[0019] Reference Figure 2 and Figure 4A contact assembly 33 is provided on one side of the transverse movable seat 3 close to the rotating shaft 5.

[0020] Reference Figure 1 and Figure 2 The servo motor 6 is vertically fixed on a side plate 12 with the main shaft facing upward. A reducer 61 connected to the main shaft is provided at the main shaft end of the servo motor 6. A first gear 611 is driven on one side of the reducer 61. A second gear 53 is provided on the rotating shaft 5. The first gear 611 and the second gear 53 are sleeved with a transmission chain. The first gear 611 and the second gear 53 are linked through the transmission chain. The servo motor 6 drives the reducer 61 to operate, and the reducer 61 drives the first gear 611 to rotate. The second gear 53 is driven to rotate through the transmission chain to realize the rotation of the rotating shaft 5.
[0021] The implementation principle of the adsorption feeding mechanism for a pasting machine of the present application is as follows: the servo motor 6 drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the first cam 51 and the second cam 52 to rotate. When the convex part of the first cam 51 just abuts against the second roller 72, the suction cup 23 is in a state of pressing against the external feeding platform to adsorb the paper. The rotating shaft 5 rotates so that the convex part of the first cam 51 presses against the second roller 72 to make the V-shaped swing arm 7 swing, and the first roller 71 swings upward in an arc trajectory to make the vertical movable seat 4 slide and rise, and the vertical movable seat 4 also applies a lateral force to the vertical slide rail 32 to make the lateral movable seat 3 move toward the rotating shaft 5. During the process, the third roller 332 moves on the inclined surface 521 on the upper surface of the convex portion of the second cam 52, the vertical movable seat 4 slides and rises, and at the same time, the transverse movable seat 3 slides transversely, so that the mounting rod 21 rises in an inclined straight line trajectory, so that the suction cup 23 drives the paper to move up to the position of the coating mechanism feeding port outside the position. When the arc surface 511 of the peripheral wall of the first cam 51 abuts the second roller 72, it is the highest position of the vertical movable seat 4 sliding and rising. The vertical movable seat 4 is limited by the vertical slide rail 32 at this position. This position is the position of the feeding port of the coating mechanism outside the paper position. When the vertical movable seat 4 is in this position, the convex surface of the second cam 52 The inclined surface of the upper surface of the third roller 332 is parallel to the horizontal ground, and the third roller 332 is just pressed by the second cam 52, and continues to rotate in the same direction through the rotating shaft 5, and the arc surface 511 of the convex part of the first cam 51 abuts against the second roller 72 for movement, and the V-shaped swing arm 7 is in a stationary state. The second cam 52 presses the third roller 332 to push the horizontal movable seat 3 to move in the direction of the avoidance groove 14, and the horizontal movable seat 3 moves in the direction of the avoidance groove 14 so that the vertical movable seat 4 moves in the direction of the avoidance groove 14, so that the suction cup assembly 2 moves the paper horizontally into the external coating mechanism feed port, and when the second cam 52 rotates to make the arc surface 511 on it move out of the first roller 332, the second cam 52 moves out of the first roller 332, and the second cam 52 moves out of the first roller 332. When the second roller 72 is moved, the convex part of the second cam 52 presses down the second roller 72 again to make the horizontal movable seat 3 move in the direction of the rotating shaft 5, so that the third roller 332 moves in the direction of the rotating shaft 5 to the position acted by the convex part of the second cam 52. When the second roller 72 moves out of the convex part of the first cam 51, the vertical movable seat 4 slides down under the action of gravity and in the process of the vertical movable seat 4 descending, the third roller 332 moves in the direction of the avoidance groove 14 under the pressure of the second cam 52, so that the installation rod 21 is inclined and linearly descended. The suction cup assembly 2 moves back and forth in a "7" shape during the rotation of the rotating shaft 5 to achieve paper loading. The single servo motor 6 is used to drive the rotating shaft 5 to rotate, and the first cam 51 and the second cam 52 act on the vertical movable seat 4 and the horizontal movable seat 3 respectively to drive the suction cup assembly 2 to move and load the paper. The cost is lower than that of using at least two linear modules, and the single servo motor 6 drive does not require a complex control system, further reducing the equipment cost.
