Technical Field

[0001] The present invention relates to the technical field of turnover pallets, and mainly relates to an angled structure of a turnover pallet for LCD screens. Background Art

[0002] LCD screens are increasingly used in the electronics industry, across a wide range of applications, including digital products, automotive applications, and machine tools. Turnover pallets are essential during the production and assembly of LCD screens. Due to the narrow and ultra-thin bezels of today's LCD screens, and the ease with which LCD screens are placed on the outer edges of the pallet slots, there is a risk of cracking the LCD glass during the turnover process.

[0003] Existing turnover pallets are difficult to protect LCD screens placed on the edge of the slot. When an LCD screen is placed on the edge of the turnover pallet slot and personnel do not notice and directly stack turnover pallets on top of each other, the LCD screen will be crushed, resulting in an increase in the defective rate of the LCD screen and increased manufacturing costs. Therefore, it is necessary to design an angled structure for a turnover pallet for LCD screens to solve the above problems. Summary of the Invention

[0007] In the present invention, the outer included angle of 68° between the bevel and the bottom surface of the tray makes it easier for the LCD screen to slide down, the weight sensor facilitates detecting whether the LCD screen is flat, and the electric telescopic rod and the pneumatic telescopic rod respectively raise the first sliding device and the second sliding device to adjust the LCD screen.

[0008] Furthermore, the position adjustment detection mechanism also includes a screw connected to the bottom of the plug plate, a rotating motor connected to one side of the screw, a base connected to the bottom of the rotating motor and a pneumatic cylinder connected to both sides of the bottom of the base.

[0009] In the present invention, the screw rod facilitates the removal of the inserting plate from the bottom of the tray, and the pneumatic cylinder facilitates the adjustment of the position of the inserting plate, so as to detect and adjust the LCD screens in the trays at different heights.

[0010] Furthermore, the supporting shock absorbing device includes a plurality of second telescopic members connected to the top of the tray and a second spring sleeved on the outer wall of the second telescopic member.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] First, the present invention is equipped with a position adjustment detection mechanism. When the LCD screen contacts the first roller and the second roller, the first spring is compressed, causing the first slider and the second slider to contact the weight sensor. The weight sensor determines whether the LCD screen is flat by measuring whether the weight is uniform. If it is not flat, the electric telescopic rod or the pneumatic telescopic rod is extended to raise the first roller or the second roller, thereby sliding the LCD screen to adjust its position. The side of the tray is also configured as a beveled edge, allowing the LCD screen to slide down automatically. The angle between the beveled edge and the bottom surface is 68 degrees, which is more conducive to the sliding of the LCD screen and avoids the phenomenon of the LCD screen being crushed when the trays are stacked on top of each other, which leads to an increase in the defective rate of the LCD screen.

[0030] Secondly, the present invention makes the LCD screen easier to slide by providing the first roller, the second roller and the third roller, thereby avoiding as much as possible the friction between the LCD screen and the tray that causes many scratches on the LCD screen, thereby improving the quality of the LCD screen.

[0053] It should be noted that, in the embodiment, the second roller 61 is more conducive to the sliding of the LCD screen 80 , and the second roller 61 and the first roller 51 are perpendicular to each other to facilitate the adjustment of the LCD screen 80 in different directions.

[0054] For example, please refer to the attached Figure 2 and Figure 7 A retaining wall 21 is provided on the side of the tray 20 , and a supporting shell 24 is fixed to the bottom of the tray 20 . The lower surface of the inner part of the supporting shell 24 is connected to the first telescopic member 71 .

[0055] It should be noted that, in the embodiment, the retaining wall 21 is used to limit the position of the tray 20 , and the supporting shell 24 is used to fix one end of the first telescopic member 71 .

[0056] For example, please refer to the attached Figure 2 The inner side of the oblique edge 22 is rotatably connected to a plurality of third rollers 23 of different lengths.

[0057] It should be noted that, in the embodiment, the third roller 23 is more conducive to the LCD screen 80 sliding down along the oblique edge 22 .
