[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] The position adjustment mechanism 3 is installed on the base 1 and is set up just above the sheet placement table 2;

[0053] The flip mechanism 4 can be moved horizontally in the front-to-back direction and vertically in the up-down direction above the sheet placement table 2 through the position adjustment mechanism 3;

[0054] The flipping mechanism 4 includes at least two flipping assemblies 41 and at least two clamping assemblies 42. The clamping assemblies 42 are respectively installed at the output ends of the flipping assemblies 41 in a one-to-one correspondence. The clamping assemblies 42 are used to clamp or release the sheet from the upper and lower directions. The flipping assembly 41 is used to drive the clamping assemblies 42 to flip 180 degrees.

[0055] The avoidance area 20 is used to avoid the clamping jaw assembly 42 .

[0056] In order to solve the technical problem of slow sheet flipping speed in the prior art, the present technical solution proposes a fully automatic sheet flipping device, such as Figure 1-4 As shown, the device comprises a base 1, a sheet placement platform 2, a position adjustment mechanism 3 and a flipping mechanism 4. The sheet placement platform 2 is used to place the sheet, and the flipping mechanism 4 can be moved horizontally in the front-to-back direction and vertically in the up-down direction through the position adjustment mechanism 3 above the sheet placement platform 2, so that the position adjustment mechanism 3 can adjust the relative position between the sheet to be flipped and the flipping mechanism 4 according to the relative position of the sheet to be flipped and the flipping mechanism 4, so that the relative position between the flipped sheet and the flipping mechanism 4 is appropriate, which is conducive to improving the accuracy of the flipping of the sheet. In addition, the position adjustment mechanism 3 can adjust the vertical displacement of the flipping mechanism 4 according to the length of the sheet, ensuring the smooth flipping of the sheet, while improving the applicability of the device.

[0057] At the same time, an escape area 20 is left between the sheet placement surface of the sheet placement table 2 and the top of the base 1, and the escape area 20 is used to avoid the clamping claw assembly 42, ensuring that the clamping claw assembly 42 has enough flipping space to smoothly grasp and flip the sheet.

[0059] The working process of the technical solution is as follows: according to the relative position of the sheet to be turned over and the clamping jaw assembly 42, the horizontal position and vertical position of the turning assembly 41 are adjusted by the position adjustment mechanism 3, thereby adjusting the horizontal position and vertical position of the clamping jaw assembly 42. When the relative position of the clamping jaw assembly 42 and the sheet is appropriate, the clamping jaw assembly 42 clamps the sheet, and the position adjustment mechanism 3 adjusts the vertical position of the turning assembly 41 and the clamping jaw assembly 42, thereby adjusting the vertical position between the sheet clamped by the clamping jaw assembly 42 and the sheet placement table 2. When the position between the sheet and the sheet placement table 2 is half the length of the sheet, the position adjustment mechanism 3 stops moving, and the flip assembly 41 drives the clamping jaw assembly 42 to flip, completing the 180° flipping of the sheet; then the position adjustment mechanism 3 adjusts the vertical position of the flip assembly 41 and the clamping jaw assembly 42 again, thereby adjusting the vertical position between the sheet and the sheet placement table 2. When the vertical position between the sheet and the sheet placement table 2 is in the same horizontal plane, the clamping mechanism 42 releases the sheet and places the sheet on the sheet placement table 2 to achieve the resetting of the sheet.
