Simultaneously, this utility model provides two parallel loading mechanisms, and the picking and placing mechanism can move horizontally between the discharge ends of the two loading mechanisms.

On this basis, the vertical position of the limiting block can be adjusted up and down relative to the vertical slide bar, thereby adapting to LCD panels of various sizes and having good compatibility.

[0017] This utility model discloses a dual-station alternating feeding device for liquid crystal panels, combined with Figures 1 to 3 As shown, it includes two parallel feeding mechanisms 1, a picking and placing mechanism 2, and a flat placement mechanism 3. The picking and placing mechanism 2 is used to pick up the LCD panels 100 from the discharge end of the feeding mechanism 1 and place them one by one into the flat placement mechanism 3. The feeding mechanism 1 includes a conveyor belt 10 and a drive mechanism 11 for driving the conveyor belt 10 to operate. Multiple LCD panels 100 stacked in front and behind are placed on the conveyor belt 10. Two pusher blocks 12 are fixed on the conveyor belt 10 and arranged symmetrically from left to right. The pusher blocks 12 abut against the rear side of the multiple LCD panels 100. Two vertical slide rods 13 are provided at the discharge end of the feeding mechanism 1. The vertical slide rods 13 are provided with adjustable vertical position limiting blocks 14. The limiting blocks 14 include a stop block 15 extending towards the front side of the multiple LCD panels 100.

[0018] In the above structure, the picking and placing mechanism 2 includes a horizontal moving mechanism, a lifting mechanism at the moving end of the horizontal moving mechanism, a rotating mechanism at the moving end of the lifting mechanism, and a suction component at the moving end of the rotating mechanism. Based on the horizontal moving, lifting, and rotating movements, the picking and placing mechanism 2 drives the suction component to pick up the LCD panels 100 from the discharge end of the feeding mechanism 1 and place them one by one onto the flattening mechanism 3. Then, it moves above the flattening mechanism 3, placing the LCD panels 100 one by one horizontally onto the flattening mechanism 3 for subsequent processing. Simultaneously, this invention provides two parallel feeding mechanisms 1, and the picking and placing mechanism 2 can move horizontally between the discharge ends of the two feeding mechanisms 1. When multiple LCD panels 100 in one feeding mechanism 1 are fully loaded... When the material is picked up, the picking and placing mechanism 2 can move to the discharge end of the adjacent feeding mechanism 1 to pick up the material, thereby realizing the function of alternating feeding at two workstations. Compared with the prior art, this utility model does not require stopping the machine to change materials and can ensure the continuity of material supply. In addition, this utility model has a sloping part 150 at one end of the stop block 15 facing the front side of the liquid crystal panel 100. Under the blocking of the sloping part 150, the front side of the liquid crystal panel 100 can be tilted backward as much as possible, avoiding the liquid crystal panel 100 from tilting forward and causing the material picking failure. On this basis, the vertical position of the limiting block 14 can be adjusted up and down relative to the vertical slide bar 13, thereby adapting to the liquid crystal panel 100 of various sizes and having good compatibility.

[0019] As a preferred embodiment, the front end of the pusher block 12 is formed with a trapezoidal end 120, and the front end surface of the trapezoidal end 120 is aligned with the rear side surface of the plurality of liquid crystal panels 100.

[0020] In order to make the left and right push blocks 12 move synchronously, in this embodiment, two parallel fixed support rods 121 are connected between the left and right push blocks 12.

The feeding bracket 16 provides reliable support for the feeding mechanism 1.

[0023] Based on this, limiting slide bars 17 are fixed on the feeding brackets 16 on both sides of the conveyor belt 10. The limiting slide bars 17 extend along the length of the conveyor belt 10, and the sides of the multiple liquid crystal panels 100 slide in cooperation with the limiting slide bars 17. The limiting slide bars 17 are used to limit the movement of the multiple liquid crystal panels 100 from the side. Based on the sliding cooperation between the limiting slide bars 17 and the sides of the multiple liquid crystal panels 100, the multiple liquid crystal panels 100 can be smoothly conveyed forward.
