If the standby signal exists, the power supply is cut off in time after the operation is finished, and the safety performance of the equipment is guaranteed.
The upper pressing cylinder drives the upper pre-pressing module to move downwards for a first distance in the vertical direction and then move upwards for a first distance in the vertical direction, and the upper pressing cylinder works once.
The driving motor drives the sliding block supporting block to move a second distance in the first direction in the horizontal direction, and then the sliding block supporting block moves a second distance in the second direction opposite to the first direction in the horizontal direction, so that the driving motor works once.
The first direction is a direction away from the edge of the working platform.

A first gravity sensor, a second gravity sensor and a third gravity sensor are uniformly and fixedly arranged on the working platform; the gravity sensor is disposed on an upper surface of the work platform and is at least partially in direct contact with a portion of the gravity sensor when the device under test is placed on the work platform, the gravity sensor being capable of measuring a portion of the weight of the device under test it bears.
After receiving a starting signal, the microcontroller outputs power to the first gravity sensor, the second gravity sensor and the third gravity sensor respectively, the first gravity sensor, the second gravity sensor and the third gravity sensor enter a standby state, and the first pressure switch and the second pressure switch are supplied with power and enter the standby state; after the driving motor starts to work, respectively outputting detection instructions to the first gravity sensor, the second gravity sensor and the third gravity sensor, wherein the first gravity sensor, the second gravity sensor and the third gravity sensor start to detect the respective borne weights in real time, namely the first weight, the second weight and the third weight, respectively, 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 third direction to drive the sliding block supporting block to move a second distance to the first direction in the horizontal direction, then the driving motor sends preparation information to the upper pressure cylinder which starts to work, and the driving motor simultaneously controls the first pressure switch and the second pressure switch to enter a working state.
The first pressure switch and the second pressure switch respectively comprise a pressure sensor; and after the first pressure switch and the second pressure switch enter a working state, the pressure sensor detects the first pressure and the second pressure measured by the pressure sensor in real time and transmits the first pressure and the second pressure to the MCU.
Since the device under test is mechanically produced, whether the device under test is placed at an appropriate position can be detected by providing a plurality of gravity sensors. The unification of the measurement standards can only be guaranteed when in the proper position, otherwise the replacement of the device implementing the placing function should be prompted.
The left pressure switch and the right pressure switch respectively comprise a wireless power receiving coil, a rectifying and filtering circuit and a pressure sensor; the wireless power receiving coil converts a surrounding electromagnetic field into electric power, and the electric power supplies electric energy to the pressure sensor through the rectifying and filtering circuit; the pressure sensor detects the left pressure and the right pressure born by the pressure sensor in real time and transmits the left pressure and the right pressure to the MCU in real time.
The transmission of wireless power is only required after start-up, thereby reducing unnecessary loss of energy.
The upper air cylinder which starts to work detects whether the preparation information is received or not all the time, if not, the upper air cylinder does not perform any action, if yes, the upper air cylinder runs along a fourth direction to drive the upper pre-pressing module to move downwards at a first preset speed for a third distance, and the third distance is smaller than the first distance; after the upper pre-pressing module moves downwards for a third distance, the upper pressing cylinder operates in a fourth direction to drive the upper pre-pressing module to move downwards at a second preset speed, the second preset speed is smaller than the first preset speed until the first pressure, the second pressure, the left pressure and the right pressure received by the microcontroller are not zero, and the upper pressing cylinder stops operating and controls the upper pre-pressing module to be kept at the position.
The preparation information realizes the continuity and succession between the operations, so that each operation step can be orderly and efficiently carried out. And the design of the speed change at different stages simultaneously considers the detection efficiency and the efficiency.
The microcontroller judges whether the value of the first pressure at the moment meets a first pressure preset range or not, whether the value of the second pressure meets a second pressure preset range or not, whether the value of the left pressure meets a left pressure preset range or not, whether the value of the right pressure meets a right pressure preset range or not, if so, judges whether the value of the first pressure, the value of the second pressure, the value of the left pressure and the value of the right pressure meet a preset function F (p1, p2, p3 and p4) are 0 or not, and if so, judges that the detected device passes pressure detection.
The preset function is a function fitted through the sample pressure data, and p1, p2, p3 and p4 are variables of the preset function, namely a first pressure, a second pressure, a left pressure and a right pressure.

And after receiving the reply instruction, the upper pressing cylinder operates along a fifth direction opposite to the fourth direction to drive the upper pre-pressing module to move upwards for a first distance at a third preset speed, wherein the third preset speed is greater than the first preset speed. And after receiving the reply instruction, the driving motor operates along a sixth direction opposite to the third direction to drive the slider supporting block to move a second distance in a second direction opposite to the first direction in the horizontal direction.
And if the microcontroller judges that the numerical value of the pressure does not meet the corresponding pressure preset range, judging that the device to be tested needs impact measurement.
The invention sets impact re-detection for the device which does not pass the single pressure value, enables the fault which can be eliminated to be eliminated in time by applying external force, repairs the device in time during detection and improves the generation efficiency of the device.
When the microcontroller judges that the device to be tested needs impact measurement, the microcontroller sends an impact positioning reset instruction to the upper air cylinder. After the upper air cylinder receives the impact positioning and repositioning instruction, the upper air cylinder operates in a fourth direction to drive the upper pre-pressing module to move downwards at a fourth preset speed, and the fourth preset speed is lower than the second preset speed until any one of the first pressure, the second pressure, the left pressure and the right pressure received by the microcontroller reaches an upper pressure limit value; then the upper pressure cylinder operates along a fifth direction opposite to the fourth direction to drive the upper pre-pressing module to move upwards at a third preset speed, wherein the third preset speed is greater than the first preset speed; and then the upper air cylinder operates along a fourth direction to drive the upper pre-pressing module to move downwards at a second preset speed, the second preset speed is lower than the first preset speed until the first pressure, the second pressure, the left pressure and the right pressure received by the microcontroller are not zero, and the upper air cylinder stops operating and controls the upper pre-pressing module to keep at the position.
And the microcontroller judges whether the numerical values of all the pressures meet the corresponding pressure preset ranges and meet preset functions again, if so, the tested device is judged to pass the pressure detection, and if not, the tested device is judged not to meet the requirements.
If the microcontroller judges that all the pressure values meet the corresponding pressure preset range but do not meet the preset function, the device to be tested needs to be measured for the second time.
The invention sets the process of secondary detection for the element which does not pass the primary detection, thereby greatly avoiding the probability of missed judgment.
And when the microcontroller judges that the tested device needs secondary measurement, a positioning and restarting instruction is sent to the upper pressure cylinder, and a backspacing instruction is sent to the driving motor. After receiving the positioning and repositioning instruction, the upper air cylinder operates in a fifth direction opposite to the fourth direction to drive the upper pre-pressing module to move upwards at a third preset speed by a difference value between a first distance and a third distance, wherein the third preset speed is greater than the first preset speed; and then the upper air cylinder operates along a fourth direction to drive the upper pre-pressing module to move downwards at a second preset speed, the second preset speed is lower than the first preset speed until the first pressure, the second pressure, the left pressure and the right pressure received by the microcontroller are not zero, and the upper air cylinder stops operating and controls the upper pre-pressing module to keep at the position. After receiving the backspacing instruction, the driving motor operates along a sixth direction opposite to the third direction to further drive the slider supporting block to move a fourth distance in a second direction opposite to the first direction in the horizontal direction, and the fourth distance is far smaller than the second distance.
And the microcontroller judges whether the numerical values of all the pressures meet the corresponding pressure preset ranges and meet preset functions again, if so, the tested device is judged to pass the pressure detection, and if not, the tested device is judged not to meet the requirements.
