Wherein, the utility model discloses a database is peach lin information Management Platform (hereinafter for short TIMP-TaolinInformation Management Platform), as shown in FIG. 3, the monitor is fixed to be set up in carousel formula ultrasonic welding machine, and be connected with ultrasonic welding machine, the "voltage of butt fusion process is gathered to the monitor, the electric current, atmospheric pressure, frequency, output, the butt fusion time, the amplitude, humidity" data, the monitor passes through net twine transmission data with the switch, data that will collect are transmitted to cloud ware and are carried out the data presentation at the TIMP system through the ethernet chip through the switch, cloud ware adopts ethernet and workshop computer network to link to each other, so that personnel log in the computer TIMP system and carry out the equipment monitoring. On one hand, the TIMP system at the webpage end can set upper and lower limits of alarm parameters, the alarm parameters are synchronized to the monitor, whether the alarm is given or not can be judged by the monitor, if the parameters are within the set range, no alarm signal can be generated, the product is good, the manipulator clamps the product, and the product is placed in a good box; if the parameters exceed the range, a sound and character alarm signal is sent out to indicate that the product is a defective product, and the manipulator clamps the product and places the product into a defective product box. In the aspect of alarming, the turntable type ultrasonic welding machine body gives an alarm by sound and gives a corresponding character alarm prompt, the TIMP system also sends character alarm information, and on the other hand, a large amount of production data of voltage, current, air pressure, frequency, yield, fusion time, amplitude and humidity are stored, the production is optimized by utilizing a big data technology, if decision suggestions such as production equipment improvement suggestions are provided, for example, if voltage instability is found, an improvement suggestion of installing a power supply voltage stabilizer can be provided. Therefore, the monitoring of the product quality and the optimized production in the production process of the ultrasonic welding machine are realized.

Wherein, the utility model relates to a technological parameter include electric current, voltage, frequency and fusion joining time, atmospheric pressure, the amplitude, humidity (the electric current, the voltage indicates the actual electric current of current time man-hour, voltage, the frequency indicates the actual resonant frequency of current time man-hour, send resonant frequency's time when the fusion joining time indicates the product of processing, atmospheric pressure indicates the pressure of processing the product, the amplitude indicates the amplitude of ultrasonic transducer and amplitude transformer equipment, humidity indicates the humidity of current environment) can influence the effect of product processing, plastics product defective products mainly because the fusion joining is not enough and the fusion joining excessively causes, when the electric current, voltage, frequency, the fusion joining time, the atmospheric pressure undersize can cause the fusion joining not enough, if the electric current, voltage, frequency, the fusion joining time, the too big fusion joining that can cause of fusion joining, the fusion joining time is the factor that has decisive influence to the fusion joining effect, only set for "fusion joining time, however, since the "welding time" is not monitored and it is unknown whether the actual "welding time" reaches the set welding time, it is necessary to monitor the "welding time". The appropriate welding time for each application is determined by experimentation. Increasing the weld time increases the weld strength until an optimal time is reached. Further increases in weld time can result in reduced or only slightly increased weld strength, while at the same time increasing weld flash and increasing the likelihood of part marking. Avoiding over-welding is important because excessive flash to be trimmed can occur, which can degrade the quality of the weld and create leaks in the parts to be sealed. The bonding tool may scratch the surface. Melting and fracture may also occur at parts of the part remote from the joint area at longer welding times, especially at holes, weld lines and sharp corners in the molded part.

Amplitude is an important parameter for controlling the extrusion flow rate of thermoplastics. In the ultrasonic welding process, if the amplitude is too small, the welding energy is insufficient, and the welding spot is not firmly welded. If the amplitude is too large, over-welding, flux or weld-through may result. At high amplitudes, the heating speed of the welding interface is high, the temperature rises, the flow speed of the molten material is high, the molecular orientation is increased, a large amount of flash is generated, and the strength of the welding seam is low. High amplitude is necessary to initiate melting. Too low an amplitude results in uneven onset of melting and premature solidification of the melt. When increasing the amplitude, a greater amount of vibration energy is dissipated in the thermoplastic and the parts to be welded are subjected to greater stress. The highest amplitude is generally used that does not cause excessive damage to the part to be welded when the amplitude is constant throughout the welding cycle. For crystalline plastics such as polyethylene and polypropylene, the effect of amplitude is much greater than for non-crystalline plastics such as ABS and polystyrene. This may be due to the more energy required for melting and welding of the crystalline plastic.

The moisture content in the material affects the weld strength. Hygroscopic materials such as polyester, polycarbonate and especially nylon absorb moisture from the air. The water absorbed during welding boils at 100 ℃, and the residual gas can generate air holes and possibly degrade the plastic at the joint surface, resulting in poor appearance, poor joint and difficulty in obtaining hermetic sealing. For best results, these materials should be welded immediately after molding. Special ovens may be used to dry the parts prior to welding, but care must be taken to avoid material degradation.

Therefore, the utility model discloses a voltage transformer and current sensor collect voltage, current information, and ultrasonic welding machine's working power supply is 220V power frequency alternating current. The voltage transformer and the current transformer are used for realizing the real-time monitoring and acquisition of the single-phase alternating current power supply. The detection principle of the voltage and the current of the alternating current power supply is that the high voltage and the high current of the alternating current power supply are converted into the low voltage which can be detected and processed by the ARM chip through a voltage transformer and a current transformer. The alternating voltage detection range is AC0V-AC 400V.

As shown in fig. 5, which is a schematic diagram of a working circuit of a voltage transformer, as shown in fig. 5, an alternating voltage signal of a power supply is input to a primary winding of a current type voltage transformer through a series current limiting resistor, is output through a secondary side of the transformer, and an output matching resistor converts the output current signal into a voltage signal, which is sent to an ARM chip for sampling processing. The series circuit selects 1 150K omega resistor, and when the input voltage is 0-400 v, the linear transformation range is met.

As shown in FIG. 6, the working circuit schematic diagram of the current sensor is shown, as shown in FIG. 6, the alternating current detection range is AC0A-AC10A, the current signal of the alternating current power supply is directly connected to the primary side winding of the current sensor, the induced current is output through the secondary side of the sensor, the output matching resistor converts the current signal into a voltage signal, and the voltage signal is sent to the ARM chip for sampling processing.

The utility model discloses a humidity transducer collects humidity data, as shown in FIG. 14, and the voltage range of humidity transducer output is 0.5 ~ 4.5v, carries out analog-to-digital conversion with the voltage of output, reachs the humidity value.

The utility model discloses an amplitude data is collected to vibration sensor, as shown in FIG. 13, and the voltage range of vibration sensor output is 0.5 ~ 4.5v, carries out analog-to-digital conversion with the voltage of output, reachs the amplitude value.

The utility model discloses a frequency and weld time monitoring circuit collect frequency and weld time data, like the circuit schematic diagram shown in figure 8, the frequency of ultrasonic wave utilizes the inside input of ARM chip to catch the function with ultrasonic processor weld time, and the timer realizes with the counter. The frequency of the ultrasonic wave can be obtained by calculating a correlation formula, and the welding time of the ultrasonic wave machine is obtained by calculating the starting point and the end point of the ultrasonic wave.

As shown in fig. 9, the product quality is determined, and the threshold of the alarm parameter set by the person at the computer terminal is sent to the cloud server and stored in the database, and at this time, the cloud server obtains the upper and lower limits (threshold) of the set data. After the monitor is started, whether the ultrasonic wave is sent or not is judged, and if the ultrasonic wave is not sent, the monitor does not acquire data. If ultrasonic waves are sent out, the monitor collects and completes data, the data are sent to the cloud server, the cloud server judges according to the threshold value, if one or more parameters exceed the range, the data are judged to be defective products and alarm, and if not, the data are judged to be the defective products and the alarm is not given. The server saves the data in a database, returns a threshold value to the monitor, synchronizes upper and lower limits of parameters of voltage, current, air pressure, frequency, yield, fusion time, amplitude and humidity to the monitor, and judges whether the parameters during processing are in a normal range, if one or more parameters exceed the range, the monitor judges that the parameters are defective products and gives an alarm, otherwise, the monitor judges that the parameters are non-defective products and does not give an alarm.

The specific alarm is realized as shown in fig. 10, parameters set by a person at a webpage end are stored in a server, and parameters of 'voltage, current, air pressure, frequency, yield, welding time, amplitude and humidity' are monitored synchronously at upper and lower limits, the monitor can judge whether the parameters are in a normal range during processing, if the monitored parameters are in a set range, the main body of the rotary disc type ultrasonic welding machine is informed of no alarm through serial port communication, and a manipulator is controlled to move good products into a good product box. If one or more parameters exceed the range, the main body of the rotary disc type ultrasonic welding machine is informed of sound alarm and corresponding character alarm prompt (prompting a certain parameter fault) through serial port communication, and the discharging manipulator is controlled to move the defective products into a defective product box. Meanwhile, the monitor sends an alarm signal to the server, and when the TIMP system at the web page end receives an alarm message, for example, when the air pressure is low, the air pressure of the machine number 3 in the workshop of "C1 is 100kpa, and the air pressure is lower than the set lower limit" is reported.

And then 160, 170, 180 and 190kpa are used for testing, wherein 160, 170 and 180kpa are defective products, 190kpa is a good product, and the lower limit value is set to 190 kpa. The upper limit value is similar to this, assuming that the upper limit value is determined to be 720 kpa.

The upper limit value is similar to this, assuming that the upper limit value is determined to be 0.2 s. Thus, the air pressure threshold value can be set by the TIMP system on the web page side to be less than 0.02s and greater than 0.2 s.
