Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment, specifically a five-axis laser cutting device for dental mold manufacturing with positioning and clamping functions. Background Technology

[0002] 3D printing technology allows for the mass production of dental molds without the need for mold making. After the dental molds are produced, the excess support structure on the surface of the dental mold needs to be cut off by laser cutting equipment. The batch of dental molds are then transported by a transport device, and then placed on a five-axis machine by a robotic arm. The excess structure on the surface of the dental mold is cut off by laser. After the cutting is completed, the dental mold is removed from the five-axis machine by the robotic arm and placed in a receiving box.

[0003] When a dental model is placed on a five-axis machine, it needs to be restricted by the limiting structure on the machine. Currently, it is common practice to pre-leave limiting holes in the support structure of the dental model during 3D printing, and to pre-leave corresponding limiting pins on the five-axis machine. When the robot places the dental model on the five-axis machine, the limiting pins engage with the limiting holes to limit the dental model, making it easier for the five-axis machine to adjust its position. However, in order to ensure that the limiting pins can be quickly and smoothly installed in the limiting holes, the inner diameter of the limiting hole is slightly larger than the outer diameter of the limiting pin when the dental model is formed by 3D printing. When the five-axis machine tilts or shifts the dental model, the dental model will shift slightly on the machine, which will affect the cutting accuracy of the laser beam on the excess structure of the dental model.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-6The figure shows a five-axis laser cutting device for dental mold manufacturing with positioning and clamping functions, including: a fixed base 1 and a gantry slide rail 2 fixed on the upper part of the fixed base 1. A laser generator 3 is fixed on the top of the gantry slide rail 2, and a laser polarization lens 4 is mounted on the outer side of the top of the gantry slide rail 2 through a drive component. The drive component includes an axial drive component and a transverse drive component, which enables the laser polarization lens 4 to move laterally and axially. A slide rail seat 5 is fixed on the upper end face of the fixed base 1, and the slide rail seat 5 is arranged longitudinally. A moving platform 7 is arranged inside the slide rail seat 5. Two symmetrically distributed slide rails 14 are fixed on the bottom inner side of the slide rail seat 5, and two sliding blocks 15 that are slidably fitted on the outer surface of the slide rails 14 are fixed on the lower end face of the moving platform 7. A deflection component is arranged on the upper end face of the moving platform 7, which is used to drive the dental mold to deflect in position. It also includes: a positioning unit, which is used to limit the dental model. The positioning unit includes at least two pins 20 that are circumferentially distributed and inserted inside the deflection component. The pins 20 can be assembled with the limiting holes of the dental model. Each pin 20 is provided with a fixing component inside. The fixing component is used to fix the dental model and prevent the dental model from shifting between the pins 20. A triggering component is also provided between the pins 20 and the moving platform 7. The triggering component is used to drive the operation of the fixing component.

[0020] The deflection component includes a drive motor 12 fixed to one end face of the slide rail 5, and a threaded rod 13 fixedly installed at the output end of the drive motor 12. The threaded rod 13 rotatably passes through the slide rail 5. The lower end face of the moving platform 7 is threadedly fitted onto the outer surface of the sliding block 15. A protective plate 6 is also fixedly installed on the upper end face of the slide rail 5, and the moving platform 7 is placed between the protective plate 6 and the slide rail 5. A deflection motor 8 is fixedly installed on the upper end face of the moving platform 7, and the output end of the deflection motor 8 is perpendicular to the threaded rod 13. A bearing plate 9 is fixedly installed at the output end of the deflection motor 8, and the other end of the bearing plate 9 is rotatably fitted to the moving platform 7. A first limiting seat 10 is fixedly installed on the upper end surface of the carrier plate 9, and a second limiting seat 11 is slidably attached to the top of the first limiting seat 10. A motor is installed inside the first limiting seat 10, and the output end of the motor is used to drive the second limiting seat 11 to deflect coaxially on the top of the first limiting seat 10. A straight cylindrical cavity 16 is opened inside the first limiting seat 10, and the bottom of the pin 20 extends into the straight cylindrical cavity 16. Through the action of the deflection motor 8 and the motor, the carrier plate 9 or the second limiting seat 11 can be deflected, thereby adjusting the placement position of the dental mold, which facilitates the laser beam to cut the excess structure around the dental mold.

[0021] The positioning unit also includes at least one limiting cylinder 21 mounted on the outer wall of the pin 20. If there are multiple limiting cylinders 21, and they are equidistantly distributed circumferentially, the limiting cylinders 21 are connected to the pin 20, and a limiting post 24 is provided inside the limiting cylinder 21. A sliding post 22 that is slidably mounted with the limiting cylinder 21 is fixedly provided at one end of the limiting post 24 near the axis of the pin 20. A first spring 23 is sleeved on the outside of the limiting post 24, and the two ends of the first spring 23 are fixed to the sliding post 22 and the limiting cylinder 21, respectively. A sliding rod 25 is also coaxially slidably mounted inside the pin 20. A trapezoidal lever 26 is fixedly installed on the top of the 5. The end of the trapezoidal lever 26 slides in contact with the end of the slide post 22 away from the limiting post 24. A retaining ring 27 is also fixedly sleeved on the outer surface of the slide rod 25. A second spring 28 is fixedly installed between the bottom of the retaining ring 27 and the pin 20. The second spring 28 is sleeved on the outside of the slide rod 25. When the slide rod 25 moves downward with the trapezoidal lever 26, the end of the trapezoidal lever 26 can push the end of the slide post 22, so that the limiting post 24 extends out of the pin 20 and abuts against the inner wall of the limiting hole of the dental mold, thereby fixing the dental mold.

[0022] The axis of the limiting cylinder 21 is at an acute angle to the axis of the pin 20. When the trapezoidal push block 26 moves downward to push the sliding column 22, the bottom of the limiting column 24 extends downward to the pin 20. That is, when the limiting column 24 extends to push the limiting hole of the dental mold, it will also apply a force close to the upper end face of the second limiting seat 11 to the dental mold, thereby ensuring that the dental mold is fixed and limited in close contact with the upper end face of the second limiting seat 11.

[0023] The actuating components include a first movable disc 17 and a second movable disc 18 slidably mounted inside the cylindrical cavity 16. A tension spring 19 is fixedly arranged between the first movable disc 17 and the second movable disc 18, and the first movable disc 17 is located above the second movable disc 18. The bottom of each slide rod 25 is fixedly embedded inside the first movable disc 17. A traction rope 29 is rotatably mounted on the bottom of the second movable disc 18, and the traction rope 29 slides through the bottom of the cylindrical cavity 16. A winding component is provided inside the moving platform 7. When the winding component is running, it can wind and pull the traction rope 29, so that the second movable disc 18 moves downward with the first movable disc 17 through the tension spring 19, and the limit post 24 can be pushed out by triggering the slide post 22 through the trapezoidal lever 26.

[0024] The take-up component includes a slot inside the moving platform 7. A first rotating shaft 31 is rotatably mounted inside the slot, and a transmission gear 32 is fixedly fitted on the outer surface of the first rotating shaft 31. Several toothed grooves 30 are equidistantly distributed in a straight line on the outer surface of the protective plate 6, and the transmission gear 32 is movably meshed with the toothed grooves 30. A take-up shaft 33 is rotatably mounted on the upper end face of the moving platform 7, and the bottom of the traction rope 29 is fixed to the outer surface of the take-up shaft 33. One end of the take-up shaft 33 is connected to the outer surface of the first rotating shaft 31 by a synchronous gear and a synchronous toothed belt for transmission. When the moving platform 7 moves towards the bottom of the laser polarization lens 4 with the second limit seat 11, the meshing of the transmission gear 32 with the toothed grooves 30 allows the first rotating shaft 31 to rotate, thereby allowing the take-up shaft 33 to take up and pull the traction rope 29. Example 2: Please refer to Figures 7-9 This embodiment is a further explanation of other embodiments. The empty slot is set at the center of the mobile platform 7. The mobile platform 7 has a cavity inside. The cavity has two symmetrically distributed air supply units. The two air supply units are symmetrical about the first rotating shaft 31. The two air supply units respectively supply air to the tooth grooves 30 on both sides to remove impurities accumulated inside the tooth grooves 30. The air supply unit includes a hollow pipe 41 fixed to the side wall of the cavity. The end of the hollow pipe 41 away from the empty slot is fixedly connected to a number of exhaust pipes 42 that are distributed in a straight line at equal intervals. The port of the exhaust pipe 42 away from the hollow pipe 41 is inclined downward and has a narrow opening. When high-pressure gas is ejected through the narrow opening of the exhaust pipe 42, the flow rate of the ejected gas can be accelerated, thereby improving the removal effect on impurities inside the tooth grooves 30. Each hollow pipe 41 is also provided with an air blowing component between it and the transmission gear 32.

[0025] The air-blowing component includes a second rotating shaft 44 rotatably embedded inside a cavity. The second rotating shaft 44 is perpendicular to the first rotating shaft 31, and a first bevel gear 34 is fixedly mounted on the end of the second rotating shaft 44 near the transmission gear 32. The outer wall of the transmission gear 32 has an annular groove, and a second bevel gear 35 is fixedly mounted inside the annular groove. The second bevel gear 35 and the first bevel gear 34 are driven together. Two symmetrically distributed sealing sleeves 37 are provided on the outer side of each second rotating shaft 44, and the sealing sleeves 37 are fixed to the moving platform 7. A pushing turntable 36 is also fixedly mounted on the outer surface of the second rotating shaft 44, and an odd number of circumferentially distributed triangular protrusions are fixedly provided on the end face of the pushing turntable 36 near the sealing sleeve 37. A piston disc 38 is slidably mounted inside each sealing sleeve 37, and a sliding through-hole is fixedly provided on the end of the piston disc 38 near the pushing turntable 36. A third spring 39 is provided between the push rod 45 of the sealing sleeve 37 and the other end of the piston disc 38 and the sealing sleeve 37. One end of the two push rods 45 slides against the push turntable 36, and the other slides against the top of the triangular protrusion. A gas pipe 40 is fixedly connected between the sealing sleeve 37 and the hollow tube 41. A first one-way valve is provided at the connection between each gas pipe 40 and the sealing sleeve 37. A second one-way valve is also fixedly connected to the outer wall of the sealing sleeve 37. The flow direction of the first one-way valve is one-way flow from the sealing sleeve 37 to the gas pipe 40. The flow direction of the second one-way valve is one-way flow from the outside to the inside of the sealing sleeve 37. When the second rotating shaft 44 rotates with the push turntable 36, the odd number of triangular protrusions can alternately input pressurized gas into the inside of the hollow tube 41 through the gas pipe 40, thereby realizing continuous and uninterrupted gas supply. Example 3: Please refer to Figure 7 This embodiment is a further explanation of other embodiments. Both ends of the second rotating shaft 44 rotate through the moving platform 7, and the outer surface of the end of the second rotating shaft 44 away from the first bevel gear 34 is fixedly fitted with a brush plate 43. When the second rotating shaft 44 rotates with the brush plate 43, the bristles of the brush plate 43 can brush out the impurities inside the tooth groove 30.

[0026] Both ends of the tooth groove 30 are provided with rounded chamfers. The rounded chamfers make it easier for the bristles of the brush plate 43 to brush out the impurities inside the tooth groove 30. Working principle: When placing the dental mold on top of the second limiting seat 11, the moving platform 7 needs to be moved to the front end of the slide rail seat 5, i.e., the end away from the bottom of the laser polarization lens 4, by the drive motor 12. At this time, the moving platform 7 is in the position of... Figure 2 The position of the dental mold is determined so that the robotic arm can place the dental mold on the top of the second limiting seat 11. During the placement process, the pin 20 can be inserted into the limiting hole of the dental mold. The drive motor 12 drives the moving platform 7 to move the dental mold directly below the laser polarizing lens 4. During the movement, the meshing of the transmission gear 32 and the tooth groove 30 allows the winding shaft 33 to wind up the traction rope 29, thereby pulling the second movable disc 18 downward. As the slide rod 25 moves downward with the trapezoidal lever 26, it pushes the end of the slide column 22, causing the bottom of the limiting post 24 to push out and abut against the inner wall of the dental mold limiting hole, thus limiting and fixing the dental mold. When the trapezoidal lever 26 moves downward and pushes the slide column 22 until it can no longer move, the tension spring 19 will be stretched open. The reaction force generated by the tension spring 19 will also make the limiting post 24 tightly abut against the inner wall of the limiting hole, thereby ensuring that the dental mold can be stably limited to the upper end face of the second limiting seat 11. No matter how the upper end face of the second limiting seat 11 deflects, the dental mold will not shift, thus ensuring the accuracy of the dental mold during laser cutting.

[0027] Each time the moving platform 7 moves, the meshing of the first bevel gear 34 and the second bevel gear 35 causes the second rotating shaft 44 to rotate, allowing the brushes of the two brush plates 43 to brush out the impurities accumulated inside the tooth groove 30, preventing excessive accumulation of impurities from affecting the transmission of the transmission gear 32. Moreover, when the second rotating shaft 44 rotates, it also drives the pusher turntable 36 to rotate. Several triangular protrusions on the end face of the pusher turntable 36 can alternately push the two push rods 45 located on the same side. Under the action of the first one-way valve, the second one-way valve, and the third spring 39, high-pressure gas can be continuously input into the hollow tube 41 and output through several exhaust pipes 42. The high-pressure airflow blowing on the surface of the tooth groove 30, combined with the action of the brush plates 43, can more effectively ensure the cleanliness of the inside of the tooth groove 30 and prevent the accumulation of particulate impurities.
