The outer side of the first slide rail 301 is slidably connected to the sliding seat 302 with freedom of movement, and the rear side of the sliding seat 302 is threadedly connected to the screw 307.

[0033] The beneficial effects of adopting the above technical solution are: through the base 4, the horizontal adjustment component 3 is utilized with the main plug-in mounting seat 5 and the plug-in block 6, and the first pulley 304 is driven by the motor 303 as a driver to rotate, and the second pulley 305 can be driven to rotate by the belt 306, thereby driving the screw 307 on the second pulley 305 to rotate.

[0038] In one embodiment of the present invention, a square groove is formed on the top of the base 4 , and the bottom of the second slide rail 13 is located in the square groove.

[0039] The beneficial effect of adopting the above technical solution is: a square groove is opened on the top of the base 4, and the bottom of the second slide rail 13 is located in the square groove, which facilitates the movement of the mobile seat 2 along the outer side of the second slide rail 13. At the same time, the setting of the base 4 does not affect the movement of the mobile seat 2.

[0040] In one embodiment of the present invention, two auxiliary seats 14 are provided on the front side of the movable seat 2 , and the side surfaces of the two auxiliary seats 14 are used to mount the through-beam photoelectric sensors 11 .

[0041] The beneficial effect of adopting the above technical solution is that the auxiliary seat 14 is provided on the movable seat 2, which facilitates the installation of the through-beam photoelectric sensor 11.

[0042] In one embodiment of the present invention, the vertical cross-section of the through-beam photoelectric sensor 11 is Z-shaped. When the bottom of the through-beam photoelectric sensor 11 is in contact with the top of the elastic column 10 , the pop-up end of the elastic column 10 is located below the sensing range of the elastic column 10 .

[0043] The beneficial effect of adopting the above technical solution is that when the bottom of the opposing photoelectric sensor 11 is in contact with the top of the elastic column 10, the pop-up end of the elastic column 10 is located below the sensing range of the elastic column 10, which facilitates limiting the position of the elastic column 10.

[0044] In one embodiment of the present invention, mounting plates are provided on the front side of the electric cylinder 1 , the front side of the second slide rail 13 and the side of the air cylinder 8 , and mounting holes for installation are provided on the mounting plates.

[0045] The beneficial effect of adopting the above technical solution is: by providing mounting plates and mounting holes on the electric cylinder 1, the second slide rail 13 and the cylinder 8, it is convenient to install the electric cylinder 1, the second slide rail 13 and the cylinder 8 on the designated shelf, which is convenient for installation.

[0046] Working principle: When using this device, install the electric cylinder 1, the second slide rail 13 and the air cylinder 8 to the specified position, drive the first pulley 304 to rotate by the motor 303, use the belt 306 to drive the second pulley 305 to rotate, use the screw 307 to drive the sliding seat 302 to move along the outside of the screw 307, and move the plug-in block 6 to the appropriate position. Then, drive the moving seat 2, the base 4, and the horizontal adjustment component 3 to move by the electric cylinder 1, and drive the main plug-in mounting seat 5 and the plug-in block 6 to move, so that the plug-in block 6 reaches the pre-plug-in position. At this time, the air cylinder 8 starts to work, and the cylinder 8 drives the connecting block 9, thereby pushing the elastic column 10 forward for insertion. The elastic column 10 is an elastic component, and usually it will be pushed forward along with the plug-in action of the mechanism until the plug-in is completed.

[0047] When a person's hand enters the working area of ​​the plug-in mechanism, the plug-in block 6 encounters an obstacle, that is, the person's hand, during the plug-in process and can no longer be inserted into the predetermined pre-plug-in position. At this time, the elastic column 10 will extend due to the resistance. Due to its elasticity, the elastic column 10 extends to the position sensed by the opposing photoelectric sensor 11. The opposing photoelectric sensor 11 will detect this obstruction and then send a signal to tell the electric cylinder 1 to stop working. In order to avoid pinching the person's hand, the cylinder 8 will automatically retract and stop the plug-in process to protect the safety of the personnel.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
