DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example

[0029] like Figures 1-12 As shown, this embodiment includes a support base 1, a loading device arranged on the support base 1 for guiding the eccentric shaft from the storage position, a transfer device arranged on the support base 1 for placing the eccentric shaft in a uniform form, and a placing table 2 arranged next to the support base 1 for placing the raw material to wait for subsequent processing steps. The loading device includes a loading base 3 with an inclined surface on the top, a storage trough 4 arranged in the middle of the loading base 3 and opening toward the lower end of the inclined surface, and a stepped vertical ejector plate 5 is arranged on the inclined surface. The stepped vertical ejector plate 5 is composed of a plurality of ejector plates arranged in a stepped manner and capable of vertically moving up and down along the inclined direction of the inclined surface. A material guide rail 6 is arranged on the top of the loading base 3, one side of which is connected to the top of the inclined surface. A first drive motor 7 that can drive the material guide rail 6 to rotate is fixed to one side of the loading base 3, and a discharge extension end 8 is provided on the end of the material guide rail 6 facing the transfer device. The storage trough 4 is used to place the eccentric shaft, and the bottom surface of the storage trough 4 is inclined toward the inclined surface. The eccentric shaft placed in the storage trough 4 moves toward the inclined surface under the action of gravity until it moves to the top of the nearest ejection plate, and moves upward with the ejection plate until it slides to the top of another adjacent ejection plate. Then the eccentric shaft moves with the second ejection plate until it slides to the top of the third ejection plate. Finally, the eccentric shaft moves to the top of the inclined surface driven by the third ejection plate and falls into the guide track 6 connected to it, and moves to the discharge extension end 8 along the guide track 6.

[0030] like Figures 1-12As shown, the transfer device includes a transfer base 9, an adjustment device mounted on the transfer base 9 for adjusting the placement direction of the eccentric shaft, a lifting device for lifting the eccentric shaft in the adjustment device to a position for grasping, and a swing-arm manipulator capable of transferring the eccentric shaft in the lifting device to the loading platform 2. The adjustment device includes a support frame 10, a set of adjustment rollers 11 mounted on the support frame 10 with one end located directly below the extended discharge end 8, and a material guide member 12 mounted at the other end of the adjustment roller 11. The material guide member 12 has an eccentric shaft slot 13 mounted on its upper portion that can engage the middle portion of the eccentric shaft. The adjustment roller 11 is connected via a roller transmission and rotates toward the centerline of the two rollers. The height of the adjusting roller 11 near the discharging extension end 8 is higher than the height of the end away from the discharging extension end 8, and the distance between the two adjusting rollers 11 is smaller than the middle structure of the eccentric shaft. The center line of the guide track 6, the center line of the adjusting roller 11, and the center line of the eccentric shaft slide groove 13 are on the same straight line. Specifically, the eccentric shaft derived from the discharging extension end 8 will fall into one end of the adjusting roller 11, and then move toward the material guide piece 12 along the adjusting roller 11 that continuously rotates toward the center line of symmetry. During this movement, the eccentric shaft will flip under the action of gravity, and the end with a smaller diameter of the eccentric shaft will vertically pass through the two adjusting rollers 11 so that the entire eccentric shaft is in a state of hanging between the two adjusting rollers 11. In this state, the eccentric shaft slides into the material guide piece 12 through the clamping connection with the eccentric shaft slide groove 13 in the middle, and moves along the material guide piece 12 toward the end close to the lifting device.

[0031] like Figures 1-12 As shown, the lifting device includes a lifting base 14, a first rotating motor 15 disposed on one side of the lifting base 14, a turntable 16 connected to the first rotating motor 15 and rotatable under the drive of the first rotating motor 15, and an eccentric shaft clamp 17 connected to the turntable 16 and capable of rotating 90 degrees with the turntable. The eccentric shaft clamp 17 includes a connecting column 18 fixed to the turntable 16, U-shaped grooves 19 symmetrically fixed on both sides of the connecting column 18, and clamps 20 symmetrically arranged between the U-shaped grooves 19. The bottom ends of the clamps 20 are hinged by a rotating shaft, and a slot for inserting the eccentric shaft is provided between the clamps 20. Specifically, when the eccentric shaft clamp 17 rotates with the turntable 16 until it is parallel to the horizontal plane, the side surface of the U-shaped groove 19 and one end of the slot of the clamp 20 are facing upward and are located directly below one end of the material guide member 12. One end of the eccentric shaft guided by this end of the material guide member 12 will fall into the slot. Then the eccentric shaft clamp 17 rotates with the turntable 16 until it is perpendicular to the horizontal plane. The eccentric shaft is parallel to the horizontal plane and one end is exposed.

[0032] like Figures 1-12As shown, the swing-arm manipulator includes an operating unit 21, mounted beside the lifting base 14, for operating the loading device; a second rotary motor 22, mounted on top of the operating unit 21; a mounting frame 23 connected to and rotatable by the second rotary motor 22; a lifting chute 24, mounted within the mounting frame 23; and a robotic arm 25, mounted within the lifting chute 24 and movable along the chute 24 by a motor 28. A retractable gripper 26 is connected to the lower end of the robotic arm 25. The second rotary motor 22 drives the mounting frame 23 to rotate within a certain angle, allowing the robotic arm 25, mounted therein, to rotate within a certain range, encompassing the lifting device and above the loading platform 2. Driven by the motor, the robotic arm 25 can move vertically along the lifting chute 24, thereby adjusting the distance between the gripper 26 and the lifting device and the loading platform 2.

[0033] like Figures 1-12 As shown, the loading platform 2 is equipped with at least one set of racks 27 for accommodating eccentric shafts. Specifically, the gripper 26 rotates with the robotic arm 25 to the eccentric shaft fixture 17, grasps the exposed end of the eccentric shaft, and lifts it upward from the fixture 20. The robotic arm 25 then rotates to the corresponding rack 27, and this process is repeated to load the eccentric shaft. In this embodiment, two sets of racks 27 are provided on the loading platform 2.

[0034] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
