Description

Technical Field

[0001] This utility model relates to the field of engine tray storage technology, specifically to an engine tray material handling device. Background Technology

[0002] The automobile engine, the heart of a car, provides power and determines its performance, fuel economy, stability, and environmental friendliness. The cylinder block and cylinder head are crucial components of the engine, and both are quite heavy. During the production and assembly of automobile engines, engine parts are placed on pallets and transported to the assembly station using AGV (Automated Guided Vehicle) transport vehicles. However, different engine models require different cylinder blocks and cylinder heads, each corresponding to a different type of pallet. Therefore, pallet transfer equipment is needed to retrieve, place, and recycle these different types of pallets within the warehouse.

[0003] During the transfer of engine pallets from AGV (Automated Guided Vehicle) transport vehicles to warehouse shelves, a hook is used to retrieve the pallets. When the AGV moves under the hook, the hook descends and hooks onto the pallet's lifting rod. The hook then rises in the opposite direction, lifting the engine pallet from the AGV. However, in some cases, the engine pallet's position on the AGV may be misaligned, such as due to bumps or collisions during movement. In these situations, the hook cannot properly align with the lifting rod, preventing automatic hooking. Current technology involves manually correcting and adjusting the misaligned pallets. This manual adjustment method suffers from low automation, low efficiency, and high labor intensity for workers. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an engine pallet picking and unloading device to solve the problems of low automation, low work efficiency and high labor intensity caused by the existing method of manually adjusting engine pallets that are placed on AGV transport vehicles with deviations in position.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides an engine pallet loading and unloading device, including a frame, and further comprising:

[0007] A lifting drive mechanism is installed on the upper end face of the frame, and the lifting drive mechanism and the top surface of the frame form a sliding connection along the conveying direction of the engine tray;

[0008] A lifting slide and a rotary drive mechanism are provided, wherein the lifting drive mechanism is connected to the lifting slide and the rotary drive mechanism and is used to drive the lifting slide and the rotary drive mechanism to move up and down.

[0009] A cylinder, the top end of which is connected to the top end of the lifting slide and the rotary drive mechanism, and the bottom end of which is fixedly mounted on the lifting drive mechanism.

[0010] A rotating and lateral lifting device includes a first base plate, four hooks fixedly installed at the corners of the bottom surface of the first base plate, a rotating base plate parallel to the top of the first base plate, a driven gear, and a lateral drive assembly. The driven gear is rotatably mounted on the bottom surface of the lifting slide and the rotating drive mechanism via a bearing seat. The first base plate is laterally slidably connected to the rotating base plate via a sliding assembly. The lateral drive assembly is connected to the first base plate. The bottom surface of the driven gear is fixedly installed on the top surface of the rotating base plate. The lifting slide and the rotating drive mechanism are meshed with the driven gear.

[0011] Furthermore, the lifting, sliding and rotating drive mechanism includes a first servo motor and a first drive gear. The first drive gear is fixedly mounted on the output shaft of the first servo motor. The first drive gear meshes with the driven large gear. The rotating base plate has an arc-shaped sliding groove that runs vertically through it. The end of the output shaft of the first servo motor is slidably mounted in the arc-shaped sliding groove.

[0012] Furthermore, the transverse drive assembly includes a second servo motor, a second drive gear, and a rack support plate. The second servo motor is rotatably mounted on the first base plate, the second drive gear is fixedly mounted on the output end of the second servo motor, and the rack support plate is fixedly mounted on the top surface of the first base plate in a transverse direction. The rack support plate is provided with a first rack arranged in a transverse direction, and the second drive gear meshes with the first rack.

[0013] Furthermore, the lifting, sliding and rotating drive mechanism also includes a second base plate and a work frame vertically fixed on the top surface of the second base plate. The top of the cylinder is connected to the top of the work frame, and the driven large gear is rotatably mounted on the bottom end of the second base plate through a provided bearing seat.

[0014] Furthermore, the lifting drive mechanism includes a top slide, a column vertically fixedly installed on the top slide, a third servo motor fixedly installed on the column, and a third drive gear. The bottom end face of the top slide and the top end face of the frame form a sliding connection along the conveying direction of the engine tray. The third drive gear is fixedly installed at the output end of the third servo motor. A second rack arranged vertically is fixedly installed on the work frame. The third drive gear meshes with the second rack.

[0015] Furthermore, it also includes a connecting seat, through which the column is fixedly installed on the top slide.

[0016] Furthermore, it also includes a ball screw assembly, which includes a fourth servo motor, a ball screw, and a ball screw nut.

[0017] Furthermore, a temporary pallet storage rack is provided at the bottom end of the frame, away from the end where the engine tray enters.

[0018] The beneficial effects of this utility model are as follows:

[0019] By adopting the aforementioned engine pallet material handling device, the operator can control the lifting slide and the first servo motor in the rotary drive mechanism to rotate forward or reverse. This allows the driven large gear and rotating base plate to rotate and fine-tune the first base plate below. The hooks located at the corners of the bottom surface of the first base plate rotate and fine-tune synchronously with the first base plate to align with the hooks on the engine pallet. Subsequently, the lateral drive assembly drives the first base plate to move laterally, engaging the hooks with the hooks on the engine pallet. The entire adjustment process is highly automated, convenient, and quick, eliminating the need for manual adjustment of the engine pallet's placement. This solves the problems of low automation, low work efficiency, and high labor intensity caused by the existing method of manually adjusting engine pallets with positional deviations on AGV transport vehicles.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] See appendix Figure 1 Appendix Figure 2 Appendix Figure 4 and appendix Figure 5 As shown, this embodiment provides an engine pallet loading and unloading device 10, including a frame 200, a lifting drive mechanism 400, a lifting slide and a rotation drive mechanism 300, a cylinder 600, and a rotating and lateral lifting device 500.

[0041] See attached document Figure 1 The frame 200 is surrounded by guardrails to prevent the equipment from colliding with personnel during operation and causing injury.

[0042] See attached document Figure 1 To be continued Figure 3 As shown, a temporary pallet storage rack 201 is provided at the bottom of the frame 200, opposite to the AGV transport vehicle entry point. The temporary pallet storage rack 201 is used to temporarily store engine pallets, improving the transfer efficiency of engine pallets. (See attached diagram.) Figure 3 As shown, for example, during the engine pallet outbound operation, the engine pallet to be outbound can be taken out of the shelf and temporarily placed on the pallet temporary storage rack 201 before the AGV transport vehicle reaches the bottom of the rack 200. After the AGV transport vehicle arrives, the engine pallet stored on the pallet temporary storage rack 201 can be directly transferred to the AGV transport vehicle, avoiding the long operation time and low efficiency caused by the operation mode of taking the engine pallet from the shelf for transfer and storage after the AGV transport vehicle arrives.

[0043] See attached document Figure 1 Appendix Figure 2 and appendix Figure 6As shown, in this embodiment, the lifting drive mechanism 400 is arranged on the top surface of the frame 200. Specifically, the lifting drive mechanism 400 includes a top slide 401, a column 402 vertically fixed on the top slide 401, a third servo motor 404 fixed on the column 402, and a third drive gear 405. A linear guide rail is provided between the bottom surface of the top slide 401 and the top surface of the frame 200. The linear guide rail is arranged parallel to the conveying direction of the engine tray, so that the top slide 401 can slide relative to the frame 200.

[0044] See attached document Figure 2 and attached Figure 3 As shown, the top slide 401 is powered by a ball screw assembly mounted on the top surface of the frame 200. The ball screw assembly is arranged on the outer side of the top slide 401, i.e., along a direction parallel to the linear guide rail. Specifically, the ball screw assembly includes a fourth servo motor, a ball screw, and a ball screw nut. The fourth servo motor is fixedly mounted on the top surface of the frame 200, and the ball screw is rotatably mounted on the top surface of the frame 200. One end of the ball screw is connected to the output shaft of the fourth servo motor, and the ball screw nut is mounted on the ball screw and fixedly connected to one side of the top slide 401.

[0045] In this way, when the fourth servo motor drives the ball screw to rotate, the rotating ball screw will drive the ball screw nut mounted on it to move linearly, and the ball screw nut in the linear movement state will then synchronously drive the top slide 401 to move along the frame 200.

[0046] Continue to refer to the appendix Figure 1 Appendix Figure 2 and appendix Figure 6 As shown, the column 402 is vertically arranged on the top slide 401. The column 402 is fixedly installed on the top slide 401 through the connecting seat 403. That is, the top end of the connecting seat 403 is fixedly connected to the outer side of the column 402, and the bottom end of the connecting seat 403 is fixedly installed on the upper surface of the top slide 401.

[0047] The third servo motor 404 is horizontally fixed on the column 402, and the third drive gear 405 is fixedly installed on one end of the output shaft of the third servo motor 404, and the third drive gear 405 is driven to rotate by the third servo motor 404.

[0048] See attached document Figure 4 Appendix Figure 5 and appendix Figure 9As shown, in this embodiment, the lifting slide and rotary drive mechanism 300 includes a first servo motor 304, a first drive gear 305, a second base plate 302, and a work frame 301 vertically fixed on the top surface of the second base plate 302. The work frame 301 extends vertically upward from the top surface of the second base plate 302, and one side of the work frame 301 is vertically slidably mounted on the column 402 via a linear guide rail, that is, the work frame 301 can be lifted and moved relative to the column 402.

[0049] Continue to refer to the appendix Figure 4 Appendix Figure 5 and appendix Figure 9 As shown, in this embodiment, a second rack 303 is vertically installed on one side of the work frame 301 adjacent to the column 402, and a third drive gear 405 meshes with the second rack 303.

[0050] In this embodiment, since the top slide 401 is slidably mounted on the top surface of the frame 200, the top slide 401 cannot move up and down relative to the frame 200 in the vertical direction. Therefore, when the third servo motor 404 drives the third drive gear 405 to rotate, since the third servo motor 404 is fixedly mounted on the column 402, and the column 402 cannot move in the vertical direction relative to the frame 200, as the third drive gear 405 rotates forward or backward, the second rack 303 will move upward or downward relative to the third drive gear 405. The second rack 303, which is in the vertical movement, will synchronously drive the work frame 301 to move up and down.

[0051] See attached document Figure 5 As shown, one end of the piston rod of cylinder 600 is connected to the top of the work frame 301, and the bottom end of cylinder 600 is fixedly installed on the top slide table 401. In this way, the work frame 301 can be moved up and down by the extension and retraction of the piston rod of cylinder 600.

[0052] In this embodiment, cylinder 600 is used to drive the work frame 301 to move up and down significantly, mainly for the initial position of the work frame 301; while the cooperation between the third drive gear 405 and the second rack 303 is used for the lifting and lowering of the end position of the work frame 301 (grabbing the engine tray).

[0053] See attached document Figure 4 As shown, the first servo motor 304 is fixedly mounted on the second base plate 302. The output shaft of the first servo motor 304 extends vertically downward through the second base plate 302. The first drive gear 305 is fixedly mounted on the output shaft of the first servo motor 304. The first drive gear 305 is used to cooperate with the rotating horizontal lifting device 500 to provide power for the horizontal rotation of the rotating horizontal lifting device 500.

[0054] See attached document Figure 4 Appendix Figure 7 and appendix Figure 8 As shown, in this embodiment, the rotating and lateral lifting device 500 includes a first base plate 503, four hooks 504 fixedly installed at the corners of the bottom surface of the first base plate 503, a rotating base plate 502 arranged parallel above the first base plate 503, a driven large gear 501, and a lateral drive assembly.

[0055] The driven gear 501 is rotatably and fixedly installed at the bottom end of the second base plate 302 in the lifting slide and rotary drive mechanism 300 via a bearing seat. That is, the driven gear 501 can rotate horizontally relative to the second base plate 302 via the bearing seat, and the bearing seat is fixedly installed at the bottom end of the second base plate 302. In this way, when the work frame 301 drives the second base plate 302 to move up and down relative to the machine frame 200, the driven gear 501 will also move up and down synchronously with the work frame 301 to drive the hook 504 below to move up and down.

[0056] Simultaneously, the bottom surface of the driven gear 501 is fixedly connected to the upper surface of the rotating base plate 502, so that the driven gear 501, which is in a horizontal rotating state, will synchronously drive the rotating base plate 502 to rotate horizontally. The first base plate 503 forms a lateral sliding connection with the rotating base plate 502 through a sliding component 505. The lateral movement drive component is connected to the first base plate 503, and the first driving gear 305 meshes with the driven gear 501 to provide power for the rotation of the driven gear 501.

[0057] See attached document Figure 4 and attached Figure 10 As shown, in this embodiment, the rotating base plate 502 has an arc-shaped sliding groove 510 that extends vertically, and the end of the output shaft of the first servo motor 304 is slidably mounted in the arc-shaped sliding groove 510. The arc-shaped sliding groove 510 is provided to avoid interference between the rotating base plate 502, which is in a rotating state, and the end (bottom) of the output shaft of the first servo motor 304, which is in a fixed state, when the first servo motor 304 drives the first driving gear 305 to drive the driven large gear 501 to rotate horizontally. That is, when the rotating base plate 502 rotates horizontally, the end of the output shaft of the first servo motor 304 can slide along the arc-shaped sliding groove 510.

[0058] See attached document Figure 7 and attached Figure 8As shown, the transverse drive assembly includes a second servo motor 508, a second drive gear 509, and a rack support plate 506. The second servo motor 508 is rotatably mounted on the first base plate 503 via a provided bearing seat. The second drive gear 509 is fixedly mounted on the output end of the second servo motor 508. The rack support plate 506 is fixedly mounted on the top surface of the first base plate 503 in a transverse direction. A first rack 507 is provided on the rack support plate 506 in a transverse direction. The second drive gear 509 meshes with the first rack 507.

[0059] See attached document Figure 3 and attached Figure 4 As shown, when the hook 504 needs to be hooked onto the boom 21 on the engine tray, the first base plate 503 needs to first lower to a suitable height so that the hook 504 and the boom 21 on the engine tray are at the same height. The hook 504 also needs to be horizontally spaced forward or backward relative to the boom 21 so that the hook 504 can move laterally and horizontally into the boom 21, thereby driving the boom 21 to move vertically upward or downward. In this embodiment, the function of the lateral drive assembly is to drive the first base plate 503 to move horizontally, thereby driving the hook 504 to move laterally and horizontally into or out of the boom 21.
