The temperature of the equipment can be continuously raised due to friction generated by continuous lifting, and the quality of nut embedding and even the damage of the equipment can be influenced due to overhigh temperature, so that the equipment stops working based on the temperature innovatively, and the set upper and lower temperature limits can ensure that the temperature is effectively reduced.

A first gravity sensor, a second gravity sensor, a third gravity sensor, a fourth gravity sensor and a fifth gravity sensor are uniformly and fixedly arranged on the nut placing and positioning mechanism; the sensor is arranged on the upper surface of the nut placing and positioning mechanism, and when plastic is placed on the nut placing and positioning mechanism, the plastic is directly contacted with the gravity sensor, and the gravity sensor can measure partial weight of the plastic born by the gravity sensor.

After receiving a starting signal, the microcontroller outputs power to the first gravity sensor, the second gravity sensor, the third gravity sensor, the fourth gravity sensor and the fifth gravity sensor respectively, and the first gravity sensor, the second gravity sensor, the third gravity sensor, the fourth gravity sensor and the fifth gravity sensor enter a standby state; after the driving motor starts to work, respectively outputting detection instructions to the first gravity sensor, the second gravity sensor, the third gravity sensor, the fourth gravity sensor and the fifth gravity sensor, wherein the first gravity sensor, the second gravity sensor, the third gravity sensor, the fourth gravity sensor and the fifth gravity sensor start to detect the respective borne weights, namely the first weight, the second weight, the third weight, the fourth weight and the fifth weight, in real time, and transmit the weights to the driving motor in real time; the drive motor compares each weight with a respective corresponding weight threshold and controls a timer present therein based on the comparison; when at least one weight does not meet the corresponding weight threshold value, the timer does not start timing and is cleared, and only when all weights meet the corresponding weight threshold values, the timer starts timing; when the timing result of the timer is longer than the preset time, the driving motor operates along the first direction to drive the guide flat plate to move downwards at the first preset speed by a second distance threshold, and then the driving motor sends preparation information to the hot pressing cylinder which starts to work.

Since the plastic product is mechanically produced, whether the plastic product is placed at a proper position can be detected by providing a plurality of gravity sensors. Only when the nut is placed at a proper position, the nut can be placed to realize hot pressing, otherwise, the device for realizing the placing function should be reminded to be placed again.

The wireless sensor is characterized in that a first wireless sensing unit is arranged at one position of the nut column, a second wireless sensing unit is arranged at the second position of the nut column, a third wireless sensing unit is arranged at the third position of the nut column, fourth wireless sensing units are arranged at the fourth position of the nut column, a fifth wireless sensing unit is arranged at the fifth position of the nut column, a sixth wireless sensing unit is arranged at the sixth position of the nut column, and a seventh wireless sensing unit is arranged at the seventh position of the nut column.

The wireless sensing unit comprises a wireless power receiving coil, a rectifying and filtering circuit and a sensor assembly which are electrically connected in sequence; the wireless power receiving coil converts an ambient electromagnetic field into electric power, and the electric power supplies electric energy to the sensor assembly through the rectifying and filtering circuit; the sensor assembly comprises a distance sensor and a pressure sensor which are electrically connected in parallel, the distance sensor detects the distance between the distance sensor and an opposite obstacle, the pressure sensor detects the pressure borne by the pressure sensor, and the distance sensor and the pressure sensor transmit the detected distance and pressure to a hot-pressing air cylinder which starts to work in real time.

The transmission of wireless power is only required after start-up, thereby reducing unnecessary loss of energy.

The hot pressing cylinder which starts to work detects whether the preparation information is received or not all the time, if not, the hot pressing cylinder does not perform any action, if yes, whether all the distances meet a preset distance range or not is further detected, if not, the hot pressing cylinder does not perform any action, if yes, the hot pressing cylinder runs along a first direction to drive the nut column pressing plate to move downwards at a second preset speed by a third distance threshold value, and the third distance threshold value is smaller than the first distance threshold value; after the nut column pressing plate moves downwards by a third distance threshold value, the hot pressing cylinder runs along the first direction to drive the nut column pressing plate to move downwards at a third preset speed, the third preset speed is lower than the second preset speed until all the pressures meet a preset pressure range, and the hot pressing cylinder stops running and controls the nut column pressing plate to keep the position for a preset time; after the preset time, the hot pressing cylinder sends a completion message to the driving motor, and simultaneously runs along a second direction opposite to the first direction, so that the nut column pressing plate is driven to move upwards at a fourth preset speed by a first distance threshold, wherein the fourth preset speed is greater than the second preset speed.

The preparation information realizes the continuity and succession between the operations, so that each operation step can be orderly and efficiently carried out. The distance sensor is used for detecting whether the nut is placed perfectly or not, and hot pressing can be achieved only when the nut is placed perfectly. The pressure sensor can ensure the moderate heat pressure degree, so that the nut can be embedded deeply but not excessively, and the hot pressing effect is ensured. And the hot pressing effect is very good due to the speed change of different stages and the design of preset time, and the hot pressing efficiency is improved.

The driving motor detects whether the preparation information can be received or not after sending the preparation information to the hot pressing cylinder, if not, the driving motor does not perform any action, and if so, the driving motor operates along a second direction opposite to the first direction to drive the guide panel to move upwards at a fourth preset speed by a second distance threshold, wherein the fourth preset speed is greater than the first preset speed.

The completion information realizes the continuity and the continuation between the operations, and the nearly simultaneous operation of the driving motor and the hot-pressing cylinder greatly improves the working efficiency of the equipment.
