Description

Technical Field

[0001] The present invention relates to the technical field of logistics robots, and specifically relates to a mobile loading robot for logistics assembly. Background Art

[0002] In a highly automated logistics warehouse, in order to improve the loading efficiency, loading robots are used to replace manual labor. The AGV intelligent robot forklift is a commonly used loading device, which is similar to an ordinary pallet jack forklift and moves goods through two fork plates.

[0003] In this regard, Chinese Patent Application No.: CN202310750579.2 discloses a warehousing logistics automatic handling robot, which relates to the technical field of handling robots and includes a main body. A sliding block is slidably connected to the main body, a connection box is fixedly connected to the sliding block, two groups of symmetrically arranged moving blocks are slidably connected to the connection box, a connecting plate is fixedly connected to the moving block, a support plate is fixedly connected to the connecting plate, and a rotating shaft is rotatably connected to the connecting plate. One end of the rotating shaft is fixedly connected to a turning plate, and the other end of the rotating shaft is connected to a turning member. In this warehousing logistics automatic handling robot, by providing an air extraction member, during the transportation process of the main body, when the main body is handling an object, a suction force can be applied to the object through the flowing air, avoiding the object from sliding due to inertia when the main body suddenly stops during transportation, and thus solving the problem that the object is prone to slipping off the main body due to inertia after sudden stop in the prior art.

[0004] This device can adsorb the goods on the turning plate by providing an air extraction member to avoid the goods from slipping. However, in actual logistics operations, there are situations where goods are stacked and moved. However, the air extraction member is located on the turning plate, and after the goods are stacked, only the goods at the bottommost side will contact the turning plate. Therefore, only the bottommost goods can be effectively adsorbed and fixed, and for the upper goods, they will still be displaced and dropped due to inertia. Therefore, the use scenario of the existing device is relatively limited and it is difficult to be widely promoted and used.

[0005] Therefore, in order to solve the above problems, a mobile loading robot for logistics assembly is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a mobile loading robot for logistics assembly, so as to solve the problem in the prior art proposed in the above background technology.

However, in actual logistics operations, there will be situations where goods are stacked and moved. However, the air extraction member is located on the turning plate, and after the goods are stacked, only the goods at the bottom will contact the turning plate. Therefore, only the goods at the bottom can be effectively adsorbed and fixed. For the upper goods, they will still displace and fall due to inertia. Therefore, the use scenario of the existing device is relatively limited and it is difficult to be widely promoted and used.

The adsorption structure includes a connecting plate, the connecting plate is movably installed at the upper end inside the support frame through a rotating shaft, on the right side wall of the connecting plate, an air extraction hole is opened, outside the air extraction hole, an activity cavity is opened, on the inner wall of the activity cavity, a second spring is fixedly connected, at one end of the second spring, a push cylinder is fixedly connected, on the inner wall of the push cylinder, a guide groove is opened, inside the air extraction hole, a fixed shielding plate is fixedly installed, on the right side wall of the fixed shielding plate, a movable shielding plate is rotatably installed, at the edge of the movable shielding plate, a guide rod is fixedly connected, on the top surface of the robot forklift main body, an air extraction pump is fixedly installed, and the air extraction end of the air extraction pump is connected with a conduit.

[0008] Preferably, a guide wheel is movably installed inside the bottom surface of the moving block, on the right side wall of the moving block, a first spring is fixedly connected, on the surface of the moving plate, a through groove is opened, on the top surface of the fork plate, a straight rack plate is fixedly installed, on the top surface of the moving plate, a loading plate is arranged, at the bottom surface of the loading plate, an arc rack plate is fixedly installed, and inside the through groove, a gear is rotatably installed.

[0009] Preferably, the bottom surface of the guide wheel is attached to the inner wall of the chute, and one end of the first spring is fixedly connected to the inner wall of the chute.

[0010] Preferably, the straight rack plate is located inside the through groove, and the straight rack plate meshes with the bottom surface of the gear.

[0011] Preferably, the loading plate is fixedly installed at the bottom end of the right side wall of the connecting plate, and the top surface of the gear meshes with the arc rack plate.

[0012] Preferably, the left end of the push cylinder is slidably installed inside the movable cavity, the right end of the push cylinder exposes the right side wall of the connecting plate, and a sealing gasket is arranged on the right side wall of the push cylinder.

[0013] Preferably, the fixed shutter and the movable shutter are staggered and adapted to each other. The guide rod penetrates the inner wall of the air extraction hole and is slidably installed inside the guide groove.

[0014] Preferably, one end of the conduit is connected to the left side wall of the connecting plate, and the inside of the conduit communicates with the inside of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by providing a connecting plate capable of adsorbing goods, the present invention can maintain an adsorption effect on a plurality of stacked goods in the height direction, improve the placement stability of the goods, and at the same time provide an inclined loading plate, which can tilt the goods in the opposite direction of the moving direction when the device suddenly stops, increasing the resistance of the goods to inertial displacement, further ensuring the moving stability of the goods, and being beneficial to improving the economic benefits of the enterprise.

[0016] A robotic forklift body, an inclination structure and an adsorption structure are provided. Multiple goods are stacked on the top surface of the loading plate and pushed to the left so that the left side wall of the goods fits against the right side wall of the push cylinder. The goods will push the push cylinder, causing the left end of the push cylinder to retract into the movable cavity. The push cylinder will compress the second spring. The guide rod is slidably installed in the guide groove. Therefore, when the push cylinder drives the guide groove to move, the guide rod will slide in the guide groove, and the guide rod will drive the movable shutter to rotate relative to the fixed shutter, causing the movable shutter and the fixed shutter to overlap each other, and the inside of the air extraction hole will be unobstructed. At this time, the guide rod is opened, and the air in the connecting plate can be pumped out through the air extraction pump. The inside of the connecting plate is in negative pressure, and the stacked goods can be tightly adsorbed on the right side wall of the connecting plate, making the placement of the goods on the loading plate more stable. And because the opening method of the movable shutter is rotation in the vertical direction, it will not be displaced and opened due to the influence of the air pressure inside the connecting plate, ensuring that the push cylinder that does not contact the goods, its corresponding fixed shutter and movable shutter can keep the inside of the air extraction hole blocked, and further ensuring the relative sealing inside the connecting plate and the adsorption stability of the goods; when the device moves, the support frame cooperates with the connecting plate to push the goods on the left side, so that the goods can move stably with the device, avoiding the goods from shifting and falling to the left due to the sudden movement of the device; when the device makes an emergency stop, the inclination structure, the adsorption structure and the goods will generate a rightward force under the action of inertia. At this time, the moving block will move to the right in the chute by rolling the guide wheel. The moving block will compress the first spring, and the moving block will drive the moving plate to move to the right. The moving plate will drive the loading plate to move relative to the straight rack plate. The bottom surface of the gear in the through groove meshes with the straight rack plate. Therefore, when the moving plate moves, it will drive the gear to roll clockwise on the straight rack plate. The top surface of the gear meshes with the arc rack plate. Therefore, the gear will drive the loading plate and the connecting plate to tilt counterclockwise on the support frame through the arc rack plate. The loading plate cooperates with the connecting plate to drive the goods to tilt counterclockwise. Since the tilting direction is opposite to the moving direction, the influence of the inertia caused by the emergency stop on the placement stability of the goods can be reduced. At the same time, there is a large resistance to the upward displacement of the goods due to inertia, further ensuring the moving stability of the goods. Then the first spring will recover, driving the moving block, the moving plate, the gear, the loading plate and the connecting plate to reset, enabling the goods to move clockwise around the connection between the connecting plate and the support frame. And because the higher goods are closer to the connection between the connecting plate and the support frame, the upper goods move a shorter distance relative to the lower goods. Therefore, the stability of the upper goods can be further improved, effectively ensuring the use safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-9 , an embodiment provided by the present invention: The robot forklift main body 1, fork plate 11, roller 12 and air extraction pump 310 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0021] A mobile loading robot for logistics assembly, comprising: a robot forklift main body 1, a fork plate 11 is installed on the right side wall of the robot forklift main body 1, a roller 12 is installed at the right end of the fork plate 11, and a chute 13 is opened on the top surface of the fork plate 11; An inclined structure 2 is installed on the fork plate 11. The inclined structure 2 includes a moving block 21. The moving block 21 is movably installed inside the sliding groove 13. The top surface of the moving block 21 is fixedly connected with a moving plate 24. The left end of the top surface of the moving plate 24 is fixedly connected with a support frame 26. An adsorption structure 3 is installed on the inclined structure 2. The adsorption structure 3 includes a connecting plate 31. The connecting plate 31 is movably installed at the upper end inside the support frame 26 through a rotating shaft. An air extraction hole 32 is formed on the right side wall of the connecting plate 31. An activity cavity 33 is formed outside the air extraction hole 32. A second spring 34 is fixedly connected to the inner wall of the activity cavity 33. One end of the second spring 34 is fixedly connected with a push cylinder 35. A guide groove 36 is formed on the inner wall of the push cylinder 35. A fixed shutter 37 is fixedly installed inside the air extraction hole 32. A movable shutter 38 is rotatably installed on the right side wall of the fixed shutter 37. A guide rod 39 is fixedly connected to the edge of the movable shutter 38. An air extraction pump 310 is fixedly installed on the top surface of the robot forklift main body 1. The air extraction end of the air extraction pump 310 is connected with a conduit 311. By providing the connecting plate 31 capable of adsorbing goods, the adsorption effect can be maintained on multiple stacked goods in the height direction, which can improve the placement stability of the goods. At the same time, by providing the tiltable loading plate 28, when the device suddenly stops, the goods can be tilted in the opposite direction of the moving direction, increasing the resistance of the goods to inertial displacement, further ensuring the moving stability of the goods, which is beneficial to improving the economic benefits of the enterprise.

[0022] Furthermore, a guide wheel 22 is movably installed inside the bottom surface of the moving block 21. A first spring 23 is fixedly connected to the right side wall of the moving block 21. A through groove 25 is formed on the surface of the moving plate 24. A straight rack plate 27 is fixedly installed on the top surface of the fork plate 11. A loading plate 28 is arranged on the top surface of the moving plate 24. An arc rack plate 210 is fixedly installed on the bottom surface of the loading plate 28. A gear 211 is rotatably installed inside the through groove 25. The loading plate 28 cooperating with the connecting plate 31 can drive the goods to tilt counterclockwise. Since the tilting direction is opposite to the moving direction, the influence of inertia caused by sudden stop on the placement stability of the goods can be reduced. At the same time, there is a large resistance to the upward displacement of the goods due to inertia, further ensuring the moving stability of the goods.

[0023] Furthermore, the bottom surface of the guide wheel 22 is in contact with the inner wall of the sliding groove 13. One end of the first spring 23 is fixedly connected with the inner wall of the sliding groove 13. The guide wheel 22 can reduce the friction of the moving block 21 moving inside the sliding groove 13, making the tilting of the loading plate 28 more sensitive. The first spring 23 provides power for the reset of the loading plate 28 and gradually offsets the inertia of the loading plate 28 and the goods.

[0024] Furthermore, the straight rack plate 27 is located inside the through groove 25. The straight rack plate 27 meshes with the bottom surface of the gear 211. The movement of the moving plate 24 can drive the gear 211 to rotate, providing a force for the tilting of the loading plate 28.

[0025] Further, the loading plate 28 is fixedly installed at the bottom end of the right side wall of the connecting plate 31. The top surface of the gear 211 meshes with the arc-shaped rack plate 210. The rotation of the gear 211 can drive the loading plate 28 to tilt through the arc-shaped rack plate 210. The tilt of the loading plate 28 can drive the connecting plate 31 to tilt, so that the connecting plate 31 supports the goods obliquely and keeps the goods neatly arranged.

[0026] Further, the left end of the push cylinder 35 is slidably installed inside the movable cavity 33. The right end of the push cylinder 35 exposes the right side wall of the connecting plate 31. A sealing gasket is provided on the right side wall of the push cylinder 35. The push cylinder 35 can stably move inside the movable cavity 33 so that the guide groove 36 and the guide rod 39 are stably matched. The setting of the sealing gasket can ensure the sealing performance at the joint between the air extraction hole 32 and the goods.

[0027] Further, the fixed shutter 37 and the movable shutter 38 are staggered and adapted to each other. The guide rod 39 penetrates the inner wall of the air extraction hole 32 and is slidably installed inside the guide groove 36. When the fixed shutter 37 and the movable shutter 38 are staggered, the air extraction hole 32 can be blocked. The movement of the push cylinder 35 can drive the movable shutter 38 to rotate through the guide rod 39.

[0028] Further, one end of the conduit 311 is connected to the left side wall of the connecting plate 31, and the inside of the conduit 311 communicates with the inside of the connecting plate 31. The air extraction pump 310 can extract the air inside the connecting plate 31 through the conduit 311, making the inside of the connecting plate 31 in negative pressure.

[0029] Working principle: During use, multiple goods can be stacked on the top surface of the loading plate 28 and pushed to the left, so that the left side wall of the goods fits against the right side wall of the push cylinder 35, and the goods will push the push cylinder 35, causing the left end of the push cylinder 35 to retract into the movable cavity 33. The push cylinder 35 will compress the second spring 34. Since the guide rod 39 is slidably installed in the guide groove 36, when the push cylinder 35 drives the guide groove 36 to move, the guide rod 39 will slide in the guide groove 36, and the guide rod 39 will drive the movable shutter 38 to rotate relative to the fixed shutter 37, making the movable shutter 38 coincide with the fixed shutter 37, and the inside of the air extraction hole 32 will be unblocked. At this time, when the air extraction pump 310 is turned on, the air inside the connecting plate 31 can be extracted through the air extraction pump 310, and the inside of the connecting plate 31 will be in negative pressure, so that the stacked goods can be tightly adsorbed on the right side wall of the connecting plate 31, making the placement of the goods on the loading plate 28 more stable. And because the opening method of the movable shutter 38 is a vertical rotation, it will not be displaced and opened due to the influence of the air pressure inside the connecting plate 31. It can ensure that the push cylinder 35 that does not contact the goods, the corresponding fixed shutter 37 and the movable shutter 38 can keep the inside of the air extraction hole 32 blocked, and further ensure the relative sealing inside the connecting plate 31 and the adsorption stability of the goods. When the device moves, the support frame 26 cooperates with the connecting plate 31 to push the goods on the left side, so that the goods can move stably with the device, avoiding the goods from shifting and falling off to the left due to the sudden movement of the device. When the device makes an emergency stop, the inclined structure 2, the adsorption structure 3 and the goods will generate a rightward force under the action of inertia. At this time, the moving block 21 will move to the right in the chute 13 by the rolling of the guide wheel 22. The moving block 21 will squeeze the first spring 23, and the moving block 21 will drive the moving plate 24 to move to the right. The moving plate 24 will drive the loading plate 28 to move relative to the straight rack plate 27. The bottom surface of the gear 211 in the through groove 25 meshes with the straight rack plate 27. Therefore, when the moving plate 24 moves, it will drive the gear 211 to roll clockwise on the straight rack plate 27, and the top surface of the gear 211 meshes with the arc rack plate 210. Therefore, the gear 211 will drive the loading plate 28 and the connecting plate 31 to tilt counterclockwise on the support frame 26 through the arc rack plate 210. The loading plate 28 cooperating with the connecting plate 31 can drive the goods to tilt counterclockwise. Since the tilting direction is opposite to the moving direction, the influence of the inertia caused by the emergency stop on the placement stability of the goods can be reduced. At the same time, there is a large resistance to the upward displacement of the goods due to inertia, which further ensures the moving stability of the goods. Then the first spring 23 will recover, driving the moving block 21, the moving plate 24, the gear 211, the loading plate 28 and the connecting plate 31 to reset, enabling the goods to displace clockwise around the connection between the connecting plate 31 and the support frame 26. And since the goods at the higher position are closer to the connection between the connecting plate 31 and the support frame 26, the upper goods move a shorter distance relative to the lower goods, thereby further improving the stability of the upper goods and effectively ensuring the use safety of the device.

[0030] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the illustrations in the specification and the above description. However, any equivalent changes such as slight modifications, decorations and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
