The flipping arm 211 is rotated by 90 degrees by the flipping motor 221, thereby driving the circuit board 530 to flip to a plane substantially parallel to the plane defined by the second coordinate direction Y and the third coordinate direction Z. The middle frame 600 is picked up by the middle frame moving device 300 and moves the middle frame 600 above the screen 510, i.e., above the first position, as shown in fig. 5.

And step 3: whether the strip hole 610 and the tilted end of the circuit board 530 are aligned or not is detected by the detection device 400.

The following describes a detection process of the detection apparatus 400 by taking the detection apparatus 400 including an image capturing device and an edge detection module as an example. The image acquisition device acquires the image below the circuit board, and sends the acquired image to the edge detection module, and the edge detection module judges whether the tilting end of the circuit board 530 is located in the elongated hole 610. If the tilting end of the circuit board 530 is not identified from the image, the middle frame motion device 300 is controlled to drive the middle frame 600 to move along the first coordinate direction X, so that the tilting end of the circuit board 530 moves to the middle of the elongated hole 610 in the first coordinate direction X. It is then determined whether both sides of the tilted end of the circuit board 530 fall into the elongated hole 610 based on the re-collected image. If only one side edge of the tilted end of the circuit board 530 is located in the elongated hole 610, the middle frame moving device 300 is controlled to drive the middle frame 600 to move along the second coordinate direction Y until the tilted end of the circuit board 530 is located in the middle of the elongated hole 610 on the second coordinate, and a first signal is sent to the controller.

It should be pointed out again that, the detection algorithm that the edge detection module adopted belongs to prior art, does not belong to the utility model discloses a protection content, the utility model discloses whether the purpose that just utilizes detection device 400 to realize detecting the perk end of rectangular hole 610 and circuit board 530 and align. Moreover, the present invention can also adopt other detecting devices 400 in the prior art to detect whether the tilting ends of the strip hole 610 and the circuit board 530 are aligned.

And 4, step 4: the middle frame 600 is driven to descend by the middle frame moving device 300 until the middle frame 600 is attached to the back side of the screen 510. During the descending process of the middle frame 600, when the middle frame 600 descends to a position between the first clamping claw disk 212 and the second clamping claw disk 213, the second clamping claw disk 213 is controlled to extend to clamp the circuit board 530, the first clamping claw disk 212 is controlled to retract to avoid the middle frame 600, and then the middle frame moving device 300 is continuously controlled to drive the middle frame 600 to descend.

And 5: the circuit board 530 is driven by the circuit board turnover device to continue to turn over until the circuit board 530 is attached to the back side of the middle frame 600, the circuit board turnover device is driven to release the circuit board 530 and restore to the initial position, and the middle frame moving device 300 is driven to release the middle frame 600 and restore to the initial position. Thus, the assembly process of the screen assembly and the middle frame 600 is completed once.

The above detailed description of the embodiments of the present invention is not limited to these specific embodiments, and those skilled in the art can make various modifications and modified embodiments based on the idea of the present invention, and these modifications and modified embodiments should fall within the scope of the claimed invention.
