[0038] Anti-slip component 7 is disposed inside the connecting plate 1. The anti-slip component 7 includes a sliding plate 71, a connecting rod 72, a return spring 73, and a baffle 74.

[0039] There are two connecting plates 1, which are movably connected to the two ends of the first limiting plate 32.

The suspension rod 23 is S-shaped, and the top of the rear end is fixedly connected to the bottom of the support plate 22. By extending and retracting the hydraulic rods 21, the support plate 22 can drive the suspension rod 23 to move up and down, which makes it convenient for the staff to hang the front frame on the suspension rod 23.

[0040] The bidirectional threaded rod 31 is movably embedded inside the connecting plate 1, the two ends of the first limiting plate 32 are threadedly connected to the surface of the bidirectional threaded rod 31, and the first drive motor 33 is fixedly connected to one end of the bidirectional threaded rod 31.

[0041] Two grooves are provided on the inner surfaces of both connecting plates 1. The bidirectional threaded rod 31 is rotatably connected to the inside of the top groove of the rear connecting plate 1. A rod is fixedly connected to the inside of the other grooves. Two sliders are fixedly connected to the front and rear ends of the first limiting plate 32. The two sliders at the front and rear ends of the two first limiting plates 32 are respectively movably embedded in the grooves on the surfaces of the two connecting plates 1, and are respectively threaded to the surface of the bidirectional threaded rod 31 and slidably sleeved on the outer surface of the connecting rod. Starting the first drive motor 33 can drive the bidirectional threaded rod 31 to rotate, and the sliders will drive the two first limiting plates 32 to move towards each other or relative to each other, so as to limit the front frame of different sizes.

[0043] The electric telescopic rod 41 is fixedly connected to the outer surface of the front connecting plate 1. A hole is opened on the front surface of the suspension rod 23. One end of the fixing plate 42 is embedded in the hole, thereby achieving a seal at the bottom of the suspension rod 23. By pulling the fixing plate 42 to the front end through the electric telescopic rod 41, a gap is created between the suspension rod 23 and the inner surface of the front connecting plate 1. At this time, the gripper can grip the front frame.

[0044] The two ends of the rotating threaded rod 51 are movably connected to the surface of the connecting plate 1, the push plate 52 is threadedly connected to the outer surface of the rotating threaded rod 51, and the second drive motor 53 is fixedly connected to one end of the rotating threaded rod 51.

[0045] The left and right ends of the rotating threaded rod 51 are rotatably connected to the surfaces of the two connecting plates 1 near the left end, respectively. A rod is fixedly connected to the inner surface of the two connecting plates 1 near the right end. Each of the surfaces of the two first limiting plates 32 has an opening. The two ends of the pushing plate 52 are respectively connected to the outer surface of the rotating threaded rod 51 by two threads and slidably connected to the outer surface of the connecting rod.

[0047] The support frame 61 is fixedly connected to the outer surface of the front connecting plate 1, the adjusting threaded rod 62 is rotatably connected to the inner surface of the support frame 61, and the second limiting plate 63 is movably embedded inside the support frame 61. When the adjusting threaded rod 62 is rotated, the support frame 61 limits the adjusting threaded rod 62, and the adjusting threaded rod 62 moves back and forth.

[0048] The sliding plate 71 is movably sleeved on the outer surface of the adjusting threaded rod 62, one end of the connecting rod 72 is fixedly connected to the surface of the sliding plate 71, the return spring 73 is movably sleeved on the surface of the connecting rod 72, and the baffle 74 is fixedly connected to the other end of the connecting rod 72.

[0049] The sliding plate 71 is slidably sleeved on the outer surface of the adjusting threaded rod 62, and a connecting rod 72 is fixedly connected to the surface near both the left and right ends.

[0050] The working principle of the automatic feeding device for processing the front frame of a liquid crystal display screen provided by this utility model is as follows:

[0051] First, the hydraulic rod 21 is activated, which drives the suspension rod 23 upward to the top of the first limiting plate 32 via the support plate 22. Then, the front frame is hung on the suspension rod 23 in batches. Then, the hydraulic rod 21 is activated to reset, and the front frame is positioned between the two first limiting plates 32. Then, the first drive motor 33 is activated to drive the bidirectional threaded rod 31 to rotate. The two first drive motors 33 move relative to each other to a suitable position to limit the two ends of the front frame. Then, the threaded rod 62 is rotated and adjusted according to the thickness of the front frame until the second limiting plate 63 moves to a suitable position. Then, the second drive motor 53 is activated to drive the rotating threaded rod 51 to rotate. The push plate 52 moves forward and pushes the front frame to slide forward. The front frame moves along the push baffle 74 until the sliding plate 71 connects to the surface of the second limiting plate 63. The frontmost front beam falls onto the fixed plate 42 through the front end of the suspension rod 23 and the baffle 74. Finally, the electric telescopic rod 41 is activated. When the fixed plate 42 moves, the bottom of the suspension rod 23 is opened. At this time, the gripper picks up the front frame.

[0052] Compared with related technologies, the automatic feeding device for processing the front frame of a liquid crystal display screen provided by this utility model has the following advantages:

[0053] This utility model provides an automatic feeding device for processing the front frame of an LCD display screen. The hydraulic rod 21 drives the suspension rod 23 to move up and down, making it convenient for workers to hang the front frame on the suspension rod 23. At the same time, the first limiting plate 32 can clamp and limit the two ends of the front frame. The pushing plate 52 pushes the front frame to move, and the frontmost front frame can fall onto the fixed plate 42. Then, by extending and retracting the electric telescopic rod 41, the gripper picks up the front frame and moves it downward to complete the feeding. In this process, there is no need for manual placement of the front frames one by one. The operation is simple, saves manpower, and improves work efficiency.

[0058] The working principle of the automatic feeding device for processing the front frame of a liquid crystal display screen provided by this utility model is as follows:
