Description

Technical Field

[0001] This utility model relates to the field of pipe engraving technology, and more specifically, to a laser engraving device. Background Technology

[0002] Insertion tubes are a key component of medical devices such as endoscopes. In clinical applications, doctors need to monitor the depth of the insertion tube into the human body in real time according to the needs of the surgery. Therefore, clear and easily identifiable scale markings are usually set on the outer surface of the insertion tube to assist in positioning and operation.

[0003] Currently, scale markings are mostly processed using laser engraving. However, because the insert tube has a cylindrical structure and is made of a soft, easily deformable material, existing laser engraving equipment struggles to effectively and stably clamp and fix it during processing. This often results in uneven, unclear, or misaligned engraved graphics, severely impacting the quality and efficiency of the engraving. Utility Model Content

[0025] As described in the background section, the scale markings on endoscope insertion tubes are mostly processed using laser engraving. However, because the insertion tube has a cylindrical structure and is made of soft, easily deformable material, existing laser engraving equipment has difficulty in effectively and stably clamping and fixing it during the processing. This often results in problems such as uneven, unclear, and positional deviations in the engraved graphics, which seriously affect the quality of the engraving and work efficiency.

[0026] Based on this, please refer to Figures 1-5 The present invention provides a laser engraving device 100, which can effectively improve the aforementioned technical problems. Specifically, it can stably fix the pipe 200 and achieve annular engraving on the pipe 200, ensuring uniform engraving patterns and clear scales, thus improving the quality and efficiency of the engraving. The laser engraving device 100 will be described in detail below.

[0027] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the laser engraving equipment 100 provided in this embodiment. Figure 2 This is a partial structural diagram of the laser engraving equipment 100 provided in this embodiment, combined with... Figure 1 and Figure 2The laser engraving equipment 100 includes an engraving platform 10, a first support 21, a second support 22, a drive device 30, a rotating rod 40, and a laser emitter 50. The first support 21 and the second support 22 are both mounted on the engraving platform 10, with the second support 22 supporting the pipe 200. The drive device 30 is mounted on the engraving platform 10, and the drive device 30, the second support 22, and the first support 21 are arranged alternately. The two ends of the rotating rod 40 are respectively mounted on the first support 21 and the drive device 30, and the rotating rod 40 is used to pass through the pipe 200. The laser emitter 50 is mounted on the engraving platform 10 and is used to perform laser engraving on the pipe 200. The drive device 30 drives the rotating rod 40 to rotate relative to the first support 21 and the second support 22, thereby rotating the pipe 200.

[0028] As easily understood, by inserting the rotating rod 40 through the tube 200, the tube 200 can be subjected to force in a straight line, making it less prone to deformation and bending. Furthermore, with both ends of the rotating rod 40 respectively mounted on the driving device 30 and the first support 21, the driving device 30 drives the rotating rod 40 to rotate, achieving ring-shaped engraving on the tube 200. Simultaneously, the tube 200 is supported by the second support 22 during rotation, ensuring stability. Therefore, this laser engraving equipment 100 can stably fix the tube 200 and achieve ring-shaped engraving, thus ensuring uniform engraving patterns and clear scales, improving engraving quality and work efficiency.

[0029] It should be noted that, specifically in this embodiment, the tube 200 is an insertion tube, that is, the rotating rod 40 passes through the insertion tube and drives the insertion tube to rotate. The laser emitter 50 performs 360° circumferential engraving on the outer wall of the insertion tube, so that the doctor can observe the scale on the insertion tube from all angles during the operation of the endoscope, thereby improving surgical efficiency. Of course, in other embodiments, the tube 200 can also be other types of tubular structures. In other words, the laser engraving device 100 is not limited to engraving the endoscope tube 200.

[0030] Please refer to Figure 3 , Figure 3 This is an assembly diagram of the first support 21 and the rotating rod 40 provided in this embodiment, combined with... Figure 3 To facilitate the installation of the rotating rod 40, the first bracket 21 has an installation hole. The laser engraving equipment 100 also includes a fixed flange 61, which is located in the installation hole. One end of the rotating rod 40 passes through the fixed flange 61.

[0031] Understandably, the inner diameter of the flange hole of the fixed flange 61 needs to be slightly larger than the outer diameter of the rotating rod 40 so that the rotating rod 40 can rotate within the flange hole without easily wobbling, thus ensuring the stability of the rotation.

[0032] It should be noted that, in order to improve the smoothness of rotation of the rotating rod 40, a sliding element can also be provided inside the flange hole. Optionally, the sliding element can be a bearing or other sliding structure.

[0033] Furthermore, in order to improve the stability of the fixed flange 61, the laser engraving equipment 100 also includes a fastener 62, which is disposed on the first bracket 21 and is used to lock and fix the fixed flange 61 to the first bracket 21.

[0034] It should be noted that in this embodiment, the fastener 62 is a locking bolt, which is threadedly connected to the first bracket 21, and one end of the locking bolt is used to extend into the mounting hole of the first bracket 21 and threadedly connected to or abutting against the fixing flange 61. Of course, in other embodiments, the fastener 62 can also be a pin or other fastening structure.

[0035] Please continue to combine Figure 3 The laser engraving equipment 100 also includes a limiting ring 63, which is sleeved on the rotating rod 40 and located at the end of the fixed flange 61 near the second support 22. The limiting ring 63 is used to abut against the end face of the pipe 200. By setting the limiting ring 63, the pipe 200 can be separated from the fixed flange 61, and the friction between the pipe 200 and the fixed flange 61 can be offset to a certain extent, thereby protecting the end face of the pipe 200 and making it less prone to wear during rotation.

[0036] Combination Figure 2 In order to reduce the shaking of the pipe 200 during rotation and improve the stability and accuracy of the engraving process, in this embodiment, the laser engraving equipment 100 also includes a limiting structure 70, which is set on the second support 22 and is used for the pipe 200 to abut.

[0037] For details, please refer to Figure 4 , Figure 4 This is an assembly diagram of the second bracket 22 and the limiting structure 70 provided in this embodiment, combined with... Figure 4 The limiting structure 70 includes a fixing member 71 and a limiting rod 72. The fixing member 71 is movably disposed on the second bracket 22, and the limiting rod 72 is disposed on the fixing member 71 and is used to abut against the pipe 200.

[0038] Specifically in this embodiment, the fixing member 71 is threadedly connected to the second bracket 22. That is, the height of the limiting rod 72 can be adjusted by rotating the fixing member 71, thereby adapting to pipes 200 with different outer diameters.

[0039] In order to improve the smoothness of the pipe 200 during rotation and reduce rotational damage to the pipe 200, in this embodiment, the limiting structure 70 further includes a lubricating sleeve 73, which is sleeved on the limiting rod 72 and used to abut against the pipe 200.

[0040] Similarly, in order to improve the smoothness of the rotation of the pipe 200, the laser engraving equipment 100 also includes a lubricating pad 64, which is disposed on the second support 22 and is used to abut against the pipe 200.

[0041] It is easy to understand that by setting the lubrication sleeve 73 and the lubrication pad 64, the friction during the rotation of the pipe 200 can be reduced, ensuring that the pipe 200 can rotate stably, thereby improving the uniformity and clarity of the engraved pattern and enhancing the quality of the engraving.

[0042] Furthermore, the lubricating pad 64 has a groove 641, which facilitates the installation of the pipe 200 and further improves the rotational stability of the pipe 200.

[0043] Please continue to combine Figure 2 In order to improve the support stability of the pipe 200, there can be multiple second supports 22. Multiple second supports 22 are spaced apart along the length of the rotating rod 40 and are all located between the drive device 30 and the first support 21.

[0044] It should be noted that in this embodiment, the number of second supports 22 is specifically four, and each second support 22 is provided with a lubricating pad 64 and a limiting structure 70. Of course, in other embodiments, the number of second supports 22 can also be one, two, or three, etc.

[0045] Furthermore, to accommodate pipes 200 of different lengths and ensure the engraving effect, in this embodiment, the laser engraving equipment 100 also includes a first slide rail 81 and a second slide rail 82. The first slide rail 81 and the second slide rail 82 are spaced apart on the engraving platform 10 and both extend along the length direction of the rotating rod 40. The driving device 30 is slidably mounted on the first slide rail 81, and the second bracket 22 is slidably mounted on the second slide rail 82.

[0046] In other words, the drive device 30 can slide on the first slide rail 81 and the second bracket 22 can slide on the second slide rail 82 according to the length of the tube 200, so as to adjust the distance between the drive device 30, the second bracket 22 and the first bracket 21, thereby ensuring that tubes 200 of different lengths can be effectively clamped and fixed, and improving the engraving effect.

[0047] To improve stability during the sliding process, there can be multiple first slide rails 81 and multiple second slide rails 82. Multiple first slide rails 81 are spaced apart, and the driving device 30 is slidably mounted on multiple first slide rails 81 simultaneously. Similarly, multiple second slide rails 82 are spaced apart, and the second bracket 22 is slidably mounted on multiple second slide rails 82 simultaneously. For example, in this embodiment, there are two first slide rails 81 and two second slide rails 82. Of course, in other embodiments, the number of first slide rails 81 and second slide rails 82 can be one, three, or four, etc.

[0048] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the driving device 30 provided in this embodiment, combined with... Figure 2 and Figure 5 The drive device 30 includes a motor 31 and a clamping member 32. The motor 31 is mounted on the engraving platform 10 and connected to the clamping member 32. The clamping member 32 is connected to one end of the rotating rod 40. By setting the clamping member 32, the rotating rod 40 can be stably clamped and rotated, and the rotating rod 40 can be easily installed and removed.

[0049] Specifically, the clamping member 32 includes a mounting part 321 and a plurality of clamping blocks 322. The mounting part 321 is connected to the motor 31, and the mounting part 321 has a plurality of clamping slots. The plurality of clamping blocks 322 are respectively disposed in the plurality of clamping slots. The ends of the plurality of clamping slots that are close to each other are connected. One end of the rotating rod 40 is disposed at the connection of the plurality of clamping slots, and the plurality of clamping blocks 322 simultaneously abut against one end of the rotating rod 40 to clamp it.

[0050] In this embodiment, there are three clamping blocks 322 and three clamping slots, which are arranged in a ring with intervals. The included angle between any two adjacent clamping blocks 322 or clamping slots is 120°, which can improve the clamping stability of the rotating rod 40. Of course, in other embodiments, the number of clamping blocks 322 and clamping slots can also be two, four, or five, etc.

[0051] Furthermore, to facilitate the installation of the motor 31, the drive device 30 also includes a third bracket 33, which is disposed on the engraving platform 10, and the motor 31 is disposed on the third bracket 33. Specifically, in this embodiment, the third bracket 33 is slidably disposed on the first slide rail 81.

[0052] Please continue to combine Figure 1 The laser engraving equipment 100 also includes a moving mechanism 90, which is disposed on the engraving platform 10. The laser emitter 50 is disposed on the moving mechanism 90, and the moving mechanism 90 is used to drive the laser emitter 50 to move along the length direction of the rotating rod 40.

[0053] As is easy to understand, after the laser emitter 50 completes the engraving of one position on the tube 200, the moving mechanism 90 drives the laser emitter 50 to move to the next engraving position to continue the engraving operation, which can improve the engraving efficiency.

[0054] Furthermore, to improve the automation level of laser engraving and enhance its accuracy and efficiency, the laser engraving equipment 100 may also include a controller electrically connected to the moving mechanism 90 to control the moving distance of the laser emitter 50. Alternatively, the controller may also be electrically connected to the drive device 30 to control the rotation speed of the rotating rod 40.

[0055] In summary, the embodiments of this utility model provide a laser engraving device 100, which includes an engraving platform 10, a first support 21, a second support 22, a driving device 30, a rotating rod 40, and a laser emitter 50. The first support 21 and the second support 22 are both disposed on the engraving platform 10, and the second support 22 is used to support the tube 200. The driving device 30 is disposed on the engraving platform 10, and the driving device 30, the second support 22, and the first support 21 are arranged alternately. The two ends of the rotating rod 40 are respectively disposed on the first support 21 and the driving device 30, and the rotating rod 40 is used to pass through the tube 200. The laser emitter 50 is disposed on the engraving platform 10 and is used to perform laser engraving on the tube 200. The driving device 30 is used to drive the rotating rod 40 to rotate relative to the first support 21 and the second support 22, so as to drive the tube 200 to rotate. By inserting the rotating rod 40 through the tube 200, the tube 200 can be subjected to force in a straight line, making it less prone to deformation and bending. The two ends of the rotating rod 40 are respectively mounted on the driving device 30 and the first support 21. The driving device 30 drives the rotating rod 40 to rotate, achieving ring-shaped engraving on the tube 200. Simultaneously, the tube 200 is supported by the second support 22 during rotation, ensuring stability. Therefore, this laser engraving equipment 100 can stably fix the tube 200 and achieve ring-shaped engraving, thus ensuring uniform engraving patterns and clear scales, improving engraving quality and work efficiency.

[0056] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
