[0032] like Figure 1 As shown, the positioning and lifting assembly 1 includes a positioning frame 11, a lifting motor 12 is provided at the bottom of the positioning frame 11, the top output end of the lifting motor 12 is connected to a lifting platform 13, a positioning pin 13a is provided on the top of the lifting platform 13 for positioning and locking the shell and the feed carrier, and the lifting platform 13 is slidably connected to the positioning frame 11 through a vertically arranged linear slide rail 13c; a blocking mechanism 14 is provided on the side of the positioning frame 11, and a positioning detection mechanism 15 is provided on the blocking mechanism 14 for positioning and locking the shell and the feed carrier.

[0033] like Figure 1 and Figure 2 As shown, the positioning frame 11 is provided with a lifting limit slot-type photoelectric 11a, and the lifting platform 13 is provided with a lifting limit sensor piece 13b corresponding to the lifting limit slot-type photoelectric 11a. The lifting limit slot-type photoelectric 11a cooperates with the lifting limit sensor piece 13b to limit the lifting stroke of the lifting platform 13 to avoid interference with other components.

[0034] like Figure 1 As shown, the X-axis moving module 2 includes an X-axis moving block 21, an X-axis encoder 22 and an X-axis moving mounting frame 23, wherein: the X-axis moving mounting frame 23 is arranged on one side of the positioning and lifting assembly 1, and the X-axis moving block 21 is slidably connected to the X-axis moving mounting frame 23 along the X-axis direction through a motor and a screw drive; the X-axis encoder 22 is arranged at one end of the X-axis moving mounting frame 23 for detecting the position of the X-axis moving block 21.

The horizontal moving stroke of the X-axis moving block 21 is limited by the cooperation of the X-axis limit sensor piece 21a and the X-axis limit slot-type photoelectric 23a to avoid interference with other components.

[0036] like Figure 1 As shown, the Y-axis moving module 3 includes a Y-axis moving block 31, a Y-axis encoder 32, a Y-axis moving mounting frame 33 and a support rail mechanism 34, wherein the front end of the Y-axis moving mounting frame 33 is connected to the X-axis moving block 21; the Y-axis moving block 31 is slidably connected to the Y-axis moving mounting frame 33 along the Y-axis direction through a motor and a screw drive; the Y-axis encoder 32 is arranged at one end of the Y-axis moving mounting frame 33 for detecting the position of the Y-axis moving block 31; the support rail mechanism 34 is arranged at the rear end of the Y-axis moving mounting frame 33, and its upper end is slidably connected to the rear end of the Y-axis moving mounting frame 33 along the X-axis direction.

During this process, the positioning pin 13a cooperates with the positioning groove on the feed carrier to ensure that the shell and the feed carrier are accurately positioned with the upper end surface of the lifting platform 13. When the shell and the feed carrier are lifted to the detection position, the lifting platform 13 stops moving, and the distance measuring mechanism 4 performs positioning movement through the X-axis moving module 2 and the Y-axis moving module 3 to detect the specified position of the shell. According to the detection results and the data feedback of the X-axis encoder 22 and the Y-axis encoder 32, the program determines whether the assembly of the shell is qualified.

[0039] In summary, the utility model discloses an automatic detection device for shell assembly, which realizes automatic loading and unloading detection of shells. The detection device can quickly detect shells of different shapes and sizes with fast detection speed and high accuracy.
