Description

Technical Field

[0001] This invention relates to the field of transportation or storage devices, and more specifically to a battery high and low position conveying device. Background Technology

[0002] After the batteries are manufactured, they need to be transported to the packaging workshop for boxing and packaging. Currently, the industry commonly uses AGVs (Automated Guided Vehicles) as the conveying equipment for this stage. However, when AGVs are used in conjunction with the battery loading process, the following problems still exist:

[0003] 1. When AGV carts are used in conjunction with manual battery loading, workers rely on placing the batteries onto the AGV carts. This method is not only inefficient and physically demanding for workers, but also relies entirely on the worker's experience to control the positioning and placement force of the batteries. This makes it easy for improper operation to cause the batteries to collide with the AGV cart components, damaging the batteries and affecting their quality.

[0004] 2. When the AGV (Automated Guided Vehicle) is used to load batteries onto the conveyor belt, the batteries are transferred directly from the conveyor belt to the AGV. Due to the height difference between the conveyor belt and the AGV, a falling space is created. During this process, the batteries inevitably collide with each other, which can damage them and affect product quality.

[0005] 3. After the batteries are successfully loaded onto the AGV, due to the lack of effective fixation of the existing AGV's load-bearing structure for the arranged batteries, the batteries will shift, shake, or even collide with each other due to inertia during the AGV's transport process, especially during start-up, stop-start, and turning. Summary of the Invention

[0006] The present invention aims to provide a battery high-low position conveying device to solve the problem of easy bumping and damage to batteries during high-low position conveying in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A battery high and low position conveying device includes a top-level conveying mechanism and an AGV trolley, with the AGV trolley positioned below the top-level conveying mechanism. The top-level conveying mechanism includes a vertical lifting group and a conveyor belt. The conveyor belt receives batteries and conveys them to the vertical lifting group, which clamps the batteries and conveys them to the AGV trolley. The vertical lifting group includes a lifting bracket with a feed inlet on its top side, which is connected to the conveyor belt. A conveying disc is located inside the lifting bracket, and a lifting drive assembly for driving the conveying disc to rise and fall is mounted on the lifting bracket. The bottom of the conveying disc is open, and a movable conveying disc base plate that can be opened horizontally is provided at the opening. A clamping component for clamping the batteries is provided on the conveying disc base plate.

[0009] Preferably, as an improvement, the conveyor tray includes a flow guide frame, with an opening at the bottom of the conveyor tray inside the flow guide frame. A set of opposite sides on the inner wall of the flow guide frame has a sliding groove, and another set of opposite sides has a wire gathering groove. A hollow tube is installed inside the flow guide frame, and the wire gathering groove communicates with the hollow tube. An air pump is connected to the hollow tube. The bottom plate of the conveyor tray includes two oppositely arranged inflatable corrugated plates. The ends of the two inflatable corrugated plates that are far apart from each other are respectively connected to the two wire gathering grooves. Support rods are connected to the free ends of the two inflatable corrugated plates. Guide blocks are provided at both ends of the support rods. The two guide blocks are slidably connected in the two sliding grooves. A reset member is connected between the guide blocks and the ends of the sliding grooves. The reset member is used to drive the guide blocks back to the ends of the sliding grooves. After the two inflatable corrugated plates are inflated, they can unfold and their free ends close together to close the flow guide frame to support the battery.

[0010] Preferably, as an improvement, the two inflatable corrugated plates are deployed in the same direction as the length of the battery.

[0011] Preferably, as an improvement, the clamping component is an inflatable protrusion located at one end of two inflatable corrugated plates that are far apart from each other. The inflatable protrusion is connected to an air pump, and after being inflated, it can expand towards the center to clamp the battery.

[0012] Preferably, as an improvement, the lifting drive assembly includes multiple lifting screws, which are vertically arranged. The two ends of the lifting screws are rotatably connected to the top and bottom of the lifting bracket, respectively. Nuts are threaded onto the lifting screws. Collars are rotatably arranged at the four corners of the guide frame and are rotatably fitted onto the nuts. A lifting screw motor is installed on the top of the lifting bracket, and the output shaft of the lifting screw motor is connected to the lifting screws.

[0013] Preferably, as an improvement, the AGV includes a top-opening compartment with AGV drive wheels at the four corners of the compartment bottom. A central axle is rotatably mounted inside the compartment, and multiple bottom trays of a certain depth are arranged around the central axle. The bottom trays are arranged in an array around the central axle. Multiple guide rods are fixed on the central axle, and strip-shaped guide holes are opened on the guide rods along their length. A central shaft is fixed in the middle of the bottom of the bottom trays. A square guide rail is arranged at the bottom of the compartment around the central axle. The central shaft slides through the guide holes on the guide rods and its bottom end is slidably connected to the guide rail. A central axle motor is connected to the central axle, which drives the central axle to rotate. The rotation of the central axle can drive the bottom trays to rotate sequentially to the bottom of the lifting bracket to receive the battery.

[0014] Preferably, as an improvement, a flexible protective pad is provided on the inner bottom surface of the bottom tray, and an inflatable pad is provided on the inner side surface of the side wall of the bottom tray, and the inflatable pad is connected to an air pump.

[0015] Preferably, as an improvement, the height of the side wall of the bottom tray is greater than the height of the battery.

[0016] The beneficial effects of this plan are:

[0017] 1. This solution uses a top-level conveyor mechanism to vertically transport batteries with their length and width as the support surfaces. The conveyor belt, along with the conveyor disc and clamping components, stably transports the batteries downwards, achieving standardized battery arrangement and high-low position transfer. This eliminates the need for manual loading of batteries onto the AGV, improving efficiency and reducing labor intensity. Furthermore, the high-low position transfer also solves the problem of battery collisions caused by direct drop from the conveyor belt.

[0018] 2. The conveyor tray is designed with inflatable corrugated plates, support rods, guide blocks, and reset components. When inflated, the inflatable corrugated plates unfold to enclose the flow-guiding frame and support the battery; after deflation, the reset components pull the inflatable corrugated plates back, opening the opening to facilitate the transfer of the battery to the AGV trolley. This dynamic switching ensures stable battery support through the inflatable corrugated plates and reset components, while also allowing for smooth material feeding.

[0019] 3. An inflation protrusion connected to an air pump is installed at the end of the inflatable corrugated plate. After inflation, it expands towards the center to clamp the battery. The inflated protrusion fits snugly against the edge of the battery, allowing it to be stably placed on the conveyor tray, achieving stable battery transport. Furthermore, using the inflatable corrugated plate as the base plate of the conveyor tray, along with the inflatable protrusion for clamping, effectively buffers, absorbs, and disperses minor vibrations generated during transport, thus ensuring stable battery transport. In practical applications, the inflation amount can be adjusted according to the battery's size and weight to regulate the clamping force, achieving stable clamping of different batteries and expanding the applicability.

[0020] 4. The lifting drive assembly uses multiple lifting screws in conjunction with nuts and collars to convert the rotation of the lifting screw motor into the lifting action of the conveyor plate. The coordinated action of multiple lifting screws ensures that the conveyor plate is evenly stressed, ensuring that the battery is accurately positioned and the process is stable during vertical transport, reducing equipment vibration and improving the stability of battery transport.

[0021] 5. The AGV (Automated Guided Vehicle) trolley features multiple base trays arranged in an array around a central hub. Combined with guide rods, rails, and a central shaft, the rotating hub moves the base trays sequentially to the lifting bracket for receiving. This enables continuous batch transport of multiple batteries per trip, significantly improving transport efficiency. Furthermore, the design of the rails, guide rods, and central shaft ensures precise positioning of the base trays during rotation and receiving, preventing battery misalignment that could lead to collisions or failure to receive the batteries.

[0022] 6. The bottom of the tray is equipped with a flexible protective pad, and the inner wall has an inflatable pad. During battery drop impacts, AGV vibrations, or turns, the protective pad and inflatable pad absorb energy, reducing the risk of hard collisions between the battery and the tray. Simultaneously, the side walls of the tray are higher than the battery height, forming a semi-enclosed shape to further prevent the battery from tipping over. Furthermore, the inflatable pad on the inner wall of the tray can be inflated to compress the battery from all sides when the inflatable corrugated plate is pulled back, ensuring the battery remains stable during this process. After the inflatable corrugated plate is pulled back, the inflatable pad is deflated, allowing the battery to be smoothly placed into the bottom tray, and the conveyor tray to rise smoothly.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the embodiments.

[0029] Example

[0030] like Figure 1 As shown, a battery high-low position conveying device includes a top-level conveying mechanism 1 and an AGV trolley 2, with the AGV trolley 2 located below the top-level conveying mechanism 1. The top-level conveying mechanism 1 includes a vertical lifting group and a conveyor belt 4. The conveyor belt 4 is used to receive batteries 30 and convey the batteries 30 to the vertical lifting group, which is used to clamp the batteries 30 and convey them to the AGV trolley 2.

[0031] Specifically, the vertical lifting assembly includes a lifting bracket 5. Two feed inlets 7 are opened on the top side of the lifting bracket 5, each connected to a conveyor belt 4, thereby receiving batteries 30 from the two conveyor belts. A conveyor plate 6 is movably mounted inside the lifting bracket 5, and a lifting drive assembly is installed on the lifting bracket 5 to drive the conveyor plate 6 up and down. The bottom of the conveyor plate 6 is open, and a movable conveyor plate base that can be opened horizontally is provided at the opening. Clamping components for holding the batteries 30 are provided on the conveyor plate base.

[0032] Combination Figure 2 As shown, the lifting drive assembly includes multiple lifting screws 16, and in this embodiment, there are four lifting screws 16. The lifting screws 16 are vertically arranged, and the two ends of the four lifting screws 16 are respectively rotatably connected to the four corners of the top and bottom of the lifting bracket 5. Each lifting screw 16 is threaded with a nut. The four corners of the conveying disc 6 are rotatably installed with collars 17, and the four collars 17 are respectively rotatably sleeved on the nuts on the four lifting screws 16. The lifting screw motor is installed on the top of the lifting bracket 5, and the output shaft of the lifting screw motor is fixedly connected to the lifting screw 16.

[0033] In this embodiment, the conveyor tray 6 includes a flow guide frame 8. A set of opposite sides of the inner wall of the flow guide frame 8 has grooves 9, and another set of opposite sides has wire gathering grooves 10. A hollow tube is installed inside the flow guide frame 8, and the wire gathering grooves 10 communicate with the hollow tube. The hollow tube is connected to an air pump 11. The bottom plate of the conveyor tray includes two oppositely arranged inflatable corrugated plates 12 (plate-shaped corrugated tube structures that can expand and contract through their folds). The ends of the two inflatable corrugated plates 12 that are far apart from each other are respectively connected to the two wire gathering grooves 10. The free ends of the two inflatable corrugated plates 12 are connected to support rods 14. Guide blocks 13 are provided at both ends of the support rods 14. The two guide blocks 13 are slidably connected within the two grooves 9. A reset member is connected between the guide blocks 13 and the ends of the grooves 9. The reset member is used to drive the guide blocks 13 back to the ends of the grooves 9. The reset member is a spring. After the two inflatable corrugated plates 12 are inflated, they can expand and their free ends close together to close the flow guide frame 8 to support the battery 30. In this embodiment, the two inflatable corrugated plates 12 unfold in the same direction as the length direction of the battery 30 (within the direction of the battery 30). Figure 1 The status of the battery (30) should be taken as the standard. Figure 3 The direction indicated by the middle arrow is the conveying direction of the battery 30. The clamping component is an inflatable protrusion 15 that is glued and fixed to one end of the two inflatable corrugated plates 12 that are far apart from each other. The inflatable protrusion 15 is connected to an air pump. After being inflated, the inflatable protrusion 15 can expand towards the middle to clamp the battery 30.

[0034] Combination Figure 3 and Figure 4 As shown, the AGV trolley 2 includes a compartment 18 with an open top, and AGV drive wheels 19 are installed at the four corners of the bottom of the compartment 18. A spindle 20 is rotatably mounted at the bottom of the center position inside the compartment 18. Multiple bottom trays 21 with a certain depth are arranged around the spindle 20. Preferably, the height of the side wall of the bottom tray 21 is greater than the height of the battery 30 to stably load the battery 30. A flexible protective pad, such as a sponge pad, rubber pad, or silicone pad, is glued to the inner bottom surface of the bottom tray 21. An air pad 26 is glued to the inner side of the side wall of the bottom tray 21. An air pump is installed on the compartment 18. Each air pad 26 is connected to the air pump through an air pipe. A cable channel is provided at the bottom of the bottom tray 21 to store the air pipe. Each air pipe on the air pad 26 is equipped with a valve to individually control the inflation and deflation of the air pad 26 of a single bottom tray 21. The compartment 18 is equipped with a switch to individually control the opening and closing of each valve.

[0035] In practical applications, the number of bottom trays 21 can be selected. This embodiment uses eight bottom trays 21 as an example. The eight bottom trays 21 are arranged in an array around the central disc 20. Eight guide rods 23 are fixed on the central disc 20 (the number of guide rods 23 is the same as the number of bottom trays 21). The guide rods 23 have strip-shaped guide holes 22 along their length. A central shaft 25 is fixed at the center of the bottom of each bottom tray 21. A square guide rail 24 is installed at the bottom of the carriage 18 around the central disc 20. The eight central shafts 25 slide through the guide holes 22 on the corresponding guide rods 23 and their bottom ends slide in the guide rail 24. The central disc 20 is connected to a central disc motor, which drives the central disc 20 to rotate. The rotation of the central disc 20 can drive the bottom trays 21 to rotate sequentially to the bottom of the lifting bracket 5 to receive the battery 30.

[0036] Working principle:

[0037] In actual use, the equipment is fixed on the production line at the battery 30 unloading position by the frame, so that the conveyor belt 4 is connected to the unloading end of the conveyor belt at the unloading position. The battery 30 is directly transported from the conveyor belt on the production line to the conveyor belt 4. The AGV trolley 2 drives to the bottom of the top conveyor mechanism 1, so that a bottom tray 21 on it is aligned with the bottom of the lifting bracket 5 to receive the battery 30.

[0038] This embodiment takes the conveying of four batteries 30 at a time as an example. The conveyor belt 4 transports the four batteries 30 together onto the conveyor tray 6. At this time, the two inflatable corrugated plates 12 on the conveyor tray 6 are filled with gas. The gas overcomes the elasticity of the reset member, causing the two inflatable corrugated plates 12 to be in an unfolded state with their free ends pressed together. The batteries 30 can be stably supported on the conveyor tray 6. In actual use, the inflatable corrugated plates 12 are made of thicker rubber material to ensure the support effect. At the same time, shallow friction textures can be set on the surface to improve friction. After the batteries 30 are transported onto the inflatable corrugated plates 12, the inflatable protrusions 15 on both sides inflate. After the two inflatable protrusions 15 are inflated, they expand towards the middle, thereby pressing against the batteries 30 and achieving the clamping of the batteries 30.

[0039] Subsequently, the lifting screw motor drives the lifting screw 16 to rotate. Under the action of the lifting screw 16 and the nut, the conveyor plate 6, carrying the battery 30, moves steadily downwards until it is placed in an empty bottom tray 21 on the AGV trolley 2 below the conveyor plate 6, at which point the lifting screw motor stops. At this time, the air cushion 26 is first inflated, using the air cushion 26 to squeeze the surface of the battery 30 from all sides, thereby holding the battery 30 tightly so that the air-filled corrugated plate 12 below can be deflated and retracted. Then, the air pump 11 is controlled to draw back the gas in the air-filled corrugated plate 12, and the two support rods 14 are pulled back by the reset component, thereby causing the two air-filled corrugated plates 12 to separate and retract, and the opening at the bottom of the conveyor plate 6 opens. Then, some of the gas in the air cushion 26 is released so that the conveyor plate 6 can rise smoothly, and the battery 30 is smoothly placed in the bottom tray 21. After the conveyor tray 6 rises, the air cushion 26 is inflated again to make it stick tightly to the battery 30. Since the inner wall of the bottom tray 21 is equipped with a flexible protective pad and the side wall is equipped with an air cushion 26, the battery 30 can be effectively prevented from colliding.

[0040] After the batteries 30 are placed, the drive conveyor 6 rises to its initial position to receive the next batch of batteries 30. Simultaneously, the spindle motor drives the spindle 20 to rotate at a certain angle. The spindle 20 then rotates the guide slide rod 23, which, via the central shaft 25, pulls the bottom tray 21 to rotate along the guide rail 24. This rotates the next hollow bottom tray 21 to below the lifting bracket 5 to await loading the next batch of batteries 30. This process repeats until all the bottom trays 21 in the AGV trolley 2 are loaded with batteries 30. Then, the AGV trolley 2 departs from below the top-level conveyor mechanism 1, transporting the batteries 30 to the packaging workshop for packaging. The next empty AGV trolley 2 then drives to below the top-level conveyor mechanism 1 to load the subsequent batch of batteries 30.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
