Description

Technical Field

[0001] The invention belongs to the technical field of laser beam processing, in particular to a device for double-sided laser marking of orthopedic instruments. Background Art

[0002] The double-sided laser marking device for orthopedic instruments is an automated processing equipment designed specifically for orthopedic instruments. It uses a laser beam to simultaneously mark two opposite or different surfaces of an object to improve production efficiency and marking accuracy.

[0003] In the prior art, the orthopedic instrument is placed on a supporting rectangular block, and then a high-power laser transmitter installed inside the device is started to generate a laser beam, which is focused through a lens system to form a very small and powerful laser beam. The moving path and marking depth of the laser are then adjusted through a precise control system to achieve double-sided marking of the orthopedic instrument.

[0004] There are still some problems in the actual application of the above scheme. When producing cylindrical orthopedic instruments, different sizes will be produced to meet the needs of different surgeries, and different sizes of supporting rectangular blocks are required to be used in the marking process of these orthopedic instruments of different sizes. Replacing the supporting rectangular blocks requires a series of operations such as disassembly, installation, and calibration. These steps will consume a lot of time, thereby reducing the overall marking efficiency. At the same time, after each replacement of the supporting rectangular blocks, recalibration and debugging are required to ensure the accuracy of marking. However, frequent replacement will increase the difficulty and error rate of calibration, thereby affecting the marking accuracy. In addition, the added adaptive clamping mechanism will generate friction with the surface of the orthopedic instrument during use, thereby causing scratches on the surface of the orthopedic instrument material, and scratches will damage the coating or treatment layer on the surface of the orthopedic instrument. These coatings or treatment layers often have specific functions, such as corrosion resistance, lubrication or biocompatibility.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figures 1 to 8 As shown, a device for double-sided laser marking of orthopedic instruments according to an embodiment of the present invention comprises a workbench 1, a marking device 2 is arranged on the upper part of the workbench 1, the marking device 2 comprises a first guide plate 201, the first guide plate 201 is fixedly connected to the upper surface of the workbench 1, a sliding column 202 is slidably connected to the upper part of the first guide plate 201, a laser lamp 203 is fixedly connected to the side of the sliding column 202, a lens 204 is fixedly connected to one end of the laser lamp 203, a positioning plate 205 is arranged on the side of the first guide plate 201, a supporting rectangular block 206 is threadedly connected to the top of the positioning plate 205, an adaptive clamping mechanism 3 is arranged on the top of the marking device 2, and the adaptive clamping mechanism 3 is used to adapt to the limiting work of cylindrical orthopedic instruments of different diameters;

[0037] The adaptive clamping mechanism 3 includes a sliding plate 314 that slides on the workbench 1, a bidirectional screw rod 318 is rotatably arranged in the middle of the sliding plate 314, a reciprocating plate 317 is threaded on the outer annular surface of the bidirectional screw rod 318, a support rod 401 is fixedly arranged on the side of the reciprocating plate 317, and an elastic cleaning cloth 402 is fixedly arranged on the end of the support rod 401 away from the reciprocating plate 317, and the reciprocating movement of the elastic cleaning cloth 402 can clean the marking area of ​​the medical device.

[0038] Specifically, when producing cylindrical orthopedic instruments, different sizes are produced to meet the needs of different surgeries, and different sizes of supporting rectangular blocks 206 are required to be used in the marking process of these orthopedic instruments of different sizes. Replacing the supporting rectangular blocks 206 requires a series of operations such as disassembly, installation, and calibration. These steps consume a lot of time, thereby reducing the overall marking efficiency. At the same time, after each replacement of the supporting rectangular block 206, recalibration and debugging are required to ensure the accuracy of marking. However, frequent replacement will increase the difficulty and error rate of calibration, thereby affecting the accuracy of marking.

[0039] Therefore, the present invention solves this problem by setting a corresponding structure. The present invention describes a device for double-sided laser marking of orthopedic instruments. When the staff places the cylindrical orthopedic instrument to be marked horizontally on the supporting rectangular block 206 along the direction of the laser lamp 203, the laser lamp 203 is started to generate a laser beam, and a very fine and powerful laser beam is formed by focusing the lens 204. The moving path and marking depth of the laser are adjusted through a precise control system to achieve double-sided marking of the cylindrical orthopedic instrument. However, during the working process, the dust on the surface of the cylindrical orthopedic instrument will cause The marking content is unclear, which affects the clarity of the mark. At this time, the rotation of the bidirectional screw 318 drives the two sets of reciprocating plates 317 to move synchronously toward the middle to achieve the positioning of the cylindrical orthopedic instrument. At this time, the elastic cleaning cloth 402 will be attached to the surface of the cylindrical orthopedic instrument. Secondly, the two sets of reciprocating plates 317 perform relative linear motion to drive the elastic cleaning cloth 402 to move in opposite directions, and then the elastic cleaning cloth 402 cleans the marking position of the cylindrical orthopedic instrument, so that the laser or mechanical marking equipment can act on the material surface more accurately, so that it can generate clearer and more accurate marks.

[0040] Embodiment 2

[0041] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0042] like Figure 3 As shown, the adaptive clamping mechanism 3 of this embodiment includes a fixed base plate 301 , a driving source 302 is fixedly arranged at the bottom of the fixed base plate 301 , an output shaft of the driving source 302 is fixedly connected to a rotating shaft 303 , and the rotating shaft 303 passes through and is rotatably connected to the middle of the fixed base plate 301 .

[0043] Specifically, when it is necessary to mark a cylindrical orthopedic instrument, the fixed base plate 301 is started to make its output shaft rotate clockwise, and at the same time, the rotating shaft 303 fixed to the output shaft of the fixed base plate 301 will be driven to rotate synchronously. Since the rotating shaft 303 passes through the fixed base plate 301, the fixed base plate 301 will not be driven to rotate when the rotating shaft 303 rotates.

[0044] like Figure 4 As shown, in this embodiment, a linkage rod 304 is fixedly connected to the outer ring surface of the rotating shaft 303, and a first fixed column 305 is fixedly connected to one end of the linkage rod 304 away from the rotating shaft 303. The outer ring surface of the first fixed column 305 is rotatably connected to a connecting rod 306.

[0045] Specifically, since the output shaft of the driving source 302 rotates clockwise and drives the rotating shaft 303 to rotate synchronously, the linkage rod 304 fixed on the outer ring surface of the rotating shaft 303 will rotate synchronously and drive the connecting rod 306 to approach the rotating shaft 303 through the first fixed column 305. Since connecting rods 306 are provided at both ends of the linkage rod 304, the two groups of connecting rods 306 will synchronously approach the rotating shaft 303 when the linkage rod 304 rotates.

[0046] like Figure 4 As shown, in this embodiment, a second fixed column 307 is provided at one end of the connecting rod 306 away from the first fixed column 305, and the connecting rod 306 is rotatably connected to the outer annular surface of the second fixed column 307. A reciprocating rod 308 is fixedly connected to the bottom of the second fixed column 307, and support columns 309 are fixedly connected to both ends of the reciprocating rod 308.

[0047] Specifically, when the connecting rod 306 is subjected to the pulling force from the linkage rod 304 through the first fixed column 305, it will drive the second fixed column 307 away from one end of the first fixed column 305 to move synchronously. At the same time, since the bottom of the second fixed column 307 is fixedly connected to the middle of the reciprocating rod 308, the reciprocating rod 308 will also move synchronously, and at the same time, it will drive the support columns 309 at the upper ends of the two ends to move simultaneously. At this time, the two sets of reciprocating rods 308 will drive the support columns 309 at both ends to move toward the direction of the rotating shaft 303.

[0048] like Figure 4 As shown, in this embodiment, a second guide plate 310 is disposed at the bottom of the reciprocating rod 308 , the reciprocating rod 308 is slidably connected to the outer surface of the second guide plate 310 , and the second guide plate 310 is fixedly connected to the upper part of the fixed bottom plate 301 .

[0049] Specifically, when the reciprocating rod 308 moves toward the rotating shaft 303, since the reciprocating rod 308 slides on the upper part of the second guide plate 310, and the second guide plate 310 is fixed on the upper part of the fixed base plate 301, the reciprocating rod 308 will move linearly along the guide of the second guide plate 310 when moving.

[0050] like Figure 4 and Figure 5 As shown, in this embodiment, the upper part of the middle part of the fixed base plate 301 is fixedly connected to a fixed disc 311, the rotating shaft 303 passes through the middle part of the fixed disc 311 and is rotatably connected, an annular groove 312 is provided on the outer ring surface of the fixed disc 311, and the lower part of the middle part of the linkage rod 304 is fixedly connected to a limiting column 313, and the limiting column 313 is slidably connected in the annular groove 312.

[0051] Specifically, when the rotating shaft 303 rotates clockwise, since the rotating shaft 303 passes through the middle of the fixed disk 311, the fixed disk 311 will not be driven to rotate when the rotating shaft 303 rotates. At the same time, since the limiting column 313 fixed at the lower part of the linkage rod 304 slides inside the annular groove 312, it can provide a guiding function when the linkage rod 304 rotates.

[0052] like Figure 5 and Figure 6 As shown, in this embodiment, the sliding plate 314 is fixedly connected to the top of the support column 309 , and a guide groove 315 is opened on the upper part of the fixed bottom plate 301 , and the sliding plate 314 is slidably connected in the guide groove 315 .

[0053] Specifically, since the support column 309 will pull the reciprocating rod 308 along the guide direction of the second guide plate 310 to move in the direction of the rotating axis 303 under the connection rod 306, the sliding plate 314 fixed on the top of the support column 309 will also move synchronously. At the same time, since the sliding plate 314 slides in the guide groove 315, the sliding plate 314 will also perform linear motion synchronously under the guidance of the guide groove 315.

[0054] like Figure 7 As shown, in this embodiment, a guide rod 316 is fixedly connected to the upper portion of the sliding plate 314 , a reciprocating plate 317 is slidably connected to the outer annular surface of the guide rod 316 , and a bidirectional screw rod 318 is rotatably connected to the middle portion of the sliding plate 314 .

[0055] Specifically, when the sliding plate 314 moves to the position where the cylindrical orthopedic medical device needs to be marked, the external motor whose output shaft is fixed to one end of the bidirectional screw 318 is started to drive the bidirectional screw 318 to rotate. At this time, the two groups of reciprocating plates 317 threadedly connected to the bidirectional screw 318 will move synchronously. At the same time, guided by the guide rod 316, the two groups of reciprocating plates 317 will move relative to each other, thereby achieving the effect of limiting the cylindrical medical device. At the same time, since the rotation of the bidirectional screw 318 drives the sliding plate 314 to move back and forth, it can achieve the effect of limiting different diameter sizes, thereby avoiding a series of operations such as disassembly, installation, and calibration of the supporting rectangular block 206, thereby improving the overall marking work efficiency.

[0056] like Figure 8 As shown, in this embodiment, a cleaning mechanism 4 for cleaning is arranged on the side of the adaptive clamping mechanism 3, and the cleaning mechanism 4 includes a piston cylinder 403, and a reciprocating spring 404 is fixedly connected inside the piston cylinder 403, and a telescopic column 405 is fixedly connected to one end of the reciprocating spring 404 away from the reciprocating moving plate 317, and a rotating ball 406 is hinged on one end of the telescopic column 405 away from the reciprocating spring 404.

[0057] Specifically, when the two groups of reciprocating plates 317 perform relative linear motion, the rotating ball 406 will first contact the outer annular surface of the cylindrical medical device. However, since the reciprocating plates 317 are still performing relative motion, the reciprocating spring 404 will be compressed by the telescopic column 405 and move along the guide direction of the piston cylinder 403 toward the reciprocating plate 317. Moreover, since multiple groups of rotating balls 406, telescopic columns 405, reciprocating springs 404 and piston cylinders 403 are arranged on the opposite side of the lower part of the two groups of reciprocating plates 317, the two groups of reciprocating plates 317 can adapt to the outer arc surface of the cylindrical orthopedic device when they move toward each other, thereby achieving a better positioning effect.

[0058] like Figure 8 As shown, in this embodiment, the support rod 401 is fixedly connected to the side of the reciprocating plate 317 , and the elastic cleaning cloth 402 is fixedly connected to one end of the support rod 401 away from the reciprocating plate 317 .

[0059] Specifically, when the two groups of reciprocating plates 317 move to the appropriate positions, since the height of the support rod 401 is consistent with the height from the piston cylinder 403 to the rotating ball 406, when the multiple groups of telescopic columns 405 are squeezed and move toward the reciprocating plate 317, the elastic cleaning cloth 402 will also be close to the surface of the cylindrical orthopedic instrument, and since the support rod 401 and the elastic cleaning cloth 402 are arranged on the opposite side of the two groups of vertical reciprocating plates 317, the marking part of the cylindrical orthopedic instrument will be wrapped, and at the same time, starting the driving source 302 to rotate counterclockwise will cause the reciprocating rod 308 to move along the guide direction of the second guide plate 310 away from the rotating shaft 303, and at the same time, it will pass through The movement of the support column 309 pulls the two sets of sliding plates 314 in the vertical direction to move toward each other, and drives the two sets of reciprocating plates 317 in the vertical direction to move toward each other, so that the two sets of elastic cleaning cloths 402 in the vertical direction move toward each other, thereby achieving the effect of cleaning the marking area, allowing the laser or mechanical marking equipment to act more accurately on the material surface and generate clearer and more accurate markings. At the same time, since the rotating ball 406 is hinged to the telescopic column 405, when the two sets of reciprocating plates 317 move toward each other along the guide groove 315, the rotating ball 406 will roll, thereby reducing the wear on the surface of the cylindrical orthopedic instrument and increasing the service life of the cylindrical orthopedic instrument.

[0060] Working principle: when it is necessary to mark a cylindrical orthopedic instrument, the fixed base plate 301 is started to make its output shaft rotate clockwise, and at the same time, the rotating shaft 303 fixed to the output shaft of the fixed base plate 301 will be driven to rotate synchronously. Since the rotating shaft 303 passes through the fixed base plate 301, the fixed base plate 301 will not be driven to rotate when the rotating shaft 303 rotates.

[0061] Since the output shaft of the driving source 302 rotates clockwise and drives the rotating shaft 303 to rotate synchronously, the linkage rod 304 fixed on the outer ring surface of the rotating shaft 303 will rotate synchronously at this time, and drive the connecting rod 306 to approach the rotating shaft 303 through the first fixed column 305. Since connecting rods 306 are provided at both ends of the linkage rod 304, the two groups of connecting rods 306 will synchronously approach the rotating shaft 303 when the linkage rod 304 rotates.

[0062] When the connecting rod 306 is subjected to the pulling force from the linkage rod 304 through the first fixed column 305, it will drive the second fixed column 307 away from one end of the first fixed column 305 to move synchronously. At the same time, since the bottom of the second fixed column 307 is fixedly connected to the middle of the reciprocating rod 308, the reciprocating rod 308 will also move synchronously, and at the same time, it will drive the support columns 309 at the upper ends of the two ends to move simultaneously. At this time, the two sets of reciprocating rods 308 will drive the support columns 309 at both ends to move toward the direction of the rotating shaft 303.

[0063] When the reciprocating rod 308 moves toward the rotating shaft 303, since the reciprocating rod 308 slides on the upper part of the second guide plate 310, and the second guide plate 310 is fixed on the upper part of the fixed base plate 301, the reciprocating rod 308 will move linearly along the guide of the second guide plate 310 when moving.

[0064] When the rotating shaft 303 rotates clockwise, since the rotating shaft 303 passes through the middle of the fixed disk 311, the fixed disk 311 will not be driven to rotate when the rotating shaft 303 rotates. At the same time, since the limiting column 313 fixed at the lower part of the linkage rod 304 slides inside the annular groove 312, it can provide a guiding function when the linkage rod 304 rotates.

[0065] Since the support column 309 will pull the reciprocating rod 308 along the guide direction of the second guide plate 310 to move in the direction of the rotating axis 303 under the connection rod 306, the sliding plate 314 fixed on the top of the support column 309 will also move synchronously. At the same time, since the sliding plate 314 slides in the guide groove 315, the sliding plate 314 will also move linearly synchronously under the guidance of the guide groove 315.

[0066] When the sliding plate 314 moves to the position where the cylindrical orthopedic medical device needs to be marked, the external motor whose output shaft is fixed to one end of the bidirectional screw 318 is started to drive the bidirectional screw 318 to rotate. At this time, the two groups of reciprocating plates 317 threadedly connected to the bidirectional screw 318 will move synchronously. At the same time, guided by the guide rod 316, the two groups of reciprocating plates 317 will move relative to each other, thereby achieving the effect of limiting the cylindrical medical device. At the same time, since the rotation of the bidirectional screw 318 drives the sliding plate 314 to move back and forth, it can achieve the effect of limiting different diameter sizes, thereby avoiding a series of operations such as disassembly, installation, and calibration of the supporting rectangular block 206, thereby improving the overall marking work efficiency.

[0067] When the two groups of reciprocating plates 317 perform relative linear motion, the rotating ball 406 will first contact the outer annular surface of the cylindrical medical device. However, since the reciprocating plates 317 are still performing relative motion, the reciprocating spring 404 will be compressed by the telescopic column 405 and move along the guide direction of the piston cylinder 403 toward the reciprocating plate 317. Moreover, since multiple groups of rotating balls 406, telescopic columns 405, reciprocating springs 404 and piston cylinders 403 are arranged on the opposite side of the lower part of the two groups of reciprocating plates 317, the two groups of reciprocating plates 317 can adapt to the outer arc surface of the cylindrical orthopedic device when they move toward each other, thereby achieving a better positioning effect.

[0068] When the two groups of reciprocating plates 317 move to the appropriate position, since the height of the support rod 401 is consistent with the height from the piston cylinder 403 to the rotating ball 406, when the multiple groups of telescopic columns 405 are squeezed and move toward the reciprocating plate 317, the elastic cleaning cloth 402 will also be close to the surface of the cylindrical orthopedic instrument. Since the support rod 401 and the elastic cleaning cloth 402 are arranged on the opposite side of the two groups of vertical reciprocating plates 317, the marking part of the cylindrical orthopedic instrument will be wrapped. At the same time, starting the driving source 302 to rotate counterclockwise will cause the reciprocating rod 308 to move along the guide direction of the second guide plate 310 away from the rotating shaft 303, and at the same time, it will pass through the support rod 401. The movement of the column 309 pulls the two sets of sliding plates 314 in the vertical direction to move toward each other, and drives the two sets of reciprocating plates 317 in the vertical direction to move toward each other, so that the two sets of elastic cleaning cloths 402 in the vertical direction move toward each other, thereby achieving the effect of cleaning the marking area, allowing the laser or mechanical marking equipment to act more accurately on the material surface and generate clearer and more accurate markings. At the same time, since the rotating ball 406 is hinged to the telescopic column 405, when the two sets of reciprocating plates 317 move toward each other along the guide groove 315, the rotating ball 406 will roll, thereby reducing the wear on the surface of the cylindrical orthopedic instrument and increasing the service life of the cylindrical orthopedic instrument.
