The plastic shell is usually formed by injection molding or melt plasticizing and demolding. The edge of the plastic shell formed by melt plasticizing and demolding usually has a large number of burrs. Workers manually deburr the plastic shell, which is low in efficiency and unstable in quality. SUMMARY

[0003] In order to improve the problems of low efficiency and unstable quality of manual deburring, the application provides a device and method for deburring a circuit breaker plastic shell and a storage medium thereof.

If the transmission stroke data is equal to the placement stroke threshold value, the shell placement data is 0. If the position pressure data is less than the correct pressure threshold value at this time, it means that the circuit breaker shell is aligned and placed in the correct position, such as being aligned with the adjustment base 311 or the clamping base 21. If the position pressure data is greater than the correct pressure threshold value, it means that the circuit breaker shell is not placed in the correct position, i.e. not aligned, which may be due to sensor failure or sensor aging causing the transmission data to be too slow. When the transmission stroke data is equal to the placement stroke threshold value, the output stop displacement instruction speed is slow, which causes the driving member to stop moving late, resulting in that the transmission stroke data is not equal to the placement stroke threshold value. At this time, the adjustment threshold value is adjusted, and the adjustment threshold value is a preset adjustment amplitude, such as reducing the corresponding placement stroke threshold value by a certain value, for example, the placement stroke threshold value-1. Test again until the position pressure data is less than the correct pressure threshold value, and replace the placement stroke threshold value at this time with the original placement stroke threshold value.

[0079] Referring to Figure 6 and Figure 7 , the method further comprises the following steps:

[0080] S2, obtain time data, the sensing signal includes deburring stroke data and deburring pressure data, and the correction signal includes close-to-back adjustment data and deburring track adjustment data;

[0081] S21, determine the deburring state by deburring stroke data and preset deburring stroke threshold value;

[0082] S22, determine the deburring depth data by deburring pressure data and preset deburring pressure threshold value;

[0083] S23, determine the close displacement segment and the deburring displacement segment by deburring stroke data;

[0084] S24, determine the close backoff adjustment data by close displacement segment, time data, preset deburring depth threshold value and preset deburring fluctuation time threshold value;

[0085] S25, determine the deburring trajectory adjustment data by deburring displacement segment, time data, deburring depth threshold value and deburring fluctuation time threshold value;

[0086] S26, determine the new deburring stroke threshold value by close backoff adjustment data, deburring trajectory adjustment data, preset material threshold value and original deburring stroke threshold value, and replace the original deburring stroke threshold value;

[0087] S27, acquire the sensing signal again, and calculate the close backoff adjustment data and the burr trajectory adjustment data until the close backoff adjustment data and the burr trajectory adjustment data are zero.

[0088] In detail, the deburring stroke data is the movement stroke of each driving member included in the fine deburring mechanism 3, the deburring stroke threshold is the theoretical movement trajectory, that is, when the deburring stroke data is equal to the deburring stroke threshold, the deburring drill bit 342 will move on the corresponding movement trajectory, thereby deburring the plastic shell of the circuit breaker; the deburring pressure data is the pressure detected by the deburring drill bit 342, which is usually larger when the deburring is in contact with the burr, and the pressure is zero when it is idle. Under normal circumstances, the deburring drill bit 342 is in contact with the edge of the circuit breaker plastic shell, or suspended outside the circuit breaker plastic shell for deburring, and the deburring pressure data will be less than the deburring pressure threshold. Once it is directly in contact with the edge of the circuit breaker plastic shell and the sensor is aged or fails, the deburring stroke data detected is less than the deburring stroke threshold, causing each driving member of the fine deburring mechanism 3 to continue to move in the wrong direction, causing the deburring drill bit 342 to abut against the circuit breaker plastic shell or even drill into the circuit breaker plastic shell, which will cause the deburring pressure data to be much greater than the deburring pressure threshold. Therefore, the distance between the deburring drill bit 342 and the circuit breaker plastic shell can be obtained by comparing the deburring pressure data with the deburring pressure threshold. According to the deburring stroke data, it can be determined in which movement section the current fine deburring mechanism 3 is in, for example, to determine which stage is to control the deburring drill bit 342 to approach the circuit breaker plastic shell and which stage is to control the deburring drill bit 342 to deburr on the circuit breaker plastic shell, thereby dividing it into two stages, namely the approaching displacement section and the deburring displacement section. In the approaching displacement section, the deburring drill bit 342 is theoretically not in contact with the circuit breaker plastic shell, so the deburring depth is zero and the deburring pressure data is zero. If the deburring pressure data is generated, it indicates that it is in contact with the burr or the circuit breaker plastic shell. Whether it is in contact with the burr or the circuit breaker plastic shell is determined by the time data. For example, when the deburring drill bit 342 is in contact with the burr, the burr will be removed, and the deburring pressure data will rise and then return to zero. The time data of the rising and returning to zero is recorded and compared with the deburring fluctuation time threshold. If it is within the interval range of the deburring fluctuation time threshold, it is determined to be in contact with the burr. If it is outside the interval range of the deburring fluctuation time threshold, it indicates that the deburring drill bit 342 has been in contact with the circuit breaker plastic shell for too long. At this time, the corresponding approaching retreat adjustment data is output to control the deburring drill bit 342 to move outward and reduce the direct contact with the circuit breaker plastic shell, which may cause damage to the circuit breaker plastic shell. In the deburring displacement section, the deburring process needs to be performed, but the deburring still records the time data of the deburring pressure data fluctuation, thereby determining whether it is in direct contact with the circuit breaker plastic shell or even drilled into it, and outputting the corresponding deburring trajectory adjustment data.The material threshold is the material adopted by the plastic shell of the circuit breaker, so that the excessively large deburring pressure data generated is calculated to be how deep the circuit breaker plastic shell is penetrated, and then the deburring stroke threshold is corrected to automatically realize the accuracy of next processing.
