Description

Technical Field

[0001] This utility model relates to the field of sample measurement technology, and in particular to an automated multi-sample measurement device. Background Technology

[0002] During the production of dental mold orthodontic appliances, orthodontic appliance samples are made by thermoforming on 3D printed dental molds. Each sample is then measured using a sample measuring device to ensure stable production.

[0003] However, existing sample measurement devices can usually only measure one sample at a time, which is inefficient and not convenient for measuring a large number of samples, making them inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an automated multi-sample measurement device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an automated multi-sample measurement device, including a measurement conveying platform for transporting samples. A rotating measuring seat for rotation adjustment is fixedly installed in the middle of the measurement conveying platform. A sample mold for lifting adjustment is fixedly installed at the top of the rotating measuring seat. Measurement fixtures for sample detection are fixedly installed at both ends of the sample mold. The measurement fixtures are signal-connected to a central control unit for automated control. The central control unit is signal-connected to several laser rangefinders for detecting sample dimensions. A proximity switch for detecting the start and stop of rotation is arranged around the circumference of the rotating measuring seat. An isolation protective plate for inductive isolation is arranged on one side of the proximity switch. A positioning sensor for detecting sample position is arranged on one side of the isolation protective plate.

[0006] Preferably, the top of the measuring conveyor is provided with a groove for fixing the rotating measuring seat, and a sensing metal plate that senses the proximity switch is provided around the circumference of the groove. The sensing metal plate is fixedly installed inside the measuring conveyor.

[0007] The above technical solution is adopted: the groove at the top of the measuring conveyor is precisely adapted to the rotating measuring seat, providing it with a stable installation position and ensuring that the rotating measuring seat will not deviate during rotation. The sensing metal plate on the circumference of the groove works in conjunction with the proximity switch. When the rotating measuring seat rotates, the proximity switch can accurately detect the position of the rotating measuring seat through the sensing metal plate, thereby realizing precise control of the rotation start and stop of the rotating measuring seat, and ensuring the orderly progress of the entire measurement process.

[0008] Preferably, in any of the above embodiments, the rotating measuring base includes a rotating motor connected to a central control unit and a rotating base for supporting and positioning the sample. The rotating motor is fixedly installed inside the measuring conveyor stage, and the output end of the rotating motor is fixedly installed with a rotating base that rotates inside the measuring conveyor stage.

[0009] The above technical solution is adopted: the rotary motor of the rotary measuring seat is controlled by the central control unit and installed inside the measuring conveyor. After starting, the rotary motor drives the rotary seat to rotate inside the measuring conveyor, so that the sample mold and measuring fixture can reach the measuring position in sequence. The rotary seat not only supports the sample mold, but also provides a mounting position for components such as laser rangefinder and proximity switch, ensuring that the components work together to realize continuous measurement of multiple samples.

[0010] Preferably, in any of the above embodiments, the sample mold includes a pneumatic telescopic rod connected to a central control unit and a measuring mold base for locking and positioning the sample. The pneumatic telescopic rod is fixedly installed on the top of the rotating base, and the measuring mold base is fixedly installed on the top of the pneumatic telescopic rod.

[0011] The above technical solution is adopted: the pneumatic telescopic rod of the sample mold is controlled by the central control unit and installed on the top of the rotating seat. When it is necessary to adjust the sample height, the pneumatic telescopic rod extends or shortens, driving the measuring mold base to rise and fall, so that the sample is in a suitable measuring position. The measuring mold base is used to lock and position the sample, ensuring that the sample position is fixed during the measurement process and improving the accuracy of the measurement.

[0012] Preferably, according to any of the above embodiments, the measuring fixture includes a measuring cylinder connected to a central control unit, a measuring clamping head, a pressure sensor for pressure detection, and a measuring head for bearing pressure.

The pressure sensor connected to the central control unit is fixedly installed inside the measuring clamping head. The measuring head located inside the measuring clamping head is fixedly installed at the detection end of the pressure sensor. A positioning sensor for detecting the measuring distance is fixedly installed at one end of the measuring clamping head.

[0013] The above technical solution employs the following: The measuring cylinder of the measuring fixture is controlled by a central control unit and installed at both ends of the measuring mold base. When the measuring cylinder is activated, its output end pushes the measuring clamping head to clamp the sample. The pressure sensor can monitor the clamping pressure in real time and transmit the data to the central control unit. The central control unit adjusts the working state of the measuring cylinder according to the pressure data to ensure that the clamping force is moderate and to avoid sample damage or insecure clamping. The measuring pressure head is in direct contact with the sample. With the cooperation of the pressure sensor, stable clamping and pressure monitoring of the sample are achieved. At the same time as the measuring pressure head detects the pressure value, the positioning sensor synchronously detects the movement distance of the measuring clamping head. When the measuring clamping head moves 0.5mm ± 0.02mm, the initial clamping force on the fixture is recorded. The positioning sensor is a type of distance sensor.

[0014] Preferably, in any of the above embodiments, the laser rangefinder and the proximity switch are both fixedly installed inside the rotating base, the detection end of the laser rangefinder is located upward at the top of the rotating base, the positioning sensor is fixedly installed at the top of the rotating base, and the positioning sensor is located on one side of the sample mold.

[0015] The above technical solution employs the following: a laser rangefinder sensor is installed inside the rotating base, with its detection end facing upwards at the top of the rotating base. It is used to measure the size of the sample, and its high-precision measurement capability ensures accurate sample size data. A proximity switch is also installed inside the rotating base, which accurately detects the rotational position of the rotating measuring base by sensing the metal plate on the measuring conveyor platform, and controls the start and stop of the rotating measuring base. A positioning sensor is fixed at the top of the rotating base, located on one side of the sample mold, and is used to detect the position of the sample, ensuring that the sample is in the correct position before measurement, thereby improving the accuracy and reliability of the measurement.

[0016] Preferably, in any of the above embodiments, the isolation and protection plate includes an electric telescopic rod connected to a central control unit and an isolation plate made of isolation material. The electric telescopic rod is fixedly installed inside the rotating base, and one end of the electric telescopic rod is fixedly installed with an isolation plate that moves inside the rotating base.

[0017] The above technical solution is adopted: the electric telescopic rod of the isolation protective plate is controlled by the central control unit and installed inside the rotating seat. When it is necessary to isolate the proximity switch, the electric telescopic rod extends or retracts, driving the isolation plate to move inside the rotating seat. The isolation plate is made of isolation material, which can effectively block external interference signals, ensure the accuracy of the proximity switch sensing signal, and thus ensure the accuracy of the position control of the rotating measuring seat.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. A rotary measuring seat for rotation adjustment is set in the middle of the measuring conveying table for transporting samples.

[0047] The working principle of this automated multi-sample measurement device is as follows:

[0048] When using this automated multi-sample measurement device, multiple samples are first placed on the measurement conveyor 1. The samples are located within the measurement mold base 32 of the sample mold 3. The central control unit is activated, controlling the rotary motor 21 of the rotating measuring base 2 to operate. The rotating base 22 rotates accordingly, driving the sample mold 3 and the measurement fixture 4 to move. The positioning sensor 8 monitors the sample position in real time to ensure that the sample is in the correct measurement position. When the sample reaches the measurement area, the measuring cylinder 41 of the measurement fixture 4 is activated. The measuring clamping head 42, with the cooperation of the pressure sensor 43, stably clamps the sample. At the same time, the laser rangefinder 5 starts working to measure the sample size and transmit the data. The data is transmitted to the central control unit. During the rotation of the rotating measuring seat 22, the proximity switch 6 monitors the position of the rotating seat 22 by sensing the sensing metal plate 9 on the circumference of the groove of the measuring conveyor table 1. When the designated position is reached, the central control unit controls the rotating motor 21 to stop rotating. If it is necessary to isolate the sensing signal of the proximity switch 6, the central control unit controls the electric telescopic rod 71 of the isolation protective plate 7 to move the isolation plate 72 for sensing isolation. After the measurement is completed, the measuring cylinder 41 releases the sample, the rotating measuring seat 22 continues to rotate, and the measured sample is rotated out. The new sample is rotated into the measurement area, and the measurement process is repeated to realize the automated and efficient measurement of multiple samples.

After the measurement is completed, the samples can be quickly assembled and disassembled, saving the sample measurement time and effectively improving the efficiency of sample measurement, which is convenient for large-scale sample measurement work.

[0051] 2. A proximity switch 6 is set on the circumference of the rotating measuring seat 2. The position of the rotating measuring seat 2 is controlled by the signal sensed by the proximity switch 6. This allows the rotating measuring seat 2 to drive the sample mold 3 and the measuring fixture 4 to make precise position adjustments, thereby improving the accuracy and convenience of sample measurement and disassembly.
