The weight sensor 8 is provided with a strain gauge, a spring body, a conversion unit, a measuring unit and a signal processing circuit. Based on the strain measurement principle, when a device is placed on the storage plate 1, the spring body is deformed by an external force, and the strain gauge attached to the spring body is deformed accordingly. The resistance value of the strain gauge increases when it is stretched, and decreases when it is compressed. The conversion unit and the measuring unit convert the resistance value change of the strain gauge into an electrical signal, and the electrical signal is amplified and filtered by the signal processing circuit. After being processed, it is converted into a weight signal. After the controller 3 receives the weight signal transmitted by the weight sensor 8, it is determined that there is an object placed on the storage plate 1. The sensing unit 9 sends an infrared beam through the infrared transmitter 43. The infrared receiver 44 receives the signal when the beam is not blocked. Non-contact measurement is performed using infrared technology. When the medical staff places and takes the equipment, the beam is blocked and the infrared receiver 44 cannot receive the signal. The controller 3 determines whether the medical staff leaves the storage plate 1 after taking and placing the equipment through the change of the signal received by the sensing unit 9. 43 and the rotating shaft 45 below the infrared receiver 44 rotate synchronously to expand the detection range. At the same time, through the information collection of the weight sensor 8, it is determined whether the medical staff is taking or placing the equipment. After placing the equipment, the controller 3 controls the fixed motor 12 to drive the rotating gear 11 to push the first push rod 10 to drive the clamping plate 7 to move, so as to fix the equipment placed on the placement plate 1. After the fixation is completed, the connection between the rotating gear 11 and the first push rod 10 is disconnected through the adapter 15, and the shaking causes the fixing effect to be weakened. When the medical staff needs to take the equipment placed on the placement plate 1, the connection between the rotating gear 11 and the first push rod 10 is restored through the adapter 15, and the clamping plate 7 used to fix the equipment is moved back to the original position through the first push rod 10, so as to realize the function of fixing the dental scanner, solve the problems of equipment slipping and damage, equipment wear and medical staff negligence, reduce the risk of human operation errors, improve operation efficiency, extend the service life of the equipment, meet the needs of temporary placement of the equipment, and ensure that the problems of reduced scanning accuracy and increased patient discomfort caused by shaking during use will not occur during the scanning process.

[0022] Example 2: Please refer to Figure 1 , Figure 2 and Figure 4 A special stable cart for dental scanners, wherein the storage compartment 4 is provided with wheels 2 on the lower side of the outer wall, the wheels 2 are connected to a stationary motor 21 through a connecting shaft, and a stationary component 17 is provided on the upper side of the outer wall of the wheels 2, and the stationary component 17 is connected to a controller 3 through a signal line; The stationary component 17 includes: a wheel speed sensor 18, a fixing plate 19, a lifting rod 20 and a stationary motor 21, and the lifting rod 20 is connected to the stationary motor 21 through a connecting shaft; A wheel speed sensor 18 is installed on the upper side of the outer wall of the wheel 2, a fixing plate 19 is installed on the upper side of the outer wall of the wheel 2, a lifting rod 20 is installed on the upper side of the outer wall of the fixing plate 19, and a stationary motor 21 is installed on the lower side of the outer wall of the storage compartment 4; Furthermore, the wheel speed sensor 18 is internally provided with a permanent magnet, a polar axis, an induction coil, a gear ring and a processing circuit. Based on the principle of electromagnetic induction, when the cart is pushed, the gear ring installed on the wheel 2 rotates with the wheel 2, and the teeth and gaps of the gear ring pass through the sensor magnetic field in sequence and quickly, changing the magnetic resistance of the magnetic circuit, causing the induced electromotive force in the induction coil to change, generating an electromotive force pulse, and the generated pulse frequency reflects the rotation speed of the wheel 2. The controller 3 determines whether the cart is in a stationary state by receiving the information transmitted by the wheel speed sensor 18. When the cart is in a stationary state, the controller 3 uses the stationary electromotive force to generate an electric potential pulse. The machine 21 drives the lifting rod 20 to push the fixing plate 19 downward until it is in contact with the ground, thereby isolating the wheel 2. When the cart needs to be moved, the operator issues a command through the controller 3, and the static motor 21 drives the lifting rod 20 to lift the fixing plate 19, contacting the isolation restriction on the wheel 2, thereby realizing the function of isolating the wheel 2, solving the problem of sliding and shaking caused by sliding of the wheel 2 due to environmental factors after the wheel 2 is fixed, and can ensure that the wheel 2 is in a fixed state when the cart is stationary, and will not affect the cart and the equipment on the cart, thereby improving the stability and safety of the cart.

[0023] Example 3: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 8 , a special stable cart for dental scanner, a drying component 22 is installed on the right side of the outer wall of the storage compartment 4, and the drying component 22 is connected to the controller 3 through a signal line; The drying assembly 22 includes: a visual sensor 23, a fan 24, a drying motor 25 and a heating wire 26.

Different types of scanning positioning parts and dental scanners are adapted to different drying temperatures and drying times. Scanning positioning parts made of heat-sensitive materials are prone to deformation or aging at high temperatures. Too low a drying temperature may cause alcohol residue, which will not only affect the cleanliness of the equipment, but also become a breeding ground for bacteria. The drying component 22 collects information about the equipment that needs to be dried through the visual sensor 23, and transmits the information to the controller 3 to identify the type of equipment, drying temperature and drying time. After identifying the type of equipment, the controller 3 controls the heating wire 26 to heat up. The drying motor 25 drives the fan 24 to rotate and blow out hot air to dry the equipment. When medical staff need to dry their hands or other parts, the controller 3 releases the fixing effect of the fixer 51 on the inner ring 48, and drives the pulley 50 to rotate through the lifting motor 49 to adjust the height of the inner ring 48. After reaching the specified height, the fixer 51 resumes the fixing effect on the inner ring 48, realizing the function of intelligent drying, solving the problem of equipment damage and poor drying effect caused by drying at the same temperature, and being able to identify different types of equipment to select appropriate drying temperature and drying time, thereby improving the cleanliness of the equipment, ensuring the disinfection effect of the equipment, and extending the service life of the equipment.

After emptying, the liquid storage box 5 and the replacement port 31 are connected through the water valve 28, and the clean water and cleaning liquid stored in the liquid storage box 5 are transported to the inside of the storage compartment 4 in turn through the pressurizing unit 29, and rinsed by high-pressure water flow. After rinsing, the waste liquid The replacement port 31 and the collection box 6 are connected through the water valve 28 and discharged into the collection box 6, and the storage compartment 4 is air-dried. After drying, the 75% alcohol stored in the liquid storage box 5 is added to the storage compartment 4 through the replacement port 31, and the disinfection function of the storage compartment 4 is restored, realizing the automatic cleaning function of the disinfection area, solving the problems of reduced disinfection effect, damaged equipment performance and increased infection risk caused by failure to replace the disinfectant in time, ensuring that the disinfection can achieve the expected effect, avoiding cross infection, ensuring the health and safety of patients, reducing the corrosion of the disinfectant to the equipment, and extending the service life of the equipment.

[0025] Example 5: Please refer to Figure 1 , Figure 2 and Figure 3 , a special stable cart for dental scanner, the fixing assembly further comprises a magnetic module 13, the magnetic module 13 is connected to the controller 3 via a signal line; The magnetic module 13 includes: a storage compartment 4, a second push rod 14, a transfer interface 15 and a suction cup 16, and the second push rod 14 is connected to the rotating gear 11 through the transfer interface 15; A storage compartment 4 is installed on the lower side of the outer wall of the storage plate 1, a suction cup 16 is installed on the lower side of the outer wall of the storage compartment 4, a second push rod 14 is installed on the right side of the outer wall of the storage compartment 4, and a transfer interface 15 is installed on the lower side of the outer wall of the rotating gear 11; The suction cup 16 includes: an electromagnet 32 ​​and a magnetoresistive sensor 33, the electromagnet 32 ​​and the magnetoresistive sensor 33 are connected to the controller 3 through a signal line, and the electromagnet 32 ​​is connected to the power supply 27 through a signal line; An electromagnet 32 ​​is installed on the lower side of the outer wall of the storage compartment 4, a magnetic resistance sensor 33 is installed on the lower side of the outer wall of the electromagnet 32, and a power supply 27 is installed on the lower side of the outer wall of the storage plate 1; Furthermore, when the medical staff uses the dental scanner to scan the patient's oral cavity, when the patient's oral condition is more complicated, such as a large number of missing teeth or irregular arrangement, it is difficult for a single scanner to accurately position, and it is necessary to use a scanning positioning piece to assist the dental scanner in scanning to obtain a more accurate three-dimensional image of the oral cavity. At this time, the medical staff selects a scanning positioning piece suitable for the patient through the controller 3. After the controller 3 receives the signal, the controller 3 disconnects the connection between the electromagnet 32 ​​and the power supply 27 to release the magnetic attraction of the suction cup 16 on the storage compartment 4, and detects it through the magnetoresistive sensor 33. The magnetoresistive sensor 33 is internally provided with a magnetic sensitive element, a dynamic zeroing circuit and a signal processing circuit. Based on the magnetoresistive effect, when the magnetic field acts on the magnetic sensitive element, the resistance of the magnetic sensitive element will change. The resistance change of the magnetic sensitive element is amplified, filtered and converted by the signal processing circuit, and the resistance change is converted into a voltage or current signal. The change in resistance of the magnetic sensitive element is detected to determine whether the suction cup 16 cancels the magnetic attraction of the storage compartment 4, and the adapter 15 is connected to the second push rod 14. The second push rod 14 is driven by the fixed motor 12 to push the storage compartment 4 containing the scanning positioning part out of the body 1. After the medical staff takes out the scanning positioning part, the weight sensor 8 senses that the weight in the storage compartment 4 has decreased. After 5 seconds, the controller 3 controls the second push rod 14 to pull the storage compartment 4 back. At the same time, the suction cup 16 resumes the magnetic attraction to the storage compartment 4, and releases the magnetic attraction to the storage compartment 4 storing the disinfectant. The storage compartment 4 is pushed out by the second push rod 14. The medical staff puts the scanning positioning part into the storage compartment 4 filled with disinfectant that is 70% alcohol, disinfects it for 30 minutes, and then takes it out. After drying, the scanning positioning part is placed in the patient's mouth, and the dental scanner is soaked in the disinfectant for 30 minutes and then dried. After completing the disinfection and drying treatment, the medical staff uses the dental scanner to collect information from the patient's mouth, realizing the function of intelligent preparation work, solving the problem of forgetting to close and easy opening of the drawer-type storage compartment 4 during work, which can reduce the work fatigue of the medical staff, improve the working accuracy and efficiency of the dental scanner, and reduce the occurrence of medical accidents.

[0026] Working principle: the controller 3 determines whether the cart is in a stationary state by receiving the information transmitted by the wheel speed sensor 18. When the cart is in a stationary state, the controller 3 drives the lifting rod 20 through the stationary motor 21 to push the fixed plate 19 downward until it is in contact with the ground, thereby isolating the wheel 2. When the cart needs to be moved, the operator issues an instruction through the controller 3, and the stationary motor 21 drives the lifting rod 20 to raise the fixed plate 19, contacting the isolation limit of the wheel 2, thereby realizing the function of isolating the wheel 2. The controller 3 selects a scanning positioning piece suitable for the patient. After receiving the signal, the controller 3 disconnects the connection between the electromagnet 32 ​​and the power supply 27 to release the magnetic attraction of the suction cup to the storage compartment 4. The magnetic resistance sensor 33 is used to detect whether the suction cup 16 cancels the magnetic attraction of the storage compartment 4. The adapter 15 is connected to the second push rod 14. The second push rod 14 is driven by the fixed motor 12 to push the storage compartment 4 containing the scanning positioning piece out of the body 1. After the medical staff takes out the scanning positioning piece, the weight sensor 8 senses that the weight in the storage compartment 4 is reduced. After 5 seconds, the controller 3 controls the second push rod 14 to pull the storage compartment 4 back. At the same time, the suction cup 16 resumes the magnetic attraction of the storage compartment 4, and releases the magnetic attraction of the storage compartment 4 storing the disinfectant. The storage compartment 4 is pushed out by the second push rod 14. The medical staff puts the scanning positioning piece into the storage compartment 4 containing the disinfectant, which is 70% alcohol, and disinfects it for 30 minutes before taking it out. The dental scanner is soaked in the disinfectant for 30 minutes. The scanning positioning parts and dental scanners that have been disinfected by immersion in 75% alcohol need to be dried before they can enter the patient's mouth. The drying component 22 collects information about the equipment that needs to be dried through the visual sensor 23, and transmits the information to the controller 3 to identify the type of equipment, drying temperature and drying time. After identifying the type of equipment, the controller 3 controls the heating wire 26 to heat up, and the drying motor 25 drives the fan 24 to rotate to blow out hot air to dry the equipment. When medical staff need to dry their hands or other parts, the controller 3 releases the fixing effect of the fixer 51 on the inner ring 48, and drives the pulley 50 to rotate through the lifting motor 49 to adjust the height of the inner ring 48. After reaching the specified height, the fixer 51 resumes the fixing effect on the inner ring 48. After the immersion disinfection is completed, the controller 3 controls the second push rod 14 to pull back the storage compartment 4 storing the disinfectant, the suction cup 16 resumes the magnetic attraction to the storage compartment 4, the water valve 28 connects the replacement port 31 and the collection box 6, and the contaminated disinfectant in the storage compartment 4 is discharged from the replacement port 31 into the collection box 6. After emptying, the liquid storage box 5 and the replacement port 31 are connected through the water valve 28, and the clean water and cleaning liquid stored in the liquid storage box 5 are transported to the inside of the storage compartment 4 in sequence through the pressurizing unit 29, and flushed by high-pressure water flow. After flushing, the waste liquid is connected to the replacement port 31 and the collection box 6 through the water valve 28 and discharged into the collection box 6, and the storage compartment 4 is air-dried. After drying, the 75% alcohol stored in the liquid storage box 5 is added to the storage compartment 4 through the replacement port 31 to restore the disinfection function of the storage compartment 4. The weight sensor 8 is used to sense whether there is equipment placed on the cart storage plate 1. After the controller 3 receives the weight signal transmitted by the weight sensor 8, it is determined that there is an object placed on the storage plate 1. The sensing unit 9 sends an infrared beam through the infrared transmitter 43. The infrared receiver 44 receives the signal when the beam is not blocked. Non-contact measurement is performed using infrared technology. When the medical staff places and takes the equipment, the beam is blocked and the infrared receiver 44 cannot receive the signal. The controller 3 determines whether the medical staff leaves the storage plate 1 after taking and placing the equipment through the change of the signal received by the sensing unit 9. The infrared transmitter 43 and the infrared receiver 44 are connected by the rotating shaft 45 installed below the infrared transmitter 43 and the infrared receiver 44. The synchronous rotation expands the detection range, and at the same time, the information collected by the weight sensor 8 is used to determine whether the medical staff is taking or placing the equipment. After placing the equipment, the controller 3 controls the fixed motor 12 to drive the rotating gear 11 to push the first push rod 10 to drive the splint 7 to move, so as to fix the equipment placed on the placement plate 1. After the fixation is completed, the connection between the rotating gear 11 and the first push rod 10 is disconnected through the adapter 15, and the shaking causes the fixing effect to be weakened. When the medical staff needs to take the equipment placed on the placement plate 1, the connection between the rotating gear 11 and the first push rod 10 is restored through the adapter 15, and the splint 7 used to fix the equipment is moved back to its original position through the first push rod 10.
