Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and in particular to a laser marking device and a tab production line. Background Technology

[0002] Laser marking devices are equipment that use laser technology to mark and code on the surface of various materials. Due to their strong permanence, high anti-counterfeiting properties, high precision, strong wear resistance, and safety and reliability, they are widely used. For example, in the food industry, laser marking devices can be used to label food packaging with information such as production date, shelf life, and place of origin, ensuring food safety and traceability. In the battery industry, laser marking devices can be used to mark battery tabs to achieve product quality tracking and anti-counterfeiting.

[0003] Currently, conventional laser marking devices include a laser generator and a focusing linear module for fine-tuning the laser generator. The laser generator is typically a cuboid structure and is often cantilevered, meaning one end of the laser generator is fixed while the other end is suspended; or the middle is fixed while both ends are suspended. This cantilevered mounting and the use of a linear module amplify vibrations when the laser marking device is subjected to vibration, causing problems such as marking point drift and marking shape deformation, affecting the accuracy and quality of laser marking.

[0009] A support platform is provided outside the housing, and the support platform is provided with a support surface;

[0010] A laser generator is used to mark the tape to be marked. The laser generator includes a main body and an emitting part that can emit laser light.

[0014] In one exemplary embodiment, the support platform includes a fixing member and an adjusting bolt. The fixing member is spaced apart from the lifting member. One end of the adjusting bolt is movably mounted on the fixing member, and the other end of the adjusting bolt abuts against the lifting member.

[0015] In one exemplary embodiment, the support platform includes a mounting member, the support plate having a mounting hole, the mounting member passing through the mounting hole to connect to the laser generator, the mounting hole extending in a direction away from the housing, so that the laser generator can move in a direction closer to or away from the housing.

[0016] In one exemplary embodiment, the support platform includes a shock absorber disposed between the laser generator and the support surface.

[0017] In an exemplary embodiment, the positioning component includes a limiting roller, the conveying roller and the limiting roller are arranged from bottom to top along the height direction of the housing, and a gap is formed between the conveying roller and the limiting roller; the coding tape is passed through the gap, and the conveying roller and the limiting roller respectively abut against the coding tape.

[0018] In one exemplary embodiment, the positioning component includes an adjusting member disposed on the inner sidewall of the housing.

The adjusting part is vertically and vertically disposed at the bottom of the main body, and the end of the adjusting part is accommodated in the adjusting hole and abuts against the limiting roller, so that the limiting roller can move up and down relative to the housing with the adjustment part.

[0020] In one exemplary embodiment, the bottom of the housing is provided with an inclined plate, which is located below the positioning component.

[0021] A tab production line includes the laser marking device described above.

[0022] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0023] This utility model discloses a laser marking device, comprising a housing, a laser generator, a support platform, and a positioning assembly. The laser generator includes a main body and an emitting part, with the emitting part facing an opening at the top of the housing so that the laser emitted by the emitting part can penetrate the interior of the housing to mark the strip to be marked inside. The support platform is located outside the housing and has a support surface for supporting the bottom surface of the main body of the laser generator. Compared to a cantilevered mounting method for the laser generator, the support platform of this application effectively improves the stability of the laser generator, reduces the impact of vibration on its operation, and thus helps to improve the marking yield and laser marking accuracy of the laser marking device.

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] This utility model provides a laser marking device 100 with good stability and high marking accuracy. The specific solution is described through the following embodiments.

[0036] It should be noted that the laser marking device 100 of this application is used to laser mark strip-shaped objects. For ease of description, strip-shaped items will be referred to as marking strips in the following text.

[0037] See Figure 1 and Figure 2 The laser marking device 100 includes a housing 10 and a laser generator 20.

[0038] The housing 10 has through holes 11 on opposite sides. The tape to be labeled can enter the housing 10 through one through hole 11 and move to the outside of the housing 10 through another through hole 11.

[0039] The laser generator 20 is used to mark the tape to be marked. Specifically, the top of the housing 10 has an opening 12. The laser generator 20 includes a main body 21 and an emitting part 22. The end of the main body 21 is connected to the emitting part 22. The emitting part 22 is capable of emitting laser. The emitting part 22 is arranged corresponding to the opening 12 on the housing 10 so that the laser emitted by the emitting part 22 can enter the interior of the housing 10 and mark the tape to be marked inside the housing 10.

[0040] The laser generator 20 can be provided in multiple ways, so that multiple coding strips can be laser-coded at the same time, or different areas of the same coding strip can be laser-coded at the same time, which can effectively improve coding efficiency.

[0041] This embodiment uses two laser generators 20, each capable of laser marking different strips to be marked, as an example. When multiple strips to be marked are inserted into the housing 10, they are typically spaced apart. Therefore, the laser generators 20 can be arranged adjacently or spaced apart along the direction of travel of the strips. Furthermore, along the direction perpendicular to the direction of travel of the strips, the laser generators 20 are staggered to correspond to the multiple strips to be marked, thereby achieving laser marking of the multiple strips.

[0042] Please see Figure 1 and Figure 2The laser marking device 100 includes a support platform 30. The support platform 30 is located outside the housing 10. The support platform 30 has a support surface 311. The bottom surface of the main body 21 of the laser generator 20 is supported by the support surface 311. The support surface 311 can support all or most of the bottom surface of the main body 21. Compared with the laser generator 20 which is cantilevered, this application provides stable support for the laser generator 20 by setting the support platform 30, effectively reducing the impact of vibration on the laser generator 20, thereby improving the stability of the marking operation and effectively improving the marking yield of the laser marking device 100 on the tape to be marked. In addition, the laser marking device 100 in this application is suitable for marking products with small size and high precision requirements.

[0043] Furthermore, the center of gravity of the laser generator 20 is located on the support platform 30, which greatly improves the installation stability of the laser generator 20 and reduces the impact of vibration on the laser generator 20 compared to the cantilever installation structure.

[0044] See Figure 2 and Figure 3 In some embodiments, the support platform 30 includes a support plate 31 and a mounting member 32. The support plate 31 is disposed on the top of the housing 10. The support surface 311 is the surface of the support plate 31 facing away from the housing 10. The support plate 31 is provided with mounting holes 312. The mounting member 32 can pass through the mounting holes 312 and be connected to the body 21 of the laser generator 20, thereby fixing the laser generator 20 to the support plate 31.

[0045] Multiple mounting members 32 are provided to ensure a stable connection between the laser emitter and the support plate 31. For example, the outer contour of the main body 21 of the laser generator 20 is approximately rectangular. Four mounting members 32 are provided, each corresponding to one of the four corners of the main body 21.

[0046] In some embodiments, the mounting hole 312 extends away from the housing 10. Therefore, the operator can adjust the horizontal position of the laser generator 20 according to the position of the tape to be marked, so that the laser generator 20 can move horizontally toward or away from the housing 10, so that the laser emitted by the laser generator 20 can accurately mark the tape to be marked.

[0047] In some embodiments, the laser marking device 100 includes a shock absorber 33 disposed between the laser generator 20 and the support surface 311 of the support plate 31 to isolate and mitigate vibration. Exemplarily, the shock absorber 33 may be disposed on the mounting member 32, with one end of the shock absorber 33 in contact with the bottom surface of the main body 21 of the laser generator 20 and the other end in contact with the support surface 311 of the support plate 31. The shock absorber 33 may be a damping adhesive or the like.

[0048] See Figure 3and Figure 4 In some embodiments, the support platform 30 includes a lifting member 34. The lifting member 34 is vertically and flexibly disposed outside the housing 10. The lifting member 34 is connected to the support plate 31, so that the support plate 31 can move relatively closer to or further away from the housing 10 along the height direction of the housing 10, thereby enabling adjustment of the height distance between the laser generator 20 and the coding tape to be marked, so that the laser emitted by the laser generator 20 can be correctly focused, thereby forming a clear mark on the surface of the coding tape.

[0049] See Figure 4 and Figure 5 Specifically, in this embodiment, the lifting member 34 is provided with multiple vertical holes 341. The extending direction of the vertical holes 341 is consistent with the height direction of the housing 10. The housing 10 is provided with mounting holes 13 corresponding to the vertical holes 341. The support platform 30 includes fasteners (not shown). The fasteners can pass through the vertical holes 341 and the mounting holes 13 in sequence, and the ends of the fasteners are in contact with the surface of the lifting member 34 to fix the lifting member 34 to the housing 10. The fasteners can be bolts, screws, etc.

[0050] It is understandable that the vertical hole 341 is provided to ensure that the lifting component 34 can be stably installed on the housing 10, while also enabling the lifting component 34 to move smoothly up and down. Specifically, when it is necessary to adjust the height of the laser generator 20, the fasteners can be loosened without having to be removed, as long as the lifting component 34 can move relative to the housing 10. After the lifting component 34 is adjusted to the appropriate height, the fasteners are tightened to fix the lifting component 34 to the housing 10.

[0051] See Figure 4 In some embodiments, the support platform 30 includes a fixing member 35 and an adjusting bolt (not shown). The fixing member 35 and the lifting member 34 are spaced apart. One end of the adjusting bolt is movably mounted on the fixing member 35, and the other end of the adjusting bolt abuts against the lifting member 34. The fixing member 35 and the adjusting bolt work together to achieve the lifting of the lifting member 34.

[0052] Specifically, the fixing member 35 includes a fixing part 351 and a bending part 352. The fixing part 351 has a through hole 353. The side wall of the housing 10 has a fastening hole 14. The fitting can pass through the through hole 353 and the fastening hole 14 to fasten the fixing part 351 to the housing 10. The bending part 352 can be provided at the end of the fixing part 351 near the lifting member 34 and extends in a direction away from the housing 10. The bending part 352 has a threaded hole 354. The end of the adjusting bolt can pass through the threaded hole 354 and abut against the lifting member 34.

[0053] Rotating the adjusting bolt forward moves it closer to the laser generator 20, thereby raising the lifting component 34. This increases the distance between the laser generator 20 and the coding tape within the housing 10, while maintaining a fixed height. Conversely, rotating the adjusting bolt in the opposite direction moves it away from the laser generator 20, causing the lifting component 34 to descend. This decreases the distance between the laser generator 20 and the coding tape within the housing 10, while maintaining a fixed height.

[0054] It should be noted that this embodiment makes full use of the small pitch of the adjusting bolt to achieve fine adjustment of the laser generator 20 along the height direction of the housing 10, ensuring that the coding strip is within the focal length range of the laser generator 20, thus achieving effective laser coding.

[0055] See Figure 3 In some embodiments, the support platform 30 includes a reinforcing member 36. Multiple reinforcing members 36 may be provided. The reinforcing members 36 are disposed between the lifting member 34 and the support plate 31 to enhance the stability of the support plate 31.

[0056] For example, the outer contour of the reinforcing member 36 has an approximately "L" shaped structure. The reinforcing member 36 includes a vertical portion 361 and a horizontal portion 362. The vertical portion 361 is connected to the lifting member 34, and the extending direction of the vertical portion 361 is the same as the extending direction of the lifting member 34. The horizontal portion 362 is connected to the support plate 31, and the extending direction of the horizontal portion 362 is the same as the extending direction of the support plate 31. The vertical portion 361 and the horizontal portion 362 are connected, and an arc-shaped portion 363 is formed at the connection point to effectively reduce stress concentration, which is beneficial to improving the structural stability and durability of the support platform 30.

[0057] In this embodiment, the reinforcing member 36 and the lifting member 34 are detachably connected. In other embodiments, the reinforcing member 36 can be fixedly connected to the lifting member 34, for example, by welding. Alternatively, the reinforcing member 36 can be integrally formed with the lifting member 34.

[0058] Furthermore, it is understood that since the reinforcing member 36 is fixed to the lifting member 34, the aforementioned adjusting bolt can abut against the reinforcing member 36. Rotating the adjusting bolt will also allow the lifting member 34 to rise or fall. It should be noted that in some other embodiments, the lifting member 34 can be omitted, and the support plate 31 can be directly connected to the housing 10. In this case, the vertical portion 361 of the reinforcing member 36 can be connected to the outer wall of the housing 10. Alternatively, in other embodiments, the lifting member 34 and the reinforcing member 36 can be omitted, and the support plate 31 can be the top plate of the housing 10.

[0059] See Figure 5The laser marking device 100 includes a positioning component 40. The positioning component 40 is located inside the housing 10. The positioning component 40 is connected to the tape to be marked and is used to hold the tape at a set height inside the housing 10, so that the tape is within the focal depth range of the laser generator 20, which helps to improve the marking effect of the laser generator 20.

[0060] Multiple positioning components 40 can be provided. These multiple positioning components 40 can maintain different sections of the same coding tape at the same or different set heights; alternatively, multiple positioning components 40 can maintain the same or different set heights for different sections of multiple coding tapes. The specific number of positioning components 40 can be adaptively set according to actual needs such as the focal length of the laser generator 20. This embodiment uses two positioning components 40 as an example. The two positioning components 40 can be respectively located near the two through holes 11 on the housing 10.

[0061] In addition, the multiple positioning components 40 also facilitate the stable movement of the tape to be labeled within the housing 10.

[0062] Specifically, the positioning assembly 40 includes a conveyor roller 41 for conveying the tape to be encoded. In some embodiments, the two ends of the conveyor roller 41 may be connected to opposite side walls of the housing 10, respectively. The surface of the tape to be encoded facing away from the laser generator 20 is in contact with the surface of the conveyor roller 41. The conveyor roller 41 may be rotatably mounted on the housing 10 to reduce friction on the tape to be encoded, thus protecting the tape.

[0063] In the height direction of the housing 10, the sidewalls corresponding to the through holes 11 on the housing 10 are the upper sidewall and the lower sidewall, respectively. The upper surface of the conveyor roller 41 near the laser generator 20 is set higher than the lower sidewall to support the coding tape and prevent the surface of the coding tape from being damaged due to contact and friction with the lower sidewall when the coding tape passes through the through hole 11.

[0064] The positioning assembly 40 includes a limiting roller 42. The limiting roller 42 is used to limit the height position of the strip to be coded. Specifically, the conveyor roller 41 and the limiting roller 42 are arranged from bottom to top along the height direction of the housing 10. A gap is formed between the conveyor roller 41 and the limiting roller 42. The strip to be coded passes through the gap, and the opposite two side surfaces of the strip to be coded abut against the conveyor roller 41 and the limiting roller 42, respectively.

[0065] In addition, the lower surface of the limiting roller 42, which is away from the laser generator 20, is positioned lower than the upper sidewall to prevent the surface of the tape to be coded from being damaged due to contact and friction with the upper sidewall when the tape passes through the through hole 11.

[0066] It should be noted that the synergistic effect of the limiting roller 42 and the conveying roller 41 also helps to keep the strip to be marked flat, and prevents the strip to be marked from tilting or flipping during laser marking, thereby improving the marking effect.

[0067] In this embodiment, the limiting roller 42 is positioned closer to the outside of the housing 10 than the conveying roller 41. In other embodiments, the conveying roller 41 may also be positioned closer to the outside of the housing 10 than the limiting roller 42. The specific configuration can be determined according to actual conditions and is not limited here.

[0068] In some embodiments, the positioning assembly 40 includes an adjustment member 43. The adjustment member 43 is disposed on the inner sidewall of the housing 10.

[0069] See Figure 6 and combined Figure 1 In some embodiments, the side wall of the housing 10 may be provided with a first connecting hole 152 for fasteners to pass through. The adjusting member 43 is provided with a second connecting hole 436. The fastener passes through the first connecting hole 152 and is accommodated in the second connecting hole 436, thereby fixing the adjusting member 43 inside the housing 10. It should be noted that in other embodiments, the adjusting member 43 may also be provided on the inner wall of the housing 10 by other means, such as adhesive bonding, snap-fitting, etc.

[0070] Adjusting element 43 can adjust the height of conveying roller 41 within housing 10; or adjusting element 43 can adjust the height of limiting roller 42 within housing 10; or adjusting element 43 can adjust the heights of both conveying roller 41 and limiting roller 42 within housing 10. This embodiment will be described using the example of adjusting element 43 to adjust the height of limiting roller 42.

[0071] Specifically, the limiting roller 42 is provided with adjusting members 43 at both ends. The adjusting members 43 are connected to the limiting roller 42, so that the limiting roller 42 can be raised and lowered along the height direction of the box 10, thereby realizing the height adjustment of the coding tape.

[0072] See Figure 6 and Figure 7 In some embodiments, the adjusting member 43 includes a main body 431 and an adjusting part (not shown). The main body 431 is provided with an adjusting hole 432 extending along the height direction of the housing 10. The end of the limiting roller 42 is received in the adjusting hole 432. The adjusting part is vertically and vertically disposed at the bottom of the main body 431, and the end of the adjusting part is received in the adjusting hole 432 and abuts against the limiting roller 42, so that the limiting roller 42 can move up and down relative to the housing 10 with the adjustment part.

[0073] For example, the bottom of the main body 431 is provided with a limiting hole 433 communicating with the adjusting hole 432. The limiting hole 433 extends along the height direction of the housing 10. The adjusting part is correspondingly installed in the limiting hole 433. The top end of the adjusting part abuts against and supports the limiting roller 42, so rotating the adjusting part can raise or lower the limiting roller 42 relative to the housing 10. The adjusting part can be a bolt, stud, etc., and correspondingly, the limiting hole 433 on the main body 431 is a threaded hole 354 adapted to the adjusting part. It can be understood that this embodiment utilizes the thread of the adjusting part to achieve fine adjustment of the height of the limiting roller 42.

[0074] In some embodiments, the conveying roller 41 can be mounted on the adjusting member 43. The adjusting member 43 includes a fastening part (not shown). The main body 431 is provided with a fixing hole 434 and a receiving hole 435. The fixing hole 434 is closer to the laser generator 20 than the receiving hole 435. There are two receiving holes 435, and the ends of the conveying roller 41 and the limiting roller 42 are respectively received in the two receiving holes 435. There are two fixing holes 434. The two fixing holes 434 communicate with the two receiving holes 435 respectively. The fastening part passes through the fixing hole 434 and abuts against the limiting roller 42 and the conveying roller 41. The fastening part and the fixing hole 434 can enhance the stability of the conveying roller 41 and the limiting roller 42. The fastening part can be a bolt, stud, etc., and correspondingly, the fixing hole 434 on the main body 431 is a threaded hole 354 adapted to the fastening part.

[0075] It is understood that the receiving hole 435 at the end of the accommodating limiting roller 42 is the aforementioned adjusting hole 432. The end of the limiting roller is clamped between the bottom end of the fastening part and the top end of the adjusting part, which helps to enhance the stability of the limiting roller and reduce the impact of vibration on the limiting roller.

[0076] join Figure 1 and Figure 2 In some embodiments, an operating port (not shown) is provided on the side of the housing 10 opposite to the support platform 30. The operating port is connected to the interior of the housing 10. Therefore, the operator can operate the adjustment part on the adjustment member 43 through the operating port to make fine adjustments to the height of the limiting roller 42.

[0077] In some embodiments, the housing 10 includes a body 15, a protective door 16, and a hinge 161. An operating port and a through hole 11 are provided on the body 15. The protective door 16 can be mounted on the housing 10 via the hinge 161 and covers the operating port to prevent accidental laser leakage during laser marking and potential injury to the operator. The protective door 16 can be a protective glass door, which has good laser protection performance and visible light transmittance, allowing operators to observe the laser marking process through the protective glass door.

[0078] In some embodiments, the body 15 may have a notch 151 that communicates with the operating hole. The operator can quickly open the protective door 16 through the notch 151.

[0079] In some embodiments, the housing 10 includes a top plate 17, a bottom plate 18, and a shielding member 19. The top plate 17, the main body 15, and the bottom plate 18 surround and form the housing 10. An opening 12 is provided on the top plate 17. The shielding member 19 may be provided along the edge of the top plate 17, located on the outer periphery of the emitting part 22 in the laser generator 20, to enhance protection, prevent laser leakage, and effectively reduce the impact of the external environment on laser marking.

[0080] In some embodiments, the bottom of the housing 10 is provided with an inclined plate 50. The inclined plate 50 is positioned below the positioning assembly 40. When the laser generator 20 marks the tape to be marked, it generates smoke and dust. Therefore, the inclined plate 50 helps to concentrate the smoke and dust, making it easier to clean.

[0081] In some embodiments, the laser marking device 100 includes a fixing component 60, which is located at the bottom of the housing 10 and is used to fix the laser marking device 100 to an external platform, device or production line.

[0082] Exemplarily, the fixing component 60 includes a plate 61 and a transmission part 62. The plate 61 is connected to the base plate 18 of the housing 10. The transmission part 62 is disposed on the side of the plate 61 opposite to the base plate 18. The transmission part 62 facilitates the movement of the entire laser marking device 100. The transmission part 62 can be a slider, roller, etc.

[0083] In other embodiments, the transmission unit 62 may also be directly mounted on the bottom plate 18 of the housing 10.

[0084] In some embodiments, the fixing component 60 includes an extension 63. The extension 63 may be located on one side of the plate 61. When the laser marking device 100 moves to a suitable location via the transmission part 62, the extension 63 may be fixed to an external platform, production line, etc., by means of snap-fit, screw-fit, or other methods.

[0085] The laser marking device 100 in this application, by setting a support platform 30, effectively supports the laser generator 20, which helps to ensure the stability of the laser generator 20 and effectively reduces the impact of vibration on the laser generator 20. The support platform 30 is height-adjustable outside the housing 10, thereby enabling coarse adjustment of the height of the laser generator 20 so that the strip to be marked is within the focal length range of the laser generator 20. By setting a positioning component 40, the strip to be marked is held at a set height within the housing 10, ensuring that the strip is within the focal depth range of the laser generator 20, which helps to improve the marking effect of the laser generator 20. This application also provides a tab production line, which includes the aforementioned laser marking device 100. It is understood that in this case, the laser marking device 100 is used to mark tab strips.
