[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model discloses a stacker crane for transferring parts, which mainly includes a horizontally movable vehicle 16, a vertically movable lifting frame 11, a vertically movable moving frame 14, and a control system. A horizontal movement control servo geared motor 7, a vertical movement control servo geared motor 31, a pneumatic safety brake 10, a vertical movement control servo geared motor 12, and a control box 30 are connected to the control system.

[0020] The stacker crane's vehicle 16 is equipped with wheels 5 and guide rollers 4 at its lower part, as well as a horizontal movement control servo motor 7. A gear 6 for horizontal movement of the vehicle is mounted on the output end of the servo motor 7. A horizontal guide rail 1 is mounted on a track 26, and a mounting plate 28 is also fixed to the track 26. A rack 2 for horizontal movement of the vehicle is fixed to the side of the mounting plate 28. The gear 6 and the rack 2 mesh with each other, and the wheels 5 and guide rollers 4 are in a rolling connection with the horizontal guide rail 1. The rotation of the output shaft of the servo motor 7 drives the gear 6 to rotate. Through the gear 2 meshing with the gear 6, and guided by the guide rollers 4, the wheels 5 roll on the horizontal guide rail 1, achieving horizontal movement of the vehicle 16.

[0021] A lifting frame 11 is installed in the middle of the vehicle 16. Four rollers 13 for vertical movement of the lifting frame are installed on the lifting frame 11. A vertical movement control servo reduction motor 31 is fixed to the lower part of the vehicle 16. The driving sprocket is installed at the output end of the vertical movement control servo reduction motor. The driven sprocket 22 is installed on the upper part of the lifting frame 11. The driving sprocket and the driven sprocket 22 are engaged with the chain 23. The lifting frame 11 and the chain 23 are connected to the connecting plate 24 through the fixing plate 25. Four vertical guide rails 8 for the lifting frame and a pneumatic safety brake 10 are installed on both sides of the vehicle 16. In the pneumatic opening mode, the pneumatic safety brake 10 can move up and down along the safety rod 9. The safety rod 9 is fixed to the side of the vehicle 16 through the upper and lower mounting seats. The rollers 13 for vertical movement of the lifting frame are tumblingly connected to the vertical guide rails 8 of the lifting frame. The pneumatic safety brake 10 is an outsourced component with the model and specification RBPS-2400-A. The output shaft of the vertical movement control servo reducer motor 31 rotates, which drives the driven sprocket 22 to rotate through the active sprocket, thereby driving the chain 23 to move. In turn, the chain 23 drives the four lifting frames on the lifting frame 11 to move vertically. The rollers 13 roll up and down on the vertical guide rail 8 of the lifting frame, so as to realize the vertical movement of the lifting frame 11 on the vehicle 16.

[0022] The movable frame 14 of the lifting frame 11 can roll within four grooves on the inner side of the lifting frame 11 via four vertically movable rollers 19 mounted on its side. A vertical movement control servo motor 12 is mounted on the base plate of the lifting frame 11. A vertical movement gear 20 is mounted on the output end of the vertical movement control servo motor 12. A vertical movement rack 21, meshing with the vertical movement gear 20, is mounted on the lower part of the movable frame 14. A positioning support column 18 is mounted on the upper part of the movable frame 14 to lift the parts 32 to be transferred when the movable frame 14 moves to other equipment. The position of the positioning support column 18 is offset from the position of the positioning holes on the parts 32 to facilitate the movement of the layers. Part 32 on the moving layer 14 is connected to the positioning pin on other equipment. The external dimensions of part 32 are larger than the width of the moving layer 14, so that the moving layer 14 can place part 32 on the moving layer 14 to the designated position on other equipment, which facilitates the transfer of part 32. Rollers 17 and 15 are installed under the fixed rods 3 on both sides of the top of the trolley 16. Rollers 17 and 15 can roll on the guide rails 33 of other equipment. A total of four rollers on both sides clamp the guide rails 33 in the middle to provide auxiliary support for the stacker crane during the movement process, which can improve the force and prevent the stacker crane from tipping over. The stacker crane is also equipped with auxiliary parts such as drag chain 27 and 29 and control box 30. Drag chain 27 and 29 are used to place the relevant pipelines of the stacker crane. The output shaft of the vertical movement control servo reduction motor 12 drives the vertical movement gear 20 of the moving frame to rotate. Through the vertical movement rack 21 of the moving frame that meshes with the vertical movement gear 20, the moving frame 14 can be driven to move back and forth in the vertical direction along the lifting frame 11. Under the action of gravity, the part 32 and the moving frame 14 can move back and forth in the vertical direction together.

[0023] Under the control of the horizontal movement control servo reducer motor 7, the vertical movement control servo reducer motor 12, and the vertical movement control servo reducer motor 31 of the stacker crane, part 3 can move precisely in the X, Y, and Z directions in space to achieve accurate positioning of parts and objects in space. This better serves the automated equipment or flexible production line to perform turnover tasks, resulting in shorter transfer time, higher accuracy, greatly improved part transfer efficiency and automation, reduced production costs and labor intensity, reduced manual intervention and safety hazards, and improved stability and reliability of the production process.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
