[0024] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0025] Reference Figure 1-4 , an embodiment of a sheet workpiece feeding device of the utility model is proposed:

[0026] A sheet workpiece feeding device includes a linear conveying device 2 for conveying sheet workpieces 1 forward. A silo 3 is provided above the rear end of the linear conveying device 2, and a plurality of sheet workpieces 1 are stacked in the silo 3. The bottom of the silo 3 is a discharge port 31. A card picking device 4 is provided between the discharge port 31 and the linear conveying device 2, and the card picking device 4 is used to pick the sheet workpiece 1 located at the discharge port 31 onto the linear conveying device 2.

[0027] Compared with the prior art of grabbing the sheet workpiece 1 by a suction cup or a robot, the utility model uses a card picking device 4 to pick the sheet workpiece 1 located at the discharge port 31 onto the linear conveying device 2, and the picking speed is fast, thereby improving the loading speed of the sheet workpiece 1.

[0028] like Figure 1 As shown, the cross section of the silo 3 in the horizontal direction is consistent with the shape of the sheet workpiece 1. The card picking device 4 includes a pick plate 41 and a rotating mechanism 42 located at the rear end of the material discharge port 31. The rear end of the pick plate 41 is provided with a rotating shaft 43 extending in the left-right direction, and the rotating mechanism 42 is connected to the rotating shaft 43 in a transmission manner. The rotating mechanism 42 is used to drive the pick plate 41 to rotate around the rotating shaft 43.

[0029] The linear conveying device 2 includes a frame, an annular conveyor belt 21 , and a conveying mechanism installed on the frame. The conveying mechanism is used to drive the annular conveyor belt 21 to rotate. The contact surface between the annular conveyor belt 21 and the sheet workpiece 1 is rough.

[0030] Specifically, the linear conveyor 2 includes two annular conveyor belts 21 , and the frame includes two vertical plates 23 symmetrical along the left-right direction; the two annular conveyor belts 21 are respectively arranged on the two vertical plates 23 , and the conveying mechanism is used to drive the two annular conveyor belts 21 to rotate synchronously.

[0031] A plurality of positions are arranged at equal intervals on one side of the circular conveyor 21 facing the sheet workpiece 1. The positions on the two circular conveyor 21 correspond to each other in the left-right direction, and the two corresponding positions in the left-right direction constitute a workpiece slot 25. The position is composed of two positioning protrusions 24, and the structure is simple. The distance between the two positioning protrusions 24 of the same position is consistent with the length of the sheet workpiece 1 in the front-to-back direction, and the distance between the two vertical plates 23 is consistent with the length of the sheet workpiece 1 in the left-to-right direction, so that the size of the workpiece slot 25 is consistent with the size of the sheet workpiece 1, and the distance between the two vertical plates 23 can be adjusted to make the linear conveyor 2 adapt to sheet workpieces 1 of different sizes, thereby improving the applicability of the sheet workpiece feeding equipment.

[0032] like Figure 3 As shown, the transmission mechanism includes a plurality of synchronous wheels 26 and a synchronous motor mounted on two vertical plates 23, and the annular conveyor belt 21 is wound around the outer periphery of the synchronous wheels 26. The synchronous motor extends in the left-right direction and is drivingly connected to each synchronous wheel 26 on the two vertical plates 23.

[0033] The feeding process of the utility model is as follows: Figure 3-4 As shown, first, the rotating mechanism 42 drives the paddle plate 41 to rotate around the rotating shaft 43, so that the paddle plate 41 tilts downward, and the sheet workpiece 1 located at the discharge port 31 falls under the action of gravity, and the front part of the sheet workpiece 1 first contacts the annular conveyor belt 21, and the rear part of the sheet workpiece 1 is still in contact with the paddle plate 41. Then, the rotating mechanism 42 drives the paddle plate 41 to rotate in the opposite direction. During the process of the paddle plate 41 rotating in the opposite direction, since the annular conveyor belt 21 keeps moving forward and the front part of the sheet workpiece 1 contacts the annular conveyor belt 21, the friction force of the annular conveyor belt 21 on the sheet workpiece 1 will drive the sheet workpiece 1 forward, so that the sheet workpiece 1 finally separates from the paddle plate 41, and at the same time, the paddle plate 41 returns to a horizontal state to support the sheet workpiece 1 located in the silo 3, and the above process is repeated, so that the sheet workpiece 1 is sequentially sent to the conveying device without overlapping. The paddle plate 41 rotates for a shorter distance each time, thereby increasing the speed of the paddle device 4 sending the sheet workpiece 1.

[0034] like Figure 1As shown, the silo 3 is tilted forward relative to the vertical direction, so that the stacked sheet workpieces 1 are also tilted. When the paddle plate 41 tilts downward, the sheet workpiece 1 located at the discharge port 31 is not supported by the wall of the silo 3, while the sheet workpiece 1 located in the silo 3 is supported by the tilted wall of the silo 3, so that the sheet workpiece 1 located at the discharge port 31 will fall faster than the sheet workpiece 1 located in the silo 3, which is further conducive to achieving non-overlapping material delivery. The silo 3 includes a front side 32 and a left side 33 and a right side 34 located on the left and right sides of the front side 32, respectively. The front side 32, the left side 33 and the right side 34 are integrally formed, and a bracket 27 is provided on the top of the frame. The top of the front side 32 is fixedly connected to the bracket 27, and the bottom of the left side 33 and the bottom of the right side 34 are respectively connected to the tops of the two vertical flat plates 23, so that the silo 3 is stably mounted on the frame.

[0035] The rear side of the silo 3 is open, so that the sheet-like workpieces 1 can be stacked in the silo 3. The paddle plate 41 is provided with a support block 44 located at the rear side of the silo 3, for supporting the obliquely stacked sheet-like workpieces 1.

[0036] The two vertical plates 23 are both provided with mounting members 28, and the mounting members 28 are provided with mounting holes for being movably connected with the rotating shaft 43. Since the paddle plate 41 does not need to rotate 360 ​​degrees, the rotating mechanism 42 of the utility model is a cylinder, which is cheaper than a motor. One end of the rotating shaft 43 is provided with a connecting member for connecting with the output end of the cylinder.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
