[0029] Further as Figure 4 As shown, a mounting groove 500 is provided in the middle of the top surface of the operating table 100 , and a push plate 501 is movably engaged inside the mounting groove 500 .

[0030] By setting the installation groove 500, the push plate 501 can be inside the installation groove 500 when not moving. By setting the push plate 501, the mobile phone screen can be pushed out from the fixed frame 101 after being fixed in the middle frame.

[0031] The present solution has the following working process: when assembling the screen and the middle frame, the middle frame is first engaged in the fixing frame 101 so that the position of the middle frame is fixed. At this time, the bottom surface of the middle frame contacts the top surface of the pushing plate 501. At this time, the PLC controller 800 is operated. The PLC controller 800 controls the second cylinder 700 to start and push the distance sensor 701 to move so that the distance sensor 701 moves to the upper side of the edge of the middle frame. The distance sensor 701 detects the distance between the top surface of the middle frame and the distance sensor 701, and transmits the data to the PLC controller 800. The PLC controller 800 compares the acquired data with the distance sensor 701. The PLC controller 800 calculates the fixed value between the top surface of the operating table 100 and the height of the middle frame, and then controls the second cylinder 700 to return to its original position. The PLC controller 800 obtains the downward movement distance of the third cylinder 704 corresponding to the different middle frame heights stored in the PLC controller 800 according to the obtained middle frame height data. Then, the screen is placed horizontally in the installation frame 102 so that the top surface of the screen contacts the bottom surface of the air cushion 200. By controlling the PLC controller 800, the suction pump 302 is started, and the suction cup 300 sucks the top surface of the screen, so that the position of the screen is fixed. At this time, the bottom surface of the screen and the bottom surface of the installation frame 102 are in contact. The surfaces are on the same horizontal plane, the PLC controller 800 is operated, and the PLC controller 800 controls the output ends of the two third cylinders 704 to move downward synchronously until the installation frame 102 is stuck in the fixed frame 101. At this time, the bottom surface of the installation frame 102 and the top surface of the fixed frame 101 are on the same horizontal plane. At this time, the bottom surface of the screen and the top surface of the fixed frame 101 are on the same horizontal plane, and the PLC controller 800 is operated. The suction pump 302 is turned off, and the position of the screen is unfixed. At the same time, the PLC controller 800 controls the first cylinder 402 to start, so that the movable frame 400 moves, and the movement of the movable frame 400 drives the fixed plate 201 to move, and the fixed frame 201 is fixed. The movement of plate 201 drives the movement of air cushion 200, and the movement of air cushion 200 pushes the screen to engage on the top surface of the middle frame, so that the screen is assembled. Then, the output end of the first cylinder 402 is controlled to move upward, so that the installation frame 102 returns to its original position. The toothed rod 504 is manually rotated, and the toothed rod 504 rotates to drive the rack 503 to move upward. At this time, the spring 601 is stretched, and the rack 503 moves upward to drive the push plate 501 to move upward, so that the middle frame is pushed out of the fixed frame 101. After the middle frame is taken out, the restriction on the toothed rod 504 is released, and the spring 601 releases the elastic force to pull the rack 503 to reset, and finally the push plate 501 is engaged in the installation groove 500.

[0032] According to the above working process, it can be known that: the screen located in the installation frame 102 can be fixed by the set suction cup 300, and the set air cushion 200 can protect the top surface of the screen when the screen is pressed and assembled with the top surface of the middle frame, thereby avoiding the screen from being broken and damaged due to pressing, and the set second cylinder 700 and distance sensor 701 can adjust the downward movement distance of the third cylinder 704 according to the height of the different middle frames, thereby further protecting the screen, so that the surface of the screen is not easily damaged when pressed, thereby reducing the damage rate of the screen during assembly.

[0033] By providing the push plate 501, the rack 503, the toothed rod 504 and the spring 601, the screen can be conveniently taken out from the fixed frame 101 after being assembled with the middle frame, thereby improving the convenience of taking out the middle frame.

The PLC controller 800 compares the acquired data with the distance sensor 701 and the operating table 100. The PLC controller 800 calculates the fixed value between the top surfaces to obtain the height of the middle frame, and then the PLC controller 800 controls the second cylinder 700 to return to its original position. The PLC controller 800 obtains the downward movement distance of the third cylinder 704 corresponding to the different middle frame heights stored in the PLC controller 800 according to the obtained middle frame height data.
