[0003] In view of this, an object of the present invention is to provide a material supply device having the advantage of higher transfer efficiency.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a material feeding device, including a main frame and a manipulator, the two opposite sides of the main frame are an operating side and a waiting side respectively, the manipulator is arranged at a position on the upper end of the main frame close to the operating side, and also includes a traction trolley arranged on the waiting side, and a plurality of storage plates are arranged on the inner side of the traction trolley at equal intervals from top to bottom, and the plurality of storage plates are all slidably connected to the traction trolley, a traction platform is provided at the upper end of the main frame close to the waiting side, and a traction mechanism is provided at the upper end of the traction platform, and the traction mechanism is used to pull the storage plates to move between the traction platform and the traction trolley, and a lifting mechanism is provided on the inner side of the main frame close to the waiting side, and the output end of the lifting mechanism is connected to the traction platform to drive the traction platform to slide up and down.

[0005] According to the above technical solution, the first step is to place the workpiece to be processed on the upper end of the storage plate. The second step is to push the traction trolley so that the traction trolley contacts the waiting side of the main frame. The third step is to drive the traction platform to slide in the vertical direction through the lifting mechanism so that the traction mechanism is opposite to one of its storage plates. The fourth step is to pull the storage plate above the traction platform through the traction mechanism. The fifth step is to use the manipulator to clamp the workpiece to be processed and place it in the processing equipment. The sixth step is to wait until the workpiece is processed, and then use the manipulator to clamp the workpiece in the processing equipment and place it on the upper end of the storage plate. Then, the fifth and sixth steps are repeated until all the workpieces on the storage plate are processed.

[0006] Preferably, the traction mechanism includes a traction power member arranged at the upper end of the main frame, a traction seat arranged at the output end of the traction power member, and a traction boss arranged at the upper end of the traction seat. The traction power member is used to drive the traction seat to move closer to or away from the traction trolley. A traction through hole for inserting the traction boss is provided through the position of the storage plate close to the operating side.

[0007] Through the above technical solution, when it is necessary to tow the storage plate to move, the first step is to drive the traction platform downward through the lifting mechanism so that the upper end of the traction boss is lower than the lower end of the storage plate. The second step is to drive the traction seat to move toward the bottom of the storage plate through the traction power member until the traction boss is located directly below the traction through-hole. The third step is to drive the traction platform upward through the lifting mechanism until the traction boss passes through the traction through-hole.

[0010] Preferably, a plurality of support units are arranged at equal intervals from top to bottom on the inner side of the traction trolley, and the storage plate is mounted on the upper end of the support unit. The support unit includes two support plates symmetrically arranged on the inner side of the traction trolley, and a guide slope 1 is arranged at a position close to the waiting side on the upper end of the storage plate, and the guide slope 1 is arranged to be inclined upward.

[0014] Preferably, mounting plates are provided on both sides of the traction platform, and a plurality of supporting wheels are evenly provided on the side walls of the mounting plates along the sliding direction of the storage plate.

[0015] Through the above technical solution, the supporting wheels can support the storage plate and reduce the friction force on the storage plate when it moves above the traction platform, making the placement and removal of the storage plate smoother.

[0016] Preferably, two guide blocks are symmetrically provided at the lower end of the main frame near the waiting side, and two guide columns are arranged side by side at the lower end of the traction trolley. When the traction trolley collides with the main frame, the two guide columns respectively press against the two guide blocks.

[0017] Through the above technical solution, the guide block cooperates with the guide column to limit the relative movement of the traction trolley and the main frame, making the connection between the traction trolley and the main frame more stable.

[0018] Preferably, a second guiding slope is provided at the end of the guide block, and the distance between the two second guiding slopes gradually increases toward the side away from the main frame.

[0019] Through the above technical solution, the second guiding slope can guide the traction trolley to dock with the main frame, making the docking process of the traction trolley more convenient.

When the movable rod is pushed downward, the lower end of the limiting column passes through the corresponding limiting hole.

[0021] Through the above technical solution, when the movable rod is pushed downward, the lower end of the limit column passes through the corresponding limit hole to limit the relative position of the storage plate and the traction trolley. In this way, during the movement of the traction trolley, it is not easy for the storage plate to separate from the traction trolley.

[0022] Preferably, an operating hole arranged in a vertical direction is opened on the side wall of the traction trolley, an operating rod is provided on the side wall of the movable rod, and the operating rod passes through the operating hole. A locking mechanism is provided on the side wall of the traction trolley, and when the movable rod is pushed downward by the operating rod, the locking mechanism can lock the operating rod to a limited position.
