Description

Technical Field

[0001] The present invention relates to the technical field of appliance processing equipment, and in particular to a flexible processing equipment for a bracketless invisible orthodontic appliance. Background Art

[0002] Compared with the wire correction in the past, bracketless invisible orthodontic appliances are more aesthetically pleasing and meet the beauty needs of today's young people. At the same time, because bracketless invisible orthodontic appliances are easy to disassemble and assemble, and compared with wire correction, they are easier to clean and install, making them more widely used.

[0003] In the production process of bracketless invisible orthodontic appliances, 3D printers are generally used to design and model the collected user's dental correction conditions. In order to facilitate subsequent processing during the printing process, some bracketless invisible orthodontic appliances will add connectors around the appliances during printing, and then these connectors will be polished in subsequent processing.

[0004] After searching the existing patent publication number: CN116871902A, a flexible processing equipment for bracketless invisible orthodontic appliance is found. In order to solve the problem that flexible positioning is not convenient during processing, which makes it easy to cause damage to the appliance during processing, its beneficial effects are described as "the present invention realizes the full-process flexible adsorption operation of the appliance through the translation suction cup, the first movable adsorption cup and the first movable adsorption cup, which is convenient for maintaining the stability of the appliance during the processing and avoiding damage". Although the effect of flexible adsorption is achieved to a certain extent, since the surface of the appliance is modeled according to the tooth correction conditions of different users, there will be gaps of different sizes and different shapes on the surface of the appliance, which will lead to poor sealing and weak connection stability when the processing equipment performs flexible negative pressure suction on the appliance. In the subsequent processing process, the appliance is prone to fall off when vibrated. Summary of the invention

While ensuring flexible adsorption, the stability of the orthodontic appliance during processing is improved. The setting of the alarm mechanism can accurately display the problem location when the flexible adsorption mechanism, the clamping mechanism and the anti-slipping mechanism are loose, so as to facilitate maintenance personnel to quickly repair them.

[0007] Preferably, the top of the tray is provided with a plurality of placement grooves for placing the orthodontic appliances, and the outer sides of the placement grooves are provided with a plurality of clamping shafts for clamping the orthodontic appliances.

[0008] Preferably, the feeding mechanism includes a fixed seat, which is arranged in the equipment body and is located directly below the processing area. A rectangular through groove is opened on the processing area corresponding to the fixed seat. The four corners of the fixed seat are all slidably connected with sliding limit rods. The top ends of the multiple sliding limit rods are commonly fixedly connected to a support plate. A plurality of vertically arranged trays are provided on the top of the support plate. Under the transmission of the feeding mechanism, stable indirect feeding will be carried out, without the need for manual continuous feeding, thereby improving processing efficiency.

[0009] Preferably, a threaded ring is embedded and rotatably connected at the center of the fixed seat, a threaded rod is threadedly connected to the inner thread of the threaded ring, and the top of the threaded rod is fixedly connected to the bottom of the support plate, the bottom end of the threaded ring is fixedly connected to a main gear, and the main gear is meshingly connected to a secondary gear, and the bottom of the fixed seat is fixedly connected to a mounting frame, and a motor is fixedly installed on the mounting frame. The top of the output shaft of the motor is fixedly connected to the center of the secondary gear, and the support plate is pushed upward by the transmission of the motor and related structures. By adjusting the switch and rotation frequency of the motor, indirect automatic lifting and feeding of multiple trays can be achieved, so that each tray of orthodontic appliances continues to appear in the processing area, which facilitates the subsequent grabbing of the orthodontic appliances and improves the processing efficiency.

[0010] Preferably, the material receiving mechanism includes a first electric push rod and a material guide box. The first electric push rod is fixedly installed on the processing area, and the end of the output shaft is close to the rectangular through groove. The material guide box is located directly below the bottom end of the equipment body and is provided with a material receiving box for conveniently receiving the tray. The outer side of the material receiving box is provided with a handle for convenient grasping. The output shaft of the first electric push rod is extended to push the tray into the material guide box and slide it into the material receiving box for centralized collection, which is convenient for personnel to take and re-load the orthodontic appliance, further improving the efficiency of the processing equipment in and out of the material.

[0011] Preferably, the flexible adsorption mechanism includes a second electric push rod, which is fixedly connected to the bottom of the moving block on the electric slide rail, the output shaft of the second electric push rod is fixedly connected to a connecting plate, and the end of the second electric push rod away from the output shaft is fixedly connected to the fixed plate in a through-type manner, and a plurality of piston rods and piston cylinders are fixedly connected between the fixed plate and the connecting plate, respectively, and the piston rods are connected to the corresponding piston cylinder pistons, an air guide tube is inserted into the bottom end of the piston cylinder, and a connecting pipe is inserted into the end of the air guide tube away from the piston cylinder, and a solenoid valve is installed. By controlling the output shaft of the second electric push rod to rise and fall, the flexible adsorption mechanism at the bottom end of the output shaft is driven to move closer to the orthodontic appliance, thereby achieving accurate grasping of the orthodontic appliance.

[0012] Preferably, the bottom end of the connecting tube is fixedly connected to the connecting plate in a through-type manner, and the bottom ends of multiple connecting tubes passing through the connecting plate are fixedly connected to a connecting block, a cavity is opened in the connecting block, and the bottom of the connecting block is fixedly connected to a rubber anti-skid pad that matches the top of the orthodontic appliance, and a through hole is opened in the center of the rubber anti-skid pad, the cavity is respectively connected to the through holes on the connecting tube and the rubber anti-skid pad, and the bottom of the cavity is slidably connected to a short tube, which is fixedly connected in the through hole, and a plurality of spherical rubber bumps are provided at the bottom of the rubber anti-skid pad. When the orthodontic appliance is attracted by negative pressure and under strong negative pressure, the bottom of the rubber anti-skid pad is squeezed, and since the rubber anti-skid pad is made of rubber material, the deformation of the rubber anti-skid pad will cause the overflowing soft rubber to fill the gap at the top of the orthodontic appliance, thereby improving the sealing of the negative pressure attraction between the two and enhancing the stability of the orthodontic appliance when it is attracted.

[0013] Preferably, the clamping mechanism includes two piston blocks, which are respectively connected to the inner wall pistons at both ends of the cavity, and the opposite sides of the two piston blocks are fixedly connected with a connecting shaft, a sealing sleeve is sleeved on the connecting shaft, and the sealing sleeve is connected to the connecting shaft piston, the sealing sleeve is fixedly connected to the inner wall of the cavity, and the end of the connecting shaft away from the piston block passes through the connecting block and is fixedly connected with a clamping block, and exhaust holes are provided on the inner walls of the two ends of the cavity opposite to the piston blocks. As the flexible adsorption mechanism flexibly adsorbs the top of the orthodontic device, the two piston blocks in the clamping mechanism will approach each other under negative pressure, and pull the clamping block toward the connecting block through the connecting shaft. As the two clamping blocks approach, the two sides of the orthodontic device will be clamped accordingly, thereby further improving the stability of the orthodontic device during flexible adsorption and avoiding the orthodontic device from falling off due to vibration during subsequent processing.

[0014] Preferably, the anti-slip mechanism includes an air guide cavity, which is arranged in the clamping block, and the upper and lower ends of the air guide cavity are respectively piston-connected with the first piston shaft and the second piston shaft, one end of the first piston shaft is located outside the air guide cavity, and the bottom ends of the two sealing sleeves are rotatably connected with an L-shaped clamping block, the bottom end of the second piston shaft passes through the sealing sleeve and is located on the top side of the L-shaped clamping block, and a spring wire is fixedly connected between the top of the L-shaped clamping block and the bottom end of the clamping block. When the two clamping blocks are attracted to each other by negative pressure, the air pressure in the air guide cavity increases, thereby pushing the bottom end of the second piston shaft out of the clamping block and squeezing the L-shaped clamping block to deflect at a certain angle. At this time, the other end of the L-shaped clamping block will push the bottom of the orthodontic device upward, so that a closer fit is formed between the top of the orthodontic device and the rubber anti-slip pad, thereby further improving the air tightness between the two.

[0015] Preferably, the alarm mechanism includes a pressure sensor. There are two pressure sensors, which are respectively fixedly connected to the two ends of the tops of the two connecting blocks. The tops of the two clamping blocks are fixedly connected with rubber abutment blocks that match the pressure sensors. A two-color alarm light is fixedly installed on one side of the connecting block. The two-color alarm light is provided with a two-color light area. When the clamping block on one side accidentally becomes loose, resulting in the inability to form a stable abutment relationship between the pressure sensor and the rubber abutment block, the color light area on one side of the two-color alarm light lights up, which makes it convenient for users to immediately find the problem location and then remind maintenance personnel to quickly repair it, thereby improving the practicality and intelligent effect of the equipment.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] 1. By setting up a feeding mechanism, the output shaft of the motor is rotated in conjunction with the main gear and the threaded ring to drive the threaded ring to rotate. When the threaded ring rotates, the threaded rod connected with the thread will push the support plate upward. By adjusting the switch and rotation frequency of the motor, it can achieve indirect automatic lifting and feeding of multiple trays, so that each tray of orthodontic appliances continues to appear in the processing area, which is convenient for the subsequent grabbing of the orthodontic appliances and improves the processing efficiency;

[0018] 2. By setting up a material receiving mechanism and utilizing the telescopic movement of the first electric push rod, when all the braces in the tray are grabbed and left the processing area, the first electric push rod in the material receiving mechanism is started, so that the output shaft of the first electric push rod extends, the tray is pushed into the material guide box, and then slides into the material receiving box for centralized collection, which is convenient for personnel to take and re-load the braces, further improving the efficiency of material feeding and unloading of the processing equipment;

[0019] 3. By setting a flexible adsorption mechanism, the air in the piston rod and the piston cylinder is used to form negative pressure when the piston cylinder moves downward following the connecting plate. The air guide tube plugged into the piston cylinder can release and maintain the negative pressure by controlling the solenoid valve installed on itself. When the solenoid valve is opened, the negative pressure in the piston rod and the piston cylinder will adsorb the bottom of the appliance through the connecting tube, the cavity and the short tube in the through hole, and cooperate with the rubber anti-skid pad matched with the top of the appliance to achieve a stable adsorption effect on the top of the appliance. Since the rubber anti-skid pad is made of rubber material, when the appliance and the rubber anti-skid pad move relative to each other, the deformation of the rubber anti-skid pad will cause the overflowed soft rubber to fill the gap at the top of the appliance, thereby improving the sealing of the negative pressure suction between the two and enhancing the stability of the appliance when it is attracted.

[0020] 4. By setting up a clamping mechanism, the two piston blocks will approach each other under negative pressure, and the clamping block will be pulled closer to the connecting block through the connecting shaft, so as to achieve corresponding clamping of the two sides of the appliance, further improving the stability of the appliance during flexible adsorption, and avoiding the appliance from falling off due to vibration during subsequent processing. When the two clamping blocks are close, the two ends of the rubber anti-slip pad will be squeezed by the two clamping blocks, and the two sides of the appliance will be fitted, which also further improves the sealing between the rubber anti-slip pad and the appliance;

[0021] 5. By setting up an anti-slip mechanism, when the two clamping blocks are close to each other, one end of the first piston shaft is pushed back into the air guide cavity. At this time, the air pressure in the air guide cavity increases, thereby pushing the bottom end of the second piston shaft out of the clamping block and squeezing the L-shaped block to deflect at a certain angle. At this time, the other end of the L-shaped block will push the bottom of the orthodontic appliance upward, so that a closer fit is formed between the top of the orthodontic appliance and the rubber anti-slip pad, thereby further improving the air tightness between the two, and achieving a fully encircling clamping and grasping effect on the orthodontic appliance;

[0022] 6. By setting up an alarm mechanism and utilizing the linkage between the pressure sensor and the clamping mechanism, when the two clamping blocks and the connecting block are fitted, the rubber abutment block will squeeze the pressure sensor. At this time, the dual-color alarm light is poorly lit. When the clamping block on one side accidentally becomes loose, resulting in the inability to form a stable abutment relationship between the pressure sensor and the rubber abutment block, the color light area on one side of the dual-color alarm light lights up, making it easy for users to immediately find the problem location, and then remind maintenance personnel to quickly repair it, thereby improving the practicality and intelligent effect of the equipment.

Through the above arrangement, the feeding mechanism 10 and the receiving mechanism 11 can be used to realize automatic loading of the orthodontic appliance and automatic recovery of the tray 8. Through the flexible adsorption mechanism 12, the clamping mechanism 13 and the anti-slipping mechanism 14, a multi-angle flexible adsorption and clamping effect is achieved. While ensuring flexible adsorption, the stability of the orthodontic appliance during processing is improved. The setting of the alarm mechanism 15 can accurately display the problem location when the flexible adsorption mechanism 12, the clamping mechanism 13 and the anti-slipping mechanism 14 are loose, so as to facilitate maintenance personnel to quickly repair.

[0044] like Figure 3 As shown, the top of the tray 8 is provided with a plurality of placement grooves 801 for placing the braces, and the outer sides of the placement grooves 801 are provided with a plurality of clamping shafts 802 for clamping the braces. Through the above arrangement, the user can conveniently place a plurality of braces on a tray 8 when loading and complete the clamping, thereby achieving the effect of simultaneous processing and polishing of a plurality of braces, which greatly improves the processing efficiency of the braces.

[0045] like Figure 3 As shown, the feeding mechanism 10 includes a fixed seat 101, which is arranged in the equipment body 1 and is located directly below the processing area 3. A rectangular through groove is opened on the processing area 3 corresponding to the fixed seat 101, and the four corners of the fixed seat 101 are all slidably connected with a sliding limit rod 102, and the top ends of multiple sliding limit rods 102 are commonly fixedly connected with a support plate 103. A plurality of vertically arranged trays 8 are provided on the top of the support plate 103. Through the above arrangement, the trays 8 can be placed in advance conveniently. When the multiple trays 8 are located directly below the rectangular through groove, under the transmission of the feeding mechanism 10, stable indirect feeding will be carried out, without the need for manual continuous feeding, thereby improving processing efficiency.

[0046] like Fig. 9 As shown, a threaded ring 104 is embedded and rotatably connected at the center of the fixing seat 101, a threaded rod 105 is connected to the inner thread of the threaded ring 104, and the top of the threaded rod 105 is fixedly connected to the bottom of the support plate 103, and the bottom end of the threaded ring 104 is fixedly connected to a main gear 106, and the main gear 106 is meshedly connected to a secondary gear 107, and the bottom of the fixing seat 101 is fixedly connected to a mounting frame 109, and a motor 108 is fixedly installed on the mounting frame 109, and the top of the output shaft of the motor 108 is fixedly connected to the center of the secondary gear 107. By starting the motor 108, the electric The output shaft of the machine 108 drives the secondary gear 107 to rotate simultaneously by rotating, thereby driving the main gear 106 and the threaded ring 104 to rotate. When the threaded ring 104 rotates, the threaded rod 105 connected with the thread will push the support plate 103 to move upward when the support plate 103 is limited by the sliding limit rod 102. By adjusting the switch and rotation frequency of the motor 108, it is possible to achieve indirect automatic lifting and feeding of multiple trays 8, so that each tray of orthodontic appliances continues to appear in the processing area 3, which is convenient for the subsequent grabbing of the orthodontic appliances and improves the processing efficiency.

[0047] like Figure 2 and Figure 8 As shown, the material receiving mechanism 11 includes a first electric push rod 1101 and a material guide box 1102. The first electric push rod 1101 is fixedly installed on the processing area 3, and the end of the output shaft is close to the rectangular through groove. The material guide box 1102 is located directly below the bottom end of the equipment body 1 and is provided with a material receiving box 1103 for conveniently receiving the tray 8, and the outer side of the material receiving box 1103 is provided with a handle for convenient grasping. Through the setting of the material receiving mechanism 11, it can be achieved that all the orthodontic appliances in the tray 8 are grasped and left the processing area 3, and the first electric push rod 1101 is started, so that the output shaft of the first electric push rod 1101 extends, and the tray 8 is pushed into the material guide box 1102, and slides into the material receiving box 1103 for centralized collection, which is convenient for personnel to take and re-load the orthodontic appliances, further improving the efficiency of material input and output of the processing equipment.

[0048] like Figure 4 , Fig.10 and Fig.11As shown, the flexible adsorption mechanism 12 includes a second electric push rod 1201, which is fixedly connected to the bottom of the moving block on the electric slide rail 9, and the output shaft of the second electric push rod 1201 is fixedly connected to a connecting plate 1211, and the end of the second electric push rod 1201 away from the output shaft is fixedly connected to a fixed plate 1202 in a through-type manner, and a plurality of piston rods 1203 and piston cylinders 1204 are fixedly connected between the fixed plate 1202 and the connecting plate 1211, and the piston rods 1203 are piston-connected with the corresponding piston cylinders 1204, and the bottom end of the piston cylinder 1204 is plugged with an air guide tube 1205, and the end of the air guide tube 1205 away from the piston cylinder 1204 is plugged with a connecting tube 1206 , and is equipped with a solenoid valve. Through this setting, the moving block of the electric slide rail 9 can be controlled to move accurately to the top of the tray 8, and then the output shaft of the second electric push rod 1201 is controlled to rise and fall, driving the flexible adsorption mechanism 12 at the bottom end of the output shaft to move closer to the orthodontic device, thereby achieving accurate grasping of the orthodontic device. During this period, the air in the piston rod 1203 and the piston cylinder 1204 forms a negative pressure when the piston cylinder 1204 moves downward following the connecting plate 1211, and the air guide tube 1205 plugged into the piston cylinder 1204 can release and maintain the negative pressure by controlling the solenoid valve installed on itself, so that the flexible adsorption mechanism 12 can achieve the flexible adsorption and grasping action of the orthodontic device.

[0049] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10As shown, the bottom end of the connecting tube 1206 is fixedly connected to the connecting plate 1211 in a through-type manner, and the bottom ends of the multiple connecting tubes 1206 that pass through the connecting plate 1211 are fixedly connected to a connecting block 1207, a cavity is provided in the connecting block 1207, and a rubber anti-skid pad 1209 that matches the top of the orthodontic appliance is fixedly connected to the bottom of the connecting block 1207, and a through hole is provided in the center of the rubber anti-skid pad 1209, and the cavities are respectively connected to the connecting tubes 1206 and the rubber anti-skid pad 1209. The through holes are connected, and a short tube 1208 is slidably connected to the bottom of the cavity. The short tube 1208 is fixedly connected in the through hole. A plurality of spherical rubber bumps 1210 are arranged at the bottom of the rubber anti-skid pad 1209.

Stable adsorption effect. When the orthodontic appliance is attracted by negative pressure and squeezes the bottom of the rubber anti-skid pad 1209 under strong negative pressure, the rubber anti-skid pad 1209 is made of rubber material and the deformation of the rubber anti-skid pad 1209 will cause the overflowing soft rubber to fill the gap at the top of the orthodontic appliance, thereby improving the sealing of the negative pressure attraction between the two and enhancing the stability of the orthodontic appliance when attracted. The setting of the short tube 1208 can keep the through hole unobstructed during squeezing. Through the setting of multiple spherical rubber bumps 1210, when the bottom of the rubber anti-skid pad 1209 is squeezed at the top of the orthodontic appliance, multiple smaller spherical rubber bumps 1210 can more easily fill the gap at the top of the orthodontic appliance. Compared with traditional direct adsorption, the rubber material and shape of the rubber anti-skid pad 1209 and the spherical rubber bumps 1210 can better cooperate with negative pressure attraction to form a more stable flexible adsorption and grasping effect on the top of the orthodontic appliance.

[0050] like Figure 7 and Figure 8As shown, the clamping mechanism 13 includes two piston blocks 1301, and the two piston blocks 1301 are respectively connected to the inner wall pistons at both ends of the cavity, and the opposite sides of the two piston blocks 1301 are fixedly connected with a connecting shaft 1302, and a sealing sleeve 1303 is sleeved on the connecting shaft 1302, and the sealing sleeve 1303 is connected to the connecting shaft 1302 piston, and the sealing sleeve 1303 is fixedly connected to the inner wall of the cavity, and the end of the connecting shaft 1302 away from the piston block 1301 passes through the connecting block 1207 and is fixedly connected with a clamping block 1304. Exhaust holes are provided on the inner walls of the two ends of the cavity relative to the piston blocks 1301. Through the above arrangement, when negative pressure appears in the cavity, as the flexible adsorption mechanism 12 flexibly adsorbs the top of the orthodontic appliance, the clamping mechanism 13 is also The two piston blocks 1301 will approach each other under negative pressure, and pull the clamping block 1304 toward the connecting block 1207 through the connecting shaft 1302. As the two clamping blocks 1304 approach, the two sides of the appliance will be clamped accordingly, thereby further improving the stability of the flexible adsorption of the appliance and avoiding the appliance from falling off due to vibration during subsequent processing. When the two clamping blocks 1304 approach, the two ends of the rubber anti-slip pad 1209 will be squeezed by the two clamping blocks 1304 and fit the two sides of the appliance, which further improves the sealing between the rubber anti-slip pad 1209 and the appliance, and further enhances the stability of the flexible adsorption of the appliance. The exhaust hole can facilitate the piston movement of the piston block 1301 in the cavity.

[0051] like Figure 6 , Figure 7 and Figure 8As shown, the anti-slip mechanism 14 includes an air guide cavity 1401, which is opened in the clamping block 1304. The upper and lower ends of the air guide cavity 1401 are piston-connected with a first piston shaft 1402 and a second piston shaft 1403 respectively. One end of the first piston shaft 1402 is located outside the air guide cavity 1401. The bottom ends of the two sealing sleeves 1303 are rotatably connected with an L-shaped clamping block 1404. The bottom end of the second piston shaft 1403 penetrates the sealing sleeve 1303 and is located on one side of the top of the L-shaped clamping block 1404. A spring wire 1405 is fixedly connected between the top of the L-shaped clamping block 1404 and the bottom end of the clamping block 1304. Through the above arrangement, when the two clamping blocks 1304 are attracted to each other by negative pressure, the first piston shaft outside the clamping block 1304 will be pulled closer to each other. One end of 1402 is pushed back into the air guide cavity 1401. At this time, the air pressure in the air guide cavity 1401 increases, thereby pushing the bottom end of the second piston shaft 1403 out of the clamping block 1304, and squeezing the L-shaped block 1404 to deflect at a certain angle. At this time, the other end of the L-shaped block 1404 will push the bottom of the orthodontic appliance upward, so that a closer fit is formed between the top of the orthodontic appliance and the rubber anti-slip pad 1209, thereby further improving the air tightness between the two and ensuring that when negative pressure is formed in the cavity, the flexible adsorption mechanism 12 can stably and flexibly adsorb the orthodontic appliance, and cooperate with the clamping mechanism 13 to achieve a comprehensive surrounding clamping and grasping effect on the orthodontic appliance, thereby improving the stability of the orthodontic appliance during the grinding process and avoiding the problem of the orthodontic appliance being easily shaken and falling off.

[0052] like Figure 6 , Figure 7 and Figure 8 As shown, the alarm mechanism 15 includes a pressure sensor 1501, and there are two pressure sensors 1501. The two pressure sensors 1501 are fixedly connected to the two ends of the top of the two connecting blocks 1207 respectively. The tops of the two clamping blocks 1304 are fixedly connected with rubber abutment blocks 1502 adapted to the pressure sensors 1501. A two-color alarm light 1503 is fixedly installed on one side of the connecting block 1207. The two-color alarm light 1503 is provided with a two-color light area. Through the above arrangement, it can be achieved that the two clamping blocks 1304 and the When the connecting block 1207 is fitted, the rubber abutment block 1502 will squeeze the pressure sensor 1501. At this time, the two-color warning light 1503 will not light up. When the clamping block 1304 on one side accidentally loosens, resulting in the inability to form a stable abutment relationship between the pressure sensor 1501 and the rubber abutment block 1502, the color light area on the corresponding side of the two-color warning light 1503 will light up, making it easy for users to immediately find the problem location, and then remind maintenance personnel to quickly repair it, thereby improving the practicality and intelligent effect of the equipment.

[0053] Working principle:

[0054] First, the moving block of the electric slide rail 9 is controlled to move precisely to the top of the tray 8, and then the output shaft of the second electric push rod 1201 is controlled to move up and down, driving the flexible adsorption mechanism 12 at the bottom of the output shaft to move closer to the appliance, thereby achieving precise grasping of the appliance;

[0055] During this period, the air in the piston rod 1203 and the piston cylinder 1204 forms a negative pressure when the piston cylinder 1204 moves downward following the connecting plate 1211, and the air guide tube 1205 inserted in the piston cylinder 1204 can release and maintain the negative pressure by controlling the solenoid valve installed on itself, so as to facilitate the flexible adsorption mechanism 12 to achieve the flexible adsorption and grasping action of the orthodontic device. When the solenoid valve is opened, the negative pressure in the piston rod 1203 and the piston cylinder 1204 will adsorb the bottom of the orthodontic device through the connecting tube 1206, the cavity and the short tube 1208 in the through hole, and cooperate with the rubber anti-skid pad 1209 matched with the top of the orthodontic device to achieve a stable adsorption effect on the top of the orthodontic device. When the orthodontic device is attracted by the negative pressure and squeezed on the bottom of the rubber anti-skid pad 1209 under the strong negative pressure, the rubber anti-skid pad 1209 will be used for the suction of the orthodontic device. The pad 1209 is made of rubber material, so the deformation of the rubber anti-skid pad 1209 will make the overflowed soft rubber fill the gap at the top of the appliance, improve the sealing of the negative pressure suction between the two, and enhance the stability of the appliance when being sucked. The setting of the short tube 1208 can keep the through hole in a continuous unobstructed state during squeezing. Through the setting of multiple spherical rubber bumps 1210, when the bottom of the rubber anti-skid pad 1209 is squeezed at the top of the appliance, multiple smaller spherical rubber bumps 1210 can more easily fill the gap at the top of the appliance. Compared with traditional direct adsorption, the rubber material and shape of the rubber anti-skid pad 1209 and the spherical rubber bumps 1210 can better cooperate with negative pressure suction to form a more stable flexible adsorption and grasping effect on the top of the appliance.

[0056] Furthermore, when negative pressure appears in the cavity, as the flexible adsorption mechanism 12 flexibly adsorbs the top of the appliance, the two piston blocks 1301 in the clamping mechanism 13 will approach each other under the negative pressure, and pull the clamping block 1304 toward the connecting block 1207 through the connecting shaft 1302. As the two clamping blocks 1304 approach, the two sides of the appliance will be clamped accordingly, thereby further improving the stability of the appliance during flexible adsorption and preventing the appliance from falling off due to vibration during subsequent processing. When the two clamping blocks 1304 approach, the two ends of the rubber anti-skid pad 1209 will be squeezed by the two clamping blocks 1304 and fit the two sides of the appliance, further improving the sealing between the rubber anti-skid pad 1209 and the appliance.

[0057] Furthermore, when the two clamping blocks 1304 are attracted to each other by the negative pressure, one end of the first piston shaft 1402 outside the clamping block 1304 will be pushed back into the air guide chamber 1401. At this time, the air pressure in the air guide chamber 1401 increases, thereby pushing the bottom end of the second piston shaft 1403 out of the clamping block 1304 and squeezing the L-shaped block 1404 to deflect at a certain angle. At this time, the other end of the L-shaped block 1404 will push the bottom of the orthodontic appliance upward, so that a closer fitting relationship is formed between the top of the orthodontic appliance and the rubber anti-slip pad 1209, thereby further improving the air tightness between the two, ensuring that when negative pressure is formed in the cavity, the flexible adsorption mechanism 12 can stably and flexibly adsorb the orthodontic appliance, and cooperate with the clamping mechanism 13 to achieve a fully surrounding clamping and grasping effect on the orthodontic appliance, thereby improving the stability of the orthodontic appliance during the grinding process and avoiding the problem of the orthodontic appliance being easily shaken and falling off;

[0058] In addition, when the two clamping blocks 1304 and the connecting block 1207 are fitted, the rubber abutment block 1502 will squeeze the pressure sensor 1501. At this time, the light of the two-color alarm light 1503 is poor. When the clamping block 1304 on one side is accidentally loosened, resulting in the inability to form a stable abutment relationship between the pressure sensor 1501 and the rubber abutment block 1502, the color light area on the corresponding side of the two-color alarm light 1503 lights up, which is convenient for users to immediately find the problem location, and then remind maintenance personnel to quickly repair it, thereby improving the practicality and intelligent effect of the equipment;

[0059] It is worth mentioning that by starting the motor 108 in the feeding mechanism 10, the output shaft of the motor 108 drives the secondary gear 107 to rotate simultaneously, thereby driving the main gear 106 and the threaded ring 104 to rotate. When the threaded ring 104 rotates, the threaded rod 105 connected with the thread will push the support plate 103 to move upward when the support plate 103 is limited by the sliding limit rod 102. By adjusting the switch and rotation frequency of the motor 108, it is possible to achieve indirect automatic lifting and feeding of multiple trays 8. , to ensure that each tray of braces continues to appear in the processing area 3, which is convenient for the subsequent grabbing of the braces and improves the processing efficiency. When all the braces in the tray 8 are grabbed and leave the processing area 3, the first electric push rod 1101 in the material receiving mechanism 11 is started, so that the tray 8 is pushed into the material guide box 1102 through the extension of the output shaft of the first electric push rod 1101, and slides into the material receiving box 1103 for centralized collection, which is convenient for personnel to take and re-load the braces, further improving the efficiency of the processing equipment in and out of the material.
