When the tooling plate 20 loaded with the assembly part 60 passes through the assembly line 10, it will be blocked by the raised stopper 72 on the right and stop. The seventh driving member 71 on the left drives the stopper 72 thereon to rise from the gap between the corresponding two rollers 14 to prevent the next tooling plate 20 from entering the equipment.

The outer diameter of the first screw rod 5371 can be increased or decreased as needed. For example, the outer diameter of the position with external threads in the first screw rod 5371 is greater than the outer diameter of the position without external threads. The two first nuts 5372 are rotatably installed on the two external threads respectively. The two first nuts 5372 on the first ball screw transmission pair 537 are arranged in upper and lower positions, and each first The two first nuts 5372 in the ball screw transmission pair 537 can rotate towards or in opposite directions.

When the adjustment of the adjustment module 53 is completed, the friction between the block 57 and the first screw rod 5371 can be increased by tightening the locking rod 56 to prevent the first screw rod 5371 from rotating relative to the inner frame 52.

[0052] The adjustment module 53 also includes a handle 58, which is installed on one of the first screw rods 5371. The first screw rod 5371 can be rotated by the handle 58, and then the other first screw rods 5371 are driven to rotate simultaneously through the cooperation of the annular synchronous belt 535 and the synchronous wheel 536.

[0057] The method of using the screen flipping device includes the following steps:

[0058] Step S101, positioning of the assembly 60: first, the tooling plate 20 packaged with the assembly 60 flows into the designated station through the assembly line 10. When the radio frequency device 15 detects that the tooling plate 20 packaged with the assembly 60 reaches the designated position, the seventh driving members 71 of the two blocking mechanisms 70 sequentially drive the stoppers 72 thereon to rise from the gap between the corresponding two rollers 14, thereby limiting the tooling plate 20 packaged with the assembly 60 and preventing the next tooling plate 20 from entering;

[0059] Step S102, the assembly 60 is turned over; the lifting mechanism 40 at the bottom lifts up the tooling plate 20 loaded with the assembly 60 through the first support rod 43, the lifting mechanism 30 drives the flipping mechanism 50 to descend to the specified position, the first clamping assembly 533 in the adjustment module 53 clamps the lifted first support rods 43, and the lifting mechanism 30 drives the flipping mechanism 50, the first support rod 43 and the tooling plate 20 loaded with the assembly 60 to move upward to the flipping position, and the first support rod 43 and the tooling plate 20 can be adjusted by rotating the handle 58 in the adjustment module 53. The position of the second support rod 54 is adjusted to adjust the gap between the two support pads 21 to achieve the function of adapting to the thickness of the fixed assembly 60. The second driving member 51 then drives the first support rod 43, the inner frame 52, the adjustment module 53, the second support rod 54 and the tooling plate 20 loaded with the assembly 60 to flip 180 degrees, so that the tooling plate 20 loaded with the assembly 60 is turned over. At this time, the second support rod 54 is located below the first support rod 43, and the upper and lower positions of the two support pads 21 are swapped to complete the action of flipping the assembly 60.

[0060] Step S103, the assembly 60 returns to its original position; when the turning over is completed, the lifting mechanism 30 drives the flipping mechanism 50, the first support rod 43 and the tooling plate 20 loaded with the assembly 60 to move downward to the specified position, the adjusting module 53 releases the second support rod 54 on the raised top block 42, and finally the first driving member 41 returns the tooling plate 20 loaded with the assembly 60 to the assembly line 10 through the second support rod 54, and the blocking mechanism 70 is reset.

[0061] In summary, when turning over a large-sized assembly 60, the utility model can use a screen-turning device to replace traditional manual labor, and the tooling plate 20 loaded with the assembly 60 can be turned 180 degrees on the assembly line 10, which is convenient for online assembly of both sides of the assembly 60 on the assembly line 10, greatly reducing the intensity and repeatability of manual operation, reducing production personnel, and there is no risk of bumping on the surface of the assembly 60, which can meet the needs of high-efficiency and high-quality production and is convenient for large-scale promotion.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
