[0039] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] Embodiment 1:

[0041] like Figure 1 and Figure 2As shown, this embodiment provides a paper picking mechanism, including a frame 1, a power member 3, a material box 2, and a transfer position. The power member 3, the material box 2 and the transfer position are sequentially arranged on the frame 1 along the paper conveying line. A transfer assembly 5 is arranged on the transfer position. The material box 2 is used to hold stacked papers. An avoidance position is opened at the bottom of the material box 2 along the paper conveying line. A feed plate 4 is arranged at the output end of the power member 3. The feed plate 4 extends along the paper conveying direction and passes through the avoidance position of the material box 2. The feed plate 4 can separate the bottom layer of paper in the material box 2 and move the paper to the transfer position. The transfer assembly 5 is used to grab the paper that follows the feed plate 4 to move to the transfer position. Specifically, stacked paper is placed in the material box 2, and the power member 3 can drive the feed plate 4 to separate the paper at the bottom layer in the material box 2. The separated paper moves to the transfer position with the feed plate 4, and the transfer component 5 grabs the paper and uses the paper to wipe the car body. In this embodiment, the feed plate 4 is used to separate the stacked paper, which can improve the paper separation efficiency and avoid the problem that the robot is easy to clamp multiple layers of paper when the robot is used to clamp the paper in the prior art, and the transfer component 5 is used to grab the paper, which can avoid the problem that the suction cup is easily blocked by the parts of the car when the suction cup is used to absorb the paper in the prior art. Optionally, the power member 3 is a cylinder.

[0042] like Figure 3 As shown, in this embodiment, the feed plate 4 includes a first plate 41 and a second plate 42, the first plate 41 is located on the side close to the power member 3, the second plate 42 is located on the side close to the transfer position, and the friction coefficient between the first plate 41 and the paper is less than the friction coefficient between the paper, and the friction coefficient between the second plate 42 and the paper is greater than the friction coefficient between the paper. Before separating the paper, the second plate 42 is located directly below the stacked paper and carries the paper. When the paper needs to be separated, the power member 3 drives the feed plate 4. Since the friction coefficient between the second plate 42 and the paper is greater than the friction coefficient between the paper, the paper at the bottom layer follows the second plate 42 to leave the material box 2. Since the friction coefficient between the first plate 41 and the paper is less than the friction coefficient between the paper, when the first plate 41 enters the material box 2, the first plate 41 will not drive the paper.

[0043] In this embodiment, the thickness of a single paper is preset to M, the horizontal position of the upper surface of the first plate 41 is higher than the horizontal position of the upper surface of the second plate 42, and a height difference is formed between the upper surface of the first plate 41 and the upper surface of the second plate 42, and the height difference is greater than zero and less than or equal to M. The bottom layer of paper is attached to the surface of the second plate 42, and since a height difference is formed between the upper surface of the first plate 41 and the upper surface of the second plate 42, and the height difference is greater than zero and less than or equal to M, it can be ensured that the bottom layer of single paper can be supported by the side of the first plate 41, so as to be separated out of the material box 2.

[0044] like Figure 4As shown, in this embodiment, the material box 2 includes a first baffle 21 and a second baffle 22. The first baffle 21 is located on a side close to the power member 3, and the second baffle 22 is located on a side close to the transfer position. The distance from the bottom surface of the first baffle 21 to the upper surface of the first plate 41 is less than M, and the distance from the bottom surface of the second baffle 22 to the upper surface of the second plate 42 is greater than or equal to M and less than 2M. The second baffle 22 can prevent multiple sheets of paper from leaving the inside of the material box 2 at the same time. When the paper is transported to the transfer position, the first plate 41 is located in the material box 2 and carries the stacked paper. When the second plate 42 needs to be returned to the material box 2, the power member 3 drives the feed plate 4 to return to the initial position. The second plate 42 contacts the bottom layer of paper in the process of entering the material box 2. The paper has a tendency to separate. The distance from the bottom surface of the first baffle 21 to the upper surface of the first plate 41 is set to be less than the thickness of the paper, which can prevent the paper from separating in the process of the feed plate 4 returning to the initial position.

[0045] like Figure 3 As shown, in this embodiment, the paper picking mechanism also includes a lifting cylinder 6 and two lifting plates 7 arranged at the output end of the lifting cylinder 6. The lifting cylinder 6 is arranged at the bottom of the frame 1. The two lifting plates 7 are respectively located on both sides of the transfer position, and the central vertical line between the two lifting plates 7 is the paper conveying line. The two lifting plates 7 can lift the two side edges of the paper and fit them to the side of the transfer component 5 to ensure the clamping of the paper and avoid deflection or falling during the process of wiping the car body.

[0046] like Figure 5 As shown, in this embodiment, the transfer assembly 5 includes a driving module 51 with two output ends, two clamping plates 52 and a laminating plate 53, the two clamping plates 52 are respectively installed at the two output ends of the driving module 51, the moving direction of the output end of the driving module 51 is horizontal and perpendicular to the conveying line of the paper on the frame 1, the laminating plate 53 is arranged on the side of the driving module 51 facing the transfer position, and the driving module 51 can drive the clamping plate 52 to clamp the side of the paper to the side of the laminating plate 53. Optionally, the driving module 51 is a cylinder.

[0047] In this embodiment, a card slot 531 is provided on one side of the laminating plate 53 facing the pressing plate 52, and the pressing plate 52 can clamp the side edge of the paper into the card slot 531, the lifting plate 7 clamps the lower part of the side edge of the paper to the side of the laminating plate 53, and the pressing plate 52 clamps the upper part of the side edge of the paper into the card slot 531 and presses it.

[0048] like Figure 3 and Figure 6As shown, in this embodiment, the paper picking mechanism also includes a connecting component 8 and a limiting component 9. The connecting component 8 is connected to the output end of the lifting cylinder 6, and the lifting plate 7 is fixedly connected to the connecting component 8. The limiting component 9 is arranged at the bottom of the frame 1 and is located on one side of the connecting component 8. The limiting component 9 is used to limit the vertical displacement of the connecting component 8 to prevent the connecting component 8 from exceeding the stroke during the process of lifting or lowering the lifting plate 7, resulting in the inability to clamp the paper.

[0049] In this embodiment, the connecting component 8 includes a connecting plate 81, and the limiting component 9 includes a first limiting member 91 and a second limiting member 92, one end of the first limiting member 91 extends above the connecting plate 81, and the second limiting member 92 is located below the connecting plate 81.

[0050] In this embodiment, a limiting through hole 93 is further provided on the limiting component 9, and a limiting column 54 is provided on the side of the transfer component 5 facing the transfer position. The limiting column 54 can be accommodated in the limiting through hole 93. When the transfer component 5 moves from the outside to the transfer position, the limiting column 54 is inserted into the limiting through hole 93, which can ensure that the transfer component 5 accurately clamps the paper.

[0051] The working process of the paper picking mechanism of this embodiment is as follows: the power member 3 drives the feeding plate 4 located at the initial position to move along the paper conveying direction, the second plate 42 transports the bottom layer of paper located in the material box 2 to the transfer position, the lifting cylinder 6 drives the lifting plate 7 to attach the lower part of the side of the paper to the bonding plate 53, the driving module 51 drives the clamping plate 52 to clamp the upper part of the side of the paper into the card slot 531, the lifting cylinder 6 drives the lifting plate 7 to descend, the lifting plate 7 is separated from the paper, and the transfer assembly 5 transfers the paper.
