laser platform 204, so that the steel strip is positioned facing the laser head 206 and aligned with the laser head 206. The laser generator 205 is started by controlling the control machine 10. The laser generator 205 generates a high-energy laser beam, which is transmitted to the laser head 206 through an optical fiber. The laser beam passes through a focusing lens to form a high-energy-density spot for engraving on the surface of the workpiece. Two sets of engraving platforms are set up, namely the first laser platform 203, laser generator 205 and laser head 206 as one set, and the second laser platform 204, laser generator 205 and laser head 206 as another set, which can realize double-head, double-sided engraving processing of steel workpieces.

[0052] After the steel sheet workpiece surface is engraved on the first laser platform 203 by the laser generator 205 and laser head 206, the steel sheet strip is transmitted between the first laser platform 203 and the second laser platform 204 due to the gap between them. Since the thin steel sheet strip has a certain degree of flexibility, the middle section of the steel sheet strip between the first laser platform 203 and the second laser platform 204 is set as a flipping buffer section. For example, when the steel sheet strip enters the middle section after passing through the first laser platform 203 at the beginning, it is manually flipped and then introduced through the second laser platform 204, and finally enters the receiving tray 402. During the process of the motor driving the transmission of the steel sheet strip, the steel sheet strip passing through the middle section is still flipped and then transmitted. Thus, when the steel sheet is transported through the second laser platform 204 after surface engraving, it flips over so that the back of the steel sheet is directly opposite the laser head 206. The control console 10 controls another set of laser generators 205 to start working. The laser generators 205 generate a high-energy laser beam, which is transmitted to the laser head 206 through an optical fiber. The laser beam passes through a focusing lens to form a high-energy-density spot, which is used to engrave on the back of the workpiece. In this way, the back of the steel sheet can be engraved on the second laser platform 204.

[0053] Embodiment 2 of the laser engraving equipment for double-sided engraving steel strips in this application

[0054] The first laser platform 203 and the second laser platform 204 are each equipped with a mounting block 5 at their bottom. Mounting slots 501 are provided on both sides of the top of the mounting block 5. Several fixing screw holes 502 are provided on the top of the laser engraving equipment body 1. When in use, the first laser platform 203 and the second laser platform 204 can be installed on the top of the laser engraving equipment body 1 by using the mounting block 5, mounting slots 501, and fixing screw holes 502. Specifically, the mounting block 5 is placed on the top of the laser engraving equipment body 1, the mounting slots 501 are aligned with the fixing screw holes 502, and a screw is inserted from the mounting slot 501 into the fixing screw hole 502 and tightened to fix the mounting block 5 on the top of the laser engraving equipment body 1. This ensures that the first laser platform 203 and the second laser platform 204 are stably placed for use. The multiple fixing screw holes 502 allow for flexible adjustment of the installation distance between the first laser platform 203 and the second laser platform 204.

[0055] The extension frame 102 has an installation rod 8 installed on one side of its bottom. The outer end of the installation rod 8 is equipped with a feeding tray 801. The feeding tray 801 is located at the bottom of the feeding tray 202. The outer end of the feeding tray 801 has a curved structure. When the steel strip is introduced from the feeding tray 202 onto the first laser platform 203, the feeding tray 801 and the first laser platform 203 are on the same horizontal line. The setting of the feeding tray 801 can support and place the steel strip, prevent the steel strip from sinking during the transmission process, ensure that the steel strip is transmitted in parallel, and avoid affecting the engraving quality of the steel strip. In addition, the curved structure of the outer end of the feeding tray 801 can prevent wear between the steel strip and the feeding tray 801.

[0056] Among them, a second uniform speed motor 4 is installed on the side of the top of the extension frame 102 away from the first uniform speed motor 2. A second motor shaft 401 is installed on the outer end of the second uniform speed motor 4. A receiving tray 402 is installed on the outer end of the second motor shaft 401. A support rod 9 is installed on one side of the top of the laser engraving equipment body 1. A receiving tray 901 is installed on the top of the support rod 9. The receiving tray 901 is located at the bottom of the receiving tray 402. The outer end of the receiving tray 901 has a curved structure.

[0057] When engraving steel sheet workpieces, the control table 10 controls the first uniform speed motor 2 and the second uniform speed motor 4 to start working synchronously. They can drive the feeding tray 202 and the receiving tray 402 to rotate synchronously at a uniform speed. That is, the feeding tray 202 releases the steel sheet strip onto the first laser platform 203 and the second laser platform 204 for engraving. After the steel sheet workpiece is engraved on both sides on the first laser platform 203 and the second laser platform 204, the engraved steel sheet strip is rewound by the receiving tray 402 for easy storage.

[0058] Embodiment 3 of the laser engraving equipment for double-sided engraving steel strips in this application

[0059] Based on Embodiment 1 and Embodiment 2, an electric lifting cylinder 3 is installed on the outer side of both the first laser platform 203 and the second laser platform 204. The top of the electric lifting cylinder 3 is provided with a telescopic rod 301, the top of the telescopic rod 301 is provided with an installation head 302, the outer end of the installation head 302 is provided with a first clamping block 303, the outer side of the first clamping block 303 is provided with a second clamping block 304, and a connecting rod 305 is installed between the two ends of the second clamping block 304 and the first clamping block 303.

[0060] In the engraving process of steel sheet workpieces on the first laser platform 203 and the second laser platform 204, when the steel sheet is aligned with the laser head 206, the electric lifting cylinder 3 is controlled by the control machine 10 to drive the telescopic rod 301 to move downward. The telescopic rod 301 drives the mounting head 302, the first clamping block 303 and the second clamping block 304 to move downward and contact the steel sheet strip. The first clamping block 303 and the second clamping block 304 clamp the two sides of the steel sheet strip, so that the steel sheet is exposed and aligned with the laser head 206, which facilitates the laser head 206 to engrave the steel sheet. When the steel sheet strip is clamped and placed on the first laser platform 203 and the second laser platform 204, it is ensured that the steel sheet is placed flat to avoid the steel sheet protruding and affecting the processing quality, thereby ensuring the accuracy of the engraving spot.

[0061] After the steel sheet of the clamping part is engraved, the electric lifting cylinder 3 is controlled by the control machine 10 to drive the telescopic rod 301 to move upward. The telescopic rod 301 drives the mounting head 302, the first clamping block 303 and the second clamping block 304 to move upward and move away from the steel sheet material strip, releasing the clamping of the steel sheet material strip, so that the steel sheet material strip can continue to be transmitted and moved, which is convenient for processing the unengraved parts.

[0062] Among them, the mounting block 5 has a fixing block 6 installed on both sides of the top, the fixing block 6 has a servo motor 601 installed on the top, the servo motor 601 has a rotating shaft 602 installed at one end, the rotating shaft 602 has a turntable 603 installed at one end, and the turntable 603 has multiple protrusions 604 installed on the outer circumference of the outer ring. The first laser platform 203 and the second laser platform 204 have movable grooves 605 on both sides of the top. The turntable 603 is located inside the movable groove 605, and the top of the turntable 603 is flush with the top of the movable groove 605.

[0063] During the engraving process, the steel strip is placed on the first laser platform 203 and the second laser platform 204. The steel strip is located at the top of the movable groove 605. At this time, the bottom of the steel strip is in contact with the protrusion 604 on the top of the turntable 603. After the steel strip is released from clamping, the servo motors 601 on the first laser platform 203 and the second laser platform 204 are started synchronously by controlling the control machine 10. The servo motors 601 drive the rotating shaft 602 to drive the turntable 603 to rotate, which in turn drives the steel strip to be transported on the first laser platform 203 and the second laser platform 204. This reduces the resistance during the transport of the steel strip and ensures smooth feeding and receiving between the feeding tray 202 and the receiving tray 402.

[0064] Each laser generator 205 is equipped with a mounting bracket 7 on its top, and a cooling fan 701 is installed at the bottom of each mounting bracket 7. During use, the cooling fan 701 is started by controlling the control panel 10 to blow air onto the laser generator 205 and the laser head 206 to cool them down and prevent them from getting cold, thus ensuring the equipment can operate stably for a long time.

[0065] The laser engraving equipment body 1 has a control console 10 installed on one side of its outer end. The control console 10 is equipped with a display screen and multiple control buttons. When the first uniform speed motor 2, laser generator 205, laser head 206, electric lifting cylinder 3, second uniform speed motor 4, servo motor 601, and cooling fan 701 are in use, they are electrically connected to the control console 10. The multiple control buttons on the control console 10 can control the first uniform speed motor 2, laser generator 205, laser head 206, electric lifting cylinder 3, second uniform speed motor 4, servo motor 601, and cooling fan 701 to start or stop. The power of the laser engraving equipment body 1 in this application is provided by an external power source. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0066] Example 4 of the laser engraving equipment for double-sided engraving steel strips in this application

[0067] Based on any one of Embodiments 1 to 3, a reversing table 207 is installed between the first laser platform 203 and the second laser platform 204. A first fixing frame 208 is installed on the top of the reversing table 207 near the first laser platform 203. Two guide rollers 209 are rotatably connected inside the first fixing frame 208 via a rotating shaft. A second fixing frame 210 is installed on one side of the first fixing frame 208. Two vertical rollers 211 are rotatably connected inside the second fixing frame 210 via a rotating shaft. A third fixing frame 212 is installed on one side of the second fixing frame 210. Two flipping rollers 213 are rotatably connected inside the third fixing frame 212 via a rotating shaft. The two guide rollers 209 are arranged at an inclination of 45°, and the two guide rollers 209 and the two flipping rollers 213 are mirror-symmetrically arranged.

[0068] After the steel sheet workpiece surface is engraved on the first laser platform 203 by the laser generator 205 and laser head 206, a gap is left between the first laser platform 203 and the second laser platform 204, and a reversing table 207 is installed between the first laser platform 203 and the second laser platform 204 to guide the steel sheet strip between the first laser platform 203 and the second laser platform 204 for face changing. Due to the certain flexibility of the thin steel sheet strip, the steel sheet strip is pulled from the first laser platform 203 between the two guide rollers 209 and through the two vertical rollers 211, then led out from the two turning rollers 213 onto the second laser platform 204, and finally guided to the receiving tray 402, passing through the guide rollers 209 and the vertical rollers 211. The arrangement of rollers 211 and 213, and the 45° inclined structure of the two guide rollers 209, with the two guide rollers 209 and the two 213 arranged in a mirror symmetrical manner, ensures that the steel sheet of the steel strip is flipped over when it is transferred to the second laser platform 204 after surface engraving on the first laser platform 203. The back of the steel sheet is directly opposite the laser head 206. The control machine 10 controls another set of laser generators 205 to start working. The laser generator 205 generates a high-energy laser beam, which is transmitted to the laser head 206 through an optical fiber. The laser beam passes through a focusing lens to form a high-energy-density spot for engraving on the back of the workpiece. Thus, the back of the steel sheet can be engraved on the second laser platform 204.
