Description

Technical Field

[0001] The utility model relates to the technical field of warehousing, and in particular to an intelligent warehousing shelf access mechanical arm. Background Art

[0002] When the smart storage shelves are in use, using a robotic arm to store and retrieve goods is more convenient than manual storage and retrieval of goods. However, general robotic arms are similar to forklifts and can only store and retrieve sticky boards on the shelves, which greatly limits the use of the device. Summary of the invention

[0003] The purpose of the utility model is to provide an intelligent storage shelf access robot arm to solve the problems raised in the above-mentioned background technology.

[0004] An intelligent storage shelf access robot arm comprises a frame and a support frame: a hydraulic pump and a battery are respectively arranged on one side of the upper end of the frame, a support frame is arranged on the other side of the upper end of the frame, a power mechanism is arranged inside the frame, a lifting mechanism is arranged inside the support frame, a guide rail is slidably arranged inside the frame, the guide rail is located directly below the battery, and one end of the guide rail away from the support frame is a plane.

[0005] Preferably, the power mechanism includes a first motor and a roller, the first motor is arranged on the side of the frame, and the output end of the first motor is connected to the roller.

[0006] When the device is in use, the first motor drives the roller to rotate, thereby driving the device to move, so as to adjust the position of the device and pick up materials at different positions. The guide rail is fixed to the ground by bolts, and the guide rail can limit the frame to avoid misalignment of the frame when moving; the weight of the lifting mechanism can be balanced by the hydraulic pump and the battery.

[0007] Preferably, the lifting mechanism includes a sprocket, a chain and a bearing plate, the sprocket is rotatably arranged inside the support frame, the chain is arranged on the outside of the sprocket, the bearing plate is arranged on the outside of the chain, the bearing plate is in an "L" shape, and the bearing plate is located outside the support frame.

[0008] When the device is in use, the sprocket drives the chain to rotate, and the movement of the chain drives the movement of the carrying plate, thereby driving the movement of the material.

[0009] Preferably, a second motor is provided on the side of the support frame, a sun gear is provided on the side of the second motor, the side of the sun gear is connected to a planetary gear, the side of the planetary gear is meshingly connected to a coupling sleeve, the coupling sleeve is provided inside the support frame, a fixed plate is provided on the side of the planetary gear, and the fixed plate is connected to a sprocket.

[0010] When the device is in use, the second motor is used to drive the sun gear to rotate, and the sun gear drives the planetary gears to rotate. The planetary gears are limited by the combination sleeve to ensure the stability of the planetary gears during rotation. When the planetary gears rotate and move, they will drive the fixed plate to rotate, thereby driving the sprocket to rotate.

[0011] Preferably, hydraulic rods are symmetrically arranged on both sides of the supporting plate, the hydraulic rods are connected to the hydraulic pump, a branch pipe is slidably arranged inside the hydraulic rod, and a sealing ring is connected to the outside of the branch pipe, the two branch pipes on one side are connected, and a pressure valve is arranged inside the non-connected end of the branch pipe.

[0012] The horizontal branch pipe is a non-connection end, and the vertical branch pipe is a connection end. When the hydraulic oil enters the hydraulic rod, it will push the branch pipe to move. Due to the obstruction of the pressure valve, the hydraulic oil will not enter the branch pipe. When the branch pipe moves to the maximum position, as the hydraulic pressure in the hydraulic rod increases, the hydraulic oil will enter the branch pipe.

[0013] When the device returns to its original position, the pressure in the hydraulic rod will decrease, and the pressure valve will prevent the hydraulic oil in the branch pipe from flowing into the inside of the hydraulic rod. Only when the branch pipe returns to its original position and the pressure continues to decrease, the pressure valve will open and the hydraulic oil in the branch pipe can be pumped out.

[0014] The length of the hydraulic rod can be adjusted according to demand, and the initial position of the baffle can be adjusted by adjusting the connection position between the hydraulic rod and the bearing plate.

[0015] Preferably, a piston ring is provided inside the connecting end of the branch pipe, a push rod is connected to the side of the piston ring, a rotating shaft is rotatably provided inside the branch pipe, a baffle is provided on the side of the rotating shaft, a torsion spring is connected to one end of the side of the rotating shaft, and the other end of the torsion spring is connected to the branch pipe.

[0016] When the device is in use, when the oil pressure in the hydraulic rod increases, it will push the branch pipe outward, so that the branch pipe moves to the rear side of the goods to be picked up, and then increase the oil pressure to move the piston ring and the push rod to drive the baffle to deflect. At this time, as the oil pressure decreases, the branch pipe will shrink, thereby driving the material to move to the surface of the load-bearing plate through the baffle; conversely, when it is necessary to store items, the rotating shaft is opened first, and then the rotating shaft is moved to drive the material to move, thereby pushing the material onto the shelf.

[0017] The beneficial effects of the utility model are:

[0018] 1. When the device is in use, the baffle is opened by hydraulic pressure, and then the goods are stored and retrieved by controlling the movement of the branch pipe. The device can only move laterally along the slide rail, thereby increasing the stability of the device when in use. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] When implementing: Figure 1-6As shown, an intelligent storage shelf access robot arm includes a frame 1 and a support frame 6: a hydraulic pump and a battery 4 are respectively arranged on one side of the upper end of the frame 1, and the support frame 6 is arranged on the other side of the upper end of the frame 1. A power mechanism is arranged inside the frame 1, and a lifting mechanism is arranged inside the support frame 6. A guide rail 5 is slidably arranged inside the frame 1, and the guide rail 5 is located directly below the battery 4, and the end of the guide rail 5 away from the support frame 6 is a plane.

[0028] The power mechanism includes a first motor 2 and a roller 3 . The first motor 2 is arranged on the side of the frame 1 , and the output end of the first motor 2 is connected to the roller 3 .

[0029] When the device is in use, the first motor 2 drives the roller 3 to rotate, thereby driving the device to move, so as to adjust the position of the device, so as to take materials at different positions. The guide rail 5 is fixed to the ground by bolts, and the guide rail 5 can limit the frame 1, thereby avoiding the misalignment of the frame 1 when moving; the weight of the lifting mechanism can be balanced by the hydraulic pump and the battery 4.

[0030] The lifting mechanism includes a sprocket 12, a chain 13 and a bearing plate 14. The sprocket 12 is rotatably arranged inside the support frame 6, the chain 13 is arranged on the outside of the sprocket 12, and the bearing plate 14 is arranged on the outside of the chain 13. The bearing plate 14 is "L"-shaped and is located outside the support frame 6.

[0031] When the device is in use, the sprocket 12 drives the chain 13 to rotate, and the movement of the chain 13 drives the movement of the carrying plate 14, thereby driving the movement of the material.

[0032] A second motor 7 is arranged on the side of the support frame 6, a sun gear 8 is arranged on the side of the second motor 7, the side of the sun gear 8 is connected to a planetary gear 9, the side of the planetary gear 9 is meshingly connected with a coupling sleeve 10, the coupling sleeve 10 is arranged inside the support frame 6, a fixed plate 11 is arranged on the side of the planetary gear 9, and the fixed plate 11 is connected to a sprocket 12.

[0033] When the device is in use, the second motor 7 is used to drive the sun gear 8 to rotate, and the sun gear 8 drives the planetary gear 9 to rotate, and the planetary gear 9 is limited by the combination sleeve 10 to ensure the stability of the planetary gear 9 during rotation. When the planetary gear 9 rotates, it will drive the fixed plate 11 to rotate, thereby driving the sprocket 12 to rotate.

[0034] Hydraulic rods 15 are symmetrically arranged on both sides of the supporting plate 14, and the hydraulic rods 15 are connected to the hydraulic pump. A branch pipe 16 is slidably arranged inside the hydraulic rod 15, and a sealing ring is connected to the outer side of the branch pipe 16. The two branch pipes 16 on one side are connected, and a pressure valve 17 is arranged inside the non-connected end of the branch pipe 16.

[0035] The horizontal branch pipe 16 is a non-connection end, and the vertical branch pipe 16 is a connection end. When the hydraulic oil enters the hydraulic rod 15, it will push the branch pipe 16 to move. Due to the obstruction of the pressure valve 17, the hydraulic oil will not enter the branch pipe 16. When the branch pipe 16 moves to the maximum position, as the hydraulic pressure in the hydraulic rod 15 increases, the hydraulic oil will enter the branch pipe 16.

[0036] When the device returns to its original position, the pressure in the hydraulic rod 15 will decrease, and the pressure valve 17 will prevent the hydraulic oil in the branch pipe 16 from flowing into the inside of the hydraulic rod 15. Only when the branch pipe 16 returns to its original position and the pressure continues to decrease, the pressure valve 17 opens and the hydraulic oil in the branch pipe 16 can be pumped out.

[0039] When the device is in use, when the oil pressure in the hydraulic rod 15 increases, the branch pipe 16 will be pushed outward, so that the branch pipe 16 moves to the rear side of the goods to be picked up, and then the oil pressure is increased to move the piston ring 18 and the push rod 19 to drive the baffle 20 to deflect. At this time, as the oil pressure decreases, the branch pipe 16 will shrink, thereby driving the material to move to the surface of the carrier plate 14 through the baffle 20; conversely, when it is necessary to store items, the rotating shaft 21 is first opened, and then the rotating shaft 21 is moved to drive the material to move, thereby pushing the material onto the shelf.
