Description

Technical Field

[0001] The present invention relates to the technical field of dental implant production, and in particular to an intelligent production device and method for dental implants. Background Art

[0002] With the advancement of oral medicine technology, dental implants, as core components for restoring missing teeth, have placed stringent requirements on their processing accuracy, surface integrity, and biocompatibility. Titanium alloys and zirconium-based materials have become the mainstream materials for implants due to their excellent mechanical properties and biocompatibility. However, their high hardness and low thermal conductivity make traditional mechanical processing face problems such as rapid tool wear and large heat-affected zones. Plasma cutting technology, with its high-energy beam non-contact processing characteristics, has gradually been introduced into the field of implant precision forming, but there are still significant technical bottlenecks in actual application:

[0003] First, there's a lack of dynamic process parameter matching. Traditional plasma cutting uses fixed movement speeds and gas flow rates, but the thickness of the cut section constantly changes due to the irregular shapes of implants. For example, when cutting the gradient from the neck to the root of an implant, constant parameters can easily lead to overburning in thin areas or residual slag in thick areas, requiring frequent manual intervention and adjustments, severely limiting the efficiency of automated production.

[0004] Second, the gas environment is controlled in a crude manner. The mixing ratio of nitrogen and argon directly affects the stability of the plasma arc and the degree of oxidation at the cut. Existing equipment often uses a preset gas supply ratio, which cannot be dynamically optimized according to the needs of the cutting stage. Especially in titanium alloy cutting, initial slag removal requires a high nitrogen flow rate to impact the molten pool, while later stages require high argon concentrations to suppress the formation of a high-temperature oxide layer. A fixed ratio makes it difficult to achieve both phased process goals. Therefore, we propose an intelligent production device and method for dental implants to address this problem.

[0021] The present invention also provides an intelligent production method for dental implants, which is applied to the above-mentioned intelligent production equipment for dental implants and comprises the following steps:

[0022] S1: The dental implant raw material bar is passed through the through hole and the fixing cylinder of the fixing frame, and the first electric push rod is started to drive the pressure sensor, the push plate and the driving rack to move horizontally, and the connecting shaft is driven to rotate by meshing with the driving gear. The connecting shaft drives the turntable to rotate by meshing with the driving gear and the driven gear ring. The turntable drives the multiple clamping arms to approach each other through the cooperation of multiple guide grooves and corresponding connecting columns, so that the multiple clamping arms abut against the outer side of the raw material bar to achieve clamping. When the pressure value monitored by the pressure sensor reaches a preset value, the clamping force of the clamping arm on the raw material bar reaches a preset value. At this time, the controller controls the first electric push rod to stop feeding and complete the clamping;

[0023] S2: Start the driving motor to drive the screw to rotate. The screw cooperates with the thread of the moving seat and drives the moving seat to move horizontally along the guide rail under the guidance of the guide rail, and drives the laser rangefinder and plasma emitter to move horizontally. At the same time, the linkage shaft moves with the moving seat. The fixed rack drives the linkage shaft to rotate by meshing with the transmission gear. The linkage shaft drives the rotating frame to rotate and drives the counterweight plate to perform circular motion. The counterweight plate slides outward along the vertical rod under the action of centrifugal force, driving the movable pulley away from the rotating frame, thereby causing the other end of the connecting rope to pull the linkage plate closer to the linkage shaft and compress the connecting spring. The linkage plate moves through the positioning shaft. The side plate is driven to move horizontally. The side plate drives the first valve core to move horizontally through the connecting rod, so that the upper and lower ends of the through hole of the first valve core are connected with the air inlet cylinder and the three-way pipe respectively, so that the gas in the nitrogen compression storage tank and the argon compression storage tank enters the three-way pipe through the second regulating valve and the third regulating valve respectively, and then is introduced into the air inlet cylinder through the first regulating valve, and then introduced into the spiral groove of the jet cylinder through the air inlet pipe and is ejected downward in a spiral around the plasma emitter under the guidance of the spiral strip, so that the argon and nitrogen form a high-speed vortex, accelerate the mixing of nitrogen and argon, and in the subsequent plasma cutting process, the slag is quickly thrown away from the cutting seam by the centrifugal force of the vortex;

[0024] S3: Start the plasma emitter and emit high-speed plasma to cut the raw material bar that has been turned. At the same time, the laser rangefinder measures the surface distance between the moving plate and the bar, and controls the first electric push rod to drive the lifting plate to move up and down in real time through the controller, so that the plasma emitter and the top of the raw material bar maintain a basically constant distance to achieve cutting. At the same time, as the output end of the first electric push rod shrinks, the cross-sectional thickness of the cut raw material bar increases, and the controller synchronously controls the output speed of the drive motor to decrease, thereby reducing the moving speed of the plasma emitter to ensure complete cutting of the thicker area. At the same time, the speed of the linkage shaft decreases accordingly, which reduces the centrifugal force on the counterweight plate, so that the linkage plate and the first valve core are reset to the right under the action of the connecting spring and the compression spring respectively, thereby increasing the conduction area between the through hole and the air intake cylinder and the three-way pipe, thereby making The flow rates of nitrogen and argon are increased, thereby improving the slag removal ability and anti-oxidation effect. As the output end of the first electric push rod is applied, the cross-sectional thickness of the raw material bar being cut decreases, and the controller synchronously controls the output speed of the drive motor to increase, so that the flow rates of nitrogen and argon are gradually restored. At the same time, the linkage shaft drives the adjusting screw to rotate at a reduced speed through the small pulley, the synchronous belt and the large pulley. The adjusting screw drives the connecting plate to move to the right through the thread cooperation with the drive plate, thereby driving the second valve core and the third valve core to move to the right synchronously, so that the connecting cross-sectional area between the three-way pipe and the nitrogen inlet pipe is gradually reduced, and the connecting area between the three-way pipe and the argon inlet pipe is gradually increased. That is, in the early stage of cutting, the nitrogen ratio is large, which enhances the slag removal ability. In the middle stage of cutting, the nitrogen ratio is reduced and the argon ratio is increased, thereby suppressing oxidation. In the late stage of cutting, the argon ratio is further increased, thereby preventing terminal oxidation.

[0025] S4: The collection frame collects the cut dental implant metal sleeve, controls the plasma emitter and the drive motor to stop running, and controls the output end of the first electric push rod to retract, thereby driving the clamping arm to move in the reverse direction and release the clamping.

[0026] Compared with the prior art, the present invention provides an intelligent production device and method for dental implants, which has the following beneficial effects:

[0027] (1) The integrated pressure sensor and closed-loop control system realizes the intelligent clamping of dental implant raw material rods. During the clamping process, the system monitors the mechanical state of the clamping arm in real time and dynamically adjusts the clamping force to the preset threshold, which not only ensures the stable fixation of the raw material rod during processing, but also avoids damage or deformation of the material surface due to excessive clamping force. This adaptive clamping mechanism significantly improves processing accuracy and equipment reliability.

[0028] (2) By linking the drive motor speed and the plasma emitter movement speed, the system can automatically adjust the cutting parameters according to the thickness change of the cutting section. When the processing thickness increases, the plasma emitter movement speed is reduced and the gas flow is increased to ensure sufficient cutting and slag removal of the thick area; when the thickness decreases, the reverse adjustment is made to maintain efficiency. This dynamic balance design effectively solves the problem of overcutting or undercutting caused by uneven thickness in traditional cutting, ensuring the consistency and smoothness of the cutting surface;

[0029] (3) A mechanical feedback structure that links centrifugal force with the gas valve core can autonomously adjust the mixing ratio of nitrogen and argon. In the early stage of cutting, the nitrogen ratio is prioritized to enhance the slag removal capability. In the middle stage, the argon ratio is gradually increased to inhibit the oxidation reaction. In the later stage, the argon ratio is further optimized to prevent terminal oxidation. This timed gas ratio strategy takes into account both cutting efficiency and the chemical stability of the material surface, and is particularly suitable for the high-quality processing requirements of biocompatible metals such as titanium alloys.

[0030] (4) Through the coordinated design of spiral grooves and spiral strips, nitrogen and argon form a high-speed vortex in the jet tube. The strong turbulence effect generated by the spiral airflow significantly accelerates the collision and mixing between gas molecules, ensuring that nitrogen and argon are evenly distributed within a very short distance. The high-speed vortex of the mixed gas forms a dynamic air film barrier during the plasma cutting process. On the one hand, it enhances the stability and energy density concentration of the plasma arc. On the other hand, the molten metal slag is quickly thrown away along the tangent direction of the cut through the centrifugal force, effectively avoiding the secondary attachment of the slag or clogging of the cut. This design not only improves the finish and dimensional accuracy of the cutting surface, but also greatly reduces the complexity of the subsequent cleaning process. It is especially suitable for the clean cutting needs of highly active metals such as titanium alloys.

[0031] (5) By integrating a laser rangefinder and a lifting control module, the system achieves real-time dynamic calibration of the distance between the plasma emitter and the raw material bar. During the processing, it automatically compensates for distance fluctuations caused by material removal or thermal deformation, maintains a constant plasma action distance, greatly reduces the need for manual intervention, and significantly improves the efficiency and yield rate of mass production of dental implants, while reducing energy and gas consumption.

[0067] The present invention also provides an intelligent production method for dental implants, which is applied to the above-mentioned intelligent production equipment for dental implants and comprises the following steps:

[0068] S1: The dental implant raw material bar is passed through the through hole and the fixing cylinder 201 of the fixing frame 1, and the first electric push rod 401 is started to drive the pressure sensor 808, the push plate 806 and the driving rack 805 to move horizontally, and the connecting shaft 803 is driven to rotate by engaging with the driving gear 804. The connecting shaft 803 drives the turntable 202 to rotate through the engagement of the active gear 802 and the driven gear ring 801. The turntable 202 drives the multiple clamping arms 204 to approach each other through the cooperation of the multiple guide grooves 203 and the corresponding connecting columns 205, so that the multiple clamping arms 204 abut against the outer side of the raw material bar to achieve clamping. When the pressure value monitored by the pressure sensor 808 reaches the preset value, the clamping force of the clamping arm 204 on the raw material bar reaches the preset value. At this time, the controller 9 controls the first electric push rod 401 to stop feeding and complete the clamping;

[0069] S2: Start the driving motor 301 to drive the screw rod 304 to rotate. The screw rod 304 cooperates with the thread of the moving seat 305 and drives the moving seat 305 to move horizontally along the guide rail 303 under the guidance of the guide rail 303, and drives the laser rangefinder 10 and the plasma emitter 405 to move horizontally. At the same time, the linkage shaft 703 moves with the moving seat 305. The fixed rack 701 drives the linkage shaft 703 to rotate by engaging with the transmission gear 702. The linkage shaft 703 drives the rotating frame 708 to rotate and drives the counterweight plate 705 to perform circular motion. The counterweight plate 705 slides outward along the vertical rod under the action of centrifugal force, driving the movable pulley 706 away from the rotating frame 708, thereby making the other end of the connecting rope 710 pull the linkage plate 711 close to the linkage shaft 703 and compress the connecting spring 709. The movable plate 711 drives the side plate 605 to move horizontally through the positioning shaft. The side plate 605 drives the first valve core 602 to move horizontally through the connecting rod 603, so that the upper and lower ends of the through hole of the first valve core 602 are connected to the air inlet cylinder 606 and the three-way pipe 607 respectively, so that the gas in the nitrogen compression storage tank 616 and the argon compression storage tank 617 enters the three-way pipe 607 through the second regulating valve 608 and the third regulating valve 609 respectively, and then is introduced into the air inlet cylinder 606 through the first regulating valve 601, and then is introduced into the spiral groove 502 of the air jet cylinder 5 through the air inlet pipe 501 and is spirally ejected downward around the plasma emitter 405 under the guidance of the spiral strip 503, so that the argon and nitrogen form a high-speed vortex, accelerate the mixing of the nitrogen and argon, and in the subsequent plasma cutting process, the slag is quickly thrown away from the cutting seam by the centrifugal force of the vortex;

[0070] S3: Start the plasma emitter 405 and emit high-speed plasma to cut the raw material bar that has been turned. At the same time, the laser rangefinder 10 measures the surface distance between the moving plate 306 and the bar, and controls the first electric push rod 401 in real time through the controller 9 to drive the lifting plate 402 to move up and down, so that the plasma emitter 405 maintains a basically constant distance from the top of the raw material bar to achieve cutting. At the same time, as the output end of the first electric push rod 401 contracts, the cross-sectional thickness of the cut raw material bar increases. The controller 9 synchronously controls the output speed of the drive motor 301 to decrease, thereby reducing the moving speed of the plasma emitter 405 to ensure complete cutting of the thicker area. At the same time, the speed of the linkage shaft 703 decreases accordingly, so that the centrifugal force on the counterweight plate 705 is reduced, so that the linkage plate 711 and the first valve core 602 are reset to the right under the action of the connecting spring 709 and the compression spring 604 respectively, thereby increasing the conductive area between the through hole and the air intake cylinder 606 and the three-way pipe 607, thereby The flow rates of nitrogen and argon are increased, thereby improving the slag removal capacity and anti-oxidation effect. As the output end of the first electric push rod 401 is applied, the cross-sectional thickness of the raw material bar being cut decreases, and the controller 9 synchronously controls the output speed of the drive motor 301 to increase, so that the flow rates of nitrogen and argon are gradually restored. At the same time, the linkage shaft 703 drives the adjusting screw 715 to rotate at a reduced speed through the small pulley 712, the synchronous belt 713 and the large pulley 714. The adjusting screw 715 drives the connecting plate 610 to move to the right through the threaded engagement with the drive plate 613, thereby driving the second valve core 611 and the third valve core 612 to move to the right synchronously, thereby gradually reducing the connecting cross-sectional area between the three-way pipe 607 and the nitrogen inlet pipe 614 and gradually increasing the connecting area between the three-way pipe 607 and the argon inlet pipe 615. That is, in the early stage of cutting, the nitrogen ratio is large, thereby enhancing the slag removal capacity. In the middle stage of cutting, the nitrogen ratio is reduced and the argon ratio is increased, thereby suppressing oxidation. In the late stage of cutting, the argon ratio is further increased, thereby preventing terminal oxidation.

[0071] S4: The collection frame 101 collects the cut dental implant metal sleeve, controls the plasma emitter 405 and the drive motor 301 to stop running, and controls the output end of the first electric push rod 401 to contract, thereby driving the clamping arm 204 to move in the reverse direction and release the clamping.

[0072] In this embodiment, the integrated pressure sensor 808 and the closed-loop control system realize the intelligent clamping of the dental implant raw material rod. During the clamping process, the system monitors the mechanical state applied by the clamping arm 204 in real time and dynamically adjusts the clamping force to a preset threshold value, which not only ensures the stable fixation of the raw material rod during processing, but also avoids damage or deformation of the material surface due to excessive clamping force. This adaptive clamping mechanism significantly improves the processing accuracy and equipment reliability. By linking the speed of the drive motor 301 and the moving speed of the plasma emitter 405, the system can automatically adjust the cutting parameters according to the thickness change of the cutting section. When the processing thickness increases, the moving speed of the plasma emitter 405 is synchronously reduced and the gas flow is increased to ensure sufficient cutting and slag removal of the thick area; when the thickness decreases, the reverse adjustment is made to maintain efficiency. This dynamic balance design effectively solves the problem of overcutting or undercutting caused by uneven thickness in traditional cutting, ensuring the consistency and smoothness of the cut surface. It adopts a mechanical feedback structure that links centrifugal force with the gas valve core, which can independently adjust the mixing ratio of nitrogen and argon. In the early stage of cutting, the nitrogen ratio is prioritized to enhance the slag removal capability. In the middle stage, the argon ratio is gradually increased to inhibit the oxidation reaction. In the later stage, the argon ratio is further optimized to prevent terminal oxidation. This timed gas ratio strategy takes into account both cutting efficiency and material surface chemical stability, and is particularly suitable for the high-quality processing needs of biocompatible metals such as titanium alloys.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

The connecting shaft (803) is driven to rotate the turntable (202) by meshing with the driving gear (802) and the driven gear ring (801). The disc (202) drives the plurality of clamping arms (204) to approach each other through the cooperation of the plurality of guide grooves (203) and the corresponding connecting columns (205), so that the plurality of clamping arms (204) abut against the outside of the raw material bar to achieve clamping. When the pressure value monitored by the pressure sensor (808) reaches a preset value, the clamping force of the clamping arm (204) on the raw material bar reaches a preset value. At this time, the controller (9) controls the first electric push rod (401) to stop feeding, and the clamping is completed. S2: Start the driving motor (301) to drive the screw rod (304) to rotate. The screw rod (304) drives the movable seat (305) to move horizontally by cooperating with the thread of the movable seat (305), and drives the laser rangefinder (10) and the plasma emitter (405) to move horizontally. At the same time, the linkage shaft (703) moves following the movable seat (305). The fixed rack (701) drives the linkage shaft (703) to rotate by meshing with the transmission gear (702). The linkage shaft (703) drives the rotating frame (708) to rotate and drives the counterweight plate (705) to perform circular motion. The counterweight plate (705) slides outward along the vertical rod under the action of centrifugal force, driving the movable pulley (706) away from the rotating frame (708), thereby causing the other end of the connecting rope (710) to pull the linkage plate (711) close to the linkage shaft (703) and compress the connecting spring (709). The linkage plate (711) The side plate (605) is driven to move horizontally by the positioning shaft. The side plate (605) drives the first valve core (602) to move horizontally through the connecting rod (603), so that the upper and lower ends of the through hole of the first valve core (602) are connected to the air inlet cylinder (606) and the three-way pipe (607) respectively, so that the gas in the nitrogen compression storage tank (616) and the argon compression storage tank (617) enters the three-way pipe (607) through the second regulating valve (608) and the third regulating valve (609) respectively, and then is introduced into the air inlet cylinder (606) through the first regulating valve (601), and then is introduced into the spiral groove (502) of the jet cylinder (5) through the air inlet pipe (501) and is spirally ejected downward around the plasma emitter (405) under the guidance of the spiral strip (503), so that the argon and nitrogen form a high-speed vortex, accelerate the mixing of the nitrogen and argon, and quickly throw the slag away from the cutting seam by the centrifugal force of the vortex in the subsequent plasma cutting process; S3: The plasma emitter (405) is started to emit high-speed plasma to cut the raw material bar that has been turned. At the same time, the laser rangefinder (10) measures the surface distance between the movable plate (306) and the bar, and the controller (9) controls the first electric push rod (401) in real time to drive the lifting plate (402) to move up and down, so that the plasma emitter (405) and the top of the raw material bar are kept at a substantially constant distance to achieve cutting. At the same time, as the output end of the first electric push rod (401) contracts, the cross-sectional thickness of the raw material bar being cut increases. The controller (9) synchronously controls the output speed of the driving motor (301) to decrease, thereby reducing the moving speed of the plasma emitter (405) to ensure complete cutting of the thicker area. At the same time, the speed of the linkage shaft (703) is reduced, so that the centrifugal force on the counterweight plate (705) is reduced, so that the linkage plate (711) and the first valve core (602) are reset to the right under the action of the connecting spring (709) and the compression spring (604), respectively, so that the conductive area between the through hole and the air inlet cylinder (606) and the three-way pipe (607) is increased. As a result, the flow rate of nitrogen and argon increases, thereby improving the slag removal capacity and anti-oxidation effect. As the output end of the first electric push rod (401) is applied, the cross-sectional thickness of the cut raw material bar decreases, and the controller (9) synchronously controls the output speed of the drive motor (301) to increase, so that the flow rate of nitrogen and argon gradually recovers.

The adjusting screw (715) rotates at a reduced speed through the drive plate (613). The threaded engagement drives the connecting plate (610) to move rightward, thereby driving the second valve core (611) and the third valve core (612) to move rightward synchronously, thereby causing the connection cross-sectional area between the three-way pipe (607) and the nitrogen inlet pipe (614) to gradually decrease, and the connection cross-sectional area between the three-way pipe (607) and the argon inlet pipe (615) to gradually increase, that is, in the early stage of cutting, the nitrogen ratio is large, thereby enhancing the slag removal capability; in the middle stage of cutting, the nitrogen ratio is reduced, and the argon ratio is increased, thereby suppressing oxidation; in the late stage of cutting, the argon ratio is further increased, thereby preventing terminal oxidation; S4: The collection frame (101) collects the cut dental implant metal sleeve, controls the plasma emitter (405) and the drive motor (301) to stop running, and controls the output end of the first electric push rod (401) to contract, thereby driving the clamping arm (204) to move in the reverse direction and release the clamping.
