The working principle and the beneficial effects of the technical scheme are as follows: the positioning module 20 is adopted at the positioning station to perform primary positioning adjustment on the shell 70, so that after the shell 70 moves to the column 520, the positioning hole 710 of the shell 70 can be corresponding to the positioning round hole 522 and the positioning pin 940, therefore, after the negative pressure hole 521 on the column 520 forms negative pressure, the shell 70 sleeved on the column 520 can be sucked, the vertical direction of the shell 70 is limited, then the positioning pin 940 can be inserted into the positioning hole 710 and the positioning round hole 522, and the horizontal direction of the shell 70 can be limited through the positioning pin 940, so that the shell 70 is clamped and fixed;
however, when the material taking mechanism 30 drives the positioning module 20 to sleeve the casing 70 on the column 520, the casing 70 may have a position offset phenomenon, if the CCD camera unit 250 of the positioning module 20 is adopted to perform positioning detection on the casing 70 at the position again each time, the positioning accuracy will be improved, but the processing time will be increased undoubtedly, and the processing efficiency will be affected; therefore, the process of horizontal limiting the housing 70 by the positioning pin 940 is adopted to detect whether the housing 70 is deviated, so that the efficiency can be improved, the CCD camera unit 250 is not required to be used for positioning every time, and positioning adjustment is only required when the housing 70 is deviated;
specifically, after the housing 70 is placed on the column 520, the three-axis driving assembly controls the fixing portion 910 to drive the whole processing positioning mechanism 90 to move to a designated position above the fixture 5 (a position corresponding to the positioning pin 940 and the positioning round hole 522), and then move downward; if the positioning hole 710 and the positioning round hole 522 are not deviated, the positioning pin 940 can be smoothly inserted into the positioning hole 710 and the positioning round hole 522, the positioning pin 940 and the positioning hole 710 limit the horizontal direction of the shell 70, then negative pressure is formed in the negative pressure hole 521, the principle of vacuumizing the vacuum hole of the positioning column 121 is the same, the adsorption force is formed on the inner top surface of the shell 70, thereby limiting the vertical direction of the shell 70, realizing the clamping and fixing of the shell 70, and then the shell 70 can be processed; if the positioning hole 710 and the positioning round hole 522 are offset, the positioning pin 940 will contact with the top surface of the housing 70, and in order to prevent the positioning pin 940 from damaging the surface of the housing 70, the positioning pin 940 is connected to the fixing sleeve 920 through the spring 950, so that after the positioning pin 940 contacts and bears force with the housing 70, the spring 950 will be compressed and the top end of the connecting rod 930 slides in the fixing sleeve 920 as the fixing portion 910 moves down; if this occurs, the machining positioning mechanism 90 may be removed first, and then the positioning module 20 is utilized to perform positioning adjustment on the housing 70;
through the design, whether the shell 70 exists on the column 520 or not can be detected through the negative pressure hole 521 (the principle is the same as that of a vacuum hole, and details are not repeated), the adsorption force can be generated on the shell 70, the horizontal direction of the shell 70 can be limited through the arranged processing positioning mechanism 90, and the clamping and fixing of the shell 70 can be realized through cooperation with the negative pressure hole 521; meanwhile, the machining position of the shell 70 can be repositioned through the machining positioning mechanism 90 so as to judge whether the position of the shell 70 meets the machining requirement, so that the accuracy of the machining position of the explosion-proof valve 720 on the shell 70 is ensured, the secondary positioning detection is not required to be carried out on the clamp 50 each time through the positioning module 20, and the efficiency is improved.
In addition, as shown in fig. 10, the processing positioning mechanism 90 should avoid the laser processing area of the housing 70; if the number of the processing and positioning mechanisms 90 is four as shown in fig. 10, it is preferable that the fixing portions 910 of the four processing and positioning mechanisms 90 are connected by an i-shaped connecting piece, and the front and rear two cross bars of the i-shape are parallel to the connecting line of the positioning round hole 522 and the negative pressure hole 521, so as to let out the notch position of the explosion-proof valve 720, and the middle longitudinal bar of the i-shape is used for being connected with the triaxial driving assembly so as to drive the four processing and positioning mechanisms 90 to move simultaneously.
As shown in fig. 9, in one embodiment, a pressure sensor 960 is disposed between the bottom surface of the fixing sleeve 920 and the spring 950, for detecting whether the positions of the positioning hole 710 and the positioning round hole 522 are deviated;
if the pressure value detected by the pressure sensor 960 gradually increases along with the downward movement of the processing positioning mechanism 90, which indicates that the positions of the positioning hole 710 and the positioning round hole 522 are deviated, the material taking mechanism 30 moves the positioning module 20 to the upper side of the corresponding housing 70, so as to perform positioning adjustment on the housing 70;
if the pressure value detected by the pressure sensor 960 does not change with the downward movement of the machining positioning mechanism 90, it indicates that the positions of the positioning hole 710 and the positioning round hole 522 are not shifted.
The working principle and the beneficial effects of the technical scheme are as follows: a monitoring unit in communication with the pressure sensor 960 for monitoring changes in the pressure sensor 960 in real time; whether the housing 70 is offset is detected by the pressure sensor 960 arranged between the bottom surface of the fixed sleeve 920 and the spring 950, if the housing 70 is offset, the positioning pin 940 is in contact with the top surface of the housing 70, then the spring 950 is gradually compressed and the elastic acting force is increased along with the downward movement of the processing positioning mechanism 90, then the force acting on the pressure sensor 960 is gradually increased, the pressure value detected by the pressure sensor 960 is gradually increased, after the pressure value detected by the pressure sensor 960 is gradually increased, the processing positioning mechanism 90 can be controlled to return to the initial position, the positioning module 20 is moved to the upper side of the corresponding housing 70 through the material taking mechanism 30, and the housing 70 is subjected to positioning adjustment, so that the position offset condition of the housing 70 can be detected in the process of clamping and fixing the housing 70, and the positioning module 20 is started for secondary positioning adjustment only when the offset occurs, so that the processing procedure is saved, the processing efficiency is improved, and the detection accuracy is better.
