DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0018] A material taking manipulator, such as Figure 1-Figure 4 As shown, it includes a storage plate 1, a bracket 2, a first motor 3, a coupling 4, a screw 5, a guide rod 6, a movable block 7, a first cylinder 8 and a material-removing mechanism. The top of the storage plate 1 is fixedly connected with the bracket 2 on both the left and right sides. The first motor 3 is installed on the top of the left bracket 2. The screw 5 is connected between the output shaft of the first motor 3 and the right bracket 2. The first motor 3 is connected to the screw 5 through the coupling 4. The screw 5 is rotatably connected to the right bracket 2. The movable block 7 is threadedly connected to the screw 5. Two guide rods 6 are fixedly connected between the tops of the left and right brackets 2. The two guide rods 6 both penetrate the movable block 7. The bottom of the movable block 7 is fixedly connected with the first cylinder 8, and the material-removing mechanism is fixedly connected to the piston rod of the first cylinder 8. When grabbing the material on the storage plate 1, the first motor 3 rotates the screw rod 5 through the coupling 4, and the rotation of the screw rod 5 drives the movable block 7 to move along the guide rod 6, and the first cylinder 8 drives the material picking mechanism to move downward. When the material picking mechanism is close to the storage plate 1, the material picking mechanism is used to grab the material. After the material picking is completed, the first cylinder 8 is used to move the material picking mechanism upward to reset the material picking mechanism. The material picking mechanism can be flexibly moved to make the grabbing of materials more convenient.

[0019] like Figure 1-Figure 4 As shown, the material picking mechanism includes a material picking box 9, a material picking plate 10, a second motor 12, a first connecting rod 13 and a second connecting rod 14. The material picking box 9 is fixedly connected to the piston rod of the first cylinder 8, the left side of the material picking box 9 is open, the left side of the material picking box 9 is rotatably connected to the material picking plate 10, the second motor 12 is installed on the front side of the material picking box 9, the first connecting rod 13 is connected to the output shaft of the second motor 12, the front side of the material picking plate 10 is rotatably connected to the second connecting rod 14, the first connecting rod 13 and the second connecting rod 14 are rotatably connected, the left side of the inner bottom surface of the material picking box 9 is higher than the right side, which can prevent materials from falling out of the material picking box 9. When it is necessary to grab the material in the picking box 9, the second motor 12 drives the picking plate 10 to rotate downward through the first connecting rod 13 and the second connecting rod 14, so as to transfer the material into the picking box 9, and the material can be stored in the picking box 9. Then the picking plate 10 is rotated upward and reset to complete the grabbing of the material. After the material is picked up, the first cylinder 8 drives the picking box 9 to move upward away from the material on the storage plate 1 to prevent the picking box 9 from colliding with the material when moving. Then the first motor 3 is used to move the picking mechanism to other positions to grab more materials. When grabbing the material for the second time, the second motor 12 is used again to drive the picking plate 10 to rotate downward to transfer the material into the picking box 9. It is possible to grab multiple materials at one time, and the material can be grabbed into the picking box 9 multiple times, so that the picking efficiency of the manipulator is improved.

[0020] like Figure 1-Figure 4As shown, it also includes a hook plate 11 and a shovel plate 15. The hook plate 11 is fixedly connected to the bottom of the left side of the material picking plate 10, and the shovel plate 15 is fixedly connected to the bottom of the left side of the material picking box 9. When the material picking mechanism approaches the storage plate 1, the material picking mechanism is moved to the left to allow the material to accumulate on the top surface of the shovel plate 15, and then the second motor 12 drives the material picking plate 10 to rotate to transfer the material on the shovel plate 15 into the material picking box 9, ensuring that the material picking plate 10 can transfer multiple materials at one time. When the material picking plate 10 rotates, the hook plate 11 will contact the material and hook the material to prevent the material from sliding out from the front and rear ends of the material picking plate 10 when picking the material.

[0021] like Figure 1-Figure 4 As shown, it also includes a second cylinder 16, a connecting rod 17 and a discharge plate 18. The second cylinder 16 is fixedly connected to the top of the material box 9. The second cylinder 16 is a rodless cylinder. The connecting rod 17 is fixedly connected to the piston of the second cylinder 16. The bottom of the connecting rod 17 is fixedly connected to the discharge plate 18. The discharge plate 18 is slidably connected to the inner side of the material box 9. The second cylinder 16 is tilted from left to right. A strip groove is opened on the top of the material box 9. The connecting rod 17 is slidably connected in the strip groove. When the material in the material box 9 is full, it is necessary to take the material out of the material box 9. The second cylinder 16 is used to make the connecting rod 17 drive the unloading plate 18 to move along the strip groove. The unloading plate 18 is close to the shovel plate 15 to move out the material in the material box 9, thereby completing a unloading operation. After the unloading is completed, the second cylinder 16 is used to reset the unloading plate 18 away from the shovel plate 15, so as to realize the unloading operation of the manipulator. After the material in the material box 9 is emptied, it is convenient for the manipulator to take the next round of materials.

[0022] like Figure 3 As shown, a pressure sensor 19 is also included, and the pressure sensor 19 is fixedly connected to the bottom of the inner side of the material taking box 9. The pressure sensor 19 is used to detect the weight of the material in the material taking box 9. When the material is loaded in the material taking box 9, the weight of the material is measured by the pressure sensor 19, and then it is determined whether it is necessary to start the second cylinder 16 to take out the material in the material taking box 9, so as to prevent the material from being accumulated too much in the material taking box 9 and falling out of the material taking box 9.

[0023] like Figure 1-Figure 4 As shown, the first cylinder 8 is a rotary downward pressure cylinder. After the material is filled in the material box 9, when the material in the material box 9 needs to be moved to the unloading point, the first motor 3 is used to move the material taking mechanism above the unloading point, the first cylinder 8 is used to rotate the material taking mechanism, and then the unloading plate 18 is used to move the material out of the material box 9. The first cylinder 8 can rotate the material taking mechanism to any angle, so as to facilitate the movement of the material to the unloading point, further increasing the flexibility of the material taking mechanism.

[0024] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
