Description

Technical Field

[0001] This invention relates to the field of sandblasting equipment technology, and in particular to a novel environmentally friendly dental implant sandblasting equipment and its usage method. Background Technology

[0002] Dental implants, also known as oral implants or artificial tooth roots, are surgically inserted into the upper and lower jawbones at the site of tooth loss. After the surgical wound heals, a prosthetic tooth is installed on top of it. Studies have shown that a moderately rough surface structure can increase the surface area of ​​the implant and promote its integration with human bone tissue. Therefore, the implant systems currently used in clinical practice generally have rough surfaces of varying degrees obtained through various surface treatments. Sandblasting is one of the most widely used surface treatment processes.

[0003] Chinese patent CN202310892093.2 discloses a novel environmentally friendly dental implant sandblasting device, including a machine body. The top of the machine body is equipped with a material storage chamber and a sandblasting chamber. The designed implant sandblasting roller can simultaneously sandblast a large number of implants at one time, increasing sandblasting efficiency. When the implant sandblasting roller rotates, it can increase the sandblasting area of ​​different positions of the implant, preventing the situation where implants are stacked and cannot be sandblasted. It is equipped with a handheld spray gun for individual sandblasting operation on a single implant, which does not conflict with the automatic sandblasting and can be operated simultaneously, reducing labor intensity and improving production efficiency. The automatic sandblasting robotic arm is equipped with a control panel for the user to control the position of the mechanical rotating arm in the automatic sandblasting robotic arm, thereby moving the sandblasting pipe at the bottom.

[0004] However, this technical solution has certain shortcomings in use. Due to the small size of the implant, it is not convenient to position and continuously sandblast during actual processing. The roller method mentioned above is also not very applicable. Multiple implants are easy to pile up and get stuck in the holes on the outside of the cylinder, affecting the overall processing. At the same time, the wear on the implant is greater when the cylinder rolls, which affects the overall processing efficiency and the precision is lower. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel environmentally friendly dental implant sandblasting equipment and its usage method. This equipment achieves automated continuous sandblasting through a sandblasting cabinet and processing mechanism, thus solving the problems of low efficiency and precision.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel environmentally friendly dental implant sandblasting device includes a support frame and a cabinet on the support frame. A grid plate is fixedly connected to the inner cavity of the cabinet. A processing mechanism is provided on the grid plate.

[0011] The input component includes: a stepper motor disposed below the grid plate; an input roller disposed on the output shaft of the stepper motor; a gear ring b disposed on the input roller; a horizontal plate disposed on the grid plate; a gear a disposed at one end of the horizontal plate; a cam disposed at the other end of the horizontal plate; a pulley a disposed at one end of the gear a and the cam; and a belt a disposed on the pulley a.

[0012] The material feeding assembly includes: a support plate disposed on the grid plate; two sets of outer guide plates disposed on the support plate; two sets of tapered conveyor belts disposed within the support plate; three sets of tapered rollers disposed within the tapered conveyor belts; a feeding trough formed between the two sets of tapered conveyor belts; gears b, two sets of gears b disposed at the bottom of the two sets of tapered conveyor belts and meshing with each other; gear c, disposed on the grid plate; pulley b, disposed on gear c and gear b; belt b, disposed on pulley b; and a tapered guide plate disposed at one end of the two sets of outer guide plates.

[0013] The receiving assembly includes: a U-shaped seat disposed on multiple sets of notched slots; a bottom tube fixedly connected to the underside of the U-shaped seat; a traction rod movably connected inside the bottom tube; a return spring disposed on the traction rod and the bottom tube; a receiving seat movably connected to the U-shaped seat; a seat groove formed on the receiving seat; a receiving plate movably connected inside the receiving seat; and a cross-shaped upright plate disposed on the receiving assembly. The following components are included: a base; a longitudinal lead screw mounted on the cross plate; a longitudinal nut threaded onto the longitudinal lead screw; an adjusting member mounted on the longitudinal nut; a worm gear mounted at the top of the longitudinal lead screw; a bidirectional lead screw mounted on the cross plate; two sets of transverse nuts threaded onto the bidirectional lead screw; a worm wheel mounted on the bidirectional lead screw; and a clamping member mounted on the two sets of transverse nuts.

[0014] The sandblasting assembly includes: a top ring disposed within the cabinet; two sets of clamps disposed on two sets of nozzles; a connecting plate disposed between the two sets of clamps; a guide groove formed on the connecting plate; a servo motor disposed on the connecting plate; a toothed block disposed on the output shaft of the servo motor; and a toothed ring c disposed on the top ring.

[0015] The feeding assembly includes: a power base disposed within the cabinet; a gear d disposed within the power base; a gear e disposed at the bottom end of gear d; two sets of gears f disposed on both sides of gear d; half gears disposed on the two sets of gears f; a limiting block disposed within the power base; a rack disposed on the limiting block; and a push block disposed at one end of the rack.

[0016] A sandblasting method for a novel environmentally friendly dental implant sandblasting device includes the following steps:

[0017] Step 1, Material Feeding Process: Multiple workpieces are placed upside down into the feeding troughs of two sets of conical conveyor belts. The stepper motor drives the toothed ring b to rotate a certain number of times. The gear c meshes with the outer periphery of the toothed ring b, thus synchronously rotating through the stepper motor's stepping drive. The belt b on the pulley b drives the gear b to rotate, and the gears b on the two sets of conical conveyor belts mesh with each other. That is, the gear b drives the two sets of conical conveyor belts to move towards each other. Further, the friction force drives the movement of the workpieces in the feeding troughs to complete the feeding process.

[0018] Step 2, Material Receiving Process: The stepper motor rotates at a certain angle, causing the notch on the outer disk to stop in front of the conical guide plate. The workpiece, which is gradually handed over, is guided by the conical guide plate and the clamping device and falls onto the receiving plate of the receiving seat. The weight of the workpiece itself causes the receiving plate to move down, and the longitudinal nut moves down synchronously, driving the worm gear at the top of the longitudinal lead screw to rotate. Through the meshing of the worm wheel and the worm gear, the bidirectional lead screw rotates. The rotation of the bidirectional lead screw drives the two sets of transverse nuts to move inward and towards each other. The two sets of transverse nuts drive the clamping device to straighten and clamp the workpiece, so as to achieve adaptive positioning of the workpiece. The rotation of the outer disk is synchronized with the material delivery, so that the workpiece can be continuously replenished into the receiving seat, and the continuous stepping rotation of the outer disk can continuously transport materials for subsequent sandblasting.

[0019] Step 3, Sandblasting process: When gear a meshes with gear ring b, the gear ring b drives gear a to rotate when rotating at a certain angle. The belt on pulley a drives the cam to rotate synchronously, so that the cam's convex end faces upward and squeezes the traction rod, causing the upper receiving seat and workpiece to move upward against the return force of the return spring, so that the threaded end of the workpiece enters the top ring.

[0020] When the servo motor is powered on, it drives the tooth block to rotate. Through meshing with the tooth ring c and the guidance of the guide groove, the two sets of nozzles slide back and forth along the top ring and around the workpiece. The pump pressurizes the tank and uses high pressure to uniformly sandblast the workpiece from the two sets of nozzles.

[0021] Step 4, feeding process: The optical sensor can monitor and provide feedback to the system in real time. When sandblasting is completed, the stepper motor continues to operate to drive the continuous feeding and sandblasting of subsequent workpieces.

[0022] Through the meshing of gear e and gear ring a, the rotation of gear ring a drives gear d to rotate. Two sets of gears f mesh with gear d. The rotation of gear d drives the two sets of gears f to rotate in opposite directions. The upper half gear of gear f meshes with the rack. When the half gear rotates to mesh, it can drive the push block at the other end of the rack to move into the seat groove of the receiving seat that is turned to that position, pushing out the sandblasted workpiece to complete the feeding. When it cannot mesh, the rack is reset by the spring rebound force in the power seat to realize reciprocating feeding.

[0023] Step 5, Recycling Process: The negative pressure dust collection device uses its internal exhaust structure to create negative pressure, which is then used to remove dust from the cabinet and reduce pollution.

[0024] The waste hopper collects heavier titanium waste. During collection, a cyclone filter draws in lighter waste from the cabinet by rotation and separates the waste particles by centrifugal force, allowing the waste to be recycled.

[0025] The beneficial effects of this invention are as follows:

[0026] (1) The present invention uses a stepper motor and multiple sets of transmission structures of a certain proportion to synchronously perform the feeding, delivery, sandblasting and feeding processes to realize continuous sandblasting operation, which greatly improves the sandblasting efficiency. At the same time, an adaptive receiving structure is set to ensure the positioning effect and processing accuracy of the workpiece.

[0027] (2) The present invention is equipped with a PLC+touch screen control system through an intelligent control panel, which can accurately adjust the sandblasting pressure, abrasive flow rate and sandblasting angle to adapt to different implant materials. The sandblasting effect is detected by optical sensors, and the real-time monitoring and feedback system automatically adjusts the parameters to ensure consistent processing.

[0028] (3) This invention achieves efficient separation of abrasive and metal scrap through a dual recovery mechanism of cyclone separation and filtration adsorption in a high-efficiency waste recycling system, reducing environmental pollution. The enclosed working chamber, combined with a negative pressure dust collection device, effectively suppresses dust diffusion and protects the health of operators.

[0029] In summary, the present invention has the advantages of high efficiency and high precision. Attached Figure Description

[0050] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] Example 1: As Figures 1-3 As shown, this embodiment provides a novel environmentally friendly dental implant sandblasting device, including a support 1 and a cabinet 11 on the support 1. A grid plate 116 is fixedly connected in the inner cavity of the cabinet 11. A processing mechanism 2 is provided on the grid plate 116. The processing mechanism 2 includes a receiving component 21, an input component 22, a material delivery component 23, a receiving component 24, a sandblasting component 25, and a feeding component 26 provided on the grid plate 116.

[0053] Both ends of the cabinet 11 are equipped with hatches 112, the outside of the cabinet 11 is equipped with a control panel 113, the top of the cabinet 11 is equipped with a negative pressure dust collection device 114, and one end of the hatch 112 is equipped with an optical sensor 115.

[0054] In this embodiment, the door 112 is a sealed structure, which facilitates opening for material handling. Its side optical sensor 115 can monitor and provide feedback to the system in real time. The optical sensor 115 detects the sandblasting effect and automatically adjusts the parameters to ensure consistent processing. The control panel 113 is an intelligent control unit equipped with a PLC + touch screen control system, which can accurately adjust the sandblasting pressure (0.1-0.5MPa), abrasive flow rate (5-20g / s), and sandblasting angle (30°-90°) to adapt to different implant materials. The negative pressure dust collection device 114 creates negative pressure through the internal exhaust structure to remove dust from the cabinet 11.

[0055] A waste hopper 12 is installed at the bottom of the cabinet 11. A cyclone filter device 13 and a sandblasting device 14 are provided on one side of the support 1. The cyclone filter device 13 includes: a cylinder 131, which is mounted on the support 1; and a dust extraction pipe 132, which is mounted on the cylinder 131. The sandblasting device 14 includes: a tank 141, which is mounted on the support 1; a pump 142, which is located outside the tank 141; a hose 143, which is located at the bottom of the tank 141; a pressure sensor 144, which is located outside the tank 141; a double-ended connector 145, which is located at the end of the hose 143; and two sets of nozzles 146, which are located at both ends of the double-ended connector 145.

[0056] In this embodiment, the waste hopper 12 collects heavy titanium waste. During collection, the cyclone filter 13 draws in the lighter waste from the cabinet 11 by rotation and separates the waste particles by centrifugal force, which can then be recycled. The pump 142 pressurizes the tank 141 and performs sandblasting under high pressure to change the surface roughness of the workpiece. The hose 143 on the nozzle 146 is designed for easy adjustment and allows the nozzle 146 to move.

[0057] Example 2: Figures 4-18 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0058] The receiving component 21 includes: an inner plate 211, which is disposed on the grid plate 116; an outer plate 212, which is disposed outside the inner plate 211; a notch 213, which is provided on the outer plate 212; and a toothed ring a214, which is disposed on the inner plate 211.

[0059] In this embodiment, the outer disk 212 is provided in the notch 213 to receive the workpiece, and the inner disk 211 is used to drive the outer disk 212 to continuously process and transport the workpiece.

[0060] The input component 22 includes: a stepper motor 221, which is located below the grid plate 116; an input roller 222, which is located on the output shaft of the stepper motor 221; a gear ring b223, which is located on the input roller 222; a horizontal plate 224, which is located on the grid plate 116; a gear a2241, which is located at one end of the horizontal plate 224; a cam 2242, which is located at the other end of the horizontal plate 224; a pulley a2243, which is located at one end of the gear a2241 and the cam 2242; and a belt a2244, which is located on the pulley a2243.

[0061] In this embodiment, when the stepper motor 221 is powered on, it will drive the entire receiving assembly 21 to rotate through the input roller 222, so as to realize the continuous transportation of the workpiece. The gear a2241 meshes with the gear ring b223. ​​When rotating, the gear ring b223 drives the gear a2241 to rotate, and the belt a2244 on the pulley a2243 drives the cam 2242 to rotate synchronously.

[0062] It should be noted that the circumference of the gear ring b223 is in a certain proportion to the circumference of the gear a2241, and the tooth pitch is the same. When the gear ring b223 rotates a certain angle in two steps, it can drive the cam 2242 to rotate one revolution.

[0063] The feeding assembly 23 includes: a support plate 231 disposed on the grid plate 116; two sets of outer guide plates 232 disposed on the support plate 231; two sets of tapered conveyor belts 233 disposed within the support plate 231; three sets of tapered rollers 234 disposed within the tapered conveyor belts 233; a feeding trough 235 formed between the two sets of tapered conveyor belts 233; and gear b2. 36. Two sets of gears b236 are located at the bottom of two sets of conical conveyor belts 233 and mesh with each other; gear c2361 is located on the grid plate 116; pulley b2362 is located on gear c2361 and gear b236; belt b2363 is located on pulley b2362; conical guide plate 237 is located at one end of the two sets of outer guide plates 232.

[0064] In this embodiment, gear c2361 meshes with the outer periphery of gear ring b223, thereby rotating synchronously driven by stepper motor 221. Through the transmission of belt b2363 on pulley b2362, gear b236 rotates, and gears b236 mesh with each other on two sets of conical conveyor belts 233. That is, gears b236 drive the two sets of conical conveyor belts 233 to move towards each other, and further drive the movement of the workpiece in the feeding trough 235 through friction to complete the feeding. The conical conveyor belt 233 supported by conical roller 234, the outer guide plate 232, and the conical guide plate 237 have the same taper as the thread end of the workpiece. When the workpiece is inverted, it can be restricted, which can improve the stability while ensuring the material conveying effect.

[0065] It should be noted that the circumferences of gear c2361 and gear ring b223 are in a certain proportion. While gear ring b223 rotates by a certain angle, the conical roller 234 on transmission gear c2361 rotates a certain number of times to realize the transportation of the workpiece in one position, and further realize synchronous material delivery.

[0066] The receiving assembly 24 includes: a U-shaped seat 241, which is disposed on multiple sets of notched slots 213; a bottom tube 2411, which is fixedly connected to the bottom of the U-shaped seat 241; a traction rod 2412, which is movably connected to the bottom tube 2411; a return spring 2413, which is disposed on the traction rod 2412 and the bottom tube 2411; a receiving seat 242, which is movably connected to the U-shaped seat 241; a seat groove 2421, which is formed on the receiving seat 242; a receiving plate 243, which is movably connected to the receiving seat 242; and a cross-shaped upright plate 2431, which is disposed on the receiving seat 242. (The last part, "longitudinal," appears to be a fragment and doesn't need a direct translation.) A lead screw 2432 is mounted on a cross plate 2431; a longitudinal nut 2433 is threaded onto the longitudinal lead screw 2432; an adjusting member 2434 is mounted on the longitudinal nut 2433; a worm gear 2435 is mounted at the top of the longitudinal lead screw 2432; a bidirectional lead screw 2436 is mounted on the cross plate 2431; two sets of transverse nuts 2437 are threaded onto the bidirectional lead screw 2436; a worm wheel 2438 is mounted on the bidirectional lead screw 2436; and a clamping member 2439 is mounted on the two sets of transverse nuts 2437.

[0067] In this embodiment, the workpiece gradually delivered by the feeding component 23 will be guided by the clamping component 2439 and fall onto the receiving plate 243 of the receiving seat 242. The weight of the workpiece itself will cause the receiving plate 243 to move downward, and the longitudinal nut 2433 will move downward simultaneously, driving the worm gear 2435 at the top of the longitudinal lead screw 2432 to rotate. The meshing of the worm wheel 2438 and the worm gear 2435 will drive the bidirectional lead screw 2436 to rotate. The rotation of the bidirectional lead screw 2436 will drive the two sets of transverse nuts 2437 to move inward and towards each other. The two sets of transverse nuts 2437 will drive the clamping component 2439 to straighten and clamp the workpiece, so as to achieve adaptive positioning of the workpiece.

[0068] The sandblasting assembly 25 includes: a top ring 251, which is located inside the cabinet 11; clamps 252, with two sets of clamps 252 located on two sets of nozzles 146; a connecting plate 253, which is located between the two sets of clamps 252; a guide groove 254, which is formed on the connecting plate 253; a servo motor 255, which is located on the connecting plate 253; a toothed block 256, which is located on the output shaft of the servo motor 255; and a toothed ring c257, which is located on the top ring 251.

[0069] In this embodiment, two sets of nozzles 146 are movably connected to the top ring 251 via the connecting plate 253 on the clamp 252. When the servo motor 255 is powered on, it drives the tooth block 256 to rotate. Through meshing with the tooth ring c257 and the guidance of the guide groove 254, the two sets of nozzles 146 slide back and forth along the top ring 251 to achieve uniform sandblasting of the workpiece.

[0070] The feeding assembly 26 includes: a power base 261, which is located inside the cabinet 11; a gear d262, which is located inside the power base 261; a gear e263, which is located at the bottom end of the gear d262; two sets of gears f264, which are located on both sides of the gear d262; a half gear 265, which is located on the two sets of gears f264; a limiting block 266, which is located inside the power base 261; a rack 267, which is located on the limiting block 266; and a push block 268, which is located at one end of the rack 267.

[0071] In this embodiment, gear e263 meshes with gear ring a214. The rotation of gear ring a214 drives gear d262 to rotate. Two sets of gears f264 mesh with gear d262. The rotation of gear d262 drives the two sets of gears f264 to rotate in opposite directions. The upper half gear 265 of gear f264 meshes with rack 267. When half gear 265 rotates to mesh, it can drive the push block 268 at the other end of rack 267 to move into the seat groove 2421 of receiving seat 242 at that position to push out the sandblasted workpiece and complete the feeding. When it cannot mesh, the rack 267 is reset by the spring rebound force in power seat 261 to realize reciprocating feeding.

[0072] It should be noted that gear e263, gear ring a214, gear d262, two sets of gears f264 and half gear 265 are all in a certain proportion to ensure that the reciprocating extension and retraction amplitude of rack 267 is consistent and synchronized with the stepping structure.

[0073] Example 3: Figures 1-18 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0074] A sandblasting method for a novel environmentally friendly dental implant sandblasting device includes the following steps:

[0075] Step 1, Material Feeding Process: Multiple workpieces are placed upside down into the feeding troughs 235 of two sets of conical conveyor belts 233. The stepper motor 221 drives the gear ring b223 to rotate a certain number of revolutions. The gear c2361 meshes with the outer periphery of the gear ring b223, thereby synchronously rotating through the stepper motor 221. The belt b2363 on the pulley b2362 drives the gear b236 to rotate. The gears b236 on the two sets of conical conveyor belts 233 mesh with each other, that is, the gears b236 drive the two sets of conical conveyor belts 233 to move towards each other. Further, the friction force drives the movement of the workpieces in the feeding troughs 235 to complete the feeding process.

[0076] Step 2, Receiving Process: Stepper motor 221 rotates a certain angle, causing the notch 213 on the outer disc 212 to stop in front of the tapered guide plate 237. The workpiece, which is gradually handed over, is guided by the tapered guide plate 237 and the clamping member 2439 and falls onto the receiving plate 243 of the receiving seat 242. The weight of the workpiece itself causes the receiving plate 243 to move downward, and the longitudinal nut 2433 moves downward simultaneously, driving the worm gear 2435 at the top of the longitudinal lead screw 2432 to rotate, which is then rotated by the worm wheel 243. The meshing of the worm gear 2435 with the double-acting screw 2436 drives the double-acting screw 2436 to rotate. The rotation of the double-acting screw 2436 drives the two sets of transverse nuts 2437 to move inwards towards each other. The two sets of transverse nuts 2437 drive the clamping parts 2439 to straighten and clamp the workpiece, so as to achieve adaptive positioning of the workpiece. The rotation of the outer disk 212 is synchronized with the feeding, so that the workpiece can be continuously replenished into the receiving seat 242, and the outer disk 212 continuously feeds the subsequent sandblasting material through continuous stepping rotation.

[0077] Step 3, Sandblasting process: When gear a2241 meshes with gear ring b223, gear ring b223 drives gear a2241 to rotate when rotating at a certain angle. The belt a2244 on pulley a2243 drives cam 2242 to rotate synchronously, so that the convex end of cam 2242 faces upward and squeezes the traction rod 2412, so that the upper receiving seat 242 and the workpiece overcome the rebound force of the return spring 2413 and move upward, so that the threaded end of the workpiece enters the top ring 251.

[0078] When the servo motor 255 is powered on, it drives the tooth block 256 to rotate. Through meshing with the tooth ring c257 and the guidance of the guide groove 254, the two sets of nozzles 146 slide back and forth along the top ring 251 and around the workpiece. The pump 142 pressurizes the tank 141, and the workpiece is uniformly sandblasted by the two sets of nozzles 146 under high pressure.

[0079] Step 4, feeding process: The optical sensor 115 can monitor and provide feedback to the system in real time. When sandblasting is completed, the stepper motor 221 continues to operate to drive the continuous feeding and sandblasting of subsequent workpieces.

[0080] Through the meshing of gear e263 and gear ring a214, the rotation of gear ring a214 drives gear d262 to rotate. Two sets of gears f264 mesh with gear d262. The rotation of gear d262 drives the two sets of gears f264 to rotate in opposite directions. The upper half gear 265 of gear f264 meshes with rack 267. When half gear 265 rotates to mesh, it can drive the push block 268 at the other end of rack 267 to move into the seat groove 2421 of the receiving seat 242 that has been turned to that position, pushing out the sandblasted workpiece to complete the feeding. When it cannot mesh, the rack 267 is reset by the spring rebound force in the power seat 261 to realize reciprocating feeding.

[0081] Step 5, Recycling Process: Negative pressure is created through the internal exhaust structure of the negative pressure dust collection device 114 to remove dust from the inside of the cabinet 11 and reduce pollution;

[0082] The waste hopper 12 collects the heavier titanium waste. During collection, the cyclone filter 13 draws in the lighter waste from the cabinet 11 by rotation and separates the waste particles by centrifugal force, so that the waste can be recycled.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
