[0002] With the development of technology, the standards in the medical industry have been improved synchronously. Among them, medical blades are one of the necessary tools in the treatment process. Therefore, the precision of the production of medical blades greatly affects the effect of the treatment operation. In the traditional cutting device for the production of medical blades, due to the small size of the blade material, the cutting speed cannot be too fast to avoid the consequences of product deformation and tooth rack defects during the processing, and employees need to reach a certain level of proficiency to operate it skillfully. In addition, the cutting time is long and the precision is low. During the cutting process, dust is easily generated, polluting the environment and endangering the health of the operators. Summary of the Utility Model

[0003] In order to improve the problem that the traditional blade cutting device requires a certain level of proficiency of personnel, thus increasing the usage threshold, and with the increase in the number of cuts, the cutting efficiency and cutting precision decline, and dust is easily generated, this application provides a laser cutting machine for medical blades.

[0004] The laser cutting machine for medical blades provided by this application adopts the following technical solutions:

[0005] A laser cutting machine for medical blades includes a main housing. A cutting cavity for installing cutting equipment is opened inside the main housing, and a cutting mechanism is arranged on one side of the cutting cavity.

[0006] The cutting mechanism includes a Z-axis moving mechanism fixedly arranged on one side of the bottom of the cutting cavity. The surface of the moving shaft of the Z-axis moving mechanism is connected with an X-axis moving mechanism. The surface of the moving shaft of the X-axis moving mechanism is connected with a laser connecting piece, and a laser vibration lens is fixedly connected to the end of the laser connecting piece far away from the Z-axis moving mechanism.

[0007] A cutting groove is opened at one end of the bottom of the cutting cavity far away from the Z-axis moving mechanism. An air extraction mechanism is arranged on the side surface of the cutting groove, and a bottom groove is opened at the bottom of the cutting groove. The adjustment mechanism includes a lead screw rotatably arranged in the bottom groove. A placing seat is connected to the surface of the lead screw, and a plurality of die slots are opened at the top of the placing seat.

[0008] By adopting the above technical solutions, the Z-axis moving mechanism and the X-axis moving mechanism enable the laser vibration lens to have the functions of lifting and lateral movement. At the same time, the placing seat moves longitudinally through the lead screw, forming a three-direction linkage movement, so as to precisely cut the blades on the surface of the placing seat.

[0009] Preferably, the cutting mechanism further includes a first connecting block threadedly connected to the moving shaft of the Z-axis moving mechanism. One side of the first connecting block away from the Z-axis moving mechanism is fixedly connected to the surface of the housing of the X-axis moving mechanism. A second connecting block is threadedly connected to the moving shaft of the X-axis moving mechanism. One side of the second connecting block away from the X-axis moving mechanism is fixedly connected to the top of the laser connecting piece.

[0010] By adopting the above technical solution, the Z-axis moving mechanism drives the first connecting block to make the entire X-axis moving mechanism reciprocate in the Z-axis direction. At the same time, the X-axis moving mechanism drives the second connecting block to reciprocate along the X-axis direction, enabling the laser connecting piece to have simultaneous X and Y-axis linkage movement.

[0011] Preferably, a connecting ring is disposed around the top surface of the laser beam expander head. The top of the connecting ring is fixedly connected to a refraction housing. A lens knob is rotatably disposed on the top of the refraction housing.

[0012] By adopting the above technical solution, rotating the lens knob controls the angle of the lens in the refraction housing, so that the laser horizontally emitted by the laser welding head is refracted by 90° to achieve the purpose of turning.

[0013] Preferably, the adjustment mechanism further includes folding covers fixedly provided on both sides of the placement seat. One end of each of the two folding covers away from the placement seat is fixedly connected to both ends of the cutting groove respectively.

[0014] By adopting the above technical solution, the folding covers are stretched and deformed while moving with the placement seat, and completely cover the lead screw, preventing the flying chips generated by cutting from falling into the lead screw and causing instrument wear.

[0015] Preferably, a limiting block is fixedly provided around the upper end surface of the placement seat around the periphery of a plurality of mold grooves.

[0016] By adopting the above technical solution, the limiting blocks surround the mold grooves to clamp and fix the inserted blades, providing a good cutting environment.

[0017] Preferably, a servo motor is fixedly provided on the outer surface of the main housing on the side aligned with the lead screw. The output end of the servo motor penetrates the main housing and is fixedly connected to one end of the lead screw.

[0018] By adopting the above technical solution, the output shaft of the servo motor rotates to drive the lead screw to rotate, providing a power source for the movement of the placement seat.

[0019] Preferably, a heat dissipation window is opened on the outer surface of the main housing on one side above the servo motor, and a feeding window is opened on the outer surface of the main housing adjacent to the heat dissipation window.

[0020] By adopting the above technical solution, the material is fed into the placement seat through the feeding window for cutting operations, and at the same time, the heat generated by cutting is discharged to the outside through the heat dissipation window.

[0021] Preferably, a display screen is embedded and installed on one side of the outer surface of the main housing located at the feeding window. A plurality of supporting feet are fixedly provided on the lower end surface of the main housing, and rollers are rotatably arranged between the plurality of supporting feet on the lower end surface of the main housing.

[0022] By adopting the above technical solution, the supporting feet are adjusted to abut against the ground so that the main housing is supported and fixed. When the supporting feet contract and move away from the ground, the operator can push the main housing, and the main housing can be moved through the rollers. At the same time, the display screen can provide real-time feedback on the coordinate parameters of the cutting mechanism and the adjustment mechanism.

[0023] To sum up, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The coordinate data of the cutting mechanism is fed back on the display screen by using the computer control system, and through the debugging of the operator, the multi-axis connection of the Z-axis moving mechanism, the X-axis moving mechanism and the lead screw is formed, so that the coordinates of the laser vibration lens and the placement seat are aligned for cutting operation. The control system performs cutting according to the preset pattern, which reduces the operation threshold of the operator and has the characteristics of high precision and high efficiency;

[0025] 2. The bottom groove is covered by the folding cover to prevent the dust generated by cutting from contacting the lead screw and causing wear. And the generated dust is sucked by the air extraction mechanism and discharged to the outside, which maintains a good cutting environment and prevents potential safety hazards for the operator.

[0035] The embodiment of this application discloses a medical blade laser cutting machine.

[0036] Embodiment 1

[0037] Referring to Figure 1 , 4 , a medical blade laser cutting machine includes a main housing 1. A cutting cavity 2 is opened inside the main housing 1. A cutting groove 3 is opened inward on one side of the bottom surface of the cutting cavity 2 in the main housing 1. And a bottom groove 10 is further opened in the middle of the bottom surface of the cutting groove 3. A heat dissipation window 8 is opened on one side of the outer surface of the main housing 1. And a plurality of holes are opened on the surface of the heat dissipation window 8. The holes penetrate through the main housing 1 and communicate with the cutting cavity 2. A feed window 11 is opened on one side of the outer surface of the main housing 1 adjacent to the heat dissipation window 8. The feed window 11 penetrates through the main housing 1 and communicates with the cutting cavity 2. And the opening of the feed window 11 is aligned with the cutting groove 3. A display screen 9 is fixedly arranged on one side of the outer surface of the main housing 1 close to the feed window 11. The display screen 9 is embedded and fixed on the outer wall surface of the main housing 1. And the display screen 9 is configured with accessories such as operation buttons and a keyboard.

[0038] It should be noted that a computer operating system, an electrical supply system, and a terminal of the display screen 9 and other structures are installed inside the main housing 1 below the cutting cavity 2. And the operation buttons and accessories such as the keyboard configured on the display screen 9 are all docked with the terminal. Since the structures such as the computer operating system, the electrical supply system, and the terminal configured on the display screen 9 are all prior arts, their structural principles will not be elaborated in detail.

[0039] Through the above settings, the cutting cavity 2, the cutting groove 3, and the bottom groove 10 opened in the main housing 1 reserve space for the subsequent installation of the cutting mechanism 4 and the adjustment mechanism 5. At the same time, the heat generated by the welding of the cutting mechanism 4 is discharged to the outside through the heat dissipation window 8. Personnel control the cutting mechanism 4 and the adjustment mechanism 5 by observing the display screen 9 and debugging the configured keyboard and buttons.

[0040] Referring to Figure 2 , 3, the cutting mechanism 4 includes a Z-axis moving mechanism 41 fixed to the main housing 1 at one side of the bottom of the cutting cavity 2 by screws. A connecting block 42 is threadedly connected to the surface of the rotating shaft of the Z-axis moving mechanism 41, and the other side of the connecting block 42 relative to the housing of the Z-axis moving mechanism 41 is fixedly welded to the housing of the X-axis moving mechanism 43. A connecting block 44 is threadedly connected to the surface of the rotating shaft of the X-axis moving mechanism 43, and the other side of the connecting block 44 relative to the housing of the X-axis moving mechanism 43 is fixed to the top of the laser connecting member 45 by screws.

[0041] It should be noted that both the motor ends of the Z-axis moving mechanism 41 and the X-axis moving mechanism 43 are docked with the electrical supply system, and a laser generator for emitting laser is provided at the access end of the laser connecting member 45.

[0042] Through the above settings, the rotating shaft of the Z-axis moving mechanism 41 rotates to make the connecting block 42 move up and down along the rotating shaft in the Z-axis direction. As the connecting block 42 moves, it drives the housing of the X-axis moving mechanism 43 to move up and down synchronously. At the same time, the rotating shaft of the X-axis moving mechanism 43 rotates to make the connecting block 44 move in the X-axis direction along the rotating shaft. As the connecting block 44 moves, it drives the laser connecting member 45 to move synchronously in translation, so that the laser connecting member 45 has the function of moving flexibly in both the X and Z axes.

[0043] Refer to Figure 2 、 3 , an output hole is opened at one end of the laser connecting member 45 away from the Z-axis moving mechanism 41, and a laser vibration lens 46 is fixedly connected at the output hole. The laser exit of the laser vibration lens 46 faces vertically downward, and one side of the laser vibration lens 46 is set as an inclined surface, and the inclined surface is communicated with the laser chamber inside the laser vibration lens 46. A connecting ring 47 is fixedly glued to the inclined surface of the laser vibration lens 46. The connecting ring 47 is made of rubber material. The other end of the connecting ring 47 away from the laser vibration lens 46 is fixedly glued to a refraction housing 48. An adjustable lens is provided inside the refraction housing 48, and a lens knob 49 is rotatably provided at the top of the refraction housing 48. The rotating end of the lens knob 49 movably penetrates through the refraction housing 48 and is fixedly connected to the outer frame of the lens.

[0044] Through the above settings, the laser connecting member 45 transmits the laser and horizontally inputs it into the laser vibration lens 46. Then the laser passes through the inclined surface of the laser vibration lens 46 and passes through the connecting ring 47 and enters the refraction housing 48, so as to be refracted by the lens inside the refraction housing 48, forming a 90° turn, and then entering the laser vibration lens 46 again and exiting from the laser exit at the bottom of the laser vibration lens 46 to the outside. At the same time, the operator can rotate the lens knob 49 to control the angle of the lens inside the refraction housing 48, so as to control the refraction angle of the laser.

[0045] Refer to Figure 1 、 2, 4. The adjustment mechanism 5 includes lead screws 51 rotatably connected to both ends inside the bottom groove 10. At the same time, a servo motor 52 is fixedly installed on the outside of the main housing 1 at the bottom of the heat dissipation window 8. The output shaft of the servo motor 52 movably penetrates through the main housing 1 and is fixedly connected to one end of the lead screw 51. A placement seat 53 is threadedly connected to the surface of the lead screw 51. The placement seat 53 is integrally T-shaped, and a plurality of mold grooves 56 are formed on the top surface of the placement seat 53 (the shape of the mold grooves 56 depends on the shape of the cutting blade, and the number is at least six). Four limiting blocks 55 are fixedly arranged around the plurality of mold grooves 56 on the top surface of the placement seat 53, and the four limiting blocks 55 surrounding each mold groove 56 are in a group. Telescopic and foldable folding covers 54 are fixedly arranged on both sides of the outer surface of the placement seat 53, and the other ends of the two folding covers 54 relative to the placement seat 53 are fixedly connected to the inner walls on both sides of the cutting groove 3.

[0046] It should be noted that the limiting blocks 55 have a certain magnetic force to magnetically fix the blades. An air extraction mechanism 6 is fixedly installed on the inner wall of the cutting groove 3 on one side of the placement seat 53 to collect and discharge the flying chips generated during cutting, preventing the flying chips from floating and affecting the device and personnel. And the air extraction mechanism 6 is also docked with the electrical supply system and the computer operating system.

[0047] Through the above settings, the output shaft of the servo motor 52 drives the lead screw 51 to rotate to provide a power source, so that the placement seat 53 translates along the surface of the lead screw 51. At the same time, as the placement seat 53 moves, the two folding covers 54 are respectively stretched and contracted, and the two folding covers 54 completely cover the lead screw 51, thereby preventing the debris generated by welding from falling onto the surface of the lead screw 51 and causing damage. At the same time, a plurality of materials fed in through the feeding window 11 are respectively fixed in multiple groups of limiting blocks 55, and the main waste generated by welding falls downward into the mold grooves 56 for collection.

[0048] Refer to Figure 1 , 2 , a plurality of feet 7 are fixedly installed on the bottom surface of the main housing 1. The rod parts of the plurality of feet 7 are all provided with telescopic rods. At the same time, a plurality of rollers 12 are installed on the bottom surface of the main housing 1 between the plurality of feet 7 in an interspersed and rolling manner. The number of feet 7 and the number of rollers 12 are normally set to 4, and the number is increased according to the size of the device.

[0049] Through the above settings, when the operator adjusts the telescopic rods of the feet 7 to extend and abut against the ground, the main housing 1 is supported and fixed. When the operator adjusts the telescopic rods of the feet 7 to contract, the main housing 1 is pushed, and the main housing 1 transmits the thrust to the rollers 12 to realize movement.

[0050] Among them, the Z-axis moving mechanism 41, X-axis moving mechanism 43, laser galvanometer head 46, servo motor 52, and air extraction mechanism 6 and other structures of this device are all existing technologies, and their structural principles will not be elaborated in detail.

[0051] The implementation principle of a medical blade laser cutting machine according to an embodiment of this application is as follows: When using this device, first place multiple blades to be cut through the feeding window 11 into multiple groups of limit blocks 55 on the surface of the placement seat 53 for clamping and fixing;

[0052] The operator manipulates the keyboard for debugging according to the coordinate data of the laser galvanometer head 46 fed back by the display screen 9. First, the Z-axis moving mechanism 41 receives a signal to rotate the internal rotating shaft, driving the connecting block one 42 to move up and down along the Z-axis. As the connecting block one 42 moves, the entire X-axis moving mechanism 43 moves synchronously. Then, the X-axis moving mechanism 43 receives a signal to rotate the internal rotating shaft, driving the connecting block two 44 to move horizontally along the X-axis. At this time, the connecting block two 44 is driven by the X-axis moving mechanism 43 and has both lifting and horizontal movements, driving the laser connecting piece 45 to move accordingly. Finally, the laser connecting piece 45 drives the laser galvanometer head 46 to move directly above the placement seat 53, and the laser galvanometer head 46 descends to the safe welding distance;

[0053] Then the computer system terminal sends a signal to control the laser generator to emit laser. The laser enters the laser galvanometer head 46 through the laser connecting piece 45, then horizontally enters the refraction housing 48 and refracts with the refraction mirror, completing a 90° turn and shooting downward into the laser galvanometer head 46 again. Finally, it is emitted from the laser port at the bottom of the laser galvanometer head 46 to the surface of the blade. Subsequently, the computer system synchronously sends signals to the Z-axis moving mechanism 41, X-axis moving mechanism 43, and servo motor 52 according to the blade pattern. The servo motor 52 drives the lead screw 51 to rotate, causing the placement seat 53 to move longitudinally. In cooperation with the adjustments of the Z-axis moving mechanism 41 and X-axis moving mechanism 43 in the Z and X axis directions of the laser galvanometer head 46, the laser galvanometer head 46 cuts the blade according to the pattern.

[0054] At the same time, during the welding process, by turning on the operation switch below the display screen 9, the air extraction mechanism 6 is controlled to start, sucking the flying debris generated during the cutting process and discharging it into the storage mechanism, ensuring the environment inside the cutting cavity 2 and extending the service life of the device.

[0055] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
